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.

Inclusive education has become a global norm, supported by the recognition of human rights, and now affects education policymaking and system development worldwide. While important contributions in sociological research on education, disability, and inequality exist, those in life course perspective and international comparative perspectives are rarer. Studies of educational opportunities of children and youth with disabilities and disadvantages over the past several decades underscore the lack of systematic approaches to facilitate educational and social inclusion. Within the educational research field, sociological approaches to disability, to special educational needs, and to inclusive education emphasize such dimensions as exclusion/inclusion, segregation/integration, learning opportunities, in/equality, institutionalization, stigma, risk, and certification or credentials. To recognize and understand the causes and consequences of disability-related inequality requires in-depth dialogue and benefits from results of studies on different levels and within diverse cultural contexts. This article provides insights into disability and inequality in educational opportunities across Europe and an overview of research topics, results, and gaps. The sociology of education would increase its contribution were it to be more inclusive in analyzing the processes that affect educational opportunities and life chances of those who experience disablement in schooling.

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 ▲]

Dysfunctional use of cybersex has often been conceptualized as a 'behavioral addiction' sharing common traits with substance addiction. We describe the case of a treatment-seeking man, who displayed addictive use of pornography. The case is presented from two perspectives: (1) a symptom-based approach inspired by the addiction model of excessive sexual behaviors and (2) a process-based approach aimed to identify the psychological processes and risk factors that may foster the development of addiction-like symptoms. This article shows how case conceptualization according to a process-based approach is likely to result in psychological intervention that targets the specific processes and risk factors involved in addictive cybersex use.

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.

We explore the relationship between the characteristics of social capital, the speed of access to medical technologies and the role of gender in a private practice context. Our findings from a sample of 98 German private practitioners show that: (a) being a woman has an overall negative impact on the speed of access to medical technologies; (b) private practitioners with strong social network ties obtain quicker access to medical technologies than do those with weak ties; (c) men relying on their weak ties perform better than women who do so. In contrast, we observe that women relying on strong ties outperform their male counterparts in terms of speed of access to medical technologies. [less ▲]

We present an approach for performing the tallying work in the coercion-resistant JCJ voting protocol, introduced by Juels, Catalano, and Jakobsson, in linear time using fully homomorphic encryption (FHE). The suggested enhancement also paves the path towards making JCJ quantum-resistant, while leaving the underlying structure of JCJ intact. The exhaustive, comparison-based approach of JCJ using plaintext equivalence tests leads to a quadratic blow-up in the number of votes, which makes the tallying process rather impractical in realistic settings with a large number of voters. We show how the removal of invalid votes can be done in linear time via a solution based on recent advances in various FHE primitives such as hashing, zero-knowledge proofs of correct decryption, verifiable shuffles and threshold FHE. We conclude by touching upon some of the advantages and challenges of such an approach, followed by a discussion of further security and post-quantum considerations. [less ▲]

Objective: Chronic pain is central to Juvenile Idiopathic Arthritis (JIA) and is predictive of impaired functioning. Whereas most work has focused on identifying psychosocial risk factors for maladaptive outcomes, we explored the idea that child and parental psychological flexibility (PF) represent resilience factors for adaptive functioning of the child. We also explored differences between general versus pain-specific PF in contributing to child outcomes. Methods: Children with JIA (8-18 years) and (one of) their parents were recruited at the department of pediatric rheumatology at the Ghent University Hospital in Belgium. They completed questionnaires assessing child and parent general and pain-specific PF and child psychosocial and emotional functioning, and disability. Results: The final sample consisted of fifty-nine children and forty-eight parents. Multiple regression analyses revealed that child PF contributed to better psychosocial functioning and less negative affect. Child pain acceptance contributed to better psychosocial functioning, lower levels of disability and lower negative affect, and also buffered against the negative influence of pain intensity on disability. Bootstrap mediation analyses demonstrated that parental (general) PF indirectly contributed to child psychosocial functioning and affect via the child’s (general) PF. Parent pain-specific PF was indirectly linked to child psychosocial functioning, disability, and negative affect via child pain acceptance. Conclusion: Our findings indicate that child and parental PF are resilience factors and show that pain acceptance buffers against the negative impact of pain intensity. Implications for psychosocial interventions that target (pain-specific) PF in children as well as in parents are discussed. [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 ▲]

This paper analyses the impact of credit information sharing on financial stability, drawing special attention to its interactions with credit booms. A probit estimation of financial vulnerability episodes—identified by jumps in the ratio of non-performing loans to total loans—is run for a sample of 159 countries divided into two sub-samples according to their level of development: 80 advanced or emerging economies and 79 less developed countries. The results show that: i) credit information sharing reduces financial fragility for both groups of countries; ii) for less developed countries, the main effect is the direct effect (reduction of NPL ratio once credit boom is controlled), suggesting a portfolio quality effect; iii) credit information sharing also mitigates the detrimental impact of a credit boom on financial fragility but this result holds only for advanced and emerging countries and for household credit booms; and iv) the depth of information sharing has a negative impact on the likelihood of credit booms (but not the coverage of IS).
