Serious social media: On the use of social media for improving students' adjustment to college     

David C. DeAndrea  Nicole B. EllisonRobert LaRose  Charles SteinfieldAndrew Fiore 《The Internet and Higher Education》2012,15(1):15-23

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   

科举废止前后维新派“科举观”的转变及启示——以梁启超等为例     

陈祥龙 《考试研究》2012,(2):87-93

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   

Student Success in First-Year University Physics and Mathematics Courses: Does the high-school attended make a difference?     

Maria Adamuti-Trache  George Bluman  Thomas Tiedje 《International Journal of Science Education》2013,35(17):2905-2927

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

Hanging in or shaping a future: defining a role for vocationally related learning in a ‘knowledge’ society     

Jane Salisbury 《教育政策杂志》2013,28(1):81-104

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

衡水湖国家级自然保护区湿地景观格局演变分析   总被引：10，自引：1，他引：9  

黎聪  李晓文  郑钰  宋晓龙  曾桉 《资源科学》2008,30(10):1571-1578

基于1987年、1997年和2005年3期TM遥感数据,对衡水湖的湿地景观空间格局及其演变进行分析,结果表明：该区域以农田为景观基质,水体和芦苇沼泽交错分布构成区域湿地生境的主体斑块,其余景观类型呈以小尺度斑块散布于区域中。保护区湿地景观改变较明显,湿地由1987年的20.2%上升到1997年的23.4%,2005年占到22.3%,农田向湿地类型的转变最为显著,农田和湿地类型之间的动态转换关系很大程度上决定了保护区土地利用结构和景观格局的演变。从景观类型水平来看,表现为水体的平均斑块面积增加,由1987年的3.5187hm²减到1997年的2.0187hm²到2005年为4.3997hm²,破碎度指数下降;聚合度指数和最大斑块指数先降后升,而连接度指数先增后减;芦苇沼泽平均斑块面积下降明显,由1987年的2.6169hm²降到1997年的0.5437hm²,到2005年为0.3558hm²,且形状日趋复杂自然,最大斑块指数和聚合度指数持续减少,而连接度指数的变化趋势则相反,但总体上芦苇沼泽沼泽小面积斑块数量仍占相当比例,破碎化程度仍维持较高水平。在景观整体水平上,保护区的景观多样性和均匀度指数呈缓慢上升趋势,破碎化指数由1987年的51.068增到1997年的74.0985后2005年减为37.88,以农田为景观基质的蔓延度指数则先降后升。景观格局分析表明,衡水湖保护区湿地面积逐步恢复,破碎化程度降低且景观日趋多样化,连通性虽不及1987年历史最高水平却呈加强趋势,湿地生境质量得到优化,2005年湿地恢复的景观格局的空间配置达到3个时期的历史最高水平,也体现了保护区规划管理取得一定成效。  相似文献   

Rethinking the multi-level perspective of technological transitions   总被引：2，自引：0，他引：2  

Audley Genus  Anne-Marie Coles 《Research Policy》2008,37(9):1436-1445

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

An efficient method for parallel CRC automatic generation     

陈红胜  张维承  王勇  陈抗生 《浙江大学学报(A卷英文版)》2003,4(4):433-436

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.
