论遗失物之立法现状及其制度构建

最新审议通过之《物权法》虽肯定了悬赏寻找遗失物的合法性与合理性,但仍旧未赋予拾得人报酬请求权与附条件先占取得权,并仍规定无人认领的遗失物归国家所有,此举违背民法的市民法与权利法的本质以及权利义务均衡原则,有必要加以修正和完善。

Topic variability and criteria in interpretational history teaching

This paper studies the teacher perceived applicability of historical topics for interpretational history teaching and the criteria teachers use to evaluate this applicability. For this study, 15 expert history teachers in the Netherlands striving for interpretational history teaching were purposefully selected. Teachers were asked to mention historical topics using a ranking task technique to rank topics in order of applicability and to elaborate on how the topics were ranked. The results showed a large variation in perceived applicability among topics, both within and between teachers. Eight different topic-applicability criteria were discerned in the teachers’ elaborations: (1) topic knowledge; (2) topic affinity; (3) topic constructedness; (4) topic deconstructability; (5) topic abstractedness; (6) topic sensitivity; (7) topic materials; and (8) topic inclusion in the history curriculum. We found that teachers tended to judge topics as applicable for interpretational history teaching partly depending on the degree of ‘canonised interpretativity’ in lesson materials and the curriculum, and to the degree to which they belonged to ‘cold’ (morally neutral) or ‘hot’ (morally sensitive) history. A theoretical implication of the findings is that interpretational history teaching is topic-dependent. Teachers can be supported to teach history as interpretation by structured pedagogies.

内外结合觅选题 打开编辑学论文写作通道

撰写编辑学论文,是科技期刊青年编辑业务能力提升和个人发展的需要,也是加速个人成长的有效途径。确定选题是撰写论文的必要条件,在凸显编辑主体主观能动性的基础上,从内在和外在因素2个维度对如何发现选题进行探讨,帮助青年编辑尽快打开论文写作通道。其中:内在因素包括困惑破解、经验积累、自我学习、情怀表达等,这是开展研究的“源头活水”,青年编辑据此可以较容易地觅到选题;外在因素则包括新闻热点关注、与同行交流、向前辈学习等,借助这些“他山之石”,青年编辑可拓宽选题思路,对感兴趣的编辑学研究专题进行深耕细作。     

Real time search on the web: Queries,topics, and economic value

Real time search is an increasingly important area of information seeking on the Web. In this research, we analyze 1,005,296 user interactions with a real time search engine over a 190 day period. Using query log analysis, we investigate searching behavior, categorize search topics, and measure the economic value of this real time search stream. We examine aggregate usage of the search engine, including number of users, queries, and terms. We then classify queries into subject categories using the Google Directory topical hierarchy. We next estimate the economic value of the real time search traffic using the Google AdWords keyword advertising platform. Results shows that 30% of the queries were unique (used only once in the entire dataset), which is low compared to traditional Web searching. Also, 60% of the search traffic comes from the search engine’s application program interface, indicating that real time search is heavily leveraged by other applications. There are many repeated queries over time via these application program interfaces, perhaps indicating both long term interest in a topic and the polling nature of real time queries. Concerning search topics, the most used terms dealt with technology, entertainment, and politics, reflecting both the temporal nature of the queries and, perhaps, an early adopter user-based. However, 36% of the queries indicate some geographical affinity, pointing to a location-based aspect to real time search. In terms of economic value, we calculate this real time search stream to be worth approximately US $33,000,000 (US $33 M) on the online advertising market at the time of the study. We discuss the implications for search engines and content providers as real time content increasingly enters the main stream as an information source.
