This study examines associations between the quality of the interparental relationship and how well 68 family triads (mother, father, preadolescent son) solved salient problems which arose at home. Four aspects of the interparental relationship (marital satisfaction, parental agreement, conflict during family problem solving, and parental coalitions) were included in a regression analysis which controlled for family structure and child externalizing. A longitudinal design assessed families when mean child age was 9.7 years and 2 years later. Parental agreement consistently facilitated family problem solving. However, strong parental coalitions inhibited family problem solving, which may be attributed to frustrated autonomy needs of preadolescent males in response to the parental coalition. Stepfamilies had less effective problem solving at Time 1. The results confirm the benefits of parental agreement to child outcomes via enhanced family problem solving but show a reverse effect when agreement occurs in the context of coalitions against a preadolescent son. 相似文献

In attempting to develop a predictive model of student attachment to the university, this research concentrates on four variable sets: perceptions of university goals, perceptions of university academic climate, perceptions of university academic environment, and feelings of academic alienation. Using a sample of 460 university students, multiple discriminant analytic results indicate that of these four variable sets, perceptions of the academic climate and feelings of academic alienation exert more influence on students' attachment to the university than do perceptions of university goals and perceptions of the academic environment. These findings are discussed within the context of a model of the university student operating very much as a democratic citizen in the university political system. 相似文献

A number of psychometricians have suggested that parallel analysis (PA) tends to yield more accurate results in determining the number of factors in comparison with other statistical methods. Nevertheless, all too often PA can suggest an incorrect number of factors, particularly in statistically unfavorable conditions (e.g., small sample sizes and low factor loadings). Because of this, researchers have recommended using multiple methods to make judgments about the number of factors to extract. Implicit in this recommendation is that, when the number of factors is chosen based on PA, uncertainty nevertheless exists. We propose a Bayesian parallel analysis (B-PA) method to incorporate the uncertainty with decisions about the number of factors. B-PA yields a probability distribution for the various possible numbers of factors. We implement and compare B-PA with a frequentist approach, revised parallel analysis (R-PA), in the contexts of real and simulated data. Results show that B-PA provides relevant information regarding the uncertainty in determining the number of factors, particularly under conditions with small sample sizes, low factor loadings, and less distinguishable factors. Even if the indicated number of factors with the highest probability is incorrect, B-PA can show a sizable probability of retaining the correct number of factors. Interestingly, when the mode of the distribution of the probabilities associated with different numbers of factors was treated as the number of factors to retain, B-PA was somewhat more accurate than R-PA in a majority of the conditions. 相似文献

This paper reviews experience with teaching procedures introduced into an engineering design course to promote professionalism in undergraduates. One procedure used is a prize award for performance in project work and the other procedure is a Socratic style of teaching in the classroom. Both procedures intend to shift responsibility for learning away from the teacher towards the student. Student performance is measured by project results, examination results and by design studies. It is found that the use of design studies, a type of student centered examination procedure, has the most profound effect on performance in this complex subject. 相似文献

An analysis of medical schools was conducted by means of a factor analysis of multiple demographic measures. Three factors emerged which described the principal dimensions that characterize four-year medical school environments. Upon comparing these factors with a previous study, it was apparent that the environmental characterization for medical schools have remained generally constant over the last several years. An additional factor, Graduate Emphasis, was, however, identified. A visual representation is presented to demonstrate the similarity of the medical schools on these three factors. 相似文献
