This study examined the relative influence of three parenting behaviors (support, behavioral control, and psychological control) and deviant peers on trajectories of externalizing and internalizing problems in early adolescence. A white, working-to-middle-class sample of adolescents and their mothers and fathers in two-earner families participated in a 32-year longitudinal study (N = 109 families). The study began when the adolescents were in sixth grade (M age = 11.5 years). Analyses showed that parents' firm behavioral control seemed to halt the upward trajectory in externalizing problems among adolescents with deviant peers. Initial levels of internalizing problems were higher among adolescents with parents who reported lower levels of behavioral control and among adolescents with deviant peers. This study suggests that parenting exerts an important influence in adolescents' lives and may do so even in the face of potentially negative peer influence. 相似文献

Our ability to understand the faculty work environment has been greatly enhanced by the availability of largescale national surveys of the professoriate since the 1950s. This technical note identifies ways to improve data comparability among the national faculty surveys. It begins by identifying the national surveys and some of their attributes. The study then estimates faculty sizes and calculates weights for faculty in selected disciplines and institution types. The weights are designed specifically for four surveys conducted in 1969, 1975, 1980, and 1988. 相似文献

This study assessed the relationship between the frequency of college students' informal nonclassroom contact with faculty for each of six purposes and their generalized perceptions of instructional quality. Two factorially derived components of instructional quality (based on a 14-item instrument) were used as the dependent variables in two regressions on the six types of contact. The frequency of contacts for discussing intellectual or course-related matters and for discussing a campus issue or problem made statistically significant and unique contributions in predicting students' perceptions of instructor concern and ability.An earler version of this paper was presented to the annual conference of the American Educational Research Association, Boston, April 1980. 相似文献

This is a report of a small study of non‐response to an evaluation questionnaire. Evidence is provided in support of the view that non‐response is independent of the questions. Some practical advice is provided for conference evaluators. 相似文献

Animals poisoned following exposure to saccharin subsequently avoided the schedule-induced consumption of saccharin. While this suppression was transient for subjects who had access only to the saccharin solution during the free-food presentations, recovery of schedule-induced saccharin consumption was significantly retarded for subjects who had concurrent access to saccharin and a running wheel. It has been suggested that the transient suppression of schedule-induced polydipsia by conditioned taste aversions results from the pellet-induced tendency to drink within the schedule-induced polydipsia procedure. That access to the running wheel reduces schedule-induced polydipsia in general and prolongs the suppression of schedule-induced polydipsia by taste aversions supports this view. 相似文献

With the increasing use of international survey data especially in cross-cultural and multinational studies, establishing measurement invariance (MI) across a large number of groups in a study is essential. Testing MI over many groups is methodologically challenging, however. We identified 5 methods for MI testing across many groups (multiple group confirmatory factor analysis, multilevel confirmatory factor analysis, multilevel factor mixture modeling, Bayesian approximate MI testing, and alignment optimization) and explicated the similarities and differences of these approaches in terms of their conceptual models and statistical procedures. A Monte Carlo study was conducted to investigate the efficacy of the 5 methods in detecting measurement noninvariance across many groups using various fit criteria. Generally, the 5 methods showed reasonable performance in identifying the level of invariance if an appropriate fit criterion was used (e.g., Bayesian information criteron with multilevel factor mixture modeling). Finally, general guidelines in selecting an appropriate method are provided. 相似文献

This article analyses educational research on gender inequality carried out in the Netherlands between 1982 and 1991. It can be regarded as a case study on the conceptualisation of the problem of gender inequality in education. In the Netherlands two types of research can be identified: policy‐orientated research, which was largely concerned with primary and secondary education, and action research which developed from within and focused on adult education. In the beginning most researchers in both types of research were aware of the problems related to the concept of ‘disadvantage’. Later on, policy‐orientated research on gender and education has increasingly approached education primarily as a means of preparing for a promising position on the labour market. The concept of disadvantage, which at first appeared to have been superceded, has been frequently applied in the analysis of gender in education. Action research, however, focused on the learning processes of women considering feminine qualities to be positive and valuable. We discuss the criticism from women's studies of the research carried out. Finally, the central concepts of the Dutch research are related to the classifications used in England. 相似文献

This study investigated the relationships between demographic characteristics, motives and attitudes to studying, self-reported
study behaviour and measures of outcome. Students taking courses by distance learning received a postal survey containing
a short form of the Motivated Strategies and Learning Questionnaire (MSLQ) and the Revised Approaches to Studying Inventory
(RASI). Path analysis was used to assess the causal relationships among 395 students’ age, gender and prior qualifications,
their scores on the MSLQ and the RASI and their marks. Evidence was obtained for the causal efficacy of most of the paths
among the main components. In particular, the causal link between variations in students’ motives and attitudes and variations
in their study behaviour is bidirectional. 相似文献
