This paper aims to investigate the concept, context and socio-economic consequences of fiscal competition in the integrated economic space of EMU in completion, to pinpoint the positive and negative factors at work via a case study of the Benelux countries – both founder members of the EU and pioneers of EMU – and to examine the impact on European and international regulations in the field. In particular, it will endeavour to provide a comprehensive interpretation of fiscal policy in the Benelux countries via a comparative approach and from a historical perspective. It will look at the development of respective domestic fiscal policies, driven by national interests and by membership of a Community that is subject to requirements in terms of harmonisation and taxation, but also by constant contact (and frequent clashes) with the multilateral international environment.

Flow-driven piezoelectric energy harvesting is a strongly coupled multiphysics phenomenon that involves complex three-way interaction between the fluid flow, the electromechanical effect of the piezoelectric material mounted on a deformable substrate structure and the controlling electrical circuit. High fidelity computational solution approaches are essential for the analysis of flow-driven energy harvesters in order to capture the main physical aspects of the coupled problem and to accurately predict the power output of a harvester. While there are some phenomenological and numerical models for flow-driven harvesters reported in the literature, a fully three-dimensional strongly coupled model has not yet been developed, especially in the context of flow-driven energy harvesting. The weighted residuals method is applied to establish a mixed integral equation describing the incompressible Newtonian flow, elastic substrate structure, piezoelectric patch, equipotential electrode and attached electric circuit that form the multiphysics fluid-structure interaction problem. A monolithic numerical solution method is derived that provides consistent and simultaneous solution to all physical fields as well as to fluid mesh deformation. The approximate solution is based on a mixed space-time finite element discretization with static condensation of the auxiliary fields. The discontinuous Galerkin method is utilized for integrating the monolithic model in time. The proposed solution scheme is illustrated in the example of a lid driven cavity with a flexible piezoelectric bottom wall, demonstrating quantification of the amount of electrical energy extractable from fluid flow by means of a piezoelectric harvester device. The results indicate that in order to make reliable predictions on the power output under varying operational states, the realization of strong multiphysics coupling is required for the mathematical model as well as the numerical solution scheme to capture the characteristics of flow-driven energy harvesters.

The solemnly proclaimed European Pillar of Social Rights provides a meaningful response to the process of building a deeper, fairer European Union in the aftermath of the crisis. This chapter aims to provide a critical assessment of the nature, scope, rationale, purpose, content and effectiveness of the Pillar in the light of its potential contribution to foster social fairness and competitiveness in the EU. The Pillar complements and develops the EU’s social acquis and reinforces standards which may provide a fairer and more socially-balanced competitiveness in the EU. Progress has been made, but further efforts are needed to build a sense of common purpose to strengthen the social foundations of the Union. [less ▲]

It is commonly known that experiencing conflict can have negative impact on an individuals’ physical and mental health. Especially in intimate relationships, conflict has great influence on the well-being of both partners. Since intercultural intimate relationships are associated with both exceptional obstacles and benefits, conflict behavior in those relationships is of substantial interest in this research project. The aim of this study is to investigate how conflicts in intimate relationships are affected by the partners’ cultural backgrounds and linguistic barriers. It further seeks to unravel how conflict resolution is approached in order to provide a broader knowledge base in this field. For the purpose of this research, four semi-structured interviews with two couples were conducted individually. Each couple was interviewed by a different researcher. Ensuing, the interviews were transcribed and afterwards the data was analyzed implementing qualitative content analyses. The results provide insight into different levels of relationship functioning, sources of conflict as well as conflict resolution. Therefore, the findings of this study may have important implications for clinical practice. [less ▲]

Recently, some resourceful community-driven initiatives for local food production and retail have arisen in Luxembourg, where low organic agricultural rates are paradoxically paired with high consumer demands. This niche of social innovators is combining agro-ecology with circular economy practices. Four cases of alternative food networks are of interest – studied with qualitative interviews and participant observation. One has been established since the 1980s with 200 employees, partly in social insertion measures. The more recent and smaller initiatives are characterized by a cooperative governance, a community-supported agricultural outlook, hands-on workshops and time-banks, all enabled by social media. These initiatives are more radical in their agro-ecological or permaculture practices, focusing on regenerative land use without relying on imports and fostering the integration of consumers with varying degrees of prosumer involvement, as a politicized step further than mere (possibly industrialized) organic production.

„Die Liebe verwundet, die Liebe fesselt, die Liebe macht krank, die Liebe lässt schwach werden.“ Dieser ursprünglich theologisch geprägte Gedanke über die Gewalt der Liebe, lässt sich – auf seinen bildlichen Kern reduziert – in zahllosen Varianten in der Weltliteratur aufspüren. Eine besonders auffällige Form scheinen dabei jene Texte zu bieten, die Liebe nicht allein als Auslöser, sondern gar selbst als Krankheit darstellen – zumindest implizit, insofern der Zustand des Verliebtseins mit dem Zustand der Krankheit gleichgesetzt wird. Wohl bekannt sind die körperlichen Symptome dieses Liebeszustandes, die in ihrer klassischen Ausprägung im Erbleichen, Erröten, Zittern, in Sprachlähmung sowie im Bluten aus der Nase bestehen und im Mittelalter als minnesiech bezeichnet werden. Erscheint die Liebeskrankheit im Minnesang noch vornehmlich in metaphorischem Gebrauch (s. das gequälte Herz als Beispiel für den Schmerz der Minne), weisen spätere Wörterbucheinträge (vgl. hierzu die Lemmata ‚Liebesfieber’ oder ‚Jungfernkrankheit’) wiederum auf ein stärker körperlich-physiologisches und auch sexuell-erotisches Verständnis von Liebe hin. Krank macht die Minne nun vor allem – und dem mittelalterlichen medizinischen Duktus der Humoralpathologie folgend – dann, wenn das körperliche Begehren nicht befriedigt werden kann. Der hier skizzierte Vortrag will die Vorstellung von Krankheit in einem größeren semantischen Beziehungsgeflecht in den Blick nehmen, das sich in der mhd. Lyrik in bedeutender Weise hervortut: der Verbindung Liebe – Krankheit – Wahn. Der wân als zentrales Symptom der Minnekrankheit löst – so die hier zu erprobende These –den Geist vom versehrten Körper und definiert damit den Übergang von der körperlichen Krankheit(smetapher) zu einer seelischen Zustandsbeschreibung. Die sprachhistorische Herleitung von mhd. wân vermag diese Beobachtung weiter zu untermauern, insofern der Begriff ein zunächst wertneutrales, semantisch vielfältiges Bedeutungsspektrum impliziert, und sich mit ‚Hoffnung, Zuversicht oder Einbildungskraft’ ins Nhd. übertragen ließe. Im krankhaften Minne-wân öffnen sich Denkräume, denen der Minnesang eine literarische Ausgestaltung verleiht; Minne-wân führt damit nicht nur zu körperlicher Versehrtheit, sondern ist eben auch guoter wân, lieber wân, saelden wân – und damit einer der ersten ‚Testräume’ für die Erprobung gedanklicher Spielarten des lyrischen Ichs in der deutschen Dichtung überhaupt.

Gravel wash mud (GWM), a waste product from gravel mining was dried and processed into a fine powder to be activated by different concentrations of sodium hydroxide (NaOH) solutions for the synthesis of an alkali-activated binder. The GWM powders were thermally treated at five different calcination temperatures 550, 650, 750, 850 and 950°C. The characterisation of the raw material comprises the particle size distribution (PSD) by laser granulometry, the chemical and mineralogical composition by X-ray fluorescence and X-ray diffraction analysis respectively, and simultaneous thermal analysis. The performance of the alkali-activated binders was examined using compression strength tests and the microstructure was observed using scanning electron microscopy (SEM). The GWM was classified as an aluminosilicate raw material with kaolinite and illite as main clay minerals. Furthermore, a mean particle size around 6.50μm was determined for the uncalcined and calcined GWM powders. The SEM images of the developed binders showed the formation of a compact microstructure, however, relatively low strengths were achieved. This preliminary study highlights an example of an aluminosilicate prime material, which shows very promising chemical and mineralogical characteristics, but its suitability for alkaline activation without further additives was not confirmed as far as performance-based criteria are considered.

In the present paper, a model-based fault/attack tolerant scheme is proposed to deal with cyber-threats on Cyber Physicals Systems. A common scheme based on observers is designed and a state feedback control based on an event-triggered framework is given with control synthesis and condition on the switching time. An event-based implementation is proposed in order to achieve novel security strategy. Observer and controller gains are deduced by solving su cient Bilinear Matrix Inequality (BMI) condition. Simulation results on a real-time laboratory three tank system are given to show the attack-tolerant control ability despite data deception attacks on both actuators and sensors. [less ▲]
