The author describes some of the effects of decades of life under a dictatorship for East Germans and the effects on family life and family therapy of changes following the recent reunification of Germany. A case example illustrates some intergenerational family problems associated with the changes. Contrasts are drawn between East and West Germany and family therapy's present stage of development is depicted in both parts of the reunified country. Germany has approximately 10,000 trained family therapists, a minority of whom work in private practice. The largest amount of family and couples therapy is performed in agencies.Portions of this material were first presented in a poster session at the American Association for Marriage and Family Therapy annual conference in Miami Beach, 1992.  相似文献

This international, five-country long term marriages study of couples who have been married, or unmarried and cohabiting, for 20 years or longer is designed to study, among other things, marital satisfaction. This first report of the Swedish part of the study reports on a Swedish version of the self-rating Dyadic Adjustment Scale (DAS) used to investigate self-rated marital satisfaction. The couples describe high marital satisfaction and a high sense of coherence (SOC) compared to other groups. Contrary to other studies, no differences were found between men and women regarding SOC. The differences between them, that describe high relative to low marital satisfaction, pertain to matters of recreation, sex, life philosophy, time spent together, and frequency of quarrels. The men reported greater marital satisfaction than the women.  相似文献

飞行错觉水平评定方法的初步研究   总被引:7,自引:0,他引:7  
本文从飞行错觉发生的类型和频率出发,尝试对飞行员在实际飞行中所产生的错觉水平或空间定向能力做出基本的评定。本研究采用区间模糊统计的方法,对飞行错觉的类型(倾斜错觉、俯仰错觉、方位错觉、反旋转错觉和倒飞错觉)和频率(从无、偶尔、时有、经常、总是)做了经验的赋值工作,分别计算出了这些模糊概念(除从无外)的心理量表值和模糊度。同时我们认为,飞行错觉水平是频率与类型的函数,其数学表达式为:,并将这一表达式作为评定飞行员飞行错觉水平的基本模型。  相似文献

Aristotle's illustrations of the fallacy of Figure of Speech (or Form of Expression) are none too convincing. They are tied to Aristotle's theory of categories and to peculiarities of Greek grammar that fail to hold appeal for a contemporary readership. Yet, upon closer inspection, Figure of Speech shows many points of contact with views and problems that inhabit 20th-century analytical philosophy. In the paper, some Aristotelian examples will be analyzed to gain a better understanding of this fallacy. The case of the Third Man argument and some modern cases lend plausibility to the claim that Figure of Speech is of more interest as a type of fallacy than has generally been assumed. Finally, a case is made for the view that Figure of Speech, though listed among the fallacies dependent upon language, is not properly classified as a fallacy of ambiguity. More likely, it should be looked upon as a type of non sequitur. This has important consequences for the profile of dialogue associated with this fallacy.  相似文献

Individual and institutional conflict of interests in biomedical research have becomes matters of increasing concern in recent years. In the United States, the growth in relationships — sponsored research agreements, consultancies, memberships on boards, licensing agreements, and equity ownership — between for-profit corporations and research universities and their scientists has made the problem of conflicts, particularly financial conflicts, more acute. Conflicts can interfere with or compromise important principles and obligations of researchers and their institutions, e.g., adherence to accepted research norms, duty of care to patients, and open exchange of information. Disclosure is a key component of a successful conflict policy. Commitments which conflict with a faculty member's primary obligations to teaching, research, administrative responsibilities, or patient care also need attention. Institutional conflict of interests present different problems, some of which are discussed in an analysis of an actual problem posed by two proposed clinical trials. This paper is adapted from a lecture presented to a Symposium on Scientific Integrity, Warsaw, Poland, 23 November 1995. Daniel Steiner was Vice-President and General Counsel of Harvard University (1972–92) and in that capacity became familiar with conflict of interest issues. He is currently Counsel to the Boston law firm. Ropes and Gray, and is Adjunct Lecturer in Public Policy at the John F. Kennedy School of Government. Harvard University.  相似文献

The question addressed in this study is whether experts are better calibrated than lay people. We investigated how well people are calibrated when they assess the probabilities of card combinations in the game of blackjack. Three groups of subjects were used: professional dealers, statistical experts, and control subjects. The results showed that experience and statistical expertise do not make people better calibrated in this task. It is argued that the concept of calibration is not wholly appropriate to describe the obtained deviations from the normatively correct responses. This is illustrated by a discriminant analysis performed on the signed deviation scores, which resulted in an almost perfect separation of the three groups, although they were overlapping with respect to calibration.  相似文献

Lane has argued that kantowitz and Knight incorrectly predicted an interaction between primary and secondary task difficulty for the variable-allocation model of attention. It is shown that such an interaction is indeed obtained if task-performance difficulty is defined in terms of capacity and only reasonable transformations of data are permitted. This interaction holds for any set of monotonic resource operating characteristics.  相似文献
