Over the last decades, indigenous movements have propelled the political empowerment of historically marginalized groups in Latin America. The Maya struggle for ethnic equality in Guatemala, however, since its reawakening during the peace process, has reached an impasse. Based on field research consisting of dozens of elite interviews, this article analyzes the patterns of and obstacles to present‐day Maya mobilization. It combines movement‐internal and ‐external factors in an overarching theoretical argument about indigenous movements' capacity to construct strong collective voices. In the Guatemalan case, organizational sectorization, the lack of elite consensus on key substantive issues, and unclear alliance strategies compromise the effectiveness of horizontal voice among Maya organizations. These problems are exacerbated by the lasting effects of the country's unique history of violence and state strategies of divide and rule, preventing the emergence of a strong vertical voice capable of challenging the Guatemalan state. 相似文献

Over recent decades, emigrants have gained expanded voting rights on a global scale. Despite the normative debates about this issue, there are few empirical studies on why states decide to implement external voting and how electoral systems perform. This article seeks to fill this gap by looking at the Portuguese case. Our study suggests that a combination of political and socio-economic factors explains the implementation of external voting. On the other hand, the interests of political parties and the low level of civil society engagement are key to determining the failure of electoral reforms and the attempts to overcome the shortcomings of external voting. 相似文献

The aim of this study was to assess the effectiveness of two current on-site oral fluid (OF) drug detection devices (OraLab and Dräger), as part of the Spanish participation in the Roadside Testing Assessment Project (ROSITA Project). The study was done in collaboration with the Spanish Traffic Police, in Galicia (NW Spain), during 2004 and 2005. A total of 468 drivers selected at the police controls agreed to participate through informed consent. In addition, saliva samples were collected and sent to the laboratory to confirm the on-site results. For this purpose, two different analytical liquid chromatography–mass spectrometry (LC–MS) methods were used to detect 11 drugs or metabolites in a 300 μL sample. Simultaneous analysis of morphine, 6-acetylmorphine, amphetamine, methamphetamine, MDA, MDMA, MDEA, MBDB, cocaine and benzoylecgonine was carried out using 100 μL of oral fluid, after an automated solid phase extraction. A different LC–MS method was performed to detect Δ9-THC in 200 μL of oral fluid using liquid–liquid extraction with hexane at pH 6. Both methods were fully validated, including linearity (1–250 ng/mL, 2–250 ng/mL) recovery (>50%), within-day and between-day precision (CV < 15%), accuracy (mean relative error < 15%), limit of detection (0.5 and 1 ng/mL), quantitation (1 and 2 ng/mL) and matrix effect. All of the positive cases and a random selection of 30% of the negatives were analyzed for confirmation analysis. Good results (sensitivity, specificity, accuracy, positive predictive value and negative predictive value > 90%) were obtained for cocaine and opiates by OraLab, and for cocaine by Dräger. However, the results for the other compounds could be improved for both detection devices. Differences in the ease of use and in the interpretation mode (visual or instrumental) were observed. 相似文献

Drinking from the Talent Pool: A Resource Endowment Theory of Human Capital and Agency Performance 下载免费PDF全文
This article advances a resource endowment theory of human capital and performance in government organizations. Building on research on human capital and firm location in business economics and task complexity in public management, the authors argue that an agency's ability to implement policy is determined both by its scale and by the human capital of the population from which it draws its employees. The authors cast labor as a factor of production in public agencies and argue that access to higher‐quality labor improves government effectiveness. The effect of human capital on performance is especially pronounced when agencies are charged with the implementation of technically complex tasks. The empirical subject is U.S. municipal water utilities’ compliance with the Safe Drinking Water Act. Comparing records of compliance with more and less complex regulatory requirements provides evidence consistent with the general model. The findings carry important implications for public management and policy design. 相似文献

Objectives
Examine the long-term effects of two childhood universal prevention programs on adolescent delinquency, substance use, and antisocial behavior.Methods
The cluster randomized controlled trial involved 56 schools and 1,675 children in Zurich, Switzerland. Two evidence-based interventions, namely the social-emotional skills program Promoting Alternative Thinking Strategies (PATHS) and the cognitive-behavioral parenting program Triple P, were implemented during the first two years of primary school, at ages 7 and 8 years. Outcomes were measured at ages 13 and 15 years, and included youth self-reports and teacher assessments. Multilevel models were used to account for the clustered nature of the interventions. Effects were estimated with the inclusion of baseline covariates.Results
Across 13 outcomes related to delinquency, substance use, and antisocial behavior at ages 13 and 15 years, only two non-negligible effects were found. The first was a reduced prevalence of police contacts in the PATHS condition [effect size (ES)?=??0.225). The second was a difference in competent conflict resolution skills in the combined PATHS?+?Triple P condition compared to the context (ES?=?0.259), but in the unexpected direction: participants in the combined treatment appeared to be less competent than their control group peers. All other effects were either statistically non-significant or negligible in size (i.e., ES?<?|0.200|).Conclusions
Even “evidence-based” interventions may have few long-term effects on delinquency, substance use, and antisocial behavior. Our findings add to the small literature on the long-term effectiveness of early universal prevention in field settings.79.

Eight Y-chromosome STRs were investigated in a male population sample from El Salvador. Complete Y-chromosomal STRs haplotypes were obtained in 121 individuals, among which 107 different haplotypes were observed. The two most common haplotypes were shared by approximately 4% of the sample, while 100 haplotypes were unique. The gene diversity was 0.9883 and the discrimination capacity was 0.8926. The combined Y-chromosome STR polymorphisms provide a powerful discrimination tool for routine forensic applications. 相似文献

Increasingly, principal investigators are tasked by funding agencies not only to expand knowledge in a particular field of inquiry, but also to manage and coordinate sets of diverse actors, including researchers with different disciplinary backgrounds and with different institutional affiliations. This paper addresses how principal investigators organize and manage sets of diverse researchers in university research centers. The premise of the paper is that centers possessing “management knowledge”—as embodied in principal investigators themselves and in colleagues and subordinates (e.g. past experiences in centers, industry, formal management training and professional experience)—will demonstrate different structural and managerial characteristics when compared to centers without management knowledge. Based on interviews and documents for a purposive sample of centers established by the US National Science Foundation, the study investigates the organization and management of centers as a function of the presence and type of management knowledge of the center directors across multiple cases. Implications for addressing common challenges to team science in university research centers and comparable arrangements are discussed. 相似文献
