科学与艺术是塑造人类文明和福祉的两大精神力量。人类的实力、尊严以及关于自身的理想形式之确立 ,都以这两大精神力量为基础。科学与艺术的关系并非是外在的、偶然的联系 ,而是内在的、血肉相关的。文章以科学史的名著为第一手资料 ,剖析了关于近代科学诞生的一个重要史实 ,说明了科学与艺术之间与生俱来的固有关系。 相似文献

This article addresses cultural adaptation of Western‐Palestinian intermarried couples. Using in‐depth interviews, information was gathered from 16 participants, 7 Western women and 9 Palestinian men, living in Palestinian cities in the West Bank. Adaptation strategies are typified by the extent to which each spouse embraces the partner's culture. The data suggest that intermarriage engenders a multidirectional adaptation process. Patriarchy and East‐West power relations affect mainly the women, having to face marginalization on the basis of their gender and their foreignness. The men undergo a double process of cultural adaptation: to the Western culture and to their native culture after their return. Both the husbands’ extended family and the Israeli‐Palestinian conflict were found to affect both partners’ adaptation. 相似文献

In this article, we contend that the field of psychology has largely failed to foreground the role of gender in its study of immigration. Here, we review studies that address gender and migration focusing on the experience of children and adolescents. We provide developmental perspectives on family relations, well‐being, identity formation, and educational outcomes, paying particular attention to the role of gender in these domains. We conclude with recommendations for future research, which include the need to consider whether, and if so, how, when, and why it makes a difference to be an immigrant, to be from a particular country, or to be female rather than male. We argue that it is important to consider socioeconomic characteristics; to consider resilience as well as pathology; and to work in interdisciplinary ways to deepen our understanding of the gendered migratory experience of immigrant origin youth. 相似文献

Mothers' time‐use patterns were compared in families in which infants spent more than 30 hours per week in child care (In‐Care group; n= 143) versus 0 hours per week (At‐Home group; n= 183) from birth to 6 months of age. In‐Care group mothers spent about 12 fewer hours per week interacting with their infants, for about 32% less time; fathers of these infants were more involved in caregiving. The groups did not differ in the quality of mother‐infant interaction. In the In‐Care group, quantity of interaction was related to greater separation anxiety and concerns about effects of maternal employment. Time‐use data were not related to child outcomes at 15 months of age. Results suggest that the effect of extensive time spent apart on the quantity and quality of mother‐infant interaction may be smaller than anticipated. 相似文献

Toddlers' knowledge of the stereotyping of traditionally feminine and masculine household activities was examined using the preferential looking paradigm. Seventy‐seven 24‐month‐old infants observed a series of 9 pairs of photographs, each portraying a male and female adult engaged in the same stereotyped or gender‐neutral activity (e.g., ironing, hammering, or reading). Longer looking times were predicted on stimuli inconsistent with gender stereotypes (e.g., looking longer at the man putting on lipstick than at the woman). The results suggested that toddlers have acquired some knowledge of the gender stereotyping of feminine activities by their 2nd birthday. 相似文献
