Peers Versus National Culture: An Analysis of Antecedents to Ethical Decision-making

Given the recent ethics scandals in the United States, there has been a renewed focus on understanding the antecedents to ethical decision-making in the research literature. Since ethical norms and standards of behavior are not universally consistent, an individual’s choice of referent may exert a large influence on his/her ethical decision-making. This study used a social identity theory lens to empirically examine the relative influence of the macro- and micro-level variables of national culture and peers on an individual’s intention to behave ethically. Our sample consisted of respondents from Germany, Italy, and Japan. The results indicated that both national culture and peers were found to act as significant referents in ethical decision-making dilemmas. Although peers exerted a much stronger influence on an individual’s ethical decision-making, the impact of peers varied depending on the national culture levels of individualism and power distance.

A body without a voice: A literary approach to Linguet's opposition to the physiocrats over the free trade in grain

Abstract

Linguet was a critic of the physiocrats and of what he perceived as the disastrous consequences the liberalisation of the trade in grain on the people. Linguet's rhetorical use of the voice of the people is studied here through its rhetorical device and its fantasmatic and ideological echoes. With his dramatised and polyphonic style Linguet quotes many different protagonists, but he chooses to neuter the people's voice on the rare occasions when it is heard. Despite this rather conventional suppression of the people's voice, Linguet's claims to be a spokesman or advocate of the people are quite convincing. Through his detailed and hyperbolic depiction of the physical suffering of starving people, Linguet shines a light on one of the blind spots of the Physiocratic doctrine which sees no damage in economic prosperity.     

重庆旧城改造区土地覆被与景观格局变化——以北碚区为例

以重庆市北碚区为例,以2001、2006和2011年三个时期的土地利用变更调查数据库数据为基础数据,借助GIS技术,对旧城改造区的土地利用/覆被与景观格局进行分析,结果表明:2001—2011年的10年期间,区域始终以农用地为主要覆盖类型,一级农用地变化幅度不大,农用地下的二级地类发生较大转变,其他农用地向林地及园地发生大幅转化,主要原因是北碚规划建设生态型新城区;建设用地不断增加,到2011年达到区域18.03%占有量,建设用地主要由未利用地转化而来;2001—2011年,区域景观破碎度呈现由小破碎度到大破碎度再到小破碎度的趋势,到2011年破碎度达到最小值;区域各地类的分维数呈现增加趋势,说明自然景观受人为因素的影响越来越大。

国际股票市场收益率和波动率的长记忆性研究

股票市场长记忆性问题是金融学研究的一个热点问题,对于市场有效性的研究和系统非线性结构的分析有着重要的意义。本文运用修正R/S分析和V/S分析两种方法对世界上28个国家(地区)的股票指数的日、周收益序列和日、周收益波动序列进行了完整的长记忆性研究。结果表明:对于收益序列,以美国为代表的大多数发达国家股市一般不存在长记忆性,而中国等发展中国家大多存在显著的长记忆性,尤其中国股市的长记忆性最强;对于收益波动序列,所有国家(地区)都具有长记忆性,并强于收益序列。
