Distance bounding protocols allow a verifier to both authenticate a prover and evaluate whether the latter is located in his vicinity. These protocols are of particular interest in contactless systems, e.g. electronic payment or access control systems, which are vulnerable to distance-based frauds. This survey analyzes and compares in a unified manner many existing distance bounding protocols with respect to several key security and complexity features. [less ▲]

New generation of free trade agreements (CETA, TTIP, agreements with Singapore, China, Vietnam, Japan i.e.) are the expression of the objective of making the European Union a global international actor. The external action of the Union is however dependent on the principle of conferral and the division of competences with its Member States. It results from Opinion 2/15 of the Court of Justice that the EU competence to conclude the free trade agreement with Singapore is not exclusive, as long as provisions concerning non-direct investments and dispute settlement fall under the shared competence of the Union and its Member States. The limits of the Union’s external competence and the conclusion of a mixed agreement jeopardise the effectiveness of the Union’s external action. However, the objective of an efficient external action allows a novel interpretation of the scope of the Union’s competence in the field of common commercial policy, comprising sustainable development provisions, as well as of the conditions of exercise of shared external competences.

We present a simple open-source semi-intrusive computational method to propagate uncertainties through hyperelastic models of soft tissues. The proposed method is up to two orders of magnitude faster than the standard Monte Carlo method. The material model of interest can be altered by adjusting few lines of (FEniCS) code. The method is able to (1) provide the user with statistical confidence intervals on quantities of practical interest, such as the displacement of a tumour or target site in an organ; (2) quantify the sensitivity of the response of the organ to the associated parameters of the material model. We exercise the approach on the determination of a confidence interval on the motion of a target in the brain. We also show that for the boundary conditions under consideration five parameters of the Ogden-Holzapfel-like model have negligible influence on the displacement of the target zone compared to the three most influential parameters. The benchmark problems and all associated data are made available as supplementary material. [less ▲]

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 ▲]

By and large, we take our universities for granted. Indeed, the oldest have outlived political regimes of all kinds. This stimulating historical and comparative study exemplifies the importance of in-depth experience and engagement with the cultural and structural environments in which some of the world’s greatest universities have over centuries incrementally developed and been embedded. This is crucial if we hope to understand the sources of their authority and myriad contributions to scientific knowledge and human flourishing. A neo-institutionalist scholar and multicultural citizen who fruitfully contributes to dialogues exploring core institutions in education and society on both sides of the Atlantic, Heinz-Dieter Meyer is uniquely placed to grapple with the complex processes of institutional learning and design that have made the German and American universities among the globally most productive. He also shows how they have influenced each other via the complex, yet crucial flows of inspired scholars and students carrying key idea(l)s with them for interpretation and application back home. The contributions of key actors, but also the outcomes of choices at critical junctures, such as the failure to establish a national state-funded university in the United States, take center stage in this engaging account of how the leaders of American universities adapted the German model, joining diverse concepts to design what has become the greatest uni-versity system in the world, yet one that remains nearly impossible to emulate due to the unique constellation of actors and institutional environment in which it developed. In eighteen chapters in four parts, The Design of the University: German, American, and “World Class” takes us from Göttingen and Berlin to Boston and to the world level as the scientific enterprise—and competition between scientists and the most crucial organizational form in which they conduct their experiments and make their arguments, the research university—becomes ever more global. Contributing to and inviting debate, Meyer’s main argument is that the American university has suc-ceeded based upon an institutional design—or, perhaps, a non-design—that on multiple levels facil-itates self-government and the identification of a niche within an extraordinarily large and differen-tiated higher education system. This is not a full-fledged historiographic treatment of a subject fa-vored by academics (permanently searching for reputational gains) and policymakers (as they in-creasingly launch research funding programs and evaluation systems to foster competition). Rather than a full-fledged sociology of science, this book creatively sketches the trajectories of German and American university development, emphasizing affinities as well as crucial differences, to ulti-mately argue that in fact “Humboldt’s most important ideas flourished in the American atmosphere of unrestricted institutional experimentation and vigorous self-government” (xiii). Interrogating what he calls the “design thinking” of eminent thinkers Adam Smith and Wilhelm von Humboldt, among others, Meyer traces the challenging, complex, and contingent learning processes in the adaptation of the German research university model to the American context, eventually becoming the most differentiated and “world-class” higher education system in the world. Asking about the reasons for the American university’s success, especially in comparison to the recent insti-tutional crisis of the German research university, albeit still extraordinarily productive, Meyer argues that this American meritocratic success story has institutional design (of self-government) at its heart. Enjoying the patronage of not one, but three major institutions—state, church, and market—the American university attained true autonomy and global preeminence through unparalleled wealth of patronage and an intricate system of checks and balances. In this line of argument, chart-ing the ascendancy from humble origins of what can hardly be called a system due its extraordinary diversity, Meyer concurs with David Labaree (2017), who’s A Perfect Mess [1] is a highly-suitable com-panion piece grounded in the history of American higher education. Contemporary architects of higher education policy globally, driven by the fantasy of “world class” labels, Meyer warns, have completely underestimated the “institutional, social, and political prerequisites that excellence in research and teaching require” (p. 4). Meyer begins his treatise, appropriately, in Göttingen, the site of Georgia Augusta University, where many leaders of American higher education, first and foremost Boston Brahmin George Ticknor, learned by doing, ensconced in a cosmopolitan center of learning and intellectual enlightenment. The blueprint included professionalized scholarship, the unification of research and teaching in seminars and lectures, freedom to choose among academic offerings, a vast library of scientific knowledge, and academic standing based on perpetual production of cutting-edge research judged by peers (p. 19). Instead of Adam Smith’s preferred instruments of competition, choice, and tuition-dependence, Wilhelm von Humboldt’s “design revolution” proposed “three unities” whose powerful integration could surpass the utilitarian logic prevalent then and now: “teaching and research; scien-tific discovery and moral formation (Bildung); scholarly autonomy and scholarly community” (p. 40). The book’s second part, on institutional learning, charts the institutional migration of the blueprint; the contested design options of Gymnasium, college, and graduate school (the latter ultimately the key to global preeminence); the lasting influence of Protestantism (here Meyer follows the arguments of Max Weber, Robert K. Merton, and Joseph Ben-David) and extraordinary educational philanthropy; the battle between those who would centralize, by establishing a national university, and those committed to local control; and finally the contrasting answers to the eternal question of vocational-ism—e.g., how should business be treated, as a sibling to medicine and law or as their distant cousin? The more education-enamored, democratically-inclined patrician elites of the American East Coast were, Meyer argues, radically different institution-builders than German scholars, French state nobility, or even Chinese mandarins: “No other class combined their respect for, and grand vision of, the civilizing role of learning with their economic resources and the realism needed to put their plans into practice” (p. 113). Building on philosophical and historical elaboration, the book’s third part on achieving self-government discusses the six American moves leading to institutional innovation. At organizational level, the German chair and institute give way to departments and discipline, the university presi-dent is no longer figurehead but chief executive, and independent boards of trustees, not govern-ment officials, have ultimate authority. The implications for individuals and organizations of these “design shifts” cannot be overstated. Anyone seeking to understand American higher education, with its phenomenal vertical and horizontal differentiation and on-going academic drift (“a snake-like procession” as David Riesman, to whom the book is dedicated, calls it), and its self-organized autonomy—supported by many philanthropists without the limiting control of a few state bureau-crats—will find this analysis illuminating. Embedded in civil society, “vigorous self-government is the historic design contribution of the American university” (p. 209)—and an achievement that must be guarded in an era in which university autonomy is at risk. In concluding, Meyer’s American opti-mistic and laudatory tone shifts back to Germanic critique and foreboding, identifying challenges and the contemporary struggles that threaten the unintentional masterpiece of institutional learning and diversity. Such justified hopes and fears must now give way to empirical studies of the extraor-dinary outputs in terms of scientific production and societal capabilities and well-being brought about by the continuous process of university Bildung—in Germany, the United States, and around the world.

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.

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.
