Communities with high levels of social capital are likely to have a higher quality of life than communities with low social capital. This is due to the greater ability of such communities to organize and mobilize effectively for collective action because they have high levels of social trust, dense social networks, and well-established norms of mutuality (the major features of social capital). Communities with “bridging” social capital (weak ties across groups) as well as “bonding” social capital (strong ties within groups) are the most effective in organizing for collective action. People who belong to multiple groups act as bridging ties. When people with bridging ties use communication media, such as the Internet, they enhance their capability to educate community members and to organize, as needed, for collective action. This article summarizes evidence from stratified household survey data in Blacksburg, VA, showing that people with weak (bridging) ties across groups have higher levels of community involvement, civic interest, and collective efficacy than people without bridging ties among groups. Moreover, heavy Internet users with bridging ties have higher social engagement, use the Internet for social purposes, and have been attending more local meetings and events since going online than heavy Internet users with no bridging ties. These findings may suggest that the Internet—in the hands of bridging individuals-is a tool for enhancing social relations and information exchange, and for increasing face-to-face interaction, all of which help to build both bonding and bridging social capital in communities. 相似文献

Patent data have been widely used in research to characterize firms’ locations in technological or knowledge space, as well as the proximities among firms. Researchers have measured firms’ technological or knowledge proximities with a variety of measures based on patent data, including Euclidean distances (using the technological classifications listed on patents), and overlap in cited patents. Often research has employed only the first listed patent classification in measures of proximities. We explore the effects of using the first listed patent class as well as other methods to measure proximities. We point out that measures of proximity based on small numbers of patents are imprecisely measured random variables. Measures computed on samples with few patents or a single patent class generate both biased and imprecise measures of proximity. We discuss the implications of this for typical research questions employing measures of proximity, and explore the effects of larger sample sizes and coarser patent class breakdowns in mitigating these problems. Where possible, we suggest that researchers increase their sample sizes by aggregating years or using all of the listed patent classes on a patent, rather than just the first. 相似文献

Signature pedagogies [Shulman, L. 2005. “Signature pedagogies in the professions.” Daedalus 134 (3): 52–59.] are a focus of teacher educators seeking to improve teaching and teacher education. The purpose of this paper is to present a preliminary common language of signature pedagogies for teacher professional development (PD). In all, 24 papers from the study of physical education PD projects with clearly articulated pedagogical objectives and documentation on achieving those objectives were included in the analysis. In total 479 teachers and 48 facilitators across the US and Europe were interviewed and/or surveyed. Three discrete PD signature pedagogies holding potential to enhance teacher growth and learning within the context of PD were identified: critical dialogue (process of acquiring knowledge through communicative interactions), public sharing of work (testing out practices in classrooms and share ideas with larger audiences), and communities of learners (collective learning around a shared concern or a passion). It is our hope in providing the beginnings of a common vocabulary for pedagogies of teacher professional learning we have encouraged additional steps toward developing signature pedagogies for learning across different PD settings and content areas. 相似文献

This article examines students’ experiences as resettled refugee and asylee students in international schools in New York City. Specifically, it looks at how teachers and school leaders provide critical academic and extracurricular support to facilitate students’ adjustment to academic environments that differ markedly from those compared in their countries of origin or the countries of asylum visited prior to their arrival in the United States. Drawing on a qualitative study conducted in New York City at two international schools, as well as program staff from an outside organization that often collaborates with international schools hosting refugee and asylee students, the article documents promising practices and offers practical recommendations for teachers working with refugee students. 相似文献

With increasing use of the World Wide Web, rapid scanning or skimming of material on screen has become a frequent activity. However, the outcome of this method of reading has not been thoroughly investigated. Using a range of question types, comprehension was measured after reading from screen at both a normal and fast reading speed. In addition, by automatically recording how readers scrolled through each document, reading patterns were explored. A speed‐accuracy trade‐off was found and, in general, the recall of specific details was less accurate than responses to ‘higher order’ questions. However, questions that addressed the structure of the text were hardest. Analysis of the scrolling movements showed that the overall time spent pausing between movements was the best predictor of comprehension. At a normal reading speed, the most effective readers, in terms of higher comprehension scores, were those who spent more time between scrolling movements, which were fast and frequent. 相似文献

The number of older adults taking advantage of courses offered by institutions of higher learning is increasing. Despite this trend in university and college enrollment, educators know little about the reasons why adults aged 55 years and over are making the decision to return to school. This paper describes the results of an exploratory study about: (1) educational motivations of older students; (2) effect of involvement in university classes on older adults' attitude toward aging; and (3) impact of older individuals' participation in university classes on marital relations. Interviews were_ conducted with twenty‐one married couples, aged 55 years and older (X = 68.54), with one spouse attending university classes. In order to compute life satisfaction analyses, a control sample was secured. This group consisted of 33 married couples, 55 years and over (X = 70.93), with neither spouse participating in continuing education. Results indicated that older students viewed intrinsic learning goals to be significantly more important than extrinsic incentives (p<.01). Student couples reported significantly more positive attitudes toward growing older than did nonstudent couples (p<.05). Although participation in university classes had only a minimal impact on members' marital interaction, student couples express satisfaction with this effect. Recommendations suggested the construction of assessment measures of older adults' self‐initiated versus externally reinforced learning goals. It is advised that pre‐ and posttest interview schedules be used when determining the impact on family solidarity of older adults' pursual of further learning. Future research is suggested which explores whether participation in continuing education provides skills or information for older persons to adjust to their changing environments which in turn would have an influence on level of morale. 相似文献

Rural colleges and universities in the USA struggle to recruit new students, as their geographic region is depopulating and costs to attend classes on campus are increasing. Online education using the Internet is rapidly expanding as an effective growth strategy to reach new groups of students. In this paper, we take the position that online education is a form of cultural imperialism and academic capitalism where curriculum developers and professors are motivated to enroll new students in order to maintain the credibility and strength of their programmes and host institutions. We argue that it is not our intent to be educational imperialists or capitalists. Rather these are unintended consequences of our actions. This argument is supported by political economy theory in that we are marketing a technical rational form of online education without awareness of its long-term cultural, economic or political ramifications. Even though we pride ourselves on developing a high-quality programme that in our eyes meet the needs of our students, understanding the political economy of online education is essential if our programme that has access to the global market is to go beyond the individual needs of students and address social, cultural and political needs. We conclude that one way out of this malaise is to understand our role as instructors and course designers as a first step towards understanding the intended and unintended consequences of online education. 相似文献

The purpose of this study was to determine how well former employees at a television glass manufacturing plant were able to find employment in a new field of study following graduation from a local community college. The majority of participants were able to find reemployment, albeit at a lower salary. In addition, information was obtained regarding the level of satisfaction with participants' new jobs and perceived barriers faced while looking for employment. 相似文献
