Profiling of volatile impurities in tetramethylenedisulfotetramine (TETS) for synthetic-route determination

In recent years, alcohol consumption has been considered an important public health problem. Ethanol, the alcohol used in beverages, is a drug that affects the central nervous system (CNS) and impairs driving skills and co-ordination, increasing risk of deaths and injuries derived from crashes and road accidents. Consumption of alcoholic beverages is implicated with premature deaths, injuries and damages caused by motor vehicle crashes, which result in high costs to government and society. Considering that alcohol consumption is the main responsible factor for deaths and disabilities in young people, the aim of this work was to evaluate the prevalence of blood alcohol in offenders and/or fatal and non-fatal victims of traffic occurrences in the region of Ribeir?o Preto, S?o Paulo State, from 2005 to 2007. The results revealed that in 2134 cases investigated, blood alcohol positivity was generally found in young adults, 25-45 years old and male. The study showed the high risk of drinking and driving and the importance in establishing actions of prevention and intervention to promote the reduction in the number of traffic occurrences related to consumption of alcoholic beverages.     

Legislative Twitter Style: Electoral Vulnerability,Social Media,and Constituency-Building in Large Multimember Electoral Systems

How do legislators use social media to cultivate their constituencies in large multimember electoral districts? Colombia's Senate nationwide district offers a suitable case to examine how lawmakers, through their behaviour on Twitter, geographically target their audiences. We employ microblog user geolocation methods which infer locations using textual content in order to identify where Colombian senators' Twitter ‘home’ is. We find that senators' location targeting on Twitter largely mirrors the geographical distribution of their votes. Deviations from that pattern mostly stem from their vulnerability to intraparty competition and the nature of their parties' organisation.     

Non-monetary obstacles to medical care: Evidence from postpartum contraceptives

We use changes to Medicaid immediate postpartum policy to test whether non-monetary costs are meaningful obstacles to health care. Medicaid in several states currently covers long-acting reversible contraceptives (LARCs, including IUDs and implants) immediately following delivery of a child, eliminating much of the time-cost and stress associated with obtaining a LARC. Postpartum LARCs can reduce unintended and short-interval pregnancies, which are associated with adverse neonatal outcomes. Births that occur in Catholic-owned hospitals are an ideal control group, because these hospitals are prohibited from offering family-planning services, including LARCs. Using difference-in-differences and individual-level administrative data from Louisiana and New York, we find eliminating non-monetary obstacles increases take-up of a high-value and highly effective form of contraception. Additionally, we find no evidence of crowd-out of outpatient LARCs.     

Development Cooperation and Dependency: An Analysis of Brazilian-Spanish Cooperation in Latin America Between 2010 and 2018

Based on analysis of Brazilian-Spanish cooperation in Latin America, this article aims to contribute to the discussion on whether South–South Cooperation (SSC) represents an alternative model with specific and differentiated objectives, or if it largely reproduces the constraints and interests traditionally associated with the North–South model, but with new institutions and actors. We start by analysing the main criticisms levelled at cooperation in the literature, emphasising the identification, review and comparison of the mechanisms of domination and dependency that derive from the bilateral and multilateral practices of traditional development cooperation. We then construct a synthetic dependency index to measure the ability of Spain and Brazil – as representative cases of North–South Cooperation (NSC) and SSC with Latin America – to influence the foreign trade, investment and foreign policy decisions of aid recipients, and to empirically contrast the lower level of verticality that much of the available literature assumes about SSC schemes. The empirical analysis suggests significant differences between NSC and SSC in terms of their ability to reproduce dependency patterns and validate the discourse that tends to identify the latter as an alternative cooperation model.
