In June 1986, the new Military Retirement Reform Act was signed into law with the intention of saving $2.9 billion in the 1986 accrual funding of the military retirement budget. This article provides an analysis of the potential effects of the new policy on personnel retention. It concludes that the losses of personnel due to the new retirement system are likely to be much larger than expected, the proportion of higher-quality personnel is likely to be reduced, and policies that can moderate these effects would dilute the intended future cost savings. 相似文献

Emotional and behavioral correlates of Type A behavior in children and adolescents were examined in 184 fifth-, seventh-, and ninth-grade students, classified as high or low Type A, using self-report, teacher ratings (fifth grade only), and structured interview procedures. Measures included the Hunter-Wolf A-B Rating Scale, Behavioral Symptoms of Stress Inventory, Dimensions of Temperament Survey, Desire for Control Scale, Eysenck Personality Inventory, and the Multiple Affect Adjective Checklist. High Type A children reported significantly more stressed-related behaviors, higher levels of depression, anger, anxiety, and cognitive disorganization, and greater reactivity than Low Type A. No differences were found on measures of temperament (activity level, attention span, adaptibility, and rhythmicity), desire for control, or introversion-extroversion. Females, in general, reported significantly more behavioral stress symptoms. However, no other gender differences were found. Possible reasons for reported differences between Type A children and adults are discussed, along with gender differences in behavioral symptoms. Need for multiple measures of Type A across situation is considered along with need for controlled longitudinal studies of Type A components and the influence of contexts.Received Ph.D. from Stanford.

Eighty college males were given an expanded identity status interview which included two new interpersonal-sexual areas, “attitudes towards sexual expression” and “sex-role beliefs.” The relative contribution of the new content areas as well as of the standard three areas (occupation, religion, and politics) to overall identity status was assessed by noting the extent of correspondence. Identity status in each content area was also compared with performance on the dependent variable of cognitive complexity. Ideology contributed more than occupation both to overall status rating, as well as to discrimination on the dependent variable. Results on the two new areas supported the view that interpersonal-sexual concerns are important for men's identity development as well as for women's. The finding that all interview areas corresponded well with overall identity status and discriminated significantly on the dependent measure leads to the suggestion that the process variables of crisis and commitment may so overshadow a particular content area that any content of personal relevance for the late adolescent might be used in investigating ego identity development. 相似文献

A path-analytic study was undertaken to investigate the proposed relationship between physical attractiveness, need for intimacy, self-disclosure, thought about one's dating partner, and reported romantic love. Extrapolations from theories by Murstein (1971) and I. Reiss (1960), and conclusions from other empirical work, provided the background for the assessment of the relationship between the four proposed predictive factors and the development of romantic affect. During the winter of 1977-78 656 college students responded to a survey assessing each of the four predictors and romantic love. Path structures were initially estimated for male and female subsamples. Since few significant sex differences were noted, coefficients were compared for groups of students involved in dating relationships of varying durations. All four predictors were significantly associated with the subjects' self-reported romantic affect toward their dating partner. In all analyses, thinking about one's partner was found to be the most potent predictor. The data suggest the earlier work by Murstein and Reiss offer both testable and productive theoretical foundations for the study of romantic involvement. However, in future work it would be beneficial to (a) search for more numerous and powerful antecedents to romantic love; (b) delineate the specific role of cognitive processes in influencing romantic attachment; (c) compare relationships on criteria other than months of involvement; and (d) seek to examine love from the perspectives of both individuals involved in the dyadic relationship.Received her Ph.D. from the Pennsylvania State UniversityReceived his Ph.D. from The Pennsylvania State University. 相似文献

To investigate the incidence and correlates of bulimic behavior, 1268 high school females were surveyed. A 47-item questionnaire was used to identify a group of students that would meet the DSM-III criteria for a probable diagnosis of bulimia. Students were then compared across the four content areas of demographics; body perception and weight information; dieting, exercise and menstrual behavior; and frequency of bingeing and purging behavior. Results indicated that 4.9% of the students met rigorous criteria for the diagnosis of bulimia. Between-group comparisons indicated that body dissatisfaction, drive for thinness, and chronicity of dieting differentiated the two groups.This work was supported by Biomedical Research Grant #RR5476, the Sears Allstate Foundation, and the George and Tina Barr Foundation.Main interest is eating disorders. 相似文献
