Importance of radiological diagnosis applied to necroscopy

The authors evaluate the consequences of incomplete necroscopic examinations wherein it was impossible to apply radiological resources to locate firearm projectiles. The study includes 8185 reports from the Instituto Médico-Legal Afranio Peixoto in Rio de Janeiro, Brazil, representing the totality of corpses processed from January to December 2001; of these, 3122 were gunshot victims, 309 of which were buried with unremoved projectiles, being liable to future judicial reappraisal. During the same period, there were 23 exhumation requests by police authorities, 12 of them querying the existence of projectiles. The authors looked into the formal reasons assumed by the medico legal experts to conclude their reports from incomplete examinations, and suggest that gunshot necroscopic examinations should follow specific protocols, as incomplete autopsies will require further exhumations, at unnecessary additional costs.     

A Political Economy Model of Workers Representation: The Case of Union Elections in Spain

In this article we present a political economy model to analyse the effects of union elections. Union elections are the prerequisite for participating in collective bargaining and they are a unique Spanish institution for union recognition. We apply standard political economy assumptions to model the union elections in order to understand their influence on the dynamics of the unemployment rate. Although union elections give the right to vote to virtually all workers, we show that insider power exists and that it introduces a hysteresis effect on the unemployment rate. In addition, the model shows how the date of the union elections can amplify the business cycle. An empirical analysis confirms the main predictions of the model.JEL Classification: K31, J51, E24     

Portuguese Democratisation 40 Years on: Its Meaning and Enduring Legacies

Abstract

On the fortieth anniversary of the Carnation Revolution, it is pertinent to ask how Portuguese citizens understand their transition to democracy. In this article, some of the main findings concerning the meanings and legacies of 25 April 1974 are presented, drawing on the findings of two surveys focusing on Portuguese attitudes towards 25 April and fielded in 2004 and 2014, respectively, to a representative sample of the Portuguese population. Here we focus on the degree to which the transition is viewed positively and its social and economic legacies. In the final sections, the main findings of the articles in this special issue are discussed through a presentation of the main questions they answer and the new ones they raise.     

Conditional Cash Transfer Programs and Electoral Accountability: Evidence from Latin America

Do conditional cash transfer programs reduce voters' incentives to hold their government accountable for its performance? Studies show that these programs generate considerable electoral returns for the governments responsible for them. One important and unexplored question is whether these popular programs have also changed the landscape of accountability in Latin America. Survey data from 16 Latin American countries that have adopted CCT programs do not offer support for the claim that such programs have a detrimental effect on electoral accountability for corruption and for the economy. Only in countries where CCT programs do not follow strict rules do beneficiaries attribute relatively less weight to the government's economic performance, but this effect is marginal. These findings fill an important gap in the literature and offer reassuring evidence that cash transfers can alleviate poverty while preserving voters' incentives to exercise electoral accountability in crucial areas of government performance.     

The institutionalisation of the Brazilian Chamber of Deputies

ABSTRACT

This article analyses the institutional development of the Brazilian Chamber of Deputies (BCD) from 1826 to the present. Legislature careers, the internal organisation of the BCD, the current system for filling positions within the committees and electoral rules are the objects of this study. The process of development of the BCD should be understood in light of the dynamics of the Brazilian political system, which has undergone significant ruptures of regime, and also in light of the nearly permanent fragility of the democracy, especially of its representative components. It is an institution with legislature career patterns that vary through time, but always point towards opportunities out of the BCD, a stable, hierarchical and complex mode of organisation that currently values parties as distributors of opportunities. It is, above all, an institution that is subject to external influences from other parts of the political system, which diminish its autonomy and self-determination, as shown by the example of the rule for the adjudication of terms. With its 190 years, the BCD has evolved along with Brazilian democracy and today, although boasting a great structure and large resources, it still needs to establish itself as a decisive and permanent actor in driving public policies and communication (parties and government projects) with voters.     

The color of child mortality in Brazil, 1950-2000: social progress and persistent racial inequality

Now that racism has been officially recognized in Brazil, and some universities have adopted affirmative-action admission policies, measures of the magnitude of racial inequality and analyses that identify the factors associated with changes in racial disparities over time assume particular relevance to the conduct of public debate. This study uses census data from 1950 to 2000 to estimate the probability of death in the early years of life, a robust indicator of the standard of living among the white and Afro-Brazilian populations. Associated estimates of the average number of years of life expectancy at birth show that the 6.6-year advantage that the white population enjoyed in the 1950s remained virtually unchanged throughout the second half of the twentieth century, despite the significant improvements that accrued to both racial groups. The application of multivariate techniques to samples selected from the 1960, 1980, and 2000 census enumerations further shows that, controlling for key determinants of child survival, the white mortality advantage persisted and even increased somewhat in 2000. The article discusses evidence of continued racial inequality during an era of deep transformation in social structure, with reference to the challenges of skin color classification in a multiracial society and the evolution of debates about color, class, and discrimination in Brazil.     

Heat Induced Changes to Dental Resin Composites: A Reference in Forensic Investigations?*

The objective was to investigate color change and surface damage in dental resin composites exposed to high temperatures over different time intervals for comparative purposes. Samples were prepared using two resins - Z100(R) (R1) and Charisma (R2), heated at the following temperatures: 200 degrees C, 400 degrees C, 600 degrees C, 1000 degrees C, for 15, 30 and 45 min (n = 104 for each resin sample). Color (DeltaE) and brightness (DeltaL) changes were analyzed by spectrophotometry using the CIE Lab system and surface changes by Scanning Electron Microscopy (SEM). R1 showed more intense color changes after heat exposure than R2. DeltaL values were found to be the best parameter for evaluation of light and color change. A biphasic pattern after thermal exposure was detected, from dark brown to light white. SEM showed more intense alterations in R2 than in R1. These results indicate that the parameters observed in both resins are useful as a guide in forensic analyses.
