The community food environment may contribute to obesity by influencing food choice. Store and restaurant audits are increasingly common methods for assessing food environments, but are time consuming and costly. A valid, reliable brief measurement tool is needed. The purpose of this study was to develop and validate reduced-item food environment audit tools for stores and restaurants. Nutrition Environment Measures Surveys for stores (NEMS-S) and restaurants (NEMS-R) were completed in 820 stores and 1,795 restaurants in West Virginia, San Diego, and Seattle. Data mining techniques (correlation-based feature selection and linear regression) were used to identify survey items highly correlated to total survey scores and produce reduced-item audit tools that were subsequently validated against full NEMS surveys. Regression coefficients were used as weights that were applied to reduced-item tool items to generate comparable scores to full NEMS surveys. Data were collected and analyzed in 2008-2013. The reduced-item tools included eight items for grocery, ten for convenience, seven for variety, and five for other stores; and 16 items for sit-down, 14 for fast casual, 19 for fast food, and 13 for specialty restaurants-10% of the full NEMS-S and 25% of the full NEMS-R. There were no significant differences in median scores for varying types of retail food outlets when compared to the full survey scores. Median in-store audit time was reduced 25%-50%. Reduced-item audit tools can reduce the burden and complexity of large-scale or repeated assessments of the retail food environment without compromising measurement quality.

Influences of Sociocultural Factors Within the Clinical Learning Environment on Students' Perceptions of Learning: An Integrative Review.

Science.gov (United States)

Jessee, Mary Ann

A persistent deficit in new graduate nurses' clinical reasoning skill exists. Clinical reasoning is best learned in the sociocultural clinical learning environment (CLE), yet many CLEs fail to engage nursing students in the cognitive work of nursing that promotes development of clinical reasoning. Despite two decades of recommendations to improve CLEs based on students' perceptions of learning, widespread improvement remains elusive. The aim of this review was to synthesize what is known about the influence of sociocultural factors in the acute-care CLE on prelicensure nursing students' perceptions of learning, for the purpose of identifying factors that when modified may promote improvement of clinical reasoning skill. The integrative review methodology was used to synthesize and identify gaps in evidence on students' perceptions of learning in the acute-care CLE. Global commonalities exist in the impact of the sociocultural CLE on students' perceptions of learning, including overall sociocultural atmosphere, membership in the health care team, supervisory relationships, peer relationships, and clinical education structure. This review provides evidence that modification of CLE factors and examination of their influence on measurable learning outcomes such as clinical reasoning are the necessary next steps to facilitate improvement of new graduate nurses' clinical reasoning skill.

Technological learning in energy-environment-economy modelling: A survey

International Nuclear Information System (INIS)

Kahouli-Brahmi, Sondes

2008-01-01

This paper aims at providing an overview and a critical analysis of the technological learning concept and its incorporation in energy-environment-economy models. A special emphasis is put on surveying and discussing, through the so-called learning curve, both studies estimating learning rates in the energy field and studies incorporating endogenous technological learning in bottom-up and top-down models. The survey of learning rate estimations gives special attention to interpreting and explaining the sources of variability of estimated rates, which is shown to be mainly inherent in R and D expenditures, the problem of omitted variable bias, the endogeneity relationship and the role of spillovers. Large-scale models survey show that, despite some methodological and computational complexity related to the non-linearity and the non-convexity associated with the learning curve incorporation, results of the numerous modelling experiments give several new insights with regard to the analysis of the prospects of specific technological options and their cost decrease potential (bottom-up models), and with regard to the analysis of strategic considerations, especially inherent in the innovation and energy diffusion process, in particular the energy sector's endogenous responses to environment policy instruments (top-down models)

The Clinical Learning Environment, Supervision and Nurse Teacher (CLES + T) scale evaluates the student nurses' perception of the learning environment and supervision within the clinical placement. It has never been tested in a replication study. The aim of the present study was to evaluate the test-retest reliability of the CLES + T scale. The CLES + T scale was administered twice to a group of 42 student nurses, with a one-week interval. Test-retest reliability was determined by calculations of Intraclass Correlation Coefficients (ICCs) and weighted Kappa coefficients. Standard Error of Measurements (SEM) and Smallest Detectable Difference (SDD) determined the precision of individual scores. Bland-Altman plots were created for analyses of systematic differences between the test occasions. The results of the study showed that the stability over time was good to excellent (ICC 0.88-0.96) in the sub-dimensions "Supervisory relationship", "Pedagogical atmosphere on the ward" and "Role of the nurse teacher". Measurements of "Premises of nursing on the ward" and "Leadership style of the manager" had lower but still acceptable stability (ICC 0.70-0.75). No systematic differences occurred between the test occasions. This study supports the usefulness of the CLES + T scale as a reliable measure of the student nurses' perception of the learning environment within the clinical placement at a hospital.

Full Text Available Parmi les différentes déclinaisons du terme "frontière" (naturelle, politique, administrative, identitaire, existe-t-il une combinaison d'entre elles qui résisterait le plus farouchement à l'épreuve du temps? Le cas de la France qui, au sein de l'Europe, connaît une exception administrative particulière, est intéressant à observer. Ses nombreuses frontières intérieures ont repoussé avec obstination toute tentative de réduction de leur nombre. Sans doute parce que, laissée à l'initiative des populations locales et respectée par les successifs gouvernements, la définition des territoires s'est appuyée sur la reconnaissance des identités communales construites au cours des siècles par le quotidien des habitants. La correspondance cartographique établie entre le tissu paroissial du XVIIIe siècle en France, et le maillage communal d'aujourd'hui illustre, en dépit des quelques variations observées, la remarquable stabilité de ses frontières administratives.

In Candidate C area for the geothermal development survey, the natural environment was surveyed and `the secondary landscape assessment` was summed up in which places proposed for drilling of large-size wells and for construction of power generation facilities are extracted and a simulation of the landscape is conducted. The area for survey is the Shiramizu-gawa region in the south of Lake Akan, Akan-cho, Akan-gun, Hokkaido. The field survey was carried out about three items of landscape, plants and animals during the June-November period, 1995. As to the flora, diverse florae including vegetation unique to alpine areas, wetlands, and fumarole surrounding areas were found in the region, which is covered with summer-green broad-leaved forests or mixed forests of coniferous and broad-leaved trees. As to the fauna, faunae inhabitant of the highly natural forests were found including black woodpeckers and mountain hawk eagles. As a result of studying the places proposed for geothermal development from the above-mentioned survey, two places were picked up in the west of the survey area, where geothermal development is comparatively less influential in the natural environment and landscape and there is a high locational adaptability. 19 refs., 56 figs., 49 tabs.

Full Text Available Aim: The purpose of the cross-sectional descriptive study was to investigate how nursing students evaluate particular factors of clinical learning environment during their professional placement in hospitals. We explored which factors of clinical environment contribute significantly to students' evaluation of it. Design: A descriptive cross-sectional study. Methods: The sample included 503 nursing students in their second or third year of study at six Slovak universities. A valid and reliable questionnaire, the Clinical Learning Environment, Supervision and Nurse Teacher evaluation scale (CLES+T, was used to evaluate the student nurses' experiences and clinical placement. The data were analysed using descriptive statistics, Pearson's chi-square test, multifactorial ANOVA procedure and Pearsons' correlations, and p-value < 0.05 was taken to indicate statistical significance for all comparisons. Results: A significant proportion of students experienced a traditional model of group supervision. Supervision method, supervisory session frequency, and duration of clinical placement had a significant impact on their evaluation of clinical environments. Conclusion: Supervision methods are a significant factor influencing student evaluation of their clinical placement environment. Compared to other European studies, we found a less frequent application of individual supervision and that the Slovak university setting is dominated by a traditional group model of supervision. The study offers a valuable insight into the analysis of factors contributing to improvements in clinical learning environment and models of clinical or workplace training.

Nursing students perform their clinical practice in different types of clinical settings. The clinical learning environment is important for students to be able to achieve desired learning outcomes. Knowledge is lacking about the learning environment in different clinical settings. The aim was to compare the learning environment in different clinical settings from the perspective of the nursing students. A cross-sectional study with comparative design was conducted. Data was collected from 185 nursing students at three universities by means of a questionnaire involving the Clinical Learning Environment, Supervision and Nurse Teacher (CLES + T) evaluation scale. An open-ended question was added in order to ascertain reasons for dissatisfaction with the clinical placement. The nursing students' satisfaction with the placement did not differ between clinical settings. However, those with clinical placement in hospital departments agreed more strongly that sufficient meaningful learning situations occurred and that learning situations were multi-dimensional. Some students reported that the character of the clinical setting made it difficult to achieve the learning objectives. In the planning of the clinical placement, attention must be paid to whether the setting offers the student a meaningful learning situation where the appropriate learning outcome may be achieved.

The Nuclear Information Centre in Prague took part in the international project surveying the knowledge and opinion of secondary school students. The survey was performed on the initiative of the Japan Atomic Energy Relations Organization (JAERO). It took place in June 1992 simultaneously in seven countries: Japan, France, Germany, Sweden, Switzerland, the United Kingdom and Czechoslovakia. The survey was aimed at finding out the level of acquaintance of secondary school students with issues of the environment, and at determining the attitude of the young to nuclear power. In Czechoslovakia 1030 students aged between 15 and 18 took part in the survey. The questionnaire contained 17 basic questions and a number of more detailed questions. Because of the amount of evaluated answers not all results are given here. The complete evaluation of the survey was handed over to JAERO

Radiometric surveys in underground environment

Due to their ability to travel through the air for several metres, gamma-rays emitted from natural radioactive elements can be successfully used in surveys carried out both with airborne and ground equipments. Besides the concentration of the radio-elements contained in rocks and soils and the intrinsic characteristics of the gamma-ray detector, the detected count rate depends on the solid angle around the spectrometer. On a flat outcrop, ground spectrometry detects the radiation ideally produced by a cylindrical mass of rock of about two metres in diameter and thickness of about half a meter. Under these geometrical conditions, the natural radioactivity can be easily evaluated. With operating conditions different from the standard ones, such as at the edge of an escarpment, the count rate halves because of the missing material, whereas in the vicinity of a rock wall the count rate will increase. In underground environment, the recorded count rate may even double and the in situ assessment of the concentration of radio-elements may be rather difficult, even if the ratios between the different radio-elements may not be affected. We tested the applicability of gamma-ray spectrometry for rapid assessment of the potential hazard levels related to radon and radiation dose rate in underground environment. A mine shaft, located in a zone of uranium enrichment in Liguria (Italy), has been investigated. A preliminary ground radiometric survey was carried out to define the extent of the ore deposit. Then, the radiometric investigation was focussed on the mine shaft. Due to rock mass above the shaft vault, the background gamma radiation can be considered of negligible influence on measurements. In underground surveys, besides deviations from a flat geometry, factors controlling radon exhalation, emanation and stagnation, such as fractures, water leakage and the presence of ventilation, should be carefully examined. We attempted to evaluate these control factors and collected

Activity at the centers of galaxies, during which the central supermassive black hole is accreting material, is nowadays accepted to be rather ubiquitous and most probably a phase of every galaxy's evolution. It has been suggested that galactic mergers and interactions may be the culprits behind the triggering of nuclear activity. We use near-infrared data from the new Infrared Medium-Deep Survey and the Deep eXtragalactic Survey of the VIMOS-SA22 field and radio data at 1.4 GHz from the FIRST survey and a deep Very Large Array survey to study the environments of radio active galactic nuclei (AGNs) over an area of ∼25 deg{sup 2} and down to a radio flux limit of 0.1 mJy and a J-band magnitude of 23 mag AB. Radio AGNs are predominantly found in environments similar to those of control galaxies at similar redshift, J-band magnitude, and (M{sub u} – M{sub r} ) rest-frame color. However, a subpopulation of radio AGNs is found in environments up to 100 times denser than their control sources. We thus preclude merging as the dominant triggering mechanism of radio AGNs. By fitting the broadband spectral energy distribution of radio AGNs in the least and most dense environments, we find that those in the least dense environments show higher radio-loudness, higher star formation efficiencies, and higher accretion rates, typical of the so-called high-excitation radio AGNs. These differences tend to disappear at z > 1. We interpret our results in terms of a different triggering mechanism for these sources that is driven by mass loss through winds of young stars created during the observed ongoing star formation.

Zhang, Mei; Kang, Jian; Jiao, Fenglei

2012-11-01

The aim of this study is to reveal noise impact in open-plan working environments in China, through a series of questionnaire surveys and acoustic measurements in typical open-plan working environments. It has been found that compared to other physical environmental factors in open-plan working environments, people are much less satisfied with the acoustic environment. The noise impact in the surveyed working environments is rather significant, in terms of sound level inside the office, understanding of colleagues' conversation, and the use of background music such as music players. About 30-50% of the interviewees think that various noise sources inside and outside offices are 'very disturbing' and 'disturbing', and the most annoying sounds include noises from outside, ventilation systems, office equipment, and keyboard typing. Using higher panels to separate work space, or working in enclosed offices, are regarded as effective improvement measures, whereas introducing natural sounds to mask unwanted sounds seems to be not preferable. There are significant correlations between the evaluation of acoustic environment and office symptoms, including hypersensitivity to loud sounds, easily getting tired and depression. There are also significant correlations between evaluation of various acoustics-related factors and certain statements relating to job satisfaction, including sensitivity to noise, as well as whether conversations could be heard by colleagues.

2014-05-01

Full Text Available The study combined qualitative approaches with quantitative research design to come up with a survey instrument called Culture-Sensitive Physics Learning Environment Survey (CS-PLES.This survey instrument is intended to extract the learners’ beliefs and expectations on the integration of culture and language in the teaching and learning process of physics concepts. Significant contribution of the instrument can be traced to establishing and defining the constructs and categories on how curriculum localization and context-based science learning can be developed aligned with students’ expectations and beliefs. The development process employed non-conventional processes adopted from literature which included pilot study to identify pre-deterministic constructs and specific categories for the items to be included in the survey. Data analysis included descriptive statistics and factor analysis to establish the categories or constructs of the survey instruments. Reliability measures of the instrument and its respective constructs were established for standardization. These categories were intended to aid researchers for an in-depth analysis when the instrument is administered for its purpose. The raw statistical categories were qualitatively paralleled with the pre-deterministic constructs to establish congruence of the survey tool to Instructional Congruence Framework (ICF.

Full Text Available The use of technology in the classroom may have positive and negative effects on learning. The purpose of this investigation was twofold: to identify the effect technology is having on the pharmacy learning environment; and, to assess students' use of technology during class time for non-academic purposes. This study included a national cross-sectional survey as well as a single, college-specific survey. The national survey had a faculty response rate of 71.2%. Of the responders, approximately 61% identified significant problems related to students' use of technology in the pharmacy learning environment. Cell phones were a recognized concern and more than 90% of programs have chosen to restrict cell phone use in the classroom. The single college survey examining technology use during class for non-academic purposes had a student response rate of 87% and faculty response rate of 100%. Students and faculty members disagreed regarding the negative effects of technology use during class for non-academic purposes. Notably, 16% of students acknowledged their in-class use of technology for non-academic purposes had been disruptive to their learning, as compared to 95.7% of faculty. According to students, common reasons for off-task technology use included checking e-mail/text messages (75.1%, lack of engagement (58.1%, multitasking (56.2%, and accessing social media sites (33%. Faculty and students were asked about enforcement of technology policy. More faculty than students supported policy enforcement by faculty (65.2% versus 22.8%, respectively; p<0.001 as well as policy enforcement by students (78.3% versus 31.9%, respectively; p<0.001. Overall, technology use during class for non-academic purposes was common. Many schools and colleges of pharmacy are developing approaches to address these evolving issues by revising their technology use policies.   Type: Original Research

This paper describes a survey on an environment technology transfer information network. Based on the achievements obtained by the surveys in fiscal 1995 and 1996, the ICETT has participated as one organization constituting the APEC environment technology exchange virtual center, and begun providing information since April 1997. As the environment technology information, those items actually employed by factories and operation sites in Japan are put into a data base, and into a home page including training information centering around those contained in the data base, and examples of works done by local governments for prevention of pollution. Furthermore in fiscal 1997, a simulation software for a model process has been developed. Fiscal 1998 strengthened the data base for environment preservation technology information, investigated environment preserving model companies and summarized them including even their management aspect. Investigations were carried out in developing countries on application of cleaner technologies. Gaps far exceeding anticipation exist in every field between these developing countries and Japan. Environment protection measures applied and succeeded in the developing countries as the means to narrow the gaps were collected, and compiled as the specific examples. (NEDO)

This study examines the relationship between hospital work environments and job satisfaction, job-related burnout and intention to leave among nurses in Guangdong province, China. The nursing shortage is an urgent global problem and also of concern in China. Studies in Western countries have shown that better work environments are associated with higher nurse satisfaction and lower burnout, thereby improving retention and lowering turnover rates. However, there is little research on the relationship between nurse work environments and nurse outcomes in China. This is a cross-sectional study. Survey data were collected from 1104 bedside nurses in 89 medical, surgical and intensive care units in 21 hospitals across the Guangdong province in China. Stratified convenience sampling was used to select hospitals, and systematic sampling was used to select units. All staff nurses working on participating units were surveyed. The China Hospital Nurse Survey, including the Practice Environment Scale of the Nursing Work Index and Maslach Burnout Inventory, was employed to collect data from nurses. Statistical significance level was set at 0·05. Thirty-seven per cent of the nurses experienced high burnout, and 54% were dissatisfied with their jobs. Improving nurses' work environments from poor to better was associated with a 50% decrease in job dissatisfaction and a 33% decrease in job-related burnout among nurses. Burnout and job dissatisfaction are high among hospital nurses in Guangdong province, China. Better work environments for nurses were associated with decreased job dissatisfaction and job-related burnout, which may successfully address the nursing shortage in China. The findings of this study indicate that improving work environments is essential to deal with the nursing shortage; the findings provide motivation for nurse managers and policy makers to improve work environments of hospital nurses in China. © 2012 Blackwell Publishing Ltd.

Novel efforts and accompanying tools are needed to tackle the global burden of chronic disease. This paper presents an approach to describe the environments in which people live, work, and play. Community Health Environment Scan Survey (CHESS) is an empirical assessment tool that measures the availability and accessibility, of healthy lifestyle options lifestyle options. CHESS reveals existing community assets as well as opportunities for change, shaping community intervention planning efforts by focusing on community-relevant opportunities to address the three key risk factors for chronic disease (i.e. unhealthy diet, physical inactivity, and tobacco use). The CHESS tool was developed following a review of existing auditing tools and in consultation with experts. It is based on the social-ecological model and is adaptable to diverse settings in developed and developing countries throughout the world. For illustrative purposes, baseline results from the Community Interventions for Health (CIH) Mexico site are used, where the CHESS tool assessed 583 food stores and 168 restaurants. Comparisons between individual-level survey data from schools and community-level CHESS data are made to demonstrate the utility of the tool in strategically guiding intervention activities. The environments where people live, work, and play are key factors in determining their diet, levels of physical activity, and tobacco use. CHESS is the first tool of its kind that systematically and simultaneously examines how built environments encourage/discourage healthy eating, physical activity, and tobacco use. CHESS can help to design community interventions to prevent chronic disease and guide healthy urban planning. © 2011 Fiona Wong et al.

As part of the regulatory environmental monitoring around its nuclear power plants (NPP) in France, EDF carries out more than 40.000 measurements of radionuclides in the environment every year. In addition, EDF performs more detailed radioecological surveys on all of its sites. The purposes of these surveys are: 1/ to control that radioactive discharge limits prescribed by the regulatory authority are respected, 2/ to monitor the environment of the NPPs to verify normal plant operation and to detect all possible failures in power station operation at an early stage and 3/ to establish if there is any increase of radionuclides of anthropogenic origin in the environment and to determine whether this build-up can be attributed to plant operations. Radioecological surveys are conducted in the environment surrounding each of EDF's NPPs. Samples are collected in surrounding ecosystems (terrestrial and aquatic) where the radioactive releases are discharged (liquid and gaseous discharges). These surveys results enable the examination of the spatial distribution and temporal variability of radionuclide activity in the environment throughout the reactors life, from the first fuel load to the decommissioning of the plant. The results from this monitoring have shown that EDF's nuclear power plants have only a minor effect on radionuclide levels in the environment. These results highlight the efficiency of EDF's efforts to minimise its impacts on the environment via an efficient waste management system and high operating standards of its plants. In particular, tritium is subject to special monitoring for more than 30 years; concentrations of free tritium and organically bound tritium in major environmental compartments are therefore well-known in the vicinity of French NPPs. At the end of a reactor's life, EDF has collected a large amount of reference data before decommissioning operations start. During these operations, EDF pursue the radioecological survey

This pilot study compared second- and fourth-year dental students' perceived values of newly implemented clinical leadership experiences (CLEs) at one U.S. dental school during the 2012-13 academic year. In the CLEs, fourth-year (D4) students mentored second-year (D2) dental students during faculty-supervised patient treatment. The two cohorts' perceived value of the experiences was measured with questionnaires consisting of five-point Likert scale questions and open text responses. Out of a total of 114 D2 and 109 D4 students, 46 D2 students and 35 D4 students participated (response rates of 40.4% and 32.1%, respectively). While responses from both cohorts showed they highly valued the CLEs, the D2s perceived greater value: 4.07 (0.53) v. 3.51 (0.95), pmentor D2s, that the CLEs had educational benefits, and that the CLEs increased their comfort with peer communication. Theme analysis of open text questions revealed that the respondents perceived the D4s were more accessible than faculty and provided guidance and individual attention; the CLEs increased student comfort; the CLEs reinforced D4 skills, knowledge, and confidence; and the CLEs provided management, leadership, and collaborative work experience. Theme analysis also highlighted student concerns about a lack of program structure. Overall, the majority of both groups valued CLEs in their dental education. Particular advantages they perceived were increased comfort, guidance, and attention. Further program development should address student concerns. These results suggest that similar programs should be considered and/or expanded in other dental schools' curricula.

To look over the current measurement of radioactivity concentration in working environment of many radioisotopes facilities, a questionnaire survey was carried out under the auspices of the Planning Committee of the Japan Society of Radiation Safety Management. 64 responses were obtained in 128 radiation facilities, which the questionnaires were sent to. The main results were obtained by aggregate analysis of the answers for questionnaires as the followings. Major nuclides subject to measurement were 3 H, 14 C, 32 P and 125 I Sampling of radioisotopes in air was mainly performed using collectors like dust samplers and HC-collectors. Liquid scintillation counters and gamma counters were used to measure β and γ radioactivity contained in airborne particles or gas samples. Contamination by radioactivity was not detected in 55% facilities surveyed, but in 40% facilities at the same level as or at lower levels than a hundredth part of the regulated concentration limit of each nuclide. Almost all facilities is found to consider that the measurement of radioactivity concentration in working environments is not always necessary. (author)

We developed and tested a College Environmental Perceptions Survey (CEPS) to assess college students' perceptions of the healthfulness of their campus. CEPS was developed in 3 stages: questionnaire development, validity testing, and reliability testing. Questionnaire development was based on an extensive literature review and input from an expert panel to establish content validity. Face validity was established with the target population using cognitive interviews with 100 college students. Concurrent-criterion validity was established with in-depth interviews (N = 30) of college students compared to surveys completed by the same 30 students. Surveys completed by college students from 8 universities (N = 1147) were used to test internal structure (factor analysis) and internal consistency (Cronbach's alpha). After development and testing, 15 items remained from the original 48 items. A 5-factor solution emerged: physical activity (4 items, α = .635), water (3 items, α = .773), vending (2 items, α = .680), healthy food (2 items, α = .631), and policy (2 items, α = .573). The mean total score for all universities was 62.71 (±11.16) on a 100-point scale. CEPS appears to be a valid and reliable tool for assessing college students' perceptions of their health-related campus environment.

Heat pipes today are employed in a wide variety of special heat transfer applications including nuclear reactor. In this nuclear technology area in Japan, A headway speed of the heat pipe application technique is not so high because of safety confirmation and investigation under each developing step. Especially, the outline of space craft is a tendency to increase the size. Therefore, the power supply is also tendency to increase the outlet power and keep the long life. Under SP-100 project, the development of nuclear power supply system which power is 1400 - 1600 KW thermal and 100 KW electric power is steadily in progress. Many heat pipes are adopted for thermionic conversion and coolant system in order to construct more safety and light weight system for the project. This paper describes the survey of the heat pipe applications under the present and future condition for nuclear environment. (author)

We describe a new Large Program in progress on the Gemini North and South telescopes: Gemini Observations of Galaxies in Rich Early Environments (GOGREEN). This is an imaging and deep spectroscopic survey of 21 galaxy systems at 1 10 in halo mass. The scientific objectives include measuring the role of environment in the evolution of low-mass galaxies, and measuring the dynamics and stellar contents of their host haloes. The targets are selected from the SpARCS, SPT, COSMOS, and SXDS surveys, to be the evolutionary counterparts of today's clusters and groups. The new red-sensitive Hamamatsu detectors on GMOS, coupled with the nod-and-shuffle sky subtraction, allow simultaneous wavelength coverage over λ ˜ 0.6-1.05 μm, and this enables a homogeneous and statistically complete redshift survey of galaxies of all types. The spectroscopic sample targets galaxies with AB magnitudes z΄ < 24.25 and [3.6] μm < 22.5, and is therefore statistically complete for stellar masses M* ≳ 1010.3 M⊙, for all galaxy types and over the entire redshift range. Deep, multiwavelength imaging has been acquired over larger fields for most systems, spanning u through K, in addition to deep IRAC imaging at 3.6 μm. The spectroscopy is ˜50 per cent complete as of semester 17A, and we anticipate a final sample of ˜500 new cluster members. Combined with existing spectroscopy on the brighter galaxies from GCLASS, SPT, and other sources, GOGREEN will be a large legacy cluster and field galaxy sample at this redshift that spectroscopically covers a wide range in stellar mass, halo mass, and clustercentric radius.

Antimicrobial resistance has become an urgent global health priority. Basic hygiene practices and cleaning and disinfection of the hospital environment are key in preventing pathogen cross-transmission. To our knowledge no studies have assessed the worldwide differences in cleaning and disinfection practices in healthcare facilities. The electronic survey described here was developed in order to evaluate differences in healthcare facility cleaning practices around the world. The International Society of Antimicrobial Chemotherapy (ISAC, formerly ISC), Infection Prevention and Control work group developed a survey with 30 multiple-choice questions. The questions were designed to assess the current cleaning practices in healthcare settings around the world. A total of 110 healthcare professionals, representing 23 countries participated in the online survey. In 96% of the facilities a written cleaning policy was present. Training of cleaning staff occurred in 70% of the facilities at the start of employment. Cleaning practices and monitoring of these practices varied. In summary, the survey enabled assessment and recognition of widely differing global practices in approaches to environmental cleaning and disinfection. Development of guideline recommendations for cleaning and disinfection could improve practices and set minimum standards worldwide. Copyright © 2018 The Healthcare Infection Society.

This report summarizes the result on selecting sites for large-caliber production wells, and landscape characteristic evaluation for simulation, based on the landscape survey on C candidate site for geothermal development. Field survey was made on landscape, plants and animals in the Kirishima Eboshidake area. It was clarified that this area has diverse flora including some rare species such as rein orchid and monkshood which are listed as endangered species. In addition, not a few epiphytes were identified. The zoological survey result showed that planted forests of evergreen coniferous trees which cover a wide range of the surveyed area, and peripheral grassland, scrub and natural forests provide good habitats for mammals such as sika deer and wild boars. On the other hand, no animal species in need of special protection were found. Geologically some traces of landslide occurrence in the past were detected in the northern part of the surveyed area relatively. As the survey result, some promising sites suitable for geothermal development were selected, which are judged to have a relatively small impact on natural environment and landscape. (NEDO)

A practical, reliable, and valid instrument is needed to measure the impact of the learning environment on medical students' well-being and educational experience and to meet medical school accreditation requirements. From 2012 to 2015, medical students were surveyed at the end of their first, second, and third year of studies at four medical schools. The survey assessed students' perceptions of the following nine dimensions of the school culture: vitality, self-efficacy, institutional support, relationships/inclusion, values alignment, ethical/moral distress, work-life integration, gender equity, and ethnic minority equity. The internal reliability of each of the nine dimensions was measured. Construct validity was evaluated by assessing relationships predicted by our conceptual model and prior research. Assessment was made of whether the measurements were sensitive to differences over time and across institutions. Six hundred and eighty-six students completed the survey (49 % women; 9 % underrepresented minorities), with a response rate of 89 % (range over the student cohorts 72-100 %). Internal consistency of each dimension was high (Cronbach's α 0.71-0.86). The instrument was able to detect significant differences in the learning environment across institutions and over time. Construct validity was supported by demonstrating several relationships predicted by our conceptual model. The C-Change Medical Student Survey is a practical, reliable, and valid instrument for assessing the learning environment of medical students. Because it is sensitive to changes over time and differences across institution, results could potentially be used to facilitate and monitor improvements in the learning environment of medical students.

The aim of this study was to conduct a survey of Surgical Oncologists to identify their perceptions of the current state of Oncology education in India. Methods An Institutional Review Board approved questionnaire was developed to target the audience of the 2009 annual meeting of the Indian Association of Surgical Oncology in India. The survey collected demographic information and asked respondents to provide their opinions about Oncology education in India. Results A total of 205 out of 408 attendee's participated in the survey with a 42.7% response rate. The majority of respondents felt that Oncology education was poor to fair during medical school (75%, residency (56% and for practicing physicians (71%. The majority of participants also felt that the quality of continuing medical education was poor and that minimal emphasis was placed on evidence based medicine. Conclusions The results of our survey demonstrate that the majority of respondents feel that the current educational environment for Oncology in India should be enhanced. The study identified perceptions of several gaps and needs, which can be the targets for implementing measures to enhance the training of Oncology professionals.

A canopy architectural model to study the competitive ability of chickpea with sowthistle.

Cici, S-Zahra-Hosseini; Adkins, Steve; Hanan, Jim

Improving the competitive ability of crops is a sustainable method of weed management. This paper shows how a virtual plant model of competition between chickpea (Cicer arietinum) and sowthistle (Sonchus oleraceus) can be used as a framework for discovering and/or developing more competitive chickpea cultivars. The virtual plant models were developed using the L-systems formalism, parameterized according to measurements taken on plants at intervals during their development. A quasi-Monte Carlo light-environment model was used to model the effect of chickpea canopy on the development of sowthistle. The chickpea-light environment-sowthistle model (CLES model) captured the hypothesis that the architecture of chickpea plants modifies the light environment inside the canopy and determines sowthistle growth and development pattern. The resulting CLES model was parameterized for different chickpea cultivars (viz. 'Macarena', 'Bumper', 'Jimbour' and '99071-1001') to compare their competitive ability with sowthistle. To validate the CLES model, an experiment was conducted using the same four chickpea cultivars as different treatments with a sowthistle growing under their canopy. The growth of sowthistle, both in silico and in glasshouse experiments, was reduced most by '99071-1001', a cultivar with a short phyllochron. The second rank of competitive ability belonged to 'Macarena' and 'Bumper', while 'Jimbour' was the least competitive cultivar. The architecture of virtual chickpea plants modified the light inside the canopy, which influenced the growth and development of the sowthistle plants in response to different cultivars. This is the first time that a virtual plant model of a crop-weed interaction has been developed. This virtual plant model can serve as a platform for a broad range of applications in the study of chickpea-weed interactions and their environment.

Nursing clinical learning environments are particularly important for the achievement of good practice in clinical training of student nurses, and thus, for the nursing competence development. Hence, it is important to have an instrument consisting of reliable and valid criteria for assessing the clinical learning environment, applicable in different contexts, and translated in the respondents mother tongue. The goal of the present research was to test the reliability and validity of the Slovenian version of the "Clinical Learning Environment, Supervision and Nurse Teacher evaluation scale", and to compare it with the Croatian version. The data was collected between 10 March and 10 June 2015 at four Slovenian institutions, where nursing BSc study programmes are performed. The final sample consisted of 232 students (response rate 68.8%): 81.9% were females and 18.1% males, average age was 23. The translated instrument in Slovenian language resulted as reliable and valid, it reflects the expected five factors of the original version despite some minor problems in the factor structure and in test-retest. The most important difference between the Slovenian and Croatian version is in the factor structure regarding the implementation of roles in clinical learning environment.

Our research is based on an integration of quantitative and qualitative approaches, deigned to provide a wider ranging and deeper understanding. Eight hundred and forty eighth- and ninth-grade students from over 15 schools participated in the study. Of the 840 students who completed the questionnaire, the explanations of 200 well-written questionnaires were further analyzed qualitatively. The findings of the study are presented in terms of the four scales employed in the CLES, namely the autonomy scale, the prior knowledge scale, the negotiation scale, and the student-centeredness scale. The quantitative results achieved here concur with parallel studies conducted around the world. The findings indicate that a considerable portion of the students perceive their learning environment as a constructivist one and report positive attitudes toward the way they are being taught. In terms of the qualitative results, however, it appears that in some cases, the students' explanations reveal that in fact, and contrary to the bare quantitative results, some students do not perceive their learning environment as being constructivist. This raises the question of whether the fact that students recognize the factors associated with constructivist teaching is indeed an indication that such teaching exists in practice. This finding emphasizes the importance of combining qualitative and quantitative methods for arriving at a balanced view of classroom occurrences.

Statistical survey of the consumption of the products from seminatural environment in the Czech Republic

The central aspect of the work in international project SAVEC (Spatial Analysis of Vulnerable Ecosystems in Central Europe) is the identification of vulnerable areas. These are areas which, by virtue of the processes governing the transfer of radionuclides through food- chains, deliver high radionuclide fluxes to man. Identification of vulnerable areas is essential in establishing where intervention levels are likely to be exceeded in the event of a nuclear accident. Vulnerable areas could be identified using many criteria, a.o. high production rates of certain foodstuffs which substantially accumulate specific radionuclide. In addition to environmental factors, social factors will also contribute to vulnerability, in particular, dietary preferences can lead to the ingestion of more contaminated foodstuffs. Since Chernobyl accident, it is well known fact that in the Czech Republic, the most contaminated foodstuff is coming from semi-natural ecosystem (mushroom, forest berries and game). However, critical group as to the size and composition was not quantitatively evaluated up to now. Therefore, in the frame of SAVEC project, a statistical survey with the aim of finding critical group of inhabitants in the Czech Republic was performed. The survey was performed by a specialised marketing agency AMASIA. It was aimed at the consumption of products from semi-natural environment -mushrooms, forest berries and game. Two independent sub-surveys were performed. The first one, aimed at randomly selected households from phone directory, had a goal to obtain 1500 interviews among the whole population. In individual regions, number of respondent was selected according to the number of inhabitants of the region. The second survey was aimed at the hunters and their households. Mostly members of the hunting association were included into survey as there is only small number of professional hunters in the Czech Republic. The criterion was chosen that the respondent has to be hunter

3. Neural changes in different gravity and ecophysiological environments - A survey

Science.gov (United States)

Slenzka, K.

Neural changes or neuronal plasticity occur after and during different stimulations and inputs in general. Gravity is one major input to the brain transferred from the vestibular system. However, often also direct effects of gravity on the cellular level are discussed. Our group was investigating the influence of different gravity environments on a large variety of neuronal enzymes in the developing fish brain. Long-term space travel or bases on Moon and Mars will have to deal not only with neural changes based on the different gravity environment, but also with potential negative or even toxic changes in the respective life support system. Our goal is now to identify reported enzyme activity changes in the brain based for example on potential toxic drugs or endocrine disruptors in combination with gravity induced changes. In this paper a survey will be undertaken discussing recent results obtained in ecotoxicology, gravitational biology combined with new data from our group regarding potential differences in brain glucose-6-phosphate dehydrogenase of medaka and zebrafish.

Social science literature on the environment: review and prospects for energy studies. A preliminary literature survey

Much of the social science literature on environment is of recent origin and represents the response of the social science research community to a complex societal problem in which technology is a major factor. Energy represents another such problem to which the social science research community is now turning its attention. Because energy problems and environment problems have some similarities and because energy-conversion processes have large effects on the environment, a review of the social science literature on environment was undertaken. The purposes of this review are as follows: (1) to study the possible utility in energy research of some of the concepts developed in social science research on the environment; (2) to study the possible utility in energy research of some of the methodologies utilized in social science research on the environment; and (3) to study the extent to which the results of social science research on the environment have contributed to the development of policy. The first two items above receive major attention in this preliminary literature survey. 50 references.

The Residents' Barometer 2010 is a survey on the quality of Finnish residential environments in settlements with a population of 10,000 or more. The survey was carried out in cooperation with Statistics Finland. Implemented for the third time, the Residents' Barometer is used by the environmental administration to monitor the quality of the living environment. The first Residents' Barometer survey was conducted in 1998, and the second in 2004. While the majority of questions remained the same, new topical questions were included, such as those on the environmental friendliness of housing choices. In general, residents are highly satisfied with their living environment: of the respondents, 97 per cent find their residential area pleasant and the degree of satisfaction has increased. Key factors in this include peacefulness, natural environment, location and transport connections, alongside the supply of services and leisure activities. Factors causing most discomfort are traffic-related disturbances and problems. The supply of basic services in residential areas remained largely unchanged in large, densely populated areas targeted by the survey. The most sought-after additional services include a grocery store, other shops and public transport. There was a considerable decline in the number of people wishing for banking and postal services, whereas the number of those expressing the desire for public transport almost doubled. In general, people are satisfied with parks and outdoor recreation areas and more dissatisfied with the condition of their yards. Residents of densely built areas with blocks of flats, particularly residents of rented apartments, are most dissatisfied with their yard. Car ownership, the possibility to use a car, and using a car for commuting to work and shops has become more common, as the share of walking and public transport has decreased. The average distance commuted to work has increased. Dissatisfaction with public

Solid Lubricants and Coatings for Extreme Environments: State-of-the-Art Survey

Science.gov (United States)

Miyoshi, Kazuhisa

2007-01-01

An investigation was conducted to survey anticipated requirements for solid lubricants in lunar and Martian environments, as well as the effects of these environments on lubricants and their performance and durability. The success of habitats and vehicles on the Moon and Mars, and ultimately, of the human exploration of and permanent human presence on the Moon and Mars, are critically dependent on the correct and reliable operation of many moving mechanical assemblies and tribological components. The coefficient of friction and lifetime of any lubricant generally vary with the environment, and lubricants have very different characteristics under different conditions. It is essential, therefore, to select the right lubrication technique and lubricant for each mechanical and tribological application. Several environmental factors are hazardous to performance integrity on the Moon and Mars. Potential threats common to both the Moon and Mars are low ambient temperatures, wide daily temperature swings (thermal cycling), solar flux, cosmic radiation, and large quantities of dust. The surface of Mars has the additional challenges of dust storms, winds, and a carbon dioxide atmosphere. Solid lubricants and coatings are needed for lunar and Martian applications, where liquid lubricants are ineffective and undesirable, and these lubricants must perform well in the extreme environments of the Moon, Mars, and space, as well as on Earth, where they will be assembled and tested. No solid lubricants and coatings and their systems currently exist or have been validated that meet these requirements, so new solid lubricants must be designed and validated for these applications.

This paper reports on the results of a questionnaire survey on sleeping thermal environment and bedroom air conditioning in high-rise residential buildings in Hong Kong. The survey aimed at investigating the current situation of sleeping thermal environment and bedroom air conditioning, in order to gather relevant background information to develop strategies for bedroom air conditioning in the subtropics. It focused on the use patterns and types of bedroom air conditioning systems used, human factors such as the use of bedding and sleep wear during sleep, preference for indoor air temperature settings in bedrooms, ventilation control at nighttime with room air conditioner (RAC) turned on, etc. The results of the survey showed that most of the respondents would prefer a relatively low indoor air temperature at below 24 {sup o}C. Most of the respondents might however not be satisfied with the indoor air quality (IAQ) in bedrooms in Hong Kong. On the other hand, 68% of the respondents did not use any ventilation control intentionally during their sleep with their RACs turned on. A lack of knowledge of the ventilation control devices provided on window type room air conditioners (WRACs) indicated an urgent need for user education. (author)

To correlate workgroup engagement in nursing teams and the clinical learning experience of nursing students. Work engagement plays a pivotal role in explaining motivational dynamics. Nursing education is workplace-based and, through their clinical placements, nursing students develop both their clinical competences and their professional identity. However, there is currently a lack of evidence on the role of work engagement related to students' learning experiences. A total of 519 nurses and 519 nursing students were enrolled in hospital settings. The Utrecht Work Engagement Scale (UWES) was used to assess work engagement, and the Clinical Learning Environment and Supervision plus nurse Teacher (CLES+T) scale was used to assess students' learning experience. A multilevel linear regression analysis was performed. Group-level work engagement of nurses correlated with students' clinical learning experience (β = 0.11, P learning (respectively, β = 0.37, P education. Nursing education institutions and health-care settings need to conjointly work to build effective organisational climates.

Security, environment, and economic concerns are commonly identified as three major objectives of energy policy. State and federal governments have set aggressive targets for carbon emissions reductions and for alternative fuel use and increased vehicle efficiency to reduce petroleum consumption. Moreover, jobs creation and GDP growth are often cited as key drivers for energy policies. Previous studies on energy policy decision-making have examined the process for developing and evaluating options using multi-criteria decision analysis tools. In addition, energy opinion polls have either elicited preferences between two goals or whether the public supports a specific policy action. In this article, we report results from a survey of 884 members of professional membership organizations on how the U.S. should prioritize energy policy across the goals of energy supply security, environment and climate, and economics and job creation. The majority favor policymaking that is balanced across all three. Security and economic concerns increase with age for male respondents, whereas environment is the highest priority for females regardless of age. Unlike previous surveys that target the general public and focus on a particular objective or technology, these results provide an example of eliciting a portfolio allocation across multiple energy policy goals from targeted constituents. - Highlights: • We surveyed 884 members of professional membership organizations on how the U.S. should prioritize energy policy. • The paper addresses direct elicitation of energy policy goal portfolio allocation for a large set of energy stakeholders. • The majority of respondents favor policymaking balanced across multiple goals. • We observed differences in priorities based on age and gender. • Respondents expressed a tension in allocating across goals that are interrelated

This study presents a Quality of Life (QoL) survey to understand the influence of the housing environment and needs of residents from different housing sectors. The research focuses on Hong Kong where living conditions have become the main affect for people's QoL. Through a household survey using a standard instrument "Word Health Organisation (WHO) Quality of Life-BREF", the article found that among the four WHO QoL domains (Physical Health, Psychological Health, Social Relations And Environment), Environment, particularly its constitute aspect housing environment was the most influential factor for overall quality of life for the public rental housing sector where low-income people live. This research also found that different groups of people have differing needs of their housing environments: the low-income group needs better location and privacy while the medium and high-income groups need better architectural quality. Based on differentiating their needs and wants, this research argues for prioritizing the low-income group's needs for effectively improving their QoL.

U.S. Geological Survey Science at the Intersection of Health and Environment

People worldwide worry about how their environment affects their health, and expect scientists to help address these concerns. The OneHealth concept recognizes the crucial linkages between environment, human health, and health of other organisms. Many US Geological Survey science activities directly examine or help inform how the Earth and the environment influence toxicological and infectious diseases. Key is our ability to bring to bear a collective expertise in environmental processes, geology, hydrology, hazards, microbiology, analytical chemistry, ecosystems, energy/mineral resources, geospatial technologies, and other disciplines. Our science examines sources, environmental transport and fate, biological effects, and human exposure pathways of many microbial (e.g. bacteria, protozoans, viruses, fungi), inorganic (e.g. asbestos, arsenic, lead, mercury) and organic (e.g. algal toxins, pesticides, pharmaceuticals) contaminants from geologic, anthropogenic, and disaster sources. We develop new laboratory, experimental, and field methods to analyze, model, and map contaminants, to determine their baseline and natural background levels, and to measure their biological effects. We examine the origins, environmental persistence, wildlife effects, and potential for transmission to humans of pathogens that cause zoonotic or vector-borne diseases (e.g., avian influenza or West Nile virus). Collaborations with human health scientists from many organizations are essential. For example, our work with epidemiologists and toxicologists helps understand the exposure pathways and roles of geologically sourced toxicants such as arsenic (via drinking water) and asbestos (via dusts) in cancer. Work with pulmonologists and pathologists helps clarify the sources and fate of inhaled mineral particles in lungs. Wildlife health scientists help human health scientists assess animals as sentinels of human disease. Such transdisciplinary science is essential at the intersection of health

Despite the majority of RNs perceiving a shortage of nurses, findings from the 2008 National Survey of RNs indicate the hospital workplace improved in several areas compared to a 2006 survey. Improvements included the time RNs spend with patients, quality of nursing care, and a decreasing impact of the shortage on delaying nurses' responses to pages or calls, staff communication, patients' wait time for surgery, and timeliness and efficiency of care. Areas the environment was perceived to have worsened included overtime hours, sexual harassment/hostile, and physical violence. RNs hold mixed views about the consequences of reporting errors and mistakes with a majority agreeing that reporting them had led to positive changes to prevent future errors, but that mistakes were held against them. Overall, results suggest that hospital managers can be reassured that their efforts to improve the workplace environment are having their intended effect but, at the same time, important areas for improvement remain.

This paper presents a model for the type of classroom environment believed to facilitate scientific conceptual change. A survey based on this model contains items about students' motivational beliefs, their study approach and their perceptions of their teacher's actions and learning goal orientation. Results obtained from factor analyses, correlations and analyses of variance, based on responses from 113 students, suggest that an empowering interpersonal teacher-student relationship is related to a deep approach to learning, a positive attitude to science, and positive self-efficacy beliefs, and may be increased by a constructivist approach to teaching.

A survey was conducted on 'what attractive research environment is for young researchers' as a theme. The young researchers are referred to as those who are registered on a master's or doctor's degree courses and what is called postdoctoral scholars who received a doctor's degree. In the survey, a few common comments were seen in over interviews on the U.S. research environment. The comments were such that, needless to say, subsidies are indispensable for researches but economic aspects of treatment are not necessarily satisfactory, that the research environment is generally good, allowing freedom in research, and that results tend to be achieved by providing a subsidy for experienced knowledgeable researchers rather than directly subsidizing young researchers with a large sum, while programs with individuality such as a fellowship are desired more. It is apparent that the interests of postdoctoral scholars are economic stability; in fact, uneasiness and dissatisfaction in the status and the treatment are pointed out in a survey by the U.S. Science Academy.

The dependence of galaxy clustering on tidal environment in the Sloan Digital Sky Survey

Science.gov (United States)

Paranjape, Aseem; Hahn, Oliver; Sheth, Ravi K.

2018-06-01

The influence of the Cosmic Web on galaxy formation and evolution is of great observational and theoretical interest. We investigate whether the Cosmic Web leaves an imprint in the spatial clustering of galaxies in the Sloan Digital Sky Survey (SDSS), using the group catalogue of Yang et al. and tidal field estimates at ˜2 h-1 Mpc scales from the mass-tides-velocity data set of Wang et al. We use the tidal anisotropy α (Paranjape et al.) to characterize the tidal environment of groups, and measure the redshift-space 2-point correlation function (2pcf) of group positions and the luminosity- and colour-dependent clustering of group galaxies using samples segregated by α. We find that all the 2pcf measurements depend strongly on α, with factors of ˜20 between the large-scale 2pcf of objects in the most and least isotropic environments. To test whether these strong trends imply `beyond halo mass' effects for galaxy evolution, we compare our results with corresponding 2pcf measurements in mock catalogues constructed using a halo occupation distribution that uses only halo mass as an input. We find that this prescription qualitatively reproduces all observed trends, and also quantitatively matches many of the observed results. Although there are some statistically significant differences between our `halo mass only' mocks and the data - in the most and least isotropic environments - which deserve further investigation, our results suggest that if the tidal environment induces additional effects on galaxy properties other than those inherited from their host haloes, then these must be weak.

Doran, Diane; Clarke, Sean; Hayes, Laureen; Nincic, Vera

2014-09-01

Much has been written about interventions to improve the nursing work environment, yet little is known about their effectiveness. A Delphi survey of nurse experts was conducted to explore perceptions about workplace interventions in terms of feasibility and likelihood of positive impact on nurse outcomes such as job satisfaction and nurse retention. The interventions that received the highest ratings for likelihood of positive impact included: bedside handover to improve communication at shift report and promote patient-centred care; training program for nurses in dealing with violent or aggressive behaviour; development of charge nurse leadership team; training program focused on creating peer-supportive atmospheres and group cohesion; and schedule that recognizes work balance and family demands. The overall findings are consistent with the literature that highlights the importance of communication and teamwork, nurse health and safety, staffing and scheduling practices, professional development and leadership and mentorship. Nursing researchers and decision-makers should work in collaboration to implement and evaluate interventions for promoting practice environments characterized by effective communication and teamwork, professional growth and adequate support for the health and well-being of nurses.

Clinical learning environments are defined as an interactive network of forces within the clinical context that influence students' learning outcomes. Nursing students' satisfaction could be strictly related to their learning outcomes. Aim. To analyze the first year nursing students' clinical learning experience and to identify the main determinants of students' satisfaction. The observational study was carried out in five Italian nursing degree courses. 420 students filled out the validated Italian version of the "Clinical Learning Environment and Supervision plus Nurse Teacher (CLES+T) scale" after the conclusion of their first clinical placement. The mean values of the main sub-dimensions of CLES+T varied from 4.02 (pedagogical atmosphere) to 3.30 (supervisory relationship). Students were mainly satisfied with their clinical placement, however the findings showed statistical significantly differences among the five nursing courses. The main determinants of the overall students' satisfaction are the nurse manager's leadership style and the integration between theoretical knowledge and everyday practice of nursing through the relationship among students, clinical tutors and nurse teacher. Our results may contribute to better understand nursing students' perception of their first clinical placement. However, further research are needed to evaluate which organizational factors and clinical training models may enhance the clinical learning experience.

In this paper, we analysed differences in the numbers of wintering birds between rural and urban areas in Poland. We also analysed species richness and abundance in relation to longitude, latitude, human population size, and landscape structure. All these parameters were analysed using modern statistical techniques incorporating species detectability. We counted birds in 156 squares (0.25 km2 each) in December 2012 and again in January 2013 in locations in and around 26 urban areas across Poland (in each urban area we surveyed 3 squares and 3 squares in nearby rural areas). The influence of twelve potential environmental variables on species abundance and richness was assessed with Generalized Linear Mixed Models, Principal Components and Detrended Correspondence Analyses. Totals of 72 bird species and 89,710 individual birds were recorded in this study. On average (± SE) 13.3 ± 0.3 species and 288 ± 14 individuals were recorded in each square in each survey. A formal comparison of rural and urban areas revealed that 27 species had a significant preference; 17 to rural areas and 10 to urban areas. Moreover, overall abundance in urban areas was more than double that of rural areas. There was almost a complete separation of rural and urban bird communities. Significantly more birds and more bird species were recorded in January compared to December. We conclude that differences between rural and urban areas in terms of winter conditions and the availability of resources are reflected in different bird communities in the two environments.

Near surface geophysics applications are gaining more widespread use in geotechnical and engineering projects. The development of data acquisition, processing tools and interpretation methods have optimized survey time, reduced logistics costs and increase results reliability of seismic surveys during the last decades. However, the use of wide-scale geophysical methods under urban environments continues to face great challenges due to multiple noise sources and obstacles inherent to cities. A seismic pre-investigation was conducted to investigate the feasibility of using seismic methods to obtain information about the subsurface layer locations and media properties in Copenhagen. Such information is needed for hydrological, geotechnical and groundwater modeling related to the Cityringen underground metro project. The pre-investigation objectives were to validate methods in an urban environment and optimize field survey procedures, processing and interpretation methods in urban settings in the event of further seismic investigations. The geological setting at the survey site is characterized by several interlaced layers of clay, till and sand. These layers are found unevenly distributed throughout the city and present varying thickness, overlaying several different unit types of limestone at shallow depths. Specific results objectives were to map the bedrock surface, ascertain a structural geological framework and investigate bedrock media properties relevant to the construction design. The seismic test consisted of a combined seismic reflection and refraction analyses of a profile line conducted along an approximately 1400 m section in the northern part of Copenhagen, along the projected metro city line. The data acquisition was carried out using a 192 channels array, receiver groups with 5 m spacing and a Vibroseis as a source at 10 m spacing. Complementarily, six vertical seismic profiles (VSP) were performed at boreholes located along the line. The reflection

Full Text Available BACKGROUND: Psychiatry has been consistently shown to be a profession characterised by 'high-burnout'; however, no nationwide surveys on this topic have been conducted in Japan. AIMS: The objective of this study was to estimate the prevalence of burnout and to ascertain the relationship between work environment satisfaction, work-life balance satisfaction and burnout among psychiatrists working in medical schools in Japan. METHOD: We mailed anonymous questionnaires to all 80 psychiatry departments in medical schools throughout Japan. Work-life satisfaction, work-environment satisfaction and social support assessments, as well as the Maslach Burnout Inventory (MBI, were used. RESULTS: Sixty psychiatric departments (75.0% responded, and 704 psychiatrists provided answers to the assessments and MBI. Half of the respondents (n = 311, 46.0% experienced difficulty with their work-life balance. Based on the responses to the MBI, 21.0% of the respondents had a high level of emotional exhaustion, 12.0% had a high level of depersonalisation, and 72.0% had a low level of personal accomplishment. Receiving little support, experiencing difficulty with work-life balance, and having less work-environment satisfaction were significantly associated with higher emotional exhaustion. A higher number of nights worked per month was significantly associated with higher depersonalisation. CONCLUSIONS: A low level of personal accomplishment was quite prevalent among Japanese psychiatrists compared with the results of previous studies. Poor work-life balance was related to burnout, and social support was noted to mitigate the impact of burnout.

Hemodialysis patients' ability to access food that is both compatible with a renal diet and affordable is affected by the local food environment. Comparisons of the availability and cost of food items suitable for the renal diet versus a typical unrestricted diet were completed using the standard Nutrition Environment Measures Survey and a renal diet-modified Nutrition Environment Measures Survey. Cross-sectional study. Twelve grocery stores in Northeast Ohio. Availability and cost of food items in 12 categories. The mean total number of food items available differed significantly (P ≤ .001) between the unrestricted diet (38.9 ± 4.5) and renal diet (32.2 ± 4.7). The mean total cost per serving did not differ significantly (P = 0.48) between the unrestricted diet ($5.67 ± 2.50) and renal diet ($5.76 ± 2.74). The availability of renal diet food items is significantly less than that of unrestricted diet food items, but there is no difference in the cost of items that are available in grocery stores. Further work is needed to determine how to improve the food environment for patients with chronic diseases. Copyright © 2017 National Kidney Foundation, Inc. Published by Elsevier Inc.

Downs Shauna M

2011-06-01

Full Text Available Abstract Background Although the mandate of recreational facilities is to enhance well-being, many offer foods inconsistent with recommendations for healthy eating. Little is known regarding recreational facility food environments and how they might be improved, as few studies exist. The Alberta Nutrition Guidelines for Children and Youth (ANGCY are intended to ensure access to healthy food choices in schools, childcare and recreational facilities. This study investigated awareness, adoption and implementation of the ANGCY among recreational facilities in Alberta, Canada, one year following their release. Methods A cross-sectional telephone survey was conducted from June - December, 2009 (n = 151 with managers of publicly funded recreational facilities that served food. The questionnaire included 10 closed and 7 open ended questions to assess the organizational priority for healthy eating, awareness, adoption and implementation of the ANGCY. Chi-squared tests examined quantitative variables, while qualitative data were analysed using directed content analysis. Greenhalgh's model of diffusion of complex innovations within health service organizations constituted the theoretical framework for the study. Results One half of respondents had heard of the ANGCY, however their knowledge of them was limited. Although 51% of facilities had made changes to improve the nutritional quality of foods offered in the past year, only a small fraction (11% of these changes were motivated by the ANGCY. At the time of the survey, 14% of facilities had adopted the ANGCY and 6% had implemented them. Barriers to adoption and implementation were primarily related to perceived negative attributes of the ANGCY, the inner (organizational context, and negative feedback received during the implementation process. Managers strongly perceived that implementing nutrition guidelines would limit their profit-making ability. Conclusions If fully adopted and implemented, the ANGCY

Full Text Available Abstract Background Few measures exist to measure the overall home environment for its ability to support physical activity (PA and healthy eating in overweight children. The purpose of this study was to develop and test the reliability and validity of such a measure. Methods The Home Environment Survey (HES was developed to reflect availability, accessibility, parental role modelling, and parental policies related to PA resources, fruits and vegetables (F&V, and sugar sweetened drinks and snacks (SS. Parents of overweight children (n = 219 completed the HES and concurrent behavioural assessments. Children completed the Block Kids survey and wore an accelerometer for one week. A subset of parents (n = 156 completed the HES a second time to determine test-retest reliability. Finally, 41 parent dyads living in the same home (n = 41 completed the survey to determine inter-rater reliability. Initial psychometric analyses were completed to trim items from the measure based on lack of variability in responses, moderate or higher item to scale correlation, or contribution to strong internal consistency. Inter-rater and test-retest reliability were completed using intraclass correlation coefficients. Validity was assessed using Pearson correlations between the HES scores and child and parent nutrition and PA. Results Eight items were removed and acceptable internal consistency was documented for all scales (α = .66–84 with the exception of the F&V accessibility. The F&V accessibility was reduced to a single item because the other two items did not meet reliability standards. Test-retest reliability was high (r > .75 for all scales. Inter-rater reliability varied across scales (r = .22–.89. PA accessibility, parent role modelling, and parental policies were all related significantly to child (r = .14–.21 and parent (r = .15–.31 PA. Similarly, availability of F&V and SS, parental role modelling, and parental policies were related to child (r

We characterize the environments of local accreting supermassive black holes by measuring the clustering of AGNs in the Swift/BAT Spectroscopic Survey (BASS). With 548 AGN in the redshift range 0.01 2MASS galaxies, and interpreting it via halo occupation distribution and subhalo-based models, we constrain the occupation statistics of the full sample, as well as in bins of absorbing column density and black hole mass. We find that AGNs tend to reside in galaxy group environments, in agreement with previous studies of AGNs throughout a large range of luminosity and redshift, and that on average they occupy their dark matter halos similar to inactive galaxies of comparable stellar mass. We also find evidence that obscured AGNs tend to reside in denser environments than unobscured AGNs, even when samples were matched in luminosity, redshift, stellar mass, and Eddington ratio. We show that this can be explained either by significantly different halo occupation distributions or statistically different host halo assembly histories. Lastly, we see that massive black holes are slightly more likely to reside in central galaxies than black holes of smaller mass.

Differences in eighth grade science student and teacher perceptions of students' level of input into academic planning and decision making

Chapman, Jarrett Michael

Teachers are expected to improve their planning, instruction, and assessment as they progress through their career. An important component to teachers knowing what to modify in their teaching style is being able to solicit meaningful feedback from students. This mixed-methods study was conducted to provide teachers with a quantitative method to collect data about their teaching using the Constructivist Learning Environment Survey (CLES). Phase 1 allowed students to provide anonymous feedback to their teachers that the teachers could later reflect upon in conjunction with the students' other feedback. Using measures of central tendencies, it was determined that of the five categories of the CLES the area of student negotiation was statistically different from the other categories. While eight teachers had sufficient (n>10) student data to be invited to participate in Phase 2, only five of the teachers choose to participate in a semi-structured interview to further examine the potential differences between teacher and student perception of student negotiation with the curriculum, instruction and assessment that occurs in the classroom. Coding the interview transcripts led to three categories: 1) teaching style (with themes including curriculum, instruction, and assessment, and sub themes of teacher centered and student centered); 2) external pressures (with themes of standards , standardized tests, and socioeconomic conditions); 3) effectiveness of student negotiation (with themes of positive effect or no effect on motivation). The five teachers who participated in Phase 2 had varying levels of awareness and willingness to adjust their classroom curriculum, instruction, and assessment to include student negotiation. All but one teacher, however, saw the value in increasing student negotiation in the classroom and desired to continue to change their teaching to include more student negotiation.

THE INFLUENCE OF ENVIRONMENT ON THE CIRCUMGALACTIC MEDIUM

The effect of environment on the circumgalactic medium (CGM) is investigated through a comparison of Lyα absorption line data in the Virgo Cluster and the field. This Letter uses the first systematic survey of background QSOs in and around the Virgo Cluster and large existing surveys of galaxies at low redshift. While previous studies found denser gas (higher equivalent width) closer to a galaxy (lower impact parameter), this correlation disappears in the Virgo environment. In addition, the covering fraction of the CGM is lower in the cluster environment than in the circumcluster environment and field. The results indicate that the CGM is suppressed for cluster galaxies while galaxies in the circumcluster environment have abundant CGM. The truncation of the CGM may result in the quenching of star formation through starvation. Our results also show that CGM surveys must consider the role of environment

To develop an observational instrument that describes the ability of physical environments of institutional settings to address therapeutic goals for persons with dementia. A National Institute on Aging workgroup identified and subsequently revised items that evaluated exit control, maintenance, cleanliness, safety, orientation/cueing, privacy, unit autonomy, outdoor access, lighting, noise, visual/tactile stimulation, space/seating, and familiarity/homelikeness. The final instrument contains 84 discrete items and one global rating. A summary scale, the Special Care Unit Environmental Quality Scale (SCUEQS), consists of 18 items. Lighting items were validated using portable light meters. Concurrent criterion validation compared SCUEQS scores with the Professional Environmental Assessment Protocol (PEAP). Interrater kappa statistics for 74% of items were above.60. For another 10% of items, kappas could not be calculated due to empty cells, but interrater agreement was above 80%. The SCUEQS demonstrated an interrater reliability of.93, a test--retest reliability of.88, and an internal consistency of.81--.83. Light meter ratings correlated significantly with the Therapeutic Environment Screening Survey for Nursing Homes (TESS-NH) lighting items (r =.29--.38, p =.01--.04), and the SCUEQS correlated significantly with global PEAP ratings (r =.52, p TESS-NH efficiently assesses discrete elements of the physical environment and has strong reliability and validity. The SCUEQS provides a quantitative measure of environmental quality in institutional settings.

Fundamental data were gathered for a tree-planting program by surveying photometrically the growth state of plants in relation to topography in Suginami Ward, where the living environment is drastically changing. The photographs taken for the purpose were natural color 1972, infrared color 1972, panchromatic 1963 and 1966, panchromatio-infrachromatic 1970, and infrared 1971. The methods of evaluating tree vigor is explained. The tree species investigated were pasania, zelkova, ginkgo, Himalayan cedar, cherry, and pine. The results were summarized in a tree-vigor map. Vigor was in the descending order of ginkgo, Himalayan cedar, pasania, pine, zelkova and cherry. Along railroads and main roads, vigor was lower.

Exploring associations between perceived home and work neighborhood environments, diet behaviors, and obesity: Results from a survey of employed adults in Missouri

Full Text Available Dietary behaviors are associated with obesity, and may be influenced by the environment. The objective of the current work was to investigate whether perceptions of built environment factors related to eating in the residential neighborhood will have different, independent associations with BMI and dietary behaviors than perceived built environment factors in the worksite neighborhood. In 2012–2013, a cross-sectional telephone-survey of Missouri adults (n = 2015 assessed perceptions of home and workplace built environment factors related to eating, dietary behaviors, and height and weight. Logistic regression models explored associations between perceived neighborhood built environment variables, diet, and obesity. The only variable associated with any of the outcomes explored in the fully adjusted models was the home neighborhood composite scale. None of the work environment variables were significantly associated with any of the health/behavior outcomes after adjustment. Few associations were found after adjustment for personal and job-related characteristics, and none were identified with the workplace neighborhood environment. While few home environment associations were found after adjustment, and none were identified with the perceived workplace neighborhood environment, the current study adds to the limited literature looking at associations between the perceived neighborhood around the workplace neighborhood and the perceived neighborhood around the home and dietary behaviors and obesity in adults. Future studies are needed to determine whether relationships between these environments and behavior exist, and if so, if they are causal and warrant intervention attempts.

Demographic change has resulted in an increase of elderly people, while at the same time the number of active working people is falling. In the future, there will be less caretaking, which is necessary to support the aging population. In order to enable the aged population to live in dignity, they should be able to perform activities of daily living (ADLs) as independently as possible. The aim of this paper is to describe several solutions and concepts that can support elderly people in their ADLs in a way that allows them to stay self-sufficient for as long as possible. To reach this goal, the Building Realization and Robotics Lab is researching in the field of ambient assisted living. The idea is to implement robots and sensors in the home environment so as to efficiently support the inhabitants in their ADLs and eventually increase their independence. Through embedding vital sensors into furniture and using ICT technologies, the health status of elderly people can be remotely evaluated by a physician or family members. By investigating ergonomic aspects specific to elderly people (e.g. via an age-simulation suit), it is possible to develop and test new concepts and novel applications, which will offer innovative solutions. Via the introduction of mechatronics and robotics, the home environment can be made able to seamlessly interact with the inhabitant through gestures, vocal commands, and visual recognition algorithms. Meanwhile, several solutions have been developed that address how to build a smart home environment in order to create an ambient assisted environment. This article describes how these concepts were developed. The approach for each concept, proposed in this article, was performed as follows: (1) research of needs, (2) creating definitions of requirements, (3) identification of necessary technology and processes, (4) building initial concepts, (5) experiments in a real environment, and (6) development of the final concepts. To keep these concepts

Very few studies focus on childhood abuse in developing countries and only a small fraction of such studies explicitly deal with abuse in a school environment. The purpose of this study was to estimate the prevalence of sexual, physical, and emotional abuse in a school environment in a developing country. Abuse history was collected using the International Society for the Prevention of Child Abuse and Neglect (ISPCAN) Child Abuse Screening Tool - Children's Institutional Version (ICAST-CI). Demographic variables were also collected. Student supportive measures were provided both during and after the survey. 6682 school attending adolescents in Thrissur, Kerala participated in this cross sectional self report study. One year and lifetime prevalence of physical (75.5%, 78.5%), emotional (84.5%, 85.7%) and sexual (21.0%, 23.8%) abuse was high. Abuse was considered to be present even if an individual item from these three categories was reported. Most abuse was reported as occurring 'sometimes' rather than 'many times'. More males than females reported being victims of abuse; figures for one-year prevalence were: physical abuse (83.4% vs. 61.7%), emotional abuse (89.5% vs. 75.7%), and sexual abuse (29.5% vs. 6.2%). Various factors significantly increase the likelihood of abuse-male gender, low socioeconomic status, regular use of alcohol and drugs by family member at home, and having other difficulties at school. Children tended to report abuse less frequently if they liked attending school and if they always felt safe at school. The results highlight the urgent need to address the issue of abuse in the school environment and minimize its impact. Copyright © 2017 Elsevier Ltd. All rights reserved.

Student satisfaction is an important element of the effectiveness of clinical placement, but there is little consensus in the literature as to the preferred model of clinical experience for undergraduate nursing students. The aim of this study was assess, for each academic year, students' perception of the roles of nurse teachers (NT) and clinical nurse supervisors (CNS) who perform tutoring in both apprenticeship and laboratories and to identify and evaluate students' satisfaction with the environment of clinical learning. This analytic cross-sectional study was conducted in a sample of 173 nursing students in the Northern Italy. The research instrument used is the Clinical learning environment, supervision and nurse teacher (CLES+T) evaluation scale. Data were statistically analysed. 94% of our sample answered questionnaires. Students expressed a higher level of satisfaction with their training experiences. The highest mean value was in the sub-dimension "Pedagogical atmosphere on the ward". Third year students expressed higher satisfaction levels in their relationship with the CNS and lower satisfaction levels in their relationship with the NT. This result may be due to the educational model that is adopted in the course, in which the simulation laboratory didactic activities of the third year are conducted by CNS, who also supervises experiences of clinical learning in the clinical practice. The main finding in this study was that the students' satisfaction with the supervisory relationship and the role of NT depend on how supervision in the clinical practice and in the simulation laboratory is organized.

The creation of a pedagogy of promise: Examples of educational excellence in high-stakes science classrooms

Science.gov (United States)

McCollough, Cherie A.

The current reform movement in education has two forces that appear contradictory in nature. The first is an emphasis on rigor and accountability that is assessed through high-stakes testing. The second is the recommendation to have student centered approaches to teaching and learning, especially those that emphasize inquiry methodology and constructivist pedagogy. Literature reports that current reform efforts involving accountability through high-stakes tests are detrimental to student learning and are contradictory to student-centered teaching approaches. However, by focusing attention on those teachers who "teach against the grain" and raise the achievement levels of students from diverse backgrounds, instructional strategies and personal characteristics of exemplary teachers can be identified. This mixed-methods research study investigated four exemplary urban high school science teachers in high-stakes (TAKS) tested science classrooms. Classroom observations, teacher and student interviews, pre-/postcontent tests and the Constructivist Learning Environment Survey (CLES) (Johnson & McClure, 2004) provided the main data sources. The How People Learn (National Research Council, 2000) theoretical framework provided evidence of elements of inquiry-based, student-centered teaching. Descriptive case analysis (Yin, 1994) and quantitative analysis of pre/post tests and the CLES revealed the following results. First, all participating teachers included elements of learner-centeredness, knowledge-centeredness, assessment-centeredness and community-centeredness in their teaching as recommended by the National Research Council, (2000), thus creating student-centered classroom environments. Second, by establishing a climate of caring where students felt supported and motivated to learn, teachers managed tensions resulting from the incorporation of student-centered elements and the accountability-based instructional mandates outlined by their school district and state

Curriculum reforms in medical schools require cultural and conceptual changes from the faculty. We assessed attitudes towards curriculum reforms in different academic, economic, and social environments among 776 teachers from 2 Western European medical schools (Belgium and Denmark) and 7 medical...... schools in 3 countries in post-communist transition (Croatia, Slovenia, Bosnia and Herzegovina). The survey included a 5-point Likert-type scale on attitudes towards reforms in general and towards reforms of medical curriculum (10 items each). Teaching staff from medical schools in Bosnia and Herzegovina...... had more positive attitude towards reforms of medical curriculum (mean score 36.8 out of maximum 50 [95% CI 36.1 to 37.3]) than those from medical schools in Croatia or Slovenia (30.7 [29.8 to 31.6]) or Western Europe (27.7 [27.1 to 28.3]) (Pattitudes...

Full Text Available Purpose: While a strong learning environment is critical to medical student education, the assessment of medical school learning environments has confounded researchers. Our goal was to assess the validity and utility of the Johns Hopkins Learning Environment Scale (JHLES for preclinical students at three Malaysian medical schools with distinct educational and institutional models. Two schools were new international partnerships, and the third was school leaver program established without international partnership. Methods: First- and second-year students responded anonymously to surveys at the end of the academic year. The surveys included the JHLES, a 28-item survey using five-point Likert scale response options, the Dundee Ready Educational Environment Measure (DREEM, the most widely used method to assess learning environments internationally, a personal growth scale, and single-item global learning environment assessment variables. Results: The overall response rate was 369/429 (86%. After adjusting for the medical school year, gender, and ethnicity of the respondents, the JHLES detected differences across institutions in four out of seven domains (57%, with each school having a unique domain profile. The DREEM detected differences in one out of five categories (20%. The JHLES was more strongly correlated than the DREEM to two thirds of the single-item variables and the personal growth scale. The JHLES showed high internal reliability for the total score (α=0.92 and the seven domains (α, 0.56-0.85. Conclusion: The JHLES detected variation between learning environment domains across three educational settings, thereby creating unique learning environment profiles. Interpretation of these profiles may allow schools to understand how they are currently supporting trainees and identify areas needing attention.

Full Text Available Stray cats routinely enter animal welfare organizations each year and shelters are challenged with determining the level of human socialization these cats may possess as quickly as possible. However, there is currently no standard process to guide this determination. This study describes the development and validation of a caregiver survey designed to be filled out by a cat’s caregiver so it accurately describes a cat’s personality, background, and full range of behavior with people when in its normal environment. The results from this survey provided the basis for a socialization score that ranged from unsocialized to well socialized with people. The quality of the survey was evaluated based on inter-rater and test-retest reliability and internal consistency and estimates of construct and criterion validity. In general, our results showed moderate to high levels of inter-rater (median of 0.803, range 0.211–0.957 and test-retest agreement (median 0.92, range 0.211–0.999. Cronbach’s alpha showed high internal consistency (0.962. Estimates of validity did not highlight any major shortcomings. This survey will be used to develop and validate an effective assessment process that accurately differentiates cats by their socialization levels towards humans based on direct observation of cats’ behavior in an animal shelter.

2014-07-01

The French Institute for Radioprotection and Nuclear Safety (IRSN) runs a continuous monitoring program of the marine environment as a mandatory task. For the French Mediterranean coast, this monitoring activity focuses on two bio-indicators species: the Mediterranean mussel (Mytilus galloprovincialis) and the red mullet (Mullus sp.) sampled on a regular basis from natural populations at ten locations along the coast. Radionuclides are measured using direct low-level gamma spectrometry as a routine technique. In addition to this long-lasting monitoring, a broad survey of radionuclide baseline levels is conducted on all compartments of the coastal zone: water, sediments and a large selection of fish species among those most currently fished and marketed. This extended data collection is necessary to fulfill the information requirements of the UE Marine Strategy Framework Directive (MSFD) and its implementation by member states. This information is also essential for impact assessment of any incident or accident, included from a remote source. Levels of less commonly measured radionuclides like {sup 3}H, {sup 14}C, {sup 90}Sr, {sup 210}Po and U, Pu isotopes are investigated. Fish sampling relies mostly on scientific stock assessment campaigns. Mussel sampling is complemented by transplanted mussels on 40 specific sites. This regional survey also focuses on two possibly impacted areas: the Rhone river mouth coastal zone, with inputs from nuclear power plants along the river and the Bay of Toulon sheltering Navy harbor of nuclear-powered sub-marines and aircraft-carrier. First results show that the activity levels of artificial radionuclides are very low for most bio-indicator species, in accordance with previous monitoring trends. {sup 137}Cs is the only artificial radionuclide regularly detected by gamma spectrometry in mussel and fish samples at a level below 1 Bg.kg{sup -1} of dry weight. Values of {sup 3}H (organically bound Tritium) in the same samples lies under

Restaurant meals account for a significant portion of the American diet. Investigating disparities in the restaurant food environment can inform targeted interventions to increase opportunities for healthy eating among those who need them most. To examine neighborhood disparities in restaurant density and the nutrition environment within restaurants among a statewide sample of Wisconsin households. Households (N = 259) were selected from the 2009-2010 Survey of the Health of Wisconsin (SHOW), a population-based survey of Wisconsin adults. Restaurants in the household neighborhood were enumerated and audited using the Nutrition Environment Measures Survey for Restaurants (NEMS-R). Neighborhoods were defined as a 2- and 5-mile street-distance buffer around households in urban and non-urban areas, respectively. Adjusted linear regression models identified independent associations between sociodemographic household characteristics and neighborhood restaurant density and nutrition environment scores. On average, each neighborhood contained approximately 26 restaurants. On average, restaurants obtained 36.1% of the total nutrition environment points. After adjusting for household characteristics, higher restaurant density was associated with both younger and older household average age (P restaurant food environment in Wisconsin neighborhoods varies by age, race, and urbanicity, but offers ample room for improvement across socioeconomic groups and urbanicity levels. Future research must identify policy and environmental interventions to promote healthy eating in all restaurants, especially in young and/or rural neighborhoods in Wisconsin.

Fishery is an important industry in Norway. Compared to other industries the number of occupational accidents is high. Fishers are exposed to a range of unfavourable working conditions, but there is limited research-based knowledge about the interaction between working conditions and health. The aim of the article is to study fishers' 1) work-related exposures and health complaints, 2) sickness absence, 3) subjective perception of health status and 3) level of job satisfaction. Data was gathered through a telephone survey. The survey included questions about exposure, health complaints, health status and job satisfaction. Methods for analysis were descriptive statistics and relative risk (RR). A total of 830 full-time fishers were interviewed. Coastal fishers are more exposed to factors such as climatic (RR = 1.546, 95% confidence interval [CI] 1.311-1.823), ergonomic (RR = 1.539, 95% CI 1.293-1.833) and processing (RR = 2.119, 95% CI 1.847-2.431), compared to other groups of fishers. Coastal fishers are also more likely to experience musculoskeletal problems (RR = 1.623, 95% CI 1.139-2.314), sickness absence (RR = 1.337, 95% CI 1.081-1.655) and to perceive their own health as poor (RR = 2.155, 95% CI 1.119-4.152). Purse sein fishers are less exposed to climatic (RR = 0.777, 95% CI 0.633-0.953), ergonomic (RR = 0.617, 95% CI 0.487-0.783) and processing (RR = 0.292, 95% CI 0.221-0.385) factors and are less likely to experience sickness absence (RR = 0.635, 95% CI 0.479-0.840). In terms of job satisfaction, 99% if our respondents enjoy their work. Norwegian fishers have a high degree of job satisfaction and overall good health. Challenges regarding health complaints and exposures in the working environment were identified. This may be helpful for the industry, showing where measures should be implemented to prevent exposure, illness and sickness absence. Findings may also serve as a basis for future intervention studies aimed at promoting healthy working environments

Described herein are results of the natural environment surveys, carried out in the Shitanotai Region in Yuzawa City, Akita Pref., where Geothermal Development Promotion Survey C is scheduled. On-the-spot surveys, conducted from June to November, covered 3 items of landscape, vegetation and animals. The Shimonotai Region has a number of ponds and swamps, some of which are used as fields for Brasenia shreberi, and wet shield plant communities in places reflecting these environments. The zoological survey results show that moderate to dry deciduous forests of Japanese beeches (Fagus crenata) and Mongolian oaks (Quercus mongolica var. grossesserrata) in this region provide sound habitats for large mammalian wild animals, e.g., moon bears (Selenarctos thibetanus). For birds, there are some areas extracted indicating high possibility of being inhabited by honey buzzards (Pernis ptilorhyncus), which are listed as a near threatened species by the Environment Agency. Geologically, traces of landslide occurrence in the past have been detected widely, indicating need for more detailed investigation for land stability. These surveys have extracted several areas whose natural environments and landscapes are damaged relatively little by geothermal development. (NEDO)

Applications of Wireless Sensor Networks in Marine Environment Monitoring: A Survey

2014-01-01

With the rapid development of society and the economy, an increasing number of human activities have gradually destroyed the marine environment. Marine environment monitoring is a vital problem and has increasingly attracted a great deal of research and development attention. During the past decade, various marine environment monitoring systems have been developed. The traditional marine environment monitoring system using an oceanographic research vessel is expensive and time-consuming and has a low resolution both in time and space. Wireless Sensor Networks (WSNs) have recently been considered as potentially promising alternatives for monitoring marine environments since they have a number of advantages such as unmanned operation, easy deployment, real-time monitoring, and relatively low cost. This paper provides a comprehensive review of the state-of-the-art technologies in the field of marine environment monitoring using wireless sensor networks. It first describes application areas, a common architecture of WSN-based oceanographic monitoring systems, a general architecture of an oceanographic sensor node, sensing parameters and sensors, and wireless communication technologies. Then, it presents a detailed review of some related projects, systems, techniques, approaches and algorithms. It also discusses challenges and opportunities in the research, development, and deployment of wireless sensor networks for marine environment monitoring. PMID:25215942

A survey was conducted of bio-chemical complex harmonized with the global environment for the purpose of constructing the material production process harmonized with the environment by the process fusion between biological conversion and chemical reaction. Palm oil was taken up as renewable raw material plant resource. The process utilizing bio-chemical reaction advances at normal temperature and pressure and is high in reaction specificity and selectivity. This is a recycling, circulation and environmental harmony type production technology which brings high yield, energy conservation, resource conservation, and low environmental loads. Waste water treatment and production of useful substances from sludge were thought as elementary technology. A possibility was studied of enzyme production by culturing solid waste, and the enzyme was applied to the hydrolysis process. The paper indicated trace components in the palm oil and the extraction method and proposed the production process of new derivatives for adding value to hydrolysate. A study was also made of the overall process flow which integrated these new processes and the material balance. The comprehensive evaluation of this new process was made from the aspect of the product structure, the market, construction cost, economical efficiency, and the environment. 133 refs., 65 figs., 56 tabs.

Institutional Level Identity Control Strategies in the Distance Education Environment: A Survey of Administrative Staff

Full Text Available Physical separation of students and instructors creates the gap of anonymity and limited control over the remote learning environment. The ability of academic institutions to authenticate students and validate authorship of academic work at various points during a course is necessary for preserving not only perceived credibility but also public safety. With the growing scope of distance education programs that permeate critical areas such as healthcare, airspace, water management, and food solutions, universities have a moral obligation to employ secure measures to verify learning outcomes. This study examines the measures universities with large distance education programs employ to align identity of learners with the academic work they do, as well as the effectiveness of and challenges and barriers to their implementation. The research was undertaken using a multiple case approach and examined survey responses from five academic administrators at five officially accredited post secondary institutions in three countries. The cases examined in the study include: Athabasca University, Open University UK, Penn State University World Campus, University of Maryland University College, and eConcordia, Concordia University’s distance learning facility. This study is not an exhaustive attempt to examine all aspects of academic integrity, but rather to create awareness about various learner authentication strategies. This study confirms that secure learner authentication in the distance education environment is possible. However, with greater pressure to enhance security of learner authentication, the openness of open learning is challenged and may change as we know it.

Background: Modern contraceptive prevalence was 14.1% in 2007 in Kinshasa, the capital city of the Democratic Republic of the Congo (DRC). Yet virtually nothing was known about the family planning supply environment. Methods: Three surveys of health facilities were conducted in 2012, 2013, and 2014 to determine the number, spatial distribution, and attributes of sites providing family planning services. The 2012 and 2013 surveys aimed to identify the universe of family planning facilities while obtaining a limited set of data on “readiness” to provide family planning services (defined as having at least 3 modern methods, at least 1 person training in family planning in the last 3 years, and an information system to track distribution of products to clients) and output (measured by couple-years of protection, or CYP). In contrast, the 2014 survey, conducted under the umbrella of the Performance Monitoring and Accountability 2020 (PMA2020) project, was based on 2-stage cluster sampling. This article provides detailed analysis of the 2012 and 2013 surveys, including bivariate and multivariate analysis of correlates of readiness to provide services and of output. Results: We identified 184 health facilities that reported providing at least 1 contraceptive method in 2012 and 395 facilities in 2013. The percentage of sites defined as “ready” to provide services increased from 44.1% in 2012 to 63.3% in 2013. For the 3-month period between January and March 2013, facilities distributed between 0 and 879.2 CYP (mean, 39.7). Nearly half (49%) of the CYP was attributable to implants, followed by IUDs (24%), CycleBeads (11%), and injectables (8%). In 2013, facilities supported by PEPFAR (n = 121) were more likely than other facilities to be rated as ready to provide services (Pplanning implementing agencies (Pplanning in the DRC in many ways, including mobilizing partners to increase contraceptive access and increasing donor investment in family planning in the DRC

This paper presents a study of the environments of SDSS quasi-stellar objects (QSOs) in the Spitzer Extragalactic Representative Volume Survey (SERVS). We concentrate on the high-redshift QSOs as these have not been studied in large numbers with data of this depth before. We use the IRAC 3.6-4.5 μm color of objects and ancillary r-band data to filter out as much foreground contamination as possible. This technique allows us to find a significant (>4σ) overdensity of galaxies around QSOs in a redshift bin centered on z ∼ 2.0 and an (>2σ) overdensity of galaxies around QSOs in a redshift bin centered on z ∼ 3.3. We compare our findings to the predictions of a semi-analytic galaxy formation model, based on the ΛCDM MILLENNIUM simulation, and find for both redshift bins that the model predictions match well the source density we have measured from the SERVS data.

A survey is conducted of the feasibility of soil environment remediation through detecting contamination of soil and changes in ecosystems caused by industrial activities, with attention paid to biological antagonists. In this fiscal year, based on the results of surveys conducted in the past, studies are continued mainly on hypersensitive biosensing technology using ecosystem functions, remote sensing technology to monitor the terrestrial vegetation and soil environment over wide areas, and soil environment remediation technology using biological antagonists and vegetation. In consideration of Europe's long experience in this field, seven organizations known for their accomplishments are visited, where interviews are held. There is a close relationship between soil environments and ecosystems, and ecosystems are provided not only with information on changes in soil environments but also with functions to remedy soil environments by minimizing secondary contamination.

A survey is conducted of the feasibility of soil environment remediation through detecting contamination of soil and changes in ecosystems caused by industrial activities, with attention paid to biological antagonists. In this fiscal year, based on the results of surveys conducted in the past, studies are continued mainly on hypersensitive biosensing technology using ecosystem functions, remote sensing technology to monitor the terrestrial vegetation and soil environment over wide areas, and soil environment remediation technology using biological antagonists and vegetation. In consideration of Europe's long experience in this field, seven organizations known for their accomplishments are visited, where interviews are held. There is a close relationship between soil environments and ecosystems, and ecosystems are provided not only with information on changes in soil environments but also with functions to remedy soil environments by minimizing secondary contamination. To put such information and functions to practical use, element technologies are indispensable, including hypersensitive soil environment biosensors and environmental remediation by identification and isolation of biological information carrying substances and by vegetation. Proposed in this report is a project for soil remediation by use of biological information and functions and for elucidation of biological antagonists. (NEDO)

Plastic debris, specifically microplastic in the aquatic environment, is an escalating environmental crisis. Efforts at national scales to reduce or ban microplastics in personal care products are starting to pay off, but this will not affect those materials already in the environment or those that result from unregulated products and materials. To better inform future microplastic research and mitigation efforts this study (1) evaluates methods currently used to quantify microplastics in the environment and (2) characterizes the concentration and size distribution of microplastics in a variety of products. In this study, 50 published aquatic surveys were reviewed and they demonstrated that most ( 80%) only account for plastics ≥ 300 μm in diameter. In addition, we surveyed 770 personal care products to determine the occurrence, concentration and size distribution of polyethylene microbeads. Particle concentrations ranged from 1.9 to 71.9 mg g-1 of product or 1649 to 31,266 particles g-1 of product. The large majority ( > 95%) of particles in products surveyed were less than the 300 μm minimum diameter, indicating that previous environmental surveys could be underestimating microplastic contamination. To account for smaller particles as well as microfibers from synthetic textiles, we strongly recommend that future surveys consider methods that materials < 300 μm in diameter.

The IRAS survey reveals a class of ultraluminous infrared (IR) galaxies (ULIRG's) with IR luminosities comparable to the bolometric luminosities of quasars. The nature, origin, and evolution of ULIRG's are attracting more and more attention recently. Since galaxy morphology is certainly a function of environment, morphological observations show that ULIRG's are interacting/merging galaxies, and some ULIRG's might be the dust-enshrouded quasars (S88) or giant ellipticals, the study of ULIRG's environment and large scale clustering effects should be worthwhile. ULIRG's and very luminous IR galaxies have been selected from the 2Jy IRAS redshift survey. Meanwhile, a catalog of IRAS groups of galaxies has been constructed using a percolation-like algorithm. Therefore, whether ULIRG's and/or VLIRG's have a group environment can be checked immediately. Other aspects of the survey are discussed.

Nursing education is a process that includes theoretical and practical learning and requires the acquisition of theoretical knowledge and skill. Nursing students need a good clinical practice environment in order to apply their knowledge and skills due to the fact that the clinical practice settings play an important role in the nursing profession. This study was carried out in an effort to explore nursing students' perception of the clinical learning environment and its association with academic motivation and clinical decision making. A descriptive survey design was used. This study was conducted in Giresun University in Turkey. Participants were second-, third- and fourth-year undergraduate students (n=222) in the Bachelor of Nursing Science Degree in the academic spring term of 2014-2015. The data was collected using the 'Clinical Learning Environment Scale', the 'Academic Motivation, and the 'The Clinical Decision Making in Nursing Scale'. Of the respondents in this study, 45% of the students were second class, 30.6% of the students were third class and 24.3% of the students were fourth class. There was a statistically significant positive correlation found between the clinical learning environment and the nursing students' academic motivation (r=0.182, pdecision making (r=0.082, p>.05). One of the prerequisites for the training of qualified students is to provide nursing students with a qualified clinical environment. It was found that nursing students' academic motivation increased as the quality of their clinical learning environment improved. Copyright © 2015 Elsevier Ltd. All rights reserved.

This article reports the results of color and psychological analysis of the outlook of nuclear power plants and the visual environments inside of the plants. Study one was the color measurements of the outlook of nuclear plants and the visual environment inside of the plants. Study two was a survey of the impressions on the visual environments of nuclear plants obtained from observers and interviews of the workers. Through these analysis, we have identified the present state of, and the problems of the color environments of the nuclear plants. In the next step, we have designed the color environments of inside and outside of the nuclear plants which we would recommend (inside designs were about fuel handling room, operation floor of turbine building, observers' pathways, central control room, rest room for the operators). Study three was the survey about impressions on our design inside and outside of the nuclear plants. Nuclear plant observers, residents in Osaka city, residents near the nuclear plants, the operators, employees of subsidiary company and the PR center guides rated their impressions on the designs. Study four was the survey about the design of the rest room for the operators controlling the plants. From the results of four studies, we have proposed some guidelines and problems about the future planning about the visual environments of nuclear power plants. (author)

To overcome the technological and economic obstacles of amorphous indium-gallium-zinc-oxide (a-IGZO)-based display backplane for industrial production, a clean etch-stopper (CL-ES) process is developed to fabricate a-IGZO-based thin film transistor (TFT) with improved uniformity and reproducibility on 8.5th generation glass substrates (2200 mm × 2500 mm). Compared with a-IGZO-based TFT with back-channel-etched (BCE) structure, a newly formed ES nano-layer ( 100 nm) and a simultaneous etching of a-IGZO nano-layer (30 nm) and source-drain electrode layer are firstly introduced to a-IGZO-based TFT device with CL-ES structure to improve the uniformity and stability of device for large-area display. The saturation electron mobility of 8.05 cm2/V s and the V th uniformity of 0.72 V are realized on the a-IGZO-based TFT device with CL-ES structure. In the negative bias temperature illumination stress and positive bias thermal stress reliability testing under a ± 30 V bias for 3600 s, the measured V th shift of CL-ES-structured device significantly decreased to - 0.51 and + 1.94 V, which are much lower than that of BCE-structured device (- 3.88 V, + 5.58 V). The electrical performance of the a-IGZO-based TFT device with CL-ES structure implies that the economic transfer from a silicon-based TFT process to the metal oxide semiconductor-based process for LCD fabrication is highly feasible.

With estimates of a 51% growth in the number of nursing assistants needed by 2016, there is a critical need to examine workplace factors that negatively contribute to the recruitment and retention of nursing assistants. Studies have shown that high demands, physical stress, and chronic workforce shortages contribute to a working environment that fosters one of the highest workforce injury rates in the United States. The aim of this study was to explore the relationship between nursing assistant injury rates and key outcomes, such as job satisfaction and turnover intent, while exploring workplace environment factors, such as injury prevention training, supervisor support, and employee engagement, that can decrease the rates of workplace injury. Data from the 2004 National Nursing Assistant Survey were used to examine the negative effects of workplace injury on nursing assistants and the workplace environment factors that are related to the rate of worker injury. Nursing assistants who experience job-related injuries have lower levels of job satisfaction, increased turnover intentions, and are less likely to recommend their facility as a place to work or seek care services. It was also found that nursing assistant injury rates are related to employee ratings of injury prevention training, supervisor support, and employee engagement. NAs with multiple injuries (>2) were 1.3-1.6 times more likely to report being injured at work than NAs who had not been injured when supervisor support, employee engagement, and training ratings were low. Evidence that health care organizations can use to better understand how workplace injuries occur and insight into ways to reduce the current staggering rate of on-the-job injuries occurring in health care workplaces were offered in this study. The findings also offer empirical support for an extension of the National Institute for Occupational Health and Safety/National Occupational Research Agenda Work Organization Framework for

In the period from April 1999 to May 2000, organotin pollution, namely butyl and phenyltins, was investigated in coastal and continental waters (46 stations), estuarine sediments (15 stations) and mussels (Mytilus galloprovincialis) (13 stations) throughout Portugal. Sampling points were chosen in areas of specific industrial, agricultural and harbor activities. Butyltins (BTs) were the only tin species identified of which tributyltin (TBT) was found in the whole area. Concentrations of TBT in river water ranged from 3 to 30 ng L{sup -1} (as Sn), marine sediment ranged from 4 to 12 {mu}g kg{sup -1} (as Sn), whereas concentrations in mussel tissue ranged from 2.5 to 490 {mu}g kg{sup -1} (as Sn). Given that some water samples appeared to be contaminated by higher monobutyltin (MBT) and dibutyltin (DBT) concentrations, the role of biological degradation and direct inputs from agricultural and industrial applications areas are discussed. The study compares depleted butyltin pollution in sediments and mussels of the Portuguese coastline associated with antifouling paints with previously reported levels. Inputs in river waters are more related to (i) PVC leaching and (ii) industrial sources, in some cases discharged by municipal wastewaters. - Survey data illustrate the complexities of organotin sources and cycling in coastal environments.

A survey was performed on the current situation in the Kuwanosawa district in Akita Prefecture to identify influence on the surrounding environment due to drilling of geothermal structure testing wells. The survey on animals covered mammals of five divisions, 10 families and 19 species, Aves of ten divisions, 25 families and 73 species, reptiles of one division, 3 families and 6 species, Amphibia of two divisions, 6 families, 9 species, and Insects of 17 divisions, 179 families and 719 species. Precious animals of a several species including black salamander were identified. In the plant survey, 132 families and 670 species were identified, with several species listed as the precious plants. In the survey of hot springs, those at three locations were all high-temperature hot springs at as high as 53.8 to 96.9 degrees C. Amount of discharge, pH and electrical conductivity differ largely by the hot springs. The hot spring in Takamatsu did not show large variation throughout the survey period. The Ogura Inn at Doroyu Spa has small variation in pH and hot spring temperature, but large variation in the amount of discharge and Al{sup 3+} concentration. Correlation was recognized between hot spring temperature and amount of discharge, between hot spring temperature and anion, between amount of discharge and electric conductivity, and between amount of discharge and anion.

Instruments operating in particle accelerators and colliders are exposed to radiations that are composed of particles of different types and energies. Several of these instruments often embed devices that are not hardened against radiation effects. Thus, there is a strong need for mon- itoring the levels of radiation inside the mixed-field radiation areas, throughout different positions. Different metrics exist for measuring the radiation damage induced to electronic devices, such as the Total Ionizing Dose (TID), the Displacement Damage (DD) and of course the fluence of parti- cles for estimating the error rates of the electronic devices among other applications. In this paper, we propose an SRAM based monitor, that is used to define the fluence of High Energy Hadrons (HEH) by detecting Single Event Upsets in the memory array. We evaluated the device by testing it inside the H4IRRAD area of CERN, a test area that reproduces the radiation conditions inside the Large Hadron Collider (LHC) tunnel and its shield...

Comparison of Satellite Surveying to Traditional Surveying Methods for the Resources Industry

Science.gov (United States)

Osborne, B. P.; Osborne, V. J.; Kruger, M. L.

Modern ground-based survey methods involve detailed survey, which provides three-space co-ordinates for surveyed points, to a high level of accuracy. The instruments are operated by surveyors, who process the raw results to create survey location maps for the subject of the survey. Such surveys are conducted for a location or region and referenced to the earth global co- ordinate system with global positioning system (GPS) positioning. Due to this referencing the survey is only as accurate as the GPS reference system. Satellite survey remote sensing utilise satellite imagery which have been processed using commercial geographic information system software. Three-space co-ordinate maps are generated, with an accuracy determined by the datum position accuracy and optical resolution of the satellite platform.This paper presents a case study, which compares topographic surveying undertaken by traditional survey methods with satellite surveying, for the same location. The purpose of this study is to assess the viability of satellite remote sensing for surveying in the resources industry. The case study involves a topographic survey of a dune field for a prospective mining project area in Pakistan. This site has been surveyed using modern surveying techniques and the results are compared to a satellite survey performed on the same area.Analysis of the results from traditional survey and from the satellite survey involved a comparison of the derived spatial co- ordinates from each method. In addition, comparisons have been made of costs and turnaround time for both methods.The results of this application of remote sensing is of particular interest for survey in areas with remote and extreme environments, weather extremes, political unrest, poor travel links, which are commonly associated with mining projects. Such areas frequently suffer language barriers, poor onsite technical support and resources.

Living in an obesogenic environment may not affect all adolescents to the same extent, depending on their psychological sensitivity to the food environment and their self-regulatory competence. The purpose of the current study was to examine associations of these two factors with unhealthy snacking among adolescents. We also investigated whether self-regulatory competence could attenuate the negative effects of being sensitive to the food environment. A survey was completed by 11,392 European adolescents (10-17years old). The survey measured psychological sensitivity to the food environment, self-regulatory competence and self-reported unhealthy snack intake. Higher food environment sensitivity and lower self-regulatory competence were associated with more unhealthy snacking. The two factors also interacted, with self-regulatory competence attenuating the influence of high food environment sensitivity. Adolescents who are sensitive to the food environment reported higher unhealthy snack intake. More frequent use of self-regulation strategies on the other hand was associated with lower unhealthy snack intake. Moreover, self-regulatory competence was found to moderate the influence of psychological sensitivity to the food environment on unhealthy snacking, although the effect size was small. Fostering adolescents' self-regulatory competence can help enable them to better navigate the obesogenic environment. Copyright © 2014 Elsevier Ltd. All rights reserved.

On September 6, 2013, a near-perfect launch of the first Minotaur V rocket successfully carried NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE) into a high-eccentricity geocentric orbit. LADEE arrived at the Moon on October 6, 2013, dur-ing the government shutdown. The spacecraft impact-ed the lunar surface on April 18, 2014, following a completely successful mission. LADEE's science objectives were twofold: (1) De-termine the composition and variability of the lunar atmosphere; (2) Characterize the lunar exospheric dust environment, and its variability. The LADEE science payload consisted of the Lunar Dust Experiment (LDEX), which sensed dust impacts in situ, for parti-cles between 100 nm and 5 micrometers; a neutral mass spectrometer (NMS), which sampled lunar exo-spheric gases in situ, over the 2-150 Dalton mass range; an ultraviolet/visible spectrometer (UVS) ac-quired spectra of atmospheric emissions and scattered light from tenuous dust, spanning a 250-800 nm wave-length range. UVS also performed dust extinction measurements via a separate solar viewer optic. The following are preliminary results for the lunar exosphere: (1) The helium exosphere of the Moon, first observed during Apollo, is clearly dominated by the delivery of solar wind He++. (2) Neon 20 is clearly seen as an important constituent of the exosphere. (3) Argon 40, also observed during Apollo and arising from interior outgassing, exhibits variations related to surface temperature-driven condensation and release, and is also enhanced over specific selenographic longi-tudes. (4) The sodium abundance varies with both lu-nar phase and with meteoroid influx, implicating both solar wind sputtering and impact vaporization process-es. (5) Potassium was also routinely monitored and exhibits some of the same properties as sodium. (6) Other candidate species were seen by both NMS and UVS, and await confirmation. Dust measurements have revealed a persistent "shroud" of small dust particles

2014-01-01

Critical levels (CLEs) of atmospheric ammonia based on biodiversity changes have been mostly calculated using small-scale single-source approaches, to avoid interference by other factors, which also influence biodiversity. Thus, it is questionable whether these CLEs are valid at larger spatial scales, in a multi- disturbances context. To test so, we sampled lichen diversity and ammonia at 80 sites across a region with a complex land-cover including industrial and urban areas. At a regional scale, confounding factors such as industrial pollutants prevailed, masking the CLEs. We propose and use a new tool to calculate CLEs by stratifying ammonia concentrations into classes, and focusing on the highest diversity values. Based on the significant correlations between ammonia and biodiversity, we found the CLE of ammonia for Mediterranean evergreen woodlands to be 0.69 μg m −3 , below the previously accepted value of 1.9 μg m −3 , and below the currently accepted pan-European CLE of 1.0 μg m −3 . - Highlights: • Biodiversity responds to multiple disturbances. • This prevents calculation regional critical levels of atmospheric ammonia. • We propose a tool to overcome that, based on the maximum biodiversity observed. • Critical level for Mediterranean evergreen woodlands was revised down to 0.69 μg m −3 . - Critical levels of atmospheric ammonia have not been calculated at a regional scale. Using a new method, we revised down the current Mediterranean evergreen woodlands critical level to 0.69 μg m −3

The international youth population has significant unmet health needs, and there have been many calls to increase youth health care access. Community pharmacies may be able to help address these needs, but very little research has investigated this area and it is not known whether the current community pharmacy setting is acceptable or appropriate for youth. 1) To obtain information on physical factors which could affect young people's use of community pharmacies in New Zealand, including accessibility, opening times and the physical youth-friendliness of the pharmacy environment. 2) To involve and utilize young people in the research process, in order to understand their needs and interpretation of survey data. This study applied a cross sectional survey design, informed by a sequential youth participatory approach. A questionnaire was developed in consultation with a youth advisory group (YAG). Questionnaires distributed to pharmacists at 500 randomly selected pharmacies nationwide between May and September 2011 collected information on whether the pharmacy met selected youth-friendly criteria. These included physical aspects of youth-friendliness, such as opening times and the pharmacy environment. The YAG also provided a youth perspective in the interpretation of the results. Three mail shots achieved a response rate of 50.5%. Most respondents reported the pharmacy to be accessible by public transport and many had extended opening hours. Although most pharmacies met some youth-friendly criteria with regards to the pharmacy environment (e.g. having a private consultation area), more specific criteria (such as displaying youth health information) were usually not met. Interpretive feedback from the YAG highlighted areas for improvement. Pharmacies show potential as youth-friendly health care access points and most already meet some youth-friendly criteria. Areas identified for improvement will require a greater youth focus from the profession, and should be

Technology has become a ubiquitous part of our society and is largely embedded in today's educational system. 3D virtual reality technology can be used to simulate environments and activities and may be used as an instructional technology. The purpose of this research was to better understand the utility of a web-based virtual environment as a teaching tool to represent clinical assessment and interventions in the home environment. Specifically, students' learning outcomes related to interprofessional collaboration, patient-centered decision-making, and appreciation of the environmental and social context of functional mobility and occupational performance will be described through descriptive analysis. Thirty-four physical therapist students and 35 occupational therapist students participated in an instructor-guided virtual assessment of a client's function in a home environment utilizing a virtual environment, Second Life®. Teams formulated task-specific, functional client goals and home modification recommendations. Students revisited a solution virtual environment to view and evaluate recommendations in a follow-up instructor-guided tour. Students completed a web-based survey capturing student perception of the experience. Team assignments were analyzed based on a rubric representing learning objectives. Descriptive analysis was conducted on the survey. Assignment analysis revealed contextual and client-centered recommendations. Student surveys revealed that students found the virtual environment supportive of learning. Student surveys and reflection statements were supportive of the interprofessional collaboration. Use of a virtual environment in instruction allows an authentic means of representing interprofessional home assessment. The virtual environment allowed a temporal depiction of home environment issues and solutions providing the unique opportunity for students to evaluate home recommendations.

We develop empirical methods for modeling the galaxy population and populating cosmological N-body simulations with mock galaxies according to the observed properties of galaxies in survey data. We use these techniques to produce a new set of mock catalogs for the DEEP2 Galaxy Redshift Survey based on the output of the high-resolution Bolshoi simulation, as well as two other simulations with different cosmological parameters, all of which we release for public use. The mock-catalog creation technique uses subhalo abundance matching to assign galaxy luminosities to simulated dark-matter halos. It then adds color information to the resulting mock galaxies in a manner that depends on the local galaxy density, in order to reproduce the measured color-environment relation in the data. In the course of constructing the catalogs, we test various models for including scatter in the relation between halo mass and galaxy luminosity, within the abundance-matching framework. We find that there is no constant-scatter model that can simultaneously reproduce both the luminosity function and the autocorrelation function of DEEP2. This result has implications for galaxy-formation theory, and it restricts the range of contexts in which the mock catalogs can be usefully applied. Nevertheless, careful comparisons show that our new mock catalogs accurately reproduce a wide range of the other properties of the DEEP2 catalog, suggesting that they can be used to gain a detailed understanding of various selection effects in DEEP2.

Determine the relationship between walkability scores (using the Walk Score(®)) and activity levels (both bicycle and walking) in adults aged between 70 and 85 years in Rochester, Minnesota. This was a self-reported cross-sectional survey in adults aged over 70 years living in Rochester, Minnesota. Analysis used t-tests or chi-square analysis as appropriate. The primary endpoint was bicycle use or walking. The predictor variables were the Walk Score(®) as determined by their address, Charlson index, Duke Activity Status Index (DASI), and a 12-item short-form survey (SF-12) scores. Secondary analysis used an outcome of functional status (using the DASI) and walkability scores. Fifty-three individuals completed the surveys (48% return rate). The average age in the overall cohort was 77.02 years. Eighty-nine percent of individuals could walk at least a block and 15.1% rode their bicycles. The Walk Scores(®) did not differ between those who walked (38.9 ± 27.4) and those that did not (40.0 ± 36.08; P = 0.93). In a similar fashion, the Walk Scores(®) were not different for those who biked (36.38 ± 27.68) and those that did not (39.44 ± 28.49; P = 0.78). There was no relationship between Walk Scores(®) and DASI; however, a decreased DASI score was associated with increased age and comorbid illness (Charlson Score). In this small pilot survey, there was no difference in Walk Scores(®) between those older adults who walked or biked, compared to those that did not. The Walk Scores(®) were low in both groups, which may indicate the lack of accessibility for all older adults living in Rochester, Minnesota. The functional status seemed to be more related to age or comorbid conditions than the built environment.

Nurse job satisfaction is a complex phenomenon and includes elements of the work environment. The purpose of this study was to evaluate nurses' perception of their real (current) and ideal (preferred) work environment in a pediatric tertiary care setting. Using a descriptive survey design, a convenience sample of staff nurses from three inpatient units was surveyed using the Work Environment Scale (WES) by Moos (1994). The WES consists of 10 subscales characterizing three dimensions: Relationship, Personal Growth, and System Maintenance and Change. Overall, nurses affirmed a highly positive and supportive work environment on their units. Non-significant findings between the real and ideal scores for the Involvement and Managerial Control subscales suggest that staff are concerned about and committed to their work, and satisfied with their managers' use of rules and procedures. Statistically significant differences between selected real and ideal subscale scores will help target intervention strategies to enhance the nursing work environment.

The trends of the ongoing researches on intermetallic compounds are surveyed through interviews and inquiries, in order to evaluate the results of the projects and research and development of the advanced materials for severe environments, and also to survey the research trends. The survey results are pigeonholed into 4 general categories; (1) research trends in the USA, UK and Germany, (2) notable topics of recent progress in intermetallic research and development, (3) evaluation of the projects, and (4) lists of the results of the researches on the Al-Ti and Al-Nb intermetallic compounds. The ongoing projects include those for intermetallic compounds of high specific strength and of high melting point, the former being represented by Al-Ti compounds and the latter by Al-Nb compounds, for aircraft and space development purposes. The projects are evaluated, viewed from materials and purposes/targets pursued by the projects, R and D organizations, and degree of attention the projects are attracting. The intermetallic compounds are extensively studied and attracting attention in various countries, but possibilities of achieving the set targets are rather pessimistic. (NEDO)

To describe nurses' perceptions concerning their professional practice environment in mainland China and identify factors associated with these views. Globally, the environments in which nurses work influence the quality of nursing practice and health care. A cross-sectional descriptive survey using both paper- and online-based delivery modes was used. A convenience sampling method was used. The survey questionnaire was composed of sociodemographic items and the 38-item Chinese version of Professional Practice Environment survey. The content of the paper-based questionnaire was identical to the online survey. Pearson's chi-square test was conducted to compare the demographic characteristics of these two data sets. Descriptive statistics analysis included frequency, percentage, mean and standard deviation. Multiple linear regression analysis using the Backwards method was applied to identify independent predictors of each subscale of the 38-item Chinese version of Professional Practice Environment. A total of 573 questionnaires were analysed. The mean score of each subscale of the 38-item Chinese version of Professional Practice Environment in this study ranged from 2·66-3·05. All subscales except work motivation (3·05, standard deviation: 0·44) scored less than 3·0. Areas rated as most in need of improvement included control over practice, interpersonal interaction, supportive leadership and handling conflict, and staff relationships with physicians and autonomy. This study has identified nurses' perspectives regarding their workplaces in contemporary China. These data have provided an important baseline for developing and implementing culturally appropriate strategies to improve the working environment of Chinese nurses. A supportive and enabling work environment promotes professional development and the safety and quality of health care. Addressing these factors is important in optimising work place environments. © 2015 John Wiley & Sons Ltd.

Health facility service environment is an important factor for newborns survival and well-being in general and in particular in high mortality settings such as Malawi where despite high coverage of essential interventions, neonatal mortality remains high. The aim of this study is to assess whether the quality of the health service environment at birth is associated with quality of care received by the newborn. We used data from the Malawi Millennium Development Goals Endline household survey conducted as part of MICS survey program and Service Provision Assessment Survey carried out in 2014. The analysis is based on 6218 facility births that occurred during the past 2 years. Descriptive statistics, bivariate and multivariate random effect models are used to assess the association of health facility service readiness score for normal deliveries and newborn care with newborns receiving appropriate newborn care, defined for this analysis as receiving 5 out of 6 recommended interventions during the first 2 days after birth. Newborns in districts with top facility service readiness score have 1.5 higher odds of receiving appropriate newborn care (adjusted odds ratio (aOR) = 1.52, 95% confidence interval CI = 1.19-1.95, P  = 0.001), as compared to newborns in districts with a lower facility score after adjusting for potential confounders. Newborns in the Northern region were two times more likely to receive 5 newborn care interventions as compared to newborns in the Southern region (aOR = 2.06, 95% CI = 1.50-2.83, P  < 0.001). Living in urban or rural areas did not have an impact on receiving appropriate newborn care. There is need to increase the level of service readiness across all facilities, so that all newborns irrespective of the health facility, district or region of delivery are able to receive all recommended essential interventions. Investments in health systems in Malawi should concentrate on increasing training and availability of

The EMF Research and Public Information Dissemination Program (RAPID) includes several engineering research in the area of exposure assessment and source characterization. RAPID engineering project No. 3: ''Environmental Field Surveys'' was performed to obtain information on the levels and characteristics of different environments, for which only limited data were available, especially in comparison to magnetic field data for the residential environment and for electric utility facilities, such as power lines and substations. This project was also to provide information on the contribution of various field sources in the surveyed environments. Magnetic field surveys were performed at four sites for each of five environments: schools, hospitals, office buildings, machine shops, and grocery stores. Of the twenty sites surveyed, 11 were located in the San Francisco Bay Area and 9 in Massachusetts. The surveys used a protocol based on magnetic field measurements and observation of activity patterns, designed to provide estimates of magnetic field exposure by type of people and by type of sources. The magnetic field surveys conducted by this project produced a large amount of data which will form a part of the EMF measurement database Field and exposure data were obtained separately for ''area exposure'' and ''at exposure points''. An exposure point is a location where persons engage in fixed, site specific activities near a local source that creates a significant increase in the area field. The area field is produced by ''area sources'', whose location and field distribution is in general not related to the location of the people in the area.

The full extent of hydrocarbon reserves within Canada's Arctic margin is not appreciated at present. With the exception of the southern Beaufort Sea, the crustal structure of most of Canada's offshore polar margin remains a mystery, even at reconnaissance level. Navigation to support offshore Arctic surveys have required a special application and adaptation of the conventional SYLEDIS (SYsteme LEgere de DIStance) range-range navigational system to perform under the northeast Actic margin's environment. Once adapted, the system has proven very effective with a few Arctic environment servicing problems. The total number of locations involved in the earlier surveys ranged from 20 to aproximately 50 per project in a season. The SYLEDIS operation has enabled real-time positioning with a precision of better than 10 metres for approximately 350 separate sites in the 1985 and 1986 surveys inclusive. 2 refs., 3 figs.

To overcome the technological and economic obstacles of amorphous indium-gallium-zinc-oxide (a-IGZO)-based display backplane for industrial production, a clean etch-stopper (CL-ES) process is developed to fabricate a-IGZO-based thin film transistor (TFT) with improved uniformity and reproducibility on 8.5th generation glass substrates (2200 mm × 2500 mm). Compared with a-IGZO-based TFT with back-channel-etched (BCE) structure, a newly formed ES nano-layer (~ 100 nm) and a simultaneous etching of a-IGZO nano-layer (30 nm) and source-drain electrode layer are firstly introduced to a-IGZO-based TFT device with CL-ES structure to improve the uniformity and stability of device for large-area display. The saturation electron mobility of 8.05 cm 2 /V s and the V th uniformity of 0.72 V are realized on the a-IGZO-based TFT device with CL-ES structure. In the negative bias temperature illumination stress and positive bias thermal stress reliability testing under a ± 30 V bias for 3600 s, the measured V th shift of CL-ES-structured device significantly decreased to - 0.51 and + 1.94 V, which are much lower than that of BCE-structured device (- 3.88 V, + 5.58 V). The electrical performance of the a-IGZO-based TFT device with CL-ES structure implies that the economic transfer from a silicon-based TFT process to the metal oxide semiconductor-based process for LCD fabrication is highly feasible.

Narcolepsy is a sleep disorder caused by the loss of orexin (hypocretin)-producing neurons and marked by excessive daytime sleepiness and a sudden weakening of muscle tone, or cataplexy, often triggered by strong emotions. In a mouse model for narcolepsy, we previously demonstrated that serotonin neurons of the dorsal raphe nucleus (DRN) mediate the suppression of cataplexy-like episodes (CLEs) by orexin neurons. Using an optogenetic tool, in this paper we show that the acute activation of DRN serotonin neuron terminals in the amygdala, but not in nuclei involved in regulating rapid eye-movement sleep and atonia, suppressed CLEs. Not only did stimulating serotonin nerve terminals reduce amygdala activity, but the chemogenetic inhibition of the amygdala using designer receptors exclusively activated by designer drugs also drastically decreased CLEs, whereas chemogenetic activation increased them. Moreover, the optogenetic inhibition of serotonin nerve terminals in the amygdala blocked the anticataplectic effects of orexin signaling in DRN serotonin neurons. Taken together, the results suggest that DRN serotonin neurons, as a downstream target of orexin neurons, inhibit cataplexy by reducing the activity of amygdala as a center for emotional processing.

The purpose of this study was to examine associations among the nursing work environment, nurse job satisfaction, and intent to stay for nurses who practice in hospitals in Jordan. A quantitative descriptive cross-sectional survey design was used. Data were collected through survey questionnaires distributed to 650 registered nurses (RNs) who worked in three hospitals in Jordan. The self-report questionnaire consisted of three instruments and demographic questions. The instruments were the Practice Environment Scale of the Nursing Work Index (PES-NWI), the McCain Intent to Stay scale, and Quinn and Shepard's (1974) Global Job Satisfaction survey. Descriptive statistics were calculated for discrete measures of demographic characteristics of the study participants. Multivariate linear regression models were used to explore relationships among the nursing work environment, job satisfaction, and intent to stay, adjusting for unit type. There was a positive association between nurses' job satisfaction and the nursing work environment (t = 6.42, p job satisfaction increased by 1.3 points, controlling for other factors. Overall, nurses employed in public hospitals were more satisfied than those working in teaching hospitals. The nursing work environment was positively associated with nurses' intent to stay (t = 4.83, p job satisfaction. More attention should be paid to create positive work environments to increase job satisfaction for nurses and increase their intent to stay. Hospital and nurse managers and healthcare policymakers urgently need to create satisfactory work environments supporting nursing practice in order to increase nurses' job satisfaction and intent to stay. © 2016 Sigma Theta Tau International.

1988-01-01

Concern about the potential for indoor air pollution has prompted recent surveys of radon and NO 2 concentrations in homes and personal exposure studies of volatile organics, carbon monoxide and pesticides, to name a few. The statistical problems in designing sample surveys that measure the physical environment are diverse and more complicated than those encountered in traditional surveys of human attitudes and attributes. This paper addresses issues encountered when designing indoor air quality (IAQ) studies. General statistical concepts related to target population definition, frame creation, and sample selection for area household surveys and telephone surveys are presented. The implications of different measurement approaches are discussed, and response rate considerations are described

2014-10-01

After an exposition of the materials used in DPCs and the factors controlling material corrosion in disposal environments, a survey is given of the corrosion rates, mechanisms, and products for commonly used stainless steels. Research needs are then identified for predicting stability of DPC materials in disposal environments. Stainless steel corrosion rates may be low enough to sustain DPC basket structural integrity for performance periods of as long as 10,000 years, especially in reducing conditions. Uncertainties include basket component design, disposal environment conditions, and the in-package chemical environment including any localized effects from radiolysis. Prospective disposal overpack materials exist for most disposal environments, including both corrosion allowance and corrosion resistant materials. Whereas the behavior of corrosion allowance materials is understood for a wide range of corrosion environments, demonstrating corrosion resistance could be more technically challenging and require environment-specific testing. A preliminary screening of the existing inventory of DPCs and other types of canisters is described, according to the type of closure, whether they can be readily transported, and what types of materials are used in basket construction.

Full Text Available Dans la « Quatrième partie » de l’Histoire d’Espagne (1270, on ne trouve nulle évocation du statut intermédiaire qu’avaient pu avoir, jusqu’au XIIe siècle, ces seigneures d’infantat, vouées à la chasteté et au célibat mais non recluses, ce qui leur permettait de participer pleinement à la vie politique du royaume. À travers l’image d’Urraque, d’Elvire et de Sancie, on perçoit surtout le rôle que jouèrent les femmes auprès d’Alphonse X et de ses successeurs. La Chronique de vingt rois (1282-1284 semble témoigner du soutien que le roi Sage avait pu trouver auprès de ses filles à la fin de son règne. Profondément influencées par la reine et régente Marie de Molina, la Version sancienne (1289 et la Chronique de Castille (1295-1312 laissent entrevoir les orientations du programme politique « molinien ».

The National Asthma Survey--New York State (NYS), a telephone survey of NYS residents, was conducted in 2002-2003 to further understand the burden of asthma among adults and children and to identify health, socioeconomic, behavioral, and environmental factors associated with asthma. A total of 1,412 households with at least one member with current asthma and 2,290 control households answered questions about their home environment (e.g., presence of asthma triggers and practices that promote or reduce common asthma triggers). RESULTS; For children younger than 18 years of age, we found statistically significant positive associations between current asthma and the presence of mold (adjusted odds ratio [AOR] = 2.1, 95% confidence interval [CI] 1.3, 3.3), air cleaners (AOR = 1.5, 95% CI 1.1, 2.1), dehumidifiers (AOR = 2.0, 95% CI 1.4, 2.7), and humidifiers (AOR = 1.6, 95% CI 1.1, 2.3). For adults, there were statistically significant positive associations with the presence of mold (AOR = 2.5, 95% CI 1.8, 3.4), air cleaners (AOR = 2.2, 95% CI 1.7, 2.8), and humidifiers (AOR = 1.4, 95% CI 1.1, 1.8). There were no statistically significant associations with the presence of cockroaches, pets, or tobacco smoke, while use of a wood-burning stove or fireplace was significantly more prevalent in control homes. Asthma guidelines emphasize the importance of reducing triggers in the home as part of a multifaceted approach to asthma control. Despite these guidelines, many asthma triggers (specifically, mold) were as prevalent or more so in the homes of New Yorkers with asthma as compared with control households. Public health interventions in NYS should focus on educating households about potential asthma triggers and their sources and teach methods to prevent, reduce, or eliminate them.

Neighborhood-level characteristics such as economic hardship and the retail food environment are assumed to be correlated and to influence consumers' dietary behavior and health status, but few studies have investigated these different relationships comprehensively in a single study. This work aims to investigate the association between neighborhood-level economic hardship, the retail food environment, fast food consumption, and obesity prevalence. Linking data from the population-based Survey of the Health of Wisconsin (SHOW, n = 1,570, 2008-10) and a commercially available business database, the Wisconsin Retail Food Environment Index (WRFEI) was defined as the mean distance from each participating household to the three closest supermarkets divided by the mean distance to the three closest convenience stores or fast food restaurants. Based on US census data, neighborhood-level economic hardship was defined by the Economic Hardship Index (EHI). Relationships were analyzed using multivariate linear and logistic regression models. SHOW residents living in neighborhoods with the highest economic hardship faced a less favorable retail food environment (WRFEI = 2.53) than residents from neighborhoods with the lowest economic hardship (WRFEI = 1.77; p-trend associations between the WRFEI and obesity and only a weak borderline-significant association between access to fast food restaurants and self-reported fast food consumption (≥ 2 times/week, OR = 0.59-0.62, p = 0.05-0.09) in urban residents. Participants reporting higher frequency of fast food consumption (≥ 2 times vs. obese (OR = 1.35, p = 0.06). This study indicates that neighborhood-level economic hardship is associated with an unfavorable retail food environment. However inconsistent or non-significant relationships between the retail food environment, fast food consumption, and obesity were observed. More research is needed to enhance methodological approaches to assess the retail food environment and

It is very important in the site characterization for the HLW disposal to understand changes in geochemical performances caused by volcanic activities in the groundwater environment as the natural barrier. The various effects and its magnitude of changes were listed up and were filed from literature surveys of the correlation between volcanic activities and hydrological can geochemical changes (e.g. water temperature, water pressure, water level, dissolved gas concentration of He and Rn, isotopic ratio of He, and chloride concentration) in volcanic aquifer. However, it is difficult to evaluate the magnitude of impacts, which volcanic activities will give to the groundwater environment in the natural barrier, through only the literature surveys. We have started monitoring of groundwater level and changes in groundwater quality, since volcanic activities have enhanced at Mt. Iwate from June in 1998. Judging from variation of isotopic ratio of dissolved He in groundwater, a prompt and sharp signals indicating volcanic activities will easily be found in shallow groundwater and discharged ponds. On the other hands, geochemical conditions in deep groundwater surroundings from some 100 m to 1000 m deep will be very stable, if the area being more than 5 km apart from the volcanic active center. Consequently, our observed results suggest that the groundwater environment which is not directly disturbed by the underground magmatic activities spreads under the area that is connected to trench side of the volcanic front.

Radioecology: nuclear energy and the environment

International Nuclear Information System (INIS)

Whicker, F.W.; Schultz, V.

1982-01-01

Radioecology is the field of study in which elements of physical and biological sciences are combined to pursue knowledge of radioactivity in the environment, including movement of radioactive materials and the effects of ionizing radiation on populations and on ecological organization. Volume I contains chapters on ecological principles, radiological principles, environmental radioactivity and radionuclide behavior in ecosystems. Chapter Four on environmental radioactivity characterizes sources, types, and amounts of material and man-made radioactive materials and radiation in the environment. Concepts of radionuclide behavior in ecosystems and behavior (movements and concentrations) of several important element groups in selected ecosystems are surveyed. A chapter on methods used for quantitative predictions of radionuclide transport in the environment gives a reasonably complete treatment to environmental transport processes, radionuclide kinetics in ecosystem compartments, and the use of transport models. Two chapters summarize the known effects of ionizing radiation on species, populations, and higher levels of ecological organization. This information is put into perspective in terms of risk and other consequences. Both volumes are well referenced. Appendices contain listings of major proceedings and books, reviews of specific radionuclides in the environment, and physical data used to characterize radionuclides. The authors succeed in presenting an excellent survey of a broad field of study, and these volumes should serve as a standard reference work on radioecology for a long while

In Finland, workplace surveys are used to identify and assess health risks and problems caused by work and make suggestions for continuous improvement of the work environment. With the aid of the workplace survey, occupational health services can be tailored to a company. The aims of this study were to determine how occupational health professionals gather data via the workplace survey and the effect survey results have on companies. A total of 259 occupational health nurses and 108 occupational health physicians responded to the questionnaire: 84.2% were women and 15.8% were men. The mean age of the respondents was 48.8 years (range, 26 to 65 years). Usually occupational health nurses and foremen and sometimes occupational health physicians and occupational safety and health representatives initiate the workplace survey. More than 90% of the surveys were followed by action proposals, and about 50% of these were implemented. The proposals implemented most often concerned personal protective equipment and less often leadership. Survey respondents should have both the opportunity and the authority to affect resources, the work environment, work arrangements, and tools. Teamwork among occupational health and safety professionals, management, and employees is vital for cost-effectively solving today's complex problems at workplaces around the globe.

Public health practitioners, policy makers, and researchers alike have called for more data on individual worker's perceptions about workplace environment, job satisfaction, and training needs for a quarter of a century. The Public Health Workforce Interests and Needs Survey (PH WINS) was created to answer that call. Characterize key components of the public health workforce, including demographics, workplace environment, perceptions about national trends, and perceived training needs. A nationally representative survey of central office employees at state health agencies (SHAs) was conducted in 2014. Approximately 25,000 e-mail invitations to a Web-based survey were sent out to public health staff in 37 states, based on a stratified sampling approach. Balanced repeated replication weights were used to account for the complex sampling design. A total of 10,246 permanently employed SHA central office employees participated in PH WINS (46% response rate). Perceptions about training needs; workplace environment and job satisfaction; national initiatives and trends; and demographics. Although the majority of staff said they were somewhat or very satisfied with their job (79%; 95% confidence interval [CI], 78-80), as well as their organization (65%; 95% CI, 64-66), more than 42% (95% CI, 41-43) were considering leaving their organization in the next year or retiring before 2020; 4% of those were considering leaving for another job elsewhere in governmental public health. The majority of public health staff at SHA central offices are female (72%; 95% CI, 71-73), non-Hispanic white (70%; 95% CI, 69-71), and older than 40 years (73%; 95% CI, 72-74). The greatest training needs include influencing policy development, preparing a budget, and training related to the social determinants of health. PH WINS represents the first nationally representative survey of SHA employees. It holds significant potential to help answer previously unaddressed questions in public health

Full Text Available Social networks and mobile technologies are transforming learning ecology. In this changing learning environment, we find a variety of new learner needs. The aim of this study is to investigate how to provide scaffolding to the learners in connectivist mobile learning environment: Ø to learn in a networked environment, Ø to manage their networked learning process, Ø to interact in a networked society, and Ø to use the tools belonging to the network society. The researcher described how Vygotsky's “scaffolding” concept, Berge’s “learner support” strategies, and Siemens’ “connectivism” approach can be used together to satisfy mobile learners’ needs. A connectivist mobile learning environment was designed for the research, and the research was executed as a mixed-method study. Data collection tools were Facebook wall entries, personal messages, chat records; Twitter, Diigo, blog entries; emails, mobile learning management system statistics, perceived learning survey and demographic information survey. Results showed that there were four major aspects of scaffolding in connectivist mobile learning environment as type of it, provider of it, and timing of it and strategies of it. Participants preferred mostly social scaffolding, and then preferred respectively, managerial, instructional and technical scaffolding. Social scaffolding was mostly provided by peers, and managerial scaffolding was mostly provided by instructor. Use of mobile devices increased the learner motivation and interest. Some participants stated that learning was more permanent by using mobile technologies. Social networks and mobile technologies made it easier to manage the learning process and expressed a positive impact on perceived learning.

To investigate the impact of nurse practice environment factors, nurse work characteristics, and burnout on nurse reported job outcomes, quality of care, and patient adverse events variables at the nursing unit level. Nurse practice environment studies show growing insights and knowledge about determining factors for nurse workforce stability, quality of care, and patient safety. Until now, international studies have primarily focused on variability at the hospital level; however, insights at the nursing unit level can reveal key factors in the nurse practice environment. A cross-sectional design with a survey. In a cross-sectional survey, a sample of 1108 nurses assigned to 96 nursing units completed a structured questionnaire composed of various validated instruments measuring nurse practice environment factors, nurse work characteristics, burnout, nurse reported job outcomes, quality of care, and patient adverse events. Associations between the variables were examined using multilevel modelling techniques. Various unit-level associations (simple models) were identified between nurse practice environment factors, nurse work characteristics, burnout dimensions, and nurse reported outcome variables. Multiple multilevel models showed various independent variables such as nursing management at the unit level, social capital, emotional exhaustion, and depersonalization as important predictors of nurse reported outcome variables such job satisfaction, turnover intentions, quality of care (at the unit, the last shift, and in the hospital within the last year), patient and family complaints, patient and family verbal abuse, patient falls, nosocomial infections, and medications errors. Results suggested a stable nurse work force, with the capability to achieve superior quality and patient safety outcomes, is associated with unit-level favourable perceptions of nurse work environment factors, workload, decision latitude, and social capital, as well low levels of burnout

Abd Hamid, Nor Hashidah

The purpose of this study was to investigate the extent to which teachers were able to make changes needed to move toward the use of more constructivist behaviors after being involved in the year long Iowa Chautauqua Professional Development Program (ICPDP). Constructivist behaviors were investigated from four perspectives; namely, actual classroom performances as viewed from videotapes, teachers and student perceptions of teacher use of constructivist teaching practices, teacher philosophy as revealed from the open-ended Philosophy of Teaching and Learning Instrument (PTL), and teacher reflections about their inquiry classrooms and uses of questioning strategies. Twenty-seven teacher participants and 321 of their students volunteered to participant in this study. Four types of data were collected to answer the research questions, namely (a) Constructivist Learning Environment Survey (CLES), (b) Philosophies of Teaching and Learning (PTL), (c) Videotapes evaluated with the Expert Science Teaching Evaluation Model (ESTEEM), and (d) Teacher Reflections regarding teaching strategies and questioning. Major findings include the following: (1) Teachers in the project showed significant growth concerning constructivist perceptions over time and for all six sub-scales of TCLES, namely personal relevance, scientific uncertainty, critical voice, shared control, student negotiation, and attitude toward science. (2) Teachers in the project indicated significant growth concerning philosophy of teaching and learning as measured by the PTL. (3) Teachers in the project indicated significant growth concerning constructivist teaching practices as evaluated by videotapes (using the ESTEEM instrument); significant differences were found for all four sub-scales of the ESTEEM. (4) Students in the project indicated significant growth concerning their constructivist perceptions over time for the total SCLES score and on the sub-scales of scientific uncertainty, shared control, and student

A neutron survey meter with a ZnS(Ag) scintillator to measure recoil protons was built. The detection probe weighs ∼2 kg, therefore providing us with true portability. Performance tests exhibited satisfactory neutron dosimetry characteristics in unmoderated or lightly moderated fission neutron fields and in particular work environments at a mixed oxide fuel facility. This new survey meter will augment a routine of neutron monitoring that is inconveniently being carried out by moderator-based neutron survey meters. (authors)

Burnout has a high prevalence among healthcare workers and is increasingly recognised as an environmental problem rather than reflecting a personal inability to cope with work stress. We distributed an electronic survey, which included the Maslach Burnout Inventory Health Services Survey and a previously validated learning environment instrument, to 281 Victorian anaesthetic trainees. The response rate was 50%. We found significantly raised rates of burnout in two of three subscales. Ninety-one respondents (67%) displayed evidence of burnout in at least one domain, with 67 (49%) reporting high emotional exhaustion and 57 (42%) reporting high depersonalisation. The clinical learning environment tool demonstrated a significant negative correlation with burnout (r=-0.56, P Burnout was significantly more common than when previously measured in Victoria in 2008 (62% versus 38%). Trainees rated examination preparation the most stressful aspect of the training program. There is a high prevalence of burnout among Victorian anaesthetic trainees. We have shown a significant correlation exists between the clinical learning environment measure and the presence of burnout. This correlation supports the development of interventions to improve the clinical learning environment, as a means to improve trainee wellbeing and address the high prevalence of burnout.

IntroductionThrough the Science Strategy for Highly Pathogenic Avian Influenza (HPAI) in Wildlife and the Environment, the USGS will assess avian influenza (AI) dynamics in an ecological context to inform decisions made by resource managers and policymakers from the local to national level. Through collection of unbiased scientific information on the ecology of AI viruses and wildlife hosts in a changing world, the U.S. Geological Survey (USGS) will enhance the development of AI forecasting tools and ensure this information is integrated with a quality decision process for managing HPAI.The overall goal of this USGS Science Strategy for HPAI in Wildlife and the Environment goes beyond document­ing the occurrence and distribution of AI viruses in wild birds. The USGS aims to understand the epidemiological processes and environmental factors that influence HPAI distribution and describe the mechanisms of transmission between wild birds and poultry. USGS scientists developed a conceptual model describing the process linking HPAI dispersal in wild waterfowl to the outbreaks in poul­try. This strategy focuses on five long-term science goals, which include:Science Goal 1—Augment the National HPAI Surveillance Plan;Science Goal 2—Determine mechanisms of HPAI disease spread in wildlife and the environment;Science Goal 3—Characterize HPAI viruses circulating in wildlife;Science Goal 4—Understand implications of avian ecol­ogy on HPAI spread; andScience Goal 5—Develop HPAI forecasting and decision-making tools.These goals will help define and describe the processes outlined in the conceptual model with the ultimate goal of facilitating biosecurity and minimizing transfer of diseases across the wildlife-poultry interface. The first four science goals are focused on scientific discovery and the fifth goal is application-based. Decision analyses in the fifth goal will guide prioritization of proposed actions in the first four goals.

Moon, S.W.; Kim, T.W.; Hong, W.H.

2008-01-01

Since modern workers spend more than 80 per cent of their time in indoor environments, it is important to make a comfortable indoor environment in order to maintain occupational health and to improve work efficiency and productivity. Not only are new offices bigger than ever before, the internal heat and air are controlled by a central air conditioning system, which do not allow occupant control. This study evaluated indoor environments of office buildings in an effort to understand how the indoor environment influences work efficiency. The study involved the use of a survey questionnaire to obtain occupants' subjective evaluation of indoor working environments of an office building in terms of thermal comfort, lighting, noise and air quality. The survey results indicated that the indoor environment interrupts the work of many workers. Neck, eye, skin and nasal symptoms were found to be the symptoms most related to the indoor environment, with temperature and humidity posing the greatest challenge. 9 refs., 9 tabs., 7 figs

Objectives Child care is an important setting for the promotion of physical activity (PA) in early childhood. The purpose of this study was to examine the associations between specific PA environments and recommended practices in child care settings as well as the degree to which child care settings met recommended standards for total PA time. Methods In 2013, all programs licensed to care for children ages 2-5 in WA state were surveyed about their PA related practices. Logistic regression was used to determine odds of meeting best-practice standards for outdoor time and PA. Results The response rate was 45.8 % from centers (692/1511) and 32.1 % from homes (1281/3991). Few programs reported meeting best-practice standards for the amount of time children spend being physically active (centers: 12.1 %, homes: 20.1 %) and outdoor time (centers: 21.8 %, homes: 21.7 %). Programs where children go outside regardless of weather and those reporting more adult-led PA had higher odds of meeting best-practice standards for both PA and outdoor time. Meeting best-practice standards for outdoor time was the strongest predictor of meeting best-practice standards for total PA time [centers: OR 15.9 (9.3-27.2), homes: OR 5.2 (3.8-7.1)]. Conclusions for Practice There is considerable room for improvement in licensed child care settings in WA to meet best-practice standards for young children's outdoor and PA time. Initiatives that create policies and environments encouraging outdoor play and adult-led PA in child care have the potential to increase physical activity in substantial numbers of young children.

As part of the 2014 ACR Human Resources Commission Workforce Survey, an assessment of the gender of the U.S. radiologist workforce was undertaken. Radiologist gender in relation to type of practice, work location, leadership roles, and full- versus part-time employment have not previously been assessed by this survey. The survey was completed by group leaders in radiology identified through the Practice of Radiology Environment Database. The response rate to the survey was 22%, representing 35% of all practicing radiologists. The survey found that 78% of the radiology workforce is male, and 22% female. Among the men, 58% work in private practice, and 18% in the academic/university environment; among women, percentages were 43% and 31%, respectively. Of all physician leads, 85% are men, 15% women. Of the full-time radiologists, 15% of men are practice leaders compared with 11% of women. Fewer women than men are in private practice. More women than men practice in academic/university environments. Among part-time radiologists, there are more men than women, but significantly more women work part time than men. Women are in the minority among practice leaders. Copyright © 2015 American College of Radiology. Published by Elsevier Inc. All rights reserved.

Nuclear facilities located at Kalpakkam in Tamil Nadu State of India include at present nuclear power reactors, a fast breeder reactor, a nuclear research centre and a waste management facility. Active wastes generated at the site are collected, treated and safely disposed. High-level wastes are stored underground in RCC trenches and tile hole and low-level wastes in the from of liquid effluents are discharged into the sea. Off-gases are dispersed through stacks in the atmosphere. Environmental survey laboratory established at the site in 1974 carries out radiation surveillance of the environment, evaluates radiological impacts on environment and public, and assesses radiation exposure of the population. It is observed that even after five years of operation of the nuclear power station, radioactivity and radiation levels in the environment have virtually remained at the pre-operational levels.

In order to measure the airborne radioactive substance concentration in working environments, some kinds of sampler such as dust sampler and iodine sampler, measuring instruments (alpha and beta spectrometer, and liquid scintillation counter), monitor (dust-, iodine- and gas-monitor), survey meter for measuring gamma ray dose rate are stated. The measurement method of α, β and γ-ray nuclides and ambient dose-equivalent at 10 mm was explained. Some examples of the list of dust sampler, filter, tritium sampler, dust monitor, iodine monitor, gas monitor, and survey meter on the market are shown. There are so many kinds of measuring instruments for ionizing radiation in working environment that the best instrument for measurement should be selected. The environment conditions such as sample form, temperature and humidity have to be considered in order to evaluate the measurement values. (S.Y.)

To determine whether nurse coworker incivility is associated with the nurse work environment, defined as organisational characteristics that promote nurse autonomy. Workplace incivility can negatively affect nurses, hospitals and patients. Plentiful evidence documents that nurses working in better nurse work environments have improved job and health outcomes. There is minimal knowledge about how nurse coworker incivility relates to the United States nurse work environment. Quantitative, cross-sectional. Data were collected through online surveys of registered nurses in a southwestern United States health system. The survey content included the National Quality Forum-endorsed Practice Environment Scale of the Nursing Work Index and the Workplace Incivility Scale. Data analyses were descriptive and correlational. Mean levels of incivility were low in this sample of 233 staff nurses. Incivility occurred 'sporadically' (mean = 0.58; range 0.00-5.29). The nurse work environment was rated highly (mean = 3.10; range of 1.00-4.00). The nurse work environment was significantly inversely associated with coworker incivility. The nurse manager qualities were the principal factor of the nurse work environment associated with incivility. Supportive nurse managers reduce coworker incivility. Nurse managers can shape nurse work environments to prevent nurse incivility. © 2017 John Wiley & Sons Ltd.

The rapid increase in technological development and the broad societal benefit it has brought has been accompanied by a corresponding increase in environmental and societal problems. This has established a need to asses the impacts of new technologies, including nuclear industries. We are now entering an age which will see a rapid proliferation of nuclear power plants all over the world. As long as man continues to utilize nuclear energy, some releases of radioactive materials to the environment seem to be inescapable consequences. The problem therefore is to limit and control such releases, so that adverse effects on man and his environment can be reduced to acceptable levels. We can now draw on three decades of experience of the environmental impact of radioactive materials. To review this experience and to survey recent results of studies related to the safety of releases of nuclear facilities into fresh water, estuaries and sea water, the International Symposium on 'Radiological Impacts of Releases from Nuclear Facilities into Aquatic Environments' was held at Otaniemi, near Helsinki, Finland.

Analysis used t-tests or chi-square analysis as appropriate. The primary endpoint was bicycle use or walking. The predictor variables were the Walk Score® as determined by their address, Charlson index, Duke Activity Status Index (DASI, and a 12-item short-form survey (SF-12 scores. Secondary analysis used an outcome of functional status (using the DASI and walkability scores.Results: Fifty-three individuals completed the surveys (48% return rate. The average age in the overall cohort was 77.02 years. Eighty-nine percent of individuals could walk at least a block and 15.1% rode their bicycles. The Walk Scores® did not differ between those who walked (38.9 ± 27.4 and those that did not (40.0 ± 36.08; P = 0.93. In a similar fashion, the Walk Scores® were not different for those who biked (36.38 ± 27.68 and those that did not (39.44 ± 28.49; P = 0.78. There was no relationship between Walk Scores® and DASI; however, a decreased DASI score was associated with increased age and comorbid illness (Charlson Score.Conclusion: In this small pilot survey, there was no difference in Walk Scores® between those older adults who walked or biked, compared to those that did not. The Walk Scores® were low in both groups, which may indicate the lack of accessibility for all older adults living in Rochester, Minnesota. The functional status seemed to be more related to age or comorbid conditions than the built environment

Development of an innovative, integrated, automated system (Global Positioning Site Environment Evaluator - GPSEETM) for surveying contaminated waste sites is described. This system makes novel use of the Global Positioning System (GPS) satellite constellation for establishing specific locations and current times for surveying radioactive, hazardous, or mixed-waste sites. GPSEE may also be used for waste site contamination surveys after remediation activities to ensure environmental remediation is complete. A base station is established for collecting and recording data and directing field operations for field stations which may be located many miles from the base station. The field operators collect site surveying and contamination data utilizing a variety of chemical and radiological sensors. A major goal for the data collection process is to collect all data utilizing in situ sensors, thereby minimizing the need for collecting soil and water samples. Site contamination data is transmitted electronically to the base station for recording and processing. The GPSEE system is being developed for use at DOE/DOD and a variety of industrial facilities. 3 figs

Consequences of electricity restructuring on the environment: A survey

International Nuclear Information System (INIS)

Sevi, Benoit

2004-01-01

The aim of this paper is to assess theoretical consequences of restructuring electricity markets on the environment. We examine changes in potential behaviours in consumption-side as well as in supply-side. We show that restructuring and following access to competition is not neutral from an environmental standpoint. Deregulation could induce some negative externalities due to requirements in cost-efficiency. The principal result of this paper is the need of strong incentives in public policies to compensate the new short-term horizon in which energy sector's firms are evolving, particularly concerning R and D.

This study used a marketing-research paradigm to explore gamblers' attraction to EGMs based on different elements of the environment. A select set of environmental features was sourced from a prior study (Thorne et al. in J Gambl Issues 2016b), and a discrete choice experiment was conducted through an online survey. Using the same dataset first described by Rockloff et al. (EGM Environments that contribute to excess consumption and harm, 2015), a sample of 245 EGM gamblers were sourced from clubs in Victoria, Australia, and 7516 gamblers from an Australian national online survey-panel. Participants' choices amongst sets of hypothetical gambling environments allowed for an estimation of the implied individual-level utilities for each feature (e.g., general sounds, location, etc.). K-means clustering on these utilities identified four unique market segments for EGM gambling, representing four different types of consumers. The segments were named according to their dominant features: Social, Value, High Roller and Internet. We found that the environments orientated towards the Social and Value segments were most conducive to attracting players with relatively few gambling problems, while the High Roller and Internet-focused environments had greater appeal for players with problems and vulnerabilities. This study has generated new insights into the kinds of gambling environments that are most consistent with safe play.

The IMACS Cluster Building Survey uses the wide field spectroscopic capabilities of the IMACS spectrograph on the 6.5 m Baade Telescope to survey the large-scale environment surrounding rich intermediate-redshift clusters of galaxies. The goal is to understand the processes which may be transforming star-forming field galaxies into quiescent cluster members as groups and individual galaxies fall into the cluster from the surrounding supercluster. This first paper describes the survey: the data taking and reduction methods. We provide new calibrations of star formation rates (SFRs) derived from optical and infrared spectroscopy and photometry. We demonstrate that there is a tight relation between the observed SFR per unit B luminosity, and the ratio of the extinctions of the stellar continuum and the optical emission lines. With this, we can obtain accurate extinction-corrected colors of galaxies. Using these colors as well as other spectral measures, we determine new criteria for the existence of ongoing and recent starbursts in galaxies.

FFTF preoperational survey. Program report

Twitty, B.L.; Bicehouse, H.J.

1980-12-01

The FFTF will become operational with criticality early in 1980. This facility is composed of the test reactor, fuel examination cells, expended fuel storage systems and fuel handling systems. The reactor and storage systems are sodium-cooled with the heat load dumped to the ambient air through heat exchangers. In order to assure that the operation of the FFTF has minimal impact on the environment, a monitoring program has been established. Prior to operation of a new facility, a preoperational environmental survey is required. It is the purpose of this report to briefly describe the environmental survey program and to provide the background data obtained during the preoperational phase of the survey program. Nine stations in the program of particular importance to FFTF are discussed in detail with results of monitoring given. No unexplained trends were noted

Although burnout is viewed as a syndrome rooted in the working environment and organizational culture, the role of the learning environment in the development of resident burnout remains unclear. We aimed to evaluate the association between burnout and the learning environment in a cohort of Belgian residents. We conducted a cross-sectional online survey among residents in a large university hospital in Belgium. We used the Dutch version of the Maslach Burnout Inventory (UBOS-C) to assess burnout and the Dutch Residency Educational Climate Test (D-RECT) to assess the learning environment. A total of 236 residents (29 specialties) completed the survey (response rate 34.6%), of which 98 (41.5%) met standard criteria for burnout. After multivariate regression analysis adjusting for hours worked per week, quality of life and satisfaction with work-life balance, we found an inverse association between D-RECT scores and the risk of burnout (adjusted odds ratio; 0.47 for each point increase in D-RECT score; 95% CI, 0.23 - 0.95; p = 0.01). Resident burnout is highly prevalent in our cohort of Belgian residents. Our results suggest that the learning environment plays an important role in reducing the risk of burnout among residents.

The Pulsar Arecibo L-band Feed Array (PALFA) Survey uses the ALFA 7-beam receiver to search both inner and outer Galactic sectors visible from Arecibo (32° ≲ ℓ ≲ 77° and 168° ≲ ℓ ≲ 214°) close to the Galactic plane (|b| ≲ 5°) for pulsars. The PALFA survey is sensitive to sources fainter and more distant than have previously been seen because of Arecibo's unrivaled sensitivity. In this paper we detail a precursor survey of this region with PALFA, which observed a subset of the full region (slightly more restrictive in ℓ and |b| ≲ 1°) and detected 45 pulsars. Detections included 1 known millisecond pulsar and 11 previously unknown, long-period pulsars. In the surveyed part of the sky that overlaps with the Parkes Multibeam Pulsar Survey (36° ≲ ℓ ≲ 50°), PALFA is probing deeper than the Parkes survey, with four discoveries in this region. For both Galactic millisecond and normal pulsar populations, we compare the survey's detections with simulations to model these populations and, in particular, to estimate the number of observable pulsars in the Galaxy. We place 95% confidence intervals of 82,000 to 143,000 on the number of detectable normal pulsars and 9000 to 100,000 on the number of detectable millisecond pulsars in the Galactic disk. These are consistent with previous estimates. Given the most likely population size in each case (107,000 and 15,000 for normal and millisecond pulsars, respectively), we extend survey detection simulations to predict that, when complete, the full PALFA survey should have detected 1000{sub −230}{sup +330} normal pulsars and 30{sub −20}{sup +200} millisecond pulsars. Identical estimation techniques predict that 490{sub −115}{sup +160} normal pulsars and 12{sub −5}{sup +70} millisecond pulsars would be detected by the beginning of 2014; at the time, the PALFA survey had detected 283 normal pulsars and 31 millisecond pulsars, respectively. We attribute the deficiency in normal pulsar

An operating room (OR) environment is challenging and complicated. At any given time, several vital tasks are being performed by skilled individuals, including physicians, nurses, and ancillary staff. There is a potential for multifactorial mistakes; many arise because of communication issues. To evaluate the current state of perceptions of interdisciplinary communication in an OR setting, a survey was developed and administered to four academic residency training departments of anesthesiology in a single U.S. state. The results of this survey show that perceived poor communication within the OR leads to a lack of emphasis on a multidisciplinary approach to patient care in the OR. Survey data can be used internally to identify shortcomings in communication at a facility, to stress the importance of communication, and to serve as a powerful education tool to potentially improve patient care. Through this type of survey, which emphasizes communication in the OR, stakeholders can work more effectively to improve patient care and decrease adverse outcomes in the hospital environment.

Wireless Sensor Applications in Extreme Aeronautical Environments

Wilson, William C.; Atkinson, Gary M.

2013-01-01

NASA aeronautical programs require rigorous ground and flight testing. Many of the testing environments can be extremely harsh. These environments include cryogenic temperatures and high temperatures (greater than 1500 C). Temperature, pressure, vibration, ionizing radiation, and chemical exposure may all be part of the harsh environment found in testing. This paper presents a survey of research opportunities for universities and industry to develop new wireless sensors that address anticipated structural health monitoring (SHM) and testing needs for aeronautical vehicles. Potential applications of passive wireless sensors for ground testing and high altitude aircraft operations are presented. Some of the challenges and issues of the technology are also presented.

2014-03-24

The Dundee Ready Education Environment Measure (DREEM) has been widely used to evaluate the learning environment within health sciences education, however, this tool has not been applied in veterinary medical education. The aim of this study was to evaluate the reliability and validity of the DREEM tool in a veterinary medical program and to determine veterinary students' perceptions of their learning environment. The DREEM is a survey tool which quantitatively measures students' perceptions of their learning environment. The survey consists of 50 items, each scored 0-4 on a Likert Scale. The 50 items are subsequently analysed within five subscales related to students' perceptions of learning, faculty (teachers), academic atmosphere, and self-perceptions (academic and social). An overall score is obtained by summing the mean score for each subscale, with an overall possible score of 200. All students in the program were asked to complete the DREEM. Means and standard deviations were calculated for the 50 items, the five subscale scores and the overall score. Cronbach's alpha was determined for the five subscales and overall score to evaluate reliability. Confirmatory factor analysis was used to evaluate construct validity. 224 responses (53%) were received. The Cronbach's alpha for the overall score was 0.93 and for the five subscales were; perceptions of learning 0.85, perceptions of faculty 0.79, perceptions of atmosphere 0.81, academic self-perceptions 0.68, and social self-perceptions 0.72. Construct validity was determined to be acceptable (p education programs. Four individual items of concern were identified by students. In this setting the DREEM was a reliable and valid tool to measure veterinary students' perceptions of their learning environment. The four items identified as concerning originated from four of the five subscales, but all related to workload. Negative perceptions regarding workload is a common concern of students in health education

The aim of this study was to achieve improvements in the work environment of Japanese surgeons and shortage of surgeons. Questionnaires were distributed to selected Japanese surgical Society (JSS) members. Retrospective analysis was conducted comparing the current 2011 survey with previous 2007 survey. To examine the influence of 2010 revision of the fee for medical services performed by surgeons, we distributed a second questionnaire to directors of hospitals and administrators of clerks belonging to official institutes in JSS. Collective data were analyzed retrospectively. The main potential causes for the shortage of surgeons in Japan were long hours (72.8 %), excessive emergency surgeries (69.4 %), and high risk of lawsuit (67.7 %). Mean weekly working hours of surgeons in national or public university hospitals and private university hospitals were 96.2 and 85.6, respectively. Approximately 70 % of surgeons were forced to do hardworking tasks, possibly leading to death from overwork. Of note, approximately 25 % of surgeons had over time of more than 100 h a week, coinciding to the number of hours that might lead to death from fatigue, described in the Japanese labor law. Although the total medical service fee in hospitals, especially in large-scale hospitals with more than 500 beds, increased markedly after 2010 revision of the fee for medical services performed by surgeons, few hospitals gave perquisites and/or incentives to surgeons. To prevent and avoid collapse of the surgical specialty in Japan, an improvement in the work environment of surgeons by initiation of the JSS would be required as soon as possible.

Soil emanometry possibilities in assessment of different influences on environment

International Nuclear Information System (INIS)

Mojzes, A.

2004-01-01

Radioactive gas radon having origin in mineral composition of rocks is a dangerous radio-toxic element. This fact imposes a need of its detection and quantification with the aid of radon risk assessment in either geological basement or living rooms. Except for this it is possible to use the radon detection, thanks to its relatively simple measurement, for purposes of geological near-surface structure characterization because this object has also a direct influence on human environment. The goal of contribution is to present an attempt of utilization of field emanation survey (in complex with other geophysical survey methods) as means to closer and more detailed definition of that part of geological environment which is affected by both human activity of undermining and natural tectonic faults. In situ field measurements were carried out in the Homa Nitra Region whose environment is heavily burdened with such factors. (authors)

Community-wide efforts to encourage healthy behaviours must respond to the needs of existing neighbourhoods, especially those where low physical activity (PA) is associated with social, economic, and cultural challenges. This study reports on the effect of direct and snowball sampling strategies and financial incentive levels on the response rates of a built environment and PA survey in a predominately urban, low-SES new-immigrant community. Women residing in the Jane-Finch neighbourhood of Toronto, Ontario were selected to participate by quasi-random sampling, yielding a response rate of 41.5%. The survey completion rate per contact attempt increased 2-fold when incentives were increased from $10 to $20 and a further threefold following the increase from $20 to $30. Snowball sampled respondents were older, less likely to have full-time employment, and had lower educational attainment than directly sampled participants. With appropriate incentives, face-to-face contact, and snowball sampling, survey-based research is feasible within a low-SES, high minority population.

Strasser, D C; Falconer, J A; Martino-Saltzmann, D

1994-02-01

Although inpatient rehabilitation is an interdisciplinary activity organized around a treatment team, there is a limited understanding of the workings of the interdisciplinary process. To elucidate staff perceptions of key aspects of the rehabilitation treatment process, we surveyed staff (n = 113) from selected inpatient teams. The staff completed social psychological instruments that measure perceptions of the hospital environment (The Ward Atmosphere Scale [WAS]), the team's environment (the Group Environment Scale [GES]), and interprofessional relations (Interprofessional Perception Scale [IPS]). Rehabilitation staff generally endorse the team approach, but express concerns over professional boundaries. Interprofessional difficulties seemed to be independent of team membership or professional training. Compared with published data from other settings, rehabilitation teams resembled task-oriented groups, but showed significant differences across teams in their perceptions of the team and hospital environments. The task-oriented character of rehabilitation teams, team-specific characteristics, and discord in interprofessional relationships may need to be considered in studies of rehabilitation teams effectiveness.

The Culture of Academic Medicine: Faculty Behaviors Impacting the Learning Environment.

Science.gov (United States)

Moutier, Christine; Wingard, Deborah; Gudea, Monica; Jeste, Dilip; Goodman, Seneca; Reznik, Vivian

2016-12-01

The culture of academic medical institutions impacts trainee education, among many other faculty and patient outcomes. Disrespectful behavior by faculty is one of the most challenging and common problems that, left unattended, disrupts healthy work and learning environments. Conversely, a respectful environment facilitates learning, creates a sense of safety, and rewards professionalism. The authors developed surveys and an intervention in an effort to better understand and improve climate concerns among health sciences faculty at the University of California, San Diego (UCSD), a research-intense, public, academic medical center. An online "climate survey" of all UC San Diego health sciences faculty was conducted in 2011-2012. A strategic campaign to address the behavioral issues identified in the initial survey was subsequently launched. In 2015, the climate was re-evaluated in order to assess the effectiveness of the intervention. A total of 478 faculty members (223 women, 235 men, 35 % of faculty) completed the baseline survey, reporting relatively low levels of observed sexual harassment (7 %). However, faculty reported concerning rates of other disruptive behaviors: derogatory comments (29 %), anger outbursts (25 %), and hostile communication (25 %). Women and mid-level faculty were more likely to report these behavioral concerns than men and junior or senior colleagues. Three years after an institutional strategy was initiated, 729 faculty members (50 % of the faculty) completed a follow-up survey. The 2015 survey results indicate significant improvement in numerous climate factors, including overall respectful behaviors, as well as behaviors related to gender. In order to enhance a culture of respect in the learning environment, institutions can effectively engage academic leaders and faculty at all levels to address disruptive behavior and enhance positive climate factors.

SELF-ASSEMBLED ROV AND PHOTOGRAMMETRIC SURVEYS WITH LOW COST TECHNIQUES

2018-05-01

Full Text Available In last years, ROVs, have been employed to explore underwater environments and have played an important role for documentation and surveys in different fields of scientific application. In 2017, the Laboratorio di Fotogrammetria of Iuav University of Venice has decided to buy an OpenRov, a low cost ROV that could be assembled by ourselves to add some external components for our necessities, to document archaeological sites. The paper is related to the photogrammetric survey for the documentation of underwater environments and to the comparison between different solutions applied on a case studio, five marble columns on a sandy bottom at 5 meters deep. On the lateral sides of the ROV, we have applied two GoPro Hero4 Session, which have documented the items both with a series of images and with a video. The geometric accuracy of the obtained 3D model has been evaluated through comparison with a photogrammetric model realized with a professional reflex camera, Nikon D610. Some targets have been topographically surveyed with a trilateration and have been used to connected in the same reference system the different models, allowing the comparisons of the point clouds. Remote Operating Vehicles offer not only safety for their operators, but are also a relatively low cost alternative. The employment of a low-cost vehicle adapted to the necessities of surveys support a request for safer, cheaper and efficient methods for exploring underwater environments.

Perez Barbosa, David; Zhang, Junyi; Seya, Hajime

2016-02-03

This paper aims to clarify how the residential environment is associated with overall health-related quality of life (QOL) via active travel (walking and cycling), by reflecting the influence of different trip purposes in Japan. The health-related QOL includes physical, mental, and social dimensions. For this study we implemented a questionnaire survey in 20 cities in Japan in 2010 and obtained valid answers from 1202 respondents. The residential environment is defined in terms of distances to and densities of different daily facilities extracted from both the survey and external GIS data. We found that the effects of residential environment on active travel behavior are mixed and limited, depending on types of trip makers. Unexpectedly, travel behavior has no direct effects on the health-related QOL. The residential environment, which is only observed indirectly via lifestyle habits for commuters, has limited effects on health. As for noncommuters, neither their travel behavior nor the residential environment influences their health-related QOL.

This report presents the questions and responses to a nationwide survey taken June 2016 to track preferences of US residents concerning the environment, energy, and radioactive waste management. A focus of the 2016 survey is public perceptions on different options for managing spent nuclear fuel, including on-site storage, interim storage, deep boreholes, general purpose geologic repositories, and geologic repositories for only defense-related waste. Highlights of the survey results include the following: (1) public attention to the 2011 accident and subsequent cleanup at the Fukushima nuclear facility continues to influence the perceived balance of risk and benefit for nuclear energy; (2) the incident at the Waste Isolation Pilot Plant in 2014 could influence future public support for nuclear waste management; (3) public knowledge about US nuclear waste management policies has remined higher than seen prior to the Fukushima nuclear accident and submittal of the Yucca Mountain application; (6) support for a mined disposal facility is higher than for deep borehole disposal, building one more interim storage facilities, or continued on-site storage of spent nuclear fuel; (7) support for a repository that comingles commercial and defense related waste is higher than for a repository for only defense related waste; (8) the public’s level of trust accorded to the National Academies, university scientists, and local emergency responders is the highest and the level trust accorded to advocacy organizations, public utilities, and local/national press is the lowest; and (9) the public is willing to serve on citizens panels but, in general, will only modestly engage in issues related to radioactive waste management.

To date, no studies have explored how different regulatory environments may influence the effectiveness of electronic cigarettes (ECs) as a smoking cessation aid. This study compares the real-world effectiveness of adult smokers using ECs for quitting compared with quitting unassisted or quitting with nicotine replacement therapy (NRT) and/or prescription medications in two countries with restrictive policies towards ECs (ie, Canada and Australia) versus two countries with less restrictive policies (ie, United States and United Kingdom). Data were drawn from the International Tobacco Control Four Country surveys, from the United States and Canada (2 waves, n = 318 and 380, respectively), the United Kingdom (3 waves, n = 439) and Australia (4 waves, n = 662), collected 2010-2014. Smokers at baseline wave who reported making a quit attempt at follow-up were included. The primary outcome was self-reported abstinence for at least 30 days regardless of smoking status at follow-up assessment. Data across waves were combined and analyzed using generalized estimating equations. Compared to unassisted quitting (ie, no medications or ECs), smokers who used ECs for quitting from countries with less restrictive EC policy environments were more likely (OR = 1.95, 95%CI = 1.19-3.20, p cessation are likely highly dependent on the regulatory environment. What this study adds: This is the first study to examine the impact of regulatory environment for ECs on their real-world effectiveness for smoking cessation. This study shows that in a less restrictive EC regulatory environment, use of ECs during a quit attempt facilitates, but in a more restrictive environment, it inhibits, short-term sustained abstinence. The findings underscore the need for careful consideration on how best to regulate this emerging product so that EC benefits for smoking cessation are maximized and its risks to public health are minimized. © The Author 2017.

A survey of the urban radiofrequency (RF) environment

Tell, Richard A.; Kavet, Robert

2014-01-01

In 1980, Tell and Mantiply published a study of radiofrequency (RF) fields measured across 15 major metropolitan areas in the USA. They required a van fully equipped with instrumentation and computing capability for their measurements. This study aimed to assess whether and how hand-held instrumentation available today would facilitate and enhance the efficiency of large-scale surveys of ambient RF fields. In addition, the data would provide a suggestion as to how the profile of ambient RF fields has changed with respect to frequency content and magnitude. Not unexpectedly, the relative power densities were orders of magnitude lower than the Federal Communications Commission's (FCC) maximum permissible exposure (MPE) for the general public, with a maximum time-averaged value across the VHF-FM-UHF-cellular bands of 0.12 % of the MPE (AM's contribution was negligible). In both the 1980 and the present study, the power density in the FM band was a major contributor to overall power density, but over time, power densities in the VHF and UHF band decreased and increased, respectively. From the perspective of absolute power density, the wideband values in the 1980 study, this study and any number of assessments conducted in European nations are not generally different from one another.

2008-08-01

This report describes the survey operation, survey and processing methods and the deliverables of an aerogeophysical survey in Olkiluoto area in April 2008. The survey was conducted by Geological Survey of Finland (GTK). The survey aircraft was a twin-engine Twin Otter operated by Finnish Aviation Academy (SIO) and owned by Natural Environment Research Council / British Geological Survey (NERC / BGS), with whom GTK has established a joint venture called Joint Airborne-geoscience Capability (JAC). The survey was conducted in April 2008 during six days. The survey consists of six separate survey flights, one of which was a magnetic calibration flight. The survey was based in Pori airport. Survey line spacing was 50 meters and nominal survey altitude was 30 meters. Measurements were completed in April 2008, and data processing and reporting was done in June 2008. Two cesium magnetometers installed onboard the aircraft (at the left wingtip and in a nose cone) were measuring the magnetic total field intensity during the survey flights. An automatic compensation unit corrected the aircraft attitude errors in the magnetic data in real time. In addition to magnetic measurement, auxiliary parameters such as flight altitude and aircraft attitude were also recorded simultaneously. Reference ground base station was used for recording the temporal variations in the magnetic field and also reference data for post-positioning of coordinate information. In the post-processing phase, heading correction, base station correction and microlevelling procedures were applied to the magnetic data. The data was exported to numeric XYZ files and interpolated into grid data file. A noteworthy local detail present in the survey and in the processing was the massive power line. For safety reasons, flight altitude had to be increased and survey lines had to be cut short in the vicinity of the powerline. However, due to reasonable planning of the survey area boundaries, this caused no great

While trucking in industrialized nations is linked with driver health afflictions, the role of trucking in U.S. truckers' health remains largely unknown. This paper sheds light on links between the trucking work environment and drivers' physical health. Using a cross-sectional design, 316 truckers were enrolled in the Healthy Trucker Survey. Questions included work history, physical and mental health, and healthcare access. PASW 18 was used to examine patterns among factors. 316 truckers participated. Respondents were mainly full-time, long-haul drivers with over 5 years of experience, and who spent over 17 days on the road per month. While almost 75% described their health as good, 83.4% were overweight/obese, 57.9% had sleeping disturbances, 56.3% fatigue, 42.3% musculoskeletal disorders, and about 40% cardiovascular disease concerns. About 33% had no health insurance, 70% had no regular healthcare visits, 24.4% could not afford insurance, and 42.1% took over-the-counter drugs when sick, while 20.1% waited to reach home for medical care. Exercise facilities were unavailable in over 70% of trucking worksites and 70% of drivers did not exercise regularly. The trucking occupation places drivers at high risk for poor health outcomes. Prospective studies are needed to delve into how continued exposure to trucking influences the progression of disease burden.

Mental wellbeing, conceptualised as positive affect, life satisfaction and realisation of needs that contribute to psychological growth, captures more than the absence of mental ill health. Several nations now aim to monitor and improve mental wellbeing. Whilst many studies document associations between adverse childhood experiences and mental disorders in adulthood, possible links between childhood experiences and adult mental wellbeing have so far received less attention. Using data from 1976 men and women in the MRC National Survey for Health and Development, we investigated prospective associations between childhood socioeconomic and psychosocial environments and the Warwick Edinburgh Mental Wellbeing Scale, designed to capture both hedonic and eudaimonic facets of wellbeing, at age 60-64. Whilst there was no evidence that childhood socioeconomic circumstances were related to later wellbeing independently of other childhood experiences, elements of childrearing and parenting, parental health and adjustment, and childhood illness were related. More advantaged socioeconomic position was associated with greater wellbeing but this did not explain the links between these childhood exposures and adult wellbeing, suggesting alternative explanatory pathways should be considered. Childhood illness and family psychosocial environment are associated with mental wellbeing in early older age, with effects sizes that are larger or comparable to socioeconomic circumstances in adulthood. Initiatives to improve the nation's mental wellbeing that include programmes targeted to supporting families and children may additionally have benefits that continue into older age.

Full Text Available The objective of this paper is to establish a picture of to what extent Green Supply Chain Management is present in Bosnia and Herzegovina. Another point of interest in this paper is the measurement of administrative environment, consumer perception and the actual implementation of such a supply chain into daily operations. This study develops a survey questionnaire based on the reviewed literature about Green Supply Chain Management, and conducts the survey on the employees of companies located in one region of Bosnia and Herzegovina and compares the obtained results with the work of others in this field. The findings in this paper are conclusive and indicate a strong tendency towards complete implementation of Green Supply Chain Management into daily operations of Bosnian production companies, an existence of a supportive administrative environment and the strong willingness of people to adapt measures that are acceptable to the environment and create a smaller social cost. Finally, this paper is a testimony of good intent towards the environment supported and executed by those striving to achieve more efficient and less costly, socially acceptable and environmentally healthy solutions for conducting their business.

1980-01-01

Under the NIOSH-sponsored contract, a total of 40 surveys were conducted at 28 manufacturing plants. The industries investigated were the fish, dye, leather, rubber and manufacturers and users of cutting fluids. NDELA, NMOR, NDMA and NDPhA were found in the air of several factories. In a chrome tannery, NDMA was identified at levels as high as 47 micrograms/m3 and NMOR was found at 27 micrograms/m3 in a rubber tire plant. This study has resulted in an increased understanding of man's exposure to exogenous N-nitrosamines. It is conceivable, from the information obtained in this study, that nitrosamine exposure comparable to that in the tire and rubber industry exists in other industries not yet surveyed. NIOSH is continuing its research on nitrosamines in the industrial environment. A full, industry-wide report on the 40 plant surveys is being compiled for publication.

The Smoke-Free Ontario Act (SFOA) came into effect in May 2006 and included restrictions to outdoor hospitality areas by only permitting smoking on a patio if the area had no roof. (1) To assess the impact of the SFOA on the prevalence of smoke-free patios in Ontario and (2) to determine the proportion of venues where structural alterations were made rather than going smoke-free in order to achieve compliance with the SFOA. A telephone survey of 403 hospitality sector operators/owners in four clustered samples of Ontario, Canada. Based on completed surveys, the SFOA resulted in an increase in prevalence of smoke-free patios, from 5% (n=21) to 25% (n=99). Of the patios where smoking was permitted before the SFOA (n=382), 42% (n=161) had physical structures that would make smoking not permissible under the new act. Operators of half of these venues (n=80) made their patios smoke-free, with most indicating they had no choice given the costs or physical limitations to changing their outdoor environment. The other half (n=81) reported making physical changes, including removing roof structures to achieve compliance. The SFOA resulted in greater protection from outdoor secondhand smoke; however, most patios still permitted smoking. Half of the venues that complied with the SFOA by going smoke-free did so involuntarily because of structural and/or financial limitations. The majority of venue operators preferred to permit smoking on their patios, and only made their patios smoke-free when they were required to do so by law.

To explore the mechanisms through which nurse practice environment dimensions are associated with job outcomes and nurse-assessed quality of care. Mediating variables tested included nurse work characteristics of workload, social capital, decision latitude, as well as burnout dimensions of emotional exhaustion, depersonalization, and personal accomplishment. Acute care hospitals face daily challenges to their efforts to achieve nurse workforce stability, safety, and quality of care. A body of knowledge shows a favourably rated nurse practice environment as an important condition for better nurse and patient outcome variables; however, further research initiatives are imperative for a clear understanding to support and guide the practice community. Cross-sectional survey. Grounded on previous empirical findings, a structural equation model designed with valid measurement instruments was tested. The study population was registered acute care nurses (N=1201) in two independent hospitals and one hospital group with six hospitals in Belgium. Nurse practice environment dimensions predicted job outcome variables and nurse ratings of quality of care. Analyses were consistent with features of nurses' work characteristics including perceived workload, decision latitude, and social capital, as well as three dimension of burnout playing mediating roles between nurse practice environment and outcomes. A revised model adjusted using various fit measures explained 52% and 47% of job outcomes and nurse-assessed quality of care, respectively. The study refines understanding of the relationship between aspects of nursing practice in order to achieve favourable nursing outcomes and offers important concepts for managers to track in their daily work. The findings of this study indicate that it is important for clinicians and leaders to consider how nurses are involved in decision-making about care processes and tracking outcomes of care and whether they are able to work with

The Dark Energy Survey (DES) collaboration will study cosmic acceleration with a 5000 deg2 griZY survey in the southern sky over 525 nights from 2011-2016. The DES data management (DESDM) system will be used to process and archive these data and the resulting science ready data products. The DESDM system consists of an integrated archive, a processing framework, an ensemble of astronomy codes and a data access framework. We are developing the DESDM system for operation in the high performance computing (HPC) environments at the National Center for Supercomputing Applications (NCSA) and Fermilab. Operating the DESDM system in an HPC environment offers both speed and flexibility. We will employ it for our regular nightly processing needs, and for more compute-intensive tasks such as large scale image coaddition campaigns, extraction of weak lensing shear from the full survey dataset, and massive seasonal reprocessing of the DES data. Data products will be available to the Collaboration and later to the public through a virtual-observatory compatible web portal. Our approach leverages investments in publicly available HPC systems, greatly reducing hardware and maintenance costs to the project, which must deploy and maintain only the storage, database platforms and orchestration and web portal nodes that are specific to DESDM. In Fall 2007, we tested the current DESDM system on both simulated and real survey data. We used TeraGrid to process 10 simulated DES nights (3TB of raw data), ingesting and calibrating approximately 250 million objects into the DES Archive database. We also used DESDM to process and calibrate over 50 nights of survey data acquired with the Mosaic2 camera. Comparison to truth tables in the case of the simulated data and internal crosschecks in the case of the real data indicate that astrometric and photometric data quality is excellent

Many residency programs offer training in evidence-based medicine (EBM). However, these curricula often fail to achieve optimal learning outcomes, perhaps because they neglect various contextual factors in the learning environment. We developed and validated an instrument to characterize the environment for EBM learning and practice in residency programs. An EBM Environment Scale was developed following scale development principles. A survey was administered to residents across six programs in primary care specialties at four medical centers. Internal consistency reliability was analyzed with Cronbach's coefficient alpha. Validity was assessed by comparing predetermined subscales with the survey's internal structure as assessed via factor analysis. Scores were also compared for subgroups based on residency program affiliation and residency characteristics. Out of 262 eligible residents, 124 completed the survey (response rate 47%). The overall mean score was 3.89 (standard deviation=0.56). The initial reliability analysis of the 48-item scale had a high reliability coefficient (Cronbach α=.94). Factor analysis and further item analysis resulted in a shorter 36-item scale with a satisfactory reliability coefficient (Cronbach α=.86). Scores were higher for residents with prior EBM training in medical school (4.14 versus 3.62) and in residency (4.25 versus 3.69). If further testing confirms its properties, the EBM Environment Scale may be used to understand the influence of the learning environment on the effectiveness of EBM training. Additionally, it may detect changes in the EBM learning environment in response to programmatic or institutional interventions.

Modelling the relationship between soil color and particle size for soil survey in Ferralsol environments

Full Text Available Soil texture is an important property for evaluating its inherent fertility especially by using pedo-transfers functions requiring particle size data. However, there is no existing quantitative method for in situ estimation of soil particle size, delaying judgement of soil chemical properties in the field. For this purpose, laboratory particle size analyses of 1028 samples from 281 Ferralsol profiles, located between latitudes 7º N and 10º N in Côte d’Ivoire and their respective colour notation by Munsell chart were used to generate prediction models. Multiple Linear Regression Analysis by Group was processed to identify clay, sand and silt contents in the soil based on color hue (2.5YR, 5YR, 7.5YR, and 10YR and Chroma (1, 2, 3, 4, 5, 6, 7, 8. The evaluation was conducted for each horizon coded as H1 (0-20 cm, H2 (20-60 cm, H3 (60-80 cm and H4 (80-150 cm and used as grouping variables. Highly significant (P< 0.001 models were identified for clay and sand. These models were used to estimate successfully clay and sand contents for other Ferralsol samples by comparing calculated and measured mean using the null hypothesis of difference and Tukey’s tests. They were accurate for at all depths, except 80 - 150 cm, for sand in 10YR soils. The method was deemed appropriate for in situ estimation of soil particle size contents in Ferralsol environment for improving reconnaissance agricultural soil surveys.

This paper deals with the environmental problems related to Petroleum Exploration Programs (PEP) in Madagascar and measures taken, in short terms, to minimize environment degradation resulting from these. PEP concerns the three main western sedimentary basins (Ambilobe Basin - Majunga Basin - Morodava basin) of which 12% of the surface are classified as protected area (forests, parks, reserves) in respect of the richness and rareness of wildlife species. PEP's operations (seismic survey and drilling wells), when conducted in these zones, affect the system (access road, people migration), leading to the degradation of the wildlife. For petroleum companies working in those zones, some appropriate measures (adequacy of equipment, engagement to restore damages, environment study) were required before concerned administration could grant the agreement. One example of specific environment damages caused by Petroleum Exploration Operations is mentioned in this paper

Trade-offs can exist within and across environments, and constrain evolutionary trajectories. To examine the effects of competition and resource availability on trade-offs, we grew individuals of recombinant inbred lines of Impatiens capensis in a factorial combination of five densities with two light environments (full light and neutral shade) and used a Bayesian logistic growth analysis to estimate intrinsic growth rates. To estimate across-environment constraints, we developed a variance decomposition approach to principal components analysis, which accounted for sample size, model-fitting, and within-RIL variation prior to eigenanalysis. We detected negative across-environment genetic covariances in intrinsic growth rates, although only under full-light. To evaluate the potential importance of these covariances, we surveyed natural populations of I. capensis to measure the frequency of different density environments across space and time. We combined our empirical estimates of across-environment genetic variance-covariance matrices and frequency of selective environments with hypothetical (yet realistic) selection gradients to project evolutionary responses in multiple density environments. Selection in common environments can lead to correlated responses to selection in rare environments that oppose and counteract direct selection in those rare environments. Our results highlight the importance of considering both the frequency of selective environments and the across-environment genetic covariances in traits simultaneously. © 2010 The Author(s).

To develop, field test and analyse a social capital survey instrument for measuring the nursing work environment. The concept of social capital, which focuses on improving productive capacity by examining relationships and networks, may provide a promising framework to measure and evaluate the nurse work environment in a variety of settings. A survey instrument for measuring social capital in the nurse work environment was developed by adapting the World Bank's Social Capital - Integrated Questionnaire (SC-IQ). Exploratory factor analysis and multiple regression analyses were applied to assess the properties of the instrument. The exploratory factor analysis yielded five factors that align well with the social capital framework, while reflecting unique aspects of the nurse work environment. The results suggest that the social capital framework provides a promising context to assess the nurse work environment. Further work is needed to refine the instrument for a diverse range of health-care providers and to correlate social capital measures with quality of patient care. Social capital measurement of the nurse work environment has the potential to provide managers with an enhanced set of tools for building productive capacity in health-care organisations and achieving desired outcomes. © 2013 John Wiley & Sons Ltd.

Survey Harmonisation with New Technologies Improvement (SHANTI)

The transport sector is one of the major sources of global warming, both from individual travel behaviour (especially car use) and from freight transport (mainly by trucks). Mobility surveys, as well as data collections about travel behaviour, are essential to develop transportation policies...... and measures which encourage more environment-friendly transport modes. Data quality is a real challenge, mainly because response rates are declining and interviewees are more and more reluctant to respond to burdensome questionnaires. Furthermore, harmonized data are a must for authorities, but in Europe...... and positioning technologies including GPS/GALILEO, GSM and Radio Data System (RDS) have advanced rapidly and their costs are decreasing. They demonstrate great potential as survey instruments for tracking individual mobility and travel behaviour as well as freight movements, by enabling to conduct surveys along...

Preclinical Medical Student Hematology/Oncology Education Environment.

2015-12-01

To better prepare medical students to care for patients in today's changing health-care environment as they transition to continuing their education as residents, many US medical schools have been reviewing and modifying their curricula and are considering integration of newer adult learning techniques, including team-based learning, flipped classrooms, and other active learning approaches (Assoc Am Med Coll. 2014). Directors of hematology/oncology (H/O) courses requested an assessment of today's H/O education environment to help them respond to the ongoing changes in the education content and environment that will be necessary to meet this goal. Several recommendations for the improvement of cancer education resulted from American Association for Cancer Education's (ACCE's) "Cancer Education Survey II" including a call for medical schools to evaluate the effectiveness of current teaching methods in achieving cancer education objectives (Chamberlain et al. J Cancer Educ 7(2):105-114.2014). To understand the current environment and resources used in medical student preclinical H/O courses, an Internet-based, Survey Monkey®-formatted, questionnaire focusing on nine topic areas was distributed to 130 United States Hematology/Oncology Course Directors (HOCDs). HOCDs represent a diverse group of individuals who work in variably supportive environments and who are variably satisfied with their position. Several aspects of these courses remain relatively unchanged from previous assessments, including a predominance of traditional lectures, small group sessions, and examinations that are either written or computer-based. Newer technology, including web-based reproduction of lectures, virtual microscopes, and availability of additional web-based content has been introduced into these courses. A variety of learner evaluation and course assessment approaches are used. The ultimate effectiveness and impact of these changes needs to be determined.

Associations between baccalaureate nursing students' perceptions of educational environment and HESI scores and GPA.

Students' perceptions of their educational environment have been found to be related to their approaches to learning and learning outcomes. Educational environment is just beginning to be researched in nursing education with the vast majority of studies focusing on the clinical educational environment. Perception of educational environment has been shown to influence student implementation of a specific learning style and influences educational outcomes such as program completion and GPA. There is a need for sound research that explores the relationship, if any, between perceptions of environment and outcomes. To explore the relationship between baccalaureate nursing student (BSN) perception of educational environment (SPEE) and objective learning outcomes. Retrospective correlational descriptive study. Private School of Nursing in the Southwest. Convenience sample of 62 graduating baccalaureate students. All graduating BSN students were invited to complete the Dundee Ready Education Environment Measure (DREEM) through the online survey application Qualtrics. A total of 62 students completed the DREEM survey. These results were compared with each student's GPA and HESI score. A total of 62 students completed the survey for an overall response rate of 57%. There was no correlation between total SPEE and nursing grade point average (NGPA) or HESI exit scores. Based on this study at this institution, it appears that students' performance was not influenced by SPEE. One of the major implications of this study is the possibility that an "acceptable" SPEE (one that is neither exceptional nor terrible) may not significantly influence student outcomes. Exploring this relationship has theoretical as well as practical implications as educators seek to determine the effectiveness of educational interventions. Student perception of learning environment is measured in various ways at the majority of institutions. It has been assumed that an educational environment that is

The purpose of this study was to assess the work environment as perceived by nurses in a large tertiary hospital in Saudi Arabia. The quality of patient care services has been associated with the quality of work environment of nurses. It is therefore important to assess the work environment in order to acquire baseline data and enable the institution to benchmark their status from established quality standards. This study used a descriptive survey with 1007 staff nurses across service units of a 1000-bed government-operated hospital. The American Association of Critical-Care Nurses (AACN) Healthy Work Environment Assessment Questionnaire was used for data collection. Scores were aggregated and interpreted. Effective decision making, authentic leadership, appropriate staffing, true collaboration, skilled communication and meaningful recognition were rated as good (mean range 3.53-3.76). Healthy work environments mutually benefit patients, nurses, nurse managers, health care providers, the health team, administration, the institution and the community at large. Valuable baseline data on the status of the work environment in this setting were generated. This should allow administrators and staff to work together in improving weaknesses and strengthening further whatever gains that are attained to ensure consistent provision of safe and quality patient care. © 2013 John Wiley & Sons Ltd.

The Sloan Digital Sky Survey-II Supernova Survey has identified a large number of new transient sources in a 300 deg{sup 2} region along the celestial equator during its first two seasons of a three-season campaign. Multi-band (ugriz) light curves were measured for most of the sources, which include solar system objects, galactic variable stars, active galactic nuclei, supernovae (SNe), and other astronomical transients. The imaging survey is augmented by an extensive spectroscopic follow-up program to identify SNe, measure their redshifts, and study the physical conditions of the explosions and their environment through spectroscopic diagnostics. During the survey, light curves are rapidly evaluated to provide an initial photometric type of the SNe, and a selected sample of sources are targeted for spectroscopic observations. In the first two seasons, 476 sources were selected for spectroscopic observations, of which 403 were identified as SNe. For the type Ia SNe, the main driver for the survey, our photometric typing and targeting efficiency is 90%. Only 6% of the photometric SN Ia candidates were spectroscopically classified as non-SN Ia instead, and the remaining 4% resulted in low signal-to-noise, unclassified spectra. This paper describes the search algorithm and the software, and the real-time processing of the SDSS imaging data. We also present the details of the supernova candidate selection procedures and strategies for follow-up spectroscopic and imaging observations of the discovered sources.

Many restaurants have smooth rigid surfaces made of wood, steel, glass, and concrete. This often results in a lack of sound absorption. Such restaurants are notorious for high sound noise levels during service that most owners actually desire for representing vibrant eating environments, although...... surveys report that noise complaints are on par with poor service. This study investigated the relation between objective acoustic parameters and subjective evaluation of acoustic comfort at five restaurants in terms of three parameters: noise annoyance, speech intelligibility, and privacy. At each...... location, customers filled out questionnaire surveys, acoustic parameters were measured, and recordings of restaurant acoustic scenes were obtained with a 64-channel spherical array. The acoustic scenes were reproduced in a virtual sound environment (VSE) with 64 loudspeakers placed in an anechoic room...

Small- and medium-sized enterprises (SMEs) generate nearly 80% of the jobs in China, but the dangerous work environment often found in these enterprises poses a major concern for public health. Psychosocial pressure and mental health problems among the workers are also common in SMEs. However, mental health of workers in SMEs is largely neglected in occupational health research and practice in China. The purpose of this study is to assess mental health of the workers and to explore the associations between physical and psychosocial work environment and workers' mental health in SMEs in South China. Data were collected in 2012 through a cross-sectional survey among 1200 workers working in small- and medium-sized enterprises (SMEs) in Guangdong, China. Mental health was measured by psychological well-being in the current study. Job Demand-Control-Support (JDCS) model was used as a theoretical framework to examine the psychosocial factors associated with workers' psychological well-being. Data were analyzed using SPSS 20.0 and analysis was performed using bivariate analyses and multivariate logistic regression. About three in ten workers (35.3%) in the sample had poor psychological well-being. Those who were men, younger in age, or migrant workers had worse psychological outcome in bivariate analyses. After controlling for individual variables (gender, age, marital status, and household registration), we found that longer weekly work hours (OR = 1.30, 95% CI: 1.13 ~ 1.50), more exposure to hazardous work environment (OR = 1.26, 95% CI: 1.10 ~ 1.44), higher job demands (OR = 1.29, 95% CI: 1.12 ~ 1.49), and lower job autonomy (OR = 0.70, 95% CI: 0.60 ~ 0.81) were significant associated with worse psychological well-being. The results were consistent with predictions of the JDCS model. The results indicate that the JDCS model is a useful framework in predicting psychological well-being among Chinese workers in SMEs. Future mental health promotion should focus on young

Unhealthy diets are heavily driven by unhealthy food environments. The International Network for Food and Obesity/non-communicable diseases (NCDs) Research, Monitoring and Action Support (INFORMAS) has been established to reduce obesity, NCDs and their related inequalities globally. This paper describes the design and methods of the first-ever, comprehensive national survey on the healthiness of food environments and the public and private sector policies influencing them, as a first step towards global monitoring of food environments and policies. A package of 11 substudies has been identified: (1) food composition, labelling and promotion on food packages; (2) food prices, shelf space and placement of foods in different outlets (mainly supermarkets); (3) food provision in schools/early childhood education (ECE) services and outdoor food promotion around schools/ECE services; (4) density of and proximity to food outlets in communities; food promotion to children via (5) television, (6) magazines, (7) sport club sponsorships, and (8) internet and social media; (9) analysis of the impact of trade and investment agreements on food environments; (10) government policies and actions; and (11) private sector actions and practices. For the substudies on food prices, provision, promotion and retail, 'environmental equity' indicators have been developed to check progress towards reducing diet-related health inequalities. Indicators for these modules will be assessed by tertiles of area deprivation index or school deciles. International 'best practice benchmarks' will be identified, against which to compare progress of countries on improving the healthiness of their food environments and policies. This research is highly original due to the very 'upstream' approach being taken and its direct policy relevance. The detailed protocols will be offered to and adapted for countries of varying size and income in order to establish INFORMAS globally as a new monitoring initiative

For active environment technology export to OECD countries, needs for environmental measures in developing countries were surveyed. Both collection of environment technology needs in developing countries and preparation of technology seeds information of Japanese enterprises, and promotion of environmental projects by adding an information dispatch function are important. Active preparation and exchange of experiences and know-how of concerned enterprises, local governments and national organizations are also necessary. For development and possible export of small- and medium-sized ventures with excellent technologies and know-how, a suitable consulting system is essential for risks. For smooth promotion of warming prevention by international cooperation, active development of monitoring technology is also important. To support developing countries, OJT of persons in charge in technology transfer sites, and preparation of information infrastructure are necessary. Japan with much know-how on environmental preservation should positively participate in international standardization activities such as ISO. 10 refs., 14 figs., 56 tabs.

A survey of simultaneous localization and mapping on unstructured lunar complex environment

2017-10-01

Simultaneous localization and mapping (SLAM) technology is the key to realizing lunar rover's intelligent perception and autonomous navigation. It embodies the autonomous ability of mobile robot, and has attracted plenty of concerns of researchers in the past thirty years. Visual sensors are meaningful to SLAM research because they can provide a wealth of information. Visual SLAM uses merely images as external information to estimate the location of the robot and construct the environment map. Nowadays, SLAM technology still has problems when applied in large-scale, unstructured and complex environment. Based on the latest technology in the field of visual SLAM, this paper investigates and summarizes the SLAM technology using in the unstructured complex environment of lunar surface. In particular, we focus on summarizing and comparing the detection and matching of features of SIFT, SURF and ORB, in the meanwhile discussing their advantages and disadvantages. We have analyzed the three main methods: SLAM Based on Extended Kalman Filter, SLAM Based on Particle Filter and SLAM Based on Graph Optimization (EKF-SLAM, PF-SLAM and Graph-based SLAM). Finally, this article summarizes and discusses the key scientific and technical difficulties in the lunar context that Visual SLAM faces. At the same time, we have explored the frontier issues such as multi-sensor fusion SLAM and multi-robot cooperative SLAM technology.

2009-09-01

To examine availability and accessibility of public computing for individuals with cognitive impairment (CI) who reside in the USA. A telephone survey was administered as a semi-structured interview to 145 informants representing seven types of public facilities across three geographically distinct regions using a snowball sampling technique. An Internet search of wireless (Wi-Fi) hotspots supplemented the survey. Survey results showed the availability of public computer terminals and Internet hotspots was greatest in the urban sample, followed by the mid-sized and rural cities. Across seven facility types surveyed, libraries had the highest percentage of access barriers, including complex queue procedures, login and password requirements, and limited technical support. University assistive technology centres and facilities with a restricted user policy, such as brain injury centres, had the lowest incidence of access barriers. Findings suggest optimal outcomes for people with CI will result from a careful match of technology and the user that takes into account potential barriers and opportunities to computing in an individual's preferred public environments. Trends in public computing, including the emergence of widespread Wi-Fi and limited access to terminals that permit auto-launch applications, should guide development of technology designed for use in public computing environments.

2014-10-01

An important goal of home health care is to assist patients to remain in community living arrangements. Yet home care often fails to prevent hospitalizations and to facilitate discharges to community living, thus putting patients at risk of additional health challenges and increasing care costs. To determine the relationship between home health agency work environments and agency-level rates of acute hospitalization and discharges to community living. Analysis of linked Center for Medicare and Medicaid Services Home Health Compare data and nurse survey data from 118 home health agencies. Robust regression models were used to estimate the effect of work environment ratings on between-agency variation in rates of acute hospitalization and community discharge. Home health agencies with good work environments had lower rates of acute hospitalizations and higher rates of patient discharges to community living arrangements compared with home health agencies with poor work environments. Improved work environments in home health agencies hold promise for optimizing patient outcomes and reducing use of expensive hospital and institutional care.

The purpose of this study was to determine the immediate effects of cognitive training on healthy older adults and verify the transfer effects of targeted and non-targeted abilities. The design consisted of a semi-randomized clinical controlled trial. The final sample was composed of 80 volunteers recruited from a Brazilian community (mean age = 69.69; SD = 7.44), which were separated into an intervention group (N = 47; mean age = 69.66, SD = 7.51) and a control group (N = 33; mean age = 69.73, SD = 7.45). Intervention was characterized by adaptive cognitive training with 12 individual training sessions of 60 to 90 minutes (once a week). Eight instruments were used to assess effects of cognitive training. Five were used to assess trained abilities (near effects), including: Memorization Tests (List and History), Picture Completion, Digit Span, Digit Symbol-Coding, and Symbol Search (the last four from WAIS-III). Two instruments assessed untrained abilities (far effects): Arithmetic and Matrix Reasoning (WAIS-III). The non-parametric repeated measures ANOVA test revealed a significant interaction between group by time interaction for Picture Completion [F(74) = 14.88, p = .0002, d = 0.90, CLES = 73.69%], Digit Symbol-Coding [F(74) = 5.66, p = .019, d = 0.55, CLES = 65.21%] and Digit Span [F(74) = 5.38, p = .02, d = 0.54, CLES = 64.85%], suggesting an interventional impact on these performance tasks. The results supported near transfer effects, but did not demonstrate a far transfer effects.

Full Text Available Background : The learning environment of a medical school has a significant impact on students’ achievements and learning outcomes. The importance of equitable learning environments across programme sites is implicit in distributed undergraduate medical programmes being developed and implemented. Purpose : To study the learning environment and its equity across two classes and three geographically separate sites of a distributed medical programme at the University of British Columbia Medical School that commenced in 2004. Method : The validated Dundee Ready Educational Environment Survey was sent to all students in their 2nd and 3rd year (classes graduating in 2009 and 2008 of the programme. The domains of the learning environment surveyed were: students’ perceptions of learning, students’ perceptions of teachers, students’ academic self-perceptions, students’ perceptions of the atmosphere, and students’ social self-perceptions. Mean scores, frequency distribution of responses, and inter- and intrasite differences were calculated. Results : The perception of the global learning environment at all sites was more positive than negative. It was characterised by a strongly positive perception of teachers. The work load and emphasis on factual learning were perceived negatively. Intersite differences within domains of the learning environment were more evident in the pioneer class (2008 of the programme. Intersite differences consistent across classes were largely related to on-site support for students. Conclusions : Shared strengths and weaknesses in the learning environment at UBC sites were evident in areas that were managed by the parent institution, such as the attributes of shared faculty and curriculum. A greater divergence in the perception of the learning environment was found in domains dependent on local arrangements and social factors that are less amenable to central regulation.

Full Text Available Abstract Background Maternal mortality in Sub-Saharan Africa remains a challenge with estimates exceeding 1,000 maternal deaths per 100,000 live births in some countries. Successful prevention of maternal deaths hinges on adequate and quality emergency obstetric care. In addition to skilled personnel, there is need for a supportive environment in terms of essential drugs and supplies, equipment, and a referral system. Many household surveys report a reasonably high proportion of women delivering in health facilities. However, the quality and adequacy of facilities and personnel are often not assessed. The three delay model; 1 delay in making the decision to seek care; 2 delay in reaching an appropriate obstetric facility; and 3 delay in receiving appropriate care once at the facility guided this project. This paper examines aspects of the third delay by assessing quality of emergency obstetric care in terms of staffing, skills equipment and supplies. Methods We used data from a survey of 25 maternity health facilities within or near two slums in Nairobi that were mentioned by women in a household survey as places that they delivered. Ethical clearance was obtained from the Kenya Medical Research Institute. Permission was also sought from the Ministry of Health and the Medical Officer of Health. Data collection included interviews with the staff in-charge of maternity wards using structured questionnaires. We collected information on staffing levels, obstetric procedures performed, availability of equipment and supplies, referral system and health management information system. Results Out of the 25 health facilities, only two met the criteria for comprehensive emergency obstetric care (both located outside the two slums while the others provided less than basic emergency obstetric care. Lack of obstetric skills, equipment, and supplies hamper many facilities from providing lifesaving emergency obstetric procedures. Accurate estimation of burden

Little is known about specific personal and professional factors influencing student distress. The authors conducted a comprehensive assessment of how learning environment, clinical rotation factors, workload, demographics and personal life events relate to student burnout. All medical students (n = 3080) at five medical schools were surveyed in the spring of 2006 using a validated instrument to assess burnout. Students were also asked about the aforementioned factors. A total of 1701 medical students (response rate 55%) completed the survey. Learning climate factors were associated with student burnout on univariate analysis (odds ratio [OR] 1.36-2.07; all P burnout (ORs 1.69 and 1.48, respectively; both P student burnout. Students who experienced a positive personal life event had a lower frequency of burnout (OR 0.70; P burnout than students who did not experience a negative personal life event. On multivariate analysis personal characteristics, learning environment and personal life events were all independently related to student burnout. Although a complex array of personal and professional factors influence student well-being, student satisfaction with specific characteristics of the learning environment appears to be a critical factor. Studies determining how to create a learning environment that cultivates student well-being are needed.

2015-01-01

Background Evidence-based interventions (EBIs) have the potential to maximize positive impact on communities. However, despite the quantity and quality of EBIs for prevention, the need for formalized training and associated training-related expenses, such as travel costs, program materials, and input of personnel hours, pose implementation challenges for many community-based organizations. In this study, the community of inquiry (CoI) framework was used to develop the virtual learning environment to support the adaptation of the ¡Cuídate! (Take Care of Yourself!) Training of Facilitators curriculum (an EBI) to train facilitators from community-based organizations. Objective The purpose of this study was to examine the feasibility of adapting a traditional face-to-face facilitator training program for ¡Cuídate!, a sexual risk reduction EBI for Latino youth, for use in a multi-user virtual environment (MUVE). Additionally, two aims of the study were explored: the acceptability of the facilitator training and the level of the facilitators’ knowledge and self-efficacy to implement the training. Methods A total of 35 facilitators were trained in the virtual environment. We evaluated the facilitators' experience in the virtual training environment and determined if the learning environment was acceptable and supported the acquisition of learning outcomes. To this end, the facilitators were surveyed using a modified community of inquiry survey, with questions specific to the Second Life environment and an open-ended questionnaire. In addition, a comparison to face-to-face training was conducted using survey methods. Results Results of the community of inquiry survey demonstrated a subscale mean of 23.11 (SD 4.12) out of a possible 30 on social presence, a subscale mean of 8.74 (SD 1.01) out of a possible 10 on teaching presence, and a subscale mean of 16.69 (SD 1.97) out of a possible 20 on cognitive presence. The comparison to face-to-face training showed no

Mobile autonomous robot for radiological surveys

International Nuclear Information System (INIS)

Dudar, A.M.; Wagner, D.G.; Teese, G.D.

1992-01-01

The robotics development group at the Savannah River Laboratory (SRL) is developing a mobile autonomous robot that performs radiological surveys of potentially contaminated floors. The robot is called SIMON, which stands for Semi-Intelligent Mobile Observing Navigator. Certain areas of SRL are classified as radiologically controlled areas (RCAs). In an RCA, radioactive materials are frequently handled by workers, and thus, the potential for contamination is ever present. Current methods used for floor radiological surveying includes labor-intensive manual scanning or random smearing of certain floor locations. An autonomous robot such as SIMON performs the surveying task in a much more efficient manner and will track down contamination before it is contacted by humans. SIMON scans floors at a speed of 1 in./s and stops and alarms upon encountering contamination. Its environment is well defined, consisting of smooth building floors with wide corridors. The kind of contaminations that SIMON is capable of detecting are alpha and beta-gamma. The contamination levels of interest are low to moderate

The paper grasped the state of coal utilization by coal consumption field, the state of coal physical flow in Vietnam, etc., surveyed/studied a possibility of introducing the environment friendly type coal utilization system, and assessed the possibility. As to energy resources, the north is abundant in hydroelectric and coal (mainly anthracite) resources, and the south in oil and natural gas resources. Coal production in fiscal 1997 is planned to be 10 million tons. Coal preparation technique presently available is only grain size sieving. Accordingly, it is necessary to study for heightening efficiency of facilities and modernizing facilities in accordance with the introduction of the environment friendly type coal utilization technology. During the study, it is possible to propose improvement on coal processing technology (coal preparation technology). Assessment and study are made especially of the coal selection system, fine coal recovery system and waste water treatment system. For the plan on new coal-fired power plants (300MWtimes4), there is left much necessity of proposing studying models considered of the anthracite combustion technology and environmental improvement and of assessing/studying them. 60 figs., 117 tabs.

The nursing practice environment is an important factor for services to consider in the attraction and retention of a skilled workforce during future nursing shortages. Despite the significant number of international studies undertaken to understand the influence of the practice environment on nurse satisfaction and retention, few have been undertaken within the mental health setting. This paper reports on results from a survey conducted in a large Australian public mental health hospital to examine nurses' perceptions of their practice environment, and identifies interventions that could be implemented to improve the practice environment. The hospital is the only remaining, standalone public mental health hospital in Western Australia. © 2016 Australian College of Mental Health Nurses Inc.

We have conducted a detailed multi-wavelength investigation of a variety of massive star forming regions in order to characterise the impact of the interactions between the substructure of the dense protostellar clumps and their local environment, including feedback from the embedded proto-cluster.A selection of 70 MYSOs and HII regions identified by the RMS survey have been followed up with observations of the ammonia (1,1) and (2,2) inversion transitions made with the KFPA on the GBT. These maps have been combined with archival CO data to investigate the thermal and kinematic structure of the extended envelopes down to the dense clumps. We complement this larger-scale picture with high resolution near- and mid-infrared images to probe the properties of the embedded objects themselves.We present an overview of several sources from this sample that illustrate some of the the interactions that we observe. We find that high molecular column densities and kinetic temperatures are coincident with embedded sources and with shocks and outflows as exhibited in gas kinematics.

A humanistic environment for dental schools: what are dental students experiencing?

Science.gov (United States)

Quick, Karin K

2014-12-01

A Commission on Dental Accreditation (CODA) standard now requires that dental schools commit to establishing a "humanistic culture and learning environment" for all members of the academic environment. The aim of this study was to identify students' perceptions of factors that affect the dental school environment and to test differences in their experiences in terms of gender and year. This picture of the existing environment was meant to serve as a first step toward creating and supporting a more humanistic academic environment. A mixed-methods approach was used for data collection during the 2009-10 and 2010-11 academic years at one U.S. dental school. Four focus groups were first conducted to explore challenges and conflicts faced by students during their dental education. A written survey informed by the focus group results was then used to obtain quantitative data. The survey response rate was 47 percent (N=188). Faculty inconsistency, cheating, and belittlement/disrespect were experienced by many of the responding dental students during their education, similar to what has been documented in medicine. These students also reported experiencing both constructive communication (90 percent) and destructive communication (up to 32 percent). The female students reported more gender discrimination and sexual harassment than their male peers, and the clinical students reported more experience with belittlement and destructive communication than the preclinical students. The results suggest that greater effort should be directed toward creating a more humanistic environment in dental schools. Based on the issues identified, steps academic institutions can take to improve these environments and student skills are outlined.

The relationship between the school environment and health has infrequently been examined. This study sought to examine the association between school students' perceptions of their school environment, teachers' and peers' support and their health behaviours. A cross sectional descriptive survey by supervised self-administration was conducted in 1996 based on the international WHO collaborative survey of school children's health and lifestyle (the HBSC Study) and extended in an Australian setting. Randomly sampled primary and secondary schools from Catholic, Independent and Government education sectors throughout New South Wales (NSW), Australia, were invited to participate. The final sample included 3918 school students attending Year 6 (primary school), Year 8 and Year 10 (high school) from 115 schools. The main outcome measures were self-reported health status and 7 health behaviours (tobacco use, alcohol use, physical activity, dental hygiene, nutritional intake, seat belt and bicycle helmet use). Independent variables included student perceptions of the school environment, perceptions of teachers' and peers' support. Girls, Year 6 students and students who have less than $19 a week to spend were significantly more likely to have positive perceptions towards their school environment, teacher(s) and peers. Students who had positive perceptions regarding their school environment and perceived their teachers as supportive were significantly more likely to engage in health promoting behaviours adjusting for age, sex and average weekly pocket money. A supportive peer environment was not associated with positive health behaviour. Health promotion practitioners need to consider the impact of the school environment on health behaviours of school students. In particular, practitioners should consider intervention models that improve the school environment as a key strategy within a health promoting school.

To examine possible associations between perceived neighborhood environments and obesity among a U.S. nationally representative sample of Afro-Caribbean, African American, and Non-Hispanic white adults. Data was used from the 2001-2003 National Survey of American Life (NSAL). All measures including neighborhood characteristics, height, and weight were self-reported. Multivariate logistic regression was used to compute odds ratios (ORs) of obesity (body mass index (BMI) ≥ 30 kg/m(2)) based on perceived neighborhood physical and social characteristics. The odds of obesity were significantly lower for adults who reported involvement in clubs, associations, or help groups (odds ratio (OR): 0.62; 95% confidence interval (CI): 0.44, 0.85) and perceived that they had a park, playground, or open space in their neighborhood (odds ratio (OR): 0.68; 95% confidence interval (CI): 0.47, 0.98). These associations remained significant after adjusting for leisure-time physical activity. Race/ethnicity appeared to modify the association between involvement in clubs, associations, or help groups and obesity. Providing parks, playgrounds, or open space or increasing the perception of those amenities may assist in the prevention of obesity, especially in ethnically diverse neighborhoods in the United States. More research is needed to investigate how perceptions of the neighborhood environment influence obesity and whether perceptions of the neighborhood environment differ between individuals within the same neighborhoods.

Wen, F.; Wu, F.F.

2005-01-01

This paper is the second half of a 2-part paper that provided details of a comprehensive survey of issues related to transmission investment and expansion planning in the electricity market. Results of the survey suggested that transmission regulation is needed to provide a fair playing field for competition and to ensure that transmission networks are optimally expanded while also meeting reliability constraints. Regulations will create further incentives for cost reduction while ensuring that regulated firms have assurance of cost recovery. Transmission planning should be controlled or monitored by a government organization or regulator. Legislation is needed to ensure that regulatory authorities can enforce reliability criteria. Mandatory reliability standards and metrics for reliability services should be implemented. The economic benefits of transmission expansion in a deregulated market should be modelled using non-deterministic approaches. It was concluded that transmission expansion plans should be able to meet future transmission capacity requirements, secure returns on investment, and ensure reliability levels for customers. Various international transmission expansion plans were also provided. 38 refs

The results of public opinion surveys were used to assess the variation in views and attitudes toward the environment among different social strata in several countries. The developed countries have recently become concerned about the disappearance of the rain forests, but mere survival is more of a preoccupation for the majority of Brazilians than damage tot he rain forest. A survey of a representative national sample during the 1989 presidential election indicated that fewer than 10% of Brazilians considered ecological problems among the 3 major national problems. But in a survey to determine which environmental problems in Brazil were considered most serious, burning of the tropical forest was identified by the greatest proportion of respondents, 19%, followed by industrial pollution of rivers and cities, 17%. Surveys in 1990-91 in Great Britain indicated in contrast that some 92% of respondents were in favor of 1 or more measures to limit deterioration of the tropical forest, such as limiting importation of wood from countries not protecting their forests or contributing funds to ecological groups. Opinion surveys in British Columbia, whose main economic activity is forestry, showed that 40% of respondents considered ecological problems to be the most serious, ahead of unemployment, the economy, or social services. But specific questions on clear cutting of forests, preservation of old forest in Vancouver, or pollution controls for the paper industry, which closely affected the local economy, divided opinion and probably demonstrated a desire to protect the environment without too greatly disturbing the local economy. Study of the reactions of developing country populations to environmental problems is difficult because of language and cultural barriers, political instability, war, natural catastrophes, and difficulty of establishing representative samples, among other factors.

This survey of environmental effect was intended to grasp actual state concerning some environmental factors that should agree with survey/development and also to assess its effect on the surrounding environment, particularly as a part of the 'stage C' in the 'survey for geothermal development and promotion', which was implemented by the Government for the purpose of guiding geothermal development by enterprises. This report compiles the plan details of the environmental effect survey to be conducted in the Hakusuigoe district, and presents proposals. The survey area is in the north of Makizono-cho, Aira-gun, in Kagoshima prefecture and situated about 3 km west of Onaminoike in Karakunidake, one of the peaks in the Kirishima mountain range. The Ogiri geothermal power plant is in the west of the site, a tourist spot Ebino Heights about 4 km northeast, and the Kirishima hot-spring about 4 km southeast. The location is in the national park, with a part designated as No. 2 and 3 class special areas. The environmental effect survey was divided broadly into such categories as fauna/flora, hot-spring water alteration and inland water, landscape, noise/vibration/subsoil, and air/water, and was further subdivided in accordance with the actual operations.

Consumer nutrition environment measures are important to understanding the food environment, which affects individual dietary intake. A nutrition environment measures survey for supermarkets (NEMS-S) has been designed on paper for use in Guatemala. However, a paper survey is not an inconspicuous data collection method. To design, pilot test, and validate the Guatemala NEMS-S in the form of a mobile phone application (mobile app). CommCare, a free and open-source software application, was used to design the NEMS-S for Guatemala in the form of a mobile app. Two raters tested the mobile app in a single Guatemalan supermarket. Both the interrater and the test-retest reliability of the mobile app were determined using percent agreement and Cohen's kappa score and compared with the interrater and test-retest reliability of the paper version. Interrater reliability was very high between the paper survey and the mobile app (Cohen's kappa > 0.90). Test-retest reliability ranged from kappa 0.78 to 0.91. Between two certified NEMS-S raters, survey completion time using the mobile app was 5 minutes less than that with the paper form (35 vs. 40 minutes). The NEMS-S mobile app provides for more rapid data collection, with equivalent reliability and validity to the NEMS-S paper version, with advantages over a paper-based survey of multiple language capability and concomitant data entry.

Survey on food consumption

Critical pathway approach is one of the methods for estimating discharge limits of radioactive nuclides into an environment. In connection with this it is presented that a term of 'critical group' is in danger of leading to the misunderstanding of 'dangerous group'. However, in fact, the present discharge is limited to a level as low as practicable. Therefore, on the evaluation of intermal radiation dose for such a low release, a term of 'reference group' should be recommended instead of critical group. In order to select reasonably 'the reference group', it was proposed to calculate 'effective whole body dose-equivalent limit', which was recommended by ICRP publication 26. It is a convenient method to sum up individual weighed dose of each critical organ by using the value of a ratio obtained from Wt as a weighing factor. Finally instructions for the survey on food consumption and the results were summarized on the basis of ten-years survey experiences in coastal area of Ibaraki prefecture. (author)

Théâtre de masques : allégories et déguisements sur la scène comique française des XVe et XVIe siècles.

Full Text Available Résumé : Sur la scène comique française des XVe et XVIe siècles abondent masques et déguisements. Tous les acteurs n’en sont pas pourtant revêtus et le sens du costume change selon l’identité du personnage, notamment dans le conflit qui, dans les sotties ou les moralités, opposent Sots et allégories. Le port du masque désigne le Sot et sa parole dénonciatrice : le « faux visage » est, paradoxalement, gage de liberté. Mais lorsque les allégories se déguisent, c’est le fonctionnement de la figure qui est mis en jeu : celle dont l’apparence était l’essence ne peut normalement porter le masque. Les divers types de relations entre l’allégorie et le déguisement créent sur scène une confusion comique autant qu’inquiétante, qui est souvent le moteur de l’action. Les relations au masque des divers personnages de théâtre sont une voie d’analyse pour mieux comprendre une époque majeure de la réflexion sur la représentation et sur les tensions entre apparence et essence.Abstract : Masks in Drama : Allegory and Costume on the French Comic Stage (15th-16th c.. In French comic theatre of the 15th and 16th centuries, masks are commonplace. However, they are worn only by specific figures, and dress changes its meaning from one character to another, especially in the conflict between Fools and allegories in morality plays or sotties. Wearing a mask marks out the Fool and his provocative speech : paradoxically, a ‘false face’ means freedom of expression. But when allegories put on disguises, the very trope of allegory is threatened : its essence lies in appearance, and therefore precludes the use of masks. The different ways in which allegory can be ‘disguised’ on stage provoke comic and often disturbing confusions, which often drive the action. The links between mask and character provide an important approach to the problem of representation in a period which saw considerable reflection on this

In the process of selecting a safe and environmentally acceptable location for the deep level repository of nuclear waste, site surveys will be carried out. These site surveys will also include studies of the biota at the site, in order to assure that the chosen site will not conflict with important ecological interests, and to establish a thorough baseline for future impact assessments and monitoring programmes. As a preparation to the site survey programme, a review of the variables that need to be surveyed is conducted. This report contains the review for some of those variables. For each variable, existing data sources and their characteristics are listed. For those variables for which existing data sources are inadequate, suggestions are made for appropriate methods that will enable the establishment of an acceptable baseline. In this report the following variables are reviewed: Fishery, Landscape, Vegetation types, Key biotopes, Species (flora and fauna), Red-listed species (flora and fauna), Biomass (flora and fauna), Water level, water retention time (incl. water body and flow), Nutrients/toxins, Oxygen concentration, Layering, stratification, Light conditions/transparency, Temperature, Sediment transport, (Marine environments are excluded from this review). For a major part of the variables, the existing data coverage is most likely insufficient. Both the temporal and/or the geographical resolution is often limited, which means that complementary surveys must be performed during (or before) the site surveys. It is, however, in general difficult to make exact judgements on the extent of existing data, and also to give suggestions for relevant methods to use in the site surveys. This can be finally decided only when the locations for the sites are decided upon. The relevance of the different variables also depends on the environmental characteristics of the sites. Therefore, we suggest that when the survey sites are selected, an additional review is

There are few well-designed studies of corrections or prison nursing roles. This study seeks to describe the corrections or prison role of forensic nurses in the United States who provide care in secure environments. National data detailing the scope of practice in secure environments are limited. This pencil and paper survey describes the roles of 180 forensic nurses from 14 states who work in secure environments. Descriptive statistics are utilized. A repeated measures ANOVA with post hoc analyses was implemented. These nurses were older than average in age, but had 10 years or less experience in forensic nursing practice. Two significant roles emerged to "promote and implement principles that underpin effective quality and practice" and to "assess, develop, implement, and improve programs of care for individuals." Significant roles varied based upon the security classification of the unit or institution in which the nurses were employed. Access to information about these nurses and their nursing practice was difficult in these closed systems. Minimal data are available nationally, indicating a need for collection of additional data over time to examine changes in role. It is through such developments that forensic nursing provided in secure environments will define its specialization and attract the attention it deserves.

Social Representations of the Environment in Press Media

Full Text Available Environmental issues are given prominence in the media and scientific circles. From the 60’s until early 2010 there were changes in the way people related to the environment, with a paradigm shift occurring regarding the environment. This study sought to identify the representational content disseminated by the press media on the environment in different periods. A qualitative survey was therefore conducted of documents, and data were obtained through texts published in a magazine with national circulation. The data were analyzed using the ALCESTE program with a Lexicographic Analysis. It was identified that the press media reflects the paradigm shifts, and publications dating from the late 60’s are compatible with the old paradigm, evolving over time, and are now compatible with the new environmental paradigm. The results indicate that currently the environment needs care in all its aspects and lack of care creates global impacts.

Full Text Available Background: At many Polish hospitals, insufficient attention is given to positive work environment. In many cases nurses, similarly to the representatives of other professional groups, are not provided with facilities or tools to perform their professional tasks in safe conditions. The aspects of recruitment and retention of employees are often ignored. The aim of this study has been to assess the chosen determinants of work environment of nurses in Poland using the concept of the Positive Practice Environments (PPE. Material and Methods: The survey was carried out from 2008 to 2011 among 1049 nursing students of 3 randomly selected public medical universities that provided nursing education at the graduate level of the Master of Science. All the people qualified for the study group were practising nurses or midwives. The Polish Nursing Association coordinated the project, obtained the tool, translated it and adjusted it to the Polish conditions. The areas covered in the survey were: a place of employment, selected physical and social elements influencing the work conditions, and biographical information. Results: Access to as many as 8 factors identified as attributes of friendly environments was found unsatisfactory by over 50% of the nurses. For the purpose of objective assessment, the results were compared with the results obtained in the group of nurses in England. Conclusions: The majority of the surveyed nurses were not satisfied with their work environments. Polish nurse managers should ensure that aspects of recognized attributes of friendly, positive practice environments for nurses are established to support nurses’ satisfaction as a pre-condition for patients’ safety.

Cooperation in energy and environment aspects with developing countries is considered very important in view of the following points: (1) the cooperation will help developing countries to grow economically while minimizing the damages from industrial pollution and environmental problems; (2) conservation of energies and promotion of use of new energies will contribute to solving pollution problems associated with energy production, and will result in assurance of stability of primary energy availability for Japan; (3) preservation of environments in countries exporting foods to Japan will link to maintaining health of Japanese people and increasing their welfare; and (4) Japanese industrial pollution preventing technologies and knowledge whose levels are high worldwide may be utilized to create new business chances for Japanese business entities. The present survey has discussed the importance by territories, the importance by cooperation modes, and sharing of roles by governmental and private organizations, and performed case studies. Considerations were given from the discussion results on how the environmental projects should be planned in the environment cooperation, the contents to be of win/win from the viewpoint of motivation, the project image for subjected territories being composite and comprehensive, and the cases from the viewpoint of mutual coexistence referred to as prevention of global warming and assurance of food and energy resources.

These lecture notes survey the physical processes that give rise to the stray-radiation environment of proton synchrotrons and storage rings, with emphasis on their importance for radiation protection. The origins of the prompt radiation field (which disappears when the accelerator is switched off) are described in some detail: proton-nucleus interactions, extranuclear cascades, muon generation and transport. The effects of induced radioactivity in the accelerator structure and surroundings, notably in iron, concrete, air, and water, are discussed, and methods for monitoring hadrons in the radiation environment outside the accelerator are listed. Seventy-six references to the literature are included.

This report presents the preliminary findings from the first phase of the Environmental Survey of the US Department of Energy (DOE) Pittsburgh Energy Technology Center (PETC) conducted December 7--11, 1987. The Survey is being conducted by an interdisciplinary team of environmental specialists, led and managed by the Office of Environment, Safety and Health's Office of Environmental Audit. Individual team specialists are outside experts being supplied by a private contractor. The objective of the Survey is to identify environmental problems and areas of environmental risk associated with PETC. The Survey covers all environmental media and all areas of environmental regulation. It is being performed in accordance with the DOE Environmental Survey Manual. This phase of the Survey involves the review of existing site environmental data, observations of the operations carried on at PETC, and interviews with site personnel. The Survey team developed a Sampling and Analysis (S A) Plan to assist in further assessing certain environmental problems identified during its on-site Survey activities at PETC. The S A Plan will be executed by the Oak Ridge National Laboratory (ORNL). When completed, the Plan's results will be incorporated into the PETC Survey findings for inclusion into the Environmental Survey Summary Report. 64 refs., 23 figs., 29 tabs.

We report on a study of the galaxy environments of low redshift physical quasars pairs. We selected 20 pairs having projected separation Survey images, we evaluated the galaxy overdensity around these quasars in pairs and then compare it with that of a sample of isolated quasars with same redshift and luminosity. It is found that on average there is a systematic larger overdensity of galaxies around quasars in pairs with respect to that of isolated quasars. This may represent a significant link between nuclear activity and galaxy environment. However, at odds with that, the closest quasar pairs seem to inhabit poorer environments. Implications of present results and perspectives for future work are briefly discussed.

The shift towards economic activities that are environmentally sustain- able involves the need to overcome incumbent socio- technical regimes that are environmentally unsustainable but difficult to replace. Techno- logical and institutional co-evolution of practices and technologies with large...... scale effects and strong path dependencies create significant obsta- cles that stand in the way to adapting technologies that cause less or no damage to the environment.

Assessing associations between socio-economic environment and self-reported health in Amsterdam using bespoke environments.

Directory of Open Access Journals (Sweden)

Eleonore M Veldhuizen

Full Text Available The study of the relationship between residential environment and health at micro area level has a long time been hampered by a lack of micro-scale data. Nowadays data is registered at a much more detailed scale. In combination with Geographic Information System (GIS-techniques this creates opportunities to look at the relationship at different scales, including very local ones. The study illustrates the use of a 'bespoke environment' approach to assess the relationship between health and socio-economic environment.We created these environments by buffer-operations and used micro-scale data on 6-digit postcode level to describe these individually tailored areas around survey respondents in an accurate way. To capture the full extent of area effects we maximized variation in socio-economic characteristics between areas. The area effect was assessed using logistic regression analysis.Although the contribution of the socio-economic environment in the explanation of health was not strong it tended to be stronger at a very local level. A positive association was observed only when these factors were measured in buffers smaller than 200 meters. Stronger associations were observed when restricting the analysis to socioeconomically homogeneous buffers. Scale effects proved to be highly important but potential boundary effects seemed not to play an important role. Administrative areas and buffers of comparable sizes came up with comparable area effects.This study shows that socio-economic area effects reveal only on a very micro-scale. It underlines the importance of the availability of micro-scale data. Through scaling, bespoke environments add a new dimension to study environment and health.

Pollution in the Gulf: Monitoring the marine environment

International Nuclear Information System (INIS)

Fowler, S.W.

1993-01-01

More than 2 years after the Gulf conflict, scientists are continuing to keep a close watch on marine pollution stemming from the war. Following the conflict in early 1991, major concern was raised worldwide when an estimated four to eight million barrels of crude oil were directly released into the Persian Gulf from the Sea Island terminal in Kuwait. Such amounts clearly made it the largest oil spill in history. The catastrophe was exacerbated when Kuwaiti oil fields were ignited. The magnitude of the pollution, and the types of toxic contaminants involved, led to a worldwide response through the United Nations system. An inter-agency plan of action was developed quickly. As one of its steps, the co-ordinating agency - the United Nations Environment Programme (UNEP) - asked the IAEA's Marine Environment Laboratory (MEL) in Monaco to help make a preliminary assessment of the situation. The Laboratory's main goal in initial surveys was to map the extent and general degree of the war-related pollution throughout the Gulf. Since the initial surveys were done, IAEA-MEL scientists have been engaged in regional follow-up activities in ongoing attempts to obtain a clearer picture of the oil pollution's effects on the Gulf's marine environment. This article highlights the laboratory's work in the Gulf following the 1991 conflict, within the context of co-operative programmes and projects. 1 fig

Colleges have been experiencing reduced resource allocations, shifting student expectations, and organizational change. These changes increase employee stress at all levels. Ensuring that employee needs are being met and promoting a healthy and productive workforce has never been more important. To investigate employees' current perceptions of their work environments using the Work Environment Impact Scale-Self Rating (WEIS-SR). Full and part time employees on a small college campus in the United States were surveyed using the WEIS-SR through an online survey program to protect their anonymity. Perception of staffing levels, workplace support for a healthy lifestyle, number of supervisors, and personal health ratings contributed to employee perceptions of their work environment. There were also differences between staff, administration, and tenured and non-tenured faculty. From an occupational performance perspective, valuable information on employees' levels of volition, performance capacity and habituation, and perceptions of their physical and social environment in relation to their work environments was obtained. Further support for the use of the WEIS-SR and psychometric properties of the instrument (reliability and validity) was obtained.

1997-03-01

This report summarizes the results of 1-year survey on the radioactivities in foods and environments in Kanagawa Prefecture and the uranium level in the surroundings of Japan Nuclear Fuel Co., Ltd. (JNF), a nuclear fuel processing plant. The survey of radioactivity or radiation level was made in environments and foods including rain water, tap water, agricultural and livestock products, marine products, etc. For these subjects, analysis of nuclides and determination of spatial radiation dose rate were performed using γ-ray spectrometer. Only for rain water, the general β level was also determined. The uranium levels was monitored in river water and bottom materials, soil, Undaria pinnatifida, a seagrass in river mouths, etc. The present results show that there was no problem for all subjects tested in respect of radioactivity. And the uranium level around JNF was also within the normal range. The mean intake of 137 Cs was 0.085 Bq/Kg/day for the residents in the district of Hiratsuka Health Center and 0.077 Bq/Kg/day for those in the Yokohama city. Both levels were slightly higher than the previous ones. The survey results before and after the returns of nuclear powered ship were also within the normal range. (M.N.)

The Role Of Environment In Stellar Mass Growth

Science.gov (United States)

Thomas, Daniel

2017-06-01

In this talk I give a brief summary of methods to measure galaxy environment. I then discuss the dependence of stellar population properties on environmental density: it turns out that the latter are driven by galaxy mass, and galaxy environment only plays a secondary role, mostly at late times in low-mass galaxies. I show that this evidence has now been extended to stellar population gradients using the IFU survey SDSS/MaNGA that again turn out to be independent of environment, including central-satellite classification. Finally I present results from the DES, where the dependence of the stellar mass function with redshift and environmental density is explored. It is found that the fraction of massive galaxies is larger in high density environments than in low density environments. The low density and high density components converge with increasing redshift up to z 1.0 where the shapes of the mass function components are indistinguishable. This study shows how high density structures build up around massive galaxies through cosmic time, which sets new valuable constraints on galaxy formation models.

Web-Based Learning Environment Based on Students’ Needs

2017-08-01

Traditional learning needs to be improved since it does not involve active learning among students. Therefore, in the twenty-first century, the development of internet technology in the learning environment has become the main needs of each student. One of the learning environments to meet the needs of the teaching and learning process is a web-based learning environment. This study aims to identify the characteristics of a web-based learning environment that supports students’ learning needs. The study involved 542 students from fifteen faculties in a public higher education institution in Malaysia. A quantitative method was used to collect the data via a questionnaire survey by randomly. The findings indicate that the characteristics of a web-based learning environment that support students’ needs in the process of learning are online discussion forum, lecture notes, assignments, portfolio, and chat. In conclusion, the students overwhelmingly agreed that online discussion forum is the highest requirement because the tool can provide a space for students and teachers to share knowledge and experiences related to teaching and learning.

Wage, Work Environment, and Staffing: Effects on Nurse Outcomes

Science.gov (United States)

McHugh, Matthew D.; Ma, Chenjuan

2015-01-01

Research has shown that hospitals with better nurse staffing and work environments have better nurse outcomes—less burnout, job dissatisfaction, and intention to leave the job. Many studies, however, have not accounted for wage effects, which may confound findings. By using a secondary analysis with cross-sectional administrative data and a four-state survey of nurses, we investigated how wage, work environment, and staffing were associated with nurse outcomes. Logistic regression models, with and without wage, were used to estimate the effects of work environment and staffing on burnout, job dissatisfaction, and intent to leave. We discovered that wage was associated with job dissatisfaction and intent to leave but had little influence on burnout, while work environment and average patient-to-nurse ratio still have considerable effects on nurse outcomes. Wage is important for good nurse outcomes, but it does not diminish the significant influence of work environment and staffing on nurse outcomes. PMID:25121923

As the engineers find it very important to teach working environment at engineering schools it must be considered what kind of curriculum would be most effective for the engineering career. Finally, the engineers do not perceive that management or others......This study confirms that many engineers are not aware that they influence the working environment of other people through their engineering. Also, it indicates that the extent of influence dependends on engineering domain and task content. Many engineers and enterprises have an espoused theory...... expressing a positive attitude towards working environment considerations in engineering. However, the theory-in-action seems to be quite different. Engineers do not know what to do in relation to working environment considerations.

The present survey and study relate to the medium to long term policies for technological development of energy and environment related technologies, and are intended to develop a system that can evaluate the importance, feasibility, expected realization time, and expected cost of the technologies, including their synergetic effects. The survey and study are intended to provide clear guidelines for planning the technological development policies on which of the technological development should be promoted in what ways, based on the evaluation given by the use of the system. The report describes in Section 1 to adopt two types of approaches of a 'technology map' and a 'network chart evaluation system' to achieve the goal. Section 2, after describing the results of surveys on the past study cases of technology evaluation, describes that the present approach has new features that are different from conventional ones. Section 3 states the results of surveys on the basic technologies to prevent global warming, and shows cases of preparing maps that notice on energy flows. Section 4 relates to network chart evaluating methods. Section 5 describes the results of surveys that have been made in relation with chronological progress of the technological development, in preparation for surveys to be made in the coming fiscal years.

In this work we present the first comprehensive survey of Brain Interface (BI) technology designs published prior to January 2006. Detailed results from this survey, which was based on the Brain Interface Design Framework proposed by Mason and Birch, are presented and discussed to address the following research questions: (1) which BI technologies are directly comparable, (2) what technology designs exist, (3) which application areas (users, activities and environments) have been targeted in these designs, (4) which design approaches have received little or no research and are possible opportunities for new technology, and (5) how well are designs reported. The results of this work demonstrate that meta-analysis of high-level BI design attributes is possible and informative. The survey also produced a valuable, historical cross-reference where BI technology designers can identify what types of technology have been proposed and by whom.

Organizational effects on job satisfaction, burnout, work-life balance, and perceived support have not been studied in the context of the clinical learning environment. We evaluated the relationship between academic resources and resident well-being, the clinical learning environment, and in-service examination performance of surgical residents. Residents of general surgery and surgical specialty programs were recruited from March 2016 through June 2016 across the Southeast, Mid-Atlantic, and Northeast regions. Program directors were asked to allow distribution of a paper survey or to forward an electronic survey link onto residents. Five dichotomous questions were asked regarding access to academic resources. Validated measures were obtained assessing resident well-being and perceived clinical learning environment. Data were analyzed through t-tests and chi-squared test of independence. We received 276 respondents across 50 programs. Residents perceiving adequate support to succeed had less burnout (P = 0.008), better resilience (P = 0.009), better job satisfaction (P workplace climate (P < 0.001), better organizational support (P < 0.001), and were more likely to have high performance on the in-service examination (P = 0.001). Specific resources including educational stipends, review questions, in-service board prep, and support for poor performers correlated with improved well-being and perceived clinical learning environment. Provision of academic resources has implications beyond in-service examination performance, correlating with improved resident well-being and perceptions of the clinical learning environment.

Although the introduction of computerized working environment to the nuclear facilities, the study on the human factors impacts of computers and automation has not been enough like the other industries. It is necessary to prepare the way to cope with the negative aspects in spite of many positive aspects of computerization in nuclear. This study is an empirical study including the survey of the human factor concerning, especially to the cognitive response of operators' and the experiments on the error proneness. At first, we survey the design and its changes of operator interface and interaction in nuclear power plants, and conclude five human factor issues. We discuss situation awareness issues as one of the major human factor concerning, and the assessment method. Secondly, a questionnaire and interviews survey to the operator's response characteristics are performed for possible criterion measures tot he in-depth study on the cognitive characteristics. Finally, several experiments are conducted to test the error proneness. The issues and findings of this study could be utilized to any further study on the cognitive characteristic of operators to the computerized work environment

The Next Generation Virgo Cluster Survey (NGVS) is a program that uses the 1 deg 2 MegaCam instrument on the Canada-France-Hawaii Telescope to carry out a comprehensive optical imaging survey of the Virgo cluster, from its core to its virial radius—covering a total area of 104 deg 2 —in the u*griz bandpasses. Thanks to a dedicated data acquisition strategy and processing pipeline, the NGVS reaches a point-source depth of g ≈ 25.9 mag (10σ) and a surface brightness limit of μ g ∼ 29 mag arcsec –2 (2σ above the mean sky level), thus superseding all previous optical studies of this benchmark galaxy cluster. In this paper, we give an overview of the technical aspects of the survey, such as areal coverage, field placement, choice of filters, limiting magnitudes, observing strategies, data processing and calibration pipelines, survey timeline, and data products. We also describe the primary scientific topics of the NGVS, which include: the galaxy luminosity and mass functions; the color-magnitude relation; galaxy scaling relations; compact stellar systems; galactic nuclei; the extragalactic distance scale; the large-scale environment of the cluster and its relationship to the Local Supercluster; diffuse light and the intracluster medium; galaxy interactions and evolutionary processes; and extragalactic star clusters. In addition, we describe a number of ancillary programs dealing with 'foreground' and 'background' science topics, including the study of high-inclination trans-Neptunian objects; the structure of the Galactic halo in the direction of the Virgo Overdensity and Sagittarius Stream; the measurement of cosmic shear, galaxy-galaxy, and cluster lensing; and the identification of distant galaxy clusters, and strong-lensing events.

Full Text Available The functionalist paradigm of organisational culture (OC views culture as a variable subject to conscious manipulation and control in order to solve organisational challenges. Therefore, this paper provides information on how OC is a solution to the challenges in Quantity Surveying firms (QSFs.  This was achieved by eliciting the dimensions of OC in forty two QSFs in Lagos, Nigeria, which are the business, people and external environment dimensions. The paper concludes that OC is a relevant solution to the identity and management related challenges in QSFs. Specifically, the paper informs on the implications of business and people dimensions of OC as a solution to the identity challenges, as well as on the implication of the external environment dimension of OC to the management challenges. Based on the findings, practical implications and recommendations were directed at the management and employees QSs in QSFs and Quantity Surveying researchers.

The basic parameters of the sedimentation environment are considered: the Western Boundary Deep Current that transports sedimentary material and distributes it on the survey area; the nepheloid layer, its features, and the distribution of the concentrations and particulate standing crop in it; the distribution of the horizontal and vertical fluxes of the sedimentary material; and the bottom sediments and their absolute masses. The comparison of the vertical fluxes of the particulate matter and the absolute masses of the sediments showed that the contemporary fluxes of sedimentary material to the bottom provided the distribution of the absolute masses of the sediments in the survey area during the Holocene.

Targeting occupational health and safety interventions to different groups of employees and sectors is important. The aim of this study was to explore the environment-intervention fit of a Danish psychosocial work environment intervention program for the residential and home care sector. Focus group interviews with employees and interviews with mangers were conducted at 12 selected workplaces and a questionnaire survey was conducted with managers at all 115 workplaces. The interventions enhanced the probability of employees experiencing more “good” work days, where they could make a difference to the lives of clients. The interventions may therefore be characterized as culturally compelling and having a good fit with the immediate work environment of employees. The interventions furthermore seemed to fit well with the wider organizational environment and with recent changes in the societal and economic context of workplaces. However, some workplaces had difficulties with involving all employees and adapting the interventions to the organization of work. The findings suggest that flexibility and a variety of strategies to involve all employees are important aspects, if interventions are to fit well with the care sector. The focus on employees' conceptualization of a “good” work day may be useful for intervention research in other sectors. PMID:26380356

Han, Xueying; Appelbaum, Richard P

2018-01-01

In keeping with China's President Xi Jinping's "Chinese Dream," China has set a goal of becoming a world-class innovator by 2050. China's higher education Science, Technology, Engineering, and Math (STEM) research environment will play a pivotal role in influencing whether China is successful in transitioning from a manufacturing-based economy to an innovation-driven, knowledge-based economy. Past studies on China's research environment have been primarily qualitative in nature or based on anecdotal evidence. In this study, we surveyed STEM faculty from China's top 25 universities to get a clearer understanding of how faculty members view China's overall research environment. We received 731 completed survey responses, 17% of which were from individuals who received terminal degrees from abroad and 83% of which were from individuals who received terminal degrees from domestic institutions of higher education. We present results on why returnees decided to study abroad, returnees' decisions to return to China, and differences in perceptions between returnees and domestic degree holders on the advantages of having a foreign degree. The top five challenges to China's research environment identified by survey respondents were: a promotion of short-term thinking and instant success (37% of all respondents); research funding (33%); too much bureaucratic or governmental intervention (31%); the evaluation system (27%); and a reliance on human relations (26%). Results indicated that while China has clearly made strides in its higher education system, there are numerous challenges that must be overcome before China can hope to effectively produce the kinds of innovative thinkers that are required if it is to achieve its ambitious goals. We also raise questions about the current direction of education and inquiry in China, particularly indications that government policy is turning inward, away from openness that is central to innovative thinking.

Techniques employed for detection of hot particles in the marine environment

International Nuclear Information System (INIS)

2007-01-01

During the decommissioning of the Maine Yankee nuclear plant, several methods were developed and employed to survey for hot particles in the marine environment surrounding the site. The methods used and the sensitivities achieved in the search for environmentally dispersed particles during the various decommissioning activities performed are described in detail. Surveys were performed on dry soil, exposed marine sediment and submerged marine sediment. Survey techniques ranged from the use of the basic NaI detector coupled to a count rate meter to an intrinsic germanium detector deployed in a submarine housing coupled to a multi-channel analyser. The initial surveys consisted of collecting samples of marine sediment, spreading them out over a 1 m 2 surface in a thin layer, and scanning the deposited sediment by hand using a 5 cm by 5 cm NaI detector coupled to a standard count rate meter. This technique was later replaced by walkover scans with the 5 cm by 5 cm NaI detector moved in a serpentine pattern over the sediment surface. By coupling the detector to a 'smart meter', an alarm set point could be used to alert the surveyor to the presence of a particle within the instrument's field of view. A similar technique, with the detector mounted in a watertight housing secured to the end of a pole, was also employed to scan underwater locations. The most sensitive method developed for performing underwater surveys was the use of the intrinsic germanium detector placed in a submarine housing. Detailed descriptions of the methods employed and the results obtained are presented. This work demonstrates that there are several approaches to surveying for discrete particles in the marine environment and the relative merits of each are considered

The purpose of the Shallow Survey common dataset is a comparison of the different technologies utilized for data acquisition in the shallow survey marine environment. The common dataset consists of a series of surveys conducted over a common area of seabed using a variety of systems. It provides equipment manufacturers the opportunity to showcase their latest systems while giving hydrographic researchers and scientists a chance to test their latest algorithms on the dataset so that rigorous comparisons can be made. Five companies collected data for the Common Dataset in the Wellington Harbor area in New Zealand between May 2010 and May 2011; including Kongsberg, Reson, R2Sonic, GeoAcoustics, and Applied Acoustics. The Wellington harbor and surrounding coastal area was selected since it has a number of well-defined features, including the HMNZS South Seas and HMNZS Wellington wrecks, an armored seawall constructed of Tetrapods and Akmons, aquifers, wharves and marinas. The seabed inside the harbor basin is largely fine-grained sediment, with gravel and reefs around the coast. The area outside the harbor on the southern coast is an active environment, with moving sand and exposed reefs. A marine reserve is also in this area. For consistency between datasets, the coastal research vessel R/V Ikatere and crew were used for all surveys conducted for the common dataset. Using Triton's Perspective processing software multibeam datasets collected for the Shallow Survey were processed for detail analysis. Datasets from each sonar manufacturer were processed using the CUBE algorithm developed by the Center for Coastal and Ocean Mapping/Joint Hydrographic Center (CCOM/JHC). Each dataset was gridded at 0.5 and 1.0 meter resolutions for cross comparison and compliance with International Hydrographic Organization (IHO) requirements. Detailed comparisons were made of equipment specifications (transmit frequency, number of beams, beam width), data density, total uncertainty, and

A positive learning environment and quality of course content have an imperative role in academic achievement of students. This study aims to assess students' point of view about the quality of education and social environment of a public sector medical college in Pakistan. Relative scarcity of data from students' perspective merited this study. A cross-sectional survey was undertaken at Ayub Medical College, Abbottabad, Pakistan, including 300 medical students from all five years of the MBBS course. Systematic random sampling was used with a kth interval of 4 for each class. Self-administered questionnaire was used and contained items related to academics, learning environment, learning resources, teaching methodologies and student-friendly activities. The data were analysed using SPSS-16. There were 265 respondents (88.3%) to the questionnaire with males accounting for 58.9% (n=156). In general students showed satisfaction with quality of content being taught; however there was discontent towards various academic and non- academic facilities provided to the students. Only 44.10% and 31.50% students reported provision of academic related facilities and interactive sessions as up to mark respectively; 83% students reported that undergraduate medical research was in need of improvement; 55.5% and 60.2% reported that facilities in hostel and recreational facilities needed improvement respectively; and 52.8% students stated presence of a healthy, student friendly, encouraging environment was not up to mark. Although course content and teaching methodologies are generally satisfactory, a healthy, student friendly, encouraging environment is vet to be created to help students foster their abilities completely.

An aerial radiological survey was conducted during the period of September 10 to 18, 1990, over a 40-square-mile (104-square-kilometer) area surrounding the Millstone Nuclear Power Station (MNPS). The MNPS is located on the Long Island Sound shoreline, three kilometers south of Waterford, Connecticut. The purpose of the survey was to measure and document the terrestrial gamma ray environment of the plant and surrounding areas. A contour map showing radiation exposure rates at 1 meter above ground level was constructed from the aerial data and overlaid on an aerial photograph and a United States Geological Survey map of the area. The exposure rates within the survey region are quite uniform. The area is characterized by an exposure rate of 10-12 microroentgens per hour including an estimated cosmic ray contribution of 3.6 μR/h. This is typical of natural background. The only exception to the natural background readings is the Millstone station itself, which is characterized by an exposure rate consistent with the standard operation of the reactor units. Radionuclide assays of soil samples and pressurized-ion-chamber gamma ray measurements were obtained at five locations within the survey boundaries. These measurements were taken in support of, and are in agreement with, the aerial data. The radiological environment near the plant is consistent with normal plant operation

In this paper data are reported on the natural radiation environments in Italian mines and spas. The survey and relevant internal exposure assessment indicated that large groups of persons are chronically exposed to nonnegligible levels of radon and daughter products, which are always present in variable concentrations. Since the radiological environment of the spa is similar to that of mine one, there is the possibility of comparing two population groups living in different conditions, but similarly exposed, to evaluate the synergistic factors, if any

Cloud computing has pervaded through every aspect of Information technology in past decade. It has become easier to process plethora of data, generated by various devices in real time, with the advent of cloud networks. The privacy of users data is maintained by data centers around the world and hence it has become feasible to operate on that data from lightweight portable devices. But with ease of processing comes the security aspect of the data. One such security aspect is secure file transfer either internally within cloud or externally from one cloud network to another. File management is central to cloud computing and it is paramount to address the security concerns which arise out of it. This survey paper aims to elucidate the various protocols which can be used for secure file transfer and analyze the ramifications of using each protocol.

Ecological validity of virtual environments to assess human navigation ability

Directory of Open Access Journals (Sweden)

2015-05-01

Full Text Available Route memory is frequently assessed in virtual environments. These environments can be presented in a fully controlled manner and are easy to use. Yet they lack the physical involvement that participants have when navigating real environments. For some aspects of route memory this may result in reduced performance in virtual environments. We assessed route memory performance in four different environments: real, virtual, virtual with directional information (compass, and hybrid. In the hybrid environment, participants walked the route outside on an open field, while all route information (i.e. path, landmarks was shown simultaneously on a handheld tablet computer. Results indicate that performance in the real life environment was better than in the virtual conditions for tasks relying on survey knowledge, like pointing to start and end point, and map drawing. Performance in the hybrid condition however, hardly differed from real life performance. Performance in the virtual environment did not benefit from directional information. Given these findings, the hybrid condition may offer the best of both worlds: the performance level is comparable to that of real life for route memory, yet it offers full control of visual input during route learning.

1989-01-01

The results of a total gamma radiometric survey of Jamaica, carried out with car-borne instrumentation, are presented and the data compared with the contents of potassium, thorium and uranium in rocks and in surface (soil, stream-sediment, pan concentrate and water) samples obtained at six sites selected to be representative of the principal rock types and surface environments of Jamaica. The work formed part of an orientation study for a regional geochemical survey of the CARICOM countries of the Caribbean. The initial results indicate that enhanced gamma activity is correlated with enrichment in uranium and thorium, but not potassium, in terra rossa soils and/or bauxite deposits in limestone. Elsewhere, gamma levels are increased on the Above Rocks Cretaceous basement Inlier, where they correlate generally with the presence of volcanogenic sediments and a granodiorite intrusion. The lowest radioactivity was recorded in the vicinity of ultrabasic rocks in the Blue Mountains Inlier. (author)

An aerial radiological survey of the Perry Nuclear Power Plant and surrounding area, North Perry, Ohio: Date of survey: April 1987

1987-01-01

An aerial radiological survey was conducted over the Perry Nuclear Power Plant, North Perry, Ohio. The purpose of the 234-square-kilometer (91-square-mile) survey was to document the terrestrial gamma environment of the plant and surrounding area. An exposure rate contour map at 1 meter above ground level was constructed from the gamma data and overlaid on an aerial photograph and map of the area. Exposure rates increased from 0 microroentgens per hour (μR/h) over Lake Erie to 9 μR/h as the distance from Lake Erie increased. Only one anomalous area appears on the map, which is due to an excess of Bi-214 in a landfill area. Ground-based exposure rate measurements and soil samples were obtained to support the aerial data. Oblique aerial photographs of the plant were also acquired during the survey. 6 refs., 6 figs., 1 tab

We investigate the effect of internal control employees (ICEs) on internal control quality. Using special survey data from Chinese listed firms, we find that ICE quality has a significant positive influence on internal control quality. We examine the effect of monitoring on this result and find that the effect is more pronounced for firms with strict monitoring environments, especially when the firms implement the Chinese internal control regulation system (CSOX), have higher institutional ow...

Physical therapists' perception of workplace ethics in an evolving health-care delivery environment: a cross-sectional survey.

Physical therapists are trained and obligated to deliver optimal health care and put patients first above all else. In the changing health-care environment, health-care organizations are grappling with controlling cost and increasing revenues. Moral distress may be created when physical therapists' desire to provide optimal care conflicts with their organization's goals to remain financially viable or profitable. Moral distress has been associated with low perception of ethical environment, professional burnout, and high turnover in organizations. This study identified groups who may be vulnerable to low perception of organizational ethical environment and identified self-reported strategies to remedy these perceptions. An ethics environment questionnaire was mailed to a random sample of 1200 physical therapists in Georgia. Respondents (n = 340) were analyzed by age, workplace setting, and position in organization. Therapists working in skilled nursing/assisted living environments scored the lowest on the questionnaire and voiced concerns regarding their ethical work environments. Owners and executives perceived their organizations to be more ethical than front-line clinicians. Respondent concerns included high productivity standards, aggressive coding/billing policies, decreased reimbursement, and increased insurance regulation. Possible solutions included more frequent communication between management and clinicians about ethics, greater professional autonomy, and increased training in business ethics and finance.
