Cette contribution a pour objet d'analyser l'importance des frontières nationales pour les identités spatiales dans des régions transfrontalières. À cet effet, elle élaborera un modèle d'analyse pluridimensionnel permettant d'étudier les identités et, à l'exemple de la Grande Région SaarLorLux, posera la question de savoir comment les habitants se représentent l'espace et organisent leurs pratiques de vie quotidienne sur le plan spatial. Par ailleurs, l'analyse révèlera des projections spatiales dans le discours politique et montrera dans quelle mesure celles-ci constituent une base de processus identitaires. La contribution démontre que, malgré des imbrications transfrontalières, les frontières nationales jouent un rôle important dans les processus de projection et d'appropriation identitaires des habitants de la Grande Région SaarLorLux, mais pas nécessairement en tant que catégories rigides.

The finite-time attitude synchronization problem is considered in this paper, where the rotation of each rigid body is expressed using the axis-angle representation. Two discontinuous and distributed controllers using the vectorized signum function are proposed, which guarantee almost global and local convergence, respectively. Filippov solutions and non-smooth analysis techniques are adopted to handle the discontinuities. Sufficient conditions are provided to guarantee finite-time convergence and boundedness of the solutions. Simulation examples are provided to verify the performances of the control protocols designed in this paper. [less ▲]

Modern enterprise systems can be composed of many web services (e.g., SOAP and RESTful). Users of such systems might not have direct access to those services, and rather interact with them through a single-entry point which provides a GUI (e.g., a web page or a mobile app). Although the interactions with such entry point might be secure, a hacker could trick such systems to send malicious inputs to those internal web services. A typical example is XML injection targeting SOAP communications. Previous work has shown that it is possible to automatically generate such kind of attacks using search-based techniques. In this paper, we improve upon previous results by providing more efficient techniques to generate such attacks. In particular, we investigate four different algorithms and two different fitness functions. A large empirical study, involving also two industrial systems, shows that our technique is effective at automatically generating XML injection attacks. [less ▲]

In order to achieve our objective, we will first provide an overview of the development of cooperation research, its characterizing orientations and establish a link to the topic of this contribution (chapter 2). The following presentation of practice theories introduces praxeological thinking and provides a condensed outline of the state of the art of this cultural sociological theory (chapter 3). Building on this, we will develop our idea of a cross-border practice formation that breaks with the premises of traditional cooperation research, and we provide an alternative perspectivation by outlining four challenges of CBC (chapter 4). In consideration of some research-practical particularities which are linked to the suggested analytical perspective, we eventually offer (chapter 5) an outlook on the development of an alternative research approach which is compatible within a multidisciplinary context.

Correctness of UML class diagrams annotated with OCL constraints can be checked using bounded verification techniques, e.g., SAT or constraint programming (CP) solvers. Bounded verification detects faults efficiently but, on the other hand, the absence of faults does not guarantee a correct behavior outside the bounded domain. Hence, choosing suitable bounds is a non-trivial process as there is a trade-off between the verification time (faster for smaller domains) and the confidence in the result (better for larger domains). Unfortunately, bounded verification tools provide little support in the bound selection process. In this paper, we present a technique that can be used to (i) automatically infer verification bounds whenever possible, (ii) tighten a set of bounds proposed by the user and (iii) guide the user in the bound selection process. This approach may increase the usability of UML/OCL bounded verification tools and improve the efficiency of the verification process. [less ▲]

With the advent of Industry 4.0, a growing number of sensors within modern production lines generate high volumes of data. This data can be used to optimize the manufacturing industry in terms of complex network topology metrics commonly used in the analysis of social and communication networks. In this work, several such metrics are presented along with their appropriate interpretation in the field of manufacturing. Furthermore, the assumptions under which such metrics are defined are assessed in order to determine their suitability. Finally, their potential application to identify performance limiting resources, allocate maintenance resources and guarantee quality assurance are discussed. [less ▲]

This paper examines literature reviews in 12 master’s dissertations written in German, English and French. Specifically, we analysed the discourse structure of 155 paragraphs to assess the extent to which students manage to write a coherent review combining literature reports with their own ‘voice’. The study was motivated by the design of a multilingual academic writing course at the University of Luxembourg Language Centre. The analysis distinguished three main discourse elements, nl. report, discussion and text orientation. The data reveal considerable variation in the frequency with which these combine to form different paragraph types. However, in all three languages, report discourse uses the same quotation and reformulation strategies and tends to employ ‘list’ structures with few cohesive links. Discussion elements are generally not elaborated and the writer’s voice is weak. Text organization uses the same linguistic strategies and is mainly used to orientate readers rather than to summarize or signal transitions. Pedagogical implications for multilingual academic writing courses are discussed. [less ▲]

Previous studies have almost consistently found differences between lower and higher educated voters regarding their policy congruence, the policy position agreement between voters and their party. This study analyses the role of a campaign herein. Based on novel panel evidence with an extensive battery of policy statements, combined with a survey of party leaders using the same items, we find that, more than the lowly educated, the highly educated profit from the campaign to increase their policy congruence. The reason for the increased inequality is that the later switch parties more often during the campaign than the former. Our evidence also suggests that the higher educated switch parties because this may increase their policy congruence. In sum, the campaign produces a Matthew effect. Those already having a higher policy congruence increase their congruence even further, while those with a lower congruence to start with, do not make any significant progress. [less ▲]

Decision-making impairments play a pivotal role in the emergence and maintenance of addictive disorders. However, a sound conceptualization of decision making as an umbrella construct, encompassing its cognitive, affective, motivational, and physiological subcomponents, is still lacking. This prevents an efficient evaluation of the heterogeneity of decision-making impairments and the development of tailored treatment. This paper thus unfolds the various processes involved in decision making by adopting a critical approach of prominent dual- or triadic-process models, which postulate that decision making is influenced by the interplay of impulsive-automatic, reflective-controlled, and interoceptive processes. Our approach also focuses on social cognition processes, which play a crucial role in decision making and addictive disorders but were largely ignored in previous dual- or triadic-process models. We propose here a theoretical framework in which a range of coordinated processes are first identified on the basis of their theoretical and clinical relevance. Each selected process is then defined before reviewing available results underlining its role in addictive disorders (i.e., substance use, gambling, and gaming disorders). Laboratory tasks for measuring each process are also proposed, initiating a preliminary process-based decision-making assessment battery. This original approach may offer an especially informative view of the constitutive features of decision making impairments in addiction. As prior research has implicated these features as risk factors for the development and maintenance of addictive disorders, our processual approach sets the scene for novel and transdiagnostic experimental and applied research avenues [less ▲]
