The time doctoral students expect to take to complete their degree is investigated in a model which stresses the effects of economic factors. The model also accounts for the interdependency among such variables as employment hours, study hours, household income, and part-time study. We find that field of study, amount of borrowing, household income, and study hours have direct effects on expected time to degree. Indirect effects also occur from employment hours and the amount of fellowship, scholarship, or grant aid. When the sample is separated into foreign and U.S. students, we find that U.S. students underestimate their time to degree. Also, household incomes are higher for U.S. students and increase the time to degree, while the opposite is true for foreign students. Teaching assistantships increase the time to degree for foreign students while research assistantships reduce it. 相似文献

Schedule-induced polydipsia was studied using a behavioral contrast paradigm. Food pellets were delivered to food-deprived rats on a response-independent FT 1-min schedule. Licking on a tube produced water on a MULT FR 10 FR 10, MULT FR 10 EXT, or MIXED FR 10 EXT for three rats (Experiment 1) and on a MULT VI VI, MULT VI EXT, or MIXED VI EXT schedule for three other rats (Experiment 2). On the FR schedules, rats could drink more water by increasing lick rates, but on the VI schedules the amount of drinking was fixed by the schedule parameters and was relatively unaffected by lick rates. Relative to MULT FR FR, positive polydipsia contrast was clearly demonstrated on MULT and MIXED FR EXT; but relative to MULT VI VI, contrast was not demonstrated on MULT and MIXED VI EXT. These data suggest that polydipsia contrast occurs only if increased licking permits increased drinking. 相似文献

After a brief golden age Australian university research faces a difficult future. Two notions, utility and concentration, have become the catchwords of the emerging policy initiatives. Both have tended to be interpreted narrowly and simplistically, utility as having immediate technological applications that will bring economic benefits, and concentration to argue for breaking the teaching-research nexus, reducing the research workforce and thus achieving cost savings. As proposed, both initiatives require more centralised control of research policy and funding. Despite the outstanding record of Australia's universities in research and the absence of evidence to support the benefits claimed for the new initiatives, the pressure for change is gaining momentum. The problems facing Australian universities have much in common with those in other Western countries, although unique solutions must be sought for every setting. This paper argues that, in Australia, the adoption of the easy solution of increased concentration, short-term utility, and centralised control, is likely to compromise the established excellence and diversity in basic research, and to lead to an overall reduction in the scale of university research. Before any changes are instigated, there is a pressing need for a broad-ranging review based on widespread participation in a debate about needs and priorities, and rigorous research into the performance of the existing system and the potential benefits of the changes proposed. 相似文献

One-thousand two-hundred and ninety university students from twenty-seven ethnic?national groups across six locations in the former Soviet Union (Novopolotsk in Byelorussia, Kharkov in the Ukraine, Moscow and Nizniy Novgorod in Russia, Ufa in the Bashkir Autonomous Republic and Ulan-Ude in the Buryat Autonomous Republic) participated in 1991–1992 in a survey investigating the existence of ingroup preference in inter-ethnic contact, ingroup consensus on an ethnic hierarchy of outgroups and the measure of intergroup consensus on an ethnic hierarchy among the ethnic?national groups in each location. Hypotheses about ingroup preference, ethnic hierarchies and consensus were derived from realistic group conflict theory, social identity theory and from the assumption that outgroup preferences reflect considerations of the status effects of intergroup contact. It appeared that the last type of hypothesis could explain most of the results. 相似文献

Postsecondary institutions in the United States, including member institutions of the National Collegiate Athletic Association (NCAA), are charged with the responsibility of cultivating positive learning environments where all students have an opportunity to excel regardless of their demographic backgrounds (e.g., race, socioeconomic status, etc.). However, one subgroup of students these institutions have persistently been unable to retain and graduate at rates comparable to their peers is Black male student athletes. Previous research has cited unwelcoming campus climates, inadequate academic support, and an overemphasis on athletics as key factors that contribute to Black male student athletes' academic underperformance and negative psychosocial experiences at these institutions. The purpose of this article is to present a series of strategies and recommendations for enhancing Black male student athletes' educational experiences and holistic development at postsecondary institutions in the U.S. A review of scholarly literature on Black male student athletes, college student development theories, and student athlete support programs was conducted to identify best practices related to the phenomena. An analysis of the literature led to the creation of the Excellence Beyond Athletics (EBA) approach. The EBA approach consists of the following six holistic development principles (HDPs): (1) self-identity awareness, (2) positive social engagement, (3) active mentorship, (4) academic achievement, (5) career aspirations, and (6) balanced time management. 相似文献
