This study investigated the relationship among age, gender, and race relative to participation in self‐awareness, action‐oriented, and training activities after a job loss. The 156 respondents in this study were part of a larger, longitudinal study that collected data using questionnaires from outplacement program participants at 6 months and at 1 year following a company closing. Main effects were found for gender and for Age × Employment status. Implications of the study for outplacement programs, along with study limitations and future research directions, are discussed. 相似文献

Relations among and between religion, spirituality, and the ability to cope with stress were examined using a sample of 115 graduate students in counseling. Religion and spirituality positively correlated with coping with stress. Counseling students who expressed spirituality through religious beliefs had greater spiritual health and immunity to stressful situations than counseling students who identified themselves as spiritual but not religious. Counseling students with a religious/spiritual affiliation indicated more discomfort counseling clients hostile to religion compared with counseling students with a spiritual‐only affiliation. The results have implications for preparing counseling students to work with clients with religious/spiritual issues. 相似文献

DeFries and Fulker (1985) employed a multiple regression analysis of twin data in which a cotwin's score is predicted from the proband's score, the coefficient of relationship (R = 1.0 for monozygotic twins and 0.5 for dizygotic twins), and their interaction to yield direct estimates of heritability (h2) and the proportion of variance due to common or shared environmental influences (c2). The purpose of the report is to extend this model to allow for the analysis of data from more than two familial relationships simultaneously. Data from identical twins, fraternal twins, and siblings pairs, in which one member of each pair was selected based on low reading performance, were analyzed. To analyze the data simultaneously, additional coefficients were added to the regression equation in order to differentiate shared environmental influences of twins and siblings. When the model was applied to the combined cognitive data, significant estimates for heritability were obtained in three of the six tests analyzed. The results also indicated a lack of justification for the separate twin and sibling environmental parameters, and a discussion of more parsimonious models is included. 相似文献

The present study compared two hypotheses about children's solutions to Piaget and Inhelder's (1975) two-set alternative choice probability problems. The first was that children follow rules that specify a temporally ordered sequence of tests and decisions (Siegler, 1981). One prediction of rules is that children who know strategies that combine variables within sets (e.g., ratio or subtraction strategies) will only use them on problems that require such strategies (conflict problems), whereas lower level (nonconflict) problems will be solved by directly comparing the values of variables between sets. The second hypothesis was that once children develop knowledge of within-set solutions to probability problems, they apply them to both conflict and nonconflict problems. The results supported the latter hypothesis. The majority of children who solved conflict problems using within-set strategies explained at least one nonconflict problem by referring to within-set combinations. Results were discussed in terms of their implications for cognitive development and for instruction. 相似文献
