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 ▲]

While most societies are structured around diverse flows of people and complex linguistic repertoires, (language) education schemes are still dominated by monolingual instructional practices. This paper aims to contribute to current discussions on the affordances of multilingual pedagogies in contexts of forced migration. It draws on a range of linguistic ethnographic data (Copland & Creese, 2015) that was collected over the period of 2016-2017 in diverse settings of language learning and socialization. Our research sites in Luxembourg included language courses in French, English and German, mathematics courses, application and web development training, and diverse leisure activities. Having followed the learning trajectory of five asylum applicants, we explored how they built on their old and newly-acquired language resources. Our findings confirm that in order to make their voices heard, the learners often drew upon elements from multiple languages, including those local languages they had no extensive competence in. This multilingual orientation enabled them to see the local languages as new functional resources in their growing repertoires (Kalocsányiová, 2017). This is of special relevance in contexts of forced migration, where learners need to become users of the languages they are learning from the first day onward. [less ▲]

This chapter draws from the experience of the collective French Web90 project to show the approaches, tools, and methodologies required to sketch a broad historical picture of the French Web during the 1990s. It also describes the limits and challenges we met during its realisation. Uncertainties about the perimeter of the French Web and its archives, data overload, progressive learning of a particular digital literacy, specific features of born-digital heritage (Newsgroups and Web archives), and using the tools for its exploration and analysis are at the heart of this study, which has progressively refined and adapted its ambitions and methodologies, notably by using methods and tools from the Digital Humanities.

Sexual narcissism (SN) has recently been proposed to be a specific risk factor for the perpetration of sexual coercion based on both self-reports of previous behavior and self-estimated likelihood of engaging in acts of sexual violence. To explore one of the potential underlying mechanisms of SN, we tested whether for highly sexually narcissistic males (measured with the German language version of the Sexual Narcissism Scale) the subtle priming of sexual concepts would evoke aggressive behavior in a standard measure of aggressive behavior, the Taylor Aggression Paradigm. Results showed that only for sexually narcissistic men did a subtle priming with mildly erotic words lead to an increase in shock volumes administered to the alleged competitor on this task. For women, it was postulated that physical force would not be represented as a functional behavioral script for sexually narcissistic females and, in line with this hypothesis, no effects were found for women. The results were discussed with regard to the underlying processes of SN and the importance of an individual difference perspective in sex-aggression links. [less ▲]

We present a benchmark study for the adsorption of a large pi-conjugated organic molecule on different noble metal surfaces, which is based on x-ray standing wave (XSW) measurements and density functional theory calculations with van der Waals (vdW) interactions. The bonding distances of diindenoperylene on Cu(111), Ag(111), and Au(111) surfaces (2.51, 3.01, and 3.10 angstrom, respectively) determined with the normal-incidence XSW technique are compared with calculations. Excellent agreement with the experimental data, i.e., deviations less than 0.1 angstrom, is achieved using the Perdew-Burke-Ernzerhof (PBE) functional with vdW interactions that include the collective response of substrate electrons (the PBE + vdW(surf) method). It is noteworthy that the calculations show that the vdW contribution to the adsorption energy increases in the order Au(111) < Ag(111) < Cu(111). [less ▲]

Familial Hypercholesterolemia (FH), a genetic disorder with a prevalence of 0.2 %, represents a high risk factor to develop cardiovascular and cerebrovascular diseases. The majority and most severe FH cases are associated to mutations in the receptor for Low Density Lipoproteins (LDL-r), but the molecular basis explaining the connection between mutation and phenotype is often unknown, which hinders early diagnosis and treatment of the disease. We have used atomistic simulations to explore the complete SNP mutational space (227 mutants) of the LA5 repeat, the key domain for interacting with LDL that is coded in the exon concentrating the highest number of mutations. Four clusters of mutants of different stability have been identified. The majority of the 50 FH known mutations (33) appear distributed in the unstable clusters, i.e. loss of conformational stability explains 2/3 of FH phenotypes. However, 1/3 of FH phenotypes (17 mutations) do not destabilize the LR5 repeat. Combining our simulations with available structural data from different laboratories, we have defined a consensus binding site for the interaction of the LA5 repeat with LDL-r partner proteins and have found that most (16) of the 17 stable FH mutations occur at binding site residues. Thus, LA5-associated FH arises from mutations that cause either loss of stability or a decrease in domain's binding affinity. Based on this finding we propose the likely phenotype of each possible SNP in the LA5 repeat and outline a procedure to make a full computational diagnosis for FH. [less ▲]

Beginning with the assumption that young children are capable of producing unprecedented knowledges about science phenomena, this paper explores the complexities of children’s inquiries within open-ended investigations. I ask two central questions: (1) how can we (teachers, researchers, and children themselves) use and build upon children’s explorations in science in practice? and (2) what pedagogical approaches can position children as experts on their experiences to facilitate children’s sense of ownership in the process of learning science? Six vignettes from a Kindergarten classroom are analyzed to elaborate the central claim of this work, which is that when children are engaged in collaborative open-ended activities, science emerges from their interactions. Open-ended structures allowed for teachers and children to facilitate further investigations collaboratively, and participatory structures mediated children’s representations and explanations of their investigations. Evidence of children’s interactions is used to illustrate the complexities of children’s explorations, and pedagogical approaches that create the spaces for children to create knowledge are highlighted.

Previous studies that describe the existence and dimensions of the digital divide call attention to the potential negative consequences of not having access to a computer and not being online. Missing from these studies, however, is a more thorough investigation of how the effect of race/ethnicity on computer ownership is mediated by associated factors and how these effects have changed across time. The current study attempts to fill these gaps. Using Current Population Survey data, from 1984 to 2003, I estimate a series of logistic regression models on computer ownership at the household level. After controlling for demographic, household composition, and socioeconomic variables, the gap between Black and Hispanic households in relation to White households remains statistically significant. For Asian households, the racial effect is explained by the variables in the models. The implications of these findings are discussed and suggestions are made for future research. [less ▲]

Archivists working with legal deposit must work with a definition of their national web, which may be based on the ccTLD, but also on domain registration, the location of servers and/or other criteria. Scholars must then interpret those archives in the light of those definitions. Others studying nations without such legal frameworks face different challenges in working with archives compiled on a selective basis, or with materials held in multiple archives. This panel brings together several of the contributors to ‘The Historical Web and Digital Humanities: The Case of National Webs’, (Routledge, 2019, edited by Niels Brügger and Ditte Laursen). After briefly summarising their own contribution, they will discuss together the particular challenges of defining and then collecting the national web, and on studying the national web with the resulting archives. The panel will be introduced, moderated and concluded by Ditte Laursen & Valérie Schafer. Ditte Laursen (Royal Library, Denmark) investigates how a corpus to support historical study of a national web can be established within national web archives, which usually hold several versions of the same web entity. Examining different datasets from the Danish national web archive 2005–2015, and the different ways these are handled, she demonstrates significant differences between results, with possible implications for research. The Belgian web is currently not systematically archived. Friedel Geeraert (State Archives and Royal Library of Belgium) presents PROMISE, a research project into the feasibility of a sustainable web archiving service for Belgium. She traces the history of the Belgian web from the establishment of the .be domain in 1988 to the present, situating it in its historical, political, and legal context. Kees Teszelszky (KB – National Library of the Netherlands) explores the research opportunities of the Dutch national web for future historians by describing the development and unique characteristics of the Dutch national web. Using traditional historical methods and web archaeology, much historic data can be reconstructed, even though the KB web archive started only in 2007. Valérie Schafer (University of Luxembourg) draws on the experience of the French Web90 project to show the approaches, tools and methodologies used to sketch a broad historical picture of the French web during the 1990s, and the challenges the project faced. No organisation has formal, ongoing responsibility of whole-domain archiving for .eu, one of the largest and most popular European top-level domains, Daniel Gomes (Arquivo.pt) presents an overview of archiving activities related to .eu, including the only known effort to date to archive the entire domain. He also proposes a number of options for sustainable, long-term archiving for .eu. [less ▲]

Trait self-control (TSC) has been conceptualized as a general and abstract ability to exert self-regulation across multiple domains that has mostly beneficial effects. However, its relationship to situational depletion of self-regulatory resources has received little attention. We systematically explore the interplay of trait and situational self-control in two studies (total N = 264). In contrast with a positive view of TSC, the results show greater ego depletion effects for high (vs. low) self-control abilities across such diverse domains as candy consumption (Study 1), risk-taking behaviour (Study 2) and achievement motivation (Study 2). It is proposed that these ironic effects are attributable to high-TSC individuals' less frequent active inhibition of impulses in everyday life and their resulting lack of experience in resisting acute temptations. A third study (N> = 358) corroborated this general reasoning by showing that TSC is indeed associated with less frequent impulse inhibition in daily routines. Our data point to a downside of dispositional self-control in ego depletion paradigms. Other explanations and potential future avenues for resolving inconsistent findings across the literature are discussed. [less ▲]

We investigate the existence of local (i.e. within-country) and global (i.e. between-country) knowledge spillovers within a single analytical framework. Our analysis is based on an exhaustive database on Irish manufacturing plants covering the period 1986-1994 and focuses on the impact of R\&D spillovers on productivity. Our results show that while the R\&D undertaken by multinationals active in Ireland has had no significant impact on local plants’ productivity, these multinationals have, nevertheless, through their presence, favoured the diffusion of global R\&D spillovers. We furthermore show that while domestic plants benefited from R\&D spillovers emanating from other domestic firms, these spillovers had a much more limited spatial scope compared to multinational-presence induced spillovers. Foreign affiliates in turn, have directly gained from the size of the R\&D stock in their origin country, but there is no evidence that foreign affiliates located in Ireland had benefited from local R\&D spillovers.
