This paper describes our efforts to systematically generate knowledge from ethnographic and other qualitative scholarship as a way of bridging intellectual gaps found in quantitative research. We ground this scholarly endeavor in the study of gangs, which has a lengthy history in the field of criminology, yet lacks a coherent, coordinated, and comparative understanding of gang dynamics, behavior, and impacts. We discuss the importance of acknowledging the multiple and mixed methodologies used in gang scholarship and detail the inductive, deductive, and iterative process that helped us (1) develop a comprehensive coding instrument for coding a range of qualitative works, (2) establish the instrument’s inter-rater reliability, and (3) remain cognizant and reflexive about the strengths of both quantitative and qualitative research. Finally, we share the critical yet informative challenges we faced throughout the project and conclude with reflections on why the project was unsuccessful in the way we originally envisioned.  相似文献

The concept of social capital, and its role in the development of political stability and economic growth, has become a topic of increasing interest in state, business and community sectors alike. Within this body of discourse, though, it is generally assumed that the influence of social capital is from the ‘outside-in’: that social capital is generated within institutions of civil society and is beneficially utilized by private and public sector organizations. Through a case study of a South African industrial organization, this paper provides an example of ‘inside-out’ influence where social capital generated by collaborative forms of social organization at the workplace, is distributed across family and community structures. The authors argue that this process, whereby civil society becomes a beneficiary of social capital produced in business and industrial workplaces, offers new policy options for social renewal especially within societies that have subjected to civil unrest and/or prolonged periods of oppression of some kind.  相似文献

Abstract

The purpose of this investigation was to determine the extent to which computers assist high school students in learning English language vocabulary. The experience describes an experimental investigation conducted in a Teacher‐Training Practising Secondary School in Cameroon on the use of computer‐assisted software to teach English vocabulary. Specifically, the major thrust of this investigation was to compare the effects of using computers in the teaching of English language vocabulary with the conventional method of teaching. Students were split into two groups: an experimental group and a control group. The latter group received the conventional method while the former group was given the computer software application. Results indicated that there was very little significant difference in the academic performance of both groups. However, the experimental group demonstrated positive attitudes toward a computer and the software program.

Abstract français: Le but de cette recherche était de déterminer jusqu'o[ugrave] les ordinateurs peuvent aider des étudiants d'école secondaire à apprendre le vocabulaire anglais. L'article décrit la recherche conduite dans un institut de formation des maîtres du second degré au Cameroun sur l'utilisation de logiciels pour l'enseignement du vocabulaire anglais. En fait, l'objectif majeur de cette recherche était de comparer les effets de l'emploi des ordinateurs à cette fin avec les méthodes traditionelles de formation. On a divisé les étudiants en deux groupes: expérimental et contrôle. Ce dernier a reçu cette formation traditionelle, tandis que le premier a subi des applications de logiciels. Les résultats ont montré qu'il n'y avait pas de différence significative entre les performances des deux groupes. Cependant, le groupe expérimental a fait preuve d'attitudes positives envers l'ordinateur et les programmes de logiciels.  相似文献

This paper responds to the fourth annual report by W. John Minter and Howard R. Bowen on Independent Higher EducationFinancial and Educational Trends in Independent Higher Education, 1978. Primary thesis: established financial reporting does not tend to do justice to a sound assessment of the financial condition of colleges and universities. Because the latter belong to the service economy, we must know more than we do about changes in quality. Such studies also must say how well institutional objectives are being achieved. College presidents and deans have tended to provide researchers with overly optimistic information. When they later see that Bowen and Minter report this very fact, they complain that their conclusions are not gloomy enough. Such double standards damage realistic program assessment efforts. The blame falls on the respondents and not on the authors. Neither can the authors be blamed for shortcomings in financial accounting ignoring the total cost of institutional activity. If accounting practice were based on a total cost concept the news about higher education finance would more nearly reflect what we all know is true: colleges and universities are worse off than the statistics say.Presented at the Annual Forum of the Association for Institutional Research, Houston, Texas, May 1978.  相似文献

Prestigious professional organisations have questioned the efficacy of resistive training by children or have often neglected to address weightlifting in their position papers on resistive training for children. The purpose of this paper was to address the deficit in data regarding the efficacy of training children for weightlifting and to report data regarding to safety in this population. Eleven subjects (3 female, 8 male) who had trained at the USA Weightlifting Development Centre in Shreveport Louisiana for a minimum of 22 months (mean = 28.8; SD +/- 4.4) served as subjects for this study. Means for the pool of subjects subjected to t-test to compare data obtained at each subject's initial competition with that obtained at the individual's most recent competition revealed significant positive changes in body weight, snatch weight, clean and jerk weight, and total weight lifted. The latter three were significant both in absolute weight and in weight lifted per kg of body weight. Total weight lifted at competitions plotted separately for boys and for girls across time indicated an apparently steeper slope of improvement for boys. The latter were not tested for significance because of the small sample sizes. The lack of injury in training and in 534 competitive lifts was discussed. None required medical attention or loss of training time. It was concluded that there can be no doubt regarding the efficacy of weightlifting as carried out at the USA Weightlifting Development Centre. The importance of proper application of scientific theory of conditioning in a conservative manner for this population was emphasised.  相似文献

At the Butcher Shop, a steakhouse in downtown Memphis, a banquet-size table is crowded with people who are all somehow asso-ciated with Justin Timberlake: his mother and stepfather, Lynn and Paul Harless (who co-manage his career), his best friend's girlfriend, his publicist, some family friends, business asso-ciates, me. We pass our time laughing and drinking wine and eating filet (鱼片) mignon and twice-baked potatoes, but we're really just waiting  相似文献

This paper identifies salient practices of faculty mentors of undergraduate research (UR) as indicated in the extensive literature of the past two decades on UR. The well-established benefits for students involved in UR are dependent, first and foremost, on high-quality mentoring. Mentorship is a defining feature of UR. As more and different types of colleges and universities strive to meet student demand for authentic scholarly experiences, it is imperative to identify what effective UR mentors do in order to ensure student engagement, quality enhancement, retention, and degree-completion. We offer an original analysis of the literature on UR mentoring in which we identify 10 significant “lessons learned,” or evidence-based practices of effective UR mentors that apply broadly across disciplines, students, institutions, and mentoring approaches.  相似文献
