Background: Antisocial personality disorder (ASPD) is strongly associated with violence but the effects of other personality disorder (PD) categories are uncertain. Purpose: To investigate associations between 10 DSM-IV PD categories and effects of co-occurring disorders on self-reported violence. Method: Cross-sectional survey of 8397 adults aged 16–74 years in households in Great Britain. Results: ASPD contributed strongly to the burden of violence in the British population. Paranoid and obsessive–compulsive PD made additional independent contributions, and narcissistic PD contributed to intimate partner violence. The prevalence of violence correlated with the number of PD categories. Comorbid alcohol dependence further increased the risk. Conclusions: Risk of violence increases with increasing severity of PD, measured by the number of PD categories, and with co-occurring alcohol dependence. Not all PD categories are associated with violence, and avoidant PD was protective. Identification of targets for future interventions may be obscured using a classification based solely on severity. 相似文献

Objectives
Generally speaking, crime is, fortunately, a rare event. As far as modelling is concerned, this sparsity of data means that traditional measures to quantify concentration are not appropriate when applied to crime suffered by a population. Our objective is to develop a new technique to measure the concentration of crime which takes into account its low frequency of occurrence and its high degree of concentration in such a way that this measure is comparable over time and over different populations.Methods
This article derives an estimate of the distribution of crime suffered by a population based on a mixture model and then evaluates a new and standardised measurement of the concentration of the rates of suffering a crime based on that distribution.Results
The new measure is successfully applied to the incidence of robbery of a person in Mexico and is able to correctly quantify the concentration crime in such a way that is comparable between different regions and can be tracked over different time periods.Conclusions
The risk of suffering a crime is not uniformly distributed across a population. There are certain groups which are statistically immune to suffering crime but there are also groups which suffer chronic victimisation. This measure improves our understanding of how patterns of crime can be quantified allowing us to determine if a prevention policy results in a crime reduction rather than target displacement. The method may have applications beyond crime science.33.

In the face of water scarcity, growing water demands, population increase, ecosystem degradation, or climate change, transboundary watercourse states inevitably have to make difficult decisions on how finite quantities of water are distributed. Such waters, and their associated ecosystem services, offer multiple benefits. Valuation and bargaining can play a key role in the sharing of these ecosystems services and their associated benefits across sovereign borders. Ecosystem services in transboundary watercourses essentially constitute a portfolio of assets. While challenging, their commodification, which creates property rights, supports trading. Such trading offers a means by which to resolve conflicts over competing uses and allows states to optimise their ‘portfolios’. However, despite this potential, adoption of appropriate treaty frameworks that might facilitate a market-based approach to the discovery and allocation of water-related ecosystem services at the transboundary level remains both a challenge and a topic worthy of further study. Drawing upon concepts in law and economics, this paper therefore seeks to advance the study of how treaty frameworks might be developed in a way that supports such a market-based approach to ecosystem services and transboundary waters. 相似文献

Over the last twenty years, Brazil has staked successive claims to regional leadership, with varying explicitness and unclear success. What factors explain the acceptance or rejection of such claims by South American countries? This article summarises the literature on regional powers and frames regional powerhood as arising from geographical belonging, resources, and will to lead; and leadership/followership as stemming from exclusivity, hierarchy/influence, consensus, and provision. By analysing panel data on Brazil and South America from 1995 to 2015, the study concludes that Brasilia enjoyed higher followership in situations characterised by high exclusivity and consensus, and low hierarchy and provision. These conditions were present in South America in the 1990s, thus rendering that decade more receptive to Brazilian leadership. 相似文献

This article analyses the potential for Russian oil export growth through the next decade. It concludes that supply for exports will continue to grow, albeit moderately. The greater or lesser intensity of that growth will depend on the evolution of both production and internal consumption, and especially on the reaction by investors to sector changes promoted by government energy policy. From this analysis, we find three likely scenarios for Russian oil exports. The most positive envisages it will be possible to diversify exports while the most negative suggests that Russia will have scant opportunity to develop an export diversification strategy. 相似文献

Latin America is a region of sharp ethnic inequalities. Uruguay has usually been considered an exception to this pattern, although no data were available to confirm this assumption until recently. This article uses the Household Survey of 2006 to analyze the wage gap between Afro‐descendants and whites through OLS equations, decompositions, and quantile regressions. The analysis finds that discrimination explains approximately 50 percent of the racial wage gap for men and 20 percent for women. Discrimination operates partly through occupational segregation. Differences in schooling are the most important explanatory factor for the rest of the gap. Quantile regressions show that discrimination declines across percentiles for men. 相似文献

Abstract Using survival models, we test whether short-term changes in the labour market affect poverty duration. Data are from the Brazilian Monthly Employment Survey. Such a monthly dataset permits more accurate estimations of events than using annual data, but its panel follows households for a short period. Then methods that control for both right- and left-censoring should be used. The results are as follows: households with zero income are not those with the lowest chances of exiting; changes in aggregate unemployment do not affect poverty duration; and increasing wages in the informal sector has a negative effect on poverty duration. 相似文献

This paper describes the characteristics of Japanese foreign investment in Latin America. In examining FDI patterns, we identify the countries and industries most attractive to Japanese multinational corporations, the preferred modes of entry, and the post-entry performance of these subsidiaries. We find that most Japanese FDI has occurred in Brazil and Mexico, that joint ventures are the most common mode of entry, and that performance varies by country and mode. The observations have implications for three groups of executives: managers of non-Latin American firms, managers of Latin American firms, and public policy makers. 相似文献

This article argues that since 1949, the relationship between Israel and Jordan has depended primarily on their interactions with a Third Actor--identified as Egypt from 1949 to the mid-1970s, and as the Palestinians thereafter. Conflict between Israel and Jordan always follows conflict one or both nations have with the Third Actor. The analysis suggests a cyclical and hierarchical allegiance condition, in which Jordan switches from an alliance with Israel to an alliance with the Third Actor. Jordan cooperates with Israel--even if it itself engages in conflict with the Third Actor--until Israel engages in conflict with the Third Actor, at which point Jordan realigns with the Third Actor against Israel. This analysis suggests that to avoid an Israeli-Jordanian conflict, Israel must reach an agreement with the Palestinians regarding the existence and borders of a Palestinian state. Such an agreement, however, may not guarantee permanent peace between Israel and Jordan, as regional tensions fueled by controversy regarding the existence and legitimacy of the Jordanian Hashemite monarchy may rise again. Thus, even if a Palestinian state were established, the current peace between Israel and Jordan might be transitory. 相似文献

Determination of Herbicides Paraquat,Glyphosate, and Aminomethylphosphonic Acid in Marijuana Samples by Capillary Electrophoresis 下载免费PDF全文
Rafael Lanaro M.Sc. José L. Costa Ph.D. Silvia O. S. Cazenave Ph.D. Luiz A. Zanolli-Filho M.Sc. Marina F. M. Tavares Ph.D. Alice A. M. Chasin Ph.D. 《Journal of forensic sciences》2015,60(Z1):S241-S247
In this work, two methods were developed to determine herbicides paraquat, glyphosate, and aminomethylphosphonic acid (AMPA) in marijuana samples by capillary electrophoresis. For paraquat analysis, sample was extracted with aqueous acetic acid solution and analyzed by capillary zone electrophoresis with direct UV detection. The running electrolyte was 50 mmol/L phosphate buffer (pH 2.50). For glyphosate and AMPA, indirect UV/VIS detection was used, as these substances do not present chromophoric groups. Samples were extracted with 5 mmol/L hydrochloric acid. The running electrolyte was 10 mmol/L gallic acid, 6 mmol/L TRIS, and 0.1 mmol/L CTAB (pH = 4.7). The methods presented good linearity, precision, accuracy, and recovery. Paraquat was detected in 12 samples (n = 130), ranging from 0.01 to 25.1 mg/g. Three samples were positive for glyphosate (0.15–0.75 mg/g), and one sample presented AMPA as well. Experimental studies are suggested to evaluate the risks of these concentrations to marijuana user. 相似文献
