SEM/EDS analysis and characterization of gunshot residues from Brazilian lead-free ammunition

The exposition to heavy metal-rich airborne due to fire practicing has forced to the development of heavy metal-free environmental ammunition primers all over the world. Here we characterize the GSR elements present in the Brazilian lead-free ammunition produced by Companhia Brasileira de Cartuchos (CBC) and commercialized by MagTech in the U.S. and Europe under the name CleanRange centerfire cartridges. Both first and second generations of CleanRange in calibers 9 mm Luger, .40 S&W, .380 AUTO and .38 SPL were analyzed and compared to regular Brazilian CBC ammunition by scanning electron microscopy/energy dispersive spectroscopy. Differences in composition and morphology of GSR particles from the two generations of CleanRange were observed. The first generation ammunition (found in Europe) presented spherical particles, being strontium the only unique element detected. The second generation (found in the U.S.) produced irregular particles composed mostly by potassium, aluminum, silicon and calcium. We can conclude that identification of GSR derived from CBC second generation lead-free ammunition in suspects' hands may be impossible without the addition of a distinct metallic taggant in the primer composition by the manufacturer.     

The calculus of voting: An empirical test

Abstract. According to the rational choice model, the calculus of voting takes the form of the equation R = BP − C, where the net rewards for voting (R) are a function of the instrumental benefits from the preferred outcome compared to others (B) and the probability (P) of casting the decisive vote that secures these benefits, minus the costs of becoming informed and going to the polls (C). Here, we provide a systematic test of this model. The analysis relies on two surveys, conducted during the 1995 Quebec referendum and the 1996 British Columbia provincial election, in which very specific questions measured each element of the model. As well, this study incorporates two other factors that can affect the propensity to vote — Respondents' level of political interest and their sense of duty. We find that B, P, and C each matter, but only among those with a relatively weak sense of duty. The feeling that one has a moral obligation to vote is the most powerful motivation to go to the polls. We conclude that the rational choice model is useful, but only in explaining behaviour at the margins of this important norm.     

Cerebral traumatism with a playground rocking toy mimicking shaken baby syndrome

Shaken baby syndrome (SBS), one of the most deadly and devastating forms of child abuse, is caused by violent shaking. The combination of subdural hematoma, retinal hemorrhage, brain swelling, and diffuse axonal injury is highly typical of this syndrome and faced with these autopsy findings, induced traumatic lesions are strongly considered. However, it is known that motor-vehicle accidents and falls from great height can also produce this pattern of injury. Nevertheless, stories of arms fall, couch fall, or bumped head while the baby is being carried are generally considered incompatible with SBS. We here report a case of a 2-year-old boy presenting with all the classic autopsy findings of SBS from a playground rocking toy shaken by an older child.     

From corruption to extortion: Conceptualization of post-communist corruption

Moral outrage and lack of comparison distorts the understanding of the natureand politically determined functions of governmental corruption in post-communist transition. As post-communist societies move towards open market systems and corruption is no longer limited to the public sector, politics is transformed into a potent tool for illegal transactions. The political structureitself creates corrupt practices that become a structural feature of transition societies. This article offers first a critical discussion of both moral theories of corruption and the thesis that posits a link between corruption and democracy deficit in post-communist countries. Subsequently, it sketches a neo-functionalist approach that puts corruption in a specific social context.With respect to East/Central Europe, corruption is presented as a betrayal ofpublic trust that serves specific requirements of an emerging ``extortioniststate.' These requirements relate to the expansion of extortion opportunitiesand their institutionalization into a semblance of a Tule of law system.     

Common Wealth

After reviewing developments in human rights law and international law – in particular the domestication of international human rights law and the rise of the democratic norm in international law – the importance of these developments for the Commonwealth and for its member states is highlighted and linked to many of the programmes and policies that the Commonwealth Secretariat has recently launched. This paper discusses these developments and others in order to stress the wealth of potential advantages for Commonwealth member states and their citizens that flow from a common commitment under the rule of law to human rights and democracy. The authors endeavour to show that such wealth is more than mere economic benefit – as important as that undoubtedly is – and that citizens stand to reap a moral system of government, one which expands the opportunities for popular participation in political processes and puts an end to social practices that marginalise some citizens and empower others.     

Scientific Research on the Efficiency of Public Expenditures: How and Where is it Going?

ABSTRACT

Recent scientific research has advanced the measurement of the relative performance of organizations and the efficiency of public spending, based on analyzes of the services offered and results achieved. However, from the methodological point of view, there are several methods to analyze the performance and efficiency of spending in the private and public sectors. In this sense, the present study performs a systematic bibliometric review to analyze all scientific publications on the efficiency of public spending published in the last 20 years. The results show that most cost-efficiency analyzes have been limited to education and health expenditures and have used quantitative analysis, mainly through the application of data-involution analysis. The present review is a first step in mapping scientific publications on efficiency in public spending, which will support researchers and managers to make public spending more efficient.
