Defining and addressing security and privacy requirements in mobile apps is a significant challenge due to the high level of transparency regarding users' (private) information. In this paper, we propose, apply, and assess a modeling method that supports the specification of security and privacy requirements of mobile apps in a structured and analyzable form. Our motivation is that, in many contexts including mobile app development, use cases are common practice for the elicitation and analysis of functional requirements and should also be adapted for describing security requirements. We integrate and adapt an existing approach for modeling security and privacy requirements in terms of security threats, their mitigations, and their relations to use cases in a misuse case diagram. We introduce new security-related templates, i.e., a mitigation template and a misuse case template for specifying mitigation schemes and misuse case specifications in a structured and analyzable manner. Natural language processing can then be used to automatically detect and report inconsistencies among artifacts and between the templates and specifications. Since our approach supports stakeholders in precisely specifying and checking security threats, threat scenarios and their mitigations, it is expected to help with decision making and compliance with standards for improving security. We successfully applied our approach to industrial mobile apps and report lessons learned and results from structured interviews with engineers. [less ▲]

This paper provides an analysis of two crucial and interconnected aspects of the current legal framework on the investigations conducted by the European Anti-Fraud Office (OLAF): the procedural safeguards for the individuals subject to the administrative investigations conducted by OLAF and the admissibility in evidence of OLAF Final Reports in national criminal proceedings. The state of the art and its shortcomings are analysed in the double perspective of the coherent protection of the EU’s financial interests and of the respect of fundamental rights provided by the EU Charter of Fundamental Rights.

In this paper we describe how to couple reputation systems with distributed consensus protocols to provide high-throughput highly-scalable consensus for large peer-to-peer networks of untrusted validators. We introduce reputation module Guru, which can be laid on top of various consensus protocols such as PBFT or HoneyBadger. It ranks nodes based on the outcomes of consensus rounds run by a small committee, and adaptively selects the committee based on the current reputation. The protocol can also take external reputation ranking as input. Guru can tolerate larger threshold of malicious nodes (up to slightly above 1/2) compared to the 1/3 limit of BFT consensus algorithms. [less ▲]

In Luxembourg, the procedure for identity verification/establishment in the context of international protection is separated from the decision-making procedure as such. While the authority for granting international protection status lies with the Ministry in charge of Immigration (Directorate of Immigration), the Judicial Police is in charge of identity verification/establishment. For this means, the applicant will be interviewed with regard to his/her travel itinerary, including questions on border crossing and used means of transports to arrive in Luxembourg. During the last few years, the large majority of international protection applications in Luxembourg have come from persons originating from the Western Balkan countries (in 2016 they represent 35% of the applicants). Concerning these applicants, most of them (85% to 90%) have presented valid identity documents to the authorities in Luxembourg. However, with the migration crisis there is a growing number of international protection applicants coming from the Middle East and North Africa and who cannot produce valid identity documents. National authorities have always been confronted with lacking identity documents, predominantly observable among applicants from African countries. In some cases, identity documents were intentionally destroyed or withheld from the authorities in order to avoid being identified. If credible identity documents are lacking, the identification procedure can become complicated and resource consuming, and the responsible authorities, especially the Police, have a limited set of methods and means available (provided for in the Asylum Law).

Der vorliegende Forschungsbericht „Der Bachelor in Sozial- und Erziehungswissenschaften (BSSE) und seine Praxisfelder“ beschäftigt sich mit dem Studiengang des BSSE und stellt seine Bedeutung für die luxemburgische Gesellschaft im Allgemeinen und für den Arbeitsmarkt der Sozialen Arbeit im Besonderen dar. Er zeigt die Vernetzung der vielfältigen Praxisfelder und der verschiedenen politischen Bereiche auf. Letztere werden durch Beiträge der jeweiligen Minister von den acht zuständigen Ministerien verdeutlicht. Mit diesem Projekt möchte das PraxisBüro auf die Soziale Arbeit als wesentliche Säule für das Funktionieren unserer Gesellschaft hinweisen und weitere Brücken zwischen den unterschiedlichen Akteuren der verschiedenen Praxisfelder schaffen. Durch den BSSE-Studiengang wird seit über 11 Jahren eine Ausbildung in Sozialarbeit/Sozialpädagogik an der Universität Luxemburg angeboten, die den bestehenden Ausbildungstraditionen aus dem Ausland gegenübertritt. Es ist der einzige Studiengang dieser Art in Luxemburg. Das Diplom ermöglicht die Arbeit als éducateur gradué und/oder assistant social und den Zugang zu der Gehaltsgruppe A2 (Bachelorebene) beim Staat. Die Entwicklung und Bedeutung des Studiengangs wird durch die Anzahl der Absolventen und deren Berufsabschlüsse illustriert, wobei auch die wachsende starke Nachfrage bei den Studienplätzen erstmals systematisch aufgearbeitet wird. Die Argumentation einer Typologie der Praxisfelder gibt den sehr vielfältigen sozialen Bereichen eine Ordnung und ermöglicht somit die Analyse der Praktikumsstellen, der Studienabschlussarbeiten und der beruflichen Praxis der BSSE-Studierenden bzw. BSSE-Absolventen. Der Arbeitsmarkt und die Arbeitsmarktchancen der BSSE-Absolventen werden sowohl durch die existierende Fachliteratur und Informationen der Arbeitsmarktverwaltung als auch durch systematische Arbeitsmarktbeobachtungen (hierbei handelt es sich um ein weiteres Forschungsprojekt des PraxisBüros) untersucht. Die konkreten Praxisfelder werden durch die vorausgegangene Typologie und durch BSSEAbsolventen im Beruf selbst vorgestellt. In diesen Beiträgen finden auch die Absolventen, die sich für ein weiterführendes Master-Studium entschieden haben, ihren Platz. Abschließend unterstreichen Fazit und Ausblick die Bedeutung des Studiengangs für die luxemburgische Gesellschaft und laden zu Kooperations-, Netzwerk- und Weiterbildungsmöglichkeiten ein, die die Brücken zwischen Wissenschaft, Praxis und Politik weiter ausbauen und festigen.

Das Konzept der Bewegten Schule geht auf den Schweizer Pädagogen Urs Illi zurück, der es Mitte der achtziger Jahre vor allem für den Primarbereich entwickelte (Illi, 1995). Ausgehend von einer medizinisch-gesundheitlichen (Bewegung als Gesundheitsressource) und entwick-lungs- und lerntheoretischen (Bewegung als zentrales Element der Kindesentwicklung, Bewe-gung als zusätzlicher Sinnes- und Erfahrungskanal) Begründung, geht es in diesem Konzept grundsätzlich darum, mehr Bewegung in die traditionelle „Sitzschule“ zu bringen. Am Projekt „Bewegter Unterricht in Luxemburg“ nahmen die SchülerInnen und Lehrkräfte der Grundschulen in Angelsberg, Larochette, Nommern, Lintgen und Vichten teil. An den Schulen Angelsberg, Larochette und Nommern fand im Untersuchungszeitraum von September 2014 bis Juni 2016 durchgehend Bewegter Unterricht statt. Diese Schulen werden im Weiteren als „Projektschulen“ bezeichnet. An den Schulen in Lintgen und Vichten wurde nicht „bewegt“ unterrichtet; diese Schulen dienten somit als Kontrollschulen. [less ▲]

As part of the development of the second generation of Eurocodes and harmonization of the different European Codes, some clarifications deal with the design value of concrete compression strength and the bending design of steel-composite sections. The following background document describes the issues in design and confusions between Eurocode 2 for the design of concrete structures and Eurocode 4 for the design of composite structures in steel and concrete. The first part is concentrated on the background information and the accentuation of limits for plastic bending design. While the second part represents the results of multiple comparisons between plastic and strain limited design leading to a new design approach. [less ▲]

In a report published, the Council of Europe anti-corruption body (GRECO) highlights the specificities of Switzerland’s institutions which enjoy considerable public confidence. It underlines, however, that the very organisation of the system allows subtle pressure to be exerted on politicians and the judiciary (See also the French, German and Italian versions of the report). More specifically, GRECO deems it necessary to increase members of parliament’s (MPs) awareness regarding issues of ethics and conflicts of interest. To this end, it recommends adopting a code, announcing publicly MPs’ conflicts of interest as part of the parliamentary procedure and developing the system for declaring relevant interests. These measures need to be accompanied by a reinforced monitoring of MPs’ compliance with their obligations. While recognising the legitimacy of the principle of the election of judges of the federal courts by the Federal Assembly, GRECO calls for improvements to better ensure the quality and objectivity of the recruitment of these judges. It also underlines the importance of severing ties with the political powers after their election, notably by doing away with the practice of judges paying part of their salary to “their” party. Rules of professional ethics applicable to judges also need to be developed and a transparent disciplinary system put in place. The Office of the Attorney General of the Confederation, which enjoys a large degree of independence, also needs to develop rules of professional ethics applicable to its members and to provide greater transparency in disciplinary matters. The implementation of the 12 recommendations addressed to Switzerland will be assessed by GRECO in the second half of 2018 through its compliance procedure. [less ▲]

Illegal employment by third country nationals is a reality in Luxembourg. However, as well as in the case of grey and informal economy, it is rather hard to grasp or quantify to which extent. Nevertheless, the problem is not as significant as the one of the posted workers which is more relevant and worrisome and needs to be situated in the context of a labour market of the Greater Region. In the past, several labour related regularisation measures have been implemented in Luxembourg in order to provide both employers and employees the possibility to regularise situations of illegal employment. The last labour related regularisation measure was implemented in early 2013 in the context of the transposition of the Employers' Sanctions Directive 2009/52 by law of 21 December 2012. During this regularisation, the Directorate of Immigration received 664 applications. These regularisations give a partial indication of the extent of the phenomenon, even though these numbers do not provide a real picture of the problem because the conditions of this regularisation were very strict and in a very short time frame (less than two months) and a certain number of irregular migrants’ workers were not willing to expose themselves by applying and preferred to remain undetected. This regularisation also provided information on the main sectors were the phenomenon is found in order of importance: HORECA, cleaning, crafts, industry and construction. The Ministry of Labour, Employment and Social and Solidary Economy at the end of the regularisation has insisted in the need to increase the number of controls to employers. The law of 21 December 2012 established administrative as well as criminal sanctions for employers who illegally employ irregularly staying third country nationals, particularly in relation to offenses to the Labour Code in aggravating circumstances. This law amended also article 89 of the Immigration Law abrogating the possibility of making labour related regularisations. The Inspectorate of Labour (‘Inspection de Travail et des Mines’, hereafter called ITM), which is in charge of labour inspections and the control of illegal employment of TCNs in Luxembourg, is currently going through a restructuring phase following the latest audit of this administration from January 2015. Particularly the current insufficient number of staff of the ITM, which is in need of a significant short term increase of staff, represents a main challenge in the field of illegal employment in Luxembourg. It is also in the context of this restructuring phase of the responsible administration that the drafting of this study presented a number of challenges, especially in relation to the operational and statistical part of the template. The information regarding the conditions to be fulfilled by both the employers and the employees in the context of an employment relationship are available on the website of the concerned authorities. Furthermore, they are disseminated by the NGOs working in the field, even though there are no specific campaigns targeted to prevent illegal employment of TCNs. The matter was raised in the context of the ‘social identification badge’, which was introduced in 2013 in order to fight against social dumping in particular in the construction sector. One national stakeholder suggested that the ‘social identification badge’ could be revised and adapted to other economic sectors in order to better monitor and prevent illegal employment. In regards to access to justice and enforcement of rights of illegally employed TCNs, Luxembourg foresees the right for illegally employed TCNs to make a claim against their employer, including in cases in which they have, or have been, returned. This claim falls under the general provisions concerning the right to bring a case before civil courts. The Labour Code establishes that the employer who has employed an irregular staying third-country national must pay to the third-country national the following amounts: 1) salaries and any other emoluments, which a similar employee would have benefited for the same employment; 2) the total amount of outstanding remuneration as well as the cost of the transfer of these amounts to the third-country national to the country to which s/he is returned; 3) the total amount of unpaid social contributions and taxes, including administrative fines, as well as, court and legal fees. In addition, the Labour Code establishes that the third-country national who has been illegally employed before the execution of any return decision has to be systematically and objectively informed by the control agents of his/her rights to recover the outstanding remunerations and back payments, as well as the right to benefit from free of charge legal aid in order to attempt a recovery action against the employer, even if the third-country national has already been returned. Labour unions can support and assist TCNs in legal proceedings related to social and labour law, provided that they have been given a mandate to do so. Eventual costs of administrative and civil proceedings can be taken in charge by the labour unions if the TCN is a member of the respective labour union. The Law does not establish fines against TCN’s who were illegally employed. The TCN may be issued a return decision and lose his/her residence rights; however, the Directorate of immigration processes these situations on a case-by-case basis and inform the persons concerned to terminate the illegal employment situation.

In Luxembourg, family reunification is one of the main reasons for immigration of third-country nationals. In fact, “family member” and “private reasons (family links)” residence permits (first deliveries and renewals) represented more than a third of all residence permits issued during the last three years. While the right to family reunification was solely provided by international law and regulated by administrative practice until 2008, the transposition of Directive 2003/86/EC of 22 September 2003 on the right to family reunification led to a much more precise and detailed legal framework. A notable change in legislation has been proposed with the introduction of bill n° 6992 , namely the harmonisation of the conditions that apply to third-country national employees with those of Blue Card holders and researchers. Thus, family reunification requirements for certain categories of applicants shall be alleviated through the abrogation of the 12-month residence requirement for the sponsor. In order to apply for family reunification in Luxembourg, sponsors have to meet a number of requirements for exercising the right to family reunification, which include the provision of suitable accommodation for the size of their family; meeting health and safety standards; health insurance; as well as stable and regular resources to provide for themselves and their family members. As recommended by Directive 2003/86/EC, Luxembourg sets out more favourable conditions to beneficiaries of international protection for the exercise of their right to family reunification. Thus, they do not have to comply with the above-mentioned requirements in case they apply for family reunification within 3 months of being granted the status. Family members who have come to Luxembourg under family reunification have access to education, orientation, vocational training, lifelong learning and professional retraining once their residence permit has been issued. Family members furthermore have access to the labour market. In case the family member has resided in Luxembourg for less than one year when the application is submitted, it will be submitted to the labour market test. Family members can also, under a number of conditions, benefit from guaranteed minimum income, social aid, long-term residence status as well as citizenship. National stakeholders noted that the requirement of finding appropriate accommodation and proving stable and regular resources is one of the main challenges for sponsors. For family members as well as sponsors, having sufficient financial resources to cover the costs of family reunification can be another challenge to accessing family reunification. Family members of beneficiaries of international protection in particular face the more procedural challenge of providing proof of identity and family links, which can be difficult due to lacking documentation, differing administrative practices in the country of origin and/or the lack of cooperation of institutions. Gaining access to family reunification is also particularly difficult for beneficiaries of international protection who arrived in Luxembourg as unaccompanied minors but reached adulthood during the examination of their file, as they must provide proof of their family member’s dependency upon them. The limited number of diplomatic representations of Luxembourg abroad poses a challenge both to family members who must present themselves there, as well as for the Luxembourgish authorities who require information on certain countries. Perceived as a best practice with regard to family reunification are the information that NGOs and the lawyers in the field of migration and asylum provide to beneficiaries of international protection with regard to procedures of family reunification, thereby contributing to the beneficiary’s ability to enter an application for family reunification within the 3-month period. The practice of accepting the submission of an application of family members of beneficiaries of international protection that contains only a commencement of proof of family links and allowing for the finalisation at a later date is also perceived as a good practice, as it enables them to exercise their right to family reunification while benefitting from more favourable conditions. Furthermore, the issuance of a “laisser-passer” for beneficiaries of international protection who cannot obtain travel documents is perceived as a big step forward by national stakeholders. Lastly, Restoring Family Links, a service provided by the Luxembourgish Red Cross, is also considered a reliable tool with regard to tracing missing family members abroad. [less ▲]

The present report provides an overview of the main debates and developments in relation to migration and asylum in Luxembourg in 2016. The issue of migration remained on the forefront of public and political debate, a debate axed on both planned legislative changes as well as the concrete migratory situation in Luxembourg. Four topics dominated public and policy discussions over the course of the year: the reform on Luxembourgish nationality, economic migration, the organisation of reception, as well as support and integration measures, linked to the continued inflow of applicants for international protection (AIPs) in 2016 and steps taken to adapt formal and informal education to the increasing heterogeneity of Luxembourg’s population. The debate on international protection that arose in 2015 was carried onward in 2016, the focus shifting towards reception, support and integration measures. As the inflow of AIPs remained relatively high in 2016 with 2.043 applications, Luxembourg’s Reception and Integration Agency (OLAI) warned throughout the year that the country’s structures would soon reach the limits of their capacity. Linked to the high recognition rate, the legal challenges that local residents put to the plans for the construction of new reception facilities and the difficulty of beneficiaries of international protection (BIPs) in finding appropriate accommodation, the perceived dearth of housing was discussed broadly by the public, the media, as well as civil society and political actors. The continued inflow of AIPs also put a strain on the concerned administrations, both in terms of financial and human resources, leading to discussions regarding the duration of procedures and the variations of this duration. Moreover, the question of integration or support measures for beneficiaries and applicants stepped to the forefront: the changed profile of people arriving in Luxembourg posed new challenges to language learning and education for the newly arrived, and overall, emphasised the need to adapt existing and create new integration and support measures for beneficiaries and applicants. At the same time, the role of non-governmental organisations in supporting the government in the reception of applicants and in establishing new projects facilitating their integration also grew over the course of 2016, not least due to over 80 projects being granted funding by the Oeuvre Nationale de Secours Grande Duchesse Charlotte (henceforth Oeuvre). The Luxembourgish Centre for Integration and Social Cohesion (LISKO), part of the Red Cross and supported by convention to the Ministry for Family and Integration opened its doors in April 2016. The newly created centre will take care of the integration of BIPs into Luxembourg’s society, putting its emphasis on facilitating access to housing. The planned extension of the maximum period of detention for families with children and unaccompanied minors (UAMs) from 72 hours to 7 days precipitated strong reactions from civil society and the public. Luxembourg furthermore followed through on its resettlement and relocation commitments made in 2015, with 167 persons being relocated from Greece and Italy to Luxembourg and with 52 being resettled in the context of the EU-Turkey agreement over the course of 2016. The adaptation of Luxembourg’s legislation in the domain of legal migration also took shape over in 2016 and was broadly debated during the law-making process, while warranting less public attention. With the introduction of one bill, the legislator started the process of transposing Directive 2014/36/EU on seasonal workers and Directive 2014/66/EU on intra-corporate transfers into national law. The same bill furthermore introduced an authorisation of stay for investors, the aspect most commented on by civil society; a mechanism for continuation of activity; detailed the conditions under which a TCN (third country national) corporate officer (mandataire social) can apply for an authorisation of stay, extended the period of validity of the "European Blue Card" residence permit from two to four years, modified dispositions regarding the change of status of students and facilitated family reunification. These developments are to be framed within a wider context of economic diversification, encouragement of entrepreneurship and the repositioning of the financial centre. The reform of the Luxembourgish nationality, another major subject of discussion, was recognised as the best way to counteract Luxembourg’s increasing democratic deficit after the electorate’s refusal to extend legislative voting rights to foreign residents, decided in the referendum of 2015. This reform further proceeded over the course of 2016, reintroduced the perennial language debate in Luxembourg, a larger debate on the role and status of the Luxembourgish language as well as its relation to integration of migrants into Luxembourgish society. In order to increase foreign residents’ participation in the upcoming municipal elections of October 2017, the government launched an awareness campaign encouraging foreign residents to register on the electoral roll, and provided support for organisations wishing to organise complementary actions. The Ministry of National Education and Youth made efforts to find responses to the growing heterogeneity of Luxembourg’s population, aiming to diversify and broaden the post-primary school offer, to develop plurilingual education in nurseries and to develop non-formal education by reforming in-kind benefits, this with the aim of promoting integration and equal opportunity. The transposition of Directive 2013/55/EU on the recognition of professional qualifications was also completed in 2016. The law further amended several national provisions, recast the legislation in the field of recognition of diplomas, combined all applicable provisions in a single legislative text and simplified the procedure for recognition. The debate regarding the return of irregular migrants circled around a number of issues in 2016: the exclusion of Kosovar nationals from the AVRRL programme, the Schengen evaluation and the aforementioned resulting changes to provisions on detention, the debate on the enforcement of the EU-Afghanistan ‘Joint way forward on migration issues’ agreement, as well as the continuation of the elaboration of readmission agreements. Luxembourg’s government took further steps in the fight against trafficking in human beings (THB) over the course of 2016. The Council of Government adopted the National Action Plan on trafficking in human beings, which focuses on the detection and protection of victims, the prosecution and punishment of perpetrators and a policy to combat trafficking. Luxembourg’s strategy on prostitution was presented, consisting of a National Action Plan on prostitution and a bill strengthening the fight against the exploitation of prostitution, procuring and THB. Additionally, the Consultative Commission on Human Rights (Commission Consultative des Droits de l’Homme – CCDH) published its first report on THB, which reviewed the years 2014-2016. In reference to migration and development, Luxembourg continued putting emphasis on vocational training and integration programmes in its indicative cooperation programmes with partner countries. Additionally, the Council of Government approved the bill on the agreement between the Grand Duchy of Luxembourg and the Republic of Cape Verde on the concerted management of migratory flows and solidarity-based development, facilitating the movement of persons and to encourage temporary circular professional migration between Luxembourg and Cape Verde.

Recent extensions of description logics for dealing with different forms of non-monotonic reasoning don’t take us beyond the case of defeasible subsumption. In this paper we enrich the DL EL⊥ with a (constrained version of) a typicality operator •, the intuition of which is to capture the most typical members of a class, providing us with the DL EL•⊥. We argue that EL•⊥ is the smallest step one can take to increase the expressivity beyond the case of defeasible subsumption for DLs, while still retaining all the rationality properties an appropriate notion of defeasible subsumption is required to satisfy, and investigate what an appropriate notion of non-monotonic entailment for EL•⊥ should look like.

Security is an increasingly fundamental requirement in Software-Defined Networking (SDN). However, the pace of adoption of secure mechanisms has been slow, which we estimate to be a consequence of the performance overhead of traditional solutions and of the complexity of the support infrastructure required. As a first step to addressing these problems, we propose a modular secure SDN control plane communications architecture, KISS, with innovative solutions in the context of key distribution and secure channel support. A comparative analysis of the performance impact of essential security primitives guided our selection of basic primitives for KISS. We further propose iDVV, the integrated device verification value, a deterministic but indistinguishable-from-random secret code generation protocol, allowing the local but synchronized generation/verification of keys at both ends of the channel, even on a per-message basis. iDVV is expected to give an important contribution both to the robustness and simplification of the authentication and secure communication problems in SDN. We show that our solution, while offering the same security properties, outperforms reference alternatives, with performance improvements up to 30% over OpenSSL, and improvement in robustness based on a code footprint one order of magnitude smaller. Finally, we also prove and test randomness of the proposed algorithms. [less ▲]

Ce rapport est consacré à une question cruciale pour la Francophonie : le développement démographique, socioéconomique et humain comparé à l’horizon 2050 des sociétés francophones – ces pays membres ou non de l’APF où la langue française joue un rôle important dans l’échange d’idées au quotidien. Il s’agit ici tout à la fois d’un bilan de ce développement depuis 1980 et d’une prospective à l’horizon de 2050. Nous soulignons le renouveau mondial de la francophonie au cours du XXIe siècle, en particulier dans le contexte de sociétés multilingues. Après des décennies de stagnation en proportion de la population mondiale, les pays francophones et la francophonie pourraient émerger comme troisième ère linguistique après l’Anglais et le Chinois, avec une présence sur l’ensemble des continents. Au travers d’un bilan dynamique des sociétés francophones, un ensemble de défis sont mis en évidence : la comparaison met en lumière les risques démographiques, de surpopulation, de pauvreté extrême, de gradient de développement humain (éducation, santé, égalité entre femmes et hommes, etc.). La génération qui vient pourrait voir une amplification des difficultés si nous suivons le scénario central de la prospective. Un autre scénario, optimiste, permet d’envisager une meilleure croissance des pays les plus pauvres, une marche vers l’égalisation du développement humain, un redéveloppement harmonieux, en promouvant la richesse humaine des pays en développement. C’est le message du philosophe Hans Jonas : en nous conformant au devoir d’améliorer le sort des générations suivantes, en investissant en elle, nous nous enrichirons ensemble. Sur cette voie, la pratique d’une francophonie multilingue – où le français est une langue officielle parmi d’autres – semble offrir aux pays qui la connaissent un surcroît de ressources de développement, en accroissant les canaux de la communication en interne et avec les autres pays.

Die vorliegende Arbeit ist Teil des durch das Bundesministerium für Bildung und Forschung geförderten Forschungsprojektes Synchronisierte und energieadaptive Produktionstechnik zur flexiblen Ausrichtung von Industrieprozessen auf eine fluktuierende Energieversorgung (SynErgie). Ziel des Forschungsprojektes ist die Befähigung der energieintensiven Industrien in Deutschland, die Stromnachfrage dem zunehmend fluktuierenden Stromangebot anzupassen. In der Vergangenheit waren Stromsysteme in der Regel dahingehend ausgelegt, dass die Erzeugungsseite des Marktes an das zeitliche Verhalten des Verbrauchs angepasst war. Durch den verstärkten Ausbau volatiler erneuerbarer Energien unterliegt die Stromerzeugung jedoch unkontrollierbaren, wetterabhängigen Schwankungen, weshalb eine Flexibilisierung des Gesamtsystems zunehmend an Bedeutung gewinnt. Die in SynErgie betrachteten Industrieprozesse stellen dabei eine Teilmenge potenzieller Flexibilisierungsoptionen dar und können zur Lastanpassung an schwankende Erzeugung sowie zur Bereitstellung von Systemdienstleistungen und Entlastung der Netze beitragen. In einem liberalisierten, wettbewerblichen Strommarkt sind im Hinblick auf die Erschließung der Potenziale der Nachfrageflexibilität die marktlichen und regulatorischen Rahmenbedingungen von hoher Relevanz. Diese Studie beschreibt daher zunächst die Grundlagen des Strommarktdesigns und des konstituierenden gesetzlichen Rahmens. Dabei wird stets der Bezug zur Anwendung auf Industrieprozesse genommen und potenzielle Hemmnisse der Partizipation flexibler Nachfrageprozesse aufgearbeitet. Die Analyse bildet den Ausgangspunkt für die folgenden Arbeitspakete im Cluster IV und dient der clusterübergreifenden Information über den Status Quo der Marktstrukturen und regulatorischen Rahmenbedingungen. Neben der systematischen Aufarbeitung des marktlichen Rahmens werden die wissenschaftliche Literatur sowie bereits publizierte Studien zum Thema Nachfrageflexibilität (Demand Side Management und Demand Response) in einer Metastudie analysiert und zusammengefasst.

The main objective is to examine the interactions between various sectors in the determination of wages. After a brief description of sectoral specificities in wage setting, the core of the project consists in estimating different wages functions taking into account wage spillovers across macro-sectors (manufacturing industry, finance, other services and public sector). To this end, we use quarterly sectoral data on four countries (Belgium, Luxembourg, France, Germany) over the period 1995-2014 and we estimate VAR-ECM and other econometric models addressing potential endogeneity problems.

Source code terms such as method names and variable types are often different from conceptual words mentioned in a search query. This vocabulary mismatch problem can make code search inefficient. In this paper, we present Code voCABUlary (CoCaBu), an approach to resolving the vocabulary mismatch problem when dealing with free-form code search queries. Our approach leverages common developer questions and the associated expert answers to augment user queries with the relevant, but missing, structural code entities in order to improve the performance of matching relevant code examples within large code repositories. To instantiate this approach, we build GitSearch, a code search engine, on top of GitHub and StackOverflow Q\&A data. We evaluate GitSearch in several dimensions to demonstrate that (1) its code search results are correct with respect to user-accepted answers; (2) the results are qualitatively better than those of existing Internet-scale code search engines; (3) our engine is competitive against web search engines, such as Google, in helping users complete solve programming tasks; and (4) GitSearch provides code examples that are acceptable or interesting to the community as answers for StackOverflow questions.

Digitalization has redefined many aspects of our daily lives and continues to do so. Increasingly, it is also redefining how we perceive and experience mobility and transportation. With this paper, we wish to offer a way of capitalizing on this transformation. It is our shared opinion that, as of today, we will need to build a cooperative new digital mobility infrastructure beyond company borders and across established industries. We thus extend an invitation to contributors from around the globe - companies, scientific and governmental institutions, and commuters - to join us and shape this digital mobility infrastructure together.

Le présent rapport fait la synthèse des principaux débats et des évolutions concernant l’immigration et l’asile au Luxembourg en 2016. Au cours de cette année, quatre sujets ont dominé les discussions publiques et politiques : l’organisation de l’accueil, ainsi que les mesures de soutien et d’intégration, en lien avec l’afflux continu de demandeurs de protection internationale (DPI) en 2016, la réforme de la loi sur la nationalité luxembourgeoise, la migration économique, et les mesures prises ou envisagées pour adapter l’éducation formelle et informelle à l’hétérogénéité croissante de la population luxembourgeoise. Le débat sur la protection internationale soulevé en 2015 s’est poursuivi en 2016, en se concentrant cette fois-ci sur les mesures d’accueil, de soutien et d’intégration. L’afflux de DPI demeurant relativement élevé en 2016 avec 2 043 demandes, l’Office luxembourgeois de l’accueil et de l’intégration (OLAI) n’a cessé, tout au long de l’année, de mettre l’accent sur le fait que les structures du pays atteindraient prochainement les limites de leur capacité d’accueil. Les difficultés que rencontrent les bénéficiaires de protection internationale (BPI) pour trouver un logement approprié et la contestation tant populaire que judiciaire des résidents locaux pour contrer les projets de construction de nouveaux foyers d’accueil, ont donné lieu à des débats à grande échelle auxquels ont participé le public, les médias ainsi que la société civile et les acteurs politiques. L’afflux continu de DPI a également exercé des pressions sur les administrations concernées, aussi bien en termes de ressources financières que de ressources humaines, et ont entraîné des discussions sur la longueur des procédures et les variations de ces délais. L’accueil des DPI et l’intégration des BPI est devenu un défi important alors que le nouveau profil des personnes entrant au Luxembourg a induit de nouveaux enjeux en termes d’apprentissage de la langue et d’éducation des nouveaux arrivants et dans l’ensemble, a souligné la nécessité d’adapter les mesures de soutien existantes et d’en créer de nouvelles pour les bénéficiaires et les demandeurs. Parallèlement, le rôle des organisations non gouvernementales en matière de soutien du Gouvernement dans le cadre de l’accueil des demandeurs et de mise en place de nouveaux projets venant faciliter leur intégration, a également pris de l’ampleur en 2016, notamment du fait des plus de 80 projets financés par l’Œuvre Nationale de Secours Grande Duchesse Charlotte (ci-après l’Œuvre). De nouveaux acteurs sont apparus sur la scène publique avec l’instauration du Centre luxembourgeois pour l’intégration et la cohésion sociale (LISKO) de la Croix Rouge conventionné par le ministère de la Famille, de l’Intégration et à la Grande Région, qui a pour objet de promouvoir l’intégration des BPI au sein de la société luxembourgeoise, en privilégiant l’accès au logement. Toujours, sur le plan de la protection internationale, le Luxembourg a poursuivi les engagements pris en 2015 en matière de réinstallation et de relocalisation, 167 personnes ayant été relocalisées de Grèce et d’Italie vers le Luxembourg et 52 ayant été réinstallées dans le cadre de la Déclaration UE-Turquie en 2016. La lutte contre la traite des êtres humains (TEH) était un autre sujet de préoccupation important en 2016. Le Conseil de gouvernement a adopté le Plan d’action national sur la traite des êtres humains qui comprend des mesures relatives à la détection et la protection des victimes, la poursuite judiciaire et les sanctions imposées aux auteurs et qui vise la mise en place d’une politique active et efficace de lutte contre la traite. La stratégie du Luxembourg sur la prostitution a été présentée : elle consiste en un Plan d’action national sur la prostitution et en un projet de loi qui renforce la lutte contre l’exploitation de la prostitution, le proxénétisme et la traite des êtres humains. De plus, le rapporteur national, la Commission Consultative des Droits de l’Homme (CCDH) a publié son premier rapport sur la traite des êtres humains, qui couvre les années 2014 à 2016. L’adaptation de la législation luxembourgeoise dans le domaine de la migration légale a également pris forme en 2016, bien que suscitant moins d’intérêt et de débat public. Avec l’introduction d’un projet de loi, le législateur a lancé le processus de transposition de la Directive 2014/36/UE sur les travailleurs saisonniers et de la Directive 2014/66/UE sur les transferts temporaires intra-groupe en droit national. Ce même projet de loi a également introduit une autorisation de séjour destinée aux investisseurs et un mécanisme de continuité d’activité, a détaillé les conditions dans lesquelles un mandataire social ressortissant d’un pays tiers (RPT) pouvait demander une autorisation de séjour, a prolongé la période de validité du titre de séjour « Carte bleue européenne », a modifié les dispositions concernant le changement du statut des étudiants et a facilité le regroupement familial. Ces évolutions sont à situer dans un contexte plus large de diversification économique, d’incitation à l’entreprenariat et de repositionnement du centre financier. Dans le domaine de la migration et du développement, le Luxembourg a continué de mettre l’accent sur les formations professionnelles et les projets d’intégration dans ses programmes indicatifs de coopération avec les pays partenaires. Par ailleurs, le Conseil de gouvernement a approuvé le projet de loi sur l’accord entre le Grand-Duché de Luxembourg et la République du Cap-Vert sur la gestion concertée des flux migratoires et le développement solidaire facilitant la circulation des personnes et visant à encourager la migration professionnelle circulaire temporaire entre le Luxembourg et le CapVert. Sur le plan du retour des migrants en situation irrégulière ou sans droit de séjour il convient de mentionner l’exclusion des ressortissants du Kosovo du programme AVRRL, le processus d’évaluation Schengen et les changements qui en résultent sur les dispositions en matière de rétention : L’extension prévue de la période maximale de rétention pour les familles avec enfants et pour les mineurs non accompagnés (MNA) qui devait passer de 72 heures à 7 jours, a suscité de vives réactions de la part de la société civile. La mise en œuvre de la Déclaration UE-Afghanistan « Joint Way Forward on migration issues », ainsi que la poursuite de l’élaboration des accords de réadmission ont constitué d’autres aspects importants de la politique migratoire. Sur le plan des politiques d’intégration, le projet de réforme de la loi sur la nationalité luxembourgeoise a été considéré comme moyen important pour lutter contre le déficit démocratique croissant du Luxembourg suite au refus des électeurs d’accorder le droit de vote aux résidents étrangers pour les législatives lors du référendum de 2015. Avec ce projet de réforme a été relancé le perpétuel débat sur les langues au Luxembourg, en particulier sur le rôle et le statut de la langue luxembourgeoise et son lien avec l’intégration des migrants au sein de la société luxembourgeoise. Afin de renforcer la participation des résidents étrangers aux prochaines élections municipales du mois d’octobre 2017, le Gouvernement a lancé une campagne de sensibilisation, pour encourager les résidents étrangers à s’inscrire sur les listes électorales. Le ministère de l’Education nationale, de l’Enfance et de la Jeunesse s’est efforcé de trouver des réponses à l’hétérogénéité croissante de la population luxembourgeoise, en visant à diversifier et à élargir l’offre d’enseignement, à développer l’éducation non formelle et l’éducation plurilingue dans les crèches dans le but de promouvoir l’intégration et l’égalité des chances. La transposition de la Directive 2013/55/UE sur la reconnaissance des qualifications professionnelles a également été menée à bien en 2016. La loi a modifié plusieurs dispositions nationales, et regroupé toutes les dispositions applicables en un seul texte législatif tout en simplifiant la procédure de reconnaissance. [less ▲]

Im vorliegenden Bericht werden die aktuellen Befunde der Evaluation der Schulung BEE SECURE aus dem Jahr 2016/17 dargestellt. Die Schulung zur Förderung der Medienkompetenz wurde in diesem Jahr an 144 Grund- und Sekundarschulen in Luxemburg durchgeführt. Im Anschluss an die Schulung wurden jeweils von den Trainern, die die Schulung gehalten hatten und von den Schülern und deren Lehrern Fragebögen ausgefüllt. Somit lagen die Daten von 739 Trainerfragebögen, 768 Lehrerfragebögen und 10062 Schülerfragebögen dem Evaluationsdatensatz zugrunde. Der Lehrerfragebogen beinhaltete verschiedene Aussagen zur Effektivität der Schulung und zur Durchführung der Schulung. Es zeigte sich, dass die Lehrer sowohl mit der Effektivität als auch der Durchführung zufrieden bis sehr zufrieden waren. Die Auswertung der Trainerfragebögen zeigte, dass sie mit den meisten Aspekten des Trainings zufrieden waren. Besonders positiv wurden die Disziplin, das Klassenklima, die Lehrkräfteeinbindung sowie die Organisation bewertet. Weniger positiv wurde der Wissenstand der Schüler im Bezug auf das Internet und die Erfahrungsberichte der Schüler wahrgenommen. In Bezug auf die Schülerdaten zeigte sich, dass knapp über die Hälfte der Schüler bereits schon mal an einer BEE SECURE Schulung teilgenommen hatten. Alle abgefragten Aspekte des Trainings wurden von den Schülern durchweg als sehr positiv eingeschätzt. [less ▲]

Applications for international protection significantly increased in Luxembourg from August 2015 onwards, the total number of applications in fact more than doubling when compared to the previous year (2.447 applicants in 2015; 1.091 in 2014). The number of applications remained high in 2016 (2.035 applications) and 2017 (2.322 applications) albeit slightly decreasing when compared to 2015. These figures are not unprecedented. The number of applications introduced in Luxembourg have fluctuated since 1999, the peaks and declines correlating with specific events. Luxembourg received 2.920 applications for international protection in 1999, an effect of the conflict in Kosovo. Later, the country saw two more peaks in applications after the turn of the century (2003 and 2004 with 1.550 and 1.577 applications respectively, 2011 and 2012 with 2.171 and 2.057 applications respectively). On the other hand, 2005 to 2010 can be characterised as a period of relative calm.The current period of higher arrivals of applicants for international protection is characterised by a change in cultural profile. Previously, most of the time, a majority of people applying for international protection in Luxembourg stemmed from European countries. The influx of applicants in 2015 and 2016 was characterised by the arrival of people stemming from Arabic-speaking countries, populations which had been relatively small in Luxembourg up to that point.While not necessarily unprecedented in magnitude,high numbers of monthly arrivals, especially in the last months of 2015, put those in charge of registering applications as well as of housing and providing social follow-up to the test and led to a number of measures being taken.Generally speaking, fromthe beginning of the increased arrivals in Luxembourg in 2015, the government adopted a relatively open and welcoming position. This position is illustrated for instance in the government’s stance in favour of a solution for the reception of applicants for international protection that is based on European solidarity and the government’s investment in relocation and resettlement.

In response to the tender specifications the study consists of two parts. The first examines whether divergences in national procedural laws and practices constitute obstacles to mutual trust and, in the affirmative, identifies the locus and the scale of such obstacles; it thereby facilitates the identification of the areas in which mutual trust needs to be further enhanced in line with the European Council Conclusions of 26/27 June 2014. In addition, the study addresses possible obstacles to legal certainty when businesses and citizens engage in cross-border litigation. The second strand of the study evaluates whether and to what extent national procedural laws and practices ensure the effective procedural protection of EU consumers. Both strands of the study investigate the legal and the practical situations in the civil procedural laws of the 28 EU Member States. [less ▲]

The study of human mobility and activities has opened up to an incredible number of studies in the past, most of which included the use of sensors distributed on the body of the subject. More recently, the use of smart devices has been particularly relevant because they are already everywhere and they come with accurate miniaturized sensors. Whether it is smartphones, smartwatches or smartglasses, each device can be used to describe complementary information such as emotions, precise movements, or environmental conditions. In this short paper, we release the applications we have developed and an example of a collected dataset. We propose that opening multi-sensors data from daily activities may enable new approaches to studying human behavior. [less ▲]

Die vorliegende Studie zur Situation der Jugendlichen in der Gemeinde Strassen wurde von der Forschergruppe „youth research“ an der Forschungseinheit INSIDE (Integrative Research Unit on Social and Individual Development) der Universität Luxemburg im Auftrag des Bürgermeister- und Schöffenrates der Gemeinde Strassen erstellt. Diese Studie ist Teil des Jugendkommunalplans für die Gemeinde Strassen und hat zum Ziel, den Verantwortlichen in Politik, Verwaltung und Jugendarbeit Informationen zu liefern, die zu einem besseren Verständnis der Jugendlichen in der Gemeinde beitragen. Denn die Gruppe der Jugendlichen repräsentiert mit ihren Wünschen, eigenen Sichtweisen und Erwartungen eine zentrale Entwicklungsperspektive für die Gemeinde Strassen. Unter anderem aus diesem Grund sind die Ergebnisse dieser Studie eine wichtige Informations- und Diskussionsgrundlage für die zukünftige Planung und Umsetzung der kommunalen Jugendpolitik und ein wichtiges Fundament für „Evidence-based-policy-making“, also eine wissensbasierte Jugendpolitik in Strassen. Diesem Anliegen entsprechend wurde diese Studie als Situations- und Bedarfsanalyse konzipiert. Wichtige thematische Aspekte sind insbesondere die Lebenswelten, das Freizeitverhalten und die Freizeitinteressen der Jugendlichen in Straßen aber auch die sozialen Herkunftsmilieus die einen starken Einfluss auf die Startbedingungen, Lebensentwürfe und Zukunftsperspektiven der Jugendlichen haben. Nicht zuletzt interessiert auch die Frage, wie die Jugendlichen unterschiedlicher Herkunft in der Gemeinde integriert sind, wie zufrieden sie mit den Angeboten und der Infrastruktur sind, welche Möglichkeiten der Partizipation für sie wichtig sind und inwiefern die Maßnahmen und Angebote der kommunalen Politik die Jugendlichen erreichen. In diesem Zusammenhang ist auch ein genauerer Blick auf die Situation der Jugendlichen mit einer ausländischen Nationalität von Interesse, zum Beispiel die Frage, wo Defizite aber auch Chancen einer stärkeren Integration oder Beteiligung dieser großen Zahl an Jugendlichen am Gemeindeleben bestehen. Bei vielen Themenbereichen sind Vergleiche mit anderen luxemburgischen oder mit internationalen Jugendstudien möglich. Dadurch können Gemeinsamkeiten sowie Besonderheiten der Gemeinde Straßen deutlich gemacht werden. [less ▲]

Addressing these challenges is paramount, as it is well-trained health care professionals who will build the strong PHC systems that are necessary for UHC. Due to the continuing spread and evolution of information and communications technology (ICT) in health care and education, ICT should be considered as an essential tool for innovative primary health care education.  Many nations face a distinct lack of UHC, grossly unequal health services and an acute shortage of suitably qualified family doctors, nurses and allied health care professionals that constitute the primary health care team. It is estimated that by 2035, the world will have a shortage of 12.9 million health care professionals, however an additional 1.9 billion people will require health care. Recruiting, educating and retaining these primary health care teams is therefore fundamental to meet ongoing demands.  Family doctors contribute to high quality, cost-effective and accessible primary health care. However, PHC faces considerable challenges, including a preference from policymakers, the public, and members of the health care community for specialisation. Specialist-focused care may be attractive, but it is often economically unsustainable and absorbs resources that are necessary for PHC. Yet, cooperation between primary and secondary care is essential for delivering the best care to patients and communities. It should not be a matter of choosing between primary and secondary care, but rather of recognising and adequately supporting the unique attributes and skillsets that each has to offer.  Family medicine lies at the heart of primary health care. The key to producing skilled family doctors is good family medicine training, particularly at a postgraduate level. There is great potential to improve the scale and quality of family medicine training, starting with exposure to the field as early as possible. For the delivery of primary care to be effective – and lead to the achievement of universal health coverage – the composition of the primary care team should reflect the demography and health needs of the local population. Thus, the composition of the primary care team will differ from location to location, depending on the age/sex/ health needs of the local population. Family doctors and all of the PHC professionals should have a set of universal core skills, in addition to skills specific to the population and geography they serve. To provide effective care, health professionals need to understand the importance of social factors in influencing population health; therefore, training curricula must be adapted to local contexts  Career development through postgraduate training strongly motivates health professionals to stay in their own localities, as well as being vital for patient safety and improved outcomes. Yet, despite a thirst for postgraduate training among family doctors and other primary health care professionals, it is often difficult to access. ICT may be used to address recruitment and retention issues by providing easily accessible and good quality education.  This report examines a key question: Can ICT facilitate the education of PHC professionals worldwide in order to address the challenges facing PHC and UHC? Through in-depth literature reviews, analysis, and targeted interviews with key experts, the report concludes that ICT can indeed support, enhance and accelerate the education of the primary health care team’s members, in six key ways:  1. It is an effective means of developing workforce capacity. By overcoming geographical barriers and supplementing traditional instruction with online delivery from international and regional tutors, ICT can substantially increase health care professionals’ access to postgraduate education without the need for travel, thus helping to avoid disruption to healthcare delivery.  2. It helps to recruit and retain professionals. E-learning overcomes issues of access and isolation, and can be done flexibly to suit the learner. By providing access to specialist support, postgraduate courses and mentoring opportunities, e-learning and telehealth encourage in-country and rural retention of health care workers.  3. It is cost-saving. Traditional models of health professional education are expensive, both for the provider and for health care professionals. Developing ICT solutions may entail high initial costs but these are reduced over time, and with more users, achieve economies of scale.  4. It facilitates social and collaborative learning which has been shown to have the greatest impact on patient outcomes. A blend of synchronous and asynchronous e-learning is likely to be the most effective way of achieving interprofessional learning. Communities of practice are encouraged using ICT and social media, reducing professional isolation and improving collaboration.  5. It can help to bring contextualised care to where it is needed. For example, simulation-based medical education enables problem-based, interactive and contextualised learning. End-user (including patient) participation is paramount when designing ICT-based educational programmes.  6. It improves the quality of care by facilitating access to evidence-based medicine and reflective learning. Email alerts can support education by reaching a large audience and providing trustworthy information tailored to individual needs; social media can aid in streamlining vast amounts of information into a small number of tailored-to-the-individual articles; blogs and electronic portfolios can encourage reflective life-long learning. Capturing these opportunities will require stakeholders to consider the following:  a) Securing political and financial support to establish and maintain strong PHC systems  b) Adopting a collaborative interprofessional approach between health professionals, from medical school through to the workplace  c) Providing education and training relevant to the context and to user needs  d) Improving recruitment and retention through training  e) Encouraging the standardisation and accreditation of health professional education  f) Investing in ICT training for learners, educators and patients  g) Planning and developing programmes that use technology meaningfully to improve care quality, cost-effectiveness, accessibility, equity and patient safety  h) Recognise and consolidate the interdependence of all the health professionals in the PHC setting.  [less ▲]

Luxembourg has a long tradition in “resettling” refugees from various parts of the world, but a more structured policy has only recently been implemented. National legislation does not include any provisions relating to resettlement policy and there are no specific national programmes. The resettlements have always been implemented on an ad-hoc basis or within broader programmes set up by the European Commission and/or UNHCR. Since 2014, Luxembourg additionally applies a quota of refugees to be annually resettled (15-20 persons). The implementation and organisation of the resettlement process may vary case by case and there is no standardised procedure applicable except for regular resettlements for which the framework is to a large extent outlined in the UNHCR’s Resettlement Handbook. The selection and identification of resettled persons is coordinated by the Directorate of Immigration in close collaboration with UNHCR, who performs in principle an eligibility assessment for the refugee status, which the Luxembourgish authorities shall take over once the person arrives in Luxembourg. For each resettlement mission Luxembourg sets a general profile as well as the number of persons they intend to resettle. These criteria do basically not differ from UNHCR’s Global Resettlement Submission Criteria and thus include women, children, elderly refugees as well as refugees with disabilities and diseases, except for those suffering from pathologies for which there is no adequate treatment available in Luxembourg. Apart from the vulnerability criteria, Luxembourgish authorities also take the “integration potential” into consideration when selecting candidates eligible for resettlements. This might explain the general preference of resettling entire families rather than single persons. Resettlement implemented within the EU Turkey 1:1 scheme, based on the agreement between the EU and Turkey of 18 March 2016, is considered separately by national authorities. For UNHCR, who is not a party to this agreement, engagement in the resettlement of Syrian refugees from Turkey is considered part of its regular resettlement activities. Procedurally, UNHCR continues to receive resettlement referrals from Turkey’s Directorate General for Migration Management (DGMM) and further continues to undertake phone and face-to-face interviews with eligible candidates. However, as opposed to regular resettlement, the assessment undertaken by UNHCR is streamlined. The Luxembourgish Reception and Integration Agency (OLAI) coordinates the reception and integration phase of the resettled refugees. Although policy and law are the same for both, resettled refugees and other beneficiaries of international protection, in practice the support provided may differ in an initial phase. Thus, resettled refugees are accommodated upon arrival within a common reception centre where they shall be provided with a more intense support, especially during the first weeks after their arrival in Luxembourg. Since April 2016, a newly created service of the Luxembourgish Red Cross (Lisko) has been mandated, under the overall coordination of the Ministry of Family, Integration and the Greater Region, to take charge of the social support and integration of benefeciciaries of international protection, including resettled persons. Other national NGOs and associations also provide counselling and assistance. The present report identifies several challenges faced by both, the resettled persons as well as the competent authorities. These challenges prove particular significant in the post-arrival and integration phase. While some of these challenges are common to beneficiaries of international protection in general, some others may be more specifically relevant for resettled refugees, namely the absence of a transition period, coordination with local stakeholders, as well as timely provision of information to selected candidates for resettlement.

A goal of the project was done to develop a new good-looking racing rim of a sports car which would be lighter than existing ones. To achieve the goal, lightweight magnesium alloy Mg ZK60-T5 was applied for the rim, and its preliminary shape was developed employing topology op-timisation. The rim was designed for forging technology; this means that it had to have all manu-facturing features required by that production process. Based on a literature review, loads, boundary conditions and structural requirements were established, which are crucial for a further development process. The initial design was created using the topology optimisation, and then a parametric model was developed using a CAD system. As a next step, the first part of validation was done employing FEA in order to meet strength and stiffness targets; some modifications of the CAD model were imposed. As the last step, the final validation was done employing simply fatigue assessment. The optimisation and FEA were completed using Hyperworks 14/ Inspire 2015 software and the CAD model employing Autodesk Inventor 2015. The results show that the rim design meets theoretically all structural requirements and a good-looking shape was reached. The total mass of 7.9 kg of the designed rim is obtained, which means a reduction about 1.8 kg with the comparison with a reference rim. The 3D model and a technical drawing are completed; this means that the rim can be sent to a production phase. The results of the project also show that the topology optimisation technology provided by Hyperworks and the advanced CAD system can be used to generate competitive designs with any design offices without difficulties.

The definition and organisation of programs related to their courses of educational institutions is a very complex and exhaustive task. There is a demand for such a solution by the educational institutions, as they need a detailed program descriptions for students and instructors. This task gets even more complicated if these programs and courses needs to be certified according to some international learning standards. At the moment, the availability of such methods or tools is very limited, except for some ad-hoc guidelines, which are use by some few universities, e.g. the Cornell University. Most of the institutions (e.g. University of Luxembourg) allows the professor to us their own methods for specifying their courses. Hence, most of the institutions are sharing similar problems, but using their own defined methods (e.g. naming conventions for its programs). At an university, professors are working in various domains and using therefore their own methods for specifying their courses, which results often in an incomplete program and course description. Methods such as SWEBOK (Software Engineering Body of Knowledge) and CS2103 (Computer Science Curricula 2013) which are program certifications according to an international learning standard are almost not known and used. Thus, programs and courses from different institution cannot be compared, since there is no common structure and process for specifying them. In this master thesis, we present TESMA (Tool for Educational Specification Management and Assessment of teaching programs), a tool based on a domain-specific language, which is dedicated to the teaching domain, for specifying, managing, and assessing programs. The Messir (Scientific Approach to Requirements Engineering) development method has been used for defining the concept and the requirements of the tool. Our research concentrates on the domain-specific language (DSL) in order to define requirements and improving the quality of the DSL’s. We focus on the development of an intuitive and maintainable domain-specific language, usable by people coming from different domains, e.g. software engineers, natural sciences, social sciences, linguistic, and so on. This thesis describes the requirements, the concepts, the realisation, and implementation of the tool, which are based on a domainspecific language of high quality for specifying programs. The quality of our DSL is assessed by a complete used cases related to the University of Luxembourg. [less ▲]

The issue of non-return of rejected international protection applicants does not enjoy a high political profile on its own, but has been discussed as part of a global debate on asylum. Significant efforts are required when considering the wide spectrum of possible reasons of non-return, some reasons depending on the countries of destination, others on the returnee himself/herself. In this respect, reasons of non return range from the non-respect of deadlines, the issuance of travel documents, postponement of removal for external reasons to the returnee, for medical reasons, the resistance of the third-country national and the lack of diplomatic representation of Luxembourg, to name but a few. In regards to the procedure, in Luxembourg the rejection of the international protection application includes the return decision. The Minister in charge of Immigration, through the Directorate of Immigration, issues this decision. The return decision only becomes enforceable when all appeals are exhausted and the final negative decision of rejection of the competent judicial authority enters into force, as appeals have suspensive effects. This decision also sets out the timeframe during which the rejected international protection applicant has to leave the country. In case the applicant does not opt for a voluntary return, the decision will also include the country to which s/he will be sent. In general, the decision provides for a period of 30 days during which the applicant has the option to leave voluntarily and to benefit from financial support in case of assisted voluntary return through the International Organization for Migration (IOM). There are two exceptions to this rule: the applicant who is considered a threat to national security, public safety or homeland security and the applicant who has already been issued a return decision before. The declaration and documentation provided during the procedure of international protection can be used to facilitate return. Subsequent applications are possible, in particular if new evidence of facts appears resulting in an increased likelihood of the applicant to qualify for international protection. For rejected international protection applicants who did not opt for voluntary return and did not receive any postponement of removals, a certain (limited) support is available while waiting for the execution of the enforceable return decision. As such, they continue to stay in reception facilities and to receive certain social benefits unless they transgress any internal rules. If an urgent need exists, rejected applicants may be granted a humanitarian social aid. However, they are not entitled to access the labour market or to receive ‘pocket money’ or the free use of transport facilities. They benefit from an access to education and training, however this access cannot constitute a possible reason for non-return. These benefits are available to rejected applicants until the moment of their removal. In order to enforce the return decision and prevent absconding, the Minister may place the rejected international applicant in the detention centre, especially if s/he is deemed to be obstructing their own return. Other possible measures include house arrest, regular reporting surrendering her/his passport or depositing a financial guarantee of 5000€. Most of these alternatives to detention were introduced with the Law of 18 December 2015 which entered into force on 1st January 2016. As a consequence, detention remains the main measure used to enforce return decisions. A number of challenges to return and measures to curb them are detailed in this study. A part of these measures have been set up to minimize the resistance to return from the returnee. First and foremost is the advocacy of the AVRR programme and the dissemination of information relating to this programme but also the establishment of a specific return programme to West Balkan countries not subject to visa requirements. Other measures aim at facilitating the execution of forced returns, such as police escorts or the placement in the detention centre. Finally, significant efforts are directed towards increasing bilateral cooperation and a constant commitment to the conclusion of readmission agreements. No special measures were introduced after 2014 in response to the exceptional flows of international protection applicants arriving in the EU. While the Return service within the Directorate of Immigration has continued to expand its participation to European Networks and in various transnational projects in matters of return, this participation was already set into motion prior to the exceptional flows of 2014. As for effective measures curbing challenges to return, this study brings to light the AVRR programme but especially the separate return programme for returnees from West Balkan countries exempt of visa requirements. The dissemination of information on voluntary return is also considered an effective policy measure, the information being made available from the very start of the international protection application. Among the cases where return is not immediately possible, a considerable distinction has to be made in regards to the reasons for the non-return. Indeed, in cases where the delay is due to the medical condition of the returnee or to material and technical reasons that are external to the returnee, a postponement of removal will be granted. This postponement allows for the rejected applicant to remain on the territory on a temporary basis, without being authorized to reside and may be accompanied by a measure of house arrest or other. In cases of postponement for medical reasons and of subsequent renewals bringing the total length of postponement over two years, the rejected applicant may apply for a residence permit for private reasons based on humanitarian grounds of exceptional seriousness. Nevertheless, apart from this exception, no official status is granted to individuals who cannot immediately be returned. Several measures of support are available to beneficiaries of postponement to removal: they have access to accommodation in the reception centres they were housed in during their procedure, they may be attributed humanitarian aid, they continue to be affiliated at the National Health Fund, they continue to have access to education and professional training and they are allowed to work through a temporary work authorization. The temporary work authorization is only valid for a single profession and a single employer for the duration of the postponement to removal, although this is an extremely rare occurrence in practice. OLAI may allocate a humanitarian aid might be allocated if the individual was already assisted by OLAI during the procedure of her/his international protection application. All of these measures apply until the moment of return. The study also puts forth a number of best practices such as the Croix-Rouge’s involvement in police trainings, their offer of punctual support to vulnerable people through international networking or the socio-psychological support given to vulnerable people placed in the detention centre among others. A special regard has to be given to AVRR programmes and their pre-departure information and counselling, the dissemination of information and the post-arrival support and reintegration assistance. Indeed, stakeholders singled the AVRR programme out as a best practice and the Luxembourgish government has made voluntary return a policy priority for a long time. However, this increased interest in voluntary returns has to be put into perspective as research shows that sustainable success of voluntary return and reintegration measures is only achieved for a very restricted number of beneficiaries (namely for young, autonomous and dynamic returnees with sizeable social networks and who were granted substantial social capital upon return). Hence, returning women remains a sensitive issue, especially if they were fleeing abusive relationships. Another factor contributing to hardship set forth by research is the difficult reintegration of returnees that have lived outside of their country of return for a prolonged period of time and are therefore unable to rely on social networks for support or for a sense of belonging. Based on these considerations, NGOs and academia cast doubts on the ‘voluntary’ nature of these return programmes, their criticism targeting the misleading labelling of these policy measures.

The biggest problem for a shallow foundation, just as any other type of foundation, is a failure due to an overestimation of the bearing capacity. This means that the correct prediction of the bearing capacity of the foundation is often the most important part of the design of a civil structure. That is why the publication of Prandtl in 1920 about the hardness of a plastic body, was a major step in solving the bearing capacity of shallow foundations, although it is well possible that he never realised this, because his solution was not made for civil engineering purposes, but for mechanical purposes. Over the last 100 year, a lot of extensions have been made, for example with inclination factors and shape factors, and many laboratory experiments have been done and also many numerical calculations have been made. Some even try to extrapolate the failure mechanism for shallow foundations to the failure mechanism around the tip of a pile. All this scientific work leads back to the first publication made by Ludwig Prandtl in 1920. This intermediuate report “100 Year Prandtl’s wedge” has been made for all those who are interested in these fundamentals of foundation engineering and their history. [less ▲]

This technical report details our a semi-automated framework for the reverse-engineering and testing of access control (AC) policies for web-based applications. In practice, AC specifications are often missing or poorly documented, leading to AC vulnerabilities. Our goal is to learn and recover AC policies from implementation, and assess them to find AC issues. Built on top of a suite of security tools, our framework automatically explores a system under test, mines domain input specifications from access request logs, and then, generates and executes more access requests using combinatorial test generation. We apply machine learning on the obtained data to characterise relevant attributes that influence access control to learn policies. Finally, the inferred policies are used for detecting AC issues, being vulnerabilities or implementation errors. We have evaluated our framework on three open-source applications with respect to correctness and completeness. The results are very promising in terms of the quality of inferred policies, more than 94% of them are correct with respect to implemented AC mechanisms. The remaining incorrect policies are mainly due to our unrefined permission classification. Moreover, a careful analysis of these policies has revealed 92 vulnerabilities, many of them are new.

Context: Static analysis approaches have been proposed to assess the security of Android apps, by searching for known vulnerabilities or actual malicious code. The literature thus has proposed a large body of works, each of which attempts to tackle one or more of the several challenges that program analyzers face when dealing with Android apps. Objective: We aim to provide a clear view of the state-of-the-art works that statically analyze Android apps, from which we highlight the trends of static analysis approaches, pinpoint where the focus has been put and enumerate the key aspects where future researches are still needed. Method: We have performed a systematic literature review which involves studying around 90 research papers published in software engineering, programming languages and security venues. This review is performed mainly in five dimensions: problems targeted by the approach, fundamental techniques used by authors, static analysis sensitivities considered, android characteristics taken into account and the scale of evaluation performed. Results: Our in-depth examination have led to several key findings: 1) Static analysis is largely performed to uncover security and privacy issues; 2) The Soot framework and the Jimple intermediate representation are the most adopted basic support tool and format, respectively; 3) Taint analysis remains the most applied technique in research approaches; 4) Most approaches support several analysis sensitivities, but very few approaches consider path-sensitivity; 5) There is no single work that has been proposed to tackle all challenges of static analysis that are related to Android programming; and 6) Only a small portion of state-of-the-art works have made their artifacts publicly available. Conclusion: The research community is still facing a number of challenges for building approaches that are aware altogether of implicit-Flows, dynamic code loading features, reflective calls, native code and multi-threading, in order to implement sound and highly precise static analyzers.

Der Survey zu dem „Quality of Work Index Luxembourg“ (QoW), der von der Universität Luxemburg und der luxemburgischen Chambre des Salariés entwickelt wurde (Steffgen, Kohl, 2013; Sischka, Steffgen, 2015), wurde 2015 bereits zum dritten Mal in einer telefonischen Befragung erhoben. Ziel des Index ist es, die erlebte Arbeitssituation und -qualität luxemburgischer Arbeitnehmer zu erfassen. Der vorliegende Bericht dokumentiert die psychometrische Testung der Güte des aktuellen Erhebungsinstru-ments. In einem ersten Schritt erfolgt die Beschreibung der Verteilung der für die Skalen genutzten Items (Mittelwert, SD, Schiefe, Kurtosis). Im nächsten Schritt erfolgt die Überprüfung der internen Konsistenz der Skalen mittels verschiedener Reliabilitätsstatistiken (Cronbach’s Alpha, Korrelationsanalysen der Items) sowie Koeffizienten zur Beschreibung der Skalenverteilung. Wo vorhanden werden Indikatoren eingesetzt, um die Validität der Konstrukte zu eruieren. Explorative und konfirmatorische Faktoren-analysen dienen dazu, zu testen, ob die Items auf den a priori festgelegten Faktoren laden und ob sich die unterstellte Faktorenstruktur auch in den Daten zeigt. Außerdem werden die Zusammenhänge der Skalen mittels Korrelationsanalysen überprüft. Die QoW-Skalen werden außerdem auf verschiedene Well-Being-Skalen regressiert, um deren Relevanz für den QoW-Index zu überprüfen. Da die Befragung 2015 teilweise als Panelbefragung durchgeführt wurde (Panelbefragte n = 762), wird außerdem überprüft, ob es hinsichtlich demographischer Eigenschaften der Befragten, hinsichtlich der QoW-Skalen oder hinsichtlich verschiedener Well-Being-Maße zu systematischen Ausfällen gekom-men ist. Ebenso werden einige Längsschnitt-Regressionsanalysen gerechnet, um zu überprüfen, ob einige Arbeitsbedingungen längerfristige Effekte auf das Well-Being der Arbeitnehmer in Luxemburg haben. Abschließend wird das gesamte Erhebungsinstrument zusammenfassend diskutiert und Empfehlungen bezüglich der Skalen, der Erhebung demographischer Variablen sowie des Designs der weiteren Befra-gungen gegeben.

Renforcer la cohésion sociale et le vivre ensemble dans notre société, tout en favorisant les mixités des jeunesses au sein des camps et des colos, et en contribuant à l’innovation de ces institutions qui connaissent une désaffection chronique, un triple objectif du dispositif #GenerationCampColo que ce rapport d’évaluation cherche à interroger. Outre des pistes d’innovation, la recherche évaluative interroge les manières de mixer les jeunesses et met en lumière les processus de séparation des publics, en amont, qui entravent les processus de mixité. Ces séparations découlent des politiques publiques sectorielles et du mode de fonctionnement des camps et des colos. Comment passer alors d’une situation de séparation des jeunes, en publics hiérarchisés, à une égalité de traitement dans l’organisation des séjours ? Les résultats montrent la nécessité de construire des séjours « inclusifs » basés sur un accès inconditionnel et un accueil universel. Ces préalables permettront de questionner et discuter, autour d'un « faire ensemble » commun, les socialisations différenciées et les représentations hiérarchisées. [less ▲]

A role-based access control (RBAC) policy restricts a user to perform operations based on her role within an organization. Several RBAC models have been proposed to represent different types of RBAC policies. However, the expressiveness of these models has not been matched by specification languages for RBAC policies. Indeed, existing policy specification languages do not support all the types of RBAC policies defined in the literature. In this paper we aim to bridge the gap between highly-expressive RBAC models and policy specification languages, by presenting GemRBAC-DSL, a new specification language designed on top of an existing, generalized conceptual model for RBAC. The language sports a syntax close to natural language, to encourage its adoption among practitioners. We also define semantic checks to detect conflicts and inconsistencies among the policies written in a GemRBAC-DSL specification. We show how the semantics of GemRBAC-DSL can be expressed in terms of an existing formalization of RBAC policies as OCL (Object Constraint Language) constraints on the corresponding RBAC conceptual model. This formalization paves the way to define a model-driven approach for the enforcement of policies written in GemRBAC-DSL. [less ▲]

Web application firewalls (WAF) are an indispensable mechanism to protect online systems from attacks. However, the fast pace at which new kinds of attacks appear and their increasing sophistication require WAFs to be updated and tested regularly as otherwise they will be circumvented. In this paper, we focus our research on WAFs and SQL injection attacks, but the general principles and strategy could be adapted to other contexts. We present a machine learning-driven testing approach to automatically detect holes in WAFs that let SQL injection attacks bypass them. At the beginning, the approach can automatically generate diverse attacks (tests) and then submit them to a system that is protected by a WAF. Incrementally learning from the tests that are blocked or accepted by the WAF, our approach can then select tests that exhibit characteristics associated with bypassing the WAF and mutate them to efficiently generate new bypassing attacks. In the race against cyberattacks, time is vital. Being able to learn and anticipate more attacks that can circumvent a WAF in a timely manner is very important in order to quickly fix or fine-tune protection rules. We developed a tool that implements the approach and evaluated it on ModSecurity, a widely used WAF, and a proprietary WAF that protects a financial institution. Evaluation results indicate that our proposed technique is efficient at generating SQL injection attacks that can bypass a WAF and can be used to identify successful attack patterns. [less ▲]
