We consider the solution of a multivariate stochastic differential equation with Levy-type jumps and with unique invariant probability measure with density μ. We assume that a continuous record of observations is available. In the case without jumps, Reiss and Dalalyan [7] and Strauch [24] have found convergence rates of invariant density estimators, under respectively isotropic and anisotropic H ̈older smoothness constraints, which are considerably faster than those known from standard multivariate density estimation. We extend the previous works by obtaining, in presence of jumps, some estimators which have the same convergence rates they had in the case without jumps for d ≥ 2 and a rate which depends on the degree of the jumps in the one-dimensional setting. We propose moreover a data driven bandwidth selection procedure based on the Goldenshluger and Lepski method [11] which leads us to an adaptive non-parametric kernel estimator of the stationary density μ of the jump diffusion X.

Biomass as a renewable energy source continues to grow in popularity to reduce fossil fuel consumption for environmental and economic benefits. In the present contribution, the combustion chamber of a 16 MW geothermal steam super-heater, which is part of the Enel Green Power "Cornia 2" power plant, is being investigated with high-performance computing methods. For this purpose, the extended discrete element method (XDEM) developed at the University of Luxembourg is used in a high-performance computing environment, which includes both the moving wooden bed and the combustion chamber above it. The XDEM simulation platform is based on a hybrid four-way coupling between the Discrete Element Method (DEM) and Computational Fluid Dynamics (CFD). In this approach, particles are treated as discrete elements that are coupled by heat, mass, and momentum transfer to the surrounding gas as a continuous phase. For individual wood particles, besides the equations of motion, the differential conservation equations for mass, heat, and momentum are solved, which describe the thermodynamic state during thermal conversion. The consistency of the numerical results with the actual system performance is discussed in this paper to determine the potentials and limitations of the approach. [less ▲]

A largely forgotten constcamer painting from the early seventeenth century shows eyeglasses and a telescope in close proximity. The inclusion of these extensions of sight in The Five Senses of the Musée Magnin (Dijon) seems to allude to the implicit link between the two. As tools to observe with and through, these instruments visualize the limits of human perception and the ability to alter the scale of the visible world. The Five Senses was created in Antwerp around the same time the telescope first appeared in textual sources, namely 1608. However, the optical instrument is likely to have existed for years by then. This paper investigates if any references to the telescope in the visual arts predate the first written evidence of its invention. For artists the early telescope was probably not that challenging an object to represent. The exterior, a simple tube characterized by a diaphragm, housed two lenses made by the same glass industry that manufactured eyeglasses. This paper takes a closer look at the imagery of eyeglasses and telescopes, depicted in the visual arts of the late sixteenth and early seventeenth centuries. The meaning assigned to these instruments can be inferred from the context in which they are presented and their relative scale. Together eyeglasses and telescopes feature prominently in constcamer paintings dedicated to visual perception, understood both physically and metaphysically. While the exact date of creation remains subject to debate, The Five Senses probably contains the earliest known depiction of a telescope – true to scale. [less ▲]

Increased migration has led to the formation of culturally diverse societies in many places around the world. The concept of Multicultural Ideology incorporates two values as a way to promote positive intercultural relations: a) Diversity: the presence of ethnocultural diversity in the population and b) Equity: the right for equal participation of all cultural groups in the society. Both diversity and equity are necessary conditions for the success of multicultural policies. Culturally heterogeneous communities that do not support inclusion and equitable participation of all groups face the negative consequences of segregation and marginalization. In line with this notion, an international research consortium is developing a revised version of the Multicultural Ideology Scale to assess the endorsement of multicultural ideology in different national contexts. The scale aims to distinguish various attitudinal dimensions of multiculturalism, relevant to the acceptance of diversity and social inclusion of different ethnocultural groups: Cultural Maintenance, Social Interaction, Equity/Inclusion, Extent of Differences, Conflictual Relations, Essentialistic Boundaries. We present the first assessment of the new scale in the German language. The survey was administered online to a sample of native German citizens (N = 382) with different demographic characteristics. Our aim was to understand the attitude of native citizens towards cultural diversity and their willingness to have members of ethnic minority groups be included in the larger society. We investigated the factor structure of the scale, its psychometric properties, and the relationship between multicultural ideology and some individual difference variables, such as ethnic group attachment and social dominance orientation.

Social service providers in the Greater Region report that many children in need of special care and social assistance find themselves in cross-border situations. The legal regulations and practices for the care of children and adolescents can vary considerably from country to country. This can cause delays, breaks or deterioration in the quality of support and sometimes irreversibly worsen the child's situation. Depending on the situation, diagnoses and access to social, medical-social or legal services can change considerably. The EURQUA project deals with cross-border child protection and disability rights within a multinational perspective. [less ▲]

The legal sector is being hit by profound economic and technological changes (digitalization, open data, blockchain, artificial intelligence ...) forcing law firms and legal departments to become ever more creative in order to demonstrate their added value. To help lawyers meet this challenge, this book draws on the perspectives of lawyers and creative specialists to analyze the concept and life cycle of legal innovations, techniques and services, whether related to legislation, legal engineering, legal services, or legal strategies, as well as the role of law as a source of creativity and interdisciplinary collaboration.

The Sustainable Development Goals (SDGs) re-focused development cooperation on universal and transformative development aimed at improving the quality of life of people in all world regions, while simultaneously conserving natural resources. Critics, however, have correctly questioned whether appropriate policy methods and tools exist for the adequate implementation of transformative development. These challenges are even more significant given that the implementation of the SDGs falls to nation-states. This article asks “Can the transformative development promoted by the SDG’s be achieved through the policy tools presently utilized by nation-states, such as environmental impact assessment (EIA)?” The study responds to this question through a critical examination of EIA in Mexico in relation to mining. Empirical analysis focuses on the proposed Caballo Blanco open-pit mine in Veracruz state. The case can be considered critical because it is often presented as a success, given that a broad coalition of actors prevented the mine from opening through activities directed at EIA. This article questions this narrative because it shows how EIA actually can undermine transformative development through the use of cost-benefit logics. The article concludes that policy coherence for development (PCD) can potentially support EIA as a methodology through which transformative development can be promoted. PCD can improve the “normative effectiveness” of EIA when used as an evaluation criteria. Otherwise, EIA may undermine the implementation of the SDGs which would be comparable to serving soup with a fork. [less ▲]

This chapter undertakes a critical assessment of the accountability of one recent institutional addition to the Euro area governance system – the European Stability Mechanism (ESM). Regarding Euro area governance in general, Dawson (2015: 976) warns that many new structures designed in response to the Euro area crisis ‘depart from the mechanisms of legal and political accountability present in previous forms of EU decision-making without substituting new models of accountability in their place’. By examining in greater detail the financial accountability mechanisms applicable to an important new Euro area body, we identify accountability gaps and shortcomings in the complex EU architecture of financial control.
