Implant Bone Integration Importance in Forensic Identification

Odontological identification consists of the comparison of antemortem dental information regarding a missing person with postmortem data from an unidentified corpse or human remains. Usually, the comparison concerns morphologic features that the operator chooses among all the visible characteristics because of inter‐individual uniqueness; for this reason, implants can be of enormous assistance. A case concerning the recovery of a burnt oral implant, connected to a bone fragment, among 2780 charred bone fragments, suspected to have belonged to a victim of homicide, is presented to demonstrate that dental implants and their site of bone integration represent a very precious element for personal forensic identification. Because of their morphological invariability in time and because of their morphologic uniqueness, they were used as evidence to associate unidentified human charred remains to a missing person where DNA analysis failed to do so. The case illustrates the fundamental contribution, not yet described in literature, given by the clinical aspects of tooth replacement with dental implants to a forensic discipline. Clinical practitioners should therefore be aware of the great importance of their work and of dental records in a forensic identification scenario.     

Lawyers' Perceptions of the U.S. Supreme Court: Is the Court a “Political” Institution?

Do legal elites—lawyers admitted to federal appellate bars—perceive the Supreme Court as a “political” institution? Legal elites differentiate themselves from the mass public in the amount and sources of information about the Court. They also hold near‐universal perceptions of Court legitimacy, a result we use to derive competing theoretical expectations regarding the impact of ideological disagreement on various Court perceptions. Survey data show that many legal elites perceive the Court as political in its decision making, while a minority perceive the Court as activist and influenced by external political forces. Ideological disagreement with the Court's outputs significantly elevates political perceptions of decision making, while it exhibits a null and moderate impact on perceptions of activism and external political influence, respectively. To justify negative affect derived from ideological disagreement, elites highlight the political aspects of the Court's decision making rather than engage in “global delegitimization” of the institution itself.     

The Erratic Behavior of Lesions in Burnt Bone

This study analyses depressed fractures (by blunt force trauma) and circular full‐thickness injuries (drill injuries and gunshot wounds) in charred bones. Fifty bovine ribs (total 104 lesions) were divided into three groups. The first group consisted in 20 depressed hammer‐produced fractures; in the second one, 60 round drill‐holes were produced (30 circular, 30 semicircular); in the third group, 12 fleshed and 12 skeletonized ribs were hit by 9‐mm bullets. Each specimen was carbonized in an electric oven up to 800°C. Morphological and metric analyses were performed before and after: morphological features were preserved, but depressed fractures showed an increase in their dimensions (p‐value < 0.05); the drilled holes shrunk (p‐value < 0.01); the charring cycle increased the number of fractures in samples with gunshot wounds differently in fleshed and defleshed ribs. This study showed the complex behavior of charred bone, for what concerns the interpretation of trauma and how caution should be applied.     

The Application of Flow Cytometry as a Rapid and Sensitive Screening Method to Detect Contamination of Vitreous Humor Samples and Avoid Miscalculation of the Postmortem Interval

Research into maximizing the speed, precision, and reliability of estimating the postmortem interval (PMI) has been a recurring object of investigation and methodologies based on the vitreous humor (VH) have provided good results. However, contamination from causes not readily apparent, such as blood, can occur, and thus lead not only to an erroneous estimation of PMI, but also interfere with the correct identification of other substances in the VH. We have developed a flow cytometry method which quantifies blood contamination and is able to detect erythrocytes in 1:750,000 dilution of contaminated VH which affects the results of hypoxanthine. It is an improvement on the previous more complex mass spectrometry method, being faster, more sensitive, and readily available. As such, it could be proposed for the rapid screening of appropriate samples by detecting and eliminating blood contaminated samples from PMI estimation.     

Corruption and Political Culture in America: An Empirical Perspective

Political culture helps define the boundaries of permissiblepolitical action. Thus, it should affect the amounts and typesof political corruption occurring in political systems, as wellas responses to corruption when it is discovered. This articlecompares the distribution of corruption convictions among federaljudicial districts over a three-year period to social and politicalcharacteristics of the districts, and to scaled measures ofElazar's moralistic, individualistic, and traditionalistic politicalsubcultures. Nationally, strong moralistic subcultures and highvoter turnouts are associated with numerous convictions, bothbefore and after district population is controlled. Analysisof regional patterns reveals a different model in the South,however, one suggesting ideas about the dynamics of traditionalisticpolitics. Corruption, and the impact of federal laws againstit, are best understood within their political and culturalsettings. ^* I am indebted to George Calafut and Philip Sidel of the SocialScience Computer Research Institute, University of Pittsburgh,who gave me many hours of assistance in assembling data.

Spatial continuity and individual variability: A review of recent work on the geography of electoral change

Analyses have shown that the results of a series of general elections display considerable stability in the geography of voting patterns over time. Further, it has been suggested that the change between two electrons is similar in all places. This paper challenges the latter findings, using data from Great Britain and New Zealand. It is shown that even if there were a pattern of uniform swing, this would be produced by spatial variations in voter transition matrices. A review of analyses of those variations suggests the important roles of the neighbourhood effect, campaign spending, tactical voting, sectional effects, and migration as influences on voter behaviour.
