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.

Community low carbon transitions – studies of the ways in which community is used to pursue environmental aims and objectives – are closely linked to arrangements of energy production and use. Community is used as a way to pursue particular energy agendas. Yet, as is often pointed out, the trajectory of transitions imagined, the ambitiousness of the envisioned transformation, and especially the implied community invoked within this, all remain gloriously inconsistent. Within community transitions attention increasingly focuses on the tensions emerging or smoothed over as competing agendas are brought together through capacious words and concepts: for example between so-called top-down government deployed community, and so-called bottom-up emergent community action. This paper offers one way to explain and explore these tensions, where they come from and, thus, help in understanding ways in which they may be overcome. Using the case study of an attempt to target one ‘street community’s’ environmental footprint in Scotland, the paper argues for taking an explicitly geographical and spatial lens to analyse these processes. The paper uses three forms of space—perceived space, conceived space, and lived space—to outline how three distinct but overlapping communities were spatialised. The contention of the paper is that tensions in community transitions often result from different spatial imaginaries, informing one’s approach to, and ‘common sense’ understanding of, community. In reflecting on the spatial implications different forms of community produce (and are in turn produced by), the article argues for greater appreciation of the imbrication of space, community, and energy as mutually co-constitutive.

Care for elderly persons has many facets and is influenced by many factors of the care-dependent person, the care giver(s) and the micro-, and macro-social context. A co-operation of multiple disciplines is required to better understand phenomena of elder care and to act adequately in this field. This is even more urgent given the increasing population aging and the impending gaps between demand and supply of care. The present book provides a first substantive integration of knowledge from geropsychology, other gerosciences, and cultural psychologies to reach these goals —through a multi-disciplinary and international cast of authors. Macro-social context—including demographic, historical, political, normative, and other cultural factors—turned out to open and limit the available options for individual care giving and receipt and shapes how these issues are experienced by the participants in elder care. Elder care is shown to be far more complex than previously thought, because its consequences extend beyond single care givers to multigenerational caring families. Thinking, feeling and acting in relation to care dependency, caregiving and care receipt emerged as being influenced by multiple individual and social level factors. Future issues of elder care are seen as being shaped to a large extent by macro level factors such as population aging, social trends in job and family life, and development of assistive technologies. All this has far reaching implications for ensuring quality of care and the life quality on part of care recipients and care providers and for the coherence of social communities. [less ▲]

Neben Globalisierung und Digitalisierung haben Fragen der Meritokratie und (Aus-)Bildung einen festen Platz im öffentlichen, politischen und privaten Diskurs, denn wir leben in Europa zunehmend in Bildungsgesellschaften. Die Zeit, die wir in Bildungsorganisationen verbringen, wird immer länger, der absolvierte Fächerkanon wird immer breiter und die Bildungsabschlüsse, die wir erwerben, werden immer höher (vgl. Leemann et al. 2016). Zugleich steigen mit dem Übergang von der Industrie- zur modernen Dienstleistungsgesellschaft die Ansprüche an fachliche und soziale Kompetenzen auf dem Arbeitsmarkt (vgl. Mayer und Solga 2008). Mit dem Wandel der Wirtschaftsstrukturen hin zu wissensbasierten Tätigkeiten, der zunehmenden Digitalisierung der Arbeitswelt, den demographischen Veränderungen und dem in diesem Zusammenhang befürchteten Fachkräftemangel stehen europäische Gesellschaften vor der Aufgabe ihre Bildungssysteme zu reformieren. Auf europäischer, nationaler wie auch regionaler und lokaler Ebenen versuchen Bildungspolitiker den Zugang zu Hochschul- und Berufsbildung und lebenslanges Lernen für immer mehr Mitglieder jeder Kohorte zu ermöglichen. Alle müssen sich mehr denn je um Bildungszertifikate bemühen, weil diese für erfolgreiche Berufskarrieren unabdingbar geworden sind. Zugleich gibt es in diesem Wettbewerb klare Gewinner und Verlierer, denn diejenigen ohne Zugang zu (Aus-)Bildung, vor allem ehemalige Sonderschüler und Hauptschüler, werden zunehmend marginalisiert (vgl. Pfahl 2011; Protsch 2014; Solga 2005). Bildung und die durch sie erworbenen und ausgewiesenen Fähigkeiten gelten in unserer Gesellschaft als Innovationspotenzial, als zentrale Voraussetzungen für wirtschaftlichen Erfolg, gesellschaftlichen Wohlstand sowie soziale und politische Teilhabe. Statt der sozialen Platzierung entlang zugeschriebener Merkmale der Herkunft (wie Schicht, Geschlecht, Rasse, Ethnie) soll die erworbene Leistung, signalisiert in Schulnoten, Bildungsabschlüssen, Qualifikationen sowie Bildungskarrieren insgesamt, den legitimen Zugang zu Positionen, insbesondere höheren sozialen Positionen bestimmen. Insofern ist es nicht verwunderlich, dass in europäischen Gesellschaften individuelle Bildungsbeteiligung und Bildungserfolg wesentliche Bestimmungsgrößen der Verteilung gesellschaftlicher Chancen und Risiken darstellen.

Parkinson’s disease (PD) is a prime example of a complex and heterogeneous disorder, characterized by multifaceted and varied motor- and non-motor symptoms and different possible interplays of genetic and environmental risk factors. While investigations of individual PD-causing mutations and risk factors in isolation are providing important insights to improve our understanding of the molecular mechanisms behind PD, there is a growing consensus that a more complete understanding of these mechanisms will require an integrative modeling of multifactorial disease-associated perturbations in molecular networks. Identifying and interpreting the combinatorial effects of multiple PD-associated molecular changes may pave the way towards an earlier and reliable diagnosis and more effective therapeutic interventions. This review provides an overview of computational systems biology approaches developed in recent years to study multifactorial molecular alterations in complex disorders, with a focus on PD research applications. Strengths and weaknesses of different cellular pathway and network analyses, and multivariate machine learning techniques for investigating PD-related omics data are discussed, and strategies proposed to exploit the synergies of multiple biological knowledge and data sources. A final outlook provides an overview of specific challenges and possible next steps for translating systems biology findings in PD to new omics-based diagnostic tools and targeted, drug-based therapeutic approaches.

Background: Although itch and pain are distinct experiences, both are unpleasant, and may demand attention and interfere with daily activities. Research investigating the role of attention in tonic itch and pain stimuli, particularly whether attention is drawn to the stimulus location, is scarce. Methods: In the somatosensory attention task, fifty-three healthy participants were exposed to 35-seconds electrical itch or pain stimuli on either the left or right wrist. Participants responded as quickly as possible to visual targets appearing at the stimulated location (ipsilateral trials) or at the arm without stimulation (contralateral trials). During control blocks, participants performed the visual task without stimulation. Attention allocation at the itch and pain location is inferred when responses are faster ipsilaterally than contralaterally. Results: Results did not indicate that attention was directed towards or away from the itch and pain location. Notwithstanding, participants were slower during itch and pain than during control blocks. Conclusions: In contrast with our hypotheses, no indications were found for spatial attention allocation towards the somatosensory stimuli. This may relate to dynamic shifts in attention over the time course of the tonic sensations. Our secondary finding that itch and pain interfere with task performance is in line with attention theories of bodily perception. [less ▲]
