Die Auffassung, dass Grenzen aus sozialer Praxis hervorgehen und soziale Praxis hervorbringen, hat in den letzten Jahrzehnten für eine Reihe an Ansätzen und Begriffen gesorgt. Der Beitrag versucht diese zu systematisieren und stellt einen processual shift, multiplicity shift und complexitiy shift vor. Diese Trends beschreiben verschiedene analytische Schwerpunktsetzungen und eine zunehmend differenziertere Beschäftigung mit Grenzen. Abschließend wird auf die noch unzureichend bestimmte Kategorie der sozialen Praxis und auf das Potential der Praxistheorien für die Grenzforschung eingegangen. [less ▲]

Objective: Criterion A of the alternative model for the classification of personality disorders in the DSM-5 introduced the Level of Personality Functioning Scale (LPFS), a dimensional model for the assessment of impairments in self and interpersonal functioning. The LPFS was developed based on a review of different measures of personality functioning, such as the Reflective Functioning Scale, a measure of mentalizing. This study investigated the empirical overlap between LPFS and mentalization. Methods: The study sample included adult inpatients (n = 55) with a mental disorder and a healthy adult control group (n = 55). All participants were examined regarding the LPFS using the Semi-Structured Interview for Personality Functioning DSM-5 (STiP-5.1); mentalizing was assessed with the Brief Reflective Functioning Interview and coded with the Reflective Functioning Scale. We used structural equation modeling to investigate the relationship between LPFS domains and mentalization. Correlation analysis was used to examine the agreement between interview-rated LPFS and self-report measures of personality dysfunction. Results: All domains of the LPFS were significantly related to mentalizing. Interview-rated LPFS was significantly associated with self-reported personality dysfunction. Conclusion: The findings support the notion that the LPFS and mentalization share a strong conceptual and operational overlap by demonstrating that both constructs are empirically interrelated. The results yield further support for the validity of the LPFS as a dimensional model for the assessment of personality disorder severity. [less ▲]

ABSTRACT Video games as a consumer product have changed significantly with the advent of in-game purchasing systems (e.g., microtransactions, ‘loot boxes’). This review examines consumer protections related to in-game purchasing by anticipating some of the potential design strategies that might contribute to higher risk consumer behavior. Attention was directed towards the analysis of patents for potential in-game purchasing systems, with 13 identified on Google Patents. The design features were analysed in relation to the consumer rights and guarantees described in the terms of use agreements of the patent assignees. The analysis revealed that some in-game purchasing systems could be characterized as unfair or exploitative. These systems describe tactics that capitalize on informational advantages (e.g., behavioral tracking) and data manipulation (e.g., price manipulation) to optimize offers to incentivize continuous spending, while offering limited or no guarantees or protections (e.g., refund entitlement), with the potential to exploit vulnerable players (e.g., adolescents, problematic gamers). These findings are critically discussed in relation to behavioral economics, addiction psychology, and the clinical conceptualization of gaming disorder. Appropriate policy and consumer protection measures, psychologically informed interventions, and ethical game design guidelines are needed in order to protect the interests and wellbeing of consumers.

Under the General Data Protection Regulation (GDPR), transparency of information becomes an obligation aimed at creating an ecosystem where data subjects understand and control what happens to their personal data. The definition of transparency stresses its user-centric nature, while design considerations to comply with this obligation assume central importance. This article focuses on the icons established by the GDPR Art. 12.7 to offer “a meaningful overview of the intended processing”. Existing attempts to represent data protection through icons have not met widespread adoption and reasons about the strengths and weaknesses of their creation and evaluation are here discussed. Building on this analysis, we present an empirical research proposing a new icon set that responds to GDPR requirements. The article also discusses the challenges of creating and evaluating such icon set and provides some future directions of research for effective an effective implementation and standardization.

Reducing pollutant emissions and promoting sustainable mobility solutions, including Public Transport (PT), are increasingly becoming key objectives for policymakers worldwide. In this work we develop an optimal vehicle scheduling approach for next generation PT systems, considering the instance of mixed electric / hybrid fleet. Our objective is that of investigating to what extent electrification, coupled with optimal fleet management, can yield operational cost savings for PT operators. We propose a Mixed In- teger Linear Program (MILP) to address the problem of optimal scheduling of a mixed fleet of electric and hybrid / non-electric buses, coupled with an ad-hoc decomposition scheme aimed at enhancing the scalability of the proposed MILP. Two case studies arising from the PT network of the city of Luxem- bourg are employed in order to validate the model; sensitivity analysis to fleet design parameters is performed, specifically in terms of fleet size and fleet composition. Conclusions point to the fact that careful modelling and handling of mixed-fleet conditions are necessary to achieve operational savings, and that marginal savings gradually reduce as more conventional buses are replaced by their electric counterparts. We believe the methodology proposed may be a key part of advanced decision support systems for policymakers and operators that are dealing with the on-going transition from conventional bus fleets towards greener transport solutions.

This paper examines the political economy and law of bank resolution in the case of Italy—specifically its treatment of three failing banks that were resolved in 2016/2017—Monte de Paschi, Veneto and Vicenza banks. These three cases stand out for the relatively large degree of discretion exercised by national resolution and state aid authorities, ultimately with the permission of their European counterparts. This paper examines the motivations driving Italian authorities to lobby the Commission for leeway in applying the Bank Recovery and Resolution Directive, and analyses the intricacies of the legal framework to underline the extent of discretion exercised by policy makers. It concludes that the discretion visible in these three cases is not (entirely) contained within EU law, and that bending the law or turning a blind eye to infractions was key to understanding the EU approach to Italy.

The verification of complex software systems often requires to check quantitative properties that rely on aggregation operators (e.g., the average response time of a service). One way to ease the specification of these properties is to use property specification patterns, such as the ones for “service provisioning”, previously proposed in the literature. In this paper we focus on the problem of performing offline trace checking of temporal properties containing aggregation operators. We first present TemPsy-AG, an extension of TemPsy—an existing pattern-based language for the specification of temporal properties—to support service provisioning patterns that use aggregation operators. We then extend an existing model-driven procedure for trace checking, to verify properties expressed in TemPsy-AG. The trace checking procedure relies on the efficient mapping of temporal properties written in TemPsy-AG into OCL constraints on a meta-model of execution traces. We have implemented this procedure in the TemPsy-Check-AG tool and evaluated its performance: our approach scales linearly with respect to the length of the input trace and can deal with much larger traces than a state-of-the-art tool.

We study the effects of Chapter 11 bankruptcy protection on competitive product pricing in both domestic and international markets using data from the airline industry. We find a decline of about 5% in domestic markets and an even more significant drop in international markets. Further, in international markets the competing carriers respond by dropping their prices as well, whereas they slightly increase them domestically. By contrast, existing literature considers only domestic markets finding a more moderate fare drop of about 3% in domestic markets by the bankrupt carrier, with mixed results on the fare drop by competitors.

We investigate the impact of corruption on tax compliance using a sample of 700 small business in Bamako, Mali. The main contribution of this paper is to focus on micro-enterprises (including semi-formal and informal ones), while existing works concentrate on large and formal firms. Our results show that (i) even very small firms pay taxes (two-thirds of firms pay taxes in our sample); and, (ii) paying bribes reduces significantly tax compliance. This latter finding is robust (i) to the addition of a set of control variables accounting for other determinants, (ii) to treatment for endogeneity, and (iii) the use of a different proxy for tax compliance.

Early life adversity (ELA) has been associated with inflammation and immunosenescence, as well as hyporeactivity of the HPA-axis. As the immune system and HPA-axis are tightly intertwined around the glucocorticoid receptor (GR) we examined peripheral GR functionality in the EpiPath cohort, where participants had either been exposed to ELA (separation from parents and/or institutionalization followed by adoption) (n=40) or had been reared by their biological parents (n=72). Expression of the strict GR target genes FKBP5 and GILZ as well as total and 1F and 1H GR transcripts were similar between groups. Furthermore, there were no differences in GR sensitivity, examined by the effects of dexamethasone on IL6 production in LPS-stimulated whole blood. Although we did not find differences in methylation at the GR 1F exon or promoter region, we identified a region of the GR 1H promoter (CpG 1-9) that showed lower methylation levels in ELA. Peripheral GR signaling was unperturbed in our cohort and the observed immune phenotype does not appear to be secondary to an altered glucocorticoid receptor response to glucocorticoids. To identify signaling pathways that may underlie the ELA immune phenotype, future research should focus on unbiased approaches, such as investigating whole genome methylation profiles. [less ▲]

Background: Parental divorce has been associated with reduced well-being in young adults. It is, however, unclear whether this finding is clinically relevant as studies using structural clinical interviews are missing. This study, therefore, investigated if young adults with divorced parents are at risk to develop mental disorders. Furthermore, differences in parental care, social connectedness, chronic stress and traumatic experiences between children of divorced and non-divorced parents were investigated. Methods: 121 women (mean age: 23 years) were interviewed using the Structured Clinical Interview for DSMIV Axis I (i.e., major mental disorders) and II (i.e., personality disorders) Disorders and asked to complete questionnaires assessing parental care, social connectedness (loneliness, attachment anxiety and avoidance), chronic stress, childhood trauma and depression. Results: Young adults of divorced parents had a higher risk for Axis I but not Axis II disorders as compared to young adults of non-divorced parents. Participants from divorced families as compared to non-divorced families reported more depression, loneliness, childhood trauma, attachment avoidance, attachment anxiety, chronic stress and less parental care. Limitations: Due to the cross-sectional design of this study, conclusions about causality remain speculative. Conclusion: The increased vulnerability of children of divorced parents to develop mental disorders, and to experience more chronic stress, loneliness, attachment avoidance, attachment anxiety, and traumatic experiences during childhood is alarming and highlights the importance of prevention programs and psycho-education during the process of parental divorce. Parental support with regard to adequate caregiving is needed to help parents to better support their children during and after their divorce. [less ▲]

Introduction Diabetes mellitus prevalence is estimated between 3.1% and 4.3% in Rwanda. To address non-communicable diseases and the shortage of health workforce, the Rwandan Ministry of Health has introduced Home-Based Care Practitioners (HBCPs): laypeople provide longitudinal care to chronic patients after receiving a six-month training. Leveraging technological mobile solutions may also help improve health and health care. The D²Rwanda study aims at: a) determining the efficacy of an integrated programme for the management of diabetes in Rwanda, which will provide monthly patient assessments by HBCPs, and an educational and self-management mHealth patient tool, and; b) exploring qualitatively the ways the interventions will have been enacted, their challenges and effects, and changes in the patients’ health behaviours and HBCPs’ work satisfaction. Methods and analysis This is a mixed methods sequential explanatory study. Firstly, there will be a one-year cluster randomised controlled trial including two interventions [(1) HBCPs programme; (2) HBCPs programme + mobile health application] and usual care (control). Currently, nine hospitals run the HBCPs programme. Under each hospital, administrative areas implementing the HBCPs programme will be randomised to receive intervention 1 or 2. Eligible patients from each area will receive the same intervention. Areas without the HBCPs programme will be assigned to the control group. The primary outcome will be changes in HbA1c. Secondary outcomes include medication adherence, mortality, complications, health-related quality of life, diabetes-related distress and health literacy. Secondly, at the end of the trial, focus group discussions will be conducted with patients and HBCPs. Financial support was received from the Karen Elise Jensens Fond, and the Universities of Aarhus and Luxembourg. Ethics and dissemination Ethics approval was obtained from the Rwanda National Ethics Committee and the Ethics Review Panel of the University of Luxembourg. Findings will be disseminated via peer-reviewed publications and conference presentations. Clinical trial registration NCT03376607 [less ▲]

Purpose of Review The 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) categorizes gambling disorder in the section on substance-related and addictive disorders, and the 11th revision of the International Classification of Diseases (ICD-11) includes both gambling and gaming disorder as disorders due to addictive behaviors. However, there is less evidence for other putative behavioral addictions. This review focuses on requirements for epidemiological studies of disorders that may be considered as behavioral addictions and compares the current state of research with principles of sound epidemiological research. Recent Findings In studies of behavioral addictions, samples are often quite small, which may lead to increased random error. The lack of sound assessment tools—particularly the lack of agreed-upon diagnostic criteria and standardized diagnostic interviews—may also increase systematic error. Other concerns related to systematic bias include the use of convenience samples, lack of pro-active recruitment, inadequate assessment of confounding variables, and a dearth of representative and longitudinal studies. Summary This review recommends that future studies of putative behavioral addictions should more closely adhere to methodological standards of epidemiological research to reduce random and systematic error. Specific recommendations are detailed to advance epidemiological research in this area with the aim of improving the evidence base and generating more refined public health recommendations and policies.

Long-term behaviour of concrete structural elements is very important for evaluation of its health and serviceability range. The phenomena that must be considered are complex and lead to coupled multiphysics formulations. Such formulations are difficult not only from physical perspective, but also from computational perspective. In this contribution attention to computational efficiency and effective implementation is payed. Presented model for concrete ageing is based on microprestress-solidification (MPS) theory of Bazant [1], Kunzel’s model for heat and moisture transport [2] and Mazars model for damage [3]. Ageing linear viscoelastic response, which is immanent to MPS theory and concrete creep, leads to ordinary differetial equation for internal variables solved for every quadrature/nodal point. Numerical structure of the finite element discretisation is examined. Few simplifications on physical model lead to a very efficient linear algebra problem for which standard preconditioned Krylov solvers are reviewed. In parallel, weak and strong scaling tests are performed. All results are produced within open-source finite element framework FEniCS [4]. These models are usually a basis for more involved thermo-hygro-chemo-mechanical (THCM) models with migrating chemical species. It is anticipated, that presented results will help practitioners or other structural engineerers with the choice of suitable and efficient methods for long-term concrete modeling. [less ▲]
