In this study we assess the sustainability of the Brazilian soy industry over the past 40 years in comparison to alternative land uses. We conclude that Brazilian soy production performs as well as or better than sugarcane or cattle production in a number of areas, including macroeconomic contributions, local economic development and land use efficiency, though it involves similar tradeoffs between growth and equity, and food production and conservation. While there is no evidence that soy has reduced food security in Brazil, tax redistributions and value-added activities from soy remain limited, particularly in comparison to sugarcane production. Emerging environmental governance measures have helped to reduce the land cover impacts from soy; however, little effort has been taken to minimize the impacts of intensification.  相似文献

Drawing on participatory action research with La Via Campesina’s US member groups, this paper traces the coloniality of US agricultural policy – and the uses of this analytic lens. The framework of coloniality conjures history, contextualizing US Department of Agriculture (USDA) racism within long legacies of subjugation, while paying homage to historical resistance. It raises the stakes regarding the neo-imperialism of agribusiness monopolies, while highlighting divide-and-conquer strategies and the colonialist mentalities that linger on despite reform. Assertions of coloniality, however, risk nostalgia for 18th century pastorals, or may jeopardize hard-fought-for relationships of trust with USDA personnel. Deployment demands self-reflexivity, on the part of academia, which like the USDA is neo-colonial, yet not monolithic. Most importantly however, the discursive impact of coloniality builds upon existing, grassroots articulations of the need to decolonize agricultural policy. Calling out the coloniality of US agricultural policy echoes global revalorizations of peasant agriculture, while overcoming the constraints of the term ‘peasant’ in US-English-speaking contexts. Accordingly, it could facilitate dialogue among grassroots agrarian alliances within the US and, internationally, with international advocacy for peasants’ rights.  相似文献

This paper links campaign resources and voter calculus through a microeconomic optimization framework. I assume that candidate policy positions are fixed while personal valence scores and the salience of issue dimensions are malleable. Low valence candidates with many proximate competitors in the policy space will focus on building valence. High valence candidates who are relatively ??unclustered?? in the policy space will focus on manipulating issue salience. Resources devoted to diminishing others?? valence scores will increase as the number of viable candidates decreases. The model??s results are tested, where feasible, using data from the Democratic Party primary of 2004.  相似文献

This essay attempts to explore trademark law and the marks themselves from a semiotic viewpoint to provide a deeper understanding to (trademark) law as a system of signs. Although the language of trademark law may suggest slightly different meanings, for the purpose of this essay “trademark” will refer to an area of law (unless otherwise indicated) and “mark” will refer to the individual sign. The first part of this essay will provide a brief overview of semiotics. Second, it will outline a general look at trademark law as set forth in the Lanham Act. The third section is a semiotic approach to provide a deeper understanding of trademark law. Finally, the essay will analyze a seminal trademark case whilst using semiotics to address legal meaning within the case. Semiotics teaches that no absolute meaning can be found. This essay, then, attempts to secure at least one particular meaning of the Qualitex case and what it means in trademark law today.  相似文献

Mixed logit (MXL) is a general discrete choice model thus farunexamined in the study of multicandidate and multiparty elections.Mixed logit assumes that the unobserved portions of utilityare a mixture of an IID extreme value term and another multivariatedistribution selected by the researcher. This general specificationallows MXL to avoid imposing the independence of irrelevantalternatives (IIA) property on the choice probabilities. Further,MXL is a flexible tool for examining heterogeneity in voterbehavior through random-coefficients specifications. MXL isa more general discrete choice model than multinomial probit(MNP) in several respects, and can be applied to a wider varietyof questions about voting behavior than MNP. An empirical exampleusing data from the 1987 British General Election demonstratesthe utility of MXL in the study of multicandidate and multipartyelections.  相似文献
