Statistical analysis of DNA mixtures using peak area information and allelic drop out

A case of a woman killed in Perugia is reported. The woman was beaten to death and the body showed evidence of bites, kicks and punches. The request of the Court was to verify the presence of bites and if they belonged to humans. Morphological examination and genetic analysis with human Y-specific markers were performed in order to verify the origin of the bites. The DNA profile from the surrounded area of the traces was compared with the profile of the victim's husband (the suspect).The results showed a match between the profile of the suspect and that of the traces for all loci examined. Due to the fact that also other relatives of the husband's male lineage lived in the same house, it was not possible to identify the man who really contributed to the traces. Therefore, the analysis was implemented with autosomal STR markers, which showed a mixed genetic profile. In order to verify the number and the identity of the contributors, statistical analysis based upon peak area information was performed with Probabilistic Expert Systems.     

Mental disorder is a cause of crime: The cornerstone of forensic psychiatry

The assumption that mental disorder is a cause of crime is the foundation of forensic psychiatry, but conceptual, epistemological, and empirical analyses show that neither mental nor crime, or the causation implied, are clear-cut concepts. “Mental” denotes heterogeneous aspects of a person such as inner experiences, cognitive abilities, and behaviour patterns described in a non-physical vocabulary. In psychology and psychiatry, mental describes law-bound, caused aspects of human functioning that are predictable and generalizable. Problems defined as mental disorders are end-points of dimensional inter-individual differences rather than natural categories. Deficits in cognitive faculties, such as attention, verbal understanding, impulse control, and reality assessment, may be susceptibility factors that relate to behaviours (such as crimes) by increasing the probability (risk) for a negative behaviour or constitute causes in the sense of INUS conditions (Insufficient but Non-redundant parts of Unnecessary but Sufficient conditions). Attributing causes to complex behaviours such as crimes is not an unbiased process, and mental disorders will attract disproportionate attention when it comes to explanations of behaviours that we wish to distance ourselves from. Only by rigorous interpretation of what psychiatry actually can inform us about, using empirical analyses of quantified aggressive antisocial behaviours and their possible explanatory factors, can we gain a clearer notion of the relationship between mental disorder and crime.     

Retracing One’s Steps: Searching for the Ethics of Legal Interpretation

The article discusses the problem of interpretation in law. Are there some criteria by which we can distinguish a good interpretation from a bad one, interpretation from over-interpretation? It is argued in this article that there is always a choice in defining the meaning of a text and this choice can be seen as an ethical one. This article thus studies the question of limits of interpretation by focusing on the ethical elements of interpretation. It is argued here that legal interpretation contains a requirement of justice that shapes the responsibility that the interpreter carries for his choices of meaning. Therefore the ethical elements of interpretation are especially pressing in the interpretation of legal texts.     

Centralization of school finance in Michigan

School finance reform in Michigan involved centralization (at the state level) of spending decisions about schools, a large tax shift (mostly from property to sales), and a small tax cut. The changes came about after two decades of failed attempts to reduce property taxes in the state, and were the immediate result of an unlikely piece of legislation that abolished all funding for public schools. Unlike most centralized systems, foundation grants in Michigan differ by district. Distributionally, the reforms favor residents of small, rural districts (whose spending was increased sharply). Residents of poorer urban areas, including Detroit, lost net income as a result of the reforms, as did residents of some of the richest suburbs in the state. Michigan permits a number of districts to supplement their foundation grants by limited amounts, a strategy that we argue may be a promising way of combining the efficiency benefits of local control with the equity benefits of foundation grant systems.     

Forests lost and found in tropical Latin America: the woodland ‘green revolution’

Forest dynamics in the Latin American tropics now take directions that no one would have predicted a decade ago. Deforestation in the Brazilian Amazon has dropped by over 80 percent, a pattern mimicked elsewhere in Amazonia, and is down by more than a third in Central America. Forest resurgence – increasing forest cover in inhabited landscapes or abandoned lands – is also expanding. In Latin America, woodland cover is increasing, at least for now, more than it is being lost. These dramatic shifts suggest quite profound and rapid transformations of agrarian worlds, and imply that previous models of understanding small-farmer dynamics merit significant review centering less on field agriculture and more on emergent forest regimes, and in many ways a new, increasingly globalized economic and policy landscape that emphasizes woodlands.

This paper analyzes changing deforestation drivers and the implications of forest recovery and wooded landscapes emerging through social pressure, social policy, new government agencies, governance, institutions, ideologies, markets, migration and ‘neo-liberalization’ of nature. These changes include an expanded, but still constrained, arena for new social movements and civil society. These point to significant structural changes, changes in tropical natures, and require reframing of the ‘peasant question’ and the functions of rurality in the twenty-first century in light of forest dynamics.     

Testing a Financial Incentive to Promote Re‐employment among Displaced Workers: The Canadian Earnings Supplement Project (ESP)

This article presents findings from a randomized experiment conducted in four Canadian provinces to measure the effects of a generous financial incentive that was designed to promote rapid re‐employment among workers who were displaced from their jobs by changing economic conditions. The incentive tested was an earnings supplement which, for as long as 2 years and as much as $250 weekly, would replace 75 percent of the earnings loss incurred by displaced workers who took a new lower‐paying full‐time job within six months of receiving a supplement offer. Findings from the experiment indicate that although persons offered the supplement understood its terms and conditions, only 2 out of 10 actually received supplement payments. Furthermore, the supplement offer had little effect on job‐search behavior, employment prospects, or receipt of unemployment insurance. Nevertheless, persons who received supplement payments benefited from them substantially. On average, they received payments for 64 weeks, totaling $8,705. © 2001 by the Association for Public Policy Analysis and Management.     

Religious Rage: A Quantitative Analysis of the Intensity of Religious Conflicts

ABSTRACT

The conventional wisdom that religious conflicts are more intense than other types of conflicts is tested in this study using a cross-sectional time series analysis. The statistical test evaluates the intensity of 278 territorial conflict phases in the International Peace Research Institute in Oslo, Norway (PRIO) Armed Conflict Dataset. The results indicate support for the assumption that religious conflicts are more intense than other types of conflicts; however, the relationship disappears when the relevance of religion is taken into account. Furthermore, this study evaluates the relationship of conflict intensity with the type of religion involved in the conflict and determines that no religion exhibits a significantly higher or lower intensity than the others.     

Televised Exposure to Politics: New Measures for a Fragmented Media Environment

For many research purposes, scholars need reliable and valid survey measures of the extent to which people have been exposed to various kinds of political content in mass media. Nonetheless, good measures of media exposure, and of exposure to political television in particular, have proven elusive. Increasingly fragmented audiences for political television have only made this problem more severe. To address these concerns, we propose a new way of measuring exposure to political television and evaluate its reliability and predictive validity using three waves of nationally representative panel data collected during the 2008 presidential campaign. We find that people can reliably report the specific television programs they watch regularly, and that these measures predict change over time in knowledge of candidate issue positions, a much higher standard of predictive validity than any other measure has met to date.
