Criminological and Medico-legal Aspects in Homicidal and Suicidal Sharp Force Fatalities

The interpretation of sharp force fatality dynamics may be difficult in some cases, but a contribution to analysis of the phenomenon may be provided by case studies. Therefore, the purpose of our study is focused on identifying, in observed sharp force fatalities, reliable parameters that can differentiate a homicidal and suicidal manner of death, with particular reference to criminological parameters. Data derived from sharp force fatality cases in Padua and Venice from 1997 to 2019, anonymized and collected in Excel, included personal, circumstantial, clinical, and psychopathological–criminological data, as well as crime scene investigation, necroscopic, and toxicological data. Statistical analyses were performed using chi-square and Wilcoxon rank-sum tests. Possible predictors of homicide were analyzed by logistic regression. Six parameters (bloodstains distant from the body, clothing lacerations, hesitation/defense wounds, number of injuries, and potential motives) were significantly different in the two groups (p < 0.05). An independent statistical association between potential motives explaining the crime (p < 0.001; OR 27.533) and homicide on multiple logistic regression analysis was highlighted. The absence of clothing lacerations was inversely related to homicide (p = 0.002, OR 0.092). To the best of our knowledge, this is one of very few Italian studies concerning the differential diagnosis between homicidal and suicidal sharp force fatalities. The dynamics of the event is established in most cases by the integrated evaluation of data from crime scene investigation and the autopsy. Nevertheless, in an atypical scenario, a psychopathological–criminological analysis may provide essential elements, and particular attention should be given to the identification of potential explanatory motives.     

Multi-Rater Agreement Using the Adapted Fracture Healing Scale (AFHS) for the Assessment of Tubular Bones on Conventional Radiographs: Preliminary Study*

Better understanding of the timing of fracture healing may help in cases of interpersonal violence but also of personal identification. The intra- and inter-rater agreement for the adapted fracture healing scale (AFHS) assessing the post-traumatic time interval on radiographs were tested. This is a preliminary study, providing essential information on method reliability for upcoming studies using the AFHS. Five raters (two radiologists, a forensic pathologist, an orthopedist, and an anthropologist) were presented with a test in three parts consisting of 85 radiographs (from 30 adults) of fractures of tubular bones in different stages of healing purposefully selected from more than 1500 radiographs. The raters were firstly asked to assess 15 features describing fracture healing as present, absent, or not assessable. Thereafter, the raters were asked to choose from the AFHS a single-stage best representing the observed healing pattern. The intra- and inter-rater agreement were assessed using single-rating, absolute agreement, two-way mixed-effects intra-class correlation (ICC) coefficients. The intra-rater ICC of radiologist 1 ranged from 0.80 to 0.94. The radiologists’ inter-rater ICC ranged from 0.68 to 0.74, while it ranged from −0.01 to 0.90 for the other raters. The good to excellent ICC among the radiologists and forensic anthropologist provides good foundation for the use of the AFHS in forensic cases of trauma dating. The poor to good results for the other physicians indicate that using the AFHS requires training in skeletal anatomy and radiology.

School predictors of alcohol use in high school Hispanic and non-Hispanic youth

Many youth alcohol prevention programs are not culturally sensitive and have focused on avoidance tactics. Given the differences in alcohol use and the possibly differing intervention strategies for Hispanic and non-Hispanic youth, this study aims to analyze the contributing factors of alcohol use within these two groups. Two hundred and one high school students participated in a survey. Findings indicate that prevention programs should focus on situational opportunities to use alcohol for both Hispanic and non-Hispanic youth. For Hispanic students, school management skills did not relate to less alcohol use, as expected. There should be less emphasis on how risky drinking can be, and more emphasis on the moral implications or “wrongness” of drinking, particularly for non-Hispanics. The discussion includes some possible interpretations of the relationship between skill management skills and heightened alcohol use for Hispanic students.     

Examination of the consistency of interviewer performance across three distinct interview contexts

Abstract

The current study examined the consistency of investigative interviewers' performance (n=31) across three distinct interview paradigms: (a) a mock interview where an adult actor played the role of a child recalling abuse, (b) a mock interview where a school child recalled an innocuous event that was staged at the child's school, and (c) a field interview where the interviewer elicited a statement of abuse from a child. Performance was measured by calculating the proportion of open-ended and leading questions, and by eliciting expert ratings of the presence of a range of problem behaviours commonly exhibited by interviewers. Overall, the performance of individual interviewers was relatively stable across the tasks. Heterogeneity in stability, however, differed according to the type of question and the nature of the event being examined. In particular, the mock interview paradigm where the adult acted the role of an alleged child abuse victim produced a measure of performance that was more similar to the field interview than the interview where a school child recalled an innocuous event. The implications of the findings for trainers, and directions for future research, are discussed.     

Applicability of Cranial Models in Urethane Resin and Foam as a Substitute for Bone: Are Synthetic Materials Reliable?

As literature is poor in functional synthetic cranial models, in this study, synthetic handmade models of cranial vaults were produced in two different materials (a urethane resin and a self‐hardening foam), from multiple bone specimens (eight original cranial vaults: four human and four swine), in order to test their resemblance to bone structure in behavior, during fracture formation. All the vaults were mechanically tested with a 2‐kg impact weight and filmed with a high‐speed camera. Fracture patterns were homogeneous in all swine vaults and heterogeneous in human vaults, with resin fractures more similar to bone fractures. Mean fracture latency time extrapolated by videos were of 0.75 msec (bone), 1.5 msec (resin), 5.12 msec (foam) for human vaults and of 0.625 msec (bone), 1.87 msec (resin), 3.75 msec (foam) for swine vaults. These data showed that resin models are more similar to bone than foam reproductions, but that synthetic material may behave quite differently from bone as concerns fracture latency times.     

The Impact of the Housing Bubble on the Growth of Municipal Debt: Evidence from Spain

The aim of this paper is to analyse the impact of the recent Spanish housing boom and the subsequent burst on local public finances. Particularly, we investigate the effect of the rise and later fall in revenue from urban development on local government debt. Using a sample of the Spanish largest municipalities in the period 2003–2011, we find that debt was substituted by revenue from urban development during boom years and this substitution effect vanished after the burst of the boom. Our results also reveal that local public finances have worsened after the burst of the housing bubble since now they have larger current spending and smaller savings.     

The Difficult Task of Assessing Perimortem and Postmortem Fractures on the Skeleton: A Blind Text on 210 Fractures of Known Origin

The distinction between perimortem and postmortem fractures is an important challenge for forensic anthropology. Such a crucial task is presently based on macro‐morphological criteria widely accepted in the scientific community. However, several limits affect these parameters which have not yet been investigated thoroughly. This study aims at highlighting the pitfalls and errors in evaluating perimortem or postmortem fractures. Two trained forensic anthropologists were asked to classify 210 fractures of known origin in four skeletons (three victims of blunt force trauma and one natural death) as perimortem, postmortem, or dubious, twice in 6 months in order to assess intraobserver error also. Results show large errors, ranging from 14.8 to 37% for perimortem fractures and from 5.5 to 14.8% for postmortem ones; more than 80% of errors concerned trabecular bone. This supports the need for more objective and reliable criteria for a correct assessment of peri‐ and postmortem bone fractures.     

Codes of conduct and practical recommendations as tools for self-regulation and soft regulation in EU public affairs

During the 2000s–2010s, EU Commission and Parliament and European interest groups advanced a specific model of regulation. It combines, on one side, lobbyists self-regulation—the codes of conduct for EU lobbying professionals' associations, such as SEAP and EPACA—with institutional nonbinding or “soft” regulation on the other side—the EU Transparency Register framework for registered interest groups, its code of conduct, the related system of checks, alerts, and complaints about interest groups misconduct put forward by the EU Joint Transparency Register Secretariat, the list of Dos and Don'ts by the EU Ombudsman. This paper examines the peculiar lobbying self-regulation and soft regulation tools and practices, as implemented within the EU model: SEAP and EPACA codes of conduct, EU Transparency Register, EU Interest Groups Code of Conduct, Commissioners and MPs codes of conduct, the procedures of the EU Joint Transparency Register Secretariat, and the Ombudsman list of Dos and Don'ts, underlining their growing impact on interest groups registration to the EU Transparency Register. This EU innovative regulatory model-based on a peculiar mix of self-regulation and institutional, incentive-based, soft regulation-stands as a concrete alternative to the traditional North American top-down binding regulatory pattern. The EU model is based on a participatory, cooperative, and pragmatic dialogue between European policy makers and interest groups. Clarifying the concept, the nature, and the functions of this model, while underlining its peculiarity is the purpose of this paper.
