This article draws upon existing literature to document and describe the rise of finance in food provisioning. It queries the role of financialization in the contemporary food crisis and analyzes its impacts upon the distribution of power and wealth within and along the generalized agro-food supply chain. A systematic treatment of key nodes in the supply chain reveals four key insights: (1) the line between finance and food provisioning has become increasingly blurred in recent decades, with financial actors taking a growing interest in food and agriculture and agro-food enterprises becoming increasingly involved in financial activities; (2) financialization has reinforced the position of food retailers as the dominant actors within the agro-food system, though they are largely subject to the dictates of finance capital and face renewed competition from financialized commodity traders; (3) financialization has intensified the exploitation of food workers, increasing their workload while pushing down their real wages and heightening the precarity of their positions, and (4) small-scale farmers have been especially hard hit by financialization, as their livelihoods have become even more uncertain due to increasing volatility in agricultural markets, they have become weaker vis-à-vis other actors in the agro-food supply chain, and they face growing competition for their farmland. The paper concludes by identifying themes for future research and asking readers to reimagine the role of finance in food provisioning. 相似文献

This study is the first to examine the background level of male DNA on underpants worn by females in the absence of sexual contact. Here, we examined 103 samples from the inside front of underpants from 85 female volunteers. Samples were examined for the presence of male DNA using NGM SElect and PowerPlex Y23 kits. Only five samples gave a “complete” Y-STR profile, even though 83.5% of our volunteers cohabited with a male. In all cases where a partner reference sample was available, the Y-STR profile matched the cohabiting partner. We have demonstrated that a Y-STR profile is not expected on the inside front of underpants worn by females after social contact alone. The results of this study are informative for evaluating the significance of a Y-STR profile on underpants in cases of alleged sexual assault. 相似文献

Self-harm is widely recognized as a significant adolescent social problem, and recent research has begun to explore its etiology.
Drawing from Agnew’s (1992) social psychological strain theory of deviance, this study considers this issue by testing three hypotheses about the effects
of traditional and cyber bullying victimization on deliberate self-harm and suicidal ideation. The data come from a school-based
survey of adolescents in a rural county of a southeastern state (n = 426); 50% of subjects are female, their mean age was 15 years, and non-Hispanic whites represent 66% of the sample. The
analysis revealed that both types of bullying are positively related to self-harm and suicidal ideation, net of controls.
Moreover, those relationships are partially mediated by the negative emotions experienced by those who are bullied and partially
moderated by features of the adolescent’s social environment and self. Regarding the latter, exposure to authoritative parenting
and high self-control diminished the harmful effects of bullying victimization on self-harm and suicidal ideation. The article
concludes by discussing the implications of these conclusions for future research and for policy efforts designed to reduce
self-harm. 相似文献

This study examined the effects of neighborhood context on juvenile recidivism to determine if neighborhoods influence the
likelihood of reoffending. Although a large body of literature exists regarding the impact of environmental factors on delinquency,
very little is known about the effects of these factors on juvenile recidivism. The sample analyzed includes 7,061 delinquent
male juveniles committed to community-based programs in Philadelphia, of which 74% are Black, 13% Hispanic, and 11% White.
Since sample youths were nested in neighborhoods, a hierarchical generalized linear model was employed to predict recidivism
across three general categories of recidivism offenses: drug, violent, and property. Results indicate that predictors vary
across the types of offenses and that drug offending differs from property and violent offending. Neighborhood-level factors
were found to influence drug offense recidivism, but were not significant predictors of violent offenses, property offenses,
or an aggregated recidivism measure, despite contrary expectations. Implications stemming from the finding that neighborhood
context influences only juvenile drug recidivism are discussed. 相似文献

The adage that “it is always easier to fight the last war” is one that readily can be applied to the United States and its armed forces for not predicting the scale and type of operations encountered in the occupations of Iraq and Afghanistan. This article argues that the lack of preparation in the post-invasion phases arose from an institutional attachment to a preferred paradigm of warfare, as exemplified by the Persian Gulf War of 1991. This paradigm, though, has been substantially resurrected and re-configured to suit the fighting preferences of the American armed forces in its protracted encounters in Iraq and Afghanistan. Far from re-orienting its organization and mindset to meet the challenges of so-called counterinsurgency campaigns, as much current advocacy maintains, the military has reverted to the form of warfare it knows best. 相似文献
