This report focuses on reviewing how lifelong learning strategies at an enterprise level influence the development of human capital. The conceptual analysis is to inform and guide semi-structured interviews conducted in LLLight’in’Europe’s (FP7) participating enterprises. As a first step towards contributing to the current research and theoretical paradigms in strategic human resource management, the report builds on current models, keeping in mind the intangibles of human capital, the pervasiveness and ubiquitous attributes of situated learning at different levels within enterprises.

In this paper, we study numerically the linear damped second-order hyperbolic partial differen-tial equation (PDE) with affine parameter dependence using a goal-oriented approach by finite element (FE) and reduced basis (RB) methods. The main contribution of this paper is the “goal-oriented” proper orthogonal decomposition (POD)–Greedy sampling procedure within the RB approximation context. First, we introduce the RB recipe: Galerkin projection onto a space YN spanned by solutions of the governing PDE at N selected points in parameter space. This set of N parameter points is constructed by the standard POD–Greedy sampling procedure already developed. Second, based on the affine parameter dependence, we make use of the offline-online computational procedures: in the offline stage, we generate the RB space; in the online stage, given a new parameter value, we calculate rapidly and accurately the space-time RB output of interest and its associated asymptotic error. The proposed goal-oriented POD–Greedy sampling procedure can now be implemented and will look for the parameter points such that it minimizes this (asymptotic) output error rather than the solution error (or, error indicator which is the dual norm of residual) as in the standard POD–Greedy procedure. Numerical results show that the new goal-oriented POD–Greedy sampling procedure improves significantly the accuracy of the space-time output computation in comparison with the standard POD–Greedy one. The method is thus ideally suited for repeated, rapid and reliable evaluation of input-output relationships within the space-time setting. [less ▲]

During the period from 7th until 14th February 2013 Norman Teferle (University of Luxembourg) and Seth White (Unavco Inc.) visited King Edward Point (KEP) research station, South Georgia, to establish the KEP Geodetic Observatory (KEPGO). The observatory consists of an autonomous, continuous Global Navigation Satellite System (GNSS) station with auxiliary equipment on Brown Mountain, as well as, benchmarks on Brown Mountain and at KEP research station. The primary objective of the observatory is to measure vertical land movements in order to study sea level changes using the KEP tide gauge record or satellite altimeter data. Therefore, the existing tide gauge was connected to the observatory through precise levelling and campaign GNSS observations. The levelling was carried out over the tide gauge itself, two existing United Kingdom Hydrographic Office (UKHO) and four newly established KEPGO tide gauge benchmarks (TGBMs). The GNSS observations were carried out on two benchmarks and their coordinates were computed with respect to the continuous GNSS station on Brown Mountain. Taking the UKHO height information together with the levelling and GNSS results it is suggested that the UKHO TGBM on the jetty may have settled by a few centimetres over the period from 2003 to 2013 and that the UKHO height datum requires a shift of by about -1 m in order to bring it closer to a globally consistent vertical reference system. This technical report details the installation work and analysis carried out during and after the visit. [less ▲]

The study deals with the practice of education and care for 0-4 year old children in the publicly funded daycare sector of Luxembourg by examining six selected crèches with the methods of ethnographic fieldwork. It describes the realities of care focusing on the question how professionals account for their educational significance in light of heterogeneous and at times also dilemmatic expectations of their services. Thus, the study contributes to debates on the educational quality of daycare facilities. In contrast to most other studies on tis subject, however, it does not presuppose what "education" is or should be. Rather, it understands education as a task that educational practice has to confront in order to assure itself as being educational and to represent itself as such in front of its audience. Empirically, the study is about practices of pedagogicalization. Theoretically, it is about aspects of the institutionalization of non-familial childcare. [less ▲]

The project, SUSTAIN_GOV, aims at investigating sustainable spatial development policies in the context of governance, both with respect to Luxembourg and, as a comparative ap-proach, to the Swiss planning system and urban transformation processes in the Glattal-Stadt. SUSTAIN_GOV builds directly from the strong conceptual and empirical foundations estab-lished by the “SUSTAINLUX Project” (CO9/SR/01) that has thus far shown that despite the intense urbanization pressure, the strong strains on land resources and infrastructure, and the political dilemmas these issues raise, policy, planning and governance practices in the Grand Duchy remain underdeveloped, particularly in the domain citizen involvement in public deci-sion-making. SUSTAIN_GOV brings into sharper focus a more nuanced scientific under-standing of participation, governance, and integrated sustainable spatial development, and an in-depth evaluation of existing spatial planning, policy, and governance patterns in the Grand Duchy. The proposed research is informed by a robust and contemporary set of conceptual approach, that shape current urban and regional literatures. The research design follows a qualitative methodological approach. [less ▲]

For sustainable growth, job creation and innovation, Luxembourg has chosen to rapidly develop high quality university and public research infrastructures and transition to a knowledge society. Europe, through its "Digital Agenda" has chosen to maximise the social and economic potential of ICT. In order to achieve these goals, high quality knowledge in all fields must be available not only for University and Research Centers but for the whole population. Lifelong learning and cultural commons need to be promoted actively. This was one of the motivations to modernise the library sector and to invest in new built infrastructures for the National Library and the University of Luxembourg. Though printed material will not disappear, a rapidly increasing amount will be in exclusively digital format (the focus of this document) either licensed from publishers, made accessible under Open Access regimes or through digitisation of printed originals. The internet continues to have a big impact on knowledge creation and cultural creativity through vastly facilitated networking and availability of very large amounts of information. The organisations endorsing this document have taken up the challenge to respond pro-actively to this evolution. This document is a guide to help readers understand a number of current challenges and opportunities for digital culture and science, relevant to libraries, research organisations as well as research and library funders.

In vielen europäischen Ländern haben Jugendliche zunehmend Probleme beim Übergang von der Schule in den Beruf. Die hohen Zahlen arbeitsloser Jugendlicher in vielen Ländern Europas verdeutlichen diesen Trend. Der vorliegende Bericht greift diese Entwicklung auf und beschäftigt sich mit den spezifischen Problemen und Risiken von Jugendlichen in Luxemburg beim Übergang auf den Arbeitsmarkt. In einem ersten Schritt werden die zentralen theoretischen Konzepte zur Beschreibung von Übergängen und Übergangsproblemen skizziert und kritisch erläutert. Davon ausgehend erfolgt für Luxemburg die differenzierte Beschreibung potentieller Problem- und Risikolagen von Jugendlichen. Die empirische Analyse erfolgt dabei auf der Grundlage vorhandener Daten (Sekundäranalyse). Der Blick wird nicht nur auf die Arbeitslosigkeit gerichtet, sondern auch auf die Situation Jugendlicher in Bildungs- und Arbeitsmaßnahmen, in prekärer Beschäftigung sowie auf Jugendliche, die inaktiv sind.

Le rapport politique sur les migrations et l’asile destiné au Réseau Européen des Migrations donne un aperçu des principaux débats politiques et développements dans ce domaine au Luxembourg au cours de l’année 2012. Si plusieurs sujets ont dominé le débat politique général comme la gestion de la crise économique, la réforme du système de pensions, ou encore la réforme du système d’enseignement, ces questions ont été thématisées le plus souvent sans qu’un lien ne soit établi avec la situation démographique particulière du Luxembourg caractérisée d’une part, par une population composée de 43% de non-nationaux et un emploi intérieur dont la maind’oeuvre étrangère, résidente ou transfrontalière, représente 68,5%. Dans ce contexte, trois thématiques ont dominé le débat politique en 2012 - les flux migratoires en relation avec la libre circulation des citoyens de l’Union européenne, l’accueil et l’aide sociale des demandeurs de protection internationale et le débat sur la réforme de la loi sur la nationalité.

Petri nets slicing is a technique that aims to improve the verification of systems modeled in Petri nets. Different Petri nets slicing constructions are studied along with algorithms to compute them. Petri nets slicing was first developed to facilitate debugging but then devel- oped for alleviating the state space explosion problem for model checking Petri nets. This article has twofold objectives, the first is to unify all the existing slicing algorithms syntactically by the definition of a standard abstract syntax and rewriting of the studied slicing algorithms using the proposed syntax. The second is to discuss the contribution of each slicing construction and comparing the major differences between them. One of the interesting exploitation of the survey is for the selection and im- provement of slicing techniques for approaches concerned by optimizing verification of state event models. [less ▲]

In the case of Luxembourg, the number of CBW continuously increased throughout the years and accounted to almost 42% of the domestic labour force in 2010 . Moreover and for the same reference year, Luxembourg’s nationals represented a share of 29% of the total labour force . Concretely, for 100 jobs available on the labour market, 27 were taken up by foreign residents, 29 occupied by Luxembourgers and 44 by CBWs . The present study focuses on TCN-CBWs. Indeed, if CBWs in general have been the subject of a range of studies due to their importance for the labour market in particular, TCN-CBWs have largely been ignored in public debates so far. Taking both a quantitative and a qualitative approach, the present study tries to shed some light on the main characteristics composing the profiles of TCN-CBWs. Thus, TCN-CBWs provide on average for the youngest labour force on the national labour market, the large majority are wage earners under permanent contract and highly skilled. On their motivations to work in Luxembourg, TCN-CBWs put forward in descendent order a) salary, b) possibilities for career development, c) job opportunities in Luxembourg, d) the international working context and e) the professional network . The study also enquires on their integration, migration trajectories and discrimination aspects and leads us to the conclusion that migration histories are eclectic and individual. Even if some traits can be common, such as being highly skilled, their live paths differ in many ways. [less ▲]

Eviter les ruptures de parcours des jeunes en situation de vulnérabilité, tel est l’objectif fixé par Haut commissariat à la Jeunesse dont s’est emparé le Conseil Général du Val-de-Marne, en partenariat avec la Protection Judiciaire de la Jeunesse, les missions locales et les association de prévention du département. Si l’Aide Social à l’Enfance et la Protection de la jeunesse s’interrogent sur le devenir des jeunes à la fin de leur prise en charge, la question de l’entrée dans l’âge adulte, l’objectif d’autonomie et d’insertion professionnelle sont une problématique partagée par l’ensemble des organisations partenaires. Après une étude approfondie des manques, besoins et potentiels des jeunes en matière de logement, de formation, d’emploi, de réseau social, de santé et d’accès à la mobilité, le comité technique composé des cadres des organisations porteuses du dispositif et des structures partenaires élaborent un dispositif expérimental : ROAD 94. Après de multiples échanges et tentatives, les bases du dispositif sont créées. Les situations de jeunes pour lesquels les référents manquent de moyen d’action à l’accompagnement sont exposées lors d’une commission. Au cours de celle-ci, les membres de la commission portent un regard réflexif sur la situation et échangent avec le référent, voire avec le jeune concerné. Des allocations financières ponctuelles ou mensuelles, des orientations vers des associations d’insertion par le logement, de parrainage, d’accès à la mobilité ainsi que des prises de rendez-vous pour des bilans médicaux sont proposées. Tout en suivant sa construction et sa mise en œuvre, et en observant l’ensemble des questions qu’elle a suscité, l’évaluation s’est fixée pour objectif de mesurer l’impact du dispositif sur les parcours et trajectoires des jeunes, ainsi que d’objectiver les logiques d’actions, les transformations et la manière dont peut se mettre en place et se maintenir une forme de partenariat. Orientés par l’ASE, la PJJ, les missions locales et les associations de prévention spécialisée, les jeunes ont le point commun d’être à des moments où ils doivent faire face à des changements, des séparations qui dans certains contextes, ou lorsqu’ils s’ajoutent à d’autres séparations ou changements, peuvent entrainer une rupture, faire basculer ces jeunes de la zone de vulnérabilité à une zone de disqualification sociale1. Concernant l’impact du dispositif sur les parcours des jeunes, nous pouvons noter une évolution ou une possibilité de maintien des situations de logement, de formation ou d’emploi pour la majorité des jeunes accompagnés. D’un point de vue plus compréhensif, le dispositif a permis aux jeunes de s’inscrire dans des « projets » adaptés aux moments de leur parcours, à leur capacité et possibilité de projection et à leurs expériences antérieures. L’outil commission, au-delà d’une fonction d’orientation et de conseil, a permis une appréhension plurielle du jeune, évitant ainsi un étiquetage lié au passage dans une institution repérée. En ce qui concerne les logiques d’action et les transformations des organisations, nous pouvons retenir quelques points qui doivent être pris en compte pour une éventuelle généralisation du dispositif. Un véritable partenariat a autorisé le passage de relais et l’augmentation du pouvoir d’acteur de chacun des professionnels de terrain. Ce partenariat a été rendu possible par un pilotage resserré du dispositif, la visibilité d’un projet d’envergure, le souci de communication sur celui-ci, l’intérêt d’un travail commun à toutes les organisations pour résoudre des problèmes rencontrés par chacune, l’intérêt aux différents échelons de l’organisation (par exemple, l’aspect formatif de la commission présentait un intérêt pour les référents de terrain), le rapport d’égalité permis dans l’espace temps de la commission, ainsi que le sentiment d’être acteur et porteur d’un dispositif, surtout du point de vue des cadres membres de la commission. Le travail de connaissance de l’ensemble des organisations travaillant de près ou de loin la question de l’insertion de la jeunesse sur le territoire, la collaboration des organisations porteuses du projet et les moyens financiers et matériels permettant d’agir pour favoriser l’expérimentation de la posture d’acteurs des jeunes accompagnés, tels peuvent être les axes à reprendre pour la mise en place d’autres dispositifs.

The purpose of this thesis is to investigate the use and benefit of visual modelling languages (VMLs) in modelling on tangible user interfaces (TUIs), and modelling TUI applications. Three main research questions are asked: - Is it possible and practical to model an application or process using a TUI? - Which General-purpose VML (GPVML) performs best in modelling a VML scenario for use on TUI? - Is it realistic to use a GPVML to model complex TUI applications? To answer the first research question, a Business Process Model and Notation, version 2 (BPMN2), ideation scenario is used with a tangible widget toolkit prototype on a TUI table to evaluate the performance and obtain feedback from test candidates. The study showed that it is possible to model a process using a TUI and the test candidate feedback did not lead to the conclusion that the modelling was cumbersome or impractical. To find a suitable GPVML, the thesis explores and evaluates the current state of the art in VMLs for describing general problems. After gathering different VMLs, the thesis compares three languages using a simple scenario: the visual object constraint language (VOCL), augmented constraint diagrams (ACD), and the visual contract language (VCL). A weighted evaluation based on multiple quality criteria led to the conclusion that VCL is best suited to model TUI applications, answering the second research question. The thesis answers the third research question by using VCL to model a more complex and complete scenario of an ideation process, which is based on using a BPMN2 on a TUI. This is done to assess VCL's suitability to more complex problems and its maturity. The study concludes that VCL is not yet mature enough to enable its general applicability in a wide variety of settings. The three research questions were dressed with a hypothesis in mind: collaborative, novice friendly modelling environments are able to reduce the gap between stakeholders and software engineers during software projects, leading to a reduction of unrealistic expectations and an increase in the availability of domain knowledge. While the hypothesis is too broad to be proven by this thesis, the research questions answered here give some insights into how to approach it. [less ▲]

The Ecological Footprint methodology by Global Footprint Network measures human consumption of products and services from different ecosystems in terms of the amount of bioproductive land and sea area needed to supply these products and services. In other words, the Ecological Footprint calculates the land area needed to produce food, provide resources, produce energy, and absorb the CO2 emissions generated by the supply chains within one year at country level. For the calculations of Luxembourg’s Ecological Footprint, international statistical databases are used to identify the quantities of produced, imported and exported goods and services. Then, Global Footprint Network applies different factors to the quantities to assess the area needed to supply these products and services. Finally, the Consumption Footprint of a nation is divided by the number of inhabitants and compared to other countries at a per capita level (global hectares per capita). This means that the Ecological Footprint can be used as an indicator for the sustainability of a national consumption by assessing human land uses. In the following paragraph, Luxembourg’s Ecological Footprint is discussed in the framework of the environmental indicators of Luxembourg’s competitiveness scoreboard (see Table 9) [MECE, 2010]. Luxembourg’s ranking is rather low for all of the scoreboard indicators: number of ISO 9001 certifications per billion of inhabitants (21 out of 27); number of ISO 14001 certifications per billion of inhabitants (15 out of 27); total greenhouse gas emissions (15 out of 27); renewable energy ration (23 out of 27); quantity of municipal waste per capita per year (24 out of 27); energetic intensity (8 out of 27); transport by car (17 out of 27); Ecological Footprint in gha per capita per year (27 out of 27). Based on the environmental competiveness scoreboard indicators, it can be concluded that in general, Luxembourg’s environmental performance is low compared to the other countries of the European Union. With respect to Luxembourg’s Ecological Footprint, it can be said that Luxembourg’s consumption is not sustainable. The number of planets that would be needed if the world's population lived like the population of Luxembourg in 2007 is about six. However, per year, the biocapacity (bioproductive land) of the planet can only regenerate once. [less ▲]

Vast amount of news articles are published daily reflecting global topics. The stories represent information about events and expert opinions, which may trigger positive or negative expectations on the stock markets. The literature describes various methods for analyzing such correlations. In this paper we consider related approaches for tracking the impact of news on abnormal stock returns. In the first part we introduce studies with back- ground in Finance. Primarily by applying statistical functions the works examine unusual price volatilities and explore possible sources and market conditions, e.g. biased investors, limited attention, macro-economic variables, country development state, et cetera. In the second part we present studies with background in Computer Science, which take advan- tage of historic news and the equivalent market values. By following the common learning paradigm the projects elaborate prototypes for trend and stock price prediction. In the current survey we evaluate leading approaches regarding the objectives, assumptions, in- put, techniques, and performance. Moreover we provide a comparison framework of the recent prototypes and identify gaps for future research. [less ▲]

L'étude internationale "Health Behaviour in Schoolaged Children (HBSC)" de l'Organisation mondiale de la santé (OMS) a été menée dans les écoles de l'enseignement secondaire (et primaire) luxembourgeois et un premier rapport en a été publié sous l'intitulé "Das Wohlbefinden der Jugendlichen in Luxemburg". L’échantillon de l’étude comprend uniquement des adolescents scolarisés. Par cette approche, les jeunes en âge scolaire, ne fréquentant pas ou seulement irrégulièrement l’école, sont sous-représentés. Or, afin d’améliorer l’accès au bien-être et à la santé ainsi qu’à l’information y liée, il est important d’identifier les facteurs qui influencent les comportements de santé des jeunes en général et de ceux qui vivent des conditions difficiles en particulier. Par conséquent, il est indispensable d’étudier les jeunes dans la diversité de leurs réalités individuelles, familiales et sociales. Dans un but d’améliorer la représentativité de l’analyse et de faciliter aux professionnels concernés le développement de mesures concrètes de prévention, adaptés aux besoins spécifiques des jeunes, il nous semble important de répliquer l’enquête dans une optique comparative et analytique auprès de groupes de jeunes sous-représentés dans l’étude initiale. Il s’agit notamment de jeunes en situations individuelle, familiale et sociale difficiles et engagés dans des trajectoires vulnérables, comme par exemple des jeunes ayant abandonnés précocement l’école, des toxicomanes ou des jeunes placés dans un centre socio-éducatif.

In this paper we claim that a widely applicable and efficient means to fight against malicious mobile Android applications is: 1) to perform runtime monitoring 2) by instrumenting the application bytecode and 3) in-vivo, i.e. directly on the smartphone. We present a tool chain to do this and present experimental results showing that this tool chain can run on smartphones in a reasonable amount of time and with a realistic effort. Our findings also identify challenges to be addressed before running powerful runtime monitoring and instrumentations directly on smartphones. We implemented two use-cases leveraging the tool chain: FineGPolicy, a fine-grained user centric permission policy system and AdRemover an advertisement remover. Both prototypes improve the privacy of Android systems thanks to in-vivo bytecode instrumentation. [less ▲]
