This paper presents a methodology for comparing income rank volatility profiles over time and across distributions. While most of the existing measures are affected by changes in marginal distributions, this paper proposes a framework that is based on individuals’ relative positions in the distribution, and is neutral in relation to structural changes that occur in the economy. Applying this approach to investigate rank volatility in Germany and the US over three decades, we show that while poorer individuals within both countries are the most volatile, the volatility trend for the middle class in each of these countries differs.

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 ▲]

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.

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 ▲]

The European Union is a union under the rule of law and accordingly all exercise of public authority needs to conform with the principle of legality. The legal framework of the EU is, however, as much as that of any state or international organization, subject to change over time. That part of this legal framework specifically governing EU administration has been particularly dynamic. The central reason for this dynamism is to be found in the evolving nature of European integration, and in the changing requirements and conditions for implementing EU policies. The legal framework of administration has been both the subject of, and a response to, change in the ambient political and institutional environment. The EU, having started as an organization of six Member States focused on economic integration, has evolved into a Union of twenty-seven Member States now touching almost all elements of the exercise of public power in a modern society. The evolutionary development of the constitutional basis of EU law, with its many phases of Treaty reforms and change induced by case-law, finds its parallel in EU administrative law. European administrative law has in this process grown, changed, and indeed matured over time, and has emerged as an important, yet sometimes not well understood, factor which materially shapes policy in the EU and its achievement in reality. The rise of the importance of EU administrative law is itself attributable both to the specificities of European integration and to the general increase in the importance of administrative regulation in the past decades. On the one hand, the protection of the society against risks associated with private activity such as banking, food production, energy production and distribution, transport, or activities threatening to the environment, to name just a few, and the achievement of a balance between their benefits and dangers have become increasingly important subjects of attention. On the other hand, the provision of services and infrastructure necessary to ensure and protect basic standards of living such as pensions, health care, access to water, energy supply and telecommunications services have been the subject of mixed regimes, often still having a strong public service element, but increasingly left to private provision subject to various levels of market regulation. Both kinds of motivation for regulatory measures and their implementation by appropriate authorities have added to, and substantially changed, the broad character of public administration in Europe in recent decades. Such changes have occurred not just on a national, that is, Member State level, but also, pre-eminently, on the level of the European Community and now Union. Indeed, many of the changes have themselves been triggered on the European level as integral or at least adjuvant elements of the establishment of the European internal market. The role, then, of administrative law and administrative activity on the European level is extensive and important. Rules and principles governing the exercise of administrative functions, the organization of the institutions and bodies exercising these functions, and applicable procedures are the essence of EU administrative law. These are the subject of this book. There are, it must be observed, many perspectives from which one can view, analyse and comprehend both administration and administrative law. Three models or perspectives appear to us to be particularly helpful: administration and administrative law may be usefully considered from functional, organizational, and procedural standpoints. The functional aspect of administration refers to the totality of the tasks of administration, no matter who undertakes them and how they are carried out. The organizational perspective emphasises the organization and structure of the institutions, bodies, and actors engaged in undertaking such tasks. Finally, a procedural understanding of administration observes the processes which link the various actors and authorities in the performance of administrative functions. None of these models standing alone provides a fully rounded understanding or conceptualisation of the subject matter of the book. A proper analysis of EU administrative law cannot view it from only one of these perspectives. Taken together, however, these three standpoints do offer a comprehensive perception, giving the subject a more multi-dimensional shape, and thus allowing a more tractable presentation of what is very complex material. For this reason, we offer a discussion of each of these three perspectives — the functional, organizational, and procedural aspects of European Union administration and the associated legal framework — by way of introduction. The three models are, of course, closely interlinked and in reality scarcely separable but, for analytical and presentational clarity, they are here addressed separately. [less ▲]

The aim of this contribution is to explain in a straightforward manner how Bayesian inference can be used to identify material parameters of material models for solids. Bayesian approaches have already been used for this purpose, but most of the literature is not necessarily easy to understand for those new to the field. The reason for this is that most literature focuses either on complex statistical and machine learning concepts and/or on relatively complex mechanical models. In order to introduce the approach as gently as possible, we only focus on stress-strain measurements coming from uniaxial tensile tests and we only treat elastic and elastoplastic material models. Furthermore, the stress-strain measurements are created artificially in order to allow a one-to-one comparison between the true parameter values and the identified parameter distributions. [less ▲]

Preliminary evidence suggests that childhood maltreatment is associated with higher problematic social media use (PSMU). It has also been established that childhood emotional maltreatment (CEM) is associated with body image dissatisfaction (BID). However, the direct and indirect impacts of CEM on PSMU via BID remain untested. The present study examined these direct and indirect relationships among a sample of 385 adolescents (mean age 15.62 years, range 14–18 years). Results indicated that female adolescents had higher levels of CEM, BID, and PSMU compared to males. Structural equation modeling indicated that CEM was indirectly associated with PSMU via BID among males. However, only BID was positively associated with PSMU among females. The findings are in accordance with theoretical models suggesting that individuals’ core characteristics including early childhood experiences and psychopathological factors are associated with different types of specific internet-use disorders.
