This article reviews proposals regarding the recent food crisis in the context of a broader, threshold debate on the future of agriculture and food security. While the MDGs have focused on eradicating extreme poverty and hunger, the food crisis pushed the hungry over the one billion mark. There is thus a renewed focus on agricultural development, which pivots on the salience of industrial agriculture (as a supply source) in addressing food security. The World Bank's new 'agriculture for development' initiative seeks to improve small-farmer productivity with new inputs, and their incorporation into global markets via value-chains originating in industrial agriculture. An alternative claim, originating in 'food sovereignty' politics, demanding small-farmer rights to develop bio-regionally specific agro-ecological methods and provision for local, rather than global, markets, resonates in the IAASTD report, which implies agribusiness as usual 'is no longer an option'. The basic divide is over whether agriculture is a servant of economic growth, or should be developed as a foundational source of social and ecological sustainability. We review and compare these different paradigmatic approaches to food security, and their political and ecological implications.  相似文献

The Lisbon Treaty has led to an expansion of the rights of parliaments in scrutinizing EU decision making, including—for the first time—also regional parliaments. Yet, theoretically informed empirical work on how regional legislatures adapt to the increasing relevance of the EU for subnational jurisdictions remains scarce. Drawing on data from an original survey of 251 MPs, conducted in seven German Länder in 2011, we explore regional MPs' involvement in EU affairs. We find strong variation among MPs' level of EU involvement. Exploring different sets of explanations, we show that individual-level factors—the perceived salience of the EU and MPs' perceived influence in EU matters—hold the highest explanatory power.  相似文献

As a result of changes in the campaign landscape, candidates have several strategic options available to them, particularly when considering how to respond to voters’ gender stereotypes. The goal of this paper is to understand candidates’ use of strategies based on gender stereotypes by emphasizing either particular issues or particular traits that are commonly associated with one gender or the other. To do this, I developed hypotheses of why candidates might choose a trait or issues strategy based on gender stereotypes. I tested these hypotheses using a large-scale content analysis of candidate websites over four election cycles. I found that female candidates mostly pursued strategies that were consistent with gender stereotypes. Interestingly, female candidates were found to have different strategies on different pages of their websites. I discuss the implications of gender-based strategies for the election of female candidates and for representation.  相似文献

Multidetector computed tomography is becoming more widespread in forensic medicine. In most services, autopsy assistants perform the radiological examination. We introduced professional radiographers into the legal medicine service and hypothesized they would also be able to take over duties currently reserved for other specialists. The aims of this study were to evaluate if radiographers could be trained as "forensic radiographers" by (1) integrating graduated medical radiographers into the legal medicine service, (2) investigating the advantages of this collaboration, and (3) defining the duties of the forensic radiographers.The study was performed prospectively on a group of 8 recruited radiographers who underwent a testing period with special training. They learned the basics of medicolegal case treatment, the autonomous execution of postmortem computed tomography angiography, and postprocessing of data. Seven of 8 radiographers finished the training and were integrated into our service. Although all radiographers were able to fulfill the duties demanded after the training period, some radiographers could not enter or complete the program because they were unable to work with dead bodies.Our study presents the advantages of integrating radiographers into the medicolegal team and proposes how to train the forensic radiographers. In addition, the duties and responsibilities of these new specialists are defined.  相似文献
