Im vorliegenden Bericht werden die aktuellen Befunde der Evaluation der Schulung BEE SECURE aus dem Jahr 2016/17 dargestellt. Die Schulung zur Förderung der Medienkompetenz wurde in diesem Jahr an 144 Grund- und Sekundarschulen in Luxemburg durchgeführt. Im Anschluss an die Schulung wurden jeweils von den Trainern, die die Schulung gehalten hatten und von den Schülern und deren Lehrern Fragebögen ausgefüllt. Somit lagen die Daten von 739 Trainerfragebögen, 768 Lehrerfragebögen und 10062 Schülerfragebögen dem Evaluationsdatensatz zugrunde. Der Lehrerfragebogen beinhaltete verschiedene Aussagen zur Effektivität der Schulung und zur Durchführung der Schulung. Es zeigte sich, dass die Lehrer sowohl mit der Effektivität als auch der Durchführung zufrieden bis sehr zufrieden waren. Die Auswertung der Trainerfragebögen zeigte, dass sie mit den meisten Aspekten des Trainings zufrieden waren. Besonders positiv wurden die Disziplin, das Klassenklima, die Lehrkräfteeinbindung sowie die Organisation bewertet. Weniger positiv wurde der Wissenstand der Schüler im Bezug auf das Internet und die Erfahrungsberichte der Schüler wahrgenommen. In Bezug auf die Schülerdaten zeigte sich, dass knapp über die Hälfte der Schüler bereits schon mal an einer BEE SECURE Schulung teilgenommen hatten. Alle abgefragten Aspekte des Trainings wurden von den Schülern durchweg als sehr positiv eingeschätzt. [less ▲]

Cent et une années, jour pour jour, après l’adoption de la première loi organisant le régime des sociétés commerciales au Grand-Duché du Luxembourg, la loi du 10 août 2016 portant modernisation de la loi du 10 août 1915 concernant les sociétés commerciales achève l’important effort de réforme dans lequel s’est lancé le gouvernement luxembourgeois avec l’aide du Laboratoire de droit économique de l’Université du Luxembourg. La loi sur les sociétés commerciales en sort renforcée, son orientation délibérément contractuelle confirmée et la sécurité juridique des montages sociétaires assurée. Fruit des contributions présentées par les auteurs de la réforme et des praticiens chevronnés lors du colloque organisé par la Faculté de Droit, d’Économie et de Finance et le barreau du Luxembourg, le présent ouvrage apporte une éclairage approfondi sur l’ensemble des nouvelles dispositions et constitue la référence pour en connaître tous les détails.

In this paper, we propose a framework for guiding patients and/or users in how to correct their posture in real-time without requiring a physical or a direct intervention of a therapist or a sports specialist. In order to support posture monitoring and correction, this paper presents a flexible system that continuously evaluates postural defects of the user. In case deviations from a correct posture are identified, then feedback information is provided in order to guide the user to converge to an appropriate and stable body condition. The core of the proposed approach is the analysis of the motion required for aligning body-parts with respect to postural constraints and pre-specified template skeleton poses. Experimental results in two scenarios (sitting and weight lifting) show the potential of the proposed framework. [less ▲]

The use of multi-criteria decision analysis (MCDA) by online broker to rank different service providers in the Cloud is based upon criteria provided by a customer. However, such ranking is prone to bias if the customer has insufficient domain knowledge. He/she may exclude relevant or include irrelevant criterion termed as ’misspecification of criterion’. This causes structural uncertainty within the MCDA leading to selection of suboptimal service provider by online broker. To cater such issue, we propose a self-regulated MCDA, which uses notion of factor analysis from the field of statistics. Two QoS based datasets were used for evaluation of proposed model. The prior dataset i.e., feedback from customers, was compiled using leading review websites such as Cloud Hosting Reviews, Best Cloud Computing Providers, and Cloud Storage Reviews and Ratings. The later dataset i.e., feedback from servers, was generated from Cloud brokerage architecture that was emulated using high performance computing (HPC) cluster at University of Luxembourg (HPC @ Uni.lu). The results show better performance of proposed model as compared to its counterparts in the field. The beneficiary of the research would be enterprises that view insufficient domain knowledge as a limiting factor for acquisition of Cloud services. [less ▲]

Breaches in online contracts (Service Level Agreements, SLAs) are usually compensated by gift vouchers at present, however as the online contracts emerge towards smart contracts, the breaches could potentially lead to court injunctions over blockchains. This research proposes Probability based Factor Model (PFM) that can be implemented over the blockchain to automatically identify breaches that can cause substantial damage and have high probability for recurrence. PFM can also issue court injunctions for the breaches. The underlying concept in PFM is built upon the notion of factor analysis and stochastic modeling from the discipline of Data Science. High performance computing (HPC) cluster at University of Luxembourg (HPC @ Uni.lu) and docker (a software container platform) were used to emulate contractual environment of three service providers: Redis, MongoDB, and Memcached Servers. The results showed that court injunction(s) was issued only for Redis and MongoDB Servers. Technically, this difference could be attributed to the fact that Memcached is simply used for caching and therefore, it is less prone to breach of contract. Whereas, Redis and MongoDB as databases and message brokers are performing more complex operations and are more likely to cause a breach. This research will benefit enterprises that view breach of contract as a limiting factor for implementation of smart contract in cyber physical system or internet of things. [less ▲]

Abstract: Recent studies have shown that the use of the forced answering (FA) option in online surveys results in reduced data quality. This response behavior has often been interpreted as psychological reactance reaction. However, no study researched the psychological mechanism behind the correlation of FA on dropout and data quality before. By using online survey-experiments with forced and non-forced answering instructions, our study offers statistical evidence for the often proposed reactance effect influencing response behavior. Relevance: Recent studies have shown that the use of the forced answering (FA) option in online surveys results in reduced data quality. They especially examined that forcing respondents to answer questions in order to proceed through the questionnaire leads to higher dropout rates and lower answer quality. However, no study researched the psychological mechanism behind the correlation of FA on dropout and data quality before. This response behavior has often been interpreted as psychological reactance reaction. So, the Psychological Reactance Theory (PRT) predicts that reactance appears when an individuals’ freedom is threatened and cannot be directly restored. Reactance describes the motivation to restore this loss of freedom. Respondents could experience FA as a loss of freedom, as (s)he is denied the choice to leave a question unanswered. According to PRT, possible reactions in this situation might be to quit survey participation, to fake answers or to show satisficing tendencies. Research content: This study explores the psychological mechanism that effects response behavior in FA condition (compared to non-FA- condition). Our major hypothesis is that forcing respondents to answer will cause reactance, which turns into increasing dropout rates, decreasing answer quality and a satisficing behavior. Methods and Data: We used online survey-experiments with forced and non-forced answering instructions. Reactance was measured with a four-item reactance scale. To determine answer quality, we used self-report for faking as well as the analysis of answers to open ended questions. Results: Zero-order effects showed that FA increased state reactance and questionnaire dropout as well as it reduced answer length in open-ended questions. Mediation analysis supported the hypothesis of reactance as an underlying psychological mechanism behind negative FA effects on data quality. Added Value: This is the first study which offers statistical evidence for the often proposed reactance effect influencing response behavior. This offers a base for a deeper psychological reflection of the use of the FA-option. [less ▲]
