    Opis:
    Objective: One of the practical models for assessment of stressful working conditions due to job strain is "job demand and control" or Karasek's job strain model. This model explains how adverse physical and psychological effects including cardiovascular disease risk factors can be established due to high work demand. The aim was to investigate how certain cardiovascular risk factors including body mass index (BMI), heart rate, blood pressure, serum total cholesterol levels, and cigarette smoking are associated with job demand and control in workers. Materials and Methods: In this cohort study, 500 subjects completed "job demand and control" questionnaires. Factor analysis method was used in order to specify the most important "job demand and control" questions. Health check-up records of the workers were applied to extract data about cardiovascular disease risk factors. Ultimately, hypothesis testing, based on Eta, was used to assess the relationship between separated working groups and cardiovascular risk factors (hypertension and serum total cholesterol level). Results: A significant relationship was found between the job demand-control model and cardiovascular risk factors. In terms of chisquared test results, the highest value was assessed for heart rate (Chi² = 145.078). The corresponding results for smoking and BMI were Chi² = 85.652 and Chi² = 30.941, respectively. Subsequently, Eta result for total cholesterol was 0.469, followed by hypertension equaling 0.684. Moreover, there was a significant difference between cardiovascular risk factors and job demand-control profiles among different working groups including the operational group, repairing group and servicing group. Conclusion: Job control and demand are significantly related to heart disease risk factors including hypertension, hyperlipidemia, and cigarette smoking.

    Opis:
    Objectives: This paper aims to assess the relationship between the determinants of the psychosocial work environment, as expressed in terms of JDC or ERI models, and all-cause mortality in older individuals. Materials and Methods: The baseline study was conducted on a cohort comprising a random sample of 65-year-old community-dwelling citizens of Kraków, Poland. All of the 727 participants (410 women, 317 men) were interviewed in their households in the period between 2001 and 2003; a structured questionnaire was used regarding their occupational activity history, which included indexes measuring particular dimensions of their psychosocial work environment based on Karasek's Job Demand-Control model and Siegrist's Effort-Reward Imbalance model, as well as health-related quality of life and demographic data. Mortality was ascertained by monitoring City Vital Records for 7 years. Analyses were conducted separately for men and women, with the multivariate Cox proportional hazard model. Results: During a 7-year follow-up period, 59 participants (8.1%) died, including 21 women (5.1% of total women) and 38 men (12%) (p < 0.05). Significant differences in the number of deaths occurred regarding disproportion between physical demands and control in men: those with low physical demands and low control died three times more often than those with high control, regardless of the level of demands. The multivariate Cox proportional hazard model showed that significantly higher risk of death was observed only in men with low physical demands and low control, compared to those with low physical demands and high control (Exp(B) = 4.65, 95% CI: 1.64-13.2). Conclusions: Observed differences in mortality patterns are similar to the patterns of relationships observed in health-related quality of life (HRQoL) level at the beginning of old age; however, the relationship between efforts and rewards or demands and control and mortality was not fully confirmed.

    Opis:
    Objectives Over the past decade, there has been a markedly growing interest in issues involving work-related stress in Europe. In Italy, according to Eurofound, research has demonstrated high levels of stress in the banking sector. With this in mind, a study was conducted to evaluate the peculiarities of hindrance and challenge stressors, and their links with recovery in the Italian banking population. Material and Methods The health and safety managers of a major Italian banking group were contacted and invited to participate in a stress assessment procedure, not only for research purposes but also to help them fulfill their obligations with regard to work-related stress. In total, 6588 bank workers took part in the study (57.5% males and 42.5% females) in 2012–2018. Work-related stress was measured with the Stress Questionnaire (SQ) that assesses several psychosocial working variables. Recovery was measured using a scale based on the SQ. The analysis and tabulation of the study results were performed using the Statistical Package for Social Sciences (SPSS). Results The results have demonstrated that female respondents lack more job control and colleagues’ support as compared to male respondents. Employees aged > 50 lack their supervisors’ support while employees with the shortest job seniority experience the greatest role ambiguity, as well as the lack of job control and colleagues’ support. The results of hierarchical regression analysis have demonstrated that the lack of colleagues and supervisors’ support, as well as job demands and job control, contribute to explaining the recovery experience. The greatest contribution to the explained variance could be attributed to job demands and the lack of colleagues’ support. Conclusions This study has demonstrated an important contribution of the so-called traditional stressors to predicting recovery for the banking population in Italy. These findings suggest that banks should adopt corporate policies containing activities for the prevention of and protection against stress, with a more general objective of improving the mental health of their workers.

    Opis:
    Aim. The objective of this study was to test the psychometric properties of selected scales, namely, Decision Latitude, Psychological Job Demand, Social Support and Job Insecurity, from the Polish version of Karasek’s 29-item Job Content Questionnaire (JCQ). Method. The study covered 2626 workers from a wide range of occupations. Estimation of internal consistency with Cronbach’s α, and both exploratory factor analysis (with principal axis method) and confirmatory factor analysis were the main statistical methods. Predictive validity was assessed by regressing the outcomes of JCQ scales on the outcomes of Goldberg and Williams’s General Health Questionnaire. Results. The internal consistency of the scales was satisfactory, ranging from .60 to .85. The 4-dimensional structure of the measured version was generally confirmed; the 4 dimensions being Decision Latitude; Psychological Job Demands and Job Insecurity merged into 1 factor; Co-workers’ Social Support; and Supervisors’ Social Support. Fit indexes for this model were satisfactory, it was also proved that this model predicted mental health. Conclusions. The Polish version of Karasek’s 29-item JCQ has satisfactory psychometric properties; it is a short, easy method for assessing psychosocial work conditions.

    Opis:
    Here we discuss a multi-product lot-sizing problem for a job shop controlled with a heijunka box. Demand is considered as a random variable with constant variation which must be absorbed somehow by the manufacturing system, either by increased inventory or by flexibility in the production. When a heijunka concept (production leveling) is used, fluctuations in customer orders are not transferred directly to the manufacturing system allowing for a smoother production and better production capacity utilization. The problem rather is to determine a tradeoff between the variability in the production line capacity requirement and the inventory level.

    Opis:
    Work stress or job-strain and iso-strain are perceived when there is a conflict between the demands placed on a person and their resources to cope with them. They have negative effects on worker health, and organizational productivity and performance. Our study consists of evaluating work stress and its components. 102 workers of different functions (senior managers, supervisors, technicians and executing workers) volunteered and were invited to complete anonymously the Karasek questionnaire (JCQ). The analysis of the results showed a significant prevalence of iso-strain and job-strain. Thus, low decision latitude and high psychological demands are the most widespread stress factors. These results show the need to disseminate information and prevention programs against work stress to managers and staff to ensure the effective performance of a company.

    Opis:
    Целью исследования является выявление взаимосвязи уровня развития субъектности российских менеджеров и оценки их социально-профессиональной востребованности, которая выступает в качестве субъективного критерия их профессионального благополучия и определяется как метасистема отношений личности к себе как к значимому для других профессионалу. Полученная регрессионная модель (R2 = 0,523) показала, что пре- дикторами высокого уровня профессиональной востребованности руководителей являются такие атрибуты субъектности как сформированные навыки самоуправления и высокий уровень активности личности. Также было установлено, что по сравнению с рядовыми сотрудниками менеджеры демонстрируют тенденцию к более частому использованию объектных моделей поведения. Рассматривается роль субъектности как психологического ресурса сохранения и поддержания профессионального благополучия; представлены направления дальнейших исследований.
    Celem badania było ustalenie związku pomiędzy poziomem rozwoju podmiotowości menedżerów rosyjskich a oceną przeżywania subiektywnego znaczenia wykonywanego zawodu, które występuje jako subiektywne kryterium dobrostanu zawodowego i które określone zostało jako układ nadrzędny w strukturze postaw osobowości wobec siebie w znaczeniu ważnego dla innych fachowca. Otrzymany model regresji (R2 = 0,523) pokazuje, że predyktorami wysokiego poziomu przeżywania subiektywnego znaczenia wykonywanego zawodu wśród kierowników są następujące atrybuty podmiotowości: ukształtowane nawyki kierowania sobą oraz wysoki poziom aktywności osobowości. Udowodniono, że menedżerowie w odróżnieniu od innych szeregowych pracowników częściej wykazują tendencję do przedmiotowych modeli zachowań. Analizowana jest rola podmiotowości jako jednego z zasobów psychicznych w podtrzymywaniu i wspieraniu dobrostanu zawodowego; przedstawiono kierunku dalszych badań w tym zakresie.
    The study addresses the improving of job-related well-being among Russian managers and analyzes the role of agency (“subjectivity”) in this process. As a criterion of occupational well-being is considered a self-assessment of the level of professional demand which is defined as meta-system of person’s subjective attitudes to him/herself as significant professional for others. We received the stepwise linear regression model according which advanced self-management skills and high level of activity have statistically reliable influence on general index of managers’ professional demand (R2 = 0,523). It was also found that managers tended to move to the more frequent use of the object-oriented behaviors than employees. The significance of focus on agency as one of the personal resources for occupational well-being promotion and the areas of future research are discussed.
