国际合作论文在大学排名体系中的影响

国际化水平是考察大学是否走向世界一流的重要指针,而国际合作论文是科研国际合作的重要载体,且在世界主要大学排名体系中占有重要权重。运用多元线性回归和因子分析方法分析US News、QS世界大学排名体系的数据,结果表明：国际合作论文数对大学声誉及排名、学科声誉及排名均有显著影响,并且往往作为一个单独因素影响排名的位次;国际合作论文比例对大学声誉及排名、学科声誉及排名的影响则较复杂,即对学科声誉及排名的影响较明显,但对大学声誉及排名的影响较小,有时甚至不明显;国际化在本质上反映的是教学能力和水平,国际化水平最终要体现在教学水平上,教学指标具有与科研产出一样的影响方式。因此,在一流大学建设过程中,国际合作论文和教学均要得到高度重视。     

中国现代诗歌美学的奇峰——论艾青的《诗论》

艾青的诗论以形象精到的语言描述了＂真、善、美＂相统一的美学观作为诗歌的出发点和落脚点,提出了以真善美相统一为核心的＂人民即诗神＂的诗歌创作与诗歌评伦的美学主张,系统地以文艺美学来论述诗歌创作过程与诗美的特质,科学地揭示了诗歌作为艺术的本质特征。艾青诗论在中国现代诗歌美学研究中占有崇高地位。     

基于“柠檬”理论的在线信誉反馈系统有效性研究

信任问题是困扰在线拍卖市场发展的瓶颈之一.在线信誉反馈系统在消除信息不对称性,解决在线拍卖市场逆向选择问题中发挥着重要的作用.首先分析在线拍卖市场中逆向选择问题产生的原因,而后基于"柠檬"理论,从更换交易对手的重复博弈角度分析在线信誉反馈系统中信誉运行模型,对在线拍卖市场的信誉运行机理进行分析.研究指出在线信誉反馈系统能激励卖家诚信交易,一定程度上降低逆向选择问题,为我国在线拍卖网站和网络卖家更好地实施网络声誉战略提供一个思路.     

“艾滋女”事件的侵权法分析

＂艾滋女＂事件是一起典型的侵犯人格权的案件,其中,最核心的问题是侵犯隐私权和名誉权。美国侵权法重述对隐私权进行了四分,但这并不完全适用于我国。在该案中,杨某侵犯了闫德利的姓名权、肖像权、隐私权和名誉权,并且同时侵害了279个＂嫖客＂的隐私权和名誉权,行为人需要对此承担民事责任。在个人公布自己隐私的情况下,隐私处分也有一定的界限,即需要受到公序良俗和法律的限制;在共同隐私的情况下,行使自己的隐私处分权不得侵害共同隐私权人中其他人的权利。     

考虑广告主信誉和用户体验的GSP机制研究

目前,竞标在线广告位是广大广告主宣传其产品的重要途径之一,在线广告位的拍卖已成为搜索引擎企业最主要的盈利手段之一。在国内,广告位拍卖机制的逐利本质诱发了大量的虚假广告,引发了公众的广泛争议;拥有高报价的广告主并不总是带给搜索引擎用户好的用户体验,这些问题已成为搜索引擎亟需解决的重要问题。本文提出了一种既考虑广告主信誉又考虑用户体验的可信有效竞价广告位拍卖机制,定义了在该机制下的对称纳什均衡,给出了广告主的均衡竞价策略,证明了在该均衡下的配置是有效率的。通过与单纯竞价GSP拍卖机制进行比较,我们发现用户的满意度得到了提高,这增加了搜索引擎的竞争优势。此外,本文的拍卖机制不仅有利于促进广告主提高信誉,在提高搜索引擎的长期均衡收益和拍卖效率方面也有一定的优势。通过数值模拟验证了我们的结论。     

Cosine similarity-based clustering and dynamic reputation trust aware key generation scheme for trusted communication on social networking

Social networking sites (SNSs) make it possible to connect people and they can communicate with others. Due to the lack of privacy mechanisms, the users in SNSs are vulnerable to some kinds of attacks. Security and privacy issues have become critically important with the fast expansion of SNSs. Most network applications such as pervasive computing, grid computing and P2P networks can be viewed as multi-agent systems which are open, anonymous and dynamic in nature. Moreover, most of the existing reputation trust models (RTMs) do not depend on any clustering structures. The clustering structures are used to effectively calculate the trustworthiness of the network nodes. In this paper, a novel cosine similarity-based clustering and dynamic reputation trust aware key generation (CSBC-DRT) scheme is proposed. For better faced clustering, a cosine similarity measure is estimated for all the nodes on the network. Based on the similarity measure among the nodes, the network nodes are clustered into disjoint groups. The RTM is built in this proposed scheme. Here, an improved MD5 algorithm is explored for key generation and key verification. After the key verification, the trusted measures such as reputation value, positive edge and negative edge values are computed to formulate the trusted network. The proposed scheme performs better than the existing RTM, which provides trusted communication in social networks.     

Effects of issue ownership and issue obtrusiveness on corporate reputation at two Korean corporations

This study attempts to identify the effects of issue ownership of a corporation on its reputation, and the moderating effect of issue obtrusiveness. Two representative Korean corporations (Hyundai and SK) were selected and their reputations were measured. It was shown that a corporation, which owns issues that were perceived as important by publics, has a higher corporate reputation. There was no moderating effect of issue obtrusiveness on the relationship between issue ownership and corporate reputation; however, there was a possibility of issue obtrusiveness as an independent variable. Implication for public relations research and practice was discussed.     

券商声誉、制度环境与 IPO 公司盈余管理

基于成熟资本市场的研究表明,高声誉券商会抑制 IPO 公司的盈余管理． 本文以 2001 － 2011 年处于中国制度环境下的 IPO 公司为样本,重新考察了券商声誉与 IPO 公司盈余管理之间的关系． 研究发现,券商声誉越高,其所承销 IPO 公司的盈余管理程度也就越高,但券商声誉与 IPO 公司盈余管理程度之间的正向关系只有在投资者法律保护较差的地区才显著． 进一步的研究还发现,高声誉券商纵容或协助 IPO 公司盈余管理的重要动因在于获取更高的经济收益． 尽管高声誉券商确实能够降低 IPO 公司的抑价率,但这是通过提高 IPO 公司盈余管理程度的途径来实现的． 本文的结论表明,要使我国资本市场中的券商声誉机制发挥作用,还需要大力提高券商机会主义行为所面临的法律风险．     

舆论监督中的公务员名誉权保护与限制——兼论公务员名誉新闻侵权责任的认定

舆论监督权的行使与公务员名誉权的保护由于价值取向不同经常发生冲突,其协调关键在于以公共利益为标准来界定权利的边界,在新闻侵权责任的认定上确立实际恶意、大体真实、适度容忍三原则。     

No praise without effort: experimental evidence on how rewards affect Wikipedia's contributor community

The successful provision of public goods through mass volunteering over the Internet poses a puzzle to classic social science theories of human cooperation. A solution suggested by recent studies proposes that informal rewards (e.g. a thumbs-up, a badge, an editing award, etc.) can motivate participants by raising their status in the community, which acts as a select incentive to continue contributing. Indeed, a recent study of Wikipedia found that receiving a reward had a large positive effect on the subsequent contribution levels of highly-active contributors. While these findings are suggestive, they only pertained to already highly-active contributors. Can informal rewards also serve as a mechanism to increase participation among less-active contributors by initiating a virtuous cycle of work and reward? We conduct a field experiment on the online encyclopedia Wikipedia in which we bestowed rewards to randomly selected editors of varying productivity levels. Analysis of post-treatment activity shows that despite greater room for less-active contributors to increase their productive efforts, rewards yielded increases in work only among already highly-productive editors. On the other hand, rewards were associated with lower retention of less-active contributors. These findings suggest that the incentive structure in peer production is broadly meritocratic, as highly-active contributors accumulate the most rewards. However, this may also contribute to the divide between the stable core of highly-prodigious producers and a peripheral population of less-active contributors with shorter volunteer tenures.
