    Recent research has emphasised that the challenge in researching socioeconomic differences in adolescent health cross-nationally lies in providing valid and comparable measures of socioeconomic position (SEP) across regions. This study aims to examine measures of occupational status derived from the International Standard Classification of Occupations (ISCO), alongside commonly used affluence measures in association with adolescent self-rated health (SRH). Data were from the 2005/2006 'Health Behaviour in School-aged Children study' (HBSC); 27 649 individuals aged 11, 13 and 15 years from Germany, Macedonia, Norway, Turkey, Wales and Scotland. Three occupational scales were compared: the International Socioeconomic Index of Occupational Status (ISEI), the Standard International Occupational Prestige Scale (SIOPS) and the Erikson-Goldthorpe-Portocarero class categories (EGP). Correlation analyses compared these occupational scales with the family affluence scale (FAS) and a family well-off measure, while logistic regression assessed the association between occupational scales and poor SRH. Multiple imputation techniques investigated possible bias arising from parental occupation missingness. Moderate correlations existed between occupational scales and FAS and family well-off. Socioeconomic inequalities in poor SRH were found for ISEI, SIOPS and EGP in all regions, independent of FAS and family well-off. Models of imputed data sets did not alter the results. The relationship between SEP and SRH was therefore not biased by high levels of missing values for ISCO. ISCO-based indicators of occupational status in cross-national self-administered adolescent health surveys were found to be robust measures of SEP in adolescence. These measure different aspects of SEP independent of FAS and family well-off. Published by the BMJ Publishing Group Limited.

    Full Text Available Introduction & Objective: Hexavalent chromium, Cr+6, is a very harmful pollutant and a relatively unstable compound that is present in many industries. It is a known human respiratory carcinogen and occupational exposure to this chemical is associated with different health hazards. The purpose of this study was to evaluate the effects of four parameters including: type of sampling head, sampling height from the surface of electroplating solution, sampling duration, and sample storage duration on Cr+6 mist monitoring.Materials & Methods: To evaluate the influence of the main parameters as an experimental study, the 24 factorial design was applied at constant electroplating condition. A chromium electroplating bath with the ability to produce homogenous mist was used to create Cr+6 mist in laboratory setting. The National Institute for Occupational Safety and Health (NIOSH method 7600 was used to determine the Cr+6 concentration. Results: The results of 48 Cr+6 mist samples showed that Cr+6 concentration was higher: (1 for sampling by closed-face filter cassettes than for sampling by open-face filter cassettes (P<0.001; (2 for samples collected at 35 cm above the electroplating solution surface than for samples collected at 50 cm (P <0.001; (3 for sampling duration of 30 minutes than for sampling duration of 180 minutes (P <0.001; and, (4 for samples extracted immediately after sampling than for samples with delayed extraction (24 hours after sampling (P <0.001. Conclusion: It is concluded that the accuracy of Cr+6 mist sampling in electroplating shops will be enhanced when: (1 a closed-face filter cassette is used to prevent liquid splash contamination; (2 the sampling height is suitable as determined by further research; (3 the sampling duration is short (approximately 30 minutes; and, (4 the extraction of the Cr+6 sample is performed as soon as the sampling is completed.

  5. The 1986 residential occupant survey

    1987-04-01

    In 1986, Pacific Northwest Laboratory developed the Residential Occupant Survey-Spring '86, which was implemented. The overall purpose of the study was to collect demographic, attitudinal, and behavioral data related to the use and conservation of electricity in dwellings participating in the Bonneville Power Administration's End-Use Load and Conservation Assessment Program (ELCAP). Information was collected on the respondents' perceptions of the energy efficiency of their dwelling, temperature the dwelling was kept when people were at home and awake during the last heating season, which rooms, if any, were not heated during the last heating season, number of times the dwelling was unoccupied for at least one week, number of times pets were let out of the dwelling per day, attitudes toward energy use and conservation and several socio-demographic variables such as age, sex, and total household income. The results of the data analyses showed age to be an important factor for reported indoor temperature and perceived energy efficiency of the dwelling. The results also showed that almost 60% of the ELCAP occupants do not heat one or more rooms during the heating season, and almost 45% of the ELCAP dwellings were unoccupied for at least one week during the reporting period. In terms of the reported allocation of household income for household energy expenses, the results showed that the reported dollar amount spent for the expenses remained relatively constant over income levels.

    Site occupancy is an extremely important aspect of quantification of protein modifications. Knowing the degree of modification of each oxidised cysteine residue is critical to understanding the biological role of these modifications. Yet modification site occupancy is very often overlooked, in part...... occupancy of the modification site. We show that, on one hand, heavily modified cysteines are not necessarily involved in the response to oxidative stress. On the other hand residues with low modification level can be dramatically affected by mild oxidative imbalance. We make use of high resolution mass...... peptides corresponding to 90 proteins. Only 6 modified peptides changed significantly under mild oxidative stress. Quantitative information allowed us to determine relative modification site occupancy of each identified modified residue and pin point heavily modified ones. The method proved to be precise...

  7. Multiseason occupancy models for correlated replicate surveys

    Hines, James; Nichols, James; Collazo, Jaime

    2014-01-01

    Occupancy surveys collecting data from adjacent (sometimes correlated) spatial replicates have become relatively popular for logistical reasons. Hines et al. (2010) presented one approach to modelling such data for single-season occupancy surveys. Here, we present a multiseason analogue of this model (with corresponding software) for inferences about occupancy dynamics. We include a new parameter to deal with the uncertainty associated with the first spatial replicate for both single-season and multiseason models. We use a case study, based on the brown-headed nuthatch, to assess the need for these models when analysing data from the North American Breeding Bird Survey (BBS), and we test various hypotheses about occupancy dynamics for this species in the south-eastern United States. The new model permits inference about local probabilities of extinction, colonization and occupancy for sampling conducted over multiple seasons. The model performs adequately, based on a small simulation study and on results of the case study analysis. The new model incorporating correlated replicates was strongly favoured by model selection for the BBS data for brown-headed nuthatch (Sitta pusilla). Latitude was found to be an important source of variation in local colonization and occupancy probabilities for brown-headed nuthatch, with both probabilities being higher near the centre of the species range, as opposed to more northern and southern areas. We recommend this new occupancy model for detection–nondetection studies that use potentially correlated replicates.

    Full Text Available Abstract Background Occupational health has received limited research attention in the Southern African Development Community (SADC. Much of the published data in this region come from South Africa and little has been reported north of the Limpopo. The present study was conducted to estimate the burden of occupational illnesses in Zambia and assess factors associated with their occurrence. Methods Data were obtained from the Zambian Labour Force Survey of 2009. Frequencies were used to estimate the prevalence of occupational diseases. Logistic regression analyses were conducted to determine the associations between demographic, social and economic factors and reported illness resulting from occupational exposures. Odds ratios (OR from bivariate analyses and adjusted odds ratios (AOR from the multivariate analysis together with their 95% Confidence Intervals (CI are reported. Results Data on 59,118 persons aged 18 years or older were available for analysis, of which 29805 (50.4% were males. The proportions of the sample that reported to have suffered from an occupational illness were 12.7% among males and 10.4% among females (p Conclusions The findings from this study call for urgent effort for specific measures to prevent and mitigate the effects of occupational injuries. These interventions may include: public health campaigns, enforcement or change in work policies and regulations. Special attention may have to be made towards those who were more likely to suffer from occupational illnesses.

    2011-07-01

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

    Access to occupational health services for primary prevention and control of work-related injuries and illnesses by the global workforce is limited (World Health Organization [WHO], 2013). From the WHO survey of 121 (61%) participating countries, only one-third of the responding countries provided occupational health services to more than 30% of their workers (2013). How services are provided in these countries is dependent on legal requirements and regulations, population, workforce characteristics, and culture, as well as an understanding of the impact of workplace hazards and worker health needs. Around the world, many occupational health services are provided by occupational health nurses independently or in collaboration with other disciplines' professionals. These services may be health protection, health promotion, or both, and are designed to reduce health risks, support productivity, improve workers' quality of life, and be cost-effective. Rantanen (2004) stated that basic occupational health services must increase rather than decline, especially as work becomes more complex; workforces become more dynamic and mobile, creating new models of work-places; and jobs become more precarious and temporary. To better understand occupational health services provided by occupational health nurses globally and how decisions are made to provide these services, this study examined the scope of services provided by a sample of participating occupational health nurses from various countries.

    Surveys to detect the presence or absence of endangered species may not consistently cover an area, account for imperfect detection or consider that detection and species presence at sample units may change within a survey season. We evaluated a detection?nondetection survey method for the federally endangered golden-cheeked warbler (GCWA) Dendroica chrysoparia. Three study areas were selected across the breeding range of GCWA in central Texas. Within each area, 28-36 detection stations were placed 200 m apart. Each detection station was surveyed nine times during the breeding season in 2 consecutive years. Surveyors remained up to 8 min at each detection station recording GCWA detected by sight or sound. To assess the potential influence of environmental covariates (e.g. slope, aspect, canopy cover, study area) on detection and occupancy and possible changes in occupancy and detection probabilities within breeding seasons, 30 models were analyzed. Using information-theoretic model selection procedures, we found that detection probabilities and occupancy varied among study areas and within breeding seasons. Detection probabilities ranged from 0.20 to 0.80 and occupancy ranged from 0.56 to 0.95. Because study areas with high detection probabilities had high occupancy, a conservative survey effort (erred towards too much surveying) was estimated using the lowest detection probability. We determined that nine surveys of 35 stations were needed to have estimates of occupancy with coefficients of variation <20%. Our survey evaluation evidently captured the key environmental variable that influenced bird detection (GCWA density) and accommodated the changes in GCWA distribution throughout the breeding season.

    Accurate estimates of the distribution and abundance of endangered species are crucial to determine their status and plan recovery options, but such estimates are often difficult to obtain for species with low detection probabilities or that occur in inaccessible habitats. The Puaiohi (Myadestes palmeri) is a cryptic species endemic to Kauaʻi, Hawai‘i, and restricted to high elevation ravines that are largely inaccessible. To improve current population estimates, we developed an approach to model distribution and abundance of Puaiohi across their range by linking occupancy surveys to habitat characteristics, territory density, and landscape attributes. Occupancy per station ranged from 0.17 to 0.82, and was best predicted by the number and vertical extent of cliffs, cliff slope, stream width, and elevation. To link occupancy estimates with abundance, we used territory mapping data to estimate the average number of territories per survey station (0.44 and 0.66 territories per station in low and high occupancy streams, respectively), and the average number of individuals per territory (1.9). We then modeled Puaiohi occupancy as a function of two remote-sensed measures of habitat (stream sinuosity and elevation) to predict occupancy across its entire range. We combined predicted occupancy with estimates of birds per station to produce a global population estimate of 494 (95% CI 414–580) individuals. Our approach is a model for using multiple independent sources of information to accurately track population trends, and we discuss future directions for modeling abundance of this, and other, rare species.

    There is an increasing demand for rehabilitation services in China as a result of the growing number of people with physical and mental challenges, as well as the growing population of older adults. The purpose of this study was to explore the current occupational therapy (OT) resources available in Beijing, China, to serve as the first step in planning the response to increasing demand for OT services from the people of China. Specifically, using the snowball sampling survey method, we explored the work practice, including years of working experience, work setting, weekly work hours, annual income and factors related to job satisfaction among occupational therapists in Beijing, China. A total of 44 occupational therapists currently working in the Beijing area responded to our survey. The results demonstrated that most of the therapists working in Beijing area were young and inexperienced. Despite the fact that the participants had an average age of 31 years old and an average of 8 years' working experience, 61.4% of therapists were under 30 years old and more than half of therapists had less than 5 years of OT experiences. Among those included in the study sample, 50% had earned degrees in OT, and the rest of the OT personnel received OT-related on-the-job training in various forms and lengths of time. A majority of the participants worked in hospital settings with adults or children with physical disabilities and used therapeutic activities and therapeutic exercises. Being an occupational therapist is not a high-paying job. Education satisfaction, work experience and annual income are the factors related to job satisfaction for the participants. The majority of occupational therapists expressed the need to receive more support for clinical-related trainings. We plan to expand this pilot study nationwide to gain an in-depth and comprehensive understanding of the OT workforce in China. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley

    The present work is dedicated to the study of occupational cold environments in food distribution industrial units. Field measurements and a subjective assessment based on an individual questionnaire were considered. The survey was carried out in 5 Portuguese companies. The field measurements include 26 workplaces, while a sample of 160 responses was considered for the subjective assessment. In order to characterize the level of cold exposure, the Required Clothing Insulation Index (IREQ) was adopted. The IREQ index highlights that in the majority of the workplaces the clothing ensembles worn are inadequate, namely in the freezing chambers where the protection provided by clothing is always insufficient. The questionnaires results show that the food distribution sector is characterized by a female population (70.6%), by a young work force (60.7% are less than 35 yr old) and by a population with a medium-length professional career (80.1% in this occupation for less than 10 yr). The incidence of health effects which is higher among women, the distribution of protective clothing (50.0% of the workers indicate one garment) and the significant percentage of workers (>75%) that has more difficulties in performing the activity during the winter represent other important results of the present study.

    Forest-dwelling raptors are often difficult to detect because many species occur at low density or are secretive. Broadcasting conspecific vocalizations can increase the probability of detecting forest-dwelling raptors and has been shown to be an effective method for locating raptors and assessing their relative abundance. Recent advances in statistical techniques based on presence-absence data use probabilistic arguments to derive probability of detection when it is <1 and to provide a model and likelihood-based method for estimating proportion of sites occupied. We used these maximum-likelihood models with data from red-shouldered hawk (Buteo lineatus) call-broadcast surveys conducted in central Minnesota, USA, in 1994-1995 and 2004-2005. Our objectives were to obtain estimates of occupancy and detection probability 1) over multiple sampling seasons (yr), 2) incorporating within-season time-specific detection probabilities, 3) with call type and breeding stage included as covariates in models of probability of detection, and 4) with different sampling strategies. We visited individual survey locations 2-9 times per year, and estimates of both probability of detection (range = 0.28-0.54) and site occupancy (range = 0.81-0.97) varied among years. Detection probability was affected by inclusion of a within-season time-specific covariate, call type, and breeding stage. In 2004 and 2005 we used survey results to assess the effect that number of sample locations, double sampling, and discontinued sampling had on parameter estimates. We found that estimates of probability of detection and proportion of sites occupied were similar across different sampling strategies, and we suggest ways to reduce sampling effort in a monitoring program.

    Full Text Available Background: Existence of coordinated and professional safety system to prevent occurrence of accidents and potential hazards seem to be essential in installing networks of gas distribution projects. Objective: To survey work-related accidents and safety performance indices in project implementation unit of Yazd gas agency. Methods: This analytical study was conducted on 197 of workforce in Yazd gas agency in 2013 that were selected by census and they were male. Demographic and accident information were gathered using a self-made questionnaire and face- to- face interview, and required information obtained from dossier to determine the safety performance indicators. Safety performance indicators were calculated in separately of 13 types occupations in project implementation unit of gas agency and data were analyzed using T-test. Findings: The highest accident frequency and severity rate were related to digging occupation and then metal line welding. Consequences of accidents were cuts (%56.7 and soreness (%14.9. The causes of accidents were related to uselessness of personal protective equipment (%25.2 and lack of precision in the task (%19.3. The highest rate of accident was observed among the age group 20-29 years with work experience of 4-6 years. Conclusion: According to the findings of this study and the risk of gas processes, it seems to be necessary the implementation of integrated management systems and training of workers about safety rules to improve the safety culture and prevent accidents.

    Taormina, Deborah; Burgel, Barbara J

    2013-02-01

    The Institute of Medicine (2011) report Occupational Health Nurses and Respiratory Protection: Improving Education and Training outlined seven recommendations to improve the competency of occupational health nurses in respiratory protection. An advisory group was convened in December 2011, with stakeholder representation from the Centers for Disease Control and Prevention/National Institute for Occupational Safety and Health/National Personal Protective Technology Laboratory, American Association of Occupational Health Nurses, Inc., American Board for Occupational Health Nurses, Inc., Association of Occupational Health Professionals in Healthcare, American Nurses Association, and Institute of Medicine Standing Committee on Personal Protective Equipment for Workplace Safety and Health. The initial work of the advisory group included developing and administering a survey to assess current occupational health nurse roles and responsibilities relevant to respiratory protection. Development of the survey was led by a master's student and advisor who worked with the advisory group. The process of tool development and preliminary findings are presented in this article.

    Occupational asthma commonly results in work-related changes in serial peak expiratory flow (PEF) measurements. Whether alveolitis can result in similar changes is unknown. To identify differences and similarities of serial PEF between workers with occupational alveolitis and asthma seen during an outbreak investigation in a factory with metal-working fluid exposure. Workers with respiratory symptoms and rest-day improvement were identified by questionnaire. Each was asked to measure PEF 8 times daily for 4 weeks at home and work. Alveolitis was subsequently diagnosed from a validated scoring system including radiological changes, carbon monoxide diffusing capacity, bronchoalveolar lavage and biopsy results. Occupational asthma was confirmed with a positive Oasys score >2.5 and a mean rest-work PEF >16 l/min from serial 2-hourly PEF measurements. The Oasys PEF plotter calculated differences between rest and workdays for mean PEF, diurnal variation and the scores were used to confirm an occupational effect (Oasys, area between curve and time point). Records were compared between the alveolitis group and the group with occupational asthma without alveolitis. Forty workers with occupational asthma and 16 with alveolitis had indistinguishable PEF changes on workdays in terms of magnitude (median reduction 18.5 and 16.1 l/min, respectively) and diurnal variation. Immediate reactions were more common with occupational asthma and late reactions more common with alveolitis. PEF responses to metal-working fluid aerosols do not distinguish occupational asthma from alveolitis except in timing. They can be used to identify the workplace as the cause of asthma and also alveolitis. © The Author 2015. Published by Oxford University Press on behalf of the Society of Occupational Medicine.

  15. [Hazard assessment and occupational safety measures in surgery : Relevant knowledge on occupational medicine].

    Science.gov (United States)

    Darius, S; Meyer, F; Böckelmann, I

    2016-11-01

    Surgeons routinely work in an environment with occupational risks and hazards about which they are often uninformed. Based on the currently available scientific literature this review article describes the various hazards in the operating theater and their effects on personnel, particularly from the surgical perspective. A further aim of this article is to describe the occupational safety measures to reduce the burdens and to maintain the long-term health of personnel. Ultimately, surgeons should be equipped with the necessary knowledge for implementing hazard assessments according to the German Occupational Health and Safety Act. Surgeons are exposed to increased risks and hazards by working in awkward positions with a high risk for musculoskeletal pain and injuries. They are also commonly exposed to inhalational anesthetics, surgical smoke, radiation, noise and infectious agents. Furthermore, the mental and emotional stress associated with these activities is also high. Meaningful occupational safety measures for reduction of burdens are from a technical aspect the installation of effective air extraction systems, measures to reduce exposure to radiation and noise and the use of safer instruments to prevent needle stick injuries. Furthermore, individual occupational safety measures, such as the use of personal protective equipment (e.g. radiation protective clothing and double gloves) must be observed. The consistent implementation and also adherence to these described occupational safety measures and regulations can reduce the burden on operating theater personnel and contribute to maintaining health. Furthermore, periodic preventive healthcare controls and health checks by the company medical officer and individually initiated additional prevention measures can be a sensible augmentation to these safety measures.

    Williams, S; Cooper, C L

    1998-10-01

    The study of occupational stress is hindered by the lack of compact and comprehensive standardized measurement tools. The Pressure Management Indicator (PMI) is a 120-item self-report questionnaire developed from the Occupational Stress Indicator (OSI). The PMI is more reliable, more comprehensive, and shorter than the OSI. It provides an integrated measure of the major dimensions of occupational stress. The outcome scales measure job satisfaction, organizational satisfaction, organizational security, organizational commitment, anxiety--depression, resilience, worry, physical symptoms, and exhaustion. The stressor scales cover pressure from workload, relationships, career development, managerial responsibility, personal responsibility, home demands, and daily hassles. The moderator variables measure drive, impatience, control, decision latitude, and the coping strategies of problem focus, life work balance, and social support.

    Full Text Available Background. This study examines how and why occupational therapy practitioners across practice areas use gardening as an intervention. Respondents’ interpretation of the best and least desirable aspects of their facility’s garden and whether they contributed to its design was also examined. Method. A description and link to a 15-question online survey about gardening as an occupational therapy intervention was emailed to Western Michigan University Occupational Therapy alumni and posted on four OT Connections groups and the AOTA LinkedIn site. Results. Gardening as an occupational therapy intervention is meaningful and purposeful (93.66%, n = 56, motivating (80%, n = 48, fun 61.67% (n = 37, and client-centered (31.67%, n =19. Frequency of gardening as a therapeutic intervention and practitioner involvement in designing the garden was significant (p = .007, suggesting that for respondents, environmental context supports engagement and heightens the meaningfulness and purposefulness of gardening. Conclusion. Based on results of this study, a suggested next step is evidence-based translational and intervention research to validate the efficacy of gardening as an occupational therapy intervention and occupational therapy practitioners’ professional value as implementers of such intervention. Assessing the effectiveness of the role of occupational therapy practitioners in facility garden design is also important to consider.

    Full Text Available Objective: To estimate the prevalence of occupational injury disability (OID and to examine the socioeconomic status of OID in China. Methods: The data derived from the China National Sample Survey on Disability in 2006 involving people aged 16–59 years old. Descriptive statistics are used to measure OID’s prevalence, and a binary logistic regression is used to identify the risk factors. Results: The population-weighted prevalence of OID is 1.81 (95% confidence interval (CI: 1.67–1.94. Socioeconomic risk factors include male sex, older age, living in urban areas, junior high school education, income below the poverty line, a lack of occupational injury insurance, living in the western region and working in high-risk occupations. Conclusions: OID is common among Chinese people aged 16–59 years old. Being male or older and having a lower income are risk factors for OID, similar to the results of previous research, but education is different. More training and education needs to be implemented to prevent OID.

  2. Occupational burnout and work factors in community and hospital midwives: a survey analysis.

    2013-08-01

    community-based midwifery practice has been promoted in the UK maternity policy over the last decade as a means of increasing continuity of care. However, there have been growing concerns to suggest that the community-based continuity model may not be sustainable due to the high levels of occupational burnout in midwives resulted by increased on-call work. this paper attempted to identify work factors associated with the levels of burnout in community midwives as compared to hospital midwives, aiming at contributing to the debate of organising sustainable midwifery care. a statistical analysis was conducted drawing on data from a survey of all midwives working at one Hospital Trust in England (n=238). Occupational burnout was measured using the Maslach Burnout Inventory (MBI). the sample midwives (n=128, 54%) had significantly higher levels of burnout compared to the reference groups. Multiple regression analysis identified as follows: (1) high levels of occupational autonomy were a key protective factor of burnout, and more prevalent in the community, (2) working hours were positively associated with burnout, and community midwives were more likely to have higher levels of stress recognition, and (3) support for work-life-balance from the Trust had a significant protective effect on the levels of burnout. the results should be taken into account in the maternity policy in order to incorporate continuity of care and sustainable organisation of midwifery care.

    We present a direct measurement of the mean halo occupation distribution (HOD) of galaxies taken from the eleventh data release (DR11) of the Sloan Digital Sky Survey-III Baryon Oscillation Spectroscopic Survey (BOSS). The HOD of BOSS low-redshift (LOWZ: 0.2 < z < 0.4) and Constant-Mass (CMASS: 0.43 < z < 0.7) galaxies is inferred via their association with the dark matter haloes of 174 X-ray-selected galaxy clusters drawn from the XMM Cluster Survey (XCS). Halo masses are determined for each galaxy cluster based on X-ray temperature measurements, and range between log10(M180/M⊙) = 13 and 15. Our directly measured HODs are consistent with the HOD-model fits inferred via the galaxy-clustering analyses of Parejko et al. for the BOSS LOWZ sample and White et al. for the BOSS CMASS sample. Under the simplifying assumption that the other parameters that describe the HOD hold the values measured by these authors, we have determined a best-fitting alpha-index of 0.91 ± 0.08 and 1.27^{+0.03}_{-0.04} for the CMASS and LOWZ HOD, respectively. These alpha-index values are consistent with those measured by White et al. and Parejko et al. In summary, our study provides independent support for the HOD models assumed during the development of the BOSS mock-galaxy catalogues that have subsequently been used to derive BOSS cosmological constraints.

    2014-03-01

    Full Text Available Occupation is key in socioeconomic research. As in other survey modes, most web surveys use an open-ended question for occupation, though the absence of interviewers elicits unidentifiable or aggregated responses. Unlike other modes, web surveys can use a search tree with an occupation database. They are hardly ever used, but this may change due to technical advancements. This article evaluates a three-step search tree with 1,700 occupational titles, used in the 2010 multilingual WageIndicator web survey for UK, Belgium and Netherlands (22,990 observations. Dropout rates are high; in Step 1 due to unemployed respondents judging the question not to be adequate, and in Step 3 due to search tree item length. Median response times are substantial due to search tree item length, dropout in the next step and invalid occupations ticked. Overall the validity of the occupation data is rather good, 1.7-7.5% of the respondents completing the search tree have ticked an invalid occupation.

    A radiation survey of seven archaeological sites within Egyptian pyramids and tombs has been conducted in the Saggara area. Measurements were made of radon ({sup 222}Rn) and its short-lived decay products (progeny), as well as thoron ({sup 220}Rn) progeny and {gamma}-radiation. The results of these measurements have been used to calculate the maximum annual effective dose (MAD) and other important occupational radiation exposure variables. It was found that for the limited time to which occupational workers and visitors were exposed, their respective MAD values were lower than that recommended by the regulatory agency (i.e., 20 mSv per year for occupational workers and 1 mSv in a year for the public). However, it is shown that if the exposure times for occupational workers were to increase to 'normal' working schedules their MAD would be exceeded at three archaeological sites. Implementation of improved ventilation practices is recommended in those sites to reduce the exposure to occupational workers were their working schedules to be significantly increased. It is also recommended that further monitoring be conducted in the future to verify these results.

    Full Text Available Objectives: Occupational medicine is a discipline continually evolving in response to technological advances, changes in workplaces and production processes, emergence of new occupational risks and diseases and modifications in regulatory framework for occupational health and safety. Therefore, the recurrent revaluation of professional activity, information demands and education and training needs of occupational physicians is essential in order to identify methodologies and tools that may contribute to improvement of their professional knowledge and competency. In this regard, we conducted the first large-scale national survey of Italian occupational medicine physicians to define their demographic and professional activity and to assess their information demands, training and updating needs. Material and Methods: A random sample of occupational physicians, listed in the national register of the Italian Ministry of Health, was selected to complete a voluntary survey. Subjects recruited in this study were asked to complete 3 different sections (personal and professional information, training and updating needs, professional activity and practice characteristics of a questionnaire for a total of 35 questions. Results: Most of participants were specialized in occupational medicine, worked for a large number of companies and carried out health surveillance on a total number of workers that exceeds 1500. Occupational physicians would like to have a higher training offer towards practical aspects of health surveillance, risks assessment, manual handling of loads, chemical substances and upper limb biomechanical overload. Interestingly, statistically significant differences were observed subdividing the sample into different groups according to the legal requirements to perform the professional activity of occupational physicians in Italy or according to particular aspects of their professional activity. Conclusions: This study has provided interesting

    2008-01-01

    This study describes how occupational therapists who reported using the Model of Human Occupation (MOHO) actually use the concepts and tools of this model in everyday practice as well as identifies supports and barriers to its use. A systematic random sample of 1,000 occupational therapists was surveyed as to what theories they used in their practice. Those using MOHO (430) were sent a detailed questionnaire; 259 therapists (60.2%) responded to the survey questionnaire. More than 80% of respondents indicated that they used MOHO in their practice at least some of the time. Therapists reported that MOHO supports holistic, occupation-focused, client-centered, and evidence-based practice. They reported finding MOHO concepts useful for treatment planning and intervention. Most saw the major barrier to using MOHO as their own lack of knowledge. Making resources more readily available and accessible to therapists might enhance the extent to which they use conceptual models such as MOHO.

    Upper extremity hemiparesis is an impairment post-stroke that impacts quality of life. Home programs are an intervention strategy used by many occupational therapists to support continued motor recovery post-stroke, yet little is known about how these programs are designed and implemented. The purpose of this study was to describe how occupational therapy practitioners approach this task and specifically what strategies they use to support adherence and what types of technology are most commonly used. An on-line survey methodology was used. Participants were recruited through multiple sources including state associations and occupational therapy educational program directors. A total of 73 occupational therapy practitioners submitted complete surveys. It was found that majority of occupational therapy practitioners in the sample (n = 53) reported creating home programs focused on upper extremity motor recovery more than 80% of the time. Range of motion and strengthening were reported as being in the top three most commonly used interventions by more than half the sample, however incorporating clients' goals and interests were reported most often as strategies to create meaning in the home program. Respondents also reported limited incorporation of technology and strategies to support adherence. Personal motivation was reported by occupational therapy practitioners to be a key moderator of adherence to a home program. Occupational therapy practitioners often provide home programs for individuals post-stroke focusing on upper extremity function. Future research that aims to understand stakeholders' perspectives on home programs and determine effective strategies for ensuring adherence is needed.

    2010-12-01

    Full Text Available No guidelines are available to orient researchers on the availability and applications of equipment and sensors for recording precise neck movements in occupational settings. In this study reports on direct measurements of neck movements in the workplace were reviewed. Using relevant keywords two independent reviewers searched for eligible studies in the following databases: Cinahal, Cochrane, Embase, Lilacs, PubMed, MEDLINE, PEDro, Scopus and Web of Science. After applying the inclusion criteria, 13 articles on direct neck measurements in occupational settings were retrieved from among 33,666 initial titles. These studies were then methodologically evaluated according to their design characteristics, exposure and outcome assessment, and statistical analysis. The results showed that in most of the studies the three axes of neck movement (flexion-extension, lateral flexion and rotation were not simultaneously recorded. Deficiencies in available equipment explain this flaw, demonstrating that sensors and systems need to be improved so that a true understanding of real occupational exposure can be achieved. Further studies are also needed to assess neck movement in those who perform heavy-duty work, such as nurses and electricians, since no report about such jobs was identified.

  17. Multiple distinct stimuli increase measured nucleosome occupancy around human promoters.

    Directory of Open Access Journals (Sweden)

    Chuong D Pham

    Full Text Available Nucleosomes can block access to transcription factors. Thus the precise localization of nucleosomes relative to transcription start sites and other factor binding sites is expected to be a critical component of transcriptional regulation. Recently developed microarray approaches have allowed the rapid mapping of nucleosome positions over hundreds of kilobases (kb of human genomic DNA, although these approaches have not yet been widely used to measure chromatin changes associated with changes in transcription. Here, we use custom tiling microarrays to reveal changes in nucleosome positions and abundance that occur when hormone-bound glucocorticoid receptor (GR binds to sites near target gene promoters in human osteosarcoma cells. The most striking change is an increase in measured nucleosome occupancy at sites spanning ∼1 kb upstream and downstream of transcription start sites, which occurs one hour after addition of hormone, but is lost at 4 hours. Unexpectedly, this increase was seen both on GR-regulated and GR-non-regulated genes. In addition, the human SWI/SNF chromatin remodeling factor (a GR co-activator was found to be important for increased occupancy upon hormone treatment and also for low nucleosome occupancy without hormone. Most surprisingly, similar increases in nucleosome occupancy were also seen on both regulated and non-regulated promoters during differentiation of human myeloid leukemia cells and upon activation of human CD4+ T-cells. These results indicate that dramatic changes in chromatin structure over ∼2 kb of human promoters may occur genomewide and in response to a variety of stimuli, and suggest novel models for transcriptional regulation.

The aim of this study was to examine body mass index (BMI and prevalence of overweight and obesity by occupation and explore the contributions of socioeconomic factors and lifestyle behaviors (including leisure time and commuting physical activity, diet, smoking, and alcohol to occupational risk. Methods Secondary analyses of the National Health Survey in Australia (2005 were conducted for working age adults (20 to 64 years. Linear and logistic regression models using BMI as either dichotomous or continuous response were computed for occupation type. Model 1 was age-adjusted, Model 2 adjusted for age and socioeconomic variables and Model 3 adjusted for age, socioeconomic variables and lifestyle behaviours. All models were stratified by gender. Results Age-adjusted data indicated that men in associate professional (OR 1.34, 95% CI 1.10-1.63 and intermediate production and transport (OR 1.24 95% CI 1.03-1.50 occupations had a higher risk of BMI ≥ 25 kg/m2 than those without occupation, and women in professional (OR 0.71, 95% CI 0.61-0.82, management (OR 0.72, 95% CI 0.56-0.92 and advanced clerical and service occupations (OR 0.73 95% CI 0.58-0.93 had a lower risk. After adjustment for socioeconomic factors no occupational group had an increased risk but for males, professionals, tradesmen, laborers and elementary clerical workers had a lower risk as did female associate professionals and intermediate clerical workers. Adjustment for lifestyle factors explained the lower risk in the female professional and associate professionals but failed to account for the lower odds ratios in the other occupations. Conclusions The pattern of overweight and obesity among occupations differs by gender. Healthy lifestyle behaviors appear to

    Full Text Available Abstract A cross sectional survey was initiated to understand the frequency of occupational injury occurrence and the associated factors in the fish processing industries of western India involving 185 randomly selected women subjects. All the subjects were interviewed with the help of an interviewer-administered questionnaire to collect information regarding their personal, occupational and work related morbidity details (including details of occupational injuries. Logistic regression method was used to analyze the data in order to obtain the contribution of individual factors on occupational injuries. This study has shown that work related morbidity like blanching of hand (OR; 2.30, 95%CI; 1.12–4.74 and nature of job like grading (OR; 3.99, 95%CI; 1.41–11.27 and packing (OR; 5.68, 95%CI; 1.65–19.57 had a significant impact on injury causation. This study eventually concludes that apart from nature of job of fish processing workers occupational hazards prevailing in the work environment contribute significantly to the occurrence of work related injuries and prevention of such occupational hazards may help in protecting workers from occupational injuries also.

    Empirical studies of gender segregation by occupation must be founded on rigorous measurement procedures. There appears to be a consensus that any index used in the analysis of time-series or international cross-section employment data must be either margin-free or decomposable to yield a margin-free component. On the other hand, Charles and Grusky (1995) advocate the use of multiplicative log models from which a margin-free odds ratio can be derived. In this paper, I contrast the construction and interpretation of the index of dissimilarity and the Karmel-MacLachlan index with the multiplicative modeling of gender segregation and the associated log index.

    1. Assessing spatial distributions of threatened large carnivores at landscape scales poses formidable challenges because of their rarity and elusiveness. As a consequence of logistical constraints, investigators typically rely on sign surveys. Most survey methods, however, do not explicitly address the central problem of imperfect detections of animal signs in the field, leading to underestimates of true habitat occupancy and distribution. 2. We assessed habitat occupancy for a tiger Panthera tigris metapopulation across a c. 38 000-km2 landscape in India, employing a spatially replicated survey to explicitly address imperfect detections. Ecological predictions about tiger presence were confronted with sign detection data generated from occupancy sampling of 205 sites, each of 188 km2. 3. A recent occupancy model that considers Markovian dependency among sign detections on spatial replicates performed better than the standard occupancy model (ΔAIC = 184·9). A formulation of this model that fitted the data best showed that density of ungulate prey and levels of human disturbance were key determinants of local tiger presence. Model averaging resulted in a replicate-level detection probability [inline image] = 0·17 (0·17) for signs and a tiger habitat occupancy estimate of [inline image] = 0·665 (0·0857) or 14 076 (1814) km2 of potential habitat of 21 167 km2. In contrast, a traditional presence-versus-absence approach underestimated occupancy by 47%. Maps of probabilities of local site occupancy clearly identified tiger source populations at higher densities and matched observed tiger density variations, suggesting their potential utility for population assessments at landscape scales. 4. Synthesis and applications. Landscape-scale sign surveys can efficiently assess large carnivore spatial distributions and elucidate the factors governing their local presence, provided ecological and observation processes are both explicitly modelled.

    Exposure assessment efforts in population-based studies are increasingly incorporating measurements. The published literature was reviewed to identify the measurement sources and the approaches used to incorporate measurements into these efforts. The variety of occupations and industries in these studies made collecting participant-specific measurements impractical. Thus, the starting point was often the compilation of large databases of measurements from inspections, published literature, and other exposure surveys. These measurements usually represented multiple occupations, industries, and worksites, and spanned multiple decades. Measurements were used both qualitatively and quantitatively, dependent on the coverage and quality of the data. Increasingly, statistical models were used to derive job-, industry-, time period-, and other determinant-specific exposure concentrations. Quantitative measurement-based approaches are increasingly replacing expert judgment, which facilitates the development of quantitative exposure-response associations. Evaluations of potential biases in these measurement sources, and their representativeness of typical exposure situations, warrant additional examination.

    Full Text Available This study investigates whether occupation, variable that reflects social position, is associated with good quality of life among Brazilians. It is a cross-sectional study based on data obtained from a population-based survey carried out in Brazil in 2008. The sample composed of 12,423 Brazilians, older than 20 years. Physical and mental quality of life were both measured by SF-36 and scores were grouped in "above the mean" and "below the mean" to set binary outcomes. Logistic regression analysis was carried out to verify the impact of occupational position on the chances of better physical and mental quality of life, controlling it by socio-demographic and health variables. Results showed that Brazilians included on the labour market have better chances of a good physical and mental quality of life, even if controlled by other variables.

    Technological advances represent opportunities to enhance and supplement traditional fisheries sampling approaches. One example with growing importance for fisheries research is hydroacoustic technologies such as side-scan sonar. Advantages of side-scan sonar over traditional techniques include the ability to sample large areas efficiently and the potential to survey fish without physical handling-important for species of conservation concern, such as endangered sturgeons. Our objectives were to design an efficient survey methodology for sampling Atlantic Sturgeon Acipenser oxyrinchus by using side-scan sonar and to developmethods for analyzing these data. In North Carolina and South Carolina, we surveyed six rivers thought to contain varying abundances of sturgeon by using a combination of side-scan sonar, telemetry, and video cameras (i.e., to sample jumping sturgeon). Lower reaches of each river near the saltwater-freshwater interface were surveyed on three occasions (generally successive days), and we used occupancy modeling to analyze these data.We were able to detect sturgeon in five of six rivers by using these methods. Side-scan sonar was effective in detecting sturgeon, with estimated gear-specific detection probabilities ranging from 0.2 to 0.5 and river-specific occupancy estimates (per 2-km river segment) ranging from 0.0 to 0.8. Future extensions of this occupancy modeling framework will involve the use of side-scan sonar data to assess sturgeon habitat and abundance in different river systems.

Type and frequency of cognition-related problem identification, assessment and intervention use. Respectively, 69%, 83% and 31% of occupational therapists responding to the acute care, inpatient rehabilitation and community-based vignettes recognised cognition as a potential problem. Standardised assessment use was prevalent: 70% working in acute care, 77% in inpatient rehabilitation and 58% in community-based settings indicated using standardised assessments: 81%, 83% and 50%, respectively, indicated using general cognitive interventions. The Mini-Mental State Examination was often used incorrectly to monitor patient change. Executive function, a critical component of post-stroke assessment, was rarely addressed. Interventions were most often general (e.g. incorporated in activities of daily living) rather than specific (e.g. cueing, memory aids, computer-based retraining). © 2011 The Authors.

    Full Text Available Background: Occupational gardeners are exposed to various risk factors like dust, allergens, sharp tools, and pesticides, which make them vulnerable to many diseases. This study was designed to survey the health status of this occupational group. Objectives: The objective was to collect sociodemographic and health status information of occupational gardeners. Materials and Methods: The study group comprised 75 male occupational gardeners of the Bhopal city and suburb. A pretested proforma questionnaire was used to record the necessary information like medical history, sociodemographic factors, and findings of clinical investigations. Result and Discussion: This survey reveals that 50% of gardeners are underweight, 31.99% with high normal to high blood pressure, and none with diabetes. The prevalence of vision disturbance (26.66%, eye inflammation (29.33%, stiff nose (21.33%, joint pain, swelling and muscle stiffness (29.33%, and accidental injury (28% was significantly high among gardeners. Gardeners should be educated to use protective clothing, quit smoking and tobacco consumption, adopt proper body posture, and ensure vaccination.

    Reliable knowledge of the status and trend of carnivore populations is critical to their conservation and management. Methods for monitoring carnivores, however, are challenging to conduct across large spatial scales. In the Northern Rocky Mountains, wildlife managers need a time- and cost-efficient method for monitoring gray wolf (Canis lupus) populations. Montana Fish, Wildlife and Parks (MFWP) conducts annual telephone surveys of >50,000 deer and elk hunters. We explored how survey data on hunters' sightings of wolves could be used to estimate the occupancy and distribution of wolf packs and predict their abundance in Montana for 2007–2009. We assessed model utility by comparing our predictions to MFWP minimum known number of wolf packs. We minimized false positive detections by identifying a patch as occupied if 2–25 wolves were detected by ≥3 hunters. Overall, estimates of the occupancy and distribution of wolf packs were generally consistent with known distributions. Our predictions of the total area occupied increased from 2007 to 2009 and predicted numbers of wolf packs were approximately 1.34–1.46 times the MFWP minimum counts for each year of the survey. Our results indicate that multi-season occupancy models based on public sightings can be used to monitor populations and changes in the spatial distribution of territorial carnivores across large areas where alternative methods may be limited by personnel, time, accessibility, and budget constraints.

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

    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 km(2) 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. For common species with

    Objectives: The purpose of this study is to assess whether recent graduates of the Ohio State University's Occupational Therapy division are applying information-seeking skills they learned as undergraduates, and to seek their advice on ways to improve information-literacy instruction for current and future occupational therapy students. Method: A survey was sent to a sample of graduates from 1995–2000. The results were entered into an SPSS database, and descriptive and inferential results were calculated to determine the information-seeking patterns of these recent graduates. Results: A majority of the occupational therapy graduates who responded to the survey prefer to use information resources that are readily available to them, such as advice from their colleagues or supervisors (79%) and the Internet (69%), rather than the evidence available in the journal literature. Twenty-six percent (26%) of the graduates have searched MEDLINE or CINAHL at least once since they graduated. Formal library instruction sessions were considered useful by 42% of the graduates, and 22% of the graduates found informal contacts with librarians to be useful. Conclusions: Librarians and occupational therapy faculty must intensify their efforts to convey the importance of applying research information to patient care and inform students of ways to access this information after they graduate. In addition to teaching searching skills for MEDLINE and CINAHL, they must provide instruction on how to assess the quality of information they find on the Internet. Other findings suggest that occupational therapy practitioners need access to information systems in the clinical setting that synthesize the research in a way that is readily applicable to patient-care issues.

    Full Text Available Background: Occupation-related health problems are associated with risk or danger as a consequence of the nature of working conditions. Unique working conditions in dentistry can affect the health of dentists. Aim: The aim of this study is to collect information from dentists in Himachal Pradesh concerning common occupation-related health problems, their knowledge and the precautions they commonly took to avoid such problems. Settings and Design: Questionnaire survey conducted on a systematic random sample of 465 dentists among 1395 dentists registered in the state dental council. Materials and Methods: Questionnaires were sent by mail in September 2011 to systematic random sample of 465 dentists. The dentists were asked to complete the questionnaire and return it by mail using the stamped addressed envelope provided. Statistically Analysis Used: The data were analyzed using the software Statistical Package for the Social Sciences version 15 (SPSS Inc., Chicago. Z test was used for statistical comparison. Results: The response rate from the dentists was 81.7%. The most common problem experienced was musculoskeletal pain (46.1% followed by allergic dermatitis of the hands (7.6%. Nearly, all of the respondent dentists wore gloves (100% and face masks (97.4% during work. 1/10 th respondents reported that they had received instructions or training through interactive workshops in occupational health and safety. Conclusions: There seems to be a substantial demand for continuing education on occupational health and safety among dentists in Himachal Pradesh. Hence, more emphasis on occupational health and safety is put into dental training with more continuing education activities on occupational health and safety to practicing dentists.

    We study the applicability of several galaxy environment measures (n^th-nearest-neighbor distance, counts in an aperture, and Voronoi volume) within deep redshift surveys. Mock galaxy catalogs are employed to mimic representative photometric and spectroscopic surveys at high redshift (z ~ 1). We investigate the effects of survey edges, redshift precision, redshift-space distortions, and target selection upon each environment measure. We find that even optimistic photometric redshift errors (\\sigma_z = 0.02) smear out the line-of-sight galaxy distribution irretrievably on small scales; this significantly limits the application of photometric redshift surveys to environment studies. Edges and holes in a survey field dramatically affect the estimation of environment, with the impact of edge effects depending upon the adopted environment measure. These edge effects considerably limit the usefulness of smaller survey fields (e.g. the GOODS fields) for studies of galaxy environment. In even the poorest groups and c...

[Subjects and Methods] The study included into two parts: (1) an investigation of the reliability and validity of the Canadian Occupational Performance Measure for patients with stroke and (2) an exploration of Canadian Occupational Performance Measure results in randomized controlled trials of patients with stroke. For this review, the study searched the MEDLINE, PubMed, and CINAHL Plus with Full Text databases for articles published before September 2015. [Results] Finally, three eligible articles were collected in part 1, and ten randomized controlled trials studies were collected in part 2. The findings of part 1 revealed that the Canadian Occupational Performance Measure had efficient test-retest reliability, however, the Canadian Occupational Performance Measure revealed weak associations with other assessment tools such as Barthel Index used for patients with stroke. Six of the randomized controlled trials studies used the Canadian Occupational Performance Measure as a primary outcome and two as a secondary outcome, while the other two as a goal-setting instrument. [Conclusion] This review indicates that the Canadian Occupational Performance Measure is appropriate for clinicians, including physiotherapists, in assessing outcome for patients with stroke. The Canadian Occupational Performance Measure can assist patients in identifying their outcome performance and provide therapists with directions on interventions.

    ABSTRACT This study was designed to describe multicultural training practices in occupational therapy programs. A survey was sent to occupational therapy programs in the United States to gather information on multicultural content, skills, and teaching methods as well as diversity context and challenges. The response rate was 54%. The most frequently covered multicultural content was related to cultural background and sociopolitical factors. Multicultural skills covered most often were practice oriented and interpersonal skills. Teaching methods reported as used most often differed from the methods thought by the respondents to be most effective. Programs reported multiple challenges to multicultural training including lack of time and lack of diversity in the student body, faculty, and environment. Results suggest that educators may need to expand multicultural content and skills to prepare occupational therapy students for providing care in increasingly diverse practice settings. In addition, increased use of teaching methods that focus on exposure to diverse populations and reflection may be needed to improve the effectiveness of multicultural training in occupational therapy programs.

    Occupational population-based epidemiological data relating to occupational contact allergies in the Chinese clothing industry are limited. To investigate the prevalence of occupational allergic contact dermatitis (OACD) and to identify the causative allergens among clothing employees in China, a cross-sectional study was conducted in 529 clothing employees at 12 clothing factories in Beijing. All employees were subjected to an interview using self-administered questionnaire and skin examination, and those who were diagnosed with occupational contact dermatitis (OCD) were patch tested. In the present survey, we found that the overall 1-year prevalence of OACD among the clothing employees was 8.5%. The 1-year prevalence of OACD among workers (10.8%) was significantly higher than that among managers (3.2%). The lesions were primarily on the hands and wrists in workers, but the face and neck in managers. The major allergens were nickel sulfate and cobalt dichloride in workers and colophony and p-tert-butylphenol formaldehyde resin in managers. In conclusion, workers are at a higher risk of OACD compared with managers in the Chinese clothing industry. In addition to hand dermatitis in workers, airborne contact dermatitis on the face and neck should be also addressed in managers.

    Occupational health and safety management systems apply audit examinations as an integral element of these systems. The examinations are used to verify whether the undertaken actions are in compliance with the accepted regulations, whether they are implemented in a suitable way and whether they are effective. One of the earliest solutions of that type applied in the mining industry in Poland involved the application of audit research based on the MERIT survey (Management Evaluation Regarding Itemized Tendencies). A mathematical model applied in the survey facilitates the determination of assessment indexes WOPi for each of the assessed problem areas, which, among other things, can be used to set up problem area rankings and to determine an aggregate (synthetic) assessment. In the paper presented here, the assessment indexes WOPi were used to calculate a development measure, and the calculation process itself was supplemented with sensitivity analysis.

    Full Text Available Surveys increasingly use mixed mode data collection (e.g., combining face-to-face and web because this controls costs and helps to maintain good response rates. However, a combination of different survey modes in one study, be it cross-sectional or longitudinal, can lead to different kinds of measurement errors. For example, respondents in a face-to-face survey or a web survey may interpret the same question differently, and might give a different answer, just because of the way the question is presented. This effect of survey mode on the question-answer process is called measurement mode effect. This study develops methodological and statistical tools to identify the existence and size of mode effects in a mixed mode survey. In addition, it assesses the size and importance of mode effects in measurement instruments using a specific mixed mode panel survey (Netherlands Kinship Panel Study. Most measurement instruments in the NKPS are multi-item scales, therefore confirmatory factor analysis (CFA will be used as the main analysis tool, using propensity score methods to correct for selection effects.The results show that the NKPS scales by and large have measurement equivalence, but in most cases only partial measurement equivalence. Controlling for respondent differences on demographic variables, and on scale scores from the previous uni-mode measurement occasion, tends to improve measurement equivalence, but not for all scales. The discussion ends with a review of the implications of our results for analyses employing these scales.

    The purpose of this study is to develop and validate a prediction model for identifying employees at increased risk of long-term sickness absence (LTSA), by using variables commonly measured in occupational health surveys. Based on the literature, 15 predictor variables were retrieved from the DAnish National working Environment Survey (DANES) and included in a model predicting incident LTSA (≥4 consecutive weeks) during 1-year follow-up in a sample of 4000 DANES participants. The 15-predictor model was reduced by backward stepwise statistical techniques and then validated in a sample of 2524 DANES participants, not included in the development sample. Identification of employees at increased LTSA risk was investigated by receiver operating characteristic (ROC) analysis; the area-under-the-ROC-curve (AUC) reflected discrimination between employees with and without LTSA during follow-up. The 15-predictor model was reduced to a 9-predictor model including age, gender, education, self-rated health, mental health, prior LTSA, work ability, emotional job demands, and recognition by the management. Discrimination by the 9-predictor model was significant (AUC = 0.68; 95% CI 0.61-0.76), but not practically useful. A prediction model based on occupational health survey variables identified employees with an increased LTSA risk, but should be further developed into a practically useful tool to predict the risk of LTSA in the general working population. Implications for rehabilitation Long-term sickness absence risk predictions would enable healthcare providers to refer high-risk employees to rehabilitation programs aimed at preventing or reducing work disability. A prediction model based on health survey variables discriminates between employees at high and low risk of long-term sickness absence, but discrimination was not practically useful. Health survey variables provide insufficient information to determine long-term sickness absence risk profiles. There is a need for

    2012-04-01

    Full Text Available Background and Aim: High levels of job stress experienced over time, as well as personal frustration and inadequate coping skills, can lead to the syndrome known as burnout. In it has been shown in several surveys that high job stress in occupational therapists could lead to the burnout syndrome. Since few studies have been conducted in Iran concerning burnout in occupational therapists, we felt the necessity of performing this study to make Iranian therapists more aware of the syndrome and its related factors.Materials and Method: A cross sectional survey was carried out on 87 Iranian occupational therapists in the current study. A questionnaire consisting of two parts (demographic dates & maslach burnout inventory was sent to all therapists who were members of medical organization.Results: 80.4% of therapists reported mild to moderate symptoms of burnout, while nobody has reported severe burn out. Low job satisfaction (P value=0.038 and job experience less than 5 years (P value=0.049 were the two variables associated significantly with burnout.Conclusion: In the present study high rate prevalence of burnout shows that occupational therapists in Iran are not in a good health state and it can indicate that Iran health system should pay more attention to this group. According to our study the early years of a therapist’s carrier are the period when the therapist is at risk of burnout. So we believe that students should be given more information about burnout syndrome and its coping mechanisms during their education at the university.

    ABSTRACT The purpose of this study was to investigate perceptions of elementary school teachers on training in handwriting instruction received during their education, as well as their current classroom practices. The quantity and quality of training in handwriting instruction provided by baccalaureate degree-granting teacher education programs in North Carolina was also examined. An online survey was administered to each population identified to inquire about handwriting instruction practices. Results from 505 teachers and 16 professors indicated that while handwriting instruction content is valued by both teachers and professors, varied levels of training were provided to the teachers. Implications for occupational therapy practice are discussed including strategies for school-based therapists.

    2010-12-01

    Full Text Available This article reports on the validation of the Positive and Negative Occupational States Inventory (PNOSI, a new tool for measuring positive and negative occupational states. Three goals were defined: testing the structural validity of the PNOSI, testing its stability, and testing its convergent and discriminant validity with engagement, burnout, commitment, and workaholism. Data were collected in seven different companies (more than 16,000 participants. The factorial validity of the PNOSI was demonstrated using covariance structure analyses. A two-factor model with a negative occupational state factor and a positive occupational state factor fitted the data better than an alternative one-factor model. The two corresponding scales demonstrated good internal consistency. The results confirmed that positive and negative occupational states are distinct constructs and should be measured with different items. Convergent and discriminant validity with related constructs, namely engagement, burnout, commitment, and workaholism, were also demonstrated. The conclusion is that the PNOSI has good psychometric properties.

    2014-01-01

    Residential construction is a high-risk industry in the U.S. due to the exposure to work-related safety hazards and fall injuries. This study aimed to examine the safety training and safe work practices of construction workers within the small residential construction industry. In order to achieve the study objectives, a survey was designed and sent to approximately 200 Wisconsin based residential construction contractors. About one third of the respondents stated that they did not have any form of safety programs. The study indicated that the most common types of work-related injuries in residential construction were slips/trips/falls and cuts/lacerations. The survey findings also suggested that the residential construction contractors needed to increase the utilization of fall protection safety equipment. Further education and subject matter expert training could provide benefits to improve occupational safety and health of the small business workforce in the residential construction industry.

  17. Factors affecting occupational exposure to needlestick and sharps injuries among dentists in Taiwan: a nationwide survey.

    Hsin-Chung Cheng

    Full Text Available BACKGROUND: Although the risks of needlestick and sharps injuries (NSIs for dentists are well recognized, most papers published only described the frequency of occupational exposure to NSIs. Less has been reported assessing factors contributing to exposure to NSIs. The purpose of this study was to update the epidemiology of NSIs among dentists in Taiwan and identify factors affecting NSIs in order to find preventive strategies. METHODOLOGY/PRINCIPAL FINDINGS: A nationwide survey was conducted in dentists at 60 hospitals and 340 clinics in Taiwan. The survey included questions about factors supposedly affecting exposure to NSIs, such as dentist and facility characteristics, knowledge and attitudes about infectious diseases, and practices related to infection control. Univariate and multivariate logistic regression analyses were conducted to determine the association between risk factors and exposure to NSIs. In total, 434 (74.8% of 580 dentists returned the survey questionnaires, and 100 (23.0% reported that they had experienced more than one NSI per week. Our data showed that the risk of occupational NSIs is similarly heightened by an older age (odds ratio [OR], 3.18; 95% confidence interval [CI], 1.62-6.25, more years in practice (OR, 2.57; 95% CI, 1.41-4.69, working in clinics (OR, 1.73; 95% CI, 1.08-2.77, exhibiting less compliance with infection-control procedures (OR, 1.82; 95% CI, 1.04-3.18, having insufficient knowledge of blood-borne pathogens (OR, 1.67; 95% CI, 1.04-2.67, and being more worried about being infected by blood-borne pathogens (OR, 1.82; 95% CI, 1.05-3.13. CONCLUSIONS/SIGNIFICANCE: High rates of NSIs and low compliance with infection-control procedures highly contribute to the chance of acquiring a blood-borne pathogen infection and threaten occupational safety. This study reveals the possible affecting factors and helps in designing prevention strategies for occupational exposure to NSIs.

    Full Text Available Abstract Background The frequent use of chiropractic, naturopathic, and physical and occupational therapy by patients with fibromyalgia has been emphasized repeatedly, but little is known about the attitudes of these therapists towards this challenging condition. Methods We administered a cross-sectional survey to 385 senior Canadian chiropractic, naturopathic, physical and occupational therapy students in their final year of studies, that inquired about attitudes towards the diagnosis and management of fibromyalgia. Results 336 students completed the survey (response rate 87%. While they disagreed about the etiology (primarily psychological 28%, physiological 23%, psychological and physiological 15%, unsure 34%, the majority (58% reported that fibromyalgia was difficult to manage. Respondants were also conflicted in whether treatment should prioritize symptom relief (65% or functional gains (85%, with the majority (58% wanting to do both. The majority of respondents (57% agreed that there was effective treatment for fibromyalgia and that they possessed the required clinical skills to manage patients (55%. Chiropractic students were most skeptical in regards to fibromyalgia as a useful diagnostic entity, and most likely to endorse a psychological etiology. In our regression model, only training in naturopathic medicine (unstandardized regression coefficient = 0.33; 95% confidence interval = 0.11 to 0.56 and the belief that effective therapies existed (unstandardized regression coefficient = 0.42; 95% confidence interval = 0.30 to 0.54 were associated with greater confidence in managing patients with fibromyalgia. Conclusion The majority of senior Canadian chiropractic, naturopathic, physical and occupational therapy students, and in particular those with naturopathic training, believe that effective treatment for fibromyalgia exists and that they possess the clinical skillset to effectively manage this disorder. The majority place high priority

    2013-07-01

    In intelligent buildings, practical sensing systems designed to gather indoor occupancy information play an indispensable role in improving occupant comfort and energy efficiency. In this paper, we propose a novel method for occupancy measurement based on the video surveillance now widely used in buildings. In our method, we analyze occupant detection both at the entrance and inside the room. A two-stage static detector is presented based on both appearances and shapes to find the human heads in rooms, and motion-based technology is used for occupant detection at the entrance. To model the change of occupancy and combine the detection results from multiple vision sensors located at entrances and inside rooms for more accurate occupancy estimation, we propose a dynamic Bayesian network-based method. The detection results of each vision sensor play the role of evidence nodes of this network, and thus, we can estimate the true occupancy at time t using the evidence prior to (and including) time t. Experimental results demonstrate the effectiveness and efficiency of the proposed method.

    Poor mental health has become a serious social and public health-care burden. This cross-sectional study used multistage stratified cluster random sampling to gather mental health information from 11,891 adults (18–60 years) employed in various occupations categorized according to the Chinese Standard Occupational Classification. Mental health was measured by the General Health Questionnaire, and participants exceeding the cut-off score were defined as having poor mental health. The overall prevalence of poor mental health was 23.8%. The prevalence of poor mental health was significantly higher in the Han ethnic group than Kazak ethnic group and in health-care workers, teachers, and civil servants compared to manual workers. Females (odds ratios (OR) = 1.139, 95% confidence intervals (CI): 1.012–3.198) and knowledge workers (1.697, 1.097–2.962) were risk factors for poor mental health, while Kazak ethnicity (0.465, 0.466–0.937), other minority status (non-Han) (0.806, 0.205–0.987), and working ≥15 years in the same occupation (0.832, 0.532–0.932) were protective (p mental health in Xinjiang, China, is higher in the Kazak ethnic group than the Han ethnic group. The prevalence of poor mental health is higher among knowledge workers than in manual workers due to high incidences of poor mental health in civil servants, health-care workers, and teachers.

  5. Statistical Analysis and Modeling of Occupancy Patterns in Open-Plan Offices using Measured Lighting-Switch Data

    Energy Technology Data Exchange (ETDEWEB)

    Chang, Wen-Kuei; Hong, Tianzhen

    2013-01-01

    Occupancy profile is one of the driving factors behind discrepancies between the measured and simulated energy consumption of buildings. The frequencies of occupants leaving their offices and the corresponding durations of absences have significant impact on energy use and the operational controls of buildings. This study used statistical methods to analyze the occupancy status, based on measured lighting-switch data in five-minute intervals, for a total of 200 open-plan (cubicle) offices. Five typical occupancy patterns were identified based on the average daily 24-hour profiles of the presence of occupants in their cubicles. These statistical patterns were represented by a one-square curve, a one-valley curve, a two-valley curve, a variable curve, and a flat curve. The key parameters that define the occupancy model are the average occupancy profile together with probability distributions of absence duration, and the number of times an occupant is absent from the cubicle. The statistical results also reveal that the number of absence occurrences decreases as total daily presence hours decrease, and the duration of absence from the cubicle decreases as the frequency of absence increases. The developed occupancy model captures the stochastic nature of occupants moving in and out of cubicles, and can be used to generate a more realistic occupancy schedule. This is crucial for improving the evaluation of the energy saving potential of occupancy based technologies and controls using building simulations. Finally, to demonstrate the use of the occupancy model, weekday occupant schedules were generated and discussed.

  6. A Direct Measurement of the Mean Occupation Function of Quasars: Breaking Degeneracies between Halo Occupation Distribution Models

    CERN Document Server

    Chatterjee, Suchetana; Myers, Adam; Zheng, Zheng

    2013-01-01

    Recent work on quasar clustering suggests a degeneracy in the halo occupation distribution constrained from two-point correlation functions. To break this degeneracy, we make the first empirical measurement of the mean occupation function (MOF) of quasars at z ~ 0.2 by matching quasar positions with groups and clusters identified in the MaxBCG sample. We fit two models to the MOF, a power law and a 4-parameter model. The number distribution of quasars in host halos is close to Poisson, and the slopes of the MOF obtained from our best-fit models (for the power law case) favor a MOF that monotonically increases with halo mass. The best-fit slopes are 0.53 +/- 0.04 and 1.03 +/- 1.12 for the power law model and the 4-parameter model, respectively. We measure the radial distribution of quasars within dark matter halos and find it to be adequately described by a power law with a slope -2.3 +/- 0.4. We measure the conditional luminosity function (CLF) of quasars and show that there is no evidence of luminosity evolu...

    Full Text Available Measuring the energy efficiency of buildings and its confrontation with the current Building Energy Simulations now faces knowledge of what is commonly called “occupancy”. This work has been made in order to implement a monitoring system on a research demonstrator building at DLRCA in Angers (France. The goals were first to know the occupancy as input data of models but also to build occupancy models. Occupancy can be defined as all the action of occupants that affect building energy efficiency. The chosen monitoring deals with its presence, lightning, windows opening and internal gains. It seems that the use of an Infra- red detector allows a accuracy of 5 min in the detection of presence. The use of dry contact sensors allows the detection of five different rates of slide windows opening that can affect temperature decrease. Light sensors seem to be efficient to detect artificial lighting states when correctly configured.

    Full Text Available In this paper we describe a methodology for occupancy measure on beaches based on digital image processing techniques. This metric constitute a measure of interest for quantification of factors relates to the quality of user experience and is an import indicator in integrated management field. The proposed method has two main components: the preprocessing and occupancy density estimation. In the preprocessing stage a color correction approach is applied in order to minimize the illumination variance effects over the objects in the scene. Subsequently, the estimation begins delimiting the information regarding the environment using a mask or reference image. Gray-level gradient analysis is applied to the resulted image after the mask appliance. The results show a 2.6% margin of error that suggests the measure is an occupancy measure indicative. The obtained error is related to the auto occlusion identification and processing.

  11. Measuring and Detecting Errors in Occupational Coding: an Analysis of SHARE Data

    Directory of Open Access Journals (Sweden)

    Belloni Michele

    2016-12-01

    Full Text Available This article studies coding errors in occupational data, as the quality of this data is important but often neglected. In particular, we recoded open-ended questions on occupation for last and current job in the Dutch sample of the “Survey of Health, Ageing and Retirement in Europe” (SHARE using a high-quality software program for ex-post coding (CASCOT software. Taking CASCOT coding as our benchmark, our results suggest that the incidence of coding errors in SHARE is high, even when the comparison is made at the level of one-digit occupational codes (28% for last job and 30% for current job. This finding highlights the complexity of occupational coding and suggests that processing errors due to miscoding should be taken into account when undertaking statistical analyses or writing econometric models. Our analysis suggests strategies to alleviate such coding errors, and we propose a set of equations that can predict error. These equations may complement coding software and improve the quality of occupational coding.

    The purpose of this study was to evaluate, through a systematic review, assessment instruments for evidence-based practice (EBP). The specific objectives were to (1) identify survey instruments testing EBP knowledge, skills, attitudes and behaviour; (2) determine the attributes measured by each instrument; (3) evaluate the psychometric properties of the instruments; and (4) evaluate the methodological quality of the instruments. Using the Cochrane approach, searches were conducted in Pubmed, EBSCOHost and Scopus from inception to February 2014. Papers were screened by two independent assessors, and data were extracted by one researcher. Forty papers reporting 34 instruments met the inclusion criteria and were included in the qualitative synthesis. Most instruments measured EBP behaviour (n = 33) and attitudes (n = 21). This review provides a single source of information to enable researchers to select the most robust descriptive instruments to measure EBP learner attributes. Instruments used only with occupational therapists may have resulted in some instruments being missed. For further research, it is recommended that attention is given to developing objective instruments with a focus on knowledge and skills. Copyright © 2015 John Wiley & Sons, Ltd.

    Full Text Available BACKGROUND: A cross-sectional survey on knowledge and perception of occupational biological risk among workers in several occupations was carried out in the industrial area of Rome. METHODS: The study was carried out in the period of March-April 2010 using a questionnaire with 33 items on the following areas: a socio-demographic data; b perception of the biological risks in ordinary occupational activity; c knowledge about biological risks; d biological risks in the working environment. The questionnaire was submitted to a convenience sample of workers of an industrial area in Southern Rome. RESULTS: 729 participants entered the study from the following work activities: food, catering, service, farming and breeding, healthcare, school and research (males 57.2%; mean age 37.4 years, SD = 10.9. Significant associations were found between different activity areas with respect to the relevance of the biological risk (p = 0.044 and the perception of the biological risk (p < 0.001. With respect to vehicles of infectious agents, the highest percentages of the most common biological risk exposures were: air and physical contact for the catering and food group, 66.7% and 61.90% respectively; air and blood for the health and research group, with 73.50% and 57.00% respectively; and physical contact and blood for the service group, 63.10 % and 48.30%. Significant difference of proportions were found about the prevalent effect caused by the biological agents was the occurrence of infectious diseases (59.90% food group, 91.60% health and research and 79.30% service group (p < 0.001. The perception of knowledge resulted in a good rank (sufficient, many or complete in the food and catering group, 78.3% with significant difference compared to other professions (p < 0.001. CONCLUSIONS: All participants show good knowledge the effects induced by biological agents and it is significant that almost half of the respondents are aware of the risks concerning allergies

    2009-10-01

    The aim of this pilot project was to investigate the occurrence of occupational exposure to blood and body fluids in registered physiotherapists in Western Australia. Surveys were sent to physiotherapists with questions regarding personal background, exposure characteristics, and contributing factors included. Descriptive statistical methods were used to identify the area of practice posing the highest risk of exposure to physiotherapists. The authors found that 56.1% of surveyed physiotherapists recorded one or more exposures within the past 5 years. Work in hospitals was found to carry the highest rate of exposure for the physiotherapy profession. Other areas of practice, including community work, private practice, nursing homes/hostels, and work at sporting events carry comparable but lower risks of exposure. In private practice, 50% of exposures were associated with acupuncture. In nursing homes, 60% of exposures were brought on by exposure to contaminated materials, whereas in the community setting most exposures (64%) were attributed to unpredictable/uncontrollable situations. At sporting events, 90% of all exposures were associated with already existing sources of blood and body fluids (wounds). Within the hospital setting, the 3 dominant immediate causes reported were unpredictable situations (33.3%), existing sources (28.4%), and procedural causes (22.2%). The use of personal protective equipment for prevention of exposure is investigated and discussed. Data collected for this survey were not enough to draw conclusive assumptions regarding hazard management. A repeat of this study on a larger scale may provide physiotherapists with the tools and knowledge to minimize the likelihood of exposure and harm arising from exposure.

    Full Text Available Abstract Background Health staff in Afghanistan may be at high risk of needle stick injury and occupational infection with blood borne pathogens, but we have not found any published or unpublished data. Methods Our aim was to measure the percentage of healthcare staff reporting sharps injuries in the preceding 12 months, and to explore what they knew about universal precautions. In five randomly selected government hospitals in Kabul a total of 950 staff participated in the study. Data were analyzed with Epi Info 3. Results Seventy three percent of staff (72.6%, 491/676 reported sharps injury in the preceding 12 months, with remarkably similar levels between hospitals and staff cadres in the 676 (71.1% people responding. Most at risk were gynaecologist/obstetricians (96.1% followed by surgeons (91.1%, nurses (80.2%, dentists (75.4%, midwives (62.0%, technicians (50.0%, and internist/paediatricians (47.5%. Of the injuries reported, the commonest were from hollow-bore needles (46.3%, n = 361/780, usually during recapping. Almost a quarter (27.9% of respondents had not been vaccinated against hepatitis B. Basic knowledge about universal precautions were found insufficient across all hospitals and cadres. Conclusion Occupational health policies for universal precautions need to be implemented in Afghani hospitals. Staff vaccination against hepatitis B is recommended.

    To investigate the occupational hazards among Chinese female workers in the electronics industry, the authors systematically sampled a total of 8,300 female workers at random across 4 provinces in a variety of electronics factories. A detailed questionnaire was used to collect information on occupational hazards and the occurrence of occupation-related diseases. The results show that 4,283 female workers (51.9%) were exposed to 1 or more occupational hazards. The most common chemical hazard was organic solvent, and the second most common was heavy metals. The ergonomic hazards included repetitive movements, poor standing posture, and the lifting of heavy goods. More than 60% of the female workers self-reported occupation-related diseases. These results showed that occupational health hazards were common in the electronics industry in China and that they caused serious occupation-related health problems for the female workers therein.

    2011-06-01

    Full Text Available The Sado River Drainage Survey project (2004-2008 was designed to fill a significant gap in our knowledge of the prehistory of Portugal. Southern Alentejo constitutes nearly one third of the total land mass of continental Portugal, but has received comparatively little attention from Palaeolithic archaeologists. Practically nothing was known about the prehistory of the Sado River basin, which includes the southern Alentejo plain, before now. The results of the Sado River Drainage Survey (SRDS indicate that the Sado River basin was likely occupied at low population densities during the Middle Palaeolithic. There is some evidence for a Lower Palaeolithic presence but little or no evidence of an Upper Palaeolithic occupation. The emerging pattern suggests either an occupational hiatus or a major shift in settlement pattern towards the end of the Middle Palaeolithic. Possible explanations for this pattern, including aridification driven by climate change, are explored here.

    El proyecto de prospección de la cuenca del río Sado (SRDS, llevado a cabo entre el 2004 y el 2008, se diseñó para suplir la carencia de información concerniente al conocimiento actual de la Prehistoria de Portugal. Aunque la cuenca del río Sado conforma casi un tercio de la superficie continental de Portugal, aún no había recibido la debida atención para el Paleolítico. Antes de este proyecto, prácticamente nada se conocía acerca de la Prehistoria de dicha cuenca, incluyendo la llanura de Alentejo. Nuestros resultados indican una baja densidad de población durante el Paleolítico Medio, rastro de ocupaciones del Paleolítico Inferior y casi ninguna evidencia de ocupaciones asociadas al Paleolítico Reciente. A partir de los datos obtenidos, se desprende un modelo en el que se evidencia que, hacia finales del Paleolítico Medio, hubo una discontinuidad en la ocupación, probablemente asociada a cambios climáticos o del uso del territorio.

    Background Studies suggest employers underreport injuries to the Bureau of Labor Statistics Survey of Occupational Injuries and Illnesses (SOII); less is known about reporting differences by establishment characteristics. Methods We linked SOII data to Washington State workers’ compensation claims data, using unemployment insurance data to improve linking accuracy. We used multivariable regression models to estimate incidence ratios (IR) of unreported workers’ compensation claims for establishment characteristics. Results An estimated 70% of workers’ compensation claims were reported in SOII. Claims among state and local government establishments were most likely to be reported. Compared to large manufacturing establishments, unreported claims were most common among small educational services establishments (IR = 2.47, 95%CI: 1.52–4.01) and large construction establishments (IR = 2.05, 95%CI: 1.77–2.37). Conclusions Underreporting of workers’ compensation claims to SOII varies by establishment characteristics, obscuring true differences in work injury incidence. Findings may differ from previous research due to differences in study methods. Am. J. Ind. Med. 59:274–289, 2016. © 2016 The Authors.

    Evidence demonstrates that health care professionals are more prone to burnout than other professionals due to the emotionally taxing interactions they have with their patients on a daily basis. The aims of this study were to measure occupational burnout levels among sonographers, radiographers and radiologists and to examine predictors of burnout according to demographic characteristics. A cross-sectional online survey was administered in 2010 to radiographers, sonographers and radiologists who were members of the following professional bodies: Australian Institute of Radiography, Australian Sonographers Association and The Royal Australian and New Zealand College of Radiologists. The Maslach Burnout Inventory was used to measure burnout levels for each profession. Data were analysed using SPSS Ver 20 (IBM, Chicago, IL, USA) statistical software. A total of 613 radiographers, 121 sonographers and 35 radiologists participated in the survey. Radiographers, sonographers and radiologists had a high mean (±SD) burnout score for emotional exhaustion (39.9 ± 8.5, 42.2 ± 8.5 and 44.9 ± 7.1 respectively) and depersonalization (18.9 ± 5.5, 20.3 ± 5.8 and 20.6 ± 5.6) compared to MBI norms. Radiographers also had low personal achievement (30.8 ± 5.5) compared to MBI norms. Radiographers and sonographers who were male, worked >10 hours overtime and spent Burnout levels among radiographers, sonographers and radiologists are high and likely to vary according to some demographic and work-related factors. Further research is needed to examine ways to alleviate burnout in these professions so that loss of experienced staff due to burnout can be minimized and quality of patient care can be maintained. © 2016 The Royal Australian and New Zealand College of Radiologists.

    Full Text Available Unintentional injuries cause much of the global mortality burden, with the workplace being a common accident setting. Even in high-income economies, occupational injury figures remain remarkably high. Because risk factors for occupational injuries are prone to confounding, the present research takes a comprehensive approach. To better understand the occurrence of occupational injuries, sociodemographic factors and work- and health-related factors are tested simultaneously. Thus, the present analysis aims to develop a comprehensive epidemiological model that facilitates the explanation of varying injury rates in the workplace. The representative phone survey German Health Update 2010 provides information on medically treated occupational injuries sustained in the year prior to the interview. Data were collected on sociodemographics, occupation, working conditions, health-related behaviors, and chronic diseases. For the economically active population (18-70 years, n = 14,041, the 12-month prevalence of occupational injuries was calculated with a 95% confidence interval (CI. Blockwise multiple logistic regression was applied to successively include different groups of variables.

    We examine the validity of the emergency department (ED) occupancy rate as a measure of crowding by comparing it to the Emergency Department Work Index Score (EDWIN), a previously validated scale. A multicenter validation study was conducted according to ED visit data from 6 academic EDs for a 3-month period in 2005. Hourly ED occupancy rate (ie, total number of patients in ED divided by total number of licensed beds) and EDWIN scores were calculated. The correlation between the scales was determined and their validity evaluated by their ability to discriminate between hours when 1 or more patients left without being seen and hours when the ED was on ambulance diversion, using area under the curve (AUC) statistics estimated from the bootstrap method. We calculated the ED occupancy rate and EDWIN for 2,208 consecutive hours at each of the 6 EDs. The overall correlation between the 2 scales was 0.58 (95% confidence interval [CI] 0.56 to 0.60). The ED occupancy rate (AUC=0.73; 95% CI 0.65 to 0.80) and the EDWIN (AUC=0.65; 95% CI 0.58 to 0.72) did not differ significantly in correctly identifying hours when patients left without being seen. The ED occupancy rate (AUC=0.78; 95% CI 0.75 to 0.80) and the EDWIN (AUC=0.70; 95% CI 0.59 to 0.81) performed similarly for ED diversion hours. The ED occupancy rate and the EDWIN classified leaving without being seen and ambulance diversion hours with moderate accuracy. Although the ED occupancy rate is not ideal, its simplicity makes real-time assessment of crowding feasible for more EDs nationwide.

    Earlier studies conducted at 400 and 110 kV substations in Finland have shown that the occupational exposure to electric fields can exceed the action levels (ALs) set by Directive 2013/35/EU. This is a case study investigating the level of occupational exposure experienced by workers at 220 kV substations in order to determine if the actions levels are being exceeded. The measurements were conducted at two old 220 kV substations in Finland. The higher AL of 20 kV m-1 was exceeded at both substations.

    Nanoparticles are used in many applications because of their novel properties compared to bulk material. A growing number of employees are working with nanomaterials and their exposure to nanoparticles trough inhalation must be evaluated and monitored continuously. However, there is an ongoing debate in the scientific literature about what are the relevant parameters to measure to evaluate exposure to level. In this study, three types of nanoparticles (ammonium sulphate, synthesised TiO{sub 2} agglomerates and aerosolised TiO{sub 2} powder, modes in a range of 30-140 nm mobility size) were measured with commonly used aerosol measurement instruments: scanning and fast mobility particle sizers (SMPS, FMPS), electrical low pressure impactor (ELPI), condensation particle counter (CPC) together with nanoparticle surface area monitor (NSAM) to achieve information about the interrelations of the outputs of the instruments. In addition, the ease of use of these instruments was evaluated. Differences between the results of different instruments can mainly be attributed to the nature of test particles. For spherical ammonium sulphate nanoparticles, the data from the instruments were in good agreement while larger differences were observed for particles with more complex morphology, the TiO{sub 2} agglomerates and powder. For instance, the FMPS showed a smaller particle size, a higher number concentration and a narrower size distribution compared with the SMPS for TiO{sub 2} particles. Thus, the type of the nanoparticle was observed to influence the data obtained from these different instruments. Therefore, care and expertise are essential when interpreting results from aerosol measurement instruments to estimate nanoparticle concentrations and properties.

    Understanding occupational variations in health risks is necessary to identify high risk groups. We examined the recent prevalence of obesity, heavy alcohol consumption, smoking, and leisure time physical activity (PA) across occupations. Data from the 2010 National Health Interview Survey were used. Analysis was limited to adults, 18 and older who had a job or business the week before the interview (n = 14,754). Adjusted prevalences of outcomes across occupations were calculated using logistic regression. The highest prevalence of obesity was within community and social services and morbid obesity was in computer and mathematical occupations. That of smoking was highest in healthcare support, heavy drinking in food preparation and serving related, and non-adherence to PA recommendations in the farming, fishing, and forestry occupations. Important health risk factors vary across occupations. Worksite and public health interventions need to be designed and modified to address such occupational health disparities. © 2014 Wiley Periodicals, Inc.

  16. A survey report: how hospitals measure liquidity.

    Science.gov (United States)

    Cleverley, W O; Massar, G S

    1983-11-01

    Liquidity is an important financial concept that is widely understood although not authoritatively defined. In many situations the actual assessment of liquidity is based on the relationship of current assets and current liabilities. Nationally, a decline in traditional measures of liquidity such as current and quick ratios has occurred for both general industry and the hospital industry. There are a variety of possible explanations for this trend, but one of special interest in this article was the effect of financial reporting practices. A recent Principles & Practices Board survey of Financial Analysis Service subscribers indicated that there is a potential for underreporting working capital, (current assets less current liabilities), in the hospital industry. However, this does not necessarily imply that the recent decline in liquidity measures is in any way due to reporting practices. No information about changes in reporting practices was obtained in this study. Finally, the results of the study do suggest that examination of more than one liquidity indicator is useful. Specifically, restricting attention to just the current ratio could be misleading. In this vein, it is interesting to note that six measures of liquidity are used in the FAS. All may provide insight into an accurate assessment of liquidity.

Objective: To assess the awareness of occupational hazards and utilization of safety measures among welders in coastal South India. Methods: A cross-sectional study was conducted among 209 welders in Puducherry, South India. Baseline characteristics, awareness of health hazards, safety measures and their availability to and utilization by the participants were assessed using a pre-tested structured questionnaire. Results: The majority of studied welders aged between 20 and 40 years (n=160, 76.6% and had 1-10 years of education (n=181, 86.6%. They were more aware of hazards (n=174, 83.3% than safety measures (n=134, 64.1%. The majority of studied welders utilized at least one protective measure in the preceding week (n=200, 95.7%. Many of them had more than 5 years of experience (n=175, 83.7%, however, only 20% of them had institutional training (n=40, 19.1%. Age group, education level, and utilization of safety measures were significantly associated with awareness of hazards in univariate analysis (p<0.05. Conclusion: Awareness of occupational hazards and utilization of safety measures is low among welders in coastal South India, which highlights the importance of strengthening safety regulatory services towards this group of workers.

    Additional findings are presented from a 2012 nationwide survey of 2,072 occupational health nurses regarding how they achieved competence in respiratory protection, their preferred methods of learning, and how they motivated employees to use respiratory protection. On-the-job training, taking a National Institute for Occupational Safety and Health spirometry course, or attending professional conferences were the primary ways occupational health nurses gained respiratory protection knowledge. Attending professional conferences was the preferred method of learning, varying by type of industry and years of occupational health nurse experience. Employee motivational strategies were not widely used; the most common strategy was to tailor respiratory protection training to workplace culture. Designing training methods that match learning preferences, within the context of the organization's safety and quality improvement culture, is a key recommendation supported by the literature and these findings. Including respiratory protection content and competencies in all levels of academic nursing education is an additional recommendation. Additional research is needed to link training strategies with consistent and correct use of respiratory protection by employees.

    The purpose of this study was to investigate the prevalence of occupational exposure incidents among undergraduate dental students and the factors associated with it in the educational dental clinics at Pharos University in Alexandria - Egypt, and to measure the commitment with applying infection control policy in the form of compliance with post-exposure management protocol and reporting exposure incidents. An anonymous self-administered questionnaire consisting of thirteen multiple-choice questions was distributed among 350 undergraduate dental students in mid-senior and senior levels during lectures at the end of the second semester of 2011, with a response rate of 90.00%. About 62.00% of the senior students reported that exposures occurred outside the patient's mouth. A high percentage of both the mid-senior and senior students (74.70% and 70.70%, respectively) reported that they were exposed to multiple sources of incidents. The vast majority of studied groups stated that they didn't follow Infection Control Protocol after Incident Exposure. The findings of this study confirm that dental students experience exposure incidents but are not likely to report them, thus it is important that the principles of infection control training and reporting of all exposure incidents continue to be emphasized throughout undergraduate dental education.

  1. Ignoring imperfect detection in biological surveys is dangerous: a response to 'fitting and interpreting occupancy models'.

    Directory of Open Access Journals (Sweden)

    Gurutzeta Guillera-Arroita

    Full Text Available In a recent paper, Welsh, Lindenmayer and Donnelly (WLD question the usefulness of models that estimate species occupancy while accounting for detectability. WLD claim that these models are difficult to fit and argue that disregarding detectability can be better than trying to adjust for it. We think that this conclusion and subsequent recommendations are not well founded and may negatively impact the quality of statistical inference in ecology and related management decisions. Here we respond to WLD's claims, evaluating in detail their arguments, using simulations and/or theory to support our points. In particular, WLD argue that both disregarding and accounting for imperfect detection lead to the same estimator performance regardless of sample size when detectability is a function of abundance. We show that this, the key result of their paper, only holds for cases of extreme heterogeneity like the single scenario they considered. Our results illustrate the dangers of disregarding imperfect detection. When ignored, occupancy and detection are confounded: the same naïve occupancy estimates can be obtained for very different true levels of occupancy so the size of the bias is unknowable. Hierarchical occupancy models separate occupancy and detection, and imprecise estimates simply indicate that more data are required for robust inference about the system in question. As for any statistical method, when underlying assumptions of simple hierarchical models are violated, their reliability is reduced. Resorting in those instances where hierarchical occupancy models do no perform well to the naïve occupancy estimator does not provide a satisfactory solution. The aim should instead be to achieve better estimation, by minimizing the effect of these issues during design, data collection and analysis, ensuring that the right amount of data is collected and model assumptions are met, considering model extensions where appropriate.

    Since 2002, the Centers for Medicare and Medicaid Services have reported quality measures on the Nursing Home Compare Web site. It has been assumed that nursing homes are able to make improvements on these measures. In this study researchers examined nursing homes to see whether they have improved their quality scores, after accounting for regression to the mean. Researchers also examined whether gains varied according to market competition or market occupancy rates. They identified some regression to the mean for the quality measure scores over time; nevertheless, they also determined that some nursing homes had indeed made small improvements in their quality measure scores. As would be predicted based on the market-driven mechanism underlying quality improvements using report cards, the greatest improvements occurred in the most competitive markets and in those with the Lowest average occupancy rates. As policies to promote more competition in Long-term care proceed, further reducing occupancy rates, further, albeit small, quality gains will likely be made in the future.

    Full Text Available Occupational health nurses (OHNs are qualified registered nurses with a postgraduate qualification in occupational health nursing. An important activity of OHNs is to identify and assess health risks in the workplace. Health risk assessments (HRAs are conducted by OHNs to determine all the occupational health stressors, for example noise, vibration and chemical substances. The authors conducted legal compliance occupational health audits and observed that 85% (n = 23 of OHNs in different settings conduct HRAs only to a limited extent. The following objective was formulated for the study: To explore and describe the extent to which OHNs conduct HRAs as it is a legal requirement for compliance; and the possible reasons for not adhering to the regulation and conduct them only to a limited extent. A quantitative, descriptive design was used in this study. A sampling frame was developed from a list of all the members of the South African Society of Occupational Health Nursing Practitioners (SASOHN in Gauteng. From the target population of OHNs in Gauteng, a systematic cluster sampling method was used. A self-developed questionnaire was distributed by mail and e-mail, and authors sent respondents reminders. The authors ensured that validity, reliability and ethical standards were adhered to. The findings revealed that OHNs are mature, experienced, predominately female practitioners who operate on behalf of a disproportionately large number of workers. Four factors influencing these nurses in conducting an HRA to a limited extent were identified: competence, ignorance about the role of the OHN, workload and attitude.

    Occupational skin disease is a common problem among health care workers (HCWs). The prevalence of occupational skin disease in HCWs has been reported in several international studies, but not in the UK. To estimate the prevalence of occupational skin disease in a population of UK HCWs and to explore possible causative factors. Clinical and non-clinical HCWs attending for an influenza vaccine during October and November 2013 were invited to complete a brief skin questionnaire. Data from staff who stated their skin had suffered as a result of work were compared with data from staff who did not, to explore differences in potential causative factors. A total of 2762 questionnaires were analysed. The estimated prevalence of occupational skin disease was 20% for clinical and 7% for non-clinical staff. In total, 424 clinical staff stated their skin had been made worse by work. There were statistically significant differences between clinical staff with and without reported skin symptoms regarding a history of eczema, frequent hand washing and moisturizer use but no statistically significant difference in the relative proportions of soap and alcohol hand gel use. Non-clinical staff reported significantly more use of soap relative to alcohol gel than clinical staff. This study demonstrated the prevalence of occupational skin disease in a population of UK HCWs. More work is indicated to explore if the ratio of soap and alcohol gel reported in this study are typical and whether this has any impact on the development of occupational skin disease. © The Author 2014.

    Full Text Available Galaxy redshift surveys have achieved significant progress over the last couple of decades. Those surveys tell us in the most straightforward way what our local Universe looks like. While the galaxy distribution traces the bright side of the Universe, detailed quantitative analyses of the data have even revealed the dark side of the Universe dominated by non-baryonic dark matter as well as more mysterious dark energy (or Einstein's cosmological constant. We describe several methodologies of using galaxy redshift surveys as cosmological probes, and then summarize the recent results from the existing surveys. Finally we present our views on the future of redshift surveys in the era of precision cosmology.

    Full Text Available Background: Team-Based Learning (TBL is an active instructional approach used in health care education that incorporates group work. Methods: Two occupational therapy professors adopted a TBL instructional approach in two courses for firstand second-year occupational therapy master’s degree level students. The investigators administered a survey to evaluate student perceptions of TBL and lecture-based instruction (LBI. A principal components factor analysis with varimax rotation identified two 5-item factors: “perceptions of LBI” and “perceptions of TBL.” Internal consistency for each factor was strong (Cronbach’s alpha 5 0.856 [preference for LBI]; 0.865 [preference of TBL]. A Wilcoxon matched pairs signed rank test was conducted to determine whether there was a difference in the ranking of two teaching approaches. Results: The results indicated a significant difference in how the students ranked the instructional approaches, z = -3.19, p < .05, with the students having more positive perceptions of LBI than TBL. Conclusion: The implications for occupational therapy educators are discussed.

    The objective of the present study is to compare distal femoral cartilage thicknesses of patients with occupational lead exposure with those of healthy subjects by using ultrasonography. A total of 48 male workers (a mean age of 34.8±6.8 years and mean body mass index (BMI) of 25.8±3.1 kg/m(2)) with a likely history of occupational lead exposure and age- and BMI-matched healthy male subjects were enrolled. Demographic and clinical characteristics of the patients, that is, age, weight, height, occupation, estimated duration of lead exposure, and smoking habits were recorded. Femoral cartilage thickness was assessed from the midpoints of right medial condyle (RMC), right lateral condyle (RLC), right intercondylar area (RIA), left medial condyle (LMC), left lateral condyle (LLC), and left intercondylar area (LIA) by using ultrasonography. Although the workers had higher femoral cartilage thickness values at all measurement sites when compared with those of the control subjects, the difference reached statistical significance at RLC (P=0.010), LMC (P=0.001), and LIA (P=0.039). There were no correlations between clinical parameters and cartilage-thickness values of the workers. Subjects with a history of lead exposure had higher femoral cartilage thickness as compared with the healthy subjects. Further studies, including histological evaluations, are awaited to clarify the clinical relevance of this increase in cartilage thickness and to explore the long-term follow-up especially with respect to osteoarthritis development.

    2016-06-01

    The threshold limit value (TLV) guideline for ultraviolet (UV) radiation specifies that irradiance measurements to ensure occupant safety be taken over an angle of 80° at the sensor. The purpose of this study was to evaluate the effect of an 80° field of view (FOV) tube on lower room UV-C irradiation measurements. Measurements were made in an experimental chamber at a height of 1.73m with and without an FOV tube. The FOV tube reduced the lower room irradiance readings by 18-34%, a statistically significant reduction compared to the bare sensor. An 80° FOV tube should be used for lower room irradiance measurements to comply with the TLV guideline. The resulting lower readings would allow more UV-C radiation in the upper room without compromising occupant safety. More UV-C radiation in the upper room could increase efficacy of UVGI systems for reducing transmission of airborne infectious diseases. In addition, recommendations are made to standardize lower room irradiance measurement techniques.

    2008-01-01

    The automotive repair and refinishing industry has been studied intensively in industrialized countries, in part due to use of hazardous chemicals such as isocyanates and solvents, but little is known about industry practices in the developing world. The main objective of this paper was to investigate environmental and occupational work practices of this industry in a developing region, Sonora, Mexico. An integrated survey approach maximizes the opportunity for identifying risks as well as reducing risks. This investigation included detailed workplace visits to 41 body shops and 6 paint suppliers, as well as a survey of shop owners and 24 workers. Information was collected on work practices, level of technology in the shops, use of personal protective equipment, consumption and handling of hazardous chemicals and waste, hazard communication, and environmental consciousness. Most shops had little capital, outdated technology for exposure control, poor working conditions, high potential for exposure to hazardous chemicals, and little awareness of environmental and occupational health and safety. We concluded that work practices in the Sonoran auto refinishing industry are unsustainable and may pose a health risk to workers and the environment.

    Frequency tables were prepared and coefficient of correlation was computed to check correlation between different variables. Statistical significance was set at P < 0.05. Results: The most common occupational hazard reported was injury from "sharps" (77%, out of which needle prick injury was the most frequent. Of the other occupational problems job related stress (43.3%, musculoskeletal problems (39.8%, and allergies (23.8% from things used in dental clinics were most common. A reasonably high percentage of dentists were immunized against hepatitis-B virus (88.4% and were following proper infection control measures and hospital waste disposal methods. Very few dentists were following the correct method of disposal of excess amalgam (11% and measurement of radiation exposure (27.5% within their clinic. Most of them (90.2% were satisfied with their current working hours and job. Conclusion: Prevalence of occupational hazards among the studied group was high and certain preventive measures were not being followed properly. Therefore, there is a need to improve the knowledge of dentists regarding these hazards and their prevention.

    1996-04-01

    A survey was created to gauge how health and safety (H&S) resources are allocated in the biotechnology industry and to help understand the concerns of industry H&S professionals. A questionnaire was distributed to "the person most responsible for health and safety" at 34 companies; 12 commercial firms responded. Nearly 68% of the work force monitored did not fall into any biohazard classification. Almost 80% of work involving biohazards was considered "exempt" or "BL-1" under the Centers for Disease Control and Prevention classification system, indicating that most work was performed involving organisms of low pathogenic potential. H&S program development and administration is mature; 100% of respondents report having written programs for chemical, biological, and physical hazards. Chemical safety programs occupied, on average, the greatest percentage of the H&S professionals' time (46%), followed by biosafety (29.6%) and physical hazards (16.4%). The person most responsible for H&S averaged 65% of work time on H&S issues, while only 25% described their full-time responsibilities as H&S related. Staffing levels for companies with more than about 100 technical workers approximated 1.0-1.5 full-time H&S staff equivalents per 100 technical workers. This figure compares favorably with levels reported in a benchmarking survey of hospitals. Investigation into accident rates as a measure of H&S program effectiveness suggests that the biotechnology industry is a relatively safe one. Lost time injury and illness rates were significantly lower for the 12 participating companies than the accident frequency rates in the Standard Industrial Classification codes selected for comparison.

    To identify occupational stressors and coping resources in a group of physiotherapists, and to analyse interactions between subjective levels of stress, efficacy in stress resolution and coping resources used by these professionals. A sample of 55 physiotherapists working in three general hospitals in Portugal completed the Coping Resources Inventory for Stress, the Occupational Stressors Inventory and two subjective scales for stress and stress resolution. Most physiotherapists perceived that they were moderately stressed (19/55, 35%) or stressed (20/55, 36%) due to work, and reported that their efficacy in stress resolution was moderate (25/54, 46%) or efficient (23/54, 42%). Issues related to lack of professional autonomy, lack of organisation in the hierarchical command chain, lack of professional and social recognition, disorganisation in task distribution and interpersonal conflicts with superiors were identified as the main sources of stress. The most frequently used coping resources were social support, stress monitoring, physical health and structuring. Perceived efficacy in stress resolution was inversely related to perceived level of occupational stress (r=-0.61, P<0.01). Significant correlations were found between several coping resources and the perceived level of stress and efficacy in stress resolution. Associations between problem solving, cognitive restructuring and stress monitoring and both low levels of perceived stress and high levels of perceived efficacy were particularly strong. The importance of identifying stressors and coping resources related to physiotherapists' occupational stress, and the need for the development of specific training programmes to cope with stress are supported.

    Recent advances in magnetic resonance imaging (MRI) have increased occupational exposure to magnetic fields. In this study, we examined the assessment of occupational exposure to gradient magnetic fields and time-varying magnetic fields generated by motion in non-homogeneous static magnetic fields of MRI scanners. These magnetic field components can be measured simultaneously with an induction coil setup that detects the time rate of change of magnetic flux density (dB/dt). The setup developed was used to measure the field components around two MRI units (1 T open and 3 T conventional). The measured values can be compared with dB/dt reference levels derived from magnetic flux density reference levels given by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). The measured motion-induced dB/dt values were above the dB/dt reference levels for both MRI units. The measured values for the gradient fields (echo planar imaging (EPI) and fast field echo (FFE) sequences) also exceeded the dB/dt reference levels in positions where the medical staff may have access during interventional procedures. The highest motion-induced dB/dt values were 0.7 T s(-1) for the 1 T scanner and 3 T s(-1) for the 3 T scanner when only the static field was present. Even higher values (6.5 T s(-1)) were measured for simultaneous exposure to motion-induced and gradient fields in the vicinity of the 3 T scanner.

    Exposure to cadmium is recognized as a potentially serious health problem. A number of clinical abnormalities have been observed in workers occupationally exposed to cadmium. Therefore, it is essential that accurate data on body burdens be available in order to formulate dose-response relationships in man. The present Brookhaven facility for in vivo measurements of cadmium in man is described, and recent results from a field study to a cadmium production plant are reported. The cadmium content of the left kidney and concentration in the liver were measured by prompt-gamma neutron activation analysis in 82 occupationally exposed workers and 10 control subjects. Organ content ranged up to 57 mg in the kidney and up to 120 ppM in the liver for the industrial group. By contrast, the values for the control group ranged from 0.4 to 11.8 mg for the kidney and 0.7 to 7.9 ppM for the liver. The geometric means were 3.7 mg for the kidney and 2.7 ppM for the liver in the control group. When the data were analyzed to provide an estimate of the critical concentration for the kidney, a range of 300 to 400 ..mu..g/g for the renal cortex was calculated. These results are compared with the available data in the literature.

    This paper shows how Danish administrative register data can be combined with survey data at the person level and be used to validate information collected in the survey. Register data are collected by automatic third party reporting and the potential errors associated with the two data sources...... are therefore plausibly orthogonal. Two examples are given to illustrate the potential of combining survey and register data. In the first example expenditure survey records with information about total expenditure are merged with income tax records holding information about income and wealth. Income and wealth...... data are used to impute total expenditure which is then compared to the survey measure. Results suggest that the two measures match each other well on average. In the second example we compare responses to a one-shot recall question about total gross personal income ¿collected in another survey...

  8. Accounting for the Uncertainty Related to Building Occupants with Regards to Visual Comfort: A Literature Survey on Drivers and Models

    Full Text Available The interactions between building occupants and control systems have a high influence on energy consumption and on indoor environmental quality. In the perspective of a future of “nearly-zero” energy buildings, it is crucial to analyse the energy-related interactions deeply to predict realistic energy use during the design stage. Since the reaction to thermal, acoustic, or visual stimuli is not the same for every human being, monitoring the behaviour inside buildings is an essential step to assert differences in energy consumption related to different interactions. Reliable information concerning occupants’ behaviours in a building could contribute to a better evaluation of building energy performances and design robustness, as well as supporting the development of occupants’ education to energy awareness. The present literature survey enlarges our understanding of which environmental conditions influence occupants’ manual controlling of the system in offices and by consequence the energy consumption. The purpose of this study was to investigate the possible drivers for light-switching to model occupant behaviour in office buildings. The probability of switching lighting systems on or off was related to the occupancy and differentiated for arrival, intermediate, and departure periods. The switching probability has been reported to be higher during the entering or the leaving time in relation to contextual variables. In the analysis of switch-on actions, users were often clustered between those who take daylight level into account and switch on lights only if necessary and people who totally disregard the natural lighting. This underlines the importance of how individuality is at the base of the definition of the different types of users.

    Based on hospital discharges in 1001-2010, we calculated risk of tumours with an elevated occupational and environmental etiological fraction by health district of residence within the Local Health Unit (LHU) N. 8 of Sardinia. With reference to the age and gender-specific hospitalization rates of the whole LHU, residents in the urban Cagliari health district showed an excess risk of haemolymphopoietic cancer (RR = 1.07; 95% CI 1.03-1.12) and bladder cancer (RR = 1.10; 95% CI 1.05-1.16); in both instances, risks were higher among female residents. The highest excess risk for lung cancer was observed among residents in the Quartu-Parteolla health district (RR = 1.13; 95% CI 1.05-1.21), and it was slightly higher among male residents. The results appear to confirm the role of urban factors in increasing cancer risk.

    Full Text Available Abstract Background Current epidemiological data highlight the potential detrimental associations between sedentary behaviours and health outcomes, yet little is known about temporal trends in adult sedentary time. This study used time use data to examine population trends in sedentary behaviours in non-occupational domains and more specifically during leisure time. Methods We conducted secondary analysis of population representative data from the Australian Time Use Surveys 1992, 1997 and 2006 involving respondents aged 20 years and over with completed time use diaries for two days. Weighted samples for each survey year were: n = 5851 (1992, n = 6419 (1997 and n = 5505 (2006. We recoded all primary activities by domain (sleep, occupational, transport, leisure, household, education and intensity (sedentary, light, moderate. Adjusted multiple linear regressions tested for differences in time spent in non-occupational sedentary behaviours in 1992 and 1997 with 2006 as the reference year. Results Total non-occupational sedentary time was slightly lower in 1997 than in 2006 (mean = 894 min/2d and 906 min/2d, respectively; B = −11.2; 95%CI: -21.5, -0.9. Compared with 2006, less time was spent in 1997 in sedentary transport (B-6.7; 95%CI: -10.4, -3.0 and sedentary education (B = −6.3; 95%CI: -10.5, -2.2 while household and leisure sedentary time remained stable. Time engaged in different types of leisure-time sedentary activities changed between 1997 and 2006: leisure-time computer use increased (B = −26.7; 95%CI: -29.5, -23.8, while other leisure-time sedentary behaviours (e.g., reading, listening to music, hobbies and crafts showed small concurrent reductions. In 1992, leisure screen time was lower than in 2006: TV-viewing (B = −24.2; 95%CI: -31.2, -17.2, computer use (B = −35.3; 95%CI: -37.7, -32.8.

    This study discusses the workplace ergonomic issues in highway construction, and the safe work practices associated with the prevention of ergonomic-related injuries and illnesses in the construction field. In order to achieve the study objectives, a survey was designed and sent to Wisconsin based construction contractors. To design an adequate questionnaire, the research team first conducted a pilot study. The findings from the pilot survey provided a clear direction in creating the final survey. The survey results indicated that hand and finger injuries due to cutting operations and back injuries due to the manual handling of heavy materials to be the most frequent construction task/injury combination. All of the construction firms surveyed had a safety program; however, most of the contractors did not have a site-specific ergonomics program. The construction workers were usually walking/working on the ground, ladder and scaffold, and spent significant amount of time for the manual lifting or carrying heavy materials. The findings from this study may assist safety and health professionals in the construction industry in making effective changes for improving health and productivity.

    The advancement of the photovoltaic technology is closely linked to the standard evaluation of the product, the diagnosis of problems, the validation of materials and cell properties, and the engineering and documentation of the ensemble of device properties from internal interfaces through power outputs. The focus of this paper is on some of the more common, visible, and important techniques dealing with physical-chemical through electro-optical parameters, which are linked intimately to the performance quality of materials and devices. Two areas, defined by their spatial-resolution qualities, are emphasized: macroscale and microscale measurement technologies. The importance, strengths, and limitations of these techniques are stressed, especially their significance to photovoltaics. Included are several techniques that have been developed specifically to address problems and requirements for photovoltaics. The regime of measurement literally covers arrays through atoms. {copyright} {ital 1998 Materials Research Society.}

    2011-01-01

    Full Text Available Introduction: Hand splinting after stroke is a common practice despite inadequate evidence. This warrants a better understanding of the therapists′ splinting practice, to develop clinically meaningful treatment options. Aims: The study examined the nature and prevalence of the factors associated with therapists′ hand splinting practice and their perceived splinting efficacy. Settings and Design: A cross-sectional national survey of hand-splinting practice among inpatient occupational therapists (OTs in Ireland. Materials and Methods: Sixty-two therapists participated in this national survey.Statistical analysis used: A number of factors were analyzed to explore their relationship with therapists′ perception of splint efficacy using Spearman′s rank order correlation. Results: 53(85.5% out of 62 survey respondents prescribed splints to their clients at the time of taking the survey. To reduce spasticity, to correct contractures and thus increase range of motion (ROM were the commonly used splinting goals. These were the goals that were significantly associated with the therapists′ splinting efficacy too. Conclusions: Hand-splint prescription following stroke was found to be a common practice among OTs who perceive splints to be quite effective. A custom-made, volar forearm-based wrist-hand splint is the preferred splint among therapists to achieve a number of clinical aims such as improving ROM, stretching soft tissue contractures and reducing spasticity in the upper extremity. A wide variety of splinting regimens is currently practiced, reflecting the lack of a universally accepted and comprehensive practice guideline to regulate therapy. Methodologically valid clinical trials evaluating the efficacy of therapist-preferred splints in achieving their favored outcomes are needed. Development of common, universally accepted therapeutic guidelines based on comprehensive scientific review of such studies is thus needed.

    Full Text Available Wild elephants represent the biggest human–wildlife conflict issue in Livingstone, Zambia. However, little is known about their movements. This survey investigated elephants’ habitat use outside a core protected and fenced zone that forms part of Mosi-oa-Tunya National Park, Zambia. Using ‘patch-occupancy’ methodology, indications of elephant presence (feeding behaviour, dung and tracks were surveyed. The survey aimed to assist proposed future monitoring exercises by defining the geographical extent that should be considered to improve accuracy in species abundance estimates. Results were supplemented using collected indications of elephant presence from prior monitoring exercises, and during this survey. Elephant presence was confirmed up to 8 km from the boundary of the protected core habitat, focussed in: (1 an unfenced zone of the national park, (2 along a road leading from the national park to the Dambwa Forest to the north and (3 along two rivers located to the west (Sinde River and east (Maramba River of the core area. Detection probability of elephant presence was high using these methods, and we recommend regular sampling to determine changes in habitat use by elephants, as humans continue to modify land-use patterns.Conservation implications: Identification of elephant ranging behaviour up to 8 km outside of the Mosi-oa-Tunya National Park in southern Zambia will assist in managing human– elephant conflict in the area, as well as in assessing this seasonal population’s abundance.

    Full Text Available To compare the performance of the active short-term and passive long-term radon measurement methods, a study was carried out in several closed spaces, including a uranium mine in Iran. For the passive method, solid-state nuclear track detectors based on Lexan polycarbonate were utilized, for the active method, AlphaGUARD. The study focused on the correlation between the results obtained for estimating the average indoor radon concentrations and consequent personal occupational doses in various working places. The repeatability of each method was investigated, too. In addition, it was shown that the radon concentrations in different stations of the continually ventilated uranium mine were comparable to the ground floor laboratories or storage rooms (without continual ventilation and lower than underground laboratories.

    Spatial configurations of office environments assessed by Space Syntax methodologies are related to employee movement patterns. These methods require analysis of floors plans which are not readily available in large population-based studies or otherwise unavailable. Therefore a self-report instrument to assess spatial configurations of office environments using four scales was developed. The scales are: local connectivity (16 items), overall connectivity (11 items), visibility of co-workers (10 items), and proximity of co-workers (5 items). A panel cohort (N = 1154) completed an online survey, only data from individuals employed in office-based occupations (n = 307) were used to assess scale measurement properties. To assess test-retest reliability a separate sample of 37 office-based workers completed the survey on two occasions 7.7 (±3.2) days apart. Redundant scale items were eliminated using factor analysis; Chronbach's α was used to evaluate internal consistency and test re-test reliability (retest-ICC). ANOVA was employed to examine differences between office types (Private, Shared, Open) as a measure of construct validity. Generalized Linear Models were used to examine relationships between spatial configuration scales and the duration of and frequency of breaks in occupational sitting. The number of items on all scales were reduced, Chronbach's α and ICCs indicated good scale internal consistency and test re-test reliability: local connectivity (5 items; α = 0.70; retest-ICC = 0.84), overall connectivity (6 items; α = 0.86; retest-ICC = 0.87), visibility of co-workers (4 items; α = 0.78; retest-ICC = 0.86), and proximity of co-workers (3 items; α = 0.85; retest-ICC = 0.70). Significant (p ≤ 0.001) differences, in theoretically expected directions, were observed for all scales between office types, except overall connectivity. Significant associations were observed between all scales and occupational sitting behaviour (p ≤ 0.05). All scales have

  6. MEASUREMENT OF FRICTIONAL PRESSURE DIFFERENTIALS DURING A VENTILATION SURVEY

    Energy Technology Data Exchange (ETDEWEB)

    B.S. Prosser, PE; I.M. Loomis, PE, PhD

    2003-11-03

    During the course of a ventilation survey, both airflow quantity and frictional pressure losses are measured and quantified. The measurement of airflow has been extensively studied as the vast majority of ventilation standards/regulations are tied to airflow quantity or velocity. However, during the conduct of a ventilation survey, measurement of airflow only represents half of the necessary parameters required to directly calculate the airway resistance. The measurement of frictional pressure loss is an often misunderstood and misapplied part of the ventilation survey. This paper compares the two basic methods of frictional pressure drop measurements; the barometer and the gauge and tube. Personal experiences with each method will be detailed along with the authors' opinions regarding the applicability and conditions favoring each method.

    The accuracy and repeatability of an inertial measurement unit (IMU) system for directly measuring trunk angular displacement and upper arm elevation were evaluated over eight hours (i) in comparison to a gold standard, optical motion capture (OMC) system in a laboratory setting, and (ii) during a field-based assessment of dairy parlour work. Sample-to-sample root mean square differences between the IMU and OMC system ranged from 4.1° to 6.6° for the trunk and 7.2°-12.1° for the upper arm depending on the processing method. Estimates of mean angular displacement and angular displacement variation (difference between the 90th and 10th percentiles of angular displacement) were observed to change IMU system may serve as an acceptable instrument for directly measuring trunk and upper arm postures in field-based occupational exposure assessment studies with long sampling durations. Practitioner Summary: Few studies have evaluated inertial measurement unit (IMU) systems in the field or over long sampling durations. Results of this study indicate that the IMU system evaluated has reasonably good accuracy and repeatability for use in a field setting over a long sampling duration.

    To investigate the association between occupational contamination and exposure levels to antineoplastic drugs and the application of control measures in a hospital work environment. Wipe samples of equipments were collected at a hospital in Osaka Prefecture, Japan, from 2007 to 2011. These samples were subjected to measurements of cyclophosphamide (CP), gemcitabine (GEM), platinum-containing drugs (Pt), and fluorouracil (5FU). Additionally, 24-h urine samples were collected from pharmacists who handled antineoplastic drugs, which were analyzed for CP and alpha-fluoro-beta-alanine (AFBA). The application of control measures was scored according to a checklist, which consisted of the following five items: safety equipment and maintenance, training and documentation, devices for safe handling, personal protective equipment, and emergency care. The aim was to obtain a score of 80%. The median CP, GEM, and 5FU concentrations of all wipe samples were significantly lower during the period when the mean score was >80% (attainment period) versus when the mean score was ≤80% (nonattainment period; all P antineoplastic drugs decreased with a score higher than 80%. The scores of the items on the checklist appeared to adequately reflect the condition of the control measures, as increases in all five items were associated with reductions in the contamination by and levels of exposure to all drugs.

    OBJECTIVE. The objectives of this study were to better understand the cognitive profile of adults with attention deficit hyperactivity disorder (ADHD), their occupational performance, and their quality of life (QoL) and to examine the validity of a cognitive-functional evaluation (CFE) battery for these adults. METHOD. Eighty-one adults with ADHD and 58 without ADHD completed ADHD symptom ratings, the Behavior Rating Inventory of Executive Function-Adult Version, and the Adult ADHD Quality-of-Life Scale. An occupational performance interview was administered to the ADHD group. RESULTS. A broad range of occupational concerns were reported. We found significant differences between groups on all measures. In the ADHD group, we found medium significant correlations among the measures. CONCLUSION. Adults with ADHD experience cognitive and functional difficulties in their daily lives associated with QoL. The results support the use of a CFE battery that has been shown to be sensitive and specific for these adults.

    2010-02-01

    Full Text Available The binary feature vector is one of the most common representations of patterns and measuring similarity and distance measures play a critical role in many problems such as clustering, classification, etc. Ever since Jaccard proposed a similarity measure to classify ecological species in 1901, numerous binary similarity and distance measures have been proposed in various fields. Applying appropriate measures results in more accurate data analysis. Notwithstanding, few comprehensive surveys on binary measures have been conducted. Hence we collected 76 binary similarity and distance measures used over the last century and reveal their correlations through the hierarchical clustering technique.

    The intake of radioactive material by workers can occur in the radiopharmaceuticals production, during the handling of these in the medical fields (nuclear medicine) and in biological and research laboratories. The workers who work in areas where exposures are significant are routinely monitored to demonstrate that the workers are receiving adequate protection from internal contamination. Direct measurements of whole-body and thyroid contents provide an estimate of the activity of these radionuclides in the potentially exposed workers. The whole-body measurements of the workers, trainees and visitors are routinely performed by the In Vivo Monitoring Laboratory (LMIV) of the Energy and Nuclear Research Institute (IPEN/CNEN-SP). The frequency of measurements is defined by the Radioprotection Service (SRP) and the Dose Calculation Group of IPEN. For this purpose LMIV has two counters, whole body. NaITl (8 x 4”), and thyroid one, NaITl (3 x 3”). The system was calibrated in energy and efficiency, with calibration sources of Eu-152, Am-241 and Co-60 with gamma emissions between 59.54 and 1408.08 keV, positioned within Alderson Research Labs. anthropomorphic phantom. The background measures were obtained of worker's spectrum that was not exposed occupationally yet. The concepts adopted in the HPS N13.30 Standard and proposed in ISO documents for standardization were used for activity measurements. During the period January 2010 to December 2014, approximately 4500 measurements had been carried in workers who develop tasks related to the production and research. The activities of the radionuclides and the workers' tasks relationship had been evaluated. (author)

    Addressing social determinants in the field of tuberculosis (TB) has received great attention in the past years, mainly due to the fact that worldwide TB incidence has not declined as much as expected, despite highly curative control strategies. One of the objectives of the World Health Organization Global Task Force on TB Impact Measurement is to assess the prevalence of TB disease in 22 high-burden countries by active screening of a random sample of the general population. These surveys provide a unique opportunity to assess socio-economic determinants in relation to prevalent TB and its risk factors. This article describes methods of measuring the socio-economic position in the context of a TB prevalence survey. An indirect measurement using an assets score is the most feasible way of doing this. Several examples are given from recently conducted prevalence surveys of the use of an assets score, its construction, and the analyses of the obtained data.

    We present the first regional trends in anuran occupancy from North American Amphibian Monitoring Program (NAAMP) data from 11 northeastern states using an 11 years of data. NAAMP is a long-term monitoring program where observers collect data at assigned random roadside routes using a calling survey technique. We assessed occupancy trends for 17 species. Eight species had statistically significant regional trends, of these seven were negative (Anaxyrus fowleri, Acris crepitans, Pseudacris brachyphona, Pseudacris feriarum-kalmi complex, Lithobates palustris, Lithobates pipiens, and Lithobates sphenocephalus) and one was positive (Hyla versicolor-chrysoscelis complex). We also assessed state level trends for 101 species/state combinations, of these 29 showed a significant decline and nine showed a significant increase in occupancy.

    In patient-centered practice, instruments need to assess outcomes that are meaningful to patients with hand conditions. It is unclear which assessment tools address these subjective perspectives best. The aim of this study was to establish the construct validity of the Canadian Occupational Performance Measure (COPM) in relation to the Disabilities of Arm, Shoulder, and Hand (DASH) questionnaire and the Michigan Hand Outcomes Questionnaire (MHQ) in people with hand conditions. It was hypothesized that COPM scores would correlate with DASH and MHQ total scores only to a moderate degree and that the COPM, DASH questionnaire, and MHQ would all correlate weakly with measures of hand impairments. This was a validation study. The COPM, DASH questionnaire, and MHQ were scored, and then hand impairments were measured (pain [numerical rating scale], active range of motion [goniometer], grip strength [dynamometer], and pinch grip strength [pinch meter]). People who had received postsurgery rehabilitation for flexor tendon injuries, extensor tendon injuries, or Dupuytren disease were eligible. Seventy-two participants were included. For all diagnosis groups, the Pearson coefficient of correlation between the DASH questionnaire and the MHQ was higher than .60, whereas the correlation between the performance scale of the COPM and either the DASH questionnaire or the MHQ was lower than .51. Correlations of these assessment tools with measures of hand impairments were lower than .46. The small sample sizes may limit the generalization of the results. The results supported the hypotheses and, thus, the construct validity of the COPM after surgery in people with hand conditions. © 2015 American Physical Therapy Association.

  1. Using areas of known occupancy to identify sources of variation in detection probability of raptors: taking time lowers replication effort for surveys.

    Species occurring at low density can be difficult to detect and if not properly accounted for, imperfect detection will lead to inaccurate estimates of occupancy. Understanding sources of variation in detection probability and how they can be managed is a key part of monitoring. We used sightings data of a low-density and elusive raptor (white-headed vulture Trigonoceps occipitalis) in areas of known occupancy (breeding territories) in a likelihood-based modelling approach to calculate detection probability and the factors affecting it. Because occupancy was known a priori to be 100%, we fixed the model occupancy parameter to 1.0 and focused on identifying sources of variation in detection probability. Using detection histories from 359 territory visits, we assessed nine covariates in 29 candidate models. The model with the highest support indicated that observer speed during a survey, combined with temporal covariates such as time of year and length of time within a territory, had the highest influence on the detection probability. Averaged detection probability was 0.207 (s.e. 0.033) and based on this the mean number of visits required to determine within 95% confidence that white-headed vultures are absent from a breeding area is 13 (95% CI: 9-20). Topographical and habitat covariates contributed little to the best models and had little effect on detection probability. We highlight that low detection probabilities of some species means that emphasizing habitat covariates could lead to spurious results in occupancy models that do not also incorporate temporal components. While variation in detection probability is complex and influenced by effects at both temporal and spatial scales, temporal covariates can and should be controlled as part of robust survey methods. Our results emphasize the importance of accounting for detection probability in occupancy studies, particularly during presence/absence studies for species such as raptors that are widespread and

    1977-10-01

    From the Third National Cancer Survey (TNCS) Interview Study of 7,518 incident cases, lifetime histories of occupations and industries were studied for associations with specific cancer sites and types while controlling for age, sex, race, education, use of cigarettes or alcohol, and geographic location. Lung cancer patients were found more often than expected among several categories including trucking, air transportation, wholesaling, painting, building construction, building maintenance, and manufacturing (furniture, transportation equipment, and food products). Controlling for cigarette smoking did not change these associations. Leukemia and multiple myeloma were associated with sales personnel of both sexes, whereas lymphomas and Hodgkin's disease were excessive among women working in the medical industry. Other associations included rectal cancer with several retail industries; prostate cancer with ministers, farmers, plumbers, and coal miners; malignant melanoma with school teachers; and invasive cervical cancer with women working in hotels and restaurants. Breast cancer patients were more common among women who were teachers or other professionals and who worked in business and finance (even after controlling for education). Many other findings are presented in detailed tables. Results are reported mainly as a research resource for use by other investigators doing work in this field. Suggestions are given for future studies.

  3. Individual Social Capital and Its Measurement in Social Surveys

    Directory of Open Access Journals (Sweden)

    Keming Yang

    2007-01-01

    Full Text Available With its popularity has come an unresolved issue about social capital: is it an individual or a collective property, or both? Many researchers take it for granted that social capital is collective, but most social surveys implicitly measure social capital at the individual level. After reviewing the definitions by Bourdieu, Coleman, and Putnam, I become to agree with Portes that social capital can be an individual asset and should be firstly analyzed as such; if social capital is to be analyzed as a collective property, then the analysis should explicitly draw on a clear definition of individual social capital. I thus define individual social capital as the features of social groups or networks that each individual member can access and use for obtaining further benefits. Four types of features are identified (basic, specific, generalized, and structural, and example formulations of survey questions are proposed. Following this approach, I then assess some survey questions organized under five themes commonly found in social surveys for measuring social capital: participation in organizations, social networks, trust, civic participation, and perceptions of local area. I conclude that most of these themes and questions only weakly or indirectly measure individual social capital; therefore, they should be strengthened with the conceptual framework proposed in this paper and complemented with the items used in independent surveys on social networks.

  4. Measuring Nonresponse Bias in a Cross-Country Enterprise Survey

    2015-04-01

    Full Text Available Nonresponse is a common issue affecting the vast majority of surveys. Efforts to convince those unwilling to participate in a survey might not necessary result in a better picture of the target population and can lead to higher, not lower, nonresponse bias.We investigate the impact of non-response in the European Commission & European Central Bank Survey on the Access to Finance of Enterprises (SAFE, which collects evidence on the financing conditions faced by European SMEs compared with those of large firms. This survey, conducted by telephone bi-annually since 2009 by the ECB and the European Commission, provides a valuable means to search for this kind of bias, given the high heterogeneity of response propensities across countries.The study relies on so-called “Representativity Indicators” developed within the Representativity Indicators of Survey Quality (RISQ project, which measure the distance to a fully representative response. On this basis, we examine the quality of the SAFE Survey at different stages of the fieldwork as well as across different survey waves and countries. The RISQ methodology relies on rich sampling frame information, which is however partly limited in the case of the SAFE. We also assess the representativeness of the SAFE particular subsample created by linking the survey responses with the companies’ financial information from a business register; this sub-sampling is another potential source of bias which we also attempt to quantify. Finally, we suggest possible ways how to improve monitoring of the possible nonresponse bias in the future rounds of the survey.

  5. Working meeting on blood pressure measurement: suggestions for measuring blood pressure to use in populations surveys.

    2003-11-01

    As part of the Pan American Hypertension Initiative (PAHI), the Pan American Health Organization and the National Heart, Lung, and Blood Institute of the National Institutes of Health of the United States of America conducted a working meeting to discuss blood pressure (BP) measurement methods used in various hypertension prevalence surveys and clinical trials, with the objective of developing a BP measurement protocol for use in hypertension prevalence surveys in the Americas. No such common protocol has existed in the Americas, so it has been difficult to compare hypertension prevention and intervention strategies. This piece describes a proposed standard method for measuring blood pressure for use in population surveys in the Region of the Americas. The piece covers: considerations for developing a common blood pressure measurement protocol, critical issues in measuring blood pressure in national surveys, minimum procedures for blood pressure measurement during surveillance, and quality assessment of blood pressure.

    2005-07-01

    Contributing factors to 621 occupational fatal falls have been identified with respect to the victim's individual factors, the fall site, company size, and cause of fall. Individual factors included age, gender, experience, and the use of personal protective equipment (PPE). Accident scenarios were derived from accident reports. Significant linkages were found between causes for the falls and accident events. Falls from scaffold staging were associated with a lack of complying scaffolds and bodily action. Falls through existing floor openings were associated with unguarded openings, inappropriate protections, or the removal of protections. Falls from building girders or other structural steel were associated with bodily actions and improper use of PPE. Falls from roof edges were associated with bodily actions and being pulled down by a hoist, object or tool. Falls through roof surfaces were associated with lack of complying scaffolds. Falls from ladders were associated with overexertion and unusual control and the use of unsafe ladders and tools. Falls down stairs or steps were associated with unguarded openings. Falls while jumping to a lower floor and falls through existing roof openings were associated with poor work practices. Primary and secondary prevention measures can be used to prevent falls or to mitigate the consequences of falls and are suggested for each type of accident. Primary prevention measures would include fixed barriers, such as handrails, guardrails, surface opening protections (hole coverings), crawling boards/planks, and strong roofing materials. Secondary protection measures would include travel restraint systems (safety belt), fall arrest systems (safety harness), and fall containment systems (safety nets).

    2017-09-06

    The construction industry is an important sector of the economy in Poland. According to the National Labour Inspectorate (PIP) data of 2014, the number of victims of fatal accidents in the construction sector amounted to 80 as compared with 187 injured in all other sectors of economy in Poland. This paper presents the results of surveys on the impact of construction worker behaviour on the occupational safety and health outcomes. The surveys took into account the point of view of both construction site management (tactical level) and construction workers (operational level). For the analysis of results, the method of numerical taxonomy and Pareto charts was employed, which allowed the authors to identify the areas of occupational safety and health at both an operational and tactical level, in which improvement actions needed to be proposed for workers employed in micro, small, medium and large construction enterprises.

    In the empirical literature on work experience, job tenure, training and earnings, only one previous study has made a distinction between the effects of work experience in the current occupation and work experience in previous ones, and no study has made the distinction with respect to training. Yet it is reasonable to hypothesize that the distinction is important. Using data from the US National Longitudinal Survey of Youth, it is found that the returns to work experience in the current occu...

    The objective of this study is to estimate occupational differences in self-rated health, both in cross-section and over time, among older individuals. We use hierarchical linear models to estimate self-reported health as a function of 8 occupational categories and key covariates. We examine self-reported health status over 7 waves (12 years) of the Health and Retirement Study. Our study sample includes 9,586 individuals with 55,389 observations. Longest occupation is used to measure the cumulative impact of occupation, address the potential for reverse causality, and allow the inclusion of all older individuals, including those no longer working. Significant baseline differences in self-reported health by occupation are found even after accounting for demographics, health habits, economic attributes, and employment characteristics. But contrary to our hypothesis, there is no support for significant differences in slopes of health trajectories even after accounting for dropout. Our findings suggest that occupation-related differences found at baseline are durable and persist as individuals age.

    2009-06-01

    We developed and pilot-tested an overall protocol for intervention studies to evaluate the effects of indoor environmental changes in office buildings on the health symptoms and comfort of occupants. The protocol includes a web-based survey to assess the occupant's responses, as well as specific features of study design and analysis. The pilot study, carried out on two similar floors in a single building, compared two types of ventilation system filter media. With support from the building's Facilities staff, the implementation of the filter change intervention went well. While the web-based survey tool worked well also, low overall response rates (21-34percent among the three work groups included) limited our ability to evaluate the filter intervention., The total number of questionnaires returned was low even though we extended the study from eight to ten weeks. Because another simultaneous study we conducted elsewhere using the same survey had a high response rate (>70percent), we conclude that the low response here resulted from issues specific to this pilot, including unexpected restrictions by some employing agencies on communication with occupants.

    Green, Sarah H; Glanz, Karen

    2015-07-01

    Objective, observational measures of nutrition environments are now well established and widely used. Individuals' perceptions of their nutrition environments may be equally or more important, but are less well conceptualized, and comprehensive measures are not available. This paper describes the development of the Perceived Nutrition Environment Measures Survey (NEMS-P), its test-retest reliability, and its ability to discern differences between lower- and higher-SES neighborhoods. This research involved five steps: (1) development of a conceptual model and inventory of items; (2) expert review; (3) pilot testing and cognitive interviews; (4) revising the survey; and (5) administering the revised survey to participants in neighborhoods of high and low SES on two occasions to evaluate neighborhood differences and test-retest reliability. Data were collected in 2010 and 2011 and analyzed in 2011 and 2012. The final survey has 118 items. Fifty-three core items represent three types of perceived nutrition environments: community nutrition environment, consumer nutrition environment, and home food environment. Test-retest reliability for core constructs of perceived nutrition environments was moderate to good (0.52-0.83) for most measured constructs. Residents of higher-SES neighborhoods reported higher availability scores in stores, stronger agreement that healthy options were available in nearby restaurants, and higher scores for accessibility of healthy foods in their homes. The NEMS-P has moderate to good test-retest reliability and can discriminate perceptions of nutrition environments between residents of higher- and lower-SES neighborhoods. This survey is available and ready to be used. Copyright © 2015 American Journal of Preventive Medicine. Published by Elsevier Inc. All rights reserved.

    Full Text Available This paper presents results from spectrum occupancy measurements in the 2.3-2.4 GHz band at Turku, Finland. The band is currently under study in European regulation and standardization for mobile communication systems. We review the recently introduced Licensed Shared Access (LSA concept as a potential means for making the 2.3-2.4 GHz band available for mobile communications on a shared basis while protecting the rights of the incumbent spectrum users. The spectrum occupancy measurements conducted in one location in Finland show that the use of this band is rather low indicating that there might be potential for mobile communication systems to share this band with the incumbents under the LSA approach. Based on the obtained knowledge about the use of the studied band in Finland we create a set of guidelines for LSA to make the operation efficient both from the technical and economic viewpoint.

  17. Survey of spectral response measurements for photovoltaic devices

    Energy Technology Data Exchange (ETDEWEB)

    Hartman, J.S.; Lind, M.A.

    1981-11-01

    A survey of the photovoltaic community was conducted to ascertain the present state-of-the-art for PV spectral response measurements. Specific topics explored included measurement system designs, good and bad features of the systems, and problems encountered in the evaluation of specific cell structures and materials. The survey showed that most spectral response data are used in diagnostic analysis for the optimization of developmental solar cells. Measurement systems commonly utilize a chopped narrowband source in conjunction with a constant bias illumination which simulates the ambient end use environment. Researchers emphasized the importance of bias illumination for all types of cells in order to minimize the effects of nonlinearities in cell response. Not surprisingly single crystal silicon cells present the fewest measurement problems to the researcher and have been studied more thoroughly than any other type of solar cell. But, the accurate characterization of silicon cells is still difficult and laboratory intercomparison studies have yielded data scatter ranging from +-5% to +-15%. The measurement experience with other types of cells is less extensive. The development of reliable data bases for some solar cells is complicated by problems of cell nonuniformity, environmental instability, nonlinearity, etc. Cascade cells present new problems associated with their structue (multiple cells in series) which are just beginning to be understood. In addition, the importance of many measurement parameters (spectral content of bias light, bias light intensity, bias voltage, chopping frequency, etc.) are not fully understood for most types of solar cells.

    2017-02-01

    Full Text Available The Open Geospatial Consortium (OGC is committed to developing quality open standards for the global geospatial community, thus enhancing the interoperability of geographic information. In the domain of sensor networks, the Sensor Web Enablement (SWE initiative has been developed to define the necessary context by introducing modeling standards, like ‘Observation & Measurement’ (O&M and services to provide interaction like ‘Sensor Observation Service’ (SOS. Land surveying measurements on the other hand comprise a domain where observation information structures and services have not been aligned to the OGC observation model. In this paper, an OGC-compatible, aligned to the ‘Observation and Measurements’ standard, model for land surveying observations has been developed and discussed. Furthermore, a case study instantiates the above model, and an SOS implementation has been developed based on the 52° North SOS platform. Finally, a visualization schema is used to produce ‘Web Map Service (WMS’ observation maps. Even though there are elements that differentiate this work from classic ‘O&M’ modeling cases, the proposed model and flows are developed in order to provide the benefits of standardizing land surveying measurement data (cost reducing by reusability, higher precision level, data fusion of multiple sources, raw observation spatiotemporal repository access, development of Measurement-Based GIS (MBGIS to the geoinformation community.

  19. Can A Galaxy Redshift Survey Measure Dark Energy Clustering?

    CERN Document Server

    2006-01-01

    (abridged) A wide-field galaxy redshift survey allows one to probe galaxy clustering at largest spatial scales, which carries an invaluable information on horizon-scale physics complementarily to the cosmic microwave background (CMB). Assuming the planned survey consisting of z~1 and z~3 surveys with areas of 2000 and 300 square degrees, respectively, we study the prospects for probing dark energy clustering from the measured galaxy power spectrum, assuming the dynamical properties of dark energy are specified in terms of the equation of state and the effective sound speed c_e in the context of an adiabatic cold dark matter (CDM) model. The dark energy clustering adds a power to the galaxy power spectrum amplitude at spatial scales greater than the sound horizon, and the enhancement is sensitive to redshift evolution of the net dark energy density, i.e. the equation of state. We find that the galaxy survey, when combined with Planck, can distinguish dark energy clustering from a smooth dark energy model such ...

    van Dierendonck, Dirk; Nuijten, Inge

    2011-09-01

    PURPOSE: The purpose of this paper is to describe the development and validation of a multi-dimensional instrument to measure servant leadership. DESIGN/METHODOLOGY/APPROACH: Based on an extensive literature review and expert judgment, 99 items were formulated. In three steps, using eight samples totaling 1571 persons from The Netherlands and the UK with a diverse occupational background, a combined exploratory and confirmatory factor analysis approach was used. This was followed by an analysis of the criterion-related validity. FINDINGS: The final result is an eight-dimensional measure of 30 items: the eight dimensions being: standing back, forgiveness, courage, empowerment, accountability, authenticity, humility, and stewardship. The internal consistency of the subscales is good. The results show that the Servant Leadership Survey (SLS) has convergent validity with other leadership measures, and also adds unique elements to the leadership field. Evidence for criterion-related validity came from studies relating the eight dimensions to well-being and performance. IMPLICATIONS: With this survey, a valid and reliable instrument to measure the essential elements of servant leadership has been introduced. ORIGINALITY/VALUE: The SLS is the first measure where the underlying factor structure was developed and confirmed across several field studies in two countries. It can be used in future studies to test the underlying premises of servant leadership theory. The SLS provides a clear picture of the key servant leadership qualities and shows where improvements can be made on the individual and organizational level; as such, it may also offer a valuable starting point for training and leadership development.

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

    The selective serotonin reuptake inhibitor (SSRI) citalopram (R,S-citalopram) is a racemic compound of two enantiomers. On the basis of in-vitro studies, inhibition of the human serotonin transporter (5-HTT) is achieved by the S-enantiomer (S-citalopram or escitalopram). The aim of the present PET study was to compare 5-HTT occupancy after single equimolar doses (with respect to S-enantiomer) in humans in vivo using R,S-citalopram (20 mg) and S-citalopram (10 mg) using PET and the radioligand [(11)C]MADAM. The design was a single-dose, double-blind, two-way crossover study in eight healthy male subjects. The 5-HTT binding potential at baseline and after single doses of study drugs was used to calculate 5-HTT occupancy in seven brain regions. Serum concentrations of the study drugs were determined in order to calculate the apparent inhibition constant (K(i),(app)), a secondary parameter of interest for the comparison. In all brain regions examined, occupancy was numerically higher after treatment with R,S-citalopram [66+/-19% to 78+/-17% (mean+/-s.d.) depending on the region] than after S-citalopram (59+/-15% to 69+/-13%; overall comparison: F=14.8, d.f.=1, 90, p<0.001). In line with this the apparent inhibition constant was significantly lower for R,S-citalopram than for S-citalopram (overall comparison: F=6.7, d.f.=1, 90, p<0.05). The small but significant difference in occupancy and K(i),(app) found between R,S-citalopram and S-citalopram suggests that not only S-citalopram but also R-citalopram to some degree occupies the 5-HTT in the human brain in vivo.

    Simultaneous personal measurements of the occupational ultraviolet exposure weighted to the International Commission on Non-Ionising Radiation Protection hazard sensitivity spectrum (UVICNIRP) were made over a five week period (44 person-days) in the second half of the summer school term of 2012 in Queensland, Australia for individual high school teachers located at latitudes of 27.5°S and 23.5°S. These teachers were employed for the duration of the study in a predominately indoor classroom teaching role, excluding mandatory periods of lunch time yard duty and school sport supervisions. Data is presented from personal measurements made to the shirt collar using polyphenylene oxide (PPO) film UV dosimeters. UVICNIRP exposure data is presented for each week of the study period for the shirt collar measurement site and are further expressed relative to the measured ambient horizontal plane exposure. Personal exposures were correlated with time outdoors, showing a higher exposure trend on days when teachers were required to supervise outdoor areas for more than 2h per week (mean daily exposure: 168Jm(-2)UVICNIRP±5Jm(-2) (1σ)) compared to the study average (mean daily exposure: 115Jm(-2)UVICNIRP±91Jm(-2) (1σ)). Time spent in an open playground environment was found to be the most critical factor influencing the occupational UVICNIRP exposure. A linear model was developed showing a correlation (R(2)=0.77) between the time teachers spent on yard duty and UVICNIRP exposure, expressed relative to ambient. The research findings indicate a greater reduction in personal exposure can be achieved by timetabling for yard duty periods in playground areas which offer more shade from trees and surrounding buildings. All mean daily personal exposures measured at the shirt collar site were higher than the ICNIRP occupational daily exposure limit of 30Jm(-2) for outdoor workers.

    Full Text Available The aim of this prospective study was to explore predictors of objective career success among Swedish women and men, focussing on gender differences. Data were drawn from the 2008 and 2010 waves of the Swedish Longitudinal Occupational Survey of Health (SLOSH with a total of 3670 female and 2773 male participants. Odds ratios and 95% confidence intervals for job promotion and an above-average salary increase between 2008 and 2010 were obtained through binary logistic regression analyses. Individual and organisational factors measured in 2008 were used as predictors in analyses stratified by sex. Mutual adjustment was performed for these variables, as well as for labour market sector and staff category at baseline. In both sexes, younger age predicted both job promotion and an above-average salary increase. Job promotion was also in both sexes predicted by being part of decision-making processes, having conflicts with superiors, and being eager to advance. Furthermore, promotion was predicted by, among men, being educated to post-graduate level and having an open coping strategy and, among women, working >60 hours/week. An above-average salary increase was predicted in both sexes by having a university education. Postgraduate education, having children living at home, and being very motivated to advance predicted an above-average salary increase among women, as did working 51-60 hours/week and being part of decision-making processes in men. Gender differences were seen in several predictors. In conclusion, the results support previous findings of gender differences in predictors of career success. A high level of education, motivation to advance, and procedural justice appear to be more important predictors of career success among women, while open coping was a more important predictor among men.

    Full Text Available Microwaves are radio waves with wavelengths ranging from as long as one meter to as short as one millimeter, or equivalently, with frequencies between 300 MHz and 300 GHz. The science of photonics includes the generation, emission, modulation, signal processing, switching, transmission, amplification, detection and sensing of light. Microwave photonics has been introduced for achieving ultra broadband signal processing. Instantaneous Frequency Measurement (IFM receivers play an important role in electronic warfare. Technologies used for signal processing, include conventional direct Radio Frequency (RF techniques, digital techniques, intermediate frequency (IF techniques and photonic techniques. Direct RF techniques suffer an increased loss, high dispersion, and unwanted radiation problems in high frequencies. The systems that use traditional RF techniques can be bulky and often lack the agility required to perform advanced signal processing in rapidly changing environments. In this paper we discussed a survey of Microwave Frequency Measurement Techniques. The microwaves techniques are categorized based upon different approaches. This paper provides the major advancement in the Microwave Frequency MeasurementTechniques research; using these approaches the features and categories in the surveyed existing work.

    The Second Military Survey of the Habsburg Empire, completed in the 19th century, can be very useful in different scientific investigations owing to its accuracy and data content. The fact, that the mapmakers used geodetic projection, and the high accuracy of the survey guarantee that scientists can use these maps and the represented objects can be evaluated in retrospective studies. Among others, the hydrological information of the map sheets is valuable. The streams were drawn with very thin lines that also ascertain the high accuracy of their location, provided that the geodetic position of the sheet can be constructed with high accuracy. After geocoding these maps we faced the high accuracy of line elements. Not only the location of these lines but the form of the creeks are usually almost the same as recent shape. The goal of our study was the neotectonic evaluation of the western part of the Pannonian Basin, bordered by Pinka, Rába and Répce Rivers. The watercourses, especially alluvial ones, react very sensitively to tectonic forcing. However, the present-day course of the creeks and rivers are mostly regulated, therefore they are unsuitable for such studies. Consequently, the watercourses should be reconstructed from maps surveyed prior to the main water control measures. The Second Military Survey is a perfect source for such studies because it is the first survey has drawn in geodetic projection but the creeks haven't been regulated yet. The maps show intensive agricultural cultivation and silviculture in the study area. Especially grazing cultivation precincts of the streams is important for us. That phenomenon and data from other sources prove that the streams haven't been regulated in that time. The streams were able to meander, and flood its banks, and only natural levees are present. The general morphology south from the Kőszegi Mountains shows typical SSE slopes with low relief cut off by 30-60 meter high scarps followed by streams. That

    Full Text Available Introduction: The purpose of this study is to examine the relevance of non-specific safety belt use data for interventions to rural teens and to pilot a data collection project to provide more specific data to traffic safety stakeholders and educators in rural areas.Methods: Twelve high schools in Southeast Georgia were used for observed safety belt data collection over a 16 month period. Observational surveys were conducted at the entrance to student parking lots of the studied schools in the morning or afternoon. Observers were trained and survey methods were standardized to maintain comparability between results.Results: Observational surveys revealed a safety belt usage rate of 38.6% among high schools teens at the studied high schools. Safety belt usage rates ranged from 9.5% to 66.9%. Observed safety belt use for female vehicle occupants was 48.4% compared to 35.6% for males.Conclusion: The observational survey results from this study support research showing that rural teens have lower safety belt usage rates than adults or urban teens. Despite efforts to target rural areas, programs must specifically target sub populations, especially rural male teens, in order to hold any traction. Because of the wide gap between measured safety belt use in rural Georgia (79.9% and the studied rural high schools (38.6%, local program planners must assess actual safety belt usage in their high risk rural teen population in order to use accurate metrics for intervention and education efforts.

    Full Text Available This paper presents a comprehensive survey on transmission and distribution fault location algorithms that utilize synchronized measurements. Algorithms based on two-end synchronized measurements and fault location algorithms on three-terminal and multiterminal lines are reviewed. Series capacitors equipped with metal oxide varistors (MOVs, when set on a transmission line, create certain problems for line fault locators and, therefore, fault location on series-compensated lines is discussed. The paper reports the work carried out on adaptive fault location algorithms aiming at achieving better fault location accuracy. Work associated with fault location on power system networks, although limited, is also summarized. Additionally, the nonstandard high-frequency-related fault location techniques based on wavelet transform are discussed. Finally, the paper highlights the area for future research.

    Window opening behaviour has been shown to have a significant impact on airflow rates and hence energy consumption. Nevertheless, the inhabitant behaviour related to window opening in residential buildings is currently poorly investigated through both field surveys and building energy simulations....... In particular, reliable information regarding user behaviour in residential buildings is crucial for suitable prediction of building performance (energy consumption, indoor environmental quality, etc.). To face this issue, measurements of indoor climate and outdoor environmental parameters and window “opening...... and closing” actions were performed in 15 dwellings from January to August 2008 in Denmark. Probabilistic models of inhabitants’ window “opening and closing” behaviour were developed and implemented in the energy simulation software IDA ICE to improve window opening and closing strategies in simulations...

    2008-01-01

    Preventive interventions to reduce occupational injuries and health problems in farmers require the identification of factors that contribute to unsafe and health damaging behavior. This paper describes the development and validation of a self-report questionnaire, which measures the determinants of occupational health-related behaviors in farmers. A representative sample of 283 Flemish farmers completed a provisional 135 item questionnaire based on the Theory of Planned Behavior, measuring four behaviors related to occupational health (machinery use, animal handling, preventing falls, and pesticide use), as well as the intentions, attitudes, perceived social norms, and self-efficacy for each of these behaviors. The fit indices of the Confirmatory Factor Analysis turned out not to be sufficient to reproduce the dimensions of the TPB. Therefore exploratory factor analysis was use to determine the underlying dimensions. Principal Component Analyses (PCA) on the behavioral items yielded single component solutions explaining a considerable proportion of the variance for each behavior and for behavioral intentions. Principal component analyses toward an a priori three-component structure reflecting the TPB dimensions did not produce sufficient congruence for the determinants of the four behaviors. Subsequent Varimax rotations and discarding of redundant items resulted in three component solutions explaining 50% to 69% of the variance in the determinants of each behavior, corresponding with the dimensions of the TPB. Internal consistencies ranged from .25 to .89. Scale scores accounted for a significant proportion of the variance in intention and self-reported behavior. The study demonstrates the validity of the TPB in predicting behavior related to occupational safety and health in farmers, and provides a valid and reliable questionnaire to measure the cognitive concepts featured in this model. Both authors share the same view on this study's impact on industry. In

  18. Index of harm: a measure for comparing occupational risk across industries

    1979-01-01

    This areport explores the implications of an index-of-harm methodology that compares occupational risks among workers exposed to radiological and nonradiological harms. It extends the work of the International Commission on Radiological Protection (ICRP) by considering American rather than European and Japanese industry groups, by treating the relative importance of various occupational harms as a parameter rather than an arbitrary constant, and by identifying several ways in which both the methodology and the data base could be improved. Unfortunately, the data base is too fragmented, and radiological risk estimates are too imprecise for quantitative comparisons across industries. Inclusion of subjective risk preferences is one way to make policy-relevant judgments based on a limited data base. Our study agrees with known accidental fatality rates by showing the riskiest industries to be mining; agriculture, forestry, and fisheries; construction; transportation; and manufacturing - roughly in that order. Using a factor of five times the ICRP dose/risk parameter suggests that the index of harm for radiological workers exposed to 0.35 Rem/yr is still below that of the five riskiest industries. However, the rankings re altered considerably at the regulatory dose level of 5.0 Rem/yr. At that level, the nuclear industry would be significantly more risky, particularly when upper risk estimates are used. (PCS)

    There is currently no accepted standard denominator to calculate and to report the incidence of occupational exposures to bloodborne pathogens (OEBBPs) in health care. We performed a multicenter study of OEBBP injuries reported from 31 community hospitals in the southeastern United States from January 2003 to December 2006. A qualitative design was used to assess 4 commonly used denominators to calculate the incidence of OEBBP: patient-days; staffed beds; occupied beds and full-time employee equivalents (FTEs). Six criteria were used to assess the quality and suitability of each denominator as a standard method to calculate incidence of OEBBP. We also analyzed the correlation of hospital rankings produced by these 4 denominators. During 4 years of study, a total of 3375 occupational exposures were reported. Patient-days outperformed others as a denominator to calculate rates of OEBBP when judged by 6 predefined criteria. Data for staffed beds, occupied beds, and FTE were manually collected, infrequently reported, and often subject to missing data. Furthermore, FTE and staffed beds data also captured unoccupied beds and non-clinical employee data that were not associated with risk of OEBBP. Patient-days may be the most suitable and readily available denominator for standard reporting and benchmarking of incidence of OEBBP. Patient-days may be used as a standard method for comparing rates of OEBBP.

    PURPOSE. We conducted a systematic review examining the extent to which pediatric intervention research recently published in the American Journal of Occupational Therapy reflects occupational therapy’s holistic occupation-based tenets. METHOD. We surveyed 10 systematic reviews and analyzed 38 single effectiveness studies for intervention approach, type, level of environmental targeting, level of occupational task and participation practice, and measures used. RESULTS. Of the 38 single effectiveness studies, 12 (32%) explicitly incorporated both environmental targets of intervention and practice of complex or in vivo occupational tasks, with steady increases during the 2009–2013 time frame. CONCLUSION. In the area of children and youth, occupational therapy is making steady gains in reflecting and demonstrating the effectiveness of the profession’s holistic, occupation-based tenets. Occupational therapy researchers must be mindful to ensure that despite the reductionist nature of intervention research, interventions reflect the profession’s holistic understanding of the interplay between the child, environment, and occupations.

    In March 2012, the SAGE Working Group on Vaccine Hesitancy was convened to define the term "vaccine hesitancy", as well as to map the determinants of vaccine hesitancy and develop tools to measure and address the nature and scale of hesitancy in settings where it is becoming more evident. The definition of vaccine hesitancy and a matrix of determinants guided the development of a survey tool to assess the nature and scale of hesitancy issues. Additionally, vaccine hesitancy questions were piloted in the annual WHO-UNICEF joint reporting form, completed by National Immunization Managers globally. The objective of characterizing the nature and scale of vaccine hesitancy issues is to better inform the development of appropriate strategies and policies to address the concerns expressed, and to sustain confidence in vaccination. The Working Group developed a matrix of the determinants of vaccine hesitancy informed by a systematic review of peer reviewed and grey literature, and by the expertise of the working group. The matrix mapped the key factors influencing the decision to accept, delay or reject some or all vaccines under three categories: contextual, individual and group, and vaccine-specific. These categories framed the menu of survey questions presented in this paper to help diagnose and address vaccine hesitancy.

    Private higher education has become an important component of China's education system and is developing rapidly in recent years. There is a huge gap on the wages and welfare benefits, professional title appraisal and social status between private colleges and public colleges, resulting in increasingly prominent occupational stress of private college teachers, and severely affecting their physical and psychological health as well as the development of their colleges. Therefore, it is of great real-istic significance to survey and analyze the source and current situation of private college teachers' occupational stress. "Ques-tionnaire on Sources of College Teachers' Occupational Stress" by Shu Renlong[1] was adopted by this paper to measure the occupa-tional stress of private college teachers in Ji'nan City, and the re-sult shows that the overall stress of private college teachers has exceeded the moderate level, and the occupational stress of pro-fessional teachers is closely related to such sources as scientific research and evaluation, and besides, there are differences on different demographic variables.%民办高等教育现已成为我国教育体系中的重要组成部分,近年来发展迅速。民办高校教师在工资福利待遇、职称评定以及社会地位等方面与公办高校的教师存在较大差距,其职业压力也日益明显,严重影响其身心健康及所在高校的发展。因此,对民办高校教师的职业压力来源及现状进行调查分析,具有重要的现实意义。本研究采用束仁龙[1]的《高校教师职业压力来源问卷》对济南市民办高校教师进行职业压力测量,结果显示,民办高校教师总体压力已超过中等水平,专职教师的职业压力与科研、考核等压力源关联度较大,且在不同人口学变量上存在差异。

    Speech and language skills are an important developmental milestone for all children, and one of the most prevalent forms of developmental delay among Aboriginal children. However, population-based indicators of Aboriginal children's language outcomes are limited. Data from the Aboriginal Children's Survey (ACS) were used to examine measures of language for Aboriginal children who were 2 to 5 years of age. Responses to ACS questions on ability in any language were examined in exploratory factor analyses to determine possible language indicators. Construct validity was examined by regressing language outcomes onto socio-demographic characteristics known to be associated with children's language. Four language outcomes were identified and labelled: expressive language, mutual understanding, story-telling, and speech and language difficulties. The conceptualization of items from the ACS into separate language indicators can be used by researchers examining young Aboriginal children's language outcomes.

    Internationally, there is no consensus on how to best deal with admission requests in cases of full ICU bed occupancy. Knowledge about the degree of dissension and insight into the reasons for this dissension is lacking. Information about the opinion of ICU physicians can be used to improve decision-making regarding allocation of ICU resources. The aim of this study was to: Assess which factors play a role in the decision-making process regarding the admission of ICU patients; Assess the adherence to a Dutch guideline pertaining to rationing of ICU resources; Investigate factors influencing the adherence to this guideline. In March 2013, an online questionnaire was sent to all ICU physician members (n = 761, in 90 hospitals) of the Dutch Society for Intensive Care. 166 physicians (21.8 %) working in 64 different Dutch hospitals (71.1 %) completed the questionnaire. Factors associated with a patient's physical condition and quality of life were generally considered most important in admission decisions. Scenario-based adherence to the Dutch guideline "Admission request in case of full ICU bed occupancy" was found to be low (adherence rate 50.0 %). There were two main reasons for this poor compliance: unfamiliarity with the guideline and disagreement with the fundamental approach underlying the guideline. Dutch ICU physicians disagree about how to deal with admission requests in cases of full ICU bed occupancy. The results of this study contribute to the discussion about the fundamental principles regarding admission of ICU patients in case of full bed occupancy.

    Full Text Available Learning is the process of generating useful information from a huge volume of data. Learning can be either supervised learning (e.g. classification or unsupervised learning (e.g. Clustering Clustering is the process of grouping a set of physical objects into classes of similar object. Objects in real world consist of both numerical and categorical data. Categorical data are not analyzed as numerical data because of the absence of inherit ordering. This paper describes about ten different clustering algorithms, its methodology and the factors influencing its performance. Each algorithm is evaluated using real world datasets and its pro and cons are specified. The various similarity / dissimilarity measure applied to categorical data and its performance is also discussed. The time complexity defines the amount of time taken by an algorithm to perform the elementary operation. The time complexity of various algorithms are discussed and its performance on real world data such as mushroom, zoo, soya bean, cancer, vote, car and iris are measured. In this survey Cluster Accuracy and Error rate for four different clustering algorithm (K-modes, fuzzy K-modes, ROCK and Squeezer, two different similarity measure (DISC and Overlap and DILCA applied for hierarchy and partition algorithm are evaluated.

    Full Text Available Association rule mining has long being plagued with the problem of finding meaningful, actionable knowledge from the large set of rules. In this age of data deluge with modern computing capabilities, we gather, distribute, and store information in vast amounts from diverse data sources. With such data profusion, the core knowledge discovery problem becomes efficient data retrieval rather than simply finding heaps of information. The most common approach is to employ measures of rule interestingness to filter the results of the association rule generation process. However, study of literature suggests that interestingness is difficult to define quantitatively and can be best summarized as, a record or pattern is interesting if it suggests a change in an established model. Almost twenty years ago, Gregory Piatetsky-Shapiro and Christopher J. Matheus, in their paper, “The Interestingness of Deviations,” argued that deviations should be grouped together in a finding and that the interestingness of a finding is the estimated benefit from a possible action connected to it. Since then, this field has progressed and new data mining techniques have been introduced to address the subjective, objective, and semantic interestingness measures. In this brief survey, we review the current state of literature around interestingness of deviations, i.e. outliers with specific interest around probabilistic measures using Bayesian belief networks.

    Full Text Available Background: Cardiovascular disease (CVD is the main mortality cause worldwide. Noise and vibration are considered to be occupational risk factors, but little is known about their cardiovascular effects in Bulgaria in terms of gender and various professional groups. The aim of this study has been to investigate the risk of prevalent CVD, associated with occupational noise and vibration exposure. Material and Methods: We conducted a secondary analysis of the data from 3 waves of the European Working Conditions Survey (EWCS 2001–2010 – a nationally-representative cross-sectional questionnaire survey covering 3149 workers aged ≥ 15 years in Bulgaria. Data on self-reported heart disease were linked to self-reported occupational noise and vibration, adjusting for other factors. Results from the 3 waves were pooled together using the inverse variance heterogeneity (IVhet meta-analysis. Results: For noise, the risk was elevated among women (relative risk (RR = 1.26, 95% confidence interval (CI: 0.53–3.01, but not men (RR = 0.49, 95% CI: 0.14–1.65. Long-term workers had RR = 1.01, 95% CI: 0.60–1.69. For vibration, the risk was increased in all participants. It was higher among men (RR = 2.56, 95% CI: 1.60–4.09 than it was among women (RR = 1.32, 95% CI: 0.77–2.27. Among long-term, industrial, and service workers it was RR = 1.56, 95% CI: 1.02–2.40; RR = 1.10, 95% CI: 0.61–1.98, and RR = 1.18, 95% CI: 0.57–2.46, respectively. Conclusions: Occupational vibration was a risk factor for prevalent heart disease in Bulgaria. Noise was an alleged risk factor only among long-term workers and women. Med Pr 2016;67(4:435–445

    A study was conducted to test whether patient reports of medical errors via surveys could produce sufficiently accurate information to be used as a measure of patient safety. A survey mailed regularly by a large multispecialty medical group to recent patients to assess their satisfaction and error experiences was expanded to collect more details about the patient-perceived errors. Following an initial mailing to 3,109 patients and parents of child patients soon after they had office visits in June 2005, usable mailed or phone follow-up responses were obtained from 1,998 respondents (65.1% adjusted). Responses were reviewed through a two-stage process that included chart audits and implicit physician reviewer judgments. The analysis categorized the review results and compared patient-reported errors with satisfaction. Of the 1,998 respondents, 219 (11.0%) reported 247 separate incidents, for a rate of 12.4 errors per 100 patients. After complete review, only 5 (2.0%) of these incidents were judged to be real clinician errors. Most appeared to represent misunderstandings or behavior/communication problems, but 15.4% lacked sufficient information to categorize. Women, Hispanics, and those aged 41-60 years were most likely to report errors. Those respondents making error reports were much more likely to report visit dissatisfaction than those not reporting them (odds ratio [OR] = 13.8, p technical medical errors and patient safety reliably without added evaluation. This study's findings need to be replicated elsewhere before generalizing from one metropolitan region and a patient population that is about two-thirds members of one health plan.

    The nickel concentration in fingernails from 2 groups of people occupationally exposed to nickel was determined. In one group, comprising 83 persons moderately exposed to nickel, the mean +/- standard deviation (SD) was 29.2 micrograms/g +/- 56.7 micrograms/g and the median 13.8 micrograms/g (range...... 0.926-396 micrograms/g). In the other group, comprising 51 persons heavily exposed to nickel, the mean +/- SD was 123 micrograms/g +/- 289 micrograms/g and the median 29.9 micrograms/g (range 1.95-1770 micrograms/g). Both levels were significantly different from the normal nickel concentration...... in nails (p less than 0.001). The difference between the 2 levels was also significant (p less than 0.001). No correlation between the nickel concentration in fingernails and the duration of exposure could be demonstrated.

    The municipality of Egedal decided in 2006 to make use of the possibility in the Danish Planning Law for a municipality to tighten the energy requirements in the local plan for a new settlement to be erected in the municipality. During the years 2007-2011 a total of 442 dwellings were to be designed and constructed with a heating demand corresponding to the Danish low-energy standard referred to as ''low-energy class 1'' in a new settlement called Stenloese Syd. This means that the energy consumption is to be 50% lower than the requirement in BR08 (Danish Building Regulations 2008). 66 flats were to be designed and constructed with a yearly heating demand of 15 kWh/m{sup .} Furthermore, the Concerto community include a kindergarten and an activity centre for elderly people. All the single family houses were to be heated by a heat pump supported by a 3 m{sup }thermal solar system for hot water preparation. The dense low-rise housing are to be heated by a district heating network. All dwellings were to be equipped with a mechanical ventilation system with heat recovery and an electronic system for energy monitoring and control of the heating systems. The first houses were occupied in 2008. This report presents part of the results of an evaluation of the project that was performed in the settlement. The evaluation consisted of a questionnaire survey of occupant experiences and satisfaction in 35 single-family houses, measurements of energy consumption in 22 selected single-family houses and 58 flats, and measurements, assessments, and a series of physical measurements of selected indoor climate parameters in 7 selected single-family houses during March 2012.

    Understanding quality of life and participation is a key aspect of occupational therapy research. The use of smartphones to deliver experience-sampling surveys may provide an accessible way to monitor these outcomes. This study used smartphone-based experience sampling methods (ESM) to investigate factors influencing momentary quality of life (mQOL) of university students. A convenience sample of students at an Australian university participated. Using a custom smartphone application, ESM surveys were sent six to eight times, every second day, over a week. Participants indicated their mQOL, occupational participation, occupational enjoyment, social context and location via surveys and provided demographic and health information in a single self-report questionnaire. The relationship between mQOL and variables was analysed at the survey level using logistic regression. Forty students completed 391 surveys. Higher mQOL was significantly related to participation in productive occupations (z = 3.48; P = 0.001), moderate (z = 4.00; P sample, analysing at the individual level, and using ESM in conjunction with other methodologies is recommended. © 2017 Occupational Therapy Australia.

    We surveyed carbon fiber reinforced plastic orthoses (carbon orthoses) and their associated occupational and medical problems based on a questionnaire sent to 310 companies which were members of the Japan Orthotics and Prosthetics Association. Of all the companies, 232 responded: 77 of the 232 companies dealt with ready-made carbon orthoses, 52 dealt with fabricated custom-made orthoses, and 155 did not dealt with carbon orthoses. Although the total number of custom-made carbon ortheses in Japan was 829/ 5 years, there was a difference by region, and one company fabricated only 12 (per 5 years) custom-made carbon orthoses on average. The advantages of the carbon orthosis were the fact that it was "light weight", "well-fitted", had a "good appearance", and "excellent durability", while the disadvantages were that it was "expensive", "high cost of production", of "black color", and required a "longer time for completion", and "higher fabrication techniques". From the standpoint of industrial medicine, "scattering of fine fragments of carbon fibers", "itching on the skin" and "health hazards" were indicated in companies that manufacture the orthosis. In order to make the carbon orthosis more popular, it is necessary to develop a new carbon material that is easier to fabricate at a lower cost, to improve the fabrication technique, and to resolve the occupational and medical problems.

  1. Measuring coverage in MNCH: total survey error and the interpretation of intervention coverage estimates from household surveys.

    Directory of Open Access Journals (Sweden)

    Thomas P Eisele

    Full Text Available Nationally representative household surveys are increasingly relied upon to measure maternal, newborn, and child health (MNCH intervention coverage at the population level in low- and middle-income countries. Surveys are the best tool we have for this purpose and are central to national and global decision making. However, all survey point estimates have a certain level of error (total survey error comprising sampling and non-sampling error, both of which must be considered when interpreting survey results for decision making. In this review, we discuss the importance of considering these errors when interpreting MNCH intervention coverage estimates derived from household surveys, using relevant examples from national surveys to provide context. Sampling error is usually thought of as the precision of a point estimate and is represented by 95% confidence intervals, which are measurable. Confidence intervals can inform judgments about whether estimated parameters are likely to be different from the real value of a parameter. We recommend, therefore, that confidence intervals for key coverage indicators should always be provided in survey reports. By contrast, the direction and magnitude of non-sampling error is almost always unmeasurable, and therefore unknown. Information error and bias are the most common sources of non-sampling error in household survey estimates and we recommend that they should always be carefully considered when interpreting MNCH intervention coverage based on survey data. Overall, we recommend that future research on measuring MNCH intervention coverage should focus on refining and improving survey-based coverage estimates to develop a better understanding of how results should be interpreted and used.

    Full Text Available Introduction In order to discharge the patients receiving treatment with large radiation doses of 131I for thyroid cancer, it is necessary to measure and evaluate the external dose rates of these patients. The aim of the study was to assess a new method of external dose rate measurement, and to analyze the obtained results as a function of time. Materials and Methods In this study, a telescopic radiation survey meter was utilized to measure the external dose rates of a sample population of 192 patients receiving treatment with high-dose 131I at one, 24, and 48 hours after dose administration. Results The proposed technique could reduce the occupational radiation exposure of the physicist by a factor of 1/16. Moreover, the external dose rates of both genders rapidly decreased with time according to bi-exponential equations, which could be attributed to the additional factors associated with iodine excretion, as well as the physiology of the body in terms of 131I uptake. Conclusion According to the results of this study, telescopic radiation survey meter could be used to measure the external dose rates of patients receiving treatment with 131I. Furthermore, the average difference in the radiation exposure between female and male patients was calculated to be less than 17%.

    The purpose of this article is to analyze the results of a 10-year survey of the radiation effects of some immune parameters of occupationally exposed personnel from the Nuclear Power Plant "Kozloduy", Bulgaria. 438 persons working in NPP with cumulative doses between 0.06 mSv and 766.36mSv and a control group with 65 persons were studied. Flow cytometry measurements of T, B, natural killer (NK) and natural killer T (NKT) cell lymphocyte populations were performed. Data were interpreted with regard to cumulative doses, length of service and age. The average values of the studied parameters of cellular immunity were in the reference range relative to age and for most of the workers were not significantly different from the control values. Low doses of ionizing radiation showed some trends of change in the number of CD3+CD4+ helper-inducer lymphocytes, CD3+ CD8+ and NKT cell counts. The observed changes in some of the studied parameters could be interpreted in terms of adaptation processes at low doses. At doses above 100-200 mSv, compensatory mechanisms might be involved to balance deviations in lymphocyte subsets. The observed variations in some cases could not be attributed only to the radiation exposure because of the impact of a number of other exogenous and endogenous factors on the immune system.

    The purpose of this study was to examine the support activities provided for occupational health nurses aimed at improving psychosocial working environments, related knowledge and skills, and learning environments as well as associations among these factors. In addition, we aimed to create correlated factor models to describe the support activities in order to identify ways to promote these activities among occupational health nurses. An anonymous mail-based questionnaire survey was conducted of occupational health nurses who were members of the Japan Society for Occupational Health and belonged to enterprises or independent health insurance societies. Among 356 returned questionnaires (response rate: 46.4%), all the main items were answered in 329 (valid response rate: 92.4%), and these questionnaires were analyzed. Factor analysis was performed for the seven items pertaining to support activities for the improvement of psychosocial working environments and models of each factor of the support activities were developed using covariance structure analysis. In the factor analysis, [Clarifying a stress-related situation and providing advice] and [Facilitating workplace involvement] were identified as support-related factors. The mean implementation rates for these approaches were approximately 50 to 80%, and less than 40%, respectively. [Clarifying a stress-related situation and providing advice] was associated with skills of "providing superiors with explanations to enhance their understanding" and "collecting and analyzing stress survey results by department", and knowledge of "personal stress questionnaires" and "common stress factors in working environments". The above-mentioned knowledge and skills were associated with self-learning of "examining and reporting daily activities for the improvement of working environments" and "reviewing related papers". [Facilitating workplace involvement] was associated with skills of "indirectly supporting discussions led by

    We examined the current status of specialized agencies for occupational health management (SAs) and their workforce. Furthermore, we aimed to clarify the current practice status of SA healthcare professionals and factors that influence their performance. To examine the current SA workforce, we analyzed data from the 2014 Survey of Current Status of SA and their Workforce from the Ministry of Employment and Labor (MOEL). Furthermore, we mailed out an original questionnaire to SA professionals to determine their current health management status and factors that affect their performance. Data from the respondents (N = 384) were analyzed. In 2014, the workforce performing health management in SAs comprised 232 physicians, 507 nurses, and 312 occupational hygienists, with no significant regional differences in the distribution of physicians and nurses. According to the findings of the questionnaire, the average daily number of worker consultations by physicians and nurses was 22.8, while the average time taken for health management ranged from 74.3 to 104.3 min, depending on the size of the firm. Most of the respondents (41.5%) answered that they were following-up on more than 80% of individuals with illnesses. Among health management tasks, performance scores of "consultations for general diseases" and "consultations for lifestyle habits" were relatively high, whereas health promotion activities at workplaces were relatively low. There was a significant correlation between the utilization of general and special health examination results and task performance. Among health management tasks, follow-up management of individuals with illnesses and consultations for disease/lifestyle habits were relatively well performed, whereas health promotion activities at workplaces were not performed well. Among factors that positively influenced SA performance at workplaces, only the utilization of health examination results had significant effects. Therefore, to accomplish

    Full Text Available Occupational exposure to cytotoxic drugs is a global concern. We conducted this cross-sectional study in 2012 to describe the adverse effects experienced by nurses working in one of chemotherapy facilities affiliated to Shiraz University of Medical Sciences, Shiraz, southern Iran, and their proper use of personal protective equipment and educational programs. The frequency of side effects reported by participants was noticeably high. Approximately, 60% of the nurses used all personal protective equipment. There were air conditioner ventilation systems in all facilities, but they were not standard. Clinics did not have any dedicated room. Lack of adequate training was noticeable among all participants. We concluded that establishment of safety regulations, health care workers safety surveillance systems as well as continuous training for nurses are of paramount importance.

  10. Post-occupancy evaluation and field studies of thermal comfort

    2005-08-01

    The similarities and differences are explored in both the aims and the methods between post-occupancy evaluations and field studies of thermal comfort in buildings. The interpretations of the field study results are explored, especially the ways the results differ from laboratory experiments. Particular attention is drawn to the dynamic nature of the interaction between buildings and their occupants. Answers to questions of the type used in post-occupancy evaluations are compared with results from field studies of thermal comfort, and the implications of these findings for the evaluation of buildings and the conduct of post-occupancy evaluation are explored. Field studies of thermal comfort have shown that the way in which occupants evaluate the indoor thermal environment is context-dependent and varies with time. In using occupants as part of the means of measuring buildings, post-occupancy evaluations should be understood as reflecting the changing nature of the relationship between people, the climate and buildings. Surveys are therefore measuring a moving target, and close comparison based on such surveys need to take this in to account. (author)

  12. Measurement of thermal conductivity and diffusivity in situ: Literature survey and theoretical modelling of measurements

    In situ measurements of thermal conductivity and diffusivity of bedrock were investigated with the aid of a literature survey and theoretical simulations of a measurement system. According to the surveyed literature, in situ methods can be divided into `active` drill hole methods, and `passive` indirect methods utilizing other drill hole measurements together with cutting samples and petrophysical relationships. The most common active drill hole method is a cylindrical heat producing probe whose temperature is registered as a function of time. The temperature response can be calculated and interpreted with the aid of analytical solutions of the cylindrical heat conduction equation, particularly the solution for an infinite perfectly conducting cylindrical probe in a homogeneous medium, and the solution for a line source of heat in a medium. Using both forward and inverse modellings, a theoretical measurement system was analysed with an aim at finding the basic parameters for construction of a practical measurement system. The results indicate that thermal conductivity can be relatively well estimated with borehole measurements, whereas thermal diffusivity is much more sensitive to various disturbing factors, such as thermal contact resistance and variations in probe parameters. In addition, the three-dimensional conduction effects were investigated to find out the magnitude of axial `leak` of heat in long-duration experiments. The radius of influence of a drill hole measurement is mainly dependent on the duration of the experiment. Assuming typical conductivity and diffusivity values of crystalline rocks, the measurement yields information within less than a metre from the drill hole, when the experiment lasts about 24 hours. We propose the following factors to be taken as basic parameters in the construction of a practical measurement system: the probe length 1.5-2 m, heating power 5-20 Wm{sup -1}, temperature recording with 5-7 sensors placed along the probe, and

  13. Analysis of occupational accidents: prevention through the use of additional technical safety measures for machinery.

    2016-01-01

    This article presents an analysis of results of 1035 serious and 341 minor accidents recorded by Poland's National Labour Inspectorate (PIP) in 2005-2011, in view of their prevention by means of additional safety measures applied by machinery users. Since the analysis aimed at formulating principles for the application of technical safety measures, the analysed accidents should bear additional attributes: the type of machine operation, technical safety measures and the type of events causing injuries. The analysis proved that the executed tasks and injury-causing events were closely connected and there was a relation between casualty events and technical safety measures. In the case of tasks consisting of manual feeding and collecting materials, the injuries usually occur because of the rotating motion of tools or crushing due to a closing motion. Numerous accidents also happened in the course of supporting actions, like removing pollutants, correcting material position, cleaning, etc.

    The imprint of baryon acoustic oscillations (BAO) in large-scale structure can be used as a standard ruler for mapping out the cosmic expansion history, and hence for testing cosmological models. In this article we briefly describe the scientific background to the BAO technique, and forecast the potential of the Phase 1 and 2 SKA telescopes to perform BAO surveys using both galaxy catalogues and intensity mapping, assessing their competitiveness with current and future optical galaxy surveys. We find that a 25,000 sq. deg. intensity mapping survey on a Phase 1 array will preferentially constrain the radial BAO, providing a highly competitive 2% constraint on the expansion rate at z ~ 2. A 30,000 sq. deg. galaxy redshift survey on SKA2 will outperform all other planned experiments for z < 1.4.

    The study of the regulation of occupations has a long and distinguished tradition in economics. In this paper, I present the central arguments and unresolved issues involving the costs and benefits of occupational licensing. The main benefits that are suggested for occupational licensing involve improving quality for those persons receiving the service. In contrast, the costs attributed to this labor market institution are that it restricts the supply of labor to the occupation and thereby dr...

    2015-09-01

    Technical literature provides numerous studies concerning radiofrequency exposure measurements for various radio communication devices, but there are few studies related to exposure of personnel operating military radio equipment. In order to evaluate exposure and identify cases when safety requirements are not entirely met, both measurements and simulations are needed for accurate results. Moreover, given the technical characteristics of the radio devices used in the military, personnel mainly operate in the near-field region so both measurements and simulation becomes more complex. Measurements were made in situ using a broadband personal exposimeter equipped with two isotropic probes for both electric and magnetic components of the field. The experiment was designed for three different operating frequencies of the same radio equipment, while simulations were made in FEKO software using hybrid numerical methods to solve complex electromagnetic field problems. The paper aims to discuss the comparative results of the measurements and simulation, as well as comparing them to reference levels specified in military or civilian radiofrequency exposure standards.

    We present a study of the clustering and halo occupation distribution of Baryon Oscillation Spectroscopic Survey (BOSS) CMASS galaxies in the redshift range 0.43 veto masks and fibre collisions are included in the model, which reproduces within 1σ errors the observed monopole of the two-point correlation function at all relevant scales: from the smallest scales, 0.5 h-1 Mpc, up to scales beyond the baryon acoustic oscillation feature. This model also agrees remarkably well with the BOSS galaxy power spectrum (up to k ˜ 1 h Mpc-1), and the three-point correlation function. The quadrupole of the correlation function presents some tensions with observations. We discuss possible causes that can explain this disagreement, including target selection effects. Overall, the standard HAM model describes remarkably well the clustering statistics of the CMASS sample. We compare the stellar-to-halo mass relation for the CMASS sample measured using weak lensing in the Canada-France-Hawaii Telescope Stripe 82 Survey with the prediction of our clustering model, and find a good agreement within 1σ. The BigMD-BOSS light cone including properties of BOSS galaxies and halo properties is made publicly available.

    2015-01-01

    High-performance liquid chromatography/mass spectrometry (HPLC/MS) is sensitive and specific for targeted quantitative analysis and is readily utilized for small molecules from biological matricies. This brief review describes recent selected HPLC/MS methods for the determination of urinary mercapturic acids (mercapturates) which are useful as biomarkers in characterizing human exposure to electrophilic industrial chemicals in occupational and environmental studies. Electrophilic compounds owing to their reactivity are used in chemical and industrial processes. They are present in industrial emissions, are combustion products of fossil fuels, and are components in tobacco smoke. Their presence in both the industrial and general environment are of concern for human and environmental health. Urinary mercapturates which are the products of metabolic detoxification of reactive chemicals provide a non-invasive tool to investigate human exposure to electrophilic toxicants. Selected recent mercapturate quantification methods are summarized and specific cases are presented. The biological formation of mercapturates is introduced and their use as biomarkers of metabolic processing of electrophilic compounds is discussed. Also, the use of liquid chromatography/tandem mass spectrometry in simultaneous determinations of the mercapturates of multiple parent compounds in a single determination is considered, as well as future trends and limitations in this area of research.

    Popesso, P; Böhringer, Hans; Romaniello, M

    2006-01-01

    We explore the mass-to-light ratio in galaxy clusters and its relation to the cluster mass. We study the relations among the optical luminosity ($L_{op}$), the cluster mass ($M_{200}$) and the number of cluster galaxies within $r_{200}$ ($N_{gal}$) in a sample of 217 galaxy clusters with confirmed 3D overdensity. We correct for projection effects, by determining the galaxy surface number density profile in our cluster sample. This is best fitted by a cored King profile in low and intermediate mass systems. The core radius decreases with cluster mass, and, for the highest mass clusters, the profile is better represented by a generalized King profile or a cuspy Navarro, Frenk & White profile. We find a very tight proportionality between $L_{op}$ and $N_{gal}$, which, in turn, links the cluster mass-to-light ratio to the Halo Occupation Distribution $N_{gal}$ vs. $M_{200}$. After correcting for projection effects, the slope of the $L_{op}-M_{200}$ and $N_{gal}-M_{200}$ relations is found to be $0.92\\pm0.03$,...

    2017-02-20

    This paper has two objectives: (1) presenting recent advances in personality theory whereby personality traits are conceptualized within a framework that focuses on the dynamic interactions of behaviour, biology, context, and states, and (2) discussing the implications of these developments for measurement and medical selection. We start by presenting evidence that traits are no longer regarded as stable deterministic predictors of behaviour. Instead, traits are found to change across generations, the life span, and in response to environmental contingencies. Thus, there is an urgent need to explore how traits change as function of medical education. Second, drawing on recent theory and research (behavioural reaction norms and the density distribution model) we highlight evidence to show how the expression of trait relevant behaviour is dependent on context, and is distributed with an average (typical behaviour or personality) and a variance (plasticity or adaptability), with traditional personality measure associated with typical responding. Third, we demystify that some traits are better than others showing that so-called "good" traits have a dark-side. Fourth, we show how these developments impact on how personality might be assessed, thereby presenting recent evidence on the use of contextualized personality measures, situational judgment tests, other reports, and implicit measures. Throughout the paper, we outline the key implications of these developments for medical selection practices.

    Burnout represents a critical disruption in an individual's relationship with work, resulting in a state of exhaustion in which one's occupational value and capacity to perform are questioned. Burnout can negatively affect an individual's personal life, as well as employers in terms of decreased work quality, patient/client satisfaction, and employee retention. Occupational stress is a known contributor to burnout and occurs as a result of employment requirements and factors intrinsic to the work environment. Empirical research examining genetic counselor-specific burnout is limited; however, existing data suggests that genetic counselors are at increased risk for burnout. To investigate the relationship between occupational stress and burnout in genetic counselors, we administered an online survey to members of three genetic counselor professional organizations. Validated measures included the Maslach Burnout Inventory-General Survey (an instrument measuring burnout on three subscales: exhaustion, cynicism, and professional efficacy) and the Occupational Stress Inventory-Revised (an instrument measuring occupational stress on 14 subscales). Of the 353 respondents, more than 40 % had either considered leaving or left their job role due to burnout. Multiple regression analysis yielded significant predictors for burnout risk. The identified sets of predictors account for approximately 59 % of the variance in exhaustion, 58 % of the variance in cynicism, and 43 % of the variance in professional efficacy. Our data confirm that a significant number of genetic counselors experience burnout and that burnout is correlated with specific aspects of occupational stress. Based on these findings, practice and research recommendations are presented.

    Full Text Available Abstract Background Much of the unskilled and semi-skilled workforce in Thailand comprises migrant workers from neighbouring countries. While, in principle, healthcare facilities in the host country are open to those migrants registered with the Ministry of Labour, their actual healthcare-seeking preferences and practices, as well as those of unregistered migrants, are not well documented. This study aimed to describe the patterns of healthcare-seeking behaviours of immigrant workers in Thailand, emphasizing healthcare practices for TB-suspicious symptoms, and to identify the role of occupation and other factors influencing these behaviours. Methods A survey was conducted among 614 immigrant factory workers (FW, rubber tappers (RT and construction workers (CW, in which information was sought on socio-demography, history of illness and related healthcare-seeking behaviour. Mixed effects logistic regression modeling was employed in data analysis. Results Among all three occupations, self-medication was the most common way of dealing with illnesses, including the development of TB-suspicious symptoms, for which inappropriate drugs were used. Only for GI symptoms and obstetric problems did migrant workers commonly seek healthcare at modern healthcare facilities. For GI illness, FW preferred to attend the in-factory clinic and RT a private facility over government facilities owing to the quicker service and greater convenience. For RT, who were generally wealthier, the higher cost of private treatment was not a deterrent. CW preferentially chose a government healthcare facility for their GI problems. For obstetric problems, including delivery, government facilities were utilized by RT and CW, but most FW returned to their home country. After adjusting for confounding, having legal status in the country was associated with overall greater use of government facilities and being female and being married with use of both types of modern healthcare

    Describe the clinical use of virtual reality (VR)/active videogaming (AVG) by physical therapists (PTs) and occupational therapists (OTs) in Canada, identify usage barriers and facilitators, evaluate factors that predict intention to use VR/AVGs, and determine therapists' learning needs. Cross-sectional survey. Online survey of therapists in Canada who were members of 1 of 26 professional PT or OT colleges or associations using the Assessing Determinants Of Prospective Take-up of Virtual Reality (ADOPT-VR2) Instrument. We received 1071 (506 PTs, 562 OTs, 3 dual-trained) responses. Forty-six percent had clinical VR/AVG experience; only 12% reported current use, with the Wii being the most clinically accessible (41%) system. Therapists used VR/AVGs primarily in rehabilitation (32%) and hospital (29%) settings, preferentially targeting balance (39.3%) and physical activity (19.8%) outcomes. Stroke (25.8%), brain injury (15.3%), musculoskeletal (14.9%), and cerebral palsy (10.5%) populations were most frequently treated. Therapists with VR/AVG experience rated all ADOPT-VR2 constructs more highly than did those without experience (P < 0.001). Factors predictive of intention to use VR included the technology's perceived usefulness and therapist self-efficacy in VR/AVG use (P < 0.001). Highest-rated barriers to VR/AVG use were lack of funds, space, time, support staff, and appropriate clients, whereas facilitators included client motivation, therapist knowledge, and management support. Most (76%) respondents were interested in learning more. Understanding use, predictors of use, and learning needs is essential for developing knowledge translation initiatives to support clinical integration of VR/AVGs. Results of this first national survey will inform the creation of resources to support therapists in this field.

    Accurate statistical measurement with large imaging surveys has traditionally required throwing away a sizable fraction of the data. This is because most measurements have have relied on selecting nearly complete samples, where variations in the composition of the galaxy population with seeing, depth, or other survey characteristics are small. We introduce a new measurement method that aims to minimize this wastage, allowing precision measurement for any class of stars or galaxies detectable in an imaging survey. We have implemented our proposal in Balrog, a software package which embeds fake objects in real imaging in order to accurately characterize measurement biases. We demonstrate this technique with an angular clustering measurement using Dark Energy Survey (DES) data. We first show that recovery of our injected galaxies depends on a wide variety of survey characteristics in the same way as the real data. We then construct a flux-limited sample of the faintest galaxies in DES, chosen specifically for th...

    We present the 2-degree Field Lensing Survey (2dFLenS), a new galaxy redshift survey performed at the Anglo-Australian Telescope. 2dFLenS is the first wide-area spectroscopic survey specifically targeting the area mapped by deep-imaging gravitational lensing fields, in this case the Kilo-Degree Survey. 2dFLenS obtained 70,079 redshifts in the range z < 0.9 over an area of 731 sq deg, and is designed to extend the datasets available for testing gravitational physics and promote the development of relevant algorithms for joint imaging and spectroscopic analysis. The redshift sample consists first of 40,531 Luminous Red Galaxies (LRGs), which enable analyses of galaxy-galaxy lensing, redshift-space distortion, and the overlapping source redshift distribution by cross-correlation. An additional 28,269 redshifts form a magnitude-limited (r < 19.5) nearly-complete sub-sample, allowing direct source classification and photometric-redshift calibration. In this paper, we describe the motivation, target selection...

  15. Alternative Magnetic Field Exposure Metrics: Occupational Measurements in Trolley Workers (invited paper)

    Energy Technology Data Exchange (ETDEWEB)

    Yost, M

    1999-07-01

    Epidemiological studies on extremely low frequency (ELF) magnetic fields have widely used personal or area sampling to evaluate exposures based on the time-weighted averaged flux density magnitude (TWA field). Relatively few studies have evaluated 'alternative' exposure metrics related to field characteristics such as temporal variability, frequency harmonics, vector polarisation, spatial orientation, static fields, high frequency transients, or induced electric fields. These field attributes fall into three major categories: (1) temporal characteristics of exposure intensity and timing, (2) frequency-domain characteristics, (3) spatial characteristics. The first category describes the magnitude and time history of exposure, including the TWA field metric, which most often is the focus of MF exposure assessment. The second category depicts the waveform characteristic (harmonic content), which has been relatively poorly described in most studies. The third category describes the field vector's time-space orientation and relation to static fields. Some examples of 'alternative metrics' that have been proposed based on biological mechanisms and potential measurement techniques are examined. The limited correlation of some alternative metrics with the TWA field metric in available data suggests that substantial exposure misclassification could occur if measurement protocols only focus on average field levels.

  16. Validity of temporal measures as proxies for measuring acculturation in Asian Indian survey respondents.

    Science.gov (United States)

    Bharmal, Nazleen; Hays, Ron D; McCarthy, William J

    2014-10-01

    There are few validated acculturation measures for Asian Indians in the U.S. We used the 2004 California Asian Indian Tobacco Survey to examine the relationship between temporal measures and eleven self-reported measures of acculturation. These items were combined to form an acculturation scale. We performed psychometric analysis of scale properties. Greater duration of residence in the U.S., greater percentage of lifetime in the U.S., and younger age at immigration were associated with more acculturated responses to the items for Asian Indians. Item-scale correlations for the 11-item acculturation scale ranged from 0.28-0.55 and internal consistency reliability was 0.73. Some support was found for a two-factor solution; one factor corresponding to cultural activities (α = 0.70) and the other to social behaviors (α = 0.59). Temporal measures only partially capture the full dimensions of acculturation. Our scale captured several domains and possibly two dimensions of acculturation.

  20. Occupational Consciousness.

    Science.gov (United States)

    Ramugondo, Elelwani L

    2015-10-02

    Occupational consciousness refers to ongoing awareness of the dynamics of hegemony and recognition that dominant practices are sustained through what people do every day, with implications for personal and collective health. The emergence of the construct in post-apartheid South Africa signifies the country's ongoing struggle with negotiating long-standing dynamics of power that were laid down during colonialism, and maintained under black majority rule. Consciousness, a key component of the new terminology, is framed from post-colonial perspectives - notably work by Biko and Fanon - and grounded in the philosophy of liberation, in order to draw attention to continuing unequal intersubjective relations that play out through human occupation. The paper also draws important links between occupational consciousness and other related constructs, namely occupational possibilities, occupational choice, occupational apartheid, and collective occupation. The use of the term 'consciousness' in sociology, with related or different meanings, is also explored. Occupational consciousness is then advanced as a critical notion that frames everyday doing as a potentially liberating response to oppressive social structures. This paper advances theorizing as a scholarly practice in occupational science, and could potentially expand inter or transdisciplinary work for critical conceptualizations of human occupation.

    Oliveira, Paulo Antonio Barros; Mendes, Jussara Maria Rosa

    2014-12-01

    This article presents the report of a survey on health surveillance activities performed in poultry processing plants in the south of Brazil. It aims to contribute to an understanding of the work process developed, the growth of the sector, the organization of labor and the confrontation with the economic model of this sector, which has been exposing employees to working conditions that undermine their health. The working conditions identified are considered largely incompatible with health and human dignity. The study supports interinstitutional intervention, especially with the Public Ministry of Labor, criticizes the weak implementation of specific government interventions in health conditions in the industry and introduces the new Regulatory Standard 36 as a positive perspective for the near future.

    2003-01-01

    To analyse the relationship between social class based on occupation and level of education in the study of social inequalities in health and use of health services. DESSIGN: Cross-sectional study (health interview survey). General population of the city of Cornellà de Llobregat (Spain). Representative sample of subjects aged 14 years old or over (1043 men and 1101 women) who personally answered the questionnaire. We analyse the association between social class and level of studies and different independent variables (self-perceived health, smoking, medical visits) by means of logistic regression. The proportion of men who declare their self-perceived health as poor is higher among those who have low education (45.4%) than among those who have primary education level or higher (25.9%). The prevalence of smoking shows a similar pattern (54.2% versus 41.5%), with a gradient effect, which is statistically non-significant. However, these differences are no longer evident if social class is used to group the individuals. No clear association is observed between the use of health services and socio economic level. We need to use several indicators of socioeconomic position to evaluate social inequalities In this disadvantaged population, level of education seems to be a good indicator to study social inequalities in health.

  10. Measuring primordial non-Gaussianity with weak-lensing surveys

    CERN Document Server

    Hilbert, Stefan; Smith, Robert E; Desjacques, Vincent

    2012-01-01

    We study the ability of future weak lensing (WL) surveys to constrain primordial non-Gaussianity of the local type. We use a large ensemble of simulated WL maps with survey specifications relevant to Euclid and LSST. The simulations assume Cold Dark Matter cosmologies that vary certain parameters around fiducial values: the non-Gaussianity parameter f_NL, the matter density parameter Omega_m, the amplitude of the matter power spectrum sigma_8, the spectral index of the primordial power spectrum n_s, and the dark-energy equation-of-state parameter w_0. We assess the sensitivity of the cosmic shear correlation functions, the third-order aperture mass statistics, and the abundance of shear peaks to these parameters. We find that each of the considered probes provides unmarginalized constraints of Delta f_NL ~ 20 on f_NL. Marginalized constraints from any individual WL probe are much weaker due to strong correlations between parameters. However, the parameter errors can be substantially reduced by combining infor...

    HOLDEN, N.E.

    2005-08-13

    Along with my usual weekly review of the published literature for new nuclear data, I also search for new candidates for best measurements of isotopic abundances from a single source. Most of the published articles, that I previously had found in the Research Library at the Brookhaven Lab, have already been sent to the members of the Atomic Weights Commission, by either Michael Berglund or Thomas Walczyk. In the last few days, I checked the published literature for any other articles in the areas of natural variations in isotopic abundance ratios, measurements of isotopic abundance ratios on samples of extra-terrestrial material and isotopic abundance ratio measurements performed using ICPMS instruments. Hopefully this information will be of interest to members of the Commission, the sub-committee on isotopic abundance measurements (SIAM), members of the former sub-committee on natural isotopic fractionation (SNIF), the sub-committee on extra-terrestrial isotope ratios (SETIR), the RTCE Task Group and the Guidelines Task Group, who are dealing with ICPMS and TIMS comparisons. In the following report, I categorize the publications in one of four areas. Measurements performed using either positive or negative ions with Thermal Ionization Mass Spectrometer, TIMS, instruments; measurements performed on Inductively Coupled Plasma Mass Spectrometer, ICPMS, instruments; measurements of natural variations of the isotopic abundance ratios; and finally measurements on extra-terrestrial samples with instrumentation of either type. There is overlap in these areas. I selected out variations and ET results first and then categorized the rest of the papers by TIMS and ICPMS.

    Occupational cancer epidemiology has led to the identification of more than 40 agents, groups of agents, and exposure circumstances which cause cancer in humans. This evidence has been followed by preventive and control measures. There are four areas where occupational cancer epidemiology may contribute important results in the future: surveillance of workers exposed to carcinogens, identification of new carcinogens and target organs, study of interactions, and research on special exposure circumstances.

    The peculiar motion of galaxies can be a particularly sensitive probe of gravitational collapse. As such, it can be used to measure the dynamics of dark matter and dark energy as well the nature of the gravitational laws at play on cosmological scales. Peculiar motions manifest themselves as an overall anisotropy in the measured clustering signal as a function of the angle to the line-of-sight, known as redshift-space distortion (RSD). Limiting factors in this measurement include our ability to model non-linear galaxy motions on small scales and the complexities of galaxy bias. The anisotropy in the measured clustering pattern in redshift-space is also driven by the unknown distance factors at the redshift in question, the Alcock-Paczynski distortion. This weakens growth rate measurements, but permits an extra geometric probe of the Hubble expansion rate. In this chapter we will briefly describe the scientific background to the RSD technique, and forecast the potential of the SKA phase 1 and the SKA2 to measu...

  19. Burnout in occupational therapists.

    Rogers, J C; Dodson, S C

    1988-12-01

    Burnout is a job-related condition involving feelings of emotional exhaustion, depersonalization, and reduced personal accomplishment. The Maslach Burnout Inventory (Maslach & Jackson, 1981a) is the instrument most widely used to measure job-related stress in human service professions, such as occupational therapy. This study explored the application of the Maslach Burnout Inventory for use with occupational therapists. The subjects were 99 registered occupational therapists residing in the southeastern United States. Mean scores lower than the aggregate occupational norms provided by the test's authors on the Emotional Exhaustion and Depersonalization subscales supported the need to develop specific norms for occupational therapists. Results of this study indicate that use of the aggregate norms would underestimate the level of experienced burnout. Correlational analyses delineated significant relationships between age and Emotional Exhaustion and Depersonalization, education and Emotional Exhaustion and Depersonalization, years of work as an occupational therapist and Depersonalization and Personal Accomplishment, years in the present position and Personal Accomplishment (intensity only), hours of direct patient contact and Emotional Exhaustion (intensity only), and hours of direct patient contact and Depersonalization (frequency only). These correlates of burnout furnish clues for understanding the development of work-related stress in occupational therapists.

    We made a series of surveys to obtain neutrino beam line direction toward SuperKamiokande (SK) at a distance of 250 km for the long- baseline neutrino oscillation experiment at KEK. We found that the beam line is directed to SK within 0.03 mr and 0.09 mr (in sigma) in the horizontal and vertical directions, respectively. During beam operation, we monitored the muon distribution from secondary pions produced at the target and collected by a magnetic horn system. We found that the horn system functions like a lens of a point-to- parallel optics with magnification of approximately -100 and the focal length of 2.3 m. Namely, a small displacement of the primary beam position at the target is magnified about a factor -100 at the muon centroid, while the centroid position is almost stable against a change of the incident angle of the primary beam. Therefore, the muon centroid can be a useful monitor of the neutrino beam direction. We could determine the muon centroid within 6 mm and 12 mm in horizontal and vertical ...

    that the minimum mass sum of sum m_nu ~ 0.06 eV in the normal hierarchy can be detected at 1.5 sigma to 2.5 sigma significance, depending on the model complexity, using a combination of galaxy and cosmic shear power spectrum measurements in conjunction with CMB temperature and polarisation observations from Planck....... With better knowledge of the galaxy bias, the significance of the detection could potentially reach 5.4 sigma. Interestingly, neither Planck+shear nor Planck+galaxy alone can achieve this level of sensitivity; it is the combined effect of galaxy and cosmic shear power spectrum measurements that breaks...... the persistent degeneracies between the neutrino mass, the physical matter density, and the Hubble parameter. Notwithstanding this remarkable sensitivity to sum m_nu, Euclid-like shear and galaxy data will not be sensitive to the exact mass spectrum of the neutrino sector; no significant bias (sigma...

  2. Neuropeptide Y stimulation as primary target for preventive measures of maladaptative cardiovascular reactions in occupational chronic stress exposure.

    2012-01-01

    Chronic stress may produce a decrease in central NPY expression and subjects exposed to it may prove hypersensitivity to a novel stressor with dysfunctions in the NPY system and cardiovascular maladaptation to stress, even hypertension. Upregulation of NPY expression may contribute to successful behavioral adaptation to stress by reducing cardiovascular tone and suppressing anxious behaviors. Adaptogens, a new class of metabolic regulators stimulate NPY expression and release. The aim of this study is to increase tolerance and adaptation to stress of hypersensitive to novel stressor, occupational chronic stress exposed subjects with cardiovascular maladaptation to mild new stressor using adaptogens as part of prevention protocol. 40 military personnel with known cardiostressor reactional mode and occupational chronic stress exposure were exposed to mild novel stressor: occupational medicine routine evaluation and clinically assessed for maladaptative cardiovascular response prior and before application of 30 day prevention protocol. Employees were randomly split in two groups, one receiving standard prevention protocol (lifestyle counseling) plus adaptogens in multiple dose administration, twice daily and the other receiving only standard prevention protocol. We found significant statistic differences in all cardiovascular parameters in adaptogen group and only in diastolic blood pressure in control group. Adaptogens could be an important factor in successful prevention protocols of chronic occupational stress dysfunctions involving NPY systems.

    Create a screening measure of health literacy for use with the Health Information National Trends Survey (HINTS). Participants completed a paper-based survey. Items from the survey were used to construct a health literacy screening measure. A population-based survey conducted in geographic areas of high and low minority frequency and in Central Appalachia. Two thousand nine hundred four English-speaking participants were included in this study: 66% white, 93% completed high school, mean age = 52.53 years (SD = 16.24). A health literacy screening measure was created using four items included in the HINTS survey. Scores could range from 0 (no questions affirmative/correct) to 4 (all questions answered affirmatively/correctly). Multiple regression analysis was used to determine whether demographic variables known to predict health literacy were indeed associated with the constructed health literacy screening measure. The weighted average health literacy score was 2.63 (SD = 1.00). Those who were nonwhite (p = .0005), were older (p literacy screening measure scores. This study highlights the need to assess health literacy in national surveys, but also serves as evidence that screening measures can be created within existing datasets to give researchers the ability to consider the impact of health literacy. © The Author(s) 2016.

    The Advanced Camera for Surveys (ACS) Virgo Cluster Survey is a large program to image 100 early-type Virgo galaxies using the F475W and F850LP bandpasses of the Wide Field Channel of the ACS instrument on the Hubble Space Telescope (HST). The scientific goals of this survey include an exploration of the three-dimensional structure of the Virgo Cluster and a critical examination of the usefulness of the globular cluster luminosity function as a distance indicator. Both of these issues require accurate distances for the full sample of 100 program galaxies. In this paper, we describe our data reduction procedures and examine the feasibility of accurate distance measurements using the method of surface brightness fluctuations (SBF) applied to the ACS Virgo Cluster Survey F850LP imaging. The ACS exhibits significant geometrical distortions due to its off-axis location in the HST focal plane; correcting for these distortions by resampling the pixel values onto an undistorted frame results in pixel correlations tha...

    Reference intervals are commonly considered to allow for between-laboratory bias. The RCPAQAP Liquid Serum Chemistry Program has collected data on laboratory measurements as well as reference intervals. This allows assessment of the between-laboratory variation in results, reference intervals and the information transmitted by the combination of these factors. For the majority of common chemistry analytes, the between-laboratory variation in reference intervals is greater than the variation in results. Additionally the reference interval variation is generally not related to bias between the results. Use of common reference intervals, either as an average of the current intervals in use, or the intervals proposed by the AACB Harmonisation Group, improved the variation seen in the information produced by different laboratories.

    Teamwork in health care settings is widely recognized as an important factor in providing high-quality patient care. However, the behaviors that comprise effective teamwork, the organizational factors that support teamwork, and the relationship between teamwork and patient outcomes remain empirical questions in need of rigorous study. To identify and review survey instruments used to assess dimensions of teamwork so as to facilitate high-quality research on this topic. We conducted a systematic review of articles published before September 2012 to identify survey instruments used to measure teamwork and to assess their conceptual content, psychometric validity, and relationships to outcomes of interest. We searched the ISI Web of Knowledge database, and identified relevant articles using the search terms team, teamwork, or collaboration in combination with survey, scale, measure, or questionnaire. We found 39 surveys that measured teamwork. Surveys assessed different dimensions of teamwork. The most commonly assessed dimensions were communication, coordination, and respect. Of the 39 surveys, 10 met all of the criteria for psychometric validity, and 14 showed significant relationships to nonself-report outcomes. Evidence of psychometric validity is lacking for many teamwork survey instruments. However, several psychometrically valid instruments are available. Researchers aiming to advance research on teamwork in health care should consider using or adapting one of these instruments before creating a new one. Because instruments vary considerably in the behavioral processes and emergent states of teamwork that they capture, researchers must carefully evaluate the conceptual consistency between instrument, research question, and context.

  13. Occupations of SSI recipients who work.

    2009-01-01

    This article uses the 2007 American Community Survey to estimate the occupational distribution of Supplemental Security Income (SSI) disability recipients aged 18-61 who work, and it compares their occupational distribution with that of working nonrecipients with and without disabilities. Based on models of occupational choice for working SSI recipients and nonrecipients, predicted occupational distributions are also estimated to understand what occupations are available to SSI recipients. Unlike the nonrecipient populations that are largely composed of sales- and office-based occupations (25 percent), the most common occupations of SSI recipients who work are in services (34 percent) and production, transportation, and material moving (30 percent), although sales- and office-based occupations are also common for SSI recipients (22 percent). The occupational distribution of working SSI recipients is also more concentrated than that of nonrecipient populations. Dissimilarity indices are used to compare the predicted and actual occupational distributions of the SSI recipient population and nonrecipient populations. More than one-half of the difference between the occupations of working SSI recipients and nonrecipients can be explained by demographic characteristics, human capital, and disability type. Additionally, nonemployed SSI recipients have similar predicted occupational distributions as currently employed SSI recipients. Given the estimated occupational distributions and the average earnings of individuals in the most common occupations of SSI recipients, the results suggest that more targeted vocational training may provide expanded opportunities for employment.

  14. Dopamine D{sub 2} receptor occupancy in normal humans treated with a novel antipsychotic drug YKP1358 measured by PET and [11c]raclopride

    YKP1358 is a novel serotonin (5-HT{sub 2A}) and dopamine (D{sub 2}) antagonist, and fitted the general profile of an atypical neuroleptic agent in preclinical studies. The time course of D{sub 2} receptor occupancy in the brain of living human after a single oral dose of YKP1358 was measured using PET and related to the plasma drug levels. A single oral dose, dose escalation (100 mg, 200 mg, and 250 mg), open-label study was performed in 9 healthy male volunteers (3 per each dose) using the [{sup 11}C]raclopried PET. After the baseline scan, each subject was studied at 2, 5, and 10 hours after the single administration of YKP1358. Blood samples for evaluation of plasma concentration of YKP1358 were also taken at various time points (0-32 hours post-dose). Binding potential (BP) of [{sup 11}C]raclopride in the putamen was estimated with simplified reference tissue model and percent reduction of the BP was calculated to obtain the D{sub 2} receptor occupancy. BP parametric image was generated using a pixel-wise Logan noninvasive plot. T{sub max} of plasma concentration-time profiles was 0.67 hours, and elimination half-life was 5.71, 7.46, and 8.58 hours in 100 mg, 200 mg, and 250 mg dosing groups, respectively. D{sub 2} receptor occupancy of YKP1358 was 60 to 80% at 2 hours, 40 to 60% at 5 hours, and 20 to 50% at 10 hours. The relationship of plasma concentration and D{sub 2} receptor occupancy of YKP1358 was well predicted by Emax model, and Emax was 100 %, EC50 was 8.9 (=1.1) ng/mI, and Hills coefficient was 0.525. PK profile of YKP1358 showed individual variation, but the D{sub 2} receptor occupancy was less variable and well predicted by an Emax model. Since D{sub 2} antagonists show therapeutic effects at 50 to 80% D{sub 2} occupancy and the EC50 of YKP1358 is less than 10 ng/ml, doses of YKP1358 which maintain plasma concentrations above 10 ng/ml are expected to show therapeutic effects.

    The measured redshift ($z$) of an astronomical object is a combination of Hubble recession, gravitational redshift and peculiar velocity. In particular, the line of sight distance to a galaxy inferred from redshift is affected by the peculiar velocity component of galaxy redshift, which can also be observed as an anisotropy in the correlation function. This anisotropy allows us to measure the linear growth rate of matter ($f\\sigma_8$). In this paper, we measure the linear growth rate of matter ($f\\sigma_8$) at $z=0.57$ using the CMASS sample from Data Release 11 of Sloan Digital Sky Survey III (SDSS III) Baryon Oscillations Spectroscopic Survey (BOSS). The galaxy sample consists of 690,826 Luminous Red Galaxies (LRGs) in the redshift range 0.43 to 0.7 covering 8498 deg$^2$. Here we report the first measurement of $f\\sigma_8$ and cosmology using Convolution Lagrangian Perturbation Theory (CLPT) with Gaussian streaming model (GSRSD). We arrive at a constraint of $f\\sigma_8=0.462\\pm0.041$ (9\\% accuracy) at effec...

    Bias is a common artificial error during sampling survey in eye diseases, and is a major impact factor for validity and reliability of the survey. The causes and the control measures of several biases regarding current sampling survey of eye diseases in China were analyzed and discussed, including the sampling bias, non-respondent bias, and diagnostic bias. This review emphasizes that controlling bias is the key to ensure quality of sampling survey. Random sampling, sufficient sample quantity, careful examination and taking history, improving examination rate, accurate diagnosis, strict training and preliminary study, as well as quality control can eliminate or minimize biases and improve the sampling survey quality of eye diseases in China

    1999-03-01

    Throughout the automotive industry there has been an increasing concern and focus on the thermal comfort of occupants. Manufacturers are continuously striving to improve heating and air conditioning performance to comply with expanding customer needs. To optimize these systems, the technology to acquire data must also be enhanced. In this evaluation, the standard use of isolated thermocouple location technology is compared to utilizing infrared thermal vision in an air conditioning performance assessment. Infrared data on an actual occupant is correlated to breath and air conditioning output temperatures measured by positioned thermocouples. The use of infrared thermal vision highlights various areas of comfort and discomfort experienced by the occupant. The evaluation involves utilizing an infrared thermal vision camera to film an occupant in the vehicle as the following test procedure is run. The vehicle is soaked in full sun load until the interior temperature reaches a minimum of 150 degrees F (65.6 degrees Celsius). The occupant enters the vehicle and takes an initial temperature reading. The air conditioning is turned on to full cold, full fan speed, and recirculation mode. While being filmed, the driver drives for sixty minutes at 30 miles per hour (48.3 kph). The thermocouples acquire data in one minute intervals while the infrared camera films the cooling process of the occupant.

    Collecting physical measurements in population-based health surveys has increased in recent years, yet little is known about the characteristics of those who consent to these measurements. To examine the characteristics of persons who consent to physical measurements across several domains, including one's demographic background, health status, resistance behavior toward the survey interview, and interviewer characteristics. We conducted a secondary data analysis of the 2006 Health and Retirement Study, a nationally-representative panel survey of older adults aged 51 and older. We performed multilevel logistic regressions on a sample of 7457 respondents who were eligible for physical measurements. The primary outcome measure was consent to all physical measurements. Seventy-nine percent (unweighted) of eligible respondents consented to all physical measurements. In weighted multilevel logistic regressions controlling for respondent demographics, current health status, survey resistance indicators, and interviewer characteristics, the propensity to consent was significantly greater among Hispanic respondents matched with bilingual Hispanic interviewers, patients with diabetes, and those who visited a doctor in the past 2 years. The propensity to consent was significantly lower among younger respondents, those who have several Nagi functional limitations and infrequently participate in "mildly vigorous" activities, and those interviewed by black interviewers. Survey resistance indicators, such as number of contact attempts and interviewer observations of resistant behavior in prior wave iterations of the Health and Retirement Study were also negatively associated with physical measurement consent. The propensity to consent was unrelated to prior medical diagnoses, including high blood pressure, cancer (excluding skin), lung disease, heart abnormalities, stroke, and arthritis, and matching of interviewer and respondent on race and gender.

    By surveying new fields for the shortest-period "big" planets, the Kepler spacecraft could provide the statistics to more clearly measure the occurrence distributions of giant and medium planets. This would allow separate determinations for giant and medium planets of the relationship between the inward rate of tidal migration of planets and the strength of the stellar tidal dissipation (as expressed by the tidal quality factor Q). We propose a "Hot Big Planets Survey" to find new big planets...

  4. Will kinematic Sunyaev-Zel'dovich measurements enhance the science return from galaxy redshift surveys?

    Yes. Future CMB experiments such as Advanced ACTPol and CMB-S4 should achieve measurements with S/N of > 0.1 for the typical host halo of galaxies in redshift surveys. These measurements will provide complementary measurements of the growth rate of large scale structure f and the expansion rate of the Universe H to galaxy clustering measurements. This paper emphasizes that there is significant information in the anisotropy of the relative pairwise kSZ measurements. We expand the relative pairwise kSZ power spectrum in Legendre polynomials and consider up to its octopole. Assuming that the noise in the filtered maps is uncorrelated between the positions of galaxies in the survey, we derive a simple analytic form for the power spectrum covariance of the relative pairwise kSZ temperature in redshift space. While many previous studies have assumed optimistically that the optical depth of the galaxies τT in the survey is known, we marginalize over τT, to compute constraints on the growth rate f and the expansion rate H. For realistic survey parameters, we find that combining kSZ and galaxy redshift survey data reduces the marginalized 1-σ errors on H and f to ~50-70% compared to the galaxy-only analysis.

    To examine perceived stress across employees with different occupational status, to investigate the impact of stress on work ability and to derive conclusions regarding health promotion activities. A comprehensive survey combining questionnaire and medical examination was offered in one division in BASF Ludwigshafen. Among 867 voluntary participants, 653 returned complete questionnaires. The questions were directed at perception of safety at the workplace, self-rated health status, frequency of stress symptoms, unrealistic job demands, time pressure and maladjustment of work life balance. The outcome of interest was self-estimated health measured by the Work Ability Index (WAI). Occupational stressors were perceived differently across occupational status groups. Frontline operators had more health concerns due to workplace conditions, while professional and managerial staff reported higher frequencies of perceived tension, time pressure, and maladjustment of work life balance. After adjustment for occupational status, demographic and lifestyle factors, perceived stress was associated with a modest to strong decline in WAI scores. While perceived occupational stress had an apparent impact on WAI, and WAI has been demonstrated to be predictive of early retirement, more intensive and employee group-specific stress management interventions are being implemented beyond traditional strategies of routine occupational medical surveillance.

    The purpose of this work is to give a contribution to the construction of a comprehensive knowledge of the exposure levels to gradient magnetic fields (GMF) in terms of the weighed peak (WP), especially for 3 Tesla scanners for which there are still few works available in the literature. A new generation probe for the measurement of electromagnetic fields in the range of 1 Hz-400 kHz was used to assess the occupational exposure levels to the GMF for 1.5 and 3.0 Tesla MRI body scanners, using the method of the WP according to the International Commission on Non-Ionizing Radiation Protection (ICNIRP) approach. The probe was placed at a height of 1.1 m, close to the MRI scanners, where operators could stay during some medical procedures with particular issues. The measurements were performed for a set of typical acquisition sequences for body (liver) and head exams. The measured values of WP were in compliance with ICNIRP 2010 reference levels for occupational exposures.

  13. The effect of occupational meaningfulness on occupational commitment

    2014-11-01

    Full Text Available Existing research lacks a scholarly consensus on how to define and validly measure ‘meaningful work’ (e.g., Rosso, Dekas & Wrzesniewski, 2010. The following correlational study highlights the value of investigating meaningfulness in the context of occupational commitment. The study hypothesizes that occupational commitment is positively correlated with occupational meaningfulness, where meaningfulness is defined as the extent to which people’s occupations contribute to personal meaning in life. One-hundred and fifty-six full-time office based UK workers completed an online questionnaire including 18 questions measuring levels of occupational commitment (Meyer, Allen & Smith, 1993, in addition to six novel items measuring occupational meaningfulness. The results supported the hypothesis and also showed that the affective sub-type of occupational commitment had the highest correlation with occupational meaningfulness. Such results exhibit the importance of finding meaning at work, as well as the relevance of this to one’s level of commitment to his or her job. This paper argues that individuals should consider OM before choosing to take a specific role, whereas organizations ought to consider the OM of their potential candidates before recruiting them into a role. Possible directions for future research directions are also discussed.

    Although data on industry and occupation (I&O) are important for understanding cancer risks, obtaining standardized data is challenging. This study describes the capture of specific I&O text and the ability of a web-based tool to translate text into standardized codes. Data on 62 525 cancers cases received from eight National Program of Cancer Registries (NPCR) states were submitted to a web-based coding tool developed by the National Institute for Occupational Safety and Health for translation into standardized I&O codes. We determined the percentage of sufficiently analyzable codes generated by the tool. Using the web-based coding tool on data obtained from chart abstraction, the NPCR cancer registries achieved between 48% and 75% autocoding, but only 12-57% sufficiently analyzable codes. The ability to explore associations between work-related exposures and cancer is limited by current capture and coding of I&O data. Increased training of providers and registrars, as well as software enhancements, will improve the utility of I&O data. © 2017 Wiley Periodicals, Inc.

    Health examination surveys (HESs) provide valuable data on health and its determinants at the population level. Comparison of HES results within and between countries and over time requires measurements which are free of bias due to differences in or adherence to measurement procedures and/or measurement devices. In the European HES (EHES) Pilot Project, 12 countries conducted a pilot HES in 2010-11 using standardized measurement protocols and centralized training. External evaluation visits (site visits) were performed by the EHES Reference Centre staff to evaluate the success of standardization and quality of data collection. In general, standardized EHES protocols were followed adequately in all the pilot surveys. Small deviations were observed in the posture of participants during the blood pressure and height measurement; in the use of a tourniquet when drawing blood samples; and in the calibration of measurement devices. Occasionally, problems with disturbing noise from outside or people coming into the room during the measurements were observed. In countries with an ongoing national HES or a long tradition of conducting national HESs at regular intervals, it was more difficult to modify national protocols to fulfil EHES requirements. The EHES protocols to standardize HES measurements and procedures for collection of blood samples are feasible in cross-country settings. The prerequisite for successful standardization is adequate training. External and internal evaluation activities during the survey fieldwork are also needed to monitor compliance to standards. © The Author 2017.

    Full Text Available Business survey liquidity measure is one of the modifications of the uniform EU business survey methodology applied in Croatia. Consequent liquidity problem have been, since socialist times, one of the major problem for Croatia's business. The problem rapidly increased between 1995 and 2000 and now it again represents the main difficulty for the Croatian economy. In order to improve the forecasting properties of business survey liquidity measure, some econometric models ware applied. Based on the regression analysis we concluded that the changes in the liquidity variable can predict the direction of changes in industrial production with one quarter lead. The results also show that liquidity can be a proxy of the Industrial Confidence Indicator in the observed period. The empirical analysis was performed using quarterly data covering the period from the first quarter 2005 to the fourth quarter 2011. The data sources were Privredni vjesnik (a business magazine in Croatia and the Croatian Bureau of Statistics.

  18. Subjectivity of LiDAR-Based Offset Measurements: Results from a Public Online Survey

    Geomorphic features (e.g., stream channels) that are offset in an earthquake can be measured to determine slip at that location. Analysis of these and other offset features can provide useful information for generating fault slip distributions. Remote analyses of active fault zones using high-resolution LiDAR data have recently been pursued in several studies, but there is a lack of consistency between users both for data analysis and results reporting. Individual investigators typically make offset measurements in a particular study area with their own protocols for measurement, assessing uncertainty, and quality rating, yet there is no coherent understanding of the reliability and repeatability of the measurements from observer to observer. We invited the participation of colleagues, interested geoscience communities, and the general public to measure ten geomorphic offsets from active faults in western North America using remote measurement methods that span a range of complexity (e.g., paper image and scale, the Google Earth ruler tool, and a MATLAB GUI for calculating backslip required to properly restore tectonic deformation) to explore the subjectivity involved with measuring geomorphic offsets. We provided a semi-quantitative quality-rating rubric for a description of offset quality, but there was a general lack of quality rating/offset uncertainty reporting. Survey responses (including mapped fault traces and piercing lines) were anonymously submitted along with user experience information. We received 11 paper-, 28 Google Earth-, and 16 MATLAB-based survey responses, though not all individuals measured every feature provided. For all survey methods, the majority of responses are in close agreement. However, large discrepancies arise where users interpret landforms differently, specifically the pre-earthquake morphologies and total offset accumulation of geomorphic features. Experienced users make more consistent measurements, whereas beginners less

    Policy-makers can use a menu of pharmaceutical policy options. This study aimed to survey these measures that were implemented in European countries between 2010 and 2015. We did bi-annual surveys with competent authorities of the Pharmaceutical Pricing and Reimbursement Information network. Additionally, we consulted posters produced by members of this network as well as further published literature. Information on 32 European countries (all European Union Member States excluding Luxembourg; Iceland, Norway, Serbia, Switzerland, Turkey) was included. 557 measures were reported between January 2010 and December 2015. The most frequently mentioned measure was price reductions and price freezes, followed by changes in patient co-payments, modifications related to the reimbursement lists and changes in distribution remuneration. Most policy measures were identified in Portugal, Greece, Belgium, France, the Czech Republic, Iceland, Spain and Germany. 22% of the measures surveyed could be classified as austerity. Countries that were strongly hit by the financial crisis implemented most policy changes, usually aiming to generate savings and briefly after the emergence of the crisis. Improvements in the economic situation tended to lead to an easing of austerity measures. Countries also implemented policies that aimed to enhance enforcement of existing measures and increase efficiency. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  1. Zoonoses as occupational diseases

    Directory of Open Access Journals (Sweden)

    Giorgio Battelli

    2008-12-01

    Full Text Available Zoonoses are discussed as occupational diseases, with special reference to animal husbandry and related activities. After quoting some historical references, occupational zoonoses are examined in relation to the evolution of the concept of occupational zoonosis, the involvement of the World Health Organization in this field, their socio-economic significance, the principal working activities, zoonoses of greatest importance (with special reference to the Mediterranean region, the evaluation of damage and risks. An outline is made of the transmission of zoonoses from farm workers to animals and the biological hazards from the environment. The present situation of occupational zoonoses and related risks in industrialised and traditional farming activities are presented and the importance of some emerging and re-emerging zoonoses for the health of workers is highlighted. The author concludes by stressing that the prevention of occupational zoonoses must be implemented jointly by both veterinary and medical services through preventive measures and epidemiological surveillance of human and animal health, risk evaluation, diagnosis of infections and prompt reporting. It is hoped that the future will offer better inter-disciplinary collaboration and that legislation will be timely and better tailored to safeguard working health and safety.

  6. Measuring cosmic velocities with 21cm intensity mapping and galaxy redshift survey cross-correlation dipoles

    CERN Document Server

    Hall, Alex

    2016-01-01

    We investigate the feasibility of measuring the effects of peculiar velocities in large-scale structure using the dipole of the redshift-space cross-correlation function. We combine number counts of galaxies with brightness-temperature fluctuations from 21cm intensity mapping, demonstrating that the dipole may be measured at modest significance ($\\lesssim 2\\sigma$) by combining the upcoming radio survey CHIME with the future redshift surveys of DESI and Euclid. More significant measurements ($\\lesssim~10\\sigma$) will be possible by combining intensity maps from the SKA with these of DESI or Euclid, and an even higher significance measurement ($\\lesssim 100\\sigma$) may be made by combining observables completely internally to the SKA. We account for effects such as contamination by wide-angle terms, interferometer noise and beams in the intensity maps, non-linear enhancements to the power spectrum, stacking multiple populations, sensitivity to the magnification slope, and the possibility that number counts and...

    1997-12-31

    The Norwegian Radiation Protection Authority (NRPA) took part in the international survey measurement exercise RESUME95 that was arranged in Finland in August 1995. NRPA performed measurements with a simple car-borne measuring system based on standard equipment, a 3x3` NaI detector, an MCA and a GPS connected to a portable PC. The results show substantial variations in dose rate inside areas of a few square kilometres. Spectrum analysis shows that a major part of these differences are caused by variations in deposition of {sup 137}Cs. Our results show that even standard 3x3` NaI detectors can be used for car based survey measurements in fall out situations and search for sources. The detection limits are higher than for larger detectors, but the main limiting factor seem to be the timing capabilities of the acquisition system. (au).

    2015-12-01

    To harmonize measures of cognitive performance using item response theory (IRT) across two international aging studies. Data for persons ≥65 years from the Health and Retirement Study (HRS, N = 9,471) and the English Longitudinal Study of Aging (ELSA, N = 5,444). Cognitive performance measures varied (HRS fielded 25, ELSA 13); 9 were in common. Measurement precision was examined for IRT scores based on (a) common items, (b) common items adjusted for differential item functioning (DIF), and (c) DIF-adjusted all items. Three common items (day of date, immediate word recall, and delayed word recall) demonstrated DIF by survey. Adding survey-specific items improved precision but mainly for HRS respondents at lower cognitive levels. IRT offers a feasible strategy for harmonizing cognitive performance measures across other surveys and for other multi-item constructs of interest in studies of aging. Practical implications depend on sample distribution and the difficulty mix of in-common and survey-specific items. © The Author(s) 2015.

  15. Mitigating Systematic Errors in Angular Correlation Function Measurements from Wide Field Surveys

    CERN Document Server

    Morrison, Christopher Brian

    2015-01-01

    We present an investigation into the effects of survey systematics such as varying depth, point spread function (PSF) size, and extinction on the galaxy selection and correlation in photometric, multi-epoch, wide area surveys. We take the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS) as an example. Variations in galaxy selection due to systematics are found to cause density fluctuations of up to 10% for some small fraction of the area for most galaxy redshift slices and as much as 50% for some extreme cases of faint high-redshift samples. This results in correlations of galaxies against survey systematics of order $\\sim$1% when averaged over the survey area. We present an empirical method for mitigating these systematic correlations from measurements of angular correlation functions using weighted random points. These weighted random catalogs are estimated from the observed galaxy over densities by mapping these to survey parameters. We are able to model and mitigate the effect of systematic correl...

    We explore the potential of using intensity mapping surveys (MeerKAT, SKA) and optical galaxy surveys (DES, LSST) to detect HI clustering and weak gravitational lensing of 21cm emission in auto- and cross-correlation. Our forecasts show that high precision measurements of the clustering and lensing signals can be made in the near future using the intensity mapping technique. Such studies can be used to test the intensity mapping method, and constrain parameters such as the HI density $\\Omega_{\\rm HI}$, the HI bias $b_{\\rm HI}$ and the galaxy-HI correlation coefficient $r_{\\rm HI-g}$.

Such studies can be used to test the intensity mapping method, and constrain parameters such as the H I density Ω _{H I}, the H I bias b_{H I} and the galaxy-H I correlation coefficient r_{H I-g}.

    Yes. Future CMB experiments such as Advanced ACTPol and CMB-S4 should achieve measurements with S/N of $> 0.1$ for the typical galaxies in redshift surveys. These measurements will provide complementary measurements of the growth rate of large scale structure $f$ and the expansion rate of the Universe $H$ to galaxy clustering measurements. This paper emphasizes that there is significant information in the anisotropy of the relative pairwise kSZ measurements. We expand the relative pairwise kSZ power spectrum in Legendre polynomials and consider up to its octopole. Assuming that the noise in the filtered maps is uncorrelated between the positions of galaxies in the survey, we derive a simple analytic form for the power spectrum covariance of the relative pairwise kSZ temperature in redshift space. While many previous studies have assumed optimistically that the optical depth of the galaxies $\\tau_{\\rm T}$ in the survey is known, we marginalize over $\\tau_{\\rm T}$, to compute constraints on the growth rate $f$ ...

    Physiotherapy and occupational therapy professionals are at high risk of developing occupational musculoskeletal injuries globally. Musculoskeletal pain is the most common problem. To determine the extent of discomfort that physiotherapy and occupational therapy health professionals report while working at a physical rehabilitation centre. Physiotherapy and occupational therapy professionals which include both graduate and diploma physiotherapists and occupational therapists as well as physiotherapy and occupational therapy assistants. A self administered questionnaire (survey) was conducted on a convenient sample of 101 physiotherapy and occupational therapy personnel. The mean age of the 101 participants was 27.8 (± 4.5) years and most of the participants (62%) had less than 5 years of work experience. Ninety-five percent of the participants complained of work related pain. Most of the participants reported pain in the lower back (n=84) followed by upper back (n=71) and neck (n=66). Significant associations were found for pain in ankles/feet with age (p=0.05) and pain in neck with gender (p=0.01). Physiotherapy and occupational therapy professionals suffer from pain in relation to the work they do as therapists which may be due to non-practice of appropriate body mechanics. Mechanism to assess level of practice during dealing with patients may be introduced to enable corrective measures. Incentives should be considered for appropriate practice.

    To understand the changing trend of occupational hazard of industries in Shunde area and to provide the scientific evidence for the prevention of occupational diseases. The pre-evaluation of occupational hazard was carried out for the construction projects. The data about employee number scale, industry species, occupational hazard factors, hazard levels and prevention measures for construction projects were collected and analyzed. The data of Shunde Occupational Health Survey in 2011 served as the control data. There were 258 construction projects in 2010 and 2011, in which the proportions of medium and large scales increased to 8.1% and 2.4% respectively, the proportions of the furniture and chemical industries decreased from 25.6% or/and 5.1% to 2.7% or/and 1.8%, the proportions of the high-tech industries increased from 1.8% to 9.2%. The proportions of the projects with serious, medium and slight occupational hazard levels were 4.3%, 67.8% and 27.9%, respectively. The proportions of the projects with harmful chemicals, dusts and physical factors were 34.2%, 46.8%, 42.6%, respectively. The feature of occupational hazard in Shunde industries has changed at upgrading stage. We should pay attention to the prevention of occupational diseases in high-tech industries.

    Two common methods used to measure indicators for health programme monitoring and evaluation are the demographic and health surveys (DHS) and lot quality assurance sampling (LQAS); each one has different strengths. We report on both methods when utilised in comparable situations. We compared 24 indicators in south-west Uganda, where data for prevalence estimations were collected independently for the two methods in 2011 (LQAS: n = 8876; DHS: n = 1200). Data were stratified (e.g. gender and age) resulting in 37 comparisons. We used a two-sample two-sided Z-test of proportions to compare both methods. The average difference between LQAS and DHS for 37 estimates was 0.062 (SD = 0.093; median = 0.039). The average difference among the 21 failures to reject equality of proportions was 0.010 (SD = 0.041; median = 0.009); among the 16 rejections, it was 0.130 (SD = 0.010, median = 0.118). Seven of the 16 rejections exhibited absolute differences of 0.10 and 0.20 (mean = 0.261, SD = 0.083). There is 75.7% agreement across the two surveys. Both methods yield regional results, but only LQAS provides information at less granular levels (e.g. the district level) where managerial action is taken. The cost advantage and localisation make LQAS feasible to conduct more frequently, and provides the possibility for real-time health outcomes monitoring. © 2015 The Authors.

    Late stage failures of candidate drug molecules are frequently caused by off-target effects or inefficient target engagement in vivo. In order to address these fundamental challenges in drug discovery, we developed a modular probe strategy based on bioorthogonal chemistry that enables the attachment of multiple reporters to the same probe in cell extracts and live cells. In a systematic evaluation, we identified the inverse electron demand Diels-Alder reaction between trans-cyclooctene labeled probe molecules and tetrazine-tagged reporters to be the most efficient bioorthogonal reaction for this strategy. Bioorthogonal biotinylation of the probe allows the identification of drug targets in a chemoproteomics competition binding assay using quantitative mass spectrometry. Attachment of a fluorescent reporter enables monitoring of spatial localization of probes as well as drug-target colocalization studies. Finally, direct target occupancy of unlabeled drugs can be determined at single cell resolution by competitive binding with fluorescently labeled probe molecules. The feasibility of the modular probe strategy is demonstrated with noncovalent PARP inhibitors.

    2013-01-01

    The next generation of wide-field spectroscopic redshift surveys will map the large-scale galaxy distribution in the redshift range 0.7< z<2 to measure baryonic acoustic oscillations (BAO). The primary optical signature used in this redshift range comes from the [OII] emission line doublet, which provides a unique redshift identification that can minimize confusion with other single emission lines. To derive the required spectrograph resolution for these redshift surveys, we simulate observations of the [OII] (3727,3729) doublet for various instrument resolutions, and line velocities. We foresee two strategies about the choice of the resolution for future spectrographs for BAO surveys. For bright [OII] emitter surveys ([OII] flux ~30.10^{-17} erg /cm2/s like SDSS-IV/eBOSS), a resolution of R~3300 allows the separation of 90 percent of the doublets. The impact of the sky lines on the completeness in redshift is less than 6 percent. For faint [OII] emitter surveys ([OII] flux ~10.10^{-17} erg /cm2/s like ...

    [Abridged] We exploit the synergy between low-resolution spectroscopy and photometric redshifts to study environmental effects on galaxy evolution in slitless spectroscopic surveys from space. As a test case, we consider the future Euclid Deep survey (~40deg$^2$), which combines a slitless spectroscopic survey limited at H$\\alpha$ flux $\\leq5\\times 10^{-17}$ erg cm$^{-2}$ s$^{-1}$ and a photometric survey limited in H-band ($H\\leq26$). To test the power of the method, we use Euclid-like galaxy mock catalogues, in which we anchor the photometric redshifts to the 3D galaxy distribution of the available spectroscopic redshifts. We then estimate the local density contrast by counting objects in cylindrical cells with radius ranging from 1 to 10 h$^{-1}$Mpc over the redshift range 0.9survey (H=26) but without redshift measurement errors. We find that our method is successful in separating hi...

    Full Text Available Institutions of higher education that respond to the economic base in their region will remain competitive and be better positioned to obtain public funds and donor support. In addition to mandated program viability standards based on measures such as graduation rate, individual institutions and state coordinating boards can use ten-year occupational trend data to assess future program viability. We used an occupational demand model to determine whether academic programs can meet projected statewide needs for high demand and high growth occupations. For example, computer engineering, the highest growth rate occupation in Alabama, is projected to have 365 annual average job openings, with 93.6% total growth over ten years. But only 46 computer engineering majors graduate annually from all Alabama institutions of higher education. We recommend using an occupational demand model as a planning tool, decision-making tool, and catalyst for collaborative initiatives.

    We present the first regional trends in anuran occupancy for eight states of the southeastern United States, based on 13 y (2001–2013) of North American Amphibian Monitoring Program (NAAMP) data. The NAAMP is a longterm monitoring program in which observers collect anuran calling observation data at fixed locations along random roadside routes. We assessed occupancy trends for 14 species. We found weak evidence for a general regional pattern of decline in calling anurans within breeding habitats along roads in the southeastern USA over the last 13 y. Two species had positive regional trends with 95% posterior intervals that did not include zero (Hyla cinerea and Pseudacris crucifer). Five other species also showed an increasing trend, while eight species showed a declining trend, although 95% posterior intervals included zero. We also assessed state level trends for 107 species/state combinations. Of these, 14 showed a significant decline and 12 showed a significant increase in occupancy (i.e., credible intervals did not include zero for these 26 trends).

    The [α/Fe] ratios in stars are good tracers to probe the formation history of stellar populations and the chemical evolution of the Galaxy. The spectroscopic survey of LAMOST provides a good opportunity to determine [α/Fe] of millions of stars in the Galaxy. We present a method of measuring the [α/Fe] ratios from LAMOST spectra using the template-matching technique of the LSP3 pipeline. We use three test samples of stars selected from the ELODIE and MILES libraries, as well as the LEGUE survey to validate our method. Based on the test results, we conclude that our method is valid for measuring [α/Fe] from low-resolution spectra acquired by the LAMOST survey. Within the range of the stellar parameters T eff = [5000, 7500] K, log g = [1.0, 5.0] dex and [Fe/H]= [-1.5, +0.5] dex, our [α/Fe] measurements are consistent with values derived from high-resolution spectra, and the accuracy of our [α/Fe] measurements from LAMOST spectra is better than 0.1 dex with spectral signal-to-noise higher than 20.

    2017-01-01

    Introduction The blood test for high-sensitivity cardiac troponin T (HS-CTnT) has been proposed as a marker of cardiovascular risk in the general population, as it is associated with subsequent incidence of cardiovascular events and mortality. We aimed at evaluating the feasibility of HS-CTnT testing within large nationally-representative population surveys in which blood samples are collected during household visits, shipped using the standard civil postal service, and then frozen for subsequent analyses. Methods The Health Survey for England (HSE) consists of a series of annual surveys beginning in 1991. It is designed to provide regular information on various aspects of the nation’s health and risk factors. We measured HS-CTnT in the blood of 200 people from the HSE 2016 wave, then froze and stored their blood samples at -40°C for 5–10 weeks, and then thawed and retested them to appreciate the extent of within-person agreement or test-retest reliability of the two measurements. Results The Cronbach's Alpha (Scale Reliability Coefficient) and the Interclass Correlation Coefficient (two-way mixed-effects model for consistency of agreement at individual level) were 0.97 (95%CI = 0.96–0.99) and 0.95 (95%CI = 0.94–0.96) respectively. The time delay from blood withdrawal to analysis and storage (1–4 days) did not affect the results, nor did the freezing time before the retest (5–10 weeks). Conclusion The measurement of HS-CTnT plasma concentration within large nationally-representative surveys such as the Health Survey for England is feasible. PMID:28141863

    Full Text Available This article provides a survey and a general methodology for coexistence studies between digital terrestrial television (DTT and mobile broadband (MBB systems in the ultra high frequency (UHF broadcasting band. The methodology includes characterization of relevant field measurement scenarios and gives a step-by-step guideline on how to obtain reliable field measurement results to be used in conjunction with link budget analyses, laboratory measurements, and simulations. A survey of potential European coexistence scenarios and regulatory status is given to determine feasible future use scenarios for the UHF television (TV broadcasting band. The DTT reception system behavior and performance are also described as they greatly affect the amount of spectrum potentially available for MBB use and determine the relevant coexistence field measurement scenarios. Simulation methods used in determining broadcast protection criteria and in coexistence studies are briefly described to demonstrate how the information obtained from field measurements can be used to improve their accuracy. The presented field measurement guidelines can be applied to any DTT-MBB coexistence scenarios and to a wide range of spectrum sharing and cognitive radio system coexistence measurements.

  4. Pitfalls with weight for height measurements in surveys of acute malnutrition.

    Science.gov (United States)

    Soeters, R

    1986-10-01

    A combined survey of weight for height measurement was done by 2 emergency aid organizations. The same 131 children were measured independently by 2 survey teams. 1 team measured 24.4% and the other team 47.7% of the 131 children as under 80% weight/height. The serious logistical consequences of these differences for the emergency aid program are discussed. The main cause of the difference was observer error. A reason for systematic bias could be that an observer using the Nabarro chart tends to classify children who are slightly above 80% as under 80%. This bias is understandable because one does not want to miss out malnourished children. This systematic bias does not occur when weight and height are measured separately and the % read from a card. The importance of following a strict protocol when measuring is stressed. Another less important cause for the different results was that the teams used 2 weight for height standards. The use of 2 standards in the same Oxfam kit is unfortunate. It would be better to choose 1 uniform standard, to avoid misinterpretations. The Nabarro chart is the quickest method for weight/height measurement, but is prone to observer error. The method in which weight and height are measured separately and the % read from a chart is more reliable. A plea is made for the use of uniform standards.

  5. Measuring the velocity field from type Ia supernovae in an LSST-like sky survey

    2016-01-01

    With the upcoming sky survey with the Large Synoptic Survey Telescope a great sample of type Ia supernovae will be observed, allowing for a precise mapping of the velocity structure of the universe. Since the source of peculiar velocities is variations in the density field, cosmological parameters related to the matter distribution can subsequently be extracted from the velocity power spectrum. One way to quantify this is through the angular power spectrum of radial peculiar velocities on spheres at different redshifts. We investigate how well this observable can be measured, despite the problems caused by areas with no information. To obtain a realistic distribution of supernovae, we create mock supernova catalogs by using a semi-analytical code for galaxy formation on the merger trees extracted from N-body simulations. We measure the cosmic variance in the velocity power spectrum by repeating the procedure many times for differently located observers, and vary different aspects of the analysis, such as the ...

    2010-05-01

    In the hydropower industry, it is important to have precise information about snow deposits at all times, to allow for effective planning and optimal use of the water. In Norway, it is common to measure snow density using a manual method, i.e. the depth and weight of the snow is measured. In recent years, radar measurements have been taken from snowmobiles; however, few energy supply companies use this method operatively - it has mostly been used in connection with research projects. Agder Energi is the first Norwegian power producer in using radar tecnology from helicopter in monitoring mountain snow levels. Measurement accuracy is crucial when obtaining input data for snow reservoir estimates. Radar screening by helicopter makes remote areas more easily accessible and provides larger quantities of data than traditional ground level measurement methods. In order to draw up a snow survey system, it is assumed as a basis that the snow distribution is influenced by vegetation, climate and topography. In order to take these factors into consideration, a snow survey system for fields in high mountain areas has been designed in which the data collection is carried out by following the lines of a grid system. The lines of this grid system is placed in order to effectively capture the distribution of elevation, x-coordinates, y-coordinates, aspect, slope and curvature in the field. Variation in climatic conditions are also captured better when using a grid, and dominant weather patterns will largely be captured in this measurement system.

    We exploit the synergy between low-resolution spectroscopy and photometric redshifts to study environmental effects on galaxy evolution in slitless spectroscopic surveys from space. As a test case, we consider the future Euclid Deep survey (˜40 deg2), which combines a slitless spectroscopic survey limited at Hα flux ≥5 × 10-17 erg cm-2 s-1 and a photometric survey limited in H band (H ≤ 26). We use Euclid-like galaxy mock catalogues, in which we anchor the photometric redshifts to the 3D galaxy distribution of the available spectroscopic redshifts. We then estimate the local density contrast by counting objects in cylindrical cells with radius from 1 to 10 h-1Mpc, over the redshift range 0.9 < z < 1.8. We compare this density field with the one computed in a mock catalogue with the same depth as the Euclid Deep survey (H = 26) but without redshift measurement errors. We find that our method successfully separates high- from low-density environments (the last from the first quintile of the density distribution), with higher efficiency at low redshift and large cells: the fraction of low-density regions mistaken by high-density peaks is <1 per cent for all scales and redshifts explored, but for scales of 1 h-1Mpc for which is a few per cent. These results show that we can efficiently study environment in photometric samples if spectroscopic information is available for a smaller sample of objects that sparsely samples the same volume. We demonstrate that these studies are possible in the Euclid Deep survey, i.e. in a redshift range in which environmental effects are different from those observed in the local Universe, hence providing new constraints for galaxy evolution models.

    Full Text Available A student self-determination profile of occupational and educational choices was examined through the concepts of Locus of Causality and Locus of Orientation. Research questions associated with respondents’ certainty of occupation and orientation to vocational education were answered. The tested hypotheses were as follows: (a Independence, initiative, self-guidance, choice of discussion forums, and gender are related to certainty of future occupation choice and choice of vocational education; (b certainty of occupation relates to choosing vocational education; (c negatively biased media lessens interest in vocational education; and (d vocational education choices are related to gender. A survey of ninth-grade students in Finnish comprehensive school was conducted after implementation of a work-orientation program defined in the national comprehensive school curriculum. At the local school system level, 649 subjects of the mean ages of 16.0 years participated in an Internet survey in two school districts in southwestern Finland in 2008. The variables were inserted in Linear Multiple Regression Analysis in IBM SPSS. The means of vocational school choice and certainty of occupation, and vocational school choice and negative media image were compared in SPSS means. An independent-samples t test for vocational school choice and sex was conducted. Statistically significant regression models of loci of orientation and locus of causality were found. The more the respondents were certain of their occupation choice, the more they expressed their secondary education orientation to be vocational school. When students discussed their choices less at home, their orientation to vocational education weakened. A negative media image was not associated with vocational school choice in this data. The measured means for girls’ and boys’ orientations to vocational school did not show statistically significant differences.

    Full Text Available Household income is difficult to measure, since it requires the collection of information about all potential income sources for each member of a household.Weassess the effects of two types of edit check questions on measurement error and survey estimates: within-wave edit checks use responses to questions earlier in the same interview to query apparent inconsistencies in responses; dependent interviewing uses responses from prior interviews to query apparent inconsistencies over time.Weuse data from three waves of the British Household Panel Survey (BHPS to assess the effects of edit checks on estimates, and data from an experimental study carried out in the context of the BHPS, where survey responses were linked to individual administrative records, to assess the effects on measurement error. The findings suggest that interviewing methods without edit checks underestimate non-labour household income in the lower tail of the income distribution. The effects on estimates derived from total household income, such as poverty rates or transition rates into and out of poverty, are small.

    The Planck CMB experiment has delivered the best constraints so far on primordial non-Gaussianity, ruling out early-Universe models of inflation that generate large non-Gaussianity. Although small improvements in the CMB constraints are expected, the next frontier of precision will come from future large-scale surveys of the galaxy distribution. The advantage of such surveys is that they can measure many more modes than the CMB—in particular, forthcoming radio surveys with the Square Kilometre Array will cover huge volumes. Radio continuum surveys deliver the largest volumes, but with the disadvantage of no redshift information. In order to mitigate this, we use two additional observables. First, the integrated Sachs-Wolfe effect—the cross-correlation of the radio number counts with the CMB temperature anisotropies—helps to reduce systematics on the large scales that are sensitive to non-Gaussianity. Second, optical data allows for cross-identification in order to gain some redshift information. We show that, while the single redshift bin case can provide a σ(f{sub NL}) ∼ 20, and is therefore not competitive with current and future constraints on non-Gaussianity, a tomographic analysis could improve the constraints by an order of magnitude, even with only two redshift bins. A huge improvement is provided by the addition of high-redshift sources, so having cross-ID for high-z galaxies and an even higher-z radio tail is key to enabling very precise measurements of f{sub NL}. We use Fisher matrix forecasts to predict the constraining power in the case of no redshift information and the case where cross-ID allows a tomographic analysis, and we show that the constraints do not improve much with 3 or more bins. Our results show that SKA continuum surveys could provide constraints competitive with CMB and forthcoming optical surveys, potentially allowing a measurement of σ(f{sub NL}) ∼ 1 to be made. Moreover, these measurements would act as a useful check

    Full Text Available Objetivo: Caracterizar colectivos de inmigrantes trabajadores en España y conocer sus condiciones de salud laboral mediante informantes clave. Método: Estudio cualitativo exploratorio-descriptivo con entrevistas en profundidad realizado en 2006. Se identificaron organizaciones, asociaciones y colectivos relacionados con la población inmigrante en Alicante, Barcelona, Huelva, Madrid y Valencia, y se seleccionaron los más accesibles y representativos. Se entrevistó a 43 informantes clave procedentes de 34 asociaciones u organismos. Se realizó un análisis narrativo del contenido. Resultados: Se señalan dificultades para el reconocimiento de los daños a la salud derivados del trabajo por las situaciones de irregularidad y precariedad, por resistencia por parte de los contratadores o las entidades aseguradoras, y por desconocimiento de los inmigrantes. Los informantes coinciden en que los riesgos laborales en los inmigrantes no difieren de los riesgos de los trabajadores autóctonos en similares circunstancias, pero los inmigrantes padecerían exposiciones más frecuentes e intensas por el acceso mayoritario a puestos menos cualificados y por la necesidad de prolongar las jornadas de trabajo. También se destaca su desconocimiento general en relación con los derechos de protección y de salud en el trabajo, aunque algunos informantes detectan un crecimiento de su actividad reivindicativa a través de los sindicatos. Conclusiones: Este primer acercamiento ha permitido definir algunos condicionantes generales que influirán en la salud laboral de los inmigrantes. La información obtenida servirá de base para profundizar, mediante técnicas adicionales de carácter cualitativo y cuantitativo, en los problemas de salud laboral de los inmigrantes trabajadores en España dentro del marco del Proyecto Inmigración, Trabajo y Salud (ITSAL, actualmente en desarrollo.Objective: To describe the characteristics, working conditions, and occupational

    The Workspace Satisfaction Survey measures occupant satisfaction with the thermal, lighting, acoustical, and air quality aspects of the work environment. In addition to ratings of these ambient environmental features, occupants also rate their satisfaction with a number of functional and aesthetic features of the office environment as well as their satisfaction with specific kinds of workspaces (e.g., computer rooms, the lobby, employee lounge, etc.). Each section on ambient conditions includes questions on the frequency with which people experience particular kinds of discomforts or problems, how much the discomfort bothers them, and how much it interferes with their work. Occupants are also asked to identify how they cope with discomfort or environmental problems, and to what extent these behaviors enable them to achieve more satisfactory conditions. This report documents the results of this survey of the occupants of the Emerald People's Utility District office building in Eugene, Oregon.

    2010-06-01

    Full Text Available Abstract Background Patient safety is a critical component to the quality of health care. As health care organizations endeavour to improve their quality of care, there is a growing recognition of the importance of establishing a culture of patient safety. In this research, the authors use the Hospital Survey on Patient Safety Culture (HSOPSC questionnaire to assess the culture of patient safety in Taiwan and attempt to provide an explanation for some of the phenomena that are unique in Taiwan. Methods The authors used HSOPSC to measure the 12 dimensions of the patient safety culture from 42 hospitals in Taiwan. The survey received 788 respondents including physicians, nurses, and non-clinical staff. This study used SPSS 15.0 for Windows and Amos 7 software tools to perform the statistical analysis on the survey data, including descriptive statistics and confirmatory factor analysis of the structural equation model. Results The overall average positive response rate for the 12 patient safety culture dimensions of the HSOPSC survey was 64%, slightly higher than the average positive response rate for the AHRQ data (61%. The results showed that hospital staff in Taiwan feel positively toward patient safety culture in their organization. The dimension that received the highest positive response rate was "Teamwork within units", similar to the results reported in the US. The dimension with the lowest percentage of positive responses was "Staffing". Statistical analysis showed discrepancies between Taiwan and the US in three dimensions, including "Feedback and communication about error", "Communication openness", and "Frequency of event reporting". Conclusions The HSOPSC measurement provides evidence for assessing patient safety culture in Taiwan. The results show that in general, hospital staffs in Taiwan feel positively toward patient safety culture within their organization. The existence of discrepancies between the US data and the Taiwanese data

    For the enforcement of the {rho}a-{rho}u survey method which is a type of high-density electrical survey, a multichannel resistivity measuring instrument has been developed. This instrument, in addition to the above, conducts resistivity tomography and various other kinds of high-density electrical survey. A potential produced by a low frequency rectangular current of 1Hz or lower outputted by the transmitter of this instrument is received and measured by the receiver connected to electrodes positioned at 100 or less locations. The receiver comprises a scanner that automatically switches from electrode to electrode, conditioner that processes signals, and controller. A transmitter of the standard design outputs a maximum voltage of 800V and maximum current of 2A, making a device suitable for probing 50 to several 100m-deep levels. The receiver is operated by a personal computer that the controller is provided with. The newly-developed apparatus succeeded in presenting high-precision images of the result of a {rho}a-{rho}u analysis for an apparent resistivity section and of the underground structure, verifying the high quality of the data collected by this apparatus. 10 refs., 5 figs., 1 tab.

    Full Text Available Research question: What is the extent of problem of maternal mortality in a given population? Objective: 1. To evolve a rapid survey methodology aimed at measuring maternal mortality ratio. 2. To find out the probable medical causes of maternal deaths and behavioural factors associated with them. Study Design: cross- sectional. Setting: Urban and rural areas of district Mohindergarh, Haryana. Participants: Members of families in which a maternal death had taken place in last 12 months. Sample size: All 275 deaths among women 15-44 years occurring in the district from 1st April 95 to 31st March 96. Study variables: Age, gravida, parity, literacy, caste, land holding, health care facilities, distance from health centers, mode of conveyance. Statistical Analysis: Rates and ratios. Results: Maternal mortality ratio was estimated to be 275 per 100,000 live births (298 rural and 82 urban. Major causes of death were â€" sepsis(30%, haemorrhage (21%, abortion(5%, eclampsia (3% and obstructed labour(3%. Twenty-nine causes of deaths occurred at home and 26% on way to hospital. Out of 59(93.7% cases who could avail medical consultation, 61% arranged it within five hours after onset of symptoms, and 78% availed two, 21% three, and 11% four consulations. The survey was completed in three months at a cost of Rs. 54,000. Recommendations: Such rapid surveys should be carried out periodically (every 4-5 years to monitor the progress in maternal health. Staff of heath deptt. Should be involved in carrying out these surveys. This will not only help in reducing cost of the survey but information about specific problems of maternal mortality in the area can be utilized by health staff for taking appropriate action to improve maternal health care.

    Reliability coefficients indicate the proportion of total variance attributable to differences among measures separated along a quantitative continuum by a testing, survey, or assessment instrument. Reliability is usually considered to be influenced by both the internal consistency of a data set and the number of items, though textbooks and research papers rarely evaluate the extent to which these factors independently affect the data in question. Probabilistic formulations of the requirements for unidimensional measurement separate consistency from error by modelling individual response processes instead of group-level variation. The utility of this separation is illustrated via analyses of small sets of simulated data, and of subsets of data from a 78-item survey of over 2,500 parents of children with disabilities. Measurement reliability ultimately concerns the structural invariance specified in models requiring sufficient statistics, parameter separation, unidimensionality, and other qualities that historically have made quantification simple, practical, and convenient for end users. The paper concludes with suggestions for a research program aimed at focusing measurement research more on the calibration and wide dissemination of tools applicable to individuals, and less on the statistical study of inter-variable relations in large data sets.

    Full Text Available Abstract Background While increasing attention is placed on using evidence-based decision making (EBDM to improve public health, there is little research assessing the current EBDM capacity of the public health workforce. Public health agencies serve a wide range of populations with varying levels of resources. Our survey tool allows an individual agency to collect data that reflects its unique workforce. Methods Health department leaders and academic researchers collaboratively developed and conducted cross-sectional surveys in Kansas and Mississippi (USA to assess EBDM capacity. Surveys were delivered to state- and local-level practitioners and community partners working in chronic disease control and prevention. The core component of the surveys was adopted from a previously tested instrument and measured gaps (importance versus availability in competencies for EBDM in chronic disease. Other survey questions addressed expectations and incentives for using EBDM, self-efficacy in three EBDM skills, and estimates of EBDM within the agency. Results In both states, participants identified communication with policymakers, use of economic evaluation, and translation of research to practice as top competency gaps. Self-efficacy in developing evidence-based chronic disease control programs was lower than in finding or using data. Public health practitioners estimated that approximately two-thirds of programs in their agency were evidence-based. Mississippi participants indicated that health department leaders' expectations for the use of EBDM was approximately twice that of co-workers' expectations and that the use of EBDM could be increased with training and leadership prioritization. Conclusions The assessment of EBDM capacity in Kansas and Mississippi built upon previous nationwide findings to identify top gaps in core competencies for EBDM in chronic disease and to estimate a percentage of programs in U.S. health departments that are evidence

    Health care employees are often women, a group that has high degrees of sick leave and perhaps problems attaining occupational balance. However, people think differently about their everyday activities and it is therefore important to take their perceptions into account but occupational balance has not yet been measured in health professionals. The aim was to describe occupational balance in three different samples of health professionals in Sweden. A further aim was to investigate whether occupational therapists (OTs) rate their occupational balance differently from other health professionals. Four hundred and eighty-two health professionals, employees in public dentistry, mental health care and OTs, aged 21-70 years participated. The participants' occupational balance was measured using the occupational balance questionnaire (OBQ). The ratings of occupational balance were similar to earlier studies and did not differ significantly between the samples. The OTs' occupational balance was also similar to that of the other health professionals. The similarities in occupational balance indicate the same difficulties in attaining it. The result highlights the possibility that working people face similar difficulties in achieving occupational balance. Further research is warranted about how to attain it.

    2010-11-01

    Full Text Available Abstract Background Comparable health measures across different sets of populations are essential for describing the distribution of health outcomes and assessing the impact of interventions on these outcomes. Self-reported health (SRH is a commonly used indicator of health in household surveys and has been shown to be predictive of future mortality. However, the susceptibility of SRH to influence by individuals' expectations complicates its interpretation and undermines its usefulness. Methods This paper applies the empirical methodology of Lindeboom and van Doorslaer (2004 to investigate elderly health in India using data from the 52nd round of the National Sample Survey conducted in 1995-96 that includes both an SRH variable as well as a range of objective indicators of disability and ill health. The empirical testing was conducted on stratified homogeneous groups, based on four factors: gender, education, rural-urban residence, and region. Results We find that region generally has a significant impact on how women perceive their health. Reporting heterogeneity can arise not only from cut-point shifts, but also from differences in health effects by objective health measures. In contrast, we find little evidence of reporting heterogeneity due to differences in gender or educational status within regions. Rural-urban residence does matter in some cases. The findings are robust with different specifications of objective health indicators. Conclusions Our exercise supports the thesis that the region of residence is associated with different cut-points and reporting behavior on health surveys. We believe this is the first paper that applies the Lindeboom-van Doorslaer methodology to data on the elderly in a developing country, showing the feasibility of applying this methodology to data from many existing cross-sectional health surveys.

    Safety climate evaluation is increasingly used by hospitals as part of quality improvement initiatives. Consequently, it is necessary to have validated tools to measure changes. To evaluate the construct validity and internal consistency of a survey tool to measure Australian hospital pharmacy patient safety climate. A 42 item cross-sectional survey was used to evaluate the patient safety climate of 607 Australian hospital pharmacy staff. Survey responses were initially mapped to the factor structure previously identified in European community pharmacy. However, as the data did not adequately fit the community pharmacy model, participants were randomly split into two groups with exploratory factor analysis performed on the first group (n = 302) and confirmatory factor analyses performed on the second group (n = 305). Following exploratory factor analysis (59.3% variance explained) and confirmatory factor analysis, a 6-factor model containing 28 items was obtained with satisfactory model fit (χ(2) (335) = 664.61 p  0.643) and model nesting between the groups (Δχ(2) (22) = 30.87, p = 0.10). Three factors (blame culture, organisational learning and working conditions) were similar to those identified in European community pharmacy and labelled identically. Three additional factors (preoccupation with improvement; comfort to question authority; and safety issues being swept under the carpet) highlight hierarchical issues present in hospital settings. This study has demonstrated the validity of a survey to evaluate patient safety climate of Australian hospital pharmacy staff. Importantly, this validated factor structure may be used to evaluate changes in safety climate over time. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background Population-based sample surveys and sentinel surveillance methods are commonly used as substitutes for more widespread health and demographic monitoring and intervention studies in resource-poor settings. Such methods have been criticised as only being worthwhile if the results can be extrapolated to the surrounding 100-fold population. With an emphasis on measuring mortality, this study explores the extent to which choice of sampling method affects the representativeness of 1% sample data in relation to various demographic and health parameters in a rural, developing-country setting. Methods Data from a large community based census and health survey conducted in rural Burkina Faso were used as a basis for modelling. Twenty 1% samples incorporating a range of health and demographic parameters were drawn at random from the overall dataset for each of seven different sampling procedures at two different levels of local administrative units. Each sample was compared with the overall 'gold standard' survey results, thus enabling comparisons between the different sampling procedures. Results All sampling methods and parameters tested performed reasonably well in representing the overall population. Nevertheless, a degree of variation could be observed both between sampling approaches and between different parameters, relating to their overall distribution in the total population. Conclusion Sample surveys are able to provide useful demographic and health profiles of local populations. However, various parameters being measured and their distribution within the sampling unit of interest may not all be best represented by a particular sampling method. It is likely therefore that compromises may have to be made in choosing a sampling strategy, with costs, logistics the intended use of the data being important considerations.

    A light-weight UAV system for coastal topography and coastal sea surface measurements is developed. This system is based on techniques of a multirotor UAV, a light detection and ranging (LIDAR), an inertial measurement unit, and a real-time kinematic global navigation satellite system (RTK-GNSS). The synchronization and data recording are achieved using Labview. This system can be operated in a very low attitude flight within a range of 10m that can provide very high resolution of point cloud data. The performance of this system has been tested and calibrated with known targets. The vertical root-mean-square error is less than about 10 cm, depending on the flight height. Applications of the system, including coastal topographic surveys, tidal elevation measurement, wave measurements, and bottom roughness measurements are presented and discussed. The tide and wave measurements are compared with in-situ measurements using pressure sensors. The results of comparison suggest that this system is a useful tool to measure the sea surface elevation and topography. The challenges of applying this system are also discussed.

    Stress is a nonspecific reaction to everything the body needs. Although occupational stress exists in every occupation, it is seen with more frequency and intensity amongst those occupations related to human health. In this study, we aimed to investigate the relationship between occupational stress and social support (SS) among hospital nurses. A cross-sectional survey was conducted among 1144 hospital nurse in China. They were investigated with a self-administered questionnaire about socio-demographic characteristics, occupational stress and social support. A validated version of the revised Occupational Stress Inventory (OSI-R) was applied to evaluate occupational stress; SS was measured by nine questions. Logistic regression analysis was used to study the association between occupational stress and SS and adjusted for income, gender, marital status, working years, educational level, and profession. Of 1144 nurses, the majority age group was less than 30 years, and the mean age across participants was 31.8 years. Further correlation analysis indicated that score of ORQ and PSQ had a significant negative correlation with score of SS (P<0.05), and a significant positive correlation was found between Score of PRQ and score of SS (P<0.05). The univariate analysis and multivariate analysis results also revealed that high SS increased significantly with decreasing ORQ score and increasing PRQ score after controlling for income, gender, marital status, working years, educational level and job title. SS significantly influences occupational stress in hospitals nurse. We also should pay more attention to occupational stress of married and long working years nurse.

    Divers may run a higher risk of infection with waterborne pathogens than bathers because of more frequent and intense contact with water that may not comply with microbiologic water quality standards for bathing water. In this study we aimed to estimate the volume of water swallowed during diving as a key factor for infection risk assessment associated with diving. Using questionnaires, occupational and sport divers in the Netherlands were asked about number of dives, volume of swallowed water, and health complaints (nausea, vomiting, diarrhea, and ear, skin, eye, and respiratory complaints). Occupational divers, on average, swallowed 9.8 mL marine water and 5.7 mL fresh surface water per dive. Sport divers swallowed, on average, 9.0 mL marine water; 13 mL fresh recreational water; 3.2 mL river, canal, or city canal water; and 20 mL water in circulation pools. Divers swallowed less water when wearing a full face mask instead of an ordinary diving mask and even less when wearing a diving helmet. A full face mask or a diving helmet is recommended when diving in fecally contaminated water. From the volumes of swallowed water and concentrations of pathogens in fecally contaminated water, we estimated the infection risks per dive and per year to be as high as a few to up to tens of percents. This may explain why only 20% of the divers reported having none of the inquired health complaints within a period of 1 year. It is highly recommended that divers be informed about fecal contamination of the diving water. PMID:16675425

    Occupational noise is a frequently encountered on-the-job health hazard. This guide presented the responsibilities and regulatory requirements related to business activities where noise above 80 decibels is present. The guide provided a definition of noise and discussed noise hazards, types of noise, and on-the-job noise exposure. A risk assessment to noise in the work environment was also discussed. A guide to a hearing conservation program was also included. The main purpose of a hearing conservation program is the prevention of noise induced hearing loss for employees exposed to occupational noise. The components of such a program were outlined, with particular reference to noise monitoring; noise exposure control; worker education and training; hearing (audiometric) testing; and annual program review and record keeping. It was concluded that in terms of record keeping, it can be very helpful to file noise exposure assessments, particularly personal exposure measurements, with hearing test records to facilitate for future reference. refs., appendices.

    Disruptive intraoperative behavior has detrimental effects to clinicians, institutions, and patients. How clinicians respond to this behavior can either exacerbate or attenuate its effects. Previous investigations of disruptive behavior have used survey scales with significant limitations. The study objective was to develop appropriate scales to measure exposure and responses to disruptive behavior. We obtained ethics approval. The scales were developed in a sequence of steps. They were pretested using expert reviews, computational linguistic analysis, and cognitive interviews. The scales were then piloted on Canadian operating room clinicians. Factor analysis was applied to half of the data set for question reduction and grouping. Item response analysis and theoretical reviews ensured that important questions were not eliminated. Internal consistency was evaluated using Cronbach α. Model fit was examined on the second half of the data set using confirmatory factor analysis. Content validity of the final scales was re-evaluated. Consistency between observed relationships and theoretical predictions was assessed. Temporal stability was evaluated on a subsample of 38 respondents. A total of 1433 and 746 clinicians completed the exposure and response scales, respectively. Content validity indices were excellent (exposure = 0.96, responses = 1.0). Internal consistency was good (exposure = 0.93, responses = 0.87). Correlations between the exposure scale and secondary measures were consistent with expectations based on theory. Temporal stability was acceptable (exposure = 0.77, responses = 0.73). We have developed scales measuring exposure and responses to disruptive behavior. They generate valid and reliable scores when surveying operating room clinicians, and they overcome the limitations of previous tools. These survey scales are freely available.

    Prioritising control measures for occupationally related cancers should be evidence based. We estimated the current burden of cancer in Britain attributable to past occupational exposures for International Agency for Research on Cancer (IARC) group 1 (established) and 2A (probable) carcinogens. We calculated attributable fractions and numbers for cancer mortality and incidence using risk estimates from the literature and national data sources to estimate proportions exposed. 5.3% (8019) cancer deaths were attributable to occupation in 2005 (men, 8.2% (6362); women, 2.3% (1657)). Attributable incidence estimates are 13 679 (4.0%) cancer registrations (men, 10 063 (5.7%); women, 3616 (2.2%)). Occupational attributable fractions are over 2% for mesothelioma, sinonasal, lung, nasopharynx, breast, non-melanoma skin cancer, bladder, oesophagus, soft tissue sarcoma, larynx and stomach cancers. Asbestos, shift work, mineral oils, solar radiation, silica, diesel engine exhaust, coal tars and pitches, occupation as a painter or welder, dioxins, environmental tobacco smoke, radon, tetrachloroethylene, arsenic and strong inorganic mists each contribute 100 or more registrations. Industries and occupations with high cancer registrations include construction, metal working, personal and household services, mining, land transport, printing/publishing, retail/hotels/restaurants, public administration/defence, farming and several manufacturing sectors. 56% of cancer registrations in men are attributable to work in the construction industry (mainly mesotheliomas, lung, stomach, bladder and non-melanoma skin cancers) and 54% of cancer registrations in women are attributable to shift work (breast cancer). This project is the first to quantify in detail the burden of cancer and mortality due to occupation specifically for Britain. It highlights the impact of occupational exposures, together with the occupational circumstances and industrial areas where exposures to carcinogenic agents

    To measure the parameter of job satisfaction among anesthesiologists. Survey instrument. Academic anesthesiology departments in the United States. 320 anesthesiologists who attended the annual meeting of the ASA in 2009 (95% response rate). The anonymous 50-item survey collected information on 26 independent demographic variables and 24 dependent ranked variables of career satisfaction among practicing anesthesiologists. Mean survey scores were calculated for each demographic variable and tested for statistically significant differences by analysis of variance. Questions within each domain that were internally consistent with each other within domains were identified by Cronbach's alpha ≥ 0.7. P-values ≤ 0.05 were considered statistically significant. Cronbach's alpha analysis showed strong internal consistency for 10 dependent outcome questions in the practice factor-related domain (α = 0.72), 6 dependent outcome questions in the peer factor-related domain (α = 0.71), and 8 dependent outcome questions in the personal factor-related domain (α = 0.81). Although age was not a variable, full-time status, early satisfaction within the first 5 years of practice, working with respected peers, and personal choice factors were all significantly associated with anesthesiologist job satisfaction. Improvements in factors related to job satisfaction among anesthesiologists may lead to higher early and current career satisfaction. Copyright © 2013 Elsevier Inc. All rights reserved.

    The assessment of stress is a key issue in health promotion policies as well as in treatment strategies for patients. The aim of this study was to confirm the accessibility and reliability of computer-assisted data collection for perceived stress measurement, using the Japanese version of the Perceived Stress Scale (JPSS), within the setting of a community-based survey. There were two groups of participants in this survey. One group responded to a Web-based application, and the other to the VBA of a spreadsheet software. The total scores of JPSS were almost normally distributed. The means of total scores of JPSS were 23.6 and 23.1. These results were lower than the previous study of JPSS. Since Cronbach's alpha coefficients in both surveys were more than 0.8, high reliability was demonstrated despite a number of computer-illiterate and/or aged participants. They felt that the spreadsheet form was easier to respond to. Two components were extracted with the Varimax rotation of principal component analysis, and these were named "perception of stress and stressors" and "behavior to stress". This finding suggests that it is possible to determine sub-scales. From the viewpoint of preventive medicine, it is expected that the JPSS applications will be utilized to investigate the relationship between stress and other factors such as lifestyle, environment and quality of life.

    Patterns of cervical muscle activity may contribute to overuse injuries in office workers. The purpose of this investigation was to characterise patterns of upper trapezius muscle activity in pain-free office workers using traditional occupational exposure measures and a modified Active Amplitude Probability Distribution Function (APDF), which considers only periods of active muscle contraction. Bilateral trapezius muscle activity was recorded in 77 pain-free office workers for 1-2 full days in their natural work environment. Mean amplitude, gap frequency, muscular rest and Traditional and Active APDF amplitudes were calculated. All measures demonstrated fair to substantial reliability. Dominant muscles demonstrated higher amplitudes of activity and less muscular rest compared to non-dominant, and women demonstrated less muscular rest with no significant difference in amplitude assessed by Active APDF compared to men. These findings provide normative data to identify atypical motor patterns that may contribute to persistence or recurrence of neck pain in office workers. Practitioner Summary: Upper trapezius muscle activity was characterised in a large cohort of pain-free workers using electromyographic recordings from office environments. Dominant muscles demonstrated higher activity and less rest than non-dominant, and women demonstrated less rest than men. Results may be used to identify atypical trapezius muscle activity in office workers.

  9. What does "occupation" represent as an indicator of socioeconomic status?: exploring occupational prestige and health.

    The association between socioeconomic status (SES) and health has been widely documented. However, the role of occupation in this association is not clear because occupation is less often used than income and education as an indicator of SES, especially in the United States. This may be caused by the ambiguity in what occupation represents: both health-enhancing resources (e.g., self-affirmation) and health-damaging hazards (e.g., job stress). SES has two aspects: resources and status. While income and education represent resources and imply status, occupational prestige is an explicit indicator of the social status afforded by one's occupation. Using data from the US General Social Survey in 2002 and 2006 (n = 3151), we examine whether occupational prestige has a significant association with self-rated health independent from other SES indicators (income, education), occupational categories (e.g., managerial, professional, technical, service), and previously established work-related health determinants (job strain, work place social support, job satisfaction). After all covariates were included in the multiple logistic regression model, higher occupational prestige was associated with lower odds of reporting poor/fair self-rated health. We discuss potential mechanisms through which occupational prestige may impact health. Our findings not only suggest multiple ways that occupation is associated with health, but also highlight the utility of occupational prestige as an SES indicator that explicitly represents social standing.

    The aims of this study were to assess the functional level of women with fibromyalgia; to investigate the differences in the occupational activities between women with fibromyalgia and healthy women; and to analyse the perceived importance of occupational performance during self-care, productivity and leisure activities. A cross-sectional case control study was performed. Twenty women with fibromyalgia and 20 healthy women completed the Functional Independence Measure (FIM), the Canadian Occupational Performance Measure (COPM), a Numerical Pain Rating Scale, the Fibromyalgia Impact Questionnaire and the SF-36 health survey. The Chi-square test (χ2), the Student's t test and the Spearman's test were used on the data. The FIM revealed significant differences regarding several activities: personal hygiene, bathing and memory (p  0.10). Women with fibromyalgia had higher disability and reduced quality of life and required greater assistance to perform specific activities of daily living, i.e. hygiene, than healthy women. This highlights the specific occupational therapy needs these women have for performing many basic activities and for improving their quality of life. Limitations of the study include the small sample size, the exclusion of male participants and the possible influence of the women's psychological status on the assessments performed. Findings should be generalized with caution. Copyright © 2015 John Wiley & Sons, Ltd.

    Petrin, Allen J.

    Radio spectrum is a vital national asset; proper management of this finite resource is essential to the operation and development of telecommunications, radio-navigation, radio astronomy, and passive remote sensing services. To maximize the utility of the radio spectrum, knowledge of its current usage is beneficial. As a result, several spectrum studies have been conducted in urban Atlanta, suburban Atlanta, and rural North Carolina. These studies improve upon past spectrum studies by resolving spectrum usage by nearly all its possible parameters: frequency, time, polarization, azimuth, and location type. The continuous frequency range from 400MHz to 7.2 GHz was measured with a custom-designed system. More than 8 billion spectrum measurements were taken over several months of observation. A multi-parameter spectrum usage detection method was developed and analyzed with data from the spectrum studies. This method was designed to exploit all the characteristics of spectral information that was available from the spectrum studies. Analysis of the spectrum studies showed significant levels of underuse. The level of spectrum usage in time and azimuthal space was determined to be only 6.5 % for the urban Atlanta, 5.3 % for suburban Atlanta, and 0.8 % for the rural North Carolina spectrum studies. Most of the frequencies measured never experienced usage. Interference was detected in several protected radio astronomy and sensitive radio navigation bands. A cognitive radio network architecture to share spectrum with fixed microwave systems was developed. The architecture uses a broker-based sharing method to control spectrum access and investigate interference issues.

    This study was designed to evaluate the effectiveness of stress management training workshops within Zeneca Pharmaceuticals. The study was of cross-sectional design, comparing groups of workshop attendees and non-attendees. In addition, self-rated well-being scores of attendees were compared with results obtained pre-workshop and 2-3 months after the workshop. Employees participating in the study were drawn from the Manufacturing, Research and Development, Sales and Marketing sites of Zeneca Pharmaceuticals located in Cheshire, United Kingdom. Three hundred and ninety persons who had participated in stress management workshops since 1988 were matched for age, gender and department with an equal number of employees who had not attended stress management workshops. Outcome measures included self-rated well-being (as measured by the 30-question General Health Questionnaire), knowledge of company guidance on the management of stress in staff, and an assessment of coping strategies. Subjects who had not attended a stress management workshop were much more likely to have a poor understanding of the principles of management of stress in staff [odds ratio (OR) = 8.3; 95% confidence interval (CI) = 3.3-21.3] and more likely to have poor coping skills (OR = 2.8; CI = 1.3-6.1). However, mean scores for the two measures were similar in attendees and non-attendees. Self-rating of current well-being was strongly associated with the life-events score, but not related to workshop attendance. The study indicates that stress management training workshops reduce the prevalence of employees with a poor understanding of the principles of the management of stress in staff and with poor coping strategies. An improvement in the self-rated well-being observed shortly after the workshop was not sustained.

    Infertility is a significant disability, yet there are no reliable estimates of its global prevalence. Studies on infertility prevalence define the condition inconsistently, rendering the comparison of studies or quantitative summaries of the literature difficult. This study analyzed key components of infertility to develop a definition that can be consistently applied to globally available household survey data. We proposed a standard definition of infertility and used it to generate prevalence estimates using 53 Demographic and Health Surveys (DHS). The analysis was restricted to the subset of DHS that contained detailed fertility information collected through the reproductive health calendar. We performed sensitivity analyses for key components of the definition and used these to inform our recommendations for each element of the definition. Exposure type (couple status, contraceptive use, and intent), exposure time, and outcomes were key elements of the definition that we proposed. Our definition produced estimates that ranged from 0.6% to 3.4% for primary infertility and 8.7% to 32.6% for secondary infertility. Our sensitivity analyses showed that using an exposure measure of five years is less likely to misclassify fertile unions as infertile. Additionally, using a current, rather than continuous, measure of contraceptive use over five years resulted in a median relative error in secondary infertility of 20.7% (interquartile range of relative error [IQR]: 12.6%-26.9%), while not incorporating intent produced a corresponding error in secondary infertility of 58.2% (IQR: 44.3%-67.9%). In order to estimate the global burden of infertility, prevalence estimates using a consistent definition need to be generated. Our analysis provided a recommended definition that could be applied to widely available global household data. We also summarized potential biases that should be considered when making estimates of infertility prevalence using household survey data.

    Full Text Available Background: There are more than 40 Health and Demographic Surveillance System (HDSS sites in 19 different countries. The running costs of HDSS sites are high. The financing of HDSS activities is of major importance, and adding external health surveys to the HDSS is challenging. To investigate the ways of improving data quality and collection efficiency in the Nouna HDSS in Burkina Faso, the stand-alone data collection activities of the HDSS and the Household Morbidity Survey (HMS were integrated, and the paper-based questionnaires were consolidated into a single tablet-based questionnaire, the Comprehensive Disease Assessment (CDA. Objective: The aims of this study are to estimate and compare the implementation costs of the two different survey approaches for measuring population health. Design: All financial costs of stand-alone (HDSS and HMS and integrated (CDA surveys were estimated from the perspective of the implementing agency. Fixed and variable costs of survey implementation and key cost drivers were identified. The costs per household visit were calculated for both survey approaches. Results: While fixed costs of survey implementation were similar for the two survey approaches, there were considerable variations in variable costs, resulting in an estimated annual cost saving of about US$45,000 under the integrated survey approach. This was primarily because the costs of data management for the tablet-based CDA survey were considerably lower than for the paper-based stand-alone surveys. The cost per household visit from the integrated survey approach was US$21 compared with US$25 from the stand-alone surveys for collecting the same amount of information from 10,000 HDSS households. Conclusions: The CDA tablet-based survey method appears to be feasible and efficient for collecting health and demographic data in the Nouna HDSS in rural Burkina Faso. The possibility of using the tablet-based data collection platform to improve the quality

    Computerization of physician practices is increasing. Stakeholders are demanding demonstrated value for their Electronic Medical Record (EMR) implementations. We developed survey tools to measure medical office processes, including administrative and physician tasks pre- and post-EMR implementation. We included variables that were expected to improve with EMR implementation and those that were not expected to improve, as controls. We measured the same processes pre-EMR, at six months and 18 months post-EMR. Time required for most administrative tasks decreased within six months of EMR implementation. Staff time spent on charting increased with time, in keeping with our anecdotal observations that nurses were given more responsibility for charting in many offices. Physician time to chart increased initially by 50%, but went down to original levels by 18 months. However, this may be due to the drop-out of those physicians who had a difficult time charting electronically.

    To test the psychometric properties of a newly developed measure of staff nurse clinical leadership derived from Kouzes and Posner's model of transformational leadership. While nurses have been recognized for their essential role in keeping patients safe, there has been little empirical research that has examined clinical leadership at the staff nurse level.   A non-experimental survey design was used to test the psychometric properties of the clinical leadership survey (CLS). Four hundred and eighty registered nurses (RNs) providing direct patient care in Ontario acute care hospitals returned useable questionnaires.   Confirmatory factor analysis provided preliminary evidence for the construct validity for the new measure of staff nurse clinical leadership. Structural empowerment fully mediated the relationship between nursing leadership and staff nurse clinical leadership. The results provide encouraging evidence for the construct validity of the CLS. Nursing administrators must create empowering work environments to ensure staff nurses have access to work structures which enable them to enact clinical leadership behaviours while providing direct patient care. © 2011 The Authors.

    The Sloan Digital Sky Survey (SDSS) surveyed 14,555 square degrees, and delivered over a trillion pixels of imaging data. We present a study of galaxy clustering using 900,000 luminous galaxies with photometric redshifts, spanning between $z=0.45$ and $z=0.65$, constructed from the SDSS using methods described in Ross et al. (2011). This data-set spans 11,000 square degrees and probes a volume of $3h^{-3} \\rm{Gpc}^3$, making it the largest volume ever used for galaxy clustering measurements. We present a novel treatment of the observational systematics and its applications to the clustering signals from the data set. In this paper, we measure the angular clustering using an optimal quadratic estimator at 4 redshift slices with an accuracy of ~15% with bin size of delta_l = 10 on scales of the Baryon Acoustic Oscillations (BAO) (at l~40-400). We derive cosmological constraints using the full-shape of the power-spectra. For a flat Lambda CDM model, when combined with Cosmic Microwave Background Wilkinson Microw...

    (abridged) We describe the automated spectral classification, redshift determination, and parameter measurement pipeline in use for the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey III (SDSS-III) as of Data Release 9, encompassing 831,000 moderate-resolution optical spectra. We give a review of the algorithms employed, and describe the changes to the pipeline that have been implemented for BOSS relative to previous SDSS-I/II versions, including new sets of stellar, galaxy, and quasar redshift templates. For the color-selected CMASS sample of massive galaxies at redshift 0.4 <~ z <~ 0.8 targeted by BOSS for the purposes of large-scale cosmological measurements, the pipeline achieves an automated classification success rate of 98.7% and confirms 95.4% of unique CMASS targets as galaxies (with the balance being mostly M stars). Based on visual inspections of a subset of BOSS galaxies, we find that ~0.2% of confidently reported CMASS sample classifications and redshifts are...

    Full Text Available Purpose: The main purpose of this study is to apply a multigroup confirmatory analysis to examine the measurement invariance (MI of the adapted version of the Job Diagnosis Survey (JDS as a measurement tool that analyses the relationship between the features of teaching methodologies with university students’ motivation and satisfaction across data collected on different degrees and academic years. Design/methodology/approach: Confirmatory factor analysis was carried out using a multigroup structural equation model, using the program EQS 6.1 to test the invariance of the adapted version of JDS in a sample constituted by 535 student of a Spanish public university. The assessment of invariance included the levels of configural, metric, scalar, covariance and latent variables invariance. Several goodness-of-fit measures were assessed. Findings: The results show that measurements are equivalent at the configural, metric, covariance and latent factors invariance. Although the hypotheses of scalar invariance is rejected, results suggest that JDS is partial strict invariant and has satisfactory psychometric properties on all samples. Research limitations/implications: The sample is framed in university students aged between 18 and 30 and for a questionnaire on teaching methodology and students' satisfaction in the context of a Spanish university and the generalization to other questionnaire, or population, should be proved with specific data. Furthermore, the sample size is rather small. Originality/value: In the current process of change that is taking place in universities according to the plan developed by the European Space of Higher Education, focused on increasing the student skills, validate instruments as the satisfaction scale of JDS, are necessary to evaluate students’ satisfaction with new active methodologies. These findings are useful for researchers since they add the first sample in which the MI of a student’s satisfaction survey

    We identified voids in the completed VIMOS Public Extragalactic Redshift Survey (VIPERS), using an algorithm based on searching for empty spheres. We measured the cross-correlation between the centres of voids and the complete galaxy catalogue. The cross-correlation function exhibits a clear anisotropy in both VIPERS fields (W1 and W4), which is characteristic of linear redshift space distortions. By measuring the projected cross-correlation and then deprojecting it we are able to estimate the undistorted cross-correlation function. We propose that given a sufficiently well measured cross-correlation function one should be able to measure the linear growth rate of structure by applying a simple linear Gaussian streaming model for the redshift space distortions (RSD). Our study of voids in 306 mock galaxy catalogues mimicking the VIPERS fields would suggest that VIPERS is capable of measuring $\\beta$ with an error of around $25\\%$. Applying our method to the VIPERS data, we find a value for the redshift space ...

  3. Surveillance indicators for potential reduced exposure products (PREPs: developing survey items to measure awareness

    Full Text Available Abstract Background Over the past decade, tobacco companies have introduced cigarettes and smokeless tobacco products (known as Potential Reduced Exposure Products, PREPs with purportedly lower levels of some toxins than conventional cigarettes and smokeless products. It is essential that public health agencies monitor awareness, interest, use, and perceptions of these products so that their impact on population health can be detected at the earliest stages. Methods This paper reviews and critiques existing strategies for measuring awareness of PREPs from 16 published and unpublished studies. From these measures, we developed new surveillance items and subjected them to two rounds of cognitive testing, a common and accepted method for evaluating questionnaire wording. Results Our review suggests that high levels of awareness of PREPs reported in some studies are likely to be inaccurate. Two likely sources of inaccuracy in awareness measures were identified: 1 the tendency of respondents to misclassify "no additive" and "natural" cigarettes as PREPs and 2 the tendency of respondents to mistakenly report awareness as a result of confusion between PREPs brands and similarly named familiar products, for example, Eclipse chewing gum and Accord automobiles. Conclusion After evaluating new measures with cognitive interviews, we conclude that as of winter 2006, awareness of reduced exposure products among U.S. smokers was likely to be between 1% and 8%, with the higher estimates for some products occurring in test markets. Recommended measurement strategies for future surveys are presented.

    The characterization of exozodiacal light emission is both important for the understanding of planetary systems evolution and for the preparation of future space missions aiming to characterize low mass planets in the habitable zone of nearby main sequence stars. The Large Binocular Telescope Interferometer (LBTI) exozodi survey aims at providing a ten-fold improvement over current state of the art, measuring dust emission levels down to a typical accuracy of 12 zodis per star, for a representative ensemble of 30+ high priority targets. Such measurements promise to yield a final accuracy of about 2 zodis on the median exozodi level of the targets sample. Reaching a 1 σ measurement uncertainty of 12 zodis per star corresponds to measuring interferometric cancellation ("null") levels, i.e visibilities at the few 100 ppm uncertainty level. We discuss here the challenges posed by making such high accuracy mid-infrared visibility measurements from the ground and present the methodology we developed for achieving current best levels of 500 ppm or so. We also discuss current limitations and plans for enhanced exozodi observations over the next few years at LBTI.

    Measurement errors can play a pivotal role in geophysical inversion. Most inverse models require users to prescribe a statistical model of data errors before inversion. Wrongly prescribed error levels can lead to over- or under-fitting of data, yet commonly used models of measurement error are relatively simplistic. With the heightening interests in uncertainty estimation across hydrogeophysics, better characterisation and treatment of measurement errors is needed to provide more reliable estimates of uncertainty. We have analysed two time-lapse electrical resistivity tomography (ERT) datasets; one contains 96 sets of direct and reciprocal data collected from a surface ERT line within a 24h timeframe, while the other is a year-long cross-borehole survey at a UK nuclear site with over 50,000 daily measurements. Our study included the characterisation of the spatial and temporal behaviour of measurement errors using autocorrelation and covariance analysis. We find that, in addition to well-known proportionality effects, ERT measurements can also be sensitive to the combination of electrodes used. This agrees with reported speculation in previous literature that ERT errors could be somewhat correlated. Based on these findings, we develop a new error model that allows grouping based on electrode number in additional to fitting a linear model to transfer resistance. The new model fits the observed measurement errors better and shows superior inversion and uncertainty estimates in synthetic examples. It is robust, because it groups errors together based on the number of the four electrodes used to make each measurement. The new model can be readily applied to the diagonal data weighting matrix commonly used in classical inversion methods, as well as to the data covariance matrix in the Bayesian inversion framework. We demonstrate its application using extensive ERT monitoring datasets from the two aforementioned sites.

    Full Text Available Background: Although low back pain (LBP represents a significant occupational problem for hospital nurses, few investigations target nurses for low back pain and its association with the personal and work-related factors in Iran. Methods: This cross sectional study was performed on 245 nursing personnel (registered nurses, nursing aides, operating room technicians, anesthesiology technicians working full time for at least 1 month at 4 hospitals. Data were collected by modified Nordic questionnaire and interview followed by clinical examination. c2, Mantel and logistic regression statistical tests were used. Results: The 12-month period-prevalence of LBP was 49.9 % (95%CI 43-55/8. In this study 51(21/7% males and 184(78/3% females participated that mean age of them was 32 years .The prevalence of back pain increased with increasing age. There was no differences between the sexes, but more prevalence was observed in the married ones than singles. Odds ratio of LBP was increased 2/2 times with BMI higher than 27kg/m2. In this study the relationship between cumulative duration of employment in nursing job, duration of employment in present ward and manual handling and back pain was significant statistically. Conclusion: LBP is high among nurses. For prevention of LBP, ergonomic program, lifting team, correct lifting technique and wider research with taking into account LBP psychosocial factors and work task are suggested.

    The aim of this work is to evaluate and describe the current status of, and prospects for, the future of occupational hygiene in Finland. The main sources of information include a seminar held in the annual meeting of Finnish Occupational Hygiene Society and interviews with different stakeholders. Nanotechnology and other new materials, changing work environments, circular economy including green jobs, new medical methods and advances of construction methods were recognized as future challenges. Future work opportunities for occupational hygiene experts included exposure assessments in indoor air surveys, private consulting and entrepreneurship in general, international activities and product safety issues. Unclear topics needing more attention in the future were thought to be in new exposures, sensitive persons, combined effects, skin exposures and applicability of personal protective equipment. Occupational hygiene should broaden its view; occupational hygienists should have to cooperate with other specialists and grasp new challenges.

    Prioritising control measures for occupationally related cancers should be evidence based. We estimated the current burden of cancer in Britain attributable to past occupational exposures for International Agency for Research on Cancer (IARC) group 1 (established) and 2A (probable) carcinogens. We calculated attributable fractions and numbers for cancer mortality and incidence using risk estimates from the literature and national data sources to estimate proportions exposed. 5.3% (8019) cancer deaths were attributable to occupation in 2005 (men, 8.2% (6362); women, 2.3% (1657)). Attributable incidence estimates are 13, 679 (4.0%) cancer registrations (men, 10 063 (5.7%); women, 3616 (2.2%)). Occupational attributable fractions are over 2% for mesothelioma, sinonasal, lung, nasopharynx, breast, non-melanoma skin cancer, bladder, oesophagus, soft tissue sarcoma, larynx and stomach cancers. Asbestos, shift work, mineral oils, solar radiation, silica, diesel engine exhaust, coal tars and pitches, occupation as a painter or welder, dioxins, environmental tobacco smoke, radon, tetrachloroethylene, arsenic and strong inorganic mists each contribute 100 or more registrations. Industries and occupations with high cancer registrations include construction, metal working, personal and household services, mining, land transport, printing/publishing, retail/hotels/restaurants, public administration/defence, farming and several manufacturing sectors. 56% of cancer registrations in men are attributable to work in the construction industry (mainly mesotheliomas, lung, stomach, bladder and non-melanoma skin cancers) and 54% of cancer registrations in women are attributable to shift work (breast cancer).

    2017-04-01

    Education on human rights will place occupational therapists in a strong position to address societal inequities that limit occupational engagement for many client groups. The imminent changes to the Minimum Standard for the Education of Occupational Therapists engender efforts towards social change and will require university-level human rights education. This education might enhance the profession's influence on disadvantaging social structures in order to effect social change. To contribute to the evidence base for social change education in occupational therapy, this research aims to understand the knowledge, skills, confidence and learning experiences of occupational therapy students who completed a human rights course. Final year occupational therapy students responded to questionnaires which included listing human rights, a human rights scale measuring knowledge and confidence for working towards human rights, and open questions. Numbers of rights listed, knowledge scores and confidence scores were calculated. Responses to the open questions were thematically analysed. After completing a human rights course, students had good knowledge and moderate confidence to work with human rights. Three themes were identified including 'learning about human rights', 'learning about structural, societal and global perspectives on occupational engagement' and 'learning how occupational therapists can work with groups, communities and populations: becoming articulate and empowered'. Human rights education fosters the development of occupational therapists who are skilled, knowledgeable, confident and empowered to address occupational injustices, according to these research findings. To develop a more occupationally just global society, education that considers iniquitous social structures and human rights is necessary. © 2016 Occupational Therapy Australia.

    We describe the automated spectral classification, redshift determination, and parameter measurement pipeline in use for the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey III (SDSS-III) as of the survey's ninth data release (DR9), encompassing 831,000 moderate-resolution optical spectra. We give a review of the algorithms employed, and describe the changes to the pipeline that have been implemented for BOSS relative to previous SDSS-I/II versions, including new sets of stellar, galaxy, and quasar redshift templates. For the color-selected "CMASS" sample of massive galaxies at redshift 0.4 visual inspections of a subset of BOSS galaxies, we find that approximately 0.2% of confidently reported CMASS sample classifications and redshifts are incorrect, and about 0.4% of all CMASS spectra are objects unclassified by the current algorithm which are potentially recoverable. The BOSS pipeline confirms that ~51.5% of the quasar targets have quasar spectra, with the balance mainly consisting of stars and low signal-to-noise spectra. Statistical (as opposed to systematic) redshift errors propagated from photon noise are typically a few tens of km s-1 for both galaxies and quasars, with a significant tail to a few hundreds of km s-1 for quasars. We test the accuracy of these statistical redshift error estimates using repeat observations, finding them underestimated by a factor of 1.19-1.34 for galaxies and by a factor of two for quasars. We assess the impact of sky-subtraction quality, signal-to-noise ratio, and other factors on galaxy redshift success. Finally, we document known issues with the BOSS DR9 spectroscopic data set and describe directions of ongoing development.

  15. The Effect of Answering in a Preferred Versus a Non-Preferred Survey Mode on Measurement

    2014-12-01

    Full Text Available Previous research has shown that offering respondents their preferred mode can increase response rates, but the effect of doing so on how respondents process and answer survey questions (i.e., measurement is unclear. In this paper, we evaluate whether changes in question format have different effects on data quality for those responding in their preferred mode than for those responding in a non-preferred mode for three question types (multiple answer, open-ended, and grid. Respondents were asked about their preferred mode in a 2008 survey and were recontacted in 2009. In the recontact survey, respondents were randomly assigned to one of two modes such that some responded in their preferred mode and others did not. They were also randomly assigned to one of two questionnaire forms in which the format of individual questions was varied. On the multiple answer and open-ended items, those who answered in a non-preferred mode seemed to take advantage of opportunities to satisfice when the question format allowed or encouraged it (e.g., selecting fewer items in the check-all than the forced-choice format and being more likely to skip the open-ended item when it had a larger answer box, while those who answered in a preferred mode did not. There was no difference on a grid formatted item across those who did and did not respond by their preferred mode, but results indicate that a fully labeled grid reduced item missing rates vis-à-vis a grid with only column heading labels. Results provide insight into the effect of tailoring to mode preference on commonly used questionnaire design features.

    The Sloan Digital Sky Survey (SDSS) surveyed 14,555 deg{sup 2}, and delivered over a trillion pixels of imaging data. We present a study of galaxy clustering using 900,000 luminous galaxies with photometric redshifts, spanning between z = 0.45 and z = 0.65, constructed from the SDSS using methods described in Ross et al. This data set spans 11,000 deg{sup 2} and probes a volume of 3 h {sup -3} Gpc{sup 3}, making it the largest volume ever used for galaxy clustering measurements. We describe in detail the construction of the survey window function and various systematics affecting our measurement. With such a large volume, high-precision cosmological constraints can be obtained given careful control and understanding of the observational systematics. We present a novel treatment of the observational systematics and its applications to the clustering signals from the data set. In this paper, we measure the angular clustering using an optimal quadratic estimator at four redshift slices with an accuracy of {approx}15%, with a bin size of {delta}{sub l} = 10 on scales of the baryon acoustic oscillations (BAOs; at l {approx} 40-400). We also apply corrections to the power spectra due to systematics and derive cosmological constraints using the full shape of the power spectra. For a flat {Lambda}CDM model, when combined with cosmic microwave background Wilkinson Microwave Anisotropy Probe 7 (WMAP7) and H{sub 0} constraints from using 600 Cepheids observed by Wide Field Camera 3 (WFC3; HST), we find {Omega}{sub {Lambda}} = 0.73 {+-} 0.019 and H{sub 0} to be 70.5 {+-} 1.6 s{sup -1} Mpc{sup -1} km. For an open {Lambda}CDM model, when combined with WMAP7 + HST, we find {Omega}{sub K} = 0.0035 {+-} 0.0054, improved over WMAP7+HST alone by 40%. For a wCDM model, when combined with WMAP7+HST+SN, we find w = -1.071 {+-} 0.078, and H{sub 0} to be 71.3 {+-} 1.7 s{sup -1} Mpc{sup -1} km, which is competitive with the latest large-scale structure constraints from large spectroscopic

    Course-based undergraduate research experiences (CUREs) are increasingly being offered as scalable ways to involve undergraduates in research. Yet few if any design features that make CUREs effective have been identified. We developed a 17-item survey instrument, the Laboratory Course Assessment Survey (LCAS), that measures students' perceptions of three design features of biology lab courses: 1) collaboration, 2) discovery and relevance, and 3) iteration. We assessed the psychometric properties of the LCAS using established methods for instrument design and validation. We also assessed the ability of the LCAS to differentiate between CUREs and traditional laboratory courses, and found that the discovery and relevance and iteration scales differentiated between these groups. Our results indicate that the LCAS is suited for characterizing and comparing undergraduate biology lab courses and should be useful for determining the relative importance of the three design features for achieving student outcomes. © 2015 L.

  19. Measuring social exclusion in routine public health surveys: construction of a multidimensional instrument.

    Directory of Open Access Journals (Sweden)

    Addi P L van Bergen

    Full Text Available INTRODUCTION: Social exclusion is considered a major factor in the causation and maintenance of health inequalities, but its measurement in health research is still in its infancy. In the Netherlands the Institute for Social Research (SCP developed an instrument to measure the multidimensional concept of social exclusion in social and economic policy research. Here, we present a method to construct a similar measure of social exclusion using available data from public health surveys. METHODS: Analyses were performed on data from the health questionnaires that were completed by 20,877 adults in the four largest cities in the Netherlands. From each of the four questionnaires we selected the items that corresponded to those of the SCP-instrument. These were entered into a nonlinear canonical correlation analysis. The measurement properties of the resulting indices and dimension scales were assessed and compared to the SCP-instrument. RESULTS: The internal consistency of the indices and most of the dimension scales were adequate and the internal structure of the indices was as expected. Both generalisabiliy and construct validity were good: in all datasets strong associations were found between the index and a number of known risk factors of social exclusion. A limitation of content validity was that the dimension "lack of normative integration" could not be measured, because no relevant items were available. CONCLUSIONS: Our findings indicate that a measure for social exclusion can be constructed with available health questionnaires. This provides opportunities for application in public health surveillance systems in the Netherlands and elsewhere in the world.

    The author uses data from the 1991 Current Population Survey and the fourth edition of the Dictionary of Occupational Titles to examine the extent to which U.S. labor markets are segmented across occupational as well as industrial divisions. Consideration is also given to the differences between the male and the female work force in this regard. The author uses differences in educational status to identify distinct wage regimes across occupations. The implications both for the market structure as a whole and for gender inequalities are assessed.

  1. Measuring the Impact of Active Learning in a Redesigned Large-enrollment Introductory Geoscience Survey Course

    Over the past two years, faculty in the UA Geosciences engaged in a major course redesign effort with the goal of improving student learning and attitudes while, at the same time, dramatically reducing costs of offering such a course. The course serves as an undergraduate general education science requirement. Using a reformed teaching framework of learner-centered education, the large-enrollment, introductory geosciences survey course was overhauled to include interactive lectures, just-in-time online quizzes, a next- generation textbook, and weekly discussions lead by graduate students and undergraduate peer mentors. The Geosciences Concept Inventory (GCI) was given as a pre-test/post-test to students in the pre-modified course and the reformed course to compare student learning in terms of gain scores. Although the entire 78-items were administered, divided into three forms, only the 36-items that most directly related to course content were used for analysis. Students in the unmodified course had a pre-test GCI percentage correct of 28.67 (SD=11.45, n=96) which increased to 45.26 (SD=11.76, n=84) on the post-test. After course redesign, students had a pre-test GCI percentage correct of 38.62 (SD=8.42, n=144) which increased a post-test GCI score of 48.73 (SD=7.49, n=132). Although the gains from pre-test to post-test are statistically significant, the different in post-test GCI scores between the two groups is not. This is interpreted as students' knowledge levels, insofar as the GCI can measure, were equivalent in both courses. The Likert-style Attitudes Toward Science Survey was given as an end-of-class post-test to students in the pre-modified course and as a pre-test post-test the reformed course to compare student attitudes between the courses. The average ranking on a 5-point scale as a pre-test was 3.454 (SD=1.259, n=508) whereas the post-tests for the unmodified course was 3.49 (SD=1.05, n=101) and 3.50 (SD=1.127, n=369) for the reformed course.

    With warmer weather projections, workplace heat exposure is presenting a growing challenge to workers' health and safety. Occupational hygienists are the specialist group conducting measurements and providing advice on heat stress management to industry. In order to provide insights into hygienists perceptions on workplace heat exposure, current and future preparedness for extreme heat, and barriers to possible heat adaptation strategies, a self-administered questionnaire survey was conducted during a national conference of the Australian Institute of Occupational Hygienists. Nearly 90% of the 180 respondents were at least moderately concerned about extreme heat and 19% were dissatisfied with current heat stress prevention measures. Barriers recognized by the participants were lack of awareness (68%), insufficient training (56%), unsatisfactory management commitment (52%), and low compliance with prevention policies (40%). The findings suggest a need to refine occupational heat management and prevention strategies.

    Full Text Available Modern society demands cheap, more efficient, and safer public transport. These enhancements, especially an increase in efficiency and safety, are accompanied by huge amounts of data traffic that need to be handled by wireless communication systems. Hence, wireless communications inside and outside trains are key technologies to achieve these efficiency and safety goals for railway operators in a cost-efficient manner. This paper briefly describes nowadays used wireless technologies in the railway domain and points out possible directions for future wireless systems. Channel measurements and models for wireless propagation are surveyed and their suitability in railway environments is investigated. Identified gaps are pointed out and solutions to fill those gaps for wireless communication links in railway environments are proposed.

    2010-01-01

    Occupational exposures cause 10-15% of new-onset asthma in adults, and that represents a considerable health and economic burden. Exposure to many causative agents is now well controlled but workplace practices are constantly evolving and new hazards being introduced. Overall, there is no good evidence that the incidence of occupational asthma is decreasing. Evidence-based guidelines such as those published by the British Occupational Health research Foundation and Standards of Care documents should help raise awareness of the problem and improve management. Key targets include the control of occupational exposures, a high index of suspicion in any adult with new onset asthma, and early detailed investigation.

    Full Text Available AbstractAs explained by the World Health Organisation (WHO in 2000, the concept of health system responsiveness is one of the core goals of health systems. Since 2000, further efforts have been made to measure health system responsiveness and the factors affecting responsiveness, yet few studies have applied responsiveness concepts to the evaluation of mental health systems. The present study aims to measure responsiveness and its related domains in the mental health care system of Tehran. Utilising the same method used by the WHO for its responsiveness survey, responsiveness for outpatient mental health care was evaluated using a validated Farsi questionnaire. A sample of 500 public mental health service users in Tehran participated and subsequently completed the questionnaire. On average, 47% of participants reported experiencing poor responsiveness. Among responsiveness domains, confidentiality and dignity were the best performing factors while autonomy, access to care and quality of basic amenities were the worst performing. Respondents who reported their social status as low were more likely to experience poor responsiveness overall. Autonomy, quality of basic amenities and clear communication were responsiveness dimensions that performed poorly but were considered to be important by study participants. In summary, the study suggests that measuring responsiveness could provide guidance for further development of mental health care systems to become more patient orientated and provide patients with more respect.

    The state of California is leading the United States by enacting legislation (AB-32) to reduce greenhouse gas emissions to 1990 levels by 2020. The success of reduction efforts can be gauged with accurate emissions inventories and potentially verified with atmospheric measurements of greenhouse gases (GHGs) over time. Measurements of multiple GHGs and associated trace gas species in a specific region also provide information on emissions ratios for source apportionment. We conducted the Airborne Greenhouse Emissions Survey (AGES) campaign to determine emissions signature ratios for the sources that exist in the San Francisco Bay and Sacramento Valley areas. Specifically, we attempt to determine the emissions signatures of sources that influence ongoing measurements made at a tall-tower measurement site near Walnut Grove, CA. For two weeks in February and March of 2009, a Cessna 210 was flown throughout the Sacramento region, making continuous measurements of CO2, CH4, and CO while also sampling discrete flasks for a variety of additional tracers, including SF6, N2O, and 14C in CO2 (Δ14CO2). Flight paths were planned using wind predictions for each day to maximize sampling of sources whose emissions would also be sampled contemporaneously by the instrumentation at the Walnut Grove tower (WGC), part of the ongoing California Greenhouse Gas Emissions Measurement (CALGEM) project between NOAA/ESRL’s Carbon Cycle group and Lawrence Berkeley National Laboratory (LBNL). Flights were performed in two distinct patterns: 1) flying across a plume upwind and downwind of the Sacramento urban area, and 2) flying across the Sacramento-San Joaquin Delta from Richmond to Walnut Grove, a region consisting of natural wetlands as well as several power plants and refineries. Results show a variety of well-correlated mixing ratio signals downwind of Sacramento, documenting the urban signature emission ratios, while emissions ratios in the Delta region were more variable, likely due

    We compare cosmic microwave background lensing convergence maps derived from South Pole Telescope (SPT) data with galaxy survey data from the Blanco Cosmology Survey, the Wide-field Infrared Survey Explorer, and a new large Spitzer/IRAC field designed to overlap with the SPT survey. Using optical and infrared catalogs covering between 17 and 68 square degrees of sky, we detect correlation between the SPT convergence maps and each of the galaxy density maps at >4 sigma, with zero cross-correlation robustly ruled out in all cases. The amplitude and shape of the cross-power spectra are in good agreement with theoretical expectations and the measured galaxy bias is consistent with previous work. The detections reported here utilize a small fraction of the full 2500 square degree SPT survey data and serve as both a proof of principle of the technique and an illustration of the potential of this emerging cosmological probe.

  14. How social processes distort measurement: the impact of survey nonresponse on estimates of volunteer work in the United States.

    Science.gov (United States)

    Abraham, Katharine G; Presser, Stanley; Helms, Sara

    2009-01-01

    The authors argue that both the large variability in survey estimates of volunteering and the fact that survey estimates do not show the secular decline common to other social capital measures are caused by the greater propensity of those who do volunteer work to respond to surveys. Analyses of the American Time Use Survey (ATUS)--the sample for which is drawn from the Current Population Survey (CPS)--together with the CPS volunteering supplement show that CPS respondents who become ATUS respondents report much more volunteering in the CPS than those who become ATUS nonrespondents. This difference is replicated within subgroups. Consequently, conventional adjustments for nonresponse cannot correct the bias. Although nonresponse leads to estimates of volunteer activity that are too high, it generally does not affect inferences about the characteristics of volunteers.

    Using daylight as primary light source has been widely recognized as an important strategy to reduce building energy demand and enhance indoor environment quality. However, to design and operate a building to make full use of daylight, which is a dynamic light source, to meet diverse occupant needs remains a challenge. This paper reports a post-occupancy study of the visual environment in a laboratory building on a university campus, and puts a spotlight on the building occupants as it examines the effectiveness of the daylighting design and systems integration in creating a visual environment to support occupant comfort and satisfaction while reducing artificial lighting demand. Results show generally high satisfaction with daylit work environment and positive effect of the horizontal shading strategy. Issues about the integration between daylighting and electric lighting systems and level of occupant control are identified and discussed for improving the effectiveness of daylighting and enhancing the quality of the visual environment in the building of study. A multiple-tool methodology is developed and tested, which included occupant surveys, interviews, illuminance measurements, continuous data loggers, fisheye-lens camera and glare-identifying software, and documentation of spatial settings, systems features, and user behavior.

  19. A Gibbs sampler for Bayesian analysis of site-occupancy data

    Dorazio, Robert M.; Rodriguez, Daniel Taylor

    2012-01-01

    1. A Bayesian analysis of site-occupancy data containing covariates of species occurrence and species detection probabilities is usually completed using Markov chain Monte Carlo methods in conjunction with software programs that can implement those methods for any statistical model, not just site-occupancy models. Although these software programs are quite flexible, considerable experience is often required to specify a model and to initialize the Markov chain so that summaries of the posterior distribution can be estimated efficiently and accurately. 2. As an alternative to these programs, we develop a Gibbs sampler for Bayesian analysis of site-occupancy data that include covariates of species occurrence and species detection probabilities. This Gibbs sampler is based on a class of site-occupancy models in which probabilities of species occurrence and detection are specified as probit-regression functions of site- and survey-specific covariate measurements. 3. To illustrate the Gibbs sampler, we analyse site-occupancy data of the blue hawker, Aeshna cyanea (Odonata, Aeshnidae), a common dragonfly species in Switzerland. Our analysis includes a comparison of results based on Bayesian and classical (non-Bayesian) methods of inference. We also provide code (based on the R software program) for conducting Bayesian and classical analyses of site-occupancy data.
