Because national governments have limited power to regulate the conditions of production abroad, voluntary certification schemes have come to play a significant role in transnational regulation of many global supply chains, particularly in the food sector, where multiple regulatory issues are in play and different certification schemes compete. However, we still know relatively little about the political-economic factors that shape the construction of certified citrus markets for these competing standards. Based on an original dataset from a comparative survey of US and Dutch importers, this paper investigates factors that shape the construction of certification markets for citrus, focusing on the construction of markets for different kinds of certification schemes including Fair Trade, Organic, and GlobalGAP certification. The paper investigates from a comparative perspective whether the construction of markets differs across the US and Dutch political economies. The results show both the enduring effects of national political economies and the importance of global value chain dynamics. Across competing schemes, the industry-sponsored business-to-business certification systems have outcompeted consumer-facing label systems.  相似文献

Our purpose is to estimate a model of non-industrial forest landowner behavior that considers certain types of behavior that have escaped discussion and rigorous investigation in the literature, yet which are critical to future policy making. Our focus on the many different but related decisions landowners make broadens the typical understanding of landowner behavior to show how bequest motives, debt and participation in non-timber activities, and harvesting decisions are interrelated and dependent on landowner preferences, market, and land characteristics.  相似文献

A person's image incorporates three principal elements: how you look, sound and present yourself. Alterations in the world of work have increased the importance of image in the work place and have created a demand for a new form of recipe knowledge – impression management. This has encouraged the formation of specialist image consultancy companies, as well as the development of new techniques of image construction and management. This article provides an analysis of the image consultancy industry in the United Kingdom. It explores the geography of the industry, motivations for establishing an image consultancy firm, the networks consultants develop and the methods of client acquisition. The results of a postal survey of image consultants are reported.  相似文献

This paper explores the relationship between relevant senate committee membership and campaign contributions from financial services industry political action committees (PACs) from 1998 to 2002. Since this was a period of significant legislative activity affecting the industry, it provides a fruitful time period to investigate the relationship between contributions and committee membership. It is found that membership on the Senate Banking Committee is consistently related to contributions from financial services PACs. Membership on the Senate Finance Committee is related to PAC contributions from some sectors of the industry for some time periods. It is also found that contributions are significantly higher for those senators facing re-election in the particular election cycle. The importance of relevant committee membershipto PAC contributions in the senate is consistent with previous work dealing with the House.  相似文献

The present study was carried out in the Ile-de-France region surrounding Paris, which is both the biggest conurbation in France and a large agricultural area. In areas such as these, airborne pollutants from road traffic may adversely affect the quality of the food produced by farms close by. This raises questions about the spatial compatibility of farming and road networks, although there is currently no scientific consensus concerning potential health risks for producers and consumers. Some actors in agricultural supply chains have tried to limit potential risks by producing technical guidelines, including isolation distances between major roads and fields farmed under contract. This paper analyses these “isolation distances”, using approaches from the agricultural and social sciences: surveys on stakeholders in agribusiness and on farmers, and a cartographic simulation submitted to the surveyed farmers for discussion. The results show that isolation distances serve to create market opportunities in a context of market segmentation, or are applied as a precautionary principle. Though not a widespread practice, safety distances could have considerable impacts on farms in terms of both technical management and total farm area, thus calling for further scientific research on this issue.  相似文献
