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

This research note argues that the “lone wolf” typology should be fundamentally reconsidered. Based on a three-year empirical research project, two key points are made to support this argument. First, the authors found that ties to online and offline radical milieus are critical to lone actors' adoption and maintenance of both the motive and capability to commit acts of terrorism. Second, in terms of pre-attack behaviors, the majority of lone actors are not the stealthy and highly capable terrorists the “lone wolf” moniker alludes to. These findings not only urge a reconsideration of the utility of the lone-wolf concept, they are also particularly relevant for counterterrorism professionals, whose conceptions of this threat may have closed off avenues for detection and interdiction that do, in fact, exist. 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 paper examines the incentive and the consequences of using discriminatory pricing by a monopolist in a rent-seeking economy. It is shown that, even if all consumer groups' demands have identical elasticities at any given price, the monopolist has an incentive to charge a lower price to high pressure consumer groups so as to alleviate their rent-seeking efforts in challenging its monopolistic power. Furthermore, it is shown that by allowing the firm to price discriminate total welfare may increase, even if all rent-seeking expenditures are completely wasteful. 相似文献

Abstract: The “will of the people‘’ is considered to be the highest authority in a democracy and said to be the driving force behind public policies. Yet not many past studies have assessed the level of citizen satisfaction with government services and identified ways of improving service delivery. At a municipal level, there is even less emphasis on measuring consumer satisfaction. This study measures citizens' satisfaction with municipal services in a town in Atlantic Canada. A taxonomy of government services based on user experience with the service and heterogeneity of consumer needs was developed and tested. Results indicate that while consumer satisfaction with municipal services is high, it does vary based on the nature of the service. Some action guidelines are suggested at the end of the paper to improve town service delivery. Sommaire: La «volonté du peuple» est considérée comme étant la plus haute autorité dans une démocratice, et l'on dit même que c'est elle qui est à l'origine des politiques publiques. Pourtant, peu d'études ont examiné le niveau de satisfaction du citoyen en ce qui concerne les services gouvernementaux et ont tenté de cerner les moyens permettant d'améliorer ces services. Au niveau municipal, on fait encore moins d'efforts pour mesurer la satisfaction des consommateurs. La présente étude mesure la satisfaction des citoyens à l'égard des services municipaux dans une ville située dans la région Atlantique du Canada. Une taxonomie des services gouvernementaux basée sur l'expérience des utilisateurs et sur l'hétérogénéité des besoins des consommateurs a été mise au point et testée. Les résultats indiquent que, bien que la satisfaction des consommateurs face aux services municipaux soit élevée, elle varie selon la nature de services. À la fin de l'article, on suggère quelques lignes directrices pour améliorer la prestation de services des villes. 相似文献

Fraudulent substitution of a page within a multiple page document such as a will or business contract, the counterfeit manufacture of paper banknotes, and linking ransom or extortion notes have all been the focus of criminal investigations at one time or another. In a recent homicide investigation, document examiners were requested to compare a threatening letter received by a business partner of the deceased with paper samples seized under warrant from a suspect's house. Through a quantitative elemental analysis of the concentrations of nine elements (Na, Mg, Al, Mn, Sr, Y, Ba, La, and Ce) within the questioned and specimen documents, determined by inductively coupled plasma-mass spectrometry (ICP-MS), it was concluded that (i) the paper of the threatening letter originated from a different source to that of the paper seized from the suspect's house and (ii) all six pages of paper seized from the suspect's house originated from the same source. This discrimination of paper is presented as both a statistical t-test analysis (99.9% confidence limit) as well as construction of an elemental fingerprint for individual replicates within the questioned and specimen sample populations. This is the first reported use of the comparison of the elemental composition of document paper, determined by ICP-MS, to assist in a criminal investigation. 相似文献

Prehistoric Polynesian skeletal remains are frequently being recovered in New Zealand due to the increasing pace of urbanisation. Since such material must often be reinterred quickly, it is important that the sex of individuals be determined from the remains in a relatively short time. For this purpose, discriminant function analysis was utilised for sex determination of prehistoric adult New Zealand Polynesian tali (24 males and 27 females). Five measurements were taken and subjected to Statistical Package for the Social Sciences (SPSS) discriminant function analysis. For the discriminant functions derived, accuracy of sex determination ranged from 85.1 to 93.3%. Reduction in error over random assignment by sex ranged from 70 to 87%. 相似文献
