Silphids in urban forests: Diversity and function

Many ecologists have examined the process of how urbanization reduces biological diversity but rarely have its ecological consequences been assessed. We studied forest-dwelling burying beetles (Coleoptera: Silphidae)—a guild of insects that requires carrion to complete their life cycles—along an urban-rural gradient of land use in Maryland. Our objective was to determine how forest fragmentation associated with urbanization affects (1) beetle community diversity and structure and (2) the ecological function provided by these insects, that is, decomposition of vertebrate carcasses. Forest fragmentation strongly reduced burying beetle diversity and abundance, and did so far more pervasively than urbanization of the surrounding landscape. The likelihood that beetles interred experimental baits was a direct, positive function of burying beetle diversity. We conclude that loss of burying beetle diversity resulting from forest fragmentation could have important ecological consequences in urban forests.     

生物多样性保护与知识产权

生物多样性保护与知识产权存在较大的关联性,《生物多样性条约》的相关条款与知识产权密切相关,围绕生物资源保护与利用的知识产权理论不断发展,我国的相关法律制度也应加以完善。     

论互联网时代政治传播的个性化与多元化

政治传播的最终目的在于使受众成为完成党和政府的政治文化建构及政治行为实施的一部分。互联网作为新兴的大众传播媒介，它的兴起为政治传播提供了新的交流平台和多元化的言说空间。伴随着互联网成长起来的新生代以及这一代人所创造的新生代文化在客观上影响着当代政治的叙述方式，这种文化特征要求政治叙述具有个性化特征；同时，政治人物的个人形象在互联网时代的政治传播中也显示出前所未有的影响力。     

Origins and destinies: Immigration to the United States since World War II

Contemporary immigration to the United States and the formation of new ethnic groups are the complex and unintended social consequences of the expansion of the nation to its post-World War II position of global hegemony. Immigrant communities in the United States today are related to a history of American military, political, economic, and cultural involvement and intervention in the sending countries, especially in Asia and the Caribbean Basin, and to the linkages that are formed in the process that open a variety of legal and illegal migration pathways. The 19.8 million foreign-born persons counted in the 1990 U.S. census formed the largest immigrant population in the world, though in relative terms, only 7.9% of the U.S. population was foreign-born, a lower proportion than earlier in this century. Today's immigrants are extraordinarily diverse, a reflection of polar-opposite types of migrations embedded in very different historical and structural contexts. Also, unlike the expanding economy that absorbed earlier flows from Europe, since the 1970s new immigrants have entered an hourglass economy with reduced opportunities for social mobility, particularly among the less educated, and new waves of refugees have entered a welfare state with expanded opportunities for public assistance. This paper seeks to make sense of the new diversity. A typology of contemporary immigrants is presented, and their patterns of settlement, their distinctive social and economic characteristics compared to major native-born racial-ethnic groups, and their different modes of incorporation in—and consequences for—American society are considered.     

Fit and Skill in Employee Selection: Insights from a Study of Headhunters

We draw upon evidence from a qualitative study of headhunters to provide insights into the character and importance of candidate fit and skill for the selection of a broad range of white-collar employees. Headhunters suggest that the fit of a job candidate is assessed at two levels, one corresponding with a general compatibility with organization-level norms, culture, and strategy, the other corresponding more closely with traits and characteristics of the person or persons with whom the job candidate actually interviews. Skill—a factor which is largely neglected by those who tout the importance of fit—also plays an important and independent role in employee selection. Stalls that influence the selection of employees from a pool of candidates tend to be highly specific if not idiosyncratic, and take the form of what headhunters call hot buttons. We conclude by discussing the conceptualization, causes, and implications of fit; we also consider how the importance of fit and hot buttons challenges the explanatory logic of standard accounts of labor-market success.     

3-6岁幼儿责任感差异性研究

责任感是一个人主动施以积极有益作用的精神。研究采用实验法,通过前后测对120名3-6岁幼儿责任感进行测查,经分析对比发现：培养前和培养后,三个不同年龄阶段幼儿所表现出来的责任感都存在极其显著的差异,且男孩和女孩的责任感在不同程度上存在性别差异。     

语言多样性、信息获取与分析师盈余预测质量

考察了语言多样性对分析师盈余预测质量的影响,以及这种影响如何因员工教育水平的不同而变化.基于中国上市公司的实证检验结果显示,语言多样性显著降低了分析师盈余预测质量,但是随着公司员工受教育水平提高,语言多样性对分析师盈余预测质量的负面影响有所减弱.进一步研究发现,分析师与CEO间的校友关系增强了员工教育水平对语言多样性与分析师盈余预测准确性之间关系的正向调节作用.研究结论一定程度上丰富了分析师私有信息获取及其影响机理以及社会关系等方面的文献,而且还可帮助投资者、监管者等利益相关方更好地理解分析师行为,促进资源合理配置,增强资本市场的有效性等方面具有一定的启示意义.     

The effect of cognitive diversity on the illusion of control bias in strategic decisions: An experimental investigation

By integrating cognitive diversity into debiasing literature, this paper contributes towards opening the black box of executive judgment. Based on information processing theory we investigate the role of cognitive diversity in strategic decision making. We apply a vignette-based experimental research design to examine the effect of cognitive diversity in teams on decision maker's illusion of control. The results of these experiments provide evidence for a positive influence of high cognitive diversity for debiasing judgment while similarly indicating no such effect for groups with low cognitive diversity. These findings suggest that group composition aspects can play an important role for improving judgment in decision making teams and open promising new avenues for studying debiasing in behavioral strategy research.
