    AISES, None

    2013-09-25

    The American Indian Science and Engineering Society (AISES) has been funded under a U.S. Department of Energy (DOE) grant (Grant Award No. DE-SC0004058) to host an Intertribal Middle-School Science and Math Bowl (IMSSMB) comprised of teams made up of a majority of American Indian students from Bureau of Indian Education-funded schools and public schools. The intent of the AISES middle school science and math bowl is to increase participation of American Indian students at the DOE-sponsored National Science Bowl. Although national in its recruitment scope, the AISES Intertribal Science and Math Bowl is considered a “regional” science bowl, equivalent to the other 50 regional science bowls which are geographically limited to states. Most regional bowls do not have American Indian student teams competing, hence the AISES bowl is meant to encourage American Indian student teams to increase their science knowledge in order to participate at the national level. The AISES competition brings together teams from various American Indian communities across the nation. Each team is provided with funds for travel to and from the event, as well as for lodging and meals. In 2011 and 2012, there were 10 teams participating; in 2013, the number of teams participating doubled to 20. Each Science and Math Bowl team is comprised of four middle school — grades 6 through 8 — students, one alternate, and a teacher who serves as advisor and coach — although in at least two cases, the coach was not a teacher, but was the Indian Education Coordinator. Each team member must have at least a 3.0 GPA. Furthermore, the majority of students in each team must be comprised of American Indian, Alaska Native or Native Hawaiian students. Under the current DOE grant, AISES sponsored three annual middle school science bowl competitions over the years 2011, 2012 and 2013. The science and math bowls have been held in late March concurrently with the National American Indian Science and

  5. The National Ocean Sciences Bowl: An Effective Model for Engaging High School Students in Ocean Science

    Science.gov (United States)

    Holloway, A. E.

    2016-02-01

    The National Ocean Sciences Bowl (NOSB) is an informal high school education program that engages students in ocean and environmental science and exposes them to the breadth of ocean-related careers. The NOSB strives to train the next generation of interdisciplinary capable scientists and build a STEM-literate society that harnesses the power of ocean and climate science to address environmental, economic, and societal issues. Through the NOSB, students not only learn scientific principles, but also apply them to compelling real-world problems. The NOSB provides a richer STEM education and exposes students to ocean science topics they may not otherwise study through classroom curriculum. A longitudinal study that began in 2007 has shown that NOSB participants have an enhanced interest in ocean-related hobbies and environmental stewardship and an increasing number of these students have remained in the STEM pipeline and workforce.While the NOSB is primarily an academic competition, it has evolved since its creation in 1998 to include a variety of practical and professional development components. One of the program enhancements, the Scientific Expert Briefing (SEB), gives students the opportunity to apply what they have studied and think critically about current and ongoing ocean science challenges. The SEB helps students connect their knowledge of ocean science with current and proposed policy initiatives. Students gain significant research, writing, and presentation skills, while enhancing their ability for collaboration and consensus building, all vital workforce skills. Ultimately, the SEB teaches students how to communicate complex scientific research into digestible information for decision-makers and the general public.This poster will examine the impact of the NOSB and its role in strengthening the workforce pipeline through a combination of independent learning, competition, and opportunities for communication skills development.

  6. Public Understanding of Science in turbulent times III: Deficit to dialogue, champions to critics.

    2016-02-01

    As part of the 20th Anniversary of the Public Understanding of Science journal, the journal has been reflecting on how the field and journal have developed. This research note takes a closer look at some of the trends, considering the journal's 50 most cited papers and using IRaMuTeQ, an open-source computer text analysis technique. The research note presents data that show that the move within public engagement from deficit to dialogue has been followed by a further shift from championing dialogue to criticising its practice. This shift has taken place alongside a continued, but changing, interest in media coverage, surveys and models of public understanding. © The Author(s) 2014.

    2011-01-01

    We present the results of an experimental investigation of the acoustics and fluid dynamics of Tibetan singing bowls. Their acoustic behaviour is rationalized in terms of the related dynamics of standing bells and wine glasses. Striking or rubbing a fluid-filled bowl excites wall vibrations, and concomitant waves at the fluid surface. Acoustic excitation of the bowl's natural vibrational modes allows for a controlled study in which the evolution of the surface waves with increasing forcing amplitude is detailed. Particular attention is given to rationalizing the observed criteria for the onset of edge-induced Faraday waves and droplet generation via surface fracture. Our study indicates that drops may be levitated on the fluid surface, induced to bounce on or skip across the vibrating fluid surface. (invited article)

    2010-01-01

    10 November 1972: CERN’s Bent Stumpe places an order for 12 bowling balls for a total cost of 95 US dollars. Although not evident at first sight, he is buying the heart of some of the first tracking devices to be used in the SPS control room. Today, Bent Stumpe’s device would be called a desktop mouse…   The first order for 4 bowling balls later changed to 12 balls. The bowling balls became the heart of Bent Stumpe's mouse. Almost 40 years ago, the web, Wikipedia and Google did not exist and it was much more difficult to know whether other people in other parts of the world or even in the same laboratory were facing the same problems or developing the same tools. At that time, Bent Stumpe was an electronics engineer, newly recruited to work on developments for the SPS Central Control room. One of the things his supervisor asked him to build as soon as possible was a device to control a pointer on a screen, also called a tracker ball. The heart of the device was the...

    2016-01-01

    Although ethics is an essential component of undergraduate medical education, research suggests that current medical ethics curricula face considerable challenges in improving students' ethical reasoning. This article discusses these challenges and introduces a promising new mode of graduate and professional ethics instruction for overcoming them. We begin by describing common ethics curricula, focusing in particular on established problems with current approaches. Next, we describe a novel method of ethics education and assessment for medical students that we have devised: the Medical Ethics Bowl (MEB). Finally, we suggest the pedagogical advantages of the MEB when compared to other ethics curricula.

  19. Giuseppe Sergi, "champion" of Darwinism?

    Science.gov (United States)

    Volpone, Alessandro

    2011-01-01

    The Italian anthropologist, psychologist and evolutionist Giuseppe Sergi (1841-1936) may be regarded in some respects today as an "atypical" Darwinist, but, almost paradoxically, he was considered a "champion" of Darwinism by colleagues and commentators of his own time. Probably, two aspects of his work are responsible for this apparent anomaly: his faith in the so-called soft inheritance and his claims regarding a theory concerning the polyphyletic origin of human races. The soft inheritance theory, however, was needed by Sergi to support ideas regarding the complexity of inheritance in man, a fact that, in his opinion, could not completely be put down to mechanical laws, and polygeny was useful when trying to rectify the problem concerning the incompleteness of the fossil record. In both cases, it is possible to show that he was involved in supporting Darwinian theory during the most severe crisis of its consensus in Italy and at International level, between the end of the 19th century and the beginning of the 20th. Finally, the apparent unorthodox features which can be found in Sergi's ideas appear to be, in Kuhnian terms, ad hoc hypotheses put forward by Sergi himself in order to support the paradigm.

  4. Vinča bowls with protoma

    Directory of Open Access Journals (Sweden)

    Spasić Miloš P.

    2014-01-01

    Full Text Available Bowls with protoma represent one of several tens of types of Vinča vessels made of baked clay which have been published as finds excavated at Vinča sites for more than a century. We are dealing here with bowls of a markedly conical profile, with angled and slightly rounded walls and with a flat or slightly annular bottom. In most cases these bowls are not decorated, with the exception of the rare finds decorated by fluting, engraving and polishing. Their most significant peculiarity is the presence of four or eight protoma on the rim, facing the inside of the vessel. Taking into consideration all stylistic-typological characteristics, it is possible to divide them into two coherent categories of finds. The first consists of bowls with four oppositely placed protoma. Within this group it is possible to single out two subtypes, bowls with all four as anthropomorphic (Pl. I/6, 7; Pl. III/34 or all four as zoomorphic representations (Pl. I/5, 8, 9; Pl. III/33, 36. Bowls with eight protoma have actually got four pairs of oppositely placed representations. It was possible to discern two subtypes based on the objects that were completely preserved. The first subtype includes a bowl from the so-called Vinča ritual set, with two pairs of zoomorphic and two pairs of anthropomorphic protoma, both oppositely placed (Pl. I/3. The second subtype includes a bowl from house 1/2010 from Stubline with four identical, paired, totally stylised and schematised representations, whose identification is impossible (Fig. 1; Pl. I/1. Taking into consideration the metric and technological data, the thesis that seems most possible is that the bowls with protoma served for the consumption of or the storing/displaying of the content during some quite specific activities. Bowls with protoma appear in almost all regions of the central Balkans populated by Vinča culture communities and we do not note them in the areas of the neighbouring Late Neolithic communities.

  5. A special danger in bowling and skittle – bowling ball induced injuries of the distal fingers

    Directory of Open Access Journals (Sweden)

    Könneker, Sören

    2017-09-01

    Full Text Available Purpose: Injuries to the hand and fingers have been reported related to the popular sports of bowling and skittle. Both sports differ regarding size, shape, weight of the ball and technique. The focus of this study is to address whether bowling or skittle players are more prone to injuries. Methods: We assessed hand injuries related to bowling or skittle in a retrospective analysis of patients treated in our department between 2006 and 2016. We also investigated differences between both sports with regards to patient demographics, type and location of lesion, and treatment.Results: A total of 13 patients were identified with minors comprising a total of number of six patients. Six from the overall cohort developed injuries related to bowling, and seven sustained injuries related to skittle. In all cases, the pattern of injury revealed a contusion between two balls during retrieval. The distal phalanx was affected in all patients, and the middle phalanx in one. Out of the 13 patients, one patient presented with lesions on the 3 finger, ten patients on the 4 finger and two patients on the 5 finger. In cases of bone injury (n=10, patients received surgical treatment via K-wire-fixation (n=2, suture-cerclage (n=1, resection of little distal fragments (n=1 or splinting only (n=6. There were no significant differences between patients with bowling or skittle injuries with regard to frequency, type and location of the lesions.Conclusion: Bowling and skittle are comparable with their inherent risk of distal finger trauma. Almost all cases required surgical intervention. As most injuries occurred during retrieval of the ball from the rack, efforts should be put on prevention at this point. In both sports the majority of patients were minor, so age restriction should be evaluated.Level of evidence: Therapeutic study, level IV

  7. Challenges Facing Healthwatch, a New Consumer Champion in England.

    Science.gov (United States)

    Carter, Pam; Martin, Graham

    2016-01-21

    This article engages with debates about the conceptualisation and practical challenges of patient and public involvement (PPI) in health and social care services. Policy in this area in England has shifted numerous times but increasingly a consumerist discourse seems to override more democratic ideas concerning the relationship between citizens and public services. Recent policy change in England has seen the creation of new consumer champion bodies in the form of local Healthwatch. The article describes these new organisational structures for PPI and shows how those who seek to influence planning and delivery of services or comment or complain about aspects of their care face considerable complexity. This is due, in part, to the ambiguous remit set out for newly instigated Healthwatch organisations by government. Drawing on governance theory, we show that it can also be understood as a function of an increasingly polycentric governance arena. Challenges that flow from this include problems of specifying jurisdictional responsibility, accountability, and legitimacy. We review Healthwatch progress to date, then we set out four challenges facing local Healthwatch organisations before discussing the implications of these for patients and the public. The first challenge relates to non-coterminous boundaries and jurisdictional integrity. Secondly, establishing the unique features of Healthwatch is problematic in the crowded PPI arena. The third challenge arises from limited resources as well as the fact that resources flow to Healthwatch from the local authorities that Healthwatch are expected to hold to account. The fourth challenge we identify is how local Healthwatch organisations negotiate the complexity of being a partner to statutory and other organisations, while at the same time being expected to champion local people's views. © 2016 by Kerman University of Medical Sciences.

    2016-01-01

    Full Text Available The real-world experiences of young athletes follow a non-linear and dynamic trajectory and there is growing recognition that facing and overcoming a degree of challenge is desirable for aspiring elites and as such, should be recognized and employed. However, there are some misunderstandings of this talent needs trauma perspective with some research focusing excessively or incorrectly on the incidence of life and sport challenge as a feature of effective talent development. The objective of the study was to examine what factors associated with such trauma experiences may or may not discriminate between high, medium and low achievers in sport, classified as super-champions, champions or almosts. A series of retrospective interviews were used with matched triads (i.e., super-champions, champions or almosts of performers (N = 54 from different sports. Data collection was organized in three phases. In the first phase, a graphic time line of each performer’s career was developed. The second phase explored the specific issues highlighted by each participant in a chronological sequence. The third phase was a retrospective reflection on traumatic motivators, coach/significant other inputs and psychological challenges experienced and skills employed. Data suggested qualitative differences between categories of performers, relating to several perceptual and experiential features of their development. No evidence was found for the necessity of major trauma as a feature of development. There was a lack of discrimination across categories of performers associated with the incidence of trauma and, more particularly, life or non-sport trauma. These findings suggest that differences between levels of adult achievement relate more to what performers bring to the challenges than what they experience. A periodized and progressive set of challenge, preceded and associated with specific skill development, would seem to offer the best pathway to success for the

  10. Theoretical considerations in solid bowl centrifugation

    International Nuclear Information System (INIS)

    Hamilton, R.T.

    1979-01-01

    A combination of literature survey and independent analysis determined three relationships for the prediction of the critical (or minimum recoverable) particle size in a solid bowl centrifuge. The relationships were derived based on three different theories of fluid behavior within the centrifuge; (1) laminar film flow (laminar film model), (2) plug flow (Sharples Model), and parabolic flow (modified Sharples Model). The critical particle size for the centrifuge used in Cs-PTA recovery in the CAW process predicted by the three relationships range from 0.19 to 0.34 μm (1 μm = 10 -6 m). The laminar film model gives the most conservative estimate of critical particle size (0.34 μm) and the resulting relationship is recommended for use to predict solid bowl centrifuge performance. Three correction factors are incorporated into the predictive equations to account for the effects of fluid turbulence near the centrifuge feed point, fluid lag and hindered settling. Of these factors, turbulence near the feed point (which is accounted for by using an effective centrifuge length) has the greatest impact, increasing the predicted critical particle size by 15%, while the combination of fluid lag and hindered settling factors increase the recoverable particle size by 4%. The overall effect of the correction factors is an approximately 20% decrease in centrifuge effectivity. The fraction of solids smaller than the critical size range has not been reliably determined for laboratory or plant prepared Cs-PTA. In addition, the density of Cs-PTA crystals is reported to vary from 3.2 to 12 grams per cubic centimeter

  16. Champions and e-books: using student Library Champions to inform e-book purchasing strategies

    Directory of Open Access Journals (Sweden)

    2016-07-01

    Full Text Available How students really use e-books is a subject of much interest to library professionals. This has particular relevance when it comes to selecting suppliers and e-book platforms for institutional use. The question of preferred formats (print versus digital has been asked exhaustively, but technology develops fast and is here to stay in higher education, so a more pressing question is how we evaluate which platforms offer the best user experience for our students. At the University of Exeter we used our student Library Champion volunteers as a focus group, repeating the process over two years, to help determine which platforms were preferred. Champions examined multiple interfaces, but concentrated primarily on aggregators. They were encouraged to use their own laptops and tablets to access the e-books, which proved particularly valuable as it allowed interfaces to be rated for their compatibility across devices. Positive and negative feedback was collated, sent to providers and also used directly to inform and alter the Library’s purchasing preference list.

The structure of the representative molecular bowl 5 was confirmed by single-crystal X-ray diffraction analysis. The anticancer activities of molecular bowls 5–7 were determined by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide, autophagy, and Western blot analysis. Bowl 6 showed the strongest cytotoxicity in AGS human gastric carcinoma cells and was more cytotoxic than doxorubicin. In addition, autophagic activity and the ratio of apoptotic cell death increased in AGS cells by treatment with bowl 6. Bowl 6 also induced autophagosome formation via upregulation

    Brownish bowl originating from an underwater shipwreck located near Belitung island in the Java Sea, some 600 km south-east from Singapore, has been measured with particle induced X-ray emission. This study was a pilot project for the - now a spin-off company - Recenart research team where one target was to evaluate the authenticity of the different type of art objects. PIXE measurements were done from three different material positions from a single bowl received from a customer. These locations were categorized as a bluish/greenish pigment (under glaze), thick glaze and the body clay. When the obtained data was compared to the other references from different dynasties and kiln sites, the closest match was indeed the Tang dynasty, Tongguan/Ghangsha kiln-site potsherds - from where the bowl in question was also suspected to originate.

    Full Text Available Extraverted children are hypothesized to be most at risk for over-serving and overeating due to environmental cues--such as the size of dinnerware. A within-subject field study of elementary school students found that extraverted children served themselves 33.1% more cereal in larger bowls (16-oz than in smaller (12-oz bowls, whereas introverted children were unaffected by bowl size (+5.6%, ns. However, when children were asked by adults how much cereal they wanted to eat, both extraverted and introverted children requested more cereal when given a large versus small bowl. Insofar as extraverted children appear to be more biased by environmental cues, this pilot study suggests different serving styles are recommended for parents and other caregivers. They should serve extraverts, but allow introverts to serve themselves. Still, since the average child still served 23.2% more when serving themselves than when served by an adult, it might be best for caregivers to do the serving whenever possible--especially for extraverted children.

  14. What makes champions? A review of the relative contribution of genes and training to sporting success.

    Science.gov (United States)

    Tucker, Ross; Collins, Malcolm

    2012-06-01

    Elite sporting performance results from the combination of innumerable factors, which interact with one another in a poorly understood but complex manner to mould a talented athlete into a champion. Within the field of sports science, elite performance is understood to be the result of both training and genetic factors. However, the extent to which champions are born or made is a question that remains one of considerable interest, since it has implications for talent identification and management, as well as for how sporting federations allocate scarce resources towards the optimisation of high-performance programmes. The present review describes the contributions made by deliberate practice and genetic factors to the attainment of a high level of sporting performance. The authors conclude that although deliberate training and other environmental factors are critical for elite performance, they cannot by themselves produce an elite athlete. Rather, individual performance thresholds are determined by our genetic make-up, and training can be defined as the process by which genetic potential is realised. Although the specific details are currently unknown, the current scientific literature clearly indicates that both nurture and nature are involved in determining elite athletic performance. In conclusion, elite sporting performance is the result of the interaction between genetic and training factors, with the result that both talent identification and management systems to facilitate optimal training are crucial to sporting success.

    The idea that champions are crucial to effective healthcare-related implementation has gained broad acceptance; yet the champion construct has been hampered by inconsistent use across the published literature. This integrative review sought to establish the current state of the literature on champions in healthcare settings and bring greater clarity to this important construct. This integrative review was limited to research articles in peer-reviewed, English-language journals published from 1980 to 2016. Searches were conducted on the online MEDLINE database via OVID and PubMed using the keyword "champion." Several additional terms often describe champions and were also included as keywords: implementation leader, opinion leader, facilitator, and change agent. Bibliographies of full-text articles that met inclusion criteria were reviewed for additional references not yet identified via the main strategy of conducting keyword searches in MEDLINE. A five-member team abstracted all full-text articles meeting inclusion criteria. The final dataset for the integrative review consisted of 199 unique articles. Use of the term champion varied widely across the articles with respect to topic, specific job positions, or broader organizational roles. The most common method for operationalizing champion for purposes of analysis was the use of a dichotomous variable designating champion presence or absence. Four studies randomly allocated of the presence or absence of champions. The number of published champion-related articles has markedly increased: more articles were published during the last two years of this review (i.e. 2015-2016) than during its first 30 years (i.e. 1980-2009).The number of champion-related articles has continued to increase sharply since the year 2000. Individual studies consistently found that champions were important positive influences on implementation effectiveness. Although few in number, the randomized trials of champions that have been

  16. Simulating US Agriculture in a Modern Dust Bowl Drought

    Glotter, Michael; Elliott, Joshua

    2016-01-01

    Drought-induced agricultural loss is one of the most costly impacts of extreme weather, and without mitigation, climate change is likely to increase the severity and frequency of future droughts. The Dust Bowl of the 1930s was the driest and hottest for agriculture in modern US history. Improvements in farming practices have increased productivity, but yields today are still tightly linked to climate variation and the impacts of a 1930s-type drought on current and future agricultural systems remain unclear. Simulations of biophysical process and empirical models suggest that Dust-Bowl-type droughts today would have unprecedented consequences, with yield losses approx.50% larger than the severe drought of 2012. Damages at these extremes are highly sensitive to temperature, worsening by approx.25% with each degree centigrade of warming. We find that high temperatures can be more damaging than rainfall deficit, and, without adaptation, warmer mid-century temperatures with even average precipitation could lead to maize losses equivalent to the Dust Bowl drought. Warmer temperatures alongside consecutive droughts could make up to 85% of rain-fed maize at risk of changes that may persist for decades. Understanding the interactions of weather extremes and a changing agricultural system is therefore critical to effectively respond to, and minimize, the impacts of the next extreme drought event.

    A champion of research paper at JAERI and those of foreign prestigious nuclear research institutes (5 from the U.S., 3 from the France and 2 from the Germany) was studied taking the timeframe as long as 30 years (1978-2007) Tools for this bibliometric study were INIS, ECD, WOS and SCOPUS. The former two were general database collected all papers related to nuclear, while the latter two were specified database collected research papers submitted to journals for natural, social sciences and human learning. (1) INIS for the world-wide general tool focused on nuclear judged that JAERI (32,859 papers) was the champion and ORNL (32,395 papers) was the second position. (2) ECD for the US-oriented energy database judged that the ranking was of the order of ORNL(36,608 papers), ANL(26,530) and SNL(24,687). (3) The trend observed in the WOS for the US-oriented database roughly coincided with that of ECD, where ORNL(34,331 papers) was the champion, where JAERI was the 7th position. (4) SCOPUS, basically originated from the Europe judged that that ORNL (32,728 papers) was the champion, where JAERI (16,860) was the 7th position. (5) Different characteristics exhibited by individual databases can sometimes generate conflicting bibliometric results. This was true among INIS, ECD, WOS and SCOPUS when looking at trends between 5-year periods. It implies that results from analytical tools used in bibliometric studies should be viewed with careful consideration to learn of any influencing factors. (6) Use of INIS has predominance in Japan, and use of ECD has predominance in the U.S. Users from developed and developing countries assigned as the Member State of IAEA would be better served using INIS and ECD as the intellectual data source. As the recent trend, WOS and SCOPUS are used as the evaluation tools. (author)

  18. Outreach for Families and Girls- Astronomy at Outdoor Concerts and at Super Bowl or Halloween Star Parties

    Bring telescope to where the people are! Music and Astronomy Under the Stars (MAUS) is a NASA-funded as astronomy outreach program at community parks and music festivals (1000 - 25,000 people/event). While there have been many astronomy outreach activities and telescope observations at sidewalks and parks, this program targets a different audience - music lovers who are attending concerts in community parks or festivals. These music lovers who may not have visited science museums, planetariums, or star parties are exposed to telescope observations and astronomy information with no additional travel costs. MAUS includes solar observing, telescope observations including a live imaging system, an astronomical video, astronomy banners/posters, and hands-on activities. MAUS increased awareness, engagement, and interest in astronomy at classical, pop, rock, and ethnic music concerts. Since 2009 over 50,000 people have participated in these outreach activities including a significant number of families and young girls. In addition to concerts in local Long Island parks, there were MUAS events at Tanglewood (summer home of the Boston Symphony Orchestra), Jazz in Central Park, and Astronomy Night on the National Mall (co-sponsored by the White House Office of Science and Technology Policy). In 2011 MUAS will be expanded to include Ravinia (summer home of the Chicago Symphony Orchestra), the Newport Folk Festival, and the Bethel Woods Center for the Arts (site of the 1969 Woodstock festival). According to our survey results, music lovers became more informed about astronomy. Expanding Hofstra University's successful outreach programs, I propose the creation of a National Halloween Stars event targeting children and a National Super Bowl Star Party targeting girls, women, and the 2/3 of Americans who do not watch the Super Bowl. This can be combined with astronomers or amateur astronomers bringing telescopes to Super Bowl parties for football fans to stargaze during

    Full Text Available Over the past twenty years, research on textile has received increasing attention in archaeology worldwide, providing new insights into one of the most important crafts in human history. In contrast, activities related to spinning and weaving in the Late Neolithic settlements in the Central Balkans have only be treated with cursory attention, which has resulted in nothing more than a set of general assumptions in archaeological literature. Though some progress has recently been made, investigations of textile in prehistoric contexts are still far from their full potential. The quest for spinning bowls in ceramic assemblages constitutes an important part of the given research, providing new evidence on the production of both textiles and pottery. Therefore, the focus of this paper is on the available evidence for those activities related to textile production in the Late Neolithic, primarily to spinning, with special emphasis on the earliest occurrence of spinning bowls in the Central Balkans i.e. the technology of wetting and tightening plant fibres in ceramic vessels.

    Transcranial magnetic stimulation (TMS) has recently been used as a method for the treatment of neurological and psychiatric diseases. Daily TMS sessions can provide continuous therapeutic effectiveness, and the installation of TMS systems at patients' homes has been proposed. A figure-eight coil, which is normally used for TMS therapy, induces a highly localized electric field; however, it is challenging to achieve accurate coil positioning above the targeted brain area using this coil. In this paper, a bowl-shaped coil for stimulating a localized but wider area of the brain is proposed. The coil's electromagnetic characteristics were analyzed using finite element methods, and the analysis showed that the bowl-shaped coil induced electric fields in a wider area of the brain model than a figure-eight coil. The expanded distribution of the electric field led to greater robustness of the coil to the coil-positioning error. To improve the efficiency of the coil, the relationship between individual coil design parameters and the resulting coil characteristics was numerically analyzed. It was concluded that lengthening the outer spherical radius and narrowing the width of the coil were effective methods for obtaining a more effective and more uniform distribution of the electric field.

  1. An Ecocritical Reading of Paul Bowles's The Sheltering Sky

    2017-07-01

    Full Text Available Landscapes are not simply something objective and unchallenged out there but the work of the mind made by the strata of memory. This paper attempts to show that an ecocritical reading of Paul Bowles’s The Sheltering Sky (1949 helps one in better understanding of this novel of post-colonial alienation and existential despair. Bowles is an American writer and a composer who is undoubtedly the most arresting example of cross-cultural influence concerning a Western author and the Middle East and North Africa.  His fiction mostly focuses on American expatriates travelling in exotic locations. The Sheltering Sky is an encounter with the Sahara, not only the physical one but the desert of moral nihilism into which one may wander blindly. The boundless desert acts here as a metaphor and the journey symbolizes one’s own journey into the depth of his/her soul. The desert also projects an apocalyptic vision in the struggle between the West and the East and the Sahara becomes in fact a Conradian Heart of Darkness, an Eliotian Waste Land, and a Sartrean No Exit. In the novel the actual environment becomes in some ways pale and covert under the psyche of the writer. Consequently we come to know that Bowles's own knowledge and awareness of the same environments left traces in his work. Accordingly we may wrap up that the environment bears a direct impact on our understanding of it.

  4. The Evolution of Champion Cross-Country-Skier Training: From Lumberjacks to Professional Athletes.

    2017-02-01

    Competitive cross-country (XC) skiing has traditions extending back to the mid-19th century and was included as a men's event in the first Winter Games in 1924. Since then, tremendous improvements in equipment, track preparation, and knowledge about training have prompted greater increases in XC-skiing speeds than in any other Olympic sport. In response, this commentary focuses on how the training of successful XC skiers has evolved, with interviews and training data from surviving Norwegian world and Olympic XC champions as primary sources. Before 1970, most male champion XC skiers were lumberjacks who ran or skied long distances to and from felling areas while working long days in the woods. In addition, they trained as much as possible, with increased intensity during the autumn, while less work but more ski-specific training and competitions were done during the winter. Until the 1970s, few XC skiers were women, whom coaches believed tolerated less training than men did. Today's XC skiers are less physically active, but the influence of both science and the systematic approaches of former athletes and coaches have gradually taught XC skiers to adopt smarter, more goal-oriented training practices. Although the very high VO 2 max of world-class XC skiers has remained the same since the 1960s, new events in modern XC skiing have additionally required superior upper-body power, high-speed techniques, and tactical flexibility. These elements also emerge in the training of today's best skiers; women's physiological capacities and training routines especially seem to have improved dramatically.

    Grgic, J and Mikulic, P. Tapering practices of Croatian open-class powerlifting champions. J Strength Cond Res 31(9): 2371-2378, 2017-The aim of this study was to explore tapering practices among 10 Croatian open-class powerlifting champions (mean ± SD: age 29.2 ± 3.2 years; Wilks coefficient 355.1 ± 54.8). The athletes were interviewed about their tapering practices using a semi-structured interview after which the audio content was transcribed. The athletes reported decreasing training volume during the taper by 50.5 ± 11.7% using a step type or an exponential type of taper with a fast decay. Training intensity was maintained or increased during the taper, and it reached its highest values 8 ± 3 days before the competition. Training frequency was reduced or maintained during the taper. The final week included a reduction in training frequency by 47.9 ± 17.5% with the last training session performed 3 ± 1 days before the competition. The participants typically stated that the main reasons for conducting the taper were maintaining strength and reducing the amount of fatigue. They also stated that (a) the taper was structured identically for the squat, bench press, and the deadlift; (b) the training during the taper was highly specific, the assistance exercises were removed, and the same equipment was used as during competition; (c) the source of information for tapering was their coach, and training fluctuated based on the coach's feedback; and (d) nutrition, foam rolling, static stretching, and massage were all given extra attention during the taper. These results may aid athletes and coaches in strength sports in terms of the optimization of tapering variables.

    2005-04-01

    It's hard to find a better exemplar for competition than chess. The image of two brilliant minds locked in a battle of skill and will-in which chance plays little or no apparent role-is compelling. Even people who have scant knowledge of the game instinctively recognize that chess is unusual in terms of its intellectual complexity and the strategic demands it places on players. Can strategists learn anything from chess players about what it takes to win? To find out, H BR senior editor Diane L. Coutu talked with Garry Kasparov, the world's number one player since 1984. Kasparov believes that success in both chess and business is very much a question of psychological advantage; the complexity of the game demands that players rely heavily on their instincts and on gamesmanship. In this wide-ranging interview, Kasparov explores the power of chess as a model for business competition; the balance that chess players strike between intuition and analysis; the significance of his loss to IBM's chess-playing computer, Deep Blue; and how his legendary rivalry with Anatoly Karpov, Kasparov's predecessor as World Chess Champion, affected his own success. Kasparov also shares his solution to what he calls the champion's dilemma, a question for all world masters, whether they are in business, sports, or chess: Where does a virtuoso go after he has accomplished everything he's ever wanted to, even beyond his wildest imagination? If you are lucky, says Kasparov, your enemies will push you to be passionate about staying at the top.

    2009-05-15

    This study presents some results from the numerical simulation of the flow in an industrial solid bowl centrifuge used for particle separation in industrial fluid processing. The computational fluid dynamics (CFD) software Fluent was used to simulate this multiphase flow. Simplified two-dimensional and three-dimensional geometries were built and meshed from the real centrifuge geometry. The CFD results show a boundary layer of axially fast moving fluid at the gas-liquid interface. Below this layer there is a thin recirculation. The obtained tangential velocity values are lower than the ones for the rigid-body motion. Also, the trajectories of the solid particles are evaluated.

    The controlled reaction of Na and Cs, two alkali metals of different ionic sizes and binding abilities, with sumanene (C{sub 21}H{sub 12}) affords a novel type of organometallic sandwich [Cs(C{sub 21}H{sub 11}{sup -}){sub 2}]{sup -}, which crystallized as a solvent-separated ion pair with a [Na(18-crown-6)(THF){sub 2}]{sup +} cation (where THF=tetrahydrofuran). The unprecedented double concave encapsulation of a metal ion by two bowl-shaped sumanenyl anions in [Cs(C{sub 21}H{sub 11}{sup -}){sub 2}]{sup -} was revealed crystallographically. Evaluation of bonding and energetics of the remarkable product was accomplished computationally (B2PLYP-D/TZVP/ZORA), providing insights into its formation.

    1. Bowl and pan traps are now commonly used to capture bees (Hymenoptera: Apiformes) for research and surveys. 2. Studies of how arrangement and spacing of bowl traps affect captures of bees are needed to increase the efficiency of this capture technique. 3. We present results from seven studies of bowl traps placed in trapping webs, grids, and transects in four North American ecoregions (Mid-Atlantic, Coastal California, Chihuahuan Desert, and Columbia Plateau). 4. Over 6000 specimens from 31 bee genera were captured and analysed across the studies. 5. Based on the results from trapping webs and distance tests, the per bowl capture rate of bees does not plateau until bowls are spaced 3–5 m apart. 6. Minor clumping of bee captures within transects was detected, with 26 of 56 transects having index of dispersion values that conform to a clumped distribution and 39 transects having positive Green's index values, 13 with zero, and only four negative. However, degree of clumping was slight with an average value of only 0.06 (the index ranges from -1 to 1) with only five values >0.15. Similarly, runs tests were significant for only 5.9% of the transects. 7. Results indicate that (i) capture rates are unaffected by short distances between bowls within transects and (ii) that bowls and transects should be dispersed throughout a study site.

    Full Text Available In this paper some results concerning the evolution of 3D fluid flow pattern through all four strokes in combustion chambers with entirely different bowl-in-piston geometry layouts ranging from ”omega” to “simple cylinder” were presented. All combustion chambers i.e. those with „omega“ bowls, with different profiles, and those with „cylinder“ bowls, with different squish area ranging from 44% to 62%, were with flat head, vertical valves and identical elevation of intake and exhaust ports. A bunch of results emerged by dint of multidimensional modeling of nonreactive fluid flow in arbitrary geometry with moving objects and boundaries. The fluid flow pattern during induction and compression in all cases was extremely complicated and entirely three-dimensional. It should be noted that significant differences due to geometry of the bowl were encountered only in the vicinity of TDC. Namely, in the case of “omega” bowl all three types of organized macro flows were observed while in the case of “cylinder” bowl no circumferential velocity was registered at all. On the contrary, in the case of “cylinder” bowl some interesting results concerning reverse tumble and its center of rotation shifting from exhaust valve zone to intake valve zone during induction stroke and vice-verse from intake valve zone to exhaust valve zone during compression were observed while in the case of “omega” bowl no such a displacement was legible. During expansion the fluid flow pattern is fully controlled by piston motion and during exhaust it is mainly one-dimensional, except in the close proximity of exhaust valve. For that reason it is not affected by the geometry of the bowl.

  11. The development of a novel cricket bowling system: recreating spin and swing bowling deliveries at the elite level

    During the game of cricket, bowlers create different deliveries by altering the manner in which they release the ball from their hand. The orientation of the seam, the speed at which the ball is released and the magnitude and direction of the spin combine to determine the motion of the ball through the air and its movement after impact with the wicket. These factors have to be considered if automatic training machines are to be capable of replicating elite bowling deliveries. The need for automotive systems for batting and fielding training at the elite level has arisen due to: (i) the capabilities of human bowlers are limited by the onset of fatigue and the risk of injury and (ii) a large number of accurate and repeatable deliveries to be ''programmable'' by coaches to ensure batsmen and fielders are tested to the limits of their abilities and a training benefit is achieved.

    In healthcare there is a long held wisdom that 'champions' are a key aspect of organizational change. Drawing on organizational management theory, we examine the role of champions in three health and social care organizations in England as they attempt to move services to a remote model of delivery, 'telecare'. The delivery of remote care is a significant policy in the U.K. and elsewhere, but its introduction has been challenging. Over three years ethnographic methods (observations, informed discussions and interviews) were used to analyze the role of organizational champions in implementing remote care. Cases were local authorities and associated primary care trusts. Participants were champions and organizational members involved in implementation. Our study shows that organizational champions are highly effective in the first phase of adoption, when change is contained within distinct sub-sets of practice. Moving beyond local contexts the effectiveness of the champions varied. Identification centered on the remote care work. This identification enabled the champions to motivate others and move beyond their normally prescribed roles, contributing to innovation ideas, processes and practices. When required to shift their work organization-wide, and share ideas outside their professional culture, some champions responded with resistance, resulting in a lack of innovation spread. These results caution against allowing change to become positioned within the remit of a few individuals. Whilst this strategy may be initially beneficial, the role of champion may be less useful, even detrimental to progress, in the later stages of implementation, particularly if identification with the new circumstances is not established.

    Athletes' kinanthropometric profiles are widely addressed in the scientific literature. Such profiles are particularly important in volleyball because absolute size contributes a significant percentage of total variance associated with athletic success. As in other team sports, volleyball players' kinanthropometric attributes correlate with the game's tactical demands. From 1992 through 2000, the Cuban women's volleyball team achieved top global performance, winning first place in three successive Summer Olympic Games. Describe the kinanthropometric profiles of Cuban women Olympic volleyball champions during 1992-2000 and compare these by position played. Measurements were taken of body composition, somatotype, proportionality and several anthropometric indicators in 41 Cuban women volleyball players, grouped by playing position. All were members of the national team that participated in the Summer Olympic Games in Barcelona (1992), Atlanta (1996) and Sydney (2000). Mean and standard deviations were calculated for all study variables. Analysis of variance was used to compare means for different positions for the variables weight; height; percent adipose, muscle and bone mass; body mass index; and muscle-to-bone ratio. Discriminant analysis was performed to identify anthropometric dimensions differentiating playing positions (center, spiker and setter), using pvolleyball players was balanced mesomorphic (2.7-3.6-2.9). Classified by position, centers (2.9-3.4-3.4) and spikers (2.8-3.6-2.9) presented an average mesomorphic-ectomorphic somatotype, and setters (2.6-3.7-2.6) were balanced mesomorphic. On assessing Somatotype Attitudinal Mean (SAM), centers and spikers showed more intrapositional homogeneity than that of setters. Centers were significantly taller (187.1±2.5 cm) than players in other positions. Centers' percent adipose tissue mass (28.9±2.7%) was significantly higher than that of setters (24.3±2.7%), who were leanest of all positions. The

    Full Text Available Evaluation champions are individuals who serve as catalysts for building evaluation capacity within an organization. They advocate for the importance of program evaluation, model good evaluation behaviors, and mentor their peers in program evaluation skills and competencies. Interviews with 40 peer-nominated champions in four purposively-sampled Extension organizations identified the roles, contexts, and motivations of staff who act as evaluation champions. Findings underline the importance—and the limits—of mentors and project teams in building evaluation capacity in complex organizations. Implications for practice, research, and policy are discussed

    Full Text Available Abstract Background Previous studies have reported that the design of the water dispensers can influence the water intake in farm animals. Horses and dairy cows seem to prefer to drink from an open surface whereas sheep and pigs apparently prefer water nipples, probably because of the worse water quality in water bowls. The aim of the present study was to examine the preference of dairy goats for water nipples or water bowls. Methods In each of the two experiments (exp. 1, dry goats, exp. 2 lactating goats, 42 dairy goats were allotted into 6 groups of 7 goats. In period 1, the goats had access to a water nipple. In period 2, they had access to a water bowl and in period 3 (preference test they had access to both a water nipple and a water bowl. Water usage and wastage was recorded and water intake (water usage - water wastage was calculated for each group for the two last days of each period. In experiment 2, water samples from each dispenser were analyzed for heterotrophy germs at 22°C, Escherichia coli and turbidity. Results Water usage was higher from water nipples than from water bowls both in experiment 1 (dry goats and experiment 2 (lactating goats. There was however, no difference in water intake from water nipples and water bowls. In the preference test (period 3, the water intake tended to be higher from the water nipple than from the water bowl both for the dry goats (exp. 1 and lactating goats (exp. 2. Especially for the dry goats, the differences between groups were large. Turbidity and heterotrophy germs were much higher in the samples from the water bowls than from the water nipples. Water wastage from the water bowls was negligible compared to the water nipples. From the water nipples the water wastage was 30% and 23% of water usage for the dry and lactating goats respectively. Conclusions We conclude that type of water dispenser (nipple or bowl was probably of minor importance for water intake in goats, but water bowls had a

    To date, scientific investigations into the biomechanical aspects of cricket fast bowling techniques have predominantly focused on identifying the mechanical factors that may predispose fast bowlers to lower back injury with a relative paucity of research being conducted on the technical features that underpin proficient fast bowling performance. In this review paper, we critique the scientific literature examining fast bowling performance. We argue that, although many published investigations have provided some useful insights into the biomechanical factors that contribute to a high ball release speed and, to a lesser extent, bowling accuracy, this research has not made a substantive contribution to knowledge enhancement and has only had a very minor influence on coaching practice. To significantly enhance understanding of cricket fast bowling techniques and, therefore, have greater impact on practice, we recommend that future scientific research adopts an interdisciplinary focus, integrating biomechanical measurements with the analytical tools and concepts of dynamical systems motor control theory. The use of qualitative (topological) analysis techniques, in particular, promises to increase understanding of the coordinative movement patterns that define 'technique' in cricket fast bowling and potentially help distinguish between functional and dysfunctional aspects of technique for individual fast bowlers.

    Full Text Available In recent years bowl traps have gained attention as a useful method for sampling bees and are now commonly used across the world for this purpose. However, specific questions about the method itself have not yet been tested on different regions of the globe. We present the preliminary results of bowl trapping in a Semidecidual Seasonal forest fragment in southern Brazil, including the test of two different color bowls, two different habitats, and the interaction of these variables in bee species number and composition. We used blue and yellow bowls in the border and in the core trails of the forest fragment. In five sampling days between October to December bowl traps captured 745 specimens of 37 morphospecies, with Halictinae bees being the richest and most abundant group. Non parametrical statistical analyses suggested that different colors of bowl traps influenced bee richness and composition and thus, they should be used together for a more complete sampling. Different trails influenced only the composition, while the interaction with different colors did not have a significant effect. These results, as well as the higher taxonomic composition of the inventoried bees, are similar to other studies reported in the literature.

  19. Effect of Ball Weight on Speed, Accuracy, and Mechanics in Cricket Fast Bowling

    Full Text Available The aims of this study were: (1 to quantify the acute effects of ball weight on ball release speed, accuracy, and mechanics in cricket fast bowling; and (2 to test whether a period of sustained training with underweight and overweight balls is effective in increasing a player’s ball release speed. Ten well-trained adult male cricket players performed maximum-effort deliveries using balls ranging in weight from 46% to 137% of the standard ball weight (156 g. A radar gun, bowling target, and 2D video analysis were used to obtain measures of ball speed, accuracy, and mechanics. The participants were assigned to either an intervention group, who trained with underweight and overweight balls, or to a control group, who trained with standard-weight balls. We found that ball speed decreased at a rate of about 1.1 m/s per 100 g increase in ball weight. Accuracy and bowling mechanics were not adversely affected by changes in ball weight. There was evidence that training with underweight and overweight balls might have produced a practically meaningful increase in bowling speed (>1.5 m/s in some players without compromising accuracy or increasing their risk of injury through inducing poor bowling mechanics. In cricket fast bowling, a wide range of ball weight might be necessary to produce an effective modified-implement training program.

    King's Bowl (KB) and its associated eruptive fissure and lava field on the eastern Snake River Plain, is being investigated by the NASA SSERVI FINESSE (Field Investigations to Enable Solar System Science and Exploration) team as a planetary analog to similar pits on the Moon, Mars and Vesta. The 2,220 ± 100 BP basaltic eruption in Craters of the Moon National Monument and Preserve represents early stages of low shield growth, which was aborted when magma supply was cut off. Compared to mature shields, KB is miniscule, with ~0.02 km3 of lava over ~3 km2, yet the ~6 km long series of fissures, cracks and pits are well-preserved for analog studies of volcanic processes. The termination of eruption was likely related to proximity of the 2,270 ± 50 BP eruption of the much larger Wapi lava field (~5.5 km3 over 325 km2 area) on the same rift. Our investigation extends early work by R. Greeley and colleagues, focusing on imagery, compositional variations, ejecta distribution, dGPS profiles and LiDAR scans of features related to: (1) fissure eruptions - spatter ramparts, cones, feeder dikes, extension cracks; (2) lava lake formation - surface morphology, squeeze-ups, slab pahoehoe lava mounds, lava drain-back, flow lobe overlaps; and (3) phreatic steam blasts - explosion pits, ejecta blankets of ash and blocks. Preliminary results indicate multiple fissure eruptions and growth of a basin-filled lava lake up to ~ 10 m thick with outflow sheet lava flows. Remnant mounds of original lake crust reveal an early high lava lake level, which subsided as much as 5 m as the molten interior drained back into the fissure system. Rapid loss of magma supply led to the collapse of fissure walls allowing groundwater influx that triggered multiple steam blasts along at least 500 m. Early blasts occurred while lake magma pressure was still high enough to produce squeeze-ups when penetrated by ejecta blocks. The King's Bowl pit crater exemplifies processes of a small, but highly energetic

    The Master-Lee and the modified Champion 4 Inch hydraulic cutters are being retested to gather and document information related to the following: determine if the Master-Lee cutters will cut the trunnions of an Aluminum fuel canister and a Stainless Steel fuel canister; determine if the Master-Lee cutters will cut 1 1/2 inch diameter fire hose; determine if the modified Champion 4 inch blade will cut sections of piping; and determine the effectiveness of the centering device for the Champion 4 Inch cutters. Determining the limitations of the hydraulic cutter will aid in the process of debris removal in the K-Basin. Based on a previous test, the cutters were returned to the manufacturer for modifications. The modifications to the Champion 4 Inch Cutter and further testing of the Master-Lee Cutter are the subjects of these feature tests

The decline in performance among national champion swimmers, both men and women and in short and long swims, is linear, at about 0.6% per year up to age 70–75, after which it accelerates in quadratic fashion. These conclusions are based primarily on cross-sectional studies, and little is known about individual performance declines with aging. Herein we present performance profiles of 19 male and 26 female national and international champion Masters swimmers, ages 25 to 96 years, participating in competitions for an average of 23 years. Methods and results: Swimmers’ longitudinal data were compared with the fastest times of world record holders across ages 35–100 years by two regression methods. Neither method proved to accurately model this data set: compared with the rates of decline estimated from the world record data, which represent the best recorded times at given ages, there was bias toward shallower rates of performance decline in the longitudinal data, likely owing to a practice effect in some swimmers as they began their Masters programs. In swimmers’ later years, once maximum performance had been achieved, individual profiles followed the decline represented in the world records, and a few swimmers became the world record holders.

  5. Champions for social change: Photovoice ethics in practice and 'false hopes' for policy and social change.

    2016-01-01

    Photovoice methodology is growing in popularity in the health, education and social sciences as a research tool based on the core values of community-based participatory research. Most photovoice projects state a claim to the third goal of photovoice: to reach policy-makers or effect policy change. This paper examines the concerns of raising false hopes or unrealistic expectations amongst the participants of photovoice projects as they are positioned to be the champions for social change in their communities. The impetus for social change seems to lie in the hands of those most affected by the issue. This drive behind collective social action forms, what could be termed, a micro-social movement or comparative interest group. Looking to the potential use of social movement theory and resource mobilisation concepts, this paper poses a series of unanswered questions about the ethics of photovoice projects. The ethical concern centres on the focus of policy change as a key initiative; yet, most projects remain vague about the implementation and outcomes of this focus.

    A numerical study was carried out to study the effect of various combustion bowl parameters on the performance behavior, combustion characteristics, and emission magnitude on a single cylinder diesel engine. A base combustion bowl and 11 different combustion bowls were created by varying the aspect ratio, reentrancy ratio, and bore to bowl ratio. The study was carried out at engine rated speed and a full throttle performance condition, without altering the compression ratio. The results revealed that the combustion bowl parameters could have a huge impact on the performance behavior, combustion characteristics, and emission magnitude of the engine. The bowl parameters, namely throat diameter and toroidal radius, played a crucial role in determining the performance behavior of the combustion bowls. It was observed that the combustion bowl parameters, namely central pip distance, throat diameter, and bowl depth, also could have an impact on the combustion characteristics. And throat diameter and toroidal radius, central pip distance, and toroidal corner radius could have a consequent effect on the emission magnitude of the engine. Of the different combustion bowls tested, combustion bowl 4 was preferable to others owing to the superior performance of 3% of higher indicated mean effective pressure and lower fuel consumption. Interestingly, trade-off for NO x emission was higher only by 2.85% compared with the base bowl. The sensitivity analysis proved that bowl depth, bowl diameter, toroidal radius, and throat diameter played a vital role in the fuel consumption parameter and emission characteristics even at the manufacturing tolerance variations.

    Context Self-report questionnaires are an important method of evaluating lifespan health, exercise, and health-related quality of life (HRQL) outcomes among elite, competitive athletes. Few instruments, however, have undergone formal characterization of their psychometric properties within this population. Objective To evaluate the validity and reliability of a novel health and exercise questionnaire, the Trojan Lifetime Champions (TLC) Health Survey. Design Descriptive laboratory study. Setting A large National Collegiate Athletic Association Division I university. Patients or Other Participants A total of 63 university alumni (age range, 24 to 84 years), including former varsity collegiate athletes and a control group of nonathletes. Intervention(s) Participants completed the TLC Health Survey twice at a mean interval of 23 days with randomization to the paper or electronic version of the instrument. Main Outcome Measure(s) Content validity, feasibility of administration, test-retest reliability, parallel-form reliability between paper and electronic forms, and estimates of systematic and typical error versus differences of clinical interest were assessed across a broad range of health, exercise, and HRQL measures. Results Correlation coefficients, including intraclass correlation coefficients (ICCs) for continuous variables and κ agreement statistics for ordinal variables, for test-retest reliability averaged 0.86, 0.90, 0.80, and 0.74 for HRQL, lifetime health, recent health, and exercise variables, respectively. Correlation coefficients, again ICCs and κ, for parallel-form reliability (ie, equivalence) between paper and electronic versions averaged 0.90, 0.85, 0.85, and 0.81 for HRQL, lifetime health, recent health, and exercise variables, respectively. Typical measurement error was less than the a priori thresholds of clinical interest, and we found minimal evidence of systematic test-retest error. We found strong evidence of content validity, convergent

    The objective of the study was to evaluate two types of cricket bowling techniques by comparing the lumbar spinal loading using a musculoskeletal modelling approach. Three-dimensional kinematic data were recorded by a Vicon motion capture system under two cricket bowling conditions: (1) participants bowled at their absolute maximal speeds (max condition), and (2) participants bowled at their absolute maximal speeds while simultaneously forcing their navel down towards their thighs starting just prior to ball release (max-trunk condition). A three-dimensional musculoskeletal model comprised of the pelvis, sacrum, lumbar vertebrae and torso segments, which enabled the motion of the individual lumbar vertebrae in the sagittal, frontal and coronal planes to be actuated by 210 muscle-tendon units, was used to simulate spinal loading based on the recorded kinematic data. The maximal lumbar spine compressive force is 4.89 ± 0.88BW for the max condition and 4.58 ± 0.54BW for the max-trunk condition. Results showed that there was no significant difference between the two techniques in trunk moments and lumbar spine forces. This indicates that the max-trunk technique may not increase lower back injury risks. The method proposed in this study could be served as a tool to evaluate lower back injury risks for cricket bowling as well as other throwing activities.

A new archaeological classification of this well-known group of Archaic ceramics of eastern Greece is presented. A number of kiln wasters of misfired vessels from Kalabaktepe revealed a characteristic local pattern. This pattern helped to clarify the provenance of some of the bird bowls classified archaeologically as of orientalizing type: they have been made in Miletus. But bird kotylai and bird bowls in the ''standard fabric'' as well as other archaeologically related vessels show a different chemical pattern of unknown provenance. (author)

    The depletion of fossil fuels and hike in crude oil prices were some of the main reasons to explore new alternatives from renewable source of energy. This work presents the impact of various bowl geometries on diesel engine with diesel and biodiesel samples. Three non-edible oils were selected, namely pumpkin seed oil, orange oil and neem oil. These oils were converted into respective biodiesel using transesterification process in the presence of catalyst and alcohol. After transesterification process, the oils were termed as pumpkin seed oil methyl ester (PSOME), orange oil methyl ester (OME) and neem oil methyl ester (NOME), respectively. The engine used for experimentation was a single-cylinder four-stroke water-cooled direct-injection diesel engine and loads were applied to the engine using eddy current dynamometer. Two bowl geometries were developed, namely toroidal combustion chamber (TCC) and trapezoidal combustion chamber (TRCC). Also, the engine was inbuilt with hemispherical combustion chamber (HCC). The base line readings were recorded using neat diesel fuel with HCC for various loads. Followed by 20% of biodiesel mixed with 80% neat diesel for all prepared methyl esters and termed as B1 (20% PSOME with 80% diesel), B2 (20% OME with 80% diesel) and B3 (20% NOME with 80% diesel). All fuel samples were tested in HCC, TCC and TRCC bowl geometries under standard injection timing and with compression ratio of 18. Increased brake thermal efficiency and reduced brake specific fuel consumption were observed with diesel in TCC geometry. Also, higher heat release and cylinder pressures with lower ignition delay were recorded with TCC bowl geometry. TCC bowl geometry showed lower CO, HC and smoke emissions with B2 fuel sample than diesel and other biodiesel samples. But, higher NOx emission was observed in HCC and TCC than that in TRCC bowl geometry. Graphical abstract ᅟ.

    Abstract Background Previous studies have reported that the design of the water dispensers can influence the water intake in farm animals. Horses and dairy cows seem to prefer to drink from an open surface whereas sheep and pigs apparently prefer water nipples, probably because of the worse water quality in water bowls. The aim of the present study was to examine the preference of dairy goats for water nipples or water bowls. Methods In each of the two experiments (exp. 1, dry goats, exp. 2 l...

  14. Becoming a Hidden Champion: From Selective use of Customer Intimacy and Product Leadership to Business Attractiveness

    Directory of Open Access Journals (Sweden)

    2017-04-01

    Full Text Available This paper sheds light on factors that support SMEs becoming market leaders on an international scale. Specifically, it studies the hidden champion type of companies, defined as SMEs that hold market leadership in narrow business segments on a regional or wider international scale. The market positioning of hidden champions is defined subjectively by CEOs in such a way that they create a high level of business attractiveness. This explorative study reveals that product leadership and customer intimacy are two blocks that build the business attractiveness of hidden champions. More specifically, the study on data from 93 niche leaders from Central and Eastern Europe showed that product leadership negatively moderates the business attractiveness-performance relationship, while the impact of the combination of product leadership and customer intimacy on the business attractiveness-firm performance relationship is not straightforward and depends on different combinations of these values.

    Beach, Aaron J; Ferdinands, René E D; Sinclair, Peter J

    2016-09-01

    Spin bowling is generally coached using a standard technical framework, but this practice has not been based upon a comparative biomechanical analysis of leg-spin and off-spin bowling. This study analysed the three-dimensional (3D) kinematics of 23 off-spin and 20 leg-spin bowlers using a Cortex motion analysis system to identify how aspects of the respective techniques differed. A multivariate ANOVA found that certain data tended to validate some of the stated differences in the coaching literature. Off-spin bowlers had a significantly shorter stride length (p = 0.006) and spin rate (p = 0.001), but a greater release height than leg-spinners (p = 0.007). In addition, a number of other kinematic differences were identified that were not previously documented in coaching literature. These included a larger rear knee flexion (p = 0.007), faster approach speed (p < 0.001), and flexing elbow action during the arm acceleration compared with an extension action used by most of the off-spin bowlers. Off-spin and leg-spin bowlers also deviated from the standard coaching model for the shoulder alignment, front knee angle at release, and forearm mechanics. This study suggests that off-spin and leg-spin are distinct bowling techniques, supporting the development of two different coaching models in spin bowling.

    The Nintendo Wii is a gaming console with motion-sensitive controls that is making inroads into health care and rehabilitation. However, there is still limited knowledge on how elderly people perceive the use of such a product. The aim of this study was to examine how the use of the Wii Sports Bowling in an activity group was perceived by elderly people. The data consisted of observations and interviews with participants who used Wii Sports Bowling and was analysed with content analysis. The findings are described in three themes; 'The use of the Wii Sports game', 'Engagement in the game' and 'Social interaction around the activity'. Wii Sports Bowling was described as easier to play compared to real-life bowling and was enjoyable and a social activity. The opportunity to meet the group each week was important for the participants. Playing the game resulted in signs of immersion and a flow-like state. The Wii was perceived to be easy to use, to provide a way to socialize with peers and to give opportunities to participate in activities in a new way. More studies regarding elderly people's experiences and apprehensions regarding new technology such as gaming consoles and virtual reality are needed.

  5. Phreatic explosions during basaltic fissure eruptions: Kings Bowl lava field, Snake River Plain, USA

    Physical and compositional measurements are made at the 7 km-long ( 2200 years B.P.) Kings Bowl basaltic fissure system and surrounding lava field in order to further understand the interaction of fissure-fed lavas with phreatic explosive events. These assessments are intended to elucidate the cause and potential for hazards associated with phreatic phases that occur during basaltic fissure eruptions. In the present paper we focus on a general understanding of the geological history of the site. We utilize geospatial analysis of lava surfaces, lithologic and geochemical signatures of lava flows and explosively ejected blocks, and surveys via ground observation and remote sensing. Lithologic and geochemical signatures readily distinguish between Kings Bowl and underlying pre-Kings Bowl lava flows, both of which comprise phreatic ejecta from the Kings Bowl fissure. These basalt types, as well as neighboring lava flows from the contemporaneous Wapi lava field and the older Inferno Chasm vent and outflow channel, fall compositionally within the framework of eastern Snake River Plain olivine tholeiites. Total volume of lava in the Kings Bowl field is estimated to be 0.0125 km3, compared to a previous estimate of 0.005 km3. The main (central) lava lake lost a total of 0.0018 km3 of magma by either drain-back into the fissure system or breakout flows from breached levees. Phreatic explosions along the Kings Bowl fissure system occurred after magma supply was cut off, leading to fissure evacuation, and were triggered by magma withdrawal. The fissure system produced multiple phreatic explosions and the main pit is accompanied by others that occur as subordinate pits and linear blast corridors along the fissure. The drop in magma supply and the concomitant influx of groundwater were necessary processes that led to the formation of Kings Bowl and other pits along the fissure. A conceptual model is presented that has relevance to the broader range of low-volume, monogenetic

    Bibliometric analysis was carried out for champion data comparisons among prestigious nuclear research institutes (PNRI) existed in Japan, the U. S., France, and Germany. The analysis was relied on database INIS (IAEA), ECD (DOE), WOS (Thomson), and SCOPUS (Elsevier). INIS is advanced, key ex-post evaluating tool for determining general research paper-based champion. Over the 30-year time span of research paper publication, the world champion among 11 PNRI is JAERI confirmed by INIS but ORNL confirmed by ECD, WOS, and SCOPUS, the latter two collected journal submitted research paper. Five years ago JAERI is the 3rd ranked institutes following ORNL and ANL. INIS database results revealed that CEA/Grenoble is the French domestic champion regarding research paper publication. Five years ago it was CEA/Saclay. Results from analytical tools used in bibliometric studies should be viewed with careful consideration to learn of any influencing factors because different characteristics exhibited by individual databases can sometimes generate conflicting bibliometric results. This was true among INIS, ECD, WOS, and SCOPUS when looking at trends especially between 5-year periods. (author)

    2014-09-01

    This paper examines the value of participatory approaches within interventions aimed at promoting mental health and wellbeing in the workplace. Specifically the paper explores data from the thematic evaluation of the Mental Health and Employment project strand within the Altogether Better programme being implemented in England in the Yorkshire and Humber region, which was funded through the BIG Lottery and aimed to empower people across the region to lead better lives. The evaluation combined a systematic evidence review with semi-structured interviews across mental health and employment projects. Drawing on both evaluation elements, the paper examines the potential of workplace-based 'business champions' to facilitate organizational culture change within enterprises within a deprived regional socio-economic environment. First, the paper identifies key policy drivers for interventions around mental health and employment, summarizes evidence review findings and describes the range of activities within three projects. The role of the 'business champion' emerged as crucial to these interventions and therefore, secondly, the paper examines how champions' potential to make a difference depends on the work settings and their existing roles, skills and motivation. In particular, champions can proactively coordinate project strands, embed the project, encourage participation, raise awareness, encourage changes to work procedures and strengthen networks and partnerships. The paper explores how these processes can facilitate changes in organizational culture. Challenges of implementation are identified, including achieving leverage with senior management, handover of ownership to fellow employees, assessing impact and sustainability. Finally, implications for policy and practice are discussed, and conclusions drawn concerning the roles of champions within different workplace environments. © The Author (2013).

    Full Text Available Equines morphometric analysis is an important method of selection related to functionality of the species. Mangalarga Marchador is the most important horse Brazilian breed and its evolution can be observed in specialized exhibition where owners expase their herd with the breed exponents, adopting them as selection parameters. In this context the study aimed to compare the morphometric measures of Mangalarga Marchador males herd with the champions of breed, using as parameters breed standards and Eclectic System of Proportions for saddle horse. Experimental design was completely randomized and treatments were the Mangalarga Marchador male herd, represented by all horses registered from 2000 to 2012, wich had measurements stored in Associação Brasileira de Criadores do Cavalo Mangalarga Marchador (ABCCMM service studbook database, totaling 15,482 animals, and the champions of breed, represented by 222 horses champions who participated of the 29th, 30th or 31th Exposição Nacional do Cavalo Mangalarga Marchador. Variables evaluated were height at withers and at rump, length of the head, neck, dorse, rump, shoulder and body, width of head and of rump, thoracic perimeter and cannon perimeter. Average linear measurements were related to length of head, according to Eclectic System of Proportions for saddle horse. Results were submitted to variance analysis and averages were compared by Fisher test (p<0.05. Regarding the current herd of males Mangalarga Marchador, the champions of the race showed greater length of neck, dorse, rump and body, height at withers and at rump, width of rump, cannon perimeter and shorter length of the shoulder. It was concluded that although larger, the champions horses Mangalarga Marchador are proportionally similar to current herd. Mangalarga Marchador horses have not yet reached the height considered ideal by breed standard and their proportions are different from those recommended by Eclectic System of Proportions for

    Full Text Available BackgroundTo construct a sophisticated three-dimensional framework, numerous modifications have been reported in the literature. However, most surgeons have paid little attention to the anatomical configuration of the concha and more to its deepness and hollowness, leading to unsatisfactory outcomes.MethodsFor a configuration of the concha that is definitely anatomical, the author further developed and employed the conchal bowl element, which has been used by several surgeons although the results have not been published elsewhere. The author constructed the conchal bowl element in one of three patterns according to the amount of available cartilages: one block, two-pieces, or a cymba bowl element only. A total of 20 patients underwent auricular reconstruction using a costal cartilage framework between 2009 and 2012. The 8 earliest reconstructions were performed without a conchal bowl element and the latter 12 with a conchal bowl element. The patients were followed up for more than 1 year. The aesthetic results were scored by evaluating characteristics involving the stability of the crus helicis, the conchal definition, and the smoothness of the helical curve.ResultsThe ears reconstructed early without a conchal bowl element showed a shallow and one or two incompletely separated concha with an obliterated cymba conchal space. They also did not have a realistic or smooth curve of the helix because of an unstable crus helicis. However, ears reconstructed later with the concha bowl element showed a definite crus helicis, deep cymba conchal space, and smooth helical curve.ConclusionsThe construction of the conchal bowl element is simple, not time-consuming procedure. It is suggested that the conchal bowl element must be constructed and attached to the main framework for natural configuration of the reconstructed ear.

    Improving care quality while reducing cost has always been a focus of nursing homes. Certified nursing assistants comprise the largest proportion of the workforce in nursing homes and have the potential to contribute to the quality of care provided. Quality improvement (QI) initiatives using certified nursing assistants as champions have the potential to improve job satisfaction, which has been associated with care quality. To identify the role, use and preparation of champions in a nursing home setting as a way of informing future QI strategies in nursing homes. A systematic literature review. Medical Subject Headings and text words for "quality improvement" were combined with those for "champion*" to search Medline, CINAHL, Joanna Briggs Institute, MedLine In-Process, and other Nonindexed Citations. After duplicates were removed, a total of 337 potential articles were identified for further review. After full text review, seven articles from five original studies met inclusion criteria and were included in the synthesis. Various types of QI initiatives and implementation strategies were used together with champions. Champions were identified by study authors as one of the single most effective strategies employed in all studies. The majority of studies described the champion role as that of a leader, who fosters and reinforces changes for improvement. Although all the included studies suggested that implementing nurse or aid champions in their QI initiatives were important facilitators of success, how the champions were selected and trained in their role is either missing or not described in any detail in the studies included in the review. Utilizing certified nursing assistants as QI champions can increase participation in QI projects and has the potential to improve job satisfaction and contribute to improve quality of care and improved patient outcomes in nursing homes. © 2017 Sigma Theta Tau International.

    King's Bowl (KB), located in Idaho's eastern Snake River Plain, was formed by a phreatic blast through a mostly-congealed lava lake. Blocks up to ~2m diameter were ejected from the vent to form a ballistic ejecta blanket extending radially more than 100m. The blocks on the western side of the KB fissure are extraordinarily well exposed, as the fine fraction was blown eastward by ambient winds during the explosion. We present preliminary modeling results using the western ballistic blocks of KB to calculate the energy of the eruption, and the water volume necessary to create the blast. This work is presented in conjunction with two other 2014 AGU conference abstracts submitted by NASA SSERVI funded FINESSE (Field Investigations to Enable Solar System Science and Exploration) team members: Hughes et al., which introduces the geology of KB and Sears et al., which discusses field observation and data trends. Results of this research are extensible to steam-driven pits on other solar system bodies, including those observed on Mars, Phobos, Deimos, and the asteroids. Over 600 blocks ranging from .2 to 2m in diameter were mapped using differential GPS and measured for 3 axial lengths and vesicularity. Mass calculations were corrected using a scaling factor determined from measurements of 100 blocks at KB, coupled with targeted density measurements. The dispersed block trajectories were modeled using a fourth order Runge-Kutta solution of the equations of motion to calculate suites of possible ejection speeds and angles. The resulting characteristic vent velocities were used to calculate the kinetic energy necessary to evacuate the crater at KB; energy required for fragmentation is neglected at this time. Total mass in the kinetic energy calculations was calculated by two separate methods: 1) current volume expression of the KB crater and 2) an additive solution of the ejecta field as determined from radial transect surveys. From the kinetic energy we calculated the

    2018-03-01

    Due to the high incidence of lumbar spine injury in fast bowlers, international cricket organisations advocate limits on workload for bowlers under 19 years of age in training/matches. The purpose of this study was to determine whether significant changes in either fast bowling technique or movement variability could be detected throughout a 10-over bowling spell that exceeded the recommended limit. Twenty-five junior male fast bowlers bowled at competition pace while three-dimensional kinematic and kinetic data were collected for the leading leg, trunk and bowling arm. Separate analyses for the mean and within-participant standard deviation of each variable were performed using repeated measures factorial analyses of variance and computation of effect sizes. No substantial changes were observed in mean values or variability of any kinematic, kinetic or performance variables, which instead revealed a high degree of consistency in kinematic and kinetic patterns. Therefore, the suggestion that exceeding the workload limit per spell causes technique- and loading-related changes associated with lumbar injury risk is not valid and cannot be used to justify the restriction of bowling workload. For injury prevention, the focus instead should be on the long-term effect of repeated spells and on the fast bowling technique itself.

    2017-11-01

    Health experts and communication experts assert that the media influence individuals' health. Yet, incongruously, the public, policy-makers and the media themselves appear reticent to accept that the media could have extensive negative influence on health. The current study examined all ads that aired from Super Bowl XLVI through Super Bowl XLIX (N = 241) using a detailed, multistep coding process. Ads had similar racial/ethnic diversity in the full sample and food/beverage ads. A minority (14.5%) of advertisements contained actors with overweight/obesity, who were more likely to be White and less likely to be Hispanic compared with race/ethnicity in all ads. Humour and tone were similarly present whether or not the ads included actors with overweight/obesity. Findings are striking given the high prevalence of overweight/obesity in the USA, particularly among Black and Hispanic populations, and the comparatively low representation of actors with overweight/obesity in Super Bowl advertisements. Surprising weight findings may signal a change in how the media portray body-size norms (away from exclusively thin), although representations remain disproportionate from actual body-size distributions in the USA. © 2017 John Wiley & Sons Ltd.

    2016-05-01

    Peer health champions have been suggested as an important component of multilevel workplace interventions to promote healthy behaviours such as physical activity (PA). There is accumulating quantitative evidence of their effectiveness but as yet little exploration of why and how champions influence peer behaviour. The current study explores the role of peer physical activity champions (PPACs) in influencing colleagues' PA behaviour from the perspectives of both champions and colleagues. Seven months after the introduction of a workplace PA programme in 17 small- and medium-sized enterprises (SMEs), two focus groups were held with PPACs and four with programme participants. Data were analysed using inductive thematic analysis. Three overarching themes were developed: how PPACs encourage PA, valuable PPAC characteristics and sustaining motivation for the PPAC role. Both direct encouragement from PPACs and facilitation of wider PA supportive social networks within the workplace encouraged behaviour change. PA behaviour change is a delicate subject and it was important that PPACs provided enthusiastic and persistent encouragement without seeming judgemental. Being a PA role model was also a valuable characteristic. The PPACs found it satisfying to see positive changes in their colleagues who had become more active. However, colleagues often did not engage in suggested activities and PPACs required resilience to maintain personal motivation for the role despite this. Incorporating PPACs into SME-based PA interventions is acceptable to employees. It is recommended that PPAC training includes suggestions for facilitating social connections between colleagues. Sensitivity is required when initiating and engaging in conversations with colleagues about increasing their PA. Programmes should ensure PPACs themselves are provided with social support, especially from others in the same role, to help sustain motivation for their role. These findings will be useful to health

    A campus-community partnership can be an effective vehicle for launching environmental strategies to prevent college alcohol-related problems. In this study, the authors' primary aim was identifying key factors that facilitate or impede colleges' efforts to build campus-community partnerships. From fall 2004 to summer 2006, administrators at five 4-year colleges participated in a multisite case study. Level of partnership development was the primary outcome. Three interrelated factors facilitated higher-developed partnerships: college staff assigned to facilitate the partnerships who worked as community organizers, higher-level college administrators who served as aggressive champions, and community initiation of the partnership. The authors did not observe this trio of factors among the less-developed partnerships. A lack of administrative support made it more difficult for a champion to emerge, a college administrator who staunchly advocated for a campus-community partnership, and for those assigned to facilitate the partnership to carry out their work. Colleges should appoint higher-level administrators to serve as champions, while also ensuring that those assigned to facilitate a partnership can apply community organizing skills.

    Full Text Available Background  To construct a sophisticated three-dimensionalframework, numerousmodifications have been reported in the literature. However, mostsurgeons have paid little attentionto the anatomical configuration of the concha and more to its deepness and hollowness,leading to unsatisfactory outcomes.Methods  For a configuration ofthe concha thatis definitely anatomical,the authorfurtherdeveloped and employed the conchal bowl element,which has been used by severalsurgeonsalthough the results have not been published elsewhere. The author constructed the conchalbowl element in one of three patterns according to the amount of available cartilages: oneblock,two-pieces, or a cymba bowl element only. A total of 20 patients underwent auricularreconstruction using a costal cartilage framework between 2009 and 2012. The 8 earliestreconstructionswere performedwithout a conchal bowl element and the latter 12with a conchalbowl element. The patientswere followed up for more than 1 year. The aesthetic resultswerescored by evaluating characteristicsinvolving the stability ofthe crus helicis,the conchal definition, and the smoothness ofthe helical curve.Results  The earsreconstructed earlywithout a conchal bowl elementshowed a shallowandone or two incompletely separated concha with an obliterated cymba conchal space. Theyalso did not have a realistic orsmooth curve ofthe helix because of an unstable crus helicis.However, earsreconstructed laterwith the concha bowl elementshowed a definite crus helicis,deep cymba conchalspace, and smooth helical curve.Conclusions  The construction of the conchal bowl element is simple, not time-consumingprocedure. It is suggested that the conchal bowl element must be constructed and attachedto themain framework for natural configuration ofthe reconstructed ear.

  8. "Hot hand" on strike: bowling data indicates correlation to recent past results, not causality.

    Directory of Open Access Journals (Sweden)

    Gur Yaari

    Full Text Available Recently, the "hot hand" phenomenon regained interest due to the availability and accessibility of large scale data sets from the world of sports. In support of common wisdom and in contrast to the original conclusions of the seminal paper about this phenomenon by Gilovich, Vallone and Tversky in 1985, solid evidences were supplied in favor of the existence of this phenomenon in different kinds of data. This came after almost three decades of ongoing debates whether the "hot hand" phenomenon in sport is real or just a mis-perception of human subjects of completely random patterns present in reality. However, although this phenomenon was shown to exist in different sports data including basketball free throws and bowling strike rates, a somehow deeper question remained unanswered: are these non random patterns results of causal, short term, feedback mechanisms or simply time fluctuations of athletes performance. In this paper, we analyze large amounts of data from the Professional Bowling Association(PBA. We studied the results of the top 100 players in terms of the number of available records (summed into more than 450,000 frames. By using permutation approach and dividing the analysis into different aggregation levels we were able to supply evidence for the existence of the "hot hand" phenomenon in the data, in agreement with previous studies. Moreover, by using this approach, we were able to demonstrate that there are, indeed, significant fluctuations from game to game for the same player but there is no clustering of successes (strikes and failures (non strikes within each game. Thus we were lead to the conclusion that bowling results show correlation to recent past results but they are not influenced by them in a causal manner.

    Using a model system, a concept for the immobilization of microbial cultures within alginate beads directly in a 1500-L fermentor with a height to diameter ratio of 1.85 is described. The system is comprised of a 60-cm diameter bowl fixed to the top of an agitation shaft, where calcium-ion-rich media is continuously recirculated from the bulk solution to the bowl. The rotation of the shaft and bowl creates a climbing film (vortex) of solution. An atomizing disk centrally recessed within the bowl sprays an alginate solution into the climbing film where the droplets harden into beads. The effect of heat treatment on the alginate solution on resulting bead properties was examined. The sterilization operation did not appear to have a major effect on the alginate bead mechanical properties of firmness and elasticity which was much more a function of alginate concentration. Beads of various sizes were produced by the unit. The system was characterized by the dimensionless numbers Reomega = (omega x rho x D(2))/mu and ReQ = (Q x rho)/(mu x D). At Reomega and ReQ values less than 500 and 0.15, respectively, the mechanism was direct drop. Parent droplets followed by satellite droplets were observed. When either the flow rate or speed was increased, filaments formed predominantly, which was unwanted in this system because filament breakdown into smaller droplets does not occur due to the proximity of the disk to the climbing film in the bowl. This system could be applied to the immobilization of microorganisms, as well as plant or animal cell cultures, and for other sizes or fermentors. The overflow from the bowl carries the gellified beads into the bulk solution where immobilized cells could act upon the fermentation media. Copyright 2000 John Wiley & Sons, Inc.

    Leading radiologists and representatives from national radiation protection regulatory authorities and health ministries from 19 countries of the European region worked together with five experts at the workshop on justification and appropriate use of imaging in Zagreb, Croatia, from 26 to 28 October 2017 jointly organised by the IAEA and the European Society of Radiology. The workshop served as a forum to exchange information on challenges and solutions for improving justification and the appropriate use of diagnostic imaging. Common barriers to improving the use of imaging referral guidelines were discussed and the need for increased collaboration identified. Examples of good practices were presented, including use of Clinical Decision Support (CDS) systems to facilitate rapid and good justification decisions. The workshop identified some of the needs of European countries for achieving more appropriate imaging proposing wider use of collaboration, campaigns and champions. • Drivers for appropriate imaging in Europe are similar to those elsewhere globally. • Implementing imaging referral guidelines is the main barrier to more appropriate imaging. • Clinical Decision Support systems (CDS) facilitates good referral practice and justification decisions. • Collaboration, campaigns and champions may improve awareness, appropriateness and audit.

    Background: The National Football League (NFL) Super Bowl is a widely-viewed sports event and the commercials are especially popular among viewers. Previous research has demonstrated risky health behaviors in advertisements aired during sporting events. The purpose of this study was to analyze the content of the advertisements aired during the 2017 NFL Super Bowl. Methods: This cross-sectional study involved examining the content of all commercials, with an emphasis on health-compromising behaviors. The themes and highlights of the advertisements were analyzed based on whether there was a reference to alcohol or violence. Results: A total of 103 unique commercials were analyzed. The most common themes were humor (n=43), happiness (n=25), innovation (n=25), and enjoyment or relaxation (n=25).Alcohol was referenced in 13 (12.6%, 95% CI 7.5%, 20.4%) of the commercials. Advertisements with alcohol references were more likely to contain the themes of partying (odds ratio [OR]:16.2, 95% CI 1.4-193.4, P=0.041) and enjoyment or relaxation (OR: 4.7, 95% CI 1.4-15.6,P=0.014).

    The few studies dealing with the positive effects of health and well-being of older people are only one-sided. The aim of the study therefore was to analyze the effects of Nintendo-Wii® bowling on daily function, state of dementia, quality of life, cognition and motor skills in retirement home inhabitants. The study was performed with 27 study participants (13 women, 14 men) between the ages of 49 and 95 years (mean = 71, SD = 14). They were randomly assigned to a control group (KG) and an intervention group (IG). Between pre- and posttest, the IG played 60 min/twice a week Nintendo-Wii® Bowling over 6 weeks. The improvement of IG was significant in the analysis of variance concerning strength (arm curls: F df = 2 = 7.199; p = 0,013; η(2) = 0,231) and showed a significant trend concerning coordination (tracking lines: F df = 2 = 3.99; p = 0,058; η(2) = 0,154) compared with KG. The area of rapidity (catching bars: F df = 2 = 28.511; p = 0,008; η(2) = 0,279) showed a significant decline in the IG compared with the KG. However, closer examination shows that the short time of intervention and the wide age range could have affected the results. Thus, further studies should take these critical aspects into consideration.

    A novel combined seed mediated and galvanic replacement method has been demonstrated to synthesize a new class of trimetallic PtAuAg nanocatalysts with highly open bowl-like nanocage structure. The newly-generated PtAuAg nanocages catalysts exhibit superior electrocatalytic performances towards ethylene glycol oxidation with the mass activity of 6357.1 mA mg-1, 5.5 times higher than that of commercial Pt/C (1151.1 mA mg-1). This work demonstrates the first example of designing shape-controlled architectures of trimetallic bowl-like PtAuAg nanocages for liquid fuel electrooxidation.

    A champion in health care can be defined as any health professional who has the requisite knowledge and skills in a relevant health field, who is respected by his/her peers and supported by his/her supervisors, and who takes the lead to promote or introduce evidence-based interventions to improve the quality of care. Jhpiego used a common approach during two distinct initiatives to identify individuals in Africa, Asia, and Latin America and the Caribbean whose expertise in their clinical service area and whose leadership capacity could be strengthened to enable them to serve as champions for maternal and newborn health (MNH). These champions have gone on to contribute to the improvement of MNH in their respective countries and regions. The lessons learned from this approach are shared so they can be used by other organizations to design leadership development strategies for MNH in low-resource countries. Copyright © 2015.

  20. The effect of spin in swing bowling in cricket: model trajectories for spin alone

    Science.gov (United States)

    Robinson, Garry; Robinson, Ian

    2015-02-01

    In ‘swing’ bowling, as employed by fast and fast-medium bowlers in cricket, back-spin along the line of the seam is normally applied in order to keep the seam vertical and to provide stability against ‘wobble’ of the seam. Whilst spin is normally thought of as primarily being the slow bowler's domain, the spin applied by the swing bowler has the side-effect of generating a lift or Magnus force. This force, depending on the orientation of the seam and hence that of the back-spin, can have a side-ways component as well as the expected vertical ‘lift’ component. The effect of the spin itself, in influencing the trajectory of the fast bowler's delivery, is normally not considered, presumably being thought of as negligible. The purpose of this paper is to investigate, using calculated model trajectories, the amount of side-ways movement due to the spin and to see how this predicted movement compares with the total observed side-ways movement. The size of the vertical lift component is also estimated. It is found that, although the spin is an essential part of the successful swing bowler's delivery, the amount of side-ways movement due to the spin itself amounts to a few centimetres or so, and is therefore small, but perhaps not negligible, compared to the total amount of side-ways movement observed. The spin does, however, provide a considerable amount of lift compared to the equivalent delivery bowled without spin, altering the point of pitching by up to 3 m, a very large amount indeed. Thus, for example, bowling a ball with the seam pointing directly down the pitch and not designed to swing side-ways at all, but with the amount of back-spin varied, could provide a very powerful additional weapon in the fast bowler's arsenal. So-called ‘sling bowlers’, who use a very low arm action, can take advantage of spin since effectively they can apply side-spin to the ball, giving rise to a large side-ways movement, ˜ 20{}^\\circ cm or more, which certainly is

    This article offers an analysis of the present competitive and regulatory framework of the European electricity sector. Considering the complexity of this industry, the focus in this work is mainly on the problem of market concentration of incumbents in the sector as a result of the liberalisation process. The new trend toward the creation of ''national champions'' as well as recent mergers between gas suppliers and electricity producers raised serious concerns about abuses of market power and risks of future collusion. Taking account of investment in interconnection as well as other international and regional experiences, the internal market issue is investigated as the solution to the''risks'' from liberalisation.

    At the heart of recovery-oriented psychiatric mental health care are the dignity and respect of each person and the ways in which helping professionals convey a person's uniqueness, strengths, abilities, and needs. "Person-first language" is a form of linguistic expression relying on words that reflect awareness, a sense of dignity, and positive attitudes about people with disabilities. As such, person-first language places emphasis on the person first rather than the disability (e.g., "person with schizophrenia" rather than "a schizophrenic"). This article champions the use of person-first language as a foundation for recovery-oriented practice and enhanced collaborative treatment environments that foster respect, human dignity, and hope.

    Full Text Available According to precise and scientific literature that recorded, Chinese tea culture has a documented history of more than 1700 years. During which period, Yuan Dynasty was considered a crucial turning-point with great changes. The current tea culture in China is an adoption and innovation of Ming and Qing dynasty, especially in the form of processing technology. For those elements inherited from Tang and Song dynasties, however, they were more directly adopted systematically by Japan. Ever since powdered tea culture from Song dynasty was accepted in Japan, Jianzhan, the tea bowl that gained renowned reputation in the Song tea culture was also introduced and became tenmoku (tianmu after localization. As the transformation of Chinese tea culture ended in Japan, Japanese tea culture of wabi-cha was shaped after the tenmoku’s obvious decline in value.

    Lee, J. A.

    2017-12-01

    This paper deals with the role of wind erosion and blowing dust on the music of the Dust Bowl region, a portion of the southern Great Plains of the United States. A defining characteristic of the region is dust storms, and in the 1930s, severe dust storms created dramatic images that came to symbolize all of the economic, social and environmental hardships suffered by the people during the 1930s. The music of the time, by Woody Guthrie and others, suggested that the region was being destroyed, never to recover. The region was resilient, however, and in recent decades, dust has been depicted in songs either as an adversity to be endured or simply as a normal part of life in the area. It may be that blowing dust has become a defining characteristic of the region because of a somewhat warped sense of pride in living in an often-difficult environment.

    Full Text Available The area of tactics in soccer game is of particular importance for modern soccer development. The analysis and improvement of spatio-temporal indicators as well as the game principles related to tactics may be crucial to the achievement of competitive results. This study is aimed at comparing tactical manifestations of the teams competing in the top quality European club competition, the Champions League, and the best Serbian soccer championship by analyzing competitive activity. The results of the conducted research were obtained by observing an overall of 20 randomly selected matches, 10 of the Champions League (CL and 10 of the Serbian Super Liga (SSL, which is a sufficient number of matches for making conclusions about the competitions respectively. In the previously designed observing protocol, using a method of notation, we analyzed all the attacks completed by shooting at the opponent's goal. The structure of successfully realized attacks was assessed on the basis of: accuracy, types of realized offensive actions; area of starting the action, manner of realization of passes completed (assists and distance from the goal from which a shot on goal was executed. The study showed that there are certain common characteristics, but also there are differences in the structure of successfully realized attacks between the two analyzed competitions. The teams of the CL competition had significantly greater number of effective attacks per match (p = 0. 006, they realized their offensive activities with slightly greater number of players (p = 0.002 and number of passes (p = 0.000, whereas there are no significant differences in the area of starting successful attacks, the manner of realization of assists and distance from which shots on goal were executed. The study results may define certain guidelines in training technology when preparing the teams of the SSL competition for taking part in the European soccer cups.

  11. The Byzantine Silver Bowls in the Sutton Hoo Ship Burial and Tree-Worship in Anglo-Saxon England

    Michael D. J. Bintley

    2011-12-01

    Full Text Available The ten Byzantine silver bowls included amongst the grave goods interred in the chamber of the Mound 1 ship burial at Sutton Hoo remain one of the most puzzling features of this site. It has been suggested that these items, which lay separated from the rest of the silver in the burial and close to the head of the body-space (where no body was found, may have had some special meaning which has never been discovered. This paper will argue that one of the possible keys to unlocking their significance may be found in the central roundel that adorns the centre of each bowl in the form of a rosette. These bowls, which are thought to have been manufactured in the eastern provinces of the Byzantine Empire in c. 600, entered the British Isles in unknown circumstances before coming into the possession of the man buried in (or commemorated by the Mound 1 burial. Through comparison with contemporary sculpture and vernacular literature, I will suggest that this central rosette, which was associated with both the cross of Christ and sacred trees in Byzantine sculpture, may have served as a conventional bridge between Christian and pre-Christian religious traditions associated with sacred trees in Anglo-Saxon England. The central rosettes adorning each of these bowls may have been understood as the flower of a sacred tree. Since the latter appears to have figured in Anglian paganism it is possible that the bowls may helped to convert the Anglian aristocracy, bridging a gap between Germanic insular religious traditions and those that were being introduced to Britain at the time that the ship burial itself took place.

    Record-breaking summer heat waves that plagued contiguous United States in the 1930s emerged during the decade-long "Dust Bowl" drought. Using high-quality daily temperature observations, the Dust Bowl heat wave characteristics for the Great Plains are assessed using metrics that describe variations in heat wave activity and intensity. We also quantify record-breaking heat waves over the pre-industrial period for 22 CMIP5 model multi-century realisations. The most extreme Great Plains heat wave summers in the Dust Bowl decade (e.g. 1931, 1934, 1936) were pre-conditioned by anomalously dry springs, as measured by proxy drought indices. In general, summer heat waves over the Great Plains develop 15-20 days earlier after anomalously dry springs, and are also significantly longer and hotter, indicative of the importance of land surface feedbacks in heat wave intensification. The majority of pre-industrial climate model experiments capture regionally clustered summer heat waves across North America, although the North Pacific and Atlantic sea surface temperature patterns associated with the heat waves vary considerably between models. Sea surface temperature patterns may be more important for influencing winter and spring precipitation, thus amplifying summer heat waves during drought periods. The synoptic pattern that commonly appeared during the exceptional Dust Bowl heat waves featured an anomalous broad surface pressure ridge straddling an upper level blocking anticyclone over the western United States. This forced significant subsidence and adiabatic warming over the Great Plains, and triggered anomalous southward warm advection over southern regions, prolonging and amplifying the heat waves over central United States. Importantly, the results show that despite the sparsity of stations in the 1930s, homogeneous observations are crucial in accurately quantifying the Dust Bowl decade heat waves, as opposed to solely relying on atmospheric reanalysis.

    Kings Bowl is a ~2200ka pit crater created by a phreatic blast along a volcanic fissure in the eastern Snake River Plain (ESRP), Idaho. The main crater measures approximately 80m in length, 30m in width, and 30m in depth, with smaller pits located nearby on the Great Rift fissure, and has been targeted by the FINESSE team as a possible analogue for Cyane Fossae, Mars. The phreatic eruption is believed to have occurred due to the interaction of groundwater with lava draining back into the fissure following a lava lake high stand, erupting already solidified basalt from this and previous ERSP lava flows. The contemporaneous draw back of the lava with the explosions may conceal some smaller possible blast pits as more lava drained into the newly formed pits. Ballistic ejecta from the blasts occur on both sides of the fissure. To the east, the ballistic blocks are mantled by fine tephra mixed with eolian dust, the result of a westerly wind during the explosions. We use differential GPS to map the distribution of ballistic blocks on the west side of the fissure, recording position, percent vesiculation, and the length of 3 mutually perpendicular axes for each block >20cm along multiple transects parallel to the fissure. From the several hundred blocks recorded, we have been able to separate the ballistic field into several distinct blast deposits on the basis of size distributions and block concentration. The smaller pits identified from the ballistic fields correspond broadly to the northern and southern limits of the tephra/dust field east of the fissure. Soil formation and bioturbation of the tephra by sagebrush have obliterated any tephrostratigraphy that could have been linked to individual blasts. The ballistic block patterns at Kings Bowl may be used to identify distinct ejecta groups in high-resolution imagery of Mars or other planetary bodies.

    Highlights: • A novel biofuel, Cymbopogon flexuosus is used as an alternative energy source. • C20-D80 + 20 ppm profile stayed close to diesel fuel with BB. • Three different combustion bowl CB1, CB2, and CB3 were considered. • Resulting in higher thermal efficiency and lower HC, CO, emission. • Reduction of oxides of nitrogen and smoke emission for C20-D80 + 20 ppm and CB2. - Abstract: The aim of this experimental work is to figure out the optimized the combustion bowl geometry on a constant speed diesel engine for its efficient functioning with a novel biofuel. The novel biofuel considered for this research work was Cymbopogon flexuosus biofuel. To improve the performance level, 20% Cymbopogon flexuosus biofuel was blended with 80% of diesel fuel (C20-D80) and to further reduce the emission magnitude, 20 ppm of cerium oxide was added to the blended fuel (C20-D80 + 20 ppm). For this study four different combustion bowls were designed based on the keen literature survey. They were hemispherical combustion bowl (BB), shallow depth re-entrant combustion bowl (CB1), Toroidal re-entrant combustion bowl (CB2), Toroidal combustion bowl (CB3). Based on the experimental evaluation, the results have been discussed for low load and full load conditions for better understanding. Regarding the fuel modification, C20-D80 + 20 ppm resulted in better engine characteristics owing to combined effect of the oxygen molecule bearing fuel and superior thermal stability and activation energy of the cerium oxide nanoparticle. Of the various bowls considered for the tests, the combustion bowl CB2 showed superior performance and emission reduction compared with its competitors CB1, CB2, and BB. It could have ascribed to the better mixing rate, gain of swirl velocity and the turbulence level of the bowl. CB2 resulted in higher BTE and lower BSEC of 4.1% and 12.02% in low and full load conditions for C20-D80 + 20 ppm. Emission reduction observed was 17% of HC, 43.66% of CO and

    To evaluate the sanitary conditions of toilets, the bacterial counts of the toilet bowl biofilms in 5 Kansai area and 11 Kansai and Kanto area homes in Japan were measured in winter and summer seasons, respectively. Isolates (128 strains) were identified by analyzing 16S ribosomal RNA sequences. The number of colonies and bacterial species from biofilms sampled in winter tended to be higher and lower, respectively, than those in summer. Moreover, the composition of bacterial communities in summer and winter samples differed considerably. In summer samples, biofilms in Kansai and Kanto areas were dominated by Blastomonas sp. and Mycobacterium sp., respectively. Methylobacterium sp. was detected in all toilet bowl biofilms except for one sample. Methylobacterium sp. constituted the major presence in biofilms along with Brevundimonas sp., Sphingomonas sp., and/or Pseudomonas sp. The composition ratio of the sum of their genera was 88.0 from 42.9% of the total bacterial flora. The biofilm formation abilities of 128 isolates were investigated, and results suggested that Methylobacterium sp. and Sphingomonas sp. were involved in biofilm formation in toilet bowls. The biofilm formation of a mixed bacteria system that included bacteria with the highest biofilm-forming ability in a winter sample was greater than mixture without such bacteria. This result suggests that isolates possessing a high biofilm-forming activity are involved in the biofilm formation in the actual toilet bowl. A bactericidal test against 25 strains indicated that the bactericidal activities of didecyldimethylammonium chloride (DDAC) tended to be higher than those of polyhexamethylene biguanide (PHMB) and N-benzyl-N,N-dimethyldodecylammonium chloride (ADBAC). In particular, DDAC showed high bactericidal activity against approximately 90% of tested strains under the 5 h treatment.

    Highlights: • The RCCI engine fueled with gasoline and biodiesel is simulated. • The effect of piston bowl geometry is investigated. • The throat diameter of a piston can affect combustion process. • SCC shows superiority among three investigated geometries for RCCI combustion. - Abstract: This paper reports the numerical investigation on the effects of three bowl geometries on a gasoline/biodiesel fueled RCCI engine operated at high engine speed. The three bowl geometries are HCC (Hemispherical Combustion Chamber), SCC (Shallow depth Combustion Chamber) and OCC (Omega Combustion Chamber). To simulate the combustion in an RCCI engine, coupled KIVA4–CHEMKIN code was used. One recently developed reaction mechanism, which contains 107 species and 425 reactions, was adopted in this study to mimic the combustion of gasoline and biodiesel. During the simulation, the engine speed was fixed at 3600 rpm. The low reactivity fuel gasoline was premixed with air with energy percentages of 20% and 40%; accordingly, to maintain the same energy input, the percentages of biodiesel were 80% and 60% (B80 and B60). In addition, the SOI timing was varied at three levels: −11, −35 and −60 deg ATDC for B80 and B60, respectively. With SOI timing of −11 deg ATDC, the combustion is mixing-controlled; in contrast, advancing SOI timing to −60 deg ATDC, the combustion turns into the reactivity-controlled. Comparing the results on combustion characteristics, engine performance and emissions among different bowl geometries, it is concluded that the original OCC design for Toyota diesel engine is better for mixing-controlled combustion; whereas, SCC is the most suitable piston design for RCCI combustion among the three selected geometries under the investigated operating conditions of the engine. With SCC, better combustion and performance can be achieved while maintaining relatively lower CO, NO and soot emissions.

    We have previously conducted a microflora analysis and examined the biofilm-forming activity of bacteria isolated from toilet bowl biofilms. In the present investigation, to reveal the strain involved in the formation of black dirt in toilet bowls, we performed a microflora analysis of the bacteria and fungi isolated from the black dirt of toilet bowls at ten homes. Among samples from different isolation sites and sampling seasons, although a similar tendency was not seen in bacterial microflora, Exophiala sp. was detected in the fungal microflora from all samples of black dirt except for one, and constituted the major presence. By scanning electron microscope (SEM) analysis of the formed black dirt, SEM image at × 1,000 and × 5,000 magnification showed objects like hyphae and many bacteria adhering to them, respectively. Micro fourier transform infrared spectroscopy (micro FT-IR) and SEM with X-ray microanalysis (SEM-XMA) were used to investigate the components of black dirt. IR spectra of micro-FT-IR showed typical absorptions associated with amide compounds and protein, and the elements such as C, N, O, Na, Mg, Al, Si, P, S, K, and Ba were detected with SEM-XMA. These results showed that black dirt had living body ingredients. Furthermore, Exophiala sp. and Cladosporium sp. strains, which were observed at a high frequency, accumulated 2-hydroxyjuglone (2-HJ) and flaviolin as one of the intermediates in the melanin biosynthetic pathway by the addition of a melanin synthesis inhibitor (tricyclazole) at the time of cultivation. These results suggested strongly that the pigment of black dirt in toilet bowls was melanin produced by Exophiala sp. and Cladosporium sp. strains.

    This research explored the adoption and the utilisation of telemedicine (TM) in two healthcare organizations (HCOs) in New Zealand (NZ). The research utilised the technological innovation theories, as a guiding theoretical framework, to develop a set of potential determinants which could assist in understanding the adoption and the depth of the TM phenomenon in the two HCOs. Using case studies design, the findings across the two cases revealed that TM was adopted according to its cost-benefit analysis. Although this approach was found to be important in assessing the adoption of TM, not considering the importance of other factors, highlighted in this research, such as the compatibility and the trialability aspects of the TM technology had a detrimental impact on the success of TM in both cases. This research stressed the need for the tight coupling between the roles of both the administrative and the clinical managers in HCOs in order to champion TM adoption and diffusion and to overcome many of the barriers that could hinder telemedicine success in HCOs in NZ. The research points to other implications with respect to the literature and highlights further research in this important area.

    Full Text Available A media competition was part of the Massachusetts Childhood Obesity Research Demonstration (MA-CORD Study. Criss et al., previously outlined the development and implementation of the competition, including variation in reach and adoption of the intervention across schools and afterschool programs. In this qualitative study, we examine community, provider, and organizational factors that explain the variation of media competition reach in school and afterschool programs, and describe the awareness of the media competition across other community sectors. Durlak and DuPre’s ecological framework for understanding effective implementation provided the theoretical underpinnings for this study. Fifty-four key informant interviews were conducted, transcribed, and analyzed. Organizational capacity of committed teachers/staff and adaptability of the media competition seemed to be drivers for higher reach within school and afterschool programs. Salient themes that emerged as facilitators of effective implementation were having a cascade of champions and providing opportunity to participate in the media competition outside traditional class time. Clinics and coalitions were identified as additional sectors aware of the media competition. Specifically, our findings offer a new perspective on intervention design and a recommended direction for further study.

    Dementia in retired boxers, also referred to as "dementia pugilistica" (DP), is usually attributed to repeated concussive and subconcussive blows to the head. We report the case of a former world boxing champion whose progressive cognitive decline could be ascribed to DP, cerebral infarcts and Wernicke-Korsakoff syndrome. This case demonstrates that dementia in retired boxers may be caused and/or exacerbated by etiologic factors other than DP. We correlated the clinical features with the histochemical and immunohistochemical changes observed on autopsy brain material from a retired boxer, reviewed the literature on boxing-related dementia, and compared our findings with previous reports on DP. Neuropathologic examination revealed numerous neurofibrillary tangles (NFTs), rare neuritic plaques (NPs), multiple cerebral infarcts, fenestrated septum pellucidum, atrophic and gliotic mamillary bodies, and pale substantia nigra and locus ceruleus. Our neuropathologic data confirmed the notion that dementia in retired boxers could be due to several factors such as DP, multiple cerebral infarcts and Wernicke-Korsakoff syndrome. Our findings illustrate the need to comprehensively examine former boxers with dementia as well as carefully evaluate the neuropathologic changes that may cause or contribute to the patient's cognitive and behavioral symptoms. Such an approach is crucial in order to provide prompt and more definitive therapies.

    Background Pediatric medical and nursing education lack the environmental health content needed to properly prepare health care professionals to prevent, recognize, manage, and treat environmental exposure–related diseases. The need for improvements in health care professionals’ environmental health knowledge has been expressed by leading institutions. However, few studies have evaluated the effectiveness of programs that incorporate pediatric environmental health (PEH) into curricula and practice. Objective We evaluated the effectiveness of the National Environmental Education Foundation’s (NEEF) Children’s Environmental Health Faculty Champions Initiative, which is designed to build environmental health capacity among pediatric health care professionals. Methods Twenty-eight pediatric health care professionals participated in a train-the-trainer workshop, in which they were educated to train other health care professionals in PEH and integrate identified PEH competencies into medical and nursing practice and curricula. We evaluated the program using a workshop evaluation tool, action plan, pre- and posttests, baseline and progress assessments, and telephone interviews. Results During the 12 months following the workshop, the faculty champions’ average pretest score of 52% was significantly elevated (p < 0.0001) to 65.5% on the first posttest and to 71.5% on the second posttest, showing an increase and retention of environmental health knowledge. Faculty champions trained 1,559 health care professionals in PEH, exceeding the goal of 280 health care professionals trained. Ninety percent of faculty champions reported that PEH had been integrated into the curricula at their institution. Conclusion The initiative was highly effective in achieving its goal of building environmental health capacity among health care professionals. The faculty champions model is a successful method and can be replicated in other arenas. PMID:19478972

    Despite a perception that retired professional football players have poor health, there are little supporting data. Retired football players have poor health compared with age-matched population norms. Cross-sectional study; Level of evidence, 4. Thirty-six of 41 members of the 1969 Super Bowl winning team were contacted 35 years after that event (3 were deceased, and no contact information was available for 2). Players completed an SF-36 health survey and a medical history and football-specific questionnaire. Each player's football-related injury history before 1969 was documented from medical records. It was estimated that there was 80% power to detect a 10% difference in physical and mental health scores between the retired football players (age, 62 +/- 3 y) and population norms (n = 741) at an alpha level of 0.05. SF-36 scores for physical and mental health were not different from age-matched norms (physical health P = .69; mental health P = .49). The most prevalent medical conditions were arthritis (24 of 36 players), hypertension (13 of 36 players), and chronic low back pain (13 of 36 players). SF-36 physical health scores were 21% lower in players with arthritis (P football for 8.3 +/- 3.8 years, and 33 players (94%) reported having had "very fulfilling" (n = 24) or "somewhat fulfilling" (n = 9) careers. These professional football players had long and fulfilling careers with no apparent long-term detrimental effects on physical or mental health scores despite a high prevalence of arthritis.

    Full Text Available The synergistic interaction between teammates in association football has properties that can be captured by Social Network Analysis (SNA. The analysis of networks formed by team players passing a ball in a match shows that team success is correlated with high network density and clustering coefficient, as well as with reduced network centralization. However, oversimplification needs to be avoided, as network metrics events associated with success should not be considered equally to those that are not. In the present study, we investigated whether network density, clustering coefficient and centralization can predict successful or unsuccessful team performance. We analyzed 12 games of the Group Stage of UEFA Champions League 2015/2016 Group C by using public records from TV broadcasts. Notational analyses were performed to categorize attacking sequences as successful or unsuccessful, and to collect data on the ball-passing networks. The network metrics were then computed. A hierarchical logistic-regression model was used to predict the successfulness of the offensive plays from network density, clustering coefficient and centralization, after controlling for the effect of total passes on successfulness of offensive plays. Results confirmed the independent effect of network metrics. Density, but not clustering coefficient or centralization, was a significant predictor of the successfulness of offensive plays. We found a negative relation between density and successfulness of offensive plays. However, reduced density was associated with a higher number of offensive plays, albeit mostly unsuccessful. Conversely, high density was associated with a lower number of successful offensive plays (SOPs, but also with overall fewer offensive plays and “ball possession losses” before the attacking team entered the finishing zone.

    To test the hypothesis that elite rowers would possess a faster, more economic oxygen uptake response than club standard rowers. Eight Olympic champion (ELITE) rowers were compared with a cohort of eight club standard (CLUB) rowers. Participants completed a progressive exercise test to exhaustion, repeated 6-min moderate and heavy square-wave transitions, and a maximal 2000-m ergometer time trial. The time constant (tau) of the primary component (PC) was faster for the ELITE group compared with CLUB for moderate-intensity (13.9 vs 19.4 s, P = 0.02) and heavy-intensity (18.7 vs 22.4 s, P = 0.005) exercise. ELITE rowers consumed less oxygen for moderate (14.2 vs 15.6 mL x min(-1) x W(-1); P = 0.009) and heavy (12.1 vs 13.7 mL x min(-1) x W(-1); P = 0.01) exercise. A greater absolute slow component was observed in the ELITE group (P = 0.009), but no differences were noted when the slow component was expressed relative to work rate performed (P = 0.14). Intergroup correlation with time trial performance speed was significant for tauPC during heavy-intensity exercise (r = -0.59, P = 0.02). Compared with CLUB rowers, the shorter time constant response and greater economy observed in ELITE rowers may suggest advantageous adjustment of oxidative processes from rest to work. Training status or performance level do not seem to be associated with a smaller slow component when comparing CLUB and ELITE oarsmen.

    2006-09-01

    Liberalisation of Dutch energy markets was not a sudden change of policy direction, but rather the result of policy evaluations and discussions which had already been going on for quite some time when the Minister of Economic Affairs issued an Energy White Paper in early 1996, and the EU Directives for the electricity market (1996) and the gas market (1998) were introduced. The Dutch followed a two-way track, aiming at a phased market liberalisation for gas and electricity with full legal electricity network unbundling and a merger of the four large power generators into a national champion. For gas, the Dutch position as a major natural gas producer led to the proposition of a structure that was much more careful, following the EU Directive to the millimetre. Some ten years since the White Paper was issued, Dutch decision-making, legislation and regulation of the energy market has gone through a fascinating, burdensome and complex, and sometimes chaotic and frustrating process. This study highlights the importance of market dynamics and the almost unbearable and unsolvable balance between policy, legislation and regulation. Further attention is given to the role of Dte ( Office of Energy Regulation) and its evolution into a full merger with the NMa (Netherlands Competition Authority), and ownership and privatisation discussions against the backdrop of the developments in the wider European energy markets. Overall, the study concludes that it appears to be too early to tell whether energy market policies of the last decade have delivered the expected results in either quantitative or monetary terms. What the process did deliver, however, was a lot of turbulence and dynamics, a boost for innovation in marketing and technology drives, and increased awareness about consumer power in which the threat to switch in itself produces results of improved service, more transparency and increased accountability

    As a result of increases in CO{sub 2} and other radiatively important trace gases, scientists have predicted increases in mean worldwide temperatures of 2--5 degrees C over the next 50 to 100 years. Such temperature increases may result in climate modifications that would in turn be associated with increases in drought and desertification and could even change the patterns of the monsoons and tropical rains, which are important to agriculture throughout the world. They predicted that the rise in sea level caused by melting and thermal expansion of glaciers and polar icecaps could flood large population centers, destroying habitation and displacing populations. This will result in approximately 50 million ``environmental refugees`` worldwide, triple the number of today. The expected shifts in precipitation are also likely to result in (1) increased runoff contaminated with pesticides, salts, garbage, sewage, and eroded soil, and (2) drought also leading to increased soil erosion and salinization, as well as depletion of limited water resources. The total impact of global warming on agriculture and human habitation could considerably slow the economic development of some nations and would particularly affect agricultural production. Loss of homes, the inability to raise food, an increased prevalence of disease and worsened economic conditions may drive people to leave their homelands, seeking entry into countries which have more resources and greater resistance to the economic consequences of climatic change. This report looks at the possible environmental impacts and economic impacts of the greenhouse effect on Mexico while using the American Dust Bowl event as an analog.

    Breast cancer is the leading cause of cancer deaths in Malaysian women, and the use of breast self-examination (BSE), clinical breast examination (CBE) and mammography remain low in Malaysia. Therefore, there is a need to develop a valid and reliable tool to measure the beliefs that influence breast cancer screening practices. The Champion's Health Belief Model Scale (CHBMS) is a valid and reliable tool to measure beliefs about breast cancer and screening methods in the Western culture. The purpose of this study was to translate the use of CHBMS into the Malaysian context and validate the scale among Malaysian women. A random sample of 425 women teachers was taken from 24 secondary schools in Selangor state, Malaysia. The CHBMS was translated into the Malay language, validated by an expert's panel, back translated, and pretested. Analyses included descriptive statistics of all the study variables, reliability estimates, and construct validity using factor analysis. The mean age of the respondents was 37.2 (standard deviation 7.1) years. Factor analysis yielded ten factors for BSE with eigenvalue greater than 1 (four factors more than the original): confidence 1 (ability to differentiate normal and abnormal changes in the breasts), barriers to BSE, susceptibility for breast cancer, benefits of BSE, health motivation 1 (general health), seriousness 1 (fear of breast cancer), confidence 2 (ability to detect size of lumps), seriousness 2 (fear of long-term effects of breast cancer), health motivation 2 (preventive health practice), and confidence 3 (ability to perform BSE correctly). For CBE and mammography scales, seven factors each were identified. Factors for CBE scale include susceptibility, health motivation 1, benefits of CBE, seriousness 1, barriers of CBE, seriousness 2 and health motivation 2. For mammography the scale includes benefits of mammography, susceptibility, health motivation 1, seriousness 1, barriers to mammography seriousness 2 and health

    A table tennis player should fixate at different distances; track the objects with different speed, and in different visual environment. Their visual skills must be well developed for these capabilities. Therefore, visual acuity in reduced lumination and facility of ocular accommodation those are two criteria for visual skills have been compared in table tennis players and normal non-players. Twenty-nine young table tennis champions and 29 normal matched non-players (did not take part in any racket sports game) were evaluated. Basic visual and eye examinations were done for both of them. Normal results in basic examination were fundamental requirement for all the subjects. +/-2.00 sphere lenses for accommodation facility are used. An electrical current regulator changed the output light intensity of a conventional chart projector (Topcon). Light intensity decreased to 10 cd·m(-2) and visual acuity tested. In comparison of visual acuity in reduced lumination and facility of ocular accommodation in table tennis champions and non-players there are significant differences (p reflecting a better perceptual system of experts to the constraints encountered during table tennis and its use in practical settings for evaluating athletes or detecting sport talents. However some visual and perceptual training that usually used in orthoptics can be used for novice table tennis player to improve their abilities. Key PointsThat the ability of a champion depends on many sensory, motor and perceptual factors.Visual factors such as facility of accommodation and visual acuity in reduced lumination should be considered in table tennis players.Visual training may be useful for novice and also for experts.

    To create a clinical competency committee (CCC) that (1) centers on the competency-based milestones, (2) is simple to implement, (3) creates competency expertise, and (4) guides remediation and coaching of residents who are not progressing in milestone performance evaluations. We created a CCC that meets monthly and at each meeting reviews a resident class for milestone performance, a competency (by a faculty competency champion), a resident rotation service, and any other resident or issue of concern. University surgical residency program. The CCC members include the program director, associate program directors, director of surgical curriculum, competency champions, departmental chair, 2 at-large faculty members, and the administrative chief residents. Seven residents were placed on remediation (later renamed as coaching) during the academic year after falling behind on milestone progression in one or more competencies. An additional 4 residents voluntarily placed themselves on remediation for medical knowledge after receiving in-training examination scores that the residents (not the CCC membership) considered substandard. All but 2 of the remediated/coached residents successfully completed all area milestone performance but some chose to stay on the medical knowledge competency strategy. Monthly meetings of the CCC make milestone evaluation less burdensome. In addition, the expectations of the residents are clearer and more tangible. "Competency champions" who are familiar with the milestones allow effective coaching strategies and documentation of clear performance improvements in competencies for successful completion of residency training. Residents who do not reach appropriate milestone performance can then be placed in remediation for more formal performance evaluation. The function of our CCC has also allowed us opportunity to evaluate the required rotations to ensure that they offer experiences that help residents achieve competency performance necessary

    Improving the energy storage performance of supercapacitor electrodes based on reduced graphene oxide (RGO) is one of the main subjects in this research field. However, when a zirconia bowl and zirconia balls were used for ball-mill mixing of the active materials for RGO supercapacitors, the energy storage performance deteriorated over time. Our study revealed that the source of the problem was the inclusion of zirconia bits from abrasion of the bowl and the balls during the ballmill mixing, which increased during a period of 1 year. We probed two solutions to this problem: 1) hydrofluoric (HF) acid treatment of the RGO supercapacitors and 2) use of a tempered steel bowl and tempered steel balls for the mixing. For both cases, the energy storage performance was restored to near the initial level, showing a specific capacitance ( C sp ) of 200 F/g. Our results should lead to progress in research on RGO supercapacitors.

    In the 3D laser forming process, developing an appropriate laser scan pattern for producing specimens with high quality and uniformity is critical. This study presents certain principles for developing scan paths. Seven scan path parameters are considered, including: (1) combined linear or curved path; (2) type of combined linear path; (3) order of scan sequences; (4) the position of the start point in each scan; (5) continuous or discontinuous scan path; (6) direction of scan path; and (7) angular arrangement of combined linear scan paths. Regarding these path parameters, ten combined linear scan patterns are presented. Numerical simulations show continuous hexagonal, scan pattern, scanning from outer to inner path, is the optimized. In addition, it is observed the position of the start point and the angular arrangement of scan paths is the most effective path parameters. Also, further experimentations show four sequences due to creat symmetric condition enhance the height of the bowl-shaped products and uniformity. Finally, the optimized hexagonal pattern was compared with the similar circular one. In the hexagonal scan path, distortion value and standard deviation rather to edge height of formed specimen is very low, and the edge height despite of decreasing length of scan path increases significantly compared to the circular scan path. As a result, four-sequence hexagonal scan pattern is proposed as the optimized perimeter scan path to produce bowl-shaped product.

    Super Bowl XLIX took place on February 1, 2015, in Glendale, Arizona. In preparation for this event and associated activities, the Maricopa County Department of Public Health (MCDPH) developed methods for enhanced surveillance, situational awareness, and early detection of public health emergencies. Surveillance strategies implemented from January 22 to February 6, 2015, included enhanced surveillance alerts; animal disease surveillance; review of NFL clinic visits; syndromic surveillance for emergency room visits, urgent care facilities, and hotels; real-time onsite syndromic surveillance; all-hazards mortality surveillance; emergency medical services surveillance, review of poison control center reports; media surveillance; and aberration detection algorithms for notifiable diseases. Surveillance results included increased influenzalike illness activity reported from urgent care centers and a few influenza cases reported in the NFL clinic. A cyanide single event exposure was investigated and determined not to be a public health threat. Real-time field syndromic surveillance documented minor injuries at all events and sporadic cases of gastrointestinal and neurological (mostly headaches) disease. Animal surveillance reports included a cat suspected of carrying plague and tularemia and an investigation of highly pathogenic avian influenza in a backyard chicken flock. Laboratory results in both instances were negative. Aberration detection and syndromic surveillance detected an increase in measles reports associated with a Disneyland exposure, and syndromic surveillance was used successfully during this investigation. Coordinated enhanced epidemiologic surveillance during Super Bowl XLIX increased the response capacity and preparedness of MCDPH to make informed decisions and take public health actions in a timely manner during these mass gathering events.

    Full Text Available Objective. This study aimed at determining the microbial content of “bowl water” used for communal handwashing in preschools within the Accra Metropolis. Method. Six (6 preschools in the Accra Metropolis were involved in the study. Water samples and swabs from the hands of the preschool children were collected. The samples were analysed and tested for bacteria, fungi, parasites, and rotavirus. Results. Eight different bacteria, two different parasites, and a fungus were isolated while no rotavirus was detected. Unlike the rest of the microbes, bacterial isolates were found among samples from all the schools, with Staphylococcus species being the most prevalent (40.9%. Out of the three schools that had parasites in their water, two of them had Cryptosporidium parvum. The fungus isolated from two out of the six schools was Aspergillus niger. All bacteria isolated were found to be resistant to cotrimoxazole, ciprofloxacin, and ampicillin and susceptible to amikacin and levofloxacin. Conclusion. Although handwashing has the ability to get rid of microbes, communal handwashing practices using water in bowls could be considered a possible transmission route and may be of public concern.

    There are limited accounts of community-based interventions for reducing distress or providing support for people with common mental disorders (CMDs) in low and middle-income countries. The recently implemented Atmiyata programme is one such community-based mental health intervention focused on promoting wellness and reducing distress through community volunteers in a rural area in the state of Maharashtra, India. This case study describes the content and the process of implementation of Atmiyata and how community volunteers were trained to become Atmiyata champions and mitras ( friends ). The Atmiyata programme trained Atmiyata champions to provide support and basic counselling to community members with common mental health disorders, facilitate access to mental health care and social benefits, improve community awareness of mental health issues, and to promote well-being. Challenges to implementation included logistical challenges (difficult terrain and weather conditions at the implementation site), content-related challenges (securing social welfare benefits for people with CMDs), and partnership challenges (turnover of public health workers involved in referral chain, resistance from public sector mental health specialists). The case study serves as an example for how such a model can be sustained over time at low cost. The next steps of the programme include evaluation of the impact of the Atmiyata intervention through a pre-post study and adapting the intervention for further scale-up in other settings in India.

    The aim of this study was to analyse qualification patterns in middle distance running and identify whether athletes adopt theoretically optimal tactics, or whether the will to win overrides these. The performances of 295 men and 258 women finalists in the Olympic and IAAF World Championship 800 m and 1500 m events from 1999 to 2017 were analysed across all three rounds of competition. Finishing position, time and ranking amongst all competitors were found for each athlete. Position in the final was correlated with finishing position in the heats and semi-finals (all P < 0.001), but not with finishing times in those rounds. Of the 57 champions, 40 won both their heat and semi-final, even though a lower automatic qualification position would have been sufficient, and only 18 achieved a season's best time in the final. The will to win amongst the eventual champions (and other medallists) suggests predominantly ego oriented behaviour that is encouraged by a performance climate, and which did not appear to differ between men and women. Coaches and athletes are recommended to note that championship-specific physiological and psychological factors are important to develop in training and prior competition to improve both short- and long-term championship strategies.

    Objectives To identify the barriers to and facilitators of implementing guidelines for targeted temperature management (TTM) after cardiac arrest perceived by hospital resuscitation champions and to investigate the changes in their perceptions over the early implementation period. Design A longitudinal qualitative study (up to 2 serial semistructured interviews over 1 year and focus groups). The individual interviews and focus groups were transcribed and coded by 2 independent assessors. Contents were analysed thematically; group interaction was also examined. Setting 21 hospitals, including community and tertiary care centres in South Korea. Participants 21 hospital champions (14 acting champions and 7 managerial champions). Results The final data set included 40 interviews and 2 focus groups. The identified barriers and facilitators could be classified into 3 major themes: (1) healthcare professionals’ perceptions of the guidelines and protocols, (2) interdisciplinary and interprofessional collaboration and (3) organisational resources. Lack of resources was the most commonly agreed on barrier for the acting champions, whereas lack of interdisciplinary collaboration was the most common barrier for the managerial champions. Educational activities and sharing successfully treated cases were the most frequently identified facilitators. Most of the participants identified and agreed that cooling equipment was an important barrier as well as a facilitator of successful TTM implementation. Perception of the guidelines and protocols has improved with the accumulation of clinical experience over the study period. Conclusions Healthcare professionals’ internal barriers to TTM implementation may be influenced by new guidelines and can be changed with the accumulation of successful clinical experiences during the early implementation period. Promoting interprofessional and interdisciplinary collaboration through educational activities and the use of cooling equipment

  8. Investigating a Possible New Heavyweight Champion for Stellar Mass Black Holes with XMM-Newton

    Science.gov (United States)

    Barnard, Robin

    luminosities > 3E+37 erg/s (10% Eddington for the most massive known neutron star) then we classify the XB as a BHC. XBo 135 is associated with the globular cluster Bo 135 in M31, making it a very likely XB. The highest quality XMM-Newton spectrum to date revealed a low state spectrum at a luminosity of 4.4 E+38 erg/s, while Chandra observations suggest low state emission up to 6 E+38 erg/s (0.3-10 keV). We infer from these results a black hole mass >50 solar masses; the current champion is IC10 X-1, which is a dynamically confirmed BH + Wolf-Rayet binary with a 33 solar mass BH. We have been granted a 120 ks XMM-Newton observation of XBo 135 in order to test theoretical scenarios for creating such a monster. In particular, we will be estimating the metallicity of the environs of XBo 135, to determine whether direct collapse of a metal poor, high mass star is feasible. Stars with metallicity 40 solar masses are expected to form 30-80 solar mass black holes via direct collapse, because the low metallicity prevents significant mass loss from the stellar wind over the stars lifetimes. We will follow a published method that was used to determine the metallicities of several so-called ultra-luminous X-ray sources (ULXs), which have X-ray luminosities that exceed the Eddington limit for typical stellar mass black holes ( 2 E+39 erg/s). The key parameters to measure are the hydrogen abundance, a 542 eV oxygen K absorption edge, and an 851 eV iron L absorption edge. We will fit CCD (pn + MOS) and grating (RGS) spectra simultaneously to get the best measurements of these features. If XBo 135 were found to be a 50 solar mass BH formed in a globular cluster via direct collapse, then its importance would exceed that of just being the heaviest known stellar mass black hole- similar systems could form intermediate mass black holes, and possibly even supermassive black holes.

    Highlights: • A unique bowl-like hollow spherical Co 3 O 4 structure is prepared through a simple, low-cost and mass-yield method. • Such a bowl-like hollow Co 3 O 4 microsphere demonstrates extraordinary rate and cycling performance for Li-storage. • The sodium-storage behavior of Co 3 O 4 is investigated for the first time. - Abstract: Bowl-like hollow Co 3 O 4 microspheres are prepared via a simple and low-cost route by thermally treating Co-containing resorcinol-formaldehyde composites gel in air. Scanning electron microscopy, transmission electron microscope and N 2 adsorption-desorption measurements demonstrate that these bowl-like hollow Co 3 O 4 microspheres are composed of hollow inner cavities and outer shell walls (70 nm thickness), on which a considerable amount of mesopores centered around 5-17 nm size are distributed. When employed as the anode material for lithium-ion batteries, these bowl-like hollow Co 3 O 4 microspheres exhibit extraordinary cycling performance (111% retention after 50 cycles owing to capacity rise), fairly high rate capacity (650 mAh g −1 at 5 C) and enhanced lithium storage capacity. Meanwhile, the Na-storage behavior of Co 3 O 4 as an anode material of Na-ion batteries is initially investigated based on such a hollow structure and it exhibits similar feature of discharge/charge profiles and a high initial discharge capacity but relatively moderate capacity retention compared with the Li-storage performance

    Full Text Available A table tennis player should fixate at different distances; track the objects with different speed, and in different visual environment. Their visual skills must be well developed for these capabilities. Therefore, visual acuity in reduced lumination and facility of ocular accommodation those are two criteria for visual skills have been compared in table tennis players and normal non-players. Twenty-nine young table tennis champions and 29 normal matched non-players (did not take part in any racket sports game were evaluated. Basic visual and eye examinations were done for both of them. Normal results in basic examination were fundamental requirement for all the subjects. +/-2.00 sphere lenses for accommodation facility are used. An electrical current regulator changed the output light intensity of a conventional chart projector (Topcon. Light intensity decreased to 10 cd·m-2 and visual acuity tested. In comparison of visual acuity in reduced lumination and facility of ocular accommodation in table tennis champions and non-players there are significant differences (p < 0.001. In the preliminary visual tests there was not any significant different in the two groups but the results in the top level table tennis player was very uniform and in every test and the standard deviation was lesser in tennis player group than non-players. These results show that motor and sensorial functions of expert players are well developed. That is consistent with other researchers. This result was interpreted as reflecting a better perceptual system of experts to the constraints encountered during table tennis and its use in practical settings for evaluating athletes or detecting sport talents. However some visual and perceptual training that usually used in orthoptics can be used for novice table tennis player to improve their abilities

    The drought that struck the U.S. Great Plains during the 1930s was one of the most intensedroughts in the region in the last millennium, spurring a major environmental and public healthcrisis. A prominent explanation for the cause of the "dust bowl" centers on the expansion ofagriculture and poor land management practices leading to widespread soil erosion. Thisprevalent hypothesis largely excludes the impacts of naturally occurring land surface processesthat contribute to eolian erosion and dust emissivity, particularly during periods of drought. Priorwork generally focuses on economic and sociological factors in agricultural decision-making forindividual fields or farms.This study utilizes early aerial photography collected by the Soil Conservation Service in 1936 ofBaca County, Colorado, to identify and quantify spatial relationships between geomorphicprocesses and anthropogenic activities impacting dust emission. From the holdings at theNational Archives, 25 photos covering 125 km2 scanned at 1200dpi are combined into acontinuous mosaic, and geo-referenced at RMSE 78.6 m2 . Detailed land cover analyses areundertaken in ArcGIS to classify uncultivated and cultivated surfaces; cultivated surfaces arefurther divided by surface agricultural operations in relation to erosion and dust emission (e.g.listing, contour furrows, terraces, circuitous plowing, listing, eolian transport, and fallow fieldswith and without vegetation). The classified surface is overlaid with National ResourceConservation Service surveys and Soil Conservation Service reconnaissance surveys of land useand erosion carried out in 1936 to infer to potential emissivity of a given cultivated surface. Inthis way, it becomes possible to evaluate human influence on dust emission in one of theworst-struck counties of the Dust Bowl and potentially identify other causative factors to thissignificant period in American history.

    Full Text Available The last three decades have been a story of lost opportunities for Spanish industry to transform and improve their international competitiveness. However, there are some paradigmatic examples that violate this rule. This is the case of two Spanish companies: Hidden Champions and Brand Champions. These companies behave differently from the European and Spanish ones of similar size. They are more resilient in times of economic recession and are able to maintain and even increase their employment levels, while significantly increasing its sales and added value. This research therefore seeks to ascertain whether the Spanish hidden champions are good indicators of maturity, stability and growth of the Spanish economy; in addition to determining the reasons that have brought success and allowed these companies to recover faster than other firms. To do this, we have considered the quantitative and qualitative results collected by 75 Spanish companies to identify key management decisions. All this information is supplemented by personal interviews in order to capture more qualitative aspects about the nature of companies' management practices. The results show a typology of companies that behave differently from other companies. Managers believe that the development of close relations with customers is the first reason related to management that has led where they are today. The second is the continued development of new products and technology through innovation. Thirdly, managers consider internationalization, global approach and international alliances; whereas the fourth reason corresponds to high product specialization. Other reasons include talent management, strong leadership and company identity, quality and service, and close cooperation between managers and employees. || Las tres últimas décadas han sido una historia de oportunidades perdidas para transformar la industria española y mejorar su competitividad internacional.

  15. Dependence of secondary electron emission on the incident angle and the energy of primary electrons bombarding bowl-structured beryllium surfaces

    Kawata, Jun; Ohya, Kaoru.

    1994-01-01

    A Monte Carlo simulation of the secondary electron emission from beryllium is combined with a model of bowl structure for surface roughness, for analyzing the difference between the electron emissions for normal and oblique incidences. At normal incidence, with increasing the roughness parameter H/W, the primary energy E pm at which the maximum electron yield occurs becomes higher, and at more than the E pm , the decrease in the yield is slower; where H and W are the depth and width of the bowl structure, respectively. The dispersion of incident angle to the microscopic surface causes a small increase in the yield at oblique incidence, whereas the blocking of primary electrons from bombarding the bottom of the structure causes an opposite trend. The strong anisotropy in the polar angular distribution with respect to the azimuthal angle is calculated at oblique incidence. (author)

    This research reports on the NICE Evidence search (ES) student champion scheme (SCS) first five years of activity (2011-2016) in terms of its impact on health care undergraduate students' information search skills and search confidence. A review of students' evaluation of the scheme was carried out to chart the changes in attitude towards NICE Evidence search as an online health care information source and to monitor students' approach to information seeking. This study is based on the results of questionnaires distributed to students before and after attending a training session on NICE Evidence search delivered by their own peers. The exercise was implemented in health related universities in England over a period of five consecutive academic years. (i) Students' search confidence improved considerably after the training; (ii) ES was perceived as being an increasingly useful resource of evidence based information for their studies; (iii) the training helped students develop discerning search skills and use evidence based information sources more consistently and critically. The NICE SCS improves confidence in approaching information tasks amongst health care undergraduate students. Future developments could involve offering the training at the onset of a course of study and adopting online delivery formats to expand its geographical reach. © 2018 Health Libraries Group.

    The purpose of this study was to compare the training intensity distribution (TID) of the undefeated world champion male rowing New Zealand (kiwi) pair over a four-year Olympic cycle, across training phases, training years, and between individuals. Training data, including heart rate and boat speed, were recorded in the athletes rowing in the same boat between March 2013 and August 2016, ending with the Rio Olympics final. Progressive exercise tests assessed first (LT 1 ) and second (LT 2 ) lactate thresholds and associated heart rates, to determine the percentage of training performed below, between and above these demarcation points. Training an average of only 12-15 h/wk throughout the Olympic cycle, the mean percent distribution of time (±SD) at each training intensity was 80.4 ± 5.5% LT 2 for Rower A and 67.3 ± 9.0% LT 2 for Rower B. Across the years 2014-2016, Rower A performed most likely more training training between LT 1 -LT 2 . Training appeared to become more polarised, with greater amounts of time spent training duration (R=0.38-0.43). Two of the world's best rowers, rowing together in the same boat with an undefeated record across an Olympic cycle, travelled markedly different "roads to Rio" within the context of their TID, with one rower displaying a polarised model of TID, and the other pyramidal. However, TID trended towards becoming more polarised in both rowers with increased training duration.

    Semiconducting transition-metal dichalcogenide (TMD) nanoflake thin films are promising large-area electrodes for photo-electrochemical solar energy conversion applications. However, their energy conversion efficiencies are typically much lower than those of bulk electrodes. It is unclear to what extent this efficiency gap stems from differences among nanoflakes (e.g., area, thickness, and surface structural features). It is also unclear whether individual exfoliated nanoflakes can achieve energy conversion efficiencies similar to those of bulk crystals. Here, we use a single-nanoflake photo-electrochemical approach to show that there are both highly active and completely inactive nanoflakes within a film. For the exfoliated MoSe2 samples studied herein, 7% of nanoflakes are highly active champions, whose photocurrent efficiency exceeds that of the bulk crystal. However, 66% of nanoflakes are inactive spectators, which are mostly responsible for the overall lower photocurrent efficiency compared to the bulk crystal. The photocurrent collection efficiency increases with nanoflake area and decreases more at perimeter edges than at interior step edges. These observations, which are hidden in ensemble-level measurements, reveal the underlying performance issues of exfoliated TMD electrodes for photo-electrochemical energy conversion applications.

    Olivine-structured LiFePO4/C composites with high rate-performance were synthesized via an industrial spray-drying technique using a low cost Fe3O4 as iron source. The as-obtained LiFePO4/C exhibits a unique bowl-like morphology with a particle size of 2-5 μm in diameter. A continuous uniform carbon coating layer on the surface of LiFePO4/C cathodes promotes fast electron transport, whilst it guarantees the favorable electrochemical reaction. Especially the formation of porous structure leads to an average pore volume of 0.127 cm3 g-1 and a high specific surface area of 34.46 m2 g-1, which is conducive to facilitating the penetration of electrolyte and providing the more contact area of electrolyte with LiFePO4/C. As a result, the as-prepared LiFePO4/C cathode material delivers an outstanding discharge capacity of 102.1 mAh g-1, 94.2% of the initial capacity (108.3 mAh g-1), after 1000 cycles at 10 C. Even at an ultrahigh current rate of 50 C, it still shows an initial discharge capacity of 58 mAh g-1.

    Full Text Available The amount of pollutant gases in the atmosphere has reached a critical state due to an increase in industrial development and the rapid growth of automobile industries that use fossil fuels. The combustion of fossil fuels produces harmful gases such as carbon dioxide, nitrogen monoxide (NO, soot, particulate matter (PM, etc. The use of Dimethyl Ether (DME biofuel in diesel engines or other combustion processes have been highly regarded by researchers. Studies show that the use of pure DME in automotive engines will be possible in the near future. The present work evaluated the environmental and performance effects of changing the injection strategy (time and temperature, piston bowl geometry, and exhaust gas recirculation (EGR composition for a DME-burning engine. The modification of piston bowl parameters and engine simulation were numerically performed by using AVL fire CFD code. For model validation, the calculated mean pressure and rate of heat released (RHR were compared to the experimental data and the results showed a good agreement (under a 70% load and 1200-rpm engine speed. It was found that retarding injection timing (reduction in in-cylinder temperature, consequently caused a reduction in NO emissions and increased soot formation, reciprocally; this occurred because of a reduction in temperature and a lower soot oxidation in the combustion chamber. It became clear that 3 deg before top dead center (BTDC was the appropriate injection timing for the DME-burning heavy duty diesel engine running under 1200 rpm. Also, the parametrical modification of the piston bowl geometry and the simultaneous decrease of Tm (piston bowl depth and R3 (bowl inner radius lengths were associated with lower exhaust NO emissions. For the perfect utilization of DME fuel in an HD diesel engine, the suggested proper lengths of Tm and R3 were 0.008 and 0.0079 m, respectively. Furthermore, various EGR compositions for the reduction of exhaust NO were investigated

    Healthy Living Pharmacies (HLP) were introduced in the United Kingdom (UK) in a further attempt to deliver public health benefits in community pharmacy settings. Central to the initiative are staff trained as Healthy Living Champions (HLC) and this study sought to explore HLC perceptions of positive and negative aspect of their work and the wider scheme. A qualitative study was undertaken with a purposive sample of HLCs working in pathfinder HCPs in the Sheffield area in 2014. Participants were recruited by email to either a focus group (n = 7) held at a training event or later semi-structured one-to-one interviews in pharmacies (n = 6). Four stages of interpretative phenomenological analysis were used to code and identify themes. Four main themes emerged relating to the positive workforce development impact HLPs had upon HLCs themselves and on perceived customer and patient engagement and benefits. Tensions were identified with existing commercial business demands and negative views overall of the pharmacy setting with a perceived lack of not only integration with other services but also awareness among the public and health care staff. HLCs felt empowered and more confident in initiating conversation about health issues with patients, but identified barriers relating to workload, a lack of time to perform their role, isolation, tensions with non-HLC staff and logistical barriers such as poor Internet access. Delivering public health activities through the HLC role in UK pharmacies is associated with several perceived benefits for different stakeholders, but may be threatened by well recognised barriers in UK pharmacies related to the commercial setting. © 2016 Royal Pharmaceutical Society.

    Despite improvements in percutaneous coronary intervention (PCI), intraprocedural thrombotic events (IPTE) and bleeding complications occur and are prognostically important. These have not been included in prior economic studies. PHOENIX ECONOMICS was a substudy of the CHAMPION PHOENIX trial, evaluating cangrelor during PCI. Hospital bills were reviewed from 1,171 patients enrolled at 22 of 63 US sites. Costs were estimated using standard methods including resource-based accounting, hospital billing data, and the Medicare fee schedule. Bleeding and IPTE, defined as abrupt vessel closure (transient or sustained), new/suspected thrombus, new clot on wire/catheter, no reflow, side-branch occlusion, procedural stent thrombosis or urgent need for CABG were identified. Costs were calculated according to whether a complication occurred and type of event. Multivariate analyses were used to estimate the incremental costs of IPTE and postprocedural events. IPTE occurred in 4.3% and were associated with higher catheterization laboratory and overall index hospitalization costs by $2,734 (95%CI $1,117, $4,351; P = 0.001) and $6,354 (95% CI $4,122, $8,586; P < 0.001), respectively. IPTE were associated with MI (35.4% vs. 3.6%; P < 0.001), out-of-laboratory stent thrombosis (4.2% vs. 0.1%; 0 = 0.005), ischemia driven revascularization (12.5% vs. 0.3%; P < 0.001), but not mortality (2.1% vs. 0.2%; P = 0.12) vs. no procedural thrombotic complication. By comparison, ACUITY minor bleeding increased hospitalization cost by $1,416 (95%CI = 312, $2,519; P = 0.012). ACUITY major bleeding increased cost of hospitalization by $7,894 (95%CI $4,154, $11,635; P < 0.001). IPTE and bleeding complications, though infrequent, are associated with substantial increased cost. These complications should be collected in economic assessments of PCI. © 2018 Wiley Periodicals, Inc.

  8. Are Dogs That Are Fed from a Raised Bowl at an Increased Risk of Gastric Dilation Volvulus Compared with Floor-Fed Dogs?

    Directory of Open Access Journals (Sweden)

    Louise Anne Buckley

    2017-01-01

    Full Text Available There are only two studies that study the effect of raised feeders on the risk of Gastric Dilatation Volvulus (GDV and their findings conflict. Only one study found a significant effect of feeder height, with large and giant breeds fed from a raised feeder being at an increased risk of GDV floor fed dogs. However, these authors found that, where the feeder was raised, the height of the feeder that increased the GDV risk was affected by the size of the dog. Large breed dogs were more likely to develop a GDV if fed from a bowl ≤ 1 foot tall, whereas giant breed dogs were more likely to develop a GDV if fed from a bowl > 1 foot tall. No studies found that feeding from a raised feeder reduced the risk of GDV relative to feeding from the floor. Therefore, the safest option in the absence of further evidence is to advise that owners of ‘at risk’ dogs feed from a feeder on the floor. This may not reduce the risk of GDV, but there is no evidence to suggest that it will increase the risk.

    Clark, Robert; Kraemer, Theresa

    2009-01-01

    Of the estimated 1.7 million residents of nursing homes in the United States, approximately half fall annually; and 11% of these sustain injury. This is twice the rate for persons dwelling in the community. By addressing fall risk, physical therapists have an opportunity to reduce falls which are the leading cause of injury deaths, as well as the most common cause of nonfatal injuries for older adults in the United States. This case report examines the effect of a novel interactive video game intervention to address balance dysfunction in an elderly resident of a nursing home who was at risk for falls. The patient is an 89-year-old resident diagnosed with an unspecified balance disorder and a history of multiple falls. Self reports of gait abnormalities, scores on several clinical measures, and her fall history classified her as having substantial risk for future falls. A nontraditional approach to balance training, employing the Nintendo Wii bowling simulation, was used as intervention for this patient's balance disorder. After 6 one-hour treatment sessions, the patient's Berg Balance Score improved from 48 to 53. On the Dynamic Gait Index, the patient improved her score from 19 to 21. The patient's Timed Up and Go Test improved from 14.9 to 10.5 seconds, all suggesting a reduced risk of falling. The patient's ABC Score improved from 88 to 90%. Physical therapy intervention, using the Nintendo Wii bowling simulation, may have decreased fall risk for this individual.

  10. Hermeneutics of science and multi-gendered science education

    Ginev, Dimitri Jordan

    2008-11-01

    In this paper, I consider the relevance of the view of cognitive existentialism to a multi-gendered picture of science education. I am opposing both the search for a particular feminist standpoint epistemology and the reduction of philosophy of science to cultural studies of scientific practices as championed by supporters of postmodern political feminism. In drawing on the theory of gender plurality and the conception of dynamic objectivity, the paper suggests a way of treating the nexus between the construction of gender within the interrelatedness of scientific practices and the constitution of particular objects of inquiry. At stake is the notion of characteristic hermeneutic situation which proves to be helpful in designing a multi-gendered pedagogy as well.

    Key challenges for mental health healthcare professionals to implement research alongside clinical activity have been highlighted, such as insufficient time to apply research skills and lack of support and resources. We examined the impact of employing dedicated staff to promote research in community mental health clinical settings. Quasiexperiment before and after study. South London and Maudsley National Health Service Foundation Trust. 4455 patients receiving care from 15 community mental health teams between 1 December 2013 and 31 December 2014. The proportion of patients approached for research participation in clinical services where research champions were present (intervention group), and where research champions were not present (comparison group). Patients in the intervention group were nearly six times more likely to be approached for research participation (Adj. OR=5.98; 95% CI 4.96 to 7.22). Investing in staff that promote and drive research in clinical services increases opportunities for patients to hear about and engage in clinical research studies. However, investment needs to move beyond employing short-term staff. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

    2015-01-01

    Governments around the world have expressed interest in developing local medical tourism sectors, framing the industry as an opportunity for economic growth and health system improvement. This article addresses questions about how the desire to develop a medical tourism sector in a country emerges and which stakeholders are involved in both creating momentum and informing its progress. Presenting a thematic analysis of 19 key informant interviews conducted with domestic and international stakeholders in Barbados's medical tourism sector in 2011, we examine the roles that "actors" and "champions" at home and abroad have played in the sector's development. Physicians and the Barbadian government, along with international investors, the Medical Tourism Association, and development agencies, have promoted the industry, while actors such as medical tourists and international hospital accreditation companies are passively framing the terms of how medical tourism is unfolding in Barbados. Within this context, we seek to better understand the roles and relationships of various actors and champions implicated in the development of medical tourism in order to provide a more nuanced understanding of how the sector is emerging in Barbados and elsewhere and how its development might impact equitable health system development. © The Author(s) 2015 Reprints and permissions:]br]sagepub.co.uk/journalsPermissions.nav.

    reversible. This paper describes the functions of the Joint Force; advocates for the capabilities they require to enable partnerships, enhance understanding and advance mission preparedness; and calls for unified leadership of the joint domain and over our military’s joint culture. Our traditional international partners have travelled this road. They too see that clarity on joint functions, joint capability, joint domain leadership, and stewardship over joint culture are vital to their military’s relevance and operational effectiveness – and to their agility and flexibility in the years to come. Their progress is the result of internal professional transformation, as well as the understanding of, and requirement by political leaders and modern defence policy to make this so. Here in Canada, the forming of new government this fall calls for a relook at Defence policy, providing new opportunity to invite that same political leadership and influence. Joint functions, joint capabilities and clear joint leadership are vital to our military’s relevance to, and effectiveness in, our national defence and operations. Joint Forces and the joint domain, like strong and capable Army, Navy and Air Forces, need to be led, resourced and fully engaged before planes fly, ships sail, and troops deploy. Joint-ness requires external understanding and proponents, and, within the Forces, a clearly identifiable champion. In Canada, these range from ambiguous to absent.

    This article outlines how the melting pot and salad bowl views of cultural diversity have influenced the cultural training of nutrition educators and other health professionals. It explores how these views are changing in reaction to the changing demographics and health disparities seen in the US today and how the cultural training of nutrition educators has not kept up with these changing views. Suggestions for how this cultural education could be modified include placing a greater emphasis on both the cultural self-awareness of nutrition educators and the sociopolitical historical factors that influence the cultural orientation of nutrition educators and their clients.

    Highlights: • Great influence of piston geometry at low load using single injection strategies. • Enhanced combustion development at mid load through optimized piston surface area. • Double injection allows ultra-low NOx and soot levels for the three piston geometries. • Unacceptable soot emissions at high load using single injection and bathtub geometry. • Stepped geometry leads to ultra-clean combustion with lower fuel consumption than CDC. - Abstract: This experimental work investigates the effects of piston bowl geometry on RCCI performance and emissions at low, medium and high engine loads. For this purpose three different piston bowl geometries with compression ratio 14.4:1 have been evaluated using single and double injection strategies. The experiments were conducted in a heavy-duty single-cylinder engine adapted for dual fuel operation. All the tests were carried out at 1200 rev/min. Results suggest that piston geometry has great impact on combustion development at low load conditions, more so when single injection strategies are used. It terms of emissions, it was proved that the three geometries enables ultra-low NOx and soot emissions at low and medium load when using double injection strategies. By contrast, unacceptable emissions were measured at high load taking into account EURO VI limitations. Finally, the application of a mathematical function considering certain self-imposed constraints suggested that the more suitable piston geometry for RCCI operation is the stepped one, which has a modified transition from the center to the squish region and reduced piston surface area than the stock geometry

    Full Text Available In the mid-2000s, neonatal mortality accounted for almost 40% of deaths of children under 5 years worldwide, and constituted 65% of infant deaths in India. The neonatal mortality rate in Andhra Pradesh was 44 per 1,000 live births, and was higher in the rural areas and tribal regions, such as the Nagarkurnool division of Mahabubnagar district (which became Nagarkurnool district in Telangana in 2014. The aim of the CHAMPION trial was to investigate whether a package of interventions comprising community health promotion and provision of health services (including outreach and facility-based care could lead to a reduction of the order of 25% in neonatal mortality.The design was a trial in which villages (clusters in Nagarkurnool with a population < 2,500 were randomised to the CHAMPION package of health interventions or to the control arm (in which children aged 6-9 years were provided with educational interventions-the STRIPES trial. A woman was eligible for the CHAMPION package if she was married and <50 years old, neither she nor her husband had had a family planning operation, and she resided in a trial village at the time of a baseline survey before randomisation or married into the village after randomisation. The CHAMPION intervention package comprised community health promotion (including health education via village health worker-led participatory discussion groups and provision of health services (including outreach, with mobile teams providing antenatal check-ups, and facility-based care, with subsidised access to non-public health centres [NPHCs]. Villages were stratified by travel time to the nearest NPHC and tribal status, and randomised (1:1 within strata. The primary outcome was neonatal mortality. Secondary outcomes included maternal mortality, causes of death, health knowledge, health practices including health service usage, satisfaction with care, and costs.

    2010-01-01

    The present work investigates the effect of varying the combustion chamber geometry and engine rotational speed on the gas flow and temperature field, using a new quasi-dimensional engine simulation model in conjunction with an in-house developed computational fluid dynamics (CFD) code served to validate the predicted in-cylinder flow field and gas temperature distribution calculated by the quasi-dimensional model, for three alternative piston bowl geometries and three rotational speeds. This CFD code can simulate three-dimensional curvilinear domains using the finite volume method in a collocated grid; it solves the generalized transport equation for the conservation of mass, momentum and energy, and incorporates the standard k-ε turbulence model with some slight modifications to introduce the compressibility of a fluid in generalized coordinates. On the other hand, the quasi-dimensional model solves the general transport equation for the conservation of mass and energy by a finite volume method throughout the entire in-cylinder volume, while for the estimation of the flow field a new simplified three dimensional air motion model is used. To compare these two models the in-cylinder spatial and temporal temperature distribution, the mean cylinder pressure diagram, as well as the mean in-cylinder radial and axial velocity are examined, for the three piston bowl geometries and the three speeds, for a high speed direct injection (HSDI) diesel engine operating under motoring conditions. From the comparison of calculated results, it becomes apparent that the two models predict similar in-cylinder temperature distributions and mean air velocity fields at each crank angle, for all cases examined. Thus, it is shown that the quasi-dimensional model with the proposed simplified air motion model is capable of capturing the physical effect of combustion chamber geometry and speed on the in-cylinder velocity and temperature field, while needing significantly lower computing

    The Kings Bowl (KB) eruptive fissure and lava field, located in the southern end of Craters of the Moon National Monument, Idaho, is an ideal location for planetary analogue field studies of surface properties related to volcanic and impact processes. Here we look at possible impact features present in the KB lava field near the main vent that resulted in squeeze-ups of molten lava from beneath a semi-solid lava lake crust. These may have been caused by the ejection of blocks during the phreatic eruption that formed the Kings Bowl pit, and their subsequent impact into a partially solidified lava pond. We compare and contrast these features with analogous self-secondary impact features, such as irregular, rimless secondary craters ("splash craters") observed in lunar impact melt deposits, to better understand how self-secondary impacts determine the surface properties of volcanic and impact crater terrains. We do this by analyzing field measurements of these features, as well as high-resolution DEM data collected through the Kinematic LiDAR System (KLS), both of which give us feature dimensions and distributions. We then compare these data with self-secondary impact features on the Moon and related surface roughness constrained through Lunar Reconnaissance Orbiter observations (Mini-RF and LROC NACs). Possible self-secondary impact features can be found in association with many lunar impact craters. These are formed when ballistic ejecta from the crater falls onto the ejecta blanket and melt surrounding the newly formed crater. Self-secondary impact features involving impact melt deposits are particularly useful to study because the visibly smooth melt texture serves to highlight the impact points in spacecraft imagery. The unusual morphology of some of these features imply that they formed when the melt had not yet completely solidified, strongly suggesting a source of impactors from the primary crater itself. We will also discuss ongoing efforts to integrate field

  1. Middle-Out Approaches to Reform of University Teaching and Learning: Champions striding between the top-down and bottom-up approaches

    2005-03-01

    Full Text Available In recent years, Australian universities have been driven by a diversity of external forces, including funding cuts, massification of higher education, and changing student demographics, to reform their relationship with students and improve teaching and learning, particularly for those studying off-campus or part-time. Many universities have responded to these forces either through formal strategic plans developed top-down by executive staff or through organic developments arising from staff in a bottom-up approach. By contrast, much of Murdoch University’s response has been led by a small number of staff who have middle management responsibilities and who have championed the reform of key university functions, largely in spite of current policy or accepted practice. This paper argues that the ‘middle-out’ strategy has both a basis in change management theory and practice, and a number of strengths, including low risk, low cost, and high sustainability. Three linked examples of middle-out change management in teaching and learning at Murdoch University are described and the outcomes analyzed to demonstrate the benefits and pitfalls of this approach.

    2012-09-13

    As a national security science laboratory, Los Alamos is often asked to detect and measure the characteristics of complex systems and to use the resulting information to quantify the system's behavior. The Science of Signatures (SoS) pillar is the broad suite of technical expertise and capability that we use to accomplish this task. With it, we discover new signatures, develop new methods for detecting or measuring signatures, and deploy new detection technologies. The breadth of work at Los Alamos National Laboratory (LANL) in SoS is impressive and spans from the initial understanding of nuclear weapon performance during the Manhattan Project, to unraveling the human genome, to deploying laser spectroscopy instrumentation on Mars. Clearly, SoS is a primary science area for the Laboratory and we foresee that as it matures, new regimes of signatures will be discovered and new ways of extracting information from existing data streams will be developed. These advances will in turn drive the development of sensing instrumentation and sensor deployment. The Science of Signatures is one of three science pillars championed by the Laboratory and vital to supporting our status as a leading national security science laboratory. As with the other two pillars, Materials for the Future and Information Science and Technology for Predictive Science (IS&T), SoS relies on the integration of technical disciplines and the multidisciplinary science and engineering that is our hallmark to tackle the most difficult national security challenges. Over nine months in 2011 and 2012, a team of science leaders from across the Laboratory has worked to develop a SoS strategy that positions us for the future. The crafting of this strategy has been championed by the Chemistry, Life, and Earth Sciences Directorate, but as you will see from this document, SoS is truly an Institution-wide effort and it has engagement from every organization at the Laboratory. This process tapped the insight and

    Highlights: • Effect of injection rate-shaping on heat-release is significant with less turbulence. • Two peak heat-releases are seen for the shallow-depth re-entrant piston. • Significant combustion phasing occurs with kerosene usage and high turbulence. - Abstract: In this work, the combustion characteristics of a direct injection compression ignition (DICI) engine fueled with kerosene-diesel blends, using different piston bowl geometries together with varying injection rate-shapes were investigated. A total of three combustion bowl geometries, namely the omega combustion chamber (OCC), the shallow-depth combustion chamber (SCC) and the shallow-depth re-entrant combustion chamber (SRCC), were used together with six different ramp injection rate-shapes and pure diesel, kerosene-diesel and pure kerosene fuels. It is seen that the SRCC geometry, which has the shortest throat length, gives the highest turbulence kinetic energy (TKE) and this resulted in two peak heat-releases, with a primary peak heat-release during the premixed combustion phase and a secondary peak heat-release during the mixing-controlled combustion phase. In addition, the SCC geometry gives rather distinct premixed combustion and mixing-controlled combustion phases due to the fact that combustion is predominantly controlled by the injected fuel spray itself because of less turbulence. Also, when kerosene is used in place of diesel, the heat-release during the premixed combustion phase increases and diminishes during the mixing-controlled and late combustion phases. It is interesting to note that the effect of injection rate-shaping on the heat-release rate is more obvious for bowl geometries that generate less TKE. Moreover, bowl geometries that generate higher TKEs as well as fuels with lower viscosities generally give lower carbon monoxide (CO) emissions and higher nitrogen oxide (NO) emissions. More importantly, it is possible to achieve low NO and CO emissions simultaneously by using the

  4. Defining science literacy: A pedagogical approach

    Brilakis, Kathryn

    A functional knowledge of science is required to capably evaluate the validity of conflicting positions on topics such as fracking, climate change, and the safety of genetically modified food. Scientifically illiterate individuals are at risk of favoring the persuasive arguments of those championing partisan, anti-science agendas. In an effort to enhance the scientific literacy of community college students and equip them with the skill set necessary to make informed decisions, this study generated a pedagogical definition of science literacy using survey methodology and then utilized the definition to construct an accessible, comprehensive, and pragmatic web-based science literacy program. In response to an email solicitation, college and university science educators submitted lists of topics within their specialty they considered essential when assessing science literacy. Their responses were tabulated and those topics cited most frequently by the participating physicists, biologists, chemists and geoscientists were assembled into a definition of science literacy. This definition was translated into a modular, web-based course suitable for both online and classroom learning published as: www.scienceliteracyforum.com.

    Game theory is central to understanding human behavior and relevant to all of the behavioral sciences-from biology and economics, to anthropology and political science. However, as The Bounds of Reason demonstrates, game theory alone cannot fully explain human behavior and should instead complement other key concepts championed by the behavioral disciplines. Herbert Gintis shows that just as game theory without broader social theory is merely technical bravado, so social theory without game theory is a handicapped enterprise.

    Full Text Available The coordination of body movements to a musical beat is a common feature of many dance styles. However, the auditory-motor coordination skills of dancers remain largely uninvestigated. The purpose of this study was to examine the auditory-motor coordination skills of non-dancers, street dancers, and the winner of a celebrated international street dance competition, while coordinating their rhythmic finger movements to a beat. The beat rate of a metronome increased from 1.0 to 3.7 Hz. The participants were asked to either flex or extend their index fingers on the beat in each condition. Under the extend-on-the-beat condition, both the dancers and non-dancers showed a spontaneous transition from the extend-on-the-beat to the flex-on-the-beat or to a phase wandering pattern. However, the critical frequency at which the transition occurred was significantly higher in the dancers (3.3 Hz than in the non-dancers (2.6 Hz. Under the flex-on-the-beat condition, the dancers were able to maintain their coordination pattern more stably at high beat rates compared to the non-dancers. Furthermore, the world champion matched the timing of movement peak velocity to the beat across the different beat rates. This may give a sense of unity between the movement and the beat for the audience because the peak velocity of the rhythmic movement works as a temporal cue for the audiovisual synchrony perception. These results suggest that the skills of accomplished dancers lie in their small finger movements and that the sensorimotor learning of street dance is characterized by a stabilization of the coordination patterns, including the inhibition of an unintentional transition to other coordination patterns.

    Organizational effectiveness and the continuity of patient care can be affected by certain levels of attrition. However, little is known about the retention and attrition of female certified athletic trainers (ATs) in certain settings. To gain insight and understanding into the factors and circumstances affecting female ATs' decisions to persist in or leave the National Collegiate Athletic Association Division I Football Bowl Subdivision (NCAA D-I FBS) setting. Qualitative study. The 12 NCAA D-I FBS institutions within the Southeastern Conference. A total of 23 women who were current full-time ATs (n = 12) or former full-time ATs (n = 11) at Southeastern Conference institutions participated. Data were collected via in-depth, semistructured interviews, transcribed verbatim, and analyzed via a grounded theory approach. Peer review and member checking methods were performed to establish trustworthiness. The decision to persist involved 4 main factors: (1) increased autonomy, (2) increased social support, (3) enjoyment of job/fitting the NCAA D-I mold, and (4) kinship responsibility. Two subfactors of persistence, the NCAA D-I atmosphere and positive athlete dynamics, emerged under the main factor of enjoyment of job/fitting the NCAA D-I mold. The decision to leave included 3 main factors: (1) life balance issues, (2) role conflict and role overload, and (3) kinship responsibility. Two subfactors of leaving, supervisory/coach conflict and decreased autonomy, emerged under the main factor of role conflict and role overload. A female AT's decision to persist in or leave the NCAA D-I FBS setting can involve several factors. In order to retain capable ATs long term in the NCAA D-I setting, an individual's attributes and obligations, the setting's cultural issues, and an organization's social support paradigm should be considered.

  9. Finding Meaningful Roles for Scientists in science Education Reform

    Science.gov (United States)

    Evans, Brenda

    Successful efforts to achieve reform in science education require the active and purposeful engagement of professional scientists. Working as partners with teachers, school administrators, science educators, parents, and other stakeholders, scientists can make important contributions to the improvement of science teaching and learning in pre-college classrooms. The world of a practicing university, corporate, or government scientist may seem far removed from that of students in an elementary classroom. However, the science knowledge and understanding of all future scientists and scientifically literate citizens begin with their introduction to scientific concepts and phenomena in childhood and the early grades. Science education is the responsibility of the entire scientific community and is not solely the responsibility of teachers and other professional educators. Scientists can serve many roles in science education reform including the following: (1) Science Content Resource, (2) Career Role Model, (3) Interpreter of Science (4) Validator for the Importance of Learning Science and Mathematics, (5) Champion of Real World Connections and Value of Science, (6) Experience and Access to Funding Sources, (7) Link for Community and Business Support, (8) Political Supporter. Special programs have been developed to assist scientists and engineers to be effective partners and advocates of science education reform. We will discuss the rationale, organization, and results of some of these partnership development programs.

    Siemens announced in January 26, 2009 its decision to leave Areva NP, i.e. the Areva/Siemens common daughter company for reactors. This news re-launches the questions about the long-term financing strategy of the Areva group, of its capitalistic partnerships and of its position in the world nuclear market. Siemens on its side wishes to preserve its position in this market and a possible cooperation with the Russian AtomEnergoProm is under discussion. Areva, the world leader of nuclear industry, integrates a mining activity as well and is the world number 3 of uranium exploitation (15% of the world offer). It wishes to double its production by 2012 thanks to big investments in Niger, Namibia and Canada. Areva is developing its enrichment capacities as well thanks to the future Georges-Besse II ultracentrifugation facility which is under construction at Tricastin (Drome, France) and which should be put into service in 2009. And finally, a second EPR (European pressurized reactor), the new generation of Areva reactors, is to be built at Penly (Haute Normandie, France) between 2012 and 2017 and will generate 1400 employments in the region.

    Cangrelor is an intravenous P2Y12 inhibitor approved to reduce periprocedural ischemic events in patients undergoing percutaneous coronary intervention not pretreated with a P2Y12 inhibitor. A total of 11 145 patients were randomized to cangrelor or clopidogrel in the CHAMPION PHOENIX trial (Cangrelor versus Standard Therapy to Achieve Optimal Management of Platelet Inhibition). We explored the effects of cangrelor on myocardial infarction (MI) using different definitions and performed sensitivity analyses on the primary end point of the trial. A total of 462 patients (4.2%) undergoing percutaneous coronary intervention had an MI as defined by the second universal definition. The majority of these MIs (n=433, 93.7%) were type 4a. Treatment with cangrelor reduced the incidence of MI at 48 hours (3.8% versus 4.7%; odds ratio [OR], 0.80; 95% confidence interval [CI], 0.67-0.97; P=0.02). When the Society of Coronary Angiography and Intervention definition of periprocedural MI was applied to potential ischemic events, there were fewer total MIs (n=134); however, the effects of cangrelor on MI remained significant (OR, 0.65; 95% CI, 0.46-0.92; P=0.01). Similar effects were seen in the evaluation of the effects of cangrelor on MIs with peak creatinine kinase-MB ≥10 times the upper limit of normal (OR, 0.64; 95% CI, 0.45-0.91) and those with peak creatinine kinase-MB ≥10 times the upper limit of normal, ischemic symptoms, or ECG changes (OR, 0.63; 95% CI, 0.48-0.84). MIs defined by any of these definitions were associated with increased risk of death at 30 days. Treatment with cangrelor reduced the composite end point of death, MI (Society of Coronary Angiography and Intervention definition), ischemia-driven revascularization, or Academic Research Consortium definite stent thrombosis (1.4% versus 2.1%; OR, 0.69; 95% CI, 0.51-0.92). MI in patients undergoing percutaneous coronary intervention, regardless of definition, remains associated with increased risk of death

  13. Nature of Bonding in Bowl-Like B36 Cluster Revisited: Concentric (6π+18π) Double Aromaticity and Reason for the Preference of a Hexagonal Hole in a Central Location.

    2018-05-04

    The bowl-shaped C 6v B 36 cluster with a central hexagon hole is considered an ideal molecular model for low-dimensional boron-based nanosystems. Owing to the electron deficiency of boron, chemical bonding in the B 36 cluster is intriguing, complicated, and has remained elusive despite a couple of papers in the literature. Herein, a bonding analysis is given through canonical molecular orbitals (CMOs) and adaptive natural density partitioning (AdNDP), further aided by natural bond orbital (NBO) analysis and orbital composition calculations. The concerted computational data establish the idea of concentric double π aromaticity for the B 36 cluster, with inner 6π and outer 18π electron counting, which both conform to the (4n+2) Hückel rule. The updated bonding picture differs from existing knowledge of the system. A refined bonding model is also proposed for coronene, of which the B 36 cluster is an inorganic analogue. It is further shown that concentric double π aromaticity in the B 36 cluster is retained and spatially fixed, irrespective of the migration of the hexagonal hole; the latter process changes the system energetically. The hexagonal hole is a destabilizing factor for σ/π CMOs. The central hexagon hole affects substantially fewer CMOs, thus making the bowl-shaped C 6v B 36 cluster the global minimum. © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Hiebert, Erwin N.

    The physicist Franz Serafin Exner (1849-1926) was a prominent Austrian spokesman for the new developments that were coupled with turn-of-the-century experiments and theories related to entropy thermodynamics, the internally structured atom, quantum theory, and relativity. The Exner circle found its inspiration in the intellectual world of Ludwig Boltzmann and his teachers, colleagues, and students. Cross-discipline discussions on common and divergent frontiers of the exact sciences and the humanities meaningfully converged on the significance, comparison, and transfer of concepts such as the laws of nature, causality, probability, and chance. Oswald Spengler's Decline of the West, with its pessimistic, subjectivistic, and negative science-directed messages provided Exner with the opportunity to sharpen his support for the new scientific trends in physics - thus to champion the search for objective truth.

    In 2012, Makerere University Johns - Hopkins University, and Mulago National Referral Hospital, with support from the National Institute of Health (under Grant number: NOT AI-01-023) undertook operational research at Mulago National Hospital PMTCT/PNC clinics. The study employed Peer Family Planning Champions to offer health education, counselling, and triage aimed at increasing the identification, referral and family planning (FP) uptake among HIV positive mothers attending the clinic. The Peer Champion Intervention to improve FP uptake was introduced into Mulago Hospital PMTCT/PNC clinic, Kampala Uganda. During the intervention period, peers provided additional FP counselling and education; assisted in identification and referral of HIV Positive mothers in need of FP services; and accompanied referred mothers to FP clinics. We compiled and compared the average proportions of mothers in need that were referred and took up FP in the pre-intervention (3 months), intervention (6 months), and post-intervention(3 months) periods using interrupted time series with segmented regression models with an autoregressive term of one. Overall, during the intervention, the proportion of referred mothers in need of FP increased by 30.4 percentage points (P family planning can be a valuable addition to clinic staff in limited-resource settings. The study provides additional evidence on the utilization of peer mothers in HIV care, improves health services uptake including family planning which is a common practice in many donor supported programs. It also provides evidence that may be used to advocate for policy revisions in low-income countries to include peers as support staff especially in busy clinic settings with poor services uptake.

    The FINESSE (Field Investigations to Enable Solar System Science and Exploration) team is focused on a science and exploration field-based research program aimed at generating strategic knowledge in preparation for the human and robotic exploration of the Moon, near-Earth asteroids (NEAs) and Phobos and Deimos. We follow the philosophy that "science enables exploration and exploration enables science." 1) FINESSE Science: Understand the effects of volcanism and impacts as dominant planetary processes on the Moon, NEAs, and Phobos & Deimos. 2) FINESSE Exploration: Understand which exploration concepts of operations (ConOps) and capabilities enable and enhance scientific return. To accomplish these objectives, we are conducting an integrated research program focused on scientifically-driven field exploration at Craters of the Moon National Monument and Preserve in Idaho and at the West Clearwater Lake Impact Structure in northern Canada. Field deployments aimed at reconnaissance geology and data acquisition were conducted in 2014 at Craters of the Moon National Monument and Preserve. Targets for data acquisition included selected sites at Kings Bowl eruptive fissure, lava field and blowout crater, Inferno Chasm vent and outflow channel, North Crater lava flow and Highway lava flow. Field investigation included (1) differential GPS (dGPS) measurements of lava flows, channels (and ejecta block at Kings Bowl); (2) LiDAR imaging of lava flow margins, surfaces and other selected features; (3) digital photographic documentation; (4) sampling for geochemical and petrographic analysis; (5) UAV aerial imagery of Kings Bowl and Inferno Chasm features; and (6) geologic assessment of targets and potential new targets. Over the course of the 5-week field FINESSE campaign to the West Clearwater Impact Structure (WCIS) in 2014, the team focused on several WCIS research topics, including impactites, central uplift formation, the impact-generated hydrothermal system, multichronometer

    The Earth Science Women's Network (ESWN) began informally in 2002 as a way for six early career female atmospheric chemists to stay in contact and support each other. Twelve years later (2014), the ESWN formally became a non-profit organization with over 2000 members. The ESWN includes scientists from all disciplines of the geosciences with members located in over 50 countries. The ESWN is dedicated to career development, peer mentoring and community building for women in the geosciences. The mentoring philosophy of ESWN has evolved to include five main principles: 1.) Support community-driven mentoring, 2.) Encourage diverse mentoring approaches for diverse individuals, 3.) Facilitate mentoring across career phases, 4.) Promote combined personal and professional mentoring, 5.) Champion effective mentoring in a safe space. Surveys of ESWN members report gains in areas that are often considered barriers to career advancement, including recognition that they are not alone, new understanding of obstacles faced by women in science, and access to professional resources.

  15. Developing science policy capacity at the state government level: Planning a science and technology policy fellowship program for Colorado and beyond

    Science.gov (United States)

    Druckenmiller, M. L.

    2017-12-01

    There is growing recognition of the potential to advance science policy capacity within state legislatures, where there is most often a shortage of professional backgrounds in the natural sciences, technology, engineering, and medicine. Developing such capacity at the state level should be considered a vital component of any comprehensive national scale strategy to strengthen science informed governance. Toward this goal, the Center for Science and Technology Policy Research at the University of Colorado Boulder is leading a strategic planning process for a Science and Technology Policy Fellowship Program within the Colorado state legislature and executive branch agencies. The intended program will place PhD-level scientists and engineers in one-year placements with decision-makers to provide an in-house resource for targeted policy-relevant research. Fellows will learn the intricacies of the state policymaking process, be exposed to opportunities for science to inform decisions, and develop a deeper understanding of key science and technology topics in Colorado, including water resources, wildfire management, and energy. The program's ultimate goals are to help foster a decision-making arena informed by evidence-based information, to develop new leaders adept at bridging science and policymaking realms, and to foster governance that champions the role of science in society. Parallel to efforts in Colorado, groups from nine other states are preparing similar plans, providing opportunities to share approaches across states and to set the stage for increased science and technology input to state legislative agendas nationwide. Importantly, highly successful and sustainable models exist; the American Association for the Advancement of Science (AAAS) has implemented a federally based fellowship program for over 43 years and the California Council for Science and Technology (CCST) has directed a fellowship program for their state's legislature since 2009.

    The field of planetary science as it developed during the lifetimes of Gene and Carolyn Shoemaker has sustained a period of exciting growth. Surveying the skies for planet-crossing asteroids and comets and studying the results of their impact upon the planets, especially the Earth, was for Gene and Carolyn an intense and satisfying quest for knowledge. It all started when Gene envisioned man going to the Moon, especially himself. After that, one thing led to another: the study of nuclear craters and a comparison with Meteor Crater, Arizona; the Apollo project and a succession of unmanned space missions to the inner and outer planets; an awareness of cratering throughout our solar system; the search for near-Earth asteroids and comets; a study of ancient craters in Australia; and the impact of Shoemaker-Levy 9 on Jupiter. The new paradigm of impact cratering as a cause for mass extinction and the opening of space for the development of new life forms have been causes to champion.

    Energy dispersive X-ray fluorescence (EDXRF) is a well-known technique for non-destructive and in situ analysis of archaeological artifacts both in terms of the qualitative and quantitative elemental composition because of its rapidity and non-destructiveness. In this study EDXRF and realistic Monte Carlo simulation using the X-ray Monte Carlo (XRMC) code package have been combined to characterize a Cu-based bowl from the Iron Age burial from Fareleira 3 (Southern Portugal). The artifact displays a multilayered structure made up of three distinct layers: a) alloy substrate; b) green oxidized corrosion patina; and c) brownish carbonate soil-derived crust. To assess the reliability of Monte Carlo simulation in reproducing the composition of the bulk metal of the objects without recurring to potentially damaging patina's and crust's removal, portable EDXRF analysis was performed on cleaned and patina/crust coated areas of the artifact. Patina has been characterized by micro X-ray Diffractometry (μXRD) and Back-Scattered Scanning Electron Microscopy + Energy Dispersive Spectroscopy (BSEM + EDS). Results indicate that the EDXRF/Monte Carlo protocol is well suited when a two-layered model is considered, whereas in areas where the patina + crust surface coating is too thick, X-rays from the alloy substrate are not able to exit the sample. - Highlights: • EDXRF/Monte Carlo simulation is used to characterize an archeological alloy. • EDXRF analysis was performed on cleaned and patina coated areas of the artifact. • EDXRF/Montes Carlo protocol is well suited when a two-layered model is considered. • When the patina is too thick, X-rays from substrate are unable to exit the sample.

    Full Text Available The Museo Nacional de Artes Decorativas (Madrid has a beautiful glass bowl decorated with coloured drops, which has never been studied. This was a very popular type of glassware all over the Roman world, especially in Gaul and the Rhineland, but also in other Roman provinces. Numerous pieces were manufactured with this design and occasionally they were also copied in large series of lower quality to satisfy the mass market. In the twentieth century, few vases of this type were known in Spain and they had not been studied in depth, so they were considered luxury imports. However, recent excavations and studies have verified that they were also very common in Hispania in the fourth and fifth centuries A.D. | La colección de vidrios romanos del Museo Nacional de Artes Decorativas posee un vaso decorado con cabujones de colores que nunca ha sido debidamente publicado.

En el siglo XX eran escasos los vasos españoles conocidos de esta clase y no estaban bien estudiados, por lo que se consideraban piezas importadas de lujo. En los últimos años, recientes excavaciones y estudios han evidenciado que fueron piezas corrientes en las vajillas de Hispania durante los siglos IV-V d.C.

    A 62-year-old Japanese man, a bronze medal winner in the World Championship of table tennis when in his 20s, was diagnosed with secondary adrenocortical insufficiency due to isolated adrenocorticotropic hormone (ACTH) deficiency, and steroid administration was started. About 1 year after the diagnosis, he took part in a table tennis championship which was open to those 40 years or older. He took 10 mg hydrocortisone after breakfast as usual, played 10 matches, each of which took 20–30 min, and won the championship in about 8 h. Since the man could not always win the gruelling competition even when in his 50s, it is suggested that extra steroid hormone is not necessary for patients with adrenocortical insufficiency due to ACTH deficiency in order to successfully engage in sports requiring such intensity and endurance.

    The authors find overwhelming evidence among environmental health practitioners that One Health disease reporting concepts are essential to the early detection of, and expedient recovery from, pandemic disease events. The authors also find, however, extraordinary evidence that local public health is not prepared, and potentially unaware of their responsibility, to be the initiator of the zoonotic infectious disease information intelligence necessary to make such early event mitigation possible. The authors propose that NEHA take an affirmative step towards the development of local public health-initiated biosurveillance systems by organizing and leading a tabletop study group that includes the Centers for Disease Control and Prevention, American Veterinary Medical Association, American Medical Association, Food and Drug Administration, U.S. Department of Agriculture, Institute of Medicine, and a robust panel of NEHA state affiliates. This study group should discuss the infrastructure necessary for local public health-the frontline against community-acquired infectious disease-to be the initiators of environmental health, veterinary, and medical One Health biosurveillance systems. The need to establish a community-focused, integrated disease prevention strategy that cautions people about the risks associated with food, water, animal, and contaminated environmental media, both prior to and during epidemic and pandemic events is equally important.

  11. Medicine as a Social Political Science : The Case of Spain c. 1920

    Directory of Open Access Journals (Sweden)

    Rodríguez-Ocaña, Esteban

    2007-12-01

    Full Text Available This paper discusses the Spanish contribution to the forming of Social Medicine, as a particular understanding of the relationship between health and society that eventually became a formal discipline, as a variant of Public Health. It focuses on two questions, first the literary tradition linking Social Sciences and Medicine, and the forming of the key concept of “social disease”; and, second, on the nature and aims of the inter-professional groups that championed this process. If during centuries, medical concepts had been used to explain social life, around the time of the First World War, doctors started to explain medical matters in social terms, in order to both reinforce their monopoly and offer a kind of solutions to social evils suited to the new professional middle classes. Massive programmes of prevention and care were applied as a receipt against severe social unrest, developing a trend of long lasting influence.

    The stage I uterine malignant mixed mullerian tumor (MMMT) shows different potential for progression. We reason that MMMTs with high-grade carcinomatous component and positivity for HB-EGF are prone to recurrence/metastasis in the early stage. A retrospective clinical and histopathologic review with immunohistochemical staining for HB-EGF, EGFR, and integrin-α5 was performed for 62 surgically staged MMMT cases. Recurrence/metastasis (RM) is 6/18 (33%) in stage I disease. Of all the clinicopathologic variables and biomarkers analyzed for stage I MMMT, serous carcinomatous component (83% [5/6] versus 17% [1/12], P = .0015) and HB-EGF expression (100% [6/6] versus 50% [6/12], P=.0339) were significantly different between groups with RM and without RM. The presence of serous carcinoma in all stages was 83% (5/6) in stage I with RM, 8% (1/12) in stage I without RM, 20% (1/5) in stage II, 36.4% (8/22) in stage III and 64.7% (11/17) in stage IV; this was paralleled by HB-EGF expression of 100% (6/6), 50% (6/12), 40% (2/5), 50% (11/22) and 71% (12/17) with a correlation coefficient r=0.9131 (P=.027). HB-EGF and integrin-α5 were highly expressed in MMMTs bearing serous carcinoma component, compared to endometrioid and unclassifiable/miscellaneous subtypes (84.6%/47.6%/33.3%, P=.025 for HB-EGF; and 61.5%/42.9%/20.0%, P=.021 for integrin-α5). The EGFR positivity was comparable among the three subtypes (48.1%, 47.6% and 26.7%, P=.326). This study indicates that serous carcinomatous component championed by expression of HB-EGF predisposes to recurrence/metastasis in stage I MMMT. This process might involve integrin-α5 and does not seem to require overexpression of EGFR. Further study is required. Published by Elsevier Inc.

  17. Key Features of Governance in Brazilian Science and Technology Parks

    Full Text Available The situation of Brazilian Science and Technology Parks (STPs operation led to the field research. Even with the public policy of stimulus and support of associations, nothing has been mapped on the dissemination of results (economic growth and regional development. This scenario instigates the question: What are the governance characteristics of Brazilian Science and Technology Parks? A empirical field research was developed, taking into consideration the possibility of replication trought the registration of the choice criteria in the multiple cases and trought research detalhes and data colection. Eight STPs (TECNOPUC - Porto Alegre, Valetec - Novo Hamburgo, Tecnosinos - Sao Leopoldo, Unicamp, CIATEC and TECHNOPARK - Campinas, Rio Park - Rio de Janeiro and SergipeTec participated in research. The results and considerations about the research question allows to infer the little effectiveness of governance (without qualitative or quantitative performance indicators is possibly caused by tensions characterized by elements such as heterogeneity in characteristics of organizations that are part of STPs, lack of consensus on common goals, pressure forces and influences affecting trusts, nonconformity standards and personal and organizational preferences. Leadership relations championed by the government and / or companies can negatively influence the STP's performance as a whole.

    In this paper I expand on the premises of Jesse Bazzul's thesis in his paper, Neoliberal ideology, global capitalism, and science education: engaging the question of subjectivity, exploring the implications of the ideologies within the culturally emerging logic of science exposes the incommensurability of intents and purposes in its methods and epistemology. I argue that science needs to acknowledge the subjectivity at its core to make space for non-absolute agents and new fields of study.

  9. Science teaching in science education

    Callahan, Brendan E.; Dopico, Eduardo

    2016-06-01

    Reading the interesting article Discerning selective traditions in science education by Per Sund , which is published in this issue of CSSE, allows us to open the discussion on procedures for teaching science today. Clearly there is overlap between the teaching of science and other areas of knowledge. However, we must constantly develop new methods to teach and differentiate between science education and teaching science in response to the changing needs of our students, and we must analyze what role teachers and teacher educators play in both. We must continually examine the methods and concepts involved in developing pedagogical content knowledge in science teachers. Otherwise, the possibility that these routines, based on subjective traditions, prevent emerging processes of educational innovation. Modern science is an enormous field of knowledge in its own right, which is made more expansive when examined within the context of its place in society. We propose the need to design educative interactions around situations that involve science and society. Science education must provide students with all four dimensions of the cognitive process: factual knowledge, conceptual knowledge, procedural knowledge, and metacognitive knowledge. We can observe in classrooms at all levels of education that students understand the concepts better when they have the opportunity to apply the scientific knowledge in a personally relevant way. When students find value in practical exercises and they are provided opportunities to reinterpret their experiences, greater learning gains are achieved. In this sense, a key aspect of educational innovation is the change in teaching methodology. We need new tools to respond to new problems. A shift in teacher education is needed to realize the rewards of situating science questions in a societal context and opening classroom doors to active methodologies in science education to promote meaningful learning through meaningful teaching.

  10. Revolutionary Science.

    Science.gov (United States)

    Casadevall, Arturo; Fang, Ferric C

    2016-03-01

    On rare occasions in the history of science, remarkable discoveries transform human society and forever alter mankind's view of the world. Examples of such discoveries include the heliocentric theory, Newtonian physics, the germ theory of disease, quantum theory, plate tectonics and the discovery that DNA carries genetic information. The science philosopher Thomas Kuhn famously described science as long periods of normality punctuated by times of crisis, when anomalous observations culminate in revolutionary changes that replace one paradigm with another. This essay examines several transformative discoveries in the light of Kuhn's formulation. We find that each scientific revolution is unique, with disparate origins that may include puzzle solving, serendipity, inspiration, or a convergence of disparate observations. The causes of revolutionary science are varied and lack an obvious common structure. Moreover, it can be difficult to draw a clear distinction between so-called normal and revolutionary science. Revolutionary discoveries often emerge from basic science and are critically dependent on nonrevolutionary research. Revolutionary discoveries may be conceptual or technological in nature, lead to the creation of new fields, and have a lasting impact on many fields in addition to the field from which they emerge. In contrast to political revolutions, scientific revolutions do not necessarily require the destruction of the previous order. For humanity to continue to benefit from revolutionary discoveries, a broad palette of scientific inquiry with a particular emphasis on basic science should be supported.

    Primary science teachers in Scotland have a new updating method at their disposal with the launch of a package of CDi (Compact Discs Interactive) materials developed by the BBC and the Scottish Office. These were a response to the claim that many primary teachers felt they had been inadequately trained in science and lacked the confidence to teach it properly. Consequently they felt the need for more in-service training to equip them with the personal understanding required. The pack contains five disks and a printed user's guide divided up as follows: disk 1 Investigations; disk 2 Developing understanding; disks 3,4,5 Primary Science staff development videos. It was produced by the Scottish Interactive Technology Centre (Moray House Institute) and is available from BBC Education at £149.99 including VAT. Free Internet distribution of science education materials has also begun as part of the Global Schoolhouse (GSH) scheme. The US National Science Teachers' Association (NSTA) and Microsoft Corporation are making available field-tested comprehensive curriculum material including 'Micro-units' on more than 80 topics in biology, chemistry, earth and space science and physics. The latter are the work of the Scope, Sequence and Coordination of High School Science project, which can be found at http://www.gsh.org/NSTA_SSandC/.

  5. Is normal science good science?

    Directory of Open Access Journals (Sweden)

    Adrianna Kępińska

    2015-09-01

    Full Text Available “Normal science” is a concept introduced by Thomas Kuhn in The Structure of Scientific Revolutions (1962. In Kuhn’s view, normal science means “puzzle solving”, solving problems within the paradigm—framework most successful in solving current major scientific problems—rather than producing major novelties. This paper examines Kuhnian and Popperian accounts of normal science and their criticisms to assess if normal science is good. The advantage of normal science according to Kuhn was “psychological”: subjective satisfaction from successful “puzzle solving”. Popper argues for an “intellectual” science, one that consistently refutes conjectures (hypotheses and offers new ideas rather than focus on personal advantages. His account is criticized as too impersonal and idealistic. Feyerabend’s perspective seems more balanced; he argues for a community that would introduce new ideas, defend old ones, and enable scientists to develop in line with their subjective preferences. The paper concludes that normal science has no one clear-cut set of criteria encompassing its meaning and enabling clear assessment.

    How does Einstein’s description of space and time compare with Dr. Who? Can James Bond really escape from an armor-plated railroad car by cutting through the floor with a laser concealed in a wristwatch? What would it take to create a fully-intelligent android, such as Star Trek’s Commander Data? How might we discover intelligent civilizations on other planets in the galaxy? Is human teleportation possible? Will our technological society ever reach the point at which it becomes lawful to discriminate on the basis of genetic information, as in the movie GATTACA? Exploring Science Through Science Fiction addresses these and other interesting questions, using science fiction as a springboard for discussing fundamental science concepts and cutting-edge science research. The book is designed as a primary text for a college-level course which should appeal to students in the fine arts and humanities as well as to science and engineering students. It includes references to original research papers, landmark scie...

  7. Pure Science and Applied Science

    Directory of Open Access Journals (Sweden)

    Robert J. Aumann

    2011-01-01

    Full Text Available (Excerpt The name of my talk is Pure Science and Applied Science, and the idea I would like to sell to you today is that there is no such thing as “pure” or “applied” science. In other words, there is such a thing as science, but there is no difference between pure and applied science. Science is one entity and cannot be separated into different categories. In order to back that up, I would like to tell you a little story. As an undergraduate, I studied mathematics at City College in New York. At that time, what was called Pure Mathematics was in vogue, and the more prominent mathematicians were a little contemptuous of any kind of application. A very famous, prominent mathematician in the first half of the previous century by the name of G. H. Hardy, who was in a branch of mathematics called number theory, said that the only thing he regretted was that he unwittingly did some important work in mathematical genetics that eventually turned out to have some application. … Such was the atmosphere in the late ’40s of the previous century and, being a young man and impressionable, I was swept up in this atmosphere.

  8. The field of medical anthropology in Social Science & Medicine.

    Science.gov (United States)

    Panter-Brick, Catherine; Eggerman, Mark

    2018-01-01

    Conceptually and methodologically, medical anthropology is well-positioned to support a "big-tent" research agenda on health and society. It fosters approaches to social and structural models of health and wellbeing in ways that are critically reflective, cross-cultural, people-centered, and transdisciplinary. In this review article, we showcase these four main characteristics of the field, as featured in Social Science & Medicine over the last fifty years, highlighting their relevance for an international and interdisciplinary readership. First, the practice of critical inquiry in ethnographies of health offers a deep appreciation of sociocultural viewpoints when recording and interpreting lived experiences and contested social worlds. Second, medical anthropology champions cross-cultural breadth: it makes explicit local understandings of health experiences across different settings, using a fine-grained, comparative approach to develop a stronger global platform for the analysis of health-related concerns. Third, in offering people-centered views of the world, anthropology extends the reach of critical enquiry to the lived experiences of hard-to-reach population groups, their structural vulnerabilities, and social agency. Finally, in developing research at the nexus of cultures, societies, biologies, and health, medical anthropologists generate new, transdisciplinary conversations on the body, mind, person, community, environment, prevention, and therapy. As featured in this journal, scholarly contributions in medical anthropology seek to debate human health and wellbeing from many angles, pushing forward methodology, social theory, and health-related practice.

  9. Imagine the Feeling: An Aesthetic Science of Psychology.

    Science.gov (United States)

    Quigua, Fernando; Clegg, Joshua W

    2015-09-01

    We claim that static trait models have dominated contemporary personality psychology but fail to reflect adequately the persons they depict. Beginning from, but moving well beyond, this critique of the five factor model (and the personality psychology field over which it reigns), we shine an aesthetic and critical light on psychology's wider failings. We review the linguistic and methodological features that have undermined the discipline's faithful understandings of human beings and their experience. In its place, we champion an aesthetic (as opposed to an an-esthetic) science of the person, one that is responsive in spirit and in practice to the emotional and imaginative life of participants and to the contexts in which they move. Specifically, we suggest that the images of fantasy and of ordinary metaphor may afford poetic understandings of participant experience that surpass those produced by literal, discursive description. We also hold that these images may offer us the most sensitive and faithful expressions of how social and environmental contexts-and so-called structural and discursive realities-are felt. The paper concludes by sketching several methodological trajectories that may stimulate researcher imagination and empathy, making research more faithful to participants and the reaches of their experience. Research practices informed by feeling and image in this way may generate new knowledge as well as new obligations.

    The use of adhesives is widespread and growing, and there are few modern artefacts, from the simple cereal packet, to the jumbo jet, that are without this means of joining. Adhesion Science provides an illuminating account of the science underlying the use of adhesives, a branch of chemical technology which is fundamental to the science of coatings and composite materials and to the performance of all types of bonded structures. This book guides the reader through the essential basic polymer science, and the chemistry of adhesives in use at present. It discusses surface preparation for adhesive bonding, and the use of primers and coupling agents. There is a detailed chapter on contact angles and what can be predicted from them. A simple guide on stress distribution joints and how this relates to testing is included. It also examines the interaction of adhesives and the environment, including an analysis of the resistance of joints to water, oxygen and ultra-violet light.

    2011-07-01

    The Animal Sciences Academic Quadrathlon (AQ) provides opportunities for teams of undergraduate animal and dairy science students to participate in regional American Society of Animal Science (ASAS)/American Dairy Science Association (ADSA) meetings and to collectively exhibit their knowledge and talents competitively in 4 categories: 1) solving practical, hands-on, laboratory-type problems; 2) providing written answers to essay-type questions about principles and concepts; 3) preparing and communicating orally and extemporaneously topics of current animal science interest; and 4) quickly responding to short-answer questions provided in the form of double-elimination quiz bowls. Each team is selected by winning the local AQ at their university. Overall and individual category winning teams are recognized, but team rankings are not emphasized. The ASAS/ADSA members provide leadership for organizing and conducting the AQ, and ASAS and each university provide travel expenses for students. The ultimate purpose is to stimulate academic excellence among undergraduate students and for the students to attend ASAS/ADSA regional scientific meetings to meet faculty and students and to attend scientific research presentations. The purpose of this document was to provide a history of the event and to make recommendations for its improvement. The AQ was conceived in 1967. During the next 10 yr, an ASAS committee developed procedures for a trial AQ held in 1980 at the ASAS Midwestern Section, Kansas State University-Manhattan, and in the next year the first official AQ was held at the ASAS Midwestern Section at the University of Nebraska-Lincoln. Starting in 1985, AQ programs were initiated at the other 3 ASAS sectional meetings, and an estimated 50,000 students representing 60 universities have participated in AQ programs since that time. If the AQ is to continue its improvement over time, it will greatly depend on sustained ASAS/ADSA faculty interest and support, as well as

In 2010 I created Astronomy Night on the National Mall (co-sponsored the White House Office of Science and Technology Policy) with the participation of astronomy clubs, Chandra X-Ray Center, STScI, NASA, NOAO, NSF and the National Air and Space Museum. Since 2009 my NASA-funded Music and Astronomy Under the Stars (MAUS) program has brought astronomy to 50,000 music lovers who attended the Central Park Jazz, Newport Folk, Tanglewood, or Ravinia music festivals or classical, folk, rock, pop, opera, or county-western concerts in local parks assisted by astronomy clubs. MAUS is an evening, nighttime, and cloudy weather traveling astronomy program combining solar, optical, and radio telescope observations; a live image projection system; large outdoor posters and banners; videos; and hands-on activities before and after the concerts or at intermission.

    What is good science? What goal--if any--is the proper end of scientific activity? Is there a legitimating authority that scientists mayclaim? Howserious athreat are the anti-science movements? These questions have long been debated but, as Gerald Holton points out, every era must offer its own responses. This book examines these questions not in the abstract but shows their historic roots and the answers emerging from the scientific and political controversies of this century. Employing the case-study method and the concept of scientific thematathat he has pioneered, Holton displays the broad scope of his insight into the workings of science: from the influence of Ernst Mach on twentiethcentury physicists, biologists, psychologists, and other thinkers to the rhetorical strategies used in the work of Albert Einstein, Niels Bohr, and others; from the bickering between Thomas Jefferson and the U.S. Congress over the proper form of federal sponsorship of scientific research to philosophical debates since Oswald...

    The course Scientific Inquiry at California State University was developed by faculty in biology, physics and English to meet ``writing proficiency'' requirements for non-science majors. Drawing from previous work in composition studies, the position that we take in this course is that we should be engaging students in writing that replicates the work that writing does in science, rather than replicating the particular structural conventions characteristic of scientific writing. That is, scientists use writing to have, remember, share, vet, challenge, and stabilize ideas, and our course requires students use writing to achieve those aims, rather than produce writing that obeys particular conventions of scientific writing. This talk will describe how we have integrated findings from composition studies with a course on scientific inquiry, and provide examples of how scientific communication has resulted from this dialogue.

    Carneiro, Larissa

    2017-11-01

    Full Text Available This article compares forms of visual argumentation in the scientific study of evolution and Young-Earth Creationism, arguing that secular forms of scientific representation have affected the way creationists visually construct their own. In order to affirm their view of the origin of the universe, creationists borrow from, mimic, and ultimately emulate the techniques, or at least the appearance, of scientific method and reasoning. The use of the word “emulation” is very deliberate since their aim is to match and surpass a rival scientific paradigm – evolution. The sermon preached by the design of the Creation Museum in Petersburg, Kentucky, is not content simply to look like science, but aims to do science that is affirmed by the Scriptures.

    Casadevall, Arturo; Fang, Ferric C

    2014-04-01

    As the body of scientific knowledge in a discipline increases, there is pressure for specialization. Fields spawn subfields that then become entities in themselves that promote further specialization. The process by which scientists join specialized groups has remarkable similarities to the guild system of the middle ages. The advantages of specialization of science include efficiency, the establishment of normative standards, and the potential for greater rigor in experimental research. However, specialization also carries risks of monopoly, monotony, and isolation. The current tendency to judge scientific work by the impact factor of the journal in which it is published may have roots in overspecialization, as scientists are less able to critically evaluate work outside their field than before. Scientists in particular define themselves through group identity and adopt practices that conform to the expectations and dynamics of such groups. As part of our continuing analysis of issues confronting contemporary science, we analyze the emergence and consequences of specialization in science, with a particular emphasis on microbiology, a field highly vulnerable to balkanization along microbial phylogenetic boundaries, and suggest that specialization carries significant costs. We propose measures to mitigate the detrimental effects of scientific specialism.

  7. Communicating Science

    Holland, G. J.; McCaffrey, M. S.; Kiehl, J. T.; Schmidt, C.

    2010-12-01

    We are in an era of rapidly changing communication media, which is driving a major evolution in the modes of communicating science. In the past, a mainstay of scientific communication in popular media was through science “translators”; science journalists and presenters. These have now nearly disappeared and are being replaced by widespread dissemination through, e.g., the internet, blogs, YouTube and journalists who often have little scientific background and sharp deadlines. Thus, scientists are required to assume increasing responsibility for translating their scientific findings and calibrating their communications to non-technical audiences, a task for which they are often ill prepared, especially when it comes to controversial societal issues such as tobacco, evolution, and most recently climate change (Oreskes and Conway 2010). Such issues have been politicized and hi-jacked by ideological belief systems to such an extent that constructive dialogue is often impossible. Many scientists are excellent communicators, to their peers. But this requires careful attention to detail and logical explanation, open acknowledgement of uncertainties, and dispassionate delivery. These qualities become liabilities when communicating to a non-scientific audience where entertainment, attention grabbing, 15 second sound bites, and self assuredness reign (e.g. Olson 2009). Here we report on a program initiated by NCAR and UCAR to develop new approaches to science communication and to equip present and future scientists with the requisite skills. If we start from a sound scientific finding with general scientific consensus, such as the warming of the planet by greenhouse gases, then the primary emphasis moves from the “science” to the “art” of communication. The art cannot have free reign, however, as there remains a strong requirement for objectivity, honesty, consistency, and above all a resistance to advocating particular policy positions.

    The Materials Science Program is structured so that NASA s headquarters is responsible for the program content and selection, through the Enterprise Scientist, and MSFC provides for implementation of ground and flight programs with a Discipline Scientist and Discipline Manager. The Discipline Working Group of eminent scientists from outside of NASA acts in an advisory capacity and writes the Discipline Document from which the NRA content is derived. The program is reviewed approximately every three years by groups such as the Committee on Microgravity Research, the National Materials Advisory Board, and the OBPR Maximization and Prioritization (ReMaP) Task Force. The flight program has had as many as twenty-six principal investigators (PIs) in flight or flight definition stage, with the numbers of PIs in the future dependent on the results of the ReMaP Task Force and internal reviews. Each project has a NASA-appointed Project Scientist, considered a half-time job, who assists the PI in understanding and preparing for internal reviews such as the Science Concept Review and Requirements Definition Review. The Project Scientist also insures that the PI gets the maximum science support from MSFC, represents the PI to the MSFC community, and collaborates with the Project Manager to insure the project is well-supported and remains vital. Currently available flight equipment includes the Materials Science Research Rack (MSRR-1) and Microgravity Science Glovebox. Ground based projects fall into one or more of several categories. Intellectual Underpinning of Flight Program projects include theoretical studies backed by modeling and computer simulations; bring to maturity new research, often by young researchers, and may include preliminary short duration low gravity experiments in the KC-135 aircraft or drop tube; enable characterization of data sets from previous flights; and provide thermophysical property determinations to aid PIs.

    2012-12-01

    The NASA Earth Science Technology Office (ESTO) regularly makes investments for nurturing advanced concepts in information technology to enable rapid, low-cost acquisition, processing and visualization of Earth science data in support of future NASA missions and climate change research. In 2012, the National Research Council published a mid-term assessment of the 2007 decadal survey for future spacemissions supporting Earth science and applications [1]. The report stated, "Earth sciences have advanced significantly because of existing observational capabilities and the fruit of past investments, along with advances in data and information systems, computer science, and enabling technologies." The report found that NASA had responded favorably and aggressively to the decadal survey and noted the role of the recent ESTO solicitation for information systems technologies that partnered with the NASA Applied Sciences Program to support the transition into operations. NASA's future missions are key stakeholders for the ESTO technology investments. Also driving these investments is the need for the Agency to properly address questions regarding the prediction, adaptation, and eventual mitigation of climate change. The Earth Science Division has championed interdisciplinary research, recognizing that the Earth must be studied as a complete system in order toaddress key science questions [2]. Information technology investments in the low-mid technology readiness level (TRL) range play a key role in meeting these challenges. ESTO's Advanced Information Systems Technology (AIST) program invests in higher risk / higher reward technologies that solve the most challenging problems of the information processing chain. This includes the space segment, where the information pipeline begins, to the end user, where knowledge is ultimatelyadvanced. The objectives of the program are to reduce the risk, cost, size, and development time of Earth Science space-based and ground

    2010-01-01

    Full Text Available The nanometer regime covers the transition from condensed matter behavior to atomic and molecular properties and thus is a very rich but also very demanding area in materials science. Close to the condensed matter side, properties and functions might still very well be scalable, whereas close to the atomic and molecular side, the scalability is mostly lost. Properties and functions change qualitatively or quantitatively by orders of magnitude when the dimensions become smaller than a critical size in the nanometer range. Examples are the ballistic regime for electron or spin transport at dimensions below the mean free path, near-field effects in scanning near-field optical microscopy and quantum wells when the dimensions are below an appropriate wavelength, novel electronic, mechanical, and chemical properties when the number of bulk atoms becomes smaller than that of surface atoms, quantum conduction, and Coulomb blockade. Thus, by going below a certain size, an abundance of novel properties and functions are at one's disposal, or, in other words, we can functionalize materials simply by reducing their size to the nanoscale.The key to the future lies in the functions that we give to materials, not just in finding 'novel functional materials'. This catch expression in many materials science programs and initiatives of the past two decades sounds great, but it is not what really counts. All materials are functional in one way or another and, therefore, all new materials are 'novel functional materials'. Certainly, finding new materials is always an important part of progress, but we should also focus on the much larger domain of novel functions that we can give to existing or modified materials. A good example is semiconductors: they are fifty or more years old and their properties are very well known, but they were not of widespread interest and use until the transistor changed their destiny into being the central material in the information

  3. Enacting science

    Science.gov (United States)

    MacDonald, Anthony Leo

    My study examines the development of forms of knowing that arise when students engage in open-ended explorations involving self-directed design and building involving simple materials. It is grounded in an enactivist theoretical perspective on cognition which holds that the creation of action-thought processes for engaging the world is interwoven with the meanings that are constructed for these experiences. A dynamic conception of persons-acting-in-a-setting is fundamental to an enactivist view of cognition. How is understanding enacted in building activity? How does the shape of a problem emerge? How do students enact meaning and understanding when they experience a high degree of physical engagement in building things? What are some characteristics of an enactive learning/teaching environment? My research settings comprise a range of individual, group and classroom engagements of varying lengths over a three and one-half year period. The first research episode involved two grade eight students in an investigation of Paper Towels. The second four month engagement was in a grade nine science class that culminated in the building of a Solar House. The third grade ten episode involved a one month project to build a Mousetrap Powered Car. A fourth Invent a Machine project was conducted in two grade eight science classes taught by the teacher who participated in the Solar House project. Two students were present in three of the four projects. I interviewed one of these students upon completion of his high school physics courses. I found that building is a form of thinking which develops competency in managing complex practical tasks. A triadic relationship of exploration, planning and acting is present. Practical and procedural understandings emerge as students enter and re-enter self-directed problem settings. Thinking patterns depend on the kinds of materials chosen, the ways they are used, and on how students contextualize the problem. Classroom assessment

    The nanometer regime covers the transition from condensed matter behavior to atomic and molecular properties and thus is a very rich but also very demanding area in materials science. Close to the condensed matter side, properties and functions might still very well be scalable, whereas close to the atomic and molecular side, the scalability is mostly lost. Properties and functions change qualitatively or quantitatively by orders of magnitude when the dimensions become smaller than a critical size in the nanometer range. Examples are the ballistic regime for electron or spin transport at dimensions below the mean free path, near-field effects in scanning near-field optical microscopy and quantum wells when the dimensions are below an appropriate wavelength, novel electronic, mechanical, and chemical properties when the number of bulk atoms becomes smaller than that of surface atoms, quantum conduction, and Coulomb blockade. Thus, by going below a certain size, an abundance of novel properties and functions are at one's disposal, or, in other words, we can functionalize materials simply by reducing their size to the nanoscale. The key to the future lies in the functions that we give to materials, not just in finding 'novel functional materials'. This catch expression in many materials science programs and initiatives of the past two decades sounds great, but it is not what really counts. All materials are functional in one way or another and, therefore, all new materials are 'novel functional materials'. Certainly, finding new materials is always an important part of progress, but we should also focus on the much larger domain of novel functions that we can give to existing or modified materials. A good example is semiconductors: they are fifty or more years old and their properties are very well known, but they were not of widespread interest and use until the transistor changed their destiny into being the central material in the information technology revolution

    In contemporary research, the supercomputer now ranks, along with radio telescopes, particle accelerators and the other apparatus of "big science", as an expensive resource, which is nevertheless essential for state of the art research. Supercomputers are usually provided as shar.ed central facilities. However, unlike, telescopes and accelerators, they are find a wide range of applications which extends across a broad spectrum of research activity. The difference in performance between a "good" and a "bad" computer program on a traditional serial computer may be a factor of two or three, but on a contemporary supercomputer it can easily be a factor of one hundred or even more! Furthermore, this factor is likely to increase with future generations of machines. In keeping with the large capital and recurrent costs of these machines, it is appropriate to devote effort to training and familiarization so that supercomputers are employed to best effect. This volume records the lectures delivered at a Summer School ...

    Natural scientists from Climate Central and social scientists from Carnegie Mellon University collaborated to develop science communications aimed at presenting personalized coastal flood risk information to the public. We encountered four main challenges: agreeing on goals; balancing complexity and simplicity; relying on data, not intuition; and negotiating external pressures. Each challenge demanded its own approach. We navigated agreement on goals through intensive internal communication early on in the project. We balanced complexity and simplicity through evaluation of communication materials for user understanding and scientific content. Early user test results that overturned some of our intuitions strengthened our commitment to testing communication elements whenever possible. Finally, we did our best to negotiate external pressures through regular internal communication and willingness to compromise.

  8. Selected Aspects of Soil Science History in the USA - Prehistory to the 1970s

    Interest in understanding America's soils originated in prehistory with Native Americans. Following European settlement, notable individuals such as Thomas Jefferson and Lewis and Clark made observations of soil resources. Moving into the 1800s, state geological surveys became involved in soil work and E.W. Hilgard started to formulate ideas similar to those that would eventually lead to V.V. Dokuchaev being recognized as the father of modern soil science. However, Hilgard's advanced ideas on soil genesis were not accepted by the wider American soil science community at the time. Moving into the 1900s, the National Cooperative Soil Survey, the first nationally organized detailed soil survey in the world, was founded under the direction of M. Whitney. Initial soil classification ideas were heavily based in geology, but over time Russian ideas of soil genesis and classification moved into the American soil science community, mainly due to the influence of C.F. Marbut. Early American efforts in scientific study of soil erosion and soil fertility were also initiated in the 1910s and university programs to educate soil scientists started. Soil erosion studies took on high priority in the 1930s as the USA was impacted by the Dust Bowl. Soil Taxonomy, one of the most widely utilized soil classification systems in the world, was developed from the 1950s through the 1970s under the guidance of G.D. Smith and with administrative support from C.E. Kellogg. American soil scientists, such as H. Jenny, R.W. Simonson, D.L. Johnson, and D. Watson-Stegner, developed influential models of soil genesis during the 20th Century, and the use of soil information expanded beyond agriculture to include issues such as land-use planning, soil geomorphology, and interactions between soils and human health.

    PNL research in the marine sciences is focused on establishing a basic understanding of the mechanisms of stress and tolerance in marine organisms exposed to contaminants. Several environmental stressors had been investigated in earlier energy-related research. In a landmark study, for example, PNL had established that the severity of fish disease caused by the common infectious agent, Flexobacter columnaris, was seriously aggravated by thermal enhancement and certain ecological factors. Subsequent studies demonstrated that the primary immune response in fish, challenged by columnaris, could be permanently suppressed by comparatively low tritium exposures. The research has suggested that a potential exists for a significant biological impact when an aquatic stressor is added to an ambient background of other stressors, which may include heat, heavy metal ions, radiation or infectious microorganisms. More recently, PNL investigators have shown that in response to heavy metal contaminants, animals synthesize specific proteins (metallothioneins), which bind and sequester metals in the animals, thus decreasing metal mobility and effects. Companion studies with host-specific intracellular pathogens are being used to investigate the effects of heavy metals on the synthesis of immune proteins, which mitigate disease processes. The results of these studies aid in predicting the ecological effects of energy-related contaminants on valued fin and shellfish species

    Recent work has used large scale molecular dynamics simulations to study the structures and phases of matter in the crusts of neutron stars, with an emphasis on applying techniques in material science to the study of astronomical objects. In the outer crust of an accreting neutron star, a mixture of heavy elements forms following an X-ray burst, which is buried and freezes. We will discuss the phase separation of this mixture, and the composition of the crust that forms. Additionally, calculations of the properties of the crust, such as diffusion coefficients and static structure factors, may be used to interpret observations. Deeper in the neutron star crust, at the base of the inner crust, nuclei are compressed until they touch and form structures which have come to be called 'nuclear pasta.' We study the phases of nuclear pasta with classical molecular dynamics simulations, and discuss how simulations at low density may be relevant to nucleosynthesis in neutron star mergers. Additionally, we discuss the structure factor of nuclear pasta and its impact on the properties of the crust, and use this to interpret observations of crust cooling in low mass X-ray binaries. Lastly, we discuss a correspondence between the structure of nuclear pasta and biophysics.

  11. Bioethics of Universal Knowledge: How Space Science is Transforming Global Culture

    Science.gov (United States)

    Perkins, Kala

    A new universal culture is championing the human race; never before has immersion in the cosmological environment been so clearly presented nor invited as revolutionary a sense of participatory identity to the human race. We are delving into the awareness of a complex relatedness with the expanse of spatial architectures and life that astrophysics and cosmology are revealing. History is marked by waves of interest and inquiry into the possibilities of the existence of other worlds. Since the Renaissance, building of telescopes has been pursued in their quest; now Kepler and other space missions are leading us into direct apprehension of these worlds, scattered across the cosmological landscape. This affords a unique repertoire of dimensionalities in which to re-construe our global cultural evolution and identity. Spatial education, with related social science and humanities, are facilitating the actualization of a universal culture, redefining the collective global heritage, with infinity as our home. The potential significance of space sciences to the human cognitive environment is yet to be fully ascertained. We now understand that the entire history of the universe informs each and every particle and spin of the fabric of existence. The implications of this knowledge have the power to facilitate our overcoming many social diseases such as racism, nationalism and the ideological delusions that tolerate such activities as warfare. Space sciences may help to purge the human cognitive atmosphere of those ills and ignorance that sap global resources, challenging global sustainability, from the economic to the psychosocial. Were the full implications of our united origins and destiny as a cosmic organism to be applied to how we live as a species on the Earth, there would be adequate funds for all manner of science and education such as to transform the global human and ecological landscape in ways as yet only dreamt or fictionalized.

    2013-01-01

    Stewardship science is research important to national security interests that include stockpile stewardship science, homeland security, nuclear forensics, and non-proliferation. To help address challenges in stewardship science and workforce development, the Stewardship Science Academic Alliances (SSAA) was inaugurated ten years ago by the National Nuclear Security Administration of the U. S. Department of Energy. The goal was to enhance connections between NNSA laboratories and the activities of university scientists and their students in research areas important to NNSA, including low-energy nuclear science. This paper presents an overview of recent research in low-energy nuclear science supported by the Stewardship Science Academic Alliances and the applications of this research to stewardship science.

  19. Grassroots Engagement and the University of Washington: Evaluating Science Communication Training Created by Graduate Students for Graduate Students

    Science.gov (United States)

    Rohde, J. A.; Clarkson, M.; Houghton, J.; Chen, W.

    2016-12-01

    Science graduate students increasingly seek science communication training, yet many do not have easy access to training programs. Students often rely on a "do it yourself" approach to gaining communication skills, and student created science communication programs are increasingly found at universities and institutions across the U.S. In 2010, graduate students at the University of Washington led a grassroots effort to improve their own communication and outreach by creating "The Engage Program." With a focus on storytelling and public speaking, this graduate level course not only trains students in science communication but also gives them real world experience practicing that training at a public speaker series at Town Hall Seattle. The Engage Program was fortunate in that it was able to find institutional champions at University of Washington and secure funding to sustain the program over the long-term. However, many grassroots communication programs find it difficult to gain institutional support if there is a perceived lack of alignment with university priorities or lack of return on investment. In order to justify and incentivize institutional support for instruction in science communication, student leaders within the program initiated, designed and carried out an evaluation of their own program focused on assessing the impact of student communication, evaluating the effectiveness of the program in teaching communication skills, and quantifying the benefits of communication training to both the students and their institution. Project leaders created the opportunity for this evaluation by initiating a crowdfunding campaign, which has helped to further engage public support of science communication and incentivized student participation in the program, and may also inspire future program leaders to pursue similar program optimizations.

    Science.gov (United States)

    Summ, Annika; Volpers, Anna-Maria

    2016-10-01

    This article examines the current state of science coverage in German print media. It deals with the following questions: (1) how the main characteristics of science journalism can be described, (2) whether there is a difference between various scientific fields, and (3) how different definitions of science journalism lead to differing findings. Two forms of science coverage were analyzed in a standardized, two-part content analysis of German newspapers (N = 1730 and N = 1640). The results show a significant difference between a narrow and a broad definition of science journalism. In the classic understanding, science journalism is prompted by scientific events and is rather noncritical. Science coverage in a broad sense is defined by a wider range of journalistic styles, driven by non-scientific events, and with a focus on the statements of scientific experts. Furthermore, the study describes the specific role of the humanities and social sciences in German science coverage. © The Author(s) 2015.

  5. Science Olympiad students' nature of science understandings

    Philpot, Cindy J.

    2007-12-01

    Recent reform efforts in science education focus on scientific literacy for all citizens. In order to be scientifically literate, an individual must have informed understandings of nature of science (NOS), scientific inquiry, and science content matter. This study specifically focused on Science Olympiad students' understanding of NOS as one piece of scientific literacy. Research consistently shows that science students do not have informed understandings of NOS (Abd-El-Khalick, 2002; Bell, Blair, Crawford, and Lederman, 2002; Kilcrease and Lucy, 2002; Schwartz, Lederman, and Thompson, 2001). However, McGhee-Brown, Martin, Monsaas and Stombler (2003) found that Science Olympiad students had in-depth understandings of science concepts, principles, processes, and techniques. Science Olympiad teams compete nationally and are found in rural, urban, and suburban schools. In an effort to learn from students who are generally considered high achieving students and who enjoy science, as opposed to the typical science student, the purpose of this study was to investigate Science Olympiad students' understandings of NOS and the experiences that formed their understandings. An interpretive, qualitative, case study method was used to address the research questions. The participants were purposefully and conveniently selected from the Science Olympiad team at a suburban high school. Data collection consisted of the Views of Nature of Science -- High School Questionnaire (VNOS-HS) (Schwartz, Lederman, & Thompson, 2001), semi-structured individual interviews, and a focus group. The main findings of this study were similar to much of the previous research in that the participants had informed understandings of the tentative nature of science and the role of inferences in science, but they did not have informed understandings of the role of human imagination and creativity, the empirical nature of science, or theories and laws.

  9. Neuroscience, neurohistory, and the history of science: a tale of two brain images.

    Science.gov (United States)

    Fuller, Steve

    2014-03-01

    This essay introduces a Focus section on "Neurohistory and History of Science" by distinguishing images of the brain as governor and as transducer: the former treat the brain as the executive control center of the body, the latter as an interface between the organism and reality at large. Most of the consternation expressed in the symposium about the advent of neurohistory derives from the brain-as-governor conception, which is rooted in a "biologistic" understanding of humanity that in recent years has become bound up in various nefarious "neoliberal" political and economic agendas. However, given the sophisticated attitude that neurohistory's leading champion, Daniel Smail, displays toward evolutionary theory's potential impact on historical practice, he is perhaps better understood as part of the brain-as-transducer tradition. This tradition, largely suppressed in current representations of neuroscience, has a strong theological provenance, ultimately concerned with our becoming attuned to the divine frequency, not least by extending the powers of the human nervous system through technology. This essay sympathetically explores the implications of this perspective for historical practice.

    Network Science, Nonlinear Science and Infrastructure Systems has been written by leading scholars in these areas. Its express purpose is to develop common theoretical underpinnings to better solve modern infrastructural problems. It is felt by many who work in these fields that many modern communication problems, ranging from transportation networks to telecommunications, Internet, supply chains, etc., are fundamentally infrastructure problems. Moreover, these infrastructure problems would benefit greatly from a confluence of theoretical and methodological work done with the areas of Network Science, Dynamical Systems and Nonlinear Science. This book is dedicated to the formulation of infrastructural tools that will better solve these types of infrastructural problems. .

    1994-01-01

    This report describes similarities and differences between undergraduate and graduate engineering science students in the context of two general aspects of the educational experience. First, we explore the extent to which students differ regarding the factors that lead to the choice of becoming an engineer or a scientist, current satisfaction with that choice, and career-related goals and objectives. Second, we look at the technical communication practices, habits, and training of engineers and science (Physics) students. The reported data were obtained from a survey of students enrolled in the College of Engineering at the University of Illinois at Urbana-Champaign, Bowling Green State University, and Texas A&M University. The survey was undertaken as part of the NASA/DOD Aerospace Knowledge Diffusion Research Project. Data are reported for the following categories: student demographics; skill importance, skill training, and skill helpfulness; collaborative writing; computer and information technology use and importance, use of electronic networks; use and importance of libraries and library services; use and importance of information sources and products; use of foreign technical reports; and foreign language (reading and speaking) skills.

  15. Informal science education at Science City

    Science.gov (United States)

    French, April Nicole

    The presentation of chemistry within informal learning environments, specifically science museums and science centers is very sparse. This work examines learning in Kansas City's Science City's Astronaut Training Center in order to identify specific behaviors associated with visitors' perception of learning and their attitudes toward space and science to develop an effective chemistry exhibit. Grounded in social-constructivism and the Contextual Model of Learning, this work approaches learning in informal environments as resulting from social interactions constructed over time from interaction between visitors. Visitors to the Astronaut Training Center were surveyed both during their visit and a year after the visit to establish their perceptions of behavior within the exhibit and attitudes toward space and science. Observations of visitor behavior and a survey of the Science City staff were used to corroborate visitor responses. Eighty-six percent of visitors to Science City indicated they had learned from their experiences in the Astronaut Training Center. No correlation was found between this perception of learning and visitor's interactions with exhibit stations. Visitor attitudes were generally positive toward learning in informal settings and space science as it was presented in the exhibit. Visitors also felt positively toward using video game technology as learning tools. This opens opportunities to developing chemistry exhibits using video technology to lessen the waste stream produced by a full scale chemistry exhibit.

    The biomedical sciences have experienced an explosion of data which promises to overwhelm many current practitioners. Without easy access to data science training resources, biomedical researchers may find themselves unable to wrangle their own datasets. In 2014, to address the challenges posed such a data onslaught, the National Institutes of Health (NIH) launched the Big Data to Knowledge (BD2K) initiative. To this end, the BD2K Training Coordinating Center (TCC; bigdatau.org) was funded to facilitate both in-person and online learning, and open up the concepts of data science to the widest possible audience. Here, we describe the activities of the BD2K TCC and its focus on the construction of the Educational Resource Discovery Index (ERuDIte), which identifies, collects, describes, and organizes online data science materials from BD2K awardees, open online courses, and videos from scientific lectures and tutorials. ERuDIte now indexes over 9,500 resources. Given the richness of online training materials and the constant evolution of biomedical data science, computational methods applying information retrieval, natural language processing, and machine learning techniques are required - in effect, using data science to inform training in data science. In so doing, the TCC seeks to democratize novel insights and discoveries brought forth via large-scale data science training.

    A religious perspective on life shapes how and what those with such a perspective learn in science; for some students a religious perspective can hinder learning in science. For such reasons Staver's article is to be welcomed as it proposes a new way of resolving the widely perceived discord between science and religion. Staver notes that Western thinking has traditionally postulated the existence and comprehensibility of a world that is external to and independent of human consciousness. This has led to a conception of truth, truth as correspondence, in which our knowledge corresponds to the facts in this external world. Staver rejects such a conception, preferring the conception of truth as coherence in which the links are between and among independent knowledge claims themselves rather than between a knowledge claim and reality. Staver then proposes constructivism as a vehicle potentially capable of resolving the tension between religion and science. My contention is that the resolution between science and religion that Staver proposes comes at too great a cost—both to science and to religion. Instead I defend a different version of constructivism where humans are seen as capable of generating models of reality that do provide richer and more meaningful understandings of reality, over time and with respect both to science and to religion. I argue that scientific knowledge is a subset of religious knowledge and explore the implications of this for science education in general and when teaching about evolution in particular.

    2014-12-01

    Full Text Available [english] Digital technologies change how scientists access and process information and consequently impact publication forms in science. Even though the core of scientific publications has remained the same, established publication formats, such as the scientific paper or book, are succumbing to the transitions caused by digital technologies. At the same time, new online tools enable new publication forms, such as blogs, microblogs or wikis, to emerge. This article explores the changing and emerging publications forms in science and also reflects upon the changing role of libraries. The transformations of publishing forms are discussed in the context of open science.

  8. Stealth and Natural Disasters: Science, Policy and Human Behavior

    Science.gov (United States)

    Kieffer, S. W.

    2008-12-01

    Geophysicists, earth scientists, and other natural scientists play a key role in studying disasters, and are challenged to convey the science to the public and policy makers (including government and business). I have found it useful to introduce the concept of two general types of disasters to these audiences: natural and stealth. Natural disasters are geological phenomena over which we humans have some, but relatively little, control. Earthquakes, tsunamis, floods and volcanic eruptions are the most familiar examples, but exogenous events such as meteorite impacts, solar flares, and supernovae are also possibly disruptive. Natural disasters typically have an abrupt onset, cause immediate major change, are familiar from the historic record, and get much media and public attention. They cannot be prevented, but preplanning can ameliorate their effects. Natural disasters are increasingly amplified by us (humans), and we are increasingly affected by them due to our expanding presence on the planet. Less familiar disasters are unfolding in the near-term, but they are not happening in the minds of most people. They are approaching us stealthily, and for this reason I propose that we call them stealth disasters. They differ from natural disasters in several important ways: stealth disasters are primarily caused by, or driven by, the interaction of humans with complex cycles of processes on the planet. Examples are: fresh water shortages and contamination, soil degradation and loss, climate changes, ocean degradation. The onset of stealth disasters is incremental rather than abrupt. They may not unfold significantly during the course of one term of political office, but they are unfolding in our lifetime. We as individuals may or may not escape their consequences, but they will affect our children and grandchildren. If humans are familiar with stealth disasters at all, it is from a relatively local experience, e.g., flooding of the Mississippi or the Dust Bowl in the U

  17. Media, risk and science

    CERN Document Server

    Allan, Stuart

    2002-01-01

    How is science represented by the media? Who defines what counts as a risk, threat or hazard, and why? In what ways do media images of science shape public perceptions? What can cultural and media studies tell us about current scientific controversies? "Media, Risk and Science" is an exciting exploration into an array of important issues, providing a much needed framework for understanding key debates on how the media represent science and risk. In a highly effective way, Stuart Allan weaves together insights from multiple strands of research across diverse disciplines. Among the themes he examines are: the role of science in science fiction, such as "Star Trek"; the problem of 'pseudo-science' in "The X-Files"; and how science is displayed in science museums. Science journalism receives particular attention, with the processes by which science is made 'newsworthy' unravelled for careful scrutiny. The book also includes individual chapters devoted to how the media portray environmental risks, HIV-AIDS, food s...

    Since 1957, there has been major reorganization of health care services in Malaysia. This article assesses the changes and challenges in health care delivery in Malaysia and how the management in health care processes has evolved over the years including equitable health care and health care financing. The health care service in Malaysia is changing towards wellness service as opposed to illness service. The Malaysian Ministry of Health (MOH), being the main provider of health services, may need to manage and mobilize better health care services by providing better health care financing mechanisms. It is recommended that partnership between public and private sectors with the extension of traditional medicine complementing western medicine in medical therapy continues in the delivery of health care.

    Full Text Available School social workers (SSWs are known for serving students with social, emotional, and academic needs. Implementing Response to Intervention (RTI/Multi-Tiered System of Supports (MTSS is one avenue in which SSWs play an integral role by guiding the development and implementation of student interventions. RTI/MTSS requires substantive and multifaceted system changes that involve more than simply adopting new approaches. This paradigm shift brings change which may not be desired or easily accepted by school systems. However, developing collaborative relationships and using effective leadership strategies throughout the RTI/MTSS transformation can be a pathway to success. A survey of 192 SSWs in Illinois revealed the challenges that SSWs experienced as the process of implementing RTI/MTSS transformed them into change leaders. This revelation was viewed as an opportunity to closely align social and emotional practices with students’ academic achievement.

    2010-01-01

    During summer 2010, France discovered that she owned a second energy giant, GdF Suez, ranked number two as a power producer just behind EdF, but world number one in the energy domain thanks to the taking over of International Power (UK) in 2010. Until now, GdF Suez and EdF were confronting with each other in a fair game, keeping their respective seizure on their historical monopolies, gas for GdF Suez and electricity for EdF. From now onward the two giants have started an open fight on all markets, with the exception of nuclear energy for which the French government continues to favour EdF. This paper recalls the main steps of the last 15 years of GdF Suez progress, from the Suez investment bank in 1995 to the merger with GdF in 2008 and the acquisition of International Power in 2010. Then it makes a comparative portrait of both GdF Suez and EdF energy groups with their respective advantages and, finally, it ends with an interview of G. Mestrallet, president of GdF Suez who explains the strategy of his group. (J.S.)

    2017-06-01

    As healthcare spending continues to outpace economic growth, legislators and healthcare economists have explored many processes aimed at improving efficiency and reducing waste. Gainsharing or the general concept that organizations and their employees can work together to continually improve outcomes at reduced expenditures in exchange for a portion of the savings has been shown to be effective within the healthcare system. Although gainsharing principles may be applicable to healthcare organizations and their physician partners, specific parameters should be followed when implementing these arrangements. This article will discuss 10 gainsharing strategies aimed at properly aligning healthcare organizations and physicians, which if followed will ensure the successful implementation of gainsharing initiatives.

    Energy Technology Data Exchange (ETDEWEB)

    Fearnley, R. [City of North Vancouver, BC (Canada)

    2003-07-01

    At a Vancouver City council meeting in 1997, a city project engineer presented the concept of a community energy system for Lower Lonsdale. It was recommended that approval be given to proceed with a stage 1 feasibility study and a funding proposal to investigate the initiative. Staff were directed to look for potential partnerships with energy suppliers. Initial partners were BC Gas and BC Hydro. The key actions were to mandate hydronic heating for all new buildings in Lower Lonsdale and to use control over zoning to force developers to install the system infrastructure at their cost. In 1999, a city developer constructed an award winning building with a hydronic heating system. This presentation described the challenges of adapting the concept of a community energy system to the realities of North Vancouver, given its large initial capital expenditure. Traditional district energy in Canada was also reviewed. In 2002, a new community plan was established to promote energy efficient building practices for all development projects and city-owned buildings. The goal was to implement community energy systems for space heating and domestic hot water. The ultimate objective was to minimize greenhouse gas emissions by minimizing the use of non-renewable energy and increasing the use of renewable energy sources. 10 figs.

    In a career that included tenures as president of Stony Brook University, director of Brookhaven National Laboratory, and science advisor to President George W. Bush, John Marburger (1941 2011) found himself on the front line of battles that pulled science ever deeper into the political arena. From nuclear power to global warming and stem cell research, science controversies, he discovered, are never just about science. Science Policy Up Close" presents Marburger s reflections on the challenges science administrators face in the twenty-first century. In each phase of public service Marburger came into contact with a new dimension of science policy. The Shoreham Commission exposed him to the problem of handling a volatile public controversy over nuclear power. The Superconducting Super Collider episode gave him insights into the collision between government requirements and scientists expectations and feelings of entitlement. The Directorship of Brookhaven taught him how to talk to the public about the risks ...

    2012-10-01

    Full Text Available A science experiment is the core tool in science education. This study describes the science teachers' professional competence to implement science experiments in teaching/learning science. The main objective is the motivation of science teachers to use science experiments. The presented research tries to answer questions aimed at the science teachers' skills to use science experiments in teaching/learning science. The research discovered the following facts: science teachers do not include science experiments in teaching/learning in a suitable way; are not able to choose science experiments corresponding to the teaching phase; prefer teachers' demonstration of science experiments; are not able to improvise with the aids; use only a few experiments. The important research result is that an important motivational tool for science teachers is the creation of simple experiments. Examples of motivational simple experiments used into teachers' training for increasing their own creativity and motivation are presented.

    I was a strong proponent of ``science diplomacy'' when I became Science and Technology Adviser to the Secretary of State in 2011. I thought I knew a lot about the subject after being engaged for four decades on international S&T policy issues and having had distinguished scientists as mentors who spent much of their time using science as a tool for building better relations between countries and working to make the world more peaceful, prosperous, and secure. I learned a lot from my three years inside the State Department, including great appreciation and respect for the real diplomats who work to defuse conflicts and avoid wars. But I also learned a lot about science diplomacy, both using science to advance diplomacy and diplomacy to advance science. My talk will focus on the five big things that I learned, and from that the one thing where I am focusing my energies to try to make a difference now that I am a private citizen again.

    As part of a program to increase learning and engagement in science classes 124 Victorian schools are trialing a best practice teaching model. The Science in Schools Research Project is a DEET funded project under the Science in Schools Strategy, developed in response to recent research and policy decisions at national and state levels through which literacy, numeracy and science have been identified as key priorities for learning. This major science research project aims to identify, develop and trial best practice in Science teaching and learning. The Department will then be able to provide clear advice to Victoria's schools that can be adopted and sustained to: * enhance teaching and learning of Science * enhance student learning outcomes in Science at all year levels * increase student access to, and participation in Science learning from Prep through to Year 10, and hence in the VCE as well. The nature of the SiS program will be detailed with specific reference to the innovative programs in solar model cars, robotics and environmental science developed at Forest Hill College in response to this project.

    (Abstract only) New York City in the late 20th century rose to be a planetary capital for the sciences, not just astronomy. This growth was mainly in the academic sector but a parallel growth occurred in the public and home field. With the millennium crossing, scientists in New York agitated for a celebration of the City as a place for a thriving science culture. In 2008 they began World Science Festival. 2011 is the fourth running, on June 1-5, following the AAVSO/AAS meetings. World Science Festival was founded by Dr. Brian Greene, Columbia University, and is operated through the World Science Foundation. The Festival is "saturation science" all over Manhattan in a series of lectures, shows, exhibits, performances. It is staged in "science" venues like colleges and musea, but also in off-science spaces like theaters and galleries. It is a blend from hard science, with lectures like those by us astronomers, to science-themed works of art, dance, music. Events are fitted for the public, either for free or a modest fee. While almost all events are on Manhattan, effort has been made to geographically disperse them, even to the outer boroughs. The grand finale of World Science Festival is a street fair in Washington Square. Science centers in booths, tents, and pavilions highlight their work. In past years this fair drew 100,000 to 150,000 visitors. The entire Festival attracts about a quarter-million attendees. NYSkies is a proud participant at the Washington Square fair. It interprets the "Earth to the Universe" display, debuting during IYA-2009. Attendance at "Earth..." on just the day of the fair plausibly is half of all visitors in America. The presentation shows the scale and scope of World Science Festival, its relation to the City, and how our astronomers work with it.

    Lustig, Harry

    2002-04-01

    Beginning with Bertold Brecht's "Galileo" in 1942 and Friedrich Dürrenmatt's "The Physicists" in 1962, physics and other sciences have served a number of dramatists as backdrops for the exposition of existential problems, as well as the provision of entertainment. Michael Frayn's 1998 play "Copenhagen" broke new ground by giving a central role to the presentation of scientific substance and ideas and to the examination of recent controversial and emotionally charged events in the history of science and of the "real world". A rash of "science plays" erupted. How should we physicists react to this development? Surely, it can be argued, any exposure of science to the public is better than none and will help break down the barriers between the "two cultures". But what if the science or the scientists are badly misrepresented or the play is a weapon to strip science of its legitimacy and its claims to reality and truth? After reviewing a half dozen of the new plays, I conclude that "Copenhagen", though flawed, is not only the best of show, but a positive, even admirable endeavor. The contributions of Bohr, Heisenberg, Born, Schrödinger, and other scientists and their interactions in the golden years of the creation of quantum mechanics are accurately and thrillingly rendered. There may be no better non-technical exposition of complementarity and the uncertainty principle than the one that Frayn puts into the mouths of Bohr and Heisenberg. The treatment of the history of the atomic bomb and Heisenberg's role in Germany's failure to achieve a bomb is another matter. Frayn can also be criticized for applying uncertainly and complementarity to the macroscopic world and, in particular, to human interactions, thereby giving some aid and comfort to the post-modernists. These reservations aside, Copenhagen is a beautiful contribution to the appreciation of science.

Course-based undergraduate research experiences, or CUREs, have been championed for engaging students in research at a scale that is not possible through apprenticeships in faculty research laboratories. Yet there are few if any studies that examine the long-term effects of participating in CUREs on desired student outcomes, such as graduating from college and completing a science, technology, engineering, and mathematics (STEM) major. One CURE program, the Freshman Research Initiative (FRI), has engaged thousands of first-year undergraduates over the past decade. Using propensity score–matching to control for student-level differences, we tested the effect of participating in FRI on students’ probability of graduating with a STEM degree, probability of graduating within 6 yr, and grade point average (GPA) at graduation. Students who completed all three semesters of FRI were significantly more likely than their non-FRI peers to earn a STEM degree and graduate within 6 yr. FRI had no significant effect on students’ GPAs at graduation. The effects were similar for diverse students. These results provide the most robust and best-controlled evidence to date to support calls for early involvement of undergraduates in research. PMID:27252296

    Charles Singer's retrospective diagnosis of Hildegard of Bingen as a migraine sufferer, first made in 1913, has become commonly accepted. This article uses Hildegard as a case study to shift our focus from a polarised debate about the merits or otherwise of retrospective diagnosis, to examine instead what happens when diagnoses take on lives of their own. It argues that simply championing or rejecting retrospective diagnosis is not enough; that we need instead to appreciate how, at the moment of creation, a diagnosis reflects the significance of particular medical signs and theories in historical context and how, when and why such diagnoses can come to do meaningful work when subsequently mobilised as scientific 'fact'. This article first traces the emergence of a new formulation of migraine in the nineteenth century, then shows how this context enabled Singer to retrospectively diagnose Hildegard's migraine and finally examines some of the ways in which this idea has gained popular and academic currency in the second half of the twentieth century. The case of Hildegard's migraine reminds us of the need to historicise scientific evidence just as rigorously as we historicise our other material and it exposes the cumulative methodological problems that can occur when historians use science, and scientists use history on a casual basis.

    The emergence of e-Science over the past decade as a paradigm for Internet-based science was an inevitable evolution of science that built upon the web protocols and access patterns that were prevalent at that time, including Web Services, XML-based information exchange, machine-to-machine communication, service registries, the Grid, and distributed data. We now see a major shift in web behavior patterns to social networks, user-provided content (e.g., tags and annotations), ubiquitous devices, user-centric experiences, and user-led activities. The inevitable accrual of these social networking patterns and protocols by scientists and science projects leads to U-Science as a new paradigm for online scientific research (i.e., ubiquitous, user-led, untethered, You-centered science). U-Science applications include components from semantic e-science (ontologies, taxonomies, folksonomies, tagging, annotations, and classification systems), which is much more than Web 2.0-based science (Wikis, blogs, and online environments like Second Life). Among the best examples of U-Science are Citizen Science projects, including Galaxy Zoo, Stardust@Home, Project Budburst, Volksdata, CoCoRaHS (the Community Collaborative Rain, Hail and Snow network), and projects utilizing Volunteer Geographic Information (VGI). There are also scientist-led projects for scientists that engage a wider community in building knowledge through user-provided content. Among the semantic-based U-Science projects for scientists are those that specifically enable user-based annotation of scientific results in databases. These include the Heliophysics Knowledgebase, BioDAS, WikiProteins, The Entity Describer, and eventually AstroDAS. Such collaborative tagging of scientific data addresses several petascale data challenges for scientists: how to find the most relevant data, how to reuse those data, how to integrate data from multiple sources, how to mine and discover new knowledge in large databases, how to

    , 2007). Some of these newer formats are developed in partnerships between research and education institutions and game developers and are based on learning theory as well as game design methods. Games well suited for creating narrative framework or simulations where students gain first-hand experience......This paper presents a categorisation of science game formats in relation to the educational possibilities or limitations they offer in science education. This includes discussion of new types of science game formats and gamification of science. Teaching with the use of games and simulations...... in science education dates back to the 1970s and early 80s were the potentials of games and simulations was discussed extensively as the new teaching tool ( Ellington et al. , 1981). In the early 90s the first ITC -based games for exploration of science and technical subjects was developed (Egenfeldt...
