Is occupational stress associated with work engagement ?

The occupational stress is associated with dissatisfaction, excessive demand at work and personal factors. Those factors can reduce work performance and can predispose workers to various diseases. Workers' health may be protected if there is encouragement to face challenges, which may lessen the impact on psychological and somatic stress and thus have greater personal and professional satisfaction. The aim of this study was to evaluate the association between occupational stress and work engagement. Participated in this study 457 male and female workers of a metallurgical industry. Subjects answered personal data, and the Job Stress Scale and Utrecht Work Engagement Scale were applied. Results showed an association between occupational stress and work engagement (P=0,001). The way the individual deals with his frustrations, or rather the work engagement, is associated with the occupational stress.     

Productivity of highly skilled immigrants: economists in the postwar period

Prior work finds declining immigrant quality in the postwar period that is linked to source-country and skill-composition changes associated with the 1965 Immigration Act. This paper uses a unique panel of foreign- and native-born American Economic Association members to show that the highly skilled experienced a similar shift away from European migrants toward those from Asia. However, the findings do not indicate that this change in source-country composition has been accompanied by a decline in quality; rather, the most recent cohorts of foreign-born economists appear to be more productive than their native counterparts.

The influence of the tasks characteristics in physical performance and psychosocial aspects of workers

The work and life conditions have influence on the health and life quality of workers. Physically active persons can demonstrate a life style that are and affect the physical performance, psychosocial aspects and work capacity. The purpose of this study was to investigate the physical activity level and work capacity in different tasks characteristics, one with more physical exertion and other with more cognitive exertion. A total of 193 workers from an institution of higher education and 457 workers from a metallurgical industry participated in the current study. All participants completed the International Physical Activity Questionnaire (IPAQ-short) and Work Ability Index (WAI). The results indicated that both groups were classified as having high level of physical activity while only few of them were considered sedentary (less than 27%). However, the group of metallurgical workers had greater indices (82%) than the workers from higher education institution (74%). Overall, the workers reported their work ability as moderate to excellent, suggesting that overall they are satisfied with their working and health conditions. It can be concluded that even though workers performed tasks with different demands (cognitive versus physical), they demonstrated similar level of physical activity as well as work ability.
