CHALLENGES FACING FEMALE DOCTORAL STUDENTS AND RECENT GRADUATES   总被引:2,自引:0,他引:2  
Although increasing the numbers of women and minority faculty in academia is a widely held goal, their numbers remain small. The presence of women and minorities decreases disproportionately at each ascending rung of the academic ladder. This investigation identified factors potentially contributing to attrition in White and non-White women at a critical stage in their careers: as doctoral candidates and recent graduates. Two-hundred and twenty-four women in the life sciences, social sciences, and the humanities described their most pressing professional and personal concerns and offered suggestions for changes in their fields and in academia more generally. Independent raters coded responses by thematic content. Differences in responses by field, educational status, and minority status were examined. The most frequently cited concerns involved practical issues such as finding employment, financial stability, and developing professional expertise, revealing wide-spread concerns about a competitive academic climate. Suggestions included modifications in professional conduct, the employment and pay structure, and training.  相似文献

The goal of this pilot study was to test the usefulness of a six session psychoeducational support group for women at high genetic risk for breast cancer who were considering prophylactic mastectomy. The themes of the group sessions included overestimation of and anxiety about risk; desire for hard data; the emotional impact of watching a mother die of breast cancer; concerns about spouse reactions; self- and body image; the decision-making process; and confusion over whom to trust in decision making. Both the participants and the multidisciplinary leaders concluded that as a supplement to individual counseling, a support group is a beneficial and cost-effective treatment modality. Recommendations for the optimal format for such a group are described.  相似文献

The purpose of this paper is to describe how to establish and maintain a low-cost zebrafish facility that can be used for both teaching and research purposes. The cost of the facility ranges from about 250 to250 to 1,000, depending on the size of the facility and the experiments that will be conducted. The facility plan presented here also has the advantage that it can be disassembled so that it need not function year-round. A detailed list of supplies and materials is provided, along with detailed instructions on how to set up and maintain the adult and breeding portions of the facility. Finally, there is discussion of some of the general uses of a zebrafish facility, including a variety of procedures that are currently being used in behavioral research with this species.  相似文献

In his recent bookExplaining Behavior, Fred Dretske has outlined a naturalized theory of intentionality. Several philosophers, including Dretske himself, view his theory as lending credence to the claim that mental state content should be construed widely. In this paper I argue that careful analysis of his theory reveals that this view is mistaken. In Dretske's theory, the notion of the function of a state plays a central role in the determination of content. It will be my contention that this notion of function cannot be used in Dretske's theory to distinguish between the wide construal of the content of an intentional state and the narrow or individualistic construal. This inability of his notion of function to discriminate between wide content and individualistic content undermines any claim that Dretske's theory endorses wide content. Instead, we are lead to the conclusion that Dretske's theory entails pervasive content indeterminacy.  相似文献

Three groups of women (ns = 10) undergoing hysterectomy were subjects in an evaluation of biofeedback and relaxation techniques applied to recovery from psychological trauma of hysterectomy. Dependent measures included requests of pain medications, anxiety levels, finger-tip temperature, subjective units of discomfort, and number of days post-operative care. Although the results were mixed on most variables, the number of days post-operative care was significantly less in the relaxation/biofeedback group.  相似文献

The acquisition of a 14-term partial ordering was compared with the acquisition of a 14-term linear ordering. Learning the partial ordering was found to be more difficult because of two factors: (1) Subjects do not appear to have in their knowledge systems a prototype or rule for representing a long list of comparative relations as a partial ordering structure, and (2) the partial ordering must be presented so that some of the adjacently presented premises do not contain a common element. When these two factors were controlled, the partial ordering was as easy to learn as the linear ordering. It was also found that subjects learning the partial ordering showed no evidence of a serial position learning curve, whereas subjects learning the linear ordering showed some tendency to produce a serial position learning curve.  相似文献

Examined the short-term impact of providing advocacy services to women leaving battered women's shelters. The study employed a true longitudinal experimental design. Women in the advocacy condition received intensive one-on-one services with trained paraprofessional advocates. Advocates assisted women in accessing needed community resources. Women in the control condition received no additional postshelter services. Findings corroborated earlier research suggesting that battered women lack many resources necessary for independent living and that working with advocates produced greater effectiveness in accessing needed resources. Ongoing research will examine the long-term impact on life satisfaction, future victimization, and living arrangements.  相似文献

Bronfenbrenner's (1977) ecological systems theory is a holistic framework placing an individual in a system's context to address their concerns. This article offers a case study demonstrating use of the theory with older adults and the in‐home setting. Implications for the counseling field and future research needs are discussed.  相似文献
