Influence of work history on entrepreneurial intentions in ‘prime age’ and ‘third age’: A preliminary study

This exploratory study investigates the relationship between an individual’s socialization into different professional and organizational cultures and their subsequent entrepreneurial intentions. Using age cohorts as a proxy for the duration of work-related socialization processes and changes in the business environment over time, the study proposes that the impact of work history is stronger in ‘third age’ (50—64 years) than in ‘prime age’ (20—49 years). The principal finding is that older individuals, those aged 50-plus, who have spent the majority of their career in ‘blue-collar’ industrial work are less inclined towards entrepreneurship than the working-age population in Western Finland generally. One reason is the perceived lack of support from important social contacts. Contrary to expectations, a work history in the public sector or small businesses does not seem to affect subsequent entrepreneurial intentions. Further research is required to provide a more fine-grained understanding of the impact of work history on entrepreneurial intentions.

A longitudinal qualitative study of the experience of working following treatment for gynaecological cancer

There are an increasing number of gynaecological cancer survivors for whom returning to work is a realistic outcome. There is little research to date specifically examining the return to work experience of survivors of gynaecological cancers. The aim of this study was to explore gynaecological cancer survivors' experience of work over a 1-year period post-treatment. A total of 55 gynaecological cancer survivors completed a semi-structured interview following completion of their treatment and of these 36 also completed a follow-up interview 12 months later. In total, 91 interviews were recorded and transcribed verbatim. Framework analysis of the transcripts was undertaken. Three super-ordinate themes were identified and these were labelled 'Meaning of work', 'Disclosure of cancer diagnosis' and 'Readjustment'. Overall, there were few changes in working patterns between the two interview points with the majority of women returning to the same role. Although a desire to make work-related changes was expressed at baseline, few women had initiated such changes 1-year post-treatment. Employees may experience difficulties due to residual symptoms, such as continuing fatigue, or as a result of unrealistic expectations about returning to full employment soon after treatment has completed. The results highlight the need for an intervention to support gynaecological cancer survivors to cope with long-term residual symptoms and manage expectations about returning to work.

S159 Do occupational asthmatics with small changes in PEF at work have less FEV1 decline than those with larger changes?

BackgroundThe significance of consistent small changes in PEF related to work, or records with diurnal variation within the normal range, are disputed. We related PEF changes at diagnosis to longitudinal...

Comparison of various airflow measurements in symptomatic textile workers

To investigate the poorly understood relationship between work-related respiratory symptoms, airway reactivity, across working shift change in forced expiratory volume in 1 s (FEV(1)) and work-related changes in serial peak expiratory flow (sPEF) measures in a group of textile workers. Fifty-three workers, 34 exposed to cotton dust and 19 to man-made fibre (MMF), were investigated using a standard respiratory questionnaire, sPEF, across-shift FEV(1) measurement and airway responsiveness. Thirty-four workers (64%) were male, and 9 workers (17%) had a >5% across-shift fall in FEV(1), and these falls were associated with the presence of work-related symptoms. Seven workers had a positive sPEF chart as judged by the software analysis (OASYS), although there was no relationship between work-related symptoms and sPEF. Six cotton workers (18%) and one MMF worker (5%) had airway hyperreactivity, which was associated strongly with work-related symptoms. Five of the 7 subjects with a positive sPEF had airway hyperreactivity compared with 12 of 46 with a negative sPEF. In this worker group, the presence of work-related respiratory symptoms was best associated with airway hyperresponsiveness and across-shift changes in FEV(1). While a positive sPEF chart was associated with increased airway responsiveness, it was not associated with work-related symptoms. sPEF measurements may not be the initial investigation of choice for such workers. As these findings also have relevance to developing evidence-based approaches to health surveillance, further work is needed to better define these relationships in other workers complaining of work-related respiratory symptoms.

Occupational nonasthmatic eosinophilic bronchitis

Occupational nonasthmatic eosinophilic bronchitis is characterized by the presence of chronic cough (lasting more than 3 weeks) that worsens at work and sputum eosinophilia (3% in the sputum). Sputum eosinophilia increases on exposure to the offending agent, spirometric parameters, which are normal and not significantly affected by exposure to the offending agent, absence of bronchial hyperresponsiveness to methacholine and adenosine when examined at work and away from work, and when other causes of chronic cough are ruled out. Examination of induced sputum should be part of the diagnostic algorithm for workers who complain of asthma-like symptoms in the workplace. Eosinophilic bronchitis should be regarded as an occupationally-induced condition when work-related changes in sputum samples are significant and reproducible.

Effects of office innovation on office workers' health and performance

The implementation of an innovative office concept (e.g. open-plan, flexible workplaces and a paperless office concept) on health and productivity among office workers was evaluated with questionnaires of 138 workers at baseline and 6 and 15 months afterwards. Work-related fatigue, general health, change in health status, upper extremity complaints and perceived productivity were outcomes. No short-term significant differences were found in most outcomes except for quantity of performed work (decrease from 96% to 92%, p = 0.008). In the long-term, no significant differences were found in most outcomes except for an increase in general health (p = 0.011) and a decrease in prevalences of upper extremity complaints (33% to 22%, p = 0.021). Perceived productivity increased significantly 15 months after the implementation. It is concluded that innovative office concepts had no or limited effects on work-related fatigue, health changes and productivity but some positive effects on workers' general health and upper extremity complaints in the long term. Office innovation is being administered often but up to now seldom evaluated on workers' health and productivity.

Work-Related Asthma in Automobile Spray Painters: Two Case Reports

This report describes two patients who had developed asthma after working as automobile painters with isocyanate-based aerosol paint for two years or over. In both patients asthma was confirmed using the standard diagnostic procedure. One of the subjects was atopic. One was ex-smoker and the other had never smoked. Neither had a family history of asthma. The symptoms occurred after workplace exposure lasting two years in one patient and three in the other. As both reported work-relatedness of the symptoms, they underwent serial peak expiratory flow rate (PEFR) measurement and bronchoprovocation testing. Significant work-related changes in PEFR diurnal variations and in non-specific bronchial hyperresponsiveness (NSBH) were observed in one patient, suggesting allergic occupational asthma (OA), while the other patient was diagnosed work-exacerbated asthma (WEA). Our data confirm that spray painting is an occupation with increased risk of respiratory impairment and asthma.

Application of metrics constructed from vibrotactile thresholds to the assessment of tactile sensory changes in the hands

Two tools for assessing tactile sensory disturbances in the hands have been constructed from mechanoreceptor-specific vibrotactile threshold shifts, and thresholds changes with time, and employed in a prospective study of forest workers (N=18). Statistically significant positive threshold shifts (i.e., reductions in sensitivity compared to the hands of healthy persons) were found in five hands at study inception (13.9%), and 15 hands at follow-up (41.7%). Four patterns of threshold shift could be identified, involving selectively the median and/or ulnar nerve pathways and/or end organs. Statistically significant positive threshold changes (i.e., reductions in sensitivity with time) were recorded in 69.4% of the hands over a five-year period, even though a majority of the workers remained symptom free. If the thresholds recorded from subjects not working with power tools are used to control for aging, lifestyle, and environmental factors during the five year period, then 40% of the remaining subjects are found to be experiencing work-related threshold changes in their hands. The ability of the threshold shift metric to predict the numbness reported by these subjects shows that it is closely associated with the tactile sensory changes occurring in their hands.

Occupational Asthma in Subjects Occupationally Exposed to Herbal and Fruit Tea Dust

We performed a cross-sectional study to detect occupational asthma (OA) in 63 subjects occupationally exposed to herbal and fruit tea dust and in 63 corresponding controls. The evaluation included a questionnaire, skin prick tests to workplace and common inhalant allergens, spirometry, and histamine challenge test. The evaluation of the work-relatedness of asthma in the exposed workers was based on serial peak expiratory flow rate (PEFR) measurements and bronchoprovocation tests. We found a higher prevalence of respiratory symptoms in the exposed workers, whereas spirometric parameters were significantly lower. The prevalence of sensitisation to allergens and of bronchial hyperresponsivenss (BHR) did not differ significantly between the groups. The prevalence of asthma was also similar in both groups (8.0 % vs. 6.4 %; P=0.540). Work-relatedness of symptoms was reported by all asthmatic tea workers and by no control with asthma. Significant work-related changes in PEFR diurnal variations and in non-specific BHR, suggesting allergic OA, were found in one tea worker with asthma (1.6 %). No specific workplace agent causing OA in the affected subject was identified. None of the tea workers with asthma met the criteria for medical case definition of the reactive airway dysfunction syndrome (RADS). Our data confirm workplace exposure to herbal and fruit tea dust as a risk factor for OA.

A Process and Outcomes Evaluation of the International AIDS Conference: Who Attends? Who Benefits Most?

The objective of the study was to conduct a process and outcomes evaluation of the International AIDS Conference (IAC). Reaction evaluation data are presented from a delegate survey distributed at the 2004 IAC held in Thailand. Input and output data from the Thailand IAC are compared to data from previous IACs to ascertain attendance and reaction trends, which delegates benefit most, and host country effects. Outcomes effectiveness data were collected via a survey and intercept interviews. Data suggest that the host country may significantly affect the number and quality of basic science IAC presentations, who attends, and who benefits most. Intended and executed HIV work-related behavior change was assessed under 9 classifications. Delegates who attended 1 previous IAC were more likely to report behavior changes than attendees who attended more than 1 previous IAC. The conference needs to be continually evaluated to elicit the required data to plan effective future IACs.

Job Loss, the Family, and Public Policy

SUMMARY Worker-family units in the U.S. have been impacted by significant work-related changes, including mass layoffs and involuntary job loss through shutdowns. Some post-WWII federal policies have been created to assist displaced workers adapt to job loss, thereby reducing stress in family relations. While these policies assisted dislocated workers to adjust to involuntary joblessness, there are still needs that exist for terminated workers, particularly for those individuals who desire long-term training, those worker-family units that are dramatically impactedincluding single parent families and family units where both partners have become joblessand in communities that are dependent on a single industry or have had multiple workforce reductions.

Community involvement and socialization among individuals with mental retardation

Mental retardation, a condition characterized by significantly lower than average intellectual ability and adaptive behavior deficits, currently affects between 2% and 3% of the population. Individuals with mental retardation experience many difficulties throughout their lives, with one such difficulty being that they have few opportunities for community involvement and often have few social relationships. To determine if increased community involvement and increased socialization are among the most common desires expressed by individuals with mental retardation, we conducted a study examining pre-existing data of 1348 individuals. The study focused on specific desires expressed by individuals with mental retardation—including, but not limited to, increased community involvement and increased socialization. Although these individuals expressed a wide variety of desires, they expressed a desire for increased community involvement most frequently. Individuals also frequently expressed a desire for increased socialization, change of residence, work-related changes, increased personal belongings, and increased personal activities. We discuss the importance of community involvement and socialization, the link between the two, interactions that could potentially exist among other expressed desires, and ways of increasing community involvement while addressing other desires that individuals with mental retardation expressed.

Vocational counseling for people with HIV: The client-focused considering work model

With increased efficacy of HIV antiviral medications and subsequent improvement in health status, many people with HIV face new decisions regarding work. The Client-Focused Model of Considering Work describes the interplay between four domains of influence (medical, financial/legal, psychosocial, and vocational). In each of these domains, persons with HIV can experience both pressures to make work related changes and barriers to making these changes. A nonlinear decision-making process is articulated in four phases. The authors discuss and contrast this model with other rehabilitation models, describe its implications for planning and delivery of rehabilitation services, and cite research results from a career counseling program based on the model.

Airborne Endotoxin and Its Relationship to Pulmonary Function among Workers in an Indian Jute Mill

Air samples from various processing areas of an Indian jute mill were examined for endotoxin. The authors assessed work-related respiratory symptoms and pulmonary function changes in the dust-exposed workers from the different processing areas using a standard questionnaire and spirometry. Endotoxin was estimated in water extract of jute dust from 3 milling areas, and in outside air, by the Limulus amebocyte lysate gel clot technique. The batching, spinning, and weaving areas of the jute mill showed endotoxin levels of 0.22-4.42 microg/m3, 0.04-1.47 microg/m3, and 0.01-0.07 microg/m3, respectively, values similar to those found in Indian cotton mills. Respiratory morbidities among the workers included typical byssinotic symptoms, along with acute changes in postshift forced expiratory volume in 1 s (FEV1.0) (31.8%). Results of this study demonstrated that increased exposure to bacterial endotoxin in airborne dust is related to byssinotic symptoms among Indian jute mill workers. Findings were similar to those reported previously for workers in the cotton, flax, and hemp industries.

Change Theory in CPE and HRD: Toward a Holistic View of Learning and Change in Work

The problem and the solution. Whereas human resource development, for the most part, addresses organizational levels of learning and change, continuing professional education focuses on these processes largely through the lens of individual practitioner learning and development. Each of these perspectives provides a helpful but incomplete notion of work-related learning and change.To increase their effectiveness, these fields need to be grounded in a more holistic understanding of workrelated learning and change and how it can be facilitated.

Assessment of Bronchial Responsiveness Following Exposure to Inhaled Occupational and Environmental Agents

Inhalation of a range of agents can result in airway inflammation and/or irritation. This may result in occupational asthma or reactive airways dysfunction syndrome. Reactive airways dysfunction syndrome follows a single large exposure to a chemical agent but is now frequently embraced under the wider term of irritant-induced asthma, a term that also includes asthma due to persistent, lower dose irritant exposures. Bronchial hyperresponsiveness is a hallmark of both occupational asthma and reactive airways dysfunction syndrome, although some patients with occupational asthma may occasionally have typical clinical features without increased bronchial hyperresponsiveness. Following removal of the causal agent in occupational asthma, bronchial hyperresponsiveness generally returns towards normal over a 2-year period, although some individuals demonstrate increased bronchial hyperresponsiveness for longer. Measurement of specific bronchial hyperresponsiveness to the primary causal agent in occupational asthma is used diagnostically but not for assessing prognosis. Bronchial hyperresponsiveness to inhaled methacholine can be measured across individual workshifts to assess work-related change. It may also be measured at the end of a work period when exposure has occurred, and compared with values following a period away from work. There have been no direct, systematic comparisons of changes in methacholine responsiveness in the diagnosis of occupational asthma compared with the more frequently used serial peak flow measurements. Patients with reactive airways dysfunction syndrome classically exhibit non-specific bronchial hyperresponsiveness, which can be readily measured by evaluating responses to inhaled methacholine. Bronchial hyperresponsiveness in reactive airways dysfunction syndrome can persist for many years after initial exposure and serial changes can be used to assess recovery and subsequent disability over time.

Desaceleración, crisis, reactivación y recesión industrial de la región Centro de México. Un largo ciclo de reestructuración del núcleo y la periferia

En este documento se analiza el ciclo de reestructuracion por el que ha transitado la industria manufacturera de la region Centro de Mexico en las tres ultimas decadas del siglo XX, a partir de una periodizacion que permite distinguir una fase de alto crecimiento con inestabilidad creciente que va de 1970 a 1980; un periodo de crisis y franca desindustrializacion que se extiende de 1980 a 1988; una etapa de reactivacion que comprende el quinquenio 1988-1993; y finalmente, un periodo recesivo que se extiende de 1993 a 1996. En cada fase se realiza un analisis comparado de los principales cambios productivos, laborales y territoriales experimentados por el nucleo urbano-industrial primario y por la periferia regional, a fin de identificar las industrias ganadoras y perdedoras, los cambios en la division regional del trabajo y en los niveles de concentracion territorial de la industria. La lectura global del ciclo permite identificar una notoria inestabilidad del crecimiento industrial, que alimenta las diferencias intraregionales e incide en una mayor complejidad territorial de la industria.

Current diagnostic methods for diisocyanate induced occupational asthma.

Diisocyanates are among the most frequent causes of occupational asthma in industrialized countries. Early diagnosis of diisocyanate asthma followed by prompt termination of chemical exposure can prevent chronic morbidity due to persistent asthma. The accurate diagnosis of diisocyanate asthma requires a systematic approach that combines information obtained from the occupational history, immunologic tests and physiologic studies. The advantages, limitations and validity of various methods and diagnostic guidelines utilized in the evaluation of diisocyanate asthma are reviewed. Recommended methods for evaluation of diisocyanates asthma are similar to approaches for other causative agents. Serologic assays of specific IgE are specific but insensitive diagnostic markers of diisocyanate asthma. If possible, workers should be evaluated, while at work, in order to demonstrate work-related changes in lung function associated with diisocyanate exposures. Specific bronchoprovocation challenge testing with diisocyanates, is reserved for situations where the diagnosis cannot be confirmed at work. Such tests can be performed safely but should be conducted exclusively at specialized centers by experienced personnel. Published diagnostic guidelines for occupational asthma are directly applicable to the evaluation of diisocyanate asthma.

What Prevents Professional Drivers from Following Physicians’ Cardiologic Advice?

Background: There is a scarcity of published studies of the effects of cardiac counselling among professional drivers (PD). Aims of the study were: (1) to examine explanatory variables for two classical ‘driver’ risk factors – body mass index (BMI), and smoking – and to analyse the interrelations among smoking cessation, losing weight and work-related life changes; (2) to assess the effectiveness of risk factor counselling after 6 months, and (3) to gain insight into possible discrepancies between PD perception of needed changes and compliance with the physician’s advice. Methods: There were 4 groups of male PD: 13 with ischemic heart disease, 12 hypertensives, 10 borderline hypertensives and 34 normotensives. Baseline cardiovascular risk factors as well as occupational and behavioral data were assessed via questionnaire. The counselling was aimed at smoking cessation, weight loss and promoting leisure-time physical activity. Qualitative methods were used to assess PD perceptions about the work environment and health promotion. Results: Baseline smoking intensity was best predicted by the total burden of occupational stress and number of smoking years. Baseline BMI was best predicted by long work hours behind the wheel, low availability of attachment outside work and low self-reported job strain. Self-initiated smoking cessation was best predicted by few smoking years, low coffee intake and admitting fear during driving. Physical activity was significantly increased after 6 months. Losing weight was associated with: quitting or diminishing smoking and making other, work-related, life changes. None of the heavy smokers decreased their daily number of cigarettes after 6 months, although expressing the need to do so in self-generated statements. Conclusions: Exposure to occupational stressors, mainly, long work hours and the concomitant denial of job strain, in combination with low availability of social attachment outside work, could contribute to maintenance of maladaptive behavior in PD. These findings could serve as a basis for designing standardized intervention trials and suggest that modification of the work environment, with participation of the drivers, is a needed component of such trials. Particular attention should be paid to the length and scheduling of work shifts.
