The Determinants of Trust and Credibility in Environmental Risk Communication: An Empirical Study

This study examines a key component of environmental risk communication; trust and credibility. The study was conducted in two parts. In the first part, six hypotheses regarding the perceptions and determinants of trust and credibility were tested against survey data. The hypotheses were supported by the data. The most important hypothesis was that perceptions of trust and credibility are dependent on three factors: perceptions of knowledge and expertise; perceptions of openness and honesty; and perceptions of concern and care. In the second part, models were constructed with perceptions of trust and credibility as the dependent variable. The goal was to examine the data for findings with direct policy implications. One such finding was that defying a negative stereotype is key to improving perceptions of trust and credibility.     

Culture, Cosmopolitanism, and Risk Management

Most cultural approaches to risk management deal with the connections between the forms of social relations within groups and the risk concerns of those groups. According to these theories, a certain limited set of different relational forms (usually three, four, or five) lead to specific, different and conflicting, risk concerns. In contrast to these theories, cosmopolitanism is an approach to culture that focuses, not on forms of sociality, but on changes among forms—expansions and contractions in the inclusivity of forms and movement by persons from one form of sociality to another. Relative to other cultural theories, cosmopolitanism thus is much more concerned with the solution of risk management problems than with their origins. Cosmopolitanism can be thought of as a cultural continuum, with cosmopolitanism at one end and pluralism at the other. Cosmopolitan persons are more open to cultural change—and thus the solution of risk management problems. In this article, we outline our new theory of cosmopolitanism, describe a method for measuring it and present an experimental study that tests some implications of the theory. Results from the study support the theory by showing that, compared to pluralistic respondents, cosmopolitan respondents are more inclusive in their risk management judgments—that is, they express equal concern for a local and a national issue, whereas the pluralistic respondents express greater concern in the local case. We discuss the risk management implications of a cosmopolitan approach to culture.     

Adaptive Build-up and Breakdown of Trust: An Agent Based Computational Approach

This article employs Agent-Based Computational Economics (ACE) to investigate whether, and under what conditions, trust is viable in markets. The emergence and breakdown of trust is modeled in a context of multiple buyers and suppliers. Agents develop trust in a partner as a function of observed loyalty. They select partners on the basis of their trust in the partner and potential profit, with adaptive weights. On the basis of realized profits, they adapt the weight they attach to trust relative to profitability, and their own trustworthiness, modeled as a threshold of defection. Trust and loyalty turn out to be viable under fairly general conditions.

Consumer trust in B2C e-Commerce and the importance of social presence: experiments in e-Products and e-Services

Reducing social uncertainty—understanding, predicting, and controlling the behavior of other people—is a central motivating force of human behavior. When rules and customs are not sufficient, people rely on trust and familiarity as primary mechanisms to reduce social uncertainty. The relative paucity of regulations and customs on the Internet makes consumer familiarity and trust especially important in the case of e-Commerce. Yet the lack of an interpersonal exchange and the one-time nature of the typical business transaction on the Internet make this kind of consumer trust unique, because trust relates to other people and is nourished through interactions with them.This study validates a four-dimensional scale of trust in the context of e-Products and revalidates it in the context of e-Services. The study then shows the influence of social presence on these dimensions of this trust, especially benevolence, and its ultimate contribution to online purchase intentions.

安徽省学前教育资源地区间配置差异分析

笔者采用锡尔指数及其一阶模型,对安徽省学前教育中的经费投入、师资力量、办学规模等教育资源配置的差异进行了测度,并将教育资源配置的差异性分解为皖北、皖中、皖南三个地域间的差异以及三个地域内各地区之间的差异。研究发现：三个地域内各地区差异是造成全省学前教育资源配置差异的主要原因;学前教育经费投入、师资力量和办学规模都存在着不同程度的配置差异,其中财政性教育公用费各地区差异最明显,专任教师的缺乏造成了各地区师资力量资源配置的差异;办学规模已基本能满足全省幼儿入园的需要,但结构性矛盾仍然突出。     

股权众筹是否真的那么美--基于美国制度缺陷的再思考

股权众筹作为初创企业采用的一种利用互联网向大众募集小额资本的融资方式，以“脱媒式”对接投融资双方的优势，利用互联网的人群聚集与信息广泛传播效应，降低投融资方之间沟通成本，有助于投融资意向的快速达成。2012年美国JOBS法案的高调出台，吸引了全球范围内的广泛关注。但股权众筹制度在美国已受到诸多批判，除信息披露要求弱化引发的欺诈风险增加外，在注重前端融资效率的同时却忽略了投资端的设计和保护，尤其是众筹股权的流通和退出问题等。美国立法与实践领域对于这些问题尚未取得彻底的突破。股权众筹以美国模式为样板引入中国，在遭遇中国固有法律体系及制度的困扰后，中国股权众筹实践陷入更多困境。通过对美国相关制度出台的背景及存在的不足进行分析，对照中国实践，锁定实践中产生的新问题，并深入探讨现有解决路径能否真正缓解这些不足，以期对股权众筹制度重新进行明确的定位。     

Trust and health in Eastern Europe: Conceptions of a new society

Little attention has been paid to why trends and levels of mortality and morbidity differ in Eastern Europe and few studies have addressed people's own perceptions of their new political system – perceptions which per se may be important for social development. The aim of the present study was to analyse the extent to which trust and economic circumstances affect self‐rated health in Poland, Estonia and Russia and how much health differences between the countries can be explained by these factors. A better economy and higher trust were related to better individual health, while economic factors seemed most important for inter‐country differences. It is probable that both institutional factors and individual perceptions contribute to people's well‐being, but in terms of social policy, an improved welfare system may be the most effective way forward.
