Migration flows of the 21st century lead to increasingly multilingual societies and entail rapidly evolving language practices. In sociolinguistics and education, there has been a growing interest in exploring these language practices. While most translanguaging studies carried out at school attend to the flexible use of two or more named languages, they only marginally acknowledge the pupils’ semiotic repertoires. Meaning making, however, occurs across and beyond languages. In this presentation, I will provide insight into the meaning-making processes of a newly arrived pupil in Luxembourg. As the instruction of French, German and Luxembourgish accounts for more than 40% of all curricular time, it can be difficult for newcomers to access the curriculum if they have to learn two or even three languages. This raises the question if and to what extent pupils draw on their resources to engage with the curriculum. My doctoral research tackles the following question: In what ways, to what extent and for what purposes do four multilingual fourth graders of different backgrounds deploy and develop their semiotic repertoires in interaction with their peers and teachers? To address that question, I visited two primary schools in Luxembourg where I observed, took field notes and video-recorded the pupils’ interactions as well as their use of multilingual and multimodal resources. A selection of recordings was discussed with the focal pupils in stimulated recall interviews. Observations, video-recordings and interviews were transcribed and analyzed with thematic analysis (Braun and Clarke 2013), multimodal interaction analysis (Norris 2004) and sociocultural discourse analysis (Mercer 2004) respectively. This presentation is based on the classroom interactions in one of the investigated schools and foregrounds one of the main findings: the pupils aligned their translanguaging practices to those of their peers. They adapted their language use to the interlocutor, orchestrated their semiotic resources in the same way as their peers and reproduced the teacher’s translanguaging practice. The study highlights the interconnectedness of classroom and individual practices and draws attention to the importance of resources other than linguistic ones in meaning-making processes at school.

With 35.5 immigrants per 1000 inhabitants, Iceland had the third highest number of immigrants/ inhabitants in Europe in 2017. Until the turn of the century, the foreign population percentage in Iceland was around 2%. In the last 5 years, this percentage has risen steadily to over 10% in 2018. How is this rapid rise in immigration experienced by the host country population? What is the attitude towards this increasingly plurally composed society? The Inclusive Societies – Iceland project investigated both, the immigrants’ situation in Iceland, but also the native populations’ attitude towards immigration and immigrants. It is important to take the host country perspective into consideration, as diversity ideologies will also determine the acculturation options for minorities. A quantitative survey was conducted among 3630 native Icelanders (51.1% women, Mean Age = 50.8, SD = 15.6), spread across all regions of Iceland. The questions covered satisfaction with life in Iceland in different domains but included also specific questions about the attitudes towards immigrants and enquired about contact with immigrants. The results indicate that this culture contact takes place – with over two thirds of participants indicating that they have invited immigrants to their home a few (34.4%) or many times (34.4%). Slightly less participants have been invited to immigrants’ homes (few times 33.6%, often 27.9%). Predictors for openness towards multiculturalism will be presented and discussed. We will also outline the domains with little and considerable variance among respondents concerning cultural practice and attitude to immigration and close with a discussion of policy implications.

In the present survey paper, we give a short, yet exhaustive state-of-the-art about the cyber-security applied to control systems, especially the event-based strategy. Indeed, in the past few years, due to a highest degree of connectivity in modern systems, new related control-specific cyber-physical systems security challengesarise and novel approaches integrating the cyber aspect are developed.Our goal in this paper is then to provide an overview of attack-modeling and security analysis approaches in recent works thatexplore networked control systems subject to cyber-attacks attacks. To this end, we look at the control, estimation, and modeling problems. [less ▲]

In many branches of physics, one must often deal with processes involving a huge number of degrees of freedom. Instead of describing the dynamics of each individual of them, one rather wants to characterize the process of interest via a small set of observ- ables that capture its main features of the process. Even if the microscopic dynamics can be resolved using Newton’s equations of motion, it quickly becomes a computation- ally very expensive calculation to make. It is however much more convenient to come up with a self-consistent equation of motion for the ’global’ observable of interest itself in order to reduce the complexity of the problem. The development of the Mori-Zwanzig formalism in the 1960’s allowed to systematically derive such equations for arbitrary observables in stationary processes. This framework, derived from first principles by means of projection operator techniques, proves the structure of what is now known as the Generalized Langevin Equation, i.e. a stochastic equation of motion which a priori exhibits memory effects in the form on non-localities in time. We propose to extend the formalism and its corollaries to a broad class of out-of- equilibrium processes. We show that the structure of the Generalized Langevin Equa- tion is overall robust but must be adapted to account for the non-stationary dynamics [1,2]. The function that controls memory effects the stochastic term are related through a relation that can be associated to fluctuation-dissipation theorems. This formalism is very convenient to study two-time auto-correlation functions for which we can write a self-consistent differential equation as well. We finally show a new method to evaluate the memory function from numerical or experimental data [3]. [less ▲]

In the past years, several automated repair strategies have been proposed to fix bugs in individual software programs without any human intervention. There has been, however, little work on how automated repair techniques can resolve failures that arise at the system-level and are caused by undesired interactions among different system components or functions. Feature interaction failures are common in complex systems such as autonomous cars that are typically built as a composition of independent features (i.e., units of functionality). In this paper, we propose a repair technique to automatically resolve undesired feature interaction failures in automated driving systems (ADS) that lead to the violation of system safety requirements. Our repair strategy achieves its goal by (1) localizing faults spanning several lines of code, (2) simultaneously resolving multiple interaction failures caused by independent faults, (3) scaling repair strategies from the unit-level to the system-level, and (4) resolving failures based on their order of severity. We have evaluated our approach using two industrial ADS containing four features. Our results show that our repair strategy resolves the undesired interaction failures in these two systems in less than 16h and outperforms existing automated repair techniques. [less ▲]

Conscientiousness and its subfacets are related to multiple learning-related outcomes. MacCann, Duckworth and Roberts (2009) developed a questionnaire measuring seven subfacets of conscientiousness with 59 items. However, the resources required to complete such long scales often renders it unsuitable for large-scale educational assessment. Consequently, an economic and psychometrically sound conscientiousness questionnaire that is specifically customized for this context is needed. We developed and validated a short version of the MacCann et al. (2009) questionnaire. In study 1, French and German adaptations of the questionnaire were administered to a representative dataset comprising all ninth-graders in Luxembourg (N1=6325, Cohort 2017). Using an exhaustive search algorithm, we identified the optimal combination of four items for each subfacet by simultaneously considering three criteria: goodness of fit, factor saturation, and scalar measurement invariance across the German and French versions. In study 2, we validated our short 28-item questionnaire on a second, independent sample comprising 6,279 Luxembourgish ninth-graders (Cohort 2018). A 7-factor model assuming separate factors for each subfacet obtained acceptable fit (CFI=.93, RMSEA=.04, SRMR=.06). The criterion validity for each subfacet was tested by examining the relation to standardized achievement tests (SATs). In study 3, drawing on a dataset of 275 tenth-graders (linked longitudinally with the ninth-grade data from study 1), evidence of predictive validity (i.e., school grades) was examined. The subfacets of industriousness, caution and perfectionism showed the strongest relations with both SATs (study 2) and school grades (study 3). Our study delivered a short, valid and reliable questionnaire for the assessment of seven conscientiousness facets in the educational context. The scale is invariant across the German and French language versions and its brevity makes it suitable for large-scale educational assessment. [less ▲]

Increased migration has led to the formation of culturally diverse societies in most places around the world. Consequently, individuals of different ethnic backgrounds need to find ways of living together. Multiculturalism as an ideology and policy framework proposes several strategies to deal with increasing diversity and to improve intergroup relations in multicultural contexts. Berry (2016) emphasizes two important aspects of multiculturalism: a) diversity, the presence of ethnocultural diversity in the population and b) equity, the right for equal participation of all cultural groups in the society. Both diversity and equity are necessary conditions for the success of multicultural policies. Culturally heterogeneous communities that do not support inclusion and equitable participation of all groups, face the negative consequences of segregation. In line with this notion, an international research consortium developed a revised version of the Multicultural Ideology Scale (Berry & Kalin, 1995) to assess support for cultural diversity. The scale aims to distinguish various attitudinal dimensions of multiculturalism, relevant to the acceptance and social inclusion of different ethnocultural groups: Cultural Maintenance, Equity/Inclusion, Social interaction, Essentialistic Boundaries, Extent of Differences, and Conflictual Relations. The present study is part of this cross-cultural research project, which aims to develop and test the psychometric properties of the scale in different language versions and cultural contexts. The survey will be administered to a large sample of native German citizens with different demographic characteristics. We aim to understand the attitude of native citizens towards cultural diversity and their willingness to interact with members of ethnic minority groups. We will also investigate the relationship between multicultural attitudes and individual difference variables, such as ethnic group attachment and social dominance orientation. Findings from all the country studies in the project will enable us develop a universal measure of multicultural attitudes that can be applied in multiple groups and contexts. [less ▲]
