On the basis of an adult model of sibling attachment, I hypothesized that the well-being of older persons depends on their perception of the closeness of the sibling bond, on their perception of any disruption of that bond, and on the sex combination of the siblings being considered. In all, 83 persons, aged 61 to 91 years, were interviewed about their relationships with each of their living siblings. They rated their feelings of closeness, conflict or rivalry, and indifference to the sibling. A measure of depression was used as the indicator of well-being. Separate correlational analyses were carried out for the four sex combinations of siblings. Closeness of the bond to a sister (by both men and women) was related to less depression. Also, women's perceptions of conflict and indifference in their relationships with sisters were related to increased depression. Findings are interpreted in terms of attachment theory and sex role expectations.  相似文献

Differences in psychological androgyny and attitudes toward women were examined in male Caucasian intercollegiate contact and noncontact sport athletes and male Caucasian college nonathletes. Contact athletes in the sports of football and wrestling, noncontact athletes in the sports of baseball and track and field, and nonathletes completed the Attitudes Toward Women Scale (ATWS) and the Bem Sex Role Inventory (BSRI) to assess egalitarian attitudes toward women and sex role orientation. Results of analyses of variance (ANOVAs) on the ATWS indicate that athletes as a group possessed more conservative, traditional attitudes toward women than did nonathletes, but that no differences existed between contact sport athletes and noncontact sport athletes. Results of ANOVAs and chi-square analyses on the BSRI indicated no differences between groups regarding sex role orientation based upon self-perceptions of masculinity and femininity.  相似文献

Some properties are discussed of regular polygons that may result from angular homeostatic processes in stable orbit. To characterize these homeostatic polygons we need to discuss the winding number, the sidedness (integer, fractional and irrational), multiplicity, envelopes, and density. A regular (i.e., equilateral, equiangular) polygon may be closed in one revolution about its unique center, in multiple revolutions, or not at all. A homeostatic polygon can be generated only if all vertices are included in a single polygon, which occurs if and only if the number of vertices and the number of revolutions required to complete the polygon are relatively prime. For the homeostatic polygon to have a finite number of sides (without repeating itself) the angle subtended by any two successive vertices at the center must be a rational multiple of 2. Biological implications of these properties are illustrated.  相似文献

The author reviews aspects of psychoanalytic theory which have helped him in his career as an American diplomat and political analyst. He cites the works of Erikson (1950, 1968, 1969), Volkan (1979, 1987), and Mack (1979, 1983) as especially helpful, and praises the late Jeanne Knutson, founder of the International Society of Political Psychology, for her work on the psychology of victimhood. The role and function of completed and incomplete mourning are discussed as fundamental aspects of unresolved ethnic and sectarian conflict, and the importance of asking and granting forgiveness in the resolution of violent political conflict is explored. The paper ends with a specific application of the meaning of forgiveness in the relationship between Christians and Jews.  相似文献

The purpose of this study was to examine differences in older adolescent and adult females' perceptions of age-appropriate behavior in adults. Subjects were three generations of maternally related females (95 older adolescents, 78 mothers, 83 grandmothers) who were administered a questionnaire designed to assess age-appropriate behaviors in three broad categories: recreation, occupation/career, and family. Major findings were that older adolescents were most tolerant of behaviors performed by individuals at varying ages while older women most closely ascribed to age constraints, and that the greatest agreement on appropriateness of age constraints concerned family relationships while least agreement concerned recreational activities. Results support the view that adolescents' values on family issues are consistent with those of their parents, and suggest that adherence to age norms increases throughout the life span or are the result of generational differences in socialization.  相似文献
