Activities of the Shielding Subcommittee of the ENDF/B Cross Section Evaluation Working Group

International Nuclear Information System (INIS)

Roussin, R.W.

1977-01-01

The Shielding Subcommittee of the Cross Section Evaluation Working Group (CSEWG) was established in 1967 to help ensure that the content of the ENDF/B cross section library was adequate for treating shielding problems. Early work of the subcommittee concentrated on devising formats for gamma-ray interaction and production data, as well as providing programs for testing the clerical and physics consistency of the files. The Radiation Shielding Information Center (RSIC) collaborated directly with evaluators on behalf of the National Neutron Cross Section Center (NNCSC) to begin testing and adding data sets to be fed into the official ENDF/B libraries. These efforts, which were sponsored by AEC-DRDT (now ERDA-DRDD), were augmented greatly through the Defense Nuclear Agency program of establishing a working cross section library in ENDF format. The effort concentrated on evaluation and testing of materials of interest to DNA programs and providing these for inclusion in the ENDF/B library. Shielding data testing efforts, as a part of the CSEWG Data Testing Program, are now also an integral part of the Shielding Subcommittee effort. Procedures for writing and approving the shielding benchmarks were devised by Shielding Subcommittee members. Data testing benchmark experiments have been documented and analyzed, and the most recent results for ENDF/B-IV are as reported as part of ENDF-230, ''Benchmark Testing of ENDF/B-IV.''

The Cross Section Evaluation Working Group is a long-standing committee charged with the responsibility for organizing and overseeing the U.S. cross-section evaluation effort. It's main product is the official U.S. evaluated nuclear data file, ENDF; the current version of this file is Version VI. All evaluations included in ENDF are reviewed and approved by CSEWG and issued by the U.S. Nuclear Data Center, Brookhaven National Laboratory. CSEWG is comprised of volunteers from the U.S. nuclear data community who possess expertise in evaluation methodologies and who collectively have been responsible for producing most of the evaluations included in ENDF. In 1992 CSEWG added the Measurements Committee to its list of standing committees and subcommittees. This was based on recognition of the importance of experimental data in the evaluation process as well as the realization that measurement activities in the U.S. were declining at an alarming rate. The mission of the Committee is to establish a network of experimentalists in the U.S. which would provide encouragement to the national nuclear data measurement effort through improved communication and facilitation of collaborative activities. The Committee currently has 19 members, and interested scientists are welcome to join the network simply by contacting the Chairman. For reference, the names of the current members and contact information are contained in this report. This annual report is the first such document issued by the Committee. It contains voluntary contributions from 10 laboratories in the U.S. which have been prepared by members of the Committee and submitted to the Chairman for compilation and editing. This report is being distributed in hard copy and is also available on-line via the National Nuclear Data Center, Brookhaven National Laboratory.

Mechanized evaluation of neutron cross-sections

International Nuclear Information System (INIS)

Horsley, A.; Parker, J.B.

1967-01-01

The evaluation work to provide accurate and consistent neutron cross-section data for multigroup neutronics calculations is not fully exploiting the available theoretical and experimental results; this has been so particularly since the introduction of on-line data handling techniques enabled experimenters to turn out vast quantities of numbers. This situation can be radically improved only by mechanizing the evaluation processes. Systems such as the SC1SRS tape will not only largely overcome the task of collecting data but will provide speedy access to it; by using computers and graph-plotting machines to tabulate and display this data, the labour of evaluation can be very greatly reduced. With some types of cross-section there is hope that by using modern curve-fitting techniques the actual evaluation and statistical accounting of the data can be performed automatically. Some areas where automatic evaluation would seem likely to succeed are specified and a discussion of the mathematical difficulties incurred, such as the elimination of anomalous data, is given. Particularly promising is the use of splines in the mechanized evaluation of data. Splines are the mathematical analogues of the draughtsman's spline used in drawing smooth curves. Their principal properties are the excellent approximations they give to the derivatives of a function; in contrast to conventional polynomial fitting, this feature ensures good interpolation and, when required, stable extrapolation. Various methods of using splines in data graduation and the problem of marrying these methods to standard statistical procedures are examined. The results of work done at AWRE with cubic splines on the mechanized evaluation of neutron scattering total cross-section and angular distribution data are presented. (author)

Evaluation of fission product neutron cross sections for JENDL

International Nuclear Information System (INIS)

1984-01-01

The recent activities on the evaluation of fission product (FP) neutron cross sections for JENDL (Japanese Evaluated Nuclear Data Library) are presented briefly. The integral test of JENDL-1 FP cross section file was performed using the CFRMF sample activation data and the STEK sample reactivity data, and the ratio of experiment to calculation was nearly constant for all the samples in the STEK measurement. Therefore, a tentative analysis was performed by applying the correction to the calculated scattering reactivity component. Better agreement with the experiment was obtained after applying this correction in most cases. The evaluation work on the JENDL-2 FP neutron cross sections is now in progress. The improvement of the data evaluation is presented in an itemized form. The JENDL-2 FP file will contain the evaluated data for 100 nuclides from Kr to Tb. The improvement and the future scope of the integral test for JENDL-2 FP data are summarized. (Asami, T.)
Cutting work in thick section cryomicrotomy.

Saubermann, A J; Riley, W D; Beeuwkes, R

1977-09-01

The forces during cryosectioning were measured using miniature strain gauges attached to a load cell fitted to the drive arm of the Porter-Blum MT-2 cryomicrotome. Work was calculated and the data normalized to a standard (1 mm X 1 mm X 0.5 micrometer) section. Thermal energy generated was also calculated. Five parameters were studied: cutting angle, thickness, temperature, hardness, and block shape. Force patterns could be divided into three major groups thought to represent cutting (Type I), large fracture planes greater than 10 micrometer in length (Type II), and small fracture planes less than 10 micrometer in length (Type III). Type I and Type II produced satisfactory sections. Work in cutting ranged from an average of 78.4 muJ to 568.8 muJ. Cutting angle and temperature had the greatest effect on sectioning. Heat generated would be sufficient to cause through-section melting for 0.5 micrometer thick sections assuming the worst possible case, namely that all heat went into the section without loss. Presence of a Type II pattern (large fracture pattern) is thought to be presumptive evidence against thawing.

Organ transplantation has increased in Italy over the last decade. Thus, an increasing number of workers may face the problem of returning to work. The aim of this study was to provide an assessment of working ability of transplant recipients in comparison with their actual employment status. This study was based on 150 patients who underwent transplantation since 1994 and who underwent periodic post-transplantation examination during 2012. Fifty patients who had undergone heart transplantation (HT), 50 liver transplantation (LT), and 50 kidney transplantation (KT) and survived at least 12 months after surgery were eligible for this study. All patients underwent the International Classification of Functioning, Disabilities and Health (ICF) questionnaire; ten questions were further applied to those who were employed at the time of the study. X(2) statistics were used to compare working ability evaluation and employment status and for internal comparison among different organ recipients. The employment status was as follows: 92 (61%) patients were in paid employment, 6 (4%) were students or housewives, 36 (24%) were unemployed, and 17 (11%) were retired because of invalidity benefits. According to our fitness evaluation only 4% to 10% of the patients were unfit for any job. When we excluded retired subjects, the X(2) statistics for correlated observations showed a highly significant statistical difference (P working ability evaluation by ICF questionnaire and other questions. This may be due to several factors including health status and the possibility of gaining an adequate job. The ICF questionnaire proved to be a useful framework that can be used for research but also by occupational physicians in their usual practice after specific training. Copyright © 2014 Elsevier Inc.

Contribution to uncertainties evaluation for fast reactors neutronic cross sections

Privas, Edwin

2015-01-01

The thesis has been motivated by a wish to increase the uncertainty knowledge on nuclear data, for safety criteria. It aims the cross sections required by core calculation for sodium fast reactors (SFR), and new tools to evaluate its.The main objective of this work is to provide new tools in order to create coherent evaluated files, with reliable and mastered uncertainties. To answer those problematic, several methods have been implemented within the CONRAD code, which is developed at CEA of Cadarache. After a summary of all the elements required to understand the evaluation world, stochastic methods are presented in order to solve the Bayesian inference. They give the evaluator more information about probability density and they also can be used as validation tools. The algorithms have been successfully tested, despite long calculation time. Then, microscopic constraints have been implemented in CONRAD. They are defined as new information that should be taken into account during the evaluation process. An algorithm has been developed in order to solve, for example, continuity issues between two energy domains, with the Lagrange multiplier formalism. Another method is given by using a marginalization procedure, in order to either complete an existing evaluation with new covariance or add systematic uncertainty on an experiment described by two theories. The algorithms are well performed along examples, such the 238 U total cross section. The last parts focus on the integral data feedback, using methods of integral data assimilation to reduce the uncertainties on cross sections. This work ends with uncertainty reduction on key nuclear reactions, such the capture and fission cross sections of 238 U and 239 Pu, thanks to PROFIL and PROFIL-2 experiments in Phenix and the Jezebel benchmark.

1998-03-01

In order to generate photonuclear cross section library for the necessary applications, data evaluation is combined with theoretical evaluation, since photonuclear cross sections measured cannot provide all necessary data. This report recommends a procedure consisting of four steps: (1) analysis of experimental data, (2) data evaluation, (3) theoretical evaluation and, if necessary, (4) modification of results. In the stage of analysis, data obtained by different measurements are reprocessed through the analysis of their discrepancies to a representative data set. In the data evaluation, photonuclear absorption cross sections are evaluated via giant dipole resonance and quasi-deutron mechanism. With photoabsorption cross sections from the data evaluation, theoretical evaluation is applied to determine various decay channel cross sections and emission spectra using equilibrium and preequilibrium mechanism. After this, the calculated results are compared with measured data, and in some cases the results are modified to better describe measurements. (author)

Badikov, S.; Golashvili, T.

2008-01-01

Some steps of the validation and verification of the new version of the evaluated neutron standard cross sections were carried out. In particular: -) the evaluated covariance data was checked for physical consistency, -) energy-dependent evaluated cross-sections were tested in most important neutron benchmark field - 252 Cf spontaneous fission neutron field, -) a procedure of folding differential standard neutron data in group representation for preparation of specialized libraries of the neutron standards was verified. The results of the validation and verification of the neutron standards can be summarized as follows: a) the covariance data of the evaluated neutron standards is physically consistent since all the covariance matrices of the evaluated cross sections are positive definite, b) the 252 Cf spectrum averaged standard cross-sections are in agreement with the evaluated integral data (except for 197 Au(n,γ) reaction), c) a procedure of folding differential standard neutron data in group representation was tested, as a result a specialized library of neutron standards in the ABBN 28-group structure was prepared for use in reactor applications.

Neutron-induced reactions between 0 eV and 20 MeV are based on various physical properties such as nuclear reaction models, microscopic and integral measurements. Most of the time, the evaluation work is done independently between the resolved resonance range and the continuum, giving rise to mismatches for the cross-sections, larger uncertainties on boundary and no cross-correlation between high-energy domain and resonance range. In addition the use of integral experiment is sometimes only related to central values (evaluation is 'working fine' on a dedicated set of benchmarks) and reductions of uncertainties are not straightforward on cross-sections themselves: working fine could be mathematically reflected by a reduced uncertainty. As the CIELO initiative is to bring experts in each field to propose/discuss these matters, after having presented the status of 238 U and 239 Pu cross-sections covariances evaluation (for JEFF-3.2 as well as the WPEC SG34 subgroup), this paper will present several methodologies that may be used to avoid such effects on covariances. A first idea based on the use of experiments overlapping two energy domains appeared in the near past. It was reviewed and extended to the use of systematic uncertainties (normalisation for example) and for integral experiments as well. In addition, we propose a methodology taking into account physical constraints on an overlapping energy domain where both nuclear reaction models are used (continuity of both cross-sections and derivatives for example). The use of Lagrange multiplier (related to these constraints) in a classical generalised least square procedure will be exposed. Some academic examples will then be presented for both point-wise and multi-group cross-sections to present the methodologies. In addition, new results for 239 Pu will be presented on resonance range and higher energies to reduce capture and fission cross-section uncertainties by using integral experiments (JEZEBEL experiment as

Besides, new evaluations were performed for four additional dosimetry reactions, namely 52 Cr(n,2n) 51 Cr, 59 Co(n,2n) 58 Co, 93 Nb(n,2n) 92m Nb and 197 Au(n,2n) 196 Au. The deadlines for the retrieval of data for the different reactions lay between March 1989 and February 1990. The evaluations comprise the neutron energy range from threshold to 20 MeV, in a few cases this range is extended up to 21 MeV or 30 MeV. Cross sections and their uncertainties were evaluated in energy groups with widths of 0.1 MeV to 2.0 MeV, and relative correlation matrices of the evaluated cross sections at different energies were derived. The results of the evaluations are compared to the previous ones and to other recent evaluations reported in the literature. The main results of our previous evaluations for the reactiosn 19 F(n,2n) 18 F, 31 P(n,p) 31 Si, 63 Cu(n,2n) 62 Cu and 103 Rh(n,n') 103m Rh which remain unchanged are also given for completeness.

Faced with the challenge of population aging, a prolonged working life is increasingly important in today's society. Maintaining work ability of employees is one of the effective ways to cope with the challenges to sustainability of the workforce presented by population aging. Researchers have shown ongoing interest in exploring the determinants of restricted work ability. The aim of this study was to evaluate the effects of work stress on work ability among power supply workers in Guangdong, China. A cross-sectional study was conducted among power supply workers during August 2014 to September 2014. A total of 805 subjects were enrolled in the study. Work stress was assessed by the Job Content Questionnaire and the Effort Reward Imbalance Questionnaire. Work ability was assessed by the Work Ability Index (WAI). The structural equation model was applied to test the relationship between different work stress components and work ability simultaneously using the Job Demands-Resources model as a framework. Job resources (measured by job control, reward and social support) were positively and directly associated with work ability (β = 0.70, P work ability was also statistically significant (β = -0.09, P = 0.030). In addition, the findings also supported previous studies in that job demands were correlated with job resources (β = -0.26, P work ability.
ENDF/B-5 fission product cross section evaluations

Schenter, R.E.; England, T.R.

1979-12-01

Cross section evaluations were made for the 196 fission product nuclides on the ENDF/B-5 data files. Most of the evaluations involve updating the capture cross sections of the important absorbers for fast and thermal reactor systems. This included updating thermal values, resonance integrals, resonance parameter sets, and fast capture cross sections. For the fast capture results generalized least-squares calculations were made with the computer code FERRET. Input for these cross section adjustments included nuclear models calculations and both integral and differential experimental data results. The differential cross sections and their uncertainties were obtained from the CSIRS library. Integral measurement results came from CFRMF and STEK Assemblies 500, 1000, 2000, 3000, 4000. Comparisons of these evaluations with recent capture measurements are shown. 15 figures, 10 tables

Presently, several methods are used to estimate the covariance matrix of evaluated nuclear cross sections. Because the resulting covariance matrices can be different according to the method used and according to the assumptions of the method, we propose a general and objective approach to quantify the quality of the covariance estimation for evaluated cross sections. The first step consists in defining an objective criterion. The second step is computation of the criterion. In this paper the Kullback-Leibler distance is proposed for the quality quantification of a covariance matrix estimation and its inverse. It is based on the distance to the true covariance matrix. A method based on the bootstrap is presented for the estimation of this criterion, which can be applied with most methods for covariance matrix estimation and without the knowledge of the true covariance matrix. The full approach is illustrated on the 85 Rb nucleus evaluations and the results are then used for a discussion on scoring and Monte Carlo approaches for covariance matrix estimation of the cross section evaluations

This Report summarizes the results of the activities in 2012 and the first half of 2013 of the LHC Higgs Cross Section Working Group. The main goal of the working group was to present the state of the art of Higgs Physics at the LHC, integrating all new results that have appeared in the last few years. This report follows the first working group report Handbook of LHC Higgs Cross Sections: 1. Inclusive Observables (CERN-2011-002) and the second working group report Handbook of LHC Higgs Cross Sections: 2. Differential Distributions (CERN-2012-002). After the discovery of a Higgs boson at the LHC in mid-2012 this report focuses on refined prediction of Standard Model (SM) Higgs phenomenology around the experimentally observed value of 125-126 GeV, refined predictions for heavy SM-like Higgs bosons as well as predictions in the Minimal Supersymmetric Standard Model and first steps to go beyond these models. The other main focus is on the extraction of the characteristics and properties of the newly discovered p...

To explore the separate and combined effects of work and family stress on menstrual disorders and fibrocystic changes in Chinese working women. Data were obtained from a cross-sectional study of 1,642 female railway workers. The Effort-Reward Imbalance Questionnaire and Family Stress Scale were used to measure work stress and family stress, respectively; the menstrual and breast conditions were evaluated by gynecologic interview and a medical examination. Multivariate log-binomial regression was performed to analyze the associations. Menstrual disorders were found in 59.3% of female workers, and 54.8% had fibrocystic changes. The risk of menstrual disorders was significantly elevated with respect to work and family stress. The highest risk was found in the group with combined exposure to both work and family stress (RR with 95% CI 1.33 (1.18-1.49)). No significant association between stress and fibrocystic changes was observed. Menstrual disorders were associated with stress from work and family life, but not fibrocystic changes, in working women. Tailored intervention measures reducing the burden of stressful psychosocial work and family environment are needed to improve women's reproductive well-being.

A Working Party on International Evaluation Co-operation was established under the sponsorship of the OECD/NEA Nuclear Science Committee (NSC) to promote the exchange of information on nuclear data evaluations, validation, and related topics. Its aim is also to provide a framework for co-operative activities between members of the major nuclear data evaluation projects. This includes the possible exchange of scientists in order to encourage co-operation. Requirements for experimental data resulting from this activity are compiled. The Working Party determines common criteria for evaluated nuclear data files with a view to assessing and improving the quality and completeness of evaluated data. The Parties to the project are: ENDF (United States), JEFF/EFF (NEA Data Bank Member countries), and JENDL (Japan). Co-operation with evaluation projects of non-OECD countries are organised through the Nuclear Data Section of the International Atomic Energy Agency (IAEA). NEA/NSC Subgroup 15 has had the task to assess self-shielding effects in the unresolved resonance range of structural materials, in particular their importance at various energies, and possible ways to deal with them in shielding and activation work. The principal results achieved are summarised briefly, in particular: - New data base consisting of high-resolution transmission data measured at Oak Ridge and Geel; - Improved theoretical understanding of cross-section fluctuations, including their prediction, that has been derived from the Hauser-Feshbach theory; - Benchmark results on the importance of self-shielding in iron at various energies; - Consequences for information storage in evaluated nuclear data files; - Practical utilisation of self-shielding information from evaluated files. Benchmark results as well as the Hauser-Feshbach theory show that self-shielding effects are important up to a 4-or 5-MeV neutron energy. Fluctuation factors extracted from high-resolution total cross-section data can be
Unpaid work in health economic evaluations.

Given its societal importance, unpaid work should be included in economic evaluations of health care technology aiming to take a societal perspective. However, in practice this does not often appear to be the case. This paper provides an overview of the current place of unpaid work in economic evaluations in theory and in practice. It does so first by summarizing recommendations regarding the inclusion of unpaid labor reported in health economic textbooks and national guidelines for economic evaluations. In total, three prominent health economic text-books were studied and 28 national health economic guidelines. The paper, moreover, provides an overview of the instruments available to measure lost unpaid labor and reports on a review of the place of unpaid labor in applied economic evaluations in the area of rheumatoid arthritis. The review was conducted by examining methodology of evaluations published between 1 March 2008 and 1 March 2013. The results of this study show that little guidance is offered regarding the inclusion of unpaid labor in economic evaluations in textbooks and guidelines. The review identified five productivity costs instruments including questions about unpaid work and 33 economic evaluations of treatments for rheumatoid arthritis of which only one included unpaid work. The results indicate that unpaid work is rarely included in applied economic evaluations of treatments for rheumatoid arthritis, despite this disease expecting to be associated with lost unpaid work. Given the strong effects of certain diseases and treatments on the ability to perform unpaid work, unpaid work currently receives less attention in economic evaluations than it deserves.

This publication has been prepared to record some of the history of the Cross Section Evaluation Working Group (CSEWG). CSEWG is responsible for creating the evaluated nuclear data file (ENDF/B) which is widely used by scientists and engineers who are involved in the development and maintenance of applied nuclear technologies. This organization has become the model for the development of nuclear data libraries throughout the world. The data format (ENDF) has been adopted as the international standard. On November 5, 2001, a symposium was held at Brookhaven National Laboratory to celebrate the 50 th meeting of the CSEWG organization and the 35 th anniversary of its first meeting in November 1966. The papers presented in this volume were prepared by present and former CSEWG members for presentation at the November 2001 symposium. All but two of the presentations are included. I have included an appendix to list all of the CSEWG members and their affiliations, which has been compiled from the minutes of each of the CSEWG meetings. Minutes exist for all meetings except the 4 th meeting held in January 1968. The list includes 348 individuals from 71 organizations. The dates for each of the 50 CSEWG meetings are listed. The committee structure and chairmen of all committees and subcommittees are also included in the appendix. This volume is dedicated to three individuals whose foresight and talents made CSEWG possible and successful. They are Henry Honeck who lead the effort to develop the ENDF format and the CSEWG system, Ira Zartman, the Atomic Energy Commission program manager who provided the programmatic direction and support, and Sol Pearlstein who led the development of the CESWG organization and the ENDF/B evaluated nuclear data library.

Shift work is associated with negative health effects. Increased prevalence of several cardiovascular risk factors among shift workers/night workers compared with day workers have been shown resulting in increased risk of cardiovascular events among shift workers and night workers. Previous studies have taken a dichotomous approach to the comparison between day and night workers. The present study uses a continuous approach and provides such a new perspective to the negative effects of night work load as a possible risk factor for undesirable health effects. This cross sectional study (The SUrvey of Shift work, Sleep and Health (SUSSH)) uses data collected from December 2008 to March 2009. The study population consists of Norwegian nurses. The study collected information about demographic and lifestyle factors: Body Mass Index (BMI), smoking habits, alcohol consumption, caffeine consumption and exercise habits. The lifestyle parameters were evaluated using multiple hierarchical regression and binary logistic regression. Number of night shifts worked last year (NNL) was used as operationalization of night work load. Adjustment for possible confounders were made. Obesity was defined as BMI > 30. Alcohol Consumption was evaluated using the short form of the Alcohol Use Disorders Identification Test Consumption (AUDIT-C). Data were analyzed using SPSS version 22. We had data from 2059 nurses. NNL was significantly and positively associated with BMI, both when evaluated against BMI as a continuous parameter (Beta = .055, p < .05), and against obesity (OR = 1.01, 95 % CI = 1.00-1.01). The AUDIT-C score was significantly and positively associated with hours worked per week (OR = 1.03, 95 % CI = 1.01-1.05). We found a positive significant association between night work load and BMI. This suggests that workers with a heavy night work load might need special attention and frequent health checks due to higher risk of undesirable health effects.

We present the NNDC-BNL methodology for estimating neutron cross section covariances in thermal, resolved resonance, unresolved resonance and fast neutron regions. The three key elements of the methodology are Atlas of Neutron Resonances, nuclear reaction code EMPIRE, and the Bayesian code implementing Kalman filter concept. The covariance data processing, visualization and distribution capabilities are integral components of the NNDC methodology. We illustrate its application on examples including relatively detailed evaluation of covariances for two individual nuclei and massive production of simple covariance estimates for 307 materials. Certain peculiarities regarding evaluation of covariances for resolved resonances and the consistency between resonance parameter uncertainties and thermal cross section uncertainties are also discussed.

To evaluate the satisfaction with work-life balance (WLB) and career satisfaction of gynecologic oncologists. In August 2014, members of the Society of Gynecologic Oncology (SGO) were sent an anonymous, cross-sectional survey evaluating demographic variables, practice characteristics, career satisfaction, fatigue, and satisfaction with WLB. Fatigue was assessed using a visual-analog scale. Career satisfaction and WLB were assessed with a Likert scale. Inferential statistics were computed with type I error rates of 0.05. Out of the 1002 gynecologic oncologists surveyed, 290 (28.9%) responded. Only 18.6% of respondents were satisfied with WLB and there were significant associations between gender (P = 0.0157), time spent in work related activities at home (P = 0.0024), on weekends (P = 0.0017), and in the hospital (P = 0.0001). More than 84% of physicians reported they would choose medicine as a career again and of those 90% would choose to be a gynecologic oncologist again. Fatigue was strongly associated with dissatisfaction with WLB in univariate and multivariate analysis (P satisfaction may assist the SGO in meeting future gynecologic cancer care needs.

Co-operation with evaluation projects of non-OECD countries are organised through the Nuclear Data Section of the International Atomic Energy Agency (IAEA). The following report was issued by a Subgroup investigating the fission cross-section of Plutonium-239 in the energy range 1 to 100 keV. This cross section is of particular importance for fast reactor applications, such as k eff , sodium void reactivity coefficient and control rod worth. An analysis of recent experimental data by L. Weston et al. give significantly lower cross-section values that the simultaneous evaluation performed by W. Poenitz for the ENDF/B-VI library. The objective of the subgroup was to resolve this discrepancy. One experimental program and one evaluation one have been agreed upon: The experimental program which essentially aims at normalisation checking has been performed in Geel and Oak Ridge. It supports an upward re-normalisation by ∼3.1%. The evaluation program has not been completed and even, as a consequence of the experimental results, loses a part of its justification. But some acquired results are important and can be used for future 239 Pu evaluations. The JEFF-2

Usability evaluation helps to determine whether interactive systems support users in their work tasks. However, knowledge about those tasks and, more generally, about the work-domain is difficult to bring to bear on the processes and outcome of usability evaluation. One way to include such work......-domain knowledge might be Cooperative Usability Testing, an evaluation method that consists of (a) interaction phases, similar to classic usability testing, and (b) interpretation phases, where the test participant and the moderator discuss incidents and experiences from the interaction phases. We have studied...... whether such interpretation phases improve the relevance of usability evaluations in the development of work-domain specific systems. The study included two development cases. We conclude that the interpretation phases generate additional insight and redesign suggestions related to observed usability...

Evaluation of kerma in carbon and the carbon cross sections

International Nuclear Information System (INIS)

Axton, E.J.

1992-02-01

A preliminary simultaneous least squares fit to measurements of kerma in carbon, and carbon cross sections taken from the ENDF/B-V file was carried out. In the calculation the shapes of the total cross section and the various partial cross sections were rigid but their absolute values were allowed to float in the fit within the constraints of the ENDF/B-V uncertainties. The construction of the ENDF/B-V file imposed improbable shapes, particularly in the case of the (12)C(n,n'3(alpha)) reaction, which were incompatible with direct measurements of kerma and of the reaction cross sections. Consequently a new evaluation of the cross section data became necessary. Since the available time was limited the new evaluation concentrated particularly on those aspects of the ENDF/B-V carbon file which would have most impact on kerma calculations. Following the new evaluation of cross sections new tables of kerma factors were produced. Finally, the simultaneous least squares fit to measurements of kerma and the new cross section file was repeated

The data base comprising the results of the 93 Nb(n,n') 93m Nb reactions cross section measurements up to 1991 has been compiled. The experimental data have been renormalized to new values of standard cross-sections from the ENDF/B-6 and the IRDF-90 libraries. The evaluation of excitation function for the 93 Nb(n,n') 93m Nb reaction was carried out on the basis of procedure taking the correlation of experimental data into account. The files of evaluated cross-sections and covariance were prepared in the ENDF/B-6 format. The cross-section evaluations from present work and the IRDF-90 library are compared. 37 refs.; 3 figs.; 6 tabs
Some sources of the underestimation of evaluated cross section uncertainties

International Nuclear Information System (INIS)

Badikov, S.A.; Gai, E.V.

2003-01-01

The problem of the underestimation of evaluated cross-section uncertainties is addressed. Two basic sources of the underestimation of evaluated cross-section uncertainties - a) inconsistency between declared and observable experimental uncertainties and b) inadequacy between applied statistical models and processed experimental data - are considered. Both the sources of the underestimation are mainly a consequence of existence of the uncertainties unrecognized by experimenters. A model of a 'constant shift' is proposed for taking unrecognised experimental uncertainties into account. The model is applied for statistical analysis of the 238 U(n,f)/ 235 U(n,f) reaction cross-section ratio measurements. It is demonstrated that multiplication by sqrt(χ 2 ) as instrument for correction of underestimated evaluated cross-section uncertainties fails in case of correlated measurements. It is shown that arbitrary assignment of uncertainties and correlation in a simple least squares fit of two correlated measurements of unknown mean leads to physically incorrect evaluated results.

Experimental energy-averaged neutron total cross sections of 238 U were evaluated from 0.044 to 20.0 MeV using regorous numerical methods. The evaluated results are presented together with the associated uncertainties and correlation matrix. They indicate that this energy-averaged neutron total cross section is known to better than 1% over wide energy regions. There are somwewhat larger uncertainties at low energies (e.g., less than or equal to 0.2 MeV), near 8 MeV and above 15 MeV. The present evaluation is compard with values given in ENDF/B-V

We present evaluations of the interaction of 20 to 100 MeV neutrons with oxygen and nitrogen nuclei, which follows on from our previous work on carbon. Our aim is to accurately represent integrated cross sections, inclusive emission spectra, and kerma factors, in a data library which can be used in radiation transport calculations. We apply the FKK-GNASH nuclear model code, which includes Hauser-Feshbach, preequilibrium, and direct reaction mechanisms, and use experimental measurements to optimize the calculations. We determine total, elastic, and nonelastic cross sections, angle-energy correlated emission spectra, for light ejectiles with A{<=}4 and gamma-rays, and average energy depositions. Our results for charged-particle emission spectra agree well with the measurements of Subramanian et al.. We compare kerma factors derived from our evaluated cross sections with experimental data, providing an integral benchmarking of our work. The evaluated data libraries are available as electronic files.

Allergic rhinitis (AR) is a highly prevalent allergic disease and also counts among the 10 most frequent reasons for medical consultation. Its impact on quality of life (QoL) and work productivity has been established but comparisons with other diseases are rare in the literature. The aim of this study was to evaluate the impact of AR in health-related QoL (HRQoL) and work productivity in primary care patients, compared with other prevalent diseases such as hypertension, diabetes mellitus (DM) type II, and symptomatic depression. Six hundred sixteen patients were included in a multicenter cross-sectional observational study. A generic HRQoL questionnaire, 36-item Short Form, and a specific questionnaire, "Work Productivity and Activity Impairment" were handed out to measure QoL and work productivity impact of the diseases. To assess clinical severity with a comparable scale between diseases Clinical Global Impression (CGI) had been used. Symptomatic depression was found to produce the greatest impairment on work productivity with a decrease of 59.5%, with significant differences compared with AR, hypertension, and DM type II (p work productivity in a greater magnitude than hypertension and DM type II.
Evaluated 182,183,184,186W Neutron Cross Sections and Covariances in the Resolved Resonance Region

International Nuclear Information System (INIS)

Pigni, Marco T; Leal, Luiz C

2015-01-01

Oak Ridge National Laboratory (ORNL) has recently completed the resonance parameter evaluation of four tungsten isotopes, i.e., 182,183,184,186 W, in the neutron energy range of thermal up to several keV. This nuclear data work was performed with support from the US Nuclear Criticality Safety Program (NCSP) in an effort to provide improved tungsten cross section and covariance data for criticality safety analyses. The evaluation methodology uses the Reich-Moore approximation of the R-matrix formalism of the code SAMMY to fit high-resolution measurements performed in 2010 and 2012 at the Geel linear accelerator facility (GELINA), as well as other experimental data sets on natural tungsten available in the EXFOR library. In the analyzed energy range, this work nearly doubles the resolved resonance region (RRR) present in the latest US nuclear data library ENDF/B-VII.1. In view of the interest in tungsten for distinct types of nuclear applications and the relatively homogeneous distribution of the isotopic tungsten - namely, 182 W(26.5%), 183 W(14.31%), 184 W(30.64%), and 186 W(28.43%) - the completion of these four evaluations represents a significant contribution to the improvement of the ENDF library. This paper presents an overview of the evaluated resonance parameters and related covariances for total and capture cross sections on the four tungsten isotopes.

A new method used to evaluate organic working fluids

International Nuclear Information System (INIS)

Zhang, Xinxin; He, Maogang; Wang, Jingfu

2014-01-01

In this paper, we propose a method named “Weight Classification-Hasse Dominance” to evaluate organic working fluids. This new method combines the advantages of both the method of weight determination and the Hasse Diagram Technique (HDT). It can be used to evaluate the thermodynamic performance, environmental protection indicator, and safety requirement of organic working fluid simultaneously. This evaluation method can offer good reference for working fluid selection. Using this method, the organic working fluids which have been phased out and will be phased out by the Montreal Protocol including CFCs (chlorofluorocarbons), HCFCs (hydrochlorofluorocarbons), and HFCs (hydrofluorocarbons) were evaluated. Moreover, HCs (hydrocarbons) can be considered as a completely different kind of organic working fluid from CFCs, HCFCs, and HFCs according to the comparison based on this new evaluation method. - Highlights: • We propose a new method used to evaluate organic working fluids. • This evaluation method can offer good reference for working fluid selection. • CFC, HCFC, and HFC working fluids were evaluated using this evaluation method. • HC can be considered as a totally different working fluid from CFC, HCFC, and HFC

to evaluate the work ability and health status of security guards at a public University. a cross-sectional, descriptive, and analytical study was carried with 119 security guards. The following instruments were used: Work Ability Index (WAI), Patient Health Questionnaire (PHQ-9), International Physical Activity Questionnaire (IPAQ, short), Alcohol Use Disorders Identification Test (AUDIT), Medical Outcomes Study (MOS), and Demand-Control-Support (DCS). Descriptive statistics were used to describe the study samples and the Spearman's coefficient correlation was performed to assess the WAI. Significance level was set at 5%. samples were composed by men; the mean age was 54.9 years (SD=5.7); 80% had partners, and 75% had basic education. The majority (95%) had only one job, the average length of service was 24.8 years (SD=11), ranging from 3 to 43 years. 88.9% worked ≤40 hours and 75% did not work at night shift or rotating shifts. The average score given to work ability was good (40.7 points), with significant correlation to social support at work (p-value=0.002), health conditions (p-value=0.094), and depression symptoms (p-value=0.054). this study showed that many characteristics might affect the work ability scores. Considering the results, we note that healthy life habits and a reorganization of work environments should be encouraged.
Long working hours and metabolic syndrome among Japanese men: a cross-sectional study

Science.gov (United States)

2012-01-01

Background The link between long working hours and health has been extensively studied for decades. Despite global concern regarding metabolic syndrome, however, no studies to date have solely evaluated the relationship between long working hours and that syndrome. We therefore examined the association between long working hours and metabolic syndrome in a cross-sectional study. Methods Between May and October 2009, we collected data from annual health checkups and questionnaires from employees at a manufacturing company in Shizuoka, Japan. Questionnaires were returned by 1,601 workers (response rate: 96.2%; 1,314 men, 287 women). After exclusions, including women because of a lack of overtime work, the analysis was performed for 933 men. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) for metabolic syndrome. Further, we conducted a stratified analysis by age-group (working hours and metabolic syndrome after adjusting for age, occupation, shift work, smoking status, frequency of alcohol consumption, and cohabiting status. Compared with subjects who worked 7–8 h/day, multivariate ORs for metabolic syndrome were 1.66 (95% CI, 0.91–3.01), 1.48 (95% CI, 0.75–2.90), and 2.32 (95% CI, 1.04–5.16) for those working 8–9 h/day, 9–10 h/day, and >10 h/day, respectively. Similar patterns were obtained when we excluded shift workers from the analysis. In age-stratified analysis, the corresponding ORs among workers aged ≥40 years were 2.02 (95% CI, 1.04–3.90), 1.21 (95% CI, 0.53–2.77), and 3.14 (95% CI, 1.24–7.95). In contrast, no clear association was found among workers aged working hours for increased risk of metabolic syndrome among Japanese male workers. PMID:22651100

Capture cross section evaluations were made for the 36 most important fission product absorbers in a fast reactor system. These evaluations were obtained by use of a generalized least-squares approach with calculations being performed with the computer code FERRET. These results will provide the major revisions to the ENDF/B-IV Fission Product Cross Section File which will be released as part of ENDF/B-V. Input for the cross section adjustment calculations included both integral and differential experimental data results. The differential cross sections and their uncertainties were obtained from the CSIRS library. Integral measurement results came from CFRMF and STEK Assemblies 500, 1000, 2000, 3000, and 4000. Comparisons of these evaluations with recent capture measurements are presented. 14 figures

Patients on sick leave due to work-related stress often complain about impaired concentration and memory. However, it is undetermined how widespread these impairments are, and which cognitive domains are most long-term stress sensitive. Previous studies show inconsistent results and are difficult to synthesize. The primary aim of this study was to examine whether patients with work-related stress complaints have cognitive impairments compared to a matched control group without stress. Our secondary aim was to examine whether the level of self-reported perceived stress is associated with neuropsychological test performance. We used a broad neuropsychological test battery to assess 59 outpatients with work-related stress complaints (without major depression) and 59 healthy controls. We matched the patients and controls pairwise by sex, age and educational level. Compared to controls, patients generally showed mildly reduced performance across all the measured domains of the neuropsychological test battery. However, only three comparisons reached statistical significance (p working memory. There were no statistical significant associations between self-reported perceived stress level and neuropsychological test performance. In conclusion, we recommend that cognitive functions should be considered when evaluating patients with work-related stress complaints, especially when given advice regarding return to work. Since this study had a cross-sectional design, it is still uncertain whether the impairments are permanent. Further study is required to establish causal links between work-related stress and cognitive deficits.

The codes and standards applicable to plant life extension have not been identified in the U.S. at this time. However, several initiatives have been taken to establish specific codes and standards pertaining to nuclear plant life extension (PLEX). One of these initiatives, sponsored by ASME, is the Section XI Special Working Group on Plant Life Extension (SWG-PLEX). The SWG-PLEX reports to the ASME Section XI Subcommittee and is responsible for recommending or drafting rules and requirements for modifying Section XI to accommodate age-related degradation to support nuclear plant life extension. This paper summarizes the results and reports the activities of the SWG-PLEX during the 1989/1990 period

Full Text Available Context: Work-related musculoskeletal disorders (WRMSD had been previously reported to have a high prevalence among dentists in different parts of the world. Aims: The study aimed to assess the prevalence of self-reported WRMSD among dental professionals in India. Material and Methods: A cross-sectional survey of 646 dentists (response rate of 82.97% was done using self-administered questionnaire which consisted of 27 items based on Nordic questionnaire for screening WRMSDs. Additional items of the questionnaire were added after preliminary content validation from six experienced dentists. Participant socio-demographic characteristics, work-related physical load characteristics, musculoskeletal symptom characteristics were evaluated. Statistical analysis used: All data were analyzed descriptively using percentiles and association between work-related physical load and WRMSD prevalence was done using Chi-square test. Results: All 536 dentists had at least one work-related musculoskeletal symptom in the previous year with an overall period prevalence rate of 100%. The type of symptoms present were pain (99.06%, stiffness (3.35%, fatigue (8.39%, discomfort (12.87%, clicks/sounds (4.1%, and other neurogenic (20.14%. The regions of symptoms were neck (75.74%, wrist/hand (73.13%, lower back (72.01%, shoulder (69.4%, hip (29.85%, upper back (18.65%, ankle (12.31%, and elbow (7.46%. Number of regions affected were two (82.83%, three (51.86%, four, or more (15.11%. Recurrent symptoms were present in 76.11%. Strong association was noted between sustained work postures and symptom regions for pain in WRMSD. Conclusion: The study found an overall one-year period prevalence rate of 100% for WRMSDs among Indian dentists. Measures for improving education and ergonomic evaluations are indicated on a large scale to prevent decline in work performance and incidence of WRMSDs among Indian dentists.

The knowledge of neutron cross-sections for Curium isotopes is necessary for solving the problems of the external fuel cycle. Experimental information on the cross-sections is very meager and does not satisfy requirements and existing evaluations in different libraries differ substantially for fission and (n,2n) reaction cross-sections. This situation requires a critical review of the entire set of evaluations of the neutron cross-sections for Curium. 17 refs, 3 figs

Knowledge and concern degree about work-related radiation hazards remained unknown among orthopedic surgeons. The aim of the cross-sectional study is to investigate whether the knowledge degree of work-related radiation is associated with psychological distress among orthopedic surgeons. This cross-sectional study sent electronic questionnaire via WeChat to orthopedic surgeons nationwide. Concern and knowing degree over radiation exposure was evaluated by a single self-reported question. Professional evaluation of concern degree was reflected by general psychological distress, which was assessed with the Kessler 10 scale (K10) and depressive symptoms with the Center for Epidemiologic Studies Depression Scale (CES-D). Only 43.23% (115/266) respondents knew well about radiation and a total of 78.20% (208/266) respondents considered radiation exposure as a great concern. Among those who reported concerns about radiation exposure, a total of 57.69% (120/208) respondents reported knowing little about radiation. Respondents who reported concerns over radiation exposure were significantly associated with higher scores on CES-D and K10 (P < .05). Among respondents who reported concerns over radiation exposure, those who have fewer knowledge about radiation, had higher CES-D and K10 scores than those who knew well about radiation (P < .05). Among respondents who reported no concerns over radiation exposure, those who knew little about radiation still had higher CES-D and K10 scores (P < .05). Fewer radiation knowledge tends to induce more radiation concerns associated with higher psychological distress in orthopedic surgeons. Radiation knowledge should be enhanced for surgeons who daily work with radiation-related fluoroscopy.
Application of the SAMINT methodology to the new cross section evaluations of 63Cu and 65Cu∗

Directory of Open Access Journals (Sweden)

Full Text Available The SAMINT methodology allows coupling of differential and integral data evaluations in a continuous-energy framework. Prior to development of the SAMINT code, integral experimental data such as in the International Criticality Safety Benchmark Experiments Project remained a tool for validation of completed nuclear data evaluations. Now, SAMINT extracts information from integral benchmarks in the form of calculated sensitivity coefficients by Monte Carlo codes such as CE TSUNAMI-3D or MCNP6 and combines it with the results of experimental cross section measurements to produce an updated cross section evaluation utilizing information from both sets of data. The use of the generalized linear least squares methodology ensures that proper weight is given to both the differential and integral data. SAMINT is not intended to bias nuclear data toward specific integral experiments, but it should be used to supplement evaluation of differential experimental data. This work demonstrates the application of the SAMINT methodology to the new Oak Ridge National Laboratory (ORNL evaluations of the resonance parameters for two isotopes of copper: 63Cu and 65Cu.

1990-05-01

The experimental data of total cross section were collected and evaluated for natural iron in the energy region from 1 keV to 20 MeV and for natural aluminium from 4.07 keV to 20 MeV. The evaluated data were recommended in the regions for them. The minimum values of Fe total cross section in the keV region were specially recommended. The resonance structures were briefly discussed for both Fe and Al. To make the evaluation better, all experimental measurements of neutron total cross section relative to Fe and Al were studied. Considering the resonance feature of medium weight nuclides, two criteria for selecting total cross section were presented: 1) the correlation between the precission of total cross section and neutron source; 2) the correlation between the accuracy of total cross section and the resolving power of the neutron spectrometer

1998-08-01

Within the framework of the SWG17 benchmark organized by a Working Party of the Nuclear Science Committee of the Nuclear Energy Agency (NEA), a comparison of lumped or pseudo fission product cross sections for fast reactors has been made. Four institutions participated with data libraries based on the JEF2.2, EAF-4.2, BROND-2, FONDL-2.1, ADL-3 and JENDL-3.2 evaluated nuclear data files. Several parameters have been compared with each other: the one-group cross sections and reactivity worths of the lumped nuclide for several partial absorption and scattering cross sections, and the one-group cross sections of the individual fission products. Also graphs of the multi-group cross sections of the lumped nuclide have been compared, as well as graphs of capture cross sections for 27 nuclides. From two contributions based on JEF2.2, it can be concluded that the data processing influences the capture cross section by about 1% and the inelastic scattering cross section by 2%. The differences between the lumped cross sections of the different data libraries are surprisingly small: maximum 6% for capture and 9% for the inelastic scattering. Similar results are obtained for the reactivity effects. Since the reactivity worth of the lumped nuclide is dominated by the capture reaction, the maximum spread in the total reactivity worth is still only 5.3%. There is a systematic difference between total, elastic and capture cross sections of JENDL-3.2 and JEF2.2 of the same order of magnitude. Possible reasons for this discrepancy have been indicated. The one-group capture and inelastic scattering cross sections of most of the important individual fission products differ by less than 10% (root mean square values). Larger differences are observed for unstable nuclides where there is a lack of experimental data. For the (n,2n) group cross sections, which are rather sensitive to the weighting spectrum in the fast energy range, these differences are several tens of percents. The final

Objectives To evaluate the satisfaction with work-life balance (WLB) and career satisfaction of gynecologic oncologists. Methods In August 2014, members of the Society of Gynecologic Oncology (SGO) were sent an anonymous, cross-sectional survey evaluating demographic variables, practice characteristics, career satisfaction, fatigue, and satisfaction with WLB. Fatigue was assessed using a visual-analog scale. Career satisfaction and WLB were assessed with a Likert scale. Inferential statistics were computed with type I error rates of 0.05. Results Out of the 1002 gynecologic oncologists surveyed, 290 (28.9%) responded. Only 18.6% of respondents were satisfied with WLB and there were significant associations between gender (P = 0.0157), time spent in work related activities at home (P = 0.0024), on weekends (P = 0.0017), and in the hospital (P = 0.0001). More than 84% of physicians reported they would choose medicine as a career again and of those 90% would choose to be a gynecologic oncologist again. Fatigue was strongly associated with dissatisfaction with WLB in univariate and multivariate analysis (P < 0.0001). Conclusions Although gynecologic oncologists indicated they are satisfied with their careers, most are not satisfied with their WLB. Given the forecast shortage of gynecologic oncologists and projected increased cancer rates, understanding the factors associated with career satisfaction may assist the SGO in meeting future gynecologic cancer care needs.

1975-07-01

Fast neutron total and scattering cross sections of elemental nickel are measured. Differential elastic scattering cross sections are determined from incident energies of 0.3 to 4.0 MeV. The cross sections for the inelastic neutron excitation of states at: 1.156 +- 0.015, 1.324 +- 0.015, 1.443 +- 0.015, 2.136 +- 0.013, 2.255 +- 0.030, 2.449 +- 0.030, 2.614 +- 0.020 and 2.791 +- 0.025 MeV are measured to incident neutron energies of 4.0 MeV. The total neutron cross sections are determined from 0.25 to 5.0 MeV. The experimental results are discussed in the context of optical and statistical models. It is shown that resonance width-fluctuation and correlation effects are significant. The present experimental and theoretical results, together with previously reported values, are used to construct a comprehensive evaluated elemental data file in the ENDF format. Some comparisons are made with previously reported evaluated files. In addition, some selected reactions which are widely used in dosimetry and other applications are presented as supplemental evaluated isotopic-data files. The numerical quantities are presented in tabular form. (3 tables, 29 figures)
New evaluations of neutron cross sections for 14N and 16O

Hale, G.M.; Young, P.G.; Chadwick, M.; Chen, Z.P.

1991-01-01

New evaluations of the neutron cross sections for 14 N and 16 O have been made for ENDF/B=VI. The evaluations are based at low energies on R-matrix analyses of reactions in the 15 N and 17 O systems, and at higher energies on GNASH calculations and experimental data evaluations, including covariance analyses. The 15 N system R-matrix analysis includes data from reactions among the channels n+ 14 N, p+ 14 C, and α+ 11 B at energies corresponding to excitations in 15 N below E x =13 MeV. The resonance structure of all cross sections in this energy range is fairly well reproduced. New data indicate a different J-value for the first resonance, however. Sub-threshold S-wave levels required to explain the large n+ 14 N total and elastic cross sections near zero energy give scattering lengths that differ significantly from the previous values. The R-matrix analysis of the 17 O system includes many new measurements of the n+ 16 O total cross section, done primarily at Oak Ridge and at Karlsruhe. The resonance structure of all the cross sections [total, (n,n), (n,α), and (α,α)] is well represented by the fit in the region below E n = 6.5 MeV. The new total cross section information gives different positions for some of the resonances and implies a different normalization for the (n,α) cross sections than that obtained in the ENDF/B-IV analysis. The evaluations at energies above the ranges of the R-matrix analyses incorporate results from a number of experiments performed since the previous ENDF/B evaluations. Especially important are new measurements of the total cross sections and differential elastic, and gamma-ray production cross sections

1980-04-01

Neutron total cross sections of elemental bismuth are measured with broad resolution from 1.2 to 4.5 MeV to accuracies of approx. = 1%. Neutron-differential-elastic-scattering cross sections of bismuth are measured from 1.5 to 4.0 MeV at incident neutron energy intervals of approx.< 0.2 MeV over the scattered-neutron angular range approx. = 20 to 160 deg. Differential neutron cross sections for the excitation of observed states in bismuth at 895 +- 12, 1606 +- 14, 2590 +- 15, 2762 +- 29, 3022 +- 21, and 3144 +- 15 keV are determined at incident neutron energies up to 4.0 MeV. An optical-statistical model is deduced from the measured values.

Changes in the modern economy have affected the financial sector. Time pressures, excessive work demands, and job stress are frequent concerns among bank employees, which might predispose them to burnout symptoms. The objective of the present study was to investigate the association between burnout symptoms and exposure to psychosocial work conditions in bank employees. A cross-sectional study of 1046 bank employees was carried out in Pará and Amapá, northern Brazil. We applied a self-administered questionnaire evaluating socio-demographic characteristics, burnout (Maslach Burnout Inventory), and two job stress models (Demand-Control-Support and Effort-Reward Imbalance). Two levels of burnout symptoms were analysed: moderate level of burnout (MLB) and high level of burnout (HLB). Logistic regression models were used to estimate associations between the two levels of burnout and the two stress models, controlling for relevant covariates. The overall prevalence of burnout was 71.8% (31.1% for HLB; 40.7% for MLB), regardless of gender. Exposure to adverse psychosocial conditions in the workplace, such as high strain, low social support at work, high effort/low reward, and over commitment showed strong association with HLB and MLB, and these associations were independent of age, gender, and other occupational characteristics. We found that psychosocial conditions in the financial sector involving high strain, low social support at work, high effort/low reward, and over commitment represent possible risk factors for moderate and HLB symptoms in bank employees. © The Author 2016.

International mobility of health care professionals is increasing, though little is known about how working in a culturally diverse team affects the native physicians' psychosocial work environment. We examined Finnish physicians' perceptions of work-related wellbeing according to whether they had foreign-born colleagues (FBCs) in their work unit. We also examined whether work-related resources moderate the potential association between work-related wellbeing and working alongside FBCs. A cross-sectional survey was conducted for a random sample of physicians in Finland in 2010 (3826 respondents, response rate 55%). Analyses were restricted to native Finnish physicians working in public health care. The results were analyzed by ANCOVA. In unadjusted analyses, having FBCs was related to poor team climate (pwork unit (p=0.007 for interaction between FBCs and procedural justice and pculturally diverse work units face challenges related to team climate and job satisfaction. The results also show that leadership plays an important role in culturally diverse work units. The potential challenges of culturally diverse teams for native physicians may be reduced by fair decision-making and by increasing physicians' job control. Copyright © 2014 Elsevier Ireland Ltd.

With increasing age, physical capacity decreases, while the need and time for recovery increases. At the same time, the demands of work usually do not change with age. In the near future, an aging and physically changing workforce risks reduced work ability. Therefore, the impact of different factors, such as physical activity, on work ability is of interest. Thus, the aim of this study was to evaluate the association between physical activity and work ability using both cross sectional and prospective analyses. This study was based on an extensive questionnaire survey. The number of participants included in the analysis at baseline in 2004 was 2.783, of whom 2.597 were also included in the follow-up in 2006. The primary outcome measure was the Work Ability Index (WAI), and the level of physical activity was measured using a single-item question. In the cross-sectional analysis we calculated the level of physical activity and the prevalence of poor or moderate work ability as reported by the participants. In the prospective analysis we calculated different levels of physical activity and the prevalence of positive changes in WAI-category from baseline to follow-up. In both the cross sectional and the prospective analyses the prevalence ratio was calculated using Generalized Linear Models. The cross-sectional analysis showed that with an increased level of physical activity, the reporting of poor or moderate work ability decreased. In the prospective analysis, participants reporting a higher level of physical activity were more likely to have made an improvement in WAI from 2004 to 2006. The level of physical activity seems to be related to work ability. Assessment of physical activity may also be useful as a predictive tool, potentially making it possible to prevent poor work ability and improve future work ability. For employers, the main implications of this study are the importance of promoting and facilitating the employees' engagement in physical activity, and

Work engagement is related to mental health, but studies of physical health's association with work engagement are scarce. This study aims to evaluate the relationship between physical health, psychosocial risk factors and work engagement among Finnish women in municipal work units. A cross-sectional study was conducted in 2014 among 726 female employees from 10 municipal work units of the city of Pori, Finland. Work engagement was assessed with the nine-item Utrecht Work Engagement Scale. The American Heart Association's concept of ideal cardiovascular health (CVH) was used to define physical health (non-smoking, body mass index work engagement. In subjects without psychosocial risk factors (36.7%), work engagement was high and stable. Presence of even one psychosocial risk factor was associated with a lower level of work engagement regardless of the sum of ideal CVH metrics. Both physical and mental health factors have a positive relationship with work engagement, whereas the presence of even one psychosocial risk factor has a negative association regardless of the level of classic cardiovascular risk factors. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Nuclear data, along with numerical methods and the associated calculation schemes, continue to play a key role in reactor design, reactor core operating parameters calculations, fuel cycle management and criticality safety calculations. Due to the intensive use of Monte-Carlo calculations reducing numerical biases, the final accuracy of neutronic calculations increasingly depends on the quality of nuclear data used. This paper gives a broad picture of all ingredients treated by nuclear data evaluators during their analyses. After giving an introduction to nuclear data evaluation, we present implications of using the Bayesian inference to obtain evaluated cross sections and related uncertainties. In particular, a focus is made on systematic uncertainties appearing in the analysis of differential measurements as well as advantages and drawbacks one may encounter by analyzing integral experiments. The evaluation work is in general done independently in the resonance and in the continuum energy ranges giving rise to inconsistencies in evaluated files. For future evaluations on the whole energy range, we call attention to two innovative methods used to analyze several nuclear reaction models and impose constraints. Finally, we discuss suggestions for possible improvements in the evaluation process to master the quantification of uncertainties. These are associated with experiments (microscopic and integral), nuclear reaction theories and the Bayesian inference.

This study examined the relationship between psychosocial working factors such as job control, job demands, job insecurity, supervisor support, and workplace bullying as risk factors for suicide ideation. We used a logistic analytic approach to assess risk factors for thoughts of suicide in a cross-sectional sample of working Australians. Potential predictors included psychosocial job stressors (described above); we also controlled for age, gender, occupational skill level, and psychological distress. We found that workplace bullying or harassment was associated with 1.54 greater odds of suicide ideation (95% confidence interval 1.64 to 2.05) in the model including psychological distress. Results also suggest that higher job control and security were associated with lower odds of suicide ideation. These results suggest the need for organizational level intervention to address psychosocial job stressors, including bullying.

The Monte Carlo simulation of the interaction of neutrons with matter relies on evaluated nuclear data libraries and models. The evaluated libraries are compilations of measured physical parameters (such as cross sections) combined with predictions of nuclear model calculations which have been adjusted to reproduce the experimental data. The results obtained from the simulations depend largely on the accuracy of the underlying nuclear data used, and thus it is important to have access to the nuclear data libraries available, either of general use or compiled for specific applications, and to perform exhaustive validations which cover the wide scope of application of the simulation code. In this paper we describe the work performed in order to extend the capabilities of the GEANT4 toolkit for the simulation of the interaction of neutrons with matter at neutron energies up to 20 MeV and a first verification of the results obtained. Such a work is of relevance for applications as diverse as the simulation of a n...

To evaluate the impact of RA on work capacity and identify factors related to work capacity impairment in patients with RA. A cross-sectional multicentre study was performed in 21 tertiary care hospitals across China. A consecutive sample of 846 patients with RA was recruited, of which 589 patients of working age at disease onset constituted the study population. Information on the socio-demographic, clinical, working and financial conditions of the patients was collected. Logistic regression analyses were used to identify factors associated with work capacity impairment. The rate of work capacity impairment was 48.0% in RA patients with a mean disease duration of 60 months (interquartile range 14-134 months), including 11.7% leaving the labour force early, 33.6% working reduced hours and 2.7% changing job. Multivariable logistic regression analysis showed that reduced working hours was significantly related to current smoking [odds ratio (OR) 2.07 (95% CI 1.08, 3.97)], no insurance [OR 1.94 (95% CI 1.20, 3.12)], in manual labour [OR 2.66 (95% CI 1.68, 4.20)] and higher HAQ score [OR 2.22 (95% CI 1.36, 3.60)]. There was an association of current smoking [OR 3.75 (95% CI 1.54, 9.15)], in manual labour [OR 2.33 (95% CI 1.17, 4.64)], longer disease duration [OR 1.01 (95% CI 1.00, 1.01)] and lower BMI [OR 0.90 (95% CI 0.82, 0.99)] with leaving the labour force early. There is a substantial impact of RA on the work capacity of patients in China. Social-demographic, disease- and work-related factors are all associated with work capacity impairment. © The Author 2015.

The study aimed to develop and validate a model to measure psychosocial factors at work among medical staff in China based on confirmatory factor analysis (CFA). The second aim of the current study was to clarify the association between stress-related psychosocial work factors and suboptimal health status. The cross-sectional study was conducted using clustered sampling method. Xuanwu Hospital, a 3A grade hospital in Beijing. Nine hundred and fourteen medical staff aged over 40 years were sampled. Seven hundred and ninety-seven valid questionnaires were collected and used for further analyses. The sample included 94% of the Han population. The Copenhagen Psychosocial Questionnaire (COPSOQ) and the Suboptimal Health Status Questionnaires-25 were used to assess the psychosocial factors at work and suboptimal health status, respectively. CFA was conducted to establish the evaluating method of COPSOQ. A multivariate logistic regression model was used to estimate the relationship between suboptimal health status and stress-related psychosocial work factors among Chinese medical staff. There was a strong correlation among the five dimensions of COPSOQ based on the first-order factor model. Then, we established two second-order factors including negative and positive psychosocial work stress factors to evaluate psychosocial factors at work, and the second-order factor model fit well. The high score in negative (OR (95% CI)=1.47 (1.34 to 1.62), Pwork factors increased and decreased the risk of suboptimal health, respectively. This relationship remained statistically significant after adjusting for confounders and when using different cut-offs of suboptimal health status. Among medical staff, the second-order factor model was a suitable method to evaluate the COPSOQ. The negative and positive psychosocial work stress factors might be the risk and protective factors of suboptimal health, respectively. Moreover, negative psychosocial work stress was the most associated

To study work participation of persons with hearing loss, and associations with hearing disabilities, self-reported workability, fatigue and work accommodation. Cross-sectional internet-based survey. A total of 10,679 persons with hearing loss within working-age were invited to answer the survey, where 3330 answered (35.6%). Degree of hearing loss was associated with low workability, fatigue and work place accommodation, while sick leave was associated with fatigue. Degree of hearing loss was positively associated with being unemployed (p part-time work (p < .01) (often combined with disability benefits) for women. Work place accommodation was more frequently provided among respondents working with sedentary postures, high seniority, long-term sick leave or low workability. Additional unfavourable sensory conditions were associated with decreased employment (p < .001) and workability, and an increase in sick leave (p < .01) and fatigue (p < .001). Hearing loss seemed to influence work participation factors negatively; particularly, for moderate hearing loss and for women, even though the degree of employment was high. A lack of work place accommodation when there was a need for such was found. This implies increased attentiveness towards individual needs concerning the experienced disability a hearing loss may produce. A more frequent use of hearing disability assessment is suggested.

Improving the resiliency of healthcare workers is a national imperative, driven in part by healthcare workers having minimal exposure to the skills and culture to achieve work-life balance (WLB). Regardless of current policies, healthcare workers feel compelled to work more and take less time to recover from work. Satisfaction with WLB has been measured, as has work-life conflict, but how frequently healthcare workers engage in specific WLB behaviours is rarely assessed. Measurement of behaviours may have advantages over measurement of perceptions; behaviours more accurately reflect WLB and can be targeted by leaders for improvement. 1. To describe a novel survey scale for evaluating work-life climate based on specific behavioural frequencies in healthcare workers.2. To evaluate the scale's psychometric properties and provide benchmarking data from a large healthcare system.3. To investigate associations between work-life climate, teamwork climate and safety climate. Cross-sectional survey study of US healthcare workers within a large healthcare system. 7923 of 9199 eligible healthcare workers across 325 work settings within 16 hospitals completed the survey in 2009 (86% response rate). The overall work-life climate scale internal consistency was Cronbach α=0.790. t-Tests of top versus bottom quartile work settings revealed that positive work-life climate was associated with better teamwork climate, safety climate and increased participation in safety leadership WalkRounds with feedback (pwork setting. The work-life climate scale exhibits strong psychometric properties, elicits results that vary widely by work setting, discriminates between positive and negative workplace norms, and aligns well with other culture constructs that have been found to correlate with clinical outcomes.

Better opportunities for recovery at work are thought to be associated with work ability in a young workforce but evidence is scarce to lacking. The aim of this study was to examine cross-sectional associations between opportunities for recovery at work and excellent work ability among young workers and specifically for young workers with high work demands. A study group of 1295 women and 1056 men aged 18-29 years was selected from three biennial years of a population cohort. The subsample reporting high work demands consisted of 439 women and 349 men. The study group had completed a work environment questionnaire in a survey conducted by Statistics Sweden. Associations between opportunities for recovery at work and excellent work ability were assessed by multiple logistic regression models stratified for gender. Having varied work was associated with excellent work ability in all young men (p men with high work demands (p = 0.019; PR 1.3). For the latter group the possibility of deciding when to perform a work task was also associated with excellent work ability (p = 0.049; PR 1.3). Among young women with high work demands, the possibility of deciding one's working hours was associated with excellent work ability (p = 0.046; PR 1.2). For young men, having varied work can contribute to excellent work ability. In addition, for men with high work demands, the possibility of deciding when to perform a work task may be favourable for excellent work ability. For young women with high work demands, the possibility of deciding one's working hours can contribute to excellent work ability. Employers could use these opportunities for recovery in promoting work ability among young workers.

We present evaluations of the interaction of neutrons with energies between 20 and 100 MeV with oxygen and nitrogen nuclei, which follows on from our previous work on carbon. Our aim is to accurately represent integrated cross sections, inclusive emission spectra, and kerma factors, in a data library which can be used in radiation transport calculations. We apply the FKK-GNASH nuclear model code, which includes Hauser-Feshbach, preequilibrium, and direct reaction mechanisms, and use experimental measurements to optimize the calculations. We determine total, elastic, and nonelastic cross sections, angle-energy correlated emission spectra for light ejectiles with A {<=} 4 and gamma-rays, and average energy depositions. Our results for charged-particle emission spectra agree well with the measurements of Subramanian et al. We compare kerma factors derived from our evaluated cross sections with experimental data, providing an integral benchmarking of our work. (author). 52 refs.

Full Text Available Firefighting is extremely strenuous and physically demanding work and involves ability to cope with emergency life-or-death situations. Because of the high physical demands of firefighting, successful job performance and minimizing of morbidity and mortality depends on fitness for duty. The firefighting department of Tehran does not perform periodic medical assessment for firefighters. The aim of this study was to evaluate medical fitness among firefighters in Tehran. In this cross sectional study we examined 147 firefighters. Medical and occupational history obtained by interview, then we performed physical examination, blood tests, ECG, spirometry and audiometry. Then results compared with guidelines for firefighters in the USA, Australia and the United Kingdom. Seven percent of our participants had a kind of pulmonary dysfunction and 25% had some degrees of hearing loss. A considerable percent of them had modifiable coronary heart disease risk factors. Thirteen participitants were unfit for this job that among them; ten firefighters were unfit based on vision capability, one case due to hypertention and two cases because of pulmonary dysfunction. Because of hazardouse nature of firefighting; preplacement, periodic medical evaluations and assesment of fitness for firefighters in Iran is highly recommended. Establishment of fitness criteria for firefighters in Iran is necessery to perform assigned functions safely.
Development of improved procedures for evaluation of neutron cross sections for reactor neutron dosimetry

The cross-sections for the four important neutron dosimetry reactions 19 F(n,2n) 18 F, 31 P(n,p) 31 Si, 93 Nb(n,n')sup(93m)Nb and 103 Rh(n,n')sup(103m)Rh were evaluated in the neutron energy range from threshold to 20 MeV. For the 19 F(n,2n) reaction the evaluation could be based entirely on experimental data; for the reactions 31 P(n,p) 31 Si and 103 Rh(n,n')sup(103m)Rh large gaps in the experimental excitation functions and large discrepancies between the existing data made it necessary to supplement the experimental data by cross-section calculations and to give about equal weight to the experimental and calculated cross-sections. For the 93 Nb(n,n')sup(93m)Nb reaction the evaluation had to be based entirely on the theoretically calculated cross-sections. The cross-section calculations were performed using the statistical model of nuclear reactions allowing for precompound processes in the first reaction step and errors of the calculated cross-sections were estimated from their sensitivity to the various input parameters. Cross-section values were evaluated for energy groups between 0.1 MeV and 1 MeV wide, the width depending on both the slope of the excitation functions and the density of the available data. For each evaluated cross-section also an uncertainty (on a 1 sigma confidence level) was derived taking into account the errors given by the experimentalists, the general consistency of the experimental data and the estimated errors of the theoretically calculated cross-sections. In addition relative correlation matrices were derived for each evaluated excitation function describing the correlations between the uncertainties of the cross-sections at different energies. The correlations between the cross-section uncertainties for different reactions were found to be negligible. The results of this evaluation as well as those of Ref. 1 will be combined with the ENDF/B-V dosimetry file into an international neutron dosimetry file by the nuclear data section of

Full Text Available Background:Irregular Working hours, including night work and shift work,have been found to be associated with alteration in various levels of biochemical factors. And some studies have showed association between shift work and blood biochemical disturbances in blood. In this epidemiological study we investigated,whether regular schedule of working hours can minimize the associated biochemical effects.Methods: Atotal of 442 air traffic controllers between the ages of 21 and 59 years in this study filled out questionnaire, and triglyceride, total cholesterol, and HDL-C concentration and FBS were measured after 12- hours fasting. The correlation between shift work and the biochemical variables was measured. The SPSS software version 11.5 and STATAversion 8 were used for statistical analysis, the X2 and fisher's exact test used for comparing the qualitative variables and the parametric tests for quantitative variables with normal distribution. Odd's ratio (OR, and 95% confidence interval (95% CI were used for estimating the effect of shift work on lipid profile and high blood glucose levels. Logistic regression modeling was used for multivariable analysis and adjusting the effect of different variables.Results: sample size of this cross-sectional study was consisted of 305(69% shift workers and 137(31% day workers. The mean age of the shift workers was 40 ± 10 years old and the day workers 40 ± 9.The mean of variables in the present study for total cholesterol, LDL-C, HDL-C, triglyceride and fasting blood glucose in the shift workers were respectively: 195±37mg/dl, 116.8±34.8mg/dl, 48.2±15.1mg/dl, 154±80mg/dl, 92±20mg/dl and in the day workers were respectively: 200±40mg/dl, 125.3±38.6mg/dl, 48.8±23.3mg/dl,151± 77mg/dl, 90± 14mg/dl.

Research addressing links of work stress or family stress with asthma is constrained by (1) inconsistent evidence, (2) failure to consider the combined exposure to work stress and family stress, and (3) its primary focus on Western study populations. We aimed to address these knowledge gaps. We used cross-sectional data collected in 2015 among 7816 women from five professional groups in five Chinese cities. Work stress was measured by the 10-item effort-reward imbalance (ERI) questionnaire. Family stress was assessed by a psychometrically evaluated instrument comprising five items on, e.g., familial conflicts or domestic workload. Asthma was operationalized by self-reports of a physician diagnosis. Associations were examined by multivariable logistic regression estimating odds ratios (ORs) and 95% confidence intervals (CIs). Both high work stress (i.e., ERI score >1) and high family stress (i.e., score above the median) were associated with asthma (OR 1.66, 95% CI 1.22-2.27 and OR 1.48, 95% CI 1.10-1.99, respectively). Women with combined exposure (versus none) had somewhat higher odds of asthma (OR 2.13, 95% CI 1.42-3.19) than those with sole exposure to either work stress (OR 1.89, 95% CI 1.20-2.96) or family stress (OR 1.71, 95% CI 1.03-2.84). Interaction terms were significant for continuous variables (p = 0.046), but not for dichotomized variables (p = 0.199). The present study suggests that both work stress and family stress are positively associated with asthma in women in China. Further, the combined exposure may be associated with a further excess of asthma occurrence. Longitudinal studies are needed to confirm our findings and to explore potential temporal relationships.

Suboptimal health status (SHS)-an intermediate state between health and illness--refers to functional somatic symptoms that are medically undiagnosed. Although- SHS has become a great challenge for global public health, very little about its etiology and mechanisms are known. Work-recreation balance is a part of work-life balance, and is related to stress which greatly influences health status. We therefore carried out a cross-sectional investigation between 2012 and 2013 within a clustered sample of 24,475 individuals aged 15-60 years from a population in southern China. In so doing, we hoped to illuminate the associations between work-recreation balance conditions, healthy lifestyles, and SHS. Work-recreation balance conditions were categorically defined by frequency ("rarely, sometimes, or always"). Health-Promoting Lifestyle Profile (HPLP-II) was used to evaluate the level of healthy lifestyles, and the medical examination report and Sub-Health Measurement Scale V1.0 (SHMS V1.0) were both used to evaluate health status. The ratio of SHS (46.3%) is higher than health status (18.4%) or disease status (35.3%). Overall, 4.9% of respondents reported the lowest level of work-recreation balance, and they scored lower on both the HPLP-II and SHMS V1.0 compared with those who frequently maintained a work-recreation balance. Significant association was found between work-recreation balance behaviors and healthy lifestyles (p work-recreation balance, individuals whose work-recreation balance was categorically "rare" were 1.69 times as likely to develop SHS (odds ratio (OR): 1.69, 95% confidence interval (CI): 1.49-1.92), and those with infrequent work-recreation balance ("sometimes") were 1.71 times more likely to develop SHS (OR: 1.71, 95% CI: 1.62-1.81). These findings suggest that work-recreation balance conditions are significantly associated with, and seem to be accurate behavioral indicia of a healthy lifestyle. Poor work-recreation balance is associated with

Nurses are key staff members of health-care organizations. Nurse engagement directly influences quality of care and organizational performance. The purpose of the present study was to understand the state of work engagement and explore its predictors among registered nurses in China by using a descriptive, cross-sectional survey design (n = 1065). Work engagement was measured with the Chinese version of the Utrecht Work Engagement Scale. The results showed that the average work engagement of Chinese nurses was 3.54 (standard deviation = 1.49), and that nurses' age (β = .16, t = 5.32), job characteristics (β = .33, t = 9.43), and practice environment (β = .23, t = 6.59) were significant predictors of work engagement. Thus, nurse leaders should be encouraged to shape motivational job characteristics and create supportive practice environment so as to increase nurses' work engagement. © 2018 John Wiley & Sons Australia, Ltd.

It has been suggested that the relationship between work stress and somatic symptoms (e.g., cardiopulmonary, gastrointestinal complaints, general pain, and fatigue) is particularly pronounced in women. As evidence from China is sparse, we used a large sample of Chinese working women to test those potential associations. Data were obtained from a cross-sectional study of 6826 working women in five urban areas in China who were free from major clinical disease. The sample was drawn from five occupations (physicians, nurses, school teachers, bank employees, and industrial workers). The Effort-Reward Imbalance Questionnaire and Patient Health Questionnaire-15 were used to measure work stress and somatic symptoms, respectively. Multivariate ordinal logistic regression was performed to analyze the associations. 52.6% participants reported high work stress in terms of concurrent high effort and low reward. The distribution of severity of somatic symptoms covered the full range from minimal (37.3%) and low (30.6%), to medium (19.7%) and high (12.4%). The adjusted odds ratio of somatic symptoms by high work stress was 2.45 (95% confidence interval=2.24-2.68), and all single psychosocial work factors (effort, reward, and over-commitment) exerted substantial effects on somatic symptoms (odds ratios>2.00). Work stress is strongly associated with somatic symptoms in Chinese working women. Future longitudinal studies and intervention studies are needed to understand and improve women's psychosocial work environment and their psychosomatic health in China and elsewhere.

The aim of this study was to determine: 1) if quality of work life (QWL), location of cross-training, stress variables, and various demographic factors in nurses are associated with work ability, and 2) nursing occupational stress, QWL, and various associated factors are related with nurses' work ability. There is limited research examining the obstetrical nursing environment. Given the amount of time and energy people expend at the workplace, it is crucial for employees to be satisfied with their lives at work. This cross sectional study was conducted in 2012 in four hospitals in northeastern Ontario, Canada. A stratified random sample of registered nurses (n= 111) were selected. The majority of participants were female (94.6%) ranging in age from 24 to 64 years (M = 41.9, s.d. = 10.2). For the stress and QWL model, one variable: QWL (home-work support - see Methods for definition) (p= 0.015), cross-trained (see Methods for definition) nurses (p= 0.048), and having more than 4 patients per shift (p= 0.024) significantly contributed to the variance in work ability scores. In the logistic regression model, the odds of a higher work ability for nurses who received home-work support were estimated to be 1.32 (95% CI, 1.06 to 1.66) times the odds of a higher work ability for nurses who did not receive home-work support. Work ability in the work environment of obstetrical nursing is important. To be high functioning, workplaces should maximize the use of their employees' actual and potential skills.

A comparison is made between recent evaluations of fission-product cross sections as given in the CNEN/CEA, ENDF/B-IV, ENDF/V-V, JENDL-1, RCN-2 and RCN-3 data libraries. The intercomparison is restricted to 24 important fission products in a fast power reactor. The evaluation methods used to obtain the various data files are reviewed and possible shortcomings are indicated. A survey is given of the experimental data based used in the various evaluations. Some graphs are included showing the new ENDF/B-V and RCN-3 fastcapture cross-section evaluations. Further intercomparisons are made by means of multi-group and one-group cross sections. It is shown that lumped fission-product cross sections calculated from the most recent versions of the data files are in quite good agreement with each other. This review concludes with a discussion on observed discrepancies and requests for new measurements. 78 references

Full Text Available Electronic health record (EHR is a digital data format that collects electronic health information about an individual patient or population. To enhance the meaningful use of EHRs, information extraction techniques have been developed to recognize clinical concepts mentioned in EHRs. Nevertheless, the clinical judgment of an EHR cannot be known solely based on the recognized concepts without considering its contextual information. In order to improve the readability and accessibility of EHRs, this work developed a section heading recognition system for clinical documents. In contrast to formulating the section heading recognition task as a sentence classification problem, this work proposed a token-based formulation with the conditional random field (CRF model. A standard section heading recognition corpus was compiled by annotators with clinical experience to evaluate the performance and compare it with sentence classification and dictionary-based approaches. The results of the experiments showed that the proposed method achieved a satisfactory F-score of 0.942, which outperformed the sentence-based approach and the best dictionary-based system by 0.087 and 0.096, respectively. One important advantage of our formulation over the sentence-based approach is that it presented an integrated solution without the need to develop additional heuristics rules for isolating the headings from the surrounding section contents.

To determine the prevalence of Streptococcus mutans (MS) in mother-child pairs and to evaluate the correlation in the levels of salivary MS of working and nonworking mothers with that of their children and their associations with other related factors. A cross-sectional study was carried out among 100 mother-child pairs residing in New Multan Nagar Colony, New Delhi, India. A total of 50 children with their mothers were included in the working group and another 50 were included in the nonworking group. A questionnaire regarding the feeding habits, oral hygiene habits, daily intake of sugars of the children along with their weaning time was carried out. All mothers and children were clinically examined for recording decayed, extracted, and filled teeth (deft)/decayed, missing, and filled teeth (DMFT), and whole unstimulated saliva was collected and cultured for MS in the laboratory. The data were collected and subjected to statistical analysis using chi-square, Spearman's correlation, and logistic regression analysis. The prevalence of salivary MS in the children was 69%. A statistically significant correlation was found between the oral levels of MS in nonworking and working mother-child pairs. Regression analysis showed that those children who feed by bottle for more than 12 months, have daily sweet intake, have sugars in feeding bottle and have higher defts were more likely to have mutans score of 1 or 2. The mother, working or nonworking, being the primary care provider is the major source of transmission of MS to their child irrespective of the amount of time spent with them.

Stressed workers suffer from severe health problems which appear to have increased. Poor leadership is especially considered a source of stress. Indeed, supervisors might perceive their subordinates to be similar to them as far as stress is concerned and this might more widespread in organizations than previously thought. The present research investigates the relationships between leaders' health, in terms of work-related stress, mental health, and workplace bullying and their evaluation of subordinates' stress. Five regression models were formulated to test our hypothesis. This is a cross-sectional study among 261 Italian leaders, using supervisor self-assessment and leaders' assessments of their subordinates. Leaders' health was related to their evaluation of staff stress. Job demand, lack of job control, and lack of support by colleagues and supervisors evaluated in their subordinates were particularly associated with the leaders' own health. Implications for developing healthy leaders are finally discussed.

In a work environment, it is important to identify and quantify the relationship among work activities, working posture, and workplace design. Working posture may impact the physical comfort and well-being of individuals, as well as performance. The Posture Video Analysis Tool (PVAT) is an interactive menu and button driven software prototype written in Supercard (trademark). Human Factors analysts are provided with a predefined set of options typically associated with postural assessments and human performance issues. Once options have been selected, the program is used to evaluate working posture and dynamic tasks from video footage. PVAT has been used to evaluate postures from Orbiter missions, as well as from experimental testing of prototype glove box designs. PVAT can be used for video analysis in a number of industries, with little or no modification. It can contribute to various aspects of workplace design such as training, task allocations, procedural analyses, and hardware usability evaluations. The major advantage of the video analysis approach is the ability to gather data, non-intrusively, in restricted-access environments, such as emergency and operation rooms, contaminated areas, and control rooms. Video analysis also provides the opportunity to conduct preliminary evaluations of existing work areas.

Mouth breathing syndrome is very common among school-age children, and it is possibly related to learning difficulties and low academic achievement. In this study, we investigated working memory, reading comprehension and arithmetic skills in children with nasal and mouth breathing. Analytical cross-sectional study with control group conducted in a public university hospital. 42 children (mean age = 8.7 years) who had been identified as mouth breathers were compared with a control group (mean age = 8.4 years) matched for age and schooling. All the participants underwent a clinical interview, tone audiometry, otorhinolaryngological evaluation and cognitive assessment of phonological working memory (numbers and pseudowords), reading comprehension and arithmetic skills. Children with mouth breathing had poorer performance than controls, regarding reading comprehension (P = 0.006), arithmetic (P = 0.025) and working memory for pseudowords (P = 0.002), but not for numbers (P = 0.76). Children with mouth breathing have low academic achievement and poorer phonological working memory than controls. Teachers and healthcare professionals should be aware of the association of mouth breathing with children's physical and cognitive health.

Full Text Available This theoretical article describes and discusses the concept of quality in relation to the evaluation of social-work practice. Of particular interest are the difference between quality of services and quality of life and the importance of balancing the stakeholders’ different interests in order to make a sound judgement of quality in social work possible. This article begins with presenting some basic perspectives on quality as well as the transference of the concept of quality from manufacturing industry to social-work practice. Thereafter the two main issues are discussed: the concepts of quality of service and of quality of life and the importance of balancing different stakeholders’ perspectives in the evaluation of quality in social-work practice. This article concludes that: 1 it is crucial to be aware of and to consider the distinction between quality of service and quality of life; 2 clients’ perspective on quality of life is an aspect of outcome that currently receives insufficient attention; 3 clients’ subjective experiences of welfare of well-being deserve greater attention for ethical as well as methodological reasons; and 4 judgement of quality in social work are inevitably dependent on different stakeholders’ perspectives.

This report summarises the work performed under WPEC Subgroup 32 (SG32) on issues pertinent to the methodology used in the unresolved resonance region (URR). The main purpose of SG32 was to verify the validity of the Single-level Breit-Wigner (SLBW) cross-section representation in the URR for self-shielding calculations. While SG32 work was under way, several other developments related to the URR on this subject came into play that had a direct impact on the results of calculations. The work described in this report focuses on: - testing of the SLBW formalism in the URR for fissile and fertile isotopes; - URR covariance representation; - interpolation issue with a URR resonance parameter for the infinitely dilute cross-section calculations; - ENDF URR parameter representation based on the LSSF = 0 or LSSF = 1 option

Work-family conflicts and self-reported work ability: cross-sectional findings in women with chronic musculoskeletal disorders.

Under conditions of gender-specific division of paid employment and unpaid childcare and housework, rising employment of women increases the likelihood that they will be faced with work-family conflicts. As recent research indicates, such conflicts might also contribute to musculoskeletal disorders. However, research in patient samples is needed to clarify how important these conflicts are for relevant health-related measures of functioning (e.g., work ability). We therefore examined, in a sample of women with chronic musculoskeletal disorders, the indirect and direct associations between the indicators of work-family conflicts and self-reported work ability as well as whether the direct effects remained significant after adjustment for covariates. A cross-sectional questionnaire-based study was conducted. Participants were recruited from five rehabilitation centers. Work-family conflicts were assessed by four scales referring to time- and strain-based work interference with family (WIF) and family interference with work (FIW). Self-reported work ability was measured by the Work Ability Index. A confirmatory factor analysis was performed to approve the anticipated four-factor structure of the work-family conflict measure. Direct and indirect associations between work-family conflict indicators and self-reported work ability were examined by path model analysis. Multivariate regression models were performed to calculate adjusted estimators of the direct effects of strain-based WIF and FIW on work ability. The study included 351 employed women. The confirmatory factor analysis provided support for the anticipated four-factor structure of the work-family conflict measure. The path model analysis identified direct effects of both strain-based scales on self-reported work ability. The time-based scales were indirectly associated with work ability via the strain-based scales. Adjusted regression analyses showed that a five-point increase in strain-based WIF or FIW was
Evaluation of the n + 3H Cross Section at En=14 MeV

Energy Technology Data Exchange (ETDEWEB)

The n + {sup 3}H cross section is important for NIF diagnostics. As the d-{sup 3}H fusion at NIF generates neutrons with an energy of 14 MeV, the precise knowledge of the n + {sup 3}H cross section and in particular the elastic cross section at that energy is crucial. Experimental data at E{sub n} = 14 MeV are not accurate with large disagreements among different sets of measurements. On the other hand, the mirror reaction p-{sup 3}He is well studied and accurate data are available in a wide range of proton energies. We use several theoretical approaches to evaluate the n-{sup 3}H cross section by fine-tuning the theory to reproduce the p-{sup 3}He elastic differential cross sections. The good agreement between the R-matrix analysis and scaled ab initio calculations gives us confidence that our evaluated n + {sup 3}H cross section is accurate with an uncertainty on the order of 5%.

Prospective studies exploring the associations between a large range of occupational factors and psychotropic drug use among national samples of workers are seldom. This study investigates the cross-sectional and prospective associations between occupational factors, including a large set of psychosocial work factors, and psychotropic drug use in the national French working population. The study sample comprised 7542 workers for the cross-sectional analysis and 4213 workers followed up for a 4-year period for the prospective analysis. Psychotropic drug use was measured within the last 12 months and defined by the use of antidepressants, anxiolytics or hypnotics. Three groups of occupational factors were explored: classical and emergent psychosocial work factors, working time/hours and physical work exposures. Weighted Poisson regression analyses were performed to adjust for covariates. In the cross-sectional analysis, psychological demands, low social support and hiding emotions were associated with psychotropic drug use. Job insecurity for men and night work for women were associated with psychotropic drug use. In the prospective analysis, hiding emotions and physical exposure were predictive of psychotropic drug use. Dose-response associations were observed for the frequency/intensity of exposure and repeated exposure to occupational factors. This study underlines the role of psychosocial work factors, including emergent factors, in psychotropic drug use. Prevention policies oriented toward psychosocial work factors comprehensively may be useful to reduce this use. Copyright © 2015 Elsevier Ltd. All rights reserved.

Work-related stress is a pattern of reactions to work demands unmatched to nurses' knowledge, skills, or abilities; these challenges exceed their ability to cope, resulting in burnout, turnover, and low quality patient care. An institution-based cross-sectional study of 343 nurses was conducted in public hospitals of Addis Ababa in 2012. Data were collected by pretested and self-administered questionnaires using a nursing stress scale. One hundred twenty-one (37.8%) (95% confidence interval: 34.3 to 39.1) nurses reported experiencing occupational stress. Significant associations were found between nurses' stress and gender, work shift, illness, marital status, and worksite or unit. Prevalence of work-related stress was higher than expected and opportunities exist for stake holders to design stress reduction and management programs for nurses. Copyright 2014, SLACK Incorporated.

Although data from longitudinal studies are sparse, effort-reward imbalance (ERI) seems to affect work ability. However, the potential pathway from restricted work ability to ERI must also be considered. Therefore, the aim of our study was to analyse cross-sectional and longitudinal associations between ERI and work ability and vice versa. Data come from the Second German Sociomedical Panel of Employees. Logistic regression models were estimated to determine cross-sectional and longitudinal associations. The sample used to predict new cases of poor or moderate work ability was restricted to cases with good or excellent work ability at baseline. The sample used to predict new cases of ERI was restricted to persons without ERI at baseline. The cross-sectional analysis included 1501 full-time employed persons. The longitudinal analyses considered 600 participants with good or excellent baseline work ability and 666 participants without baseline ERI, respectively. After adjustment for socio-demographic variables, health-related behaviour and factors of the work environment, ERI was cross-sectionally associated with poor or moderate work ability (OR = 1.980; 95% CI: 1.428 to 2.747). Longitudinally, persons with ERI had 2.1 times higher odds of poor or moderate work ability after one year (OR = 2.093; 95% CI: 1.047 to 4.183). Conversely, persons with poor or moderate work ability had 2.6 times higher odds of an ERI after one year (OR = 2.573; 95% CI: 1.314 to 5.041). Interventions that enable workers to cope with ERI or address indicators of ERI directly could promote the maintenance of work ability. Integration management programmes for persons with poor work ability should also consider their psychosocial demands.

This cross-sectional multilevel study aimed to investigate the relationship between improvement of the work environment and work-related stress in a nationally representative sample in Japan. The study was based on a national survey that randomly sampled 1745 worksites and 17,500 nested employees. The survey asked the worksites whether improvements of the work environment were conducted; and it asked the employees to report the number of work-related stresses they experienced. Multilevel multinominal logistic and linear regression analyses were conducted. Improvement of the work environment was not significantly associated with any level of work-related stress. Among men, it was significantly and negatively associated with the severe level of work-related stress. The association was not significant among women. Improvements to work environments may be associated with reduced work-related stress among men nationwide in Japan.
Resonance analysis and evaluation of the 235U neutron induced cross sections

Neutron cross sections of fissile nuclei are of considerable interest for the understanding of parameters such as resonance absorption, resonance escape probability, resonance self-shielding,and the dependence of the reactivity on temperature. In the present study, new techniques for the evaluation of the 235 U neutron cross sections are described. The Reich-Moore formalism of the Bayesian computer code SAMMY was used to perform consistent R-matrix multilevel analyses of the selected neutron cross-section data. The Δ 3 -statistics of Dyson and Mehta, along with high-resolution data and the spin-separated fission cross-section data, have provided the possibility of developing a new methodology for the analysis and evaluation of neutron-nucleus cross sections. The results of the analysis consists of a set of resonance parameters which describe the 235 U neutron cross sections up to 500 eV. The set of resonance parameters obtained through a R-matrix analysis are expected to satisfy statistical properties which lead to information on the nuclear structure. The resonance parameters were tested and showed good agreement with the theory. It is expected that the parametrization of the 235 U neutron cross sections obtained in this dissertation represents the current state of art in data as well as in theory and, therefore, can be of direct use in reactor calculations. 44 refs., 21 figs., 8 tabs
Data interpretation, objective evaluation procedures and mathematical techniques for the evaluation of energy-dependent ratio, shape and cross section data

The evaluation of several energy-dependent neutron cross sections which are of importance for practical applications is considered. The evaluation process is defined as the procedure which is used to derive the best knowledge of these cross sections based on the available direct experimental data information, and, using theoretical models, on the auxiliary data base. The experimental data base represents a multiple overdetermination of the unknown cross sections with various correlations between the measured values. Obtaining the least-squares estimator is considered as the standard mathematical procedure to derive a consistent set of evaluated cross section values. Various approximations made in order to avoid the monstrous system of normal equations are considered and the feasibility of the exact solution is demonstrated. The variance-covariance of the result, its reliability and the improvements obtained in iterative steps are discussed. Finally, the inclusion of auxiliary, supplementary information is considered. 45 references

The Technical Support Section (TSS) of the Instrumentation and Controls (I and C) Division of Oak Ridge National Laboratory (ORNL) provides technical services such as fabrication, modification, installation, calibration, operation, repair, and preventive maintenance of instruments and other related equipment. Because the activities and priorities of TSS must be adapted to the technical support needs of ORNL, the TSS Annual Work Plan is derived from, and is driven directly by, current trends in the budgets and activities of each ORNL division for which TSS provides support. Trends that will affect TSS planning during this period are reductions in the staffing levels of some R and D programs because of attrition or budget cuts. TSS does not have an annual budget to cover operating expenses incurred in providing instrument maintenance support to ORNL. Each year, TSS collects information concerning the projected funding levels of programs and facilities it supports. TSS workforce and resource projections are based on the information obtained and are weighted depending on the percentage of support provided to that division or program. Each year, TSS sets the standard hourly charge rate for the following fiscal year. The Long-Range Work Plan is based on estimates of the affects of the long-range priorities and directions of the Laboratory. Proposed new facilities and programs provide additional bases for long-range planning. After identifying long-range initiatives, TSS planning includes future training requirements, reevaluation of qualifications for new hires, and identification of essential test equipment that will be needed for new work.

BACKGROUND Numerically, nurses represent the largest healthcare profession, thus setting norms for the quality and safety of direct patient care. Evidence of a global shortage of nurses in all clinical practice settings across different healthcare systems and countries has been documented. The aims of the present study were: (1) to assess work environments in a sample of German transplant nurses, and (2) to compare their statements with a US-based sample. MATERIAL AND METHODS In a cross-sectional study, 181 transplant nurses from 16 German transplant centers provided information on their work environments. The translated version of the Job Design (JD) and Job Satisfaction (JS) survey showed satisfactory internal consistency for the JD (0.78) and JS (0.93) subscales. German nurses' work environments were compared with 331 transplant nurses from the US. RESULTS The majority of transplant nurses were female (81.8%), 55.4% were age 21-40 years, and 78.1% were employed full-time. German (versus US) transplant nurses reported their job design to be best for 'skill varieties' (p≤0.0002), and worst for 'autonomy' (p≤0.01). Job satisfaction was best with 'opportunities for autonomy and growth' (p≤0.0001), and 'pay and benefits' (p≤0.0001) was lowest. A higher professional degree (OR 1.57; p≤0.03; 95% CI 1.19-2.86), and longer time in transplant (OR 1.24; p≤0.001; 95% CI 1.11-1.38) showed a positive impact on German transplant nurses' perceptions of 'job satisfaction'. Nurses with time-dependent working contracts perceived more stress negatively affecting job satisfaction (OR 1.13; p≤0.009; 95% CI 1.02-12.82). CONCLUSIONS German specialty nurses working in the field of solid organ transplantation rate their work environments with respect to job design and job satisfaction as satisfactory. Institutions' investment into satisfactory nurse work environments and specializing nurses might increase the quality of care, thus improving patient outcomes.

Full Text Available CONTEXT AND OBJECTIVE: Mouth breathing syndrome is very common among school-age children, and it is possibly related to learning difficulties and low academic achievement. In this study, we investigated working memory, reading comprehension and arithmetic skills in children with nasal and mouth breathing. DESIGN AND SETTING: Analytical cross-sectional study with control group conducted in a public university hospital. METHODS: 42 children (mean age = 8.7 years who had been identified as mouth breathers were compared with a control group (mean age = 8.4 years matched for age and schooling. All the participants underwent a clinical interview, tone audiometry, otorhinolaryngological evaluation and cognitive assessment of phonological working memory (numbers and pseudowords, reading comprehension and arithmetic skills. RESULTS: Children with mouth breathing had poorer performance than controls, regarding reading comprehension (P = 0.006, arithmetic (P = 0.025 and working memory for pseudowords (P = 0.002, but not for numbers (P = 0.76. CONCLUSION: Children with mouth breathing have low academic achievement and poorer phonological working memory than controls. Teachers and healthcare professionals should be aware of the association of mouth breathing with children's physical and cognitive health.

Full Text Available Background: Epidemiological studies have shown that employees working with visual display units (VDU are more likely to complain about musculoskeletal disorders (MSDs. The aim of this study has been to evaluate associations among MSDs and individuals and work-related factors. Material and Methods: A total of 1032 VDU workers were assessed about their personal (i.e., age, working history, smoking history, physical activity and work-related factors (i.e., predominant job tasks performed, work posture. Work environment was evaluated regarding fulfillment of the standard ISO 9241-5:1998. The investigation required a direct observation of participants (in order to accurately assess the prevalence of MSDs and workstations. Adjusted odds ratios (ORa were calculated by means of the logistic regression model. Results: Prevalence of MSDs was relatively high (53%. In general, MSDs were significantly associated with female sex (OR = 2.832, 95% confidence interval (CI: 2.178–3.683, age ≥ 50 years old (OR = 2.231, 95% CI: 1.236–4.026, longer exposure to VDU, both as working history (10–14 years: OR = 1.934, 95% CI: 1.301–2.875; ≥ 15 years: OR = 2.223, 95% CI: 1.510–3.271 and working time (30–39 h/week: OR = 1.537, 95% CI: 1.087–2.273. Inappropriate workstation design was confirmed by the multivariate analysis as a risk factor for MSDs (ORa = 2.375, 95% CI: 1.124–5.018. Conclusions: Musculoskeletal disorders were significantly associated with individual factors as well as characteristics of work environment. An appropriate design of workstations may significantly reduce their prevalence amongst VDU workers. Med Pr 2016;67(6:707–719

New evaluated neutron cross section libraries for the GEANT4 code

International Nuclear Information System (INIS)

Mendoza, E.; Cano-Ott, D.; Guerrero, C.; Capote, R.

2012-04-01

The so-called High Precision neutron physics model implemented in the GEANT4 simulation package allows simulating the transport of neutrons with energies up to 20 MeV. It relies on the G4NDL cross section libraries, prepared by the GEANT4 collaboration from evaluated cross section files and distributed freely together with the code. Even though the performance of the G4NDL library has been improved over the time, users running complex simulations which involve the transport of neutrons do need more flexibility, in particular when assessing the uncertainties in the simulation results due to the neutron (and hence the nuclear) data library used. For this reason, a software tool has been developed for transforming any evaluated neutron cross section library in the ENDF-6 format into the G4NDL format. Furthermore, eight different releases of ENDF-B, JEFF, JENDL, CENDL and BROND national libraries have been translated into the G4NDL format and are distributed by the IAEA nuclear data service at www-nds.iaea.org/geant4. In this way, GEANT4 users have access to the complete list of standard evaluated neutron data libraries when performing Monte Carlo simulations with GEANT4. Consistency checks and a first validation of the libraries have been made following the methods described in this report. (author)
Planning and Evaluating Educational Work in Slovene Preschools

Full Text Available The present article examines the changes in Slovene preschools subsequent to Slovenia’s independence in 1991. In the socialist period, the national education programme for preschools was highly structured, goaland content-oriented and subject to schoolization. The Curriculum for Preschools (1999 brought conceptual changes towards education “based on the child” and the process approach, as well as giving more autonomy to preschool teachers and their assistants. In the empirical study, we examine changes in planning and evaluating educational work compared to the past. The results show that the majority of professional workers have reduced the high level of structure and rigidity in planning, and that there is better cooperation between preschool teachers and teachers’ assistants. Unlike in the past, most professional workers regularly evaluate their educational work. As the data was gathered in two phases, before and after the training of professional workers in the Reggio Emilia concept, we also search for the (probably indirect influencesof this training. We conclude that after the training the participation of children in planning and evaluating educational work is higher.

The Section is concerned with preparation of environmental statements and assessments and development of assessment methodologies for energy technologies. During 1976, activities involved nuclear, fossil, and geothermal energy; this work was supported by the U.S.Army, HUD, US ERDA, and US NRC. Two special studies--one on the effects of power plant intake structures on fish impingement and another on multiple uses of cooling lakes--were completed and should serve as references for future analyses. Two research projects sponsored by NRC--the Unified Transport Approach (UTA) to Power Plant Assessment and the Environmental Monitoring Data Evaluation Study--were continued. The purpose of the UA program is to develop fast-transient, one- and two-dimensional transport models for estimating thermal, radiological, chemical, and biological impacts in complicated water bodies. The impact of public use of various products that contain radioactive isotope is being evaluated. The Environmental Impact Sections assistance to NRC expanded to include assessments of fuel-fabrication facilities being considered for relicensing and two uranium in-situ solution mining facility proposals. The work for HUD comprises an assessment of the first application of MIUS in a new town development. A generic environmental statement was prepared and an environmental monitoring program for the facility was designed
Evaluating Scientific Work by Means of Diffusion

Directory of Open Access Journals (Sweden)

Dan Ophir

2013-10-01

Full Text Available There are two approaches for evaluating scientific papers. The classic way is to choose well established representatives of the specific scientific community and have them evaluate their colleague's work. The other method of evaluation, the so called peer-evaluation method, is where peers (famous or otherwise of the author evaluate the paper. Peer-evaluation resembles the diffusion process in which a new substance spreads out to the whole solution. Similarly the new author and article are diffused among the scientific community, smoothing the level for accepting scientific papers. Using the classic-evaluation system of accepting new papers, the average starting scientists writes their first number of articles as collaborators with a renowned scientist, thus gradually building up their image. Only afterwards do these authors dare to independently publish. What are the pros and cons of both these types of scientific article evaluations?
Working memory: a proposal for child evaluating

Full Text Available The working memory is a system with limited capacity which allows the temporary storage and manipulation of information to cognitive complex abilities like language, learning and reasoning. This study has as the objective present the construction, the adaptation and the evaluation of four psycholinguistics working memory tests in Brazilian Portuguese that were based in the English battery of tests Memory Test Battery For Children. The tests adapted were applied in a pilot investigation in a group of 15 children with learning school difficulties and compared to a group of 15 children with normal development. The adaptation of the tests was developed in the E-Prime v2.0 Professional® software. The four psycholinguistic tests access the simultaneous storage and processing capacities of information in general domain, as also specific for language information. The results suggest that the four tests are sensible instruments to detect possible difficulties in the working memory processing in children, because they could identify the different performances between the two groups in a statistical analysis. The tests developed perfectly attended their aims for evaluation and can contribute in a near future for other studies with a greater number of subjects, providing a more concrete and evidences of working memory development in children.

Given the role nurse faculty have in educating nurses, little is known about what influences their intention to remain employed (ITR) in academic settings. Findings from a nurse faculty survey administered to test a conceptual model of factors hypothesized as influencing nurse faculty ITR are reported. A cross-sectional survey design was employed. We included colleges and universities in Ontario, Canada. The population of Ontario nurse faculty who reported being employed as nurse faculty with the College of Nurses of Ontario (Canada) was included. Of the 1328 nurse faculty who were surveyed, 650 participated. Participants completed a questionnaire with measures of work, work environment, job satisfaction, burnout and ITR. Regression analyses were conducted to test the model. Ten of 26 independent variables explained 25.4% of variance in nurse faculty ITR for five years. These variables included: proximity to retirement, quality of relationships with colleagues, being employed full time, having dependents, satisfaction with work-life balance, quality of education, satisfaction with job status, access to financial support for education from organization, access to required human resources and being unionized. Although not all influencing factors are modifiable, academic leadership should develop strategies that encourage nurse faculty ITR. Strategies that support collegial relationships among faculty, increase the number of full time positions, promote work-life balance, engage faculty in assessing and strengthening education quality, support faculty choice between full-time and part-time work, and ensure adequate human resources required to teach effectively will lead to heightened nurse faculty ITR. © 2013.
Methods and procedures for evaluation of neutron-induced activation cross sections

International Nuclear Information System (INIS)

Gardner, M.A.

1981-09-01

One cannot expect measurements alone to supply all of the neutron-induced activation cross-section data required by the fission reactor, fusion reactor, and nuclear weapons development communities, given the wide ranges of incident neutron energies, the great variety of possible reaction types leading to activation, and targets both stable and unstable. Therefore, the evaluator must look to nuclear model calculations and systematics to aid in fulfilling these cross-section data needs. This review presents some of the recent developments and improvements in the prediction of neutron activation cross sections, with specific emphasis on the use of empirical and semiempirical methods. Since such systematics require much less nuclear informaion as input and much less computational time than do the multistep Hauser-Feshbach codes, they can often provide certain cross-section data at a sufficient level of accuracy within a minimum amount of time. The cross-section information that these systematics can and cannot provide and those cases in which they can be used most reliably are discussed

Full Text Available Abstract: According to the Work-Home Resources Model, contextual family resources increase personal resources, which, in turn, improve work outcomes. The present study investigated the direct effects of two contextual family resources (work- family enrichment and perceived social support from family and one personal resource (core self-evaluations on a work outcome (flourishing at work. The mediational role of core self-evaluations in these relationships was also investigated. The sample was composed of 519 Brazilian psychologists of both sexes. The Structural Equation Modeling showed that the contextual family resources and the personal resource predicted flourishing at work and that core self-evaluations mediated the relationships between contextual resources and flourishing at work. It was concluded that the acquisition of resources within the family and the positive evaluation of one’s own life can promote flourishing at work.

The purpose of this study was to explore the associations between workplace bullying, the characteristics of workplace bullying, and sleep disturbances in a large sample of employees of the French working population. Workplace bullying, evaluated using the validated instrument developed by Leymann, and sleep disturbances, as well as covariates, were measured using a self-administered questionnaire. Covariates included age, marital status, presence of children, education, occupation, working hours, night work, physical and chemical exposures at work, self-reported health, and depressive symptoms. Statistical analysis was performed using logistic regression analysis and was carried out separately for men and women. General working population. The study population consisted of a random sample of 3132 men and 4562 women of the working population in the southeast of France. Workplace bullying was strongly associated with sleep disturbances. Past exposure to bullying also increased the risk for this outcome. The more frequent the exposure to bullying, the higher the risk of experiencing sleep disturbances. Observing someone else being bullied in the workplace was also associated with the outcome. Adjustment for covariates did not modify the results. Additional adjustment for self-reported health and depressive symptoms diminished the magnitude of the associations that remained significant. The prevalence of workplace bullying (around 10%) was found to be high in this study as well was the impact of this major job-related stressor on sleep disturbances. Although no conclusion about causality could be drawn from this cross-sectional study, the findings suggest that the contribution of workplace bullying to the burden of sleep disturbances may be substantial.

The authors describe a method based on the reduction method for the evaluation of photonuclear reaction cross-sections obtained under conditions where there are large systematic uncertainties (different instrumental functions, calibration and normalization errors). The evaluation method involves using the actual instrumental function (photon spectrum) of each individual experiment to reduce the data to a representation generated by an instrumental function of better quality. The objective is to find the most reasonably achievable monoenergetic representation of the information on the reaction cross-section derived from the results of various experiments and to take into account the calibration and normalization errors in these experiments. The method was used to obtain the evaluated total photoneutron reaction cross-section (γ,xn) for a large number of nuclei. Data obtained for 16 O and 208 Pb are presented.

Full Text Available This paper shares the details of an evaluation plan from an interdisciplinary climate change project that developed decision support tools (DSTs for agricultural advisors and farmers. It showcases how evaluation enhanced the project work by providing opportunities for the team to reflect on and use data to improve performance. The plan included both formative and summative approaches, team member interviews to assess team functioning, usability testing of DSTs, outreach and marketing campaign evaluation. Outreach evaluation included surveying those reached, monitoring project website traffic, and tracking and mapping outreach details. Marketing evaluation included pre-testing campaign materials, assessing open and click rates of email campaign, and monitoring associated traffic to website. The Useful to Usable (U2U team was generally high functioning, but team interviews allowed the evaluators and leaders to discern factors that were influencing intended outcomes, respond to needs, assign resources, and catalyze activities that were crucial in shaping the outcomes. Usability testing surfaced issues related to default values and search and help features that were addressed by the team and resulted in improved usability. Outreach evaluation found geographic and methodological gaps that were filled, resulting in more target audiences reached and more effective methods used (e.g., hands-on events. Marketing evaluation allowed for improving contact lists over time and improving campaign messaging before deployment. Evaluators and project leaders working on similar projects may adapt or utilize methods detailed in this paper, along with the recommendations, while designing and implementing improvement-oriented evaluation plans.

To identify and explore the factors promoting sickness presenteeism among offshore catering section workers. Twenty men and women, working in the offshore catering section onboard three offshore oil and gas production platforms on the Norwegian Continental Shelf, participated in three focus groups. Data from the focus groups were analysed according to a phenomenological approach, and supported by theories on presenteeism. The results show that the decision to attend work despite illness, first and foremost, was based on the severity of the health complaint. Other factors identified were; the individual's location once the health complaint occurred, job satisfaction, the norms of the team, and experiences of how company policies on sickness absenteeism were implemented by the catering section leaders. Offshore working conditions may promote sickness presenteeism. The factors promoting sickness presenteeism onboard the platforms reflected experiences of a healthy work environment.

Full Text Available Objectives: This study aimed at investigating cross-sectional relationships between psychosocial characteristics of work and presenteeism in a sample of Belgian middle-aged workers. Material and Methods: Data were collected from 1372 male and 1611 female workers in the Belstress III study. Psychosocial characteristics assessed by the use of self-administered questionnaires were: job demands, job control, social support, efforts, rewards, bullying, home-to-work conflict and work-to-home conflict. Presenteeism was measured using a single item question, and it was defined as going to work despite illness at least 2 times in the preceding year. Logistic regression models were used to investigate the relationship between psychosocial characteristics and presenteeism, while adjusting for several socio-demographic, health-related variables and neuroticism. An additional analysis in a subgroup of workers with good self-rated health and low neuroticism was conducted. Results: The prevalence of presenteeism was 50.6%. Overall results, adjusted for major confounders, revealed that high job demands, high efforts, low support and low rewards were associated with presenteeism. Furthermore, a significant association could be observed for both bullying and work-to-home conflict in relation to presenteeism. The subgroup analysis on a selection of workers with good self-rated health and low neuroticism generally confirmed these results. Conclusions: Both job content related factors as well as work contextual psychosocial factors were significantly related to presenteeism. These results suggest that presenteeism is not purely driven by the health status of a worker, but that psychosocial work characteristics also play a role.

Objective It is well documented that both work stress and work motivation are key determinants of job satisfaction. The aim of this study was to examine levels of work stress and motivation and their contribution to job satisfaction among community health workers in Heilongjiang Province, China. Design Cross-sectional survey. Setting Heilongjiang Province, China. Participants The participants were 930 community health workers from six cities in Heilongjiang Province. Primary and secondary outcome measures Multistage sampling procedures were used to measure socioeconomic and demographic status, work stress, work motivation and job satisfaction. Logistic regression analysis was performed to assess key determinants of job satisfaction. Results There were significant differences in some subscales of work stress and work motivation by some of the socioeconomic characteristics. Levels of overall stress perception and scores on all five work stress subscales were higher in dissatisfied workers relative to satisfied workers. However, levels of overall motivation perception and scores on the career development, responsibility and recognition motivation subscales were higher in satisfied respondents relative to dissatisfied respondents. The main determinants of job satisfaction were occupation; age; title; income; the career development, and wages and benefits subscales of work stress; and the recognition, responsibility and financial subscales of work motivation. Conclusions The findings indicated considerable room for improvement in job satisfaction among community health workers in Heilongjiang Province in China. Healthcare managers and policymakers should take both work stress and motivation into consideration, as two subscales of work stress and one subscale of work motivation negatively influenced job satisfaction and two subscales of work motivation positively influenced job satisfaction.

Musculoskeletal pain and stress-related disorders are leading causes of impaired work ability, sickness absences and disability pensions. However, knowledge about the combined detrimental effect of pain and stress on work ability is lacking. This study investigates the association between pain in the neck-shoulders, perceived stress, and work ability. In a cross-sectional survey at a large pharmaceutical company in Denmark 473 female laboratory technicians replied to questions about stress (Perceived Stress Scale), musculoskeletal pain intensity (scale 0-10) of the neck and shoulders, and work ability (Work Ability Index). General linear models tested the association between variables. In the multi-adjusted model, stress (p pain (p stress by pain interaction (p = 0.32). Work ability decreased gradually with both increased stress and pain. Workers with low stress and low pain had the highest Work Ability Index score (44.6 (95% CI 43.9-45.3)) and workers with high stress and high pain had the lowest score (32.7 (95% CI 30.6-34.9)). This cross-sectional study indicates that increased stress and musculoskeletal pain are independently associated with lower work ability in female laboratory technicians.

Healthcare providers being over-worked and under staffed are prone to poor mental health. Unhealthy work place compounds it further. This study was aimed at to assess the mental health status of a medical university employee with special reference to work place stressors. A cross-sectional study was designed and carried out at a Rural Health University. Both the General Health Questionnaire (GHQ)-12 and Holmes-Rahe Scale were used to evaluate 406 participants. Multivariate analysis, correlation, and ANOVA by SPSS 11.0. The minimum age of the participant was 19 years and the maximum 64 years, with an average age at 35.09 years. On the GHQ scale 239(58.9%) recorded psychiatric morbidity out of which 201(49.5%) had moderate and 38(9.3%) severe morbidity. Doctors were the highest stressed group (P ≤ 0.04). Prominent work environmental stressors were poor departmental reorganization, lack of cohesiveness in department, difficult superiors and juniors (P ≤ 0.001, Pearson correlation). Stressors associated with work organization and work nature were: noninvolvement in departmental decision making and lack of proper feedback; along with; work load, lack of clarity in job, and a erratic work schedule (P ≤ 0.001 on Pearson correlation). Harassment, favoritism, discrimination, and lack of self-expression (P ≤ 0.003) were other factors responsible for work dissatisfaction. A high stress level was detected in the study population. The principal stressors were work environment related. Poor work culture was found to lead to job dissatisfaction among majority.

Purpose The revised version of the Work Ability Survey (WAS-R) assesses work ability on several sub-scales at the intersection of personal and organizational capacity, thus adding to the measurement of work ability by integrating the holistic model. It, therefore, improves on two features of the current standard measurement tool of work ability, the Work Ability Index (WAI): (1) a ceiling effect and (2) limited detail due to a focus on physical health and personal capacity. Method In two samples (n 1 = 1093, n 2 = 359), psychometric properties and the structure of the WAS-R were analyzed. To evaluate construct validity, inter-correlations of the WAS-R and WAI, sickness absence, expected and desired retirement age, and post-retirement work intention were calculated. Results The WAS-R was found to be distributed closer to normality than the WAI. The structural analyses yielded acceptable results for the hypothesized model. The WAS-R was adequately correlated with the WAI, negatively with sickness absence, and positively with desired retirement age. Conclusions The WAS-R extends the measurement of work ability, reflecting organizations' work demands. Its broad sub-scales lead to high acceptance of the results within the participating companies. In particular, the organizational capacity scales can be used to guide interventions aiming at organizational characteristics to improve work ability.

Methods Questionnaires, measuring working conditions, work-family conflict, sleep disturbances and depressive symptoms were collected from 397 nurses at a not-for-profit community hospital in the north-eastern United States. Results We observed a significant association between work-family conflict and depressive symptoms (β = 2.22, p conflict into depressive symptoms. Implications Evidence-based interventions to promote healthy sleep practices should be evaluated for their effectiveness in addressing the impact of work-family conflict on mental health. Organizations should include sleep education and training as a component of workplace health promotion and employee assistance programmes to mitigate the effect of work-family conflict and promote overall health in nurses. © 2017 John Wiley & Sons Ltd.

When the interplay between work and private life does not function correctly (work-home conflict), this constitutes a well-known risk factor for poorer health, increased absenteeism and lower work performance. Information about influencing factors of work-home conflict is therefore indispensable in order to avoid it. In this study, we analyse whether a good working atmosphere that fosters mutual trust, support and a 'sense of unity' (organizational social capital) can reduce an employee's conflict between work and private life. This study investigates the link between organizational social capital and work-home conflict in health professionals. This issue was investigated using a cross-sectional study conducted in 2013. Data from questionnaires completed by physicians and nurses (n=1733) were linked with structural data from 66 neonatal intensive care units in Germany. Using multi-level analyses, we investigated associations between organizational social capital at the ward level and work-home conflict at the level of individual employees, taking into account additional structural and individual characteristics. Employees on wards with greater social capital reported significantly less work-home conflict. Our results support the hypothesis that organizational social capital is an important collective resource. As such, more attention should be given to establishing a good working atmosphere that fosters mutual trust, support and a 'sense of unity', and this should be encouraged in a targeted fashion.

When the plan of decommissioning such as nuclear fuel cycle facilities and small-scale research reactors is examined, it is necessary to select the technology and the process of the work procedure, and to optimize the index (such as the radiation dose, the cost, amount of the waste, the number of workers, and the term of works, etc.) concerning dismantling the facility. In our waste management section, Development of the decommissioning management system, which is called 'DECMAN', for the support of making the decommissioning plan is advanced. DECMAN automatically calculates the index by using the facility data and dismantling method. This paper describes the remodeling of program to the personal computer and the system verification by evaluation of real work (Dismantling of the liquor dissolver in the old JOYO Waste Treatment Facility (the old JWTF), the glove boxes in Deuterium Critical Assembly (DCA), and the incinerator in Waste Dismantling Facility (WDF)). The outline of remodeling and verification is as follows. (1) Additional function: 1) Equipment arrangement mapping, 2) Evaluation of the radiation dose by using the air dose rate, 3) I/O of data that uses EXCEL (software). (2) Comparison of work amount between calculation value and results value: The calculation value is 222.67man·hour against the result value 249.40 man·hour in the old JWTF evaluation. (3) Forecast of accompanying work is predictable to multiply a certain coefficient by the calculation value. (4) A new idea that expected the amount of the work was constructed by using the calculation value of DECMAN. (author)

It is well documented that both work stress and work motivation are key determinants of job satisfaction. The aim of this study was to examine levels of work stress and motivation and their contribution to job satisfaction among community health workers in Heilongjiang Province, China. Cross-sectional survey. Heilongjiang Province, China. The participants were 930 community health workers from six cities in Heilongjiang Province. Multistage sampling procedures were used to measure socioeconomic and demographic status, work stress, work motivation and job satisfaction. Logistic regression analysis was performed to assess key determinants of job satisfaction. There were significant differences in some subscales of work stress and work motivation by some of the socioeconomic characteristics. Levels of overall stress perception and scores on all five work stress subscales were higher in dissatisfied workers relative to satisfied workers. However, levels of overall motivation perception and scores on the career development, responsibility and recognition motivation subscales were higher in satisfied respondents relative to dissatisfied respondents. The main determinants of job satisfaction were occupation; age; title; income; the career development, and wages and benefits subscales of work stress; and the recognition, responsibility and financial subscales of work motivation. The findings indicated considerable room for improvement in job satisfaction among community health workers in Heilongjiang Province in China. Healthcare managers and policymakers should take both work stress and motivation into consideration, as two subscales of work stress and one subscale of work motivation negatively influenced job satisfaction and two subscales of work motivation positively influenced job satisfaction.

Utilization of cross-section covariance data in FBR core nuclear design and cross-section adjustment

International Nuclear Information System (INIS)

Ishikawa, Makoto

1994-01-01

In the core design of large fast breeder reactors (FBRs), it is essentially important to improve the prediction accuracy of nuclear characteristics from the viewpoint of both reducing cost and insuring reliability of the plant. The cross-section errors, that is, covariance data are one of the most dominant sources for the prediction uncertainty of the core parameters, therefore, quantitative evaluation of covariance data is indispensable for FBR core design. The first objective of the present paper is to introduce how the cross-section covariance data are utilized in the FBR core nuclear design works. The second is to delineate the cross-section adjustment study and its application to an FBR design, because this improved design method markedly enhances the needs and importance of the cross-section covariance data.

The application of ethical principles within the teaching profession and nursing practice forms the core of the nurse educator's professional ethics. However, research focusing on the professional ethics of nurse educators is scarce. To describe ethical principles and issues relating to the work of nurse educators from the perspectives of both nurse educators themselves and nursing students. A descriptive study using cross-sectional data and content analysis. Nursing education program involving students from nine polytechnics in Finland. Nursing students (n=202) and nurse educators (n=342). Data were derived from an online survey, with two open-ended questions: Nursing students and nurse educators were asked to name the three main ethical principles that guide the work of nurse educators and also to describe ethical issues involved in the work. Students most often named professionalism, justice, and equality as the main ethical principles for a nurse educator. Nurse educators considered justice, equality, and honesty as the main ethical principles. The content analysis showed that professionalism and the relationship between educator and student were the key categories for ethical issues as perceived by nursing students. Nursing students most often identified inequality between the nurse educator and nursing student as the ethical issue faced by the nurse educator. Nursing students and nurse educators differed somewhat both in their views of the ethical principles guiding an educator's work and in the ethical issues arising in the work.

Work aggravated asthma (WAA), asthma made worse by but not caused by workplace exposures, can have a negative impact on personal, social, financial and societal costs. There is limited data on prevalence levels of WAA in Great Britain (GB). The objective of this study was to estimate the prevalence of WAA in GB, and to assess its potential causes.Materials and methodsA cross-sectional postal questionnaire study was carried out. A total of 1620 questionnaires were sent to three populations of adults with asthma. The questionnaire recorded; demographic details, current job, self-reported health status, presence of asthma and respiratory symptoms, duration and severity of symptoms and medication requirements. Questions relating to work environment and employers' actions were included, and each participant completed an assessment of health-related quality of life using the EuroQol Research Foundation EQ-5D. There were 207 completed questionnaires; response rates were 6% primary care, 45% secondary care and 71% Asthma UK. This represented a 13% overall response rate. Self-reported prevalence of WAA was 33% (95% CI 24.4-41.6%). In all, 19% of workers had changed their job because of breathing problems. Workers with WAA reported higher levels of work-related stress. Quality of life using the EQ-5D utility index was lower in those with WAA. WAA is a common problem in asthmatics in GB. This result is in keeping with international prevalence rates. Further research could assist the understanding of the most significant aggravants to asthma at work and help define appropriate interventions by workplaces.

Hetrick, D.M.; Fu, C.Y.; Larson, D.C.

1982-09-01

Nuclear model codes were used to compute cross sections for neutron-induced reactions on 40 Ca for incident energies from 20 to 40 MeV. The input parameters for the model codes were determined through analysis of experimental data in this energy region. Computed cross sections along with emission spectra for each product were combined into an Evaluated Nuclear Data File (ENDF) using the proposed format for charged-particle reactions. Discussion of the models used, the resulting calculations, and the final evaluated data file are presented

To evaluate the effect of a 1-2 week multiprofessional team assessment, without a real rehabilitation effort, 60 patients suffering from long-standing pain and on long-lasting time on sick leave were studied. A questionnaire concerning their daily activities, quality of life, pain intensity, sick-leave level, and their work state was filled out by all patients before starting the assessment and at a 1-year follow-up. The results from the assessment period and the multiprofessional team decision of the patient's working ability were compared with the actual working rate after 1 year. The follow-up showed a significant reduction of sick leave and a higher level of activity (P work. However, the team evaluation of the patient's work ability did not correlate to predict the actual outcome. The patient's pain intensity, life satisfaction, gender, age, ethnic background, and time absent from work before the start of the evaluation showed no correlation to reduction on time on sickness benefit level. These parameters could not be used as predictors in this study.

Statistical analysis of correlated experimental data and neutron cross section evaluation

International Nuclear Information System (INIS)

Badikov, S.A.

1998-01-01

The technique for evaluation of neutron cross sections on the basis of statistical analysis of correlated experimental data is presented. The most important stages of evaluation beginning from compilation of correlation matrix for measurement uncertainties till representation of the analysis results in the ENDF-6 format are described in details. Special attention is paid to restrictions (positive uncertainty) on covariation matrix of approximate parameters uncertainties generated within the method of least square fit which is derived from physical reasons. The requirements for source experimental data assuring satisfaction of the restrictions mentioned above are formulated. Correlation matrices of measurement uncertainties in particular should be also positively determined. Variants of modelling the positively determined correlation matrices of measurement uncertainties in a situation when their consequent calculation on the basis of experimental information is impossible are discussed. The technique described is used for creating the new generation of estimates of dosimetric reactions cross sections for the first version of the Russian dosimetric file (including nontrivial covariation information)
EVALUATION OF WORKING ABILITY OF THE WORKERS SUFFERING FROM CARDIOVASCULAR DISEASES

Full Text Available Within the disability evaluation process, three different and potentially conflicting roles for the clinician become clear: patient advocate, provider of information, and medical adjudicator. It is important to understand the requirements of each of these roles so that the patient can best be served. The working ability evaluation is a process of numerous examinations, measurements and estimates that are done by a team of medical and other experts. It is utterly unacceptable to think that the opinion about someone’s working ability is given by some individual specialist of any expert domain especially regarding the invalids category since this can lead to either confusion or undesired conflicts between the patient and those who are professionally and legally qualified to evaluate his working ability. In order to carry out the medical part of the expertise for evaluating the working ability it is necessary have an accurate diagnosis of particular disease, an opinion whether the process is define or can be improved by and adequate therapy in addition to the state of morphology and function of all the organs and systems essential for responding to the biological requirements of the working operations at a given job as well as the estimate of the functional ability of the organs or system. The practical evaluation of the working ability also has to include the professional utilization factor, that is, it is necessary to determine the working operations requirements as well as the conditions in which they are performed at a given job. Within the working ability it is necessary to take into consideration the psychosocial structure of the sick person, years of age, qualification and professional degree as well as the society’s position to accept the proposal made by the medical and other experts. In judging the working ability of the patients having a cardiac disease it is indispensable to view every case separately since it always implies its own

Background: Healthcare providers being over-worked and under staffed are prone to poor mental health. Unhealthy work place compounds it further. Aims: This study was aimed at to assess the mental health status of a medical university employee with special reference to work place stressors. Settings and design: A cross-sectional study was designed and carried out at a Rural Health University. Materials and Methods: Both the General Health Questionnaire (GHQ)-12 and Holmes–Rahe Scale were used to evaluate 406 participants. Statistical analysis: Multivariate analysis, correlation, and ANOVA by SPSS 11.0. Results: The minimum age of the participant was 19 years and the maximum 64 years, with an average age at 35.09 years. On the GHQ scale 239(58.9%) recorded psychiatric morbidity out of which 201(49.5%) had moderate and 38(9.3%) severe morbidity. Doctors were the highest stressed group (P ≤ 0.04). Prominent work environmental stressors were poor departmental reorganization, lack of cohesiveness in department, difficult superiors and juniors (P ≤ 0.001, Pearson correlation). Stressors associated with work organization and work nature were: noninvolvement in departmental decision making and lack of proper feedback; along with; work load, lack of clarity in job, and a erratic work schedule (P ≤ 0.001 on Pearson correlation). Harassment, favoritism, discrimination, and lack of self-expression (P ≤ 0.003) were other factors responsible for work dissatisfaction. Conclusions: A high stress level was detected in the study population. The principal stressors were work environment related. Poor work culture was found to lead to job dissatisfaction among majority. PMID:21687380

A high quality of work life (QWL) is a crucial issue for health care facilities to have qualified, dedicated, and inspired employees. Among different specialties in health care settings, nurses have a major share among other health care providers. So, they should experience a better QWL to deliver high-quality holistic care to those who need help. To assess the level of quality of work life and its predictors among nurses working in Hawassa town public health facilities, South Ethiopia. A facility based cross-sectional study was conducted on 253 nurses of two hospitals and nine health centers. The total sample size was allocated to each facility based on the number of nurses in each facility. Data were collected using a structured questionnaire. The interitem consistency of the scale used to measure QWL had Cronbach's alpha value of 0.86. A multinomial logistic regression model was fitted to identify significant predictors of quality of work life using SPSS version 20. The study showed that 67.2% of the nurses were dissatisfied with the quality of their work life. We found that educational status, monthly income, working unit, and work environment were strong predictors of quality of work life among nurses ( p quality of their work life. The findings in this study and studies reported from elsewhere pinpoint that perception of nurses about the quality of their work life can be modified if health care managers are considerate of the key issues surrounding QWL.

Abstract Background Working Health Service Scotland (WHSS) supports the self-employed and employees of small and medium-sized enterprises (SMEs) in Scotland with a health condition affecting their ability to work, who are either absent or at risk of becoming absent due to it. Aims To evaluate the impact on health and work outcomes of WHSS clients over a 4-year period. Methods Data were collected at enrolment, entry, discharge and follow-up at 3 and 6 months after discharge. Clients completed up to three validated health questionnaires at entry and discharge—EuroQol five dimensions (EQ-5D) and visual analogue scale (VAS); Hospital Anxiety and Depression Scale (HADS); and Canadian Occupational Performance Measure (COPM). Results A total of 13463 referrals occurred in the 4-year period; 11748 (87%) were eligible and completed entry assessment and 60% of the latter completed discharge paperwork. The majority of referrals were due to musculoskeletal conditions (84%) while 12% were referred with mental health conditions. Almost a fifth (18%) of cases were absent at entry and back at work at discharge. Work days lost while in WHSS was associated with age, length of absence prior to entering WHSS, primary health condition and time in programme. All health measures showed significant improvements from entry to discharge. Improvement in general health was sustained at 3- and 6-month follow-up. Conclusions The WHSS evaluation findings indicate that participation was associated with positive changes to health and return-to-work. The extent of the positive change in health measures and work ability can be highly important economically for employees and employers. PMID:29390161

The importance of transformational leadership for nurses' well-being is increasingly acknowledged. However, there is a paucity of research examining the mechanisms that may explain the relationships between transformational leadership and nurses' quality of work life. First, to examine two possible psychological mechanisms that link transformational leadership behaviors to nurses' quality of work life. Second, to study the relationship between nurses' quality of work life and their work engagement. Cross-sectional study design. The study took place in 47 different hematology, oncology, and hematology/oncology units in France. Participants were nurses and auxiliary nurses. 343 nurses completed the questionnaire. Surveys were sent to all nurses working in the units. 95% were female, the average age was 36.30 years. Nurses were asked to rate their supervisor's transformational leadership style and their perceptions of distributive and interactional justice in the unit. They were also asked to evaluate their own level of quality of work life and their work engagement. Distributive justice and interactional justice were found to fully mediate the relationship between transformational leadership and nurses' quality of work life. In addition, nurses' quality of work life positively related to their work engagement. Transformational leaders may help ensure nurses' quality of work life which in turn increases their work engagement. These leadership practices are thus beneficial for both employees and organization. Copyright © 2012 Elsevier Ltd. All rights reserved.

Rethinking programme evaluation in health professions education: beyond 'did it work?'.

Haji, Faizal; Morin, Marie-Paule; Parker, Kathryn

For nearly 40 years, outcome-based models have dominated programme evaluation in health professions education. However, there is increasing recognition that these models cannot address the complexities of the health professions context and studies employing alternative evaluation approaches that are appearing in the literature. A similar paradigm shift occurred over 50 years ago in the broader discipline of programme evaluation. Understanding the development of contemporary paradigms within this field provides important insights to support the evolution of programme evaluation in the health professions. In this discussion paper, we review the historical roots of programme evaluation as a discipline, demonstrating parallels with the dominant approach to evaluation in the health professions. In tracing the evolution of contemporary paradigms within this field, we demonstrate how their aim is not only to judge a programme's merit or worth, but also to generate information for curriculum designers seeking to adapt programmes to evolving contexts, and researchers seeking to generate knowledge to inform the work of others. From this evolution, we distil seven essential elements of educational programmes that should be evaluated to achieve the stated goals. Our formulation is not a prescriptive method for conducting programme evaluation; rather, we use these elements as a guide for the development of a holistic 'programme of evaluation' that involves multiple stakeholders, uses a combination of available models and methods, and occurs throughout the life of a programme. Thus, these elements provide a roadmap for the programme evaluation process, which allows evaluators to move beyond asking whether a programme worked, to establishing how it worked, why it worked and what else happened. By engaging in this process, evaluators will generate a sound understanding of the relationships among programmes, the contexts in which they operate, and the outcomes that result from them

The purpose of this study was to examine the healing period of incision scar in myometrial wall and the normal pelvis after cesarean sections by means of MRI. In this study 17 voluntary women were examined after their first delivery with cesarean section in the early postpartum period (first 5 days), and following this, three more times in 3-month intervals. The MRI examinations were performed on a 1.0-T system (Magnetom, Siemens, Erlangen, Germany), and sagittal T1-weighted (550/17 TR/TE) and T2-weighted (2000/80 TR/TE) spin-echo (SE) images of the pelvis were obtained. During follow-up examinations incision scar tissues lost their signals within the first 3 months on both SE sequences, and little alteration was observed in the subsequent tests. Zonal anatomy of the uterus reappeared completely 6 months after cesarean sections. The time for the involution of the uterus was independent of the zonal anatomy recovery, and the maximum involution was inspected within the first 3 months. In conclusion, the maturation time of myometrial scar tissue in uncomplicated cesarean sections, which can be evaluated by the signal alterations in MRI, is approximately 3 months, whereas the complete involution and the recovery of the zonal anatomy need at least 6 months.

2000-01-01

Neutron cross section evaluations of the fission-product isotopes, 95 Mo, 99 Tc, 101 Ru, 103 Rh, 105 Pd, 109 Ag, 131 Xe, 133 Cs, 141 Pr, 141 Nd, 147 Sm, 149 Sm, 150 Sm, 151 Sm, 152 Sm, 153 Eu, 155 Gd, and 157 Gd were carried out below the fast neutron energy region within the framework of the BNL-KAERI international collaboration. In the thermal energy region, the energy dependence of the various cross-sections was calculated by applying the multi-level Breit-Wigner formalism. In particular, the strong energy dependence of the coherent scattering lengths of 155 Gd and 157 Gd were determined and were compared with recent calculations of Lynn and Seeger. In the resonance region, the recommended resonance parameters, reported in the BNL compilation, were updated by considering resonance parameter information published in the literature since 1981. The s-wave and, if available, p-wave reduced neutron widths were analyzed in terms of the Porter-Thomas distribution to determine the average level spacings and the neutron strength functions. Average radiative widths were also calculated from measured values of resolved energy resonances. The average resonance parameters determined in this study were compared with those in the BNL and other compilations, as well as the ENDF/B-VI, JEF-2.2, and JENDL-3.2 data libraries. The unresolved capture cross sections of these isotopes, computed with the determined average resonance parameters, were compared with measurements, as well as the ENDF/B-VI evaluations. To achieve agreement with the measurements, in a few cases minor adjustments in the average resonance parameters were made. Because of astrophysical interest, the Maxwellian capture cross sections of these nuclides at a neutron temperature of 30 keV were computed and were compared with other compilations and evaluations
The Meaning and Measurement of Work Fatigue: Development and Evaluation of the Three-Dimensional Work Fatigue Inventory (3D-WFI)

Frone, Michael R.; Tidwell, Marie-Cecile O.

2015-01-01

Although work fatigue represents an important construct in several substantive areas, prior conceptual definitions and measures have been inadequate in a number of ways. The goals of the present study were to develop a conceptual definition and outline the desirable characteristics of a work fatigue measure; briefly examine several prior measures of work fatigue-related constructs; and develop and evaluate a new measure of work fatigue. The Three-Dimensional Work Fatigue Inventory (3D-WFI) provides separate and commensurate assessments of physical, mental, and emotional work fatigue. Results from a pilot study (N = 207) and a broader evaluative study of U.S. wage and salary workers (N = 2,477) suggest that the 3D-WFI is psychometrically sound and evinces a meaningful pattern of relations with variables that comprise the nomological network of work fatigue. As with all new measures, additional research is required to evaluate fully the utility of the 3D-WFI in research on work fatigue. PMID:25602275

Women with fibromyalgia (FM) describe great difficulties in managing work. Reported work ability in women with FM varies from 34 to 77 percent in studies from different countries. Many factors are suggested to affect the ability to work in women with FM, including pain, fatigue, impaired physical capacity and activity limitations. However, it is difficult to define to which extent symptom severity can be compatible with work. The aim of this study was to investigate which aspects of health differ between working women with FM and nonworking women with FM. A cross-sectional study of 129 women of working age with FM which included clinical assessment, structured interviews, questionnaires and performance-based tests. The women were categorized as working or nonworking. Aspects of health are presented according to the International Classification of Functioning, Disability and Health (ICF). Working women with FM presented better health than nonworking women with FM in ratings of body function (FIQ pain p working women with FM than in nonworking women with FM (FIQ total, eight-item p = 0.001 and SF-36 PCS p working- and nonworking women in tests of physical capacity. FIQ pain was an independent explanatory factor for work in stepwise multiple logistic regression analysis (OR 0.95, CI 0.93- 0.98), p Working women with FM reported better health than nonworking women with FM in terms of pain, fatigue, stiffness, depression, disease specific health status and physical aspects of quality of life, which represent body functions and overall health status. However, they were equally impaired in tests of physical capacity. Moderate pain levels were compatible with work, while severe pain appeared to compromise work. Fatigue was better tolerated, as women scoring severe levels of fatigue worked.

Depression due to long work hours and sleep deprivation is a major occupational health concern. The extent to which work hours and sleep are associated with depression was investigated in employees of small- and medium-scale businesses in the Japanese city of Yashio, Saitama, and in the Ohta ward of Tokyo, a suburb of Tokyo, controlling for various potential confounders. In this cross-sectional study, a total of 2,643 full-time employees (1,928 men and 715 women), aged 18-79 years (mean = 45 years), in 296 small- and medium-scale businesses were surveyed from August 2002 to December 2002 using a self-administered questionnaire evaluating work hours, sleep status, and covariates including sociodemographic and socioeconomic factors, health behaviors, biological factors, medication usage, and occupational factors. Depression was assessed using the Center for Epidemiologic Studies Depression Scale. Prevalence of depression by work hours, sleep status, and covariates was analyzed by χ² test. Risk of depression by work hours, sleep status, and both combined was estimated by multivariate logistic regression analysis. Participants working > 10 hours per day, sleeping hours per day, and reporting insufficient sleep were, respectively, 37%, 43%, and 97% more likely to be depressed than those working 6 to 8 hours per day, sleeping 6 to hours per day, and reporting sufficient sleep (P working > 10 hours per day or > 8 to 10 hours per day with hours per day of sleep showed a 41%-169% higher prevalence of depression versus those working 6 to 8 hours per day with 6+ hours per day of sleep (P work-hour categories (6 to 8, > 8 to 10, and > 10 hours per day) showed a 62%-179% increase in the prevalence of depression versus those working 6 to 8 hours per day and reporting sufficient sleep (P work-hour category with 6+ hours of sleep or with subjective sufficient sleep. Depression associated with long work hours is primarily a result of sleep deprivation. Greater attention should be

With the need for improving existing nuclear data evaluations, (e.g., ENDF/B-VIII.0 and JEFF-3.3 releases) the first step was to evaluate the standards for use in such a library. This new standards evaluation made use of improved experimental data and some developments in the methodology of analysis and evaluation. In addition to the work on the traditional standards, this work produced the extension of some energy ranges and includes new reactions that are called reference cross sections. Since the effort extends beyond the traditional standards, it is called the neutron data standards evaluation. This international effort has produced new evaluations of the following cross section standards: the H(n,n), 6Li(n,t), 10B(n,α), 10B(n,α1 γ), natC(n,n), Au(n,γ), 235U(n,f) and 238U(n,f). Also in the evaluation process the 238U(n,γ) and 239Pu(n,f) cross sections that are not standards were evaluated. Evaluations were also obtained for data that are not traditional standards: the Maxwellian spectrum averaged cross section for the Au(n,γ) cross section at 30 keV; reference cross sections for prompt γ-ray production in fast neutron-induced reactions; reference cross sections for very high energy fission cross sections; the 252Cf spontaneous fission neutron spectrum and the 235U prompt fission neutron spectrum induced by thermal incident neutrons; and the thermal neutron constants. The data and covariance matrices of the uncertainties were obtained directly from the evaluation procedure.

To investigate the interrelationships between workplace violence, thriving at work and turnover intention among Chinese nurses and to explore the action mechanism among these variables. Workplace violence is a dangerous occupational hazard globally, and it is pervasive in the health service industry. As a corollary, workplace violence may produce many negative outcomes among nursing staff. Consequently, it hinders nurses' professional performance and reduces nursing quality. A cross-sectional online survey was conducted. A total of 1,024 nurses from 26 cities in China were recruited from February-May 2016. An anonymous questionnaire was used in this survey. Participants' completed data were collected using a demographics form and a 26-item questionnaire consisting of scales addressing workplace violence, thriving at work, job satisfaction, subjective well-being and turnover intention. To evaluate multivariate relationships, some multiple linear hierarchical regression analyses were performed. Workplace violence significantly negatively influenced nurses' job satisfaction and thriving at work, and significantly positively influenced nurses' turnover intention. Job satisfaction significantly predicted thriving at work and turnover intention. Job satisfaction not only fully mediated the relationship between workplace violence and thriving at work, but also partially mediated the relationship between workplace violence and turnover intention. Subjective well-being moderated the relationship between workplace violence and job satisfaction and the relationship between workplace violence and nurses' turnover intention. Adverse effects of workplace violence were demonstrated in this study. Decreases in job satisfaction were a vital mediating factor. The moderating effect of subjective well-being was helpful in reducing the harm of workplace violence to nurses and in decreasing their turnover intention. Workplace violence and its negative impact on nursing work should not

Shift work is associated with sleep disturbances, mental health problems, and job dissatisfaction. Disparities between male and female nurses in the effect of shift work on mental distress and job satisfaction have been scarcely studied. We aimed to examine differences between female and male nurses in the associations between shift work and job satisfaction and mental health. In this cross-sectional study, male and female nurses were recruited to rate their job satisfaction on the Generic Job Satisfaction Scale and to complete the General Health Questionnaire (GHQ-30). Associations between shift work, mental distress, and satisfaction were estimated from χ 2 tests and linear regression analyses using Stata/IC10. The study was approved by the ministry of health. Written informed consent was provided by all participants. In 2012, we recruited 372 registered nurses from the Hebron governorate in the occupied Palestinian territory. 28 (8%) nurses were excluded, and the final sample (n=344) included 213 (62%) women and 131 (38%) men. 338 nurses rated their job satisfaction, and 309 nurses completed the GHQ-30. After adjusting for covariates, men with shift work reported significantly lower job satisfaction (β-coefficient -3·3, 95% CI -6·2 to -0·5) than men with day schedules. Women with shift work reported significantly higher levels of mental distress (3·6, 95% CI 0·3 to 7·0) than women with day schedules. Distress was reported by more women than men, but this difference concerned only nurses working day shifts. No differences in job satisfaction associated with shift work was seen between men and women. We found no demonstrable interaction between sex and shift work for job satisfaction (β-coefficient -1·6, 95% CI -4·4 to 1·2) or distress (-0·03, 95% CI -5·3 to 5·3). Shift work was associated with low job satisfaction in male nurses and high distress in female nurses. Because the study had a cross-sectional design and both exposure and outcomes were

This study has been performed to determine the influence of rotating shift work on physical working capacity of Tunisian nurses and to design recommendations to managers so that they implement effective preventive measures. It is a cross-sectional design using a standardized questionnaire and many physical capacity tests on a representative sample of 1181 nurses and nursing assistants from two university hospital centers of the school of Medicine of Monastir located in the Tunisian Sahel. 293 participants have been recruited by stratified random sampling according to gender and departments. Maximum Grip strength, 30s sit-to-stand test, one leg test, Fingertip-to-Floor test, Saltsa test and peak expiratory flow were used to assess physical capacity. Work ability was assessed through the workability index. Mental and physical loads were heavily perceived in shift healthcare workers (p=0.01; p=0.02). The maximum grip force was stronger in rotating shift work nurses (p=0.0001). Regarding to the seniority subgroups in each kind of work schedule, the Body Mass Index was increasing with seniority in both schedules. All the physical tests, were better in less-than-ten-year groups. Peak Flow and grip strength were significantly better in less-than-ten-year seniority in shift work group. There is a need to improve the design of the existing shift systems and to reduce as much as possible shift schedule as well as to avoid shift schedule for over-10-year-seniority nurses.

For compact nuclear power plants, such as the nuclear space propulsion proposed by the TERRA project, aspects like mass, size and efficiency are essential drivers that must be managed during the project development. Moreover, for high temperature reactors, the use of liquid metal heat pipes as the heat removal mechanism provides some important advantages as simplicity and reliability. Considering these aforementioned aspects, this paper aims the development of the procedure necessary to calculate the microscopic absorption cross section data of several liquid metal to be used as working fluids with heat pipes; which will be later compared with the given data from JEF Report ⧣14. The information necessary to calculate the cross section data will be obtained from the latest ENDF library version. The NJOY system will be employed with the following modules: RECONR, BROADR, UNRESR and GROUPR, using the same specifications used to calculate the cross section data encountered in the JEF Report ⧣14. This methodology allows a comparison with published values, verifying the procedure developed to calculate the microscopic absorption cross section for selected isotopes using the TERRA reactor spectrum. Liquid metals isotopes of Sodium (Na), Lithium (Li), Thallium (TI) and Mercury (Hg) are part of this study. (author)

1980-01-01

Cross sections for neutron-induced reactions on 54 56 Fe were calculated by employing several nuclear models: optical, Hauser-Feshbach, preequilibrium and DWBA - in the energy range between 3 and 40 MeV. As a prelude to the calculations, the necessary input parameters were determined or verified through analysis of a large body of experimental data for both neutron- and proton-induced reactions in this mass and energy region. This technique also led to cross sections in which the simultaneous influence of available data types added to their consistency and reliability. Calculated cross sections as well as neutron and gamma-ray emission spectra were incorporated into an ENDF evaluation suitable for use to 40 MeV. 12 figures, 1 table
Evaluation of conservatisms and environmental effects in ASME Code, Section III, Class 1 fatigue analysis

1994-08-01

This report documents the results of a study regarding the conservatisms in ASME Code Section 3, Class 1 component fatigue evaluations and the effects of Light Water Reactor (LWR) water environments on fatigue margins. After review of numerous Class 1 stress reports, it is apparent that there is a substantial amount of conservatism present in many existing component fatigue evaluations. With little effort, existing evaluations could be modified to reduce the overall predicted fatigue usage. Areas of conservatism include design transients considerably more severe than those experienced during service, conservative grouping of transients, conservatisms that have been removed in later editions of Section 3, bounding heat transfer and stress analysis, and use of the ''elastic-plastic penalty factor'' (K 3 ). Environmental effects were evaluated for two typical components that experience severe transient thermal cycling during service, based on both design transients and actual plant data. For all reasonable values of actual operating parameters, environmental effects reduced predicted margins, but fatigue usage was still bounded by the ASME Section 3 fatigue design curves. It was concluded that the potential increase in predicted fatigue usage due to environmental effects should be more than offset by decreases in predicted fatigue usage if re-analysis were conducted to reduce the conservatisms that are present in existing component fatigue evaluations

Burnout is a psychosomatic syndrome widely observed in Chinese medical workers due to the increasing cost of medical treatment, excessive workload, and excessive prescribing behavior. No studies have evaluated the interrelationship among occupational burnout, work-family conflict, social support, and job satisfaction in medical workers. The aim of this study was to evaluate these relationships among medical workers in southwest China. This cross-sectional study was conducted between March 2013 and December 2013, and was based on the fifth National Health Service Survey (NHSS). A total of 1382 medical workers were enrolled in the study. Pearson correlation analysis and general linear model univariate analysis were used to evaluate the relationship of work-family conflict, self-reported social support, and job satisfaction with burnout syndrome in medical workers. We observed that five dimensions of job satisfaction and self-reported social support were negatively associated with burnout syndrome, whereas three dimensions of work-family conflict showed a positive correlation. In a four-stage general linear model analysis, we found that demographic factors accounted for 5.4% of individual variance in burnout syndrome (F = 4.720, Pfamily conflict, self-reported social support, and job satisfaction accounted for 2.6% (F = 5.93, Pfamily conflict and self-reported social support slightly affect the level of burnout syndrome, and that job satisfaction is a much stronger influence on burnout syndrome in medical workers of southwest China.

Developing Scientific Reasoning Through Drawing Cross-Sections

Science.gov (United States)

Hannula, K. A.

2012-12-01

Cross-sections and 3D models of subsurface geology are typically based on incomplete information (whether surface geologic mapping, well logs, or geophysical data). Creating and evaluating those models requires spatial and quantitative thinking skills (including penetrative thinking, understanding of horizontality, mental rotation and animation, and scaling). However, evaluating the reasonableness of a cross-section or 3D structural model also requires consideration of multiple possible geometries and geologic histories. Teaching students to create good models requires application of the scientific methods of the geosciences (such as evaluation of multiple hypotheses and combining evidence from multiple techniques). Teaching these critical thinking skills, especially combined with teaching spatial thinking skills, is challenging. My Structural Geology and Advanced Structural Geology courses have taken two different approaches to developing both the abilities to visualize and to test multiple models. In the final project in Structural Geology (a 3rd year course with a pre-requisite sophomore mapping course), students create a viable cross-section across part of the Wyoming thrust belt by hand, based on a published 1:62,500 geologic map. The cross-section must meet a number of geometric criteria (such as the template constraint), but is not required to balance. Each student tries many potential geometries while trying to find a viable solution. In most cases, the students don't visualize the implications of the geometries that they try, but have to draw them and then erase their work if it does not meet the criteria for validity. The Advanced Structural Geology course used Midland Valley's Move suite to test the cross-sections that they made in Structural Geology, mostly using the flexural slip unfolding algorithm and testing whether the resulting line lengths balanced. In both exercises, students seemed more confident in the quality of their cross-sections when the
Evaluation for ENDF/B-IV of the neutron cross sections for 235U from 82 eV to 25 keV

International Nuclear Information System (INIS)

Peelle, R.W.

1976-05-01

Capture and fission cross sections for 235 U in the ''unresolved resonance'' energy region were evaluated to permit determination of local-average resonance parameters for the ENDF/B-IV cross section file. Microscopic data were examined for infinitely dilute average fission and capture cross sections and also for intermediate structure unlikely to be reproduced by statistical fluctuations of resonance widths and spacings within known laws. Evaluated cross sections, averaged over lethargy intervals greater than 0.1, were obtained as an average over selected data sets after appropriate renormalization. Estimated uncertainties are given for these evaluated average cross sections. The ''intermediate'' structure fluctuations common to a few independent data sets were approximated by straight lines joining successive cross sections at 120 selected energy points; the cross sections at the vertices were adjusted to reproduce the evaluated average cross sections over the broad energy regions. Data sources and methods are reviewed, output values are tabulated, and some modified procedures are suggested for future evaluations. Evaluated fission and capture integrals for the resolved resonance region are also tabulated. These are not in agreement with integrals based on the resonance parameters of ENDF/B versions III and IV. 8 tables, 5 figures

The Working Party on International Nuclear Data Evaluation Co-operation (WPEC) has been established under the aegis of the OECD/NEA Nuclear Science Committee (NSC) to promote the exchange of information on nuclear data evaluations, validation and related topics. Its aim is also to provide a framework for co-operative activities between the members of the major nuclear data evaluation projects. This includes the possible exchange of scientists in order to encourage co-operation. Requirements for experimental data resulting from this activity are compiled. The WPEC determines common criteria for evaluated nuclear data files with a view to assessing and improving the quality and completeness of evaluated data. The parties to the project are: BROND (Russian Federation), ENDF (United States), JENDL (Japan) and JEFF (other NEA Data Bank member countries), as well as CENDL (China) in close co-operation with the Nuclear Data Section of the International Atomic Energy Agency (IAEA). This report has been issued by the WPEC Subgroup 34 with a view to solving a general discrepancy when calculating criticality benchmarks with plutonium, using the most recent evaluated data libraries. This international effort enabled the delivery of a single set of resonance parameters up to 2.5 keV. The large fluctuations of the prompt neutron multiplicities were correctly reproduced with a phenomenological decomposition of the multiplicity that involved the two-step (n,γf) process. Performances of the new 239 Pu evaluation were tested over a broad set of integral data (ICSBEP, mock-up experiments performed in the CEA facilities and in power reactors). An overall good agreement was achieved between the calculations and the experimental results. The international effort performed in the framework of this Subgroup enabled delivery of a single set of resonance parameters up to 2.5 keV able to provide good C/E results over a broad set of integral data. The resonance analysis has been performed

Neutron cross section evaluations of the fission-product isotopes, {sup 95}Mo, {sup 99}Tc, {sup 101}Ru, {sup 103}Rh, {sup 105}Pd, {sup 109}Ag, {sup 131}Xe, {sup 133}Cs, {sup 141}Pr, {sup 141}Nd, {sup 147}Sm, {sup 149}Sm, {sup 150}Sm, {sup 151}Sm, {sup 152}Sm, {sup 153}Eu, {sup 155}Gd, and {sup 157}Gd were carried out below the fast neutron energy region within the framework of the BNL-KAERI international collaboration. In the thermal energy region, the energy dependence of the various cross-sections was calculated by applying the multi-level Breit-Wigner formalism. In particular, the strong energy dependence of the coherent scattering lengths of {sup 155}Gd and {sup 157}Gd were determined and were compared with recent calculations of Lynn and Seeger. In the resonance region, the recommended resonance parameters, reported in the BNL compilation, were updated by considering resonance parameter information published in the literature since 1981. The s-wave and, if available, p-wave reduced neutron widths were analyzed in terms of the Porter-Thomas distribution to determine the average level spacings and the neutron strength functions. Average radiative widths were also calculated from measured values of resolved energy resonances. The average resonance parameters determined in this study were compared with those in the BNL and other compilations, as well as the ENDF/B-VI, JEF-2.2, and JENDL-3.2 data libraries. The unresolved capture cross sections of these isotopes, computed with the determined average resonance parameters, were compared with measurements, as well as the ENDF/B-VI evaluations. To achieve agreement with the measurements, in a few cases minor adjustments in the average resonance parameters were made. Because of astrophysical interest, the Maxwellian capture cross sections of these nuclides at a neutron temperature of 30 keV were computed and were compared with other compilations and evaluations.

The presence of substantial systematic discrepancies between the results of different experiments devoted to determining cross sections for partial photoneutron reactions—first of all, (γ, n), (γ, 2n), and (γ, 3n) reactions—is a strong motivation for studying the reliability and authenticity of these data and for developing methods for taking into account and removing the discrepancies in question. In order to solve the first problem, we introduce objective absolute criteria involving transitional photoneutron-multiplicity functions F 1 , F 2 , F 3 , …; by definition, their values cannot exceed 1.0, 0.5, 0.33, …, respectively. With the aim of solving the second problem, we propose a new experimental-theoretical approach. In this approach, reaction cross sections are evaluated by simultaneously employing experimental data on the cross section for the total photoneutron yield, σ expt (γ, xn) = σ expt (γ, n) + 2σ expt (γ, 2n) + 3σ expt (γ, 3n) + …, which are free from drawbacks plaguing experimental methods for sorting neutrons in multiplicity, and the results obtained by calculating the functions F theor 1 , F theor 2 , F theor 3 , … on the basis of the modern model of photonuclear reactions. The reliability and authenticity of data on the cross sections for (γ, n), (γ, 2n), and (γ, 3n) partial reactions—σ eval (γ, in) = F i theor σ expt (γ, xn)—were evaluated for the 90 Zr, 115 In, 112,114,116,117,118,119,120,122,124 Sn, 159 Tb, and 197 Au nuclei.
Which aspects of health differ between working and nonworking women with fibromyalgia? A cross-sectional study of work status and health

2012-01-01

Background Women with fibromyalgia (FM) describe great difficulties in managing work. Reported work ability in women with FM varies from 34 to 77 percent in studies from different countries. Many factors are suggested to affect the ability to work in women with FM, including pain, fatigue, impaired physical capacity and activity limitations. However, it is difficult to define to which extent symptom severity can be compatible with work. The aim of this study was to investigate which aspects of health differ between working women with FM and nonworking women with FM. Methods A cross-sectional study of 129 women of working age with FM which included clinical assessment, structured interviews, questionnaires and performance-based tests. The women were categorized as working or nonworking. Aspects of health are presented according to the International Classification of Functioning, Disability and Health (ICF). Results Working women with FM presented better health than nonworking women with FM in ratings of body function (FIQ pain p FIQ fatigue p = 0.006, FIQ stiffness p = 0.009, HADS-Depression p = 0.007). Ratings of overall health status were also significantly better in working women with FM than in nonworking women with FM (FIQ total, eight-item p = 0.001 and SF-36 PCS p FIQ pain was an independent explanatory factor for work in stepwise multiple logistic regression analysis (OR 0.95, CI 0.93- 0.98), p < 0.001. Conclusion Working women with FM reported better health than nonworking women with FM in terms of pain, fatigue, stiffness, depression, disease specific health status and physical aspects of quality of life, which represent body functions and overall health status. However, they were equally impaired in tests of physical capacity. Moderate pain levels were compatible with work, while severe pain appeared to compromise work. Fatigue was better tolerated, as women scoring severe levels of fatigue worked. PMID:23237146

Background Burnout is a psychosomatic syndrome widely observed in Chinese medical workers due to the increasing cost of medical treatment, excessive workload, and excessive prescribing behavior. No studies have evaluated the interrelationship among occupational burnout, work-family conflict, social support, and job satisfaction in medical workers. The aim of this study was to evaluate these relationships among medical workers in southwest China. Methods This cross-sectional study was conducted between March 2013 and December 2013, and was based on the fifth National Health Service Survey (NHSS). A total of 1382 medical workers were enrolled in the study. Pearson correlation analysis and general linear model univariate analysis were used to evaluate the relationship of work-family conflict, self-reported social support, and job satisfaction with burnout syndrome in medical workers. Results We observed that five dimensions of job satisfaction and self-reported social support were negatively associated with burnout syndrome, whereas three dimensions of work-family conflict showed a positive correlation. In a four-stage general linear model analysis, we found that demographic factors accounted for 5.4% of individual variance in burnout syndrome (F = 4.720, Pjob satisfaction accounted for 2.6% (F = 5.93, Pburnout syndrome, and medical workers without administrative duties had more serious burnout syndrome than those with administrative duties. Conclusions In conclusion, the present study suggests that work-family conflict and self-reported social support slightly affect the level of burnout syndrome, and that job satisfaction is a much stronger influence on burnout syndrome in medical workers of southwest China.

Job crafting, an employee-initiated job design/redesign, has become important for employees' well-being. However, most studies on the relationship between job crafting and employees' well-being have been conducted in western countries; thus, it is unclear whether job crafting can be effectively applied to Asian cultures, such as Japan, which emphasizes group harmony. The aim of this study was to examine the cross-sectional associations of self-reported job crafting with work engagement and psychological distress among employees in Japan. A questionnaire survey through the internet was conducted among all employees of a manufacturing company in Japan. We analyzed the data from 894 respondents, all employees with regular employment. Job crafting, work engagement, and psychological distress were assessed using the Japanese version of the Job Crafting Questionnaire, the Japanese version of the Utrecht Work Engagement Scale (UWES), and the Brief Job Stress Questionnaire (BJSQ), respectively. Hierarchical multiple regression showed that increasing structural job resources, social job resources, and challenging job demands was significantly and positively associated with work engagement ( β = 0.31, p engagement and lower psychological distress. In addition, increasing social job resources and challenging job demands are also associated with higher work engagement.

Full Text Available Background and aims : The ability of work is the basis of well-being for all of us. Many factors affect the work ability such as work and work condition, work organization and human resource. The aim of this study was to assess the work ability among car manufacturing workers and determine the relationship between the work ability index with individual characteristics and life style factors. Methods : The study was a descriptive cross-sectional investigation. The subjects comprised of 271 workers with mean age of 35 years who occupied by a car manufacturing Company. They completed the Work Ability Index Questionnaire during semi interview sessions. The job groups of Painting Shop, assembling line, office department, and technical section were studied. Statistical tests including one-way ANOVA, t-test, Kruskal wallis were used for analyzing the relationship between work ability index and individual characteristic as well as life style factors. To test the distribution of work ability index score categories, a chi-square test was used and finally, Spearman correlation coefficient was used in order to determine correlation between the final of work ability index score with any of questionnaire items. Results : The mean value of work ability index in this study was (37.67 with SD=5.87. The WAI categories were 17.71% in "excellent", 38.75% in "good", 36.16% in "moderate", and 7.4% in "poor" levels. Association between life style factors (obesity, smoking, exercise and WAI was statistically significant (P< .0.001 . Lower WAI was associated with increasing the age, high work experience and lower education (P<.0.001. Meanwhile, physical demand of the jobs was strongly associated with the WAI score (P<.0.001. Conclusion : On the basis of Finnish Institute of Occupational Health, the value of work ability in current study was in good category(37-43; but, concerning the mean age (35 years of the studied population the mean value of work

To investigate frequency, type, and characteristics of work anxieties in patients with somatic illness. Cross-sectional observation study. Neurology, orthopedic, and cardiology rehabilitation clinics. Patients (N=1610; age, 18-65y) with work anxieties. Not applicable. Patients who scored high on at least 2 of 9 items in the work-anxiety screening questionnaire and who reported impairment were investigated with a differential diagnostic interview on work anxieties and with the Mini-International Neuropsychiatric Interview on non-work-related common mental disorders. Patients also filled out a self-rating questionnaire on their subjective symptom load and sociodemographic data. Approximately 20% to 27% of the investigated inpatients in somatic rehabilitation (altogether n=393) received a work-anxiety diagnosis. Patients with orthopedic illness report highest work anxiety and have previous longest sick leave (20.6wk in the past 12mo). Patients with orthopedic illness suffer from work-related adjustment disorder with anxiety, social anxieties, and workplace phobias, whereas patients with cardiac illness are more often affected by hypochondriac anxieties. Anxieties of insufficiency and worrying occur equally in all indications. About a quarter of patients in somatic rehabilitation are in need of additional diagnostic attention owing to work anxieties. Differential diagnostic of work anxiety is needed for initiating adequate therapeutic action. Somatic rehabilitation physicians should be aware of work anxieties in their patients, especially in patients with orthopedic illness with previous long-term sick leave.

2005-01-01

Nuclear data were evaluated on Zr isotopes, 93 Nb and W isotopes for neutron- and proton-induced reactions up to 200 MeV. Optical model potential parameters were determined to give good agreements with experimental values of elastic-scattering, total, and total-reaction cross sections by the traditional phenomenological approach. The GNASH nuclear model code was used for evaluations of particle-production cross sections. Since the direct inelastic-scatterings induced by the excitations of giant resonances are not negligible for medium/heavy nuclei, the calculation was performed to take them into consideration. For composite-particle emission cross sections from pre-equilibrium states, semi-empirical models were utilized to give good agreements with experimental data. Evaluated cross sections were compared with experimental values and the LA150 evaluations. (author)

ZZ ENDL82, Evaluated Charged Particle, Neutron, Photon Cross-Section Library

International Nuclear Information System (INIS)

2001-01-01

Description of program or function: - Format: Described in the manual; - Number of groups: (energies between 100 eV and 100 MeV); - Nuclides: 94 (Z 1 to 99); - Origin: LLNL Evaluated Nuclear Data Library. ENDL82 is a collection of evaluated data for neutron-induced reactions, photon interactions with matter, and charged-particle-induced reactions. It is maintained in a computer-oriented system. All interpolable quantities for neutron-induced reactions are presented so that linear interpolation between successive entries yields values that are consistent with stated experimental errors, where experiments exist, or that adhere to an assumed law, such as 1/v energy dependence, within a small fraction (typically 1%). In the case of an assumed energy-dependence law for cross sections, this is accomplished by creating a large number of (energy, cross section) pairs by computer and subsequently thinning the points to a specified accuracy, using the subroutine THINER. All angular distributions are differential probabilities normalized to an integral of unity over the cosine of the scattering angle. All energy distributions of secondary particles are presented as normalized Legendre polynomial representations. The linear interpolation will construct an acceptable angular distribution at an intermediate energy

1 - Description of problem or function: Format: SAND-II; Number of groups: 640 fine group cross section values; Nuclides: Li, B, F, Na, Mg, Al, S, Sc, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Br, Nb, Mo, Rh, Pd, Ag, In, Sb, I, Cs, La, Eu, Sm, Dy, Lu, Ta, W, Re, Au, Th, U, Np, Pu. Origin: ENDF/B-V mainly, ENDF/B-IV, INDL/V. This library forms in combination with the DAMSIG81 library a convenient source of evaluated energy dependent cross section sets which may be used in the determination of neutron spectra by means of adjustment (or unfolding) procedures or which can be used for the determination of integral parameters (such as damage-to-activation ratio) useful in characterising the neutron spectra. The energy dependent fine group cross section data are presented in a 640 group structure of the SAND-II type. This group structure has 45 energy groups per energy decade below 1 MeV and a group width of 100 KeV above 1 MeV. The total energy span of this group structure is from 10 -10 MeV to 20 MeV. The library has the SAND-II format, which implies that a special part of the library has to contain cover cross section data sets. These cross section data sets are required in the SAND-II program for taking into account the influence of special detector surroundings which may be used during an irradiation. 2 - Method of solution: The selection of the reactions from the evaluated nuclear data libraries was determined by various properties of the reactions for neutron metrology. For this reason all the well- known reactions of the ENDF/B-V dosimetry file are included but these data are supplemented with cross section sets for less well known metrology reactions which may become of interest

Objective: To investigate the clinical characteristics of cesarean section (C-section) complicating with DIC and evaluate the interventional embolization as a treatment of post-C-section hemorrhage. Methods: In total 12 cases of post-C-section massive hemorrhage and DIC were retrospectively studied. Results: Hemostasia was successfully obtained after intervention in all patients. Bleeding was immediately ceased after the procedure in 10 cases out of 12, and bleeding was significantly decreased after intervention, which stop gradually within 3 and 7 days in other 2 cases. Excellent prognosis was arcbieved in all cases. Conclusion: Post-C-section bleeding with DIC is characterized by massive blood loss and progressive deterioration of the patients condition. Interventional embolization provides a quick, thorough, lasting, safe and reliable control of the bleeding, with which uterectomy is able to be avoid. (authors)

The series of this study describes the necessity of the evaluation of team work from two aspects of operator's behavior and operators' mind. The authors propose Team Work Element Model which consists of necessary elements to build high performance team. This report discusses a method to evaluate team work from the second aspect, that is, competency trust, competition, for-the team spirit, etc. The authors survey the previous studies on psychological measures and organize a set of questions to evaluate 10 team work sub elements that are the parts of Team Work Element Model. The factor analysis shows that this set of questions is consists of 13 factors such as task-oriented leadership, harmony-oriented team atmosphere, etc. Close examination of the questions in each factor shows that 8 of 10 team work sub elements can be evaluated by this questionnaire. In addition, this questionnaire comprises scales additional 8 scales such as job satisfaction, leadership, etc. As a result, it is possible to evaluate team work from more comprehensive view points.

Evaluation of Cross-Section Sensitivities in Computing Burnup Credit Fission Product Concentrations

International Nuclear Information System (INIS)

Gauld, I.C.

2005-01-01

U.S. Nuclear Regulatory Commission Interim Staff Guidance 8 (ISG-8) for burnup credit covers actinides only, a position based primarily on the lack of definitive critical experiments and adequate radiochemical assay data that can be used to quantify the uncertainty associated with fission product credit. The accuracy of fission product neutron cross sections is paramount to the accuracy of criticality analyses that credit fission products in two respects: (1) the microscopic cross sections determine the reactivity worth of the fission products in spent fuel and (2) the cross sections determine the reaction rates during irradiation and thus influence the accuracy of predicted final concentrations of the fission products in the spent fuel. This report evaluates and quantifies the importance of the fission product cross sections in predicting concentrations of fission products proposed for use in burnup credit. The study includes an assessment of the major fission products in burnup credit and their production precursors. Finally, the cross-section importances, or sensitivities, are combined with the importance of each major fission product to the system eigenvalue (k eff ) to determine the net importance of cross sections to k eff . The importances established the following fission products, listed in descending order of priority, that are most likely to benefit burnup credit when their cross-section uncertainties are reduced: 151 Sm, 103 Rh, 155 Eu, 150 Sm, 152 Sm, 153 Eu, 154 Eu, and 143 Nd

The main and additional criteria used in evaluation (in percent) of loss of professional working capacity are characterized. Criteria common for forensic medical and medical social expert evaluations and differences between them are discussed. These differences are due to the fact that forensic medical expert evaluations are based on the Civil and Civil Processual Codes of the Russian Federation but not on the departamental norm-setting documents.

A program is being carried out at Lawrence Livermore National Laboratory to develop high-energy evaluated nuclear data libraries for use in Monte Carlo simulations of cancer radiation therapy. In this report we describe evaluated cross sections and kerma factors for neutrons with incident energies up to 100 MeV on 12 C. The aim of this effort is to incorporate advanced nuclear physics modeling methods, with new experimental measurements, to generate cross section libraries needed for an accurate simulation of dose deposition in fast neutron therapy. The evaluated libraries are based mainly on nuclear model calculations, benchmarked to experimental measurements where they exist. We use the GNASH code system, which includes Hauser-Feshbach, preequilibrium, and direct reaction mechanisms. The libraries tabulate elastic and nonelastic cross sections, angle-energy correlated production spectra for light ejectiles with A≤and kinetic energies given to light ejectiles and heavy recoil fragments. The major steps involved in this effort are: (1) development and validation of nuclear models for incident energies up to 100 MeV; (2) collation of experimental measurements, including new results from Louvain-la-Nueve and Los Alamos; (3) extension of the Livermore ENDL formats for representing high-energy data; (4) calculation and evaluation of nuclear data; and (5) validation of the libraries. We describe the evaluations in detail, with particular emphasis on our new high-energy modeling developments. Our evaluations agree well with experimental measurements of integrated and differential cross sections. We compare our results with the recent ENDF/B-VI evaluation which extends up to 32 MeV

Poor hospital work environments affect physicians' work stress. With a focus on hospital pediatricians, we sought to investigate associations between work stress, burnout, and quality of care. A cross-sectional study was conducted in N = 96 pediatricians of a German academic children's hospital (response rate = 73.8 %). All variables were assessed with standardized questionnaires. Multivariate regression analyses were applied to investigate associations after adjusting for potential confounders. Critically high work stress (effort/reward ratio, ERR > 1.0) was reported by N = 25 (28.4 %) participants. Pediatricians in inpatient wards had significantly more work stress than their colleagues in intensive care units and outpatient wards; 10.2 % of surveyed pediatricians reported critically high burnout. Again, inpatient ward staff reported significantly increased emotional exhaustion. After controlling for several confounders, we found that pediatricians with high work stress and emotional exhaustion reported reduced quality of care. Mediation analyses revealed that especially pediatricians' emotional exhaustion partially mediated the effect of work stress on quality of care. Results demonstrate close relationships between increased work stress and burnout as well as diminished quality of care. High work stress environments in pediatric care influence mental health of pediatricians as well as quality of patient care. • The quality of pediatricians' work environment in the hospital is associated with their work stress and burnout. • The consequences of pediatricians' work life for the quality of care need to be addressed in order to inform interventions to improve work life and care quality. • Our study shows associations between increased work stress and burnout with mitigated quality of care. • Beyond indirect effects of work stress through emotional exhaustion on quality of care we also observed direct detrimental effects of pediatricians

This is the final report concerning the evaluated neutron cross sections of 28 fission product nuclides adopted in the first version of Japanese Evaluated Nuclear Data Library (JENDL-1). These 28 nuclides were selected as being most important for fast reactor calculations, and are 90 Sr, 93 Zr, 95 Mo, 97 Mo, 99 Tc, 101 Ru, 102 Ru, 103 Rh, 104 Ru, 105 Pd, 106 Ru, 107 Pd, 109 Ag, 129 I, 131 Xe, 133 Cs, 135 Cs, 137 Cs, 143 Nd, 144 Ce, 144 Nd, 145 Nd, 147 Pm, 147 Sm, 149 Sm, 151 Sm, 153 Eu and 155 Eu. The status of the experimental data was reviewed over the whole energy range. The present evaluation was performed on the basis of the measured data with the aid of theoretical calculations. The optical and statical models were used for evaluation of the smooth cross sections. An improved method was developed in treating the multilevel Breit-Wigner formula for the resonance region. Various physical parameters and the level schemes, adopted in the present work are discussed by comparing with those used in the other evaluations such as ENDF/B-IV, CEA, CNEN-2 and RCN-2. Furthermore, the evaluation method and results are described in detail for each nuclide. The evaluated total, capture and inelastic scattering cross sections are compared with the other evaluated data and some recent measured data. Some problems of the present work are pointed out and ways of their improvement are suggested. (author)

Hospital ethics committees (HECs) and ethicists generally describe themselves as engaged in four domains of practice: case consultation, research, education, and policy work. Despite the increasing attention to quality indicators, practice standards, and evaluation methods for the other domains, comparatively little is known or published about the policy work of HECs or ethicists. This article attempts to open the "black box" of this health care ethics practice by providing two detailed case examples of ethics policy reviews. We also describe the development and application of an evaluation strategy to assess the quality of ethics policy review work, and to enable continuous improvement of ethics policy review processes. Given the potential for policy work to impact entire patient populations and organizational systems, it is imperative that HECs and ethicists develop clearer roles, responsibilities, procedural standards, and evaluation methods to ensure the delivery of consistent, relevant, and high-quality ethics policy reviews.

Despite improvements in treatment, acute coronary syndrome remains a substantial cause for prolonged sick absences and premature retirement. Knowledge regarding what benefits return to work is limited, especially the effect of psychological processes and psychosocial work factors. The purposes of this cross-sectional study were two-fold: to examine associations between adverse psychosocial job conditions and fear-avoidance beliefs towards work, and to determine whether such beliefs mediated the relationship between work conditions and expected return to work in acute coronary syndrome survivors. Study inclusion criteria: acute myocardial infarction or unstable angina diagnosis, below 65 years of age, being a resident in the West county of Sweden and currently working. In all, 509 individuals (21.8 % women) accepted study participation and for whom all data of study interest were available for analysis. Psychosocial work variables; job demand-control and effort-reward imbalance, were assessed with standard questionnaire batteries. Linear regression models were used to investigate relationships between psychosocial factors and fear-avoidance, and to evaluate mediator effects for fear-avoidance. Both total sample and gender stratified analyses were calculated. Fear-avoidance beliefs about work were associated to psychosocial job environments characterized by high strain (β 1.4; CI 1.2-1.6), active and passive work and high effort-reward imbalance (β 0.6; CI 0.5-0.7). Further, such beliefs also mediated the relationship between adverse work conditions and expected time for return to work. However, these results were only observed in total sample analyses or among or male participants. For women only high strain was linked to fear-avoidance, and these relationships became non-significant when entering chosen confounders. This cross-sectional study showed that acute coronary syndrome survivors, who laboured under adverse psychosocial work conditions, held fear

Full Text Available Sarcoidosis is a multisystemic granulomatous disease of unknown etiology which affects most frequently the hilar lymph nodes and lungs. Symptomatic involvement of the central nervous system may develop in patients diagnosed with sarcoidosis or it may be the initial manifestation of the disease. This is a case report of 48-year old female patient admitted to our clinic for evaluation of working ability. The patient had a total of 24 years of service and occupational exposure and she has been employed as supplies procurement officer. On admission, she complained of the following discomforts: eye-lid pain, intellectual fatigue, psychic uneasiness, forgetfulness, dyspnea and productive cough. Neurological findings indicated the presence of the right eye ophthalmoplegia, psychoorganic syndrome and neurosarcoidosis. Ophthalmological examination evidenced bilateral ptosis and presence of anisocoria. Magnetic resonance imaging revealed discrete focal lesions of the pons (paracentral left and parietal corona radiata of the left hemisphere. Based on performed examinations and diagnostics procedures, final evaluation of patient’s working ability concluded that the patient was not capable of psychic strains and jobs associated with material accountability.

A Working Party on International Evaluation Co-operation was established under the sponsorship of the OECD/NEA Nuclear Science Committee (NSC) to promote the exchange of information on nuclear data evaluations, validation and related topics. Its aim is also to provide a framework for co-operative activities between members of the major nuclear data evaluation projects. This includes the possible exchange of scientists in order to encourage co-operation. Requirements for experimental data resulting from this activity are compiled. The working party determines common criteria for evaluated nuclear data files with a view to assessing and improving the quality and completeness of evaluated data. The parties to the project are: ENDF (United States), JEFF/EFF (NEA Data Bank member countries) and JENDL (Japan). Co-operation with evaluation projects of non-OECD countries is organised through the Nuclear Data Section of the International Atomic Energy Agency (IAEA). This report was issued by Subgroup 7, which was in charge of producing new evaluated neutron cross-section standards. When starting the project, there was a general consensus on the need to update these standards, as significant improvements had been made to the experimental database since 1991 when the last evaluation of these standards was performed. The present work was accomplished through efficient collaboration between a task force of the US Cross-section Evaluation Working Group (CSEWG), a Co-ordinated Research Project (CRP) of the International Atomic Energy Agency (IAEA) and Subgroup 7 of the Working Party on International Evaluation Co-operation (WPEC) of the NEA Nuclear Science Committee. Work is reported on the results of an international effort to evaluate the neutron cross-section standards. The evaluations include the H(n,n), 6 Li(n,t), 10 B(n,α), 10 B(n,α1γ), 197 Au(n,γ), 235 U(n,f) and 238 U(n,f) standard reactions. Evaluations were also produced for the non-standard 238 U(n,γ) and 239 Pu

Neutron cross sections for a complete set of Nd isotopes, {sup 142,143,144,145,146,147,148,150}Nd, were evaluated in the incident energy range from 10{sup -5} eV to 20 MeV. In the low energy region, including thermal and resolved resonances, our evaluations are based on the latest data published in the Atlas of Neutron Resonances. In the unresolved resonance region we performed additional evaluation by using the averages of the resolved resonances and adjusting them to the experimental data. In the fast neutron region, we used the nuclear reaction model code EMPIRE-2.19 validated against the experimental data. The results are compared to the existing nuclear data libraries, including ENDF/B-VI.8, JENDL-3.3 and JEFF-3.1, and to the available experimental data. The new evaluations are suitable for neutron transport calculations and they were adopted by the new evaluated nuclear data file of the United States, ENDF/B-VII.0, released in December 2006.

Highlights: → In the present work, we have analyzed the CREOLE experiment on the reactivity temperature coefficient (RTC) by using the three-dimensional continuous energy code (MCNP5) and the last updated nuclear data evaluations. → Calculation-experiment discrepancies of the RTC were analyzed and the results have shown that the JENDL3.3 and JEFF3.1 evaluations give the most consistent values. → In order to specify the source of the relatively large discrepancy in the case of ENDF-BVII nuclear data evaluation, the k eff discrepancy between ENDF-BVII and JENDL3.3 was decomposed by using sensitivity and uncertainty analysis technique. - Abstract: In the present work, we analyze the CREOLE experiment on the reactivity temperature coefficient (RTC) by using the three-dimensional continuous energy code (MCNP5) and the last updated nuclear data evaluations. This experiment performed in the EOLE critical facility located at CEA/Cadarache, was mainly dedicated to the RTC studies for both UO 2 and UO 2 -PuO 2 PWR type lattices covering the whole temperature range from 20 deg. C to 300 deg. C. We have developed an accurate 3D model of the EOLE reactor by using the MCNP5 Monte Carlo code which guarantees a high level of fidelity in the description of different configurations at various temperatures taking into account their consequence on neutron cross section data and all thermal expansion effects. In this case, the remaining error between calculation and experiment will be awarded mainly to uncertainties on nuclear data. Our own cross section library was constructed by using NJOY99.259 code with point-wise nuclear data based on ENDF-BVII, JEFF3.1 and JENDL3.3 evaluation files. The MCNP model was validated through the axial and radial fission rate measurements at room and hot temperatures. Calculation-experiment discrepancies of the RTC were analyzed and the results have shown that the JENDL3.3 and JEFF3.1 evaluations give the most consistent values; the discrepancy is

In this report we investigate the adequacy of the available {sup 233}U cross-section data for calculation of experimental critical systems. The {sup 233}U evaluations provided in two evaluated nuclear data libraries, the U.S. Data Bank [ENDF/B (Evaluated Nuclear Data Files)] and the Japanese Data Bank [JENDL (Japanese Evaluated Nuclear Data Library)] are examined. Calculations were performed for six thermal and ten fast experimental critical systems using the S{sub n} transport XSDRNPM code. To verify the performance of the {sup 233}U cross-section data for nuclear criticality safety application in which the neutron energy spectrum is predominantly in the epithermal energy range, calculations of four numerical benchmark systems with energy spectra in the intermediate energy range were done. These calculations serve only as an indication of the difference in calculated results that may be expected when the two {sup 233}U cross-section evaluations are used for problems with neutron spectra in the intermediate energy range. Additionally, comparisons of experimental and calculated central fission rate ratios were also made. The study has suggested that an ad hoc {sup 233}U evaluation based on the JENDL library provides better overall results for both fast and thermal experimental critical systems.

The aim is to use the research portfolio evaluation protocol developed by HSL to evaluate the Probabilistic Safety Assessment (PSA) portfolio, both to draw conclusions about the PSA portfolio and as a pilot study to show the suitability of the evaluation protocol. The objectives of the work are: (1) To collect sufficient information to carry out a preliminary review of the portfolio; (2) o produce a plan of work detailing the time and costs to carry out a full evaluation of the PSA portfolio; (3) to evaluate the PSA portfolio of research; (4) to produce a report of the evaluation of the PSA portfolio; (5) if necessary, to make changes to the methodology in light of the experience gained in the evaluation of the PSA research portfolio. This report completes objectives 1 and 2. It details the plan of work for the evaluation of the PSA research portfolio. The plan has shown that the evaluation of the PSA research portfolio has many difficulties to overcome. It is suitable as a pilot study to show the suitability of the portfolio evaluation protocol and will provide valuable information that can be used to improve it. The evaluation of the PSA portfolio will require a considerable amount of time and effort to complete. The task analysis has shown it to be of the order of Pound Sterling 25k and to take two months to complete after this preliminary data collection. The plan to evaluate the PSA research portfolio detailed in this report should be carried out and the lessons learned by carrying out this pilot study should be used to improve the evaluation protocol

This study aimed to analyse and compare differences in occupational stress, depressive symptoms, work ability and working environment among residents working in various medical specialties. 435 German hospital residents in medical training working in 6 different medical specialties participated in a cross-sectional survey study. Physicians were asked about their working conditions and aspects of mental health and work ability. The Copenhagen Psychosocial Questionnaire, the Work Ability Index, the ICD-10 Symptom Rating and the Perceived Stress Questionnaire were used to measure working conditions, mental health and work ability. Results show that up to 17% of the physicians reported high levels of occupational distress and 9% reported high levels of depressive symptoms. 11% of the hospital physicians scored low in work ability. Significant differences between medical specialties were demonstrated for occupational distress, depressive symptoms, work ability, job demands and job resources. Surgeons showed consistently the highest levels of perceived distress but also the highest levels of work ability and lowest scores for depression. Depressive symptoms were rated with the highest levels by anaesthesiologists. Significant associations between physicians' working conditions, occupational distress and mental health-related aspects are illustrated. Study results demonstrated significant differences in specific job stressors, demands and resources. Relevant relations between work factors and physicians' health and work ability are discussed. These findings should be reinvestigated in further studies, especially with a longitudinal study design. This work suggests that to ensure physicians' health, hospital management should plan and implement suitable mental health promotion strategies. In addition, operational efficiency through resource planning optimisation and work process improvements should be focused by hospital management. Published by the BMJ Publishing Group
European Approaches to Work-Related Stress: A Critical Review on Risk Evaluation

Full Text Available In recent years, various international organizations have raised awareness regarding psychosocial risks and work-related stress. European stakeholders have also taken action on these issues by producing important documents, such as position papers and government regulations, which are reviewed in this article. In particular, 4 European models that have been developed for the assessment and management of work-related stress are considered here. Although important advances have been made in the understanding of work-related stress, there are still gaps in the translation of this knowledge into effective practice at the enterprise level. There are additional problems regarding the methodology in the evaluation of work-related stress. The European models described in this article are based on holistic, global and participatory approaches, where the active role of and involvement of workers are always emphasized. The limitations of these models are in the lack of clarity on preventive intervention and, for two of them, the lack of instrument standardization for risk evaluation. The comparison among the European models to approach work-related stress, although with limitations and socio-cultural differences, offers the possibility for the development of a social dialogue that is important in defining the correct and practical methodology for work stress evaluation and prevention.

Evaluation of fission spectra and cross sections by zero-leakage core experiments

1979-01-01

A series of unit k-infinity core experiments were performed in FCA of JAERI to obtain the information on the equivalence of 239 Pu to 235 U in fast reactors, and to examine the inelastic slowing down cross section of 238 U. Three assemblies were built. Each assembly consists of a test zone (about 44l) of nearly unit k-infinity, a 20% enriched uranium driver and a natural uranium blanket. Assembly IV-1 (first built in 1969 and rebuilt in 1972) is an all uranium system, and Assemblies IV-1-P, IV-1-P' have a plutonium/natural uranium test zone. Three assemblies are nearly the same from the view-point of the slowing down cross section in the main energy region of the neutron spectrum, since 238 U occupies the most part of the composition. The main difference between Assembly IV-1 and the latter two is the difference in the fissile material. Fission rate ratios and k-infinity values were measured to obtain knowledge of the fission spectra and cross sections important for the criticality. In order to evaluate the inelastic slowing down cross section of 238 U, neutron spectra were measured with various methods. The analysis was done with four cross section sets. The agreement of k-infinity values between the experiment and the calculation is unsatisfactory, especially for Pu/NU systems

Protection of working mothers: operational guide document. The aim of this operational guide document is to protect the health of working mothers and their babies during pregnancy, puerperium and breastfeeding. The project was developed by a technical working group which included professionals in the pertinent fields from the Workplace Prevention and Safety Services of the local Vasta-2 Area of the Marche Regional Health Service:physicians, health assistants, and nurses. It is considered to be a useful tool for risk assessment at the workplace aimed at professionals who are involved, with various duties and responsibilities, in the health care of the working mother. This paper consists of two functionally related sections, "Table of risks" and "Technical specifications". In the "Table of Risks" section, the occupational hazards for women during pregnancy or postpartum were analyzed with the highest possible degree of care. To this end the technical group provided, for each occupational hazard, its own operational suggestions, in relation to legislation, current scientific knowledge and Guidelines of other Italian Regions. The Marche Regional Section of the Italian Society of Occupational Health and Industrial Hygiene (SIMLII) participated in the final draft of the entire document. The second section, "Technical Specifications", illustrates the main tasks and any risks involved in the 34 manufacturing sectors most prevalent in this area. This operational guide document is intended to be the beginning of a common strategy in public health to achieve a wider field of action in promotion and information aimed at protecting the reproductive health of working mothers.

Calculated fusion-evaporation cross sections from five different codes are compared to experimental data. The present comparison extents over a large range of nuclei and isotopic chains to investigate the evolution of experimental and calculated cross sections. All models more or less overestimate the experimental cross sections. We found reasonable agreement by using the geometrical average of the five model calculations and dividing the average by a factor of 11.2. More refined analyses are made for example for the 100Sn region.

Presenteeism In Work Life: An Evaluation In Hotel Industry

Directory of Open Access Journals (Sweden)

Ebru Arslaner

2015-12-01

Full Text Available This study aims to examine presenteeism problem encountered in businesses frequently and evaluate this issue for hotel enterprises. Presenteeism is defined as when an employee shows up for work even though he or she is sick and performs ineffectively. Thus, it causes great costs for companies due to ineffective work performance. This situation arises in hotel businesses due to labor-intensive features of industry. It is considered that the intensity of human relationships and long shifts in hotel businesses induce stressfull working conditions and that factors increase presenteeism. Businesses could produce solutions for presenteeism with practices that prioritise employees satisfaction and take precautions to remedy physical and mental health of employees.

Monitoring occupational related stress can be an important tool for policy makers. The Italian nursing research gave little attention to nurses' occupational stress. The aims of this study is to estimate the prevalence of occupational stress and evaluate risks factors among Italian nurses in order to evaluate health promotion intervention. Cross-sectional study on a convenience sample of nurses from three Italian public hospitals was carried out. The Nursing Stress Scale was administrated together with socio-demographic data information(age, occupational age, family structure etc). The Nursing Stress Scale includes 34 items with a score from 0 to 3. Seven areas of job related stress are investigate in the scale: conflict with physicians, inadequate training, lack of support, conflict with other nurses, workload, uncertainty about treatments, death and suffering. Scores were calculated for each item and for each area. Associations between stress scores and socio-demographic data were analyzed. 231 nurses participated to the study. The two stress areas with the highest scores were "workload" (1.58) and "death and suffering" (1.39). Among the 13 items that exceed the overall mean stress score (i.e. 1.07), five belong to the "workload" area. "Watching a suffering patient" is the single item with the highest mean score. Demographic data associated to higher stress scores are, female gender (p=0.03) and working with night shifts (p=0.02). Intention to leave the nursing profession is associated to higher stress scores (p=0.002). Age, occupational age, time to commute to work, number of children, having disabled relatives at home, were not correlated to higher stress scores. Our study provides data regarding nurses' occupational stress that was not available before. This data may be useful for policy makers to plan preventive

In the 10 -5 eV - 200 keV energy range a coherent resolved resonance parameter set has been determined for each titanium isotope. From these sets the titanium capture cross section has been calculated with the Reich-Moore formalism and corrected for the missing resonances. From 200 keV up to 20 MeV all the isotopic cross sections were calculated with the help of two statistical model codes NCNR and FISPRO. These calculations have been adjusted on available 50 Ti(n,γ) 51 Ti and Ti(n,γ) experimental results. The elemental titanium capture cross section has been obtained as the weighted sum of the isotopic cross sections. The present evaluation is descriptive of the experimental values. The comparison of the present evaluation with ENDF/BIV shows the ameliorations brought in this cross section: a better description of all the resonances known in the 1 keV - 200 keV energy range; above 200 keV the new data give a more realistic shape showing compound nucleus competition of prominent inelastic scattering channels. As titanium is used as structural material for fast reactors the capture cross section integrals for the two evaluations in different energy ranges are compared. These comparisons show considerable discrepancies in some areas. Thus the new evaluation may change the results of reactor calculations

This study aimed to describe intrapersonal characteristics (professional values, personality, empathy, and job involvement), work performance as perceived by nurses, and caring behaviors as perceived by patients, and to examine the relationships among these variables. A cross-sectional design was employed. A sample was recruited of 218 nurses and 116 patients in four private hospitals and four public hospitals. Data were collected using self-report measures. Data analysis included descriptive statistics, exploratory and confirmatory factor analyses, hierarchical linear modelling, correlations, and structural equation modeling. Nurses perceived their work performance to be of high quality. Among the intrapersonal characteristics, nurses had high scores for professional values, and moderately high scores for personality, empathy and job involvement. Patients perceived nurses' caring behaviors as moderately high. Professional values of nurses were the only selected intrapersonal characteristic with a statistically significant positive relationship, of practical importance, with work performance as perceived by nurses and with caring behaviors as perceived by patients at ward level. Managers can enhance nurses' work performance and caring behaviors through provision of in-service training that focuses on development of professional values. © 2018 John Wiley & Sons Australia, Ltd.
Development of the next generation code system as an engineering modeling language (6). Development of a cross section adjustment and nuclear design accuracy evaluation solver

2008-01-01

A new cross section adjustment and nuclear design accuracy evaluation solver was developed as a set of modules for MARBLE (multi-purpose advanced reactor physics analysis system based on language of engineering). In order to enhance the system extendibility and flexibility, the object-oriented design and analysis technique was adopted to the development. In the new system, it is easy to add a new design accuracy evaluation method because a new numerical calculation module is independent from other modules. Further, several new functions such as searching and editing calculation data are provided in the new solver. These functions can be easily customised by users because they are designed to work cooperatively with Python scripting language, which is used as a user interface of the MARBLE system. In order to validate the new solver, a test calculation was performed for a realistic calculation case of creating a new unified cross section library. In the test calculation, results calculated by the new solver agreed well with those by the conventional code system. In addition, it is possible to reuse existing input data files prepared for the conventional code system because the new solver utilities support the conventional formats. Because the new solver implements all main functions of the conventional code system, MARBLE can be used as a new calculation code system for cross section adjustment and nuclear design accuracy evaluation

Full Text Available Introduction and purpose: Work fatigue is one of the main causes of workrelated musculoskeletal disorders and reduced productivity in industry. Therefore, it is vital to evaluate work fatigue, especially muscle fatigue, to determine the permissible workload. This study aimed to evaluate muscle fatigue of brick field workers. Methods: This cross-sectional study was conducted on transportation sector workers in Pey Dezh Brick Production Company, Golestan, Iran in 2015. In this research, the qualitative of Muscle Fatigue Assessment (MFA method was used to assess the level of fatigue. Duration of each task and frequency of efforts were determined using the level of effort to obtain a numerical result for comparison with the standard level. Results: The evaluated task was to remove paired bricks from the conveyor and transfer them to trailer truck by workers. The final results revealed that lower back tolerated the most amount of pressure (score=323, followed by the shoulders and wrist of the right hand (scores=313, which were assigned to the fatigue level. Therefore, the highest total fatigue of workload was imposed on these body parts. Conclusion: According to the results of this study, the upper limbs of workers incurred the highest burden in lifting bricks, and there was a in risk of WMSDS due to high workload. Therefore, it is recommended that working systems be improved through rotating work and reducing the number of transferred bricks to avoid risks caused by accumulation of fatigue.

Purpose: To implement two new features in the EGSnrc Monte Carlo system. The first is an option to account for photonuclear attenuation, which can contribute a few percent to the total cross section at the higher end of the energy range of interest to medical physics. The second is an option to use exact NIST XCOM photon cross sections. Methods: For the first feature, the photonuclear total cross sections are generated from the IAEA evaluated data. In the current, first-order implementation, after a photonuclear event, there is no energy deposition or secondary particle generation. The implementation is validated against deterministic calculations and experimental measurements of transmission signals. For the second feature, before this work, if the user explicitly requested XCOM photon cross sections, EGSnrc still used its own internal incoherent scattering cross sections. These differ by up to 2% from XCOM data between 30 keV and 40 MeV. After this work, exact XCOM incoherent scattering cross sections are an available option. Minor interpolation artifacts in pair and triplet XCOM cross sections are also addressed. The default for photon cross section in EGSnrc is XCOM except for the new incoherent scattering cross sections, which have to be explicitly requested. The photonuclear, incoherent, pair and triplet data from this work are available for elements and compounds for photon energies from 1 keV to 100 GeV. Results: Both features are implemented and validated in EGSnrc.Conclusions: The two features are part of the standard EGSnrc distribution as of version 4.2.3.2.

Numerous reports indicate that tumor-infiltrating lymphocytes (TILs) are a prognostic factor in various cancers and that they must be good biomarkers. However, the methods of evaluating TILs differ in each study; thus, there is not yet a standardized methodology for evaluating TILs. The purpose of this study is to evaluate the prognostic significance of tumor-infiltrating lymphocytes (TILs) in patients with colorectal cancer (CRC) using the new method proposed by the International TILs Working Group in breast cancer and to standardize the method of evaluating TILs in CRC. We retrospectively reviewed a database of 160 patients with Stage II or III CRC. The density of TILs was assessed by measuring the area occupied by mononuclear cells over the stromal area on hematoxylin and eosin (H-E)-stained sections. We set 42% as the cut-off percentage of the area occupied by TILs according to the receiver operating characteristic curve, and we classified patients into the high-TILs and the low-TILs groups. The rates of relapse-free survival (RFS) and overall survival (OS) in the high-TILs group were significantly higher than those in the low-TILs group. A multivariate analysis showed that the density of TILs was independently associated with RFS and OS. Moreover, the density of TILs assessed by an observer was significantly associated with the density of TILs assessed by the automated imaging software program. The new method for evaluating TILs, which was recommended by the International TILs Working Group in breast cancer, might be a useful predictive factor in colorectal cancer patients.

Associations between psychosocial work environment and excess weight have not been systematically addressed. The aim of this systematic review was to summarize the published evidence for the associations of psychosocial factors at work and long work hours with weight-related outcomes . Methods We conducted a search of Medline and Embase for all original articles published up to September 2012 using predefined keywords. After excluding studies with a definite selection bias, we included 39 articles. About 60% of the studies reported at least one positive association between psychosocial factors at work and a weight-related outcome. However, 76% of the tested associations were found to be non-significant. Furthermore, the associations were rather weak. Studies of higher quality tended to observe associations more often than those of lower quality. Positive associations were found more frequently (i) among women versus men, (ii) in cross-sectional versus longitudinal studies, and (iii) for overweight or obesity versus other outcomes. About 70% of the studies reported positive associations between long work hours and weight-related outcomes. All four studies that evaluated the association between working overtime and weight gain (three longitudinal and one cross-sectional), showed a positive association among men and two of them also observed associations among women. We found evidence for weak associations between psychosocial factors at work and excess weight. Associations were observed between long work hours, working overtime, and weight gain, especially among men. More cohort studies among non-obese baseline participants using appropriate analytical methods based on an elaborated hypothetical model are needed.

Objectives Low-back pain (LBP) is a substantial health challenge due to the risk for long-term sickness absence and early retirement. Several biomechanical exposures at work, including sitting, have been suggested to increase the risk for LBP. The objectives of this study were to determine (i) the extent to which temporal patterns and total amount of objectively measured sitting is associated with LBP intensity and (ii) whether selected modifiers influence these associations. Methods This cross sectional study uses baseline data from the Danish PHysical ACTivity cohort with Objective measurements (DPhacto) of physical activities in the cleaning, transport and manufacturing sectors. Peak intensity of LBP was collected by questionnaire on a 0-10 scale and sitting was expressed in terms of total duration and temporal pattern, ie, time spent in brief bursts (≤5 minutes), moderate periods (>5-≤20 minutes), and prolonged periods of sitting (>20 minutes); both during work and whole day (waking hours only). Associations were determined using linear regression in models accounting for moderation and confounding. Factors evaluated as moderators or confounders were assessed by questionnaire. Results The population consisted of 704 participants. No significant associations were found between total duration or temporal patterns of sitting and LBP intensity, neither during work nor for the whole day. Body mass index (BMI) significantly moderated the association between sitting and LBP; participants with a high and low BMI showing a negative and positive association, respectively. Conclusion Sitting was not independently associated with peak LBP intensity, suggesting other exposures are more powerful risk factors for LBP.

Full Text Available Burnout is a psychosomatic syndrome widely observed in Chinese medical workers due to the increasing cost of medical treatment, excessive workload, and excessive prescribing behavior. No studies have evaluated the interrelationship among occupational burnout, work-family conflict, social support, and job satisfaction in medical workers. The aim of this study was to evaluate these relationships among medical workers in southwest China.This cross-sectional study was conducted between March 2013 and December 2013, and was based on the fifth National Health Service Survey (NHSS. A total of 1382 medical workers were enrolled in the study. Pearson correlation analysis and general linear model univariate analysis were used to evaluate the relationship of work-family conflict, self-reported social support, and job satisfaction with burnout syndrome in medical workers.We observed that five dimensions of job satisfaction and self-reported social support were negatively associated with burnout syndrome, whereas three dimensions of work-family conflict showed a positive correlation. In a four-stage general linear model analysis, we found that demographic factors accounted for 5.4% of individual variance in burnout syndrome (F = 4.720, P<0.001, R2 = 0.054, and that work-family conflict, self-reported social support, and job satisfaction accounted for 2.6% (F = 5.93, P<0.001, R2 = 0.080, 5.7% (F = 9.532, P<0.001, R2 = 0.137 and 17.8% (F = 21.608, P<0.001, R2 = 0.315 of the variance, respectively. In the fourth stage of analysis, female gender and a lower technical title correlated to a higher level of burnout syndrome, and medical workers without administrative duties had more serious burnout syndrome than those with administrative duties.In conclusion, the present study suggests that work-family conflict and self-reported social support slightly affect the level of burnout syndrome, and that job satisfaction is a much stronger influence on burnout syndrome

Full Text Available Lighting is an essential element for modern life, promoting a sense of wellbeing for users. However, bad illumination may produce health problems such as headaches and fatigue, among other vision problems. For that reason, this paper proposes the development of a smartphone-based application to help in lighting evaluation to guarantee the compliance of illumination regulations and to help increase illuminance efficiency, reducing its energy consumption. To perform this evaluation, the smartphone can be used as a lighting measurement tool, evaluating those measurements through an intelligent agent based in rules capable of guiding the decision-making process. As a result, this tool allows the evaluation of the real working environment to guarantee lighting requirements, helping in the prevention of health problems derived from bad illumination and improving the lighting efficiency at the same time.

Increasing active travel (walking, bicycling, and public transport) is promoted as a key strategy to increase physical activity and reduce the growing burden of noncommunicable diseases (NCDs) globally. Little is known about patterns of active travel or associated cardiovascular health benefits in low- and middle-income countries. This study examines mode and duration of travel to work in rural and urban India and associations between active travel and overweight, hypertension, and diabetes. Cross-sectional study of 3,902 participants (1,366 rural, 2,536 urban) in the Indian Migration Study. Associations between mode and duration of active travel and cardiovascular risk factors were assessed using random-effect logistic regression models adjusting for age, sex, caste, standard of living, occupation, factory location, leisure time physical activity, daily fat intake, smoking status, and alcohol use. Rural dwellers were significantly more likely to bicycle (68.3% versus 15.9%; ptravelled to work by private transport, public transport, bicycling, and walking, respectively. In the adjusted analysis, those walking (adjusted risk ratio [ARR] 0.72; 95% CI 0.58-0.88) or bicycling to work (ARR 0.66; 95% CI 0.55-0.77) were significantly less likely to be overweight or obese than those travelling by private transport. Those bicycling to work were significantly less likely to have hypertension (ARR 0.51; 95% CI 0.36-0.71) or diabetes (ARR 0.65; 95% CI 0.44-0.95). There was evidence of a dose-response relationship between duration of bicycling to work and being overweight, having hypertension or diabetes. The main limitation of the study is the cross-sectional design, which limits causal inference for the associations found. Walking and bicycling to work was associated with reduced cardiovascular risk in the Indian population. Efforts to increase active travel in urban areas and halt declines in rural areas should be integral to strategies to maintain healthy weight and prevent

Unemployment can negatively impact quality of life among patients with schizophrenia. Employment status depends on ability, opportunity, education, and cultural influences. A clinician-rated scale of work readiness, independent of current work status, can be a valuable assessment tool. A series of studies were conducted to create and validate a Work Readiness Questionnaire (WoRQ) for clinicians to assess patient ability to engage in socially useful activity, independent of work availability. Content validity, test-retest and inter-rater reliability, and construct validity were evaluated in three separate studies. Content validity was supported. Cronbach's α was 0.91, in the excellent range. Clinicians endorsed WoRQ concepts, including treatment adherence, physical appearance, social competence, and symptom control. The final readiness decision showed good test-retest reliability and moderate inter-rater reliability. Work readiness was associated with higher function and lower levels of negative symptoms. Low positive and high negative predictive values confirmed the concept validity. The WoRQ has suitable psychometric properties for use in a clinical trial for patients with a broad range of symptom severity. The scale may be applicable to assess therapeutic interventions. It is not intended to assess eligibility for supported work interventions. The WoRQ is suitable for use in schizophrenia clinical trials to assess patient work functional potential.

To evaluate work satisfaction among Spanish nurses employed by English hospitals, as well as the influence of several social and work-related variables associated with satisfaction. We performed a cross-sectional study. All Spanish nurses (n=360) with a contract with any English hospital in April 2003 were included in the study. The self-administered and validated Font Roja work satisfaction questionnaire was used. The response rate was 78.6%. Overall work satisfaction among Spanish nurses was medium. The dimensions with higher work satisfaction were relationships with colleagues and superiors. The dimensions showing lowest work satisfaction were job satisfaction and professional competence. Statistically significant and positive associations were obtained between level of English, professional grade, shift pattern, working in the intensive care unit or accident and emergency department, time worked in English hospitals and degree of work satisfaction. Employers of Spanish nurses should try to increase job satisfaction and professional competence among these workers. Incentivation and professional promotion systems might help achieve this aim. Employers could also try to improve Spanish nurses' English level before contracts are signed and pay special attention to their needs during the first working year. Spanish nurses job satisfaction would also increase if they were allowed to choose their working shift and the unit or ward where they are going to work.

Burnout and work engagement are generally defined as psychological states but the methods used to measure these constructs are more in line with methods used to assess psychological traits. Thus, a new instrument called the Scale of Work Engagement and Burnout (SWEBO) measuring the state mood of burnout and work engagement was developed during the fall of 2007. The purpose of the present study was to evaluate the SWEBO using psychometrical methods. The sample consisted of 2,266 newly graduated Swedish nurses and teachers. Measurement models of both burnout and work engagement were evaluated using confirmatory factor analysis (CFA). Both burnout and work engagement were also tested for measurement invariance across occupation and age. The fit of the measurement model of burnout was satisfactory and it was invariant across both occupation and age. The measurement model of work engagement as initially defined did not fit the data satisfactorily. The model was therefore revised and reanalyzed. The revised model had a satisfactory fit and was invariant across occupation. Analysis of its invariance across age, however, gave ambiguous results that were difficult to interpret. The SWEBO presents a psychometrically sound alternative for measuring burnout and work engagement.

Past efforts by the Department of Energy (DOE), the Electric Power Research Institute (EPRI), the Nuclear Regulatory Commission (NRC), and others have provided sufficient technical information to enable the NRC to issue regulatory guidance for implementation of pressurized-water reactor (PWR) burnup credit; however, consideration of only the reactivity change due to the major actinides is recommended in the guidance. Moreover, DOE, NRC, and EPRI have noted the need for additional scientific and technical data to justify expanding PWR burnup credit to include fission product (FP) nuclides and enable burnup credit implementation for boiling-water reactor (BWR) spent nuclear fuel (SNF). The criticality safety assessment needed for burnup credit applications will utilize computational analyses of packages containing SNF with FP nuclides. Over the years, significant efforts have been devoted to the nuclear data evaluation of major isotopes pertinent to reactor applications (i.e., uranium, plutonium, etc.); however, efforts to evaluate FP cross-section data in the resonance region have been less thorough relative to actinide data. In particular, resonance region cross-section measurements with corresponding R-matrix resonance analyses have not been performed for FP nuclides. Therefore, the objective of this work is to assess the status and performance of existing FP cross-section and cross-section uncertainty data in the resonance region for use in burnup credit analyses. Recommendations for new cross-section measurements and/or evaluations are made based on the data assessment. The assessment focuses on seven primary FP isotopes (103Rh, 133Cs, 143Nd, 149Sm, 151Sm, 152Sm, and 155Gd) that impact reactivity analyses of transportation packages and two FP isotopes (153Eu and 155Eu) that impact prediction of 155Gd concentrations. Much of the assessment work was completed in 2005, and the assessment focused on the latest FP cross-section evaluations available in the

As detailed associations between personality and long work hours are unclear, we assessed associations between personality dimensions and overtime work among Japanese white-collar workers. From records of hours worked over 12 months by 267 office workers in an organization within the service industry, average overtime work hours per month and occurrence of excessive overtime was determined for each worker. Excessive overtime was defined as > 45 overtime work hours per month for at least one month. Responses to a questionnaire assessing socio-demographic and workplace-related factors and the Big Five personality test were analyzed. Associations between personality factors and overtime work were assessed by multivariate logistic regression analysis. Low Extraversion was associated with excessive overtime work (OR 2.02, 95%CI 1.02 - 4.02, P = 0.04). It is suggested that workers with low Extraversion can't share work when busy to avoid excessive overtime. Personality factors should be considered in studies evaluating work time. Moreover, strengthening communication among workers with low Extraversion may reduce excessive overtime work and associated health problems.
Cross-national research on contractor evaluation procedures in public works procurement

Kinoshita, Seiya; Sato, Naoyoshi; Matsumoto, Naoya

Contractor evaluation methods in Japan's public works procurement, beginning with construction business licensure, going through biennial preliminary firm rating, up to project-by-project prequalification and comprehensive point rating, were developed during the period when public works were mostly procured through designated competitive bidding. It is essential to focus attention on contractor evaluation methods for introducing different types of procurement procedures which enhance the use of technological capabilities held by private businesses. An overall review of contractor evaluation procedures should be conducted in view of the present situation, where the open competitive bidding has become mainly used in combination with comprehensive evaluation, as well as to allow for further diversification of procurement methods. In Western countries, improvements have been made for the past several years in contractor evaluation procedures with more emphasis on "Value for Money." Advanced efforts made by these countries will be useful as a reference for overhauling Japan's contractor evaluation system. This study conducts a comparative review of contractor evaluation procedures for public procurement in Western countries such as the United States, the United Kingdom and France by identifying similarities and differences between those of Japan and the above mentioned countries. This reveals that a contractor's technical or professional ability is looked at separately from its economic and financial standing in those countries studied, and there is no case like Japan in which those two factors are integrated into one for evaluation.

Epidemiological evidence suggests that work stress is associated with suicidal ideation (SI). However, only few studies in this area have drawn on well-established theoretical work stress models (i.e., the job-demand-control [JDC] model, the effort-reward-imbalance [ERI] model, and the model of organizational injustice [OJ]). Utilization of such models allows though for theory-based assessments and workplace interventions. Since evidence on those models' relationship with suicide-related outcomes is currently inconclusive (with regard to JDC), markedly sparse (OJ) or lacking (ERI), we aimed to provide additional or initial evidence. We drew on original data from six cross-sectional studies, which were conducted in four countries (i.e., South Korea, China, Australia, and Germany). Work stress was measured by established questionnaires and was categorized into tertiles. In each study, SI was assessed by either one or two items taken from validated scales. Associations of work stress with SI were estimated for each study and were pooled across studies using multivariate random-effects logistic modeling. In the pooled analyses (n=12,422) all three work stress models were significantly associated with SI with odds ratios fluctuating around 2. For instance, the pooled odds ratios for highest versus lowest work stress exposure in terms of job strain, OJ, and ERI equalled 1.91 (95% confidence interval [CI]=1.52, 2.41), 1.98 (95% CI=1.48, 2.65), and 2.77 (95% CI=1.57, 4.88), respectively. Patterns of associations were largely consistent across the individual studies. Our study provides robust evidence of a positive association between work stress and SI. Copyright © 2016 Elsevier Inc.

Full text: In this work, we present our analysis of the CREOLE experiment on the parameter by using the three-dimensional continuous energy code (MCNPS) and the last updated nuclear data evaluations. This experiment performed in the EOLE critical facility located at CEA-Cadarache, was dedicated to studies for both UO2 and UO2-PuO2 PWR type lattices covering the whole temperature range from 20 0 C to 300 0 C. We have developed an accurate model of the EOLE reactor to be used by the MCNP5 Monte Carlo code. This model guarantees a high level of fidelity in the description of different configurations at various temperatures taking into account their consequence on neutron cross section data and all thermal expansion effects. In this case, the remaining error between calculation and experiment will be awarded mainly to uncertainties on nuclear data. Our own cross section library was constructed by using NJOY99.259 code with point-wise nuclear data based on ENDF-BVII. JEFF3.1, JENDL3.3 and JENDL4 evaluation files. The MCNP model was validated through the axial and radial fission rate measurements at room and hot temperatures. Calculation-experiment discrepancies of the reactivity parameter were analyzed and the results have shown that the JENDL evaluations give the most consistent values. In order to specify the source of the relatively large difference between experiment and calculation due to ENDF-BVII nuclear data evaluation, the discrepancy in reactivity between ENDF-BVII and JENDL evaluations was decomposed using sensitivity and uncertainty analysis technique
EVALUATION OF THE WORKING ABILITY OF THE WORKERS SUFFERING FROM A CARDIOVASCULAR SYSTEM DISEASE

Directory of Open Access Journals (Sweden)

2000-11-01

Full Text Available The working ability evaluation is a process of numerous examinations, measurements and estimates that are done by a team of medical and other experts. It is utterly unacceptable to think that the opinion about someone's working ability is given by some individual specialist of any expert domain especially regarding the invalids' category since this can lead to either confusion or undesired conflicts between the patient and those who are professionally and legally qualified to evaluate his working ability. In order to carry out the medical part of the expertise for evaluating the working ability it is necessary have an accurate diagnosis of particular disease, an opinion whether the process is definite or can be improved by and adequate therapy in addition to the state of morphology and function of all the organs and systems essential for responding to the biological requirements of the working operations at a given job as well as the estimate of the functional ability of the organs or systems. The practical evaluation of the working ability also has to include the professional utilization factor, that is, it is necessary to determine the working operations' requirements as well as the conditions in which they are performed at a given job. Within the working ability it is necessary to take into consideration the psychosocial structure of the sick person, years of age, qualification and professional degree as well as the society's possibility to accept the proposals made by the medical and other experts. Tn judging the working ability of the patients having a cardiac disease it is indispensable to view every case separately since it always implies its own factors. The evaluation must be done in specially-qualified institutions having an adequate team of experts including a specialist of labor medicine, a cardiologist, a safety-at-work expert, a technologist, a psychologist, a social worker and other medical and non-medical staff.

This report documents the recent evaluation of the ²³⁶Pu, ²³⁷Pu, and ²³⁸Pu cross section sets. Nuclear data evaluation is the fundamental interface that takes measured nuclear cross section data and turns them into a continuous curve that 1) is consistent with other measurements and nuclear reaction theory/models, and 2) is required by down-stream users. All experiments that generate nuclear data need to include an evaluation step for their data to be broadly useful to the end users.

The effect of the decay data on the measured activation cross section is investigated carefully and testified by several examples. These decay data include the half-life of the product, γ branching ratio of the product and decay scheme. Present work shows that these effects must be considered carefully when evaluating the activation reaction cross section. Sometimes they are main reason for causing the discrepancies among the experimental data

Pelvic injuries following motor vehicle accidents (MVA) cause disability and affect work capabilities. This study evaluated functional, self-report, and medical-based factors that could predict work capacity as was reflected in a functional capacity evaluation (FCE) among persons who sustained a pelvic injury. It was hypothesized that self-reported functional status and bio-demographic variables would predict work capacity. Sixty-one community-dwelling adults previously hospitalized following a MVA induced pelvic injury. FCE for work performance was conducted using the Physical Work Performance Evaluation (PWPE). Additional data was collected through a demographics questionnaire and the Functional Status Questionnaire. All participants underwent an orthopedic medical examination of the hip and lower extremities. Most participants self-reported that their work capacity post-injury were lower than their job required. PWPE scores indicated below-range functional performance. Regression models predicted 23% to 51% of PWPE subtests. Participants' self-report of functioning (instrumental activities of daily living and work) and bio-demographic variables (gender and age) were better predictors of PWPE scores than factors originating from the medical examination. Results support the inclusion of FCE, in addition to self-report of functioning and medical examination, to evaluate work capacity among individuals' post-pelvic injury and interventions and discharge planning.

BACKGROUND: The Balance Evaluation Systems Test (BESTest) was recently created to allow the development of treatments according to the specific balance system affected in each patient. The Brazilian version of the BESTest has not been specifically tested after stroke. OBJECTIVE: To evaluate the intra- and inter-rater reliability and concurrent and convergent validity of the total score of the BESTest and BESTest sections for adults with hemiparesis after stroke. METHOD: The study included 16 subjects (61.1±7.5 years) with chronic hemiparesis (54.5±43.5 months after stroke). The BESTest was administered by two raters in the same week and one of the raters repeated the test after a one-week interval. Intraclass correlation coefficient (ICC) was calculated to assess intra- and interrater reliability. Concurrent validity with the Berg Balance Scale (BBS) and convergent validity with the Activities-specific Balance Confidence scale (ABC-Brazil) were assessed using Pearson's correlation coefficient. RESULTS: Both the BESTest total score (ICC=0.98) and the BESTest sections (ICC between 0.85 and 0.96) have excellent intrarater reliability. Interrater reliability for the total score was excellent (ICC=0.93) and, for the sections, it ranged between 0.71 and 0.94. The correlation coefficient between the BESTest and the BBS and ABC-Brazil were 0.78 and 0.59, respectively. CONCLUSIONS: The Brazilian version of the BESTest demonstrated adequate reliability when measured by sections and could identify what balance system was affected in patients after stroke. Concurrent validity was excellent with the BBS total score and good to excellent with the sections. The total scores but not the sections present adequate convergent validity with the ABC-Brazil. However, other psychometric properties should be further investigated. PMID:25003281
A re-evaluation of 32S(n,p) cross sections from threshold to 5 MeV

Fu, C.Y.

1989-01-01

Two evaluations of the 32 S(n,p) reaction cross sections, currently being used for the Nagasaki and Hiroshima dosimetry studies, yielded results that differ significantly. These two evaluations were reviewed and both were found to be quite old and without benefit of modern theoretical guidance and recent experimental data, hence inadequate in view of its relative importance for the present application. The necessity for a re-evaluation is further enhanced by the fact that: the present data search has uncovered a relatively high-quality data set that was not known previously, a generalized Bayes-theorem code is now available for averaging the various data sets with uncertainties and generating uncertainties for the results, effects on data combination of differing energy resolution in the various measurements can now be accounted for, and the ENDF/B-VI standards for 238 U(n,f) cross sections have become available for renormalizing two of the available data sets. The re-evaluation is performed to 5 MeV, the upper energy limit for the present purpose. 8 refs., 2 figs

2015-01-01

Objectives Investigating the potential pathways linking shift work and cardiovascular diseases (CVD), this study aimed to identify whether sleep disturbances mediate the relationship between shift work and the metabolic syndrome, a cluster of CVD risk factors. Design Cross-sectional study. Setting A tertiary-level, acute care teaching hospital in Southeastern Ontario, Canada. Participants Female hospital employees working a shift schedule of two 12 h days, two 12 h nights, followed by 5 days off (n=121) were compared with female day-only workers (n=150). Primary and secondary outcome measures Each of the seven components of the Pittsburgh Sleep Quality Index (PSQI) was measured. Of these, PSQI global score, sleep latency and sleep efficiency were examined as potential mediators in the relationship between shift work and the metabolic syndrome. Results Shift work status was associated with poor (>5) PSQI global score (OR=2.10, 95% CI 1.20 to 3.65), poor (≥2) sleep latency (OR=2.18, 95% CI 1.23 to 3.87) and poor (≥2) sleep efficiency (OR=2.11, 95% CI 1.16 to 3.84). Although shift work was associated with the metabolic syndrome (OR=2.29, 95% CI 1.12 to 4.70), the measured components of sleep quality did not mediate the relationship between shift work and the metabolic syndrome. Conclusions Women working in a rapid forward rotating shift pattern have poorer sleep quality according to self-reported indicators of the validated PSQI and they have a higher prevalence of the metabolic syndrome compared with women who work during the day only. However, sleep quality did not mediate the relationship between shift work and the metabolic syndrome, suggesting that there are other psychophysiological pathways linking shift work to increased risk for CVD.

The thermal radiative capture cross sections and resonance integrals of elements and isotopes with atomic numbers from 1 to 83 (as well as 232 Th and 238 U) have been re-evaluated by taking into consideration all known pertinent data published since 1979. This work has been undertaken as part of an IAEA co-ordinated research project on 'Prompt capture gamma-ray activation analysis'. Westcott g-factors for radiative capture cross sections at a temperature of 300K were computed by utilizing the INTER code and ENDF-B/VI (Release 8) library files. The temperature dependence of the Westcott g-factor is illustrated for 113 Cd, 124 Xe and 157 Gd at temperatures of 150, 294 and 400K. Comparisons have also been made of the newly evaluated capture cross sections of 6 Li, 7 Li, 12 C and 207 Pb with those determined by the k 0 method. (author)

Reactor cell analysis is the first step in determining reactor core behavior and is required in the reload licensing process. For best results, reactor cell analysis should be carried out with libraries of up to date, accurate cross sections produced with well described methods from standard evaluated nuclear data. At first step in this work were determined the library structure for RECORD and THERMOS and were prepared the cross sections libraries using the NJOY nuclear data processing system and the ENDF-B/IV evaluated nuclear data. These libraries were used by the codes and some samples were perform, the result show some differences against the results obtained using the previous libraries. By other hand the libraries contain various adjustments to correct for deficiencies in nuclear data or analytical methods. These adjustments doesn't have any documentation, although some of them were identified in this work. (Author). 25 refs, 78 figs, 55 tabs

Full Text Available BACKGROUND: The evaluation of the ability for return to work among patients after myocardial infarction (MI is subject to controversy. Understanding various factors, which may affect return to work process, will help in promoting effective communication between physicians and patients. Return to work is dependent on such factors as patients’ functional capacity, MI expansion, cardiac muscle function, some psychiatric variables, job satisfaction, economic status, and age. In this study, we aimed to assess the frequency of return to work after first MI attack, and factors affecting it. METHODS: This was a follow-up study performed in Yazd, Iran from September 2007 until September 2010 on 200 patients suffering from their first MI attack. Patients were assessed 6 months and 1-year after MI regarding their cardiac function. Job satisfaction was evaluated by Direct Support Professional job satisfaction questionnaire. RESULTS: Seventy-seven percent of MI patients returned to work after 1-year. Mean time for return to work was 46.00 ± 4.12 days. Sixty percent of patients returned to work during the first 50 days after MI and 50% of them during 40 days after MI. The most common reason for not returning to work was patient’s decision. CONCLUSION: This study showed that a considerable numbers of patients returned to work after 1-year. The only factors which affected the rate of return to work were left ventricular function after MI and job satisfaction. Keywords: Myocardial Infarction, Return to Work, Left Ventricular Function, Job Satisfaction

The objective of this work has been to improve the knowledge of the thermal cross sections of the fissile nuclei as a step toward providing a standard data base for the nuclear industry. The methodology uses a form of the Adler-Adler multilevel-fission theory and Breit-Wigner multilevel-scattering theory. It incorporates these theories in a general nonlinear least-squares (LSQ) fitting program SIGLEARNThe analysis methodology in this work was applied to the thermal data on 235 U. A reference data file has been developed which includes most of the known data of interest. The first important result of this work is the assessment of the shape uncertainties of the partial cross sections. The results of our studies lead to the following values and error estimates for 235 U g factors in a thermal (20.44 0 C) energy spectrum: g/sub f/ = 0.97751 (+-0.11%); g/sub γ/ = 0.98230 (+-0.14%). A second important result of this study is the development of a recommended set of 2200 m/s (0.0253 eV) values of the parameters and the probable range of further adjustment which might be made. The analysis also provides the result of a common interpretation of energy-dependent absolute cross-section data of different measurements to yield a consistent set of experimental 0.0253 eV values with rigorous error estimates. It also provides normalization factors for relative fission and capture cross sections on a common basis with rigorous error estimates. The results of these analyses provide a basis for deciding what new measurements would be most beneficial. The most important of these would be improved direct capture data in the thermal region

Kokoouline, V.; Richardson, W.

Uncertainties in theoretical calculations may include: • Systematic uncertainty: Due to applicability limits of the chosen model. • Random: Within a model, uncertainties of model parameters result in uncertainties of final results (such as cross sections). • If uncertainties of experimental and theoretical data are known, for the purpose of data evaluation (to produce recommended data), one should combine two data sets to produce the best guess data with the smallest possible uncertainty. In many situations, it is possible to assess the accuracy of theoretical calculations because theoretical models usually rely on parameters that are uncertain, but not completely random, i.e. the uncertainties of the parameters of the models are approximately known. If there are one or several such parameters with corresponding uncertainties, even if some or all parameters are correlated, the above approach gives a conceptually simple way to calculate uncertainties of final cross sections (uncertainty propagation). Numerically, the statistical approach to the uncertainty propagation could be computationally expensive. However, in situations, where uncertainties are considered to be as important as the actual cross sections (for data validation or benchmark calculations, for example), such a numerical effort is justified. Having data from different sources (say, from theory and experiment), a systematic statistical approach allows one to compare the data and produce “unbiased” evaluated data with improved uncertainties, if uncertainties of initial data from different sources are available. Without uncertainties, the data evaluation/validation becomes impossible. This is the reason why theoreticians should assess the accuracy of their calculations in one way or another. A statistical and systematic approach, similar to the described above, is preferable.

The researchers conducted a cross-sectional survey to determine the relationship between handling heavy items during pregnancy and spontaneous abortion among working women in South Korea. One thousand working women were selected from a database of those eligible for maternity benefits under the National Employment Insurance Plan. Study results showed that handling heavy items during pregnancy was associated with an increased risk of spontaneous abortion after adjusting for general characteristics of the participants and their work environment. A collective effort is needed on the parts of employers, employees, occupational health nurses, and the government to protect working women from lifting heavy items while pregnant.

Full Text Available This paper presents a model to evaluate the performance of a solar-powered organic Rankine cycle (ORC. The system was evaluated in Jackson, MS, using five dry organic working fluids, R218, R227ea, R236ea, R236fa, and RC318. The purpose of this study is to investigate how hourly temperature change affects the electricity production and exergy destruction rates of the solar ORC, and to determine the effect of the working fluid on the proposed system. The system was also evaluated in Tucson, AZ, to investigate the effect of average hourly outdoor temperatures on its performance. The potential of the system to reduce primary energy consumption and carbon dioxide emissions is also investigated. A parametric analysis to determine how temperature and pressure of the organic working fluid, the solar collector area, and the turbine efficiency affect the electricity production is performed. Results show that the ORC produces the most electricity during the middle of the day, when the temperatures are the highest and when the solar collectors have the highest efficiency. Also, R-236ea is the working fluid that shows the best performance of the evaluated fluids. An economic analysis was performed to determine the capital cost available for the proposed system.

Psoriasis can have cumulative physical and psychosocial effects preventing sufferers from achieving their full-life potential. Few studies have addressed the impact of psoriasis on work-related characteristics. To evaluate the impact of psoriasis on education prospects and work limitations in patients with moderate-to-severe psoriasis. This study was conducted in 29 dermatology centres across Italy. Information was collected by questionnaire during office visits. A total of 787 patients (64% male, aged 50 years) completed the questionnaire. At the time of the survey, mean Psoriasis Area and Severity Index (PASI) score and disease duration were 10 and 19 years respectively. Current smokers had higher PASI scores compared to non-smokers (10.8 vs. 9.4, P = 0.02). Plaque psoriasis was the most frequently described (91.2%). Fifty-five percent of patients had limited expectations of career progression. Similarly, in 42% of cases, psoriasis reduced the prospects of improvement in employment status and 35% of patients reported having reduced earning potential. Approximately 60% of patients reported that psoriasis localized to their hands or feet caused work limitations, whilst in about 25%, it caused them to quit their job. Approximately 37% of patients reported having lost between 3-10 work days in the past 3 months due to clinical assessment or treatment. Logistic regression revealed that gender, low standard of education, number of localizations, shame, anger and self-esteem were predictors significantly associated with limitations in work. Moderate-to-severe psoriasis has a profound negative impact on the employment capacity of patients in Italy. Psoriasis also contributes to days lost from work, affects job opportunity, career prospects and revenue potential. © 2013 European Academy of Dermatology and Venereology.
Evaluation of computational models and cross sections used by MCNP6 for simulation of electron backscattering

Energy Technology Data Exchange (ETDEWEB)

This work evaluates the accuracy of the single-event (SE) and condensed-history (CH) models of electron transport in Monte Carlo simulations of electron backscattering from thick layers of Be, C, Al, Cu, Ag, Au and U at incident electron energies from 200 eV to 15 MeV. The CH method is used in simulations performed with MCNP6.1, and the SE method is used in simulations performed with an open-source single-event code MCNelectron written by the author of this paper. Both MCNP6.1 and MCNelectron use mainly ENDF/B-VI.8 library data, but MCNelectron allows replacing cross sections of certain types of interactions by alternative datasets from other sources. The SE method is evaluated both using only ENDF/B-VI.8 cross sections (the “SE-ENDF/B method”, which is equivalent to using MCNP6.1 in SE mode) and with an alternative set of elastic scattering cross sections obtained from relativistic (Dirac) partial-wave (DPW) calculations (the “SE-DPW method”). It is shown that at energies from 200 eV to 300 keV the estimates of the backscattering coefficients obtained using the SE-DPW method are typically within 10% of the experimental data, which is approximately the same accuracy that is achieved using MCNP6.1 in CH mode. At energies below 1 keV and above 300 keV, the SE-DPW method is much more accurate than the SE-ENDF/B method due to lack of angular distribution data in the ENDF/B library in those energy ranges. At energies from 500 keV to 15 MeV, the CH approximation is roughly twice more accurate than the SE-DPW method, with the average relative errors equal 7% and 14%, respectively. The energy probability density functions (PDFs) of backscattered electrons for Al and Cu, calculated using the SE method with DPW cross sections when energy of incident electrons is 20 keV, have an average absolute error as low as 4% of the average PDF. This error is approximately twice less than the error of the corresponding PDF calculated using the CH approximation. It is concluded

The titanium isotopes (n,p) cross sections are based upon renormalized experimental data or deduced from statistical model calculations where measurements were not available. Some of these cross sections, notably the 46 Ti (n,p), 47 Ti (n,p) and 48 Ti (n,p), which find wide use as dosimetry indicators, are compared here with the corresponding ENDF/BIV dosimetry file data. The (n,p) elemental cross section is constructed from the weighted isotopic components. Our evaluation and the corresponding ENDF/BIV data are compared showing the great difference between both results, especially below 10 MeV. Moreover the new data exhibit some structure characteristics of the 47 Ti (n,p) cross section. The present Ti (n,p) data are intended to be included in the ENDF/BV evaluation

To explore the situation of older nurses approaching retirement with regard to their retirement planning, and the relationship of their retirement planning behaviour with the job environment and job satisfaction under their current employment arrangements and other work-related variables. Nurse shortage has become a global phenomenon that can be alleviated by retaining older nurses in service. The Chinese government proposed the "Incremental Delay Retirement Age Policy." However, older nurses face delayed retirement but lack retirement plans. A cross-sectional questionnaire survey was conducted among a convenience sample of older retiring nurses (n = 152; 84.92% response rate) recruited from every department of four large general hospitals in Changchun, Jilin Province from June to August 2016. The majority of the respondents presented poor retirement planning (n = 122, 80.3%). The independent variables of information exchange with patients, teamwork and personal growth and development explained approximately 16.6% of the variance in retirement planning. Nurse-patient communication and personal growth and development can promote retirement planning, but teamwork is negatively related to retirement planning. Retirement planning by Chinese older nurses is related to certain work-related variables. However, many other work-related variables were not associated with retirement planning and require further research. Overall, Chinese older retiring nurses must improve their retirement planning practices. © 2017 John Wiley & Sons Ltd.

The prevalence and impact of musculoskeletal conditions are predicted to rapidly escalate in the coming decades. Effective strategies are required to minimise 'evidence-practice', 'burden-policy' and 'burden-service' gaps and optimise health system responsiveness for sustainable, best-practice healthcare. One mechanism by which evidence can be translated into practice and policy is through Models of Care (MoCs), which provide a blueprint for health services planning and delivery. While evidence supports the effectiveness of musculoskeletal MoCs for improving health outcomes and system efficiencies, no standardised national approach to evaluation in terms of their 'readiness' for implementation and 'success' after implementation, is yet available. Further, the value assigned to MoCs by end users is uncertain. This qualitative study aimed to explore end users' views on the relevance of musculoskeletal MoCs to their work and value of a standardised evaluation approach. A cross-sectional qualitative study was undertaken. Subject matter experts (SMEs) with health, policy and administration and consumer backgrounds were drawn from three Australian states. A semi-structured interview schedule was developed and piloted to explore perceptions about musculoskeletal MoCs including: i) aspects important to their work (or life, for consumers) ii) usefulness of standardised evaluation frameworks to judge 'readiness' and 'success' and iii) challenges associated with standardised evaluation. Verbatim transcripts were analysed by two researchers using a grounded theory approach to derive key themes. Twenty-seven SMEs (n = 19; 70.4 % female) including five (18.5 %) consumers participated in the study. MoCs were perceived as critical for influencing and initiating changes to best-practice healthcare planning and delivery and providing practical guidance on how to implement and evaluate services.

This study aimed to explore the association between shift work and work-related injuries. We collected data on workers from an electronics factory. This cross-sectional study included 13,610 subjects, who were assessed based on a self-reported questionnaire about their shift work experiences, work-related injuries, and other covariates. Multiple logistic regression models were used to evaluate the associations between shift work and work-related injuries and were estimated using the odds ratio. We found that the current and past shift workers, compared to non-shift workers, were associated with a 2.7- and 1.7-fold higher risk of work-related injury. There was a dose-response relationship between shift work duration and work-related injury among current female shift workers. Shift work increased the risk of work-related injuries, and the impact could be different depending on gender.

Translate the Essentials of Magnetism II© (EOMII; Dutch Nurses' Association, Utrecht, The Netherlands) and assess its psychometric properties in a culture different from its origin. The EOMII, developed in the USA, measures the extent to which organizations/units provide healthy, productive and satisfying work environments. As many healthcare organizations are facing difficulties in attracting and retaining staff nurses, the EOMII provides the opportunity to assess the health and effectiveness of work environments. A three-phased (respectively N = 13, N = 74 and N = 2542) combined descriptive and correlational design was undertaken for translation and evaluation validity and psychometric qualities of the EOMII for Dutch hospitals (December 2009-January 2010). We performed forward-backward translation, face and content validation via cross-sectional survey research, and semi-structured interviews on relevance, clarity, and recognizability of instruments' items. Psychometric testing included principal component analysis using varimax rotation, item-total statistics, and reliability in terms of internal consistency (Cronbach's α) for the total scale and its subscales. Face validity was confirmed. Items were recognizable, relevant and clear. Confirmatory factor analysis indicated that five of eight subscales formed clear factors. Three original subscales contained two factors. Item-total correlations ranged from 0.43 to 0.83. One item correlated weakly (0.24) with its subscale. Cronbach's α for the entire scale was 0.92 and ranged from 0.58 to 0.92 for eight subscales. Dutch-translated EOMII (D-EOMII) demonstrated acceptable reliability and validity for assessing hospital staff nurses' work environment. The D-EOMII can be useful and effective in identifying areas in which change is needed for a hospital to pursue an excellent work environment that attracts and retains well-qualified nurses. © 2013 International Council of Nurses.

The impact of long working hours on health has been of major concern since the late 19th Century. Working hours are again increasing in the US. An overview of historical, sociological, and health-related research presented at an international conference on long working hours is discussed as an introduction to a special section in this issue. Research indicates that long working hours are polarizing along class lines with professionals working regular though longer hours and less well-educated workers having fewer though more irregular hours. Extended and irregular hours are associated with acute reactions such as stress and fatigue, adverse health behavior such as smoking, and chronic outcomes such as cardiovascular and musculoskeletal disorders. Improved methodologies are needed to track exposure to long working hours and irregular shifts longitudinally. Research should focus on the adverse impact that sleep-deprived and stressed workers may have on the health of the public they serve. A variety of protective efforts should be undertaken and evaluated. Copyright (c) 2006 Wiley-Liss, Inc.

Full Text Available Increasing active travel (walking, bicycling, and public transport is promoted as a key strategy to increase physical activity and reduce the growing burden of noncommunicable diseases (NCDs globally. Little is known about patterns of active travel or associated cardiovascular health benefits in low- and middle-income countries. This study examines mode and duration of travel to work in rural and urban India and associations between active travel and overweight, hypertension, and diabetes.Cross-sectional study of 3,902 participants (1,366 rural, 2,536 urban in the Indian Migration Study. Associations between mode and duration of active travel and cardiovascular risk factors were assessed using random-effect logistic regression models adjusting for age, sex, caste, standard of living, occupation, factory location, leisure time physical activity, daily fat intake, smoking status, and alcohol use. Rural dwellers were significantly more likely to bicycle (68.3% versus 15.9%; p<0.001 to work than urban dwellers. The prevalence of overweight or obesity was 50.0%, 37.6%, 24.2%, 24.9%; hypertension was 17.7%, 11.8%, 6.5%, 9.8%; and diabetes was 10.8%, 7.4%, 3.8%, 7.3% in participants who travelled to work by private transport, public transport, bicycling, and walking, respectively. In the adjusted analysis, those walking (adjusted risk ratio [ARR] 0.72; 95% CI 0.58-0.88 or bicycling to work (ARR 0.66; 95% CI 0.55-0.77 were significantly less likely to be overweight or obese than those travelling by private transport.

The 7. workshop on Nuclear Measurements, Evaluations and Applications (NEMEA) focused on international collaboration in nuclear data by hosting the kick-off meeting of the pilot project of the Collaborative International Evaluated Library Organisation (CIELO). CIELO aims at fostering nuclear data advances by using the joint expertise of the nuclear data community under the auspices of the OECD Nuclear Energy Agency. The workshop aimed at status reviews of planned and completed contributions and related developments for the CIELO pilot isotopes. The workshop further sought to facilitate in-depth discussions on nuclear data issues which are being addressed in the framework of European Commission projects like ERINDA, EUFRAT, ANDES and CHANDA. The 7. workshop on Nuclear Measurements, Evaluations and Applications (NEMEA) provided an opportunity for the Collaborative International Evaluated Library Organisation (CIELO) to meet and advance its objectives to improve our understanding of neutron reactions on key isotopes that are especially important in nuclear applications, especially in the area of criticality safety and reactors. CIELO is focusing initially on six nuclides ( 1 H, 16 O, 56 Fe, 235 U, 238 U and 239 Pu). These nuclides are important in the aforementioned applications, and despite decades of work many open questions remain to be solved. In some cases, the existing evaluations need improvement because the underlying experimental measurements are either lacking or contradictory. In other cases, nuclear theory work is needed to better advance predictions. In yet other cases, information from cross-section measurements is proving difficult to reconcile with information from integral nuclear criticality experiments or neutron shielding experiments. The main challenges to be faced are as follows: For oxygen, new work is needed to better define the total and elastic cross-sections at lower energies and neutron scattering angular distributions.

The Swedish Social Insurance Administration has developed a new assessment tool for sickness insurance. This study is a part of the initial evaluation of the application, called the Assessment of Work Performance, Structured Activities, and focuses on evaluation of the psychometric properties of social validity, content validity, and utility. This was a qualitative study using semi-structured telephone interviews with occupational therapists. A convenience sample was used and participants who fulfilled inclusion criteria (n = 15) were interviewed. Data were analyzed using content analysis with a directed approach. The results indicate that the application provides valuable information and that it is socially valid. Assessors found work tasks suitable for a diverse group of clients and reported that clients accepted the assessments. Improvements were suggested, for example, expanding the application with more work tasks. The instrument has benefits; however, further development is desired. The use of a constructed environment in assessments may be a necessary option to supplement a real environment. But depending on organizational factors such as time and other resources, the participants had different opportunities to do so. Further evaluations regarding ecological validity are essential to ensure that assessments are fair and realistic when using constructed environments. Implications for rehabilitation This study indicates that assessment in a constructed environment can provide a secure and protected context for clients being assessed. Psychometric evaluations are a never-ending process and this assessment instrument needs further development. However, this initial evaluation provides guidance in development of the instrument but also what studies to give priority to. It is important to evaluate social validity in order to ensure that clients and assessors perceive assessment methods fair and meaningful. In this study, participants found the work tasks

Mine drivage is evaluated in underground coal mines in the Kuzbass and factors which influence drivage advance rate and cost. Mine drivage in the Kuzbass in 1982 is described: 1,706.3 km of workings were driven by explosive fracturing and heading machines, 853.8 km of workings were driven with mechanized rock handling systems, 205.8 km with rock handling by loaders, 532.1 km were driven by heading machines. The average cross-section of workings driven in the Kuzbass ranged from 4 to 12 m/SUP/2; from 8 to 12% of workings had a cross-section exceeding 12 m/SUP/2. Strata control systems used in mine drivage are evaluated: 22.8% of workings was supported by steel arched supports, 20.3% by roof bolts, 0.07% by concrete supports or tubbings, 47.5% by timber props and 9.2% by other support systems. Statistical data on mine drivage of mine roadways, development workings, ventilation tunnels, inclined workings and coal chutes in the Kuzbass are given in 7 tables. Mine drivage in selected coal mines of the basin is evaluated: drivage systems, materials handling, mine haulage, strata control, transport of materials, safety.

On the occasion of a new measurement of the excitation function of the reaction 103 Rh(n,n') 103m Rh in the energy range between 5.69 and 12.0 MeV performed at the present institute in collaboration wit the PTB Braunschweig, the cross section of this reaction, which is part of the International Reactor Dosimetry Field (IRDF-90), was re-evaluated. Whereas the energy range of the evaluation, namely from threshold to 20 MeV, was kept unchanged with respect to IRDF-90, the underlying data base was extended by the experiment mentioned as well as by another measurement, and revised with regard to judgement and normalization of older data in the light of recent information. Based on the experimental data upgraded in this way, new model calculations were carried out, which in the energy region 14 - 20 MeV served to supplement the experimental cross sections for this evaluation. The cross sections and their uncertainties were evaluated in energy groups with widths of 0.2 to 1.0 MeV, and the relative correlation matrix of the evaluated cross sections at the different energies was calculated. The results presented here supersede the corresponding values published in Physics Data 13-5 and included to the IRDF-90. (author). 26 refs, 4 figs, 6 tabs

Purpose: To retrospectively assess the sensitivity and specificity of three-dimensional (3D) 16-section computed tomography (CT) in the evaluation of vessels, pelvicalyceal system, and ureters in living renal donors, with surgical findings as the reference standard. Materials and methods: This was a HIPAA-compliant study. Institutional review board approval was obtained for the review of subjects' medical records and data analysis, with waiver of informed consent. Forty-six renal donors (18 men, 28 women; mean age, 42 years) were examined with 16-section CT. Two blinded reviewers independently studied renal vascular and urographic anatomy of each donor CT scans by fist using 3D images alone, then transverse images alone, and finally transverse and 3D data set. Image quality, degree of diagnostic confidence, and time used for review were recorded. Sensitivity and specificity were calculated. Results: For 3D images, transverse images, and transverse in conjunction with 3D data sets, the respective sensitivity and specificity of CT in evaluation of accessory arteries by reviewer 1 were 100% and 100%, 89% and 100%, and 100% and 100%, and those by reviewer 2 were 89% and 97%, 89% and 100%, and 89% and 100%; the respective sensitivity and specificity in evaluation of venous anomalies by reviewer 1 were 100% and 98%, 100% and 98%, and 100% and 98%, and those by reviewer 2 were 100% and 98%, 100% and 95%, and 100% and 98%. For focused comprehensive assessment of renal donors with 3D scans alone, a reviewer on average (average of reviewers 1 and 2) used 2.4 minutes per scan, demonstrated full confidence in 93%, and rated the quality as excellent in 76%. Conclusion: For focused assessment of renal vascular and urographic anatomy, review of 3D data set alone provides high sensitivity and specificity with regard to findings seen at surgery. (author)

Working as a physician at an oncology department has some distinctive characteristics that may lead to a stressful work environment. The present study was conducted to provide a nationwide description of the work conditions of all oncologists in Denmark. By comparing the results of the present study with those of a similar study carried out in 2006, the aim was furthermore to elucidate changes in the psychosocial work environment over time. From May to September 2009, 330 physicians employed at six oncology centres and seven community based oncology departments were invited to participate in a survey based on the short version of the COPSOQ II questionnaire. The results were compared with data from a representative section of Danish employees and with data from the 2006 survey. Two hundred and twenty of the 330 invited physicians returned the questionnaire (response rate 67%). Concerning the aspects quantitative demands, work pace, emotional demands, influence, burnout and stress, the oncologists reported worse work conditions than the average Danish employee. However, with regard to possibilities for development, meaning of work and commitment to workplace, the oncologists reported better work conditions. Between 2006 and 2009, substantial improvement was seen concerning several of the assessed work environment aspects within the group of young physicians at the oncology centres. Though substantial improvement of the work conditions has been achieved between 2006 and 2009, certain aspects of the psychosocial work environment at Danish oncology departments still require attention.

Full Text Available This study aimed to explore the association between shift work and work-related injuries. We collected data on workers from an electronics factory. This cross-sectional study included 13,610 subjects, who were assessed based on a self-reported questionnaire about their shift work experiences, work-related injuries, and other covariates. Multiple logistic regression models were used to evaluate the associations between shift work and work-related injuries and were estimated using the odds ratio. We found that the current and past shift workers, compared to non-shift workers, were associated with a 2.7- and 1.7-fold higher risk of work-related injury. There was a dose-response relationship between shift work duration and work-related injury among current female shift workers. Shift work increased the risk of work-related injuries, and the impact could be different depending on gender.

Following a series of recent cross section evaluations on tungsten isotopes performed at Oak Ridge National Laboratory (ORNL), this paper presents the validation work carried out to test the performance of the evaluated cross sections based on lead-slowing-down (LSD) benchmarks conducted in Grenoble. ORNL completed the resonance parameter evaluation of four tungsten isotopes - 182,183,184,186W - in August 2014 and submitted it as an ENDF-compatible file to be part of the next release of the ENDF/B-VIII.0 nuclear data library. The evaluations were performed with support from the US Nuclear Criticality Safety Program in an effort to provide improved tungsten cross section and covariance data for criticality safety sensitivity analyses. The validation analysis based on the LSD benchmarks showed an improved agreement with the experimental response when the ORNL tungsten evaluations were included in the ENDF/B-VII.1 library. Comparison with the results obtained with the JEFF-3.2 nuclear data library are also discussed.

The aim of this cross-sectional study was to evaluate the mental health of student teachers, to analyse the extent to which they feel prepared for their profession by the university curriculum and to investigate patterns of coping with occupational stress. A sample of 481 German student teachers was investigated using two standardised instruments: GHQ-12 (General Health Questionnaire) and AVEM (Arbeitsbezogenes Verhaltens- und Erlebensmuster), an occupational stress and coping questionnaire describing four patterns of work-related coping behaviour. In addition, we asked how well the student teachers felt that the curriculum prepared them for their profession. Forty-four per cent of the student teachers report impaired mental health in the second teacher training period, indicated by a GHQ value equal to or over the cut-off of four. The AVEM responses revealed more than 40% showing risk patterns (A or B) compared to only 26.3% displaying a healthy coping style (G), while 32.8% demonstrate an unambitious style (S). These GHQ values are inversely correlated with the extent to which student teachers feel prepared for their work by the university curriculum. Our data indicate a problematic stress level for student teachers in the second training phase (high exposure to health risks and unfavourable coping styles). Since teaching is clearly an extremely demanding job, it is vital that teacher training systems contribute towards protecting the health of teachers by focusing on fostering healthy personal attitudes and equipping young teachers with coping styles and skills that will better prepare them for the challenges facing them in their daily work. Self-care health management should also be part of the teacher training curriculum.

To describe care worker-reported quality of care and to examine its relationship with staffing variables, work environment, work stressors, and implicit rationing of nursing care. Cross-sectional study. National, randomly selected sample of Swiss nursing homes, stratified according to language region and size. A total of 4311 care workers of all educational backgrounds (registered nurses, licensed practical nurses, nurse aides) from 402 units in 155 nursing homes completed a survey between May 2012 and April 2013. Care worker-reported quality of care was measured with a single item; predictors were assessed with established instruments (eg, Practice Environment Scale-Nurse Working Index) adapted for nursing home use. A multilevel logistic regression model was applied to assess predictors for quality of care. Overall, 7% of care workers rated the quality of care provided as rather low or very low. Important factors related to better quality of care were higher teamwork and safety climate (odds ratio [OR] 6.19, 95% confidence interval [CI] 4.36-8.79); better staffing and resources adequacy (OR 2.94, 95% CI 2.08-4.15); less stress due to workload (OR 0.71, 95% CI 0.55-0.93); less implicit rationing of caring, rehabilitation, and monitoring (OR 0.34, 95% CI 0.24-0.49); and less rationing of social care (OR 0.80, 95% CI 0.69-0.92). Neither leadership nor staffing levels, staff mix, or turnover was significantly related to quality of care. Work environment factors and organizational processes are vital to provide high quality of care. The improvement of work environment, support in handling work stressors, and reduction of rationing of nursing care might be intervention points to promote high quality of care in nursing homes.

2015-03-01

Full Text Available Shipbuilding industry includes many different industry branches in itself so various kind of work accidents occur. These work accidents often cause serious injuries and also deaths. It is a crucial thing to prevent or minimize these accidents. In order to reduce work accidents in shipyards, the most hazardous activities are needed to be determined and then, shipyard management must work on it in order to remove these hazard sources. In this study, pin jig work unit, where the curved parts are mounted on adjustable pin jigs, was considered. At first, the work activities and operations of pin jig work station were identified and they were classified as main and sub risk criterions. Then, pair comparison scales were built and these risk criterions were evaluated by experts who have been working for a shipyard located in Turkey. As a result of the evaluations of the experts, the risk weights of the activities carried out at pin jig work unit were defined by using fuzzy AHP method. Therefore, it is aimed for the shipyard management to take some precautions at pinjig work unit on the risky operations before failures happen.

2014-02-01

The aims of the study were to (a) validate N2N Healthy Work Environment tool, (b) assess the healthiness of work environments as perceived by nurses themselves and (c) identify the factors associated with Italian nurses' perception of work environment healthiness. The linguistic and cultural adaptation of USA-N2N Healthy Work Environments was achieved through a process of forward/backward translation. Content validity was assessed by three expert nurses. The stability of the instrument was checked with a test/retest evaluation. The instrument psychometric properties, the confirmatory factor analysis as well the healthiness of the work environment and its determinant factors were evaluated with a sample of 294 nurses. The content and face validity of the N2N Healthy Work Environment instrument was confirmed. The instrument demonstrated good internal consistency (α of 0.82), excellent stability values (ρ > 0.70) and high levels of acceptability (response rate: 96.4 %). The confirmatory factor analysis has corroborated the existence of two factors as documented in the original instrument (Mays et al. in J Nurs Manag 19:18-26, 2011). Eighty-seven (29.6 %) nurses perceived the work environment where they work as "healthy". Working under a functional model of care delivery (χ(2) 24.856, p 0.000) and being responsible for one project or more (χ(2) 5.256, p 0.021) were associated with healthy environments. The instrument--valid and reliable, short in the number of items, easy to understand and based on international standards--allows a systematic assessment of the healthiness of the environment and might provide not only the opportunity to evaluate the effects of new organizational models and interventions, but also the possibility to activate a process of self-analysis and a process of ongoing review. The instrument can be used to systematically check the healthiness of Italian working environments, allowing for organizational diagnosis, targeted interventions and

The compiled values are listed and plotted for reference without adjustments. From these collected results those values for which adequate supplementary information on nuclear constants, standards and experimental errors is provided are selected for use in reaction-by-reaction evaluations. These data are adjusted as needed to account for recent revisions in the nuclear constants and cross section standards. The adjusted results are subsequently transformed to equivalent cross sections at 14.7 MeV for the evaluation process. The evaluations are performed utilizing a least-squares method which considers correlations between the experimental data. 440 refs., 41 figs., 46 tabs

Pleural involvement of interlobar fissure by a tumor is one of the most important factors in the clinical diagnosis of lung cancer. A positive finding of incomplete interlobar fissure of the lung influences not only the surgical procedure but also the prognosis. The aim of this retrospective study was to investigate the usefulness of thin-section computed tomography (CT) compared with conventional CT in the detection of pleural invasion of the interlobar fissure by lung cancer or incomplete interlobar fissure, and the results of surgery, according to the involvement of the pleural surface. We reviewed 90 patients whose tumors were adjacent to the interlobar fissure of the lung through conventional CT scans and subsequent thoracotomy. A comparison of diagnoses based on the findings of thin-section CT and pathologic examination showed that thin-section CT was 94% accurate for pleural invasion of the interlobar fissure, and 100% for incomplete interlobar fissure. Conventional CT, however, was only 63% accurate for pleural invasion of the interlobar fissure and 31% for incomplete interlobar fissure. This leads us to conclude that thin-section CT is helpful in the accurate evaluation of pleural invasion of the interlobar fissure and in the findings of incomplete interlobar fissure in lung cancer for patients in whom tumors are adjacent to the interlobar fissure on conventional CT findings.

We have evaluated the cross sections for neutrons with incident energies from 20 to 80 MeV on {sup 12}C for the JENDL high-energy file. The total cross sections were determined by a generalized least-squares method with available experimental data. The cross sections of elastic and inelastic scattering to the first 2{sup +} were evaluated with the theoretical calculations. The optical potentials necessary for these calculations were derived using a microscopic approach by Jeukenne-Lejeune-Mahaux. For the evaluation of double differential emission cross sections (DDXs), we have developed a code system SCINFUL/DDX in which total 35 reactions including the 3-body simultaneous breakup process (n+{sup 12}C {yields} n+{alpha}+{sup 8}Be) can be taken into consideration in terms of a Monte Carlo method, and have calculated the DDXs of all light-emissions (A{<=}4) and heavier reaction products. The results for protons, deuterons, and alphas showed overall good agreement with experimental data. The code is also applicable for calculations of total and partial kerma factors. Total kerma factors calculated for energies from 20 to 80 MeV were compared with the measurements and the other latest evaluations from the viewpoints of medical application and nuclear heating estimation.

Emotional exhaustion among healthcare workers is a widely investigated, well-recognized problem, the incidence of which has recently been linked to work environment factors, particularly work/family conflict. However, another environmental feature that may be equally influential, but that is more amenable to nurse manager action, remains less recognized: shift schedule flexibility. This study's main purposes were to assess variations in work schedule flexibility between Swiss acute care hospital units, and to investigate associations between psychosocial work environment (e.g. work schedule flexibility) and self-reported emotional exhaustion among registered nurses. This is a secondary analysis of data collected for the multi-center observational cross-sectional Match RN study, which included a national sample of 23 hospitals and 1833 registered nurses across Switzerland. Overall, self-reported work schedule flexibility among registered nurses was limited: 32% of participants reported little or no influence in planning their own shifts. Work schedule flexibility (β -0.11; CI -0.16; -0.06) and perceived nurse manager ability (β -0.30; CI -0.49; -0.10) were negatively related to self-reported emotional exhaustion. Work-family conflict (β 0.39; CI 0.33; 0.45) was positively correlated to emotional exhaustion. The study results indicate that managerial efforts to improve working environments, including special efforts to improve work schedule flexibility, might play an important role in promoting nurses' emotional health.

Work Ability Index (WAI) is a well-known and valid self-report tool that has been widely used in various studies to identify and avoid early retirement and work-related disability. Nevertheless, very few studies have been carried out to evaluate work ability in Iran. We aimed to investigate the WAI and the effect of work-related stress on it among Iranian workers. A cross-sectional, descriptive and analytic study was carried out among 449 workers from five working sectors in three big cities of Iran. Work ability and work-related stress were measured using the Persian version of WAI and the Persian version of Health and Safety Executive Stress Indicator Tool. More than a third of the workers surveyed (34.70%) did not have an appropriate level of work ability (WAI work-related stress and the mean score of WAI. Furthermore, the variables of body mass index, sleep quality, exercise activity, job tenure, and three subscales of work-related stress including demands, supervisor support, and role were significant predictors of WAI. According to the results of this study, the interventional programs must be focused on improving supervisors support, eliminating ambiguity and conflicts in the role of workers in their job and organization, reducing job demands, improving sleep quality, and increasing exercise activity.

to evaluate the association between psychological demands, control over the work and the reduction of work ability of nursing professionals. this cross-sectional study involved 498 nursing professionals of a university hospital in the State of Rio Grande do Sul, Brazil. Data collection was carried out in 2009 using the Brazilian versions of the Work Ability Index and Job Stress Scale, with logistic regression models used for the data analysis. the prevalence of 43.3% for reduced work ability and 29.7% for high-strain in the job (high psychological demand and low control) were observed. The chances for professionals presenting reduced work ability under high-strain were higher and significant when compared to those classified as being under low-strain, even after adjusting for potential confounders, except for age and gender. a high prevalence of reduced work ability was observed. This evidence indicates the need for investigation and detailed analysis of the psychosocial aspects of the professionals with regard to the health/disease process of nursing professionals.

Maternal work has been identified as one of the factors that affect exclusive breastfeeding in the first six months of life. In Ghana, mothers engaged in the formal sector of employment are unable to exclusively breastfeed after maternity leave because facilities at their work places and conditions of work do not support exclusive breastfeeding. Even though maternal work and exclusive breastfeeding does not seem well matched, not all maternal work are incompatible with the practice of exclusive breastfeeding. This study seeks to identify the features of maternal work associated with exclusive breastfeeding in Effutu Municipal in the Central Region of Ghana. To achieve the above aim, I discuss the different types of maternal work, their characteristics, and how the work may influence exclusive breastfeeding. The study is a community based cross-sectional study involving 225 mother-infant pairs attending community based Child Welfare Clinics in Effutu Municipal, Ghana. Data were collected through face-to-face structured interviews and focus group discussions over a period of five months in 2015. Data on breastfeeding is based on the breastfeeding practice in the 24 h preceding the survey. Chi-square test is used to identify strength of association between the features of maternal work and exclusive breastfeeding practice. The exclusive breastfeeding rate among mothers with infants between the ages of 0 - 5 months is 72%. The mean and median number of breastfeeds per day is 11 ± 2.7 and 13.5 respectively. A significant difference in exclusive breastfeeding was established between mothers in the formal (16%) and informal (84%) sectors of employment ( p = 0.020). The study also established a significant difference in breastfeeding frequency between mothers in the formal (9%) and informal (91%) sectors of employment ( p = 0.001). There was also a significant difference in breastfeeding frequency among respondents that go to work with their infant (64

Maximum oxygen consumption shows the maximum oxygen rate of muscle oxygenation that is acceptable in many cases, to measure the fitness between person and the desired job. Given that medical emergencies are important, and difficult jobs in emergency situations require people with high physical ability and readiness for the job, the aim of this study was to evaluate the maximum oxygen consumption, to determine the ability of work type among students of medical emergencies in Qazvin in 2016. This study was a descriptive - analytical, and in cross-sectional type conducted among 36 volunteer students of medical emergencies in Qazvin in 2016. After necessary coordination for the implementation of the study, participants completed health questionnaires and demographic characteristics and then the participants were evaluated with step tests of American College of Sport Medicine (ACSM). Data analysis was done by SPSS version 18 and U-Mann-Whitney tests, Kruskal-Wallis and Pearson correlation coefficient. Average of maximum oxygen consumption of the participants was estimated 3.15±0.50 liters per minute. 91.7% of medical emergencies students were selected as appropriate in terms of maximum oxygen consumption and thus had the ability to do heavy and too heavy work. Average of maximum oxygen consumption evaluated by the U-Mann-Whitney test and Kruskal-Wallis, had significant relationship with age (p<0.05) and weight groups (p<0.001). There was a significant positive correlation between maximum oxygen consumption with weight and body mass index (p<0.001). The results of this study showed that demographic variables of weight and body mass index are the factors influencing the determination of maximum oxygen consumption, as most of the students had the ability to do heavy, and too heavy work. Therefore, people with ability to do average work are not suitable for medical emergency tasks.

The aims of this study were to identify the work ability (WA) of breast cancer (BC) survivors during the course of their illness, and the relationships between personal-, disease-, and work-related factors, and their WA. This is a cross-sectional survey study. One hundred fifty-one participants with the response rate of 88.9% were recruited from the community in 2014 and 2015. BC survivors' WA was at its highest before diagnosis, and then dropped to the lowest during treatment. Although their current WA had improved, it has not bounced back to that before diagnosis. The resignation rate was 35.8%. Factors positively associated with current WA included (a) age and year of diagnosis, (b) physical and psychological health and (c) WA before diagnosis or during treatment, working years, work control and mastery. However, compliance with appropriate healthy eating habits and believing in personal health controlled by chance were negatively associated with current WA. Furthermore, the participants would more likely to have higher current WA if they (a) were more optimistic with good stress management; (b) currently were not receiving treatment or other illnesses; (c) perceived less effects of their health problems, physical workloads or their cancer diagnoses on their work and (d) perceived continue to work in the next 2 years, with good ability to handle physical and mental work. This study confirmed that most BC survivors continued to work after their diagnoses. The factors affecting their WA were multifactorial. It is important to enhance their positive thinking.

This fiscal year, based on the examination result about the evaluation energy range of heavy element unresolved resonance cross sections, the upper energy limit of the energy range, where ultra-fine group cross sections are produced, was raised to 50 keV, and an improvement of the group cross section processing system was promoted. At the same time, reflecting the result of studies carried out till now, a function producing delayed neutron data was added to the general-purpose group cross section processing system , thus the preparation of general purpose group cross section processing system has been completed. On the other hand, the energy structure, data constitution and data contents of next generation group cross section set were determined, and the specification of a 151 groups next generation group cross section set was defined. Based on the above specification, a concrete library format of the next generation cross section set has been determined. After having carried out the above-described work, using the general-purpose group cross section processing system , which was complete in this study, with use of the JENDL-3. 2 evaluated nuclear data, the 151 groups next generation group cross section of 92 nuclides and the ultra fine group resonance cross section library for 29 nuclides have been prepared. Utilizing the 151 groups next generation group cross section set and the ultra-fine group resonance cross-section library, a bench mark test calculation of fast reactors has been performed by using an advanced lattice calculation code. It was confirmed, by comparing the calculation result with a calculation result of continuous energy Monte Carlo code, that the 151 groups next generation cross section set has sufficient accuracy.

Long working hours have been associated with an increased risk of cardiovascular disease, but its relationship with hypertension remains unclear. The objective of this study is to examine the relationship between overtime and presence of hypertension using data from a large-scale multi-company study in Japan. Participants were 52 365 workers of four companies that provided both health-checkup data and self-reported data on overtime worked. Hypertension was defined as systolic blood pressure ≥140 mmHg, diastolic blood pressure ≥90 mmHg, and/or the use of antihypertensive drug. Logistic regression analysis was performed to determine the odds ratio for hypertension for each category of overtime work (work: 17.5, 12.0, 11.1 and 9.1% for the shortest (work and presence of hypertension.

The recent crisis of 99 Mo production by nuclear reactors caused an unexpected worldwide 99m Tc shortening, forcing the international scientific community to find alternative production routes for these vital nuclides. One of the possibilities is to replace the current reactor-based method with the accelerator-based one. The aim of this work is the experimental evaluation of the 96 Zr(α,n) 99 Mo reaction, using the well known stacked foil technique with natural Zr targets, in the energy range 33-8 MeV. The results were compared with the published experimental values, finding good agreement in the trend of the cross section but at higher peak value. The results refer to 100% enriched 96 Zr target. The cross section values measured in the different irradiations show excellent agreement and indicate that the ideal energy range for 99 Mo production is 13-25 MeV. In comparison with the literature, there is good agreement in the trend of the cross section but at higher peak value. The 96 Zr(α,n) 99 Mo reaction is an interesting alternative production route of 99 Mo aimed at the realization of 99 Mo/ 99 mTc generators. Using enriched 96 Zr as target, 99 Mo is the only radioactive Mo-isotope produced, while using natural Zr as target, the resulting 99 Mo still has an high radioisotopic purity (only the radioactive 93 Mo is co-produced), but a lower specific activity. In both cases no Tc-nuclides are directly produced in target and the high purity 99m Tc results only from the decay of 99 Mo
Working Memory in Written Composition: An Evaluation of the 1996 Model

Directory of Open Access Journals (Sweden)

Ronald T. Kellogg, , , &

2013-10-01

Full Text Available A model of how working memory, as conceived by Baddeley (1986, supports the planning of ideas, translating ideas into written sentences, and reviewing the ideas and text already produced was proposed by Kellogg (1996. A progress report based on research from the past 17 years shows strong support for the core assumption that planning, translating, and reviewing are all dependent on the central executive. Similarly, the translation of ideas into a sentence does in fact require also verbal working memory, but the claim that editing makes no demands on the phonological loop is tenuous. As predicted by the model, planning also engages the visuo-spatial sketchpad. However, it turns out to do so only in planning with concrete concepts that elicit mental imagery. Abstract concepts do not require visuo-spatial resources, a point not anticipated by the original model. Moreover, it is unclear the extent to which planning involves spatial as opposed to visual working memory. Contrary to Baddeley’s original model, these are now known to be independent stores of working memory; the specific role of the spatial store in writing is uncertain based on the existing literature. The implications of this body of research for the instruction of writing are considered in the final section of the paper.

It is a well recognized understanding that workers whose voice needs to be heard should be actively encouraged as full participants and involved in the early design stages of new ergonomic work system which encompass the development and implementation of new tools, workplaces, technologies or organizations. This paper presents a novel participatory strategy to evaluate three key psychological factors which are respectively mental fatigue, spiritual stress, and emotional satisfaction in work system design based on a modified version of Participatory Ergonomics (PE). In specific, it integrates a PE technique with a formulation view by combining the parallel development of PE strategies, frameworks and functions throughout the coverage of the entire work system design process, so as to bridge the gap between qualitative and quantitative analysis of psychological factors which can cause adverse or advantageous effects on worker's physiological and behavioral performance.

The activity was carried out due to the modification of the heating in the HeaTiNG-02 test section. Modification of the heater needs to be done to overcome the obstacles that arise as part of the test section is used. Constraint that often arises is the fall of the heating source with super khantal material when it reaches a certain temperature. To mitigate the super khantal position is initially converted into a vertical position horizontal. The change from vertical to horizontal position on super khantal cause any deformities in refractory fire brick which serves as a support super khantal. Manufacture of refractory design fire brick formation and mechanical strength evaluation performed using CATIA V5 R20 software. Evaluation of fireproof rock mechanics to be based on the mechanical properties of alumina as a refractory material of fire brick. The results of the analysis have a fire brick design stress greater than the bend strength alumina materials, so that the necessary checks before and after the experiment as well as the replacement of refractory fire brick if something is broken. Translational greatest displacement 0.453 mm at a temperature of 1575 K did not give any meaningful form. Thus the refractory fire brick design can be used as heating source support in the HeaTiNG-02 test section with checks before and after the operation. (author)

Six primary health care centers in rural Uganda. To compare the quality of tuberculosis (TB) evaluation for men and women presenting to primary health care facilities in high-burden settings. Cross-sectional study using indicators derived from the International Standards of Tuberculosis Care (ISTC) to compare the quality of TB evaluation services provided to men and women. Of 161 230 patient visits between January 2009 and December 2010, 112 329 (69.7%) were women. We considered 3308 (2.1%) patients with cough ≥2 weeks as TB suspects, of whom 1871 (56.6%) were women. Female TB suspects were less likely to be referred for sputum smear examination (45.9% vs. 61.6%, P ISTC (33.0% vs. 45.6%, P ISTC-recommended care (RR 0.79, 95%CI 0.72-0.86, P < 0.001). Strategies to ensure that women receive appropriate TB evaluation could provide a valuable opportunity for increasing case detection while also promoting equitable and universal access to care.

To report the moderating effects of work-related conditions and interactive family-care-giving variables, including mutuality and preparedness, on caregiver role strain and mental health for family caregivers of patients with dementia. Few studies have examined the interrelationships among caregivers' working conditions, care-giving dynamics and caregiver well-being. Cross-sectional, correlational study. Data were collected by self-completed questionnaires from 176 primary family caregivers of patients with dementia in Taiwan from May 2005-January 2006. Caregiver role strain and mental health were analysed by multiple regressions using a hierarchical method to enter independent variables and two- and three-way interaction terms after controlling for caregiver age and gender, employment status, and work flexibility and the simple effect of each independent variable. More preparedness was associated with less role strain for family caregivers with less work/care-giving conflict. More care-giving demand was associated with poorer mental health only for caregivers with low work/care-giving conflict and with average and low preparedness, but not high preparedness. For family caregivers with less work/care-giving conflict, more preparedness decreased role strain and maintained mental health even when care-giving demand was high. These results provide a knowledge base for understanding complex family caregiver phenomena and serve as a guide for developing interventions. Future studies with longitudinal follow-ups are suggested to explore actual causal relationships. © 2012 Blackwell Publishing Ltd.

Objectives To investigate if participation in workplace health promotion (WHP) depends on the work environment. Methods Questionnaire data on participation in WHP activities (smoking cessation, healthy diet, exercise facilities, weekly exercise classes, contact with health professionals, health screenings) and the work environment (social support, fatiguing work, physical, quantitative and emotional demands, job control and WHP availability setting) were collected cross-sectionally in 2010 in a representative sample (n=10 605) of Danish workers. Binary regression analyses of the association between work environment characteristics and participation in WHP were conducted and adjusted for age, gender and industry. Results WHP offered during leisure time was associated with lower participation in all measured activities compared with when offered during working hours. Low social support and fatiguing work were associated with low participation in WHP. No associations with participation in WHPs were observed for physical work or quantitative demands, work pace or job strain. However, high physical demands/low job control and high emotional demands/low job control were associated with low participation. Conclusions Lower participation in WHP was associated with programmes during leisure, low social support, very fatiguing work and high physical or emotional demands with low job control. This suggests that to obtain proper effect of health promotion in a workplace setting, a good work environment is essential. PMID:27279474

1997-01-01

To establish diagnostic criteria for small solitary pulmonary nodules, the findings of thin-section computed tomography (CT) were compared with pathological findings. We evaluated thin-section CT images and compared them with pathological findings in 23 specimens of resected benign lesions less than 20 mm in diameter located in the peripheral region. The thin-section CT images were reconstructed using 2 mm thick sections taken by TCT-900S, HELIX (Toshiba, Tokyo) and were examined with two different windows and level settings. In every case, the surgical specimens were sliced transversely to correlate with the CT findings. The thin-section CT images were classified into two types; solid and air-containing types. The former consisted of benign pulmonary tumors, granulomas and some focal fibrosis, while the latter all consisted of focal fibrosis. Both types were difficult to distinguish from peripheral lung cancer based only on margin analysis of the lesion, but analysis of how pulmonary vessels relate to the lesion can allow benign pulmonary lesions to be distinguished from peripheral lung cancer.

This study consolidates and evaluates information and data obtained from a coal mining company's return to work program called the Work Therapy Program. Organizational information and economic and statistical data were available for the study based on the company's records. Analysis of the data included descriptive statistics such as total injuries, the frequency rate of injuries, total days away from work due to injury, average days away per employee, and severity rates. A cost-benefit analysis was conducted to determine if the Program was economically beneficial to the company. Data from an opinion survey of the management at the mine where the Program was first instituted was used to determine the perceptions of mine management with respect to the Work Therapy Program. Conclusions were that the Work Therapy Program was economically beneficial to the Company and that the Program resulted in a significant reduction in compensable injuries. The Program did not significantly reduce days away from work due to mine injury. Perceptions of mine management were mostly positive

We study the sources of systematic errors in the measurement of the W → lν cross-sections at the LHC. We consider the systematic errors in both the total cross-section and acceptance for anticipated experimental cuts. We include the best available analysis of QCD effects at NNLO in assessing the effect of higher order corrections and PDF and scale uncertainties on the theoretical acceptance. In addition, we evaluate the error due to missing NLO electroweak corrections and propose which MC generators and computational schemes should be implemented to best simulate the events.

The relationship between long working hours and harmful alcohol consumption reported in the literature is equivocal. This study aimed to investigate this relationship in a methodologically rigorous fashion. A cross-sectional analysis of a large cohort study of Australian and New Zealand nurses and midwives was undertaken. Psychometrically robust standardised assessments of alcohol consumption and problems and other key variables were elicited using an electronic survey. Crude and adjusted logistic regression models using complete case and multistage multiple imputed data were employed. The study included 4419 participants, 3552 from Australia and 867 from New Zealand. Long working hours were common, with 33.2% working 40-49 h/week and 7.5% working ≥50 h/week. Overall, 13.9% engaged in harmful daily drinking. Significant associations between long working hours and harmful daily alcohol consumption was seen in crude and adjusted complete case and imputed logistic regression models. In the adjusted model with imputed data, the odds of harmful daily drinking increased by 1.17 (95% confidence interval: 1.01, 1.36) between work long hours. Since the late 1970s, the average hours worked by full-time employees in Australia has increased. Unless these long working hours can be curbed, workforce policies and programmes aimed at prevention, supportive and empathetic intervention, and recovery need to be instigated; both to protect patients and the nurses and midwives themselves.

The need of efficient resource management and full-time accessibility to resources has increased with the development of industry, resulting in the increase of shift workers. Previous researches of past decades show that there are various health effects on shift workers. However, the definition and the form of shift work have varied from each research and occupational harmful factors except for shift work have not been excluded completely in previous researches. Therefore, in this research, we tried to find out the effect of shift work focusing on the hypertension. To complement previously mentioned weakness of other researches, we performed our research on participants to whom we could minimize other risk factors excluding shift work. This research examined 1,953 petrochemical plant male workers (shift work 1,075, day worker 878) who did medical checkup from 1st Jan. 2014 to 31th Dec. 2014 in a general hospital located in Ulsan, based on their medical records and questionnaires. With the questionnaire, we found out their basic information including age, social status, occupational history, and we took their physical measurements. Compared to day workers, shift workers' odds ratio of developing hypertension was 1.31 (95% CI 0.98-1.75). After adjusting confounding variables, adjusted odds ratio for entire subjects was 1.51 (95% CI 1.11-2.06). Also, for subjects who were in continuous service for over 20 years, odds ratio was 1.51 (95% CI 1.08-2.11). Shift workers had a higher chance of hypertension than day workers do. Particularly, the longer the workers work continuously, the risk of hypertension getting higher.

High efficiency particulate air (HEPA) filtration technology is commonly used in Department of Energy (DOE) facilities that require control of radioactive particulate matter (PM) emissions due to treatment or management of radioactive materials. Although HEPA technology typically makes use of glass fiber media, metal and ceramic media filters are also capable of filtering efficiencies beyond the required 99.97%. Sintered metal fiber filters are good candidates for use in DOE facilities due to their resistance to corrosive environments and resilience at high temperature and elevated levels of relative humidity. Their strength can protect them from high differential pressure or pressure spikes and allow for back pulse cleaning, extending filter lifetime. Use of these filters has the potential to reduce the cost of filtration in DOE facilities due to life cycle cost savings. ASME AG-1 section FI has not been approved due to a lack of protocols and performance criteria for qualifying section FI filters. The Institute for Clean Energy Technology (ICET) with the aid of the FI project team has developed a Section FI test stand and test plan capable of assisting in the qualification ASME AG-1 section FI filters. Testing done at ICET using the FI test stand evaluates resistance to rated air flow, test aerosol penetration and resistance to heated air of the section FI filters. Data collected during this testing consists of temperature, relative humidity, differential pressure, flow rate, upstream particle concentration, and downstream particle concentration. (authors)

Detailed analysis indicated that true stress (σ)-true plastic strain (ε) and work hardening behaviour of 9Cr–1Mo steel in two different forms, i.e. 20 mm plate and thick section tubeplate forging can be adequately described by Voce equation and Kocks–Mecking approach in the temperature range 300–873 K. The steel exhibited two-stage work hardening in the variations of instantaneous work hardening rate (θ = dσ/dε) and θσ with stress. The variations in σ–ε, work hardening parameters, θ–σ and θσ–σ with temperature exhibited three distinct temperature regimes. Good correlations between the predicted tensile properties using Voce equation and the respective experimental values along with analogy between Voce equation and Kocks–Mecking approach have been demonstrated for the steel. The differences in σ–ε, work hardening parameters, θ–σ and θσ–σ observed between plate and tubeplate forging have been ascribed to the effects associated with initial microstructures for the two product forms of the steel.

Helminths are one of the major health problems of working donkeys, often with heavy worm burden and contributing to their early demise and/or reduction in their work output. Cross-sectional and longitudinal studies were conducted to investigate the current infection prevalence and level of strongyles infection donkeys would acquire through different seasons in the mid-lowland agro-ecological zones of Ethiopia. For this purpose, faecal samples from 206 (cross-sectional study) and 102 (longitudinal study) randomly selected donkeys were directly collected from the rectum and analysed. For the longitudinal study, the 102 donkeys dewormed at the end of main rainy season, beginning of October, were monitored for the level of strongyle infection they would acquire during subsequent dry and short rainy seasons. The cross-sectional study of 206 donkey has revealed an overall infection prevalence of 89.3% (95% confidence interval (CI) = 84.4, 92.9). Donkeys in the lowland zone showed a significantly higher strongyle infection prevalence (P = 0.0126) and mean eggs per gramme of faces (EPG) (P = 0.001; 2775 EPG) compared to donkeys in the midland zone (980.8 EPG). Age, sex and body condition did not have any significant effect on either the infection prevalence or level of infection (P > 0.05). The longitudinal study has shown a significantly lower strongyle infection prevalence (P = 0.003) and level of infection donkeys acquired (P = 0.001) in the subsequent dry and short rainy seasons compared to the main rainy season following October deworming. However, these values were not significantly different between the two agro-ecological zones (P > 0.05). This study clearly showed that parasitic infections are primarily acquired during the main rainy season when pasture/herbage coverage is relatively better, and the environment is conducive for parasites survival and development. On the other hand, the finding of majority of donkeys shedding low or no eggs during the

This report reviews the major activities and accomplishments of the Organic Research Section in 1984 and presents the 1985 work program. The three major areas of the Section's research work are non-metallic materials which includes applications and uses of plastics, petroleum products, coatings and elastomers; reactor waste management; and activity transport/decontamination of nuclear systems. In 1984, 50% of the Section's resources were used on studies in support of nuclear generation, 13% on reactor waste, and 37% on general activities and work in support of utilization, transmission and distribution, and thermal and hydraulic programs. About 60% of the section's work was supported by transfer and revenue funds as a result of urgent short-term work requirements which resulted in 68% of the work falling into the technical investigation, consulting and testing categories
Modelisation of the fission cross section

2013-03-01

The neutron cross sections of four nuclear systems (n+ 235 U, n+ 233 U, n+ 241 Am and n+ 237 Np) are studied in the present document. The target nuclei of the first case, like 235 U and 239 Pu, have a large fission cross section after the absorption of thermal neutrons. These nuclei are called 'fissile' nuclei. The other type of nuclei, like 237 Np and 241 Am, fission mostly with fast neutrons, which exceed the fission threshold energy. These types of nuclei are called 'fertile'. The compound nuclei of the fertile nuclei have a binding energy higher than the fission barrier, while for the fissile nuclei the binding energy is lower than the fission barrier. In this work, the neutron induced cross sections for both types of nuclei are evaluated in the fast energy range. The total, reaction and shape-elastic cross sections are calculated by the coupled channel method of the optical model code ECIS, while the compound nucleus mechanism are treated by the statistical models implemented in the codes STATIS, GNASH and TALYS. The STATIS code includes a refined model of the fission process. Results from the theoretical calculations are compared with data retrieved from the experimental data base EXFOR. (author) [fr

Job stress is one of the factors that increase the likelihood of turnover. Intent to leave work is one of the most accurate predictors of turnover. This cross-sectional study was created to evaluate the intent of nurses working at hospitals to continue working and to determine the relationship between job stress and intent to stay at work. The subjects were 514 female hospital nurses aged 21-58 years old, who had worked full time at the study hospitals for at least 1 year. Data were collected using a self-administered questionnaire, which included sections on demographic characteristics, the Thai version of the Job Content Questionnaire (JCQ), and intent to stay at work. Multiple regression analysis was used to identify factors related to intent to stay at work. The prevalences of high job strain and low intent to stay at work were 17.5 and 22.4%, respectively. The mean (SD) scores of the nurses for psychological job demand, decision latitude, workplace social support, and intent to stay at work were 33.5 (4.4), 70.7 (6.9), 23.8 (2.8), and 14.6 (2.9), respectively. Multiple regression analysis indicated that intent to stay at work was significantly correlated with only supervisor support among the nurses with high-strain jobs and with coworker support in nurses with active jobs. The findings suggest that different job types need different sources of social support in the workplace. Proactive steps by nurse managers to increase workplace social support might lead to an increase in intent to stay and reduce nursing turnover in hospitals and possibly other settings.

For the calculation of neutron spectra in cold and super thermal sources scattering laws for a variety of liquid and solid cyrogenic materials were evaluated and prepared for use in deterministic and Monte Carlo transport calculations. For moderator materials like liquid and solid H 2 O, liquid He, liquid D 2 O, liquid and solid H 2 and D 2 , solid CH 4 and structure materials such as Al, Bi, Pb, ZrHx, and graphite scattering law data and cross sections are available. The evaluated data were validated by comparison with measured cross sections and comparison of measured and calculated neutron spectra as far as available. Further applications are the calculation of production and transport and storing of ultra cold neutrons (UCN) in different UCN sources. The data structures of the evaluated data are prepared for the common S N -transport codes and the Monte Carlo Code MCNP. (orig.)

The purpose of the study was to assess the level of job satisfaction of dental nurses in ambulatory care and to explore the impact of aspects of working atmosphere on and their association with job satisfaction. This cross-sectional study was based on a job satisfaction survey. Data were collected from 612 dental nurses working in 106 dental care practices. Job satisfaction was measured with the 10-item Warr-Cook-Wall job satisfaction scale. Working atmosphere was measured with five items. Linear regression analyses were performed in which each item of the job satisfaction scale was handled as dependent variables. A stepwise linear regression analysis was performed with overall job satisfaction and the five items of working atmosphere, job satisfaction, and individual characteristics. The response rate was 88.3%. Dental nurses were satisfied with 'colleagues' and least satisfied with 'income.' Different aspects of job satisfaction were mostly associated with the following working atmosphere issues: 'responsibilities within the practice team are clear,' 'suggestions for improvement are taken seriously,' 'working atmosphere in the practice team is good,' and 'made easier to admit own mistakes.' Within the stepwise linear regression analysis, the aspect 'physical working condition' (β = 0.304) showed the highest association with overall job satisfaction. The total explained variance of the 14 associated variables was 0.722 with overall job satisfaction. Working atmosphere within this discrete sample of dental care practice seemed to be an important influence on reported working condition and job satisfaction for dental nurses. Because of the high association of job satisfaction with physical working condition, the importance of paying more attention to an ergonomic working position for dental nurses to ensure optimal quality of care is highlighted. © 2015 John Wiley & Sons A/S.

Chadwick, M.B.

1998-01-01

The authors review recent work at Los Alamos to evaluate neutron, proton, and photonuclear cross section up to 150 MeV (to 250 MeV for protons), based on experimental data and nuclear model calculations. These data are represented in the ENDF format and can be used in computer codes to simulate radiation transport. They permit calculations of absorbed dose in the body from therapy beams, and through use of kerma coefficients allow absorbed dose to be estimated for a given neutron energy distribution. For radiation protection, these data can be used to determine shielding requirements in accelerator environments, and to calculate neutron, proton, gamma-ray, and radionuclide production. Illustrative comparisons of the evaluated cross section and kerma coefficient data with measurements are given

1982-01-01

The capture cross section of gold is now generally accepted as the principal reference standard, and therefore in this review only gold is considered. Recent measurements of the gold capture cross section in the unresolved region are discussed and compared with the ENDF/B-V evaluation. It is concluded that in the energy interval 100 to 2000 keV the present uncertainty in the evaluation is +-8%, in the interval 2 to 3.5 MeV the uncertainty is +-4%, in ther interval 3.5 to 14 MeV more measurements are needed before a realistic error can be assigned, and from 14 to 15 MeV the uncertainty is +-10%. Several recommendations for future work have been made

Back pain has been identified as a common cause of disability in the working population. Automotive mechanics habitually use awkward back posture in their course of manual activity and hence may be at risk of work-related back pain. To investigate the prevalence, pattern and severity of back pain among automotive maintenance mechanics, as well as the personal and job variables associated with or predicting occurrence of back pain. Using a cross-sectional design, information about self-reported back pain and the associated variables were collected among 684 randomly recruited automotive mechanics. Prevalence of back pain was 76.02%; with the majority experiencing low back pain. 63.3% of the workers reported they limited their activity due to the back pain. Older workers (>50 years), daily work lasting ≥5 hours duration, no more than primary education, being normal weight, frequent use of kneeling and sustained postures, and lack of knowledge of ergonomic postures were associated with increased prevalence of back pain. Lack of job autonomy, inadequate task clarity, heavy physical work load, manual material handling, strenuous posture, noisy environment, vibrations, work schedule and inadequate auxiliary support were also associated with increased prevalence of back pain among the mechanics. Work-related back pain is prevalent among automotive maintenance mechanics. Work-related back pain is high among automotive maintenance mechanics. Workstation policy and legislation on reduction of risks with combined health literacy and ergonomic education programs in this occupational group are imperative.

To investigate if participation in workplace health promotion (WHP) depends on the work environment. Questionnaire data on participation in WHP activities (smoking cessation, healthy diet, exercise facilities, weekly exercise classes, contact with health professionals, health screenings) and the work environment (social support, fatiguing work, physical, quantitative and emotional demands, job control and WHP availability setting) were collected cross-sectionally in 2010 in a representative sample (n=10 605) of Danish workers. Binary regression analyses of the association between work environment characteristics and participation in WHP were conducted and adjusted for age, gender and industry. WHP offered during leisure time was associated with lower participation in all measured activities compared with when offered during working hours. Low social support and fatiguing work were associated with low participation in WHP. No associations with participation in WHPs were observed for physical work or quantitative demands, work pace or job strain. However, high physical demands/low job control and high emotional demands/low job control were associated with low participation. Lower participation in WHP was associated with programmes during leisure, low social support, very fatiguing work and high physical or emotional demands with low job control. This suggests that to obtain proper effect of health promotion in a workplace setting, a good work environment is essential. Published by the BMJ Publishing Group Limited.

How do people evaluate social sexual conduct at work? A psycholegal model.

Science.gov (United States)

Wiener, R L; Hurt, L E

2000-02-01

The authors tested a psycholegal model of how people evaluate social sexual conduct at work with videotaped reenactments of interviews with alleged complainants, perpetrators, and other workers. Participants (200 full-time male and female workers) were randomly assigned to evaluate the complaints with either the reasonable person or reasonable woman legal standard. Participants answered questions about sexual harassment law and completed the Ambivalent Sexism Inventory. Participants who took the reasonable woman perspective, as compared with those who took the reasonable person perspective, were more likely to find the conduct harassing; this was especially the case among participants high in hostile sexism. Medium-sized gender effects were found in the severe case but were absent in the weaker, more ambiguous case. The implications of these findings for hostile work environment law are discussed.

Transgender women are disproportionately impacted by HIV. Transgender women involved in sex work may experience exacerbated violence, social exclusion, and HIV vulnerabilities, in comparison with non-sex work-involved transgender women. Scant research has investigated sex work among transgender women in the Caribbean, including Jamaica, where transgender women report pervasive violence. The study objective was to examine factors associated with sex work involvement among transgender women in Jamaica. In 2015, we implemented a cross-sectional survey using modified peer-driven recruitment with transgender women in Kingston and Ocho Rios, Jamaica, in collaboration with a local community-based AIDS service organization. We conducted multivariable logistic regression analyses to identify factors associated with paid sex and transactional sex. Exchanging oral, anal or vaginal sex for money only was categorized as paid sex. Exchanging sex for survival needs (food, accommodation, transportation), drugs or alcohol, or for money along with survival needs and/or drugs/alcohol, was categorized as transactional sex. Among 137 transgender women (mean age: 24.0 [SD: 4.5]), two-thirds reported living in the Kingston area. Overall, 25.2% reported being HIV-positive. Approximately half (n = 71; 51.82%) reported any sex work involvement, this included sex in exchange for: money (n = 64; 47.06%); survival needs (n = 27; 19.85%); and drugs/alcohol (n = 6; 4.41%). In multivariable analyses, paid sex and transactional sex were both associated with: intrapersonal (depression), interpersonal (lower social support, forced sex, childhood sexual abuse, intimate partner violence, multiple partners/polyamory), and structural (transgender stigma, unemployment) factors. Participants reporting transactional sex also reported increased odds of incarceration perceived to be due to transgender identity, forced sex, homelessness, and lower resilience, in comparison with participants reporting

Is thyroid hormones (TH) evaluation of clinical value in the work-up of males of infertile couples? Our results suggest that TH evaluation is not mandatory in the work-up of male infertility. A few previous studies performed on a limited series of subjects reported a negative impact of hyper- and hypo-thyroidism on semen volume, sperm concentration, progressive motility and normal morphology. No previous study has systematically evaluated associations between TH variation, semen parameters and ultrasound characteristics of the male genital tract. Cross-sectional analysis of a consecutive series of 172 subjects seeking medical care for couple infertility from September 2010 to November 2014. Of the entire cohort, 163 men (age 38.9 ± 8.0 years) free of genetic abnormalities were studied. All subjects underwent a complete andrological and physical examination, biochemical and hormonal assessment, scrotal and transrectal colour-Doppler ultrasound (CDUS) and semen analysis (including seminal interleukin 8 levels, sIL-8) evaluation within the same day. Among the patients studied, 145 (88.9%) showed euthyroidism, 6 (3.7%) subclinical hyper- and 12 (7.4%) subclinical hypo-thyroidism. No subjects showed overt hyper- or hypo-thyroidism. At univariate analysis, no associations among thyroid-stimulating hormone (TSH) or TH levels and sperm parameters were observed. Conversely, we observed positive associations among free triiodothyronine (fT3) and free thyroxine (fT4) levels, ejaculate volume and seminal fructose levels. In a multivariate model, after adjusting for confounders such as age, body mass index, smoking habit, sexual abstinence, calculated free testosterone, prolactin and sIL-8 levels, only the associations found for fT3 levels were confirmed. When CDUS features were investigated, using the same multivariate model, we found positive associations between fT3 levels and seminal vesicles (SV) volume, both before and after ejaculation (adj. r = 0.354 and adj. r = 0
Sampling pig farms at the abattoir in a cross-sectional study - Evaluation of a sampling method.

A cross-sectional study design is relatively inexpensive, fast and easy to conduct when compared to other study designs. Careful planning is essential to obtaining a representative sample of the population, and the recommended approach is to use simple random sampling from an exhaustive list of units in the target population. This approach is rarely feasible in practice, and other sampling procedures must often be adopted. For example, when slaughter pigs are the target population, sampling the pigs on the slaughter line may be an alternative to on-site sampling at a list of farms. However, it is difficult to sample a large number of farms from an exact predefined list, due to the logistics and workflow of an abattoir. Therefore, it is necessary to have a systematic sampling procedure and to evaluate the obtained sample with respect to the study objective. We propose a method for 1) planning, 2) conducting, and 3) evaluating the representativeness and reproducibility of a cross-sectional study when simple random sampling is not possible. We used an example of a cross-sectional study with the aim of quantifying the association of antimicrobial resistance and antimicrobial consumption in Danish slaughter pigs. It was not possible to visit farms within the designated timeframe. Therefore, it was decided to use convenience sampling at the abattoir. Our approach was carried out in three steps: 1) planning: using data from meat inspection to plan at which abattoirs and how many farms to sample; 2) conducting: sampling was carried out at five abattoirs; 3) evaluation: representativeness was evaluated by comparing sampled and non-sampled farms, and the reproducibility of the study was assessed through simulated sampling based on meat inspection data from the period where the actual data collection was carried out. In the cross-sectional study samples were taken from 681 Danish pig farms, during five weeks from February to March 2015. The evaluation showed that the sampling

Full Text Available In the first stage of this work, we perform detailed calculations for the cross sections of the electron capture on nuclei under laboratory conditions. Towards this aim we exploit the advantages of a refined version of the proton-neutron quasiparticle random-phase approximation (pn-QRPA and carry out state-by-state evaluations of the rates of exclusive processes that lead to any of the accessible transitions within the chosen model space. In the second stage of our present study, we translate the abovementioned e--capture cross sections to the stellar environment ones by inserting the temperature dependence through a Maxwell-Boltzmann distribution describing the stellar electron gas. As a concrete nuclear target we use the 66Zn isotope, which belongs to the iron group nuclei and plays prominent role in stellar nucleosynthesis at core collapse supernovae environment.

Work related musculoskeletal disorders (MSDs), poor body postures, and low back injuries are the most common problems occurring in many industries including small-medium industries. This study presents assessment and evaluation of ergonomic postures of material handling worker. That evaluation was carried out using REBA (Rapid Entire Body Assessment). REBA is a technique to quantize the fatigue experienced by the worker while manually lifting loads. Fatigue due to abnormal work posture leads to complaints of labor-perceived pain. REBA methods were used to an assessment of working postures for the existing process by a procedural analysis of body postures involved. This study shows that parts of the body have a high risk of work are the back, neck, and upper arms with REBA score 9, so action should be taken as soon as possible. Controlling actions were implemented to those process with high risk then substantial risk reduction was achieved.

Full Text Available The employment of built-up timber beams, made of commercial dimensions pieces, is becoming increasingly important in timber structures in Brazil, mainly due to the ever-growing scarcity of timber elements in larger sizes. The built-up system has vast application, from beams for residential buildings to girders for small bridges. The objective of this work is the theoretical and experimental study of nailed timber beams with composed cross section I. The design procedure of EUROCODE 5/93 and NBR 7190/97 are shown and evaluated, as well as the theory about the subject matter. The experimental evaluation of the theoretical models was made by means of bending tests in prototypes of built-up timber beams. The obtained results shows that the EUROCODE 5/93 procedure is the most indicated for evaluating effective bending stiffness, normal and shear stresses as well as the load on fasteners.

Work stress is a major problem for nurses and it can negatively influence job performance. Therefore, it is critical to explore variables that can reduce or buffer the negative effects of work stress. This study explores the moderating effects of coping strategies on the relationship between work stress and job performance for nurses in China. A cross-sectional survey of 852 nurses from four tertiary hospitals in Heilongjiang Province, China, was conducted in 2013. Descriptive statistics were reported for socioeconomic status and demographic characteristics, level of work stress, coping strategies, and job performance. Regression analysis was conducted to test the interaction between work stress and coping strategies on job performance. Three subscales of work stress were negatively related to job performance. Positive coping strategies moderated Patient Care and job performance while negative coping strategies moderated Workload and Time and performance, and between Working Environment and Resources and performance. Positive coping strategies reduce or buffer the negative effects of work stress on job performance and negative coping strategies increased the negative effects.

2010-09-01

We conducted a cross-sectional study of 802 Lebanese mothers to evaluate effect of rapid return to work on their health and that of their child. Breastfeeding practices were also assessed. The duration of maternity leave was insufficient for 72.8% of the women. Rapid return to work could cause physical and psychological problems depending on the type of work. The average length of breastfeeding was 4.7 months and while the average desired length was 10.9 months. Breastfeeding depended on the duration of the maternity leave, the possibility of breaks for breastfeeding and the presence of nurseries at work. Urgent interventions are necessary to prolong maternity leave and promote breastfeeding among working women.

The method based on the method of reduction is proposed for the evaluation of photonuclear reaction cross sections have been obtained at significant systematic uncertainties (different apparatus functions, calibration and normalization uncertainties). The evaluation method consists of using the real apparatus function (photon spectrum) of each individual experiment to reduce the data to a representation generated by an apparatus function of better quality. The task is to find the most reasonably achievable monoenergetic representation (MRAMR) of the information about cross section contained in different experiment observables and to take into account the experimental uncertainties of calibration and normalization procedures. The method was used to obtain the evaluated total photoneutron (γ, xn) reaction cross sections for 16 O, 28 Si, nat Cu, 141 Pr, and 208 Pb are presented. 79 refs., 19 figs., 6 tabs

Highlights: • An evaluation on the scenarios of work trajectory. • An evaluation using the virtual decommissioning environments. • An evaluation on work movement under radiation environments. - Abstract: This study is intended to suggest an ergonomic evaluation on the working postural comfort. This study issued for the first time a methodology in view of combination between visual field and comfort. Especially, the ergonomic evaluation using the virtual decommissioning environments is user-friendly because setup of physical mock-up environments is difficult. This study verified the front and standing postures are best working postures during movement under radiation environments of nuclear facilities. It is expected that this methodology will make it possible to establish the ergonomic plan for decommissioning of nuclear facilities and safety of decommissioning will be improved and also decommissioning costs also can be reduced.

1975-01-01

A method was presented to calculate the (n,xn) and (n,xnf) cross sections for the heavy nuclei having mass numbers of 232 1) without fission, according to the law of conventional statistical models, in the (n,xn) process. Fission can also compete with the emission of neutrons and γ-ray for the nuclei and the excitation energy considered. The fission cross sections of 235 U and 238 U recently evaluated by Sowerby and the fission cross section of 236 U have been used to determine the other parameters needed in the calculation. The fission widths of 239 U and 238 U have been obtained by fitting the first-chance and second-chance fission plateaus of the 238 U cross section. For the fission width of 238 U, good agreement was observed between the authors' results and Landrum and others' experimental data. (Iwase, T.)

Musculoskeletal disorders constitute a major problem in the wood and furniture industry and identification of risk factors is needed urgently. Therefore, exposures to different work tasks and variation in the job were recorded based on an observation survey in combination with an interview among 281 employees working in wood working and painting departments. A questionnaire survey confirmed high frequencies of symptoms from the musculoskeletal system: The one-year prevalence of symptoms from the low back was 42% and symptoms from the neck/shoulder was 40%. The exposure was evaluated based on: (1) classification of work tasks, (2) work cycle time, (3) manual materials handling, (4) working postures, and (5) variation in the job. Among the employees 47% performed feeding or clearing of machines, 35% performed wood working or painting materials, and 18% performed various other operations. Among the employees 20% had no variation in their job while 44% had little variation. Manual materials handling of 375 different burdens was observed, which most often occurred during feeding or clearing of machines. The weight of burdens lifted was 0.5-87.0 kg, where 2% had a weight of more than 50 kg. Among the lifting conditions 30% were evaluated as implying a risk of injury. An additional risk factor was the high total tonnage lifted per day, which was estimated to range from 132 kg to 58,800 kg. Working postures implied a risk of injury due to prolonged forward and lateral flexions of the neck, which was seen most frequently during wood working or painting materials. These data substantiate the finding that work tasks mainly during feeding or clearing of machines imply a risk of injury to the low back and a risk of injury to the neck and shoulder area mainly during wood working or painting materials. Optimal strategies for job redesign may be worked out by using these data in order to prevent occupational musculoskeletal disorders.

Job satisfaction largely determines the productivity and efficiency of human resource for health. It literally depicts the extent to which professionals like or dislike their jobs. Job satisfaction is said to be linked with the employee's work environment, job responsibilities and powers and time pressure; the determinants which affect employee's organizational commitment and consequently the quality of services. The objective of the study was to determine the level of and factors influencing job satisfaction among public health professionals in the public sector. This was a cross sectional study conducted in Islamabad, Pakistan. Sample size was universal including 73 public health professionals, with postgraduate qualifications and working in government departments of Islamabad. A validated structured questionnaire was used to collect data from April to October 2011. Overall satisfaction rate was 41% only, while 45% were somewhat satisfied and 14% of professionals highly dissatisfied with their jobs. For those who were not satisfied, working environment, job description and time pressure were the major causes. Other factors influencing the level of satisfaction were low salaries, lack of training opportunities, improper supervision and inadequate financial rewards. Our study documented a relatively low level of overall satisfaction among workers in public sector health care organizations. Considering the factors responsible for this state of affairs, urgent and concrete strategies must be developed to address the concerns of public health professionals as they represent a highly sensitive domain of health system of Pakistan. Improving the overall work environment, review of job descriptions and better remuneration might bring about a positive change.

The aim of this study was to investigate any possible relationship between sleep disorders, burnout and job performance in a shift-work population of nurses. Sleep disorders and burnout can affect the job performance of nurses in terms of efficiency, productivity, task execution speed and supervision, which can be compromised when work shifts are organized on a 24-hour schedule and when the shift itself is irregular. A cross-sectional observational study was conducted from August 2014 - January 2015 on a sample of 315 shift-work nurses across 39 wards in seven central Italian hospitals. The Pittsburgh Sleep Quality Index was used to detect the presence of sleep disorders, the Copenhagen Burnout Inventory was used to detect the presence of any possible type of burnout and the Job Performance Scale was used to measure job performance. Data analysis was mainly based on a multivariate logistic regression to identify variables significantly associated with investigated outcomes. On shift-work nurses' sleep quality and burnout correlated positively. The female gender and personal burnout were significantly associated with impaired sleep quality, while working in the psychiatric setting, working a long cycle shift pattern and experiencing daytime dysfunction were significantly associated with burnout. A significant negative association between patient-related burnout and job performance was observed. Specific characteristics of shift-work nurses can directly affect sleep quality and burnout and indirectly job performance. This evidence offers healthcare administrators opportunities to intervene with measures to promote nurse's health, well-being and safety. © 2017 John Wiley & Sons Ltd.

Some of the main objectives with the Aespoe Hard Rock Laboratory is reviewing and verifying the suitability of different investigations methods regarding bedrock characterization, test methods for detailed site investigations and to evaluate factors of importance for safety in realistic conditions. The SKB evaluation will result in a strategy planned to be used in the forthcoming site selection of a repository for high level radioactive waste. This report presents an evaluation of the methods used by SKB in the prediction of the bedrock prior to excavation. The prediction was based on the pre investigations carried out during 1986-1990. The review has followed the SKB classification of issue areas: geological/structural model, groundwater flow, groundwater chemistry, transport of solutes and mechanical stability. The review concerns SKB's objectives with the prediction and the different criteria for selection of variables - considering the demands of the performance assessment. This report includes evaluation of two tunnel sections, 0/700 - 1/475 and 1/475 - 2/265, comprising used data, prediction methods and prediction accuracy. By way of comparing predictions before excavation and outcome in the tunnel, a strict validation was performed. Based on the results from the validation, the applicability of different methods was estimated and the predictability of different subjects was assessed. It should be emphasised that the Aespoe predictions have not been directly intended for performance assessment purposes. However, it is of interest to see how the predictions relate to the information needs of performance assessment. By this it is possible to identify areas where more work needs to be done in the future, either in the operational phases at Aespoe or in other parts of the SKB program, thereby setting the predictions in an overall perspective from the point of view of performance assessment

The Spills Working Group was one of six working groups established under the Accident Phenomenology and Consequence (APAC) methodology evaluation program. The objectives of APAC were to assess methodologies available in the accident phenomenology and consequence analysis area and to evaluate their adequacy for use in preparing DOE facility safety basis documentation, such as Basis for Interim Operation (BIO), Justification for Continued Operation (JCO), Hazard Analysis Documents, and Safety Analysis Reports (SARs). Additional objectives of APAC were to identify development needs and to define standard practices to be followed in the analyses supporting facility safety basis documentation. The Spills Working Group focused on methodologies for estimating four types of spill source terms: liquid chemical spills and evaporation, pressurized liquid/gas releases, solid spills and resuspension/sublimation, and resuspension of particulate matter from liquid spills.

2011-01-01

This work presents a theoretical re-evaluation of a set of original experiments included in the 2009 issue of the International Handbook of Evaluated Criticality Safety Benchmark Experiments, as “Concrete Reflected Cylinders of Highly Enriched Solutions of Uranyl Nitrate” (identification number: HEU-SOL-THERM- 002) [4]. The present evaluation has been made according to benchmark specifications [4], and added data taken out of the original published report [3], but applying a different approach, resulting in a more realistic calculation model. In addition, calculations have been made using the latest version of MCNPX Monte Carlo code, combined with an updated set of cross section data, the continuous-energy ENDF/B-VI library. This has resulted in a comprehensive model for the given experimental situation. Uncertainties analysis has been made based on the evaluation of experimental data presented in the HEU-SOLTHERM-002 report. Resulting calculations with the present improved physical model have been able to reproduce the criticality of configurations within 0.5%, in good agreement with experimental data. Results obtained in the analysis of uncertainties are in general agreement with those at HEU-SOL-THERM-002 benchmark document. Qualitative results from analyses made in the present work can be extended to similar fissile systems: well moderated units of 235 U solutions, reflected with concrete from all directions. Results have confirmed that neutron absorbers, even as impurities, must be taken into account in calculations if at least approximate proportions were known. (authors)

A better knowledge of the job aspects that may predict home health care nurses' burnout and work engagement is important in view of stress prevention and health promotion. The Job Demands-Resources model predicts that job demands and resources relate to burnout and work engagement but has not previously been tested in the specific context of home health care nursing. The present study offers a comprehensive test of the Job-Demands Resources model in home health care nursing. We investigate the main and interaction effects of distinctive job demands (workload, emotional demands and aggression) and resources (autonomy, social support and learning opportunities) on burnout and work engagement. Analyses were conducted using cross-sectional data from 675 Belgian home health care nurses, who participated in a voluntary and anonymous survey. The results show that workload and emotional demands were positively associated with burnout, whereas aggression was unrelated to burnout. All job resources were associated with higher levels of work engagement and lower levels of burnout. In addition, social support buffered the positive relationship between workload and burnout. Home health care organizations should invest in dealing with workload and emotional demands and stimulating the job resources under study to reduce the risk of burnout and increase their nurses' work engagement.

Health personnel are key players in developing and improving healthcare systems, caring for individuals and their communities, and helping improve quality of life. However, these professionals are often exposed to long working hours because of the pressing need for their services at potentially any time of day. The long working hours they endure are a major risk factor for both acute and chronic health problems. The present study aimed to analyze occurrences of long working hours and their association with individual characteristics and employment factors among workers in the municipal healthcare system in Belo Horizonte, Brazil. In this cross-sectional study, a ramdomly selected proportional sample of 1549 participants was analyzed from among the total of 13 602 workers in the Belo Horizonte municipal healthcare system in 2009. "Long" working hours were defined as >44 h/week. A self-administered questionnaire was used for accumulating data. Associations with outcomes were estimated using logistic regression, in univariate and multivariate models. The rate of occurrence of long working hours was 31.4% (95% CI 29.1-33.7). Lower educational level (high school, technical, or uncompleted undergraduate [OR 0.60, 95% CI 0.47-0.78 p long working hours in relation to the group with the highest educational level (completed undergraduate or postgraduate). Male sex (OR 1.62, 95% CI 1.26-2.09 p long working hours. It was observed that number of long weekly working hours was related to individual characteristics and employment factors.
The challenges of joint working: lessons from the Supporting People Health Pilot evaluation

Full Text Available Purpose: This paper reports the findings of the evaluation of the Supporting People Health Pilots programme which was established to demonstrate the policy links between housing support services and health and social care services by encouraging the development of integrated services. The paper highlights the challenges of working across housing, health and social care boundaries. Method: The evaluation of the 6 health pilots rested on two main sources of data collection: Quarterly Project Evaluation Reports collected process data as well as reporting progress against aims and objectives. Semi-structured interviews - conducted across all key professional stakeholder groups and agencies and with people who used services - explored their experiences of these new services. Results: The ability of pilots to work across organisational boundaries to achieve their aims and objectives was associated not only with agencies sharing an understanding of the purpose of the joint venture, a history of joint working and clear and efficient governance arrangements but on two other characteristics: the extent and nature of statutory sector participation and, whether or not the service is defined by a history of voluntary sector involvement. In particular the pilots demonstrated how voluntary sector agencies appeared to be less constrained by organisational priorities and professional agenda and more able to respond flexibly to meet the complex needs of individuals. Conclusion and discussion: The pilots demonstrate that integrating services to support people with complex needs works best when the service is determined by the characteristics of those who use the service rather than pre-existing organisational structures.

In the present work the authors have verified the influence of the position of slotted section casing on heat rate drawn by plants for exploitation of geothermal reservoirs that use heat exchangers placed at the bottom of the well (DHE). This study have been done modelling numerically the aquifer, by means of finite element method, evaluating the heat rate drawn by the heat exchanger at different position of the slotted section of the tube casing. Numerical calculations have allowed to show the influence of the main characteristics of the aquifer and of the main characteristics of the aquifer and of the plant on design of the slotted section of the tube casing. In particular, the authors have studied the influence of i) equivalent conductivity and permeability of the aquifer, ii) mass flow rate and the inlet and outlet aquifer temperature difference in the well, iii) the ratio between the length of the slotted section and the thickness of the geothermal layer, varying the position of the slotted section of the tube casing in the aquifer [it

Background Like other health professionals, community pharmacists are exposed to stress factors (being efficient, avoiding mistakes and bearing emotional load), but they are also under the pressure of entrepreneurial responsibilities. The main objective was to assess the level of work-related stress in French community pharmacies. The other objectives of the study were to assess the associated comorbidities and causes of work-related stress. Methods This observational cross-sectional study was sent to all French community pharmacies by email. The survey was anonymous and designed to collect the following items: socio-demographic factors, professional status, characteristics of community pharmacy, work-related stress (visual analogic scale—VAS), fatigue (VAS), sleep disturbances (questions), anxiety and depression symptoms (hospital anxiety and depression scale), medical consultation for work-related stress, medication use for work related stress, psychoactive drug-use and causes of work-related stress. Participants were included in the survey if they were pharmacists (owner or assistant) or pharmacy technicians working in a community pharmacy at the time of the survey. Exclusion criteria were defined as follows: pharmacy students or other professionals involved in a community pharmacy (e.g. dietician, beautician) and lack of professional status information. There was no age limitation. Results After three months of data collection, 1,339 participants answered the survey and 1,272 participants were included in conformity with the inclusion and exclusion criteria, and to avoid missing data on the primary endpoint. Work-related stress was detected in 32.8% (417/1,272) of individuals (scores ≥70/100). Men were significantly more affected than women and there was no difference between professional statuses and no relation with the age of the participants.

Halila, Ritva

2014-12-01

The main task of research ethics committees (RECs) is to assess research studies before their start. In this study, 24 RECs that evaluate medical research were sent questionnaires about their structure and functions. The RECs were divided into two separate groups: those working in university hospital districts (uRECs) and those in central hospital districts (non-uRECs). The two groups were different in many respects: the uRECs were bigger in size, covered a wider range of disciplines (both medical and non-medical), had better resources and more frequent and regular meetings. After the survey was performed and analysed, the Medical Research Act was amended so that only hospital districts with a medical faculty in their region had a duty to establish ethics committees. After the amendment, the number of RECs evaluating medical research in Finland decreased from 25 to 9. The ethics committees that remained had wider expertise and were better equipped already by the time of this survey. Only one non-uREC was continuing its work, and this was being done under the governance of a university hospital district. Simple measures were used for qualitative analysis of the work of RECs that evaluate medical research. These showed differences between RECs. This may be helpful in establishing an ethics committee network in a research field or administrational area. Published by the BMJ Publishing Group Limited.

This study evaluated the diagnostic accuracy of the Work Functioning Impairment Scale (WFun), a questionnaire to detect workers with health problems which affect their work, using an assessment by an occupational health nurse as objective standard. The WFun was completed by 294 employees. The nurse interviewed to assess 1) health problems; 2) effects of health on their work; necessity for 3) treatment, 4) health care instruction, and 5) consideration of job accommodation. The odds ratio in the high work functioning impairment group compared with the low was highly statistically significant with 9.05, 10.26, 5.77, 9.37, and 14.70, respectively. The WFun demonstrated the high detectability with an area under the receiver operating characteristic of 0.75, 0.81, 0.72, 0.79, and 0.83, respectively. This study suggests that the WFun is useful in detecting those who have health problems affecting their work.

Nurses' turnover is a major contributor to nursing shortages, strongly influenced by nurses' intentions to leave. Several factors influencing the turnover intention have been well identified in Western countries and large cities in China. However, whether these factors also contribute to nurses' work stress in Midwest China are still unclear. The main purpose of this study was to examine the work pressure and associated factors influencing the nurses' intent to leave. A cross-sectional questionnaire-based survey with multistage sampling was conducted by recruiting 800 employed registered nurses with >1 year of work experience. Chi-square test and multi-factor logistic regression were applied to attain the relative comparisons. Sub-group analysis was conducted to explore the different turnover intention patterns in different age groups. The turnover intention was classified as strong/very-strong (19%), weak (62%), and very-weak (19%). Among the factors influencing the nurses' desire to leave the profession, work pressure was the most prominent. The predominantly associated factors contributing the work stress were age, experience, and workload. However, the scale of income did not affect the intent to leave decision. Pediatrics was identified to be the highest tormented department with a significant (P stress, age, job duty, and career commitment in Shaanxi Province. The intent to leave is dynamically multifactorial, and effective managements and supportive strategies are needed to reduce the nurses work stress accordingly.

A newly developed computational procedure is presented for the generation of d-Li source neutrons in Monte Carlo transport calculations based on the use of evaluated double-differential d+ 6,7 Li cross section data. A new code M c DeLicious was developed as an extension to MCNP4C to enable neutronics design calculations for the d-Li based IFMIF neutron source making use of the evaluated deuteron data files. The M c DeLicious code was checked against available experimental data and calculation results of M c DeLi and MCNPX, both of which use built-in analytical models for the Li(d, xn) reaction. It is shown that M c DeLicious along with newly evaluated d+ 6,7 Li data is superior in predicting the characteristics of the d-Li neutron source. As this approach makes use of tabulated Li(d, xn) cross sections, the accuracy of the IFMIF d-Li neutron source term can be steadily improved with more advanced and validated data

The Coupled Fast Reactivity Measurements Facility (CFRMF) at the Idaho National Engineering Laboratory (INEL) is a Cross Section Evaluation Working Group (CSEWG) benchmark for data testing of dosimetry, fission-product and actinide cross sections important to fast-reactor technology. In this paper we present the results of our work in updating the CFRMF spectrum characterization and in applying CFRMF integral data to testing ENDF/B-V dosimeter cross sections. Updated characterization of the central neutron spectrum includes the results of neutronics calculations with ENDF/B-V nuclear data, the generation of a fine-group spectrum representation for integral data-testing applications, and a sensitivity and uncertainty analysis which provides a flux-spectrum covariance matrix related to uncertainties and correlations in the nuclear data used in a neutronics calculation. Our application of CFRMF integral data to cross section testing has included both conventional integral testing analyses and least-squares-adjustment analyses with the FERRET code. The conventional integral data-testing analysis, based on C/E ratios, indicates discrepancies outside the estimated integral test uncertainty for the 6 Li(n,He), 10 B(n,He), 47 Ti(n,p), 58 Fe(n,γ), 197 Au(n,γ) and 232 Th(n,γ) cross sections. The integral test uncertainty included contributions from the measured integral data and from the spectrum and cross sections used to obtain the calculated integral data. Within the uncertainty and correlation specifications for the input spectrum and dosimeter cross sections, the least-squares-adjustment analysis indicated a high degree of consistency between the measured integral data and the ENDF/B-V dosimeter cross sections for all reactions except 10 B

Full Text Available Abstract Background Job satisfaction largely determines the productivity and efficiency of human resource for health. It literally depicts the extent to which professionals like or dislike their jobs. Job satisfaction is said to be linked with the employee’s work environment, job responsibilities and powers and time pressure; the determinants which affect employee’s organizational commitment and consequently the quality of services. The objective of the study was to determine the level of and factors influencing job satisfaction among public health professionals in the public sector. Methods This was a cross sectional study conducted in Islamabad, Pakistan. Sample size was universal including 73 public health professionals, with postgraduate qualifications and working in government departments of Islamabad. A validated structured questionnaire was used to collect data from April to October 2011. Results Overall satisfaction rate was 41% only, while 45% were somewhat satisfied and 14% of professionals highly dissatisfied with their jobs. For those who were not satisfied, working environment, job description and time pressure were the major causes. Other factors influencing the level of satisfaction were low salaries, lack of training opportunities, improper supervision and inadequate financial rewards. Conclusion Our study documented a relatively low level of overall satisfaction among workers in public sector health care organizations. Considering the factors responsible for this state of affairs, urgent and concrete strategies must be developed to address the concerns of public health professionals as they represent a highly sensitive domain of health system of Pakistan. Improving the overall work environment, review of job descriptions and better remuneration might bring about a positive change.
Changes in the classification of carcinogenic chemicals in the work area. (Section III of the German List of MAK and BAT values).

Carcinogenic chemicals in the work area were previously classified into three categories in section III of the German List of MAK and BAT values (the list of values on maximum workplace concentrations and biological tolerance for occupational exposures). This classification was based on qualitative criteria and reflected essentially the weight of evidence available for judging the carcinogenic potential of the chemicals. In the new classification scheme the former sections IIIA1, IIIA2, and IIIB are retained as categories 1, 2, and 3, to correspond with European Union regulations. On the basis of our advancing knowledge of reaction mechanisms and the potency of carcinogens, these three categories are supplemented with two additional categories. The essential feature of substances classified in the new categories is that exposure to these chemicals does not contribute significantly to the risk of cancer to man, provided that an appropriate exposure limit (MAK value) is observed. Chemicals known to act typically by non-genotoxic mechanisms, and for which information is available that allows evaluation of the effects of low-dose exposures, are classified in category 4. Genotoxic chemicals for which low carcinogenic potency can be expected on the basis of dose/response relationships and toxicokinetics and for which risk at low doses can be assessed are classified in category 5. The basis for a better differentiation of carcinogens is discussed, the new categories are defined, and possible criteria for classification are described. Examples for category 4 (1,4-dioxane) and category 5 (styrene) are presented.
On making laboratory report work more meaningful through criterion-based evaluation.

Naeraa, N

1987-05-01

The purpose of this work was to encourage students to base their laboratory report work on guidelines reflecting a quality criterion set, previously derived from the functional role of the various sections in scientific papers. The materials were developed by a trial-and-error approach and comprise learning objectives, a parallel structure of manual and reports, general and specific report guidelines and a new common starting experiment. The principal contents are presented, followed by an account of the author's experience with them. Most of the author's students now follow the guidelines. Their conclusions are affected by difficulties in adjusting expected results with due regard to the specific conditions of the experimental subject or to their own deviations from the experimental or analytical procedures prescribed in the manual. Also, problems in interpreting data unbiased by explicit expectations are evident, although a clear distinction between expected and actual results has been helpful for them in seeing the relationship between experiments and textbook contents more clearly, and thus in understanding the hypothetico-deductive approach.

Full Text Available In previous works we presented the studies that discussed how students evaluate their teachers and their style of teaching. To what extent their styles affect the students’ attitudes to teaching, learning, success, motivation and the like. In this work we have tried to point out how teachers assess their style of work, depending on the subject they teach and years of work experience. In addition, the aim of this study was to examine whether there are differences in teachers’ estimation of the teaching styles depending on the subject they teach and years of work experience. The study sample consisted of 120 teachers in the final grades of primary schools in the Sarajevo – Romania region. Teachers responded to questions assessing which of the statements given are related to them. The questionnaire was designed for research purposes with the three styles that are commonly used in the classroom to a democratic, autocratic and laissez - fair style. Reliability of the instrument was tested using Cronbach - alpha coefficient, and amounted to 0.73 democratic style, the autocratic 0.73, and 0.63 for the indifferent style. In the study, we used two methods: survey method and the method of theoretical analysis. The obtained results show that there is a statistically significant difference in teachers’ assessments of democratic and laissez - fair style usage, depending on the subject they teach, while there was no statistically significant difference when it comes to the autocratic style. The second part of our results shows that there is no difference in teachers’ assessments of work styles, depending on years of work experience. We hope that these results will contribute to the already existing research dealing with this subject.

Full Text Available Working memory is a cognitive process that is particularly vulnerable to decline with age. The current study sought to evaluate the efficacy of a working memory training scheme in improving memory in a group of older adults. A 5-week online training scheme was designed to provide training in the main components of Baddeley’s (2000 working memory model, namely auditory and visuospatial short-term and working memory. A group of older adults aged between 64 and 79 were randomly assigned to a trainee (n = 19 or control (n = 17 group, with trainees engaging in the adaptive training scheme and controls engaging in a non-adaptive version of the programme. Before and after training and at 3- and 6-month follow-up sessions, trainees and controls were asked to complete measures of short-term and working memory, long-term episodic memory, subjective ratings of memory and attention and achievement of goals set at the beginning of training. The results provided evidence of an expansion of auditory short-term memory span, which was maintained 6 months later, and transfer to long-term episodic memory but no evidence of improvement in working memory capacity per se. A serendipitous and intriguing finding of a relationship between time spent training, psychological stress and training gains provided further insight into individual differences in training gains in older adults.
Comparative evaluation of photon cross section libraries for materials of interest in PET Monte Carlo simulations

CERN Document Server

Zaidi, H

1999-01-01

the many applications of Monte Carlo modelling in nuclear medicine imaging make it desirable to increase the accuracy and computational speed of Monte Carlo codes. The accuracy of Monte Carlo simulations strongly depends on the accuracy in the probability functions and thus on the cross section libraries used for photon transport calculations. A comparison between different photon cross section libraries and parametrizations implemented in Monte Carlo simulation packages developed for positron emission tomography and the most recent Evaluated Photon Data Library (EPDL97) developed by the Lawrence Livermore National Laboratory was performed for several human tissues and common detector materials for energies from 1 keV to 1 MeV. Different photon cross section libraries and parametrizations show quite large variations as compared to the EPDL97 coefficients. This latter library is more accurate and was carefully designed in the form of look-up tables providing efficient data storage, access, and management. Toge...

Implementation of primary care has long been a priority in low- and middle-income countries. Violence at work may hamper progress in this field. Hence, we examined the associations between violence at work and depressive symptoms/major depression in primary care teams (physicians, nurses, nursing assistants, and community health workers). A cross-sectional study was undertaken in the city of Sao Paulo, Brazil. We assessed a random sample of Family Health Program teams. We investigated depressive symptoms and major depression using the nine-item Patient Health Questionnaire (PHQ-9), and exposure to violence at work in the previous 12 months using a standardized questionnaire. Associations between exposure to violence and depressive symptoms/major depression were analyzed using multinomial logistic regression. Of 3141 eligible workers, 2940 (93 %) completed the interview. Of these, 36.3 % (95 % CI 34.6-38.1) presented intermediate depressive symptoms, and 16 % (95 % CI 14.6-17.2), probable major depression. The frequencies of exposure to the different types of violence at work were: insults (44.9 %), threats (24.8 %), physical aggression (2.3 %), and witnessing violence (29.5 %). These exposures were strongly and progressively associated with depressive symptoms (adjusted odds ratio 1.67 for exposure to one type of violence; and 5.10 for all four types), and probable major depression (adjusted odds ratio 1.84 for one type; and 14.34 for all four types). Primary care workers presenting depressive symptoms and those who have experienced violence at work should be assisted. Policy makers should prioritize strategies to prevent these problems, since they can threaten primary care sustainability.

Objective: To evaluate the imaging signs of aging lung in asymptomatic adult subjects by using thin-section spiral CT, and analyze the correlation between the signs and the age of examined cases, as well as probe their clinical application value. Methods: One hundred and six healthy adult subjects were divided into 3 groups: 30 to 44 years (n=31), 45 to 59 years (n=30), and over 60 years (n=45), and all the subjects underwent thin-section spiral CT scans in the upper lung field, the middle lung field and the lower lung field. The evaluation indices included the lung interstitium changes, emphysematous changes, mosaic perfusion, dependent density difference, and pleural thickenning. According to the relative score standard, the above-mentioned indices were totally calculated and converted into the score value. The data were statistically processed with SPSS for Windows. Results: Among the three groups, there were remarkable differences in the indices including the lung interstitium changes, emphysematous changes, and mosaic perfusion, respectively (χ 2 =8.10, 9.73, 15.54, P 2 =3.66, 3.24, P> 0.05). The score values had a significant positive correlation with the age (r=0.709, P<0.01). Conclusion: The signs including the lung interstitium changes, emphysematous changes, mosaic perfusion, the dependent density difference, and pleural thickenning can be found in asymptomatic subjects, and they become prominent as the age increases. HRCT is one of the most important methods for evaluating the early signs of the senile lung. (authors)

Bangladesh is one of the leading exporters of ready-made garments (RMG) worldwide producing at very low cost almost exclusively for Western markets. Empirical evidence on psychologically adverse working conditions and their association with health in the RMG setting remains sparse. Drawing on insights from previous ethnographic research, we conducted a cross-sectional epidemiological study among 332 RMG workers in Dhaka, Bangladesh. High work-related demands and poor interpersonal resources represented key components of work stress and were important determinants of poor health. The key work stress components observed in this study partly differed from those identified in Western work place settings. © 2013 The Authors. Published by Elsevier Ltd. All rights reserved.
Evaluation of essential work of fracture in a dual phase high strength steel sheet

International Nuclear Information System (INIS)

Gutierrez, D.; Perez, L. I.; Lara, A.; Casellas, D.; Prado, J. M.

2013-01-01

Fracture toughness of advanced high strength steels (AHSS), can be used to optimize crash behavior of structural components. However it cannot be readily measured in metal sheet because of the sheet thickness. In this work, the Essential Work of Fracture (EWF) methodology is proposed to evaluate the fracture toughness of metal sheets. It has been successfully applied in polymers films and some metal sheets. However, their information about the applicability of this methodology to AHSS is relatively scarce. In the present work the fracture toughness of a Dual Phase (strength of 800 MPa) and drawing steel sheets has been measured by means of the EWF. The results show that the test requirements are met and also show the clear influence of notch radii on the measured values, specially for the AHSS grade. Thus, the EWF is postulated as a methodology to evaluate the fracture toughness in AHSS sheets. (Author) 18 refs.

Recent measurements of capture and total cross sections performed at the Rensselaer Polytechnic Institute in the USA confirmed many of the gadolinium thermal and resonant neutron cross section parameters within uncertainties, but they also showed up important discrepancies well out of uncertainties, such as an approx11% overestimation of the {sup 157}Gd thermal capture cross section in ENDF/B-VI and -VII with respect to the newly measured data. In this work, the impact of the newly measured gadolinium cross sections on BWR reactor physics parameters has been preliminarily evaluated. The comparisons of rod-by-rod fission rate and modified conversion ratio predictions with selected cold critical experiments at the PROTEUS reactor in Switzerland show the potential to resolve long-term unexplained discrepancies.

Background-cross-section-dependent subgroup parameters

International Nuclear Information System (INIS)

Yamamoto, Toshihisa

2003-01-01

A new set of subgroup parameters was derived that can reproduce the self-shielded cross section against a wide range of background cross sections. The subgroup parameters are expressed with a rational equation which numerator and denominator are expressed as the expansion series of background cross section, so that the background cross section dependence is exactly taken into account in the parameters. The advantage of the new subgroup parameters is that they can reproduce the self-shielded effect not only by group basis but also by subgroup basis. Then an adaptive method is also proposed which uses fitting procedure to evaluate the background-cross-section-dependence of the parameters. One of the simple fitting formula was able to reproduce the self-shielded subgroup cross section by less than 1% error from the precise evaluation. (author)

Feature Extraction for Track Section Status Classification Based on UGW Signals

Directory of Open Access Journals (Sweden)

Lei Yuan

2018-04-01

Full Text Available Track status classification is essential for the stability and safety of railway operations nowadays, when railway networks are becoming more and more complex and broad. In this situation, monitoring systems are already a key element in applications dedicated to evaluating the status of a certain track section, often determining whether it is free or occupied by a train. Different technologies have already been involved in the design of monitoring systems, including ultrasonic guided waves (UGW. This work proposes the use of the UGW signals captured by a track monitoring system to extract the features that are relevant for determining the corresponding track section status. For that purpose, three features of UGW signals have been considered: the root mean square value, the energy, and the main frequency components. Experimental results successfully validated how these features can be used to classify the track section status into free, occupied and broken. Furthermore, spatial and temporal dependencies among these features were analysed in order to show how they can improve the final classification performance. Finally, a preliminary high-level classification system based on deep learning networks has been envisaged for future works.

Most research on night and shift work focuses on employee health in large companies, primarily in the healthcare and transportation sectors. However, many night workers work on their own or in small businesses related to services or food. This survey focuses on sleep habits and disorders concerning night work in pastry production and sales. An epidemiological telephone cross-sectional survey of night shift workers and their sleep habits was proposed to all employers and employees in the French pastry industry via their insurance health prevention company. Sleep logs allow us to estimate the total sleep time (TST) on workdays and enquire on napping episodes and length. In order to estimate the ideal TST, we added a question on the ideal amount of sleep the subjects need to be in good shape in the morning. We also define sleep debt as the difference between the ideal TST and TST on workdays, and considered a sleep debt when the difference was above 60 min and severe sleep debt above 90 min. Finally we retained subjects as long sleepers for those with a TSTof more than 7 hours and short sleepers when TST was under 5 hours. Insomnia, sleepiness and sleep apnoea have been defined based on the International Classification of Sleep Disorders-Third Edition and the classification of mental disorders (Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition). Bivariate and multivariate logistic regression models were applied to investigate the association with short TST, long TST, sleep debt and napping. We analysed 2622 complete questionnaires from 1313 men and 1309 women aged 22-50 years old. 1397 workers began work before 07:00, whereas 1225 began later. The 24-hour TST was 6.7±1.4 hours, whereas the ideal TST was 7.0±1.2 hours. Severe sleep debt (>90 min) was reported by 6% women versus 5% men, whereas moderate sleep debt (>60 min) was reported by 11.5% women versus 9.3% men. Napping is one way to improve 24-hour TST for 58% of pastry

The 235 U(n,f) cross section is evaluated in the energy range from 100 keV to 20 MeV. Experimental data are included up to the 1978 Harwell Conference on Neutron Physics. The evaluation methodology is discussed in detail. The shape and the normalization of the cross section are evalutated in separate steps. An extensive comparison of the evaluation result with experimental data sets is made. The shape of the cross section obtained in a preliminary version of the present evaluation and a normalization factor extracted from data provided within the framework of this evaluation were used by the Subcommittee on Standards and Normalizations of the Cross Sections Evaluation Working Group to establish 235 U(n,f) for ENDF/B-V above 100 keV. 20 figures, 6 tables

Emotional exhaustion is an important component of burnout. Burnout is common among doctors. It affects the physical and mental health of doctors, their performance and the quality of care they provide. This study aimed to investigate the level and factors associated with emotional exhaustion among doctors in pediatric practice in Malaysia. A self-administered questionnaire was used in this multicenter cross-sectional study. It included questions on the socio-demographics, work characteristics, Emotional Exhaustion, Perceived Stress Scale and sources of job stress. Descriptive, univariate and multivariate analysis were conducted using the SPSS software. A total of 197 doctors working in the Pediatric department in eight hospitals returned complete questionnaire. High and moderate emotional exhaustion was reported by 25.4% and 24.4% doctors, respectively. In bivariate analysis, 29 out of the 38 items of sources of stress showed significant association with emotional exhaustion (p appreciation from supervisors, lack of incentives and promotions, time pressures and deadlines to meet, and setting unrealistic goals of having them imposed on oneself (p workplace but not with socio-demographic factors.

2014-01-01

Background Workers in Primary Health Care are often exposed to stressful conditions at work. This study investigated the association between adverse psychosocial work conditions and poor quality of life among Primary Health Care workers. Methods This cross-sectional study included all 797 Primary Health Care workers of a medium-sized city, Brazil: doctors, nurses, nursing technicians and nursing assistants, dentists, oral health technicians, and auxiliary oral hygienists, and community health workers. Data were collected by interviews. Quality of life was assessed using the WHOQOL-BREF; general quality of life, as well as the physical, psychological, social and environmental domains were considered, with scores from 0 to 100. Higher scores indicate a better quality of life. Poor quality of life was defined by the lowest quartiles of the WHOQOL score distributions for each of the domains. Adverse psychosocial work conditions were investigated by the Effort-Reward Imbalance model. Associations were verified using multiple logistic regression. Results Poor quality of life was observed in 117 (15.4%) workers. Workers with imbalanced effort-reward (high effort/low reward) had an increased probability of general poor quality of life (OR = 1.91; 1.07–3.42), and in the physical (OR = 1.62; 1.02–2.66), and environmental (OR = 2.39; 1.37–4.16) domains; those with low effort/low reward demonstrated a greater probability of poor quality of life in the social domain (OR = 1.82; 1.00–3.30). Workers with overcommitment at work had an increased likelihood of poor quality of life in the physical (OR = 1.55, 1.06–2.26) and environmental (OR = 1.69; 1.08–2.65) domains. These associations were independent of individual characteristics, job characteristics, lifestyle, perception of general health, or psychological and biological functions.

Returning to work after periods of sick-leave due to chronic pain problems, involve a number of situations of interpersonal nature (e.g. meeting supervisors/insurance companies to adapt work setting to present functional level, receive help from colleagues, express pain, etc.). Since chronic pain has shown co-morbidity with social anxiety, it is of interest to investigate restraining factors in return to work among chronic pain sufferers from a social perspective. Catastrophizing is identified in both pain and social anxiety as a mechanism that might fuel a continuous bias in how situations are perceived (threat) and by hindering the development of functional behavior strategies. The presence of social anxiety in chronic pain patients might be seen as a stressor that limits the individuals' ability to effectively communicate pain-related needs to colleagues, and/or employers and therefore act as a hindering factor in return-to-work. Hence, the overall aim of this study was to examine the relationship between social anxiety, pain catastrophizing, and perceived ability to communicate pain-related needs to the work environment in a clinical pain population. The study employed a cross-sectional design and involved 247 individuals with chronic pain (82.3% women; M age =44 years). Measures included the Pain catastrophizing Scale, the Social Phobia Screening Questionnaire and the communication of pain-related needs-subscale of the Return-To-Work Self-efficacy Questionnaire. Analyzes were run to examine whether social anxiety moderated the relation between pain catastrophizing, and perceived ability to communicate pain-related needs while controlling for pain severity/interference and sick leave. Social anxiety and pain catastrophizing correlated positively with each other and negatively with perceived ability to communicate pain-related needs. No support was obtained for a moderating effect of social anxiety. However, social anxiety and pain interference were each

Full Text Available Background. Job satisfaction is an important determinant of health staff’s motivation, retention, and performance. Difficulties in critical decision-making and problems with lack of respect and recognition lead to lower job satisfaction level among anesthetists. It leads to high turnover intention, dropout from the profession, burnout, impaired health status of anesthetists, and lower work performance. Objective. The aim of this multicenter cross-sectional study was to assess the level of job satisfaction and associated factors among anesthetists working in Amhara National Regional State. Methods. A multicenter cross-sectional study was conducted from April 1 to June 30, 2017. Ninety-eight anesthetists that were working in Amhara National Regional State Hospitals were involved in this study. The structured questionnaire was scored on five-point Likert scales. Data were analyzed using Statistical Package for Social Sciences version 20. Binary logistic regression was used to measure statistical significance between dependent and each independent variable. Variables with P value of ≤0.2 on crude analysis were taken into multivariate analysis, and P value 0.05 and 95% CI was used as cut off point. Result. 98 out of 104 participants were involved in this study with a response rate of 94.3%. The overall level of job satisfaction was 46.9%. Anesthetists in academic working position were satisfied with the odds of about 2.3 (AOR = 2.269; CI = 1.137–6.740 compared to those in clinical working position. Anesthetists were least satisfied with coworker relationships (37.8%, work schedule (43.9%, professional opportunity (46.9%, and recognition (49% while they were most satisfied from their control of responsibility (59.2%, social interaction (55%, and salary and benefits (51%. Conclusion and Recommendation. Job satisfaction of anesthetists was low, and we suggest that facilitation of professional development, creation of smooth relationship in

There are differences among experimental cross-sections for 16 O, which make the evaluated data still uncertain. R-matrix is rigorous and straightforward to the quantum mechanical theory. We estimate the neutron cross-sections for 16 O up to 5.2 MeV through R-matrix analysis. In this work, particular attention is paid to issues in the scale of (n,α) reaction cross-sections and hydrogen contents in some of the experimental total cross-sections. Our preliminary results suggest that those problems could be solved/reduced due to the physical constraints imposed by the theory. (authors)

A Working Party on International Evaluation Co-operation was established under the sponsorship of the OECD/NEA Nuclear Science Committee (NSC) to promote the exchange of information on nuclear data evaluations, validation, and related topics. Its aim is also to provide a framework for co-operative activities between members of the major nuclear data evaluation projects. This includes the possible exchange of scientists in order to encourage co-operation. Requirements for experimental data resulting from this activity are compiled. The Working Party determines common criteria for evaluated nuclear data files with a view to assessing and improving the quality and completeness of evaluated data. The Parties to the project are: ENDF (United States), JEFF/EFF (NEA Data Bank Member countries), and JENDL (Japan). Co-operation with evaluation projects of non-OECD countries are organised through the Nuclear Data Section of the International Atomic Energy Agency (IAEA). This report is issued by a Subgroup investigating discrepancies in different evaluations of the major structural materials. The isotopes selected are Chromium-52, Iron-56 and Nickel-58. Graphical overlay comparisons between cross-sections, and also energy-angle correlated particle distributions, in different evaluated libraries was performed. Benefits from these comparisons include information useful for improving structural material evaluations in individual data libraries, for assessing differences associated with present-day evaluation techniques and for development of techniques for graphical representation of the energy-angle correlated data

We present calculations of neutron thermal cross sections, Westcott factors, resonance integrals, Maxwellian-averaged cross sections and astrophysical reaction rates for 843 ENDF materials using data from the major evaluated nuclear libraries and European activation file. Extensive analysis of newly-evaluated neutron reaction cross sections, neutron covariances, and improvements in data processing techniques motivated us to calculate nuclear industry and neutron physics quantities, produce s-process Maxwellian-averaged cross sections and astrophysical reaction rates, systematically calculate uncertainties, and provide additional insights on currently available neutron-induced reaction data. Nuclear reaction calculations are discussed and new results are presented. Due to space limitations, the present paper contains only calculated Maxwellian-averaged cross sections and their uncertainties. The complete data sets for all results are published in the Brookhaven National Laboratory report.
