It has been long assumed that it takes some optimum size in order to obtain a sufficient critical mass to have an economy of scale operation, but there has been little substantive study of the topic. This paper looks at the relationship between enrollment and costs at colleges and universities. The question under study is whether large size provides economy of scale for operating. The question, unfortunately, is masked by the complexity of an institution. The manner in which complexity, size, costs, and enrollment interrelate is the substance of this paper. The findings suggest that curricula and complexity have an exceedingly important bearing on per-student costs.Paper presented at the Nineteenth Annual Forum of the Association for Institutional Research, San Diego, California, May 1979.  相似文献

There is a vast literature on the decision to enroll in higher education, but it focuses almost entirely on traditional students: 18 year olds graduating from high school. Yet less than half of students at degree-granting institutions are in the traditional 18–22 age range; nearly 40% are at least 25. This paper examines the enrollment behavior of persons 25 or older. We use data from a large-scale 1998 Department of Labor (DOL) policy demonstration in Greater Baltimore. By studying the behavior of older people we can examine factors such as age, earnings and marital status that vary little among the much-studied traditional students. Our results conform to the (rarely tested) predictions of human capital theory that age and opportunity costs are impediments to enrollment. We also find that where you live has a substantial impact on whether you return to school.  相似文献

This review focuses on the structuring of research models to investigate communication in intimate relationships. Two major issues addressed are: (1) the nature of outcome variables isolated for study; and (2) the need to integrate multiple theoretical perspectives to understand communication context. Suggestions are offered for defining and measuring dyadic level, instrumental, time‐bound, and evaluative communication effects. A dialectic view of communication context is presented which integrates varied perspectives for organizing and analyzing the antecedents and consequences of intimates’ communication.  相似文献

College students often use the rhetoric of individualism to explain their choice of major. Ethnographic interviews of male and female students reveal that students’ choices are gendered. Men’s decisions focus more on future earning potential and less on personal interest. Most women believe they can choose their major without concern for future income‐earning potential, because they plan to assume a traditional, feminine role of a non‐working wife and mother with a gainfully employed spouse.  相似文献

Nonfiction stories of animal compassion were used in this literacy-social studies integrated lesson to address both efferent and aesthetic stances in transmediation of text from picture books to maps. Preservice early childhood and elementary teachers chose places from the nine recent children’s stories, symbolizing them on a map while completing other map elements such as legend, index, title, and compass rose. Compassion and social-emotional skills were woven into the project by representing the affective tone of story events at various places through choice of place name adjectives. A social studies extension included analysis of how the five themes of geography were depicted on the map. Synopses of the books, one map made by first graders, and three preservice teacher-made maps, along with efferent and aesthetic elements and examples of geography themes from the maps are included. Suggestions for implementation and extension of the lesson with early elementary students are provided.  相似文献

Abstract

To evaluate the effectiveness of recovery strategies on physical performance during a 3-day tournament style basketball competition, 29 male players (mean age 19.1 years, s = 2.1; height 1.84 m, s = 0.34; body mass 88.5 kg, s = 14.7) were assigned to one of three treatment groups: carbohydrate + stretching (7.7 g · kg ?1 · day ?1, s = 1.7; ‘n = 9), cold water immersion (11°C, 5 × 1; n = 10) or full leg compression garments (18 mmHg, ~18 h; n = 10). Effects of the recovery strategies on pre–post tournament performance tests were expressed as the mean change (% ± standard deviation of the change score). Changes and differences were standardized for accumulated game time, assessed against the smallest worthwhile change for each test, and reported qualitatively. Accumulated fatigue was evident over the tournament with small to moderate impairments in performance tests. Sprint and agility performance decreased by 0.7% (s = 1.3) and 2.0% (s = 1.9) respectively. Vertical jump decreased substantially after the first day for all treatments, and remained suppressed post-tournament. Cold water immersion was substantially better in maintaining 20-m acceleration with only a 0.5% (s = 1.4) reduction in 20-m time after 3 days compared with a 3.2% (s = 1.6) reduction for compression. Cold water immersion (?1.4%, s = 1.7) and compression (?1.5%, s = 1.7) showed similar substantial benefits in maintaining line-drill performance over the tournament, whereas carbohydrate + stretching elicited a 0.4% (s = 1.8) reduction. Sit-and-reach flexibility decreased for all groups, although cold water immersion resulted in the smallest reduction in flexibility. Basketball tournament play elicited small to moderate impairments in physical test performance. In conclusion, cold water immersion appears to promote better restoration of physical performance measures than carbohydrate + stretching routines and compression garments.  相似文献
