Possible pitfalls in motherless paternity analysis with related putative fathers

Nowadays, more and more paternity cases are carried out investigating only child and putative father, mostly for economical or private reasons. Usually, reliable results can be obtained and the putative father can be included or ruled out with a high certainty. Considerable problems might arise when a relative of the biological father is investigated as being the putative father. In this study, we investigated 164 persons from 27 families creating artificial deficiency cases using the AmpFlSTRIdentifiler kit, which amplifies 15 STRs simultaneously. We analyzed 93 child/biological father pairs and the corresponding uncles, respectively the brothers of the biological fathers. The average paternity probability for the biological father was 99.9699% (paternity index (PI): 3321.26); only in three cases the results were under 99.9%. In five out of 125 child/uncle pairs no STR mismatches were found and paternity probabilities between 99.9726% (PI 3652) and 99.9970% (PI 33,545) were calculated. The average number of excluding loci was 3.4, but in 31.2% of the cases only zero, one or two mismatches were found. When both putative fathers were genetically typed, the biological father usually had a statistically higher paternity probability. Nevertheless, the differences between probabilities for father and uncle were only small. These results show that a reliable investigation of deficiency cases (i.e. child and putative father) seems to be more difficult than generally assumed. Especially in cases with an unknown familiar background and/or when investigating foreigners for immigration purposes, the laboratory expert should include the mother, increase the number of investigated loci or include a second method such as RFLP-analysis, some serological systems or typing of X-chromosome specific STRs to further ascertain the results.     

Development of a capillary zone electrophoresis method including a factorial design and simplex optimisation for analysis of amphetamine, amphetamine analogues, cocaine, and heroin

A capillary zone electrophoresis (CZE) method was developed for the analysis of amphetamine and 13 amphetamine analogues. A full factorial design was used to screen for important design variables (i.e. carrier electrolyte concentration, pH, and separation temperature), and a modified simplex was employed in a final optimisation step. The resolution values of the target compounds were used as responses in the screening and optimisation phases. This approach made it possible to control the effects of the design variables on the separation of the target compounds. The best results were obtained using a 100mM Tris/phosphate buffer (pH 3.1) at a separation temperature of 10 degrees C, and the analysis time was 23 min under these conditions. After slight modification, the method also enabled baseline resolution of the most commonly encountered amphetamine derivatives, as well as cocaine and heroin, within 7 min. There was a linear relationship between peak area and concentration for all substances, with correlation coefficients in the range of 0.9975-0.9999. Moreover, the technique was repeatable and exhibited relative standard deviation (R.S.D.) values in the ranges of 0.01-0.11% and 0.54-1.60% for relative migration time and corrected peak area, respectively. Lastly, the method was successfully applied to analyse street samples.     

All Quiet on the Eastern Front? Media Images of the West and Russian Foreign Political Identity1

National and foreign political identities are discursively constructed, not least through the media. Starting from the contention that Europe serves as the main Other used to define the idea of Russia, this article uses media texts (online and press) to analyse how Russia is constructed as a foreign policy actor in relation to Europe and the ‘West’ more generally. In so doing, the article draws on three discourses around Russia’s foreign policy: ‘Russia as Europe’; ‘Russia as part of Greater Europe’; and ‘Russia as Alternative Europe’. The article suggests that discursive developments in the 2000s have paved the way for a return of Cold War discourses in characterising relations between Russia and the West.     

Transnational organized crime challenges for future research

This essay and review seeks to assess the state of empirical research on transnational organized crime, drawing on a review of the English language academic literature. It identifies major themes and research questions as well as methodological approaches, and summarizes key findings. It also addresses challenges to meaningful research, arguing that internationally coordinated research projects will be necessary in the future to arrive at the insights necessary to inform theory and policy.

European monetary policy and the ECB rotation model

This paper analyses the voting power of individual members of the ECB Governing Council and, in particular, that of the Executive Board in the light of recent information published by the ECB. Using the randomization scheme based on the multilinear extension of games, we modify the standard analysis in three ways. First, we include heterogeneous preferences of the Governing Council members. Second, we address the agenda-setting power of the ECB president. Third, we take into account the dynamic decision setting. We show that the rotation model is able to stabilize the position of the core countries of the euro area.     

Regulating government (’s share): the fifty-percent rule of the federal constitutional court in Germany

Some numbers in the political sphere seem to be chosen rather arbitrarily. One example might be the rule set out by the Second Senate of the German Federal Constitutional Court in 1995 that the overall tax load on assets must be limited to 50% of the yield on those assets. This rule was understood by many as a general principle for taxation. The article first sketches the socio-political climate under which the rule originated: a rise of neo-liberal thought met with the inability of the political institutions to reform the German welfare state with its ever-growing expenses. The Constitutional Court’s intervention is interpreted as a reaction to this stagnation in politics. An analysis from the perspective of Constitutional Law, however, reveals that the 50% rule cannot be convincingly based on the German Basic Law, and instead must be seen as a political move of the Court. But this move did not follow an economic rationality, either; for an optimal government’s share can only be determined in relation to the economic performance of a country and not by fixing it generally at a maximum of 50% of GDP. The demise of the 50% rule already began four years later. In 2006, finally, the Senate moved away from the individual rights-based approach of 1995 to a more general assessment, taking also into account an increasingly globalized tax competition. The reason for this clear-cut change in the Court’s jurisprudence can be found in a change of the socio-political and institutional parameters, thus witnessing to the effect of the political climate on court decisions. The analysis also shows that the rule was created and abandoned only on the basis of an “introverted” legal discussion, economic arguments hardly playing any role in the process. The new line of the Senate, however, might guarantee for a better integration of economic science into tax policy by exchanging fixed limits for a “discursive” model, demanding from the tax legislator better reasons for higher taxes.
