[more ▼] 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.

[more ▼] A computer-formalisation of the essential parts of Fitting's textbook "Types, Tableaus and Gödel's God" in Isabelle/HOL is presented. In particular, Fitting's (and Anderson's) variant of the ontological argument is verified and confirmed. This variant avoids the modal collapse, which has been criticised as an undesirable side-effect of Kurt Gödel's (and Dana Scott's) versions of the ontological argument. Fitting's work is employing an intensional higher-order modal logic, which we shallowly embed here in classical higher-order logic. We then utilize the embedded logic for the formalisation of Fitting's argument. (See also the earlier AFP entry ``Gödel's God in Isabelle/HOL''.)

[more ▼] 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 ▲] Detailed reference viewed: 85 (5 UL)![]() Pelard, Emmanuelle ![]() in Nouvelles Francographies.

[more ▼] 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.

[more ▼] 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.

[more ▼] The suppressors of cytokine signaling (SOCS) are negative feedback inhibitors of cytokine and growth factor-induced signal transduction. The C-terminal SOCS box region is thought to regulate SOCS protein stability most likely via an elongin C interaction. In the present study, we have found that phosphorylation of SOCS3 at two tyrosine residues in the conserved SOCS box, Tyr204 and Tyr221, can inhibit the SOCS3-elongin C interaction and activate proteasome-mediated SOCS3 degradation. Jak-mediated phosphorylation of SOCS3 decreased SOCS3 protein half-life, and phosphorylation of both Tyr204 and Tyr221 was required to fully destabilize SOCS3. In contrast, a phosphorylation-deficient mutant of SOCS3, Y204F,Y221F, remained stable in the presence of activated Jak2 and receptor tyrosine kinases. SOCS3 stability correlated with the relative amount that bound elongin C, because in vitro phosphorylation of a SOCS3-glutathione S-transferase fusion protein abolished its ability to interact with elongin C. In addition, a SOCS3/SOCS1 chimera that co-precipitates with markedly increased elongin C, was significantly more stable than wild-type SOCS3. The data suggest that interaction with elongin C stabilizes SOCS3 protein expression and that phosphorylation of SOCS box tyrosine residues disrupts the complex and enhances proteasome-mediated degradation of SOCS3.

[more ▼] Rare earth elements govern today’s high-tech world and are deemed to be essential for the attainment of sustainable development goals. Since the 1990s, these elements have been predominantly supplied by one single actor, China. However, due to the increasing relevance of their availability, the United States, who imports 80% of its rare earths from China, recently announced its plan to (re-)enter the rare earths supply market. This paper analyzes the strategic interactions among these two countries in open-loop and Markovian strategy spaces. Particular interest is devoted to the impact of heterogeneous supply concepts on (1) the theoretical optimal timing for the U.S. to enter the non-renewable resource market, (2) China’s optimal supply reaction to the U.S.’ entry announcement, (3) the central planner outcome, and (4) the profitability of the suppliers’ extraction behavior. By setting up a continuous-time differential game model, we show that in the absence of arbitrage opportunity, (1) the U.S. should always postpone the production launch until its rare earths reserves coincide with those of China, (2) China’s monopolistic supply is not shaped by the selected strategy, (3) while the duopolistic Markovian behavior is initially more lucrative than open-loop commitment, the opposite situation emerges as the competition proceeds, and (4) on balance, both countries are financially better off when committing to an open-loop supply path.

[more ▼] This work aims to develop a novel Cross-Entropy (CE) optimization-based fuzzy controller for Unmanned Aerial Monocular Vision-IMU System (UAMVIS) to solve the seeand-avoid problem using its accurate autonomous localization information. The function of this fuzzy controller is regulating the heading of this system to avoid the obstacle, e.g. wall. In the Matlab Simulink-based training stages, the Scaling Factor (SF) is adjusted according to the specified task firstly, and then the Membership Function (MF) is tuned based on the optimized Scaling Factor to further improve the collison avoidance performance. After obtained the optimal SF and MF, 64% of rules has been reduced (from 125 rules to 45 rules), and a large number of real flight tests with a quadcopter have been done. The experimental results show that this approach precisely navigates the system to avoid the obstacle. To our best knowledge, this is the first work to present the optimized fuzzy controller for UAMVIS using Cross-Entropy method in Scaling Factors and Membership Functions optimization.
