We compute the equivariant K-homology of the classifying space for proper actions, for cocompact 3-dimensional hyperbolic reflection groups. This coincides with the topological K-theory of the reduced C*-algebra associated to the group, via the Baum-Connes conjecture. We show that, for any such reflection group, the associated K-theory groups are torsion-free. This means that we can complete previous computations with rational coefficients to get results with integral coefficients. On the way, we establish an efficient criterion for checking torsion-freeness of K-theory groups, which can be applied far beyond the scope of the present paper. [less ▲]

La présente contribution est conçue sous forme d'un rapport d'atelier et donne un premier aperçu concernant le développement d'une approche des phénomènes de frontières et d'espaces frontaliers sur la base des études culturelles. Cette approche tente d'être plus large que celle correspondant aux perspectives jusqu'à présent préconisées par les sciences sociales et appréhende les phénomènes des frontières et des espaces frontaliers en tant qu'entités composées de différentes pratiques et différents discours faisant référence aux frontières et aux différences. Ces entités comprises au sens de bordertextures sont exemplairement illustrées à travers des phénomènes concernant la frontière entre les États-Unis et le Mexique, la frontière franco-allemande et l'Irlande du Nord et elles sont déclinées en différentes dimensions d'analyse. Parmi ces dernières, la corporéalité, la spatialité et la matérialité figurent parmi les approches heuristiques des bordertextures que la présente contribution aborde à titre d'exemples. L'approche relativise la perspective largement répandue correspondant à une conception territoriale de la frontière pour élargir la palette des perspectives analytiques et celles des domaines analysés au sein des Border Studies.

countries. It views educational institutions as a key producer of social cohesion by supplying the shared beliefs that generate shared cultural meanings. To most institutionalists, education (schools, colleges, universities, but also home schooling, religious, and informal education) stands out as one of only a handful of key social institutions next to the family, the economy, religion, science, and government. Higher education takes its place in this nexus of institutions, as it globally expands in size and grows in strategic importance. [less ▲]

Code smells are symptoms of poor design or implementation choices that have a negative effect on several aspects of software maintenance and evolution, such as program comprehension or change- and fault-proneness. This is why researchers have spent a lot of effort on devising methods that help developers to automatically detect them in source code. Almost all the techniques presented in literature are based on the analysis of structural properties extracted from source code, although alternative sources of information (e.g., textual analysis) for code smell detection have also been recently investigated. Nevertheless, some studies have indicated that code smells detected by existing tools based on the analysis of structural properties are generally ignored (and thus not refactored) by the developers. In this paper, we aim at understanding whether code smells detected using textual analysis are perceived and refactored by developers in the same or different way than code smells detected through structural analysis. To this aim, we set up two different experiments. We have first carried out a software repository mining study to analyze how developers act on textually or structurally detected code smells. Subsequently, we have conducted a user study with industrial developers and quality experts in order to qualitatively analyze how they perceive code smells identified using the two different sources of information. Results indicate that textually detected code smells are easier to identify and for this reason they are considered easier to refactor with respect to code smells detected using structural properties. On the other hand, the latter are often perceived as more severe, but more difficult to exactly identify and remove. [less ▲]

Web application firewalls (WAF) are an essential protection mechanism for online software systems. Because of the relentless flow of new kinds of attacks as well as their increased sophistication, WAFs have to be updated and tested regularly to prevent attackers from easily circumventing them. In this paper, we focus on testing WAFs for SQL injection attacks, but the general principles and strategy we propose can be adapted to other contexts. We present ML-Driven, an approach based on machine learning and an evolutionary algorithm to automatically detect holes in WAFs that let SQL injection attacks bypass them. Initially, ML-Driven automatically generates a diverse set of attacks and submit them to the system being protected by the target WAF. Then, ML-Driven selects attacks that exhibit patterns (substrings) associated with bypassing the WAF and evolve them to generate new successful bypassing attacks. Machine learning is used to incrementally learn attack patterns from previously generated attacks according to their testing results, i.e., if they are blocked or bypass the WAF. We implemented ML-Driven in a tool and evaluated it on ModSecurity, a widely used open-source WAF, and a proprietary WAF protecting a financial institution. Our empirical results indicate that ML-Driven is effective and efficient at generating SQL injection attacks bypassing WAFs and identifying attack patterns. [less ▲]

Tax Treaty dispute resolution through the Mutual Assistance Procedure (MAP) is particularly relevant in Luxembourg. Luxembourg has, as of May 2018, 81 Double Tax Convention (henceforth, “DTC”) out of which only 12 provide for arbitration clauses. In contrast, while the Arbitration procedure is also available, it is barely used in practice as the MAP procedure proves to be the most common form of resolution of tax treaty dispute resolutions in Luxembourg.

Jugendliche aus stationären Einrichtungen (z.B. Heime) sind häufig von der Chronifizierung einer psychischen Störung bedroht [Schmid, 2007]. Unter anderem aufgrund von Traumatisierungen sind externalisierende Verhaltensprobleme, z.B. wiederholter unangemessener Ärgerausdruck, festzustellen, die einen Behandlungserfolg in Frage stellen. Erforderlich ist es daher problematische Ärgerreaktionen von Jugendlichen zu thematisieren, und den Umgang mit Ärger zu verändern. In dieser Falldarstellung wird die Umsetzung eines 10-wöchigen kognitiv-verhaltenstherapeutischen Ärgerbewältigungstrainings [Schwenkmezger et al., 1999] bei einem fremdplatzierten verhaltensauffälligen Jugendlichen aufgezeigt [Steffgen et al., 2014]. Die eingesetzten testdiagnostischen Verfahren belegen, dass die Bereitschaft zu aggressiven Verhaltensweisen sowie des nach außen gerichteten Ärgerausdrucks reduziert, und die Ärgerkontrolle erhöht wurde. Insgesamt konnte die Wirksamkeit der programmgestützten Intervention am Einzelfall nachgewiesen werden. Jugendliche in der Heimunterbringung können somit durch die Teilnahme an einer Ärgerintervention Nutzen ziehen, indem sie lernen ihre Emotionsregulation zu optimieren, um dadurch ihre soziale Kompetenz zu erhöhen. Ihre gesellschaftliche Eingliederung ließe sich dadurch erleichtern. [less ▲]

Common variants of about 20 genes contributing to AD risk have so far been identified through genome-wide association studies (GWAS). However, there is still a large proportion of heritability that might be explained by rare but functionally important variants. One of the so far identified genes with rare AD causing variants is ADAM10. Using whole-genome sequencing we now identified a single rare nonsynonymous variant (SNV) rs142946965 [p.R215I] in ADAM17 co-segregating with an autosomal-dominant pattern of late-onset AD in one family. Subsequent genotyping and analysis of available whole-exome sequencing data of additional case/control samples from Germany, the UK and the USA identified five variant carriers among AD patients only. The mutation inhibits pro-protein cleavage and the formation of the active enzyme, thus leading to loss-of-function of ADAM17 α-secretase. Further, we identified a strong negative correlation between ADAM17 and APP gene expression in human brain and present in vitro evidence that ADAM17 negatively controls the expression of APP. As a consequence, p.R215I mutation of ADAM17 leads to elevated Aß formation in vitro. Together our data supports a causative association of the identified ADAM17 variant in the pathogenesis of AD.

Die hohe und gestiegene Bedeutung inklusiver Bildung – für Individuen und Gesellschaften gleichermaßen – wird global, national, regional und lokal von verschiedensten Akteur*innen hervorgehoben sowie zunehmend auch wissenschaftlich multidisziplinär diskutiert. Fragen der Steuerung, der Governance, hingegen, sind bisher im deutschsprachigen Raum nur wenig systematisch oder umfassend analysiert worden, obwohl mehrere Wissenschaftsdisziplinen sich zunehmend mit diesen Fragen auseinandersetzen. Während politikwissenschaftliche Analysen die Machtstrukturen, Pfadabhängigkeiten und Entscheidungsprozesse fokussieren haben soziologische Analysen die globale Diffusion von Diskursen und Normen sowie systembedingte Komplexitäten und Umsetzungsschwierigkeiten vielfältiger Reformen verdeutlicht. Die Erziehungswissenschaft, nicht nur in der deutsch-sprachigen Welt, hat sich lange Zeit schwer getan, sich eindeutig zu den brisanten bildungs- als auch sozialpolitischen Fragen der inklusiven Bildung – auch die zentrale Frage der Governance – zu positionieren, weil es das fundamentale Verhältnis von Allgemeiner und Sonderpädagogik hinterfragt sowie in letzter Konsequenz die Transformation des gegliederten und hochgradig selektiven Bildungswesen verlangt. Dieser Band beleuchtet eben dieses Spannungsverhältnis aus verschiedenen Perspektiven; in diesem Beitrag wird deshalb versucht, verschiedene Dimensionen der Governance auf der Forschungsagenda zu platzieren, wie auch in zwei konkreten Fällen – Deutschland und Luxemburg – zu vertiefen.

While the EU Treaties do not contain a general anti-abuse rule, the Court of Justice of the European Union (ECJ) uses the concept of abuse of law when interpreting the EU Treaties in multiple substantive areas of law, including direct taxation. Current EU mechanisms for protection against abusive practices have that case law as a common root. This Report therefore starts by evaluating the emergence of the concept of abuse in the case law of the ECJ with regard to the fundamental freedoms. In this respect, the Court has accepted that discriminatory anti-avoidance rules can be justified by overriding reasons in the general interest but only where such rule specifically relates to wholly artificial arrangements aimed at circumventing the application of the legislation of the Member State concerned. Moreover, general and special anti-abuse provisions are enshrined in secondary EU law instruments. This concerns the general anti-avoidance rule for the area of corporate taxation, which was introduced by the Anti-Tax Avoidance Directive (ATAD) and will be effective from 1 January 2019, and the more specific rules in the Parent-Subsidiary Directive (PSD), the Merger Directive (MD) and the Interest-Royalty Directive (IRD). This Report explains the scope of these provisions, their interpretation and application, and their relationship with primary EU law, tax treaties and national law. Finally, this Report provides a brief outlook on the impact of EU law on domestic tax systems in this field, stressing that general anti-abuse measures might create tensions with fundamental taxpayers’ rights, such as the right to legal certainty and the freedom to arrange one’s economic affairs.

Social networks are expected to matter for invention in cities, but empirical evidence is still puzzling. In this paper, we provide new results on urban patenting covering more than twenty years of European patents invented by nearly one hundred thousand inventors located in France. Elaborating on the recent economic literatures on peer effects and on games in social networks, we assume that the productivity of an inventor’s efforts is positively affected by the efforts of his or her partners and negatively by the number of these partners’ connections. In this framework, inventors’ equilibrium outcomes are proportional to the square of their network centrality, which encompasses, as special cases, several well-known forms of centrality (Degree, Katz-Bonacich, Page-Rank). Our empirical results show that urban inventors benefit from their collaboration network. Their production increases when they collaborate with more central agents and when they have more collaborations. Our estimations suggest that inventors’ productivity grows sublinearly with the efforts of direct partners, and that they incur no negative externality from them having many partners. Overall, we estimate that a one standard deviation increase in local inventors’ centrality raises future urban patenting by 13%. [less ▲]
