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 ▲]

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.

We report on the analysis of 214 kb of the parasitic eubacterium Mycoplasma capricolum sequenced by genomic walking techniques. The 287 putative proteins detected to date represent about half of the estimated total number of 500 predicted for this organism. A large fraction of these (75%) can be assigned a likely function as a result of similarity searches. Several important features of the functional organization of this small genome are already apparent. Among these are (i) the expected relatively large number of enzymes involved in metabolic transport and activation, for efficient use of host cell nutrients; (ii) the presence of anabolic enzymes; (iii) the unexpected diversity of enzymes involved in DNA replication and repair; and (iv) a sizeable number of orthologues (82 so far) in Escherichia coil. This survey is beginning to provide a detailed view of how M. capricolum manages to maintain essential cellular processes with a genome much smaller than that of its bacterial relatives. [less ▲]

The aim of this study is to examine the relationship between banking sector reform and bank performance –measured in terms of efficiency, total factor productivity growth and net interest margin– accounting for the effects through competition and bank risk-taking. To this end, we develop an empirical model of bank performance, which is consistently estimated using recent econometric techniques. The model is applied to bank panel data from ten newly acceded EU countries. The results indicate that both banking sector reform and competition exert a positive impact on bank efficiency, while the effect of reform on total factor productivity growth is significant only toward the end of the reform process. Finally, the effect of capital and credit risk on bank performance is in most cases negative, while it seems that higher liquid assets reduce the efficiency and productivity of banks. [less ▲]

We propose an agent-based dynamics which leads an urban system to the standard equilibrium of the Alonso, Muth, Mills (AMM) framework. Starting for instance from a random initialization, agents move and bid for land, performing a kind of local search and finally leading the system to equilibrium rent, density and land use. Agreement with continuous analytical results is limited only by the discreteness of simulations. We then study polycentrism in cities with this tool. Two job centers are introduced, and the economic, social and environmental outcomes of various polycentric spatial structures are presented. We also introduce two-worker households whose partners may work in different job centers. When various two-worker households are mixed, polycentrism is desirable, as long as the centers are not too distant from each other. The environmental outcome is also positive, but housing surfaces.increase. (C) 2016 Elsevier Ltd. All rights reserved. [less ▲]

A key challenge in the environmental and exposure sciences is to establish experimental evidence of the role of chemical exposure in human and environmental systems. High resolution and accurate tandem mass spectrometry (HRMS) is increasingly being used for the analysis of environmental samples. One lauded benefit of HRMS is the possibility to retrospectively process data for (previously omitted) compounds that has led to the archiving of HRMS data. Archived HRMS data affords the possibility of exploiting historical data to rapidly and effectively establish the temporal and spatial occurrence of newly identified contaminants through retrospective suspect screening. We propose to establish a global emerging contaminant early warning network to rapidly assess the spatial and temporal distribution of contaminants of emerging concern in environmental samples through performing retrospective analysis on HRMS data. The effectiveness of such a network is demonstrated through a pilot study, where eight reference laboratories with available archived HRMS data retrospectively screened data acquired from aqueous environmental samples collected in 14 countries on 3 different continents. The widespread spatial occurrence of several surfactants (e.g., polyethylene glycols ( PEGs ) and C12AEO-PEGs ), transformation products of selected drugs (e.g., gabapentin-lactam, metoprolol-acid, carbamazepine-10-hydroxy, omeprazole-4-hydroxy-sulfide, and 2-benzothiazole-sulfonic-acid), and industrial chemicals (3-nitrobenzenesulfonate and bisphenol-S) was revealed. Obtaining identifications of increased reliability through retrospective suspect screening is challenging, and recommendations for dealing with issues such as broad chromatographic peaks, data acquisition, and sensitivity are provided.

Dynamic epistemic logic as viewed by Baltag, Moss and Solecki (BMS) and propositional dynamic logic (PDL) offer different semantics of events. On the one hand, BMS adds dynamics to epistemic logic by introducing so-called event models as syntactic objects into the language. On the other hand, PDL has instead transition relations between possible worlds. This last approach allows to easily introduce converse events. In this paper we add epistemics to this, and call the resulting logic epistemic dynamic logic (EDL). We show that BMS can be translated into EDL thanks to this use of the converse operator : it enables us to translate the structure of the event model directly within a particular axiomatization of EDL, without having to refer to a particular epistemic event model in the language (as done in BMS).We show that EDL is more expressive and general than BMS and we characterize semantically and syntactically in EDL this embedding of BMS.
