In this paper, we introduce the concept of ‘societal emotional environment’: the emotional climate of a society (operationalized as the degree to which positive and negative emotions are expressed in a society). Using data collected from 12,888 participants across 49 countries, we show how societal emotional environments vary across countries and cultural clusters, and we consider the potential importance of these differences for well-being. Multilevel analyses supported a ‘double-edged sword’ model of negative emotion expression, where expression of negative emotions predicted higher life satisfaction for the expresser but lower life satisfaction for society. In contrast, partial support was found for higher societal life satisfaction in positive societal emotional environments. Our study highlights the potential utility and importance of distinguishing between positive and negative emotion expression, and adopting both individual and societal perspectives in well-being research. Individual pathways to happiness may not necessarily promote the happiness of others. [less ▲]

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 ▲]

Let $X$ be a nonempty set. Denote by $\mathcal{F}^n_k$ the class of associative operations $F\colon X^n\to X$ satisfying the condition $F(x_1,\ldots,x_n)\in\{x_1,\ldots,x_n\}$ whenever at least $k$ of the elements $x_1,\ldots,x_n$ are equal to each other. The elements of $\mathcal{F}^n_1$ are said to be quasitrivial and those of $\mathcal{F}^n_n$ are said to be idempotent. We show that $\mathcal{F}^n_1=\cdots =\mathcal{F}^n_{n-2}\subseteq\mathcal{F}^n_{n-1}\subseteq\mathcal{F}^n_n$ and we give conditions on the set $X$ for the last inclusions to be strict. The class $\mathcal{F}^n_1$ was recently characterized by Couceiro and Devillet \cite{CouDev}, who showed that its elements are reducible to binary associative operations. However, some elements of $\mathcal{F}^n_n$ are not reducible. In this paper, we characterize the class $\mathcal{F}^n_{n-1}\setminus\mathcal{F}^n_1$ and show that its elements are reducible. We give a full description of the corresponding reductions and show how each of them is built from a quasitrivial semigroup and an Abelian group whose exponent divides $n-1$. [less ▲]

Inclusive education has become a leading theme internationally over the past several decades, as it addresses key issues, often controversial, of exclusion/inclusion, learning opportunities, and educational equality and justice. Among international organizations as well as supranational governments, we find an increasing emphasis on recognizing diversity and enabling education for all. This is visible in the Salamanca Declaration (1994), the overall “education-for-all” agenda, the Sustainable Developments Goals (e.g., Education, SDG 4), and the worldwide ratification of the UN Convention on the Rights of People with Disabilities (e.g., Article 24 on Education), which mandates among state parties the establishment of an inclusive education system across levels, from early childhood to lifelong learning. This frame of reference is not only significant in terms of definitions and contents but also in the context of the strengthening of world society. The world societal level is not the same as what occurs in the relations between nation states, as important as such learning in policies and practices may be but extends beyond. This is evident in the definition of “inclusion” that has become significant internationally as a category signifying attempts to guarantee access and participation in different levels of education systems, but one that has contrasting and divergent understandings, implications, and implementation consequences between national and local contexts. The goal of participation that follows normatively and legally from such understandings of inclusion, is recontextualized differently, sometimes even paradoxically, when in fact segregated and separate settings are extended under the banner of inclusion. In Germany, for example, despite inclusion discourse flowing from such international agendas that focus on processes of integration and participation, the structures, cultures, and practices that disadvantage and disable continue to exist or even become strengthened. Even if the myriad dimensions of diversity are increasingly discussed and intersectional approaches become more important, the emphasis on difference of disability or “special educational needs” continues. In educational research, numerous publications have delineated the establishment of inclusive education from diverse perspectives. Over the past decade in particular, this has occurred in relation to the UN CRPD, which also implies a connection to the world society-frame; however, theorization and in-depth empirical analyses are lacking to explain more recent developments on multiple levels. Even for nation-states, few systematic and comparative studies have analyzed the diverse forms of inclusive education in different contexts. The consequence has been a divergence between the national discourses of inclusive education, for example, in the German-speaking countries, that remain focused on special educational needs, and the more global discourse that understands inclusive education in human rights terms and a key developmental process in democracies. Although some recent comparative research projects and dissertations provide insights into specific country contexts, a more comprehensive publication that collects such research results of international inclusive educational research has been lacking. Furthermore, the opportunity presents itself to extend the dialogue through a world society perspective on inclusion to reflect global inequalities via integrating case studies from the Global South. International and intercultural perspectives enable the investigation of structures, cultures and practices of different countries to the crucial comparison of educational processes. This is especially necessary in the case of inclusive education, whether as a source of inspiration, a reflexive critique of taken-for-grantedness or as a means to identify disparities and social inequalities. Thus, in several dozen chapters, the Handbook Inclusion International presents diverse global, national, and local perspectives on inclusive education. [less ▲]

The brain and peripheral bodily organs continuously exchange information. Exemplary, interoception refers to the processing and perception of ascending information from the body to the brain. Stress responses involve a neurobehavioral cascade, which includes the activation of peripheral organs via neural and endocrine pathways and can thus be seen as an example for descending information on the brain-body axis. Hence, the interaction of interoception and stress represents bi-directional communication on the brain-body axis. The main hypothesis underlying this review is that the dysregulation of brain-body communication represents an important mechanism for the generation of physical symptoms in stress-related disorders. The aims of this review are, therefore, (1.) to summarize current knowledge on acute stress effects on different stages of interoceptive signal processing, (2.) to discuss possible patterns of abnormal brainbody communication (i.e., alterations in interoception and physiological stress axes activation) in mental disorders and chronic physical conditions, and (3.) to consider possible approaches to modify interoception. Due to the regulatory feedback loops underlying brain-body communication, the modification of interoceptive processes (ascending signals) may, in turn, affect physiological stress axes activity (descending signals), and, ultimately, also physical symptoms.

This paper develops normative approaches for measuring individual-level income insecurity. Using concepts derived from Expected Utility Theory and Prospect Theory, we build a suite of measures designed to capture various facets of psychologically distressing income risk. We present an application for the US and Germany from 1993-2013, employing conditionally heteroskedastic fixed-effects models to generate predictive densities for future incomes. Our results reveal much higher levels of income risk in the US relative to Germany, which can be mostly attributed to a higher level of autonomous, time-invariant volatility. State-by-state variations in liberal/conservative political administrations partially explain our results, and we find some evidence that trade exposure is a contributing factor in the US. [less ▲]
