Evaluation of a Freezer Mill for Bone Pulverization prior to DNA Extraction: An Improved Workflow for STR Analysis

Traditional methods for bone pulverization typically generate heat, risking stability of DNA sample. SPEX? has developed cryogenic grinders which introduce liquid nitrogen to cool the sample and aid in the grinding process. In this study, the Freezer Mill 6970 EFM was used with two DNA extraction methods and routine downstream STR analysis procedures. DNA from as little as 0.1 g of bone powder was used to develop full STR profiles after freezer mill pulverization, and the method was reproducible. Further, no contamination was detected upon cleaning/reuse of the sample vials. There were no significant differences in DNA yield, STR alleles detected, or peak heights using the freezer mill as compared to traditional grinding, and successful DNA profiles were achieved from as low as 0.1 g of bone powder with this method. Overall, this work indicates that this cryogenic mill method may be used as a viable alternative to traditional tissue grinders.     

Study of the adhesion of explosive residues to the finger and transfer to clothing and luggage

It is important to understand the extent of transfer of explosive particles to different surfaces in order to better evaluate potential cross-contamination by explosives in crowded security controls such as those at airports. This work investigated the transfer of nine explosive residues (ANFO, dynamite, black powder, TNT, HMTD, PETN, NH₄NO₃, KNO₃, NaClO₃) through fingerprints from one surface to another. First, the extent of adhesion of explosive residues from different surfaces to the bare finger, nitrile and latex gloves was studied. Then, the transfer of explosive residues from one surface to another through fingerprints was investigated. Cotton fabric (hereinafter referred to as cotton) as clothing material and polycarbonate plastic (hereinafter referred to as polycarbonate) as luggage material were chosen for the experiments. These surfaces containing explosive particles were imaged using a reflex camera before and after the particles were transferred. Afterwards the images were processed in MATLAB where pixels corresponding to explosive residues were quantified. Results demonstrated that transfer of explosive residues frequently occurred with certain differences among materials. Generally, the amount of explosive particles adhered to the finger decreased in the following order: skin>latex>nitrile, while the transfer of particles from the finger to another surface was the opposite. The adhesion of explosive residues from polycarbonate to the finger was found to be better compared to cotton, while the amount of particles transferred to cotton was higher.     

A Bilingual,Bicultural Approach to Detachment and Appraisal in the Law: Tracing Impersonality and Interaction in English and Spanish Legal Op-Eds

The present research study carries out a contrastive analysis between two corpora of legal opinion columns as special types of genres, with a view to assess their opposing patterns of impersonality—authorial detachment—and attitude—emotion, judgment, appreciation, taking as a point of departure appraisal theory, or the interpretation of Halliday's Systemic-Functional Linguistics (1994/2004) by the so-called Sydney School. The long-established perspective is that legal genres are highly impersonal; authoritative instruments representing an intentional exercise of elitist and exclusionary practices. However, the hypothesis embedded in the present study is that some texts, such as news editorials and op-eds, constitute hybrid genres where the writer makes use of all kinds of inducement devices to support his/her theses with effectiveness and credibility (Dafouz in J Pragmat 40:95-113, 2008), nonetheless retaining one of the basic traits of monogloss legal discourse: impersonality. However, it is hypothesized that this hybridity is to take place in different degrees, in tune with the influence exerted by legal system that constitutes the background of each corpus. To prove such a point, 40 legal op-eds—roughly, a thirty-five-thousand-word corpus in English and Spanish overall—were scrutinized, having been extracted from the specialized legal sections of two national newspapers of undisputed prestige as opinion-formation media. Through a contrastive study, the purpose of the present work was set to describe, explain and assess how lexicogrammar devices unveil interesting differences between the expression of impersonality and attitude in legal opinion columns as genres in either language, hence reflecting different ways in which the law is envisioned in each of the particular legal systems they belong to.     

Socialisation to interdisciplinary legal education: an empirical assessment

This article provides novel empirical survey evidence on socialisation factors leading lecturers to implement interdisciplinary teaching in law. Recent debates on legal scholarship and higher education legal institutions advocate the introduction of interdisciplinary approaches to legal studies. Nevertheless, there is still little evidence of how this lecturing philosophy might be affected by socialisation with other disciplines. To address this, we analyse the case of external lecturers in the Faculty of Law at the University of Copenhagen in Denmark, who constitute the majority of the teaching staff in this institution. To explain the adoption of interdisciplinary teaching, we rely on socialisation factors connected to their former higher education and socialisation in research and multidisciplinary environments.     

Ambivalent sexism,empathy and law enforcement attitudes towards partner violence against women among male police officers

Police attitudes towards partner violence against women (PVAW) can play an important role in their evaluation and responses to this type of violence. The present study aims to examine ambivalent sexism and empathy as determinants of male police officers' law enforcement attitudes towards PVAW. The study sample was composed by 404 male police officers. Results suggested that male police officers scoring low in benevolent sexism expressed a general preference for unconditional law enforcement (i.e. regardless of the victim's willingness to press charges against the offender), whereas those scoring high in benevolent sexism expressed a preference for conditional law enforcement (i.e. depending on the willingness of the victim to press charges against the offender). Results also showed that police officers scoring high in empathy and low in hostile sexism were those who expressed a general preference for unconditional law enforcement. The presence of sexist attitudes and low levels of empathy among some police officers, and their influence on law enforcement attitudes, highlights not only the importance of specific training, but also the need to pay attention to the selection process of police officers dealing with PVAW.     

‘Done to death by father or relatives’: Irish families and infanticide cases, 1922–1950

In February 1929 the Bishop of Ossory commented on the fact that in Ireland illegitimate infants were often ‘done to death by father or relatives’ (Irish Catholic, 16 February 1929). There were many instances where family members of unmarried women who gave birth were the sole defendants or co-defendants in infanticide cases in post-independent Ireland. Although illegitimate infants were ‘done to death’ by their fathers in a number of cases that were tried at the Central Criminal Court in Dublin between 1922 and 1950, this article will focus on cases where infants were murdered or suspected of having been murdered by relatives of the birth mother both in the Twenty-Six Counties and in Northern Ireland (Irish Catholic, 16 February 1929). For the purposes of this article I have referred to the murder of illegitimate infants as ‘infanticide’ even though there was no separate charge of infanticide in the Irish Free State until 1949. The English infanticide acts of 1922 and 1938 also applied to Northern Ireland. This article discusses the motives of the relatives of single mothers who played a part in the deaths of illegitimate infants. Unmarried motherhood was severely frowned upon in Ireland and the relatives of single pregnant women assisted their female kin in destroying the evidence of extra-marital conception in order to protect the family's honour and moral reputation in the wider community. The records of infanticide trials provide a great deal of insight into the ways in which mainly working-class families dealt with the strain of pregnancy outside wedlock in Ireland between 1922 and 1950.     

Rethinking UK Parliamentary Adaptation in EU Affairs: Devolution and Europeanisation

How national parliaments adapt to the European Union is an important debate. However, scholars often overlook the regional aspect. This is particularly so for the UK where, despite devolution since 1999, scholarship remains largely devolution-blind. It is assumed that evaluating UK parliamentary adaptation only requires assessing the work of Westminster committees. This article takes a first step towards rectifying this oversight through reconceptualising UK–EU parliamentary engagement as multi-territory, not state-centric. This is demonstrated by comparing the social construction of practices in Scotland, Wales and at Westminster since 1999. Acknowledging devolution, however, does not just require comparing practices. Additionally, the paper asks how the ideas of devolution have been taken up by actors, potentially transforming the meaning of UK engagement for them. This necessitates new approaches drawn from interpretivist and constructivist institutionalist theories. Ultimately, therefore, the paper goes further than arguing for devolution-aware research to promoting change more generally in how parliamentary adaptation is theorised.     

Costa Rica's biodiversity law: Sharing the process 1

Abstract

This article assesses the prospects for Costa Rica's new Biodiversity Law. We believe that this analysis could also provide a valuable case study of national implementation of the Convention on Biological Diversity (CBD). The article is not intended to be a primer on the CBD, nor will it defend its precepts. The authors believe that each nation must formulate a legal framework to regulate biodiversity that reflects their unique national circumstances.
