Male students with immigrant backgrounds are disproportionally referred for special educational support outside regular classrooms or schools, which may reflect differential teachers´ expectations concerning the academic achievement of students based on socio-demographic characteristics. Although research has indicated differential teachers´ expectations for students based on immigrant background or special educational needs (SEN), less is known about a possible double vulnerability associated with combined stereotypes. Therefore, in the current study both SEN and immigrant background were systematically varied and teachers were asked to rate the students´ academic achievement. Results show that teachers´ expectations of students with SEN and immigrant background was lower than for students without immigrant background, especially in regards to language proficiency. These results may help to explain the overrepresentation of students with immigrant background in special educational programs. The educational and theoretical implications of these findings are discussed. [less ▲]

Uncertainty in timing properties (e.g., detection time of external events) is a common occurrence in embedded software systems since these systems interact with complex physical environments. Such time uncertainty leads to non-determinism. For example, time-triggered operations may either generate different valid outputs across different executions, or experience failures (e.g., results not being generated in the expected time window) that occur only occasionally over many executions. For these reasons, time uncertainty makes the generation of effective test oracles for timing requirements a challenging task. To address the above challenge, we propose STUIOS (Stochastic Testing with Unique Input Output Sequences), an approach for the automated generation of stochastic oracles that verify the capability of a software system to fulfill timing constraints in the presence of time uncertainty. Such stochastic oracles entail the statistical analysis of repeated test case executions based on test output probabilities predicted by means of statistical model checking. Results from two industrial case studies in the automotive domain demonstrate that this approach improves the fault detection effectiveness of tests suites derived from timed automata, compared to traditional approaches.

Synthetic opioids (SO) are a major risk for public health across the world. These drugs can be divided into 2 categories, pharmaceutical and non-pharmaceutical fentanyls. A new generation of SO has emerged on the drug market since 2010. North America is currently facing an opioid epidemic of morbi-mortality, caused by over-prescription of opioids, illegally diverted prescribed medicines, the increasing use of heroin, is and the emergence of SO. Furthermore, this opioid crisis is also seen in Europe. SO are new psychoactive substances characterized by different feature such as easy availability on the Internet, low price, purity, legality, and lack of detection in laboratory tests. They have not been approved or are not recommended for human use. Opioid misuse is associated with somatic and psychiatric complications. For many substances, limited pharmacological information is available, increasing the risk of harmful adverse events. Health actors and the general population need to be clearly informed of the potential risks and consequences of the diffusion and use of SO. [less ▲]

From the theory of compensatory Internet use, escapism through videogames may constitute a coping strategy that is sometimes helpful but, in some cases, maladaptive. Yet, evidence supporting this view has, to date, been gathered only through the use of explicit self-reported questionnaires, which are known to be biased. Accordingly, the aim of the current study was to test whether the escapism motive is related to a preference for the virtual environment. Method. A laboratory task that allowed the measurement of implicit attitudes, namely, the Affect Misattribution Procedure was created with stimuli from real world and videogames. The task was administered online with a series of questionnaire and completed by 273 online gamers from the community. Results. The results showed that participants had more positive attitudes toward pictures depicting virtual environments than toward those depicting real environments. Furthermore, those participants who frequently used videogames to escape real life and were highly engaged in video gaming had a more pronounced positive implicit attitude toward the virtual environment. Discussion. This study contributes to a better understanding of the psychological processes underlying escapism in videogames and calls for a refinement of the escapism construct, which can be related to both problematic (i.e., potential coping strategy) and nonproblematic patterns of videogame use. Among the limitations, it should be noted that the selection of stimuli related to videogames is restricted to one genre of game, and that the participants’ environment could not be controlled due to the online design.

This paper historicizes “rigour”, discipline” and “systematic” as inventions of a certain rational spirit of Enlightenment that was radicalized during the 19th century. These terms acquired temporary value in a transition during the 19th century when a culture of research was established within a modern episteme. Beginning in the 20th century, this development was perceived as problematic, triggering criticism from philosophy and the arts, and even within the sciences. “Discipline”, “rigour” and “systematic” have changed meanings over time, and recent contributions from Digital Humanities are promising for a renewed critical debate about rigour in research. Both digital humanities and quantitative research deal with big data sets aimed at providing a large-scale analysis. However, unlike most quantitative research, digital humanities explore uncertainties as their main focus. Attention to the human-machine collaboration has led to more expansive thinking in scientific research. Digital humanities go further by advancing a metaperspective that deals with the material hermeneutics of data accumulation itself. [less ▲]

The aim of the current study was to investigate if startle methodology is suitable to reflect urinary urgency. Eighteen healthy men were tested on two separate days, each including an ingestion of fluid until 80% of the subjective urge to micturate was reached. EMG responses to acoustic startle stimuli were assessed before and after micturition, as well as in the early and late cardiac cycle phases (230 vs. 530 ms after a cardiac R-wave). Sonographic assessment confirmed bladder-filling status. Emotional arousal, stress, urge and unpleasantness ratings, as well as mean blood pressure were higher before than after micturition. Startle eye blink responses were lower during the early than during the late cardiac cycle phase, but were not affected by bladder filling status. We conclude that startle methodology is suitable for the investigation of afferent signals from the cardiovascular system, but not to reflect urinary urgency. This result may be due to different neurophysiological mechanisms underlying afferent signals from the bladder compared to other visceral organs or interference with affective states or sympathetic activation associated with bladder filling. Notwithstanding, the present research protocol of fluid intake, sonographic assessment of the bladder, and subjective reports, can be applied to examine visceral-afferent signals from the bladder.

The widespread practice of binge-watching (i.e. watching multiple episodes of a TV series in one session) recently generated concerns about associated negative outcomes. Its psychological investigation, however, remains fragmentary. Based on the previous phenomenological investigation of TV series watching, we developed and validated two original assessment instruments, assessing TV series watching motives and binge-watching engagement and symptoms, respectively. Preliminary items were created for each questionnaire, and a focus group with TV series viewers was conducted and analyzed to generate the final instruments. The questionnaires were then administered via an online survey (N=6556), together with complementary measures of affect, problematic Internet use and substance use. Exploratory and confirmatory factor analyses, along with correlational analyses, were performed to examine both structural and external validity of the scales. The factorial analyses resulted in a 4-factor model (i.e. emotional enhancement, enrichment, coping-escapism and social) for the Watching TV Series Motives Questionnaire (WTSMQ), and in a 7-factor model (i.e. engagement, positive emotions, desire-savoring, pleasure preservation, binge-watching, dependency and loss of control) for the Binge-Watching Engagement and Symptoms Questionnaire (BWESQ). The results suggest good psychometric properties for both scales. The current study thus provides theoretically-driven and psychometrically sound instruments for further research on binge-watching behaviors [less ▲]

Complex problem solving (CPS) is a highly transversal competence needed in educational and vocational settings as well as everyday life. The assessment of CPS is often computer-based, and therefore provides data regarding not only the outcome but also the process of CPS. However, research addressing this issue is scarce. In this article we investigated planning activities in the process of complex problem solving. We operationalized planning through three behavioral measures indicating the duration of the longest planning interval, the delay of the longest planning interval and the variance of intervals between each two successive interactions. We found a significant negative average effect for our delay indicator, indicating that early planning in CPS is more beneficial. However, we also found effects depending on task and interaction effects for all three indicators, suggesting that the effects of different planning behaviors on CPS are highly intertwined. [less ▲]

The pure risk sharing mechanism implies that financial liberalization is growth enhancing for all countries as the world portfolio shifts from safe low-yield capital to riskier high-yield capital. This result is typically obtained under the assumption that the volatilities for risky assets prevailing under autarky are not altered after liberalization. We relax this assumption within a simple two-country model of intertemporal portfolio choices. By doing so, we put together the risk sharing effect and a well defined instability effect. We identify the conditions under which liberalization may cause a drop in growth. These conditions combine the typical threshold conditions outlined in the literature, which concern the deep characteristics of the economies, and size conditions on the instability effect induced by liberalization.

This paper aims at studying the impact of public persuasion, through information dissemination, on environmental and economic performance. A differential game in which opposite interest groups compete for bringing the majority’s environmental concern closer to their views is developed. The results show a strong asymmetry in the impact of public persuasion. It may bring the median voter economy closer to the social optimum in the long run, thereby reducing environmental and economic distorsions. But this only occurs when the environmental group exhibits a radical ideology and people are initially closer to the industrialists’ views. By contrast, economies where industrial groups are powerful and strongly opposed to environmental protection never benefit from the outcome of the game of persuasion. This may explain why the US have failed to take action on global warming up to now. [less ▲]

Where should Chinese internal migrant parents locate their school-aged children: migrate with them or leave them behind? And should they invest in private education of their children? We investigate whether migrant parents can afford to take their children to migrate and thus provide theoretical optimum that maximizes migrant parents’ utility which includes the children’s educational performance. Depending on the educational investment parents make and the relocation cost of children, we provide necessary and sufficient conditions under which migrant parents should take their children to migrate and conditions under which migrant parents should provide their children with private education.

This article compares Jewish responses to antisemitism in Paris and London in the late 1930s, when antisemitism was on the rise in both France and the United Kingdom. There were striking similarities in these responses, yet local contexts and circumstances dominate the historiographies of both cases. The main aim of this article, then, is not so much to offer new insights into the individual cases (both of which have been abundantly analyzed in historical research), but rather to fill a gap by examining the broader factors that account for these similarities. On the one hand, the article examines the nature of Jewish self-identification in the post-Emancipation era and its effects on the political cultures, practices, and identifications of the actors that were involved; on the other, it explores the way in which these practices were also shaped by migration and transnational aspects. Ultimately, this case study will argue for a comparative and transnational approach to Jewish political history in order to arrive at a better understanding of its diverse configurations and permutations.
