A considerable body of research indicates that social support plays an integral role in determining students' successful adjustment to college. Unlike previous research that has evaluated face-to-face support interventions that occur during students' first semester at college, the current study reports on a student-centered social media site designed to enhance students' perceptions of social support prior to their arrival on campus. Results indicated that site usage increased students' perceptions that they would have a diverse social support network during their first semester at college, even when controlling for other potent predictors. The importance of social support perceptions for college adjustment is detailed and the ramifications of the social media intervention are discussed. 相似文献

科举制度废止前后,维新派的一些领袖人物对待科举的态度发生了明显的变化,梁启超是其中的著名代表。晚清时期,他们从不同的角度对科举制度进行了批判,推动了科举制度的废止。制度废止以后,鉴于对当时社会现象以及西学了解的加深,他们对科举制度又进行了重新的合理评价。这种转变过程打上了深深的时代与个人烙印,反映了他们随着社会发展对科举制度存与废的理性思考。 相似文献

This paper considers school factors that contribute to a successful transition from high school to first-year university Physics courses at the University of British Columbia by employing a two-level hierarchical model. It is assumed that there is a relationship between student performance and the high school they graduated from. It is shown that school location and type affect student performance: students from public schools in the Metro Vancouver area perform better in first year compared to students from independent schools and schools in distant communities. The study also considers rankings of schools based on student performance in first-year university Physics and Calculus courses. These university-based rankings differ significantly (essentially in reverse order) from the well-known Fraser Institute rankings based on measures internal to high schools. 相似文献

This paper explores the ‘joined‐up thinking’ and attempts at ‘joined‐up working’ that policy architects recommend for the successful operationalization of the New Deal for 18–24 year olds. In particular, it examines the difficulties arising around the full‐time education and training option. The research project reports upon the ‘implementation gaps’, in particular the workings of Employment Service Personnel and College staff who strive to interpret and work within the relevant policy guidance for the New Deal for Young People (NDYP). The paper draws upon semi‐structured interviews and documentary analysis from a qualitative case study in South Wales to describe the interaction and articulation of the ‘main players’ who facilitate New Deal education and training options. Centralized and mandatory programmes like the New Deal for Young People which aims to be integrative and ameliorative, but which are framed within a strong sanctioning policy, have created tensions between those professionals trying to work in a ‘joined‐up’ manner. The guidance, educative, and social work elements which contribute to a positive learner/trainee identity are at odds with the surveillance and policing roles involved in monitoring claimant participation. FE staff who facilitate and manage the ‘New Deal’ full time education and training option emerge as a seriously challenged group, which has to forge workable and practical applications of a policy which somewhat undermines notions of a learning society and lifelong learning. 相似文献

In recent years numerous articles have been published which advocate a multi-level perspective (MLP) for the analysis of long-term technological transitions. This paper reviews current transitions research and considers the limitations of the MLP which need to be addressed to enhance understanding of processes of innovation affecting the transformation of technology and society. The paper suggests ways in which the MLP may be effectively rethought, based on more thoroughgoing application of a co-evolutionary concept of technological transitions. 相似文献

目的:初步探讨"高原-亚高原-平原"过渡训练对世居高原的中长跑运动员心肺功能的影响.方法:通过对18名甘孜州世代居住在海拔2 500m以上的中长跑运动员在高原训练后进行"高原-亚高原-平原"过渡训练,训练结束后分别在高原、亚高原、平原分别采集其与心肺功能相关的生理生化指标,对高原-亚高-平原过渡训练对世居高原的中长跑运动员心肺功能的影响进行初步研究.结果:经分析发现训练结束后测得从康定到泸定再到都江堰的最大摄氧量、血乳酸、血氧饱和度、尿蛋白均呈递增趋势,心率呈递减趋势,且除尿蛋白外各项指标均存在显著性差异(P<0.05).结论:高原-亚高原-平原过渡训练有利于提高世居高原中长跑运动员的心肺功能的适应能力.提示:高原-亚高原-平原过渡训练心肺功能的变化有利于运动员更快更好的适应从高原到平原的海拔落差,对运动员训练时运动强度的提升和成绩的提高提供运动生理学依据. 相似文献

The State Transition Equation (STE) based method to automatically generate the parallel CRC circuits for any generator polynomial
or required amount of parallelism is presented. The parallel CRC circuit so generated is partially optimized before being
fed to synthesis tools and works properly in our LAN transceiver. Compared with the cascading method, the proposed method
gives better timing results and significantly reduces the synthesis time, in particular.
