Sex Assessment from the Sacral Base by Means of Image Processing

Abstract:  To help improve sex assessment from skeletal remains, the present study considers the diagnostic value of the sacral base (basis osseus sacri) based on its planar image and related metric data. For this purpose, 114 adult sacra of known sex and age from two early 20th century Italian populations were examined, the first from Bologna, northern Italy ( n  = 76), and the second from Sassari, Sardinia ( n  = 38). Digital photos of the sacral base were taken with each bone in a standardized orientation. Technical drawing software was used to trace its profile and to measure related dimensions (area, perimeter, and breadth of S1 and total breadth of the sacrum). The measurements were subjected to discriminant and classification function analyses. The sex prediction success of 93.2% for the Bolognese sample, 81.6% for the Sassarese sample, and 88.3% for the pooled sample indicates that the first sacral vertebra is a good character for sex determination.     

Child malnutrition and mortality in China and Vietnam in a comparative perspective

Under the traditional socialist central planning system, economic growth in China and Vietnam was unstable and not very satisfactory. Yet, both countries achieved a remarkable progress in the area of human development. Later, under the market socialist model, China and Vietnam achieved very high rates of GDP growth, and malnutrition declined significantly. Yet, income distribution and the provision of key public services deteriorated in both countries. Progress in reducing child mortality in China was relatively slow, before improving in the early 2000s. Although Vietnam is much poorer than China, and has been growing less fast, its record in this area was markedly better. We show that this apparent paradox is due mainly to the fact that the negative side-effects of market-oriented reforms have reached a more advanced and alarming stage in China than in Vietnam. Our results also suggest that an additional factor is constituted by a relatively better status of women in Vietnam with respect to China. However, we also warn that signs are emerging in Vietnam too, indicating that it is entering a stage of development where the social problems now evident in China are starting to manifest themselves on a large and worrying scale. Our policy conclusions advocate in favour of re-establishing (in a new form, compatible with the maintenance of the economic dynamism of the market socialist system) some positive features of the pre-reform socialist model, among which universal public provision of basic public services is paramount.

Spontaneous umbilical cord hematoma: an unusual cause of fetal mortality: a report of 3 cases and review of the literature

Spontaneous hematoma of the umbilical cord represents a rare cause of fetal morbidity and mortality and the outcome is poor in half of the cases. There are many risk factors, such as infections, morphologic anomalies, alterations of the vessel walls, prolapses, twisting and traction of the cord, but in many cases the causes remain unknown. We present 3 cases of umbilical cord hematoma which took place at the end of the pregnancy and were followed by perinatal death of the fetus. In the 3 cases, which were autopsied including macroscopical and histopathologic examination of the placenta and the umbilical cord, a cordonal pathology was present; in all cases, there were alterations of the vascular wall, and in the third case inflammatory vasculopathy was found. In all 3 cases, the cause of death was attributed to acute anoxia due to the cordonal hematoma.     

Median Voter Preferences,Central Bank Independence and Conservatism

This paper studies how the independence and theconservatism of a central bank relate to the structureand stability of the median voter preferences. This isdone by means of a model of endogenous delegationwhere an opportunistic policy maker chooses themonetary regime (independence and conservatism) tomaximise the welfare of the median voter. The resultsshow that a high degree of inflation aversion ofmonetary policy is not necessarily associated with ahigh degree of central bank independence. A high andstable degree of inflation aversion of society (i.e.of the median voter) may lead to establish a dependentcentral bank which is highly inflation averse. This suggests that the negativecorrelation between inflation and central bankindependence indices detected by several empiricalstudies may reflect a link between inflation and somedeep features of social preferences.     

Loss Aversion in Politics

We study loss aversion in elections by investigating a median voter model (full convergence in a two‐candidate election) and a model of partial divergence of policy proposals. First, we show a status quo bias, an endowment effect, and a moderating effect of policies. Second, we show the occurrence of “long‐term cycles” in policies with self‐supporting movements to the right or the left. Finally, we prove that younger societies should be more prone to change and less affected by the status quo bias than older ones.     

Positive,Normative and Functional Schools in Law and Economics

During its relatively short history, the law and economics movement has developed three distinct schools of thought. The first two schools of thought, often referred to as the Chicago or positive school and the Yale or normative school, developed almost concurrently. The functional school of law and economics, which developed subsequently, draws from public choice theory and the constitutional perspective of the Virginia school of economics to offer a third perspective which is neither fully positive nor fully normative. Various important methodological questions have accompanied the debate between these schools concerning the appropriate role of economic analysis in the institutional design of lawmaking and the limits of methods of evaluation of social preferences and aggregate welfare in policy analysis. These debates have contributed to the growing intellectual interest in the economic analysis of law.JEL Classification: K00, B0, B5, B25, B41     

Elderly sexual offenders: two unusual cases*

The aim of this case report is to describe two cases of sexual abuse by elderly subjects for which the Judge commissioned an expert psychiatric-forensic opinion. The elderly are generally believed to commit nonviolent crimes, whereas the two cases we observed feature forcible rape committed by elderly offenders, who showed no form of mental disease and had rationally planned their offense. They had never previously committed similar acts and had no history of homosexuality; both had been married for many years before the death of their wives and had adult children. Finally, no previous episodes of rape emerged in their personal histories during interrogations. The sociocultural context in which the crimes were committed was identical and arouses interest as regards both the method employed and how the crimes were discovered. The legal authorities then commissioned accurate investigations including medicolegal and psychiatric-forensic evaluations of the offenders and their victims.
