大学计算机基础课程教学改革与资源建设探析——以成都理工大学为例

成都理工大学计算机基础课程教学经历了一个从分散到统一的改革过程,并取得了明显的成效,但也存在一些问题.针对这些问题,只有进一步明确课程定位、精讲课程内容、创新实验教学和考核方法,同时加快立体化教材建设,有效开拓和使用网络教学资源,才能更有效推动该门课程教学水平的提高.     

Analysing non-doctrinal socialization: re-assessing the role of cognition to account for social cohesion in the Religious Society of Friends

To incorporate newcomers into membership, a group employs socialization strategies to transform the characteristics of the newcomers, so that it can admit them with the confidence that their behaviour will not endanger group unity. Analyses of socialization emphasize that novices' interiorization of an institutional definition of group behaviour is a necessary condition to ensure successful socialization. The contemporary Religious Society of Friends in Britain, however, is a non-doctrinal religious movement that avoids defining the content of its beliefs and practices. To analyse the socializing interaction between members and newcomers in this movement in Britain, and among co-religionists in the USA, this inquiry applies a model of socialization that does not include assumptions about the role played by cognition in socialization (Long and Hadden 1983). My results show that: (a) the diffuseness in Friends' collective explanations of institutional conduct supports novices' identification with institutional practice, and (b) experimental and affective components in socialization motivate novices to imitate institutional behaviour despite the fact that Friends have no authoritative explanations of such behaviour. The data suggest that socialization and social cohesion are not necessarily as strongly cognitive-oriented phenomena as they were previously thought to be. This finding has important implications for thinking about social cohesion in postmodern society.     

神话资源转化必须警惕两种倾向——冯天瑜先生访谈录

冯天瑜先生认为:神话资源转化与其他传统的、古典的资源转化一样,具有文化延续的必然性;神话资源转化过程有一个诠释学问题,在诠释学范畴内讨论神话资源转化,必须警惕两种倾向,一是过度诠释,二是否定诠释的可能性;神话资源转化既要坚持资源的本真性,又要坚持资源在当代的可转化性,只有如此,神话资源转化方能产生积极的文化影响。     

建筑材料资源的可循环利用

现代建筑是能源及材料消耗的重要组成部分,随着地球环境的日益恶化和资源日益减少,保持建筑材料的可持续发展,提高建筑资源的综合利用率已成为社会普遍关注的课题。欧美等发达国家对建筑材料资源的保护与可循环利用问题意识较早,已开展大量的研究与广泛的实践,如传统建筑材料的可循环利用、一般废弃物在建筑中的可循环利用及新型可循环建筑材料的应用等等,且大多由政府主导,以"自上而下"的方式形成对建筑资源保护较一致的社会认同。目前,我国对建筑材料资源可循环利用的研究已取得突破性成绩,但仍存在技术及社会认同等方面的不足,中国与发达国家在该领域还存在差距。

Exploring the link between government funding and efficiency in nonprofit colleges

Previous literature has suggested that federal funding can hinder the efficiency of nonprofit organizations, but this has yet not been empirically tested. This study used a two‐stage data envelopment analysis (DEA) model to measure the efficiency of a set of private nonprofit teaching‐oriented colleges, then estimate the impact of federal and state funding on organizational efficiency. The findings indicate that, on average, increases in neither state nor federal funding effect efficiency of nonprofit colleges. Increasing state funding negatively impacted the efficiency of public colleges (N = 799). This study suggests that the challenges for nonprofits that accompany government funding may not rise to a quantifiable negative effect on efficiency.     

基于最大收益的无线虚拟网络重映射算法

针对无线环境的动态性及虚拟网络请求到达与离开的随机性,使得物理网络负载分布不均衡,导致后续请求的接受率降低的问题,提出一种无线网络虚拟化中的两阶段重映射算法（two stages reconfiguration scheme for wireless network virtualization,TR-WNV）。该算法通过第1个阶段选出合适的虚拟网络进行重映射,接着在第2个阶段按照优先级对已选出的虚拟网络进行重映射,并根据离散度来判断每次映射效果。最后,通过仿真对算法进行验证,结果表明该算法在保证虚拟网络请求收益最大化同时,有效提高了虚拟网络请求接受率,实现整个底层网络的负载分布均衡。     

When is brokerage negatively associated with economic benefits? Ethnic diversity,competition, and common-pool resources

There is a growing body of literature positively linking dimensions of social capital to economic benefits. Yet recent research also points to a potential “dark side” of social capital, where over-embeddedness in networks and the pressures associated with brokerage are hypothesized to constrain actors, having a negative effect on economic outcomes. This dichotomy suggests that context is important, yet the overwhelming majority of existing empirical evidence stems from socially homogenous populations in corporate and organizational settings, limiting a broader understanding of when and how context matters. We advance this discourse to a socially fragmented, ethnically diverse common-pool resource system where information is highly valuable and competition is fierce. Merging several unique datasets from Hawaii's pelagic tuna fishery, we find that network prominence, i.e., being well connected locally, has a significant, positive effect on economic productivity. In contrast, we find that brokerage, defined here as ties that bridge either structurally distinct or ethnically distinct groups, has a significant, negative effect. Taken together, our results provide empirical support to widespread claims of the value of information access in common-pool resource systems, yet suggest that in ethnically diverse, competitive environments, brokers may be penalized for sharing information across social divides. Our results thus contribute to an emerging theory on the fragile nature of brokerage that recognizes its potential perils and the importance of context.
