Identity documentation is essential to secure the rights, benefits, and services that modern states provide. Historically, significant numbers of poor Brazilians lacked core documents, beginning with a birth certificate. In recent years the government has conducted a campaign to rectify this situation. We explore why the state left so many Brazilians without a birth certificate previously and why it became intent on registering all births, as reflected in recent efforts to facilitate the process. Key in this regard is the movement from a social policy orientation that excluded poor Brazilians in the informal sector to one aimed at including them.  相似文献

Research on executive‐legislative relations in Latin America has focused on the impact of minority presidents and multiparty legislatures on legislative productivity. But an additional deadlock scenario, the blocking of a majority president by a minority through filibustering, has been understudied. This article analyzes filibustering in Costa Rica and explains the legislative paralysis in the wake of the nation's transition to a multiparty system in 2002. Legislative paralysis is seen as a product of the interaction between increased legislative fragmentation and polarization and the legislature's preexisting rules of procedure, which enable legislators easily to block bills they oppose, even when those bills are supported by supermajorities. This argument is tested through a comparison of major economic reforms in the 2000s to the reforms tackled in the 1990s. The role of filibustering, well acknowledged in U.S. politics, should also be studied in comparative politics.  相似文献

Medical examiners function primarily to determine cause and manner of death, and to document illness and injuries. Equally important, however, is the role of providing family members with the initial tools to work through the grief process. By initiating contact with the family, facilitating access to other appropriate services and by making provisions for adequate viewing and meeting facilities, we fulfill these ethical duties and carry out our responsibilities as physicians. We hope to fill some of the void that exists in the forensic medical literature with this presentation and generate awareness for the neglected role of grief intervention.  相似文献

Although more universities are developing policies for students regarding consent for sexual behavior in response to the problem of sexual violence on campus, many students seem either unaware of these policies or what they mean for actual behavior. Policies are only as effective as peoples' understanding and use of them. The current study aimed to evaluate the utility of a prevention education program focused on teaching students about consent. Two hundred and twenty undergraduates, composing a control group, a shorter treatment group, and a longer one, participated in the study. The findings showed the greatest knowledge gain for participants in the longer treatment group that included a discussion of the policy and participation in an activity dealing with its implications. Implications and future research directions are discussed.  相似文献

Marijuana, a drug derived from the Cannabis sativa L. plant, is the world's most consumed illicit drug. In this paper, a total of 156 marijuana samples seized in the state of Espírito Santo (ES), Brazil were studied and analysed by proton nuclear magnetic resonance (1H NMR) spectroscopy to identify the major cannabinoids present. A crude extract of all samples was purified using high performance liquid chromatography so that these compounds could serve as reference substances. Nine fractions were obtained and analysed by 1H NMR and gas chromatography–mass spectrometry (GC–MS), with five presented cannabinoids. ?9-THC (Δ9-trans-tetrahydrocannabinol), ?9-THCA (?9-tetrahydrocannabinolic acid), ?8-THC (?8-tetrahydrocannabinol), 11-hydroxycannabinol, CBV (cannabivarin), and CBN (cannabinol) were found, and their chemical structures were confirmed by GC–MS. The latter compound was obtained with high purity (≈100%), while the others were obtained as less complex mixtures with purity higher than 75% (except for Δ8-THC). Principal component analysis (PCA) was used on the 1H NMR spectra of the 156 samples, and it was found that the samples were grouped according to the months, differentiating into two groups (from July 2014 to January 2015 and from February 2015 to July 2015), where non-grouping was observed from four macro-regions of the ES state (North, Central, Metropolitan, and South). The chemical profile of the seized samples was correlated to the 1H NMR spectrum of an isolated CBN sub-fraction, in which the group formed by samples seized in the year 2015 presented lower CBN content in the chemical composition. From the PCA score plot, two groups of samples were confirmed using the partial least squares discriminant analysis and orthogonal projections to latent structures classification methods.  相似文献

This article examines marriage patterns among immigrants and their children as a way to analyze the interplay of primary social networks and local conditions in the social adaptation of two communities of Portuguese immigrants in Argentina. Its main focus is on the factors involved in marriages within the same ethnic group and their evolution over time from a comparative perspective. The analysis considers aspects of marital selection in the main places of origin of the immigrants in the Algarve, southern Portugal, and their influence in the places of settlement; the factors that influenced the selection of spouses in both communities by gender and over time; and the changes from the first to the second generation. Factors, such as gender, the nature and rhythm of immigration, and the occupation of the immigrants and their families, proved very important in marital selection. Environmental factors were also significant. Oil production dominated Comodoro Rivadavia, while intensive family farming in a suburban setting characterized Villa Elisa. Through the comparative analysis of these two contrasting, receiving societies, the article examines the interplay between primary social networks based on national and ethnic origin and socioeconomic local conditions.  相似文献

A second collaborative exercise on RNA/DNA co-analysis for body fluid identification and STR profiling was organized by the European DNA Profiling Group (EDNAP). Six human blood stains, two blood dilution series (5-0.001 μl blood) and, optionally, bona fide or mock casework samples of human or non-human origin were analyzed by the participating laboratories using a RNA/DNA co-extraction or solely RNA extraction method. Two novel mRNA multiplexes were used for the identification of blood: a highly sensitive duplex (HBA, HBB) and a moderately sensitive pentaplex (ALAS2, CD3G, ANK1, SPTB and PBGD). The laboratories used different chemistries and instrumentation. All of the 18 participating laboratories were able to successfully isolate and detect mRNA in dried blood stains. Thirteen laboratories simultaneously extracted RNA and DNA from individual stains and were able to utilize mRNA profiling to confirm the presence of blood and to obtain autosomal STR profiles from the blood stain donors. The positive identification of blood and good quality DNA profiles were also obtained from old and compromised casework samples. The method proved to be reproducible and sensitive using different analysis strategies. The results of this collaborative exercise involving a RNA/DNA co-extraction strategy support the potential use of an mRNA based system for the identification of blood in forensic casework that is compatible with current DNA analysis methodology.  相似文献

The article discusses the limits and possibilities of school empowerment within education systems plagued by pervasive patronage politics. The analysis focuses on reform initiatives implemented by Brazilian sub‐national governments throughout the 1980s and 1990s to allow for the election of school principals by parents, teachers and students. Until the implementation of this reform, state and local authorities had relied on the school system as a source of patronage resources, and principals were nominated according to political criteria. The new system of democratic school management was expected to undermine this patronage‐based system and foster community participation in school decisions. The article relies on secondary evidence to assess the impact of school elections in what concerns the participation of parents, students and teachers in school affairs and the relationship between schools, party politicians and education administrators. It concludes that high levels of social inequality and the lack of a universalistic and effective system of welfare provision constitute serious obstacles to the empowerment of disadvantaged groups in developing societies such as Brazil. On the other hand, the article argues that school empowerment has the potential to undermine resilient patronage structures, by introducing universalistic mechanisms of decision‐making and making school administrators more accountable to their constituencies.
