Gambling disorder is a well-established behavioural addiction, which was classified with substance-related disorders in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders. Although craving was introduced as a new diagnostic criterion for substance-related disorders, it was not included for gambling disorder. This study aimed to explore the experience of gambling craving and to evaluate whether the elaborated intrusion theory of desire (EIT), a cognitive model of craving, fits gambling craving. A mixed methods study was conducted among 31 non-clinical gamblers. The qualitative part consisted of open-ended questions targeting the components of the EIT. The quantitative part consisted of a questionnaire designed to assess triggers and descriptions of gambling craving. Qualitative analysis revealed six distinct conceptual categories related to gambling craving: positive and negative affect, external cues, mental imageries, thoughts and physiological sensations. The quantitative analysis highlighted the most relevant triggers (e.g. spontaneous thoughts) and experiential characteristics (e.g. visual imagery) of gambling craving. The present study allowed the authors to support the relevance of the EIT as it applies to gambling craving by disentangling its core features. Findings from this study suggest that the use of interventions derived from the EIT may be relevant for problem gambling treatment. [less ▲]

This paper aims to design joint precoding and onboard beamforming of a multiple gateway multibeam satellite system, either in a hybrid space-ground mode, or in a totally on-board one. In such an architecture, with employing high throughput full frequency reuse pattern over both user and feeder links, each gateway serves a cluster of adjacent beams such that the adjacent clusters are served through a set of gateways that are located at different geographical areas. However, such a system brings in two challenges to overcome. First, the interference in both user and feeder links is the bottleneck of the whole system and applying interference mitigation techniques becomes necessary. Second, as the data demand increases, the ground and space segments should employ extensive bandwidth resources in the feeder link accordingly. This entails embedding an extra number of gateways aiming to support a fair balance between the increasing demand and the corresponding required feeder link resources. To solve these problems, this study investigates the impact of employing a joint multiple gateway architecture and on-board beamforming scheme. It is shown that by properly designing the on-board beamforming scheme, the number of gateways can be kept affordable even if the data demand increases. Moreover, Zero Forcing (ZF) precoding techniques are considered to cope with the interference in both user and feeder links which embed in the following premises: (i) each gateway constructs a part of block ZF precoding matrix, (ii) the satellite and gateways perform the precoding scheme, and (iii) a joint design of ZF precoding and on-board beamforming at the payload of the satellite so that no signal processing scheme is conceived at the gateways. The provided simulation results depict the performance gain obtained by our proposed schemes. [less ▲]

Attention plays a pivotal role in the experience of pain and its impact upon daily activities. Accordingly, research on the interplay between attention and pain has a long scientific history. Within this chapter, we discuss the theoretical frameworks that aim to explain the relationship between attention and pain. We argue for a motivational perspective on pain that highlights the critical role of cognitive, affective and contextual factors in explaining the interplay between attention and pain. To substantiate this argument, we provide an overview of available research addressing the bottom-up capture of attention by pain and the top-down modulation (both inhibition and facilitation) of attention for pain. We conclude this chapter with guidelines and suggestions for future research and discuss clinical implications of adopting a motivational perspective on pain. [less ▲]

Background and aims: Binge-watching (i.e., seeing multiple episodes of the same TV series in a row) now constitutes a widespread phenomenon. However, little is known about the psychological factors underlying this behavior, as reflected by the paucity of available studies, most merely focusing on its potential harmfulness by applying the classic criteria used for other addictive disorders without exploring the uniqueness of binge-watching. The present study thus aimed to take the opposite approach as a first step toward a genuine understanding of binge-watching behaviors through a qualitative analysis of the phenomenological characteristics of TV series watching. Methods: A focus group of regular TV series viewers (N=7) was established to explore a wide range of aspects related to TV series watching (e.g., motives, viewing practices, related behaviors). Results: A content analysis identified bingewatching features across three dimensions: TV series watching motivations, TV series watching engagement, and structural characteristics of TV shows. Most participants acknowledged that TV series watching can become addictive, but they all agreed having trouble recognizing themselves as truly being an “addict.” Although obvious connections could be established with substance addiction criteria and symptoms, such parallelism appeared to be insufficient, as several distinctive facets emerged (e.g., positive view, transient overinvolvement, context dependency, low everyday life impact). Discussion and conclusions: Research should go beyond the classic biomedical and psychological models of addictive behaviors to account for binge-watching in order to explore its specificities and generate first steps toward an adequate theoretical rationale for these emerging problematic behaviors.

Accuracy in assessing academic achievement and potential is a core component of teachers’ diagnostic competence. Large-scale studies in the Luxembourgish and German educational systems show that teachers’ secondary school track decisions are biased by a student’s social background. Therefore, biased assessment of students may contribute to the social inequalities observed in secondary schools in both countries. Within a social cognitive framework of dual-process theories, bias is explained by heuristic information processing, which, in contrast to information-integrating processing, relies on stereotype-based expectations to form judgments about students. A series of experimental studies investigated the information processing strategies of teachers, identifying a low accountability of the decision setting and a high consistency of student information as key moderators that promote stereotype-based information processing strategies in teachers’ school track decisions. Similar effects were shown for novice teachers at the beginning of their professional career. Further research evaluated intervention modules based on increased accountability, feedback, and increased knowledge about judgment formation processes. Results demonstrated that all evaluated intervention modules led to higher judgment accuracy and more information-integrating processing. Reviewing current models of teachers’ diagnostic competence, the findings on teachers’ information processing emphasized the need to include situational and process-oriented components into models of diagnostic competence. Beside a cognitive component – the ability to form accurate and unbiased judgments – diagnostic competence includes an adaptive choice of information processing strategies, depending on the accountability and information consistency of the judgment setting. Results on intervention modules gave insights how to increase diagnostic competence in teacher education programs. [less ▲]

We compute the equivariant K-homology of the classifying space for proper actions, for cocompact 3-dimensional hyperbolic reflection groups. This coincides with the topological K-theory of the reduced C*-algebra associated to the group, via the Baum-Connes conjecture. We show that, for any such reflection group, the associated K-theory groups are torsion-free. This means that we can complete previous computations with rational coefficients to get results with integral coefficients. On the way, we establish an efficient criterion for checking torsion-freeness of K-theory groups, which can be applied far beyond the scope of the present paper. [less ▲]

Attentional strategies, such as distraction and sensory monitoring, are often offered to reduce pain and pain-related distress. However, evidence for their efficacy in chronic pain patients is equivocal. We report a meta-analysis on the efficacy of distraction and sensory monitoring in chronic pain patients, and explore possible methodological and theoretical moderators. The scientific literature was searched for relevant articles, which were coded for methodological quality and several theoretical and methodological moderator variables. Only 10 articles fulfilled the search criteria. Eight studies allowed us to compare distraction with a control condition, two studies to compare sensory monitoring with a control condition, and four studies to compare the effect of distraction with the effect of sensory monitoring. Overall, results indicate that distraction did not differ from control in altering pain experience (k=8; Hedges’ g=0.10, ns) and distress (k=2; Hedges’ g=0.549). Sensory monitoring did also not alter pain experience (k=2; Hedges’ g=-.21, ns) and distress (k=1; Hedges’ g=-0.191, ns). We found no evidence to support the superiority of distraction or sensory monitoring in altering pain compared to control conditions. We offer guidance for future theory-driven research to investigate distraction and sensory monitoring in this largely unexplored field, albeit one replete with methodological difficulties. [less ▲]

A novel multiscale approach for three-phase flows is presented. The goal of the proposed method is to solve arbitrary three-phase flow configurations in a computationally efficient way, and in particular taking into account the effects of different length scales while sharply reducing the computational burden. This is particularly important in chemical, environmental, and process engineering, where large-scale quantities are normally of interest, but small-scale dynamics cannot be neglected. The method is based on the definition of two different length scales: the bulk scale, and the fluid fine scale. A dual-grid approach is adopted in order to resolve the bulk scale with information from the fluid fine scale. It is shown that the described method succeeds in delivering more accuracy than a standard approach based on the volume averaging technique, still, it remains suitable for the solution of real interest problems. The method is shown to successfully satisfy experimental results presented in the literature. Examples of three-phase flows simulations are provided to show how the proposed numerical approach can describe the physics of particle-laden, free surface flows with competitive computational cost. It is shown how the proposed method can naturally extend the DEM-VOF method to the presence of complex interface dynamics. [less ▲]

This study on metacognition of time examined the confidence judgment in the temporal generalization task when the difficulty of temporal discrimination increased, in three different standard duration conditions. The results showed that participants’ confidence judgments were accurate for all comparison durations similar to the standard duration and varied only for the comparison durations shorter or longer than the standard duration. The confidence judgment did not change with the standard duration condition; except for an overconfidence level for the comparison durations longer than the standard in the shortest standard duration condition. Moreover, the results showed that the overconfidence level increases with the increase in temporal discrimination difficulty, although an underconfidence level was found but only for the shortest comparison durations. The implication in terms of decision processes for the generalization temporal task and in terms of metacognitive processes are discussed. [less ▲]

Aggressive drivers can make driving dangerous. Over 50% of traffic fatalities are caused by aggressive driving. Aggressive motorists make driving very dangerous. This research tests whether narcissists are more aggressive drivers than other individuals. Narcissists think they are special people who deserve special treatment. When they don’t get the special treatment they think they deserve, narcissists often lash out at others in an aggressive manner. Narcissists might think they “own the road” and can drive anyway they want, and that other drivers should get out of their way. In the article, we conduct three studies to test the link between narcissism and aggressive driving. In Studies 1 (N=139) and 2 (N=100), Luxembourgish motorists completed a measure of narcissism and a self-report measure of aggressive driving. In Study 3 (N=60), American university students completed a measure of narcissism and then completed a driving simulation scenario that contained a number of frustrating elements. Several measures of aggressive driving and road rage were obtained. In all three studies, narcissism was positively related to aggressive driving. A meta-analysis found an average correlation of r=.35 across the three studies. This research replicates previous research linking narcissism to aggression, and extends it to a driving context.
