This Month in Astronomical History is a short (~500 word) illustrated column hosted on the AAS website (https://had.aas.org/resources/astro-history). Its mission is to highlight people and events that have shaped the development of astronomy to convey a historical context to current researchers, to provide a resource for education and public outreach programs seeking to incorporate a historical perspective, and to share the excitement of astronomy with the public. Knowing how the astronomical journey has proceeded thus far allows current professionals to map where to go next and how to get there. The column charts the first part of this journey by celebrating anniversaries of births, discoveries, and deaths, and the technological advances that made discoveries possible. A new “Further Reading” section encourages readers to pursue subjects in greater depth and strengthens the articles as classroom resources.In the months preceding the 21 August 2017 solar eclipse, the column featured astronomical bodies that come between Earth and the Sun: 2004 Venus transit, the 1878 solar eclipse, and the search for the hypothetical planet Vulcan. Venusian transits were an early but technically challenging way to measure the astronomical unit, now easily done with radar-ranging. Like this year’s event, eclipse chasing and citizen science were part of the 1878 experience. Newton’s Laws seemed to require a planet inside Mercury’s orbit, but General Relativity explained the behavior of Mercury without it. Studying each of these transiting bodies has expanded our knowledge and understanding of the universe differently. Transiting extrasolar planets remain to be explored in a future column. In September, an article on the discovery of Neptune followed the discussion of the non-existent Vulcan quite naturally and expanded on the brief mention of this event in relation to the discovery of Pluto. Suggestions for additional topics are always welcome.The Dudley Observatory
In this entertaining parody of letters to a typical “lonely hearts” columnist, real-life expert and long-time astronomy columnist Steve Ringwood presents a sweeping overview of common questions and problems practical and amateur astronomers face, compiled from Ringwood's own experiences in the world of astronomy. His screamingly funny comments will keep you laughing out loud throughout, so be careful of reading this book in public! Written especially for troubled astronomers, but also accessible to anyone with an interest in space or astronomy, readers will easily recognize the difficulties they face and enjoy the humor being directed at them and their science.

We analyze data sharing practices of astronomers over the past fifteen years. An analysis of URL links embedded in papers published by the American Astronomical Society reveals that the total number of links included in the literature rose dramatically from 1997 until 2005, when it leveled off at around 1500 per year. The analysis also shows that the availability of linked material decays with time: in 2011, 44% of links published a decade earlier, in 2001, were broken. A rough analysis of link types reveals that links to data hosted on astronomers' personal websites become unreachable much faster than links to datasets on curated institutional sites. To gauge astronomers' current data sharing practices and preferences further, we performed in-depth interviews with 12 scientists and online surveys with 173 scientists, all at a large astrophysical research institute in the United States: the Harvard-Smithsonian Center for Astrophysics, in Cambridge, MA. Both the in-depth interviews and the online survey indicate that, in principle, there is no philosophical objection to data-sharing among astronomers at this institution. Key reasons that more data are not presently shared more efficiently in astronomy include: the difficulty of sharing large data sets; over reliance on non-robust, non-reproducible mechanisms for sharing data (e.g. emailing it); unfamiliarity with options that make data-sharing easier (faster) and/or more robust; and, lastly, a sense that other researchers would not want the data to be shared. We conclude with a short discussion of a new effort to implement an easy-to-use, robust, system for data sharing in astronomy, at theastrodata.org, and we analyze the uptake of that system to-date.

Amateur astronomers interested in learning more about astronomical spectroscopy now have the guide they need. It provides detailed information about how to get started inexpensively with low-resolution spectroscopy, and then how to move on to more advanced high-resolution spectroscopy. Uniquely, the instructions concentrate very much on the practical aspects of using commercially-available spectroscopes, rather than simply explaining how spectroscopes work. The book includes a clear explanation of the laboratory theory behind astronomical spectrographs, and goes on to extensively cover the practical application of astronomical spectroscopy in detail. Four popular and reasonably-priced commercially available diffraction grating spectrographs are used as examples. The first is a low-resolution transmission diffraction grating, the Star Analyser spectrograph. The second is an inexpensive fiber optic coupled bench spectrograph that can be used to learn more about spectroscopy. The third is a newcomer, the ALPY ...

Becoming certified as a patient-centered medical home now requires practices to measure how effectively they provide continuity of care. To understand how continuity can be improved, we studied the association between provider practice characteristics and interpersonal continuity using the Usual Provider Continuity Index (UPC). We conducted a mixed-methods study of the relationship between provider practice characteristics and UPC in 4 university-based family medicine clinics. For the quantitative part of the study, we analyzed data extracted from monthly provider performance reports for 63 primary care providers (PCPs) between July 2009 and June 2010. We tested the association of 5 practice parameters on UPC: (1) clinic frequency; (2) panel size; (3) patient load (ratio of panel size to clinic frequency); (4) attendance ratio; and (5) duration in practice (number of years working in the current practice). Clinic, care team, provider sex, and provider type (physicians versus nonphysician providers) were analyzed as covariates. Simple and multiple linear regressions were used for statistical modeling. Findings from the quantitative part of the study were validated using qualitative data from provider focus groups that were analyzed using sequential thematic coding. There were strong linear associations between UPC and both clinic frequency (β = 0.94; 95% CI, 0.62-1.27) and patient load (β = -0.37; 95% CI, -0.48 to -0.26). A multiple linear regression including clinic frequency, patient load, duration in practice, and provider type explained more than 60% of the variation in UPC (adjusted R(2) = 0.629). UPC for nurse practitioners and physician assistants was more strongly dependent on clinic frequency and was at least as high as it was for physicians. Focus groups identified 6 themes as other potential sources of variability in UPC. Variability in UPC between providers is strongly correlated with variables that can be modified by practice managers. Our study

Astronomical Spectroscopy for Amateurs is a complete guide for amateur astronomers who are looking for a new challenge beyond astrophotography. The book provides a brief overview of the history and development of the spectroscope, then a short introduction to the theory of stellar spectra, including details on the necessary reference spectra required for instrument testing and spectral comparison. The various types of spectroscopes available to the amateur are then described. Later sections cover all aspects of setting up and using various types of commercially available and home-built spectroscopes, starting with basic transmission gratings and going through more complex models, all the way to the sophisticated Littrow design. The final part of the text is about practical spectroscope design and construction. This book uniquely brings together a collection of observing, analyzing, and processing hints and tips that will allow the amateur to build skills in preparing scientifically acceptable spectra data. It...

The phrase "blind astronomer” is used as an allegorical oxymoron. However, there were and are blind astronomers. What of famous blind astronomers? First, it must be stated that these astronomers were not martyrs to their craft. It is a myth that astronomers blind themselves by observing the Sun. As early as France's William of Saint-Cloud (circa 1290) astronomers knew that staring at the Sun was ill-advised and avoided it. Galileo Galilei did not invent the astronomical telescope and then proceed to blind himself with one. Galileo observed the Sun near sunrise and sunset or through projection. More than two decades later he became blind, as many septuagenarians do, unrelated to their profession. Even Isaac Newton temporarily blinded himself, staring at the reflection of the Sun when he was a twentysomething. But permanent Sun-induced blindness? No, it did not happen. For instance, it was a stroke that left Scotland's James Gregory (1638-1675) blind. (You will remember the Gregorian telescope.) However, he died days later. Thus, blindness little interfered with his occupation. English Abbot Richard of Wallingford (circa 1291 - circa 1335) wrote astronomical works and designed astronomical instruments. He was also blind in one eye. Yet as he further suffered from leprosy, his blindness seems the lesser of Richard's maladies. Perhaps the most famous professionally active, blind astronomer (or almost blind astronomer) is Dominique-Francois Arago (1786-1853), director until his death of the powerful nineteenth-century Paris Observatory. I will share other _ some poignant _ examples such as: William Campbell, whose blindness drove him to suicide; Leonhard Euler, astronomy's Beethoven, who did nearly half of his life's work while almost totally blind; and Edwin Frost, who "observed” a total solar eclipse while completely sightless.

Feedback is an essential component of education. It is designed to influence, reinforce, and change behaviors, concepts, and attitudes in learners. Although providing constructive feedback can be challenging, it is a learnable skill. The negative consequences of destructive feedback or lack of feedback all together are far-reaching. This article summarizes the components of constructive feedback and provides readers with tangible skills to enhance their ability to give effective feedback to learners and peers.

Just as quetzals and jaguars require specific ecological habitats to survive, so too must planets occupy a tightly constrained astronomical habitat to support life as we know it. With this theme in mind we relate the transferable features of our elementary astronomy course, "The Astronomical Basis of Life on Earth." Over the last five years, in a team-taught course that features a spring break field trip to Costa Rica, we have introduced astronomy through "astronomical ecosystems," emphasizing astronomical constraints on the prospects for life on Earth. Life requires energy, chemical elements, and long timescales, and we emphasize how cosmological, astrophysical, and geological realities, through stabilities and catastrophes, create and eliminate niches for biological life. The linkage between astronomy and biology gets immediate and personal: for example, studies in solar energy production are followed by hikes in the forest to examine the light-gathering strategies of photosynthetic organisms; a lesson on tides is conducted while standing up to our necks in one on a Pacific beach. Further linkages between astronomy and the human timescale concerns of biological diversity, cultural diversity, and environmental sustainability are natural and direct. Our experience of teaching "astronomy as habitat" strongly influences our "Astronomy 101" course in Oklahoma as well. This "inverted astrobiology" seems to transform our student's outlook, from the universe being something "out there" into something "we're in!" We thank the SNU Science Alumni support group "The Catalysts," and the SNU Quetzal Education and Research Center, San Gerardo de Dota, Costa Rica, for their support.

Steve Jobs is inarguably the greatest inventor and creative genius since Thomas Edison. He provided technology that enhances communication on a global level. Jobs also provided ideas and suggestions that could work in any medical practice regardless of the size of the practice, the location of the practice, or the employment model. His advice can be transferred from a high-tech business that employs thousands to a high-touch medical practice that has only a few employees. This article will list a few of Jobs leadership characteristics and how they might apply to physicians, their teams, and their practices. Wouldn't you like to be the Steve Jobs of healthcare?

Human trafficking is a global issue, with survivors representing all genders, ages, races, ethnicities, religions, and countries. However, little research exists that identifies effective practices in supporting survivors of human trafficking. The research that does exist is Western-centric. To fill this gap in the literature, the goal of this research was to understand practices used throughout the globe with adult human trafficking survivors. A qualitative approach was utilized. Providers from 26 countries, across six different continents, were interviewed to allow for a comprehensive and multi-faceted understanding of practices in working with survivors. Participants identified utilizing an empowerment-based, survivor, and human life-centered approach to working with survivors, emphasized the importance of engaging in community level interventions, and highlighted the importance of government recognition of human trafficking. Findings provide information from the perspective of advocates on best practices in the field that can be used by agencies to enhance human trafficking programming.

Buprenorphine office-based opioid maintenance is an increasingly common form of treatment for opioid use disorders. However, total prescribing has not kept pace with the current opioid and overdose epidemic and access remains scarce among the underserved. This study sought to assess current provider attitudes and clinical practices among a targeted sample of primarily New York City public sector buprenorphine prescribers. A cross-sectional online survey purposefully sampled buprenorphine prescribers in NYC with a focus on those serving Medicaid and uninsured patient populations. Expert review of local provider networks, snowball referrals, and in-person networking generated an email list, which received a survey link. A brief 25-question instrument queried provider and practice demographics, prescribing practices including induction approaches and attitudes regarding common hot topics (e.g., buprenorphine diversion, prescriber patient limits, insurance issues, ancillary treatments). Of 132 email invitations, N=72 respondents completed (n=64) or partially completed (n=8) the survey between January and April 2016. Most (79%) were Medicaid providers in non-psychiatric specialties (72%), working in a hospital-based or community general practice (51%), and board-certified in addiction medicine or psychiatry (58%). Practice sizes were generally 100 patients or fewer (71%); many providers (64%) individually prescribed buprenorphine Buprenorphine diversion was not rated as an important practice barrier. In conclusion, this targeted survey of buprenorphine prescribers in NYC treating primarily underserved populations showed a consistent pattern of part-time prescribing to modest volumes of patients, routine use of unobserved buprenorphine induction, and primarily elective referrals to psychosocial counseling. Barriers to prescribing included prior authorization requirements, lack of clinical resources (space, staff) and psychiatric services. Federal and local efforts to

Primary care physicians (PCPs) may not adequately counsel or monitor patients regarding diet, physical activity, and weight control (i.e., provide energy balance care). We assessed the organization of PCPs' practices for providing this care. The study design was a nationally representative survey conducted in 2008. The study setting was U.S. primary care practices. A total of 1740 PCPs completed two sequential questionnaires (response rate, 55.5%). The study measured PCPs' reports of practice resources, and the frequency of body mass index assessment, counseling, referral for further evaluation/management, and monitoring of patients for energy balance care. Descriptive statistics and logistic regression modeling were used. More than 80% of PCPs reported having information resources on diet, physical activity, or weight control available in waiting/exam rooms, but fewer billed (45%), used reminder systems (energy balance care. A total of 26% reported regularly assessing body mass index and always/often providing counseling as well as tracking patients for progress related to energy balance. In multivariate analyses, PCPs in practices with full electronic health records or those that bill for energy balance care provided this care more often and more comprehensively. There were strong specialty differences, with pediatricians more likely (odds ratio, 1.78; 95% confidence interval, 1.26-2.51) and obstetrician/gynecologists less likely (odds ratio, 0.28; 95% confidence interval, 0.17-0.44) than others to provide energy balance care. PCPs' practices are not well organized for providing energy balance care. Further research is needed to understand PCP care-related specialty differences.

Mindfulness practice, where an individual maintains openness, patience, and acceptance while focusing attention on a situation in a nonjudgmental way, can improve symptoms of anxiety, burnout, and depression. The practice is relevant for health care providers; however, the time commitment is a barrier to practice. For this reason, brief mindfulness interventions (eg, ≤ 4 hours) are being introduced. We systematically reviewed the literature from inception to January 2017 about the effects of brief mindfulness interventions on provider well-being and behavior. Studies that tested a brief mindfulness intervention with hospital providers and measured change in well-being (eg, stress) or behavior (eg, tasks of attention or reduction of clinical or diagnostic errors) were selected for narrative synthesis. Fourteen studies met inclusion criteria; 7 were randomized controlled trials. Nine of 14 studies reported positive changes in levels of stress, anxiety, mindfulness, resiliency, and burnout symptoms. No studies found an effect on provider behavior. Brief mindfulness interventions may be effective in improving provider well-being; however, larger studies are needed to assess an impact on clinical care. Published by Elsevier Inc.

The Astronomical Instrumentation System Markup Language (AISML) is an Extensible Markup Language (XML) based file format for maintaining and exchanging information about astronomical instrumentation. The factors behind the need for an AISML are first discussed followed by the reasons why XML was chosen as the format. Next it's shown how XML also provides the framework for a more precise definition of an astronomical instrument and how these instruments can be combined to form an Astronomical Instrumentation System (AIS). AISML files for several instruments as well as one for a sample AIS are provided. The files demonstrate how AISML can be utilized for various tasks from web page generation and programming interface to instrument maintenance and quality management. The advantages of widespread adoption of AISML are discussed.

Little is known about abortion practice in Mexico postlegalization of abortion in Mexico City in 2007. In 2009, we anonymously surveyed 418 Mexican health care providers at the Colegio Mexicano de Especialistas en Ginecologia y Obstetricia meeting using audio computer-assisted self-interview technology. The majority of respondents were obstetrician gynecologists (376, 90%), Catholic (341, 82%), 35-60 years old (332, 79%) and male (222, 53%) and worked with trainees (307, 74%). Prior to 2007, 11% (46) and 17% (71) provided medical and surgical abortions; now, 15% (62) and 21% (86) provide these services, respectively. Practitioners from Mexico City were more likely to provide services than those from other areas. Most medical abortion providers (50, 81%) used ineffective protocols. Surgical abortion providers mainly used either manual vacuum aspiration (39, 45%) or sharp curettage (27, 32%). Most abortion providers were trained in residency and wanted more training in medical (54, 87%) and surgical (59, 69%) abortion. Among nonproviders, 49% (175) and 27% (89) expressed interest in learning to perform medical and surgical abortion, respectively. Given the interest in learning to provide safe abortion services and the prevalent use of ineffective medical abortion regimens and sharp curettage, abortion training in Mexico should be strengthened.

Hand hygiene is an important component of infection control efforts. Our primary and secondary goals were to determine the reported rates of hand washing and stethoscope cleaning in emergency medical services (EMS) workers, respectively. We designed a survey about hand hygiene practices. The survey was distributed to various national EMS organizations through e-mail. Descriptive statistics were calculated for survey items (responses on a Likert scale) and subpopulations of survey respondents to identify relationships between variables. We used analysis of variance to test differences in means between the subgroups. There were 1,494 responses. Overall, reported hand hygiene practices were poor among pre-hospital providers in all clinical situations. Women reported that they washed their hands more frequently than men overall, although the differences were unlikely to be clinically significant. Hygiene after invasive procedures was reported to be poor. The presence of available hand sanitizer in the ambulance did not improve reported hygiene rates but improved reported rates of cleaning the stethoscope (absolute difference 0.4, p=0.0003). Providers who brought their own sanitizer were more likely to clean their hands. Reported hand hygiene is poor amongst pre-hospital providers. There is a need for future intervention to improve reported performance in pre-hospital provider hand washing.

Obesity is associated with the development and risk of death from several women's cancers. The study objective was to describe and compare oncologic providers' attitudes and practices as they relate to obesity counseling and management in cancer survivors. Society of Gynecologic Oncology members (n = 924) were surveyed with the use of a web-based, electronic questionnaire. χ(2) and Fisher exact tests were used to analyze responses. Of the 240 respondents (30%), 92.9% were practicing gynecologic oncologists or fellows, and 5.1% were allied health professionals. Median age was 42 years; 50.8% of the respondents were female. Of the respondents, 42.7% reported that they themselves were overweight/obese and that ≥50% of their survivor patients were overweight/obese. Additionaly, 82% of the respondents believed that discussing weight would not harm the doctor-patient relationship. Most of the respondents (95%) agreed that addressing lifestyle modifications with survivors is important. Respondents believed that gynecologic oncologists (85.1%) and primary care providers (84.5%) were responsible for addressing obesity. More providers who were ≤42 years old reported undergoing obesity management training (P 42 years old (P = .017). After initial counseling, 81.5% of the respondents referred survivors to other providers for obesity interventions. Oncology provider respondents believe that addressing obesity with cancer survivors is important. Providers believed themselves to be responsible for initial counseling but believed that obesity interventions should be directed by other specialists. Further research is needed to identify barriers to care for obese cancer survivors and to improve physician engagement with obesity counseling in the "teachable moment" that is provided by a new cancer diagnosis.

We argue that social marketing can be used as a generic framework for analysing barriers to the take-up of clinical guidelines, and planning interventions which seek to enable this change. We reviewed the literature on take-up of clinical guidelines, in particular barriers and enablers to change; social marketing principles and social marketing applied to healthcare. We then applied the social marketing framework to analyse the literature and to consider implications for future guideline policy to assess its feasibility and accessibility. There is sizeable extant literature on healthcare practitioners' non-compliance with clinical guidelines. This is an international problem common to a number of settings. The reasons for poor levels of take up appear to be well understood, but not addressed adequately in practice. Applying a social marketing framework brings new insights to the problem." We show that a social marketing framework provides a useful solution-focused framework for systematically understanding barriers to individual behaviour change and designing interventions accordingly. Whether the social marketing framework provides an effective means of bringing about behaviour change remains an empirical question which has still to be tested in practice. The analysis presented here provides strong motivation to begin such testing.

Traditional Aboriginal Australian cultures include a significant astronomical component, perpetuated through oral tradition and ceremony. This knowledge has practical navigational and calendrical functions, and sometimes extends to a deep understanding of the motion of objects in the sky. Here we explore whether this astronomical tradition is reflected in the rock art of Aboriginal Australians. We find several plausible examples of depictions of astronomical figures and symbols, and also evidence that astronomical observations were used to set out stone arrangements. However, we recognise that the case is not yet strong enough to make an unequivocal statement, and describe our plans for further research.

More than one third of American adults are obese. Extreme obesity is rapidly rising. Nine medications are approved for weight loss yet they remain underutilized with the focus primarily on lifestyle modifications. The objective was to determine current prescribing patterns and attitudes of weight loss medications in the management of obesity among primary care providers (PCPs). PCPs were surveyed to determine practice patterns, attitudes, barriers, and facilitators for prescribing weight loss medications. Ninety-four surveys were analyzed. Seventy-six percent of all PCPs did not prescribe weight loss medications for long-term weight loss and 58% of PCPs had negative perceptions of pharmacotherapy. Differences existed between prescribing patterns and attitudes of advanced practice clinicians and physicians. Safety concerns were the greatest barrier. Having 2+ comorbidities and severe obesity were facilitators for prescribing weight loss medications. Underutilization of pharmacotherapy suggests that PCPs may not have sufficient knowledge about medication safety profiles and efficacy. Delaying treatment until patients have reached a high level of morbidity may be less efficacious than earlier treatment. Education regarding effectiveness and risks of weight loss medications for obesity management is needed and earlier interventions with pharmacotherapy may prevent significant morbidity and mortality. ©2017 American Association of Nurse Practitioners.

Astronomer and science writer Dr. Helen Sawyer Hogg (University of Toronto) reached a variety of audiences through different rhetorical forms. She communicated to her colleagues through her scholarly writings; she reached out to students and the public through her Toronto Star newspaper column entitled "With the Stars," which she authored for thirty years; she wrote The Stars Belong to Everyone , a book that speaks to a lay audience; she hosted a successful television series entitled Ideas ; and she delivered numerous speeches at scientific conferences, professional women's associations, school programs, libraries, and other venues. Adapting technical information for different audiences is at the heart of technical communication, and Sawyer Hogg's work exemplifies adaptation as she moves from writing for the scientific community (as in her articles on globular cluster research) to science writing for lay audiences (as in her newspaper column, book, and script for her television series). Initially she developed her sense of audience through a male perspective informed largely by her scholarly work with two men (Harlow Shapley and her husband, Frank Hogg) as well as the pervasive masculine culture of academic science. This dissertation situates Sawyer Hogg in what is slowly becoming a canon of technical communication scholarship on female scientists. Toward this end, I discuss how she rhetorically engaged two different audiences, one scholarly and one popular, how Sawyer Hogg translated male dominated scientific rhetoric to writing for the public, and how science writing helped her achieve her professional goals. Complementing the archival research in addressing the questions of this study, I employ social construction analysis (also known as the social perspective) for my research methodology. She was ahead of her time and embodied the social perspective years before its definition as a rhetorical concept. In short, my study illuminates one scientific woman's voice

Like The Astronomical Almanac, The Explanatory Supplement provides detailed coverage of modern positional astronomy. Chapters are devoted to the celestial and terrestrial reference frames, orbital ephemerides, precession, nutation, Earth rotation, and coordinate transformations. These topics have undergone substantial revisions since the last edition was published. Astronomical positions are intertwined with timescales and relativity in The Astronomical Almanac, so related chapters are provided in The Explanatory Supplement. The Astronomical Almanac also includes information on lunar and solar eclipses, physical ephemerides of solar system bodies, and calendars, so T...
This valuable reference fills a number of needs in the field of astronomical eyepieces, including that of a buyer's guide, observer's field guide and technical desk reference. It documents the past market for eyepieces and its evolution right up to the present day. In addition to appealing to practical astronomers - and potentially saving them money - it is useful both as a historical reference and as a detailed review of the current market place for this bustling astronomical consumer product. What distinguishes this book from other publications on astronomy is the involvement of observers from all aspects of the astronomical community, and also the major manufacturers of equipment. It not only catalogs the technical aspects of the many modern eyepieces but also documents amateur observer reactions and impressions of their utility over the years, using many different eyepieces. Eyepieces are the most talked-about accessories and collectible items available to the amateur astronomer. No other item of equi...

Participation in a self-administered quality assessment (SAQA) program led to changes in New Jersey dentists' perceptions of practice quality. Ninety-four percent indicated they discovered practice deficiencies. This study suggests that using a self-administered quality assessment program, such as the SAQA program, can lead to a better understanding of a practice's strengths and weaknesses.
Amateur astronomy has changed beyond recognition in less than two decades. The reason is, of course, technology. Affordable high-quality telescopes, computer-controlled 'go to' mountings, autoguiders, CCD cameras, video, and (as always) computers and the Internet, are just a few of the advances that have revolutionized astronomy for the twenty-first century. Martin Mobberley first looks at the basics before going into an in-depth study of what’s available commercially. He then moves on to the revolutionary possibilities that are open to amateurs, from imaging, through spectroscopy and photometry, to patrolling for near-earth objects - the search for comets and asteroids that may come close to, or even hit, the earth. The New Amateur Astronomer is a road map of the new astronomy, equally suitable for newcomers who want an introduction, or old hands who need to keep abreast of innovations. From the reviews: "This is one of several dozen books in Patrick Moore's "Practical Astronomy" series. Amid this large family, Mobberley finds his niche: the beginning high-tech amateur. The book's first half discusses equipment: computer-driven telescopes, CCD cameras, imaging processing software, etc. This market is changing every bit as rapidly as the computer world, so these details will be current for only a year or two. The rest of the book offers an overview of scientific projects that serious amateurs are carrying out these days. Throughout, basic formulas and technical terms are provided as needed, without formal derivations. An appendix with useful references and Web sites is also included. Readers will need more than this book if they are considering a plunge into high-tech amateur astronomy, but it certainly will whet their appetites. Mobberley's most valuable advice will save the book's owner many times its cover price: buy a quality telescope from a reputable dealer and install it in a simple shelter so it can be used with as little set-up time as possible.

Younger primary school students often show great interest in the vast Universe hiding behind the starry night's sky, but don't have a way of learning about it and exploring it in regular classes. Some of them would search children's books, Internet or encyclopedias for information or facts they are interested in, but there are those whose hunger for knowledge would go unfulfilled. Such students were the real initiators of our extracurricular activity called Little Astronomers. With great enthusiasm they would name everything that interests them about the Universe that we live in and I would provide the information in a fun and interactive yet acceptable way for their level of understanding. In our class we learn about Earth and its place in the Solar System, we learn about the planets and other objects of our Solar System and about the Sun itself. We also explore the night sky using programs such as Stellarium, learning to recognize constellations and name them. Most of our activities are done using a PowerPoint presentation, YouTube videos, and Internet simulations followed by some practical work the students do themselves. Because of the lack of available materials and funds, most of materials are hand made by the teacher leading the class. We also use the school's galileoscope as often as possible. Every year the students are given the opportunity to go to an observatory in a town 90 km away so that they could gaze at the sky through the real telescope for the first time. Our goal is to start stepping into the world of astronomy by exploring the secrets of the Universe and understanding the process of rotation and revolution of our planet and its effects on our everyday lives and also to become more aware of our own role in our part of the Universe. The hunger for knowledge and enthusiasm these students have is contagious. They are becoming more aware of their surroundings and also understanding their place in the Universe that helps them remain humble and helps
The past fifty years have been an epoch of impressive progress in the field of astronomical technology. Practically all the technical tools, which we use today, have been developed during that time span. While the first half of this period has been dominated by advances in the detector technologies, during the past two decades innovative telescope concepts have been developed for practically all wavelength ranges where astronomical observations are possible. Further important advances can be ...
To explore and identify precedent factors that may influence nursing students' oral hygiene practice in hospitalised patients, by using an adaptation of the Precede Model. A quantitative approach with a descriptive design was adopted in this pilot study. A questionnaire was designed and implemented as a self-report method of data collection. A convenience sample of 37 second-year diploma nursing students in an Irish teaching hospital participated in the study. The clinical area and the practices within it are influential factors in the provision of oral hygiene. Students are exposed to and influenced by outdated and non-research-based practices. Role modelling is an effective means of motivating and reinforcing student practices. However, qualified nurses' practices need to be critically reviewed before assuming that they can act as role models in assisting students to implement research-based oral hygiene. Formal education, current practices, socialisation and role modelling may influence students' behaviour in relation to oral hygiene. The results should be tentatively reviewed by clinical staff as an indication of current practices.
As a casual read through any of the major amateur astronomical magazines will demonstrate, there are filters available for all aspects of optical astronomy. This book provides a ready resource on the use of the following filters, among others, for observational astronomy or for imaging: Light pollution filters Planetary filters Solar filters Neutral density filters for Moon observation Deep-sky filters, for such objects as galaxies, nebulae and more Deep-sky objects can be imaged in much greater detail than was possible many years ago. Amateur astronomers can take

The purpose of this study was to quantify, within the National Dental Practice-Based Research Network, current utilization of dental hygienists and assistants with expanded functions and quantify network dentists' attitudes toward a new nondentist provider model - the dental therapist. National Dental Practice-Based Research Network practitioner-investigators participated in a single, cross-sectional administration of a questionnaire. Current nondentist providers are not being utilized by network practitioner-investigators to the fullest extent allowed by law. Minnesota practitioners, practitioners in large group practices, and those with prior experience with expanded-function nondentist providers delegate at a higher rate and had more-positive perceptions of the new dental therapist model. Expanding scopes of practice for dental hygienists and assistants has not translated to the maximal delegation allowed by law among network practices. This finding may provide insight into dentists' acceptance of newer nondentist provider models. © 2013 American Association of Public Health Dentistry.

Chinese, Japanese and Korean celestial observations have made major contributions to Applied Historical Astronomy, especially in the study of supernovae, comets, Earth's rotation (using eclipses) and solar variability (via sunspots and aurorae). Few original texts now survive; almost all extant records exist only in printed versions, often with the loss of much detail. The earliest Chinese astronomical observations extend back to before 1000 BC. However, fairly systematic records are only available since 200 BC - and even these have suffered losses through wars, etc. By around AD 800, many independent observations are available from Japan and Korea and these provide a valuable supplement to the Chinese data. Throughout East Asia dates were expressed in terms of a luni-solar calendar and conversion to the Julian or Gregorian calendar can be readily effected.

To describe the use of a clinical decision-making work sheet as a tool to teach communication skills to advanced practice nurse (APN) students. Achievement of competencies in communication and documentation that utilize language and communication strategies that are shared with other health professionals promotes effective collaborative practice among members of the multidisciplinary provider team. Review of the recent Institute of Medicine report on health professions education and other health professional literature. The Clinical Decision-Making Work Sheet helps APN students effectively communicate in real-world clinical settings. The clinical work sheet allows nurse practitioner students to communicate more effectively and efficiently, using a vocabulary that is shared with other members of the multidisciplinary health care provider team. Use of the tool in students' clinical-rotation settings facilitates effective application and refinement of the clinical decision-making skills that students learned in the advanced health assessment course. Faculty have the responsibility to assist nurses as they transition from traditional nursing to APN roles. The work sheet facilitates learning the common language for data collection, clinical decision making, documentation, and reporting that is shared with other health professionals. Using the tool, students learn to efficiently organize information that supports communication and documentation that enhances their clinical problem-solving skills. Case presentation and documentation using the work sheet provide a basis for preceptor and student interaction and for student evaluation.
The last decade has seen a considerable growth in the application of e-learning courses in most higher education institutions and in companies that provide inhouse training for employees. Hereby recognition is given that modern information and telecommunication technologies can help educators to meet the dual
This text was written to provide students of astronomy and engineers an understanding of optical science - the study of the generation, propagation, control, and measurement of optical radiation - as it applies to telescopes and instruments for astronomical research in the areas of astrophysics, astrometry, exoplanet characterization, and planetary science. The book provides an overview of the elements of optical design and physical optics within the framework of the needs of the astronomical community.

Astronomical Optics and Elasticity Theory provides a very thorough and comprehensive account of what is known in this field. After an extensive introduction to optics and elasticity, the book discusses variable curvature and multimode deformable mirrors, as well as, in depth, active optics, its theory and applications. Further, optical design utilizing the Schmidt concept and various types of Schmidt correctors, as well as the elasticity theory of thin plates and shells are elaborated upon. Several active optics methods are developed for obtaining aberration corrected diffraction gratings. Further, a weakly conical shell theory of elasticity is elaborated for the aspherization of grazing incidence telescope mirrors. The very didactic and fairly easy-to-read presentation of the topic will enable PhD students and young researchers to actively participate in challenging astronomical optics and instrumentation projects.

The depiction of astronomers as characters in fiction during the last four centuries provides a useful historical indication of the changing popular perception of astronomy and its practitioners. It is apparent that lay attitudes to astronomy, even in any given period, are complex. On the one hand there is the continuing, innate attraction which the spectacle of the night sky has for people of all ages, the sense of wonder it generates and the preception of astronomy as a "pure" science, free from military and environmentally damaging spin-offs. But, on the other hand, astronomy poses particular and radical challenges to the humanist tradition and these have elicited from many writers not only expressions of anguish and confusion but, at times, a personal attack on the astronomers who were considered responsible for the unwelcome views.
Four hundred years ago in Middelburg, in the Netherlands, the telescope was invented. The invention unleashed a revolution in the exploration of the universe. Galileo Galilei discovered mountains on the Moon, spots on the Sun, and moons around Jupiter. Christiaan Huygens saw details on Mars and rings around Saturn. William Herschel discovered a new planet and mapped binary stars and nebulae. Other astronomers determined the distances to stars, unraveled the structure of the Milky Way, and discovered the expansion of the universe. And, as telescopes became bigger and more powerful, astronomers delved deeper into the mysteries of the cosmos. In his Atlas of Astronomical Discoveries, astronomy journalist Govert Schilling tells the story of 400 years of telescopic astronomy. He looks at the 100 most important discoveries since the invention of the telescope. In his direct and accessible style, the author takes his readers on an exciting journey encompassing the highlights of four centuries of astronomy. Spectacul...
and to provide a showcase for a broad range of astronomical research and celestial objects," Adams added. In addition, NRAO is developing enhanced data visualization techniques and data-processing recipes to assist radio astronomers in making quality images and in combining radio data with data collected at other wavelengths, such as visible-light or infrared, to make composite images. "We encourage all our telescope users to take advantage of these techniques to showcase their research," said Juan Uson, a member of the NRAO scientific staff and the observatory's EPO scientist. "All these efforts should demonstrate the vital and exciting roles that radio telescopes, radio observers, and the NRAO play in modern astronomy," Lo said. "While we want to encourage images that capture the imagination, we also want to emphasize that extra effort invested in enhanced imagery also will certainly pay off scientifically, by revealing subtleties and details that may have great significance for our understanding of astronomical objects," he added. Details of the NRAO Image Contest, which will become an annual event, are on the observatory's Web site. The observatory will announce winners on October 15. The National Radio Astronomy Observatory is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc.

In fifteenth century Korea, there was a grand project for the astronomical calendar and instrument making by the order of King Sejong 世宗 (1418-1450). During this period, many astronomical and calendrical books including Islamic sources in Chinese versions were imported from Ming 明 China, and corrected and researched by the court astronomers of Joseon 朝鮮 (1392-1910). Moreover, the astronomers and technicians of Korea frequently visited China to study astronomy and instrument making, and they brought back useful information in the form of new published books or specifications of instruments. As a result, a royal observatory equipped with 15 types of instrument was completed in 1438. Two types of calendar, Chiljeongsan Naepyeon 七政算內篇 and Chiljeongsan Oepyeon 七政算外篇, based on the Chinese and Islamic calendar systems, respectively, were published in 1444 with a number of calendrical editions such as corrections and example supplements (假令) including calculation methods and results for solar and lunar eclipses.

Over 1 in 5 dental patients report moderate to severe dental fear. Although the efficacy of cognitive-behavioral treatment (CBT) for dental fear has been examined in over 20 randomized controlled trials-with 2 meta-analyses finding strong average effect sizes ( d > 1)-CBT has received almost no dissemination beyond the specialty clinics that tested it. The challenge, then, is not how to treat dental fear but how to disseminate and implement such an evidence-based treatment in a way that recognizes the rewards and barriers in the US health care system. This mixed-method study investigated the potential of disseminating CBT through care from a mental health provider from within the dental home, a practice known as evidence-based collaborative care (EBCC). Two preadoption studies were conducted with practicing dentists drawn from a self-organized Practice-Based Research Network in the New York City metropolitan area. The first comprised 3 focus groups ( N = 17), and the second involved the administration of a survey ( N = 46). Focus group participants agreed that CBT for dental fear is worthy of consideration but identified several concerns regarding its appeal, feasibility, and application in community dental practices. Survey participants indicated endorsement of factors promoting the use of EBCC as a mechanism for CBT dissemination, with no factors receiving less than 50% support. Taken together, these findings indicate that EBCC may be a useful framework through which an evidence-based treatment for dental fear treatment can be delivered.

To satisfy the requirement of the astronomical observation, a novel timing sequence of frame transfer CCD is proposed. The multiple functions such as the adjustments of work pattern, exposure time and frame frequency are achieved. There are four work patterns: normal, standby, zero exposure and test. The adjustment of exposure time can set multiple exposure time according to the astronomical observation. The fame frequency can be adjusted when dark target is imaged and the maximum exposure time cannot satisfy the requirement. On the design of the video processing, offset correction and adjustment of multiple gains are proposed. Offset correction is used for eliminating the fixed pattern noise of CCD. Three gains pattern can improve the signal to noise ratio of astronomical observation. Finally, the images in different situations are collected and the system readout noise is calculated. The calculation results show that the designs in this paper are practicable.

In this paper, we discuss how certain astronomical concepts are related to the ancient Egyptian culture and their daily life. One of them is different ways of creating their calendar systems. The ancient Egyptian calendar seems to have quite a bit of its origin in astronomy and its development over the course of history. There is an important role played by events, as determined in the heavens, in developing their calendar system. Along with astronomical observations by the ancient people of Egypt, there were several outside cultures that helped develop their calendar system and Egyptian idea of how life was created on this planet, most notably the inclusion of the star Sirius in the constellation of Canis Major. We give a brief discussion of these influences. For the ancient Egyptians, the cycle of life and death is a concept that ties in with a calendar system used to determine daily events.

The traditional method of astronomical azimuth determination involves measurements at night to stars (Polaris). QDAEDALUS, developed by the team of the Geodesy and Geodynamics Lab (GGL, led by Prof. M. Rothacher) of ETH Zürich is a unique system combining Total Stations and modern CCD technique. It provides precise astronomical azimuths within 15 minutes of observation time at night. Furthermore, observations in daytime conditions are a challenging requirement in practice of Astro-geodetic azimuth determination. In order to perform daylight measurements, the QDAEDALUS system has been improved by allowing precise azimuth measurements to Sun, Moon, and Planets in daylight conditions by expanding the processing software with precise solar, lunar, and planetary ephemerides. With such functionality the system has a unique capability to measure astronomical azimuths with an accuracy of 0.3-0.5 arcsecs in normal daylight conditions within 20 to 25 minutes of measurement time.

The American Astronomical Society, with organizations active in EPO, has launched professional-development workshops and a community of practice to help improve early-career astronomers' ability to communicate effectively. Called “Astronomy Ambassadors,” the program provides mentoring and training for participants, from advanced undergraduates to beginning faculty. By learning to implement effective EPO strategies, Ambassadors become better teachers, meeting presenters, and representatives of our science to the public and government. Because young astronomers are a more diverse group than those who now do most outreach, they help the astronomy community present a more multicultural and gender-balanced face to the public, enabling underserved groups to see themselves as scientists. Ambassadors are given a library of outreach activities and materials, including many developed by cooperating organizations such as the ASP, plus some that have been created by Andrew Fraknoi specifically for this program.
These daytime astronomy activities arose from research done in New Zealand by a group of teachers and astronomers into the problems of teaching astronomy. This showed that it was generally regarded as a difficult subject to take, traditionally relying on books, films and models. The fortunate may have had a visit to an observatory or planetarium, the adventurous may have attempted an outdoor evening viewing session, which sometimes had weather-related difficulties. The problem of not having many 'hands-on' activities, the feelings of inadequate knowledge, the felt need for astronomical equipment and expertise become too daunting for many teachers to do the subject justice. If astronomy was to be taught then a way around these difficulties needed to be found. Our group, working with teachers and children using the constructivism teaching approach, found that the principles of astronomy could be discovered during the day when the students are at school. Working co-operatively they measured and recorded observations of their shadows caused by the motions and interactions of the nearest star, the Sun (Sol), and our planet, Earth. Because children were involved so personally they were much more interested in the results of the study. Astronomy became enthralling and challenging for both teacher and class after applying their daytime experiences to night time viewing at home and reporting back to class. Estas actividades astronómicas diurnas surgieron de una investigación hecha en NuevaZelandia por un grupo de maestros y astrónomos sobre los problemas de la enseñanza de la Astronomía. Este trabajo mostró que la Astronomía es generalmente considerada una disciplina difícil de enseñar, y tradicionalmente basada en libros, filmes y modelos. Los más afortunados pueden haber efectuado alguna visita a un observatorio o planetario, y los más aventajados pueden tal vez haber intentado una sesión de observación nocturna, las cuales sufren a veces de dificultades
Tokugawa Bakufu's astronomical office, established in 1684, is the post for calendar reform. The reform was conducted when the calendar did not predict peculiar celestial phenomena, such as solar or lunar eclipses. It was, so to speak, the theme of the ancient astronomy. From removal of the embargo on importing western science books in 1720, Japanese astronomers studied European astronomy and attempted to apply its knowledge to calendar making. Moreover, they knew the Copernican system and also faced several modern astronomical subjects. The French astronomer Lalande's work "ASTRONOMY" exerted particularly strong influence on astronomers. This paper overviews the activities of Paris observatory and French astronomers in the 17th and 18th centuries, and survey what modern astronomical subjects were. Finally, it sketches a role of the Edo observatory played in the Japanese cultural history.

search centre and a search radius. The search results are outputted into a main window of Aladin in textual and graphical forms using XML and Simple Object Access Protocol (SOAP). In this way, the NVO image server is integrated with other astronomical servers, using a special configuration file. The user may conveniently request information from many servers using the same server selector of Aladin, although the servers are located in different countries. Aladin has a wide range of special tools for data analysis and handling, including connection with other standalone applications. As a conclusion, we should note that a research team of a data centre, which provides the infrastructure for data output to the internet, is responsible for creation of corresponding archives. Therefore, each observatory or data centre has to provide an access to its archives in accordance with the IVOA standards and a resolution adopted by the IAU XXV General Assembly #B.1, titled: Public Access to Astronomical Archives. A research team of NAO copes successfully with this task and continues to develop the NVO. Using our databases and VO-tools, we also take part in development of the Ukrainian Virtual Observatory (UkrVO). All three main parts of the NVO are used as prototypes for the UkrVO. Informational resources provided by other astronomical institutions from Ukraine will be included in corresponding databases and VO interfaces.

Advanced Practice Registered Nurses (APRNs) and Physician Assistants (PAs), generally referred to as Advanced Practice Providers (APPs), are fundamental to interdisciplinary oncology care. As the projected demand for oncology services is anticipated to outpace the supply of oncologists, APPs will become increasingly vital in the delivery of oncology care and services. The training, education, and scope of practice for APPs gives the interdisciplinary care team professionals that deliver high-quality clinical services and provide valuable contributions and leadership to health care quality improvement initiatives. Optimizing the integration of APPs in oncology care offers immense advantages towards improvement of clinical outcomes.

Federal Equal Employment Opportunity laws and regulations do not provide protection from discrimination on the basis of sexual orientation or gender identity or gender expression. Sexual minority astronomers (including lesbian, gay, bisexual and transgender people; LGBT) can face additional challenges at school and work. Studies show that LGBT students on many campuses report experiences of harassment. Cities, counties, and states may or may not have statutes to protect against such discrimination. There is wide variation in how states and insurance plans handle legal and medical issues for transgender people. Federal law does not acknowledge same-sex partners, including those legally married in the U.S. or in other countries. Immigration rules in the U.S. (and many other, but not all) countries do not recognize same-sex partners for visas, employment, etc. State `defense of marriage act' laws have been used to remove existing domestic partner benefits at some institutions, or benefits can disappear with a change in governor. LGBT astronomers who change schools, institutions, or countries during their career may experience significant differences in their legal, medical, and marital status.
This book presents a systematic design methodology for decoding the interior structure of the Antikythera mechanism, an astronomical device from ancient Greece. The historical background, surviving evidence and reconstructions of the mechanism are introduced, and the historical development of astronomical achievements and various astronomical instruments are investigated. Pursuing an approach based on the conceptual design of modern mechanisms and bearing in mind the standards of science and technology at the time, all feasible designs of the six lost/incomplete/unclear subsystems are synthesized as illustrated examples, and 48 feasible designs of the complete interior structure are presented. This approach provides not only a logical tool for applying modern mechanical engineering knowledge to the reconstruction of the Antikythera mechanism, but also an innovative research direction for identifying the original structures of the mechanism in the future. In short, the book offers valuable new insights for all...

We present a general description of ground-based astronomical polarimeters, and provide a detailed description of the spectropolarimeter of the Main astronomical observatory (MAO) of a National Academy of Sciences of Ukraine (NASU). Using a polarization modulator of a rotating quarter-wave phase plate (FP) allows us to measure the parameters of linear and circular polarization simultaneously. In 1983 O. I. Bugaenko with the colleagues from MAO of NASU produced an automatic astronomical spectropolarimeter (ASP), which used a continuous rotation of polarizer with frequency of 61 Hz. Observations in two beam modes allowed it to accommodate changes of transparency of the Earth's atmosphere, air mass the of observational object, inexactness of guiding and displacement from an optical axis because of atmospheric turbulence. In 1995 the spectropolarimeter was upgraded and its spectral interval expanded to 1 micron. Sources of errors and methods of their elimination are described.

It is known that in the educational system of republic the astronomy is not taught as a separate subject. Moreover, there are no telescopes in the vast majority of schools. "Goodricke John" NGO of amateur astronomers tries to fill this gap by organizing practical lessons of astronomy in secondary schools. NGO is equipped with high quality portable amateur telescopes and organizes periodic mass observations of planets, Moon, star clusters, nebulae in Yerevan and in regions. In addition, mass observations of rare astronomical phenomena are organized, such as the transit of Venus and Mercury across the disk of the Sun. Being the only NGO of amateur astronomers, it has a goal to contribute to publicizing astronomical knowledge and to ensure the availability of astronomical equipment, telescopes also to those segments of the society who have no opportunity to deal with them, in particular, persons with disabilities, prisoners, persons with disabilities, prisoners, soldiers, children from orphanages, school children and others.

The earliest astronomical instruments used in India were the gnomon and the water clock. In the early seventh century, Brahmagupta described ten types of instruments, which were adopted by all subsequent writers with minor modifications. Contact with Islamic astronomy in the second millennium AD led to a radical change. Sanskrit texts began to lay emphasis on the importance of observational instruments. Exclusive texts on instruments were composed. Islamic instruments like the astrolabe were adopted and some new types of instruments were developed. Production and use of these traditional instruments continued, along with the cultivation of traditional astronomy, up to the end of the nineteenth century.

The numbers of nurse practitioners and physician assistants are increasing throughout the entire health care enterprise, and a similar expansion continues within radiology. Some practices have instead embraced radiologist assistants. The increased volume of services rendered by this growing nonphysician provider subset of the health care workforce within and outside of radiology departments warrants closer review. The authors evaluate the recent literature and offer recommendations to radiology practices regarding both regulatory and scope-of-practice issues related to these professionals. Additionally, billing and compliance issues for care provided by nurse practitioners, physician assistants, and radiologist assistants are detailed. An analysis of the integration of these professionals into interventional and diagnostic radiology practices, as well as potential implications for medical education, is provided in the second part of this series.

What stand out in the solid system of Gr. Narekatsi's naturalistic views are his astronomical insights on the material nature of light, its high speed and the Sun being composed of "material air". Especially surprising and fascinating are his views on stars and their clusters. What astronomers, including great Armenian academician V. Ambartsumian (scattering of stellar associations), would understand and prove with much difficulty thousand years later, Narekatsi predicted in the 10th century: "Stars appear and disappear untimely", "You who gather and scatter the speechless constellations, like a flock of sheep". Gr. Narekatsti's reformative views were manifested in all the spheres of the 10th century social life; he is a reformer of church life, great language constructor, innovator in literature and music, freethinker in philosophy and science. His ideology is the reflection of the 10th century Armenian Renaissance. During the 9th-10th centuries, great masses of Armenians, forced to migrate to the Balkans, took with them and spread reformative ideas. The forefather of the western science, which originated in the period of Reformation, is considered to be the great philosopher Nicholas of Cusa. The study of Gr. Narekatsti's logic and naturalistic views enables us to claim that Gr. Narekatsti is the great grandfather of European science.

La Plata, the current capital city of the province of Buenos Aires, was founded on 19 November 1882 by governor Dardo Rocha, and built on an innovative design giving emphasis to the quality of the public space, official and educational buildings. The Astronomical Observatory was one of the first inhabitants of the main park of the city; its construction started in 1883 including two telescopes that ranked among the largest in the southern hemisphere at that time and also several instruments devoted to positional astronomy (e.g. a meridian circle and a zenith telescope). A dedicated effort has being invested during the last 15 years in order to recover some of the original instrumentation (kept in a small museum) as well as the distinctive architectural values. In 1905, the Observatory, the School of Agriculture and the Museum of Natural Sciences (one of the most important museums in South America) became part of the backbone of La Plata National University, an institution with a strong and distinctive profile in exact and natural sciences. The First School for Astronomy and Related Sciences had been harboured by the Observatory since 1935, and became the current Faculty of Astronomical and Geophysical Sciences in 1983. This last institution carries PhD programs and also a number of teaching activities at different levels. These activities are the roots of a strong connection of the Observatory with the city.

This study explored which health care providers could be involved in centralized intake for patients with nonspecific low back pain to enhance access, continuity, and appropriateness of care. We reviewed the scope of practice regulations for a range of health care providers. We also conducted telephone interviews with 17 individuals representing ten provincial colleges and regulatory bodies to further understand providers' legislated scopes of practice. Activities relevant to triaging and assessing patients with low back pain were mapped against professionals' scope of practice. Family physicians and nurse practitioners have the most comprehensive scopes and can complete all restricted activities for spine assessment and triage, while the scope of registered nurses and licensed practical nurses are progressively narrower. Chiropractors, occupational therapists, physiotherapists, and athletic therapists are considered experts in musculoskeletal assessments and appear best suited for musculoskeletal specific assessment and triage. Other providers may play a complementary role depending on the individual patient needs. These findings indicate that an interprofessional assessment and triage team that includes allied health professionals would be a feasible option to create a centralized intake model. Implementation of such teams would require removing barriers that currently prevent providers from delivering on their full scope of practice.

The New York Astronomical Corporation was formed in 1968 by astronomers at New York State universities, colleges and observatories with the aim of building a large telescope for the use of astronomers in the state. Hawaii was selected as a possible site for a 150-in telescope and for a period of five years a vigorous effort was made at fund raising. A grant was received from the New York State Science and Technology Foundation to help in the organization of the group. By 1973 it was decided to stop plans for a New York Telescope since we had no success in the fund raising. However our group was already involved in holding meetings at the member institutions and staff and students would give reports on their work. In 1973 we formally set up the Astronomical Society of New York. Meetings are held twice a year. The Fall meeting is held at Union College or RPI and at this time the business meeting of NYAC is held. The Spring meeting is held at the other member institutions, from Alfred University in the west and the State University of New York at Stony Brook, in the east. The proceedings of the meetings are published in the News Letter of the Astronomical Society of New York. Prizes are awarded for the best graduate and the best undergraduate papers submitted to the Prize Committee. The winners give invited talks at a meeting following the award. Travel grants are awarded to both graduate and undergraduate students who are granted time to observe on optical or radio telescopes. ASNY has provided a good platform for students to give their first papers and by awarding the prizes and travel grants ASNY has been able to support student research. The meetings help to maintain good contacts among New York astronomers.

There are many factors driving health care reform, including unsustainable costs, poor outcomes, an aging populace, and physician shortages. These issues are particularly relevant to neurology. New reimbursement models are based on value and facilitated by the use of multidisciplinary teams. Integration of advanced practice providers (APPs) into neurology practice offers many advantages with new models of care. Conversely, there are many and varied challenges financially and logistically with these practice models. The American Academy of Neurology has formed a Work Group to address the needs of both neurologists and neurologic APPs and monitor the effect of APPs on quality and cost of neurologic care.

India is responsible for 30% of the annual global cohort of unvaccinated children worldwide. Private practitioners provide an estimated 21% of vaccinations in urban centers of India, and are important partners in achieving high vaccination coverage. We used an in-person questionnaire and on-site observation to assess knowledge, attitudes, and practices of private immunization service providers regarding delivery of immunization services in the urban settings of Surat and Baroda, in Gujarat, India. We constructed a comprehensive sampling frame of all private physician providers of immunization services in Surat and Baroda cities, by consulting vaccine distributors, local branches of physician associations, and published lists of private medical practitioners. All providers were contacted and asked to participate in the study if they provided immunization services. Data were collected using an in-person structured questionnaire and directly observing practices; one provider in each practice setting was interviewed. The response rate was 82% (121/147) in Surat, and 91% (137/151) in Baroda. Of 258 participants 195 (76%) were pediatricians, and 63 (24%) were general practitioners. Practices that were potential missed opportunities for vaccination (MOV) included not strictly following vaccination schedules if there were concerns about ability to pay (45% of practitioners), and not administering more than two injections in the same visit (60%). Only 22% of respondents used a vaccination register to record vaccine doses, and 31% reported vaccine doses administered to the government. Of 237 randomly selected vaccine vials, 18% had expired vaccine vial monitors. Quality of immunization services in Gujarat can be strengthened by providing training and support to private immunization service providers to reduce MOVs and improve quality and safety; other more context specific strategies that should be evaluated may involve giving feedback to providers on quality of services

Tennessee has a high incidence of Rocky Mountain spotted fever (RMSF), the most severe tick-borne rickettsial illness in the United States. Some regions in Tennessee have reported increased illness severity and death. Healthcare providers in all regions of Tennessee were surveyed to assess knowledge, attitudes, and perceptions regarding RMSF. Providers were sent a questionnaire regarding knowledge of treatment, diagnosis, and public health reporting awareness. Responses were compared by region of practice within the state, specialty, and degree. A high proportion of respondents were unaware that doxycycline is the treatment of choice in children ≤ 8 years of age. Physicians practicing in emergency medicine, internal medicine, and family medicine; and nurse practitioners, physician assistants, and providers practicing for < 20 years demonstrated less knowledge regarding RMSF. The gaps in knowledge identified between specialties, designations, and years of experience can help target education regarding RMSF.

Peru and France are to conclude an agreement to provide Peru with an astronomical observatory equipped with a 60-cm diameter telescope. The principal aims of this project are to establish and develop research and teaching in astronomy. Since 2004, a team of researchers from Paris Observatory has been working with the University of Cusco (UNSAAC) on the educational, technical and financial aspects of implementing this venture. During an international astronomy conference in Cusco in July 2009, the foundation stone of the future Peruvian Observatory was laid at the top of Pachatusan Mountain. UNSAAC, represented by its Rector, together with the town of Oropesa and the Cusco regional authority, undertook to make the sum of 300,000€ available to the project. An agreement between Paris Observatory and UNSAAC now enables Peruvian students to study astronomy through online teaching.

Quality improvement measures are uniformly applied to all oncology providers, regardless of their roles. Little is known about differences in adherence to these measures between oncology fellows, advance practice providers (APP), and attending physicians. We investigated conformance across Quality Oncology Practice Initiative (QOPI) measures for oncology fellows, advance practice providers, and attending physicians at the Durham Veterans Affairs Medical Center (DVAMC). Using data collected from the Spring 2012 and 2013 QOPI cycles, we abstracted charts of patients and separated them based on their primary provider. Descriptive statistics and the chi-square test were calculated for each QOPI measure between fellows, advanced practice providers (APPs), and attending physicians. A total of 169 patients were reviewed. Of these, 31 patients had a fellow, 39 had an APP, and 99 had an attending as their primary oncology provider. Fellows and attending physicians performed similarly on 90 of 94 QOPI metrics. High-performing metrics included several core QOPI measures including documenting consent for chemotherapy, recommending adjuvant chemotherapy when appropriate, and prescribing serotonin antagonists when prescribing emetogenic chemotherapies. Low-performing metrics included documentation of treatment summary and taking action to address problems with emotional well-being by the second office visit. Attendings documented the plan for oral chemotherapy more often (92 vs. 63%, P=0.049). However, after the chart audit, we found that fellows actually documented the plan for oral chemotherapy 88% of the time (p=0.73). APPs and attendings performed similarly on 88 of 90 QOPI measures. The quality of oncology care tends to be similar between attendings and fellows overall; some of the significant differences do not remain significant after a second manual chart review, highlighting that the use of manual data collection for QOPI analysis is an imperfect system, and there may

To investigate the attitudes and practices of cystic fibrosis (CF) providers toward sexual and reproductive health (SRH) care in young women with CF. Adult and pediatric US CF providers were sent an online survey exploring their attitudes toward SRH importance, SRH care practices, and barriers/facilitators to SRH care in adolescent and/or young adult women. Descriptive statistics and logistic regression were used to analyze results. Attitudes toward the importance of SRH care in patients with CF and self-report of practice patterns of SRH discussion. Respondents (n = 196) were 57% pediatric (111/196) and 24% adult physicians (48/196) and 19% nurse practitioners (NPs)/physician assistants (PAs) (37/196). Ninety-four percent of respondents believed SRH was important for female patients with CF (184/196). More than 75% believed SRH care should be standardized within the CF care model (147/196) and 41% believed the CF team should have the primary role in SRH discussion and care (80/196). For many CF-specific SRH topics, discrepancies emerged between how important respondents believed these were to address and how often they reported discussing these topics in practice. Significant differences in SRH attitudes and practices were present between adult and pediatric physicians. The most significant barriers to SRH care identified were lack of time (70%, 137/196) and the presence of family in clinic room (54%, 106/196). Potential facilitators included training materials for providers (68%, 133/196) and written (71%, 139/196) or online (76%, 149/196) educational resources for patients. CF providers perceive SRH topics as important to discuss, but identify barriers to routine discussion in current practice. Providers endorsed provider training and patient educational resources as means to improve SRH delivery. Copyright © 2017 North American Society for Pediatric and Adolescent Gynecology.

Supporting children's self-regulation in eating through caregivers' practice of responsive feeding is paramount to obesity prevention, and while much attention has been given to supporting children's self-regulation in eating through parents' responsive feeding practices in the home setting, little attention has been given to this issue in childcare settings. This qualitative study examines childcare providers' perspectives on using responsive feeding practices with young children (2-5years). Individual semi-structured interviews were conducted with providers until saturation was reached. Data was analyzed using thematic analysis. The final sample included 18 providers who were employed full-time in Head Start or state-licensed center-based childcare programs, cared for children (2-5y), and were directly responsible for serving meals and snacks. Providers were primarily (67%) employed in childcare programs that served children from low-income families and received reimbursement for meals and snacks from the US Department of Agriculture's Child and Adult Care Food Program. Three factors emerged that shaped childcare providers' experiences using responsive feeding practices: the providers' perspectives about whether or not young children can self-regulate food intake, their understanding of Child and Adult Care Food Program (CACFP) portion size regulations, and the availability of food at the center where they worked. Future research should examine how childcare providers' understanding of children's ability to self-regulate their food intake, the appropriate use of the CACFP regulations in relationship to serving sizes, and having food available to offer seconds promotes providers' use of responsive feeding practices in center-based childcare programs and children's dietary behaviors.

To examine vertical integration of teaching and clinical training in general practice and describe practical examples being undertaken by Australian general practice regional training providers (RTPs). A qualitative study of all RTPs in Australia, mid 2010. All 17 RTPs in Australia responded. Eleven had developed some vertical integration initiatives. Several encouraged registrars to teach junior doctors and medical students, others encouraged general practitioner supervisors to run multilevel educational sessions, a few coordinated placements, linkages and support across their region. Three RTPs provided case studies of vertical integration. Many RTPs in Australia use vertical integration of teaching in their training programs. RTPs with close associations with universities and rural clinical schools seem to be leading these initiatives.

The importance of involving young astronomers in developing astronomy cannot be overemphasized. This is very much true in areas where astronomy is still an emerging and minor field, such as in the Southeast Asian (SEA) region. However, recent years have seen a sudden spark of interest in developing professional astronomy within SEA, primarily for young astronomers and students. This was especially highlighted during the 2009 International Year of Astronomy. In this presentation, we introduce the Southeast Asian Young Astronomers Collaboration (SEAYAC), a recently formed organization that aims to provide a venue for professional and personal interaction for young astronomers in the SEA region. Here we present the background and rationale behind the formation of SEAYAC, its current status as well as planned future activities aimed at developing collaborations between young astronomers in the SEA region. We will also discuss the problems and challenges being faced by SEAYAC as well as its future plan of actions.

To investigate how inpatient palliative care teams nationwide currently screen for and treat psychological distress. A web-based survey was sent to inpatient palliative care providers of all disciplines nationwide asking about their practice patterns regarding psychological assessment and treatment. Descriptive statistics were used to characterize the sample and responses, and analysis of variance was conducted to determine whether certain disciplines were more likely to utilize specific treatment modalities. A total of N = 236 respondents were included in the final analyses. Providers reported that they encounter psychological distress regularly in their practice and that they screen for distress using multiple methods. When psychological distress is detected, providers reported referring patients to an average of 3 different providers (standard deviation = 1.46), most frequently a social worker (69.6%) or chaplain (65.3%) on the palliative care team. A total of 84.6% of physicians and 54.5% of nurse practitioners reported that they prescribe anxiolytics or selective serotonin reuptake inhibitors to patients experiencing psychological distress. This study revealed significant variability and redundancy in how palliative care teams currently manage psychological distress. The lack of consistency potentially stems from the variability in the composition of palliative care teams across care settings and the lack of scientific evidence for best practices in psychological care in palliative care. Future research is needed to establish best practices in the screening and treatment of psychological distress for patients receiving palliative care.

We present status and plans for our ongoing efforts to develop data analysis and problem-solving skills through Undergraduate Astronomy instruction. While our initiatives were developed with UM-Dearborn’s student body primarily in mind, they should be applicable for a wide range of institution and of student demographics. We focus here on two strands of our effort.Firstly, students in our Introductory Astronomy (ASTR 130) general-education course now perform several “Data Investigations”, in which they interrogate the Hubble Legacy Archive to illustrate important course concepts. This was motivated in part by the realization that typical public data archives now include tools to interrogate the observations that are sufficiently accessible that introductory astronomy students can use them to perform real science, albeit mostly at a descriptive level. We are continuing to refine these investigations, and, most importantly, to critically assess their effectiveness in terms of the student learning outcomes we wish to achieve. This work is supported by grant HST-EO-13758, provided by NASA through a grant from the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS 5-26555.Secondly, at the advanced-undergraduate level, students taking courses in our Astronomy minor are encouraged to gain early experience in techniques of astronomical observation and analysis that are used by professionals. We present two example projects from the Fall 2015 iteration of our upper-division course ASTR330 (The Cosmic Distance Ladder), one involving Solar System measurements, the second producing calibrated aperture photometry. For both projects students conducted, analysed, and interpreted observations using our 0.4m campus telescope, and used many of the same analysis tools as professional astronomers. This work is supported partly from a Research Initiation and Seed grant from the

We present the online forum astrobabel.com, which has the goal of being a gathering place for the collective community intelligence about astronomical computing. The audience for this forum is anyone engaged in the analysis of astronomical or planetary data, whether that data be observational or theoretical. It is a free, community driven site where discussions are formulated primarily around the "question and answer" format. Current topics on the forum range from “Is there a photometry package in Python?” to “Where are the support forums for astronomy software packages?” and “Why is my SDSS SkyQuery query missing galaxies?” The poster will detail the full scope of discussions in the forum, and provide some basic guidelines for ensuring high quality forum posts. We will highlight the ways astronomers can discover and participate in discussions. Further, we view this as an excellent opportunity to gather feedback and feature requests from AAS221 attendees. Acknowledgement: The Virtual Astronomical Observatory (VAO) is managed by the VAO, LLC, a non-profit company established as a partnership of the Associated Universities, Inc. and the Association of Universities for Research in Astronomy, Inc.

Eating during hemodialysis treatment remains a controversial topic. It is perceived that more restrictive practices in the United States contribute to poorer nutritional status and elevated mortality compared with some other parts of the world. However, in-center food practices in the United States have not been previously described. In 2011, we conducted a survey of clinic practices and clinician (dietitian, facility administrator, and medical director) opinions related to in-center food consumption within a large dialysis organization. After the initial survey, we provided clinicians with educational materials about eating during treatment. In 2014, we performed a follow-up survey. Differences in practices and opinions were analyzed using chi-squared tests and logistic regression. In 2011, 343 of 1199 clinics (28.6%) did not allow eating during treatment, 222 clinics (18.2%) did not allow drinking during treatment, and 19 clinics (1.6%) did not allow eating at the facility before or after treatment. In 2014, the proportion of clinics that did not allow eating during treatment had declined to 22.6% (321 of 1422 clinics), a significant shift in practice (Pnutritional status. Among clinicians, a higher percentage encouraged eating during treatment (53.1% versus 37.4%; P<0.05), and facility administrators and medical directors were less concerned about the seven reasons commonly cited for restricting eating during treatment in 2014 compared with 2011 (P<0.05 for all). We found that 28.6% and 22.6% of hemodialysis clinics within the United States restricted eating during treatment in 2011 and 2014, respectively, a rate more than double that found in an international cohort on which we previously published. However, practices and clinician opinions are shifting toward allowing patients to eat. Additional research is warranted to understand the effect that these practices have on patient outcomes and outline best practices. Copyright © 2016 by the American Society of

To systematically review the available evidence about hospital discharge communication practices and identify which practices were preferred by patients and healthcare providers, improved patient and provider satisfaction, and increased patients' understanding of their medical condition. OVID Medline, Web of Science, ProQuest, PubMed and CINAHL plus. Databases were searched for peer-reviewed, English-language papers, published to August 2016, of empirical research using quantitative or qualitative methods. Reference lists in the papers meeting inclusion criteria were searched to identify further papers. Of the 3489 articles identified, 30 met inclusion criteria and were reviewed. Much research to date has focused on the use of printed material and person-based discharge communication methods including verbal instructions (either in person or via telephone calls). Several studies have examined the use of information technology (IT) such as computer-generated and video-based discharge communication practices. Utilizing technology to deliver discharge information is preferred by healthcare providers and patients, and improves patients' understanding of their medical condition and discharge instructions. Well-designed IT solutions may improve communication, coordination and retention of information, and lead to improved outcomes for patients, their families, caregivers and primary healthcare providers as well as expediting the task for hospital staff.

The best location in the inner solar system for the grand observatories of the 21st century may be the moon. A multidisciplinary team including university students and faculty in engineering, astronomy, physics, and geology, and engineers from industry is investigating the moon as a site for astronomical observatories and is doing conceptual and preliminary designs for these future observatories. Studies encompass lunar facilities for radio astronomy and astronomy at optical, ultraviolet, and infrared wavelengths of the electromagnetic spectrum. Although there are significant engineering challenges in design and construction on the moon, the rewards for astronomy can be great, such as detection and study of earth-like planets orbiting nearby stars, and the task for engineers promises to stimulate advances in analysis and design, materials and structures, automation and robotics, foundations, and controls. Fabricating structures in the reduced-gravity environment of the moon will be easier than in the zero-gravity environment of earth orbit, as Apollo and space-shuttle missions have revealed. Construction of observatories on the moon can be adapted from techniques developed on the earth, with the advantage that the moon's weaker gravitational pull makes it possible to build larger devices than are practical on earth.

Occupational injuries are an important source of morbidity for emergency medical services (EMS) providers. Previous work has shown that employee perceptions of an organization's commitment to safety (i.e., safety climate) correlate with adherence to safe practices. To assess the association between perceived safety climate and compliance with safety procedures in an urban EMS system with >100,000 calls/year. EMS providers were issued a self-administered survey that included questions on demographics, years of experience, perceived safety climate, and adherence to safety procedures. Safety climate was assessed with a 20-item validated instrument. Adherence to safety procedures was assessed with a nine-item list of safety behaviors. Strict adherence to safety procedures was defined as endorsing "agree" or "strongly agree" on 80% of items. The effect of safety climate on compliance with safe practices was estimated using multiple logistic regression. One hundred ninety-six of 221 providers (89%) completed surveys; 74% were male; the median age was 36-40 years; and the median amount of experience was 8 years. One hundred twenty-seven of 196 respondents (65%) reported strict adherence to safe work practice. Factor analysis confirmed the original six-factor grouping of questions; frequent safety-related feedback/training was significantly associated with safe practices (odds ratio [OR] = 2.14, 95% confidence interval [CI] = 1.01-4.51). EMS workers perceiving a high degree of perceived safety climate was associated with twofold greater odds of self-reported level of strict adherence to safe work practices. Frequent safety-related feedback/training was the one dimension of safety climate that had the strongest association with adherence to safe workplace behaviors.

More than 35 000 umbilical cord blood (UCB) transplants have been performed worldwide, prompting the development of private and public banks to collect and store UCB cells. We hypothesized that pediatricians, who are uniquely poised to discuss UCB banking (UCBB) during prenatal or sibling visits, rarely do so. Through distribution of a 26-question electronic survey to general and subspecialty pediatric providers, we assessed baseline knowledge and conversations about UCBB. A total of 473 providers completed the survey; only 22% of physicians ever discussed UCBB with expectant parents. The majority responded that autologous UCB transplants were indicated in malignant (73%) and nonmalignant (61%) conditions; however, these are rare indications. Providers practicing >10 years were more likely to address UCBB ( P ≤ .001), whereas younger and female general pediatric providers were significantly less likely ( P < .001). Overall, pediatric providers rarely speak to families about UCBB, and we believe that they can be better informed to its current clinical utility.

In this article, we consider the conduct of post-apartheid health care in a policy context directed toward entrenching democracy, ensuring treatment-adherent patients, and creating a healthy populace actively responsible for their own health. We ask how tuberculosis treatment, antiretroviral therapy, and maternal services are delivered within South Africa's health system, an institutional site of colonial and apartheid injustice, and democratic reform. Using Foucauldian and post-Foucauldian notions of governmentality, we explore provider ways of doing to, for, and with patients in three health subdistricts. Although restorative provider engagements are expected in policy, older authoritarian and paternalistic norms persist in practice. These challenge and reshape, even 'undo' democratic assertions of citizenship, while producing compliant, self-responsible patients. Alongside the need to address pervasive structural barriers to health care, a restorative approach requires community participation, provider accountability, and a health system that does with providers as much as providers who do with patients.

There are limited data on lesbian, gay, bisexual, and transgender (LGBT) healthcare experiences and interactions with the providers. This study assessed knowledge, attitudes, and practice behaviors of oncology providers regarding LGBT health. A 32-item web-based survey was emailed to 388 oncology providers at a single institution. The survey assessed: demographics, knowledge, attitudes, and practice behaviors. 108 providers participated in the survey (28% response rate). LGBT cultural competency at the institution. Results from the open comments section identified multiple misconceptions. This study revealed knowledge gaps about LGBT health risks. Cultural competency training may aid oncology providers to understand the need to inquire about patients' gender identity and sexual orientation. Health care providers who incorporate the routine collection of gender identity and sexual orientation (SOGI) in their patient history taking may improve patient care by offering tailored education and referrals. While identifying as LGBT does not in itself increase risk for adverse health outcomes, this population tends to have increased risk behaviors. Copyright © 2016 Elsevier Ireland Ltd.

Pain syndromes are common in HIV-infected patients, who also are commonly affected by opioid-use disorders. Although opioids can treat pain, prescribers must consider the consequences of iatrogenic or missed addiction diagnoses. In an anonymous online survey, we asked a national sample of HIV providers about their demographics, experience, and patients, and their practices and attitudes about chronic opioid therapy, addiction, and confidence recognizing opioid analgesic abuse. One hundred six providers reported 28% of their patients had chronic pain; 21% received opioid analgesics; 37% were HIV infected by injecting drug use; and 12% were addicted to prescription opioids. Few providers followed recommended guidelines for chronic opioid therapy in nonmalignant pain. Mean provider confidence was 6.3 on a scale of 10. Higher confidence was associated with provider sex (P opioids (P = 0.005), and prescribing buprenorphine (P = 0.009). HIV providers seldom follow recommended guidelines for opioid prescribing and have limited confidence in their ability to recognize opioid analgesic abuse. Clinical practices developed to reduce misuse and increase early detection and treatment of opioid dependence are associated with higher confidence. The implementation of guidelines to improve the quality of opioid prescribing in HIV clinics may aid in the diagnosis of addictive disorders and prevent their adverse outcomes.

Sleep disorders significantly affect the lives of children with epilepsy. Limited data exist about provider practices concerning detection and correct diagnosis of sleep problems in epilepsy. The authors conducted this study to identify and correlate sleep screening methods, referral practices, referral reasons and final sleep diagnoses. They identified that 94% of the providers who had referred patients to the sleep center of a major children's hospital used routine screening and 70% of them used 2 to 3 screening questions. This method, however, underidentified the patients at risk for sleep disorders. Moreover, in 40% of the children, sleep disorder was incorrectly anticipated, based on the initial symptoms. Of these children, 10% had no sleep disorder and 30% had unexpected sleep disorder. The authors conclude that better screening methods should be used for sleep disorders. Once identified, these patients should have formal sleep evaluation and management. Further studies are needed to develop screening questionnaires.

BRAC (formerly Bangladesh Rural Advancement Committee), in collaboration with the National Tuberculosis Control Programme, provides one full-day training on TB to make informal allopathic providers knowledgeable for managing TB in rural Bangladesh. This study explored the knowledge and practices of the providers receiving the above training in the control and prevention of TB. The study was conducted in 30 subdistricts, with 30 trained and 30 untrained providers randomly selected from each subdistrict. Approximately 3% (49/1800) did not provide complete information. Pre-tested structured and semi-structured questionnaires were used. TB was commonly perceived as a disease of only males (66.1%, 1157/1751). Only one-quarter knew about the bacterial cause of TB. Very few providers (2.1%, 36) had adequate knowledge regarding prevention of TB. They also lacked knowledge about TB treatment duration (71.6%, 1253), the meaning of DOTS (directly observed treatment, short course) (26.0%, 455) and multidrug resistance (20.6%, 360). Antibiotics (79.7%, 1396) and cough syrup (75.0%, 1313) were commonly prescribed by providers despite symptoms suggestive of TB. However, 70.2% (613) and 74.5% (650) of trained providers' knowledge and practice scores were equal to or more than the mean scores (≥6.97 and ≥6.6, respectively), whereas they were only 49.5% (435) and 64.2% (563), respectively, among untrained providers (ppreventing TB efficiently. © The Author 2014.

The Tanzanian health sector suffers from shortages of healthcare workers as well as uneven distribution of healthcare workers in urban and rural areas. Task shifting-delegation of tasks from professionals to other healthcare team members with less training, such as medical attendants-is practiced, compromising quality of care. Advanced practice nursing is underutilized. The purpose of this study was to explore the views of nurses and physicians on current responses to shortages of healthcare workers and the potential for utilization of advanced practice nurses. A descriptive, qualitative design was used. Purposeful sampling was used to select 20 participants. An in-depth interview guide was used to obtain information. Interviews were conducted in Swahili or English. Content analysis was used to identify themes. Shortage of human resources in rural primary healthcare facilities was identified as a major rationale for implementation of the advanced practice nurse practitioner role because the current health providers in rural health facilities are less trained and doctors are not ready to work in these settings. Opposition from physicians is expected during the course of implementing the nurse practitioner role. Professional bodies and government should reach consensus before the implementation of this role in such a way that they should agree on scope and standards of practice of nurse practitioners in Tanzania. Shortage of human resources for health is greater in rural primary healthcare facilities. Task shifting in Tanzania is neither effective nor legally recognized. Transition to advanced practice nursing roles-particularly the nurse practitioner role-can facilitate provision of optimal care. Nurse practitioners should be prepared to work in rural primary healthcare facilities.

The past decade has seen a significant increase in private sector provision of tuberculosis (TB)care. While patients often seek and select treatment from private providers at significant out-of-pocket expense,treatment outcomes remain largely unknown. To investigate the knowledge, attitudes and practices of private sector TB care providers in high burden countries. Medline, PubMed, Embase, International Pharmaceutical Abstracts and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases were searched using Medical Subject Headings terms,Emtree terms and key words. Searches were limited to the English language and published between 1998 and week 2 of November 2009. Studies were included if they reported the knowledge, attitudes or practice behaviours of private health care providers working in one of 22 high-TB-burden countries. Each included study was critically assessed using a structured data extraction tool. Data extracted included the study setting, objective, design, sample, response rate, outcomes and limitations. The 34 studies that met review inclusion criteriaen compassed diverse study methods and designs.All categories of TB care providers lacked comprehensive knowledge of national treatment guidelines. Procedures for referral, treatment monitoring, record keeping and case holding were not systematically implemented.However, there was a high degree of willingness to collaborate with national TB programmes. Research using standardised data collection methods may assist in identifying gaps in knowledge and practice among all providers of TB care. Further studies in developing and evaluating needs-based interventions should be undertaken; systematic reviews of such studies may then assist in strategic decision making in public-private mix DOTS expansion.

Health checks identify (risk factors for) disease in people without symptoms. They may be offered by the government through population screenings and by other providers to individual users as 'personal health checks'. Health check providers' perspective of 'good' health checks may further the debate on the ethical evaluation and possible regulation of these personal health checks. In 2015, we interviewed twenty Dutch health check providers on criteria for 'good' health checks, and the role these criteria play in their practices. Providers unanimously formulate a number of minimal criteria: Checks must focus on (risk factors for) treatable/preventable disease; Tests must be reliable and clinically valid; Participation must be informed and voluntary; Checks should provide more benefits than harms; Governmental screenings should be cost-effective. Aspirational criteria mentioned were: Follow-up care should be provided; Providers should be skilled and experienced professionals that put the benefit of (potential) users first; Providers should take time and attention. Some criteria were contested: People should be free to test on any (risk factor for) disease; Health checks should only be performed in people at high risk for disease that are likely to implement health advice; Follow up care of privately funded tests should not drain on collective resources. Providers do not always fulfil their own criteria. Their reasons reveal conflicts between criteria, conflicts between criteria and other ethical values, and point to components in the (Dutch) organisation of health care that hinder an ethical provision of health checks. Moreover, providers consider informed consent a criterion that is hard to establish in practice. According to providers, personal health checks should meet the same criteria as population screenings, with the exception of cost-effectiveness. Providers do not always fulfil their own criteria. Results indicate that in thinking about the ethics of health

The four screen-fold hieroglyphic books of the Precolumbian Maya that have survived into modern times, known collectively as the Maya codices, provide the most detailed information about the astronomical knowledge and practices that can be attributed to this New World civilization. Four explicitly dated documents in the Dresden Codex treat the cyclical movements of Venus and Mars and both solar and lunar eclipses during several centuries of the Maya Classic and Postclassic, primarily the 8 th through the 14th centuries. In addition, these documents deal with the effects on peoples' lives that were considered to result from these celestial phenomena. A heavily damaged document in the Paris Codex provides information about the Precolumbian Maya view of zodiacal constellations. The lecturers will explain what is in these astronomical records and discuss some of the techniques used to understand them.

There are an estimated 3.5 million Muslims in North America. During the holy month of Ramadan, healthy adult Muslims are to fast from predawn to after sunset. While there are exemptions for older and sick adults, many adults with diabetes fast during Ramadan. However, there are risks associated with fasting and specific management considerations for patients with diabetes. We evaluated provider practices and knowledge regarding the management of patients with diabetes who fast during Ramadan. A 15-question quality improvement survey based on a literature review and the American Diabetes Association guidelines was developed and offered to providers at the outpatient primary care and geriatric clinics at an inner-city hospital in New York City. Forty-five providers completed the survey. Most respondents did not ask their Muslim patients with diabetes if they were fasting during the previous Ramadan. Knowledge of fasting practices during Ramadan was variable, and most felt uncomfortable managing patients with diabetes during Ramadan. There is room for improvement in educating providers about specific cultural and medical issues regarding fasting for patients with diabetes during Ramadan. © The Author(s) 2015.

Ground based telescopes are, even in this era of planetary missions and space telescopes, the dominant source of data on solar system objects. Yet many of the premier observing sites in the world are threatened by increasing artificial light that is scattered into the sky - light pollution. World class observing sites such as Mt. Wilson have long since lost the ability to do cutting edge faint object science and observatories in Southern Arizona have been recently threatened - the Canoa Ranch development being the most recent example. Yet there are actions that can be taken to preserve dark skies, not only for astronomy, but also for the benefit of all humanity. Lead by astronomers, effective outdoor lighting codes have been produced and adopted by many jurisdictional authorities. Advocacy organizations such as the International Dark-sky Association (IDA) distribute educational material on how to preserve dark skies through good outdoor lighting practices. Other institutions, such as the National Park Service, are realizing that dark skies are an integral part of the wilderness experience and are taking steps to preserve the quality of their skies. However, the primary beneficaries of dark sky preservation efforts, namely the ground based astronomical community, have largely failed to become involved in efforts to preserve dark skies. For example, only a few percent of the membership of the American Astronomical Society is active in light pollution work or is even a member of IDA. In this presentation, Iwe will outline what is being done locally to preserve dark skies througout the world. In addition, some observations on the level of support from the astronomical community will be offered.

The present article refers to a qualitative study that was performed with the objective to identify and analyze the practice of healthcare professionals regarding rural women victims of violence, under the perspective of comprehensive care, in cities located in southern Rio Grande do Sul state. Participants were healthcare professionals and workers from health services who work in rural areas. The information was generated through interviews and analyzed using the thematic mode. In regards to care elements provided to rural women who are victims of violence, the study pointed out not only the relational strategies - welcoming, attachment and dialogue - but also the construction of collective actions through group activities, recognized as supporting health promotion, as well as individual and collective empowerment in the dimension of violent events. It was found that the professionals' care practices are aimed at focusing care on the rural women, establishing a relationship between the worker and client to produce comprehensiveness of care.

Full Text Available Abstract Background There is a need for assistance from primary care mental health workers in general practice in the Netherlands. General practitioners (GPs experience an overload of frequent attenders suffering from psychological problems. Problem Solving Treatment (PST is a brief psychological treatment tailored for use in a primary care setting. PST is provided by nurses, and earlier research has shown that it is a treatment at least as effective as usual care. However, research outcomes are not totally satisfying. This protocol describes a randomized clinical trial on the effectiveness of PST provided by nurses for patients in general practice. The results of this study, which currently being carried out, will be presented as soon as they are available. Methods/design This study protocol describes the design of a randomized controlled trial to investigate the effectiveness and cost-effectiveness of PST and usual care compared to usual care only. Patients, 18 years and older, who present psychological problems and are frequent attenders in general practice are recruited by the research assistant. The participants receive questionnaires at baseline, after the intervention, and again after 3 months and 9 months. Primary outcome is the reduction of symptoms, and other outcomes measured are improvement in problem solving skills, psychological and physical well being, daily functioning, social support, coping styles, problem evaluation and health care utilization. Discussion Our results may either confirm that PST in primary care is an effective way of dealing with emotional disorders and a promising addition to the primary care in the UK and USA, or may question this assumption. This trial will allow an evaluation of the effects of PST in practical circumstances and in a rather heterogeneous group of primary care patients. This study delivers scientific support for this use and therefore indications for optimal treatment and referral.
During disasters, clinicians may be forced to play dual roles, as both a provider and an allocator of scarce resources. At present, a clear framework to govern resource stewardship at the bedside is lacking. Clinicians who find themselves practicing in this ethical gap between clinical and public health ethics can experience significant moral distress. One provider describes her experience allocating an oxygen tank in the intensive care unit at a hospital in Port-au-Prince, Haiti, immediately following the 2010 earthquake. Using a clinical vignette and reflective narrative she attempts to identify the factors that influenced her allocation decision, opening up the factors for commentary and debate by an ethicist. A better paradigm for the ethical care of patients during disasters is needed to better guide provider choices in the future.
The capability of small aperture astronomical instrumentation systems (AIS) to make meaningful scientific contributions has never been better. The purpose of AIS quality management planning (AISQMP) is to ensure the quality of these contributions such that they are both valid and reliable. The first step involved with AISQMP is to specify objective quality measures not just for the AIS final product, but also for the instrumentation used in its production. The next step is to set up a process to track these measures and control for any unwanted variation. The final step is continual effort applied to reducing variation and obtaining measured values near optimal theoretical performance. This paper provides an overview of AISQMP while focusing on objective quality measures applied to astronomical imaging systems.

Full Text Available A growing number of Internet sites and mobile applications are being developed intended for use in clinical practice. However, during the development process (e.g., creating features and determining use cases, the needs and interests of providers are often overlooked. We explored providers' interests using a mixed-methods approach incorporating both qualitative and quantitative research methods. A first study used an interview approach to identify the challenges providers faced, tools they used, and any use of computers and apps specifically. Fifteen providers from both the United States and Canada completed the interview and recordings were transcribed and analyzed using a constructivist grounded theory approach. Four primary themes were identified including challenges, potential tools, access and usability. A second study used a brief survey completed by 132 providers at a large healthcare system to explore current use of and potential interest in Internet and mobile technologies. Although many providers (80.9% reported recommending some form of technology to patients, these were mostly Internet websites that were predominantly informational/psychoeducational in nature. Overall, these studies combine to suggest a strong interest in websites and apps for use in clinical settings while highlighting potential areas (ease of use, patient security and privacy that should be considered in the design and deployment of these tools.

Provider-patient relations may influence the nature of care provided. The aim of this study was to examine dentist preferences for patients, relate these to characteristics of dentists and practices, and to services provided. A random sample of Australian dentists completed mailed questionnaires (response = 60.3%). Four factor-based subscales and an overall scale (Selectivity) were derived from a 37-item battery. The 4 subscales comprised treatment adherence (behavior relevant to the treatment situation), personal adaptability (willingness to cooperate when expected to do so), social interactiveness (positive affect, communicativeness, and appreciativeness), and enabling characteristics (willing and able to pay, and good dental knowledge). Reliability was adequate (Cronbach's alpha = 0.71-0.90). Treatment adherence was associated with higher orthodontic rates, but a lower extraction rate; social interactiveness was associated with higher extraction and denture rates; personal adaptability was associated with higher orthodontic rates, but lower general/miscellaneous service rates; enabling characteristics was associated with higher endodontic and crown and bridge rates; selectivity was associated with higher rates of diagnostic, preventive, and total services per visit. The associations with service rates indicated that provider preferences were related to treatment behavior that could affect the mix of services, indicating that the nature of care provided may be influenced by the provider-patient relation.

Concussion is an emerging public health concern, but care of patients with a concussion is presently unregulated in Canada. Independent, blinded Google Internet searches were conducted for the terms "concussion" and "concussion clinic" and each of the Canadian provinces and territories. The first 10 to 15 concussion healthcare providers per province were identified. A critical appraisal of healthcare personnel and services offered on the provider's Web site was conducted. Fifty-eight concussion healthcare providers were identified using this search methodology. Only 40% listed the presence of an on-site medical doctor (M.D.) as a member of the clinical team. Forty-seven percent of concussion healthcare providers advertised access to a concussion clinic, program, or center on their Web site. Professionals designated as team leaders, directors, or presidents among concussion clinics, programs, and centers included a neuropsychologist (15%), sports medicine physician (7%), neurologist (4%), and neurosurgeon (4%). Services offered by providers included baseline testing (67%), physiotherapy (50%), and hyperbaric oxygen therapy (2%). This study indicates that there are numerous concussion healthcare providers in Canada offering diverse services with clinics operated by professionals with varying levels of training in traumatic brain injury. In some cases, the practices of these concussion clinics do not conform to current expert consensus guidelines.

Almost half of all pregnancies in the United States are unintended; these pregnancies are associated with adverse outcomes. Many reproductive-age females seek care in the emergency department (ED), are at risk of pregnancy, and are amenable to contraceptive services in this setting. Through a pilot study, we sought to assess ED providers' current practices; attitudes; and knowledge of emergency contraception (EC) and nonemergency contraception (non-EC), as well as barriers with respect to contraception initiation. ED physicians and associate providers in Georgia were e-mailed a link to an anonymous Internet questionnaire using state professional databases and contacts. The questionnaire included Likert scales with multiple-choice questions to assess study objectives. Descriptive statistics were generated as well as univariate analyses using χ(2) and Fisher exact tests. A total of 1232 providers were e-mailed, with 119 questionnaires completed. Participants were predominantly physicians (80%), men (59%), and individuals younger than 45 years (59%). Common practices were referrals (96%), EC prescriptions (77%), and non-EC prescriptions (40%). Common barriers were perceived as low likelihood for follow-up (63%), risk of complications (58%), and adverse effects (51%). More than 70% of participants correctly identified the highly effective contraceptive methods, 3% identified the correct maximum EC initiation time, and 42% correctly recognized pregnancy as a higher risk than hormonal contraception use for pulmonary embolism. Most ED providers in this pilot study referred patients for contraception; however, there was no universal contraceptive counseling and management. Many ED providers in this study had an incorrect understanding of the efficacy, risks, and eligibility associated with contraceptive methods. This lack of understanding may affect patient access and be a barrier to patient care.

A cluster-randomized design was proposed to compare treatment strategies by assigning clusters (eg, providers to “favor” a particular drug, with providers retaining autonomy for specific patients. Patient informed consent might be waived, broadening inclusion. However, it is not known if providers will adhere to the assignment or whether institutional review boards will waive consent. We evaluated the feasibility of this trial design.Subjects and methods: Agreeable providers were randomized to “favor” either hydrochlorothiazide or chlorthalidone when starting patients on thiazide-type therapy for hypertension. The assignment applied when the provider had already decided to start a thiazide, and providers could deviate from the strategy as needed. Prescriptions were aggregated to produce a provider strategy-adherence rate.Results: All four institutional review boards waived documentation of patient consent. Providers (n=18 followed their assigned strategy for most of their new thiazide prescriptions (n=138 patients. In the “favor hydrochlorothiazide” group, there was 99% adherence to that strategy. In the “favor chlorthalidone” group, chlorthalidone comprised 77% of new thiazide starts, up from 1% in the pre-study period. When the assigned strategy was followed, dosing in the recommended range was 48% for hydrochlorothiazide (25–50 mg/day and 100% for chlorthalidone (12.5–25.0 mg/day. Providers were motivated to participate by a desire to contribute to a comparative effectiveness study. A study promotional mug, provider information

This study aimed to determine the current attitudes, perceptions, and practices of emergency medicine providers and nurses (RNs) regarding the discharge of adult patients from the emergency department (ED) after administration of opioid analgesics. A cross-sectional survey was administered at 3 hospital sites with a combined annual ED census of >180,000 visits per year. All 59 attending emergency physicians (EPs), 233 RNs, and 23 advanced practice clinicians (APCs) who worked at these sites were eligible to participate. Thirty-five EPs (59.3%), 88 RNs (37.8%), and 14 APCs (60.9%) completed the survey for an overall response rate of 51.75%. Most respondents were female (95 [69.9%]). The factor ranked most important to consider when discharging a patient from the ED after administration of opioids was the patient's functional status and vital signs (median, 2.00; interquartile range, 2.00-3.50). More RNs (84 [96.6%]) than EPs (29 [82.9%]) reported that developing an ED policy or guideline for safe discharge after administration of opioids is important to clinical practice (P = 0.02). Only 8 physicians (23.5%) reported that they did not prescribe intramuscular morphine, and 15 (42.9%) reported that they did not prescribe intramuscular hydromorphone. EPs (7 [20.0%]) and RNs (3 [3.4%]) differed in regard to whether they were aware if any patients to whom they administered an opioid had experienced an adverse drug-related event (P = 0.01). Most EPs (24 [68.6%]) and RNs (54 [61.4%]) believed that the decision for patient discharge should be left to both the emergency medicine provider and the RN. Most study participants believed that developing a policy or guideline for safe discharge after administration opioids in the ED is important to clinical practice. Only a few physicians reported that they did not prescribe intramuscular hydromorphone or morphine. Most participants believed the discharge decision after administration of opioids in the ED should be primarily
Full Text Available Abstract Background Globally, the monitoring of prompt and effective treatment for malaria with artemisinin combination therapy (ACT is conducted largely through household surveys. This measure; however, provides no information on case management processes at the health facility level. The aim of this review was to assess evidence from health facility surveys on malaria prescribing practices using ACT, in the presence and absence of ACT stock, at time and place where treatment was sought. Methods A systematic search of published literature was conducted. Findings were collated and data extracted on proportion of patients prescribed ACT and alternative anti-malarials in the presence and absence of ACT stock. Results Of the 14 studies identified in which ACT prescription for uncomplicated malaria in the public sector was evaluated, just six, from three countries (Kenya, Uganda and Zambia, reported this in the context of ACT stock. Comparing facilities with ACT stock to facilities without stock (i ACT prescribing was significantly higher in all six studies, increasing by a range of 21.3% in children Conclusions Prescriber practices vary based on ACT availability. Although ACT prescriptions increased and alternative anti-malarials prescriptions decreased in the presence of ACT stock, ACT was prescribed in the absence, and alternative anti-malarials were prescribed in the presence of, ACT. Presence of stock alone does not ensure that treatment guidelines are followed. More health facility surveys, together with qualitative research, are needed to understand the role of ACT stock-outs on provider prescribing behaviours and preferences.

Health and social care professionals increasingly use narrative approaches to focus on the patient and to communicate with each other. Both effective interprofessional education (IPE) and practice (IPP) require recognizing the various values and voices of different professions, how they relate to the patient's life story, and how they interact with each other at the level of the healthcare team. This article analyzes and integrates the literature on narrative to explore: self-narrative as an expression of one's professional identity; the co-creation of the patient's narrative by the professional and the patient; and the interprofessional multi-vocal narrative discourse as co-constructed by members of the healthcare team. Using a narrative approach to thinking about professional identity, provider-patient communication, and interprofessional teamwork expands our thinking about both IPE and IPP by providing new insights into the nature of professional practice based on relationships to oneself, the patient, and others on the team. How professionals define themselves, gather and present information from the patient, and communicate as members of a clinical team all have important dimensions that can be revealed by a narrative approach. Implications and conclusions for the further development of the narrative approach in IPE and IPP are offered.
The Pro-Am Collaborative Astronomy (PACA) project evolved from the observational campaign of C/2012 S1 or C/ISON. The success of the paradigm shift in scientific research is now implemented in other comet observing campaigns. While PACA identifies a consistent collaborative approach to pro-am collaborations, given the volume of data generated for each campaign, new ways of rapid data analysis, mining access, and storage are needed. Several interesting results emerged from the synergistic inclusion of both social media and amateur astronomers: - the establishment of a network of astronomers and related professionals that can be galvanized into action on short notice to support observing campaigns; - assist in various science investigations pertinent to the campaign; - provide an alert-sounding mechanism should the need arise; - immediate outreach and dissemination of results via our media/blogger members; - provide a forum for discussions between the imagers and modelers to help strategize the observing campaign for maximum benefit. In 2014, two new comet observing campaigns involving pro-am collaborations have been identified: (1) C/2013 A1 (C/Siding Spring) and (2) 67P/Churyumov-Gerasimenko (CG). The evolving need for individual customized observing campaigns has been incorporated into the evolution of PACA (Pro-Am Collaborative Astronomy) portal that currently is focused on comets: from supporting observing campaigns for current comets, legacy data, historical comets; interconnected with social media and a set of shareable documents addressing observational strategies; consistent standards for data; data access, use, and storage, to align with the needs of professional observers. The integration of science, observations by professional and amateur astronomers, and various social media provides a dynamic and evolving collaborative partnership between professional and amateur astronomers.

Dual-practice, simultaneous employment by healthcare workers in the public and private sectors is pervasive worldwide. Although an estimated 30 per cent of the global burden of disease is surgical, the implications of dual practice on surgical care are not well understood. Anonymous in-depth individual interviews on trauma quality improvement practices were conducted with healthcare providers who participate in the care of the injured at ten large hospitals in Peru's capital city, Lima. A grounded theory approach to qualitative data analysis was employed to identify salient themes. Fifty interviews were conducted. A group of themes that emerged related to the perceived negative and positive impacts of dual practice on the quality of surgical care. Participants asserted that the majority of physicians in Lima working in the public sector also worked in the private sector. Dual practice has negative impacts on physicians' time, quality of care in the public sector, and surgical education. Dual practice positively affects patient care by allowing physicians to acquire management and quality improvement skills, and providing incentives for research and academic productivity. In addition, dual practice provides opportunities for clinical innovations and raises the economic status of the physician. Surgeons in Peru report that dual practice influences patient care negatively by creating time and human resource conflicts. Participants assert that these conflicts widen the gap in quality of care between rich and poor. This practice warrants redirection through national-level regulation of physician schedules and reorganization of public investment in health via physician remuneration. © 2017 BJS Society Ltd Published by John Wiley & Sons Ltd.

Background Rural populations as well as less educated people in the U.S. are less likely to receive colorectal cancer (CRC) screening than people living in urban areas and more educated people. Methods We tested a computer tablet, Patient/Provider Communication Assistant (PPCA), which collected data, educated patients, and printed personalized notes to patients and providers encouraging conversation about CRC screening. Mixed model analyses using a pre-post quasi-experimental design compared patient results during the comparison and intervention periods in 5 rural primary care practices on provider discussion about CRC screening, provider recommendation, and patient intention to be screened. Models including age, education and literacy measures as covariates were examined. Results Providers talked with patients about CRC screening in general, and colonoscopy specifically more frequently after the PPCA than with the comparison group (p values =.04 and .01, respectively). Providers recommended CRC screening more often to patients in the intervention group than to the comparison group (p=.02). Patients planned to be screened and specifically with colonoscopy more frequently following the intervention than in the comparison group (p=.003). There were no interactions between group and any of the covariates. Ninety-five percent of the patients regardless of age or education found the PPCA easy to use. Conclusion Results indicated increased provider discussion and recommendation, and patients' intentions to obtain CRC screening, and in particular colonoscopy, for patients exposed to the intervention, regardless of the patients' age or literacy levels. The PPCA is a promising intervention method that is acceptable to rural patients. PMID:18725831

Dental caries is the most prevalent chronic childhood disease in the United States. Dental caries affects the health of 60-90% of school-aged children worldwide. The prevalence of untreated early childhood dental caries is 19% for children 2-5 years of age in the U.S. Some factors that contribute to the progression of dental caries include socioeconomic status, access to dental care, and lack of anticipatory guidance. The prevalence of dental caries remains highest for children from specific ethnic or racial groups, especially those living in underserved areas where there may be limited access to a dentist. Although researchers have acknowledged the various links between oral health and overall systemic health, oral health care is not usually a component of pediatric primary health care. To address this public health crisis and oral health disparity in children, new collaborative efforts among health professionals is critical for dental disease prevention and optimal oral health. This evaluation study focused on a 10-week interprofessional practice and education (IPE) course on children's oral health involving dental, osteopathic medical, and nurse practitioner students at the University of California, San Francisco. This study's objective was to evaluate changes in knowledge, confidence, attitude, and clinical practice in children's oral health of the students completed the course. Thirty-one students participated in the IPE and completed demographic questionnaires and four questionnaires before and after the IPE course: (1) course content knowledge, (2) confidence, (3) attitudes, and (4) clinical practice. Results showed a statistically significant improvement in the overall knowledge of children's oral health topics, confidence in their ability to provide oral health services, and clinical practice. There was no statistically significant difference in attitude, but there was an upward trend toward positivity. To conclude, this IPE evaluation showed that

With information and scale as central themes, this comprehensive survey explains how to handle real problems in astronomical data analysis using a modern arsenal of powerful techniques. It treats those innovative methods of image, signal, and data processing that are proving to be both effective and widely relevant. The authors are leaders in this rapidly developing field and draw upon decades of experience. They have been playing leading roles in international projects such as the Virtual Observatory and the Grid. The book addresses not only students and professional astronomers and astrophysicists, but also serious amateur astronomers and specialists in earth observation, medical imaging, and data mining. The coverage includes chapters or appendices on: detection and filtering; image compression; multichannel, multiscale, and catalog data analytical methods; wavelets transforms, Picard iteration, and software tools. This second edition of Starck and Murtagh's highly appreciated reference again deals with to...
There is a growing recognition among secondary educators and administrators that students need to have a science education that provides connections between familiar classes like biology, chemistry, and physics. Because of this waxing interest in an integrative approach to the sciences, there is a broader push for school districts to offer classes geared towards the earth sciences, a field that incorporates knowledge and skills gleaned from the three core science subjects. Within the contexts of a regular secondary school day on a traditional schedule (45- to 50-minute long classes), it is challenging to engage students in rigorous field-based learning, critical for students to develop a deeper understanding of geosciences content, without requiring extra time outside of the regular schedule. We suggest instruction using common, manmade features like drainage retention ponds to model good field practices and provide students with the opportunity to calculate basic hydrologic budgets, take pH readings, and, if in an area with seasonal rainfall, make observations regarding soils by way of trenching, and near-surface processes, including mass wasting and the effects of vegetation on geomorphology. Gains in student understanding are discussed by analyzing the difference in test scores between exams provided to the students after they had received only in-class instruction, and after they had received field instruction in addition to the in-class lectures. In an advanced setting, students made measurements regarding ion contents and pollution that allowed the classes to practice lab skills while developing a data set that was analyzed after field work was completed. It is posited that similar fieldwork could be an effective approach at an introductory level in post-secondary institutions.

Valid and reliable instruments to measure and assess cultural competence for oral health care providers are scarce in the literature, and most published scales have been contested due to a lack of item analysis and internal estimates of reliability. The purposes of this study were, first, to develop a standardized instrument to measure dental students' knowledge of diversity, skills in culturally competent patient-centered communication, and use of culture-centered practices in patient care and, second, to provide preliminary validity support for this instrument. The initial instrument used in this study was a thirty-six-item Likert-scale survey entitled the Knowledge, Efficacy, and Practices Instrument for Oral Health Providers (KEPI-OHP). This instrument is an adaption of an initially thirty-three-item version of the Multicultural Awareness, Knowledge, and Skills Scale-Counselor Edition (MAKSS-CE), a scale that assesses factors related to social justice, cultural differences among clients, and cross-cultural client management. After the authors conducted cognitive and expert interviews, focus groups, pilot testing, and item analysis, their initial instrument was reduced to twenty-eight items. The KEPI-OHP was then distributed to 916 dental students (response rate=48.6 percent) across the United States to measure its reliability and assess its validity. Both exploratory and confirmatory factor analyses were conducted to test the scale's validity. The modification of the survey into a sensible instrument with a relatively clear factor structure using factor analysis resulted in twenty items. A scree test suggested three expressive factors, which were retained for rotation. Bentler's comparative fit and Bentler and Bonnett's non-normed indices were 0.95 and 0.92, respectively. A three-factor solution, including efficacy of assessment, knowledge of diversity, and culture-centered practice subscales, comprised of twenty-items was identified. The KEPI-OHP was found to

NITARP provides a forum in which educators conduct authentic astronomical research with guidance from practicing astrophysicists within an interactive professional learning community. As educators learn to conduct astronomical research, they are simultaneously creating educational outreach programs that connect other educators and secondary students to the research process. This means that, at any given time, participants may be learning astronomical content knowledge, field-specific research methodology, computer programs or devising teaching curricula and methods to extend the research experience to others. To support future endeavors, education research methodologies were employed to document the critical junctures where learning might be thwarted (Laurence, Kelley, Becker, Day & Marshall, 2006). These findings benefit the field in general as conducting authentic research is a key initiative in science education. NITARP also fills a unique critical juncture in the astronomical field. While astronomy is often called a gateway science there remains a precipitous drop-off in the number of students or educators who choose to extend their learning beyond planetarium experiences and introductory courses. To provide an invitation into research, and effective support along the way, we asked the question: What supports and cognitive frameworks learners would need to move from observation to research? Our poster will highlight three necessary skill sets: 1) Visualization constructed from multiple sets of data and images to create data driven conclusions; 2) Team research engagement practices, focused on grappling with data that does not have THE answer but rather a series of patterns or comparisons; 3) The use of multiple software programs, trouble shooting and compatibility. Our poster will discuss the teaching challenges and supports we developed to bring students through the research process and widen the gateway to STEM learning. This project was made possible through

Noninvasive prenatal testing (NIPT) through the analysis of cell-free DNA in maternal plasma has rapidly changed screening for fetal chromosome abnormalities. We review practical and ethical challenges associated with the transition, progress in their resolution, and identify new emerging difficulties. NIPT is an advanced screening test for trisomies 21, 18, and 13 that was initially limited to women at high risk for an affected pregnancy. It is now recognized as suitable for all women. The testing has been expanded to include sex chromosome abnormalities and some microdeletion syndromes. Some ethicists are concerned about inclusion of disorders that have less severe phenotypes. Clinical providers have experienced difficulty in maintaining an up-to-date knowledge about the scope of NIPT, differences between tests, who should be offered the testing, performance of tests, reasons for false-positive results, and optimal patient management following positive results. Some of the practical difficulties associated with the introduction can be attributed to this knowledge gap. There remain some important ethical issues associated with NIPT. We believe that the same ethical and legal principles that were considered in the justification of conventional prenatal screening can be used to assess the appropriateness of additional NIPT applications.

This paper is a report of a study conducted to examine the attitudes, beliefs, behavioural intentions and self-reported behaviour of nurses and physicians relating to key immunization behaviours and compare the findings for nurses and physicians. Immunization is an important and effective public health intervention. Understanding immunization providers' attitudes and beliefs toward immunization has the potential to improve educational efforts and lead to behavioural change. A postal survey was conducted with all immunization providers in British Columbia, Canada, in 2005. The survey elicited data on demographics, practice characteristics, attitudes, perceived social norms and perceived behavioural control related to key immunization behaviours. Responses were received from 344 nurses and 349 physicians. The response rate was 67% for nurses and 22% for physicians. More nurses than physicians thought that administering all recommended vaccines at one visit was important (89.2% vs. 63.2%P vaccines (82.4% vs. 48.7%P vaccines at one visit (98.8% vs. 73.8%P vaccine each year was important (88.9%, 87.1% respectively P = 0.65). The foundational work done to develop the survey tool can be used to modify it so that survey findings can be validated according to the Theory of Planned Behaviour. The results could inform the development of behavioural change interventions targeting the identified determinants of immunization provider behaviour.

interactions with physicians (GPs, obstetricians and paediatricians). Midwives with more work experience were more satisfied with their collaboration with GPs. Midwives from the southern region of the Netherlands were more satisfied with collaboration with GPs and obstetricians. Compared to the urban areas, in the rural or mixed areas the midwives were more satisfied regarding their collaboration with MCA(O)s and clinical midwives. Midwives from non-Dutch origin were less satisfied with the collaboration with paediatricians. No relations were found between the overall mean satisfaction of collaboration and work-related and personal characteristics and attitude towards work. Inter-professionals relations in maternity care in the Netherlands can be enhanced, especially the primary care midwives' interactions with physicians and with maternity care providers in the northern and central part of the Netherlands, and in urban areas. Future exploratory or deductive research may provide additional insight in the collaborative practice in everyday work setting. Copyright © 2017 Elsevier Ltd. All rights reserved.

Nutrition is important in the management of chronic disease, and practice nurses in the Australian primary care setting are increasingly providing nutrition care to patients living with chronic disease. The aim of the present study was to investigate practice nurses' perceptions of their role and competency to provide nutrition care to patients living with chronic disease in Australia. Twenty practice nurses currently employed in general practice participated in an individual semi-structured telephone interview. Interviews were transcribed verbatim and thematically analysed. Practice nurses perceived themselves to be in a prime position to provide opportunistic nutrition care to patients. Participants perceived that the ideal role of a practice nurse is to advocate for nutrition and provide a basic level of nutrition care to patients; however, the interpretation of the term 'basic' varied between participants. Participants perceived that practice nurses are highly trusted and approachable, which they valued as important characteristics for the provision of nutrition care. Barriers to providing nutrition care included time constraints, lack of nutrition knowledge and lack of confidence. Participants were concerned about the availability and accessibility of nutrition education opportunities for practice nurses. The present study has demonstrated that practice nurses perceive themselves as having a significant role in the provision of nutrition care to patients with chronic disease in the Australian primary care setting. Further investigation of strategies to enhance the effectiveness of nutrition care provision by practice nurses is warranted.

The USDA food and nutrient databases provide the basic infrastructure for food and nutrition research, nutrition monitoring, policy, and dietary practice. They have had a long history that goes back to 1892 and are unique, as they are the only databases available in the public domain that perform these functions. There are 4 major food and nutrient databases released by the Beltsville Human Nutrition Research Center (BHNRC), part of the USDA's Agricultural Research Service. These include the USDA National Nutrient Database for Standard Reference, the Dietary Supplement Ingredient Database, the Food and Nutrient Database for Dietary Studies, and the USDA Food Patterns Equivalents Database. The users of the databases are diverse and include federal agencies, the food industry, health professionals, restaurants, software application developers, academia and research organizations, international organizations, and foreign governments, among others. Many of these users have partnered with BHNRC to leverage funds and/or scientific expertise to work toward common goals. The use of the databases has increased tremendously in the past few years, especially the breadth of uses. These new uses of the data are bound to increase with the increased availability of technology and public health emphasis on diet-related measures such as sodium and energy reduction. Hence, continued improvement of the databases is important, so that they can better address these challenges and provide reliable and accurate data.
The Phys21 report, ``Preparing Physics Students for 21st Century Careers,'' provides guidance for physics programs to improve their degree programs to make them more relevant for student career choices. Undertaking such changes and assessing impact varies widely by institution, with many departments inventing assessments with each periodic departmental or programmatic review. American Physical Society has embarked on a process to integrate information from Phys21, the results of other national studies, and educational research outcomes to generate a best-practices guide to help physics departments conduct program review, assessment, and improvement. It is anticipated that departments will be able to use this document to help with their role in university-level accreditation, and in making the case for improvements to departmental programs. Accreditation of physics programs could stem from such a document, and I will discuss some of the thinking of the APS Committee on Education in creating this guide, and how they are advising APS to move forward in the higher education landscape that is increasingly subject to standards-based evaluations. I will describe plans for the design, review, and dissemination of this guide, and how faculty can provide input into its development. This material is based upon work supported by the National Science Foundation under Grant No. 1540570. Opinions expressed do not necessarily reflect those of the NSF.
Full Text Available The relationship between Maya and our calendar is expressed by a coefficient known as ‘correlation’ which is a number of days that we have to add to the Mayan Long Count date to get Julian Date used in astronomy. There is surprisingly large uncertainty in the value of the correlation, yielding a shift between both calendars (and thus between the history of Maya and of our world to typically several hundred years. There are more than 50 diverse values of the correlation, some of them derived from historical, other by astronomical data. We test here (among others the well established Goodman-Martínez-Thompson correlation (GMT, based on historical data, and the Böhms’ one (B&B, based on astronomical data decoded from the Dresden Codex (DC; this correlation differs by about +104 years from the GMT. In our previous works we used several astronomical phenomena as recorded in the DC for a check. We clearly demonstrated that (i the GMT was not capable to predict these phenomena that really happened in nature and (ii that the GMT predicts them on the days when they did not occur. The phenomena used till now in the test are, however, short-periodic and the test then may suffer from ambiguity. Therefore, we add long-periodic astronomical phenomena, decoded successfully from the DC, to the testing. These are (i a synchrony of Venusian heliacal risings with the solar eclipses, (ii a synchrony of Venus and Mars conjunctions with the eclipses, (iii conjunctions of Jupiter and Saturn repeated in a rare way, and (iv a synchrony of synodic and sideric periods of Mercury with the tropical year. Based on our analysis, we find that the B&B correlation yields the best agreement with the astronomical phenomena observed by the Maya. Therefore we recommend to reject the GMT and support the B&B correlation.

This study evaluated primary care providers' (PCPs, pediatricians, and nurse practitioners) knowledge, current practices, and perceived barriers to childhood obesity prevention and treatment, with an emphasis on first-year well-child care visits. A questionnaire was distributed to 192 PCPs in the primary care network at The Children's Hospital of Philadelphia (CHOP) addressing (i) knowledge of obesity and American Academy of Pediatrics (AAP) guidelines, (ii) anticipatory guidance practices at well visits regarding nutrition and exercise, and (iii) perceived barriers to childhood obesity treatment and prevention. Eighty pediatricians and seven nurse practitioners responded, and a minority correctly identified the definition (26%) and prevalence (9%) of childhood overweight and AAP guidelines for exercise (39%) and juice consumption (44%). Most PCPs (81%) spent 11-20 min per well visit during the first 2 years, and 79% discussed diet, nutrition, and exercise for > or =3 min. Although >95% of PCPs discussed juice, fruits and vegetables, sippy cups, and finger foods during the first year, over 35% never discussed fast food, TV, or candy, and 55% never discussed exercise. Few rated current resources as adequate to treat or prevent childhood obesity. Over 90% rated the following barriers for obesity prevention and treatment as important or very important: parent is not motivated, child is not motivated, parents are overweight, families often have fast food, watch too much TV, and do not get enough exercise. In conclusion, there is much room to improve PCPs' knowledge of obesity and AAP guidelines. Although PCPs rate fast-food consumption, TV viewing, and lack of exercise as important treatment barriers, many never discussed these topics during the first year.

Pharmacy practice models that foster pharmacists' accountability for medication-related outcomes are imperative for the profession. Comprehensive medication management (CMM) is an opportunity to advance patient care. The objective of this study was to evaluate the impact of a CMM practice model in the acute care setting on organizational, patient, and financial outcomes. Three adult service lines focused on at-risk patients identified using internal risk stratification methodology were implemented. Core CMM elements included medication reconciliation, differentiated clinical pharmacy services, inpatient MTM consultations, discharge services, and documentation. Mixed methods compared the effect of the CMM model before and after implementation. Historical patients served as comparative controls in an observational design. Pharmacists completed a 60-minute interview regarding their experiences. Qualitative data were analyzed using thematic coding to characterize perception of the model. Three pharmacists implemented the model on cardiology, hematology/oncology, and surgery transplant services and provided services to 75 patients during the study. A total of 145 medication-related problems were identified and resolved. CMM was associated with a nonsignificant reduction of 8.8% in 30-day hospital readmission rates ( P = 0.64) and a 24.9% reduction in 30-day hospital utilization ( P = 0.41) as well as a significant reduction of 86.5% in emergency department visits ( P = 0.02). Patients receiving discharge prescriptions from our outpatient pharmacies increased by 21.4%, resulting in an 11.3% increase in discharge prescription capture and additional revenue of $5780. Themes identified from qualitative interviews included CMM structure, challenges, value, and resources. This study demonstrated successful implementation of a CMM model that positively affected organizational, patient, and financial outcomes.
Selected aspects of the participation of the Latin American astronomers in the International Astronomical Union are presented: Membership, Governing bodies, IAU meetings, and other activities. The Union was founded in 1919 with 7 initial member states, soon to be followed by Brazil. In 1921 Mexico joined, and in 1928 Argentina also formed part of the Union, while Chile joined in 1947. In 1961 Argentina, Brazil, Chile, Mexico and Venezuela were already member countries. At present (October 2016) 72 countries contribute financially to the Union. The Union lists 12,391 professional astronomers as individual members; of those, 692 astronomers work in Latin America and the Caribbean, from 13 member states (Argentina, Bolivia , Brazil, Chile, Colombia, Costa Rica, Cuba, Honduras, Mexico, Panamá, Perú, Uruguay and Venezuela) as well as from Ecuador and Puerto Rico. This group comprises 5.58% of the total membership, a figure somewhat lower than the fraction of the population in the region, which is 8.6% of the world population. Of the Latin American members, 23.4% are women and 76.6% are men; slightly higher than the whole membership of Union, which is of 16.9%. In the governing bodies it can be mentioned that there have been 2 Presidents of the Union (Jorge Sahade and Silvia Torres-Peimbert), 7 VicePresidents (Guillermo Haro, Jorge Sahade, Manuel Peimbert Claudio Anguita, Silvia Torres-Peimbert, Beatriz Barbuy, and Marta G. Rovira). The IAU meetings held in the region, include 2 General Assemblies (the 1991 XXI GA took place in Buenos Aires, Argentina and the 2009 XXVIII GA, in Rio de Janeiro, Brazil), 15 Regional Meetings (in Argentina, Brazil, Chile, Colombia, Mexico, Venezuela and Uruguay), 29 Symposia (in Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru and Mexico), 5 Colloquia (in Argentina and Mexico), 8 International Schools for Young Astronomers (in Argentina, Brazil, Cuba, Honduras and Mexico), and 11 projects sponsored by the Office of Astronomy
clearer with ALMA. "Both the detail of the images and the ability to find molecular spectral lines will improve by a factor of at least 25 with ALMA," she said. In addition, the increased power of the EVLA will give astronomers a far better look into the inner regions of the disks around young stars -- regions obscured to telescopes operating at shorter wavelengths. "We know that complex chemicals exist in interstellar space before stars and planets form. With the new research tools coming in the next few years, we're on the verge of learning how the chemistry of the interstellar clouds, the young stars and their environments, and the disks from which planets are formed is all linked together to provide the chemical basis for life on those planets," Remijan explained. Astrophysicist Neil deGrasse Tyson of the American Museum of Natural History noted, "Like no other science, astrophysics cross-pollinates the expertise of chemists, biologists, geologists and physicists, all to discover the past, present, and future of the cosmos -- and our humble place within it."

Learning chemistry is cumulative: basic knowledge and chemical calculation skills are required to gain understanding of higher content. However, we often suffer from students' lack of learning skills to acquire these concepts. One of the reasons is the lack of adequate training in the knowledge and skills of chemistry, and one of the reasons for this lack is the lack of adequate evaluation of training procedures and content. Team-based learning (TBL) is a strong method for providing training in the knowledge and skills of chemistry and reaffirms the knowledge and skills of students of various levels. In our faculty, TBL exercises are provided for first-year students concurrently with lectures in physical chemistry and analytical chemistry. In this study, we researched the adoption of a peer evaluation process for this participatory learning model. Questionnaires taken after TBL exercises in the previous year showed a positive response to TBL. Further, a questionnaire taken after TBL exercises in the spring semester of the current year also yielded a positive response not only to TBL but also to peer evaluation. In addition, a significant correlation was observed between the improvement of students' grades in chemistry classes and the feeling the percentage (20%) of peer evaluation in overall evaluation low (logistic regression analysis, p=0.022). On the basis of the findings, we argue that TBL provides a generic, practical learning environment including an effective focus on learning strategy and evaluation of knowledge, skills, and attitudes, and studies on the educational effects of TBL and peer evaluation.

Tobacco use during pregnancy is substantially higher among Aboriginal women compared to non-Aboriginal women in Australia. However, no studies have investigated the amount or type of smoking cessation care that staff from Aboriginal antenatal and postnatal services provide to clients who smoke or staff confidence to do so. This study examined Aboriginal antenatal and postnatal staff confidence, perceived role and delivery of smoking cessation care to Aboriginal women and characteristics associated with provision of such care. Staff from 11 Aboriginal Maternal and Infant Health Services and eight Aboriginal Child and Family Health services in the Hunter New England Local Health District in Australia completed a cross-sectional self-reported survey (n = 67, response rate = 97.1%). Most staff reported they assessed clients' smoking status most or all of the time (92.2%). However, only a minority reported they offered a quitline referral (42.2%), provided follow-up support (28.6%) or provided nicotine replacement therapy (4.7%) to most or all clients who smoked. Few staff felt confident in motivating clients to quit smoking (19.7%) and advising clients about using nicotine replacement therapy (15.6%). Staff confident with talking to clients about how smoking affected their health had significantly higher odds of offering a quitline referral [OR = 4.9 (1.7-14.5)] and quitting assistance [OR = 3.9 (1.3-11.6)] to clients who smoke. Antenatal and postnatal staff delivery of smoking cessation care to pregnant Aboriginal women or mothers with young Aboriginal children could be improved. Programs that support Aboriginal antenatal and postnatal providers to deliver smoking cessation care to clients are needed. Aboriginal antenatal and postnatal service staff have multiple opportunities to assist Aboriginal women to quit smoking during pregnancy and postpartum. However, staff confidence and practices of offering various forms of smoking cessation support to pregnant Aboriginal

To determine the feasibility of using direct observation of provider-parent immunization discussions and to characterize provider communication practices with vaccine-hesitant parents. Over a 6 month period in 2010, we videotaped immunization discussions between pediatric providers and vaccine-hesitant parents during health supervision visits involving children 2-15 months old (N=24) in the Seattle area, Washington, USA. Videotapes were analyzed using the qualitative method of conversation analysis. We approached 96 parents seen by 9 different providers. Of those who were eligible (N=56), we enrolled 43% (N=24). Four videotaped visits were excluded from analysis for failure to obtain parental HIPAA authorization. Of the remaining 20 visits, there were ≥2 visits each that involved children aged 2, 4, 6, 9, 12, and 15 months, and all videotaped visits contained at least a brief immunization discussion. We identified 6 communication practices and several behavior types within each practice relevant to immunization: Practice 1, providers' initiations of the topic of vaccination; Types: participatory or presumptive format; Practice 2, parents' responses to providers' topic initiations; Types: strong or weak acceptance or resistance; Practice 3, providers' follow-ups to parent's responses; Types: no, immediate, or delayed pursuit; Practice 4, parents' vaccine-related questions or statements; Types: fact- or concern-based; Practice 5, providers' explicit solicitations of parent's questions/concerns; Types: designed to discourage or encourage discussion; and Practice 6, parents' responses to providers' solicitations of questions/concerns; Types: no question or fact- or concern-based inquiry. Direct observation of immunization discussions in the primary care pediatric setting is feasible and yields insight into several provider-parent immunization communication practices that are worthy of further study to determine which are effective at improving parental acceptance of

The Weizmann Fast Astronomical Survey Telescope (W-FAST) is an experiment designed to explore variability on sub-second time scales. When completed it will consist of two robotic 55-cm f/2 Schmidt telescopes. The optics is capable of providing $\\sim0.5$" image quality over 23 deg$^2$. The focal plane will be equipped with fast readout, low read-noise sCMOS detectors. The first generation focal plane is expected to have 6.2 deg$^2$ field of view. WFAST is designed to study occultations by solar system objects (KBOs and Oort cloud objects), short time scale stellar variability, and high resolution imaging via proper coaddition.

Full Text Available Background: Approximately 100,000 persons with sickle cell disease (SCD live in the United States, including 15,000 in the Midwest. Unfortunately, many patients experience poor health outcomes due to limited access to primary care providers (PCPs who are prepared to deliver evidence-based SCD care. Sickle Treatment and Outcomes Research in the Midwest (STORM is a regional network established to improve care and outcomes for individuals with SCD living in Indiana, Illinois, Michigan, Minnesota, Ohio, and Wisconsin. Methods: STORM investigators hypothesized that Project ECHO® methodology could be replicated to create a low-cost, high-impact intervention to train PCPs in evidence-based care for pediatric and young adult patients with SCD in the Midwest, called STORM TeleECHO. This approach utilizes video technology for monthly telementoring clinics consisting of didactic and case-based presentations focused on the National Heart, Lung and Blood Institute (NHLBI evidence-based guidelines for SCD. Results: Network leads in each of the STORM states assisted with developing the curriculum and are recruiting providers for monthly clinics. To assess STORM TeleECHO feasibility and acceptability, monthly attendance and satisfaction data are collected. Changes in self-reported knowledge, comfort, and practice patterns will be compared with pre-participation, and 6 and 12 months after participation. Conclusions: STORM TeleECHO has the potential to increase implementation of the NHLBI evidence-based guidelines, especially increased use of hydroxyurea, resulting in improvements in the quality of care and outcomes for children and young adults with SCD. This model could be replicated in other pediatric chronic illness conditions to improve PCP knowledge and confidence in delivering evidence-based care.

One of the many difficulties a person with dementia can experience is difficulty with way finding and subsequently getting lost in the community. Prescriptions of assistive technology are a key role for occupational therapists. This study aimed to describe the attitudes and practices of occupational therapists in recommending and using assistive technology for persons with dementia who have difficulties with way finding in the community. An online survey was distributed to members of Occupational Therapy Australia NSW and included 25 items on demographics, frequency of use of assistive technology and assessment. A total of 85 occupational therapists responded to the survey. Significant differences were identified in the approaches used, the types of assistive technology used and the evaluation of outcomes, between community-based and hospital-based occupational therapists. Over half of the participants had never prescribed any of the assistive devices listed in the survey for people with dementia. The most frequently prescribed assistive devices were low-tech items that were already freely available to carers and other professions. Therapists used a conservative approach to problem solving with their clients with dementia. There is a limited understanding from occupational therapists about available interventions for people with dementia. Implications for Rehabilitation There is limited awareness on how assistive technology might be used to support occupational performance for persons with dementia. This survey suggests that occupational therapists experience barriers in identifying and providing appropriate assistive technology for this group. Access to targeted education and online resources for occupational therapists is recommended to provide better awareness of the types of assistive technology available to assist persons with dementia and their caregivers.

Full Text Available Objectives: The primary objective of the study is to identify the barriers to providing Introductory Pharmacy Practice Experiences (IPPEs in the hospital setting. Methods: Potential barriers to IPPEs were identified via literature review and interviews with current IPPE preceptors from various institutions. Based on this information, an electronic survey was developed and distributed to IPPE preceptors in order to assess student, preceptor, logistical and college or school of pharmacy related barriers that potentially exist for providing IPPE in the hospital setting. Results: Sixty-eight of the 287 eligible survey respondents (24% completed the electronic survey. Seventy-six percent of respondents agreed or strongly agreed that available time was a barrier to precepting IPPE students even though a majority of respondents reported spending a third or more of their day with an IPPE student when on rotation. Seventy-three percent of respondents disagreed or strongly disagreed that all preceptors have consistent performance expectations for students, while just 46% agreed or strongly agreed that they had adequate training to precept IPPEs. Sixty-five percent of respondents agreed that IPPE students have the ability to be a participant in patient care and 70% of preceptors believe that IPPE students should be involved in patient care. Conclusions: Conducting IPPEs in the institutional setting comes with challenges. Based on the results of this study, experiential directors and colleges/schools of pharmacy could make a positive impact on the quality and consistency of IPPEs by setting student expectations and training preceptors on appropriate and consistent expectations for students.

The Exercise is Medicine Canada (EIMC) initiative promotes physical activity counselling and exercise prescription within health care. The purpose of this study was to evaluate perceptions and practices around physical activity counselling and exercise prescription in health care professionals before and after EIMC training. Prior to and directly following EIMC workshops, 209 participants (physicians (n = 113); allied health professionals (AHPs) (n = 54), including primarily nurses (n = 36) and others; and exercise professionals (EPs) (n = 23), including kinesiologists (n = 16), physiotherapists (n = 5), and personal trainers (n = 2)) from 7 provinces completed self-reflection questionnaires. Compared with AHPs, physicians saw more patients (78% > 15 patients/day vs 93% exercise counselling during routine client encounters (48% vs 72% in most sessions; p exercise counselling into sessions (2.74 ± 0.71, out of 5) compared with AHPs (2.17 ± 0.94; p = 0.001) and EPs (1.43 ± 0.66; p exercise prescription as lack of patient interest (2.77 ± 0.85 out of 4), resources (2.65 ± 0.82 out of 4), and time (2.62 ± 0.71 out of 4). The majority of physicians (85%) provided a written prescription for exercise in exercise routinely, and 33% planned on increasing physical activity and exercise counselling, measured through open-ended responses.

Astronomy and navigation are two sciences whose historical evolution have been linked for centuries through relationships of mutual dependency, up to the point of leading to a new science: astronomical or celestial navigation. Currently, astronomy has a very important well defined area within all university nautical degrees. Knowledge of astronomical navigation is still mandatory for deck officers in merchant ships. In the GPS era, practicing astronomical navigation has been relegated to a mere control procedure, and the tendency is to falling into disuse. Nevertheless, it is still the only method through which seamen can depend on their own means and knowledge to keep a track in a safe way. The new syllabi of our majors contemplates a drastic reduction of the contents of this subject, whose importance in the seafarer's profession we want to highlight in this paper.

Scientific societies provide an important forum for scientists to meet and exchange ideas. In the early days of European settlement in Australia the few people interested in the sciences joined together to form societies that embraced all their individual disciplines. From 1888 the Australasian Association for the Advancement of Science with its different sections allowed a growing number of astronomers to share meetings only with researchers in the closely allied fields of mathematics and physics. Eventually, all three of these groups formed their own societies with the Astronomical Society of Australia (ASA) being the last in 1966. Archival records are used to illustrate how the formation of the ASA came about and to identify the people involved. The makeup of Australian astronomy at that period and some of its research fields are looked at, as well as the debates and discussions in the Society's first year while its future structure and role were established.

This article describes a method to turn astronomical imaging into a random number generator by using the positions of incident cosmic rays and hot pixels to generate bit streams. We subject the resultant bit streams to a battery of standard benchmark statistical tests for randomness and show that these bit streams are statistically the same as a perfect random bit stream. Strategies for improving and building upon this method are outlined.

Relatively few patients receive obesity counselling consistent with the USPSTF guidelines, and many health care professionals (HCPs) are biased in their attitudes towards obesity management. A national sample of family physicians, internists, OB/GYN physicians, and nurse practitioners (NPs) completed a web-based survey of beliefs, practice, and knowledge regarding obesity management. A majority of HCPs believe that it is both the patient's and the provider's responsibility to ensure that the patient is counselled about obesity. Obesity (77%), obesity-related diseases (79%), or obesity-related risk factors (71%) prompt HCPs to offer obesity counselling; 59% of HCPs wait for the patient to broach the subject of their weight. Increased blood pressure (89%) and heart disease risks (90%) are the most common themes in counselling. Across all HCPs except NPs "exercise" is discussed more frequently than "physical activity" (85% vs 81%), "diet" more frequently than "eating habits" (77% vs 75%), and "obesity" more frequently than "unhealthy weight" (60% vs 45%). NPs are more likely to discuss physical activity, eating habits, and unhealthy weight instead. To improve counselling for obesity, HCPs reported needing more time (70%), training in obesity management (53%), improved reimbursement (53%), and better tools to help patients recognise obesity risks (50%). Obesity-related diseases, risk factors, or obesity alone predict obesity counselling amongst HCPs. Better training in weight management and tools to help patients recognise risks appear to be key elements in helping patients compare the risks of what they may consider invasive therapy against the risks of continued obesity.

Teaching hospitals often employ advanced practice providers (nurse practitioners and physician assistants or APPs) to counteract residents' work-hour restrictions. With increased utilization of APPs in labor-intense areas, such as intensive care units (ICUs), APPs may have an impact on resident education and experience. No studies have investigated the direct role an APP plays on the training experience of a surgical resident in the ICU. An institutional review board-approved survey was emailed to residents in Accreditation Council for Graduate Medical Education-accredited general surgery programs. Surveys asked about demographics, residency and/or ICU characteristics, and the effects of APPs on patient care, workflow, and educational experience. Regression analysis determined predictors of resident perception. A total of 354 of 1178 residents responded to the survey (30%). Some residents felt that nurses calling APPs preferentially for patient-care issues interfered with education (17%) and residents' ability to follow patients (12%) and was associated with overall detrimental effects to ICU experience on regression (odds ratio, 3.7; confidence interval, 1.5-9.1). Most residents reported positive effects of APPs, such as reduced resident workload (79.8%), teaching protocols and/or guidelines (60.3%), enhanced patient care (60.3%), and enhanced communication (50.5%). When asked how APPs affected their overall ICU experience, 48.4% reported positive effects, 20.6% reported "no effect," and 31% reported detrimental effects. Only a minority of residents perceived that APPs detract from training, particularly those who felt excluded when nurses preferentially contact APPs with patient-care issues. APPs have the potential to enhance training and ICU experience, as reflected in many of the responses. Strategies to maintain direct nurse and resident communication might preserve residents' perception of the educational value of APPs. Copyright © 2015 Elsevier Inc. All

Amateur astronomers who want to enhance their capabilities to contribute to science need look no farther than this guide to using remote observatories. The contributors cover how to build your own remote observatory as well as the existing infrastructure of commercial networks of remote observatories that are available to the amateur. They provide specific advice on which programs to use based on your project objectives and offer practical project suggestions. Remotely controlled observatories have many advantages—the most obvious that the observer does not have to be physically present to carry out observations. Such an observatory can also be used more fully because its time can be scheduled and usefully shared among several astronomers working on different observing projects. More and more professional-level observatories are open to use by amateurs in this way via the Internet, and more advanced amateur astronomers can even build their own remote observatories for sharing among members of a society ...

A class at a small community college, Central Arizona College, was dedicated to astronomical research. Although hands-on research is usually reserved for professionals or graduate students, and occasionally individual undergraduate seniors, we decided to introduce community college students to science by devoting an entire class to research. Nine students were formed into three closely cooperating teams. The class as a whole decided that all three teams would observe Cepheid stars photometrically using a robotic telescope at the Fairborn Observatory. Speaker-phone conference calls were made to Kenneth E. Kissell for help on Cepheid selection, Michael A. Seeds for instructions on the use of the Phoenix-10 robotic telescope, and Douglas S. Hall for assitance in selecting appropriate comparison and check stars. The students obtained critical references on past observations from Konkoly Observatory via airmail. They spent several long night sessions at our apartment compiling the data, making phase calculations, and creating graphs. Finally, the students wrote up their results for publication in a forthcoming special issue of the international journal on stellar photometry, the IAPPP Communication. We concluded that conducting team research is an excellent way to introduce community college students to science, that a class devoted to cooperation as opposed to competition was refreshing, and that group student conference calls with working astronomers were inspiring. A semester, however, is a rather short time to initiate and complete research projects. The students were Sally Baldwin, Cory Bushnell, Bryan Dehart, Pamela Frantz, Carl Fugate, Mike Grill, Jessica Harger, Klay Lapa, and Diane Wiseman. We are pleased to acknowledge the assistance provided by the astronomers mentioned above, James Stuckey (Campus Dean), and our Union Institute and University doctoral committee members Florence Pittman Matusky, Donald S. Hayes, and Karen S. Grove.

Ring resonators provide a means of filtering specific wavelengths from a waveguide, and optionally dropping the filtered wavelengths into a second waveguide. Both of these features are potentially useful for astronomical instruments. In this paper we focus on their use as notch filters to remove the signal from atmospheric OH emission lines from astronomical spectra, however we also briefly discuss their use as frequency combs for wavelength calibration and as drop filters for Doppler planet searches. We derive the design requirements for ring resonators for OH suppression from theory and finite difference time domain simulations. We find that rings with small radii (0.9), but further optimisation is required to achieve higher Q and deeper notches, with current devices having $Q \\approx 4000$ and $\\approx 10$ dB suppression. The overall prospects for the use of ring resonators in astronomical instruments is promising, provided efficient fibre-chip coupling can be achieved.

Astronomy is being transformed by the vast quantities of data, models, and simulations that are becoming available to astronomers at an ever-accelerating rate. The U.S. Virtual Astronomical Observatory (VAO) has been funded to provide an operational facility that is intended to be a resource for discovery and access of data, and to provide science services that use these data. Over the course of the past year, the VAO has been developing and releasing for community use five science tools: 1) "Iris", for dynamically building and analyzing spectral energy distributions, 2) a web-based data discovery tool that allows astronomers to identify and retrieve catalog, image, and spectral data on sources of interest, 3) a scalable cross-comparison service that allows astronomers to conduct pair-wise positional matches between very large catalogs stored remotely as well as between remote and local catalogs, 4) time series tools that allow astronomers to compute periodograms of the public data held at the NASA Star and Exoplanet Database (NStED) and the Harvard Time Series Center, and 5) A VO-aware release of the Image Reduction and Analysis Facility (IRAF) that provides transparent access to VO-available data collections and is SAMP-enabled, so that IRAF users can easily use tools such as Aladin and Topcat in conjuction with IRAF tasks. Additional VAO services will be built to make it easy for researchers to provide access to their data in VO-compliant ways, to build VO-enabled custom applications in Python, and to respond generally to the growing size and complexity of astronomy data.

Does psychomotor practice affect the student's ability to perform venipuncture? This was the primary question in a study conducted to compare two versions of an instructional program--a no-practice version and a costly version that involved practice on the simulated arm. The initial study was composed of 40 (20 each group) Junior nursing students enrolled in a baccalaureate program. The instructional program for both groups included a handout of the task-by-task description of the procedure; a performance check list, a 10-minute color videotape demonstrating the entire process, and a live demonstration on a simulated arm. Each group took a post test which covered the cognitive aspects of the task. The practice group was able to practice on the simulated arm prior to evaluation on a live subject. The cognitive scores for both groups were near 90% and the performance scores above 80%. Since there was no significant difference between the groups the study was repeated with another group of students from the same school. This group differed slightly from the original group in that they had no experience with venipuncture. The second study contained 34 students and the cognitive scores were 91% for both groups and above 80% for the performance scores. The results indicated that the least costly version was equally effective and presents nursing education with an opportunity to evaluate skills teaching to determine the most effective, efficient and/or economical method to teach skills.

To evaluate methods of performance assessment through an international literature review and a survey of current practice. Over the past two decades health care organizations have focussed on promoting high quality care in conjunction with retaining motivated staff. Cognisant of such initiatives, we sought to evaluate assessment methods for qualified staff according to their utility in the working environment. A systematic literature search was completed and each paper independently reviewed. All health care organizations in Northern Ireland submitted details of their performance assessments. Each was critically appraised using a utility index. Performance was not universally defined. A broad range of assessments were identified, each method had advantages and disadvantages. Although many lacked rigorous testing, areas of good practice were also noted. No single method is appropriate for assessing clinical performance. Rather, this study endorses proposals for a multi-method strategy to ensure that performance assessment demonstrates all attributes required for effective nursing and midwifery practice.

Abstract Optimal pediatric HIV disclosure impacts illness and developmental experiences while improving access to timely treatment. However, disclosure rates in high HIV prevalence countries remain low and there are limited data on best practices. We conducted a qualitative study of disclosure practices and interviewed healthcare providers from five pediatric HIV clinics in Kenya. We identified themes central to disclosure practices, rationale for approaches, barriers to implementing disclosure, and creative strategies to overcome challenges. We used these insights to develop a practice-based framework for disclosure that is sensitive to practical challenges. Overall, providers had limited training but extensive experience in disclosure, endorsed individualized disclosure practices, invested substantial time on disclosure despite clinical burden, and noted adverse outcomes associated with unplanned or abrupt disclosure. Providers advocated for an approach to disclosure that is child-centered but respects caregiver fears and values. Caregiver support was provided to enable caregivers to be the person who ultimately disclosed HIV status to children. Unplanned or abrupt disclosure to children was reported to have severe and persistent adverse impact and was a stimulus to accelerate disclosure in scenarios when providers believed children may be suspecting their diagnosis. Based on these expert insights, the framework we developed incorporates concurrent evaluation of child and caregiver readiness, identifies cues to prompt disclosure discussions, includes caregiver education and support, and utilizes a gradual approach of unveiling HIV diagnosis to the child.

Association of provider opioid prescribing practices and the Centers for Medicare and Medicaid Services hierarchical condition category score: A retrospective examination of correlation between the volume of provider-prescribed opioid medications and provider panel complexity
Full Text Available Objective: Opioids are being prescribed at increasing rates in primary care practices, and among individual providers there is significant variability in opioid prescribing. Primary care practices also vary significantly in complexity of their patients, ranging from healthy patients to those with multiple comorbidities. Our objective was to examine individual primary care providers for an association between their opioid prescribing and the complexity/risk of their panel of patients (a panel of patients is a group of patients whose medical care is the responsibility of a specific healthcare provider or care team. Methods: We retrospectively examined 12 months of opioid prescription data from a primary care practice. We obtained counts of opioids prescribed by providers in the Mayo Clinic, Rochester, Minnesota primary care practice. For patients paneled (assigned to family medicine and internal medicine, we used the Centers for Medicare and Medicaid Services hierarchical condition category patient risk score as a measure of patient complexity. After adjusting the opioid counts for panel patient count (to get opioid counts per patient, we used linear regression analysis to determine the correlation between the hierarchical condition category risk and the amount of opioid prescribed by individual providers. Results: Among our combined 103 primary care providers, opioid unit counts prescribed per patient were highly correlated with the providers’ hierarchical condition category panel risk score (r2 = 0.54. After excluding three outliers, r2 was 0.74. With and without the outliers, the correlation was very significant (p 0.45 showed significant correlation with hierarchical condition category (r2 = 0.26; p = 0.001. Conclusion: When examining differences in primary care providers’ opioid prescribing practices, the Centers for Medicare and Medicaid Services endorsed risk score (the hierarchical condition category score can help

Full Text Available Jamie S Massengill,1 John L Kittredge2 1JSM Medical, Edmond, OK, USA; 2Michiana Spine, Sports and Occupational Rehab, PC, Mishawaka, IN, USA Abstract: An estimated one million individuals in the US are diagnosed with herpes zoster (HZ; shingles each year. Approximately 20% of these patients will develop postherpetic neuralgia (PHN, a complex HZ complication characterized by neuropathic pain isolated to the dermatome that was affected by the HZ virus. PHN is debilitating, altering physical function and quality of life, and commonly affects vulnerable populations, including the elderly and the immunocompromised. Despite the availability of an immunization for HZ prevention and several approved HZ treatments, the incidence of PHN is increasing. Furthermore, management of the neuropathic pain associated with PHN is often suboptimal, and the use of available therapeutics may be complicated by adverse effects and complex, burdensome treatment regimens, as well as by patients' comorbidities and polypharmacy, which may lead to drug–drug interactions. Informed and comprehensive assessments of currently available pharmacological treatment options to achieve effective pain control in the primary care setting are needed.

Evidence-based treatments (EBTs) are "interventions" that have been proven effective through rigorous research methodologies. Evidence-based practice (EBP), however, refers to a "decision-making process" that integrates the best available research, clinician expertise, and client characteristics. This study examined community mental health service…

Immunisation coverage of children by 19 months of age in US primary care practices is below the desired goal of 80%. In order to improve this rate, primary care providers must first understand the specific processes of immunisation delivery within their office settings. This paper aims to identify key components in identifying strategies for quality improvement (QI) of immunisation delivery. We surveyed a South Carolina Pediatric Practice Research Network (SCPPRN) representative for each of six paediatric practices. The surveys included questions regarding immunisation assessment, medical record keeping, opportunities for immunisation administration and prompting. Subsequently, research staff visited the participating practices to directly observe their immunisation delivery process and review patient charts in order to validate survey responses and identify areas for QI. Most survey responses were verified using direct observation of actual practice or chart review. However, observation of actual practice and chart review identified key areas for improvement of immunisation delivery. Although four practices responded that they prompted for needed immunisations at sick visits, only one did so. We also noted considerable variation among and within practices in terms of immunising with all indicated vaccines during sick visits. In addition, most practices had multiple immunisation forms and all administered immunisations were not always recorded on all forms, making it difficult to determine a child's immunisation status. For any QI procedure, including immunisation delivery, providers must first understand how the process within their practice actually occurs. Direct observation of immunisation processes and medical record review enhances survey responses in identifying areas for improvement. This study identified several opportunities that practices can use to improve immunisation delivery, particularly maintaining accurate and easy-to-locate immunisation records

ImgCutout is a Web application that enables professional astronomers and the general public to interactively visualize and explore large, complex astronomical data sets. The application consists of a Web interface that calls a Web service, which accesses SkyServer, a 1 TB SQL Server database containing catalog data for 100 million objects, spectra and images from the Sloan Digital Sky Survey. ImgCutout builds, in real time, color mosaic-images of user-selected regions of the sky, and overlays additional information about astronomical and spatial objects in the database including: boundaries of survey fields and aperture plates, outlines of individual objects and data quality masks, in addition to locations of photometric and spectroscopic objects. The tool can search for lists of known objects, allows new database queries, and provides detailed information about selected objects.
This book on astronomical measurement takes a fresh approach to teaching the subject. After discussing some general principles, it follows the chain of measurement through atmosphere, imaging, detection, spectroscopy, timing, and hypothesis testing. The various wavelength regimes are covered in each section, emphasising what is the same, and what is different. The author concentrates on the physics of detection and the principles of measurement, aiming to make this logically coherent. The book is based on a short self contained lecture course for advanced undergraduate students developed and taught by the author over several years.
Modern astronomical surveys yield massive catalogs of noisy high-dimensional objects, e.g., images, spectra, and light curves. Valuable information stored in individual objects can be lost when ad hoc approaches of feature extraction are used in an effort to build data sets amenable to established data analysis tools. Deep learning procedures provide a promising avenue to enabling the use of data in their raw form and hence allowing both for estimates of greater accuracy and for novel discoveries with greater confidence. This talk will give an overview of deep learning and its potential in astronomical applications.

Integration of pharmacists into primary care general practice clinics has the potential to improve interdisciplinary teamwork and patient care; however this practice is not widespread. The aim of this study was to review the effectiveness of clinical pharmacist services delivered in primary care general practice clinics. A systematic review of English language randomized controlled trials cited in the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and International Pharmaceutical Abstracts was conducted. Studies were included if pharmacists had a regular and ongoing relationship with the clinic; delivered an intervention aimed at optimizing prescribing for, and/or medication use by, clinic patients; and were physically present within the clinic for all or part of the intervention, or for communication with staff. The search generated 1484 articles. After removal of duplicates and screening of titles and abstracts against inclusion criteria, 131 articles remained. A total of 38 studies were included in the review and assessed for quality. Seventeen studies had common endpoints (blood pressure, glycosylated hemoglobin, cholesterol and/or Framingham risk score) and were included in meta-analyses. Twenty-nine of the 38 studies recruited patients with specific medical conditions, most commonly cardiovascular disease (15 studies) and/or diabetes (9 studies). The remaining 9 studies recruited patients at general risk of medication misadventure. Pharmacist interventions usually involved medication review (86.8%), with or without other activities delivered collaboratively with the general practitioner (family physician). Positive effects on primary outcomes related to medication use or clinical outcomes were reported in 19 studies, mixed effects in six studies, and no effect in 13 studies. The results of meta-analyses favored the pharmacist intervention, with significant improvements in blood pressure, glycosylated hemoglobin, cholesterol and Framingham
We list and briefly describe over a hundred pieces of classical and popular music inspired by reasonable astronomical ideas, and we discuss ways that instructors (and those working in informal settings) can use music to enhance an astronomy class or program. Written and Web-based resources for exploring astronomical influences in music are also provided.
This article describes the ways in which practice development can aid Nurse Managers to enhance both efficiency and effectiveness, focussing particularly on the care of older people with delerium and dementia. Practitioners caring for this group of patients in acute general hospitals need specialist skills, particularly skills in working with the unusual ('challenging') behaviours that these patients often exhibit. These skills are rarely present at the point of registration but practice development techniques can facilitate the acquisition of appropriate skills with resultant benefits for both patients and organization. The study contains an outline of the ways in which a practice development approach can be delivered and appraised: the theories are outlined, strategies for delivery of the techniques are described and methods of evaluation are suggested. These theories and techniques are being applied in a project in Portsmouth called 'Rise to the Challenge', which has the specific aim of improving the care of people with delerium and dementia in an acute hospital setting. This project is currently running and will be evaluated in the summer of 2008.

More than 37 million persons or 12.4% of the U.S. population are older than 65 years. These numbers are expected to reach 71.5 million (20% of the population) by 2030. This older population is becoming more racially and ethnically diverse as the overall minority and culturally diverse populations increase. Although the incidence and mortality rates from several major cancers have declined due to advances in cancer care, these advances have lagged among the underserved and more vulnerable racially and culturally diverse populations. Moreover, the disparity between the gender and the racial mix of nurses and the overall population continues to widen. Thus, a growing need for professional nurses and advanced practice nurses with formal educational preparation in all areas of oncology nursing exists. This article (a) highlights significant cancer disparities among diverse populations, (b) describes how cultural belief systems influence cancer care and decision making, and (c) explicates the need to prepare advanced practice nurses for careers that include cancer care of diverse and vulnerable populations through formal oncology educational programs. The "Top 10" reasons for becoming an advanced practice nurse specializing in the oncologic care of patients from diverse and underserved populations are presented. Copyright © 2011 Elsevier Inc.

As the population ages, and individuals desire to remain in their homes as long as possible, the need for in-home care is expected to increase. However, pharmacists have rarely been included in studies of in-home care, and little is known about the prevalence or effectiveness of pharmacists' home-based services in Canada. To identify pharmacy practices in Canada that regularly provide in-home patient care and to identify specific services provided, remuneration obtained, and barriers and facilitators influencing the provision of home-based care. A link to a web-based survey was posted in e-newsletters of provincial, territorial, and national pharmacy associations in Canada. In addition, pharmacists known to the researchers as providing in-home clinical services were contacted directly. The survey was open from October to December 2015. Practices or organizations that performed at least one home visit per week for clinical purposes, with documentation of the services provided, were eligible to participate. One response per practice or organization was allowed. Seventeen practices meeting the inclusion criteria were identified, representing community, hospital, and clinic settings. Home visits were most commonly performed for individuals with complex medication regimens or nonadherence to medication therapy. The most common services were conducting medication reconciliation and reviews and counselling patients about medication adherence. No practices or organizations billed patients for these services, yet lack of remuneration was an important barrier identified by many respondents. Although 12 (71%) of the respondents collected data for evaluative purposes, collection of clinical or health system outcome data was rare. Few Canadian pharmacy practices that provide in-home patient care at least once a week could be identified. Data collection suitable to establish an evidence base for this service was infrequently performed by practices and organizations providing
Engulfing the Observatoire de Paris around 1860, the modernizing city clashed with the increasing precision required by astronomy. Suggestions to transfer the observatory to the suburbs gave rise to intense debates; these provide an enlightening standpoint for studying changes in observation and circulation regimes central to the mutations of both urban cultures and astronomical scientific practices. Moreover, these regime changes took place in a context of constant interaction between the city and the observatory. At practical levels, the changing experience of circulation and observation led to a parceling of the various tasks previously filled by the Paris Observatory and gave rise to an epistemology reminiscent of Latour's network theory.

Theoretical evidence for the existence and behavior of polarization in astronomical spectra is provided. The theory for the study of spectral multiple scattering of arbitrarily polarized light is first developed, and the detailed and integrated spectropolarimetry of a planetary atmosphere is then studied for cases in which the spectra are formed in the presence of either very small nonspherical particles (Rayleigh-Cabannes scattering) or large polydisperse spherical particles (Mie scattering). It is shown in both cases that polarization is indeed present; it increases with the line strength but decreases afterwards as the line becomes very strong and tends to saturation. A polarization reversal is also predicted during latitudinal (pole-to-equator) scan and possibly also during longitudinal (terminator-to-limb) scan of the planet. The reversal happened at all phase angles considered. Our companion article (Forbes and Fymat) will provide observational substantiation to these theoretical predictions.

Full Text Available Several independent astronomical observations in different wavelength bands reveal the existence of much larger quantities of matter than what we would deduce from assuming a solar mass to light ratio. They are very high velocities of individual galaxies within clusters of galaxies, higher than expected rotation rates of stars in the outer regions of galaxies, 21 cm line studies indicative of increasing mass to light ratios with radius in the halos of spiral galaxies, hot gaseous X-ray emitting halos around many elliptical galaxies, and clusters of galaxies requiring a much larger component of unseen mass for the hot gas to be bound. The level of gravitational attraction needed for the spatial distribution of galaxies to evolve from the small perturbations implied by the very slightly anisotropic cosmic microwave background radiation to its current web-like configuration requires much more mass than is observed across the entire electromagnetic spectrum. Distorted shapes of galaxies and other features created by gravitational lensing in the images of many astronomical objects require an amount of dark matter consistent with other estimates. The unambiguous detection of dark matter and more recently evidence for dark energy has positioned astronomy at the frontier of fundamental physics as it was in the 17th century.

Full Text Available INTRODUCTION: Molluscum contagiosum is a common superficial skin infection caused by the poxvirus, Molluscum Contagiosum virus. The study objective is to obtain a better understanding of physician practices and experiences with molluscum contagiosum in order to focus informational and guidance material. METHODS: A cross-sectional survey to assess medical practitioners' knowledge and practices with molluscum contagiosum was conducted using the 2009 DocStyles survey. Questions regarding category and number of molluscum contagiosum patients seen, treatments used and advice given to patients were included in the survey. RESULTS: Dermatologists saw the most cases, with the majority seeing 51-100 molluscum contagiosum cases/year. The most common cases seen were children with multiple lesions and adults with genital lesions. Respondents were most likely to recommend treatment to immunocompromised individuals, HIV patients, adults with genital lesions and children with multiple lesions. Cryotherapy was the top choice for all specialties with the exception of OB/GYNs, whose top choice was curettage. "Avoid intimate contact until lesions resolve", "Avoid touching lesions to reduce further spread", and "Don't be concerned, this will go away" were the top advice choices. DISCUSSION: Most survey respondents have dealt with molluscum contagiosum in their practice during the previous year. Overall, respondents picked appropriate choices for treatment and advice given; however some ineffective or unnecessary treatments were chosen and recommendations to prevent spread were chosen infrequently. Knowledge gaps for appropriate transmission precaution advice might cause unnecessary spread or autoinoculation. This survey has demonstrated that molluscum contagiosum is a common infection seen by many types of practitioners and therefore guidance on treatment considerations and infection control is valuable.

In Libya, cervical cancer is ranked third as the most frequent cancer among women with early diagnosis being shown to reduce morbidity and mortality. Health-care providers can influence women's screening behaviours, and their lack of recommendations for screening can be one of the barriers that affect women's participation in screening programmes. This study aims to assess the health-care provider's perception around cervical cancer screening. In-depth, face-to-face interviews were conducted with 16 health-care providers, from both public and private sectors in Az-Zawiya city, Libya, between February and July of 2014. The interviews were recorded and transcribed, then analysed using thematic analysis. Our findings suggest that health-care providers did not provide sufficient information regarding cervical cancer screening for women who attend health-care facilities. The results highlight the role played by health-care professionals in motivating women to attend cervical cancer screening programs, and the need for health education of health-care providers to offer a precious advice regarding the screening. On the other hand, health-care providers highlighted that implementation of reminding system of cervical cancer screening will support them to improve screening attendance. In addition, health-care providers stressed the necessity for educational and awareness campaigns of cervical cancer screening among Libyan women. © 2016 John Wiley & Sons Ltd.

Healthcare organisations have a responsibility for ensuring that the governance of workplace settings creates a culture that supports good professional practice. Encouraging such a culture needs to start from an understanding of the factors that make it difficult for health professionals to raise issues of concern in relation to patient safety. The focus of this study is to determine whether a customised education intervention, developed as part of the study, with interns and senior house officers (SHOs) can imbue a culture of medical professionalism in relation to patient safety and support junior doctors to raise issues of concern, while shaping a culture of responsiveness and learning.

Romanian astronomy has a more than 2000-year old tradition, which is, however, little known abroad. The first known archive of astronomical information is the Dacian sanctuary at Sarmizegetusa Regia, erected in the first century AD, having similarities with that of Stonehenge. After a gap of more than 1000 years, more sources of astronomical information become available, mainly records of astronomical events. Monasteries were the safest storage places of these genuine archives. We present a classification of the ways of storing astronomical information, along with characteristic examples.
membership of CERN and the European Space Agency. Both of which provide UK scientists with access to world-class facilities that, on a national basis alone, we could not begin to consider. Joining ESO consolidates this strategy for UK astronomers and redresses the balance of UK ground based facilities compared to other European countries, Japan and the US." The ESO Director General, Dr. Catherine Cesarsky , is "delighted that the UK has joined our organisation. When ESO was created nearly 40 years ago, the UK was planning for its own facilities and decided not to join. However, the impressive scientific and technological advances since then, coupled with ESO's emergence as a prime player on the European research scene have convinced our UK colleagues of the great advantages of presenting a united European face in astronomy through ESO." Ian Halliday added,"Membership of ESO will ensure that UK astronomy remains at the cutting edge of scientific research and discovery, whilst playing an integral role in developing the next generation of ground based facilities. This strategy also endorses the recommendations of the 'International Perceptions of UK Research in Physics and Astronomy', an independent review which recommended joining ESO".

With some justification, many amateur astronomers believe astrophysics is a very difficult subject, requiring at least degree-level mathematics to understand it properly. This isn’t necessarily the case. Mike Inglis' quantitative approach to the subject explains all aspects of astrophysics in simple terms and cuts through the incomprehensible mathematics with which this fascinating subject is all too often associated. Astrophysics is Easy! begins by looking at the H-R diagram and other basic tools of astrophysics, then ranges across the universe, from a first look at the interstellar medium and nebulae, through the birth, evolution and death of stars, to the physics of galaxies and clusters of galaxies. A unique feature of this book is the way that Dr. Inglis lists example objects for practical observation at every stage, so that practical astronomers can go and look at the object or objects under discussion – using only easily-available commercial amateur equipment.

The US Virtual Astronomical Observatory was a software infrastructure and development project designed both to begin the establishment of an operational Virtual Observatory (VO) and to provide the US coordination with the international VO effort. The concept of the VO is to provide the means by which an astronomer is able to discover, access, and process data seamlessly, regardless of its physical location. This paper describes the origins of the VAO, including the predecessor efforts within the US National Virtual Observatory, and summarizes its main accomplishments. These accomplishments include the development of both scripting toolkits that allow scientists to incorporate VO data directly into their reduction and analysis environments and high-level science applications for data discovery, integration, analysis, and catalog cross-comparison. Working with the international community, and based on the experience from the software development, the VAO was a major contributor to international standards within the International Virtual Observatory Alliance. The VAO also demonstrated how an operational virtual observatory could be deployed, providing a robust operational environment in which VO services worldwide were routinely checked for aliveness and compliance with international standards. Finally, the VAO engaged in community outreach, developing a comprehensive web site with on-line tutorials, announcements, links to both US and internationally developed tools and services, and exhibits and hands-on training at annual meetings of the American Astronomical Society and through summer schools and community days. All digital products of the VAO Project, including software, documentation, and tutorials, are stored in a repository for community access. The enduring legacy of the VAO is an increasing expectation that new telescopes and facilities incorporate VO capabilities during the design of their data management systems.

During the last year the US SIMBAD Gateway Project continued to provide services like user registration to the US users of the SIMBAD database in France. Currently there are over 4500 US users registered. We also provided user support by answering questions from users and handling requests for lost passwords when still necessary. Even though almost all users now access SIMBAD without a password, based on hostnames/IP addresses, there are still some users that need individual passwords. We continued to maintain the mirror copy of the SIMBAD database on a server at SAO. This allows much faster access for the US users. During the past year we again moved this mirror to a faster server to improve access for the US users. We again supported a demonstration of the SIMBAD database at the meeting of the American Astronomical Society in January. We provided support for the demonstration activities at the SIMBAD booth. We paid part of the fee for the SIMBAD demonstration. We continued to improve the cross-linking between the SIMBAD project and the Astrophysics Data System. This cross-linking between these systems is very much appreciated by the users of both the SIMBAD database and the ADS Abstract Service. The mirror of the SIMBAD database at SA0 makes this connection faster for the US astronomers. We exchange information between the ADS and SIMBAD on a daily basis. During the last year we also installed a mirror copy of the Vizier system from the CDS, in addition to the SIMBAD mirror.

To compare the clinical consultations provided by American and Kenyan pharmacy students in an acute care setting in a developing country. The documented pharmacy consultation recommendations made by American and Kenyan pharmacy students during patient care rounds on an advanced pharmacy practice experience at a referral hospital in Kenya were reviewed and classified according to type of intervention and therapeutic area. The Kenyan students documented more interventions than American students (16.7 vs. 12.0 interventions/day) and provided significantly more consultations regarding human immunodeficiency virus (HIV) and antibiotics. The top area of consultations provided by American students was cardiovascular diseases. American and Kenyan pharmacy students successfully providing clinical pharmacy consultations in a resource-constrained, acute-care practice setting suggests an important role for pharmacy students in the reconciliation of prescriber orders with medication administration records and in providing drug information.
Full Text Available Abstract Background Fluid resuscitation during cardiac surgery is common with significant variability in clinical practice. Our goal was to investigate current practice patterns of fluid volume expansion in patients undergoing cardiac surgeries in the USA. Methods We conducted a cross-sectional online survey of 124 cardiothoracic surgeons, cardiovascular anesthesiologists, and perfusionists. Survey questions were designed to assess clinical decision-making patterns of intravenous (IV fluid utilization in cardiovascular surgery for five types of patients who need volume expansion: (1 patients undergoing cardiopulmonary bypass (CPB without bleeding, (2 patients undergoing CPB with bleeding, (3 patients undergoing acute normovolemic hemodilution (ANH, (4 patients requiring extracorporeal membrane oxygenation (ECMO or use of a ventricular assist device (VAD, and (5 patients undergoing either off-pump coronary artery bypass graft (OPCABG surgery or transcatheter aortic valve replacement (TAVR. First-choice fluid used in fluid boluses for these five patient types was requested. Descriptive statistics were performed using Kruskal-Wallis test and follow-up tests, including t tests, to evaluate differences among respondent groups. Results The most commonly preferred indicators of volume status were blood pressure, urine output, cardiac output, central venous pressure, and heart rate. The first choice of fluid for patients needing volume expansion during CPB without bleeding was crystalloids, whereas 5% albumin was the most preferred first choice of fluid for bleeding patients. For volume expansion during ECMO or VAD, the respondents were equally likely to prefer 5% albumin or crystalloids as a first choice of IV fluid, with 5% albumin being the most frequently used adjunct fluid to crystalloids. Surgeons, as a group, more often chose starches as an adjunct fluid to crystalloids for patients needing volume expansion during CPB without bleeding. Surgeons

Treatment protocols for childhood nephrotic syndrome are highly variable between providers and care centres. We conducted a qualitative study to understand the complex multilevel processes that lead to practice variation and influence provider management of nephrotic syndrome. Focus groups with multidisciplinary pediatric nephrology care providers (n = 67) from 10 Canadian pediatric nephrology centres that had more than 1 pediatric nephrologist were conducted between September 2013 and April 2015. Focus group discussions were guided by the Ottawa Model for Research Use. We used a semistructured interview guide to elicit participants' perspectives regarding 1) the work setting and context of the clinical environment, 2) reasons for variation at the provider level and 3) clinical practice guidelines for nephrotic syndrome. Focus group discussions were transcribed and analyzed concurrently with the use of qualitative content analysis. Emerging themes were grouped into 2 categories: centre-level factors and provider-level factors. At the centre level, the type of care model used, clinic structures and resources, and lack of communication and collaboration within and between Canadian centres influenced care variation. At the provider level, use of experiential knowledge versus empirical knowledge and interpretation of patient characteristics influenced provider management of nephrotic syndrome. Centre- and provider-level factors play an important role in shaping practice differences in the management of childhood nephrotic syndrome. Further research is needed to determine whether variation in care is associated with disparities in outcomes. Copyright 2017, Joule Inc. or its licensors.

The implementation of a new birthing facility in a country such as Brazil requires an extensive in-depth analysis of the challenges faced. The aim of this study was to explore beliefs, values, experiences, and practices related to the provision of birthing and neonatal care with the implementation of a new birth care facility structure called alongside midwifery units in Brazil. The study utilizes an ethnographic method to evaluate members of a Brazilian public hospital's midwifery unit. The ethnographic study focuses on the cultural theme of "between the proposed and the possible": the following birthing care guidelines require overcoming numerous obstacles, and four other cultural subthemes toward revealing the analyzed birth care team's perspectives. The study found that prior training and preparation of all members of the care team, as well as the provision of adequate institutional infrastructure are essential for the implementation of a new and innovative birthing care center.

Social media is a relatively new form of media that includes social networks for communication dissemination and interaction. Patients, physicians, and other users are active on social media including the microblogging platform Twitter. Many online resources are available to facilitate joining and adding to online conversations. Social media can be used for professional uses, therefore, we include anecdotes of physicians starting on and implementing social media successfully despite the limits of time in busy practices. Various applications demonstrating the utility of social media are explored. These include case discussions, patient groups, research collaborations, medical education, and crowdsourcing/crowdfunding. Social media is integrating into the professional workflow for some individuals and hematology/oncology societies. The potential for improving hematology care and research is just starting to be explored.

Entrepreneurs are known for opportunity recognition--that is, "How can I start a business to make money from this opportunity?" However, once a commercial entity is formed to take advantage of an opportunity, the leadership priority shifts from entrepreneurial to strategic. A strategic perspective leverages limited resources to position a business for future success relative to rivals in a competitive environment. Often, the talents needed for one priority are not the same as those needed for the other. This article, the first part of a two-part article, intends to simplify the transition from an entrepreneurial to a strategic focus. It walks an entrepreneur through the strategic management planning process using a fictional business. The various tasks in the process (i.e., mission, vision, internal analysis, external analysis) are illustrated with examples from a typical primary physician's private practice. The examples show how the strategic management tasks are interrelated and ultimately lead to a philosophical approach to managing a business.

The latest cholesterol guidelines have shifted focus from achieving low-density lipoprotein cholesterol (LDL-C) targets toward statin use and intensity guided by atherosclerotic cardiovascular disease (ASCVD) risk. Statin use and intensity were evaluated in 5,905 statin-eligible primary or secondary prevention patients from 138 PALM Registry practices. Overall, 74.7% of eligible adults were on statins; only 42.4% were on guideline-recommended intensity. Relative to primary prevention patients, ASCVD patients were more likely to be on a statin (83.6% vs 63.4%, Pobesity, hypertension, and lower 10-year ASCVD risk were associated with increased odds of receiving recommended intensity. Among ASCVD patients, those with coronary artery disease were more likely to be on recommended intensity than cerebrovascular or peripheral vascular disease patients (OR 1.71, 95% CI 1.41-2.09), as were those seen by cardiologists (OR 1.43, 95% CI 1.12-1.83). Median LDL-C levels were highest among patients not on statins (124.0 mg/dL) and slightly higher among those on lower-than-recommended intensity compared with recommended-therapy recipients (88.0 and 84.0 mg/dL, respectively; P≤.0001). In routine contemporary practice, 1 in 4 guideline-eligible patients was not on a statin; less than half were on the recommended statin intensity. Untreated and undertreated patients had significantly higher LDL-C levels than those receiving guideline-directed statin treatment. Copyright © 2017 Elsevier Inc. All rights reserved.
This paper depicts some aspects of the formative process of the Japanese optical and infrared astronomical community in the post-war period, featuring the transition of the National Astronomical Observatory of Japan(NAOJ). We take up three cases of telescope construction, examining their background and their contribution to the Japanese astronomical community. Through these cases, the characteristics of traditions and cultures of optical and infrared astronomy in Japan are considered. Although the Tokyo Astronomical Observatory (TAO) of the University of Tokyo, the predecessor of NAOJ, was originally founded as an agency for practical astronomical observation such as time and almanac service, it has become an international centre for all types of astrophysical research. Research and development of telescopes and observational instruments have become an important part of the astronomers' practice. Now, however, a number of Japanese universities are planning to have their own large to middle-sized telescopes, and a new style of astronomical research is emerging involving astrophysical studies utilising data acquired from the Virtual Observatory, so there is a distinct possibility that the status of the NAOJ will change even further in the future.

Imaging services constitute a huge portion of the of the total dollar investment within the health care enterprise. Accordingly, this generates competition among medical specialties organized along service lines for their pieces of the pie and increased scrutiny from third-party payers and government regulators. These market and political forces create challenge and opportunity for a hospital-based radiology practice. Clearly, change that creates or builds greater value for patients also creates sustainable competitive advantage for a radiology practice. The somewhat amorphous concept of quality constitutes a significant value driver for innovation in this scenario. Quality initiatives and programs seek to define and manage this amorphous concept and provide tools for a radiology practice to create or build more value. Leadership and the early adoption of these inevitable programs by a radiology practice strengthens relationships with hospital partners and slows the attrition of imaging service lines to competitors.

Antibiotic stewardship education for health care providers provides a foundation of knowledge and an environment that facilitates and supports optimal antibiotic prescribing. There is a need to extend this education to medical students and health care trainees. Education using passive techniques is modestly effective for increasing prescriber knowledge, whereas education using active techniques is more effective for changing prescribing behavior. Such education has been shown to enhance other antibiotic stewardship interventions. In this review, the need and suggested audience for antibiotic stewardship education are highlighted, and effective education techniques are recommended for increasing knowledge of antibiotics and improving their use.

This carefully researched monograph is a historical investigation of the illustrated Aratea astronomical manuscript and its many interpretations over the centuries. Aratus' 270 B.C.E. Greek poem describing the constellations and astrological phenomena was translated and copied over 800 years into illuminated manuscripts that preserved and illustrated these ancient stories about the constellations. The Aratea survives in its entirety due to multiple translations from Greek to Latin and even to Arabic, with many illuminated versions being commissioned over the ages. The survey encompasses four interrelated disciplines: history of literature, history of myth, history of science, and history of art. Aratea manuscripts by their nature are a meeting place of these distinct branches, and the culling of information from historical literature and from the manuscripts themselves focuses on a wider, holistic view; a narrow approach could not provide a proper prospective. What is most essential to know about this work is...

The Star Formation/ISM Astronomical Database (hereafter SFD) will be a set of on-line services adding value to existing data archives and published journals, along the lines of the very successful NASA/IPAC Extragalactic Database (NED) and SIMBAD projects but with a focus on star formation an the interstellar medium (ISM) within the Milky Way. Unlike NED and SIMBAD, however, the SFD must deal with multi-wavelength measurements of extended regions and cross-correlative relationships between disparate measurements. The SFD will rely heavily on existing databases, primarily adding data content and connectivity between datasets around the world, and custom tailoring of existing tools to provide interfaces (programming API, Web, and JAVA GUI) specific to this application. We consider the SFD as a valuable component in the broader context of a future Virtual Observatory.

The Jesuit scientist Christopher Clavius (1538-1612) has been the most influential teacher of the renaissance. His contributions to algebra, geometry, astronomy and cartography are enormous. He paved the way, with his texts and his teaching for 40 years in the the Collegio Romano, to the development of these sciences and their fruitful spread all around the World, along the commercial paths of Portugal, which become also the missionary paths for the Jesuits. The books of Clavius were translated into Chinese, by one of his students Matteo Ricci "Li Madou" (1562-1610), and his influence for the development of science in China was crucial. The Jesuits become skilled astronomers, cartographers and mathematicians thanks to the example and the impulse given by Clavius. This success was possible also thanks to the contribution of Clavius in the definition of the Ratio Studiorum, the program of studies, in the Jesuit colleges, so influential for the whole history of modern Europe and all western World.

In this work, four ancient monuments of astronomical significance found in Athens and still kept in the same city in good condition are presented. The first one is the conical sundial on the southern slope of the Acropolis. The second one is the Tower of the Winds and its vertical sundials in the Roman Forum of Athens, a small octagonal marble tower with sundials on all 8 of its sides, plus a water-clock inside the tower. The third monument-instrument is the ancient clepsydra of Athens, one of the findings from the Ancient Agora of Athens, a unique water-clock dated from 400 B.C. Finally, the fourth one is the carved ancient Athenian calendar over the main entrance of the small Byzantine temple of the 8th Century, St. Eleftherios, located to the south of the temple of the Annunciation of Virgin Mary, the modern Cathedral of the city of Athens.

Accessing scientific data through an online portal can be a frustrating task. The concept of making web interfaces easy to use known as "usability" has been thoroughly researched in the field of e-commerce but has not been explicitly addressed in the atmospheric sciences. As more observation stations are installed, satellite missions flown, models run, and field campaigns performed, large amounts of data are produced. Portals on the Internet have become the favored mechanisms to share this information and are ever increasing in number. Portals are often created without being tested for usability with the target audience though the expenses of testing are low and the returns high. To remain competitive and relevant in the provision of atmospheric data, it is imperative that developers understand design elements of a successful portal to make their product stand out among others. This presentation informs the audience of the benefits and basic principles of usability for web pages presenting atmospheric data. We will also share some of the best practices and recommendations we have formulated from the results of usability testing performed on two data provision web sites hosted by the Western Regional Climate Center.

Provision of dietary counseling in the office setting is enhanced by using team-based care and electronic tools. Effective provider-patient communication is essential for fostering behavior change: the key component of lifestyle medicine. The principles of communication and behavior change are skill-based and grounded in scientific theories and models. Motivational interviewing and shared decision making, a collaboration process between patients and their providers to reach agreement about a health decision, is an important process in counseling. The stages of change, self-determination, health belief model, social cognitive model, theory of planned behavior, and cognitive behavioral therapy are used in the counseling process.

Providing equal access to health care is an important objective in most health care systems. It is especially pertinent in systems like the Swedish primary care market, where providers are free to establish themselves in any part of the country. To improve equity in access to care, 15 out 21 county...... capitation on the supply of private primary care centers. We use a dataset that combines information on all primary care centers in Sweden during 2005-2013, the payment system and other conditions for establishing new primary care centers used in the county councils, and demographic, geographic......-adjusted capitation significantly increase the number of private primary care centers in areas with relatively high Care Need Index values. The adjustment results in a changed distribution of private centers within county councils; the total number of private centers does not increase in county councils using care...

Basal insulin remains the mainstay of treatment of type 2 diabetes when diet changes and exercise in combination with oral drugs and other injectable agents are not sufficient to control hyperglycemia. Insulin therapy should be individualized, and several factors influence the choice of basal insulin; these include pharmacological properties, patient preferences, and lifestyle, as well as health insurance plan formularies. The recent availability of basal insulin formulations with longer durations of action has provided further dosing flexibility; however, patients may need to switch agents throughout therapy for a variety of personal, clinical, or economic reasons. Although a unit-to-unit switching approach is usually recommended, this conversion strategy may not be appropriate for all patients and types of insulin. Glycemic control and risk of hypoglycemia must be closely monitored by health care providers during the switching process. In addition, individual changes in care and formulary coverage need to be adequately addressed in order to enable a smooth transition with optimal outcomes.

The social and institutional environments in which informal healthcare providers operate shape their health and business practices, particularly in contexts where regulatory enforcement is weak. In this study, we adopt a social capital perspective to understanding the social networks on which proprietary and patent medicine vendors (PPMVs) in Nigeria rely for support in the operation of their shops. Data are drawn from 70 in-depth interviews with PPMVs in three states, including interviews with local leaders of the PPMV professional association. We find that PPMVs primarily relied on more senior colleagues and formal healthcare professionals for informational support, including information about new medicines and advice on how to treat specific cases of illness. For instrumental support, including finance, start-up assistance, and intervention with regulatory agencies, PPMVs relied on extended family, the PPMVs with whom they apprenticed, and the leaders of their professional association. PPMVs' networks also provided continual reinforcement of what constitutes good PPMV practice through admonishments to follow scope of practice limitations. These informal reminders, as well as monitoring activities conducted by the professional association, served to reinforce PPMVs' concern with avoiding negative customer health outcomes, which were perceived to be detrimental to their business reputations. That PPMVs' networks both encouraged practices to reduce the likelihood of poor health outcomes, and provided advice regarding customers' health conditions, highlights the potential impact of informal providers' access to different forms of social capital on their delivery of health services, as well as their success as microenterprises.

Patients respond very positively with nurses when they talk to them about their health related problems. This cross sectional study was carried out among nurses working in Gulf Medical College hospital and Research centre, Ajman, UAE to assess the their attitude in providing tobacco cessation counselling or advise to their patients and potential barriers they face in providing tobacco cessation care. 108 nurses participated in the study. Among the nurses 87% were females, the majority were aged between 25 and 34 years, and 46.3% had a work experience of less than 5 years. Among the nurses who participated in the survey, 99.1% felt that the hospital stay was a suitable time for nurses to create awareness on tobacco and health to the patients and had a positive attitude towards creating awareness on tobacco and health to the patients. Only 0.9% had a negative attitude towards creating awareness on tobacco and health and they felt that patients might not listen to them. All nurses, irrespective of their socio-demographic characteristics had a positive attitude to motivating patients to quit tobacco use. Currently, 70.4% regularly advise their patients to avoid tobacco products. Potential barriers pointed out by nurses were: lack of time (6.3%) patients may not appreciate it (90.6%) and not part of their job (3.1%). The study concludes that nurses have a positive attitude in providing tobacco cessation care to their patients and they can utilize their unique knowledge and know-how to promote tobacco cessation and prevent the spread of this public health crisis. Providing advice and support for tobacco cessation by nurses would increase the chance of patients stopping tobacco use. This will create an enabling environment and greater potential for public health persons to fight the epidemic with greater vigour

R&E Networks have been in the business of serving the needs of research and education for decades. A recent development is that more and more R&E Networks are required to support the overall business of research and education for their customers. As R&E institutes have felt the pressure from governments to become more efficient and cost-effective, their interest has turned to cloud solutions for scientific applications as well as back-end office systems. The use of clouds, both commercial and private, is increasing rapidly. Large scale connectivity with cloud providers is a rather new but important area, in which R&E Networks are trying to find their way to add value. Connectivity with commercial cloud providers nowadays is an important topic, and it is becoming crucial that advice to policy makers, decision makers and procurers is given so that over time it will lead to a coherent, scalable and increasingly cost-effective solution for connecting to cloud service providers.

To compare the obesity related training, practices, and perceptions of home child care providers and center care providers. A self-administered survey was collected from child care providers who attended local child care training workshops in east central Illinois from March 2009 to August 2010. Study results were based on responses from 88 home care providers and 94 center providers. The survey questions addressed child care providers' training in the prior year, their obesity prevention practices including written policies, their perceptions of influences on children's health, and factors determining food menu selection. Paired t tests and Chi-square tests were used to compare the difference by child care type. 81.9% of home care providers and 58.6% of center care providers received nutrition training, while 66.7 and 43.0% of these providers received physical activity training, respectively. Nutrition content, guidelines or state regulations, and food availability were the most important factors that influenced both types of care providers' food service menus. Both care provider types perceived they have less influence on children's food preferences, eating habits, and weight status compared to the home environment. However, home care providers perceived a smaller discrepancy between the influences of child care and home environments compared to center care providers. Compared to center providers, home care providers were more likely to have had training, be involved with health promotion activities, and rate their influence higher on children's health behaviors. Findings underscore the need for obesity prevention efforts in both types of child care settings.

Substance abuse agencies have been slow to adopt and implement evidence-based practices (EBPs), due in part to poor provider morale and organizational climates that are not conducive to successful learning and integration of these practices. Person-organization fit theory suggests that alignment, or fit, between provider- and agency-level characteristics regarding the implementation of EBPs may influence provider morale and organizational learning climate and, thus, implementation success. The current study hypothesized that discrepancies, or lack of fit, between provider- and agency-level contextual factors would negatively predict provider morale and organizational learning climate, outcomes shown to be associated with successful EBP implementation. Direct service providers (n = 120) from four substance abuse treatment agencies responded to a survey involving provider morale, organizational learning climate, agency expectations for EBP use, agency resources for EBP use, and provider attitudes towards EBP use. Difference scores between combinations of provider- and agency-level factors were computed to model provider-agency fit. Quadratic regression analyses were conducted to more adequately and comprehensively model the level of the dependent variables across the entire "fit continuum". Discrepancies, or misfit, between agency expectations and provider attitudes and between agency resources and provider attitudes were associated with poorer provider morale and weaker organizational learning climate. For all hypotheses, the curvilinear model of provider-agency discrepancies significantly predicted provider morale and organizational learning climate, indicating that both directions of misfit (provider factors more favorable than agency factors, and vice-versa) were detrimental to morale and climate. However, outcomes were most negative when providers viewed EBPs favorably, but perceived that agency expectations and resources were less supportive of EBP use. The
Full Text Available Abstract Background The emergence of influenza strains that are resistant to commonly used antivirals has highlighted the need to develop new compounds that target viral gene products or host mechanisms that are essential for effective virus replication. Existing assays to identify potential antiviral compounds often use high throughput screening assays that target specific viral replication steps. To broaden the search for antivirals, cell-based replication assays can be performed, but these are often labor intensive and have limited throughput. Results We have adapted a traditional virus neutralization assay to develop a practical, cell-based, high throughput screening assay. This assay uses viral neuraminidase (NA as a read-out to quantify influenza replication, thereby offering an assay that is both rapid and sensitive. In addition to identification of inhibitors that target either viral or host factors, the assay allows simultaneous evaluation of drug toxicity. Antiviral activity was demonstrated for a number of known influenza inhibitors including amantadine that targets the M2 ion channel, zanamivir that targets NA, ribavirin that targets IMP dehydrogenase, and bis-indolyl maleimide that targets protein kinase A/C. Amantadine-resistant strains were identified by comparing IC50 with that of the wild-type virus. Conclusion Antivirals with specificity for a broad range of targets are easily identified in an accelerated viral inhibition assay that uses NA as a read-out of replication. This assay is suitable for high throughput screening to identify potential antivirals or can be used to identify drug-resistant influenza strains.

Background Attitudes and views are critical to the adoption of innovation. While there have been broadening calls for a standardized dental diagnostic terminology, little is known about the views of private practice dental team members towards the adoption of such a terminology. Methods A survey was developed using validated questions identified through literature review. Domain experts’ input allowed for further modifications. The final survey was administered electronically to 814 team members at a multi-office practice based in the Pacific Northwest. Results Response proportion was 92%. The survey had excellent reliability (Cronbach alpha coefficient = 0.87). Results suggested that participants showed, in general, positive attitudes and beliefs towards using a standardized diagnostic terminology in their practices. Additional written comments by participants highlighted the potential for improved communication with use of the terminology. Conclusions Dental providers and staff in one multi-office practice showed positive attitudes towards the use of a diagnostic terminology, specifically they believed it would improve communication between the dentist and patient as well as among providers, while expressing some concerns if using standardized dental diagnostic terms helps clinicians to deliver better dental care. Practical Implications As the dental profession is advancing towards the use of standardized diagnostic terminologies, successful implementation will require that dental team leaders prepare their dental teams by gauging their attitude toward the use of such a terminology.

Teen dating violence (TDV) is a serious and potentially lethal form of relationship violence in adolescence. TDV is highly correlated with several outcomes related to poor physical and mental health. Although incidence and prevalence data indicate high rates of exposure to TDV among adolescents throughout the United States, significant confusion remains in healthcare communities concerning the definition and implications of TDV. Additionally, healthcare providers are uncertain about effective screening and intervention methods. The article will review the definition and epidemiology of TDV and discuss possible screening and intervention strategies. TDV research is a relatively new addition to the field of relationship violence. Although some confusion remains, the definition and epidemiology of TDV are better understood, which has greatly led to effective ways in which to screen and intervene when such violence is detected. Universal screening with a focus on high-risk subgroups combined with referrals to local and national support services are key steps in reducing both primary and secondary exposure. TDV is a widespread public health crisis with serious short-term and long-term implications. It is necessary for pediatric and adolescent healthcare providers to be aware of TDV and its potential repercussions, as well as possible methods for screening and intervention. More research is needed to better understand TDV as well as to further define effective screening and intervention protocol for the clinical environment.

Like other sub-Saharan Africa, in Ethiopia there is a shortage of adequate and safe blood supplies. Health care providers are potential resource and promoter of voluntary blood donation. This study was conducted to determine the knowledge, attitude and practice towards blood donation among health care providers in Bahir Dar City, Ethiopia. Paper based questionnaire was distributed to 276 health care providers from May 01 to June 30, 2016. Overall, 42.8% had donated blood at least once. Of these, males accounted for 60%. The median age of blood donors was 26 years. Voluntary-unpaid donation was 21.2%. Overall, 75.5% health care providers were knowledgeable. The levels of knowledge were significantly different among different disciplines (One-way ANOVA; F=69.7; P=0.004). Males were more knowledgeable than females (Pattitude was 78.6%. Previous practice of blood donation determined the odds of favorable attitude to be a future regular voluntary-unpaid blood donor (OR: 5.7, 95% CI: 3.2-10.4). Majority of health care providers had adequate knowledge and favorable attitude. However, voluntary-unpaid donation practice (21.1%) was lower compared to 100% target of voluntary-unpaid donation. There should be motivation packages to enhance voluntary-unpaid blood donation among health care professionals. Copyright © 2017 Elsevier Ltd. All rights reserved.

This survey intended to determine how the implementation of office-based IV deep sedation by a third party provider (OIVSED) impacted the traditional sedation practices employed in pediatric dentistry private practice settings. A digital survey was e-mailed to 924 members of the American Academy of Pediatric Dentistry practicing in California, Florida, and New York, chosen because these states had large samples of practicing pediatric dentists in geographically disparate locations. 151 pediatric dentists using OIVSED responded to the survey. Improved efficiency, safety and quality of care provided, and increased parental acceptance were reported advantages of this service. Although less costly than hospital-based general anesthesia, the average fee for this service was a deterrent to some parents considering this option. Sixty-four percent of respondents continued to provide traditional sedation modalities, mostly oral sedation, in their offices, as parenteral routes taught in their training programs were less often selected. OIVSED users reported both a reduction in the use of traditional sedation modalities in their offices and use of hospital-based GA services in exchange for perceived improvements in efficiency, safety and quality of care delivered. Patient costs, in the absence of available health insurance coverage, inhibited accessing this service by some parents.

Despite growing social acceptance, the LGBTQ population continues to face barriers to healthcare including fear of stigmatization by healthcare providers, and providers' lack of knowledge about LGBTQ-specific health issues. This analysis focuses on the assessment of quantitative and qualitative responses from a subset of providers who identified as specialists that treat one or more of the seven cancers that may be disproportionate in LGBTQ patients. A 32-item web-based survey was emailed to 388 oncology providers at a single institution. The survey assessed: demographics, knowledge, attitudes, and practice behaviors. Oncology providers specializing in seven cancer types had poor knowledge of LGBTQ-specific health needs, with fewer than half of the surveyed providers (49.5%) correctly answering knowledge questions. Most providers had overall positive attitudes toward LGBTQ patients, with 91.7% agreeing they would be comfortable treating this population, and would support education and/or training on LGBTQ-related cancer health issues. Results suggest that despite generally positive attitudes toward the LGBTQ population, oncology providers who treat cancer types most prevalent among the population, lack knowledge of their unique health issues. Knowledge and practice behaviors may improve with enhanced education and training on this population's specific needs.

The geographic information is of great importance for the site survey of ground-based telescopes. Especially, an effective utilization of the geographic information system (GIS) has been one of the most significant methods for the remote analysis of modern site survey. The astronomical site survey should give consideration to the following geographical conditions: a large relative fall, convenient traffic conditions, and far away from populated areas. Taking into account of the convenience of construction and maintenance of the observatories as well as the living conditions of the scientists-in-residence, the optimum candidate locations may meet the conditions to be at a altitude between 3000 m and 5000 m and within one-hour drive from villages/towns. In this paper, as an example, we take the regions of the Great Baicao mountain ridge at Dayao county in Yunnan province to research the role of the GIS for site survey task. The results indicate that the GIS can provide accurate and intuitive data for us to understand the three dimensional landforms, rivers, roads, villages, and the distributions of the electric power as well as to forecast the tendency of the population and city development around. According to the analysis based on the GIS, we find that the top of the Great Baicao mountain ridge is flat and droughty. There are few inhabitants to distribute around the place while the traffic conditions are convenient. Moreover, it is a natural conservation area protected by the local government, and no industry with pollution sources exists in this region. Its top is 1500 m higher than the nearby village 10 km away, and 1800 m higher than the town center 50 km away. The Great Baicao mountain ridge is definitely an isolated peak in the area of the Yi nationality of Yunnan. Therefore, the GIS data analysis is a very useful for the remote investigation stage for site survey, and the GIS is the indispensable source for modern astronomical site survey.
Engaging students in the analysis of authentic scientific data is an effective way to teach them about the scientific process and to develop their problem solving, teamwork and communication skills. In astronomy several image processing and analysis software tools have been developed for use in school environments. However, the practical implementation in the classroom is often difficult because the teachers may not have the comfort level with computers necessary to install and use these tools, they may not have adequate computer privileges and/or support, and they may not have the time to learn how to use specialized astronomy software. To address this problem, we have developed a set of activities in which students analyze astronomical images using basic tools provided in PowerPoint. These include measuring sizes, distances, and angles, and blinking images. In contrast to specialized software, PowerPoint is broadly available on school computers. Many teachers are already familiar with PowerPoint, and the skills developed while learning how to analyze astronomical images are highly transferable. We will discuss several practical examples of measurements, including the following: -Variations in the distances to the sun and moon from their angular sizes -Magnetic declination from images of shadows -Diameter of the moon from lunar eclipse images -Sizes of lunar craters -Orbital radii of the Jovian moons and mass of Jupiter -Supernova and comet searches -Expansion rate of the universe from images of distant galaxies

La Caille was one of the observational astronomers and geodesists who followed Newton in developing ideas about celestial mechanics and the shape of the earth. He provided data to the great 18th-century mathematicians involved in understanding the complex gravitational effects that the heavenly bodies have on one another. Observing from the Cape of Good Hope, he made the first ever telescopic sky survey and gave many of the southern constellations their present-day names. He measured the paths of the planets and determined their distances by trigonometry. In addition, he made a controversial measurement of the radius of the earth that seemed to prove it was pear-shaped. On a practical level, La Caille developed the method of `Lunars' for determining longitudes at sea. He mapped the Cape. As an influential teacher he propagated Newton's theory of universal gravitation at a time when it was only beginning to be accepted on the European continent. This book gives the most comprehensive overview so far avail...

Amateur astronomers who have been disappointed by the results of an observing session can still gain useful experience in a seemingly “failed” night at the telescope. In a world with imperfect seeing conditions, incredible observing sessions are often mixed with less inspiring ones, discouraging the amateur observer. This book is designed to help novice observers take something worthwhile away each and every time they go out under the night sky, regardless of what was originally planned. Almost every observer remembers his first sight of Ringed Saturn, hanging majestically in the blackness of space. Practitioners agree that visual observing is special. Real-time observations at the eyepiece can provide fleeting yet intense feelings that connect us with the universe. But when expectations aren’t met at the eyepiece, there are other ways to profit from the practice of astronomy. These rewards, though less showy, are well worth cultivating. This book will help you see what constitutes a “successful” vi...
Full Text Available BACKGROUND: WHO recommends prompt diagnosis and quinine plus clindamycin for treatment of uncomplicated malaria in the first trimester and artemisinin-based combination therapies in subsequent trimesters. We undertook a systematic review of women's access to and healthcare provider adherence to WHO case management policy for malaria in pregnant women. METHODS AND FINDINGS: We searched the Malaria in Pregnancy Library, the Global Health Database, and the International Network for the Rational Use of Drugs Bibliography from 1 January 2006 to 3 April 2014, without language restriction. Data were appraised for quality and content. Frequencies of women's and healthcare providers' practices were explored using narrative synthesis and random effect meta-analysis. Barriers to women's access and providers' adherence to policy were explored by content analysis using NVivo. Determinants of women's access and providers' case management practices were extracted and compared across studies. We did not perform a meta-ethnography. Thirty-seven studies were included, conducted in Africa (30, Asia (4, Yemen (1, and Brazil (2. One- to three-quarters of women reported malaria episodes during pregnancy, of whom treatment was sought by >85%. Barriers to access among women included poor knowledge of drug safety, prohibitive costs, and self-treatment practices, used by 5%-40% of women. Determinants of women's treatment-seeking behaviour were education and previous experience of miscarriage and antenatal care. Healthcare provider reliance on clinical diagnosis and poor adherence to treatment policy, especially in first versus other trimesters (28%, 95% CI 14%-47%, versus 72%, 95% CI 39%-91%, p = 0.02, was consistently reported. Prescribing practices were driven by concerns over side effects and drug safety, patient preference, drug availability, and cost. Determinants of provider practices were access to training and facility type (public versus private. Findings were

Full Text Available Abstract Background The goal of this study is to extend research on evidence-based practice (EBP implementation by examining the impact of organizational type (public versus private and organizational support for EBP on provider attitudes toward EBP and EBP use. Both organization theory and theory of innovation uptake and individual adoption of EBP guide the approach and analyses in this study. We anticipated that private sector organizations would provide greater levels of organizational support for EBPs leading to more positive provider attitudes towards EBPs and EBP use. We also expected attitudes toward EBPs to mediate the association of organizational support and EBP use. Methods Participants were mental health service providers from 17 communities in 16 states in the United States (n = 170. Path analyses were conducted to compare three theoretical models of the impact of organization type on organizational support for EBP and of organizational support on provider attitudes toward EBP and EBP use. Results Consistent with our predictions, private agencies provided greater support for EBP implementation, and staff working for private agencies reported more positive attitudes toward adopting EBPs. Organizational support for EBP partially mediated the association of organization type on provider attitudes toward EBP. Organizational support was significantly positively associated with attitudes toward EBP and EBP use in practice. Conclusion This study offers further support for the importance of organizational context as an influence on organizational support for EBP and provider attitudes toward adopting EBP. The study demonstrates the role organizational support in provider use of EBP in practice. This study also suggests that organizational support for innovation is a malleable factor in supporting use of EBP. Greater attention should be paid to organizational influences that can facilitate the dissemination and implementation of EBPs in
All astronomical sources are polarized to some degree. Polarimetry is therefore a powerful astronomical technique. It furnishes unique diagnostics of e.g. magnetic fields and scattering media. This thesis presents new polarimetric concepts, instruments, and measurements targeting astronomical

Measuring scientific development is a difficult task. Different metrics have been put forward to evaluate scientific development; in this paper we explore a metric that uses the number of peer-reviewed, and when available non-peer-reviewed, research articles as an indicator of development in the field of astronomy. We analyzed the available publication record, using the Smithsonian Astrophysical Observatory/NASA Astrophysics Database System, by country affiliation in the time span between 1950 and 2011 for countries with a gross national income of less than 14,365 USD in 2010. This represents 149 countries. We propose that this metric identifies countries in ''astronomical development'' with a culture of research publishing. We also propose that for a country to develop in astronomy, it should invest in outside expert visits, send its staff abroad to study, and establish a culture of scientific publishing. Furthermore, we propose that this paper may be used as a baseline to measure the success of major international projects, such as the International Year of Astronomy 2009.

To assess the practice of post-abortion family planning (PAFP) counselling among Chinese abortion service providers, and identify the influencing factors. A cross-sectional questionnaire survey was conducted between July and September 2013 among abortion services providers in 30 provinces in China. Univariate and multivariable logistic regression analyses were used to identify the factors that influenced PAFP counselling. 94% of the 579 service providers responded to the questionnaire in the survey. The median age was 39 years (range 20-72), and 95% were females. 92% providers showed a positive attitude and had promoted the PAFP counselling services; however, only 57% spent more than 10 min for it. The overall knowledge on PAFP was limited to the participants. After adjusting for potential confounding factors: providers from the middle region (compared with 'east region', ORadj = 3.33, 95% CI: 2.12-5.21) conducted more PAFP counseling; providers with more knowledge (ORadj = 2.08, 95% CI: 1.38-3.15) provided more counseling; and compared with 'middle school and below', providers with higher education gave more counseling [ORadj(95% CI)] for 'college', 'university' and 'master/doctor' [1.99 (1.01,3.92), 2.32 (1.22,4.40) and 2.34 (1.06,5.17), respectively]. The majority of providers could provide PAFP counselling to women undergone an abortion, but some of them had insufficient time to make it available. Education, knowledge about fertility and reproductive health and residence region were the main factors influencing the practice. Training of health providers and integrating family planning as a part of abortion services are essential to provide adequate PAFP to abortion seekers, thereby reducing the risk of unintended pregnancy.

The Instrument Remote Control (IRC) project ongoing at NASA's Goddard Space Flight Center's (GSFC) Information Systems Center (ISC) supports NASA's mission by defining an adaptive intranet-based framework that provides robust interactive and distributed control and monitoring of remote instruments. An astronomical IRC architecture that combines the platform-independent processing capabilities of Java with the power of Extensible Markup Language (XML) to express hierarchical data in an equally platform-independent, as well as human readable manner, has been developed. This architecture is implemented using a variety of XML support tools and Application Programming Interfaces (API) written in Java. IRC will enable trusted astronomers from around the world to easily access infrared instruments (e.g., telescopes, cameras, and spectrometers) located in remote, inhospitable environments, such as the South Pole, a high Chilean mountaintop, or an airborne observatory aboard a Boeing 747. Using IRC's frameworks, an astronomer or other scientist can easily define the type of onboard instrument, control the instrument remotely, and return monitoring data all through the intranet. The Astronomical Instrument Markup Language (AIML) is the first implementation of the more general Instrument Markup Language (IML). The key aspects of our approach to instrument description and control applies to many domains, from medical instruments to machine assembly lines. The concepts behind AIML apply equally well to the description and control of instruments in general. IRC enables us to apply our techniques to several instruments, preferably from different observatories.

The US Preventive Services Task Force (USPSTF) recommends offering or referring adults who are overweight or obese and have additional cardiovascular disease (CVD) risk factors to intensive behavioral counseling interventions to promote a healthful diet and physical activity for CVD prevention. This study determined the proportion of primary care providers (PCPs) who discussed physical activity with most of their at-risk patients and referred them to intensive behavioral counseling, and reported barriers to counseling. Our analyses used data from DocStyles 2015, a Web-based panel survey of 1251 PCPs. Overall, 58.6% of PCPs discussed physical activity with most of their at-risk patients. Among these PCPs, the prevalence of components offered ranged from 98.5% encouraging increased physical activity to 13.9% referring to intensive behavioral counseling. Overall, only 8.1% both discussed physical activity with most at-risk patients and referred to intensive behavioral counseling. Barriers related to PCPs' attitudes and beliefs about counseling (e.g., counseling is not effective) were significantly associated with both discussing physical activity with most at-risk patients and referring them to intensive behavioral counseling (adjusted odds ratio, 1.92; 95% confidence interval, 1.15-3.20). System-level barriers (e.g., referral services not available) were not. Just over half of PCPs discussed physical activity with most of their at-risk patients, and few both discussed physical activity and referred patients to intensive behavioral counseling. Overcoming barriers related to attitudes and beliefs about physical activity counseling could help improve low levels of counseling and referrals to intensive behavioral counseling for CVD prevention.

The astronomical Virtual Observatory (VO) aims at providing seamless access to the wealth of the discipline's on-line resources, hence at developing global interoperability between them. This is coordinated by the International Virtual Observatory Alliance (IVOA). The paper summarizes the VO history and current evolution. During the first period of VO development, a huge amount of work has been devoted to the development of basic interoperability standards, to set up the VO framework for publication of data and for tools interoperability. This has proven to be a major asset for seamless usage of data. Now the VO is in operation, and the emphasis on supporting the take-up by astronomers and data providers, as well as on outreach, is increasing. A census of European astronomical data centres performed in 2009/2010 shows a large interest in the VO, and a wide diversity of sizes and organisations, in the data centre community. The different strands of work of an operational VO, and the challenges ahead are described, taking in particular the example of the European VO. The European implementation of the VO has been moulded by the specific organisation of European astronomy, with complementary roles of the national and European levels. Local and national projects contribute to the VO development and implementation in their domains of interest and expertise. Several projects supported by the European Commission have helped to shape Euro-VO, with a strong emphasis on coordination of national and intergovernmental agency projects, with actions towards astronomers, data centres and VO developers, including during the last period of outreach towards education and the public. The Astronet Infrastructure Roadmap for European astronomy (2009) has recognized data and the VO as one of the infrastructures of astronomy. The way forward in this context is discussed. In conclusion, the astronomical data infrastructure is put in perspective with the general trends around scientific

The Observatoire de Paris is offering a partnership between teachers and astronomers. The principle is simple: any teacher wishing to undertake a pedagogical project in astronomy, in the classroom or involving the entire school, can request the help of a mentor. An astronomer from the Observatoire de Paris will then follow the teacher's project progress and offer advice and scientific support throughout the school year. The projects may take different forms: construction projects (models, instruments), lectures, posters, exhibitions, etc. The type of assistance offered is as varied as the projects: lecture(s) in class, telephone and e-mail exchanges, visits to the Observatoire; an almost made-to-measure approach that delighted the thirty or so groups that benefited such partnership in the 2005-2006 academic year. And this number is continuously growing. There was a rich variety of projects undertaken, from mounting a show and building a solar clock to visiting a high altitude observatory, or resolving the mystery of Jupiter's great red spot. The Universe and its mysteries fascinate the young (and the not so- young) and provide a multitude of scientific topics that can be exploited in class. Astronomy offers the added advantage of being a multidisciplinary field. Thus, if most projects are generally initiated by a motivated teacher, they are often taken over by teachers in other subjects: Life and Earth Sciences (SVT), history, mathematics, French, and so forth. The project may consist in an astronomy workshop or be part of the school curriculum. Whatever the case, the astronomer's task is not to replace the teacher or the textbooks, but to propose activities or experiments that are easy to implement. Representing the Solar system on a school-yard scale, for instance, is a perfect way to make youngsters realize that the Universe consists mostly of empty space. There is no shortage of topics, and the students' enthusiasm, seldom absent, is the best reward for the
Mesoamerican civic and ceremonial buildings were largely oriented to astronomical phenomena on the horizon, mostly to sunrises and sunsets on particular dates; some orientations were probably intended to mark major lunar standstills and Venus extremes. Solar orientations must have had a practical function, allowing the use of observational calendars that facilitated a proper scheduling of agricultural activities. Moreover, some important buildings seem to have been erected on carefully selected places, with the purpose of employing prominent peaks on the local horizon as natural markers of sunrises and sunsets on relevant dates. However, the characteristics of buildings incorporating deliberate alignments, their predominant clockwise skew from cardinal directions, and their relations to the surrounding natural and cultural landscape reveal that the architectural and urban planning in Mesoamerica was dictated by a complex set of rules, in which astronomical considerations were embedded in a broader framework of cosmological concepts substantiated by political ideology.

Introducton: Kidney stone recurrence is common. Preventive measures can lead to improved quality of life and costs savings to the individual and healthcare system. Guidelines to prevent recurrent kidney stones are published by various urological societies. Adherence to guidelines amongst healthcare professionals in general is poor, while adherence to preventive management guidelines regarding stone disease is unknown. To understand this issue, we conducted an online study to assess the knowledge, attitudes, and practice patterns of healthcare practitioners in Northern Ontario. Methods: We used the database of healthcare providers affiliated with the Northern Ontario School of Medicine, in Sudbury (East Campus) and Thunder Bay (West Campus), Ontario. We designed the survey based on current best practice guidelines for the management of recurrent kidney stones. Questions covered 3 domains: knowledge, attitudes, and practice patterns. Demographic data were also collected. The survey was distributed electronically to all participants. Results: A total of 68 healthcare providers completed the survey. Of these, most were primary care physicians (72%). To keep uniformity, we analyzed the data of this homogenous group. A total of 70% of the respondents were aware of the current guidelines; however, only 43% applied their knowledge in clinical practice. Most participants lacked confidence while answering most items in the attitude domain. Conclusions: Most primary care physician respondents were aware of the appropriate preventive measures for recurrent kidney stones; however, they do not appear to apply this knowledge effectively in clinical practice. A low response rate is a limitation of our study. Further studies involving a larger sample size may lead to information sharing and collaborative care among healthcare providers. PMID:25485006

To determine primary care providers' rates of screening for suicide and mental health problems in adolescents and the factors that promote or discourage this practice. Overall, 671 medical professionals (ie, pediatricians, family physicians, nurse practitioners, physician assistants) completed an electronic survey. The 53 items focused on (1) attitudes, knowledge, and comfort with general psychosocial and suicide screening and (2) current practices and barriers regarding screening and referrals to behavioral health services. Forty percent had a patient attempt suicide in the past year, and 7.7% had 6 or more patients attempt suicide. At a well visit, 67% screened for mental health, and 35.2% screened for suicide risk. Most (61.1%) primary care providers rarely screened for suicide or only when it was indicated. Only 14.2% of primary care providers often used a standardized suicide screening tool. Factors associated with screening were being knowledgeable about suicide risk, being female, working in an urban setting, and having had a suicidal patient. Only 3.0% reported adequate compensation for these practices, and 44% agreed that primary care providers frequently use physical health billing codes for behavioral health services. Nearly 90% said parent involvement was needed if adolescents were to follow through with referrals to mental health services. Only 21% frequently heard back from the behavioral health providers after a referral was made. Policy that promotes mental health education for primary care providers, provides reimbursement for mental health screening, and encourages better service integration could increase suicide screening and save healthcare costs and patients' lives.

This paper analyzes the astronomical background of the global huge earthquakes with M≥8.5. The result shows that most of the earthquakes has occurred in the seismic belts (regions) where is being corresponding seismic active period with the lunar path, solar active falling period and accelerating period of earth rotation. This is as for the variation of long period of astronomical factors. For the variation of short period of astronomical factors, whether for local time or local sidereal time and lunar phase there is the phenomenon of occurrence of concentrating a interval time for the earthquakes. For the short variation of earth rotation this phenomenon is clear; either the earthquakes occur in most fast or in lowest of earth rotation. The above-mentioned results indicate that the eartquakes occurrence is affected by astronomical factors. The astronomical factors are one of motive force causing earthquake from external world. The astronomical factors with long period may act as modulation for the earthquake-pregnant process. And the astronomical factors with short period will causing huge fluctuations of the system and earthquake occur when it act on seismic structure of away from balance state.

Despite the elevated rates of teen and unplanned pregnancies across the United States, long-acting reversible contraceptives (LARCs) remain a less utilized birth control method. The present study investigated family planning providers' attitudes and considerations when recommending family planning methods and LARCs to clients. Additionally, this study explored whether urban-rural differences exist in providers' attitudes toward LARCs and in clients' use of LARCs. Data were collected using an online survey of family planning providers at Title X clinics in Texas. Survey data was linked to family planning client data from the Family Planning Annual Report (2008). Findings indicated that, although providers were aware of the advantages of LARCs, clients' LARC use remains infrequent. Providers reported that the benefits of hormone implants include their effectiveness for 3 years and that they are an option for women who cannot take estrogen-based birth control. Providers acknowledged the benefits of several types of LARCs; however, urban providers were more likely to acknowledge the benefits of hormone implants compared with their rural counterparts. Results also indicated barriers to recommending LARCs, such as providers' misinformation about LARCs and their caution in recommending LARCs to adolescents. However, findings also indicated providers lack training in LARC insertion, specifically among those practicing in rural areas. In light of the effectiveness and longevity of LARCs, teenagers and clients living in rural areas are ideal LARC candidates. Increased training among family planning providers, especially for those practicing in rural areas, may increase their recommendations of LARCs to clients. Copyright © 2012 Jacobs Institute of Women

We investigate religious myths related to astronomy from different cultures in an attempt to identify common subjects and characteristics. The paper focuses on astronomy in religion. The initial review covers records from Holy books about sky related superstitious beliefs and cosmological understanding. The purpose of this study is to introduce sky related religious and national traditions (particularly based on different calendars; Solar or Lunar). We carried out a comparative study of astronomical issues contained in a number of Holy books: Ancient Egyptian Religion (Pyramid Texts), Zoroastrianism (Avesta), Hinduism (Vedas), Buddhism (Tipitaka), Confucianism (Five Classics), Sikhism (Guru Granth Sahib), Christianity (Bible), Islam (Quran), Druidism (Mabinogion) and Maya Religion (Popol Vuh). These books include various information on the creation of the Universe, Sun and Moon, the age of the Universe, Cosmic sizes, understanding about the planets, stars, Milky Way and description of the Heavens in different religions. We come to the conclusion that the perception of celestial objects varies from culture to culture, and from religion to religion and preastronomical views had a significant impact on humankind, particularly on religious diversities. We prove that Astronomy is the basis of cultures, and that national identity and mythology and religion were formed due to the special understanding of celestial objects.

This study aimed to assess knowledge, attitude and practice related to consanguinity among multiethnic health care providers in the Kingdom of Saudi Arabia. Using a cross-sectional study design, a validated, self-administered close-ended questionnaire was randomly distributed to health care providers in different health institutions in the country between 1st August 2012 and 31st July 2013. A total of 1235 health care providers completed the study questionnaire. Of the 892 married participants (72.23% of total), 11.43% were married to a first cousin, and were predominantly Arabs, younger than 40 years and male. Only 17.80% of the patients seen by the health care providers requested consanguinity related counselling. A knowledge barrier was expressed by 27.49% of the participants, and 85.67% indicated their willingness to have more training in basic genetic counselling. A language barrier was expressed as a limiting factor to counselling for consanguinity among non-Arabs. The health care providers had a major dearth of knowledge that was reflected in their attitude and practice towards consanguinity counselling. This finding indicates the need for more undergraduate and postgraduate medical and nursing education and training in the counselling of consanguineous couples. It is recommended that consanguinity counselling is included in the current premarital screening and counselling programmes in the Kingdom.

The burden of chronic wounds is substantial, and this burden is set to increase as the population ages. The challenge for community health services is significant. Wound care is labour intensive, and demand for services is set to increase at a time when the availability of nursing resources is likely to be severely limited. In March 2005, the Niagara community health care provider implemented a radical reorganisation of wound management practices designed to ensure that available resources, particularly nurse time, were being used in the most efficient way. An evaluation of the impact of the reorganisation has shown improvements in clinical practice and better patient outcomes. The use of traditional wound care products reduced from 75% in 2005 to 20% in 2007 in line with best practice recommendations, and frequency of daily dressing changes reduced from 48% in 2005 to 15% in 2007. In a comparison of patients treated in 2005 and 2006, average time to healing was 51.5 weeks in 2005 compared with 20.9 weeks in 2006. Total treatment cost was lower in 2006 by $10,700 (75%) per patient. Overall, improvements in wound management practice led to a net saving of $3.8 million in the Niagara wound care budget.
different forms of astronomical heritage, including its intangible aspects, that will help in the development of more integrated approaches to identification and cataloguing, protection and preservation; and 3. to increase global awareness of regional, national and local initiatives relating to astronomical heritage in all its forms. In pursuance of these aims, the meeting also recommended that the AWHWG, working in collaboration with the WGs on Astronomical Instruments and Archives, and other bodies as appropriate, should develop the following additional projects: 1. to establish guidelines to help in the identification and safeguarding of tangible and intangible astronomical heritage in all its forms; 2. to gather examples of existing best practice, and to make these available as case studies on their website; and 3. to develop the website of the Astronomy and World Heritage Initiative (AWHI) as a portal to existing on-line catalogues and thesauri. It also recommended that the WGs should work together to: 1. formulate recommendations about the ways in which links and common approaches should be developed in the future; and 2. organise a meeting of international experts in the historical and heritage aspects of astronomical structures, instruments, and archives, focussed specifically upon the task of developing more integrated approaches to identification and cataloguing, protection and preservation. This joint session will attempt to make headway on as many as possible of these issues. In this opening talk I will attempt to lay out some of the main challenges that we face, and outline what we hope to achieve in this session.

Care coordination programmes are an important aspect of HIV management whose success depends largely on HIV primary care provider (PCP) and case manager collaboration. Factors influencing collaboration among HIV PCPs and case managers remain to be studied. The study objective was to test an existing theoretical model of interprofessional collaborative practice and determine which factors play the most important role in facilitating collaboration. A self-administered, anonymous mail survey was sent to HIV PCPs and case managers in New York City. An adapted survey instrument elicited information on demographic, contextual, and perceived social exchange (trustworthiness, role specification, and relationship initiation) characteristics. The dependent variable, perceived interprofessional practice, was constructed from a validated scale. A sequential block wise regression model specifying variable entry order examined the relative importance of each group of factors and of individual variables. The analysis showed that social exchange factors were the dominant drivers of collaboration. Relationship initiation was the most important predictor of interprofessional collaboration. Additional influential factors included organisational leadership support of collaboration, practice settings, and frequency of interprofessional meetings. Addressing factors influencing collaboration among providers will help public health programmes optimally design their structural, hiring, and training strategies to foster effective social exchanges and promote collaborative working relationships.
Full Text Available BACKGROUND: Neurological disorders of infectious origin are common in rural sub-Saharan Africa and usually have serious consequences. Unfortunately, these syndromes are often poorly documented for lack of diagnostic tools. Clinical management of these diseases is a major challenge in under-equipped rural health centers and hospitals. We documented health care provider knowledge, attitudes and practices related to this syndrome in two rural health zones in Bandundu Province, Democratic Republic of Congo. METHODS: We used a qualitative research approach combining observation, in-depth interviews and focus group discussions. We observed 20 patient-provider contacts related to a neurological syndrome, conducted 12 individual interviews and 4 focus group discussions with care providers. All interviews were audiotaped and the transcripts were analyzed with the software ATLAS.ti. RESULTS: Care providers in this region usually limit their diagnostic work-up to clinical examination primarily because of the financial hurdles in this entirely out-of-pocket payment system. The patients prefer to purchase drugs rather than diagnostic tests. Moreover the general lack of diagnostic tools and the representation of the clinician as a "diviner" do not enhance any use of laboratory or other diagnostic methods. CONCLUSION: Innovation in diagnostic technology for neurological disorders is badly needed in Central-Africa, but its uptake in clinical practice will only be a success if tools are simple, affordable and embedded in a patient-centered approach.

Full Text Available Abstract Background Knowledge, attitudes and practices of community members and healthcare providers in rural northern Ghana regarding clean delivery are not well understood. This study explores hand washing/use of gloves during delivery, delivering on a clean surface, sterile cord cutting, appropriate cord tying, proper cord care following delivery, and infant bathing and cleanliness. Methods In-depth interviews and focus group discussions were audiotaped, transcribed, and analyzed using NVivo 9.0. Results 253 respondents participated, including women with newborn infants, grandmothers, household and compound heads, community leaders, traditional birth attendants, and formally trained health care providers. There is widespread understanding of the need for clean delivery to reduce the risk of infection to both mothers and their babies during and shortly after delivery. Despite this understanding, the use of gloves during delivery and hand washing during and after delivery were mentioned infrequently. The need for a clean delivery surface was raised repeatedly, including explicit discussion of avoiding delivering in the dirt. Many activities to do with cord care involved non-sterile materials and practices: 1 Cord cutting was done with a variety of tools, and the most commonly used were razor blades or scissors; 2 Cord tying utilized a variety of materials, including string, rope, thread, twigs, and clamps; and 3 Cord care often involved applying traditional salves to the cord - including shea butter, ground shea nuts, local herbs, local oil, or “red earth sand.” Keeping babies and their surroundings clean was mentioned repeatedly as an important way to keep babies from falling ill. Conclusions This study suggests a widespread understanding in rural northern Ghana of the need for clean delivery. Nonetheless, many recommended clean delivery practices are ignored. Overarching themes emerging from this study included the increasing use of

Ring resonators provide a means of filtering specific wavelengths from a waveguide, and optionally dropping the filtered wavelengths into a second waveguide. Both of these features are potentially useful for astronomical instruments. In this paper we focus on their use as notch filters to remove the signal from atmospheric OH emission lines from astronomical spectra. We derive the design requirements for ring resonators for OH suppression from theory and finite difference time domain simulations. We find that rings with small radii (< 10 μm) are required to provide an adequate free spectral range, leading to high index contrast materials such as Si and Si3N4. Critically coupled rings with high self-coupling coefficients should provide the necessary Q factors, suppression depth, and throughput for efficient OH suppression, but will require post-inscription tuning of the coupling and the resonant wavelengths. The overall prospects for the use of ring resonators in astronomical instruments is promising, provided efficient fibre-chip coupling can be achieved.

The Pro-Am Collaborative Astronomy (PACA) project evolved from the observational campaign of C/2012 S1 or C/ISON in 2013. Following the success of the professional-amateur astronomer collaboration in scientific research via social media, it is now implemented in other comet observing campaigns. While PACA identifies a consistent collaborative approach to pro-am collaborations, given the volume of data generated for each campaign, new ways of rapid data analysis, mining access and storage are needed. Several interesting results emerged from the synergistic inclusion of both social media and amateur astronomers: (1) the establishment of a network of astronomers and related professionals, that can be galvanized into action on short notice to support observing campaigns; (2) assist in various science investigations pertinent to the campaign; (3) provide an alert-sounding mechanism should the need arise; (4) immediate outreach and dissemination of results via our media/blogger members; (5) provide a forum for discussions between the imagers and modelers to help strategize the observing campaign for maximum benefit. In 2014, two new comet observing campaigns involving pro-am collaborations have been initiated: (1) C/2013 A1 (C/SidingSpring) and (2) 67P/Churyumov-Gerasimenko (CG), target for ESA/Rosetta mission. The evolving need for individual customized observing campaigns has been incorporated into the evolution of PACA portal that currently is focused on comets: from supporting observing campaigns of current comets, legacy data, historical comets; interconnected with social media and a set of shareable documents addressing observational strategies; consistent standards for data; data access, use, and storage, to align with the needs of professional observers. The integration of science, observations by professional and amateur astronomers, and various social media provides a dynamic and evolving collaborative partnership between professional and amateur astronomers

The adoption of evidence-based practice (EBP) is promoted because it is widely recognized for improving the quality and safety of health care for patients, and reducing avoidable costs. Providers of primary care face numerous challenges to ensuring the effectiveness of their daily practices. Primary health care is defined as: the entry level into a health care services system, providing a first point of contact for all new needs and problems; patient-focused (not disease-oriented) care over time; care for all but the most uncommon or unusual conditions; and coordination or integration of care, regardless of where or by whom that care is delivered. Primary health care is the principal means by which to approach the main goal of any health care services system: optimization of health status. This review aims to scope publications examining beliefs, knowledge, implementation, and integration of EBPs among primary health care providers (HCPs). We will conduct a systematic scoping review of published articles in the following electronic databases, from their start dates until March 31, 2017: Medical Literature Analysis and Retrieval System Online (MEDLINE) via PubMed (from 1946), Embase (from 1947), Cumulative Index to Nursing and Allied Health Literature (CINAHL; from 1937), the Cochrane Central Register of Controlled Trials (CENTRAL; from 1992), PsycINFO (from 1806), Web of Science (from 1900), Joanna Briggs Institute (JBI) database (from 1998), Database of Abstracts of Reviews of Effects (DARE; from 1996), Trip medical database (from 1997), and relevant professional scientific journals (from their start dates). We will use the predefined search terms of, "evidence-based practice" and, "primary health care" combined with other terms, such as, "beliefs", "knowledge", "implementation", and "integration". We will also conduct a hand search of the bibliographies of all relevant articles and a search for unpublished studies using Google Scholar, ProQuest, Mednar, and World

Health care providers are often ill prepared to interact about or make acceptable conclusions on complementary and alternative medicine (CAM) despite its widespread use. We explored the knowledge, attitudes, and practices of health care providers regarding CAM. This cross-sectional study was conducted between March 1 and July 31, 2015 among health care providers working mainly in the public sector in Trinidad and Tobago. A 34-item questionnaire was distributed and used for data collection. Questionnaire data were analysed using inferential and binary logistic regression models. Response rate was 60.3% (362/600). Responders were 172 nurses, 77 doctors, 30 pharmacists, and 83 other health care providers of unnamed categories (mainly nursing assistants). Responders were predominantly female (69.1%), Indo-Trinidadian (55.8%), Christian (47.5%), self-claimed "very religious" (48.3%), and had alternative, and physical types of CAM, but had no knowledge of energy therapy and therapeutic methods. Sex, ethnicity, and type of health care provider were associated with both personal use and recommendation for the use of CAM. Predictors of CAM use were sex, religion, and type of health care provider; predictors of recommendation for the use of CAM were sex and type of health care provider. About half of health care providers (51.4%) and doctors (52%) were likely to ask their patients about CAM and medicine alone. Less than 10% said conventional medicine should be used alone. Knowledge about CAM is low among health care providers. The majority engages in using CAM but is reluctant to recommend it. Predictors of CAM use were sex, religion, and profession; predictors of recommendation for the use of CAM were sex and profession. Health care providers feel the future lies in integrative medicine.

Clinical trials play an important role in the generation of evidence-based data in health care practices. To ensure the credibility of data and the safety and well-being of the patients Good clinical practice (GCP) guidelines play an important role. At present, we have little knowledge about awareness of GCP guidelines among health care providers in India. To assess the level of awareness, and perception of the health care providers toward GCP and subsequent change in these after a dayer training session on GCP guidelines. A cross-sectional descriptive questionnaire-based study was conducted amongst health care providers, that is, doctors, dentists, nurses of a Tertiary Health Care and Teaching Institute. Participants were given descriptive questionnaire; they completed the questionnaire before and after undergoing a day training program in GCP guidelines. The impact of the effectiveness of educational intervention among healthcare professionals was evaluated by two-tailed Z-test. Out of 120 participants, 80 were medical doctors, 20 dental doctors, and 20 nurses. A dayse training program on GCP guidelines was found to increase positive attitudes toward various aspects of clinical trials. A day's training program on GCP guidelines may help to increase the knowledge as well as awareness about principles and techniques of clinical research, which will increase the credibility of clinical research in the country.

This study examined influences of causal attributions of schizophrenia and perceived and internalized mental illness stigma on perceived working alliance with, and informational support received from doctors practicing Western psychiatry in the Taiwanese social-cultural context. This cross-sectional quantitative study used a non-probability, purposive sampling technique to recruit 212 Taiwanese diagnosed with schizophrenia from Taiwanese Alliance of the Mentally Ill, 4 community mental health rehabilitation centres and 2 psychiatric hospitals between July 2012 and March 2013. Linear regression models were used for analysis. The results showed that environmental attributions were positively associated with both perceived working alliance and perceived informational support, while supernatural attributions were negatively associated with perceived working alliance and perceived informational support. Perceived stigma had a negative association with perceived working alliance. The discrimination domain of internalized stigma specifically had a positive association with perceived working alliance, while the withdraw domain had a negative association with perceived informational support. Findings inform the importance of culturally sensitive practices in developing an effective working relationship. Western psychiatric care providers need to explore consumers' casual attributions of mental illness and understand the impact of stigma so that providers may successfully engage consumers in care and provide tailored illness education and information.

Fetal Alcohol Spectrum Disorder (FASD) is an umbrella term that describes the range of effects that can occur in an individual who was prenatally exposed to alcohol and includes an array of complex neurodevelopmental and physical findings. To give primary healthcare providers (PHCP) evidence-based recommendations for supporting and managing the symptoms of FASD after patients have received a diagnosis. MethodsPrimary health recommendations for the management of children and adolescents with FASD were developed based on expert clinical judgment and supported by evidence-based research, where appropriate. The format was adapted from other health supervision practice guidelines as developed by the American Academy of Pediatrics. Clinical practice "Points" for the PHCP are highlighted. A reference table of anticipatory recommendations by age is presented. In most cases, the initial screening and referral for diagnosis will be made by the PHCP, and they will be responsible for ongoing management. It is anticipated that these recommendations will provide the PHCP with evidence to support the longitudinal health care of children and adolescents with FASD and their families as they transition throughout all developmental stages. There is a pressing need for the involvement of PHCP in the active care of children and adolescents with FASD and their families over the lifespan. PHCP are trained in screening, prevention, and management of health needs, and are in the position to coordinate sub-specialty referrals as needed. Engaging PHCP will provide a truly integrated care system for individuals with FASD and their families.

Adolescents are at risk for pregnancy, sexually transmitted diseases, suicide, homicide, accidents, and substance abuse. Adolescent medicine involves an overlap of many skills needed to provide routine medical care, as well as care for those conditions that require psychosocial assessment. We report the results of a mail survey covering care of this age group by practitioners of pediatrics, internal medicine, obstetrics and gynecology, family practice, and adolescent medicine in a large, multispecialty, prepaid group practice. The mail survey covered 10 areas of adolescent care. Adolescent medicine physicians expressed the highest level of perceived knowledge and competence in these areas, with family practitioners ranked second. More than 50% of internists and pediatricians felt only fair to poor competence for a variety of adolescent conditions, whereas a third of internists and pediatricians reported that they liked to care for adolescents. Physicians in all 4 of the primary care specialties reported a need for a teen health center for both consultation and education. These results are similar to those reported for pediatricians and primary care physicians in private practice and for residents in internal medicine. PMID:1615655

Quality assurance is an indispensable element in a molecular diagnostic laboratory. The ultimate goal is to warrant patient safety. Several risks that can compromise high quality procedures are at stake, from sample collection to the test performed by the laboratory, the reporting of test results to clinicians, and the organization of effective external quality assessment schemes. Quality assurance should therefore be safeguarded at each level and should imply a holistic multidisciplinary approach. This review aims to provide an overview of good quality assurance practices and discusses certain risks and recommendations to promote and improve quality assurance for both diagnostic laboratories and for external quality assessment providers. The number of molecular targets is continuously rising, and new technologies are evolving. As this poses challenges for clinical implementation and increases the demand for external quality assessment, the formation of an international association for improving quality assurance in molecular pathology is called for.
(Abstract only) The capability of small aperture astronomical instrumentation systems (AIS) to make meaningful scientific contributions has never been better. The purpose of AIS quality management planning (AISQMP) is to ensure the quality of these contributions such that they are both valid and reliable. The first step involved with AISQMP is to specify objective quality measures not just for the AIS final product, but also for the instrumentation used in its production. The next step is to set up a process to track these measures and control for any unwanted variation. The final step is continual effort applied to reducing variation and obtaining measured values near optimal theoretical performance. This paper provides an overview of AISQMP while focusing on objective quality measures applied to astronomical imaging systems.

Large experimental facilities, like telescopes and focal plane instrumentation in the astronomical domain, are becoming more and more complex and expensive, as well as control systems for managing such instruments. The general trend, as can be learned by realizations carried out in the most recent years, clearly drives to most cost-effective solutions: widespread, stable standards in the software field, COTS (commercial off-the-shelf) components and industry standards in the hardware field. Therefore a new generation of control system products needs to be developed, in order to help the scientific community to minimize the cost and efforts required for maintenance and control of their facilities. In the spirit of the aforementioned requirements and to provide a low-cost software and hardware environment we present a working prototype of a control system, based on RTAI Linux and on ACS (Advanced Control System) framework ported to an embedded platform. The hardware has been chosen among COTS components: a PC/104+ platform equipped with a PMAC2A motion controller card and a commercial StrongARM single board controller. In this way we achieved a very powerful, inexpensive and robust real-time control system which can be used as a general purpose building block in the design of new instruments and could also be proposed as a standard in the field.

Model Based Systems Engineering (MBSE) is an emerging field of systems engineering for which the System Modeling Language (SysML) is a key enabler for descriptive, prescriptive and predictive models. This paper surveys some of the capabilities, expectations and peculiarities of tools-assisted MBSE experienced in real-life astronomical projects. The examples range in depth and scope across a wide spectrum of applications (for example documentation, requirements, analysis, trade studies) and purposes (addressing a particular development need, or accompanying a project throughout many - if not all - its lifecycle phases, fostering reuse and minimizing ambiguity). From the beginnings of the Active Phasing Experiment, through VLT instrumentation, VLTI infrastructure, Telescope Control System for the E-ELT, until Wavefront Control for the E-ELT, we show how stepwise refinements of tools, processes and methods have provided tangible benefits to customary system engineering activities like requirement flow-down, design trade studies, interfaces definition, and validation, by means of a variety of approaches (like Model Checking, Simulation, Model Transformation) and methodologies (like OOSEM, State Analysis)

A questionnaire survey was conducted to determine the worm control practices and anthelmintic usage of 150 key respondents involved in sheep and goat production in the arid Thal area of Pakistan. The information was collected by visiting farms, and interviewing the key respondents which included veterinary officers (n = 15), veterinary assistants (n = 51), traditional practitioners (n = 24), and small and large scale sheep/goat farm herders and owners (n = 60). Among all interviewed animal healthcare providers, the veterinary officers had the highest level of awareness of parasitic infection and advocated the use of modern available anthelmintics according to the predefined schedule. The farmers on the other hand, had the lowest level of knowledge about parasitic infections. They used modern anthelmintics at low frequencies (every six months) following an unusual practice of diluting the medicine. Veterinary assistants had a medium level of awareness about the parasitic infections using anthelmintic treatments when they deemed necessary rather than following a predefined treatment schedule. Traditional practitioners were also aware of parasitic infections and used traditional anthelmintics or a combination of the traditional and modern anthelmintics. The animal health providers had a different awareness and knowledge of parasitic infections which resulted in contrasting proposals for its' control. The farmers used worm control measures in accordance with their own views and those of animal healthcare advisors, combining modern and traditional treatments. This study provides the first insight into the differing views of those animal healthcare providers who form the basis for effective parasitic control within the sheep and goat industry of an arid region.

(Abstract only) This past year has seen a marked increase in amateur astronomer participation in exoplanet research. This has ranged from amateur astronomers helping professional astronomers confirm candidate exoplanets, to helping refine the ephemeris of known exoplanets. In addition, amateur astronomers have been involved in characterizing such exotic objects as disintegrating planetesimals. However, the involvement in such pro/am collaborations has also required that amateur astronomers follow a more disciplined approach to exoplanet observing.

Science and literature, two means of inquiry now thought in opposition (if not posed as outright contradiction) emerged for a moment in the nineteenth century as provocatively complimentary in their methods of reading. In America, astronomy in particular provided a rich, complex subject for writers of the imagination to think about in terms of content and methodology. The purpose of my study is to uncover these unacknowledged astronomical referents in the works of Emily Dickinson, Herman Melville, and Edgar Allan Poe, and engage them as interpretive contexts in new readings of their most esoteric projects; specifically, Dickinson's solstice and circumference poetry, the Plinlimmon pamphlet in Melville's Pierre, and Poe's Eureka. After providing historical context through the shared public experience of the 1833 Leonid Meteor Storm, I uncover several astronomical and scientific sources for these writers: Denison Olmsted for Dickinson; Gauss and Plotinus for Melville; and Kepler and Alexander von Humboldt for Poe, among others. Exploring these sources in close readings of their works, I find that these authors employ astronomical facts in very different, metaphorical ways in response to the larger challenge of navigating their own poetics between the emerging new laws of science and the immeasurability of human feeling evoked by the unknown Universe.

The beauty and splendor of astronomical press release images has made an enormously positive impact with the media and public alike. As a leading provider of astronomical imagery and a major contributor of Hubble Space Telescope press release images, the outreach division of Space Telescope Science Institute (STScI) recognizes the importance of making press release images compliant with virtual observatory standards for inclusion in databases and repositories. Our goal is to make outreach images accessible by virtual observatory applications by calculating World Coordinate System (WCS) data for these images. We provide updated and improved software that allows observatories to easily and accurately transform coordinates on their astronomical press release images, using reference FITS files. The resultant metadata conforms to the Simple Image Access (SIA) protocol established by the International Virtual Observatory Alliance and has been used by popular end users such as Google Sky and World Wide Telescope. Several hundred images from the STScI Office of Public Outreach NewsCenter database have been processed, and their coordinates and other relevant metadata are accessible through an SIA-compliant web service.

In 2008 and 2009 Scientific Writing for Young Astronomers (SWYA) Schools were held in Blankenberge (B) under the direction of Christiaan Sterken (FWO-VUB). These two books (EAS publication series, Vol. 49 and 50) reflect the outcome of these Schools. Part 1 contains a set of contributions that discuss various aspects of scientific publication; it includes A&A Editors' view of the peer review and publishing process. A very interesting short paper by S.R. Pottasch (Kapteyn Astronomical Institute, Groningen, and one of the two first Editors-in Chief of A&A) deals with the history of the creation of the journal Astronomy & Astrophysics. Two papers by J. Adams et al. (Observatoire de Paris) discuss language editing, including a detailed guide for any non-native user of the English language. In 2002 the Board of Directors decided that all articles in A&A must be written in clear and correct English. Part 2 consists of three very extensive and elaborated papers by Christiaan Sterken, supplying guidelines to PhD students and postdoctoral fellows to help them compose scientific papers for different forums (journals, proceedings, thesis, etc.). This part is of interest not only for young astronomers but it is very useful for scholars of all ages and disciplines. Paper I "The writing process" (60 pp.) copes with the preparation of manuscripts, with communicating with editors and referees and with avoiding common errors. Delicate problems on authorship, refereeing, revising multi-authored papers etc. are treated in 26 FAQ's.

Abstinence-only education has had little demonstrable impact on teenagers' sexual behaviors, despite significant policy and funding efforts. Given the struggle over resources to improve teenagers' reproductive health outcomes, the views of clinicians serving teenagers at high risk for unintended pregnancy and STDs merit particular attention. In 2005, a qualitative study with 31 clinicians serving low-income, at-risk patients was conducted. A semistructured interview guide was used to ask clinicians about adolescent pregnancy, HIV and STD prevention counseling, and when they include abstinence. Thematic content analysis was used to examine the content of the counseling and the techniques used in different situations. Providers reported offering comprehensive counseling, presenting abstinence as a choice for teenagers, along with information about contraceptives and condoms. Several providers mentioned that with young, sexually inexperienced teenagers, they discuss delaying sexual activity and suggest other ways to be affectionate, while giving information on condoms. Providers explained how they assess whether teenagers feel ready to be sexually active and try to impart skills for healthy relationships. Some described abstinence as giving teenagers a way to opt out of unwanted sexual activity. Many support abstinence if that is the patient's desire, but routinely dispense condoms and contraceptives. Overall, providers did not give abstinence counseling as a rigid categorical concept in their preventive practices, but as a health tool to give agency to teenagers within a harm reduction framework. Their approach may be informative for adolescent policies and programs in the future.
Full Text Available Abstract Background People seek treatment for malaria from a wide range of providers ranging from itinerant drug sellers to hospitals. However, there are lots of problems with treatment provision. Hence, factors influencing treatment provision in hospitals and non-hospitals require further investigation in order to remedy the situation. Objectives To examine the knowledge, pattern of treatment provision and factors influencing the behaviour of hospitals and non-hospitals in the treatment of malaria, so as to identify loci for interventions to improve treatment of the disease. Methods A pre-tested structured questionnaire was used to collect data from 225 providers from hospitals and non-hospitals about their malaria treatment practices and factors that influence their provision of malaria treatment services in south-east Nigeria. The data from hospitals and other providers were compared for systematic differences. Results 73.5% of hospitals used microscopy to diagnose malaria and only 34.5.1% of non-hospitals did (p Conclusion There are many challenges to appropriate provision of malaria treatment services, although challenges are less in hospitals compared to other types of non-hospitals. Improving proper diagnosis of malaria and improving the knowledge of providers about malaria are interventions that could be used to improve malaria treatment provision.

In this presentation we address issues relating to the astronomical heritage of contemporary aboriginal groups and other minorities. We deal specially with intangible astronomical heritage and its particularities. Also, we study (from ethnographic experience with Aboriginal groups, Creoles and Europeans in the Argentine Chaco) the conflicts referring to the different ways in which the natives' knowledge and practice are categorized by the natives themselves, by scientists, state politicians, professional artists and NGOs. Furthermore, we address several cases that illustrate these kinds of conflicts. We aim to analyze the complexities of patrimonial policies when they are applied to practices and representations of contemporary communities involved in power relations with national states and the global system. The essentialization of identities, the folklorization of representations and practices, and the fossilization of aboriginal peoples are some of the risks of applying the label ``cultural heritage'' without a careful consideration of each specific case. In particular we suggest possible ways in which the international scientific community could collaborate to improve the agenda of national states instead of reproducing colonial prejudices. In this way, we aim to contribute to the promotion of respect for ethnic and religious minorities.

Enteral feeding tubes are used in pediatric patients to deliver nutrition, fluids or medications. The literature related to short-term feeding tube (nasogastric [NG], hereafter known as NGT, or orogastric [OGT],) use in pediatric homecare patients is sparse. This descriptive study sought to gather baseline information about these children and how their feeding tubes are managed at home. Specifically, we sought to better understand how the tubes are placed and the method(s) used for tube placement verification. Two surveys were distributed: one to parents and one to homecare providers who have direct patient contact. Responses were obtained from 144 parents and 66 homecare providers. Over half of the children were 12months of age or younger and had a 6 Fr feeding tube. Over 75% (108) had an NGT for 1year or less. Predominantly parents replaced the NGT but a few children self-inserted their tubes. Feeding tube placement was verified by auscultation (44%) or measurement of gastric pH (25%) in the parent's survey. Twenty-six percent of parents indicated they had misplaced an NGT at least once and 35 parents described symptoms of pulmonary misplacement. The homecare provider data indicated auscultation (39%) and pH measurement of gastric contents (28%) to verify NG tube placement location. Study results confirms a need for consistency of practice among health care professionals and in parent education for those children who require NGTs at home. It is troubling that auscultation is still widely used for NGT location confirmation despite practice alerts that warn against its use. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available Abstract Background In 1999, the American Academy of Pediatrics and U.S. Public Health Service recommended suspending the birth dose of hepatitis B vaccine due to concerns about potential mercury exposure. A previous report found that overall national hepatitis B vaccination coverage rates decreased in association with the suspension. It is unknown whether this underimmunization occurred uniformly or was associated with how providers changed their practices for the timing of hepatitis B vaccine doses. We evaluate the impact of the birth dose suspension on underimmunization for the hepatitis B vaccine series among 24-month-olds in five large provider groups and describe provider practices potentially associated with underimmunization following the suspension. Methods Retrospective cohort study of children enrolled in five large provider groups in the United States (A-E. Logistic regression was used to evaluate the association between the birth dose suspension and a child's probability of being underimmunized at 24 months for the hepatitis B vaccine series. Results Prior to July 1999, the percent of children who received a hepatitis B vaccination at birth varied widely (3% to 90% across the five provider groups. After the national recommendation to suspend the hepatitis B birth dose, the percent of children who received a hepatitis B vaccination at birth decreased in all provider groups, and this trend persisted after the policy was reversed. The most substantial decreases were observed in the two provider groups that shifted the first hepatitis B dose from birth to 5–6 months of age. Accounting for temporal trend, children in these two provider groups were significantly more likely to be underimmunized for the hepatitis B series at 24 months of age if they were in the birth dose suspension cohort compared with baseline (Group D OR 2.7, 95% CI 1.7 – 4.4; Group E OR 3.1, 95% CI 2.3 – 4.2. This represented 6% more children in Group D and 9
Full Text Available Despite U.S. mothers’ wide adoption of pumps and bottles to provide human milk (HM to their infants, mothers lack comprehensive, evidence-based guidelines for these practices. Thus, some women use online sources to seek information from each other. We aimed to characterize the information women sought online about pumping. We used data provided by ~25,000 women in an open cohort within a discussion forum about parenting. We examined 543 posts containing questions about providing pumped HM cross-sectionally and longitudinally in three time intervals: prenatal, 0 through 1.5 months postpartum, and 1.5 to 4.5 months postpartum. We used thematic analysis with Atlas.ti to analyze the content of posts. During pregnancy, women commonly asked questions about how and where to obtain pumps, both out-of-pocket and through insurance policies. Between 0–1.5 months postpartum, many mothers asked about how to handle pumped HM to ensure its safety as fed. Between 1.5–4.5 months postpartum, mothers sought strategies to overcome constraints to pumping both at home and at work and also asked about stopping pumping and providing their milk. Women’s questions related to ensuring the safety of pumped HM represent information women need from health professionals, while their questions related to obtaining pumps suggest that women may benefit from clearer guidelines from their insurance providers. The difficulties women face at home and at work identify avenues through which families and employers can support women to meet their goals for providing HM.

Intercalibration between the astronomical and radio-isotopic dating methods provides a means to improving accuracy and reducing uncertainty of an integrated, multi-chronometer geologic timescale. Here we report a high-precision 40Ar/39Ar age for the Fish Canyon sanidine (FCs) neutron fluence...... monitor, by multi-collector noble gas mass spectrometry, through cross-calibration with A1 tephra sanidines (A1Ts) of the direct astronomically tuned Faneromeni section (Crete). The astronomically intercalibrated 40Ar/39Ar age of FCs of 28.172±0.028 Ma (2σ, external errors) is within the uncertainty of......, but more precise (±0.10%) than, the previous 40Ar/39Ar age determined by intercalibration with astronomically tuned tephras from the Melilla Basin (Morocco). Using this proposed age for FCs, combined with measurements using the A1Ts as the neutron fluence monitor, a weighted mean Bishop Tuff 40Ar/39Ar...

Background Harm reduction is a health-centred approach that seeks to reduce the health and social harms associated with high-risk behaviors, such as illicit drug use. The objective of this study is to determine the association between the beliefs of a group of adult, male prisoners in Iran about the transmission of HIV and their high-risk practices while in prison. Methods A cross-sectional study was conducted in 2004. The study population was a random selection of 100 men incarcerated at Rajaei-Shahr prison. The data were collected through a self-administered questionnaire. Focus group discussions were held at the prison to guide the design of the questionnaire. The relationship between components of the Health Belief Model (HBM) and prisoners' risky HIV-related behaviors was examined. Results Calculating Pearson's correlation coefficient, a significant, positive association was found between the benefit component of the HBM and prisoners not engaging in HIV high-risk behaviors. Conclusion Educational harm reduction initiatives that promote the effectiveness of strategies designed to reduce the risk of HIV transmission may decrease prisoners' high-risk behaviors. This finding provides initial support for the Iran prison system's current offering of HIV/AIDS harm reduction programming and suggests the need to offer increased education about the effectiveness of HIV prevention practices.

Conclusion Educational harm reduction initiatives that promote the effectiveness of strategies designed to reduce the risk of HIV transmission may decrease prisoners' high-risk behaviors. This finding provides initial support for the Iran prison system's current offering of HIV/AIDS harm reduction programming and suggests the need to offer increased education about the effectiveness of HIV prevention practices.

A primary goal of many university science courses is to promote understanding of the process of contemporary scientific inquiry. One powerful way to achieve this is for students to explore current research and then interact directly with the leading scientist, the feasibility of which has recently increased dramatically due to free online video communication tools. We report on a program implemented at Dartmouth College in which students connect with a guest astronomer through Skype (video chat). The Skype session is wrapped in a larger activity where students explore current research articles, interact with the astronomer, and then reflect on the experience. The in-class Skype discussions require a small time commitment from scientists (20-30 minutes, with little or no need for preparation) while providing students direct access to researchers at the cutting edge of modern astronomy. We outline the procedures used to implement these discussions, and present qualitative assessments of student's understanding of the process of research, as well as feedback from the guest astronomers.

We present a new software solution, based on Java, which allows to deploy and access astronomical catalogs in relational database form, with their associated data products. It is already used to provide the public VVDS data via VO and manage zCosmos data within the Italian COSMOS community; it is also used as the second generation Web interface to the XMM-LSS master catalog. DART (Database Access and Retrieval Tool) supplies a Web interface which allows to query catalogs, filter data by conditions on the columns values (even complex expressions), view the results and export them in private user files; it is also possible to make simple plots or retrieve the related data products. The software supports access to more than one catalog at a time (e.g. for multi-band usage) either in parallel, or as a couple linked by pre-built correlation tables, or even viewing the result of an identification among several catalogs as a single virtual table. DART has been designed as a general tool capable of accessing any collection of astronomical database tables and related products. It is highly (and easily) customizable editing simple configuration files and (for an increased flexibility specially concerning data product access) populating appropriately a few administrative database tables. It supports ConeSearch, SSA and SIA Virtual Observatory protocols. DART will be soon released to the astronomical community from the PANDORA Web site (http://cosmos.iasf-milano.inaf.it/pandora/dart.html).
Full Text Available Celestial positioning has been used for navigation purposes for many years. Stars as the extra-terrestrial benchmarks provide unique opportunity in absolute point positioning. However, astronomical field data acquisition and data processing of the collected data is very time-consuming. The advent of the Global Positioning System (GPS nearly made the celestial positioning system obsolete. The new satellite-based positioning system has been very popular since it is very efficient and convenient for many daily life applications. Nevertheless, the celestial positioning method is never replaced by satellite-based positioning in absolute point positioning sense. The invention of electro-optical devices at the beginning of the 21st century was really a rebirth in geodetic astronomy. Today, the digital cameras with relatively high geometric and radiometric accuracy has opened a new insight in satellite attitude determination and the study of the Earth's surface geometry and physics of its interior, i.e., computation of astronomical coordinates and the vertical deflection components. This method or the so-called astrogeodetic vision-based method help us to determine astronomical coordinates with an accuracy better than 0.1 arc second. The theoretical background, an innovative transformation approach and the preliminary numerical results are addressed in this paper.
Full Text Available The acquisition time of astronomical polarimeters has in the past been restricted to by the use of polarimeters utilizing modulated or rotating components . If the polarisation state being measured is changing in the order of nanoseconds, how does one measure this? The Galway Astronomical Stokes Polarimeter (GASP is an instantaneous full Stokes Division Of Amplitude Polarimeter (DOAP that has been developed for astronomical imaging polarimetry. It also uses just one camera thus restricting the acquisition time to photon statistics. Following the work of Compain and Drévillon , the main component - the Retarding Beam-Splitter, was redesigned and enhanced for imaging use. We present how the polarization and imaging optics were developed to create a broadband imaging instantaneous polarimeter.

Maya astronomical tables are recognized in bark-paper books from the Late Postclassic period (1300 to 1521 C.E.), but Classic period (200 to 900 C.E.) precursors have not been found. In 2011, a small painted room was excavated at the extensive ancient Maya ruins of Xultun, Guatemala, dating to the early 9th century C.E. The walls and ceiling of the room are painted with several human figures. Two walls also display a large number of delicate black, red, and incised hieroglyphs. Many of these hieroglyphs are calendrical in nature and relate astronomical computations, including at least two tables concerning the movement of the Moon, and perhaps Mars and Venus. These apparently represent early astronomical tables and may shed light on the later books.

BACKGROUND. About one third of all pregnancies are unplanned and 20% of all pregnancies end in abortion. More than 170,000 legal abortions are performed in the United Kingdom annually. Nearly all general practitioners provide contraceptive advice; the most commonly used form of reversible contraception is the oral contraceptive pill. AIM. The aim of this study was to determine factors associated with women's knowledge of taking the contraceptive pill correctly and of emergency contraception, and to investigate if their knowledge could be improved in general practice by providing women with Family Planning Association information leaflets. METHOD. An uncontrolled intervention study was performed in one rural and one urban English general practice, using a self-completion questionnaire that was initially administered to women attending their general practitioner for oral contraception over six months from 1 October 1992. The questionnaire asked for: sociodemographic information; knowledge of how late women can be taking an oral contraceptive pill and still be protected against unplanned pregnancy; for how many days after being late with a pill they need to use other precautions; sources and methods of emergency contraception; and for how long the methods are effective after the primary contraceptive failure. After completing the questionnaire women were given two leaflets: one about how to take their prescribed contraceptive pill correctly and one about emergency contraception. Three to 12 months later the same questionnaire was administered in the same manner. RESULTS. Of 449 women completing the first questionnaire, 233 (52%) completed the second questionnaire. Initially 71% of 406 women taking an oestrogen/progestogen combined pill knew about the '12-hour rule' and 17% knew about the 'seven-day rule'; giving women information about the pill they were taking increased the extent of knowledge about these rules among 212 respondents to 82% (P emergency contraception

Full Text Available Abstract Background A significant minority of patients do not receive all the evidence-based care recommended for their conditions. Health care quality may be improved by reducing this observed variation. Composite measures offer a different patient-centred perspective on quality and are utilized in acute hospitals via the ‘care bundle’ concept as indicators of the reliability of specific (evidence-based care delivery tasks and improved outcomes. A care bundle consists of a number of time-specific interventions that should be delivered to every patient every time. We aimed to apply the care bundle concept to selected QOF data to measure the quality of evidence-based care provision. Methods Care bundles and components were selected from QOF indicators according to defined criteria. Five clinical conditions were suitable for care bundles: Secondary Prevention of Coronary Heart Disease (CHD, Stroke & Transient Ischaemic Attack (TIA, Chronic Kidney Disease (CKD, Chronic Obstructive Pulmonary Disease (COPD and Diabetes Mellitus (DM. Each bundle has 3-8 components. A retrospective audit was undertaken in a convenience sample of nine general medical practices in the West of Scotland. Collected data included delivery (or not of individual bundle components to all patients included on specific disease registers. Practice level and overall compliance with bundles and components were calculated in SPSS and expressed as a percentage. Results Nine practices (64.3% with a combined patient population of 56,948 were able to provide data in the format requested. Overall compliance with developed QOF-based care bundles (composite measures was as follows: CHD 64.0%, range 35.0-71.9%; Stroke/TIA 74.1%, range 51.6-82.8%; CKD 69.0%, range 64.0-81.4%; and COPD 82.0%, range 47.9-95.8%; and DM 58.4%, range 50.3-65.2%. Conclusions In this small study compliance with individual QOF-based care bundle components was high, but overall (‘all or nothing’ compliance was

Moses Farissol Botarel (Avignon, late fifteenth century) was an astronomer who wrote in Hebrew and continued various traditions that depended on astronomy in al-Andalus which, in turn, derived in large part from the zij of al-Battānī (Raqqa, d. 929). His astronomical tables are unusual in that they combine elements from the Parisian Alfonsine Tables with elements from the tables of Levi ben Gerson (Orange, France, d. 1344), Immanuel ben Jacob Bonfils (Tarascon, France, fl. 1350), and Jacob be...

We report the latest development of a pilot project in establishing the astronomical network for teachers in Thailand. The project has been recently granted by the Institute for the Promotion of Teaching Science and Technology Thailand and operated by Sirindhorn Observatory Chiangmai University. The objectives of the project are (1) to establish a16-inch semi-robotic telescope which can be accessed from schools nationwide; and (2) to establish an educational website in Thai language which contains electronic textbook of astronomy online encyclopedia of astronomy observing projects astronomical database and links to other educational websites worldwide. The network will play important role in the development of teaching and learning astronomy in Thailand.
"We are beginning to understand that because of these observations we are going to have to change the way we look at the Universe," said ESA's Dr Duccio Macchetto, Associate Director for Science Programs at the Space Telescope Science Institute (STScI), Baltimore, Maryland, USA. The European Space Agency plays a major role in the Hubble Space Telescope programme. The Agency provided one of the telescope's four major instruments, called the Faint Object Camera, and two sets of electricity-generating solar arrays. In addition, 15 ESA scientific and technical staff work at the STScI. In return for this contribution, European astronomers are entitled to 15 percent of the telescope's observing time, although currently they account for 20 percent of all observations. "This is a testimony to the quality of the European science community", said Dr Roger Bonnet, Director of Science at ESA. "We are only guaranteed 15 percent of the telescope's use, but consistently receive much more than that." Astronomers from universities, observatories and research institutes across Europe lead more than 60 investigations planned for the telescope's fifth observing cycle, which begins this summer. Many more Europeans contribute to teams led by other astronomers. Looking back to the very start of time European astronomer Dr Peter Jakobsen used ESA's Faint Object Camera to confirm that helium was present in the early Universe. Astronomers had long predicted that 90 percent of the newly born Universe consisted of hydrogen, with helium making up the remainder. Before the refurbished Hubble came along, it was easy to detect the hydrogen, but the primordial helium remained elusive. The ultraviolet capabilities of the telescope, combined with the improvement in spatial resolution following the repair, made it possible for Dr Jakobsen to obtain an image of a quasar close to the edge of the known Universe. A spectral analysis of this picture revealed the quasar's light, which took 13 billion years

Haiti has the highest number of people living with HIV infection in the Caribbean/Latin America region. Medical male circumcision (MMC) has been recommended to help prevent the spread of HIV. We sought to assess knowledge, attitudes, practices and beliefs about MMC among a sample of health care providers in Haiti. A convenience sample of 153 health care providers at the GHESKIO Centers in Haiti responded to an exploratory survey that collected information on several topics relevant to health providers about MMC. Descriptive statistics were calculated for the responses and multivariable logistic regression was conducted to determine opinions of health care providers about the best age to perform MMC on males. Bayesian network analysis and sensitivity analysis were done to identify the minimum level of change required to increase the acceptability of performing MMC at age less than 1 year. The sample consisted of medical doctors (31.0%), nurses (49.0%), and other health care professionals (20.0%). Approximately 76% showed willingness to offer MMC services if they received training. Seventy-six percent believed that their male patients would accept circumcision, and 59% believed infancy was the best age for MMC. More than 90% of participants said that MMC would reduce STIs. Physicians and nurses who were willing to offer MMC if provided with adequate training were 2.5 (1.15-5.71) times as likely to choose the best age to perform MMC as less than one year. Finally, if the joint probability of choosing "the best age to perform MMC" as one year or older and having the mistaken belief that "MMC prevents HIV entirely" is reduced by 63% then the probability of finding that performing MMC at less than one year acceptable to health care providers is increased by 35%. Participants demonstrated high levels of knowledge and positive attitudes towards MMC. Although this study suggests that circumcision is acceptable among certain health providers in Haiti, studies with larger and

The present work presents the main results of a research carried out within the Astronomy Education field with Elementary School teachers from two regions of Rio Grande do Sul. The study aimed to show the regional panorama of teaching Astronomy compared to the national panorama already discussed in several studies in the area. It was divided into three main issues: identifying the main topics of Astronomy developed in class, verifying which were the methodological strategies used, and which were the difficulties teachers faced when developing their practice. Regarding the contents, it was found a wide range of covered topics although Earth motion and astronomical phenomena were cited by most participants. Concerning the strategies used in class, two-dimensional resources such as movies, texts, maps and web searching were mainly used. The most relevant difficulties were the lack of specific education related to Astronomy contents and abstraction level, which complicated the understanding for both students and teachers. In general, the indicators met the results already found in other studies that investigated Astronomy teaching practice, in which the teacher's original education deficiency - or even the lack of it - hampers the proper development of Astronomy contents in class. En este trabajo se presentan los principales resultados de una investigación hecha en el campo de la Educación en Astronomía, con profesores de la Enseñanza Fundamental de dos regiones de Rio Grande do Sul. El presente estudio tuvo como objetivo caracterizar el panorama regional de la enseñanza de Astronomía, estableciendo una comparación con el panorama nacional ya presentado en trabajos de referencia en el área. Ese estudio abordó tres cuestiones: identificar los principales temas de astronomía trabajados, las estrategias metodológicas y cuáles fueron las dificultades sufridas por los profesores al presentar su práctica.

Spirituality is receiving unprecedented attention in the nursing literature. Both the volume and scope of literature on the topic is expanding, and it is clear that this topic is of interest to nurses. There is consensus that the spiritual required by clients receiving health ought to be an integrated effort across the health care team. Although undergraduate nurses receive some education on the topic, this is ad hoc and inconsistent across universities. Textbooks are clearly a key resource in this area however the extent to which they form a comprehensive guide for nursing students and nurses is unclear. This study provides a hitherto unperformed analysis of core nursing textbooks to ascertain spirituality related content. 543 books were examined and this provides a range of useful information about inclusions and omissions in this field. Findings revealed that spirituality is not strongly portrayed as a component of holistic care and specific direction for the provision of spiritual care is lacking. Fundamental textbooks used by nurses and nursing students ought to inform and guide integrated spiritual care and reflect a more holistic approach to nursing care. The religious and/or spiritual needs of an increasingly diverse community need to be taken seriously within scholarly texts so that this commitment to individual clients' needs can be mirrored in practice.

The direction of health service policy in England is for more diversification in the design, commissioning and provision of health care services. The case study which is the subject of this paper was selected specifically because of the partnering with a private sector organisation to manage whole system redesign of primary care and to support the commissioning of services for people with long term conditions at risk of unplanned hospital admissions and associated service provision activities. The case study forms part of a larger Department of Health funded project on the practice of commissioning which aims to find the best means of achieving a balance between monitoring and control on the one hand, and flexibility and innovation on the other, and to find out what modes of commissioning are most effective in different circumstances and for different services. A single case study method was adopted to explore multiple perspectives of the complexities and uniqueness of a public-private partnership referred to as the "Livewell project". 10 single depth interviews were carried out with key informants across the GP practices, the PCT and the private provider involved in the initiative. The main themes arising from single depth interviews with the case study participants include a particular understanding about the concept of commissioning in the context of primary care, ambitions for primary care redesign, the importance of key roles and strong relationships, issues around the adoption and spread of innovation, and the impact of the current changes to commissioning arrangements. The findings identified a close and high trust relationship between GPs (the commissioners) and the private commissioning support and provider firm. The antecedents to the contract for the project being signed indicated the importance of leveraging external contacts and influence (resource dependency theory). The study has surfaced issues around innovation adoption in the healthcare context

During the last year the US SIMBAD Gateway Project continued to provide services like user registration to the US users of the SIMBAD database in France. Currently there are over 4300 US users registered. We also provided user support by answering questions from users and handling requests for lost passwords when still necessary. Even though almost all users now access SIMBAD without a password, based on hostnames/IP addresses, there are still some users that need individual passwords. We continued to maintain the mirror copy of the SIMBAD database on a server at SAO. This allows much faster access for the US users. During the past year we moved this mirror to a faster server to improve access for the US users. We again supported a demonstration of the SIMBAD database at the meeting of the American Astronomical Society in January. We provided support for the demonstration activities at the SIMBAD booth. We paid part of the fee for the SIMBAD demonstration. We continued to improve the cross-linking between the SIMBAD project and the Astrophysics Data System. This cross-linking between these systems is very much appreciated by the users of both the SIMBAD database and the ADS Abstract Service. The mirror of the SIMBAD database at SAO makes this connection faster for the US astronomers. We exchange information between the ADS and SIMBAD on a daily basis. The close cooperation between the CDS in Strasbourg and SAO, facilitated by this project, is an important part of the astronomy-wide digital library initiative. It has proven to be a model in how different data centers can collaborate and enhance the value of their products by linking with other data centers. We continue this collaboration in order to provide better services to both the US and European astronomical community. This collaboration is even more important in light of the developments for the Virtual Observatory projects in the different countries.

In this paper the main findings are presented of a recent study made by a team of sociologists from the University of Granada on the professional astronomers currently working in Spain. Despite the peculiarities of this group - its youth, twentyfold increase in size over the last 20 years, and extremely high rate of specialization abroad - in comparison with other Spanish professionals, this is the first time that the sociological characteristics of the group have been studied discretely. The most significant results of the study are presented in the following sections. Section 1 gives a brief historical background of the development of Astronomy in Spain. Section 2 analyzes the socio-demographic profile of Spanish Astronomy professionals (sex, age, marital status, etc.). Sections 3-5 are devoted to the college education and study programs followed by Spanish astronomers, focusing on the features and evaluations of the training received, and pre- and postdoctoral study trips made to research centers abroad. The results for the latter clearly show the importance that Spanish astronomers place on having experience abroad. Special attention is paid to scientific papers published as a result of joint research projects carried out with colleagues from centers abroad as a result of these study trips. Section 6 describes the situation of Astronomy professionals within the Spanish job market, the different positions available and the time taken to find a job after graduation. Section 7 examines Astronomy as a discipline in Spain, including the astronomers' own opinions of the social status of the discipline within Spanish society. Particular attention is paid to how Spanish astronomers view the status of Astronomy in Spain in comparison with that of other European countries.

level of financing carried out by persons with appropriate competence and qualifications. The example of Portugal discloses the status of self-organization institutions as public benefit organizations, which provides them of advantages, particularly in competition with private sector organizations. However, in the light of practical implementation of the principle of subsidiarity and other elements of decentralization is appropriate to introduce European experience in the domestic soil in the context of attracting self-organization institutions in the scope of public services delivery. The results of the study formulated the main components of a mechanism to ensure effectiveness of the self-organizations institutions in the provision of public services: subsidies of statutory activities; delegation of services; regulatory support; recognition of the status of self-organization institutions as public benefit organizations; limitation of agreements terms.

This study aimed to identify barriers and facilitating factors to people with COPD performing the following actions: (a) reading a manual that contained summaries of evidence on treatments used in chronic obstructive pulmonary disease (COPD) and (b) at a medical consultation, asking questions that were provided in the manual and were designed to prompt doctors to review current treatments in the light of evidence. The manual was developed using current best practice and was designed to facilitate reading and discussion with doctors. In-depth interviews were held with patients who had received the manual. Of 125 intervention participants from a controlled clinical trial of the manual, 16 were interviewed in their homes in and around Adelaide, South Australia. Plain language writing and a simple layout facilitated reading of the manual by participants. Where the content matched the interests of participants this also facilitated reading. On the other hand, some participants showed limited interest in the evidence summaries. Participant comments indicated that they did not see it as possible or acceptable for patients to master research evidence or initiate discussions of evidence with doctors. These appeared to be the main barriers to effectiveness of the manual. If evidence summaries for patients are to be used in disease management, they should be understandable and relevant to patients and provide a basis for discussion between patients and doctors. Work is now needed so that we can both present evidence summaries in a way that is relevant to patients and reduce the barriers to patient-initiated discussions of evidence.
This policy statement serves to combine and update 2 previously independent but overlapping statements from the American Academy of Pediatrics (AAP) on culturally effective health care (CEHC) and workforce diversity. The AAP has long recognized that with the ever-increasing diversity of the pediatric population in the United States, the health of all children depends on the ability of all pediatricians to practice culturally effective care. CEHC can be defined as the delivery of care within the context of appropriate physician knowledge, understanding, and appreciation of all cultural distinctions, leading to optimal health outcomes. The AAP believes that CEHC is a critical social value and that the knowledge and skills necessary for providing CEHC can be taught and acquired through focused curricula across the spectrum of lifelong learning. This statement also addresses workforce diversity, health disparities, and affirmative action. The discussion of diversity is broadened to include not only race, ethnicity, and language but also cultural attributes such as gender, religious beliefs, sexual orientation, and disability, which may affect the quality of health care. The AAP believes that efforts must be supported through health policy and advocacy initiatives to promote the delivery of CEHC and to overcome educational, organizational, and other barriers to improving workforce diversity.

The Institute for Student Astronomical Research over the past two years has provided dozens of high school and college students the opportunity to conduct original research in astronomy and to publish their work in peer-reviewed journals. Students are engaged in the entire scientific process from coming up with a research question to collecting and analyzing the data and writing up their results for publication. During the process students work with amateur and/or professional astronomers to learn how to conduct their research and communicate their findings effectively. Working within a community of practice has been shown to improve student learning and the Institute for Student Astronomical Research provides a framework in which to bring students and astronomers together while allowing for the work to be done in a student-centered fashion.
The STScI Library assists the Science Policies Division in evaluating and choosing scientific keywords and categories for proposals for the Hubble Space Telescope mission and the upcoming James Webb Space Telescope mission. In addition we are often faced with the question “what is the shape of the astronomical literature?” However, subject classification in astronomy in recent times has not been cultivated. This talk will address the available tools and challenges of classifying cutting-edge as well as historical astronomical documents. In at the process, we will give an overview of current and upcoming practices of subject classification in astronomy.
In 1964-1974, the German artist Max Ernst created, with the help of two friends, a series of works (books, movie, and paintings) related to the astronomer Wilhelm Tempel. Mixing actual texts by Tempel and artistic features, this series pays homage to the astronomer by recalling his life and discoveries. Moreover, the core of the project, the book Maximiliana or the Illegal Practice of Astronomy, actually depicts the way science works, making this work of art a most original tribute to a scientist.
Astronomers at Sweet Briar College and the Naval Research Laboratory (NRL) have detected a powerful new bursting radio source whose unique properties suggest the discovery of a new class of astronomical objects. The researchers have monitored the center of the Milky Way Galaxy for several years and reveal their findings in the March 3, 2005 edition of the journal, “Nature”. This radio image of the central region of the Milky Way Galaxy holds a new radio source, GCRT J1745-3009. The arrow points to an expanding ring of debris expelled by a supernova. CREDIT: N.E. Kassim et al., Naval Research Laboratory, NRAO/AUI/NSF Principal investigator, Dr. Scott Hyman, professor of physics at Sweet Briar College, said the discovery came after analyzing some additional observations from 2002 provided by researchers at Northwestern University. “"We hit the jackpot!” Hyman said referring to the observations. “An image of the Galactic center, made by collecting radio waves of about 1-meter in wavelength, revealed multiple bursts from the source during a seven-hour period from Sept. 30 to Oct. 1, 2002 — five bursts in fact, and repeating at remarkably constant intervals.” Hyman, four Sweet Briar students, and his NRL collaborators, Drs. Namir Kassim and Joseph Lazio, happened upon transient emission from two radio sources while studying the Galactic center in 1998. This prompted the team to propose an ongoing monitoring program using the National Science Foundation’s Very Large Array (VLA) radio telescope in New Mexico. The National Radio Astronomy Observatory, which operates the VLA, approved the program. The data collected, laid the groundwork for the detection of the new radio source. “Amazingly, even though the sky is known to be full of transient objects emitting at X- and gamma-ray wavelengths,” NRL astronomer Dr. Joseph Lazio pointed out, “very little has been done to look for radio bursts, which are often easier for astronomical objects to produce

The U.S. Virtual Astronomical Observatory (VAO) is a product-driven organization that provides new scientific research capabilities to the astronomical community. Software development for the VAO follows a lightweight framework that guides development of science applications and infrastructure. Challenges to be overcome include distributed development teams, part-time efforts, and highly constrained schedules. We describe the process we followed to conquer these challenges while developing Iris, the VAO application for analysis of 1-D astronomical spectral energy distributions (SEDs). Iris was successfully built and released in less than a year with a team distributed across four institutions. The project followed existing International Virtual Observatory Alliance inter-operability standards for spectral data and contributed a SED library as a by-product of the project. We emphasize lessons learned that will be folded into future development efforts. In our experience, a well-defined process that provides guidelines to ensure the project is cohesive and stays on track is key to success. Internal product deliveries with a planned test and feedback loop are critical. Release candidates are measured against use cases established early in the process, and provide the opportunity to assess priorities and make course corrections during development. Also key is the participation of a stakeholder such as a lead scientist who manages the technical questions, advises on priorities, and is actively involved as a lead tester. Finally, frequent scheduled communications (for example a bi-weekly tele-conference) assure issues are resolved quickly and the team is working toward a common vision.

To identify attitudes and practices of endocrinologists (ENDOs), family practitioners (FPs), internists (IMs), primary care nurse practitioners (NPs), physician assistants (PAs), certified diabetes educators (CDEs), retail pharmacists (R-PHs), and hospital pharmacists (H-PHs) with respect to type 2 diabetes mellitus (T2DM) management; to compare current study data with results from a similar 2011 study. A nominal group technique focus group identified barriers to optimal management of patients with T2DM. Five case-vignette surveys were created, 1 for each group of health care professionals (HCPs): ENDOs; FPs and IMs; NPs and PAs; CDEs; and R-PHs and H-PHs. Surveys were tailored to each group. Versions were as similar as possible to each other and to the 2011 surveys to facilitate comparisons. Questions assessed guideline familiarity; knowledge of insulin formulations, glucagon-like peptide-1 (GLP-1) receptor agonists, dipeptidyl peptidase-4 (DPP-4) inhibitors; patterns of referral to ENDOs and CDEs; as well as cultural barriers and communication barriers. Surveys were distributed by e-mail/fax to a nationally representative, random sample of US HCPs during January and February 2013. Notable shifts from 2011 included NPs' increased familiarity with American Diabetes Association (ADA) guidelines; FPs, IMs, NPs, and PAs continued comfort with prescribing long-acting basal insulin but less with basal-bolus, Neutral Protamine Hagedorn insulin alone, or human premixed insulin; increased pharmacists' comfort in discussing long-acting basal insulin; increased likelihood that FPs will refer patients with recurrent hypoglycemia unable to achieve target glycated hemoglobin level to an ENDO; and continued incorporation of insulin and incretins into treatment regimens. The trends suggest gaps in perception, knowledge, and management practices to be addressed by education. Most HCPs lack confidence in using insulin regimens more complex than long-acting insulin alone. All
Full Text Available The recent extensive digitisation of astronomical photographic plate archives, the development of new dedicated software and the use of powerful computers have for the first time enabled effective data mining in extensive plate databases, with wide applications in various fields of recent astrophysics. As an example, analyses of supermassive binary black holes (binary blazars require very long time intervals (50 years and more, which cannot be provided by other data sources. Examples of data obtained from data mining in plate archives are presented and briefly discussed.

We survey the job situation of women in astronomy in Germany and of German women abroad and review indicators for their career development. Our sample includes women astronomers from all academic levels from doctoral students to professors, as well as female astronomers who have left the field. We find that networking and human support are among the most important factors for success. Experience shows that students should carefully choose their supervisor and collect practical knowledge abroad. We reflect the private situation of female German astronomers and find that prejudices are abundant, and are perceived as discriminating. We identify reasons why women are more likely than men to quit astronomy after they obtain their PhD degree. We give recommendations to young students on what to pay attention to in order to be on the successful path in astronomy.

The quality of modern astronomical data and the agility of current image-processing software enable the visualization of data in a way that exceeds the traditional definition of an astronomical image. Two developments in particular have led to a fundamental change in how astronomical images can be assembled. First, the availability of high-quality multiwavelength and narrowband data allow for images that do not correspond to the wavelength sensitivity of the human eye, thereby introducing ambiguity in the usage and interpretation of color. Second, many image-processing software packages now use a layering metaphor that allows for any number of astronomical data sets to be combined into a color image. With this technique, images with as many as eight data sets have been produced. Each data set is intensity-scaled and colorized independently, creating an immense parameter space that can be used to assemble the image. Since such images are intended for data visualization, scaling and color schemes must be chosen that best illustrate the science. A practical guide is presented on how to use the layering metaphor to generate publication-ready astronomical images from as many data sets as desired. A methodology is also given on how to use intensity scaling, color, and composition to create contrasts in an image that highlight the scientific detail. Examples of image creation are discussed.

SPHEREx, a mission in NASA's Medium Explorer (MIDEX) program that was selected for Phase A study in August 2017, will perform an all-sky near-infrared spectral survey between 0.75 - 5.0 microns. The survey will reach 18.3 AB mag (5 sigma) in R=41 filters, with R=135 coverage between 4.2 - 5.0 microns. The key science topics of the SPHEREx team are: (a) primordial non-Gaussianity through 3-dimensional galaxy clustering; (b) extragalactic background light fluctuations; and (c) ices and biogenic molecules in the interstellar medium and towards protoplanetary environments.The large legacy dataset of SPHEREx will enable a large number of scientific studies and find interesting targets for follow-up observations with Hubble, JWST, ALMA, among other facilities. The SPHEREx catalog will include 1.4 billion galaxies, with redshifts secured for more than 10 and 120 million with fractional accuracies in error/(1+z) better than 0.3% and 3%, respectively. The spectral coverage and resolution provided by SPHEREx are adequate to determine redshifts for most WISE-detected sources with an accuracy better than 3%. The catalog will contain close to 1.5 million quasars including 300 bright QSOs at z > 7 during the epoch of reionization, based on observational extrapolations. The catalog will be adequate to obtain redshifts for all 25,000 galaxy clusters expected to be detected in X-rays with e-Rosita. SPHEREx produces all-sky maps of the Galactic emission lines, including hydrocarbon emission around 3 microns.In this poster, we will show example science studies the broader astronomical community will be able to lead using the SPHEREx database. We will also outline existing plans within the SPHEREx team to develop software tools to enable easy access to the data and to conduct catalog searches, and ways in which the community can provide input to the SPHEREx Science Team on scientific studies and data/software requirements for those studies. The team is eager to develop best software

Recent lossless still image compression formats are powerful tools for compression of all kind of common images (pictures, text, schemes, etc.). Generally, the performance of a compression algorithm depends on its ability to anticipate the image function of the processed image. In other words, a compression algorithm to be successful, it has to take perfectly the advantage of coded image properties. Astronomical data form a special class of images and they have, among general image properties, also some specific characteristics which are unique. If a new coder is able to correctly use the knowledge of these special properties it should lead to its superior performance on this specific class of images at least in terms of the compression ratio. In this work, the novel lossless astronomical image data compression method will be presented. The achievable compression ratio of this new coder will be compared to theoretical lossless compression limit and also to the recent compression standards of the astronomy and general multimedia.

El presente trabajo, es una revisión crítica de la astronomía en la cultura Mocoví, aportando a lo realizado previamente por Lehmann Nistche (Lehmann Nistche, 1924 y 1927) el resultado de nuestro trabajo de campo. Un mayor conocimiento de las cosmovisiones de las etnias de esta área es fundamental para una mejor comprensión de la dispersión de las ideas cosmológicas entre los pueblos aborígenes americanos, dada la importancia del corredor chaqueño como conexión entre las altas culturas andinas, la mesopotamia y la región pampeana (Susnik, 1972). Para ello se realiza una comparación con otras cosmovisiones del área americana. Nuestro aporte se enmarca dentro de las actuales líneas de trabajo mundialmente en desarrollo en Astronomía en la Cultura.

Following the line set by his earlier book 'The crime of Claudius Ptolemy' the author discusses here the numerous astronomical tables in Ptolemy's work that have been calculated with the aid of trigonometric tables, as well as a few that are nonlinear but that do not involve trigonometry. The purpose in this study is to determine, if possible, whether Ptolemy calculated these tables or whether he copied them from now-lost original works. The conclusion isthat Ptolemy made few if any original contributions to astronomy, either observational or computational.Contents: 1. Introduction; thetable of chords. 2. The tables of the latitude and of gnomon shadows.3. Tables of the Sun. 4. Astronomical geography. 5. The tables of theMoon. 6. Eclipse tables. 7. Tables of the planets. 8. The empirical basis for Hipparchus's mean motions of the Moon. 9. Summary and conclusions.

In this document, an approach to the development of WWW-accessible astronomical archives and databases is described, which can easily be extended also to other disciplines. The architecture is based on a set of servers running at the archive site, each performing a specialized task: accessing an SQL-based DBMS, retrieving and downlinking 1-D or 2-D data (measurements), displaying quicklook data, or plotting the results of a query to the database. All of the information on the user interface is dynamically stored in the database, allowing the pages to be prepared on-the-fly; no additional software needs to be run on the user’s computer. A WWW-accessible test astronomical archive, containing both 2-D (images) and 1-D (spectra) data, and having NCSA/Mosaic as an interface is described as an example of successful application of the above concepts.
Lehn, Waldemar H
In a short interval toward the end of 1694, Isaac Newton developed two mathematical models for the theory of the astronomical refraction and calculated two refraction tables, but did not publish his theory. Much effort has been expended, starting with Biot in 1836, in the attempt to identify the methods and equations that Newton used. In contrast to previous work, a closed form solution is identified for the refraction integral that reproduces the table for his first model (in which density decays linearly with elevation). The parameters of his second model, which includes the exponential variation of pressure in an isothermal atmosphere, have also been identified by reproducing his results. The implication is clear that in each case Newton had derived exactly the correct equations for the astronomical refraction; furthermore, he was the first to do so.

While lesbian, gay, bisexual, transgender, intersex, or questioning (LGBTIQ) astronomers face many of the same workplace challenges as women and racial/ethnic minorities, from implicit bias to overt discrimination, other challenges are unique to this group. An obvious example is the absence at many institutions of health insurance and other benefits for the same-sex domestic partners of their employees. More subtle is the psychological toll paid by LGBTIQ astronomers who remain "in the closet," self-censoring every statement about their personal lives. Paradoxically, the culture of the physical sciences, in which sexuality, gender identity, and gender expression are considered irrelevant, can discourage their discussion, further isolating LGBTIQ researchers. Addressing these challenges is not just a matter of fairness; it is an essential tool in the recruitment and retention of the brightest researchers and in assuring their productivity. We will discuss these issues and what individuals and departments can to make their institutions more welcoming to their LGBTIQ colleagues.

Astrophotonics lies at the interface of astronomy and photonics. This burgeoning field has emerged over the past decade in response to the increasing demands of astronomical instrumentation. Early successes include: (i) planar waveguides to combine signals from widely spaced telescopes in stellar interferometry; (ii) frequency combs for ultra-high precision spectroscopy to detect planets around nearby stars; (iii) ultra-broadband fibre Bragg gratings to suppress unwanted background; (iv) photonic lanterns that allow single-mode behaviour within a multimode fibre; (v) planar waveguides to miniaturize astronomical spectrographs; (vi) large mode area fibres to generate artificial stars in the upper atmosphere for adaptive optics correction; (vii) liquid crystal polymers in optical vortex coronographs and adaptive optics systems. Astrophotonics, a field that has already created new photonic capabilities, is now extending its reach down to the Rayleigh scattering limit at ultraviolet wavelengths, and out to mid infrared wavelengths beyond 2500 nm.
Dr J. Landi Dessy, Director of the Astronomical Observatory, Cordoba, Argentina, invited the International Astronomical Union to hold a Symposium in Cordoba in connection with the celebration of the Centennial of the Cordoba Observatory; the date of foundation is October 24, 1871. He proposed that the Symposium should deal with Spectral Classification and Multicolour Photometry as seven years had elapsed since the Symposium No. 24 in Saltsj6baden, and much development had occurred in the field. The invitation and the proposal were accepted by the IAU, and the Symposium was held in Villa Carlos Paz, near Cordoba, between October 18 and October 24, 1971. It was attended by about 50 scientists representing Argentina, Canada, Chile, Den mark, France, Germany, Italy, Mexico, Sweden, Switzerland, U.K., U.S.A., Vatican City State and Venezuela. The Symposium was divided into four sessions: 1. Classification of slit spectra, 2. Classification of objective-prism spectra, 3. Photometric classification, 4. Catalogues ...

Before CCD detectors were widely employed in observational astronomy, the main method of detection was the use of glass astrophotographic plates. Astronomical plates have been used to record information on the position and activity of celestial bodies for more than 100 years. There are about 30 000 astronomical plates in China, and the digitization of astronomical plates is of great significance for permanent preservation and to make full use of these valuable observation data. A digitizer with high precision and high measuring speed is a key piece of equipment for carrying out the task of digitizing these astronomical plates. A digitizer for glass astrophotographic plates was developed jointly by Shanghai Astronomical Observatory and Nishimura Co., Ltd of Japan. The digitizer’s hardware was manufactured by Nishimura Co., Ltd, and the performance test, error corrections as well as image processing of the digitizer were carried out by Shanghai Astronomical Observatory. The main structure and working mode of the digitizer are introduced in this paper. A performance test shows that brightness uniformity of illumination within the measuring area is better than 0.15%, the repeatability of digitized positions is better than 0.2 µm and the repeatability of digitized brightness is better than 0.01 instrumental magnitude. The systematic factors affecting digitized positions, such as lens distortion, the actual optical resolution, non-linearity of guide rails, non-uniformity of linear motors in the mobile platform, deviation of the image mosaic, and non-orthogonality between the direction of scanning and camera linear array, are calibrated and evaluated. Based on an astronomical plate with a size of 300mm × 300mm, which was digitized at different angles, the conversion residuals of positions of common stars on different images were investigated. The results show that the standard deviations of the residuals are better than 0.9 µm and the residual distribution is almost
Celestial Delights is the essential 'TV Guide' for the sky. Through extensive graphics integrated with an eight-year-long calendar of sky events, it provides a look at "don't miss" sky events, mostly for naked-eye and binocular observing. It is organized by ease of observation – lunar phases and the brighter planets come first, with solar eclipses, the aurora, and comets coming later. This third edition also includes a hefty dose of sky lore, astronomical history, and clear overviews of current science. It provides a handy reference to upcoming naked-eye events, with information broken out in clear and simple diagrams and tables that are cross-referenced against a detailed almanac for each year covered. This book puts a variety of information all in one place, presents it in a friendly way that does not require prior in-depth astronomical knowledge, and provides the context and historical background for understanding events that astronomy software or web sites lack.

A hard difficulty in Astrobiology is the precise definition of what life is. All living beings have a cellular structure, so it is not possible to have a broader concept of life hence the search for extraterrestrial life is restricted to extraterrestrial cells. Earth is an astronomical rarity because it is difficult for a planet to present liquid water on the surface. Two antagonistic bioethical principles arise: planetary protection and terraforming. Planetary protection is based on the fear...

Full Text Available The linkage between astronomical cycles and the periodicity of mass extinctions is reviewed and discussed. In particular, the apparent 26 million year cycle of global extinctions may be related to the motion of the solar system around the galaxy, especially perpendicular to the galactic plane. The potential relevance of Milankovitch cycles is also explored in the light of current evidence for the possible causes of extinction events over a geological timescale.
This is the extensively revised edition of the classic book that presented the author's discovery of an astronomical code in the organization of the Rgveda. This code has changed our understanding of the Vedic system of knowledge, rise of earliest astronomy, history of science, and the chronology of ancient India. The work was first reported in a series of journal articles; this book brings together these discoveries between the same two covers for the first time.
Noticias del Cosmos is a collection of web pages within the Astronomical Observatory of the University of Valencia's website where we publish short daily summaries of astronomical press releases. Most, if not all of, the releases are originally written in English, and often Spanish readers may find them difficult to understand because not many people are familiar with the scientific language employed in these releases. Noticias del Cosmos has two principal aims. First, we want to communicate the latest astronomical news on a daily basis to a wide Spanish-speaking public who would otherwise not be able to read them because of the language barrier. Second, daily news can be used as a tool to introduce the astronomical topics of the school curriculum in a more immediate and relevant way. Most of the students at school have not yet reached a good enough level in their knowledge of English to fully understand a press release, and Noticias del Cosmos offers them and their teachers this news in their mother tongue. During the regular programme of school visits at the Observatory we use the news as a means of showing that there is still a lot to be discovered. So far the visits to the website have been growing steadily. Between June 2003 and June 2007 we had more than 30,000 visits (excluding 2006). More than 50% of the visits come from Spain, followed by visitors from South and Central America. The feedback we have received from teachers so far has been very positive, showing the usefulness of news items in the classroom when teaching astronomy.

Prehistoric sanctuaries of Daunia date back several thousand years. During the Neolithic and Bronze Ages the farmers in that region dug hypogea and holes whose characteristics suggest a ritual use. In the present article we summarize the results of the astronomical analysis of the orientation of the rows of holes in three different sites, and we point out the possible use of the setting of the stars of Centaurus. An interesting archaeological confirmation of an archaeoastronomical prediction is also reported.

"Data integration" generally refers to the process of combining data from different source data bases into a unified view. Much work has been devoted in this area by the International Virtual Observatory Alliance (IVOA), allowing users to discover and access databases through standard protocols. However, different archives present their data through their own schemas and users must still select, filter, and combine data for each archive individually. An important reason for this is that the creation of common data models that satisfy all sub-disciplines is fraught with difficulties. Furthermore it requires a substantial amount of work for data providers to present their data according to some standard representation. We will argue that existing standards allow us to build a data integration framework that works around these problems. The particular framework requires the implementation of the IVOA Table Access Protocol (TAP) only. It uses the newly developed VO data modelling language (VO-DML) specification, which allows one to define extensible object-oriented data models using a subset of UML concepts through a simple XML serialization language. A rich mapping language allows one to describe how instances of VO-DML data models are represented by the TAP service, bridging the possible mismatch between a local archive's schema and some agreed-upon representation of the astronomical domain. In this so called local-as-view approach to data integration, “mediators" use the mapping prescriptions to translate queries phrased in terms of the common schema to the underlying TAP service. This mapping language has a graphical representation, which we expose through a web based graphical “drag-and-drop-and-connect" interface. This service allows any user to map the holdings of any TAP service to the data model(s) of choice. The mappings are defined and stored outside of the data sources themselves, which allows the interface to be used in a kind of crowd-sourcing effort
Full Text Available The Galway Astronomical Stokes Polarimeter (GASP is an ultra-high-speed, full Stokes, astronomical imaging polarimeter based upon a Division of Amplitude Polarimeter. It has been developed to resolve extremely rapid stochastic (~ms variations in objects such as optical pulsars, magnetars and magnetic cataclysmic variables. The polarimeter has no moving parts or modulated components so the complete Stokes vector can be measured from just one exposure - making it unique to astronomy. The time required for the determination of the full Stokes vector is limited only by detector efficiency and photon fluxes. The polarimeter utilizes a modified Fresnel rhomb that acts as a highly achromatic quarter wave plate and a beamsplitter (referred to as an RBS. We present a description of how the DOAP works, some of the optical design for the polarimeter. Calibration is an important and difficult issue with all polarimeters, but particularly in astronomical polarimeters. We give a description of calibration techniques appropriate to this type of polarimeter.
Full Text Available Astronomical Virtual Observatories (VOs are emerging research environment for astronomy, and 16 countries and a region have funded to develop their VOs based on international standard protocols for interoperability. The 16 funded VO projects have established the International Virtual Observatory Alliance (http://www.ivoa.net/ to develop the standard interoperable interfaces such as registry (meta data, data access, query languages, output format (VOTable, data model, application interface, and so on. The IVOA members have constructed each VO environment through the IVOA interfaces. National Astronomical Observatory of Japan (NAOJ started its VO project (Japanese Virtual Observatory - JVO in 2002, and developed its VO system. We have succeeded to interoperate the latest JVO system with other VOs in the USA and Europe since December 2004. Observed data by the Subaru telescope, satellite data taken by the JAXA/ISAS, etc. are connected to the JVO system. Successful interoperation of the JVO system with other VOs means that astronomers in the world will be able to utilize top-level data obtained by these telescopes from anywhere in the world at anytime. System design of the JVO system, experiences during our development including problems of current standard protocols defined in the IVOA, and proposals to resolve these problems in the near future are described.
Do you write code for your research? Use astronomical software? Do you wish there were a better way of citing, sharing, archiving, or discovering software for astronomy research? You're not alone! In April 2015, AAS's publishing team joined other leaders in the astronomical software community in a meeting funded by the Sloan Foundation, with the purpose of discussing these issues and potential solutions. In attendance were representatives from academic astronomy, publishing, libraries, for-profit software sharing platforms, telescope facilities, and grantmaking institutions. The goal of the group was to establish “protocols, policies, and platforms for astronomical software citation, sharing, and archiving,” in the hopes of encouraging a set of normalized standards across the field. The AAS is now collaborating with leaders at GitHub to write grant proposals for a project to develop strategies for software discoverability and citation, in astronomy and beyond. If this topic interests you, you can find more details in this document released by the group after the meeting: http://astronomy-software-index.github.io/2015-workshop/ The group hopes to move this project forward with input and support from the broader community.

GalileoMobile is an itinerant science education initiative run on a voluntary basis by an international team of astronomers, educators, and science communicators. Our team's main goal is to make astronomy accessible to schools and communities around the globe that have little or no access to outreach actions. We do this by performing teacher workshops, activities with students, and donating educational material. Since the creation of GalileoMobile in 2008, we have travelled to Chile, Bolivia, Peru, India, and Uganda, and worked with 56 schools in total. Our activities are centred on the GalileoMobile Handbook of Activities that comprises around 20 astronomical activities which we adapted from many different sources, and translated into 4 languages. The experience we gained in Chile, Bolivia, Peru, India, and Uganda taught us that (1) bringing experts from other countries was very stimulating for children as they are naturally curious about other cultures and encourages a collaboration beyond borders; (2) high-school students who were already interested in science were always very eager to interact with real astronomers doing research to ask for career advice; (3) inquiry-based methods are important to make the learning process more effective and we have therefore, re-adapted the activities in our Handbook according to these; (4) local teachers and university students involved in our activities have the potential to carry out follow-up activities, and examples are those from Uganda and India.

The quality of modern astronomical data, the power of modern computers and the agility of current image-processing software enable the creation of high-quality images in a purely digital form. The combination of these technological advancements has created a new ability to make colour astronomical images. These programs use a layering metaphor that allows for an unlimited number of astronomical datasets to be combined in any desired colour scheme, creating an immense parameter space to be explored. A philosophy is presented on how to use scaling, colour and composition to create images that simultaneously highlight scientific detail and are aesthetically appealing. This philosophy is necessary because most datasets do not correspond to the wavelength range of sensitivity of the human eye. The use of visual grammar, defined as the elements that affect the interpretation of an image, can maximize the richness and detail in an image while maintaining scientific accuracy. By properly using visual grammar, one can imply qualities that a two-dimensional image cannot show intrinsically, such as depth, motion and energy. In addition, composition can be used to engage viewers and keep them interested for a longer period of time. The use of these techniques can result in a striking image that will effectively convey the science within the image to scientists and to the public. Details of the pictorial examples used are presented in the conference web-proceedings and webcast.
The work presented in this thesis aims at: a) providing fundamental knowledge on the interactions of simple ligands with metal clusters relevant to astronomical and (bio-) catalytical processes, b) providing a benchmark that can be used to test current and future DFT methods developed to study these

Continuous renal replacement therapy (CRRT) use continues to expand globally. Despite improving technology, CRRT remains a complex intervention. Delivery of high-quality CRRT requires close collaboration of a multidisciplinary team including members of the critical care medicine, nephrology, nursing, pharmacy, and nutrition support teams. While significant gaps in medical evidence regarding CRRT persist, the growing evidence base supports evolving best practice and consensus to define high-quality CRRT. Unfortunately, there is wide variability in CRRT operating characteristics and limited uptake of these best practices. This article will briefly review the current best practice on important aspects of CRRT delivery including CRRT dose, anticoagulation, dialysis vascular access, fluid management, and drug dosing in CRRT.

The Jesuit priest Christopher Scheiner was one of the most influential astronomers of the first half of the 17th century. He was a creative and down-to-earth natural scientist who worked in the fields of astronomy, physics, optics and ophthalmology, while following his vocations as university lecturer, church builder and pastor. In scientific matters he was Galilei's opponent. Their dispute centred on the priority of discovery in regard to the sunspots. Scheiner was not the first to discover the sunspots, but he gave the most detailed account thereofin his main work "Rosa Ursina sive Sol". He was, however, ceaseless in his defense of the geocentric system. In 1891, Anton v.Braunmühl published a biography of Father Scheiner. Ever since then, new documents have come to light, justifying the publication of a new biography. Among the documents now available is Scheiner's hitherto unknown dissertation. Notes taken during his lectures in Ingolstadt provide valuable information on astronomy using the telescope, an invention of his lifetime. His exchange of letters with personalities like Archduke Leopold V of Austria-Tyrol, with scientists like Magini, Galilei, Gassendi, Kepler and confriars Rader, Guldin, Alber, Minutuli, Cysat und Kircher is a source of precious insights. Letters to Scheiner from the Father Generals of his order display evidence of his superiors' zero tolerance for the helincentric system. They also disclose Scheiner's wish to become a missionary in China, the financial difficulties he faced while trying to find a publisher for his "Rosa Ursina sive Sol" and his personal shortcomings. A Scheiner obituary from 1650 was found in Cracow in 2001. It contains information on the troublesome last years of his life and has finally allowed us to determine the year of his birth. Scheiner's personality has been praised as well as criticized by many authors - sometimes depending on their ideological backgrounds. This holds true especially regarding the argument

This book is for the aging amateur astronomy population, including newcomers to astronomy in their retirement and hobbyists who loved peering through a telescope as a child. Whether a novice or an experienced observer, the practice of astronomy differs over the years. This guide will extend the enjoyment of astronomy well into the Golden Years by addressing topics such as eye and overall health issues, recommendations on telescope equipment, and astronomy-related social activities especially suited for seniors. Many Baby-Boomers reaching retirement age are seeking new activities, and amateur astronomy is a perfect fit as a leisure time activity. Established backyard astronomers who began their love of astronomy in their youth , meanwhile, may face many physical and mental challenges in continuing their lifelong hobby as they age beyond their 55th birthdays. That perfect telescope purchased when they were thirty years old now suddenly at sixty years old feels like an immovable object in the living room. The 20...

The question of how to increase the number of women and minorities in astronomy has been approached from several directions in the United States including examination of admission policies, mentoring, and hiring practices. These point to departmental efforts to improve conditions for some of the students which has the overall benefit of improving conditions for all of the students. However, women and minority astronomers have managed to obtain doctorates even within the non-welcoming environment of certain astronomy and physics departments. I present here six strategies used by African American men and women to persevere if not thrive long enough to earn their doctorate. Embedded in this analysis is the idea of `astronomy culture' and experiencing astronomy culture as a cross-cultural experience including elements of culture shock. These survival strategies are not exclusive to this small subpopulation but have been used by majority students, too.

Full Text Available Abstract Background Many health professionals lack the skills to find and appraise published research. This lack of skills and associated knowledge needs to be addressed, and practice habits need to change, for evidence-based practice to occur. The aim of this before and after study was to evaluate the effect of a multifaceted intervention on the knowledge, skills, attitudes and behaviour of allied health professionals. Methods 114 self-selected occupational therapists were recruited. The intervention included a 2-day workshop combined with outreach support for eight months. Support involved email and telephone contact and a workplace visit. Measures were collected at baseline, post-workshop, and eight months later. The primary outcome was knowledge, measured using the Adapted Fresno Test of Evidence-Based Practice (total score 0 to 156. Secondary outcomes were attitude to evidence-based practice (% reporting improved skills and confidence; % reporting barriers, and behaviour measured using an activity diary (% engaging/not engaging in search and appraisal activities, and assignment completion. Results Post-workshop, there were significant gains in knowledge which were maintained at follow-up. The mean difference in the Adapted Fresno Test total score was 20.6 points (95% CI, 15.6 to 25.5. The change from post-workshop to follow-up was small and non-significant (mean difference 1.2 points, 95% CI, -6.0 to 8.5. Fewer participants reported lack of searching and appraisal skills as barriers to evidence-based practice over time (searching = 61%, 53%, 24%; appraisal 60%, 65%, 41%. These differences were statistically significant (p = 0.0001 and 0.010 respectively. Behaviour changed little. Pre-workshop, 6% engaged in critical appraisal increasing to 18% post-workshop and 18% at follow-up. Nearly two thirds (60% were not reading any research literature at follow-up. Twenty-three participants (20.2% completed their assignment. Conclusion Evidence

There is a reported association between high clinical volume and improved outcomes. Whether this relationship is true for outpatients with coronary artery disease (CAD), heart failure (HF), and atrial fibrillation (AF) remains unknown. Using the PINNACLE Registry (2009-2012), average monthly provider and practice volumes were calculated for CAD, HF, and AF. Adherence with 4 American Heart Association CAD, 2 HF, and 1 AF performance measure were assessed at the most recent encounter for each patient. Hierarchical logistic regression models were used to assess the relationship between provider and practice volume and performance on eligible quality measures. Data incorporated patients from 1094 providers at 71 practices (practice level analyses n=654 535; provider level analyses n=529 938). Median monthly provider volumes were 79 (interquartile range [IQR], 51-117) for CAD, 27 (16-45) for HF, and 37 (24-54) for AF. Median monthly practice volumes were 923 (IQR, 476-1455) for CAD, 311 (145-657) for HF, and 459 (185-720) for AF. Overall, 55% of patients met all CAD measures, 72% met all HF measures, and 58% met the AF measure. There was no definite relationship between practice volume and concordance for CAD, AF, or HF (P=0.56, 0.52, and 0.79, respectively). In contrast, higher provider volume was associated with increased concordance for CAD and AF performance measures (Pperformance was modest and variable. Higher provider volume was positively associated with quality, whereas practice volume was not. © 2015 American Heart Association, Inc.

The provision of end-of-life (EOL) care by geriatric health service facilities (GHSFs) in Japan is increasing. Advance care planning (ACP) is one of the most important issues to provide quality EOL care. This study aimed to clarify the practice and perceived importance of ACP and the difficulties in providing palliative care in GHSFs. A self-report questionnaire was mailed to head nurses at 3437 GHSFs nationwide. We asked participants about their practices regarding ACP, their recognition of its importance, and their difficulties in providing palliative care. We also analyzed the relationship between these factors and EOL care education. Among 844 respondents (24.5% response rate), approximately 69% to 81% of head nurses confirmed that GHSF residents and their families understood disease conditions and goals of care. There was a large discrepancy between the actual practice of ACP components and the recognition of their importance (eg, asking residents about existing advance directive [AD; 27.5% practiced it, while 79.6% considered it important]; recommending completion of an AD [18.1% vs 68.4%], and asking for designation of a health-care proxy [30.4% vs 76.8%]). The EOL care education was provided at 517 facilities (61.3%). Head nurses working at EOL care education-providing GHSFs practiced ACP significantly more frequently and had significantly fewer difficulties in providing palliative care. A large discrepancy was found between GHSF nurses' practice of ACP and their recognition of its importance. Providing EOL care education in GHSFs may increase ACP practices and enhance respect for resident's preferences concerning EOL care.
Astronomical mirrors are key elements in modern optical telescopes, their dimensions are usually large and their specifications are demanding. Only a limited number of skilled companies respectively institutions around the world are able to master the challenge to polish an individual astronomical mirror, especially in dimensions above one meter. This paper presents an overview on the corresponding market including a listing of polishers around the globe. Therefore valuable information is provided to the astronomical community: Polishers may use the information as a global competitor database, astronomers and project managers may get more transparency on potential suppliers, and suppliers of polishing equipment may learn about unknown potential customers in other parts of the world. An evaluation of the historical market demand on large monolithic astronomical mirrors is presented. It concluded that this is still a niche market with a typical mean rate of 1-2 mirrors per year. Polishing of such mirrors is an enabling technology with impact on the development of technical know-how, public relation, visibility and reputation of the supplier. Within a corresponding technical discussion different polishing technologies are described. In addition it is demonstrated that strategic aspects and political considerations are influencing the selection of the optical finisher.

This paper explores the perceived challenges facing clinical genetics practitioners in multicultural Australia. Focus groups conducted with 53 practitioners explored: 1) participants' experiences and definitions of cultural diversity; 2) their use of educational resources with clients; 3) their experiences with culturally diverse groups/individuals in practice; 4) their experiences working with interpreters; and 5) the impact culturally specific educational training and/or experiential learning had on their confidence or practice when dealing with culturally diverse clients. Participants viewed culture as extending beyond traditional definitions such as ethnicity, language and religion. Most respondents had experienced positive results working with health care interpreters, although at times, this was a challenge for the family as they preferred privacy and the use of family members as interpreters. Another commonly reported challenge was the limited availability of reliable, culturally appropriate translated resources. Some participants expressed concern that learning theories about specific cultures may lead to stereotypes and that opportunities for formal cultural competence training were limited. Recommendations for practice include the targeting of educational resources to meet the needs of a diverse community and placing cultural competence on the agenda for ongoing training and maintenance of professional standards for clinical genetics practitioners to avoid the current ad hoc approach.

We are interested in the kind of knowledge that is particularly relevant to caring practice and the way in which qualitative research findings can serve such knowledge. As phenomenological researchers we have been engaged with the question of how findings from such research can be re-presented and expressed more aesthetically. Such a movement towards a more aesthetic phenomenology may serve the communicative concern to express phenomena relevant to caring practice in ways that appeal to the 'head, hand and heart'. The paper first offers some thoughts about the complex kind of knowledge relevant to caring that is not only technical or propositional, but actionable and aesthetically moving as well. We call this kind of knowledge 'embodied relational understanding'. Further, the paper outlines the development of one way of serving a more aesthetic phenomenology whereby research findings can be faithfully and evocatively translated into more empathically impactful expressions. We call this process 'embodied interpretation'. It is guided by an epistemological framework grounded in the philosophies of Gadamer and Gendlin. We finally illustrate the process with reference to the experience of living after Stroke, and consider the value of this translational process for nursing education and practice.

Astronomy is rapidly approaching an impasse: very large datasets require remote or cloud-based parallel processing, yet many astronomers still try to download the data and develop serial code locally. Astronomers understand the need for change, but the hurdles remain high. We are developing a data archive designed from the ground up to simplify and encourage cloud-based parallel processing. While the volume of data we host remains modest by some standards, it is still large enough that download and processing times are measured in days and even weeks. We plan to implement a python based, notebook-like interface that automatically parallelises execution. Our goal is to provide an interface sufficiently familiar and user-friendly that it encourages the astronomer to run their analysis on our system in the cloud-astroinformatics as a service. We describe how our system addresses the approaching impasse in astronomy using the SAMI Galaxy Survey as an example.

The beauty and splendour of astronomical images has made an enormously positive impact with the media and public alike. As a leading provider of astronomical imagery and a major contributor of Hubble Space Telescope press release images, the outreach division of the Space Telescope Science Institute (STScI) recognizes the importance of making press release images compliant with Virtual Observatory standards for inclusion in databases and repositories. A small working group has been formed to define and evaluate the procedures for making outreach images accessible by Virtual Observatory applications, and more specifically, to establish a World Coordinate System (WCS) for these images, which so far have none. We report on the status of various software techniques that can be used to transform coordinates on images easily and accurately, using reference images and astronomical star catalogues when available.

Burdensome symptoms and potentially inappropriate care practices are common at the end of life for nursing home residents. Appropriately managing symptoms and limiting aggressive care practices is key to high-quality end-of-life care. Little research is available, however, on the opinions of nursing home care providers about the impact of symptoms and practices for both residents and care facilities. Our objectives were to (1) identify common burdensome symptoms and potentially inappropriate practices at the end of life for nursing home residents, (2) develop and assess the feasibility of a procedure to have various groups of nursing home care providers rate impact of symptoms and practices, and (3) generate recommendations for action and further research, with key policy and decision makers. Proof-of-concept study. Partnered research by researchers, health professionals, and decision makers to identify and explore the impact of burdensome symptoms and potentially inappropriate care practices for nursing home residents at the end of life. Thirty-six nursing homes from Alberta, Manitoba, and Saskatchewan. A total of 6007 residents (prevalence rating); 4 medical directors, 5 directors of care, 4 nurse practitioners, 4 registered nurses, 5 licensed practical nurses, 5 care aides (impact rating); and 13 key policy or decision makers from Alberta, British Columbia, and Manitoba (expert panel). Based on a literature search and data in the Resident Assessment Instrument-Minimum Data Set (RAI-MDS) 2.0, we generated lists of burdensome symptoms and potentially inappropriate care practices for nursing home residents at the end of life. We rated prevalence of those symptoms and practices in the last quarter before death as high, medium, or low. Care providers rated the burden of symptoms and inappropriateness of practices as high, medium, or low. Directors of care rated the unnecessary cost of those symptoms and practices to a nursing home as high, medium, or low. We ranked
A cost-effectiveness analysis of provider interventions to improve health worker practice in providing treatment for uncomplicated malaria in Cameroon: a study protocol for a randomized controlled trial
Full Text Available Abstract Background Governments and donors all over Africa are searching for sustainable, affordable and cost-effective ways to improve the quality of malaria case management. Widespread deficiencies have been reported in the prescribing and counselling practices of health care providers treating febrile patients in both public and private health facilities. Cameroon is no exception with low levels of adherence to national guidelines, the frequent selection of non-recommended antimalarials and the use of incorrect dosages. This study evaluates the effectiveness and cost-effectiveness of introducing two different provider training packages, alongside rapid diagnostic tests (RDTs, designed to equip providers with the knowledge and practical skills needed to effectively diagnose and treat febrile patients. The overall aim is to target antimalarial treatment better and to facilitate optimal use of malaria treatment guidelines. Methods/Design A 3-arm stratified, cluster randomized trial will be conducted to assess whether introducing RDTs with provider training (basic or enhanced is more cost-effective than current practice without RDTs, and whether there is a difference in the cost effectiveness of the provider training interventions. The primary outcome is the proportion of patients attending facilities that report a fever or suspected malaria and receive treatment according to malaria guidelines. This will be measured by surveying patients (or caregivers as they exit public and mission health facilities. Cost-effectiveness will be presented in terms of the primary outcome and a range of secondary outcomes, including changes in provider knowledge. Costs will be estimated from a societal and provider perspective using standard economic evaluation methodologies. Trial Registration ClinicalTrials.gov: NCT00981877

Despite its appearing to be a simple question to answer, there has been no consensus as to whether or not the alignments of ancient Greek temples reflect astronomical intentions. Here I present the results of a survey of archaic and classical Greek temples in Sicily and compare them with temples in Greece. Using a binomial test I show strong evidence that there is a preference for solar orientations. I then speculate that differences in alignment patterns between Sicily and Greece reflect differing pressures in the expression of ethnic identity.

Future astronomical telescopes in space will have architectures with complex and demanding requirements in order to meet their science goals. The missions currently being studied by NASA for consideration in the next Decadal Survey range in wavelength from the X-ray to Far infrared; examining phenomenon from imaging exoplanets and characterizing their atmospheres to detecting gravitational waves. These missions have technical challenges that are near or beyond the state of the art from the telescope to the detectors. This paper describes some of these challenges and possible solutions. Promising measurements and future demonstrations are discussed that can enhance or enable these missions.

Le Verrier was a superb scientist. His discovery of Neptune in 1846 made him the most famous astronomer of his time. He produced a complete theory of the motions of the planets which served as a basis for planetary ephemeris for a full century. Doing this, he discovered an anomaly in the motion of Mercury which later became the first proof of General Relativity. He also founded European meteorology. However his arrogance and bad temper created many enemies, and he was even fired from his position of Director of the Paris Observatory.

A liquid-helium-cooled far infrared spectrophotometer was built and used to make low resolution observations of the continua of several kinds of astronomical objects using the Kuiper Airborne Observatory. This instrument fills a gap in both sensitivity to continuum sources and spectral resolution between the broadband photometers with lambda/Delta lambda approximately 1 and spectrometers with lambda/Delta lambda greater than 50. While designed primarily to study planetary nebulae, the instrument permits study of the shape of the continua of many weak sources which cannot easily be observed with high resolution systems.

Students are the lifeblood of astronomy, the next generation of astronomers. While other scientific disciplines are facing declining student enrollments, the ASTRONET strategic plan for European Astronomy notes “young students have continued to enter the field at a steady level”. Indeed, with Very Large Telescope (VLT), Atacama Large Millimeter/submillimeter Array (ALMA) the European Extremely Large Telescope (E-ELT) and other exciting new facilities on the horizon, it is hard to imagine a better time to be an astronomy student.
Originally published in English in 1973. This volume traces the development of the revolution which so drastically altered man's view of the universe in the sixteenth and seventeenth centuries. The ""astronomical revolution"" was accomplished in three stages, each linked with the work of one man. With Copernicus, the sun became the centre of the universe. With Kepler, celestial dynamics replaced the kinematics of circles and spheres used by Copernicus. With Borelli the unification of celestial and terrestrial physics was completed by abandonment of the circle in favour the straight line to inf

An ancient observatory was unearthed recently at Taosi site. This paper discussed the figure of the relic, analyzed the relationship between the 12 backsights and calendar date using astronomical method, and compared the simulated observation with theoretic computation. The investigation shows that backsight E2---E12 indicated the directions of sunrise in the whole year, which were roughly equally distributed and offered an unequal calendar system. The backsight E1 indicated the south-end of the moonrise, giving a time symbol of 18---19 years. This building must be a complex of solar observation, time service, solar worship, and sacrificial ritual

Obtaining interesting celestial objects from tens of thousands or even millions of recorded optical-ultraviolet spectra depends not only on the data quality but also on the accuracy of spectra decomposition. Additionally rapidly growing data volumes demands higher computing power and/or more efficient algorithms implementations. In this paper we speed up the process of substracting iron transitions and fitting Gaussian functions to emission peaks utilising C++ and OpenCL methods together with the NOSQL database. In this paper we implemented typical astronomical methods of detecting peaks in comparison to our previous hybrid methods implemented with CUDA.

Full Text Available Abstract Background Research evidence is not always being disseminated to healthcare providers who need it to inform their clinical practice. This can result in the provision of ineffective services and an inefficient use of resources, the implications of which might be felt particularly acutely in low- and middle-income countries. Malaria prevention is a particularly compelling domain to study evidence/practice gaps given the proven efficacy, cost-effectiveness and disappointing utilization of insecticide-treated nets (ITNs. Methods This study compares what is known about ITNs to the related knowledge and practices of healthcare providers in four low- and middle-income countries. A new questionnaire was developed, pilot tested, translated and administered to 497 healthcare providers in Ghana (140, Laos (136, Senegal (100 and Tanzania (121. Ten questions tested participants' knowledge and clinical practice related to malaria prevention. Additional questions addressed their individual characteristics, working context and research-related activities. Ordinal logistic regressions with knowledge and practices as the dependent variable were conducted in addition to descriptive statistics. Results The survey achieved a 75% response rate (372/497 across Ghana (107/140, Laos (136/136, Senegal (51/100 and Tanzania (78/121.

Observations taken with ground-based astronomical telescopes are affected by various airglow emission processes in the Earth's upper atmosphere. This chemiluminescent emission can be used to investigate the physical state of the meso- and the thermosphere. By applying a modified approach of techniques originally developed to characterise and remove these features from the astronomical spectra, which are not primarily taken for airglow studies, these spectra are suitable for airglow research. For our studies, we currently use data from two observing sites on both hemispheres for our studies: The European Southern Observatory operates four 8m telescopes at the Very Large Telescope (VLT) in the Chilean Atacama desert (24.6°S, 70.4°W). The 2.5m Sloan Digital Sky Survey telescope (SDSS) located in New Mexico/USA (32.8°N, 105.8°W) provides observations from the northern hemisphere. Each of these telescopes is equipped with several astronomical instruments. Among them are several spectrographs operating in the optical and near-IR regime with medium to high spectral resolution. Currently, we work on data from the following three spectrographs (1) UVES@VLT (Ultraviolet and Visual Echelle Spectrograph): This instrument provides spectra in the wavelength regime from 0.3 to 1.1μm in small spectral ranges. Its high resolving power (up to R˜110 000) allows a detailed study of oxygen (OI@557nm, OI@630nm), sodium (NaD@589nm), nitrogen (NI@520nm), and many OH bands. UVES has been in operation since 1999 providing the longest time series. (2) X-Shooter@VLT: This spectrograph is unique as it provides the whole wavelength range from 0.3 to 2.5μm at once with medium resolving power (R˜3 300 to 18 000, depending on the setup). This enables us to study the dependency of optical and near-IR airglow processes simultaneously, e.g. the OH bands. In addition, weak airglow continuum emission, e.g. arising from FeO and NiO can be studied. In operation since 2009, the data cover half a

Handoffs are communication processes that enact the transfer of responsibility between providers across clinical settings. Prior research on handoff communication has focused on inpatient settings between provider teams and has emphasized patient safety. This study examines handoff communication within multidisciplinary provider teams in two outpatient settings. To conduct an exploratory study that describes handoff communication among multidisciplinary providers, to develop a theory-driven descriptive framework for outpatient handoffs, and to evaluate the strengths and weaknesses of different handoff types. Qualitative, in-depth, semi-structured interviews with 31 primary care, mental health, and social work providers in two Department of Veterans Affairs (VA) Medical Center outpatient clinics. Audio-recorded interviews were transcribed and analyzed using Grounded Practical Theory to develop a theoretical model of and a descriptive framework for handoff communication among multidisciplinary providers. Multidisciplinary providers reported that handoff decisions across settings were made spontaneously and without clear guidelines. Two situated values, clinic efficiency and patient-centeredness, shaped multidisciplinary providers' handoff decisions. Providers reported three handoff techniques along a continuum: the electronic handoff, which was the most clinically efficient; the provider-to-provider handoff, which balanced clinic efficiency and patient-centeredness; and the collaborative handoff, which was the most patient-centered. Providers described handoff choice as a practical response to manage constituent features of clinic efficiency (time, space, medium of communication) and patient-centeredness (information continuity, management continuity, relational continuity, and social interaction). We present a theoretical and descriptive framework to help providers evaluate differential handoff use, reflect on situated values guiding clinic communication, and guide
characteristics are listed in great detail. Two are small and dense and the outermost is gaseous. It turns out that the distance to our Earth is 26 light-years and that it would be not be too easy to observe the Ikaros system from here. It is unlikely that life can develop in this planetary system during the relatively short lifetime of the central star. United Kingdom: Mr. Michael Ching, Mr. Richard Field (Teacher) (Oundle School, Peterborough) This project is directed towards variable stars of the pulsating type. It discusses the theory for these pulsations and the peculiar location of these types of stars in the HR-diagramme, as well as the technique to determine distances by means of measurements of the period. Once the period has been found observationally, the Period-Luminosity diagram makes is possible to find the luminosity and hence the distance to the star. The project also involved real measurements of an RR Lyr-type variable with a period of about 1/3 day. For this, a phototransitor and a registering device were used. The expected light variations were clearly seen. Addendum 2 A brief summary of the results obtained at ESO This brief description is based on the provisional data reduction and subsequent interpretation by the six teams, as presented during a final session on November 20, 1995. Further work will allow to quantify the results in greater detail. Each team was guided by a young ESO astronomer as Team Leader and was also provided support during the observations by ESO-astronomers Lex Kaper and Marcus Kissler, as well as by night assistants Vicente Reyes and Jesus Rodriguez (Garching), Hernan Nunez, Jorge Miranda and Victor Merino at (La Silla). For the data reduction, the teams used the MIDAS image processing system; the introduction was provided by Rein Warmels, one of ESO's experts on these matters. Since the teams that were observing during the last night (3A and 3B) had very little time to reduce and interpret their data, it was not possible to carry

To evaluate two psychometric properties of the French versions of the Evidence-Based Practice Beliefs and Evidence-Based Practice Implementation scales, namely their internal consistency and construct validity. The Evidence-Based Practice Beliefs and Evidence-Based Practice Implementation scales developed by Melnyk et al. are recognised as valid, reliable instruments in English. However, no psychometric validation for their French versions existed. Secondary analysis of a cross sectional survey. Source data came from a cross-sectional descriptive study sample of 382 nurses and other allied healthcare providers. Cronbach's alpha was used to evaluate internal consistency, and principal axis factor analysis and varimax rotation were computed to determine construct validity. The French Evidence-Based Practice Beliefs and Evidence-Based Practice Implementation scales showed excellent reliability, with Cronbach's alphas close to the scores established by Melnyk et al.'s original versions. Principal axis factor analysis showed medium-to-high factor loading scores without obtaining collinearity. Principal axis factor analysis with varimax rotation of the 16-item Evidence-Based Practice Beliefs scale resulted in a four-factor loading structure. Principal axis factor analysis with varimax rotation of the 17-item Evidence-Based Practice Implementation scale revealed a two-factor loading structure. Further research should attempt to understand why the French Evidence-Based Practice Implementation scale showed a two-factor loading structure but Melnyk et al.'s original has only one. The French versions of the Evidence-Based Practice Beliefs and Evidence-Based Practice Implementation scales can both be considered valid and reliable instruments for measuring Evidence-Based Practice beliefs and implementation. The results suggest that the French Evidence-Based Practice Beliefs and Evidence-Based Practice Implementation scales are valid and reliable and can therefore be used to

In the Manchurian province of Liaoning, near 41N19' and 119E30', exist ruins of a middle Neolithic society (2500 to 4000 BC) known as the Hongshan culture. This location, called Niuheliang, is comprised of 16 locations with monumental structures scattered over 80 square kilometers of hills. Most are stone burial structures that contain jade artifacts implying wealth and power. One structure is unique in being unusually shaped and containing oversized effigies of goddess figures. This structure also has a commanding view of the surrounding landscape. The presence of decorated pottery, jade and worked copper suggests the Hongshan people were sophisticated artisans and engaged in long-distance trading. During 1997, we've conducted a course at Denver as part of our Core Curriculum program for upper division students, that has examined the astronomical and cultural aspects of the Niuheliang site, to attempt to determine whether these contemporaries of the builders of Stonehenge may have included astronomical alignments into their constructions. The preliminary result of our studies suggests that certain monuments have potential for lunar standstill observation from the "goddess temple".

Researchers using the National Science Foundation's Very Large Array (VLA) radio telescope have imaged a "spectacular and complex structure" in a galaxy 50 million light-years away. Their work both resolves a decades-old observational mystery and revises current theories about the origin of X-ray emission coming from gas surrounding the galaxy. The new VLA image is of the galaxy M87, which harbors at its core a supermassive black hole spewing out jets of subatomic particles at nearly the speed of light and also is the central galaxy of the Virgo Cluster of galaxies. The VLA image is the first to show detail of a larger structure that originally was detected by radio astronomers more than a half-century ago. Analysis of the new image indicates that astronomers will have to revise their ideas about the physics of what causes X-ray emission in the cores of many galaxy clusters. Frazer Owen of the National Radio Astronomy Observatory (NRAO) in Socorro, NM; Jean Eilek of the New Mexico Institute of Mining and Technology (NM Tech) in Socorro, NM; and Namir Kassim of the Naval Research Laboratory in Washington, DC, announced their discovery at the American Astronomical Society's meeting today in Austin, TX. The new observations show two large, bubble-like lobes, more than 200,000 light-years across, that emit radio waves. These lobes, which are intricately detailed, apparently are powered by gravitational energy released from the black hole at the galaxy's center. "We think that material is flowing outward from the galaxy's core into these large, bright, radio-emitting 'bubbles,'" Owen said. The newly-discovered "bubbles" sit inside a region of the galaxy known to be emitting X-rays. Theorists have speculated that this X-ray emission arises when gas that originally was part of the Virgo Cluster of galaxies, cools and falls inwards onto M87 itself, at the center of the cluster. Such "cooling flows" are commonly thought to be responsible for strong X-ray emission in many
Curricular Astronomy is taught in Moldavia , except Transnistria and Gagauzia, in the final (11th class) of the secondary schools and gymnasiums, and in the 12th class of the lyceums. The program takes 35 academic hours. The basic book is by Vorontsov-Veliaminov, used in the former USSR, but the Romanian one is also used, in spite of many criticisms addressed to both by our astronomy teachers. In Transinstria (on the left of the Dniester river)astronomy is taught 17 hours. Extracurricular activities develop at the Real Lyceum, where students and amateur astronomers carry out regular observations. Particularly, photographs of the comet Hale-Bopp have been realized using a Cassegrain 450 mm telescope by young astronomers under supervision of S. Luca and D. Gorodetzky (Gorodetchi). Except the telescope from the Real Lyceum other few telescopes are in construction. Unfortunately, no planetarium exists now in Chisinau, since the old one was returned to church. Astronomy courses are taught at the physical and mathematical departments of the Pedagogical University, Transnistrian Moldavian University in Tiraspol and the State University of |Moldavia. Many efforts were made by the State University lecturers and scientists to popularize Astronomy and Astrophysics in the books and in the press, at the radio and TV. No astronomy is taught at the Gagauzian National University in Comrat. No astronomiucal departments exist in Universities of |Moldavia.

Soon after you begin studying the sky through your small telescope or binoculars, you will probably be encouraged by others to make sketches of what you see. Sketching is a time-honored tradition in amateur astronomy and dates back to the earliest times, when telescopes were invented. Even though we have lots of new imaging technologies nowadays, including astrophotography, most observers still use sketching to keep a record of what they see, make them better observers, and in hopes of perhaps contributing something to the body of scientific knowledge about the Moon. Some even sketch because it satisfies their artistic side. The Moon presents some unique challenges to the astronomer-artist, the Moon being so fond of tricks of the light. Sketching the Moon: An Astronomical Artist’s Guide, by five of the best lunar observer-artists working today, will guide you along your way and help you to achieve really high-quality sketches. All the major types of lunar features are covered, with a variety of sketching te...
This paper covers some aspects of the scientific life of Harvey Butcher who was the Director of the Research School for Astronomy and Astrophysics at the Australian National University in Canberra from September 2007 to January 2013. He has made significant contributions to research on the evolution of galaxies, nucleosynthesis, and on the design and implementation of advanced astronomical instrumentation including LOFAR (Low Frequency Array Radio telescope). He is well known for his discovery of the Butcher-Oemler effect. Before coming to Australia he was the Director of the Netherlands Foundation for Research in Astronomy from September 1991 to January 2007. In 2005 he was awarded a Knighthood in the Order of the Netherlands Lion for contributions to interdisciplinary science, innovation and public outreach.This paper is based on an interview conducted by the author with Harvey Butcher for the National Project on Significant Australian Astronomers sponsored by the National Library of Australia. Except otherwise stated, all quotations used in this paper are from the Butcher interview which has been deposited in the Oral History Archives of the National Library.
Astronomers studying archival data from an Australian radio telescope have discovered a powerful, short-lived burst of radio waves that they say indicates an entirely new type of astronomical phenomenon.

CREDIT: Lorimer et al., NRAO/AUI/NSF Click on image for high-resolution file ( 114 KB) "This burst appears to have originated from the distant Universe and may have been produced by an exotic event such as the collision of two neutron stars or the death throes of an evaporating black hole," said Duncan Lorimer, Assistant Professor of Physics at West Virginia University (WVU) and the National Radio Astronomy Observatory (NRAO). The research team led by Lorimer consists of Matthew Bailes of Swinburne University in Australia, Maura McLaughlin of WVU and NRAO, David Narkevic of WVU, and Fronefield Crawford of Franklin and Marshall College in Lancaster, Pennsylvania. The astronomers announced their findings in the September 27 issue of the online journal Science Express. The startling discovery came as WVU undergraduate student David Narkevic re-analyzed data from observations of the Small Magellanic Cloud made by the 210-foot Parkes radio telescope in Australia. The data came from a survey of the Magellanic Clouds that included 480 hours of observations. "This survey had sought to discover new pulsars, and the data already had been searched for the type of pulsating signals they produce," Lorimer said. "We re-examined the data, looking for bursts that, unlike the usual ones from pulsars, are not periodic," he added. The survey had covered the Magellanic Clouds, a pair of small galaxies in orbit around our own Milky Way Galaxy. Some 200,000 light-years from Earth, the Magellanic Clouds are prominent features in the Southern sky. Ironically, the new discovery is not part of these galaxies, but rather is much more distant

Data sets in astronomy are growing to enormous sizes. Modern astronomical surveys provide not only image data but also catalogues of millions of objects (stars, galaxies), each object with hundreds of associated parameters. Exploration of this very high-dimensional data space poses a huge challenge.

Little is known about how electronic mail (e-mail) is currently used in oncology practice to facilitate patient care. The objective of our study was to understand the current e-mail practices and preferences of patients and physicians in a large comprehensive cancer center. Separate cross-sectional surveys were administered to patients and physicians (staff physicians and clinical fellows) at the Princess Margaret Cancer Centre. Logistic regression was used to identify factors associated with current e-mail use. Record review was performed to assess the impact of e-mail communication on care. The survey was completed by 833 patients. E-mail contact with a member of the health care team was reported by 41% of respondents. The team members contacted included administrative assistants (52%), nurses (45%), specialist physicians (36%), and family physicians (18%). Patient factors associated with a higher likelihood of e-mail contact with the health care team included younger age, higher education, higher income, enrollment in a clinical trial, and receipt of multiple treatments. Eighty percent of physicians (n = 63 of 79) reported previous contact with a patient via e-mail. Physician factors associated with a greater likelihood of e-mail contact with patients included older age, more senior clinical position, and higher patient volume. Nine hundred sixty-two patient records were reviewed, with e-mail correspondence documented in only 9% of cases. E-mail is commonly used for patient care but is poorly documented. The use of e-mail in this setting can be developed with appropriate guidance; however, there may be concerns about widening the gap between certain groups of patients.

One of the most important cities of Romania is Cluj-Napoca (Kolozsvár, Klausenburg). This is a traditional center of education, with many universities and high schools. From the second half of the 18th century the University of Cluj has its own Astronomical Observatory, serving for didactical activities and scientific researches. The famous astronomer Maximillian Hell was one of those Jesuits who put the base of this Astronomical Observatory. Our purpose is to offer a short history of the beginnings of this Astronomical Observatory.

A questionnaire was mailed to 148 publicly and privately supported academic health sciences libraries affiliated with Association of American Medical Colleges (AAMC)–accredited medical schools in the United States and Canada to determine level of access and services provided to the general public. For purposes of this study, “general public” was defined as nonaffiliated students or health care professionals, attorneys and other nonhealth-related professionals, patients from affiliated or other hospitals or clinics, and general consumers. One hundred five (71%) libraries responded. Results showed 98% of publicly supported libraries and 88% of privately supported libraries provided access to some or all of the general public. Publicly supported libraries saw greater numbers of public patrons, often provided more services, and were more likely to circulate materials from their collections than were privately supported libraries. A significant number of academic health sciences libraries housed a collection of consumer-oriented materials and many provided some level of document delivery service, usually for a fee. Most allowed the public to use some or all library computers. Results of this study indicated that academic health sciences libraries played a significant role in serving the information-seeking public and suggested a need to develop written policies or guidelines covering the services that will be provided to minimize the impact of this service on primary clientele.

The objective of this study was to explore Somali mothers’ beliefs and practices around infant feeding and education, towards developing a culturally informed infant nutrition curriculum for health providers. Four focus groups were conducted to explore: (1) beliefs about infant feeding, hunger and ideal weight; (2) feeding practices; (3) nutrition education approaches; and (4) provider/mother interactions. Thirty-seven Somali mother participants identified the following themes within these topics: (1) strategies for assessing hunger, satiety and when to feed; shared beliefs that plump babies are healthy, leading to worry about infant weight; (2) context of breast milk adequacy, difficulties breastfeeding and environmental and cultural barriers to breastfeeding, leading to nearly universal early supplementation with formula; (3) preferred education approaches include provider visits with interpreters, Somali language educational materials and advice from older, experienced family members; and (4) desired health provider skills include: listening, explaining, empathy, addressing specific concerns, repeating important information, offering preventive advice and sufficient visit time. This study presents knowledge about Somali beliefs and practices that can directly guide discussions with these families. Given that these infants appear on a trajectory towards obesity, influencing infant feeding practices in the Somali community is a good upstream approach to preventing obesity. These findings will underpin a new infant nutrition curriculum for health providers. PMID:20055931

A theoretical and practical inquiry into the teaching of spatial thinking in college astronomy classes is reported. After examining some of the historical background of the discipline of astronomy, the author investigates some of the pedagogical implications of the implicit visual grammar so effortlessly utilized by astronomers and yet so apparently difficult for many students to employ. These pedagogical implications were implemented in the design of a study of one astronomy section of an introductory college astronomy course. Tutorial visual exercises using eyes-on models and diagrams seemed to be very useful for student apprehension of certain tagged items, but overall spatial learning seems to be more a product of general class environment than a matter of specific exercises per se. Some promising pedagogical strategies involving direct visual treatments to improve students' visual skills and iconic repertoire are discussed. Certain astronomical "primitives" involving astronomical distance determinations and projective relationships are explored in depth. Visual models are very useful, but students must be continually reminded of the implicit importance of the great distances appropriate to astronomical discourse. Likewise, in discussing photographs and diagrams, many students must be explicitly shown and taught the projective properties of ellipses, spheres and circles. Analogies with other findings which treat student misconceptions in science are pursued, but the focus of this study pertains more to certain visual predispositions than to firmly held beliefs.

The continuing rise of obesity among Latinos is a public health concern with an immediate need for early prevention. Changes in family structures have increased demand and reliance for child care for young children. Latino children are the fastest-growing segment of the child population in the United States, and research shows that Latino families use preschools and day care centers much less than those of other ethnic groups, apparently because of cultural preferences for family-like care. Given that many low income Latino children attend family child care homes (FCCHs), there is a need to explore the role that FCCH providers may play in establishing and reinforcing children's early healthful eating and physical activity behaviors and consequently in the prevention of childhood obesity. Using purposive sampling, six focus groups were conducted in Spanish with licensed Latino FCCH providers (n = 44). Data was analyzed to identify recurrent themes. Latino FCCH providers described how they play an influential role in promoting healthful eating and physical activity behaviors of preschool children in their care. They also identified many barriers and challenges in establishing and maintaining healthful nutrition and physical activity behaviors, including high cost of healthy foods, cold weather, and physical environment of FCCH. Latino FCCH providers can have a strong impact in promoting healthful behaviors in low-income, Latino communities. They may be able to effectively deliver interventions targeting low-income, minority families to promote healthful eating and physical activity behaviors and prevent child obesity.

The population of adolescents and young adults (AYA) with perinatally-acquired HIV (PHIV) present challenges to HIV healthcare providers (HHCPs). Originally not expected to survive childhood, they are now living well into young adulthood. Little is known about the type of sexual and reproductive (SRH) information/services offered to AYA with PHIV by HHCPs. HHCPs (n=67) were recruited using snowball sampling, and completed an online survey. Providers' most frequently endorsed SRH topics discussed with both male and female patients included condom use (77.3%), STD prevention (73.1%), and screening (62.1%). Providers' reports indicated that females received significantly more education about SRH topics overall. The most frequently noted barriers to SRH communication included more pressing health concerns (53.0%), parent/guardian not receptive (43.9%), and lack of time during appointment (43.9%). Provider-reported SRH conversations with HHCPs were highly focused on horizontal transmission and pregnancy prevention. Salient social aspects of SRH promotion for AYAs with PHIV (e.g., managing disclosure and romantic relationships) were less commonly discussed, though such conversations may serve to reduce secondary transmission and enhance the overall well-being of AYA with PHIV. Findings indicated that further work must be done to identify strategies to address unmet SRH needs of the aging population of AYA with PHIV.

Artemisinin combination therapy (ACT) has been the first-line treatment for uncomplicated malaria in Cameroon since 2004 and Nigeria since 2005, though many febrile patients receive less effective antimalarials. Patients often rely on providers to select treatment, and interventions are needed to improve providers' practice and encourage them to adhere to clinical guidelines. Providers' adherence to malaria treatment guidelines was examined using data collected in Cameroon and Nigeria at public and mission facilities, pharmacies and drug stores. Providers' choice of antimalarial was investigated separately for each country. Multilevel logistic regression was used to determine whether providers were more likely to choose ACT if they knew it was the first-line antimalarial. Multiple imputation was used to impute missing data that arose when linking exit survey responses to details of the provider responsible for selecting treatment. There was a gap between providers' knowledge and their practice in both countries, as providers' decision to supply ACT was not significantly associated with knowledge of the first-line antimalarial. Providers were, however, more likely to supply ACT if it was the type of antimalarial they prefer. Other factors were country-specific, and indicated providers can be influenced by what they perceived their patients prefer or could afford, as well as information about their symptoms, previous treatment, the type of outlet and availability of ACT. Public health interventions to improve the treatment of uncomplicated malaria should strive to change what providers prefer, rather than focus on what they know. Interventions to improve adherence to malaria treatment guidelines should emphasize that ACT is the recommended antimalarial, and it should be used for all patients with uncomplicated malaria. Interventions should also be tailored to the local setting, as there were differences between the two countries in providers' choice of antimalarial

Over the past four years we have seen continued advancement in network technology and how those technologies are beginning to enable astronomical science. Even though some sociological aspects are hindering full cooperation between most observatories and telescopes outside of their academic or institutional connections, an unprecedented step during the summer of 2005 was taken towards creating a world-wide interconnection of astronomical assets. The Telescope Alert Operations Network System (TALONS), a centralized server/client bi-directional network developed and operated by Los Alamos National Laboratory, integrated one of its network nodes with a node from the eScience Telescopes for Astronomical Research (eSTAR), a peer-to-peer agent based network developed and operated by The University of Exeter. Each network can act independently, providing support for their direct clients, and by interconnection provide local clients with access to; outside telescope systems, software tools unavailable locally, and the ability to utilize assets far more efficiently, thereby enabling science on a world-wide scale. In this paper we will look at the evolution of these independent networks into the worlds first heterogeneous telescope network and where this may take astronomy in the future. We will also examine those key elements necessary to providing universal communication between diverse astronomical networks.

This study explores the prevalence and provider- and practice-related correlates of physician recommendation and administration of the quadrivalent human papillomavirus (HPV) vaccine, Gardasil, to 11- to 12-year-old girls and the intention to recommend the HPV vaccine to 11- to 12-year-old boys in Georgia. The study also describes physician knowledge about and barriers to HPV vaccination. This cross-sectional study was conducted from December 2010 to February 2011. The study sample was drawn using the Georgia Vaccines for Children (VFC) provider list as a sampling frame and probability 1-stage cluster sampling with counties as clusters. The final analytic sample was restricted to 206 provider locations. Weighted percentages and corresponding statistics were calculated accounting for selection probabilities, nonresponse, and the cluster sample design. Among Georgia VFC providers attending to 11- to 12-year-old girls, 46% had always recommended that their patients get the HPV vaccination and 41% had vaccinated their female patients. Among Georgia VFC providers attending to 11- to 12-year-old boys, 20% would always recommend that their male patients get vaccinated.Physicians most frequently endorsed costs of stocking the vaccine (73%), upfront costs (69%), vaccination (68%), and insurance reimbursements (63%) as barriers to their HPV vaccination practices. Despite the Advisory Committee on Immunization Practices' recommendations on HPV vaccination, the prevalence of recommending and administering the HPV vaccine to female and male patients, aged 11 to 12 years, by VFC providers is an ongoing challenge in Georgia.

Full Text Available Zoonoses are common causes of human and livestock illness in Tanzania. Previous studies have shown that brucellosis, leptospirosis, and Q fever account for a large proportion of human febrile illness in northern Tanzania, yet they are infrequently diagnosed. We conducted this study to assess awareness and knowledge regarding selected zoonoses among healthcare providers in Moshi, Tanzania; to determine what diagnostic and treatment protocols are utilized; and obtain insights into contextual factors contributing to the apparent under-diagnosis of zoonoses.We conducted a questionnaire about zoonoses knowledge, case reporting, and testing with 52 human health practitioners and 10 livestock health providers. Immediately following questionnaire administration, we conducted semi-structured interviews with 60 of these respondents, using the findings of a previous fever etiology study to prompt conversation. Sixty respondents (97% had heard of brucellosis, 26 (42% leptospirosis, and 20 (32% Q fever. Animal sector respondents reported seeing cases of animal brucellosis (4, rabies (4, and anthrax (3 in the previous 12 months. Human sector respondents reported cases of human brucellosis (15, 29%, rabies (9, 18% and anthrax (6, 12%. None reported leptospirosis or Q fever cases. Nineteen respondents were aware of a local diagnostic test for human brucellosis. Reports of tests for human leptospirosis or Q fever, or for any of the study pathogens in animals, were rare. Many respondents expressed awareness of malaria over-diagnosis and zoonoses under-diagnosis, and many identified low knowledge and testing capacity as reasons for zoonoses under-diagnosis.This study revealed differences in knowledge of different zoonoses and low case report frequencies of brucellosis, leptospirosis, and Q fever. There was a lack of known diagnostic services for leptospirosis and Q fever. These findings emphasize a need for improved diagnostic capacity alongside healthcare

Despite the reported benefits of physical activity in alleviating the impact of cancer and its treatments, oncology care providers (OCPs) are not routinely discussing exercise with their patients, suggesting a knowledge to action gap. We sought to determine OCP's knowledge, beliefs, barriers, and facilitators to exercise discussion. A survey was administered to OCPs at the cancer center in Hamilton, Ontario. Questions comprised of demographics, knowledge and beliefs regarding exercise guidelines, and barriers and facilitators to exercise discussion. Analysis of survey responses was descriptive. Pearson's chi-squared test was used to examine select associations. There were 120 respondents (61% response rate) representing a diversity of professions. Approximately, 80% of OCPs were not aware of any exercise guidelines in cancer and self-reported poor knowledge on when, how, and which patients to refer to exercise programs. OCPs who reported meeting Canada's Physical Activity guidelines were significantly more likely to identify correct guidelines (p = 0.023) and to report good knowledge on how to provide exercise counseling (p = 0.014). Across OCP groups, barriers to exercise discussion included poor knowledge, lack of time, and safety concerns. Most felt that educational sessions and having an exercise specialist on the clinical team would be beneficial. OCPs have low knowledge regarding exercise counseling, but believe that discussing exercise is a multidisciplinary task and expressed a desire for further training. Interventions will require a multi-pronged approach including education for OCPs and guidance on assessment for exercise safety.

The use of routinely available electronic sources of healthcare data on the spread of influenza has the potential to enhance current surveillance activities. This study aimed to develop a method for identifying influenza-related records from general practitioner(GP) out-of-hours (OOH) services in Ireland. Data from one such service were interrogated for keywords relating to influenza-like illness (ILI) and a proxy measure of influenza activity in the community setting was developed. Comparison of this syndromic surveillance measure with national data on ILI consultation rates demonstrated a statistically significant temporal correlation.In five out of six influenza seasons investigated,peaks in the GP OOH influenza-related calls appeared at least one week ahead of peaks in the national ILI consultation rates. The method described in this paper has been extended to nine OOH services in Ireland (covering 70% of the Irish population) to provide weekly figures on self-reported illness for influenza in the community and its data have been incorporated into the national weekly influenza reports produced by the Health Protection Surveillance Centre. These data should provide early warnings of both seasonal and pandemic influenza in Ireland.

There is a pressing global need for trained and competent mental health clinicians to deliver evidence-based psychological therapies to millions of trauma survivors in need of care. Three model, large-scale training programs were initiated a decade ago, one in the United Kingdom (U.K.), and two in the United States (U.S.), to disseminate high-quality, evidence-based psychological care to traumatized children and adults in need of assistance. Milestone contributions to implementation science have been made by each of these training programs, although limitations and challenges remain to be considered. In contrast, culturally adapted and simplified PTSD interventions and therapy training programs have also been developed and tested during the past decade, three of which show particular promise for broader implementation. These simplified but evidence-based interventions have been developed for use by lay counsellors or health technicians with minimal or no prior mental health training. Finally, a growing range of technology-based and technology-assisted training models for PTSD providers have also been developed and disseminated in the past decade. This trend is expected to accelerate as more providers become accustomed to acquiring clinical training in this modality or format, although significant barriers to technology-based training will need to be overcome.

There is a growing body of evidence on the importance of work following a diagnosis of cancer and the need to provide better information, advice and related support to patients on work engagement. The aim of this study was to better understand the nature of those needs and to identify better ways to meet these for those with a urological cancer. The focus was on the issues that were common to three key stakeholder groups. Semi-structured interviews were conducted with stakeholders in North East Scotland: 12 individuals with kidney, bladder or prostate cancer, 10 healthcare providers and 10 managers from large organisations. Five key themes emerged from the Framework Analysis: perceived importance of work engagement; decision-making: treatment, work and cancer; roles and responsibilities; education and training; information, advice and support resources. The data confirmed that work engagement is important to those with urological cancer. It also made clear that the current provision of information and advice could be improved. Any such interventions should involve all three key stakeholder groups with greater clarity on their respective roles and responsibilities. Finally, any new system would be best integrated with existing care provision and supported by adequate education and training of those involved. © 2017 John Wiley & Sons Ltd.

Pisgah Astronomical Research Institute (PARI), a former NASA tracking station located in western North Carolina, has been offering programs, campus, and instrument use for undergraduate research and learning experiences since 2000. Over these years, PARI has collaborated with universities and colleges in the Southeastern U.S. Sharing its campus with institutions of higher learning is a priority for PARI as part of its mission to "to providing hands-on educational and research opportunities for a broad cross-section of users in science, technology, engineering and math (STEM) disciplines."PARI is a 200 acre campus for environmental, earth, geological, physical, and astronomical sciences. For example, the PARI 26-m and 4.6-m radio telescopes are excellent for teaching electromagnetic theory, spectroscopy, atomic and molecular emission processes, and general physics and astronomy concepts. The PARI campus has lab and office space, data centers with high speed internet, distance learning capabilities, radio and optical telescopes, earth science sensors, housing and cafeteria.Also, the campus is in an excellent spot for environmental and biological sciences lab and classroom experiences for students. The campus has the capability to put power and Internet access almost anywhere on its 200 acre campus so experiments can be set up in a protected area of a national forest. For example, Earthscope operates a Plate Boundary Observatory sensor on campus to measure plate tectonic motion. And, Clemson University has an instrument measuring winds and temperatures in the Thermsophere. The use of thePARI campus is limited only by the creativity faculty to provide a rich educational environment for their students. An overview of PARI will be presented along with a summary of programs, and a summary of undergraduate research experiences over the past 15 years. Access to PARI and collaboration possibilities will be presented.
Strasbourg Astronomical Observatory is quite an interesting place for historians: several changes of nationality between France and Germany, high-profile scientists having been based there, big projects born or installed in its walls, and so on. Most of the documents circulating on the history of the Observatory and on related matters have however been so far poorly referenced, if at all. This made necessary the compilation of a volume such as this one, offering fully-documented historical facts and references on the first decades of the Observatory history, authored by both French and German specialists. The experts contributing to this book have done their best to write in a way understandable to readers not necessarily hyperspecialized in astronomy nor in the details of European history. After an introductory chapter by the Editor, contributions by Wolfschmidt and by Duerbeck respectively deal extensively with the German periods and review people and instrumentation, while another paper by Duerbeck is more...
This is a personal account of how I became an astronomer. Fascinated by the stars and planets in the dark sky over Lolland, an island 100 km south of Copenhagen, the interest in astronomy was growing. Encouraged by my teachers, I polished mirrors and built telescopes with generous help from the local blacksmith and I observed light curves of variable stars. Studies at the Copenhagen University from 1950 gradually led me deeper into astronomy, especially astrometry (the astronomy of positions), guided by professor Bengt Str\\"omgren and my mentor dr. phil. Peter Naur. I was lucky to take part in the buildup of the new observatory at Brorfelde during the first difficult years and the ideas I gathered there have contributed to the two astrometry satellites Hipparcos and Gaia launched by the European Space Agency (ESA) in respectively 1989 and 2013.
It is surprising, but the fact is that the International Olympiads are often only combined with the competition, whereas the intercultural communication between the representatives of different nationalities and the expanding of ideologies of young people are the general-purpose components of not only in frames of the boundaries of scientific expertise, but also such communications, the Olympiads. Worldviews meeting and collaboration are driving forces of progress and play the most important role in the development of the modern science. Armenia participates in the International Astronomical Olympiads since 1997, and in the International Olympiads on Astronomy and Astrophysics since 2013. The Armenian team has always shown high results in competitions and is actively involved in cultural activities.
Our work is aimed at presenting Shirakatsi astronomical and natural philosophical views. Karl Anania Shirakatsi is classified as one of the world-class intellectual geniuses. He was endowed with exceptional talent and analyzing scientific understanding of natural phenomena. He refers his philosophical works to almost all fields of science, cosmography, mathematics, calendarology, historiography, etc. Shirakatsy's earnings of natural science and natural philosophy in medieval is too big He was the first prominent scholar and thinker of his time, creating a unique, comprehensive gitapilisopayakan system that still feeds the human mind. The scientific value of Shirakatsi has great importance not only for Armenians but also for the whole world of science, history, culture and philosophy. Shirakatsi can be considered not only national but also universal greatness.

Full Text Available The actual Romanian territory belongs to Carpatho-Danubian Space and to Ancient Europe. The Ancient European Society was a vast cultural entity based on a theocratic, matriarchal society, peaceful and art creating.Temples of Sarmizegetusa have given rise to several theories over time, proven by historians with the most diverse arguments. The largest complex of temples and sanctuaries was founded in Sarmizegetusa Regia, the Dacian’s main fortress and ancient capital of Dacia in the time of King Decebalus. The mysterious form of settlements has led researchers to the conclusion that the locations were astronomical observation shrines. Among the places of Dacian worship in Orastie Mountains the most impressive is the Great Circular Sanctuary, used to perform some celestial observations, and also as original solar calendar. This paper had the purpose to re-discover the Dacian Civilization and Dacian cosmogony based on the accumulated knowledge upon our country’s past.

Astronomy arises very early in a civilization and evolves as the civilization advances. It is therefore reasonable to assume that a vibrant knowledge of astronomy would have been a feature of a civilization the size of the Harappan Civilization. We suggest that structures dedicated to astronomy existed in every major Harappan city. One such city was Dholavira, an important trading port that was located on an island in what is now the Rann of Kutch during the peak of the Harappan Civilization. We have analyzed an unusual structure at Dholavira that includes two circular rooms. Upon assuming strategically-placed holes in their ceilings we examine the internal movement of sunlight within these rooms and suggest that the larger structure of which they formed a part could have functioned as an astronomical observatory.

We present cosmetic cleaning techniques for use with mainstream graphics software (Adobe Photoshop) to produce presentation-quality images and illustrations from astronomical data. These techniques have been used on numerous images from the Hubble Space Telescope when producing photographic, print and web-based products for news, education and public presentation as well as illustrations for technical publication. We expand on a previous paper to discuss the treatment of various detector-attributed artifacts such as cosmic rays, chip seams, gaps, optical ghosts, diffraction spikes and the like. While Photoshop is not intended for quantitative analysis of full dynamic range data (as are IRAF or IDL, for example), we have had much success applying Photoshop's numerous, versatile tools to final presentation images. Other pixel-to-pixel applications such as filter smoothing and global noise reduction will be discussed.
Davies, John; Robson, Ian; The Scientific Achievement of the United Kingdom InfraRed Telescope
These are the proceedings of an international meeting hosted by the Royal Observatory, Edinburgh, to commemorate the 30th anniversary of the dedication of the UKIRT, the United Kingdom InfraRed Telescope. The volume comprises 31 professional level papers. The first part of the book has 10 thorough reviews of the conception, design and build of the telescope, as well as accounts of some its key instruments such as IRCAM (the common-user infrared camera), CGS4 (the fourth Cooled Grating Spectrometer) and the Wide Field Camera. The second part of the book comprises 14 reviews of scientific achievements during its twenty years of visitor mode operations. The final part of the book is a series of 7 reviews of the results from the multiple surveys being done as part of UKIDSS (UKIRT Infrared Deep Sky Survey). The authors are all experts in their respective fields, for example instrument scientists, operations staff and leading astronomers.
We discuss the development and optimization of an ongoing educational project involving the whole population of the province of San Luis, Argentina. The core of the project includes activities and resources that capture formal curricular aspects directed towards all levels of teaching. The educational activities related to this project have been benefited by the acquisition of two planetariums made in Argentina, a MEADE 16'' telescope to be operated by remote control from any school-room in San Luis, and a naked-eye observatory with more than 30 pre-telescopic instruments, and other didactic tools specially designed for the teaching of Astronomy. Furthermore, an Internet site to upload all the astronomical activities suggested that has been developed along with a number of didactic and general-interest publications.
The work was originally published in 1961 under the title "La révolution astronomique" as part of the series, Histoire de la pensée. This book is an unabridged and unaltered republication of the English translation, by R. E. W. Maddison, originally published in 1973 (see 10.003.074). The author elucidates, precisely and in stages, the revolutionary ideas of Nicolaus Copernicus as well as the work of two other thinkers who made major contributions to the astronomical revolution: Johannes Kepler and Giovanni Borelli. He illuminates the exact contribution of each man, placing his work in its historical context and dispelling a host of misconceptions about it. In order to effectively recapture the ferment and flavor of the times, the author, whenever possible, has allowed Copernicus, Kepler and Borelli to speak for themselves by quoting key passages from their writings. Many of these passages were here translated for the first time.
The next generation of instruments for ground-based telescopes took a leap forward with the development of a new ultra-fast camera that can take 1500 finely exposed images per second even when observing extremely faint objects. The first 240x240 pixel images with the world's fastest high precision faint light camera were obtained through a collaborative effort between ESO and three French laboratories from the French Centre National de la Recherche Scientifique/Institut National des Sciences de l'Univers (CNRS/INSU). Cameras such as this are key components of the next generation of adaptive optics instruments of Europe's ground-based astronomy flagship facility, the ESO Very Large Telescope (VLT). ESO PR Photo 22a/09 The CCD220 detector ESO PR Photo 22b/09 The OCam camera ESO PR Video 22a/09 OCam images "The performance of this breakthrough camera is without an equivalent anywhere in the world. The camera will enable great leaps forward in many areas of the study of the Universe," says Norbert Hubin, head of the Adaptive Optics department at ESO. OCam will be part of the second-generation VLT instrument SPHERE. To be installed in 2011, SPHERE will take images of giant exoplanets orbiting nearby stars. A fast camera such as this is needed as an essential component for the modern adaptive optics instruments used on the largest ground-based telescopes. Telescopes on the ground suffer from the blurring effect induced by atmospheric turbulence. This turbulence causes the stars to twinkle in a way that delights poets, but frustrates astronomers, since it blurs the finest details of the images. Adaptive optics techniques overcome this major drawback, so that ground-based telescopes can produce images that are as sharp as if taken from space. Adaptive optics is based on real-time corrections computed from images obtained by a special camera working at very high speeds. Nowadays, this means many hundreds of times each second. The new generation instruments require these

Data from an applied research project on ageism among health professionals were used to examine nurses' attitudes toward aging and working with older adults. Nurses were compared with groups of other health professionals, and sources of variation within the nurses (e.g., employer, work setting, gerontology education) were examined. Nurses had less accurate knowledge of aging than other health professionals. Nurses expressed higher anxiety about aging and were more likely to believe working with older adults was associated with low esteem in the profession. Nurses were more likely to hold positive attitudes if they worked for a service provider rather than an employment agency, had gerontology education, and worked outside the residential care sector. Improving education in gerontology is an important strategy in improving the attitudes of the profession toward older adults and could help to address nursing shortages in this sector.

The volume of data generated by modern astronomical telescopes is extremely large and rapidly growing. However, current high-performance data processing architectures/frameworks are not well suited for astronomers because of their limitations and programming difficulties. In this paper, we therefore present OpenCluster, an open-source distributed computing framework to support rapidly developing high-performance processing pipelines of astronomical big data. We first detail the OpenCluster design principles and implementations and present the APIs facilitated by the framework. We then demonstrate a case in which OpenCluster is used to resolve complex data processing problems for developing a pipeline for the Mingantu Ultrawide Spectral Radioheliograph. Finally, we present our OpenCluster performance evaluation. Overall, OpenCluster provides not only high fault tolerance and simple programming interfaces, but also a flexible means of scaling up the number of interacting entities. OpenCluster thereby provides an easily integrated distributed computing framework for quickly developing a high-performance data processing system of astronomical telescopes and for significantly reducing software development expenses.

Preconception care may decrease adverse pregnancy outcomes associated with pre-existing diabetes mellitus. Aboriginal Australians are at high risk of type 2 diabetes mellitus (T2DM), with earlier onset. We explored practitioner views on preconception care delivery for women with T2DM in the Northern Territory, where 31% of births are to Aboriginal women. Mixed-methods study including cross-sectional survey of 156 health practitioners and 11 semi-structured interviews. Practitioners reported low attendance for preconception care however, 51% provided counselling on an opportunistic basis. Rural/remote practitioners were most likely to find counselling feasible. The majority (69%) utilised appropriate guidelines and addressed lifestyle modifications including smoking (81%), weight management (79%), and change medications appropriately such as ceasing ACE inhibitors (69%). Fewer (40%) prescribed the recommended dose of folate (5mg) or felt comfortable recommending delaying pregnancy to achieve optimal preconception glucose control (42%). Themes identified as barriers to care included the complexity of care setting and infrequent preconception consultations. There was a focus on motivation of women to make informed choices about conception, including birth spacing, timing and contraception. Preconception care enablers included cross-cultural communication, a multi-disciplinary care team and strong client-based relationships. Health practitioners are keen to provide preconception counselling and reported knowledge of evidence-based guidelines. Improvements are needed in recommending high dose folate and optimising glucose control. Cross-cultural communication and team-based care were reported as fundamental to successful preconception care in women with T2DM. Continued education and policy changes are required to support practitioners in opportunities to enhance pregnancy planning. Copyright © 2017 Elsevier B.V. All rights reserved.

Astronomy presents extraordinary opportunities for engaging young people in science from an early age. The National Optical Astronomy Observatory (NOAO), supported by the National Science Foundation, leverages the attraction of astronomy with a suite of formal and informal education programs that engage our scientists and education and public outreach professionals in effective, strategic programs that capitalize on NOAO's role as a leader in science and in the design of new astronomical facilities. The core of the science education group at NOAO in Tucson consists of a group of Ph.D.-level scientists with experience in educational program management, curriculum and instructional materials development, teacher/scientist partnerships, and teacher professional development. This core group of scientist/educators hybrids has a strong background in earth and space science education as well as experience in working with and teaching about the technology that has enabled new astronomical discoveries. NOAO has a vigorous public affairs/media program and a history of effectively working locally, regionally, and nationally with the media, schools, science centers, and, planetaria. In particular, NOAO has created successful programs exploring how research data and tools can be used most effectively in the classroom. For example, the Teacher Leaders in Research Based Science Education explores how teachers can most effectively integrate astronomical research on novae, active galactic nuclei, and the Sun into classroom-based investigations. With immersive summer workshops at Kitt Peak National Observatory and the National Solar Observatory at Sacramento Peak, teachers learn research and instrumentation skills and how to encourage and maintain research activities in their classrooms. Some of the new facilities proposed in the recent decadal plan, Astronomy and Astrophysics in the New Millennium (National Academy Press), can provide extended opportunities for incorporating

To examine the relative contribution of providers' professional affiliation (medical vs. non-medical), involvement in research, and training needs for associations with endorsement of the following evidence-based practices (EBPs): (1) pharmacological - buprenorphine treatment and (2) psychosocial - Cognitive Behavioural Therapy (CBT). Secondary analysis from a 2008 survey of a national sample (n = 571) of substance abuse treatment providers (medical, social workers, psychologists and counsellors) affiliated with the United States National Institute on Drug Abuse's National Drug Abuse Treatment Clinical Trials Network. Multivariate linear regression models to analyze cross-sectional survey data. Results demonstrated that medical providers and providers with previous research involvement more strongly endorsed the effectiveness of buprenorphine over CBT. Compared to medical providers, psychosocial providers more strongly endorsed CBT. There was a positive association between needing training in rapport with patients and endorsement of buprenorphine and a negative association with CBT. There was a positive association between needing training in behavioural management and needs assessment and endorsement of CBT. Results underscore the importance of providers' involvement in research and the need for training medical and non-medical providers in practice areas that can purposely enhance their use of pharmacological and psychosocial EBPs.

State scope of practice (SoP) laws impose significant restrictions on the services that a nurse practitioner (NP) may provide in some states, yet evidence about SoP limitations on the quality of primary care is very limited. This study uses six different classifications of state regulations and bivariate and multivariate analyses to compare beneficiaries attributed to primary care nurse practitioners and primary care physicians in 2013 testing two hypotheses: (1) chronic disease management, cancer screening, preventable hospitalizations, and adverse outcomes of care provided by primary care nurse practitioners are better in reduced and restricted practice states compared to states without restrictions and (2) by decreasing access to care, SoP restrictions negatively affect the quality of primary care. Results show a lack of consistent association between quality of primary care provided by NPs and state SoP restrictions. State regulations restricting NP SoP do not improve the quality of care.

The quality of modern astronomical data, the power of modern computers and the agility of current image processing software enable the creation of high-quality images in a purely digital form that rival the quality of traditional photographic astronomical images. The combination of these technological advancements has created a new ability to make color astronomical images. And in many ways, it has led to a new philosophy towards how to create them. We present a practical guide to generate astronomical images from research data by using powerful image processing programs. These programs use a layering metaphor that allows an unlimited number of astronomical datasets to be combined in any desired color scheme, creating an immense parameter space to be explored using an iterative approach. Several examples of image creation are presented. We also present a philosophy on how to use color and composition to create images that simultaneously highlight the scientific detail within an image and are aesthetically appealing. We advocate an approach that uses visual grammar, defined as the elements which affect the interpretation of an image, to maximize the richness and detail in an image while maintaining scientific accuracy. By properly using visual grammar, one can imply qualities that a two-dimensional image intrinsically cannot show, such as depth, motion and energy. In addition, composition can be used to engage the viewer and keep him or her interested for a longer period of time. The effective use of these techniques can result in a striking image that will effectively convey the science within the image, to scientists and to the public.

Ross River virus (RRV) causes the most common human arbovirus disease in Australia. Although the disease is nonfatal, the associated arthritis and postinfection fatigue can be debilitating for many months, impacting on workforce participation. We sought to create an early-warning system to notify of approaching RRV disease outbreak conditions for major townships in the Northern Territory. By applying a logistic regression model to meteorologic factors, including rainfall, a postestimation analysis of sensitivity and specificity can create rainfall cut-points. These rainfall cut-points indicate the rainfall level above which previous epidemic conditions have occurred. Furthermore, rainfall cut-points indirectly adjust for vertebrate host data from the agile wallaby (Macropus agilis) as the life cycle of the agile wallaby is intricately meshed with the wet season. Once generated, cut-points can thus be used prospectively to allow timely implementation of larval survey and control measures and public health warnings to preemptively reduce RRV disease incidence. Cut-points are location specific and have the capacity to replace previously used models, which require data management and input, and rarely provide timely notification for vector control requirements and public health warnings. These methods can be adapted for use elsewhere.

A Practical Guide to Lightcurve Photometry and Analysis provides, for those with access to even a modest telescope and CCD camera, all the information needed to take part in the scientific study of asteroids and variable stars. Using commercially available equipment, amateur astronomers can determine the rotation rate, size, and shape of asteroids. Similarly, it is possible to discover the size, temperature, and orbits of stars in binary systems by using this powerful technique. A Practical Guide to Lightcurve Photometry and Analysis contains all the material needed for readers to understand the theory, and avoid the practical pitfalls of lightcurve photometry. Detailed examples are given for obtaining data, and of course for the exciting and rewarding task of analyzing the data to determine the physical properties of the object. Any college student or amateur astronomer who wants to go beyond mere imaging with a CCD camera and enter the challenging world of "real science" via the lightcurves of asteroids and...
Sarmizegetusa Regia, the former capital city of the Dacians' kingdom, is situated in the Şureanu (Orăştie) Mountains in the Southern Carpathians, Romania. This chapter reviews, from the astronomical point of view, two of the monuments located on its Sacred Terrace - the altar known as the "Andesite Sun" and the Central Apse of the Great Round Sanctuary - as well as sanctuaries at the nearby site of Costeşti. Astronomical analyses taking into consideration (a) the astronomical-geometrical methods of the time (the analemma of a sundial after Vitruvius and the stereographical projection in the sense of Hipparchus), (b) astronomical instruments of the time (the gnomon, the sundial and the astrolabe), and (c) other instruments known to the Dacians (the compass), have concluded that these monuments may have enabled the Dacians to carry out a number of astronomical observations. This would confirm several reports by contemporary historians regarding the Dacians' knowledge of astronomy.

In this data-rich era of astronomy, there is a growing reliance on automated techniques to discover new knowledge. The role of the astronomer may change from being a discoverer to being a confirmer. But what do astronomers actually look at when they distinguish between “sources” and “noise?” What are the differences between novice and expert astronomers when it comes to visual-based discovery? Can we identify elite talent or coach astronomers to maximize their potential for discovery? By looking to the field of sports performance analysis, we consider an established, domain-wide approach, where the expertise of the viewer (i.e., a member of the coaching team) plays a crucial role in identifying and determining the subtle features of gameplay that provide a winning advantage. As an initial case study, we investigate whether the SportsCode performance analysis software can be used to understand and document how an experienced Hi astronomer makes discoveries in spectral data cubes. We find that the process of timeline-based coding can be applied to spectral cube data by mapping spectral channels to frames within a movie. SportsCode provides a range of easy to use methods for annotation, including feature-based codes and labels, text annotations associated with codes, and image-based drawing. The outputs, including instance movies that are uniquely associated with coded events, provide the basis for a training program or team-based analysis that could be used in unison with discipline specific analysis software. In this coordinated approach to visualization and analysis, SportsCode can act as a visual notebook, recording the insight and decisions in partnership with established analysis methods. Alternatively, in situ annotation and coding of features would be a valuable addition to existing and future visualization and analysis packages.
Full Text Available Background: Acute pesticide poisoning (APP is commonly underdiagnosed in Tanzania. Studies in developing countries suggest that a lack of diagnostic skills among health care providers (HCPs undermines surveillance for APP. This study aimed at characterizing experience and skills of Tanzanian HCPs regarding APP diagnosis and management. Methodology: The population included HCPs responsible for managing APP in Kilimanjaro and Arusha regions (n = 91. The resulting sample included 66 respondents (response rate: 73%. The data were collected in 2005 using a standardized questionnaire. Results: Half of all respondents (50% reported handling at least 1 APP case with 15% reporting handling more than 5 cases in the past. Reported experience of handling an APP case was marginally higher in respondents who reported ⩾4 years of work experience in the health sector compared with those with <4 years of work experience (odds ratio = 1.32; 95% confidence interval = 0.9-1.5. Most of the respondents had high knowledge of exposure routes, reporting awareness of oral (98.5%, inhalational (93.9%, and dermal (77% routes. The study revealed low awareness of pesticide classification by chemical groups (29% or World Health Organization hazard (0% and weak knowledge on pesticide label instructions (55%. Organophosphates accounted for 35% of the pesticide products reported by respondents as being responsible for poisoning. Some treatment options were incorrectly reported as first aid options, and some reported first aid options were wrong or inappropriate. Conclusions: The study revealed that HCPs in northern Tanzania lack adequate skills to diagnose and manage APP. For effective surveillance of APP, there is a need to include training on hazards, classification, diagnosis, and health effects in the training programmes for all HCPs in Tanzania.

As telescopes, detectors, and computers grow ever more powerful, the volume of data at the disposal of astronomers and astrophysicists will enter the petabyte domain, providing accurate measurements for billions of celestial objects. This book provides a comprehensive and accessible introduction to the cutting-edge statistical methods needed to efficiently analyze complex data sets from astronomical surveys such as the Panoramic Survey Telescope and Rapid Response System, the Dark Energy Survey, and the upcoming Large Synoptic Survey Telescope. It serves as a practical handbook for graduate s
An international team of astronomers has used the National Science Foundation's Very Long Baseline Array (VLBA) radio telescope and NASA's Hubble Space Telescope (HST) to discover the first gravitational lens in which the single image of a very distant galaxy has been split into six different images. The unique configuration is produced by the gravitational effect of three galaxies along the line of sight between the more-distant galaxy and Earth. Optical and Radio Images of Gravitational Lens "This is the first gravitational lens with more than four images of the background object that is produced by a small group of galaxies rather than a large cluster of galaxies," said David Rusin, who just received his Ph.D. from the University of Pennsylvania. "Such systems are expected to be extremely rare, so this discovery is an important stepping stone. Because this is an intermediate case between gravitational lenses produced by single galaxies and lenses produced by large clusters of galaxies, it will give us insights we can't get from other types of lenses," Rusin added. The gravitational lens, called CLASS B1359+154, consists of a galaxy more than 11 billion light-years away in the constellation Bootes, with a trio of galaxies more than 7 billion light-years away along the same line of sight. The more-distant galaxy shows signs that it contains a massive black hole at its core and also has regions in which new stars are forming. The gravitational effect of the intervening galaxies has caused the light and radio waves from the single, more-distant galaxy to be "bent" to form six images as seen from Earth. Four of these images appear outside the triangle formed by the three intermediate galaxies and two appear inside that triangle. "This lens system is a very interesting case to study because it is more complicated than lenses produced by single galaxies, and yet simpler than lenses produced by clusters of numerous galaxies," said Chris Kochanek of the Harvard
Full Text Available Abstract Background Out-of-pocket payments make up about 80% of medical care spending at hospitals in Laos, thereby putting poor households at risk of catastrophic health expenditure. Social security schemes in the form of community-based health insurance and health equity funds have been introduced in some parts of the country. Drug and Therapeutics Committees (DTCs have been established to ensure rational use of drugs and improve quality of care. The objective was to assess the appropriateness and expenditure for treatment for poor patients by health care providers at hospitals in three selected provinces of Laos and to explore associated factors. Methods Cross-sectional study using four tracer conditions. Structured interviews with 828 in-patients at twelve provincial and district hospitals on the subject of insurance protection, income and expenditures for treatment, including informal payment. Evaluation of each patient's medical record for appropriateness of drug use using a checklist of treatment guidelines (maximum score = 10. Results No significant difference in appropriateness of care for patients at different income levels, but higher expenditures for patients with the highest income level. The score for appropriate drug use in insured patients was significantly higher than uninsured patients (5.9 vs. 4.9, and the length of stay in days significantly shorter (2.7 vs. 3.7. Insured patients paid significantly less than uninsured patients, both for medicines (USD 14.8 vs. 43.9 and diagnostic tests (USD 5.9 vs. 9.2. On the contrary the score for appropriateness of drug use in patients making informal payments was significantly lower than patients not making informal payments (3.5 vs. 5.1, and the length of stay significantly longer (6.8 vs. 3.2, while expenditures were significantly higher both for medicines (USD 124.5 vs. 28.8 and diagnostic tests (USD 14.1 vs. 7.7. Conclusions The lower expenditure for insured patients can help reduce

We describe the application of machine classification techniques to the development of an automated tool for the reduction of a large scientific data set. The 2nd Palomer Observatory Sky Survey is nearly completed. This survey provides comprehensive coverage of the northern celestial hemisphere in the form of photographic plates. The plates are being transformed into digitized images whose quality will probably not be surpassed in the next ten to twenty years. The images are expected to contain on the order of 10(exp 7) galaxies and 10(exp 8) stars. Astronomers wish to determine which of these sky objects belong to various classes of galaxies and stars. The size of this data set precludes manual analysis. Our approach is to develop a software system which integrates the functions of independently developed techniques for image processing and data classification. Digitized sky images are passed through image processing routines to identify sky objects and to extract a set of features for each object. These routines are used to help select a useful set of attributes for classifying sky objects. Then GID3* and O-BTree, two inductive learning techniques, learn classification decision trees from examples. These classifiers will be used to process the rest of the data. This paper gives an overview of the machine learning techniques used, describes the details of our specific application, and reports the initial encouraging results. The results indicate that our approach is well-suited to the problem. The primary benefits of the approach are increased data reduction throughput and consistency of classification. The classification rules which are the product of the inductive learning techniques will form an object, examinable basis for classifying sky objects. A final, not to be underestimated benefit is that astronomers will be freed from the tedium of an intensely visual task to pursue more challenging analysis and interpretation problems based on automatically cataloged
In the North-East part of Macedonia, near to the peak Tatikjev Kamen, an archaeological site with vast quantity of artifacts, dated in the Bronze Age, was discovered in 2001. For the first time in Republic of Macedonia (FYROM), comprehensive archaeo-astronomical analysis of this site, providing extraordinary important results, was performed in 2002. The site contains a lot of materials typical for a megalithic observatory, 3800 years old. Three stone markers, pointing out the places of the sunrise on the days of the summer and winter solstice, as well as the vernal and autumn equinoxes, were found there. Four stone markers, indicating the places of the full Moon rise above the horizon, are recognized too. They are used in the days when the Moon has maximum or minimum declination - two of them in the summer and two of them - in the winter. There are also two other stone markers used for measuring the length of the lunar month in winter - when it has 29 days, and in summer - when it has 30 days. These markers give clear evidences that the ancient Balkan inhabitants used the observatory not only to monitor the movement of the Moon, but also to develop the lunar calendar with 19-year cycle. The archaeo-astronomical analysis presents also an evidence for the existence of one very characteristic stone marker, used for pointing out the sunrise position in a very important ritual day. This is the day when special ceremonies related to the end of the harvest, as well as to the ritual unification of the community leader with the God Sun, were performed.

Full Text Available Abstract Background Evidence-based obstetric care is widely promoted in developing countries, but the success of implementation is not known. Using selected childbirth care procedures in four hospitals in Shanghai, we compared practice against evidence-based information, and explored user and provider views about each procedure. Methods Observational study. Using the Cochrane Library, we identified six procedures that should be avoided as routine and two that should be encouraged. Procedure rate determined by exit interviews with women, verified using hospital notes. Views of women and providers explored with in depth interviews. The study sites were three hospitals in Shanghai and one in neighbouring province of Jiangsu. 150 women at each centre for procedure rate, and 48 in-depth interviews with women and providers. Results Vaginal births were 50% (303/599 of the total. Of the six practices where evidence suggests they should be avoided as routine, three were performed with rates above 70%: pubic shaving (3 hospitals, rectal examination (3 hospitals, and episiotomy (3 hospitals. Most women delivered lying down, pain relief was rarely given, and only in the urban district hospital did women routinely have a companion. Most women wanted support or companionship during labour and to be given pain relief; but current practice is insufficient to meet women's needs. Conclusion Obstetric practice is not following best available evidence in the hospitals studied. There is a need to adjust hospital policy to support the use of interventions proven to be of benefit to women during childbirth, and develop approaches that ensure clinical practice changes.
Full Text Available Children with autism spectrum disorders (ASD have several risk factors for low bone mineral density. The gluten-free, casein-free (GFCF diet is a complementary therapy sometimes used in ASD that raises concerns for the adequacy of calcium and vitamin D intake. This study evaluated the prescribing practices of calcium and vitamin D supplements and the practice of checking 25-hydroxy vitamin D (25(OHD levels by providers in 100 children with ASD, 50 of whom were on the GFCF diet. Fifty-two percent and 46% of children on the GFCF diet were on some form of vitamin D and calcium supplements, respectively, compared to 18% and 14% of those not on this diet. Twenty-four percent of children in the GFCF group had a documented 25(OHD level compared to none in the non-GFCF group. The data highlight a gap in calcium and vitamin D supplement prescribing practices among providers caring for children with ASD as well as a gap in the practice of checking 25(OHD levels.
Astronomers using the National Science Foundation's Robert C. Byrd Green Bank Telescope have discovered the fastest-spinning neutron star ever found, a 20-mile-diameter superdense pulsar whirling faster than the blades of a kitchen blender. Their work yields important new information about the nature of one of the most exotic forms of matter known in the Universe. Pulsar Graphic Pulsars Are Spinning Neutron Stars CREDIT: Bill Saxton, NRAO/AUI/NSF (Click on image for larger version) "We believe that the matter in neutron stars is denser than an atomic nucleus, but it is unclear by how much. Our observations of such a rapidly rotating star set a hard upper limit on its size, and hence on how dense the star can be.," said Jason Hessels, a graduate student at McGill University in Montreal. Hessels and his colleagues presented their findings to the American Astronomical Society's meeting in Washington, DC. Pulsars are spinning neutron stars that sling "lighthouse beams" of radio waves or light around as they spin. A neutron star is what is left after a massive star explodes at the end of its "normal" life. With no nuclear fuel left to produce energy to offset the stellar remnant's weight, its material is compressed to extreme densities. The pressure squeezes together most of its protons and electrons to form neutrons; hence, the name "neutron star." "Neutron stars are incredible laboratories for learning about the physics of the fundamental particles of nature, and this pulsar has given us an important new limit," explained Scott Ransom, an astronomer at the National Radio Astronomy Observatory and one of Hessels' collaborators on this work. The scientists discovered the pulsar, named PSR J1748-2446ad, in a globular cluster of stars called Terzan 5, located some 28,000 light-years from Earth in the constellation Sagittarius. The newly-discovered pulsar is spinning 716 times per second, or at 716 Hertz (Hz), readily beating the previous record of 642 Hz from a pulsar
Spectroscopy is one of the most powerful tools to study the physical properties and chemical composition of very diverse astrophysical environments. In principle, each nuclide has a unique set of spectral features; thus, establishing the presence of a specific material at astronomical distances requires no more than finding a laboratory spectrum of the right material that perfectly matches the astronomical observations. Once the presence of a substance is established, a careful analysis of the observational characteristics (wavelengths or frequencies, intensities, and line profiles) allows one to determine many physical parameters of the environment in which the substance resides, such as temperature, density, velocity, and so on. Because of this great diagnostic potential, ground-based and space-borne astronomical observatories often include instruments to carry out spectroscopic analyses of various celestial objects and events. Of particular interest is molecular spectroscopy at infrared wavelengths. From the spectroscopic point of view, molecules differ from atoms in their ability to vibrate and rotate, and quantum physics inevitably causes those motions to be quantized. The energies required to excite vibrations or rotations are such that vibrational transitions generally occur at infrared wavelengths, whereas pure rotational transitions typically occur at sub-mm wavelengths. Molecular vibration and rotation are coupled though, and thus at infrared wavelengths, one commonly observes a multitude of ro-vibrational transitions (see Figure 13.1). At lower spectral resolution, all transitions blend into one broad ro-vibrational molecular band. The isotope. Molecular spectroscopy thus allows us to see a difference of one neutron in an atomic nucleus that is located at astronomical distances! Since the detection of the first interstellar molecules (the CH  and CN  radicals), more than 150 species have been detected in space, ranging in size from diatomic
improve our understanding of the life-cycle of stars.' The Chandra X-ray data also reveal the signatures of neon, an expected by-product of helium fusion. However, a big surprise was the presence of magnesium in similar quantities. This result may provide a key to the unique composition of H1504+65 and validate theoretical predictions that, if massive enough, some stars can extend their lives by tapping yet another energy source: the fusion of carbon into magnesium. However, as magnesium can also be produced by helium fusion, proof of the theory is not yet ironclad. The final link in the puzzle would be the detection of sodium, which will require data from yet another observatory: the Hubble Space Telescope. The team has already been awarded time on the Hubble Space Telescope to search for sodium in H1504+65 next year, and will, hopefully, discover the final answer as to the origin of this unique star. This work will be published in July in the 'Astronomy & Astrophysics' journal. The Chandra X-ray Observatory and the Far Ultraviolet Spectroscopic Explorer (FUSE) were both launched into orbit by NASA in 1999. Their instruments make use of a technique called spectroscopy, which spreads the light obtained from astronomical objects into its constituent X-ray and ultraviolet 'colours', in the same way visible light is dispersed into a rainbow naturally, by water droplets in the atmosphere, or artificially, by a prism. When studied in fine detail each spectrum is a unique 'fingerprint' which tells us what elements are present and reveals the physical conditions in the object being studied.

Since 2007 I have been a Team Leader for the Tzec Maun Foundation, a non-profit foundation dedicated to providing free, research grade, Internet telescopes to students, teachers and researchers around the world. The name Tzec Maun (pronounced “Teh-Zeck-Moan”) comes from Mayan culture. Tzec Maun was the jovial messenger, laughed at adversity. Based on the challenges students, researchers and professional astronomers face with finances, equipment, and telescope access, the jovial mascot seems to fit. Hundreds of hours performing astronomical outreach as a NASA/JPL Solar System Ambassador and Astronomical League Master of outreach taught me that the best way to inspirationally teach astronomy and space science (and most subjects) is actually being at the eyepiece. I’m NOT a fan of the traditional planetarium experience as a teaching tool because it inhibits inspiration and the learning experience to a 2-D mat on a faux horizon with artificial representations. Once, a student at my dark sky observatory excitedly commented that the night sky was like a 3-D planetarium. I have hosted several classes at my own personal dark sky observatory, but this resource is impractical for all but a few lucky students. Experience has taught me that the next best thing to being at the eyepiece is to control a remote telescope via the Internet. Tzec Maun’s arsenal of telescopes is all research capable, linked to the Internet and positioned for round-the-clock dark skies. The final conditions described above, mean that I can enter an 8:30am science class, log onto the Tzec Maun telescope Portal and turn over control of an Australian system (where it is night) to a student or teacher. Working as a group, the class can either begin their investigations. My Tzec Maun science team (TARP) is engaged in searching for potentially hazardous asteroids (PHAs). PHA work excites student and teacher alike. Teaching from telescopes can unleash powerful attention-getting tools that enable

The primary aim of this study was to assess the influence of provision of information on lay citizens' opinions regarding 2 common management practices, zero-grazing and cow-calf separation. To aid in the interpretation of the findings, our secondary aim was to explore the awareness and opinions of Brazilian citizens about these practices. We surveyed a convenience sample of Brazilian citizens (192 men and 208 women), recruited in a public place, with the majority stating that they were largely unfamiliar with animal production and lived in urban environments. Participants were presented short scenarios with information on the primary production factors and welfare concerns for and against zero-grazing (n = 200) or cow-calf separation (n = 200). Participants were then asked to state their position (reject, indifferent, or support), and to provide the reason(s) justifying their position. Immediately following, participants were provided a short statement describing either zero-grazing or cow-calf separation, depending on what question they responded to in the first part. Two closed questions (Q) followed each of these statements: (Q1) "Are you aware of this practice?" with choices yes, somewhat, or no, and (Q2) "What is your position regarding this practice?" with choices reject, indifferent, or support. Only 31 and 33% of the respondents were aware of zero-grazing and cow-calf separation, respectively. Previous awareness of existence of practice did not influence levels of support. Provision of information resulted in more people rejecting the practices of zero-grazing and cow-calf separation. Participants' main justifications to reject zero-grazing and cow-calf separation focused on perceived negative effects of practices on farm animal welfare and product quality, and loss of naturalness. Survey participants, Brazilians living in urban environments, with little or no association with dairy production, were generally unaware that many cows do not have access to

The recent introduction of cell-free DNA-based non-invasive prenatal screening (cfDNA screening) into clinical practice was expected to revolutionize prenatal testing. cfDNA screening for fetal aneuploidy has demonstrated higher test sensitivity and specificity for some conditions than conventional serum screening and can be conducted early in the pregnancy. However, it is not clear whether and how clinical practices are assimilating this new type of testing into their informed consent and counselling processes. Since the introduction of cfDNA screening into practice in 2011, the uptake and scope have increased dramatically. Prenatal care providers are under pressure to stay up to date with rapidly changing cfDNA screening panels, manage increasing patient demands, and keep up with changing test costs, all while attempting to use the technology responsibly and ethically. While clinical literature on cfDNA screening has shown benefits for specific patient populations, it has also identified significant misunderstandings among providers and patients alike about the power of the technology. The unique features of cfDNA screening, in comparison to established prenatal testing technologies, have implications for informed decision-making and genetic counselling that must be addressed to ensure ethical practice. This study explored the experiences of prenatal care providers at the forefront of non-invasive genetic screening in the United States to understand how this testing changes the practice of prenatal medicine. We aimed to learn how the experience of providing and offering this testing differs from established prenatal testing methodologies. These differences may necessitate changes to patient education and consent procedures to maintain ethical practice. We used the online American Congress of Obstetricians and Gynecologists Physician Directory to identify a systematic sample of five prenatal care providers in each U.S. state and the District of Columbia.

Our current research focuses on the trajectory of scientists working with large-scale databases in astronomy, following them as they strategically build their careers, digital infrastructures, and make their epistemological commitments. We look specifically at how gender, ethnicity, nationality intersect in the process of subject formation in astronomy, as well as in the process of enrolling partners for the construction of instruments, design and implementation of large-scale databases. Work once figured as merely technical support, such assembling data catalogs, or as graphic design, generating pleasing images for public support, has been repositioned at the core of the field. Some have argued that such databases enable a new kind of scientific inquiry based on data exploration, such as the "fourth paradigm" or "data-driven" science. Our preliminary findings based on oral history interviews and ethnography provide insights into meshworks of women, African-American, "Hispanic," Asian-American and foreign-born astronomers. Our preliminary data suggest African-American men are more successful in sustaining astronomy careers than Chicano and Asian-American men. A distinctive theme in our data is the glocal character of meshworks available to and created by foreign-born women astronomers working at US facilities. Other data show that the proportion of Asian to Asian American and foreign-born Latina/o to Chicana/o astronomers is approximately equal. Futhermore, Asians and Latinas/os are represented in significantly greater numbers than Asian Americans and Chicanas/os. Among professional astronomers in the US, each ethnic minority group is numbered on the order of tens, not hundreds. Project support is provided by the NSF EAGER program to University of California, Los Angeles under award 0956589.

Medical providers' ability to form strong therapeutic alliances with patients is an essential clinical skill that is associated with a higher quality of care and improved provider well-being. However, comparatively few medical providers exhibit adequate relational skills, which serve to convey respect, communicate caring, and build trust between the medical provider and the patient. A growing number of medical training programs and continuing medical education programs have begun to incorporate relational skills training, but the results have been highly variable in terms of training methods and effect. To support administrators who are considering the implementation (or improvement) of relational skills training in their organization, we provide a set of best practices for relational skills training, in the basis of a review of the literature and on our experience as clinical educators, and show the application of these best practices through a case study. We conclude with a discussion of challenges for implementing a high-quality relational skills training program, policy-level solutions for these challenges, and recommendations for future research.

The recognition of astronomically forced (Milankovitch) climate cycles in geological archives marked a major advance in Earth science, revealing a heartbeat within the climate system of general importance and key utility. Power spectral analysis is the primary tool used to facilitate identification of astronomical cycles in stratigraphic data, but commonly employed methods for testing the statistical significance of relatively high narrow-band variance of potential astronomical origin in spectra have been criticized for inadequately balancing the respective probabilities of type I (false positive) and type II (false negative) errors. This has led to suggestions that the importance of astronomical forcing in Earth history is overstated. It can be readily demonstrated, however, that the imperfect nature of the stratigraphic record and the quasiperiodicity of astronomical cycles sets an upper limit on the attainable significance of astronomical signals. Optimized significance testing is that which minimizes the combined probability of type I and type II errors. Numerical simulations of stratigraphically preserved astronomical signals suggest that optimum significance levels at which to reject a null hypothesis of no astronomical forcing are between 0.01 and 0.001 (i.e., 99-99.9% confidence level). This is lower than commonly employed in the literature (90-99% confidence levels). Nevertheless, in consonance with the emergent view from other scientific disciplines, fixed-value null hypothesis significance testing of power spectra is implicitly ill suited to demonstrating astronomical forcing, and the use of spectral analysis remains a difficult and subjective endeavor in the absence of additional supporting evidence.
Full Text Available Previous decade has seen an achievement of large interferometric projects including 8-10m telescopes and 100m class baselines. Modern computer and control technology has enabled the interferometric combination of light from separate telescopes also in the visible and infrared regimes. Imaging with milli-arcsecond (mas resolution and astrometry with micro-arcsecond (µas precision have thus become reality. Here, I review the methods and instrumentation corresponding to the current state in the field of astronomical optical interferometry. First, this review summarizes the development from the pioneering works of Fizeau and Michelson. Next, the fundamental observables are described, followed by the discussion of the basic design principles of modern interferometers. The basic interferometric techniques such as speckle and aperture masking interferometry, aperture synthesis and nulling interferometry are discussed as well. Using the experience of past and existing facilities to illustrate important points, I consider particularly the new generation of large interferometers that has been recently commissioned (most notably, the CHARA, Keck, VLT and LBT Interferometers. Finally, I discuss the longer-term future of optical interferometry, including the possibilities of new large-scale ground-based projects and prospects for space interferometry.

The remarkable sensitivity of depleted silicon to ionizing radiation is a nuisance to astronomers. ''Cosmic rays'' degrade images because of struck pixels, leading to modified observing strategies and the development of algorithms to remove the unwanted artifacts. In the new-generation CCD's with thick sensitive regions, cosmic-ray muons make recognizable straight tracks and there is enhanced sensitivity to ambient gamma radiation via Compton-scattered electrons (''worms''). Beta emitters inside the dewar, for example high-potassium glasses such as BK7, also produce worm-like tracks. The cosmic-ray muon rate is irreducible and increases with altitude. The gamma rays are mostly by-products of the U and Th decay chains; these elements always appear as traces in concrete and other materials. The Compton recoil event rate can be reduced significantly by the choice of materials in the environment and dewar and by careful shielding. Telescope domes appear to be significantly cleaner than basement laboratories and Coude spectrograph rooms. Radiation sources inside the dewar can be eliminated by judicious choice of materials. Cosmogenic activation during high-altitude flights does not appear to be a problem. Our conclusions are supported by tests at the Lawrence Berkeley National Laboratory low-level counting facilities in Berkeley and at Oroville, California (180 m underground).

An unproductive 45-cm astronomical telescope, given by JICA (Japan) to Sri Lanka, raises general questions as to the reasons for unproductive pure science in developing countries. Before installation, site, maintenance, and scientific objectives were discussed. The facility was launched with a conference organised by the UN Office for Outer Space Affairs. Unfortunately, no research or significant education has resulted after four years. The annual operating cost is U.S. $5000 per year, including salary for a trainee, maintenance, and a modest promotional programme. Comparison with a similar installation in Auckland suggests lack of funding or technical competence do not explain the failure in Sri Lanka. The facility in New Zealand, on the roof of Auckland University's Physics Department, has a slightly smaller budget but has led to modest but useful research and teaching. Lack of financial backing and expertise are often blamed for weak science in developing countries, but examination shows most of these countries have adequately skilled people, and plenty of resources for religion and military. General lack of motivation for science appears to be the principal reason. This lack of interest and highly inefficient bureaucracies are common to scientifically unproductive countries. They mostly lack the cultural and philosophical base of the European Renaissance that motivate the pursuit of modern science, an activity that violates human preferences. There are excellent facilities (ESO, SAAO, Cerro Tololo, and GONG) in some of these same countries, when administered from the West.
