Crop genetic diversity and poverty are linked: first, resource-poor farmers often maintain genetic diversity; and second, crop diversity, when properly valued by the market, has the potential to alleviate poverty. This article examines this supposition by drawing on three case studies of the intersection of the market with poverty and maize diversity in Mexico. These suggest that the bulk market for maize offers little room for maize landraces (local maize varieties known as criollo maize), in that it does not reward qualitative variation in maize grain and instead presents incentives that make planting ‘improved’ maize germplasm the rational economic choice for small-scale farmers. Meanwhile, attempts to add value to maize landraces via market differentiation have had varying success. Although there is potential for differentiated markets to contribute to successful business models and poverty alleviation, these cases exhibit trade-offs between product consistency, investment of labour and resources, and genetic-diversity conservation. 相似文献

Women's movements made important contributions to ending the period of authoritarian rule in Latin America, but their participation in the reconstruction of democratic politics has been more limited than expected. This paper argues that the enormous influence exerted by technocratic elites in the democratization process in Latin America has represented an obstacle to the improvement of women's status in the region. Gender-biased assumptions and practices have been only partially addressed, in part because the policy-making process is under the control of economists, a professional group with a particularly unfriendly stand towards gendered analysis. It is suggested that reforms within economics may help in the task of making democracy more responsive to the demands of women. 相似文献

In this paper, we test the effect of three different criminal deterrence theory policy tools: criminal certainty, severity,
and celerity of punishment. Whereas most criminal deterrence studies in this field focus on the former two components of deterrence
theory, this study also examines the potential deterrent effect of the latter component. Using a time-series design with monthly
data, we estimate the effects of an increase in the threat of punishment for traffic offenses resulting from a general increase
in fines for traffic offenses, an increase in the probability of getting caught with a blood-alcohol concentration (BAC) level
outside the legal limits, and the enactment of an “on-the-spot” fine payment policy in Portugal. We find strong evidence to
support a severity effect. An increase in the statutory severity of sentence maxima for traffic violations leads to a decrease
in accident and injury rates—approximately an average 0.5 percent reduction in monthly accident and injury rates. Changes
in the BAC levels and the mandatory swift payment policy did not produce any convincing deterrence impact.

Hanging is one of the most frequent methods for suicides among young males. This report presents two cases of suicide by hanging on pylons carrying high-voltage power lines. The male victims suffered electrocution while committing suicide. Electrocution was the cause of death in both cases, however in one case blunt force injuries from hanging contributed to death. In these two cases hanging was the intentional method of suicide and it was followed by electrocution. The cases demonstrate that scene investigation, a detailed autopsy with histology, and amamnestic data are essential in the evaluation of suicides by hanging and that the determination of the cause of death remains a challenge in investigating such cases. 相似文献

Allele frequency distributions and population data for 12 Y-chromosomal short tandem repeats (STRs) included in the PowerPlex®Y Systems (Promega) were obtained for a sample of 200 healthy unrelated males living in São Paulo State (Southeast of Brazil). A total of 192 haplotypes were identified, of which 184 were unique and 8 were found in 2 individuals. The average gene diversity of the 12 Y-STR was 0.6746 and the haplotype diversity was 0.9996. Pairwise analysis confirmed that our population is more similar with the Italy, North Portugal and Spain, being more distant of the Japan. 相似文献

This study seeks to (a) identify and measure the lifetime exposure to community violence of 137 African American and Latino middle school students from a low income neighborhood and apply numerical weights to each violent event; (b) examine the relationship between the objective severity of child self reported violence exposure and the child's subjective perception of the most bothersome event; and (c) examine the relationship between child's exposure and posttraumatic stress disorder (PTSD). Results highlight that students' designation of their most bothersome exposure to community violence did not correspond to the most severe violent event they experienced. Regression analyses reveal the weight of the most severe event explains a larger percentage of the variance in PTSD compared with the relationship to victim, level of exposure, weight of the most bothersome exposure, and cumulative weight of all exposure. This study underscores the importance of assessing a child's perception of violent events. 相似文献

This article provides an overview of the various forms of proceedings available within 11 European criminal justice systems and reflects upon their core features. It also provides a picture of how far alternative, non-criminal proceedings are used by some of the systems as a different path to imposing a state reaction upon wrong-doers. 相似文献

Legal context: This article attempts to analyse the patent ambush scenarioin the context of both competition law and IP rights under USand EC law. The regulators such as the US FTC and European Commissionattempt to combat the abuses, however the legal tools availablerequire a very difficult balancing act between patent law (whichprotects innovation) and competition law (which attempts tohamper abuse of the free market rules). Key points: The patent ambush scenario employed within a standard-settingorganization poses an important threat of jeopardizing the goalsof achieving a common standard. The response to the problemconcentrates on ensuring that the rules applicable to standard-settingorganizations' members prevent abuse and/or reaching reasonableand non-discriminatory licensing terms to stop deriving unduebenefits from proprietary technologies embedded in the standard. Practical significance: As the information exchange technologies become increasinglypopular, the need to ensure interoperability between productsof different manufacturers employing these technologies becomescrucial for market success. This consequently increases thedanger of malignant abuse of co-operation within the standardsetting-organizations. The law may need to step in to securetechnological progress free of risks such as the patent ambush. 相似文献
