This article describes how the National Science Foundation's support of information research has evolved from NSF's original mission of improving the dissemination of scientific and technical information to its present interest in information robotics and intelligent systems. The pattern of grant support, since a major reorganization of the information science division in 1978, is analyzed in terms of the institutions, the investigators, and the disciplines that have been major grant recipients. 相似文献

The vast majority of American middle schools and high schools sell what is known as "competitive foods", such as soft drinks, candy bars, and chips, to children. The relationship between consumption of sugar-sweetened drinks and snacks and childhood obesity is well established but it remains unknown whether competitive food sales in schools are related to unhealthy weight gain among children. We examined this association using data from the Early Childhood Longitudinal Study Kindergarten Cohort. Employing fixed effects models and a natural experimental approach, we found that children's weight gain between 5(th) and 8(th) grades was not associated with the introduction or the duration of exposure to competitive food sales in middle school. Also, the relationship between competitive foods and weight gain did not vary significantly by gender, race/ethnicity, or family SES, and remained weak and insignificant across several alternative model specifications. One possible explanation is that children's food preferences and dietary patterns are firmly established before adolescence. Also, middle school environments may dampen the effects of competitive food sales because they so highly structure children's time and eating opportunities. 相似文献

Conclusion Small presses are a colorful and wildly variegated lot. They offer materials on every imaginable topic to suit almost any
taste and are springing up in towns and hamlets all over the country. New presses are being founded at a furious rate, though
their ability to survive is as yet unknown. Clearly, many presses exist for other than purely commercial reasons. Our analysis
suggests that only about a sixth of the 1700-odd publishers for which we have data are serious commercial enterprises; well
over half, perhaps as many as two-thirds of them, exist for other reasons—personal interests, hobbies, or special causes. 相似文献

The authors attempted to gain an understanding of critical incidents (CIs) from the perspective of novice counselor trainees during their 1st year of supervised clinical practicum. Journals kept by 9 trainees in master's‐level counseling programs were qualitatively analyzed using the discovery‐oriented research methodology (A. Mahrer, 1988). One hundred fifty‐seven CIs emerged in 5 major categories: (a) professional identity, (b) personal reactions, (c) competence, (d) supervision, and (e) philosophy of counseling. Implications of the findings are discussed for counselor development theory and research, as well as counselor training. 相似文献

In social work, it is believed that certain knowledge and skills are learned more effectively through experience than through didactic classroom content. Members of the faculty of a school of social work have developed a Social Action Day to reinforce curriculum and translate into practice material about advocacy and ethical responsibilities for social action; show the breadth of social work practice; and enhance the school's sense of community. The authors share their experience to inspire other social work faculty, so that they are better able to foster student interest and passion for political action that may generate social change. 相似文献
