Like a tree

The contemporary mediascape has been marked by a proliferation of popular TV genres in which the public appear as central protagonists. These genres are part of a broader shift in the relationship between media and audiences which challenges traditional conceptions of public service broadcasting and appear to represent a shift from media as public knowledge to media as constituting a space for diffuse popular engagement. A central feature of this shift has been the growing role of popular forms of expertise on television. This paper maps the main critical debates around participatory television and the role of the expert, from earlier work on talk shows to more recent discussions of reality and makeover TV. It notes a transition within the critical media and cultural studies literature from a focus on public sphere theory and questions of democratization to a growing concern with the role played by popular media culture in supporting new modes of governance based on the expert mediation of normative self-control. In this paper we analyze the role of experts on Oprah Winfrey's popular website Oprah.com, noting both the utility and limitations of a governmental perspective. Extending upon Foucault's notion of the productive nature of liberal subjecthood, the paper suggests the more positive role played by popular expertise in contributing to a media–civic culture articulated to a politics of recognition.     

论李大钊对马克思主义信仰的认同逻辑

李大钊对马克思主义的认同是近代中国人接受和认同马克思主义过程中的一个典型案例。研究李大钊认同马克思主义的行为,搞清楚李大钊为什么认同马克思主义,怎样认同马克思主义,以及认同什么样的马克思主义这些基本问题,对于从主体和感性方面理解马克思主义在中国社会的全面兴起具有重要意义。     

Lineup Identification by Children: Effects of Clothing Bias

This study examined effects of clothing cues on children's identification accuracy from lineups. Four- to 14-year-olds (n = 228) saw 12 video clips of individuals, each wearing a distinctly colored shirt. After watching each clip children were presented with a target-present or target-absent photo lineup. Three clothing conditions were included. In 2 conditions all lineup members wore the same colored shirt; in the third, biased condition, the shirt color of only one individual matched that seen in the preceding clip (the target in target-present trials and the replacement in target-absent trials). Correct identifications of the target in target-present trials were most frequent in the biased condition, whereas in target-absent trials the biased condition led to more false identifications of the target replacement. Older children were more accurate than younger children, both in choosing the target from target-present lineups and rejecting target-absent lineups. These findings suggest that a simple clothing cue such as shirt color can have a significant impact on children's lineup identification accuracy.     

新闻从业者的媒介角色认知--兼论舆论监督的记者主体作用

调查表明,在上海这个国内经济活动最为活跃、舆论监督却乏善可陈的城市,"以天下为己任"的道德传统,依然是今天的新闻从业者个人价值体系中的重要底色。对于大多数新闻从业者来说,选择从事新闻工作,更多地是出于对大众传播媒介所能够担负起重要的社会道义责任的向往,同时也出于自身的兴趣爱好。至于对名利的追逐,显然并不是选择新闻业的首要因素。这一点,正是记者作为正在走向专业化的个体,在新闻媒介实行舆论监督当中发挥作用的重要思想基础。

Regulation in Comparative Perspective

Structural changes in the world economy pose challenging new problems for comparative policy analysis. One such problem is the harmonization of domestic policies and institutions, which the Uruguay Round of GATT negotiations has identified as a key principle of international economic relations. Harmonization may mean the creation of a single policy space out of a number of distinct jurisdictions. It can also mean the adoption of common policy goals or general principles that national governments can pursue by different strategies. Comparative analysis can help in choosing the type of harmonization most appropriate in a given context. This article analyzes the development of harmonization strategies in the European Community/European Union. The European experience shows that far-reaching economic integration can be achieved without suppressing cultural diversity and legitimate differences in national preferences.     

论司法实践中的痕迹鉴定和同一认定结论

痕迹鉴定是一种司法活动，经鉴定后得出的结论尤其是同一认定结论在司法实践中具有很大的价值，某些时候成为定案的主要或唯一证据。但在实践中，却曾发现本来只能给出种类认定等其它结论，却得出了同一认定结论；或者能够得出同一结论却只给出种类认定等其它结论。前者有可能误导法官，被法庭采信成为定案的证据之一，导致冤、假、错案：后者则淹没了同一认定结论在司法实践中应有的价值。只有掌握痕迹鉴定的规律，充分挖掘痕迹本身的信息，才能最大程度发挥同一认定结论的司法价值。

中外学位学历互认协议的法律性质、效能及发展趋势

在经济全球化和高等教育国际化的背景下,高等教育学历学位相互承认问题的重要性与日俱增。中外学位学历互认协议是中国与有关国家之间实现高等教育国际合作的重要途径,从本质上讲中外学历学位互认协议应该属于国际条约法的范畴,具有促进相关主体权益的保障、提供学位学历的法律保证、提高院校质量的可靠性、促进留学市场的规范性、增加中国教育的认可度、促进国际教育服务的自由化的法律效能。未来中外学位学历互认协议的发展趋势将集中在协议内容更加细化、互认方法更加多元、互认协议更关注实施效果、互认协议与国内法的衔接更加完善等方面。
