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

The transfer of conditioned modulation across conditioned stimuli (CS) and unconditioned stimuli (US) was examined in 3 experiments that used Pavlovian appetitive training procedures with rats. In Experiment 1, after training in a positive patterning discrimination (X-->A+/X-/A-), X increased conditioned responding elicited by another trained-then-extinguished CS as long as that CS had been trained with the same US as was used in discrimination training. In Experiment 2, after training with a feature-negative discrimination (X-->A-/A+), X inhibited conditioned responding elicited by another trained-then-extinguished CS as long as that CS had been trained with the same US. Experiments 1 and 2 used a between-groups design, whereas Experiment 3 used a more powerful within-groups design. In Experiment 3, rats were trained in a feature-positive discrimination (X-->A+/A-). In transfer tests, X increased conditioned responding elicited by another CS trained then extinguished with the same US from training. This increase was greater than the X increased conditioned responding elicited by another CS trained then extinguished with a different US from training. The results supported the suggestion that features trained in serial discrimination tasks influence behavior indirectly by transiently raising or lowering the threshold for activation of the US representations by its target stimuli and by any other stimuli that may be associated with that US. Other interpretations of the findings were also considered. 相似文献

Source memory has been found to be more affected by aging than item memory, possibly because of declining frontal function among older adults. In 4 experiments, the authors explored the role of the frontal lobes (FLs) in source memory, the extent to which they may be involved in the encoding and/or retrieval of source or context, and the conditions under which the source memory deficit in older people may be reduced or eliminated. Results indicated that only a subset of older adults show deficits in source memory, namely those with below average frontal function, and these deficits can be eliminated by requiring people at study to consider the relation between an item and its context. These results provide convincing evidence of the importance of frontal function during the encoding of source and suggest that older adults with reduced FL function fail to initiate the processes required to integrate contextual information with focal content during study. 相似文献

Stress and Gender in Unemployed Female and Male Managers 总被引:1,自引:0,他引:1
The purpose of this pioneering study was to investigate the overall impact of unemployment on female managers compared to their male counterparts, an area which to date has received no specific attention. A questionnaire was designed based on a review of the relevant literature and content analysis of in‐depth interviews with 40 unemployed managers. This was distributed to the 80 government run Executive Job Clubs located throughout England, and was used to gain quantitative data exploring respondents' experiences of unemployment in terms of sources of stress, stress moderators, and stress outcomes. Completed questionnaires were received from 115 female and 169 male unemployed managers registered at 46 Executive Job Clubs (return rate 47%). Multiple regression techniques were used to develop individual and comparative models of unemployment for unemployed female and male managers. The findings indicated that unemployed female managers encountered substantially greater sources of stress than their male counterparts in all aspects of unemployment. Increased stressors and less effective stress moderators resulted in female managers experiencing significantly poorer mental well‐being and greater negative physical effects during unemployment than their male counterparts. Recommendations are made to key organisations. 相似文献

This study tested the prediction that individual differences in self-actualization would be associated with six academic orientations which influence college students' adjustment to their studies. Volunteer undergraduates, solicited from courses in the sciences and liberal arts and invited to complete internet measures of the academic orientations and self-actualization were 137 men and 311 women (M age=21.1, SD=4.8). Statistically significant bivariate correlations obtained between scores on self-actualization with all six orientations: creative expression, reading for pleasure, academic efficacy, and, inversely, structure dependence, academic apathy, and mistrust of instructors. Regression analysis showed that four orientations were independently related to self-actualization scores. The role of these four orientations in actualizing students' adjustment was discussed, and implications were drawn about the interpretation of scores on the four orientations. 相似文献

Biallelic germline mutations in mismatch repair genes predispose to constitutional mismatch repair deficiency syndrome (CMMR-D). The condition is characterized by a broad spectrum of early-onset tumors, including hematological, brain and bowel and is frequently associated with features of Neurofibromatosis type 1. Few definitive screening recommendations have been suggested and no published reports have described predictive testing. We report on the first case of predictive testing for CMMR-D following the identification of two non-consanguineous parents, with the same heterozygous mutation in MLH1: c.1528C > T. The genetic counseling offered to the family, for their two at-risk daughters, is discussed with a focus on the ethical considerations of testing children for known cancer-causing variants. The challenges that are encountered when reporting on heterozygosity in a child younger than 18 years (disclosure of carrier status and risk for Lynch syndrome), when discovered during testing for homozygosity, are addressed. In addition, the identification of CMMR-D in a three year old, and the recommended clinical surveillance that was proposed for this individual is discussed. Despite predictive testing and presymptomatic screening, the sudden death of the child with CMMR-D syndrome occurred 6 months after her last surveillance MRI. This report further highlights the difficulty of developing guidelines, as a result of the rarity of cases and diversity of presentation. 相似文献

Learning about objects often requires making arbitrary associations among multisensory properties, such as the taste and appearance of a food or the face and voice of a person. However, the multisensory properties of individual objects usually are statistically constrained, such that some properties are more likely to co-occur than others, on the basis of their category. For example, male faces are more likely to co-occur with characteristically male voices than with female voices. Here, we report evidence that these natural multisensory statistics play a critical role in the learning of novel, arbitrary associative pairs. In Experiment 1, we found that learning of pairs consisting of human voices and gender-congruent faces was superior to learning of pairs consisting of human voices and gender-incongruent faces or of pairs consisting of human voices and pictures of inanimate objects (plants and rocks). In Experiment 2, we found that this “categorical congruency” advantage extended to nonhuman stimuli, as well—namely, to pairs of class-congruent animal pictures and vocalizations (e.g., dogs and barks) versus class-incongruent pairs (e.g., dogs and bird chirps). These findings suggest that associating multisensory properties that are statistically consistent with the various objects that we encounter in our daily lives is a privileged form of learning. 相似文献
