Urbanization Patterns,Information Diffusion,and Female Voting in Rural Paraguay

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.

Constructing Reform Coalitions: The Politics of Compensations in Argentina's Economic Liberalization

It is frequently argued that the key to "successful" economic liberalization is to marginalize interest groups that profit from existing regulatory regimes. This paper contends that some established interests can craft public policies to protect their rents in the new market setting. The state may shape the interests of social actors and create proreform constituencies out of old populist and interventionist groups. In Argentina, this coalition building was achieved by constructing reform policies that granted rents in new markets to business and organized labor and by deliberately avoiding unilateral deregulation in sectors where reform would hurt traditionally powerful actors. This argument is developed through a comparative analysis of policy reform in the labor market institutions and protected industrial sectors, areas where the costs of deregulation are said to be unavoidable for the established actors.     

Puerto Rico: National security,economic growth and colonialism

Abstract

Puerto Rico's significance for the US state and imperialism has gradually deteriorated. In the context of recent global changes and new developments in the US political economy the logic that justified colonial control cannot be sustained. However, an array of counteracting political and economic forces are conspiring to overcome the altered material and geopolitical conditions that make evident the need for Puerto Rico's decolonization.

Colonialism has given rise to an array of forces that impedes any changes in Puerto Rico's formal political status. Where once the US state, corporate capital and the dominant political forces in Puerto Rico were in relative agreement on sustaining the colonial enterprise, a new constellation of competing forces has emerged. Within Puerto Rico proponents for the status, quo and those who agitate for statehood have reached virtual electoral parity. Monopoly “capital, primarily in Pharmaceuticals, dominates the local economy. However, it is challenged by North American unions and their congressional allies who seek to rescind the lucrative fiscal policies that account for these firms exorbitant profits. Agencies of the US state and congressional committees are at odds on what needs to be done to sustain an unmanageable, increasingly expensive and anachronistic colony.

This essay presents a framework for examining the array of forces and conditions that continue to erode the colonial relation and that explains colonialism's fragility in the current period of global readjustment.

“Sex change” in skeletal remains: Assessing how heat-induced changes interfere with sex estimation

The true impact of heat-induced changes in human bone regarding their sex estimation has not been comprehensively documented having a potentially negative impact on forensic anthropology. The objective of this paper was to evaluate how heat exposure affects sex estimation based on both morphological and metric features. The study focused in both low-to-medium intensity burns and high intensity burns. Selected sexually dimorphic features were analysed in 51 experimentally burnt skeletons from the 21st Century Identified Skeletal Collection. Bones were burnt to maximum temperatures between 450 °C and 1050 °C achieved after 75 to 257 min. Morphological methods tested in this study comprised the recommendations for hipbone features from Buikstra and Ubelaker (1994) and from Bruzek (2002). On the other hand, metric references tested here were the ones from Wasterlain (2000), Curate et al. (2016) and Gonçalves et al. (2013) focused on the humerus, femur, calcaneus and talus. Agreement was tested with Gwet’s AC1 test and was further assessed by calculating the relative amount of perfect agreements. Results demonstrated that heat-induced changes affected not only the scoring of morphological features burnt at high temperatures but also the scoring of features burnt at lower intensities. On the other hand, metric features were only considerably affected in high intensity burns, no major changes being documented for low-to-medium intensity burns. For low-to-medium intensity burns, the Bruzek and Curate et al. methods revealed a better agreement between the pre- and post-burning scores. For high intensity burns, better agreement was obtained by using the Bruzek (2002) and Gonçalves et al. (2013) methods. As expected, heat-induced warping, fracture and metric change had a major impact on the pre- and post-observations’ agreement. Contrary to what has been systematically assumed over the years, this impact is also quite substantial in bones burnt at low-to-medium burn intensities so caution is advised during the analysis of this kind of burnt skeletal material.     

DNA-based and taxonomic identification of forensically important Sarcophagidae (Diptera) in southeastern Spain

Studying dipterans at the scene of a death can provide essential information for interpreting the evidence and help to reconstruct the events happened to a corpse in the past. Molecular tools have been employed for identification at specific levels in the cases of cryptic species or poorly conserved specimens. Identification of specimens is essential in forensic entomology since each species has a specific growth rate, which determines the calculation of the minimum post mortem interval (minPMI). In addition, phylogeographic reconstruction within a species can help to differentiate the haplotypes from a geographic area, thereby helping to clarify the possible relocation of a corpse. The morphological identification of Sarcophagidae species is often difficult, especially for the females. This is an important Diptera family since some of its species are among the first to reach a corpse, especially in warm areas. In this study, we compared the sarcophagids found in human corpses in forensic cases in Alicante (southeast of Spain) with specimens collected from baited traps in the same area and surrounding provinces. In total, 189 specimens were collected, comprising 72 from forensic cases and 117 from baited traps. Molecular identification was conducted by sequencing the cox1 mitochondrial gene and analyzing the sequences using ABGD, GMYC, and BIN species delimitation methods. The median joining algorithm in the PopART program was used to construct phylogeographic networks. Eight species in the family Sarcophagidae were identified. The most widely collected species were Sarcophaga argyrostoma and Sarcophaga tibialis. The haplotype networks obtained for these species did not indicate a clear geographic distribution of haplotypes. The S. argyrostoma samples from Alcoy were clearly isolated. The results demonstrated that this method is useful for identifying Sarcophagidae samples in forensic investigations and it can be employed for minPMI estimation.
