The nexus between college choice and persistence 总被引:2,自引:3,他引:2

Initial student commitments have long been considered an influence on persistence, but the reasons why students choose to attend a college have seldom been considered as dimensions of initial commitments that could influence persistence processes and outcomes. This study used NPSAS-87 to examine the influence of finance-related reasons for choosing a college on persistence decisions. The findings include (1) finance-related choices have direct and indirect influences on whether students persist in college; and (2) market-based, monetary measures of financial aid, tuition costs, housing costs, and other living costs have a substantial direct effect on persistence. 相似文献

Evidence of substantial growth in unionization among university noninstructional staff over the past 20 years (Hurd and Woodhead, 1987) and the emergence of a quality movement in higher education linking employee attitudes toward the work environment with increased productivity point to the need for additional research into union and nonunion staff perceptions of the work environment. This paper describes a conceptually oriented, exploratory study of the university work environment as perceived and defined by union and nonunion noninstructional staff. 相似文献

To explore Daft's dual-core model of educational organization, this study compares the managerial behavior of academic department chairpersons and nonacademic unit managers across 140 colleges and universities. For the study, 6,357 faculty and administrators completed questionnaires that profiled their formal leader's behavior, their work group characteristics, and their personal satisfaction. Of 54 variables submitted to discriminant analysis, 31 discriminated the bureaucratic units from the academic groups. Managers of the two types of group behave differently in ways consistent with their distinct group tasks. The empirically derived role profiles of the academic and nonacademic managers are discussed, as are the implications of the findings for institutional researchers, change agents, and trainers of college managers.This article is based in part upon a paper presented at the Seventh Annual European AIR Forum, Copenhagen, Denmark, 1985. 相似文献

The monkey’s capacity to extract tonal pattern from a sequence of tones was assessed in four subjects that had the benefit of substantial past experience in discriminating, matching, and remembering acoustic stimuli. In Experiment 1, the monkeys failed to transfer their well-established matching behavior to the matching of two structured sequences of tones that differed primarily in tonal pattern, indicating that for them tonal pattern was not a salient feature of the acoustic stimuli. Experiment 2 was an attempt to encourage tonal pattern perception by employing, within a discrimination paradigm, very simple tonal patterns and multiple exemplars of the positive and negative patterns; the transfer design, borrowed from Hulse and Cynx (1985), was a powerful one for revealing tonal pattern perception. Verifying earlier results from our laboratory, there was little in the monkeys’ transfer performance to indicate that they had extracted tonal pattern from the acoustic stimuli. Major discriminative control seemed to be vested in the first tone of each exemplar. This apparent cognitive limitation may be rather general among animals, perhaps reflecting an intimate connection between the capacity for tonal pattern perception and that for acoustically based language. 相似文献
