Against the backdrop of the ongoing crisis-led migration from Southern to Northwestern Europe, the present paper reports on a case study of two families who have recently migrated from Greece to Luxembourg. Luxembourg has a trilingual education system and many pupils of migrant background face difficulties on this account. Drawing on the framework of Family Language Policy, this paper explores the language ideologies and management strategies of two families as well as factors influencing their policies. This qualitative study was based on interviews, observations, and videos recorded by one of the families. The findings show that the families have contrasting language ideologies and management strategies that are informed by their differing transnational experiences, competences and worldviews. This study can contribute to a better understanding of the ways in which migrant families use their language resources in their new country. [less ▲]

The present volume deals with the experience of ambivalence in family relations - a well-known phenomenon that has inspired more and more research and theorizing in the last years but that is however sometimes difficult to capture. Bringing together junior and senior researchers from different parts of the world, ideas on theory and research are elaborated following qualitative and quantitative approaches. This book thus contributes to theory-building as well as outlining research results and helping to develop measurement in interpersonal and intergenerational relations. [less ▲]

Abstract Deep brain stimulation (DBS) is a neurosurgical intervention where electrodes are permanently implanted into the brain in order to modulate pathologic neural activity. The post-operative reconstruction of the DBS electrodes is important for an efficient stimulation parameter tuning. A major limitation of existing approaches for electrode reconstruction from post-operative imaging that prevents the clinical routine use is that they are manual or semi-automatic, and thus both time-consuming and subjective. Moreover, the existing methods rely on a simplified model of a straight line electrode trajectory, rather than the more realistic curved trajectory. The main contribution of this paper is that for the first time we present a highly accurate and fully automated method for electrode reconstruction that considers curved trajectories. The robustness of our proposed method is demonstrated using a multi-center clinical dataset consisting of N=44 electrodes. In all cases the electrode trajectories were successfully identified and reconstructed. In addition, the accuracy is demonstrated quantitatively using a high-accuracy phantom with known ground truth. In the phantom experiment, the method could detect individual electrode contacts with high accuracy and the trajectory reconstruction reached an error level below 100 μm (0.046 ± 0.025 mm). An implementation of the method is made publicly available such that it can directly be used by researchers or clinicians. This constitutes an important step towards future integration of lead reconstruction into standard clinical care. [less ▲]

Flexible job-shop scheduling problem (FJSP) is an extension of the classical job shop scheduling problem where an operation can be processed by several different machines. The FJSP contains two sub-problems, namely machine assignment problem and operation sequencing problem. In this paper, we propose and compare a discrete firefly algorithm (FA) and a genetic algorithm (GA) for the multi-objective FJSP. Three minimization objectives are considered, the maximum completion time, workload of the critical machine and total workload of all machines. Five well-known instances of FJSP have been used to evaluate the performance of the proposed algorithms. Comparisons among our methods and state-of-the-art algorithms are also provided. The experimental results demonstrate that the FA and GA have achieved improvements in terms of efficiency. Solutions obtained by both algorithms are comparable to those obtained by algorithms with local search. In addition, results show that the proposed discrete firefly algorithm is feasible, more effective and efficient than the proposed genetic algorithm for solving multi-objective FJSP. [less ▲]

Among the roughly 150,000 soldiers sent to the Dutch East Indies between 1815 and 1914, the Luxembourg contingent made up a tiny minority of just 1,075 men. Based upon extensive research into their careers, data on these soldiers provide further clues to understanding what drove Europe’s young men to become colonial soldiers. The results of this national case study will be compared with earlier investigations by Bossenbroek and Bosma on recruits for the Dutch colonial army. Similar to the Dutch soldiers, their Luxembourg counterparts had a predominantly urban provenance. However, in contrast to the Dutch, they did not have a strong military background, and it appears that fewer Luxembourgers stayed behind in the Dutch East Indies after their tour of duty. They were more attracted by the payments that the recruiters doled out in advance, particularly at a time of economic crisis, than in a career in the tropics. [less ▲]

Series of workshops tailored towards early-career researchers in Luxembourg explaining the publishing process and how Open Access fits in the traditional journal-subscription based model. The idea is to break some of the myths around OA (e.g. OA is a journal, OA is only possible the gold way) by presenting the 'Green' (self-archiving) and 'gold' (paying Article Processing Charges) routes. Some of the benefits are presented, along with the main Luxembourgish funder FNR's mandate.

South Georgia Island in the Southern Atlantic Ocean has been a key location for the seismic, geomagnetic and oceanic global monitoring networks. However, no permanent geodetic monitoring station had been established there despite the lack of observations from this region within, for example, the International GNSS Service (IGS) network of Global Navigation Satellite System (GNSS) stations. Then, in 2013 the King Edward Point (KEP) Geodetic Observatory was established with a focus on sea level studies and in support of general geoscience applications. Currently, this observatory located roughly half-way along the main island and along its northern coastline, consists of two GNSS stations (KEPA and KRSA) with local benchmark networks, allowing the height determinations from the GNSS antennas to be transferred to the KEP tide gauge (GLOSS ID 187) and forming a height reference within the International Terrestrial Reference Frame. In late 2014, three additional GNSS stations (SG01, SG02 and SG03) were established, all on small islands at the perimeter of the main island. Together the stations provide the best possible opportunity to study various geophysical processes in the region. With the GNSS-derived position time series partly reaching over 4.5 years in length, it has become possible to provide first estimates of vertical land movements for the island and KEP with its surrounding area. Together with four precise levelling campaigns of the benchmark network in 2013, 2014 and two in 2017, it has also been possible to investigate the very local character of the vertical motions, ie. the stability of the jetty upon which the tide gauge is mounted. Our measurements show that while South Georgia Island and the area around KEP are rising, the jetty and tide gauge are subsiding. In this study, we will present the preliminary results from the GNSS and levelling measurements and will discuss their impact on the sea level record from the KEP tide gauge which is ideally situated in a mid-ocean location for satellite altimetry calibration over the Southern Atlantic and Southern Oceans.

In der international vergleichenden Forschung zu Gesundheitssystemen spielt der Zugang zu Gesundheitsleistungen eine zentrale Rolle. Entsprechende Typologien klassifizieren Gesundheitssysteme u.a. danach, ob Patienten Zuzahlungen leisten müssen, ob sie sich bei Hausärzten einschreiben müssen und nach welchen Regeln sie einen Facharzt konsultieren können (z.B. Reibling 2010, Wendt 2009, Böhm et al 2013). In der Typologie von Wendt gehört Österreich zum „Health service provision-oriented type“, der fast der gesamten Bevölkerung einen einfachen Zugang zu Gesundheitsleistungen bei geringen Zuzahlungen und freier Arztwahl ermöglicht (2009). Diese Typologien basieren jedoch auf den gesetzlichen Zugangsregeln in einem Land, nicht auf den subjektiven Erfahrungen der Bevölkerung mit Zugangsbarrieren. Im aktuellen European Social Survey (ESS) wurde nach diesen Barrieren gefragt: Haben Befragte medizinische Behandlungen nicht bekommen und was waren die Gründe (z.B. Kosten, Behandlung nicht erhältlich, Warteliste zu lang)? Der Vortrag stellt die Ergebnisse des ESS vor und geht auf folgende Fragen ein: • Wie häufig stoßen Kranke in Österreich und in anderen europäischen Ländern auf Zugangsbarrieren? • Welche Personen in Österreich sind besonders von Zugangsbarrieren betroffen? Die vorläufigen Ergebnisse deuten darauf hin, dass es durchaus nennenswerte Zugangsbarrieren im Gesundheitssystem Österreichs gibt und dass ohnehin benachteiligte Personen häufiger als andere auf Zugangsbarrieren stoßen. Für die wissenschaftliche Theorie stellt sich die Frage, ob die gängigen Typologien von Gesundheitssystemen um die subjektiven Erfahrungen ergänzt werden müssen. Für die Praxis stellt sich die Frage, wie schädlich Zugangsbarrieren sind und wie sie abgebaut werden können. [less ▲]

The authors’ first challenge is to decipher the complexity of Islamic Finance despite the opacity of the sector. A second focal point is the agent’s agenda; in the Islamic Finance industry, contributors mandate intermediaries (agents) to transfer their contributions to social causes according to the Shariah; in principle, Islamic financial institutions must create value for their stakeholders by offering Shariah-compliant products and services. An underlying assumption of agency theory is that agents attempt to maximize their personal welfare and compensation, but such behaviour may not always be in the best interests of other stakeholders, and an analysis of the agent’s agenda can help explain how agents can fall off the pedestal of altruism. Relationships between Islamic banks and three key stakeholders (contributors, beneficiaries and regulators) are also explored via a complexity-aware monitoring process. Contributors provide funds to an Islamic bank (agent), and in return, the agent should be accountable to the contributors, but the form and degree of accountability can vary depending on the organization’s mission. There are many unanswered questions regarding the monitoring process. One objective of the article is to consider whether agents act in the best interests of the stakeholders. Finally, the authors explore the following question: Can blockchain technology and smart contracts support and enhance the transparency feature, which is the core underlying principle of all transactions in the Islamic Finance industry? A qualitative research framework was adopted because of the constraints of the enigmatic, secretive Islamic Finance culture. [less ▲]

Despite of the known gap from the Shannon's capacity, several standards are still employing QAM or star shape constellations, mainly due to the existing low complexity detectors. In this paper, we investigate the low complexity detection for a family of QAM isomorphic constellations. These constellations are known to perform very close to the peak-power limited capacity, outperforming the DVB-S2X standard constellations. The proposed strategy is to first remap the received signals to the QAM constellation using the existing isomorphism and then break the log likelihood ratio computations to two one dimensional PAM constellations. Gains larger than 0.6 dB with respect to QAM can be obtained over the peak power limited channels without any increase in detection complexity. Our scheme also provides a systematic way to design constellations with low complexity one dimensional detectors. Several open problems are discussed at the end of the paper. [less ▲]

Banquier, penseur de la finance internationale et Européen convaincu, Alexandre Lamfalussy (1929-2015) est, sans conteste, l’un des architectes de l’euro. Dans ses jeunes années, il s’intéresse à l’intégration européenne et aux questions financières et monétaires. Lorsqu'il devient banquier, notamment au sein de la BRI (1976-1993), est l’un des premiers à alerter contre l’accumulation des dettes en Amérique latine et à préconiser une meilleure régulation internationale pour éviter les excès. Il fait de la surveillance macro-prudentielle des systèmes financiers un objectif central de la BRI. À la fin des années 1980, il devient memrbe du Comité Delors sur l’UEM, avant de devenir le premier président de l’Institut monétaire européen (IME) (1994-1997) et de préparer la création de la Banque centrale européenne (BCE). En 2000 il préside le « Comité des Sages » qui propose une nouvelle régulation des marchés financiers européens - le "processus Lamfalussy". Sous l’égide du G20, il participe à l’«initiative du Palais-Royal » pilotée par Michel Camdessus et Tommaso Padoa-Schioppa, qui avance une réforme complète du Système monétaire international (SMI).
