Is the Expert Admissibility Game Fixed?: Judicial Gatekeeping of Fire and Arson Evidence

Anecdotal evidence claims that in criminal cases, trial judges admit the prosecution's expert witnesses more readily than the defendants', and in civil cases the reverse is true; judges exclude plaintiffs' experts more often than civil defendants' experts. This occurs despite the fact that, with few exceptions, the same rules of admissibility apply to all parties and, in most jurisdictions, across criminal and civil cases. This article empirically tests this differential by reviewing judicial decisions to admit or exclude evidence holding the type of expert testimony constant, fire and arson evidence, across criminal and civil cases in the United States. The study examines the admissibility of fire and arson investigation experts in criminal and civil cases across all legal parties in fifty‐seven federal and state opinions in the United States. The findings offer empirical support of a bias in criminal cases and in civil cases which present expert witnesses at trial, and is less pronounced, but still evident, on appeal. Specifically, the role of the party that offers the evidence has a profound effect on whether arson evidence is admitted, even when factors around the judge's political affiliation, attorney experience, expert qualifications, and rules of evidence are taken into account.     

The Use of CT Scans in Estimating Age at Death by Examining the Extent of Ectocranial Suture Closure

We examined the utility of CT scans in the evaluation of degree of ectocranial suture closure. Five cranial points (left and right midcoronal positions, left and right midlambdoidal positions, and the lambda) were evaluated in 231 CT scans using a three‐point scoring system (open, partial closed, and closed). The slice increment and thickness varied between three groups of the scans. The results showed a good correlation between degree of suture closure and increasing age in each group. Young individuals (<40 years) and old individuals (>60 years) could be clearly distinguished from the middle‐aged individuals. ANOVA test revealed no difference between two groups of scans and between left and right sides (p > 0.05). Interobserver agreement was good, especially considering the score by sides. The results of this study create the base for developing a robust and simple method to estimate the age at death using CT scans.     

Innovation and internationalization: the case of Italy

The aim of this paper is to analyze the impact of international activities on knowledge output. For this purpose, we employ a dataset containing exclusively qualitative information about a sample of small and medium Italian manufacturing firms. In the econometric analysis, a probit model is used. The results of the estimations highlight that firms active in international markets generate more knowledge than their counterparts which sell in the national market only. There are two possible explanations of this result. First, globally engaged firms employ more knowledge inputs, such as higher innovation expenditures. Second, international firms are more innovative because they can access to a larger flow of ideas from external sources.     

The Crime of Aggression before the House of Lords: Chronicle of a Death Foretold

In the days preceding the invasion of Iraq by the Coalitionforces, groups of individuals committed acts of civil disobediencein British military bases to hinder what they thought were unlawfulpreparations for an aggressive war. In R v. Jones et al., theHouse of Lords examined the question of whether individualscan rely upon the alleged prevention of crimes against peaceto justify otherwise unlawful actions under English law. TheLords ruled that the crime of aggression is a crime under customaryinternational law, yet not under English law. This followedfrom the principle that customary crimes cannot be incorporatedinto the English legal system without statutory enactment. Asa result, the appellants could not invoke the ‘Nurembergdefence’ to elude responsibility incurred under domesticlegislation.     

Quantitative Analysis of the Morphological Changes of the Pubic Symphyseal Face and the Auricular Surface and Implications for Age at Death Estimation

Age estimation methods are often based on the age‐related morphological changes of the auricular surface and the pubic bone. In this study, a mathematical approach to quantify these changes has been tested analyzing the curvature variation on 3D models from CT and laser scans. The sample consisted of the 24 Suchey–Brooks (SB) pubic bone casts, 19 auricular surfaces from the Buckberry and Chamberlain (BC) “recording kit” and 98 pelvic bones from the Terry Collection (Smithsonian Institution). Strong and moderate correlations between phases and curvature were found in SB casts (ρ 0.60–0.93) and BC “recording kit” (ρ 0.47–0.75), moderate and weak correlations in the Terry Collection bones (pubic bones: ρ 0.29–0.51, auricular surfaces: ρ 0.33–0.50) but associated with large individual variability and overlap of curvature values between adjacent decades. The new procedure, requiring no expert judgment from the operator, achieved similar correlations that can be found in the classic methods.
