Computer-based typing and keypad skills raining outcomes of unemployed injection drug users in a therapeutic workplace.

The Therapeutic Workplace is an employment-based treatment for chronic drug misuse and unemployment. As a part of this intervention, participants are taught skills to perform data entry jobs and are paid based on attendance and productivity. In this study, computerized typing and keypad training programs were evaluated in recently detoxified HIV-positive injection drug users (n = 32) enrolled in the Therapeutic Workplace treatment program between October 2000 and September 2001. Results show that trainees can be taught fundamental typing and keypad skills in an average of 51.48 and 1.73h of training, respectively, administered over 17.91 and 12.59 weeks, respectively. Overall, the results demonstrate that adults with long histories of chronic unemployment and drug addiction can reliably acquire typing and keypad skills and do so over relatively short periods of time.

Development of a measure of personal web usage in the workplace.

This research develops a measurement model representing personal web usage activities (PWU) in the workplace. A series of activities are used to identify potential items and validate three personal web usage dimensions. These dimensions of activity include personal external business, personal external socializing, and personal external interest and research. First and second order confirmatory factor analyses are used to validate the instrument. The results recommend the use of personal web usage construct in both investigating the factors that lead to personal web usage in the workplace and in providing advice for practitioners of potential consequences of these personal web usage dimensions.

Perceptions of personal Web usage in the workplace: AQ-methodology approach.

An important aspect to managing Personal Web Usage (PWU) at the workplace lies in understanding and reshaping the perceptions of the users. The study contends that the outward manifestation of PWU behaviors at the workplace is but one consequence of the actors' attitudes which in turn are determinants of their ingrained beliefs. This study explores user perceptions about PWU using a web-based Q-methodology. Q-methodology used in this study is suitable for exploratory research, to obtain a deeper and first-hand understanding about the underlying phenomena about an under-explored concept. Twenty-five participants were asked to sort 38 statements according to their relative importance. The results uncover three distinct factors PWU: (1) cyber-bureaucrat, (2) cyber-humanist, and (3) cyber-adventurer. This indicates that PWU maybe a multidimensional construct instead of a uni-dimensional one as previously thought. The findings of this study can help managers understand, and shape the perceptions of the users rather than the outwardly manifested behaviors.

Aerosol sampling methods in workplace and ambient environments.

Aerosols are emitted into the workplace atmosphere and the ambient environment through a variety of processes. Aerosol particles are known to have significant effects on both human health and the ambient environment. For this reason, monitoring aerosol concentrations in the atmosphere by aerosol sampling is undertaken in workplace and ambient environments. A wide range of aerosol sampling methods using different collection mechanisms has been used for collecting representative aerosol samples using either a collecting or sensing medium. This paper shows the existing and commonly used aerosol sampling methods based on aerosol collection and real-time measurements. The method of choice for aerosol sampling will ultimately depend on a variety of factors, such as purpose of sampling, type of aerosol, analysis requirements, and available budget.

The setting of an occupational exposure limit for phosphamidon in the workplace--a Chinese approach.

This paper describes the approach of setting an occupational exposure limit for phosphamidon, an organophosphorus pesticide, in the workplace in China. Apart from a general review of the literature relating to various toxicological studies, special emphasis has been placed on the results of a systematic occupational health survey on the workers exposed to phosphamidon. As a result of the survey, together with the literature review, a 'maximum allowable concentration' (MAC) for phosphamidon in the air of workplace is suggested as 0.02 mg m-3 but on the condition that the route of skin entry be blocked effectively. In addition, based on the description of the standard-setting process in China, a comparison has been made to the current U.K. approach.

Meaningful workplace protection factor measurement: experimental protocols and data treatment.

Workplace performance measurement of respiratory protective equipment (RPE) is fundamental to the understanding of how well wearers are protected. It forms the basis for guidance on which the selection of appropriate equipment is based. However, the measurement of this performance is open to many sources of interference and inaccuracy, reducing the value and relevance of the results, and is most difficult for devices providing the highest levels of protection. In this paper, a method for critically assessing collected workplace protection factor (WPF) data is validated. This method rejects unreliable data, using criteria based on the detection limits of the analytical measurement system. An iterative approach is also described which arrives at a supportable estimate of given non-parametric percentiles of the distribution of measured WPFs [such as the fifth percentile, conventionally taken to be the assigned protection factor (APF)]. Further pragmatic criteria, based on a combination of experimental experience and consideration from first principles, are suggested as the basis for any future studies of RPE performance. These will maximize the chances of valid measurements being made, and also provide insight into the level of confidence which can be placed on any of the results. A consequence of these criteria is that typical working environments and measurement methods are incapable of generating WPF data which can be considered reliable.

Organizational instability and cardiovascular risk factors in white-collar employees: an analysis of correlates of structural instability of workplace organization on risk factors for coronary heart disease in a sample of 3,904 white collar employees in the Stockholm region.

BACKGROUND: The economic crisis in Sweden in the 1990s led to major reorganization at many workplaces, which appears to have had negative consequences for occupational and public health. METHODS: Psychosocial questionnaires and medical screening data for 3,904 white-collar employees in 15 major companies plus a large number of small-scale entrepreneurs in Stockholm were used. Subjects were part of a study of working conditions and cardiovascular risk factors (WOLF). Workplaces were categorized using interview data from managers and union representatives. Categories were compared regarding job strain, blood pressure, serum cholesterol, triglycerides, and fibrinogen among employees. RESULTS: The companies formed five categories: 'Stable', 'Changing/Growing', 'Threatened Private', 'Questioned Public', plus 'Small Firms'. Compared with the 'Stable' group, employees in 'Changing/Growing' companies had higher job strain (0.28 SD, p<0.001). In the 'Threatened Private' group, job strain (0.30 SD, p<0.001), cholesterol (0.18 mmol/l, p<0.05) and triglycerides (0.09 mmol/l, p<0.05) were elevated. The 'Questioned Public' group had higher cholesterol (0.22 mmol/l, p<0.01), triglycerides (0.10 mmol/l, p<0.01) and fibrinogen (0.13 mmol/l, p<0.05). In 'Small Firms', job strain (0.30 SD, p<0.001), cholesterol (0.28 mmol/l, p<0.001), triglycerides (0.14 mmol/l, p<0.001) and fibrinogen (0.19 mmol/l, p<0.001) were elevated. With the exception of lower systolic blood pressure (2.1 mmHg; p<0.05) in the 'Changing/Growing' category, there were no significant differences in blood pressure between the groups. CONCLUSION: In addition to traditional measures of organizational instability, such as downsizing, expansion in a favourable economic climate, appears to be adversely correlated with job strain and psychophysiology. The study also raises concerns about employees in small firms.

Evaluation of a workplace cardiovascular health promotion programme in the Republic of Ireland.

This paper describes a comprehensive evaluation of the organizational impact of a workplace health promotion programme, in the context of a framework devised by Nutbeam in 1998. The Happy Heart at Work programme, sponsored by the Irish Heart Foundation, has been in existence for 10 years and aims to promote a healthy lifestyle through specially devised modular materials. A postal census survey of 785 valid registered sites expressing any level of initial interest in the programme yielded a 40% response rate (n = 311). Of these, 194 (63%) were currently active and 114 were not. Active organizations were less likely to be Irish owned (54.5% versus 71.4%, p < 0.05), and more likely to operate in shifts (72.3% versus 51.1%, p < 0.05) or to have an occupational physician amongst the staff (36.9% versus 31%). Programme impact within active organizations, based on pre-defined Health Promoting Workplace parameters, was documented. There was agreement in the questionnaire responses that participating organizations promote a smoke-free environment (mean rating on five-point scale = 4.42), employee health and well-being (4.21) and good nutritional practice (4.11). Triangulation of research methods, including a telephone survey of gatekeepers from within organizations (n = 18), focus groups with participant employees (n = 42) and a review of the staff opinions of the facilitating organization on the programme, all showed strong concordance with respect to the strengths and weaknesses of Happy Heart at Work. The programme was felt to help improve employees' lifestyle habits and morale, as well as the company's public image. The main drawbacks of the programme were its relatively low profile, even in actively participating organizations, and the fact that it was not seen to be independently sustainable without intensive and ongoing support.

Evaluation of empowerment processes in a workplace health promotion intervention based on learning in Sweden.

The aim of this study was to evaluate a theory-based method for workplace health promotion (WHP) with regard to possible facilitation of empowerment processes. The intervention tool was the pedagogic method known as problem-based learning (PBL). The aim of the intervention was to promote empowerment and health among the employees. The intervention was implemented in three organizations within the public sector in Sweden, in a bottom-up approach. All employees, including management, in each organization, were offered the opportunity to participate (n = 113) and 87% (n = 97) participated. The intervention was implemented in 13 groups of six to eight participants who met once a week over a period of 4 months. The predetermined overall goal of the intervention was to promote employee health within the organizational setting. A facilitator in each group and a group-specific mutual agreement guided the intervention, as did the problem solving process. The participants set goals and developed strategies to reach their goals between the meetings. Thirty informants were interviewed in seven focus groups after the intervention about the intervention method and the process, following a semi-structured theme guide. The phenomenographic analysis resulted in six descriptive categories: reflection, awareness and insight, self-direction and self-management, group coherence, social support and actions. The results correspond to established theories of components of empowerment processes. The method initiated processes of change at organizational, workplace and individual levels as the participants examined their work situation, determined problems and initiated solutions. Social support and group coherence were expressed as essential in order to transform challenging strategies into action and goal realization. The findings indicate that systematic improvements of social support and group coherence among employees ought to be facilitated by the organization as a health-promoting arena. PBL appears to be a profitable and powerful instrument with the potential to enable empowerment.

Workplace air-conditioning and health services attendance among French middle-aged women: a prospective cohort study.

OBJECTIVES: To assess the relationship between type of ventilation in the workplace, health services attendance, and sickness absence among middle-aged women. METHODS: In a national sample of 920 professionally active women aged 49-65 yr from the SU.VI.MAX cohort, recruited from the general population in France, health services attendance and sickness absence were assessed prospectively during 1999. RESULTS: Being exposed to heating, ventilation, and air-conditioning (HVAC) systems in the workplace proved to be a risk factor for attendance at global and several specialist medical services. The adjusted odds ratio for otorhinolaryngologist attendance was 2.33 (95% CI = 1.35-4.04) in the HVAC group compared with the natural ventilation group, and 1.70 (1.13-2.58) for sickness absence. Dermatologist and global medical services attendance rates may also be higher in this group (P = 0.06 in both cases). CONCLUSIONS: Exposure to HVAC systems was a strong and significant risk factor for otorhinolaryngologist attendance and sickness absence. HVAC systems are prevalent in recent office buildings and have been shown to be associated with several adverse health effects in terms of morbidity and mortality. From a public-health perspective, our results outline the need for a quantitative assessment of the health impact of ventilation systems, taking into account the possible loss of production that exists in addition to the direct costs of medical services use.

Nitrite adulteration of workplace urine drug-testing specimens. I. Sources and associated concentrations of nitrite in urine and distinction between natural sources and adulteration.

The active ingredient in the commercial workplace urine drug-testing adulterant, Klear, was previously determined to be nitrite ion. Nitrite adulteration compromises the confirmation of some drugs, notably the marijuana metabolite. A previously reported bisulfite step overcomes some nitrite adulteration, but it cannot do so in every case, which leaves the laboratory to report the specimen as not suitable for testing. Unlike many other adulterants, nitrite is found in normal urine at low concentrations. In order to defend a report of nitrite adulteration, it is necessary to provide evidence that the amount of nitrite in a workplace urine specimen could not arise by normal means. The objectives of this study were to identify all sources of nitrite in urine and the range of concentrations associated with these sources and to determine if nitrite adulteration can be supported based upon a quantitative result. The scientific literature was reviewed for internal and external sources of nitrite and their concentration ranges and are reported. The following specimens were obtained and nitrite concentrations measured by a spectrophotometric method: clinical specimens nitrite positive by test strip (< 15 micrograms/mL); specimens culture positive for nitrate-reducing microorganisms (< 36 micrograms/mL); specimens from patients on medications that may metabolize to nitrite (< 6 micrograms/mL); and drug-test specimens, both negative (< 130 micrograms/mL) and others that appeared to be adulterated with nitrite (range 1910-12,200 micrograms/mL, mean 5910). The literature and the nitrite measurements of this study indicate a substantial difference between concentrations from natural sources compared with adulteration. A quantitative measurement of nitrite by a well-structured assay can provide scientifically valid and forensically defensible proof of adulteration with a nitrite-containing substance.

Alternative specimens for workplace drug testing.

Recent advances in analytical techniques have enabled the detection of drugs and drug metabolites in alternative biological specimens for the purposes of workplace testing. A wide variety of specimens are available, each providing valuable information concerning prior or current drug use. The present focus is on oral fluid (saliva), hair, and sweat. An extensive evaluation by the Division of Workplace Programs of the Department of Health and Human Services is underway to determine the utility of these specimens in federally regulated programs. In future years, the testing of alternative specimens will expand our ability to understand the patterns of drug use and will become routine in all areas of forensic toxicology.

Is atopy and smoking important in the workplace?

The relationship between the respiratory system and the environment involves a complex dynamic interaction of genetic susceptibility, host defence and toxicity. The chance of an individual developing a respiratory disease is dependent on genetic susceptibility and subsequent hereditary risk factors, life-style risk factors and the amount and nature of the exposure that may be encountered in the working environment. Atopic status is an important pre-existing risk that a worker may bring to the workplace (occupational asthma/rhinitis to high molecular weight agents). Smoking is an avoidable additional risk for certain occupational diseases (occupational asthma/bronchitis/cancer) while it can be protective in other circumstances (allergic alvcolitis). More controversially, smoking in some workers may put at increased risk the health of colleagues (passive smoking). This article attempts to clarify the issues surrounding the interaction of atopy, smoking and the workplace.

An exploratory workplace study to investigate the perceived value of continuous low-level heatwrap therapy in manual workers.

BACKGROUND: Between 60 and 80% of the population in industrialized countries experience low back pain at some time in their lives. The physical demands of work, i.e. manual handling, lifting, bending, twisting, awkward postures and whole body vibration are associated with low back symptoms. This study was undertaken to investigate the benefits of a new form of continuous low-level heatwrap therapy available for the symptomatic relief of acute low back pain in the workplace. METHODS: The subjects were recruited to the study upon their visit to the occupational health doctor after being diagnosed with acute low back pain. RESULTS: The study results show that use of the heatwrap therapy significantly reduced pain intensity and impact of pain on everyday activities. The results of the study were further extrapolated to show potential cost reduction benefits of using this heatwrap therapy in the workplace.

Low back pain interventions at the workplace: a systematic literature review.

OBJECTIVE: To assess the effect of controlled workplace interventions on low back pain (LBP) through a review of controlled studies. The rising costs of employees with LBP have resulted in an abundance of offers to society and organizations of interventions to prevent and/or treat the problem. Little is known of the effect of the different interventions. METHODS: A systematic literature search based on the inclusion criteria: controlled trial, work setting and assessment of at least one of the four main outcome measures: sick leave; costs; new episodes of LBP; and pain. Effect of the interventions was reported for the four main outcome measures. RESULTS: Thirty-one publications from 28 interventions were found to comply with the inclusion criteria. Exercise interventions to prevent LBP among employees and interventions to treat employees with LBP have documented an effect on sick leave, costs and new episodes of LBP. Multidisciplinary interventions have documented an effect on the level of pain. CONCLUSIONS: The results show that there is good reason to be careful when considering interventions aiming to prevent LBP among employees. Of all the workplace interventions only exercise and the comprehensive multidisciplinary and treatment interventions have a documented effect on LBP. There is a need for studies employing good methodology.

Assessing the evidence submitted in the development of a workplace smoking regulation: the case of Maryland.

OBJECTIVE: This study compared the characteristics of the basic science, biomedical, and socioeconomic literature submitted in 1993-1994 by supporters and opponents of the proposed workplace regulation of tobacco smoke developed by the Maryland Occupational Safety and Health (MOSH) Advisory Board. METHODS: The authors retrospectively analyzed 544 written publications submitted to the MOSH Advisory Board regarding the proposed workplace regulation of tobacco smoke. Outcome measures included the type and year of publication and, for journal articles, the journal's peer review policy and impact factor. RESULTS: Supporters of regulation submitted fewer documents (n = 164) than opponents (n = 380). Supporters of regulation submitted a lower proportion of conference proceedings and a higher proportion of government reports. The publications submitted to the regulators by the supporters of regulation were more recently published than the materials submitted by opponents. Journal articles represented more than half of the publications submitted; most were peer-reviewed. Supporters of regulation submitted articles from journals with higher impact factors (median impact factor 2.78) than did opponents of regulation (median 1.66; p = 0.0005), and articles that were published more recently (median year of publication 1990) than those submitted by opponents (median 1989; p = 0.0001). CONCLUSIONS: Public health advocates should highlight the scientific evidence base that supports tobacco control regulations. Public health advocates should encourage and support regulatory officials' use of the criteria of peer review, impact factor, and date of publication to prioritize their review of submitted documents in order to base policy on the best available evidence.

The inclusive workplace: an ecosystems approach to diversity management.

This article's main argument is that organizations need to expand their notion of diversity to include not only the organization itself, but also the larger systems that constitute its environment. The concept of "the inclusive workplace," introduced here, refers to a work organization that is not only accepting and using the diversity of its own work force, but also is active in the community, participates in state and federal programs to include working poor people, and collaborates across cultural and national boundaries with a focus on global mutual interests. Using an ecosystems perspective, the article outlines a value-based model and a practice-based model of the inclusive workplace as they pertain to the different organizational levels, from the micro to the macro. Finally, implications for the social work profession are drawn with specific case examples for each system level.
