Advocates of market-based education reform hypothesize that competition will cause traditional public schools to increase outreach efforts as they seek to market themselves. Advocates hope such efforts will result in more information on school activities and performance and thereby enhance accountability. We examine the effect of charter school competition on outreach efforts by a sample of 98 Arizona district schools, finding that charter competition is associated with a short-term increase in outreach. Organizational structure influenced school response, with more decentralized district schools responding more readily to charter competition. Competition modestly increased information regarding schooling in the short run, although long-term implications are less clear.  相似文献

This paper outlines work currently being undertaken to reconstruct submerged archaeological landscapes off the north coast of Ireland. This research uses the recently‐completed Joint Irish Bathymetric Survey (JIBS), which has provided full‐coverage high‐resolution multibeam bathymetric data for the sea‐bed off the north coast. This data has been examined for evidence of past sea‐level change and been used to produce palaeo‐geographic reconstructions of the past landscape, which in turn have facilitated the identification of ten areas of high archaeological potential. The results presented here will form the basis of a future programme of archaeological survey and prospection. © 2010 The Authors  相似文献

In 2019, we returned to Karavar, one of Papua New Guinea's Duke of York Islands. Since our last visit 28 years earlier, many with whom we worked had died. However, their children knew about us and were eager for our recollections about the lives and times of their parents. We, in turn, wished to learn about current lives and times. Our conversations, thus, often focused on multi‐generational changes. Significantly, most Karavarans thought that these changes had been for the better. Indeed, they seemed relatively satisfied with their present circumstances. In contrast, the Karavarans we had earlier known were frequently fired up with grievance, disappointment, possibility, and occasional exultation. Here we consider how contentiousness turned into contentment; how, what Karavarans had been, approached what they wanted to be. In understanding this historical process, we consider several ramifying ‘events’: happenings that Karavarans recognized, whether immediately or in retrospect, as interrupting business as usual and, ultimately, as challenging assumptions about the workings of their world.  相似文献
