Identifying the Source of Incumbency Advantage through a Constitutional Reform

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.     

The Origins of Security Cooperation in the Southern Cone

Argentine-Brazilian relations have undergone a remarkable transformation over the last two decades, from enduring rivalry to cooperation. Dating back to the late 1970s, security cooperation has been a byproduct of two different sets of factors, strategic and military organizational, that propelled the two countries independently but simultaneously toward peaceful settlement. The 1979–80 settlement of disputes over hydroelectric power and nuclear technology not only ended centuries of militarized competition but established the first institutional structures of what is today one of the world's most durable security regimes.     

Piperazine-like compounds: a new group of designer drugs-of-abuse on the European market

1-Aryl-piperazine compounds are, depending on their substituents, selective for certain serotonin receptors and together with their easy availability and their so-called legal status, this group of psychoactive compounds are potential designer drugs-of-abuse. Internet in that respect is an important source of information and distribution facilities. Because this development may have consequences for the interpretation of future clinical and forensic toxicological case studies, some analytical aspects of 1-benzyl-piperazine (BZP), 1-[4-methoxyphenyl]-piperazine (pMeOPP) and 1-[3-trifluoromethylphenyl]-piperazine (TFMPP) were studied. BZP was not detected by the AxSYM FPIA technology designed to determine amphetamine-like compounds, but had showed some cross reactivity with EMIT d.a.u.. The cross reactivities at 300 and 12,000ng/ml (RS)-amphetamine equivalents were 0.4 and 1.3%, respectively. Although BZP was not identified directly by the REMEDi HS Drug Profiling System, it can be detected by this HPLC/UV scanning system. Using GC/NPD without derivatisation, BZP, pMeOPP and TFMPP can be analysed for and applying GC/MS without or with acetylation or trifluoroacetylation, these compounds can be identified unambiguously. The usefulness of GC/NPD and GC/MS in this respect was demonstrated by the quantitative and qualitative analysis of the content of a capsule with the synthetic stimulant A2, which proved to contain 86.4mg of BZP.     

The Ethic of Diversity: Local Law and the Negotiation of Urban Norms

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.
