To what extent are gerontological issues addressed in the marital and family literature? In answering this question, the authors conducted a content analysis of 873 articles published in the Journal of Marital Family Therapy, Family Process, Family Systems Medicine, and the Journal of Family Psychology during an 8-year period beginning in 1986. Only 3.2% (n = 28) of these articles contained explicit emphasis on aging issues and later life family concerns. Furthermore, there was no significant trend in the number of gerontologically focused articles published during this period. The paper describes the content of the 28 aging-focused articles, including the types of presenting problems mentioned, the relational contexts of these problems, and the types of family therapy theories represented. Included in the content analysis were the proceedings of the annual national conferences of the American Association of Marital and Family Therapy from 1986 to 1993. Only 2.3% (n = 37) of the regular conference sessions had an explicit aging focus, as did 1 of the 29 plenary sessions and 1 of the 40 Master Series® sessions. Used as a gauge of gerontological interest and awareness of late life issues, the implication of these findings is that the family therapy community is still engaged in “comming of age.” 相似文献

The ways in which adolescents conceptualise families is not well understood. In this study perceptions of families by 232 adolescents were examined using vignettes describing groupings of people (e.g. married couple with children, two women and a child). Eighty per cent or more endorsed married and cohabiting families, lone‐parent households, and extended family members as families. Few differences were found according to their own family structure. Asian (Chinese) adolescents were less likely overall to endorse groupings as families. Love and affection were given as primary criteria for being a family. Overall, young people endorsed a diversity of family forms. Copyright © 2002 John Wiley & Sons, Ltd. 相似文献

In the 1950s Brunk and Van Eeden each obtained maximum-likelihood estimators of a finite product of probability density functions under partial or complete ordering of their parameters. Their results play an important role in the general theory of inference under order restrictions and lead to an isotonic estimator of the intensity of a nonhomogeneous Poisson process. Here an elementary derivation of the maximum likelihood estimator (m.l.e.) for the intensity of a nonhomogeneous Poisson process is given when several (possibly censored) realizations are available. Boswell obtained the m.l.e. based on a single realization as well as a conditional m.l.e. under the same conditions. An example is given to show that in the multirealization setup a conditional m.l.e. may not exist; the proofs are, we believe, new and elementary. An illustrative application is given. 相似文献

Recent years have witnessed an increasing popularity of corporate fitness programmes. Regular physical activity and, in particular, high aerobic fitness are associated with a lower risk of coronary heart disease. Apart from its beneficial effects on resting levels of blood pressure and cholesterol, fitness is believed to reduce the impact of psychological stress. This hypothesis has been put to the test in 33 studies examining the physiological stress response of groups selected to differ in their fitness level. Although some evidence was found for a reduced response to stress in high fit subjects, the effects were not very strong. During 54 confrontations with a stressful task, significantly lower heart rate reactions in high fit subjects were seen in only nine tasks (17%). With nine out of 36 stressors (28%), fit subjects showed a lower diastolic blood pressure response. However, in combination with a frequently found reduction in basal levels, the high fit showed a consistently favourable cardiovascular profile under stress. This adaptation may reflect the benefits of regular exercise over a more sedentary lifestyle, but a combined influence of genetic make-up on cardiovascular reactivity and fitness cannot be ruled out. 相似文献

Two things make Carl Cuneo's recent (1978) paper on 'rates of exploitation' in Canada remarkable. The first is the magnitudes involved. Cuneo's preferred measure of surplus value (RSV7 ), for instance, shows a more than seven-fold increase from 1917 to 1971, indicating a quite spectacular shift in favour of capital in relative income shares in Canadian manufacturing industry. The second thing that makes Cuneo's paper remarkable is the extent to which his findings are inconsistent with findings on income shares reported by 'bourgeois' economists. In a survey of the literature Pen (1971: 164 ff.), for example, reports that in the advanced capitalist economies, the share of income accruing to labour in the economy as a whole has increased substantially and that even if one confines one's attention to the private sector the share of manual workers has not decreased but remained more or less constant in spite of the relative decline in their numbers.1 Now, it is true that the studies reviewed by Pen approach the problem of income shares with the categories of 'bourgeois' economics while Cuneo approaches the problem with what he regards as Marxist categories, and it is conceivable that this might have accounted for the radical difference in the findings. But still, differences of such magnitude in the trends reported in the shares of capital and labour both give pause and urge a close scrutiny. 相似文献

This study examines the youth society which was created in the lycées and collèges of France in the nineteenth and early twentieth centuries. Using literary and social-historical records the personal and social experiences of youth in this milieu are delineated. A literary ethnography is constructed that presents a composite portrait of these actors'lives and society. In addition to certain beliefs, practices, and rules, authoritarian/coercive relations and hierarchical social structures are found to characterize this youth society. Attention is directed to the importance of explaining the emergence of this historical instance of a youth society within an elite school system in a way which identifies important structural processes operating in this setting and the larger societal context. 相似文献

Since the early 1990s in the Netherlands a process of restructuring social security has been going on. A central element is the introduction of regional Centres of Work and Income, stimulating people living on benefits to return to paid work and making services more client–oriented. In these centres, social security organizations and employment services are supposed to cooperate. In practice this cooperation is hard to accomplish. The intended activation of clients is hardly realized. The problems encountered by this policy are characteristic of a top–down reform strategy in a corporatist welfare state like the Netherlands. 相似文献

Many of the world's leaders appear to possess narcissistic characteristics (e.g., Deluga, 1997). This begs a question as to whether and why narcissistic individuals are chosen as leaders and how they perform. Prior research has suggested that leadership emergence and performance of narcissistic personalities may depend on contextual factors. Of particular interests are those contextual factors that pertain to the interdependence of work relationships, because narcissists typically tend to “shine” in social settings where they can influence others. Therefore, the present study investigated the leadership emergence and performance of narcissistic individuals in low versus high reward interdependent teams that participated in an interactive team simulation task. We found that narcissists emerged as leaders irrespective of the team's level of reward interdependence and their individual performance. Yet, high narcissists performed better in the high reward interdependent condition than in the low reward interdependent condition. 相似文献
