Knowledge co-production is a solution-oriented approach to analysing real-life problems such as making the right decision in a given scenario. The most popular examples come from evidence-based policymaking contexts. Political decisions made in this way rely on specialist expertise co-produced in organisations that can be characterised as Hybrid Fora. However, despite the rise in popularity of Hybrid Fora and evidence-based policymaking processes, there are only a few studies that analyse the influencing factors of knowledge co-production in these contexts. The case study presented here addresses this new area of research through a documentary analysis and 11 expert interviews, both analysed via qualitative content analysis. First, the study reconstructs how knowledge is produced within an Expert Group of the European Commission. Second, it reflects how the produced knowledge is de facto included as “evidence” into the decision-making processes of the relevant policy area. The results of this study show that in this expert group, pragmatic and extra-scientific criteria such as specific stakes and interests as well as the group hierarchy controlled the process of knowledge co-production. Moreover, it also seems that knowledge produced by the interaction of experts within the examined Expert Group has a more symbolic, policy-orientated function, rather than being specifically used as decision-making evidence.

The aim of the present study was to assess the usefulness of QTrobot, a socially assistive robot, in interventions with children with autism spectrum disorder (ASD) by assessing children's attention, imitation, and presence of repetitive and stereotyped behaviors. Fifteen children diagnosed with ASD, aged from 4 to 14 years participated in two short interactions, one with a person and one with the robot. Statistical analyses revealed that children directed more attention towards the robot than towards the person, imitated the robot as much as the person, and engaged in fewer repetitive or stereotyped behaviors with the robot than with the person. These results support previous research demonstrating the usefulness of robots in short interactions with children with ASD and provide new evidence to the usefulness of robots in reducing repetitive and stereotyped behaviors in children with ASD, which can affect children's learning.

In abstract argumentation theory, multiple argumentation semantics have been proposed that allow to select sets of jointly acceptable arguments from a given set of arguments based on the attack relation between arguments. The existence of multiple argumentation semantics raises the question which of these semantics predicts best how humans evaluate arguments, possibly depending on the thematic con- text of the arguments. In this study we report on an empirical cognitive study in which we tested how humans evaluate sets of arguments de- pending on the abstract structure of the attack relation between them. Two pilot studies were performed to validate the intended link between argumentation frameworks and sets of natural language arguments. The main experiment involved a group deliberation phase and made use of three different thematic contexts of the argument sets involved. The data strongly suggest that independently of the thematic contexts that we have considered, strong acceptance and strong rejection according to the CF2 and preferred semantics are a better predictor for human argument acceptance than the grounded semantics (which is identical to strong acceptance/rejection with respect to complete semantics). Furthermore, the data suggest that CF2 semantics predicts human argument acceptance better than preferred semantics, but the data for this comparison is limited to a single thematic context.

Workplace mobbing has various negative consequences for targeted individuals and are costly to organizations. At present it is debated whether gender, age, or occupation are potential risk factors. However, empirical data remain inconclusive as measures of workplace mobbing so far lack of measurement invariance (MI) testing – a prerequisite for meaningful manifest between-group comparisons. To close this research gap, the present study sought to further elucidate MI of the recently developed brief Luxembourg Workplace Mobbing Scale (LWMS; Steffgen, Sischka, Schmidt, Kohl, & Happ, 2016) across gender, age, and occupational groups and to test whether these factors represent important risk factors of workplace mobbing. Furthermore, we sought to expand data on criterion validity of the LWMS with different self-report criterion measures such as psychological health (e.g., work-related burnout, suicidal thoughts), physiological health problems, organizational behavior (i.e., subjective work performance, turnover intention, and absenteeism), and with a self-labeling mobbing index. Data were collected via computer-assisted telephone interviews (CATI) in a representative sample of 1,480 employees working in Luxembourg (aged from 16 to 66; 45.7% female). Confirmatory factor analyses revealed scalar MI across gender and occupation as well as partial scalar invariance across age groups. None of these factors impacted on the level of workplace mobbing. Correlation and receiver operating characteristic (ROC) analyses strongly support the criterion validity of the LWMS. Due to its briefness while at the same time being robust against language, age, gender, and occupational group factors and exhibiting meaningful criterion validity, the LWMS is particularly attractive for large-scale surveys as well as for single-case assessment and, thus, general percentile norms are reported in the Electronic Supplementary Materials.

In the present paper, a model-based fault/attack tolerant scheme is proposed to cope with cyber-threats on Cyber-Physicals Systems. A common scheme based on observers is designed and a state feedback control based on an aperiodic event-triggered framework is given with control synthesis and condition on the switching time. Classical fault tolerant control with Bi-linear Matrix Inequality () approaches are used to achieve novel and better security strategy based on an event-triggered control implementation. The purpose of using the event-based implementation would be to reduce (limit) the total number of transmissions to only instances when the networked control system (NCS) needs attention. Simulation results on a real-time laboratory three tank system are given to show the attack-tolerant control ability despite data deception attacks on both actuators and sensors. A detection/isolation scheme based on residual observers bank is also proposed. [less ▲]

This article aims to contribute to the reconstruction of Luxembourg’s war experience and to analyse Weber’s literary and theoretical renditions of these events. It will investigate Weber’s experience of non-experience and highlight the ways in which he sought to describe and overcome the sense of ineffectuality and uselessness that came with being ‘put on hold’ by the war as a nation and as a human being. Weber’s reflections mix physical, mental, and intellectual pain, creating a sense of absurdist, non-productive suffering, which he, with wavering conviction, seeks to counteract by drawing on the physicality of the personal and collective body.

Since more than 15 years, researchers have been expressing their interest in evaluating the Approximate Number System (ANS) and its potential influence on cognitive skills involving number processing, such as arithmetic. Although many studies reported significant and predictive relations between ANS and arithmetic abilities, there has recently been an increasing amount of published data that failed to replicate such relationship. Inconsistencies lead many researchers to question the validity of the assessment of the ANS itself. In the current meta-analysis of over 68 experimental studies published between 2004 and 2017, we show that the mean value of the Weber fraction (w), the minimal amount of change in magnitude to detect a difference, is very heterogeneous across the literature. Within young adults, w might range from <10 to more than 60, which is critical for its validity for research and diagnostic purposes. We illustrate here the concern that different methods controlling for non-numerical dimensions lead to substantially variable performance. Nevertheless, studies that referred to the exact same method (e.g., Panamath) showed high consistency among them, which is reassuring. We are thus encouraging researchers only to compare what is comparable and to avoid considering the Weber fraction as an abstract parameter independent from the context. Eventually, we observed that all reported correlation coefficients between the value of w and general accuracy were very high. Such result calls into question the relevance of computing and reporting at all the Weber fraction. We are thus in disfavor of the systematic use of the Weber fraction, to discourage any temptation to compare given data to some values of w reported from different tasks and generation algorithms.
