Abstract. A strategy for deeding systematically with such complex relationships as those between science and theology is presented after a brief overview of the historical record and illustrated in terms of the concept of divinity. The application of that strategy to the title relationships yields a multilogical/multilevel solution which presents certain analogies to or isomorphisms with the doctrine of the Trinity. These concern mainly the multilogical/multilevel character of both conceptualizations and the relational and contextual reasoning required to conceive them. Furthermore, certain characteristics of the doctrine facilitate the dialogue between theologians and scientists on account of their similarity with such scientific concepts as diversity in unity, multiplicity of relationships, nonseparability, and nonclassical logic. 相似文献

Abstract. In 1994 the John Templeton Foundation Humility Theology Information Center launched a major initiative, the Science-Religion Course Program, to encourage the teaching of high-quality academic courses focusing on the relationship between science and religion. In the first phase of the program, six courses were selected—four from the United States, one from Canada, and one from New Zealand—to serve as models for other academics wishing to initiate their own classes on the science-religion interface. In particular these six model courses will serve as examples for the second phase of the Templeton Foundation program, which will provide financial support for up to 100 courses at universities, colleges, and seminaries around the world. This paper is a report on the pedagogical strategies and methodologies employed in each of the six selected model courses. 相似文献

Effects of a variable-ratio conditioning history on sensitivity to fixed-interval contingencies in rats. 总被引:7,自引:7,他引:0

We investigated the possibility that human-like fixed-interval performances would appear in rats given a variable-ratio history (Wanchisen, Tatham, & Mooney, 1989). Nine rats were trained under single or compound variable-ratio schedules and then under a fixed-interval 30-s schedule. The histories produced high fixed-interval rates that declined slowly over 90 sessions; differences as a function of the particular history were absent. Nine control animals given only fixed-interval training responded at lower levels initially, but rates increased with training. Despite differences in absolute rates, rates within the intervals and postreinforcement pauses indicated equivalent development of the accelerated response patterns suggestive of sensitivity to fixed-interval contingencies. The finding that the histories elevated rates without retarding development of differentiated patterns suggests that the effective response unit was a burst of several lever presses and that the fixed-interval contingencies acted on these units in the same way as for single responses. Regardless of history, the rats did not manifest the persistent, undifferentiated responding reported for humans under comparable schedules. We concluded that the shortcomings of animal models of human fixed-interval performances cannot be easily remedied by including a variable-ratio conditioning history within the model. 相似文献

This study examined stability and change in patterns of mother-infant interaction between 5 and 10 months and their relation to attachment security at 18 months. Cluster analysis was used to identify patterns of dyadic interaction. There was significant, but not substantial, stability in cluster membership from 5 to 10 months. For females, being in the most optimal cluster at 5 months related to subsequent attachment security, regardless of the 10-month pattern of interaction. For males, who were significantly more likely to be insecure than females, insecure attachment was predicted by negative change from 5 to 10 months (moving from a more optimal to a less optimal cluster). 相似文献

Agnes Verbiest 《Argumentation》1995,9(5):821-836
An incidental extension of the central domain of argumentation theory with non-classical ways of constructing arguments seems to automatically raise a question that is otherwise rarely posed, namely whether or not it is useful to consider the sex of the arguer. This question is usually posed with regard to argumentation by women in particular. Do women rely more, or differently than men do on non-canonical modes of reasoning stemming from the realm of the emotional, physical and intuitive, instead of the logical? One may simply refer this question to folk-linguistics. One may also take the question seriously, given the findings on women's linguistic behaviour, and for various other reasons that will be explained below.Section 1 sums up the most frequently quoted differences in language use between women and men. This is followed by a non-exhaustive, interdisciplinary review of studies on male/female differences in verbal and written argumentation.Section 2 discusses the role of language and texts in generating and maintaining ideas on gender. These gender messages not only influence the actual argumentation behaviour of women and men, but also the way such behaviour is valued.Section 3 subsequently shows that our ideas on rationality are gendered, and therefore also our ideas on the proper central domain of argumentation theory.Section 4 briefly reflects on why this kind of wrong question about the reasoning of women should sometimes be addressed seriously anyway. 相似文献

Over the past three decades, Arab society in Israel has been undergoing processes of transition. These processes are manifested by changes in the economy, education, the status of women, family structure, and by socio-cultural changes and transformations in patterns of coping with social problems. There is a serious lack of empirical research on the implications of this process for the value systems of Arab society and families in Israel and a dearth of relevant intervention-oriented literature. This article outlines the basic cultural values in the Arab society in Israel in an attempt to illuminate the relevance of these values for family structure and for direct interventions with Arab families in Israel. 相似文献

大学生场依存性─-独立性认知方式分析 总被引:14,自引:0,他引:14
对二十一个学科专业1526名大学生的场依存性─-独立性认知方式进行调查所获得的新近常模资料表明:大学生场依存性─-独立性个体差异的群体分布是正态性的,其总体平均水平以《认知方式图形测验》成绩作指标为13.7(s为4.6)。在此基础上,对文献所报道的影响场依存性─-独立性发展水平的两个因素作了进一步的研究分析,发现,大学生场依存性─-独立性的性别差异非常接近显著水平;专业分化是不依赖于性别因素而导致大学生场依存性─-独立性水平显著不同的主要因素. 相似文献

The total workload of male and female white collar workers as related to age, occupational level, and number of children 总被引:13,自引:0,他引:13

A questionnaire assessing various aspects of paid as well as unpaid forms of productive activity was mailed to stratified samples of male and female white collar workers, approximately matched for educational and occupational level. Data from 501 men and 679 women employed full time revealed traditional gender differences in terms of main responsibility for household duties, child care etc. In keeping with this, women reported higher levels of work overload, stress and conflict than men, which increased significantly with the number of children at home. The various stress indices reached a peak between the ages of 35 and 39. Men reported more autonomy in their paid work whereas women reported more control at home. Men and women at the upper managerial levels reported more control over their total work situation and less conflict between demands. 相似文献

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
