Genetic study of 15 STRs loci of Identifiler system in Angola population

Angola is located in the African continent, in the area of southern Africa and has a population of approximately 14 million inhabitants. The Angola population has origin from Occidental and Southern Bantu people that came from the great lakes region, creating the most ever known African migration of our days.Allele frequencies for the 15 STRs loci in the AmpFlSTR Identifiler kit (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, HUMTH01, D13S317, D16S539, D2S1338, D19S433, HUMVWA, TPOX, D18S51, D5S818, HUMFIBRA/FGA and including the segment of the X-Y homologous gene amelogenin) were studied for Angola population.The genotype frequency of the 15 STR loci showed no significant deviations from Hardy–Weinberg equilibrium expectations and great values for the combined power of discrimination and combined power of a priori exclusion validate the application of these markers in forensic genetics. Comparative analyses between Angola population data and other relevant population database from Africa, Europe and American are presented.     

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.     

Innovation capital

In this paper we compare the relationship between a firm’s innovation capital and the likelihood that a firm will commercialize an invention. Our index of innovation capital is the product of the firm’s human capital, social capital, and reputational capital. We find from our empirical experiment, which uses Small Business Innovation Research data, that innovation capital is a statistically more important entrepreneurial input to the innovation output of commercialization than any of its components.     

Temporal Trends in Rainwater Tank Suicides in Rijeka,Croatia—A 30‐year Study

Although drowning in rainwater tanks is a generally rare phenomenon, this method for suicide has been observed in parts of Croatia. Review of autopsy records at the University of Rijeka, Croatia, was undertaken from 1987 to 2016 to examine this phenomenon. Of 469 drowning deaths, there were 35 suicides in rainwater tanks (7.5%). Overall drowning deaths showed no temporal trends. In contrast, suicidal drownings in rain water tanks showed a marked decline over the years, with 15 cases in 1987–1991, seven in 1992–1996, six in 1997–2001, six in 2002–2006, one in 2007–2011, and none in 2012–2016. Thus, suicidal drowning cases as a percentage of overall drownings dropped from 18% to zero (p<0.001). This study reports a very unusual method of suicide that may have occurred because of the ready availability of large water reservoirs in homes. The recent fall in numbers may relate to less reliance on domestic reservoirs of water.     

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.     

South African–Swaziland relations: A constructivist reading

There are several accounts of the past relations between Swaziland and South Africa. Some are set in the realist school of international relations scholarship. These studies portray Swaziland's policy behaviour as ‘submissive’ because of ‘immutable structural forces’. The neo-Marxian analyses locate the relations exclusively in class/ideological setting. Other accounts depict the ‘kaleidoscopic’ nature of the relations. The post-apartheid understanding of this relationship is largely gleaned from regional studies – the dominant view of which is that South Africa is reluctant to exercise hegemony in its relations with regional states. This article critiques the one-directional thrust of the realist and Marxian accounts. While endorsing multidirectional and multidimensional accounts of policy behaviour, the article shows that they lack an over-arching theoretical framework. A similar charge is directed at the post-apartheid literature. The position of this article is that constructivism offers analytical tools needed to understand the relations between the two states and how South Africa can reorder them.     

Partner similarity for self-reported antisocial behaviour among married,cohabiting and dating couples: the Generation R Study

Abstract

From a criminological perspective, romantic relationships are supposed to decrease the risk of antisocial behaviour (Laub, Nagin, & Sampson, American Sociological Review, 63, 225–238, 1998). However, the effects of these relationships probably depend on the romantic partner's behaviour. In the current study we examined partner similarity for antisocial behaviour in an ethnically heterogeneous community sample of 4135 married, cohabiting and dating couples from Rotterdam, the Netherlands, using self-reports. Spousal correlations were consistently positive for antisocial behaviour but differed in strength according to the type of antisocial behaviour. Associations between spouses remained strong after adjusting for age and educational level depending on the type of antisocial behaviour. In addition, antisocial behaviour was positively associated between partners across marital status and ethnicity, but the strength of this association varied to some extent. Results are discussed in light of the phenotypic assortment, the socialization and the social homogamy hypotheses.
