Contribution for an African autosomic STR database (AmpF/STR Identifiler and Powerplex 16 System) and a report on genotypic variations

Allele frequencies, together with some parameters of forensic interest, for 17 STRs included in the AmpF/STR Identifiler (CSF1PO, D2S1338, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D19S433, D21S11, FGA, TH01, TPO and VWA) and Powerplex 16 System (CSF1PO, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, FGA, Penta D, Penta E, TH01, TPO and VWA) were estimated from a sample of 135-144 unrelated individuals from Mozambique. No deviations from Hardy-Weinberg equilibrium were observed with the exception of the FGA locus (using the Bonferroni correction for the number of loci analysed, the departure observed at this locus was not significant). Comparative analyses between our population data and other African databases, namely Promega's African-Americans, AB Applied Biosystems African-Americans and two other population samples from Mozambique and Guiné Bissau, are presented and discussed. Genotype inconsistencies between both commercial kits (for D16S539 and D8S1179) and other genotypic variations (three-banded allele patterns for TPO) are also reported.     

Is transparency an effective anti-corruption strategy? Evidence from a field experiment in India

Can freedom of information laws be harnessed by underprivileged members of society and used to obtain greater access to basic public goods that are otherwise attainable only through bribery? Drawing on a field experiment on access to ration cards among New Delhi's slum dwellers, we demonstrate that India's recently adopted freedom of information law is almost as effective as bribery in helping the poor to secure access to a basic public service. We find support for the theoretical proposition that greater transparency and voice lowers corruption even in highly hierarchical and unequal societies.     

Analysis of the Effect of Cyclophosphamide and Methotrexate on Chrysomya megacephala (Diptera: Calliphoridae),

Forensic entomotoxicology investigates the effects of chemical substances in the development of scavenger insects and the reflection on estimating the minimum postmortem interval (PMI). To evaluate the impact of the chemotherapeutic drugs cyclophosphamide (CF) and methotrexate (MTX) on the postembryonic development of Chrysomya megacephala, controlled experiments were performed by rearing the larvae on spiked minced beef with different concentrations of these drugs. The results indicated that CF significantly decreased their developmental rate up to 28 h but had no significant effect on larval and adult sizes, survival rate, and sex ratio, whereas MTX decreased larval and adult sizes, survival rate, and there was a deviation in the expected sex ratio toward females in MTX‐exposed larvae but had no significant impact on developmental rate. These negative interference factors should be considered in cases of suspected death of people that have undergone chemotherapy.     

Economic crisis and lawmaking. The impact of crisis on legislative agenda in Italy

Major economic crises are focal events that often drive changes in various aspects of political systems. Although extensive work has been done to investigate the effect of exogenous shocks on political phenomena such as government termination, public opinion and policy outcomes, the impact of major crises on the process of policymaking has so far received scarce attention. Building on existing literature on policy agendas and legislative organization, this paper explores how the Eurozone crisis has affected the legislative agenda of the Italian parliament. The data used include information on the 1,110 bills submitted to parliament during Legislature XVI (2008–2013). Our analysis shows that, with the worsening of the crisis, bill proposals related to macroeconomic issues become increasingly more likely to enter the legislative agenda, displacing legislation dealing with other topics. Our argument is corroborated by a comparison between Legislature XVI and a pre-crisis legislature (2001–2006), as in the latter term the legislative agenda follows different patterns.     

A Novel Method for Removing a Spinal Cord with Attached Cervical Ganglia from a Pediatric Decedent

A diagnosis of child abuse is dependent on a comprehensive and accurate assessment of injury in the context of a thorough investigation. However, signatures of trauma are often subtle and interpretation can be very difficult. Recently, researchers have refocused their attention from the head to the neck in search of traumatic signatures of abusive head trauma. HCIFS has developed a technique to remove the cervical spinal cord with the ganglia attached that is less destructive and more time and cost efficient than alternative methods previously published. Once removed, the dorsal nerve roots and ganglia are evaluated for the presence of hemorrhage. The authors performed a small pilot study using the novel method to evaluate 20 decedents with a history of blunt force trauma and eight without a traumatic history. Fifteen of the traumatic deaths and two of the nontraumatic deaths were found to have dorsal nerve root and/or ganglia hemorrhage.     

Building Support for the Asad Regime: The Syrian Diaspora in Argentina and Brazil and the Syrian Uprising

ABSTRACT

Brazil and Argentina are hosts to two of the largest populations of Syrian descent in Latin America. While Syrian immigrants and their descendants have usually defined their identities based on broad Arab nationalistic references, creating and affiliating themselves to Syrian-Lebanese and/or Arab institutions, the ongoing civil war in Syria has triggered an unprecedented mobilization around specifically Syrian issues. Most diasporic organizations have shown an unconditional support for the Ba?thist regime. This article aims at understanding the political mobilization of the Syrian diaspora in Argentina and Brazil, as well as unveiling how Bashar al-Asad's government has tried to build on their support.     

Fatal hemorrhage from a periumbilical wound: Stabbing or hemorrhage from a caput medusae?

Varices are the main clinical manifestation of portal hypertension, and their bleeding is the predominant cause of mortality from this condition. Periumbilical varices are known as “caput medusae.” Reports of their bleeding are rare, with only three fatal cases described in the literature. The antemortem diagnosis is relatively simple, while the postmortem diagnosis is more complex. This paper is the first report of fatal hemorrhage from a caput medusae for which the diagnosis was made postmortem, thanks to a complete diagnostic process including scene and circumstances, medical history, and autopsy with detailed histology. The circumstantial analysis showed the presence of a large amount of blood at the scene, blood which originated from a small abdominal wound; an analysis of the subject's clinical data reported that he was affected by portal hypertension. The autopsy revealed some dilated and convoluted veins in the subcutaneous tissue of the umbilical region; a fistula between these veins and the abdominal wound was detected. The histological study confirmed the presence of periumbilical varices, one of them ruptured and connected with the overlying skin. The cause of death was attributed to a massive hemorrhage generated by a periumbilical varix in a patient affected by portal hypertension.     

Analysis of histomorphometric variables: Proposal and validation of osteon definitions

Histological analysis of bone tissue has been used to explore a variety of questions relating to age-at-death, habitual behaviors, health, and nutritional stress. Identification of intact and fragmentary osteons is of key interest to many researchers in these studies, yet the definitions of these features vary between researchers making cross-study comparisons problematic. Furthermore, histological variable definitions are often ambiguous or require subjective classifications by the observer. As a result, and as indicated by previous studies, observer error and misclassification of certain variables, namely intact and fragmentary osteons, can be significant. This study proposes new definitions for intact and fragmentary osteons that are designed to limit observer subjectivity and also explore efficacy of combining osteon types into one variable. A sample of 30 6th rib cross-sections from a modern forensic population was used to test the validity of the proposed definitions. Observations of intact osteon population density (OPD(I)) and fragmentary osteon population density (OPD(F)) were made by three observers for each cross-section. These observations were used to explore the interobserver error associated with the proposed definitions and determine if combining variables into one variable (OPD) mitigates persisting classification difficulties. Results indicate that the proposed definitions significantly reduce interobserver error and misclassification of intact and fragmentary osteons. However, the interobserver error associated with fragmentary osteons is still high. Evaluation of the variables independently indicates that combining variables has potential to reduce the predictive strength of an age estimation model and the ability to interpret age-related bone remodeling.     

Self‐Strangulation Through A Sphygmomanometer: An Uncommon Suicide

Suicide by asphyxia is quite a common event in forensic practice and may be implemented in different ways. The authors report a unique case of a 16‐year‐old youth who committed suicide by means of a standard mercury sphygmomanometer. This manner of suicide has never been described in the literature reviewed. A complete forensic investigation led to the conclusion that the cause of death was mechanical asphyxia, ascribed to self‐strangulation by means of an atypical item. The victim suffered from attention‐deficit/hyperactivity disorder (ADHD) syndrome and was assisted by support teachers. He had a solitary and depressive personality. The exceptional nature of this case suggests that sphygmomanometers may be regarded as possible means of self‐strangulation. The case also highlights the importance of managing patients with psychiatric or cognitive disorders; indeed, particular caution is required to keep them away from objects that, although apparently harmless, can become lethal.
