According to the UML Standard 2.0 class and sequence diagrams are defined in a descriptive way by a MOF meta-model and semi-formal constraints. This paper presents a formal and constructive definition of the abstract syntax of UML class and sequence diagrams based on the well-defined theory of typed attributed graph transformation with inheritance and application conditions. The generated language covers all important features of these parts of UML diagrams and is shown to satisfy all of the corresponding constraints by construction. An explicit model transformation demonstrates the close correspondence between the graph grammar and the MOF definition of UML class and sequence diagrams. The graph grammar is validated by well-established benchmarks showing that all important features of the MOF definition of UML are covered. This formal constructive syntax definition of UML class and sequence diagrams is the basis for syntax directed editing, formal analysis, formal operational and denotational semantics and correctness of model transformations.

Types of health-related behaviours: a cluster analysis of the Luxembourgish HBSC data

Background: Although it is known that health behaviours, socio-demographic variables and outcomes correlate, it is rarely investigated if there are typical patterns of these variables among the research subjects. Objectives: To find out whether the students can be divided into distinct groups based on their health behaviour and whether these groups differ in other ways (outcomes and socio-demographics). Method: In step 1, a hierarchical cluster analysis was carried out to determine the number of groups and to identify the cluster centres. In step 2, this information was entered as the initial values of a cluster centre analysis. In step 3, the clusters were characterised using additional variables. Results: The 8065 students surveyed could be divided into 5 distinct groups based on their data on smoking, drinking, soft drinks, exercising, fighting and bullying, with cluster 1 and cluster 5 representing the strongest contrast. Cluster 1 comprises students whose health behaviour is generally positive. It is the largest cluster with 49.5% of students. Cluster 5 comprises students whose behaviour is consistently negative. It is the smallest cluster with 7.1% of students. Students in cluster 2 are close to average on many variables, but their dental health is problematic because they frequently consume soft drinks and rarely brush their teeth. Students in cluster 3 are physically inactive, their mental health is poor, but they are also rarely injured. The students in cluster 4 stand out because of their aggressive behaviour. Conclusion: With the help of cluster analysis, it is possible to categorise the students into a small number of groups based on their health behaviour. These groups are coherent in terms of health behaviour, many outcome variables and socio-demographic variables. [less ▲]

A Typical Case Report: Internet Gaming Disorder Psychotherapy Treatment in Private Practice

Background: Online or internet gaming disorder (IGD) is currently not recognized as a mental disorder in the actual Diagnostic and Statistical Manual of Mental Disorders (DSM-5), although it is an emerging disease. Non-substance-related addictions often have similarities with substance addictions. It is therefore important to have a good understanding of the client but also to have a good endurance. Due to the rise of e-sports, there is an anticipated and therefore possible trend to have many more patients with a non-substance addiction. There are many parallels, for instance tolerance, withdrawal and social problems, resulting from an increasing investment of time spent on the internet. Case presentation: To reduce possible inhibition in treating a patient with IGD, we present a case of a 19-year-old adolescent man who exhibited IGD and showed social problems associated with his addiction. Conclusions: This paper shows the importance and the effects of treating a non-substance addiction with cognitive behavioral therapy (CBT). After having successfully coped with an addiction, several shifts in addiction were often reported. In this case, no shifts were reported. The absence of such shifts makes our case a distinct and unique case. This is not a multimorbidity case, and that is the reason why we think this is an excellent example to show what we achieved, how we achieved it, and what we could establish. Of course, additional research and manuals are urgently needed. [less ▲]

A “Typus” as an Appropriate Legal Tool for the interpretation of the “No Bail-out” Clause: The 'Private Investor Principle'

The purpose of this paper is to present the academic debate on the interpretation of Article 125 TFEU and to critically demonstrate the jurisprudential controversy that surrounds this provision, both from the CJEU standpoint as well as the Bundesverfassungsgericht’s angle. While we believe that the Court interpreted rightly the provision at issue, we argue that it has left certain questions unanswered. The second part of the paper will develop our suggestion regarding the need to construct and adopt a ‘typus’, along the lines and by analogy to the ‘private investor principle’, as an appropriate form of legal reasoning for the interpretation of the ‘no bail-out clause’ proviso, that would allow more legal certainty as to the persisting question of what kind of financial assistance meets the purpose of Article 125 TFEU.

THE ‘TYRANNY OF THE LINE’: CITY PLANNING IN COLONIAL PHNOM PENH, 1860s – 1940s

THE ‘TYRANNY OF THE LINE’: CITY PLANNING IN COLONIAL PHNOM PENH, 1860s – 1940s. Thomas Kolnberger Université du Luxembourg, FLSHASE (Faculty of Language and Literature, Humanities, Arts and Education), Research Unit IPSE (Identités.Politique.Sociétés.Espaces), Campus Walferdange, Route de Diekirch (B.P.2), L-7201 Walferdange, Luxemburg This paper aims to highlight the role and influence of both ‘colonizer’ and ‘colonized’ on place and space. Their specific purposes are part of a process of mise-en-valeur of the French colonial regime on the one side and indigenous commodification of city space, examined here as a form of “bandwagoning”, on the other side. Cities in general are disputed places with regard to questions of urban development, planning and social control. Colonial cites in particular became central places for steering and enhancing the productivity of the entire colonial society. Thus, new urban structures were designed to house the agencies of an unequal relationship. The production of this particular space, however, was at no time a purely top-down process, imposed by the ‘colonizer’ on the ‘colonized’. In the very moment of the foundation of the colonial town, indigenous actors took the city as an opportunity, as a “structure and agency” for pursuing their very own interests. Colonial Phnom Penh is a good example to review these interactive processes under the following aspects: - ‘clash of civilizations’: Traditional French and Khmer linear planning as rivaling ‘top-down’ processes in a shared town - ‘grass-root urban planning’: The ‘bottom-up’ production of space of the indigenous city dwellers - ‘tyranny of the line’: The “social engineering” of the colonial city by land rents, building codes and regulations as grid squares The study is based on historical-critical analysis of archival sources in Cambodia (National Archives of Cambodia, Phnom Penh) and France (National Overseas Archives of France, Aix-en-Provence) with a focus on public works, maps, and photos.
