Chemistry in crime investigation: sodium percarbonate effects on bloodstains detection

Chemistry plays a leading role in crime investigation. In the study of bloodstains, chemical reactions provide the means for the detection. All these procedures have been thoroughly studied. However, recently, a new source of error has been found: washing stains with "active oxygen" detergents abrogates presumptive and human hemoglobin tests for bloodstains (although visible). The aim of this investigation was to evaluate the ability of pure sodium percarbonate-main component of detergents-to abrogate presumptive and human hemoglobin tests. Then, a solution to this problem could be found. The results demonstrate that pure sodium percarbonate-itself-is able to abrogate all tests, as well as the different degrees to which each of them is affected by the product. Consequently, faced with a stain of bloody appearance, even the preliminary tests are negative; it is advisable to analyze the DNA. Otherwise, the opportunity of obtaining valuable information is lost.     

Chinese Economic Statecraft and U.S. Hegemony in Latin America: An Empirical Analysis, 2003–2014

If one interprets China's sizable rise in Latin America as an unprecedented phenomenon, it follows that the concurrent story of declining U.S. influence in the region is an event hastily acknowledged at best and ignored at worst. In this article, we ask whether Chinese economic statecraft in Latin America is related to the declining U.S. hegemonic influence in the region and explore how. To do so we analyze foreign direct investments, bank loans, and international trade from 2003 to 2014, when China became a major player in the region. We use data from 21 Latin American countries, and find that an inversely proportional relationship exists between the investments made by Chinese state‐owned enterprises (SOEs), bank loans, manufacturing exports, and the U.S. hegemonic influence exerted in the region. In other words, Beijing has filled the void left by a diminished U.S. presence in the latter's own backyard.     

A Natural Experiment in Political Decentralization: Local Institutions and Citizens' Political Engagement in Uruguay

The potential democratizing effect of political decentralization reforms has been a matter of substantial theoretical and empirical debate. This article analyzes the effect of local democratic institution building on the political attitudes and behavior of citizens living in small towns in Uruguay. More specifically, using a natural experiment design, this research seeks to establish the causal impact of recently established elections of local authorities on individuals' political engagement. It develops a comparative case study analyzing the consequences of this institutional innovation in two towns. It shows that individuals from the town where citizens have the opportunity to elect their local authorities have more positive attitudes toward politics than those from the town without such elections.

New Paths: Globalization in Historical Perspective

This essay argues that the historical–structural framework of analysis is still useful to describe the transformations generated by globalization in the underdeveloped countries, provided that it is employed with the subtlety needed to avoid reductionism. Globalization, in the same way as dependency, is nothing more than an unfolding of the capitalist system in today's historical conditions. The structural starting point conditions—but does not determine—the shape taken by economic and political processes. Political strategies for integrating into the global economy have a certain margin of autonomy. Still, the range of feasible strategies depends on factors that differ from country to country, such as the local capacity of income accumulation, the presence of foreign direct investment, the mix between nationally controlled production and production controlled by multinationals, the participation of the public sector in production, the capacity of the leadership, the prevailing ideologies, and so forth. In other words, there are alternative paths.     

Common law country update on international humanitarian law: annual update on national legislation, 2010

The article highlights the challenge before the courts to the decision of the parliamentary select committee to remove the former Chief Justice of Sri Lanka in January 2013. Parliament and the President proceeded with the impeachment and removal of the Chief Justice, despite court decisions, on the basis that this was a power specifically granted to the parliament under the constitution. The article examines how the legitimacy of impeachment proceedings of superior court judges can be ensured within the concept of the separation of powers without adversely impacting on the independence of the judiciary and the rule of law.     

Suicide by band saw

Suicidal injuries caused by power tools have rarely been reported in the literature. The case of a 37-year-old white male schizophrenic patient who sustained a fatal self-inflicted neck injury from a band saw, while engaging in occupational therapy, is presented. Unusual features of this type of injury as noted at postmortem examination were the extent of the wound, the absence of hesitation injuries, and the presence of grease wipe, bone dust, and sawdust within the wound.     

Thoughts about a model of constitutional articulation of the public power in the field of biomedical sciences]

This article analyses from a substantive and organizational point of view the current scope of competence of the Spanish public powers in the field of biomedical sciences. The general rule is established whereby the competence belongs to the State. The autonomous communities opt for silence, except for exceptional cases (Cantabria, Catalu?a, Madrid). Given this situation coupled with the lack of rulings by the Consitutional Tribunal on the possible conflicts that could arise between an autonomous community and the State in the field of biomedical sciences, Profesor Fonseca correctly concludes that there is a need to draft an express distribution of competences between the different public powers in this matter.
