This paper probes the extent to which education can be identified as a factor in rural depopulation. The study focuses on the Scottish Hebridean island of Raasay which has seen significant population loss since census records began in 1841. In this study the post-school destinations of all pupils enrolled at Raasay School 1901–2000 have been plotted. In addition, a sample of school pupils from 1941–2000 have been questioned about their decision-making in relation to post-school destinations. The study shows that a remarkable 86% of school pupils left the island during that century. Further education was the main reason respondents gave for migrating after leaving school but the data also suggest that it is lack of suitable employment that keeps them away. The study concludes that while education is implicated in island depopulation, of more significance is suitable employment, much more so than aspects of infrastructure such as transport and housing. 相似文献

Propensity score matching (PSM) has become a popular approach for research studies when randomization is infeasible. However, there are significant differences in the effectiveness of selection bias reduction among the existing PSM methods and, therefore, it is challenging for researchers to select an appropriate matching method. This current study compares four commonly used PSM methods for reducing selection bias on observational data from which the treatment effects are intended to be assessed. The selection bias, standardized bias and percent bias reduction are evaluated for each of the PSM methods using empirical data drawn from the national Education Longitudinal Study of 2002. The results of the current study provide empirical evidence and helpful information for researchers to select effective PSM methods for their research studies. 相似文献

This article documents the 30‐year history of communication network research at Michigan State University (M.S.U.), providing a case study of the evolution and diffusion of an academic innovation. Three past and continuing issues for network scholars are identified: a lack of professional reward for developing user‐friendly computer programs, unresolved methodological problems, and a need for better theoretical and conceptual frameworks. The narrative also illustrates the difficulty communication as a discipline has in impacting broader intellectual traditions. The story begins with the first doctoral dissertation (Schwartz, 1968) and the first network analysis software program in 1970 (Richards’ Negopy), continuing to the last dissertation (Susskind, 1996), and ending in 1998 when J. David Johnson left the M.S.U. faculty. Other major players in the M.S.U. network tradition included David K. Berlo, Eugene Jacobson, Everett M. Rogers, Vincent Farace, Peter Monge, and Erwin Bettinghaus. Ironically, Schwartz and Susskind met in 1998 while Schwartz was preparing to retire from Cornell University and Susskind was starting as an Assistant Professor in a different department, thus providing closure to the M.S.U. network. 相似文献
