More and more consumers are willing to pay a premium for fair trade products. However, great potential remains as the market shares of these products are still low. In the present study, neutralization theory was applied to investigate the reasons for consumers hesitating to buy more fair trade products. A postal paper‐and‐pencil survey was sent out using random addresses from the telephone book in the German‐speaking part of Switzerland, resulting in a final sample size of n = 620. The results show that the techniques of neutralization are used to various degrees. A principal component analysis resulted in two strategies of neutralization: an internal strategy (focusing on the consumers themselves) and an external strategy (focusing on the farmers in developing countries). A regression analysis proved that the internal neutralization strategy was an important predictor for fair trade buying behaviour, even when controlling for attitudes towards fair trade.  相似文献

Stakeholder involvement in research processes is widely seen as essential to enhance the applicability of research. A common conclusion in the extensive body of literature on participatory and transdisciplinary research is the importance of the institutional context for understanding the dynamics and effectiveness of participatory projects. The role of institutional context has become increasingly important in view of large international research projects implementing shared participatory methodologies across countries (for example within Horizon 2020 and within CGIAR programmes), which each have different institutional contexts. Despite the generally accepted importance of the institutional context for understanding the unfolding of participatory and transdisciplinary research projects, surprisingly little research has actually looked into its role in greater detail. This paper aims to fill this gap in the literature by studying how a set of participatory principles and methods in a European project on integrated pest management (denoted as co-innovation in the project under study) was applied by researchers and advisers operating in a single international research project under the institutional conditions of four countries. The principal finding of this study is that, although constraints and enablers of participatory research at the personal level (e.g. researcher identity) were similar across the studied countries, research organisation- and community-based constraints and enablers differed, as well as those at the level of the overall innovation system. The institutions at different levels interact and create country-specific histories and path-dependencies, which lead to different degrees of propensity and preparedness, and hence different starting positions for participatory approaches. Consequently, when participatory research methods and approaches are applied in different contexts following a one-size-fits-all approach they may be less effective if not translated to institutional conditions at different levels. The study suggests that large international participatory research projects make provision in their design for careful selection of project team individuals, the composition of teams, and pay attention to the room for manoeuvre that the project, institute and national contexts provide for participatory research. To support the adjustment of participatory approaches to local institutional conditions, large international projects would benefit from fostering learning spaces that enable reflection on translation to local contexts and are capable of connecting to a wider network of decision makers and influencers that can facilitate institutional change in organisations and innovation systems.  相似文献

Open source software (OSS) projects represent a new paradigm of software creation and development based on hundreds or even thousands of developers and users organised in the form of a virtual community. The success of an OSS project is closely linked to the successful organisation and development of the virtual community of support group. This paper reviews different fields and research topics related to the OSS communities such as collective intelligence, the structure of OSS communities, their success, communities as virtual organisations, motivation, shared knowledge, innovation and learning. The main challenges, results obtained, and the knowledge areas are detailed for each topic.  相似文献

Social equality has emerged as one of the important ideals of human society, especially for development. Moreover, education has featured prominently among the many key drivers of equality. However, in developing nations like Ghana, education represents one of the areas in which gross inequality has eroded the country’s potential for attaining equality and development. The aim of the current study was to explore adolescents’ self-perceived barriers regarding access to quality education in the Northern Region of Ghana and provide suggestions on the way forward. A sample of 18 school-going adolescents from six secondary schools within the Northern Region of Ghana was purposively selected to participate in face-to-face interviews. The barriers identified included limited resources, gender disparities and a multi-dimension nature of poverty. Implications for policy and research are discussed.  相似文献

This paper identifies sustainable initiatives reported by “sustainability-champion” hotels in the Dominican Republic, while contrasting them against the views of key stakeholders. We adapt and apply Hart and Milstein's Sustainable Value Framework, and complement it with a Critical Management Studies approach. Our analysis relies on a mixed-methods approach (non-hierarchical k-means cluster analysis, as well as thematic and content analysis). Findings indicate that most hotels are engaging more actively in present-oriented strategies such as pollution prevention (especially, the international hotels) and in product/service stewardship. However, in the future-oriented strategies, hotels owned by local investors show higher commitment to both clean technology and innovation, and to the sustainability vision (as the firm's growth path). In addition, although the views of multiple stakeholders show a clear acknowledgment of the hospitality industry's sustainability efforts (particularly regarding education and environmental protection), they also offer differing views about the ultimate impact and value of those efforts for them and for the broader society. Our study offers a new theoretical lens to explore multi-stakeholder approaches and offers practical implications for the Dominican Republic's National Strategy for Development 2010–2030, as well as implications that may be of use for other tourism-dependent countries.  相似文献
