The research described here comprised a pilot study that attempted to identify the factors in decisions of highly capable students from underrepresented minority groups to forego study for science or engineering doctorates. Underrepresented students are defined as Blacks, Hispanics, and Indians. While these groups will soon comprise 30% or more of the population, they receive only 5% of the S & E (Science and Engineering) doctorates. The research was completed under NSF (National Science Foundation) grant no. REC 9908861. The research built on a previous NSF study (RED-9355867) that identified the most effective colleges and universities in the country in the preparation of Black, Hispanic, and Indian science and engineering students for study toward the PhD degree. One of the major concerns raised during the site visits to the top 10 institutions serving these groups was the loss of capable students to other careers. The study obtained information from minority graduates about factors impacting persistence to graduate studies in science and engineering and solicited suggestions for attracting more people like themselves to S & E doctoral study. Twelve underrepresented minority S & E graduates who decided to forego doctoral study in favor of other pursuits. Themes emerging from these conversations regarding reluctance to pursue advanced study included the following: concern for ability to finance such study; weaknesses in advisement practices and systems; lack of full knowledge, early on, about the rewards of doctoral employment; and concern about opportunities for employment after graduation. Suggestions proffered for attracting more underrepresented minorities to S & E doctoral study included the following: early socialization of youngsters into the world of science and its practice; expanded funding for scholarships and fellowships; expanded outreach by colleges and universities; expanded efforts by churches and community groups and deeper commitments by colleges and universities.  相似文献

This article describes a small‐scale exploratory study in which young children were taught to think aloud as they read, revealing some of their thought processes as they made sense of the text. The children spontaneously made predictions, adjusted their understanding, entered imaginatively into the characters' feelings and related their reading to events in their own experience. They had difficulty, though, in appreciating a surprise ending. The think‐aloud method proved fruitful for research purposes and could offer valuable insights to teachers.  相似文献

Food-deprived rats develop polydipsia on an intermittent schedule (fixed time 60 sec) of food pellet delivery, but not on an identical schedule of food powder delivery. This result was demonstrated with separate groups receiving each type of food and was replicated using rats as their own controls. Powdered food not only prevented the development of polydipsia, but it abruptly terminated ongoing polydipsia in rats that were switched from the scheduled delivery of pellets to powder. Ethological analysis of the behavior showed that the rats receiving powder were not engaging excessively in some behavior other than drinking. After discounting several factors, we concluded that the amount of oral activity associated with feeding, which occurred immediately after food delivery, was reciprocally related to the level of drinking.  相似文献

This study uses discourse analysis to examine the representation of violence against African American women in local TV news coverage of Freaknik, an annual “spring break” ritual that drew African American college students from throughout the country to Atlanta, Georgia in the 1990s. It draws on Black feminist theory in its examination of the ways that gender, race, and class intersected to shape the representation of the victims, the perpetrators, and the violence. The results indicate that the convergence of gender, race, and class oppressions minimized the seriousness of the violence, portrayed most of its victims as stereotypic Jezebels whose lewd behavior provoked assault, and absolved the perpetrators of responsibility. Coverage also reinforced race and class stereotypes by representing locals as underclass troublemakers prone to crime while students were linked to law‐abiding, middle class values and norms. In demonstrating the utility of addressing the intersectionality of gender, race, and class, this study argues that such an approach is necessary to the study of representation.  相似文献

Abstract

This study focuses on a novel, easy to use and instruction-less method for mental training in athletes. Previous findings suggest that particular mental capacities are needed for achieving peak performance; including attentional control, focus, relaxation and positive affect. Electroencephalography (EEG) alpha brain activity has been associated with neural inhibition during processes of selective attention, for improving efficiency in information processing. Here we hypothesised that eyes open alpha power training by music teaches athletes to (1) learn to self-regulate their brain activity, and (2) learn to increase their baseline alpha power, herewith improving mental capacities such as focusing the allocation of attention. The study was double-blind and placebo-controlled. Twelve elite gymnasts were either given eyes open alpha power training or random beta power training (controls). Results indicate small improvements in sleep quality, mental and physical shape. In our first attempt at getting a grip on mental capacities in athletes, we think this novel training method can be promising. Because gymnastics is one of the most mentally demanding sports, we value even small benefits for the athlete and consider them indicative for future research.  相似文献

Increasing MSW students’ information competencies was achieved through a 2-year project in which online video tutorials, in-class exercises, and course assignments were created and integrated into two required foundation courses. Tutorials demonstrated basic and advanced search techniques, online databases, and online course-specific research guides. Tutorials were viewed during and outside of class. In-class exercises and course assignments enabled students to immediately apply what they had learned. Results indicate a significant increase in the adequacy of students’ search for online information and ability to critically examine sources and evidence. Implications for social work education are discussed.  相似文献
