We present the first systematic 1.4 GHz Very Large Array radio continuum survey of fossil galaxy group candidates. These are virialized systems believed to have assembled over a gigayear in the past through the merging of galaxy group members into a single, isolated, massive elliptical galaxy and featuring an extended hot X-ray halo. We use new photometric and spectroscopic data from Sloan Digital Sky Survey Data Release 7 to determine that three of the candidates are clearly not fossil groups. Of the remaining 30 candidates, 67% contain a radio-loud (L 1.4GHz > 10 23 W Hz –1 ) active galactic nucleus (AGN) at the center of their dominant elliptical galaxy. We find a weak correlation between the radio luminosity of the AGN and the X-ray luminosity of the halo suggesting that the AGN contributes to energy deposition into the intragroup medium. We only find a correlation between the radio and optical luminosity of the central elliptical galaxy when we include X-ray-selected, elliptically dominated non-fossil groups, indicating a weak relationship between AGN strength and the mass assembly history of the groups. The dominant elliptical galaxy of fossil groups is on average roughly an order of magnitude more luminous than normal group elliptical galaxies in optical, X-ray, and radio luminosities and our findings are consistent with previous results that the radio-loud fraction in elliptical galaxies is linked to the stellar mass of a population. The current level of activity in fossil groups suggests that AGN fueling continues long after the last major merger. We discuss several possibilities for fueling the AGN at the present epoch.

Detection of blood group is an essential factor in critical conditions before performing blood transfer. At presently tests are conducted by lab technicians manually in the laboratory. When the test is done by technicians with large samples it becomes monotonous to do and sometimes it leads to incorrect results and even its time consuming to get the result. The research survey proposal is to reduce the physical work to identify the blood group with a paper-based device. The paper is having a long thermometer with two ends. By using this we can detect the blood type by changing the color of the paper. Chemical reactions between dye, Bromo creosol green, and blood serum proteins, were performed to test the blood sample. The paper becomes teal or brown color, depending on whether the association of antibodies and antigens are present. It gives the result within 30 seconds, which is quicker than traditional detection system. The tested blood sample had a good accuracy rate.

Does an offer for a free on-line continuing medical education (CME) activity increase physician survey response rate? A randomized trial.

Achieving a high response rate in a physician survey is challenging. Monetary incentives increase response rates but obviously add cost to a survey project. We wondered whether an offer of a free continuing medical education (CME) activity would be effective in improving survey response rate. As part of a survey of a national sample of physicians, we randomized half to an offer for a free on-line CME activity upon completion of a web-based survey and the other half to no such offer. We compared response rates between the groups. A total of 1214 out of 8477 potentially eligible physicians responded to our survey, for an overall response rate of 14.3%. The response rate among the control group (no offer of CME credit) was 16.6%, while among those offered the CME opportunity, the response rate was 12.0% (p offer for a free on-line CME activity did not improve physician survey response rate. On the contrary, the offer for a free CME activity actually appeared to worsen the response rate. © 2011 Viera et al; licensee BioMed Central Ltd.

Full Text Available Estimation of population exposure is a main component of human health risk assessment for environmental contaminants. Population-level exposure assessments require time-activity pattern distributions in relation to microenvironments where people spend their time. Societal trends may have influenced time-activity patterns since previous Canadian data were collected 15 years ago. The Canadian Human Activity Pattern Survey 2 (CHAPS 2 was a national survey conducted in 2010–2011 to collect time-activity information from Canadians of all ages. Five urban and two rural locations were sampled using telephone surveys. Infants and children, key groups in risk assessment activities, were over-sampled. Survey participants (n = 5,011 provided time-activity information in 24-hour recall diaries and responded to supplemental questionnaires concerning potential exposures to specific pollutants, dwelling characteristics, and socio-economic factors. Results indicated that a majority of the time was spent indoors (88.9%, most of which was indoors at home, with limited time spent outdoors (5.8% or in a vehicle (5.3%. Season, age, gender and rurality were significant predictors of time activity patterns. Compared to earlier data, adults reported spending more time indoors at home and adolescents reported spending less time outdoors, which could be indicative of broader societal trends. These findings have potentially important implications for assessment of exposure and risk. The CHAPS 2 data also provide much larger sample sizes to allow for improved precision and are more representative of infants, children and rural residents.

The study characterized three groups with different levels of familiarity with personal health information management (PHIM) in terms of their demographics, health knowledge, technological competency, and information sources and barriers. In addition, the authors examined differences among PHIM groups in subjective self-ratings and objective test scores for health literacy. A total of 202 survey participants were recruited using Amazon's Mechanical Turk (mTurk) service, a crowdsourcing Internet service. Using K-means clustering, three groups with differing levels of familiarity with PHIM were formed: Advanced, Intermediate, and Basic. The Advanced group was the youngest, and the Basic group contained the highest proportion of males, whereas the Intermediate group was the oldest and contained the fewest males. The Advanced group was significantly more likely to engage in provider- or hospital-initiated PHIM activities such as emailing with providers, viewing test results online, and receiving summaries of hospital visits via email or websites than the other groups. The Basic group had significantly lower information management skills and Internet use than the other groups. Advanced and Basic groups reported significant differences in several information barriers. While the Advanced group self-reported the highest general literacy, they scored lowest on an objective health literacy test. For effective personal health records management, it is critical to understand individual differences in PHIM using a comprehensive measure designed to assess personal health records-specific activities. Because they are trained to perform an array of information management activities, medical librarians or patient educators are well positioned to promote the effective use of personal health records by health consumers.

Paramedics participate in continuing medical education (CME) to maintain their skills and knowledge. An understanding of learning styles is important for education to be effective. This study examined the preferred learning styles of ground ambulance paramedics and describes how their preferred learning styles relate to the elective CME activities these paramedics attend. All paramedics (n=1,036) employed in a provincial ground ambulance service were invited to participate in a survey containing three parts: demographics, learning style assessed by the Kolb Learning Style Inventory (LSI), and elective CME activity. 260 paramedics (25%) participated in the survey. Preferred learning styles were: assimilator, 28%; diverger, 25%; converger, 24%; and accommodator, 23%. Advanced life support (ALS) providers had a higher proportion of assimilators (36%), and basic life support (BLS) providers had a higher proportion of divergers (30%). The learning style categories of CME activities attended by paramedics were: assimilators, 25%; divergers, 26%; convergers, 25%; and accommodators, 24%. These results suggest that paramedics are a diverse group of learners, and learning style differs within their demographics. Paramedics attend CME activities that complement all learning styles. Organizations providing education opportunities to paramedics should consider paramedics a diverse learning group when designing their CME programs.

Hadfield Ruth M

2010-08-01

Full Text Available Abstract Background Research into the effects of common activities during pregnancy is sparse and often contradictory. To examine whether common activities are an acute trigger of pregnancy complications the prevalence of these activities are necessary to determine sample size estimates. The aim of this study is to ascertain the prevalence of selected activities in any seven day period during pregnancy. Methods The study was conducted in the antenatal clinic of a teaching hospital with tertiary obstetric and neonatal care in Sydney, Australia between August 2008 and April 2009. Women who were at least 20 weeks pregnant and able to read English completed a questionnaire to assess whether they had performed a list of activities in the seven days prior to survey completion. Results were analysed using frequency tabulations, contingency table analyses and chi square tests. Results A total of 766 surveys were completed, 29 surveys were excluded as the women completing them were less than 20 weeks pregnant, while 161 women completed the survey more than once. Ninety seven per cent of women completed the survey when approached for the first time, while 87% completed the survey when approached a subsequent time. In the week prior to completing the survey 82.6% of women had consumed a caffeinated beverage, 42.1% had had sexual intercourse, 32.7% had lifted something over 12 kilograms, 21.4% had consumed alcohol and 6.4% had performed vigorous exercise. The weekly prevalence of heavy lifting was higher for multiparous women compared to nulliparous women. Conclusions The results of this study can be used to inform future research into activities as acute triggers of pregnancy complications.

Active and passive spatial learning in human navigation: acquisition of survey knowledge.

Chrastil, Elizabeth R; Warren, William H

It seems intuitively obvious that active exploration of a new environment would lead to better spatial learning than would passive visual exposure. It is unclear, however, which components of active learning contribute to spatial knowledge, and previous literature is decidedly mixed. This experiment tests the contributions of 4 components to metric survey knowledge: visual, vestibular, and podokinetic information and cognitive decision making. In the learning phase, 6 groups of participants learned the locations of 8 objects in a virtual hedge maze by (a) walking, (b) being pushed in a wheelchair, or (c) watching a video, crossed with (1) making decisions about their path or (2) being guided through the maze. In the test phase, survey knowledge was assessed by having participants walk a novel shortcut from a starting object to the remembered location of a test object, with the maze removed. Performance was slightly better than chance in the passive video condition. The addition of vestibular information did not improve performance in the wheelchair condition, but the addition of podokinetic information significantly improved angular accuracy in the walking condition. In contrast, there was no effect of decision making in any condition. The results indicate that visual and podokinetic information significantly contribute to survey knowledge, whereas vestibular information and decision making do not. We conclude that podokinetic information is the primary component of active learning for the acquisition of metric survey knowledge. PsycINFO Database Record (c) 2013 APA, all rights reserved.

While astrobiology is apparently growing steadily around the world, in terms of the number of researchers drawn into this interdisciplinary area and teaching courses provided for new students, there have been very few studies conducted to chart this expansion quantitatively. To address this deficiency, the Astrobiology Society of Britain (ASB) conducted a questionnaire survey of universities and research institutions nationwide to ascertain the current extent of astrobiology research and teaching in the UK. The aim was to provide compiled statistics and an information resource for those who seek research groups or courses of study, and to facilitate new interdisciplinary collaborations. The report here summarizes details gathered on 33 UK research groups, which involved 286 researchers (from undergraduate project students to faculty members). The survey indicates that around 880 students are taking university-level courses, with significant elements of astrobiology included, every year in the UK. Data are also presented on the composition of astrobiology students by their original academic field, which show a significant dominance of physics and astronomy students. This survey represents the first published systematic national assessment of astrobiological academic activity and indicates that this emerging field has already achieved a strong degree of penetration into the UK academic community.

The aim of the study was to estimate the physical activity (PA) level among the professional college students in North India. One hundred three professional college students in the age group of 18-25 years were recruited by simple random sampling for this cross-sectional online survey. The survey was advertised on the social networking sites (Facebook, WhatsApp) through a link www.surveymonkey.com/r/MG-588BY. A Short Form of International Physical Activity Questionnaire was used for this survey study. The questionnaire included total 8 questions on the basis of previous 7 days. The questionnaire consists of 3 main categories which were vigorous, moderate and high PA. Time spent in each activity level was multiplied with the metabolic equivalent of task (MET), which has previously set to 8.0 for vigorous activity, 4.0 for moderate activity, 3.3 for walking, and 1.5 for sitting. By multiplying MET with number of days and minutes performed weekly, amount of each activity level was calculated and measured as MET-min/wk. Further by adding MET minutes for each activity level, total MET-min/wk was calculated. Total number of 100 students participated in this study, and it was shown that all professional course students show different levels in PA. The total PA level among professional college students, which includes, physiotherapy, dental, medical, nursing, lab technician, pharmacy, management, law, engineering, were 434.4 (0-7,866), 170.3 (0-1,129), 87.7 (0-445), 102.8 (0-180), 469 (0-1,164), 0 (0-0), 645 (0-1,836), 337 (0-1,890), 396 (0-968) MET-min/wk respectively. PA levels among professional college students in North India have been established.

Patient grouping for dose surveys and establishment of diagnostic reference levels in paediatric computed tomography

Vassileva, J.; Rehani, M.

2015-01-01

There has been confusion in literature on whether paediatric patients should be grouped according to age, weight or other parameters when dealing with dose surveys. The present work aims to suggest a pragmatic approach to achieve reasonable accuracy for performing patient dose surveys in countries with limited resources. The analysis is based on a subset of data collected within the IAEA survey of paediatric computed tomography (CT) doses, involving 82 CT facilities from 32 countries in Asia, Europe, Africa and Latin America. Data for 6115 patients were collected, in 34.5 % of which data for weight were available. The present study suggests that using four age groups, <1, >1-5, >5-10 and >10-15 y, is realistic and pragmatic for dose surveys in less resource countries and for the establishment of DRLs. To ensure relevant accuracy of results, data for >30 patients in a particular age group should be collected if patient weight is not known. If a smaller sample is used, patient weight should be recorded and the median weight in the sample should be within 5-10 % from the median weight of the sample for which the DRLs were established. Comparison of results from different surveys should always be performed with caution, taking into consideration the way of grouping of paediatric patients. Dose results can be corrected for differences in patient weight/age group. (authors)

Full text: This work has been performed as part of the EC project SAVEC (Spatial Analysis of Vulnerable Areas in Central Europe), expanding the EC project SAVE (Spatial Analysis of Vulnerable Ecosystems in Europe). Spatial analysis of dietary habits can be used as a tool for predicting areas where people are more vulnerable to radioactive fallout. Common dietary data such as national statistics and household budget surveys can be used for this purpose. The resolution of such data is not good enough, though, for identifying smaller critical groups with respect to dietary habits. Wild berries and mushrooms, wild fowl, game meat and freshwater fish usually have higher 137 Cs activity concentration levels than agricultural products. In the long term, these foodstuffs can contribute substantially to the internal dose even if consumed in small amounts. Yet, they are usually not included in household budget surveys or national consumption statistics. A specific dietary survey in the form of a questionnaire is the best way to get accurate information on individual diets. The questionnaires can be designed to cover radiologically important foodstuffs, such as those from the forest ecosystem. Within the SAVEC project a questionnaire detailing the consumption of foods from the forest ecosystem has been distributed to hunters in Poland, Hungary and the Czech Republic. The results from this investigation and the identification of critical groups with respect to dietary habits in the three Central European countries will be presented. (author)

In order to upgrade activity and likelihood ratio on active potential evaluation of the water active fault with possibility of severe effect on nuclear facilities, by generally applying the conventional procedures to some areas and carrying out a demonstration survey, a qualitative upgrading on survey to be conducted by the executives was planned. In 1998 fiscal year, among the water active faults classified to the trench and the inland types, three dimensional survey on the inland type water active fault. The survey was carried out at the most southern part of aftershock area in the 1983 Nihonkai-Chubu earthquake, which is understood to be a place changing shallow geological structure (propagation of fault) from an old report using the sonic survey. As a result, a geological structure thought to be an active fault at a foot of two ridge topographies was found. Each fault was thought to be a reverse fault tilt to its opposite direction and an active fault cutting to its sea bottom. (G.K.)

Peer support is an established component of recovery from bipolar disorder, and online support groups may offer opportunities to expand the use of peer support at the patient's convenience. Prior research in bipolar disorder has reported value from online support groups. To understand the use of online support groups by patients with bipolar disorder as part of a larger project about information seeking. The results are based on a one-time, paper-based anonymous survey about information seeking by patients with bipolar disorder, which was translated into 12 languages. The survey was completed between March 2014 and January 2016 and included questions on the use of online support groups. All patients were diagnosed by a psychiatrist. Analysis included descriptive statistics and general estimating equations to account for correlated data. The survey was completed by 1222 patients in 17 countries. The patients used the Internet at a percentage similar to the general public. Of the Internet users who looked online for information about bipolar disorder, only 21.0% read or participated in support groups, chats, or forums for bipolar disorder (12.8% of the total sample). Given the benefits reported in prior research, clarification of the role of online support groups in bipolar disorder is needed. With only a minority of patients using online support groups, there are analytical challenges for future studies.

Evaluating human activity recognition systems usually implies following expensive and time-consuming methodologies, where experiments with humans are run with the consequent ethical and legal issues. We propose a novel evaluation methodology to overcome the enumerated problems, which is based on surveys for users and a synthetic dataset generator tool. Surveys allow capturing how different users perform activities of daily living, while the synthetic dataset generator is used to create properly labelled activity datasets modelled with the information extracted from surveys. Important aspects, such as sensor noise, varying time lapses and user erratic behaviour, can also be simulated using the tool. The proposed methodology is shown to have very important advantages that allow researchers to carry out their work more efficiently. To evaluate the approach, a synthetic dataset generated following the proposed methodology is compared to a real dataset computing the similarity between sensor occurrence frequencies. It is concluded that the similarity between both datasets is more than significant.

We propose a novel evaluation methodology to overcome the enumerated problems, which is based on surveys for users and a synthetic dataset generator tool. Surveys allow capturing how different users perform activities of daily living, while the synthetic dataset generator is used to create properly labelled activity datasets modelled with the information extracted from surveys. Important aspects, such as sensor noise, varying time lapses and user erratic behaviour, can also be simulated using the tool. The proposed methodology is shown to have very important advantages that allow researchers to carry out their work more efficiently. To evaluate the approach, a synthetic dataset generated following the proposed methodology is compared to a real dataset computing the similarity between sensor occurrence frequencies. It is concluded that the similarity between both datasets is more than significant. PMID:25856329

The purpose of this study was to survey experts in the field of hip arthroscopy from the Multicenter Arthroscopy of the Hip Outcomes Research Network (MAHORN) group to determine the frequency of symptomatic intra-abdominal fluid extravasation (IAFE) after arthroscopic hip procedures, identify potential risk factors, and develop preventative measures and treatment strategies in the event of symptomatic IAFE. A survey was sent to all members of the MAHORN group. Surveys collected data on general hip arthroscopy settings, including pump pressure and frequency of different hip arthroscopies performed, as well as details on cases of symptomatic IAFE. Responses to the survey were documented and analyzed. Fifteen hip arthroscopists from the MAHORN group were surveyed. A total of 25,648 hip arthroscopies between 1984 and 2010 were reviewed. Arthroscopic procedures included capsulotomies, labral reattachment after acetabuloplasty, peripheral compartment arthroscopy, and osteoplasty of the femoral head-neck junction. Of the arthroscopists, 7 (47%) had 1 or more cases of IAFE (40 cases reported). The prevalence of IAFE in this study was 0.16% (40 of 25,650). Significant risk factors associated with IAFE were higher arthroscopic fluid pump pressure (P = .004) and concomitant iliopsoas tenotomy (P arthroscopy is a rare occurrence, with an approximate prevalence of 0.16%. Prevention of IAFE should include close intraoperative and postoperative monitoring of abdominal distention, core body temperature, and hemodynamic stability. Concomitant iliopsoas tenotomy and high pump pressures may be risk factors leading to symptomatic IAFE. Level IV, therapeutic case series. Copyright © 2012 Arthroscopy Association of North America.

1989-01-01

The intergalactic cloud of neutral hydrogen in the M96 group are examined for signs of emission over a wide range of frequencies, from radio waves to X rays. Past or present stellar activity in the gas might have been expected to produce detectable visual infrared, CO, OH, or radio recombination-line emission. None was detected. The limits are used to study physical conditions in the intergalactic gas. In particular, B and V band limits on starlight and IRAS limits on the presence of dust strongly constrain the presence of stars or stellar by-products. However, given the uncertainties about physical conditions in the intergalactic environment, it is difficult to rule out entirely the presence of stellar-processed materials. Results of neutral hydrogen mapping from a large-scale survey of the intergalactic cloud and surrounding region are also presented. These observations confirm that the gas is confined to a large ringlike structure. The simplest interpretation remains that the intergalactic gas in Leo is primordial. 36 references

National survey provides average power quality profiles for different customer groups

International Nuclear Information System (INIS)

Hughes, B.; Chan, J.

1996-01-01

A three year survey, beginning in 1991, was conducted by the Canadian Electrical Association to study the levels of power quality that exist in Canada, and to determine ways to increase utility expertise in making power quality measurements. Twenty-two utilities across Canada were involved, with a total of 550 sites being monitored, including residential and commercial customers. Power disturbances, power outages and power quality were recorded for each site. To create a group average power quality plot, the transient disturbance activity for each site was normalized to a per channel, per month basis and then divided into a grid. Results showed that the average power quality provided by Canadian utilities was very good. Almost all the electrical disturbance within a customer premises were created and stayed within those premises. Disturbances were generally beyond utility control. Utilities could, however, reduce the amount of time the steady-state voltage exceeds the CSA normal voltage upper limit. 5 figs

OAPS’ ACTIVITY IN THE LABOUR MARKET IN THE CONTEXT OF SURVEY RESEARCH

Directory of Open Access Journals (Sweden)

Władysława Łuczka-Bakuła

2013-12-01

Full Text Available A great deal of attention has been paid in recent years not merely to young people’s activity in the labour market, but also to the vocational involvement of elderly people. The traditional attitude towards the contemporary labour market results from the social and economic transformation, but also demographic changes and, the process of population ageing. It is thus a vital issue. A growing number of elderly people contributes to the increase in the number of beneficiaries, which is reflected in lower labour force participation and, consequently, may lead to a deterioration of production capacity of economy. On the one hand, higher pensions may be viewed as higher incomes of pensioners, but on the other hand, they constitute an extra burden for public expenses. Conversely, lower pensions may not merely result in increased activity in the labour market and higher incomes, but also be linked with an increase in social welfare expenditure. The article discusses the results of survey research conducted between 2009 and 2010 in a group of pensioners. The research shows that over a half of the surveyed OAPs were active in the labour market and their activity was mainly induced by their financial situation. 

Group-Based Active Learning of Classification Models.

Luo, Zhipeng; Hauskrecht, Milos

2017-05-01

Learning of classification models from real-world data often requires additional human expert effort to annotate the data. However, this process can be rather costly and finding ways of reducing the human annotation effort is critical for this task. The objective of this paper is to develop and study new ways of providing human feedback for efficient learning of classification models by labeling groups of examples. Briefly, unlike traditional active learning methods that seek feedback on individual examples, we develop a new group-based active learning framework that solicits label information on groups of multiple examples. In order to describe groups in a user-friendly way, conjunctive patterns are used to compactly represent groups. Our empirical study on 12 UCI data sets demonstrates the advantages and superiority of our approach over both classic instance-based active learning work, as well as existing group-based active-learning methods.

Results of the survey activities and mobile gamma scanning in Monticello, Utah

Little, C.A.; Berven, B.A.

1985-11-01

The town of Monticello, Utah, was once the site of an active mill which processed vanadium ore (1942 to 1948), and uranium ore (1948 to 1960). Properties in the vicinity of that mill have become contaminated with radioactive material from ore processing. The Radiological Survey Activities (RASA) group at Oak Ridge National Laboratory (ORNL) was requested by the Division of Remedial Action Projects (DRAP) in the Department of Energy (DOE) to: (1) identify potentially contaminated properties; (2) assess natural background radiation levels; and (3) rapidly assess the magnitude, extent, and type (i.e. ore, tailings, etc.) of contamination present on these properties (if any). This survey was conducted by RASA during April 1983. In addition to the 114 properties previously identified from historical information, the ORNL mobile gamma scanning van located 36 new properties exhibiting anomalous gamma radiation levels. Onsite surveys were conducted on 145 of the 150 total properties identified either historically or with the gamma scanning van. Of these 145 properties, 122 of them appeared to have some type of contaminated material present on them; however, only 48 appeared to be contaminated to the extent where they were in excess of Environmental Protection Agency (EPA) criteria (40 CFR 192). Twenty-one other properties were recommended for additional investigation (indoor gamma scanning and radon daughter measurements); of these, only ten required further analysis. This report provides the detailed data and analyses related to the radiological survey efforts performed by ORNL in Monticello, Utah

GROUP FINDING IN THE STELLAR HALO USING PHOTOMETRIC SURVEYS: CURRENT SENSITIVITY AND FUTURE PROSPECTS

International Nuclear Information System (INIS)

Sharma, Sanjib; Johnston, Kathryn V.; Majewski, Steven R.; Bullock, James; Munoz, Ricardo R.

2011-01-01

The Sloan Digital Sky Survey (SDSS) and the Two Micron All Sky Survey (2MASS) provided the first deep and global photometric catalogs of stars in our halo and not only clearly mapped its structure but also demonstrated the ubiquity of substructure within it. Future surveys promise to push such catalogs to ever increasing depths and larger numbers of stars. This paper examines what can be learned from current and future photometric databases using group-finding techniques. We compare groups recovered from a sample of M-giants from 2MASS with those found in synthetic surveys of simulated ΛCDM stellar halos that were built entirely from satellite accretion events and demonstrate broad consistency between the properties of the two sets. We also find that these recovered groups are likely to represent the majority of high-luminosity (L > 5 x 10 6 L sun ) satellites accreted within the last 10 Gyr and on orbits with apocenters within 100 kpc. However, the sensitivity of the M-giant survey to accretion events that were either ancient from low-luminosity objects or those on radial orbits is limited because of the low number of stars, bias toward high-metallicity stars, and the shallow depth (distance explored only out to 100 kpc from the Sun). We examine the extent to which these limitations are addressed by current and future surveys, in particular catalogs of main-sequence turnoff (MSTO) stars from SDSS and the Large Synoptic Survey Telescope (LSST), and of RR Lyrae stars from LSST or PanSTARRS. The MSTO and RR Lyrae surveys are more sensitive to low-luminosity events (L ∼ 10 5 L sun or less) than the 2MASS M-giant sample. Additionally, RR Lyrae surveys, with superior depth, are also good at detecting events on highly eccentric orbits whose debris tends to lie beyond 100 kpc. When combined we expect these photometric surveys to provide a comprehensive picture of the last 10 Gyr of Galactic accretion. Events older than this are too phase mixed to be discovered. Pushing

In Massachusetts, physician groups' performance on validated surveys of patient experience has been publicly reported since 2006. Groups also receive detailed reports of their own performance, but little is known about how physician groups have responded to these reports. To examine whether and how physician groups are using patient experience data to improve patient care. During 2008, we conducted semi-structured interviews with the leaders of 72 participating physician groups (out of 117 groups receiving patient experience reports). Based on leaders' responses, we identified three levels of engagement with patient experience reporting: no efforts to improve (level 1), efforts to improve only the performance of low-scoring physicians or practice sites (level 2), and efforts to improve group-wide performance (level 3). Groups' level of engagement and specific efforts to improve patient care. Forty-four group leaders (61%) reported group-wide improvement efforts (level 3), 16 (22%) reported efforts to improve only the performance of low-scoring physicians or practice sites (level 2), and 12 (17%) reported no performance improvement efforts (level 1). Level 3 groups were more likely than others to have an integrated medical group organizational model (84% vs. 31% at level 2 and 33% at level 1; P customer service. The most commonly reported improvement initiatives were changing office workflow, providing additional training for nonclinical staff, and adopting or enhancing an electronic health record. Despite statewide public reporting, physician groups' use of patient experience data varied widely. Integrated organizational models were associated with greater engagement, and efforts to enhance clinicians' interpersonal skills were uncommon, with groups predominantly focusing on office workflow and support staff.

Psycho-social picture of sexually active adolescent girls: Results of research survey

Directory of Open Access Journals (Sweden)

Stanković Biljana

2004-01-01

Full Text Available In a demographic sense, adolescents are a population group which is yet to take part in birth giving. Therefore, their sexual behavior and especially sexual activity at early ages which is not only unfavorable from the aspect of the individual, meaning risk for psycho-physical health, but from the aspect of society as well, as regards population fertility, deserves special attention. This paper shows the results of in-depth research carried out in Belgrade from September 2001 to October 2002 with an aim to establish which factors determine a young person, of sixteen years old or younger, to become sexually active. It was carried out on a sample of 111 adolescent girls between 14 and 20 years old which turned to the Republic Family Planning Center Youth Counseling Clinic of the Institute for Mother and Child Health Care of Serbia. The research showed that sexual experience, realized at an early age was an integral part of development and maturing for the largest number of surveyed girls. In the largest number of cases it was a positive experience, induced by love and experienced with a partner, mainly of the same age, with which they were in a longer, stable relationship. Nevertheless, it could be concluded from the results obtained by the research that the surveyed girls could have more easily and efficiently solved their problems and dilemmas regarding sexuality had they had the possibility to obtain a better insight into their personal feelings and feelings of others at the right time, as well as developed social experience and experience in mastering control of their impulses. With a certain number of surveyed girls that would have meant a delay in their sexual activities to a later age. This also refers to the prevention of other risky behavior such as use of alcohol and drugs, which also have an influence on changing sexual behavior, making it more risky. It is important to stress that the surveyed adolescent girls themselves recognized the

Durations and domains of daily aerobic activity: evidence from the 2010 Canadian time-use survey.

Science.gov (United States)

Millward, Hugh; Spinney J, E L; Scott, Darren

2014-07-01

This study employs national time-diary data to evaluate how much aerobic activity Canadians engage in on a daily basis, how that activity is apportioned by activity domain, and how subgroups within the population vary in their aerobic attainment. The study employs time-use data from the 2010 General Social Survey of Canada, for 15,390 respondents aged 15 and older. To estimate effort levels, the authors harmonized survey codes with those in the Compendium of Physical Activities. Aerobic activity was defined as moderate or vigorous effort at 3.5 Metabolic Equivalent of Task (MET) or higher. Among the 4 activity domains, aerobic participation is highest in leisure activities, followed by chores, paid work, and active transportation (AT). Only a minority (42%) of respondents recorded at least 20 mins/day of aerobic activity. Aerobic totals were particularly low for women and those in poor or fair health, and low for students, 15- to 24-year-olds, and those residing in Quebec, Ontario, and larger cities. The majority of Canadian adults are failing to meet recommended aerobic activity levels. However, there is considerable opportunity to increase aerobic participation for some groups, particularly women and young adults, especially in the leisure and AT domains.

Does Dog Walking Predict Physical Activity Participation: Results From a National Survey.

Science.gov (United States)

Richards, Elizabeth A

2016-05-01

The purpose of this study is to: (1) identify characteristics associated with dog owners who walk their dog, (2) describe the frequency and duration of walking the dog, and (3) determine whether dog owners who walk their dog participate in more physical activity than dog owners who do not walk their dog and non-dog owners. A cross-sectional study design was used. The study setting was nationwide. Adults (n = 4010) participating in the 2005 ConsumerStyles mail-panel survey were the study subjects. Measures used were demographic, physical activity, dog ownership, and dog walking questions from the 2005 ConsumerStyles mail-panel survey. Chi-square tests and analyses of variance were conducted to examine participant characteristics associated with dog walking and to describe the frequency and duration of dog walking. Analysis of covariance was used to determine whether dog owners who walk their dog participate in more physical activity than dog owners who do not walk their dog and non-dog owners. Among dog owners, 42% reported some dog walking in a typical week. Dog owners walked their dog an average 4.3 ± 0.1 times and 128.8 ± 5.6 minutes per week. There were no significant differences in weekly minutes of moderate or vigorous physical activity across the dog-ownership and dog walking groups. Most dog owners did not walk their dog. Dog owners were not more active than non-dog owners, except when considering the activity obtained via dog walking. © The Author(s) 2016.

- Patients with rare tumors have difficulty finding reliable information about their disease. Facebook patient support groups allow patients to educate one another. - To investigate how these patients perceive the value of pathologists, both in Facebook groups and real-world patient care. - Survey links were posted in 12 Facebook patient groups: 6 with an active pathologist member (angiosarcoma, epithelioid hemangioendothelioma, epithelioid sarcoma, dermatofibrosarcoma protuberans [×2], and desmoid fibromatosis), and 6 without "active" pathologist involvement (aggressive angiomyxoma, chondrosarcoma, Ewing sarcoma, leiomyosarcoma, liposarcoma, and osteosarcoma). - A total of 542 people responded (403 were patients): 264 from groups with a pathologist, and 278 from groups without active pathologist involvement. Of groups with an active pathologist, respondents agreed the pathologist's posts helped them better understand their disease (107 of 119; 90%) and relieved some of their disease-related anxiety (92 of 119; 77%). And for these groups 98% (117 of 119) of respondents agreed that having a pathologist in their group was a good thing; 83% (192 of 232) wanted more pathologists involved. More respondents from groups with an active pathologist (219 of 236; 93%) than without one (215 of 252; 85%) agreed: "pathologists are an important part of the patient care team for patients with cancer and other rare tumors" ( P = .008). - This study is the first to evaluate the impact of pathologist interaction with Facebook patient support groups and to assess perceptions about the specialty of pathology from a large group of patients with rare tumors. Pathologist involvement in Facebook patient groups appears to positively influence patient perception of the importance of pathologists. We hope these data will encourage more pathologists to participate in Facebook patient support groups.

The burden of chronic respiratory disease (CRD) is alarming. International studies suggest that women with CRD are undersurveyed and underdiagnosed by physicians worldwide. It is unclear what the prevalence of CRD is in the general population of Syria, particularly among women, since there has never been a survey on CRD in this nation. The purpose of this study was to investigate the impact of different patterns of smoking on CRD in women. We extracted data on smoking patterns and outcome in women from the Global Alliance Against Chronic Respiratory Diseases survey. Using spirometric measurements before and after the use of inhaled bronchodilators, we tracked the frequency of CRD in females active and passive narghile or cigarette smokers presenting to primary care. We administered the questionnaire to 788 randomly selected females seen during 1 week in the fiscal year 2009-2010 in 22 primary care centers in six different regions of Syria. Inclusion criteria were age >6 years, presenting for any medical complaint. In this cross-sectional study, three groups of female subjects were evaluated: active smokers of cigarettes, active smokers of narghiles, and passive smokers of either cigarettes or narghiles. These three groups were compared to a control group of female subjects not exposed to active or passive smoking. Exposure to active cigarette smoke but not narghile smoke was associated with doctor-diagnosed chronic obstructive pulmonary disease (COPD). However, neither cigarette nor narghile active smoking was associated with increased incidence of spirometrically diagnosed COPD. Paradoxically, exposure to passive smoking of either cigarettes or narghiles resulted in association with airway obstruction, defined as forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) < 70% according to the Global initiative for chronic Obstructive Lung Disease criteria; association with FEV1 < 80% predicted, evidencing moderate to severe GOLD spirometric grade

The population of nearby dwarf galaxies in the Local Group constitutes a complete galactic environment, perfect suited for studying the connection between stellar populations and galaxy evolution. In this study, we are conducting an optical monitoring survey of the majority of dwarf galaxies in the Local Group, with the Isaac Newton Telescope (INT), to identify long period variable stars (LPVs). These stars are at the end points of their evolution and therefore their luminosity can be directly translated into their birth masses; this enables us to reconstruct the star formation history. By the end of the monitoring survey, we will have performed observations over ten epochs, spaced approximately three months apart, and identified long-period, dust-producing AGB stars; five epochs of data have been obtained already. LPVs are also the main source of dust; in combination with Spitzer Space Telescope images at mid-IR wavelengths we will quantify the mass loss, and provide a detailed map of the mass feedback into the interstellar medium. We will also use the amplitudes in different optical passbands to determine the radius variations of the stars, and relate this to their mass loss. (paper)

The population of nearby dwarf galaxies in the Local Group constitutes a complete galactic environment, perfect suited for studying the connection between stellar populations and galaxy evolution. In this study, we are conducting an optical monitoring survey of the majority of dwarf galaxies in the Local Group, with the Isaac Newton Telescope (INT), to identify long period variable stars (LPVs). These stars are at the end points of their evolution and therefore their luminosity can be directly translated into their birth masses; this enables us to reconstruct the star formation history. By the end of the monitoring survey, we will have performed observations over ten epochs, spaced approximately three months apart, and identified long-period, dust-producing AGB stars; five epochs of data have been obtained already. LPVs are also the main source of dust; in combination with Spitzer Space Telescope images at mid-IR wavelengths we will quantify the mass loss, and provide a detailed map of the mass feedback into the interstellar medium. We will also use the amplitudes in different optical passbands to determine the radius variations of the stars, and relate this to their mass loss.

The number of local, national and international networks of online environmental sensors are rapidly increasing. Where environmental data are made available online for public consumption, there is a need to advance our understanding of the relationships between the supply of and the different demands for such information. Understanding how individuals and groups of users are using online information resources may provide valuable insights into their activities and decision making. As part of the 'dot.rural wikiRivers' project we investigated the potential of web analytics and an online survey to generate insights into the use of a national network of river level data from across Scotland. These sources of online information were collected alongside phone interviews with volunteers sampled from the online survey, and interviews with providers of online river level data; as part of a larger project that set out to help improve the communication of Scotland's online river data. Our web analytics analysis was based on over 100 online sensors which are maintained by the Scottish Environmental Protection Agency (SEPA). Through use of Google Analytics data accessed via the R Ganalytics package we assessed: if the quality of data provided by Google Analytics free service is good enough for research purposes; if we could demonstrate what sensors were being used, when and where; how the nature and pattern of sensor data may affect web traffic; and whether we can identify and profile these users based on information from traffic sources. Web analytics data consists of a series of quantitative metrics which capture and summarize various dimensions of the traffic to a certain web page or set of pages. Examples of commonly used metrics include the number of total visits to a site and the number of total page views. Our analyses of the traffic sources from 2009 to 2011 identified several different major user groups. To improve our understanding of how the use of this national

This study aims to evaluate compositional factors, including collaborative age and size, and community, policy, and political engagement activities that may influence collaboratives' effectiveness in advancing environmental improvements and policies for active living. Structured interviews were conducted with collaboratives' coordinators. Survey items included organizational composition, community, policy, and political engagement activities and reported environmental improvements and policy change. Descriptive statistics and multivariate models were used to investigate these relationships. Environmental improvement and policy change scores reflecting level of collaborative effectiveness across 8 strategy areas (eg, parks and recreation, transit, streetscaping, and land redevelopment). Fifty-nine collaborative groups participated in the interview, representing 22 states. Groups have made progress in identifying areas for environmental improvements and in many instances have received funding to support these changes. Results from multivariate models indicate that engagement in media communication and advocacy was statistically correlated with higher levels of environmental improvement, after adjusting for age of group and area poverty levels (P engagement activities may represent important levers for achieving structural and policy changes to the built environment.

To gain some insight into how various behavioral (lifestyle) factors influence sleep duration, by investigation of the relationship of sleep time to waking activities using the American Time Use Survey (ATUS). Cross-sectional data from ATUS, an annual telephone survey of a population sample of US citizens who are interviewed regarding how they spent their time during a 24-hour period between 04:00 on the previous day and 04:00 on the interview day. Data were pooled from the 2003, 2004, and 2005 ATUS databases involving N=47,731 respondents older than 14 years of age. N/A. Adjusted multiple linear regression models showed that the largest reciprocal relationship to sleep was found for work time, followed by travel time, which included commute time. Only shorter than average sleepers (socializing, relaxing, and engaging in leisure activities, while both short ( or =8.5 h) watched more TV than the average sleeper. The extent to which sleep time was exchanged for waking activities was also shown to depend on age and gender. Sleep time was minimal while work time was maximal in the age group 45-54 yr, and sleep time increased both with lower and higher age. Work time, travel time, and time for socializing, relaxing, and leisure are the primary activities reciprocally related to sleep time among Americans. These activities may be confounding the frequently observed association between short and long sleep on one hand and morbidity and mortality on the other hand and should be controlled for in future studies.

Regular physical activity can have a positive effect on health at any age. Today's lifestyles, however, can often be characterised as sedentary. Therefore, the promotion of physical activity and sports has become an integral part of public health measures. The representative data of adults aged 18 to 79 years in Germany obtained from the "German Health Interview and Examination Survey for Adults" (DEGS1) provide an overview of self-estimated current physical activity behaviour. The results show that one third of the adult population claims to pay close attention to reaching a sufficient level of physical activity and one fourth participates in sports for at least 2 h/week on a regular basis. Thus, the percentage of adults regularly engaged in sports has increased compared to the previous "German National Health Interview and Examination Survey 1998". Still, four out of five adults do not achieve at least 2.5 h/week of moderate-intensity physical activity as recommended by the World Health Organisation. Consequently, future individual-level and population-level interventions should focus on target group-specific measures while continuing to promote regular physical activity in all segments of the population.

There are no guidelines for when surgeons should allow patients to return to sports and athletic activities after spinal fusion for adolescent idiopathic scoliosis (AIS). Current recommendations are based on anecdotal reports and a survey performed more than a decade ago in the era of first/second-generation posterior implants. To identify current recommendations for return to sports and athletic activities after surgery for AIS. Questionnaire-based survey. Adolescent idiopathic scoliosis after corrective surgery. Type and time to return to sports. A survey was administered to members of the Spinal Deformity Study Group. The survey consisted of surgeon demographic information, six clinical case scenarios, three different construct types (hooks, pedicle screws, hybrid), and questions regarding the influence of lowest instrumented vertebra (LIV) and postoperative physical therapy. Twenty-three surgeons completed the survey, and respondents were all experienced expert deformity surgeons. Pedicle screw instrumentation allows earlier return to noncontact and contact sports, with most patients allowed to return to running by 3 months, both noncontact and contact sports by 6 months, and collision sports by 12 months postoperatively. For all construct types, approximately 20% never allow return to collision sports, whereas all surgeons allow eventual return to contact and noncontact sports regardless of construct type. In addition to construct type, we found progressively distal LIV resulted in more surgeons never allowing return to collision sports, with 12% for selective thoracic fusion to T12/L1 versus 33% for posterior spinal fusion to L4. Most respondents also did not recommend formal postoperative physical therapy (78%). Of all surgeons surveyed, there was only one reported instrumentation failure/pullout without neurologic deficit after a patient went snowboarding 2 weeks postoperatively. Modern posterior instrumentation allows surgeons to recommend earlier return

For the last two decades, neutrino physics has been producing major discoveries including neutrino oscillations. These results gave clear confirmation that active neutrinos oscillate and therefore have mass with three different mass states. This is a very important result showing that the Minimal Standard Model is incomplete and requires an extension which is not yet known. The neutrino research field is very broad and active, at the frontier of today's particle physics. The Neutrino Research Group (GDR) was created in January 2005 with the aim of gathering CEA and CNRS research teams working on Neutrino Physics on experimental or theoretical level. This document is the 2011-2014 activity report of the research group, ten years after its creation. It presents the results of the 5 working groups: 1 - Determination of neutrino parameters; 2 - Physics beyond the standard model; 3 - Neutrinos in the universe; 4 - Accelerators, detection means, R and D and valorisation; 5 - Common tools to all working groups. The research group structure, participating laboratories and teams and the neutrino physics road-map are presented in appendixes

2016-01-01

Purpose: To evaluate the reliability of RPN (Risk Priority Number) decided by expert group and to provide preliminary data for adapting FMEA in Korea. Methods: 1163 Incidents reported in ROSIS for 11 years were used as a real data to be compared with, and were categorized into 146 items. The questionnaire was composed of the 146 items and respondents had to valuate ‘occurrence (O)’, ‘severity (S)’, ‘detectability (D)’ of each item on a scale from 1 to 10 according to the proposed AAPM TG-100 rating scales. 19 medical physicists from 19 different organizations in Korea had participated in the survey. Because the number of ROSIS items was not evenly spread enough to be classified into 10 grades, 1–5 scale was chosen instead of 1–10 and survey result was also fit to 5 grades to compare. Results: The average O,S,D were 1.77, 3.50, 2.13, respectively and the item which had the highest RPN(32) was ‘patient movement during treatment’ in the survey. When comparing items ranked in the top 10 of each survey(O) and ROSIS database, two items were duplicated and ‘Simulation’ and ’Treatment’ were the most frequently ranked RT process in top 10 of survey and ROSIS each. The Chronbach α of each RT process were ranged from 0.74 to 0.99 and p-value was <0.001. When comparing O*D, the average difference was 1.4. Conclusion: This work indicates the deviation between actual risk and expectation. Considering that the respondents were Korean and ROSIS is mainly composed of incidents happened in European countries and some of the top 10 items of ROSIS cannot be applied in radiotherapy procedure in Korea, the deviation could have been came from procedural difference. Moreover, if expert group was consisted of experts from various parts, expectation might have been more accurate. Therefore, further research on radiotherapy risk estimation is needed.

Full Text Available Patient-centered clinical trial design and execution is becoming increasingly important. No best practice guidelines exist despite a key stakeholder declaration to create more effective engagement models. This study aims to gain a better understanding of attitudes and practices for engaging patient groups so that actionable recommendations may be developed.Individuals from industry, academic institutions, and patient groups were identified through Clinical Trials Transformation Initiative and Drug Information Association rosters and mailing lists. Objectives, practices, and perceived barriers related to engaging patient groups in the planning, conduct, and interpretation of clinical trials were reported in an online survey. Descriptive and inferential statistical analysis of survey data followed a literature review to inform survey questions.Survey respondents (n = 179 valued the importance of involving patient groups in research; however, patient group respondents valued their contributions to research protocol development, funding acquisition, and interpretation of study results more highly than those contributions were valued by industry and academic respondents (all p < .001.

We use the first 25% of the DEEP2 Galaxy Redshift Survey spectroscopic data to identify groups and clusters of galaxies in redshift space. The data set contains 8370 galaxies with confirmed redshifts in the range 0.7 {<=} z {<=} 1.4, over one square degree on the sky. Groups are identified using an algorithm (the Voronoi-Delaunay Method) that has been shown to accurately reproduce the statistics of groups in simulated DEEP2-like samples. We optimize this algorithm for the DEEP2 survey by applying it to realistic mock galaxy catalogs and assessing the results using a stringent set of criteria for measuring group-finding success, which we develop and describe in detail here. We find in particular that the group-finder can successfully identify {approx}78% of real groups and that {approx}79% of the galaxies that are true members of groups can be identified as such. Conversely, we estimate that {approx}55% of the groups we find can be definitively identified with real groups and that {approx}46% of the galaxies we place into groups are interloper field galaxies. Most importantly, we find that it is possible to measure the distribution of groups in redshift and velocity dispersion, n({sigma}, z), to an accuracy limited by cosmic variance, for dispersions greater than 350 km s{sup -1}. We anticipate that such measurements will allow strong constraints to be placed on the equation of state of the dark energy in the future. Finally, we present the first DEEP2 group catalog, which assigns 32% of the galaxies to 899 distinct groups with two or more members, 153 of which have velocity dispersions above 350 km s{sup -1}. We provide locations, redshifts and properties for this high-dispersion subsample. This catalog represents the largest sample to date of spectroscopically detected groups at z {approx} 1.

This work aims at presenting the ongoing research activities carried out in Working Group 2 'GPR surveying of pavements, bridges, tunnels and buildings; underground utility and void sensing' of the COST (European COoperation in Science and Technology) Action TU1208 'Civil Engineering Applications of Ground Penetrating Radar' (www.GPRadar.eu). The principal goal of the COST Action TU1208 is to exchange and increase scientific-technical knowledge and experience of Ground Penetrating Radar (GPR) techniques in civil engineering, whilst simultaneously promoting throughout Europe the effective use of this safe and non-destructive technique in the monitoring of infrastructures and structures. Four Working Groups (WGs) carry out the research activities. WG1 focuses on the development of innovative GPR equipment dedicated for civil engineering applications. WG2 deals with the development of guidelines and protocols for the surveying, through the use of a GPR system, of transport infrastructure and buildings, as well as for the sensing of utilities and voids. WG3 deals with the development of electromagnetic forward and inverse scattering methods, for the characterization of GPR scenarios, as well as with data- processing algorithms for the elaboration of the data collected during GPR surveys. WG4 is concerned with the use of GPR in fields different from the civil engineering, as well as with the integration of GPR with other non-destructive testing techniques. Each WG includes several Projects. WG2 includes five Projects. Project 2.1 focuses on outlining 'Innovative inspection procedures for effective GPR surveying of critical transport infrastructures (pavements, bridges and tunnels).' Project 2.2 is concerned with the development of 'Innovative inspection procedures for effective GPR surveying of buildings.' Project 2.3 deals with identifying 'Innovative inspection procedures for effective GPR sensing and mapping of underground utilities and voids, with a focus to urban

Thousands of people treated in primary care are currently experiencing chronic pain (CP), for which management is often inadequate. In Quebec, nurses in family medicine groups (FMGs) play a key role in the management of chronic health problems. The present study aimed to describe the activities performed by FMG nurses in relation to CP management and to describe barriers to those activities. A descriptive correlational cross-sectional postal survey was used. The accessible population includes FMG nurses on the Ordre des infirmières et infirmiers du Québec list. All nurses on the list who provided consent to be contacted at home for research purposes were contacted. A self-administered postal questionnaire (Pain Management Activities Questionnaire) was completed by 53 FMG nurses. Three activities most often performed by nurses were to establish a therapeutic relationship with the client; discuss the effectiveness of therapeutic measures with the physician; and conduct personalized teaching for the patient. The average number of individuals seen by interviewed nurses that they believe suffer from CP was 2.68 per week. The lack of knowledge of possible interventions in pain management (71.7%) and the nonavailability of information on pain management (52.8%) are the main barriers perceived by FMG nurses. FMG nurses are currently performing few activities in CP management. The nonrecognition of CP may explain this situation.

Online social networking is increasingly being used among medical practitioners. However, few studies have evaluated its use in therapeutic endoscopy. Here, we aimed to analyze the shared topics and activities of a group of endoscopic retrograde cholangiopancreatography (ERCP) doctors in a social networking-based endoscopic retrograde cholangiopancreatography discussion group (EDG). Six ERCP trainers working in Xijing Hospital and 48 graduated endoscopists who had finished ERCP training in the same hospital were invited to join in EDG. All group members were informed not to divulge any private information of patients when using EDG. The activities of group members on EDG were retrospectively extracted. The individual data of the graduated endoscopists were collected by a questionnaire. From June 2014 to May 2015, 6924 messages were posted on EDG, half of which were ERCP related. In total, 214 ERCP-related topics were shared, which could be categorized into three types: sharing experience/cases (52.3%), asking questions (38.3%), and sharing literatures/advances (9.3%). Among the 48 graduated endoscopists, 21 had a low case volume of less than 50 per year and 27 had a high volume case volume of 50 or more. High-volume graduated endoscopists posted more ERCP-related messages (P=0.008) and shared more discussion topics (P=0.003) compared with low-volume graduated endoscopists. A survey showed that EDG was useful for graduated endoscopists in ERCP performance and management of post-ERCP complications, etc. A wide range of ERCP-related topics were shared on the social networking-based EDG. The ERCP-related behaviors on EDG were more active in graduated endoscopists with an ERCP case volume of more than 50 per year.

There is an ∼150 km s{sup –1} discrepancy between the measured motion of the Local Group (LG) of galaxies with respect to the cosmic microwave background and the linear theory prediction based on the gravitational force field of the large-scale structure in full-sky redshift surveys. We perform a variety of tests which show that the LG motion cannot be recovered to better than 150-200 km s{sup –1} in amplitude and within ≈10° in direction. The tests rely on catalogs of mock galaxies identified in the Millennium simulation using semi-analytic galaxy formation models. We compare these results to the K{sub s} = 11.75 Two-Mass Galaxy Redshift Survey, which provides the deepest and most complete all-sky spatial distribution of galaxies with spectroscopic redshifts available thus far. In our analysis, we use a new concise relation for deriving the LG motion and bulk flow from the true distribution of galaxies in redshift space. Our results show that the main source of uncertainty is the small effective depth of surveys like the Two-Mass Redshift Survey (2MRS), which prevents a proper sampling of the large-scale structure beyond ∼100 h {sup –1} Mpc. Deeper redshift surveys are needed to reach the 'convergence scale' of ≈250 h {sup –1} Mpc in a ΛCDM universe. Deeper surveys would also mitigate the impact of the 'Kaiser rocket' which, in a survey like 2MRS, remains a significant source of uncertainty. Thanks to the quiet and moderate density environment of the LG, purely dynamical uncertainties of the linear predictions are subdominant at the level of ∼90 km s{sup –1}. Finally, we show that deviations from linear galaxy biasing and shot noise errors provide a minor contribution to the total error budget.

Survey as a group interactive teaching technique

Full Text Available Smooth running of the educational process and the results depend a great deal on the methods used. The methodology of teaching offers a great variety of teaching techniques that the teacher can make use of in the teaching/learning process. Such techniques as brainstorming, the cube, KLW, case study, Venn diagram, and many other are familiar to the teachers and they use them effectively in the classroom. The present article proposes a technique called ‘survey’, which has been successfully used by the author as a student-centered speaking activity in foreign language classes. It has certain advantages especially if used in large groups. It can be adapted for any other discipline in the case when the teacher wishes to offer the students space for cooperative activity and creativity.

Chapman, K.; James, S.

2016-01-01

Aim: The aims of the survey were to check that group pre-radiotherapy information sessions met patients' needs. The use of virtual technology (VT) through Patient Education And Radiotherapy Learning (PEARL) was incorporated part way through the survey period. Methods: Patients attending group pre-radiotherapy information sessions led by assistant practitioners between March and December 2014 were asked to complete questionnaires after they had attended at least five radiotherapy sessions. Key results: 305 patients attended sessions during the survey period. 129 questionnaires were distributed with 103 returned, resulting in an 80% response rate (Overall rate 34%). 102 (99%) patients responded that they were happy and comfortable to receive their radiotherapy information in a group setting. The majority of patients responded that they felt no additional information should be included. Conclusions and recommendations: The survey highlighted that almost all patients were happy to receive their information in a group setting. Patients attending non PEARL and PEARL sessions indicated high satisfaction levels with no notable differences between the groups. This has allayed MVCC staffs' original concerns that patients may find the use of VT as frightening in patient information sessions, so the centre is now confident to incorporate it in the future. The implementation of these sessions has seemed to be both feasible and an efficient use of staff time. All patients referred for radical breast radiotherapy are now invited to attend. It is recommended that regular patient experience surveys are conducted in the future to ensure they continue to meet patients' needs. - Highlights: • 102 (99%) patients responded happy to receive their information in a group setting. • 86 (83%) patients responded they felt no additional information should be included. • 58 (56%) patients provided complimentary comments about the sessions.

The measurement of patient satisfaction is crucial to enhancing customer service and competitive advantage in the health-care industry. While there are numerous approaches to such measurement, this paper provides a case study which compares and contrasts patient and staff perceptions of customer service using both survey and focus group data. Results indicate that there is a high degree of correlation between staff and patient perceptions of customer service based on both survey and focus group data. However, the staff and patient subgroups also provided complementary information regarding patient perceptions of their service experience. Staff members tended to have more negative perceptions of service attributes than did the patients themselves. The focus group results provide complementary information to survey results in terms of greater detail and more managerially relevant information. While these results are derived from a pilot study, they suggest that diversification of data sources beyond patient surveys may enhance the utility of customer service information. If further research can affirm these findings, they create exciting possibilities for gathering valid, reliable and cost-effective customer service information.

2016-12-01

This study used the 2010 Health of Houston Survey to examine the physical activity of Asian American adults living in Houston, Texas. Multivariate regression models were conducted to examine the number of moderate leisure physical activity days in the past week and likelihood of having sufficient levels of physical activity. The results showed that Asians were among the least physically active of the major racial/ethnic groups. Most notably, Asians were less likely than whites to have sufficient levels of physical activity and had similarly lower expected numbers of physical activity minutes and days. Within the Asian American population, Vietnamese adults had more physical activity minutes and days than their Chinese counterparts-after controlling for other sociodemographic and health factors. Age- and gender-adjusted rates suggested a significant gender disparity among the Vietnamese and South Asian adults (less so for the Chinese adults), but this varied across different age groups. Several factors emerged as significant predictors of physical activity for Asian Americans, including age, immigration status, speaking a non-English language at home, marital status, and neighborhood incivilities. Findings highlight the need for targeted, culturally appropriate interventions to promote physical activity in Asian American communities.

Discriminative latent models for recognizing contextual group activities.

In this paper, we go beyond recognizing the actions of individuals and focus on group activities. This is motivated from the observation that human actions are rarely performed in isolation; the contextual information of what other people in the scene are doing provides a useful cue for understanding high-level activities. We propose a novel framework for recognizing group activities which jointly captures the group activity, the individual person actions, and the interactions among them. Two types of contextual information, group-person interaction and person-person interaction, are explored in a latent variable framework. In particular, we propose three different approaches to model the person-person interaction. One approach is to explore the structures of person-person interaction. Differently from most of the previous latent structured models, which assume a predefined structure for the hidden layer, e.g., a tree structure, we treat the structure of the hidden layer as a latent variable and implicitly infer it during learning and inference. The second approach explores person-person interaction in the feature level. We introduce a new feature representation called the action context (AC) descriptor. The AC descriptor encodes information about not only the action of an individual person in the video, but also the behavior of other people nearby. The third approach combines the above two. Our experimental results demonstrate the benefit of using contextual information for disambiguating group activities.

Blood-group-Ii-active gangliosides of human erythrocyte membranes

More than ten new types of gangliosides, in addition to haematoside and sialosylparagloboside, were isolated from human erythrocyte membranes. These were separated by successive chromatographies on DAEA-Sephadex, on porous silica-gel columns and on thin-layer silica gel as acetylated compounds. Highly potent blood-group-Ii and moderate blood-group-H activities were demonstrated in some of the ganglioside fractions. The gangliosides incorporated into chlolesterol/phosphatidylcholine liposomes stoicheiometrically inhibited binding of anti-(blood-group-I and i) antibodies to a radioiodinated blood-group-Ii-active glycoprotein. The fraction with the highest blood-group-I activity, I(g) fraction, behaved like sialosyl-deca- to dodeca-glycosylceramides on t.l.c. Certain blood-group-I and most of the i-determinants were in partially or completely cryptic form and could be unmasked by sialidase treatment. Thus the I and i antigens, which are known to occur on internal structures of blood-group-ABH-active glycoproteins in secretions, also occur in the interior of the carbohydrate chains of erythrocyte gangliosides.

Rodriguez, Hector P; Crane, Paul K

2011-01-01

Objective To evaluate psychometric properties of a widely used patient experience survey. Data Sources English-language responses to the Clinician & Group Consumer Assessment of Healthcare Providers and Systems (CG-CAHPS®) survey (n = 12,244) from a 2008 quality improvement initiative involving eight southern California medical groups. Methods We used an iterative hybrid ordinal logistic regression/item response theory differential item functioning (DIF) algorithm to identify items with DIF related to patient sociodemographic characteristics, duration of the physician–patient relationship, number of physician visits, and self-rated physical and mental health. We accounted for all sources of DIF and determined its cumulative impact. Principal Findings The upper end of the CG-CAHPS® performance range is measured with low precision. With sensitive settings, some items were found to have DIF. However, overall DIF impact was negligible, as 0.14 percent of participants had salient DIF impact. Latinos who spoke predominantly English at home had the highest prevalence of salient DIF impact at 0.26 percent. Conclusions The CG-CAHPS® functions similarly across commercially insured respondents from diverse backgrounds. Consequently, previously documented racial and ethnic group differences likely reflect true differences rather than measurement bias. The impact of low precision at the upper end of the scale should be clarified. PMID:22092021

It is well recognised that the adoption and longer term adherence to physical activity by adults to reduce the risk of chronic disease is a challenge. Interventions, such as group and home based physical activity programs, have been widely reported upon. However few studies have directly compared these interventions over the longer term to determine their adherence and effectiveness. Participant preference for home based or group interventions is important. Some evidence suggests that home based physical activity programs are preferred by middle aged adults and provide better long term physical activity adherence. Physiotherapists may also be useful in increasing physical activity adherence, with limited research on their impact. 'Physical Activity at Home' is a 2 year pragmatic randomised control trial, with a non-randomised comparison to group exercise. Middle-aged adults not interested in, or unable to attend, a group exercise program will be targeted. Sedentary community dwelling 50-65 year olds with no serious medical conditions or functional impairments will be recruited via two mail outs using the Australian federal electoral roll. The first mail out will invite participants to a 6 month community group exercise program. The second mail out will be sent to those not interested in the group exercise program inviting them to take part in a home based intervention. Eligible home based participants will be randomised into a 6 month physiotherapy-led home based physical activity program or usual care. Outcome measures will be taken at baseline, 6, 12, 18 and 24 months. The primary outcome is physical activity adherence via exercise diaries. Secondary outcomes include the Active Australia Survey, accelerometry, aerobic capacity (step test), quality of life (SF-12v2), blood pressure, waist circumference, waist-to-hip ratio and body mass index. Costs will be recorded prospectively and qualitative data will be collected. The planned 18 month follow-up post

We examined smoking cessation rate by education and determined how much of the difference can be attributed to the rate of quit attempts and how much to the success of these attempts. We analyzed data from the National Health Interview Survey (NHIS, 1991-2010) and the Tobacco Use Supplement to the Current Population Survey (TUS-CPS, 1992-2011). Smokers (≥ 25 years) were divided into lower- and higher-education groups (≤ 12 years and >12 years). A significant difference in cessation rate between the lower- and the higher-education groups persisted over the last 2 decades. On average, the annual cessation rate for the former was about two thirds that of the latter (3.5% vs 5.2%; Peducation group have consistently lagged behind their higher-education counterparts in quitting. In addition to the usual concern about improving their success in quitting, tobacco control programs need to find ways to increase quit attempts in this group.

Obesity and other lifestyle-related chronic diseases impact urban West African women at high rates. Physical activity (PA) can improve these health outcomes but there is little published data on the associated psychosocial predictors in this population. We aimed to explore preliminary associations between perceptions of PA, PA behaviours, and health in a group of Ghanaian women. Non-experimental, cross-sectional case study using a mixed-methods approach. Focus groups and in-depth interviews with a convenience sample of Ghanaian women, fitness trainers and clergy comprised the qualitative phase. A self-administered survey (n=218) comprised the quantitative phase. Constant comparative method, logistic regression, component and factor analyses were used for analysis. Women viewed activities of daily living like housework as PA; rarely utilized organized fitness facilities; understood "rigorous" PA as professional male athleticism; and took interest in socialized PA. Mean age was 49.4 years. Mean body mass index was 30.3 kg/m2. The majority (75.9 %) reported exercising sometimes or often. Half (48.4%) reported a lifestyle-related chronic disease. "Weight loss," "health concerns" and "increased energy," were top motivators for PA. "Can't find the time," "work/family obligations," and "don't have a facility" were top barriers. Presence of hypertension, hypercholesterolemia and prior weight loss correlated with the slimming motivator (adjusted odds ratio 2.59, p=0.008; AOR 3.56, p=0.012; AOR 3.36, p=surveyed, PA motivators and barriers were associated with demographics, PA exposure, and health status. Further research on unique PA perceptions, behaviours and health could catalyze health promotion through culturally relevant fitness programming.

The Origin of Stellar Species: constraining stellar evolution scenarios with Local Group galaxy surveys

Our understanding of the progenitors of many stellar species, such as supernovae, massive and low-mass He-burning stars, is limited because of many poorly constrained aspects of stellar evolution theory. For my dissertation, I have focused on using Local Group galaxy surveys to constrain stellar evolution scenarios by measuring delay-time distributions (DTD). The DTD is the hypothetical occurrence rate of a stellar object per elapsed time after a brief burst of star formation. It is the measured distribution of timescales on which stars evolve, and therefore serves as a powerful observational constraint on theoretical progenitor models. The DTD can be measured from a survey of stellar objects and a set of star-formation histories of the host galaxy, and is particularly effective in the Local Group, where high-quality star-formation histories are available from resolved stellar populations. I am currently calculating a SN DTD with supernova remnants (SNRs) in order to provide the strongest constraints on the progenitors of thermonuclear and core-collapse supernovae. However, most SNRs do not have reliable age measurements and their evolution depends on the ambient environment. For this reason, I wrote a radio light curve model of an SNR population to extract the visibility times and rates of supernovae - crucial ingredients for the DTD - from an SNR survey. The model uses observational constraints on the local environments from multi-wavelength surveys, accounts for missing SNRs and employs the latest models of shock-driven particle acceleration. The final calculation of the SN DTD in the Local Group is awaiting completion of a systematic SNR catalog from deep radio-continuum images, now in preparation by a group led by Dr. Laura Chomiuk. I have also calculated DTDs for the LMC population of RR Lyrae and Cepheid variables, which serve as important distance calibrators and stellar population tracers. We find that Cepheids can have delay-times between 10 Myrs - 1 Gyr

1999-03-01

The purpose of this survey and analysis is to identify the level of demand for the HANARO utilization that will be applied to developing experimental facilities, to advertise the HANARO, and to find able staff members for user group organization. The demand survey was performed on a nationwide basis of universities, hospitals, research institute, industrial firms, and public institutions from May 7, 1998 to July 30, 1998 through the internet, electronic mail, mail or fax. This survey contains of two parts: the first part is to identify the demand for the experimental facilities of HANARO such as neutron beam, cold neutron beam, fuel and material irradiation testing, radioisotope, neutron activation analysis, boron neutron capture therapy, and neutron transmutation doping. The second part is to survey the intention of participating in the neutron beam user group, radioisotope user group, and fuel and material irradiation testing user group. 1,181 individuals have replied to the survey. The number of replies concerning the utilization of HANARO and the user groups are 3,374 and 440, respectively. The results of this demand survey will be analyzed and used to the study of a more active utilization and a more efficient management of HANARO. They will be applied to the future planning the development of the experimental facilities of HANARO. (author). 22 tabs., 30 figs

Contaminated site cleanup decisions may require estimation of dermal exposures to soil. Telephone surveys represent one means of obtaining relevant activity pattern data. The initial Soil Contact Survey (SCS-I), which primarily gathered information on the activities of adults, was conducted in 1996. Data describing adult behaviors have been previously reported. Results from a second Soil Contact Survey (SCS-II), performed in 1998-1999 and focused on children's activity patterns, are reported here. Telephone surveys were used to query a randomly selected sample of U.S. households. A randomly chosen child, under the age of 18 years, was targeted in each responding household having children. Play activities as well as bathing patterns were investigated to quantify total exposure time, defined as activity time plus delay until washing. Of 680 total survey respondents, 500 (73.5%) reported that their child played outdoors on bare dirt or mixed grass and dirt surfaces. Among these "players," the median reported play frequency was 7 days/week in warm weather and 3 days/week in cold weather. Median play duration was 3 h/day in warm weather and 1 h/day in cold weather. Hand washes were reported to occur a median of 4 times per day in both warm and cold weather months. Bath or shower median frequency was seven times per week in both warm and cold weather. Finally, based on clothing choice data gathered in SCS-I, a median of about 37% of total skin surface is estimated to be exposed during young children's warm weather outdoor play.

2010-07-01

This study sought to investigate the walking habits of older people from diverse cultural backgrounds, and to identify the factors associated with their walking. Three hundred and thirty three people over the age of 60 years were recruited from seven culturally diverse groups from the Western suburbs of Melbourne, Australia. A survey questionnaire recording physical activity, and various factors related to activity, was interviewer-administered in the participants' preferred language. Data were analysed using Kruskal-Wallis, chi(2) and Mann-Whitney tests. Forty-seven percent of the participants walked at least 150 min per week, with no significant difference in prevalence between genders or cultural groups. Some cultural differences were found in relation to reasons and locations for walking, and women were more likely than men to report walking in the shopping mall, whilst men were more likely than women to report walking in the park and along walking trails. Those who attained >150 min of walking were more likely to report health and fitness as reasons for walking, to perceive their walking environment as more pleasurable, to use walking trails, and to consider their environment safe and to facilitate social interaction. This study indicates that the continued advocating of walking as a health promoting activity should be central to future campaigns to increase physical activity in this age group. The provision of locations that are accessible, safe, aesthetically pleasing, and encourage social engagement are likely to facilitate older people's participation in walking. For maximum effectiveness, however, strategies may benefit from being tailored to meet specific gender and cultural preferences. Copyright 2009 Sports Medicine Australia. Published by Elsevier Ltd.

Therapeutic importance of physical activity during and after cancer treatment has been supported. To examine the patterns of physical activity according to the stages of breast and colorectal cancer survivor-ship in Korean, Korean National Health and Nutrition Examination Survey data from 2008 to 2011 were used. International Physical Activity Questionnaire (IPAQ) was utilized to estimate weekly time spent in vigorous- and moderate-intensity physical activity, and walking, and to calculate MET-minute/week. Depending on the survivorship, the subjects were categorized into "never diagnosed with cancer" (group 1), "0-4 yr since cancer diagnosis" (group 2), and "5 or more years since cancer diagnosis" (group 3), separately for colorectal and breast cancer. The associations between physical activity and the cancer survivorship were studied. Following results were obtained: (1) Breast cancer (n=10,167, mean age=48.55±16.27): The mean physical activity levels expressed in MET-minutes/week were 2,064.83, 1748.82, and 1998.36 in groups 1, 2, and 3, respectively. Even though cancer survivors tended to be less active compared to people without cancer, there were no statistically significant difference among the three groups. (2) Colorectal cancer (n=17,270, mean age=48.62): MET-minutes/week was 2064.30, 1084.83, and 709.04 36 in groups 1, 2, and 3, respectively. The differences were significant between group 1 and 2 (F=5.87, P=0.016) and group 1 and 3 (F=28.99, Pphysical activity, colorectal cancer survivors were less active than people without cancer in Korea.

Tripathi, Raakhi K; Sarkate, Pankaj V; Jalgaonkar, Sharmila V; Rege, Nirmala N

2015-01-01

Current teaching in pharmacology in undergraduate medical curriculum in India is primarily drug centered and stresses imparting factual knowledge rather than on pharmacotherapeutic skills. These skills would be better developed through active learning by the students. Hence modules that will encourage active learning were developed and compared with traditional methods within the Seth GS Medical College, Mumbai. After Institutional Review Board approval, 90 second year undergraduate medical students who consented were randomized into six sub-groups, each with 15 students. Pre-test was administered. The three sub-groups were taught a topic using active learning modules (active learning groups), which included problems on case scenarios, critical appraisal of prescriptions and drug identification. The remaining three sub-groups were taught the same topic in a conventional tutorial mode (tutorial learning groups). There was crossover for the second topic. Performance was assessed using post-test. Questionnaires with Likert-scaled items were used to assess feedback on teaching technique, student interaction and group dynamics. The active and tutorial learning groups differed significantly in their post-test scores (11.3 ± 1.9 and 15.9 ± 2.7, respectively, P active learning session as interactive (vs. 37/90 students in tutorial group) and enhanced their understanding vs. 56/90 in tutorial group), aroused intellectual curiosity (47/90 students of active learning group vs. 30/90 in tutorial group) and provoked self-learning (41/90 active learning group vs. 14/90 in tutorial group). Sixty-four students in the active learning group felt that questioning each other helped in understanding the topic, which was the experience of 25/90 students in tutorial group. Nevertheless, students (55/90) preferred tutorial mode of learning to help them score better in their examinations. In this study, students preferred an active learning environment, though to pass examinations, they

The Pollutant Assessments Group (PAG) at the Grand Junction Office (GJO), Colorado, of Oak Ridge National Laboratory (ORNL) is responsible for surveying designated sites in the vicinity of 24 inactive mill sites involved in the Department of Energy's (DOE) Uranium Mill Tailings Remedial Action Project (UMTRAP). The purpose of these surveys is to provide a recommendation to DOE whether to include or exclude these sites from UMTRAP based on whether the on-site residual radioactive material (if any) originated from the former mill sites, and radiation levels on-site are in excess of appropriate Environmental Protection Agency (EPA) criteria. This report describes the Quality Assurance Plan (QAP) for the PAG in conducting all activities related to UMTRAP. All quality assurance provisions given by the DOE, DOE/UMTRA and ORNL organizations are integrated into this plan. Specifically, this report identifies the policies and procedures followed in accomplishing the PAG/UMTRA QA program, identifies those organizational units involved in the implementation of these procedures, and outlines the respective responsibilities of those groups. 11 refs., 6 figs., 3 tabs

1996-01-01

The assessment of health risk due to environmental contaminants depends upon accurate estimates of the distribution of population exposures. Exposure assessment, in turn, requires information on the time people spend in micro-environments and their activities during periods of exposure. This paper describes preliminary results including study methodology and population sampled in a large Canadian survey of time-activity patterns. A 24-hour diary recall survey was performed in 2381 households (representing a 65% response rate) to describe in detail the timing, location and activity pattern of one household member (the adult or child with the next birthday). Four cities (Toronto, Vancouver, Edmonton and Saint John, NB) and their suburbs were sampled by random-digit dialling over a nine-month period in 1994/1995. Supplemental questionnaires inquiring about sociodemographic information, house and household characteristics and potential exposure to toxins in the air and water were also administered. In general, the results show that respondents spend the majority of their time indoors (88.6%) with smaller proportions of time outdoors (6.1%) and in vehicles (5.3%). Children under the age of 12 spend more time both indoors and outdoors and less time in transit than do adults. The data from this study will be used to define more accurately the exposure of Canadians to a variety of toxins in exposure assessment models and to improve upon the accuracy of risk assessment for a variety of acute and chronic health effects known or suspected to be related to environmental exposures.

The Board of Directors of Gaz de France approved the Group's consolidated accounts for 2004. In a more dynamic economic environment than in 2003, the Gaz de France Group reports enhanced results and has continued to pursue its growth in Europe. Increase in net sales driven by sustained growth in sales (+ 8.9%): In 2004, net sales rose 8.9% compared with the 2003 financial year to reach a total of euro 18,129 m. This strong increase in business activities was driven by sustained growth in sales volumes both in France and Europe. Total Group sales volumes amounted to 730 TWh (approximately 66 billion cubic metres), equal to growth of 10.3%. Natural gas sales volumes increased by approximately 10% in France, and are almost 18% higher in Europe, notably in the United Kingdom, Italy, Belgium and the Netherlands. The Group has pursued the profitable development of its activities outside France. As a result, international activities account for 29% of total sales in 2004, against 23% in 2003. The contribution made by international subsidiaries - particularly those specializing in exploration and production - grew by a very substantial 44.3% to reach a total of euro 502 m in 2004. Energy and Services Offering Branch: this core business line, which includes natural gas and oil exploration and production, energy trading and sales, and services associated with the supply of energy, boasts net sales of euro 16,498 m, equal to growth of 10.8% compared with 2003. Infrastructures Branch: this division, which groups together all activities related to the management of transmission and distribution infrastructures in both the French domestic and international markets, generated net sales of euro 6,794 m in 2004, virtually unchanged from the previous year. This situation is the result of higher sales generated by the distribution subsidiaries operating outside France (+9.2%) offset by a decline in the sales performance of the Transmission, Storage and Distribution in France

Increasing physical activity and decreasing sedentary behavior are associated with a higher quality of life and lower mortality rates for cancer survivors, a growing population group. Studies detailing the behavior of cancer survivors are limited. Therefore, we investigated physical activity and sedentary behavior of cancer survivors using data from the National Health and Nutrition Examination Survey (NHANES) 2007-2010. Participants were those who provided physical activity and sedentary behavior data. Those who were pregnant, physical activity, compared to non-cancer participants. These patterns are similar for breast and prostate cancer survivors, with prostate cancer survivors more likely to engage in physical activity for more than one hour per day (OR = 1.98, 95% CI (1.05, 3.71)). Our findings suggest that cancer survivors tend to have more physical activity, but they are also more likely to engage in sedentary behavior.

To examine associations of descriptive norms (i.e., behaviors of social group members) and exercising 'with a partner' or 'as a part of a group' on weekly leisure-time physical activity. T-tests and adjusted multivariable linear models were used to test the associations between descriptive norms and exercising with a partner or as a part of a group with self-reported leisure-time physical activity using the cross-sectional, population-based New York City Physical Activity and Transit (PAT) Survey 2010-2011 (n=3806). Overall, 70.6% of adult New Yorkers reported having physically active friends. Having active friends was associated with increased leisure-time physical activity; however, the effect varied by sex. Compared to those who did not have active friends, males with active friends reported two times more activity (56 min/week) and women reported two and a half times more activity (35 min/week) (both p-valuesPhysically active males and females who usually engaged in leisure-time activities as a part of a group reported 1.4 times more activity than those who exercised alone (both p-valuesexercise were associated with leisure-time physical activity among adults.

Chauvin, Claire; Beloeil, Pierre-Alexandre; Orand, Jean-Pierre; Sanders, Pascal; Madec, François

2002-09-30

There is world-wide concern that antimicrobial use in food-producing animals might contribute to antimicrobial resistance both in animals and in humans. The relationship between antimicrobial use and resistance is likely to be related to frequency of prescription of the compound, dose and duration of treatment. Routine collection of that information is not possible today in France. A postal survey of French pig veterinarians therefore was carried out in October 2000. The questionnaire focused on the last antibiotic group-level prescription made; data were collected on the type of animals, presumptive clinical diagnosis and drug prescription. The list frame was defined using a veterinary yearbook. All practitioners with mention of pig in the treated species or with employment in intensive animal production were sent the questionnaire. Out of the 431 selected practitioners, 303 responded to the self-administered questionnaire (overall return proportion 70%). 159 prescriptions were received and analysed (response proportion 37%). Their repartitions according to indications and active compounds were summarised. Mean prescribed daily doses and mean treatment length were calculated for four antibiotics: amoxicillin, colistin, oxytetracycline, tylosin. Prescribed daily dose were in the range of dosages used and recommended in Europe. High variations were encountered in treatment length: from 3 to 21 days.

A Group Recommender System for Tourist Activities

Science.gov (United States)

Garcia, Inma; Sebastia, Laura; Onaindia, Eva; Guzman, Cesar

This paper introduces a method for giving recommendations of tourist activities to a group of users. This method makes recommendations based on the group tastes, their demographic classification and the places visited by the users in former trips. The group recommendation is computed from individual personal recommendations through the use of techniques such as aggregation, intersection or incremental intersection. This method is implemented as an extension of the e-Tourism tool, which is a user-adapted tourism and leisure application, whose main component is the Generalist Recommender System Kernel (GRSK), a domain-independent taxonomy-driven search engine that manages the group recommendation.

Full Text Available Thanks to its use independently of time and place during the process of software development and by making it easier to access to information with mobile technologies, cloud based environments attracted the attention of education world and this technology started to be used in various activities. In this study, for programming education, the effects of extracurricular group assignments in cloud based environments on learners were evaluated in terms of group work satisfaction, ease of use and user satisfaction. Within the scope of computer programming education lasting eight weeks, a total of 100 students participated in the study including 34 men and 66 women. Participants were divided into groups of at least three people considering the advantages of cooperative learning in programming education. In this study carried out in both conventional and cloud based environments, between groups factorial design was used as research design. The data collected by questionnaires of opinions of group work were examined with quantitative analysis method. According to the study results extracurricular learning activities as group activity created satisfaction. However, perceptions of easy use of the environment and user satisfaction were partly positive. Despite the similar understandings; male participants were easier to perceive use of cloud computing based environments. Some variables such as class level, satisfaction, computer and internet usage time do not have any effect on satisfaction and perceptions of ease of use. Evening class students stated that they found it easy to use cloud based learning environments and became more satisfied with using these environments besides being happier with group work than daytime students.

Estimation of population exposure is a main component of human health risk assessment for environmental contaminants. Population-level exposure assessments require time-activity pattern distributions in relation to microenvironments where people spend their time. Societal trends may have influenced time-activity patterns since previous Canadian data were collected 15 years ago.

The European Gaucher Alliance (EGA) was established in 1994 and constituted in 2008 as an umbrella group supporting patient organisations for Gaucher disease. Every two years, the EGA conducts a questionnaire survey of member associations to help develop its priorities and annual work programme. Results of the latest survey are presented. Between June 2012 and April 2013, the 36 members and associate members of the EGA were asked to complete a questionnaire detailing membership numbers, disease specific treatments used by patients, means of access to treatment, availability of treatment centres and home infusions, sources of support for patients with Gaucher disease, patient organisations' activities, collaborations, funding sources and any issues of concern. Questionnaires completed in 2012 were revised in January 2013 and responses analysed between July and September 2013. Thirty three members returned data on one or more questions. Findings identified inequalities in access to treatment both within and between members' countries. Three of 27 countries, for which data were available, relied totally on humanitarian aid for treatment and 6% of untreated patients in 20 countries were untreated because of funding issues, a situation many feared would worsen with deteriorating economic climates. Access to treatment and reimbursement represented 45% of members' concerns, while 35% related to access to specialist treatment centres, home infusions and doctors with expertise in Gaucher disease. Member associations' main activities centred on patient support (59% of responses) and raising awareness of Gaucher disease and patients' needs amongst the medical community, government and healthcare decision makers and the general public (34% of responses). Twenty one (78% of respondents) indicated they were the only source of help for Gaucher disease patients in their country. For many, activities were constrained by funds; two members had no external funding source. Activities

Clark, Tiana Y; Clark, Robert A

2015-11-01

To measure the difference in Convergence Insufficiency Symptom Survey scores for reading vs favorite near visual activities. Comparative validity analysis of diagnostic tools. At a single clinical private practice, 100 children aged 9-18 with normal binocular vision were recruited to receive either the original survey emphasizing reading or a modified survey replacing "reading" with their favorite near activity. Average survey scores and subscores for questions emphasizing fatigue, discomfort, impaired vision, and cognitive performance were compared using t tests, while responses to individual questions were compared using Mann-Whitney U tests. The average reading survey score was significantly greater than the favorite near activity survey score (14.1 ± 11.5 vs 6.7 ± 5.8, P = .0001). The largest difference resulted from questions emphasizing cognitive performance (subscore 5.8 ± 4.3 vs 2.0 ± 2.1, P = .0000002), although significant differences were also found for fatigue (5.4 ± 3.8 vs 3.0 ± 2.7, P = .0003), discomfort (3.9 ± 4.6 vs 1.8 ± 2.2, P = .004), and impaired vision (3.2 ± 3.9 vs 1.8 ± 2.2, P = .02). Significant differences were found for 7 survey questions, with higher symptom scores for the reading survey in every case. Using survey scores ≥16 to diagnose convergence insufficiency, significantly more children taking the reading survey would have been diagnosed with convergence insufficiency than children taking the favorite near activity survey (19 of 50 [38%] vs 5 of 50 [10%], P = .001). By emphasizing reading, the Convergence Insufficiency Symptom Survey score significantly overestimates near visual symptoms in children with normal binocular vision compared with symptoms caused by preferred near activities that require similar amplitudes of accommodation and convergence.

Activity report of the Neutrino Research Group. Year 2006

International Nuclear Information System (INIS)

2007-01-01

For the last two decades, neutrino physics has been producing major discoveries including neutrino oscillations. These results gave clear confirmation that active neutrinos oscillate and therefore have mass with three different mass states. This is a very important result showing that the Minimal Standard Model is incomplete and requires an extension which is not yet known. The neutrino research field is very broad and active, at the frontier of today's particle physics. The Neutrino Research Group (GDR) was created in January 2005 with the aim of gathering CEA and CNRS research teams working on Neutrino Physics on experimental or theoretical level. This document is the 2006 activity report of the research group, two years after its creation. It presents the results of the 5 working groups: 1 - Determination of neutrino parameters; 2 - Physics beyond the standard model; 3 - Neutrinos in the universe; 4 - Accelerators, detection means, R and D and valorisation; 5 - Common tools to all working groups. The proposed neutrino physics road-map and the actual and future short-, medium- and long-term projects are presented in appendixes. The Neutrino research group organization, the Memphys specific mission group, the research group participating laboratories and teams, as well as the Memphys project are presented too

2016-01-01

This book presents articles at the interface of two active areas of research: classical topology and the relatively new field of geometric group theory. It includes two long survey articles, one on proofs of the Farrell–Jones conjectures, and the other on ends of spaces and groups. In 2010–2011, Ohio State University (OSU) hosted a special year in topology and geometric group theory. Over the course of the year, there were seminars, workshops, short weekend conferences, and a major conference out of which this book resulted. Four other research articles complement these surveys, making this book ideal for graduate students and established mathematicians interested in entering this area of research.

Correlates of sedentary time in different age groups: results from a large cross sectional Dutch survey.

Evidence shows that prolonged sitting is associated with an increased risk of mortality, independent of physical activity (PA). The aim of the study was to identify correlates of sedentary time (ST) in different age groups and day types (i.e. school-/work day versus non-school-/non-work day). The study sample consisted of 1895 Dutch children (4-11 years), 1131 adolescents (12-17 years), 8003 adults (18-64 years) and 1569 elderly (65 years and older) who enrolled in the Dutch continuous national survey 'Injuries and Physical Activity in the Netherlands' between 2006 and 2011. Respondents estimated the number of sitting hours during a regular school-/workday and a regular non-school/non-work day. Multiple linear regression analyses on cross-sectional data were used to identify correlates of ST. Significant positive associations with ST were observed for: higher age (4-to-17-year-olds and elderly), male gender (adults), overweight (children), higher education (adults ≥ 30 years), urban environment (adults), chronic disease (adults ≥ 30 years), sedentary work (adults), not meeting the moderate to vigorous PA (MVPA) guideline (children and adults ≥ 30 years) and not meeting the vigorous PA (VPA) guideline (4-to-17-year-olds). Correlates of ST that significantly differed between day types were working hours and meeting the VPA guideline. More working hours were associated with more ST on school-/work days. In children and adolescents, meeting the VPA guideline was associated with less ST on non-school/non-working days only. This study provides new insights in the correlates of ST in different age groups and thus possibilities for interventions in these groups. Correlates of ST appear to differ between age groups and to a lesser degree between day types. This implies that interventions to reduce ST should be age specific. Longitudinal studies are needed to draw conclusions on causality of the relationship between identified correlates and ST.

Biochemical survey for children of A-bomb survivors

International Nuclear Information System (INIS)

Sato, Chiyoko

1992-01-01

The Radiation Effects Research Foundation has conducted biochemical survey in children of A-bomb survivors, with the purpose of elucidating whether or not the rate of genetic mutation in genital cells is increased. This paper describes the previous surveys done at protein levels. Two kinds of indicators have been used: (1) 'rare mutation type' reflecting base substitution mutation, base deletion, and insertion; (2) 'mutation type' reflecting the decrease of red cell enzyme activity. According to the DS86 dosimetry system, the children population of A-bomb survivors were examined by dividing into the exposed group (n=11,364) of their parents exposed to 0.01 Sv or more and the control group (n=12,297) of those exposed to less than 0.01 Sv. 'Rare mutation type' was detected using electrophoresis in a total of 1,233 children in both groups. Of these children, 2 in the exposed group and 4 in the control group had a new 'mutation', i.e., mutation that was considered to have occurred in genital cells of their parents. Survey for genetic foci has revealed mutation in 2 children in the exposed group and 4 children in the control group, with the rate of mutation being 0.37 x 10 -5 /genetic foci/generation and 0.68 x 10 -5 /genetic foci/generation, respectively. Mutation type reflecting the decrease in red cell enzyme activity was seen in 26 in the exposed group and 21 in the control group. A total of 41 children were found to have been inherited from their parents. In the survey for genetic foci, only one had mutation in the exposed group, with the rate of mutation being 1.7 x 10 -5 /genetic foci/generation. These findings have revealed no evidence of significant difference in the rate of mutation between the exposed and control groups. Finally, the future genetic surveys at molecular levels are briefly discussed. (N.K.)

Multiple linear regression was performed to estimate association of social change variables and lifestyle on quality of life score (QoL; measured by CASP-16 Brazil, score can range from 0, which represents no QoL to 48, total satisfaction in all domains of CASP. The average QoL score in the sample was 37.6 (95%CI: 37.2; 38.1. The social relations that were associated with positive QoL score were to start to work, to continue to use the Internet, to start participating in religious or lifestyle groups, to remain and to become physically active, and for those who were physically active, but became inactive in the second wave. To remain living with family had a negative effect on QoL score for the elderly. Some changes in social relations had a positive effect on QoL, and results reaffirmed the importance of physical activity to healthy aging, since to pursue it in some of the waves was better than to remain inactive.

A domain-specific physical activity questionnaire (EHIS-PAQ) was developed in the framework of the second wave of the European Health Interview Survey (EHIS). This article presents the EHIS-PAQ and describes its development and evaluation processes. Research institutes from Belgium, Estonia and Germany participated in the Improvement of the EHIS (ImpEHIS) Grant project issued by Eurostat. The instrument development process comprised a non-systematic literature review and a systematic HIS/HES database search for physical activity survey questions. The developed EHIS-PAQ proposal was reviewed by survey experts. Cognitive testing of the EHIS-PAQ was conducted in Estonia and Germany. The EHIS-PAQ was further tested in a pilot survey in Belgium, Estonia and Germany in different modes of data collection, face-to-face paper and pencil interview (PAPI) and computer assisted telephone interview (CATI). The EHIS-PAQ is a rather pragmatic tool aiming to evaluate how far the population is physically active in specific public health relevant settings. It assesses work-related, transport-related and leisure-time physical activity in a typical week. Cognitive testing revealed that the EHIS-PAQ worked as intended. The pilot testing showed the feasibility of using the EHIS-PAQ in an international health interview survey setting in Europe. It will be implemented in all 28 European Union Member States via European Union implementing regulation in the period between 2013 and 2015. This will be a first opportunity to get comparable data on domain-specific physical activity in all 28 EU MS and to publish indicators at the EU level. The EHIS-PAQ is a short, domain-specific PA questionnaire based on PA questions which have been used in large-scale health interview surveys before. It was designed by considering the respondents' perspective in answering PA questions.

Full Text Available The study investigated perceived ease of use and usefulness of Google Hangouts as an instructional/learning tool. Forty-two teacher education students at U.S and Japanese universities participated in an online cross-cultural activity using Google Hangouts and discussed cultural differences between the two countries and their teaching philosophies. After the activity, students responded to a survey to evaluate the ease of use and usefulness of Google Hangouts. Qualitative data were also collected through the survey to examine their overall learning experience. The results indicated that Google Hangouts is a useful instructional tool, but not easy to use. Although technical problems occurred during the conference, the activity provided valuable experiences for both U.S. and Japanese students. The study provides suggestions for how Google Hangouts can be integrated into online classrooms based on the findings.

Alcohol use is among the most important risk factors for burden of disease globally. An estimated quarter of the total alcohol consumed globally is unrecorded. However, due partly to the challenges associated with its assessment, evidence concerning the magnitude of unrecorded alcohol use is sparse. This study estimated country-specific proportions of unrecorded alcohol used in 2015. A statistical model was developed for data prediction using data on the country-specific proportion of unrecorded alcohol use from nominal group expert assessments and secondary, nationally representative survey data and country-level covariates. Estimates were calculated for the country level, for four income groups and globally. A total of 129 participants from 49 countries were included in the nominal group expert assessments. The survey data comprised 66 538 participants from 16 countries. Experts completed a standardized questionnaire assessing the country-specific proportion of unrecorded alcohol. In the national surveys, the number of standard drinks of total and unrecorded alcohol use was assessed for the past 7 days. Based on predictions for 167 countries, a population-weighted average of 27.9% [95% confidence interval (CI) = 10.4-44.9%] of the total alcohol consumed in 2015 was unrecorded. The proportion of unrecorded alcohol was lower in high (9.4%, 95% CI = 2.4-16.4%) and upper middle-income countries (18.3%, 95% CI = 9.0-27.6%) and higher in low (43.1%, 95% CI = 26.5-59.7%) and lower middle-income countries (54.4%, 95% CI = 38.1-70.8%). This corresponded to 0.9 (high-income), 1.2 (upper middle-income), 3.2 (lower middle-income) and 1.8 (low-income) litres of unrecorded alcohol per capita. A new method for modelling the country-level proportion of unrecorded alcohol use globally showed strong variation among geographical regions and income groups. Lower-income countries were associated with a higher proportion of unrecorded alcohol than higher-income countries

The neutrino research field is very broad and active, at the frontier of today's particle physics. The Neutrino Research Group (GDR) was created in January 2005 with the aim of gathering CEA and CNRS research teams working on Neutrino Physics on experimental or theoretical level. This document is the 2010 activity report of the research group, six years after its creation. It presents the results of the 5 working groups: 1 - Determination of neutrino parameters; 2 - Physics beyond the standard model; 3 - Neutrinos in the universe; 4 - Accelerators, detection means, R and D and valorisation; 5 - Common tools to all working groups. The proposed neutrino physics road-map and the actual and future short-, medium- and long-term projects are presented in appendixes

Botti, Lucia; Ferrari, Emilio; Mora, Cristina

2017-04-01

Work in confined spaces poses a significant risk to workers and rescuers involved in the emergency response when an accident occurs. Despite several standards and regulations define the safety requirements for such activities, injuries, and fatalities still occur. Furthermore, the on-site inspections after accidents often reveal that both employers and employees fail to implement safe entry procedures. Removing the risk is possible by avoiding the worker entry, but many activities require the presence of the operator inside the confined space to perform manual tasks. The following study investigates the available technologies for hazardous confined space work activities, e.g., cleaning, inspecting, and maintenance tasks. The aim is to provide a systematic review of the automated solutions for high-risk activities in confined spaces, considering the non-man entry as the most effective confined space safety strategy. Second, this survey aims to provide suggestions for future research addressing the design of new technologies. The survey consists of about 60 papers concerning innovative technologies for confined space work activities. The document review shows that several solutions have been developed and automation can replace the workers for a limited number of hazardous tasks. Several activities still require the manual intervention due to the complex characteristics of confined spaces, e.g., to remove the remains of the automatic cleaning process from the bottom of a tank. The results show that available technologies require more flexibility to adapt to such occupational environments and further research is needed.

Full Text Available Since WeChat has been launched in 2011, as of the first quarter of 2015, the active users have reached 549 million per month1. WeChat has become the largest mobile instant messaging software among the user groups in Asia. Therefore, WeChat is no longer “micro”, and grabs the attention of more youth groups by virtue of the “micro” advantages in the Internet era in a way of low-priced new media. Through sorting 192 effective questionnaires recovered, this paper summarizes some transmitting tendency and suggestions of “micro” innovation diffusion from the research view of the concept of innovation diffusion theory, and development stage of WeChat in the youth group, based on the survey data and by the use of the statistics of informatics, qualitative and quantitative analysis method, so as to provide a certain theoretical basis for the future research of WeChat.

Factors Associated With Volunteering Among Racial/Ethnic Groups: Findings From the California Health Interview Survey.

Science.gov (United States)

Johnson, Kimberly J; Lee, S Hannah

2017-06-01

The present study investigated how volunteering was influenced by individual resources and social capital among four racial/ethnic groups of adults aged 50 and older. The data came from the California Health Interview Survey, a statewide sample that includes non-Hispanic Whites ( n = 18,927), non-Hispanic Asians ( n = 2,428), non-Hispanic Blacks ( n = 1,265), and Hispanics ( n = 3,799). Logistic regression models of volunteering were estimated to explore the effects of human and social capital within and across the racial/ethnic groups. Compared to Whites, racial/ethnic minority adults volunteered less. Although education was a significant predictor of volunteering across all groups, the findings indicated group-specific factors related to human and social capital. Results showed similarities and differences associated with volunteer participation among diverse racial/ethnic groups. The findings underscore the importance of understanding ways of creating inclusive opportunities for civic engagement among an increasingly diverse population.

2015-06-01

The Undergraduate Medical Education (UME) programme at the University of Calgary is a three-year programme with a strong emphasis on small group learning. The purpose of our study was to determine whether librarian led small group information literacy instruction, closely integrated with course content and faculty participation, but without a hands on component, was an effective means to convey EBM literacy skills. Five 15-minute EBM information literacy sessions were delivered by three librarians to 12 practicing physician led small groups of 15 students. Students were asked to complete an online survey before and after the sessions. Data analysis was performed through simple descriptive statistics. A total of 144 of 160 students responded to the pre-survey, and 112 students answered the post-survey. Instruction in a small group environment without a mandatory hands on component had a positive impact on student's evidence-based information literacy skills. Students were more likely to consult a librarian and had increased confidence in their abilities to search and find relevant information. Our study demonstrates that student engagement and faculty involvement are effective tools for delivering information literacy skills when working with students in a small group setting outside of a computer classroom. © 2015 Health Libraries Group.

Ovalbumin with Glycated Carboxyl Groups Shows Membrane-Damaging Activity

Directory of Open Access Journals (Sweden)

Ching-Chia Tang

2017-02-01

Full Text Available The aim of the present study was to investigate whether glycated ovalbumin (OVA showed novel activity at the lipid-water interface. Mannosylated OVA (Man-OVA was prepared by modification of the carboxyl groups with p-aminophenyl α-dextro (d-mannopyranoside. An increase in the number of modified carboxyl groups increased the membrane-damaging activity of Man-OVA on cell membrane-mimicking vesicles, whereas OVA did not induce membrane permeability in the tested phospholipid vesicles. The glycation of carboxyl groups caused a notable change in the gross conformation of OVA. Moreover, owing to their spatial positions, the Trp residues in Man-OVA were more exposed, unlike those in OVA. Fluorescence quenching studies suggested that the Trp residues in Man-OVA were located on the interface binds with the lipid vesicles, and their microenvironment was abundant in positively charged residues. Although OVA and Man-OVA showed a similar binding affinity for lipid vesicles, the lipid-interacting feature of Man-OVA was distinct from that of OVA. Chemical modification studies revealed that Lys and Arg residues, but not Trp residues, played a crucial role in the membrane-damaging activity of Man-OVA. Taken together, our data suggest that glycation of carboxyl groups causes changes in the structural properties and membrane-interacting features of OVA, generating OVA with membrane-perturbing activities at the lipid-water interface.

Ultra-compact high velocity clouds in the ALFALFA HI survey: Candidate Local Group galaxies?

Science.gov (United States)

Adams, Elizabeth Ann Kovenz

The increased sensitivity and spatial resolution of the ALFALFA HI survey has resulted in the detection of ultra-compact high velocity clouds (UCHVCs). These objects are good candidates to represent low mass gas-rich galaxies in the Local Group and Local Volume with stellar populations that are too faint to be detected in extant optical surveys. This idea is referred to as the "minihalo hypothesis". We identify the UCHVCs within the ALFALFA dataset via the use of a 3D matched filtering signal identification algorithm. UCHVCs are selected based on a compact size ( 120 km s-1) and isolation. Within the 40% complete ALFALFA survey (alpha.40), 59 UCHVCs are identified; 19 are in a most-isolated subset and are the best galaxy candidates. Due to the presence of large HVC complexes in the fall sky, most notably the Magellanic Stream, the association of UCHVCs with existing structure cannot be ruled out. In the spring sky, the spatial and kinematic distribution of the UCHVCs is consistent with simulations of dark matter halos within the Local Group. In addition, the HI properties of the UCHVCs (if placed at 1 Mpc) are consistent with both theoretical and observational predictions for low mass gas-rich galaxies. Importantly, the HI properties of the UCHVCs are consistent with those of two recently discovered low mass gas-rich galaxies in the Local Group and Local Volume, Leo T and Leo P. Detailed follow-up observations are key for addressing the minihalo hypothesis. High resolution HI observations can constrain the environment of a UCHVC and offer evidence for a hosting dark matter halo through evidence of rotation support and comparison to theoretical models. Observations of one UCHVC at high resolution (15'') reveal the presence of a clumpy HI distribution, similar to both low mass galaxies and circumgalactic compact HVCs. An extended envelope containing ˜50% of the HI flux is resolved out by the array configuration; observations at lower spatial resolution can recover

Physical activity is an important determinant of health and fitness. This study provides contemporary estimates of the physical activity levels of Canadians aged 6 to 19 years. Data are from the 2007 to 2009 Canadian Health Measures Survey. The physical activity of a nationally representative sample was measured using accelerometers. Data are presented as time spent in sedentary, light, moderate and vigorous intensity movement, and in steps accumulated per day. An estimated 9% of boys and 4% of girls accumulate 60 minutes of moderate-to-vigorous physical activity on at least 6 days a week. Regardless of age group, boys are more active than girls. Canadian children and youth spend 8.6 hours per day-62% of their waking hours-in sedentary pursuits. Daily step counts average 12,100 for boys and 10,300 for girls. Based on objective and robust measures, physical activity levels of Canadian children and youth are low.

2004-07-01

The purpose of this study was to determine whether a theory-based framework could be used to deductively identify and understand the characteristics of motivational leaders of physical activity groups for older adults. Participants were 23 older adults (mean age = 78.5 +/- 8.0 years, 65% women). An interview-guide approach was employed to elicit older adults' thoughts on important characteristics of physical activity group leaders. The data suggested that effective leaders are those whom the participants feel are properly qualified, are able to develop a personal bond with participants, and can use their knowledge and the group to demonstrate collective accomplishments. It was concluded that the findings could be used to extend the leadership activities beyond the traditional technical performance and individual feedback to include activities of social integration. Furthermore, the conceptual framework identified can serve as a valuable tool in guiding future researchers in their examination of leadership in physical activity groups for older adults.

The 1982 salary survey of the Medical Library Group of Southern California and Arizona (MLGSCA) indicates that 211 health sciences librarians in Southern California and Arizona earned a mean annual salary of $20,910 for 1982. Data analysis shows a positive correlation between salary and educational level. Other factors found to affect salary were job history, number of positions held, MLA certification, and professional responsibility. Age, gender, and MLA certification did not have a consistent positive correlation with salary. Results indicate that the salaries of hospital librarians are, on the average, roughly comparable to those of academic librarians in Southern California and Arizona. PMID:6743878

Full Text Available Objective: To assess the quality of life of postmenopausal women who participate in different activities groups for elderly. Methods: We selected 59 women, divided as follows: hydrotherapy group (n = 15, physical activity and bingo group (n = 15, and a control group(n = 29. Data collection was done through a questionnaire evaluating the Quality of Life(WHOQOL-Bref, the Blatt and Kupperman Menopausal Index and Geriatric Depression Scale (GDS. The assessments were conducted in two stages with an interval of two monthsbetween each one. Results: There was an improvement in quality of life of women participants in activities groups with respect to the control group, and in all domains of quality of life questionnaire, the control group had lower values. Significant differences occurred in the environment domain, in comparing the hydrotherapy group and physical activity/bingo groups, of which the latter showed better responses. Conclusion: The activities groups were positive for improving quality of life of postmenopausal women, emphasizing the importance of encouraging the practice of not only physical activities, but also those that stimulate the social and psychological profile of these women.

Aerial radiological survey of the Savannah River Plant and surrounding area, Aiken, South Carolina. Date of survey: June 1979

Boyns, P.K.; Smith, D.B.

1982-07-01

An aerial radiological survey of the Savannah River Plant (SRP) was conducted during June 1979 by EG and G Energy Measurements Group for the United States Department of Energy (DOE). The survey consisted of an airborne measurement of both natural and man-made gamma radiation from the terrain surface in and around the plant site. These measurements allowed a determination of the surface terrestrial spatial distribution of isotopic concentrations and equivalent gamma ray exposure rates from 60 Co and 137 Cs contaminants. The results are reported as exposure rate isopleths for the two isotopes and are superimposed on 1:48,000 scale maps of the area. Gamma ray energy spectra are also presented for the net man-made radioelements. This was the second survey of the entire Savannah River Plant site. The first survey was conducted in June 1974. A comparison of the surveys indicates a decrease in the exposure rates due to man-made isotopes. All areas of man-made activity were in the same location as indicated by the results of the first survey. It appears that no detectable new man-made activity has been released in the survey area since the 1974 survey

Group-based education for patients with type 2 diabetes: a survey of Australian dietitians.

2017-09-01

Group-based education has the potential to substantially improve the outcomes of individuals with type 2 diabetes mellitus (T2DM) and reduce the enormous burden that chronic diseases place on healthcare systems worldwide. Despite this proven effectiveness, the utilisation of group services for the management of T2DM by Australian dietitians is surprisingly low. This study surveyed a sample of 263 Australian dietitians to explore the utilisation of group-based education for T2DM, as well as dietitians' preferences for practice and training. The results of this study indicate that Australian dietitians are currently under-utilising group-based education programs for the management of T2DM, with the primary reasons identified as a lack of training provided to dietitians in the area, limited access to facilities suitable for conducting group education, the perceived poor cost-effectiveness of these programs, and the lack of evidence-based practice guidelines for the group-based management of persons with T2DM. Additionally, the majority of preferences for further training were for either face-to-face or web-based formal training conducted over 3-6h. Clear, evidence-based practice guidelines and training resources for group education for the management of T2DM are needed in order to encourage better utilisation of group-based education by Australian dietitians.

Many countries conduct regular national time use surveys, some of which date back as far as the 1960s. Time use surveys potentially provide more detailed and accurate national estimates of the prevalence of sedentary and physical activity behavior than more traditional self-report surveillance systems. In this study, the authors determined the reliability and validity of time use surveys for assessing sedentary and physical activity behavior. In 2006 and 2007, participants (n = 134) were recruited from work sites in the Australian state of New South Wales. Participants completed a 2-day time use diary twice, 7 days apart, and wore an accelerometer. The 2 diaries were compared for test-retest reliability, and comparison with the accelerometer determined concurrent validity. Participants with similar activity patterns during the 2 diary periods showed reliability intraclass correlations of 0.74 and 0.73 for nonoccupational sedentary behavior and moderate/vigorous physical activity, respectively. Comparison of the diary with the accelerometer showed Spearman correlations of 0.57-0.59 and 0.45-0.69 for nonoccupational sedentary behavior and moderate/vigorous physical activity, respectively. Time use surveys appear to be more valid for population surveillance of nonoccupational sedentary behavior and health-enhancing physical activity than more traditional surveillance systems. National time use surveys could be used to retrospectively study nonoccupational sedentary and physical activity behavior over the past 5 decades.

To compare the effects of 1) active group music therapy and 2) receptive group music therapy to group counseling in treatment of major depressive disorder (MDD). On top of standard care, 14 MDD outpatients were randomly assigned to receive 1) active group music therapy (n=5), 2) receptive group music therapy (n=5), or 3) group counseling (n=4). There were 12 one-hour weekly group sessions in each arm. Participants were assessed at baseline, 1 month (after 4 sessions), 3 months (end of interventions), and 6 months. Primary outcomes were depressive scores measured by Montgomery-Åsberg Depression Rating Scale (MADRS) Thai version. Secondary outcomes were self-rated depression score and quality of life. At 1 month, 3 months, and 6 months, both therapy groups showed statistically non-significant reduction in MADRS Thai scores when compared with the control group (group counseling). The reduction was slightly greater in the active group than the receptive group. Although there were trend toward better outcomes on self-report depression and quality of life, the differences were not statistically significant. Group music therapy, either active or receptive, is an interesting adjunctive treatment option for outpatients with MDD. The receptive group may reach peak therapeutic effect faster, but the active group may have higher peak effect. Group music therapy deserves further comprehensive studies.

2017-06-01

Full Text Available AIM: To determine which IIRC scheme was used by retinoblastoma centers worldwide and the percentage of D eyes treated primarily with enucleation versus globe salvaging therapies as well as to correlate trends in treatment choice to IIRC version used and geographic region. METHODS: An anonymized electronic survey was offered to 115 physicians at 39 retinoblastoma centers worldwide asking about IIRC classification schemes and treatment patterns used between 2008 and 2012. Participants were asked to record which version of the IIRC was used for classification, how many group D eyes were diagnosed, and how many eyes were treated with enucleation versus globe salvaging therapies. Averages of eyes per treatment modality were calculated and stratified by both IIRC version and geographic region. Statistical significance was determined by Chi-square, ANOVA and Kruskal-Wallis tests using Prism. RESULTS: The survey was completed by 29% of physicians invited to participate. Totally 1807 D eyes were diagnosed. Regarding IIRC system, 27% of centers used the Children’s Hospital of Los Angeles (CHLA version, 33% used the Children’s Oncology Group (COG version, 23% used the Philadelphia version, and 17% were unsure. The rate for primary enucleation varied between 0 and 100% and the mean was 29%. By IIRC version, primary enucleation rates were: Philadelphia, 8%; COG, 34%; and CHLA, 37%. By geographic region, primary enucleation rates were: Latin America, 57%; Asia, 40%; Europe, 36%; Africa, 10%, US, 8%; and Middle East, 8%. However, systemic chemoreduction was used more often than enucleation in all regions except Latin America with a mean of 57% per center (P<0.0001. CONCLUSION: Worldwide there is no consensus on which IIRC version is used, systemic chemoreduction was the most frequently used initial treatment during the study period followed by enucleation and primary treatment modality, especially enucleation, varied greatly with regards to IIRC version

We examined burden and factors associated with norovirus (NoV) acute gastroenteritis (AGE) among children in rural Guatemala. Children age 6 weeks to 17 years were enrolled into three AGE surveillance groups, using two-stage cluster sampling: a prospective participatory syndromic surveillance (PSS) cohort and two cross-sectional rapid active sampling (RAS) surveys, conducted from April 2015 to February 2016. Epidemiologic and NoV testing data were used to identify factors associated with NoV infection, AGE, and NoV+ AGE. The three cross-sectional surveys (PSS enrollment visit, RAS Survey 1, and RAS Survey 2) enrolled 1,239 children, who reported 134 (11%) AGE cases, with 20% of AGE and 11% of non-AGE samples positive for NoV. Adjusted analyses identified several modifiable factors associated with AGE and NoV infection. The cross-sectional RAS surveys were practical and cost-effective in identifying population-level risk factors for AGE and NoV, supporting their use as a tool to direct limited public health resources toward high-risk populations.

The article reports on the experiences of group activities within an area of Yorkshire that helped young people with special needs to express their views and opinions. Significant issues were raised by the ethics of undertaking work with young people and these are reviewed. The young people involved in the research reported that their participation in the groups developed their self-confidence and advocacy skills. This led them to be more confident in expressing their needs at school and in the community. To establish wider generalizability for the study findings, the Yorkshire group activities were compared with another similar group in London where further data were collected from the young people involved. In facilitating group activities, willing staff were an important addition to the group because their presence provided and encouraged positive reactions to the distinctive achievements of the young people themselves. In both groups, members were committed to participation in project-based activities that raised their self-esteem and helped establish a sense of their own identity and purpose.

Since the late 1800's, when the U.S. Geological Survey first established a presence in Pennsylvania, the focus of our work has changed from general hydrologic and geologic appraisals to issue-oriented investigations; from predominantly data collection to a balanced program of data collection, interpretation, and research; and from traditional, hand-drawn mapping to digitally produced coverages with specialized themes. Yet our basic mission has not changed. It is as relevant to the resource issues of today as it was when our geologists first arrived in western Pennsylvania in 1884. Continuing in this proud heritage and tradition, the U.S. Geological Survey is moving confidently toward the next century, evolving organizationally and technologically to better meet the needs of our many constituencies. One major organizational change is the recent accession of employees from the former National Biological Service, who now form the Survey's fourth program division, the Biological Resources Division. These employees join forces with colleagues in our other three divisions: Water Resources, Geologic, and National Mapping. More than any other change in decades, the addition of this biological expertise creates new and exciting opportunities for scientific research and public service. This report provides an overview of recent activities in Pennsylvania conducted by the four program divisions and is intended to inform those interested in U.S. Geological Survey products and services. Additional information is available on our home page (at http://wwwpah2o.er.usgs.gov/). Together with numerous Federal, State, and local agencies and organizations who are our customers and partners, we at the U.S. Geological Survey look forward to providing continued scientific contributions and public service to Pennsylvania and the Nation.

Integrating Collaborative Learning Groups in the Large Enrollment Lecture

1998-12-01

Recent reforms for undergraduate education propose that students should work in teams to solve problems that simulate problems that research scientists address. In the context of an innovative large-enrollment course at Montana State University, faculty have developed a series of 15 in-class, collaborative learning group activities that provide students with realistic scenarios to investigate. Focusing on a team approach, the four principle types of activities employed are historical, conceptual, process, and open-ended activities. Examples of these activities include classifying stellar spectra, characterizing galaxies, parallax measurements, estimating stellar radii, and correlating star colors with absolute magnitudes. Summative evaluation results from a combination of attitude surveys, astronomy concept examinations, and focus group interviews strongly suggest that, overall, students are learning more astronomy, believe that the group activities are valuable, enjoy the less-lecture course format, and have significantly higher attendance rates. In addition, class observations of 48 self-formed, collaborative learning groups reveal that female students are more engaged in single-gender learning groups than in mixed gender groups.

The psychological effect of alopecia areata (AA) is well documented, but group interaction may help lessen this burden. We aimed to determine factors that draw patients with AA and their families to group events. Surveys were administered at the annual alopecia areata bowling social in 2015 and 2016. This event is a unique opportunity for children with AA and their families to meet others with the disease and connect with local support group resources from the Minnesota branch of the National Alopecia Areata Foundation. Data from 2015 and 2016 were combined. Comparisons of subgroups were performed using Fisher exact tests for response frequencies and percentages and two-sample t tests for mean values. An equal number of men and women participated in the study (n = 13 each). The average age was 41.1 years. There were no significant differences (p > 0.05) in survey responses based on respondent age or sex. Twenty-three (88.5%) attendees sought to connect with others with AA and met three or more people during the event. Seventeen (65.4%) also attended other support group events. Twelve respondents (46.2%) came to support a friend or family member. One hundred percent of attendees identified socializing with others with AA as important. Group interaction is an important source of therapeutic support for people with AA and their families. © 2017 Wiley Periodicals, Inc.

Oceanic active faults were classified into trench and in-land types, and a bottom survey was conducted on an aim of estimation on activity of a trench type oceanic active faults. For both sides of an oceanic active fault found at high precision sonic investigations in 1996 fiscal year, it was attempted from a record remained in sediments how a fault changed by a fault motion and how long time it acted. And, construction of a data base for evaluation of the active faults was promoted by generalizing the issued publications. As a result, it was found that a method to estimate a fault activity using turbidite in success at shallow sea could not easily be received at deep sea, and that as sedimentation method in deep sea changed largely by topography and so on, the turbidite did not play always a rule of key layer.

This chapter describes activities not directly concerned with the daily routine. These activities are nevertheless an important part of the Group's work as they encompass new projects and developments that require, in most cases, profound studies to prove their feasibility with respect to the radiation protection issues involved. In addition, there are technical and organizational developments in a quest not only to keep the standard of radiation protection at CERN high, but to ensure its constant improvement. All these activities are documented in Divisional Reports, Internal Reports and Technical Memoranda, and are listed in the tables of this chapter

2015-03-01

Full Text Available Introduction: Physical activity and a healthy diet are significant predictors of healthy ageing—they help the elderly maintain their physical and mental health, and prevent chronic diseases. Methods: The data for the empirical quantitative survey were collected on the sample of 218 elderly community-dwelling participants (aged 65 years or more, using a structured questionnaire for self-reporting. Data analyses were proceed with the bivariate statistics, and multivariate hierarchical cluster analysis. Results: Most respondents reported good dietary habits (83.1% and a satisfactory physical activity level (60.5%. On average, the elderly eat 3-4 meals per day (59.8% and engage in physical activity at least three times a week (58.6%, with interventions lasting 15 minutes or more (84.4 % and non-organized activity prevailing (96.2%. Ward’s method yielded three clusters with homogenous dietary and physical activity patterns: ‘Health Conscious’ (30.8%, ‘At Risk’ (42.7% and ‘Special Requirements’ (26.5%. Significant differences were identified between clusters and educational level (p = 0.001. Discussion and conclusions: In the future, special attention should be placed on the elderly group with a lower educational level and special dietary and physical activity requirements. Additional studies on representative samples are required for a comprehensive investigation into the lifestyle behaviours of elderly individuals.

Stierwalt, Sabrina; Haynes, Martha P.; Giovanelli, Riccardo; Martin, Ann M.; Kent, Brian R.; Saintonge, Amelie; Karachentsev, Igor D.; Karachentseva, Valentina E.

2009-01-01

We present the catalog of H I sources extracted from the ongoing Arecibo Legacy Fast ALFA (ALFALFA) extragalactic H I line survey, found within the sky region bounded by 9 h 36 m h 36 m and +08 0 0 . The H I catalog presented here for this 118 deg 2 region is combined with the ones derived from surrounding regions also covered by the ALFALFA survey to examine the large-scale structure in the complex Leo region. Because of the combination of wide sky coverage and superior sensitivity, spatial and spectral resolution, the ALFALFA H I catalog of the Leo region improves significantly on the numbers of low H I mass sources as compared with those found in previous H I surveys. The H I mass function of the Leo I group presented here is dominated by low-mass objects: 45 of the 65 Leo I members have M H I 8 M-odot, yielding tight constraints on the low-mass slope of the Leo I H I mass function. The best-fit slope is α ≅ -1.41 + 0.2 - 0.1. A direct comparison between the ALFALFA H I line detections and an optical search of the Leo I region proves the advantage of the ALFALFA strategy in finding low-mass, gas-rich dwarfs. These results suggest the existence of a significant population of low surface brightness, gas-rich, yet still very low H I mass galaxies, and may reflect the same type of morphological segregation as is seen in the Local Group. While the low-mass end slope of the Leo I H I mass function is steeper than that determined for luminosity functions of the group, the slope still falls short of the values predicted by simulations of structure formation in the lambda cold dark matter paradigm.

THEORETICAL PRINCIPLES OF PSYCHOLOGICAL ANALYSIS OF STUDENTS’ GROUP PROJECT ACTIVITY WHILE LEARNING FOREIGN LANGUAGE

Directory of Open Access Journals (Sweden)

Viktoriia Kalamazh

2016-06-01

Full Text Available In this research the theoretical principles of psychological analysis of group project activity of students in the process of learning foreign language are defined on the basis of subject-activity, socio-psychological and cognitive paradigms. The approaches of different authors to the understanding of the concept of project and in particular group project activity are considered. The difficulties of the theoretical analysis of this specific notion are indicated due to the considerable variety of subjects, types and forms of the pedagogical activity, academic disciplines regarding which the researches are being carried out. Not disclosed aspects of organizing the group project activity of students are being determined, among them is a project group as an autonomous subject of joint activity for the realization students’ project activity while learning a foreign language; forming psychological readiness of teacher and student to use project method; the role of metacognitive aspect in the surrounding, where the project activity is being carried out; group functioning through the project work as a subject of group examination. It has been indicated that the analysis of project activity as an innovative technology must include its assessment as a condition of student’s developing as a subject of learning activity, his personal, socio-psychological, intellectual and professional self-perfection. Three levels of subjectivity in group project activity are being distinguished: teacher; each particular student; and student project group. Interaction between teacher and student is based on subject-subject relations. An organization of a project activity while learning a foreign language is considered as the one in which the student is moving in order to get the manager position and to master the basis of expert knowledge. Hereby, the main stress is on the group role as a subject of group examination, and also on metacognitive character of the

The purpose of this study is to survey and assess radioactive contamination of foodstuffs in order to reduce the probability of intake of contaminated foodstuffs. Based on survey and assessment, final goal is to improve the public health by radiation protection. Sampled foodstuffs items are collected from the markets : one group are imported foodstuffs and the other group are domestic foodstuffs producted around nuclear facilities. After pretreatments such as drying, ashing, and homogenization, all samples were analyzed by gamma spectrometer system. The 137 Cs radionuclide was only measured among the regulation radionuclides ( 137 Cs, 134 Cs, 131 I) of food code. All radionuclides of the domestic foodstuffs collected around nuclear facilities were below Minimum Detectable Activity (MDA). But the activity concentrations of Inonotus obliquus (Chaga mushooms) from Russia ranged up to 171.27 (average value : 36.65) Bq/kg-fresh. In the case of blueberry jam, the radioactivity of 137 Cs is higher than expected value. Other samples are below MDA except some spices. Based on the previous and present results, it should be strengthen to survey for Inontus obliquus (Chaga mushooms), of which the radioactivity shows the range from MDA up to 800.01 Bq/kg-fresh. It should assess the public radiation exposure via food chain because it has the excess provability of the maximum permitted level of food code, which is regulation of KFDA. The development method based on international standard would be used at radioactive analysis as well as education of practical workers and it could be applied as the basis data for amending the analysis method of food code. Our country only surveys gamma emitting radionuclides till now but international organization or foreign countries for example EU survey alpha and beta emitting radionuclides as well as gamma emitting radionuclides. So our country should also research necessity of survey for alpha and beta emitting radionuclides

Active games require whole-body movement and may be an innovative tool to substitute sedentary pastime with more active time and may therefore contribute to adolescents' health. To inform strategies aimed at reducing sedentary behavior by replacing non-active with active gaming, perceptions and context of active and non-active gaming are explored. Six focus groups were conducted with adolescents 12-16 years old representing a range of education levels. A semistructured question route was used containing questions about perceptions and the context of gaming. The adolescents had positive attitudes toward active gaming, especially the social interactive aspect, which was greatly appreciated. A substantial number of adolescents enjoyed non-active games more than active ones, mainly because of better game controls and more diversity in non-active games. Active games were primarily played when there was a social gathering. Few game-related rules and restrictions at home were reported. Given the positive attitudes of adolescents and the limited restrictions for gaming at home, active videogames may potentially be used in a home setting as a tool to reduce sedentary behavior. However, to make active games as appealing as non-active games, attention should be paid to the quality, diversity, and sustainability of active games, as these aspects are currently inferior to those of traditional non-active games.

da Silva, Jodo Luis Almeida; Lopes, Marta Julia Marques

2006-06-01

It is a report on the group activities carried out with carriers of varicose ulcer in a health unit in Porto Alegre, Rio Grande do Sul, Brazil. The varicose ulcer presents factors, besides the biological ones, which interfere in the cicatrization, in the relapse cases and in its effective resolution. The proposed activities aimed at producing behavior changes with the intention of achieving self-care, providing information, socializing the participants, and stimulating cooperation, searching for joint solutions, aggregating interdisciplinary spirit and improving the care. Two groups have been formed and a thematic schedule established. The results have showed higher adhesion to the treatment, behavioral changes, and adapted and more effective attitudes of the health team.

Individuals with developmental disabilities may engage in automatically reinforced behaviors that may interfere with learning opportunities. Manipulation of motivating operations has been shown to reduce automatically maintained behavior in some individuals. Considering behavioral indicators of satiation may assist in identifying the point at which an abolishing operation has begun to effect behavior. The purpose of this study was to evaluate the effects of pre-session satiation of automatic reinforcement on subsequent levels of stereotypy and activity engagement during group activities for three males ages 5 to 13 years with developmental disabilities. Following functional analyses with analogue conditions, an alternating treatment design compared a pre-session access to stereotypy condition with a no-pre-session access condition prior to group activity sessions. Results indicated that pre-session satiation of the putative reinforcer produced by stereotypy was effective in decreasing stereotypy and increasing activity engagement during subsequent group activities for all participants. These findings add to the literature supporting the effectiveness of abolishing operations to decrease automatically maintained stereotypy. © The Author(s) 2013.

To analyze practice habits associated with the use, reversal and monitoring of nondepolarizing neuromuscular blocking agents (NMBAs) in dogs by different groups of veterinarians. Online anonymous survey to veterinarians. Data from 390 answered surveys. A questionnaire was sent to e-mail list servers of the American College of Veterinary Anesthesia and Analgesia (ACVAA-list), Sociedad Española de Anestesia y Analgesia Veterinaria (SEEAV-list), Colégio Brasileiro de Anestesiologia Veterinária (Brazilian College of Veterinary Anesthesiology; CBAV-list) and American College of Veterinary Ophthalmologists (ACVO-list) to elicit information regarding use of NMBAs and reversal agents, monitoring techniques, criteria for redosing, reversing and assessing adequacy of recovery of neuromuscular function. Binomial logistic regression was used to test for association between responses and group of veterinarians in selected questions. Veterinarians of the ACVO-list use NMBAs on a higher fraction of their caseload than other groups (all p < 0.0001). Subjective assessment (observation) of spontaneous movement, including spontaneous breathing, is the most common method for assessing neuromuscular function (43% of pooled responses); 18% of participants always reverse NMBAs, whereas 16% never reverse them. Restoration of neuromuscular function is assessed subjectively by 35% of respondents. Residual neuromuscular block is the most common concern regarding the use of NMBAs for all groups of veterinarians. Side effects of reversal agents (anticholinesterases) were of least concern for all groups. While most veterinarians are concerned about residual neuromuscular block, relatively few steps are implemented to reduce the risks of this complication, such as routine use of quantitative neuromuscular monitoring or routine reversal of NMBAs. These results suggest a limitation in transferring information among groups of veterinarians, or in implementing techniques suggested by scientific

Population surveys are frequently used to assess prevalence, correlates and health benefits of physical activity. However, nonsampling errors, such as question order effects, in surveys may lead to imprecision in self reported physical activity. This study examined the impact of modified question order in a commonly used physical activity questionnaire on the prevalence of sufficient physical activity. Data were obtained from a telephone survey of adults living in Queensland, Australia. A total of 1243 adults participated in the computer-assisted telephone interview (CATI) survey conducted in July 2008 which included the Active Australia Questionnaire (AAQ) presented in traditional or modified order. Binary logistic regression analyses was used to examine relationships between question order and physical activity outcomes. Significant relationships were found between question order and sufficient activity, recreational walking, moderate activity, vigorous activity, and total activity. Respondents who received the AAQ in modified order were more likely to be categorized as sufficiently active (OR = 1.28, 95% CI 1.01-1.60). This study highlights the importance of question order on estimates of self reported physical activity. This study has shown that changes in question order can lead to an increase in the proportion of participants classified as sufficiently active.

Craike, Melinda; Wiesner, Glen; Hilland, Toni A; Bengoechea, Enrique Garcia

2018-05-15

People from socioeconomically disadvantaged population groups are less likely to be physically active and more likely to experience adverse health outcomes than those who are less disadvantaged. In this umbrella review we examined across all age groups, (1) the effectiveness of interventions to improve physical activity among socioeconomically disadvantaged groups, (2) the characteristics of effective interventions, and (3) directions for future research. PubMed/MEDLINE and Scopus were searched up to May 2017 to identify systematic reviews reporting physical activity interventions in socioeconomically disadvantaged populations or sub-groups. Two authors independently conducted study screening and selection, data extraction (one author, with data checked by two others) and assessment of methodological quality using the 'Assessment of Multiple Systematic Reviews' scale. Results were synthesized narratively. Seventeen reviews met our inclusion criteria, with only 5 (30%) reviews being assessed as high quality. Seven (41%) reviews focused on obesity prevention and an additional four focused on multiple behavioural outcomes. For pre school children, parent-focused, group-based interventions were effective in improving physical activity. For children, school-based interventions and policies were effective; few studies focused on adolescents and those that did were generally not effective; for adults, there was mixed evidence of effectiveness but characteristics such as group-based interventions and those that focused on physical activity only were associated with effectiveness. Few studies focused on older adults. Across all ages, interventions that were more intensive tended to be more effective. Most studies reported short-term, rather than longer-term, outcomes and common methodological limitations included high probability of selection bias, low response rates, and high attrition. Interventions can be successful at improving physical activity among children from

Activity groups for persons with dementia: Personal predictors of participation, engagement and mood.

This study examined the relationship between personal characteristics and attendance, engagement, sleep, and mood outcomes of persons with dementia participating in group activities. The purpose of this study is to examine which persons with dementia benefit most from group interventions. Sixty-nine persons with dementia were observed by research and therapeutic recreation staff during 10 types of group activities (reading aloud with discussion, choral-singing, baking, creative storytelling, brain games, active games, exercise, reminiscence poetry, holiday newsletter, and holiday discussions) on multiple outcomes (attendance duration, sleep, engagement, active participation, attitude, and positive mood). Correlations between these outcomes and personal characteristics (demographics, functional and medical characteristics, personal preferences for group activities) were conducted. Variables with significant correlations were then entered into regression analyses. Many of the personal characteristics were significantly correlated with the outcomes. Cognitive function was the most consistent predictor of all outcomes. Personal characteristics, particularly cognitive function, can predict the responses of persons with dementia during group activities. Copyright © 2017 Elsevier B.V. All rights reserved.

Full Text Available OBJECTIVES: The Brazilian scientific production in the pediatrics field has been increasing significantly. It is important to identify the distribution and activity of these groups in the country and the main study areas, contributing with data for better resource allocation by institutions. METHODS: An active research was conducted in the National Council of Technological and Scientific Development (Conselho Nacional de Desenvolvimento Científico e Tecnológico [CNPq] website, using as filters the macro area of the research group (Health Sciences, the area (Medicine, and descriptors related to pediatrics. Research lines and main area of pediatric research groups were classified according to the subject predominantly studied by each group. The scientific production of the leader of the pediatric research group between 2011 and 2014 was also analyzed. RESULTS: Most pediatric research groups in Brazil have more than five years of activity and are concentrated in the Southeast and South regions of the country; São Paulo, Rio Grande do Sul, and Minas Gerais are the states with most groups. Of the 132 specific pediatric research groups analyzed, 14.4% have lines of research in multiple areas and 11.4% in child and adolescent health. Among the 585 lines of research of these groups, the most prevalent areas were: oncology, infectious diseases, epidemiology, and gastroenterology. CONCLUSIONS: The pediatric research groups in Brazil have relevant scientific production, including works published in international publications, and are concentrated in regions with higher socioeconomic index. Most groups registered in CNPq started their activity in the last five years (46%, reflecting the recent growth of scientific production in this area.

Prior research suggests that racial minority groups in the United States are more vulnerable to develop a gambling disorder than whites. However, no national survey on gambling disorders exists that has focused on ethnic differences. Analyses of this study were based on the National Epidemiologic Survey on Alcohol and Related Conditions, a large (N=43,093) nationally representative survey of the adult (> or =18 years of age) population residing in households during 2001-2002 period. Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-Text Revision diagnoses of pathological gambling, mood, anxiety, drug use, and personality disorders were based on the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV Version. Prevalence rates of disordered gambling among blacks (2.2%) and Native/Asian Americans (2.3%) were higher than that of whites (1.2%). Demographic characteristics and psychiatric comorbidity differed among Hispanic, black, and white disordered gamblers. However, all racial and ethnic groups evidenced similarities with respect to symptom patterns, time course, and treatment seeking for pathological gambling. The prevalence of disordered gambling, but not its onset or course of symptoms, varies by racial and ethnic group. These varying prevalence rates may reflect, at least in part, cultural differences in gambling and its acceptability and accessibility. These data may inform the need for targeted prevention strategies for high-risk racial and ethnic groups.

Why some do but most don't. Barriers and enablers to engaging low-income groups in physical activity programmes: a mixed methods study

Full Text Available Abstract Background The beneficial effect of physical activity for the prevention of a range of chronic diseases is widely acknowledged. These chronic conditions are most pronounced in economically disadvantaged groups where physical activity levels are consistently lower, yet this group is particularly difficult to recruit and retain in physical activity programmes. This study examined the perceptions of participants, non-participants, and exercise leaders in a low-income area regarding barriers, motives, and enabling factors for organised physical activity with a view to improving recruitment and retention. Methods A mixed methods research approach was adopted to guide data collection and analysis. A survey, incorporating the Motivation for Physical Activity Measure - Revised (MPAM-R, was used to assess the motivations of 152 physical activity session participants in a highly deprived suburban neighbourhood. The MPAM-R data were analysed using t tests, analyses of variance to estimate age, body mass index, and activity mode differences and Pearson's correlation coefficient to address associations. Semi-structured interviews were also conducted with 33 local residents who did not participate in activity sessions and with 14 activity session leaders. All interviews were audio-taped, transcribed verbatim and analyzed using an inductive thematic approach. Results Participants reported cost, childcare, lack of time and low awareness as barriers to joining activity classes. The need for support, confidence and competence in order to take up activity was widely expressed, particularly among women. Once people are active, high levels of social interaction, interest and enjoyment are associated with improved levels of retention, with different types of physical activity scoring differently on these factors. Conclusions This study suggests that some factors such as cost, the fear of 'walking in alone', accessibility of facilities, and appropriate

Human valacyclovirase (hVACVase) is a prodrug-activating enzyme for amino acid prodrugs including the antiviral drugs valacyclovir and valganciclovir. In hVACVase-catalyzed reactions, the leaving group of the substrate corresponds to the drug moiety of the prodrug, making the leaving group effect essential for the rational design of new prodrugs targeting hVACVase activation. In this study, a series of valine esters, phenylalanine esters, and a valine amide were characterized for the effect of the leaving group on the efficiency of hVACVase-mediated prodrug activation. Except for phenylalanine methyl and ethyl esters, all of the ester substrates exhibited a relatively high specificity constant (k(cat)/K(m)), ranging from 850 to 9490 mM(-1)·s(-1). The valine amide Val-3-APG exhibited significantly higher K(m) and lower k(cat) values compared to the corresponding ester Val-3-HPG, indicating poor specificity for hVACVase. In conclusion, the substrate leaving group has been shown to affect both binding and specific activity of hVACVase-catalyzed activation. It is proposed that hVACVase is an ideal target for α-amino acid ester prodrugs with relatively labile leaving groups while it is relatively inactivate toward amide prodrugs.

The detailed mechanisms leading to collective dynamics in groups of animals and insect are still poorly understood. A recent study by Simpson et. al. suggests cannibalism as a driving mechanism for coordinated migration of mormon crickets [1]. Based on this result we propose a simple generic model of brownian particles interacting by asymmetric, non-conservative collisions accounting for cannibalistic behavior and the corresponding avoidance strategy. We discuss our model in one and two dimensions and show that a certain type of collisions drives the system out of equilibrium and leads to coordinated active motion of groups.[1] Stephen J.

Elderly population is considered as a vulnerable group and prone to develop multiple medical problems. This aging population is rapidly increasing in developing countries especially in Thailand. Methods: This study was a quasi-experimental study to evaluate the effectiveness of Group-Mediated Lifestyle Physical Activity program on change health benefit in physical activity among elderly people by using validated and reliable Global Physical Activity Questionnaire-GPAQv2. The study was conducted in Phranakhonsiayutthaya district, Ayutthaya province due to its population being the second highest elderly in the Central Region of Thailand. A total of 102 persons of age 60 and over who could read and write Thai language were selected purposively. However, 52 elderly were enrolled in the intervention group and 50 were enrolled for the control group. General Linear Model repeated-measures ANOVA was used to evaluate the effects of Group-Mediated Lifestyle Physical Activity (GLPA) program on change health benefit in physical activity among elderly. Results: Overall health benefit at baseline were similar between intervention and control group and found statistically non-significant with p-value 0.638 (>0.05). However, the mean score of health benefit was 23.21 ± 29.23 in intervention group and 20.74 ± 23.18 in control group. One third of participants of intervention group had not found health benefit due to physical activity while in control group this number was more than half. After elderly received Group-Mediated Lifestyle Physical Activity program intervention for 6 month found significant statistical differences as compared with mean score at baseline (health benefit 6 month, intervention group =40.7 ± 34.28 and control group =4.56 ± 8.79). Conclusion: The effect of Group-Mediated Lifestyle Physical Activity program change intervention was statistically significant in health benefit after intervention program between intervention and control group.

Increasingly, Web-based health applications are developed for the prevention and management of chronic diseases. However, their reach and utilization is often disappointing. Qualitative evaluations post-implementation can be used to inform the optimization process and ultimately enhance their adoption. In current practice, such evaluations are mainly performed with end-user surveys. However, a review approach by experts in a focus group may be easier to administer and might provide similar results. The aim of this study was to assess whether industrial design engineers in a focus group would address the same issues as end users in a Web-based survey when evaluating a commercial Web-based health risk assessment (HRA) with tailored feedback. Seven Dutch companies used the HRA as part of their corporate health management strategy. Employees using the HRA (N=2289) and 10 independent industrial designers were invited to participate in the study. The HRA consisted of four components: (1) an electronic health questionnaire, (2) biometric measurements, (3) laboratory evaluation, and (4) individually tailored feedback generated by decision support software. After participating in the HRA as end users, both end users and designers evaluated the program. End users completed an evaluation questionnaire that included a free-text field. Designers participated in a focus group discussion. Constructs from user satisfaction and technology acceptance theories were used to categorize and compare the remarks from both evaluations. We assessed and qualitatively analyzed 294 remarks of 189 end users and 337 remarks of 6 industrial designers, pertaining to 295 issues in total. Of those, 137 issues were addressed in the end-user survey and 148 issues in the designer focus group. Only 7.3% (10/137) of the issues addressed in the survey were also addressed in the focus group. End users made more remarks about the usefulness of the HRA and prior expectations that were not met. Designers made

We use Chandra data to study the incidence and properties of active galactic nuclei (AGNs) in 16 intermediate redshift (0.5 < z < 1.1) X-ray-selected galaxy groups in the Chandra Deep Field-South. We measure an AGN fraction of f(L X,H >10 42 ;M R <−20)=8.0 −2.3 +3.0 % at z-bar ∼0.74, approximately a factor of two higher than the AGN fraction found for rich clusters at comparable redshift. This extends the trend found at low redshift for groups to have higher AGN fractions than clusters. Our estimate of the AGN fraction is also more than a factor of three higher than that of low redshift X-ray-selected groups. Using optical spectra from various surveys, we also constrain the properties of emission-line selected AGNs in these groups. In contrast to the large population of X-ray AGNs (N(L X, H > 10 41 erg s –1 ) = 25), we find only four emission-line AGNs, three of which are also X-ray bright. Furthermore, most of the X-ray AGNs in our groups are optically dull (i.e., lack strong emission-lines), similar to those found in low redshift X-ray groups and clusters of galaxies. This contrasts with the AGN population found in low redshift optically selected groups which are dominated by emission-line AGNs. The differences between the optically and X-ray-selected AGNs populations in groups are consistent with a scenario where most AGNs in the densest environments are currently in a low accretion state.

Less than half of all U.S. adults meet the 2008 Physical Activity Guidelines. Leader behaviors and group cohesion have been associated with increased participation or adherence in sports team and exercise class settings. Physical activity interventions in community settings that encompass these factors may enhance intervention adherence. The purpose of this study is to examine the impact of Community Health Promoter leader behaviors and group cohesion on participation in a walking group intervention among racially/ethnically diverse adults in low to moderate-income communities in Detroit, Michigan. Data for the current study were drawn from the Walk Your Heart to Health (WYHH) data set. WYHH was a multisite cluster RCT with a lagged intervention and outcome measurements at baseline and 4, 8, and 32 weeks. Pooled survey data from both intervention arms were used for the current study. Data were analyzed between August 2013 and October 2014. A total of 603 non-Hispanic black, non-Hispanic white, and Hispanic adults across five cohorts that began the 32-week WYHH intervention between March 2009 and October 2011. The intervention was a 32-week walking group program hosted by community- and faith-based organizations and facilitated by Community Health Promoters. Walking groups met three times per week for 90 minutes per session. To promote participation in or adherence to WYHH, Community Health Promoters used evidence-based strategies to facilitate group cohesion. Group members assumed increasing leadership responsibility for facilitating sessions over time. Participation in WYHH as measured by consistency of attendance. Community Health Promoter leader behaviors were positively associated with participation in WYHH. Social but not task cohesion was significantly associated with consistent participation. Social cohesion may mediate the relationship between leader behaviors and walking group participation. Providing leaders with training to build socially cohesive groups

An investigation of the functional groups on the surface of activated carbons

Directory of Open Access Journals (Sweden)

MARYTE DERVINYTE

2004-05-01

Full Text Available Activated carbons were produced in the laboratory from wood using a 20-run Plackett–Burman experimental design for 19 factors. The obtained batches of activated carbon were analysed by potentiometric titration and FTIR spectroscopy to determine the surface functional groups. The results obtained by potentiometric titration displayed the distribution of individual acidity constants of those groups in the pK range. Considering this parameter, the surface functional groups were divided into carboxyl, lactone and phenol. The linear regression equations reflecting the influence of each operation used for the synthesis on the amount of these functional groups in the obtained activated carbons were generated. The FTIR spectra were used in parallel for the evaluation of the amount and the type of the surface functional groups. Relationships between the two data sets obtained by potentiometric titration and FTIR spectroscopy were evaluated by correlation analysis. It was established that the amount of surface functional groups determined by potentiometric titration positively correlates with the intensity of the peaks of hydrophilic functional groups in the FTIR spectra. At the same time, the negative correlation between potentiometrically determined amount of surface functional groups and the intensity of peaks of hydrophobic functional groups was observed. Most probably, these non-polar formations can take part in the interaction of carbon surface with H+/OH- ions and diminish the strength of existent functional groups.

Gao, Yong; Zhu, Weimo

2011-05-01

The purpose of this study was to identify subgroup-sensitive physical activities (PA) using differential item functioning (DIF) analysis. A sub-unweighted sample of 1857 (men=923 and women=934) from the 2003-2004 National Health and Nutrition Examination Survey PA questionnaire data was used for the analyses. Using the Mantel-Haenszel, the simultaneous item bias test, and the ANOVA DIF methods, 33 specific leisure-time moderate and/or vigorous PA (MVPA) items were analyzed for DIF across race/ethnicity, gender, education, income, and age groups. Many leisure-time MVPA items were identified as large DIF items. When participating in the same amount of leisure-time MVPA, non-Hispanic blacks were more likely to participate in basketball and dance activities than non-Hispanic whites (NHW); NHW were more likely to participated in golf and hiking than non-Hispanic blacks; Hispanics were more likely to participate in dancing, hiking, and soccer than NHW, whereas NHW were more likely to engage in bicycling, golf, swimming, and walking than Hispanics; women were more likely to participate in aerobics, dancing, stretching, and walking than men, whereas men were more likely to engage in basketball, fishing, golf, running, soccer, weightlifting, and hunting than women; educated persons were more likely to participate in jogging and treadmill exercise than less educated persons; persons with higher incomes were more likely to engage in golf than those with lower incomes; and adults (20-59 yr) were more likely to participate in basketball, dancing, jogging, running, and weightlifting than older adults (60+ yr), whereas older adults were more likely to participate in walking and golf than younger adults. DIF methods are able to identify subgroup-sensitive PA and thus provide useful information to help design group-sensitive, targeted interventions for disadvantaged PA subgroups. © 2011 by the American College of Sports Medicine

Barriers for recess physical activity: a gender specific qualitative focus group exploration

DEFF Research Database (Denmark)

Pawlowski, Charlotte Skau; Tjørnhøj-Thomsen, Tine; Schipperijn, Jasper

Background: Many children, in particular girls, do not reach the recommended amount of daily physical activity. School recess provides an opportunity for both boys and girls to be physically active, but barriers to recess physical activity are not well understood. This study explores gender...... (53 boys) from fourth grade, with a mean age of 10.4 years. The focus groups included an open group discussion, go-along group interviews, and a gender segregated post-it note activity. A content analysis of the post-it notes was used to prioritize the children´s perceived barriers. This was verified...... barriers, there were both inter- and intra-gender differences in the children´s perceptions of these barriers. Weather was a barrier for all children, apart from the most active boys. Conflicts were perceived as a barrier particularly for those boys who played ballgames. Girls said they would like to have...

We present a public catalog of galaxy groups constructed from the spectroscopic sample of galaxies in the fourth data release from the Deep Extragalactic Evolutionary Probe 2 (DEEP2) Galaxy Redshift Survey, including the Extended Groth Strip (EGS). The catalog contains 1165 groups with two or more members in the EGS over the redshift range 0 < z < 1.5 and 1295 groups at z > 0.6 in the rest of DEEP2. Twenty-five percent of EGS galaxies and fourteen percent of high-z DEEP2 galaxies are assigned to galaxy groups. The groups were detected using the Voronoi-Delaunay method (VDM) after it has been optimized on mock DEEP2 catalogs following similar methods to those employed in Gerke et al. In the optimization effort, we have taken particular care to ensure that the mock catalogs resemble the data as closely as possible, and we have fine-tuned our methods separately on mocks constructed for the EGS and the rest of DEEP2. We have also probed the effect of the assumed cosmology on our inferred group-finding efficiency by performing our optimization on three different mock catalogs with different background cosmologies, finding large differences in the group-finding success we can achieve for these different mocks. Using the mock catalog whose background cosmology is most consistent with current data, we estimate that the DEEP2 group catalog is 72% complete and 61% pure (74% and 67% for the EGS) and that the group finder correctly classifies 70% of galaxies that truly belong to groups, with an additional 46% of interloper galaxies contaminating the catalog (66% and 43% for the EGS). We also confirm that the VDM catalog reconstructs the abundance of galaxy groups with velocity dispersions above {approx}300 km s{sup -1} to an accuracy better than the sample variance, and this successful reconstruction is not strongly dependent on cosmology. This makes the DEEP2 group catalog a promising probe of the growth of cosmic structure that can potentially be used for cosmological tests.

1988-01-01

The report summarizes the results of the activities of the CONT Expert Group, a subgroup of the CEC Fast Reactor Safety Working Group (SWG). The CONT group's work has over the last 12 years (1975-87) covered a wide spectrum of problems related to the behaviour of the primary containment of a sodium-cooled fast reactor following an accident releasing a large amount of mechanical energy. In particular the CONT group followed closely the code development and validation (COVA) programme carried out at the JRC Ispra. This activity also included an assessment of related material programmes. From a comparison of containment codes and a sensitivity analysis, it was concluded that the codes developed in the EC Member States and at the JRC Ispra allow to treat the consequences of a hypothetical core-disruptive accident on primary containment with adequate accuracy. Consequently the the group considered its mandate fulfilled and terminated its activities

So-called few-group neutron data have to be used as input data in core models (such as DYN3D) calculating the reactor behaviour. A survey is given of qualified data libraries for the reactor cores of Russian VVER. The information about primary data used in group data generation and the accuracy reached by the cell codes is compiled in tables. To assess the quality of the data, comparisons have been made between measured and calculated reactor parameters. The information available does not show significant differences concerning the quality of the data libraries. (orig.) [de

Previous studies have examined participation in specific leisure-time physical activities (PA) among US adults. The purpose of this study was to identify specific activities that contribute substantially to total volume of leisure-time PA in US adults. Proportion of total volume of leisure-time PA moderate-equivalent minutes attributable to 9 specific types of activities was estimated using self-reported data from 21,685 adult participants (≥ 18 years) in the National Health and Nutrition Examination Survey 1999-2006. Overall, walking (28%), sports (22%), and dancing (9%) contributed most to PA volume. Attributable proportion was higher among men than women for sports (30% vs. 11%) and higher among women than men for walking (36% vs. 23%), dancing (16% vs. 4%), and conditioning exercises (10% vs. 5%). The proportion was lower for walking, but higher for sports, among active adults than those insufficiently active and increased with age for walking. Compared with other racial/ethnic groups, the proportion was lower for sports among non-Hispanic white men and for dancing among non-Hispanic white women. Walking, sports, and dance account for the most activity time among US adults overall, yet some demographic variations exist. Strategies for PA promotion should be tailored to differences across population subgroups.

Development and implementation of a local government survey to measure community supports for healthy eating and active living

Directory of Open Access Journals (Sweden)

Latetia V Moore

2017-06-01

Full Text Available The ability to make healthy choices is influenced by where one lives, works, shops, and plays. Locally enacted policies and standards can influence these surroundings but little is known about the prevalence of such policies and standards that support healthier behaviors. In this paper, we describe the development of a survey questionnaire designed to capture local level policy supports for healthy eating and active living and findings and lessons learned from a 2012 pilot in two states, Minnesota and California, including respondent burden, survey sampling and administration methods, and survey item feasibility issues. A 38-item, web-based, self-administered survey and sampling frame were developed to assess the prevalence of 22 types of healthy eating and active living policies in a representative sample of local governments in the two states. The majority of respondents indicated the survey required minimal effort to complete with half taking <20 min to complete the survey. A non-response follow-up plan including emails and phone calls was required to achieve a 68% response rate (versus a 37% response rate for email only reminders. Local governments with larger residential populations reported having healthy eating and active living policies and standards more often than smaller governments. Policies that support active living were more common than those that support healthy eating and varied within the two states. The methods we developed are a feasible data collection tool for estimating the prevalence of municipal healthy eating and active living policies and standards at the state and national level.

2012-01-01

Full Text Available Purpose. To identify whether non-overweight students were different from their overweight or obese peers with respect to diet, suboptimal meal behaviours, and physical activity using a self-administered web-based survey. Methods. 4097 adolescents living in Alberta, Canada completed Web-SPAN (Web Survey of Physical Activity and Nutrition. Students were classified as overweight or obese, and differences were described in terms of nutrient intakes, physical activity, and meal behaviours. Results. Non-overweight students consumed significantly more carbohydrate and fibre, and significantly less fat and high calorie beverages, and had a higher frequency of consuming breakfast and snacks compared to overweight or obese students. Both non-overweight and overweight students were significantly more active than obese students. Conclusions. This research supports the need to target suboptimal behaviours such as high calorie beverage consumption, fat intake, breakfast skipping, and physical inactivity. School nutrition policies and mandatory physical education for all students may help to improve weight status in adolescents.

We also confirm that the VDM catalog reconstructs the abundance of galaxy groups with velocity dispersions above ∼300 km s –1 to an accuracy better than the sample variance, and this successful reconstruction is not strongly dependent on cosmology. This makes the DEEP2 group catalog a promising probe of the growth of cosmic structure that can potentially be used for cosmological tests.

This study focused on the perceived climate for LGBT youth and other minority groups in physical activity settings. A large sample of undergraduates and a selected sample including student teachers/interns and a campus Pride group completed a school climate survey and rated the climate in three physical activity settings (physical education, organized sport, exercise). Overall, school climate survey results paralleled the results with national samples revealing high levels of homophobic remarks and low levels of intervention. Physical activity climate ratings were mid-range, but multivariate analysis of variation test (MANOVA) revealed clear differences with all settings rated more inclusive for racial/ethnic minorities and most exclusive for gays/lesbians and people with disabilities. The results are in line with national surveys and research suggesting sexual orientation and physical characteristics are often the basis for harassment and exclusion in sport and physical activity. The current results also indicate that future physical activity professionals recognize exclusion, suggesting they could benefit from programs that move beyond awareness to skills and strategies for creating more inclusive programs.

Full Text Available Study aim: Research suggests that physical activity rates decline sharply after high school. The pattern of activity or inactivity during college tends to persist into adulthood. A critical need exists for examination of strategies to engage college-age students in physical activity habits. One way to do this is through physical activity courses offered in colleges. This study examines the relationship between perceptions of a caring psychological climate and group connectedness, enjoyment, and attitudes toward classmates and the instructor in group physical activity courses. Material and methods: Participants were 174 students (107 males and 67 females; Mage = 21.71 enrolled in exercise, martial arts, and sports courses at a large university in the Mountain West. Results: Perceptions of a caring climate were significantly related to enhanced feelings of group connectedness, heightened enjoyment, and more positive attitudes toward classmates and instructor. Discussion: These findings suggest that a strategy to foster engagement in physical activity courses on campus is to train instructors to value, support, and welcome students.

Full Text Available Cross-group friendship is an important element in regard to reducing prejudice and increasing positive interracial interactions among young adults. In order to facilitate the formation of cross-group friendships, organized activity participation (e.g., community service and school-based extracurricular activities may provide an environment that supports positive cross-cultural interactions and contacts. The sample used for this study consisted of 601 college students. We tested whether participation in an organized activity contributes to the formation of cross-group friendships. The results of this study indicate that community service and school-based extracurricular activities significantly contribute to the formation of cross-group friendships among young adults. The findings also suggest that a variety of organized activities should be developed and implemented to facilitate cross-group friendships. We also discuss the practical implications of these findings.

Although patellofemoral instability is among the most prevalent knee disorders, the management of patients with this condition is complex and remains variable, given the lack of long-term, high-level clinical outcome studies to compare various operative and nonoperative modalities. To discover a consensus within treatment controversies in patellofemoral instability among experienced knee surgeons with a specific interest in the patellofemoral joint. Expert opinion; Level of evidence, 5. A 3-step modified Delphi technique was used to establish a consensus. A 34-question, case-based online survey regarding patellofemoral instability was distributed to all active members of the International Patellofemoral Study Group. Consensus statements were generated if at least 66% of the respondents agreed and then redistributed to the same panel. Modifications to the consensus statements were made based on the iterative feedback process until no discordance was encountered in the third stage. Eight consensus statements were achieved. Nonoperative management is the current standard of care for a first-time dislocation in the absence of an osteochondral fragment or loose body requiring excision (100% agreement). In patients with a first-time dislocation with an operative osteochondral fracture requiring excision or repair, patellar instability should be addressed concurrently (89% agreement). Recurrent instability should be treated surgically, with most surgeons favoring medial reconstruction (77%-86% agreement). While there is general agreement that bony procedures should be performed to correct underlying bony deformities, there is no consensus regarding the most appropriate type of procedure performed. Lateral release should not be performed in isolation for the treatment of patellar instability (89% agreement). Despite the consensus generated in this study, our current understanding remains limited by a lack of high-level evidence as well as the numerous complex variables

Keeping horses in groups is widely recommended but limited information is available about how this is implemented in practice. The aim of this survey was to describe how horses are kept in the Nordic countries in relation to sex, age, breed, and equestrian discipline and to assess owners' attitudes toward keeping horses in groups. Horse owners in Denmark, Finland, Norway, and Sweden were approached using a web-based questionnaire, which was translated into 4 languages and distributed online via equestrian forums, organizations, and social media. The number of respondents was 3,229, taking care of 17,248 horses. Only 8% of horses were never kept in groups, 47% were permanently grouped for 24 h/d, and 45% were stabled singly but grouped during turnout. Yearlings were most often permanently kept in groups (75%), mares and geldings more commonly during parts of the day (50 and 51%, respectively), and stallions were often kept alone (38%). Icelandic horses were more likely to be permanently kept in groups (36%) than warmbloods (16%) and ponies (15%). Twice as many competition horses (51%) were never grouped compared with horses used for breeding (20%) or leisure purposes (15%). The majority of respondents (86%) strongly agreed that group housing benefits horse welfare and that it is important for horses to have the company of conspecifics (92%). Nevertheless, not all horses were kept in groups, showing that attitudes toward group housing may not necessarily reflect current management. The risk of injury was a concern of many respondents (45%), as was introducing unfamiliar horses into already established groups (40%) and challenges in relation to feeding in groups (44%). Safety of people (23%) and difficulties handling group-kept horses (19%) were regarded as less problematic. Results suggest that the majority of horses have the possibility to freely interact with other horses, either as fulltime members of a group during 24 h/d or during turnout. Future research should

The aim of this paper is to report the R and D activities of the ESARDA Working Group on Techniques and Standards for Non-Destructive Analysis (NDA), as well as to discuss the role and possibilities of the group in the modern R and D scenario in safeguards and non-proliferation. The main tasks of the ESARDA NDA Working have been identified as being to: Define needs for procedural standards and reference materials; Design and manage the production and characterisation of reference materials; Assess and contribute to improving the performances of NDA techniques; Set up and maintain a list of NDA instruments and methods currently used for Safeguards purposes; and, through the above activities, assist Operators and Safeguards Authorities in their duty of Safeguards implementation. Members and observers appointed to the working group represent plant operators, the nuclear industry, R and D laboratories, NDA instrument developers and both safeguards control authorities. The participation of major European plant operators and of the EURATOM Safeguards Directorate and IAEA has always been assured and contributes to the good outcome of the WG activities. The ongoing R and D activities of the NDA Working Group are: Monte Carlo performance intercomparisons; 242 Pu accuracy assessment and improvement; NDA Sampling errors; General NDA performance evaluations. Some milestones have recently been reached: The 242 Pu uncertainty improvement project is coming to an end with the issuing of a new isotopic correlation; The NCC 'reals' evaluation and the Monte Carlo round robin is producing its first results; The Uranium Enrichment Round Robin Exercise has been completed; The waste drum standards are being characterised and constructed: they will be available by spring 1998. The round robin amongst laboratories will then start: summer 1998. Future activities comprise, beside the above issues, technical problems linked with the new challenges posed by new regimes of safeguards and non

Twenty years after the advent of combined antiretroviral therapies (ARTs), there is a growing need for up-to-date information about the daily experience of people living with HIV (PLWH). This study aimed to investigate the relationship between socioepidemiological groups and the types of bothersome symptoms reported by PLWH participating in a national survey in France. We analyzed self-reported bothersome symptoms in a representative sample of PLWH (ANRS-VESPA2 survey), most of whom were receiving ART treatment. PLWH (N = 2505) were grouped into three clusters according to the number of bothersome symptoms reported: Cluster A (low number, n = 1848), Cluster B (moderate number, n = 271), and Cluster C (high number, n = 386). Individuals in Cluster A (low number of bothersome symptoms) were less likely to report all the symptom types investigated. Psychological, sexual, and general symptoms were more likely to be reported in Cluster B (moderate number), whereas gastric-, pain-, and appearance-related symptoms were more likely in Cluster C (high number). In multivariate analyses, women not natives of Sub-Saharan Africa and former/active female injecting drug users were more likely to report a medium or high number of symptoms, and lower adherence to ART. Combining new biomedical strategies with coping mechanisms and providing better support to socially vulnerable PLWH may improve this population's quality of health and daily life.

This technical report describes progress on the DOE sponsored project "New Horizons in C-F Activation by Main Group Electrophiles" during the period of 09/15/2010 – 08/31/2015. The main goal of this project was to develop improved catalysts for conversion of carbon-fluorine bonds in potentially harmful compounds. The approach involved combining of a highly reactive positively charged main-group compound with a highly unreactive negatively charged species (anions) as a way to access potent catalysts for carbon-fluorine bond activation. This report details progress made in improving synthetic pathways to a variety of new anions with improved properties and analysis of their potential in catalysis.

Pro-Lie Groups: A Survey with Open Problems

Directory of Open Access Journals (Sweden)

Karl H. Hofmann

2015-07-01

Full Text Available A topological group is called a pro-Lie group if it is isomorphic to a closed subgroup of a product of finite-dimensional real Lie groups. This class of groups is closed under the formation of arbitrary products and closed subgroups and forms a complete category. It includes each finite-dimensional Lie group, each locally-compact group that has a compact quotient group modulo its identity component and, thus, in particular, each compact and each connected locally-compact group; it also includes all locally-compact Abelian groups. This paper provides an overview of the structure theory and the Lie theory of pro-Lie groups, including results more recent than those in the authors’ reference book on pro-Lie groups. Significantly, it also includes a review of the recent insight that weakly-complete unital algebras provide a natural habitat for both pro-Lie algebras and pro-Lie groups, indeed for the exponential function that links the two. (A topological vector space is weakly complete if it is isomorphic to a power RX of an arbitrary set of copies of R. This class of real vector spaces is at the basis of the Lie theory of pro-Lie groups. The article also lists 12 open questions connected to pro-Lie groups.

Surveying patients is increasingly important for evaluating and improving health care delivery, but practical survey strategies during routine care activities have not been available. We examined the feasibility of conducting routine patient surveys in a primary care clinic using commercially available technology (Web-based survey creation, deployment on tablet computers, cloud-based management of survey data) to expedite and enhance several steps in data collection and management for rapid quality improvement cycles. We used a Web-based data management tool (survey creation, deployment on tablet computers, real-time data accumulation and display of survey results) to conduct four patient surveys during routine clinic sessions over a one-month period. Each survey consisted of three questions and focused on a specific patient care domain (dental care, waiting room experience, care access/continuity, Internet connectivity). Of the 727 available patients during clinic survey days, 316 patients (43.4%) attempted the survey, and 293 (40.3%) completed the survey. For the four 3-question surveys, the average time per survey was overall 40.4 seconds, with a range of 5.4 to 20.3 seconds for individual questions. Yes/No questions took less time than multiple choice questions (average 9.6 seconds versus 14.0). Average response time showed no clear pattern by order of questions or by proctor strategy, but monotonically increased with number of words in the question (30 words)-8.0, 11.8, 16.8, seconds, respectively. This technology-enabled data management system helped capture patient opinions, accelerate turnaround of survey data, with minimal impact on a busy primary care clinic. This new model of patient survey data management is feasible and sustainable in a busy office setting, supports and engages clinicians in the quality improvement process, and harmonizes with the vision of a learning health care system.

Increasing workload in health professionals and resulting health consequences have frequently been reported. We analysed the results from an employee attitude survey within a network of workplace health promotion and compared three occupational groups of a university hospital with two samples of employees of other industries. The survey was conducted in the years 2005, 2006 and 2007 using a standardized method, addressing 1748 employees of six companies. In order to compare specific occupational groups, both within the hospital and amongst different companies, five occupational groups were selected (medical profession, nursing service and administration of the hospital, academics of another company and employees of a financial service provider). Some results were specific for an occupational group, such as lower back pain and skin diseases in nurses and exhaustion in clinicians. Regarding several items the responses of employees of the hospital's administration were similar to that of the medical professionals and differed significantly from the responses of administrative and related employees in other companies. Employees of all occupational groups of the hospital were often frustrated and felt their work was not appreciated. Frequent demands included improved work atmosphere, better appreciation of work and better information regarding innovations. The analysis of standardized survey results specific for companies and occupational groups is an appropriate way to identify targets of health promotion. Constant over three surveys, again a high burden of stress was found in health care workers even affecting the administrative staff, regarding several work-related stress factors. According to our results activities to improve the working conditions in hospitals are urgently needed. © Georg Thieme Verlag KG Stuttgart · New York.

The purpose of this study is to survey and assess radioactive contamination of foodstuffs in order to reduce the probability of intake of contaminated foodstuffs. Based on survey and assessment, final goal is to improve the public health by radiation protection. Sampled foodstuffs items are collected from the markets : one group are imported foodstuffs and the other group are domestic foodstuffs producted around nuclear facilities. After pretreatments such as drying, ashing, and homogenization, all samples were analyzed by gamma spectrometer system. The {sup 137}Cs radionuclide was only measured among the regulation radionuclides ({sup 137}Cs, {sup 134}Cs, {sup 131}I) of food code. All radionuclides of the domestic foodstuffs collected around nuclear facilities were below Minimum Detectable Activity (MDA). But the activity concentrations of Inonotus obliquus (Chaga mushooms) from Russia ranged up to 171.27 (average value : 36.65) Bq/kg-fresh. In the case of blueberry jam, the radioactivity of {sup 137}Cs is higher than expected value. Other samples are below MDA except some spices. Based on the previous and present results, it should be strengthen to survey for Inontus obliquus (Chaga mushooms), of which the radioactivity shows the range from MDA up to 800.01 Bq/kg-fresh. It should assess the public radiation exposure via food chain because it has the excess provability of the maximum permitted level of food code, which is regulation of KFDA. The development method based on international standard would be used at radioactive analysis as well as education of practical workers and it could be applied as the basis data for amending the analysis method of food code. Our country only surveys gamma emitting radionuclides till now but international organization or foreign countries for example EU survey alpha and beta emitting radionuclides as well as gamma emitting radionuclides. So our country should also research necessity of survey for alpha and beta emitting

Given the rising prevalence of obesity in the United States, innovative methods are needed to increase physical activity (PA) in community settings. Evidence suggests that individuals are more likely to engage in PA if they are given a choice of activities and have support from others (for encouragement, motivation, and accountability). The objective of this study was to describe the use of the online Walk Georgia PA tracking platform according to whether the user was an individual user or group user. Walk Georgia is a free, interactive online tracking platform that enables users to log PA by duration, activity, and perceived difficulty, and then converts these data into points based on metabolic equivalents. Users join individually or in groups and are encouraged to set weekly PA goals. Data were examined for 6,639 users (65.8% were group users) over 28 months. We used independent sample t tests and Mann-Whitney U tests to compare means between individual and group users. Two linear regression models were fitted to identify factors associated with activity logging. Users logged 218,766 activities (15,119,249 minutes of PA spanning 592,714 miles [41,858,446 points]). On average, group users had created accounts more recently than individual users (P < .001); however, group users logged more activities (P < .001). On average, group users logged more minutes of PA (P < .001) and earned more points (P < .001). Being in a group was associated with a larger proportion of weeks in which 150 minutes or more of weekly PA was logged (B = 20.47, P < .001). Use of Walk Georgia was significantly higher among group users than among individual users. To expand use and dissemination of online tracking of PA, programs should target naturally occurring groups (eg, workplaces, schools, faith-based groups).

To examine trends in leisure time physical activity and inactivity in Australians aged 15 years or older from 1989 to 2011. We used data from six Australian National Health Surveys conducted from 1989/90 to 2011/12 in which physical activity was assessed using comparable questions. Analyses examined trends in the prevalence of sufficient physical activity (≥150 minutes/week moderate-to-vigorous physical activity) and of inactivity (benefits from sufficient physical activity. Maintenance of consistent physical activity questions in future National Health Surveys will facilitate long term tracking of physical activity levels in the Australian population. © 2017 The Authors.

Recently, an international collaboration in securing and managing radioactive sources, particularly orphan sources, is established. For developing countries such as Indonesia which possesses relatively inadequate resources, an effective approach in dealing with the problem is crucial. In order to deal with this situation, an activity was performed including: 1) assessment of available technical means, 2) car-borne survey during the dry and rainy seasons to identify the impact of Rn daughter washout on the interpretation of search results, 3) search for anomalies in the radioactive exposure map of the Java island, and 4) investigation of anomalies found, using more sophisticated instrument, to detect and secure orphan and illicit radioactive sources. The performance of four selected instruments in a car-borne survey which covers a large area in western part of Java was evaluated. Data series of moving background were divided into two measurement groups; control group and test group. These data series were arranged in, order to determine the value of alarm level. For this purpose, statistic procedures relying on Mann-Whitney U test and a simple moving average test (Moving Background) were applied. Among the four selected survey meters, the most convenient detection system for implementing the activity is Exploranium GR-130. There was little concern on the effect of Rn-daughters washouts on the proposed methods, provided that the operator could recognise the transition period between the clear and rainy weather as it could give rise to false alarm. The Moving Background method was generally superior to Mann-Whitney U test for detecting anomalous radiation level. During the survey, an anomaly in steel industrial area was detected. Using portable gamma spectrometers, it was concluded that the anomaly was generated from naturally occurring radioactive materials (NORM). Analyses upon survey data in the big cities showed anomalies due to concrete structures, especially

Augmentation mammoplasty is one of the most common esthetic procedures worldwide. A wide range of motivations leads women to undergo this procedure, among them socioeconomic status and age group. The aim of this study was to identify the motivation spectrum for augmentation mammoplasty through different age groups. We conducted a cross-sectional prospective survey given to Israeli women seeking augmentation mammoplasty consults in a hospital and private clinic settings, using a 17-item Motivation for Augmentation questionnaire. Three motivation domains were examined: appearance, sexuality and social. Study participants were divided into three age groups: 18-29, 30-39 and over 40 years. A total of 101 women participated in the study. Motivations were rated similar among all age groups. Appearance and sexuality domains were rated significantly higher compared with the social domain throughout all age groups (3.28 ± 0.91 and 3.15 ± 1.03 vs. 1.88 ± 1.16, p age. The desire to improve one's appearance and sexuality is more prominent than improving social and work status. This journal requires that authors assign a level of evidence to each article.

Health literacy is of increasing importance in public health research. It is a necessary pre-condition for the involvement in decisions about health and health care and related to health outcomes. Knowledge about limited health literacy in different age groups is crucial to better target public health interventions for subgroups of the population. However, little is known about health literacy in Germany. The study therefore assesses the prevalence of limited health literacy and associated factors among different age groups. The Health Literacy Survey Germany is a cross-sectional study with 2,000 participants aged 15 years or older in private households. Perceived health literacy was assessed via computer-assisted personal interviews using the HLS-EU-Q-47 questionnaire. Descriptive analyses, chi-square tests and odds ratios were performed stratified for different age groups. The population affected by limited perceived health literacy increases by age. Of the respondents aged 15-29 years, 47.3 % had limited perceived health literacy and 47.2 % of those aged 30-45 years, whereas 55.2 % of the respondents aged 46-64 years and 66.4 % aged 65 years and older showed limited perceived health literacy. In all age groups, limited perceived health literacy was associated with limited functional health literacy, low social status, and a high frequency of doctor visits. The results suggest a need to further investigate perceived health literacy in all phases of the life-course. Particular attention should be devoted to persons with lower social status, limited functional health literacy and/or a high number of doctor visits in all age groups.

Physical inactivity presents a major public health challenge and is estimated to cause six to ten percent of the major non-communicable diseases. Studies show that immigrants, especially women, have an increased risk of non-communicable diseases compared to ethnic Swedes. Somali immigrant women have increased rates of overweight and obesity, low fitness levels and low levels of cardiorespiratory fitness compared to non-immigrant women. These findings suggest that Somali women are at increased risk of developing lifestyle-related diseases. Few studies explore determinants of physical activity among Somali women. The aim of this study was to explore Somali women's views and experiences of physical activity after migration to Sweden. A qualitative focused ethnographic approach was used in this study. Four focus groups were conducted with twenty-six Somali women ranging from 17 to 67 years of age. Focus group discussions were recorded, transcribed verbatim and analysed using qualitative content analysis. The analysis resulted in four main themes and ten categories: Life in Somalia and Life in Sweden, Understanding and enhancing health and Facilitators and barriers to physical activity. Great differences were seen between living in Somalia and in Sweden but also similarities such as finding time to manage housework, the family and the health of the woman. The extended family is non-existent in Sweden, making life more difficult. Health was considered a gift from God but living a healthy life was perceived as the responsibility of the individual. Misconceptions about enhancing health occurred depending on the woman's previous life experience and traditions. There was an awareness of the importance of physical activity among the participants but lack of knowledge of how to enhance activity on an individual basis. Enhancing factors to an active lifestyle were identified as being a safe and comfortable environment. Some barriers, such as climate, lack of motivation and time

Full Text Available In order to improve sorption properties of activated carbon cloth that can be used for wastewater purification, mechanochemical activation was performed in both inert and air atmosphere. Boehm method was used to follow the changes in the number and types of surface groups induced by mechanical milling. The number of the base groups of 0,2493 mmol/g is significantly smaller than the total amount of acidic functional groups, 2,5093 mmol/g. Among the acidic groups present on the surface, the most represented are phenolic groups (2.3846 mmol/g , ie . > 95 % , the carboxylic groups are present far less (0.1173 mmol /g, ie. 4.5 %, while the presence of the lactone group on the surface of ACC is negligible (0.0074 mmol/g ie. under 0.3 %. Mechanochemical activation lead to an increase in the number of acidic and basic groups on the surface of the ACC. The milling in inert atmosphere has dominant effect with respect to the changes in the total number of basic functional groups (compared to milling in an air atmosphere: the number of basic groups of the ACC was 0.8153 mmol/g milled under argon, 0.7933 mmol/g in the air; the number of acidic groups is 2.9807 mmol/g for a sample milled under argon and 3.5313 mmol/g for one milled in the air.

Variations between countries in leisure-time physical activity (LTPA) can be used to test the convergence thesis, which expects that ethnic minority groups change towards the LTPA levels of the native population of host countries. The aim of this study was to test whether similar differences in LTPA between the native populations of England and the Netherlands are also observed among the Indian and African descent groups living in these countries. We used English and Dutch population-based health surveys that included participants aged 35-60 years of European (n(english) = 14,723, n(dutch) = 567), Indian (n(english) = 1264, n(dutch) = 370) and African-Caribbean (n(english) = 1112, n(dutch) = 689) descent. Levels of LTPA (30-minute walking, any reported cycling, gardening, dancing and playing sports) were estimated with age-sex-standardized prevalence rates. Comparisons among groups were made using adjusted Prevalence Ratios (PRs). Within both countries and compared with the European group, Indian and African groups had lower levels of gardening and cycling, whereas the African groups had higher levels of dancing. Between countries, among the European groups, the Netherlands showed higher prevalence of cycling than England, PR = 2.26 (95% CI: 2.06-2.48), and this was 2.85 (1.94-4.19) among Indian descent, and 2.77 (2.05-3.73) among African descent. For playing sports, this was PR = 1.30 (1.23-1.38), 1.43 (1.24-1.66) and 1.22 (1.10-1.34), whereas for gardening this was PR = 0.71 (0.65-0.78), 0.65 (0.52-0.81) and 0.75 (0.62-0.90), respectively. Walking and dancing showed inconsistent differences between the countries and ethnic groups. This cross-national comparison supports the expectation that LTPA of Indian and African descent groups converge towards the national levels of England and the Netherlands respectively.

Many children, in particular girls, do not reach the recommended amount of daily physical activity. School recess provides an opportunity for both boys and girls to be physically active, but barriers to recess physical activity are not well understood. This study explores gender differences in children's perceptions of barriers to recess physical activity. Based on the socio-ecological model four types of environmental barriers were distinguished: natural, social, physical and organizational environment. Data were collected through 17 focus groups (at 17 different schools) with in total 111 children (53 boys) from fourth grade, with a mean age of 10.4 years. The focus groups included an open group discussion, go-along group interviews, and a gender segregated post-it note activity. A content analysis of the post-it notes was used to rank the children's perceived barriers. This was verified by a thematic analysis of transcripts from the open discussions and go-along interviews. The most frequently identified barriers for both boys and girls were weather, conflicts, lack of space, lack of play facilities and a newly-found barrier, use of electronic devices. While boys and girls identified the same barriers, there were both inter- and intra-gender differences in the perception of these barriers. Weather was a barrier for all children, apart from the most active boys. Conflicts were perceived as a barrier particularly by those boys who played ballgames. Girls said they would like to have more secluded areas added to the school playground, even in large schoolyards where lack of space was not a barrier. This aligned with girls' requests for more "hanging-out" facilities, whereas boys primarily wanted activity promoting facilities. Based on the results from this study, we recommend promoting recess physical activity through a combination of actions, addressing barriers within the natural, social, physical and organizational environment.

Acculturation to U.S. society has been associated with an increase in drinking and binge drinking among Hispanics. This paper examines the association between acculturation and three drinking-related outcomes: average number of drinks consumed, binge drinking, and drinking 12 drinks or more in a single day in four major Hispanic national groups. The 2006 Hispanic Americans Baseline Alcohol Survey used a multistage cluster sample design to interview 5224 adult Hispanics (18+ years) in five selected U.S. metropolitan areas: Miami, New York, Philadelphia, Houston, and Los Angeles. The four national groups interviewed were: Puerto Ricans, Cuban Americans, Mexican Americans, and South/Central Americans. The survey response rate was 76%. Data on drinking behavior were collected and the analyses include bivariate and multivariate regression techniques. Multivariate analysis did not show an association between acculturation and volume of drinking, binge drinking, or drinking 12 or more drinks in a single day among men. Acculturation stress, however, was associated with drinking 12 or more in a day among men. Among women, high acculturation was associated with a higher volume of drinking, and it also interacted with national group to increase the likelihood of binge drinking. Acculturation does not have a homogeneous effect on drinking across gender and Hispanic national groups. The results confirm that acculturation has a more consistent association with increased drinking and binge drinking among women than among men. The effect of acculturation is therefore gender-specific. This heterogeneity across Hispanic national groups must be considered in future research, treatment, and prevention efforts.

Music therapists have access to a rapidly expanding body of research supporting the use of music-based interventions. What is not known is the extent to which music therapists access these resources and what factors may prevent them from incorporating research findings into clinical work. After constructing the Music Therapists' Research Activity and Utilization Barrier (MTRAUB) database, the purposes of this study involved: assessing the extent to which American Music Therapy Association (AMTA) members engage in certain research-related activities; and identifying respondents' perceived barriers to integrating research into clinical practice. This study employed a quantitative, non-experimental approach using an online survey. Respondents included professional, associate, student/graduate student, retired, inactive, and honorary life members of AMTA. Instrumentation involved a researcher-designed Background Questionnaire as well as the Barriers to Research Utilization Scale (BARRIERS; Funk, Champagne, Wiese, & Tornquist, 1991), a tool designed to assess perceived barriers to incorporating research into practice. Of the 3,194 survey invitations distributed, 974 AMTA members replied (a response rate of 30%). Regarding research-related activities, descriptive findings indicate that journal reading is the most frequently reported research-related activity while conducting research is the least frequently reported activity. Results from the BARRIERS Scale indicated that Organizational and Communication factors are perceived as interfering most prominently with the ability to utilize research in clinical practice. Findings suggest that research-related activity and perceived barriers vary as a function of educational attainment, work setting, and occupational role. The author discusses these differential findings in detail, suggests supportive mechanisms to encourage increased research activity and utilization, and offers recommendations for further analysis of the

Multi-group transport methods for high-resolution neutron activation analysis

International Nuclear Information System (INIS)

The accurate and efficient simulation of coupled neutron-photon problems is necessary for several important radiation detection applications. Examples include the detection of nuclear threats concealed in cargo containers and prompt gamma neutron activation analysis for nondestructive determination of elemental composition of unknown samples. In these applications, high-resolution gamma-ray spectrometers are used to preserve as much information as possible about the emitted photon flux, which consists of both continuum and characteristic gamma rays with discrete energies. Monte Carlo transport is the most commonly used modeling tool for this type of problem, but computational times for many problems can be prohibitive. This work explores the use of multi-group deterministic methods for the simulation of neutron activation problems. Central to this work is the development of a method for generating multi-group neutron-photon cross-sections in a way that separates the discrete and continuum photon emissions so that the key signatures in neutron activation analysis (i.e., the characteristic line energies) are preserved. The mechanics of the cross-section preparation method are described and contrasted with standard neutron-gamma cross-section sets. These custom cross-sections are then applied to several benchmark problems. Multi-group results for neutron and photon flux are compared to MCNP results. Finally, calculated responses of high-resolution spectrometers are compared. Preliminary findings show promising results when compared to MCNP. A detailed discussion of the potential benefits and shortcomings of the multi-group-based approach, in terms of accuracy, and computational efficiency, is provided. (authors)

A Test of the Active-Day Fraction Method of Sunspot Group Number Calibration: Dependence on the Level of Solar Activity

Science.gov (United States)

Willamo, T.; Usoskin, I. G.; Kovaltsov, G. A.

2018-04-01

The method of active-day fraction (ADF) was proposed recently to calibrate different solar observers to standard observational conditions. The result of the calibration may depend on the overall level of solar activity during the observational period. This dependency is studied quantitatively using data of the Royal Greenwich Observatory by formally calibrating synthetic pseudo-observers to the full reference dataset. It is shown that the sunspot group number is precisely estimated by the ADF method for periods of moderate activity, may be slightly underestimated by 0.5 - 1.5 groups ({≤} 10%) for strong and very strong activity, and is strongly overestimated by up to 2.5 groups ({≤} 30%) for weak-to-moderate activity. The ADF method becomes inapplicable for the periods of grand minima of activity. In general, the ADF method tends to overestimate the overall level of activity and to reduce the long-term trends.

A clutch of young chicks housed with a mother hen exhibit ultradian (within day) rhythms of activity corresponding to the brooding cycle of the hen. In the present study clear evidence was found of ultradian activity rhythms in newly hatched domestic chicks housed in groups larger than natural clutch size without a mother hen or any other obvious external time-keeper. No consistent synchrony was found between groups housed in different pens within the same room. The ultradian rhythms disappeared with time and little evidence of group rhythmicity remained by the third night. This disappearance over time suggests that the presence of a mother hen may be pivotal for the long-term maintenance of these rhythms. The ultradian rhythm of the chicks may also play an important role in the initiation of brooding cycles during the behavioural transition of the mother hen from incubation to brooding. Computer simulations of individual activity rhythms were found to reproduce the observations made on a group basis. This was achievable even when individual chick rhythms were modelled as independent of each other, thus no assumptions of social facilitation are necessary to obtain ultradian activity rhythms on a group level.

Purpose: AAPM Task Group (TG) 275 is charged with developing riskbased guidelines for plan and chart review clinical processes. As part of this work an AAPM-wide survey was conducted to gauge current practices. Methods: The survey consisted of 103 multiple-choice questions covering the following review processes for external beam including protons: 1) Initial Plan Check, 2) On-Treatment and 3) End-of-Treatment Chart Check. The survey was designed and validated by TG members with the goal of providing an efficient and easy response process. The survey, developed and deployed with the support of AAPM headquarters, was released to all AAPM members who have self-reported as working in the radiation oncology field and it was kept open for 7 weeks. Results: There are an estimated 4700 eligible participants. At the time of writing, 962 completed surveys have been collected with an average completion time of 24 minutes. Participants are mainly from community hospitals (40%), academicaffiliated hospitals (31%) and free-standing clinics (18%). Among many other metrics covered on the survey, results so far indicate that manual review is an important component on the plan and chart review process (>90%) and that written procedures and checklists are widely used (>60%). However, the details of what is reviewed or checked are fairly heterogeneous among the sampled medical physics community. Conclusion: The data gathered from the survey gauging current practices will be used by TG 275 to develop benchmarks and recommendations for the type and extent of checks to perform effective physics plan and chart review processes.

In 2011, the Australian Commission on Safety and Quality in Health Care (ACSQHC) recommended that all hospitals in Australia must have an Antimicrobial Stewardship (AMS) program by 2013. Nevertheless, little is known about current AMS activities. This study aimed to determine the AMS activities currently undertaken, and to identify gaps, barriers to implementation and opportunities for improvement in Queensland hospitals. The AMS activities of 26 facilities from 15 hospital and health services in Queensland were surveyed during June 2012 to address strategies for effective AMS: implementing clinical guidelines, formulary restriction, reviewing antimicrobial prescribing, auditing antimicrobial use and selective reporting of susceptibility results. The response rate was 62%. Nineteen percent had an AMS team (a dedicated multidisciplinary team consisting of a medically trained staff member and a pharmacist). All facilities had access to an electronic version of Therapeutic Guidelines: Antibiotic, with a further 50% developing local guidelines for antimicrobials. One-third of facilities had additional restrictions. Eighty-eight percent had advice for restricted antimicrobials from in-house infectious disease physicians or clinical microbiologists. Antimicrobials were monitored with feedback given to prescribers at point of care by 76% of facilities. Deficiencies reported as barriers to establishing AMS programs included: pharmacy resources, financial support by hospital management, and training and education in antimicrobial use. Several areas for improvement were identified: reviewing antimicrobial prescribing with feedback to the prescriber, auditing, and training and education in antimicrobial use. There also appears to be a lack of resources to support AMS programs in some facilities. WHAT IS KNOWN ABOUT THE TOPIC?: The ACSQHC has recommended that all hospitals implement an AMS program by 2013 as a requirement of Standard 3 (Preventing and Controlling Healthcare

Full Text Available Abstract Background Abundant literature supports the beneficial effects of physical activity for improving health of people with chronic diseases. The relationship between multimorbidity and physical activity levels, however, has been little evaluated. The purpose of the current exploratory study was to examine the relationship between a multimorbidity and physical activity levels, and b long-term limitations on activity, self-rated general health, psychological distress, and physical activity levels for each sex in adults, after age, education, income, and employment factors were controlled for. Methods Data from the Quebec Health Survey 1998 were used. The sample included 16,782 adults 18–69 yr of age. Independent variables were multimorbidity, long-term limitations on activity, self-rated general health, and psychological distress. The dependent variable was physical activity levels. Links between the independent and dependent variables were assessed separately for men and women with multinomial regressions while accounting for the survey sampling design and household clustering. Results About 46% of the participants were men. Multimorbidity was not associated with physical activity levels for either men or women. Men and women with long-term limitations on activity and with poor-to-average self-rated general health were less likely to be physically active. No relationship between psychological distress and physical activity was found for men. Women with high levels of psychological distress were less likely to be physically active. Conclusion Multimorbidity was not associated with physical activity levels in either sex, when age, education, income, and employment factors were controlled for. Long-term limitations on activity and poor-to-average self-rated general health seem related to a reduction in physical activity levels for both sexes, whereas psychological distress was associated with a reduction in physical activity levels only

Older Hispanic Americans are a rapidly growing minority group who are disproportionately affected by diabetes mellitus and obesity. Given the importance of physical activity, particularly leisure-time activity, in the management of diabetes mellitus and obesity, the current study examined ethnic and sex differences in walking for transportation, leisure-time walking, moderate activity (not including walking), and vigorous activity between Hispanic and non-Hispanic white (NHW) older adults (age 55 and older) using the 2009 California Health Interview Survey, a population-based survey representative of California's noninstitutionalized population. The total sample consisted of 21,702 participants (20,148 NHW (7,968 men, 12,180 women) and 1,554 Hispanic (609 men, 945 women)). Multivariable logistic and linear regression analyses were adjusted for sociodemographic characteristics. The findings revealed that Hispanic men and women were significantly less likely to engage in self-reported leisure-time walking and vigorous activity than NHW men (adjusted odds ratio (aOR) = 0.71, 95% confidence interval (CI) = 0.51-0.99) and women (aOR = 0.60, 95% CI = 0.42-0.87). Regardless of ethnic group, men were more likely than women to engage in self-reported walking for transportation (aOR = 0.71, 95% CI = 0.58-0.87), moderate activity (aOR = 0.68, 95% CI = 0.57-0.81), and vigorous activity (aOR = 0.58, 95% CI = 0.50-0.68). All types of self-reported physical activity were associated with lower body mass index (BMI; P activity (P activity (P activities reported the lowest BMIs. The findings highlight the importance of emphasizing walking in efforts to increase moderate and vigorous activity, particularly for older women. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

The purpose of this study was to compare the results from a survey of Omaha worksite health promotion activities with the results of a 1992 national survey. Comparisons were made on: (1) the kinds of health promotion activities offered, (2) progress toward the Healthy People 2000 worksite objectives, (3) types of program intervention offered, and (4) administrative factors. A one-time, written, mail-out/mail-back survey design was used. The study took place in Omaha, Nebraska. All area public and private worksites with 250 or more employees were sent surveys. Individuals who were preselected and identified as the best qualified within the company completed the survey instrument. Of the 176 worksites surveyed, 86 completed the survey (49%). Descriptive statistics (percentages) were used to compare the two surveys on kinds of programs offered, progress toward Healthy People 2000 related to worksite health promotion, the types of program intervention offered, and administrative factors. Generally, a greater percentage of respondent worksites from the national survey are offering more health promotion activities and have made more progress toward the Healthy People 2000 worksite objectives than the Omaha worksites. Results from both surveys showed that low levels of intervention are more prevalent than high levels of intervention, and that health promotion activities in most worksites are coordinated by human resources departments and not by someone professionally prepared in health education. Traditionally, major goals of worksite health promotion programs have focused on important organizational outcomes such as improved productivity/morale, reduction in absenteeism, and health care cost-containment. It is important to recognize, however, that low levels of intervention have less impact than more intensive programs on these desired outcomes. Future goals for local and national worksite health promotion programs may need to encourage implementation of more intensive

1982-06-01

In 1979 a working group on neutron radiography was formed at Euratom. The purpose of this group is the standardization of neutron radiographic methods in the field of nuclear fuel. Activities of this Neutron Radiography Working Group are revised. Classification of defects revealed by neutron radiography is illustrated in a special atlas. Beam purity and sensitivity indicators are tested together with a special calibration fuel pin. All the Euratom neutron radiography centers will perform comparative neutron radiography with those items. The measuring results obtained, using various measuring aparatus will form the basis to formulate conclusions about the best measuring methods and instruments to be used in that field. Besides the atlas of neutron radiographic findings in light water reactor fuel, the Euratom Neutron Radiogrphy Working Group has published a neutron radiography handbook in which the neutron radiography installations in the European Community are also described.

This study was conducted to evaluate students' experiences in a psychiatric and mental health nursing course using psychosocial group activities to develop therapeutic communication and interpersonal relationship skills, as well as to introduce psychosocial nursing interventions. A qualitative research design was used. The study explored nursing students' experiences of the course in accordance with the inductive, interpretative, and constructive approaches via focus group interviews. Participants were 17 undergraduate nursing students who registered for a psychiatric and mental health nursing course. The collected data were analyzed by qualitative content analysis. The analysis resulted in 28 codes, 14 interpretive codes, 4 themes (developing interpersonal relationships, learning problem-solving skills, practicing cooperation and altruism, and getting insight and healing), and a core theme (interdependent growth in self-confidence). The psychosocial group activity provided constructive opportunities for the students to work independently and interdependently as healthcare team members through reflective learning experiences.

2002-01-01

During the early stages of the ISAM project confidence building was a relatively new topic in the radioactive waste disposal literature, but it was beginning to receive some attention. Although almost all safety assessment activities are intended to provide a level of confidence in the results of the assessment, considering the activities from the viewpoint of how they contributed to the decision making of various 'audiences' was relatively new. The ISAM project included the Confidence Building Working Group (CBWG) to examine the topic of Confidence Building and this paper provides a summary of the working group findings. (author)

Type 2 diabetes mellitus (T2DM) is the most common form of diabetes. Risk factors for its development include older age, obesity, family history of diabetes, history of gestational diabetes, impaired glucose metabolism, physical inactivity, and race/ethnicity. The purpose of this study was to characterize T2DM burden, from a patient perspective, with respect to age and race/ethnicity. Adults aged ≥18 years with T2DM from a large, Internet-based, nationwide survey were retrospectively analyzed. Demographic and clinical characteristics (glycemic control, body mass index [BMI], comorbidities, and diabetes-related complications), hypoglycemic episodes, and medication adherence were used to assess diabetes burden. Degree of burden was compared across age (18-64, 65-74, and ≥75 years) and racial/ethnic (white, African American, Hispanic, Asian, and American Indian) groups. An apparent association was found between glycemic control and medication adherence. Hispanics had the lowest percentage of participants with a hemoglobin A1c (HbA1c) level groups. Conversely, American Indians and whites had the best glycemic control, HbA1c knowledge, and medication adherence. The 18- to 64-year age group had the poorest glycemic control (28.8%), the most with unknown HbA1c levels (46.3%), and the poorest medication adherence of the age groups. Mean BMIs were high (>30 mg/kg(2)) for all racial/ethnic groups other than the Asian group (28.9 mg/kg(2)). Approximately 71% of Asians were obese or overweight compared with ≥90% in the other racial/ethnic groups. Mean BMIs decreased with increasing age group (34.5, 32.6, and 29.8 kg/m(2) for the age groups of 18-64, 65-74, and ≥75 years, respectively). Regarding diabetes-related comorbidities, the Asian group had the lowest percentages of those with hypertension (39.1%) and hypercholesterolemia (46.6%). The Asian group had the lowest mean Charlson Comorbidity Index (CCI) score (score of 1.4); the American Indian group had the highest

To describe objectively determined sedentary and activity outcomes (volume and pattern) and their associations with cardiometabolic risk biomarkers in individuals with and without mobility disability. Cross-sectional. Population based. Community-dwelling older adults (≥60) living in the United States who were participants in the 2003 to 2004 or 2005 to 2006 National Health and Nutrition Examination Survey. Participants were classified as with or without mobility disability according to responses to self-reported questions about ability to walk, climb stairs, and/or use of ambulatory aids. Accelerometer-derived sedentary and activity variables for volume (time in sedentary (activity and pattern (number of breaks from sedentary time, duration of sedentary bouts, duration of activity bouts). Survey-weighted regression models, adjusted for age, sex, ethnicity, education, and smoking, were used to examine the associations between pattern of activity and cardiometabolic health risk factors (blood pressure, waist circumference, high-density lipoprotein cholesterol). Of the 2,017 participants, 547 were classified as having a mobility disability. Participants with mobility disability had more sedentary time and less active time than those without. Sedentary bouts were longer and active bouts shorter in those with disability. The total number of sedentary breaks (transitions from sedentary to nonsedentary) differed between groups after adjustment for total sedentary time. Fewer breaks, longer sedentary bouts, and shorter activity bouts were associated with higher average waist circumference regardless of disability status. This study provides rationale for the development and testing of interventions to change the pattern of activity (e.g., include more breaks and longer activity bout durations) in older adults with mobility disability. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

The paper describes technical and functional surveys on COM buildings (Mixed Operative Centre). This activity started since 2005, with the contribution of both Italian Civil Protection Department and the Regions involved. The project aims to evaluate the efficiency of COM buildings, checking not only structural, architectonic and functional characteristics but also paying attention to surrounding real estate vulnerability, road network, railways, harbours, airports, area morphological and hydro-geological characteristics, hazardous activities, etc. The first survey was performed in eastern Sicily, before the European Civil Protection Exercise ''EUROSOT 2005''. Then, since 2006, a new survey campaign started in Abruzzo, Molise, Calabria and Puglia Regions. The more important issue of the activity was the vulnerability assessment. So this paper deals with a more refined vulnerability evaluation technique by means of the SAVE methodology, developed in the 1st task of SAVE project within the GNDT-DPC programme 2000-2002 (Zuccaro, 2005); the SAVE methodology has been already successfully employed in previous studies (i.e. school buildings intervention programme at national scale; list of strategic public buildings in Campania, Sicilia and Basilicata). In this paper, data elaborated by SAVE methodology are compared with expert evaluations derived from the direct inspections on COM buildings. This represents a useful exercise for the improvement either of the survey forms or of the methodology for the quick assessment of the vulnerability

Instrumental neutron activation analysis (NAA) technique was used to analyze stream sediments collected in Northwestern Mindoro. The concentration levels of 18 elements were determined. It was noted that NAA is suitable for the determination of rare earth, gold, arsenic and cobalt among others because of favorable high neutron cross sections. Samples collected in regional reconnaissance geochemical surveys could be analyzed usng NAA technique to complement other non-nuclear techniques, such as atomic absorption and X-ray fluorescence analysis.

A North Japan Radiation Oncology Group (NJRTOG) survey was carried out to disclose the risk management of radiation therapy. During April 2002, we sent questionnaires to radiation therapy facilities in northern Japan. There were 31 replies from 27 facilities. Many incidents and accidents were reported, including old cases. Although 60% of facilities had a risk management manual and/or risk manager, only 20% had risk management manuals for radiation therapy. Eighty five percent of radiation oncologists thought that incidents may be due to a lack of manpower. Ninety percent of radiation oncologists want to know the type of cases happened in other facilities. The risk management system is still insufficient for radiation therapy. We hope that our data will be a great help to develop risk management strategies for radiation therapy for all radiation oncologists in Japan. (author)

Amjad Mehmood

2018-06-01

Full Text Available Although wireless sensor networks (WSNs have been the object of research focus for the past two decades, fault diagnosis in these networks has received little attention. This is an essential requirement for wireless networks, especially in WSNs, because of their ad-hoc nature, deployment requirements and resource limitations. Therefore, in this paper we survey fault diagnosis from the perspective of network operations. To the best of our knowledge, this is the first survey from such a perspective. We survey the proactive, active and passive fault diagnosis schemes that have appeared in the literature to date, accenting their advantages and limitations of each scheme. In addition to illuminating the details of past efforts, this survey also reveals new research challenges and strengthens our understanding of the field of fault diagnosis.

2006-08-01

Full Text Available Abstract Background When examining the prevalence of physical inactivity by gender and age, women over the age of 25 are at an increased risk for sedentary behavior. Childbearing and motherhood have been explored as one possible explanation for this increased risk. Post natal exercise studies to date demonstrate promising physical and psychological outcomes, however few physical activity interventions have been theory-driven and tailored to post natal exercise initiates. The purpose of this study was to compare the effects of a group-mediated cognitive behavioral intervention based upon social-cognitive theory and group dynamics (GMCB to a standard care postnatal exercise program (SE. Method A randomized, two-arm intervention design was used. Fifty-seven post natal women were randomized to one of two conditions: (1 a standard exercise treatment (SE and (2 a standard exercise treatment plus group-mediated cognitive behavioral intervention (GMCB. Participants in both conditions participated in a four-week intensive phase where participants received standard exercise training. In addition, GMCB participants received self-regulatory behavioral skills training via six group-mediated counseling sessions. Following the intensive phase, participants engaged in a four-week home-based phase of self-structured exercise. Measures of physical activity, barrier efficacy, and proximal outcome expectations were administered and data were analyzed using ANCOVA procedures. Results and discussion ANCOVA of change scores for frequency, minutes, and volume of physical activity revealed significant treatment effects over the intensive and home-based phases (p's Conclusion While both exercise programs resulted in improvements to exercise participation, the GMCB intervention produced greater improvement in overall physical activity, barrier efficacy and proximal outcome expectations.

Medical Students' Empathy for Vulnerable Groups: Results From a Survey and Reflective Writing Assignment.

2017-12-01

As medical education curricula increasingly acknowledge the contributions of the social determinants of health to individual health, new methods of engaging students in the care of vulnerable groups are needed. Empathy is one way to connect students with patients, but little is known about how to nurture students' empathy on behalf of populations. This study examined the relationship between individual and social empathy as groundwork for cultivating students' empathy for vulnerable groups. In 2014-2015, first-year medical students completed the Social Empathy Index at the start and end of a two-semester population health course, and they completed a reflective writing assignment exploring the challenges of caring for vulnerable patients. Pre- and posttest mean survey scores were compared, and reflective writing assignments were analyzed for themes concerning social empathy. Data from 130 students were analyzed. Scores for the contextual understanding of systemic barriers domain increased significantly. There was a trend toward increased cumulative social empathy scores that did not reach statistical significance. Students' essays revealed three themes relating to individual empathy as the foundation for social empathy; civic and moral obligations; and the role of institutional practices in caring for vulnerable groups. This study extends understanding of empathy beyond care for the individual to include care for vulnerable groups. Thus, social empathy may function as a valuable concept in developing curricula to support students' commitment to care for the underserved. Educators first need to address the many barriers students cited that impede both individual and social empathy.

Regional and Detailed Survey for Radon Activities in Soil-Gas and Groundwater in the Okchon Zone, Korea

Science.gov (United States)

Je, H.-K.; Chon, H.-T.

2012-04-01

The Okchon zone in Korea provides a typical example of natural geological materials enriched in potentially toxic elements including uranium which is parent nuclide for radon gas. For the purpose of radon radioactivity risk assessment, making the map of radon risk grade from Okchon zone, regional and detailed field surveys were carried out during 3 years. The study area is located in the central part of Korea, called the Okchon zone (about 5,100 km2), which occur in a 80km wide, northeast-trending belt that extends across the Korean Peninsula. The Okchon zone is underlain by metasedimentary rocks of unknown age that are composed mainly of black slate, phyllite, shale, and limestone. The three research areas (defined as Boeun, Chungju, and Nonsan) for detailed survey were selected from the results of regional survey. Results of detailed radon survey indicated a wide range of radon activities for soil-gases (148-1,843 pCi/L) and ground waters (23-5,540 pCi/L). About 15 percent of soil-gas samples exceeded 1,000 pCi/L and 84 percent of ground water samples exceeded the MCL (maximum contaminant level) of drinking water, 300 pCi/L, which proposed by U.S. Environmental Protection Agency in 1999. For detailed survey, radon activities of soil-gas and ground water were classified as bedrock geology, based on 1/50,000 geological map and field research. For soil-gas measurements, mean values of radon activity from black slate-shale (789 pCi/L) were highest among the other base rocks. And for groundwater measurements, mean value of radon activities were decreased in the order of granite (1,345 pCi/L) > black shale-slate (915 pCi/L) > metasediments (617 pCi/L). Result of indoor radon measurement from detailed survey areas showed that about 50% of houses exceeded the indoor guideline, 4 pCi/L. For the radon risk assessment in indoor environment showed that probability of lung cancer risk from the houses located on the granite base rock (3.0×10-2) was highest among the other

Activities of radiopharmaceuticals administered for diagnostic and therapeutic procedures in nuclear medicine in Argentina: results of a national survey

Bomben, Ana M.; Chiliutti, Claudia A.

2004-01-01

Nuclear medicine in Argentine is carried out at 292 centres, distributed all over the country, mainly concentrated in the capital cities of the provinces. With the purpose of knowing the activity levels of radiopharmaceuticals that were administered to patients for diagnostic and therapeutic procedures in nuclear medicine, a national survey was conducted, during 2001 and 2002. This survey was answered voluntarily by 107 centres. Sixty-four percent of the participants centres are equipped with SPECT system while the other centres have a gamma camera or scintiscanner. There were 37 nuclear medicine procedures, chosen among those most frequently performed, were included in the survey. In those diagnostic procedures were included tests for: bone, brain, thyroid, kidney, liver, lung and cardiovascular system; and also activities administered for some therapeutic procedures. The nuclear medicine physicians reported the different radiopharmaceutical activities administered to typical adult patients. In this paper are presented the average radiopharmaceutical activity administered for each of the diagnostic and therapeutic procedures included in the survey and the range and distribution of values. In order to place these data in a frame of reference, these average values were compared to the guidance levels for diagnostic procedures in nuclear medicine mentioned at the Safety Series no. 115. From this comparison it was noticed that the activities administered in the 40% of the diagnostic procedures included in the survey were between ±30% of the reference values. For those nuclear medicine procedures that could not be compared with the above mentioned guidance levels, the comparison was made with values published by UNSCEAR or standards recommended by international bodies. As a result of this study, it is important to point out the need to continue the gathering of data in a wider scale survey to increase the knowledge about national trends. It is also essential to widely

An energy-dense, high-fat, low-fibre dietary pattern has been prospectively associated with the development of obesity in childhood but is population-specific, which limits translating the pattern into interventions. We explored the generalisability and correlates of this obesogenic dietary pattern in the UK National Diet and Nutrition Survey (NDNS) for the first time. Data came from participants ( n = 4636 children and n = 4738 adults) with 4-day food diaries in NDNS 2008-2014. Reduced rank regression was applied to 51 food groups to explain variation in energy density, fibre and fat intake. Consistency of the pattern in population subgroups (according to sex, age, occupation and income) was compared with the whole sample pattern using coefficients of congruence (COC). Pattern correlates (sociodemographic, survey year, physical activity and eating related behaviours) were explored using multiple linear regression. Food group loadings were similar to the previously identified obesogenic dietary pattern and were generalisable across all sub-groups (COC: 0.93-0.99). An obesogenic diet was associated with eating takeaways, being omnivorous, a manual household occupation and lower household income in both adults and children ( p pattern could be used to monitor the effectiveness of obesity prevention policies or develop personalised interventions.

Impact of postgraduate education on advanced practice nurse activity - a national survey.

2018-03-22

There is a wealth of international evidence concerning the contribution post-registration master's level education makes to advancing the discipline of nursing. There are approximately 277 nurse practitioners registered in NZ, but they account for only a small portion of nurses who have undertaken master's level education. The additional contribution these nurses make to the work environment through advanced practice activities has not, hitherto, been documented. To report the extent of advanced practice nurse activity associated with various levels of nursing education in a sample of nurses working in clinical practice in New Zealand. A replication of recent Australian research was done via a national cross-sectional survey of 3255 registered nurses and nurse practitioners in New Zealand using an online questionnaire to collect responses to the amended Advanced Practice Delineation survey tool. In addition, demographic data were collected including position titles and levels of postgraduate education. A positive association was found between postgraduate education at any level and more time spent in advanced practice activities. Independent of level of postgraduate education, the role a nurse holds also effects the extent of involvement in advanced practice activities. There is an additional contribution made to the work environment by nurses with master's level education which occurs even when they are not employed in an advanced practice role. These findings are of significance to workforce policy and planning across the globe as countries work to sustain health services by increasing nursing capacity effectively within available resources. © 2018 International Council of Nurses.

Major trunk trauma is common and costly, but comparisons of costs between trauma centers (TCs) are rare. Understanding cost is essential to improve quality, manage trauma service lines, and to facilitate institutional commitment for trauma. We have used results of a statewide trauma financial survey of Levels I to IV TC to develop a useful grouping method for costs and clinical characteristics of major trunk trauma. The trauma financial survey collected billing and clinical data on 75 per cent of the state trauma registry patients for fiscal year 2012. Cost was calculated by separately accounting for embedded costs of trauma response and verification, and then adjusting reasonable costs from the Medicare cost report for each TC. The cost-to-charge ratios were then recalculated and used to determine uniform cost estimates for each patient. From the 13,215 patients submitted for the survey, we selected 1,094 patients with major trunk trauma: lengths of stay ≥ 48 hours and a maximum injury of AIS ≥3 for either thorax or abdominal trauma. These patients were then divided into three Injury Severity Score (ISS) groups of 9 to 15, 16 to 24, or 25+ to stratify patients into similar injury groups for analysis of cost and cost drivers. For abdominal injury, average total cost for patients with ISS 9 to 15 was $17,429. Total cost and cost per day increased with severity of injury, with $51,585 being the total cost for those with ISS 25. Similar trends existed for thoracic injury. Use of the Medicare cost report and cost-to-charge ratios to compute uniform costs with an innovative grouping method applied to data collected across a statewide trauma system provides unique information regarding cost and outcomes, which affects quality improvement, trauma service line management, and decisions on TC participation.

Control of Surface Functional Groups on Pertechnetate Sorption on Activated Carbon

99 Tc is highly soluble and poorly adsorbed by natural materials under oxidizing conditions, thus being of particular concern for radioactive waste disposal. Activated carbon can potentially be used as an adsorbent for removing Tc from aqueous solutions. We have tested six commercial activated carbon materials for their capabilities for sorption of pertechnetate (TcO 4 - ). The tested materials can be grouped into two distinct types: Type I materials have high sorption capabilities with the distribution coefficients (K d ) varying from 9.5 x 10 5 to 3.2 x 10 3 mL/g as the pH changes from 4.5 to 9.5, whereas type II materials have relatively low sorption capabilities with K d remaining more or less constant (1.1 x 10 3 - 1.8 x 10 3 mL/g) over a similar pH range. The difference in sorption behavior between the two types of materials is attributed to the distribution of surface functional groups. The predominant surface groups are identified to be carboxylic and phenolic groups. The carboxylic group can be further divided into three subgroups A, B, and C in the order of increasing acidity. The high sorption capabilities of type I materials are found to be caused by the presence of a large fraction of carboxylic subgroups A and B, while the low sorption capabilities of type II materials are due to the exclusive presence of phenolic and carboxylic subgroup C. Therefore, the performance of activated carbon for removing TcO 4 - can be improved by enhancing the formation of carboxylic subgroups A and B during material processing

Accurate information is lacking on the extent of transportation as a source of physical activity, on the physical activity gains from public transportation use, and on the extent to which population shifts in the use of transportation modes could increase the percentage of people reaching official physical activity recommendations. In 2012-2013, 234 participants of the RECORD GPS Study (French Paris region, median age = 58) wore a portable GPS receiver and an accelerometer for 7 consecutive days and completed a 7-day GPS-based mobility survey (participation rate = 57.1%). Information on transportation modes and accelerometry data aggregated at the trip level [number of steps taken, energy expended, moderate to vigorous physical activity (MVPA), and sedentary time] were available for 7,644 trips. Associations between transportation modes and accelerometer-derived physical activity were estimated at the trip level with multilevel linear models. Participants spent a median of 1 h 58 min per day in transportation (8.2% of total time). Thirty-eight per-cent of steps taken, 31% of energy expended, and 33% of MVPA over 7 days were attributable to transportation. Walking and biking trips but also public transportation trips with all four transit modes examined were associated with greater steps, MVPA, and energy expenditure when compared to trips by personal motorized vehicle. Two simulated scenarios, implying a shift of approximately 14% and 33% of all motorized trips to public transportation or walking, were associated with a predicted 6 point and 13 point increase in the percentage of participants achieving the current physical activity recommendation. Collecting data with GPS receivers, accelerometers, and a GPS-based electronic mobility survey of activities and transportation modes allowed us to investigate relationships between transportation modes and physical activity at the trip level. Our findings suggest that an increase in active transportation

Background: Lecture is a common traditional method for teaching, but it may not stimulate higher order thinking and students may also be hesitant to express and interact. The postgraduate (PG) students are less involved with undergraduate (UG) teaching. Team based small group active learning method can contribute to better learning experience. Aim: To-promote active learning skills among the UG students using small group teaching methods involving PG students as facilitators to impart hands-on supervised training in teaching and managerial skills. Methodology: After Institutional approval under faculty supervision 92 UGs and 8 PGs participated in 6 small group sessions utilizing the jigsaw technique. Feedback was collected from both. Observations: Undergraduate Feedback (Percentage of Students Agreed): Learning in small groups was a good experience as it helped in better understanding of the subject (72%), students explored multiple reading resources (79%), they were actively involved in self-learning (88%), students reported initial apprehension of performance (71%), identified their learning gaps (86%), team enhanced their learning process (71%), informal learning in place of lecture was a welcome change (86%), it improved their communication skills (82%), small group learning can be useful for future self-learning (75%). Postgraduate Feedback: Majority performed facilitation for first time, perceived their performance as good (75%), it was helpful in self-learning (100%), felt confident of managing students in small groups (100%), as facilitator they improved their teaching skills, found it more useful and better identified own learning gaps (87.5%). Conclusions: Learning in small groups adopting team based approach involving both UGs and PGs promoted active learning in both and enhanced the teaching skills of the PGs. PMID:26380201

Recommended survey designs for occupancy modelling using motion-activated cameras: insights from empirical wildlife data

Directory of Open Access Journals (Sweden)

Full Text Available Motion-activated cameras are a versatile tool that wildlife biologists can use for sampling wild animal populations to estimate species occurrence. Occupancy modelling provides a flexible framework for the analysis of these data; explicitly recognizing that given a species occupies an area the probability of detecting it is often less than one. Despite the number of studies using camera data in an occupancy framework, there is only limited guidance from the scientific literature about survey design trade-offs when using motion-activated cameras. A fuller understanding of these trade-offs will allow researchers to maximise available resources and determine whether the objectives of a monitoring program or research study are achievable. We use an empirical dataset collected from 40 cameras deployed across 160 km2 of the Western Slope of Colorado, USA to explore how survey effort (number of cameras deployed and the length of sampling period affects the accuracy and precision (i.e., error of the occupancy estimate for ten mammal and three virtual species. We do this using a simulation approach where species occupancy and detection parameters were informed by empirical data from motion-activated cameras. A total of 54 survey designs were considered by varying combinations of sites (10–120 cameras and occasions (20–120 survey days. Our findings demonstrate that increasing total sampling effort generally decreases error associated with the occupancy estimate, but changing the number of sites or sampling duration can have very different results, depending on whether a species is spatially common or rare (occupancy = ψ and easy or hard to detect when available (detection probability = p. For rare species with a low probability of detection (i.e., raccoon and spotted skunk the required survey effort includes maximizing the number of sites and the number of survey days, often to a level that may be logistically unrealistic for many studies.

Physical activity is a health-enhancing behavior, and most U.S. adults do not meet the 2008 Physical Activity Guidelines for Americans. Active transportation, such as by walking or bicycling, is one way that persons can be physically active. No comprehensive, multiyear assessments of active transportation surveillance in the United States have been conducted. 1999-2012. Five surveillance systems assess one or more components of active transportation. The American Community Survey and the National Household Travel Survey (NHTS) both assess the mode of transportation to work in the past week. From these systems, the proportion of respondents who reported walking or bicycling to work can be calculated. NHTS and the American Time Use Survey include 1-day assessments of trips or activities. With that information, the proportion of respondents who report any walking or bicycling for transportation can be calculated. The National Health and Nutrition Examination Survey and the National Health Interview Survey both assess recent (i.e., in the past week or past month) habitual physical activity behaviors, including those performed during active travel. From these systems, the proportion of respondents who report any recent habitual active transportation can be calculated. The prevalence of active transportation as the primary commute mode to work in the past week ranged from 2.6% to 3.4%. The 1-day assessment indicated that the prevalence of any active transportation ranged from 10.5% to 18.5%. The prevalence of any habitual active transportation ranged from 23.9% to 31.4%. No consistent trends in active transportation across time periods and surveillance systems were identified. Among systems, active transportation was usually more common among men, younger respondents, and minority racial/ethnic groups. Among education groups, the highest prevalence of active transportation was usually among the least or most educated groups, and active transportation tended to be more

We have developed the ''S IX '' statistic to identify bright, highly likely active galactic nucleus (AGN) candidates solely on the basis of Wide-field Infrared Survey Explorer (WISE), Two Micron All-Sky Survey (2MASS), and ROSAT all-sky survey (RASS) data. This statistic was optimized with data from the preliminary WISE survey and the Sloan Digital Sky Survey, and tested with Lick 3 m Kast spectroscopy. We find that sources with S IX 95% likelihood of being an AGN (defined in this paper as a Seyfert 1, quasar, or blazar). This statistic was then applied to the full WISE/2MASS/RASS dataset, including the final WISE data release, to yield the ''W2R'' sample of 4316 sources with S IX 2 , permitting construction of AGN samples in any sufficiently large region of sky.

Skala, Chija; Slater, Timothy F.; Adams, Jeffrey P.

2000-08-01

Large-lecture introductory astronomy courses for undergraduate, non-science majors present numerous problems for faculty. As part of a systematic effort to improve the course learning environment, a series of small-group, collaborative learning activities were implemented in an otherwise conventional lecture astronomy survey course. These activities were used once each week during the regularly scheduled lecture period. After eight weeks, ten focus group interviews were conducted to qualitatively assess the impact and dynamics of these small group learning activities. Overall, the data strongly suggest that students enjoy participating in the in-class learning activities in learning teams of three to four students. These students firmly believe that they are learning more than they would from lectures alone. Inductive analysis of the transcripts revealed five major themes prevalent among the students' perspectives: (1) self-formed, cooperative group composition and formation should be more regulated by the instructor; (2) team members' assigned rolls should be less formally structured by the instructors; (3) cooperative groups helped in learning the course content; (4) time constraints on lectures and activities need to be more carefully aligned; and (5) gender issues can exist within the groups. These themes serve as a guide for instructors who are developing instructional interventions for large lecture courses.

2017-04-01

Full Text Available In this article, we present our findings regarding promoting group drawing activities in order to facilitate the learning of systemic aspects of projects. We discuss the approach we used to engage the students and foster learning in our classes. We used group drawing activities in two project management undergraduate courses. The courses, which involved 41 students, took place during the second semester of 2016 in a public university in Brazil. We conducted qualitative research, using qualitative observation and focus group interviews. In order to gauge the effects of the use of this educational technique, we followed the five-phased qualitative analysis method, combined with a systems analysis of the data obtained from observation. Five recurrent themes emerged: 1 Making drawings in groups helps content retention and facilitates connections between the concepts explained by the professor; 2 Making drawings in groups promotes knowledge sharing among team members; 3 Making drawings in group fosters creativity and communication between students; 4 Drawing in groups reduces the students’ boredom, makes the lecture more dynamic and interesting; 5 Drawing in groups reinforces bonds between students. Our systems analysis suggests that group drawing improves student participation in classroom activities, strengthens bonds between students, and enhances learning.

public to establish the extent of exposure to various pathways. Some interviewees are known in advance (from previous investigations) and specifically targeted at their residence, whereas others are interviewed whilst undertaking a specific activity of a known pathway. For example, walkers over sediment may be queried to determine their yearly exposure times. Uncommon pathways may be discovered with skilled interview techniques either from the individual that they apply to or by hearing reports of activities taking place (e.g. poaching). Some examples of uncommon aquatic pathways include consumption of razor shell or sea mice, and the use of seaweed as a soil conditioner. Surveys into terrestrial pathways have led to the inclusion of additional food groups in assessments, including goat meat, freshwater plants and algae, freshwater crustaceans and terrestrial molluscs. Once obtained, survey data are input into a purpose-built database and analysed. Critical rates are derived and may be subsequently applied in dose assessments for regulation purposes. (authors)

The European Safeguards Research and Development Association, ESARDA, has one of the largest coordinated safeguards and development programs in the world. There are several working groups for specific R and D activities. One of these is the ''ESARDA Working Group on Techniques and Standards for non-Destructive Analysis''. The NDA working group has initiated the international project of the preparation of uranium oxide certified reference materials for the gamma spectrometric determination of the enrichment, which are made in a collaboration with the US NBS and the European Communities' Central Bureau for Nuclear Measurements, CBNM, at Geel. The possibility of a similar type of reference material for Pu isotopic abundance measurements is investigated at CBNM, and the pilot samples may become available for intercomparisons. Safeguards acceptability and users manual have been considered carefully. The working group has undertaken an intercomparison on the determination of plutonium isotopic ratios by gamma spectrometry, using NBS-SRM's-946, -947 and 948. A new exercise on 0,5 gram samples of seven different isotopic compositions samples will be executed under the name PIDIE (Plutonium Isotopic Determination Intercomparison Exercise)

To document the frequency of policies and activities in support of mentoring practices at institutions receiving a U.S. National Institutes of Health's Clinical and Translational Science Award (CTSA). The study consisted of a 69-item survey with questions about the inclusion (formal or informal) of policies, activities, and structures supporting mentoring within CTSA-sponsored research (i.e., KL2 programs) and, more broadly, in the CTSA's home institution. The survey, conducted from November 2010 through January 2011, was sent to the 55 institutions awarded CTSAs at the time of the survey. Follow-up phone interviews were conducted to clarify responses as needed. Fifty-one of 55 (92%) institutions completed the survey for institutional programs and 53 of 55 (96%) for KL2 programs. Responses regarding policies and activities involving mentor criteria, mentor-mentee relationship, incentives, and evaluative mechanisms revealed considerable variability between KL2 and institutional programs in some areas, such as having mentor qualification criteria and processes to evaluate mentors. The survey also identified areas, such as training and women and minority mentoring programs, where there was frequent sharing of activities between the institutional and KL2 programs. KL2 programs and institutional programs tend to have different preferences for policies versus activities to optimize qualification of mentors, the mentor-mentee relationship, incentives, and evaluation mechanisms. Frequently, these elements are informal. Individuals in charge of implementing and maintaining mentoring initiatives can use the results of the study to consider their current mentoring policies, structures, and activities by comparing them with national patterns within CTSA institutions.

Proper physical activities are known to be helpful in the prevention and management of chronic diseases. However, the physical activity level of patients with chronic diseases is low. Therefore, this study aimed to investigate the physical activity compliance of patients with hypertension, diabetes, and dyslipidemia in Korea. This study analyzed the 2010-2012 Fifth Korean National Health and Nutrition Examination Survey data. We included 13,873 individuals in the analysis. The level of physical activity compliance was measured by performing multivariate logistic regression analyses. In the univariate analysis, the subjects with hypertension or diabetes tended to comply with the physical activity guidelines less faithfully than their healthy counterparts. The proportion of subjects with hypertension who were insufficiently physically active was 65.4% among the men and 75.8% among the women. For diabetes, the proportions were 66.7% and 76.8%, respectively. No significant difference was found between the subjects with dyslipidemia and their healthy counterparts. In the multivariate logistic regression analysis, no significant difference in physical activity compliance was observed between the subjects with hypertension, diabetes, or dyslipidemia and their healthy counterparts for both sexes. The patients with hypertension or diabetes tended to have lower physical activity prevlaence than their healthy counterparts. However, for dyslipidemia, no significant difference was found between the two groups. Given the significance of physical activities in the management of chronic diseases, the physical activities of these patients need to be improved.

The use of scientific data about the roles and the impact of pharmacists is suboptimal. The objective is to evaluate the opinion and attitude of expert pharmacists on the measurement of indicators for the pharmaceuticals activities, sharing and appropriation of scientific knowledge and the place of the website "Impact Pharmacie". This is a descriptive cross-sectional study. Four expert groups were interviewed (hematology-oncology, intensive care, emergency and infectious diseases). To achieve the objective, a preliminary evaluation followed by a semi-structured interview by teleconference was organized for each group. Twenty pharmacists were invited and 18 participated in the survey and 19 in interviews. Ten out of 18 and 2 out of 18 were collecting descriptive and impact indicators respectively. The use of these indicators by pharmacists was limited. Pharmacists had difficulties determining precise indicators measuring their impact but the majority would choose indicators related to medication errors or adverse drug event monitoring. The keywords mentioned by panelists about the usefulness of the site were "to guide", "to help prioritize", "to think", "to (re) structure the activity" and "time saving". To optimize website use, participants targeted journal club visioconferences, targeted activities in professional meetings and through various organizations. Experts pharmacists recognized the importance of monitoring their practice and a better use of the current available data may ensure the provision of consistent pharmaceutical services. They recognized the need to better educate pharmacists about using and disseminating data about the role and the impact of pharmacists including the website Impact Pharmacy.

Our national survey in Hungary began in 1992, in the most beautiful European village: Matraderecske. In the dwellings of Matraderecske there is a wide range of radon activity concentration from 50 Bq/m3 to 2600 Bq/m3 in yearly average. In the first two years we have learnt the whole process of the measurement in this village: how to communicate with the local people with the help of the local students and their physics teacher, how to handle CR 39 track detectors in a reliable way, and how to evaluate the detectors by a home made semi-automaton. The results in this village encouraged us to extend our survey to find a much wider statistics to see better the correlation between cancer cases and low dose radiation

The LAMOST spectral survey provides a rich databases for studying stellar spectroscopic properties and chromospheric activity. We cross-matched a total of 105,287 periodic variable stars from several photometric surveys and databases (CSS, LINEAR, Kepler, a recently updated eclipsing star catalogue, ASAS, NSVS, some part of SuperWASP survey, variable stars from the Tsinghua University-NAOC Transient Survey, and other objects from some new references) with four million stellar spectra published in the LAMOST data release 2 (DR2). We found 15,955 spectra for 11,469 stars (including 5398 eclipsing binaries). We calculated their equivalent widths (EWs) of their Hα, Hβ, Hγ, Hδ and Caii H lines. Using the Hα line EW, we found 447 spectra with emission above continuum for a total of 316 stars (178 eclipsing binaries). We identified 86 active stars (including 44 eclipsing binaries) with repeated LAMOST spectra. A total of 68 stars (including 34 eclipsing binaries) show chromospheric activity variability. We also found LAMOST spectra of 12 cataclysmic variables, five of which show chromospheric activity variability. We also made photometric follow-up studies of three short period targets (DY CVn, HAT-192-0001481, and LAMOST J164933.24+141255.0) using the Xinglong 60-cm telescope and the SARA 90-cm and 1-m telescopes, and obtained new BVRI CCD light curves. We analyzed these light curves and obtained orbital and starspot parameters. We detected the first flare event with a huge brightness increase of more than about 1.5 magnitudes in R filter in LAMOST J164933.24+141255.0.

The platinum-group metals (PGMs), Ru, Rh, Pd, Os, Ir and Pt, are widely used as catalysts in petroleum and chemical processes. They find wide applications in automotive exhaust-gas control converters and are of immense importance to the electronics industry. They are found in many items of jewellery and serve to an increasing extent as a form of investment. The PGMs are extracted in minute quantities from a limited number of ores, found mainly in S. Africa and the USSR. They are concentrated and separated from each other by elaborate chemical processes. Because of their great intrinsic value (Pt $650 per oz; Rh $1400 per oz), the recycling of the PGMs from literally hundreds of different forms of scrap is an essential factor in the overall management of the PGM economy. In this survey emphasis is placed on the need to tailor the analytical method according to (a) the environment in which the PGMs occur, (b) the individual PGM concentrations, and (c) the desired sensitivity and precision. The factors which determine the choice of chemical, physicochemical and/or instrumental approaches are discussed. They are further commented on in extensive presentations of dissolution and separation techniques and methods for the final measurement of individual PGMs. Appendices are provided which present the compositions and sources of the products most frequently encountered in PGM analysis, along with information on methods of decomposition, separations required, type of separation, and final determination.

Despite the health-enhancing benefits of physical activity, a large segment of the Malaysian population does not engage in regular physical activity at the recommended level. This study aimed to determine physical activity patterns and the associated sociodemographic correlates of physical activity. Data on physical activity were obtained from the National Health and Morbidity Survey (NHMS) 2011, a nationally representative, population-based cross-sectional study. A two-stage stratified sampling method was used to select a representative sample of Malaysian adults aged 16 years and above. A total of 19,145 adults aged 16 years and above were recruited, and face-to-face interviews were conducted using the International Physical Activity Questionnaire (IPAQ), short version. The correlates for physical activity were identified using multivariate analysis. In this study, 64.3% (95%CI: 63.1-65.5) of Malaysian adults aged 16 and above were physically active, but overall physical activity levels decreased with advancing age. Men, rural residents, 'other' ethnic groups, and married women were more likely to demonstrate higher levels of physical activity. Approximately 65% of Malaysian adults were physically active. However, it is recommended that health promotions for active lifestyles should be targeted to the least active segments, which constitute more than a quarter of the Malaysian population.

Does chess instruction improve mathematical problem-solving ability? Two experimental studies with an active control group.

Science.gov (United States)

Sala, Giovanni; Gobet, Fernand

2017-12-01

It has been proposed that playing chess enables children to improve their ability in mathematics. These claims have been recently evaluated in a meta-analysis (Sala & Gobet, 2016, Educational Research Review, 18, 46-57), which indicated a significant effect in favor of the groups playing chess. However, the meta-analysis also showed that most of the reviewed studies used a poor experimental design (in particular, they lacked an active control group). We ran two experiments that used a three-group design including both an active and a passive control group, with a focus on mathematical ability. In the first experiment (N = 233), a group of third and fourth graders was taught chess for 25 hours and tested on mathematical problem-solving tasks. Participants also filled in a questionnaire assessing their meta-cognitive ability for mathematics problems. The group playing chess was compared to an active control group (playing checkers) and a passive control group. The three groups showed no statistically significant difference in mathematical problem-solving or metacognitive abilities in the posttest. The second experiment (N = 52) broadly used the same design, but the Oriental game of Go replaced checkers in the active control group. While the chess-treated group and the passive control group slightly outperformed the active control group with mathematical problem solving, the differences were not statistically significant. No differences were found with respect to metacognitive ability. These results suggest that the effects (if any) of chess instruction, when rigorously tested, are modest and that such interventions should not replace the traditional curriculum in mathematics.

The MightyMedic (Multidisciplinary International Group for Hemapheresis TherapY and MEtabolic DIsturbances Contrast) Working Group has been founded in 2013. The leading idea was to establish an international network of interdisciplinary nature aimed at working to cross national borders research projects, clinical trials, educational initiatives (meetings, workshops, summer schools) in the field of metabolic diseases, namely hyperlipidemias, and diabetes, preventive cardiology, and atherosclerosis. Therapeutic apheresis, its indications and techniques, is a parallel field of investigation. The first on-line survey of the Group has been completed in the first half of 2014. The survey included # 24 Centers in Italy, Germany, Greece, UK, Sweden, Japan and USA. Relevant data have been collected on current practice in diagnosis, therapy and follow-up of dyslipidemias. 240 subjects with hyperlipidemia and treated with lipoprotein apheresis have been reported in the survey, but a large percentage of patients (35%) who could benefit from this therapeutic option are still treated by conventional drug approach. Genetic molecular diagnosis is performed in only 33% of patients while Lipoprotein(a) (Lp(a)) is included in cardiovascular disease risk assessment in 71% of participating Centers. New detailed investigations and prospective multicenter studies are needed to evaluate changes induced by the impact of updated indications and strategies, as well as new treatment options, targeting standardization of therapeutic and diagnostic approaches.

Focus group report - part II

International Nuclear Information System (INIS)

1997-12-01

The Waste Policy Institute, through a cooperative agreement with the U.S. Department of Energy (DOE) Office of Science and Technology (OST) conducted a focus group with members of the Hanford Advisory Board (HAB), interviews with tribal government representatives, and a survey of Oak Ridge Local Oversight Committee (LOC) and Site Specific Advisory Board (SSAB) members. The purpose was to understand what members of the interested and involved public want to know about technology development and ways to get that information to them. These data collection activities were used as a follow-up to two previously held focus groups with the general public near Idaho National Engineering and Environmental Laboratory (INEEL) and the Savannah River Site (SRS). Most participants from the first two focus groups said they did not have time and/or were not interested in participating in technology decision-making. They said they would prefer to defer to members of their communities who are interested and want to be involved in technology decision-making

More than 2 billion people worldwide now use social networking sites, with an increasing number of users accessing these sites to obtain health information and engage in emotional support. Yet, investigation of social networking sites in the context of cleft lip and/or palate (CL/P) has been scarce. Real-time data posted during 2 weeks in April 2017 were collected from 2 existing private Facebook groups (hosted by the Cleft Lip and Palate Association United Kingdom) using video screen capture software. The number of posts, comments, unique contributors, and post "likes" was recorded, as well as the type and theme of each post. Data relating to the benefits and challenges of participation in the 2 groups were also collected via an online survey. A content analysis of real-time data identified perioperative care, associated syndromes, and dental health to be particular areas of concern for parents/caregivers. Expectations, experiences, and outcomes of further treatment were key topics of discussion for adults with CL/P. Common benefits of the groups included the ability to connect with others, learn about local events, give and receive emotional support, and obtain quick responses to queries in a semi-anonymous environment. Disadvantages of the groups included a reliance upon opinion rather than medical fact and the frequent use of inappropriate terminology. Social networking sites appear to be a helpful source of health-related information and peer support for the CL/P population, yet closer monitoring of these groups may be required.

2006-01-01

This study examines the formation of group cohesion and social support in exercise classes among former sedentary adults, participating in a Danish community-based intervention. Furthermore, the aim is to analyze the impact of this process on exercise activity among the participants. A multimethod...... approach was used, analyzing both survey data and 18 personal interviews collected among 87 participants who completed the intervention project. Analysis was performed according to the grounded theory method. The formation of group cohesion was conditioned by the social composition of the group......, the teaching ability by the instructors, and the activity by itself. The cohesive group was characterized by an attitude of mutual support toward exercise activities. This mutual support facilitated development of self-efficacy beliefs among the participants improving their mastery expectation regarding...

Report on the Survey on Regulation of Site Selection and Preparation

Webster, Philip

2010-01-01

At its first meeting in May 2008, the Working Group discussed a task to 'Prepare a report reviewing the various practices used by regulators in the regulation of nuclear power plant siting. The report should consider regulator practices on sites where a mixture of activities are taking place (e.g. operating units, new construction, decommissioning, etc) including organization of the regulators organisation, methods, systems, etc.'. Following discussion, the Working Group assigned an Action 1-5 to 'develop a survey on the regulation of nuclear sites including seismicity issues, security issues, multi-units aspects and regulator practices on sites where a mixture of activities are taking place (e.g. operating units, new construction, decommissioning, etc.)'. The Survey was prepared and issued by the NEA in July 2008 with a request to the member states to provide their responses by the next meeting of the Working Group in October 2008. In addition to addressing the specific topics actioned by the Working Group, the Survey also investigated the broader context of siting, in order to address the Mandate that had been approved by the CNRA. The questions in the survey therefore covered the topics of site evaluation, site selection, regulatory approval, site preparation and regulatory oversight. A topic of particular interest was to what extent IAEA guidance on site evaluation was followed. The survey considered the possibility that a body other than the safety regulator may approve the choice of site or permit the applicant to start to prepare it. The survey also investigated the existence of formal requirements and informal expectations, recognizing that these both form part of the regulatory tool-kit. Responses were received from all twelve member states that were then members of the Working Group. The responses were reviewed at the second meeting of the Working Group in October 2008. In general, it could be stated that new reactors are licensed in

Resident-Assisted Montessori Programming (RAMP): training persons with dementia to serve as group activity leaders.

Camp, Cameron J; Skrajner, Michael J

2004-06-01

The purpose of this study was to determine the effects of an activity implemented by means of Resident-Assisted Montessori Programming (RAMP). Four persons with early-stage dementia were trained to serve as leaders for a small-group activity played by nine persons with more advanced dementia. Assessments of leaders' ability to learn the procedures of leading a group, as well as their satisfaction with this role, were taken, as were measures of players' engagement and affect during standard activities programming and RAMP activities. Leaders demonstrated the potential to fill the role of group activity leader effectively, and they expressed a high level of satisfaction with this role. Players' levels of positive engagement and pleasure during the RAMP activity were higher than during standard group activities. This study suggests that to the extent that procedural learning is available to persons with early-stage dementia, especially when they are assisted with external cueing, these individuals can successfully fill the role of volunteers when working with persons with more advanced dementia. This can provide a meaningful social role for leaders and increase access to high quality activities programming for large numbers of persons with dementia.

Survey of United States uranium marketing activity

International Nuclear Information System (INIS)

1978-05-01

Uranium marketing activity was much lower in 1977 than during 1976, which was the largest procurement year to date. Results from the survey suggest that there is an adequate supply of uranium--at least through 1985--in light of apparent buyer concepts of demand. Unfilled requirements were reduced by additional procurement and slippages in requirements. U.S. buyers continue to concentrate almost exclusively on U.S. sources for procurement. Buyer and producer inventories changed only slightly during the year. The average price reported for 1977 deliveries was $19.75 per pound of U 3 O 8 , compared to the $17.20 estimate reported as of July 1, 1977. An average of $17.40 was reported for 1978. Settlements of market prices in 1977 averaged $41.50 and for 1978 averaged $43.95. Most market price contracts have a base price. These prices are much higher than average contract prics and are closer to market price settlements. Producers estimate they will be able to offer for sale substantial additional quantities of uranium, indicating that they expect to expand production considerably

The burden of non-communicable diseases is increasing in Malaysia. Insufficient Physical Activity, which is an important risk factor for non-communicable diseases, is less researched in Malaysia. We aimed to assess the level of physical activity and identify its correlates. An online survey was carried out during October, 2011 in the University Tunku Abdul Rahman by the opinion poll research committee. Young adults answered the Short International Physical Activity Questionnaire and a questionnaire about factors according to a socio-ecological model which was adapted from published studies. Metabolic equivalent (MET)-hours and MET-minutes were calculated. Physical activity was classified as sufficient when MET-minutes were > 840. The mean age of the 474 participants was 22.4 years (S.D. = 4.7), and 253 (53.4%) were females. Their mean and median of MET-hours of PA done during the previous seven days were 31.36 (S.D., 52.19) and 14.7 (IQR, 5.77-32.07), respectively. Physical activity done was sufficient among 242 (51.1%) participants. Using univariate analysis, being male, good self-rated health, positive intention, self-efficacy, perceived benefits, social support, and availability of facilities were associated with sufficient physical activity. Using multivariate analysis sufficient physical activity was associated with participants' intention (OR 0.75, 95% CIs 0.64, 0.88), self-efficacy (OR 0.91, 95% CIs 0.85, 0.97) and facility availability (OR 0.81, 95% CIs 0.73, 0.91). The proportion of participants with sufficient physical activity was low. Positive intention and self-efficacy associated with sufficient physical activity should be supported by availability of facilities and a safely-built environment. A nationwide survey about physical and associated socialecological factors is needed to design rational health promotion strategies.

2010-11-17

In recent years, problems like insufficient coordination, low efficiency, and heavy working load in national communicable disease surveillance systems in China have been pointed out by many researchers. To strengthen the national communicable disease surveillance systems becomes an immediate concern. Since the World Health Organization has recommended that a structured approach to strengthen national communicable disease surveillance must include an evaluation to existing systems which usually begins with a systematic description, we conducted the first survey for communicable disease surveillance systems in China, in order to understand the situation of core and support surveillance activities at province-level and county-level centers for disease control and prevention (CDCs). A nationwide survey was conducted by mail between May and October 2006 to investigate the implementation of core and support activities of the Notifiable Disease Reporting System (NDRS) and disease-specific surveillance systems in all of the 31 province-level and selected 14 county-level CDCs in Mainland China The comments on the performance of communicable disease surveillance systems were also collected from the directors of CDCs in this survey. The core activities of NDRS such as confirmation, reporting and analysis and some support activities such as supervision and staff training were found sufficient in both province-level and county-level surveyed CDCs, but other support activities including information feedback, equipment and financial support need to be strengthened in most of the investigated CDCs. A total of 47 communicable diseases or syndromes were under surveillance at province level, and 20 diseases or syndromes at county level. The activities among different disease-specific surveillance systems varied widely. Acute flaccid paralysis (AFP), measles and tuberculosis (TB) surveillance systems got relatively high recognition both at province level and county level. China has

A Small-Group Activity Introducing the Use and Interpretation of BLAST

Directory of Open Access Journals (Sweden)

Peter D. Newell

2013-08-01

Full Text Available As biological sequence data are generated at an ever increasing rate, the role of bioinformatics in biological research also grows. Students must be trained to complete and interpret bioinformatic searches to enable them to effectively utilize the trove of sequence data available. A key bioinformatic tool for sequence comparison and genome database searching is BLAST (Basic Local Alignment Search Tool. BLAST identifies sequences in a database that are similar to the entered query sequence, and ranks them based on the length and quality of the alignment. Our goal was to introduce sophomore and junior level undergraduate students to the basic functions and uses of BLAST with a small group activity lasting a single class period. The activity provides students an opportunity to perform a BLAST search, interpret the data output, and use the data to make inferences about bacterial cell envelope structure. The activity consists of two parts. Part 1 is a handout to be completed prior to class, complete with video tutorial, that reviews cell envelope structure, introduces key terms, and allows students to familiarize themselves with the mechanics of a BLAST search. Part 2 consists of a hands-on, web-based small group activity to be completed during the class period. Evaluation of the activity through student performance assessments suggests that students who complete the activity can better interpret the BLAST output parameters % query coverage and % max identity. While the topic of the activity is bacterial cell wall structure, it could be adapted to address other biological concepts.

Patient Blood Management (PBM) in Europe is a working group of the European Blood Alliance with the initial objective to identify the starting position of the participating hospitals regarding PBM for benchmarking purposes, and to derive good practices in PBM from the experience and expertise in the participating teams with the further aim of implementing and strengthening these practices in the participating hospitals. We conducted two surveys in seven university hospitals in Europe: Survey on top indications for red blood cell use regarding usage of red blood cells during 1 week and Survey on PBM organization and activities. A total of 3320 units of red blood cells were transfused in 1 week at the seven hospitals. Overall, 61% of red cell units were transfused to medical patients and 36% to surgical patients, although there was much variation between hospitals. The organization and activities of PBM in the seven hospitals were variable, but there was a common focus on optimizing the treatment of bleeding patients, monitoring the use of blood components and treatment of preoperative anaemia. Although the seven hospitals provide a similar range of clinical services, there was variation in transfusion rates between them. Further, there was variable implementation of PBM activities and monitoring of transfusion practice. These findings provide a baseline to develop joint action plans to further implement and strengthen PBM across a number of hospitals in Europe. © 2016 International Society of Blood Transfusion.

Land subsidence, the loss of surface elevation as a result of the removal of subsurface support, affects every state in the United States. More than 17,000 mi2 of land in the United States has been lowered by the various processes that produce land subsidence with annual costs from resulting flooding and structural damage that exceed $125 million. It is estimated that an additional $400 million is spent nationwide in attempts to control subsidence. Common causes of land subsidence include the removal of oil, gas, and water from underground reservoirs; dissolution of limestone aquifers (sinkholes); underground mining activities; drainage of organic soils; and hydrocompaction (the initial wetting of dry soils). Overdrafting of aquifers is the major cause of areally extensive land subsidence, and as ground-water pumping increases, land subsidence also will increase. Land subsidence and its effects on engineering structures have been recognized for centuries, but it was not until this century that the processes that produce land subsidence were identified and understood. In 1928, while working with field data from a test of the Dakota Sandstone aquifer, O.E. Meinzer of the U.S. Geological Survey recognized the compressibility of aquifers. Around the same time, Karl Terzaghi, a soil scientist working at Harvard University, developed the one-dimensional consolidation theory that provided a quantitative means of predicting soil compaction resulting from the drainage of compressible soils. Thus, with the recognition of the compressibility of aquifers (Meinzer), and the development of a quantitative means of predicting soil compaction as a consequence of the reduction of intergranular pore pressure (Terzaghi), the theory of aquifer-system compaction was formed. With the widespread availa- bility of electric power in rural areas, and the advent of the deep turbine pump, ground-water withdrawals increased dramatically throughout the country in the 1940's and 1950's.

There is a global move from individual to group housing of gestating sows. In the European Union, individual gestating stalls will be banned by 2013. Just like in other industrialized regions, these stalls have been the standard housing system for intensively kept sows from the 1960s onward in the Flemish region of Belgium. Because the socioeconomic consequences for the pig industry may be far-reaching and because farmer attitude may influence the realization of the hoped-for improvement in animal welfare in practice, we conducted a survey from 2003 until 2009 among representative samples of Flemish pig producers every 2 yr. The share of farms with group housing increased from 10.5% in 2003 to 29.8% in 2007, but then dropped to 24.6% in 2009. It appears that after 2005 users of old group housing systems in particular stopped farming. Because sow herd size increased more on farms with vs. without group housing and because the proportion of the herd that was group-housed also tended to increase between 2003 to 2009, the change to group housing took place faster when expressed at the level of the sow (from 9.1% in 2003 to 34.1% in 2009) instead of farm. The percentage of farmers planning to convert to group housing within 2 yr was 4.1% in 2003, and 6 to 7% thereafter. These were typically young farmers (P = 0.006) with a large sow herd (P manual feed delivery. User satisfaction was generally high but depended on whether or not all gestating sows were kept in group (P importance of economic reasons (P = 0.007) and type of labor (P = 0.043) decreased with the age of the system. In 2003 and 2005 the main reason for not having converted to group housing was that farmers would stop keeping sows by 2013. In 2007 and 2009 the reasons mainly concerned uncertainty about the future and maximally delaying the conversion. Belgium is one of the European Union countries where the pig industry is expected to undergo drastic changes during the few years remaining before the ban on

Geophysical survey work plan for White Wing Scrap Yard (Waste Area Grouping 11) at Oak Ridge National Laboratory, Oak Ridge, Tennessee

International Nuclear Information System (INIS)

1994-02-01

The White Wing Scrap Yard, located on the U.S. Department of Energy's Oak Ridge Reservation, served as an aboveground storage and disposal area for contaminated debris and scrap from the Oak Ridge K-25 Site, the Oak Ridge Y-12 Plant, and the Oak Ridge National laboratory. The site is believed to have been active from the early 1950s until the mid-1960s. A variety of materials were disposed of at the site, including contaminated steel tanks and vehicles. As an interim corrective action, a surface debris removal effort was initiated in November 1993 to reduce the potential threat to human health and the environment from the radionuclide-contaminated debris. Following this removal effort, a geophysical survey will be conducted across the site to locate and determine the lateral extent of buried nonindigenous materials. This survey will provide the data necessary to prepare a map showing areas of conductivity and magnetic intensity that vary from measured background values. These anomalies represent potential buried materials and therefore can be targeted for further evaluation. This work plan outlines the activities necessary to conduct the geophysical survey

Full Text Available Purpose. To examine relationships between leisure time physical activity (LTPA and health services utilization (H in a nationally representative sample of community-dwelling older adults. Methods. Cross-sectional data from 56,652 Canadian Community Health Survey respondents aged ≥ 50 years (48% M; 52% F; mean age 63.5 ± 10.2 years were stratified into three age groups and analysed using multivariate generalized linear modeling techniques. Participants were classified according to PA level based on self-reported daily energy expenditure. Nonleisure PA (NLPA was categorized into four levels ranging from mostly sitting to mostly lifting objects. Results. Active 50–65-year-old individuals were 27% less likely to report any GP consultations ORadj=0.73; P<0.001 and had 8% fewer GP consultations annually (IRRadj=0.92; P<0.01 than their inactive peers. Active persons aged 65–79 years were 18% less likely than inactive respondents to have been hospitalized overnight in the previous year (ORadj=0.82, P<0.05. Higher levels of NLPA were significantly associated with lower levels of HSU, across all age groups. Conclusion. Nonleisure PA appeared to be a stronger predictor of all types of HSU, particularly in the two oldest age groups. Considering strategies that focus on reducing time spent in sedentary activities may have a positive impact on reducing the demand for health services.

The impact of instructor grouping strategies on student efficacy in inquiry science labs: A phenomenological case study of grouping perceptions and strategies

Science.gov (United States)

Miller, Nathaniel J.

Abundant educational research has integrated Albert Bandura's concepts of self-efficacy and collective efficacy within educational settings. In this phenomenological case study, the investigation sought to capture the manifestation of self-efficacy and collective efficacy within inquiry-based science laboratory courses. Qualitative data was derived from student efficacy surveys, direct classroom observations, and three-tiered interviews with teacher participants. Four high school science instructors and their students from two school districts in Northern Illinois were selected to participate in the study. This study sought to identify instructor strategies or criteria used to formulate student laboratory groups and the impact of such groupings on student self-efficacy and collective efficacy. Open coding of interview transcripts, observation logs, and student surveys led to the development of eight emerging themes. These themes included the purpose of science laboratory activities, instructor grouping strategies, instructor roles, instructor's perceptions, science laboratory assessment, student interactions, learner self-perceptions, and grouping preferences. Results from the study suggest that some students were innately inclined to assume leadership roles, smaller groupings had greater participation from all group members, students had a strong preference for working collaboratively in groups, and students desired to maintain stable laboratory groups in lieu of periodically changing laboratory partners. As with all case study methodologies, the findings of the study were limited to the individual participants at research sites and were not generalizable to all science classrooms. Additional research in the realms of group size, group autonomy, and student interviews would provide even greater insights into the observed phenomena.

As social media (eg, Twitter) continues to gain widespread popularity, health research and practice organizations may consider combining it with other electronic media (e-media) channels (eg, Web sites, e-newsletters) within their communication plans. However, little is known about added benefits of using social media when trying to reach public health audiences about physical activity. Learn about current use and preference for e-media communication channels among physical activity researchers and practitioners. A Web-based survey was used, open for responses from August 20, 2015, through January 5, 2016. Survey participation was voluntary and anonymous. The survey was advertised through multiple channels targeting physical activity researchers and practitioners, including announcements on professional listservs and in e-newsletters, Twitter, and posts on Facebook pages of public health organizations. A total of 284 survey respondents had complete data. Typical use of e-media to receive, seek out, and share information about physical activity and health and what appeals to researchers and practitioners for professional use. Most respondents preferred non-social media channels to social media and these preferences did not differ widely when examining subgroups such as researchers versus practitioners or social media users versus nonusers. There were few differences by respondent demographics, though younger respondents reported using social media more than older respondents. However, limiting analyses to respondents who identified as social media users, only about 1% of respondents ranked social media sources as their preferred channels for information; thus, most people would continue to be reached if communication remained largely via non-social media e-media channels. The present study supports growing evidence that careful surveying of a target audience should be undertaken when considering new communication channels, as preference and use may not support the

A substantial proportion of US maternity care facilities engage in practices that are not evidence-based and that interfere with breastfeeding. The CDC Survey of Maternity Practices in Infant Nutrition and Care (mPINC) showed significant variation in maternity practices among US states. The purpose of this article is to use benchmarking techniques to identify states within relevant peer groups that were top performers on mPINC survey indicators related to breastfeeding support. We used 11 indicators of breastfeeding-related maternity care from the 2011 mPINC survey and benchmarking techniques to organize and compare hospital-based maternity practices across the 50 states and Washington, DC. We created peer categories for benchmarking first by region (grouping states by West, Midwest, South, and Northeast) and then by size (grouping states by the number of maternity facilities and dividing each region into approximately equal halves based on the number of facilities). Thirty-four states had scores high enough to serve as benchmarks, and 32 states had scores low enough to reflect the lowest score gap from the benchmark on at least 1 indicator. No state served as the benchmark on more than 5 indicators and no state was furthest from the benchmark on more than 7 indicators. The small peer group benchmarks in the South, West, and Midwest were better than the large peer group benchmarks on 91%, 82%, and 36% of the indicators, respectively. In the West large, the Midwest large, the Midwest small, and the South large peer groups, 4-6 benchmarks showed that less than 50% of hospitals have ideal practice in all states. The evaluation presents benchmarks for peer group state comparisons that provide potential and feasible targets for improvement.

Work site stress management: national survey results.

Science.gov (United States)

Fielding, J E

1989-12-01

The National Survey of Work Site Health Promotion Activities established baseline data on the frequency of nine types of health promotion activity at private work sites with more than 50 employees in the United States. Stress management activities were provided at 26.6% of work sites. Types of activities at those work sites with some stress management activity included group counseling (58.5%), individual counseling (39.3%), follow-up counseling (25.9%), special events (11.5%), providing information about stress (80.7%), providing a place to relax (64.8%), and making organizational changes to reduce employee stress (81.2%). Frequency of activities varied by industry type and by region of the country. Incidence of most types of activities did not increase as work site size increased, although the likelihood of having any of these activities did increase with work site size. Stress management activities were more likely to be present at work sites with a medical staff or health educator. An increase in output, productivity, or quality was the most frequently cited benefit (46.5%). Negative effects were reported at 2.6% of the work sites. Other health promotion activities found at the work sites surveyed included smoking cessation (61.8%), treatment and control of high blood pressure (36.7%), and weight control (34.7%). Employee Assistance Programs were responsible for stress management at 62% of the work sites with an Employee Assistance Program.

Genevieve Newton

2012-12-01

Full Text Available Breakout groups have been widely used under many different conditions, but the lack of published information related to their use in undergraduate settings highlights the need for research related to their use in this context. This paper describes a study investigating the use of breakout groups in undergraduate education as it specifically relates to teaching a large 4th year undergraduate Nutrition class in a physically constrained lecture space. In total, 220 students completed a midterm survey and 229 completed a final survey designed to measure student satisfaction. Survey results were further analyzed to measure relationships between student perception of breakout group effectiveness and (1 gender and (2 cumulative GPA. Results of both surveys revealed that over 85% of students either agreed or strongly agreed that using breakout groups enhanced their learning experience, with females showing a significantly greater level of satisfaction and higher final course grade than males. Although not stratified by gender, a consistent finding between surveys was a lower perception of breakout group effectiveness by students with a cumulative GPA above 90%. The majority of respondents felt that despite the awkward room space, the breakout groups were easy to create and participate in, which suggests that breakout groups can be successfully used in a large undergraduate classroom despite physical constraints. The findings of this work are relevant given the applicability of breakout groups to a wide range of disciplines, and the relative ease of integration into a traditional lecture format.Les enseignants ont recours aux petits groupes dans de nombreuses conditions différentes, cependant, le manque d’information publiée sur leur utilisation au premier cycle confirme la nécessité d’effectuer des recherches sur ce format dans ce contexte.

Designing an intervention to increase physical activity is important to be based on the health care settings resources and be acceptable by the subject group. This study was designed to assess and compare the effect of the goal setting strategy with a group education method on increasing the physical activity of mothers of children aged 1 to 5. Mothers who had at least one child of 1-5 years were randomized into two groups. The effect of 1) goal-setting strategy and 2) group education method on increasing physical activity was assessed and compared 1 month and 3 months after the intervention. Also, the weight, height, body mass index (BMI), waist and hip circumference, and well-being were compared between the two groups before and after the intervention. Physical activity level increased significantly after the intervention in the goal-setting group and it was significantly different between the two groups after intervention (P goal-setting group after the intervention. In the group education method, only the well-being score improved significantly (P goal-setting strategy to boost physical activity, improving the state of well-being and decreasing BMI, waist, and hip circumference.

To describe motor training and physical activity among preschoolers with cerebral palsy (CP) in Norway, and assess associations between child, parent, and motor intervention characteristics, and parent-reported child benefits from interventions. Survey of 360 parents and data from the Norwegian CP follow-up program. The response rate was 34%. During the six months preceding the time of the survey, 75% of the children performed gross-motor training, 73% fine-motor training, 80% manual stretching, and 67% participated regularly in physical activities. The training was highly goal-directed, intensive, frequently incorporated in daily routines, and often with a high level of parental involvement. The use of goals was associated with higher parent-reported child benefits for all types of interventions. Moreover, the positive relationship, which was indicated between frequency of training, parent education, and parent-reported child benefits of gross-motor training, was not seen for fine-motor training. Parent-reported child benefits support goal-directed motor interventions, and the use of everyday activities to increase practice of motor skills.

I arrived in Berkeley in October 1983 as a post-doc, and my appointment was at the Space Sciences Laboratory (SSL). During that time the group was very large, with multiple activities led by Charlie himself and also by Senior Fellows such as John Lacy, Dan Jaffe, and Al Betz at the top of the hill at Space Sciences. Another significant contingent of the Townes group was housed in Birge Hall on campus, led by Reinhard Genzel when he was an Assistant Professor in the Physics Department. Although the group encompassed two separate locations, it functioned as one large group. Either we rode with Charlie up and down the hill, or (if we were concerned about our safety!) we took the bus.

Multiple sclerosis (MS) is a debilitating disease and there is little research on support networks for people with MS (PwMS). More specifically, most studies on online support groups focus on those who actively participate in the group, whereas the majority of those who utilise online support groups do so in a passive way. This study therefore aimed to explore the experiences of non-active users of an online Facebook support group for PwMS. Emphasis was placed on the facilitators and the barriers that were associated with membership to this group. An exploratory qualitative research design was implemented, whereby thematic analysis was utilised to examine the ten semi-structured interviews that were conducted. Several facilitators were acquired through the online support group; namely emotional support (constant source of support, exposure to negative aspects of the disease), informational support (group as a source of knowledge, quality of information) and social companionship (place of belonging). Some barriers were also identified; namely emotional support (emotions lost online, response to messages, exposure to negative aspects of the disease), informational support (information posted on the group, misuse of group) and social companionship (non-active status). These findings demonstrate that the non-active members of the online support group for PwMS have valid reasons for their non-active membership status. More important, the findings suggest that the online Facebook support group provided the group members with an important support network in the form of emotional support, informational support and social companionship, despite their non-active membership status or the barriers that have been identified.

The ITER Test Blanket Working Group (TBWG) has continued its activities during the period of extension of the EDA with a revised charter on the co-ordination of the development work performed by the Parties and by the JCT leading to a co-ordinated test programme on ITER for a DEMO-relevant tritium breeding blanket. This follows earlier work carried out until July 1998, which formed part of the ITER Final Design Report (FDR), completed in 1998. Whilst the machine parameters for ITER-FEAT have been significantly revised compared to the FDR, testing of breeding blanket modules remains a main objective of the test programme and the development of a reactor-relevant breeding blanket to ensure tritium fuel self-sufficiency is recognized a key issue for fusion. Design work and R and D on breeding blanket concepts, including co-operation with the other Contacting Parties of the ITER-EDA for testing these concepts in ITER, are included in the work plans of the Parties

The present study focuses on comparing the effects of home-based (HB) and group-based (GB) physical activity on mental health in a sample of older adults in Shahr-e-kord. In this quasi-experimental study, a twice-weekly physical activity program for 2 months was provided either individually at home or in a group format for 181 people who were divided into two groups (HB and GB). The outcome, mental health, was measured with the 28-item General Health Questionnaire (GHQ-28). Mental health status improved after participation in the physical activity program. The decrease in GHQ-28 total score in GB group, 3 months after intervention, was 3.61 ± 2.28 (P effects of GB physical activity on mental health compared with HB physical activity, adjusted for related baseline variables, were significant. These findings reveal the probable effects of GB rather than HB physical activity on mental health among the elderly.

Effective exercise interventions are needed to improve quality of life and decrease the impact of chronic disease. Researchers suggest males have been underrepresented in exercise intervention studies, resulting in less understanding of their exercise practices. Findings from preference survey methods suggest reasonable association between preference and behavior. The purpose of the research described in this article was to use factorial survey, a preference method, to identify the characteristics of exercise interventions most likely to appeal to male participants, so preferences might be incorporated into future intervention research. The research was guided by the framework of Bandura's social cognitive theory, such that variations in individual, environmental, and behavioral factors were incorporated into vignettes. Participants included 53 adult male nonadministrative staff and contract employees at a public university in the Southeastern United States, who each scored 8 vignettes resulting in 423 observations. Multilevel models were used to assess the influence of the factors. Participants scored vignettes that included exercising with a single partner, playing basketball, and exercising in the evening higher than vignettes with other options. Qualitative analysis of an open response item identified additional alternatives in group size, participant desire for coaching support, and interest in programs that incorporate a range of activity alternatives. Findings from this research were consistent with elements of social cognitive theory as applied to health promotion. Factorial surveys potentially provide a resource effective means of identifying participants' preferences for use when planning interventions. The addition of a single qualitative item helped clarify and expand findings from statistical analysis.

Modeling Perceptual Grouping and Figure-Ground Segregation by Means of Active Reentrant Connections

1991-01-01

The segmentation of visual scenes is a fundamental process of early vision, but the underlying neural mechanisms are still largely unknown. Theoretical considerations as well as neurophysiological findings point to the importance in such processes of temporal correlations in neuronal activity. In a previous model, we showed that reentrant signaling among rhythmically active neuronal groups can correlate responses along spatially extended contours. We now have modified and extended this model to address the problems of perceptual grouping and figure-ground segregation in vision. A novel feature is that the efficacy of the connections is allowed to change on a fast time scale. This results in active reentrant connections that amplify the correlations among neuronal groups. The responses of the model are able to link the elements corresponding to a coherent figure and to segregate them from the background or from another figure in a way that is consistent with the so-called Gestalt laws.

Phenomenon: Medical student perspectives were sought about active learning, including concerns, challenges, perceived advantages and disadvantages, and appropriate role in the educational process. Focus groups were conducted with students from all years and campuses of a large U.S. state medical school. Students had considerable experience with active learning prior to medical school and conveyed accurate understanding of the concept and its major strategies. They appreciated the potential of active learning to deepen and broaden learning and its value for long-term professional development but had significant concerns about the efficiency of the process, the clarity of expectations provided, and the importance of receiving preparatory materials. Most significantly, active learning experiences were perceived as disconnected from grading and even as impeding preparation for school and national examinations. Insights: Medical students understand the concepts of active learning and have considerable experience in several formats prior to medical school. They are generally supportive of active learning concepts but frustrated by perceived inefficiencies and lack of contribution to the urgencies of achieving optimal grades and passing United States Medical Licensing Examinations, especially Step 1.

The first human case of tularemia in Iran was reported in 1980 and there have been no subsequent reports of tularemia in the country. The aim of this study was to carry out a survey of tularemia among different groups in the province of Kurdistan in western Iran. The following information was collected by means of an in-house questionnaire: participant demographic characteristics, exposure to risks, and use of appropriate personal protective equipment and disinfectant in their occupation. A blood sample was collected from each participant. Sera were tested using an ELISA kit (Virion\\Serion) to detect specific IgG antibodies against Francisella tularensis. Of a total of 250 serum samples, 14.40% had anti-tularemia IgG antibodies. The highest seroprevalence was found in hunters (18%) and the lowest in health care workers (12%). Age had a significant positive association with tularemia seroprevalence (ptularemia in people exposed to foxes (hunting or eating the meat) (25%) was significantly higher than in others (8.65%) (p = 0.01). According to the findings of this study, it is highly recommended that physicians and health care workers are informed about bacteria circulating in this area. By sensitizing the health system, it is expected that some cases of the clinical disease will be reported in the near future. Similar studies in other parts of the country and on domestic and wild animals will clarify the epidemiology of tularemia in Iran. Copyright © 2013 The Authors. Published by Elsevier Ltd..

In this study, the authors compared differences in sexual risk attitudes and intentions for three groups of youth (experimental program, n = 90; attention control, n = 80; and nonparticipant control, n = 634) aged 12-14 years. Two student groups participated with their parents in programs focused on strengthening family interaction and prevention of sexual risks, HIV, and adolescent pregnancy. Surveys assessed students' attitudes and intentions regarding early sexual and other health-risk behaviors, family interactions, and perceived parental disapproval of risk behaviors. The authors used general linear modeling to compare results. The experimental prevention program differentiated the total scores of the 3 groups (p < .05). A similar result was obtained for student intentions to avoid sex (p < .01). Pairwise comparisons showed the experimental program group scored higher than the nonparticipant group on total scores (p < .01) and on students' intention to avoid sex (p < .01). The results suggest this novel educational program involving both parents and students offers a promising approach to HIV and teen pregnancy prevention.

Epidemiological surveys on the effects of low-level radiation dose: a comparative assessment. Vol. A: pre-conception irradiation effects. Vol. E (DRAFT A): group collation tables

In this report, the health effects of low-level doses of radiation are considered by reference to published epidemiological surveys. The work was carried out with three objectives in mind: 1. to provide a comprehensive and critical review of the subject; 2. to seek consistent indications of particular health effects by collating results and comparing with those from surveys at moderate-level doses; 3. to provide an authoritative view on the epidemiology of low-level radiation-induced health effects. Vol E (DRAFT A) is appended and contains group collation tables. Epidemiological surveys can be conveniently divided into four classes (A, B, C, D) according to the phase of life when irradiation occurs or the effect is diagnosed. The first of the classes (A) is addressed here; this class is concerned with possible effects arising from radiation received by a parent before conception. Possible effects of preconception irradiation were identified under four broad groupings. These are Down's syndrome, ''Indicators of Reproductive Damage'' (mainly Primary Sterility, Congenital Abnormalities, Sex Ratio, Fetal Mortality, Infant Mortality), Childhood Malignancies, and Chromosomal Changes in Abortuses. Information about each survey, and comparisons with results from moderate-level dose surveys, are contained in synopses that are set out in the Appendix.

Extensive recruitment effort at baseline increases representativeness of study populations by decreasing non-response and associated bias. First, it is not known to what extent increased attrition occurs during subsequent measurement waves among subjects who were hard-to-recruit at baseline and what characteristics the hard-to-recruit dropouts have compared to the hard-to-recruit retainers. Second, it is unknown whether characteristics of hard-to-recruit responders in a prospective population based cohort study are similar across age group and survey method. First, we compared first wave (T1) easy-to-recruit with hard-to-recruit responders of the TRacking Adolescents' Individual Lives Survey (TRAILS), a prospective population based cohort study of Dutch (pre)adolescents (at first wave: n = 2230, mean age = 11.09 (SD 0.56), 50.8% girls), with regard to response rates at subsequent measurement waves. Second, easy-to-recruit and hard-to-recruit participants at the fourth TRAILS measurement wave (n = 1881, mean age = 19.1 (SD 0.60), 52.3% girls) were compared with fourth wave non-responders and earlier stage drop-outs on family composition, socioeconomic position (SEP), intelligence (IQ), education, sociometric status, substance use, and psychopathology. First, over 60% of the hard-to-recruit responders at the first wave were retained in the sample eight years later at the fourth measurement wave. Hard-to-recruit dropouts did not differ from hard-to-recruit retainers. Second, extensive recruitment efforts for the web based survey convinced a population of nineteen year olds with similar characteristics as the hard-to-recruit eleven year olds that were persuaded to participate in a school-based survey. Some characteristics associated with being hard-to-recruit (as compared to being easy-to-recruit) were more pronounced among non-responders, resembling the baseline situation (De Winter et al.2005). First, extensive recruitment effort at the first

PURPOSE. This study compares a traditional worksite-based health promotion program with an activated consumer program and a control program DESIGN. Group randomized controlled trial with 18-month intervention. SETTING. Two large Midwestern companies. SUBJECTS. Three hundred and twenty employees (51% response). INTERVENTION. The traditional health promotion intervention offered population-level campaigns on physical activity, nutrition, and stress management. The activated consumer intervention included population-level campaigns for evaluating health information, choosing a health benefits plan, and understanding the risks of not taking medications as prescribed. The personal development intervention (control group) offered information on hobbies. The interventions also offered individual-level coaching for high risk individuals in both active intervention groups. MEASURES. Health risk status, general health status, consumer activation, productivity, and the ability to evaluate health information. ANALYSIS. Multivariate analyses controlled for baseline differences among the study groups. RESULTS. At the population level, compared with baseline performance, the traditional health promotion intervention improved health risk status, consumer activation, and the ability to recognize reliable health websites. Compared with baseline performance, the activated consumer intervention improved consumer activation, productivity, and the ability to recognize reliable health websites. At the population level, however, only the activated consumer intervention improved any outcome more than the control group did; that outcome was consumer activation. At the individual level for high risk individuals, both traditional health coaching and activated consumer coaching positively affected health risk status and consumer activation. In addition, both coaching interventions improved participant ability to recognize a reliable health website. Consumer activation coaching also

Most physiological and environmental changes are capable of inducing variations in animal behavior. The behavioral parameters have the possibility to be measured continuously in-situ by a non-invasive and non-contact approach, and have the potential to be used in the actual productions to predict stress conditions. Most vertebrates tend to live in groups, herds, flocks, shoals, bands, packs of conspecific individuals. Under culture conditions, the livestock or fish are in groups and interact on each other, so the aggregate behavior of the group should be studied rather than that of individuals. This paper presents a method to calculate the movement speed of a group of animal in a enclosure or a tank denoted by body length speed that correspond to group activity using computer vision technique. Frame sequences captured at special time interval were subtracted in pairs after image segmentation and identification. By labeling components caused by object movement in difference frame, the projected area caused by the movement of every object in the capture interval was calculated; this projected area was divided by the projected area of every object in the later frame to get body length moving distance of each object, and further could obtain the relative body length speed. The average speed of all object can well respond to the activity of the group. The group activity of a tilapia (Oreochromis niloticus) school to high (2.65 mg/L) levels of unionized ammonia (UIA) concentration were quantified based on these methods. High UIA level condition elicited a marked increase in school activity at the first hour (P<0.05) exhibiting an avoidance reaction (trying to flee from high UIA condition), and then decreased gradually.

Full Text Available : Starting from the assumption that motor activities are the perfect environment for socialization, communication and social integration of young people, this study aims to analyze the effectiveness of these activities in improving intergroup relations at the university level. In this research, the samples were composed of two groups, the experimental group (n = 25 with students from the Physical Education specialization and control group B (n = 25, composed of students from the Faculty of Sciences. The sociological survey applied on the two samples aimed to analyze the level of socialization, communication and social integration of students. The findings showed that the experimental group is more united, having a higher level of socialization and communication, compared to the control group B, proving once again the socializing effects of motor activities.

Are Immigrants More Physically Active Than Native-Born Australians and Does it Changes Over Time? Evidence From a Nationally Representative Longitudinal Survey.

We investigated the differences and over time changes in recommended physical activity among foreign-born (FB) from English speaking countries (ESC) and non-English speaking countries (NESC) relative to native-born (NB) Australians, and whether the association between nativity and duration of residence (DoR) and physical activity is mediated by English language proficiency, socioeconomic status and social engagement/membership. This study applies multilevel group-meancentered mixed (hybrid) logistic regression models to 12 waves of longitudinal data (12,634 individuals) from the Household, Income and Labor Dynamics in Australia survey with engagement in physical activities for more than 3 times a week as the outcome variable. Immigrants from ESC had higher odds of physical activity, while immigrants from NESC had significantly lower odds of physical activity than NB Australians, after adjusting for covariates. There was no evidence that these differences changed by DoR among immigrants from NESC, whereas ESC immigrants had higher odds of physical activity when their DoR was more than 20 years. We also found a mediating role of English language proficiency on immigrants physical activities. Appropriate health promotion interventions should be implemented to foster physical activities among NESC immigrants, considering English language proficiency as an important factor in designing interventions.
