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.

Exit from the high street: an exploratory study of sustainable fashion consumption pioneers

In today's fashion system, dominated by business models predicated on continual consumption and globalized production systems that have major environmental and social impacts, the consumption of ‘sustainable fashion’ takes on an almost paradoxical quality. This paper explores this paradox by focusing on a previously under‐researched group of consumers – ‘sustainable fashion consumption pioneers’ who actively engage and shape their own discourse around the notion of sustainable fashion consumption. These pioneers actively create and communicate strategies for sustainable fashion behaviour that can overcome the nebulous and somewhat paradoxical reality that sustainable development in the fashion industry presents. Specifically, we use passive netnography and semi‐structured interviews to illuminate the role of motivational and contextual factors that help shape these consumers' definitions of sustainable fashion including such key behaviours as purchasing fewer garments of higher quality, exiting the retail market, purchasing only second‐hand fashion goods and sewing or upgrading their own clothing. Central to much of these behaviours is the notion that personal style, rather than fashion, can bridge the potential disconnect between sustainability and fashion while also facilitating a sense of well‐being not found in traditional fashion consumption. As such, our research suggests that for these consumers sustainability is as much about reducing measurable environmental or social impacts as it is about incorporating broader concepts through which to achieve goals beyond the pro‐environmental or ethical.     

论建立耕地保护的土地管理新机制

研究目的:探讨国土资源参与宏观调控情况下,如何建立一种低成本、高效率、信息准确、资料更新及时的土地管理新机制。研究方法:实证法,比较研究法,逻辑分析法。研究结果:为保护和合理利用有限的土地资源,应该将土地管理工作重点转移到城市(镇)规划管理区,建立一套以城市(镇)规划管理区为重点的耕地保护工作机制。在这种新工作机制下,几项重大土地管理工作,如新一轮土地利用大调查、土地统计制度、建设用地审批制度等,在工作思路和工作方法方面需要作出相应的调整。     

Public transport and car-sharing—benefits and effects of combined services

The article presents the results of a German research project, where recommendations for the synthesis of public transport and car-sharing/car clubs are given. In order to determine effects and factors of success of combined services, the adoption process, the mobility behaviour and customer satisfaction were investigated within the context of model projects in two German cities. The results prove that car-sharing is suitable as a supplement to public transport.

The distinction between commercial and non-commercial bus services in Germany: Given by nature?

German public transport services by bus are characterized by a regulatory framework that distinguishes between commercial and non-commercial services. Contrary to the apparent views of legislators, this paper shows that costs and revenues are not the only parameters determining whether or not operators are able to provide services in a commercially viable way.Apart from the local characteristics of the specific service, we show that the classification of services as commercial versus non-commercial is determined in large part by the public transport authorities that set minimum quality standards to be provided by operators. Our analysis shows that the authorities awarding the contracts in some cases affect market organization significantly depending on how they make use of this power. Furthermore, market organization differs substantially with respect to the awarding structure and the contractual relationships, thus creating a challenge for operators and authorities in an embryonic market.
