The need to train health social workers to practice interprofessionally is an essential goal of social work education. Although most health social workers have exposure to multidisciplinary practice within their field work, few social work education programs incorporate interprofessional learning as an integrated component of both course work and field experiences (McPherson, Headrick, & Moss, 2001; Reeves, Lewin, Espin, & Zwaranstein, 2010; Weinstein, Whittington, & Leiba, 2003). In addition, little is written about the kinds of curricula that would effectively promote interdisciplinary training for social work students. These findings are particularly puzzling since there is increasing and compelling evidence that interdisciplinary training improves health outcomes (IOM, 2001). This article describes a social work education program that incorporates an Interprofessional education and leadership curriculum for Maternal and Child Health Social Work (MCHSW) at the University of Maryland's School of Social Work. The University of Maryland's Interprofesisonal Training Model is described along with the components needed to formulate an interdisciplinary learning experience. Various outcomes and lessons learned are discussed.

Our aim was to describe construction-industry, work-related accident prevalence in, associated factors in, and potential impact on affiliated workers of the Mexican Institute of Social Security (Instituto Mexicano del Seguro Social, IMSS) in the Valley of Mexico. Prevalent cases in a retrospective case-control design. These include 385 construction-industry workers who were found to have construction work-related accidents in 2001. Controls comprised 385 active construction-industry workers without work-related accident background paired by gender, workplace, and worksite. Work-related accident prevalence in construction workers was 5.5%; most important risk factors and etiology fraction (Ef) included the following: age 16-20 years odds ratio, OR = 1.58, 95% confidence interval (95% CI) 1.40-10.7, p = 0.001, Ef 0.36; eventual insurance, OR = 3.7, 95% CI, 2.16-26.45, p = 0.001), Ef, 0.72, and no training for job, OR = 5.3, 95% CI, 4.9-69.2, p = 0.01), Ef: 0.81. Variables not showing significance were included salary, work shift, and workday. Work-related accident prevalence maintains its preponderance in the Valley of Mexico construction industry; identified risk factors are potentially modifiable, among which job training acquires unquestionable relevance.

Medical screening programs at three Departments of Energy (DOE) nuclear weapons facilities (Hanford Nuclear Reservation, Oak Ridge, and the Savannah River Site) have included audiometric testing since approximately 1996. This report summarizes hearing evaluations through March 31, 2003. Occupational examinations included a medical history, limited physical examination, and tests for medical effects from specific hazards, including audiometric testing. Hearing thresholds by frequency for DOE workers were compared to age-standardized thresholds among an external comparison population of industrial workers with noise exposures <80 dBA. Multivariate analyses were used to explore the risk of hearing impairment by duration of construction trade work and self-reported noise exposure, while controlling for potential confounders such as age, race, sex, smoking, elevated serum cholesterol, hypertension, solvent exposures, and recreational noise exposures. Hearing thresholds among DOE workers were much higher than observed in a comparison population of industrial workers with low noise exposures. Overall, 59.7% of workers examined were found to have material hearing impairment by NIOSH criteria. Age, duration of construction work, smoking, and self-reported noise exposure increased the risk of hearing loss. The risk of material hearing impairment was significantly elevated for construction trade workers compared to the external comparison population (odds-ratio = 1.6, 95% CI = 1.3-2.1) and increased with the duration of trade work. These medical screening programs confirm worker concerns about risks for hearing loss and the need for hearing conservation programs for construction workers, with emphasis on the prevention of noise exposures.

Blue-collar workers have a high risk of occupational contact dermatitis, but epidemiological studies are scarce. To investigate allergic contact dermatitis in blue-collar workers with dermatitis registered by the Danish Contact Dermatitis Group. A retrospective analysis of patch test data from 1471 blue-collar workers and 1471 matched controls tested between 2003 and 2012 was performed. A logistic regression was used to test for associations. The blue-collar workers often had occupational hand dermatitis (p < 0.001). Atopic dermatitis was less commonly observed among blue-collar workers (19.6%) than among controls (23.9%) (p = 0.005). Allergens with a statistically significant association with the occupational group of blue-collar workers were epoxy resins, methyldibromo glutaronitrile, 2-bromo-2-nitro-1,3-propanediol, potassium dichromate, and methylchloroisothiazolinone (MCI)/methylisothiazolinone (MI). The following occupations were additionally identified as risk factors for contact sensitization to MCI/MI and MI, epoxy resins, and potassium dichromate, respectively: painting, construction work, and tile setting/terrazzo work. Contact allergy is a major problem among blue-collar workers. The data indicate a healthy worker effect among blue-collar workers diagnosed with dermatitis, as blue-collar workers were diagnosed significantly less often with atopic dermatitis than were controls. © 2014 John Wiley & Sons A/S.

Multiple chronic health conditions have been associated with exposure to the September 11, 2001 World Trade Center (WTC) terrorist attacks (9/11). We assessed whether excess deaths occurred during 2003-2014 among persons directly exposed to 9/11, and examined associations of 9/11-related exposures with mortality risk. Deaths occurring in 2003-2014 among members of the World Trade Center Health Registry, a cohort of rescue/recovery workers and lower Manhattan community members who were exposed to 9/11, were identified via linkage to the National Death Index. Participants' overall levels of 9/11-related exposure were categorized as high, intermediate, or low. We calculated standardized mortality ratios (SMR) using New York City reference rates from 2003 to 2012. Proportional hazards were used to assess associations of 9/11-related exposures with mortality, accounting for age, sex, race/ethnicity and other potential confounders. We identified 877 deaths among 29,280 rescue/recovery workers (3.0%) and 1694 deaths among 39,643 community members (4.3%) during 308,340 and 416,448 person-years of observation, respectively. The SMR for all causes of death was 0.69 [95% confidence interval (CI) 0.65-0.74] for rescue/recovery workers and 0.86 (95% CI 0.82-0.90) for community members. SMRs for diseases of the cardiovascular and respiratory systems were significantly lower than expected in both groups. SMRs for several other causes of death were significantly elevated, including suicide among rescue recovery workers (SMR 1.82, 95% CI 1.35-2.39), and brain malignancies (SMR 2.25, 95% CI 1.48-3.28) and non-Hodgkin's lymphoma (SMR 1.79, 95% CI 1.24-2.50) among community members. Compared to low exposure, both intermediate [adjusted hazard ratio (AHR) 1.36, 95% CI 1.10-1.67] and high (AHR 1.41, 95% CI 1.06-1.88) levels of 9/11-related exposure were significantly associated with all-cause mortality among rescue/recovery workers (p-value for trend 0.01). For community members, intermediate (AHR 1.13, 95% CI 1.01-1.27), but not high (AHR 1.14, 95% CI 0.94-1.39) exposure was significantly associated with all-cause mortality (p-value for trend 0.03). AHRs for associations of overall 9/11-related exposure with heart disease- and cancer-related mortality were similar in magnitude to those for all-cause mortality, but with 95% CIs crossing the null value. Overall mortality was not elevated. Among specific causes of death that were significantly elevated, suicide among rescue/recovery workers is a plausible long-term consequence of 9/11 exposure, and is potentially preventable. Elevated mortality due to other causes, including non-Hodgkin's lymphoma and brain cancer, and small but statistically significant associations of 9/11-related exposures with all-cause mortality hazard warrant additional surveillance.

Screening cytomegalovirus infection in pregnant women is still controversial in 2004 in France. In this context, we evaluated the interest of such a screening in 2004 in France. This paper was designed to describe trends in CMV prenatal screening practices in 2000-2003 in France. This retrospective study, describes the prescription of CMV screening in HIV-negative pregnant women giving birth in the private care sector, according to their occupational category and geographical area. Data were provided by the "Caisse d'Assurance-maladie des Travailleurs Indépendants" (independent workers health insurance fund). The study included 34.347 women, delivering in 2001-2004 (beginning of pregnancy in 2000-2003). The number of pregnant women screened for CMV increased significantly between 2000 (5.8%, 301/5.177), 2001 (11.1%, 1.130/10.139) and 2002 (22.1%, 2.701/12.223), (p<0.001), then was stable in 2003 (22.0%, 1.496/6.808). The percentage of women screened for CMV, at least once during pregnancy, doubled between 2001 and 2002 (p<0.001) in each occupational category and geographical area. It was significantly different between occupational categories (p<0.01), with a higher percentage of women in the self-employed and commercial agent occupational categories than in the craftsman category. There was also a significant difference between geographical areas (p<0.001), with a higher rate in Paris. This study providing baseline information on CMV practices showed: 1- a significant increase in the frequency of CMV screening among pregnant women over the period 2000-2002 with a stabilization in 2003; 2- a similar trend observed in each occupation category and geographical area but with a markedly higher frequency of screening practices in the Paris area and among self-employed women. A study measuring the effect of the 2004 ANAES recommendation suggesting not to screen for CMV during pregnancy should be conducted.

Leptospirosis is an emerging infectious disease, with increasing frequency and severity of outbreaks, changing epidemiology of populations at risk, and the emergence of new serovars. Environmental drivers of disease transmission include flooding, urbanisation, poor sanitation, changes in land use and agricultural practices, and socioeconomic factors. In Queensland, human infection with Leptosira borgpetersenii serovar Arborea was first reported in 2001. This study aims to report the emergence of serovar Arborea in Queensland from 2001 to 2013, and investigate potential risk factors for infection and drivers of emergence. Data on laboratory-confirmed cases of human leptospirosis in Queensland were obtained from the enhanced surveillance system at the WHO/FAO/OIE Collaborating Centre for Reference and Research on Leptospirosis in Brisbane, Australia. The changing epidemiology of serovar Arborea from 2001 to 2003 was described with respect to case numbers, proportion of leptospirosis cases attributed to the serovar, and geographic distribution. Differences in risk factors for the most common serovars were compared. During this period, 1289 cases of leptospirosis were reported, including 233 cases attributed to serovar Arborea. Risk factors for infection include male gender (91 % of cases), occupation, and recreational exposure. Most common occupations recorded were banana workers (28.4 %), meat workers (7.2 %), dairy farmers (5.8 %), graziers/stockmen (5.5 %), 'other agricultural/rural workers' (16.4 %), and tourists or tourism operators (4.6 %). Time trend analysis showed that while non-Arborea cases decreased over the study period, Arborea cases increased by 3.4 cases per year. The proportion of annual cases attributed to Arborea peaked at 49 % in 2011 after unprecedented flooding in Queensland. Mapping of cases by residential location showed expansion of the geographic range of serovar Arborea, concentrating mostly around Brisbane, Cairns and Innisfail. Serovars varied significantly between ages and occupational groups, and serovar Arborea was most strongly associated with 'other agricultural/rural workers'. Leptospira borgpetersenii serovar Arborea has been emerging in Queensland since 2001, with increase in case numbers, the proportion of leptospirosis infections attributed to the serovar, as well as expansion of its geographic distribution. Reasons for this emergence are unknown, but climatic factors and environmental change are likely to have played important roles.

The construction sector has an important workforce for the country; however it is believed that this group of workers have inadequate healthy lifestyles. The aim of this study was to compare the clinical and para-clinical cardiovascular characteristics of these workers in 2 time periods. A retrospective study and analysis was performed using the medical records of 291 construction workers. The data collected included, sociodemographic variables, work, clinical and para-clinical details related to the cardiovascular status for the years 2011 and 2012. The mean age was 40.1 years, and mean body mass index was 26. In addition, 46% of workers were overweight and 15% obese. The annual increase in mean systolic blood pressure increased from 114.4 to 121.7mmHg (P=.000), and in diastolic pressure it increased from 72.8 to 79.5mmHg (P=.000), with the BMI increasing from 26 to 26.24 (P=.0000). The cholesterol levels ranged from 204.4 to 200.3mg/dl (P=.03) and triglycerides ranged from 175.6 to 208.2mg/dl (P=.0001). An annual increase was observed in several cardiovascular risk factors in construction workers in Colombia. An intervention is required for primary prevention focused on regular and quality education in these workers in order to mitigate cardiovascular risk and the presence of subsequent disease.

Background Studies have consistently documented declines in respiratory health after 11 September 2001 (9/11) among surviving first responders and other World Trade Center (WTC) rescue, recovery, and clean-up workers. Objectives The goal of this study was to describe the risk of newly diagnosed asthma among WTC site workers and volunteers and to characterize its association with WTC site exposures. Methods We analyzed 2003–2004 interview data from the World Trade Center Health Registry for workers who did not have asthma before 9/11 (n = 25,748), estimating the risk of newly diagnosed asthma and its associations with WTC work history, including mask or respirator use. Results Newly diagnosed asthma was reported by 926 workers (3.6%). Earlier arrival and longer duration of work were significant risk factors, with independent dose responses (p < 0.001), as were exposure to the dust cloud and pile work. Among workers who arrived on 11 September, longer delays in the initial use of masks or respirators were associated with increased risk of asthma; adjusted odds ratios ranged from 1.63 [95% confidence interval (CI), 1.03–2.56) for 1 day of delay to 3.44 (95% CI, 1.43–8.25) for 16–40 weeks delay. Conclusions The rate of self-reported newly diagnosed asthma was high in the study population and significantly associated with increased exposure to the WTC disaster site. Although we could not distinguish appropriate respiratory protection from inappropriate, we observed a moderate protective effect of mask or respirator use. The findings underscore the need for adequate and timely distribution of appropriate protective equipment and the enforcement of its use when other methods of controlling respiratory exposures are not feasible.

The construction industry is second only to agriculture in the annual number of fatal injuries in workers less than 18 years of age. We examined fatal injury reports for youth and adult workers to determine risk factors for injury and applicability of existing child labor regulations. The US Occupational Safety & Health Administration (OSHA) investigation data for fatal work injuries from 1984 through 1998 were reviewed with respect to type of event, employer characteristics, and apparent violations of existing child labor laws under the Fair Labor Standards Act (FLSA). We also examined whether the employer met exemption criteria for federal enforcement of child labor or OSHA regulations. The fatality rate for teenage construction workers age 19 and younger was 12.1 per 100,000 per year, slightly less than for adult workers. Teenage workers who were fatally injured were more likely than adults to have been employed at non-union construction firms (odds ratio (OR) = 4.96, P < 0.05), firms with fewer than 11 employees (OR = 1.72, P < 0.05), and their employers were more likely to have been cited by OSHA for safety violations (OR = 1.66, P < 0.05) than for firms which were investigated because of a fatality in an adult worker. Fatalities in teenagers were more likely to occur in special construction trades such as roofing. Among fatalities in workers less than 18 years of age, approximately one-half (49%) of the 76 fatal injuries were in apparent violation of existing child labor regulations. We estimated that in 41 of the 76 cases (54%) the employer's gross annual income exceeded the $500,000 threshold for federal enforcement of child labor laws. Only 28 of 76 cases (37%) were at construction firms with 11 or more employees, which are subject to routine OSHA inspections. Fatal injuries in teenage construction workers differed from those in adults in that they were more likely to be at small, non-union firms of which a substantial proportion were exempt from federal enforcement of child labor laws and from routine OSHA inspections. Safety programs for young construction workers should include small, non-union construction firms and those in special construction trades such as roofing. We did not identify specific areas for new regulation but the number of fatalities reviewed was small. Copyright 2003 Wiley-Liss, Inc.

Stream restoration practices are becoming increasingly common, but biological assessments of these improvements are still limited. Rock weirs, a type of constructed riffle, were implemented in the upper Cache River in southern Illinois, USA, in 2001 and 2003-2004 to control channel incision and protect high quality riparian wetlands as part of an extensive watershed-level restoration. Construction of the rock weirs provided an opportunity to examine biological responses to a common in-stream restoration technique. We compared macroinvertebrate assemblages on previously constructed rock weirs and newly constructed weirs to those on snags and scoured clay streambed, the two dominant substrates in the unrestored reaches of the river. We quantitatively sampled macroinvertebrates on these substrates on seven occasions during 2003 and 2004. Ephemeroptera, Plecoptera, and Trichoptera (EPT) biomass and aquatic insect biomass were significantly higher on rock weirs than the streambed for most sample periods. Snags supported intermediate EPT and aquatic insect biomass compared to rock weirs and the streambed. Nonmetric multidimensional scaling (NMDS) ordinations for 2003 and 2004 revealed distinct assemblage groups for rock weirs, snags, and the streambed. Analysis of similarity supported visual interpretation of NMDS plots. All pair-wise substrate comparisons differed significantly, except recently constructed weirs versus older weirs. Results indicate positive responses by macroinvertebrate assemblages to in-stream restoration in the Cache River. Moreover, these responses were not evident with more common measures of total density, biomass, and diversity.

Purpose: The patterns of care study (PCS) of radiotherapy for cervical cancer in Japan over the last 10 years was reviewed. Methods and Materials: The Japanese PCS working group analyzed data from 1,200 patients (1995-1997, 591 patients; 1999-2001, 324 patients; 2003-2005, 285 patients) with cervical cancer treated with definitive radiotherapy in Japan. Results: Patients in the 2001-2003 survey were significantly younger than those in the 1999-2001 study (p < 0.0001). Histology, performance status, and International Federation of Gynecology and Obstetrics stage were not significantly different among the three survey periods. Use of combinations of chemotherapy has increased significantly during thosemore » periods (1995-1997, 24%; 1999-2001, 33%; 2003-2005, 54%; p < 0.0001). The ratio of patients receiving concurrent chemotherapy has also dramatically increased (1995-1997, 20%; 1999-2001, 54%; 2003-2005, 83%; p < 0.0001). As for external beam radiotherapy (EBRT), the application rate of four-field portals has greatly increased over the three survey periods (1995-1997, 2%; 1999-2001, 7%; 2003-2005, 21%; p < 0.0001). In addition, the use of an appropriate beam energy for EBRT has shown an increase (1995-1997, 67%; 1999-2001, 74%; 2003-2005, 81%; p = 0.064). As for intracavitary brachytherapy (ICBT), an iridium source has become increasingly popular (1995-1997, 27%; 1999-2001, 42%; 2003-2005, 84%; p < 0.0001). Among the three surveys, the ratio of patients receiving ICBT (1995-1997, 77%; 1999-2001, 82%; 2003-2005, 78%) has not changed. Although follow-up was inadequate in each survey, no significant survival differences were observed (p = 0.36), and rates of late Grade 3 or higher toxicity were significantly different (p = 0.016). Conclusions: The Japanese PCS has monitored consistent improvements over the past 10 years in the application of chemotherapy, timing of chemotherapy, and EBRT methods. However, there is still room for improvement, especially in the clinical practice of ICBT.« less

World Bank oil-pipeline project designed to prevent HIV transmission.

PubMed

Kigotho, A W

1997-11-29

A World Bank-funded oil pipeline project, in Chad and Cameroon, is the first large-scale construction project in sub-Saharan Africa to incorporate an HIV/AIDS prevention component. The project entails the development of oil fields in southern Chad and construction of 1100 km of pipeline to port facilities on Cameroon's Atlantic coast. 3000 construction workers from the two countries will be employed between 1998 and 2001, including about 600 truck drivers. In some areas along the pipeline route, 50% of the prostitutes (who are frequented by truck drivers) are HIV-infected. The HIV/AIDS intervention aims to prevent HIV and sexually transmitted diseases (STDs) among project workers through social marketing of condoms, treatment of STDs in prostitutes along the route, and health education to modify high-risk behaviors. The program is considered a test case for African governments and donors interested in whether the integration of a health component in major construction projects can avoid AIDS epidemics in affected countries.

This study aims to describe workers who were hospitalized with work-related burn injuries and their psychiatric sequelae in Washington State. Psychiatric sequelae of interest were depression, posttraumatic stress disorder, and other anxiety disorders. Workers' compensation claims meeting a definition for a hospitalized burn patient from Washington State from January 2001 through April 2008 were analyzed. The resulting claims were searched for the presence of certain psychiatric diagnoses or treatment codes, and descriptive analyses performed. In Washington State during the time period, the prevalence of claims with psychiatric diagnoses after hospitalization with burn injury was 19%. Claims with psychiatric diagnoses had higher medical costs and more days of time loss than those without these diagnoses. Workers with electrical burns in the construction industry and in construction and extraction occupations had a higher proportion of psychiatric sequelae. Burns are devastating yet preventable injuries. Workers who were hospitalized with work-related burn injuries, particularly those in certain industries and occupations and those with electrical burns, are at high risk for developing serious psychiatric sequelae with major costs to both the individual and the society.

Indicators generally used to describe the work accident risk, i.e. frequency and injuries severity, are not suitable for comparison among single companies in order to point out those with major risk. We propose a method to draw out construction companies with higher risk of occupational injuries in the period 2003-2005 from INAIL-ISPESL-Regioni database. These companies will be object of specific interventions for the prevention, training and supervision from Prevention and Safety in Working Environments Services, from Provincial Labor Directions and Provincial Territorial Construction Committees.

Abstract Objective: To identify key factors associated with poor asthma control among adults in the World Trade Center (WTC) Health Registry, a longitudinal study of rescue/recovery workers and community members who were directly exposed to the 2001 WTC terrorist attacks and their aftermath. Methods: We studied incident asthma diagnosed by a physician from 12 September 2001 through 31 December 2003 among participants aged ≥18 on 11 September 2001, as reported on an enrollment (2003–2004) or follow-up questionnaire. Based on modified National Asthma Education and Prevention Program criteria, asthma was considered controlled, poorly-controlled, or very poorly-controlled at the time of a 2011–2012 follow-up questionnaire. Probable post-traumatic stress disorder, depression, and generalized anxiety disorder were defined using validated scales. Self-reported gastroesophageal reflux symptoms (GERS) and obstructive sleep apnea (OSA) were obtained from questionnaire responses. Multinomial logistic regression was used to examine factors associated with poor or very poor asthma control. Results: Among 2445 participants, 33.7% had poorly-controlled symptoms and 34.6% had very poorly-controlled symptoms in 2011–2012. Accounting for factors including age, education, body mass index, and smoking, there was a dose–response relationship between the number of mental health conditions and poorer asthma control. Participants with three mental health conditions had five times the odds of poor control and 13 times the odds of very poor control compared to participants without mental health comorbidities. GERS and OSA were significantly associated with poor or very poor control. Conclusions: Rates of poor asthma control were very high in this group with post-9/11 diagnosed asthma. Comprehensive care of 9/11-related asthma should include management of mental and physical health comorbidities. PMID:25539137

The Reconstruction and Analysis of Gene Regulatory Networks.

In post-genomic era, an important task is to explore the function of individual biological molecules (i.e., gene, noncoding RNA, protein, metabolite) and their organization in living cells. For this end, gene regulatory networks (GRNs) are constructed to show relationship between biological molecules, in which the vertices of network denote biological molecules and the edges of network present connection between nodes (Strogatz, Nature 410:268-276, 2001; Bray, Science 301:1864-1865, 2003). Biologists can understand not only the function of biological molecules but also the organization of components of living cells through interpreting the GRNs, since a gene regulatory network is a comprehensively physiological map of living cells and reflects influence of genetic and epigenetic factors (Strogatz, Nature 410:268-276, 2001; Bray, Science 301:1864-1865, 2003). In this paper, we will review the inference methods of GRN reconstruction and analysis approaches of network structure. As a powerful tool for studying complex diseases and biological processes, the applications of the network method in pathway analysis and disease gene identification will be introduced.

Estimate the associations between potential risk factors and HIV prevalence, as well as the trends from 2001 through 2007 of these indicators. Describe the vulnerability of female sex workers to in Guinea. Female sex workers in Guinea were interviewed in 2001 (n = 339) and 2007 (n = 598) and then screened for HIV. This was a nationwide survey using a unique protocol. Associations between potential risk factors and HIV prevalence were tested, and their trends from 2001 through 2007 estimated, after adjustment using Generalized Estimating Equations. In 2001, HIV was associated with illiteracy (PR = 1.41; p = 0.2), and with genital ulcer symptom (PR = 1.89; p = 0.001). In 2007, it was associated with illiteracy (RP = 1, p = 0.03), and with older age (PR for 10 years = 1.29; p = 0.004). The profile of illiterate female sex workers included low price per sexual encounter in both 2001 and 2007, greater number of clients, and lesser exposure to HIV/Aids counselling in 2001. From 2001 to 2007, increases were noted for the number of clients by female sex workers (p < 0.0001), price per sexual encounter (p < 0.0001), condom use (p < 0.0001) and exposure to HIV/Aids counselling (p < 0.0001); decreases were noted for symptoms of sexually transmitted diseases (p < 0.0001) and HIV prevalence among female sex workers aged less than 20 years (p = 0.005). From 2001 through 2007, condom use and exposure to HIV/Aids counselling increased in Guinea while symptoms of sexually transmitted diseases and HIV prevalence declined. Nevertheless, illiterate female sex workers remained highly vulnerable. Copyright 2010 Elsevier Masson SAS. All rights reserved.

The Occupational Health Internship Program (OHIP) was initiated in 2003 to recruit a new, diverse generation of occupational safety and health (OSH) professionals and to advance OSH within union and community-based initiatives. It retains the principles of the original OCAW/Montefiore internship program while adapting to the changed landscape of the 21st-century workplace. Case studies of OHIP projects illustrate how students have contributed to key OSH policies-to regulate silica exposure among construction workers, apply principles of green chemistry with Vietnamese nail salon workers, and integrate OSH into "green" jobs in the recycling industry. They have supported innovative campaigns with immigrant workers in contingent jobs-from taxi drivers to warehouse workers. The students, in turn, have been inspired to enter the OSH arena as professionals and worker advocates with the potential to contribute new energy to an OSH movement.

Group-based trajectory modeling was used to explore empirical trajectories of symptoms of posttraumatic stress disorder (PTSD) among 17,062 adult area residents/workers (nonrescue/recovery workers) enrolled in the World Trade Center (WTC) Health Registry using 3 administrations of the PTSD Checklist (PCL) over 9 years of observation. Six trajectories described PTSD over time: low-stable (48.9%), moderate-stable (28.3%), moderate-increasing (8.2%), high-stable (6.0%), high-decreasing (6.6 %), and very high-stable (2.0%). To examine factors associated with improving or worsening PTSD symptoms, groups with similar intercepts, but different trajectories were compared using bivariate analyses and logistic regression. The adjusted odds of being in the moderate-increasing relative to the moderate-stable group were significantly greater among enrollees reporting low social integration (OR = 2.18), WTC exposures (range = 1.34 to 1.53), job loss related to the September 11, 2001 disaster (OR = 1.41), or unmet mental health need/treatment (OR = 4.37). The odds of being in the high-stable relative to the high-decreasing group were significantly greater among enrollees reporting low social integration (OR = 2.23), WTC exposures (range = 1.39 to 1.45), or unmet mental health need/treatment (OR = 3.42). The influence of severe exposures, scarce personal/financial resources, and treatment barriers on PTSD trajectories suggest a need for early and ongoing PTSD screening postdisaster.

Communicable diseases are still major causes of deaths in developing countries. Cancer incidence, however, increased 19% between 1990 and 2000, mainly in this same developing world (Stewart and Kleihaus, 2003), and malignant neoplasms are now the second leading cause of mortality in these countries (WHO, 2003). Limitations of medical facilities and equipment mean that prevention is indispensable for cancer control (Mikheev et al., 1994). However, human resources concerning cancer prevention are limited, and encouragement of their development should be taken as a first priority. To assist in this aim, the present training course was designed by the Division of Epidemiology and Prevention, Aichi Cancer Center Research Institute, Japan, and has been annually conducted since 1999, supported by the Japan International Cooperation Agency (JICA) (Takezaki, 2001; 2002; 2003; Wakai, 2004). The course targets doctors and public health workers who are responsible for community-based cancer prevention in developing countries to promote the introduction of comprehensive procedures, focusing mainly on primary prevention but also including screening for secondary prevention of cancer.

On September 21, 2001, the AZF petrochemical factory near Toulouse (France) exploded. A cross-sectional survey of Toulouse workers took place in 2002 and then, a cohort follow-up began in 2003. The aim of this paper is to study the associations between various factors describing exposure to the disaster, and anxiety and depressive symptoms, assessed at cohort inclusion 2 years afterwards. In 2003, 3,006 people were included in the cohort. Psychological distress was measured by the GHQ28 at inclusion. Factors related to exposure to the disaster, such as personal distance from the site, physical injury, immediate psychological symptoms, and material and social effects, came from the 2002 cross-sectional survey. The links between mental health symptoms and exposure were studied in multivariate analyses by logistic regression. The prevalence of psychological distress was 47% at inclusion in the cohort. It varied according to sex and occupational class: blue-collar workers and self-employed people were most highly affected. Factors such as a history of depression, injury to a close friend or family member, sick-leaves and immediate psychological symptoms were associated with psychological distress 2 years later. These associations differed according to sex. This study shows links between the industrial disaster and psychological distress 2 years afterwards. The results about risk factors differ according to sex, and identify particularly vulnerable populations. It should guide preventive interventions in such situation.

The tumultuous catastrophic tragedies of the Oklahoma bombing in 1995 and September 11, 2001 attacks on the World Trade Center and Pentagon have caused urgency for the profession of social work to be ready to respond to unexpected crises whether directed to an individual, group, or nation. While there has always been the possibility of tragedies in the U.S. caused by nature (so-called "acts of God") or the spontaneous or planned acts of criminals or the deranged, the increased awareness of catastrophes includes, as never before, disasters that are perpetrated by terrorist acts from within or outside of the U.S. The creation of the Department of Homeland Security, in 2003, underscores the need for awareness and for preparation on the part of the nation. Based upon its skills and values, social workers have significant roles to play in the face of potential and actual disasters; yet, gerontological social workers have additional responsibilities for addressing the needs of older persons. It is the purpose of this article to provide an overview of issues to be considered by social workers, in general, and gerontological social workers, in particular, with regard to preparation for possible disasters and the consequences from such catastrophes that affect older persons.

During the geomagnetic disturbances, the geomagnetically induced current (GIC) are influenced by the geoelectric field flowing in conductive Earth. In this paper, we studied the variability of GICs, the time derivatives of the geomagnetic field (dB/dt), geomagnetic indices: Symmetric disturbance field in H (SYM-H) index, AU (eastward electrojet) and AL (westward electrojet) indices, Interplanetary parameters such as solar wind speed (v), and interplanetary magnetic field (Bz) during the geomagnetic storms on 31 March 2001, 21 October 2001, 6 November 2001, 29 October 2003, 31 October 2003 and 9 November 2004 with high solar wind speed due to a coronal mass ejection. Wavelet spectrum based approach was employed to analyze the GIC time series in a sequence of time scales of one to twenty four hours. It was observed that there are more concentration of power between the 14-24 h on 31 March 2001, 17-24 h on 21 October 2001, 1-7 h on 6 November 2001, two peaks were observed between 5-8 h and 21-24 h on 29 October 2003, 1-3 h on 31 October 2003 and 18-22 h on 9 November 2004. Bootstrap method was used to obtain regression correlations between the time derivative of the geomagnetic field (dB/dt) and the observed values of the geomagnetic induced current on 31 March 2001, 21 October 2001, 6 November 2001, 29 October 2003, 31 October 2003 and 9 November 2004 which shows a distributed cluster of correlation coefficients at around r = -0.567, -0.717, -0.477, -0.419, -0.210 and r = -0.488 respectively. We observed that high energy wavelet coefficient correlated well with bootstrap correlation, while low energy wavelet coefficient gives low bootstrap correlation. It was noticed that the geomagnetic storm has a influence on GIC and geomagnetic field derivatives (dB/dt). This might be ascribed to the coronal mass ejection with solar wind due to particle acceleration processes in the solar atmosphere.

In the present article, we outline the architecture of a computer program for simulating the process by which humans comprehend texts. The program is based on psycholinguistic theories about human memory and text comprehension processes, such as the construction-integration model (Kintsch, 1998), the latent semantic analysis theory of knowledge representation (Landauer & Dumais, 1997), and the predication algorithms (Kintsch, 2001; Lemaire & Bianco, 2003), and it is intended to help psycholinguists investigate the way humans comprehend texts.

Trends in Medicare disproportionate share (DSH) distribution in US hospitals: 1996-2003.

Implemented in 1986, Medicare's disproportionate share (DSH) adjustment is intended to recognize hospitals' additional resource investment in caring for low-income patients. This project analyzed changes in the DSH percentage between 1996 and 2003 and examined the association between selected hospital characteristics and such changes. Results obtained revealed some interesting findings. First, minimal changes in DSH percentage occurred during the period 1996-1999 with a hike in that ratio in 2000-2001. However, even with the absence of any legislative or executive changes to the DSH threshold or formula during 2002 and 2003, significant increases occurred during 2001-2003 (11 percent increase between 2001 and 2003). Such an increase may be caused by the nation's economic situation during that timeframe (i.e., more people depending on public programs for coverage).

2005-05-01

Rock weirs were constructed in a degraded section of the Cache River in southern Illinois in 2001 and 2003 to prevent channel incision and protect riparian wetlands. We sampled macroinvertebrates in two older weirs and in two sites downstream of the restored section in April 2003, October 2003, and April 2004 to evaluate differences in community structure between weir, snag, and streambed (scoured clay) habitats. Three recently constructed weirs were also sampled in April 2004. Functional composition differed among sample dates and habitats. Although collector-gatherers consistently dominated streambed habitats, functional composition on weirs and snags was more variable. Filterer and predator biomass was generally higher on weirs, and snags harbored the only shredders collected in the system (Pycnopsyche spp.). Weirs generally supported higher biomass of Ephemeroptera, Plecoptera, and Trichoptera than other habitats. For example, mean EPT biomass on weirs in 2003 (April=187 mgAFDM/m2; October=899 mgAFDM/m2) was 4 to 10-fold higher than EPT biomass in snag or streambed habitats. Late instar Pycnopsyche contributed 41% of snag biomass in April 2004, resulting in EPT biomass similar to rock weirs. Results indicate rock weirs provide suitable stable substrate for macroinvertebrates and may enhance populations of sensitive EPT taxa in degraded systems.

The attacks on the World Trade Center in 2001 resulted in hazardous environmental exposures of enormous magnitude, bringing about persistent respiratory and psychological problems among survivors. Approximately 40,000 men and women worked at Ground Zero, the former site of the World Trade Center in New York City, and at the Staten Island landfill, the main wreckage depository, in the days, weeks, and months following 9/11. First responders such as firefighters and police, construction workers, and utility and public sector workers were involved. These individuals were at high risk for injury, respiratory complications, and psychological distress from the traumatic event. This article highlights the controversy surrounding 9/11 research and reports, identifies populations at high risk for exposure, and examines the health effects. Occupational health nurses should not only be empowered to provide the best care for workers affiliated with 9/11, but also contribute to research to protect worker health in future disaster responses.

Are low wages risk factors for hypertension?

Objective: Socio-economic status (SES) is strongly correlated with hypertension. But SES has several components, including income and correlations in cross-sectional data need not imply SES is a risk factor. This study investigates whether wages—the largest category within income—are risk factors. Methods: We analysed longitudinal, nationally representative US data from four waves (1999, 2001, 2003 and 2005) of the Panel Study of Income Dynamics. The overall sample was restricted to employed persons age 25–65 years, n = 17 295. Separate subsamples were constructed of persons within two age groups (25–44 and 45–65 years) and genders. Hypertension incidence was self-reported based on physician diagnosis. Our study was prospective since data from three base years (1999, 2001, 2003) were used to predict newly diagnosed hypertension for three subsequent years (2001, 2003, 2005). In separate analyses, data from the first base year were used to predict time-to-reporting hypertension. Logistic regressions with random effects and Cox proportional hazards regressions were run. Results: Negative and strongly statistically significant correlations between wages and hypertension were found both in logistic and Cox regressions, especially for subsamples containing the younger age group (25–44 years) and women. Correlations were stronger when three health variables—obesity, subjective measures of health and number of co-morbidities—were excluded from regressions. Doubling the wage was associated with 25–30% lower chances of hypertension for persons aged 25–44 years. Conclusions: The strongest evidence for low wages being risk factors for hypertension among working people were for women and persons aged 25–44 years. PMID:22262559

Background The frequency of avian influenza A virus infections among poultry workers is not well understood. Methods A seroprevalence study of market poultry workers and persons without occupational poultry exposure was conducted during 2001 in Hanoi, Vietnam. Sera were tested for avian influenza H5 and H9 antibodies by microneutralization and Western blot assays. Results Seroprevalence of H5 and H9 antibodies was 4% and 3% in poultry workers and 1% and 3.5% in non-poultry workers, respectively. Conclusions Seroprevalence of H5 and H9 antibodies was low among Hanoi market poultry workers in 2001, but can serve as a baseline for additional studies. PMID:22928049

There is little published about the role of individual characteristics in occupational injuries. Construction workers have a high rate of injury; we assessed 11 personal characteristics in this professional sector. A case-control study was conducted on 880 male workers who had had at least one occupational injury during a 2-year period and 880 controls. A questionnaire was administered by an occupational physician. Statistical analysis was made via logistic regression method. Young age (<30 years), sleep disorders and current smoker influenced all the injuries combined. Sleep disorders and young age were common risk factors for several jobs. Physical disabilities and no sporting activity had a role in masons, and 5 years or less in present job in plumbers and electricians only. Sleep disorders influenced both the injuries with and without hospitalization; young age, current smoker, and physical disability influenced those without hospitalization only. Young age, sleep disorders, smoking, disabilities, sporting activity, and experience influenced the occupational injuries. The risk for each worker depended on his job. Occupational physicians could inform the workers of these risks and encourage them to take remedial action. Copyright 2003 Wiley-Liss, Inc.

Relationship between organizational justice and organizational safety climate: do fairness perceptions influence employee safety behaviour?

PubMed

Gyekye, Seth Ayim; Haybatollahi, Mohammad

2014-01-01

This study investigated the relationships between organizational justice, organizational safety climate, job satisfaction, safety compliance and accident frequency. Ghanaian industrial workers participated in the study (N = 320). Safety climate and justice perceptions were assessed with Hayes, Parender, Smecko, et al.'s (1998) and Blader and Tyler's (2003) scales respectively. A median split was performed to dichotomize participants into 2 categories: workers with positive and workers with negative justice perceptions. Confirmatory factors analysis confirmed the 5-factor structure of the safety scale. Regression analyses and t tests indicated that workers with positive fairness perceptions had constructive perspectives regarding workplace safety, expressed greater job satisfaction, were more compliant with safety policies and registered lower accident rates. These findings provide evidence that the perceived level of fairness in an organization is closely associated with workplace safety perception and other organizational factors which are important for safety. The implications for safety research are discussed.

To evaluate the quantity and quality of published literature conducted by pharmacy practice faculty members in US colleges and schools of pharmacy for the years 2001-2003. The Web of Science bibliographic database was used to identify publication citations for the years 2001-2003, which were then evaluated in a number of different ways. Faculty members were identified using American Association of Colleges of Pharmacy rosters for the 2000-2001, 2001-2002, and 2002-2003 academic years. Two thousand three hundred seventy-four pharmacy practice faculty members generated 1,896 publications in Web of Science searchable journals. A small number of faculty members (2.1%) were responsible for a large proportion of publications (30.6%), and only 4.9% of faculty members published 2 or more publications in these journals per year. The average impact factor for the top 200 publications was 7.6. Pharmacy practice faculty members contributed substantially to the biomedical literature and their work has had an important impact. A substantial portion of this work has come from a small subset of faculty members.

Compensating differentials, labor market segmentation, and wage inequality.

PubMed

Daw, Jonathan; Hardie, Jessica Halliday

2012-09-01

Two literatures on work and the labor market draw attention to the importance of non-pecuniary job amenities. Social psychological perspectives on work suggest that workers have preferences for a range of job amenities (e.g. Halaby, 2003). The compensating differentials hypothesis predicts that workers navigate tradeoffs among different job amenities such that wage inequality overstates inequality in utility (Smith, 1979). This paper joins these perspectives by constructing a new measure of labor market success that evaluates the degree to which workers' job amenity preferences and outcomes match. This measure of subjective success is used to predict workers' job satisfaction and to test the hypothesis that some degree of labor force inequality in wages is due to preference-based tradeoffs among all job amenities. Findings demonstrate that the new measure predicts workers' job satisfaction and provides evidence for the presence of compensating differentials in the primary and intermediate, but not secondary, labor markets.

Soler-López, Luis R.

2008-01-01

Lago Guayabal dam is located on the Rio Jacaguas in the municipality of Villalba in southern Puerto Rico, about 4 kilometers north of the town of Juana Diaz and about 5 kilometers south of Villalba (fig. 1). The dam is owned and operated by the Puerto Rico Electric Power Authority (PREPA) and was constructed in 1913 for the irrigation of croplands in the southern coastal plains of Puerto Rico. The reservoir impounds the waters of the Rio Jacaguas and those of the Rio Toa Vaca, when the Toa Vaca dam overflows or releases water. The reservoir has a drainage area of 53.8 square kilometers. The dam is a concrete gravity structure with a normal pool (at top of flashboards) elevation of 103.94 meters above mean sea level (Puerto Rico Electric Power Authority, 1988). During October 2006, the U.S. Geological Survey (USGS), Caribbean Water Science Center, in cooperation with the Puerto Rico Aqueduct and Sewer Authority (PRASA) conducted a bathymetric survey of Lago Guayabal to update the reservoir storage capacity and actualize the reservoir sedimentation rate by comparing the 2006 data with the previous 2001 bathymetric survey results. The purpose of this report is to describe and document the USGS sedimentation survey conducted at Lago Guayabal during October 2006, including the methods used to update the reservoir storage capacity, sedimentation rates, and areas of substantial sediment accumulation since December 2001. The Lago Guayabal sedimentation history up to 2001 was published by the USGS in 2003 (Soler-Lopez, 2003); therefore, this report focuses on the comparison between the 2001 and current bathymetric surveys of Lago Guayabal.

Workers are potentially exposed to asthmagens daily. Our study was conducted to estimate the prevalence of asthma among working adults in the U.S. by industry and occupation. Using data from the National Health and Nutrition Examination Survey (2001-2004), multiple logistic regression was used to investigate associations between industry and occupation and current asthma as defined by positive responses to "Has a doctor or other health professional ever told you that you have asthma?" and "Do you still have asthma?" Workers in mining (17.0%), health-related industries (12.5%), teaching (13.1%), or in health-related occupations (12.6%) had the highest prevalence of asthma. As compared to construction industry workers, workers in mining (aOR = 5.2, 95% CI: 1.1-24.2) or health-related (aOR = 2.3, 95% CI: 1.1-4.8) industries had significantly higher odds of asthma. Our study adds to the increasing evidence that miners, healthcare workers and teachers remain high-risk working populations and appropriate evaluation and control measures are needed to protect these workers. 2010 Wiley-Liss, Inc.

Fatal accidents in nighttime vs. daytime highway construction work zones.

PubMed

Arditi, David; Lee, Dong-Eun; Polat, Gul

2007-01-01

Awareness about worker safety in nighttime construction has been a major concern because it is believed that nighttime construction creates hazardous work conditions. However, only a few studies provide valuable comparative information about accident characteristics of nighttime and daytime highway construction activities. This study investigates fatal accidents that occurred in Illinois highway work zones in the period 1996-2001 in order to determine the safety differences between nighttime and daytime highway construction. The lighting and weather conditions were included into the study as control parameters to see their effects on the frequency of fatal accidents occurring in work zones. According to this study, there is evidence that nighttime construction is more hazardous than daytime construction. The inclusion of a weather parameter into the analysis has limited effect on this finding. The study justifies establishing an efficient work zone accident reporting system and taking all necessary measures to enhance safety in nighttime work zones.

To feed its rapidly growing energy demand, oil exploitation in China has never been more intensive. The most obvious characteristics of oil exploitation are progressive and regional, which can be monitored by remote sensing, such as land use and cover change, either perpetual or temporary, during oil field development such as construction of oil well, roads, transportation systems and other facilities. In this paper, the oil field located on the north edge of Taklimakan Desert, in the Tarim River watershed in northwest of China. The disturbance effects of regional oil exploitation were the main content of regional environmental managements and monitoring. Based on Enhanced Thematic Mapper Plus (ETM+) and Aster images, analyzed regional land use and landscape change from 2001 to 2003. By the comparison, it can be concluded that the ecological quality was deteriorating in these 3 years. The woodland was degrading to grass and desert. The area of woodland dropped from 9.06 km(2) in 2001 to 3.24 km(2) in 2003 with a 64.23% decrease. At the same time, the area of shrubbery lessened 18.23%. On the other hand, the whole area of desert and Saline soils inflated from 15.08 km(2) in 2001 to 25.36 km(2) in 2003. The patch number of bare land did climb dramatically, but single patch area increased. The research demonstrated that desert and Saline soils patches were activated by the human behavior and climate change. The information from the ETM+ and Aster images was proved be an effective and efficient way to be applied in regional environmental managements.

Fatalities among oil and gas extraction workers--United States, 2003-2006.

PubMed

2008-04-25

Oil and gas extraction (i.e., removing oil and natural gas from the ground) is a growing industry in the United States, employing approximately 380,000 workers in 2006. In recent years, activity in this industry has increased substantially, from an average of 800 actively drilling rigs in the United States during the 1990s to approximately 1,300 during 2003-2006. In August 2005, the U.S. Department of Labor's Bureau of Labor Statistics (BLS) asked CDC to investigate a 15% increase in fatalities among oil and gas extraction workers (from 85 fatalities in 2003 to 98 in 2004). CDC analyzed data from the BLS Census of Fatal Occupational Injuries (CFOI) for the period 2003-2006. This report describes the results of that analysis, which indicated that increases in oil and gas extraction activity were correlated with an increase in the rate of fatal occupational injuries in this industry, with an annual fatality rate of 30.5 per 100,000 workers (404 fatalities) during 2003-2006, approximately seven times the rate for all workers (4.0 per 100,000 workers). Nearly half of all fatal injuries among these workers were attributed to highway motor-vehicle crashes and workers being struck by machinery or equipment. Employers should work with existing industry groups and federal, state, and local government agencies to promote seatbelt use. In addition, researchers and public health officials should collaborate with industry groups to establish engineering and process controls that remove workers from potentially dangerous machinery while drilling and servicing oil and gas wells.

To compare demography, sexual health awareness, migration and workplace conditions of Asian female sex workers in Sydney in 1993 and 2003. A Chinese interpreter and a Thai-speaking health education officer (HEO) were used to administer a questionnaire survey to Thai- and Chinese-speaking sex workers attending sexual health clinics in 1993. A follow-up survey, which included some women contacted at work as well as clinic attenders, was administered by Thai- and Chinese-speaking HEOs in 2003. Ninety-one female sex workers were surveyed in 1993 and 165 in 2003. Median age increased (26 years vs. 33 years, p=0.000), as did numbers of Chinese- versus Thai-speakers (1993, 25.3% Chinese vs. 2003, 58.2% Chinese, p=0.000). In 2003, the women reported more years of schooling and better English skills. Fewer reported previous sex work (48.4% vs. 17.6%, p=0.000). Numbers currently or ever on a contract decreased sharply (27.5% vs. 9.1%, p=0.000) and the majority were apparently working legally. Condom use at work for vaginal (51.6% vs. 84.8%) and oral sex (39.6% vs. 66.1%) increased significantly (p=0.001). Chinese-speaking sex workers were less informed about HIV transmission and safer sex practices than were Thai sex workers. Drug and alcohol use was low. Positive changes have occurred in the conditions of Asian female sex workers surveyed over 10 years in Sydney. Maintaining current levels of health service delivery will ensure continued improvements in health and workplace conditions and address inequalities between language groups.

Thailand borders some of the world's largest methamphetamine and opioid producing countries and trafficking routes. Thailand's 'War on Drugs' campaign was launched in 2003. This study reports trends in illicit substance use in Thailand over the period 2001-2011. National Household surveys on illicit drug use were conducted in 2001, 2003, 2007, 2008 and 2011. A stratified multi-stage cluster random sampling technique was implemented for each survey. Provinces in four regions were systematically selected using a probability proportionate to the size of the targeted population. Participants were interviewed using structured questionnaires on their history of substance use. The prevalence of illicit drug use within the past drastically decreased from 4.5% in 2001 to 1.0% in 2003 (P < 0.05). Since 2003, the prevalence of illicit use within the past year varied between 1.0% and 1.3%. By 2011, it was estimated that 0.84% have used kratom (a substance derived from Mitragyna speciosa) within the past year. Around 0.20% and 0.19% reported using cannibis and yaba (metamphetamine tablet) within a year of the 2011 survey. Other types of illicit drugs were less commonly used in Thailand. There was a decrease in prevalence of illicit drug use within the past year between 2001 and 2003 in Thailand. Since 2003, the past year prelavence of illicit drug use has remained relatively stable. From 2001 to 2011, cannabis, kratom and yaba have remained the three most commonly reported types of illicit drugs used in Thailand. © 2018 Australasian Professional Society on Alcohol and other Drugs.

[Regulation requirements for the protection of workers against electromagnetic fields occurring in the work environment].

2006-01-01

In Poland, electromagnetic fields (EMF), one of potentially hazardous physical factors occurring in the work environment, are subjected to compulsory surveillance. In 2001, the Directive issued by the Minister of Labor and Social Policy substantially changed the approach towards the protection of workers against EMF. The Directive regulates the whole range of EMF frequencies and electromagnetic radiation, namely from 0 Hz to 300 GHz, which means the possibility of assessing worker's EMF exposure, determined by exposure index, along with the hygiene assessment of EMF sources, defined by protection zones. In 2003-2005, a number of amended executive and supplementary regulations were issued. However, it should be emphasized that in the process of their elaboration, striving after perfection, numerous incoherent and ambiguous provisions were adopted, which finally created difficulties in the interpretation of individual regulations. This is also linked with doubts and discussions on their practical application by services responsible for control, measurements and monitoring of working conditions under the exposure to EMF. In this work an attempt was made to clarify all issues and arrange them according to the faced problems. The authors also present proposals how to solve all these problems.

To assess the effectiveness of safety inspections in the construction industry in Piedmont in terms of exposure to risk and injuries. We conducted a retrospective analysis of the surveillance activities carried out in Piedmont between 2001 and 2005: to this purpose, we used a logical framework and we identified indicators to evaluate the process and its impact on exposure and injuries. fixed standards involving the number of safety inspections and the type of constructions under control were respected; there was always sufficient diversity among the public works under control, although local health units used different working methods. Impact on exposure and injuries: injury rates in the construction industry in Piedmont showed a decreasing trend and systematically lower values compared to national rates. Injury rates in the "roads and railways" sector showed an increasing trend owing to the great number of public works under construction. In this case, the effect of preventive measures seems less noticeable, but this mainly depends on methodological limits, such as mismatch between numerator and denominator, difficulties in estimating the number of workers actually present on the sites, underreporting of minor events. Despite the limitations of a retrospective analysis, the Piedmont safety inspection programme for the construction industry showed coherence with the objectives and had a positive impact on injury rates.

2003-01-01

Objective: To estimate the infection curve of severe acute respiratory syndrome (SARS) using the back projection method and to assess the effectiveness of interventions. Design: Statistical method. Data: The daily reported number of SARS and interventions taken by Hong Kong Special Administrative Region (HKSAR) up to 24 June 2003 are used. Method: To use a back projection technique to construct the infection curve of SARS in Hong Kong. The estimated epidemic curve is studied to identify the major events and to assess the effectiveness of interventions over the course of the epidemic. Results: The SARS infection curve in Hong Kong is constructed for the period 1 March 2003 to 24 June 2003. Some interventions seem to be effective while others apparently have little or no effect. The infections among the medical and health workers are high. Conclusions: Quarantine of the close contacts of confirmed and suspected SARS cases seems to be the most effective intervention against spread of SARS in the community. Thorough disinfection of the infected area against environmental hazards is helpful. Infections within hospitals can be reduced by better isolation measures and protective equipments. PMID:14573569

Unemployment Among Mexican Immigrant Men in the United States, 2003 – 2012

2014-01-01

Based on their socioeconomic characteristics, Mexican immigrant men should have very high un-employment. More than half do not have a high school diploma. One in four works in construction; at the height of the recent recession, 20% of construction workers were unemployed. Yet their unemployment rates are similar to those of native-born white men. After controlling for education and occupation, Mexican immigrant men have lower probabilities of unemployment than native-born white men – both before and during the recent recession. I consider explanations based on eligibility for unemployment benefits, out-migrant selection for unemployment, and employer preferences for Mexican immigrant labor. PMID:25432614

Introducing mental health and substance use screening into a community-based health service in Australia: usefulness and implications for service change.

Thomas, Anna C; Staiger, Petra K

2012-11-01

Mental health issues such as depression or anxiety and alcohol or other drug (AOD) problems often remain undiagnosed and untreated despite their prevalence in the community. This paper reports on the implementation and evaluation of an AOD and depression/anxiety screening programme within two Community Health Services (CHS) in Australia. Study 1 examined results from 5 weeks of screening (March-April 2008) using the Patient Health Questionnaire (two- and nine-item, Kroenke et al. 2001, 2003), the Conjoint Screen for Alcohol and other Drug Problems (Brown et al. 2001) and the Alcohol, Smoking and Substance Involvement Screening Test (Humeniuk & Ali 2006). Of the 55 clients screened, 33% were at risk of depression or anxiety, 22% reporting moderate-severe depression. Thirteen per cent were at risk of substance use disorders. A substantial proportion of at-risk clients were not currently accessing help for these issues from the CHS and therefore screening can facilitate identification and treatment referral. However, the majority of eligible clients were not screened, limiting screening reach. A second study evaluated the screening implementation from a process perspective via thematic analysis of focus group data from six managers and 14 intake/assessment workers (April 2008). This showed that when screening occurred, it facilitated opportunities for education and intervention with at-risk clients, although cultural mores, privacy concerns and shame/stigma could affect accuracy of screen scores at times. Importantly, the evaluation revealed that most decisions not to screen were made by workers, not by clients. Reasons for non-screening related to worker discomfort in asking sensitive questions and/or managing client distress, and a reluctance to spend long periods of time screening in time-pressured environments. The evaluation suggested that these problems could be resolved by splitting screening responsibilities, enhancing worker training and expanding follow-up screening. Findings will inform any community-based health system considering introducing screening. © 2012 Blackwell Publishing Ltd.

Legal Status and Wage Disparities for Mexican Immigrants.

2010-12-01

This paper employs a unique method of imputing the legal status of Mexican immigrants in the 1996-1999 and 2001-2003 panels of the Survey of Income and Program Participation to provide new evidence of the role of legal authorization in the U.S. on workers' wages. Using growth curve techniques, we estimate wage trajectories for four groups: documented Mexican immigrants, undocumented Mexican immigrants, U.S-born Mexican Americans, and native non-Latino whites. Our estimates reveal a 17 percent wage disparity between documented and undocumented Mexican immigrant men, and a 9 percent documented-undocumented wage disparity for Mexican immigrant women. We also find that in comparison to authorized Mexicans, undocumented Mexican immigrants have lower returns to human capital and slower wage growth.

Recent changes in estuarine benthic and suprabenthic communities resulting from the development of harbour infrastructure.

Using a Before/During/After sampling protocol, the effects of the Le Havre harbour extension, which was started at the end of 2001, on the macrobenthic and suprabenthic communities in the eastern Bay of Seine (English Channel) were examined. As the construction phase has not yet been completed, the results presented here reflect only the data collected before and during the operations (September 2000 and 2002 for benthos sampling and March 2001, September 2001, October 2002 and March 2003 for suprabenthos sampling). Although bio-sedimentary changes did occur at the mouth of the Seine river, an analysis of benthic assemblages reveals that the dredging and construction operations do not seem to have influenced assemblage structure or the spatial distribution of organisms. Comparisons of the suprabenthic assemblages at each sampling date indicate that seasonal dynamics was mainly responsible for determining species distribution. We conclude that, 1 year into the harbour management plan, the observed changes in benthic and suprabenthic assemblage abundance do not exceed the range of spatial variability that exists naturally in the Seine estuary. Despite this compensatory actions designed to protect the aquatic habitats and to preserve a sustainable and healthy ecosystem have been added to the infrastructure development plan.

2013-07-01

The purpose of this study was to examine trends in the Psychiatry Resident-In-Training Examination (PRITE®) scores at one institution from 2001 to 2010. The authors hypothesized that two factors, the 2003 implementation of the Accreditation Council for Graduate Medical Education (ACGME) duty-hour restrictions and the residency program's 2008 restructuring of its curriculum to a half-day per week of didactics, would lead to improved scores. Residents in the general psychiatry program at the University of Florida College of Medicine from 2001 to 2010 were included in this study. To examine the effect of the 2003 ACGME duty-hours change, the authors compared test results from 2001-2002 and 2003-2010. To examine the effect of the 2008 didactic restructuring, they compared test results from 2001-2007 and 2008-2010. There were 288 PRITE test scores from 2001 to 2010. The authors did not find a statistical difference between test results before and after the 2003 implementation of ACGME duty-hour restrictions or between test results before and after the 2008 restructuring of residency didactics. The hypothesis was rejected. The results of the literature review propose that examination scores are affected by other elements of residency training.

Eight aerial surveys were flown north of the Hawaiian island of Kauai during 2001 when the North Pacific Acoustic Laboratory (NPAL) source was not transmitting, and during 2002 and 2003 when it was. All surveys were performed during the period of peak residency of humpback whales (Feb-Mar). During 2002 and 2003, surveys commenced immediately upon cessation of a 24-h cycle of transmissions. Numbers and distribution of whales observed within 40 km of the NPAL source during 2001 (source off) were compared with those observed during 2002 and 2003 (source on). A total of 75 sightings was noted during 2001, as compared with 81 and 55 during 2002 and 2003, respectively. Differences in sighting rates (sightings/km) across years were not statistically significant. Assessment of distributional changes relied upon comparisons of three measures: (a) location depths; (b) distance from the NPAL source; and (c) distance offshore. None of the distributional comparisons revealed statistically significant differences across years. Several possible interpretations are examined: (a) whales have habituated to the NPAL signal; (b) insufficient statistical power exists in the present design to detect any effects; and (c) the effects are short-lived and become undetectable shortly after the cessation of transmissions.

The USGS-Great Lakes Science Center has collected dreissenid mussels annually from Lake Michigan since zebra mussels (Dreissena polymorpha) became a significant portion of the bottom-trawl catch in 1999. For this study, we investigated dreissenid distribution, body mass, and recruitment at different depths in Lake Michigan during 2001-2003. The highest densities of dreissenid biomass were observed from depths of 27 to 46 m. The biomass of quagga mussels (Dreissena bugensis) increased exponentially during 2001-2003, while that of zebra mussels did not change significantly. Body mass (standardized for a given shell length) of both species was lowest from depths of 27 to 37m, highest from 55 to 64 m, and declined linearly at deeper depths during 2001-2003. Recruitment in 2003, as characterized by the proportion of mussels < 11 mm in the catch, varied with depth and lake region. For quagga mussels, recruitment declined linearly with depth, and was highest in northern Lake Michigan. For zebra mussels, recruitment generally declined non-linearly with depth, although the pattern was different for north, mid, and southern Lake Michigan. Our analyses suggest that quagga mussels could overtake zebra mussels and become the most abundant mollusk in terms of biomass in Lake Michigan.

We present unusual negative magnetic bay-like disturbances occurred in the dayside polar geomagnetic latitudes under positive IMF Bz. The considered events were observed during the recovery phase of the storm of May 30, 2003 and the main phase of the storm of Nov 24, 2001. We call such magnetic disturbances "dayside polar substorms". It is supposed that the development of dayside polar substorms can be represented as a magnetospheric response to a significant change of the IMF Bz from negative to high positive values. The vector construction of the geomagnetic data (Scandinavian magnetometer chain IMAGE) demonstrated a clockwise vortex during the storm of Nov 24, 2001, and two opposing vortices in the event of May 30, 2003. These vortices could be regarded as a proxy of an intensification of downward and upward field-aligned currents. This assumption is based on the IZMIRAN model estimations and the simultaneous DMSP and CHAMP satellite data. According to the OVATION model and the electron images from IMAGE satellite, the Scandinavian polar stations that registered these dayside polar magnetic substorms, were mapped into the dayside auroral oval, i.e. inside the closed magnetosphere.

Prioritizing industries for occupational injury and illness prevention and research, Washington State Workers' compensation claims, 1999-2003.

Bonauto, David; Silverstein, Barbara; Adams, Darrin; Foley, Michael

2006-08-01

The objective of this study was to identify high-risk industry groups for effective allocation of occupational safety and health prevention and research resources. We used all compensable Washington state workers' compensation claims to rank North American Industry Classification System (NAICS) industry groups by a "prevention index" (PI). The PI is the average of the rank orders of each industry group's claim count and claim incidence rate. Of the 274 industry groups ranked by PI for all compensable workers' compensation claims, the following industry groups ranked the highest: NAICS 2381 Foundation, Structure, and Building Exterior Contractors, NAICS 4841 General Freight Trucking, and NAICS 2361 Residential Building Construction. Industry group PI rankings are reported for the seven most common costly occupational injury types. Use of a PI can focus prevention and research resources where they can be of most benefit.

The family Elachisinidae Ponder, 1985 includes minute marine gastropods that live predominantly in the sublittoral zone (Ponder & Keyzer 1998; Rolán & Rubio 2001; Rolán & Gofas 2003). Most elachisinids have been included in the genus Elachisina Dall, 1918 based on their shell morphology (Warén 1996; Rolán & Rubio 2001; Rolán & Gofas 2003), consequently, very little is known about the habitat and ecological niche of the species (Ponder & Keyzer 1998; Rolán & Gofas 2003). Elachisina floridana (Rehder, 1943) is the only Atlantic congener collected alive, and is known to live beneath rocks and in rocky crevices in the intertidal zone to about 1 m depth in the Bahamas and Caribbean Sea (Ponder 1985; Ponder & Keyzer 1998; Rolán & Gofas 2003; Redfern 2013). Eastern Atlantic E. canarica (Nordsieck & García-Talavera, 1979) was also collected alive from the Canary Islands, but with no information on the habitat (Rolán & Gofas 2003). The islands of the northeastern Atlantic and West Africa are the regions with the greatest Elachisina richness known, totaling nine species (Rolán & Rubio 2001; Rolán & Gofas 2003). Only E. floridana has been recognized so far to be widely distributed throughout the Western Atlantic (Rolán & Gofas 2003; Rios 2009; Redfern 2013).

Objective The aim was to compare the changes in parents' oral health-related behaviour, knowledge and attitudes in 2001-2003 and 2003-2005, during a 3.4-year-intervention in Pori and in the reference area Rauma, Finland. Materials and methods The study population consisted of parents of children who participated in the oral health promotion programme in Pori (all 5th and 6th graders who started the 2001-2002 school year in the town of Pori, n = 1691) and the parents of same-aged children in a reference town (n = 807). In 2001-2003, the promotion was targeted only to the children in Pori. In 2003-2005, the promotion was targeted also to parents, for example via local mass media. The statistical significances of the differences in parents' self-reported behaviour, knowledge and attitudes, and changes in these, were evaluated using Mann-Whitney U-tests and confidence intervals. Results In 2001-2003, the trend in changing behaviours was in favour of parents in Pori. Mothers in Pori also improved their knowledge and the attitude 'importance of brushing for health and appearance'. In 2003-2005, the trend in changing behaviours was rather similar in both towns, which may be due to diffusion of the oral health intervention to Rauma via the media. Conclusions The results suggest that health promotion targeted to children, which in previous studies has been shown to be successful in improving children's behaviours, also helped their parents in mending their habits.

(1) To investigate the association between temperature and work-related injuries and (2) to identify groups of workers at high risk of work-related injuries in hot environments in Adelaide, South Australia. Workers' compensation claims in Adelaide, South Australia for 2001-2010 were used. The relationship between temperature and daily injury claims was estimated using a generalised estimating equation model. A piecewise linear spline function was used to quantify the effect of temperature on injury claims below and above thresholds. Overall, a 1°C increase in maximum temperature between 14.2°C and 37.7°C was associated with a 0.2% increase in daily injury claims. Specifically, the incidence rate ratios (IRRs) for male workers and young workers aged ≤24 were (1.004, 95% CI 1.002 to 1.006) and (1.005, 95% CI 1.002 to 1.008), respectively. Significant associations were also found for labourers (IRR 1.005, 95% CI 1.001 to 1.010), intermediate production and transport workers (IRR 1.003, 95% CI 1.001 to 1.005) and tradespersons (IRR 1.002, 95% CI 1.001 to 1.005). Industries at risk were agriculture, forestry and fishing (IRR 1.007, 95% CI 1.001 to 1.013), construction (IRR 1.006, 95% CI 1.002 to 1.011), and electricity, gas and water (IRR 1.029, 95% CI 1.002 to 1.058). There is a significant association between injury claims and temperature in Adelaide, South Australia, for certain industries and groups. Relevant adaptation and prevention measures are required at both policy and practice levels to address occupational exposure to high temperatures.

Cartesian oval representation of freeform optics in illumination systems.

Michaelis, D; Schreiber, P; Bräuer, A

2011-03-15

The geometrical method for constructing optical surfaces for illumination purpose developed by Oliker and co-workers [Trends in Nonlinear Analysis (Springer, 2003)] is generalized in order to obtain freeform designs in arbitrary optical systems. The freeform is created by a set of primitive surface elements, which are generalized Cartesian ovals adapted to the given optical system. Those primitives are determined by Hamiltonian theory of ray optics. The potential of this approach is demonstrated by some examples, e.g., freeform lenses with collimating front elements.

Scientific literacy and discursive identity: A theoretical framework for understanding science learning

NASA Astrophysics Data System (ADS)

Brown, Bryan A.; Reveles, John M.; Kelly, Gregory J.

2005-09-01

In this paper we propose the construct of discursive identity as a way to examine student discourse. We drew from the work of Gee (2001, Review of Research in Education, 25, 99-125) and Nasir and Saxe (2003, Educational Researcher, 32(5), 14-18) to consider the multiple contexts and developmental timescales of student discursive identity development. We argue that theories of scientific literacy need to consider the sociocultural contexts of language use in order to examine fully affiliation and alienation associated with appropriation of scientific discourse. As an illustrative case, we apply discursive identity to series of short exchanges in a fifth-grade classroom of African-American students. The discussion examines potential co-construction of student identity and scientific literacy.

The research analyzed the causes for turnover rate of doctors and nurses in family health strategy teams with at least two years of implementation on March 2006 in Vale do Taquari, Rio Grande do Sul State. It is a quantitative and qualitative study identifying 31 teams in 25 towns, and the turnover rate was established by year from 1999 to 2005 by professional category. There was no turnover for doctors and nurses in 1999 and 2000. Doctor turnover was 5.9% in 2002; 32.1% in 2003; 25.8% in 2004; and 64.5% in 2005. Regarding nurses, it was 27.7% in 2001; 47% in 2002; 17.8% in 2003; 41.9% in 2004; and 22.6% in 2005. The analysis of semi-structured interviews with 7 doctors and 7 nurses appointed as main causes for turnover: poor work links, fragmented education, authoritarian way of managing, no links with the community, and poor work conditions. Thus, it is necessary to make changes regarding labor links, work conditions, and education for health workers and managers, seeking for the integrality in health practices.

This study identified activities and sources that contribute to ultrafine and other submicron particle exposure that could trigger respiratory symptoms in highway repair workers. Submicron particle monitoring was conducted for paving, milling, and pothole repair operations in a major metropolitan area where several highway repair workers were identified as symptomatic for respiratory illness following exposures at the 2001 World Trade Center disaster site. Exposure assessments were conducted for eight trades involved in road construction using a TSI P-Trak portable condensation particle counter. Direct readings near the workers' breathing zones and observations of activities and potential sources were logged on 7 days on 27 workers using four different models of pavers and two types of millers. Average worker exposure levels ranged from 2 to 3 times background during paving and from 1 to 4 times background during milling. During asphalt paving, average personal exposures to submicron particulates were 25,000-60,000, 28,000-70,000, and 23,000-37,000 particles/ cm(3) for paver operators, screed operators, and rakers, respectively. Average personal exposures during milling were 19,000-111,000, 28,000-81,000, and 19,000 particles/cm(3) for the large miller operators, miller screed operators, and raker, respectively. Personal peak exposures were measured up to 467,000 and 455,000 particles/cm(3) in paving and milling, respectively. Several sources of submicron particles were identified. These included the diesel and electric fired screed heaters; engine exhaust from diesel powered construction vehicles passing by or idling; raking, dumping, and paving of asphalt; exhaust from the hotbox heater; pavement dust or fumes from milling operations, especially when the large miller started and stopped; and secondhand cigarette smoke. To reduce the potential for health effects in workers, over 40 recommendations were made to control exposures, including improved maintenance of paver ventilation systems; diesel fume engineering controls; reduced idling; provision of cabs for the operators; and improved dust suppression systems on the milling machine.

Occupational eye injury and risk reduction: Kentucky workers' compensation claim analysis 1994-2003.

McCall, B P; Horwitz, I B; Taylor, O A

2009-06-01

Occupational eye injuries are a significant source of injury in the workplace. Little population-based research in the area has been conducted, and is necessary for developing and prioritizing effective interventions. Workers' compensation data from the state of Kentucky for the years 1994-2003 were analysed by demographics, injury nature and cause, cost, and occupational and industrial characteristics. The US Bureau of Labor Statistics' Current Population Survey was utilised to compute injury rates for demographic and occupational groups. There were 10,545 claims of ocular injury, representing 6.29 claims per 10,000 workers on average annually. A substantial drop in the claim rate was found after the state passed monetary penalties for injuries caused by employer negligence or OSHA violations. Claims by men were over three times more likely than those by women to have associated claim costs (OR 0.52; 95% CI 0.32 to 0.85; p = 0.009). The highest eye injury rates per 10,000 of 13.46 (95% CI 12.86 to 14.07) were found for the helpers/labourers occupation, and of 19.95 (95% CI 18.73 to 21.17) for the construction industry. The total cost of claim payments over the period was over $3,480,000, and average cost per claim approximated $331. Eye injuries remain a significant risk to worker health, especially among men in jobs requiring intensive manual labour. Evidence showed that increased legislative regulation led to a decline in eye injuries, which was consistent with other recent findings in the area. Additionally, targeting groups most at risk, increasing worker training, providing effective eye protection equipment, and developing workplace safety cultures may together reduce occupational eye injuries.

This document describes the progress we have made and the lessons we have learned in 2001 through 2003 under the NASA grant entitled "Solving Important Problems Faster". The long-term goal of this research is to accelerate large, irregular scientific applications which have enormous data sets and which are difficult to parallelize. To accomplish this goal, we are exploring two complementary techniques: (i) using compiler-inserted prefetching to automatically hide the I/O latency of accessing these large data sets from disk; and (ii) using thread-level data speculation to enable the optimistic parallelization of applications despite uncertainty as to whether data dependences exist between the resulting threads which would normally make them unsafe to execute in parallel. Overall, we made significant progress in 2001 through 2003, and the project has gone well.

2012-12-01

The research objective for this paper is to obtain a new extended and updated insight to the likely causes of construction accidents in Spain, in order to identify suitable mitigating actions. The paper analyzes all construction sector accidents in Spain between 2003 and 2008. Ten variables were chosen and the influence of each variable is evaluated with respect to the severity of the accident. The descriptive analysis is based on a total of 1,163,178 accidents. Results showed that the severity of accidents was related to variables including age, CNAE (National Classification of Economic Activities) code, size of company, length of service, location of accident, day of the week, days of absence, deviation, injury, and climatic zones. According to data analyzed, a large company is not always necessarily safer than a small company in the aspect of fatal accidents, experienced workers do not have the best accident fatality rates, and accidents occurring away from the usual workplace had more severe consequences. Results obtained in this paper can be used by companies in their occupational safety strategies, and in their safety training programs. Copyright © 2012 National Safety Council and Elsevier Ltd.

To reconstruct agent-specific occupational exposures for a cohort of jet engine manufacturing workers for use in an epidemiological mortality study. Potential chemical and physical exposures at eight jet engine manufacturing and overhaul/repair plants were evaluated for the period 1952 to 2001. Eleven agents were selected for detailed examination, and a job-exposure matrix was constructed. Quantitative exposure estimates were generated for metalworking fluids, nickel, cobalt, chromium, solvents, and incomplete combustion aerosol from metalworking fluids. Qualitative exposure estimates were assigned for ionizing radiation, electromagnetic fields, polychlorinated biphenyls, and lead-cadmium. All exposures showed decreasing trends over the study period. The quantitative exposure levels generated in this study were lower than early contemporaneous professional practice recommendations and were similar to or lower than published data from other industries.

2015-10-29

Although human resources for health have received increased attention by health systems decision-makers and researchers in recent years, insufficient attention has been paid to understanding the factors that influence the performance of health workers. This empirical study investigates the factors that are associated with health worker motivation over time among public sector primary health care workers in Ethiopia. The study is based on data from public sector health worker surveys collected through a convenience sample of 43 primary health care facilities in four regions (Addis Ababa, Oromia, Amhara, and Somali) at three points in time: 2003/04, 2006, and 2009. Using a Likert scale, respondents were asked to respond to statements regarding job satisfaction, pride in work, satisfaction with financial rewards, self-efficacy, satisfaction with facility resources, and self-perceived conscientiousness. Inter-reliability of each construct was assessed using Cronbach's alpha, and indices of motivational determinants and outcomes were calculated for each survey round. To explore the associations between motivational determinants and outcomes, bivariate and multivariate regression analyses were carried out based on a pooled dataset. Among the sample public sector health workers, several dimensions of health worker motivation significantly increased over the study period, including two indicators of motivational outcomes-overall job satisfaction and self-perceived conscientiousness-and two indicators of motivational determinants-pride and self-efficacy. However, two other dimensions of motivation-satisfaction with financial rewards and satisfaction with facility resources-significantly decreased. The multivariate analyses found that the constructs of pride, self-efficacy, satisfaction with financial rewards, and satisfaction with facility resources were significantly associated with the motivational outcomes, after controlling for other factors. Overall, the findings support the premise that both financial and non-financial factors are important determinants of health worker motivation in the Ethiopian context. Although the findings do not point to specific interventions that should be introduced, they do suggest possible areas that interventions should target to help improve health worker motivation.

Lung cancer mortality in North Carolina and South Carolina chrysotile asbestos textile workers.

2012-06-01

Studies of workers in two US cohorts of asbestos textile workers exposed to chrysotile (North Carolina (NC) and South Carolina (SC)) found increasing risk of lung cancer mortality with cumulative fibre exposure. However, the risk appeared to increase more steeply in SC, possibly due to differences in study methods. The authors conducted pooled analyses of the cohorts and investigated the exposure-disease relationship using uniform cohort inclusion criteria and statistical methods. Workers were included after 30 days of employment in a production job during qualifying years, and vital status ascertained through 2003 (2001 for SC). Poisson regression was used to estimate the exposure-response relationship between asbestos and lung cancer, using both exponential and linear relative rate models adjusted for age, sex, race, birth cohort and decade of follow-up. The cohort included 6136 workers, contributing 218,631 person-years of observation and 3356 deaths. Cumulative exposures at the four study facilities varied considerably. The pooled relative rate for lung cancer, comparing 100 f-yr/ml to 0 f-yr/ml, was 1.11 (95% CI 1.06 to 1.16) for the combined cohort, with different effects in the NC cohort (RR=1.10, 95% CI 1.03 to 1.16) and the SC cohort (RR = 1.67, 95% CI 1.44 to 1.93). Increased rates of lung cancer were significantly associated with cumulative fibre exposure overall and in both the Carolina asbestos-textile cohorts. Previously reported differences in exposure-response between the cohorts do not appear to be related to inclusion criteria or analytical methods.

The 2001 Mars Odyssey spacecraft was launched towards Mars on April 7, 2001. Onboard the spacecraft is the Martian radiation environment experiment (MARIE), which is designed to measure the background radiation environment due to galactic cosmic rays (GCR) and solar protons in the 20-500 MeV/n energy range. We present an approach for developing a space radiation-shielding model of the spacecraft that includes the MARIE instrument in the current mapping phase orientation. A discussion is presented describing the development and methodology used to construct the shielding model. For a given GCR model environment, using the current MARIE shielding model and the high-energy particle transport codes, dose rate values are compared with MARIE measurements during the early mapping phase in Mars orbit. The results show good agreement between the model calculations and the MARIE measurements as presented for the March 2002 dataset. c2003 COSPAR. Published by Elsevier Ltd. All rights reserved.

Cases were extracted specifically for occupational subcategories included in the Driver/Sales Workers and Truck Drivers occupational category: Driver/Sales Workers, Heavy and Tractor-Trailer Truck Drivers, and Light Truck or Delivery Services Drivers. Results In 2003–2008, the group Driver/Sales Workers and Truck Drivers had 5,568 occupational fatalities, representing 17% of all occupational fatalities in the United States. The majority of these fatalities were in the subgroup Heavy and Tractor-Trailer Truck Drivers (85%) and due to transportation incidents (80%). Older and male drivers had higher fatality rates than their counterparts. Conclusions Findings suggest a need for targeted interventions to reduce highway fatalities among heavy truck drivers. Better employment data are needed to separate the three occupational subcategories by worker characteristic and employment history for use in research and prevention efforts. PMID:24811905

In Turkey, the construction sector is responsible for the largest number of work-related fatalities among all industries. This study's objective is to determine the characteristics of the fatalities in the construction sector in Kocaeli Province. The study was carried out retrospectively by investigating the records of occupational deaths between 1990 and 2001 in the Kocaeli District of Turkey. Fatal occupational injuries in the construction sector were investigated in detail by evaluating the records. The analysis was based on data from 153 deaths. The incidence of occupational injuries was found overall to be 4.5% in Kocaeli, while the annual mortality rate was 60.4 in Kocaeli and 79.0 in Turkey per 100,000 workers over the entire time period. On the other hand, the fatality rate of occupational injuries was found to be 12.0 per 1,000 in Turkey and 6.4 per 1,000 in Kocaeli. The evaluation of the type of injuries in construction sector has revealed that in 69 of cases (45.1%) fell down from high altitude, in 22 cases (14.4%) vehicle accident, and in 22 (14.4%) electrocution were the cause of death. The leading causes of death have been found to be blunt-force trauma (37.9%) and head trauma (25.5%). Fourty one percent of those who had occupational accidents have had less than one year work experience. Only in 7.8% of deaths, the cause was determined through an autopsy.

Background Bronchiolitis obliterans, an irreversible lung disease, was first associated with inhalation of butter flavorings (diacetyl) in workers at a microwave popcorn company. Excess rates of lung-function abnormalities were related to cumulative diacetyl exposure. Because information on potential excess mortality would support development of permissible exposure limits for diacetyl, we investigated respiratory-associated mortality during 2000–2011 among current and former workers at this company who had exposure to flavorings and participated in cross-sectional surveys conducted between 2000–2003. Methods We ascertained workers' vital status through a Social Security Administration search. Causes of death were abstracted from death certificates. Because bronchiolitis obliterans is not coded in the International Classification of Disease 10th revision (ICD-10), we identified respiratory mortality decedents with ICD-10 codes J40–J44 which encompass bronchitis (J40), simple and mucopurulent chronic bronchitis (J41), unspecified chronic bronchitis (J42), emphysema (J43), and other chronic obstructive pulmonary disease (COPD) (J44). We calculated expected number of deaths and standardized mortality ratios (SMRs) with 95% confidence intervals (CI) to determine if workers exposed to diacetyl experienced greater respiratory mortality than expected. Results We identified 15 deaths among 511 workers. Based on U.S. population estimates, 17.39 deaths were expected among these workers (SMR = 0.86; CI:0.48-1.42). Causes of death were available for 14 decedents. Four deaths among production and flavor mixing workers were documented to have a multiple cause of ‘other COPD’ (J44), while 0.98 ‘other COPD’-associated deaths were expected (SMR = 4.10; CI:1.12–10.49). Three of the 4 ‘other COPD’-associated deaths occurred among former workers and workers employed before the company implemented interventions reducing diacetyl exposure in 2001. Conclusion Workers at the microwave popcorn company experienced normal rates of all-cause mortality but higher rates of COPD-associated mortality, especially workers employed before the company reduced diacetyl exposure. The demonstrated excess in COPD-associated mortality suggests continued efforts to lower flavoring exposure are prudent. PMID:23469109

The U.S. Geological Survey (USGS) sampled multiple stream sites across the St. Joseph and Galien River Basins to detect and quantify the herbicide atrazine using a field enzyme-linked immunosorbent assay (ELISA) triazine test. In May 2001, July 2001, April 2002, August 2002, August 2003 and September 2003, composite samples were collected across streams at USGS streamflow-gaging stations. Concentrations and instantaneous loading for atrazine sampled in stream water throughout the St. Joseph River and Galien River Basins in Michigan and Indiana ranged from nondetection (< 0.05 part per billion (ppb)) with an associated load less than 0.001 kilogram per day (kg/d) to 6 ppb and a maximum load of 10 kg/d. Atrazine concentrations were highest in May 2001 just after the planting season. The lowest concentration was found in April 2002 just before planting. Atrazine concentrations in streambed-sediment pore water were not spatially connected with atrazine concentrations in stream-water samples. This study showed that atrazine concentrations were elevated from May to July in the St. Joseph and Galien River Basins. At many sites, concentrations exceeded the level that has been shown to feminize frog populations (0.2 ppb). There were 8 sites where concentrations exceeded 0.2 ppb atrazine in May 2001 and July 2001.

Due to their geographical mobility and long periods of separation from intimate partners, migrant workers are at increased risk for a variety of sexually transmitted infections (STIs) including HIV/AIDS. This study sought to investigate patterns in HIV/AIDS related knowledge, attitudes and sexual behaviour in migrant workers in Croatia. In 2003, 566 male migrant workers were recruited during regular required medical examinations and surveyed at seven locations throughout the country. Each participant was asked to complete a self-administered KABP (sexual knowledge, attitudes, beliefs and practices) questionnaire. The average age of respondents was 38.2 years and the majority worked as seafarers (77.3%) and construction workers (20.5%). Only 18.5% of respondents were able to correctly answer all 13 questions assessing knowledge of HIV/AIDS. Seafarers reported higher levels of knowledge than did construction workers. The average respondent reported having had two sexual partners in the last 12 months, with slightly over half of the respondents (55.3%) reporting condom use at their last intercourse with a casual partner. One fifth of the respondents (20.3%) who reported having had intercourse with a sex worker during the last year reported not using condoms at last intercourse. The number of sexual partners was correlated with age, marital status, faith in God, and personal HIV risk assessment. Attitudes toward condom use, co-workers' HIV/AIDS concerns and the duration of migrant status (within the last two years) were shown to be significant correlates of condom use at last intercourse with a casual partner. The effect of HIV/AIDS related knowledge on analyzed behaviors did not reach statistical significance. Inadequate patterns of migrant workers' condom use, gaps in knowledge about HIV transmission and modes of protection, as well as widespread ignorance regarding available anonymous HIV testing found by this study suggest a critical need for expert intervention to avert the potential for an increase in new HIV/AIDS cases. A coordinated, systematic campaign for HIV/AIDS prevention among Croatian migrant workers should focus on increasing peer communication about HIV/AIDS, especially among younger migrant workers, and on reducing the frequency of sexual risk taking.

A 2-year study of extensive and intensive fish hatcheries was conducted to assess the general temporal occurrence of antibiotics in aquaculture. Antibiotics were detected in 15% of the water samples collected during the 2001-2002 collection period and in 31% of the samples during the 2003 collection period. Antibiotics were detected more frequently in samples from the intensive hatcheries (17 and 39%) than in samples from the extensive hatcheries (14 and 4%) during the 2001-2002 and 2003 collection periods, respectively. The maximum ormetoprim, oxytetracycline, and sulphadimethoxine concentrations were higher in samples from the intensive hatcheries (12, 10, and 36 µg L-1), respectively, than in samples from the extensive hatcheries (<0.05, 0.31, and 1.2 µg L-1), respectively. Sulphadimethoxine persisted for a longer period of time (up to 48 days) than ormetoprim (up to 28 days) and oxytetracycline (less than 20 days).

Work-related injuries among commercial janitors in Washington State, comparisons by gender.

We analyzed workers' compensation (WC) data to identify characteristics related to workers' compensation claim outcomes among janitorial service workers in Washington State. We analyzed WC data from the Washington State Department of Labor & Industries (L&I) State Fund (SF) from January 1, 2003 through December 31, 2013, for janitorial service workers employed in the National Occupational Research Agenda (NORA) Services Sector. We constructed multivariable models to identify factors associated with higher medical costs and increased time lost from work. There were 2,390 janitorial service compensable claims available for analysis. There were significant differences in injury type and other factors by gender, age, and language preference. Linguistic minority status was associated with longer time loss and higher median medical costs. Women were estimated to account for 35% of janitorial service workers but made up 55% of the compensable claims in this study. Janitorial service workers comprise a large vulnerable occupational group in the U.S. workforce. Identifying differences by injury type and potential inequitable outcomes by gender and language is important to ensuring equal treatment in the workers' compensation process. There were significant differences in injury and individual characteristics between men and women in this study. Women had twice the estimated rate of injury to men, and were more likely to require Spanish language materials. Improving communication for training and knowledge about the workers' compensation system appear to be high priorities in this population of injured janitorial service workers.

In October 2001, two envelopes containing Bacillus anthracis spores were processed at the Washington, D.C., Processing and Distribution Center of the U.S. Postal Service; inhalational anthrax developed in four workers at this facility. More than 2,000 workers were advised to complete 60 days of postexposure prophylaxis to prevent inhalational anthrax. Interventions to promote adherence were carried out to support workers, and qualitative information was collected to evaluate our interventions. A quantitative survey was administered to a convenience sample of workers to assess factors influencing adherence. No anthrax infections developed in any workers involved in the interventions or interviews. Of 245 workers, 98 (40%) reported full adherence to prophylaxis, and 45 (18%) had completely discontinued it. Experiencing adverse effects to prophylaxis, anxiety, and being <45 years old were risk factors for discontinuing prophylaxis. Interventions, especially frequent visits by public health staff, proved effective in supporting adherence. PMID:12396929

[Occupational asthma in Hungary].

PubMed

Endre, László

2015-05-10

Occupational asthma belongs to communicable diseases, which should be reported in Hungary. During a 24-year period between January 1990 and December 2013, 180 occupational asthma cases were reported in Hungary (52 cases between 1990 and 1995, 83 cases between 1996 and 2000, 40 cases between 2001 and 2006, and 5 cases between 2007 and 2013). These data are unusual, because according to the official report of the National Korányi Pulmonology Institute in Budapest, at least 14,000 new adult asthma cases were reported in every year between 2000 and 2012 in Hungary. Also, international data indicate that at least 2% of adult patients with asthma have occupational asthma and at least 50 out of 1 million employees develop occupational asthma in each year. In 2003, 631 new occupational asthma patients were reported in the United Kingdom, but only 7 cases in Hungary. Because it is unlikely that the occupational environment in Hungary is much better than anywhere else in the world, it seems that not all new occupational asthma cases are reported in Hungary. Of the 180 reported cases in Hungary, 55 were bakers or other workers in flour mills. There were 11 metal-workers, 10 health care assistants, 9 workers dealing with textiles (tailors, dressmakers, workers in textile industry) and 9 employees worked upon leather and animal fur. According to international data, the most unsafe profession is the animal keeper in scientific laboratories, but only 4 of them were reported as having occupational asthma during the studied 24 years in Hungary. Interestingly, 3 museologists with newly-diagnosed occupational asthma were reported in 2003, but not such cases occurred before or after that year. In this paper the Hungarian literature of occupational asthma is summarized, followed by a review on the classification, pathomechanism, clinical presentation, predisposing factors, diagnostics and therapeutic aspects of the disease. Epidemiological data of adult asthma in Hungary and data from international studies on the occurrence of occupational asthma are also presented. Finally, the author draws attention to the low reporting activity of occupational asthma in Hungary and discusses the possible causes why this communicable disease is rarely reported.

Occupational Hydrofluoric Acid Injury from Car and Truck Washing--Washington State, 2001-2013.

Exposure to hydrofluoric acid (HF) causes corrosive chemical burns and potentially fatal systemic toxicity. Car and truck wash cleaning products, rust removers, and aluminum brighteners often contain HF because it is efficient in breaking down roadway matter. The death of a truck wash worker from ingestion of an HF-based wash product and 48 occupational HF burn cases associated with car and truck washing in Washington State during 2001-2013 are summarized in this report. Among seven hospitalized workers, two required surgery, and all but one worker returned to the job. Among 48 injured workers, job titles were primarily auto detailer, car wash worker, truck wash worker, and truck driver. Because HF exposure can result in potentially severe health outcomes, efforts to identify less hazardous alternatives to HF-based industrial wash products are warranted.

High-Frequency Electromagnetic Impedance Measurements for Characterization, Monitoring and Verification Efforts

Non-invasive, high-resolution imaging of the shallow subsurface is needed for delineation of buried waste, detection of unexploded ordinance, verification and monitoring of containment structures, and other environmental applications. Electromagnetic (EM) measurements at frequencies between 0.1 and 100 MHz are important for such applications, because the induction number of many targets is small and the ability to determine the dielectric permittivity in addition to electrical conductivity of the subsurface is possible. Earlier workers were successful in developing systems for detecting anomalous areas, but no quantifiable information was accurately determined. For high-resolution imaging, accurate measurements are necessary so the field data canmore » be mapped into the space of the subsurface parameters. We are developing a non-invasive method for accurately mapping the electrical conductivity and dielectric permittivity of the shallow subsurface using the EM impedance approach (Frangos, 2001; Lee and Becker, 2001; Song et al., 2002, Tseng et al., 2003). Electric and magnetic sensors are being tested and calibrated on sea water and in a known area against theoretical predictions, thereby insuring that the data collected with the high-frequency impedance (HFI) system will support high-resolution, multi-dimensional imaging techniques.« less

To investigate factors influencing the practices of partial breast-feeding (PBF) and exclusive breast-feeding (EBF). A national, cross-sectional survey was conducted among married women aged 15-49 years from May to August 2003. South Korea. A total of 865 mothers answered questions regarding the feeding practices of their youngest baby, born between January 2001 and May 2003. The initiation rates of PBF and EBF were 81% and 63%, respectively. However, the median durations of PBF and EBF were very short: 12 and 8 weeks, respectively. According to stepwise logistic and Cox regression analyses, the more prenatal care women received, the more likely they were to initiate PBF and EBF but the less likely to continue EBF. Delivery by Caesarean section decreased the initiation of PBF and EBF. The mother's education level and employment status before marriage, the amount of prenatal care, delivery method and baby's status at birth affected breast-feeding initiation, whereas the amount of prenatal care influenced breast-feeding duration. To promote breast-feeding, education and campaigning on the importance of continued breast-feeding should be provided to the general public, particularly to health workers in maternity units.

The share of U.S. workers in small firms who were offered, eligible for, and covered by health insurance through their jobs has declined over the past decade. Less than half of workers in companies with fewer than 50 employees were both offered and eligible for health insurance through their jobs in 2010, down from 58 percent in 2003. In contrast, about 90 percent of workers in companies with 100 or more employees were offered and eligible for their employer's health plans in both 2003 and 2010. Workers in the smallest firms--and those with the lowest wages--continue to be less likely to get coverage from their employers and more likely to be uninsured than workers in larger firms or with higher wages. The Affordable Care Act includes new subsidies that will lower the cost of health insurance for small businesses and workers who must purchase coverage on their own.

We present the cost and cost-effectiveness of referral to an alcohol health worker (AHW) and information only control in alcohol misusing patients. The study was a pragmatic randomised controlled trial conducted from April 2001 to March 2003 in an accident and emergency department (AED) in a general hospital in London, England. A total of 599 adults identified as drinking hazardously according to the Paddington Alcohol Test were randomised to referral to an alcohol health worker who delivered a brief intervention (n = 287) or to an information only control (n = 312). Total societal costs, including health and social services costs, criminal justice costs and productivity losses, and clinical measures of alcohol consumption were measured. Levels of drinking were observably lower in those referred to an AHW at 12 months follow-up and statistically significantly lower at 6 months follow-up. Total costs were not significantly different at either follow-up. Referral to AHWs in an AED produces favourable clinical outcomes and does not generate a significant increase in cost. A decision-making approach revealed that there is at least a 65% probability that referral to an AHW is more cost-effective than the information only control in reducing alcohol consumption among AED attendees with a hazardous level of drinking.

Objective(s) To determine the effect of viral suppression on cross sectional incidence testing. Methods In 2001 and 2003, patients entering the Johns Hopkins Hospital Emergency Department (JHHED) were enrolled into an interview based, identity unlinked serosurvey. All HIV positive samples were tested by the Vironostika-less sensitive (LS) EIA and an avidity assay to determine recent HIV infection. Additionally 16 samples from 8 previously characterized elite suppressors (ES) were tested by cross sectional incidence assays. Results HIV prevalence was 12% for the 2001 survey and 11% for the 2003 survey. Of the HIV infected subjects 18% did not know they were infected. Vironostika-LS EIA determined that 6% (11/183) and 7% (17/243) of HIV+ individuals in 2001and 2003, respectively, were recently infected. Avidity testing confirmed 6 of 11 in 2001, and 5 of 17 in 2003 were newly infected, leaving 17 discrepant samples. All 17 discrepant samples were western blot positive, viral load undetectable and 7/17 had antiretroviral drugs (ARVs) in their serum. Ten individuals were virally suppressed without ARVs, appeared incident by Vironostika-LS EIA but chronic by avidity. These 10 subjects had similar testing profiles to the known 16 ES samples, as 9 of 16 were incident by Vironostika-LS EIA, and 0/16 were incident by avidity. Conclusions By removing the viral load negative individuals and by confirming the initial Vironostika-LS EIA results by avidity, the incidence estimate was lowered from 1.73 to 0.94 percent/year in 2001 and from 1.90 to 0.56 percent/year in 2003. Viral suppression affects the performance of the cross sectional incidence tests which rely on antibody titer. In additional 2% (10/426) of all HIV infected individuals who use the JHHED for medical care appear to suppress HIV to undetectable levels without ARVs. PMID:18520680

Tens of thousands of workers participated in rescue, recovery, and cleanup activities at the World Trade Center (WTC) site in lower Manhattan after the terrorist attacks on September 11, 2001 (9/11). The collapse of the WTC resulted in the release of a variety of airborne toxicants. To date, respiratory symptoms and diseases have been among the most examined health outcomes in studies of WTC disaster workers. A systematic review of the literature on respiratory health outcomes was undertaken to describe the available information on new onset of respiratory symptoms and diseases among WTC disaster workers after September 11, 2001. Independent risk factors for respiratory health outcomes included being caught in the dust and debris cloud, early arrival at the WTC site, longer duration of work, and delaying mask and respirator use. Methodological challenges in epidemiologic studies of WTC disaster workers involved study design, exposure misclassification, and limited information on potential confounders and effect modifiers. In the 10 years after 9/11, epidemiologic studies of WTC disaster workers have been essential in investigating the respiratory health consequences of WTC exposure. Longitudinal studies along with continued medical surveillance will be vital in understanding the long-term respiratory burden associated with occupational WTC exposure.

Evaluating the Impacts of Health, Social Network and Capital on Craft Efficiency and Productivity: A Case Study of Construction Workers in China.

The construction industry has been recognized, for many years, as among those having a high likelihood of accidents, injuries and occupational illnesses. Such risks of construction workers can lead to low productivity and social problems. As a result, construction workers' well-being should be highly addressed to improve construction workers' efficiency and productivity. Meanwhile, the social support from a social network and capital (SNC) of construction workers has been considered as an effective approach to promote construction workers' physical and mental health (P&M health), as well as their work efficiency and productivity. Based on a comprehensive literature review, a conceptual model, which aims to improve construction workers' efficiency and productivity from the perspective of health and SNC, was proposed. A questionnaire survey was conducted to investigate the construction workers' health, SNC and work efficiency and productivity in Nanjing, China. A structural equation model (SEM) was employed to test the three hypothetical relationships among construction workers' P&M health, SNC and work efficiency and productivity. The results indicated that the direct impacts from construction workers' P&M health on work efficiency and productivity were more significant than that from the SNC. In addition, the construction workers' social capital and the network can indirectly influence the work efficiency and productivity by affecting the construction workers' P&M health. Therefore, strategies for enhancing construction workers' efficiency and productivity were proposed. Furthermore, many useable suggestions can be drawn from the research findings from the perspective of a government. The identified indicators and relationships would contribute to the construction work efficiency and productivity assessment and health management from the perspective of the construction workers.

Antimicrobial-resistant Invasive Escherichia coli, Spain

2005-01-01

To address the public health problem of antimicrobial resistance, the European Union founded the European Antimicrobial Resistance Surveillance System. A network of 32 Spanish hospitals, serving ≈9.6 million persons, submitted antimicrobial-susceptibility data on 7,098 invasive Escherichia coli species (2001–2003). Resistance to ampicillin, cotrimoxazole, ciprofloxacin, gentamicin, and tobramycin was found at rates of 59.9%, 32.6%, 19.3%, 6.8%, and 5.3%, respectively. Resistance to multiple drugs increased from 13.8% in 2001 to 20.6% in 2003 (p <0.0001). Antimicrobial consumption data were obtained from the Spanish National Health System. In spite of decreased cephalosporin and β-lactam use, overall extended-spectrum β-lactamase production increased from 1.6% (2001) to 4.1% (2003) (p <0.0001), mainly due to the rising prevalence of cefotaximases. Resistance to ciprofloxacin significantly increased, mostly in community-onset infections, which coincided with a rise in community quinolone use. Cotrimoxazole resistance remained stable at ≈30%, even though its use was dramatically reduced. PMID:15829192

Ximelagatran (AstraZeneca).

AstraZeneca (formerly Astra) is developing ximelagatran, an orally active thrombin inhibitor and prodrug of melagatran, for the potential prevention and treatment of venous thromboembolism (VTE) in hip and knee replacement, for prevention of stroke in atrialfibrillation (AF) and for post acute coronary syndrome. As of December 1999, the compound was undergoing phase III trials for the prevention of VTE [349551]; these were ongoing in December 2001. By December 2000, ximelagatran had entered phase III trials for the prevention of stroke in atrial fibrillation [395212]. In September 2000, the company expected global NDA filing for this indication to take place in the middle of 2001 [383469]; however, in December 2000 this was revised to the second half of 2002 [395212], and in March 2001, to the second quarter of 2003 [402040], [416882], [431673]. By December 2000, a phase II trial was underway of ximelagatran as a potential treatment following myocardial infarction [395237]. In December 2001, early phase clinical trials were ongoing for post acute coronary syndrome [431673]. By December 2001, EU and US filings for VTE prevention were anticipated in the third quarter of 2002 and the second quarter of 2003, respectively [3144721, [350050], [431673]. Exanta is the trade name for both melagatran and ximelagatran. In 1998, marketing of ximelagatran in the US was to be assigned to the Astra/Merek joint marketing venture, prior to the merger [276577]. In April 1999, ABN predicted sales of 4 pounds million in 2003 [328676], [394606]. In December 2000, Lehman Brothers estimated peak sales to be $1.4 billion [394606]. At the same time, ABN-AMRO predicted peak sales of more than $1 billion [395237]. In June 2000, Deutsche Bank predicted sales of $70 million in 2002, rising to $245 million in 2003 [374500]. In September 2000, Merrill Lynch predicted sales of 125 pounds million in 2002, rising to 625 pounds million in 2004 [383742]. In February 2001, Merrill Lynch estimated that peak sales would reach $924 million in 2005 [429697].

Co-constructing cultural landscapes for disciplinary learning in and out of school: the next generation science standards and learning progressions in action

2016-12-01

The authors of this study are teacher-researchers, the first is a university researcher and former third and fourth grade teacher, while the second author is a university-based science educator. They report findings from a community-based study that Ralph, the first author, and his students conducted across two academic years (2001-2003) in order to illustrate the ways in which the next generation science standards and learning progressions can be appropriated as social-constructed practices inside and outside of school. The authors argue that what constitutes science learning in school is not a `state of grace' dictated by standards. Rather, becoming a scientist within a community of learners is a cultural phenomenon that teachers and students co-construct and as such teachers can approach the next generation science standards and learning progressions as opportunities to create intentional, disciplinary practice-based learning communities inside and outside of school.

A compilation of whole-rock and glass major-element geochemistry of Kilauea Volcano, Hawai'i, near-vent eruptive products: January 1983 through September 2001

This report presents major-element geochemical data from 652 glasses (~6,520 analyses) and 795 whole-rock aliquots from 1,002 fresh samples of olivine-tholeiitic lava collected throughout the near-continuous eruption of Kïlauea Volcano, Hawai'i, from January 1983 through September 2001. The data presented herein provide a unique temporal compilation of lava geochemistry that best reflects variations of pre-eruptive magma compositions during prolonged rift-zone eruption. This document serves as a repository for geochemical data referred to in U.S. Geological Survey Professional Paper 1676 (Heliker, Swanson, and Takahashi, eds., 2003) which includes multidisciplinary research papers pertaining to the first twenty years of Puu Oo-Kupaianaha eruption activity. Details of eruption characteristics and nomenclature are provided in the introductory chapter of that volume (Heliker and Mattox, 2003). Geochemical relations among all or portions of this data set are depicted and interpreted by Thornber (2003), Thornber and others (2003) and Thornber (2001). Trace element compositions and Nd, Sr and Pb isotopic analyses of representative samples of this select eruption suite will be provided in a separate and complimentary open file report. From 1983 to October 2001, approximately 2,500 eruption samples were collected and archived by the U.S. Geological Survey’s Hawaiian Volcano Observatory (HVO). Geochemical data for 1,002 of these samples are included here. Previous reports present bulk-lava major- element chemistry for eruption samples collected from 1983 to 1986 and from 1990 to 1994 (Neal and others, 1988 and Mangan and others, 1995, respectively). Major element glass chemistry and thermometry data for samples collected from 1983 to 1994 is reported by Helz and Hearn (1998) and whole-rock and glass chemistry for samples collected from September 1994 to October 2001 is provided by Thornber and others (2002). This report is a compilation of previously published data along with unpublished whole-rock data for the 1986–1990 eruptive interval (episode 48, see Heliker and Mattox, 2003). The geochemical data in this report is mostly limited to well-quenched samples collected at or near their respective vents. The samples include tephra and spatter, in addition to lava dipped from lava lakes, lava tubes, and surface lava flows. The details of sample collection techniques as described by Thornber and others (2002) are generally applicable for this entire sampling interval. Specifically excluded from this database are samples of distal surface flows, many of which were collected for topical studies of emplacement dynamics (for example, Cashman and others, 1999). Samples of sluggish or crystal-laden tube flows collected during eruptive pauses were also excluded, because they bear visual, petrographic and geochemical evidence for crystal accumulation during surface-flow stagnation. In addition, the pre-1992 whole-rock major element data reported here has been corrected to compensate for minor analytical discrepancies between pre- and post-1991 XRF analyses. These discrepancies resulted from a change in instrumentation at the USGS Denver analytical laboratories. This select suite of time-constrained geochemical data is suitable for constructing petrologic models of pre-eruptive magmatic processes associated with prolong rift zone eruption of Hawaiian shield volcanoes.

Although occupational accidents and work-related diseases have been of interest for a long time, due to lack of proper recording and notification systems the official numbers of occupational accidents and work-related diseases are missing for many countries. Presently, the demand for effectiveness and an interest in the economic aspects of accidents have increased prevention activities at company and country levels. Occupational accident data of selected countries and of World Health Organization regional divisions together with the global burden of disease were used in estimating global occupational accidents and fatal work-related diseases. The trend of global occupational accidents and work-related diseases is presented at region and country levels. The years 1998, 2001, and 2003 are compared in the case of occupational accidents and the years 2000 and 2002 in the case of work-related diseases. The total number of occupational accidents and fatal work-related diseases has increased, but the fatality rates per 100,000 workers have decreased. There were almost 360,000 fatal occupational accidents in 2003 and almost 2 million fatal work-related diseases in 2002. Every day more than 960,000 workers get hurt because of accidents. Each day 5,330 people die because of work-related diseases. Information on occupational accidents and work-related diseases is needed so that countries may understand better the importance of occupational health and safety at country and company level. Especially companies in developing countries are not familiar with occupational safety and health. Statistical data is essential for accident prevention; it is a starting point for the safety work.

Negative long term effects on harbour porpoises from a large scale offshore wind farm in the Baltic—evidence of slow recovery

NASA Astrophysics Data System (ADS)

Teilmann, Jonas; Carstensen, Jacob

2012-12-01

Offshore wind farms constitute a new and fast growing industry all over the world. This study investigates the long term impact on harbour porpoises, Phocoena phocoena, for more than 10 years (2001-12) from the first large scale offshore wind farm in the world, Nysted Offshore Wind Farm, in the Danish western Baltic Sea (72 × 2.3 MW turbines). The wind farm was brought into full operation in December 2003. At six stations, acoustic porpoise detectors (T-PODs) were placed inside the wind farm area and at a reference area 10 km to the east, to monitor porpoise echolocation activity as a proxy of porpoise presence. A modified statistical BACI design was applied to detect changes in porpoise presence before, during and after construction of the wind farm. The results show that the echolocation activity has significantly declined inside Nysted Offshore Wind Farm since the baseline in 2001-2 and has not fully recovered yet. The echolocation activity inside the wind farm has been gradually increasing (from 11% to 29% of the baseline level) since the construction of the wind farm, possibly due to habituation of the porpoises to the wind farm or enrichment of the environment due to reduced fishing and to artificial reef effects.

The neurotoxicity of occupational exposure to aluminium (Al)-containing welding fumes has been discussed with controversial results. The aim of the longitudinal study was to examine a group of Al welders for significant central nervous changes in comparison with a non-exposed cohort. A group of 98 Al welders (mean age 37 years) in the car-body construction industry, with a median of 6 years of occupational exposure to Al welding fumes, and an education-matched, gender-matched, age-matched control group of 50 car-production workers (mean age 36 years) at the same plant, were included in this longitudinal study. Two cross-sectional studies were done in 1999 and 2001. In the second cross-sectional study 97 welders and 50 controls could be examined. The examination programme consisted, for example, of a standardised anamnesis, focussing on occupational history, education, illnesses, medication, accidents and current alcohol consumption, a physical examination that included neurological status, and the assessment of Al concentration in plasma and urine. The neurobehavioral methods included a symptom questionnaire, modified Q16, and computerised and non-computerised tests: psychomotor performance (steadiness, line tracing, aiming, tapping), verbal intelligence (WST), simple reaction time, digit span, block design (HAWIE), symbol-digit substitution, digit span, switching attention (European neurobehavioral evaluation system, EURO-NES), and standard progressive matrices. The data were analysed by multivariate analysis of covariance (MANCOVA) for repeated measurements with covariates age, education, and carbohydrate-deficient transferrin in plasma (CDT). RESULTS. The median Al urine concentration (mean preshift/postshift) was 52.4 microg/g creatinine (2001) and 57.6 microg/g creatinine (1999). Median respirable air dust was 0.67 mg/m(3) (2001) and 0.47 mg/m(3) (1999). Welders and controls did not report significantly more symptoms in the modified Q16. Furthermore, no significant differences in psychomotor performance and other neurobehavioral tasks, except for reaction time, were seen between welders and non-welders. Regression analyses reveal a significant relationship between reaction time and Al excretion in urine that was confounded by other factors. At present the outcome for reaction time has to be interpreted as a single result. However, as the modified Q16 questionnaire and the rest of the psychomotor performance showed no significant changes, the next cross-sectional study, in 2003, will provide further information on which a final conclusion can be based.

Speech recognition index of workers with tinnitus exposed to environmental or occupational noise: a comparative study

PubMed Central

2012-01-01

Introduction Tinnitus is considered the third worst symptom affecting humans. The aim of this article is to assess complaints by workers with tinnitus exposed to environmental and occupational noise. Methodology 495 workers went through an epidemiological survey at the Audiology Department of the Center for Studies on Workers’ Health and Human Ecology, from 2003 to 2007. The workers underwent tonal and vocal audiometry, preceded by a clinical and occupational history questionnaire. Two-factor ANOVA and Tukey were the statistical tests used. All the analysis set statistical significance at α=5%. Findings There was a higher prevalence of occupational tinnitus (73.7%), a predominance of female domestic workers (65.4%) in cases of environmental exposure, and predominance of male construction workers (71.5%) for occupational exposure. There was a significant difference in workers with hearing loss, who showed a mean speech recognition index (SRI) of 85%, as compared to healthy workers with a mean SRI greater than 93.5%. Signs and symptoms, speech perception, and interference in sound localization with the type of noise exposure (environmental versus occupational) comparisons found no significant differences. Conclusion Studied group’s high prevalence of tinnitus, major difficulties in speech recognition with hearing loss and the presence of individuals with normal hearing with both types of exposure justify the importance of measures in health promotion, prevention, and hearing surveillance. The findings highlight the importance of valuing the patients’ own perception as the first indication of tinnitus and hearing loss in order to help develop appropriate public policies within the Unified National Health System (SUS).

Optical traps use tightly focused laser light to manipulate microscopic particles and have applications in nanofabrication, characterizing DNA, and in vitro fertilization [1]. We will describe the design, construction, and characterization of an optical trap that is capable of trapping and imaging 3 μm polystyrene spheres using a 12 mW HeNe laser. The design was based on previous work [2,3] describing how to build affordable optical traps. We will discuss trapping forces and their calibration. [4pt] [1] D.G.

Physical and vegetative characteristics of a relocated stream reach, constructed wetland, and riparian buffer, Upper Saucon Township, Lehigh County, Pennsylvania, 2000-04

Chaplin, Jeffrey J.; White, Kirk E.; Loper, Connie A.

2006-01-01

The U.S. Geological Survey, in cooperation with the Pennsylvania Department of Transportation, Engineering District 5-0, investigated physical and vegetative changes within a relocated stream reach, constructed wetland, and riparian buffer from September 2000 to October 2004. This report presents an evaluation of data collected using methods from multiple sources that have been adapted into a consistent approach. This approach is intended to satisfy a need for consistent collection of different types of data with the goal of transferring technology and findings to similar projects. Survey data indicate that adjustment of the upstream part of the relocated stream reach slowed over the monitoring period, but the downstream channel remains unstable as evidenced by excessive deposition. Upstream migration of a nick point has slowed or stopped altogether as of the 2003 assessment when this feature came in contact with the upstream-most part of the channel that is lined with riprap. Documented streambed erosion in the upstream cross sections, along with deposition downstream, has resulted in an overall decrease in slope of the stream channel over the monitoring period. Most streambed erosion took place prior to the 2002 assessment when annual mean streamflows were less than those in the final 2 years of monitoring. An abundance of fine sediment dominates the substrate of the relocated channel. Annual fluctuations of large particles within each cross section demonstrates the capacity of the relocated channel to transport the entire range of sediment. The substrate within the 0.28-acre constructed wetland (a mixture of soil from an off-site naturally occurring wetland and woodchips) supported a hydrophytic-vegetation community throughout the investigation. Eleocharis obtusa (spike rush), an obligate-wetland herb, was the most prevalent species, having a maximum areal cover of 90 percent in fall 2001 and a minimum of 23 percent in fall 2004. Drought-like conditions in water year 2002 (cumulative precipitation was 28.11 inches) allowed species like Panicum dichotomiflorum (witch grass), Salix sp. (willow), Leersia oryzoides (rice cutgrass), and Echinocloa crusgalli (barnyard grass) to become established by fall 2002. Above-average precipitation in water years 2003 and 2004 (58.55 and 53.17 inches, respectively) coincided with increased areal cover by E. obtusa in fall 2003 (56 percent) and decreased areal cover in fall 2004 (23 percent). Pond-like conditions that probably persisted throughout the 2004 growing season favored aquatic species like Alisma subcordatum (water plantain) to the detriment of many emergent species, including E. obtusa. Despite the pond-like conditions, L. oryzoides, an obligate-wetland grass, increased in areal cover (from 12 to 34 percent) between the 2003 and 2004 growing seasons because it was established in the higher elevations and the peripheral areas of the constructed wetland that were less prone to persistent inundation. Canopy development by trees and shrubs in the riparian buffer was initially (fall 2000) poor (39.7 percent), resulting in more available sunlight for the herbaceous understory than in any other growing season. As a result, areal cover of herbaceous species and trees and shrubs less than 1-meter tall was 108 percent in fall 2000 with Lolium perenne (perennial rye), Polygonum persicaria (lady's thumb), and Setaria faberi (foxtail) collectively contributing nearly half the cover (59.2 percent). Because of increases in canopy cover by trees and shrubs (39.7 percent in fall 2000 to 127 percent in fall 2004), herbaceous cover decreased to 76 percent by the fall of 2001 and varied between 72 and 77 percent for the rest of the study period. Tree density in the riparian buffer ranged from 3,078 and 4,130 plants per acre (fall 2000 and 2003, respectively) over the study period but essentially remained constant after fall 2001; computations reported each fall between fall 2001 and fall 2004 are within 10 percent of one another. When the study ended in fall 2004, Acer negundo (box elder) and Fraxinus pennsylvanica (green ash) were the most populous tree species (1,526 and 1,084 plants per acre, respectively) followed by Quercus bicolor (swamp white oak; 720 plants per acre). A. negundo, F. pennsylvanica, and Q. bicolor also contributed the greatest areal cover in fall 2004 (31.2, 24.0, and 18.5 percent,respectively).

A total of 1,142 grounds maintenance workers (GMWs) were fatally injured at work during 2003--2008, an average of 190 each year. GMWs accounted for 3.4% of all occupational fatalities, and 31% of those GMWs were Hispanic or Latino. Approximately 83% of the Hispanic or Latino GMWs who died were born outside the United States. In 2008, approximately 1.52 million persons were employed as GMWs, constituting 1.0% of the U.S. workforce. During 2003--2007, an average of 13.3 per 100,000 employed GMWs died each year, compared with an overall rate of 4.0 fatalities per 100,000 U.S. workers. The rate of on-the-job fatal injuries among GMWs has remained elevated relative to other workers for >20 years. This report characterizes events leading to GMW fatalities and differences in fatality characteristics across demographic groups among GMWs, based on an evaluation of 2003--2008 data from the U.S. Department of Labor's Bureau of Labor Statistics (BLS) Census of Fatal Occupational Injuries (CFOI) program. The report also identifies workplace interventions that might reduce the incidence of fatal injuries. Major events leading to GMW occupational fatalities included transportation incidents (31%), contact with objects and equipment (25%), falls (23%), and traumatic acute exposures to harmful substances or environments (e.g., electrocution and drowning) (16%). To reduce the incidence of such fatalities, employers, trade and worker associations, and policy makers should focus on effective, targeted workplace safety interventions such as frequent hazard identification and training for specific hazards. Diversity among the populations of workers requires use of culture- and language-appropriate training techniques as part of comprehensive injury and illness prevention programs.

Role of water-soluble polysaccharides in bacterial cellulose production.

Acetobacter xylinum BPR2001 produces water-insoluble bacterial cellulose (BC) and a water-soluble polysaccharide called acetan in corn steep liquor-fructose medium. Acetobacter xylinum EP1, which is incapable of acetan production was derived by disrupting the aceA gene of BPR2001. The BC production by EP1 (2.88 g/L) was lower than that by BPR2001 (4.6 g/L) in baffled-flask culture. When purified acetan or agar was added to the medium from the start of cultivation, the BC production by EP1 was enhanced and the final BC yield of EP1 was almost the same as that of BPR2001. A similar improvement of BC production by EP1 by the addition of agar was also confirmed by cultivation in a 50-L airlift reactor. From these results, the role of acetan in BC production is associated with the increase in the viscosity of the culture medium which may hinder coagulation of BC and cells in the culture, thereby accelerating the growth of BPR2001 and BC production by BPR2001.

Objectives. We sought to determine whether US physicians’ practice patterns in treating tobacco use at ambulatory visits improved over the past decade with the appearance of national clinical practice guidelines, new smoking cessation medications, and public reporting of physician performance in counseling smokers. Methods. We compared data from the National Ambulatory Medical Care Survey, an annual survey of a random sample of office visits to US physicians, between 1994–1996 and 2001–2003. Results. Physicians identified patients’ smoking status at 68% of visits in 2001–2003 versus 65% in 1994–1996 (adjusted odds ratio [AOR]=1.16; 95% confidence interval [CI]=1.04, 1.30). Physicians counseled about smoking at 20% of smokers’ visits in 2001–2003 versus 22% in 1994–1996 (AOR=0.84; 95% CI=0.71, 0.99). In both time periods, smoking cessation medication use was low (<2% of smokers’ visits) and visits with counseling for smoking were longer than those without such counseling (P<.005). Conclusions. In the past decade, there has been a small increase in physicians’ rates of patients’ smoking status identification and a small decrease in rates of counseling smokers. This lack of progress may reflect barriers in the US health care environment, including limited physician time to provide counseling. PMID:17761570

Survival Estimates for the Passage of Spring-Migrating Juvenile Salmonids through Snake and Columbia River Dams and Reservoirs, 2003-2004 Annual Report.

For juvenile chinook salmon Oncorhynchus tshawytscha, sockeye salmon O. nerka, and steelhead O. mykiss that migrate through reservoirs, hydroelectric projects, and free-flowing sections of the Snake and Columbia Rivers, survival estimates are essential to develop effective strategies for recovering depressed stocks. Many management strategies were based on estimates of system survival (Raymond 1979; Sims and Ossiander 1981) derived in a river system considerably different from today's (Williams and Matthews 1995; Williams et al. 2001). Knowledge of the magnitude, locations, and causes of smolt mortality under present passage conditions, and under conditions projected for the future, are necessary to develop strategiesmore » that will optimize smolt survival during migration. From 1993 through 2002, the National Marine Fisheries Service (NMFS) and the University of Washington (UW) demonstrated the feasibility of using three statistical models to estimate survival of PIT-tagged (Prentice et al. 1990a) juvenile salmonids passing through Snake River dams and reservoirs (Iwamoto et al. 1994; Muir et al. 1995, 1996, 2001a, 2003; Smith et al. 1998, 2000a,b; Hockersmith et al. 1999; Zabel et al. 2001, 2002). Evaluation of assumptions for these models indicated that all were generally satisfied, and accurate and precise survival estimates were obtained. In 2003, NMFS and UW completed the eleventh year of the study. Flow levels during the early portion of the 2003 spring migration were similar to 2002, and only slightly higher than in the drought conditions during 2001. However, flow levels were much greater during the later part of the migration in 2003. Spill levels were similar to 2002, much higher than in 2001. Research objectives were to: (1) estimate reach survival and travel time in the Snake and Columbia Rivers throughout the yearling chinook salmon and steelhead migrations; (2) evaluate relationships between survival estimates and migration conditions; and (3) evaluate the performance of the survival-estimation models under prevailing operational and environmental conditions. Additionally, as adult return information becomes available, as part of this study we will evaluate relationships between juvenile survival and subsequent adult returns for fish with different juvenile migration histories.« less

To assess work-related exposure to tobacco smoke in Finnish restaurants, a series of nationwide questionnaire surveys were conducted among restaurant workers and the levels of indoor air nicotine concentrations were measured in restaurants. The survey aimed to evaluate the impact of the smoke-free legislation in general and in particular after the total smoking ban launched in 2007. In 2003-2010, four national questionnaire surveys were conducted among restaurant workers and the concentration of nicotine in indoor air was measured in different types of restaurants, bars and nightclubs. Between 2003 and 2010, the proportion of restaurant workers reporting occupational exposure to tobacco smoke dropped from 59% to 11%. Among pub workers, the decrease was from 97% to 18% and in workers of dining restaurants from 49% to 10%, respectively. The median concentration of nicotine in indoor air of all restaurants decreased from 11.7 μg/m(3) to 0.1 μg/m(3). The most significant decrease was detected in pubs where the decrease was from 16.1 μg/m(3) to 0.1 μg/m(3). Among all restaurant workers, in 2003-2010 the prevalence of daily smokers was reduced from 39% to 31% in men and from 35% to 25% in women. Total prohibition of smoking but not partial restriction in restaurants was effective in reducing work-related exposure to tobacco smoke. Strict tobacco legislation may partly be associated with the significant decrease of daily smoking prevalence among restaurant workers.

Tuberculosis (TB) control in a low socio-economic society is an important program for urban area of industrialized countries. Some construction workers live in Hanba, a kind of dormitory housings that have crowded living conditions, and possibly give rise to Mycobacterium tuberculosis transmission. The pulmonary tuberculosis detection rate by chest X-ray screening in Hanba is higher than the general population, and therefore TB incidence among Hanba construction worker is also estimated to be as high as that of homeless. To analyze the ratio of the TB patients from Hanba in Chiba City from 1993 through 2006, and analyze the treatment outcome and speculate the factors affecting them, especially the effects of the inpatients DOTS (Directly Observed Treatment Short-course) policy introduction after 2001. TB registration records in the Public Health Center, Chiba City, Japan, were retrospectively analyzed. Pulmonary TB patients from Hanba were 121 (male: 121, female: 0), representing 3.8% of the total 3179 TB patients from 1993 through 2006. Restricting to male patients aged 40-59 years-old, TB patients from Hanba were 78, representing 10.7% of 729 male TB patients of the same age groups. All of TB patients from Hanba developed pulmonary TB (PTB) and treatment outcome of chemotherapy was cured or completed: 69 (57%), defaulted or failed: 43 (36%), and died 9 (7%) respectively. When compared with PTB in Chiba and Japan, defaulted or failed was higher. In the multi-variated analysis, extensive lesions more than one lung (Adjusted odds ratio [AOR]: 0.13, 95% confidence interval [CI]: 0.04-0.37, P < 0.001) and smear-positive (AOR: 0.17, 95% CI: 0.04-0.65, P = 0.009) were negative factor for cured and completed. However, hospitalization during initial period of treatment was positive factor (AOR: 7.92, 95% CI: 1.73-36.2, P = 0.008). After inpatients DOTS introduction, the rate of cured or completed increased from 50% to 67%, and the rate of failed or defaulted decreased from 46% to 22% (P < 0.05). TB patients from Hanba, a kind of dormitory housings for construction workers, occupied 3.8% of total TB patients in Chiba City. Higher rate of defaulted or failed cases leads to poor treatment outcome in TB patients of Hanba construction workers who were possibly associated with an elevated risk of urban tuberculosis. DOTS might improve adherence to treatment and result in a decrease of failed or defaulted cases.

Fatal injuries in offshore oil and gas operations - United States, 2003-2010.

PubMed

2013-04-26

During 2003-2010, the U.S. oil and gas extraction industry (onshore and offshore, combined) had a collective fatality rate seven times higher than for all U.S. workers (27.1 versus 3.8 deaths per 100,000 workers). The 11 lives lost in the 2010 Deepwater Horizon explosion provide a reminder of the hazards involved in offshore drilling. To identify risk factors to offshore oil and gas extraction workers, CDC analyzed data from the Bureau of Labor Statistics (BLS) Census of Fatal Occupational Injuries (CFOI), a comprehensive database of fatal work injuries, for the period 2003-2010. This report describes the results of that analysis, which found that 128 fatalities in activities related to offshore oil and gas operations occurred during this period. Transportation events were the leading cause (65 [51%]); the majority of these involved aircraft (49 [75%]). Nearly one fourth (31 [24%]) of the fatalities occurred among workers whose occupations were classified as "transportation and material moving." To reduce fatalities in offshore oil and gas operations, employers should ensure that the most stringent applicable transportation safety guidelines are followed.

Social audits of health services in three South African provinces (Limpopo 2001, Gauteng 2003 and Eastern Cape 2001) demonstrated a fusion of participatory research, qualitative data collection, epidemiological surveys and analysis, and socialising of evidence for action. The social audit in each province involved the community in covering eight principles of service delivery. In the particular case of Gauteng province, householders answered a questionnaire on public perceptions of government health services. In each sentinel community, the results were returned for discussion in focus groups, made up of a sample that had answered the household questionnaire. Institutional reviews of health facilities and interviews with health workers in those facilities gave the government side of the story. Five actions came from the community-based focus groups, all accepted by the provincial government. Firstly, redesigned communication strategies will aim to reach those with lower levels of education. The second set of actions involves rebuilding the culture of care. Thirdly, the public knowledge of ways to complain was closely related to levels of public satisfaction. Leadership in the health services turned out to be a fourth area for development. And finally, related to this, is the longer-term challenge of establishing and reinforcing community consultation mechanisms.

Effect of UK policy on medical migration: a time series analysis of physician registration data

PubMed Central

2012-01-01

Background Economically developed countries have recruited large numbers of overseas health workers to fill domestic shortages. Recognition of the negative impact this can have on health care in developing countries led the United Kingdom Department of Health to issue a Code of Practice for National Health Service (NHS) employers in 1999 providing ethical guidance on international recruitment. Case reports suggest this guidance had limited influence in the context of other NHS policy priorities. Methods The temporal association between trends in new professional registrations from doctors qualifying overseas and relevant United Kingdom government policy is reported. Government policy documents were identified by a literature review; further information was obtained, when appropriate, through requests made under the Freedom of Information Act. Data on new professional registration of doctors were obtained from the General Medical Council (GMC). Results New United Kingdom professional registrations by doctors trained in Africa and south Asia more than doubled from 3105 in 2001 to 7343 in 2003, as NHS Trusts sought to achieve recruitment targets specified in the 2000 NHS Plan; this occurred despite ethical guidance to avoid active recruitment of doctors from resource-poor countries. Registration of such doctors declined subsequently, but in response to other government policy initiatives. A fall in registration of South African-trained doctors from 3206 in 2003 to 4 in 2004 followed a Memorandum of Understanding with South Africa signed in 2003. Registrations from India and Pakistan fell from a peak of 4626 in 2004 to 1169 in 2007 following changes in United Kingdom immigration law in 2005 and 2006. Since 2007, registration of new doctors trained outside the European Economic Area has remained relatively stable, but in 2010 the United Kingdom still registered 722 new doctors trained in Africa and 1207 trained in India and Pakistan. Conclusions Ethical guidance was ineffective in preventing mass registration by doctors trained in resource-poor countries between 2001 and 2004 because of competing NHS policy priorities. Changes in United Kingdom immigration laws and bilateral agreements have subsequently reduced new registrations, but about 4000 new doctors a year continue to register who trained in Africa, Asia and less economically developed European countries.

We performed a retrospective cohort study in South Korea to clarify the role of occupational exposure, especially to welding, in the etiology of Parkinson's disease (PD). We constructed a database of subjects classified into an exposure group (blue-collar workers) and a non-exposure group (white-collar workers) in two shipbuilding companies. Jobs of blue-collar workers were categorized into the first group of welding, the second group of fitting, grinding and finishing, cutting, and the other group. To determine new cases of PD during the follow-up period (1992-2003), we used the physician billing claims database of the National Health Insurance Corporation. For the detected PD patients in the physician billing claims database, a neurologist in our research team confirmed the appropriateness of each diagnosis by reviewing medical charts. Based on the review, we confirmed the numbers of new cases of PD and calculated the relative risk (RR) and the 95% confidence intervals (CI) by Cox regression analysis. In a backward selection procedure, 'age' was a significant independent variable but exposure was not. Furthermore, the RR in welders (high exposure group) was also insignificant and less than that in others (very low exposure group). This longitudinal study of shipbuilding workers supports our previous case-control studies suggesting that exposure to manganese does not increase the risk of PD.

Background The terrorist attacks on the World Trade Center on September 11, 2001, exposed thousands of Fire Department of New York City (FDNY) rescue workers to dust, leading to substantial declines in lung function in the first year. We sought to determine the longer-term effects of exposure. Methods Using linear mixed models, we analyzed the forced expiratory volume in 1 second (FEV1) of both active and retired FDNY rescue workers on the basis of spirometry routinely performed at intervals of 12 to 18 months from March 12, 2000, to September 11, 2008. Results Of the 13,954 FDNY workers who were present at the World Trade Center between September 11, 2001, and September 24, 2001, a total of 12,781 (91.6%) participated in this study, contributing 61,746 quality-screened spirometric measurements. The median follow-up was 6.1 years for firefighters and 6.4 years for emergency-medical-services (EMS) workers. In the first year, the mean FEV1 decreased significantly for all workers, more for firefighters who had never smoked (a reduction of 439 ml; 95% confidence interval [CI], 408 to 471) than for EMS workers who had never smoked (a reduction of 267 ml; 95% CI, 263 to 271) (P<0.001 for both comparisons). There was little or no recovery in FEV1 during the subsequent 6 years, with a mean annualized reduction in FEV1 of 25 ml per year for firefighters and 40 ml per year for EMS workers. The proportion of workers who had never smoked and who had an FEV1 below the lower limit of the normal range increased during the first year, from 3% to 18% for firefighters and from 12% to 22% for EMS workers, stabilizing at about 13% for firefighters and 22% for EMS workers during the subsequent 6 years. Conclusions Exposure to World Trade Center dust led to large declines in FEV1 for FDNY rescue workers during the first year. Overall, these declines were persistent, without recovery over the next 6 years, leaving a substantial proportion of workers with abnormal lung function. PMID:20375403

Aeroallergens, allergic rhinitis, and sedating antihistamines: risk factors for traumatic occupational injury and economic impact.

PubMed

Hanrahan, L P; Paramore, L C

2003-10-01

The U.S. workplace injury burden is significant. Our objective was to assess the particular impact of aeroallergen, allergic rhinitis, and antihistamine exposures and side effects on the risk of traumatic work-related injuries, and the associated economic impact. This is an observational case-control study with 1,223 acute traumatic injury cases that are compared to 1,202 chronic back injury controls. Structured telephone interviews were conducted in 1998 and 1999 on Workers' Compensation applicants injured in 1997. Antihistamine use and pollen levels were measured 2 weeks prior to the injury date. Sedating antihistamine exposures elevated acute injury risk (main effect OR: 2.93). A significant increase in traumatic injury risk was observed for combined sedating antihistamine and high pollen exposures among subjects with physician and self-diagnosed allergic rhinitis (OR: 2.41). Direct medical costs associated with this increased risk were estimated at $143 million in 2001. Workers with physician-diagnosed allergic rhinitis have as high a reliance on sedating antihistamines as do self-diagnosed and self-medicating nasal allergy sufferers. High pollen exposures along with sedating antihistamine use may confer significant additional injury risks among allergic rhinitis sufferers. Medical management "best practices" of diagnosed allergic rhinitis should include avoidance of sedating antihistamines to minimize acute, traumatic injury risks. Copyright 2003 Wiley-Liss, Inc.

With the spread of the concept of sustainable development, people have gained awareness about the problem of massive illegal dumping of construction waste. In this research, a questionnaire survey was carried out in the USA and China. The results indicated the following. (1) Workers in both the countries had positive minimisation attitudes, and the attitude of Chinese construction workers was not significantly different from that of American construction workers. Furthermore, their average values were 3.9 and 4.07, respectively. (2) Business owners had a poor understanding of the obligations that should be fulfilled by contractors and construction workers, which greatly reduced (a) construction workers' and contractors' motivation to implement waste minimisation management and (b) the benefit-driven effect. (3) In terms of perceived behavioural control, Chinese construction workers had poorer minimisation technologies and knowledge than American construction workers, and it was very difficult for them to implement construction waste minimisation. The research conclusions and relevant suggestions may be used to improve the construction waste minimisation behaviour and awareness of Chinese people and promote China's construction waste minimisation management.

Given the large number of workers in the construction industry, it is important to derive accurate and valid estimates of cancer risk, and in particular lung cancer risk. In most previous studies, risks among construction workers were compared with general populations including blue and white collar workers. The main objectives of this study were to assess whether construction workers experience excess lung cancer risk, and whether exposure to selected construction industry exposures carries excess risks. We wished to address these objectives within the sub-population of blue collar workers. Two case-control studies were conducted in Montreal. Combined, they included 1593 lung cancer cases and 1427 controls, of whom 1304 cases and 1081 controls had been blue collar workers. Detailed lifetime job histories were obtained and translated by experts into histories of exposure to chemical agents. The two key analyses were to estimate odds ratio (OR) estimates of lung cancer risk: a) for all blue-collar construction workers compared with other blue-collar workers, and b) for construction workers exposed to each of 20 exposure agents found in the construction industry compared with construction workers unexposed to those agents. All analyses were conducted using unconditional logistic regression adjusted for socio-demographic factors and smoking history. The OR for all construction workers combined was 1.11 (95 % CI: 0.90-1.38), based on 381 blue collar construction workers. Analyses of specific exposures were hampered by small numbers and imprecise estimates. While none of 20 occupational agents examined was significantly associated with lung cancer, the following agents manifested non-significantly elevated ORs: asbestos, silica, Portland cement, soil dust, calcium oxide and calcium sulfate. Compared with other blue collar workers, there was only a slight increased risk of lung cancer for subjects who ever held an occupation in the construction industry. The analyses of agents within the construction industry produced imprecise estimates of risk, but nevertheless pointed to some plausible associations. Excess risks for asbestos and silica were in line with previous knowledge. The possible excess risks with the other inorganic dusts require further corroboration.

Background: On September 11, 2001, the World Trade Center (WTC) collapse caused massive air pollution, producing variable amounts of lung function reduction in the New York City Fire Department (FDNY) rescue workforce. α1-Antitrypsin (AAT) deficiency is a risk factor for obstructive airway disease. Methods: This prospective, longitudinal cohort study of the first 4 years post-September 11, 2001, investigated the influence of AAT deficiency on adjusted longitudinal spirometric change (FEV1) in 90 FDNY rescue workers with WTC exposure. Workers with protease inhibitor (Pi) Z heterozygosity were considered moderately AAT deficient. PiS homozygosity or PiS heterozygosity without concomitant PiZ heterozygosity was considered mild deficiency, and PiM homozygosity was considered normal. Alternately, workers had low AAT levels if serum AAT was ≤ 20 μmol/L. Results: In addition to normal aging-related decline (37 mL/y), significant FEV1 decline accelerations developed with increasing AAT deficiency severity (110 mL/y for moderate and 32 mL/y for mild) or with low AAT serum levels (49 mL/y). Spirometric rates pre-September 11, 2001, did not show accelerations with AAT deficiency. Among workers with low AAT levels, cough persisted in a significant number of participants at 4 years post-September 11, 2001. Conclusions: FDNY rescue workers with AAT deficiency had significant spirometric decline accelerations and persistent airway symptoms during the first 4 years after WTC exposure, representing a novel gene-by-environment interaction. Clinically meaningful decline acceleration occurred even with the mild serum AAT level reductions associated with PiS heterozygosity (without concomitant PiZ heterozygosity). PMID:20634282

The aim of this study was to examine changes in working hours, shift work, psychological and physical job demands, job control and job insecurity in Taiwanese employees by gender and age during the period of 2001 to 2010. The study subjects were 36,750 men and 27,549 women, aged 25-64, from 4 rounds of cross-sectional surveys of representative employees. Psychosocial work conditions were assessed by a validated questionnaire. Regression analyses with adjustment of education and employment grade showed that from 2001 to 2010, the proportions of workers with long working hours (>48 hours/week) (OR=1.4 in men and 1.5 in women) and workers with short working hours (<40 hours/week) (OR=1.3 in both genders) both increased over time, indicating an increasing polarization in the distribution of working hours. Furthermore, the proportions of nonstandard work shifts (OR=1.7 in men and 2.1 in women) and work with high physical demands (OR=1.5 for both gender) increased. There were signs of decreasing levels of job control from 2001 to 2007, which seemed to be more apparent in younger workers than in older workers. However, a slight recovery in decision latitude and opportunity for learning was noticed in later years. The trend in job insecurity was not linear, with the highest prevalence found in 2004. Our findings suggested that certain aspects of psychosocial work environment had deteriorated in Taiwan. There is a need to raise public awareness about the changing patterns of psychosocial health risks at work as well as their causes and their potential impacts on worker well-being.

Genetic analyses were performed on 228 influenza A(H1) viruses derived from clinical subjects participating in an experimental vaccine trial conducted in 20 countries on four continents between 2001 and 2003. HA1 phylogenetic analysis of these viruses showed multiple clades circulated around the world with regional prevalence patterns. Sixty-five of the A(H1) viruses were identified as A(H1N2), 40 of which were isolated from South Africa. The A(H1) sequences of these viruses cluster with published H1N2 viruses phylogenetically and share with them diagnostic signature V169A and A193T changes. The results also showed for the first time that H1N2 viruses were prominent in South Africa during the 2001-2002 influenza season, accounting for over 90% of the A(H1) cases in our study, and infecting both children (29/31) and the elderly (11/13). Phylogenetic analysis of the 65 H1N2 viruses we identified, in conjunction with the 56 recent H1N2 viruses currently available in the database, provided a comprehensive view of the circulation and evolution of distinct clades of H1N2 viruses in a temporal manner between early 2001 and mid-2003, shortly after the appearance of these recent reassortant viruses in or near year 2000.

To present the costs of fatal and non-fatal days-away-from-work injuries in 50 construction occupations. Our results also provide indirect evidence on the cost exposure of alternative construction workers such as independent contractors, on-call or day labor, contract workers, and temporary workers. We combine data from the Bureau of Labor Statistics on average annual incidence from 2000 to 2002 with updated per-case costs from an existing cost model for occupational injuries. The Current Population Survey provides data on the percentage of alternative construction workers. Construction laborers and carpenters were the two costliest occupations, with 40% of the industry's injury costs. The 10 costliest construction occupations also have a high percentage of alternative workers. The construction industry has both a high rate of alternative employment and high costs of work injury. Alternative workers, often lacking workers' compensation, are especially exposed to injury costs.

Sulfur Dioxide Emission Rates from Kilauea Volcano, Hawai`i, an Update: 2002-2006

USGS Publications Warehouse

Elias, Tamar; Sutton, A.J.

2007-01-01

Introduction Sulfur dioxide (SO2) emission rates from Kilauea Volcano were first measured by Stoiber and Malone (1975) and have been measured on a regular basis since 1979 (Greenland and others, 1985; Casadevall and others, 1987; Elias and others, 1998; Sutton and others, 2001, Elias and Sutton, 2002, Sutton and others, 2003). Compilations of SO2 emission-rate and wind-vector data from 1979 through 2001 are available on the web. (Elias and others, 1998 and 2002). This report updates the database through 2006, and documents the changes in data collection and processing that have occurred during the interval 2002-2006. During the period covered by this report, Kilauea continued to release SO2 gas predominantly from its summit caldera and east rift zone (ERZ) (Elias and others, 1998; Sutton and others, 2001, Elias and others, 2002, Sutton and others, 2003). These two distinct sources are always measured independently (fig.1). Sulphur Banks is a minor source of SO2 and does not contribute significantly to the total emissions for Kilauea (Stoiber and Malone, 1975). From 1979 until 2003, summit and east rift zone emission rates were derived using vehicle- and tripod- based Correlation Spectrometry (COSPEC) measurements. In late 2003, we began to augment traditional COSPEC measurements with data from one of the new generation of miniature spectrometer systems, the FLYSPEC (Horton and others, 2006; Elias and others, 2006, Williams-Jones and others, 2006).

Purpose: To delineate changing trends in radical external beam radiotherapy (EBRT) for prostate cancer in Japan. Methods and Materials: Data from 841 patients with clinically localized prostate cancer treated with EBRT in the Japanese Patterns of Care Study (PCS) from 1996 to 2005 were analyzed. Results: Significant increases in the proportions of patients with stage T1 to T2 disease and decrease in prostate-specific antigen values were observed. Also, there were significant increases in the percentages of patients treated with radiotherapy by their own choice. Median radiation doses were 65.0 Gy and 68.4 Gy from 1996 to 1998 and from 1999more » to 2001, respectively, increasing to 70 Gy from 2003 to 2005. Moreover, conformal therapy was more frequently used from 2003 to 2005 (84.9%) than from 1996 to 1998 (49.1%) and from 1999 to 2001 (50.2%). On the other hand, the percentage of patients receiving hormone therapy from 2003 to 2005 (81.1%) was almost the same as that from 1996 to 1998 (86.3%) and from 1999 to 2001 (89.7%). Compared with the PCS in the United States, patient characteristics and patterns of treatments from 2003 to 2005 have become more similar to those in the United States than those from 1996 to 1998 and those from 1999 to 2001. Conclusions: This study indicates a trend toward increasing numbers of patients with early-stage disease and increasing proportions of patients treated with higher radiation doses with advanced equipment among Japanese prostate cancer patients treated with EBRT during 1996 to 2005 survey periods. Patterns of care for prostate cancer in Japan are becoming more similar to those in the United States.« less

Effect of privatization of the drug distribution system on drug prices in Malaysia.

Previous studies on anti-infective and cardiovascular drugs have shown extraordinary price increases following privatization of the Malaysian drug distribution system. Therefore, it was felt that there was a need to undertake a full-scale study to evaluate the effect of privatization of the Malaysian drug distribution system on drug prices. To compare pre-privatization drug prices with post-privatization drug prices, and to compare the prices with international reference prices (IRPs). Five hundred and sixty-four drugs were listed in price lists for 1994, 1995-1996, 1997-2000 and 2001-2003. The 1994 data were taken as the pre-privatization prices, and all other lists were considered to be post-privatization prices. The pre-privatization prices (1994) were compared with those in 1995-1996. The prices in 1995-1996 were compared with those in 1997-2000, and the 1997-2000 prices were compared with those in 2001-2003. Furthermore, the 2001-2003 prices were compared with the median IRPs taken from Management Sciences for Health. The prices increased by 10.42% in 1995-1996, decreased by 3.37% in 1997-2000, and increased by 64.04% in 2001-2003. The increase in prices does not follow any pricing formula but is influenced by free market principles. The commonly used generic drugs showed enormously higher prices compared with the IRPs. Some of the prices increased several hundred-fold compared with the previous year, showing that no pricing formula has been followed. Increasing prices over the years may lead to higher expenditures and a hurdle to drug accessibility. A rational pricing structure is needed for transparent pricing, and government involvement and the formation of a medicine pricing policy seems vital.

South Africa has one of the highest HIV prevalences in the world, and compared with other sectors of the national economy, the construction industry is disproportionately adversely affected. Using data collected nationally from more than 57,000 construction workers, HIV infection among South African construction workers was estimated, together with an assessment of the association between worker HIV serostatus and worker characteristics of gender, age, nature of employment, occupation, and HIV testing history. The HIV infection of construction workers was estimated to be lower than that found in a smaller 2008 sample. All worker characteristics are significantly associated with HIV serostatus. In terms of most at-risk categories: females are more at risk of HIV infection than males; workers in the 30-49 year old age group are more at risk than other age groups; workers employed on a less permanent basis are more at risk; as are workers not having recently tested for HIV. Among occupations in the construction industry, general workers, artisans, and operator/drivers are those most at risk. Besides yielding more up-to-date estimated infection statistics, this research also identifies vulnerable sub-groups as valuable pointers for more targeted workplace interventions by construction firms.

The locality theorem in density-functional theory (DFT) states that the functional derivative of the Hohenberg-Kohn universal functional can be expressed as a local multiplicative potential function, and this is the basis of DFT and of the successful Kohn-Sham model. Nesbet has in several papers [Phys. Rev. A 58, R12 (1998); ibid.65, 010502 (2001); Adv. Quant. Chem, 43, 1 (2003)] claimed that this theorem is in conflict with fundamental quantum physics, and as a consequence that the Hohenberg-Kohn theory cannot be generally valid. We have commented upon these works [Comment, Phys. Rev. A 67, 056501 (2003)] and recently extended the argumentsmore » [Adv. Quantum Chem. 43, 95 (2003)]. We have shown that there is no such conflict and that the locality theorem is inherently exact. In the present work we have furthermore verified this numerically by constructing a local Kohn-Sham potential for the 1s2s{sup 3}S state of helium that generates the many-body electron density and shown that the corresponding 2s Kohn-Sham orbital eigenvalue agrees with the ionization energy to nine digits. Similar result is obtained with the Hartree-Fock density. Therefore, in addition to verifying the locality theorem, this result also confirms the so-called ionization-potential theorem.« less

India being a developing country has tremendous demand of physical infrastructure and construction work as a result there is a raising demand of construction workers. Workers in construction industry are mainly migratory and employed on contract or subcontract basis. These workers face temporary relationship between employer and employee, uncertainty in working hours, contracting and subcontracting system, lack of basic continuous employment, lack basic amenities, and inadequacy in welfare schemes. To estimate the prevalence of respiratory and dermatological symptoms among migratory construction workers. This cross-sectional study was conducted in Manipal, Karnataka, among 340 male migratory construction workers. A standard modified questionnaire was used as a tool by the interviewer and the physical examination of the workers was done by a physician. The statistical analysis was done using Statistical Package for the Social Sciences (SPSS) version 15.0. Eighty percent of the workers belong to the age group of 18-30 years. The mean age of the workers was 26 ± 8.2 years. Most (43.8%) of the workers are from West Bengal followed by those from Bihar and Jharkhand. The rates of prevalence of respiratory and dermatological symptoms were 33.2% and 36.2%, respectively. The migrant construction workers suffer from a high proportion of respiratory and dermatological problems.

Inhale, in colaboration with Pfizer and Aventis Pharma (formerly Hoechst Marion Roussel; HMR), is developing an insulin formulation utilizing its pulmonary delivery technology for macromolecules for the potential treatment of type I and II diabetes. By July 2001, the phase III program had been completed and the companies had begun to assemble data for MAA and NDA filings; however, it was already clear at this time that additional data might be required for filing. By December 2001, it had been decided that the NDA should include an increased level of controlled, long-term pulmonary safety data in diabetic patients and a major study was planned to be completed in 2002, with the NDA filed thereafter (during 2002). US-05997848 was issued to Inhale Therapeutic Systems in December 1999, and corresponds to WO-09524183, filed in February 1995. Equivalent applications have appeared to date in Australia, Brazil, Canada, China, Czech Republic, Europe, Finland, Hungary, Japan, Norway, New Zealand, Poland and South Africa. This family of applications is specific to pulmonary delivery of insulin. In February 1999, Lehman Brothers gave this inhaled insulin a 60% probability of reaching market, with a possible launch date of 2001. The analysts estimated peak sales at $3 billion in 2011. In May 2000, Aventis predicted that estimated peak sales would be in excess of $1 billion. In February 2000, Merrill Lynch expected product launch in 2002 and predicted that it would be a multibillion-dollar product. Analysts Merril Lynch predicted, in September and November 2000, that the product would be launched by 2002, with sales in that year of e75 million, rising to euro 500 million in 2004. In April 2001, Merrill Lynch predicted that filing for this drug would occur in 2001. Following the report of the potential delay in regulatory filing, issued in July 2001, Deutsche Banc Alex Brown predicted a filing would take place in the fourth quarter of 2002 and launch would take place in the first quarter of 2003. In August 2001, Lehman Brothers predicted that launch would take place in the first half of 2002 and that the product would make sales of $475 million in 2003, rising to $875 million in 2004. In the same month, Deutsche Bank predicted that there would be worldwide sales of $50 million in 2003, rising to $400 million in 2005. At this time, analysts at Credit Suisse predicted a launch of the product in 2003, with sales of $70 million in that year, rising to $550 million in 2005. By October 2001, Deutsche Bank predicted sales of $50 million in 2004 and $250 million in 2005. In September 2001, Morgan Stanley predicted sales of $500 million in 2002, rising to $1250 million in 2006.

While exercise has been shown to be beneficial for some musculoskeletal pain conditions, construction workers who are regularly burdened with musculoskeletal pain may engage less in leisure-time physical activity (LTPA) due to pain. In a small pilot study, we investigate how musculoskeletal pain may influence participation in LTPA among construction workers. A sequential explanatory mixed-methods design was employed using a jobsite-based survey (n = 43) among workers at two commercial construction sites and one focus group (n = 5). Over 93% of these construction workers reported engaging in LTPA and 70% reported musculoskeletal pain. Fifty-seven percent of workers who met either moderate or vigorous LTPA guidelines reported lower extremity pain (i.e., ankle, knee) compared with 21% of those who did not engage in either LTPA (P = 0.04). Focus group analyses indicate that workers felt they already get significant physical activity out of their job because they are "moving all the time and not sitting behind a desk." Workers also felt they "have no choice but to work through pain and discomfort [as the worker] needs to do anything to get the job done." Pilot study findings suggest that construction workers not only engage in either moderate or vigorous LTPA despite musculoskeletal pain but workers in pain engage in more LTPA than construction workers without pain. © 2014 Wiley Periodicals, Inc.

Reflections on the health workers' strike at Malawi's major tertiary hospital, QECH, Blantyre, 2001: a case study.

Muula, A S; Phiri, A

2003-03-01

Health workers and support staff at Malawi's major referral hospital, the Queen Elizabeth Central Hospital, Blantyre, were on strike between 5th and 19th October 2001. The health workers' grievances included: lack of risk allowances; poor professional allowances; low salaries; and low housing allowances. The strike resulted in almost total closure of the 1500-bed hospital; only the burns and orthopaedic wards continued to serve patients. Volunteer staff, comprising the Red Cross, and nursing and medical students provided services. Verbal and written threats by the authorities had minimal effect on terminating the strike; rather, they encouraged the resolve to continue with the industrial action. We report aspects of the genesis, progress and resolution of the strike. Although not much seems to have been achieved, both the employer and the workers need to draw lessons from the experience.

Examine trends and patterns of work-related musculoskeletal disorders (WMSDs) among construction workers in the USA, with an emphasis on older workers. WMSDs were identified from the 1992-2014 Survey of Occupational Injuries and Illnesses (SOII), and employment was estimated from the Current Population Survey (CPS). Risk of WMSDs was measured by number of WMSDs per 10 000 full-time equivalent workers and stratified by major demographic and employment subgroups. Time series analysis was performed to examine the trend of WMSDs in construction. The number of WMSDs significantly dropped in the US construction industry, following the overall injury trends. However, the rate of WMSDs in construction remained higher than in all industries combined; the median days away from work increased from 8 days in 1992 to 13 days in 2014, and the proportion of WMSDs for construction workers aged 55 to 64 years almost doubled. By occupation, construction labourers had the largest number of WMSD cases, while helpers, heating and air-conditioning mechanics, cement masons and sheet metal workers had the highest rates of WMSDs. The major cause of WMSDs in construction was overexertion, and back injuries accounted for more than 40% of WMSDs among construction workers. The estimated wage loss for private wage-and-salary construction workers was $46 million in 2014. Construction workers continue to face a higher risk of WMSDs. Ergonomic solutions that reduce overexertion-the primary exposure for WMSDs-should be adopted extensively at construction sites, particularly for workers with a higher risk of WMSDs.

There is mounting evidence that language comprehension involves the activation of mental imagery of the content of utterances (Barsalou, 1999; Bergen, Chang, & Narayan, 2004; Bergen, Narayan, & Feldman, 2003; Narayan, Bergen, & Weinberg, 2004; Richardson, Spivey, McRae, & Barsalou, 2003; Stanfield & Zwaan, 2001; Zwaan, Stanfield, & Yaxley, 2002).…

A system to test the ground surface conditions of construction sites--for safe and efficient work without physical strain.

PubMed

Koningsveld, Ernst; van der Grinten, Maarten; van der Molen, Henk; Krause, Frank

2005-07-01

Ground surface conditions on construction sites have an important influence on the health and safety of workers and their productivity. The development of an expert-based "working conditions evaluation" system is described, intended to assist site managers in recognising unsatisfactory ground conditions and remedying these. The system was evaluated in the period 2002-2003. The evaluation shows that companies recognize poor soil/ground conditions as problematic, but are not aware of the specific physical workload hazards. The developed methods allow assessment of the ground surface quality and selection of appropriate measures for improvement. However, barriers exist at present to wide implementation of the system across the industry. Most significant of these is that responsibility for a site's condition is not clearly located within contracting arrangements, nor is it a topic of serious negotiation.

Employment-based retirement plan participation: geographic differences and trends, 2010.

PubMed

Copeland, Craig

2011-10-01

LATEST DATA: This Issue Brief examines the level of participation by workers in public- and private-sector employment-based pension or retirement plans, based on the U.S. Census Bureau's March 2011 Current Population Survey (CPS), the most recent data currently available (for year-end 2010). SPONSORSHIP RATE: Among all working-age (21-64) wage and salary employees, 54.2 percent worked for an employer or union that sponsored a retirement plan in 2010. Among full-time, full-year wage and salary workers ages 21-64 (those with the strongest connection to the work force), 61.6 percent worked for an employer or union that sponsors a plan. PARTICIPATION LEVEL: Among full-time, full-year wage and salary workers ages 21-64, 54.5 percent participated in a retirement plan. TREND: This is virtually unchanged from 54.4 percent in 2009. Participation trends increased significantly in the late 1990s, and decreased in 2001 and 2002. In 2003 and 2004, the participation trend flattened out. The retirement plan participation level subsequently declined in 2005 and 2006, before a significant increase in 2007. Slight declines occurred in 2008 and 2009, followed by a flattening out of the trend in 2010. AGE: Participation increased with age (61.4 percent for wage and salary workers ages 55-64, compared with 29.2 percent for those ages 21-24). GENDER: Among wage and salary workers ages 21-64, men had a higher participation level than women, but among full-time, full-year workers, women had a higher percentage participating than men (55.5 percent for women, compared with 53.8 percent for men). Female workers' lower probability of participation among wage and salary workers results from their overall lower earnings and lower rates of full-time work in comparison with males. RACE: Hispanic wage and salary workers were significantly less likely than both white and black workers to participate in a retirement plan. The gap between the percentages of black and white plan participants that exists overall narrows when compared across earnings levels. GEOGRAPHIC DIFFERENCES: Wage and salary workers in the South and West had the lowest participation levels (Florida had the lowest percentage, at 43.7 percent) while the upper Midwest, Mid-Atlantic, and Northeast had the highest levels (West Virginia had the highest participation level, at 64.2 percent). White, more highly educated, higher-income, and married workers are more likely to participate than their counterparts.

2002-08-01

We wanted to explore the risk of asthma among male workers of the construction industry. All Finnish male construction industry workers and all those employed in administrative work were followed for asthma incidence through a register linkage in 1986 through 1998. Age-adjusted relative risks (RR) were estimated for 24 construction occupations. The risk was increased in nearly all construction occupations studied, but it was highest among welders and flame cutters (RR 2.34), asphalt roofing workers (RR 2.04), plumbers (RR 1.90), and brick layers and tile setters (RR 1.83). Only 45 (2%) of the cases of asthma among construction workers had been recognized as occupational asthma. Construction industry workers have an increased risk of adult-onset persistent asthma and cases of occupational asthma caused by well-established causative agents have only a minor contribution to this overall asthma excess.

In many countries, it is common practice to attract and employ ethnic minority (EM) or migrant workers in the construction industry. This primarily occurs in order to alleviate the labor shortage caused by an aging workforce with a lack of new entrants. Statistics show that EM construction workers are more likely to have occupational fatal and nonfatal injuries than their local counterparts; however, the mechanism underlying accidents and injuries in this vulnerable population has been rarely examined. This study aims to investigate relationships among safety climate, safety behavior, and safety outcomes for EM construction workers. To this end, a theoretical research model was developed based on a comprehensive review of the current literature. In total, 289 valid questionnaires were collected face-to-face from 223 Nepalese construction workers and 56 Pakistani construction workers working on 15 construction sites in Hong Kong. Structural equation modelling was employed to validate the constructs and test the hypothesized model. Results show that there were significant positive relationships between safety climate and safety behaviors, and significant negative relationships between safety behaviors and safety outcomes for EM construction workers. This research contributes to the literature regarding EM workers by providing empirical evidence of the mechanisms by which safety climate affects safety behaviors and outcomes. It also provides insights in order to help the key stakeholders formulate safety strategies for EM workers in many areas where numerous EM workers are employed, such as in the U.S., the UK, Australia, Singapore, Malaysia, and the Middle East.

Macroinvertebrates were sampled in four headwater streams for two years (2001-2003) to establish baseline conditions for a study evaluating forestry best management practices. The Palmer Drought Severity Index indicated that the study site experienced a prolonged moderate to severe drought prior to study initiation, with year one of the study characterized as a moderate drought, while year two encompassed drought and initial rainfall recovery. Benthic macroinvertebrates were collected in streams during year one (December 2001/February 2002) and year two (December 2002/February 2003) using a multi-habitat sampling procedure. Individuals were identified to the lowest practical taxonomic level (mostly genus), and metrics including abundance, total number of taxa, and Ephemeroptera, Plecoptera, and Trichoptera (EPT) taxa were calculated. Repeated measures ANOVA identified differences in macroinvertebrate assemblages due to sampling period, with lower values for December 2001 relative to February 2003. Abundance and EPT taxa showed an increasing relationship with average daily flow in successive samples of the study. Initiation of drought conditions prior to the study adversely affected species composition (low numbers of EPT taxa and long lived taxa) and trophic structure (co-dominance of shredders, collectors, and predators).

Prediction of protein subcellular locations by GO-FunD-PseAA predictor.

The localization of a protein in a cell is closely correlated with its biological function. With the explosion of protein sequences entering into DataBanks, it is highly desired to develop an automated method that can fast identify their subcellular location. This will expedite the annotation process, providing timely useful information for both basic research and industrial application. In view of this, a powerful predictor has been developed by hybridizing the gene ontology approach [Nat. Genet. 25 (2000) 25], functional domain composition approach [J. Biol. Chem. 277 (2002) 45765], and the pseudo-amino acid composition approach [Proteins Struct. Funct. Genet. 43 (2001) 246; Erratum: ibid. 44 (2001) 60]. As a showcase, the recently constructed dataset [Bioinformatics 19 (2003) 1656] was used for demonstration. The dataset contains 7589 proteins classified into 12 subcellular locations: chloroplast, cytoplasmic, cytoskeleton, endoplasmic reticulum, extracellular, Golgi apparatus, lysosomal, mitochondrial, nuclear, peroxisomal, plasma membrane, and vacuolar. The overall success rate of prediction obtained by the jackknife cross-validation was 92%. This is so far the highest success rate performed on this dataset by following an objective and rigorous cross-validation procedure.

Risk compensation behaviours in construction workers' activities.

PubMed

Feng, Yingbin; Wu, Peng

2015-01-01

The purpose of this study was to test whether the construction workers have the tendency of engaging in risk compensation behaviours, and identify the demographic variables, which may influence the extent to which the construction workers may show risk compensation behaviours. Both quantitative (survey) and qualitative (interviews) approaches were used in this study. A questionnaire survey was conducted with all the construction workers on three building construction sites of a leading construction company in Australia. Semi-structured interviews were then conducted to validate the findings of the quantitative research. The findings indicate that workers tend to show risk compensation behaviours in the construction environment. The workers with more working experience, higher education, or having never been injured at work before have a higher tendency to show risk compensation in their activities than the others. The implication is that contractors need to assess the potential influence of workers' risk compensation behaviours when evaluating the effect of risk control measures. It is recommended that supervisors pay more attention to the behavioural changes of those workers who have more experience, higher education, and have never been injured before after the implementation of new safety control measures on construction site.

Onchocerciasis control in the Democratic Republic of Congo (DRC): challenges in a post-war environment.

To evaluate onchocerciasis control activities in the Democratic Republic of Congo (DRC) in the first 12 years of community-directed treatment with ivermectin (CDTI). Data from the National Programme for Onchocerciasis (NPO) provided by the National Onchocerciasis Task Force (NOTF) through the annual reports of the 21 CDTI projects for the years 2001-2012 were reviewed retrospectively. A hypothetical-inputs-process-outputs-outcomes table was constructed. Community-directed treatment with ivermectin expanded from 1968 communities in 2001 to 39 100 communities by 2012 while the number of community-directed distributors (CDD) and health workers (HW) multiplied. By 2012, there were ratios of 1 CDD per 262 persons and 1 HW per 2318 persons at risk. More than 80% of the funding came from the fiduciary funds of the African Programme for Onchocerciasis Control. The cost of treatment per person treated fell from US$ 1.1 in 2001 to US$ 0.1 in 2012. The therapeutic coverage increased from 2.7% (2001) to 74.2% (2012); the geographical coverage, from 4.7% (2001) to 93.9% (2012). Geographical coverage fell in 2005 due to deaths in loiasis co-endemic areas, and the therapeutic coverage fell in 2008 due to insecurity. Challenges to CDTI in DRC have been serious adverse reactions to ivermectin in loiasis co-endemic areas and political conflict. Targets for personnel or therapeutic and geographical coverages were not met. Longer term funding and renewed efforts are required to achieve control and elimination of onchocerciasis in DRC. © 2014 John Wiley & Sons Ltd.

Western Pond Turtle Head-starting and Reintroduction; 2002-2003 Progress Report.

Van Leuven, Susan; Allen, Harriet; Slavin, Kate

2004-02-01

This report covers the results of the western pond turtle head-starting and reintroduction project for the period of June 2002-September 2003. Wild hatchling western pond turtles from the Columbia River Gorge were reared at the Woodland Park and Oregon Zoos in 2002 and 2003 as part of the recovery effort for this Washington State endangered species. The objective of the program is to reduce losses to introduced predators like bullfrogs and largemouth bass by raising the hatchlings to a size where they are too large to be eaten by most of these predators. In 2002, 27 females from the twomore » Columbia Gorge populations were equipped with transmitters and monitored until they nested. Four more females carrying old transmitters were also monitored; only one of these transmitters lasted through the nesting season. In 2003, 30 females were monitored. Twenty-three of the females monitored in 2002 nested and produced 84 hatchlings. The hatchlings were collected in fall 2002 and reared in captivity at the Woodland Park and Oregon zoos in the head-start program. Twenty-seven of the turtles monitored in 2003 nested. Six of the turtles nested twice, producing a total of 33 nests. The nests will be checked in September and October 2003 for hatchlings. Of 121 head-started juvenile western pond turtles collected in the Columbia Gorge during the 2001 nesting season, 119 were released at three sites in the Columbia Gorge in 2002, and 2 held over for additional growth. Of 86 turtles reared in the head-start program at the Woodland Park and Oregon Zoos fall 2002 through summer 2003, 67 were released at sites in the Columbia Gorge in summer of 2003, and 15 held over for more growth. Fifty-nine juveniles were released at Pierce National Wildlife Refuge in July 2002, and 51 released there in July 2003. Sixteen of those released in 2002 and 16 released in 2003 were instrumented with radio transmitters and monitored for varying amounts of time for survival and habitat use between the time of release and August 2003, together with juveniles from the 2001 release which were monitored from June 2001 through August 2003, and juveniles from the 2000 release which were monitored from August 2000 through August 2003. The number of functioning transmitters varied due to transmitter failures and detachments, and availability of replacement transmitters, as well as opportunities to recapture turtles. By August 15, 2003, a total of 39 turtles were being monitored: 6 from the 2000 release, 8 from the 2001 release, 10 from the 2002 release, and 15 from the 2003 release. During the 2002 field season trapping effort, 280 turtles were captured in the Columbia Gorge, including 236 previously head-started turtles. During the 2003 trapping season, 349 turtles were captured in the Columbia Gorge; 304 of these had been head-started. These recaptures, together with confirmed nesting by head-start females and visual re-sightings, indicate the program is succeeding in boosting juvenile recruitment to increase the populations. Records were also collected on 160 individual painted turtles captured in 2002 and 189 painted turtles captured in 2003 during trapping efforts at Pierce NWR, to gather baseline information on this native population. Eight female painted turtles were monitored by telemetry during the 2002 nesting season; 4 nests were recorded for these animals, plus 35 nests located incidentally. Preferred habitat for nesting was identified based on the telemetry results, to be considered in anticipating future turtle habitat needs and in management planning at Pierce NWR. Bonneville Power Administration (BPA) funding supported activities in the Columbia River Gorge from June 2002 through September 2003.« less

The need of astrometric observations for the fit the dynamical models of the natural satellites appears in the 1970's when the computers were able to analyse large sets of data. Then, theoreticians started to search for numerous data from the observers. The IAU commission 20 encouraged then the creation of a Data Center, under the responsibility of the Working Group on Natural satellites, to gather the data and make then available for the community. Today, the data center gathers near 90 existing data, available on the web site of IMCCE (Paris) with a mirror at SAI (Moscow). The Web address is: www.imcce.fr/nsdc The available data are, for the satellites of: -Mars: 4558 observations (1877-1988) -Jupiter: Galilean: 12000 observations (1891-2001); inner: 730 (1954-2000); outer: 3300 for J6 to J13 (1894-2003) and 1250 from J17 to fainters (1975-2004) -Saturn: main: 48 000 observations (1874-2001); inner and coorbital:1058 (1966-2002); outer: 705 observations of Phoebe (1904-2004) and 505 of the fainters (2000-2005) -Uranus: main: 12 591 observations (1982-2003); faint: 130 (1994) -Neptune: 1384 observations of Triton (1989-2001); 495 of Nereide (1949-2004); 200 of the outers (1984-2004) and 83 of the inners (1991-1997) -Pluto and asteroids: under construction We gather also 21213 eclipses and occultations (1652-1983), 542 mutual events (1985-1991) of the Galilean satellites and 66 mutual events (1995-1996) for the Saturnian satellites. This data base is made possible thanks to the help of R. Vieira-Martins, C. Veiga (Rio de Janeiro observatory) who provides data as recommended by the Data Center, G. Williams (MPC) who sends the observations of the faint outer satellites of the giant planets gathered as asteroidal observations and D. Pascu who made efforts to complete the reduction of his data.

Hispanic construction workers experience high rates of occupational injury, likely influenced by individual, organizational, and social factors. To characterize the safety climate of Hispanic construction workers using worker, contractor, and supervisor perceptions of the workplace. We developed a 40-item interviewer-assisted survey with six safety climate dimensions and administered it in Spanish and English to construction workers, contractors, and supervisors. A safety climate model, comparing responses and assessing contributing factors was created based on survey responses. While contractors and construction supervisors' (n = 128) scores were higher, all respondents shared a negative perception of safety climate. Construction workers had statistically significantly lower safety climate scores compared to supervisors and contractors (30·6 vs 46·5%, P<0·05). Safety climate scores were not associated with English language ability or years lived in the United States. We found that Hispanic construction workers in this study experienced a poor safety climate. The Hispanic construction safety climate model we propose can serve as a framework to guide organizational safety interventions and evaluate safety climate improvements.

The penalty point system was introduced in Italy in June 2003. The aim of this study was to evaluate the health effects of this legislation in the Lazio region. Poisson models were used to compare emergency department visits, hospitalizations and death between the pre-law and post-law periods (July 2001-June 2003; July 2003-June 2004). The emergency department visit rate ratio (RR) of the two periods was 0.87 (95% confidence interval (CI) 0.86 to 0.88); the corresponding hospital admission RR was 0.87 (95% CI 0.84 to 0.9). The death RR was 0.93 (95% CI 0.82 to 1.05). After the legislation was introduced, there were fewer visits to the emergency department, hospitalizations and death from road traffic injuries. However, the effect was lower than expected, and it decreased over time.

We characterize and compare the self-reported physical exposures, work tasks, and OSHA-10 training in a non-probabilistic sample of temporary and payroll construction workers. In June 2016, a total of 250 payroll and temporary general laborers employed at Florida construction sites completed a survey at the job site as part of the falls reported among minority employees (FRAME) study. Workers employed through temp agencies (57.1%) were significantly more likely to report moving or lifting materials more than 100 pounds than payroll workers (38.5%; P < 0.01). Temporary construction workers with 10-hour OSHA training (22.2%) spent significantly less time with intense hand use/awkward hand posture than temporary workers without 10-hour OSHA training (46.9%; P = 0.048). Temp construction workers with OSHA 10-hour training reported less hazardous physical postures than workers without the same training.

Annual Cycles of Multiyear Sea Ice Coverage of the Arctic Ocean: 1999-2003

NASA Technical Reports Server (NTRS)

Kwok, R.

2004-01-01

For the years 1999-2003, we estimate the time-varying perennial ice zone (PIZ) coverage and construct the annual cycles of multiyear (MY, including second year) ice coverage of the Arctic Ocean using QuikSCAT backscatter, MY fractions from RADARSAT, and the record of ice export from satellite passive microwave observations. An area balance approach extends the winter MY coverage from QuikSCAT to the remainder of the year. From these estimates, the coverage of MY ice at the beginning of each year is 3774 x 10(exp 3) sq km (2000), 3896 x 10(exp 3) sq km (2001), 4475 x 10(exp 3) sq km (2002), and 4122 x 10(exp 3) sq km (2003). Uncertainties in coverage are approx.150 x 10(exp 3) sq km. In the mean, on 1 January, MY ice covers approx.60% of the Arctic Ocean. Ice export reduces this coverage to approx.55% by 1 May. From the multiple annual cycles, the area of first-year (FY) ice that survives the intervening summers are 1192 x 10(exp 3) sq km (2000), 1509 x 10(exp 3) sq km (2001), and 582 x 10(exp 3) sq km (2002). In order for the MY coverage to remain constant from year to year, these replenishment areas must balance the overall area export and melt during the summer. The effect of the record minimum in Arctic sea ice area during the summer of 2002 is seen in the lowest area of surviving FY ice of the three summers. In addition to the spatial coverage, the location of the PIZ is important. One consequence of the unusual location of the PIZ at the end of the summer of 2002 is the preconditioning for enhanced export of MY ice into the Barents and Kara seas. Differences between the minimums in summer sea ice coverage from our estimates and passive microwave observations are discussed.

Do work-place initiated measures reduce sickness absence? Preventive measures and sickness absence among older workers in Norway.

PubMed

Midtsundstad, Tove I; Nielsen, Roy A

2014-03-01

The article examines whether preventive measures and work adjustments at the establishment level affects sickness absence among workers aged 50 years and older. We combine survey data from a representative sample of 713 Norwegian companies, mapping the prevalence of preventive health measures in the work place in 2005, with register data on sickness absence and demographic variables for workers aged 50 years or older in 2001 and 2007. By means of a difference-in-differences approach, we compare changes and differences in the likelihood of sickness absence among the sample group, with and without the various measures/ instruments in 2005 respectively. In general, work-place preventive measures at the establishment level have not contributed to reducing the probability for sickness absence among workers aged 50 years and older. However, analyses comparing differences between industries find that the work-place measures have had a positive effect on public administration employees. Whether work-place preventive initiatives influence levels of sickness absence seems to be contingent on sector and industry. Therefore, work-place measures may be more effective in the public administration sector where most employees have office jobs compared to sectors such as manufacturing, construction and transportation, where many employees have manual work and more physical demanding jobs. Work-place initiatives thus seem to have less effect on preventing sickness absence in sectors dominated by manual labour.

Systematic review: chronic obstructive pulmonary disease and construction workers

Abstract Background Between 15 and 20% of prevalent cases of chronic obstructive pulmonary disease (COPD) have been attributed to occupational exposures to vapours, gases, dusts and fumes. Dust at construction sites is still a challenge, but no overview exists of COPD among construction workers. Aims To assess the occurrence of COPD among construction workers. Methods We performed a systematic search in PubMed and Embase between 1 January 1990 and 31 August 2016 in order to identify epidemiological studies with a risk estimate for either COPD morbidity/mortality or a spirometry-based definition of airway obstruction among workers in the construction industry. The authors independently assessed studies to determine their eligibility and performed a quality assessment of the included papers. Results Twelve studies were included. Nine studies found a statistically significant association between COPD and work in the construction industry, although only among never-smokers in one study and only for the period after 2000 in another study. One study found that the annual decline in forced expiratory volume in 1 s was significantly higher among construction workers compared with bus drivers. Conclusions This review suggests that COPD occurs more often among construction workers than among workers who are not exposed to construction dust. It is not possible to draw any conclusions on specific subgroups as most studies analysed construction workers as one united group. In addition, no potential exposure–effect relationship could be identified. PMID:28204712

2004-01-01

Water-quality samples were collected from 20 surface-water sites and 11 ground-water sites on the Prairie Band Potawatomi Reservation in northeastern Kansas in an effort to describe existing water-quality conditions on the reservation and to compare water-quality conditions to results from previous reports published as part of a multiyear cooperative study with the Prairie Band Potawatomi Nation. Water is a valuable resource to the Prairie Band Potawatomi Nation as tribal members use the streams draining the reservation, Soldier, Little Soldier, and South Cedar Creeks, to fulfill subsistence hunting and fishing needs and as the tribe develops an economic base on the reservation. Samples were collected once at 20 surface-water monitoring sites during June 2001, and quarterly samples were collected at 5 of the 20 monitoring sites from May 2001 through August 2003. Ground-water-quality samples were collected once from seven wells and twice from four wells during April through May 2003 and in August 2003. Surface-water-quality samples collected from May through August 2001 were analyzed for physical properties, nutrients, pesticides, fecal indicator bacteria, and total suspended solids. In November 2001, an additional analysis for dissolved solids, major ions, trace elements, and suspended-sediment concentration was added for surface-water samples. Ground-water samples were analyzed for physical properties, dissolved solids, major ions, nutrients, trace elements, pesticides, and fecal indicator bacteria. Chemical oxygen demand and volatile organic compounds were analyzed in a sample from one monitoring well located near a construction and demolition landfill on the reservation. Previous reports published as a part of this ongoing study identified total phosphorus, triazine herbicides, and fecal coliform bacteria as exceeding their respective water-quality criteria in surface water on the reservation. Previous ground-water assessments identified occasional sample concentrations of dissolved solids, sodium, sulfate, boron, iron, and manganese as exceeding their respective water-quality criteria. Forty percent of the 65 surface-water samples analyzed for total phosphorus exceeded the aquatic-life goal of 0.1 mg/L (milligrams per liter) established by the U.S. Environmental Protection Agency (USEPA). Concentrations of dissolved solids and sodium occasionally exceeded USEPA Secondary Drinking-Water Regulations and Drinking-Water Advisory Levels, respectively. One of the 20 samples analyzed for atrazine concentrations exceeded the Maximum Contaminant Level (MCL) of 3.0 ?g/L (micrograms per liter) as an annual average established for drinking water by USEPA. A triazine herbicide screen was used on 63 surface-water samples, and triazine compounds were frequently detected. Triazine herbicides and their degradates are listed on the USEPA Contaminant Candidate List. Nitrite plus nitrate concentrations in two ground-water samples from one monitoring well exceeded the MCL of 10 mg/L established by USEPA for drinking water. Arsenic concentrations in two samples from one monitoring well also exceeded the proposed MCL of 10 ?g/L established by the USEPA for drinking water. Concentrations of dissolved solids and sulfate in some ground-water samples exceeded their respective Secondary Drinking-Water Regulations, and concentrations exceeded the taste threshold of the USEPA?s Drinking-Water Advisory Level for sodium. Consequently, in the event that ground water on the reservation is to be used as a drinking-water source, additional treatment may be necessary to remove excess dissolved solids, sulfate, and sodium.

Relationships among Safety Climate, Safety Behavior, and Safety Outcomes for Ethnic Minority Construction Workers

2018-01-01

In many countries, it is common practice to attract and employ ethnic minority (EM) or migrant workers in the construction industry. This primarily occurs in order to alleviate the labor shortage caused by an aging workforce with a lack of new entrants. Statistics show that EM construction workers are more likely to have occupational fatal and nonfatal injuries than their local counterparts; however, the mechanism underlying accidents and injuries in this vulnerable population has been rarely examined. This study aims to investigate relationships among safety climate, safety behavior, and safety outcomes for EM construction workers. To this end, a theoretical research model was developed based on a comprehensive review of the current literature. In total, 289 valid questionnaires were collected face-to-face from 223 Nepalese construction workers and 56 Pakistani construction workers working on 15 construction sites in Hong Kong. Structural equation modelling was employed to validate the constructs and test the hypothesized model. Results show that there were significant positive relationships between safety climate and safety behaviors, and significant negative relationships between safety behaviors and safety outcomes for EM construction workers. This research contributes to the literature regarding EM workers by providing empirical evidence of the mechanisms by which safety climate affects safety behaviors and outcomes. It also provides insights in order to help the key stakeholders formulate safety strategies for EM workers in many areas where numerous EM workers are employed, such as in the U.S., the UK, Australia, Singapore, Malaysia, and the Middle East.

2006-09-01

Construction workers were and are considered temporary workers at many construction sites. Since World War II, large numbers of construction workers were employed at U.S. Department of Energy nuclear weapons sites for periods ranging from a few days to over 30 years. These workers performed tasks during new construction and maintenance, repair, renovation, and demolition of existing facilities. Such tasks may involve emergency situations, and may entail opportunities for significant radiation exposures. This paper provides data from interviews with more than 750 construction workers at two gaseous diffusion plants (GDPs) at Paducah, Kentucky, and Portsmouth, Ohio regarding radiation monitoring practices. The aim was to determine the extent to which workers believed they were monitored during tasks involving potential radiation exposures. The adequacy of monitoring practices is important for two reasons: (a) Protecting workers from exposures: Construction workers were employed by sub-contractors, and may frequently been excluded from safety and health programs provided to permanent employees; and (b) Supporting claims for compensation: The Energy Employees Occupational Illness Compensation Program Act (EEOICPA) requires dose reconstruction of radiation exposures for most workers who file a claim regarding cancer. The use of monitoring data for radiation to qualify a worker means that there should be valid and complete monitoring during the work time at the various nuclear plants or workers may be unfairly denied compensation. The worker interviews from Paducah and Portsmouth were considered especially useful because these sites were designated as Special Exposure Cohorts (SECs) and the workers did not have to have a dose reconstruction to qualify for compensation for most cancers. Therefore, their responses were less likely to be affected by compensation concerns. Interview questions included asking for information regarding whether monitoring was performed, how often, and the maintenance (calibration) of monitoring equipment (devices).

Improved accuracy of co-morbidity coding over time after the introduction of ICD-10 administrative data

2011-01-01

Background Co-morbidity information derived from administrative data needs to be validated to allow its regular use. We assessed evolution in the accuracy of coding for Charlson and Elixhauser co-morbidities at three time points over a 5-year period, following the introduction of the International Classification of Diseases, 10th Revision (ICD-10), coding of hospital discharges. Methods Cross-sectional time trend evaluation study of coding accuracy using hospital chart data of 3'499 randomly selected patients who were discharged in 1999, 2001 and 2003, from two teaching and one non-teaching hospital in Switzerland. We measured sensitivity, positive predictive and Kappa values for agreement between administrative data coded with ICD-10 and chart data as the 'reference standard' for recording 36 co-morbidities. Results For the 17 the Charlson co-morbidities, the sensitivity - median (min-max) - was 36.5% (17.4-64.1) in 1999, 42.5% (22.2-64.6) in 2001 and 42.8% (8.4-75.6) in 2003. For the 29 Elixhauser co-morbidities, the sensitivity was 34.2% (1.9-64.1) in 1999, 38.6% (10.5-66.5) in 2001 and 41.6% (5.1-76.5) in 2003. Between 1999 and 2003, sensitivity estimates increased for 30 co-morbidities and decreased for 6 co-morbidities. The increase in sensitivities was statistically significant for six conditions and the decrease significant for one. Kappa values were increased for 29 co-morbidities and decreased for seven. Conclusions Accuracy of administrative data in recording clinical conditions improved slightly between 1999 and 2003. These findings are of relevance to all jurisdictions introducing new coding systems, because they demonstrate a phenomenon of improved administrative data accuracy that may relate to a coding 'learning curve' with the new coding system.

Aerosols generated during construction activities are an integral part of building operations. Considering the nature of materials used in construction activities, respirable dust contains crystalline silica and particulates not otherwise specified (PNOS). Due to lack of data regarding the occupational health status of Iranian construction workers, the objective of this study was to evaluate occupational exposure to silica and to examine their respiratory health status. In this cross sectional study, 85 construction workers and 40 controls (without active exposure to construction dust) were studied. The workers' exposure to PNOS and silica aerosols was monitored by the NIOSH method No.0600 and a new Fourier transform infrared spectroscopy (FTIR)-based method, respectively. All subjects were also monitored for lung function parameters, such as forced expiratory volume/forced vital capacity (FEV 1 /FVC), peak expiratory flow rate (PEFR), forced expiratory flow (FEF 25-75 ), FVC, and FEV 1 . The mean exposure of workers to respirable PNOS and silica was 9.8 (0.35) and 0.13 (0.019) mg/m 3 , respectively. The groups of construction workers showed significant differences in exposure to PNOS ( P < 0.001) and silica ( P = 0.007). The mean pulmonary function parameters, including FEV 1 % and FVC%, were significantly lower among construction workers, compared to the control group ( P < 0.001 and P = 0.009, respectively). The pulmonary status of 51.8% of construction workers showed moderate restriction, while 4.70% exhibited obstruction. Considering the construction workers' excessive exposure to PNOS and silica, besides depressed lung function parameters, they can be classified as a high-risk group for respiratory diseases.

Although airborne respiratory irritants at the World Trade Center (WTC) site have been associated with asthma among WTC Ground Zero workers, little is known about asthma associated with work at the Staten Island landfill or barges. To evaluate the risk of asthma first diagnosed among Staten Island landfill and barge workers, we conducted a survey and multivariable logistic regression analysis regarding the association between Staten Island landfill and barge-related work exposures and the onset of post-9/11 asthma. Asthma newly diagnosed between September 11, 2001 and December 31, 2004 was reported by 100/1,836 (5.4%) enrollees. Jobs involving sifting, digging, welding, and steel cutting, enrollees with high landfill/barge exposure index scores or who were police and sanitation workers, and enrollees with probable posttraumatic stress disorder all had increased odds ratios for new-onset asthma. Post-9/11 asthma cumulative incidence among Staten Island landfill/barge workers was similar to that of other WTC disaster rescue and recovery workers. Am. J. Ind.

Serum PCB levels and congener profiles among US construction workers

PubMed Central

Herrick, Robert F; Meeker, John D; Hauser, Russ; Altshul, Larisa; Weymouth, George A

2007-01-01

Background The presence of PCB in caulking (sealant) material found in masonry buildings has been well-documented in several countries. A recent investigation of 24 buildings in the greater Boston area found that 8 buildings had high PCB levels in caulking materials used around window frames and in joints between masonry blocks. Workers removing caulking material have been shown to have elevated serum PCB levels. Methods This project compared serum PCB levels among male workers who installed and/or removed PCB-containing caulking material from buildings in the greater Boston area with reference serum PCB levels from 358 men from the same area. Serum PCB levels were measured in the same laboratory by liquid-liquid extraction, column chromatography clean-up and dual capillary column GC/microECD analysis. Results When the congener profiles were compared between the reference population and the construction workers, the serum levels of the more volatile, lighter PCBs (di-, tri-and tetrachloro, sum of IUPAC# 6–74) were substantially higher among the construction workers. One of the youngest workers had the lowest total serum PCB levels (sum of 57 congeners) of all 6 workers, but the contribution of more volatile (less chlorinated) PCB congeners (#16, 26,28,33,74,66, and 60) was markedly higher than in other 5 workers and reference men. Only this worker was working on a job that involved removing PCB caulking at the time of the blood sampling. Conclusion While the results of this pilot study are based upon small numbers (6 construction workers who handled PCB caulking), the serum PCB levels among the construction workers exceed the referents. Comparison of the congener profiles suggests that there are substantial differences between the construction workers and the general population samples. These differences, and the similarities of profiles among the construction workers strongly suggest that occupational contact with caulking material can be a major source of PCB exposure for construction workers.

Work-related cerebro-cardiovascular diseases in Korea.

PubMed

Kim, Dae-Seong; Kang, Seong-Kyu

2010-12-01

Cerebro-cardiovascular disease (CVD) is one of compensable occupational diseases in Korea as in Japan or Taiwan. However, most countries accept only cardiovascular diseases (ischemic heart diseases) as compensable occupational diseases if any, but not cerebrovascular diseases. Korea has a prescribed list of compensable occupational diseases. CVD was not included in the list until 1993. In the early 1990s, a case of cerebral infarction was accepted as occupational disease by the Supreme Court. The decision was based on the concept that workers' compensation system is one of the social security systems. In 1994, the government has established a diagnostic criterion of CVD. The crude rate of compensated cerebrovascular disease decreased by 60.0% from 18.5 in 2003 to 7.4 in 2008 per 100,000 workers, and that of compensated coronary heart disease decreased by 60.5% from 3.8 in 2003 to 1.5 in 2008 per 100,000 workers. The compensated cases of CVD dramatically increased and reached its peak in 2003. Since many preventive activities were performed by the government and employers, the compensated cases have slowly decreased since 2003 and sharply decreased after 2008 when the diagnostic criterion was amended. The strategic approach is needed essentially because CVDs are common, serious and preventable diseases which lead to economic burden.

Electrical fatalities among U.S. construction workers.

PubMed

Ore, T; Casini, V

1996-06-01

Over 2000 electrocution deaths were identified among U.S. construction workers from 1980 to 1991, with the highest mean annual crude mortality rate (2.5 per 100,000 people), and second highest mean age-adjusted rate (2.7 per 100,000 people) of all industries. Although the crude fatality rates showed a downward trend, construction workers are still about four times more likely to be electrocuted at work than are workers in all industries combined. Nearly 40% of the 5083 fatal electrocutions in all industries combined occurred in construction, and 80% were associated with industrial wiring, appliances, and transmission lines. Electrocutions ranked as the second leading cause of death among construction workers, accounting for an average of 15% of traumatic deaths in the industry from 1980 to 1991. The study indicates that the workers most at risk of electrical injury are male, young, nonwhite, and electricians, structural metal workers, and laborers. The most likely time of injury is 11 a.m. to 3 p.m. from June to August. Focusing prevention on these populations and characteristics through better methods of worker and supervisor electrical safety training, use of adequate protective clothing, and compliance with established procedures could minimize the average annual loss of 168 U.S. construction workers.

Silicosis mortality trends and new exposures to respirable crystalline silica - United States, 2001-2010.

Silicosis is a preventable occupational lung disease caused by the inhalation of respirable crystalline silica dust and can progress to respiratory failure and death. No effective specific treatment for silicosis is available; patients are provided supportive care, and some patients may be considered for lung transplantation. Chronic silicosis can develop or progress even after occupational exposure has ceased. The number of deaths from silicosis declined from 1,065 in 1968 to 165 in 2004. Hazardous occupational exposures to silica dust have long been known to occur in a variety of industrial operations, including mining, quarrying, sandblasting, rock drilling, road construction, pottery making, stone masonry, and tunneling operations. Recently, hazardous silica exposures have been newly documented during hydraulic fracturing of gas and oil wells and during fabrication and installation of engineered stone countertops. To describe temporal trends in silicosis mortality in the United States, CDC analyzed annual multiple cause-of-death data for 2001-2010 for decedents aged ≥15 years. During 2001-2010, a total of 1,437 decedents had silicosis coded as an underlying or contributing cause of death. The annual number of silicosis deaths declined from 164 (death rate† = 0.74 per 1 million population) in 2001 to 101 (0.39 per 1 million) in 2010 (p = 0.002). Because of new operations and tasks placing workers at risk for silicosis, efforts to limit workplace exposure to crystalline silica need to be maintained.

Systematic review: chronic obstructive pulmonary disease and construction workers.

Between 15 and 20% of prevalent cases of chronic obstructive pulmonary disease (COPD) have been attributed to occupational exposures to vapours, gases, dusts and fumes. Dust at construction sites is still a challenge, but no overview exists of COPD among construction workers. To assess the occurrence of COPD among construction workers. We performed a systematic search in PubMed and Embase between 1 January 1990 and 31 August 2016 in order to identify epidemiological studies with a risk estimate for either COPD morbidity/mortality or a spirometry-based definition of airway obstruction among workers in the construction industry. The authors independently assessed studies to determine their eligibility and performed a quality assessment of the included papers. Twelve studies were included. Nine studies found a statistically significant association between COPD and work in the construction industry, although only among never-smokers in one study and only for the period after 2000 in another study. One study found that the annual decline in forced expiratory volume in 1 s was significantly higher among construction workers compared with bus drivers. This review suggests that COPD occurs more often among construction workers than among workers who are not exposed to construction dust. It is not possible to draw any conclusions on specific subgroups as most studies analysed construction workers as one united group. In addition, no potential exposure-effect relationship could be identified. © The Author 2017. Published by Oxford University Press on behalf of the Society of Occupational Medicine.

Dicot weed populations were assessed in spring barley trials carried out in four three-years periods at 5-year intervals: 1990-1992, 1995-1997; 2001-2003 and 2006-2008. The overall aim of this research was to evaluate the changes in dicot-weed infestations in spring barley in fields of one region (Riga) of Latvia in sod-podzolic loamy sand soil. The results of the trials showed that Galeopsis spp, Stellaoria media, Viola orvensis and Chenopodium album were among the most frequent weed species in the periods of 1990-1992 and 1995-1997. The occurrence of C. album and V. arvensis increased during the periods of 2001-2003 and 2006-2008.

The Attitude of Construction Workers toward the Implementation of Occupational Health and Safety (OHS)

2018-02-01

Construction industry refers to one of the industries dealing with high accident rate. Besides its outdoor workplace involving many workers who usually work manually, the workers’ work culture and less awareness of occupational health and safety (OHS) are attributed to the high accident rate. This study explores some construction workers who are involved in some construction projects in big cities such as Bandung and Jakarta. The questionnaire-given to the construction workers focusing on stone construction, wood construction, and finishing session-reveals that the construction workers knowledge and understanding of nine Occupational Health and Safety (OHS) aspects reach above 50%. However, does not appear to reflect their knowledge and understanding of Occupational Health and Safety (OHS). The results of Focus Group Discussion (FGD) and an in-depth interview show that the fallacious implementation of Occupational Health and Safety (OHS) is attributed to their traditional “work culture”.

The Work Ability of Hong Kong Construction Workers in Relation to Individual and Work-Related Factors.

PubMed

Ng, Jacky Y K; Chan, Alan H S

2018-05-14

The shortage in Hong Kong of construction workers is expected to worsen in future due to the aging population and increasing construction activity. Construction work is dangerous and to help reduce the premature loss of construction workers due to work-related disabilities, this study measured the work ability of 420 Hong Kong construction workers with a Work Ability Index (WAI) which can be used to predict present and future work performance. Given the importance of WAI, in this study the effects of individual and work-related factors on WAI were examined to develop and validate a WAI model to predict how individual and work-related factors affect work ability. The findings will be useful for formulating a pragmatic intervention program to improve the work ability of construction workers and keep them in the work force.

2014-01-01

Highly pathogenic avian influenza A(H5N1) is endemic in poultry in Viet Nam. The country has experienced the third highest number of human infections with influenza A(H5N1) in the world. A study in Hanoi in 2001, before the epizootic that was identified in 2003, found influenza A(H5N1) specific antibodies in 4% of poultry market workers (PMWs). We conducted a seroprevalence survey to determine the seroprevalence of antibodies to influenza A(H5N1) among PMWs in Hanoi, Thaibinh and Thanhhoa provinces. We selected PMWs from five markets, interviewed them and collected blood samples. These were then tested using a horse haemagglutination inhibition assay and a microneutralization assay with all three clades of influenza A(H5N1) viruses that have circulated in Viet Nam since 2004. The overall seroprevalence was 6.1% (95% confidence interval: 4.6-8.3). The highest proportion (7.2%) was found in PMWs in Hanoi, and the majority of seropositive subjects (70.3%) were slaughterers or sellers of poultry. The continued circulation and evolution of influenza A(H5N1) requires comprehensive surveillance of both human and animal sites throughout the country with follow-up studies on PMWs to estimate the risk of avian-human transmission of influenza A(H5N1) in Viet Nam.

Methodology of Detailed Geophysical Examination of the Areas of World Recognized Religious and Cultural Artifacts

NASA Astrophysics Data System (ADS)

Eppelbaum, Lev

2010-05-01

It is obvious that noninvasive geophysical methods are the main interpreting tools at the areas of world recognized religious and cultural artifacts. Usually in these areas any excavations, drilling and infrastructure activity are forbidden or very strongly limited. According to field experience and results of numerous modeling (Eppelbaum, 1999, 2000, 2009a, 2009b; Eppelbaum and Itkis, 2001, 2003; Eppelbaum et al., 2000, 2001a, 2001b, 2003a, 2006a, 2006b, 2007, 2010, Itkis et al., 2003; Neishtadt et al., 2006), a set of applied geophysical methods may include the following types of surveys: (1) magnetic, (3) GPR (ground penetration radar), (3) gravity, (4) electromagnetic VLF (very low frequency), (5) ER (electric resistivity), (6) SP (self-potential), (7) IP (induced polarization), (8) SE (seismoelectric), and (9) NST (near-surface temperature). As it was shown in (Eppelbaum, 2005), interpretation ambiguity may be sufficiently reduced not only by integrated analysis of several geophysical methods, but also by the way of multilevel observations of geophysical fields. Magnetic, gravity and VLF measurements may be performed at different levels over the earth's surface (0.1 - 3 m), ER, SP and SE observations may be obtained with different depth of electrodes grounding (0.1 - 1 m), and NST sensor may be located at a depth of 0.8 - 2.5 m. GPR method usually allows measuring electromagnetic fields at various frequencies (with corresponding changing of the investigation depth and other parameters). Influence of some typical noise factors to geophysical investigations at archaeological sites was investigated in (Eppelbaum and Khesin, 2001). In many cases various constructions and walls are in the nearest vicinity of the examined artifacts. These constructions can be also utilized for carrying out geophysical measurements (magnetic, gravity and VLF) at different levels. Application of the modern ROV (remote operated vehicles) with registration of magnetic and VLF fields at the low altitudes (3-5 meters) will help geophysical cover all the studied area with a regular observation step (Eppelbaum, 2008). At the final step all these measurements (including results of the previous works) could be compiled to 4D models of different geophysical parameters (Eppelbaum and Ben-Avraham, 2002; Eppelbaum et al., 2010). Analysis of temperature field in the boreholes drilled in the vicinity of the studied site will permit to estimate the temperature (e.g., Eppelbaum et al., 2006c) in the historical period when this artifact was constructed and, correspondingly, utilize this characteristic for investigation of mechanical and other properties of the ancient building material. Studying of temporal variations of magnetic (e.g., Finkelstein and Eppelbaum) and VLF fields can be also used for determination of nature of some buried ancient remains. The geophysical investigations must be combined with geochemical, paleostructural, paleobiogeographical, paleomorphological and other methods (Eppelbaum et al., 2010). Application of informational parameters (Khesin et al., 1996; Eppelbaum et al., 2003b) will permit to present all available data by the use of integral convolution units.

A needle in a haystack? Uninsured workers in small businesses that do not offer coverage.

PubMed

Kronick, Richard; Olsen, Louis C

2006-02-01

To describe the insurance status of workers at small businesses, and to describe the status of uninsured persons by the employment characteristics (employment status, firm size, and whether the employer offers insurance) of the head of household. Data from the March and February 2001 Current Population Survey, and a survey of 2,830 small businesses in San Diego County conducted in 2001. The survey of small businesses was undertaken as part of a project testing the response of employers to offers of subsidized coverage. Employers were asked whether they offered insurance, and about the insurance status of their employees. The merged February-March 2001 CPS was used to identify the employment status, firm size, and employer-offering status for uninsured persons in the U.S. Telephone interviews with small businesses in San Diego County. Only 21 percent of the uninsured in the U.S. are full-time employees (or their dependents) in small businesses (<100 employees) that do not offer insurance. The employment status of the uninsured is heterogeneous: many work for large employers, small employers who do offer insurance, or are self-employed, part-time workers, or have no workers in the household. Although there are many small businesses in San Diego that do not offer coverage, most of them have very few uninsured workers. Over 50 percent of businesses that do not offer coverage have either zero or one uninsured worker. There are very few small businesses that do not offer coverage and that have substantial numbers of uninsured workers. These businesses are not quite as rare as a needle in a haystack, but they are very difficult to find. If all small businesses that do not offer insurance now could be persuaded to start offering coverage, and if all the full-time workers (and their dependents) in those businesses accepted insurance, the number of uninsured would decline by 21 percent--a significant decline, but leaving 80 percent of the problem untouched. If the prime target for programs of subsidized insurance are small businesses that do not offer coverage now and that have substantial numbers of uninsured workers, the target is very small.

Severity of electrical accidents in the construction industry in Spain.

Suárez-Cebador, Manuel; Rubio-Romero, Juan Carlos; López-Arquillos, Antonio

2014-02-01

This paper analyzes the severity of workplace accidents involving electricity in the Spanish construction sector comprising 2,776 accidents from 2003 to 2008. The investigation considered the impact of 13 variables, classified into 5 categories: Personal, Business, Temporal, Material, and Spatial. The findings showed that electrical accidents are almost five times more likely to have serious consequences than the average accident in the sector and it also showed how the variables of age, occupation, company size, length of service, preventive measures, time of day, days of absence, physical activity, material agent, type of injury, body part injured, accident location, and type of location are related to the severity of the electrical accidents under consideration. The present situation makes it clear that greater effort needs to be made in training, monitoring, and signage to guarantee a safe working environment in relation to electrical hazards. This research enables safety technicians, companies, and government officials to identify priorities and to design training strategies to minimize the serious consequences of electrical accidents for construction workers.

Wang, Lin; Zheng, You-fei; Yu, Qiang; Wang, En-li

2007-11-01

The Agricultural Production Systems Simulator (APSIM) was applied to simulate the 1999-2001 field experimental data and the 2002-2003 water use data at the Yucheng Experiment Station under Chinese Ecosystem Research Network, aimed to verify the applicability of the model to the wheat-summer maize continuous cropping system in North China Plain. The results showed that the average errors of the simulations of leaf area index (LAI), biomass, and soil moisture content in 1999-2000 and 2000-2001 field experiments were 27.61%, 24.59% and 7.68%, and 32.65%, 35.95% and 10.26%, respectively, and those of LAI and biomass on the soils with high and low moisture content in 2002-2003 were 26.65% and 14.52%, and 23.91% and 27.93%, respectively. The simulations of LAI and biomass accorded well with the measured values, with the coefficients of determination being > 0.85 in 1999-2000 and 2002-2003, and 0.78 in 2000-2001, indicating that APSIM had a good applicability in modeling the crop biomass and soil moisture content in the continuous cropping system, but the simulation error of LAI was a little larger.

HIV testing of construction workers in the Western Cape, South Africa.

Bowen, Paul; Govender, Rajen; Edwards, Peter; Cattell, Keith

2015-01-01

With an infection rate estimated at 14%, the South African construction industry is one of the economic sectors most adversely affected by the HIV/AIDS pandemic. Construction workers are considered a high-risk group. The provision and uptake of voluntary counselling and testing (VCT) is critical to reducing transmission rates. This study examined the testing behaviour of site-based construction workers in terms of demographic and lifestyle risk behaviour characteristics to help inform better strategies for work-based interventions by construction firms. A total of 512 workers drawn from six firms operating on 18 construction sites in the Western Cape province participated in the study. Twenty-seven per cent of the participants reported never having been tested for HIV. Results indicate that females (aOR = 4.45, 95% CI, 1.25-15.82), older workers (aOR = 1.40, 95% CI, 1.08-1.81), permanent workers (aOR = 1.67, 95% CI, 1.11-2.50) and workers whom had previously used a condom (aOR = 1.93, 95% CI, 1.02-3.65) were significantly more likely to have been tested. Ethnicity was not significantly related to prior testing. Identification of these subgroups within the industry has implications for the development of targeted work-based intervention programmes to promote greater HIV testing among construction workers in South Africa.

Risky business: when mom and pop buy health insurance for their employees.

PubMed

Gabel, Jon R; Pickreign, Jeremy D

2004-04-01

The economics of small group insurance makes offering health benefits to employees a risky business. Surveys of employers from 1989 to 2003 reveal that more rapid premium increases are forcing small firms to impose higher cost-sharing. In 2003, premiums for small firms (3-199 workers) increased 15.5 percent, outpacing the 13.2 percent increase for large firms (200+ workers). From 2000 to 2003, deductibles among small firms increased 100 percent in PPO plans when employees use in-network providers and 131 percent when they use out-of-network providers; among large firms, deductibles in PPO plans increased 33 percent and 44 percent, respectively. And in 2003, 40.3 percent of employees in the smallest firms contributed 41 percent or more of the total family premium, compared with only 11.2 percent of employees in large firms. Clearly, fundamental change in the small employer market is necessary, including new options for helping small firms gain access to the advantages large firms have in purchasing health benefits.

Nuclear Mass Predictions within the Skyrme HFB Theory

NASA Astrophysics Data System (ADS)

Samyn, M.; Goriely, S.; Pearson, J. M.

2005-05-01

To increase the reliability of predictions of highly neutron-rich nuclear masses we systematically analyze the sensitivity of Hartree-Fock-Bogoliubov (HFB) mass formulae to various physical inputs, such as a density dependence of the pairing interaction, a low effective mass, the particle-number projection, the symmetry energy, … We typically use a 10-parameter Skyrme force and a 4-parameter δ-function pairing force. The 14 degrees of freedom are adjusted to the masses of all measured nuclei with N,Z ⩾ 8 given in the 2001 and 2003 Audi et al. compilations. The masses of light and proton-rich nuclei are corrected by a 4-parameter phenomenological Wigner term. With more than ten such parameter sets complete mass tables are constructed, going from one drip line to the other, up to Z = 120.

An initial investigation on the challenges of managing construction workforce in Saudi Arabia

NASA Astrophysics Data System (ADS)

Al-Emad, N.; Rahman, I. A.

2017-11-01

Most of the construction workers in Saudi Arabia are foreigners from several countries having different knowledge, skills and cultures. These create challenges to administer the workers in ensuring project success. This paper presents an initial investigation to uncover the challenges faced by construction professionals in managing construction workforce in Saudi Arabia. It describes insight processes of handling the workforce during planning stage, recruitment procedures and construction stage based on interview with senior manager who are well experienced in handling mega construction projects in Saudi Arabia. The interview was carried out in semi structured mode where the interviewee was given ample time to express the experiences encountered in dealing the workforce issue. This preliminary work able to identify among important issues related to construction workers are restrictions to non-Muslim skilled workers, limited visa quota, being away from family, delay in salary payment, cheating of workers skill’s status, safety issues, communication barriers and living conditions. Hence, these issues require quality leadership attributes such as continuous empathy with workers, respectful, trustful, sincere, reliable, good communication skills and problem solving skills. These findings are useful to construction practitioners and also research work related to construction leadership in handling worker’s issues.

Change in career aspirations and job values from study time to working life.

2007-05-01

The main aim of this paper is to uncover whether the actual career choices and job values of newly qualified nurses are in accordance with the predictions they made at the commencement of their nursing education. A cohort of Norwegian nurse students was followed from the beginning of their education in 1998 through nursing school and 2,years after graduating. Questionnaire data from 221 nursing students at three points in time: 1998, 2001 and 2003 were analysed with frequency distributions and paired samples t-tests. For 140 respondents data from all three points were available. Initially motives like human contact, helping others, job security were important, and 92% had a wish for further education. Career preferences were often midwifery, public heath and nursing practice in high tech areas. Towards the end of the bachelor course (2001), there was more ambiguity in the helping motives. On one hand, the students wanted to be altruistic but on the other hand, they wanted gratitude in return when giving help to patients. Seventy five per cent of the students had plans for further education within a period of about 2 years after graduation. Midwifery, public health work and high tech practice were still preferred. Findings from 2003 indicated only 16% had started or finished further education 2 years after graduation. When appraising future job challenges in 2001 and 2003, there is a decrease in emphasis on the values human contact and part-time work and an increase in emphasis on high salary and job security. During the student period, the bachelor programme was regarded as a basis for further education, but 2 years after graduation only 16% had realized further education. Preferences related to job values regarding a prospective job reveal a decrease in the importance of human contact and an increase in the importance of a high salary and job security from 2001 to 2003.

Drawing on the results of a national survey of 1,907 firms with three or more workers, this paper reports on several facets of job-based health insurance, including the cost to employers and workers; plan offerings and enrollments; patient cost sharing and benefits; eligibility, coverage, and take-up rates; and results from questions about employers' knowledge of market trends and health policy initiatives. Premiums increased 11 percent from spring 2000 to spring 2001, and the percentage of Americans in health maintenance organizations (HMOs) fell six percentage points to its lowest level since 1993, while preferred provider organization (PPO) enrollment rose to 48 percent. Despite premium increases, the percentage of firms offering coverage remained statistically unchanged, and a relatively strong labor market has continued to shield workers from the higher cost of coverage.

Bakke, B; Ulvestad, B; Stewart, P; Eduard, W

2004-01-01

Aims: To study the relation between lung function decrease and cumulative exposure to dust and gases in tunnel construction workers. Methods: A total of 651 male construction workers (drill and blast workers, tunnel concrete workers, shotcreting operators, and tunnel boring machine workers) were followed up by spirometric measurements in 1989–2002 for an average of six years. Outdoor concrete workers, foremen, and engineers served as a low exposed referent population. Results: The between worker component of variability was considerably reduced within the job groups compared to the whole population, suggesting that the workers within job groups had similar exposure levels. The annual decrease in FEV1 in low-exposed non-smoking workers was 21 ml and 24 ml in low-exposed ever smokers. The annual decrease in FEV1 in tunnel construction workers was 20–31 ml higher than the low exposed workers depending on job group for both non-smokers and ever smokers. After adjustment for age and observation time, cumulative exposure to nitrogen dioxide showed the strongest association with a decrease in FEV1 in both non-smokers, and ever smokers. Conclusion: Cumulative exposure to nitrogen dioxide appeared to be a major risk factor for lung function decreases in these tunnel construction workers, although other agents may have contributed to the observed effect. Contact with blasting fumes should be avoided, diesel exhaust emissions should be reduced, and respiratory devices should be used to protect workers against dust and nitrogen dioxide exposure.

2018-01-01

The shortage in Hong Kong of construction workers is expected to worsen in future due to the aging population and increasing construction activity. Construction work is dangerous and to help reduce the premature loss of construction workers due to work-related disabilities, this study measured the work ability of 420 Hong Kong construction workers with a Work Ability Index (WAI) which can be used to predict present and future work performance. Given the importance of WAI, in this study the effects of individual and work-related factors on WAI were examined to develop and validate a WAI model to predict how individual and work-related factors affect work ability. The findings will be useful for formulating a pragmatic intervention program to improve the work ability of construction workers and keep them in the work force. PMID:29758018

Advances in river ice hydrology 1999-2003

Morse, Brian; Hicks, Faye

2005-01-01

In the period 1999 to 2003, river ice has continued to have important socio-economic impacts in Canada and other Nordic countries. Concurrently, there have been many important advances in all areas of Canadian research into river ice engineering and hydrology. For example: (1) River ice processes were highlighted in two special journal issues (Canadian Journal of Civil Engineering in 2003 and Hydrological Processes in 2002) and at five conferences (Canadian Committee on River Ice Processes and the Environment in 1999, 2001 and 2003, and International Association of Hydraulic Research in 2000 and 2002). (2) A number of workers have clearly advanced our understanding of river ice processes by bringing together disparate information in comprehensive review articles. (3) There have been significant advances in river ice modelling. For example, both one-dimensional (e.g. RIVICE, RIVJAM, ICEJAM, HEC-RAS, etc.) and two-dimensional (2-D; www.river2d.ca) public-domain ice-jam models are now available. Work is ongoing to improve RIVER2D, and a commercial 2-D ice-process model is being developed. (4) The 1999-2003 period is notable for the number of distinctly hydrological and ecological studies. On the quantitative side, many are making efforts to determine streamflow during the winter period. On the ecological side, some new publications have addressed the link to water quality (temperature, dissolved oxygen, nutrients and pollutants), and others have dealt with sediment transport and geomorphology (particularly as it relates to break-up), stream ecology (plants, food cycle, etc.) and fish habitat.There is the growing recognition, that these types of study require collaborative efforts. In our view, the main areas requiring further work are: (1) to interface geomorphological and habitat models with quantitative river ice hydrodynamic models; (2) to develop a manager's toolbox (database management, remote sensing, forecasting, intervention methodologies, etc.) to enable agencies to intervene better at the time of ice-jam-induced floods; and (3) finalize ice-jam prevention methods on the St Lawrence River to safeguard its $2 billion commercial navigation industry.

Workplace mortality and severe injury are disproportionately distributed among foreign born and Hispanic construction workers. Worker Centers (WCs) provide services and advocacy for low-wage workers and a way for investigators to reach them. The goal of this project is to prevent occupational injuries by increasing awareness of hazards and self-efficacy among foreign born, Hispanic construction workers and by expanding the agenda of WCs to include occupational health and safety (H&S). Investigators partnered with eight WCs in seven cities to train worker leaders to deliver a modified OSHA 10-hr curriculum to their peers. Thirty-two worker leaders trained 446 workers over 3 years. There was a demonstrated improvement in knowledge, hazard identification, self-efficacy, and sustainable H&S activities. This study provides evidence for successful implementation of a training intervention for low wage, low literacy Hispanic construction workers using a community-based participatory research approach.

Soft tissue musculoskeletal injuries make up a high proportion of all work-related injuries in construction. Data from Workers' Compensation claims indicate that strains and sprains are the leading compensable injury for construction workers. This study describes the consequences of soft tissue musculoskeletal injuries for construction workers, and assesses the persistence of symptoms after an injury and the impact of that injury on return to work. Through an Emergency Department surveillance system [Hunting et al., 1994a], we recorded 176 construction worker visits, from 5/01/93 through 2/28/95, for strains, sprains, joint injury or pain, tendinitis, dislocations, hernias, or other musculoskeletal injuries excluding fractures. Telephone interviews were conducted several months after workers had visited the emergency room for a musculoskeletal injury. Seventy individuals were interviewed about the long-term impacts of 72 incidents that had resulted in work-related musculoskeletal injuries. For 46 (62%) of the 74 diagnoses, problems continued beyond two months. The likelihood of problems continuing more than two months varied considerably by body location of injury. Hispanic workers and older workers were more likely to have continuing symptoms. Eleven of the 45 construction workers with symptoms persisting longer than two months were not employed at the time of the interview. Only 11 of the 45 workers with ongoing symptoms told us that modifications had been made to their jobs to accommodate their symptoms. About one-quarter of these 45 subjects reported substantial effects on home or work life. Acute musculoskeletal injuries in construction workers frequently result in chronic symptoms, and those with chronic symptoms report substantial effects of the injury on their quality of life. Job accommodations were made in a minority of these injuries. These findings point to the need for heightened efforts for injury prevention in this industry. Copyright 1999 Wiley-Liss, Inc.

Decadal-scale changes of pesticides in ground water of the United States, 1993-2003.

2008-01-01

Pesticide data for ground water sampled across the United States between 1993-1995 and 2001-2003 by the U.S. Geological Survey National Water-Quality Assessment Program were evaluated for trends in detection frequency and concentration. The data analysis evaluated samples collected from a total of 362 wells located in 12 local well networks characterizing shallow ground water in agricultural areas and six local well networks characterizing the drinking water resource in areas of variable land use. Each well network was sampled once during 1993-1995 and once during 2001-2003. The networks provide an overview of conditions across a wide range of hydrogeologic settings and in major agricultural areas that vary in dominant crop type and pesticide use. Of about 80 pesticide compounds analyzed, only six compounds were detected in ground water from at least 10 wells during both sampling events. These compounds were the triazine herbicides atrazine, simazine, and prometon; the acetanilide herbicide metolachlor; the urea herbicide tebuthiuron; and an atrazine degradate, deethylatrazine (DEA). Observed concentrations of these compounds generally were < 0.12 microg L(-1). At individual wells, changes in concentrations typically were < 0.02 microg L(-1). Data analysis incorporated adjustments for changes in laboratory recovery as assessed through laboratory spikes. In wells yielding detectable concentrations of atrazine, DEA, and prometon, concentrations were significantly lower (alpha = 0.1) in 2001-2003 than in 1993-1995, whereas detection frequency of these compounds did not change significantly. Trends in atrazine concentrations at shallow wells in agricultural areas were found to be consistent overall with recent atrazine use data.

Construction workers have intensive contact with their workplace and are possibly susceptible to Nutritional and Food Insecurity. This paper assessed the Food Security status, diet and anthropometric measures of workers in the Construction Industry living in the city of João Pessoa, PB. This cross-sectional study included 59 workers housed at construction sites. The workers were given the Brazilian Scale for Measuring Food Insecurity and Nutrition, had anthropometric measures taken and completed the Diet Quality Index, comparing their eating at the construction site and at home. Statistical analyses described the mean, standard deviation, frequency and Pearson correlations. Food Insecurity was reported by 71.2% of the workers, and 69.5% were overweight. The mean values of the Healthy Eating Index suggested that the workers' diets were in need of modification. There were statistically significant inverse associations among the Healthy Eating Index and Body Mass Index, waist circumference, percentage of total fat and cholesterol. Values obtained using the Scale showed Food Insecurity coupled with high excess weight and dietary inadequacies, revealing that these workers are at risk for health problems.

Problem Segments within the retail industry have a substantially higher rate of work-related fatality due to workplace violence compared to the retail industry overall. Certain demographic subgroups may be at higher risk. Method National traumatic injury surveillance data were analyzed to characterize the distribution of fatality rates due to workplace violence among selected retail workers in the United States from 2003 through 2008. Results Overall, the highest fatality rates due to work-related homicide occurred among men, workers aged ≥ 65 years, black, Asian, foreign-born and Southern workers. Among foreign-born workers, those aged 16–24 years, non-Hispanic whites and Asians experienced substantially higher fatality rates compared to their native-born counterparts. Conclusions The burden of work-related homicide in the retail industry falls more heavily on several demographic groups, including racial minorities and the foreign-born. Further research should examine the causes of these trends. Interventions designed to prevent workplace violence should target these groups. PMID:23398701

Work-related injuries are the most important cause of work absence, disability, retirement, mutilation, and even mortality. In Iran a great number of work-related injuries are occurred in construction industry. However, less than 12% of total workers are active in the construction sector. This study aimed to determine the incidence rate of work-related injuries, the type of injuries, and its other determinants among the construction workers of Ilam (Iran). The participants were the workers and staffs working in the construction activities of Ilam in Western Iran. All the recorded injuries and deaths related to the construction workers of Ilam from 2006-2009 were collected from the Bureau of Labor and Social Affairs and then analyzed by the statistical package of SPSS (version 19, for Windows). During 2006 - 2009 in Ilam, 387workers encountered the building accidents. Their mean age was 34.3 years (SD = 12.4). The average annual incidence of work-related injuries among the workers was 8.2 per 1000 workers. Fracture with 275 cases (71%) was the most common outcome of injuries, and slipping and falling with 77 cases (36%) were the most important events and exposures. The most important factor related to injuries was the lack of surveillance by employers which was also related with the severity of accident-induced injuries (P < 0.004). Considering the effectiveness of the relevant preventive measures activities such as training the workers as well as using safety tools and more surveillance by employers can decrease the number of work-related injuries among constructive workers.

Tuberculosis incidence in New York City (NYC) declined between 1992 and 2000 from 51.1 to 16.6 cases per 100,000 population. In January 2001, universal real-time genotyping of TB cases was implemented in NYC. Isolates from culture-confirmed tuberculosis cases from 2001 to 2003 were genotyped using IS6110 and spoligotype to describe the extent and factors associated with genotype clustering after declining TB incidence. Of 2408 (91.8%) genotyped case isolates, 873 (36.2%) had a pattern indistinguishable from that of another study period case, forming 212 clusters; 248 (28.4%) of the clustered cases had strains believed to have been widely transmitted during the epidemic years in the early 1990s in NYC. An estimated 27.4% (873 minus 212) of the 2408 cases were due to recent infection that progressed to active disease during the study period. Younger age, birth in the United States, homelessness, substance abuse and presence of TB symptoms were independently associated with greater odds of clustering.

Background: While smoking is the major cause of chronic obstructive pulmonary disease (COPD), occupational exposures to vapors, gases, dusts, and fumes (VGDF) increase COPD risk. This case-control study estimated the risk of COPD attributable to occupational exposures among construction workers. Methods: The study population included 834 cases and 1243 controls participating in a national medical screening program for older construction workers between 1997 and 2013. Qualitative exposure indices were developed based on lifetime work and exposure histories. Results: Approximately 18% (95%CI=2–24%) of COPD risk can be attributed to construction-related exposures, which are additive to the risk contributed by smoking. Amore » measure of all VGDF exposures combined was a strong predictor of COPD risk. Conclusions: Construction workers are at increased risk of COPD as a result of broad and complex effects of many exposures acting independently or interactively.

Construction sector is one of the highest risk industries contributing to the development of work-related musculoskeletal disorders. In general construction activities involve the composition of various construction trades, such as painting, plastering, concreting, paving and bricklaying. Different construction trades workers are exposed to risk factors depending their job and task. There are risk factors associated with the construction trade workers activities such as concrete work, brickwork, piling work excavation works and etc. Thus, the aim of this research is to document the critical activities that affect the musculoskeletal disorders amongst Malaysian construction trade workers, in particular to the bricklayers. The objective of this research is to identify the critical activities that affect to the musculoskeletal disorder among the bricklayers. The data for this research was collected via observation to the construction workers for the specific trades which are bricklayers in Perak. Finding of this research is by identifying the critical activities involved that affect the musculoskeletal disorder suffering among bricklayers.

Objective The penalty point system was introduced in Italy in June 2003. The aim of this study was to evaluate the health effects of this legislation in the Lazio region. Methods Poisson models were used to compare emergency department visits, hospitalizations and death between the pre‐law and post‐law periods (July 2001–June 2003; July 2003–June 2004). Results The emergency department visit rate ratio (RR) of the two periods was 0.87 (95% confidence interval (CI) 0.86 to 0.88); the corresponding hospital admission RR was 0.87 (95% CI 0.84 to 0.9). The death RR was 0.93 (95% CI 0.82 to 1.05). Conclusion After the legislation was introduced, there were fewer visits to the emergency department, hospitalizations and death from road traffic injuries. However, the effect was lower than expected, and it decreased over time. PMID:17296692

If non-baryonic dark matter exists in the form of neutralinos, a neutrino flux is expected from the decay of neutralino pair annihilation products inside heavy celestial bodies. Data taken with the AMANDA-II neutrino telescope located at the South Pole, have been used in a search for this indirect dark matter signal. Results will be presented from searches for neutralinos accumulated in the Sun, using AMANDA-II data of 2001 and 2003, and in the centre of the Earth, using AMANDA-II data of 2001 to 2003. Future perspectives, achieved by higher statistics data samples acquired during recent years and by the combinedmore » AMANDA-IceCube detector, will also be discussed.« less

Exposure assessment in health assessments for hand-arm vibration syndrome.

PubMed

Mason, H J; Poole, K; Young, C

2011-08-01

Assessing past cumulative vibration exposure is part of assessing the risk of hand-arm vibration syndrome (HAVS) in workers exposed to hand-arm vibration and invariably forms part of a medical assessment of such workers. To investigate the strength of relationships between the presence and severity of HAVS and different cumulative exposure metrics obtained from a self-reporting questionnaire. Cumulative exposure metrics were constructed from a tool-based questionnaire applied in a group of HAVS referrals and workplace field studies. These metrics included simple years of vibration exposure, cumulative total hours of all tool use and differing combinations of acceleration magnitudes for specific tools and their daily use, including the current frequency-weighting method contained in ISO 5349-1:2001. Use of simple years of exposure is a weak predictor of HAVS or its increasing severity. The calculation of cumulative hours across all vibrating tools used is a more powerful predictor. More complex calculations based on involving likely acceleration data for specific classes of tools, either frequency weighted or not, did not offer a clear further advantage in this dataset. This may be due to the uncertainty associated with workers' recall of their past tool usage or the variability between tools in the magnitude of their vibration emission. Assessing years of exposure or 'latency' in a worker should be replaced by cumulative hours of tool use. This can be readily obtained using a tool-pictogram-based self-reporting questionnaire and a simple spreadsheet calculation.

To help making comfortable workplaces and to prevent health disorders induced by the exposure to moderate cold in two different groups of out-door workers, we conducted a survey to compare subjective symptoms and cold prevention measures in winter between traffic control workers and construction workers. The subjects of this study were 98 male traffic control workers and 149 male workers engaged in building construction. Work loads of traffic control workers and construction workers were estimated at RMR1-2 and RMR2-4, respectively. All subjects were asked to complete a self-administered questionnaire covering age, occupational career, working figure, present illness, past history of diseases, individual preventive measures to the cold, subjective symptoms in the winter (43 items) and subjective symptoms occurred during daytime working in the winter (6 items). In two parts of the construction workplaces (the place where a morning assembly was held and on the 7th floor of the construction site) dry bulb, wet bulb and globe temperatures were measured in January. Windchill Index (kcal/cm,(2) x h) was calculated by the measured dry bulb temperature and wind velocity. Mean values of dry bulb temperature between 9:00 and 16:30 in the place where a morning assembly was held for three days were between 4.8 +/- 1.2 degrees C at 9:00 am and 9.3 +/- 1.1 degrees C at noon. Mean values of Windchill Index in the place where a morning assembly was held were between 490.8+/-23.9 kcal/cm(2) x h at 9:30 am and 608.2+/-47.3 kcal/cm(2) x h at 2:30 pm. Occupational career, monthly working days, daily working hours, one way commuting hours, and daily smoking numbers of the traffic control workers were significantly shorter than the construction workers (p<0.01). There were no significant differences in the prevalence of chillness in the arms and legs between the traffic control workers (5.1%) and the construction workers (0.7%). Prevalence of wearing a warm underwear, body warmer, warm trousers, underpants, warm socks, shoe warmer and muffler in the traffic control workers were significantly higher than the construction workers. The subjective symptoms in winter complained most frequently were shoulder stiffness (51.0%), finger cold sensation (50.0%) and neck stiffness (48.0%) in the traffic control workers, and were easy to get fatigued (49.0%), lumbago (48.3%) and finger cold sensation (47.7%) in the construction workers. On the basis of the results obtained, it is clearly shown that the two groups are at the risk of disorders due to their working environment. Therefore, these workers are needed to undergo occupational health programs for prevention of cold exposure disorders. Applications of preventive countermeasures for both groups are discussed.

The purposes of this study were a) to summarize measurements of airborne (respirable) crystalline silica dust exposure levels among U.S. workers, b) to provide an update of the 1990 Stewart and Rice report on airborne silica exposure levels in high-risk industries and occupations with data for the time period 1988–2003, c) to estimate the number of workers potentially exposed to silica in industries that the Occupational Safety and Health Administration (OSHA) inspected for high exposure levels, and d) to conduct time trend analyses on airborne silica dust exposure levels for time-weighted average (TWA) measurements. Compliance inspection data that were taken from the OSHA Integrated Management Information System (IMIS) for 1988–2003 (n = 7,209) were used to measure the airborne crystalline silica dust exposure levels among U.S. workers. A second-order autoregressive model was applied to assess the change in the mean silica exposure measurements over time. The overall geometric mean of silica exposure levels for 8-hr personal TWA samples collected during programmed inspections was 0.077 mg/m3, well above the applicable American Conference of Governmental Industrial Hygienists threshold limit value of 0.05 mg/m3. Surgical appliances supplies industry [Standard Industrial Classification (SIC) 3842] had the lowest geometric mean silica exposure level of 0.017 mg/m3, compared with the highest level, 0.166 mg/m3, for the metal valves and pipe fitting industry (SIC 3494), for an 8-hr TWA measurement. Although a downward trend in the airborne silica exposure levels was observed during 1988–2003, the results showed that 3.6% of the sampled workers were exposed above the OSHA-calculated permissible exposure limit.

Despite scientific evidence linking workers' fatigue to occupational safety (due to impaired physical or cognitive function), little is known about this relationship in construction workers. To assess the association between construction workers' reported fatigue and their perceived difficulties with physical and cognitive functions. Using data from a convenience sample of US construction workers participating in the 2010-11 National Health Interview Survey two multivariate weighted logistic regression models were built to predict difficulty with physical and with cognitive functions associated with workers' reported fatigue, while controlling for age, smoking status, alcohol consumption status, sleep hygiene, psychological distress and arthritis status. Of 606 construction workers surveyed, 49% reported being 'tired some days' in the past 3 months and 10% reported 'tired most days or every day'. Compared with those feeling 'never tired', workers who felt 'tired some days' were significantly more likely to report difficulty with physical function (adjusted odds ratio [AOR] = 2.03; 95% confidence interval [CI] 1.17-3.51) and cognitive function (AOR = 2.27; 95% CI 1.06-4.88) after controlling for potential confounders. Our results suggest an association between reported fatigue and experiencing difficulties with physical and cognitive functions in construction workers. © The Author 2015.

Violent deaths of media workers associated with conflict in Iraq, 2003-2012.

PubMed

Collinson, Lucie; Wilson, Nick; Thomson, George

2014-01-01

Background. The violent deaths of media workers is a critical issue worldwide, especially in areas of political and social instability. Such deaths can be a particular concern as they may undermine the development and functioning of an open and democratic society. Method. Data on the violent deaths of media workers in Iraq for ten years (2003-2012) were systematically collated from five international databases. Analyses included time trends, weapons involved, nationality of the deceased, outcome for perpetrators and location of death. Results. During this ten-year period, there were 199 violent deaths of media workers in Iraq. The annual number increased substantially after the invasion in 2003 (peaking at n = 47 in 2007) and then declined (n = 5 in 2012). The peak years (2006-2007) for these deaths matched the peak years for estimated violent deaths among civilians. Most of the media worker deaths (85%) were Iraqi nationals. Some were killed whilst on assignment in the field (39%) and 28% involved a preceding threat. Common perpetrators of the violence were: political groups (45%), and coalition forces (9%), but the source of the violence was often unknown (29%). None of the perpetrators have subsequently been prosecuted (as of April 2014). For each violent death of a media worker, an average of 3.1 other people were also killed in the same attack (range 0-100 other deaths). Discussion. This analysis highlights the high number of homicides of media workers in Iraq in this conflict period, in addition to the apparently total level of impunity. One of the potential solutions may be establishing a functioning legal system that apprehends offenders and puts them on trial. The relatively high quality of data on violent deaths in this occupational group, suggests that it could act as one sentinel population within a broader surveillance system of societal violence in conflict zones.

Occupational fatalities due to electrocutions in the construction industry.

PubMed

Janicak, Christopher A

2008-01-01

Occupational fatalities due to contact with electricity account for approximately 9% of all deaths in the construction industry and is the fourth leading cause of death in this industry. Differences in the proportions of electrocutions in the construction industry are significantly different from other industries based upon the age of the worker and the source of the electricity. This study found that, in the construction industry, the proportion of occupational fatalities due to contact with electric current is significantly higher for workers in the 16 to 19 years old age group. Contact with overhead power lines occurred more frequently with younger workers, while contact with electric wiring, transformers, and related equipment was found to occur more frequently with older workers. The proportion of fatalities due to this event was also found to account for a significantly greater proportion of fatalities in the construction industry overall. The proportions of electrocution fatalities in the construction industry were found to be significantly higher for younger workers when compared to all other industries. Focusing prevention measures toward younger workers who work near overhead power lines could have a significant impact upon death rates. For older workers, the focus should be on those who work on or near transformers, electrical wiring, and components. Across the construction industry, implementation of effective lockout-tagout programs, and verification of energy isolation, can prevent approximately 125 fatalities per year in the construction industry.

The parser doesn't ignore intransitivity, after all

PubMed Central

Staub, Adrian

2015-01-01

Several previous studies (Adams, Clifton, & Mitchell, 1998; Mitchell, 1987; van Gompel & Pickering, 2001) have explored the question of whether the parser initially analyzes a noun phrase that follows an intransitive verb as the verb's direct object. Three eyetracking experiments examined this issue in more detail. Experiment 1 strongly replicated the finding (van Gompel & Pickering, 2001) that readers experience difficulty on this noun phrase in normal reading, and found that this difficulty occurs even with a class of intransitive verbs for which a direct object is categorically prohibited. Experiment 2, however, demonstrated that this effect is not due to syntactic misanalysis, but is instead due to disruption that occurs when a comma is absent at a subordinate clause/main clause boundary. Exploring a different construction, Experiment 3 replicated the finding (Pickering & Traxler, 2003; Traxler & Pickering, 1996) that when a noun phrase “filler” is an implausible direct object for an optionally transitive relative clause verb, processing difficulty results; however, there was no evidence for such difficulty when the relative clause verb was strictly intransitive. Taken together, the three experiments undermine the support for the claim that the parser initially ignores a verb's subcategorization restrictions. PMID:17470005

Hearing loss among older construction workers: Updated analyses.

A prior study of this construction worker population found significant noise-associated hearing loss. This follow-up study included a much larger study population and consideration of additional risk factors. Data included audiometry, clinical chemistry, personal history, and work history. Qualitative exposure metrics for noise and solvents were developed. Analyses compared construction workers to an internal reference group with lower exposures and an external worker population with low noise exposure. Among participants (n = 19 127) an overall prevalence of hearing loss of 58% was observed, with significantly increased prevalence across all construction trades. Construction workers had significantly increased risk of hearing loss compared to reference populations, with increasing risk by work duration. Noise exposure, solvent exposure, hypertension, and smoking were significant risk factors in multivariate models. Results support a causal relationship between construction trades work and hearing loss. Prevention should focus on reducing exposure to noise, solvents, and cigarette smoke. © 2018 Wiley Periodicals, Inc.

Exploring Subsurface Geology Using Radar Techniques: Experiments in Sahara and Consequences for Mars Exploration

2004-05-01

For several years, we have conducted a quantitative study of radar penetration performances in various desert arid environments. This study combines both SAR (Synthetic Aperture Radar) imaging from orbital and airborne platforms and in situ GPR (Ground Penetrating Radar) measurements. Laboratory characterization of various minerals and rocks are used as input to electromagnetic models such as IEM (Integral Equation Model) and FDTD (Finite Difference Time Domain) that describe the subsurface scattering process for inversion purposes. Several test sites were explored, mainly the Sahara. Our first experiment was realized in Republic of Djibouti, an arid volcanic area which is a good analog to Mars. We observed a very little radar penetration there because of the presence of iron oxides and salts in the subsurface that make the soil conductive [Paillou et al., GRL, 2001]. A more favorable site for radar penetration was then explored in southern Egypt: the Bir Safsaf area where buried river channels were discovered using orbital SAR images. We showed how to combine SAR and GPR in order to obtain a complete description of subsurface geology down to several meters [Paillou et al., IEEE TGRS, 2003]. Such field experiments were the basis for more systematic laboratory measurements of the electromagnetic properties of various rocks and minerals which were used in numerical models in order to simulate the performances of future Martian radars, e.g. MARSIS and NETLANDER low frequency radars [Heggy et al., Icarus, 2001; Berthelier et al., JGR, 2003; Heggy et al., JGR, 2003]. More recently, new explorations were conducted in Mauritania in order to demonstrate radar capacities for geologic mapping [Grandjean et al., Coll. Afr. Geol., 2004] and in Libya where radar discovered a double impact crater in the southern desert [Paillou et al., C.R. Geoscience, 2003]. More local radar experiments were also conducted on a test site located in France, the Pyla sand dune, where we observed and modeled a radar signature of subsurface water [Grandjean et al., IEEE TGRS, 2001; Paillou et al., IGARSS'03, 2003]. All of these results shall be used in the context of "terrestrial analogs to Mars" studies in order to prepare for future Mars exploration using radars [Farr et al., Planet. Dec. Study, 2002; Paillou et al., 35th LPSC, 2004]: it concerns both GPR instruments onboard rovers and landers devoted to the exploration of the deep subsurface [Berthelier at al., ESA Pasteur, 2003] and SAR imaging systems onboard orbital platforms for global mapping of the shallow subsurface geology [Paillou et al., Conf. Water Mars, 2001].

Destruction of a Holothuria scabra population by overfishing at Abu Rhamada Island in the Red Sea.

Hasan, Mohamed Hamza

2005-10-01

Populations of Holothuria scabra at Abu Rhamada Island were investigated during 52 months, from July 1999 to October 2003. During the first 23 months (July, 1999-May, 2001) the Island had a robust population with a tri-modal size frequency distribution curve, very high densities (85.7-95.1 ind./100 m2 at the sandy habitat), high abundance (3362-3110 individuals) and biomass (46.7-34.3 kg/100 m2). Also, during this period most individuals were at depths between 4 and 6m and no individuals were recorded deeper than 15m. The population declined after harvesting began (June, 2001) and by March, 2002 the size frequency distribution showed a bimodal pattern with an obvious decrease in abundance of large individuals. There was also a slight reduction in densities (73.2-60.1 ind./100 m2 at the sandy habitat), abundance (2292-1682 individuals) and biomass (21.6-11.3 kg/100 m2), and a marked shift towards deeper waters. Overfishing reached its maximum during the final 19 months of the study, and by October, 2003, density (30.7-0.4 ind./100 m2 at the sandy habitat), abundance (802-10 individuals) and biomass (6.9-0.1 kg/100 m2) were all greatly reduced. The size frequency distribution of the population became unimodal, large animals disappeared and no recruits were seen. During this period, individuals were found at very deep depths (30 to >40 m). The study also showed that sandy substrate was the preferred habitat for H. scabra, accommodating the largest number of individuals. The population of H. scabra at Abu Rhamada Island was found to spawn biannually from 1999 to 2001, then only once during 2002 when high fishing pressure occurred, and ceased completely in 2003. The sex ratio was not significantly different from 1:1 before fishing begun, but shifted to an increasing male bias reaching 93% males by January 2003. None of the small animals remaining after January, 2003 could be sexed. Size at sexual maturity decreased from prefishing (185 mm for females and 160 mm for males) to 155 mm for females and 125 mm for males in January 2003. There was a positive relationship between fecundity and size. And oocyte/female was highest in 1999 (0.73-1.7 million) and 2000 (0.75-1.72 million), decreased during 2001 (0.2-0.85 million) to reach its minimum at 2002 (0.28-0.29 million).

In this article, we explored 1) the extent of mental health (MH) service use by American Red Cross disaster relief workers, both before (lifetime) and 1 year after the September 11, 2001 terrorist attacks, and 2) demographic, disaster and MH variables predicting (1-year) post-September 11 MH service use in this population. A sample of 3015 Red Cross disaster workers was surveyed 1 year after the attacks, regarding demographic characteristics, MH service use before and since the attacks, and posttraumatic stress disorder (PTSD) symptoms. Findings revealed that while 13.5% used MH services before the attacks, 10.7% used services after. Variables increasing the likelihood of MH service use after the attacks included the following: no previous MH treatment, younger age, being divorced/widowed, and higher PTSD intrusion or hyperarousal symptoms. Findings support other recent research on MH service use after the September 11 attacks.

Increasing heat waves-particularly in urban areas where construction is most prevalent, highlight a need for heat exposure assessment of construction workers. This study aims to characterize the effects of heat on construction workers from a site in Gandhinagar. This study involved a mixed methods approach consisting of a cross sectional survey with anthropometric measurements (n = 219) and four focus groups with construction workers, as well as environmental measurements of heat stress exposure at a construction site. Survey data was collected in two seasons i.e., summer and winter months, and heat illness and symptoms were compared between the two time periods. Thematic coding of focus group data was used to identify vulnerability factors and coping mechanisms of the workers. Heat stress, recorded using a wet bulb globe temperature monitor, was compared to international safety standards. The survey findings suggest that heat-related symptoms increased in summer; 59% of all reports in summer were positive for symptoms (from Mild to Severe) as compared to 41% in winter. Focus groups revealed four dominant themes: (1) Non-occupational stressors compound work stressors; (2) workers were particularly attuned to the impact of heat on their health; (3) workers were aware of heat-related preventive measures; and (4) few resources were currently available to protect workers from heat stress. Working conditions often exceed international heat stress safety thresholds. Female workers and new employees might be at increased risk of illness or injury. This study suggests significant health impacts on construction workers from heat stress exposure in the workplace, showed that heat stress levels were higher than those prescribed by international standards and highlights the need for revision of work practices, increased protective measures, and possible development of indigenous work safety standards for heat exposure.

Toward Establishing the Validity of the Resource Interpreter's Self-Efficacy Instrument

NASA Astrophysics Data System (ADS)

Smith, Grant D.

Interpretive rangers serve as one of the major educational resources that visitors may encounter during their visit to a park or other natural area, yet our understanding of their professional growth remains limited. This study helps address this issue by developing an instrument that evaluates the beliefs of resource interpreters regarding their capabilities of communicating with the public. The resulting 11-item instrument was built around the construct of Albert Bandura's self-efficacy theory (Bandura, 1977, 1986, 1997), used guidelines and principles developed over the course of 30 years of teacher efficacy studies (Bandura, 2006; Gibson & Dembo, 1984; Riggs & Enochs, 1990; Tschannen-Moran & Hoy, 2001; Tschannen-Moran, Hoy, & Hoy, 1998), and probed areas of challenge that are unique to the demands of resource interpretation (Brochu & Merriman, 2002; Ham, 1992; Knudson, Cable, & Beck, 2003; Larsen, 2003; Tilden, 1977). A voluntary convenience sample of 364 National Park Service rangers was collected in order to conduct the statistical analyses needed to winnow the draft instrument down from 47 items in its original form to 11 items in its final state. Statistical analyses used in this process included item-total correlation, index of discrimination, exploratory factor analysis, and confirmatory factor analysis.

To examine trends in the proportion of work-related emergency department visits not expected to be paid by workers' compensation during 2003-2006, and to identify demographic and clinical correlates of such visits. A total of 3,881 work-related emergency department visit records drawn from the 2003-2006 National Hospital Ambulatory Medical Care Surveys. Secondary, cross-sectional analyses of work-related emergency department visit data were performed. Odds ratios and 95 percent confidence intervals were modeled using logistic regression. A substantial and increasing proportion of work-related emergency department visits in the United States were not expected to be paid by workers' compensation. Private insurance, Medicaid, Medicare, and workers themselves were expected to pay for 40 percent of the work-related emergency department visits with this percentage increasing annually. Work-related visits by blacks, in the South, to for-profit hospitals and for work-related illnesses were all more likely not to be paid by workers' compensation. Emergency department-based surveillance and research that determine work-relatedness on the basis of expected payment by workers' compensation systematically underestimate the occurrence of occupational illness and injury. This has important methodological and policy implications. © Health Research and Educational Trust.

Enhancing the competitiveness of skilled construction workers through collaborative education and training

Professionalism of construction workers is one of the keys to the success of infrastructure development projects. The professionalism of the workforce is demonstrated through the possession of expertise competence certificate (SKA) and/or certificates of skills (SKT) issued formally through competency tests by the National Construction Cervices Development Agency (LPJKN). The magnitude of the national skilled manpower needs has not been able to meet the availability of professional workforce. Strategies to develop the quality of resources require sufficient information on the characteristics of the resources themselves, facilities, constraints, stakeholder support, regulations, and socioeconomic as well as cultural conditions. The problems faced by Indonesia in improving the competitiveness of skilled construction workers are (1) how the level of professionalism of skill workers in construction field, (2) what the constrains on improving the quality of skilled construction workers,and(3) how the appropriate model of education and training skillfull construction work. The study was designed with quantitative and qualitative approaches. Quantitative methods were used to describe the profile of sklill constructions worker. Qualitative methods were used toidentify constraintsin improving the qualityof skilled labor, as well as formulate a viable collaborative education and training model for improving the quality of skill labor. Data were collected by documentation, observation, and interview. The result of the study indicate theat (1) the professionalism knowledge of skilled constructions worker are in still low condition, (2) the constrain faced in developing the quality of skilled construction labor cover economic and structural constrains, and (3) collaborative eduction and training model can improve the quality ods skilld labor contructions.

Seasonal evolution of the Martian cryptic region: influence of the atmospheric opacity

NASA Astrophysics Data System (ADS)

Portyankina, G.; Markiewicz, W. J.; Kossacki, K. J.

2005-08-01

Mars Orbiter Camera (MOC) performed repeated observations of chosen areas in polar regions to monitor seasonal and/or annual changes. Images E09-00028 and R08-01730 centered at 82.5°S, 41°E were taken in years 2001 and 2003 respectively. They show the same morphological features, however differ significantly in surface albedo, the image from 2001 shows a lower albedo than the one from 2003. Imaged areas lie inside the cryptic region and show spider patterns. The observed interannual variability may be related to the global dust storm that happened in 2001 and finished around Ls=230°, i.e. just before image E09-00028 was taken. Here we model the seasonal ice sublimation/condensation cycle to show that the evolution of this particular area of the cryptic region was affected by the dust storm during year 2001. The model used for the present work has been described in Kossacki and Markiewicz, (2004). It includes self-consistent treatment of the sublimation and condensation of CO2 and H2O ices, and was used to calculate surface temperatures and thicknesses of CO2 and H2O ice layers for the corresponding conditions of these two years. Our modelling shows that the dust storm lowered surface temperatures, and thus caused later than usual seasonal sublimation of both CO2 and water ices. It also considerably decreased surface albedo and these two important effects almost cancel: the solar flux is reduced during a dust storm but at the same time the dust that precipitates onto the surface reduces the albedo and thus allows a bigger fraction of the solar radiation to be absorbed. The surface temperature stays at about 146K for almost half of the Martian year, both during 2001 and 2003. We also considered impact of the surface roughness: it results in some smoothing of the average temperature rise that is associated with the defrosting of the surface.

Construction is a manual, heavy, and complex sector concerning the most fatal accidents and high incidence of occupational illnesses and injuries resulting in days away from work. In Hong Kong, "Pilot Medical Examination Scheme for Construction Workers" was launched in 2014 to detect the health problems of their construction workforce. All registered workers under the Construction Workers Registration Board are eligible to join the scheme. The purpose of this paper is to assess the physical condition, physiological status, and musculoskeletal disorders of 942 construction workers in Hong Kong. This study adopted a two-phase design, which includes a basic medical examination to measure the workers' physiological parameters, such as blood pressure, resting heart rate, glucose, cholesterol, uric acid, liver function test, and renal function test; as well as a face-to-face interview following the medical examination to collect their demographic information and pain experience. Individual characteristics, including gender, age, obesity, alcohol drinking habit, and sleeping habit influenced the health condition of construction workers. Among the participants, 36.1% and 6.5% of them were overweight and obese, respectively. In addition, 43.0%, 38.4%, 16.2%, and 13.9% of the participants exceeded the thresholds of cholesterol, blood pressure, urea nitrogen, and uric urea, correspondingly. Moreover, 41.0% of the participants suffered musculoskeletal pain, where the most frequent painful parts occur in the lower back, shoulder, knees, leg, and neck. Through these findings, a series of important issues that need to be addressed is pointed out in terms of maintaining the physical well-being and reducing musculoskeletal disorders of construction workers. The finding may have implications for formulating proper intervention strategies for the sustainable development of Hong Kong's construction industry.

The average annual growth rate of real gross domestic product (GDP) from the third quarter of 2001 through the second quarter of 2003 in the United States was about 2.6 percent. GDP growth rates in the third and fourth quarters of 2003 were about 8 percent and 4 percent, respectively. The upward trends in many sectors of the U.S. economy in 2003, however, were shared by few of the mineral materials industries. Annual output declined in most nonfuel mining and mineral processing industries, although there was an upward turn toward yearend as prices began to increase.

The informal workers phenomenon on housing construction projects in Indonesia is different from workers in other sectors who would always request as permanent employees. Substantively, the informal workers are disinclined to be bound as permanent employees which different from the general labor paradigm. Hence, the objective of this study is to find out how the labour selection process, the factors that affected their performance, and the suitable wage system to achieve the target completion of housing construction project. The qualitative method is used to uncover and understand the meaning behind the phenomena (numina) of informal workers action and their influence on housing construction project which called phenomenological approach. Five informal workers and two project managers were selected as informants based on predetermined criteria with in-depth interviews. The results showed that the informal worker were more satisfied with the wage based on unit price while working in the housing construction project for the flexibility in working hours. In addition, the developer was also relieved because they only control the quality and the achievement of the project completion time which supported by informal worker leader. Therefore, these findings are beneficial for both of developer and government as policy maker to succeed the housing program in Indonesia.

Injury surveillance in construction: eye injuries.

PubMed

Welch, L S; Hunting, K L; Mawudeku, A

2001-07-01

Occupational eye injuries are both common and preventable. About 20% of occupational eye injuries occur in construction. To investigate the nature of eye injuries among construction workers, we analyzed a large data set of construction worker injuries. In addition, we interviewed 62 workers with eye injuries to further explore circumstances of eye injury and workers' attitudes and behavior toward the use of eye protection. Eleven percent (363 cases) of the 3,390 construction workers in our data set were treated for eye injuries. Welders, plumbers, insulators, painters/glaziers, supervisors, and electricians had a higher proportion of all injuries due to eye injuries than other trades. Nearly half of the diagnoses were abrasions (46%) followed by foreign objects or splash in the eye (29%), conjunctivitis (10%), and burns (5%). In the interviews with 62 workers, we found that employers very frequently required eye protection for all tasks or for high-risk tasks, and workers report wearing eye protection regularly. However, most did not wear eye protection with top and side shields; if we believe the injuries occurred because a particle or liquid passed between the glasses and the workers' faces, increased use of goggles or full shields would have prevented two-thirds of this group of injuries.

Schoonover, Todd; Bonauto, David; Silverstein, Barbara; Adams, Darrin; Clark, Randy

2010-06-01

This study compares construction industry groups in Washington State by injury severity and cost, and ranks industry groups according to potential for prevention. All Washington State workers' compensation compensable claims with date of injury between 2003 and 2007 were classified into North American Industrial Classification System (NAICS) industry groups. Claims were then aggregated by injury type and industry groups were ranked according to a prevention index (PI). The PI is the average of the rank orders of the claim count and the claim incidence rate. A lower PI indicates a higher need for prevention activities. The severity rate was calculated as the number of days of time loss per 10,000 full-time equivalents (FTEs). For all injury types, construction industry groups occupy 7 of the top 15 PI ranks in Washington State. The severity rate among construction industry groups was twice that for non-construction groups for all injury types. Foundation, structure, and building exterior contractors (NAICS 2381) ranked highest in prevention potential and severity among construction industry groups for most common injury types including falls from elevation, fall on same level, struck by/against, and musculo-skeletal disorders of the neck, back, and upper extremity (WMSDs). Median claim costs by injury type were generally higher among construction industry groups. The construction industry in Washington State has a high severity rate and potential for prevention. The methods used for characterizing these industry groups can be adapted for comparison within and between other industries and states. These data can be used by industry groups and employers to identify higher cost and higher severity injury types. Knowledge about the relative frequencies and costs associated with different injury types will help employers and construction industry associations make better informed decisions about where prevention efforts are most needed and may have the greatest impact. The results of this study can also be used by industry stakeholders to cooperatively focus on high cost and high severity injuries and explore best practices, interventions, and solutions as demonstrated by efforts to prevent musculoskeletal disorders in masonry (Entzel, Albers, & Welch, 2007). Initiating construction industry groups to focus on high cost and high severity injuries may also help prevent other types of injuries. (c) 2010 National Safety Council. Published by Elsevier Ltd.

Given a shortage of construction workers, it is important to develop strategies to avoid early retirement caused by cardiovascular diseases in Hong Kong. (1) to describe the cardiovascular health of construction workers in Hong Kong, (2) to examine the demographic differences in cardiovascular health, and (3) to examine the association between health behaviors and cardiovascular health factors. 626 registered construction workers were included in the analysis. Blood chemistry, blood pressure, weight, and height were measured. Face-to-face questionnaire interviews for health behaviors were conducted. Approximately two-thirds of the construction workers achieved only three out of the seven “ideal” cardiovascular health metrics. The younger, more educated, and female subjects had better cardiovascular health scores than the older, less educated, and male counterparts. Fish and seafood consumption was associated with (1) ideal weight status and (2) ideal cholesterol level, whereas less soft drink consumption was associated with ideal cholesterol level. The findings highlighted the importance of promoting cardiovascular health in the construction industry. This study provided some insights for future interventions, which should include increasing fish and seafood intake, decreasing soft drink consumption, and enhancing the health literacy amongst older, less educated, and male construction workers.

With regard to metabolic syndrome-related risks (MS risks), obese workers have been the focus of attention, and less attention has been paid to non-obese subjects as if they were free from the risks. The present analysis was initiated to know if no-obesity means no-MS risks. Participants of the study were 804 male workers, who showed no pathological findings in 12 MS-related and other health parameters in 2003, and had complete sets of data in 2008. They were classified by BMI in 2003 into lean (< 18.5), normal (> or = 18.5 to < 25) and obese groups (> or =25). Proportion of MS in 2008 was examined by use of the second phase of MS criteria. Proportions for the lean, normal and obese subjects who met MS criteria in 2008 were 3.2, 4.8 and 5.3%, respectively, with no significant difference in proportions among them. In the non-obese (i.e., lean+normal) group, age was not significantly influential to increase BMI. Thus, the MS risk exists even in non-obese young workers. Anti-MS effort should be directed not only to obese but to non-obese workers, and care should be extended irrespective of ages.

This paper presents an exploratory study conducted in Makkah city to uncover issues faced by construction workers from the construction leaders’ perspective. Eleven construction leaders/experts were interviewed to unleash their experiences on handling the foreign workers working in Makkah construction projects. Most of the experts are senior management staffs with more than 10 years’ working experience in Saudi Arabia construction industry. The interviews were carried out in semi structured mode where all the information was captured manually and also electronically. The identified issues were sorted based on its commonality into 10 clusters. Hence in each cluster, the numbers of issue considered by the experts are reflecting the importance of that particular cluster. The result of the clusters according to the number of issues mentioned by the experts are safety issues, restricted government regulation, demotivated issues, lack of quality workers, poor living quality, communication barriers, adaption issues, poor attitudes, lack of logistical arrangements and lack of education. With these identified issues it will assist the construction players in the construction industry of Saudi Arabia in dealing with their workers.

Workplace violence in long haul trucking: occupational health nursing update.

PubMed

Anderson, Debra Gay

2004-01-01

Almost 2 million workdays and millions of dollars are lost annually because of non-fatal assaults suffered at the workplace (NIOSH, 1996). Twenty workers, on average, are murdered each week in the United States and an estimated 18,000 workers per week are victims of non-fatal assault (NIOSH, 2001). Violence and stress are two interrelated issues that affect the work force. In-depth studies of these issues have not been conducted with long haul truckers in general, or with women in non-traditional, male dominated fields such as the long haul trucking industry. Epidemiological data related to violence and stress experienced by these under-studied populations are needed to plan effective interventions to reduce occupational risks. Studies employing both qualitative and quantitative methods are needed to articulate risk and protective factors related to violence against workers (Runyan, 2001). Occupational health nurses are qualified to participate in the development and implementation of research and intervention studies to improve worker safety related to violence at the workplace for men and women in both traditional and non-traditional occupational roles.

The Worker Component At The World Trade Center Cleanup: Addressing Cultural And Language Differences In Emergency Operations

DOE Office of Scientific and Technical Information (OSTI.GOV)

McCabe, B.; Carpenter, C.; Blair. D.

On September 11, 2001, the terrorist attacks on the World Trade Center (WTC) caused astronomical loss of life and property. Systems in place to manage disaster response were strained to the limit because key first responders were among the casualties when the twin towers collapsed. In addition, the evolution of events required immediate response in a rapidly changing and extremely hazardous situation. Rescue, recovery, and clean up became an overpowering and sustained effort that would utilize the resources of federal, state and local governments and agencies. One issue during the response to the WTC disaster site that did not receivemore » much attention was that of the limited and non-English speaking worker. The Operating Engineers National HAZMAT Program (OENHP), with its history of a Hispanic Outreach Program, was acutely aware of this issue with the Hispanic worker. The Hispanic population comprises approximately 27% of the population of New York City (1). The extremely unfortunate and tragic events of that day provided an opportunity to not only provide assistance for the Hispanic workers, but also to apply lessons learned and conduct studies on worker training with language barriers in a real life environment. However, due to the circumstances surrounding this tragedy, the study of these issues was conducted primarily by observation. Through partnerships with other organizations such as the Occupational Safety and Health Administration (OSHA), the New York Health Department, the New York Department of Design and Construction (DDC), the New York Committee for Occupational Safety and Health (NYCOSH), and private companies such as 3M and MSA, OENHP was able to provide translated information on hazards, protective measures, fit testing of respirators, and site specific safety and health training. The OENHP translated materials on hazards and how to protect workers into Spanish to assist in getting the information to the limited and non- English speaking workers.« less

CDC began abortion surveillance in 1969 to document the number and characteristics of women obtaining legal induced abortions. This report summarizes and describes data voluntarily reported to CDC regarding legal induced abortions obtained in the United States in 2003. For each year since 1969, CDC has compiled abortion data by state or area of occurrence. During 1973-1997, data were received from or estimated for 52 reporting areas in the United States: 50 states, the District of Columbia, and New York City. In 1998 and 1999, CDC compiled abortion data from 48 reporting areas. Alaska, California, New Hampshire, and Oklahoma did not report, and data for these states were not estimated. During 2000-2002, Oklahoma again reported these data, increasing the number of reporting areas to 49, and for 2003, Alaska again reported and West Virginia did not, maintaining the number of reporting areas at 49. A total of 848,163 legal induced abortions were reported to CDC for 2003 from 49 reporting areas, representing a 0.7% decline from the 854,122 legal induced abortions reported by 49 reporting areas for 2002. The abortion ratio, defined as the number of abortions per 1,000 live births, was 241 in 2003, a decrease from the 246 in 2002. The abortion rate was 16 per 1,000 women aged 15-44 years for 2003, the same as for 2002. For the same 47 reporting areas, the abortion rate remained relatively constant during 1998-2003. During 2001-2002 (the most recent years for which data are available), 15 women died as a result of complications from known legal induced abortion. One death was associated with known illegal abortion. The highest percentages of reported abortions were for women who were unmarried (82%), white (55%), and aged <25 years (51%). Of all abortions for which gestational age was reported, 61% were performed at < or =8 weeks' gestation and 88% at <13 weeks. From 1992 (when detailed data regarding early abortions were first collected) through 2002, steady increases have occurred in the percentage of abortions performed at < or =6 weeks' gestation, with a slight decline in 2003. A limited number of abortions were obtained at >15 weeks' gestation, including 4.2% at 16--20 weeks and 1.4% at > or =21 weeks. A total of 36 reporting areas submitted data documenting that they performed and enumerated medical (nonsurgical) procedures, making up 8.0% of all known reported procedures from the 45 areas with adequate reporting on type of procedure. During 1990-1997, the number of legal induced abortions gradually declined. When the same 47 reporting areas are compared, the number of abortions decreased during 1996-2001, then slightly increased in 2002 and again decreased in 2003. In 2000 and 2001, even with one additional reporting state, the number of abortions declined slightly, with a minimal increase in 2002 and a further decrease in 2003. In 2001 and 2002, as in the previous years, deaths related to legal induced abortions occurred rarely. Abortion surveillance in the United States continues to provide the data necessary for examining trends in numbers and characteristics of women who obtain legal induced abortions and to increase understanding of this pregnancy outcome. Policymakers and program planners use these data to improve the health and well-being of women and infants.

To analyze severe acute occupational poisoning accidents related to organic solvents reported in China between 1989 and 2003, and to study the characteristics of severe acute occupational poisoning accidents and provide scientific evidences for prevention and control strategies. The data from the national occupational poisoning case reporting system were analyzed with descriptive methods. (1) There were 58 severe acute occupational poisoning accidents related to organic solvents for 15 years with 393 workers poisoned and 48 workers died. The total poisoning rate was 51.2%, and the total mortality was 12.2%. The average poisoning age was (30.9 +/- 8.8) years old and the average death age was (30.6 +/- 12.0) years old. (2) There were 11 types of chemicals that caused these poisoning accidents, and most of the accidents were caused by benzene and homologs. (3) Most of the accidents occurred in manufacture, chemical industry, construction industry, transportation and storage industry, service and commerce. The risk was higher in some jobs than in others, such as paint spraying and cleanout. The poisoning accidents occurred more frequently from April to July each year. (4) The main causes of the accidents were poor ventilation (23.6%), lack of personal protection equipment (21.2%), lack of safety education (19.2%), and lack of safety work practice (15.8%) etc. The ventilation at the workplace involved in organic solvents should be maintained and the skin contacting directly with the organic solvents should be avoided, and it is encouraged to replace the poison with the nontoxic or lower toxic chemicals.

Study Design The survey of small businesses was undertaken as part of a project testing the response of employers to offers of subsidized coverage. Employers were asked whether they offered insurance, and about the insurance status of their employees. The merged February–March 2001 CPS was used to identify the employment status, firm size, and employer-offering status for uninsured persons in the U.S. Data Collection Telephone interviews with small businesses in San Diego County. Principal Findings Only 21 percent of the uninsured in the U.S. are full-time employees (or their dependents) in small businesses (<100 employees) that do not offer insurance. The employment status of the uninsured is heterogeneous: many work for large employers, small employers who do offer insurance, or are self-employed, part-time workers, or have no workers in the household. Although there are many small businesses in San Diego that do not offer coverage, most of them have very few uninsured workers. Over 50 percent of businesses that do not offer coverage have either zero or one uninsured worker. There are very few small businesses that do not offer coverage and that have substantial numbers of uninsured workers. These businesses are not quite as rare as a needle in a haystack, but they are very difficult to find. Conclusions If all small businesses that do not offer insurance now could be persuaded to start offering coverage, and if all the full-time workers (and their dependents) in those businesses accepted insurance, the number of uninsured would decline by 21 percent—a significant decline, but leaving 80 percent of the problem untouched. If the prime target for programs of subsidized insurance are small businesses that do not offer coverage now and that have substantial numbers of uninsured workers, the target is very small.

The 2001/2002 and 2002/2003 breeding seasons of New Zealand sea lions (NZSLs) on the Auckland Islands were marked by a high pup mortality caused by acute bacterial infections. As part of a health survey from 1998/1999 to 2004/2005, tissues and swabs of lesions had been collected at necropsy to identify the bacteria associated with pup mortality. Klebsiella pneumoniae was grown in pure culture from 83% of various organs and lesions in 2001/2002 and 76% in 2002/2003, and less frequently in the following seasons (56% in 2003/2004 and 49% in 2004/2005). Pup isolates of K. pneumoniae showed identical minimal inhibitory concentrations (MIC) of cefuroxime, neomycin, cephalotin, cephalexin and dihydrostreptomycin, suggesting clonal aetiology of the pathogen. Isolates also tested negative for production of extended-spectrum beta-lactamases (ESBLs), which was not in favour of an anthropogenetic origin of the epidemic strain. Pulsed-field gel electrophoresis (PFGE) of XbaI DNA macrorestriction fragments was performed on isolates of K. pneumoniae and Klebsiella oxytoca from 35 pups, thee NZSL adult females, and from three human patients for comparison. PFGE showed that pup isolates of K. pneumoniae were genetically indistinguishable but were neither related to K. pneumoniae from humans and from NZSL adults, nor to K. oxytoca from NZSLs. It is concluded that the 2001/2002 and 2002/2003 epidemics at Sandy Bay rookery were caused by a single K. pneumoniae clonal lineage, genetically different from the strain carried by adult NZSLs. An anthropogenic origin of the K. pneumoniae clone could not be confirmed, but further investigations are required to rule-out such occurrence.

Decadal-scale changes of pesticides in ground water of the United States, 1993-2003

Pesticide data for ground water sampled across the United States between 1993-1995 and 2001-2003 by the U.S. Geological Survey National Water-Quality Assessment Program were evaluated for trends in detection frequency and concentration. The data analysis evaluated samples collected from a total of 362 wells located in 12 local well networks characterizing shallow ground water in agricultural areas and six local well networks characterizing the drinking water resource in areas of variable land use. Each well network was sampled once during 1993-1995 and once during 2001-2003. The networks provide an overview of conditions across a wide range of hydrogeologic settings and in major agricultural areas that vary in dominant crop type and pesticide use. Of about 80 pesticide compounds analyzed, only six compounds were detected in ground water from at least 10 wells during both sampling events. These compounds were the triazine herbicides atrazine, simazine, and prometon; the acetanilide herbicide metolachlor; the urea herbicide tebuthiuron; and an atrazine degradate, deethylatrazine (DEA). Observed concentrations of these compounds generally were <0.12 ??g L-1. At individual wells, changes in concentrations typically were <0.02 ??g L-1. Data analysis incorporated adjustments for changes in laboratory recovery as assessed through laboratory spikes. In wells yielding detectable concentrations of atrazine, DEA, and prometon, concentrations were significantly lower (?? = 0.1) in 2001-2003 than in 1993-1995, whereas detection frequency of these compounds did not change significantly. Trends in atrazine concentrations at shallow wells in agricultural areas were found to be consistent overall with recent atrazine use data.

To increase the reliability of predictions of highly neutron-rich nuclear masses we systematically analyze the sensitivity of Hartree-Fock-Bogoliubov (HFB) mass formulae to various physical inputs, such as a density dependence of the pairing interaction, a low effective mass, the particle-number projection, the symmetry energy, ... We typically use a 10-parameter Skyrme force and a 4-parameter {delta}-function pairing force. The 14 degrees of freedom are adjusted to the masses of all measured nuclei with N,Z {>=} 8 given in the 2001 and 2003 Audi et al. compilations. The masses of light and proton-rich nuclei are corrected by a 4-parameter phenomenological Wignermore » term. With more than ten such parameter sets complete mass tables are constructed, going from one drip line to the other, up to Z = 120.« less

[Increased risk of chronic obstructive pulmonary disease among tunnel construction workers].

PubMed

Ulvestad, Bente; Lund, May Brit

2003-08-28

As tunnel workers are exposed to particles from drilling, blasting and diesel exhaust, we aimed to assess the occurrence of respiratory symptoms and lung function decline in underground construction workers and relate these findings to exposure. 212 tunnel workers and a reference group of 205 outdoor construction workers participated in a cross-sectional study. Respiratory symptoms and lung function were studied in relation to exposure. A subgroup of 29 non-smoking concrete workers who had been exposed to tunnel environment for one year, were examined by acoustic rhinometry, exhaled NO, spirometry and a questionnaire. Finally 122 tunnel workers were included in a prospective study in 1991 and re-examined in 1999. Among the tunnel workers the prevalence of chronic obstructive pulmonary disease (COPD) was 14% vs. 8% in the reference subjects. Compared to the reference subjects, the tunnel workers had a significant decrease in FEV1, related to years of exposure. Concrete workers from the tunnel site had significantly increased exhaled NO levels and nasal mucosal swelling compared to subjects who had performed similar tasks outdoors. The decrease in FEV1 was associated with cumulative exposure to respirable dust and quartz. Inhalation of construction-generated dust and gases enhances the risk of chronic obstructive pulmonary disease in tunnel workers.

The main aim of this study was to investigate the personal exposure to diesel and petrol exhaust fumes in occupations when exposure is prevalent and/or high. We also investigated the correlation between the five particle fractions [particles with an aerodynamic diameter <1 microm (PM(1)), particles with an aerodynamic diameter <2.5 microm (PM(2.5)), particles in size 0.1-10 microm, elemental carbon (EC) and total carbon (TC)] and nitrogen dioxide (NO(2)), in the various occupational environments. Seventy-one workers were included in the study. They were subdivided into seven groups depending on working area, working indoors, out of doors or in vehicles and type of exposure (diesel or petrol exhaust). Personal measurements were performed during 3 days per worker. We used five indicators of the particle fraction: PM(1), PM(2.5), particle measured with a real-time monitoring instrument for particles in sizes 0.1 and 10 microm (DataRAM), EC and TC. We used NO(2) as an indicator of the gas phase. Tunnel construction workers showed the highest levels of exposure for all indicators, followed by diesel-exposed garage workers. For the other five groups, the levels were statistically significantly lower, and the differences between the groups were small. The full-shift geometric average of PM(1) varied between 119 microg m(-3) (tunnel construction workers) and 11 microg m(-3) (taxi drivers). For PM(2.5), the levels varied between 231 microg m(-3) (tunnel construction workers) and 16 microg m(-3) (bus and lorry drivers). For the measurements with the real-time monitoring instrument DataRAM, the levels varied between 398 microg m(-3) (tunnel construction workers) and 14 microg m(-3) (taxi drivers). For EC, the levels varied between 87 microg m(-3) (tunnel construction workers) and 4 microg m(-3) (other outdoor workers exposed to diesel exhaust), and for TC, the levels varied between 191 microg m(-3) (tunnel construction workers) and 10 microg m(-3) (taxi drivers). Finally, for NO(2), the levels varied between 350 microg m(-3) (tunnel construction workers) and 32 microg m(-3) (other outdoor workers exposed to diesel exhaust). For the indoor workers exposed to diesel exhaust fumes only, all the indicators correlated comparatively well and statistically significantly to each other (r(2) = 0.44-0.89). For the other groups, correlations were lower and showed no consistent pattern. The tunnel construction workers had exposure levels for all indicator substances that were considerably and significantly higher than for the other groups. The NO(2) levels were higher for indoor workers exposed to diesel exhaust than for all other groups (except tunnel construction workers). All particle fractions, as well as NO(2) correlated well in occupations with indoor exposure to diesel exhaust.

To develop a fatigue assessment scale and test its reliability and validity for commercial construction workers. Using a two-phased approach, we first identified items (first phase) for the development of a Fatigue Assessment Scale for Construction Workers (FASCW) through review of existing scales in the scientific literature, key informant interviews (n = 11) and focus groups (three groups with six workers each) with construction workers. The second phase included assessment for the reliability, validity, and sensitivity of the new scale using a repeated-measures study design with a convenience sample of construction workers (n = 144). Phase one resulted in a 16-item preliminary scale that after factor analysis yielded a final 10-item scale with two sub-scales ("Lethargy" and "Bodily Ailment"). During phase two, the FASCW and its subscales demonstrated satisfactory internal consistency (alpha coefficients were FASCW [0.91], Lethargy [0.86] and Bodily Ailment [0.84]) and acceptable test-retest reliability (Pearson Correlations Coefficients: 0.59-0.68; Intraclass Correlation Coefficients: 0.74-0.80). Correlation analysis substantiated concurrent and convergent validity. A discriminant analysis demonstrated that the FASCW differentiated between groups with arthritis status and different work hours. The 10-item FASCW with good reliability and validity is an effective tool for assessing the severity of fatigue among construction workers. © 2015 Wiley Periodicals, Inc.

A qualitative investigation of Hispanic construction worker perspectives on factors impacting worksite safety and risk

PubMed Central

2011-01-01

Background Hispanic workers have higher rates of injury and death on construction worksites than workers of other ethnicities. Language barriers and cultural differences have been hypothesized as reasons behind the disparate rates. Methods We conducted two series of focus groups with union and non-union Hispanic construction workers to ask them about their perceptions of the causes for the unequal rates. Spanish transcripts were translated and coded in QSR NVivo software for common themes. Results Workers reported a difficult work environment characterized by supervisor pressure, competition for jobs and intimidation with regard to raising safety concerns. Language barriers or cultural factors were not strongly represented as causative factors behind the rates. Conclusion The results of this study have informed the development of an intervention trial that seeks to prevent falls and silica dust exposure by training contractors employing Hispanic construction workers in the elements of safety leadership, including building respect for their Hispanic workers and facilitating their participation in a safety program.

Migration and Health in the Construction Industry: Culturally Centering Voices of Bangladeshi Workers in Singapore.

PubMed

Dutta, Mohan J

2017-01-29

Construction workers globally face disproportionate threats to health and wellbeing, constituted by the nature of the work they perform. The workplace fatalities and lost-time injuries experienced by construction workers are significantly greater than in other forms of work. This paper draws on the culture-centered approach (CCA) to dialogically articulate meanings of workplace risks and injuries, voiced by Bangladeshi migrant construction workers in Singapore. The narratives voiced by the participants suggest an ecological approach to workplace injuries in the construction industries, attending to food insecurity, lack of sleep, transportation, etc. as contextual features of work that shape the risks experienced at work. Moreover, participant voices point to the barriers in communication, lack of understanding, and experiences of incivility as features of work that constitute the ways in which they experience injury risks. The overarching discourses of productivity and efficiency constitute a broader climate of threats to worker safety and health.

2012-10-01

There are few data about safety in the construction industry in Palestine. The main aim of the study was to assess worker's experiences and perceptions of safety at construction sites in Hebron and Bethlehem governorates of the West Bank. A structured questionnaire was completed through direct interviews with 349 construction workers. Of the respondents, 34.6% had experienced work-related accidents, 13.0% and 65.6% indicated that their workplace did not have a first-aid kit or trained first-aid specialist respectively, 35.8% reported that their work sites did not have safety tools and 83.7% had not received safety training. Workers perceived that awareness and training were the most frequent factor affecting workers' safety, with the foreman position having the greatest impact on the workers' safety. Greater enforcement of the current Palestinian safety laws is needed.

Objectives We aimed to investigate how mental distress was associated with pain and injuries in a convenience sample of construction workers. Methods A cross-sectional, mental health assessment was conducted in a convenience sample of construction workers (N=172). A subsample participated in a clinical interview (N=10). We used a cut-off (≥1.50) on HSCL-25 to determine substantial mental distress and determined associations with pain and injury outcomes. Results The prevalence of substantial mental distress was 16 % in the workers. This was supported by follow-up clinical interviews where nine out of ten workers fulfilled the criteria for a mental disorder. Substantial mental distress was associated with both injury rate and self-reported pain. Conclusion This pilot study strongly suggests the need for rigorous studies on construction worker mental health, and how it affects their work and wellbeing. PMID:24064778

Assessing Heat Stress and Health among Construction Workers in a Changing Climate: A Review

PubMed Central

Acharya, Payel; Boggess, Bethany

2018-01-01

Construction workers are at an elevated risk of heat stress, due to the strenuous nature of the work, high temperature work condition, and a changing climate. An increasing number of workers are at risk, as the industry’s growth has been fueled by high demand and vast numbers of immigrant workers entering into the U.S., the Middle East and Asia to meet the demand. The risk of heat-related illnesses is increased by the fact that little to no regulations are present and/or enforced to protect these workers. This review recognizes the issues by summarizing epidemiological studies both in the U.S. and internationally. These studies have assessed the severity with which construction workers are affected by heat stress, risk factors and co-morbidities associated with heat-related illnesses in the construction industry, vulnerable populations, and efforts in implementing preventive measures.

Health benefits offer rates: is there a nonresponse bias?

PubMed

Pickreign, Jeremy D; Gabel, Jon R

2005-04-01

To determine whether a nonresponse bias exists in the offer rate for health benefits in firms with fewer than 50 workers and to present a simple adjustment to correct for observed bias. The 2003 Employer Health Benefits Survey (EHBS) conducted by the Kaiser Family Foundation and Health Research and Educational Trust, and a follow-up survey of nonrespondents to the 2003 EHBS. We conducted a follow-up survey to the 2003 EHBS to collect health benefits offering data from firms with fewer than 50 workers. We used McNemar's test to verify that the follow-up survey provided results comparable to the EHBS, and t-tests were used to determine nonresponse bias. We applied a simple weighting adjustment to the EHBS. The data for both the EHBS and the follow-up survey were collected by the same survey research firm. The EHBS interviews the person most knowledgeable about the firm's health benefits, while the follow-up survey interviews the first person who answers the telephone whether they are the most knowledgeable or not. Principal Findings. Firms with 3-9 workers were more likely to exhibit a bias than were firms with 10-24 workers and 25-49 workers. Although the calculated bias for each size category was not significant, there is sufficient evidence to warrant caution when reporting offer rates. Survey nonresponse in the EHBS produces an upward bias on estimates for the offer rates of small firms. Although not significant, this upward bias is because of nonresponse by small firms that do not offer health benefits. Our research is limited in that we only control for differences in the size of the firm.

2014-01-01

Early retirement is an increasing problem in the construction industry. There is limited information about causes leading employees to leave working life early. We have compared construction workers present situation with their perception of future demands at work to avoid early retirement. All 87 employees in a medium-sized Norwegian construction company participated in the study. All were men and answered questionnaires on health and pain, work ability, mechanical exposure, psychosocial conditions, and demands regarding future working conditions. Most workers showed good work ability, irrespective of age. Many reported high levels of mechanical exposure at work. The level of musculoskeletal pain was higher in the middle-aged (30-50 year old) age groups and seniors aged over 50 years than among the youngest workers less than 30 years of age. All workers reported that good health was important for continued working. Most workers stated that future work must not be too physically demanding. Many workers reported relatively low job satisfaction; consequently an interesting job was rated as important for continuing work. Good social conditions were a high priority. According to the examined construction workers, good health and reduced levels of mechanical exposure at work are essential to avoid early retirement.

Substance abuse is a serious problem, because it affects both workers and young people. Prevalence and consequences of cannabis abuse among construction workers in particular are not well studied in Egypt. To determine the association between non-fatal occupational injuries among construction workers and their demographic and occupational factors and to assess the frequency of cannabis abuse and its relationship to injury severity and workdays lost. A case-control study was conducted at Mansoura Emergency Hospital. Cases were 100 acutely injured male workers. A control group of 90 healthy age-matched workers was selected from 8 construction sites. Workers were interviewed, and a questionnaire was completed that included socio-demographic data, full occupational history, and causes and type of injury. Injury outcome measures included lost workdays and the injury severity score (ISS). Cannabis abuse in injured workers was monitored by preliminary testing of urine and confirmatory testing of blood. Logistic regression analysis revealed that the independent predictors of occupational injuries were rural residence, being a carpenter or painter and past history of injuries. The most common accidents were slipping falls (62%). Confirmed cannabis test was positive in 51.1% of the injured workers. Median days away from work were greater among cannabis users than non-users. The ISS was significantly higher among users compared to non-users ( p < 0.05). Cannabis abuse can increase injury severity and prolong workdays lost. Drug testing is recommended for at-risk construction workers with inadequate safety measures.

Objective Highly pathogenic avian influenza A(H5N1) is endemic in poultry in Viet Nam. The country has experienced the third highest number of human infections with influenza A(H5N1) in the world. A study in Hanoi in 2001, before the epizootic that was identified in 2003, found influenza A(H5N1) specific antibodies in 4% of poultry market workers (PMWs). We conducted a seroprevalence survey to determine the seroprevalence of antibodies to influenza A(H5N1) among PMWs in Hanoi, Thaibinh and Thanhhoa provinces. Methods We selected PMWs from five markets, interviewed them and collected blood samples. These were then tested using a horse haemagglutination inhibition assay and a microneutralization assay with all three clades of influenza A(H5N1) viruses that have circulated in Viet Nam since 2004. Results The overall seroprevalence was 6.1% (95% confidence interval: 4.6–8.3). The highest proportion (7.2%) was found in PMWs in Hanoi, and the majority of seropositive subjects (70.3%) were slaughterers or sellers of poultry. Discussion The continued circulation and evolution of influenza A(H5N1) requires comprehensive surveillance of both human and animal sites throughout the country with follow-up studies on PMWs to estimate the risk of avian–human transmission of influenza A(H5N1) in Viet Nam.

A job exposure matrix may be useful for the study of biomechanical workplace risk factors when individual-level exposure data are unavailable. We used job title–based exposure data from a public data source to construct a job exposure matrix and test exposure-response relationships with prevalent carpal tunnel syndrome (CTS). Exposures of repetitive motion and force from the Occupational Information Network were assigned to 3,452 active workers from several industries, enrolled between 2001 and 2008 from 6 studies. Repetitive motion and force exposures were combined into high/high, high/low, and low/low exposure groupings in each of 4 multivariable logistic regression models, adjusted for personal factors. Although force measures alone were not independent predictors of CTS in these data, strong associations between combined physical exposures of force and repetition and CTS were observed in all models. Consistent with previous literature, this report shows that workers with high force/high repetition jobs had the highest prevalence of CTS (odds ratio = 2.14–2.95) followed by intermediate values (odds ratio = 1.09–2.27) in mixed exposed jobs relative to the lowest exposed workers. This study supports the use of a general population job exposure matrix to estimate workplace physical exposures in epidemiologic studies of musculoskeletal disorders when measures of individual exposures are unavailable.

The 351.1 nm photoelectron spectrum of the cyclopentadienide ion has been measured, which reveals the vibronic structure of the X~ 2E1'' state of the cyclopentadienyl radical. Equation-of-motion ionization potential coupled-cluster (EOMIP-CCSD) calculations have been performed to construct a diabatic model potential of the X~ 2E1'' state, which takes into account linear Jahn-Teller effects along the e2' normal coordinates as well as bilinear Jahn-Teller effects along the e2' and ring-breathing a1' coordinates. A simulation based on this ab initio model potential reproduces the spectrum very well, identifying the vibronic levels with linear Jahn-Teller angular momentum quantum numbers of +/-1/2. The angular distributions of the photoelectrons for these vibronic levels are highly anisotropic with the photon energies used in the measurements. A few additional weak photoelectron peaks are observed when photoelectrons ejected parallel to the laser polarization are examined. These peaks correspond to the vibronic levels for out-of-plane modes in the ground X~ 2E1'' state, which arise due to several pseudo-Jahn-Teller interactions with excited states of the radical and quadratic Jahn-Teller interaction in the X~ 2E1'' state. A variant of the first derivative of the energy for the EOMIP-CCSD method has been utilized to evaluate the strength of these nonadiabatic couplings, which have subsequently been employed to construct the model potential of the X~ 2E1'' state with respect to the out-of-plane normal coordinates. Simulations based on the model potential successfully reproduce the weak features that become conspicuous in the 0° spectrum. The present study of the photoelectron spectrum complements a previous dispersed fluorescence spectroscopic study Miller and co-workers [J. Chem. Phys. 114, 4855 (2001); 4869 (2001) Miller and co-workers [J. Chem. Phys.114, 4869 (2001)] to provide a detailed account of the vibronic structure of X~ 2E1'' cyclopentadienyl. The electron affinity of the cyclopentadienyl radical is determined to be 1.808+/-0.006 eV. This electron affinity and the gas-phase acidity of cyclopentadiene have been combined in a negative ion thermochemical cycle to determine the C-H bond dissociation energy of cyclopentadiene; D0(C5H6,C-H)=81.5+/-1.3 kcal mol-1. The standard enthalpy of formation of the cyclopentadienyl radical has been determined to be ΔfH298(C5H5)=63.2+/-1.4 kcal mol-1.

Safety and ergonomic considerations for an aging workforce in the US construction industry.

Choi, Sang D

2009-01-01

The US construction workforce is aging as millions of baby boomers move toward retirement age. Older workers make a substantial contribution to construction in terms of skills and experience. However, construction is still one of the most physically demanding occupations, hence the health implications for older workers. Descriptions of injuries, illnesses and fatalities among older workers in the US construction industry from recent literature are presented along with the practical health and safety interventions that have been proposed including: ergonomic interventions, wellness programs, worksite housekeeping, training, and safety climate. Understanding the risks and hazards in specific industries could help identify training and intervention requirements to meet the challenges facing aging workers in these occupational groups.

Safety climate involves worker perception about the relative importance where they work and safety climate and has been shown to be a reliable predictor of safety-related outcomes. The primary objective of this study is to investigate ethnic differences in perceived safety climate among construction workers. Surveys (n = 179) that included a 10-item safety climate scale were administered in Athens, Georgia (GA), at local construction sites and home improvement stores during June-August, 2015. The majority of respondents were carpenters or roofers (39%), followed by laborers (22%), painters and dry wall workers (14%), other skilled trades (14%), and supervisors (11%); 32% were Hispanic. Hispanic ethnicity (p < 0.0001), drinking two or more alcoholic beverages per day (p < 0.0001), working for a company that does not provide health insurance (p = 0.0022), and working for a company with fewer than ten employees (p < 0.0001) were significantly associated with lower perceived safety climate scores. The lower perceived safety climate scores among Hispanic workers indicate that the perception of the importance of safety on the job site is lower among Hispanics construction workers than non-Hispanics construction workers.

Injury surveillance in construction: what is an "injury", anyway?

PubMed

Welch, Laura S; Hunting, Katherine

2003-08-01

Over the last decade, there has been a decline in injuries with days away from work in construction, associated with an increase in injuries with restricted work activity only. We abstracted demographics, diagnosis, cause-of-injury, and hospital discharge information for 481 workers from one large construction project treated in an urban Emergency Department (ED). The project safety team provided data on all injuries from this site, including first aid cases. This site had fewer injuries with days away from work than expected from national rates. Two hundred and fifty-six injuries were reported on the OSHA log, and of those 93 entailed days away from work; 1,515 injuries were considered first aid/medical only. We used a sample of the data to estimate that the site classified as "recordable" 128 of the 481 ED-treated injuries from this site (27%). The pattern of injury varies depending on the subset of injuries examined. Lost time injuries, as reported in BLS data, record fewer lacerations and eye injuries, and more strains and sprains. No one surveillance system presents the full spectrum of occupational injury. Tracking all injuries allow early recognition of injury risks, and therefore can lead to more effective prevention.

In recent years, the number of articles in The American Journal of Sports Medicine (AJSM) has risen dramatically, with an increasing emphasis on evidence-based medicine in orthopaedics and sports medicine. Despite the increase in the number of articles published in AJSM over the past decade, the methodological quality of articles in 2011-2013 has improved relative to those in 2001-2003 and 1991-1993. Meta-analysis. All articles published in AJSM during 2011-2013 were reviewed and classified by study design. For each article, the use of pertinent methodologies, such as prospective data collection, randomization, control groups, and blinding, was recorded. The frequency of each article type and the use of evidence-based techniques were compared relative to 1991-1993 and 2001-2003 by use of Pearson χ(2) testing. The number of research articles published in AJSM more than doubled from 402 in 1991-1993 and 423 in 2001-2003 to 953 in 2011-2013. Case reports decreased from 15.2% to 10.6% to 2.1% of articles published over the study period (P < .001). Cadaveric/human studies and meta-analysis/literature review studies increased from 5.7% to 7.1% to 12.4% (P < .001) and from 0.2% to 0.9% to 2.3% (P = .01), respectively. Randomized, prospective clinical trials increased from 2.7% to 5.9% to 7.4% (P = .007). Fewer studies used retrospective compared with prospective data collection (P < .001). More studies tested an explicit hypothesis (P < .001) and used controls (P < .001), randomization (P < .001), and blinding of those assessing outcomes (P < .001). Multi-investigator trials increased (P < .001), as did the proportion of articles citing a funding source (P < .001). Despite a dramatic increase in the number of published articles, the research published in AJSM shifted toward more prospective, randomized, controlled, and blinded designs during 2011-2013 compared with 2001-2003 and 1991-1993, demonstrating a continued improvement in methodological quality. © 2015 The Author(s).

Construction and health care workers have a high prevalence of musculoskeletal disorders, and they are assumed to have physically demanding jobs. Profession- and gender-specific associations between individual capacity and musculoskeletal pain have not been sufficiently investigated. The main aim of this study was to examine the association between individual capacity (maximal oxygen uptake (V̇O 2max ) and handgrip strength) and musculoskeletal pain among construction and health care workers. This cross-sectional study examined 137 construction and health care workers (58 women and 79 men) with a mean age of 41.8 years (standard deviation 12). Aerobic capacity was indirectly assessed by the Åstrand cycle test, and strength was assessed by a handgrip test. Musculoskeletal pain was described by total pain, divided into neck, shoulder, and low back pain, during the last 12 months, and it was dichotomized in below or above 30 days. Logistic regression was used to analyse the associations between V̇O 2max , strength, and musculoskeletal pain in the total study sample and separately for construction and health care workers. Analyses were adjusted for age, gender, body mass index (BMI), and selected mechanical and psychosocial factors. Every second participant (51.8%) reported pain in either neck, shoulders or low back for more than 30 days during the last 12 months. Among the health care workers, a small but significant association was found between a high V̇O 2max , high handgrip strength, and a low level of musculoskeletal pain. No association was found for the construction workers. An association between V̇O 2max, handgrip strength, and musculoskeletal pain was found for health care workers but not for construction workers. These results indicate that activities promoting individual capacity may reduce musculoskeletal pain for health care workers.

Health and safety implications of recruitment payments in migrant construction workers

Background The Middle East construction sector is heavily reliant on a migrant workforce that predominantly originates from South Asia. It is common practice for migrant construction workers to pay a local labour recruiter the equivalent of one or more years’ prospective overseas salary to secure employment, work and travel permits and transportation. The occupational health and safety implications of these financial arrangements remain unexplored. Aims To examine associations between payment to a labour recruiter, perceived general health and worksite accidents among migrant construction workers in the Middle East. Methods A questionnaire was completed by a convenience sample of predominantly Indian migrant construction workers drawn from a large construction project. The relationship between payment and risk of poor health and workplace accidents was assessed using multivariate logistic regression models (crude and adjusted for socio-demographic and occupational factors). Results There were 651 participants. The majority (58%) of migrant construction workers had paid a labour recruiter and ~40% had experienced a worksite accident. Between 3% (labourers) and 9% (foremen) perceived their health to be poor. Labourers and skilled workers who had paid a labour recruiter were significantly more likely to have experienced a worksite accident in the previous 12 months. Skilled workers, but not labourers and foremen, who had paid a labour recruiter were at increased risk of poor health. Conclusions The mechanisms linking labour recruiter payments to adverse safety and health outcomes warrant investigation with a view to developing interventions to erode these links. PMID:24668316

Maintaining adequate working ability of construction workers is of considerable importance for society, as the construction sector is burdened with high prevalence of work-related diseases and health-issues. To determine the number and age of construction workers in Croatia with temporary or permanent work limitation status, as well as to identify the most common health causes of such work limitation. A retrospective cross-sectional study was performed using the data from 2534 construction workers, aged between 18 and 65 years, who underwent standardized routine occupational health examinations between 2011 and 2015. Thorough medical history and medical record reviews, blood and urine analyses, vision parameters and hearing range evaluation, as well as mental health assessment were conducted on every study participant. A total of 210 construction workers (8.29%) received occupational/work limitation status (either temporary or permanent). Four main categories of work limitation were high blood pressure, disorders of the liver and digestive system, hearing loss and amblyopia, comprising 61.69% of all diagnoses. A total of 37.62% of workers with work limitation status had two or more different diagnoses (i.e. co-morbid conditions). Those with work limitation (either temporary or long-term) were significantly older than those fit enough to work (p-value <0.00001). This type of organized screening represents a significant preventative effort in the construction industry, as workers may become more cognizant of the conditions that may affect their work ability.

Pura AppliE 36 (2003) 33], the authors have developed a method based on the local properties of dielectric permittivity tensor and on Mohr's plane graphical construction in order to study the behaviour of locally plane light waves in anisotropic media. In this paper, this alternative methodology is compared with the traditional one, by emphasizing the simplicity of the former when studying ray propagation through uniaxial media (comparison is possible since, in this case, traditional construction becomes also plane). An original and simple graphical method is proposed in order to determine the direction of propagation given by the wave vector from the knowledge of the extraordinary ray direction (given by Poynting vector). Some properties of light rays in these media not described in the literature are obtained. Finally, two applications are considered: a description of optical birefringence under normal incidence and the study of negative refraction in uniaxial media.

Rates of occupational injury among immigrant workers are widely believed to be underestimated. The goal of this study was to enhance understanding of the burden of occupational injury and the work organization factors underlying injury among immigrant Latino residential construction workers. Prospective data were obtained from a community-based sample of Latino residential construction workers (N = 107) over a 3-month period. Twenty-eight participants were injured, resulting in an injury incidence rate of 55.0/100 FTE (95% CI = 41.4-71.6) during the 3-month observation period. The injury rate involving days away from work during the observation period was 3.9/100 FTE (CI = 0.2-7.2). Injuries were elevated among roofers relative to framers and general construction workers. Roofers had elevated exposure to a variety of deleterious work organization factors. Although imprecise given the small sample, our results suggest a threefold to fourfold underestimate of the injury burden to immigrant Latino construction workers. Work organization may contribute to elevated rates of non-fatal occupational injury, particularly among roofers. Copyright © 2012 Wiley Periodicals, Inc.

Objective To develop a fatigue assessment scale and test its reliability and validity for commercial construction workers. Methods Using a two-phased approach, we first identified items for the development of a Fatigue Assessment Scale for Construction Workers (FASCW) through review of existing scales in the scientific literature, key informant interviews (n=11) and focus groups (3 groups with 6 workers each) with construction workers. The second phase included assessment for the reliability, validity and sensitivity of the new scale using a repeated-measures study design with a convenience sample of construction workers (n=144). Results Phase one resulted in a 16-item preliminary scale that after factor analysis yielded a final 10-item scale with two sub-scales (“Lethargy” and “Bodily Ailment”).. During phase two, the FASCW and its subscales demonstrated satisfactory internal consistency (alpha coefficients were FASCW (0.91), Lethargy (0.86) and Bodily Ailment (0.84)) and acceptable test-retest reliability (Pearson Correlations Coefficients: 0.59–0.68; Intraclass Correlation Coefficients: 0.74–0.80). Correlation analysis substantiated concurrent and convergent validity. A discriminant analysis demonstrated that the FASCW differentiated between groups with arthritis status and different work hours. Conclusions The 10-item FASCW with good reliability and validity is an effective tool for assessing the severity of fatigue among construction workers. PMID:25603944

Work-related mental ill-health appears to be increasing. Population-based data on incidence are scarce but in the United Kingdom occupational physicians and psychiatrists report these conditions to voluntary surveillance schemes. To estimate the incidence of work-related stress and mental illness reported 1996-2001 by occupational physicians and 1999-2001 by psychiatrists. Estimated annual average incidence rates were calculated by sex, occupation and industry against appropriate populations at risk. An in-house coding scheme was used to classify and analyse data on precipitating events. An estimated annual average of 3,624 new cases were reported by psychiatrists, and 2,718 by occupational physicians; the rates were higher for men in reports based on the former and for women on the latter. Most diagnoses were of anxiety/depression or work-related stress, with post-traumatic stress accounting for approximately 10% of cases reported by psychiatrists. High rates of ill-health were seen among professional and associated workers and in those in personal and protective services. Factors (such as work overload) intrinsic to the job and issues with interpersonal relations were the most common causes overall. The steep increase in new cases of work-related mental ill-health reported by occupational physicians since 1996 may reflect a greater willingness by workers to seek help but may also signify an increasing dissonance between workers' expectations and the work environment. Greater expertise is needed to improve the workplace by adjustment of job demands, improvement of working relations, increasing workers' capacities and management of organizational change.

Workers represent half the world's population and are major contributors to economic and social development. Tobacco consumption in construction site workers has been considered a big challenge. (1) To assess the prevalence of nicotine dependence among tobacco users. (2) To study the correlates of nicotine dependence among the construction site workers. A cross sectional study was conducted using a predesigned and pretested structured proforma. The study was conducted among all construction site workers aged 18yrs and above in campus of Hamdard Institute of Medical Sciences and Research and associated HAH centenary hospital, New Delhi. Karl Fagerstrom Nicotine Dependence Questionnaire was used to assess dependence on nicotine. The mean age of construction site workers was 32.04±11.6 years. Among the workers, majority (91%) were tobacco user. Among the users, 60% found it difficult to refrain from smoking/chewing in places where use of tobacco is not allowed (e.g. hospitals, government offices, cinemas, Libraries etc). 55% of the users smoked or chewed tobacco during the first hours after waking than during the rest of the day. On multivariate analysis, the factors which were found to be significantly associated with nicotine dependence were lower income group (OR 2.57, CI:1.66-3.99), smokeless tobacco use (OR 2.36, CI:1.30-4.27) and lower education (OR = 2.86 (95% CI 1.97-4.16) for illiterate). The prevalence of tobacco use (91%) among construction workers is very high compared to that in the general population. Recognition of construction sites as work places and proper implementation of law is needed.

Under the support of GIS technology and the TM images of Xixi National Wetland Park, this paper studied the past ten years' landscape pattern change and its driving forces of Xixi Wetland. The results showed that the landscape diversity index increased from 1.7854 in 1993 to 1.8438 in 2001 and 2.2096 in 2003, and the landscape fragmentation index increased from 0.0036 in 1993 to 0.0042 in 2001, and 0.0047 in 2003, suggesting that the landscape fragmentation was increased with time. Human activity was the main driving force, while the exploitation of real estate was the main internal factor of the landscape pattern change of Xixi wetland. In addition, social and economic development level had a strong effect on the overall diversity of the landscape.

Early marine growth of pink salmon in Prince William Sound and the coastal gulf of Alaska during years of low and high survival

Although early marine growth has repeatedly been correlated with overall survival in Pacific salmon Oncorhynchus spp., we currently lack a mechanistic understanding of smolt-to-adult survival. Smolt-to-adult survival of pink salmon O. gorbuscha returning to Prince William Sound was lower than average for juveniles that entered marine waters in 2001 and 2003 (3% in both years), and high for those that entered the ocean in 2002 (9%) and 2004 (8%). We used circulus patterns from scales to determine how the early marine growth of juvenile pink salmon differed (1) seasonally during May-October, the period hypothesized to be critical for survival; (2) between years of low and high survival; and (3) between hatchery and wild fish. Juvenile pink salmon exhibited larger average size, migrated onto the continental shelf and out of the sampling area more quickly, and survived better during 2002 and 2004 than during 2001 and 2003. Pink salmon were consistently larger throughout the summer and early fall during 2002 and 2004 than during 2001 and 2003, indicating that larger, faster-growing juveniles experienced higher survival. Wild juvenile pink salmon were larger than hatchery fish during low-survival years, but no difference was observed during high-survival years. Differences in size among years were determined by some combination of growing conditions and early mortality, the strength of which could vary significantly among years. ??

The European Directive 96/29/EURATOM and its transposition into national legislation demands the application of radiation protection measures if the presence of radon and radon decay products leads to significant increase in exposures of workers. Irish legislation further demands that laboratories carrying out radon measurements operate a high level quality assurance programme. As a result of a reconnaissance survey regular measurements of show cave guides have been made in order to assess exposure to radon in such workplaces and to ascertain that the limits set for radon are not exceeded. In 2000, an action level of 400 Bqm-3, was established. Doses in the range 0.3-12.0 mSv have been estimated for workers for the period 2001-2006.

Although lung cancer risks can vary by race/ethnicity and by construction occupation, these risks have not been examined extensively. This study analyzed 110,937 lung cancer cases identified from the California Cancer Registry between 1988 and 2007. Mean age at diagnosis, proportion diagnosed at an advanced stage, and proportion with 3-year survival were calculated for lung cancer cases employed in the construction industry. Case-control methodology was also used to assess the risk of lung cancer. Morbidity odds ratios (MORs) were estimated by conditional logistic regression. Construction workers were found to have a significantly elevated risk for all lung cancer combined (MOR = 1.57) and for each lung cancer histologic subtype examined. All construction occupations, except managers/engineers and supervisors, had a significantly elevated risk for all lung cancer combined. Roofers and welders had the highest risks for total lung cancer and for each of the histologic subtypes. Construction workers in each of the four race/ethnicity groups also had significantly increased lung cancer risks. Compared to non-construction workers, construction workers were diagnosed at an earlier age, at a more advanced stage, and had significantly lower 3-year survival, though differences were modest. These findings justify additional reductions in carcinogenic exposures in construction, and increased support for smoking cessation programs at construction sites.

Approximately 20 million nonsmoking workers are employed in workplaces without restrictions on smoking and are potentially exposed to secondhand smoke--a Class A carcinogen. These workers are largely in the service industry, in southern and western states and in non-urban areas. The Occupational Safety and Health Administration's (OSHA's) 1994 proposal for smoke-free workplaces (withdrawn in 2001) was attacked by many interest groups that may no longer oppose this protection. Federal regulation for smoke-free workplaces is needed for workers, who are not protected by state and local smoke-free laws. This policy could save thousands of lives each year, and prevent significant illness. Twenty-one states have "state plans" that would allow more protective laws. Of the 29 states under OSHA, 11 have comprehensive smoke-free statutes. Changes in the policy environment and in institutions such as unions, restaurant associations, and the tobacco industry since 2001 may improve the prospects for federal action and reduce disparities that currently characterize exposure to secondhand smoke.

2017-01-01

Collaborative efforts between the National Institute for Occupational Safety and Health (NIOSH) and the American Society of Safety Engineers (ASSE) led to a report focusing on overlapping occupational vulnerabilities, specifically small construction businesses employing young, non-native workers. Following the report, an online survey was conducted by ASSE with construction business representatives focusing on training experiences of non-native workers. Results were grouped by business size (50 or fewer employees or more than 50 employees). Smaller businesses were less likely to employ a supervisor who speaks the same language as immigrant workers (p < .001). Non-native workers in small businesses received fewer hours of both initial safety training (p = .005) and monthly ongoing safety training (p = .042). Immigrant workers in smaller businesses were less likely to receive every type of safety training identified in the survey (including pre-work safety orientation [p < .001], job-specific training [p < .001], OSHA 10-hour training [p = .001], and federal/state required training [p < .001]). The results highlight some of the challenges a vulnerable worker population faces in a small business, and can be used to better focus intervention efforts. Among businesses represented in this sample, there are deflcits in the amount, frequency, and format of workplace safety and health training provided to non-native workers in smaller construction businesses compared to those in larger businesses. The types of training conducted for non-native workers in small business were less likely to take into account the language and literacy issues faced by these workers. The findings suggest the need for a targeted approach in providing occupational safety and health training to non-native workers employed by smaller construction businesses. PMID:29375194

The construction industry has been identified as one of the most hazardous industries. The risk of constructionrelated workers is far greater than that in a manufacturing based industry. However, some steps can be taken to reduce worker risk through effective injury prevention strategies. In this article, k-means clustering methodology is employed in specifying the factors related to different worker types and in identifying the patterns of industrial occupational accidents. Accident reports during the period 1998 to 2008 are extracted from case reports of the Northern Region Inspection Office of the Council of Labor Affairs of Taiwan. The results show that the cluster analysis can indicate some patterns of occupational injuries in the construction industry. Inspection plans should be proposed according to the type of construction-related workers. The findings provide a direction for more effective inspection strategies and injury prevention programs.

Construction is a major source of employment in many countries. In construction, workers perform a great diversity of activities, each one with a specific associated risk. The aim of this paper is to identify workers who are at risk of accidents with severe consequences and classify these workers to determine appropriate control measures. We defined 48 groups of workers and used the Bayesian theorem to estimate posterior probabilities about the severity of accidents at the level of individuals in construction sector. First, the posterior probabilities of injuries based on four variables were provided. Then the probabilities of injury for 48 groups of workers were determined. With regard to marginal frequency of injury, slight injury (0.856), fatal injury (0.086) and severe injury (0.058) had the highest probability of occurrence. It was observed that workers with <1 year's work experience (0.168) had the highest probability of injury occurrence. The first group of workers, who were extensively exposed to risk of severe and fatal accidents, involved workers ≥ 50 years old, married, with 1-5 years' work experience, who had no past accident experience. The findings provide a direction for more effective safety strategies and occupational accident prevention and emergency programmes.

Musculoskeletal injuries in construction: a review of the literature.

PubMed

Schneider, S P

2001-11-01

The first step in addressing any problem is recognition of the problem and a measure of its size and scope. There have been few reviews to date of the evidence of a musculoskeletal disorders problem in construction, particularly in the United States. Construction contractors in the United States have questioned the existence of a musculoskeletal disorders problem in construction, so a review of the evidence is warranted. The types of evidence reviewed include: 1) historical evidence, 2) injury data, 3) workers' compensation data, 4) medical exam data, 5) survey data, and 6) exposure data. Injury data generally represent injuries that the employers have identified as work-related and recorded or reported. Workers' compensation data are from cases that have been filed by workers for compensation and quite often represent only "closed" cases where compensation has been awarded. Medical exam data are from physical examinations of workers. Symptom survey data are the most inclusive and show the number of workers who self-report musculoskeletal problems. Exposure data include measurements made of exposure to musculoskeletal risk factors. The existing data show construction workers to be at significant risk of musculoskeletal injury, specifically related to the work they do. Their risk of musculoskeletal injury is much higher than that of other workers who have less heavy work, about 50 percent higher than all other workers. Several trades have been extensively studied, while others have been studied to a lesser extent. While the exact relationship between exposures and injuries is complex and often multifaceted, it would be difficult to deny the existence of the problem and the fact that these injuries are, to a great extent, related to the work that construction workers perform.

Studies have found that young workers are at risk for injuries. The risk for accidents is high within construction, indicating that young workers may be especially vulnerable in this industry. In Norway, it is possible to enter the construction industry as a full time worker at the age of 18. The aim of this paper was to explore how young construction workers are received at their workplace with regards to OHS-training. The study was designed as a qualitative case study. Each case consisted of a young worker or apprentice (< 25 years), a colleague, the immediate superior, the OHS manager, and a safety representative in the company. The interviews were recorded and analyzed through content analysis. The results showed that there were differences between large and small companies, where large companies had more formalized routines and systems for receiving and training young workers. These routines were however more dependent on requirements set by legislators and contractors more than by company size, since the legislation has different requirements with impact on OHS.

Employee’s occupational stress and safety performance are highly related, which has been generally recognized by the researchers. We did this research to understand the status of the stress for construction workers, and explore the influence factors of pressure source with characteristics of construction industry. Based on the results of previous studies, we designed questionnaire to collect the influence factors on occupational stressors. The study selected workers from certain construction units at the grass-roots level as sample source. According to the results of the questionnaire, we redesigned the interview outline, and did the semi-structured interviews on workers randomly selected. Finally, we developed a scale which combined the characteristics of construction projects in China. Using SPSS software for factor analysis, reliability analysis, and descriptive statistical analysis, the results show that there are six factors affecting the workers’ occupational stress, including The Work Itself, Family-Work, Career Development, Organization Style, Interpersonal Relationship and Role Management Style. The work itself is the main sources of occupational stress. The results can be used by the construction company to provide guidance for workers to control and manage occupational stress.

Degrees of connectivity: Systems model for upstream risk assessment and mitigation.

There is growing recognition that in order to further improve safety performance, attention needs to be given beyond the immediate working conditions and worker actions. A systems approach to construction safety enables considering: multiple project elements simultaneously; connections between different elements; and all system elements affected by safety risk. This paper describes recent and current research to conceptualize a typical building project in terms of connections between workers, activities, and design elements, and to verify and analyze impacts of the design and worker interactions on worker safety. Prior research provides the basis for a network tying the design elements, construction activities, and work crews on a typical building project together along with the extent of interaction between each of the system elements in terms of safety. In conjunction with this systems approach, the researchers propose a concept for viewing and managing construction safety through four different types of connections, or "degrees of connectivity," between the different workers, activities, and design elements in the system. The degrees of connectivity are defined as: interacting with the design element during its construction (DoC #1); interacting with the design element in its final form to attach another component to it (DoC #2) or by working in the vicinity of it (DoC #3); and indirectly interacting with the design element through another worker (DoC #4). To support and verify the presence of the concept in practice, the researchers conducted a survey of construction personnel. The survey results confirm that the four different degrees of connectivity are present and felt during construction operations, and indicate that attention should be given to all design elements, activities, and workers to which a worker is "connected". According to the survey respondents, DoC's #1 and #2 are recognized as the most widely present on construction sites. Eighty percent of the respondents believe that the design element has a moderate or greater impact on worker safety while it is being constructed. These initial research steps provide the starting point for continuing study that aims to develop and demonstrate the degrees of connectivity concept linking workers and design elements, with the goal of understanding how to design a project and work operations in order to improve safety during construction.

The purpose of this study was to apply the Intervention Mapping approach as a framework in the development of a worksite intervention to improve the work ability of construction workers. Development of an intervention by using the Intervention Mapping approach. Construction worksite. Construction workers aged 45 years and older. According to the principles of Intervention Mapping, evidence from the literature was combined with data collected from stakeholders (e.g., construction workers, managers, providers). The Intervention Mapping approach resulted in an intervention with the following components: (1) two individual visits of a physical therapist to lower the physical workload, (2) a Rest-Break tool to improve the balance between work and recovery, and (3) two empowerment training sessions to increase the range of influence at the worksite. Application of Intervention Mapping in the development of a worksite prevention program was useful in the construction industry to obtain a positive attitude and commitment. Stakeholders could give input regarding the program components as well as provide specific leads for the practical intervention strategy. Moreover, it also gives insight in the current theoretical and empirical knowledge in the field of improving the work ability of older workers in the construction industry.

Millions of U.S. workers are at risk for a work-related motor vehicle crash. Fatality data show that across all industries, motor vehicle crashes are consistently the leading cause of work-related fatalities. Of 43,025 work-related fatalities reported by BLS between 2003 and 2010, 10,202 were the result of single- or multiple-vehicle crashes of workers driving or riding in a vehicle on a public roadway, and 2,707 were pedestrian workers struck by a motor vehicle. During the same period, an additional 2,487 workers died in crashes that occurred off a public roadway or on industrial premises (BLS, 2013). PMID:26251557

This paper aims to describe health insurance coverage among different types of workers in Brazil. Health insurance coverage and labor market insertion are used to define homogeneous groups of workers. The Grade of Membership method is used to build a typology of workers. The database was the Brazilian National Household Survey (PNAD) for 1998 and 2003, including a health survey. Five worker profiles were defined. The key variables were: health insurance coverage, schooling, and work status. The main findings show a positive association between health insurance coverage, income from work, and trade union membership.

To estimate the prevalence and to analyze the factors associated with self-reported hearing handicap by construction workers in the state of Mato Grosso, Brazil. A cross-sectional study was conducted with 866 construction and heavy construction workers. Participants responded to an epidemiological survey subdivided in: identification data, sociodemographic data; lifestyle; work environment characteristics; occupational exposure factors; hearing protection measures; and hearing handicap inventory to quantify the psychosocial consequences of work-related hearing loss. The prevalence of hearing impairment among workers in the construction sector was 14.43% (n = 125). There were 311 emotional and social complaints related to hearing problems. Hearing handicap was associated with: 60 or over age group (PR = 1.94, 95%CI 1.01 - 3.71); alcohol consumption (PR = 1.94, 95%CI 1.38 - 2.73); direct exposure to noise (PR = 1.75; 95%CI 1.03 - 2.97); exposure to dust (PR = 1.59, 95%CI 1.13 - 2.24); non-use of earplugs (PR = 1.39, 95%CI 1.00 - 1.93); and non-use of neck flap cap (PR = 1.52, 95%CI 1.09 - 2.13). We observed a high prevalence of hearing impairment among workers in the construction sector associated with: individuals aged 60 years or older; alcoholism; exposure to noise and dust; non-use of earplugs; and non-use of neck flap cap. Therefore, it is necessary to implement policies aimed at preserving the hearing health of construction and heavy construction workers.

Migration and Health in the Construction Industry: Culturally Centering Voices of Bangladeshi Workers in Singapore

Construction workers globally face disproportionate threats to health and wellbeing, constituted by the nature of the work they perform. The workplace fatalities and lost-time injuries experienced by construction workers are significantly greater than in other forms of work. This paper draws on the culture-centered approach (CCA) to dialogically articulate meanings of workplace risks and injuries, voiced by Bangladeshi migrant construction workers in Singapore. The narratives voiced by the participants suggest an ecological approach to workplace injuries in the construction industries, attending to food insecurity, lack of sleep, transportation, etc. as contextual features of work that shape the risks experienced at work. Moreover, participant voices point to the barriers in communication, lack of understanding, and experiences of incivility as features of work that constitute the ways in which they experience injury risks. The overarching discourses of productivity and efficiency constitute a broader climate of threats to worker safety and health. PMID:28146056

Objective This study explored the risk of respiratory cancer and non-malignant respiratory disease (NMRD)-related mortality among older construction workers. Methods Analyzed data from the 1992–2010 RAND Health and Retirement Study (HRS) and the HRS National Death Index – Cause of Death file. About 25,183 workers aged 50 years and older were examined, including 5,447 decedents and 19,736 survivors, of which 1,460 reported their longest job was in construction. Multinomial logistic regression assessed the differences in mortality between workers’ longest occupations, controlling for confounders. Results After adjusting for smoking and demographics, construction workers were almost twice as likely to die from respiratory cancer (OR = 1.65; CI: 1.10–2.47) or NMRD (OR = 1.73; CI: 1.16–2.58) compared to white-collar workers. Conclusions This study adds to the growing evidence that respiratory cancer and NMRD are frequently associated with construction exposure. PMID:27500180

Allergy was found in 25.5% of the construction industry workers, in this 7.7% were those with eczema and dermatitis, 17.8%--those with latent allergy (in 12.2% allergy was accompanied by dermatoses of non-allergic etiology, 5.6% construction workers no skin changes). The highest number of skin positive tests was that with chromium (22.4% of affected workers) and cobalt (12.4%). Most susceptible to allergy were: painters, bricklayers, carpenters, joiners, reinforcing concretors, terrazers, concretors, electricians, smiths and reinforcers. In addition, allergy was found to be dependent on age and length of employment.

While smoking is the major cause of chronic obstructive pulmonary disease (COPD), occupational exposures to vapors, gases, dusts, and fumes (VGDF) increase COPD risk. This case-control study estimated the risk of COPD attributable to occupational exposures among construction workers. The study population included 834 cases and 1243 controls participating in a national medical screening program for older construction workers between 1997 and 2013. Qualitative exposure indices were developed based on lifetime work and exposure histories. Approximately 18% (95% CI = 2-24%) of COPD risk can be attributed to construction-related exposures, which are additive to the risk contributed by smoking. A measure of all VGDF exposures combined was a strong predictor of COPD risk. Construction workers are at increased risk of COPD as a result of broad and complex effects of many exposures acting independently or interactively. Control methods should be implemented to prevent worker exposures, and smoking cessation should be promoted. © 2015 The Authors.

Construction workers accident is the highest number compared with other industries and falls are the main cause of fatal and serious injuries in high rise projects. Generally, construction workers accidents are caused by unsafe act and unsafe condition that can occur separately or together, thus a safety monitoring system based on influencing factors is needed to achieve zero accident in construction industry. The dynamic characteristic in construction causes high mobility for workers while doing the task, so it requires a continuously monitoring system to detect unsafe condition and to protect workers from potential hazards. In accordance with the unique nature of project, fuzzy logic approach is one of the appropriate methods for workers safety monitoring on site. In this study, the focus of discussion is based on the characteristic of construction projects in analyzing "potential hazard" and the "protection planning" to be used in accident prevention. The data have been collected from literature review, expert opinion and institution of safety and health. This data used to determine hazard identification. Then, an application model is created using Delphi programming. The process in fuzzy is divided into fuzzification, inference and defuzzification, according to the data collection. Then, the input and final output data are given back to the expert for assessment as a validation of application model. The result of the study showed that the potential hazard of construction workers accident could be analysed based on characteristic of project and protection system on site and fuzzy logic approach can be used for construction workers accident analysis. Based on case study and the feedback assessment from expert, it showed that the application model can be used as one of the safety monitoring tools.

Purpose To determine whether the 2003 Accreditation Council for Graduate Medical Education (ACGME) duty hours reform affected medical knowledge as reflected by written board scores for internal medicine (IM) residents. Method The authors conducted a retrospective cohort analysis of postgraduate year 1 (PGY-1) Internal Medicine residents who started training before and after the 2003 duty hour reform using a merged data set of American Board of Internal Medicine (ABIM) Board examination and the National Board of Medical Examiners (NMBE) United States Medical Licensing Examination (USMLE) Step 2 Clinical Knowledge test scores. Specifically, using four regression models, the authors compared IM residents beginning PGY-1 training in 2000 and completing training unexposed to the 2003 duty hours reform (PGY-1 2000 cohort, n = 5,475) to PGY-1 cohorts starting in 2001 through 2005 (n = 28,008), all with some exposure to the reform. Results The mean ABIM board score for the unexposed PGY-1 2000 cohort (n = 5,475) was 491, SD = 85. Adjusting for demographics, program, and USMLE Step 2 exam score, the mean differences (95% CI) in ABIM board scores between the PGY-1 2001, 2002, 2003, 2004 and 2005 cohorts minus the PGY-1 2000 cohort were −5.43 (−7.63, −3.23), −3.44 (−5.65, −1.24), 2.58 (0.36, 4.79), 11.10 (8.88, 13.33) and 11.28 (8.98, 13.58) points respectively. None of these differences exceeded one-fifth of an SD in ABIM board scores. Conclusions The duty hours reforms of 2003 did not meaningfully affect medical knowledge as measured by scores on the ABIM board examinations. PMID:24556772

A large-scale workplace-based suicide prevention and early intervention program was delivered to over 9,000 construction workers on building sites across Queensland. Intervention components included universal General Awareness Training (GAT; general mental health with a focus on suicide prevention); gatekeeper training provided to construction worker volunteer ‘Connectors’; Suicide First Aid (ASIST) training offered to key workers; outreach support provided by trained and supervised MIC staff; state-wide suicide prevention hotline; case management service; and postvention support provided in the event of a suicide. Findings from over 7,000 workers (April 2008 to November 2010) are reported, indicating strong construction industry support, with 67% building sites and employers approached agreeing to participate in MIC. GAT participants demonstrated significantly increased suicide prevention awareness compared with a comparison group. Connector training participants rated MIC as helpful and effective, felt prepared to intervene with a suicidal person, and knew where to seek help for a suicidal individual following the training. Workers engaged positively with the after-hours crisis support phone line and case management. MIC provided postvention support to 10 non-MIC sites and sites engaged with MIC, but not yet MIC-compliant. Current findings support the potential effectiveness and social validity of MIC for preventing suicide in construction workers. PMID:22163201

Prevalence ratios (PRs) and 95% confidence intervals (CIs) were obtained from fitted logistic regression models. Overall weighted injury prevalence during the previous three months was 77 per 10,000 workers. Age-adjusted injury prevalence was greatest for Construction and Extraction workers (169.7/10,000) followed by Production (160.6) among occupations, while workers in the Construction industry sector (147.9) had the highest injury prevalence followed by the Agriculture/Forestry/Fishing/Mining/Utilities sector (122.1). Overweight and obese workers were 26% to 45% more likely to experience injuries than normal-weight workers. The prevalence of injury, highest for Construction workers, gradually increased as body mass index levels increased in most occupational and industry groups.

The overall goal of this research project was to assess ethnic disparities in monetary compensation among construction workers injured on the job through the linkage of medical records and workers' compensation data. Probabilistic linkage of medical records with workers' compensation claim data. In the final multivariable robust regression model, compensation was $5824 higher (P = 0.030; 95% confidence interval: 551 to 11,097) for white non-Hispanic workers than for other ethnic groups when controlling for injury severity, affected body region, type of injury, average weekly wage, weeks of temporary total disability, percent permanent partial disability, death, or attorney use. The analysis indicates that white non-Hispanic construction workers are awarded higher monetary settlements despite the observation that for specific injuries the mean temporary total disability and permanent partial disability were equivalent to or lower than those in Hispanic and black construction workers.

Health and safety implications of recruitment payments in migrant construction workers.

The Middle East construction sector is heavily reliant on a migrant workforce that predominantly originates from South Asia. It is common practice for migrant construction workers to pay a local labour recruiter the equivalent of one or more years' prospective overseas salary to secure employment, work and travel permits and transportation. The occupational health and safety implications of these financial arrangements remain unexplored. To examine associations between payment to a labour recruiter, perceived general health and worksite accidents among migrant construction workers in the Middle East. A questionnaire was completed by a convenience sample of predominantly Indian migrant construction workers drawn from a large construction project. The relationship between payment and risk of poor health and workplace accidents was assessed using multivariate logistic regression models (crude and adjusted for socio-demographic and occupational factors). There were 651 participants. The majority (58%) of migrant construction workers had paid a labour recruiter and ~40% had experienced a worksite accident. Between 3% (labourers) and 9% (foremen) perceived their health to be poor. Labourers and skilled workers who had paid a labour recruiter were significantly more likely to have experienced a worksite accident in the previous 12 months. Skilled workers, but not labourers and foremen, who had paid a labour recruiter were at increased risk of poor health. The mechanisms linking labour recruiter payments to adverse safety and health outcomes warrant investigation with a view to developing interventions to erode these links. © The Author 2014.

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

Scintillation Detector for the Measurement of Ultra-Heavy Cosmic Rays on the Super-TIGER Experiment

We discuss the design and construction of the scintillation detectors for the Super-TIGER experiment. Super-TIGER is a large-area (5.4sq m) balloon-borne experiment designed to measure the abundances of cosmic-ray nuclei between Z= 10 and Z=56. It is based on the successful TIGER experiment that flew in Antarctica in 2001 and 2003. Super-TIGER has three layers of scintillation detectors, two Cherenkov detectors and a scintillating fiber hodoscope. The scintillation detector employs four wavelength shifter bars surrounding the edges of the scintillator to collect the light from particles traversing the detector. PMTs are optically coupled at both ends of the bars for light collection. We report on laboratory performance of the scintillation counters using muons. In addition we discuss the design challenges and detector response over this broad charge range including the effect of scintilator saturation.

The transient nature of construction work makes it difficult to conduct longitudinal worksite-based health promotion activities. As part of a workplace health assessment pilot study, we worked with a commercial lunch truck company to disseminate four types of health education materials including cancer screening, workplace injury prevention, fruit and vegetable consumption, and smoking cessation to construction workers purchasing food items from the truck during their job breaks. Two weeks following the worksite assessment, we followed up with these workers to ascertain their use of the health promotion materials. Of the 54 workers surveyed, 83% reported reviewing and sharing the cancer screening materials with their families, whereas 44% discussed the cancer screening materials with coworkers. Similar proportions of workers reviewed, shared, and discussed the other health promotion materials with their family. Lunch trucks may be an effective strategy and delivery method for educating construction workers on healthy behaviors and injury prevention practices.

Much literature documents elevated psychiatric symptoms among adults after the terrorist attacks of September 11, 2001 (9/11). We, however, know of no research in children that examines emergency mental health services following 9/11. We test whether children's emergency services for crisis mental health care rose above expected values in September 2001. We applied time-series methods to California Medicaid claims (1999-2003; N = 127,200 visits). Findings in California indicate an 8.7% increase of children's emergency mental health visits statistically attributable to 9/11. Non-Hispanic white more than African American children account for this acute rise in emergency services.

National estimates of occupational asthma (OA) in the United States are sparse. Using data from the Third National Health and Nutrition Examination Survey (NHANES III) 1988-1994, we analyzed associations between occupation and work-related asthma and work-related wheezing among U.S. workers. This study identified several occupations that were at risk of developing work-related asthma and/or wheezing, with cleaners and equipment cleaners showing the highest risks. Other major occupations identified were farm and agriculture; entertainment; protective services; construction; mechanics and repairers; textile; fabricators and assemblers; other transportation and material moving occupations; freight, stock, and material movers; and motor vehicle operators. The population attributable risks for work-related asthma and work-related wheezing were 26% and 27%, respectively. This study adds evidence to the literature that identifies work-related asthma as an important public health problem. Several occupations are targeted for additional evaluation and study. Of particular interest are cleaners, which are being increasingly reported as a risk group for asthma. Future intervention strategies need to be developed for effective control and prevention of asthma in the workplace. Copyright 2003 Wiley-Liss, Inc.

Workers' medication as occupational risk at construction site with formworks.

2017-01-01

Accidents in the construction sector are a cause for concern. The influence of many different factors in construction accidents have been studied (age, company size, length of service, deviation, drugs or alcohol consumption, etc.) but the influence of medicinal substances in specific construction activities has not been evaluated until now. The aim of the research presented here is to identify the effect of different medicinal substances on the occupational risk levels of construction activities with formworks. An expert panel was selected in order to quantify the individual risk of each medication for each individual construction activity. Results showed that narcotics, antipsychotics, and hypnotics had the highest risk values, and the use of cranes and cutting materials were considered the most dangerous activities for a medicated worker. Data obtained in this research can help reduce the negative effects of the substances studied on the occupational safety of construction workers. A better knowledge of the risk levels according to the current capabilities of workers under the effects of medication is a powerful tool in planning safer construction activities.

Kidney disease is emerging as an arsenic (As)-linked disease outcome, however further evidence of this association is warranted. Our first objective for this paper was to examine the potential renal toxicity of As exposure in Bangladesh. Our second objective relates to examining whether the previously reported positive association between urinary creatinine (uCrn) and As methylation may be explained by renal function. We had hypothesized that these associations relate to supply and demand for s-adenosylmethionine, the methyl donor for both creatine synthesis and As methylation. Alternatively, renal function could influence both As and creatinine excretion, or the As metabolites may influence renal function, which in turn influences uCrn. We conducted a cross-sectional study (N = 478) of adults, composed of a sample recruited in 2001 and a sample recruited in 2003. We assessed renal function using plasma cystatin C, and calculated the estimated glomerular filtration rate (eGFR). Consistent with renal toxicity of As, log-uAs had a marginal inverse association with eGFR in the 2003 sample (b = −5.6, p = 0.07), however this association was not significant in the 2001 sample (b = −1.9, p = 0.24). Adjustment for eGFR did not alter the associations between uCrn and the %uAs metabolites, indicating that GFR does not explain these associations. Increased eGFR was associated with increased odds of having %uInAs >12.2% (2001: OR = 1.01, 95%CI (1.00,1.03); 2003: OR = 1.04, 95%CI (1.01,1.07)). In the 2003 sample only, there was a negative association between eGFR and %uDMA (b = −0.08, p = 0.02). These results may indicate differential effects of renal function on excretion of InAs and DMA. Alternatively, a certain methylation pattern, involving decreased %InAs and increased %DMA, may reduce renal function. Given that these studies were cross-sectional, we cannot distinguish between these two possibilities. Discrepancies between the samples may be due to the higher As exposure, poorer nutrition, and lower As methylation capacity in the 2003 sample. PMID:25438247

To examine the construct validity of the Individual Work Performance Questionnaire (IWPQ). A total of 1424 Dutch workers from three occupational sectors (blue, pink, and white collar) participated in the study. First, IWPQ scores were correlated with related constructs (convergent validity). Second, differences between known groups were tested (discriminative validity). First, IWPQ scores correlated weakly to moderately with absolute and relative presenteeism, and work engagement. Second, significant differences in IWPQ scores were observed for workers differing in job satisfaction, and workers differing in health. Overall, the results indicate acceptable construct validity of the IWPQ. Researchers are provided with a reliable and valid instrument to measure individual work performance comprehensively and generically, among workers from different occupational sectors, with and without health problems.

Tetanus is a serious vaccine-preventable disease that remains a significant health risk in certain occupations. Since 2006, Italy has reported the highest number of cases in Europe. Some professions, such as construction workers, are more exposed to tetanus. To evaluate tetanus immunity status and associated factors in construction workers in Italy. A cross-sectional study of construction workers attending for periodic occupational health surveillance at one site in Italy between September 2011 and January 2013. Serum tetanus antitoxin levels were measured and analysed according to demographic and clinical variables. All 5275 workers attending for health surveillance between September 2011 and January 2013 agreed to participate. Protective tetanus antitoxin levels (>0.1 IU/ml) were found in 4116 workers (78%). Multivariate logistic regression analysis suggested that the following risk factors were significantly associated with inadequate immunization status: older age (age >58 years, odds ratio [OR] 1.78, 95% confidence intervals [CIs] 1.76-1.84), poor education (no formal education: OR 3.74, 95% CI: 3.69-3.78), unskilled work tasks (OR 2.71, 95% CI: 2.67-2.77) and country of origin (Egypt: OR 1.72, 95% CI: 1.67-1.77; Morocco: OR 1.69, 95% CI: 1.62-1.76). In this study, a significant proportion of construction workers in Italy were not adequately immunized against tetanus, as required by Italian law. Occupational health professionals should promote and implement vaccination campaigns, especially among migrant workers, for public health and legal reasons.

Work in the construction industry is causing the highest number of mesotheliomas among the residents of the Veneto Region (north-east Italy, 4,5 million inhabitants). To sum up the results on occurrence, asbestos exposure, lung fibre content analyses, and compensation for occupational disease. Case identification and asbestos exposure classification: active search of mesotheliomas that were diagnosed via histological or cytological examinations occurring between 1987 and 2006; a probability of asbestos exposure was attributed to each case, following interviews with the subjects or their relatives and collection of data on the jobs held over their lifetime. Risk estimate among construction workers: the ratio between cases and person-years, the latter derived from the number of construction workers reported by censuses. Lung content of asbestos fibres: examination of lung specimens by Scanning Electron Microscope to determine number and type of fibres. Claims for compensation and compensation awarded: data obtained from the National Institute for Insurance against Occupational Diseases available for the period 1999-2006. of 952 mesothelioma cases classified as due to asbestos exposure, 251 were assigned to work in the construction industry (21 of which due to domestic of environmental exposures), which gives a rate of 4.1 (95% CI 3.6-4.8) x 10(5) x year among construction workers. The asbestos fibre content detected in the lungs of 11 construction workers showed a mean of 1.7 x 10(6) fibres/g dry tissue (range 350,000-3 million) for fibres > 1 micro, almost exclusively due to amphibole fibres. 62% of the claims for compensation were granted but the percentage fell to less than 40% when claims were submitted by a relative, after the death of the subject. The prevalence of mesothelioma occurring among construction workers is high and is associated with asbestos exposure; the risk is underestimated by the subjects and their relatives. All mesotheliomas occurring among construction workers should be granted compensation for occupational disease.

Occupational Safety and Health and Healthy Housing: A Review of Opportunities and Challenges.

PubMed

Jacobs, David E; Forst, Linda

Occupational safety and health (OSH) risks in construction of healthy housing (HH) have not been examined and collaboration between HH and OSH professionals is inadequate. The World Health Organization is developing international HH guidelines and the International Labour Organization is working to improve OSH in construction globally. We searched for exemplary reports (including gray literature) on construction hazards; preventive measures for occupants and workers; OSH frameworks, laws, and regulations; definitions; and HH. Healthy housing construction typically improves ventilation, moisture and mold, pest control, injury hazards, cleanability, maintenance, accessibility, thermal conditioning, and avoidance of toxic building materials. To date, this work is done without explicit requirements for worker health. Construction is among the most hazardous sectors around the globe, although protective measures are well known, including engineering and administrative controls and provision of personal protective equipment. Residential construction, renovation, repair, and maintenance are fragmented, consisting mostly of small companies without proper OSH training, equipment, and knowledge of HH principles. Residential construction is often undertaken by informal or unauthorized workers, putting them at high risk. Reduced exposure to toxic building materials is an example of a benefit for both workers and occupants if OSH and HH collaboration can be improved. By recognizing that homes under new construction or renovation are both a workplace and a residence, HH and OSH initiatives can apply public health principles to occupants and workers simultaneously. This article publishes key definitions, hazards and interventions common to both fields. A global increase in residential construction and renewed global interest in HH poses both risks and opportunities for primary prevention. Policy and practice interventions can benefit the health of occupants and those who work on their homes. Improvements in legislation, regulation, and international frameworks are needed to maximize OSH and HH collaboration and realize significant cobenefits. Occupational safety and health and HH standards should include requirements to protect both workers and occupants. Because homes can also be workplaces, both workers and housing occupants will receive important cobenefits when OSH and HH standards use proven interventions to protect workers and occupants.

2000-04-01

To lay groundwork for identifying patterns of injury etiology, we sought to describe injury experience associated with types of work performed at construction sites by examining workers' compensation (WC) claims for the 32,081 construction workers who built Denver International Airport (DIA). Injury rates and WC payment rates were calculated for 25 types of work based on claims and payroll data reported to DIA's owner-controlled insurance program according to National Council on Compensation Insurance job classifications. By linking DIA claims with corresponding lost-work-time (LWT) claims filed with Colorado's Workers' Compensation Division, we were also able to obtain and examine both total and median lost days for each type of work. Injury experience varied widely among the types of construction work. Workers building elevators and conduits and installing glass, metal, or steel were at particularly high risk of both LWT and non-LWT injury. Median days lost by injured workers was highest (202 days) for driving/trucking. Median days lost for most types of work was much greater than previously reported for construction: 40 days or more for 18 of the 25 types of work analyzed. WC payment rates reflect both number and severity of injuries and were generally not significantly different from expected losses. They were, however, significantly higher than expected for driving/trucking, metal/steel installation, inspection/analysis, and elevator construction. Analysis of injury data by type of work allows targeting of safety resources to high risk construction work and would be useful in prospective surveillance at large construction sites with centrally administered workers' compensation plans.

To get scientific basis for further health education through the research of the road construction workers' KBP before and after the interventions of highway AIDS prevention project. Multi-stage random sampling method was employeed to select workers of 8 sites from 14 sites along highway to investigate their AIDS knowledge, belief and performance (KBP) before and after highway AIDS prevention project. Over 90% of the investigated workers had ever heard about AIDS, and the non-skilled workers of lower educational level improved more after intervention. The correct answer rate of the three transmitting ways of AIDS of drivers which is the focused group of highway before and after intervention had the obvious statistical significance (P<0.05), and the other group's correct answer rates also had improved after intervention. Most people's understanding of preventing AIDS through correct use of condoms when having sex had a statistically significant difference(P<0.05) after prevention. The rates of using condoms of foremen and skilled workers when having sex with commercial sex worker/casual partner increased after intervention. The health education of HIV among the road construction workers is effective and further health education of HIV prevention should be carried out among the road construction workers to improve their knowledge and awareness of avoiding the high-risk behaviors.

To determine the prevalence of inapparent infection with severe acute respiratory syndrome (SARS) among healthcare workers, we performed a serosurvey to test for immunoglobulin (Ig) G antibodies to the SARS coronavirus (SARS-CoV) among 1,147 healthcare workers in 3 hospitals that admitted SARS patients in mid-May 2003. Among them were 90 healthcare workers with SARS. As a reference group, 709 healthcare workers who worked in 2 hospitals that never admitted any SARS patients were similarly tested. The seroprevalence rate was 88.9% (80/90) for healthcare workers with SARS and 1.4% (15/1,057) for healthcare workers who were apparently healthy. The seroprevalence in the reference group was 0.4% (3/709). These findings suggest that inapparent infection is uncommon. Low level of immunity among unaffected healthcare workers reinforces the need for adequate personal protection and other infection control measures in hospitals to prevent future epidemics.

'Newborn skin is thinner, more permeable and less able to withstand the sensitising effects of modern detergents. It is also important to remember that anything placed on, in or around a baby has the capacity to harm' (Trotter, 2004a). The anatomical and functional differences of neonatal skin have been thoroughly reported over the years and there is now a body of evidence to support the above statement (Fatter, 1997; Gelmetti, 2001; Lund, 2001a, 2001b; Medves, 2001; Ertel, 2003; Trotter, 2002, 2004a). The aim of this article is to inform midwives about the potential dangers of chemical ingredients used in personal care products and to suggest simpler skincare regimes. It is anticipated that doing so will reduce the risks of conditions like eczema, asthma and related allergies.

Technology evaluation: adalimumab, Abbott laboratories.

Adalimumab (D2E7), a human monoclonal antibody that binds to and neutralizes TNFa, is being developed by Abbott (formerly Knoll), under license from Cambridge Antibody Technology (CAT), for the potential treatment of inflammatory disorders such as rheumatoid arthritis (RA) and Crohn's disease. It is also being investigated for the potential treatment of coronary heart disease. Phase II studies for Crohn's disease and phase III for RA were ongoing throughout 2001. Limited data are only available for RA. In January 2002, it was reported that phase III trials of adalimumab for RA had been completed, but details have not been published in the primary literature so far. At this time CAT and Abbott expected to file for US approval in the second quarter of 2002 with a launch date anticipated for 2003. Phase III data are expected to be presented at the European League Against Rheumatism meeting in June 2002. In November 2000, Lehman Brothers predicted a US launch in June 2002 with peak US sales of $600 million in 2007 and a launch in non-US markets in 2003 with peak sales in these markets of $300 million in 2008.

A worksite prevention program was developed to promote the work ability of construction workers and thereby prolong a healthy working life. The objective of this paper is to present the design of a randomized controlled trial evaluating the effectiveness of that intervention program compared with usual care for construction workers. The study is designed as a randomized controlled trial with a follow-up of one year. Employees eligible for this study are construction workers performing actual construction work. The worksite intervention will be compared with usual care. This intervention was developed by using the Intervention Mapping approach and consists of the following components: (1) two individual training sessions of a physical therapist to lower the physical workload, (2) a Rest-Break tool to improve the balance between work and recovery, and (3) two empowerment training sessions to increase the influence of the construction workers at the worksite. Outcome measures are assessed at baseline, 3, 6, and 12 months. The primary outcome measures of this study are work ability and health-related quality of life. Secondary outcome measures include need for recovery, musculoskeletal complaints, work engagement and self efficacy. Cost-effectiveness will be evaluated from the company perspective. Moreover, a process evaluation will be conducted. The feasibility of the intervention and the study has been enhanced by creating an intervention program that explicitly appeals to construction workers and will not interfere too much with the ongoing construction. The feasibility and effectiveness of this worksite prevention program will be investigated by means of an effect- and a process evaluation. If proven effective, this worksite prevention program can be implemented on a larger scale within the construction industry. NTR1278.

Construction is a manual, heavy, and complex sector concerning the most fatal accidents and high incidence of occupational illnesses and injuries resulting in days away from work. In Hong Kong, “Pilot Medical Examination Scheme for Construction Workers” was launched in 2014 to detect the health problems of their construction workforce. All registered workers under the Construction Workers Registration Board are eligible to join the scheme. The purpose of this paper is to assess the physical condition, physiological status, and musculoskeletal disorders of 942 construction workers in Hong Kong. This study adopted a two-phase design, which includes a basic medical examination to measure the workers’ physiological parameters, such as blood pressure, resting heart rate, glucose, cholesterol, uric acid, liver function test, and renal function test; as well as a face-to-face interview following the medical examination to collect their demographic information and pain experience. Individual characteristics, including gender, age, obesity, alcohol drinking habit, and sleeping habit influenced the health condition of construction workers. Among the participants, 36.1% and 6.5% of them were overweight and obese, respectively. In addition, 43.0%, 38.4%, 16.2%, and 13.9% of the participants exceeded the thresholds of cholesterol, blood pressure, urea nitrogen, and uric urea, correspondingly. Moreover, 41.0% of the participants suffered musculoskeletal pain, where the most frequent painful parts occur in the lower back, shoulder, knees, leg, and neck. Through these findings, a series of important issues that need to be addressed is pointed out in terms of maintaining the physical well-being and reducing musculoskeletal disorders of construction workers. The finding may have implications for formulating proper intervention strategies for the sustainable development of Hong Kong’s construction industry. PMID:27983612

2004-03-01

We present the time-resolved photometry of V1494 Aql (Nova Aql 1999 No. 2) between 2001 November and 2003 June. The object is confirmed to be an eclipsing nova with a period of 0.1346138(2)d. The eclipses were present in all observed epochs. The orbital light curve shows a rather unusual profile, consisting of a bump-like feature at phase 0.6-0.7 and a dip-like feature at phase 0.2-0.4. These features were probably persistently present in all available observations between 2001 and 2003. A period analysis outside of the eclipses has confirmed that these variations have a period common to the orbital period, and are unlikely to be interpreted as superhumps. We suspect that the structure (probably in the accretion disk) fixed in the binary rotational frame is somehow responsible for this feature.

Keefe, Robert H

2010-05-01

In 2001, the U.S. Department of Health and Human Services published Healthy People 2010, which identified objectives to guide health promotion and to eliminate health disparities. Since 2001, much research has been published documenting racial and ethnic disparities in healthcare. Although progress has been made in eliminating the disparities, ongoing work by public health social workers, researchers, and policy analysts is needed. This paper focuses on racial and ethnic health disparities, why they exist, where they can be found, and some of the key health/medical conditions identified by the U.S. Department of Health and Human Services to receive attention. Finally, there is a discussion of what policy, professional and community education, and research can to do to eliminate racial and ethnic disparities in healthcare.

Is the apparent decrease in injury and illness rates in construction the result of changes in reporting?

PubMed

Welch, Laura S; Dong, Xiuwen; Carre, Francoise; Ringen, Knut

2007-01-01

Injury rates in all industries and in construction in particular have been declining. Inconsistencies in the information suggest some of the apparent decrease may be due to changes in the ways injuries are treated, misclassification of employees, or underreporting. Lost-time injury rates for the largest construction employers declined by as much as 92% between 1988 and 1999. Yet the rate for cases with restricted work activity actually increased from 0.7 to 1.2 per 100 full-time workers between 1990 and 2000, and fatalities among construction workers remain high. In Massachusetts, at least 14% of construction employers misclassified workers as independent contractors, with the effect that injuries to these workers are not recordable. Studies that compare OSHA logs with other data sources find that the OSHA logs do not include a significant proportion of injuries and illnesses identified elsewhere.

A revolution in the building industry over the past decade has spawned a new generation of safer materials and practices, decreasing some health risks for construction workers. Concerned consumers, builders, materials manufacturers, and government regulatory agencies have all contributed to a turn toward "green" building materials and practices, meaning that homeowners and office workers now are better able to live and work in healthier environments, and many construction workers are handling and installing less-toxic materials.

Arrow Lakes Reservoir Fertilization Experiment; Years 4 and 5, Technical Report 2002-2003.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Schindler, E.

This report presents the fourth and fifth year (2002 and 2003, respectively) of a five-year fertilization experiment on the Arrow Lakes Reservoir. The goal of the experiment was to increase kokanee populations impacted from hydroelectric development on the Arrow Lakes Reservoir. The impacts resulted in declining stocks of kokanee, a native land-locked sockeye salmon (Oncorhynchus nerka), a key species of the ecosystem. Arrow Lakes Reservoir, located in southeastern British Columbia, has undergone experimental fertilization since 1999. It is modeled after the successful Kootenay Lake fertilization experiment. The amount of fertilizer added in 2002 and 2003 was similar to the previousmore » three years. Phosphorus loading from fertilizer was 52.8 metric tons and nitrogen loading from fertilizer was 268 metric tons. As in previous years, fertilizer additions occurred between the end of April and the beginning of September. Surface temperatures were generally warmer in 2003 than in 2002 in the Arrow Lakes Reservoir from May to September. Local tributary flows to Arrow Lakes Reservoir in 2002 and 2003 were generally less than average, however not as low as had occurred in 2001. Water chemistry parameters in select rivers and streams were similar to previous years results, except for dissolved inorganic nitrogen (DIN) concentrations which were significantly less in 2001, 2002 and 2003. The reduced snow pack in 2001 and 2003 would explain the lower concentrations of DIN. The natural load of DIN to the Arrow system ranged from 7200 tonnes in 1997 to 4500 tonnes in 2003; these results coincide with the decrease in DIN measurements from water samples taken in the reservoir during this period. Water chemistry parameters in the reservoir were similar to previous years of study except for a few exceptions. Seasonal averages of total phosphorus ranged from 2.11 to 7.42 {micro}g/L from 1997 through 2003 in the entire reservoir which were indicative of oligo-mesotrophic conditions. Dissolved inorganic nitrogen concentrations have decreased in 2002 and 2003 compared to previous years. These results indicate that the surface waters in Arrow Lakes Reservoir were approaching nitrogen limitation. Results from the 2003 discrete profile series indicate nitrate concentrations decreased significantly below 25 {micro}g/L (which is the concentration where nitrate is considered limiting to phytoplankton) between June and July at stations in Upper Arrow and Lower Arrow. Nitrogen to phosphorus ratios (weight:weight) were also low during these months indicating that the surface waters were nitrogen deficient. These results indicated that the nitrogen to phosphorus blends of fertilizer added to the reservoir need to be fine tuned and closely monitored on a weekly basis in future years of nutrient addition. Phytoplankton results shifted during 2002 and 2003 compared to previous years. During 2002, there was a co-dominance of potentially 'inedible' diatoms (Fragilaria spp. and Diatoma) and 'greens' (Ulothrix). Large diatom populations occurred in 2003 and these results indicate it may be necessary to alter the frequency and amounts of weekly loads of nitrogen and phosphorus in future years to prevent the growth of inedible diatoms. Zooplankton density in 2002 and 2003, as in previous years, indicated higher densities in Lower Arrow than in Upper Arrow. Copepods and other Cladocera (mainly tiny specimens such as Bosmina sp.) had distinct peaks, higher than in previous years, while Daphnia was not present in higher numbers particularly in Upper Arrow. This density shift in favor to smaller cladocerans was mirrored in a weak biomass increase. In Upper Arrow, total zooplankton biomass decreased from 1999 to 2002, and in 2003 increased slightly, while in Lower Arrow the biomass decreased from 2000-2002. In Lower Arrow the majority of biomass was comprised of Daphnia throughout the study period except in 2002, while in Upper Arrow the total biomass was comprised of copepods from 2000-2003.« less

Long-term health outcomes of work-related injuries among construction workers--findings from the National Longitudinal Survey of Youth.

Dong, Xiuwen Sue; Wang, Xuanwen; Largay, Julie A; Sokas, Rosemary

2015-03-01

This study examined the relationship between work-related injuries and health outcomes among a cohort of blue-collar construction workers. Data were from the National Longitudinal Survey of Youth, 1979 cohort (NLSY79; n = 12,686). A range of health outcomes among blue-collar construction workers (n = 1,435) were measured when they turned age 40 (1998-2006) and stratified by these workers' prior work-related injury status between 1988 and 2000. Univariate and multivariate analyses were conducted to measure differences among subgroups. About 38% of the construction cohort reported injuries resulting in days away from work (DAFW); another 15% were injured but reported no DAFW (NDAFW). At age 40, an average of 10 years after injury, those with DAFW injury had worse self-reported general health and mental health, and more diagnosed conditions and functional limitations than those without injury. This difference was statistically significant after controlling for major demographics. Adverse health effects from occupational injury among construction workers persist longer than previously documented. © 2015 Wiley Periodicals, Inc.

Surveillance of construction worker injuries: the utility of trade-specific analysis.

Hunting, K L; Welch, L S; Nessel-Stephens, L; Anderson, J; Mawudeku, A

Construction is a dangerous industry, with high rates of both fatal and nonfatal injuries. To learn more about the causes of nonfatal construction worker injuries, and to identify injury cases for further work site-based investigations or prevention programs, we established an emergency department-based surveillance program in November 1990. This article describes circumstances of injury, diagnoses, and demographic characteristics of injured construction workers for 2,791 cases identified through mid-August, 1997. Lacerations and strains and sprains were the most frequent diagnoses; cutting and piercing objects were the leading causes of injury among all construction workers, followed by falls and overexertion. Because of the variety of work performed in this industry, more detailed injury descriptions, by trade, are most useful for thinking about injury prevention. To illustrate this, we profile injury patterns among workers from four specific trades: carpenters, electricians, plumbers, and ironworkers. Areas of concern highlighted by the trade-specific analyses include eye injuries among plumbers; falls from ladders among electricians and plumbers; slips, trips, and falls on the same level among ironworkers; electrical exposure among electricians; and, amputations among carpenters.

In 1998, the U.S. Geological Survey, in cooperation with the Sweetwater Authority, began a study to monitor water, air, and sediment at the Sweetwater and Loveland Reservoirs in San Diego County, California. The study includes regular sampling of water and air at Sweetwater Reservoir for chemical constituents, including volatile organic compounds (VOC), polynuclear aromatic hydrocarbons (PAH), pesticides, and major and trace elements. The purpose of this study is to monitor changes in contaminant composition and concentration during the construction and operation of State Route 125. To accomplish this, the study was divided into two phases. Phase One sampling (water years 1998–2004) determined baseline conditions for the detection frequency and the concentrations of target compounds in air and water. Phase Two sampling (starting water year 2005) continues at selected monitoring sites during and after construction of State Route 125 to assess the chemical impact this roadway alignment may have on water quality in the reservoir. Water samples were collected for VOCs and pesticides at Loveland Reservoir during Phase One and will be collected during Phase Two for comparison purposes. Air samples collected to monitor changes in VOCs, PAHs, and pesticides were analyzed by adapting methods used to analyze water samples. Bed-sediment samples have been and will be collected three times during the study; at the beginning of Phase One, at the start of Phase Two, and near the end of the study. In addition to the ongoing data collection, several special studies were initiated to assess the occurrence of specific chemicals of concern, such as trace metals, anthropogenic indicator compounds, and pharmaceuticals. This report describes the study design, and the sampling and analytical methods, and presents data from water and air samples collected during the fourth and fifth years of Phase One of the study (October 2001 to September 2003). Data collected during the first three years has been previously published. Three types of quality-control samples were used in this study: blanks, spikes, and replicates. Blanks and spikes are used to estimate result bias, and replicates are used to estimate result variability. Additionally, surrogate compounds were added at the laboratory to samples of VOCs, PAHs, pesticides, anthropogenic indicator compounds, and pharmaceuticals to monitor sample-specific performance of the analytical method.

Construction workers handle cement which has constituents to produce both irritant contact dermatitis and corrosive effects (from alkaline ingredients, such as lime) and sensitization, leading to allergic contact dermatitis (from ingredients, such as chromium). The present study has been carried out among unorganized construction workers to find the prevalence of skin problems. The present cross-sectional study was conducted in 92 construction workers of Ahmedabad and Vadodara. All the workers were subjected to clinical examination after collection of information regarding demographic characteristics, occupational characteristics and clinical history on a predesigned proforma. Of them, 47.8% had morbid skin conditions. Frictional callosities in palm were observed in 18 (19.6%) subjects while 4 (4.3%) subjects had contact dermatitis. Other conditions included dry, fissured and scaly skin, infectious skin lesion, tinea cruris, lesion and ulcers on hands and/or soles. The skin conditions were common in the age group of 20-25 years, males, those having ≥1 year exposure and those working for longer hours. Half of the workers not using personal protective equipment had reported skin-related symptoms.

Millions of U.S. workers are at risk for a work-related motor vehicle crash. Fatality data show that across all industries, motor vehicle crashes are consistently the leading cause of work-related fatalities. Of 43,025 work-related fatalities reported by BLS between 2003 and 2010, 10,202 were the result of single- or multiple-vehicle crashes of workers driving or riding in a vehicle on a public roadway, and 2,707 were pedestrian workers struck by a motor vehicle. During the same period, an additional 2,487 workers died in crashes that occurred off a public roadway or on industrial premises (BLS, 2013).

Concentrations of polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) were measured in 169 avian eggs. We analyzed randomly collected eggs of two species of piscivorous birds: Caspian tern (Sterna caspia) (n=78) and Forster's tern (Sterna forsteri) (n=76). We also analyzed fail-to-hatch eggs from two species protected under the Federal Endangered Species Act of 1973, that breed in the San Francisco Bay region: the piscivorous California Least tern (Sterna antillarum brownii) (n=11) and the omnivorous California Clapper rail (Rallus longirostris obsoletus) (n=4). San Francisco Bay eggs were collected annually for four years (2000-2003), and additional 20 eggs were collected and analyzed from Gray's Harbor, Washington in 2001. Geometric mean PBDE concentrations did not significantly differ in the three tern species, but concentrations in eggs from the fail to hatch California Clapper rail eggs were significantly lower than those found in the randomly collected tern eggs. Median concentrations of SigmaPBDEs in Caspian tern eggs for 2000-2003 were 2410, 4730, 3720 and 2880 ng/g lipid weight (lw), respectively, in Forster's terns 1820, 4380, 5460 and 3600 ng/g lw, respectively, and in California Least terns for 2001 and 2002 were 5060 and 5170 ng/g lw, respectively. In contrast, median SigmaPBDEs concentration in California Clapper rail eggs for 2001 was 379 ng/g lw. Five PBDEs were the major congeners found and decreased in the order BDE-47, -99, -100, -153, and -154. BDE-32, -28, -71, -66, -85, -183 were less prevalent, minor congeners, as was BDE-209, which was measured in a subset of samples. PBDE concentrations in bird eggs from San Francisco Bay were site related. There was no significant difference in PBDE concentrations in Caspian tern eggs from San Francisco Bay and Gray's Harbor, WA. Average PBDE concentrations in eggs did not significantly increase over the period 2000-2003.

This study tries to understand the relation between the reality of the nurse's everyday work and the construction process of this identity, using Agnes Heller's sociological theory of everyday life as the main reference. The possibilities of the worker's expression and fulfillment occur through objective and subjective elements of job reality which comes upon the worker as people who put order and tension in their everyday job; these job determinants imprint and produce impacts, giving sense to the work quality and constructing concrete possibilities to the worker to manifest him/herself as Whole being, guiding the construction of his/her identity.

To evaluate The Community Health Worker "promotor de salud" (CHW) model is evaluated as a tool for reducing eye injuries in Latino farm workers. In 2001, 786 workers on 34 farms were divided into three intervention blocks: (A) CHWs provided protective eyewear and training to farm workers; (B) CHWs provided eyewear but no training to farm workers; (C) eyewear was distributed to farm workers with no CHW present and no training. Pre- and post-intervention questionnaires demonstrated greater self-reported use of eyewear in all blocks after the intervention (P < 0.0001), with Block A showing the greatest change compared to B (P < 0.0001) and C (P = 0.03); this was supported by field observations. Block A showed the greatest improvement in knowledge on questions related to training content. CHWs were an effective tool to train farm workers in eye health and safety, improving the use of personal protective equipment and knowledge.
