National survey of the incidence of missing anterior teeth: Potential use in bite mark analysis in the Brazilian context

Bite mark analysis in forensic dentistry presupposes that the human dentition is unique and that its characteristics can be transferred precisely to several materials. The aim of the present study was to register the frequency of missing anterior teeth in the Brazilian adult population, discussing its potential importance in bite mark analysis. Data from the Brazilian Oral Health Survey were used; 13,431 male and female individuals aged 35 to 44 were examined according to the criteria of the World Health Organization. The analysis of Poisson regression was performed in order to calculate the rating ratios and the respective confidence interval at 95%. A total of 13,431 adults participated in the study. Among male individuals, 2063 (47.00%) were dentate and 2036 (46.40%) had at least one missing tooth. Only 254 (5.83%) were totally edentulous. A significant number of males and females presented 6 missing teeth in the same dental arch, revealing the poor state of oral health of adult Brazilians. Missing teeth were more frequent in the upper dental arch than in the lower arch. In the upper dental arch, the incisor group (central and lateral) was missing the most. In the lower dental arch, however, a certain lack of homogeneity was observed among the different dental groups as regards missing teeth. White individuals presented a smaller proportion of missing teeth compared to the other ethnic groups. Females were 1.61 (CI 1.50–1.73) times more likely than males to present missing teeth. The absence of upper teeth and the presence of lower teeth were observed in 16.10% of the individuals. Further research should also include an analysis of different age groups. This would increase the potential of applying this kind of information to bite mark analysis.     

The Economic Cost of March 11: Measuring the Direct Economic Cost of the Terrorist Attack on March 11, 2004 in Madrid

This article attempts to measure the direct costs that the terrorist attacks of 3/11 had on the economy of the region of Madrid. The evaluation has been made applying conservative criteria, and the results obtained have to be considered as minimum. The result indicates that the terrorist attacks caused a loss of nearly 212 million euros to the regional economy of Madrid, equivalent to 0.16 percent of the regional GDP (0.03 of the national GDP). This confirms that the immediate economic dimension of a terrorist attack such as the one of 3/11—apart from human catastrophic consequences—is relatively low.     

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.     

Development Dynamics of Chinese Resource‐Based Investment in Peru and Ecuador

This article analyzes the developmental impact of two of the earliest investments made by Chinese companies in South America, the Shougang Corporation's mining activities in Peru and Andes Petroleum's oil extraction operations in Ecuador. The article draws attention to the importance of contextualizing and disaggregating instances of Chinese resource‐based investment in order to adequately grasp the complexity of processes that are contingent to particular regimes of natural resource governance, companies' backgrounds, and the strength and nature of local reactions, among other factors. It thereby encourages a critical examination of Chinese investment in South America that explores how the characteristics of that investment are reshaped by the long and contested histories of resource extraction in the region, the promotion of and resistance to particular visions of development, the agency of multiply situated and complex actors, and the wider transnational production networks in which resource extraction processes are embedded.     

The relationship of compliance with anxiety,self-esteem,paranoid thinking and anger

Abstract

The aim of the study was to assess the relationship of compliance with anxiety, self-esteem, paranoid thinking, and anger. The Gudjonsson Compliance Scale (GCS), the State-Trait Anxiety Inventory (STAI), the Rosenberg Self-Esteem Scale, the Paranoia/Suspiciousness Questionnaire (PSQ), and the Novaco Anger Scale (NAS) were administered to 167 University students Compliance correlated positively with state and trait anxiety, low self-esteem, paranoia and suspiciousness, and negatively with acting out feelings of anger (the Behavioural Domain of the NAS). Multiple regression of the test scores showed that paranoid thinking was the single best predictor of compliance. The implications are discussed. It is important to replicate the study on special populations, such as offenders and psychiatric patients, who have problems with low self-esteem, paranoid thinking, and anger.
