Equalization taxes have a number of potential disadvantages and shortcomings, including their negative impact on growth, innovation and productivity, non-neutrality, double taxation, and problems in compliance and administration. However, some also view them as a politically feasible way to address perceived ‘unfairness’ in the territorial allocation of taxing rights in a digitalized economy. In any event, however, there are also certain technical features any such tax should comply with, including, e.g. compliance with international obligations (e.g. EU and tax treaty law), administrative simplicity, and a scope that is not overreaching. This contribution will address the general background of ‘equalization taxes’, the fundamental objections raised against it, and the relevant design features, both on a general level and specifically with regard to the proposal for an EU ‘Digital Services Tax’.

The Ten-Item Internet Gaming Disorder Test (IGDT-10) is a short screening instrument developed to assess Internet gaming disorder (IGD) as proposed in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM–5), adopting a concise, clear, and consistent item-wording. According to initial studies conducted in 2014, the instrument showed promising psychometric characteristics. The present study tested the psychometric properties, including language and gender invariance, in a large international sample of online gamers. In this study, data were collected from 7,193 participants comprising Hungarian (n = 3,924), Iranian (n = 791), English-speaking (n = 754), French-speaking (n = 421), Norwegian (n = 195), Czech (n = 496), and Peruvian (n = 612) online gamers via gaming-related websites and gaming-related social-networking-site groups. A unidimensional factor structure provided a good fit to the data in all language-based samples. In addition, results indicated both language and gender invariance on the level of scalar invariance. Criterion and construct validity of the IGDT-10 was supported by its strong association with the Problematic Online Gaming Questionnaire and moderate association with weekly gaming time, psychopathological symptoms, and impulsivity. The proportions of each sample that met the cut-off score on the IGDT-10 varied between 1.61% and 4.48% in the individual samples, except for the Peruvian sample (13.44%). The IGDT-10 shows robust psychometric properties and appears suitable for conducting cross-cultural and gender comparisons across seven languages. [less ▲]

This article discusses the transnational heroic cult that developed in Yiddish communist circles around the figure of Naftali Botwin, a young Polish-Jewish communist who was executed by Polish authorities in the city of Lwów, following a trial in which he was convicted for assassinating a police infiltrator in the ranks of the Polish Communist Party (KPP). The discussion highlights how Botwin’s legacy was appropriated in multiple, and sometimes contrasting, ways in the decades following his death, especially within the context of the creation of the Botwin Company in the International Brigades during the Spanish Civil War. In doing so it will also highlight the transnational nature of this cult, as his memory lived on through poems, plays and publications that circulated through the worldwide networks and communicative spaces of Jewish (leftist) émigrés.

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.

Little effort has been made to systematically test the psychometric properties of the Gambling Craving Scale (GACS; Young & Wohl, 2009). The GACS is adapted from the Questionnaire on Smoking Urges (Tiffany & Drobes, 1991) and thus measures gambling-related urge. Crucially, the validation of scales assessing gambling urge is complex, as this construct is better conceptualized as a state (a transient and context-determined phenomenon). In the present study, we tested the psychometric properties of the French version of the GACS with 2 independent samples of community gamblers following an induction procedure delivered through an audio-guided imagery sequence aimed at promoting gambling urge. This procedure was specifically used to ensure the assessment of gambling urge as a state variable. Participants also completed measures of gambling severity, gambling cognitions and motives, impulsivity, and affect. Confirmatory factor analysis (CFA) showed that the original 3-factor solution (anticipation, desire, relief) did not fit the data well. Additional exploratory factor analysis (EFA) suggested instead a 2-factor solution: intention and desire to gamble dimension and a relief dimension. The factorial structure resulting from the EFA was tested with CFA in a second independent sample, resulting in an acceptable fit. The 2 dimensions presented good internal reliability and correlated differentially with the other study’s variables. The current study showed that, similar to what has been reported for substance-related urges, gambling urges are adequately probed with a bidimensional model. The findings suggest that the French GACS has good psychometric properties, legitimizing its use in research and clinical practice. [less ▲]

In today’s globalized society, linguistic and cultural worlds collide bringing people, cultures, and languages together in diverse ways that can influence a person’s identity and sense of self. Due to the porous boundaries of people’s identities, increased globalization can lead to identity confusion, which can influence how open individuals are to integration (Hermans and Hermans-Konopka 2010). This confusion increases as countries across the world experience what Vertovec (2006) describes as super-diversity, a “world in one city” (Benedictus and Godwin 2005, p. 2). Super-diversity can be described as a dynamic interplay of variables among increasing numbers of new, small and scattered, multiple-origin, transnationally connected, socio-economically differentiated, and legally stratified number of immigrants throughout the world (Vertovec 2007). While some researchers have claimed that globalization can result in a loss of cultural diversity (Tomlinson 2003), the integration of plurilingual and pluricultural people in diverse contexts can also result in greater awareness of diversity. To understand the impact of globalization on an individual’s identity and sense of self, research can be a powerful tool. In particular, research that critically focuses on examining oneself can reveal new knowledge of the self that may inform one’s research endeavors. In this chapter, we share the process of collaborative autoethnography (co-autoethnography), that we used to individually and collaboratively examine and reflect upon our experiences at the start of our doctoral research paths. We used this critical methodology to help us make sense of our individual and collective experiences in two different multilingual/multicultural research settings – South Korea and Luxembourg. Specifically, we attempt to tease apart the relationship that exists between language, culture, and self. In addition, building from a discussion of the benefits and challenges of implementing this method, we share what we learned from this narrative process about ourselves, and about how we engaged and continued to engage in science education research. We share our co-autoethnographic process that helped us push the boundaries of our research, and that gave each of us a deeper understanding of our own positionality within our research contexts. We do so with the hopes of encouraging other researchers to undergo such processes in order to further investigate their own self and the position of their selves in their research. [less ▲]

Neurocognitive models of attentional bias for threat posit that attentional bias may result from a decreased activation of the left prefrontal cortex, and especially of its dorsolateral part (dlPFC), resulting in an impaired attention control. Consequently, a transient increase of neural activity within the left dlPFC via non-invasive brain stimulation reduces attentional bias among both anxious and nonanxious participants. Yet, it is still unclear whether the impact of dlPFC activation on attentional bias is mediated by improvement in attention control. In this experiment, we sought to test this hypothesis in an unselected sample (n = 20). Accordingly, we adopted a double-blind within-subject protocol in which we delivered a single-session of anodal versus sham transcranial Direct Current Stimulation (tDCS) over the left dlPFC during the completion of a task assessing attention control. We also assessed its subsequent impact on attentional bias. Neither attention control nor attentional bias did significantly improve following anodal tDCS. Although our results did not support our main hypothesis, we believe the present null results to be particularly useful for future meta-research in the field. We also formulated a series of methodological recommendations for future research aiming at testing the tDCS-induced modification of attentional bias. [less ▲]

Background: Binge drinking, characterized by alternations between intense alcohol intakes and abstinence periods, is the most frequent alcohol consumption pattern among adolescents and has been repeatedly associated with cognitive and cerebral impairments. Objectives: In view of these harmful consequences, it appears crucial to disentangle the psychological factors involved in the emergence of binge drinking in adolescence, and centrally the role played by drinking motives, which have been strongly related to binge drinking habits. Methods: Using a longitudinal design, the present study explored the role of drinking motives (i.e. social order, conformity, enhancement, coping) in the emergence of binge drinking among young adolescents from the community. One hundred and forty-four young adolescents (81 girls) took part in a research assessing alcohol consumption and drinking motives at two assessment times (T1 and T2), with a one-year interval. After data checking, 101 adolescents (57 girls) aged from 12 to 15 years old were included in the study. Results: Correlations showed strong relationships between drinking motives and binge drinking. Additional regression analyses were then computed to determine how drinking motives assessed at T1 predicted binge drinking at T2, while controlling for global alcohol use. Results showed that the statistical model explained 60% of the binge drinking variance. In particular, the enhancement motivation, which is related to the search for the enjoyable sensations felt when drinking alcohol, constituted the unique predictor of future binge drinking. Conversely, in contrast with previous studies, social motives did not predict binge drinking in young adolescents. Conclusion: These findings highlight the central role of enhancement motivation (e.g., focusing on the positive expectancies towards alcohol) in youths’ alcohol consumption and call for the development of preventive interventions. It also suggests that the previously reported relationship between social motives and college drinking does not seem to play a key role in the early steps of binge drinking habits. [less ▲]

Background: Executive deficits have been largely reported in young binge drinkers during the last decade, but uncertainty remains regarding the specificity of these deficits and their variation across executive subcomponents. The current study aimed at offering a theoretically-grounded and specific exploration of the differential deficits observed across executive functions in binge drinkers. Method: A total of forty university students (20 binge drinkers; 10 women, and 20 matched controls; 12 women) performed three validated neuropsychological tasks, each exploring a specific executive function, namely shifting, updating, and inhibition (specifically Resistance to Distractor Interference). Tasks were presented to participants in pseudo-randomized order. Repeated measure analyses of variance were performed for each task to compare groups’ performance. Results: A dissociation was observed across executive tasks regarding group differences: compared to controls, binge drinkers demonstrated preserved performance for shifting and updating abilities, but impaired inhibition. These results support the central role of inhibitory control in excessive alcohol consumption. In contrast with severe alcohol-use disorders, binge drinking does not appear related to a general executive deficit. Conclusions: In view of the pivotal role played by inhibition impairments in the emergence of severe alcohol-use disorders, the present data claim for developing individualized evaluation and rehabilitation programs focusing on this executive subcomponent to improve control abilities at early stages of alcohol-related disorders.
