This paper seeks to show how language, combined with other social variables, exacerbates migrants’ and their descendants’ struggles at school and beyond in Luxembourg. To a certain extent, the official trilingualism of Luxembourg – French, German and Luxembourgish – corresponds to an ‘elite multilingualism’ (Garrido 2017; Barakos and Selleck 2018) which defines who can access certain resources, e. g. education, work etc., and who can be left playing catch-up. The latter are those migrants who I here conceive as multilinguals on the margins. The elitist system is a form of domination and power over those whose language repertoire is less valued. Migrants’ disadvantage is further impacted by other indicators of their identity that can go beyond their educational qualifications and language repertoire per se, such as their country of origin, ethnicity, race, gender, citizenship etc. Language intersects with other forms of disadvantage or privileges. From an ethnographic sociolinguistic perspective, drawing on interviews and participant observations, this paper will illustrate this intersection of language, race and ethnicity, and struggles from the ground-level educational realities and aspirations of Cape Verdean migrants and their descendants in Luxembourg. This helps cast light on the social organisation in Luxembourg and understand the effects of multilingualism in creating ‘abyssal lines’ (Santos 2007) between the nationals, certain European migrants, Lusophone and African migrants in terms of social and economic mobility.

Following the footsteps of Germaine de Staël, Benjamin Constant and especially Chateaubriand, pioneers of the modern lampoon, Paul-Louis Courier turns it into a codified and stabilized genre, with its own rhetoric, its own images and its own protagonists (particularly the « I » used by the pamphleteer). However, for the pamphleteer, making the author the main centre of interest implies justifying his writings and explaining the way he can speak on the people's behalf. Studying the lampoon and the metadiscourse relating to it implies therefore opening some sociological horizons : the lampoon emphasizes the social background of the pamphleteer, of his characters and of his readers. Considering these factors, our article aims at comparing the sociological component in Courier's and Tillier's writings, intending to assert exactly how popular 19 th Century-France lampoons are, from a sociological and a rhetorical standpoint.

The concept of geostationary VHTS (Very High Throughput Satellites) is based on multibeam coverage with intensive frequency and polarization reuse, in addition to the use of larger bandwidths in the feeder links, in order to provide high capacity satellite links at a reduced cost per Gbps in orbit. The dimensioning and design of satellite networks based on VHTS imposes the analysis of multiple trade-offs to achieve an optimal solution in terms of cost, capacity, and the figure of merit of the user terminal. In this paper, we propose a new method for sizing VHTS satellite networks based on an analytical expression of the forward link CINR (Carrier-to-Interference-plus-Noise Ratio) that is used to evaluate the trade-off of different combinations of system parameters. The proposed method considers both technical and commercial requirements as inputs, including the constraints to achieve the optimum solution in terms of the user G/T, the number of beams, and the system cost. The cost model includes both satellite and ground segments. Exemplary results are presented with feeder links using Q/V bands, DVB-S2X and transmission methods based on CCM and VCM (Constant and Variable Coding and Modulation, respectively) in two scenarios with different service areas.

This paper explores the entanglement of language with issues such as discrimination and the reproduction of social hierarchies. It unpacks this interplay to show how the use and abuse of language serve as the main mechanism of inclusion, exclusion and limitation of migrants in the labour market, contributing to certain migrant groups and their descendants remaining in the bottom stratum of society. It investigates how language use can both empower and disqualify migrants, creating ethnic pools of work. This paper draws on interviews with a successful middle-aged Cape Verdean man, Pedrinhu, to illustrate this language impact. He came to Luxembourg at a young age and his sports skills helped him to be fast-tracked to acquire Luxembourgish citizenship. He talks about his migration trajectories, his sociolinguistic life and his job interactions with Cape Verdean workers at a private employment enterprise where he now holds a high position. He seeks “to empower” Cape Verdean migrants, challenging some of the institutionalised linguistic demands of the state employment agency he collaborates with; at the same time, he is aware of the reproduction of inequality and the ethnic stratification of his enterprise. The paper concludes by highlighting the ambivalences of multilingualism and empowerment interventions in accessing resources, such as work, in the condensed migration contexts of Luxembourg.

In Luxembourgish and Moselle Franconian, as well as in various other German, Swiss German and Dutch dialects, it is possible to assign the feminine and neuter genders to female individuals. The neuter gender of female first names is strongly grammaticalized in both Luxembourgish and Moselle Franconian, so that they mostly trigger the neuter gender on their targets (e.g. definite articles, personal pronouns). At the same time, the use of the neuter gender is not limited to the use of female first names. Rather, personal pronouns can also be used in reference to female appellatives, female kinship terms, and combinations of a female first name with a last name. Moreover, gender assignment is determined by socio-pragmatic factors (e.g. age, familiarity) and shows a high degree of variation in some reference contexts. The aim of the present study is to provide a first major empirical and comprehensive presentation of this phenomenon in both varieties, taking into account different socio-pragmatic factors and various reference contexts. The results are based on quantitative elicited data retrieved from an online survey and audio recordings collected by means of the Luxembourgish language app Schnëssen, as well as qualitative data from structured interviews involving different descriptive tasks. The collection of the data was undertaken at different localities in the area under investigation. While it was found that the use of neuter in Moselle Franconian is more closely tied to the personal relationship between the speaker and the referent, it is partly possible in Luxembourgish to refer to female public figures using neuter forms. Additionally, an apparent-time analysis for Luxembourgish makes it possible to identify differences between the different age groups of the speakers. It becomes apparent that there is a tendency for younger speakers to prefer neutral gender assignment in variable reference contexts. This also applies to exophoric reference contexts to female individuals without a given reference noun, in which neuter seems to become prevalent as a sort of default gender. [less ▲]

Research on education inequalities has long-established the relationship between the social composition of of schools and achievement levels. However, the empirical study of the social processes in choosing schools and their potential effects on achievement inequalities has often been neglected. This article investigates the extent to which such social processes, related to parents’ educational preferences and expectations, influence the development of students’ achievement inequalities throughout their schooling career, through shaping school communities, as a channel of transmission of socioeconomic inequality. Using longitudinal census data from Chile, which allows us to observe students’ achievements between the 4th and 10th grades, we find support for the claim that the development of achievement inequalities operate partly through well-off parents’ educational preferences and expectations. Moreover, these preferences and beliefs explain most of the social composition effect of schools on achievement inequalities. We conclude that choice processes should be considered as an integral part of theories aimed to explain achievement inequalities as a dynamic process. [less ▲]

The main goal of this thesis was to explore the possibility that ferroelectric materials, characterized by a spontaneous and switchable electric polarization, may present topologically non-trivial structures akin to the skyrmions that occur in their ferromagnetic counterparts. The main tool used in the investigation was atomistic simulation based of first-principles effective models (“second-principles methods”), applied to two model systems: ferroelectric PbTiO3 and ferroelectric/paraelectric superlattices made of PbTiO3 and SrTiO3. More precisely, the simulations were used to analyze multidomain configurations in these compounds, motivated by previous reports that they may present non-trivial structural features. The main finding of the thesis is that, indeed, a simple multidomain configuration in PbTiO3 – namely, a columnar nanodomain with polarization opposed to that of its surrounding matrix – is sufficient to generate a dipole texture – associated to the rotation of the polarization at the domain wall between nanodomain and matrix – with the topology of a skyrmion. This constitutes the first prediction of an electric skyrmion in a simple ferroelectric material. Further, it is shown that the properties and topology of this skyrmion can be tuned by external electric and elastic fields, as well as by temperature, obtaining novel effects such as topological and iso-topological phase transitions. Finally, the investigation of the PbTiO3/SrTiO3 superlattices reveals that the skyrmion structures can be obtained as the ground state solution for such systems. This latter study was developed in the context of a collaboration with experimental groups at UC Berkeley and elsewhere, which led to the first experimental confirmation of electric skyrmions. Hence, in conclusion, the theoretical work in this thesis has been an integral part of the discovery of electric skyrmions in ferroelectric materials. [less ▲]

Memory allows us to draw on past experiences to inform behaviour in the present. However, memories rarely match the situation at hand exactly, and new situations regularly trigger multiple related memories where only some are relevant to act upon. The flexibility of human memory systems is largely attributed to the ability to disregard irrelevant, but salient, memories in favour of relevant ones. This is considered an expression of an executive function responsible for suppressing irrelevant memories, associated with the prefrontal cortex. It is unclear to what extent animals have access to this ability. Here, we demonstrate, in a series of tool-use tasks designed to evoke conflicting memories, that chimpanzees and an orangutan suffer from this conflict but overcome it in favour of a more relevant memory. Such mnemonic flexibility is among the most advanced expressions of executive function shown in animals to date and might explain several behaviours related to tool-use, innovation, planning and more.
