The legal framework in Luxembourg does not provide a specific legal status for unaccompanied minors (hereafter UAM), which is why the large majority of them apply for international protection. This allows them to stay in the country and to benefit from social and legal assistance, as well as from accommodation. Cases of UAMs presumed or identified victims of human trafficking are rare in Luxembourg. Overall, specific legal frameworks exist according to the status of the UAM: The Law on Asylum, the Law on Immigration and the Law on victims of trafficking in human beings. This framework is completed by general provisions of the Youth Protection Law, which applies to all minors independent of their immigration or legal status. Until the influx of applicants for international protection in 2015 and 2016, the phenomenon of unaccompanied minors has been relatively small in Luxembourg. Particularly 2015 was marked by a high number of UAMs applying for international protection, with 102 introductions of applications compared to 31 applications in 2014. Since, the number of applications has stabilised over the last two years, with 51 applications in 2016 and 50 applications in 2017. In 2015, Afghanistan and Albania were the leading countries of origin of UAMs. In 2016, Afghanistan was still the leading country of origin, followed by Morocco. In 2017, the profiles of the UAMs changed again, with Albania and Morocco as leading countries of origin. In Luxembourg, UAMs are predominantly boys and a large majority is close to the age of majority, or have already reached the age of majority, when a final decision on their application for international protection is issued. However, the Directorate of Immigration reported that they were confronted with a new phenomenon in 2017, namely the arrival of very young UAMs aged between 12 and 14. Every UAM, whether s/he files an application for international protection or not, will be assigned an ad-hoc administrator as soon as possible in order to assist him/her in all legal proceedings. In addition to the designation of an ad-hoc administrator, the organisations that accommodate the UAMs applying for international protection usually request the guardianship (either institutional or personal guardianship) of the UAM who has introduced his application. Different from the ad-hoc administrator, the guardian is assisting and supporting the UAM in all daily life affairs, such as social guidance, integration, education, medical care, acquisition of language skills, leisure activities, etc. In regard to education, the overall aim in Luxembourg is to integrate migrant children, independent of their immigration status, into the general educational system as soon as possible. The latter has experienced a diversification of its offer with a number of specialised measures and services. Together with leisure and extracurricular activities, school is considered to be one of the main contributors to the overall well-being and integration of UAMs into the Luxembourgish society. There are no integration measures that specifically target UAMs. There are no specific transition measures or procedures for UAMs who are approaching their majority, neither in regard to the accommodation and guardianship arrangements, nor in the general context of integration. The organisations responsible for the accommodation and care of the UAMs provide them with a supervision and support according to their specific individual needs. This is also true for the respective legal framework of the UAM, including eventual extensions of residence permits. The return of UAMs is considered to be rare in the Luxembourgish context. As mentioned earlier, this is related to the fact that the large majority of UAMs applying for international protection are close to the age of majority or have already reached majority when a final decision on their application is issued. Furthermore, although foreseen by the Immigration Law, Luxembourg does not carry out forced returns of persons considered to be unaccompanied minors. The International Organisation for Migration (IOM), responsible for (assisted) voluntary returns, reported that they have approximately one voluntary return of an UAM every two years. In 2017, following the recommendation of the evaluation of the Schengen acquis in the area of return in Luxembourg, the government adopted the creation of a new commission with the function of assessing the best interest of the child in the context of return of UAMs. This commission entered into force at the beginning of 2018 and is composed of members of the prosecution service, the National Childhood Office (ONE), the Luxembourg Reception and Integration Agency (OLAI), and finally the Directorate of Immigration, which is chairing the commission. In addition, the ad-hoc administrator is invited to attend the commission meeting for the minor s/he represents. Based on the elements of his/her application, an individual opinion assessing the best interest of the child, in the context of his/her return, will be given for each minor. One of the major reported challenges is the appointment of legal representatives of UAMs (ad-hoc administrator and guardian), as well as the lack of precision of the legal provisions in this context. In the context of return, the Directorate of Immigration reported that they are faced with challenges in regard to getting in contact with the respective countries of origin as well as in regard to cases of applicants not telling the truth. One of the main good practices that has been identified by a number of stakeholders are the new care and accommodation arrangements, allowing to house UAMs in specifically dedicated reception facilities with a 24/7 supervision, depending on the availability of these facilities. In the same context, it was reported that it is of great importance to provide the minors with an environment of trust and support, to listen to them and to reassure them in order to be able to understand their current situation. Particularly the approach of supporting them in elaborating a life plan or life project (“projet de vie”) is considered as being very important for the stability and general well-being as well as for the integration of the UAMs. In addition, it is also important to support them in other matters of integration, such as education, acquisition of language skills, extracurricular activities, etc. In the context of return, Directorate of Immigration reported the newly concluded agreement with IOM in order to conduct family assessments of UAMs in the countries of origin as a good practice. On the one hand, this assessment is one element that will be taken into consideration in the examination of the application of the minor. On the other hand, it helps in assessing the best interest of the child in the event of a return if the application is rejected. [less ▲]

This study exposes post-war voters’ fiscal liberalism using individual level and aggregate-level data covering a decade and a half of local electoral competition in post-war Croatia. Aggregate-level analysis shows Croatian voters’ fiscal liberalism to be conditional on their communities’ exposure to war violence: greater exposure to violence leads to greater support for fiscally expansionist incumbents. Individual-level analysis, on the other hand, shows post-war voters’ fiscal liberalism as rooted in their different levels of war-related trauma: more feelings of war-related trauma lead to greater economic expectations from the government. Our analysis also shows that voters’ war-conditioned preferences for fiscally expansionist incumbents show little sign of abating over time – a testament to the challenge presented by post-war recovery, and to the impact war exerts on political life long after the bloodshed has ended.

This thesis investigates Cape Verdean migration trajectories into Luxembourg from a multisited sociolinguistic point of view. Approaching migration as both emigration and immigration, the thesis examines sociolinguistic aspects of both aspiring and accomplished Cape Verdean migrants to Luxembourg. Based on a narrative and the material ethnography, the thesis seeks to understand migration and its inequalities from the colonial past to the current episode of globalisation. As a starting point, the thesis historicises Cape Verdean migration to Luxembourg as initially entangled in colonisation and labour policies. It has shown that, Cape Verdean movements to Luxembourg derived indirectly from Portuguese colonisation and unexpectedly meddled in Luxembourg foreign labour policies during the 1960s and 70s. This thesis explores this entanglement and unexpectedness of migration from the perspective of individual migrants. It explores what happened in between those points of departure and arrival by means of a multisited ethnographic linguistic landscape approach (MELLA). This approach consists of a material and narrative ethnography that studied traces of migrant presences and absences in public and private spaces on both ends of the trajectory. It was found that the linguistic landscape of Cape Verde contained numerous references to Luxembourg (e.g. Avenida Luxemburgo in Santo Antão) and vice versa (e.g. Epicerie Créole in Bonnevoie) and that some participants in the study, like myself, routinely went back and forth, sustaining relationships and engagements in both countries. However, findings also showed how unequal and exclusive South-North mobilities have become. It is obvious that as life in general is, South-North migration is a struggle, with language being a crucial dimension of this struggle. The thesis shows how migration is a struggle from the start in the country of origin with prospective migrants making considerable efforts and investments to travel North, often in vain, and continues to be a struggle for those who succeed to arrive North. Language duties are always demanded and migrants are constructed from a linguistic deficit perspective rather than addressing the systemic and structural conditions that contribute to unequal struggles among migrant groups and between the locals and migrants, intersecting with gender, class and race. This study provides an account of how multilingualism itself is also a struggle for Cape Verdeans, as Luxembourg’s trilingualism is often used as a gatekeeping device and as a proxy for race in a ‘colour-blind’ racism. It is my hope that this first book-length study of Cape Verdean migration to Luxembourg has opened a new empirical field of research, and will be followed by many more studies to come. [less ▲]

En matière d’éducation en général, et plus précisément dans le contexte de l’acquisition de compétences et de connaissances scolaires, on ne cesse de souligner que dans beaucoup de pays il existe des écarts importants entre des élèves en fonction de leur arrière-fond socio-économique, de leur langue maternelle, ou de leur statut de migration. Souvent, cependant, il importe de clarifier quelles pourraient être des caractéristiques qui interagissent avec les variables pré-mentionnées. Cela aiderait à saisir le pourquoi des ces différences et à élucider quelles mesures de soutien pourraient être adoptées. En supposant que la fréquence de lecture puisse avoir un impact important sur le niveau de lecture, nous nous intéressons, dans la présente étude, aux différences en matière de lecture et ce en fonction des différentes caractéristiques socio-culturelles et des habitudes de lecture des élèves. À cet effet, nous aurons recours aux données issues des Épreuves Standardisées de l’année 2016/2017. Tous les élèves du grade 9 de l’enseignement secondaire du Luxembourg y ont participé à des tests de lecture de textes en français et en allemand. En outre, ces mêmes élèves ont été questionnés sur leur arrière-fond socio-culturel, ainsi que sur leurs habitudes de lecture. Plus précisément, il leur était demandé d’indiquer à quelle fréquence ils lisaient différents types de textes en dehors de l’école. Les résultats montrent que les textes en format numérique sont ceux qui sont le plus attrayants pour les adolescents. Cette préférence générale pour des textes numériques se retrouve parmi tous les groupes socio-culturels sans exception. Des analyses de régression mettent en évidence que ce sont surtout le fait et la fréquence de lire des textes narratifs qui ont un impact sur les compétences de lecture, et ce même si on prend en compte les variables d’arrière-fond socio-culturel des élèves. La discussion des résultats mettra d’un côté l’accent sur l’importance de la lecture ainsi que sur les possibilités de stimuler la motivation de lecture auprès des jeunes, mais aussi sur la popularité croissante de textes en format numérique et les conséquences correspondantes.

BACKGROUND AND AIMS: Sexual addiction is a pathological behavior characterized by a combination of excessive sexual desire and impaired ability to control it. Its incidence ranges between 1.2% and 32.2%, although this number may vary depending on the screening tool used. This wide variability is largely due to the use of non-validated instruments (e.g., structural validity relying on exploratory analyses, instruments translated without an additional validation process, or instruments validated in another format). To deal with these limitations, this study tested the psychometric properties of the Spanish paper-and-pencil and online versions of the Sexual Addiction Screening Test (SAST). METHODS: A total of 2,528 participants (1,163 males) completed the Spanish version of the SAST, along with other instruments assessing sexual compulsivity (1,585 = paper-and-pencil, 943 = online). RESULTS: The exploratory factor analysis yielded a four-factor structure explaining 57.39% of the variance for the SAST paper-and-pencil version. This factor structure was then verified for the online version through the use of confirmatory factor analysis [chi(2)(264) = 441.59; chi(2)/df = 1.66; RMSEA = 0.02; CFI = 0.94; IFI = 0.94]. This methodology was also used to support measurement invariance (configural, metric, and scalar invariance) according to gender. The reliability of the total score ranged from .82 to .85. Similarly, correlations with related scales were positive and significant (r between .22 and .71). Temporal stability 1 year after the first application was 0.65 (paper-and-pencil format) and 0.60 (online version). CONCLUSION: These results, together with the absence of questionnaires translated into Spanish to assess this construct, justify the use of the SAST in the evaluation of sexual addiction in Spanish-speaking countries.

We study a supply chain where a retailer buys from a supplier who faces financial constraints. Informational problems about the supplier’s demand prospects and production capabilities restrict her access to capital. By committing to a minimum purchase quantity, the retailer can mitigate these informational problems and expand the supplier’s feasible production set. We assume a newsvendor model of operations and analyze the strategic interaction of the two parties as a sequential game. Key parameters in our model are the supplier’s ex ante credit limit, her informational transparency—which conditions the amount of additional capital released by the commitment—and the demand characteristics of the final market. We show that in equilibrium the supplier can benefit from a lower ex ante credit limit or lower informational transparency. The retailer always benefits from an increase in these parameters. We also indicate limits to the commitment approach: under certain conditions, the retailer may prefer to relax the supplier’s financial constraint by adjusting the wholesale price, or a combination of wholesale price and commitment. Our study provides a novel perspective on capital market frictions in supply chains. The e-companion is available at https://doi.org/10.1287/opre.2018.1727. [less ▲]

In this study, conductive carbon nanofibers (CNFs) were dispersed into epoxy resin and then infused into glass fiber fabric to fabricate CNF/glass fiber-reinforced polymer (GFRP) laminates. The electrical resistance and strain of CNF/GFRP laminates were measured simultaneously during tensile loadings to investigate the in situ strain and damage monitoring capability of CNF/GFRP laminates. The damage evolution and conduction mechanisms of the laminates were also presented. The results indicated that the percolation threshold of CNFs content for CNF/GFRP laminates was 0.86 wt % based on a typical power law. The resistance response during monotonic tensile loading could be classified into three stages corresponding to different damage mechanisms, which demonstrated a good ability of in situ damage monitoring of the CNF/GFRP laminates. In addition, the capacity of in situ strain monitoring of the laminates during small strain stages was also confirmed according to the synchronous and reversible resistance responses to strain under constant cyclic tensile loading. Moreover, the analysis of the resistance responses during incremental amplitude cyclic tensile loading with the maximum strain of 1.5% suggested that in situ strain and damage monitoring of the CNF/GFRP laminates were feasible and stable.

Human adults have a rich visual experience thanks to seeing human faces since birth, which may contribute to the acquisition of perceptual processes that rapidly and automatically individuate faces. According to a generic visual expertise hypothesis, extensive experience with nonface objects may similarly lead to efficient processing of objects at the individual level. However, whether extensive training in adulthood leads to visual expertise remains debated. One key issue is the extent to which the acquisition of visual expertise depends on the resemblance of objects to faces in terms of the spatial configuration of parts. We therefore trained naive human adults to individuate a large set of novel parametric multipart objects. Critically, one group of participants trained with the objects in a "facelike" stimulus orientation, whereas a second group trained with the same objects but with the objects rotated 180 degrees in the picture plane into a "nonfacelike" orientation. We used a fast periodic visual stimulation EEG protocol to objectively quantify participants' ability to discriminate untrained exemplars before and after training. EEG responses associated with the frequency of identity change in a fast stimulation sequence, which reflects rapid and automatic perceptual processes, were observed over lateral occipital sites for both groups before training. There was a significant, albeit small, increase in these responses after training but only for the facelike group and only to facelike stimuli. Our findings indicate that perceived facelikeness plays a role in visual expertise and highlight how the adult perceptual system exploits familiar spatial configurations when learning new object categories.

In this study, embedded strain sensors based on the principle of piezoresistivity were fabricated by epoxy-based composites filled with different contents of carbon nanofibers (CNFs). The piezoresistive performances and relevant parameters including gauge factor, linearity, repeatability and hysteresis of these sensors were investigated. A compensation circuit was proposed to eliminate the influence of temperature on sensing signals of the sensors. The CNFs/epoxy sensors were embedded into concrete cylinders to monitor their compressive strains under monotonic and cyclic loadings, thereby assessing practical applications of the CNFs/epoxy sensors as strain sensors for monitoring concrete structures. The results indicate that the sensors containing 0.58 vol% of CNFs, which have a gauge factor of 37.1, a linearity of 5.5%, a repeatability of 3.8% and a hysteresis of 6.3%, exhibited better piezoresistive performance compared to those containing 0.29 vol% of CNFs. The calibration and monitoring curves exhibited a consistent variation trend when the cylinders embedded with sensors were subjected to monotonic and cyclic loadings. This demonstrates that the CNFs/epoxy sensors have considerable potential to be used as embedded strain sensors for structural health monitoring of concrete structures. [less ▲]
