In this technical report, we present an application of the structured argumentation methodology to a debate in the foundations of mathematics. We work with ASPIC-END, a recently proposed adaptation of the structured argumentation framework ASPIC+ which can incorporate debates about logical principles, natural deduction style arguments and explanations. We apply this framework to build a preliminary formal model of parts of the debate that mathematicians had about the Axiom of Choice in the early 20th century. Furthermore, we briefly discuss the insight into the strengths and drawbacks of the modeling capacities of ASPIC-END that we have gained from producing this model. [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 ▲]

Abstract Background The purpose of the present study was to compare the mechanical static and fatigue strength of the size 2 osteotomy plate “Activmotion” with the following five other common implants for the treatment of medial knee joint osteoarthritis: the TomoFix small stature, the TomoFix standard, the Contour Lock, the iBalance and the second generation PEEKPower. Methods Six fourth-generation tibial bone composites underwent a medial open-wedge high tibial osteotomy (HTO), according to standard techniques, using size 2 Activmotion osteotomy plates. All bone-implant constructs were subjected to static compression load to failure and load-controlled cyclic fatigue failure testing, according to a previously defined testing protocol. The mechanical stability was investigated by considering different criteria and parameters: maximum forces, the maximum number of loading cycles, stiffness, the permanent plastic deformation of the specimens during the cyclic fatigue tests, and the maximum displacement range in the hysteresis loops of the cyclic loading responses. Results In each test, all bone-implant constructs with the size 2 Activmotion plate failed with a fracture of the lateral cortex, like with the other five previously tested implants. For the static compression tests the failure occurred in each tested implant above the physiological loading of slow walking (> 2400 N). The load at failure for the Activmotion group was the highest (8200 N). In terms of maximum load and number of cycles performed prior to failure, the size 2 Activmotion plate showed higher results than all the other tested implants except the ContourLock plate. The iBalance implant offered the highest stiffness (3.1 kN/mm) for static loading on the lateral side, while the size 2 Activmotion showed the highest stiffness (4.8 kN/mm) in cyclic loading. Conclusions Overall, regarding all of the analysed strength parameters, the size 2 Activmotion plate provided equivalent or higher mechanical stability compared to the previously tested implant. Implants with a metaphyseal slope adapted to the tibia anatomy, and positioned more anteriorly on the proximal medial side of the tibia, should provide good mechanical stability. [less ▲]

Abstract Background Results of finite element (FE) analyses can give insight into musculoskeletal diseases if physiological boundary conditions, which include the muscle forces during specific activities of daily life, are considered in the finite element modelling. So far, many simplifications of the boundary conditions are currently made. This study presents an approach for FE modelling of the lower limb for which muscle forces were included. Method The stance phase of normal gait was simulated. Muscle forces were calculated using a musculoskeletal rigid body (RB) model of the human body, and were subsequently applied to a FE model of the lower limb. It was shown that the inertial forces are negligible during the stance phase of normal gait. The contact surfaces between the parts within the knee were modelled as bonded. Weak springs were attached to the distal tibia for numerical reasons. Results Hip joint reaction forces from the RB model and those from the FE model were similar in magnitude with relative differences less than 16%. The forces of the weak spring were negligible compared to the applied muscle forces. The maximal strain was 0.23% in the proximal region of the femoral diaphysis and 1.7% in the contact zone between the tibia and the fibula. Conclusions The presented approach based on FE modelling by including muscle forces from inverse dynamic analysis of musculoskeletal RB model can be used to perform analyses of the lower limb with very realistic boundary conditions. In the present form, this model can be used to better understand the loading, stresses and strains of bones in the knee area and hence to analyse osteotomy fixation devices. [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 ▲]

The structure signature of a system made up of n components having continuous and i.i.d. lifetimes was defined in the eighties by Samaniego as the n-tuple whose k-th coordinate is the probability that the k-th component failure causes the system to fail. More recently, a bivariate version of this concept was considered as follows. The joint structure signature of a pair of systems built on a common set of components having continuous and i.i.d. lifetimes is a square matrix of order n whose (k,l)-entry is the probability that the k-th failure causes the first system to fail and the l-th failure causes the second system to fail. This concept was successfully used to derive a signature-based decomposition of the joint reliability of the two systems. In the first part of this paper we provide an explicit formula to compute the joint structure signature of two or more systems and extend this formula to the general non-i.i.d. case, assuming only that the distribution of the component lifetimes has no ties. We also provide and discuss a necessary and sufficient condition on this distribution for the joint reliability of the systems to have a signature-based decomposition. In the second part of this paper we show how our results can be efficiently applied to the investigation of the reliability and signature of multistate systems made up of two-state components. The key observation is that the structure function of such a multistate system can always be additively decomposed into a sum of classical structure functions. Considering a multistate system then reduces to considering simultaneously several two-state systems. [less ▲]
