A five week stress management program for pregnant adolescents and adolescent mothers emphasizing deep muscle relaxation and cognitive control methods was pilot tested with 23 experimental and 12 control subjects. The experimental group demonstrated a significantly greater reduction in cognitive and affective manifestations of stress and an increased belief in their ability to deal with stress. While the differences between the groups did not reach statistical significance with respect to changes in overall stress levels or use of specific coping strategies, a consistent trend was demonstrated in the data for more positive changes in the experimental group. Recommendations were made for an expanded program, the inclusion of incentives, and the program's inclusion in the school schedule.  相似文献

The effects of day-sleep on the quality ofsleep are not restricted to the night-work period itself. Effects can be measured during night-sleep in the period following night-work. A study on these after-effects, using a self-report instrument to measure sleep quality, is described. A total of N=7O operators wcrc observed over five consecutive undisturbed nights after a working period of seven morning shifts (N= 35) and after a working period of seven night-shifts (N= 35). The quality of sleep during the third night after the night-shift period was still significantly worse than the third night after the rnorning-shift period. No differential (after-)effects were observed with respect to differences in sleep duration.  相似文献

School grades, family demographics and responses to the parental authority questionnaire were assessed in 240 eighth‐grade students in the southern, central and northern parts of Tehran, Iran's capital. The result showed that poorer families with traditional values had more authoritarian attitudes toward parenting than richer families with more modern values. In contrast to the studies conducted in East Asian societies, the current study found that authoritative parenting was the style associated with the highest academic outcome. Tests of mediation and moderation effects showed that the relation between parenting style and academic outcome was independent of sociocultural context.  相似文献

Suffering at work has become a major social phenomena. This situation has many causes: high performance enhancement, urgency seen as an obligation, pressure for results, but also fear, and the soaring of ‘the battle for places’ (la lutte des places). The psychopathological consequences of pressure at work are now well known: breakdowns, professional exhaustion, work addiction, burnout, harassment. Stress has become an ordinary tool for management. Employees cannot find a meaning to this context, nor can they identify the causes of their ill being or the reasons for the violence they endure. They confront an opaque and paradoxical power. Looking for solutions to the contradictions to which management has given rise without resolving, they become responsible for those difficulties and guilty of their own suffering. These are ‘innocent violences’ in so far as they are justified by an indisputable system of management.  相似文献

A deterministic model of BSE transmission is used to calculate the R(0) values for specific years of the BSE epidemics in the United Kingdom (UK), the Netherlands (NL), and Switzerland (CH). In all three countries, the R(0) values decreased below 1 after the introduction of a ban on feeding meat and bone meal (MBM) to ruminants around the 1990s. A variety of additional measures against BSE led to further decrease of R(0) to about 0.06 in the years around 1998. The calculated R(0) values were consistent with the observations made on the surveillance results for UK, but were partially conflicting with the surveillance results for NL and CH. There was evidence for a dependency of the BSE epidemic in NL and CH from an infection source not considered in the deterministic transmission model. Imports of MBM and feed components can be an explanation for this discrepancy, and the importance of imports for these observations is discussed.  相似文献

Starting with longitudinal data on two cohorts of women living in the Alpes-Maritimes in 1982 (a sample of 1,500 women in total) we try to establish the role of the spatial distribution of opportunities at a number of key stages in the life cycle: marriage, birth of first child, making professional use of qualifications, confrontation of a situation of professional risk and professional mobility during the years immediately following the completion of studies. The underlying hypothesis is that control of social location often depends on the control of spatial location.  相似文献

This article presents theoretical elements concerning the ‘nature versus culture’ confrontation as a particular aspect of the worldwide expansion of Western civilization. Several speculations are made concerning the philosophical foundations which have provided the base for the current political and economic mega-scenarios in the contemporary world. We turn our attention to the articulations of the concept of nature with the processes of mondialization of Western culture and with the history of universal culture. Finally, several considerations are made on the dynamics of economic processes on a world scale and projections on the impact of science and technology in the social and political frames that are taking place in the contemporary world.  相似文献

We characterize two different approaches to the idea of equality of opportunity. Roemer’s social ordering is motivated by a concern to compensate for the effects of certain (non-responsibility) factors on outcomes. Van de gaer’s social ordering is concerned with the equalization of the opportunity sets to which people have access. We show how different invariance axioms open the possibility to go beyond the simple additive specification implied by both rules. This offers scope for a broader interpretation of responsibility-sensitive egalitarianism.  相似文献
