Characterization of children's latent fingerprint residues by infrared microspectroscopy: forensic implications

The chemistry of children's latent fingerprint residues was investigated as a function of time and temperature by non-destructive spectrochemical analysis. Latent fingerprints from children, ranging in age from 2 to 11 years, were deposited onto aluminum-coated glass slides and were analyzed by Fourier-Transform Infrared Microspectroscopy. The results revealed that there are three major classes of compounds present in children's latent fingerprints: carboxylic acid salts, proteins, and esters. By studying the changes in the fingerprint residues as a function of time and at elevated temperatures, we discovered that the salts in the fingerprint residues are stable relative to the esters. These findings have relevant forensic implications; by targeting the acid salts instead of the esters or proteins, children's latent fingerprints may be recovered after extended periods of time have elapsed.     

Postmortem detection of isopropanol in ketoacidosis

Isopropanol (IPA) detected in deaths because of diabetic ketoacidosis (DKA) or alcoholic ketoacidosis (AKA) may cause concern for IPA poisoning. This study addressed this concern in a 15-year retrospective review of 260 deaths in which concentrations of acetone and IPA, as well as their ratios, were compared in DKA (175 cases), AKA (79 cases), and IPA intoxication (six cases). The results demonstrated the frequency of detecting IPA in ketoacidosis when there was no evidence of IPA ingestion. IPA was detectable in 77% of DKA cases with quantifiable concentrations averaging 15.1 ± 13.0 mg/dL; 52% of AKA cases with quantifiable concentrations averaging 18.5 ± 22.1 mg/dL; and in cases of IPA intoxication, averaging 326 ± 260 mg/dL. There was weak correlation of IPA production with postmortem interval in DKA only (r = -0.48). Although IPA concentrations were much higher with ingestion, potentially toxic concentrations were achievable in DKA without known ingestion.     

Differentiating Between Genuine Damage and Falsified Damage to a Garment Following an Alleged Sexual Assault*

Abstract: An allegation of sexual assault was made in which a bra was torn off by the assailant causing extensive damage; however, it was observed that the hook and eye fastening was still intact. It was felt that it was not possible for a garment to receive such damage without damage to the hook and eye fastening, thus indicating that the complainant caused the damage to the bra herself to support a false allegation. Reconstruction experiments were conducted in which the conditions of the allegation were simulated utilizing a range of similar bras. Following the infliction of damage, the hook and eye fastenings were examined. In eight of nine experiments, the hook and eye fastening were intact, despite the application of enough force to cause separation of the bra cups in five of the experiments. This shows that bras may suffer extensive damage without damage to the hook and eye fastening.     

Donation of 'spare' fresh or frozen embryos to research: who decides that an embryo is 'spare' and how can we enhance the quality and protect the validity of consent?

This paper analyses elements of the legal process of consent to the donation of 'spare' embryos to research, including stem-cell research, and makes a recommendation intended to enhance the quality of that process, including on occasion by guarding against the invalidity of such consent. This is important in its own right and also so as to maximise the reproductive treatment options of couples engaged in in vitro fertilisation (IVF) treatment and to avoid possible harms to them. In Part 1, with reference to qualitative data from three UK IVF clinics, we explore the often delicate and contingent nature of what comes to be, for legal purposes, a 'spare' embryo. The way in which an embryo becomes 'spare', with its implications for the process of consent to donation to research, is not addressed in the relevant reports relating to or codes of practice governing the donation of embryos to research, which assume an unproblematic notion of the 'spare' embryo. Significantly, our analysis demonstrates that there is an important and previously unrecognised first stage in the donation of a 'spare' embryo to research, namely: consent to an embryo being 'spare' and so, at the same time, to its disuse in treatment. This is not explicitly covered by the Human Fertilisation and Embryology (HFE) Act 1990, as amended by the HFE Act 2008. Having identified this important initial stage in the process of consent to the donation of a 'spare' embryo to research in conclusion to Part 1, in Part 2 we analyse the idea of consent to an embryo's disuse in treatment on the basis that it is 'spare' with reference to the legal elements of consent, namely information as to nature and purpose, capacity, and voluntariness. We argue that there are in fact three related consent processes in play, of which the principal one concerns consent to an embryo's disuse in treatment. If the quality of this first consent is compromised, in turn this will impact on the quality of the consent to the donation of that 'spare' embryo to research, followed by the quality of consent to future cycles of assisted reproduction treatment in the event that these are needed as a result of a donation decision. The analysis overall is of central relevance to the debate as to whether, and if so when, it should be permissible to request the donation of fresh embryos for research, as opposed to those that have been frozen and, for instance, have reached the end of their statutory storage term. This has a particular bearing on the donation of embryos to stem-cell research since there is a debate as to whether fresh embryos are most useful for this.     

Family violence risk assessment: A predictive cross-validation study of the Domestic Violence Screening Instrument-Revised (DVSI-R)

This research was a cross-validation study of the Domestic Violence Screening Instrument-Revised (DVSI-R), using a diverse, statewide sample of 3,569 family violence perpetrators in Connecticut, assessed in February and March of 2007. It analyzed re-arrest data collected during an 18-month period post assessment. Three issues were central, which have been ignored in previous research on family violence risk assessment: (1) analyzing five refined measures of behavioral recidivism, (2) determining whether perpetrator characteristics and types of family and household relationships (beyond just heterosexual intimate partners) moderate the empirical relations between the DVSI-R and the behavioral recidivism measures, and (3) determining whether structured clinical judgment about the imminent risk of future violence to the victim or to others corresponds with recidivism predicted by the DVSI-R total numeric risk scores. The empirical findings showed that the DVSI-R had significant predictive accuracy across all five measures of recidivism. With one exception, these relations did not vary by gender, age, or ethnicity; and again with one exception, no significant evidence was found that types of family or household relationships moderated those empirical relations. In short, the evidence suggested that the DVSI-R was a robust risk assessment instrument, having applicability across different types of perpetrators and different types of family and household relationships. Finally, the empirical findings showed that structured clinical judgment about imminent risk-to-victim and risk-to-others corresponded with the prediction of recidivism by the DVSI-R total numeric risk scores, but the effects of those scores were significantly stronger than the perceived risk-to-victim or the perceived risk-to-others.     

Assessing the Impact of the 1996 Thai Prostitution Law: A Study of Police Arrest Data

The purpose of this paper was to evaluate the impact of the Thai Prevention and Suppression of Prostitution Act of 1996 in ten geographical regions of the country. This paper also addresses law enforcement approaches in controlling prostitution. Data for prostitution arrests from 1995 to 1998 were obtained from official police sources (Statistics of Reported Crimes of Thailand). ARIMA intervention analysis was employed; revealing the arrest rates of prostitutes between pre- and post-enactment of the present Prostitution Act did not differ statistically within the regions except for Region 8 (Phuket). The paper reaches two general conclusions: (1) the 1996 Thai prostitution law did not significantly reduce the arrest rate for prostitution across the country; and (2) further consideration must be given to the idea of decriminalizing prostitution, which might allow for licensure, improving health and living conditions as well as potentially limiting exploitation and impact crimes associated with the prostitution industry.     

Group-Based Dominance and Opposition to Equality Correspond to Different Psychological Motives

Social Dominance Orientation, one of the most popular individual differences measures in the study of generalized prejudice, can be understood as having two components: Opposition to Equality (OEQ) and support for Group-Based Dominance (GBD). We consider these components in terms of system justification theory and social identity theory. We find that each component best explains different kinds of political views, consistent with the theory that they arise from different motivations. OEQ reflects system justification motives. It better predicts attitudes towards redistributive social policy, political conservatism, and a lack of humanitarian compassion for the disadvantaged. GBD reflects social identity motives. It is more associated with hostility toward outgroups and concerns about intergroup competition. GBD and OEQ have different personality and demographic correlates, exhibit distinctive relations with explicit and implicit attitudinal preferences, and differentially predict a variety of policy attitudes. Use of GBD and OEQ as separate constructs enriches the understanding of prejudice, policy attitudes, and political ideology.     

Necessary and Universal Truths about Law?

Prominent analytical jurisprudents assert that a theory of law consists of necessary, universal truths about the nature of law. This often‐repeated claim, which has not been systematically established, is critically examined in this essay. I begin with the distinction between natural kinds and social artifacts, drawing on the philosophy of society to show that necessity claims about law require a fundamental reworking of basic understandings of ontology and epistemology, which legal philosophers have not undertaken. I show law is a poor fit for a priori and a posteriori knowledge. I distinguish between universal application and universal truth, showing the former is sound while the latter is not. I expose the implications that follow from the initial selection of the central case of law, demonstrating that this choice must be justified, and I reveal two ways analytical jurisprudents shield their theories of law from refutation. This analysis raises significant doubts about the claim by analytical jurisprudents that they are identifying necessary, universal truths about the nature of law.     

The Promise and Problems of Universal,General Theories of Contract Law

There are a growing number of general theories of contract law and of other doctrinal areas. These theories are vastly ambitious in their aims. This article explores the nature of these claims, and the motivations for offering such theories, while considering the challenges to success. It is in the nature of theorizing to seek general categories, including doctrinal categories, and to try to discover insights that hold across those categories. However, differences both within a doctrinal area and across legal systems undermine the case for universal and general theories. Also, unjustifiably general theories may distract us from developing properly contextual legal rules, and might even have the unintended effect of legitimating unjust rules.
