    The transition in religious-sponsored health care from a ministry of direct service to one of governance has generated serious and penetrating questions, analyses, and retrenchment. Emphasis on and demand for value-laden leadership development programs are growing at the same time that sponsoring groups are becoming more actively involved in the governance and oversight of their corporate ministries. Two recent Catholic Health Association (CHA) studies focused on the critical governance relationship between the sponsoring group and its incorporated ministries. The first study asked religious institutes and dioceses that were sponsors of CHA member health care freestanding facilities and systems to describe their current governance structure. The second study represented an initial attempt to identify qualitative components of effective governance or sponsorship and asked 19 major superiors and system chief executive officers (CEOs) to characterize an ideal relationship between sponsor and ministry. The studies' findings included the following: In freestanding facilities, lay-religious governing boards have all but replaced the all-sponsor and all-lay advisory boards of the past. Trustee orientation, development, and evaluation were not equally stressed in the three groups surveyed, with trustee evaluation programs lagging behind in all three. Major superiors and CEOs had remarkably similar expectations relating to accountability for mission, relationships between sponsor and corporation, communication, and leadership development. Both major superiors and CEOs looked for greater collaboration in defining roles, translating mission into "business plan", and developing formation programs for leadership. Major superiors' emphasized simplicity of life-style, whereas the CEOs stressed stable commitment to corporate ministry.

    In light of the recent observational data coming from the sky we have two significant directions in the field of theoretical cosmology recently. First, we are now able to make use of present observations, such as the Planck and BICEP2 data, to examine theoretical predictions from the standard inflationary $\\Lambda$CDM which were made decades of years ago. Second, we can search for new cosmological signatures as a way to explore physics beyond the standard cosmic paradigm. In particular, a subset of early universe models admit a nonsingular bouncing solution that attempts to address the issue of the big bang singularity. These models have achieved a series of considerable developments in recent years, in particular in their perturbative frameworks, which made brand-new predictions of cosmological signatures that could be visible in current and forthcoming observations. In this article we present two representative paradigms of very early universe physics. The first is the so-called new matter (or matter-ekpyro...

    The induced polarization (IP) method has been used for the exploration of metallic ore deposits with sulfide minerals such as sphalerite, pyrite, galena, and so on. This method makes use of the capacitive action of the subsurface to locate zones where conductive minerals are disseminated within the host rock. But the IP method has problems with EM coupling and high-power currents that make it difficult to obtain high-quality data in field sites. To address these problems, we have developed an inversion algorithm and field survey techniques using the spectral induced polarization (SIP) method. In this study, we examined the applicability of SIP survey to determine the boundaries of subsurface mineralization and hydrothermal alteration associated with epithermal Au-Ag deposits. A SIP survey was carried out over a wide tuff area, including an area where the silicified zone had been identified from the results of geological and borehole investigations. The survey lines were installed across the silicified zone, and dipole-dipole configurations were used, with electrode spacing of 20m. The transmitter and receiver cables were isolated, and current and potential electrodes were used in stainless steel and non-polarized electrodes, respectively. The data on each survey line were obtained from three frequencies, 0.125 Hz, 1 Hz, and 8Hz. From the survey results, we could image the 2D electrical resistivity and phase difference distributions for each survey line. The boundaries of the silicified zone by hydrothermal alteration were defined by a high resistivity of 500 ohm-m, and the Au-Ag bearing quartz veins by mineralization of the epithermal deposits were defined by a high phase difference of 60 mrad.

    2016-01-01

    Over the last two decades, our understanding of the Milky Way has been improved thanks to large data sets arising from large-area digital sky surveys. The stellar halo is now known to be inhabited by a variety of spatial and kinematic stellar substructures, including stellar streams and stellar clouds, all of which are predicted by hierarchical Lambda Cold Dark Matter models of galaxy formation. In this dissertation, we first present the analysis of spectroscopic observations of individual stars from the two candidate structures discovered using an M-giant catalog from the Two Micron All-Sky Survey. The follow-up observations show that one of the candidates is a genuine structure which might be associated with the Galactic Anticenter Stellar Structure, while the other one is a false detection due to the systematic photometric errors in the survey or dust extinction in low Galactic latitudes. We then presented the discovery of an excess of main sequence turn-off stars in the direction of the constellations of Eridanus and Phoenix from the first-year data of the Dark Energy Survey (DES) – a five-year, 5,000 deg2 optical imaging survey in the Southern Hemisphere. The Eridanus-Phoenix (EriPhe) overdensity is centered around l ~ 285° and b ~ -60° and the Poisson significance of the detection is at least 9σ. The EriPhe overdensity has a cloud-like morphology and the extent is at least ~ 4 kpc by ~ 3 kpc in projection, with a heliocentric distance of about d ~ 16 kpc. The EriPhe overdensity is morphologically similar to the previously-discovered Virgo overdensity and Hercules-Aquila cloud. These three overdensities lie along a polar plane separated by ~ 120° and may share a common origin. In addition to the scientific discoveries, we also present the work to improve the photometric calibration in DES using auxiliary calibration systems, since the photometric errors can cause false detection in first the halo substructure. We present a detailed description of the two

    The Cabinet Office, Government Japan started the Cross-ministerial Strategic Innovation Promotion Program (SIP) in 2014. "Next-generation Ocean Resource Exploration Techniques" is scheduled under SIP from 2014 to 2018. J-MARES participates this program and aims "Multi-stage and integrated approach for Seafloor Massive Sulfide(SMS) exploration" through the development of highly efficient and cost-effective geophysical exploration methods mainly on seismic and EM methods. J-MARES proposed Vertical Cable Seismic (VCS) technique as seismic survey. It is one of reflection seismic methods that uses hydrophone arrays vertically moored from the seafloor. It is useful to delineate detailed structures in a spatially-limited area efficiently. JGI, a member of J-MARES, has developed autonomous VCS systems and carried out several VCS surveys in hydrothermal fields and the detailed subsurface structure is revealed up to 100m. VCS surveys have provides high resolution results but it covers a small survey area with a limited number of vertical cables. To expand the survey area, we operate ROV for re-deployments of the VCS. Another approach is to develop a deep-towed seismic system based on the VCS technology. We re-deployed the vertical cables using ROV. The ROV moved to the location of vertical cable using SSBL navigation and the video information. After arriving the location of vertical cable, the ROV grabbed the anchor and moved it to next target point. We carried out 3 time re-deployment VCS survey with four vertical cables in Iheya North Knoll, Okinawa Trough. The combined seismic sections of the 3 patches are consistent without any gap of each section. Following this, we modified the VCS system to use as a more efficient deep-tow seismic survey system. Although there are other deep-tow seismic systems, signal cables present challenges in deep waters. We use VCS technology in order to avoid these problems. The basic idea is autonomous recording system and we call it ACS

    2014-09-01

    Full Text Available At the time of our investigation, the CU was not a widespread concept in Argentina, being viewed as a “foreign - far long project” (coming from developed countries and standing for the long term. It is suggested that the rate of CU evolution, in emerging countries like Argentina, is more related to mentality issues than to CU strategic or operative limitations. Although the executives who replied to a survey were not the only power factor in their organization, their comments allow us to think that, in those countries, the CU may have a better future perspective. The research used a quali-quantitative methodology, which was based on a survey to top executives of different kinds of companies located in Argentina. The research design was not experimental and transversal, as it was limited to a specific moment in time.

    Geophysical techniques are critical tools of geothermal resource surveys. In recent years, the microtremor survey method, which has two branch techniques (the microtremor sounding technique and the two-dimensional (2D) microtremor profiling technique), has become a common method for geothermal resource exploration. The results of microtremor surveys provide important deep information for probing structures of geothermal storing basins and researching the heat-controlling structures, as well as providing the basis for drilling positions of geothermal wells. In this paper, the southern Jiangsu geothermal resources area is taken as a study example. By comparing the results of microtremor surveys and drilling conclusions, and analyzing microtremor survey effectiveness, and geological and technical factors such as observation radius and sampling frequency, we study the applicability of the microtremor survey method and the optimal way of working with this method to achieve better detection results. A comparative study of survey results and geothermal drilling results shows that the microtremor sounding technique effectively distinguishes sub-layers and determines the depth of geothermal reservoirs in the area with excellent layer conditions. The error of depth is generally no more than 8% compared with the results of drilling. It detects deeper by adjusting the size of the probing radius. The 2D microtremor profiling technique probes exactly the buried structures which display as low velocity anomalies in the apparent velocity profile of the S-wave. The anomaly is the critical symbol of the 2D microtremor profiling technique to distinguish and explain the buried geothermal structures. 2D microtremor profiling results provide an important basis for locating exactly the geothermal well and reducing the risk of drilling dry wells.

    E-health is concerned with promoting the health and wellbeing of individuals, families and communities, and improving professional practice through the use of information management and information and communication technology. In autumn 2010 the RCN, supported by an information technology consultancy, carried out a survey of members' views on e-health to assess their involvement in, and readiness for, e-health developments and their knowledge of its benefits. A total of 1,313 nurses, midwives, healthcare support workers and pre-registration students from across the UK responded. This article describes ways in which nurse managers can influence the successful implementation of the survey recommendations.

    Impending physician shortages in the United States will necessitate greater reliance on physician assistants and nurse practitioners, particularly in primary care. But how willing are Americans to accept that change? This study examines provider preferences from patients' perspective, using data from the Association of American Medical Colleges' Consumer Survey. We found that about half of the respondents preferred to have a physician as their primary care provider. However, when presented with scenarios wherein they could see a physician assistant or a nurse practitioner sooner than a physician, most elected to see one of the other health care professionals instead of waiting. Although our findings provide evidence that US consumers are open to the idea of receiving care from physician assistants and nurse practitioners, it is important to consider barriers to more widespread use, such as scope-of-practice regulations. Policy makers should incorporate such evidence into solutions for the physician shortage.

    2014-01-01

    We describe a methodology to classify periodic variable stars identified in the Wide-field Infrared Survey Explorer (WISE) full-mission single-exposure Source Database. This will assist in the future construction of a WISE periodic-Variable Source Database that assigns variables to specific science classes as constrained by the WISE observing cadence with statistically meaningful classification probabilities. We have analyzed the WISE light curves of 8273 variable stars identified in previous optical variability surveys (MACHO, GCVS, and ASAS) and show that Fourier decomposition techniques can be extended into the mid-IR to assist with their classification. Combined with other periodic light-curve features, this sample is then used to train a machine-learned classifier based on the random forest (RF) method. Consistent with previous classification studies of variable stars in general, the RF machine-learned classifier is superior to other methods in terms of accuracy, robustness against outliers, and relative...

    Exploring Ancient Skies brings together the methods of archaeology and the insights of modern astronomy to explore the science of astronomy as it was practiced in various cultures prior to the invention of the telescope. The book reviews an enormous and growing body of literature on the cultures of the ancient Mediterranean, the Far East, and the New World (particularly Mesoamerica), putting the ancient astronomical materials into their archaeological and cultural contexts. The authors begin with an overview of the field and proceed to essential aspects of naked-eye astronomy, followed by an examination of specific cultures. The book concludes by taking into account the purposes of ancient astronomy: astrology, navigation, calendar regulation, and (not least) the understanding of our place and role in the universe. Skies are recreated to display critical events as they would have appeared to ancient observers - events such as the supernova of 1054, the 'lion horoscope' or the 'Star of Bethlehem.'

    2012-04-01

    Prior research involving response rates in Web-based surveys has not adequately addressed the effect of the reputation of a sponsoring corporation that contracts with a survey provider. This study investigates the effect of two factors, namely, the reputation of a survey's provider and the reputation of a survey's sponsoring corporation, on the willingness of potential respondents to participate in a Web survey. Results of an experimental design with these two factors reveal that the sponsoring corporation's and the survey provider's strong reputations can induce potential respondents to participate in a Web survey. A sponsoring corporation's reputation has a greater effect on the participation willingness of potential respondents of a Web survey than the reputation of the survey provider. A sponsoring corporation with a weak reputation who contracts with a survey provider having a strong reputation results in increased participation willingness from potential respondents if the identity of the sponsoring corporation is disguised in a survey. This study identifies the most effective strategy to increase participation willingness for a Web-based survey by considering both the reputations of the sponsoring corporation and survey provider and whether to reveal their identities.

    We report the discovery and orbital determination of 14 trans-Neptunian objects (TNOs) from the ESSENCE Supernova Survey difference imaging data set. Two additional objects discovered in a similar search of the SDSS-II Supernova Survey database were recovered in this effort. ESSENCE repeatedly observed fields far from the solar system ecliptic (-21{sup o} < {beta} < -5{sup o}), reaching limiting magnitudes per observation of I {approx} 23.1 and R {approx} 23.7. We examine several of the newly detected objects in detail, including 2003 UC{sub 414}, which orbits entirely between Uranus and Neptune and lies very close to a dynamical region that would make it stable for the lifetime of the solar system. 2003 SS{sub 422} and 2007 TA{sub 418} have high eccentricities and large perihelia, making them candidate members of an outer class of TNOs. We also report a new member of the 'extended' or 'detached' scattered disk, 2004 VN{sub 112}, and verify the stability of its orbit using numerical simulations. This object would have been visible to ESSENCE for only {approx}2% of its orbit, suggesting a vast number of similar objects across the sky. We emphasize that off-ecliptic surveys are optimal for uncovering the diversity of such objects, which in turn will constrain the history of gravitational influences that shaped our early solar system.

    You can teach a student a lesson a day but if you teach him to learn by creating curiosity ,he will continue the learning process for life.This abstract is a manifestation of my innate desire as an educator to build students cognitive level of thinking and refine their processes to gain knowledge from the environment ,process it and put it to optimum use. This field survey has been planned and conducted for students of 12th grade (+16yrs). At this level students are introduced to various aspects of Human geography and how human intervention has harnessed environmental resources for its growth and development. They are also encouraged to observe how humans have adapted to the environment and in this process also modified it to satisfy their needs and demands. Students are also sensitized to the understand how geography has evolved as a scientific subject of enquiry. Hence it calls for a deeper understanding and analysis of issues from the local to the global level. Through the pedagogical approach of field survey, they have been oriented to the process of conducting Research -as a well-defined procedure. It involves three phases 1. Planning and preliminary preparation before the survey, 2. During the field survey 3. After the survey compilation, computation and presentation. This activity has been planned over a period of 3 months and as of now the topic and area of case study have been selected. The general concern was studying low rainfall and agriculturally less productive regions hence a case study of a drought prone village- Hiware Bazaar in Ahmednagar district of Maharashtra was undertaken. The site Hiware Bazar has been selected as it is based on the principles of sustainable development and water shed development programme to combat severe drought. The statement of the problem has been defined along with the outlined objectives ,scope of study and the time frame needed to gather the information. The field visit spanned over 5 days for data collection has

  5. Samples and data accessibility in research biobanks: an explorative survey

    2016-02-01

    Full Text Available Biobanks, which contain human biological samples and/or data, provide a crucial contribution to the progress of biomedical research. However, the effective and efficient use of biobank resources depends on their accessibility. In fact, making bio-resources promptly accessible to everybody may increase the benefits for society. Furthermore, optimizing their use and ensuring their quality will promote scientific creativity and, in general, contribute to the progress of bio-medical research. Although this has become a rather common belief, several laboratories are still secretive and continue to withhold samples and data. In this study, we conducted a questionnaire-based survey in order to investigate sample and data accessibility in research biobanks operating all over the world. The survey involved a total of 46 biobanks. Most of them gave permission to access their samples (95.7% and data (85.4%, but free and unconditioned accessibility seemed not to be common practice. The analysis of the guidelines regarding the accessibility to resources of the biobanks that responded to the survey highlights three issues: (i the request for applicants to explain what they would like to do with the resources requested; (ii the role of funding, public or private, in the establishment of fruitful collaborations between biobanks and research labs; (iii the request of co-authorship in order to give access to their data. These results suggest that economic and academic aspects are involved in determining the extent of sample and data sharing stored in biobanks. As a second step of this study, we investigated the reasons behind the high diversity of requirements to access biobank resources. The analysis of informative answers suggested that the different modalities of resource accessibility seem to be largely influenced by both social context and legislation of the countries where the biobanks operate.

    NASA is planning to send humans and robots back to the Moon before 2020. In order for extended missions to be productive, high quality maps of lunar terrain and resources are required. Although orbital images can provide much information, many features (local topography, resources, etc) will have to be characterized directly on the surface. To address this need, we are developing a system to perform site survey and sampling. The system includes multiple robots and humans operating in a variety of team configurations, coordinated via peer-to-peer human-robot interaction. In this paper, we present our system design and describe planned field tests.

    WISE will map the entire sky at 3.3, 4.7, 12 and 23 microns with sensitivities of 0.12, 0.16. 0.65, and 2.6 mJy. WISE will find the most luminous galaxies in the universe, the closest stars to the Sun, and detect most main belt asteroids larger than 3 km. WISE will be placed into a Sun-synchronous polar orbit on a Delta 7320-10 rocket, rotating at a constant rate while a scan mirror freezes the line of sight during each exposure, covering the sky in 6 months following a one month checkout. Orbit to orbit overlap provides 8 or more exposures at each location. The instrument, provided by the Space Dynamics Laboratory, includes an all-reflective aluminum telescope with a 40 cm primary built by SSG-Tinsley, a solid hydrogen cryostat built by Lockheed-Martin's Advanced Technology Center, and 1024x1024 pixel Si:As and HgCdTe arrays built by DRS and Teledyne. Dichroic beamsplitters allow simultaneous images in the four bands over a 47'x47' field of view with 5" resolution to be obtained every 11 seconds. Ball Aerospace is providing the spacecraft, including a 500W fixed solar array, Li-ion battery, two star trackers, reaction wheels, and torque rods. The 50 GB per day of images are losslessly compressed, stored in flash memory, and downlinked at 100 Mbps four times per day using a fixed antenna and TDRSS satellites. The Infrared Processing and Analysis Center will process the data and deliver the image atlas and source catalog, with a preliminary release 6 months after the survey, and a final release 2 years after the survey. JPL manages the project for UCLA PI Ned Wright, and conducts mission operations. Education and Public Outreach is provided by UC Berkeley's Space Science Laboratory. WISE hardware is presently being integrated and tested, with launch scheduled in November 2009.

    Microbiology has a long tradition of making inspirational, world-changing discovery. Microbiology now plays essential roles in many disciplines, leading to some microbiologists raising concern over the apparent loss of identity. An electronic survey was undertaken to capture the scientific identity (based on scientific discipline) of people for whom microbiology forms a part of their profession, in addition to information regarding their first degree (title, country and year in which the degree was completed) and the sector in which they currently work. A total of 447 responses were collected, representing 52 countries from which they gained their first degree. Biology was the most common first degree title (of 32 titles provided), while microbiologist was the most common scientific identity (of 26 identities provided). The data collected in this study gives a snapshot of the multidisciplinarity, specialism and evolving nature of the microbiology academic workforce. While the most common scientific identity chosen in this study was that of a microbiologist, it appears that the microbiological workforce is contributed to by a range of different disciplines, highlighting the cross-cutting, multidisciplined and essential role microbiology has within scientific endeavour. Perhaps, we should be less concerned with labels, and celebrate the success with which our discipline has delivered.

  10. 3D spectroscopic surveys: Exploring galaxy evolution mechanisms

    Epinat, Benoît

    2011-01-01

    I review the major surveys of high redshift galaxies observed using integral field spectroscopy techniques in the visible and in the infrared. The comparison of various samples has to be done with care since they have different properties linked to their parent samples, their selection criteria and the methods used to study them. I present the various kinematic types of galaxies that are identified within these samples (rotators, mergers, etc.) and summarize the discussions on the mass assembly processes at various redshifts deduced from these classifications: at intermediate redshift (z~0.6) merger may be the main mass assembly process whereas the role of cold gas accretion along cosmic web filaments may increase with redshift. The baryonic Tully-Fisher relation is also discussed. This relation seems to be already in place 3 Gyr after the Big-Bang and is then evolving until the present day. This evolution is interpreted as an increase of the stellar mass content of dark matter haloes of a given mass. The dis...

    A sample of RR Lyrae (RRL) variables from the Southern Edgeworth-Kuiper Belt Object survey in regions overlapping the expected position of debris from the interaction of the Sagittarius (Sgr) dwarf galaxy with the Milky Way (RA ~ 20 and 21.5 h; distance 16-21 kpc) has been followed up spectroscopically and photometrically. The 21 photometrically confirmed type ab RRLs have mean [Fe/H] = -1.79 +/- 0.08, consistent with the abundances found for RRLs in a different portion of the Sgr tidal debris stream. The distribution of velocities in the Galactic standard of rest frame (V_GSR) of the 26 RRLs in the region is not consistent with a smooth halo population. Upon comparison with the Sgr disruption models of Law et al (2005), a prominent group of five stars having highly negative radial velocities (V_GSR ~ -175 kms-1) is consistent with predictions for old trailing debris when the Galactic halo is modeled as oblate. The observations also require that the recent trailing debris stream has a broader spread perpendic...

  12. Biomimetics on seed dispersal: survey and insights for space exploration.

    Seeds provide the vital genetic link and dispersal agent between successive generations of plants. Without seed dispersal as a means of reproduction, many plants would quickly die out. Because plants lack any sort of mobility and remain in the same spot for their entire lives, they rely on seed dispersal to transport their offspring throughout the environment. This can be accomplished either collectively or individually; in any case as seeds ultimately abdicate their movement, they are at the mercy of environmental factors. Thus, seed dispersal strategies are characterized by robustness, adaptability, intelligence (both behavioral and morphological), and mass and energy efficiency (including the ability to utilize environmental sources of energy available): all qualities that advanced engineering systems aim at in general, and in particular those that need to enable complex endeavors such as space exploration. Plants evolved and adapted their strategy according to their environment, and taken together, they enclose many desirable characteristics that a space mission needs to have. Understanding in detail how plants control the development of seeds, fabricate structural components for their dispersal, build molecular machineries to keep seeds dormant up to the right moment and monitor the environment to release them at the right time could provide several solutions impacting current space mission design practices. It can lead to miniaturization, higher integration and packing efficiency, energy efficiency and higher autonomy and robustness. Consequently, there would appear to be good reasons for considering biomimetic solutions from plant kingdom when designing space missions, especially to other celestial bodies, where solid and liquid surfaces, atmosphere, etc constitute and are obviously parallel with the terrestrial environment where plants evolved. In this paper, we review the current state of biomimetics on seed dispersal to improve space mission design.

    We quantify the variability of faint unresolved optical sources using a catalog based on multiple SDSS imaging observations. The catalog covers SDSS Stripe 82, which lies along the celestial equator in the Southern Galactic Hemisphere (22h 24m < {alpha}{sub J2000} < 04h 08m, -1.27 < {delta}{sub J2000} < +1.27, {approx}290 deg{sup 2} ), and contains 58 million photometric observations in the SDSS ugriz system for 1.4 million unresolved sources that were observed at least 4 times in each of the gri bands (with a median of 10 observations obtained over {approx}5 years). In each photometric bandpass we compute various low-order lightcurve statistics such as root-mean-square scatter (rms), {chi}{sup 2} 2 per degree of freedom, skewness, minimum and maximum magnitude, and use them to select and study variable sources. We find that 2% of unresolved optical sources brighter than g = 20.5 appear variable at the 0.05 mag level (rms) simultaneously in the g and r bands. The majority (2/3) of these variable sources are low-redshift (< 2) quasars, although they represent only 2% of all sources in the adopted ux-limited sample. We find that at least 90% of quasars are variable at the 0.03 mag level (rms) and confirm that variability is as good a method for finding low-redshift quasars as is the UV excess color selection (at high Galactic latitudes). We analyze the distribution of lightcurve skewness for quasars and find that is centered on zero. We find that about 1/4 of the variable stars are RR Lyrae stars, and that only 0.5% of stars from the main stellar locus are variable at the 0.05 mag level. The distribution of lightcurve skewness in the g-r vs. u-g color-color diagram on the main stellar locus is found to be bimodal (with one mode consistent with Algol-like behavior). Using over six hundred RR Lyrae stars, we demonstrate rich halo substructure out to distances of 100 kpc. We extrapolate these results to expected performance by the Large Synoptic Survey Telescope and

    Full Text Available Composite image of submerged landscapes The North Sea has long been known by archaeologists as an area of Mesolithic occupation, and has even been argued as the heartland of the Mesolithic in North Western Europe. Yet this area remains effectively terra incognita to archaeologists, and the nature of its occupation, tantalisingly elusive. The submergence of this landscape has therefore effectively hindered archaeological research into this vitally important region. Yet this region contains one of the most detailed and comprehensive records of the Late Quaternary and Holocene, and its preserved sedimentary successions represent a mine of information that remains untapped by archaeologists. However the lack of direct data pertaining to this region results in all previous maps of the prehistoric landscape being at best hypothetical. This paper will present results which illustrate that through the utilisation of spatially extensive oil industry data, the recovery information pertaining to the actual Mesolithic landscape of the North Sea is now possible. This information reveals the diversity of this landscape and shows that much greater consideration of submerged Mesolithic landscapes is now required of archaeologists. Whilst the study of such landscapes is in its infancy, the availability of such information offers the possibility of transforming how we interpret traditional terrestrial data and its relationship to the larger European Mesolithic.

  16. Methane Seeps in the Gulf of Mexico: repeat acoustic surveying shows highly temporally and spatially variable venting

    Scientists have recognized that natural seeps account for a large amount of methane emissions. Despite their widespread occurrence in areas like the Gulf of Mexico, little is known about the temporal variability and site-scale spatial variability of venting over time. We used repeat acoustic surveys to compare multiple days of seep activity and determine the changes in the locus of methane emission and plume height. The Sleeping Dragon site was surveyed with an EM302 multibeam sonar on three consecutive days in 2014 and 4 days within one week in 2015. The data revealed three distinctive plume regions. The locus of venting varied by 10-60 meters at each site. The plume that exhibited the least spatial variability in venting, was also the most temporally variable. This seep was present in one-third of survey dates in 2014 and three quarters of survey dates in 2015, showing high day-to-day variability. The plume height was very consistent for this plume, whereas the other plumes were more consistent temporally, but varied in maximum plume height detection by 25-85 m. The single locus of emission at the site that had high day-to-day variability may be due to a single conduit for methane release, which is sometimes closed off by carbonate or clathrate hydrate formation. In addition to day-to-day temporal variability, the locus of emission at one site was observed to shift from a point-source in 2014 to a diffuse source in 2015 at a nearby location. ROV observations showed that one of the seep sites that closed off temporarily, experienced an explosive breakthrough of gas, releasing confined methane and blowing out rock. The mechanism that causes on/off behavior of certain plumes, combined with the spatial variability of the locus of methane release shown in this study may point to carbonate or hydrate formation in the seep plumbing system and should be further investigated.

    We describe a methodology to classify periodic variable stars identified using photometric time-series measurements constructed from the Wide-field Infrared Survey Explorer (WISE) full-mission single-exposure Source Databases. This will assist in the future construction of a WISE Variable Source Database that assigns variables to specific science classes as constrained by the WISE observing cadence with statistically meaningful classification probabilities. We have analyzed the WISE light curves of 8273 variable stars identified in previous optical variability surveys (MACHO, GCVS, and ASAS) and show that Fourier decomposition techniques can be extended into the mid-IR to assist with their classification. Combined with other periodic light-curve features, this sample is then used to train a machine-learned classifier based on the random forest (RF) method. Consistent with previous classification studies of variable stars in general, the RF machine-learned classifier is superior to other methods in terms of accuracy, robustness against outliers, and relative immunity to features that carry little or redundant class information. For the three most common classes identified by WISE: Algols, RR Lyrae, and W Ursae Majoris type variables, we obtain classification efficiencies of 80.7%, 82.7%, and 84.5% respectively using cross-validation analyses, with 95% confidence intervals of approximately ±2%. These accuracies are achieved at purity (or reliability) levels of 88.5%, 96.2%, and 87.8% respectively, similar to that achieved in previous automated classification studies of periodic variable stars.

    Psychologists and economists take contradictory approaches to research on what psychologists call happiness or subjective well-being, and economists call subjective utility. A direct test of the most widely accepted psychological theory, set-point theory, shows it to be flawed. Results are then given, using the economists’ newer “choice approach”—an approach also favored by positive psychologists—which yields substantial payoffs in explaining long-term changes in happiness. Data come from the German Socio-Economic Panel (1984–2008), a unique 25-y prospective longitudinal survey. This dataset enables direct tests of theories explaining long-term happiness. PMID:20921399

    Exploration of the time domain - variable and transient objects and phenomena - is rapidly becoming a vibrant research frontier, touching on essentially every field of astronomy and astrophysics, from the Solar system to cosmology. Time domain astronomy is being enabled by the advent of the new generation of synoptic sky surveys that cover large areas on the sky repeatedly, and generating massive data streams. Their scientific exploration poses many challenges, driven mainly by the need for a real-time discovery, classification, and follow-up of the interesting events. Here we describe the Catalina Real-Time Transient Survey (CRTS), that discovers and publishes transient events at optical wavelengths in real time, thus benefiting the entire community. We describe some of the scientific results to date, and then focus on the challenges of the automated classification and prioritization of transient events. CRTS represents a scientific and a technological testbed and precursor for the larger surveys in the futu...

    Full Text Available Abstract Background Evidence-based public health requires the existence of reliable information systems for priority setting and evaluation of interventions. Existing data systems in the United States are either too crude (e.g., vital statistics, rely on administrative data (e.g., Medicare or, because of their national scope (e.g., NHANES, lack the discriminatory power to assess specific needs and to evaluate community health activities at the state and local level. This manuscript describes the rationale and methods of the Survey of the Health of Wisconsin (SHOW, a novel infrastructure for population health research. Methods/Design The program consists of a series of independent annual surveys gathering health-related data on representative samples of state residents and communities. Two-stage cluster sampling is used to select households and recruit approximately 800-1,000 adult participants (21-74 years old each year. Recruitment and initial interviews are done at the household; additional interviews and physical exams are conducted at permanent or mobile examination centers. Individual survey data include physical, mental, and oral health history, health literacy, demographics, behavioral, lifestyle, occupational, and household characteristics as well as health care access and utilization. The physical exam includes blood pressure, anthropometry, bioimpedance, spirometry, urine collection and blood draws. Serum, plasma, and buffy coats (for DNA extraction are stored in a biorepository for future studies. Every household is geocoded for linkage with existing contextual data including community level measures of the social and physical environment; local neighborhood characteristics are also recorded using an audit tool. Participants are re-contacted bi-annually by phone for health history updates. Discussion SHOW generates data to assess health disparities across state communities as well as trends on prevalence of health outcomes and

    To probe the distribution and physical characteristics of interstellar gas at temperatures T ~ 3e5 K in the disk of the Milky Way, we have used the Far Ultraviolet Spectroscopic Explorer (FUSE) to observe absorption lines of OVI toward 148 early-type stars situated at distances 1 kpc. After subtracting off a mild excess of OVI arising from the Local Bubble, combining our new results with earlier surveys of OVI, and eliminating stars that show conspicuous localized X-ray emission, we find an average OVI mid-plane density n_0 = 1.3e-8 cm^-3. The density decreases away from the plane of the Galaxy in a way that is consistent with an exponential scale height of 3.2 kpc at negative latitudes or 4.6 kpc at positive latitudes. Average volume densities of OVI along different sight lines exhibit a dispersion of about 0.26 dex, irrespective of the distances to the target stars. This indicates that OVI does not arise in randomly situated clouds of a fixed size and density, but instead is distributed in regions that have...

    We present a survey of coronal forbidden lines detected in Far Ultraviolet Spectroscopic Explorer (FUSE) spectra of nearby stars. Two strong coronal features, Fe XVIII 974 A and Fe XIX 1118 A, are observed in 10 of the 26 stars in our sample. Various other coronal forbidden lines, observed in solar flares, also were sought but not detected. The Fe XVIII feature, formed at log T (K) = 6.8, appears to be free of blends, whereas the Fe XIX line can be corrupted by a C I multiplet. FUSE observations of these forbidden iron lines at spectral resolution R ~ 15,000 provides the opportunity to study dynamics of hot coronal plasmas. We find that the velocity centroid of the Fe XVIII feature deviates little from the stellar rest frame, confirming that the hot coronal plasma is confined. The observed line widths generally are consistent with thermal broadening at the high temperatures of formation and show little indication of additional turbulent broadening. The fastest rotating stars, 31 Com, alpha Aur Ab, and AB Dor,...

    We present ground-based spectroscopic verification of six Y dwarfs (see Cushing et al), eighty-nine T dwarfs, eight L dwarfs, and one M dwarf identified by the Wide-field Infrared Survey Explorer (WISE). Eighty of these are cold brown dwarfs with spectral types greater than or equal to T6, six of which have been announced earlier in Mainzer et al and Burgasser et al. We present color-color and color-type diagrams showing the locus of M, L, T, and Y dwarfs in WISE color space. Near-infrared classifications as late as early Y are presented and objects with peculiar spectra are discussed. After deriving an absolute WISE 4.6 um (W2) magnitude vs. spectral type relation, we estimate spectrophotometric distances to our discoveries. We also use available astrometric measurements to provide preliminary trigonometric parallaxes to four our discoveries, which have types of L9 pec (red), T8, T9, and Y0; all of these lie within 10 pc of the Sun. The Y0 dwarf, WISE 1541-2250, is the closest at 2.8 (+1.3,-0.6) pc; if this ...

    Full Text Available Abstract Background Survey data are increasingly abundant from many international projects and national statistics. They are generally comprehensive and cover local, regional as well as national levels census in many domains including health, demography, human development, and economy. These surveys result in several hundred indicators. Geographical analysis of such large amount of data is often a difficult task and searching for patterns is particularly a difficult challenge. Geovisualization research is increasingly dealing with the exploration of patterns and relationships in such large datasets for understanding underlying geographical processes. One of the attempts has been to use Artificial Neural Networks as a technology especially useful in situations where the numbers are vast and the relationships are often unclear or even hidden. Results We investigate ways to integrate computational analysis based on a Self-Organizing Map neural network, with visual representations of derived structures and patterns in a framework for exploratory visualization to support visual data mining and knowledge discovery. The framework suggests ways to explore the general structure of the dataset in its multidimensional space in order to provide clues for further exploration of correlations and relationships. Conclusion In this paper, the proposed framework is used to explore a demographic and health survey data. Several graphical representations (information spaces are used to depict the general structure and clustering of the data and get insight about the relationships among the different variables. Detail exploration of correlations and relationships among the attributes is provided. Results of the analysis are also presented in maps and other graphics.

    Catalina Real-Time Transient Survey (CRTS; http://crts.caltech.edu) is systematically exploring and characterizing the faint, variable sky. It uses data streams generated by the Catalina Sky Survey, which searches for near-Earth asteroids, to search for variable objects and transient events. The CRTS survey has been in operation since 2008, with the archival data going back to 2005. A continuation of the survey has been funded by the NSF, and we are forming an international consortium for an expanded and extended coverage and a broader scientific exploitation. We have a completely open data policy: all discovered transient events are published in real time with no proprietary delay period, and all data are made public, in order to better serve the entire community, and maximize the scientific returns. The survey covers the total area of ~33,000 deg2, down to ~19-21 mag per exposure, with time baselines from 10 min to ~9 years, and growing; there are now typically ~ 300-400 exposures per pointing, and coadded images reach deeper than ~ 23 mag. The area coverage rate will increase substantially as new cameras are being deployed, and possible new data streams opened. The survey has so far detected nearly 10,000 unique, high-amplitude transients, including ~2,500 supernovae (for the last 5 years we published more supernovae than any other survey), >1,200 CVs (the great majority of them previously uncatalogued), >3,000 of blazars and other AGN, and a broad variety of other types of objects. We have ~500 million light curves, which are have been made public and which are being updated continuously. This is an unprecedented data set for the exploration of the time domain, in terms of the area, depth, and temporal coverage. Numerous scientific projects have been enabled by this data stream, including: discoveries of ultraluminous and otherwise peculiar SNe; unusual CVs and dwarf novae; mapping of the structure in the Galactic halo using RR Lyrae; variability

    Despite advances in delirium knowledge and the publication of best practice guidelines, uncertainties exist regarding assessment of Delirium Superimposed on Dementia (DSD). An international survey of delirium specialists was undertaken to evaluate current practice. Invitations to participate in an online survey were distributed by email among members of four international delirium associations with additional publication on their websites. The survey covered the assessment and diagnosis of DSD in clinical practice and research studies. Questions were structured around current practice and attitudes. The 205 responders were mostly confident that they could detect DSD with 60% rating their confidence at 7 or above on a likert scale of 0 (none) to 10 (excellent). Seventy-six percent felt that Dementia with Lewy Bodies (DLB) was the most challenging dementia subtype in which to diagnose DSD. Several scales were used to assess for the presence of DSD including the Confusion Assessment Method (CAM) (54%), DSM-5 criteria (25%) and CAM-ICU (15%). Responders stated that attention (71%), fluctuation in cognitive status (65%), and arousability (41%) were the most clinically useful features to assess when diagnosing DSD. Motor fluctuations were also deemed important but 61% had no specific test to monitor these. The largest survey of DSD practice to date demonstrates that despite good levels of confidence in recognizing DSD, there exists a lack of consensus concerning assessment and diagnosis globally. These findings suggest the need for the development of more research leading to precise diagnostic criteria and comprehensive guidelines regarding the assessment and diagnosis of DSD.

    Correct knowledge about Tuberculosis (TB) is essential for appropriate healthcare seeking behaviour and to accessing diagnosis and treatment services timely. There are several factors influencing knowledge about TB. The present study was conducted to assess the change in community knowledge of Tuberculosis (TB) and its association with respondent's socio-demographic characteristics in two serial knowledge-attitude-practice surveys. Community level interventions including community meetings with youth groups, village health committees and self-help groups and through mass media activities were undertaken to create awareness and knowledge about TB and service availability. Increase in knowledge on TB and its association with respondent's socio-demographic characteristics was assessed by two serial KAP surveys in 2010-2011 (baseline) and 2012-2013 (midline) in 30 districts of India. Correct knowledge of TB was assessed by using lead questions and scores were assigned. The composite score was dichotomized into two groups (score 0-6, poor TB knowledge and score 7-13, good TB knowledge). In baseline and midline survey, 4562 and 4808 individuals were interviewed. The correct knowledge about TB; cough ≥2 weeks, transmission through air, 6-8 months treatment duration, and free treatment increased by 7 % (p-value India and age groups- 25-34 years (OR, 1.3; 95 % CI, 1.1-1.6) and 45-44 years (OR, 1.4; 95 % CI, 1.1-1.7)- were independently associated with good TB knowledge. The knowledge about TB has increased over a period of 2 years and this may be attributable to the community intervention in 30 districts of India. The study offers valuable lesson for designing TB related awareness programmes in India and in other high burden countries.

    This 2015 study investigated whether Lebanese paediatricians diagnosed and managed gastro-oesophageal reflux disease (GERD) in infants and children in accordance with the 2009 guidelines from the North American and European Societies for Paediatric Gastroenterology, Hepatology and Nutrition. Paediatricians members of the Lebanese Order of Physicians with updated email addresses were invited to complete a web-based survey between September and November 2015, to assess their knowledge and management of GERD. Responses were received from 114 of the 543 paediatricians, and 96 were analysed. Only two respondents complied fully with the international guidelines. The majority diagnosed GERD in infants based solely on their medical history and examination. Moreover, nearly two-thirds of the respondents would start an empiric trial with acid suppression. Around half of the respondents considered proton pump inhibitors to be the mainstay of GERD treatment. This was the first Lebanese study that surveyed the management of paediatric GERD. Only 2.1% of the paediatricians followed the guidelines on the evidence-based management of GERD. This highlights the need for studies to assess barriers to guideline implementation and the development of new guidelines accounting for regional factors, mainly the cost of investigations and prevalence of medical insurance. ©2016 Foundation Acta Paediatrica.

    We present ground-based spectroscopic verification of 6 Y dwarfs (see also Cushing et al.), 89 T dwarfs, 8 L dwarfs, and 1 M dwarf identified by the Wide-field Infrared Survey Explorer (WISE). Eighty of these are cold brown dwarfs with spectral types {>=}T6, six of which have been announced earlier by Mainzer et al. and Burgasser et al. We present color-color and color-type diagrams showing the locus of M, L, T, and Y dwarfs in WISE color space. Near-infrared and, in a few cases, optical spectra are presented for these discoveries. Near-infrared classifications as late as early Y are presented and objects with peculiar spectra are discussed. Using these new discoveries, we are also able to extend the optical T dwarf classification scheme from T8 to T9. After deriving an absolute WISE 4.6 {mu}m (W2) magnitude versus spectral type relation, we estimate spectrophotometric distances to our discoveries. We also use available astrometric measurements to provide preliminary trigonometric parallaxes to four of our discoveries, which have types of L9 pec (red), T8, T9, and Y0; all of these lie within 10 pc of the Sun. The Y0 dwarf, WISE 1541-2250, is the closest at 2.8{sup +1.3}{sub -0.6} pc; if this 2.8 pc value persists after continued monitoring, WISE 1541-2250 will become the seventh closest stellar system to the Sun. Another 10 objects, with types between T6 and >Y0, have spectrophotometric distance estimates also placing them within 10 pc. The closest of these, the T6 dwarf WISE 1506+7027, is believed to fall at a distance of {approx}4.9 pc. WISE multi-epoch positions supplemented with positional info primarily from the Spitzer/Infrared Array Camera allow us to calculate proper motions and tangential velocities for roughly one-half of the new discoveries. This work represents the first step by WISE to complete a full-sky, volume-limited census of late-T and Y dwarfs. Using early results from this census, we present preliminary, lower limits to the space density of

    To explore and describe philosophies and characteristics of intensive eating disorder (ED) treatment programs based in tertiary care institutions across Canada. A ninety-item survey examining ED services for adolescents was developed, piloted, and completed by 11 programs across Canada. Information pertaining to program characteristics and components, governance, staffing, referrals, assessments, therapeutic modalities in place, nutritional practices, and treatment protocols were collected. The results highlight the diversity of programming available but also the lack of a unified approach to intensive eating disorder treatment in youth. This report provides important baseline data that offers a framework that programs can use to come together to establish assessment and treatment protocols as well as a process for outcome evaluation. Continued collaboration will be essential moving forward to ensure Canadian youth, regardless of geographic location, receive the necessary treatment required to attain and sustain recovery.

    Mobile phone coverage has grown, particularly within low- and middle-income countries (LMICs), presenting an opportunity to augment routine health surveillance programs. Several LMICs and global health partners are seeking opportunities to launch basic mobile phone-based surveys of noncommunicable diseases (NCDs). The increasing use of such technology in LMICs brings forth a cluster of ethical challenges; however, much of the existing literature regarding the ethics of mobile or digital health focuses on the use of technologies in high-income countries and does not consider directly the specific ethical issues associated with the conduct of mobile phone surveys (MPS) for NCD risk factor surveillance in LMICs. In this paper, we explore conceptually several of the central ethics issues in this domain, which mainly track the three phases of the MPS process: predata collection, during data collection, and postdata collection. These include identifying the nature of the activity; stakeholder engagement; appropriate design; anticipating and managing potential harms and benefits; consent; reaching intended respondents; data ownership, access and use; and ensuring LMIC sustainability. We call for future work to develop an ethics framework and guidance for the use of mobile phones for disease surveillance globally. ©Joseph Ali, Alain B Labrique, Kara Gionfriddo, George Pariyo, Dustin G Gibson, Bridget Pratt, Molly Deutsch-Feldman, Adnan A Hyder.

    To explore barriers that NICU nurses face when attempting to optimally manage newborn pain. Ninety California NICU nurses with current membership in the National Association of Neonatal Nurses (NANN) voluntarily participated. A descriptive survey study. A researcher-developed survey consisting of 37 questions was mailed to 300 NICU nurses; 102 were returned and 90 were usable. Probability sampling from a listing of California registered nurses with current membership in the NANN was used to obtain the study's sampling frame. Less than half of the nurses felt that newborn pain is well managed within the NICUs where they are employed. Barriers identified related to physicians' pain management practices, lack of evidence-based pain management protocols, nurses' and physicians' resistance to change practice, infant pain assessment tools, and inadequate staff training regarding pain assessment and management. A knowledge-practice gap still exists within newborn pain management. Increased caregiver education remains a necessity, but strategies that address resistance to change practice within healthcare settings must also be considered.

    We present an analysis of high proper motion objects that we have found in a recent study and in this work with multi-epoch astrometry from the Wide-field Infrared Survey Explorer (WISE). Using photometry and proper motions from the Two Micron All-Sky Survey and WISE, we have identified the members of this sample that are likely to be late-type, nearby, or metal-poor. We have performed optical and near-infrared spectroscopy on 41 objects, from which we measure spectral types that range from M4-T2.5. This sample includes 11 blue L dwarfs and 5 subdwarfs; the latter were also classified as such in the recent study by Kirkpatrick and coworkers. Based on their spectral types and photometry, several of our spectroscopic targets may have distances of <20 pc with the closest at ∼12 pc. The tangential velocities implied by the spectrophotometric distances and proper motions indicate that four of the five subdwarfs are probably members of the Galactic halo while several other objects, including the early-T dwarf WISE J210529.08–623558.7, may belong to the thick disk.

    We present the results of a mid-infrared survey of II outer Galaxy massive star-forming regions and 3 open clusters with data from the Wide-field Infrared Survey Explorer (WISE). Using a newly developed photometric scheme to identify young stellar objects and exclude extragalactic contamination, we have studied the distribution of young stars within each region. These data tend to support the hypothesis that latter generations may be triggered by the interaction of winds and radiation from the first burst of massive star formation with the molecular cloud material leftover from that earlier generation of stars. We dub this process the "fireworks hypothesis" since star formation by this mechanism would proceed rapidly and resemble a burst of fireworks. We have also analyzed small cutout WISE images of the structures around the edges of these massive star-forming regions. We observe large (1-3 pc size) pillar and trunk-like structures of diffuse emission nebulosity tracing excited polycyclic aromatic hydrocarbon molecules and small dust grains at the perimeter of the massive star-forming regions. These structures contain small clusters of emerging Class I and Class II sources, but some are forming only a single to a few new stars.

    The Wide-Field Infrared Survey Explorer (WISE) has uncovered a striking cluster of young stellar object (YSO) candidates associated with the L1509 dark cloud in Auriga. The WISE observations, at 3.4 μm, 4.6 μm, 12 μm, and 22 μm, show a number of objects with colors consistent with YSOs, and their spectral energy distributions suggest the presence of circumstellar dust emission, including numerous Class I, flat spectrum, and Class II objects. In general, the YSOs in L1509 are much more tightly clustered than YSOs in other dark clouds in the Taurus-Auriga star forming region, with Class I and flat spectrum objects confined to the densest aggregates, and Class II objects more sparsely distributed. We estimate a most probable distance of 485-700 pc, and possibly as far as the previously estimated distance of 2 kpc.

    Full Text Available BACKGROUND: General practitioners (GPs have a key role to play in suicide prevention, but the rates at which they question patients with depression about suicidal thoughts and plans are rather low. Little is known about GPs' characteristics associated with such inquiries. Our objectives were to describe GPs' attitudes, perceived barriers, and self-reported practices in this questioning of these patients and to analyze factors associated with these practices. METHODOLOGY: This cross-sectional survey was conducted among participants in a panel of randomly selected French GPs (1249/1431 participated: 87.3%. GPs were interviewed with a standardized questionnaire covering their professional and personal characteristics, attitudes, and practices in exploring the suicide risk of their patients with depression. We built a suicide inquiry score by summing the responses to 5 items and used a multiple linear regression analysis to explore the characteristics associated with this score. PRINCIPAL FINDINGS: Most GPs reported inquiring about the presence of suicidal ideation often or very often; less than 30% reported that they frequently explored signs of a specific suicide plan. The mean suicide inquiry score was 12.4 (SD, 2.9; range, 5-20. False ideas, such as thinking that patients who report suicidal ideas do not often commit suicide, were frequent (42.3%. Previous continuing medical education on suicide, participation in a formal mental health network, and patients who committed suicide in the past 5 years were associated with a higher score. Reluctance to question patients about suicide and perception of insufficient skill were associated with a lower score. CONCLUSIONS/SIGNIFICANCE: This study showed great variability in French GPs' practices in exploring suicide risk in patients with depression. Interventions aiming at improving GPs' initial training and continuing medical education in suicide and/or depression, and their collaboration with mental

    The Full-sky Astrometric Mapping Explorer (FAME) is a NASA MIDEX mission scheduled for launch in 2004. It will perform an all sky, astrometric survey with unprecedented accuracy. FAME will determine the positions, parallaxes, proper motions, and photometry of 40,000,000 stars with visual band magnitudes 5 DSS colors. FAME will enable a wide range of scientific investigations using its large, rich database of information on stellar properties. It will: * Calibrate the zero point of the extragalactic distance scale to 1% * Determine absolute luminosities of a wide range of spectral types * Detect a meaningful statistical sample of companion stars, brown dwarfs, and giant planets * Enable studies of the kinematics of our galaxy, including the effect of dark matter in the disk * Characterize stellar variability of a large sample of stars at the 0.1% level * Define a rigid optical reference frame for future scientific endeavors FAME is evolved from design concepts from the Hipparcos mission, using current CCD technology to observe more and fainter stars. Like Hipparcos, FAME has a compound mirror consisting of two flats angled relative to each other. The compound mirror feeds the two fields of view separated by the ``basic angle'' into a common telescope. The two fields of view are used to control the growth of stochastic errors in determining the relative separations of stars. FAME is a joint development effort of the U.S. Naval Observatory, the Naval Research Laboratory, Lockheed Martin Missiles and Space Advanced Technology Center, and the Smithsonian Astrophysical Observatory. Funding for FAME is provided by the NASA Office of Space Science through the Explorer program managed by Goddard Space Flight Center. Additional funding has been provided by the U.S. Navy. http://www.usno.navy.mil/fame

    Planet searches using the radial velocity technique show a paucity of companions to solar-type stars within ˜5 au in the mass range of ˜10-80 MJup. This deficit, known as the brown dwarf desert, currently has no conclusive explanation. New substellar companions in this region help assess the reality of the desert and provide insight to the formation and evolution of these objects. Here, we present 10 new brown dwarf and 2 low-mass stellar companion candidates around solar-type stars from the Multi-object APO Radial Velocity Exoplanet Large-Area Survey (MARVELS) of the Sloan Digital Sky Survey III. These companions were selected from processed MARVELS data using the latest University of Florida Two Dimensional pipeline, which shows significant improvement and reduction of systematic errors over previous pipelines. The 10 brown dwarf companions range in mass from ˜13 to 76 MJup and have orbital radii of less than 1 au. The two stellar companions have minimum masses of ˜98 and 100 MJup. The host stars of the MARVELS brown dwarf sample have a mean metallicity of [Fe/H] = 0.03 ± 0.08 dex. Given our stellar sample we estimate the brown dwarf occurrence rate around solar-type stars with periods less than ˜300 d to be ˜0.56 per cent.

    We present a sample of brown dwarfs identified with the Wide-field Infrared Survey Explorer (WISE) for which we have obtained Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) near-infrared grism spectroscopy. The sample (22 in total) was observed with the G141 grism covering 1.10–1.70 μm, while 15 were also observed with the G102 grism, which covers 0.90–1.10 μm. The additional wavelength coverage provided by the G102 grism allows us to (1) search for spectroscopic features predicted to emerge at low effective temperatures (e.g.,ammonia bands) and (2) construct a smooth spectral sequence across the T/Y boundary. We find no evidence of absorption due to ammonia in the G102 spectra. Six of these brown dwarfs are new discoveries, three of which are found to have spectral types of T8 or T9. The remaining three, WISE J082507.35+280548.5 (Y0.5), WISE J120604.38+840110.6 (Y0), and WISE J235402.77+024015.0 (Y1), are the 19th, 20th, and 21st spectroscopically confirmed Y dwarfs to date. We also present HST grism spectroscopy and reevaluate the spectral types of five brown dwarfs for which spectral types have been determined previously using other instruments.

    Near Earth Objects (NEOs) are small Solar System bodies whose orbits bring them close to the Earth's orbit. We are carrying out a Warm Spitzer Cycle 11 Exploration Science program entitled NEOSurvey --- a fast and efficient flux-limited survey of 597 known NEOs in which we derive diameter and albedo for each target. The vast majority of our targets are too faint to be observed by NEOWISE, though a small sample has been or will be observed by both observatories, which allows for a cross-check of our mutual results. Our primary goal is to create a large and uniform catalog of NEO properties. We present here the first results from this new program: fluxes and derived diameters and albedos for 80 NEOs, together with a description of the overall program and approach, including several updates to our thermal model. The largest source of error in our diameter and albedo solutions, which derive from our single band thermal emission measurements, is uncertainty in eta, the beaming parameter used in our thermal modelin...

    In the past, genetic services were delivered to a limited number of families with rare conditions. However, genomics is now being applied to both inherited and common diseases in a range of healthcare settings, and there is a greater need for nurses to understand the basic concepts of genetic health care. The aim of this cross-sectional survey was to explore the understanding and attitudes of Italian nurses toward genetic health care. A questionnaire was completed by 102 nurses and midwives (85% response rate). Of these, 61% believed that genetic counseling was only an informative and advisory process, and 53.9% could not specify to whom the counseling was aimed. When asked to identify nurses' role in genetic health care, 62% of the respondents believed they had no role, although 28% believed that nurses could provide information, support, and counseling. These findings indicate that nurses have only partial knowledge of the issues surrounding genetic health care. To prepare nurses for the post-genomic era, improved genetic education at the undergraduate and postgraduate levels is required.

    We report the discovery of the first new ultra-cool brown dwarf found with the Wide-field Infrared Survey Explorer (WISE). The object's preliminary designation is WISEPC J045853.90+643451.9. Follow-up spectroscopy with the LUCIFER instrument on the Large Binocular Telescope indicates that it is a very late-type T dwarf with a spectral type approximately equal to T9. Fits to an IRTF/SpeX 0.8-2.5 micron spectrum to the model atmospheres of Marley and Saumon indicate an effective temperature of approximately 600 K as well as the presence of vertical mixing in its atmosphere. The new brown dwarf is easily detected by WISE, with a signal-to-noise ratio of ~36 at 4.6 microns. Current estimates place it at a distance of 6 to 10 pc. This object represents the first in what will likely be hundreds of nearby brown dwarfs found by WISE that will be suitable for follow up observations, including those with the James Webb Space Telescope. One of the two primary scientific goals of the WISE mission is to find the coolest, ...

    2011-01-01

    We present the discovery of seven ultracool brown dwarfs identified with the Wide-field Infrared Survey Explorer (WISE). Near-infrared spectroscopy reveals deep absorption bands of H_2O and CH_4 that indicate all seven of the brown dwarfs have spectral types later than UGPS J072227.51-054031.2, the latest type T dwarf currently known. The spectrum of WISEP J182831.08+265037.8 is distinct in that the heights of the J- and H-band peaks are approximately equal in units of f_lambda, so we identify it as the archetypal member of the Y spectral class. The spectra of at least two of the other brown dwarfs exhibit absorption on the blue wing of the H-band peak that we tentatively ascribe to NH_3. These spectral morphological changes provide a clear transition between the T dwarfs and the Y dwarfs. In order to produce a smooth near-infrared spectral sequence across the T/Y dwarf transition, we have reclassified UGPS J0722-0540 as the T9 spectral standard and tentatively assign WISEP J173835.52+273258.9 as the Y0 spect...

    The Galaxy Evolution Explorer (GALEX) imaged the sky in the Ultraviolet (UV) for almost a decade, delivering the first sky surveys at these wavelengths. Its database contains far-UV (FUV, $\\lambda$$_{eff}$ $\\sim$ 1528\\AA) and near-UV (NUV, $\\lambda$$_{eff}$ $\\sim$ 2310\\AA) images of most of the sky, including deep UV-mapping of extended galaxies, over 200 million source measurements, and more than 100,000 low-resolution UV spectra. The GALEX archive will remain a long-lasting resource for statistical studies of hot stellar objects, QSOs, star-forming galaxies, nebulae and the interstellar medium. It provides an unprecedented road-map for planning future UV instrumentation and follow-up observing programs in the UV and at other wavelengths. We review the characteristics of the GALEX data, and describe final catalogs and available tools, that facilitate future exploitation of this database. We also recall highlights from the science results uniquely enabled by GALEX data so far.

    2015-06-01

    The engineering and studies phase of the Glass Buttes project was aimed at reducing risk during the early stages of geothermal project development. The project’s inclusion of high resolution geophysical and geochemical surveys allowed Ormat to evaluate the value of these surveys both independently and in combination to quantify the most valuable course of action for exploration in an area where structure, permeability, and temperature are the most pressing questions. The sizes of the thermal anomalies at Glass Buttes are unusually large. Over the course of Phase I Ormat acquired high resolution LIDAR data to accurately map fault manifestations at the surface and collected detailed gravity and aeromagnetic surveys to map subsurface structural features. In addition, Ormat collected airborne hyperspectral data to assist with mapping the rock petrology and mineral alteration assemblages along Glass Buttes faults and magnetotelluric (MT) survey to try to better constrain the structures at depth. Direct and indirect identification of alteration assemblages reveal not only the geochemical character and temperature of the causative hydrothermal fluids but can also constrain areas of upflow along specific fault segments. All five datasets were merged along with subsurface lithologies and temperatures to predict the most likely locations for high permeability and hot fluids. The Glass Buttes temperature anomalies include 2 areas, totaling 60 km2 (23 mi2) of measured temperature gradients over 165° C/km (10° F/100ft). The Midnight Point temperature anomaly includes the Strat-1 well with 90°C (194 °F) at 603 m (1981 ft) with a 164 °C/km (10°F/100ft) temperature gradient at bottom hole and the GB-18 well with 71°C (160 °F) at 396 m (1300 ft) with a 182°C/km (11°F/100ft) gradient. The primary area of alteration and elevated temperature occurs near major fault intersections associated with Brothers Fault Zone and Basin and Range systems. Evidence for faulting is

    2014-01-01

    We use star, galaxy and quasar spectra taken by the Sloan Sky Digital Survey to map out the distribution of diffuse interstellar bands (DIBs) induced by the Milky Way. We show that, after carefully removing the intrinsic spectral energy distribution of each source, it is possible to measure statistical flux fluctuations at the 1e-3 level, detect about thirty DIBs and measure their strength as a function of position on the sky. We create a map of DIB absorption covering about 5,000 square degrees and measure correlations with various tracers of the interstellar medium: atomic & molecular hydrogen, dust and polycyclic aromatic hydrocarbons (PAHs). After recovering known correlations, we show that each DIB has a different dependence on atomic and molecular hydrogen: while they are all positively correlated with N(HI), they exhibit a range of behaviors with N(H2) showing positive, negative or no correlation. We show that a simple parametrization involving only N(HI) and N(H2) applied to all the DIBs is suffic...

    Chanover, Nancy J.; Holley-Bockelmann, Kelly; Holtzman, Jon A.

    2017-01-01

    In the Summer of 2016 we conducted a 10-week pilot Research Experience for Undergraduates (REU) program aimed at increasing the participation of underrepresented minority undergraduate students in research using data from the Sloan Digital Sky Survey (SDSS). This program utilized a distributed REU model, whereby students worked with SDSS scientists on exciting research projects while serving as members of a geographically distributed research community. The format of this REU is similar to that of the SDSS collaboration itself, and since this collaboration structure has become a model for the next generation of large scale astronomical surveys, the students participating in the SDSS REU received early exposure and familiarity with this approach to collaborative scientific research. The SDSS REU also provided the participants with a low-risk opportunity to audition for graduate schools and to explore opportunities afforded by a career as a research scientist. The six student participants were placed at SDSS REU host sites at the Center for Astrophysics at Harvard University, University of Wisconsin-Madison, Vanderbilt University, and the University of Portsmouth. Their research projects covered a broad range of topics related to stars, galaxies, and quasars, all making use of SDSS data. At the start of the summer the REU students participated in a week-long Boot Camp at NMSU, which served as a program orientation, an introduction to skills relevant to their research projects, and an opportunity for team-building and cohort-forming. To foster a sense of community among our distributed students throughout the summer, we conducted a weekly online meeting for all students in the program via virtual meeting tools. These virtual group meetings served two purposes: as a weekly check-in to find out how their projects were progressing, and to conduct professional development seminars on topics of interest and relevance to the REU participants. We discuss the outcomes of this

    Full Text Available Abstract Background Many individuals diagnosed with Multiple Sclerosis (MS are sensitive to increased body temperature, which has been recognized as correlating with the symptom of fatigue. The need to explore this association has been highlighted. The aim of this study was to investigate the occurrence of heat sensitivity and its relations to disease course, disability, common MS-related symptoms and ongoing immunosuppressive treatments among individuals 65 years of age or younger diagnosed with MS. Methods A cross-sectional designed survey was undertaken. A questionnaire was sent to MS-patients with an Expanded Disability Status Score (EDSS in the interval of 0-6.5 and who were between 20 and 65 years of age, living in an eastern region of Sweden (n = 334. Besides occurrence of heat sensitivity (Yes/No and corresponding questions, the Fatigue Severity Scale (FSS, the MS-related symptom checklist and the Perceived Deficit Questionnaire (PDQ were included. Data were analysed in relation to data level using Chi-square, Mann Whitney U-test, and Student's t-test. Pearson's and Spearman's correlations were calculated. In the logistic regression analyses (enter dichotomized MS-symptoms were used as dependent variables, and EDSS, disease-course, time since onset, heat-sensitivity, age and sex (female/male were independent variables. In the linear regression analyses, enter, mean FSS and summarized PDQ were entered as dependent variables and EDSS, disease-course, time since onset, heat sensitivity, age and sex (female/male were independent variables. Results Of the responding patients (n = 256, 58% reported heat sensitivity. The regression analyses revealed heat sensitivity as a significant factor relating not only to fatigue (p Conclusions Heat sensitivity in MS patients is a key symptom that is highly correlated with disabling symptoms such as fatigue, pain, concentration difficulty and urination urgency.

    We present the discovery of seven ultracool brown dwarfs identified with the Wide-field Infrared Survey Explorer (WISE). Near-infrared spectroscopy reveals deep absorption bands of H{sub 2}O and CH{sub 4} that indicate all seven of the brown dwarfs have spectral types later than UGPS J072227.51-054031.2, the latest-type T dwarf currently known. The spectrum of WISEP J182831.08+265037.8 is distinct in that the heights of the J- and H-band peaks are approximately equal in units of f{sub {lambda}}, so we identify it as the archetypal member of the Y spectral class. The spectra of at least two of the other brown dwarfs exhibit absorption on the blue wing of the H-band peak that we tentatively ascribe to NH{sub 3}. These spectral morphological changes provide a clear transition between the T dwarfs and the Y dwarfs. In order to produce a smooth near-infrared spectral sequence across the T/Y dwarf transition, we have reclassified UGPS 0722-05 as the T9 spectral standard and tentatively assign WISEP J173835.52+273258.9 as the Y0 spectral standard. In total, six of the seven new brown dwarfs are classified as Y dwarfs: four are classified as Y0, one is classified as Y0 (pec?), and WISEP J1828+2650 is classified as >Y0. We have also compared the spectra to the model atmospheres of Marley and Saumon and infer that the brown dwarfs have effective temperatures ranging from 300 K to 500 K, making them the coldest spectroscopically confirmed brown dwarfs known to date.

  18. Seismic refraction surveys for coal exploration in the Homehills, Hawkdun and Roxburgh areas of Central Otago

    1982-09-01

    Seismic refraction surveys were made during 1979 and 1980 in the Homehills, Hawkdun, and Roxburgh basins formed in the Mesozoic and Paleozoic rocks of Central Otago. They were made to help define the extent of Tertiary coal deposits by determining thicknesses of Cenozoic rocks. The extent of the surveys in the three basins were 12.1, 8.8, and 8.2 line kilometres distributed over 9, 6 and 7 lines respectively. The seismic observations and sonic logs from drill holes were used to derive vertical sections showing distributions of compressional wave velocity with depth. Velocities detected in the Homehills and Hawkdun basins of below 0.5 k/s were usually associated with soil layers, those from 1.0 to 1.5 km/s with Quaternary sediments which are not water saturated, from 1.6 to 1.9 km/s with Tertiary lacustrine or littoral sediments, those from 2.1 to 2.6 km/s with late Tertiary or Quarternary gravels, and those exceedings 3.2 km/s with Mesozoic basement rocks. No overall one-to-one relationship between velocities detected in the range 2.6 to 3.2 km/s and rock types was evident. Velocities encountered at Roxburgh included those between 0.5 and 1.5 km/s which were associated with non-saturated Cenozoic sediments, those between 1.5 and 2.3 km/s representing saturated Cenozoic sediments, those over 3.0 km/s representing Paleozoic schist, and those between 2.3 and 3.0 km/s for which a clear relationship with rock type was not established. Survey results indicate that most of the western boundary of the Homehills basin is unlikely to be associated with a major fault, but the north-east boundary of the basin is associated with a reverse fault having a throw of between 160 and 170 metres. A fault of throw exceeding 300 m has been detected separating the Cenozoic filled Homehills basin, with its base at about 500 m above sea level, from the much deeper Ida Valley basin. The maximum thickness of Cenozoic sediments in the Homehills basin is about 250 m. (16 refs.)

    Piazza, Federico; Marinoni, Christian

    2013-01-01

    We use the effective field theory of dark energy to explore the space of modified gravitymodels which are capable of driving the present cosmic acceleration. We identify five universal functions of cosmic time, which are enough to describe a wide range of theories containing a single scalar degree of freedom in addition to the metric. The first function (the effective equation of state) uniquely controls the expansion history of the universe. The remaining four functions appear in the linear cosmological perturbation equations, but only three of them regulate the growth history of large scale structures. We propose a specific parameterization of such functions in terms of characteristic coefficients that serve as coordinates in the space of modified gravity theories and can be effectively constrained by the next generation of cosmological experiments. We address in full generality the problem of the soundness of the theory against ghost-like and gradient instabilities and show how the space of non-pathologica...

    A mobile mass spectrometer to measure He concentrations has been developed by the U.S. Geological Survey. This instrument has been tested in areas of known uranium deposits, and He anomalies have been found in both soil gas and water. A gas sample is collected in a hypodermic syringe, injected into the spectrometer, and analyzed for He. Over 100 analyses a day can be performed with a sensitivity of 10 parts per billion (ppb). One detailed study conducted in Weld County, Colorado, shows that values for He in soil gas can be contoured to outline an anomalous area and that the anomaly is displaced from the deposit in the direction of groundwater flow. Other studies include the Schwartzwalder uranium mine, Jefferson County, Colorado, where He anomalies may be related to geologic structure; near Ambrosia Lake, New Mexico, where the location of He anomalies are related to groundwater movement; and tests for diurnal effects showing only slight variations probably related to soil-moisture content. ?? 1979.

  1. Draped aeromagnetic survey in Transantarctic Mountains over the area of the Butcher Ridge igneous complex showing extent of underlying mafic intrusion

    2002-01-01

    A draped aeromagnetic survey over the area surrounding the Butcher Ridge igneous complex (BRIC), Transantarctic Mountains, was acquired in 1997-1998 as part of a larger Transantarctic Mountains Aerogeophysical Research Activity survey. The BRIC is a sill-like hypoabyssal intrusion ranging in composition from tholeiitic basalt to rhyolite. An 40Ar/39 Ar age of 174 Ma and the chemical character of the basaltic rocks show the BRIC to be part of the widespread Jurassic Ferrar suite of continental tholeiitic rocks, that extends for 3500 km across Antarctica. The aeromagnetic survey shows a horseshoe-shaped pattern of anomalies reaching amplitudes as great as 1900 nT generally associated with the bedrock topography where it is exposed. It is apparent that the high-amplitude anomaly pattern is more extensive than the 10-km-long exposed outcrop, first crossed by a single 1990 aeromagnetic profile. The highest-amplitude anomalies appear south of the profile acquired in 1990 and extend out of the survey area. The new aeromagnetic data allow determination of the extent of the interpreted Butcher mafic(?) intrusion beneath exposures of Beacon sedimentary rock and ice in the area covered, as well as beneath the small BRIC exposure. The magnetic anomalies show a minimum area of 3000 km2, a much greater extent than previously inferred. Magnetic models indicate a minimum thickness of ???1-2 km for a horizontal intrusion. However, nonunique models with magnetic layers decreasing in apparent susceptibility with depth are consistent with of a 4- to 8-km-thick layered intrusion. These magnetic models indicate progressively deeper erosion of the interpreted mafic-layered body from the south to north. The erosion has removed more magnetic upper layers that mask the magnetic effects of the lower less magnetic layers. The probable minimum volume of the intrusion in the area of the survey is ???6000 km3. An alternate, but less likely, interpretation of a series of dikes can also fit the

    A sound decision regarding combination of datasets is critical for research validity. Data were collected between 1996 and 2000 via a 99-item survey of substance use behaviors. Two groups of 7th-12th grade students in predominately White communities are compared: 166,578 students from 193 communities with high survey participation and 41,259 students from 65 communities with lower participation. Hierarchical logistic models are used to explore whether the two datasets may be combined for further study of community-level substance use effects. "Scenario analysis" is introduced. Results suggest the datasets may reasonably be combined. Limitations and further research are discussed.

  5. Polybrominated diphenyl ethers in U.S. Meat and poultry from two statistically designed surveys showing trends and levels from 2002 to 2008.

    2011-05-25

    Polybrominated diphenyl ether (PBDE) body burdens in the general U.S. population have been linked to the consumption of red meat and poultry. Exposure estimates have also indicated that meat products are a major contributor to PBDE dietary intake. To establish solid estimates of PBDE concentrations in domestic meat and poultry, samples from two statistically designed surveys of U.S. meat and poultry were analyzed for PBDEs. The two surveys were conducted in 2002-2003 and 2007-2008, between which times the manufacturing of penta-BDE and octa-BDE formulations had ceased in the United States (December 2004). Thus, the data provided an opportunity to observe prevalence and concentration trends that may have occurred during this time frame and to compare the mean PBDE levels among the meat and poultry industries. On the basis of composite samples, the average sum of the seven most prevalent PBDEs (BDE-28, -47, -99, -100, -153, -154, and -183) decreased by >60% from 1.95 ng/g lipid in 2002-2003 to 0.72 ng/g lipid in 2007-2008 for meat and poultry. PBDEs measured in individual samples in 2008 showed that beef samples had the lowest PBDE levels followed by hogs and chickens and then by turkeys. The PBDE congener pattern was the same for both surveys and resembled the penta-BDE formulation with BDE-47 and -99 accounting for 30 and 40% of the total, respectively. On the basis of the data from the two surveys, it appears that PBDE levels in U.S. meat and poultry have declined since manufacturing ceased; however, exposure pathways of PBDEs to livestock are still not known.

    2015-01-01

    Full Text Available This study explores the attitudinal and motivational factors underlying graduate students’ attitudes towards team research. Guided by the Theory of Planned Behavior, we hypothesize that attitude, subjective norm, and perceived behavioral control are three major determinants of graduate students’ intentions to conduct team research. An instrument was developed to measure the influences of these factors on students’ intentions and relevant scholarly productivity. A total of 281 graduate students from a large, comprehensive university in the southwest United States participated in the survey. Descriptive statistics reveal that around two-thirds of graduate students have no co-authored manuscripts submitted for publication since they started graduate school. Factor analyses validated the factor structure of the instrument, and the results of Structural Equation Modeling show that (a graduate students’ attitudes towards team research have a positive correlation with their attitudes towards individual research; (b attitude towards team research, subjective norm, and perceived behavioral control, along with students’ discipline/major areas and classification, account for 58% of the variance in the intention to conduct team research; and (c subjective norm appears to be the most influential factor in the model, followed by attitude; while perceived behavioral control is not of much importance. These findings provide implications for academic departments and programs to promote graduate students’ team research. Specifically, creating a climate for collaborative research in academic programs/disciplines/universities may work jointly with enhancing students’ appraisals of such collaborations.

    We present the discovery of five late-type T dwarfs identified with the Wide-field Infrared Survey Explorer (WISE). Low-resolution near-infrared spectroscopy obtained with the Magellan Folded-port InfraRed Echellette (FIRE) reveal strong water and methane absorption in all five sources, and spectral indices and comparison to spectral templates indicate classifications ranging from T5.5 to T8.5:. The spectrum of the latest-type source, WISE J1812+2721, is an excellent match to that of the T8.5 companion brown dwarf Wolf 940B. WISE-based spectrophotometric distance estimates place these T dwarfs at 12-13 pc from the Sun, assuming they are single. Preliminary fits of the spectral data to the atmosphere models of Saumon & Marley indicate effective temperatures ranging from 600 K to 930 K, both cloudy and cloud-free atmospheres, and a broad range of ages and masses. In particular, two sources show evidence of both low surface gravity and cloudy atmospheres, tentatively supporting a trend noted in other young b...

    Background Research showed that promising approaches such as benchmarking, operations research, lean management and six sigma, could be adopted to improve patient logistics in healthcare. To our knowledge, little research has been conducted to obtain an overview on the use, combination and effects of approaches to improve patient logistics in hospitals. We therefore examined the approaches and tools used to improve patient logistics in Dutch hospitals, the reported effects of these approaches on performance, the applied support structure and the methods used to evaluate the effects. Methods A survey among experts on patient logistics in 94 Dutch hospitals. The survey data were analysed using cross tables. Results Forty-eight percent of all hospitals participated. Ninety-eight percent reported to have used multiple approaches, 39% of them used five or more approaches. Care pathways were the preferred approach by 43% of the hospitals, followed by business process re-engineering and lean six sigma (both 13%). Flowcharts were the most commonly used tool, they were used on a regular basis by 94% of the hospitals. Less than 10% of the hospitals used data envelopment analysis and critical path analysis on a regular basis. Most hospitals (68%) relied on external support for process analyses and education on patient logistics, only 24% had permanent internal training programs on patient logistics. Approximately 50% of the hospitals that evaluated the effects of approaches on efficiency, throughput times and financial results, reported that they had accomplished their goals. Goal accomplishment in general hospitals ranged from 63% to 67%, in academic teaching hospitals from 0% to 50%, and in teaching hospitals from 25% to 44%.

    This report has been prepared by the US Department of Energy (DOE) as part of a Research Development Demonstration Testing and Evaluation (RDDT E) project by EG G Energy Measurement's (EG G/EM) Remote Sensing Laboratory. It examines geophysical detection techniques which may be used in Environmental Restoration/Waste Management (ER/WM) surveys to locate buried waste, waste containers, potential waste migratory paths, and aquifer depths. Because of the Remote Sensing Laboratory's unique survey capabilities, only those technologies which have been adapted or are capable of being adapted to an airborne platform were studied. This survey describes several of the available subsurface survey technologies and discusses the basic capabilities of each: the target detectability, required geologic conditions, and associated survey methods. Because the airborne capabilities of these survey techniques have not been fully developed, the chapters deal mostly with the ground-based capabilities of each of the technologies, with reference made to the airborne capabilities where applicable. The information about each survey technique came from various contractors whose companies employ these specific technologies. EG G/EM cannot guarantee or verify the accuracy of the contractor information; however, the data given is an indication of the technologies that are available.

    Guanine-rich sequences have the propensity to fold into a four-stranded DNA structure known as a G-quadruplex (G4). G4 forming sequences are abundant in the promoter region of several oncogenes and become a key target for anticancer drug binding. Here we have studied the interactions of two structurally similar dietary plant flavonoids fisetin and naringenin with G4 as well as double stranded (duplex) DNA by using different spectroscopic and modeling techniques. Our study demonstrates the differential binding ability of the two flavonoids with G4 and duplex DNA. Fisetin more strongly interacts with parallel G4 structure than duplex DNA, whereas naringenin shows stronger binding affinity to duplex rather than G4 DNA. Molecular docking results also corroborate our spectroscopic results, and it was found that both of the ligands are stacked externally in the G4 DNA structure. C-ring planarity of the flavonoid structure appears to be a crucial factor for preferential G4 DNA recognition of flavonoids. The goal of this study is to explore the critical effects of small differences in the structure of closely similar chemical classes of such small molecules (flavonoids) which lead to the contrasting binding properties with the two different forms of DNA. The resulting insights may be expected to facilitate the designing of the highly selective G4 DNA binders based on flavonoid scaffolds.

    We investigate the light-element behavior of red giant stars in Northern globular clusters (GCs) observed by the SDSS-III Apache Point Observatory Galactic Evolution Experiment (APOGEE). We derive abundances of nine elements (Fe, C, N, O, Mg, Al, Si, Ca, and Ti) for 428 red giant stars in 10 globular clusters. The intrinsic abundance range relative to measurement errors is examined, and the well-known C-N and Mg-Al anticorrelations are explored using an extreme-deconvolution code for the first time in a consistent way. We find that Mg and Al drive the population membership in most clusters, except in M107 and M71, the two most metal-rich clusters in our study, where the grouping is most sensitive to N. We also find a diversity in the abundance distributions, with some clusters exhibiting clear abundance bimodalities (for example M3 and M53) while others show extended distributions. The spread of Al abundances increases significantly as cluster average metallicity decreases as previously found by other works, ...

  16. An integrated geophysical survey of Kilbourne Hole, southern New Mexico: Implications for near surface exploration of Mars and the Moon

    Science.gov (United States)

    Maksim, Nisa

    Features such as the Home Plate plateau on Mars, a suspected remnant of an ancient phreatomagmatic eruption, can reveal important information about paleohydrologic conditions. The eruption intensity of a phreatomagmatic volcano is controlled mainly by the quantity of water and magma, the internal geometry of the volcano, and the depth of the interaction zone between magma and water. In order to understand the paleohydrologic conditions at the time of eruption, we must understand all the factors that influenced the phreatomagmatic event. I conducted an integrated geophysical survey, which are magnetic and gravity surveys, and a ground-penetrating radar (GPR) surveys at Kilbourne Hole, a phreatomagmatic crater in southern New Mexico. These investigations serve an analog paleo-hydrogeological study that could be conducted on Mars and the Moon with an implication for planetary exploration. These geophysical surveys are designed to delineate the internal structure of a phreatomagmatic volcano and to define the volumes and masses of volcanic dikes and excavation unit, the depth of feeder dikes, and impacted velocity of the volcanic blocks. For the gravity and magnetic surveys at Kilbourne Hole, I collected data at a total of 171 gravity survey stations and 166 magnetics survey stations. A 2D gravity and magnetic inverse model was developed jointly to map the body of the magma intrusions and the internal structure of Kilbourne Hole. A total of 6 GPR surveys lines were also completed at Kilbourne Hole to image and to define locations of pyroclastic deposits, volcanic sags and blocks, the sizes distribution of volcanic blocks, and the impact velocity of the volcanic blocks. Using the size distribution and impact velocity of volcanic blocks from our GPR data, I derived the initial gas expansion velocity and the time duration of the gas expansion phase of the Kilbourne Hole eruption. These obtained parameters (volumes, masses, and depths of the feeder dikes and the excavation

    High throughput sequencing technologies are revolutionizing genetic research. With this "rise of the machines", genomic sequences can be obtained even for unknown genomes within a short time and for reasonable costs. This has enabled evolutionary biologists studying genetically unexplored species to identify molecular markers or genomic regions of interest (e.g. micro- and minisatellites, mitochondrial and nuclear genes) by sequencing only a fraction of the genome. However, when using such datasets from non-model species, it is possible that DNA from non-target contaminant species such as bacteria, viruses, fungi, or other eukaryotic organisms may complicate the interpretation of the results. In this study we analysed 14 genomic pyrosequencing libraries of aquatic non-model taxa from four major evolutionary lineages. We quantified the amount of suitable micro- and minisatellites, mitochondrial genomes, known nuclear genes and transposable elements and searched for contamination from various sources using bioinformatic approaches. Our results show that in all sequence libraries with estimated coverage of about 0.02-25%, many appropriate micro- and minisatellites, mitochondrial gene sequences and nuclear genes from different KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways could be identified and characterized. These can serve as markers for phylogenetic and population genetic analyses. A central finding of our study is that several genomic libraries suffered from different biases owing to non-target DNA or mobile elements. In particular, viruses, bacteria or eukaryote endosymbionts contributed significantly (up to 10%) to some of the libraries analysed. If not identified as such, genetic markers developed from high-throughput sequencing data for non-model organisms may bias evolutionary studies or fail completely in experimental tests.

    Full Text Available The “gender gap” on various physics conceptual evaluations has been extensively studied. Men’s average pretest scores on the Force Concept Inventory and Force and Motion Conceptual Evaluation are 13% higher than women’s, and post-test scores are on average 12% higher than women’s. This study analyzed the gender differences within the Conceptual Survey of Electricity and Magnetism (CSEM in which the gender gap has been less well studied and is less consistent. In the current study, data collected from 1407 students (77% men, 23% women in a calculus-based physics course over ten semesters showed that male students outperformed female students on the CSEM pretest (5% and post-test (6%. Separate analyses were conducted for qualitative and quantitative problems on lab quizzes and course exams and showed that male students outperformed female students by 3% on qualitative quiz and exam problems. Male and female students performed equally on the quantitative course exam problems. The gender gaps within CSEM post-test scores, qualitative lab quiz scores, and qualitative exam scores were insignificant for students with a CSEM pretest score of 25% or less but grew as pretest scores increased. Structural equation modeling demonstrated that a latent variable, called Conceptual Physics Performance/Non-Quantitative (CPP/NonQnt, orthogonal to quantitative test performance was useful in explaining the differences observed in qualitative performance; this variable was most strongly related to CSEM post-test scores. The CPP/NonQnt of male students was 0.44 standard deviations higher than female students. The CSEM pretest measured CPP/NonQnt much less accurately for women (R^{2}=4% than for men (R^{2}=17%. The failure to detect a gender gap for students scoring 25% or less on the pretest suggests that the CSEM instrument itself is not gender biased. The failure to find a performance difference in quantitative test performance while detecting a gap in

    2017-04-01

    Albeit limited, some emerging work, using convenience-based samples, has demonstrated that greater motor skill development is associated with higher physical activity among preschool-aged children. The purpose of this study was to evaluate this topic using data from the 2012 National Youth Fitness Survey that included 329 preschool-aged children (3-5 years). Parents proxy-reported their child's physical activity, with motor skill level assessed from the Test of Gross Motor Development-Second Edition (TGMD2). Motor skill levels (Gross Motor Quotient, locomotor or object control) were not associated with preschool free-living physical activity in any analytic model. Thus, in this large sample of preschoolers, contrary to research with older children, motor skill level was not associated with physical activity. Findings are discussed in terms of study limitations of (a) a reliance on parent report of children's physical activity levels and (b) the possibility that physical activity data within the national survey were too limited in range to show possible associations to motor skill development with higher levels of free-living physical activity in preschoolers.

    We describe photometric recalibration of data obtained by the asteroid survey LINEAR. Although LINEAR was designed for astrometric discovery of moving objects, the data set described here contains over 5 billion photometric measurements for about 25 million objects, mostly stars. We use Sloan Digital Sky Survey (SDSS) data from the overlapping {approx}10,000 deg{sup 2} of sky to recalibrate LINEAR photometry and achieve errors of 0.03 mag for sources not limited by photon statistics with errors of 0.2 mag at r {approx} 18. With its 200 observations per object on average, LINEAR data provide time domain information for the brightest four magnitudes of the SDSS survey. At the same time, LINEAR extends the deepest similar wide-area variability survey, the Northern Sky Variability Survey, by 3 mag. We briefly discuss the properties of about 7000 visually confirmed periodic variables, dominated by roughly equal fractions of RR Lyrae stars and eclipsing binary stars, and analyze their distribution in optical and infrared color-color diagrams. The LINEAR data set is publicly available from the SkyDOT Web site.

  6. 18,000 displacement vectors and 44 positions surveys of RFID tracers show a normal diffusion of the bedload in a proglacial stream (Bossons glacier, France)

    2016-04-01

    Bedload transport is a stochastic process during which each particle hops for a random length then rests for a random duration. In recent years, this probabilistic approach was investigated by theoretical models, numerical simulations and laboratory experiments. These experiments are generally carried out on short time scales with sand, but underline the diffusive behaviour of the bedload. Conversely, marked pebbles in natural streams have mainly be used to infer about transport processes and transport time of the bedload. In this study, the stochastic characteristics of bedload transport are inferred from the radio-frequency identification (RFID) of pebbles. In particular, we provide insights for answering the following question : is the bedload transport sub-diffusive, normally diffusive or super-diffusive at the long time scale (i.e. global range)? Experiments designed to investigate the phenomenology of bedload transport have been carried out in the proglacial area of Bossons glacier. This 350 m long alluvial plain exhibits daily flood from the glacial system and is still redistributing material from catastrophic events pre-dating our investigations. From 2011 to 2014, the position of the ˜ 1000 RFID tracers have been measured by a mobile antenna and a differential GPS during 44 surveys providing ˜ 2500 tracer positions. Additionnaly, in 2014, 650 new tracers were seeded upstream from a static RFID antenna located at the outlet of the study area. For the 1 to 32 cm fraction surveyed, both mobile and static antenna results show no evidence for a significant export outside of the surveyed zone. Initial data have been maximized by using each possible campaign pairs leading to ˜700 campaign pairs and more than 18,000 displacement vectors. To our knowledge, this is one of the most extensive dataset of tracers positions measured in a natural stream using the RFID methodology. Using 152 campaigns pairs with at least 20 retrieved tracers,r standard probability

    For the purpose of reducing the risk of deep geothermal resource development, the paper investigated three factors for the formation of geothermal resource in the deep underground, that is, heat supply from heat source, supply of geothermal fluids, and the developmental status of fracture systems forming reservoir structures. The survey further clarified the status of existence of deep geothermal resource and the whole image of the geothermal system including shallow geothermal energy in order to research/study usability of deep geothermal resource. In the deep geothermal resource survey, drilling/examination were made of a deep geothermal exploration well (`WD-1,` target depth: approximately 3,000-4,000m) in the already developed area, with the aim of making rationalized promotion of the geothermal development. And the status of existence of deep geothermal resource and the whole image of the geothermal system were clarified to investigate/study usability of the geothermal system. In fiscal 1995, `WD-1` in the Kakkonda area reached a depth of 3,729m. By this, surveys were made to grasp the whole image of the shallow-deep geothermal system and to obtain basic data for researching usability of deep geothermal resource. 22 refs., 531 figs., 136 tabs.

    We investigate the light-element behavior of red giant stars in northern globular clusters (GCs) observed by the SDSS-III Apache Point Observatory Galactic Evolution Experiment. We derive abundances of 9 elements (Fe, C, N, O, Mg, Al, Si, Ca, and Ti) for 428 red giant stars in 10 GCs. The intrinsic abundance range relative to measurement errors is examined, and the well-known C–N and Mg–Al anticorrelations are explored using an extreme-deconvolution code for the first time in a consistent way. We find that Mg and Al drive the population membership in most clusters, except in M107 and M71, the two most metal-rich clusters in our study, where the grouping is most sensitive to N. We also find a diversity in the abundance distributions, with some clusters exhibiting clear abundance bimodalities (for example M3 and M53) while others show extended distributions. The spread of Al abundances increases significantly as cluster average metallicity decreases as previously found by other works, which we take as evidence that low metallicity, intermediate mass AGB polluters were more common in the more metal-poor clusters. The statistically significant correlation of [Al/Fe] with [Si/Fe] in M15 suggests that {sup 28}Si leakage has occurred in this cluster. We also present C, N, and O abundances for stars cooler than 4500 K and examine the behavior of A(C+N+O) in each cluster as a function of temperature and [Al/Fe]. The scatter of A(C+N+O) is close to its estimated uncertainty in all clusters and independent of stellar temperature. A(C+N+O) exhibits small correlations and anticorrelations with [Al/Fe] in M3 and M13, but we cannot be certain about these relations given the size of our abundance uncertainties. Star-to-star variations of α-element (Si, Ca, Ti) abundances are comparable to our estimated errors in all clusters.

    The West African Taoudeni basin covers a desert area of about 1.8 million km² and is one of the last frontier basins worldwide. Here Wintershall Holding AG holds acreage of about 68000 km². During 2005-2007 geological surveys and an aero-gravity and -magnetic survey were conducted in this area. The potential field modelling should contribute first insight about the subsurface to plan an economic seismic survey. 2D models lead to poor results. 2008 the results of an internship (NK) were 3D subsurface models, which were enhanced during the following diploma thesis (Köther, 2009). Complex igneous rocks and sparsely distributed constraints lead to an ambiguous interpretation. Therefore, several simple 3D models were compiled with the in-house software IGMAS+, which base on geological ideas of the underground and fit well the measured data. These basic models allow a geophysical evaluation of different geological theories about the subsurface. Also, for a thorough interpretation field transformations (Euler, Curvature, and Derivatives) were calculated. These results led to new constraints for further interpretation of the basin structures and therefore they are important contributions for future exploration e.g. the planning of seismic surveys.

  17. Recent surveys in the forests of Ulu Segama Malua, Sabah, Malaysia, show that orang-utans (P. p. morio can be maintained in slightly logged forests.

    Full Text Available BACKGROUND: Today the majority of wild great ape populations are found outside of the network of protected areas in both Africa and Asia, therefore determining if these populations are able to survive in forests that are exploited for timber or other extractive uses and how this is managed, is paramount for their conservation. METHODOLOGY/PRINCIPAL FINDINGS: In 2007, the "Kinabatangan Orang-utan Conservation Project" (KOCP conducted aerial and ground surveys of orang-utan (Pongo pygmaeus morio nests in the commercial forest reserves of Ulu Segama Malua (USM in eastern Sabah, Malaysian Borneo. Compared with previous estimates obtained in 2002, our recent data clearly shows that orang-utan populations can be maintained in forests that have been lightly and sustainably logged. However, forests that are heavily logged or subjected to fast, successive coupes that follow conventional extraction methods, exhibit a decline in orang-utan numbers which will eventually result in localized extinction (the rapid extraction of more than 100 m(3 ha(-1 of timber led to the crash of one of the surveyed sub-populations. Nest distribution in the forests of USM indicates that orang-utans leave areas undergoing active disturbance and take momentarily refuge in surrounding forests that are free of human activity, even if these forests are located above 500 m asl. Displaced individuals will then recolonize the old-logged areas after a period of time, depending on availability of food sources in the regenerating areas. CONCLUSION/SIGNIFICANCE: These results indicate that diligent planning prior to timber extraction and the implementation of reduced-impact logging practices can potentially be compatible with great ape conservation.

    Precise airborne temperature surveys depicted small predawn surface temperature differences related to heat flow anomalies at the Long Valley, California, KGRA. Zones with conductive heat flow differences of 45 + or - 16 nu cal/sq cm(s) has predawn surface temperature differences of 1.4 + or - 0.3 C. The warmer zones had hot water circulating in a shallow (less than 60-m-deep) aquifer. Hot wate is a useful geochemical indicator of geothermal and mineral resource potential. The precise airborne temperature survey method recorded redundant infrared scanner signals at two wavelengths (10 to 12 micrometers and 4.5 to 5.5 micrometers) and two elevations (0.3 km and 1.2 km). Ground thermistor probes recorded air and soil temperatures during the survey overflights. Radiometric temperatures were corrected for air path and reflected sky radiation effects. Corrected temperatures were displayed in image form with color coded maps which depicted 0.24 C temperature differences.

    Context. As observational evidence steadily accumulates, the nature of the Galactic bulge has proven to be rather complex: the structural, kinematic, and chemical analyses often lead to contradictory conclusions. The nature of the metal-rich bulge - and especially of the metal-poor bulge - and their relation with other Galactic components, still need to be firmly defined on the basis of statistically significant high-quality data samples. Aims: We used the fourth internal data release of the Gaia-ESO survey to characterize the bulge metallicity distribution function (MDF), magnesium abundance, spatial distribution, and correlation of these properties with kinematics. Moreover, the homogeneous sampling of the different Galactic populations provided by the Gaia-ESO survey allowed us to perform a comparison between the bulge, thin disk, and thick disk sequences in the [Mg/Fe] vs. [Fe/H] plane in order to constrain the extent of their eventual chemical similarities. Methods: We obtained spectroscopic data for 2500 red clump stars in 11 bulge fields, sampling the area -10° ≤ l ≤ + 8° and -10° ≤ b ≤ -4° from the fourth internal data release of the Gaia-ESO survey. A sample of 6300 disk stars was also selected for comparison. Spectrophotometric distances computed via isochrone fitting allowed us to define a sample of stars likely located in the bulge region. Results: From a Gaussian mixture models (GMM) analysis, the bulge MDF is confirmed to be bimodal across the whole sampled area. The relative ratio between the two modes of the MDF changes as a function of b, with metal-poor stars dominating at high latitudes. The metal-rich stars exhibit bar-like kinematics and display a bimodality in their magnitude distribution, a feature which is tightly associated with the X-shape bulge. They overlap with the metal-rich end of the thin disk sequence in the [Mg/Fe] vs. [Fe/H] plane. On the other hand, metal-poor bulge stars have a more isotropic hot kinematics and do

    Full Text Available Abstract Title An exploration of socioeconomic variation in lifestyle factors and adiposity in the Ontario Food Survey through structural equation models. Background Socioeconomic indicators have been inversely associated with overweight and obesity, with stronger associations observed among women. The objective of the present secondary analysis was to examine the relationships among socioeconomic measures and adiposity for men and women participating in the Ontario Food Survey (OFS, and to explore lifestyle factors as potential mediators of these associations. Methods The cross-sectional 1997/98 OFS collected anthropometric measurements, a food frequency questionnaire, data on socio-demographics (age, sex, income, and education and physical activity from 620 women and 467 men, ages 18 to 75. Based on the 2003 Health Canada guidelines, waist circumference and BMI values were used to derive least risk, increased risk, and high risk adiposity groups. Structural equation modeling was conducted to examine increased risk and high risk adiposity in relation to education and income, with leisure time physical activity, fruit and vegetable intake, and smoking status included as potential mediators of these associations. Results The probability of high risk adiposity was directly associated with education (β-0.19, p Conclusion The socioeconomic context of adiposity continues to differ greatly between men and women. For women only in the OFS, fruit and vegetable intake contributed to the inverse association between education and high risk adiposity; however, additional explanatory factors are yet to be determined.

    During the "WISE at 5: Legacy and Prospects" conference in Pasadena, CA -- which ran from February 10 - 12, 2015 -- attendees were invited to engage in an interactive session exploring the future uses of the Wide-field Infrared Survey Explorer (WISE) data. The 65 participants -- many of whom are extensive users of the data -- brainstormed the top questions still to be answered by the mission, as well as the complementary current and future datasets and additional processing of WISE/NEOWISE data that would aid in addressing these most important scientific questions. The results were mainly bifurcated between topics related to extragalactic studies (e.g. AGN, QSOs) and substellar mass objects. In summary, participants found that complementing WISE/NEOWISE data with cross-correlated multiwavelength surveys (e.g. SDSS, Pan-STARRS, LSST, Gaia, Euclid, etc.) would be highly beneficial for all future mission goals. Moreover, developing or implementing machine-learning tools to comb through and understand cross-corre...

    2004-12-01

    We present here ``The XMM-Newton Bright Serendipitous Survey'', composed of two flux-limited samples: the XMM-Newton Bright Source Sample (BSS, hereafter) and the XMM-Newton ``Hard'' Bright Source Sample (HBSS, hereafter) having a flux limit of f_x≃ 7 × 10-14 erg cm-2 s-1 in the 0.5-4.5 keV and 4.5-7.5 keV energy band, respectively. After discussing the main goals of this project and the survey strategy, we present the basic data on a complete sample of 400 X-ray sources (389 of them belong to the BSS, 67 to the HBSS with 56 X-ray sources in common) derived from the analysis of 237 suitable XMM-Newton fields (211 for the HBSS). At the flux limit of the survey we cover a survey area of 28.10 (25.17 for the HBSS) sq. deg. The extragalactic number-flux relationships (in the 0.5-4.5 keV and in the 4.5-7.5 keV energy bands) are in good agreement with previous and new results making us confident about the correctness of data selection and analysis. Up to now ˜ 71% (˜ 90%) of the sources have been spectroscopically identified making the BSS (HBSS) the sample with the highest number of identified XMM-Newton sources published so far. At the X-ray flux limits of the sources studied here we found that: a) the optical counterpart in the majority (˜ 90%) of cases has a magnitude brighter than the POSS II limit (R ˜ 21mag); b) the majority of the objects identified so far are broad line AGN both in the BSS and in the HBSS. No obvious trend of the source spectra (as deduced from the Hardness Ratios analysis) as a function of the count rate is measured and the average spectra of the ``extragalactic'' population corresponds to a (0.5-4.5 keV) energy spectral index of ˜ 0.8 (˜ 0.64) for the BSS (HBSS) sample. Based on the hardness ratios we infer that about 13% (40%) of the sources in the BSS (HBSS) sample are described by an energy spectral index flatter than that of the cosmic X-ray background. Based on previous X-ray spectral results on a small subsample of objects we

  8. The detection and exploration of planets from the Trans-atlantic Exoplanet Survey

    Science.gov (United States)

    O'Donovan, Francis Thomas

    I present the discovery of three transiting planets (TrES-2, TrES-3, and TrES-4) of nearby bright stars made with the ten-centimeter telescope Sleuth as part of the Trans-atlantic Exoplanet Survey (TrES). TrES-2 is the first transiting exoplanet detected in the field of view of NASA’s Kepler mission. Of the 20 known transiting exoplanets, TrES-3 has the second shortest period, facilitating the study of orbital decay and atmospheric evaporation. Its visible/infrared brightness makes TrES-3 an ideal target for observations to determine the atmospheric composition. TrES-4 has the largest radius and lowest density of the known transiting planets. These three planets have radii larger than that of Jupiter, and the radius of TrES-4 significantly exceeds predictions from models of hot Jupiters, indicating a possible lack of an energy source in these models. I present the results of Spitzer observations of TrES-2. I reject tidal dissipation of eccentricity as an explanation for the inflated radius, and examine the spectrum for evidence of atmospheric absorption.I have monitored 19 fields each containing 6,000-36,000 stars for evidence of transits. I discuss the rejection of six of my candidate transiting systems from an early field that represent examples of the 67 astrophysical false positives that I encountered in Sleuth data. These six false positives highlight the benefit of a multisite survey such as TrES, and also of comprehensive follow-up of transit candidates. As a further example, I present the candidate GSC 03885-00829 from Sleuth data that was revealed to be a blend of a bright F dwarf and a fainter K-dwarf eclipsing binary. This candidate proved nontrivial to reject, requiring multicolor follow-up photometry to produce evidence of the true binary nature of this candidate.The yield of planets from transit surveys is not yet well constrained or understood. There are numerous factors that affect the predictions such as the amount of correlated photometric noise

    We present the results of a search for Sloan Digital Sky Survey (SDSS) emission-line galaxies with very red 3.4mum - 4.6mum (W1-W2) colours in the Wide-field Infrared Survey Explorer (WISE) Preliminary Release Source Catalogue (PRSC) aiming to find objects with hot dust emission. For this purpose we considered a sample of ~16000 galaxies with strong emission lines selected out of a total of ~900000 SDSS spectra and identified them with the PRSC sources. We find that ~5000 sources out of the ~16000 SDSS galaxies are present in the PRSC, including ~1000 galaxies with sufficiently strong [OIII]4363 emission lines to permit reliable determinations of the oxygen abundance. No correlation of W1-W2 with metallicity is found. On the other hand, there is clear evidence for a redder W1-W2 index in galaxies with higher Hbeta luminosity and higher Hbeta equivalent width, implying that strong UV radiation from young starbursts efficiently heats interstellar dust to high temperatures. However, galaxies with very red colour...

    We present 11 candidate late-type companions to nearby stars identified with data from the Wide-field Infrared Survey Explorer (WISE) and the Two Micron All-Sky Survey (2MASS). Eight of the candidates are likely to be companions based on their common proper motions with the primaries. The remaining three objects are rejected as companions, one of which is a free-floating T7 dwarf. Spectral types are available for five of the companions, which consist of M2V, M8.5V, L5, T8, and T8. Based on their photometry, the unclassified companions are probably two mid-M dwarfs and one late-M/early-L dwarf. One of the T8 companions, WISE J142320.84+011638.0, has already been reported by Pinfield and coworkers. The other T8 companion, ULAS J095047.28+011734.3, was discovered by Burningham and coworkers through the United Kingdom Infrared Telescope Infrared Deep Sky Survey, but its companionship has not been previously recognized in the literature.

Among the possible mechanisms that have been previously proposed for the peculiar colors of these L dwarfs, low metallicity does not appear to be a viable explanation for 2MASS J17430860+8526594 since our spectrum of the primary suggests that its metallicity is not significantly subsolar.

    VENGA is a large-scale extragalactic IFU survey, which maps the bulges, bars and large parts of the outer disks of 32 nearby normal spiral galaxies. The targets are chosen to span a wide range in Hubble types, star formation activities, morphologies, and inclinations, at the same time of having vast available multi-wavelength coverage from the far-UV to the mid-IR, and available CO and 21cm mapping. The VENGA dataset will provide 2D maps of the SFR, stellar and gas kinematics, chemical abundances, ISM density and ionization states, dust extinction and stellar populations for these 32 galaxies. The uniqueness of the VIRUS-P large field of view permits these large-scale mappings to be performed. VENGA will allow us to correlate all these important quantities throughout the different environments present in galactic disks, allowing the conduction of a large number of studies in star formation, structure assembly, galactic feedback and ISM in galaxies.

    The study summarizes the current data, generates some new data, and recommends further steps which should be taken to investigate the electrical power production potential of Newberry volcano. The objective was to concentrate on data from the developable flanks of the volcano. All previous data on the geology, hydrology, and geophysics were summarized. A soil-mercury survey focused on the flanks of the volcano was conducted. Samples from 1000 km/sup 2/ of the volcano were analyzed for mercury content. All this information was utilized to evaluate (1) the likelihood of future discovery of electrical-quality geothermal fluids on the flanks, and (2) the most cost-effective means of improving the quality of available power generation estimates for the volcano. 37 figures.

    Qualitative research findings are increasingly used to inform decision-making. Research has indicated that not all quantitative research on the effects of interventions is disseminated or published. The extent to which qualitative researchers also systematically underreport or fail to publish certain types of research findings, and the impact this may have, has received little attention. A survey was delivered online to gather data regarding non-dissemination and dissemination bias in qualitative research. We invited relevant stakeholders through our professional networks, authors of qualitative research identified through a systematic literature search, and further via snowball sampling. 1032 people took part in the survey of whom 859 participants identified as researchers, 133 as editors and 682 as peer reviewers. 68.1% of the researchers said that they had conducted at least one qualitative study that they had not published in a peer-reviewed journal. The main reasons for non-dissemination were that a publication was still intended (35.7%), resource constraints (35.4%), and that the authors gave up after the paper was rejected by one or more journals (32.5%). A majority of the editors and peer reviewers "(strongly) agreed" that the main reasons for rejecting a manuscript of a qualitative study were inadequate study quality (59.5%; 68.5%) and inadequate reporting quality (59.1%; 57.5%). Of 800 respondents, 83.1% "(strongly) agreed" that non-dissemination and possible resulting dissemination bias might undermine the willingness of funders to support qualitative research. 72.6% and 71.2%, respectively, "(strongly) agreed" that non-dissemination might lead to inappropriate health policy and health care. The proportion of non-dissemination in qualitative research is substantial. Researchers, editors and peer reviewers play an important role in this.

    laboratory facilities, MIS and COSmIC, that have been developed for this study and discuss the findings resulting from the comparison of the laboratory data with high resolution, high S/N ratio astronomical observations. MIS stands for Matrix Isolation Spectroscopy, a well-proven technique for isolating cold molecular species in inert solid environments. COSmIC stands for Cosmic Simulation Chamber. It combines a supersonic free jet expansion with discharge plasma and high-sensitivity cavity ringdown spectroscopy and time-of-flight mass spectrometry detection tools for the generation and the detection of cold, isolated gas-phase molecules and ions under experimental conditions that closely mimic interstellar conditions. The column densities of the individual neutral PAH molecules and ions probed in these surveys are derived from the comparison of these unique laboratory data with high resolution, high S/N ratio astronomical observations. The comparisons of astronomical and laboratory data lead to clear and unambiguous conclusions regarding the expected abundances for PAHs of various sizes and charge states in the interstellar environments probed in the surveys. Band profile comparisons between laboratory and astronomical spectra lead to information regarding the molecular structures and characteristics associated with the DIB carriers in the corresponding lines-of-sight. These quantitative surveys of neutral and ionized PAHs in the optical range open the way for unambiguous quantitative searches of PAHs and complex organics in a variety of interstellar and circumstellar environments.

    Quasars at high redshift are an important and unique probe of the distant Universe, for understanding the origin and progress of cosmic reionization, the early growth of supermassive black holes, and the evolution of quasar host galaxies and their dark matter halos, among other topics. We are currently carrying out a new spectroscopic survey, called SHELLQs (Subaru High-z Exploration of Low-Luminosity Quasars), to search for low-luminosity quasars at z > 6. By exploiting the exquisite imaging data produced by the Subaru Hyper Suprime-Cam (HSC) survey, we aim to probe quasar luminosities down to M1450 ~ -22 mag, i.e., below the classical threshold between quasars and Seyfert galaxies. Candidate selection is performed by combining several photometric approaches including a Bayesian probabilistic algorithm. A large spectroscopic observing program is underway, using Subaru/FOCAS, GTC/OSIRIS, and Gemini/GMOS; in particular, SHELLQs has been approved as a Subaru intensive program to use 20 nights in the coming four semesters. As of August 2016, we have discovered ~40 quasars and bright galaxies at z ~ 6 and beyond, from the first 100 deg2 of the HSC survey (Matsuoka et al. 2016, ApJ, 828, 26). Surprisingly, we are starting to see the steep rise of the luminosity function of high-z galaxies, compared with that of quasars, at magnitudes fainter than M1450 ~ -22 mag or zAB ~ 24 mag. Multi-wavelength follow-up studies of the discovered objects as well as further survey observations are ongoing.

    The European Agency for Safety and Health at Work (EU-OSHA) is developing an online e-guide, which will provide tips and practical information for each EU country (in their national language(s)) on ageing and occupational health and safety. The e-guide will be launched in 2016 as part of the EU-OSHA campaign on Healthy Workplaces for all ages. The e-guide will present evidence, tools and practical examples of how companies can take action and effectively promote sustainable employability. As part of the development of the e-guide, a cross-sectional study was conducted to survey Belgian employers in April 2015 to determine their specific needs concerning older workers' occupational health and safety issues. Researchers from Milieu Ltd. (Brussels, Belgium), the consultancy company coordinating the e-guide project, and Mensura Occupational Health Services (Brussels, Belgium) developed a 13-item questionnaire. The survey addressed the needs and importance given to sustainable employability of older workers in Belgian companies and evaluated corporate knowledge regarding relevant national policies. The questionnaire was distributed electronically to the management of 22,084 private-sector companies affiliated with Mensura. Ten percent (n = 2133) of recipients opened the e-mail, and 37 % (n = 790) of these completed the questionnaire. In 89 % of the responding companies, sustainable employability of workers aged ≥55 years plays an important role; 70 % have no active sustainable employability policy/initiative; 18 % experience difficulties promoting sustainable employability; and 86 % indicate no need for support to promote sustainable employability. Respondents noted the following health complaints among workers aged ≥55 years: work-related health problems (31 %), stress (26 %), work agreements/type of work (17 %), work/life balance (15 %), and career development and/or training (9 %).

    Full Text Available Inclusion is high on the agenda of school systems around the world. But what does “inclusion” mean? Do teachers really know what it is? Do they know what strategies to use in order to achieve it? This paper investigates some of the “myths” about this issue, highlighting that teachers are often in contradictory in what they state and what they actually do. Group-work is a typical inclusive strategy, yet often times disguises the weaker contributions of lower performing students while giving the impression that “everyone is taking part.” Peer-to-peer learning may be useful for the lower performing students but may also not add much to the best ones. Using the results from a survey of 258 respondents, including all teachers on the job, from all school grades, this paper provides useful findings in this regard. Additional considerations come from the authors’ experience with a three-year long national project about educational experiences and inclusion, called Learning4All - www.learningforall.it. This involved more than 250 teachers being interviewed in detail. The paper presents what teachers think and say about inclusion, what they do in the class and what they get, in terms of benefits, from the students.

    High turnover of nursing assistants (NAs) has implications for the quality of nursing home care. Greater understanding of correlates of NA turnover is needed to provide insight into possible retention strategies. This study examined nursing home organizational characteristics and specific job characteristics of staff in relation to turnover of NAs. Cross-sectional data on 944 nationally representative nursing homes were derived from the 2004 National Nursing Home Survey. Using a 3-month turnover rate, 25% of the facilities with the lowest turnover rates were classified as low turnover, 25% of the facilities with the highest turnover were classified as high turnover, and the remaining 50% of the facilities were classified as moderate turnover. Multinomial logistic regression was used to examine organizational and job characteristics associated with low and high turnover compared with moderate turnover. One organizational characteristic, staffing levels at or greater than 4.0 hours per patient day, was associated with greater odds of low NA turnover and reduced odds of high NA turnover. Job characteristics including higher wages and union membership were associated with greater odds of low NA turnover, whereas wages, fully paid health insurance, employee assistance benefits, and involvement in resident care planning were associated with reduced odds of high NA turnover. The results of this study suggest that job characteristics of NA staff may be particularly important for turnover. Specifically, the provision of competitive wages and benefits (particularly health insurance) and involvement of NAs in resident care planning could potentially reduce NA turnover, as could maintaining high levels of nurse staffing.

    We have analyzed spectra for all active galactic nuclei in the Rossi X-ray Timing Explorer (RXTE) archive. We present long-term average values of absorption, Fe line equivalent width, Compton reflection and photon index, as well as calculating fluxes and luminosities in the 2-10 keV band for 100 AGN with sufficient brightness and overall observation time to yield high quality spectral results. We compare these parameters across the different classifications of Seyferts and blazars. Our distributions of photon indices for Seyfert 1's and 2's are consistent with the idea that Seyferts share a common central engine, however our distributions of Compton reflection hump strengths do not support the classical picture of absorption by a torus and reflection off a Compton-thick disk with type depending only on inclination angle. We conclude that a more complex reflecting geometry such as a combined disk and torus or clumpy torus is likely a more accurate picture of the Compton-thick material. We find that Compton ref...

This study aimed to explore the knowledge and perception of senior medical students about the generic medicines. Methodology: A cross-sectional study was conducted among 237 senior medical students (final year students and interns using a validated self-administered questionnaire. The collected data were analyzed using Statistical Package for the Social Sciences version 20 for windows and comparison of difference was done using linear by linear association. A p value of less than 0.05 was taken as statistically significant. Results: The average age (standard deviation of the respondents was 23.54 (1.39 years. Almost 5% of respondents correctly answered the question regarding the regulatory limits for bioequivalence. Almost two-thirds of respondents correctly agreed that generic medicine is bioequivalent to a brand-name medicine, and 79.3% and 72.5% of respondents correctly agreed that the medicine should be present in the same dosage form and same dose, respectively, as the brand-name medicines. However, almost half of the respondents had impression that brand-name medicines are required to meet higher safety standard than generic medicines. Almost 90% of respondents felt that advertisement by the drug companies would influence the use of brand-name medicine and they need more information about generic medicine. Conclusion: This study highlights the negative perception and knowledge deficit among the respondents. The students’ responses to almost all the statements were almost similar to the respondents’ academic year (final year students and interns, gender and nationality.

    Triggering studies provide an important tool for understanding the fundamental physics of how faults slip and interact, and they also provide clues about the stress states of faults. In this study, we explore how seismic waves from the 27 February 2010 Mw8.8 Maule, Chile mainshock interact with the left lateral strike-slip Enriquillo-Plantain Garden Fault (EPGF) and surrounding reverse faults in the southern Haiti peninsula. The Chile mainshock occurred 6,000 km away and just 46 days after the 12 January 2010 Mw7.0 Haiti earthquake, a tragic event which activated multiple faults in the southern Haiti peninsula. During the surface waves of the Chile mainshock, several tectonic tremor signals were observed, originating from south of the EPGF trace. Cross-correlation of the triggered tremor and transient stresses resolved onto to the EPGF indicates that the Love wave of the Chile mainshock was the primary driving mechanism of the triggered deep shear slip and tremor signals, as opposed to dilatational stress changes generated by the Rayleigh wave. We also searched for any influence of transient stresses on Haiti aftershock activity by applying the matched filter technique to multiple days of seismic data around the time of the Chile mainshock. While we identified a slight increase in Haiti aftershock activity rate, the rate changes were significant only when small magnitude events were included in the significance tests. These observations are generally consistent with recent inferences that deep tectonic tremor is more sensitive than shallow earthquakes to external stress perturbations.

    Full Text Available We present here a review of the latest results on the spatially-resolved analysis of the stellar populations and ionized gas of disk-dominated galaxies based on Calar Alto Legacy Integral Field Area (CALIFA data. CALIFA is an ongoing integral field spectroscopy (IFS survey of galaxies in the Local Universe (0.005 < z < 0.03 that has already obtained spectroscopic information up to \\(\\sim\\2.5 \\(r_e\\ with a spatial resolution better than \\(\\sim\\1 kpc for a total number of more than 600 galaxies of different morphological types, covering the color-magnitude diagram up to M\\(_{\\rm R}<-\\18 mag. With nearly 2000 spectra obtained for each galaxy, CALIFA offers one of the best IFU datasets to study the star formation histories and chemical enrichment of galaxies. In this article, we focus on the main results from the analysis of the oxygen abundances based on the study of ionized gas in H II regions and individual spaxels and their relation to the global properties of galaxies, using an updated/revised dataset with more galaxies and ionized regions. In summary, we have confirmed previous published results indicating that: (1 the M-Z relation does not present a secondary relation to the star formation rate, when the abundance is measured at the effective radius; (2 the oxygen abundance presents a strong correlation with the stellar surface density (∑-Z relation; (3 the oxygen abundance profiles present three well-defined regimes: (i an overall negative radial gradient between 0.5 and 2 \\(r_e\\, with a characteristic slope of \\(\\alpha_{O/H}\\ \\(\\sim\\\\(-\\0.1 dex/\\(r_e\\; (ii a universal flattening beyond \\(>\\2 \\(r_e\\; and (iii an inner drop at \\(<\\0.5 \\(r_e\\ that depends on mass; (4 the presence of bending in the surface brightness profile of disk galaxies is not clearly related to either the change in the shape of the oxygen abundance profile or the properties of the underlying stellar population.

    I have used multi-epoch astrometry from the Wide-field Infrared Survey Explorer to perform a search for a distant companion to the Sun via its parallactic motion. I have not found an object of this kind down to W2 = 14.5. This limit corresponds to analogs of Saturn and Jupiter at 28,000 and 82,000 AU, respectively, according to models of the Jovian planets by Fortney and coworkers. Models of brown dwarfs by Burrows and coworkers predict fainter fluxes at a given mass for the age of the solar system, producing a closer distance limit of 26,000 AU for a Jupiter-mass brown dwarf. These constraints exclude most combinations of mass and separation at which a solar companion has been suggested to exist by various studies over the years.

    This article explores the discrimination practices encountered by lesbian, gay, bisexual, and transgender (LGBT) individuals in education, income, employment, and health care in Turkey. Limited quantitative data on LGBT individuals are available in Turkey. This study collected data from 2,875 LGBT individuals through a Web-based survey. The findings suggest that LGBT individuals report perceived direct and indirect discrimination in accessing education, employment, and health care. In a country where LGBT rights are not yet recognized and antidiscrimination legislation covering sexual orientation and gender identity is still nonexistent, findings demonstrate perceived discrimination of LGBTs rarely turns into a legal complaint. Even when they do, most LGBTs in our sample report that they did not feel that the justice system addressed their grievances.

    We present the survey design, data reduction, and spectral fitting pipeline for the VIRUS-P Exploration of Nearby Galaxies (VENGA). VENGA is an integral field spectroscopic survey, which maps the disks of 30 nearby spiral galaxies. Targets span a wide range in Hubble type, star formation activity, morphology, and inclination. The VENGA data-cubes have 5.6'' FWHM spatial resolution, ~5A FWHM spectral resolution, sample the 3600A-6800A range, and cover large areas typically sampling galaxies out to ~0.7 R_25. These data-cubes can be used to produce 2D maps of the star formation rate, dust extinction, electron density, stellar population parameters, the kinematics and chemical abundances of both stars and ionized gas, and other physical quantities derived from the fitting of the stellar spectrum and the measurement of nebular emission lines. To exemplify our methods and the quality of the data, we present the VENGA data-cube on the face-on Sc galaxy NGC 628 (a.k.a. M 74). The VENGA observations of NGC 628 are de...

    Transforming from retributivis to education doctrine is a significant symbol of modernization of penalty idea. To adapt to this change trend, community correction, which belongs to Measure of Security, was born at the right moment. It has been more than ten years from trial implementation to nationwide practice; however, it is rarely known that there is social survey before the application of community correction. At present, partial areas have attempted to carry out the pre-pleading social survey system. This system can be dated from the Survey System for Qualifications of Probation in the USA, and its theoretical supports are Three Factor Theory of Crime and Individual Penalty Theory. This system conforms to the trend that the penalty has become mitigation, humtheirity and education. However, at the same time,it also has many problems in the judicial practice. For instance, investigation in different areas is difficult, the degree of specialization for the survey estimator is low, people are unwilling to cooperate, investigation methods are too simple, investigation has become a mere formality, and survey assessment may not be adopted because it may involve character evidence. Such problems hinder the realization of the value of pre-pleading social survey system. Therefore, it is necessary to explore a reasonable path to realize the optimization of this system. It can be done from the following ways: establish cross-regional social survey coordination mechanism, specialize the investigation and evaluation team, strengthen the publicity of system, and bring in avoidance rules.%从报应主义转向教育主义是刑罚理念现代化的重要标志之一。为顺应此种发展趋势,社区矫正这一保安处分应运而生。在我国,社区矫正从部分地区试点到全国推行已十载有余,而适用社区矫正之前的社会调查工作仍鲜为人知。目前,部分地区已尝试推行了诉前社会调查制度,该制度肇始于美国的

    The value placed on types of evidence within decision-making contexts is highly dependent on individuals, the organizations in which the work and the systems and sectors they operate in. Decision-making processes too are highly contextual. Understanding the values placed on evidence and processes guiding decision-making is crucial to designing strategies to support evidence-informed decision-making (EIDM). This paper describes how evidence is used to inform local government (LG) public health decisions. The study used mixed methods including a cross-sectional survey and interviews. The Evidence-Informed Decision-Making Tool (EvIDenT) survey was designed to assess three key domains likely to impact on EIDM: access, confidence, and organizational culture. Other elements included the usefulness and influence of sources of evidence (people/groups and resources), skills and barriers, and facilitators to EIDM. Forty-five LGs from Victoria, Australia agreed to participate in the survey and up to four people from each organization were invited to complete the survey (n = 175). To further explore definitions of evidence and generate experiential data on EIDM practice, key informant interviews were conducted with a range of LG employees working in areas relevant to public health. In total, 135 responses were received (75% response rate) and 13 interviews were conducted. Analysis revealed varying levels of access, confidence and organizational culture to support EIDM. Significant relationships were found between domains: confidence, culture and access to research evidence. Some forms of evidence (e.g. community views) appeared to be used more commonly and at the expense of others (e.g. research evidence). Overall, a mixture of evidence (but more internal than external evidence) was influential in public health decision-making in councils. By comparison, a mixture of evidence (but more external than internal evidence) was deemed to be useful in public health decision

    Full Text Available Abstract Background It is a high priority that health care providers have effective communication skills. It has been well documented that the doctor-patient relationship is central to the delivery of high quality medical care, and it has been shown to affect patient satisfaction, to decrease the use of pain killers, to shorten hospital stays, to improve recovery from surgery and a variety of other biological, psychological and social outcomes. This study sought to quantify the current knowledge of interns in Iran about communication skills. Methods A cross-sectional study using a self-report questionnaire was conducted among interns. Data analysis was based on 223 questionnaires. The internal consistency of the items was 0.8979. Results Overall, knowledge levels were unsatisfactory. Results indicated that interns had a limited knowledge of communication skills, including identification of communication skills. In addition, there was a significant difference between the mean scores of interns on breaking bad news and sex education. The confidence of males about their communication skills was significantly higher than for females. Analysis of the total scores by age and sex showed that there was a statistically significant main effect for sex and the interaction with age was statistically significant. Free response comments of the interns are also discussed. Conclusions It is argued that there is a real need for integrating a communication skills course, which is linked to the various different ethnic and religious backgrounds of interns, into Iranian medical curricula. Some recommendations are made and the limitations of the study are discussed.

  1. Using Short Dietary Questions to Develop Indicators of Dietary Behaviour for Use in Surveys Exploring Attitudinal and/or Behavioural Aspects of Dietary Choices

    2015-08-01

    Full Text Available For countries where nutrition surveys are infrequent, there is a need to have some measure of healthful eating to plan and evaluate interventions. This study shows how it is possible to develop healthful eating indicators based on dietary guidelines from a cross sectional population survey. Adults 18 to 64 years answered questions about the type and amount of foods eaten the previous day, including fruit, vegetables, cereals, dairy, fish or meat and fluids. Scores were based on serves and types of food according to an established method. Factor analysis indicated two factors, confirmed by structural equation modeling: a recommended food healthful eating indicator (RF_HEI and a discretionary food healthful eating indicator (DF_HEI. Both yield mean scores similar to an established dietary index validated against nutrient intake. Significant associations for the RF_HEI were education, income, ability to save, and attitude toward diet; and for the DF_HEI, gender, not living alone, living in a socially disadvantaged area, and attitude toward diet. The results confirm that short dietary questions can be used to develop healthful eating indicators against dietary recommendations. This will enable the exploration of dietary behaviours for “at risk” groups, such as those with excess weight, leading to more relevant interventions for populations.

    We present the survey design, data reduction, and spectral fitting pipeline for the VIRUS-P Exploration of Nearby Galaxies (VENGA). VENGA is an integral field spectroscopic survey, which maps the disks of 30 nearby spiral galaxies. Targets span a wide range in Hubble type, star formation activity, morphology, and inclination. The VENGA data cubes have 5.''6 FWHM spatial resolution, ~5 Å FWHM spectral resolution, sample the 3600 Å-6800 Å range, and cover large areas typically sampling galaxies out to ~0.7R 25. These data cubes can be used to produce two-dimensional maps of the star formation rate, dust extinction, electron density, stellar population parameters, the kinematics and chemical abundances of both stars and ionized gas, and other physical quantities derived from the fitting of the stellar spectrum and the measurement of nebular emission lines. To exemplify our methods and the quality of the data, we present the VENGA data cube on the face-on Sc galaxy NGC 628 (a.k.a. M 74). The VENGA observations of NGC 628 are described, as well as the construction of the data cube, our spectral fitting method, and the fitting of the stellar and ionized gas velocity fields. We also propose a new method to measure the inclination of nearly face-on systems based on the matching of the stellar and gas rotation curves using asymmetric drift corrections. VENGA will measure relevant physical parameters across different environments within these galaxies, allowing a series of studies on star formation, structure assembly, stellar populations, chemical evolution, galactic feedback, nuclear activity, and the properties of the interstellar medium in massive disk galaxies.

    The Manufacturers of geophysical instruments have been facing these past decades the fast evolution of the electronics and of the computer sciences. More automatisms have been introduced into the equipment and into the processing and interpretation software which may let believe that conducting geophysical surveys requires less understanding of the method and less experience than in the past. Hence some misunderstandings in the skills that are needed to make the geophysical results well integrated among the global information which the applied geologist needs to acquire to be successful in his applications. Globally, the demand in geophysical investigation goes towards more penetration depth, requiring more powerful transmitters, and towards a better resolution, requiring more data such as in 3D analysis. Budgets aspects strongly suggest a high efficiency in the field associated to high speed data processing. The innovation is required in all aspects of geophysics to fit with the market needs, including new technological (instruments, software) and methodological (methods, procedures, arrays) developments. The structures in charge of the geophysical work can be public organisations (institutes, ministries, geological surveys,…) or can come from the private sector (large companies, sub-contractors, consultants, …), each one of them getting their own constraints in the field work and in the processing and interpretation phases. In the applications concerning Groundwater investigations, Mining Exploration, Environmental and Engineering surveys, examples of data and their interpretation presently carried out all around the world will be presented for DC Resistivity (Vertical Electrical Sounding, 2D, 3D Resistivity Imaging, Resistivity Monitoring), Induced Polarisation (Time Domain 2D, 3D arrays for mining and environmental), Magnetic Resonance Sounding (direct detection and characterisation of groundwater) and Electromagnetic (multi-component and multi

    Full Text Available  The paper is a part of a research on Angevin Gothic buildings in Naples. The aim is to define a methodological path to understand Gothic in Naples in relation to the original French models. The Church of S.Eligio, built in 1270 by Charles I of Anjou, is one of the most important buildings to reconstruct the development of Gothic in Naples. Through the study of archival records and the survey, aimed at defining the exact geometric configuration, the goal was to reconstruct the evolution of the building, to identify existing and alleged regulator lines. In our research we tested Automated immage based modeling, techniques based on the use of photographic images for 3D data collection, to formulate and verify hypotheses, to compare the geometric configuration with the theoretical models, to analyze the layers and to reveal the regulator lines

    Near-Earth objects (NEOs) are small solar system bodies whose orbits bring them close to the Earth’s orbit. We are carrying out a Warm Spitzer Cycle 11 Exploration Science program entitled NEOSurvey—a fast and efficient flux-limited survey of 597 known NEOs in which we derive a diameter and albedo for each target. The vast majority of our targets are too faint to be observed by NEOWISE, though a small sample has been or will be observed by both observatories, which allows for a cross-check of our mutual results. Our primary goal is to create a large and uniform catalog of NEO properties. We present here the first results from this new program: fluxes and derived diameters and albedos for 80 NEOs, together with a description of the overall program and approach, including several updates to our thermal model. The largest source of error in our diameter and albedo solutions, which derive from our single-band thermal emission measurements, is uncertainty in η, the beaming parameter used in our thermal modeling; for albedos, improvements in solar system absolute magnitudes would also help significantly. All data and derived diameters and albedos from this entire program are being posted on a publicly accessible Web page at nearearthobjects.nau.edu.

    Evaluating the susceptibility related to occurrence of sinkholes is of particular relevance in coastal settings, due to the likely high frequency of sinkholes, that are especially favored by the interaction between fresh and brackish water, with the consequent strong aggressivity on the soluble rock masses. Long stretches of the Ionian coastline (southern Apulia, SE Italy) are affected by sinkholes, that in more than one occasion have caused significant damage and problems to the human infrastructures, and in particular to the main communication routes in the area. In this study, we combine the outcomes of different methodologies to reach a good understanding of the sinkhole susceptibility in the area of Torre Castiglione, in the proximity of Porto Cesareo (Lecce province): starting from geological analysis, and the building up of a detailed database on the sinkholes in the study area, the obtained data were used to plan the following research, consisting of geophysical surveys, that were carried out with different techniques. At the same time, cave explorations (including scuba-diving) were performed in one of the most important sinkhole at Torre Castiglione: this phase of the activity allowed to get remarkable insights into the features of the submerged karst systems in the area. Flooded passages, 4 to 9 mt-wide and 5,5 mt-high, were explored for several tens of meters. A chaotic jumble of breakdown deposits constitute the cave pavement, and the vault and walls of the passages are heavily fractured, pointing out to the possibility of further detachments, which likely will result in opening additional sinkholes at the surface. The underground systems appear to be quite complex and extensive, but the difficulty in the explorations (mostly due to narrowing of the passages and to the rock mass instability) suggested to stop the scuba-diving activity for safety reasons. Sinkholes detection and imaging is a challenging task for geophysical methods, not only because of

    This cross-sectional survey assessed the characteristics of labels of follow-up formula (FUF) and growing-up milk (GUM) compared with infant formula (IF), including cross-promotion practices between FUF/GUM and IF manufactured by the same company, sold in Phnom Penh, Cambodia; Kathmandu Valley, Nepal; Dakar Department, Senegal; and Dar es Salaam, Tanzania. All products were imported. A wide recommended age/age range for introduction was provided by manufacturers across all sites, with products with an age recommendation of 0-6 months being most prevalent in three sites, representing over a third of all products. Various age categories (e.g. 1, 1+ and Stage 1) commonly appeared on labels. A number of descriptive names (e.g. infant formula and milk formula) per category of age of introduction were used with some appearing across more than one category. Images of feeding bottles were found on most labels across all age categories, but prevalence decreased with older age categories. The majority of FUF/GUM manufactured by IF companies across all sites displayed at least one example of cross-promotion with one or more of the company's IF: two-thirds or more contained similar colour schemes/designs and similar brand names; 20-85% had similar slogans/mascots/symbols. A wide and potentially confusing range of ages/categories of introduction and descriptive names were found, and cross-promotion with IF was common on FUF/GUM labels. Global guidance from normative bodies forms the basis of most low and middle income countries policies and should provide specific guidance to prohibit cross-promotion between FUF/GUM and IF, and all three categories should be classified as breastmilk substitutes.

    We present an investigation of the globular cluster (GC) systems of NGC 3607 and NGC 3608 as part of the ongoing SLUGGS survey. We use wide-field imaging data from the Subaru telescope in the g, r, and i filters to analyse the radial density, colour and azimuthal distributions of both GC systems. With the complementary kinematic data obtained from the Keck II telescope, we measure the radial velocities of a total of 81 GCs. Our results show that the GC systems of NGC 3607 and NGC 3608 have a detectable spatial extent of ~ 15, and 13 galaxy effective radii, respectively. Both GC systems show a clear bimodal colour distribution. We detect a significant radial colour gradient for the GC subpopulations in both galaxies. NGC 3607 exhibits an overabundance of red GCs on the galaxy minor axis and NGC 3608 shows a misalignment in the GC subpopulation position angles with respect to the galaxy stellar component. With the aid of literature data, we discuss several relationships between the properties of GC systems and ...

    Objective. The objective of this survey was to explore the attitudes towards plagiarism of faculty members and medical students in Pakistan. Methods. The Attitudes Toward Plagiarism questionnaire (ATP) was modified and distributed among 550 medical students and 130 faculty members in 7 medical colleges of Lahore and Rawalpindi. Data was entered in the SPSS v.20 and descriptive statistics were analyzed. The questionnaire was validated by principal axis factoring analysis. Results. Response rate was 93% and 73%, respectively. Principal axis factoring analysis confirmed one factor structure of ATP in the present sample. It had an acceptable Cronbach's alpha value of 0.73. There were 421 medical students (218 (52%) female, 46% 3rd year MBBS students, mean age of 20.93 ± 1.4 years) and 95 faculty members (54.7% female, mean age 34.5 ± 8.9 years). One fifth of the students (19.7%) trained in medical writing (19.7%), research ethics (25.2%) or were currently involved in medical writing (17.6%). Most of the faculty members were demonstrators (66) or assistant professors (20) with work experience between 1 and 10 years. Most of them had trained in medical writing (68), research ethics (64) and were currently involved in medical writing (64). Medical students and faculty members had a mean score of 43.21 (7.1) and 48.4 (5.9) respectively on ATP. Most of the respondents did not consider that they worked in a plagiarism free environment and reported that self-plagiarism should not be punishable in the same way as plagiarism. Opinion regarding leniency in punishment of younger researchers who were just learning medical writing was divided. Conclusions. The general attitudes of Pakistani medical faculty members and medical students as assessed by ATP were positive. We propose training in medical writing and research ethics as part of the under and post graduate medical curriculum.

    Aim of this paper is to report the results of a pilot study as a part of a program addressed to health promotion and to improve the culture of sustainability in the school. A 15-items structured questionnaire was administered to 1 011 students (aged 9-18 years) in order to explore the entity of the phenomenon of mobile telephony among the young and qualitatively esteem the level of exposure to the potential adverse health and social effects of such dominant form of electronically mediate communication. This preliminary information was then deepened by in-group interviews focused to clarify the cultural basis of the phenomenon. The survey-study confirmed that the penetration of mobile telephony among the young matches with the national trend: 96% of 14-18-teens own at least one mobile phone; 22% of them own multiple mobile phones. In addition, most of them use mobile phone all the day; a third makes calls over 6 minutes long; half is poorly informed about the potential health risks related to ''electromagnetic pollution''. Despite the most perceive mobile phone like something noxious, only 23% holds it far from body; a very small percentage uses a hands-free kit. Most declared to suffer from a sort of addiction towards mobile phone. In the light of a growing literature and of a supposed more vulnerability of children and adolescents towards toxicants than adults, we believe that health and school operators should inform parents and the young about the possible risks linked to the abuse of technology and promote a more critic and responsible approach to mobile phone.

    The relationship between social class and mental illness stigma has received little attention in recent years. At the same time, the concept of mental health literacy has become an increasingly popular way of framing knowledge and understanding of mental health issues. British Social Attitudes survey data present an opportunity to unpack the relationships between these concepts and social class, an important task given continuing mental health inequalities. Regression analyses were undertaken which centred on depression and schizophrenia vignettes, with an asthma vignette used for comparison. The National Statistics Socio-economic Classification, education and income were used as indicators of class. A number of interesting findings emerged. Overall, class variables showed a stronger relationship with mental health literacy than stigma. The relationship was gendered such that women with higher levels of education, especially those with a degree, had the lowest levels of stigma and highest levels of mental health literacy. Interestingly, class showed more of an association with stigma for the asthma vignette than it did for both the depression and schizophrenia vignettes, suggesting that mental illness stigma needs to be contextualised alongside physical illness stigma. Education emerged as the key indicator of class, followed by the National Statistics Socio-economic Classification, with income effects being marginal. These findings have implications for targeting health promotion campaigns and increasing service use in order to reduce mental health inequalities. © The Author(s) 2014.

    Spatial disorientation (SD) is one of the most severe causative factors in aviation accidents. We analyzed the reported SD episodes to evaluate the characteristics of severe SD in fighter pilots. Three hundred seventeen cases (95.5%) of 332 total valid cases experienced SD, and the ratio of night and day SD experiences (52.7% vs. 47.3%) (p < 0.05) shows a clear prevalence of night SD events. The severity of SD episodes at night (2.23 +/- 1.09) was higher than at day (1.89 +/- 1.04) (p < 0.01). In addition, the severity of visual illusions was significantly higher at night. A significant difference was found for meteorological conditions, such as visual meteorological conditions (VMC), instrument meteorological conditions (IMC) and VMC-IMC (VI) transition, among times of days. In conclusion, the severity of the SD episodes was higher at night. This may be due to an increase in visual severe SD episodes at night.

    Evidence is accumulating on the impact of the recent economic crisis on health and health systems across Europe. However, little is known about the effect this is having on physicians - a crucial resource for the delivery of healthcare services. This paper explores the adaptation to the crisis of public sector physicians and their ability to keep performing their functions, with the objective of gaining a better understanding of health workers' resilience under deteriorating conditions. We conducted a survey among 484 public primary care and hospital physicians in Portugal's capital city area and explored their perceptions of the crisis, adaptation and coping strategies. We used ordinal and logistic regression models to link changes in hours worked and intentions to migrate with physicians' characteristics and specific answers. We found little evidence of physicians changing their overall allocation of working time before and after the crisis, with their age, types of specialisation, valuation of job flexibility and independence significantly associated with changes in public sector hours between 2010 and 2015. Being divorced, not Portuguese, of younger age, and working a high number of hours per week, were found to increase the probability of physicians considering migration, the same as having a poor opinion of recent government health policies. On the other hand, enjoying their current working environment, not wanting to disrupt provision of service, and leisure time were found to protect against scaling down public sector hours or considering migration. Our work on Portuguese physicians contributes to the debate on health workers' resilience, showing the value of understanding the influence of personal characteristics and opinions on their adaptation to changing circumstances, before designing policies to improve their working conditions and retention.

    Suites of new geophysical and geochemical exploration surveys were conducted to provide evidence for geothermal resource at the Haleakala Southwest Rift Zone (HSWRZ) on Maui Island, Hawai’i. Ground-based gravity (~400 stations) coupled with heli-bourne magnetics (~1500 line kilometers) define both deep and shallow fractures/faults, while also delineating potentially widespread subsurface hydrothermal alteration on the lower flanks (below approximately 1800 feet a.s.l.). Multi-level, upward continuation calculations and 2-D gravity and magnetic modeling provide information on source depths, but lack of lithologic information leaves ambiguity in the estimates. Additionally, several well-defined gravity lows (possibly vent zones) lie coincident with magnetic highs suggesting the presence of dike intrusions at depth which may represent a potentially young source of heat. Soil CO2 fluxes were measured along transects across geophysically-defined faults and fractures as well as young cinder cones along the HSWRZ. This survey generally did not detect CO2 levels above background, with the exception of a weak anomalous flux signal over one young cinder cone. The general lack of observed CO2 flux signals on the HSWRZ is likely due to a combination of lower magmatic CO2 fluxes and relatively high biogenic surface CO2 fluxes which mix with the magmatic signal. Similar surveys at the Puna geothermal field on the Kilauea Lower East Rift Zone (KLERZ) also showed a lack of surface CO2 flux signals, however aqueous geochemistry indicated contribution of magmatic CO2 and He to shallow groundwater here. As magma has been intercepted in geothermal drilling at the Puna field, the lack of measured surface CO2 flux indicative of upflow of magmatic fluids here is likely due to effective “scrubbing” by high groundwater and a mature hydrothermal system. Dissolved inorganic carbon (DIC) concentrations, δ13C compositions and 3He/4He values were sampled at Maui from several shallow

    Although human factors are important in terms of patient safety, there have been very few reports on the attitudes of healthcare professionals working in acute care settings in South Korea. In the present study, we investigated the attitudes of such professionals, their cultures and their management systems. A questionnaire survey with 65 items covering nine themes affecting patient safety. Nine themes were compared via a three-or-more-way analysis of variance, with interaction, followed by multiple comparisons among several groups. Intensive care units, emergency departments and surgical units of nine urban hospitals. 592 nurses and 160 physicians. None. Mean scores using a five-point scale and combined response scores for each of the nine themes. The mean score for information-sharing was the highest (3.78±0.49) and that for confidence/assertion was the lowest (2.97±0.34). The mean scores for teamwork, error management, work value, organisational climate, leadership, stress and fatigue level, and error/procedural compliance were intermediate. Physicians showed lower scores in leadership and higher scores in information-sharing than nurses. Respondents with 24 months or less of a clinical career showed higher scores in leadership, stress and fatigue, and error scores and lower scores in work value than more experienced respondents. Our results suggest that medical personnel in Korea are relatively reluctant to disclose error or assert their different opinions with others. Many did not adequately recognise the negative effects of fatigue and stress, attributed errors to personal incompetence, and error-management systems were inadequate. Discrepancies in leadership and information-sharing were evident between professional groups, and leadership, stress, fatigue level, work value and error scores varied with the length of work experience. These can be used as baseline data to establish training programmes for patient safety in Korea. Published by the BMJ

    Full Text Available Abstract Background The health information needs of developing countries increasingly include population-based estimates determined by biological and physiological measures. Collection of data on these biomarkers requires careful reassessment of ethical standards and procedures related to issues of safety, informed consent, reporting, and referral policies. This paper reviews the survey practices of health examination surveys that have been conducted in developed nations and discusses their application to similar types of surveys proposed for developing countries. Discussion The paper contends that a unitary set of ethical principles should be followed for surveys around the world that precludes the danger of creating double standards (and implicitly lowers standards for work done in developing countries. Global ethical standards must, however, be interpreted in the context of the unique historical and cultural context of the country in which the work is being done. Factors that influence ethical considerations, such as the relationship between investigators in developed and developing countries are also discussed. Summary The paper provides a set of conclusions reached through this discussion and recommendations for the ethical use of biomarkers in populations-based surveys in developing countries.

    Empirical studies suggest that consumption is more sensitive to current income than suggested under the permanent income hypothesis, which raises questions regarding expectations for future income, risk aversion, and the role of economic confidence measures. This report surveys a body of fundamental economic literature as well as burgeoning computational modeling methods to support efforts to better anticipate cascading economic responses to terrorist threats and attacks. This is a three part survey to support the incorporation of models of economic confidence into agent-based microeconomic simulations. We first review broad underlying economic principles related to this topic. We then review the economic principle of confidence and related empirical studies. Finally, we provide a brief survey of efforts and publications related to agent-based economic simulation.

  2. The Impact of Carsharing on Public Transit and Non-Motorized Travel: An Exploration of North American Carsharing Survey Data

    Full Text Available By July 2011, North American carsharing had grown to an industry of nearly 640,000 members since its inception on the continent more than 15 years ago. Carsharing engenders changes in member travel patterns both towards and away from public transit and non-motorized modes. This study, which builds on the work of two previous studies, evaluates this shift in travel based on a 6281 respondent survey completed in late-2008 by members of major North American carsharing organizations. Across the entire sample, the results showed an overall decline in public transit use that was statistically significant, as 589 carsharing members reduced rail use and 828 reduced bus use, while 494 increased rail use and 732 increased bus use. Thus for every five members that use rail less, four members use rail more, and for every 10 members that ride a bus less, almost nine members ride the bus more. The people increasing and decreasing their transit use are fundamentally different in terms of how carsharing impacts their travel environment. This reduction, however, is also not uniform across all organizations; it is primarily driven by a minority (three of eleven of participating organizations. At the same time, members exhibited a statistically significant increase in travel by walking, bicycling, and carpooling. Across the sample, 756 members increased walking versus a 568 decrease, 628 increased bicycling versus a 235 decrease, and 289 increased carpooling versus a decrease of 99  study participants. The authors found that 970 members reduced their auto commuting to work, while 234 increased it. Interestingly, when these shifts are combined across modes, more people increased their overall public transit and non-motorized modal use after joining carsharing than decreased it. Data collected on the commute distance of respondents found that carsharing members tend to have shorter commutes than most people living in the same zip code. The analysis also evaluates

    Changes of land use without a correct planning may produce its deterioration with their social, economical and environmental irreversible consequences over short to medium time range. In Argentina, the expansion of soybean fields induced a reduction of the area of pastures dedicated to stockbreeding. As cattle activity is being progressively concentrated on small pens, at feedlots farms, problems of soil and water pollution, mainly by nitrate, have been detected. The characterization of the spatial and temporal variability of soil water content is very important because the mostly advective transport of solutes. To avoid intensive soil samplings, very expensive, one has to recur to geophysical exploration methods. The objective of this work was to identify risk areas within a feedlot of the NW zone of Buenos Aires Province, in Argentina through geophysical methods. The surveys were carried out with an electromagnetic induction profiler EMI-400 (GSSI) and a Time domain Reflectometry (TDR) survey of depth 0-0.10 m with soil sampling and measurement of moisture content with gravimetric method (0-1.0 m). Several trenches were dug inside the pens and also at a test site, where texture, apparent density, saturated hydraulic conductivity (Ks), electrical conductivity of the saturation paste extract and organic matter content (OM) were measured. The water retention curves for these soils were also determined. At one of the pens undisturbed soil columns were extracted at 3 locations. Laboratory analysis for 0-1.0 m indicated that soil texture was classified as sandy loam, average organic matter content (OM) was greater than 2.3% with low values of apparent density in the first 10 cm. The range of spatial dependence of data suggested that the number of soil samples could be reduced. Soil apparent electrical conductivity (ECa) and soil moisture were well correlated and indicated a clear spatial pattern in the corrals. TDR performance was acceptable to identify the spatial

    The field of health communication has seen substantial growth in recent years, but existing health communication research literature contains little information on individuals who practice health communication in applied settings. This study reports the results of a national survey that targeted the alumni of 5 institutions that offer a master's degree in health communication. Of the 522 total graduates to whom the survey was sent, 398 responded. Survey results provided information in a number of areas including undergraduate education background; criteria used to determine what type of master's degree in health communication to pursue; strategies used to gain employment; employment sector of first job after graduation; salaries received after completion of a master's degree in health communication; satisfaction with career choice after completion of master's degree; satisfaction with type of master's degree in health communication received; satisfaction with career choice after completion of master's degree; and the degree to which respondents felt their master's program in health communication prepared them to meet core competencies in the field. These findings have significant implications for the health communication field and the programs that prepare individuals for a career as a health communication practitioner.

    Objectives Despite lumbar degenerative disc disease (LDDD) being significantly associated with non-specific low back pain and effective treatment remaining elusive, specialist multidisciplinary clinical stakeholder opinion remains unexplored. The present study examines the views of such experts. Design A reliable and valid electronic survey was designed to establish trends using theoretical constructs relating to current assessment and management practices. Clinicians from the Society of Back Pain Research (SBPR) UK were invited to take part. Quantitative data were collated and coded using Bristol Online Surveys (BOS) software, and content analysis was used to systematically code and categorise qualitative data. Setting Specialist multidisciplinary spinal interest group in the UK. Participants 38/141 clinically active, multidisciplinary SBPR members with specialist spinal interest participated. Among them, 84% had >9 years postgraduate clinical experience. Interventions None. Outcome measures Frequency distributions were used to establish general trends in quantitative data. Qualitative responses were coded and categorised in relation to each theme and percentage responses were calculated. Results LDDD symptom recurrence, in the absence of psychosocial influence, was associated with physical signs of joint stiffness (26%), weakness (17%) and joint hypermobility (6%), while physical factors (21%) and the ability to adapt (11%) were postulated as reasons why some experience pain and others do not. No one management strategy was supported exclusively or with consensus. Regarding effective modalities, there was no significant difference between allied health professional and medic responses (p=0.1–0.8). The future of LDDD care was expressed in terms of improvements in patient communication (35%), patient education (38%) and treatment stratification (24%). Conclusions Results suggest that multidisciplinary expert spinal clinicians appear to follow UK

    Full Text Available Objective. This work sought to analyze the use of Information and Communication Technologies (ICTs and social networks among the university nursing faculty staff in Spain. Methodology. This was a descriptive, cross-sectional study using a questionnaire on ICT skills designed to comply with the research objective, which was evaluated by experts and which was subjected to exploratory analysis of principal components; the reliability of this instrument measured with Cronbach's alpha was 0.85. The information technology tool used to publish the questionnaire on line was Limesurvey. The sample comprised 165 professors from 25 Nursing Faculties and Schools from universities in Spain. Results. Seventy one percent of the total surveyed used internet services to look for information, 63% used the internet as a means for formation and learning, and 72% used it as a communication platform (e-mail and virtual platforms like Sakai and Moodle. Although 51% of the teaching staff surveyed had more than 120 students registered in their courses, hypothesis testing revealed that the number of students in class is not a determining factor for the teaching staff to have greater interest to update its knowledge in ICTs. Younger professors use new technologies more profusely and the most-valued advantage of using ICTs was quick access to information. Professors perceive that after the Bologna Declaration, which requires modifying their teaching-learning processes through the new teaching methodologies, a drop has been produced in their performance and that of their peers in their area of knowledge. Conclusion. The nursing teaching staff is making strong efforts to confront the new challenges posed by ICTs to train the professionals of the 21st century. It is fundamental to pay special attention to improving the university teaching staff's skills in managing ICTs, promoting the implementation of the knowledge acquired.

    A reconnaissance of the geological literature on large regions of exposed crystalline rocks in the United States provides the basis for evaluating if any of those regions warrant further exploration toward identifying potential sites for development of a high-level radioactive waste repository. The reconnaissance does not serve as a detailed evaluation of regions or of any smaller subunits within the regions. Site performance criteria were selected and applied insofar as a national data base exists, and guidelines were adopted that relate the data to those criteria. The criteria include consideration of size, vertical movements, faulting, earthquakes, seismically induced ground motion, Quaternary volcanic rocks, mineral deposits, high-temperature convective ground-water systems, hydraulic gradients, and erosion. Brief summaries of each major region of exposed crystalline rock, and national maps of relevant data provided the means for applying the guidelines and for recommending regions for further study. It is concluded that there is a reasonable likelihood that geologically suitable repository sites exist in each of the major regions of crystalline rocks. The recommendation is made that further studies first be conducted of the Lake Superior, Northern Appalachian and Adirondack, and the Southern Appalachian Regions. It is believed that those regions could be explored more effectively and suitable sites probably could be found, characterized, verified, and licensed more readily there than in the other regions.

    Systematic collection of national agricultural data has been neglected in many low- and middle-income countries for the past 20 years. Commonly conducted nationally representative household surveys collect substantial quantities of highly underutilized food crop production data. To demonstrate the potential usefulness of commonly available household survey databases for analyzing the agriculture-nutrition nexus. Using household data from the 2010 Bangladesh Household Income and Expenditure Survey, the role and significance of crop selection, area planted, yield, nutrient production, and the disposition of 34 food crops in affecting the adequacy of farming households' nutrient availability and nutrient intake status are explored. The adequacy of each farming household's available energy, vitamin A, calcium, iron, and zinc and households' apparent intakes and intake adequacies are estimated. Each household's total apparent nutrient intake adequacies are estimated, taking into account the amount of each crop that households consume from their own production, together with food purchased or obtained from other sources. Even though rice contains relatively small amounts of micronutrients, has relatively low nutrient density, and is a relatively poor source of nutrients compared with what other crops can produce on a given tract of land, because so much rice is produced in Bangladesh, it is the source of 90% of the total available energy, 85% of the zinc, 67% of the calcium, and 55% of the iron produced by the agricultural sector. The domination of agriculture and diet by rice is a major constraint to improving nutrition in Bangladesh. Simple examples of how minor changes in the five most common cropping patterns could improve farming households' nutritional status are provided. Household surveys' agricultural modules can provide a useful tool for better understanding national nutrient production realities and possibilities.

    Full Text Available The Internet has changed media fandom in two main ways: it helps fans connect with each other despite physical distance, leading to the formation of international fan communities; and it helps fans connect with the creators of the TV show, deepening the relationship between TV producers and international fandoms. To assess whether Italian fan communities active online are indeed part of transnational online communities and whether the Internet has actually altered their relationship with the creators of the original text they are devoted to, qualitative analysis and narrative interviews of 26 Italian fans of American TV shows were conducted to explore the fan-producer relationship. Results indicated that the online Italian fans surveyed preferred to stay local, rather than using geography-leveling online tools. Further, the sampled Italian fans' relationships with the show runners were mediated or even absent.

    The James Webb Space Telescope’s Medium Resolution Spectrometer (MRS), will offer nearly two orders of magnitude improvement in sensitivity and >3× improvement in spectral resolution over our previous space-based mid-IR spectrometer, the Spitzer IRS. In this paper, we make predictions for spectroscopic pointed observations and serendipitous detections with the MRS. Specifically, pointed observations of Herschel sources require only a few minutes on source integration for detections of several star-forming and active galactic nucleus lines, out to z = 3 and beyond. But the same data will also include tens of serendipitous 0 ≲ z ≲ 4 galaxies per field with infrared luminosities ranging ∼106–1013 L ⊙. In particular, for the first time and for free we will be able to explore the L IR star formation rate function. The above conclusions hold for a wide range in the potential low-L end of the IR luminosity function, and account for the PAH deficit in low-L, low-metallicity galaxies.

  8. Volumetric Survey Speed: A Figure of Merit for Transient Surveys

    CERN Document Server

    Bellm, Eric C

    2016-01-01

    Time-domain surveys can exchange sky coverage for revisit frequency, complicating the comparison of their relative capabilities. By using different revisit intervals, a specific camera may execute surveys optimized for discovery of different classes of transient objects. We propose a new figure of merit, the instantaneous volumetric survey speed, for evaluating transient surveys. This metric defines the trade between cadence interval and snapshot survey volume and so provides a natural means of comparing survey capability. The related metric of areal survey speed imposes a constraint on the range of possible revisit times: we show that many modern time-domain surveys are limited by the amount of fresh sky available each night. We introduce the concept of "spectroscopic accessibility" and discuss its importance for transient science goals requiring followup observing. We present an extension of the control time algorithm for cases where multiple consecutive detections are required. Finally, we explore how surv...

    Anxiety and depression are common in the perinatal period. Telephone interventions, including telephone peer support and counselling, have been developed to support those experiencing perinatal mental illness. PANDA Post and Antenatal Depression Association provides support to women and men experiencing perinatal mental illness via the Australian National Perinatal Depression Helpline, encompassing both volunteer peer support and professional counselling. This study aimed to explore the experiences of callers to the Helpline. A cross-sectional survey design was used. All new callers from 1(st) May to 30(th) September 2013 were invited to participate. The survey, adapted from a previous survey of PANDA callers, included 23 questions using Likert-type scales, demographic and open-ended questions. Thematic network analysis was undertaken for responses to open-ended questions. 124 responses were received (124/405; 30% response). The majority of callers had called the Helpline regarding themselves (90%), with over one third (33%) of all callers seeking crisis support and help. Ninety-nine per cent of respondents 'agreed' or 'strongly agreed' that staff and/or volunteers understood their concerns, and 97% 'agreed' or 'strongly agreed' that overall PANDA had helped them. Callers described the PANDA service as uniquely tailored to the perinatal period, providing accessible, non-judgemental understanding and support, with a global theme from open-ended comments describing PANDA as 'a safe space to be heard and receive support without judgement'. Recommendations for service changes included increased hours of availability. Callers reported positive experiences of accessing support from the PANDA National Perinatal Depression Helpline. The Helpline was described as an accessible and acceptable telephone support for individuals experiencing perinatal mental illness. Recommendations for changes to the service included an increase in hours of operation to enable greater

    To test whether the proposed features of the Obstetric Transition Model-a theoretical framework that may explain gradual changes that countries experience as they eliminate avoidable maternal mortality-are observed in a large, multicountry, maternal and perinatal health database; and to discuss the dynamic process of maternal mortality reduction using this model as a theoretical framework. This was a secondary analysis of a cross-sectional study by the World Health Organization that collected information on more than 300 000 women who delivered in 359 health facilities in 29 countries in Africa, Asia, Latin America, and the Middle East, during a 2-4-month period in 2010-2011. The ratios of Potentially Life-Threatening Conditions, Severe Maternal Outcomes, Maternal Near Miss, and Maternal Death were estimated and stratified by stages of obstetric transition. The characteristics of each stage are defined. Data from 314 623 women showed that female fertility, indirectly estimated by parity, was higher in countries at a lower obstetric transition stage, ranging from a mean of 3 children in Stage II to 1.8 children in Stage IV. Medicalization increased with obstetric transition stage. In Stage IV, women had 2.4 times the cesarean deliveries (15.3% in Stage II and 36.7% in Stage IV) and 2.6 times the labor inductions (7.1% in Stage II and 18.8% in Stage IV) as women in Stage II. The mean age of primiparous women also increased with stage. The occurrence of uterine rupture had a decreasing trend, dropping by 5.2 times, from 178 to 34 cases per 100 000 live births, as a country transitioned from Stage II to IV. This analysis supports the concept of obstetric transition using multicountry data. The Obstetric Transition Model could provide justification for customizing strategies for reducing maternal mortality according to a country's stage in the obstetric transition.

    The basic survey for coal mine development was conducted in the Banjarsari area of Tanjungenim, Sumatra, Indonesia. In the survey, Japan deals with ground surface exploration, borehole physical survey, VSP survey and seismic survey, and Indonesia exploratory drilling, topographical mapping, measurement, hydrologic/hydraulic survey, access road formation, etc. The boreholes drilled are 35 in number and 4004m in total drilling length. The borehole physical survey was conducted in all 35 holes. The seismic survey was conducted on 5 traverse lines and in a total length of 10.19km, and the VSP survey in two boreholes. As a result of the survey, it was found out that there existed a large amount of coal reserve in a comparatively shallow area in the south-central part of the Banjarsari area. There exist faults, which has no great effects on the open pit mining. There is a high possibility of developing large-scale coal mines of open pit mining type with a comparatively low soil removing ratio. Concerning the coal quality, the heating value is comparatively low, the latter half of a 4000 kcal/kg level. It can be expected to realize a pit-mouth power plant which is low in coal carrying cost. 129 figs., 28 tabs.

    With the growing recognition of the critical role that risk communication plays in a public health emergency, a number of articles have provided prescriptive best practices to enhance such communication. However, little empirical research has examined perceptions of the quality of communication, the impact of uncertainty on changing communication, use of information sources, and trust in specific government spokespersons. Similarly, although there is significant conceptual focus on trust and communication as important in vaccination intent and acceptance, little research has explored these relationships empirically. We conducted an online survey in late January 2010 with a nationally representative sample (N=2,079) that included Hispanic and African American oversamples. The completion rate was 56%. We found that public health officials were the most trusted spokespersons, with President Obama being the most highly trusted elected official. Demographic variables, including race, accounted for 21% of the variance in trust of the president. Perceptions of the quality of communication were high, including significant understanding of uncertainty and appreciation for officials' openness about evolving information. Other factors that contributed to vaccination acceptance were quality of communication, closely following the news, and confidence in the vaccine because of a role model effect of the Obama daughters' immunizations; these factors significantly increased trust in government actions. Because the challenges of communication often vary over the course of a pandemic, there is a consistent need to pay close attention to both communication content and delivery and prepare public health officials at all levels to be effective communicators.

In this issue we feature school libraries and their connection to evidence based practice. Former Editor-in-Chief, Lindsay Glynn, began putting the wheels in motion for this feature almost a year ago. She invited Carol Gordon and Ross Todd to act as guest editors of the section, drawing upon their contacts and previous work in this field. The result is an issue with five feature articles exploring different aspects of the connection between school libraries and evidence based practice, from the theoretical to the practical. In addition, there is a thought-provoking Commentary by David Loertscher, asking whether we need the evolutionary model of evidence based practice, or something more revolutionary!In addition to the Feature section, we have a well-rounded issue with articles on the topics of library human resources, and the development of a scholars’ portal.

    In response to severe flooding in November 2006, the National Park Service contracted for a high-resolution aerial Light Detection and Ranging (LiDAR) topographic survey of Mount Rainier National Park, Washington. Due to inclement weather, this survey was performed in two stages: early September 2007 and September-October 2008. The total surveyed area of 241,585 acres includes an approximately 100-m-wide buffer zone around the Park to ensure complete coverage and adequate point densities at survey edges. Final results averaged 5.73 laser first return points/m2 over forested and high-elevation terrain, with a vertical accuracy of 3.7 cm on bare road surfaces and mean relative accuracy of 11 cm, based on comparisons between flightlines. Bare-earth topography, as developed by the contractor, is included in this release. A map of the 2007-2008 limits of glaciers and perennial snowfields was developed by digitizing 1:2,000 to 1:5,000 slope and shaded-relief images derived from the LiDAR topography. Edges of snow and exposed ice are readily seen in such images as sharp changes in surface roughness and slope. Ice mantled by moraine can be distinguished by the moraine's distinctly high roughness due to ice motion and melting, local exposures of smooth ice, and commonly by the presence of crevasses and shear boundaries. A map of the 1970 limits of ice and perennial snow was also developed by digitizing the snow and ice perimeters as depicted on the hydrologic separates used to produce the 1:24,000 topographic maps of the Mount Rainier region. These maps, produced in 1971, were derived from September 1970 aerial photographs. Boundaries between adjacent glacier systems were estimated and mapped from drainage divides, including partly emergent rock ridges, lines of diverging slope, and medial moraines. This data release contains the bare-earth LiDAR data as an ESRI grid file (DS549-Rainier_LiDAR.zip), the glacial limits derived from the USGS 1970 aerial photographs of the

    As part of HST Cy19 program 12513, we have obtained WFC3 UVIS and IR camera data of five new fields in the face-on spiral M83 which, combined with two existing fields obtained in 2009 and 2010, nearly cover the entire bright disk and spiral arms. Broadband U, B, V, I, and H will permit us to characterize the ages of 100’s of star clusters as well as the general stellar disk populations as a function of spatial position. The broadband data can also be scaled and subtracted from our narrowband Ha, [S II], [O III] and [Fe II] 1.64 micron images to allow us to find and measure 100’s of supernova remnants, planetary nebulae, and other emission nebulae. Comparison of these data with each other and with deep (729 ks) Chandra data and new radio surveys with JVLA and ATCA will allow us to search for and characterize optical counterparts to many of the X-ray sources, including especially supernova remnants and X-ray binaries, and estimate the ages of the underlying host stellar populations. We will provide an overview of this rich data set and show initial results from these comparisons. This work is supported by STScI grant HST-GO-12513.01-A to the Johns Hopkins University.

    The present survey was intended to enhance accuracy of analysis and interpretation of the geological structures in the northern and north-western parts of this area, and the status of coal seam existence. The survey used the most part of the earthquake exploration data obtained in fiscal 1988, and parts of the earthquake exploration data obtained in fiscal 1983 and fiscal 1985 in the vicinities thereof, and incorporated a new treatment method to perform re-analysis. The quaternary deposit seam has thickness of 80 to 610 m, and the Palaeogene deposit seam has thickness of 600 to 1600 m as a whole. The structure of the foundation bed is nearly parallel with the structure of the top of a coal seam in the Palaeogene deposit seam, having a distance of 300 m between the seams. The surveys combining the test drillings having been done to date and the physical exploration estimates that the coal seam groups are distributed over the entire area of Ariake Sea. Possibility has heightened, that the coal seam groups may spread over the land area. The collapsed fault passing east-west the northern most area of the Ariake Sea and having drop of 200 to 300 m forms the northern boundary of the Miike coal field. However, the coal seam groups are estimated to spread north of the coal field as a sedimentary basin, and continue to the northern side of the fault. (NEDO)

    For the purpose of grasping fracture groups forming geothermal reservoirs with accuracy, the development of the fracture type reservoir exploration method has advanced the technical development of exploration methods of seismic wave use, electromagnetic induction use, and micro-earthquake use. This paper summarized main results of the development and problems to be solved in the future. In the development of the seismic wave use exploration method, the high accuracy reflection method using seismic wave, VSP and seismic tomography were adopted to the geothermal field, and technology effective for the exploration of fracture type reservoirs was developed. In the development of the electromagnetic induction use exploration method, the array CSMT method which can measure multiple stations along the traverse line at the same time was developed with the aim of grasping effectively and accurately fracture groups forming geothermal reservoirs as changes of resistivity in the shallow-deep underground. In the fracture group forming geothermal reservoirs, micro-earthquakes are generated by movement of thermal water and pressure variations. In the development of the micro-earthquake use exploration method, developed was the micro-earthquake data processing and analysis system (MEPAS). 179 refs., 117 figs., 28 tabs.

The authors don't and can't know what conversations we had, what documents we reviewed, and what protections we put in place in each televised scene. Finally, we hope to correct several misleading examples cited by the authors as well as their offhand mischaracterization of our program as a "reality" show.

  17. Counting children at risk: exploring a method to estimate the number of children exposed to parental mental illness using adult health survey data.

    Children exposed to parental psychiatric disorders have an increased risk of several psychiatric disorders, impaired development, behavioural problems, injuries, physical illness and mortality. Even though this high-risk group has been shown to benefit from health promotion and preventive interventions, estimates of the size of the population at risk are not available. Estimating the number of exposed children using adult survey data will likely generate valuable information for health policy, planning, and advocacy. In this paper, the authors present a method to indirectly estimate the size of this population using secondary data. A Canadian adult health survey and the Census were combined to estimate the prevalence of exposure of children less than 12 years to parental and non-parental psychiatric disorders. A method to combine census and survey data is presented and tested under varying degrees of data availability. Results are compared to the actual number of children exposed to parental psychiatric disorders and discussed. The most accurate estimates were obtained when the most complete survey was combined with relatively detailed census information. Incomplete survey simulations produced substantial underestimates of the prevalence of exposure even when combined with detailed census information.

    In the second half of the 19th century, Jean-Martin Charcot (1825-1893) became famous for the quality of his teaching and his innovative neurological discoveries, bringing many French and foreign students to Paris. A hunger for recognition, together with progressive and anticlerical ideals, led Charcot to invite writers, journalists, and politicians to his lessons, during which he presented the results of his work on hysteria. These events became public performances, for which physicians and patients were transformed into actors. Major newspapers ran accounts of these consultations, more like theatrical shows in some respects. The resultant enthusiasm prompted other physicians in Paris and throughout France to try and imitate them.

    its high spatial and spectral resolution, it was possible to zoom into the very heart of this very massive star. In this innermost region, the observations are dominated by the extremely dense stellar wind that totally obscures the underlying central star. The AMBER observations show that this dense stellar wind is not spherically symmetric, but exhibits a clearly elongated structure. Overall, the AMBER observations confirm that the extremely high mass loss of Eta Carinae's massive central star is non-spherical and much stronger along the poles than in the equatorial plane. This is in agreement with theoretical models that predict such an enhanced polar mass-loss in the case of rapidly rotating stars. ESO PR Photo 06c/07 ESO PR Photo 06c/07 RS Ophiuchi in Outburst Several papers from this special feature focus on the later stages in a star's life. One looks at the binary system Gamma 2 Velorum, which contains the closest example of a star known as a Wolf-Rayet. A single AMBER observation allowed the astronomers to separate the spectra of the two components, offering new insights in the modeling of Wolf-Rayet stars, but made it also possible to measure the separation between the two stars. This led to a new determination of the distance of the system, showing that previous estimates were incorrect. The observations also revealed information on the region where the winds from the two stars collide. The famous binary system RS Ophiuchi, an example of a recurrent nova, was observed just 5 days after it was discovered to be in outburst on 12 February 2006, an event that has been expected for 21 years. AMBER was able to detect the extension of the expanding nova emission. These observations show a complex geometry and kinematics, far from the simple interpretation of a spherical fireball in extension. AMBER has detected a high velocity jet probably perpendicular to the orbital plane of the binary system, and allowed a precise and careful study of the wind and the shockwave

    International audience; Exploring for underground resources using land-based electromagnetic methods can be very challenging due to the presence of strong human-generated and " geological " noise. In such context, some passive EM techniques like the Magneto-Telluric method may not be applicable at all and a dedicated toolbox of EM techniques capable of dealing with these issues is required. We focus here on the challenges encountered while exploring for geothermal resources in volcanic island...

    Full Text Available Abstract Background Since Fuchs' report in 1999, the reported protective effect of dietary fiber from colorectal carcinogenesis has led many researchers to question its real benefit. The aim of this study is to evaluate the association between diet, especially dietary fiber and fat and colorectal cancer in Japan. Methods A multiple regression analysis (using the stepwise variable selection method was performed using the standardized mortality ratios (SMRs of colon and rectal cancer in 23 Japanese prefectures as objective variables and dietary fiber, nutrients and food groups as explanatory variables. Results As for colon cancer, the standardized partial correlation coefficients were positively significant for fat (1,13, P = 0.000, seaweeds (0.41, P = 0.026 and beans (0.45, P = 0.017 and were negatively significant for vitamin A (-0.63, P = 0.003, vitamin C (-0.42, P = 0.019 and yellow-green vegetables (-0.37, P = 0.046. For rectal cancer, the standardized partial correlation coefficient in fat (0.60, P = 0.002 was positively significant. Dietary fiber was not found to have a significant relationship with either colon or rectal cancers. Conclusions This study failed to show any protective effect of dietary fiber in subjects with a low fat intake (Japanese in this analysis, which supports Fuchs' findings in subjects with a high fat intake (US Americans.

    The objective of this study was to evaluate the general practitioners' (GPs') knowledge and perceptions towards generic medicines in a northern state of Malaysia. A postal cross-sectional survey involving registered GPs in Penang, Malaysia was undertaken. A 23-item questionnaire was developed, validated and administered on the GPs. Eighty-seven GPs responded to the survey (response rate 26.8%). The majority of the respondents (85.1%) claimed that they actively prescribed generic medicines in their practice. On the other hand, only 4.6% of the respondents correctly identified the Malaysia's National Pharmaceutical Control Bureau's bioequivalence standard for generic products. There were misconceptions among the respondents about the concepts of "bioequivalence", "efficacy", "safety", and "manufacturing standards" of generic medicines. GPs in this survey believed that a standard guideline on brand substitution process, collaboration with pharmacists, patient education and information on safety and efficacy of generic medicines were necessary to ensure quality use of generics. Furthermore, advertisements and product bonuses offered by pharmaceutical companies, patient's socio-economic factors as well as credibility of manufacturers were factors reported to influence their choice of medicine. Although it appeared that GPs have largely accepted the use of generic medicines, they still have concerns regarding the reliability and quality of such products. GPs need to be educated and reassured about generic products approval system in Malaysia concerning bioequivalence, quality, and safety. The current findings have important implications in establishing generic medicines policy in Malaysia. Copyright (c) 2009 Elsevier Ireland Ltd. All rights reserved.

    Aims: The three-point correlation function (3PCF) is a powerful probe to investigate the clustering of matter in the Universe in a complementary way with respect to lower-order statistics, providing additional information with respect to the two-point correlation function and allowing us to shed light on biasing, non-linear processes, and deviations from Gaussian statistics. In this paper, we analyse the first data release of the VIMOS Public Extragalactic Redshift Survey (VIPERS), determining the dependence of the three-point correlation function on luminosity and stellar mass at z = [ 0.5,1.1 ]. Methods: We exploit the VIPERS Public Data Release 1, consisting of more than 50 000 galaxies with B-band magnitudes in the range - 21.6 ≲ MB - 5log (h) ≲ - 19.9 and stellar masses in the range 9.8 ≲ log (M⋆ [ h-2M⊙ ] ) ≲ 10.7. We measure both the connected 3PCF and the reduced 3PCF in redshift space, probing different configurations and scales, in the range 2.5 explored. These trends, already observed at low redshifts, are confirmed for the first time to be still valid up to z = 1.1, providing support to the hierarchical scenario for which massive and bright systems are expected to be more clustered. The possibility of using the measured 3PCF to provide independent constraints on the linear galaxy bias b has also been explored, showing promising results in agreement with other probes.

    During the Bone and Joint Decade 2000-2010, national and international rheumatological societies campaign for improvements of undergraduate training in the field of musculoskeletal diseases. In 2002, the Committee for Undergraduate Training of the German Society for Rheumatology (DGRh) performed a survey in order to estimate the extent of rheumatological undergraduate training at German universities. A questionnaire was sent to all university hospitals for internal medicine and for orthopaedics. The items of the survey covered the qualification of the teachers, the number and the time frame of lessons and courses, as well as the items of the curriculum in rheumatology. With 95% of the universities responding, a broad variation of the quality of rheumatological training became obvious, ranging from the absence of competent teaching to a comprehensive curriculum covering theory and practical training. Only a minority of universities fulfilled the recommendations of the DGRh for undergraduate education. The most substantial deficits are found in practical training, caused by insufficiently small numbers of patients seen by the medical students, and by the short duration of the practical courses. The insights described here should lead to the adaptation of the level of education in the field of rheumatology to the demands of a society with growing musculoskeletal problems.

    There is a growing literature on an overall direct relationship between health and social position in developed countries. The relationship, however, is less well documented in developing countries where social hierarchies are changing more rapidly, demographic and health transitions are less advanced, and this topic has received less attention from researchers than in some developed countries. This paper presents an empirical investigation of the relationship between social stratification and social development and population health using data on over 6000 adults from the National Health Survey of Pakistan, a nationally representative health examination survey of people in that country. We analyze four indicators of poor nutrition in adults from this data set. The findings reveal complex relationships among social development, social stratification and the consequences for the health of the people of Pakistan. Underweight is related to economic status, anemia to education and social development, and both severe dental caries and a monotonous diet are related to both development and economic status which interact with each other. These results suggest that continued conceptual refinement and the development of standardized measures of stratification and development would contribute to building cross-nationally comparable data sets addressing issues of the relationship among health and economic development and health transitions.

    2014-01-01

    Several claims have been made that we are located in a locally underdense region of the Universe based on observations of supernovae and galaxy density distributions. Two recent studies of K-band galaxy surveys have provided new support for a local underdensity in the galaxy distribution out to distances of 200 - 300 Mpc. If confirmed, such large local underdensities would have important implications on the interpretation of local measurements of cosmological parameters. Galaxy clusters have been shown to be ideal probes to trace the large-scale structure of the Universe. In this paper we study the local density distribution in the southern sky with the X-ray detected galaxy clusters from the REFLEX II cluster survey. From the normalized comoving number density of clusters we find an average underdensity of ~30 - 40% in the redshift range out to z ~0.04 (~170 Mpc) in the southern extragalactic sky with a significance larger than 3.4sigma. On larger scales from 300 Mpc to over 1 Gpc the density distribution ap...

    This is a joint summary of the reports from the three Astrophysics Program Analysis Groups (PAGs) in response to the "Planning for the 2020 Decadal Survey" charge given by the Astrophysics Division Director Paul Hertz. This joint executive summary contains points of consensus across all three PAGs. Additional findings specific to the individual PAGs are reported separately in the individual reports. The PAGs concur that all four large mission concepts identified in the white paper as candidates for maturation prior to the 2020 Decadal Survey should be studied in detail. These include the Far-IR Surveyor, the Habitable-Exoplanet Imaging Mission, the UV/Optical/IR Surveyor, and the X-ray Surveyor. This finding is predicated upon assumptions outlined in the white paper and subsequent charge, namely that 1) major development of future large flagship missions under consideration are to follow the implementation phases of JWST and WFIRST; 2) NASA will partner with the European Space Agency on its L3 Gravitational W...

  14. Cross-linked survey analysis is an approach for separating cause and effect in survey research.

    2015-01-01

    We developed a new research approach, called cross-linked survey analysis, to explore how an acute exposure might lead to changes in survey responses. The goal was to identify associations between exposures and outcomes while reducing some ambiguities related to interpreting cause and effect in survey responses from a population-based community questionnaire. Cross-linked survey analysis differs from a cross-sectional, longitudinal, and panel survey analysis by individualizing the timeline to the unique history of each respondent. Cross-linked survey analysis, unlike a repeated-measures self-matching design, does not track changes in a repeated survey question given to the same respondent at multiple time points. Pilot data from three analyses (n = 1,177 respondents) illustrate how a cross-linked survey analysis can control for population shifts, temporal trends, and reverse causality. Accompanying graphs provide an intuitive display to readers, summarize results, and show differences in response distributions. Population-based individual-level linkages also reduce selection bias and increase statistical power compared with a single-center cross-sectional survey. Cross-linked survey analysis has limitations related to unmeasured confounding, pragmatics, survivor bias, statistical models, and the underlying artifacts in survey responses. We suggest that a cross-linked survey analysis may help in epidemiology science using survey data. Copyright © 2015 Elsevier Inc. All rights reserved.

    We describe first results of a spectroscopic probe of selected fields from the Grid Giant Star Survey. Multifiber spectroscopy of several hundred stars in a strip of eleven fields along delta approximately -17^{circ}, in the range 12 <~ alpha <~ 17 hours, reveals a group of 8 giants that have kinematical characteristics differing from the main field population, but that as a group maintain coherent, smoothly varying distances and radial velocities with position across the fields. Moreover, these stars have roughly the same abundance, according to their MgH+Mgb absorption line strengths. Photometric parallaxes place these stars in a semi-loop structure, arcing in a contiguous distribution between 5.7 and 7.9 kpc from the Galactic center. The spatial, kinematical, and abundance coherence of these stars suggests that they are part of a diffuse stream of tidal debris, and one roughly consistent with a wrapped, leading tidal arm of the Sagittarius dwarf spheroidal galaxy.

    Routine colorectal screening, decreases in incidence, and advances in treatment have lowered colorectal cancer mortality rates over the past three decades. Nevertheless, it remains the second most common cause of cancer death amongst men and women combined in U.S. Most cases of colon cancer are diagnosed at a late stage leading to poor survival outcomes for patients. After extensive research of publically available data, it would appear that the state of Connecticut does not have available state-wide data on patient wait times for routine colonoscopy screening. Furthermore, there are no publicly available, or Connecticut-specific, reports on Medicaid participation rates for colorectal screening amongst gastroenterologists (GI) in Connecticut. In 2012, the American Cancer Society report on Colorectal Cancer Screening Rates confirmed barriers to health-care access and disparities in health outcomes and survival rates for colon cancer patients based on race, ethnicity, and low socioeconomic status. Given this information, one could conjecture that low Medicaid participation rates among GIs could potentially have a more severe impact on health-care access and outcomes for underserved populations. At present, funding and human resources are being employed across the state of Connecticut to address bottlenecks in colorectal cancer screening. More specifically, patient navigation and outreach programs are emerging and expanding to address the gaps in services for hard-to-reach populations and the medically underserved. Low Medicaid participation rates and increased wait times for colonoscopy screening may impair the efficacy of colorectal cancer patient navigation and outreach efforts and potentially funding for future interventions. In this study, we report the results of our secret-shopper telephone survey comprising of 93 group and independent gastroenterologist (GI) practices in different counties of Connecticut.

    Researches are conducted on innovative mineral resources exploration technologies which use seismic waves or scattered electromagnetic waves to grasp the 3-dimensional structure in the ground. In fiscal 1998, a concrete research and development program is formulated, under which the seismic method and electromagnetic method will deal with an approximately 1km{sup 2}-large area of metalliferous deposit seated approximately 500m deep. In addition, researches are conducted overseas on the trend of related technologies. At an NMR (nuclear magnetic resonance) workshop held at the Society of Exploration Geophysicist, U.S., application of the NMR method to water is suggested. At a European Geophysical Society of environmental research and civil engineering event, useful knowledge is acquired about a 4-dimensional sounding (monitoring) technique in which a time axis is added to the 3-dimensional sounding technique and a high-resolution high-efficiency sounding system for probing shallow layers. During visits at Australian institutes concerned with the electromagnetic sounding technology, the trend of probing technologies especially those using the superconducting quantum interface device (SQUID) is gasped.

    Because diabetes is associated with increased colorectal cancer (CRC) risk, it is important that people with diabetes receive CRC screenings according to guidelines. In addition, many diabetes self-care recommendations are associated with a reduced risk of CRC. This study aims to identify potential opportunities for enhancing CRC prevention within the context of diabetes management. Using data from 1,730 adults with diabetes aged 50-75 years who responded to the 2010 National Health Interview Survey, we calculated population estimates of behaviors consistent with US Preventive Services Task Force guidelines for CRC screening and American Diabetes Association recommendations for diabetes care. We examined bivariate associations between CRC screening and selected diabetes self-care behaviors associated with CRC risk. Results were stratified by demographic characteristics. Thirty-nine percent of adults with diagnosed diabetes were not up-to-date with CRC screenings. Sixteen percent smoked and 2 % exceeded alcohol intake recommendations. Among those capable of exercise, 69 and 90 % did not meet aerobic exercise and resistance training recommendations, respectively. CRC screening was generally not associated with diabetes self-care behaviors. Among some demographic groups, CRC screening was associated with adequate aerobic activity, not smoking, and being overweight or obese. Many adults with diabetes do not follow guidelines for CRC screening or recommendations for diabetes care that may also reduce CRC risk. Thus, opportunities may exist to jointly promote CRC screening and prevention and diabetes self-management among adults with diabetes.

    Given the importance of reflective practice within clinical psychology and a lack of empirical research, this study aimed to investigate the personal and professional impact of reflective practice groups (RPGs) for former trainees. This study followed an analytic survey design utilizing a convenience sample of qualified clinical psychologists from a UK training programme. A RPG questionnaire (RPGQ) was developed for the purposes of the study. Following initial pilot work, 297 qualified psychologists were invited to complete the RPGQ. One hundred and twenty-four psychologists (42%) completed the RPGQ. Factor analysis yielded two underlying constructs labelled 'value' and 'distress'. The RPGQ demonstrated significant internal and test-retest reliability. The majority rated the RPGs as valuable for personal and professional development and learning about group processes. Just under half however reported distress as a result of the groups. Whilst some trainees, who reported distress, were able to view the challenges positively, one-sixth were not. Potency of facilitation and group size significantly predicted levels of perceived value and distress. In view of the ethical issues raised by compulsory RPGs, recommendations were made to keep group sizes within an average of 10-13, utilize facilitators with sufficient training in group processes and ensure additional methods of reflective practice development are available. Further suggestions and recommendations for future research in relation to coping and personal learning style were also made.  © 2009 John Wiley & Sons, Ltd.

    This paper provides a short introduction to the topic of citizen science (CS) identifying the shift from the knowledge deficit model to more inclusive, participatory science. It acknowledges the benefits of new technology and the opportunities it brings for mass participation and data manipulation. It focuses on the increase in interest in CS in recent years and draws on experience gained from the Open Air Laboratories (OPAL) programme launched in England in 2007. The drivers and objectives for OPAL are presented together with background information on the partnership, methods and scales. The approaches used by researchers ranged from direct public participation in mass data collection through field surveys to research with minimal public engagement. The supporting services focused on education, particularly to support participants new to science, a media strategy and data services. Examples from OPAL are used to illustrate the different approaches to the design and delivery of CS that have emerged over recent years and the breadth of opportunities for public participation the current landscape provides. Qualitative and quantitative data from OPAL are used as evidence of the impact of CS. While OPAL was conceived ahead of the more recent formalisation of approaches to the design, delivery and analysis of CS projects and their impact, it nevertheless provides a range of examples against which to assess the various benefits and challenges emerging in this fast developing field.

    Full Text Available Objective: Care for people with dementia is considered a multi-professional challenge that requires a collaborative approach between health professionals and non-health professionals. Didactic strategies to ensure the same qualifications across these occupational groups are lacking. This article presents the joint learning of selected properties and promotive and obstructive conditions, using the example of a multi-professional Master's programme. It subsequently draws conclusions for didactic concepts.Methodology: The perceptions of 12 teachers on this Master's programme, all representing different professions, were determined by using a qualitative exploratory survey on the three stated dimensions. With the aid of a summarising content analysis, their statements were condensed and abstracted so as to deduce appropriate requirements for methodical and didactic learning scenarios.Results: In view of the fact that the students have very varied previous knowledge, the main challenge is finding a balance between expertise and tediousness. Establishing essential and common expertise, as well as sensitivity for different perspectives, is made particularly difficult by the fact that health and non-health professions differ greatly in terms of methods and approaches. For a successful outcome, the content focal points and didactic and methodical concepts for a learning group need to take into account the composition of that specific group. Recourse to didactic standard concepts is only possible to a limited extent. Conclusions: The aim of joint teaching and learning of health and non-health professionals is to enhance the understanding of a profession: This is done by making individuals aware of their role in the chain of care, so they can recognise and organise the mutual conditionality of their own and external professional contributions.

    Children's independent everyday mobility can be hindered by fears experienced in their neighborhood. The aim of this study is to assess the prevalence and determinants of such fears among boys and girls in early adolescence, a period when individual freedom is expected to be on the increase. A sample of 7th grade students (age-13 years) in Stockholm County, Sweden, during 2005/06 answered a survey in class (n = 1,008). The relation that gender, housing, family characteristics, individual and peer negative experiences in the neighborhood, parental licensing, and length of stay in the neighborhood have with fear disclosure was assessed through multivariate logistic regression. A total of 60% of the girls and 40% of the boys reported experiencing fears in their neighborhood. Gender differences were significant for all of the most common fears, in particular darkness. When respondents or their friends had been chased, hit, or had something taken from them in their neighborhood, they were more likely to report fear (OR girls 2.3; 95% CI 1.6-4.5; boys 2.8; 95% CI 1.9-4.2). For girls, having one or more parents born outside Sweden was associated with fear. Boys nearly three times more often reported fear if (a) they thought their parents were negative toward adolescent independent mobility in the evening, or (b) they had lived longer than one year in their area. Many young adolescents admitted to experiencing fear in their neighborhood. Fears were more common among girls, and the types and determinants of fear seem to be gender specific.

    This paper presents an affirmative conclusion on the effectiveness of a Fingerprint method as a method to explore geothermal sources based on results of the survey conducted in the Sumikawa Area in Akita Prefecture. The soil gas samples from the area are classified into clusters of three kinds according to patterns in the mass spectra, and four types according to characteristics of the highly divergent components. It is shown that a distribution chart of the samples belonging to each type classified in the survey area presents a distribution that expresses well significantly the degree of activeness in geothermal activities Also shown is that the areas in which the samples of each type exist can be distinguished without a duplication a chart plotting the relationship between a total gas divergent amount'' and an average gas mass number'' by samples (a gas characteristics identifying chart). It is further indicated that the type classification according to highly divergent components and the cluster classification based on the mass spectra patterns result in a conclusion that the classifications have similarity in their descriptions. 17 refs., 11 figs., 4 tabs.

    Surveys are a valuable research tool for studying the knowledge, attitudes, and behavior of a study population. This article explores quantitative analyses of written questionnaires as instruments for survey research. Obtaining accurate and precise information from a survey requires minimizing the possibility of bias from inappropriate sampling or a flawed survey instrument, and this article describes strategies to minimize sampling bias by increasing response rates, comparing responders to nonresponders, and identifying the appropriate sampling population. It is crucial that the survey instrument be valid, meaning that it actually measures what the investigator intends it to measure. In developing a valid survey instrument, it can be useful to adapt survey instruments that were developed by other researchers and to conduct extensive pilot-testing of your survey instrument.

  12. A Classification Scheme for Young Stellar Objects Using the WIDE-FIELD INFRARED SURVEY EXPLORER ALLWISE Catalog: Revealing Low-Density Star Formation in the Outer Galaxy

    We present an assessment of the performance of WISE and the AllWISE data release in a section of the Galactic Plane. We lay out an approach to increasing the reliability of point source photometry extracted from the AllWISE catalog in Galactic Plane regions using parameters provided in the catalog. We use the resulting catalog to construct a new, revised young star detection and classification scheme combining WISE and 2MASS near and mid-infrared colors and magnitudes and test it in a section of the Outer Milky Way. The clustering properties of the candidate Class I and II stars using a nearest neighbor density calculation and the two-point correlation function suggest that the majority of stars do form in massive star forming regions, and any isolated mode of star formation is at most a small fraction of the total star forming output of the Galaxy. We also show that the isolated component may be very small and could represent the tail end of a single mechanism of star formation in line with models of molecular cloud collapse with supersonic turbulence and not a separate mode all to itself.

    In recent years, lifestyle products have emerged to help improve people's physical and mental performance. The Internet plays a major role in the spread of these products. However, the literature has reported issues regarding the authenticity of medicines purchased from the Internet and the impact of counterfeit medicines on public health. Little or no data are available on the authenticity of lifestyle products and actual toxicity associated with their use and misuse. Our aim was to investigate consumer and patient attitudes toward the purchase of lifestyle products from the Internet, their knowledge of product authenticity and toxicity, and their experiences with counterfeit lifestyle products. A Web-based study was performed between May 2014 and May 2015. Uniform collection of data was performed through an anonymous online questionnaire. Participants were invited worldwide via email, social media, or personal communication to complete the online questionnaire. A total of 320 participants completed the questionnaire. The results of the questionnaire showed that 208 (65.0%) participants purchased lifestyle products from the Internet mainly due to convenience and reduced cost. More than half (55.6%, 178/320) of participants purchased cosmetic products, whereas only a minority purchased medicinal products. Yet, 62.8% (201/320) of participants were aware of the presence of counterfeit lifestyle products from the Internet, and 11.9% (38/320) experienced counterfeit products. In only 0.9% (3/320) of those cases were counterfeit lifestyle products reported to authorities. Moreover, 7.2% (23/320) of the participants experienced adverse effects due to counterfeit lifestyle products. In summary, patients experienced counterfeit lifestyle products that resulted in adverse effects on their health. Although certain adverse effects were reported in this study, counterfeit products were underreported to authorities. Further public awareness campaigns and patient education are

  17. A matter of perception: exploring the role of income satisfaction in the income-mortality relationship in German survey data 1995-2010.

    Individual- and community-level income has been shown to be linked to social inequalities in health and mortality. On the individual level, social comparisons and relative deprivation resulting from them have been identified as relevant mechanisms involved in the relationship between income and health, but it is mainly income-based measures of relative deprivation that have been considered in previous studies. Using income satisfaction, this study employs a perception-based indicator of relative deprivation. The study, covering the period between 1995 and 2010, utilized the German Socio-Economic Panel. The follow-up included 11,056 men and 11,512 women at employment age 25-64. Discrete-time survival analysis with Cox regression was performed to estimate the effects of relative income position and income satisfaction on all-cause mortality. The univariate analysis revealed an income gradient on mortality and further showed a strong association between income satisfaction and survival. After education and employment status were adjusted for, the effect of discontent with income on mortality was still present in the female sample, whereas in the male sample only the income gradient prevailed. When self-rated health was controlled for, the hazard ratios of income satisfaction attenuated and turned non-significant for both men and women while the effects of income position remained stable. In conclusion, the findings suggest that income satisfaction and income position measure different aspects of income inequality and complement one another. Income satisfaction appeared to be a possible contributing component to the causal pathway between income and mortality.

    In our previous study (Wang et al., 2012), we analyzed scientists' working timetable of 3 countries, using realtime downloading data of scientific literatures. In this paper, we make a through analysis about global scientists' working habits. Top 30 countries/territories from Europe, Asia, Australia, North America, Latin America and Africa are selected as representatives and analyzed in detail. Regional differences for scientists' working habits exists in different countries. Besides different working cultures, social factors could affect scientists' research activities and working patterns. Nevertheless, a common conclusion is that scientists today are often working overtime. Although scientists may feel engaged and fulfilled about their hard working, working too much still warns us to reconsider the work - life balance.

  14. Preliminary studies for geothermal exploration in Hawaii, 1973--1975

    1977-12-01

    The first volume of the series on geothermal exploration in Hawaii is a compilation of information and data relevant to geothermal resources, which are available prior to the commencement of the exploration program. A narrative account of the exploration program puts into perspective the various stages of the exploration program from 1973 to 1975. The value of this narrative account lies in that it shows how the conclusion was reached to concentrate the exploration program on the east rift of Kilauea volcano as that rift zone showed the most promise of all the volcanic centers and rift zones. The narrative ends at the selection of a drilling site. The geology and hydrology of the east rift was summarized to include data existing before the exploration program and some of the early results of the field surveys. A literature survey of Kilauea volcano attempted to cover the information available on the volcano. A literature survey of the geothermal potential of the volcanoes on the island of Oahu has already been published elsewhere. A short summary and reference is included in the volume.

    The 1990s heralded a new form of museum exhibition: "The People's Show." A light-hearted celebration of popular culture, the concept has had phenomenal success throughout the United Kingdom. Beneath the humour, however, are more complex and radical agendas relating to cultural rights. The paper explores the issues associated with the rise and possible wane of this museum-based popular cultural phenomenon.

    As part of a larger search of Wide-field Infrared Survey Explorer (WISE) data for cool brown dwarfs with effective temperatures less than 1000 K, we present the discovery of three new cool brown dwarfs with spectral types later than T7. Using low-resolution, near-infrared spectra obtained with the NASA Infrared Telescope Facility and the Hubble Space Telescope, we derive spectral types of T9.5 for WISE J094305.98+360723.5, T8 for WISE J200050.19+362950.1, and Y0: for WISE J220905.73+271143.9. The identification of WISE J220905.73+271143.9 as a Y dwarf brings the total number of spectroscopically confirmed Y dwarfs to 17. In addition, we present an improved spectrum (i.e., higher signal-to-noise ratio) of the Y0 dwarf WISE J041022.71+150248.4 that confirms the Cushing et al. classification of Y0. Spectrophotometric distance estimates place all three new brown dwarfs at distances less than 12 pc, with WISE J200050.19+362950.1 lying at a distance of only 3.9-8.0 pc. Finally, we note that brown dwarfs like WISE J200050.19+362950.1 that lie in or near the Galactic plane offer an exciting opportunity to directly measure the mass of a brown dwarf via astrometric microlensing.

    2004-01-01

    We explore the utility of future photometric redshift imaging surveys for delineating the large-scale structure of the Universe, and assess the resulting constraints on the cosmological model. We perform two complementary types of analysis: (1) We quantify the statistical confidence and accuracy with which such surveys will be able to detect and measure characteristic features in the clustering power spectrum such as the acoustic oscillations and the turnover, in a model-independent fashion. For example, we show that a 10000 sq deg imaging survey with depth r = 22.5 and photometric redshift accuracy dz/(1+z) = 0.03 will detect the acoustic oscillations with 99.9% confidence, measuring the associated cosmological scale with 2% precision. Such a survey will also detect the turnover with 95% confidence, determining the corresponding scale with 20% accuracy. (2) By assuming a Lambda-CDM cosmology we calculate the confidence with which a non-zero baryon fraction can be deduced from such future surveys. After margi...

    1999-06-01

    Underground coal mining operations in the Western Coalfields of NSW extend into the Newnes Plateau area. The Newnes Plateau area is known for its floral diversity and distinctive topography. A quantitative flora assessment concerning rehabilitation performance of exploration sites was undertaken to refine the environmental component of the exploration process and identify practices that may assist in an improved rate of regeneration within disturbed areas. This article briefly summarises the method and key outcomes of the study, undertaken as part of an Honours Degree program. Surveys of sites showed that plant height was reduced due to vehicle traffic compacting soil, and this also led to a reduced number of plant species and a reduced number of seedlings germinating. Percentage litter cover was found to be positively correlated with the number of species on the sites and the percent plant cover of the regenerating vegetation, shallow surface ripping is recommended to relieve soil compaction. Seeds should be collected from exploration sites prior to disturbance, particularly of species like Banksia and Haken that retain their seed on the plant. Seed should then be dispersed after work has finished. 1 fig., 2 photos.

    Venus remains one of the most enigmatic bodies in our Solar System. Important questions remain regarding the origin and evolution of the atmosphere, the history of the surface and interior, and how the surface and atmosphere interact. In a broader context, understanding Venus has implications for understanding the evolution of terrestrial planets in our Solar System as well as for interpreting the growing set of observations of extra-solar planets. The Venus Exploration Analysis Group (VEXAG), established in 2005, is chartered by NASA's Planetary Science Division and reports its findings to the NASA Advisory Council. Open to all interested scientists, VEXAG regularly evaluates Venus exploration goals, scientific objectives, investigations and critical measurement requirements, including especially recommendations in the NRC Decadal Survey and the Solar System Exploration Strategic Roadmap. At the last general meeting in November 2012, VEXAG resolved to update the scientific priorities and strategies for Venus exploration. To achieve this goal, three major tasks were defined for 2013, (1) update the document prioritizing Goals, Objectives and Investigations for Venus Exploration, (2) develop a Roadmap for Venus exploration that is consistent with VEXAG priorities as well as Planetary Decadal Survey priorities, and (3) develop a white paper on technologies for Venus missions. Proposed versions of all three documents were presented at the VEXAG general meeting in November 2013. Here, we present the findings and final versions of all three documents for community comment and feedback. A follow-on Workshop on Venus Exploration Targets is also being planned for the early summer of 2014. The workshop will provide a forum for the Venus science community to discuss approaches for addressing high priority investigations. Participants will be encouraged to present their ideas for specific targets on Venus (interior, surface and atmosphere) as well as to present specific data

    2013-01-01

    This paper reports on an extension of generic airspace research to explore the amount of memorization and specialized skills required to manage sectors with specific characteristics or factors. Fifty-five retired controllers were given an electronic survey where they rated the amount of memorization or specialized skills needed for sixteen generic airspace factors. The results suggested similarities in the pattern of ratings between different areas of the US (East, Central, and West). The average of the ratings for each area also showed some differences between regions, with ratings being generally higher in the East area. All sixteen factors were rated as moderately to highly important and may be useful for future research on generic airspace, air traffic controller workload, etc.

    Mars is our neighbour planet and has always fascinated humans as it has been seen as a potential abode for life. Knowledge about Mars is huge and was constructed step by step through numerous missions. It could be difficult to describe these missions, the associated technology, the results, the questions they raise, that's why an activity is proposed, that directly interests students. Their production is presented in the poster. Step 1: The main Mars feature and the first Mars explorations using telescope are presented to students. It should be really interesting to present "Mars Canals" from Percival Lowell as it should also warn students against flawed interpretation. Moreover, this study has raised the big question about extra-terrestrial life on Mars for the first time. Using Google Mars is then a good way to show the huge knowledge we have on the planet and to introduce modern missions. Step 2: Students have to choose and describe one of the Mars mission from ESA and NASA. They should work in pairs. Web sites from ESA and NASA are available and the teacher makes sure the main missions will be studied. Step 3: Students have to collect different pieces of information about the mission - When? Which technology? What were the main results? What type of questions does it raise? They prepare an oral presentation in the form they want (role play, academic presentation, using a poster, PowerPoint). They also have to produce playing cards about the mission that could be put on a timeline. Step 4: As a conclusion, the different cards concerning different missions are mixed. Groups of students receive cards and they have to put them on a timeline as fast as possible. It is also possible to play the game "timeline".

    Full Text Available This study explored how researchers’ views about the form of students’ epistemologies influence how the researchers develop and refine surveys and how they interpret survey results. After running standard statistical analyses on 505 physics students’ responses to the Turkish version of the Maryland Physics Expectations-II survey, probing students’ epistemologies and expectations, we interpreted the results through two different theoretical lenses, the beliefs perspective and the resources perspective. We showed that the beliefs and resources frameworks provided different interpretations of the psychometric analyses, leading to different conclusions about how the survey results should be interpreted and how the survey should be improved.

    Full Text Available Implementation of evidence-based guidelines (EBGs is an effective measure for prevention of ventilator-associated pneumonia (VAP. Appropriate knowledge, attitude and adherence of healthcare workers (HCWs to EBGs are necessary factors for implementation of EBGs. This study was conducted with objective of evaluation of knowledge, attitude, and adherence of HCWs to EBGs for prevention of VAP and exploration of the barriers of their implementation in clinical practice. Totally, a total number of 45 HCWs of two pediatric cardiac surgery ICU (PCICUs participated in this quali-quantitative survey. Knowledge, attitude and adherence of participants was evaluated by a validated multiple-choice questionnaire and barriers of implementation of EBGs was extracted from participants’ answer to an open-ended question of our self-made questionnaire. Knowledge of HCWs was poor and significantly different between nurse assistants (RAs, nurses (RNs, and physicians (MDs (respectively, 1.25±0.95, 4.53±1.73, and 5.54±2.01, P=0.001. Likewise, attit ude of HCWs is not positive and significantly different between NAs, RNs, and MDs (respectively, 32.96±2.42, 34.00±2.44, 36.81±4.35, P=0.003. The adherence of HCWs is not good and different between RAs, RNs, and MDs (respectively, 11.50±1.00, 13.13±1.83, and 17.18±6.06, P= 0.17. The Barriers of implementation of EBGs was categorized into four category of individual, organizational, social, and educational factors. Unsatisfying status of knowledge, attitude, and adherence of HCWs is a challenging concern of health-care system, especially in PICUs. In addition to these well-known factors, poor implementation of EBGs is related to many other barriers which should recognized and taken into consideration for designation of infection controlling programs.

  7. Reality show: um paradoxo nietzschiano

    O fenômeno dos reality shows - e a subseqüente relação entre imagem e verdade - assenta-se sobre uma série de paradoxos. Tais paradoxos podem ser compreendidos à luz do pensamento do filósofo alemão Friedrich Nietzsche, que, através dos usos de formulações paradoxais, concebia a realidade como um mundo de pura aparência e a verdade como um acréscimo ficcional, como um efeito. A ficção é então tomada, na filosofia de Nietzsche, não em seu aspecto falsificante e desrealizador - como sempre pleiteou nossa tradição metafísica -, mas como condição necessária para que certa espécie de invenção possa operar como verdade. Sendo assim, a própria expressão reality show, através de sua formulação paradoxal, engendra explicitamente um mundo de pura aparência, em que a verdade, a parte reality da proposição, é da ordem do suplemento, daquilo que se acrescenta ficcionalmente - como um adjetivo - a show. O ornamento, nesse caso, passa a ocupar o lugar central, apontando para o efeito produzido: o efeito-de-verdade. Seguindo, então, o pensamento nietzschiano e sua atualização na contemporaneidade, investigaremos de que forma os televisivos “shows de realidade” operam paradoxalmente, em consonância com nossas paradoxais práticas culturais.

  11. Reality shows: uma abordagem psicossocial

    Directory of Open Access Journals (Sweden)

    Marília Pereira Bueno Millan

    Full Text Available Desde os primórdios da civilização, o ser humano mostra necessidade de representar cenicamente seus dramas pessoais e vicissitudes existenciais. O "reality show" é uma das versões pós-modernas da encenação da vida humana. Este artigo, por meio de uma pesquisa bibliográfica, analisa criticamente as relações existentes entre o "reality show" e aspectos psicossociais do comportamento humano. Conclui-se que tais programas televisivos são o retrato da contemporaneidade, ou seja, revelam a morte do sujeito, a fugacidade das experiências vividas, a desvalorização da história e o culto à imagem e à superficialidade. Por meio da sedução do espectador, mobilizam-se aspectos primitivos de seu psiquismo, fazendo com que ele se sinta narcisicamente poderoso e onipotente e se acredite dono do destino dos participantes do programa. Sugerem-se novos estudos que contribuam para a reflexão crítica e maior conscientização.

    This is an excerpt from the script of a 1939 play provided to the Institute of Social Medicine and Community Health by the Library of Congress Federal Theater Project Collection at George Mason University Library, Fairfax, Virginia, pages 2-1-8 thru 2-1-14. The Federal Theatre Project (FTP) was part of the New Deal program for the arts 1935-1939. Funded by the Works Progress Administration (WPA) its goal was to employ theater professionals from the relief rolls. A number of FTP plays deal with aspects of medicine and public health. Pageants, puppet shows and documentary plays celebrated progress in medical science while examining social controversies in medical services and the public health movement. "Medicine Show" sharply contrasts technological wonders with social backwardness. The play was rehearsed by the FTP but never opened because funding ended. A revised version ran on Broadway in 1940. The preceding comments are adapted from an excellent, well-illustrated review of five of these plays by Barabara Melosh: "The New Deal's Federal Theatre Project," Medical Heritage, Vol. 2, No. 1 (Jan/Feb 1986), pp. 36-47.

    We address several different Casimir experiments where theory and experiment disagree. First out is the classical Casimir force measurement between two metal half spaces; here both in the form of the torsion pendulum experiment by Lamoreaux and in the form of the Casimir pressure measurement between a gold sphere and a gold plate as performed by Decca et al.; theory predicts a large negative thermal correction, absent in the high precision experiments. The third experiment is the measurement of the Casimir force between a metal plate and a laser irradiated semiconductor membrane as performed by Chen et al.; the change in force with laser intensity is larger than predicted by theory. The fourth experiment is the measurement of the Casimir force between an atom and a wall in the form of the measurement by Obrecht et al. of the change in oscillation frequency of a 87 Rb Bose-Einstein condensate trapped to a fused silica wall; the change is smaller than predicted by theory. We show that saturation effects can exp...

    Objective To investigate a cluster of HIV infection among MSMs in a club and explore its influencing factors, so as to provide information for implementing behavior interventions. Methods The fingerprint identification system was used to eliminate repeated research objects. The respondents were surveyed by questionnaires and their behaviors were monitored. The contents of the questionnaires included social demographic, knowledge and behavior characteristics. The serologic monitoring items included serologic indices of AIDS, syphilis and hepatitis C infections. The HIY infection status among the MSM crowd and the influencing factors were analyzed by chi - square test and Logistic regression analysis. Results A total of 266 MSMs were monitored. The positive rates of anti - HIV, syphilis antibody and anti - HCV were 16.2% , 10.2% and 2.6% , respectively. The proportions of MSMs with the first sexual behavior at the age of < 15, 15~ and 20 ~ years were 5.6% , 83.1% and 11.3%, respectively. 48.5% of the MSMs had males as their first sexual partners and 51.5% had females. As to the sexual orientation, the gays, heterosexuals and bisexuals accounted for 48. 5% , 7.1% and 35.7% , respectively. And the remainder were uncertain about their sexual orientation (8.7%). The accuracy rate of the answers to AIDS/STD knowledge was 67.3% . The MSMs who had <20, 20- and 30- sexual partners in half a year accounted for 61.3% , 12.0% and 26.7%, respectively. In the respect of the sexual behavior, the anal sex, anal sex & oral sex, anal sex & vaginal sex, and anal sex & oral sex & vaginal sex accounted for 35.0% , 17. 7% , 34. 2% and 13.1% , respectively. The self awareness rate of the risk to contract HIV infection was 57.5% , while only 22.9% of them used condoms each time when they had high- risk sexual behaviors. As to the frequency of going to' the club, 71. 1% went to the club more than once a month, and 28. 9% went less than

  16. Extragalactic HI Surveys

    CERN Document Server

    Giovanelli, Riccardo

    2015-01-01

    We review the results of HI line surveys of extragalactic sources in the local Universe. In the last two decades major efforts have been made in establishing on firm statistical grounds the properties of the HI source population, the two most prominent being the HI Parkes All Sky Survey (HIPASS) and the Arecibo Legacy Fast ALFA survey (ALFALFA). We review the choices of technical parameters in the design and optimization of spectro-photometric "blind" HI surveys, which for the first time produced extensive HI-selected data sets. Particular attention is given to the relationship between optical and HI populations, the differences in their clustering properties and the importance of HI-selected samples in contributing to the understanding of apparent conflicts between observation and theory on the abundance of low mass halos. The last section of this paper provides an overview of currently ongoing and planned surveys which will explore the cosmic evolution of properties of the HI population.

The core of our work is a systematic enumeration algorithm that can generate all possible quadrangular meshes inside a defined boundary with an upper limit of v3-v5 pairs. The algorithm is orders of magnitude more efficient than previous work. The combination of topological enumeration and shape-space exploration demonstrates that mesh topology has a powerful influence on geometry. The Fig. 18.

    Gordon, Jeffry S; McNew, Ryan

    2008-12-01

    Institutions of higher education are now using Internet-based technology tools to conduct surveys for data collection. Research shows that the type and quality of responses one receives with online surveys are comparable with what one receives in paper-based surveys. Data collection can take place on Web-based surveys, e-mail-based surveys, and personal digital assistants/Smartphone devices. Web surveys can be subscription templates, software packages installed on one's own server, or created from scratch using Web programming development tools. All of these approaches have their advantages and disadvantages. The survey owner must make informed decisions as to the right technology to implement. The correct choice can save hours of work in sorting, organizing, and analyzing data.

    Researchers in a number of disciplines deal with large text sets requiring both text management and text analysis. Faced with a large amount of textual data collected in marketing surveys, literary investigations, historical archives and documentary data bases, these researchers require assistance with organizing, describing and comparing texts. Exploring Textual Data demonstrates how exploratory multivariate statistical methods such as correspondence analysis and cluster analysis can be used to help investigate, assimilate and evaluate textual data. The main text does not contain any strictly mathematical demonstrations, making it accessible to a large audience. This book is very user-friendly with proofs abstracted in the appendices. Full definitions of concepts, implementations of procedures and rules for reading and interpreting results are fully explored. A succession of examples is intended to allow the reader to appreciate the variety of actual and potential applications and the complementary processin...

  4. Variable selection and estimation for longitudinal survey data

    KAUST Repository

    Wang, Li

    2014-09-01

    There is wide interest in studying longitudinal surveys where sample subjects are observed successively over time. Longitudinal surveys have been used in many areas today, for example, in the health and social sciences, to explore relationships or to identify significant variables in regression settings. This paper develops a general strategy for the model selection problem in longitudinal sample surveys. A survey weighted penalized estimating equation approach is proposed to select significant variables and estimate the coefficients simultaneously. The proposed estimators are design consistent and perform as well as the oracle procedure when the correct submodel was known. The estimating function bootstrap is applied to obtain the standard errors of the estimated parameters with good accuracy. A fast and efficient variable selection algorithm is developed to identify significant variables for complex longitudinal survey data. Simulated examples are illustrated to show the usefulness of the proposed methodology under various model settings and sampling designs. © 2014 Elsevier Inc.

    Purpose A connectome is a comprehensive description of synaptic connectivity for a neural domain. Our goal was to produce a connectome data set for the inner plexiform layer of the mammalian retina. This paper describes our first retinal connectome, validates the method, and provides key initial findings. Methods We acquired and assembled a 16.5 terabyte connectome data set RC1 for the rabbit retina at ≈2 nm resolution using automated transmission electron microscope imaging, automated mosaicking, and automated volume registration. RC1 represents a column of tissue 0.25 mm in diameter, spanning the inner nuclear, inner plexiform, and ganglion cell layers. To enhance ultrastructural tracing, we included molecular markers for 4-aminobutyrate (GABA), glutamate, glycine, taurine, glutamine, and the in vivo activity marker, 1-amino-4-guanidobutane. This enabled us to distinguish GABAergic and glycinergic amacrine cells; to identify ON bipolar cells coupled to glycinergic cells; and to discriminate different kinds of bipolar, amacrine, and ganglion cells based on their molecular signatures and activity. The data set was explored and annotated with Viking, our multiuser navigation tool. Annotations were exported to additional applications to render cells, visualize network graphs, and query the database. Results Exploration of RC1 showed that the 2 nm resolution readily recapitulated well known connections and revealed several new features of retinal organization: (1) The well known AII amacrine cell pathway displayed more complexity than previously reported, with no less than 17 distinct signaling modes, including ribbon synapse inputs from OFF bipolar cells, wide-field ON cone bipolar cells and rod bipolar cells, and extensive input from cone-pathway amacrine cells. (2) The axons of most cone bipolar cells formed a distinct signal integration compartment, with ON cone bipolar cell axonal synapses targeting diverse cell types. Both ON and OFF bipolar cells receive

    In this decade, terrestrial laser scanner (TLS) is getting popular in many fields such as reconstruction, monitoring, surveying, as-built of facilities, archaeology, and topographic surveying. This is due the high speed in data collection which is about 50,000 to 1,000,000 three-dimensional (3D) points per second at high accuracy. The main advantage of 3D representation for the data is that it is more approximate to the real world. Therefore, the aim of this paper is to show the use of High-Definition Surveying (HDS), also known as 3D laser scanning for topographic survey. This research investigates the effectiveness of using terrestrial laser scanning system for topographic survey by carrying out field test in Universiti Teknologi Malaysia (UTM), Skudai, Johor. The 3D laser scanner used in this study is a Leica ScanStation C10. Data acquisition was carried out by applying the traversing method. In this study, the result for the topographic survey is under 1st class survey. At the completion of this study, a standard of procedure was proposed for topographic data acquisition using laser scanning systems. This proposed procedure serves as a guideline for users who wish to utilize laser scanning system in topographic survey fully.

    Despite the fact infectious diseases can spread readily in grade schools, few studies have explored prevention in this setting. Additionally, we lack valid tools for students to self-report knowledge, attitudes, and behaviors. As part of an ongoing study of a curriculum intervention to promote healthy behaviors, we developed and evaluated age-appropriate surveys to determine students' understanding of influenza prevention. Surveys were adapted from adolescent and adult influenza surveys and administered to students in grades 2-5 (ages 7-11) at two Rochester public schools. We assessed student understanding by analyzing percent repeatability of 20 survey questions and compared percent "don't know" (DK) responses across grades, gender, and race. Questions thought to be ambiguous after early survey administration were investigated in student focus groups, modified as appropriate, and reassessed. The response rate across all surveys was >87%. Survey questions were well understood; 16 of 20 questions demonstrated strong pre/post repeatability (>70%). Only 1 question showed an increase in DK response for higher grades (p survey questions and improved measures of understanding in the final survey administration. Grade-school students' knowledge, attitudes and behavior toward influenza prevention can be assessed using surveys. Quantitative and qualitative analysis may be used to assess participant understanding and refine survey development for pediatric survey instruments. These methods may be used to assess the repeatability and validity of surveys to assess the impact of health education interventions in young children.

    2016-11-01

    We present an analysis of surveying the inner solar system for objects that may pose some threat to Earth. Most of the analysis is based on understanding the capability provided by Sentinel, a concept for an infrared space-based telescope placed in a heliocentric orbit near the distance of Venus. From this analysis, we show that (1) the size range being targeted can affect the survey design, (2) the orbit distribution of the target sample can affect the survey design, (3) minimum observational arc length during the survey is an important metric of survey performance, and (4) surveys must consider objects as small as D=15{--}30 m to meet the goal of identifying objects that have the potential to cause damage on Earth in the next 100 yr. Sentinel will be able to find 50% of all impactors larger than 40 m in a 6.5 yr survey. The Sentinel mission concept is shown to be as effective as any survey in finding objects bigger than D = 140 m but is more effective when applied to finding smaller objects on Earth-impacting orbits. Sentinel is also more effective at finding objects of interest for human exploration that benefit from lower propulsion requirements. To explore the interaction between space and ground search programs, we also study a case where Sentinel is combined with the Large Synoptic Survey Telescope (LSST) and show the benefit of placing a space-based observatory in an orbit that reduces the overlap in search regions with a ground-based telescope. In this case, Sentinel+LSST can find more than 70% of the impactors larger than 40 m assuming a 6.5 yr lifetime for Sentinel and 10 yr for LSST.

    2010-10-01

    Space agencies such as NASA and ESA have ambitious long-term programmes that mark the beginning of a new era in space exploration where humans will land on Mars; an era requiring public support and, therefore, more consideration for public opinion. Empirical research shows that there are substantial differences in the level of understanding of space exploration among the general public. Studying audiences appears to be crucial to inform public engagement and communication strategies as well as policy debate. This paper presents the results of a survey conducted in the UK in 2008 at two science outreach events, the Royal Society Exhibition in London and the National Space Centre in Leicester, to investigate the motivations, beliefs, political preferences and attitudes towards space exploration of this audience. A sample of 744 respondents was collected. The analysis shows that the British public who come to outreach and engagement activities support space exploration but have some reservations about considering the advancement of UK space activities to be of national interest. Yet, when asked about means of exploring space, the majority agrees that space should be explored using both mankind and machines, ranking "generating new scientific knowledge and advancing human culture" as the most important reason for continuing investment in space research. Although the greater number of supporters says that more than the current government funding should be allocated to civil space activities, concerns about risk and value appear to influence this view.

    Full Text Available Quantifying soil organic carbon stocks and their dynamics accurately is crucial for better predictions of climate change feedbacks within the atmosphere-vegetation-soil system. However, the composition and environmental responses of the soil CO2 efflux (Rs are still debated and limited by field data. The objective of this study was to quantify the contribution of the various Rs components and to determine their temporal variability, environmental responses and dependence on gross primary productivity (GPP using time series analysis. In a deciduous oak forest in SE England hourly replicated Rs fluxes over 4 years were obtained using automated soil CO2 flux chambers and ecosystem CO2 exchange using eddy covariance methodology. Mesh-bag and steel collar treatments prevented root or both roots and mycorrhizal hyphal in-growth, respectively, to allow separation of heterotrophic (Rh and autotrophic (Ra soil CO2 fluxes and the Ra components, roots (Rr and mycorrhizal hyphae (Rm. Annual cumulative Rs values were very similar between years (740 ± 43 g C m−2 yr−1 with an average flux of 2.0 ± 0.3 μmol CO2 m−2 s−1, but Rs components varied. On average, annual Rr, Rm and Rh fluxes contributed 39, 18 and 43%, respectively, showing a large Ra contribution (57% comprising considerable seasonal Rm contributions. Soil temperature largely explained the daily variation of Rs (R2 = 0.81, mostly because of strong responses by Rh (R2 = 0.65 and less so for Rr (R2 = 0.41 and Rm (R2 = 0.18. However, Ra components showed strong apparent temperature responses around budburst and leaf fall but none during summer. Time series analysis revealed strong daily periodicities for Rs, whereas Rr was dominated by daily, Rm by seasonal (~150 days, and Rh by annual periodicities. Wavelet coherence analysis revealed that Rr and Rm were related to short-term (daily GPP changes, but for R the relationship with GPP was substantial over much longer (weekly to monthly periods

  18. Investigation of background acoustical effect on online surveys: A case study of a farmers' market customer survey

    Science.gov (United States)

    Tang, Xingdi

    Since the middle of 1990s, internet has become a new platform for surveys. Previous studies have discussed the visual design features of internet surveys. However, the application of acoustics as a design characteristic of online surveys has been rarely investigated. The present study aimed to fill that research gap. The purpose of the study was to assess the impact of background sound on respondents' engagement and satisfaction with online surveys. Two forms of background sound were evaluated; audio recorded in studios and audio edited with convolution reverb technique. The author recruited 80 undergraduate students for the experiment. These students were assigned to one of three groups. Each of the three groups was asked to evaluate their engagement and satisfaction with a specific online survey. The content of the online survey was the same. However, the three groups was exposed to the online survey with no background sound, with background sound recorded in studios; and with background sound edited with convolution reverb technique. The results showed no significant difference in engagement and satisfaction in the three groups of online surveys; without background sound, background sound recorded in studios, and background sound edited with convolution reverb technique. The author suggests that background sound does not contribute to online surveys in all the contexts. The industry practitioners should be careful to evaluate the survey context to decide whether the background sound should be added. Particularly, ear-piercing noise or acoustics which may link to respondents' unpleasant experience should be avoided. Moreover, although the results did not support the advantage of the revolution reverb technique in improving respondents' engagement and satisfaction, the author suggests that the potential of the revolution reverb technique in the applications of online surveys can't be totally denied, since it may be useful for some contexts which need further

    Caruso, Eugene M; Shapira, Oren; Landy, Justin F

    2017-08-01

    A major challenge for accumulating knowledge in psychology is the variation in methods and participant populations across studies in a single domain. We offer a systematic approach to addressing this challenge and implement it in the domain of money priming. In three preregistered experiments ( N = 4,649), participants were exposed to one of a number of money manipulations before completing self-report measures of money activation (Study 1); engaging in a behavioral-persistence task (Study 3); completing self-report measures of subjective wealth, self-sufficiency, and communion-agency (Studies 1-3); and completing demographic questions (Studies 1-3). Four of the five manipulations we tested activated the concept of money, but, contrary to what we expected based on the preponderance of the published literature, no manipulation consistently affected any dependent measure. Moderation by sociodemographic characteristics was sparse and inconsistent across studies. We discuss implications for theories of money priming and explain how our approach can complement recent efforts to build a reproducible, cumulative psychological science.

  4. An Explorative Approach for Inspecting Kepler Data

    CERN Document Server

    Kügler, S D; Polsterer, K L

    2015-01-01

    The Kepler survey has provided a wealth of astrophysical knowledge by continuously monitoring over 150,000 stars. The resulting database contains thousands of examples of known variability types and at least as many that cannot be classified yet. In order to reveal the knowledge hidden in the database, we introduce a new visualisation method that allows us to inspect time series exploratively. To that end, we propose dimensionality reduction on the parameters of a model capable of representing time series as fixed-length vector representation. We show that a more refined objective function can be chosen by minimising the prediction error of the data reconstruction instead of the reconstruction of the model parameters. The proposed visualisation exhibits a strong correlation between the variability behaviour of the light curves and their physical properties. As a consequence, temperature and surface gravity can, for some stars, be directly inferred from non- (or quasi-) periodic light curves.

  8. Common (misbeliefs about memory: a replication and comparison of telephone and Mechanical Turk survey methods.

    Directory of Open Access Journals (Sweden)

    Daniel J Simons

    Full Text Available Incorrect beliefs about memory have wide-ranging implications. We recently reported the results of a survey showing that a substantial proportion of the United States public held beliefs about memory that conflicted with those of memory experts. For that survey, respondents answered recorded questions using their telephone keypad. Although such robotic polling produces reliable results that accurately predicts the results of elections, it suffers from four major drawbacks: (1 telephone polling is costly, (2 typically, less than 10 percent of calls result in a completed survey, (3 calls do not reach households without a landline, and (4 calls oversample the elderly and undersample the young. Here we replicated our telephone survey using Amazon Mechanical Turk (MTurk to explore the similarities and differences in the sampled demographics as well as the pattern of results. Overall, neither survey closely approximated the demographics of the United States population, but they differed in how they deviated from the 2010 census figures. After weighting the results of each survey to conform to census demographics, though, the two approaches produced remarkably similar results: In both surveys, people averaged over 50% agreement with statements that scientific consensus shows to be false. The results of this study replicate our finding of substantial discrepancies between popular beliefs and those of experts and shows that surveys conducted on MTurk can produce a representative sample of the United States population that generates results in line with more expensive survey techniques.

    The three-point correlation function (3PCF) is a powerful probe to investigate the clustering of matter in the Universe in a complementary way with respect to lower-order statistics, providing additional information with respect to two-point correlation function and allowing to shed light on biasing, nonlinear processes and deviations from Gaussian statistics. In this paper, we analyse the first data release of the VIMOS Public Extragalactic Redshift Survey (VIPERS), determining the dependence of the three-point correlation function on luminosity and stellar mass at $z=[0.5,1.1]$. We exploit the VIPERS Public Data Release 1, consisting of more than 50000 galaxies with B-band magnitudes in the range $-21.6\\lesssim M_{\\rm B}-5\\log(h)\\lesssim-19.9$ and stellar masses in the range $9.8\\lesssim\\log(M_\\star[h^{-2}\\,M_\\odot])\\lesssim 10.7$.

    Low socioeconomic position (SEP) tends to be linked to higher use of general practitioners (GPs), while the use of health care specialists is more common in higher SEPs. Despite extensive literature in this area, previous studies have, however, only studied health care use by income or education. The aim of this study is, therefore, to examine inequalities in GP and health care specialist use by four social markers that may be linked to health care utilization (educational level, occupational status, level of financial strain and size and frequency of social networks) across 20 European countries and Israel. Logistic regression models were employed using data from the seventh round of the European Social Survey; this study focused upon people aged 25–75 years, across 21 countries. Health care utilization was measured according to self-reported use of GP or specialist care within 12 months. Analyses tested four social markers: income (financial strain), occupational status, education and social networks. We observed a cross-national tendency that countries with higher or equal probability of GP utilization by lower SEP groups had a more consistent probability of specialist use among high SEP groups. Moreover, countries with inequalities in GP use in favour of high SEP groups had comparable levels of inequalities in specialist care utilization. This was the case for three social markers (education, occupational class and social networks), while the pattern was less pronounced for income (financial strain). There are significant inequalities associated with GP and specialist health care use across Europe—with higher SEP groups more likely to use health care specialists, compared with lower SEP groups. In the context of health care specialist use, education and occupation appear to be particularly important factors.

    The objectives of the Technology Watch process are to identify emerging, high-impact technologies that augment current ExMC development efforts, and to work with academia, industry, and other government agencies to accelerate the development of medical care and research capabilities for the mitigation of potential health issues that could occur during space exploration missions. The establishment of collaborations with these entities is beneficial to technology development, assessment and/or insertion. Such collaborations also further NASA s goal to provide a safe and healthy environment for human exploration. The Tech Watch project addresses requirements and capabilities identified by knowledge and technology gaps that are derived from a discrete set of medical conditions that are most likely to occur on exploration missions. These gaps are addressed through technology readiness level assessments, market surveys, collaborations and distributed innovation opportunities. Ultimately, these gaps need to be closed with respect to exploration missions, and may be achieved through technology development projects. Information management is a key aspect to this process where Tech Watch related meetings, research articles, collaborations and partnerships are tracked by the HRP s Exploration Medical Capabilities (ExMC) Element. In 2011, ExMC will be introducing the Tech Watch external website and evidence wiki that will provide access to ExMC technology and knowledge gaps, technology needs and requirements documents.

The level of oil exploitation in the ocean that has been 200m or shallower in the past is now advancing deeper toward levels lower than 1000m. As for pilot drilling, although a 2000m-deep level is regarded as the limit beyond which progress deeper would be difficult, yet drilling into a 3000m-deep level is now being planned. Among drilling contractors, reorganization is under way through merger and acquisition. Although the total number of rigs has reduced, demand for rigs turned strong in 1996, and the number of rigs is increasing rapidly through new construction or refurbishment. As for ocean development systems, various practical applications have added to the list of available systems. 3 figs., 6 tabs.

  11. EUVE GO Survey: High Levels of User Satisfaction

    Science.gov (United States)

    Stroozas, B. A.

    2000-12-01

    This paper describes the results of a detailed customer survey of Guest Observers (GOs) for NASA's Extreme Ultraviolet Explorer (EUVE) astronomy satellite observatory. The purpose of the research survey was to (1) measure the levels of GO customer satisfaction with respect to EUVE observing services, and (2) compare the observing experiences of EUVE GOs with their experiences using other satellite observatories. This survey was conducted as a business research project -- part of the author's graduate work as an MBA candidate. A total sample of 38 respondents, from a working population of 101 "active" EUVE GOs, participated in this survey. The results, which provided a profile of the "typical" EUVE GO, showed in a statistically significant fashion that these GOs were more than satisfied with the available EUVE observing services. In fact, the sample GOs generally rated their EUVE observing experiences to be better than average as compared to their experiences as GOs on other missions. These relatively high satisfaction results are particularly pleasing to the EUVE Project which, given its significantly reduced staffing environment at U.C. Berkeley, has continued to do more with less. This paper outlines the overall survey process: the relevant background and previous research, the survey design and methodology, and the final results and their interpretation. The paper also points out some general limitations and weaknesses of the study, along with some recommended actions for the EUVE Project and for NASA in general. This work was funded by NASA/UCB Cooperative Agreement NCC5-138.

  12. Revisiting Dystopia: the Reality Show Biopolitics of "The Hunger Games"

    Directory of Open Access Journals (Sweden)

    Fani Cettl

    2015-10-01

    Full Text Available This paper explores the dystopian imaginaries of the recent popular novel trilogy The Hunger Games by Suzanne Collins and its film adaptations. Having put the narrative into a genealogy of dystopian fiction concerned with the historical nation-state totalitarianisms, I ask what is specifically contemporary about The Hunger Games. I explore this by focusing on the functioning of the reality show format in the narrative, which I link to G. Agamben’s understanding of the spectacle, as part of his wider biopolitical theories. I apply an Agambenian biopolitical reading to the narrative, seeing it as a production of bare life through the camp of the reality show arena. I suggest that The Hunger Games offer a critique of contemporary liberal democracies by calling attention to their production of underclassed and expendable life, which is imagined as an eruption of the nation-state right to kill, similarly as in Agamben’s theories.

  13. Snacking on Television: A Content Analysis of Adolescents’ Favorite Shows

    Larson, Nicole I.; Gollust, Sarah E.; Neumark-Sztainer, Dianne

    2016-01-01

    Introduction Snacking is a complex behavior that may be influenced by entertainment media. Research suggests that snacking and unhealthy foods are commonly shown in programming that targets young audiences, but shows selected for study have been limited. We conducted a content analysis on shows that were named as favorites by adolescents to characterize portrayals of snacking on popular television. Methods A diverse sample of 2,130 adolescents (mean age, 14.3 y) listed 3 favorite television shows in a 2010 school-based survey. Three episodes each of the 25 most popular shows were coded for food-related content, including healthfulness, portion size, screen time use, setting, and social context. We also analyzed the characteristics of characters involved in eating incidents, the show type, and the show rating. We used χ2 tests, binomial tests, and multilevel regression models to compare incidence of snacks versus meals, the characteristics of those involved, and snacking across show characteristics. Results Almost half of food incidents on television shows were snacks. Snacks were significantly more likely than meals to be “mostly unhealthy” (69.3% vs 22.6%, P Sitcoms and shows rated for a youth audience were significantly more likely to portray snacking than were shows for adult audiences. Conclusion Media awareness and literacy programs should include foods and snacking behaviors among the issues they address. More healthful portrayals of food and dietary intake in entertainment shows’ content would create a healthier media environment for youth. PMID:27197079

    2017-01-01

    This book dissects the hype and hubris of the Mars One venture. Every aspect of the mission design is scrutinized, from the haphazard selection process to the unproven mission architecture. A controversial project, many professional astronauts consider Mars One a reckless attempt, yet it gained popular attention. This go-to reference guide provides the reader with insights into the myriad issues arising from the project's loss of funding, loss of sponsorship, loss of TV rights. It explains what contributed to an overly optimistic assessment of Mars One's mission-specific technology, and what captivated the public and the many willing candidates despite these flaws. From the author of Survival and Sacrifice in Mars Exploration (2015) among many more books on spacefaring, this is yet another up-to-the-minute account of an emerging player in the private space market from an expert on the subject.

However, statistics from the Jamaican Ministry of Health showed that there are inaccuracies in health data collected from males using sample surveys.Objectives: The objectives of the present research are to 1 investigate the accuracy of a national sample survey, 2 explore the feasibility and quality of using a subnational sample survey to represent a national survey, 3 aid other scholars in understanding the probability of using national sample surveys and subnational sample surveys, 4 assess older men’s ­evaluation of their health status, and 5 determine whether dichotomization changes self-evaluated health status.Methods: For the current study, the data used in the analysis were originally collected from 2 different sources: 1 the Jamaica Survey of Living Conditions (JSLC and 2 Survey of Older Men (SOM. Cross validation of self-evaluated data of men in Jamaica was done with comparable samples of the complete JSLC data and the SOM data, where men older than 55 years were selected from each sample.Results: In study 1, 50.2% of respondents indicated at least good self-evaluated health status compared with 74.0% in study 2.

    The time lag between optical and near-infrared continuum emission in active galactic nuclei (AGN) shows a tight correlation with luminosity and has been proposed as a standardizable candle for cosmology. In this paper, we explore the use of these AGN hot-dust time lags for cosmological model fitting under the constraints of the new VISTA Extragalactic Infrared Legacy Survey (VEILS). This new survey will target a 9 deg2 field observed in J and Ks band with a 14-d cadence and will run for 3 yr. The same area will be covered simultaneously in the optical griz bands by the Dark Energy Survey, providing complementary time-domain optical data. We perform realistic simulations of the survey setup, showing that we expect to recover dust time lags for about 450 objects out of a total of 1350 optical type 1 AGN, spanning a redshift range of 0.1 4.

  2. Response rate, response time, and economic costs of survey research: A randomized trial of practicing pharmacists.

    Hardigan, Patrick C; Popovici, Ioana; Carvajal, Manuel J

    2016-01-01

    There is a gap between increasing demands from pharmacy journals, publishers, and reviewers for high survey response rates and the actual responses often obtained in the field by survey researchers. Presumably demands have been set high because response rates, times, and costs affect the validity and reliability of survey results. Explore the extent to which survey response rates, average response times, and economic costs are affected by conditions under which pharmacist workforce surveys are administered. A random sample of 7200 U.S. practicing pharmacists was selected. The sample was stratified by delivery method, questionnaire length, item placement, and gender of respondent for a total of 300 observations within each subgroup. A job satisfaction survey was administered during March-April 2012. Delivery method was the only classification showing significant differences in response rates and average response times. The postal mail procedure accounted for the highest response rates of completed surveys, but the email method exhibited the quickest turnaround. A hybrid approach, consisting of a combination of postal and electronic means, showed the least favorable results. Postal mail was 2.9 times more cost effective than the email approach and 4.6 times more cost effective than the hybrid approach. Researchers seeking to increase practicing pharmacists' survey participation and reduce response time and related costs can benefit from the analytical procedures tested here.

  3. A Classification Scheme for Young Stellar Objects Using the WIDE-FIELD INFRARED SURVEY EXPLORER AllWISE Catalog: Revealing Low-Density Star Formation in the Outer Galaxy

    CERN Document Server

    Koenig, Xavier

    2014-01-01

    We present an assessment of the performance of WISE and the AllWISE data release in a section of the Galactic Plane. We lay out an approach to increasing the reliability of point source photometry extracted from the AllWISE catalog in Galactic Plane regions using parameters provided in the catalog. We use the resulting catalog to construct a new, revised young star detection and classification scheme combining WISE and 2MASS near and mid-infrared colors and magnitudes and test it in a section of the Outer Milky Way. The clustering properties of the candidate Class I and II stars using a nearest neighbor density calculation and the two-point correlation function suggest that the majority of stars do form in massive star forming regions, and any isolated mode of star formation is at most a small fraction of the total star forming output of the Galaxy. We also show that the isolated component may be very small and could represent the tail end of a single mechanism of star formation in line with models of molecul...

  12. Voyeurismo Televisivo, Reality Shows e Brasilidade Televisiva

    OpenAIRE

    Suzana Kilpp

    2008-01-01

    In the last years we watched a boom of reality shows in the media and also in the academic production specialized in this subject. It remains, however, a epistemological gap related to the aesthetic and techniques (which are related to the televisions grammars) that TV uses in these programs to enunciate ethics directions to its own voyeurism, that goes far beyond reality shows, having repercussions on social imaginary of transparency and surveillance, and the redesign of public and private s...

    In January 2004 the Mars Exploration Rover mission will land two rovers at two different landing sites that show possible evidence for past liquid-water activity. The spacecraft design is based on the Mars Pathfinder configuration for cruise and entry, descent, and landing. Each of the identical rovers is equipped with a science payload of two remote-sensing instruments that will view the surrounding terrain from the top of a mast, a robotic arm that can place three instruments and a rock abrasion tool on selected rock and soil samples, and several onboard magnets and calibration targets. Engineering sensors and components useful for science investigations include stereo navigation cameras, stereo hazard cameras in front and rear, wheel motors, wheel motor current and voltage, the wheels themselves for digging, gyros, accelerometers, and reference solar cell readings. Mission operations will allow commanding of the rover each Martian day, or sol, on the basis of the previous sol's data. Over a 90-sol mission lifetime, the rovers are expected to drive hundreds of meters while carrying out field geology investigations, exploration, and atmospheric characterization. The data products will be delivered to the Planetary Data System as integrated batch archives.

  16. Liquid Crystal Research Shows Deformation By Drying

    Science.gov (United States)

    2003-01-01

    These images, from David Weitz's liquid crystal research, show ordered uniform sized droplets (upper left) before they are dried from their solution. After the droplets are dried (upper right), they are viewed with crossed polarizers that show the deformation caused by drying, a process that orients the bipolar structure of the liquid crystal within the droplets. When an electric field is applied to the dried droplets (lower left), and then increased (lower right), the liquid crystal within the droplets switches its alignment, thereby reducing the amount of light that can be scattered by the droplets when a beam is shone through them.

  17. Cerro Prieto geothermal field: exploration during exploitation

    Energy Technology Data Exchange (ETDEWEB)

    1982-07-01

    Geological investigations at Momotombo included photogeology, field mapping, binocular microscope examination of cuttings, and drillhole correlations. Among the geophysical techniques used to investigate the field sub-structure were: Schlumberger and electromagnetic soundings, dipole mapping and audio-magnetotelluric surveys, gravity and magnetic measurements, frequency domain soundings, self-potential surveys, and subsurface temperature determinations. The geochemical program analyzed the thermal fluids of the surface and in the wells. The description and results of exploration methods used during the investigative stages of the Momotombo Geothermal Field are presented. A conceptual model of the geothermal field was drawn from the information available at each exploration phase. The exploration methods have been evaluated with respect to their contributions to the understanding of the field and their utilization in planning further development.
