This study provides one of the first causal estimates of both the personal and partisan incumbency advantages. Using data on six local elections taking place during the last 20 years in 278 municipalities in Portugal, it relies on a reform introducing mayoral term limits as a natural experiment that creates exogenous variation on the incumbency status of officeholders while holding the incumbency status of the party constant. A new methodology combining two quasi‐experimental methods, the regression discontinuity and the difference‐in‐discontinuities designs, allows for a credible estimation of the independent personal and partisan returns to incumbency. Results causally identify the personal effect as the driver of the incumbency advantage. 相似文献

A qualitative and quantitative analytical method was developed and validated for the determination of 49 licit and illicit drugs in oral fluid. Small oral fluid samples, volume 1mL, were collected from volunteers using a modified Omni-Sal device and the analytes were extracted from an oral fluid/buffer mixture using a single Bond Elut Certify solid phase extraction cartridge. Liquid chromatography-tandem mass spectrometry (LC-MS-MS) and gas chromatography-repetitive full scan mass spectrometry (GC-MS) were used in parallel to analyze the extracts for the targeted drugs. Extracts were analyzed by GC-MS in their underivatized form and as their pentafluoropropionyl derivatives. Deuterated internal standards were used for quantification of drugs of abuse by LC-MS-MS to minimize matrix effects. Methadone-d(9) and tumoxetine were used as the internal standards for quantification of non-derivatized and derivatized analytes respectively by GC-MS. Linearity was demonstrated over the range 5-200 ng/mL and limits of detection were less than 4 ng/mL for each drug analyzed. The method demonstrated acceptable recoveries for most of the analytes and good intra- and inter-day precision. Acquisition of data by repetitive full scan GC-MS allows the addition of further analytes to the target menu. 相似文献

Toronto prides itself both on being diverse and on celebrating rather than merely tolerating diversity. Urban diversity has been studied by demographers, sociologists, and planners, but sociolegal analyses of the negotiation of diversity are scarce. The study described here has three elements: a study of the Toronto Licensing Tribunal, a challenge to the property standards by‐law, and a campaign to reform the rules governing street food. The key substantive finding of the research is that municipal legal processes, in a city that takes pride in its diversity, still work to effect and naturalize distinctly ethnocentric norms. The content of (some) norms is subject to revision but the normative power of law as such remains unchallenged. Methodologically, the article, inspired by Bruno Latour and Actor Network Theory, shows the usefulness of treating local legal processes as a series of networks in which nonhuman objects (such as weeds, courtroom Bibles, and hot dogs) can sometimes be protagonists of legal dramas rather than mere objects. 相似文献

We use a field experiment to evaluate the impact of two informational get‐out‐the‐vote campaigns to boost female electoral participation in rural areas of Paraguay. We find that public rallies had a small and insignificant effect either on registration or voter turnout in the 2013 presidential elections. Households that received door‐to‐door canvassing treatment were 4.6 percentage points more likely to vote. Experimental variation on the intensity of the treatment at the locality level allows us to estimate spillover effects, which are present in localities that are geographically more concentrated, which may favor social interactions and diffusion of information. Reinforcement effects on the already treated population are twice as large as diffusion effects on the untreated. Our results underscore the importance of taking into account urbanization patterns when designing informational campaigns. 相似文献

The Revised Conflict Tactics Scales (CTS2) are widely used to measure intimate partner aggression. Various aspects of the
CTS2 and its subscales have been examined, e.g. factor structure, internal consistency, and validity, but little or no evidence
exists regarding the stability of the self-report of aggression on the CTS2 This study examines the stability of reports of
aggression against a partner on the CTS2 among 82 men court-mandated to a batterer intervention program. At both testing times
men reported on aggression occurring in the year prior to beginning treatment. Using variety scores, stability of report was
strong for psychological aggression (r = 0.69), physical assault (r = 0.76), injury (r = 0.70), and negotiation (r = 0.60), but weaker for sexual coercion (r = 0.30). Implications for the use of the CTS2 in court-mandated populations are discussed.

An analysis of the National Survey of Violence Against Women (2006) in Mexico was performed to estimate the prevalence and the associated factors of women suffering intimate partner violence (IPV) that report their aggressor by severity of violence. Women aged 15 years or older who reported IPV were analyzed by using logistic regression models. Prevalence of IPV was 33.33 %, 64.11 % of them were classified as non-severe violence (NSV) and 35.89 % as severe violence (SV). Women with SV reported the aggressor more often (24.69 % vs. 6.08 % of NSV). Variables associated with reporting the aggressor for both NSV and SV were having children living in the household, higher socioeconomic status, frequent alcohol consumption by the partner, and health personnel informing women that they were experiencing IPV. We can conclude that a low percentage of women reported IPV. Greater efforts should be made to empower women so they can effectively execute their right to live a life free of violence. 相似文献
