Autonomic and affective responses to two different stress tasks were measured in 45 males and 74 females, categorized as repressive, true low-anxious, true high-anxious, and defensive high-anxious. Electrodermal activity (EDA) was used as a measure of sympathetic activity and the high frequency (HF) spectral component of heart rate variability as a measure of parasympathetic activity. Contrary to our predictions, reactivity of repressors did not differ from the reactivity of true low-anxious participants. The results draw attention to previous inconsistent findings within the literature on repressive coping style and autonomic nervous system dysregulation. It is suggested that future research could benefit from the use of more consistent operationalizations of the repressive coping construct and from comparing alternative measures of repressive coping within the same study. 相似文献

Psychological characteristics of elderly insomniacs 总被引:3,自引:0,他引:3

Sixty insomniacs, aged 60 years or over, fulfilling the DSM-IV criteria for primary insomnia, completed a set of questionnaires measuring psychological distress. These included the Sleep Impairment Index (SIM), the Symptom Check List 90-Revised (SCL-90-R), the Penn State Worry Questionnaire (PSWQ), the Toronto Alexithymia Scale-20 (TAS-20) and the Elders Life Stress Inventory (ELSI). The insomniacs were compared on these measures with two contrast groups, one of elderly good sleepers and one an elderly community sample. As norms were developed for the SCL-90-R and PSWQ, insomniacs were also contrasted with the norm groups on these measures. In general, the results indicated a higher level of psychological distress among insomniacs than among the good sleepers, while there were negligible differences between insomniacs and the community sample on most measures. Overall, elderly insomniacs scored higher on measures of worry compared with the other groups, followed by measures of somatization, obsessive-compulsion and depression. It is concluded that excessive worrying was the most characteristic feature of elderly insomniacs. 相似文献

Twenty-three empirical studies published between 1978 and 2000 on nonclinical children raised by lesbian mothers or gay fathers were reviewed (one Belgian/Dutch, one Danish, three British, and 18 North American). Twenty reported on offspring of lesbian mothers, and three on offspring of gay fathers. The studies encompassed a total of 615 offspring (age range 1.5-44 years) of lesbian mothers or gay fathers and 387 controls, who were assessed by psychological tests, questionnaires or interviews. Seven types of outcomes were found to be typical: emotional functioning, sexual preference, stigmatization, gender role behavior, behavioral adjustment, gender identity, and cognitive functioning. Children raised by lesbian mothers or gay fathers did not systematically differ from other children on any of the outcomes. The studies indicate that children raised by lesbian women do not experience adverse outcomes compared with other children. The same holds for children raised by gay men, but more studies should be done. 相似文献

Rationalism in political philosophy is the view that politics should be governed by moral principles and that those principles
can and should be justified independently of the situations and circumstances that make up political reality. This traditional
view of political philosophy implies that the meaning of right political action is determined by moral principles the rational authority of which derives from abstract philosophical reasoning,
not from the situations and circumstances that are the substance of political reality. In this essay I argue that rationalist
moralities must presuppose the understanding of particular situations and circumstances for their meaningful and correct interpretation.
This means, I argue, that the rightness of political judgement and action is immanent in particular situations, not in abstract
moralities. And this, I argue, suggests a shift from the traditional view of political society as the embodiment of abstract
principles, towards a view of political society as the embodiment of the activity of situational judgement. A society worth hoping for, then, is one in which we can live in the light of our understanding
of the situations and circumstances that are the substance of everyday life, rather than in the shadow of abstract moralities.
Such a society would be sensitive to the particularities and complexities of political reality, but at the same time it does
not succumb to moral relativism and skepticism. 相似文献

A natural one-year work-life intervention to improve occupational health and reduce absenteeism was designed as a field experiment. The intervention allowed the employees in the health care sector of a municipality to take up to five days of self-administered sick leave with full financial compensation up to four times a year. 165 employees in the intervention group and 100 employees in the control group filled out a questionnaire before and after the intervention. The result showed no evidence of misuse of this sick-leave option and some positive subjective health effects were found among those who used the option. Slight improvements were found in musculoskeletal problems and for cold/influenza. There were no effects on overall absenteeism. The question of the impact of local cultures on interventions to improve occupational health is also discussed. 相似文献

Five years after South Africa's first democratic elections in 1994, life satisfaction and happiness still reflect societal divides sowed by apartheid social engineering. The paper reports the indicators: life satisfaction, happiness and expectations for the future, from national surveys conducted between 1983 and 1999 for the South African Quality-of-Life Trends Project. Post-election euphoria, which saw all South Africans happy and satisfied with life for a brief moment in 1994, raises the question where the new set-level of subjective well-being will eventually come to rest. In 1999, in spite of some gains in living conditions, the level of life satisfaction of blacks has not risen above the mid-point and happiness is only slightly above the mid-point. Meanwhile, whites, who have forfeited their political dominance, continue to score above the mid-point on happiness and life satisfaction. The paper draws on the literature, particularly on quality-of-life trends in reunified Germany and paradoxical trends in African-American life satisfaction when discussing the dynamics underlying South African subjective well-being. It is argued that coping mechanisms may play an important role in determining levels of subjective well-being in the complex situation of South Africa. 相似文献

Responsiveness in prematurely and term-born infants was studied cross-sectionally in relation to maternal confidence. Orientation and arousal were measured in 140 prematurely (mean BW 1,398 g, GA 30.1 weeks) and 75 term-born infants (mean BW 3,613 g, GA 39.3 weeks) with the Neonatal Behavioral Assessment Scales. Mothers filled out the Maternal Confidence Questionnaire and a modified version of the Parenting Stress Index. Prematurely born infants had a significantly lower level of arousal than term-born neonates. Responsiveness was not associated with maternal confidence. Lower confidence was associated with primiparity in both groups of mothers. Multiparous mothers of prematurely born infants had significantly lower levels of confidence than multiparous mothers of term-born infants. Confidence was significantly associated with stress for mothers of prematurely and term-born infants, and may be focused in follow-up after giving birth. Prematurely born infants should be examined more thoroughly in aspects of arousal at the time of discharge. 相似文献

In this paper, I explore different ways of picturing language learning in philosophy, all of them inspired by Wittgenstein and all of them concerned about scepticism of meaning. I start by outlining the two pictures of children and language learning that emerge from Kripke’s famous reading of Wittgenstein. Next, I explore how social-pragmatic readings, represented by Meredith Williams, attempt to answer the sceptical anxieties. Finally, drawing somewhat on Stanley Cavell, I try to resolve these issues by investigating what characteristically happens to our view of language learning when we do philosophy. The focus throughout is on the relation between the individual (the learning child) and the community (usually represented by the parents), and how that relation is deformed when we operate with a certain philosophical notion of ground. 相似文献

To test the validity and reliability of self-assessed physical fitness samples included healthcare assistants working at a hospital (women=170, men=17), persons working with physically and mentally handicapped patients (women=530, men= 123), and two separate groups of healthcare students (a) women=91 and men=5 and (b) women=159 and men=10. Five components of physical fitness were self-assessed by Visual Analogue Scales with illustrations and verbal anchors for the extremes: aerobic fitness, muscle strength, endurance, flexibility, and balance. Convergent and divergent validity were evaluated by age-adjusted correlations stratified by sex with performance-based measures of physical fitness. Self-assessed aerobic fitness (r = .36 - .64) (women/men), muscle strength (r = .30 - .51), and flexibility (r = .36 - .31) showed moderate convergent validity. The divergent validity was satisfactory except for flexibility among men. The reliability was moderate to good (ICC = .62 - .80). Self-assessed aerobic fitness, muscle strength, and flexibility showed moderate construct validity and moderate to good reliability using visual analogues. 相似文献

Although Directive 2001/20/EC of the European Parliament and of Council of 4 April 2001 on the approximation of the laws regulations and administrative provisions of the Member States relating to the implementation of good clinical practice in the conduct of clinical trials on medicinal products for human use does not contain an exception for emergency situations, and requires the informed consent of a legal representative in all cases where research is conducted on legally competent individuals who are unable to give informed consent, in Poland, emergency research can be conducted without consent. Polish regulations on emergency research can hardly be treated as a result of intentional legislative policy. Our provisions arise from multiple and sophisticated interpretations of different regulations that govern medical experiments on human subjects and clinical trials. These interpretations can be summarized as follows: (1) There are two categories of medical experiments: therapeutic and non-therapeutic experiments. Emergency research without consent may be conducted in the category of therapeutic experiment only (therapeutic experiment consists of the introduction by the physician of new or only partially proven diagnostic, therapeutic or preventive methods in order to achieve direct benefit to the health of the patients, and it can be carried out when hitherto applied methods were ineffective or their effectiveness was insufficient). (2). Emergency research may be conducted without consent if there is a situation of great urgency in which the research subject's life is in danger and there is no possibility of obtaining immediate consent from the research subject him or herself, or from his or her legal representative or guardianship court, and the research subject has not refused to give consent for the participation in an emergency therapeutic experiment. The legal representative or guardianship court shall be provided with all the relevant information concerning subject's participation in an experiment as soon as possible. All projects of emergency research with intent to be done without the research subject's consent must be approved by an independent bioethics committee. Because these five requirements seem to provide insufficient protection for a subject's autonomy and rights it is necessary to add to them two other conditions: (1) the emergency research could not be conducted using other research participants capable of giving informed consent; and (2) informed consent for continued participation in the emergency research shall be obtained from either the participant him or herself or the legally authorized representative as soon as possible (requirement of obtaining deferred consent). A consolidated single Act that will govern all aspects of medical experiments on human subjects, including emergency research, should be prepared and enacted as soon as possible. 相似文献
