A reliable and safety infrastructure for both transport and traffic is becoming increasingly important today. The condition assessment of bridges remains difficult and new methods must be found to provide reliable information. A meaningful in-situ assessment of bridges requires very detailed investigations which cannot be guaranteed by commonly used methods. It is known that the structural response to external loading is influenced by local damages. However, the detection of local damage depends on many factors such as environmental effects (e.g. temperature), construction layer (e.g. asphalt) and accuracy of the structural response measurement. Within the paper, a new so-called Deformation Area Difference (DAD) Method is presented. The DAD method is based on a load deflection experiment and does not require a reference measurement of initial condition. Therefore, the DAD method can be applied on existing bridges. Moreover, the DAD method uses the most modern technologies such as high precision measurement techniques and attempts to combine digital photogrammetry with drone applications. The DAD method uses information given in the curvature course from a theoretical model of the structure and compares it to real measurements. The paper shows results from a laboratory load-deflection experiment with a steel beam which has been gradually damaged at distinct positions. The load size is chosen so that the maximum deflection does not exceed the serviceability limit state. With the data obtained by the laboratory experiment, the damage degree, which can still be detected by the DAD method, is described. Furthermore, the influence of measurement accuracy on damage detection is discussed. [less ▲]

An important ongoing debate in the addiction field is whether certain technologymediated behaviors constitute tenable and independent constructs. This study investigated whether problematic technology-mediated behaviors could be conceptualized as a spectrum of related, yet distinct disorders (spectrum hypothesis), using the network approach that considers disorders as networks of symptoms. We used data from the Cohort Study on Substance Use and Risk Factors (C-SURF), with a representative sample of young Swiss men (subsample of participants engaged in technology-mediated behaviors, n=3,404). Four technology-mediated addictive behaviors were investigated using symptoms derived from the DSM-5 and the component model of addiction: Internet, smartphone, gaming, and cybersex. Network analyses included network estimation and visualization, community detection tests, and centrality indices. The network analysis identified four distinct clusters corresponding to each condition, but only Internet addiction had numerous relationships with the other behaviors. This finding, along with the finding that there were few relationships between the other behaviors, suggests that smartphone addiction, gaming addiction, and cybersex addiction are relatively independent constructs. Internet addiction was often connected with other conditions through the same symptoms, suggesting that it could be conceptualized as an “umbrella construct,” i.e., a common vector that mediates specific online behaviors. The network analysis thus provides a preliminary support to the spectrum hypothesis and the focus on the specific activities performed online, while showing that the construct of “Internet addiction” is inadequate.

Objective: Impulsivity is a multifaceted construct known to play a crucial role in the development and maintenance of a wide range of problematic behaviors and psychological disorders in children. Method: In this study, we adapted the short French adult version of the UPPS-P Impulsive Behavior Scale for use with children (short UPPS-P-C) and tested its psychometric properties. Results: Confirmatory factor analyses conducted on a sample of 425 children (aged from 8 to 14 years) supported the five-factor structure of the scale. Additional analyses emphasized the good internal and test-retest reliability of the short UPPS-P-C. Furthermore, our results also revealed that lack of premeditation and urgency subscales were able to discriminate between children diagnosed with attention-deficit/hyperactivity disorder (ADHD) and their matched controls. Conclusion: These results suggest that the short UPPS-P-C may be considered as a promising time-saving tool to assess impulsivity traits in healthy children and in children with psychiatric disorders.

Attack trees provide a systematic way of characterizing diverse system threats. Their strengths arise from the combination of an intuitive representation of possible attacks and availability of formal mathematical frameworks for analyzing them in a qualitative or a quantitative manner. Indeed, the mathematical frameworks have become a large focus of attack tree research. However, practical applications of attack trees in industry largely remain a tedious and error-prone exercise. Recent research directions in attack trees, such as attack tree generation, attempt to close this gap and to improve the attack tree state-of-thepractice. In this position paper we outline the recurrent challenges in manual tree design within industry, and we overview the recent research results in attack trees that help the practitioners. For the challenges that have not yet been addressed by the community, we propose new promising research directions. [less ▲]

This paper analyzes the effects of the inclusion of past experiences in measuring current material deprivation. The method followed generalizes the proposal of Bossert, Ceriani, Chakravarty and D'Ambrosio (2014) by adapting the class of indices on the measurement of poverty over time of Dutta, Roope and Zank (2013). An application to the analysis of material deprivation within EU countries is then provided. Following the path of material deprivation experienced by each individual over time yields a picture which differs from that in the annual results. Since the measurement of material deprivation is used by the EU member states and the European Commission to monitor national and EU progress in the fight against poverty and social exclusion, the results suggest that time cannot be neglected. Countries should not only be compared based on their year-by-year results, but additional information is gained by following individuals over time and producing an aggregate measure once dynamic considerations are taken into consideration.

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 ▲]

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 ▲]

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 ▲]
