Methods A cross-sectional epidemiological study was conducted in 452 workers from a thermal power plant in China. Extrinsic effort, occupational reward, and over-commitment were measured. Hypertensive patients were defined by three phases of screening, reexamination, and final diagnosis. β2-AR genotypes and allele frequencies at amino acid positions 16 （β2-AR-16： Arg→Gly） and 27 （β2-AR-27： Gln→Glu） were identified by PCR-RFLE Results Job stress was related with the prevalence of hypertension in males （P〈0.05）, whereas no significant relationship was found in females （P〉0.05）. Differences in genotypes and allele frequencies of the β2-AR-16 were statistically significant between the hypertension and control groups （P〈0.05）, whereas those of β2-AR-27 were not （P〉0.05）. The prevalence of hypertension was higher in individuals carrying Gly16 allele than in those carrying Arg16 allele of the high job stress group （P〈0.01 or 0.05）. Conclusion High job stress and polymorphism of β2-AR-16 have an interactive effect on the prevalence of hypertension in male workers.展开更多

Data were collected from May to December 2020. Research instruments with good internal consistency reliability ranged from 0.83 to 0.91 including the Job Stress Scale and the Thai version of the Job Content Questionnaire(TJCQ). Descriptive statistics and a structural equation model were used for data analysis.Results: Job demands were the strongest predictor of job stress. At the theoretical level, high job control plays a crucial role in directly reducing job stress. However, the present research provides contrary evidence to the theoretical predictions. When nurse-midwives perceive high job control, they perceive pressure to meet the expectations of their supervisors and colleagues. Therefore, high job control can contribute to job stress. Likewise, job suppor t had an indirect effect on job stress among nurse-midwives through job control. The modified model fitted the empirical data(χ^(2) = 57.76, df = 22, CMIN/df = 2.62, goodness of fit(GFI) =0.96, adjusted goodness of fit(AGFI) =0.91, comparative fit index(CFI) = 0.95, and root mean square error of approximation(RMSEA) = 0.07). The effects of job demands, job control, and job suppor t on job stress among Thai nurse-midwives can explain 67% of the model’s total variance for job stress.Conclusions: Nurse-midwives who encounter high job demands and less control over their work control suffer from job stress. Job support does not directly affect nurse-midwives’ job stress but influences it through perceived job control. Strategies to decrease job stress among Thai nurse-midwives should focus on how to balance job demands, and enhance job control, and job suppor t.展开更多

On this basis, a sample of 100 employees working in Guilan Education Office was used and research hypotheses were examined by job stress, life orientation and cognitive emotion regulation questionnaires. The results of this study indicate that job stress has a significant relationship with life orientation (-0.32), self-blame (0.25), rumination (-0.36), positive refocusing (0.25), positive refocusing on program (-0.21), positive reappraisal (-0.28), catastrophizing (-0.39) and other blames (-0.25). Furthermore, life orientation and cognitive regulation could explain 22% variances in respondents’ job stress. This finding indicates that more positive life orientation and subsequent decrease of emotion-regulation-related disorders will lead to less job stress.展开更多

The stress of human resources is directly related with work performance, and as such, should be managed to improve work performance. This study aims to perform a comparative analysis of job stress levels after a survey on the job stress of field managers and workers. Through the analysis, it is found that the stress levels of field managers are different from those of the workers and construction field managers and workers get job stress scores less than average scores of Korean male workers. In addition, different personal factors affect the field managers and the workers differently. Therefore, understanding by which factor the other parties become stressed is expected to improve efficiency in the management of human resources.展开更多

This study aimed to understand how workplace stressors affect job satisfaction among biologics development professionals. A cross-sectional survey was conducted at a biologics development organization. Multiple linear regression analysis was performed using years of experience, ambiguity, job conflict, perceived control, social support, job demands, self-esteem, and self-rated workplace stress as independent variables and job satisfaction as dependent variable (response). The regression model indicated that the workplace stressors and their two-level interactions significantly predicted employees’ job satisfaction, which explained 89% of the variance in level of job satisfaction (R2 = 0.89, F(17, 16) = 7.251, p = 0.0001). The interaction between perceived control and job demand and interaction between self-rated stress and job conflict had the biggest effect size on job satisfaction. This model was further used in Monte Carlo simulation to predict the outcome of job satisfaction under different work conditions. The findings will help the management to develop strategies to improve employee job satisfaction.展开更多

This can lead to workaholism and may result in stress and job burnout. The main objective of the current study is to examine the relationship of workaholism with stress and job burnout of elementary school teachers in Zahedan. This is a descriptive-correlational study. The sample includes 350 elementary school teachers in Zahedan whom are selected through applying stratified random sampling method and are examined using questionnaires on workaholism, occupational stress, and job burnout. To analyze the obtained data, correlation coefficient and simultaneous multiple regression analysis are applied using SPSS21. Teachers’ mean scores on workaholism, stress and job burnout are higher than the considered theoretical mean. Workaholism and its components (feeling of being driven to work, work involvement, and work enjoyment) are significantly and positively related to job burnout and occupational stress (p ). The results of simultaneous multiple regression analysis indicate that components of workaholism can predict teachers’ occupational stress and job burnout (p ). Considering the results, holding training courses for teachers to become familiar with the phenomena of workaholism, stress, and job burnout, individual and organizational outcomes, methods of dealing with them and managing them effectively is highly recommended.展开更多

The results showed that the germination energy, germination rate, germination index, root and seedling lengths, root and seedling diameters, root and seedling fresh masses, root and seedling dry masses, and seedling relative water content (RWC) decreased with the decrease of the osmotic potential of PEG 6000 solution. The contents of hydrogen peroxide (H2O2), malondialdehyde (MDA), and proline in seedling increased with the decrease of the osmotic potential of PEG 6000 solution. The activities of peroxidase (POD), catalase (CAT), ascorbate peroxidase (APX), and glutathione reductase (GR) in seedling increased and then decreased with the decrease of osmotic potential of PEG 6000 solution. -0.1 MPa was the optimal osmotic potential of PEG 6000 solution simulated drought stress at germination stage for Job’s tears. The proline content and activities of POD and CAT were important mechanisms for the maintenance of drought resistance in Job’s tears seedling.展开更多

Negative consequences of job demands were widely discussed throughout the literature like;poor quality of care, poor health, burnout, greater intent to leave and lower level of job satisfaction. Job dissatisfaction among nurses also has been discussed exhaustively in the literature in regards to its negative outcomes represented by burnout, absenteeism, turnover, greater intent to leave and finally leaving nursing profession. Purpose: The purpose of this study was to examine literature discussing job demands in nursing profession and its associated factors among nurses, and to provide direction as to where research needs to continue to explore and develop evidence in this area. Results: Results showed that job demands are the most influential stressor in nursing profession that associated strongly with many negative consequences on the profession in general and on the nurses on particular. Conclusion: The results supported that job demand is unavoidable stressor that leads to many negative consequences and connects directly to job dissatisfaction. Therefore, there is a need to search for alleviating factors that decrease nursing stressor, its consequences and buffer the correlation between job demand and job satisfaction.展开更多
