Cohn and Farrington’s work in citation analysis has examined scholarly influence within criminological research for over 25 years. The current analysis tracks the ten most-cited scholars and each scholar’s most-cited works in four international criminology journals and six American criminology and criminal justice journals over twenty-five years and five time periods—1986–1990, 1991–1995, 1996–2000, 2001–2005, and 2006–2010. This approach extends the traditional approach to citation analysis by documenting increases and decreases in individual citation careers as well as in the most-cited scholarly contributions of the most-cited scholars during a period of significant growth in criminology. The most-cited works mostly fall within the areas of developmental and life-course criminology and criminal careers, reflecting the importance of these topics in criminology.  相似文献

Abstract

A common theme in the distance education literature is that delivery technologies with the potential for real‐time interactivity will improve both the image and practice of distance education. Although there appears to be a growing acceptance of a causal relationship between system interactivity and instructional interaction, neither concept has been clearly or functionally defined. This article discusses several systems models and relates them to the contexts of instructional delivery, instructional design, instructional theory, and learning theory in an attempt to establish conceptual parameters for the function of interaction.  相似文献

For decades American athletes in less-popular – or ‘minor’– sports suffered from a lack of institutional and practical support from their sports' governing bodies. The AAU, in particular, failed to provide the funds necessary for athletes in the sliding sports of luge and bobsled to obtain proper training and opportunities to compete. By the early 1970s, the American Olympic effort was in chaos as athletes from the Eastern Bloc, taking advantage of their nations' determination to field the best possible teams, began to excel at both the summer and winter Olympic Games. In response, Congress authorized a presidential commission to study the situation and make recommendations about how best to improve amateur sports in the United States. The result of the commission's work, the Amateur Sports Act of 1978, reorganized governance of amateur sports to the benefit, particularly, of athletes in sports such as luge and bobsled.  相似文献

Teachers’ efficacy beliefs are thought to influence not only their motivation and performance but also the achievement of their students. Scholars have therefore turned their attention toward the sources underlying these important teacher beliefs. This review seeks to evaluate the ways in which researchers have measured and conceptualized the sources of teaching self-efficacy across 82 empirical studies. Specifically, it aims to identify what can be inferred from these studies and what important questions still remain about the origins of teachers’ efficacy beliefs. Results indicate that a number of methodological shortcomings in the literature have prevented a clear understanding of how teachers develop a sense of efficacy. Nonetheless, insights gleaned from existing research help to refine, and to expand, theoretical understandings of the sources of self-efficacy and their influence in the unique context of teaching. Implications for future research and practice are addressed.  相似文献

A survey of HIV/AIDS clients in Botswana, Africa, all of whom were receiving supportive counselling, was conducted. A total of 328 volunteer clients from randomly selected sites completed the survey related to client perceptions of counselling helpfulness, outlook on life, satisfaction with goal setting in counselling, experience of social stigma, and acceptance by family and others. Overall, clients were very positive concerning the benefits received from counselling, their relationship with their counsellor, the goal setting process, their family/friends support system and their present quality of life. The majority of clients did, however, indicate some level of feeling stigmatized by being HIV-positive. Additional major findings indicated that clients with family incomes of less than 10 K pula per year (around US$1 k) were less positive about their counselling and related experiences than were those with higher levels of family income, with the exception of social stigma where lower family income was associated with less perceived social stigma. Clients reporting counselling sessions lasting more than 15 min were generally more positive in their reactions to counselling and related experiences than were clients reporting sessions typically lasting 15 min or less. A discussion of the findings, along with recommendations for areas needing further study and attention, is provided.  相似文献

This study employed a national sample of college students who initially aspired to be, or later became, physicians to determine the influence of precollege characteristics, college origins, and the academic and social experience of college on the likelihood of becoming a physician. Estimates of a 14-variable causal model indicated that the major direct effects on attainment were attributable to college characteristics and the academic experience of college. Net of other causes, the selectivity/prestige of the undergraduate institution attended, collegiate academic achievement, and majoring in the physical or life sciences each had significant direct effects on becoming a physician. The direct positive influence of college quality, however, was partially counterbalanced by its negative indirect effect. Moreover, the greatest advantage in attending an elite institution accrued to those students with relatively high levels of academic performance. As academic performance declined, so did the positive effect of college quality. The effects of precollege characteristics on becoming a physician were largely indirect, mediated by the student's college experience. Net of other factors, women were no less likely than men to become physicians, but being female had a significant negative indirect effect. Conversely, secondary school achievement did not directly influence attainment but did have a large positive indirect influence.An earlier version of this paper was presented at the annual meeting of the Association for the Study of Higher Education, San Diego, February, 1987.  相似文献
