The political geography of the global soybean complex is shifting. While the complex has long been controlled by US-based transnational corporations, new agribusiness actors, business logics and power relations rooted in South America and East Asia are emerging, based in part on commodity flexing. We explore how soybean flexing is shaping and being shaped by global restructuring of the soybean processing industry. Using the divergent histories and uses of soy in China and Brazil, we propose that in order to understand the changing soy landscape, we must examine the relationships between soy's multiple-ness and flexible-ness, the political economy of soy processing, and the relationships between crop ‘flexors’ – those powerful firms that control the soy complex – with each other and with governments. We demonstrate that the agribusiness actors who are gaining more control over the soy complex are doing so in part through flexing, and that the ability to flex may ultimately determine the trajectory of global agroindustrial restructuring. Finally, we raise questions and make suggestions for further research on flex crops. 相似文献

What can representations of women's ‘caring consumption’ (Thompson 1996) reveal about broad cultural understandings of the nature of motherhood? We study Canadian television advertisements to gain insight into the production of cultural schemas and the reproduction of beliefs about gender and motherhood. Employing an inductive qualitative analysis of portrayals of mothers and women who are not depicted as mothers, we find that the defining feature of mothers' consumption is a unidimensional depiction of control and caring for others, presented as self-evidently gratifying and fulfilling, in the absence of competing consumption goals. Mothers' identity emerges solely from successful consumer choices that benefit others. Such unidimensional representations of consumption stand in contrast to the consumption of women who are not depicted as mothers, who are found to engage in hyperbolic and indulgent consumption targeted towards self-gratification. We thus provide novel empirical data which show that depictions of consumption in mothers and in women not depicted as mothers are extreme in nature. Our findings provide support for, and elaborate on, the concept of ‘caring consumption’ by helping to make sense of media representations appearing within the conjunction of the contemporary marketing context of hyperconsumption, and the parenting/gender context of intensive mothering. By examining extreme consumption in television advertisements, we gain insight into features of maternal consumption ideals that may not be observable in everyday instantiations, such as the lack of mothers' consumption for self-benefit. 相似文献

This research seeks to understand which essential characteristics are necessary to drive municipal governments to adopt smart growth measures. By testing previously expected outcomes for why a local government would adopt a particular policy, we find an inherent need to create strong needs-based policies promoted by interest groups. We conducted a principal component analysis and a linear regression model to test several hypotheses. A discussion of this analysis is provided along with policy recommendations to explain why and when metropolitan areas use sustainability plans and how to encourage more to do so. 相似文献

The introduction of the Global Terrorism Database (GTD) nearly a decade ago sparked a revolution in terrorism studies. However, one major flaw in the database continues to plague GTD users. Data lost prior to digitalization, along with unsuccessful data recollection efforts, have left GTD without data on events that took place during the year 1993. The missing data prevents researchers from using the entirety of GTD's annual range (1970–2014) to conduct reliable time-series analyses. Additionally, it has likely contributed to the formation of theories and claims on faulty empirical ground. To remedy the problem, we have collected data on 4,206 unique terror-attack incidents, with the aim of documenting the universe of 1993 terrorism events. This article showcases our 1993 dataset and illustrates the importance of terrorism events in 1993 for the development of conflicts in Israel, Afghanistan, Colombia, and India. 相似文献

The fossil fuel divestment movement has been described as the fastest‐growing disinvestment movement in history, and in recent years it has continued to expand. Despite its growth, however, the movement has made little use of legal action, instead utilizing tactics of public pressure and persuasion, and the future role of litigation in the movement is unclear. To consider litigation's potential role in the movement and the challenges it may face, I examine the first and only case of litigation in the fossil fuel divestment movement thus far: Harvard Climate Justice Coalition et al. v President and Fellows of Harvard College et al. (2015), in which seven Harvard students (including the author) filed suit to compel the university to divest its endowment from fossil fuel companies. I examine motivations for filing the suit in the context of the broader fossil fuel divestment movement, the case's history, and the challenges faced by the suit, including arguments surrounding causation, particularization, representation of future generations, limiting principles, and framing. I then discuss potential opportunities for fossil fuel divestment litigation in the future. As the field of climate change law develops further, litigation over fossil fuel investments could grow in frequency and importance. 相似文献

We examine the academe–industry wage gap. Once self-selection and different personal characteristics of academic and industrial scientists have been taken into account the wage gap narrows from 28 to 13 %. The counterfactual wage faced by an academic scientist increases with time spent on development and decreases with time spent on research. This finding challenges the idea of a solely negative relationship between science and wages. We further find that preferences for science augment the relationship between research orientation and wages. Overall, the results have implications for policy makers that aim to increase development oriented research activities at universities, individual scientists thinking about whether to pursue a career in industry or academe, and managers trying to hire academic scientists. 相似文献
