The Annual Report on Migration and Asylum presents the statistical trends and developments in migration, asylum and integration, changes in legislation or policies, and it traces significant national debates, which occurred in Luxembourg during the year 2021. Several of the most notable changes and debates in Luxembourg during the year of 2021 were of legislative nature: The Law of 16 June 2021 amending the Immigration Law entered into force on 5 July 2021. This law changes the legislation on immigration, by lightening the administrative burden for third-country nationals, and by altering certain provisions relating to intra-corporate transferees, trainees and family reunification. The Law of 16 June 2021 amending the Asylum Law entered into force on 5 July 2021. This law modifies the remedies available to applicants for international protection (AIPs). It increases their effectiveness and guarantees maximum legal certainty in the context of transfers under the Dublin Regulation, as well as in the case of final decisions to close proceedings on an application for international protection and of decisions to withdraw international protection. Bill 7844 was introduced to Parliament on 15 June 2021 to amend the amended Law of 8 March 2017 on Luxembourgish Nationality (hereinafter Nationality Law) and entered into force on 22 August as the Law of 30 July 2021. According to the Nationality Law, a candidate (a direct line descendant of a Luxembourg ancestor) for the recovery of Luxembourgish nationality must start to (re)claim her/his Luxembourg nationality before the registrar before 31 December 2022. In 2021, three noteworthy bills were introduced to parliament with their legislative procedure still ongoing at the time of writing.On 2 September 2021, the government introduced to Parliament Bill 7877, intending to amend the amended Electoral Law of 18 February 2003, hereinafter the Electoral Law. This bill intends to support political participation of the steadily growing number of non-Luxembourgish residents and it foresees the abolishment of the 5-year residency clause on active and passive voting rights for EU- and non-EU citizens residing in Luxembourg. Further, the date of closure for the registration on the electoral list before the elections for non-Luxembourg citizens to register on the municipal electoral rolls would be reduced from 87 days to 55 days. On 26 November 2021, the Government Council approved a bill proposing to amend the Immigration Law. This bill aims to ensure a more effective management of the removal of third-country nationals illegally residing on the territory by structuring the different categories of removal measures (mesures d’éloignement) in a clear and coherent way. On 19 January 2022 this bill was introduced to Parliament as Bill 7954. Bill 7881 on the exchange of information relating to nationals of countries outside the European Union as well as the European Criminal Records Information System (ECRIS) was introduced to Parliament on 10 September 2021. This system will make it possible to search for entries in the criminal records of third-country nationals against which court decisions have been issued by the criminal courts of other EU Member States. Several developments occurred with respect to integration in 2021. As already noted in the 2020 Annual Report on Migration and Asylum of the EMN Luxembourg, the Government plans to reform the amended Law of 16 December 2008 on the reception and integration of foreigners. Initial accompanying consultations have already been solicited in 2020 and this process continued in 2021. Multiple consultations with stakeholders from civil society, social partners and the municipalities took place and, in this context, the OECD-study “Towards a successful integration process: The functioning of the integration system and its actors in the Grand Duchy of Luxembourg” was published on 25 November 2021. At the beginning of 2021, the Pact of Living Together (Pakt vum Zesummeliewen – PvZ) replaced the Communal Integration Plan (PCI) to create a more dynamic and multi-year integration process for a stronger inclusion of Luxembourg’s municipalities. Continuing education for Luxembourg residents has been made more accessible and additional courses, which are tailored to AIPs and beneficiaries of international protection (BIPs), have been included into the training portfolio of the Adult Education Service (SFA). Luxembourg has initiated the planning process of extending its current public health care system. It is foreseen to offer vulnerable population groups, who have not been covered to date, low-threshold easy access to health care. Further, Luxembourg has been reacting on the changing situation in Afghanistan since the takeover of power by the Taliban in August 2021. Luxembourg has halted decisions on applications for international protection by Afghans until sufficient reliable information will be available. Between the takeover of power through the Taliban in August until the end of 2021, 71 Afghan nationals have been granted international protection. This includes 45 Afghan nationals evacuated from Afghanistan. Luxembourg has further committed to resettle additional people. While the year 2021 continued to be marked by the COVID-19 pandemic, several important developments, such as the availability of vaccines and rapid tests, did redirect pandemic activity on to different paths than in 2020. The focus lay on testing as well as on getting everyone in Luxembourg, including AIPs and persons in a situation of irregular stay, vaccinated. Yet, Luxembourg’s only external border, that is Luxembourg’s international airport, remained closed for third-country nationals. Luxembourg’s entry regulations, which were adjusted multiple times and in a dynamic fashion in line with the evolution of the pandemic, however, created several exemptions that allowed for the entry of certain third-country nationals. As of 22 December 2021, this border closure was extended from 31 December 2021 to 31 March 2022 by means of Grand Ducal Regulation. For more information, please consult the attached report. [less ▲]

Ce rapport décrit les tendances statistiques en matière de migration, d’asile et d’intégration, les changements législatifs ou politiques et retrace les débats nationaux importants qui ont eu lieu au Luxembourg au cours de l’année 2021. Les principaux changements et débats au cours de l'année 2021 étaient de nature législative ; en particulier deux lois ont été adoptées : La loi du 16 juin 2021 modifiant la loi sur l'immigration est entrée en vigueur le 5 juillet 2021. Cette loi modifie la loi sur l'immigration, en allégeant la charge administrative pour les ressortissants de pays tiers, et en modifiant certaines dispositions relatives aux travailleurs transférés intragroupe, aux stagiaires et au regroupement familial. La loi du 16 juin 2021 modifiant la loi sur l'asile est entrée en vigueur le 5 juillet 2021. Cette loi modifie les voies de recours à disposition des demandeurs de protection internationale (DPI). Elle renforce leur efficacité et garantit une sécurité juridique maximale dans le cadre des transferts sous le règlement Dublin, des décisions définitives de clôture de la procédure relative à une demande de protection internationale et des décisions de retrait de la protection internationale. Par ailleurs, la loi du 30 juillet 2021 portant modification de la loi modifiée du 8 mars 2017 sur la nationalité luxembourgeoise (ci-après loi sur la nationalité) est entré en vigueur le 22 août 2021. Selon cette loi, un candidat (descendant en ligne directe d'un ancêtre luxembourgeois) au recouvrement de la nationalité luxembourgeoise doit signer la déclaration de recouvrement de la nationalité luxembourgeoise auprès de l'officier d'état civil avant le 31 décembre 2022. En 2021, trois projets de loi concernant divers volets des politiques d’intégration ou d’immigration ont été déposés à la Chambre des Députés ; la procédure législative de ces trois projets étant toujours en cours au moment de la rédaction du présent rapport. Le 2 septembre 2021, le gouvernement a déposé à la Chambre des Députés le projet de loi n°7877, visant à modifier la loi électorale modifiée du 18 février 2003 (ci-après la loi électorale). Le texte du projet vise à soutenir la participation politique du nombre sans cesse croissant de résidents non luxembourgeois en abolissant la condition de durée de résidence de cinq ans des citoyens de l'UE et de pays tiers habitant au Luxembourg pour pouvoir participer aux élections communales, tant au niveau de l’électorat actif que passif. Par ailleurs, la date de clôture de l'inscription des résidents de nationalité étrangère sur les listes électorales communales est ramenée de 87 jours à 55 jours avant l’échéance électorale. Le 26 novembre 2021, le Conseil de gouvernement a approuvé un projet de loi proposant de modifier la loi sur l'immigration. Ce projet de loi vise à assurer une gestion plus efficace de l'éloignement des ressortissants de pays tiers résidant illégalement sur le territoire en structurant les différentes catégories de mesures d'éloignement de manière claire et cohérente. Ce projet de loi a été déposé à la Chambre des Députés le 19 janvier 2022 sous le n°7954. Le projet de loi n°7881 sur les échanges d’informations relatives aux ressortissants de pays tiers à l’Union européenne ainsi que le système européen d’information sur les casiers judiciaires (ECRIS) a été déposé à la Chambre des Députés le 10 septembre 2021. Ce système permettra de rechercher les inscriptions du casier judiciaire des ressortissants de pays tiers qui ont fait l’objet de décisions de justice de juridictions pénales d'autres États membres de l'UE. Comme déjà indiqué dans le Rapport Annuel sur les Migrations et l'Asile 2020 du EMN Luxembourg, le gouvernement prévoit de réformer la loi modifiée du 16 décembre 2008 sur l'accueil et l'intégration des étrangers (ci-après loi sur l'intégration). Les premières consultations d'acteurs sociétaux ont déjà été réalisées en 2020 et ce processus s'est poursuivi en 2021. De multiples consultations avec les acteurs de la société civile, les partenaires sociaux et les communes ont eu lieu et, dans ce contexte, l'OCDE a publié son étude intitulée « Vers un processus d'intégration réussi : Le fonctionnement du système d'intégration et ses acteurs au Grand-Duché de Luxembourg » le 25 novembre 2021. Début 2021, le « Pakt vum Zesummeliewen » (PvZ) a remplacé le Plan communal intégration (PCI) afin de créer un processus d'intégration plus dynamique et pluriannuel pour une inclusion plus forte des communes luxembourgeoises. La formation continue des résidents luxembourgeois a été rendue plus accessible et des cours supplémentaires, adaptés aux demandeurs de protection internationale (DPI) et aux bénéficiaires de protection internationale (BPI), ont été insérés dans l’offre de formation du Service de formation des adultes (SFA). Le Luxembourg a entamé le processus de planification de l'extension de son système de soins de santé public. Il est prévu d'offrir un accès aux soins de santé aux personnes vulnérables, pas couvertes jusqu'à présent. Le Luxembourg a réagi à l'évolution de la situation en Afghanistan depuis la prise du pouvoir par les Talibans en août 2021. Le Luxembourg a suspendu les décisions concernant les demandes de protection internationale des Afghans jusqu'à ce que des informations suffisantes et fiables soient disponibles. Entre la prise du pouvoir par les Talibans en août et la fin de l'année 2021, 71 ressortissants afghans ont bénéficié d'une protection internationale. Ce chiffre inclut 45 ressortissants afghans évacués d'Afghanistan. Le Luxembourg s'est en outre engagé à réinstaller d’autres personnes. Si l'année 2021 a continué à être marquée par la pandémie de COVID-19, plusieurs développements importants, tels que la disponibilité de vaccins et de tests rapides, ont réorienté l'activité de lutte contre la pandémie sur des voies différentes de celles de 2020. L'accent a été mis sur les tests et la vaccination de tous les Luxembourgeois, y compris les DPI et les personnes en situation de séjour irrégulier. Toutefois, la seule frontière extérieure du Luxembourg, à savoir l'aéroport international du Luxembourg, est restée fermée aux ressortissants de pays tiers (RPT). La réglementation luxembourgeoise en matière d'entrée sur le territoire, a été ajustée à de multiples reprises et de manière dynamique en fonction de l'évolution de la pandémie, tout en prévoyant plusieurs dérogations permettant l'entrée de certaines catégories de ressortissants de pays tiers. Le 22 décembre 2021, un règlement grand-ducal a prolongé cette fermeture de la frontière du 31 décembre 2021 au 31 mars 2022. [less ▲]

The relationships between students and their teachers can impact students’ learning and development. Characterized by emotional warmth or closeness, positive teacher-student-relationships (TSR) can improve a variety of student outcomes. Existing meta-analyses suggest strong links between TSR and students’ peer relations, school engagement, academic achievement, emotions, executive functions, general well-being, and reductions in aggressive or disruptive behaviors. However, this evidence base is scattered, and a comprehensive overview of the TSR-outcome associations integrating academic, behavioral, socio-emotional, and general cognitive outcomes is lacking. Further, researchers have been unequivocal about possible moderators, such as how these relationships change with student age as their relationship to family, peers, and teachers change. Considering these research gaps, we aim to systematically review the meta-analytic literature and examine the following two research questions: Research Question 1: To what extent do existing meta-analyses provide evidence supporting significant relations between TSR and children’s academic, behavioral, socioemotional, motivational, and general cognitive outcomes? (Overall relationship) Research Question 2: To what extent do these relationships vary by the characteristics of the meta-analyses, such as student samples, measurement characteristics, and the quality of the meta-analyses? To address these research questions, we conduct a systematic review of existing meta-analyses, integrating the findings of eligible studies. We will include quantitative meta-analyses with preschool or K-12 samples who have no diagnosed disorder or disability. [less ▲]

The aim of the SIVA project is to investigate differences between schools with stable high value-added (VA) scores to those with low or medium VA scores to learn about their effective pedagogical strategies. We attempt to achieve this goal through classroom observations and questionnaires for students in grade 2, their parents, their teachers, as well as school presidents. More specifically, with the present study we want to learn from target schools with stable positive VA scores – a statistical method usually used to estimate schools' effectiveness. We will use VA modelling constructively to compare those schools identified as highly effective (i.e., with high VA scores) to schools with medium or low VA scores on variables such as pedagogical strategies, student background, and school climate. To this end, a mixed-methods design based on questionnaires, observations, and results from the Luxembourg School Monitoring Programme ÉpStan (LUCET, 2021) will be applied. The content of the investigation is based on a synthesis of models of school learning and quality, focusing on aspects such as school organization or classroom management (e.g., Hattie, 2008; Helmke et al., 2008; Klieme et al., 2001) and is extended by specificities about the Luxembourgish school system, which are not represented in international school learning models (such as the division into two-year learning cycles, the multilingual school setting, and the diverse student population). With the aim to obtain a preferably broad picture, students, parents, teachers, school presidents and regional directors will be investigated. While parents, teachers, school presidents and regional directors can—as adults—fill out questionnaires individually, obtaining the opinion from children at such a young age can be challenging. The SIVA project tackles this issue by choosing item formats that are appealing and understandable for young children (see, e.g.,Lehnert, 2019), as well as by including classroom observations conducted by neutral educational experts (please, find both the questionnaires and observation sheets in the attachments).

On 24 February 2022, the armed forces of the Russian Federation launched an unprovoked full-scale invasion of Ukraine. This was an unprecedented act of aggression against a sovereign and independent country and goes against fundamental principles of international law. It has been strongly condemned by the international community, including the European Union. As of mid-March, over three million Ukrainian and international refugees are fleeing the war to neighbouring EU and third countries (including Moldova). This massive inflow of Ukrainian refugees into the EU resulted in the Council adopting the implementing Decision 2022/382 of 4 March 2022, introducing temporary protection as a means of dealing with the crisis.

In this paper we examine the relationship between ownership concentration and dividend policy for Thai publicly listed companies. High family ownership firms have higher dividend payouts than low family ownership firms, which we interpret to mean high family ownership firms follow a more rational dividend policy. This finding is consistent with the prediction that agency conflicts between the managers and shareholders are lower at firms with a controlling shareholder. The evidence is robust through different econometric specifications, robust when the level used to determine the extent of family ownership (family control) is lowered to 10 percent of the outstanding shares, and robust to the inclusion of the ownership wedge as a proxy for the severity of agency conflicts.

BCH codes are being widely used in commercial NAND flash controllers, and the decoding algorithm based on the Berlekamp-Massey (BM) algorithm is a classic solution for solving the key equation used for error correction. The latency of BM decoding is the bottleneck of the Bose-Chaudhuri Hocquenghem (BCH) decoder when correcting a high number of bit errors. However, the flash memory has an error distribution that degrades with usage: few errors occur in the new memory and a low number of errors occur within a code block. With usage, the system performance degrades and BM decoding needs t iterations in order to correct a larger number t of errors. In an attempt to improve the system performance for high speed applications, early termination of the BM decoding is necessary to overcome this degradation. In this paper, a practical solution for early termination checking for BM algorithm is provided. The analysis of proposed method is presented by means of considering the weight distribution of BCH code and deriving the probability of malfunction as the event of undetectable error. The proposed method is presented to be effective by the numerical results and the probability of malfunction for the proposed method is lower than 10−26. As a result, the FPGA testing on a USB device validate the reliability of the proposed method for applying to a commercial product. [less ▲]

The cross-border study looks at young people who, in retrospect, were granted virtually no consideration in the pandemic. First of all, the authors analyse the impact of the pandemic on vocational training across the German-French border. They base their findings on a number of interviews, which provide insights into the dynamics of cross-border cooperation in the vocational field at a time which was characterised not only by Covid-19, but also by institutional restructuring. The authors then go on to present the results of their own survey of students on bachelor's and master's courses in the border areas of the Greater Region. The survey was coordinated by Saarland University and provides information on the physical and virtual mobility of students, on their social contacts and their counselling and support needs during 2020 and 2021. The results are illustrated with concrete examples from students on the tri-national UniGR master's course in Border Studies. [less ▲]

The European Green Deal and UN Sustainable Development Goals (SDGs) highlight that education, including re-/up-skilling, is crucial in order to transition to environmental sustainability. Education has an essential role to play by supporting citizens in developing the competences needed to live responsibly, change consumption models, design solutions, transform society and shape a green economy. In the context of the EU’s efforts to promote a sustainable and green Europe, the purpose of this study is to map EU Member States’ national and institutional practices, processes, tools and strategies in education for environmental sustainability (EES) at various levels and in different forms of education. The study will help inform the actions of the European Commission with regard to education for environmental sustainability and policy for the implementation of the European Education Area and the European ‘Green Deal’.

The cross-border study looks at young people who, in retrospect, were granted virtually no consideration in the pandemic. First of all, the authors analyse the impact of the pandemic on vocational training across the German-French border. They base their findings on a number of interviews, which provide insights into the dynamics of cross-border cooperation in the vocational field at a time which was characterised not only by Covid-19, but also by institutional restructuring. The authors then go on to present the results of their own survey of students on bachelor's and master's courses in the border areas of the Greater Region. The survey was coordinated by Saarland University and provides information on the physical and virtual mobility of students, on their social contacts and their counselling and support needs during 2020 and 2021. The results are illustrated with concrete examples from students on the tri-national UniGR master's course in Border Studies. [less ▲]

Zielgruppe des Projektes CatMesNEET (Catalogue de mesures pour NEETs) sind Jugendliche und junge Erwachsene mit NEET-Status in Luxemburg. Die Abkürzung NEET steht hier für „Not in Education, Employment or Training“ und meint Jugendliche, die keine Schule besuchen, keiner Arbeit nachgehen und sich nicht in beruflicher Ausbildung befinden.Es besteht kein nationaler Überblick über Zertifikate, die für die Teilnahme an einer Maßnahme vergeben werden. Diese Lücke soll ebenfalls in der Studie geschlossen werden. Zum einen wird erhoben, welche Massnahmen ein Zertifikat vergeben und zum anderen, worauf diese Zertifikate abzielen. In der ersten Feldphase wurde von Jugend- und Sozialarbeitern kommuniziert, dass Zertifikate durchaus einen wichtigen Stellenwert bei der Suche nach einem Ausbildungs- und Arbeitsplatz haben können. Ziel der Studie ist es daher, ein klares und differenziertes Bild der bestehenden Maßnahmen zur Unterstützung der in Luxemburg lebenden jungen Menschen mit einem problematischen NEET-Status im Alter zwischen 15 und 29 Jahren zu geben. Da der Fokus der Forschung auf Maßnahmen für junge Menschen mit NEET-Status liegt, wird auf individueller Ebene angesetzt, nämlich an der jeweiligen Situation der Betroffenen. Dies bedeutet, dass der Frage nachgegangen wird, welche Maßnahmen Jugendlichen helfen können, um ihrem NEET-Status zu überwinden. Es ist allerdings wichtig, darauf hinzuweisen, dass es auch auf einer strukturellen arbeitsmarktpolitischen Ebene Maßnahmen bedarf, die die NEET-Rate erheblich senken könnten. Daher gilt es festzuhalten, dass es sich bei der NEET-Thematik nicht nur um eine Problematik handelt, die auf individueller Ebene gelöst werden kann, sondern dass diese auch Maßnahmen auf struktureller arbeitsmarkt-, sozial-, und bildungspolitischer Ebene verlangt.

This study provides an overview of the current policies and measures in Luxembourg regarding the integration of third-country national migrant women. Luxembourg follows a mainstream approach regarding integration. According to the Law of 16 December 2008 on the integration of foreigners in the Grand Duchy of Luxembourg, integration is a two-way process that includes both the foreigner and the Luxembourgish society, thereby aiming at all non-Luxembourgish nationals (EU citizens and third-country nationals alike), independent of their gender. However, both national and EU funds may finance measures to support the integration of third-country national migrant women. The number of third-country national women in Luxembourg has increased steadily over the last years, representing 8,1% of the total female population in 2020. Most first residence titles issued to third-country national women were based on family reasons. Depending on the reasons for immigration, the most common countries of origin were India, the U.S.A., and China (to pursue remunerated activities), as well as Syria, Eritrea, the Philippines (for ‘other’ reasons, which includes, among others, beneficiaries of international protection), and Brazil (for family reasons). While third-country national women in Luxembourg comprise a diverse population, occupying jobs in both high-skilled and low-skilled employment sectors, they experience several challenges. Despite higher levels of education, they are more exposed to overcrowded housing, lower household income, lower activity rates, and higher unemployment rates than Luxembourgish women. Moreover, third-country national women are less often enrolled on electoral lists for municipal elections than female EU foreigners. Finally, the issue of discrimination towards (female) residents of African descent in Luxembourg has generated debates in recent years. The study also presents three projects specifically addressing third-country national women, which have been identified as examples of good practices in the context of integration of migrant women, namely ‘Le Temps des Femmes’ by Caritas, ‘Concept d’Intégration, d’Accompagnement et d’Orientation (CIAO!)' by Femmes en Détresse, and ‘Intégration par le Sport’ by the municipality of Esch-sur-Alzette.

This study provides an overview of the current procedures and practices regarding the detection, identification and protection of victims of trafficking in human beings from third-countries in Luxembourg. Since 2016, Luxembourg saw a number of significant developments with regard to legislation, institutional and policy reforms, as well as debates and awareness campaigns related to the detection, identification, and protection of (presumed) third-country national victims of trafficking in human beings. These include, among others, several legislative developments strengthening procedural safeguards and the fight against certain forms of exploitation; the establishment of a National Action Plan on ‘Trafficking in Human Beings’ (including a confidential roadmap for relevant stakeholders in the field) and a National Action Plan on ‘Prostitution’ (which also relates to trafficking in human beings); an enhanced cooperation on the Benelux level; the creation of the Search for Fugitives and Victim Protection Unit of the Judicial Police (including reinforcement in 2021); the appointment of contact person for the fight against trafficking in human beings at the Directorate of Immigration and a ‘trafficking’ reference person in each of its departments; the reinforcement of the support for victims of trafficking (including the establishment of a common space (‘INFOTRAITE’) for the two approved assistance services SAVTEH and COTEH); an increase and broadening of the basic and specialised training for various stakeholders; and the organisation of information and awareness raising campaigns. At the same time, the national referral mechanism in Luxembourg has remained the same since its establishment: all stakeholders who detect a (presumed) third-country national victim of trafficking in human beings are obliged to refer cases to the Organised Crime Unit and the Search for Fugitives and Victim Protection Unit of the Judicial Police. Only the Judicial police can formally identify a victim of trafficking and notify the Directorate of Immigration of the Ministry of Foreign and European Affairs in view of issuing a reflection period of 90 days to the third-country national. Before the expiration of the reflection period, the Directorate of Immigration consults with the Police in order to determine whether a residence permit for victims of trafficking in human beings may be issued to the third-country national. For all the details, including challenges and good practices in the area of detecting, identifying, and protecting victims of trafficking in human beings in Luxembourg, have a look at the EMN Luxembourg Study.

Ausgangspunkt des PAN-VAL Projekts „Aktives Altern in Luxemburg“, das in enger Zusammenarbeit zwischen der Universität Luxemburg und GERO durchgeführt wurde, war die Frage, inwieweit soziale Aktivitäten und Angebote von einer diversen Population genutzt werden. In der Studie wurden die Bedürfnisse und Erwartungen von Menschen über 50 (Luxemburger*innen und Nicht-Luxemburger*innen) in Bezug auf ihre sozialen Netzwerke, ihr soziales Eingebundensein, ihre Freizeitaktivitäten innerhalb ihrer Gemeinde und ihr Zugehörigkeitsgefühl sowie ihre Zufriedenheit mit verschiedenen Lebensbereichen untersucht. Gleichzeitig zielte die Studie darauf ab, zu ermitteln, welche Faktoren eine Teilnahme begünstigen und was Menschen daran hindert, an öffentlichen Freizeitangeboten teilzunehmen. In der vorliegenden Broschüre werden die wichtigsten Ergebnisse der quantitativen und der qualitativen Teilstudien zusammengeführt sowie im Anschluss daran Hinweise für die Gestaltung von Angeboten gegeben. Hierbei werden Module präsentiert, um ältere Menschen mit Migrationshintergrund besser einzubeziehen und Dienstleistungen für ein aktives Altern einer immer diverseren Zielgruppe zu entwickeln. Die Broschüre richtet sich damit an alle, die sich mit der Gestaltung von Angeboten für soziale Aktivitäten – für Ältere, aber nicht nur – im Kontext kultureller Diversität befassen. [less ▲]

Le point de départ du projet PAN-VAL « Vieillissement actif au Luxembourg », qui a été mené à bien en collaboration étroite avec l’Université du Luxembourg et GERO, était la question de savoir dans quelle mesure les activités sociales et les offres sont utilisées par une population diversifiée. Dans le cadre de cette étude, les besoins et les attentes de personnes de plus de 50 ans (Luxembourgeois(es) et non-Luxembourgeois(es)) ont été étudiés en ce qui concerne leurs réseaux sociaux, leur intégration sociale, leurs activités de loisir au sein de leur communauté et leur sentiment d’appartenance ainsi que leur satisfaction avec divers domaines de la vie. En même temps, l’objectif de l’étude était de déterminer quels facteurs favorisent une participation et ce qui empêche les personnes de participer aux offres de loisirs publiques. Dans la brochure présente ont été réunis les résultats les plus importants des études partielles quantitatives et qualitatives suivis d’indications pour l’organisation d’off res. On y présentera des éléments afin de mieux intégrer les personnes âgées issues de l’immigration et de mettre au point des services pour un vieillissement actif d’un groupe cible toujours plus diversifié. Ainsi, cette brochure s’adresse à tous ceux qui s’occupent de l’organisation d’offres pour des activités sociales – pour personnes âgées, mais pas uniquement – dans le contexte de la diversité culturelle.

Climate change and ambitious emission-reduction targets call for an extensive decarbonization of electricity systems, with increasing levels of Renewable Energy Sources (RES) and demand flexibility to balance the variable and intermittent electricity supply. A successful energy transition will lead to an economically and ecologically sustainable future with an affordable, reliable, and carbon-neutral supply of electricity. In order to achieve these objectives, a consistent and enabling market design is required. The Kopernikus Project SynErgie investigates how demand flexibility of the German industry can be leveraged and how a future-proof electricity market design should be organized, with more than 80 project partners from academia, industry, governmental and non-governmental organizations, energy suppliers, and network operators. In our SynErgie Whitepaper Electricity Spot Market Design 2030-2050 [1], we argued for a transition towards Locational Marginal Prices (LMPs) (aka. nodal prices) in Germany in a single step as a core element of a sustainable German energy policy. We motivated a well-designed transition towards LMPs, discussed various challenges, and provided a new perspective on electricity market design in terms of technological opportunities, bid languages, and strategic implications. This second SynErgie Whitepaper Electricity Market Design 2030-2050: Moving Towards Implementation aims at further concretizing the future German market design and provides first guidelines for an implementation of LMPs in Germany. Numerical studies –while not being free of abstractions –give evidence that LMPs generate efficient locational price signals and contribute to manage the complex coordination challenge in (long-term) electricity markets, ultimately reducing price differences between nodes. Spot and derivatives markets require adjustments in order to enable an efficient dispatch and price discovery, while maintaining high liquidity and low transaction costs. Moreover, a successful LMP implementation requires an integration into European market coupling and appropriate interfaces for distribution grids as well as sector coupling. Strategic implications with regard to long-term investments need to be considered, along with mechanisms to support RES investments. As a facilitator for an LMP system, digital technologies should be considered jointly with the market design transition under an enabling regulatory framework. Additional policies can address distributional effects of an LMP system and further prevent market power abuse. Overall, we argue for a well-designed electricity spot market with LMPs, composed of various auctions at different time frames, delivering an efficient market clearing, considering grid constraints, co-optimizing ancillary services, and providing locational prices according to a carefully designed pricing scheme. The spot market is tightly integrated with liquid and accessible derivatives markets, embedded into European market coupling mechanisms, and allows for functional interfaces to distribution systems and other energy sectors. Long-term resource adequacy is ensured and existing RES policies transition properly to the new market design. Mechanisms to mitigate market power and distributional effects are in place and the market design leverages the potential of modern information technologies. Arapid expansion of wind andsolar capacity will be needed to decarbonize the integrated energy system but will most likely also increase the scarcity of the infrastructure. Therefore, an efficient use of the resource "grid" will be a key factor of a successful energy transition. The implementation of an LMPs system of prices with finer space and time granularity promises many upsides and can be a cornerstone for a futureproof electricity system, economic competitiveness, and a decarbonized economy and society. Among the upsides, demand response (and other market participants with opportunity costs) can be efficiently and coherently incentivized to address network constraints, a task zonal systems with redispatch fail at. The transition to LMPs requires a thorough consideration of all the details and specifications involved in the new market design. With this whitepaper, we provide relevant perspectives and first practical guidelines for this crucial milestone of the energy transition. [less ▲]

Le Luxembourg reste un pays attractif à l’immigration. Entre 2019 et 2020 la population luxembourgeoise a continué à augmenter principalement en raison de l’immigration nette, passant de 626.108 à 634.730 habitants (+1,4%), mais d’une manière plus discrète que les années précédentes. La part luxembourgeoise représente 52,8% de la population et les ressortissants étrangers 47,2%. La pandémie a dominé la politique en matière d’immigration et asile pendant l’année 2020 et 2021. Ces politiques ont impacté tous les secteurs au Luxembourg y compris les volets de l’immigration et de l’asile. La fermeture des frontières extérieures de l’Union Européenne, la réintroduction temporaire des contrôles aux frontières internes de l’espace Schengen (décrétées par l’Allemagne, la Belgique et la France) et la perturbation du trafic aérien international ont affecté les mouvements migratoires vers et au départ du Luxembourg. La limitation des mouvements des ressortissants pays tiers (RPT) s’est compliquée suite à la déclaration de l’état de crise entre le 18 mars et le 13 mai 2020 et la fermeture des services d’immigration et asile. Néanmoins, afin d’éviter qu’ils ne tombent dans une situation irrégulière, les autorités luxembourgeoises ont étendu la durée de validité des titres et cartes de séjour et des visas de manière automatique. De même, le traitement des dossiers et la prise de décision par la Direction de l’immigration se sont poursuivis sans interruption. L’interdiction d’entrée des RPT (avec des exceptions pour certaines catégories) a été maintenue jusqu’au 30 juin 2021. Une baisse significative du nombre de titres de séjour délivrés, de demandes d'autorisation temporaire de séjour et de visas de court séjour a été constatée, ainsi qu’une diminution de presque 50% des demandes de protection internationale. Le regroupement familial est resté le principal type de titre de séjour en 2020. Les limitations de mouvements ont aussi une incidence sur les transferts sous le règlement Dublin ainsi que sur les retours vers le pays d’origine. Au cours de l’année 2020, le Luxembourg a continué à maintenir ses engagements de solidarité internationale avec la relocalisation et la réinstallation des demandeurs de protection internationale (DPI) puisque 25 personnes (dont 16 mineurs) ont été relocalisées et 14 réinstallées. La réception des DPI s’est poursuivie car l’Office national de l’accueil (ONA) n’a pas fermé ses guichets. Un défi majeur est constitué par les taux d’occupation élevés dans les structures d’hébergement de l’ONA. La crise du logement affecte particulièrement les bénéficiaires de protection internationale (BPI) qui peinent à trouver un logement en-dehors des structures d’accueil réservées en principe aux DPI. Dans ce contexte l’ONA a poursuivi ses efforts à inciter les communes à promouvoir la mise en place de structures d’hébergement pour DPI et/ou de possibilités d’hébergement pour BPI. [less ▲]

Neural networks are becoming increasingly part of today’s software systems. These neural networks are simplified models of the human brain that are mainly capable of learning from large datasets to compute some function based on recognized data. Engineering these datasets and these neural network-based software systems is a complicated and challenging task. Software engineers require methods and tools to engineer these datasets and neural networks for their customers and to satisfy their requirements. In general, they lack methods and tools to support the engineering of dataset and neural networks that satisfy the customer’s requirements. They follow traditional approaches consisting of time-consuming, imprecise and manual activities. Typically, these approaches are not supported by any tool that precisely analyse and specify the neural network’s recognition skills. In our previous work, we have introduced the notion of key-properties for describing the neural network’s recognition skills. In this paper, we define a domain-specific language to support our SEMKIS software engineering methodology for the dataset augmentation to improve network’s key-properties. We present the SEMKIS-DSL for the specification of the key-properties of a neural network. We illustrate the concepts of our DSL with a running example specifying a neural network for recognizing a digital meter counter state. This running example demonstrates a specification of the neural network’s key-properties using the SEMKIS-DSL and a successful improvement of the neural network’s recognition skills. [less ▲]

At least this was the case until 2020, with the recession caused by the COVID-19 pandemic. Not only has it been unique in terms of its origin, but also in terms of its impact on the labour market: for the first time women were significantly more likely than men to be laid off, furloughed or to experience a reduction in working hours.

The unsafety of current design rules for novel types of open-trough deck geometries for the resistance of headed studs in profiled steel sheeting is well known [1] and it was the main reason behind the nomination of CEN/TC250/SC4- Task SC4.T3: “Revised rules for shear connection in the presence of modern forms of profiled sheeting”. During the RFCS research project “DISCCO” (RFCS-CT-2012-00030) [1], a mechanical model was developed on the basis of a large literature study and previous studies [2, 3, 4, 5, 6] while the corresponding design equations were presented by CEN/TC250/SC4.PT3 and further enhanced during the Research Project “ShearCON” of University of Luxembourg. In order to let the current rules of EN 1994-1-1 6.6 (Eq.(2) and (3)) as unchanged as possible, the limits of its suitable field of applicability (Database B1) was investigated thoroughly by means of the statistical procedure of EN 1990 D.8 [7]. The newly proposed equations (Eq. (7) and (8)) apply only to the cases outside these limits (Database B2). In this way, the proposed solution is able to restore the level of safety to its initial value, so that the partial safety factor for the shear connection ϒV=1.25 is adequate. Conversely, the current situation (without including the new design equations) would need a much higher partial safety factor as shown below. [less ▲]

Hardware accelerators are special types of elements designed for boosting the performance of certain application regions requiring large amounts of numerical computations. Several factors contributed to broadening the use and furthering the adoption of these technologies in High-Performance Computing (HPC). One of such is the offered greater computational throughput as compared to stand-alone Central Processing Units (CPUs), which is driven by the highly parallel architectural design of accelerators. This is particularly important in the current era of ever-increasing computational demands featuring high reuse rates of compute-intensive operational patterns. Another contributing factor is that these specialized chips are also capable of delivering much higher compute performance as compared to CPUs under the same power budget, making these technologies even more appealing for system vendors and users. All these led HPC manufacturers and integrators to unleash further the potential of hardware accelerators for delivering the required compute performance more efficiently. In fact, this is one of the main reasons that the current Top500 list [1] continues to be enriched with various accelerated systems. The next generation of HPC systems will also see a considerable amount of accelerator technology used. As a matter of fact, two out of the three European High-Performance Computing Joint Undertaking (EuroHPC JU) [2] pre-exascale HPC sites have already announced that their supercomputers will be equipped with large amount of Graphics Processing Units (GPUs). Thus, in order to achieve a competitive application performance and to be able to use the underlying hardware infrastructure efficiently, HPC application developers should be familiar with various challenges associated with using and orchestrating vast amounts of accelerator devices while being acquainted with the available ecosystem of the supporting tools. This Best Practice Guide (BPG) extends the previously developed series of BPGs [3] by providing an update on new accelerator technologies to further support the European HPC user community in achieving outstanding performance records of their large-scale parallel applications. This guide follows the style of the previously published guide on "Modern Processors" [4], by providing a hybrid approach of a field guide and a textbook. The aim of this BPG is not to replace any of the available in depth textbooks and/or documentations of certain tools, but rather to provide a set of best practices that build upon the available literature and the expertise of authors involved to further ease the process of application porting and performance optimisation. This guide showcases the usability and possibilities of further application tuning given a specific accelerator technology, and does not provide any direct comparisons of different accelerator technologies involved. The guide provides a generic overview on various accelerators and their accompanying programming models/environments and thus should be viewed as complementary to the existing in-depth BPGs provided by hardware vendors that are typically specific to their own product.

Decline in immune function during aging increases susceptibility to different aging related diseases. However, the underlying molecular mechanisms, especially the genetic factors contributing to imbalance of naïve/memory T-cell subpopulations, still remain largely elusive. Here we show that loss of DJ-1 encoded by PARK7 /DJ-1, causing early-onset familial Parkinson’s disease (PD), unexpectedly delayed immunoaging in both human and mice. Compared with two gender-matched unaffected sibling carriers of similar ages, the index PD patient with DJ-1 deficiency showed a decline in many critical immunoaging features, including almost doubled frequencies of non-senescent T cells. The observation of a ‘younger’ immune system in the index patient was further consolidated by the results in aged DJ-1 knockout mice. Our data from bone marrow chimera models and adoptive transfer experiments demonstrated that DJ-1 regulates several immunoaging features via hematopoietic-intrinsic and naïve-CD8-intrinsic mechanisms. Our finding suggests an unrecognized critical role of DJ-1 in regulating immunoaging, discovering a potent target to interfere with immunoaging- and aging-associated diseases. [less ▲]

The COVID-19 pandemic has created profound changes in all areas of migration and asylum. EU Member States and OECD countries have made many efforts to keep the pandemic under control, entailing impacts such as border closures, travel restrictions, and the need to introduce sanitary measures. Beginning with the pandemic’s impact on permits and entry conditions, the Inform reports on contingency measures to keep systems operational and to mitigate the impacts on migrants and citizens to the extent possible. For instance, the reduction of in-person immigration related services was largely replaced by electronic or postal communication to ensure continuity in processes. In EU Member States and Norway, the automatic extension of residence permits or the removal of the obligation to leave in some cases, were some of the measures taken to reduce the impact of COVID-19. Most EU Member States provided financial support for migrant workers affected by the pandemic, either due to unemployment or loss of income, and made COVID-19 related healthcare services available to all migrants. Although restrictions were imposed on the admission of migrants, continued admission was granted for jobs deemed essential to meet labour market needs, notably in areas of health, agriculture, and transport. New digital tools have been critical in providing asylum and migration services, although the Inform notes that it has also raised new challenges. In the area of asylum, for instance, providing effective and fair application and appeals processes has become more complicated by having remote interviews, and depends largely on the applicants’ ability to use and access electronic means. Both the requests for asylum and the number of returns carried out have reduced in 2020 as a result of the pandemic. The landscape also changed for international students, where in-person attendance was discouraged if not suspended altogether. Many students returned home, and in some cases, were able to continue their studies remotely, while processes to renew residence permits were moved online. The joint research shows that public authorities have acted swiftly to introduce new measures or adapt their systems to confront the migration challenges caused by the pandemic, or in some cases, to simply continue to use pre-existing on-line systems. While the long-term impacts are hard to predict, the last chapter of the inform looks towards future migration policies and how these might be shaped in the context of the digitalisation of migration management, the need for bio-secure borders, and the expansion of teleworking digital nomads. The European Asylum Support Office (EASO) and the European Border and Coast Guard Agency (FRONTEX) provided inputs to the publication. [less ▲]

The main objective of this study of the European Migration Network is to provide objective and reliable information about the usage of detention and alternatives to detention in international protection and return procedures in Luxembourg. Luxembourgish legislation, namely the amended Law of 29 August 2008 on Free Movement of Persons and Immigration (Immigration Law) and the Law of 18 December 2015 on International Protection and Temporary Protection (Asylum Law), foresees three alternatives to detention: - Alternative 1: Reporting obligations, which includes the obligation to surrender a passport, travel document or identity document; - Alternative 2: Home custody (+ electronic monitoring, if necessary); - Alternative 3: Deposition of a financial guarantee of 5.000€. In principle, the assessment between detention or alternatives to detention is made at the same time as when the grounds for detention are considered, as long as the Directorate of Immigration, as the responsible authority, has all the necessary information to decide if an alternative to detention can be ordered. Furthermore, the possibility to impose an alternative to detention is in principle systemically considered, as both relevant laws foresee that the detention decision is ordered in writing by the Minister on the basis of a case-by-case assessment, where necessary and if other less coercive measures cannot be effectively applied. Grounds for detention are generally rejected in favour of an alternative to detention if the person concerned falls within the category of vulnerable groups and if person is able to proof effective guarantees of representation to prevent the risk of absconding. This latter obligation on the third-country national to revert the legal presumption that there is a risk of absconding remains the main challenge because effective guarantees of representation are not defined by law. This is particularly challenging in the context of return procedures, where this legal presumption exists in nearly all cases where a third-country national has no valid identity, travel or residence documents. In the absence of such effective guarantees of representation, the Minister in charge of Immigration and Asylum generally does not make the decision to apply an alternative to detention. Consequently, the research in the context of this study has shown that alternatives to detention are only rarely used in Luxembourg, with the important exception of home custody in the Emergency Housing Structure of Kirchberg (‘Structure d’hébergement d’urgence Kirchberg’ – SHUK). The SHUK serves as a semi-open return facility for applicants for international protection and irregularly staying third-country nationals whose fingerprints have already been registered in Eurodac by another Member State and are therefore likely to be transferred to that Member State, in accordance with the Dublin III Regulation. A placement at the SHUK corresponds to home custody. The rare use of alternatives to detention also results in the fact that there is generally not much data available in this regard, with the important exception of home custody in the SHUK, which is more widely used.

Der Bericht gibt Auskunft über Gesundheit und Wohlbefinden der Schüler im Jahr 2018 in ihrem sozialen Kontext. Darüber hinaus informiert er, wie sich die entsprechenden Indikatoren von 2006—2018 in Luxemburg entwickelt haben. Verbesserungen gab es vor allem beim Gesundheitsverhalten — die Schüler rauchen und trinken weniger, sie putzen sich häufiger die Zähne und essen mehr Obst und Gemüse. Verschlechterungen betreffen die mentale Gesundheit: Die Schüler haben häufiger psychosomatische Beschwerden und sie fühlen sich häufiger von der Schularbeit gestresst. Des Weiteren sind die Schüler häufiger übergewichtig und sie sind seltener körperlich aktiv. Der Bericht zeigt auch, dass Gesundheitsrisiken mit soziodemografischen Merkmalen zusammenhängen, wie u. a. dem Geschlecht, dem Alter, dem Wohlstand und dem Migrationshintergrund. So verhalten sich Mädchen zwar häufig gesundheitsbewusster als Jungen, aber dennoch schätzen sie ihren Gesundheitszustand schlechter ein und sie haben mehr Stress und sie sind häufiger von multiplen psychosomatischen Beschwerden betroffen. Aus Clusteranalysen geht hervor, dass es typische Konstellationen von Gesundheitsverhaltensweisen gibt, die zudem mit soziodemografischen Merkmalen sowie Übergewicht, Stress und der Lebenszufriedenheit zusammenhängen.

2020 was a challenging year for everyone that will stay in our memory. The pandemic disrupted our economies, societies, and all our best laid-out plans. However, COVID-19 also taught us several lessons for the future, in particular the (real) necessity to adapt, to be nimble and to expect the unexpected while supporting cutting-edge excellence in science with the best performing and most flexible tools to unleash research potential. One thing is certain - the strategic developments for accelerated digitalisation and the role that HPC will play to ensure a smarter and more connected University will be in focus in 2021 and the years to come. 2020 was thus a very fruitful and productive year for the ULHPC team which has seen unprecedented changes and challenges.

The eXtended Discrete Element Method (XDEM) is an extension of the regular Discrete Element Method (DEM) which is a software for simulating the dynamics of granular material. XDEM extends the regular DEM method by adding features where both micro and macroscopic observables can be computed simultaneously by coupling different time and length scales. In this sense XDEM belongs the category of multi-scale/multi-physics applications which can be used in realistic simulations. In this whitepaper, we detail the different optimisations done during the preparatory PRACE project to overcome known bottlenecks in the OpenMP implementation of XDEM. We analysed the Conversion, Dynamic, and the combined Dynamics-Conversion modules with Extrae/Paraver and Intel VTune profiling tools in order to find the most expensive functions. The proposed code modifications improved the performance of XDEM by ~17% for the computational expensive Dynamics-Conversion combined modules (with 48 cores, full node). Our analysis was performed in the Marenostrum 4 (MN4) PRACE infrastructure at Barcelona Supercomputing Center (BSC). [less ▲]

Undocumented Migrants (UDM) belong to the most vulnerable groups in times of global emergency situations. COVID-19 does hit hardest the most vulnerable groups and it is important to create an evidence base to guide policy making. The Center for Health and Migration, Vienna, has initiated a stock-taking of national regulations concerning access to health and social care for UDM. The initiative aims to create a landscape of policy frameworks to inform policy making and practice development. National experts on health and migration are contacted and asked to provide information on the respective legal frameworks in the following categories: work, housing, compulsory education, social welfare, and health. A validated template is used for data collection. [less ▲]

There is a great discrepancy between the omnipresent demands for inclusion published by official bodies and ministries and the actual participation of people with disabilities in social life. The policy cultivates the rhetoric of inclusion in programmatic and conceptual formulations, while at the same time maintaining or even expanding separative institutions for those that are considered not to be eligible for inclusion in the fields of education and employment (see competence centres in education and ‘inclusion’ in sheltered workshops, or the persistent exclusion of persons under guardianship from the right to vote). Inclusion is viewed primarily from an economic and neo-liberal perspective, without questioning the basic principles of a meritocratic society oriented towards proven performance. Performance appraisals, especially in the area of education and work, are largely based on the performance demanded and shown without sufficiently taking into account the way the performance is achieved. In the educational sector, the incompatibility of introducing educational standards and achieving full inclusion is not recognised. Separating establishments are renamed to inclusive settings without any fundamental reorientation. The former regional special schools for pupils with cognitive impairments were re-branded as competence centres for intellectual development. With the introduction of the competence centres, no longer official figures are published regarding pupils who are taught separately. There are also no official figures on how many pupils were assigned to the competence centres from regular schools and vice versa. It is therefore impossible to give comparative statistical evidence of the extent to which inclusive education has currently developed in Luxembourg. With regard to employment, the same problems remain as those already identified in the first Action Plan. People with disabilities experience considerable difficulty in finding a job in the mainstream labour market. Unemployment is disproportionately high among people with disabilities and lasts much longer than among job seekers without disabilities. People with disabilities are increasingly oriented towards working in a sheltered workshop under the national guidelines of the Employment Agency. The employment quotas for people with disabilities, which are legally mandated, are largely not met and are not monitored or imposed by the state. Also, some social problems already addressed in the first Action Plan have still not been tackled, such as the legal incapacity of people under guardianship. People with disabilities under guardianship are extensively excluded from self-determination and political participation. They may not vote nor may they run as candidates. As a result, almost 10 years after the introduction of the UN-CRPD no improvement has been made in this area. Furthermore, there are still problems in the implementation of the accessibility of buildings and infrastructure for public use. [less ▲]
