Overall, the preliminary results of the representative survey of adolescents and young adults in Luxembourg paint a complex picture. In general, young people seem to be aware of their responsibility to contain the coronavirus. The majority have the necessary information and opportunities to act in a way that reflects this responsibility. There are suggestions of negative impacts stemming from COVID-19 and measures to combat COVID-19, but these do not appear to be the prevailing dynamic at the time of completing the survey. However, it is likely that negative effects will increase the longer the COVID-19 pandemic lasts and the more individual and social resources are depleted. There are already detectable beginnings of sociodemographic and socioeconomic differences in how people are coping with the COVID-19 pandemic. It is therefore important to continue to provide young people with support for mastering the transition between childhood and adulthood despite COVID-19 and to responsibly provide them with the opportunities and spaces this requires. This process must pay particular attention to inequalities that are developing and being reinforced. [less ▲]

Student response systems as an active learning strategy have shown to be useful in different study domains. With the advent of gamification, these environments have become very popular to improve student engagement. However, existing solutions only provide a static set of activity types and limit their use to classrooms. In this paper, we present Yactul, an extensible game-based student response framework for active learning. Our ecosystem fosters continuous learning both in the collaborative setting of the classroom and the private study environment of the student. Our modular architecture enables a seamless integration of activities from a broad and extensible set. In addition, a mobile app for offline learning extends the experience outside the classroom and allows to replay quizzes anywhere and anytime, track the progress of an individual learner and suggest activities on topics that require more studying.

Background: Anaerobic digestion (AD) is a microbe-driven process of biomass decomposition to CH4 and CO2. In addition to renewable and cost-effective energy production, AD has emerged in the European Union as an environmentally friendly model of bio-waste valorisation and nutrient recycling. Nevertheless, due to the high diversity of uncharacterised microbes, a typical AD microbiome is still considered as "dark matter". Results: Using the high-throughput sequencing of small rRNA gene, and a monthly monitoring of the physicochemical parameters for 20 different mesophilic full-scale bioreactors over 1 year, we generated a detailed view of AD microbial ecology towards a better understanding of factors that influence and shape these communities. By studying the broadly distributed OTUs present in over 80% of analysed samples, we identified putatively important core bacteria and archaea to the AD process that accounted for over 70% of the whole microbial community relative abundances. AD reactors localised at the wastewater treatment plants were shown to operate with distinct core microbiomes than the agricultural and bio-waste treating biogas units. We also showed that both the core microbiomes were composed of low (with average community abundance </= 1%) and highly abundant microbial populations; the vast majority of which remains yet uncharacterised, e.g. abundant candidate Cloacimonetes. Using non-metric multidimensional scaling, we observed microorganisms grouping into clusters that well reflected the origin of the samples, e.g. wastewater versus agricultural and bio-waste treating biogas units. The calculated diversity patterns differed markedly between the different community clusters, mainly due to the presence of highly diverse and dynamic transient species. Core microbial communities appeared relatively stable over the monitoring period. Conclusions: In this study, we characterised microbial communities in different AD systems that were monitored over a 1-year period. Evidences were shown to support the concept of a core community driving the AD process, whereas the vast majority of dominant microorganisms remain yet to be characterised. [less ▲]

Invasion of surrounding brain tissue by isolated tumor cells represents one of the main obstacles to a curative therapy of glioblastoma multiforme. Here we unravel a mechanism regulating glioma infiltration. Tumor interaction with the surrounding brain tissue induces CD95 Ligand expression. Binding of CD95 Ligand to CD95 on glioblastoma cells recruits the Src family member Yes and the p85 subunit of phosphatidylinositol 3-kinase to CD95, which signal invasion via the glycogen synthase kinase 3-beta pathway and subsequent expression of matrix metalloproteinases. In a murine syngeneic model of intracranial GBM, neutralization of CD95 activity dramatically reduced the number of invading cells. Our results uncover CD95 as an activator of PI3K and, most importantly, as a crucial trigger of basal invasion of glioblastoma in vivo. [less ▲]

Based on the assumptions of social cognitive theory and self-regulation theory, the present study aimed at exploring psychosocial factors in self-care of diabetes (Edgar & Skinner, 2003; Iannotti et al., 2006; Nouwen et al., 2009). The study sample comprised N 1⁄4 99 patients with type 1 diabetes aged between 12 and 39 years. Participants completed the diabetes self-efficacy scale, the brief illness perceptions questionnaire, the WHO-five index and the summary of diabetes self-care activities scale. Results showed that illness perceptions (i.e. perceived consequences (r1⁄4􏰆0.28), personal control (r1⁄40.24), treatment control (r1⁄40.27), compre- hension (r1⁄40.27) and emotional response (r1⁄40.27)), as well as well-being (r1⁄40.42) and perceived diabetes self-efficacy (r 1⁄4 0.55) were significantly correlated with self-care. Furthermore, stepwise regression analyses elucidated self-efficacy (􏰈1⁄40.44) to be the most powerful predictor of self-care, as illness perceptions and well-being became non significant when introducing self-efficacy. Moreover, self-efficacy completely mediated the effect of well- being on self-care (Sobel t 1⁄4 3.74, p50.01). As for clinical implications of these results, it can be suggested that a stronger emphasise should be given on fostering patients’ confidence in their ability to effectively manage their diabetes.

Political debates offer a rare opportunity for citizens to compare the candidates’ positions on the most controversial topics of the campaign. Thus they represent a natural application scenario for Argument Mining. As existing research lacks solid empirical investigation of the typology of argument components in political debates, we fill this gap by proposing an Argument Mining approach to political debates. We address this task in an empirical manner by annotating 39 political debates from the last 50 years of US presidential campaigns, creating a new corpus of 29k argument components, labeled as premises and claims. We then propose two tasks: (1) identifying the argumentative components in such debates, and (2) classifying them as premises and claims. We show that feature-rich SVM learners and Neural Network architectures outperform standard baselines in Argument Mining over such complex data. We release the new corpus USElecDeb60To16 and the accompanying software under free licenses to the research community. [less ▲]

Properly benchmarking Automated Program Repair (APR) systems should contribute to the development and adoption of the research outputs by practitioners. To that end, the research community must ensure that it reaches significant milestones by reliably comparing state-of-the-art tools for a better understanding of their strengths and weaknesses. In this work, we identify and investigate a practical bias caused by the fault localization (FL) step in a repair pipeline. We propose to highlight the different fault localization configurations used in the literature, and their impact on APR systems when applied to the Defects4J benchmark. Then, we explore the performance variations that can be achieved by "tweaking'' the FL step. Eventually, we expect to create a new momentum for (1) full disclosure of APR experimental procedures with respect to FL, (2) realistic expectations of repairing bugs in Defects4J, as well as (3) reliable performance comparison among the state-of-the-art APR systems, and against the baseline performance results of our thoroughly assessed kPAR repair tool. Our main findings include: (a) only a subset of Defects4J bugs can be currently localized by commonly-used FL techniques; (b) current practice of comparing state-of-the-art APR systems (i.e., counting the number of fixed bugs) is potentially misleading due to the bias of FL configurations; and (c) APR authors do not properly qualify their performance achievement with respect to the different tuning parameters implemented in APR systems.

Social service providers in the Greater Region report that many children in need of special care and social assistance find themselves in cross-border situations. The legal regulations and practices for the care of children and adolescents can vary considerably from country to country. This can cause delays, breaks or deterioration in the quality of support and sometimes irreversibly worsen the child's situation. Depending on the situation, diagnoses and access to social, medical-social or legal services can change considerably. The EURQUA project deals with cross-border child protection and disability rights within a multinational perspective. [less ▲]
