The author investigates the effect of job insecurity and other job stressors on the mental health of steel workers. Levels of job stress and mental health were measured seven years before and seven months after the company at which they worked had gone into receivership, a method that can be described as a quasi‐experimental field study with a sample of blue‐collar non‐supervisory male workers. Two out of four job stressors were found to be at a lower level when the second wave of research took place. Regression analyses showed that the correlation between these job stressors and psychosomatic complaints is now lower than during the first wave but that they reach the former level when job insecurity is added. Job insecurity was mainly connected to an increase in psychosomatic complaints and in anxiety. Self‐esteem, depression, and irascibility showed no important relationship to job insecurity when the variables were controlled for mental health status before the onset of job insecurity. Social support, opportunities in the labor market, and duration of contract in the company are identified as moderating the relation between mental health and job insecurity. One conclusion is that positive health effects due to reduction in the stress level may be offset by acute job insecurity. Copyright © 2000 John Wiley & Sons, Ltd. 相似文献

Social capacity building for natural hazards is a topic increasingly gaining relevance not only for so-called developing countries but also for European welfare states which are continuously challenged by the social, economic and ecological impacts of natural hazards. Following an outline of recent governance changes with regard to natural hazards, we develop a heuristic model of social capacity building by taking into account a wide range of existing expertise from different fields of research. Particular attention is paid to social vulnerability and its assessment, as well as to risk communication and risk education as specific strategies of social capacity building. We propose to distinguish between interventionist and participatory approaches, thus enabling for a better understanding of existing practices of social capacity building as well as their particular strengths and weaknesses. By way of conclusion, we encourage more research on social capacity building for natural hazards in the European context which at present is highly diverse and, at least in parts, only poorly investigated. 相似文献

Impact of ocean acidification on escape performance of the king scallop, Pecten maximus, from Norway

The ongoing process of ocean acidification already affects marine life, and according to the concept of oxygen and capacity limitation of thermal tolerance, these effects may be intensified at the borders of the thermal tolerance window. We studied the effects of elevated CO2 concentrations on clapping performance and energy metabolism of the commercially important scallop Pecten maximus. Individuals were exposed for at least 30 days to 4 °C (winter) or to 10 °C (spring/summer) at either ambient (0.04 kPa, normocapnia) or predicted future PCO2 levels (0.11 kPa, hypercapnia). Cold-exposed (4 °C) groups revealed thermal stress exacerbated by PCO2 indicated by a high mortality overall and its increase from 55 % under normocapnia to 90 % under hypercapnia. We therefore excluded the 4 °C groups from further experimentation. Scallops at 10 °C showed impaired clapping performance following hypercapnic exposure. Force production was significantly reduced although the number of claps was unchanged between normocapnia- and hypercapnia-exposed scallops. The difference between maximal and resting metabolic rate (aerobic scope) of the hypercapnic scallops was significantly reduced compared with normocapnic animals, indicating a reduction in net aerobic scope. Our data confirm that ocean acidification narrows the thermal tolerance range of scallops resulting in elevated vulnerability to temperature extremes and impairs the animal’s performance capacity with potentially detrimental consequences for its fitness and survival in the ocean of tomorrow. 相似文献
