Exchange rate volatility in high inflation economies: An econometric study of Poland and Brazil

This paper analyses exchange rate series for Poland and Brazil. The Polish series, related to the period soon after the first liberalizing measures, presents a high volatility which is not accounted for by some selected ‘fundamentals’. The Brazilian series, though also keeping evidence of excessive volatility, is cointegrated with fundamentals similar to those of the Polish case. This raises the issue of a learning process taking place during persistent inflations. Unsuccessful one-shot stabilization plans can reinforce this process, leaving a lasting imprint in the excessive volatility pattern. The message seems clear, though maybe not easy to implement: agents take some time to learn to live in non-stable environments; to avoid this by one-shot measures — if unsuccessful — can have a very high cost and pre-empt future corrections.     

Industry Self-regulation Under Government Intervention

Industry actors (organizations, associations) can influence the way in which firms comply with regulations. This study examines how this influence process is affected by government intervention. Using official, anonymized data from the entire industry of financial intermediation in the Netherlands (N = 8655 firms), we examine how firms’ affiliations with industry actors relate to (1) voluntary actions aligned with improving regulatory compliance (e.g., requesting audits, attending workshops), and (2) law violations. Industry actors are distinguished between trade associations and the industry’s self-regulatory organization (SRO), which is subject to more government intervention. The analysis employs Poisson regressions to explain count variables, and bootstrapping to assess indirect associations. A series of robustness tests focus on relevant sub-samples, employ exact matching to address possible self-selection, and incorporate lagged dependent variables. The association between affiliations with industry actors and law violations is negative and significant. This association is more indirect for trade associations than for the SRO (i.e., it is more strongly mediated by the voluntary actions firms take and which help to improve compliance). These findings go in line with the theory that government intervention makes industry-self regulation more mandated and less voluntary. Under less government intervention, industry actors may promote more voluntary efforts to comply.     

The Persistent Influence of December 2001: Collective Action in 21st-Century Argentina

The protests of December 2001 in Argentina were the most visible manifestation of a larger cycle of contention, which continues to have a substantial influence on the forms, tactics and goals of social movements throughout the country. This paper provides a critical overview of these lasting effects. In particular, we focus on three areas where the consequences of the crisis for collective action have been particularly strong: performative politics, coalition-building, and institutional support for grassroots networks. We conclude by reflecting on the implications for participatory democracy and the consolidation of a highly engaged civil society.     

Alpine Masculinity: A Gendered Figuration of Capital in the Patagonian Andes

This article investigates the Patagonian ecotourism industry and the spatial production of gender privilege. The analysis attends to how the spatial practices of park rangers, tourism guides and climbers create a gendered space of capital accumulation that devalues and marginalises othered subjects – such as women and non-alpine men – within specific domains of nature. Developing the concept of a figuration of capital, this article argues that the ecotourism industry has facilitated the rise of an alpine masculine subject based upon key bodily values: robust physicality, a conservationist ethic and heroic narration about engaging wilderness.     

Standardization of Histological Procedures for the Detection of Toxic Substances by Immunohistochemistry in Dipteran Larvae of Forensic Importance

Immunohistochemistry (IHC) technique is an alternative toxicological analysis to detect drugs in insects of forensic importance, but it requires thorough histological procedures. In this study, we tested different fixatives—phosphate‐buffered paraformaldehyde 4% (PP), Carnoy's fluid (CF), Kahle's solution (KS), ethanol in different concentrations, and ethanol associated to PP and CF, time of fixation and histological processes for dipteran larvae's tissue, aiming to develop a sample preparation protocol for IHC application. A suitable fixation was achieved using PP for 12 and 24 h, CF for 3 h, 70% ethanol for 19 days, and 70% ethanol/CF for 2 h/3 h. Postfixation using negative pressure, two immersions in xylene for 30 min each, and one in xylene plus paraffin for 45 min increased tissue preservation. An immunohistochemical test for cocaine detection was performed using monoclonal benzoylecgonine antibody from mouse, peroxidase‐conjugated anti‐mouse IgG and visualized by 3,3′‐diaminobenzidine method showed these histological procedures didn't compromise antigenicity.     

Anthropological examination in burned body: a retrospective identification case

It is a well-established fact that forensic anthropology has been extremely helpful in identifying thermally altered human remains, especially in recent years. With the improvement of new analytical techniques, the identification success rate has also been increased. With the help of statistical analysis, combined with analytical anthropological methods, the Forensic Anthropology Service of the Afranio Peixoto Medico-Legal Institute succeeded in identifying a charred body, with a margin of error of approximately 1:500 million to be obtained.

Experimental forensic scenes for the characterization of ground-penetrating radar wave response

Over the last few decades, the use of non-intrusive geophysical techniques, which allows for coverage of an entire crime scene in a reasonable amount of time, in forensic investigation has increased. In this study, we analyze the effectiveness of ground-penetrating radar (GPR) in forensics. Experimental scenes were simulated and some of the most commonly buried items in actual crime scenes were introduced, such as bone remains, guns and drug caches. Later, a GPR survey was conducted on the experimental grids with a 500 MHz antenna. The final purpose was to characterize the radar wave response expected for each set of remains to assist with its identification in later actual investigations. The results collected provided promising information that can be used when surveying real cases. Nevertheless, there were some interpretational difficulties regarding the sizes of the items and the electromagnetic properties of the materials. For these cases, finite-difference time-domain modeling was employed to achieve an advanced interpretation of the field data. The simulated models used were built from accurate geometric data provided by photogrammetric methods, which replicate the experimental scenes in fine detail. Furthermore, this approach allowed for the simulation of more realistic models, and the synthetic data obtained provided valuable information for assisting in the interpretation of field data. As a result of this work, it was concluded that GPR can be an effective tool when searching for a variety of materials during a crime scene investigation.
