Residues that are crucial to protein function or structure are usually evolutionarily conserved. To identify the important residues in protein, sequence conservation is estimated, and current methods rely upon the unbiased collection of homologous sequences. Surprisingly, our previous studies have shown that the sequence conservation is closely correlated with the weighted contact number (WCN), a measure of packing density for residue's structural environment, calculated only based on the C α positions of a protein structure. Moreover, studies have shown that sequence conservation is correlated with environment-related structural properties calculated based on different protein substructures, such as a protein's all atoms, backbone atoms, side-chain atoms, or side-chain centroid. To know whether the C α atomic positions are adequate to show the relationship between residue environment and sequence conservation or not, here we compared C α atoms with other substructures in their contributions to the sequence conservation. Our results show that C α positions are substantially equivalent to the other substructures in calculations of various measures of residue environment. As a result, the overlapping contributions between C α atoms and the other substructures are high, yielding similar structure-conservation relationship. Take the WCN as an example, the average overlapping contribution to sequence conservation is 87% between C α and all-atom substructures. These results indicate that only C α atoms of a protein structure could reflect sequence conservation at the residue level. © 2017 Wiley Periodicals, Inc.

Cost-Effective Large-Scale Occupancy-Abundance Monitoring of Invasive Brushtail Possums (Trichosurus Vulpecula on New Zealand's Public Conservation Land.

Directory of Open Access Journals (Sweden)

Andrew M Gormley

Full Text Available There is interest in large-scale and unbiased monitoring of biodiversity status and trend, but there are few published examples of such monitoring being implemented. The New Zealand Department of Conservation is implementing a monitoring program that involves sampling selected biota at the vertices of an 8-km grid superimposed over the 8.6 million hectares of public conservation land that it manages. The introduced brushtail possum (Trichosurus Vulpecula is a major threat to some biota and is one taxon that they wish to monitor and report on. A pilot study revealed that the traditional method of monitoring possums using leg-hold traps set for two nights, termed the Trap Catch Index, was a constraint on the cost and logistical feasibility of the monitoring program. A phased implementation of the monitoring program was therefore conducted to collect data for evaluating the trade-off between possum occupancy-abundance estimates and the costs of sampling for one night rather than two nights. Reducing trapping effort from two nights to one night along four trap-lines reduced the estimated costs of monitoring by 5.8% due to savings in labour, food and allowances; it had a negligible effect on estimated national possum occupancy but resulted in slightly higher and less precise estimates of relative possum abundance. Monitoring possums for one night rather than two nights would provide an annual saving of NZ$72,400, with 271 fewer field days required for sampling. Possums occupied 60% (95% credible interval; 53-68 of sampling locations on New Zealand's public conservation land, with a mean relative abundance (Trap Catch Index of 2.7% (2.0-3.5. Possum occupancy and abundance were higher in forest than in non-forest habitats. Our case study illustrates the need to evaluate relationships between sampling design, cost, and occupancy-abundance estimates when designing and implementing large-scale occupancy-abundance monitoring programs.

The environment plays a key role in supporting children's participation and can serve as a focus of intervention. This study aimed to elicit the perceptions and experiences of occupational therapists who had applied the PREP approach--Pathways and Resources for Engagement and Participation. PREP is a novel 12-week intervention for youth with physical disabilities, aimed at improving participation in leisure community-based activities by modifying aspects of the environment. Using a qualitative post-intervention only design, 12 therapists took part in individual semi-structured interviews, in which the therapists reflected on their experience using PREP to enable participation. A thematic analysis was conducted. Four themes emerged from the data; two of which were informative in nature, describing elements of the PREP intervention that target multi-layered composition of the environment and use strategies that involve leveraging resources and problem solving. The two remaining themes were reflective in nature, illustrating a new take on the Occupational Therapy role and re-positioning the concept of participation in therapy practices. Results emphasize aspects of the environment that can serve as effective targets of intervention, guided by the PREP approach. Findings can broaden the scope and focus of occupational therapy practice by redefining views on participation and the environment.

Conserving relativistic many-body approach: Equation of state, spectral function, and occupation probabilities of nuclear matter

International Nuclear Information System (INIS)

de Jong, F.; Malfliet, R.

1991-01-01

Starting from a relativistic Lagrangian we derive a ''conserving'' approximation for the description of nuclear matter. We show this to be a nontrivial extension over the relativistic Dirac-Brueckner scheme. The saturation point of the equation of state calculated agrees very well with the empirical saturation point. The conserving character of the approach is tested by means of the Hugenholtz--van Hove theorem. We find the theorem fulfilled very well around saturation. A new value for compression modulus is derived, K=310 MeV. Also we calculate the occupation probabilities at normal nuclear matter densities by means of the spectral function. The average depletion κ of the Fermi sea is found to be κ∼0.11

Indoor environmental conditions (thermal, noise, light, and indoor air quality) may affect workers' comfort, and consequently their health and well-being, as well as their productivity. This study aimed to assess the relations between perceived indoor environment and occupants' comfort, and to examine the modifying effects of both personal and building characteristics. Within the framework of the European project OFFICAIR, a questionnaire survey was administered to 7441 workers in 167 "modern" office buildings in eight European countries (Finland, France, Greece, Hungary, Italy, The Netherlands, Portugal, and Spain). Occupants assessed indoor environmental quality (IEQ) using both crude IEQ items (satisfaction with thermal comfort, noise, light, and indoor air quality), and detailed items related to indoor environmental parameters (e.g., too hot/cold temperature, humid/dry air, noise inside/outside, natural/artificial light, odor) of their office environment. Ordinal logistic regression analyses were performed to assess the relations between perceived IEQ and occupants' comfort. The highest association with occupants' overall comfort was found for "noise", followed by "air quality", "light" and "thermal" satisfaction. Analysis of detailed parameters revealed that "noise inside the buildings" was highly associated with occupants' overall comfort. "Layout of the offices" was the next parameter highly associated with overall comfort. The relations between IEQ and comfort differed by personal characteristics (gender, age, and the Effort Reward Imbalance index), and building characteristics (office type and building's location). Workplace design should take into account both occupant and the building characteristics in order to provide healthier and more comfortable conditions to their occupants.

Based on a database accumulated from several recent surveys of office buildings located in a temperate climate (Denmark), the effect on occupant perceptions and symptom prevalence was compared in buildings with natural and with mechanical ventilation in which earlier studies have shown a discrepancy in the degree of perceived control. The database was composed of 1272 responses obtained in 24 buildings of which 15 had mechanical ventilation (997 responses) and nine had natural ventilation (275 responses). The number of occupant-reported control opportunities was higher in buildings with natural ventilation. Analysis of occupant responses, after grouping according to categories determined by the degree of satisfaction with the perceived control, showed that it was more likely the degree of control satisfaction that affected the prevalence of adverse perceptions and symptoms. Thus, the degree of control, as perceived by occupants, seemed more important for the prevalence of adverse symptoms and building-related symptoms than the ventilation mode per se. This result indicates that even though the development and application of new indoor environment sensors and HVAC control systems may allow for fully automated IEQ control, such systems should not compromise occupants' perception of having some degree of control of their indoor environment.

US National energy policy: conservation and environment

International Nuclear Information System (INIS)

Michna, J.; Bednarz, L.M.

2004-01-01

The paper presents extracts from an extended review devoted to recent changes and current trends in the national energy policy pursued in the USA. In 2001 the President Bush proposed an energy strategy for the period to 2025 that would promote energy conservation, repair and expand energy infrastructure, and increase energy supply while protecting the environment. The material stresses the importance of a sound national energy policy addressing supply, energy distribution and conservation. Well - illustrated data are given on the energy production and consumption (total, per capita, per $, by category, by fuel, etc.) and on the emissions (by sector, by fuel, by region, etc.). Giving an accurate account of the current situation with energy in America and a vision of its development for the first quarter of our century, these data are helpful for analyzing the national energy policies in other countries, post - transitional included.

This article aims to define occupational rhinitis, classify its various causes, review the steps in its diagnosis, and describe its nonpharmacologic and pharmacologic principles of management. Occupational rhinitis frequently coexists with asthma but also occurs alone. Although it does not have the same impact as occupational asthma, occupational rhinitis causes distress, discomfort, and work inefficiency. By concentrating on the patient's workplace, the clinician has an opportunity to practice preventive medicine: to recognize substances in the patient's micro- and macroenvironment that are causing the problems and then to intervene by altering the environment or removing the patient from the environment.

Social-psychological principles of community-based conservation and conservancy motivation: attaining goals within an autonomy-supportive environment.

Science.gov (United States)

Decaro, Daniel; Stokes, Michael

2008-12-01

Community-based natural resource conservation programs in developing nations face many implementation challenges underpinned by social-psychological mechanisms. One challenge is garnering local support in an economically and socially sustainable fashion despite economic hardship and historical alienation from local resources. Unfortunately, conservationists' limited understanding of the social-psychological mechanisms underlying participatory conservation impedes the search for appropriate solutions. We address this issue by revealing key underlying social-psychological mechanisms of participatory conservation. Different administrative designs create social atmospheres that differentially affect endorsement of conservation goals. Certain forms of endorsement may be less effective motivators and less economically and socially sustainable than others. From a literature review we found that conservation initiatives endorsed primarily for nonautonomous instrumental reasons, such as to avoid economic fines or to secure economic rewards, are less motivating than those endorsed for autonomous reasons, such as for the opportunity for personal expression and growth. We suggest that successful participatory programs promote autonomous endorsement of conservation through an administrative framework of autonomy support-free and open democratic participation in management, substantive recognition and inclusion of local stakeholder identity, and respectful, noncoercive social interaction. This framework of the autonomy-supportive environment (self-determination theory) has important implications for future research into program design and incentive-based conservation and identifies a testable social-psychological theory of conservancy motivation.

Studies examining workers' diet according to smaller occupational groups within "large occupational categories" are sparse. The aim of this study was to examine the potential differences in workers' diets based on the classification of workers into smaller occupational groups that comprise "large occupational categories". The subjects of this study were working fathers who had participated in the Japan Environment and Children's Study (N = 38,656). Energy and nutrient intake were calculated based on data collected from the Food Frequency Questionnaire. Occupations were classified according to the Japanese Standard Occupational Classification. Logistic regression analyses were performed to examine the adherence to current dietary recommendations within smaller occupational groups. In particular, significant differences were observed among the categorical groups of "professional and engineering workers", "service workers", and "agricultural, forestry, and fishery workers". In "professional and engineering workers", teachers showed higher odds of adherence to calcium intake recommendations compared with nurses (OR, 2.54; 95% CI, 2.02⁻3.14; p < 0.001). In "agricultural, forestry, and fishery workers", agriculture workers showed higher odds of adherence to calcium (OR, 2.15; 95% CI, 1.46⁻3.15; p < 0.001) and vitamin C (OR 1.90, 95% CI 1.31⁻2.74, p = 0.001) intake recommendations compared with forestry and fishery workers. These findings may be beneficial from a research perspective as well as in the development of more effective techniques to improve workers' diet and health.

Over the past 30 years, the advent of fluoroscopically guided interventional procedures has resulted in dramatic increments in both X-ray exposure and physical demands that predispose interventionists to distinct occupational health hazards. The hazards of accumulated radiation exposure have been known for years, but until recently the other potential risks have been ill-defined and under-appreciated. The physical stresses inherent in this career choice appear to be associated with a predilection to orthopedic injuries, attributable in great part to the cumulative adverse effects of bearing the weight and design of personal protective apparel worn to reduce radiation risk and to the poor ergonomic design of interventional suites. These occupational health concerns pertain to cardiologists, radiologists and surgeons working with fluoroscopy, pain management specialists performing nonvascular fluoroscopic procedures, and the many support personnel working in these environments. This position paper is the work of representatives of the major societies of physicians who work in the interventional laboratory environment, and has been formally endorsed by all. In this paper, the available data delineating the prevalence of these occupational health risks is reviewed and ongoing epidemiological studies designed to further elucidate these risks are summarized. The main purpose is to publicly state speaking with a single voice that the interventional laboratory poses workplace hazards that must be acknowledged, better understood and mitigated to the greatest extent possible, and to advocate vigorously on behalf of efforts to reduce these hazards. Interventional physicians and their professional societies, working together with industry, should strive toward the ultimate zero radiation exposure work environment that would eliminate the need for personal protective apparel and prevent its orthopedic and ergonomic consequences. © 2008 Wiley-Liss, Inc.

Schwenk, W Scott; Donovan, Therese M

2011-10-01

Rapidly changing landscapes have spurred the need for quantitative methods for conservation assessment and planning that encompass large spatial extents. We devised and tested a multispecies framework for conservation planning to complement single-species assessments and ecosystem-level approaches. Our framework consisted of 4 elements: sampling to effectively estimate population parameters, measuring how human activity affects landscapes at multiple scales, analyzing the relation between landscape characteristics and individual species occurrences, and evaluating and comparing the responses of multiple species to landscape modification. We applied the approach to a community of terrestrial birds across 25,000 km(2) with a range of intensities of human development. Human modification of land cover, road density, and other elements of the landscape, measured at multiple spatial extents, had large effects on occupancy of the 67 species studied. Forest composition within 1 km of points had a strong effect on occupancy of many species and a range of negative, intermediate, and positive associations. Road density within 1 km of points, percent evergreen forest within 300 m, and distance from patch edge were also strongly associated with occupancy for many species. We used the occupancy results to group species into 11 guilds that shared patterns of association with landscape characteristics. Our multispecies approach to conservation planning allowed us to quantify the trade-offs of different scenarios of land-cover change in terms of species occupancy.

To determine the optimal situation for the energy supply in the working area of the IJsselmij and Sep the study on the title subject was carried out. To influence the energy demand demand-side management (DSM) as part of integrated resource planning (IRP) is applied. Several scenarios to determine whether new production capacity must be installed or conservation options and activities should be realized are elaborated and calculated by means of the COMPASS model. E3T compiled input data for the demand-side of the model: energy consumption and energy conservation, investment cost and operational cost per user, number of installations and the development of the penetration of the conservation options between 1990 and 2010, and required subsidies and promotional costs of the IJsselmij to introduce such options. Six of the options were selected and elaborated in detail. The results are presented in this report for the options: coverage of cooling and freezing equipment at night, frequency control of electric motors, decentralized heat production by means of advanced burners, indoor climate control in the built environment, reflectors for TL-lighting systems in the built environment, and behavioral change in industrial companies. In part 1 an overview is given of the economics, the selection and elaboration of the energy conservation options. 9 figs., 53 tabs., 71 refs., 1 appendix

Dementia residential facilities can be described as traditional or non-traditional facilities. Non-traditional facilities aim to utilise principles of environmental design to create a milieu that supports persons experiencing cognitive decline. This study aimed to compare these two environments in rural Australia, and their influence on residents' occupational engagement. The Residential Environment Impact Survey (REIS) was used and consists of: a walk-through of the facility; activity observation; interviews with residents and employees. Thirteen residents were observed and four employees interviewed. Resident interviews did not occur given the population diagnosis of moderate to severe dementia. Descriptive data from the walk-through and activity observation were analysed for potential opportunities of occupational engagement. Interviews were thematically analysed to discern perception of occupational engagement of residents within their facility. Both facilities provided opportunities for occupational engagement. However, the non-traditional facility provided additional opportunities through employee interactions and features of the physical environment. Interviews revealed six themes: Comfortable environment; roles and responsibilities; getting to know the resident; more stimulation can elicit increased engagement; the home-like experience and environmental layout. These themes coupled with the features of the environment provided insight into the complexity of occupational engagement within this population. This study emphasises the influence of the physical and social environment on occupational engagement opportunities. A non-traditional dementia facility maximises these opportunities and can support development of best-practice guidelines within this population. © 2015 Occupational Therapy Australia.

A year-long field study of the thermal environment in university classrooms was conducted from March 2005 to May 2006 in Chongqing, China. This paper presents the occupants' thermal sensation votes and discusses the occupants' adaptive response and perception of the thermal environment in a naturally conditioned space. Comparisons between the Actual Mean Vote (AMV) and Predicted Mean Vote (PMV) have been made as well as between the Actual Percentage of Dissatisfied (APD) and Predicted Percentage of Dissatisfied (PPD). The adaptive thermal comfort zone for the naturally conditioned space for Chongqing, which has hot summer and cold winter climatic characteristics, has been proposed based on the field study results. The Chongqing adaptive comfort range is broader than that of the ASHRAE Standard 55-2004 in general, but in the extreme cold and hot months, it is narrower. The thermal conditions in classrooms in Chongqing in summer and winter are severe. Behavioural adaptation such as changing clothing, adjusting indoor air velocity, taking hot/cold drinks, etc., as well as psychological adaptation, has played a role in adapting to the thermal environment.

Kwo, Elizabeth; Christiani, David

2017-03-01

The interplay between genetic susceptibilities and environmental exposures in the pathogenesis of a variety of diseases is an area of increased scientific, epidemiologic, and social interest. Given the variation in methodologies used in the field, this review aims to create a framework to help understand occupational exposures as they currently exist and provide a foundation for future inquiries into the biological mechanisms of the gene-environment interactions. Understanding of this complex interplay will be important in the context of occupational health, given the public health concerns surrounding a variety of occupational exposures. Studies found evidence that suggest genetics influence the progression of disease postberyllium exposure through genetically encoded major histocompatibility complex, class II, DP alpha 2 (HLA-DP2)-peptide complexes as it relates to T-helper cells. This was characterized at the molecular level by the accumulation of Be-responsive CD4 T cells in the lung, which resulted in posttranslational change in the HLA-DPB1 complex. These studies provide important evidence of gene-environment association, and many provide insights into specific pathogenic mechanisms. The following includes a review of the literature regarding gene-environment associations with a focus on pulmonary diseases as they relate to the workplace.

The database was composed of 1353 responses obtained in 25 buildings of which 15 had mechanical ventilation (997 responses) and 9 had natural ventilation (275 responses). Analysis of occupant responses, after grouping according to categories determined by the degree...... of satisfaction with the perceived control, showed that the degree of control satisfaction, but rarely building category (natural vs. mechanical ventilation), affected the prevalence of adverse perceptions and symptoms. Thus, the degree of control, as perceived by occupants, was more important for the prevalence...

The primary responsibility of the Health, Safety, and Environment (HSE) Division at the Los Alamos National Laboratory is to provide comprehensive occupational health and safety programs, waste processing, and environmental protection. These activities are designed to protect the workers, the public, and the environment. Evaluation of respiratory protective equipment included the XM-30 and M17A1 military masks, use of MAG-1 spectacles in respirators, and eight self-contained units. The latter units were used in an evaluation of test procedures used for Bureau of Mines approval of breathing apparatuses. Analyses of air samples from field studies of a modified in situ oil shale retorting facility were performed for total cyclohexane extractables and selected polynuclear aromatic hydrocarbons. Aerosols generation and characterization of effluents from oil shale processing were continued as part of an inhalation toxicology study. Additional data on plutonium excretion in urine are presented and point up problems in using the Langham equation to predict plutonium deposition in the body from long-term excretion data. Environmental surveillance at Los Alamos during 1983 showed the highest estimated radiation dose from Laboratory operations to be about 26% of the natural background radiation dose. Several studies on radionuclides and their transport in the Los Alamos environment are described. The chemical quality of surface and ground water near the geothermal hot dry rock facility is described. Short- and long-term consequences to man from releases of radionuclides into the environment can be simulated by the BIOTRAN computer model, which is discussed brirfly

Economy of conservation options in the industry and the built environment. Part 1

International Nuclear Information System (INIS)

1994-03-01

To determine the optimal situation for the energy supply in the working area of the IJsselmij and Sep the study on the title subject was carried out. To influence the energy demand demand-side management (DSM) as part of integrated resource planning (IRP) is applied. Several scenarios to determine whether new production capacity must be installed or conservation options and activities should be realized are elaborated and calculated by means of the COMPASS model. E3T compiled input data for the demand-side of the model: energy consumption and energy conservation, investment cost and operational cost per user, number of installations and the development of the penetration of the conservation options between 1990 and 2010, and required subsidies and promotional costs of the IJsselmij to introduce such options. The economics of the energy conservation options are given in chapter 2. Six of the options were selected and elaborated in detail in a separate publication (part 2): coverage of cooling and freezing equipment at night, frequency control of electric motors, decentralized heat production by means of advanced burners, indoor climate control in the built environment, reflectors for TL-lighting systems in the built environment, and behavioral change in industrial companies. 2 figs., 7 tabs., 7 refs., 4 appendices

Gene-environment interaction from international cohorts: impact on development and evolution of occupational and environmental lung and airway disease.

Science.gov (United States)

Gaffney, Adam; Christiani, David C

2015-06-01

Environmental and occupational pulmonary diseases impose a substantial burden of morbidity and mortality on the global population. However, it has been long observed that only some of those who are exposed to pulmonary toxicants go on to develop disease; increasingly, it is being recognized that genetic differences may underlie some of this person-to-person variability. Studies performed throughout the globe are demonstrating important gene-environment interactions for diseases as diverse as chronic beryllium disease, coal workers' pneumoconiosis, silicosis, asbestosis, byssinosis, occupational asthma, and pollution-associated asthma. These findings have, in many instances, elucidated the pathogenesis of these highly complex diseases. At the same time, however, translation of this research into clinical practice has, for good reasons, proceeded slowly. No genetic test has yet emerged with sufficiently robust operating characteristics to be clearly useful or practicable in an occupational or environmental setting. In addition, occupational genetic testing raises serious ethical and policy concerns. Therefore, the primary objective must remain ensuring that the workplace and the environment are safe for all.

For the assessment of personal exposure, information about the concentration of pollutants when people are in given indoor environments (occupancy time) are of prime importance. However this kind of data frequently is not reported. The aim of this study was to assess differences in particle characteristics between occupancy time and the total monitoring period, with the latter being the most frequently used averaging time in the published data. Seven indoor environments were selected in Sweden and Finland: an apartment, two houses, two schools, a supermarket, and a restaurant. They were assessed for particle number and mass concentrations and number size distributions. The measurements using a Scanning Mobility Particle Sizer and two photometers were conducted for seven consecutive days during winter in each location. Particle concentrations in residences and schools were, as expected, the highest during occupancy time. In the apartment average and median PM2.5 mass concentrations during the occupancy time were 29% and 17% higher, respectively compared to total monitoring period. In both schools, the average and medium values of the PM2.5 mass concentrations were on average higher during teaching hours compared to the total monitoring period by 16% and 32%, respectively. When it comes to particle number concentrations (PNC), in the apartment during occupancy, the average and median values were 33% and 58% higher, respectively than during the total monitoring period. In both houses and schools the average and median PNC were similar for the occupancy and total monitoring periods. General conclusions on the basis of measurements in the limited number of indoor environments cannot be drawn. However the results confirm a strong dependence on type and frequency of indoor activities that generate particles and site specificity. The results also indicate that the exclusion of data series during non-occupancy periods can improve the estimates of particle concentrations and

Full Text Available Objective: To assess the effect of aquatic environment while an occupational therapeutic scenario in the development of body scheme of a child with Down Syndrome, considering the therapeutic properties of water. Description of the case: An interventionist research, with a qualitative and descriptive approach, conducted in an adapted pool of the Núcleo de Atenção Médica Integrada (NAMI of Fortaleza University (UNIFOR, Ceara, during the period of March to May, 2005. The subject of the study was a female child, aged 10 years old, diagnosed with Down Syndrome. Data collection had as instruments an interview guide for anamnesis, an evaluation form of psychomotor development, besides a field diary to record clinical observations during the sessions. This information was organized and analyzed based on clinical reasoning of occupational therapists and then described as a case study. We observed an evolution in the development of skills related to body scheme, such as the perception of fine parts of her own body, as well as large parts in someone else’s body, the imitation of positions, finishing with more active participation in activities of daily living. Final Considerations: We verified the effectiveness of occupational therapeutic activities conducted in aquatic environment for the development of the body scheme of the child in the study. This may be useful for conducting further research on the subject – whose literature is scarce – and contributing to the crescent update of occupational therapy practices.

The 222 Rn concentration in outdoor workplaces were measured in Aomori Prefecture, Japan as a part of a program on measurement of natural radiation background dose to people in the prefecture where Japan's first nuclear fuel cycling facilities are now under construction. 222 Rn concentrations were measured in 116 outdoor workplaces by passive Rn detectors for 10 months, which represented agricultural, forestry, fishery and construction/transportation workplaces. The 222 Rn concentrations in outdoor workplaces were generally lower than those in indoor environments. The dose to workers was estimated by using the results of the passive detectors as well as diurnal variation of 222 Rn and equilibrium factor measured with active-type detectors. The average dose from 222 Rn and its progenies to people in Aomori Prefecture was estimated as 0.39 mSv x y -1 based on the obtained results and results in indoor environments. The contribution of 222 Rn in outdoor workplaces to the total dose was 3.3% because of low occupancy ratio. (author)

The thermal environment and occupant perceptions in European office buildings

2002-02-01

The results from a large field study of thermal comfort in European office buildings are reported. Environmental conditions and occupant perceptions were collected over fourteen months from twenty-six different office buildings located in France, Greece, Portugal, Sweden and the UK. This thesis focuses on the thermal measurements and occupant perceptions; however, some of the additional variables with strong connections to thermal sensation are also examined. A summary of human comfort is presented to help place this thesis in appropriate context. The summary presents thermal comfort issues within a broad framework of environmental comfort including physical, physiological, behavioural, psychological and other variables. A more narrowly focused overview of current thermal comfort research is also included. The work attempts to show relationships and produce useful information from the data set by using rather simple statistics and graphical methods. The objective is to quite literally use the data set to illustrate the actual thermal conditions in European office buildings and the occupant perceptions of those conditions. The data are examined in some detail with key relationships identified and explored. Significant differences between countries, both for the physical conditions and the perceptions of those conditions are identified. In addition, the variation over the course of the year for each country is explored. The variations occur in complex ways, which make simple, all encompassing explanations impossible. The nature and size of the variations make the application of simple Europe wide models of thermal comfort questionable. It appears that individuals in different European countries have different expectations for their indoor office thermal environment. This data set will be further explored in a more complete study, which will examine the other measured variables.

An official residence is a housing provided by the state and used as a residence occupied by the official duties of officials and civil servants during their service in the city. The property rights of the official residence have limit, only valid while the residents serve in the city. The process of adaptation becomes indispensable because, in the early days of occupying the housing, residents will face a new social environment, which may be different from their previous environment. Furthermore, backgrounds such as economic, cultural, and social factors of each occupant will also determine the adaptation process that occurs. This research aims to find out and analyze adaptation process of the official residence’s dwellers to its environment. This study used the descriptive-qualitative method by interviewing ten occupants who selected by purposive sampling method. Results of research indicated that the most adaptation process occurs adaptation by the reaction such as adding the number of room and service area.

Employee performance can be the supporting factor of company performance. However, employee performance can be affected by several factors. Employees can have optimal performance if they feel safe, have good working environment and have discipline. The purposes of this research are to analyze the effect of occupational health and safety, work environment and discipline on the employee performance in PPIC Thermo section in a consumer goods company and to find the dominant variable which primarily affects employee performance. This research was conducted by taking data from 47 respondents. The data were collected using questionnaire. The techniques in data analysis is multiple linear regression with SPSS software. The result shows that occupational health and safety, work environment and discipline are simultaneously significant to the employee performance. Discipline holds the dominant factor which affects employee performance.

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

Wetlands conserved using water level manipulation, cattle exclusion, naturalization of uplands, and other techniques under the North American Waterfowl Management Plan ("conservation project wetlands") are important for ducks, geese, and swans ("waterfowl"). However, the assumption that conservation actions for waterfowl also benefit other wildlife is rarely quantified. We modeled detection and occupancy of species at sites within 42 conservation project wetlands compared to sites within 52 similar nearby unmanaged wetlands throughout southern Ontario, Canada, and small portions of the adjacent U.S., using citizen science data collected by Bird Studies Canada's Great Lakes Marsh Monitoring Program, including 2 waterfowl and 13 non-waterfowl marsh-breeding bird species (n = 413 sites) and 7 marsh-breeding frog species (n = 191 sites). Occupancy was significantly greater at conservation project sites compared to unmanaged sites in 7 of 15 (47%) bird species and 3 of 7 (43%) frog species, with occupancy being higher by a difference of 0.12-0.38 across species. Notably, occupancy of priority conservation concern or at-risk Black Tern (Chlidonias niger), Common Gallinule (Gallinula galeata), Least Bittern (Ixobrychus exilis), Sora (Porzana carolina), and Western Chorus Frog (Pseudacris triseriata) was significantly higher at conservation project sites compared to unmanaged sites. The results demonstrate the utility of citizen science to inform wetland conservation, and suggest that actions under the North American Waterfowl Management Plan are effective for conserving non-waterfowl species.

Occupational applications of ultraviolet radiation

International Nuclear Information System (INIS)

Eriksen, P.

1987-01-01

A large population of workers are exposed to ultraviolet radiation in various occupational environments which often necessitates protection. Since ultraviolet radiation may create other environmental problems an occupational hazard- and protection evaluation can be complicated. Threshold Limit Values adopted by the American Conference of Governmental Industrial Hygienists (ACGIH) on ultraviolet radiation are used in most countries as guidelines for risk assessment and control measures. This review addresses the levels of ultraviolet radiation met in occupational environments, its measurement and evaluation, and discusses different protection methods. Ultraviolet lasers are beginning to find their way into industrial processes but are still limited in number and they will not be covered here. Emphasis is on broad band incoherent radiation in high risk environments such as welding, and on the evaluation of protective eyewear, see-through curtains and plastics. Other occupational risks associated with the emission of ultraviolet radiation are discussed

The 222 Rn concentrations in indoor workplaces were measured in Aomori Prefecture, Japan, and the results are reported here. This survey was part of a program to measure background natural radiation dose rate in the prefecture where the first Japanese nuclear fuel cycling facilities are now under construction. The survey of the 222 Rn concentrations in indoor workplaces was carried out at 107 locations from 1996 to 1998. The 222 Rn concentrations were measured for approximately one year at each site with passive Rn detectors, which used a polycarbonate film for counting α-rays and could separate concentrations of 222 Rn from 220 Rn. Weeklong measurements of 222 Rn concentration and working level were carried out with active detectors to get the ratio of 222 Rn concentration during working hours to non-working hours as well as equilibrium factors in selected locations. Diurnal variation of 222 Rn concentration depended on building structure, air-conditioning, time of day and day of the week (week days or weekend). The 222 Rn concentration during working hours was generally lower than that in non-working hours. Although the annual average 222 Rn concentration in indoor occupational environments was higher than that in dwellings, radiation dose for Aomori Prefecture residents from Rn in the former was 14% of the total indoor dose by Rn because of the lower concentration in working hours and lower occupancy factor

This article traces the development of the European Centre for Occupational Health, Safety and the Environment (ECOHSE) at the University of Glasgow. ECOHSE recently has been designated a Thematic Network by the European Union which is providing administrative support through 2004. The de facto de-regulation that accompanied emergent capitalism in Eastern Europe created opportunities for exploitation of the work force. Voluntary efforts of a loose network of occupational and environmental health academics led to a series of yearly conferences to discuss these problems and the lack of research about them. Then, in 1999, a more formal organization was established at Glasgow to pursue continuity and funding. The first occupational and environmental health conference under ECOHSE was held last year in Lithuania, and selected presentations of that meeting are offered in this journal. A second ECOHSE conference will be held this fall in Romania.

Energy Saving Alignment Strategy: Achieving energy efficiency in urban buildings by matching occupant temperature preferences with a building’s indoor thermal environment

Xu, Xiaoqi; Culligan, Patricia J.; Taylor, John E.

2014-01-01

Highlights: • A novel strategy for energy savings in multi-family buildings is presented. • A household’s thermal preferences are matched with a unit’s thermal environment. • Potential energy savings are examined using public housing as a test case. • 2.1–42.0% primary energy savings are shown, depending on climate location. - Abstract: Existing strategies for residential energy savings through physical renovation or motivating occupant energy conservation behavior can be costly and/or have transitory effects. Focusing on multi-family dwellings, an important subset of the urban residential sector, we propose an Energy Saving Alignment Strategy (ESAS) that has advantageous cost-effectiveness and a long-lasting influence. By aligning the distribution of residents’ thermostat preferences with the indoor temperature, ESAS aims to maximize thermal comfort and, accordingly, energy savings in multi-family buildings where indoor temperatures vary between apartments as a function of apartment orientation and floor level. Using a case study of a 1084-apartment public housing complex in New York, we classify both occupants’ thermostat preferences and apartments’ operative temperatures into five groups, and optimize energy efficiency by assigning each group of occupants to the group of apartments that best aligns with their thermostat preference. We test ESAS in eight cities representing all four U.S. census regions and six climate zones. Simulation results reveal 2.1–42.0% in energy savings compared to random apartment assignments depending on geographic location, with the highest energy reductions occurring in cities with mild climates, where the range of occupant thermostat preferences coincides with the natural indoor temperature range. We conclude by providing suggested guidelines on how ESAS might work in practice, and recommendations for extending ESAS research

Occupation and the relevance of primatology to occupational therapy.

Science.gov (United States)

Wood, W

1993-06-01

The adaptive functions of occupation during the phylogenetic history of the human species and the ontogenetic development of individual primates re examined through a review of relevant research of wild and captive nonhuman primates. This review suggests that the effectiveness of occupation as a therapeutic medium throughout life span development is fundamentally tied to humankind's phylogenetic history. It is accordingly argued that there is considerable justification to maintain occupational therapy's historical commitment to therapeutic occupation as the profession's primary treatment modality. To support this commitment, questions to guide practice and research are identified that emanate from the primate literature and that are highly germane to the therapeutic process in occupational therapy. These questions address: (a) the relationship between the press of the various environments in which occupational therapists practice and subsequent opportunities availed to patients for engagement in occupation; (b) the relationship between the extent to which patients are or are not empowered to exert real control over their use of time and their eventual development of disabling conditions; and (c) the therapeutic efficacy of occupation as compared with other treatment approaches that are not comparably holistic.

Monitoring audiometry for occupational hearing loss: A case for eliminating 500 Hz

Science.gov (United States)

Stephenson, Mark

2003-04-01

Audiometric monitoring is an important element in hearing conservation programs. Nearly every existing hearing conservation standard dictate that hearing thresholds should be measured at specific frequencies, and that 500 Hz be among those frequencies tested. Actual and estimated noise-induced permanent threshold shifts were evaluated as a function of exposure duration and exposure level. The results demonstrate 500 Hz to be of little value in assessing noise-induced hearing loss for typical industrial noise exposures of up to 40 years, at least for time-weighted average exposures of up to 100 dBA. Furthermore, few hearing conservation programs currently require audiometric monitoring to be performed in an environment that meets ANSI standards for maximum permissible background noise levels. This is particularly likely to compromise hearing testing at 500 Hz. As a result, this paper argues against the need for testing at 500 Hz, and recommends it be eliminated as a required test frequency in audiometric monitoring for noise-induced occupational hearing loss.

Full Text Available The conservation of the Speleological Heritage involves bioecological, geomorphological and anthropogenic studies, both from inside the caves and from the external environments that surround them. This study presents a method to rank caves according to their priority for conservation and restoration. Nine caves were evaluated: indicators related to the environmental impacts and the vulnerability status presented by those caves (intrinsic features and the values scored in a ‘Cave Conservation Index’ (CCI were established. We also used a rapid assessment protocol to measure cave vulnerability for prioritization of conservation/restoration actions (RAP-cr comparing natural cavities with the same lithology, due to “strictu sensu” peculiarities. Based on the protocols applied in caves of the municipality of Laranjeiras, Sergipe, Northeastern Brazil, we concluded that the present method attended to the needs for the classification of the caves into categories of conservation/restoration status, using little time and financial effort, through rapid diagnostics that facilitate the comparisons. In this perspective, the CCI can be used to indicate areas that should be protected and caves that should be prioritized to have initiated activities of conservation and restoration.

The values of occupational therapy: Perceptions of occupational therapists in Quebec.

Drolet, Marie-Josée; Désormeaux-Moreau, Marjorie

2016-07-01

Recently, there has been increasing interest in the values of occupational therapy and the values held by occupational therapists. A wide range of values has been reported in the literature. Furthermore, despite the fact that values are an important part of professional identity, empirical studies have demonstrated that several occupational therapists possess an ambiguous professional identity. This study was undertaken to explore the values of Canadian occupational therapists, specifically French-speaking occupational therapists in Quebec. Semi-structured interviews were conducted with 26 occupational therapists. Their narratives were subject to hermeneutic analysis, a method of textual analysis common in philosophical research. A total of 16 values were identified in the discourses of the occupational therapists interviewed: autonomy; human dignity; occupational participation; social justice and equity; professionalism; holism; partnership, environment, or ecological approach; quality of life; solicitude; honesty; integrity; health; creativity; professional autonomy; effectiveness; and spirituality. The results of this study are, in general, consistent with those reported in the few other empirical studies that have documented the values perceptions of occupational therapists. Finally, the explanation of the values of occupational therapists may reinforce their professional identity and favour best, or at least desirable, professional practices related to ethics and culture.

The same reasons that prompt older people to give up driving can also result in difficulties with accessing public transport. Difficulties using public transport can limit older people's participation in society, thereby impacting negatively on their health. Focusing on public buses, this review explicates the link between bus usability and the health of older people and frames existing evidence on bus usability issues. The Person-Environment-Occupation (PEO) model offers a framework by which bus usability can be assessed. A combination of person-centred, environmental, and occupation-related factors, including bus design, service provision and performance, information, and the attitudes of staff and the community, impact on older people's ability to catch buses. More systematic research needs to take place in order to develop a comprehensive understanding of bus usability. Occupational therapy has a key role to play in conceptualizing, implementing, and evaluating improvements in bus usability for older people.

This paper describes an investigation of the effect on electric lighting demand of applying occupancy models of various resolution to climate-based daylight modelling. The lighting demand was evaluated for a building zone with the occupant always present, with occupancy corresponding to absence...... factors, based on an estimated annual mean occupancy, based on estimated 1-hour mean occupancy, and based on 2-min occupancy intervals. The results showed little difference in the annual electric lighting demand when the same occupancy profile was used every day, as opposed to when profiles were used...... where occupancy varied every day. Furthermore, the results showed that annual electric lighting demand was evaluated slightly conservatively when a mean absence factor was applied as opposed to using dynamic occupancy profiles....

Forest degradation is arguably the greatest threat to biodiversity, ecosystem services, and rural livelihoods. Therefore, increasing understanding of how organisms respond to degradation is essential for management and conservation planning. We were motivated by the need for rapid and practical analytical tools to assess the influence of management and degradation on biodiversity and system state in areas subject to rapid environmental change. We compared bird community composition and size in managed (ejido, i.e., communally owned lands) and unmanaged (national park) forests in the Sierra Tarahumara region, Mexico, using multispecies occupancy models and data from a 2-year breeding bird survey. Unmanaged sites had on average higher species occupancy and richness than managed sites. Most species were present in low numbers as indicated by lower values of detection and occupancy associated with logging-induced degradation. Less than 10% of species had occupancy probabilities >0.5, and degradation had no positive effects on occupancy. The estimated metacommunity size of 125 exceeded previous estimates for the region, and sites with mature trees and uneven-aged forest stand characteristics contained the highest species richness. Higher estimation uncertainty and decreases in richness and occupancy for all species, including habitat generalists, were associated with degraded young, even-aged stands. Our findings show that multispecies occupancy methods provide tractable measures of biodiversity and system state and valuable decision support for landholders and managers. These techniques can be used to rapidly address gaps in biodiversity information, threats to biodiversity, and vulnerabilities of species of interest on a landscape level, even in degraded or fast-changing environments. Moreover, such tools may be particularly relevant in the assessment of species richness and distribution in a wide array of habitats. © 2014 Society for Conservation Biology.

To examine the effect of parents' occupational and life exposure during six months before pregnancy on executive function of preschool children. Pregnant women involved in the study came from the Ma'anshan Birth Cohort Study,a part of the China-Anhui Birth Cohort Study. Between October 2008 and October 2010, pregnant women who accepted pregnancy care in four municipal medical and health institutions in Ma'anshan city were recruited as study objects. A total of 5,084 pregnant women and 4,669 singleton live births entered in this cohort. Between April 2014 and April 2015, a total of 3,803 pre-school children were followed up. Finally, except 32 preschool children did not have EF evaluation result, there were 3,771 children included in this study. By using self-designed " Maternal health handbook", we researched parents' general demographic characteristics, and life and occupational exposure during six months before pregnancy. To research preschool children's executive function, we used the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P). Univariate and multivariate statistical method was used to analyze the association of parents' life and occupational exposure during six months before pregnancy and preschool children's EF. 3,771 preschool children's detected rate of inhibitory self-control index (ISCI), flexibility index (FI), emergent metacognition index (EMI) and global executive composite (GEC) dysplasia were 4.8% (182), 2.3% (88), 16.5% (623) and 8.6% (324) respectively. During six months before pregnancy, children whose parents were lived in a noise environment (OR=1.86, 95% CI: 1.36-2.54), whose maternal were exposed to pesticides were the risk of ISCI dysplasia(OR=3.60, 95% CI: 1.45-8.95). During six months before pregnancy, children whose maternal were exposed to pesticides (OR=6.72, 95% CI: 2.50-18.07) and whose father were exposed to occupational lead (OR=2.10, 95% CI: 1.25-3.54) were the risk of FI dysplasia. During six months

As there are no well-established modifiable risk factors for prostate cancer, further evidence is needed on possible factors such as occupation. Our study uses one of the largest Canadian worker cohorts to examine occupation, industry, and prostate cancer and to assess patterns of prostate cancer rates. The Canadian Census Health and Environment Cohort (CanCHEC) was established by linking the 1991 Canadian Census Cohort to the Canadian Cancer Database (1969-2010), Canadian Mortality Database (1991-2011), and Tax Summary Files (1981-2011). A total of 37,695 prostate cancer cases were identified in men aged 25-74 based on age at diagnosis. Cox proportional hazards models were used to estimate hazards ratios and 95% confidence intervals. In men aged 25-74 years, elevated risks were observed in the following occupations: senior management (HR = 1.12, 95% CI: 1.04-1.20); office and administration (HR = 1.19, 95% CI: 1.11-1.27); finance services (HR = 1.09, 95% CI: 1.04-1.14); education (HR = 1.05, 95% CI: 1.00-1.11); agriculture and farm management (HR = 1.12, 95% CI: 1.06-1.17); farm work (HR = 1.11, 95% CI: 1.01-1.21); construction managers (HR = 1.07, 95% CI: 1.01-1.14); firefighting (HR = 1.17, 95% CI: 1.01-1.36); and police work (HR = 1.22, 95% CI: 1.09-1.36). Decreased risks were observed across other construction and transportation occupations. Results by industry were consistent with occupation results. Associations were identified for white-collar, agriculture, protective services, construction, and transportation occupations. These findings emphasize the need for further study of job-related exposures and the potential influence of nonoccupational factors such as screening practices. © 2018 The Authors.

Conservation is sexy! What makes this so, and what does this make? An engagement with Celebrity and the environment

Full Text Available This essay offers an engagement with Daniel Brockington′s (2009 recent book Celebrity and the environment. I highlight the book′s contribution to debate regarding processes of human displacement arising through biodiversity conservation under conditions of neoliberal capitalism. I first situate the book in relation to contemporary perspectives on displacement, justice, and human rights, using examples to illustrate complex and dynamic patterns of conservation inclusions and exclusions globally. This is followed by a summary of Brockington′s typology of conservation celebrities, and of the ways in which celebrities assist with the amassing of conservation finance. I proceed to consider the roles of a celebrity-saturated mass media (and mediated ′spectacle of conservation′ in structuring social and consumptive engagements with the ′non-human′ world globally. I draw attention to how diverse peoples in conservation landscapes might become part of the spectacle of conservation by reconfiguring themselves as cultural objects of touristic consumerism in a script not necessarily of their choosing. By way of acknowledging the significance of social networks and alliances in influencing conservation perspectives and practice, I close with a disclaimer regarding my own long-term collaborations with the author of Celebrity and the environment.

Reconciling biodiversity conservation and agricultural expansion in the subarctic environment of Iceland

Full Text Available Intensified agricultural practices have driven biodiversity loss throughout the world, and although many actions aimed at halting and reversing these declines have been developed, their effectiveness depends greatly on the willingness of stakeholders to take part in conservation management. Knowledge of the willingness and capacity of landowners to engage with conservation can therefore be key to designing successful management strategies in agricultural land. In Iceland, agriculture is currently at a relatively low intensity but is very likely to expand in the near future. At the same time, Iceland supports internationally important breeding populations of many ground-nesting birds that could be seriously impacted by further expansion of agricultural activities. To understand the views of Icelandic farmers toward bird conservation, given the current potential for agricultural expansion, 62 farms across Iceland were visited and farmers were interviewed, using a structured questionnaire survey in which respondents indicated of a series of future actions. Most farmers intend to increase the area of cultivated land in the near future, and despite considering having rich birdlife on their land to be very important, most also report they are unlikely to specifically consider bird conservation in their management, even if financial compensation were available. However, as no agri-environment schemes are currently in place in Iceland, this concept is highly unfamiliar to Icelandic farmers. Nearly all respondents were unwilling, and thought it would be impossible, to delay harvest, but many were willing to consider sparing important patches of land and/or maintaining existing pools within fields (a key habitat feature for breeding waders. Farmers' views on the importance of having rich birdlife on their land and their willingness to participate in bird conservation provide a potential platform for the codesign of conservation management with landowners

Towards inclusive occupational therapy: Introducing the CORE approach for inclusive and occupation-focused practice.

Science.gov (United States)

Pereira, Robert B

2017-12-01

Occupation is a human right and a social determinant of health. It is also taken for granted. Having access to, and participating in, occupation, is intricately linked to positive health and wellbeing. Despite theory and evidence to support the link between occupation, health and wellbeing, occupational therapists can struggle with applying an occupation focus in practice and knowing how to use occupational frameworks to enable occupation. The purpose of this paper is to introduce the Capabilities, Opportunities, Resources and Environments (CORE) approach for inclusive and occupation-focused practice. It provides occupational therapists with a means of operationalising occupational enablement and facilitating social inclusion. The CORE approach is introduced by linking its main ideas to Economist and Nobel Prize Laureate Amartya Sen's capabilities approach, as well as findings from the author's doctoral research into entrenched disadvantage and social inclusion. Practical questions guided by the CORE approach's acronym are given to explore how the approach can be utilised alongside other occupational models and frameworks to encourage strategies for effective enablement through occupation for social inclusion. As experts in enabling occupation, occupational therapists can use the CORE approach to design occupation-focused interventions and promote inclusive occupational therapy. © 2017 Occupational Therapy Australia.

Conserving tigers in working landscapes.

Tiger (Panthera tigris) conservation efforts in Asia are focused on protected areas embedded in human-dominated landscapes. A system of protected areas is an effective conservation strategy for many endangered species if the network is large enough to support stable metapopulations. The long-term conservation of tigers requires that the species be able to meet some of its life-history needs beyond the boundaries of small protected areas and within the working landscape, including multiple-use forests with logging and high human use. However, understanding of factors that promote or limit the occurrence of tigers in working landscapes is incomplete. We assessed the relative influence of protection status, prey occurrence, extent of grasslands, intensity of human use, and patch connectivity on tiger occurrence in the 5400 km(2) Central Terai Landscape of India, adjacent to Nepal. Two observer teams independently surveyed 1009 km of forest trails and water courses distributed across 60 166-km(2) cells. In each cell, the teams recorded detection of tiger signs along evenly spaced trail segments. We used occupancy models that permitted multiscale analysis of spatially correlated data to estimate cell-scale occupancy and segment-scale habitat use by tigers as a function of management and environmental covariates. Prey availability and habitat quality, rather than protected-area designation, influenced tiger occupancy. Tiger occupancy was low in some protected areas in India that were connected to extensive areas of tiger habitat in Nepal, which brings into question the efficacy of current protection and management strategies in both India and Nepal. At a finer spatial scale, tiger habitat use was high in trail segments associated with abundant prey and large grasslands, but it declined as human and livestock use increased. We speculate that riparian grasslands may provide tigers with critical refugia from human activity in the daytime and thereby promote tiger occurrence

Conservative treatment and rehabilitation of shoulder problems

2004-01-01

The shoulder joint has an important influence on arm- and handfunction. Therefore, activities of daily living, working and leisure time can be negatively influenced by diseases of the shoulder joint. Problems of the shoulder joint can be induced by muscular dysbalance and poor body posture. There is a strong relationship between shoulder function and body posture. Conservative treatment and rehabilitation of the shoulder joint aims at improving the local dysfunction of the shoulder joint as well as at improving function and social participation. Antiinflammatory and pain medication, exercise, occupational, electro-, ultrasound and shock wave therapy, massage, thermotherapy and pulsed electromagnetic fields are used as conservative treatments. Exercise therapy aims at improving muscular performance, joint mobility and body posture. Occupational therapy aims at improving functional movements for daily living and work. Electrotherapy is primarily used to relieve pain. Shock wave and ultrasound therapy proved to be an effective treatment for patients with calcific tendinitis. The subacromial impingement syndrome can be effectively treated by conservative therapy. (orig.) [de

Gene-environment interaction and biological monitoring of occupational exposures

International Nuclear Information System (INIS)

Hirvonen, Ari

2005-01-01

Biological monitoring methods and biological limit values applied in occupational and environmental medicine have been traditionally developed on the assumption that individuals do not differ significantly in their biotransformation capacities. It has become clear, however, that this is not the case, but wide inter-individual differences exist in the metabolism of chemicals. Integration of the data on individual metabolic capacity in biological monitoring studies is therefore anticipated to represent a significant refinement of the currently used methods. We have recently conducted several biological monitoring studies on occupationally exposed subjects, which have included the determination of the workers' genotypes for the metabolic genes of potential importance for a given chemical exposure. The exposure levels have been measured by urine metabolites, adducts in blood macromolecules, and cytogenetic alterations in lymphocytes. Our studies indicate that genetic polymorphisms in metabolic genes may indeed be important modifiers of individual biological monitoring results of, e.g., carbon disulphide and styrene. The information is anticipated to be useful in insuring that the workplace is safe for everyone, including the most sensitive individuals. This knowledge could also be useful to occupational physicians, industrial hygienists, and regulatory bodies in charge of defining acceptable exposure limits for environmental and/or occupational pollutants

The Environmental Impact on Occupational Therapy Interventions.

The purpose of this study was to investigate how the environment influenced the intervention choices occupational therapists made for patients recovering from a stroke in an inpatient rehabilitation hospital. Three occupational therapists were observed providing intervention for six patients over a 16-month period. Treatment spaces included a therapy gym, gym with kitchen combination, and a home-like space. Furniture was added to the therapy gym to be more home-like midway through the study. Observations included therapist selection of treatment location and interventions, and observational data of the environment and interactions among therapists and patients. This study found that inpatient rehabilitation environments did influence interventions. The occupational therapists provided therapy in the standard therapy gym environment most often, whether it was enhanced to be more home-like or not, and predominately used preparatory methods.

We evaluated the effects of occupation-based intervention on poststroke upper-extremity (UE) motor recovery, neuroplastic change, and occupational performance in 1 research participant. A 55-yr-old man with chronic stroke and moderately impaired UE motor function participated in 15 sessions of occupation-based intervention in a hospital setting designed to simulate a home environment. We tested behavioral motor function (Fugl-Meyer Assessment, Stroke Impact Scale, Canadian Occupational Performance Measure) and neuroplasticity (transcranial magnetic stimulation [TMS]) at baseline and at completion of intervention. We collected descriptive data on occupational participation throughout the study. All behavioral outcomes indicated clinically relevant improvement. TMS revealed bihemispheric corticomotor reorganization. Descriptive data revealed enhanced occupational performance. Occupation-based intervention delivered in a hospital-based, homelike environment can lead to poststroke neuroplastic change, increased functional use of the affected UE, and improved occupational performance.

The activities of the occupation health physicians also at the Karlsruhe Nuclear Research Center have experienced a change in focus over the past few decades, the causes of which are in the working environment and in work processes. The causes and conditions of diseases at work must be recognized and preventive measures instituted, but there is also need to design the working environment in terms of occupational physiology and industrial hygiene so as to meet human requirements. This includes the use of sociological and psychological concepts and methods in modern occupational medicine. This recognition necessitates the appropriate efforts to be made both in scientific research and in daily medical practive. Modern working life is determined by the joint action of physical and psychological impacts, with more and more importance attaching to psychosensoric impacts. As a result of this development, occupational health physicians spend increasingly more time and effort in medical consulting and on problems in occupational medicine, social medicine, and ergonomics.

Reduction of Endogenous Melatonin Accelerates Cognitive Decline in Mice in a Simulated Occupational Formaldehyde Exposure Environment

2016-02-01

Full Text Available Individuals afflicted with occupational formaldehyde (FA exposure often suffer from abnormal behaviors such as aggression, depression, anxiety, sleep disorders, and in particular, cognitive impairments. Coincidentally, clinical patients with melatonin (MT deficiency also complain of cognitive problems associated with the above mental disorders. Whether and how FA affects endogenous MT metabolism and induces cognitive decline need to be elucidated. To mimic occupational FA exposure environment, 16 healthy adult male mice were exposed to gaseous FA (3 mg/m3 for 7 consecutive days. Results showed that FA exposure impaired spatial memory associated with hippocampal neuronal death. Biochemical analysis revealed that FA exposure elicited an intensive oxidative stress by reducing systemic glutathione levels, in particular, decreasing brain MT concentrations. Inversely, intraperitoneal injection of MT markedly attenuated FA-induced hippocampal neuronal death, restored brain MT levels, and reversed memory decline. At tissue levels, injection of FA into the hippocampus distinctly reduced brain MT concentrations. Furthermore, at cellular and molecular levels, we found that FA directly inactivated MT in vitro and in vivo. These findings suggest that MT supplementation contributes to the rescue of cognitive decline, and may alleviate mental disorders in the occupational FA-exposed human populations.

Energy conservation and the environment: conflict or complement

Energy Technology Data Exchange (ETDEWEB)

Schipper, L.

1978-09-01

The policy discussion following the Oil Embargo was clouded with fears of a return to a primitive existence based on drastically reduced energy inputs to society, or, on the other hand, an abandoning of environmental goals, allegedly a major barrier to development of new energy supplies. Often the energy use associated with environmental improvements was cited as a reason for expanding energy supplies, as if to say that a conflict existed between a clean environment and reductions in energy use. Or it was argued that a relaxation of environmental goals would lower the direct costs of harvesting and using energy and thereby alleviate the need for energy conservation. It has also been argued that the geopolitics of energy alone will force us to substitute riskier or ''dirtier'' energy sources for relatively clean oil and gas. Indeed, there is no question that the relationship among energy, the environment, and economic well-being is complicated. This essay sorts out many of the confusing aspects in order to show how goals relating to the efficient use of energy are aligned both with traditional economic goals and with modern environmental goals. To do this the author analyzes in depth the role of energy in the economy and, using examples, traces the origins of many of the misconceptions about that role--misconceptions that have inhibited a profound discussion of energy-related goals.

The 45th Japanese Society of Occupational and Environmental Allergy (OEA) Annual Meeting 2014 was held in Fukuoka city in conjunction with a technical course for occupational health physicians to learn occupational and environmental diseases more deeply. Allergic reaction due to low concentrations of chemical and biological materials is important in toxicological diseases due to highly concentrated chemical materials in the field of occupational and environmental medicine. In this paper we describe the activities of the OEA, which was established in 1970 and has completely cured patients with severe occupational asthma, such as the regional Konjac asthma in Gunma prefecture and Sea Squirt asthma in Hiroshima prefecture. Regard for the occupational environment will prevent the onset and/or exacerbation of allergic occupational disease in individual employees with allergy. Occupational cancer of the bile duct and asbestosis are also current, serious issues that should be resolved as soon as possible. It is desirable for the occupational health physician to have a large stock of knowledge about toxicological and allergic diseases in various occupational settings to maintain the health and safety of workers.

The roles of the outdoors and occupants in contributing to a potential pan-microbiome of the built environment: a review.

Science.gov (United States)

Leung, Marcus H Y; Lee, Patrick K H

2016-05-24

Recent high-throughput sequencing technology has led to an expansion of knowledge regarding the microbial communities (microbiome) across various built environments (BEs). The microbiome of the BE is dependent upon building factors and conditions that govern how outdoor microbes enter and persist in the BE. Additionally, occupants are crucial in shaping the microbiome of the BE by releasing human-associated microorganisms and resuspending microbes on floors and surfaces. Therefore, both the outdoors and occupants act as major sources of microorganisms found in the BE. However, most characterizations of the microbiome of the BE have been conducted in the Western world. Notably, outdoor locations and population groups present geographical variations in outdoor and human microbiomes, respectively. Given the influences of the outdoor and human microbiomes on BE microbiology, and the geographical variations in outdoor and human microbiomes, it is likely that the microbiomes of BEs also vary by location. The summation of microbiomes between BEs contribute to a potential BE pan-microbiome, which will both consist of microbes that are ubiquitous in indoor environments around the world, and microbes that appear to be endemic to particular geographical locations. Importantly, the BE pan-microbiome can potentially question the global application of our current views on indoor microbiology. In this review, we first provide an assessment on the roles of building and occupant properties on shaping the microbiome of the BE. This is then followed by a description of geographical variations in the microbiomes of the outdoors and humans, the two main sources of microbes in BEs. We present evidence of differences in microbiomes of BEs around the world, demonstrating the existence of a global pan-microbiome of the BE that is larger than the microbiome of any single indoor environment. Finally, we discuss the significance of understanding the BE pan-microbiome and identifying universal

Occupancy of the Invasive Feral Cat Varies with Habitat Complexity.

Directory of Open Access Journals (Sweden)

Rosemary Hohnen

Full Text Available The domestic cat (Felis catus is an invasive exotic in many locations around the world and is thought to be a key factor driving recent mammal declines across northern Australia. Many mammal species native to this region now persist only in areas with high topographic complexity, provided by features such as gorges or escarpments. Do mammals persist in these habitats because cats occupy them less, or despite high cat occupancy? We show that occupancy of feral cats was lower in mammal-rich habitats of high topographic complexity. These results support the idea that predation pressure by feral cats is a factor contributing to the collapse of mammal communities across northern Australia. Managing impacts of feral cats is a global conservation challenge. Conservation actions such as choosing sites for small mammal reintroductions may be more successful if variation in cat occupancy with landscape features is taken into account.

To study the influence of occupational pesticide use on Parkinson's disease (PD) in a population with information on various occupational, residential, and household sources of pesticide exposure. In a population-based case control study in Central California, we used structured interviews to collect occupational history details including pesticide use in jobs, duration of use, product names, and personal protective equipment use from 360 PD cases and 827 controls. We linked reported products to California's pesticide product label database and identified pesticide active ingredients and occupational use by chemical class including fungicides, insecticides, and herbicides. Employing unconditional logistic regression, we estimated odds ratios and 95% confidence intervals for PD and occupational pesticide use. Ever occupational use of carbamates increased risk of PD by 455%, while organophosphorus (OP) and organochlorine (OC) pesticide use doubled risk. PD risk increased 110-211% with ever occupational use of fungicides, herbicides, and insecticides. Using any pesticide occupationally for >10years doubled the risk of PD compared with no occupational pesticide use. Surprisingly, we estimated higher risks among those reporting use of personal protective equipment (PPE). Our findings provide additional evidence that occupational pesticide exposures increase PD risk. This was the case even after controlling for other sources of pesticide exposure. Specifically, risk increased with occupational use of carbamates, OPs, and OCs, as well as of fungicides, herbicides, or insecticides. Interestingly, some types of PPE use may not provide adequate protection during pesticide applications. Copyright © 2017 Elsevier Ltd. All rights reserved.

Civilian law: from occupational medicine to occupational event.

Science.gov (United States)

Mpotos, N; Watelet, J B

Civilian law:from occupational medicine to occupational event. Despite the growing importance of objective measurements, the health effects of many occupational risk factors are currently not fully quantified. Occupational noise, as a widespread risk factor, is illustrative in this regard; there is a strong body of evidence linking it to an important health outcome (hearing loss), but it is less decisively associated with others (such as psychological disorders). It is also distinct from environmental noise, and therefore falls under the responsibility of employers as well as individuals. Noise-induced hearing loss (NIHL) is, at present, incurable and irreversible. However, it is preventable, if effective and global hearing conservation programmes can be implemented. These programmes should not be isolated efforts, but should be integrated into the overall hazard prevention and control programme of the workplace. Belgian law encompasses a set of provisions for prevention and the protection of the health and safety of workers within the workplace, including aspects pertaining to the hygiene of the workplace and psychosocial aspects at work (stress, violence, bullying and sexual harassment, among others). In principle, combating environmental noise is fully addressed in this country. However, other levels of policy-making also play an important role in this regard. For example, the federal government is in charge of product standards, and therefore also of noise emission standards for products. The interpretation and enforcement of Belgian legislation on well-being at work converts European directives and international agreements on well-being at work into Belgian law.

Ecological relationships and processes vary across species’ geographic distributions, life stages and spatial, and temporal scales. Montane landscapes are characterized by low wetland densities, rugged topographies, and cold climates. Consequently, aquatic-dependent and low-vagility ectothermic species (e.g., pool-breeding amphibians) may exhibit unique ecological associations in montane landscapes. We evaluated the relative importance of breeding- and landscape-scale features associated with spotted salamander (Ambystoma maculatum) and wood frog (Lithobates sylvaticus) wetland occupancy in Maine's Upper Montane-Alpine Zone ecoregion, and we determined whether models performed better when the inclusive landscape-scale covariates were estimated with topography-weighted or circular buffers. We surveyed 135 potential breeding sites during May 2013–June 2014 and evaluated environmental relationships with multi-season implicit dynamics occupancy models. Breeding site occupancy by both species was influenced solely by breeding-scale habitat features. Spotted salamander occupancy probabilities increased with previous or current beaver (Castor canadensis) presence, and models generally were better supported when the inclusive landscape-scale covariates were estimated with topography-weighted rather than circular buffers. Wood frog occupancy probabilities increased with site area and percent shallows, but neither buffer type was better supported than the other. Model rank order and support varied between buffer types, but model inferences did not. Our results suggest pool-breeding amphibian conservation in montane Maine include measures to maintain beaver populations and large wetlands with proportionally large areas of shallows ≤1-m deep. Inconsistencies between our study and previous studies substantiate the value of region-specific research for augmenting species’ conservation management plans and suggest the application of out-of-region inferences may promote

Introduction Noise-induced hearing loss (NIHL) is a serious problem for workers and therefore for businesses. The hearing conservation program (HCP) is a set of coordinated measures to prevent the development or evolution of occupational hearing loss, which involves a continuous and dynamic process of implementation of hearing conservation routines through anticipation, recognition, evaluation, and subsequent control of the occurrence of existing environmental risks or of those that may exist in the workplace and lead to workers' hearing damage. Objective The aim of this study was to evaluate the effectiveness of the HCP in preventing further hearing loss in workers with audiograms suggestive of NIHL. The audiometric tests and medical records of 28 furniture company workers exposed to noise were reviewed and monitored for 2 years. Methods This retrospective, cross-sectional study examined five audiometric tests in the medical records (on admission and every semester) of 28 workers in a furniture company (totaling 140 audiometric exams) following the introduction of the HCP. Results Data analysis showed no differences between the audiometric tests conducted on admission and those performed every semester. Conclusions The HCP implemented was effective in preventing the worsening of hearing loss in workers already with NIHL when exposed to occupational noise. Therefore, such a measure could be useful for the employment of workers with hearing loss in job sectors that have noise exposure.

Carbon Oxides Gases for Occupancy Counting and Emergency Control in Fog Environment

Directory of Open Access Journals (Sweden)

Kairong Duan

2018-03-01

Full Text Available The information of human occupancy plays a crucial role in building management. For instance, fewer people, less demand for heat and electricity supply, and vice versa. Moreover, when there is a fire in a building, it is convenient to know how many persons in a single room there are in order to plan a more efficient rescue strategy. However, currently most buildings have not installed adequate devices that can be used to count the number of people, and the most popular embedded fire alarm system triggers a warning only when a fire breaks out with plenty of smoke. In view of this constraint, in this paper we propose a carbon oxides gases based warning system to detect potential fire breakouts and to estimate the number of people in the proximity. In order to validate the efficiency of the devised system, we simulate its application in the Fog Computing environment. Furthermore, we also improve the iFogSim by giving data analytics capacity to it. Based on this framework, energy consumption, latency, and network usage of the designed system obtained from iFogSim are compared with those obtained from Cloud environment.

Occupational therapy practice in emergency care: Occupational therapists' perspectives.

Spang, Lisa; Holmqvist, Kajsa

2015-01-01

Emergency care takes place in a complex work environment that is characterized by critically ill patients, short hospital stays, and a wide variety of different healthcare professionals. Studies of occupational therapists' (OTs) experiences of working within emergency care have shown that they often experience difficulties in explaining the essence of occupational therapy and have to justify their approaches. Much effort has been made in Sweden to help OTs dispel the notion that occupational therapy is difficult to explain, and the aim of this study was to describe how Swedish OTs perceive their work in emergency care. A qualitative descriptive approach was taken, and 14 interviews were conducted with OTs working in emergency care. Qualitative content analysis was used to analyse the data. The overall theme that emerged was "Feeling established through deliberate occupation-based work". The underlying categories showed different strategies used by the OTs to provide occupational therapy in an emergency care context. Deliberate strategies were used to demonstrate the effectiveness of occupational therapy and its approaches to patients and other health care professionals, and this resulted in the OTs feeling both established and needed. Unlike the OTs in previous studies, the Swedish OTs experienced no difficulties in explaining occupational therapy and could make convincing arguments for their interventions. Parallel to their clinical work, the OTs worked with on-going development to find ways to improve their approaches. In summary, these Swedish OTs seem to have been provided with a professional language and the knowledge required to establish themselves in an emergency care setting.

INTRODUCTION. The relationship between stressful events in the workplace and their effect on health is the subject of numerous studies where the phenomenon of"Mobbing" has become of increasing interest in Social Psychiatry and Occupational Medicine. The aim of this study is to evaluate the relationship between mobbing, occupational stress and personality structure in a group of persons who consulted the "Work Adaptation Disorders Centre" at the Institute of Occupational Medicine between December 2008 and June 2010 for mobbing-related issues. Referring to Leymann Inventory of Psychological Terrorization (LIPT), H. Ege, Occupational Stress Indicator (OSI), Minnesota Multiphasic Personality Inventory 2 (MMPI-2), it has been possible to assess situations of harassment, the sources and the effects of work stress, as well as personality traits in the study group. The results showed that high levels of occupational stress and inadequate coping strategies can lead to depressive, hysterical and paranoid manifestations. Although the relationship between mobbing, occupational stress and personality traits still remains controversial, there is an association between perception of adverse behaviour and mental health, regardless of the subject's ability to cope with stressful life events. The data seem to confirm that the prevention of bullying must be implemented by the work organization and by handling interpersonal conflicts in the work context.

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

Big biology meets microclimatology: defining thermal niches of ectotherms at landscape scales for conservation planning.

Temperature profoundly affects ecology, a fact ever more evident as the ability to measure thermal environments increases and global changes alter these environments. The spatial structure of thermalscapes is especially relevant to the distribution and abundance of ectothermic organisms, but the ability to describe biothermal relationships at extents and grains relevant to conservation planning has been limited by small or sparse data sets. Here, we combine a large occurrence database of >23 000 aquatic species surveys with stream microclimate scenarios supported by an equally large temperature database for a 149 000-km mountain stream network to describe thermal relationships for 14 fish and amphibian species. Species occurrence probabilities peaked across a wide range of temperatures (7.0-18.8°C) but distinct warm- or cold-edge distribution boundaries were apparent for all species and represented environments where populations may be most sensitive to thermal changes. Warm-edge boundary temperatures for a native species of conservation concern were used with geospatial data sets and a habitat occupancy model to highlight subsets of the network where conservation measures could benefit local populations by maintaining cool temperatures. Linking that strategic approach to local estimates of habitat impairment remains a key challenge but is also an opportunity to build relationships and develop synergies between the research, management, and regulatory communities. As with any data mining or species distribution modeling exercise, care is required in analysis and interpretation of results, but the use of large biological data sets with accurate microclimate scenarios can provide valuable information about the thermal ecology of many ectotherms and a spatially explicit way of guiding conservation investments. © 2017 by the Ecological Society of America.

Landscape capability models as a tool to predict fine-scale forest bird occupancy and abundance

ContextSpecies-specific models of landscape capability (LC) can inform landscape conservation design. Landscape capability is “the ability of the landscape to provide the environment […] and the local resources […] needed for survival and reproduction […] in sufficient quantity, quality and accessibility to meet the life history requirements of individuals and local populations.” Landscape capability incorporates species’ life histories, ecologies, and distributions to model habitat for current and future landscapes and climates as a proactive strategy for conservation planning.ObjectivesWe tested the ability of a set of LC models to explain variation in point occupancy and abundance for seven bird species representative of spruce-fir, mixed conifer-hardwood, and riparian and wooded wetland macrohabitats.MethodsWe compiled point count data sets used for biological inventory, species monitoring, and field studies across the northeastern United States to create an independent validation data set. Our validation explicitly accounted for underestimation in validation data using joint distance and time removal sampling.ResultsBlackpoll warbler (Setophaga striata), wood thrush (Hylocichla mustelina), and Louisiana (Parkesia motacilla) and northern waterthrush (P. noveboracensis) models were validated as predicting variation in abundance, although this varied from not biologically meaningful (1%) to strongly meaningful (59%). We verified all seven species models [including ovenbird (Seiurus aurocapilla), blackburnian (Setophaga fusca) and cerulean warbler (Setophaga cerulea)], as all were positively related to occupancy data.ConclusionsLC models represent a useful tool for conservation planning owing to their predictive ability over a regional extent. As improved remote-sensed data become available, LC layers are updated, which will improve predictions.

Mechanistic species distribution modelling as a link between physiology and conservation.

Science.gov (United States)

Evans, Tyler G; Diamond, Sarah E; Kelly, Morgan W

2015-01-01

Climate change conservation planning relies heavily on correlative species distribution models that estimate future areas of occupancy based on environmental conditions encountered in present-day ranges. The approach benefits from rapid assessment of vulnerability over a large number of organisms, but can have poor predictive power when transposed to novel environments and reveals little in the way of causal mechanisms that define changes in species distribution or abundance. Having conservation planning rely largely on this single approach also increases the risk of policy failure. Mechanistic models that are parameterized with physiological information are expected to be more robust when extrapolating distributions to future environmental conditions and can identify physiological processes that set range boundaries. Implementation of mechanistic species distribution models requires knowledge of how environmental change influences physiological performance, and because this information is currently restricted to a comparatively small number of well-studied organisms, use of mechanistic modelling in the context of climate change conservation is limited. In this review, we propose that the need to develop mechanistic models that incorporate physiological data presents an opportunity for physiologists to contribute more directly to climate change conservation and advance the field of conservation physiology. We begin by describing the prevalence of species distribution modelling in climate change conservation, highlighting the benefits and drawbacks of both mechanistic and correlative approaches. Next, we emphasize the need to expand mechanistic models and discuss potential metrics of physiological performance suitable for integration into mechanistic models. We conclude by summarizing other factors, such as the need to consider demography, limiting broader application of mechanistic models in climate change conservation. Ideally, modellers, physiologists and

Full Text Available The Navalmaíllo site is a karstic rockshelter located in a mountain environment near the Lozoya river. The location of the site allows for the close monitoring of the surrounding area, for following the migrations of animals and for the temporary residence of human groups. The difficulties associated with estimating the time span of occupational processes at archaeological sites raise the problem of the synchrony and diachrony of occupations that form palimpsests. Archaeostratigraphy has revealed the integrity of the sedimentary deposit, how it has been affected by both natural agents (falling boulders and the conservation of the site and human agents (the excavation method. The deformation of the plastic deposit is reflected in the archaeostratigraphy, but the two periods of occupation identified have been preserved and were not largely affected. The archaeostratigraphic approach has resulted in the identification of some of the taphosedimentary aspects of Layer F and in the deciphering of the cultural palimpsest, establishing the cultural sequence of occupations at the Navalmaíllo site.

An analysis of heating and cooling conservation features in commercial buildings

International Nuclear Information System (INIS)

Sutherland, R.J.

1990-01-01

One purpose of this study is to estimate the relationship in commercial buildings between conservation investments, fuel prices, building occupancy and building characteristics for new buildings and for existing buildings. The data base is a nationwide survey of energy in commercial buildings conducted by the Energy Information Administration (EIA) in 1986. Some simple cross-tabulations indicate that conservation measures vary with building size, building age, type of building, and fuel used for building heating. Regression estimates of a conservation model indicate that the number of conservation features installed during construction is a positive function of the price of the heating fuel at the time of construction. Subsequent additions of conservation features are positively correlated with increases in heating fuel prices. Given the EIA projection of relatively stable future energy prices, the number of retrofits may not increase significantly. Also, energy efficiency in new buildings may not continue to increase relative to current new buildings. If fuel prices affect consumption via initial conservation investments, current fuel prices, marginal or average, are not the appropriate specification. The fuel price regression results indicate that conservation investments in new buildings are responsive to market signals. Retrofits are less responsive to market signals. The number of conservation features in a building is not statistically related to the type of occupancy (owner versus renter), which implies that conservation strategies are not impeded by the renting or leasing of buildings

Acute ankle sprain: conservative or surgical approach?

Al-Mohrej, Omar A.; Al-Kenani, Nader S.

2016-01-01

Ankle sprains fall into two main categories: acute ankle sprains and chronic ankle instability, which are among the most common recurrent injuries during occupational activities, athletic events, training and army service. Acute ankle sprain is usually managed conservatively and functional rehabilitation failure by conservative treatment leads to development of chronic ankle instability, which most often requires surgical intervention. Enhancing the in-depth knowledge of the ankle anatomy, biomechanics and pathology helps greatly in deciding the management options. Cite this article: Al-Mohrej OA, Al-Kenani NS.

Airborne spread of expiratory droplet nuclei between the occupants of indoor environments: A review.

Science.gov (United States)

Ai, Z T; Melikov, A K

2018-07-01

This article reviews past studies of airborne transmission between occupants in indoor environments, focusing on the spread of expiratory droplet nuclei from mouth/nose to mouth/nose for non-specific diseases. Special attention is paid to summarizing what is known about the influential factors, the inappropriate simplifications of the thermofluid boundary conditions of thermal manikins, the challenges facing the available experimental techniques, and the limitations of available evaluation methods. Secondary issues are highlighted, and some new ways to improve our understanding of airborne transmission indoors are provided. The characteristics of airborne spread of expiratory droplet nuclei between occupants, which are influenced correlatively by both environmental and personal factors, were widely revealed under steady-state conditions. Owing to the different boundary conditions used, some inconsistent findings on specific influential factors have been published. The available instrumentation was too slow to provide accurate concentration profiles for time-dependent evaluations of events with obvious time characteristics, while computational fluid dynamics (CFD) studies were mainly performed in the framework of inherently steady Reynolds-averaged Navier-Stokes modeling. Future research needs in 3 areas are identified: the importance of the direction of indoor airflow patterns, the dynamics of airborne transmission, and the application of CFD simulations. © 2018 John Wiley & Sons A/S.

Coupled force-balance and particle-occupation rate equations for high-field electron transport

International Nuclear Information System (INIS)

Lei, X. L.

2008-01-01

It is pointed out that in the framework of balance-equation approach, the coupled force-balance and particle-occupation rate equations can be used as a complete set of equations to determine the high-field transport of semiconductors in both strong and weak electron-electron interaction limits. We call to attention that the occupation rate equation conserves the total particle number and maintains the energy balance of the relative electron system, and there is no need to introduce any other term in it. The addition of an energy-drift term in the particle-occupation rate equation [Phys. Rev. B 71, 195205 (2005)] is physically inadequate for the violation of the total particle-number conservation and the energy balance. It may lead to a substantial unphysical increase of the total particle number by the application of a dc electric field

Rapid expansion and intensification of agriculture create challenges for the conservation of biodiversity and associated ecosystem services. In Argentina, the total row crop planted area has increased in recent decades with the expansion of soybean cultivation, homogenizing the landscape. In 2003 we started the first long-term, large-scale bird monitoring program in agroecosystems of central Argentina, in portions of the Pampas and Espinal ecoregions. Using data from this program, we evaluated the effect of land use and cover extent on birds between 2003-2012, accounting for imperfect detection probabilities using a Bayesian hierarchical, multi-species and multi-season occupancy model. We tested predictions that species diversity is positively related to habitat heterogeneity, which in intensified agroecosystems is thought to be mediated by food availability; thus the extent of land use and cover is predicted to affect foraging guilds differently. We also infer about ecosystem services provisioning and inform management recommendations for conservation of birds. Overall our results support the predictions. Although many species within each guild responded differently to land use and native forest cover, we identified generalities for most trophic guilds. For example, granivorous gleaners, ground insectivores and omnivores responded negatively to high proportions of soybean, while insectivore gleaners and aerial foragers seemed more tolerant. Habitat heterogeneity would likely benefit most species in an intensified agroecosystem, and can be achieved with a diversity of crops, pastures, and natural areas within the landscape. Although most studied species are insectivores, potentially beneficial for pest control, some guilds such as ground insectivores are poorly represented, suggesting that agricultural intensification reduces ecological functions, which may be recovered through management. Continuation of the bird monitoring program will allow us to continue to

Although many species within each guild responded differently to land use and native forest cover, we identified generalities for most trophic guilds. For example, granivorous gleaners, ground insectivores and omnivores responded negatively to high proportions of soybean, while insectivore gleaners and aerial foragers seemed more tolerant. Habitat heterogeneity would likely benefit most species in an intensified agroecosystem, and can be achieved with a diversity of crops, pastures, and natural areas within the landscape. Although most studied species are insectivores, potentially beneficial for pest control, some guilds such as ground insectivores are poorly represented, suggesting that agricultural intensification reduces ecological functions, which may be recovered through management. Continuation of the bird monitoring program will allow

Occupational exposure limits have traditionally focused on preventing morbidity and mortality arising from inhalation exposures to individual chemical stressors in the workplace. While central to occupational risk assessment, occupational exposure limits have limited application as a refined disease prevention tool because they do not account for all of the complexities of the work and non-occupational environments and are based on varying health endpoints. To be of greater utility, occupational exposure limits and other risk management tools could integrate broader consideration of risks from multiple exposure pathways and routes (aggregate risk) as well as the combined risk from exposure to both chemical and non-chemical stressors, within and beyond the workplace, including the possibility that such exposures may cause interactions or modify the toxic effects observed (cumulative risk). Although still at a rudimentary stage in many cases, a variety of methods and tools have been developed or are being used in allied risk assessment fields to incorporate such considerations in the risk assessment process. These approaches, which are collectively referred to as cumulative risk assessment, have potential to be adapted or modified for occupational scenarios and provide a tangible path forward for occupational risk assessment. Accounting for complex exposures in the workplace and the broader risks faced by the individual also requires a more complete consideration of the composite effects of occupational and non-occupational risk factors to fully assess and manage worker health problems. Barriers to integrating these different factors remain, but new and ongoing community-based and worker health-related initiatives may provide mechanisms for identifying and integrating risk from aggregate exposures and cumulative risks from all relevant sources, be they occupational or non-occupational.

Persons experiencing or at risk of homelessness have occupational needs that are seldom addressed in the Canadian system of care. The lack of documented evidence on occupational therapy practices in this field hinders the development of the profession. This article identifies current and potential practices that aim to enable or support the occupations of persons experiencing or at risk of homelessness. A scoping review was conducted, including evidence from both occupational therapy and non-occupational therapy sources. One hundred and seventy-eight papers were selected in the areas of occupational performance skills training, enrichment of occupational repertoire, employment/education, physical rehabilitation services, child/family services, community building, occupational transition from homeless to housed, literacy, and disaster relief. Occupational therapists can build environments and create opportunities that facilitate occupational engagement of individuals experiencing homelessness. Gaps in knowledge include the evaluation of occupational therapy practices, the Canadian context of family homelessness, and the cultural safety of occupational therapy interventions.

This paper focuses on the occupational experiences of five men living within a forensic mental health unit over a year. This study used a descriptive qualitative case study methodology to explore the meaning and value placed on daily life (activities, occupations and routines), and how this changed over time. The men's stories showed a complex picture of their experiences of daily life. This study demonstrated the impact of the environment on the men and the ongoing challenge of the need to balance treatment/therapy with security demands and opportunities. Three interrelated themes were identified: (1) Power and Occupation; (2) Therapy or Punishment; (3) Occupational Opportunities within Restrictions. These findings serve as a reminder to clinical teams to reassess the value of occupations attributed by their patients and the impact of the secure environment, whilst also acknowledging the potential for occupations to have a negative impact on well-being.

A two-phase sampling design for increasing detections of rare species in occupancy surveys

1. Occupancy estimation is a commonly used tool in ecological studies owing to the ease at which data can be collected and the large spatial extent that can be covered. One major obstacle to using an occupancy-based approach is the complications associated with designing and implementing an efficient survey. These logistical challenges become magnified when working with rare species when effort can be wasted in areas with none or very few individuals. 2. Here, we develop a two-phase sampling approach that mitigates these problems by using a design that places more effort in areas with higher predicted probability of occurrence. We compare our new sampling design to traditional single-season occupancy estimation under a range of conditions and population characteristics. We develop an intuitive measure of predictive error to compare the two approaches and use simulations to assess the relative accuracy of each approach. 3. Our two-phase approach exhibited lower predictive error rates compared to the traditional single-season approach in highly spatially correlated environments. The difference was greatest when detection probability was high (0·75) regardless of the habitat or sample size. When the true occupancy rate was below 0·4 (0·05-0·4), we found that allocating 25% of the sample to the first phase resulted in the lowest error rates. 4. In the majority of scenarios, the two-phase approach showed lower error rates compared to the traditional single-season approach suggesting our new approach is fairly robust to a broad range of conditions and design factors and merits use under a wide variety of settings. 5. Synthesis and applications. Conservation and management of rare species are a challenging task facing natural resource managers. It is critical for studies involving rare species to efficiently allocate effort and resources as they are usually of a finite nature. We believe our approach provides a framework for optimal allocation of effort while

Conservation endocrinology

Endocrinologists can make significant contributions to conservation biology by helping to understand the mechanisms by which organisms cope with changing environments. Field endocrine techniques have advanced rapidly in recent years and can provide substantial information on the growth, stress, and reproductive status of individual animals, thereby providing insight into current and future responses of populations to changes in the environment. Environmental stressors and reproductive status can be detected nonlethally by measuring a number of endocrine-related endpoints, including steroids in plasma, living and nonliving tissue, urine, and feces. Information on the environmental or endocrine requirements of individual species for normal growth, development, and reproduction will provide critical information for species and ecosystem conservation. For many taxa, basic information on endocrinology is lacking, and advances in conservation endocrinology will require approaches that are both “basic” and “applied” and include integration of laboratory and field approaches.

Modeling the Qualitative Relationship among Risks Associated with Occupational and Workplace Hazards in Seaport Environments: the Case of Apapa Port, Nigeria

2017-01-01

Full Text Available The aim of the research is to establish the quantitative relationship and impacts of risks associated with various categories of occupational and workplace hazards in the Nigerian seaports. It was carried out by obtaining time series statistical data of 7 years from hazard identification and risk assessment report of Nigerian Ports Authority (NPA Apapa, western port headquarters. The variables considered are the associated risks of various types of occupational and workplace hazards to which seaport workers were exposed from 2009-2014. The overall level of associated risks of occupational and workplace hazards represent the cumulative of various hazards and were treated as the dependent variable ‘Y’. The exposures to the risks of mechanical hazards, ergonomic hazards, physical hazards, noise/environmental hazards were symbolized as X1, X2, X3, and X4 respectively and treated as independent variables. The method of multiple regression analysis was used to analyze the time series data. T-test was used to test the hypotheses. It was found that risks associated to mechanical hazard, ergonomic hazards, noise/vibration hazard, physical hazards, all have significant impact on the overall level of risk of exposure to occupational and workplace hazards in Nigerian seaport environment. It was recommended that proactive investment in safety inspective and management system is needed to limit the level of exposure of seaport staff to occupational hazards.

Perspectives that individualize occupation are poorly aligned with socially responsive and transformative occupation-focused research, education, and practice. Their predominant use in occupational therapy risks the perpetuation, rather than resolution, of occupational inequities. In this paper, we problematize taken-for-granted individualistic analyses of occupation and illustrate how critical theoretical perspectives can reveal the ways in which structural factors beyond an individual's immediate control and environment shape occupational possibilities and occupational engagement. Using a critically reflexive approach, we draw on three distinct qualitative research studies to examine the potential of critical theorizing for expanding beyond a reliance on individualistic analyses and practices. Our studies highlight the importance of addressing the socio-historical and political contexts of occupation and demonstrate the contribution of critical perspectives to socially responsive occupational therapy. In expanding beyond individualistic analyses of occupation, critical perspectives advance research and practices towards addressing socio-political mediators of occupational engagement and equity.

Management decision making for fisher populations informed by occupancy modeling

Harvest data are often used by wildlife managers when setting harvest regulations for species because the data are regularly collected and do not require implementation of logistically and financially challenging studies to obtain the data. However, when harvest data are not available because an area had not previously supported a harvest season, alternative approaches are required to help inform management decision making. When distribution or density data are required across large areas, occupancy modeling is a useful approach, and under certain conditions, can be used as a surrogate for density. We collaborated with the New York State Department of Environmental Conservation (NYSDEC) to conduct a camera trapping study across a 70,096-km2 region of southern New York in areas that were currently open to fisher (Pekania [Martes] pennanti) harvest and those that had been closed to harvest for approximately 65 years. We used detection–nondetection data at 826 sites to model occupancy as a function of site-level landscape characteristics while accounting for sampling variation. Fisher occupancy was influenced positively by the proportion of conifer and mixed-wood forest within a 15-km2 grid cell and negatively associated with road density and the proportion of agriculture. Model-averaged predictions indicated high occupancy probabilities (>0.90) when road densities were low (0.50). Predicted occupancy ranged 0.41–0.67 in wildlife management units (WMUs) currently open to trapping, which could be used to guide a minimum occupancy threshold for opening new areas to trapping seasons. There were 5 WMUs that had been closed to trapping but had an average predicted occupancy of 0.52 (0.07 SE), and above the threshold of 0.41. These areas are currently under consideration by NYSDEC for opening a conservative harvest season. We demonstrate the use of occupancy modeling as an aid to management decision making when harvest-related data are unavailable and when budgetary

There is increasing evidence that obesity and overweight may be related, in part, to adverse work conditions. In particular, the risk of obesity may increase in high-demand, low-control work environments, and for those who work long hours. In addition, obesity may modify the risk for vibration-induced injury and certain occupational musculoskeletal disorders. We hypothesized that obesity may also be a co-risk factor for the development of occupational asthma and cardiovascular disease that and it may modify the worker's response to occupational stress, immune response to chemical exposures, and risk of disease from occupational neurotoxins. We developed 5 conceptual models of the interrelationship of work, obesity, and occupational safety and health and highlighted the ethical, legal, and social issues related to fuller consideration of obesity's role in occupational health and safety.

The American Occupational Therapy Association (AOTA) has challenged occupational therapy practitioners to advance the profession so that we may become more "powerful" and "widely recognized" by the year 2017 (AOTA, 2007a). To fully achieve this vision, this article argues that the profession should encourage occupational therapy entrepreneurship. As Herz, Bondoc, Richmond, Richman, and Kroll (2005, p.2) stated, "Entrepreneurship may provide us with the means to achieve the outcomes we need to succeed in the current health care environment." This article also argues the urgency of seizing the many opportunities that entrepreneurship offers and recommends specific actions to be taken by AOTA and by therapists.

FastSLAM Using Compressed Occupancy Grids

Directory of Open Access Journals (Sweden)

Christopher Cain

2016-01-01

Full Text Available Robotic vehicles working in unknown environments require the ability to determine their location while learning about obstacles located around them. In this paper a method of solving the SLAM problem that makes use of compressed occupancy grids is presented. The presented approach is an extension of the FastSLAM algorithm which stores a compressed form of the occupancy grid to reduce the amount of memory required to store the set of occupancy grids maintained by the particle filter. The performance of the algorithm is presented using experimental results obtained using a small inexpensive ground vehicle equipped with LiDAR, compass, and downward facing camera that provides the vehicle with visual odometry measurements. The presented results demonstrate that although with our approach the occupancy grid maintained by each particle uses only 40% of the data needed to store the uncompressed occupancy grid, we can still achieve almost identical results to the approach where each particle filter stores the full occupancy grid.

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

Indoor nonindustrial work environments were designated a priority research area through the nationwide stakeholder process that created the National Occupational Research Agenda. A multidisciplinary research team used member consensus and quantitative estimates, with extensive external review, to develop a specific research agenda. The team outlined the following priority research topics: building-influenced communicable respiratory infections, building-related asthma/allergic diseases, and nonspecific building-related symptoms; indoor environmental science; and methods for increasing implementation of healthful building practices. Available data suggest that improving building environments may result in health benefits for more than 15 million of the 89 million US indoor workers, with estimated economic benefits of $5 to $75 billion annually. Research on these topics, requiring new collaborations and resources, offers enormous potential health and economic returns. PMID:12197969

Enabling occupation at the end of life: A literature review.

Science.gov (United States)

Mills, Katherine; Payne, Angela

2015-12-01

Occupation, or meaningful activity, can contribute to the well-being and quality of life of all individuals. It is thus a logical tautology that occupation should be enabled for those at the end of life. Our present review examines current provision of these processes by Occupational Therapist, who can be much-valued members of multidisciplinary palliative care teams. Following a literature search and critical selection, 10 global papers were identified examining occupation and occupational therapy at the end of life in the acute, hospice, and community environments. Universally, there appeared to be a dearth of therapists working in end-of-life care. Provision of palliative care in hospitals was found to be compensatory or rehabilitative. Hospice therapy emerged as pleasingly occupational, though the number of hospice places was disappointingly few. Community literature was sparse, so it proved challenging to draw definitive conclusions. Promising research refracted light on occupation at home; however, it also revealed stretched domiciliary services, where clients are not well informed about the potential scope of occupational therapy. A "good death" involving a quality end-of-life experience is the foundational goal overarching all therapy and medicine in the provision of palliative care. Arguably, an occupation-focused approach provided by therapists meets client needs to enable meaningful experiences in the limited time left to them. Current occupational therapy practice environments are not necessarily achieving these goals in commensurate fashion. There is a need to promote the role of occupational therapy and circumscribe what therapists can offer. Further research is necessitated across all environments and future funding for therapist positions in palliative teams. End-of-life care can be complex and challenging; however, therapists can facilitate fulfillment of client-centered occupational goals. In engaging with personally constructed nuances of meaning

Seasonal differences in extinction and colonization drive occupancy dynamics of an imperilled amphibian.

Full Text Available A detailed understanding of the population dynamics of many amphibian species is lacking despite concerns about declining amphibian biodiversity and abundance. This paper explores temporal patterns of occupancy and underlying extinction and colonization dynamics in a regionally imperiled amphibian species, the Northern leopard frog (Lithobates pipiens in Alberta. Our study contributes to elucidating regional occupancy dynamics at northern latitudes, where climate extremes likely have a profound effect on seasonal occupancy. The primary advantage of our study is its wide geographic scale (60,000 km2 and the use of repeat visual surveys each spring and summer from 2009-2013. We find that occupancy varied more dramatically between seasons than years, with low spring and higher summer occupancy. Between spring and summer, colonization was high and extinction low; inversely, colonization was low and extinction high over the winter. The dynamics of extinction and colonization are complex, making conservation management challenging. Our results reveal that Northern leopard frog occupancy was constant over the last five years and thus there is no evidence of decline or recovery within our study area. Changes to equilibrium occupancy are most sensitive to increasing colonization in the spring or declining extinction in the summer. Therefore, conservation and management efforts should target actions that are likely to increase spring colonization; this could be achieved through translocations or improving the quality or access to breeding habitat. Because summer occupancy is already high, it may be difficult to improve further. Nevertheless, summer extinction could be reduced by predator control, increasing water quality or hydroperiod of wetlands, or increasing the quality or quantity of summer habitat.

Salamander occupancy in headwater stream networks

1. Stream ecosystems exhibit a highly consistent dendritic geometry in which linear habitat units intersect to create a hierarchical network of connected branches. 2. Ecological and life history traits of species living in streams, such as the potential for overland movement, may interact with this architecture to shape patterns of occupancy and response to disturbance. Specifically, large-scale habitat alteration that fragments stream networks and reduces connectivity may reduce the probability a stream is occupied by sensitive species, such as stream salamanders. 3. We collected habitat occupancy data on four species of stream salamanders in first-order (i.e. headwater) streams in undeveloped and urbanised regions of the eastern U.S.A. We then used an information-theoretic approach to test alternative models of salamander occupancy based on a priori predictions of the effects of network configuration, region and salamander life history. 4. Across all four species, we found that streams connected to other first-order streams had higher occupancy than those flowing directly into larger streams and rivers. For three of the four species, occupancy was lower in the urbanised region than in the undeveloped region. 5. These results demonstrate that the spatial configuration of stream networks within protected areas affects the occurrences of stream salamander species. We strongly encourage preservation of network connections between first-order streams in conservation planning and management decisions that may affect stream species.

Zoonoses as occupational diseases

2008-12-01

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

Dedicated Filter for Robust Occupancy Grid Mapping

2015-03-01

Full Text Available Sensor based perception of the environment is an emerging area of the mobile robot research where sensors play a pivotal role. For autonomous mobile robots, the fundamental requirement is the convergent of the range information in to high level internal representation. Internal representation in the form of occupancy grid is commonly used in autonomous mobile robots due to its various advantages. There are several sensors such as vision sensor, laser rage finder, and ultrasonic and infrared sensors etc. play roles in mapping. However the sensor information failure, sensor inaccuracies, noise, and slow response are the major causes of an error in the mapping. To improve the reliability of the mobile robot mapping multisensory data fusion is considered as an optimal solution. This paper presents a novel architecture of sensor fusion frame work in which a dedicated filter (DF is proposed to increase the robustness of the occupancy grid for indoor environment. The technique has been experimentally verified for different indoor test environments. The proposed configuration shows improvement in the occupancy grid with the implementation of dedicated filters.

Conservation significance of alternative nests of golden eagles

Directory of Open Access Journals (Sweden)

Brian A. Millsap

2015-01-01

Full Text Available Golden eagles (Aquila chrysaetos are long-lived raptors that maintain nesting territories that may be occupied for a century or longer. Within occupied nesting territories there is one nest in which eagles lay their eggs in a given year (i.e., the used nest, but there are usually other nests (i.e., alternative nests. Conservation plans often protect used nests, but not alternative nests or nesting territories that appear vacant. Our objective is to review literature on golden eagle use of alternative nests and occupancy of nesting territories to determine if alternative nests are biologically significant and warrant greater conservation consideration. Our review shows that: (1 alternative nests or their associated habitat are most often in core areas of golden eagle nesting territories; (2 alternative nests likely will become used in the future; (3 probability of an alternative nest becoming used is greatest where prey availability is high and alternative nest sites are limited; (4 likelihood of annual occupancy or reoccupancy of golden eagle nesting territories is high; and (5 prey availability is the most important determinant of nesting territory occupancy and breeding activity. We recommend alternative nests be treated with the same deference as used nests in land use planning.

Predicting patch occupancy in fragmented landscapes at the rangewide scale for an endangered species: an example of an American warbler

KAUST Repository

Collier, Bret A.

2011-08-25

AIM: Our objective was to identify the distribution of the endangered golden-cheeked warbler (Setophaga chrysoparia) in fragmented oak-juniper woodlands by applying a geoadditive semiparametric occupancy model to better assist decision-makers in identifying suitable habitat across the species breeding range on which conservation or mitigation activities can be focused and thus prioritize management and conservation planning. LOCATION: Texas, USA. METHODS: We used repeated double-observer detection/non-detection surveys of randomly selected (n = 287) patches of potential habitat to evaluate warbler patch-scale presence across the species breeding range. We used a geoadditive semiparametric occupancy model with remotely sensed habitat metrics (patch size and landscape composition) to predict patch-scale occupancy of golden-cheeked warblers in the fragmented oak-juniper woodlands of central Texas, USA. RESULTS: Our spatially explicit model indicated that golden-cheeked warbler patch occupancy declined from south to north within the breeding range concomitant with reductions in the availability of large habitat patches. We found that 59% of woodland patches, primarily in the northern and central portions of the warbler\\'s range, were predicted to have occupancy probabilities ≤0.10 with only 3% of patches predicted to have occupancy probabilities >0.90. Our model exhibited high prediction accuracy (area under curve = 0.91) when validated using independently collected warbler occurrence data. MAIN CONCLUSIONS: We have identified a distinct spatial occurrence gradient for golden-cheeked warblers as well as a relationship between two measurable landscape characteristics. Because habitat-occupancy relationships were key drivers of our model, our results can be used to identify potential areas where conservation actions supporting habitat mitigation can occur and identify areas where conservation of future potential habitat is possible. Additionally, our results can be

Viral hepatitis as an occupational disease in Poland.

Bilski, Bartosz

2011-07-01

In medical terms, occupational diseases are defined as health disorders specifically associated with the working environment of people and their occupational activity. From the medical and legal perspectives, the vast majority of European countries consider particular diseases to be of occupational origin if they are mentioned in the current list of occupational diseases and caused by exposure to factors in the working environment that are harmful to health. The aim of this study was to analyze the occurrence of cases of viral hepatitis certified as an occupational disease in Poland during 1979-2009. This article presents the medical, economic, and legal aspects of the epidemiology of hepatitis as an occupational disease in Poland. Publically available statistical data on certified occupational diseases in Poland and data contained in individual "occupational disease diagnosis cards" (based on data used in Poland statistical form), regarding certified cases of hepatitis among health care professionals, which were collected by the Department of Occupational Hygiene of the Polish Public Health Service, were analyzed in this study. In Poland, the highest number of cases of hepatitis certified as an occupational disease was observed in 1987. A gradual reduction in the number of cases of hepatitis as an occupational disease has been noted since then. Currently, hepatitis C as an occupational disease is certified more frequently than hepatitis B. In Poland, the number of women with hepatitis certified as an occupational disease is higher than that of men. However, among health care professionals, particularly nurses, this difference is insignificant because women outnumber the men. The existence of such a situation is due to the significant quantitative predominance of women over men among medical personnel, especially among nurses. Immunization of health care professionals against the hepatitis B virus (HBV), introduced in Poland in 1988, was an important factor

Full Text Available Abstract Marine and freshwater scientists are potentially exposed to a wide variety of occupational hazards. Depending on the focus of their research, risks may include animal attacks, physiological stresses, exposure to toxins and carcinogens, and dangerous environmental conditions. Many of these hazards have been investigated amongst the general population in their recreational use of the environment; however, very few studies have specifically related potential hazards to occupational exposure. For example, while the incidence of shark and crocodile attacks may invoke strong emotions and the occupational risk of working with these animals is certainly real, many more people are stung by jellyfish or bitten by snakes or dogs each year. Furthermore, a large proportion of SCUBA-related injuries and deaths are incurred by novice or uncertified divers, rather than professional divers using aquatic environments. Nonetheless, marine and freshwater research remains a potentially risky occupation, and the likelihood of death, injury and long-term health impacts still needs to be seriously considered.

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

Occupancy modeling of autonomously recorded vocalizations to predict distribution of rallids in tidal wetlands

Conservation and management for a species requires reliable information on its status, distribution, and habitat use. We identified occupancy and distributions of king (Rallus elegans) and clapper (R. crepitans) rail populations in marsh complexes along the Pamunkey and Mattaponi Rivers in Virginia, USA by modeling data on vocalizations recorded from autonomous recording units (ARUs). Occupancy probability for both species combined was 0.64 (95% CI: 0.53, 0.75) in marshes along the Pamunkey and 0.59 (0.45, 0.72) in marshes along the Mattaponi. Occupancy probability along the Pamunkey was strongly influenced by salinity, increasing logistically by a factor of 1.62 (0.6, 2.65) per parts per thousand of salinity. In contrast, there was not a strong salinity gradient on the Mattaponi and therefore vegetative community structure determined occupancy probability on that river. Estimated detection probability across both marshes was 0.63 (0.62, 0.65), but detection rates decreased as the season progressed. Monitoring wildlife within wetlands presents unique challenges for conservation managers. Our findings provide insight not only into how rails responded to environmental variation but also into the general utility of ARUs for occupancy modeling of the distribution and habitat associations of rails within tidal marsh systems.

[OCCUPATIONAL HEALTH RISK ASSESSMENT AND MANAGEMENT IN WORKERS IN IMPROVEMENT OF NATIONAL POLICY IN OCCUPATIONAL HYGIENE AND SAFETY].

In accordance with the international documents in the field of occupational safety and hygiene, the assessment and minimization of occupational risks is a key instrument for the health maintenance of workers. One of the main ways to achieve it is the minimization of occupational risks. Correspondingly, the instrument for the implementation of this method is the methodology of analysis of occupational risks. In Russian Federation there were the preconditions for the formation of the system for the assessment and management of occupational risks. As the target of the national (state) policy in the field of occupational safety in accordance with ILO Conventions it can be offered the prevention of accidents and injuries to health arising from work or related with it, minimizing the causes of hazards inherent in the working environment, as far as it is reasonably and practically feasible. Global trend ofusing the methodology of the assessment and management of occupational risks to life and health of citizens requires the improvement of national policies in the field of occupational hygiene and safety. Achieving an acceptable level of occupational risk in the formation of national policy in the field of occupational hygiene and safety can be considered as one of the main tasks.

Grid occupancy estimation for environment perception based on belief functions and PCR6

Moras, Julien; Dezert, Jean; Pannetier, Benjamin

2015-05-01

In this contribution, we propose to improve the grid map occupancy estimation method developed so far based on belief function modeling and the classical Dempster's rule of combination. Grid map offers a useful representation of the perceived world for mobile robotics navigation. It will play a major role for the security (obstacle avoidance) of next generations of terrestrial vehicles, as well as for future autonomous navigation systems. In a grid map, the occupancy of each cell representing a small piece of the surrounding area of the robot must be estimated at first from sensors measurements (typically LIDAR, or camera), and then it must also be classified into different classes in order to get a complete and precise perception of the dynamic environment where the robot moves. So far, the estimation and the grid map updating have been done using fusion techniques based on the probabilistic framework, or on the classical belief function framework thanks to an inverse model of the sensors. Mainly because the latter offers an interesting management of uncertainties when the quality of available information is low, and when the sources of information appear as conflicting. To improve the performances of the grid map estimation, we propose in this paper to replace Dempster's rule of combination by the PCR6 rule (Proportional Conflict Redistribution rule #6) proposed in DSmT (Dezert-Smarandache) Theory. As an illustrating scenario, we consider a platform moving in dynamic area and we compare our new realistic simulation results (based on a LIDAR sensor) with those obtained by the probabilistic and the classical belief-based approaches.

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

Eutrophication potential of lakes: an integrated analysis of trophic state, morphometry, land occupation, and land use

Directory of Open Access Journals (Sweden)

RF Silvino

Full Text Available AbstractDespite being inside a protected area, Lake Sumidouro has been impacted by the anthropogenic occupation of the surrounding area since the 1970’s, compromising the ecological integrity of the lake and the sustainable use of natural resources. This study examined the current trophic classification of the lake and developed methods for improving it through an integrated analysis of morphometric and limnological parameters, land use and land occupation in the watershed, and eutrophication potential. Data for the limnological parameters, land use and land occupation, and morphometric characteristics of Lake Sumidouro were collected in the rainy and dry seasons of 2009 and 2010. Depending on the trophic classification system used, Lake Sumidouro is classified as oligotrophic to hypereutrophic. In our study, the highest concentration of nutrients occurred in the rainy season, indicating that high nutrient inputs played an important role during this period. Areas of anthropogenic occupation comprised approximately 62.9% of the total area of the watershed, with pasture and urban settlement as the main types of land use. The influent total phosphorus load was estimated to be 15,824.3 kg/year. To maintain mesotrophic conditions, this load must be reduced by 29.4%. By comparing the isolated use of trophic state indices, this study demonstrated that comparing the trophic state classification with morphometric analyses, land use and land occupation types in the watershed, and potential phosphorus load provided better information to guide management actions for restoration and conservation. Furthermore, this approach also allowed for evaluating the vulnerability of the environment to the eutrophication process.

Occupancy estimation and the closure assumption

1. Recent advances in occupancy estimation that adjust for imperfect detection have provided substantial improvements over traditional approaches and are receiving considerable use in applied ecology. To estimate and adjust for detectability, occupancy modelling requires multiple surveys at a site and requires the assumption of 'closure' between surveys, i.e. no changes in occupancy between surveys. Violations of this assumption could bias parameter estimates; however, little work has assessed model sensitivity to violations of this assumption or how commonly such violations occur in nature. 2. We apply a modelling procedure that can test for closure to two avian point-count data sets in Montana and New Hampshire, USA, that exemplify time-scales at which closure is often assumed. These data sets illustrate different sampling designs that allow testing for closure but are currently rarely employed in field investigations. Using a simulation study, we then evaluate the sensitivity of parameter estimates to changes in site occupancy and evaluate a power analysis developed for sampling designs that is aimed at limiting the likelihood of closure. 3. Application of our approach to point-count data indicates that habitats may frequently be open to changes in site occupancy at time-scales typical of many occupancy investigations, with 71% and 100% of species investigated in Montana and New Hampshire respectively, showing violation of closure across time periods of 3 weeks and 8 days respectively. 4. Simulations suggest that models assuming closure are sensitive to changes in occupancy. Power analyses further suggest that the modelling procedure we apply can effectively test for closure. 5. Synthesis and applications. Our demonstration that sites may be open to changes in site occupancy over time-scales typical of many occupancy investigations, combined with the sensitivity of models to violations of the closure assumption, highlights the importance of properly addressing

Through this cross-sectional study the authors explore urinary incontinence in women in relation to occupational status and environment. Data from the fourth Korea National Health and Nutrition Examination Survey (2008-2009) were used (n = 5,928) excluding those aged under 19 or over 65 years, male, with renal disease, and with missing data. Urinary incontinence was prevalent in working women. Compared to unemployed women, the adjusted odds ratio (95% confidence intervals) for women working in services/sales was 1.62 (1.21-2.19); for paid workers was 1.81 (1.20-2.73); and for self-employed workers was 1.46 (1.05-2.03). Compared to unemployed women, the adjusted odds ratio for working women with a daytime work schedule was 2.14 (1.18-3.87), while for those with evening work schedules, it was 1.35 (1.05-1.74). Urinary incontinence was significantly associated with various occupational environments: an unclean and uncomfortable workplace, dangerous job and probability of accidents, feeling pressed for time, awkward position for long periods, and carrying heavy weights. These findings suggest that urinary incontinence was prevalent in working women and was associated with occupational status and working environment. Therefore, improving occupational status and environment for working women-such as modifying the working schedule, posture, and workplace atmosphere-are needed to prevent urinary incontinence.

Atomic energy, environment and energy conservation in Eastern Europe

International Nuclear Information System (INIS)

Kanno, Koko

1990-01-01

About 12 % of generated electric power is the nuclear power in Eastern European countries. Generally electric power is short in these countries, and as the countermeasures for environment, the promotion of nuclear power generation is considered. However, the public opinion opposing it is also strong. The situation in respective countries is briefly discussed. The prevention of warming of the earth and the reduction of carbon dioxide gas release are the largest environmental problems discussed in western countries, but in Eastern European countries, the far more primitive problem of the damage due to SO 2 is serious. Notwithstanding high sulfur brown coal is the main fuel, the installation of desulfurizing facilities has been neglected. The demand for the countermeasures to environmental pollution by people has become strong. The energy efficiency in Eastern European countries is poor, and it is one of the causes of environmental pollution. The industrial structure is centering around heavy industries which consume much energy, the energy loss arises due to the delay of equipment modernization, and the energy is cheap, so its saving is neglected. Energy conservation is important. (K.I.)

Letter to the Editor: License Portability for Occupational Audiologists is Essential

Directory of Open Access Journals (Sweden)

George R. Cook

2017-11-01

Full Text Available Occupational audiologists have a crisis in their profession and need advocates. These audiologists are primarily responsible for industrial hearing conservation programs and their compliance with multiple regulations, such as Occupational Safety and Health Administration (OSHA, Mine Safety and Health Administration (MSHA and the Federal Railroad Administration.  Occupational hearing programs, for the most part, are multi-state programs as companies and corporations are national organizations. Also, companies may contract services across state lines as local services may not be desired or available. Individual state telepractice regulations require audiologists who are professionally supervising these programs via the internet and phone, to secure licensure in each state. For this licensure redundancy, the cost in time and tracking are enormous.  It is imperative that the American Speech-Language-Hearing Association (ASHA, secure multistate licensure for speech-language pathologists and audiologists. For the profession of occupational audiology, it is essential. Keywords: Licensure, Occupational audiologists, Telehealth, Telepractice

Relaxed selection against accidental binding of transcription factors with conserved chromatin contexts.

Science.gov (United States)

Babbitt, G A

2010-10-15

The spurious (or nonfunctional) binding of transcription factors (TF) to the wrong locations on DNA presents a formidable challenge to genomes given the relatively low ceiling for sequence complexity within the short lengths of most binding motifs. The high potential for the occurrence of random motifs and subsequent nonfunctional binding of many transcription factors should theoretically lead to natural selection against the occurrence of spurious motif throughout the genome. However, because of the active role that chromatin can influence over eukaryotic gene regulation, it may also be expected that many supposed spurious binding sites could escape purifying selection if (A) they simply occur in regions of high nucleosome occupancy or (B) their surrounding chromatin was dynamically involved in their identity and function. We compared nucleosome occupancy and the presence/absence of functionally conserved chromatin context to the strength of selection against spurious binding of various TF binding motifs in Saccharomyces yeast. While we find no direct relationship with nucleosome occupancy, we find strong evidence that transcription factors spatially associated with evolutionarily conserved chromatin states are under relaxed selection against accidental binding. Transcription factors (with/without) a conserved chromatin context were found to occur on average, (87.7%/49.3%) of their expected frequencies. Functional binding motifs with conserved chromatin contexts were also significantly shorter in length and more often clustered. These results indicate a role of chromatin context dependency in relaxing selection against spurious binding in nearly half of all TF binding motifs throughout the yeast genome. 2010 Elsevier B.V.

2016-07-01

Life in isolated and confined environments (ICEs, e.g., polar stations, submarine or space missions), is subject to important constraints which can generate psychosociological impaired outcomes. This study investigated psychological, social, occupational and cultural variables which are among the most important determinants in adaptation to a one-year wintering in Antarctica with 13 international participants. Our findings confirm and give further insight into the role of social (Cohesiveness, Social Support) and occupational (Implementation / Preparedness, Counterproductive Activity, Decision Latitude and Psychological Job Demands) dimensions of adaptation to ICE environments. Relationships between various social and occupational dimensions studies reflected detrimental effects ranging from decrements in cohesiveness, social support and work performance which differed across professional status and multicultural factors. These psychosocial issues have important implications for pre-mission selection and training, monitoring and support of crews during the mission and post-mission readaptation. Operational recommendations are suggested to improve adaptation, success and well-being for long-term ICE missions, e.g., to Mars and beyond.

A collaborative approach with teachers is required when providing community-based occupational therapy to educationally at risk children. Collaborators share common goals and interact and support each other but challenges arise in providing collaborative occupational therapy in settings outside the school environment. The aim of this study was to capture experiences of teachers and occupational therapists working within a school-based occupational therapy program to determine if their experiences could inform collaborative practice. In this pilot study, participant responses to questionnaires (n = 32) about their experiences formed the basis for focus groups and individual interviews. Two focus group were conducted, one with teachers (n = 11) and one with occupational therapy participants (n = 6). Individual interviews were conducted with the supervising occupational therapist, school principal and two leading teachers. Descriptive statistics were used to analyse the data from closed questions, and thematic analysis using a constant comparison approach was used to analyse open ended questions, focus groups and interviews. Three main themes emerged: (i) the need for occupational therapists to spend time in the school, to explain their role, build relationships, understand classroom routines and the teacher role; (ii) occupational therapists need to not see themselves as the expert but develop equal partnerships to set collaborative goals and (iii) occupational therapists advocating for all parties to be informed throughout the occupational therapy process. The pilot study findings identified teacher and therapist experiences within the school setting that could inform improved collaborative practice with teachers and community-based occupational therapists and these findings warrant further investigation. © 2013 Occupational Therapy Australia.

The article aims to provide an occupational perspective on the lives of people with a serious mental illness who have committed a criminal offense and are incarcerated in a secure environment. The article focuses on ways that institutions fail to meet occupational needs of such persons and the challenges for mental health and psychiatric rehabilitation professionals, including occupational therapists, in providing psychiatric rehabilitation to facilitate community integration and participation. The concepts of occupational deprivation, occupational imbalance, habits and occupational enrichment provide useful theoretical constructs underpinning practice endeavors. Ovid using Medline, PsychINFO, CINAHL, OTDBase, and ProQuest. There is a priority for research to validate tools to assess outcomes of occupations in secure settings, and the use of these tools to focus on which rehabilitation practices are correlated with establishing positive outcomes after release. Research evidence is also needed that demonstrates that occupational enrichment can result in observable and measurable outcomes that mitigate the negative effects of incarceration and support successful community re-entry of persons with mental illnesses who are offenders.

The aim of this study was to investigate whether a four-month occupational based health-promoting programme for older persons living in community dwellings could maintain/improve their general health and well-being. Further, the aim was to explore whether the programme facilitated the older persons' occupational adaptation. The study had a quasi-experimental design, with a non-equivalent control group combined with semi-structured interviews. The intervention group comprised 22 participants, and the control group 18. Outcomes were measured using the Short Form 36, Life Satisfaction Index-Z and Meaningful Activity Participation Assessment. Content analysis, based on concepts from the Model of Occupational Adaptation, was used to analyse the interviews. The intervention group showed statistically significant improvements in general health variables such as vitality and mental health, and positive trends for psychological well-being. There were no statistically significant differences between the intervention group and the control group, but the groups were not fully matched. The qualitative analysis based on Occupational Adaptation pointed out social aspects as a compliment to the overall results. Participating in meaningful, challenging activities in different environments stimulates the occupational adaptation process; this is something occupational therapists could use to empower older persons to find their optimal occupational lives.

Improvisation as an adaptive strategy for occupational therapy practice.

Science.gov (United States)

Krusen, Nancy E

2012-01-01

ABSTRACT As health care environments become increasingly complex, practitioners must develop new adaptive skills to master practice. The idea of using theatrical improvisation (improv) in health care is relatively new. Occupational therapy students were taught a module of improvisational techniques as part of an academic seminar, learning improvisation rules, and enacting solutions to typical daily professional challenges. The purpose of this article is to recommend improvisational techniques as an adaptive skill to effectively blend art and science for occupational therapy practice in fast-paced and unpredictable health care environments.

Environment conservation by way of official notice or recommendations

International Nuclear Information System (INIS)

Ossenbuehl, F.

1986-01-01

Official notice or recommendations belong to the self-evident instruments of government authorities to fulfill their functions. According to their typical type of effect, in the system of powers to act, these instruments belong to the group of the simple administrative acts of state. They are thus not of direct legal interest, at first sight. However, the Chernobyl accident and its consequences have just been the latest opportunity to realise that official notice or recommendations issued by state authorities may have a far-reaching impact on the consumers' behaviour, and hence on the market situation. The book in hand discusses legal problems in connection with such impact, taking as an example the field of environment conservation and related precautionary activities. The main issues dealt with refer to the permissibility by law and the formal status of official notice warning of the use of environmentally harmful products, to legal protection in case of unlawful warnings or recommendations, and to possible liabilities. The book in hand developed from a legal expertise made on behalf of the German Federation of Toilet Articles and Detergents Producers is intended to show that the increasingly used informal administrative instruments of official notice or recommendations ought to be integrated into the system of administrative law.

The physical environment and occupant thermal perceptions in office buildings. An evaluation of sampled data from five European countries

Energy Technology Data Exchange (ETDEWEB)

Stoops, J L [Chalmers Univ. of Tech., Goeteborg (Sweden). Dept. of Building Services Engineering

2002-02-01

The results from a large field study of thermal comfort in European office buildings are reported. Measurements of physical environmental conditions and occupant perceptions were collected over sixteen months from twenty-six different office buildings located in France, Greece, Portugal, Sweden and the UK. This thesis focuses on the physical environmental measurements and occupant thermal perceptions; however, additional variables with connections to environmental satisfaction are also examined. An overview of human comfort theory is presented to help place this thesis in appropriate context. The overview presents thermal comfort issues within a broad framework of human response to the environment including physical, physiological. behavioural, psychological and other variables. A more narrowly focused overview of current thermal comfort research is also included. The work attempts to show relationships and produce useful information from the data set using graphical methods, especially lowess, a locally weighted regression based scatter plot smoothing technique. The objective of using this approach is to literally show the relationships visually. This approach allows the data set itself to illustrate the actual thermal conditions in European office buildings and the occupant perceptions of those conditions along with illustrating relationships. The data is examined in some detail with key relationships identified and explored. Significant differences between countries, both for the physical conditions and the perceptions of those conditions are identified. In addition, the variation over the course of the year for each country is explored. The relationship of daily average outdoor temperatures to indoor temperatures and indoor temperature perceptions is found to be critically important. The relationships, which appear to drive perceptions of thermal comfort, occur in complex ways, making simple, all encompassing explanations impossible. The nature and size of the

Terrestrial carnivores typically have large home ranges and exist at low population densities, thus presenting challenges to wildlife researchers. We employed multiple, noninvasive survey methods—scat detection dogs, remote cameras, and hair snares—to collect detection–nondetection data for elusive American black bears (Ursus americanus), fishers (Martes pennanti), and bobcats (Lynx rufus) throughout the rugged Vermont landscape. We analyzed these data using occupancy modeling that explicitly incorporated detectability as well as habitat and landscape variables. For black bears, percentage of forested land within 5 km of survey sites was an important positive predictor of occupancy, and percentage of human developed land within 5 km was a negative predictor. Although the relationship was less clear for bobcats, occupancy appeared positively related to the percentage of both mixed forest and forested wetland habitat within 1 km of survey sites. The relationship between specific covariates and fisher occupancy was unclear, with no specific habitat or landscape variables directly related to occupancy. For all species, we used model averaging to predict occurrence across the study area. Receiver operating characteristic (ROC) analyses of our black bear and fisher models suggested that occupancy modeling efforts with data from noninvasive surveys could be useful for carnivore conservation and management, as they provide insights into habitat use at the regional and landscape scale without requiring capture or direct observation of study species.

To explore the nature and severity of occupational injuries among construction workers and its risk factors in Hong Kong. One hundred and twenty-two injured construction workers in a public hospital and an equal number of workmate controls were studied. Contents included socio -demographic characteristics, the availability and use of safety equipment, smoking and alcohol consumption, etc. Abbreviated injury scale (AIS) and injury severity score (ISS) were employed for describing the nature, pattern and severity of injuries. Single injuries were seen in 80% of cases. Of 149 injuries classified by body region, 49% were external, 26% involved either the upper or lower extremities, and 11% were spinal injuries. Working at height was associated with the injury severity score. Safety hazards were identified in the work environment in 68% of the cases. Significant odds ratios for accidents were obtained for 'no formal education', 'non safety training' and 'current smokers'. The results implicated that construction was a hazardous occupation in Hong Kong. Improving the work environment and promoting safety education among construction workers would be helpful for minimizing or eliminating occupational injuries in construction occupation in Hong Kong.

Since the working medical personnel including dentists and dental technicians mainly use their hands, it is understandable that the most common occupational disease amongst medical personnel is contact dermatitis (CD) (80%-90% of cases). Development of occupational CD is caused by contact of the skin with various substances in occupational environment. Occupational etiologic factors for dental personnel are foremost reactions to gloves containing latex, followed by various dental materials (e.g., metals, acrylates), detergents, lubricants, solvents, chemicals, etc. Since occupational CD is relatively common in dental personnel, its timely recognition, treatment and taking preventive measures is needed. Achieving skin protection at exposed workplaces is of special importance, as well as implementing necessary measures consequently and sufficiently, which is sometimes difficult to achieve. Various studies have shown the benefit of applying preventive measures, such as numerous protocols for reducing and managing latex sensitivity and other forms of CD in dentistry. Active involvement of physicians within the health care system, primarily dermatologists, occupational medicine specialists and general medicine doctors is needed for establishing an accurate medical diagnosis and confirmation of occupational skin disease.

Trees in Urban and City Environments: a review of the selection criteria with particular reference to nature conservation in New Zealand Cities

2008-07-01

Full Text Available The overall aim of this research was to review the general criteria for selection of trees for urban environments and city environments. The reason for this research was to assess the extent to which criteria for tree selection can contribute to nature conservation in cities. We conducted an extensive review of the literature, looking for publications about the selection criteria. In particular, we looked for any previous published reviews of the criteria. With reference to the criteria used in New Zealand, we undertook an unstructured review of the practices adopted in most cities. A review of the literature revealed many publications about different criteria but only one publication in which there was a general review of the criteria used for selecting trees for urban environments. By way of contrast, lists of tree species deemed to be suitable (or unsuitable for urban planting are widely available, and some include information about selection criteria, but often with little background explanation. Worldwide, commonly used criteria included commercial availability of species, compatibility with urban environments, landscape design, low maintenance, avoidance of nuisance factors and historical practice. The most common criteria are concerned with the concept of choosing species compatible with local climate and soils. Anecdotal evidence suggests that more and more cities are using a mix of criteria including those that may contribute to conservation and restoration of native biota. We suggest that there should be greater use of ecological, genetic and biogeographical criteria to meet the needs of nature conservation in New Zealand cities.

Full Text Available Background: This study integrates research on practice applications of the construct of occupational adaptation with occupational therapy and occupational science literature. Method: Using Arksey and O’Malley’s 5-step Scoping Study Framework (2005, we conducted a scoping review of 74 articles from five online databases and literature hand-searching and performed quantitative and thematic analyses. Results: The Occupational Adaptation model (Schkade & Schultz, 1992; n = 74 and the Model of Human Occupation (Kielhofner, 2008; n = 37 were the most frequently cited literature influences. Occupational adaptation has been defined as a process (n = 49, an outcome (n = 37 and both a process and outcome (n = 12 of occupational participation. Four qualitative themes emerged to support the definitions of occupational adaptation from the literature. Occupational adaptation was defined as (a a product of engagement in occupation, (b a transaction in the environment, (c a response to change and life transitions; and (d a formation of a desired sense of self. Discussion: Evidence of occupational adaptation as a viable construct warrants further research to operationalize practice and outcomes.

Position of the American Dietetic Association: dietetics professionals can implement practices to conserve natural resources and protect the environment. (Previously titled "natural resource conservation and waste management").

Science.gov (United States)

2001-10-01

It is the position of the American Dietetic Association to encourage environmentally responsible practices that conserve natural resources, minimize the quantity of waste that is generated, and have the least adverse affect on the health of all living organisms and the environment. All components of the food system, from farmer to consumer, are affected by the availability and cost of energy and the availability and quality of water. Outdoor and indoor air quality significantly impacts the health of all living organisms. Decisions that dietetics professionals make as practitioners and consumers can affect the quantity and type of solid waste generated. The demand for natural resources should be evaluated when selecting the most cost-effective, environmentally sensitive approach to the management of solid waste. Special precautions are needed when using and disposing of hazardous and medical waste to protect the safety of our clients and employees. This position paper provides information and resources for dietetics professionals for addressing the complexity of the environmental issue presented. Conservation strategies are identified that dietetics professionals can use in their worksites and at home. These conservation practices may reduce cost and decrease the environmental impact we have on our communities and the world.

Monitoring Least Bitterns (Ixobrychis exilis) in Vermont: Detection probability and occupancy modeling

Science.gov (United States)

Cherukuri, Aswini; Strong, Allan; Donovan, Therese M.

2018-01-01

Ixobrychus exillis (Least Bittern) is listed as a species of high concern in the North American Waterbird Conservation Plan and is a US Fish and Wildlife Service migratory bird species of conservation concern in the Northeast. Little is known about the population of Least Bitterns in the Northeast because of their low population density, tendency to nest in dense wetland vegetation, and secretive behavior. Urban and agricultural development is expected to encroach on and degrade suitable wetland habitat; however, we cannot predict the effects on Least Bittern populations without more accurate information on their abundance and distribution. We conducted surveys of wetlands in Vermont to assess the efficacy of a monitoring protocol and to establish baseline Least Bittern abundance and distribution data at a sample of 29 wetland sites. Surveys yielded detections of 31 individuals at 15 of 29 sites across 3 biophysical regions and at 5 sites where occupancy had not been previously reported. Probability of occupancy was positively related to wetland size and number of patches, though the relationships were not strong enough to conclude if these were true determinants of occupancy. Call—response broadcast surveys yielded 30 detections, while passive surveys yielded 13. Call—response broadcasts (P = 0.897) increased the rate of detection by 55% compared to passive surveys (P = 0.577). Our results suggest that call—response broadcast surveys are an effective means of assessing Least Bittern occupancy and may reduce bias in long-term monitoring programs.

Use of Occupancy Models to Evaluate Expert Knowledge-based Species-Habitat Relationships

Directory of Open Access Journals (Sweden)

Monica N. Iglecia

2012-12-01

Full Text Available Expert knowledge-based species-habitat relationships are used extensively to guide conservation planning, particularly when data are scarce. Purported relationships describe the initial state of knowledge, but are rarely tested. We assessed support in the data for suitability rankings of vegetation types based on expert knowledge for three terrestrial avian species in the South Atlantic Coastal Plain of the United States. Experts used published studies, natural history, survey data, and field experience to rank vegetation types as optimal, suitable, and marginal. We used single-season occupancy models, coupled with land cover and Breeding Bird Survey data, to examine the hypothesis that patterns of occupancy conformed to species-habitat suitability rankings purported by experts. Purported habitat suitability was validated for two of three species. As predicted for the Eastern Wood-Pewee (Contopus virens and Brown-headed Nuthatch (Sitta pusilla, occupancy was strongly influenced by vegetation types classified as "optimal habitat" by the species suitability rankings for nuthatches and wood-pewees. Contrary to predictions, Red-headed Woodpecker (Melanerpes erythrocephalus models that included vegetation types as covariates received similar support by the data as models without vegetation types. For all three species, occupancy was also related to sampling latitude. Our results suggest that covariates representing other habitat requirements might be necessary to model occurrence of generalist species like the woodpecker. The modeling approach described herein provides a means to test expert knowledge-based species-habitat relationships, and hence, help guide conservation planning.

Even with global support for tiger (Panthera tigris) conservation their survival is threatened by poaching, habitat loss and isolation. Currently about 3,000 wild tigers persist in small fragmented populations within seven percent of their historic range. Identifying and securing habitat linkages that connect source populations for maintaining landscape-level gene flow is an important long-term conservation strategy for endangered carnivores. However, habitat corridors that link regional tiger populations are often lost to development projects due to lack of objective evidence on their importance. Here, we use individual based genetic analysis in combination with landscape permeability models to identify and prioritize movement corridors across seven tiger populations within the Central Indian Landscape. By using a panel of 11 microsatellites we identified 169 individual tigers from 587 scat and 17 tissue samples. We detected four genetic clusters within Central India with limited gene flow among three of them. Bayesian and likelihood analyses identified 17 tigers as having recent immigrant ancestry. Spatially explicit tiger occupancy obtained from extensive landscape-scale surveys across 76,913 km(2) of forest habitat was found to be only 21,290 km(2). After accounting for detection bias, the covariates that best explained tiger occupancy were large, remote, dense forest patches; large ungulate abundance, and low human footprint. We used tiger occupancy probability to parameterize habitat permeability for modeling habitat linkages using least-cost and circuit theory pathway analyses. Pairwise genetic differences (FST) between populations were better explained by modeled linkage costs (r>0.5, p<0.05) compared to Euclidean distances, which was in consonance with observed habitat fragmentation. The results of our study highlight that many corridors may still be functional as there is evidence of contemporary migration. Conservation efforts should provide legal status

The professional work of small animal veterinary staff encompasses a wide diversity of demanding tasks. This has prompted a number of studies covering physical, chemical, biological, ergonomic, or psychological hazards, as well as their health effects upon veterinary workers. However, such results were obtained from self-reported surveys (via paper or online). This study reports the identification of potential hazards and provides a risk assessment of 15 veterinary clinics based on data from walk-through surveys, interviews with workers, and quantification of indoor air quality parameters including concentration of volatile organic compounds (total, isoflurane, and glutaraldehyde). The risk arising from X-ray exposure was unacceptable in seven clinics; X-ray examination should be discontinued in the absence of isolated radiation rooms, poor safety practices, and lack of personal protective equipment. Ergonomic-related hazards and work practices should be revised as soon as possible, considering that improper postures, as well as moving and lifting heavy animals are major causes of musculoskeletal disorders. The risk levels were, in general, small or medium (acceptable) with regard to exposure to physical hazards (such as bites, scratches, cuts, and burns) and biological hazards. It was observed that the indoor air quality parameters including temperature, respirable particulate matter and total volatile organic compounds do not indicate a comfortable workplace environment, requiring clinics' attention to keep the safe environment. The veterinarians and nurses were exposed to isoflurane (above 2 ppm) during surgery if an extractor system for waste gas was used instead of a scavenging system. Finally, veterinary workers did not possess any type of training on occupational safety and health issues, even though they recognized its importance.

We collected information necessary for conducting occupational health activities in Thailand with regard to occupational safety and health management systems (OSHMS). Based on an information collection check sheet developed in our previous research, we conducted a literature research and visited four local business bases, one ISO certification body and two higher educational institutions. The legal framework concerning occupational health in Thailand consists of the Occupational Safety, Health and Environment Act of 2011 and 13 ordinances from the Ministry of Labor under that act. The original OSHMS standards for Thailand have been published, and the number of companies, especially large ones, introducing systems conforming to these standards has increased in recent years. For occupational health specialists, there are training programs for specialized occupational health physicians, professional safety officers and occupational nurses. Professional safety officers also play a central role in occupational health in the workplace. In Thailand, it is necessary to ensure compliance with related acts and regulations, and to conduct voluntary activities that satisfy workplace conditions as based on the OSHMS standards. Additionally, to improve occupational health performance, it is essential to use high-quality external services and/or occupational health professionals. Headquarters of Japanese companies have considered taking countermeasures such as recommending active use of professional safety officers, as well as issuing global standards.

Sustainable school buildings hold much promise to reducing operating costs, improve occupant well-being and, ultimately, teacher and student performance. However, there is a scarcity of evidence on the effects of sustainable school buildings on health and performance indicators. We sought to create a framework for a multidisciplinary research agenda that links school facilities, health, and educational outcomes. We conducted a nonsystematic review of peer review publications, government documents, organizational documents, and school climate measurement instruments. We found that studies on the impact of physical environmental factors (air, lighting, and thermal comfort) on health and occupant performance are largely independent of research on the social climate. The current literature precludes the formation of understanding the causal relation among school facilities, social climate, occupant health, and occupant performance. Given the average age of current school facilities in the United States, construction of new school facilities or retrofits of older facilities will be a major infrastructure investment for many municipalities over the next several decades. Multidisciplinary research that seeks to understand the impact of sustainable design on the health and performance of occupants will need to include both an environmental science and social science perspective to inform best practices and quantification of benefits that go beyond general measures of costs savings from energy efficiencies. © 2017, American School Health Association.

The ability of the earth to sustain health among humans and in the natural world is under threat from overpopulation, environmental degradation, and climate change. These global threats are anticipated to harm health and human occupation in many direct and indirect ways. Strategies are needed to mitigate the effects of these threats and to build individual and community capacities to foster resilience. This paper links issues of sustainability with occupational therapy philosophy and discusses how employing a sustainability lens with professional reasoning can help practitioners integrate sustainability into their practice. Human occupation is inseparable from the environments in which people live. Human occupation has caused the current environmental crisis, and targeted human action is required to safeguard future health and well-being. Occupational therapists have an ethical obligation to use professional reasoning strategies that, taken collectively, can help to build a sustainable and resilient future.

The ICRP Committee stated in their publications that it is important to compare the total harm that may be caused by the radiation with the total harm involved in other occupations, with respect to fatal or minor injury, occupational disease, or the effects of mutagenesis in the working environment. Death has commonly been used as an index of the comparative safety or harm of different industries, and the frequency of death attributable to occupational causes already has a certain validity. In this way, assessment was made on the yearly trend of change in the fatality rates due to occupational work in seven categories of industry in Japan during the period from 1975 to 1984. furthermore, the frequency of injuries of defined severity in occupational hazards, fatality rates of accidents and diseases due to occupational work, and also commuting accidents to and from work were examined

Given the increased prevalence of cancer, respiratory diseases, and reproductive disorders, for which multifactorial origins are strongly suspected, the impact of the environment on the population represents a substantial public health challenge. Surveillance systems have become an essential public health decision-making tool. Networks have been constructed to facilitate the development of analyses of the multifactorial aspects of the relationships between occupational contexts and health. The aim of this study is to develop and present an approach for the optimal exploitation of observational databases to describe and improve the understanding of the (occupational) environment–health relationships, taking into account key multifactorial aspects. We have developed a spectral analysis (SA) approach that takes into account both the multi-exposure and dynamic natures of occupational health problems (OHPs) and related associations. The main results of this paper are to present the construction method of the “spectrum” and “spectrosome” of OHPs (range and structured list of occupational exposures) and describe the information contained therein with an illustrative example. The approach is illustrated using the case of non-Hodgkin lymphoma (NHL) from the French National Occupational Diseases Surveillance and Prevention Network database as a working example of an occupational disease. We found that the NHL spectrum includes 40 sets of occupational exposures characterized by important multi-exposures, especially solvent combinations or pesticide combinations, but also specific exposures such as polycyclic aromatic hydrocarbons, formaldehyde and ionizing radiation. These findings may be useful for surveillance and the assessment of occupational exposure related to health risks. PMID:29304043

The Study Model for Future Occupational Health (funded by a research grant from the Ministry of Health, Welfare and Labor) is a joint research project involving various organizations and agencies undertaken from 2002 to 2004. Society has undergone a dramatic transformation due to technological developments and internationalization. At the same time a low birth rate and an aging population have resulted in an increase in both the percentage of workers experiencing strong anxiety and stress in relation to their jobs and the working environment and the number of suicides. As a natural consequence, occupational health services are now expected to provide EAP, consulting and other functions that were formerly considered outside the realm of occupational health. In consideration of this background, the present study propose the following issues to provide a model for future occupational health services that meet the conditions presently confronted by each worker. 1. How to provide occupational health services and occupational physicians' services: 1) a basic time of 20 minutes of occupational health services per year should be allotted to each worker and to all workers; 2) the obligatory regulations should be revised to expand the obligation from businesses each with 50 or more employees under the present laws to businesses each with 30 or more employees. 2. Providers of occupational health services and occupational physicians' services: (1) reinforcement of outside occupational health agencies; (2) fostering occupational health consultant firms; (3) development of an institute of occupational safety and health; (4) support of activities by authorized occupational physicians in the field; (5) expanding of joint selection of occupational physicians including subsidy increase and the extension of a period of subsidy to five hears; (6) licensing of new entry into occupational health undertaking. 3.

Occupational hearing loss is one of the most common work-related illnesses in the United States (US). From 22 to 30 million US workers are exposed to hazardous noise levels at work, and 25% of these workers will develop permanent hearing loss. Hearing loss from noise is slow and painless, and you can have a disability before you notice it. This course presents the hazards associated with workplace noise, the purpose and elements of the Los Alamos National Laboratory (LANL) Hearing Conservation Program (HCP), and controls that are available to reduce your exposure to hazardous levels of noise.

The aim of this article is to reduce the risk of occupational hazards and improve safety conditions by enhancing hazard knowledge and identification as well as improving safety behavior for freight port enterprises. In the article, occupational hazards to health and their prevention measures of freight port enterprises have been summarized through a lot of occupational health evaluation work, experience and understanding. Workers of freight port enterprises confront an equally wide variety of chemical, physical and psychological hazards in production technology, production environment and the course of labor. Such health hazards have been identified, the risks evaluated, the dangers to health notified and effective prevention measures which should be put in place to ensure the health of the port workers summarized. There is still a long way to go for the freight port enterprises to prevent and control the occupational hazards. Except for occupational hazards and their prevention measures, other factors that influence the health of port workers should also be paid attention to, such as age, work history, gender, contraindication and even the occurrence and development rules of occupational hazards in current production conditions.

Chemical processes taking place in indoor environments can significantly alter the nature and concentrations of pollutants. Exposure to secondary contaminants generated in these reactions needs to be evaluated in association with many aspects of buildings to minimize their impact on occupant health and well-being. Focusing on indoor ozone chemistry, we describe alternatives for improving indoor air quality by controlling chemical changes related to building materials, ventilation systems, and occupant activities.

2004 was another good year for publications on environmental and occupational disorders in our journal. The major focus is clearly on the environment and particularly on environmental risk factors for sensitization and asthma. There is a growing consensus that exposure to pets is good, provided there is enough of it. Low levels enhance sensitization, and higher levels protect against the consequences of that sensitization. Following on from previous work on cockroaches, we now see allergy to feral mice as an emergent problem--at least we now have the tools to study this properly. Emphasis seems to be swinging away from the outdoor environment as a cause of allergic disease and toward the indoor environment, which is, after all, where most of us spend most of our lives. New techniques for studying isocyanate allergy might kindle a revival of interest in the mechanisms of occupational asthma caused by low-molecular-weight compounds. But for all types of occupational allergy, prevention remains key, and it is good to see that comprehensive programs of allergen reduction can pay off in reduced rates of latex allergy in health care workers. Further work in the area of recombinant allergens is welcome but needs soon to be translated into new diagnostic and therapeutic strategies. This sector of allergy research remains vibrant, and the editors will continue to welcome outstanding contributions in this area.

The Effect of Personality on Occupational Stress in Veterinary Surgeons.

Statistics show that veterinary surgeons are in one of the professions with the highest suicide rates. This indicates the sector has significant well-being issues, with high levels of occupational stress and burnout. Previous research has focused on environmental factors in isolation, overlooking the influence of personality. This study aimed to establish that personality is a better predictor of occupational stress than environment. UK veterinary surgeons (n=311) completed an online survey composed of three questionnaires; the NEO Five-Factor Inventory, the Maslach Burnout Inventory, and the Job Stress Survey. Multiple regression analysis revealed that personality is a better predictor of occupational stress than environment (poccupational stress (pstress are depression (p=.002) and anger hostility (p=.005). Demographic factors such as the number of years the veterinarian has been qualified acted as a mediator between depression and occupational stress (poccupational stress (p=.028). Overall findings suggest that newly qualified veterinarians are at greater risk of suffering from high levels of occupational stress than those well established in the profession, and that veterinarians with higher levels of depression and anger hostility are likely to experience greater levels of occupational stress. Implications highlight the need for greater awareness of potentially susceptible personality traits in the veterinary admissions process. This would allow for the identification of those at risk and the implementation of interventions.

How conserved are the conserved 16S-rRNA regions?

Full Text Available The 16S rRNA gene has been used as master key for studying prokaryotic diversity in almost every environment. Despite the claim of several researchers to have the best universal primers, the reality is that no primer has been demonstrated to be truly universal. This suggests that conserved regions of the gene may not be as conserved as expected. The aim of this study was to evaluate the conservation degree of the so-called conserved regions flanking the hypervariable regions of the 16S rRNA gene. Data contained in SILVA database (release 123 were used for the study. Primers reported as matches of each conserved region were assembled to form contigs; sequences sizing 12 nucleotides (12-mers were extracted from these contigs and searched into the entire set of SILVA sequences. Frequency analysis shown that extreme regions, 1 and 10, registered the lowest frequencies. 12-mer frequencies revealed segments of contigs that were not as conserved as expected (≤90%. Fragments corresponding to the primer contigs 3, 4, 5b and 6a were recovered from all sequences in SILVA database. Nucleotide frequency analysis in each consensus demonstrated that only a small fraction of these so-called conserved regions is truly conserved in non-redundant sequences. It could be concluded that conserved regions of the 16S rRNA gene exhibit considerable variation that has to be considered when using this gene as biomarker.

Occupational hearing loss in Korea.

Kim, Kyoo Sang

2010-12-01

In this article, current status of noise exposure in workplaces, trend of workers with noise-induced hearing loss (NIHL), and prevalence of NIHL in workers by industry and job category in Korea were reviewed. In addition, trends of research on the audiological effects such as hearing loss from noise and occupational hearing loss from non-noise in Korea were addressed through reports in industrial audiology. Though noise exposure level has improved, noise still shows the highest rate of cases exceeding exposure limit among workplace hazards. NIHL is the most common occupational disease except work-related disease such as musculoskeletal disorders and cerebrovascular diseases, and NIHL prevalence is thought to be much higher than reported in official publications. Noise affecting hearing comes from various sources such as workplaces, military settings, areas with exposure to high noise, and specific noise sources. There is also occupational hearing loss by non-noise including chemicals such as organic solvents and heavy metals, barotrauma, and trauma due to welding spark. Noise affects daily life through audiological effects such as hearing loss and tinnitus, non-audiological physical effects (e.g., cardiovascular), and psychosocial and behavioral effects. Development of systematic and comprehensive hearing conservation programs for lowering the noise level in workplaces and preventing the NIHL, and preparation of technological, administrative system for its settlement at workplace are urgently needed.

Does changing context play a role in the decline in ADHD symptoms in adulthood? Insufficient research has explored the functioning of adults with ADHD. As adults, individuals with ADHD have significantly more latitude to control aspects of their day-to-day environments. Do the new contexts young adults find themselves in alter their experience of ADHD? Are there particular occupational or educational contexts in which young adults report functioning better than others? To examine this issue, we conducted semi-structured interviews at four North American sites in 2010-11 with 125 young adults, originally diagnosed with ADHD as children, regarding their work and post-secondary educational environments. Many subjects describe their symptoms as context-dependent. In some contexts, participants report feeling better able to focus; in others, their symptoms—such as high energy levels—become strengths rather than liabilities. Modal descriptions included tasks that were stressful and challenging, novel and required multitasking, busy and fast-paced, physically demanding or hands-on, and/or intrinsically interesting. Consistent with a developmental psychopathology framework, ADHD is experienced as arising from an interaction between our subjects and their environments. These findings demonstrate the need to account for the role of context in our understanding of ADHD as a psychiatric disorder, especially as it manifests in young adulthood. PMID:27299978

Occupational Safety and Related Impacts on Health  and the Environment.

Watterson, Andrew

2016-10-05

The inter-relationship between safety, health and the 'environment' is a complex and at times a relatively neglected topic. In this issue, 'safety' is often viewed by contributors as 'health and safety' and includes occupationally-related ill health as well as injury or harm to employees and the wider public. 'Environment' is also interpreted in the widest sense covering both physical and work environments with upstream work hazards presenting risks to downstream communities. The focus is very much on exploring and where possible addressing the challenges, some old and some facing workers in a range of public and private settings and also at times their nearby communities. The 19 papers in the issue cover public and private sectors, global and very local populations, macro-theoretical perspectives, large epidemiological and some single factory or hospital site small case studies. A number of the papers are just beginning to explore and draw out for the first time the risks from hazards in their part of the world. The methodologies adopted also range from lab-based studies through ergonomic assessments and interventions to therapeutic approaches.

Ganesh, C S; Krishnan, R

2016-06-01

A literature review of 16 papers on occupational injury research in Malaysia published during a 13-year period from 2000-2013 was carried out. The objective of this review and article selection was based on relevance to the research theme and mention of areas for future research. Most of the publications have focused on descriptive epidemiology, management practices, worker's knowledge, attitude, training, and rehabilitation services. The transportation, agriculture and construction sectors were found to be the most hazardous sectors and would benefit the most from Occupational Safety & Health (OSH) research and interventions. There is a strong need to develop a national injury surveillance system and also a mechanism to ensure adherence to the Occupational Safety & Health Act(OSHA) 1994. Detailed description and identification of risk factors for occupational injury in the environment, including machinery and equipment used was generally lacking. Future research on occupational injury should focus on surveillance to determine the magnitude of occupational injuries, determination of risk factors, identifying costeffective interventions (such as enforcement of OSHA regulations), and assessment of rehabilitation services. Relevant government agencies, universities, corporate sector and occupational safety organizations need to play a proactive role in identifying priority areas and research capacity building. Funding for occupational injury should be commensurate with the magnitude of the problem.

Full Text Available SUMMARY Objective: To analyze the epidemiological profile, risk factors in the workplace environment and prevention methods for professionals at risk of skin cancer. Method: A systematic review of articles on occupational skin cancer, published in the Lilacs, Scielo, Medline and Cochrane Library from January 1st, 2008, to December 31st, 2013, was performed. The search included the following terms: “neoplasias cutâneas” (DeCS, “exposição ocupacional” (DeCS, “epidemiologia” (DeCS as well as the keyword “prevenção”, and their equivalents in English. Results: After analyzing the titles and summaries of articles, the search strategy resulted in 83 references, of which 22 articles met the eligibility criteria. Discussion: We found that sun exposure is the main occupational risk factor for skin cancer, causing outdoor workers to be the most vulnerable to developing occupational skin cancer. Professionals with low levels of education and European descent are at increased risk of developing this cancer. Conclusion: Outdoor workers are more vulnerable to developing occupational skin cancer, estimating that professionals with low level of education and European descent are at increased risk of developing this cancer. Therefore, companies need to invest more in the health of workers by providing protective equipment and thus preventing occupational skin cancer.

With the reform of the education system in China, teachers are suffering from more occupational strain, which is believed to impair their working state indirectly and affect their health. This study assessed occupational strain and explored the related factors among Chinese teachers. Cross-sectional with cluster sampling. The study population was composed of 3570 school teachers working in 64 primary and middle schools in Heping District in Shenyang, China. Data were collected using a self-administered questionnaire (the Chinese version of the Occupational Stress Inventory scale). Multivariate linear regression analyses were performed to study the factors related to occupational strain. The average score on the Personal Strain Questionnaire (PSQ) for the whole study population was 106.5 (107.5 in men and 106.3 in women). Teachers with chronic disease, a greater number of days of sick leave, recent experience of a stressful life event and divorced/separated/widowed status tended to suffer greater strain than their peers. Regression analyses showed that the PSQ score was significantly associated with role overload, role boundary, responsibility and physical environment, and inversely associated with recreation and rational coping. The most crucial predictors of occupational strain were chronic disease, days of sick leave, recent experience of a stressful life event and marital status. Being a class teacher was the strongest indicator of interpersonal strain. Self-care was associated with vocational strain and psychological strain, and inversely associated with physical strain. Most teachers in this study experienced a high degree of occupational strain. Chronic disease, days of sick leave, recent experience of a stressful life event and divorced/separated/widowed status played prominent roles in occupational strain. In addition, role overload, role boundary, responsibility and physical environment induce occupational strain, while recreation and rational coping have

Integration of radiation protection in occupational health and safety managementsystems - legal requirements and practical realization at the example of the Fraunhofer occupational health and safety management system FRAM

Lambotte, S.; Severitt, S.; Weber, U.

2002-01-01

The protection of the employees, the people and the environment for the effects of radiation is regulated by numerous laws and rules set by the government and the occupational accident insurances. Primarily these rules apply for the responsibles, normally the employer, as well as for the safety officers. Occupational safety management systems can support these people to carry out their tasks and responsibilities effectively. Also, a systematic handling of the organisation secures that the numerous duties of documentation, time-checking of the proof-lists and dates are respected. Further more, the legal certainty for the responsibles and safety officers will be raised and the occupational, environment, radiation and health protection will be promoted. At the example of the Fraunhofer occupational safety management system (FrAM) it is demonstrated, how radiation protection (ionizing radiation) can be integrated in a progressive intranet supported management system.

The primary responsibility of the Health, Safety, and Environment (HSE) Division is to provide comprehensive occupational health and safety programs, waste processing, and environment protection. Two supplied-air suits tested for their functional protection were considered to be unacceptable because of low fit factors. Respiratory protective equipment testing for the uS Air Force, Navy, and Army was performed during 1984. The laser aerosol spectrometer (LAS-X) has been shown to operate successfully for measuring and sizing aerosols used for quality assurance testing of high-efficiency particulate air filters used at DOE facilities. Radioanalyses for 239 Pu and 241 Am are presented for the complete skeletal parts of two persons. Air samples from work areas in a coal gasification plant in Yugoslavia show minimal concentration of organic vapors, amines, polynuclear aromatic hydrocarbons, and phenols. Aerosol characteristics of oil shale vapors and manmade vitreous fibers used in ongoing inhalation toxicology studies are presented. Epidemiologic studies of smoking patterns among Los Alamos employees reveal 24.3% smokers compared with the US rate of 32.5%. Environmental surveillance at Los Alamos during 1984 showed the highest estimated radiation dose to an individual at or outside the Laboratory boundary to be about 25% of the natural background radiation dose. Surveillance studies on water and sediment transport of radionuclides, depleted uranium, and silver are described. Bibliographic review of the rooting depth of native plants indicates that even many grass species will root to depths greater than the earth overburden depths to cover low-level radioactive waste sites

Occupational safety and health is one of important issues for workforce movement among ASEAN countries. The objective was to study laws, main agencies, and law enforcement regarding occupational safety and health in Thailand, Indonesia, Malaysia, Philippines, and Singapore. This documentary research covered laws, main agencies' duties, and occupational safety and health law enforcement in Thailand, Indonesia, Malaysia, Philippines, and Singapore. Thailand has its Occupational Safety, Health, and Work EnvironmentAct 2011. Its main agency was Department of Labor Protection and Welfare. Indonesia had WorkSafety Act (Law No. 1, 1970). Its main agency was Department of Manpower and Transmigration. Malaysia had Occupational Safety and Health Act (OSHA) 1994. Its main agency is the Department of Occupational Safety and Health. The Philippines has its Occupational Safety and Health Standards. Its main agency was Department ofLabor and Employment. Singapore has its Workplace Safety and Health Act 2006. Its main agency is Occupational Safety and Health Division. Occupational safety and health law enforcement among each county covers work environment surveillance, workers' health surveillance, advice about prevention and control of occupational health hazards, training and education of employers and employees, data systems, and research. Further in-depth surveys of occupational safety and health among each ASEAN county are needed to develop frameworks for occupational safety and health management for all ASEAN countries.

Environmental and occupational exposures in immigrant health.

Eamranond, Pracha P; Hu, Howard

2008-09-23

Immigrants comprise vulnerable populations that are frequently exposed to a multitude of environmental and occupational hazards. The historical context behind state and federal legislation has helped to foster an environment that is particularly hostile toward caring for immigrant health. Current hazards include toxic exposures, air and noise pollution, motor vehicle accidents, crowded living and work environments with inadequate ventilation, poor sanitation, mechanical injury, among many others. Immigrants lack the appropriate training, materials, health care access, and other resources to reduce their exposure to preventable environmental and occupational health risks. This dilemma is exacerbated by current anti-immigrant sentiments, miscommunication between native and immigrant populations, and legislation denying immigrants access to publicly funded medical care. Given that current health policy has failed to address immigrant health appropriately and political impetus is lacking, efforts should also focus on alternative solutions, including organized labor. Labor unions that serve to educate workers, survey work environments, and defend worker rights will greatly alleviate and prevent the burden of disease incurred by immigrants. The nation's health will benefit from improved regulation of living and workplace environments to improve the health of immigrants, regardless of legal status.

The Workspace Satisfaction Survey measures occupant satisfaction with the thermal, lighting, acoustical, and air quality aspects of the work environment. In addition to ratings of these ambient environmental features, occupants also rate their satisfaction with a number of functional and aesthetic features of the office environment as well as their satisfaction with specific kinds of workspaces (e.g. computer rooms, the lobby, employee lounge, etc.) Each section on ambient conditions includes questions on the frequency with which people experience particular kinds of discomforts or problems, how much the discomfort bothers them, and how much it interferes with their work. Occupants are also asked to identify how they cope with discomfort or environmental problems, and to what extent these behaviors enable them to achieve more satisfactory conditions. This report documents the results of this survey of the occupants of the Eastgate Corporate Center, Bellevue, Washington. 21 figs., 7 tabs.

This document describes interior thermal environment analysis and the techniques involved at three applicable stages of evaluation. They range from the study of plans and archives to physical measurement with sophisticated instrumentation. Environmental factors that influence the thermal state of the building occupant are measured. The occupant's perception of the thermal environment may also be investigated. One of the most important building functions is to isolate the occupants from adverse exterior thermal conditions and provide a productive and healthy interior environment. The thermal environment is determined by clothing level, activity level, air velocity, ambient air temperature, mean radiant temperature and moisture level. Since an optimal thermal environment may not be optimal in terms of the building's energy efficiency, the evaluation process will have to draw upon expertise in energy use and other disciplines at the stage where solutions are recommended. 16 refs., 4 figs., 2 tabs.

Pelegrin, Armando Carballo; Canuet, Leonides; Rodríguez, Ángeles Arias; Morales, Maria Pilar Arévalo

2015-01-01

The purpose of our study was to identify the main factors associated with objective noise-induced hearing loss (NIHL), as indicated by abnormal audiometric testing, in Spanish workers exposed to occupational noise in the construction industry. We carried out a prospective study in Tenerife, Spain, using 150 employees exposed to occupational noise and 150 age-matched controls who were not working in noisy environments. The variables analyzed included sociodemographic data, noise-related factors, types of hearing protection, self-report hearing loss, and auditory-related symptoms (e.g., tinnitus, vertigo). Workers with pathological audiograms had significantly longer noise-exposure duration (16.2 ± 11.4 years) relative to those with normal audiograms (10.2 ± 7.0 years; t = 3.99, P hearing protection measures had audiometric abnormalities (94.1%). Additionally, workers using at least one of the protection devices (earplugs or earmuffs) had significantly more audiometric abnormalities than those using both protection measures simultaneously (Chi square = 16.07; P hearing protection measures [odds ratio (OR) = 12.30, confidence interval (CI) = 4.36-13.81, P hearing protection measures, in particular earplugs and earmuffs, associates with a lower rate of audiometric abnormalities in subjects with high occupational noise exposure. The use of hearing protection measures at work and noise-exposure duration are best predictive factors of NIHL. Auditory-related symptoms and self-report hearing loss do not represent good indicators of objective NIHL. Routine monitoring of noise levels and hearing status are of great importance as part of effective hearing conservation programs.

There is a need for mental health practitioners to understand how inclusive environments that enable participation can be developed. This paper presents the findings from an ethnographic exploration of Mind 'Sprout', a supported community garden situated in inner-city Melbourne. The study explored how this community development project created a socially inclusive environment, and enabled occupational participation among people recovering from mental ill-health. Consistent with the ethos of ethnography, data were collected through participant observation and asking questions of people as they participated at 'Sprout'. Six individual interviews and review of organisational documents were also conducted. Qualitative analysis was used to identify the understandings of how the Sprout community was created and experienced by its members. Three interrelated themes were revealed: Sprout community garden enabled social inclusion and occupational participation by creating community, creating a flexible environment that supports participation and creating a learning environment. The way Sprout operated enabled its members to participate together in occupation and to interact socially within the garden community and beyond as part of the local community. Sprout has developed a philosophy of active participation. The findings point to the opportunities that community development projects offer for creating environments that enable participation and social inclusion. They also suggest that an opportunity exists for occupational therapists to broaden their practise by leading or collaborating in these projects. © 2015 Occupational Therapy Australia.

Nonprice incentives and energy conservation.

In the electricity sector, energy conservation through technological and behavioral change is estimated to have a savings potential of 123 million metric tons of carbon per year, which represents 20% of US household direct emissions in the United States. In this article, we investigate the effectiveness of nonprice information strategies to motivate conservation behavior. We introduce environment and health-based messaging as a behavioral strategy to reduce energy use in the home and promote energy conservation. In a randomized controlled trial with real-time appliance-level energy metering, we find that environment and health-based information strategies, which communicate the environmental and public health externalities of electricity production, such as pounds of pollutants, childhood asthma, and cancer, outperform monetary savings information to drive behavioral change in the home. Environment and health-based information treatments motivated 8% energy savings versus control and were particularly effective on families with children, who achieved up to 19% energy savings. Our results are based on a panel of 3.4 million hourly appliance-level kilowatt-hour observations for 118 residences over 8 mo. We discuss the relative impacts of both cost-savings information and environmental health messaging strategies with residential consumers.

2018-02-01

The percentage of individuals with dementia worldwide is increasing with the continued trend toward global trend overall. As options for the medical treatment of dementia remain limited, combined, non-pharmacological interventions are necessary to maintain and slow the degeneration of functional capabilities. Additionally, there is a need to help caregivers develop better patterns of care and methods to reduce the burden of care. Therefore, occupational therapists play an important role in the dementia care team. This article introduces how occupational therapists help dementia patient maintain their functional capabilities and delay degeneration and help caregivers reduce their burden of care. Both activities are based on the concept of occupational therapy, which includes three important components: people, activities, and the environment.

Over the last decade, influences of the human occupant on indoor chemistry have been investigated in environments ranging from simulated aircraft cabins to actual classrooms. We have learned that ozone reacts rapidly with constituents of skin surface lipids on exposed skin, hair, and clothing...... occupants scavenge ozone, the level of SOA derived from ozone/terpene chemistry decreases; the fraction of SVOCs in the gas-phase increases, and the fraction associated with airborne particles decreases. Occupants also remove organic compounds, including certain chemically active species, via bodily intake....... Studies reviewed in this paper demonstrate the pronounced influences of humans on chemistry within the spaces they inhabit and the consequences of these influences on their subsequent chemical exposures....

Marketing energy conservation options to Northwest manufactured home buyers

1985-06-01

This study relies on extensive, existing survey data and new analyses to develop information that would help design a marketing plan to achieve energy conservation in new manufactured homes. Existing surveys present comprehensive information about regional manufactured home occupants and their homes that are relevant to a potential conservation marketing plan. An independent analysis of the cost-effectiveness of various efficiency improvements provides background information for designing a marketing plan. This analysis focuses on the economic impacts of alternative energy conservation options as perceived by the home owner. Identifying impediments to conservation investments is also very important in designing a marketing plan. A recent report suggests that financial constraints and the need for better information and knowledge about conservation pose the major conservation investment barriers. Since loan interest rates for new manufactured homes typically exceed site-built rates by a considerable amount and the buyers tend to have lower incomes, the economics of manufactured home conservation investments are likely to significantly influence their viability. Conservation information and its presentation directly influences the manufactured home buyer's decision. A marketing plan should address these impediments and their implications very clearly. Dealers express a belief that consumer satisfaction is the major advantage to selling energy efficient manufactured homes. This suggests that targeting dealers in a marketing plan and providing them direct information on consumers' indicated attitudes may be important. 74 refs.

Neotropical coastal lagoons: an appraisal of their biodiversity, functioning, threats and conservation management

Directory of Open Access Journals (Sweden)

FA. Esteves

Full Text Available Neotropical coastal lagoons (NCL are human-dominated ecosystems. Their distribution along densely populated coastal areas of developing countries makes these systems among the most threatened in the world. Here, we summarize some aspects of the causes and consequences of NCL biodiversity, their functioning, their importance to the surrounding populations, their fragility, and their responses to local and global anthropogenic impacts and the challenges that Neotropical countries face in conserving these systems. Although still scarce and geographically concentrated, a growing body of studies has shown that NCLs are physiographically diversified systems, which harbor a considerable and particular proportion of the Neotropical inland aquatic biodiversity. Despite the fact that coastal lagoons are ecotones that are intricately connected to surrounding environments, they develop mechanisms for structural and functional regulation, which confer to these systems higher productivity and carrying capacities than surrounding ecosystems. Such traits attract residential developments and subsidize local traditional populations with important economic and aesthetic ecosystem revenues such as fisheries and scenic beauty. However, the disorganized human occupation around NCLs are causing profound impacts such as eutrophication, salinization, exotic species introduction, as well as other effects, which are ultimately imposing major habitat degradations and biodiversity extirpations in NCLs. We argue that interdisciplinary conservation strategies, which integrate scientific expertise, government officials, private companies and the general public, are the most likely to overcome the geographic and economic obstacles to NCL conservation.

Prevalence of occupational disease

Energy Technology Data Exchange (ETDEWEB)

Newhouse, M.L.

1976-12-01

When discussing the prevalence of occupational disease, both the prescribed diseases and the diseases where occupation has an important etiological component should be considered. Available statistics indicate that there has been a substantial improvement in the control of important prescribed diseases such as lead poisoning and pneumoconiosis. In the United Kingdom in 1900 there were 1000 cases of lead poisoning with 38 fatalities. This number decreased to 49 cases in 1956 when the number again increased due to a change from clinical diagnosis to diagnosis on biochemical evidence. The number of cases of coal workers' pneumoconiosis has declined since the 1950s but the number of coal miners has also been reduced by more than /sup 1///sub 3/. Industrial dermatitis is still a considerable problem. Vibration induced white fingers was mentioned as a disease with a very large occupational component but which for a variety of reasons is not prescribed for industrial injury benefit. Illnesses due to injuries to the back, to sciatica, disc disease or lumbago cause a very large amount of sickness and are often associated with heavy manual labor particularly if an awkward posture has to be adopted for the job. The average absence after a back injury in the London Docks was 61 days. Chronic bronchitis is the biggest single cause of sickness absence. Many studies have shown that the etiology is multifactorial but that hard physical work and a dusty environment in the work place are important adverse factors. Improved control of the working environment and methods of work may influence the development of chronic disease in the older worker.

Program management models have raised concerns among occupational therapists about professional standards related to clinical competence, performance review procedures, and quality improvement initiatives. This paper describes how a chart-stimulated recall (CSR) peer-review process and interview tool was revised, implemented, and evaluated as a pilot project to assess the clinical competence of occupational therapy staff at a large urban health centre in southern Ontario. Fourteen pairs (n=28) of occupational therapists representing various practice areas participated in this project. Half served as peer assessors and half as interviewees. Peer assessors conducted an independent chart review followed by a one-hour personal interview with a peer partner to discuss clinical management issues related to the client cases. Each interviewer rated his or her partner's clinical competence in eight areas of performance using a 7-point Likert scale. Results indicated that the CSR tool could discriminate among occupational therapists in terms of overall levels of clinical competence and also identify specific areas of concern that could be targeted for professional development. Feedback from participants was positive. The CSR tool was found to be useful for assessing clinical competence of occupational therapists in this large health centre as a quality improvement initiative within that discipline group. Further research is needed to establish the reliability and validity of the CSR tool.

The Wallacea Archipelago provides an extraordinary laboratory for the study of human colonisation and adaptation, yet few detailed archaeological studies have been conducted in the region that span the earliest phase of human settlement. Laili Cave, in northern Timor-Leste, preserves the oldest human occupation in this insular region with a cultural sequence spanning 11,200 to 44,600 cal BP. Small-bodied vertebrates and invertebrates were recovered to the lowest excavated levels, associated with highly concentrated stone artefacts. We report on human behavioural adaptations within the context of Pleistocene environments and changing landscapes using zooarchaeological, stone artefact, bathymetric, and experimental isotopic analyses. Results indicate that Pleistocene humans used the abundant local chert liberally and engaged in mobile broad-spectrum exploitation of invertebrates and fishes from marine, estuarine, and freshwater environments within close proximity of Laili Cave. The faunal assemblage indicates heterogeneous but relatively stable environments during the late Pleistocene. Variability in subsistence strategies over time appears to be a response to changing landscapes and concomitant local resources. This record contrasts with marine specialisations evident from other sites in Timor-Leste and within the broader Wallacean region.

Occupational hearing loss is one of the most common work-related illnesses in the United States (US). From 22 to 30 million US workers are exposed to hazardous noise levels at work, and 25% of these workers will develop permanent hearing loss. Hearing loss from noise is slow and painless, and you can have a disability before you notice it. This course presents the hazards associated with workplace noise, the purpose and elements of the Los Alamos National Laboratory (LANL) Hearing Conservation Program (HCP), and controls that are available to reduce your exposure to hazardous levels of noise.

Can a voice disorder be an occupational disease?

Directory of Open Access Journals (Sweden)

Daša Gluvajić

2012-11-01

Full Text Available Voice disorders are all changes in the voice quality that can be detected by hearing. Some etiological factors that contribute to the development of voice disorders are related to occupation, working environment and working conditions. In modern societies one third of the labour force works in professions with vocal loading. In such professions, voice disorders influence work ability and quality of life. For an occupational disease, the exposure to harmful factors in the workplace is essential and causes the development of a disorder in a previously healthy individual. In some European countries, voice disorders in teachers, which do not improve after proper treatment are recognized as occupational diseases. In Slovenia, no organic or functional voice disorder is listed on the current list of occupational diseases. Prevention and cure of occupational voice disorders can contribute to better safety at the workplace and improve the workers’ health. Voice professionals must also know that they are responsible for their own health and that they must actively take care of it.

Occupation, well-being, and culture: Theory and cultural humility.

Science.gov (United States)

Hammell, Karen R Whalley

2013-10-01

The Canadian Model of Occupational Performance and Engagement depicts individuals embedded within cultural environments that afford occupational possibilities. Culture pertains not solely to ethnicity or race but to any dimension of diversity, including class, gender, sexual orientation, and ability. This paper highlights specific dimensions of cultural diversity and their relationships to occupational engagement and well-being. Cultural variations constitute the basis for a socially constructed hierarchy of traits that significantly determine occupational opportunities and impact mental health and well-being. Cultural humility is an approach to redressing power imbalances in client-therapist relationships by incorporating critical self-evaluation and recognizing that cultural differences lie not within clients but within client-therapist relationships. It is proposed that theoretical relevance would be enhanced if culturally diverse perspectives were incorporated into theories of occupation. Cultural humility is advocated as an approach to theoretical development and in efforts to counter professional Eurocentrism, ethnocentrism, and intellectual colonialism.

Graham, John R; Shier, Micheal L; Nicholas, David

2016-06-01

Workplace expectations reflect an important consideration in employee experience. A higher prevalence of workplace congruence between worker and employer expectations has been associated with higher levels of productivity and overall workplace satisfaction across multiple occupational groups. Little research has investigated the relationship between workplace congruence and occupational health outcomes among social service workers. This study sought to better understand the extent to which occupational congruence contributes to occupational outcomes by surveying unionised social service workers ( n = 674) employed with the Government of Alberta, Canada. Multiple regression analysis shows that greater congruence between workplace and worker expectations around workloads, workplace values and the quality of the work environment significantly: (i) decreases symptoms related to distress and secondary traumatic stress; (ii) decreases intentions to leave; and (iii) increases overall life satisfaction. The findings provide some evidence of areas within the workplace of large government run social welfare programmes that can be better aligned to worker expectations to improve occupational outcomes among social service workers.

Occupational stress is a psychosocial dimension of occupational health concept on social determinants of health, especially, job & environmental condition. Recently, staff network of different government universities of Thailand have called higher education commission, and Ministry of Education, Thailand to resolve the issue of government education policy (e.g. wage inequity, poor welfare, law, and job & environment condition) that leads to their job insecurity, physical and mental health problems from occupational stress. The aim of this study was to investigate a causal relationship of occupational stress among the academic university employees. This cross sectional research was conducted in 2014 among 2,000 academic university employees at Thai government universities using stratified random sampling. Independent variables were wage, family support, periods of duty, and job & environmental condition. Dependent variable was stress. Job & environmental condition, as social and environmental factor, and periods of duty as individual factor had direct effect to stress (Pstress (P occupational stress among academic university employees at moderate level.

Full Text Available The purpose of this study is to describe the role of occupational therapy fieldwork students in the training of service dogs. Ethnography is an approach that strives to explore and describe the point of view of people. Ethnographers view the researcher as an instrument to gain insight into the subject. This researcher utilizedher own experiences as an occupational therapist, an occupational therapy educator, and as a volunteer dog trainer of service dogs. She then validated the process through interviews with key informants. The results indicate that occupational therapists and occupational therapy students are capable of playing a significantrole in the training and placement of service dogs. During a level I experience, occupational therapy students experienced the importance that a dog can play in a person’s life as a tool of adaptation. They also learned advocacy and professionalism and applied the Person-Environment-Occupation model of practice. In addition, students recognized that barriers exist in the use of service dogs.

Occupational ocular trauma is an important cause of acquired monocular blindness in a rapidly industrialising country like India. Knowledge of the epidemiology of occupational eye injuries is essential to formulate viable industrial safety measures. We retrospectively reviewed all patients with occupational open globe injuries between 1994 and 1998. We documented the circumstances of the injuries, their clinical findings and the use of appropriate protective eyewear at the time of the injury. The visual acuity 6 months after the injury was the final outcome measure. In this study period we examined 43 patients with open globe injuries sustained at the work place. Thirty-four (79.1%) patients were young males. The iron and steel industry accounted for 19 (44.2%) cases while 8 (18.6%) patients each were from the agricultural, mining and other small scale industrial sectors. At the time of the injury, 33 (76.7%) were not wearing the recommended protective eyewear and 6 (13.9%) were under the influence of alcohol. The injuries were mild in 6 (13.9%), moderate in 18 (41.9%) and severe in 19 (44.2%) patients. At the end of 6 months, 2 (4.7%) patients had a visual acuity of 6/12 or better, 4 (9.3%) had a visual acuity of 6/18 to 6/60 and 29 (67.4.%) had a vision of eyewear and alcohol-free environment at the work place is likely to reduce the incidence of severe occupational open globe injuries.

Engineered Solutions to Reduce Occupational Noise Exposure at the NASA Glenn Research Center: A Five-Year Progress Summary (1994-1999)

Cooper, Beth A.; Hange, Donald W.; Mikulic, John J.

1999-01-01

At the NASA John H. Glenn Research Center at Lewis Field (formerly the Lewis Research Center), experimental research in aircraft and space propulsion systems is conducted in more than 100 test cells and laboratories. These facilities are supported by a central process air system that supplies high-volume, high-pressure compressed air and vacuum at various conditions that simulate altitude flight. Nearly 100,000 square feet of metalworking and specialized fabrication shops located on-site produce prototypes, models, and test hardware in support of experimental research operations. These activities, comprising numerous individual noise sources and operational scenarios, result in a varied and complex noise exposure environment, which is the responsibility of the Glenn Research Center Noise Exposure Management Program. Hearing conservation, community noise complaint response and noise control engineering services are included under the umbrella of this Program, which encompasses the Occupational Safety and Health Administration (OSHA) standard on occupational noise exposure, Sec. 29CFR 1910.95, as well as the more stringent NASA Health Standard on Hearing Conservation. Prior to 1994, in the absence of feasible engineering controls, strong emphasis had been placed on personal hearing protection as the primary mechanism for assuring compliance with Sec. 29CFR 1910.95 as well as NASA's more conservative policy, which prohibits unprotected exposure to noise levels above 85 dB(A). Center policy and prudent engineering practice required, however, that these efforts be extended to engineered noise controls in order to bring existing work areas into compliance with Sec. 29CFR 1910.95 and NASA's own policies and to ensure compliance for new installations. Coincident with the establishment in 1995 of a NASA wide multi-year commitment of funding for environmental abatement projects, the Noise Exposure Management Program was established, with its focus on engineering approaches

The recognition of occupational carcinogens is important for primary prevention, compensation and surveillance of exposed workers, as well as identifying causes of cancer in the general population. This study updates previously published lists of known occupational carcinogens while providing additional information on cancer type, exposure scenarios and routes, and discussing trends in the identification of carcinogens over time. Data were extracted from International Agency for Research on Cancer (IARC) Monographs covering the years 1971-2017, using specific criteria to ensure occupational relevance and provide high confidence in the causality of observed exposure-disease associations. Selected agents were substances, mixtures or types of radiation classified in IARC Group 1 with 'sufficient evidence of carcinogenicity' in humans from studies of exposed workers and evidence of occupational exposure documented in the pertinent monograph. The number of known occupational carcinogens has increased over time: 47 agents were identified as known occupational carcinogens in 2017 compared with 28 in 2004. These estimates are conservative and likely underestimate the number of carcinogenic agents present in workplaces. Exposure to these agents causes a wide range of cancers; cancers of the lung and other respiratory sites, followed by skin, account for the largest proportion. The dominant routes of exposure are inhalation and dermal contact. Important progress has been made in identifying occupational carcinogens; nevertheless, there is an ongoing need for research on the causes of work-related cancer. Most workplace exposures have not been evaluated for their carcinogenic potential due to inadequate epidemiologic evidence and a paucity of quantitative exposure data. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Smart building temperature control using occupant feedback

Science.gov (United States)

Gupta, Santosh K.

feedback signals, we propose a distributed solution, which ensures that a consensus is attained among all occupants upon convergence, irrespective of their temperature preferences being in coherence or conflicting. Occupants are only assumed to be rational, in that they choose their own temperature set-points so as to minimize their individual energy cost plus discomfort. We use Alternating Direction Method of Multipliers ( ADMM) to solve our consensus problem. We further establish the convergence of the proposed algorithm to the optimal thermal set point values that minimize the sum of the energy cost and the aggregate discomfort of all occupants in a multi-zone building. For simulating our consensus algorithm we use realistic building parameters based on the Watervliet test facility. The simulation study based on real world building parameters establish the validity of our theoretical model and provide insights on the dynamics of the system with a mobile user population. In the third part we present a game-theoretic (auction) mechanism, that requires occupants to "purchase" their individualized comfort levels beyond what is provided by default by the building operator. The comfort pricing policy, derived as an extension of Vickrey-Clarke-Groves (VCG) pricing, ensures incentive-compatibility of the mechanism, i.e., an occupant acting in self-interest cannot benefit from declaring their comfort function untruthfully, irrespective of the choices made by other occupants. The declared (or estimated) occupant comfort ranges (functions) are then utilized by the building operator---along with the energy cost information---to set the environment controls to optimally balance the aggregate discomfort of the occupants and the energy cost of the building operator. We use realistic building model and parameters based on our test facility to demonstrate the convergence of the actual temperatures in different zones to the desired temperatures, and provide insight to the pricing

Occupational injuries have considerable impact on workers' lives. However, data regarding workers' health-related quality of life (HRQOL) at several years after the injury are lacking. This study assessed workers' HRQOL at 6 years after occupational injury and determined related factors in each HRQOL domain. Workers who sustained an occupational injury in 2009 and who responded to a previous survey at 3 or 12 months after their injury were followed up in 2015. A total of 1715 participants were candidates for this study. The Taiwanese version of the World Health Organization Quality of Life scale-abbreviated version (WHOQOL-BREF) was used to assess their HRQOL. Multiple linear regression analysis identified predictive factors for HRQOL at 6 years after occupational injury. A total of 563 workers completed the questionnaire (response rate, 32.8%). Adverse life events and additional severe occupational injuries that occurred within the follow-up period, and decreased salary after the injury were significant factors for low scores in all domains of the WHOQOL-BREF. In addition, unmarried participants had low scores in the social relationship domain. Workers with family members requiring care scored low in the physical and environment domains. Workers whose injuries had major effects on their physical appearance had low scores in the physical and psychological domains. Workers with unstable employment had low scores in physical, psychological, and environment domains. At 6 years after occupational injury, workers' HRQOL was poor among those whose salaries decreased after the injury, after adjustment for other factors.

Conservation implications of anthropogenic impacts on visual communication and camouflage.

Science.gov (United States)

Delhey, Kaspar; Peters, Anne

2017-02-01

Anthropogenic environmental impacts can disrupt the sensory environment of animals and affect important processes from mate choice to predator avoidance. Currently, these effects are best understood for auditory and chemosensory modalities, and recent reviews highlight their importance for conservation. We examined how anthropogenic changes to the visual environment (ambient light, transmission, and backgrounds) affect visual communication and camouflage and considered the implications of these effects for conservation. Human changes to the visual environment can increase predation risk by affecting camouflage effectiveness, lead to maladaptive patterns of mate choice, and disrupt mutualistic interactions between pollinators and plants. Implications for conservation are particularly evident for disrupted camouflage due to its tight links with survival. The conservation importance of impaired visual communication is less documented. The effects of anthropogenic changes on visual communication and camouflage may be severe when they affect critical processes such as pollination or species recognition. However, when impaired mate choice does not lead to hybridization, the conservation consequences are less clear. We suggest that the demographic effects of human impacts on visual communication and camouflage will be particularly strong when human-induced modifications to the visual environment are evolutionarily novel (i.e., very different from natural variation); affected species and populations have low levels of intraspecific (genotypic and phenotypic) variation and behavioral, sensory, or physiological plasticity; and the processes affected are directly related to survival (camouflage), species recognition, or number of offspring produced, rather than offspring quality or attractiveness. Our findings suggest that anthropogenic effects on the visual environment may be of similar importance relative to conservation as anthropogenic effects on other sensory modalities

Feedbacks between conservation and social-ecological systems

Miller, Brian W.; Caplow, Susan C.; Leslie, Paul W.

2012-01-01

Robust ways to meet objectives of environmental conservation and social and economic development remain elusive. This struggle may in part be related to insufficient understanding of the feedbacks between conservation initiatives and social-ecological systems, specifically, the ways in which conservation initiatives result in social changes that have secondary effects on the environments targeted by conservation. To explore this idea we sampled peer-reviewed articles addressing the social and environmental dimensions of conservation and coded each paper according to its research focus and characterization of these feedbacks. The majority of articles in our sample focused either on the effect of conservation initiatives on people (e.g., relocation, employment) or the effect of people on the environment (e.g., fragmentation, conservation efficacy of traditional management systems). Few studies in our sample empirically addressed both the social dynamics resulting from conservation initiatives and subsequent environmental effects. In many cases, one was measured and the other was discussed anecdotally. Among the studies that describe feedbacks between social and environmental variables, there was more evidence of positive (amplifying) feedbacks between social and environmental outcomes (i.e., undesirable social outcomes yielded undesirable environmental effects, and desirable social outcomes yielded desirable environmental effects). The major themes within the sampled literature include conflict between humans and wild animals, social movements, adaptive comanagement, loss of traditional management systems, traditional ecological knowledge, human displacement and risks to livelihoods, and conservation and development. The narratives associated with each theme can serve as hypotheses for facilitating further discussion about conservation issues and for catalyzing future studies of the feedbacks between conservation and social-ecological systems.

Occupational emerging risks affecting international virtual project Team Results

Directory of Open Access Journals (Sweden)

Dumitraşcu-Băldău Iulia

2017-01-01

Full Text Available The expansion of internet access, high-speed connection services, collaborative work platforms and tools, allowed employees to interact virtually offering companies the possibility to develop projects around the world, reducing operational costs and gain competitive advantage. Realizing the advantages and disadvantages of developing a project team in an international virtual work environment, requires adopting specific strategies to construct an effective team and ensure the project success. One of the most important disadvantages that we identified is that the new work environment brings new risks for both team members and managers. So, it becomes mandatory to identify and analyze the occupational emerging risks and their impact on the productivity of virtual team members, in order to prevent them efficiently and to ensure the safety and health of employees in a virtual working environment. This paper aims to highlight the necessity for project managers and organizations, to include in their specific project strategies, an efficient occupational risks management in the virtual workplace, to obtain a continuously improved virtual working environment, so to achieve a high performance from virtual employees.

Is international conservation aid enough?

Science.gov (United States)

Law, Elizabeth A.

2016-02-01

Bare et al (2015 Environ. Res. Lett. 10 125010) ask an important question: is international conservation enough? Since the 1990’s international conservation donors have spent over 3.4 billion on biodiversity conservation related projects in sub-Saharan Africa. Both donors and recipients have a right to know if this is effective. Surprisingly, this question is rarely asked. It is a difficult question—involving many rival social, environmental, and economic explanations. Bare, Kauffman and Miller uncover some interesting associations, supporting existing hypotheses and proposing their own: that conservation aid alone is insufficient to mitigate drivers of deforestation (and in some cases may even exacerbate forest loss). This controversial result warrants further investigation—but what is needed now is nuance and robustness in further analyses, to have more confidence in the critique and it’s implications for international conservation aid.

This article reports on a literature review of workplace interventions (i.e., creating healthy work environments and improving nurses' quality of work life [QWL]) aimed at managing occupational stress and burnout for nurses. A literature search was conducted using the keywords nursing, nurses, stress, distress, stress management, burnout, and intervention. All the intervention studies included in this review reported on workplace intervention strategies, mainly individual stress management and burnout interventions. Recommendations are provided to improve nurses' QWL in health care organizations through workplace health promotion programs so that nurses can be recruited and retained in rural and northern regions of Ontario. These regions have unique human resources needs due to the shortage of nurses working in primary care. © 2015 The Author(s).

Managing dysphonia in occupational voice users.

Behlau, Mara; Zambon, Fabiana; Madazio, Glaucya

2014-06-01

Recent advances with regard to occupational voice disorders are highlighted with emphasis on issues warranting consideration when assessing, training, and treating professional voice users. Findings include the many particularities between the various categories of professional voice users, the concept that the environment plays a major role in occupational voice disorders, and that biopsychosocial influences should be analyzed on an individual basis. Assessment via self-evaluation protocols to quantify the impact of these disorders is mandatory as a component of an evaluation and to document treatment outcomes. Discomfort or odynophonia has evolved as a critical symptom in this population. Clinical trials are limited and the complexity of the environment may be a limitation in experiment design. This review reinforced the need for large population studies of professional voice users; new data highlighted important factors specific to each group of voice users. Interventions directed at student teachers are necessities to not only improving the quality of future professionals, but also to avoid the frustration and limitations associated with chronic voice problems. The causative relationship between the work environment and voice disorders has not yet been established. Randomized controlled trials are lacking and must be a focus to enhance treatment paradigms for this population.

Hocking, Clare; Kroksmark, Ulla

2013-03-01

Abstract Occupational therapists and occupational scientists are increasingly aware of the relationship between occupation and global climate change, with some working to raise awareness of the issues and others proposing that an occupational perspective can make a valuable contribution to understanding and addressing the issues. In this discussion paper the United Nations Global Survey on Sustainable Lifestyles ( 1 ), which reports young adults' beliefs about everyday occupations that have a substantial impact on the environment (food, housekeeping, and transportation) is introduced. The authors argue that the survey findings are a valuable resource for occupational therapists who are concerned about global climate change and work with young adults (age 18-35), providing valuable insights into their concerns and preferences in relation to sustainability. To illustrate the insights contained in the reports, findings from four countries are presented: New Zealand and Sweden, the authors' countries of origin, and the Philippines and Lebanon which have people living in New Zealand and Sweden. Application to individual and community-based interventions to promote more sustainable lifestyles is suggested, along with studies to examine the perspectives of young adults with a disability, as their concerns and sustainability preferences might differ due to the barriers that limit their participation in educational and vocational occupations.

Instead, such an environment will incur higher energy costs and produce greater CO2 emissions. Furthermore, this may lead to the degeneration of occupants' inherent ability to combat thermal stress, thereby weakening thermal adaptability. Measured data from many field investigations have shown that the human body has a higher acceptance to the thermal environment in free-running buildings than to that in air-conditioned buildings with similar average parameters. In naturally ventilated environments, occupants have reported superior thermal comfort votes and much greater thermal comfort temperature ranges compared to air-conditioned environments. This phenomenon is an integral part of the adaptive thermal comfort model. In addition, climate chamber experiments have proven that people prefer natural wind to mechanical wind in warm conditions; in other words, dynamic airflow can provide a superior cooling effect. However, these findings also indicate that significant questions related to thermal comfort remain unanswered. For example, what is the cause of these phenomena? How we can build a comfortable and healthy indoor environment for human beings? This article summarizes a series of research achievements in recent decades, tries to address some of these unanswered questions, and attempts to summarize certain problems for future research. © 2015 John Wiley & Sons A/S.

Liedberg, Gunilla M; Björk, Mathilda; Hensing, Gunnel

2010-10-01

Women and men are shaped over the courses of their lives by culture, society and human interaction according to the gender system. Cultural influences on individuals' social roles and environment are described in occupational therapy literature, but not specifically from a gender perspective. The purpose of this qualitative study was to explore how a sample of occupational therapists perceives the 'gender' concept. Four focus group interviews with 17 occupational therapists were conducted. The opening question was: 'How do you reflect on the encounter with a client depending on whether it is a man or a woman?' The transcribed interviews were analysed and two main themes emerged: 'the concept of gender is tacit in occupational therapy' and 'client encounters'. The occupational therapists expressed limited theoretical knowledge of 'gender'. Furthermore, the occupational therapists seemed to be 'doing gender' in their encounters with the clients. For example, in their assessment of the client, they focussed their questions on different spheres: with female clients, on the household and family; with male clients, on their paid work. This study demonstrated that occupational therapists were unaware of the possibility that they were 'doing gender' in their encounters with clients. There is a need to increase occupational therapists' awareness of their own behaviour of 'doing gender'. Furthermore, there is a need to investigate whether gendered perceptions will shorten or lengthen a rehabilitation period and affect the chosen interventions, and in the end, the outcome for the clients. © 2010 The Authors.

It has been observed that the construction industry is one of the notorious industry having higher rate of facilities and injuries. Resulting in higher financial losses and work hour losses, which are normally faced by this industry due to occupational accidents. Construction industry has the highest occupational accidents rate recorded throughout the world after agriculture industry. The construction work site is often a busy place having an incredibly high account of activities taking place, where everyone is moving in frenzy having particular task assigned. In such an environment, occupational accidents do occur. This paper gives information about different types of occupational accidents and their causes in the construction industry of Pakistan. A survey has been carried out to identify the types of occupational accidents often occur at construction site. The impact of each occupational accident has also been identified. The input from the different stakeholders involved on the work site was analyzed using RIW (Relative Importance Weight) method. The findings of this research show that fall from elevation, electrocution from building power and snake bite are the frequent occupational accidents occur within the work site where as fall from elevation, struck by, snake bite and electrocution from faulty tool are the occupational accident with high impact within the construction industry of Pakistan. The results also shows the final ranking of the accidents based on higher frequency and higher impact. Poor Management, Human Element and Poor Site Condition are found as the root causes leading to such occupational accidents. Hence, this paper identify that what type of occupational accidents occur at the work place in construction industry of pakistan, in order to develop the corrective actions which should be adequate enough to prevent the re-occurrence of such accidents at work site.

Full Text Available The opinions and perceptions of local communities are central issues in the sustainable management of conservation areas. During 2002 and 2003, we studied the opinions of local people about nature conservation and the development of tourism to investigate whether these opinions were influenced by socioeconomic and demographic factors. Data were collected via a survey of local residents in six areas with different histories of land use, land ownership, conservation, and tourism development. We classified respondents by cluster analysis into three different groups according to their opinions about nature conservation and tourism development: (1 sympathetic to nature conservation, but quite neutral to tourism development (57.7%; (2 critical of nature conservation, but quite neutral to tourism development (30.5%; and (3 quite neutral to nature conservation, but critical of tourism development (11.8%. The most important factors for classification were residential area, age, level of education, primary occupation, indigenousness, frequency of contact with tourists through work, and effects of nature conservation on household economy. On the other hand, gender, level of income, land ownership, land donation for conservation, and income from tourism did not affect opinions concerning nature conservation and tourism development. Almost equal proportions of residents living in close proximity to conservation areas in Kuusamo had positive and negative opinions about nature conservation. Residents living in close proximity to conservation areas regarded conservation as something that might reduce employment and incomes. On the other hand, a greater proportion of residents living near tourist resorts and farther from conservation areas had positive opinions about and perceptions of nature conservation and tourism development. Based on the proportional division of all respondents into the three groups, there may be a coexistent relationship between nature

Full Text Available Increased noise, which is also below the occupational exposure values and is “hearing safe” noise, affects the exposed person’s health as a non-specific stressor. Increased noise level also creates an environment for additional vocal apparatus load. The objective of this study was to determine preschool personnel occupational noise and its relationship with subjective health complaints. Data were obtained with survey assistance through subjective answers of respondents about health complaints and noise exposure among Rīga preschool personnel. Objective noise measurements were made to assess real noise levels in the preschool environment. Data from 155 respondents and objective measurements of 37 preschool classrooms were obtained. The results showed that the average 8-h noise exposure among Rīga preschool educational institutions was 70 dB(A, which did not exceed the Latvian work environment noise limits, but exceeded the 35–40 dB(A noise limit in the educational environment guidelines recommended by the WHO. The survey results showed that loud noise is one of the most important workplace environmental factors (~70% of respondents feel a necessity to increase voice because of noise. A constant feeling of fatigue, headache, irritable feeling, and a desire to isolate oneself from others more often occurred in respondents exposed to increased noise, compared with those who noted that they were not exposed to increased noise. In general, loud noise was associated with increased subjective health complaints in preschool education institution personnel.

Objective: To investigate the cause of occupational exposure among 136 nurses in a tertiary infectious disease hospital, and puts forward the prevention strategy. Methods: A total of 136 nurses exposed to occupational exposure between 2014 and 2016 were included in the study. Analysis was conducted from the years of work of nurses, exposure routes, and the pathogens. Results: The nurses suffer from the highest risk of occupational exposures (73.91%) .Nurses working for less than 5 years and interns are most likely to suffer occupational exposure (45.59% and 35.29% respectively) . Occupational exposure was mainly caused by needle injuries, in which infusion was the main route of occupational exposure (36.76%) . The improper treatment of needle pulling after infusion is the main link of needle puncture (36.76%) . Occupational exposure pathogens were mainly HBV (63.24%) . Conclusion: Nursing staff is the high-risk group of occupational exposure. Irregular operation, lack of awareness of protection, improper disposal after the needle withdrawal and poor safety assessment of the operating environment are the main causes of occupational exposure. It is suggested to strengthen the training of occupational safety and protection, enhance clinical nurses occupational safety protection consciousness, standardize medical operation, so as to prevent the occurrence of occupational exposure.

2018-01-01

Crayfish use of intermittent streams is especially important to understand in the face of global climate change. We examined the influence of stream permanence and local habitat on crayfish occupancy and species densities in the Ozark Highlands, USA. We sampled in June and July 2014 and 2015. We used a quantitative kick–seine method to sample crayfish presence and abundance at 20 stream sites with 32 surveys/site in the Upper White River drainage, and we measured associated local environmental variables each year. We modeled site occupancy and detection probabilities with the software PRESENCE, and we used multiple linear regressions to identify relationships between crayfish species densities and environmental variables. Occupancy of all crayfish species was related to stream permanence. Faxonius meeki was found exclusively in intermittent streams, whereas Faxonius neglectus and Faxonius luteushad higher occupancy and detection probability in permanent than in intermittent streams, and Faxonius williamsi was associated with intermittent streams. Estimates of detection probability ranged from 0.56 to 1, which is high relative to values found by other investigators. With the exception of F. williamsi, species densities were largely related to stream permanence rather than local habitat. Species densities did not differ by year, but total crayfish densities were significantly lower in 2015 than 2014. Increased precipitation and discharge in 2015 probably led to the lower crayfish densities observed during this year. Our study demonstrates that crayfish distribution and abundance is strongly influenced by stream permanence. Some species, including those of conservation concern (i.e., F. williamsi, F. meeki), appear dependent on intermittent streams, and conservation efforts should include consideration of intermittent streams as an important component of freshwater biodiversity.

The effect of occupational meaningfulness on occupational commitment

Directory of Open Access Journals (Sweden)

Itai Ivtzan

2014-11-01

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

Limited information is available on occupational exposures during routine, nonoutage work activities in coal-fueled power plants. This study evaluated occupational exposures to the principal contaminants in the facilities, including respirable dust (coal dust), arsenic, noise, asbestos, and heat stress. The data were collected over a 3-month period, during the summer of 2001. Each of the 5 facilities was divided into 5 similar exposure groups based on previous exposure assessments and job tasks performed. Of the nearly 400 air samples collected, only 1 exceeded the allowable occupational exposure value. For the noise samples, 55 (about 18%) were equal to or greater than the Occupational Safety and Health Administration (OSHA) 8-hour hearing conservation program level of 85 dBA, and 12 (about 4%) were equal to or greater than the OSHA 8-hour permissible exposure level of 90 dBA. Heat stress monitoring at the facilities indicates that 26% of the 1-hour TWAs were exceeded for one or all of the recommended heat stress limits. The data also concluded that some work sites were above the heat stress ceiling values recommended by the National Institute for Occupational Safety and Health (NIOSH). Four of the 20 employees personally monitored exceeded the recommended limits for heart rate or body core temperature. This suggests there is a potential for heat strain if signs and symptoms are ignored. Recommendations are made to better control the heat stress exposure.

This study evaluated occupational exposures to the principal contaminants in the facilities, including respirable dust (coal dust), arsenic, noise, asbestos, and heat stress. The data were collected over a 3-month period, during the summer of 2001, in 5 representative power plants of a large southeastern power-generating company. From 4 of the 5 facilities, 392 air samples and 302 noise samples were collected with approximately 50 respirable coal dust, 32 arsenic, 15 asbestos, and 70 noise samples from each of the 4 plants. One of the previously surveyed facilities was also evaluated for heat stress, and 1 additional coal-fueled power plant was surveyed for a total of 20 personal heat stress samples. Of the nearly 400 air samples collected, only 1 exceeded the allowable occupational exposure value. For the noise samples, 55 were equal to or greater than the Occupational Safety and Health Administration (OSHA) 8-hour hearing conservation program level of 85 dBA, and 12 were equal to or greater than the OSHA 8-hour permissible exposure level of 90 dBA.

This study was conducted to assess occupational stress and strain in primary and secondary school teachers. A test of occupational stress and strain was carried out by using Occupational Stress Inventory Revised Edition (OSI-R) in 1460 primary and secondary school teachers (teacher group) and 319 mental workers in non-educational area (non-teacher group as control). The results showed the level of occupational stress in role overload and physical environment in the teacher group was significantly higher than that in the non-teacher group (P < 0.05). In teacher group the level of occupational stress and strain increased with age; the occupational stress and strain in male teachers were significantly higher than those in female teachers (P < 0.01); the occupational stress and strain in secondary school teachers were significantly higher than those in primary school teachers. These results indicate: to protect and promote primary and secondary school teacher's health, particularly male teachers' health, to mitigate their work pressure and to raise the quality of education are important tasks in the area of occupational health.

In Japan, an employer of a workplace with 50 or more employees is legally required to assign an occupational health physician. The assignment rate in 2010 was reported as 87.0%. This policy started with the provision of "factory physician"in the Factory Law in 1938, then the Labour Standard Law stipulated "physician hygienist" in 1947, and finally the Industrial Safety and Health Law defined "occupational health physician" in 1972. In 1996, a revision of the law then required those physicians to complete training courses in occupational medicine, as designated by an ordinance. Historically, an on-site physician was expected to cure injuries and to prevent communicable diseases of factory workers. The means of occupational hygienic management by working environment measurements, etc., and of health management by health examinations, etc., were developed. Localized exhaust ventilation and personal protection equipment became widely utilized. Qualification systems for non-medical experts in occupational hygiene were structured, and relationships between employers and occupational health physicians were stipulated in the legislative documents. Currently, the Japan Medical Association and the University of Occupational and Environmental Health, Japan educate and train occupational health physicians, and the Japan Society for Occupational Health maintains a specialized board certification system for these physicians. In the future, additional efforts should be made to strengthen the expertise of occupational health physicians, to define and recognize the roles of non-medical experts in occupational hygiene, to incorporate occupational health services in small enterprises, to promote occupational health risk assessment in the workplace, and to reorganize the current legislation, amended repeatedly over the decades.

Occupational stress in the multicultural workplace.

Pasca, Romana; Wagner, Shannon L

2011-08-01

Occupational stress is a well researched topic leading to the development of strong, viable models of workplace stress. However, there is a gap in the literature with respect to the applicability of this research to specific cultural groups, in particular those of immigrant status. The present paper reviews the extant literature regarding occupational stress from a multicultural perspective, evaluates the usefulness for existing models in the multicultural context, and discusses current issues with respect to increasing multiculturalism in the work environment. The authors conclude that workforce diversity is emerging as a pressing issue of organizational life and consequently, that future research needs to continue investigating whether current knowledge regarding workplace stress is fitting with the multicultural diversity of the present-day working population.

, a significantassociation was found for those with anxiety disorders; the odds ratios (OR) were significantly higher the greater the total KOSS-SF score (moderate-risk group OR=2.85, 95 % CI=1.79-4.56; high-risk group OR=5.34, 95 % CI=3.59-7.96). In addition, excluding insufficient job control, all other KOSS-SF subscales were significantly associated with anxiety symptoms, and a relatively high OR was seen in the high-risk group for job demand (OR=3.19, 95 % CI=2.27-4.49), job insecurity (OR=4.52, 95 % CI=2.86-7.13), and occupational culture (OR=4.52, 95 % CI=2.90-7.04). There was a significant association between anxiety symptoms and occupational stress stemming from the psychosocial work environment among these South Korean female manufacturing workers. Future longitudinal studies are needed to examine the association between the occupational stress caused by the psychosocial work environment and the incidence of anxiety disorders and anxiety symptoms. Furthermore, intervention programs that aim to address the prevalence of anxiety symptoms and improve the psychosocial work environment, especially for younger female manufacturing workers, are needed.

Rules and recent trends for setting health-based occupational exposure limits for chemicals

Full Text Available The working environment is the special case of the non-natural environment created by man in which the increased production activity brings about the concentration of stimulators particularly aggressive to the human organism, such as chemical hazards, noise, vibration, extreme temperatures, and finally, intensified psychological and emotional stress. Depending on the nature and intensity, working environment factors have been classified into dangerous, harmful and annoying. The workers are more and more frequently exposed to dangerous chemicals in the working environment. The chemicals cause many diseases including, in the 1st place, respiratory insufficiency, inflammatory skin conditions, psychoneurological disorders and neoplastic diseases. Occupational exposure limit values (OELs, the main criteria for occupational exposure assessment, constitute an important factor for the safe use of chemicals in the working environment. In Poland, to date there are 524 chemical substances and 19 dusts for which maximum admissible concentrations (MAC have been established.

A guide to calculating habitat-quality metrics to inform conservation of highly mobile species

Many metrics exist for quantifying the relative value of habitats and pathways used by highly mobile species. Properly selecting and applying such metrics requires substantial background in mathematics and understanding the relevant management arena. To address this multidimensional challenge, we demonstrate and compare three measurements of habitat quality: graph-, occupancy-, and demographic-based metrics. Each metric provides insights into system dynamics, at the expense of increasing amounts and complexity of data and models. Our descriptions and comparisons of diverse habitat-quality metrics provide means for practitioners to overcome the modeling challenges associated with management or conservation of such highly mobile species. Whereas previous guidance for applying habitat-quality metrics has been scattered in diversified tracks of literature, we have brought this information together into an approachable format including accessible descriptions and a modeling case study for a typical example that conservation professionals can adapt for their own decision contexts and focal populations.Considerations for Resource ManagersManagement objectives, proposed actions, data availability and quality, and model assumptions are all relevant considerations when applying and interpreting habitat-quality metrics.Graph-based metrics answer questions related to habitat centrality and connectivity, are suitable for populations with any movement pattern, quantify basic spatial and temporal patterns of occupancy and movement, and require the least data.Occupancy-based metrics answer questions about likelihood of persistence or colonization, are suitable for populations that undergo localized extinctions, quantify spatial and temporal patterns of occupancy and movement, and require a moderate amount of data.Demographic-based metrics answer questions about relative or absolute population size, are suitable for populations with any movement pattern, quantify demographic

To assess occupational stress and quality of working life (QWL) and their association in workers with different jobs. The Occupational Stress Inventory Revised Edition (OSI-R) and Quality of Working Life Scale (QWL7-32) were administered to 194 workers in the Liaohe Oilfield. The association between occupational stress and quality of working life was analysed by controlling job types and other confounding variables. Office workers had significantly lower scores in occupational role questionnaire (ORQ) and personal strain questionnaire (PSQ) and higher scores in personal resources questionnaire (PRQ) and QWL than physical laborers (P<0.05). The PSQ scores were positively correlated with the ORQ scores and negatively correlated with the PRQ scores. The QWL scores were negatively correlated with the ORQ and PSQ scores, and positively correlated with the PRQ scores (P<0.001). The QWL scores changed with job types. The QWL scores declined with the increase of stress levels (P<0.01). ORQ, role boundary (RB), role insufficiency (RI), physical environment (PE), PSQ, vocational strain (VS), interpersonal strain (IS) and PRQ had a significant impact on quality of working life (P<0.01). Occupational stress is associated with quality of working life. Quality of working life can be improved through control of occupational stress.

The Maslach Burnout Inventory-General Survey (MBI-GS) was used to identify job burnout. The occupation stress inventory revised edition (OSI-R) was used to evaluate the level of occupational stress. Surgeon and doctors working in the internal medicine wards scored significantly higher in job burnout than their colleagues (P < 0.05). The 30-40 years of age group scored highest in exhaustion. The score of professional efficacy decreased with age and increased with educational levels. Role overload, responsibility, physical environment, reaction and self-care were major predictors for exhaustion. Role insufficiency, role overload and responsibility were major predictors for cynicism. Role insufficiency, social support and rational/cognitive were major predictors for professional efficacy. Maintaining moderate professional duty and responsibility, clearly defining job requirements, enriching leisure activities, and improving self-care ability are important measures to preventing job burnout.

Landscape and Local Controls of Insect Biodiversity in Conservation Grasslands: Implications for the Conservation of Ecosystem Service Providers in Agricultural Environments

Full Text Available The conservation of biodiversity in intensively managed agricultural landscapes depends on the amount and spatial arrangement of cultivated and natural lands. Conservation incentives that create semi-natural grasslands may increase the biodiversity of beneficial insects and their associated ecosystem services, such as pollination and the regulation of insect pests, but the effectiveness of these incentives for insect conservation are poorly known, especially in North America. We studied the variation in species richness, composition, and functional-group abundances of bees and predatory beetles in conservation grasslands surrounded by intensively managed agriculture in Southwest Ohio, USA. Characteristics of grassland patches and surrounding land-cover types were used to predict insect species richness, composition, and functional-group abundance using linear models and multivariate ordinations. Bee species richness was positively influenced by forb cover and beetle richness was positively related to grass cover; both taxa had greater richness in grasslands surrounded by larger amounts of semi-natural land cover. Functional groups of bees and predatory beetles defined by body size and sociality varied in their abundance according to differences in plant composition of grassland patches, as well as the surrounding land-cover diversity. Intensive agriculture in the surrounding landscape acted as a filter to both bee and beetle species composition in conservation grasslands. Our results support the need for management incentives to consider landscape-level processes in the conservation of biodiversity and ecosystem services.

The West Valley Nuclear Services Co. LLC (WVNS) is committed to provide a safe, clean, working environment for employees, and to implement U.S. Department of Energy (DOE) requirements affecting worker safety. The West Valley Demonstration Project (WVDP) Occupational Safety and Health Program is designed to protect the safety, health, and well-being of WVDP employees by identifying, evaluating, and controlling biological, chemical, and physical hazards in the work place. Hazards are controlled within the requirements set forth in the reference section at the end of this report. It is the intent of the WVDP Occupational Safety and Health Program to assure that each employee is provided with a safe and healthy work environment. This report shows the logical path toward ensuring employee safety in planning work at the WVDP. In general, planning work to be performed safely includes: combining requirements from specific programs such as occupational safety, industrial hygiene, radiological control, nuclear safety, fire safety, environmental protection, etc.; including WVDP employees in the safety decision-making processes; pre-planning using safety support re-sources; and integrating the safety processes into the work instructions. Safety management principles help to define the path forward for the WVDP Occupational Safety and Health Program. Roles, responsibilities, and authority of personnel stem from these ideals. WVNS and its subcontractors are guided by the following fundamental safety management principles: ''Protection of the environment, workers, and the public is the highest priority. The safety and well-being of our employees, the public, and the environment must never be compromised in the aggressive pursuit of results and accomplishment of work product. A graded approach to environment, safety, and health in design, construction, operation, maintenance, and deactivation is incorporated to ensure the protection of the workers, the public, and the environment

Full Text Available This article presents the results of a participatory action research with occupational therapists in a community of practice which purpose was to discuss the care production provided by occupational therapy to hospitalized children and adolescents. The participants were nine occupational therapists from hospitals of the city of São Paulo. Ten face-to-face meetings were conducted and a Web-mediated environment was created for conducting virtual activities. The face meetings were recorded and tapped. This article aims to present the evaluation made by the participants and researchers about the process experienced in the community. Through content analysis, seventeen reporting units were identified and grouped into four main themes: the dialogic process; theoretical and practical implications; reflective process; participatory process and its barriers. The process evaluation showed that dialogue during the meetings contributed to a sense of belonging, integration, and awareness/group cohesion and made possible discussing and reflecting on topics relevant to the practice of occupational therapist. Direct communication proved to be the main form of exchange among the professionals in the group. The participants working conditions, the computers and virtual environments access issues, the surplus work generated by meetings and the displacement in urban centers were complicating factors for the participant’s greater adhesion. Evaluation showed that this strategy favored the construction of shared knowledge, and its implementation can foster reflection, research development and knowledge production, as well as contribute to the occupational therapist professional practice improvement.

Unbelted occupants may increase the risk of injury for other occupants in a motor vehicle collision (MVC). This study evaluated the association between occupant restraint use and the risk of injury (including death) to other vehicle occupants. A population based cohort study. United States. MVC occupants (n = 152 191 unweighted, n = 18 426 684 weighted) seated between a belted or unbelted occupant and the line of the principal direction of force in frontal, lateral, and rear MVCs were sampled from the 1991-2002 National Automotive Sampling System General Estimates System. Offset MVCs were not included in the study. Risk ratios and 95% confidence intervals for injury (including death) for occupants seated contiguous to unbelted occupants compared to occupants seated contiguous to belted occupants. Risk ratios were adjusted for at risk occupant's sex, age, seating position, vehicle type, collision type, travel speed, crash severity, and at risk occupants' own seat belt use. Exposure to unbelted occupants was associated with a 40% increased risk of any injury. Belted at risk occupants were at a 90% increased risk of injury but unbelted occupants were not at increased risk. Risks were similar for non-incapacitating and capacitating injuries. There was a 4.8-fold increased risk of death for exposed belted occupants but no increased risk of death for unbelted occupants. Belted occupants are at an increased risk of injury and death in the event of a MVC from unbelted occupants.

Consideration is made of the latest reports, reflecting the statistically significant increase of the lung cancer among workers in underground working sites at cumulative exposure to radon decay products under 60 monthly working levels. The significance of the non-radiation components of the occupational environment, participating in the carcinogenic process together with the classical noxiousness are emphasized. The significance of the functional sufficiency of the immune and endocrine systems, the tobacco smoking and the role of the inflammation respiratory tract diseases , etc. is denoted. Inferences are made for the complexity and multiformity of the occupational carcinogenesis according to the intensity, classical mutagenic factors and multitude of noncarcinogenic components of the occupational environment. Paralelly to the sanitary-technical fool-proof rendering of the respective productions, the necessity of purposeful balneotherapeutic and medical treatment of the risk worker contingents is pointed out

2011-12-01

The main purpose of this study was to explore factors influencing job satisfaction and dissatisfaction among Jordanian occupational therapists. Ours was an explorative qualitative study involving the use of structured open-ended written questions. Participants were asked to answer in narrative their perception about the factors behind their job satisfaction and dissatisfaction. In addition, they were asked to express their suggestions, ideas, or solutions for increasing job satisfaction. Ninety-three occupational therapists responded to the survey. For job satisfaction questions, four themes emerged: a humanistic profession; professional issues; work benefits; and work environment. Participant's comments at the end of the survey revealed one general theme for improving job satisfaction, 'a call for improvement'. This qualitative study revealed that the humanistic nature of occupational therapist was counterbalanced by several dissatisfying factors for occupational therapy practitioners in Jordan. The need for better supported working conditions in terms of financial rewards, recognition, awareness and resources as well as public and professional recognition of occupational therapists are needed to enhance the occupational therapy profile in Jordan. A comprehensive collaboration is highly needed between the individual practitioners, representatives of the profession, government and hospital administrators. © 2011 The Authors.

[Management, quality of health and occupational safety and hospital organization: is integration possible?].

Science.gov (United States)

Corrao, Carmela Romana Natalina

2011-01-01

The evolution of the national and European legislation has progressively transformed the working environments into organized environments. Specific models for its management are being proposed, which should be integrated into general management strategies. In the case of hospitals this integration should consider the peculiar organizational complexity, where the management of the occupational risk needs to be integrated with clinical risk management and economic risk management. Resources management should also consider that Occupational Medicine has not a direct monetary benefit for the organisation, but only indirect health consequences in terms of reduction of accidents and occupational diseases. The deep and simultaneous analysis of the current general management systems and the current management methods of occupational safety and health protection allows one to hyphotesise a possible integration between them. For both of them the Top Management is the main responsible of the quality management strategies and the use of specific documents in the managerial process, such as the document of risks evaluation in the occupational management and the quality manual in the general management, is of paramount importance. An integrated management has also the scope to pursue a particular kind of quality management, where ethics and job satisfaction are innovative, as established by recent European guidelines, management systems and national legislations.

Seeing (and Doing) Conservation Through Cultural Lenses

Peterson, Richard B.; Russell, Diane; West, Paige; Brosius, J. Peter

2010-01-01

In this paper, we first discuss various vantage points gained through the authors’ experience of approaching conservation through a “cultural lens.” We then draw out more general concerns that many anthropologists hold with respect to conservation, summarizing and commenting on the work of the Conservation and Community Working Group within the Anthropology and Environment Section of the American Anthropological Association. Here we focus on both critiques and contributions the discipline of anthropology makes with regard to conservation, and show how anthropologists are moving beyond conservation critiques to engage actively with conservation practice and policy. We conclude with reflections on the possibilities for enhancing transdisciplinary dialogue and practice through reflexive questioning, the adoption of disciplinary humility, and the realization that “cross-border” collaboration among conservation scholars and practitioners can strengthen the political will necessary to stem the growing commoditization and ensuing degradation of the earth’s ecosystems.

Creating a Future for Occupational Health.

Economic, social, technical, and political drivers are fundamentally changing the nature of work and work environments, with profound implications for the field of occupational health. Nevertheless, researchers and practitioners entering the field are largely being trained to assess and control exposures using approaches developed under old models of work and risks. A speaker series and symposium were organized to broadly explore current challenges and future directions for the occupational health field. Broad themes identified throughout these discussions are characterized and discussed to highlight important future directions of occupational health. Despite the relatively diverse group of presenters and topics addressed, some important cross-cutting themes emerged. Changes in work organization and the resulting insecurity and precarious employment arrangements change the nature of risk to a large fraction of the workforce. Workforce demographics are changing, and economic disparities among working groups are growing. Globalization exacerbates the 'race to the bottom' for cheap labor, poor regulatory oversight, and limited labor rights. Largely, as a result of these phenomena, the historical distinction between work and non-work exposures has become largely artificial and less useful in understanding risks and developing effective public health intervention models. Additional changes related to climate change, governmental and regulatory limitations, and inadequate surveillance systems challenge and frustrate occupational health progress, while new biomedical and information technologies expand the opportunities for understanding and intervening to improve worker health. The ideas and evidences discussed during this project suggest that occupational health training, professional practice, and research evolve towards a more holistic, public health-oriented model of worker health. This will require engagement with a wide network of stakeholders. Research and

Extending Beyond Qualitative Interviewing to Illuminate the Tacit Nature of Everyday Occupation: Occupational Mapping and Participatory Occupation Methods.

2015-07-01

The study of human occupation requires a variety of methods to fully elucidate its complex, multifaceted nature. Although qualitative approaches have commonly been used within occupational therapy and occupational science, we contend that such qualitative research must extend beyond the sole use of interviews. Drawing on qualitative methodological literature, we discuss the limits of interview methods and outline other methods, particularly visual methods, as productive means to enhance qualitative research. We then provide an overview of our critical ethnographic study that used narrative, visual, and observational methods to explore the occupational transitions experienced by immigrants to Canada. We describe our use of occupational mapping and participatory occupation methods and the contributions of these combined methods. We conclude that adopting a variety of methods can enable a deeper understanding of the tacit nature of everyday occupation, and is key to advancing knowledge regarding occupation and to informing occupational therapy practice.

Effects of post-fire logging on California spotted owl occupancy

Directory of Open Access Journals (Sweden)

Chad T. Hanson

2018-01-01

Full Text Available In fire-adapted forest ecosystems around the world, there has been growing concern about adverse impacts of post-fire logging on native biodiversity and ecological processes. This is also true in conifer forests of California, U.S.A. which are home to a rare and declining owl subspecies, the California spotted owl (Strix occidentalis occidentalis. While there has been recent concern about the California spotted owl occupancy in large fire areas where some territories have substantial high-severity fire effects, the influence of post-fire logging on the California spotted owl occupancy has been investigated very little, leading to some uncertainty about interpretation of conflicting results in different large fires. Research has found these owls preferentially select high-severity fire areas, characterised by high levels of snags and native shrubs, for foraging in forests that were not logged after fire, suggesting that removal of this foraging habitat might impact occupancy. The authors assessed the effect of post-fire logging and high-severity fire, on occupancy of this subspecies in eight large fire areas, within spotted owl sites with two different levels of high-severity fire effects. They found a significant adverse effect of such logging and no effect of high-severity fire alone. These results indicate it is post-fire logging, not large fires themselves, that poses a conservation threat to this imperilled species.

Full Text Available In this paper, we propose a new HVAC (heating, ventilation, and air conditioning control strategy as part of the smart energy system that can balance occupant comfort against building energy consumption using ubiquitous sensing and machine learning technology. We have developed ZigBee-based wireless sensor nodes and collected realistic temperature and humidity data during one month from a laboratory environment. With the collected data, we have established a building environment model using machine learning algorithms, which can be used to assess occupant comfort level. We expect the proposed HVAC control strategy will be able to provide occupants with a consistently comfortable working or home environment.

Inference for occupancy and occupancy dynamics

O'Connell, Allan F.; Bailey, Larissa L.; O'Connell, Allan F.; Nichols, James D.; Karanth, K. Ullas

2011-01-01

This chapter deals with the estimation of occupancy as a state variable to assess the status of, and track changes in, species distributions when sampling with camera traps. Much of the recent interest in occupancy estimation and modeling originated from the models developed by MacKenzie et al. (2002, 2003), although similar methods were developed independently (Azuma et al. 1990; Bayley and Petersen 2001; Nichols and Karanth, 2002; Tyre et al. 2003), all of which deal with species occurrence information and imperfect detection. Less than a decade after these publications, the modeling and estimation of species occurrence and occupancy dynamics have increased significantly. Special features of scientific journals have explored innovative uses of detection–nondetection data with occupancy models (Vojta 2005), and an entire volume has synthesized the use and application of occupancy estimation methods (MacKenzie et al. 2006). Reviews of the topical concepts, philosophical considerations, and various sampling designs that can be used for occupancy estimation are now readily available for a range of audiences (MacKenzie and Royle 2005; MacKenzie et al. 2006; Bailey et al. 2007; Royle and Dorazio 2008; Conroy and Carroll 2009; Kendall and White 2009; Hines et al. 2010; Link and Barker 2010). As a result, it would be pointless here to recast all that these publications have so eloquently articulated, but that said, a review of any scientific topic requires sufficient context and relevant background information, especially when relatively new methodologies and techniques such as occupancy estimation and camera traps are involved. This is especially critical in a digital age where new information is published at warp speed, making it increasingly difficult to stay abreast of theoretical advances and research developments.

There are few studies in occupational therapy that compare the perceptions of supervisors and students regarding quality clinical placement programmes, and those that exist indicate substantial differences in the perceptions held by each group. This pilot study was conducted using a cross-sectional descriptive design, with a single questionnaire distributed to occupational therapy students and clinical supervisors. A total of 40 questionnaires were returned: 17 from students and 23 from clinical supervisors. Differences were found between the perceptions of occupational therapy students and clinical supervisors in response to four topics: preparation from the university for their placements; consistency across placement sites; instances of supervisors seeking feedback from students; and the burden associated with the placement-related workload for clinicians. Differences were found between the perceptions of occupational therapy students and clinical supervisors in response to four topics DISCUSSION: Different perceptions around preparation from universities and consistency across placement sites relate to the existing roles of each group: students are more aware of university preparation and clinical supervisors are more aware of organisational inconsistencies in their respective usual work environments. The discrepancy in the perceived seeking of feedback from students has also been reported in student debriefing sessions. The burdens perceived by clinical supervisors appear to be influenced by a belief that clinical education is an additional duty rather than a core role. © 2016 John Wiley & Sons Ltd.

Occupational health nursing focuses on promotion and restoration of health, prevention of illness and injury, protection from work-related and environmental hazards, and corporate profitability. Quality education about the relationship between work and health is critical for nurses' success regardless of work setting, and is consistent with Healthy People 2020 goals, but is lacking or limited in some programs. This report introduces an innovative occupational health nursing curriculum for students enrolled in baccalaureate nursing programs. The process of designing and pilot testing this novel curriculum, its alignment with nursing competencies, and its format and learning activities are described. Preparing professional nurses to understand the role of the occupational health nurse and the relationship between work and health is an essential curricular consideration for contemporary nursing education. © 2015 The Author(s).

This study estimates job-related risks among common low wage occupations (cleaning, construction, food service, cashier/baggers, and factory workers) held by predominantly Haitian, El Salvadorian, and Brazilian immigrants living or working in Somerville, Massachusetts. A community-based cross-sectional survey on immigrant occupational health was conducted between 2006 and 2009 and logistic regression was used to assess the job-related risks among the most common low wage occupations. Construction workers reported significantly higher health risks, and lower access to occupational health services than the other occupations. Compared to cashier/baggers, the reference population in this study, cleaners reported significantly lower access to health and safety and work training and no knowledge of workers' compensation. Factory workers reported significantly lower work training compared to cashier/baggers. Food service workers reported the least access to doctors compared to the other occupations. We found significant variability in risks among different low wage immigrant occupations. The type of occupation independently contributed to varying levels of risks among these jobs. We believe our findings to be conservative and recommend additional inquiry aimed at assuring the representativeness of our findings. © 2013 Wiley Periodicals, Inc.

Rules and recent trends for setting health-based occupational exposure limits for chemicals.

Skowroń, Jolanta; Czerczak, Sławomir

2015-01-01

The working environment is the special case of the non-natural environment created by man in which the increased production activity brings about the concentration of stimulators particularly aggressive to the human organism, such as chemical hazards, noise, vibration, extreme temperatures, and finally, intensified psychological and emotional stress. Depending on the nature and intensity, working environment factors have been classified into dangerous, harmful and annoying. The workers are more and more frequently exposed to dangerous chemicals in the working environment. The chemicals cause many diseases including, in the 1st place, respiratory insufficiency, inflammatory skin conditions, psychoneurological disorders and neoplastic diseases. Occupational exposure limit values (OELs), the main criteria for occupational exposure assessment, constitute an important factor for the safe use of chemicals in the working environment. In Poland, to date there are 524 chemical substances and 19 dusts for which maximum admissible concentrations (MAC) have been established.

Sampling scales define occupancy and underlying occupancy-abundance relationships in animals.

Steenweg, Robin; Hebblewhite, Mark; Whittington, Jesse; Lukacs, Paul; McKelvey, Kevin

2018-01-01

Occupancy-abundance (OA) relationships are a foundational ecological phenomenon and field of study, and occupancy models are increasingly used to track population trends and understand ecological interactions. However, these two fields of ecological inquiry remain largely isolated, despite growing appreciation of the importance of integration. For example, using occupancy models to infer trends in abundance is predicated on positive OA relationships. Many occupancy studies collect data that violate geographical closure assumptions due to the choice of sampling scales and application to mobile organisms, which may change how occupancy and abundance are related. Little research, however, has explored how different occupancy sampling designs affect OA relationships. We develop a conceptual framework for understanding how sampling scales affect the definition of occupancy for mobile organisms, which drives OA relationships. We explore how spatial and temporal sampling scales, and the choice of sampling unit (areal vs. point sampling), affect OA relationships. We develop predictions using simulations, and test them using empirical occupancy data from remote cameras on 11 medium-large mammals. Surprisingly, our simulations demonstrate that when using point sampling, OA relationships are unaffected by spatial sampling grain (i.e., cell size). In contrast, when using areal sampling (e.g., species atlas data), OA relationships are affected by spatial grain. Furthermore, OA relationships are also affected by temporal sampling scales, where the curvature of the OA relationship increases with temporal sampling duration. Our empirical results support these predictions, showing that at any given abundance, the spatial grain of point sampling does not affect occupancy estimates, but longer surveys do increase occupancy estimates. For rare species (low occupancy), estimates of occupancy will quickly increase with longer surveys, even while abundance remains constant. Our results

This qualitative study investigated how resilience functions in the context of daily occupations for mothers of children with autism spectrum disorder (ASD). Fourteen mothers of children with ASD participated in two focus groups that were used to elicit stories of the mothers' resilience in daily occupations. A constant comparative method was used for data analysis. A model of resilience in daily occupations of mothers of children with ASD was developed consisting of four categories: (1) creating and re-creating accepting conditions, (2) finding solutions, (3) striving for balance among daily occupations, and (4) thinking about the child's future. Sources of resilience were found to reside in both the mothers themselves and their social environments. Occupational therapy practitioners can use these findings in developing supportive approaches aimed at mothers, family members, and other people in the lives of children with ASD.

Stramler, J.

1992-01-01

Ergonomics is often defined simply as the study of work. Related or synonymous terms include human factors, human engineering, engineering psychology, and others. Occupational ergonomics is a term that has been proposed to describe the study of the working environment, including the physical consequences resulting from having an improperly designed workplace. The routine space working environment presents some problems not found in the typical Earthbound workplace. These include radiation, intravehicular contamination/pollution, temperature extremes, impact with other objects, limited psychosocial relationships, sensory deprivation, and reduced gravity. These are important workplace considerations, and may affect astronauts either directly at work or at some point during their life as a result of their work under these conditions. Some of the major issues associated with each of these hazards are presented.

The primary responsibility of the Health, Safety, and Environment (HSE) Division at the Los Alamos National Laboratory is to provide comprehensive occupational health and safety programs, waste processing, and environmental protection. These activities are designed to protect the worker, the public, and the environment. Many disciplines are required to meet the responsibilities, including radiation protection, industrial hygiene, safety, occupational medicine, environmental science, epidemiology, and waste management. New and challenging health and safety problems occasionally arise from the diverse research and development work of the Laboratory. Research programs in HSE Division often stem from these applied needs. These programs continue but are also extended, as needed, to study specific problems for the Department of Energy and to help develop better occupational health and safety practices. 52 refs

Conclusion: This study revealed a poor level of the implementation of occupational health services in Iranian self-employed enterprises. Based on the findings, providing basic training on the occupational health, more enforcing in conduction of health examinations and providing PPE, and taking appropriate strategies aimed at eliminating or minimizing work environment harmful agents are the major factor that should be considered to improve the level of occupational health services among the studied enterprises.

Influence of connectivity, wild prey and disturbance on occupancy of tigers in the human-dominated western Terai Arc Landscape.

Full Text Available Occupying only 7% of their historical range and confined to forested habitats interspersed in a matrix of human dominated landscapes, tigers (Panthera tigris typify the problems faced by most large carnivores worldwide. With heads of governments of tiger range countries pledging to reverse the extinction process and setting a goal of doubling wild tiger numbers by 2022, achieving this target would require identifying existing breeding cores, potential breeding habitats and opportunities for dispersal. The Terai Arc Landscape (TAL represents one region which has recently witnessed recovery of tiger populations following conservation efforts. In this study, we develop a spatially explicit tiger occupancy model with survey data from 2009-10 based on a priori knowledge of tiger biology and specific issues plaguing the western TAL (6,979 km(2, which occurs in two disjunct units (Tiger Habitat Blocks; THBs. Although the overall occupancy of tigers was 0.588 (SE 0.071, our results clearly indicate that loss in functionality of a regional corridor has resulted in tigers now occupying 17.58% of the available habitat in THB I in comparison to 88.5% in THB II. The current patterns of occupancy were best explained by models incorporating the interactive effect of habitat blocks (AIC w = 0.883 on wild prey availability (AIC w = 0.742 and anthropogenic disturbances (AIC w = 0.143. Our analysis has helped identify areas of high tiger occupancy both within and outside existing protected areas, which highlights the need for a unified control of the landscape under a single conservation unit with the primary focus of managing tigers and associated wildlife. Finally, in the light of global conservation targets and recent legislations in India, our study assumes significance as we identify opportunities to secure (e.g. THB II and increase (e.g. THB I tiger populations in the landscape.

Objective To identify the factors associated with fatal occupational injuries in Mexico in 2012 among workers affiliated with the Mexican Social Security Institute. Methods Analysis of secondary data using information from the National Occupational Risk Information System, with the consequence of the occupational injury (fatal versus non-fatal) as the response variable. The analysis included 406,222 non-fatal and 1,140 fatal injuries from 2012. The factors associated with the lethality of the injury were identified using a logistic regression model with the Firth approach. Results Being male (OR=5.86; CI95%: 4.22-8.14), age (OR=1.04; CI95%: 1.03-1.06), employed in the position for 1 to 10 years (versus less than 1 year) (OR=1.37; CI95%: 1.15-1.63), working as a facilities or machine operator or assembler (OR: 3.28; CI95%: 2.12- 5.07) and being a worker without qualifications (OR=1.96; CI95%: 1.18-3.24) (versus an office worker) were associated with fatality in the event of an injury. Additionally, companies classified as maximum risk (OR=1.90; CI 95%: 1.38-2.62), workplace conditions (OR=7.15; CI95%: 3.63-14.10) and factors related to the work environment (OR=9.18; CI95%:4.36-19.33) were identified as risk factors for fatality in the event of an occupational injury. Conclusions Fatality in the event of an occupational injury is associated with factors related to sociodemographics (age, sex and occupation), the work environment and workplace conditions. Worker protection policies should be created for groups with a higher risk of fatal occupational injuries in Mexico. PMID:25790063

2017-02-01

There is a need for a conceptual practice model that explicates ecological complexities involved in using occupation to optimize the quality of life of institutionalized people with dementia. This study aimed to prepare the Lived Environment Life Quality Model, a dementia-specific conceptual practice model of occupational therapy in institutional facilities, for publication and application to practice. Interviews and focus groups with six expert occupational therapists were subjected to qualitative content analysis to confirm, disconfirm, and further develop the model. The model's lived-environment domain as the focus of assessment and intervention was extensively confirmed, and its quality-of-life domain as the focus of intervention goals and outcomes was both confirmed and further developed. As confirmed in this study, the Lived Environment Life Quality Model is a client-centred, ecologically valid, and occupation-focused guide to optimizing quality of life of institutionalized adults with dementia in present moments and progressively over time.

To assess the occupational stress and its influential factors in nurses. A test of occupational stress, its influential factors, work ability were carried out for 248 nurses and 319 controls with revised occupational stress inventory (OSI-R) and work ability index (WAI). The scores of personal cope resource (131.266 +/- 17.176) and work ability index (32.581 +/- 3.158) in nurse group were significantly higher than those in control group (126.931 +/- 19.108, 31.840 +/- 4.069) (P < 0.05). The main occupational stressors scores (role insufficiency, role clash, and responsibility) in nurses were higher than those in controls (P < 0.05). The stress response of interpersonal relationship in nurses was also higher. The items of personal cope resource, such as recreation, self-care and social support of nurses were superior to those of controls (P < 0.05). Stress response was positively correlated with occupational role (r = 0.512, P < 0.01), and negatively correlated with the personal cope resource (r = -0.475, P < 0.01). The primary influential factors of personal stress were recreation, social support, rational conduct, role insufficiency, role clash, responsibility, and poor work environment. To strengthen social support, to improve work condition for nurses, so as to reduce the occupational stress and to enhance the work ability of nurses are important task in occupational health field.

The effectiveness of conservation interventions to overcome the urban-environmental paradox.

McDonald, Robert I

2015-10-01

Globally, urbanization is rapidly growing cities and towns at a historically unprecedented rate, and this rapid urban growth is influencing many facets of the environment. This paper reviews the effectiveness of conservation interventions that are designed to increase urban sustainability. It presents evidence for an apparent urban-environmental paradox: while the process of urban growth converts natural habitat to other land covers and degrades natural resources and ecosystem function, the increase in human population can increase demand for natural resources and ecosystem services. The fundamental problem that many conservation interventions try to address is that most facets of the environment are common or public goods, and are hence undervalued in decision making (market failure). The paper presents a threefold classification of conservation interventions in cities: conservation in the city (protecting biodiversity), conservation by the city (reducing per capita resource and energy use), and conservation for cities (projects that maintain or enhance ecosystem services). It ends by discussing methods for spatially targeting conservation interventions of all three types and for quantifying the effectiveness of interventions retrospectively. © 2015 New York Academy of Sciences.

Can occupancy-abundance models be used to monitor wolf abundance?

Directory of Open Access Journals (Sweden)

M Cecilia Latham

Full Text Available Estimating the abundance of wild carnivores is of foremost importance for conservation and management. However, given their elusive habits, direct observations of these animals are difficult to obtain, so abundance is more commonly estimated from sign surveys or radio-marked individuals. These methods can be costly and difficult, particularly in large areas with heavy forest cover. As an alternative, recent research has suggested that wolf abundance can be estimated from occupancy-abundance curves derived from "virtual" surveys of simulated wolf track networks. Although potentially more cost-effective, the utility of this approach hinges on its robustness to violations of its assumptions. We assessed the sensitivity of the occupancy-abundance approach to four assumptions: variation in wolf movement rates, changes in pack cohesion, presence of lone wolves, and size of survey units. Our simulations showed that occupancy rates and wolf pack abundances were biased high if track surveys were conducted when wolves made long compared to short movements, wolf packs were moving as multiple hunting units as opposed to a cohesive pack, and lone wolves were moving throughout the surveyed landscape. We also found that larger survey units (400 and 576 km2 were more robust to changes in these factors than smaller survey units (36 and 144 km2. However, occupancy rates derived from large survey units rapidly reached an asymptote at 100% occupancy, suggesting that these large units are inappropriate for areas with moderate to high wolf densities (>15 wolves/1,000 km2. Virtually-derived occupancy-abundance relationships can be a useful method for monitoring wolves and other elusive wildlife if applied within certain constraints, in particular biological knowledge of the surveyed species needs to be incorporated into the design of the occupancy surveys. Further, we suggest that the applicability of this method could be extended by directly incorporating some of its

Occupational allergy as a challenge to developing countries.

A steady increase in the incidence of allergic diseases can be observed since 1950s. For such atopic diseases as bronchial asthma, pollinosis or atopic dermatitis, a significantly increased morbidity rate in the general population has been found. Strikingly enough, the highest prevalence of asthma and allergy was recorded in highly developed countries. It can thus be assumed that the high rate of asthma may be an attribute of the post-industrial societies. The prevalence of occupational allergies is thought to be in direct proportion to the rate with which allergies occur in the general population. In view of the changing environment and lifestyles in the developing countries, their communities are expected to be faced with similar negative epidemiological effects concerning allergies. To counteract the spreading of negative health effects, the following measures need to be undertaken: 1. Limitation of exposure to strong allergens. 2. Modification of the training curriculum for medical personnel and of health service infrastructure, according to new tasks and challenges. 3. Considering a possibility of introducing a system of surveillance over occupational allergies and asthma, like the Surveillance of Work-related and Occupational Respiratory Disease (SWORD) system implemented in UK. This system ensures effective cooperation between specialists in preventive medicine, occupational hygiene services and research workers dealing with occupational health that enables prompt response to emerging hazards.

This study aimed to develop a methodological tool to analyze and monitor the green jobs in the context of Occupational Health and Safety. A literature review in combination with an investigation of Occupational Health Indicators was performed. The resulting tool of Occupational Health Indicators was based on the existing information of "Single Report" and was validated by national's experts. The tool brings together 40 Occupational Health Indicators in four key fields established by World Health Organization in their conceptual framework "Health indicators of sustainable jobs." The tool proposed allows for assessing if the green jobs enabled to follow the principles and requirements of Occupational Health Indicators and if these jobs are as good for the environment as for the workers' health, so if they can be considered quality jobs. This shows that Occupational Health Indicators are indispensable for the assessment of the sustainability of green jobs and should be taken into account in the definition and evaluation of policies and strategies of the sustainable development.

Modifying the home environments of older people as they age in place is a well-established health and social care intervention. Using design and construction methods to redress any imbalance caused by the ageing process or disability within the home environment, occupational therapists are seen as the experts in this field of practice. However, the process used by occupational therapists when modifying home environments has been criticised for being disorganised and not founded on theoretical principles and concepts underpinning the profession. To address this issue, research was conducted to develop a design and construction process protocol specifically for home modifications. A three-stage approach was taken for the analysis of qualitative data generated from an online survey, completed by 135 occupational therapists in the UK. Using both the existing occupational therapy intervention process model and the design and construction process protocol as the theoretical frameworks, a 4-phase, 9-subphase design and construction process protocol for home modifications was developed. Overall, the study is innovative in developing the first process protocol for home modifications, potentially providing occupational therapists with a systematic and effective approach to the design and delivery of home modification services for older and disabled people.

Experience of Client-centered Practice amongst Danish Occupational Therapists

Larsen, Anette Enemark

A client-centered approach is on the health care agenda in many European countries (1), and amongst these Denmark (2). It is described as the foundation for Occupational Therapy (OT) (3), a code of professional conduct (4,5), and defined as a partnership between client and therapist (3). The goal...... is to empower a client to fulfil his/her occupational roles in a variety of environments, leading to an increase in intervention efficacy and client perception of intervention quality (3). However, it is known to be challenging (1,3). Given the importance of this approach, there has been limited exploration...

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

The management system of occupational diseases in Korea can be assessed from the perspective of a surveillance system. Workers' compensation insurance reports are used to produce official statistics on occupational diseases in Korea. National working conditions surveys are used to monitor the magnitude of work-related symptoms and signs in the labor force. A health examination program was introduced to detect occupational diseases through both selective and mass screening programs. The Working Environment Measurement Institution assesses workers' exposure to hazards in the workplace. Government regulates that the employer should do health examinations and working conditions measurement through contracted private agencies and following the Occupational Safety and Health Act. It is hoped that these institutions may be able to effectively detect and monitor occupational diseases and hazards in the workplace. In view of this, the occupational management system in Korea is well designed, except for the national survey system. In the future, national surveys for detection of hazards and ill-health outcomes in workers should be developed. The existing surveillance system for occupational disease can be improved by providing more refined information through statistical analysis of surveillance data.

2000-06-01

1. Information technology has moved "work" out of a centralized location. Employees who telecommute pose significant challenges and considerations for the practice of occupational health nursing. 2. Employer and employee benefits associated with telecommuting are reportedly associated with high levels of job satisfaction. However, the occupational health and safety risks of this new work environment need to be fully assessed and understood. 3. The ergonomic controls to minimize the risk of repetitive motion injuries are the same for both office and home locations. Additional attention need to be paid to implementing risk controls for other physical hazards and psychosocial considerations, as well as personal safety and security issues. 4. The scope of occupational health nursing practice needs to remain dynamic, recognizing the impact new technologies have on the workplace, to continue to meet the needs of the changing workplace.

The sustainable urban development growth in the ASEAN region has accelerated tremendously. More demand on the sustainable development has led to bigger market driven certified green neighborhood and buildings. However, there is a lack of post-occupancy evaluation study conducted in assessing the end-users perspective on the certified sustainable neighborhood development. This paper aims to investigate the end-users point of view on sustainable dimension pillar (SDP) adaptation based on environment dimension, social dimension and economic dimension using Post-Occupancy Evaluation Model (POEM) framework. The research methodology employed stakeholders-Inclusion Approach survey questionnaires in order to obtained the sustainable dimensional adaptation score. The results show that there is sustainable dimension gap in POEM evaluation, hence, suggested the pre- occupancy criteria did not fulfill the SDP adaptation and pre-occupancy criteria and variables if differ from post-occupancy criteria and variables.

Determining how species coexist is critical for understanding functional diversity, niche partitioning and interspecific interactions. Identifying the direct and indirect interactions among sympatric carnivores that enable their coexistence is particularly important to elucidate because they are integral for maintaining ecosystem function. We studied the effects of removing nine fishers (Pekania pennanti) on their population dynamics and used this perturbation to elucidate the interspecific interactions among fishers, grey foxes (Urocyon cinereoargenteus) and ringtails (Bassariscus astutus). Grey foxes (family: Canidae) are likely to compete with fishers due to their similar body sizes and dietary overlap, and ringtails (family: Procyonidae), like fishers, are semi-arboreal species of conservation concern. We used spatial capture-recapture to investigate fisher population numbers and dynamic occupancy models that incorporated interspecific interactions to investigate the effects members of these species had on the colonization and persistence of each other's site occupancy. The fisher population showed no change in density for up to 3 years following the removals of fishers for translocations. In contrast, fisher site occupancy decreased in the years immediately following the translocations. During this same time period, site occupancy by grey foxes increased and remained elevated through the end of the study. We found a complicated hierarchy among fishers, foxes and ringtails. Fishers affected grey fox site persistence negatively but had a positive effect on their colonization. Foxes had a positive effect on ringtail site colonization. Thus, fishers were the dominant small carnivore where present and negatively affected foxes directly and ringtails indirectly. Coexistence among the small carnivores we studied appears to reflect dynamic spatial partitioning. Conservation and management efforts should investigate how intraguild interactions may influence the

Opportunities and obstacles in translating evidence to policy in occupational asthma.

Occupational asthma (OA), a common respiratory disorder in Western countries, is caused by exposures at the workplace. It is part of a broader definition of work-related asthma (WRA) that also includes pre-existing asthma aggravated by substances present in the workplace environment, and it is potentially preventable. The purpose of this paper is to illustrate preventive measures for occupational asthma by case studies. In three case studies we discuss preventive measures that have been associated with reductions in incidence of occupational asthma from natural rubber latex and from diisocyanates as supported by published literature. We also discuss challenges in relation to asthma from cleaning products in healthcare work. Several preventive measures have been associated with reduction in incidence of occupational asthma from natural rubber latex and from diisocyanates, and may provide lessons for prevention of other causes of occupational asthma. Cleaning products remain an unresolved problem at present with respect to asthma risks but potential measures include the use of safer products and safer applications such as avoidance of spray products, use of occupational hygiene methods such as improving local ventilation, and when appropriate, the use of personal protective devices.

PREVENTION OF OCCUPATIONAL ACCIDENTS

Directory of Open Access Journals (Sweden)

Jovica Jovanovic

2004-01-01

Full Text Available Medical services, physicians and nurses play an essential role in the plant safety program through primary treatment of injured workers and by helping to identify workplace hazards. The physician and nurse should participate in the worksite investigations to identify specific hazard or stresses potentially causing the occupational accidents and injuries and in planning the subsequent hazard control program. Physicians and nurses must work closely and cooperatively with supervisors to ensure the prompt reporting and treatment of all work related health and safety problems. Occupational accidents, work related injuries and fatalities result from multiple causes, affect different segments of the working population, and occur in a myriad of occupations and industrial settings. Multiple factors and risks contribute to traumatic injuries, such as hazardous exposures, workplace and process design, work organization and environment, economics, and other social factors. With such a diversity of theories, it will not be difficult to understand that there does not exist one single theory that is considered right or correct and is universally accepted. These theories are nonetheless necessary, but not sufficient, for developing a frame of reference for understanding accident occurrences. Prevention strategies are also varied, and multiple strategies may be applicable to many settings, including engineering controls, protective equipment and technologies, management commitment to and investment in safety, regulatory controls, and education and training. Research needs are thus broad, and the development and application of interventions involve many disciplines and organizations.

Occupational noise and ischemic heart disease: A systematic review

2016-01-01

Full Text Available Noise exposure might be a risk factor for ischemic heart disease (IHD. Unlike residential exposure, however, evidence for occupational noise is limited. Given that high-quality quantitative synthesis of existing data is highly warranted for occupational safety and policy, we aimed at conducting a systematic review and meta-analysis of the risks of IHD morbidity and mortality because of occupational noise exposure. We carried out a systematic search in MEDLINE, EMBASE, and on the Internet since April 2, 2015, in English, Spanish, Russian, and Bulgarian. A quality-scoring checklist was developed a priori to assess different sources of methodological bias. A qualitative data synthesis was performed. Conservative assumptions were applied when appropriate. A meta-analysis was not feasible because of unresolvable methodological discrepancies between the studies. On the basis of five studies, there was some evidence to suggest higher risk of IHD among workers exposed to objectively assessed noise >75–80 dB for <20 years (supported by one high, one moderate, and one low quality study, opposed by one high and one moderate quality study. Three moderate and two low quality studies out of six found self-rated exposure to be associated with higher risk of IHD, and only one moderate quality study found no effect. Out of four studies, a higher mortality risk was suggested by one moderate quality study relying on self-rated exposure and one of high-quality study using objective exposure. Sensitivity analyses showed that at higher exposures and in some vulnerable subgroups, such as women, the adverse effects were considerably stronger. Despite methodological discrepancies and limitations of the included studies, occupational noise appeared to be a risk factor for IHD morbidity. Results suggested higher risk for IHD mortality only among vulnerable subgroups. Workers exposed to high occupational noise should be considered at higher overall risk of IHD.

Developments in information and communication systems, organisational structure and the nature of work have contributed to the restructuring of work environments. In these new types of work environments, employees do not have assigned workplaces. This arrangement helps organisations to minimise rent costs and increase employee interaction and knowledge exchange through mobility. This post-occupancy evaluation (POE) study focuses on a flexible office in a Gold Leadership in Energy and Environmental Design-certified building in Istanbul. An integrated qualitative and quantitative POE technique with occupancy tracking via barcode scanning and instant surveying has been introduced. Using this unique approach, we examined the directives/drivers in workplace choice and mobility from different perspectives. The aggregated data was used to discern work-related consequences such as flexibility, workplace choice, work and indoor environment satisfaction, place attachment and identity. The results show that employees who have a conventional working culture develop a new working style: 'fixed-flexible working'. Practitioner Summary: This paper introduces a new POE approach for flexible offices based on occupancy tracking through barcode scanning to explore workplace choice and mobility. More than half (52.1%) of the participants have tended to choose the same desk every day. However, the satisfaction level of the 'mobile' employees was higher than that of the 'fixed flexible' employees.

Data collected using “Health and Safety Executive Questionnaire (HSE” and “Maslach burnout inventory (MBI”. Data were analyzed by the Excel and SPSS 16 software. Pearson correlation coefficient was used to assess relationship between stress dimension and occupation burnout factors. Findings The average of occupational stress was 3.65±0.51 and the average of burnout was 29.67±4.38. Occupational groups had no significant correlation with occupational stress (p=0.86 but had a significant correlation with burnout (p=0.006. There were significant positive correlations between occupational stress parameters and burnout parameters. Just the peer support of occupational stress had no correlations with success, emotional exhaustion and general burnout. Conclusion Deterioration of stressful parameters in occupational environment can mitigate damaging effects of burnout syndromes.

2014-12-01

This study investigates occupational therapy for early communication in children with autism spectrum disorders (ASD). The research explored the role of occupational therapists in supporting children with ASD to become better communicators by considering their inter-professional collaboration with speech-language pathologists. Convenience samples of 21 clinical occupational therapists and speech-language pathologists were recruited to participate in semi-structured audio-recorded focus groups, using a qualitative design. Distinct views included a child-centred focus from speech-language pathologists, whereas occupational therapists spoke of the child through societal viewpoints, which later pointed to occupational therapists' proficiency in enabling skill generalization in ASD. An equal partnership was consistently reported between these clinicians, who identified the same objectives, shared strategies, joint treatments, and ongoing collaboration as the four main facilitators to inter-professional collaboration when treating children with ASD. Three unique roles of occupational therapy comprised developing non-verbal and verbal communication pre-requisites, adapting the setting, educating-partnering-advocating for the child, and providing occupation-based intervention. These three themes meshed with the discipline-specific occupational therapy domains represented in the Person-Environment-Occupation framework. When working in inter-professional collaboration, speech-language pathologists and occupational therapists agree that occupational therapy is indispensable to early intervention in enabling communication in ASD.

There is growing attention to participation and social participation in literature and policy reports. Occupational therapists strongly believe that creating coherence between the person's occupations and environment will facilitate participation of each individual. Nowadays, societal developments such as "health literacy and self-management", "Web 2.0 social media", "empowering communities", and "Nothing About Us Without Us" increase opportunities for people to interact on different levels of social participation. Social participation can be used as an outcome, though it can also be seen as a means to change society and to develop solutions for barriers experienced by people with chronic diseases or disabilities. Societal developments will have an impact on social participation in terms of supporting each other and contributing to society. Additionally, these changes will have a major influence on the way we educate, conduct research, and deliver occupational therapy practice.

Re-evaluating occupational heat stress in a changing climate.

Science.gov (United States)

Spector, June T; Sheffield, Perry E

2014-10-01

The potential consequences of occupational heat stress in a changing climate on workers, workplaces, and global economies are substantial. Occupational heat stress risk is projected to become particularly high in middle- and low-income tropical and subtropical regions, where optimal controls may not be readily available. This commentary presents occupational heat stress in the context of climate change, reviews its impacts, and reflects on implications for heat stress assessment and control. Future efforts should address limitations of existing heat stress assessment methods and generate economical, practical, and universal approaches that can incorporate data of varying levels of detail, depending on resources. Validation of these methods should be performed in a wider variety of environments, and data should be collected and analyzed centrally for both local and large-scale hazard assessments and to guide heat stress adaptation planning. Heat stress standards should take into account variability in worker acclimatization, other vulnerabilities, and workplace resources. The effectiveness of controls that are feasible and acceptable should be evaluated. Exposure scientists are needed, in collaboration with experts in other areas, to effectively prevent and control occupational heat stress in a changing climate. © The Author 2014.

Atmospheric Weathering of Historic Monuments and Their Related Conservation Issues

Full Text Available Atmospheric environment affects the materials of historic monuments and their structure starting from the time of their construction. Daily and seasonal changes in temperature and humidity, wind, snow and rainfall, soluble salts carried by water, biological agents, pollutant gases and particulate matter are some of the agents in atmospheric environment that introduce weathering by physical, chemical and biological processes in the materials of the monuments such as natural building stones, bricks, mortars and plasters, mud brick etc. The weathering processes need to be well diagnosed by identification of main mechanisms of decay and major responsible agents, degree and depth of deterioration expressed with measurable parameters of physical, physicomechanical properties, and micro structural changes together with their distribution on the monument. Success of conservation treatments strongly depend on those diagnostic studies and compatibility of the treatments with the deteriorated and relatively sound parts of the historic materials. Current approach to materials conservation is to be able to make minimum intervention to historic material by targeting the conservation treatment to the deteriorated area for the purpose of controlling the deterioration factors and achieving compatible and durable conservation of historical material. In this presentation, two examples of diagnostic research and conservation treatments based on and guided by the diagnostic results are summarized concerning historic stone monuments exposed to atmospheric environment since more than two thousand years. The first example is on the marble walls of Temple of Augustus in Ankara exposed to polluted urban atmosphere. The second example is on the limestone statues of Nemrut Mount Monument in Adıyaman-Turkey, exposed to rural atmosphere with harsh climatic conditions. Finally, a brief discussion on current research issues related to historic materials conservation in

2016-10-01

Full Text Available Agriculture is one of the most dangerous industries in the United States. Farmworkers, including migrant farmworkers, are at risk for work-related injuries. This study explores the association between stress, depression, and occupational injury among migrant farmworkers in Nebraska. Occupational injury was hypothesized to significantly increase the odds of farmworkers being stressed and depressed. Two hundred migrant farmworkers (mean age = 33.5 years, standard deviation (SD = 12.53; 93.0% men, 92.9% of Mexican descent were interviewed. In bivariate analyses, results indicated that stress and depression were positively associated with occupational injury. Two logistic regression models were developed. Occupational injury was a significant factor for depression, but not for stress. Participants who had been injured on the job were over seven times more likely to be depressed. These results highlight the interconnection between the work environment and mental health. More must be done to foster well-being in rural, agricultural communities. Improving occupational health and safety information and training, integrating behavioral health services into primary care settings, and strengthening the protections of the Migrant and Seasonal Agricultural Worker Protection Act may improve conditions for migrant farmworkers in the rural Midwest.

Conservatism implications of shock test tailoring for multiple design environments

Science.gov (United States)

Baca, Thomas J.; Bell, R. Glenn; Robbins, Susan A.

1987-01-01

A method for analyzing shock conservation in test specifications that have been tailored to qualify a structure for multiple design environments is discussed. Shock test conservation is qualified for shock response spectra, shock intensity spectra and ranked peak acceleration data in terms of an Index of Conservation (IOC) and an Overtest Factor (OTF). The multi-environment conservation analysis addresses the issue of both absolute and average conservation. The method is demonstrated in a case where four laboratory tests have been specified to qualify a component which must survive seven different field environments. Final judgment of the tailored test specification is shown to require an understanding of the predominant failure modes of the test item.

Occupational medicine practitioners should remember that certain duties are performed both at work and at home. This issue is particularly important in preventive healthcare of pregnant working women. Taking the above into consideration, we reviewed the literature with respect to nuisance and occupational risk factors, which might be associated with professional and household duties. The research indicates the need to reduce activities that require frequent bending or lifting, put a women at risk of falling or cause excess occupational stress for pregnant women. We would like to draw the doctors’ attention to the possibility of exceeding a 4-hour limit of work at video display terminals and negative effects of low physical exercise and sitting for a long time both at work and at home. Since long working hours (over 40 h/week affect the course of pregnancy negatively, total working time at work (including any additional jobs and at home must be taken into account in the occupational risk assessment.

Occupational health nursing plays a critical part in improving the safety of foreign labor workers. The development and implementation of safety training programs do not always regularly take into account language barriers, low literacy levels, or cultural elements. This oversight can lead to more injuries and fatalities among this group. Despite established health and safety training programs, a significant number of non-native English speakers are injured or killed in preventable, occupation-related accidents. Introducing safety programs that use alternative teaching strategies such as pictograms, illustrations, and hands-on training opportunities will assist in addressing challenges for non-English laborers. Occupational health nursing has an opportunity to provide guidance on this subject and assist businesses in creating a safer and more productive work environment. © 2015 The Author(s).

The environment problems on global scale have been highlighted in addition to the local problems due to the rapid increase of population, the increase of energy demand and so on. The global environment summit was held in Brazil. Now, global environment problems are the problems for mankind, and their importance seems to increase toward 21st century. In such circumstances, cogeneration can reduce carbon dioxide emission in addition to energy conservation, therefore, attention has been paid as the countermeasure for global environment. The background of global environment problems is explained. As to the effectiveness of cogeneration for global environment, the suitability of city gas to environment, energy conservation, the reduction of carbon dioxide and nitrogen oxides emission are discussed. As for the state of spread of cogeneration, as of March, 1992, those of 2250 MW in terms of power generation capacity have been installed in Japan. It is forecast that cogeneration will increase hereafter. As the future systems of cogeneration, city and industry energy center conception, industrial repowering, multiple house cogeneration and fuel cells are described. (K.I.)

Multiple myeloma (MM) is an incurable plasma cell malignancy with a poorly understood etiology. The purpose of our research was to examine the relationships between lifetime occupations and MM in a relatively large case-control study. MM cases (n = 180) were identified through cancer registries in the Seattle-Puget Sound area and Detroit. Population-based controls (n = 481) were identified using random digit dialing and Medicare and Medicaid Services files. In-person interviews were conducted to ascertain occupational histories. Standard occupational classification (SOC) and standard industrial classification (SIC) codes were assigned to each job held by each participant. Unconditional logistic regression was used to generate odds ratios (ORs) and 95% confidence intervals (CIs) for associations between MM and having ever worked in each occupation/industry and according to duration of employment in an occupation/industry. The risk of MM was associated with several manufacturing occupations and industries, including machine operators and tenders, not elsewhere classified (SOC 76) (OR = 1.8, CI = 1.0-3.3); textile, apparel, and furnishing machine operators and tenders (SOC 765) (OR = 6.0, CI = 1.7-21); and machinery manufacturing, except electrical (SIC 35) (OR = 3.3, CI = 1.7-6.7). Several service occupations and industries, such as food and beverage preparation (SOC 521) (OR = 2.0, CI = 1.1-3.8), were also associated with MM. One occupation that has been associated with MM in several previous studies, painters, paperhangers, and plasterers (SOC 644) was associated with a non-significantly elevated risk (OR = 3.6, CI = 0.7-19). We found associations between the risk of MM and employment in several manufacturing and service-related occupations and industries. Copyright 2010 Wiley-Liss, Inc.

Occupational Safety and Health in Venezuela.

Venezuela has pioneered a preventive-focused and comprehensive movement for Occupational Safety and Health (OSH) in Latin America. However, despite being an oil-rich country, it has some of the lowest salaries for their workers and highest levels of hyperinflation, devaluation, crime, and violence of the world. Review the current status and challenges on relevant aspects of OSH in Venezuela. Review of literature and documents from national governments, UN agencies, NGOs, and the Venezuelan government concerning OSH and related topics since 1986. Reformed in 2005, the Organic Law on Prevention, Conditions and Environment (LOPCYMAT) was a fundamental moment of change for OSH. Factors which have impacted OSH the strongest are (i) the creation of the National Institute of Occupational Safety and Health (INPSASEL) and (ii) the socioeconomic crisis Venezuela is going through. Venezuela's laws are innovative and yet non-compliance is enormous. Almost half of the population works in the informal sector. Following the International Labor Office projections, 5 people die per day in Venezuela due to occupational accidents or diseases, making health and safety at work a luxury rather than a right. The quality of life for the average worker has deteriorated, affecting not only health but the overall well-being of all Venezuelans. The political and socio-economic situation has led to a mass exodus of more than 1.6 million highly qualified and talented professionals. Many statistics concerning OSH are not updated and are unreliable regarding occupational accidents and diseases. There is a substantial difference between what is written to protect individual Venezuelans in the workplace and the reality of workplace conditions. Substantial governmental actions are needed in the immediate future to improve occupational safety and health of Venezuelan workers. Copyright © 2015 The Author. Published by Elsevier Inc.

Occupant traffic estimation through structural vibration sensing

2016-04-01

The number of people passing through different indoor areas is useful in various smart structure applications, including occupancy-based building energy/space management, marketing research, security, etc. Existing approaches to estimate occupant traffic include vision-, sound-, and radio-based (mobile) sensing methods, which have placement limitations (e.g., requirement of line-of-sight, quiet environment, carrying a device all the time). Such limitations make these direct sensing approaches difficult to deploy and maintain. An indirect approach using geophones to measure floor vibration induced by footsteps can be utilized. However, the main challenge lies in distinguishing multiple simultaneous walkers by developing features that can effectively represent the number of mixed signals and characterize the selected features under different traffic conditions. This paper presents a method to monitor multiple persons. Once the vibration signals are obtained, features are extracted to describe the overlapping vibration signals induced by multiple footsteps, which are used for occupancy traffic estimation. In particular, we focus on analysis of the efficiency and limitations of the four selected key features when used for estimating various traffic conditions. We characterize these features with signals collected from controlled impulse load tests as well as from multiple people walking through a real-world sensing area. In our experiments, the system achieves the mean estimation error of +/-0.2 people for different occupant traffic conditions (from one to four) using k-nearest neighbor classifier.

An Important Psychosocial Risk in Occupational Health: Mobbing

Directory of Open Access Journals (Sweden)

Hulya Gul

2009-12-01

Full Text Available Mobbing, a rising issue in the occupational health area, has recently been paid attention more and more in the academic and business settings. Mobbing is a series of action having multidimensional features socially and psychologically, and it is frequent in occupational environment. Mobbing may present itself as behaviors, words, acts, gestures, or writings that affect personality, dignity, physical, and psychological integrity. Early 1990’s were the time studies about mobbing started to be done, indicating its negative effects on both individual and the working place. These extend from stress and depression to psychosomatic disorders, and even chronicle diseases and cardiovascular problems. Workplace mobbing is repetitive, unreasonable malicious behavior directed toward an employee or a group of employees, that creates risk to health and safety. It may manifest as intimidation, physical violence, discrimination, threats, social isolation, and destabilization. The most prominent result is lack of continuity. Organizational problems, time pressure, lack of leadership and task definition etc. are defined to be potential risk factors. For prevention, there must be an organized intervention including a strategically approach towards mobbing and a positive environment at workplace. There is a need for standardization, and studies to define and evaluate mobbing behavior in order to make a comparison between different cultures and occupations. In this review article mobbing was examined with the view of public health. [TAF Prev Med Bull 2009; 8(6.000: 515-520

2006-01-01

This pilot study evaluated the effectiveness of energy conservation training to help post-therapy cancer survivors manage their fatigue. Twelve post-therapy cancer survivors were randomly assigned to an energy conservation training or usual care control (6 in each group). Participants in the intervention group received 1 to 2 hours of individual, face-to-face energy conservation training from an occupational therapist followed by once-a-week telephone monitoring sessions in the subsequent three weeks. Participants in the control group received standard care from their oncologist. Analysis of pre- and post-training data from the Piper Fatigue Scale (PFS) revealed significant reduction only in the sensory subscale of the PFS (Z = 2.21; p = 0.027) for the intervention group; but no significant reduction in the four subscale or total scores of the PFS for the control group. Findings demonstrate partial support for the effectiveness of energy conservation training in helping post-therapy cancer survivors manage their fatigue. Energy conservation training seems to be a viable strategy for managing cancer-related fatigue, though its efficacy is modest. Incorporating specific energy restoration strategies such as relaxation and meditation for future research may help advance the growing body of knowledge in symptom management for post-therapy cancer survivors.

Enlightening Butterfly Conservation Efforts: The Importance of Natural Lighting for Butterfly Behavioral Ecology and Conservation

2018-01-01

Light is arguably the most important abiotic factor for living organisms. Organisms evolved under specific lighting conditions and their behavior, physiology, and ecology are inexorably linked to light. Understanding light effects on biology could not be more important as present anthropogenic effects are greatly changing the light environments in which animals exist. The two biggest anthropogenic contributors changing light environments are: (1) anthropogenic lighting at night (i.e., light pollution); and (2) deforestation and the built environment. I highlight light importance for butterfly behavior, physiology, and ecology and stress the importance of including light as a conservation factor for conserving butterfly biodiversity. This review focuses on four parts: (1) Introducing the nature and extent of light. (2) Visual and non-visual light reception in butterflies. (3) Implications of unnatural lighting for butterflies across several different behavioral and ecological contexts. (4). Future directions for quantifying the threat of unnatural lighting on butterflies and simple approaches to mitigate unnatural light impacts on butterflies. I urge future research to include light as a factor and end with the hopeful thought that controlling many unnatural light conditions is simply done by flipping a switch. PMID:29439549

of office buildings? Within the DRM research framework, explorative design case studies, systematic literature reviews, expert interviews, observation case studies, and experimentation research methods were employed, in order to develop design guidelines, high performance space types and case studies, as well as assessments of the hypotheses of several experiments. For instance, as part of the investigation of the first sub research question, a design case study was conducted that evaluated the potential of microforests to reduce the energy consumption rates of office buildings, both in terms of the potential of vegetation to function as a shading device, and in terms of the potential energy savings that can be attained through the provision of semi-outdoor, high quality microforest workspaces. The results of this study, which are discussed in Chapter 4, indicate that vegetation can be as effective, or more effective, than typical shading devices, in terms of shading effectiveness. Moreover, in terms of economic performance, this study found that improving occupant work performance provided substantially greater economic benefits than reducing the energy costs of the mid-size commercial office building. This finding indicates that, in terms of economic performance, design teams should be focused on designing office environments that improve worker performance. Thus, the results of this case study indicate that economic and worker performance are interrelated. In order to investigate the potential effects of microforests on occupant thermal comfort, a quasi-experiment which evaluated the potential psychological and physiological impacts of microforests on occupant thermal comfort, was conducted. This study is discussed in Chapter 5. The results of this study indicate that working within a densely vegetated work environment, such as a microforest, improves occupant thermal comfort, both in normal and more extreme temperatures, throughout the four seasons. Thus, the

Full Text Available Purpose - Play occupation has been identified as an essential part of children’s lives, and it subsequently features in paediatric occupational therapy. However, few studies address the current place of play and play occupation in occupational therapy practice. This study aims to address this gap in knowledge by exploring paediatric occupational therapists’ perspectives on the place of play and play occupation in occupational therapy practice in Ireland. Design/methodology/approach - A cross-sectional online survey was conducted to gather data about the current use of play in the occupational therapy for children under 12 years. Convenience sampling and snowball recruitment techniques were used to recruit paediatric occupational therapists. Data were analysed using descriptive statistics and qualitative content analysis. Findings - In total, 65 therapists responded to the survey (estimated response rate, 32%. Results are organised into four sections: demographics and practice context, play assessment practices, use of play in practice and perceived barriers to play-centred practice. Respondents reported that they valued play as a childhood occupation. However, the survey findings identified that the primary focus was on play as a means to an end. Lack of education on play (research, theory and interventions and pressures in the workplace have been identified as barriers to play-centred practice. Research limitations/implications - Findings indicate that there is a mismatch between therapists valuing play as an occupation and how play is used in occupational therapy practice. Unless clarifications are made about play occupation as being different to skills acquisition in childhood, play occupation will continue to get overlooked as an authentic concern of occupation-centred practice. Thus, play as occupation deserves further attention from educators, researchers and practitioners as a means of strengthening occupation-centred practice, in

Bradshaw, Michelle L

2016-01-01

The purpose of this study was to establish a baseline description of American occupational therapy educators' knowledge, attitudes, and personal use of complementary and alternative medicine (CAM) as a first step in exploring the larger issue of future occupational therapy practitioners' preparedness for meeting clients' occupational needs in today's evolving healthcare environment. Results of this cross-sectional survey highlighted limitations of occupational therapy educators' knowledge of common CAM concepts and therapies across all demographic variables, varying attitudes towards CAM in general and its inclusion in occupational therapy education, and personal use of common CAM therapies. Without increased occupational therapy educator knowledge about CAM and engagement in the current healthcare practices, occupational therapy practitioners are at risk for having a limited role in integrative healthcare.

Personal 8-h shift exposure to respirable dust, diesel engine exhaust emissions (DEEE) (as respirable elemental carbon), and respirable crystalline silica of workers involved in constructing an underground metro railway tunnel was assessed. Black carbon (BC) concentrations were also assessed using a MicroAeth AE51. During sprayed concrete lining (SCL) activities in the tunnel, the geometric mean (GM) respirable dust exposure level was 0.91mg m(-3), with the highest exposure measured on a back-up sprayer (3.20mg m(-3)). The GM respirable crystalline silica concentration for SCL workers was 0.03mg m(-3), with the highest measurement also for the back-up sprayer (0.24mg m(-3)). During tunnel boring machine (TBM) activities, the GM respirable dust concentration was 0.54mg m(-3). The GM respirable elemental carbon concentration for all the TBM operators was 18 µg m(-3); with the highest concentration measured on a segment lifter. The BC concentrations were higher in the SCL environment in comparison to the TBM environment (daily GM 18-54 µg m(-3) versus 3-6 µg m(-3)). This small-scale monitoring campaign provides additional personal data on exposures experienced by underground tunnel construction workers. © The Author 2015.

The Portrayal of Occupational Therapy and Occupational Science in Canadian Newspapers: A Content Analysis

Directory of Open Access Journals (Sweden)

Tsing-Yee (Emily Chai

2016-05-01

Full Text Available The primary goal of occupational therapy is to enable people to participate in the activities of everyday life. The demand for occupational therapists in Canada is expected to grow sharply at an annual growth rate of 3.2%, compared to 0.7% for all occupations. At the same time, it is believed by occupational therapists in Canada that the Canadian public does not understand the role of occupational therapy. Occupational science is an emerging basic science field that supports the practice of occupational therapy. Given that newspapers are one source the public uses to obtain information and that newspapers are seen to shape public opinions, the purpose of this study is to investigate how “occupational therapy” is covered in Canadian newspapers from the term’s first appearance in 1917 until 2016 and how “occupational science” is covered from the term’s first appearance in 1989 to 2016. We interrogated the findings through the lens of three non-newspaper sources—two academic journals: Canadian Journal of Occupational Therapy (CJOT and Journal of Occupational Science (JOS; and one Canadian magazine: Occupational Therapy Now (OTN. We found that medical terms were prevalent in the newspaper articles covering occupational therapy similar to the presence of medical terms in the CJOT and OTN. However, the newspapers missed contemporary shifts in occupational therapy as evident in the CJOT, OTN and JOS—such as the increased engagement with enablement, occupational justice and other occupational concepts. The newspapers also failed to portray the societal issues that occupational therapy engages with on behalf of and with their clients, and the newspapers did not cover many of the client groups of occupational therapy. Occupational science was only mentioned in n = 26 articles of the nearly 300 Canadian newspapers covered with no concrete content linked to occupational science. The scope of occupational therapy presented in Canadian

The Development of a Design and Construction Process Protocol to Support the Home Modification Process Delivered by Occupational Therapists

Directory of Open Access Journals (Sweden)

Rachel Russell

2018-01-01

Full Text Available Modifying the home environments of older people as they age in place is a well-established health and social care intervention. Using design and construction methods to redress any imbalance caused by the ageing process or disability within the home environment, occupational therapists are seen as the experts in this field of practice. However, the process used by occupational therapists when modifying home environments has been criticised for being disorganised and not founded on theoretical principles and concepts underpinning the profession. To address this issue, research was conducted to develop a design and construction process protocol specifically for home modifications. A three-stage approach was taken for the analysis of qualitative data generated from an online survey, completed by 135 occupational therapists in the UK. Using both the existing occupational therapy intervention process model and the design and construction process protocol as the theoretical frameworks, a 4-phase, 9-subphase design and construction process protocol for home modifications was developed. Overall, the study is innovative in developing the first process protocol for home modifications, potentially providing occupational therapists with a systematic and effective approach to the design and delivery of home modification services for older and disabled people.

The construction sector is associated with various accidents and fatal injuries. These occupational accidents are caused by numerous factors, such as lack of supervision; lack of adherence to safe work technique; failure to wear personal protective equipment; and failure to comply with the safe use of tools, vehicles, and machines. Using 2013–2016 secondary data from the Department of Occupational Safety and Health and Social Security Organization, this study conducted a descriptive exploration survey to identify common fatal occupational injuries associated with the Malaysian construction sector, as well as their causes and accidental agents. Results indicated that construction, followed by manufacturing, agriculture, forestry, logging, and fishery, are the riskiest job sectors in Malaysia. The highest incidences of occupational casualties were reported in Sarawak, Johor, and Selangor. These states accounted for approximately 13.33% to 18.18% of all cases of fatal occupational accidents. In these states, the lack of safety and health regulations and poor execution of risk management increased the risk of occupational accidents. Falls from heights accounted for 46.28% of fatal occupational injuries. Furthermore, being crushed by objects, materials, or vehicles accounted for 9.09% to 17.36% of fatal occupational injuries. Substandard work environment and transportation and lifting equipment, such as scaffolds, are primary accidental agents. Results of this study could enhance the knowledge and awareness of construction workers and management of job-related injuries to decrease the incidence of fatal occupational accidents.

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

Conservative and non-conservative behaviour of radionuclides in an estuarine environment, with particular respect to the behaviour of plutonium isotopes

International Nuclear Information System (INIS)

Assinder, D.J.; Kelly, M.; Aston, S.R.

1984-01-01

Of the radionuclides entering the Esk Estuary from the Sellafield effluent discharges into the Irish Sea, the behaviour in the dissolved phase of 106 Ru, 134 Cs and 137 Cs is conservative whilst that of 238 Pu and sup(239,240)Pu is non-conservative. The latter leads to the enrichment of Pu in low salinity waters, probably by transfer from the particulate phase. This has repercussions on the distribution of Pu activity in the estuary, and also on the long term fate of sediment stored Pu. (author)

Based on building energy and indoor environment simulations, this study uses a recently developed method relying on Bayesian Network theory to estimate and compare the consequences for occupant performance and energy consumption of applying temperature criteria set according to the adaptive model...... configurations, especially in the tropical climate, the estimated performance differed only modestly between configurations. However, energy consumption was always lower in buildings without mechanical cooling, particularly so in the tropical climate. The findings indicate that determining acceptable indoor...... thermal environments with the adaptive comfort model may result in significant energy savings and at the same time will not have large consequences for the mental performance of occupants....

Full Text Available Occupation, understood as an activity with a sense in which the person participates daily and can be named by the culture, is what gives meaning to our live. In the Spanish region of Galicia, people who work in deep-sea fishingfeel that the remoteness of their homes and the conditions under which occurs the workplace,could constrain aspects related to their occupational performance and therefore their occupation. This original research article’s main aim is to know the experience of occupational performance of people working in a productive activity offshore.The methodology is a qualitative type, based on a phenomenological study, within an interpretive paradigm. They have been used as data collection techniques, in-depth interviews and field notebook. The total number of respondents was 21 people aged between 24 and 57 years old. The main results of this study refer to the consequences of environment in the occupational performance of the protagonists. Both aspects are present in speeches and related with extrinsic and intrinsic work developed by the protagonists of the study. As for the conclusions, we have identified changes in the management of the occupation producing an impact on both the individual and the family structure; all motivated by the productive activity developed.

A historical and socioeconomic analysis of occupational safety and health in India.

Science.gov (United States)

Vilanilam, J V

1980-01-01

Workers in poor countries of the so-called Third World are more likely to be affected by the dangers of high technology than their counterparts in wealthier countries. Owing to their lack of education, most workers in the "developing" world are unaware of the hazards of their occupations. Moreover, their general backwardness in sanitation and nutrition and climatic proneness of their geographic region to epidemics cause diseases contracted from the work environment to be aggravated. occupational diseases are often misconstrued as diseases resulting from the general environment. Since unemployment in underdeveloped countries is of a very high order, workers are prepared to accept any job, irrespective of the dangers involved. Labor is cheap and easily replaceable, so employers see no need for improving occupational safety and health. Labor unions are mostly controlled by full-time politicians who consider health a political issue, especially when their party controls the country's government. The seriousness of all these factors is heightened by the existing socioeconomic order in poor countries, in which national medievalism and multinational modernism play a crucial role. In order to understand the prevailing socioeconomic order, one has to analyze the social structures of poor countries in the context of today's world economic structure. India is taken as an example of a "developing" country where all the above-mentioned factors and many others are in operation: backwardness of the worker; poor nutrition; lack of concern for public health; proneness to epidemics; and indifference on the part of employers, politicians, and unions toward occupational health; high unemployment, control of the local economy by multinational corporations; and control of the mass media by feudalistic vested interests. This article attempts to analyze the occupational health and safety issue in India from a historical perspective, and stresses the vital need of structural changes in

New technologies continue to be introduced into the workplace and the environment. These novel technologies also bring in new hazards leading to evolving patterns of established occupational and environmental diseases, as well as novel conditions never before encountered. Many of these emerging conditions have appeared in media outlets or in the literature as case reports. These sentinel cases often serve as a warning sign for subsequent outbreaks. This review will discuss environmental and occupational lung diseases and exposures from a global perspective. These diseases and exposures include environmental exposure to asbestos and lung diseases, accelerated silicosis in sandblasting jean workers, coal worker's pneumoconiosis in surface coal miners, health effects of indoor air pollution from burning of biomass fuels and exposures to heavy metals and potential health effects from hydraulic fracturing (fracking). Other emerging conditions are also discussed, including smog in developing countries, sand storms in Asia and the Middle East and respiratory illnesses from nanoparticles and man-made fibres. Clinicians must remain vigilant for potential occupational and environmental exposures, especially when evaluating patients with unusual and unique presentation, so that occupational and environmental risk factors may be identified, and monitoring and preventive measures can be implemented early.

The Indo-Dutch Environmental & Sanitary Engineering Project under the Ganga action Plan in Kanpur and Mirzapur is being executed within the Indo-Dutch bilateral development cooperation framework. The project aims to integrate physical, social and health related improvements. It is expected that the development approach and methodology can be replicated in other urban settlements in India. The project is being supplemented by a training and institutional strengthening programme to facilitate the transfer of new technologies and improvement of operation and maintenance of the new facilities. The project is also aimed at the improvement of the living conditions of the population, by installing drinking water and drainage systems. A socio-economic unit in the project supports the technical interventions by enhancing the community to participate in project activities. The Occupational Health Programme in Jajmau, an industrial slum of Kanpur, aims to improve the working conditions of tannery workers. Four hundred and ninety-seven tannery workers and 80 employees not engaged in leather work, from 20 tanneries, were interviewed and underwent physical examination. The mean age of tannery workers was 32 years, about half of them recently migrated to Kanpur. The majority of the workers are illiterate, have temporary jobs and 85% have a monthly income between 300 and 600 Rs. Occupational morbidity was 28.2%. Regular meetings with tannery owners, the training of tannery workers in first aid, and support for the installation of safety and health councils in tanneries are the main programme activities.(ABSTRACT TRUNCATED AT 250 WORDS)

2015-03-01

The paper discusses some of the new driving forces, new international programs, and new potential partners in soil conservation. Increasingly, international efforts to mitigate land degradation are shifting from studies of the biophysical processes to improving the global, national and local enabling policy environment, as well as mainstreaming of soil conservation into national and regional policies and programs. Also, increased emphasis is placed on economic instruments and international markets, such as carbon trading, and incorporation of non-market values in ecosystem investment, such as payment for ecosystem services, certification schemes, etc. The paper discusses some of the opportunities for soil conservation that accrue from these new driving forces.

Exploring the role of occupational therapy in caring for cancer survivors in Australia: A cross sectional study.

Science.gov (United States)

Buckland, Nicole; Mackenzie, Lynette

2017-10-01

With increasing rates of cancer survival in Australia, more people are living with long-term side effects of cancer and its treatment, and cancer survivorship is now considered a distinct phase of cancer care. While occupational therapists play an integral role in multidisciplinary care for people with chronic conditions, there is little evidence documenting the occupational therapy role for people living with chronic cancer-related conditions. This study aimed to explore the views of Australian occupational therapists about current practice and what constitutes best practice for cancer survivors. A cross-sectional online survey was developed and distributed via emailed invitations to the Occupational Therapy Australia membership to collect responses from occupational therapists in a range of locations and practice settings around Australia. A total of 204 completed surveys were returned (response rate of 4%). More than 70% (n = 143) of respondents worked with people with cancer at least sometimes and most worked in acute (13.8%, n = 28) or community (11.2%, n = 23) settings. Participants rated equipment provision as the most common intervention (94%, n = 192), followed by energy conservation (91%, n = 185) and pressure care (78%, n = 160). Lack of funding for occupational therapy positions and a lack of recognition of the role of occupational therapy by health professionals and consumers were identified as key barriers to survivorship care. Research is needed to provide evidence supporting the role and practice of occupational therapy with cancer survivors. Collaborative work with multidisciplinary teams is needed to develop long-term routine treatment pathways that include occupational therapy interventions. © 2017 Occupational Therapy Australia.

[Gender and job satisfaction in stereotypical masculine and feminine occupations].

Lipińska-Grobelny, Agnieszka; Goździk, Iwona

2012-01-01

The purpose of this research was to analyze the relationship between gender and job satisfaction among employees involved in a stereotypical masculine (tram driver) and a stereotypical feminine occupation (nurse). It was expected that people with feminine gender schema would be more satisfied with their traditionally feminine occupations compared with those with masculine gender schema and vice versa. A group of 103 individuals, including 47 females (15 tram drivers and 32 nurses) and 56 males (41 tram drivers and 15 nurses) completed the following battery of instruments: The Bem Sex Role Inventory by Kuczyńska, Job Affect Scale by Brief, et al. Job Descriptions Questionnaire by Neuberger and Allerbeck. The results of the study showed that gender proved to be a variable that differentiates the level of job satisfaction (both overall satisfaction and satisfaction with different components) only as regards stereotypical feminine occupations. Moreover, individuals with feminine gender schema working in a stereotypical feminine occupation are more satisfied with co-workers and work conditions, and those with masculine gender schema involved in a stereotypical masculine occupation are more satisfied with a supervisor. The gender analysis can be an important tool for the recruitment and selection procedures and plays an essential role in assessing the person-environment fit.

Periodicity, duration, and function of occupation at Tauroa Point, Northland, New Zealand

International Nuclear Information System (INIS)

Allen, M.S.

2005-01-01

Three coastal sites at Tauroa Point, Northland, New Zealand were explored using varied archaeological techniques. At least seven, and possibly more, distinct occupations were identified, the earliest dating to about the fourteenth century AD. The analysis presented here centres on defining the periodicity, duration, and nature of pre-European Maori activities on this coast over time. Geomorphic evidence, radiocarbon dates, feature characteristics, fauna and artefact assemblages, and wood charcoal data are used in this endeavour. Indications are that the earliest occupation was the most extended, followed by repeated ephemeral visits between AD 1400 and 1650, and intensified but short-term coastal occupations after AD 1650. These occupations all took place within a geomorphically active environment, yet were variably affected by erosion and aggradation; in at least one locality the build-up of dune sands intensified after site abandonment.

Objective: To present and discuss the effect of occupational therapy intervention with a 70-year old patient diagnosed with PD. Method: This is an experience report with a single subject. An intervention plan including an exercise program for extra-care activities and home visits for observation of possible difficulties and risk of falls in the environment has been prepared. The measurement of independence was performed using the Functional Independence Measure-FIM. The intervention occurred during six months. Results: It was identified improvement in eating and writing activities. There was one score of improvement documented in FIM. Conclusion: The importance of the intervention of occupational therapy is enforced, which in this context improved the occupational performance of this subject in the daily life activities, contributing for maintaining functional performance.

Occupational therapy in Oman: the impact of cultural dissonance.

Science.gov (United States)

Al Busaidy, Najat Saif Mohammed; Borthwick, Alan

2012-09-01

Occupational therapy theory and philosophy are broadly considered to be based on Western cultural values. In contrast, the application of theory and practice in the Sultanate of Oman, historically based on traditional Middle Eastern and Islamic cultural values, provides a case exemplar, which highlights both paradigmatic differences and cultural dissonance. Drawing on the experiences of occupational therapists working in Oman, this study found that the application of therapeutic goals aimed at patient independence and autonomy were difficult to achieve in an environment where family duty and responsibility for care were highly prized. Dressing and cooking assessments were challenging, and issues related to gender proved problematic. Therapists found the need to adapt practice to acknowledge these differences, and to adopt pragmatic problem-solving strategies, without resolving the underpinning philosophical contradictions. Occupational therapy in Oman is under-researched; further work is needed to confirm the cross-cultural validity of specific assessments and practice models. Copyright © 2012 John Wiley & Sons, Ltd.

Conservation Documentation and the Implications of Digitisation

Directory of Open Access Journals (Sweden)

Michelle Moore

2001-11-01

Full Text Available Conservation documentation can be defined as the textual and visual records collected during the care and treatment of an object. It can include records of the object's condition, any treatment done to the object, any observations or conclusions made by the conservator as well as details on the object's past and present environment. The form of documentation is not universally agreed upon nor has it always been considered an important aspect of the conservation profession. Good documentation tells the complete story of an object thus far and should provide as much information as possible for the future researcher, curator, or conservator. The conservation profession will benefit from digitising its documentation using software such as databases and hardware like digital cameras and scanners. Digital technology will make conservation documentation more easily accessible, cost/time efficient, and will increase consistency and accuracy of the recorded data, and reduce physical storage space requirements. The major drawback to digitising conservation records is maintaining access to the information for the future; the notorious pace of technological change has serious implications for retrieving data from any machine- readable medium.

Mental health practice can create challenging environments for occupational therapists. This study explores the dynamic processes involved in the development and maintenance of professional resilience of experienced mental health occupational therapy practitioners. It presents the PRIOrity model that summarises the dynamic relationship between professional resilience, professional identity and occupation-based practice. A narrative inquiry methodology with two phases of interviews was used to collect the data from nine experienced mental health practitioners. Narrative thematic analysis was used to interpret the data. Professional resilience was linked to: (i) professional identity which tended to be negatively influenced in contexts dominated by biomedical models and psychological theories; (ii) expectations on occupational therapists to work outside their professional domains and use generic knowledge; and (iii) lack of validation of occupation-focussed practice. Professional resilience was sustained by strategies that maintained participants' professional identity. These strategies included seeking 'good' supervision, establishing support networks and finding a job that allowed a match between valued knowledge and opportunities to use it in practice. For occupational therapists professional resilience is sustained and enhanced by a strong professional identity and valuing an occupational perspective of health. Strategies that encourage reflection on the theoretical knowledge underpinning practice can sustain resilience. These include supervision, in-service meetings and informal socialisation. Further research is required into the role discipline-specific theories play in sustaining professional values and identity. The development of strategies to enhance occupational therapists' professional resilience may assist in the retention of occupational therapists in the mental health workforce. © 2012 The Authors Australian Occupational Therapy Journal © 2012

A major priority of the U.S. Department of Energy (DOE) is to ensure the health, safety, and security of DOE employees, contractors, and subcontractors. The Office of Health, Safety and Security (HSS) provides the corporate-level leadership and strategic vision necessary to better coordinate and integrate health, safety, environment, security, enforcement, and independent oversight programs. One function that supports this mission is the DOE Corporate Operating Experience Program that provides collection, analysis, and dissemination of performance indicators, such as occupational radiation exposure information. This analysis supports corporate decision-making and synthesizes operational information to support continuous environment, safety, and health improvement across the DOE complex.

The aim of this study was to assess by different approaches the occupational exposure during the remediation of a tailings dam in an abandoned uranium mining site, with an area of about 13.3 ha and an estimated volume of 1.39 million m³. A hypothetical scenario was created in which the workers involved in the remediation activities were exposed to radiation through both internal and external pathways. It was intended to assess quantitatively the potential exposure of the workforce involved in the remediation works, focussing particularly on the inhalation of radon and on the gamma irradiation from the contaminated soil. Different methodologies were considered based on a deterministic and a probabilistic approach for dose assessment and risk assessment, respectively. The deterministic approach typically employs a highly "conservative" single value for each input parameter. The probabilistic approach employs sensitivity and uncertainty analysis of input parameters using probabilistic distributions of the sensitive parameters. The results indicate that annual effective dose limit for occupational exposure (worst scenario case created) may reach a significant fraction of occupational radiation protection limits. This is also stressed by the values obtained for the occupational risk estimated by Monte Carlo methodology using probabilistic distributions for the input parameters. The results also showed that the pathway with the highest dose does not necessarily correspond to the pathway with the highest risk. Nevertheless, it is well known that probabilistic analysis generally produces more realistic results. Copyright © 2012 Elsevier Ltd. All rights reserved.

Full Text Available Background: Declining occupational sex segregation in the late 20th century helped to usher in unprecedented occupational and economic advancement for women. As the 21st century dawned, that advancement stalled. Objective: We examine how occupational integration occurred in the early decades of the 21st century by focusing on (1 the extent of occupational feminization and masculinization and (2 occupational succession. More broadly we examine how the representation of women in detailed occupational categories changed between 2000 and 2014, regardless of whether they were historically 'male' or 'female,' and how sociodemographic characteristics contributed to uneven shifts in occupational integration. Methods: We use Integrated Public Use Microdata Series data to estimate the percentage point female at the detailed occupation level, specifically the 5Š census microdata sample for 2000, and two 1Š American Community Survey (ACS samples for 2013 and 2014. Results: Despite a stall in overall integration, there was much fluctuation within detailed occupations. Moreover, occupational inroads have been uneven in the post-2000 period. Women gained entry into the same types of professional and managerial occupations they entered between 1970 and 2000, especially in the health professions. Men increased their representation in lower-level, nonprofessional occupations. Contribution: Rather than focus solely on predominantly male or female occupations, we focus more broadly on how occupations feminize and masculinize. More occupations masculinized than previously. Moreover, those in feminizing occupations are more likely to be advantaged (e.g., white, citizens, and educated, while those in masculinizing occupations are more likely to be disadvantaged (e.g., black, Hispanic, and poor English speakers.

The aquatic insect community is an important element for stream functionality and diversity, but the effects of altitude and conservation areas on the aquatic insect community have been poorly explored in neotropical ecozone. The lack of studies about the relative importance of space and environment on community structure is another obstacle within aquatic insect ecology, which precludes the inclusion of these studies in more current frameworks, like the metacommunity dynamics. We evaluated the relationship between the aquatic insect community structure at 19 streams in the Brazilian Cerrado and spatial and environmental variables, namely geographical distance among sites, stream altitude, chemical variables, and environmental protection areas. We partitioned the variance explained by spatial and environmental components using a partial redundancy analysis. The environment exhibited a strong spatial structure for abundance and number of genera, increasing these community parameters with elevated water conductivity. Only community composition had a large unexplained portion of variance, with a small portion constrained by environmental (altitude and conductivity) and spatial factors. A relevant point in the result was the streams with high conductivity were located outside of the conservation areas. These results suggest that the relationship between number of genera and abundance with environmental conditions is always associated with spatial configuration of streams. Our study shows that altitude is an important determinant of community structure, as it exerts indirect influences, and electrical conductivity directly determines community composition, and that some national parks may be inefficient in maintaining the diversity of aquatic insects in the Cerrado region.

Problems in the implementation of energy conservation measures. II. Consumer motivation

Energy Technology Data Exchange (ETDEWEB)

Phillips, P. H.

1977-10-15

During the course of 1975 a national survey of household attitudes to energy use and conservation was undertaken. The study suggested that while the public are generally in favor of energy conservation, they do not practice it. The study highlighted the need to do more than merely raise the level of awareness of the need for energy conservation. The energy intensive nature of our life-style was identified as a critical constraint on the implementations of effective voluntary energy conservation programs. It was suggested that our pattern of energy use is so deeply embedded in our everyday behaviors that it would take more than the presentation of information to produce the necessary changes in behavior. Some of the problems involved in attempting to motivate the consumer to conserve energy using either an extrinsic or instrinsic motivational approach are explored. A general model of the energy system is employed to illustrate that changes in the informational environment must be accompanied by changes in the institutional environment if pro-conservation attitudes are to be converted into conserving behavior. The case of personal transportation is used to indicate the need for a comprehensive package of measures which not only motivate the consumer but also facilitate and reinforce positive behavior if the dual goals of satisfying personal mobility needs and energy conservation are to be satisfied.

Of all work stressors, occupational stress is the leading cause of many disorders among workers. Drivers are classified as a high risk group for work related stress. This study set out to determine the relationship between risk factors of cardiovascular diseases and occupational stress among drivers. Two hundred and twenty two Ilam's intercity drivers were selected for the study. For measuring work stress, the Osipow work stress questionnaire was used. After a 10-h fasting period, systolic and diastolic blood pressure was recorded. Intravenous blood samples were taken to determine cholesterol, triglyceride and blood glucose levels. The independent samples t-test and Pearson's correlation test were used to assess the relationship between variables and occupational stress. Seventy-one percent of the intercity drivers suffered from average to acute stress, and 3.1% of them suffered from acute stress. There was no significant relationship between occupational stress and diastolic blood pressure (p = 0.254) among the drivers. Nevertheless, the Pearson's correlation test demonstrated a strong relationship between work stress and blood glucose (p stress were observed in the Ilam's intercity drivers. Occupational stress may have effect on blood glucose levels but the results did not suggest a considerable relationship between risk factors of cardiovascular diseases and occupational stress among intercity drivers.
