The difficult issue of age assessment on pedo-pornographic material

The issue of juvenile pornography has seen an increase in the past few years of the number of expert opinions requested to forensic pathologists, paediatricians and other various experts within the forensic and medical fields concerning the age of represented individuals. Regardless of the entity of the problem, no actual method exists which can allow us to give an objective and scientific answer, particularly in the postpubertal stage. Using parameters related to sexual maturation can be very dangerous. Nonetheless some experts still insist with similar types of “expertises”. This study aims at verifying the ability of different experts in assessing age of postpubertal individuals represented in pornographic material. Results underline the difficulties and major uncertainties of age evaluation by visual observation of photographic material particularly when the subjects have reached the sexual maturation stage – and therefore in verifying whether the individual is above or below 18 years of age (an important age limit for most European countries as far as this type of crime is concerned). Furthermore the study stresses the need both to search for an alternate approach and to apply extreme caution in judicial evaluation.

Threshold Concepts Through Enactive Learning: How Effective Are They in the Study of European Politics?

Studying European Politics can be a challenge! And this is not surprising: even the best scholarly minds of European politics often struggle to give precise definition to such a young, but already so complex and constantly evolving polity as the European Union, and are increasingly at odds with identifying its prospects for survival. One way to achieve a better understanding of the subject is to utilize a threshold concept approach, which is essentially a "less is more" approach that chooses to work with a few "founding" concepts, and identifies a "road map" for independent learning of broader but essentially inter-connected issues of the discipline. The threshold concept approach becomes even more effective if combined with enactive learning—that is, learning-by-doing, through role taking and simulation of the threshold concepts during seminars. Such learning evidently exceeds the boundaries of conventional knowledge and becomes a useful transferable investment for the future.     

International Soft Law, Human Rights and Non-state Actors: Towards the Accountability of Transnational Corporations?

During this age of globalisation, the law is characterised by an ever diminishing hierarchical framework, with an increasing role played by non-state actors. Such features are also pertinent for the international enforceability of human rights. With respect to human rights, TNCs seem to be given broadening obligations, which approach the borderline between ethics and law. The impact of soft law in this context is also relevant. This paper aims to assess whether, and to what extent, this trend could be a proper path to enforce the legal accountability of transnational corporations for human rights. It will be argued that the interplay between law and ethics should be assessed differently depending on which kind of correlative duty is at stake. With regard to negative duties, soft law tools concerning TNCs’ conduct may weaken the impact of hard law. By contrast, when positive duties are concerned, insofar as the horizontal effect of rights cannot be assumed, soft law turns out to be much more useful.

Sex estimation in a Turkish population using Purkait’s triangle: a virtual approach by 3-dimensional computed tomography (3D-CT)

Sex estimation is considered one of the first steps in the forensic identification process. Morphological and morphometrical differences between males and females have been used as means for morphoscopic and metric methods on both cranial and postcranial skeletal elements. When dry skeletal elements are not available, virtual data can be used as a substitute. The present research explores 3-dimensional (3D) scans from a Turkish population to test a sex estimation method developed by Purkait (2005).Overall, 296 individuals were used in this study (158 males and 138 females). Purkait’s triangle parameters were measured on computed tomography (CT) scans obtained from both right and left femora of each patient at the Bakirkoy Dr. Sadi Konuk Training Research Hospital (Istanbul, Turkey). Intra- and inter-observer errors were assessed for all variables through technical error of measurements analysis. Bilateral asymmetry and sex differences were evaluated using parametric and non-parametric statistical approaches. Univariate and multivariate discriminant function analyses were then conducted.Observer errors demonstrated an overall agreement within and between experts, as indicated by technical error of measurement (TEM) results. No bilateral asymmetries were reported, and all parameters demonstrated a statistically significant difference between males and females. Fourteen discriminant models were generated by applying single and combined parameters, producing a total correct sex classification ranging from 78.4% to 92.6%. In addition, over 67% of the total sample was accurately classified, with 95% or greater posterior probabilities.Our study demonstrates the feasibility of 3D sex estimation using Purkait’s triangle on a Turkish population, with accuracy rates comparable to those reported in other populations. This is the first attempt to apply this method on virtual data and although further validation and standardisation are recommended for its application on dry bone, this research constitutes a significant contribution to the development of population-specific standards when only virtual data are available.

Key points

• CT analysis using Purkait’s triangle is a suitable tool for assessment of sex in unidentified individuals.
• The best overall estimation rate was achieved with the F11 model, with around 92% of accuracy.
• The results suggested 78.4% to 92.6% correct sex identification rates.
• More research is needed to expand the sample set and verify the results.

     

Contemporary Russian conservatism

This article analyzes contemporary Russian conservatism through the prism of ideational and positionist ideological perspectives. The author argues that Russian conservatism proposes a distinct value package through its anthropocentric nature, its plans for modernization of Russia, and its future outlook that must rest on the best elements of tradition. The author compares these trends with the Western conservative tradition, making distinct parallels between the two strands of conservative thought. The author also explores the attitude of Russian conservatism toward the post-modern world. This is intrinsically linked to the discussion of Russia's attempts to develop a political and ideational alternative to the West, introduce a distinct model for the architecture of international relations, and find Russia's position in the global world.     

Development of a heptaplex PCR system to analyse X-chromosome STR loci from five Italian population samples. A collaborative study

Many X-chromosome short tandem repeats (X-STRs) have been validated for forensic use even if further studies are needed on allele frequencies and mutation rates to evaluate the extent of polymorphism in different populations and to establish reference databases useful for forensic applications and for anthropological studies. A single multiplex reaction of seven X-STRs, which includes the DXS6789, HUMARA, DXS10011, DXS7423, HPRTB, DXS6807, DXS101 loci, is presented and their allele frequency distribution in a large population sample including 556 subjects (268 females and 288 males) analysed by five forensic laboratories of Central and Northern Italy is shown. Our results demonstrate the feasibility of a single amplification/detection reaction involving seven markers of the X chromosome, which can be fruitfully used in complex kinship analysis.     

Russia’s idea of the multipolar world order: origins and main dimensions

Contemporary international relations are rife with the ideological struggle over the potential nature of the rapidly changing world order. Two distinct paradigmatic positions have surfaced. One champions economic, cultural, and political globalization conducted under the leadership of the Western world. The other advocates a more particularistic approach that fends for a balance of interests, multiplicity of politico-cultural forms and multiple centers of international influence. The latter doctrine, often referred to as the multipolar world theory, is the subject of this paper. The discussion argues that the idea of a multipolar world order has emerged as Russia’s main ethical and ideological position advanced in the international arena. Its philosophical tenets buttress Russian society intellectually at home, providing the expedients to pursue the country’s foreign policy goals abroad. The paper examines a substantial value package with roots in both Russian and Western philosophy that sustains the multipolar world order theory.
