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

State repression is a prominent feature of nondemocracies, but its effectiveness in quieting dissent and fostering regime survival remains unclear. We exploit the location of military bases before the coup that brought Augusto Pinochet to power in Chile in 1973, which is uncorrelated to precoup electoral outcomes, and show that counties near these bases experienced more killings and forced disappearances at the hands of the government during the dictatorship. Our main result is that residents of counties close to military bases both registered to vote and voted “No” to Pinochet's continuation in power at higher rates in the crucial 1988 plebiscite that bolstered the democratic transition. Potential mechanisms include informational frictions on the intensity of repression in counties far from bases and shifts in preferences caused by increased proximity to the events. Election outcomes after democratization show no lasting change in political preferences. 相似文献

Science, Technology, and Innovation (STI) have been considered as critical tools in development processes, gaining growing importance in the public policy agenda. We assert that an intersubjective agreement about STI policy has emerged in Latin America from the beginning of the twenty-first century. This operates as a developmental convention which is based on a hybrid theoretical rationale from neoclassical economics and the innovation systems approach. This process has been analyzed from different perspectives of innovation and political economy studies. However, as far as we know, the role of political parties in the construction and reproduction of STI conventions has not been studied. After illustrating the general assertion with stylized facts from the whole Latin American region, we study the platforms that Uruguayan political parties presented in the national elections between 2004 and 2019. Text analysis techniques show that platforms of both left- and right-wing political parties were embedded in the current STI policy convention. However, critical discrepancies emerge in relation to policy implementation—the positive and negative agendas—which show that there has been political competition regarding the role of the state and of markets. This leads us to conclude that even though one can observe a shared set of building blocks on STI policy and development, there is competition within the current convention, suggesting that any agreement is illusory. 相似文献

The aim of this article is to introduce a novel view on how to evaluate the share of power held by judges in judicial governance. Its contribution to court administration and the regulation of judges is three-fold. First, it provides a novel empirically tested conceptualization of judicial governance that includes 60 competences grouped into eight dimensions (ranging from selection and education of judges to case allocation and publication of judicial decisions). Second, it proposes a new Judicial Self-Governance (JSG) Index that measures how much power domestic judges hold in these eight dimensions of judicial governance. Third, by applying the JSG Index to the longitudinal data for Germany, Italy, Czechia, and Slovakia this article demonstrates that the Judicial Council model is not the only institutional model of judicial governance leading to the empowerment of judges. This means that judges can hold many powers without the existence of judicial councils and even in the Ministry of Justice model. 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.

Examination of various SIM cards and smart card devices indicates that data may be retained in SIM card memory structures even after heating to temperatures up to 450 degrees C, which the National Institute of Standards and Technology (NIST) has determined to be approximately the maximum average sustained temperature at desk height in a house fire. However, in many cases, and certainly for temperatures greater than 450 degrees C, the SIM card chip has suffered structural or mechanical damage that renders simple probing or rewiring ineffective. Nevertheless, this has not necessarily affected the data, which is stored as charge in floating gates, and alternative methods for directly accessing the stored charge may be applicable. 相似文献

This paper evaluates the breath alcohol concentration (BrAC), nausea (feeling of being slightly intoxicated) and subjective driving performance after ingesting a moderate dose of alcohol in the presence of a light meal, which intends to approach a social drinking setting. 119 healthy individuals (69 males and 50 females, aged 21.7+/-3.0) ingested three glasses of wine (95mL each) and their BrAC was determined by an Alcotest 7410 at 15, 30, 45, 60, 90 and 120min post-drinking. 46% of females and no male subjects exceeded a BrAC of 0.25mg/L, the legal limit for driving fixed by some Western countries. 53% of the study population felt nausea during the experimental session and 20% self-reported impairment of their driving skills. In both cases these subjective effects were more pronounced in females. The major determinants of mean BrAC were time post-drinking, gender (male) and body mass index (BMI), all these variables being inversely associated. Females and individuals with a BMI lower than 22.5kg/m(2) were at an increased risk of exceeding the legal limit of BrAC. The feeling of nausea was significantly associated with gender (females), the ingestion of up to 2 drinks on weekdays, and having exceeded a BrAC of 0.25mg/L during the experimental study. The main predictor of self-perception of impaired driving skills was the feeling of nausea, followed by a BrAC in excess of 0.25mg/L. In conclusion, both females and subjects with lower BMI are at an increased risk of exceeding the legal limit of BrAC after moderate alcohol consumption resembling a social drinking setting. 相似文献

The report describes a fatal outcome in a 5-year-old male who died after drinking a fatal dose of ethanol at the party held by his parents. Urine and blood alcohol level of the deceased was 0.4 and 0.5 g/dL, what might explain the sudden death of the child. In addition, the analysis of the boy's hair demonstrated the presence of ethyl glucuronide (EtG), a marker of alcohol consumption; hair EtG concentration levels indicated that the boy might have occasionally imbibed alcohol prior to death. Pathological lesions of the liver observed in histopathology did not contradict such a hypothesis. 相似文献
