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.

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.

The end of the Second World War was the start of a new era, with worldwide support for a Universal Declaration of Human Rights (UDHR). As a UN organisation, UNESCO was assigned to present the UDHR towards the global population in an effort to guide them to peace. In 1949, their Department of Mass Communication created three tools to promote human rights: a large-scale exhibition at the Musée Galliera in Paris, a travel album, and teaching handbooks. In my chapter, I will focus on the travel album, and in particular, on article 26: “The Right to Education”. As in the album, the right is represented by a number of images and captions, all related to this article of the UDHR. I will analyse the visuals and the corresponding texts from an intermediate perspective. Does the narrative created by UNESCO actually relate to the meaning of the pictures? Then, I will analyse the global correspondence received on the travel album. How did the viewers understand the album and was it as comprehensible as UNESCO thought? This chapter argues that the promotion and mediation of human rights were based on Western standards of education, making it difficult to spread a universal message. [less ▲]

ABSTRACT This study sheds light on agency conflicts between creditors and shareholders and their effect on a firm's corporate social responsibility (CSR) performance. We find that the presence of institutional investors which simultaneously hold debt and equity claims in the same firm, so-called dual holders, leads to an increase in CSR performance by the firm that is dual-held (the dual holding firm). Using institutional mergers between separate lenders and equity holders as a natural experiment involving the shareholder-creditor conflict, we find that firms which exhibit dual ownership for the first time increase their CSR activities to a greater extent than a matched control group. In line with the previous literature, we interpret our findings as evidence that dual holders internalise agency conflicts. Thus, we find that a reduction in agency conflicts between creditors and shareholders, partly achieved by dual holders, positively affects the CSR activities of dual holdings. [less ▲]

I assess which command(s) could have been used to conduct event studies that have appeared in the past ten years in three leading accounting, finance and management journals.

The command estudy described in Pacicco et al.

The ability to monitor internal bodily and cognitive processes is essential for everyday functioning and independence in older adults, because it allows for adjustments when lapses in performance are imminent. In the present study, age-related morphological changes to the heartbeat evoked potential (HEP), an electrophysiological cortical representation of cardiac signals, and its association with self-reported everyday cognition were examined. A community sample of older adults showed an increased HEP amplitude, which could reflect a stronger representation of early stages of cardiac interoception, and a more anterior scalp distribution of the HEP, suggesting a more widespread configuration of the underlying neural generators, compared to a group of young adults. Furthermore, in older adults, HEP amplitude was negatively correlated with self-estimated everyday cognitive functioning. Older adults with pronounced cortical representations of peripheral signals may thus be more likely to take note of lapses in their own bodily and cognitive function, leading to lower estimates of their cognitive abilities. These results provide novel insights into age-related changes in interoceptive processing and their association with metacognitive judgments, with potentially far-reaching implications for cognitive aging and age-related cognitive decline.

In diesem Handbuch wird das Augenmerk auf globale, regionale und lokale Fragestellungen Inklusiver Bildung gerichtet. Inklusive Bildung kann dabei als weltweites Paradigma bezeichnet werden, mit dem Teilhabe und Partizipation sowie Prozesse des Ein- und Ausschlusses in Bildungskontexten und darin eingelagerte Barrieren sowie Diskriminierungen in den Blick genommen werden. Politisch-normative Setzungen Inklusiver Bildung – u.a. durch die UN-Behindertenrechtskonvention (UN-BRK) (UN 2006) – werden derzeit in bildungspolitischer Hinsicht national, regional und lokal aufgegriffen und daran anschließend Prozesse der Steuerung in Bildungssystemen initiiert. Inklusion kann dabei als "fuzzy concept" (Artiles/Dyson 2005: 43) beschrieben werden, das sich dadurch auszeichnet, dass es auf nationaler und regionaler Ebene in differenten historisch entwickelten, kulturell ausgeprägten sowie normativ und rechtlich fundierten Bil- dungssystemen aufgenommen und in die Praxis übersetzt bzw. transformiert werden muss. In den deutschsprachigen Bildungs- und Erziehungswissenschaften ist Inklusive Bildung zu einem interdisziplinären Leitbegriff avanciert, der insbesondere in der Schulpädagogik, der Sonderpädagogik und der Allgemeinen Erziehungswissenschaft diskutiert wird, allerdings auch hier mit unterschiedlichen Vorstellungen. Trotz globaler Relevanz stellen internationale und komparative Fragestellungen im Kontext Inklusiver Bildung bislang im deutschsprachigen wie internationalen Diskurs ein unzureichend bearbeitetes Forschungsfeld dar – insbesondere mit Blick auf international und interkulturell vergleichende Forschungsarbeiten. Vor diesem Hintergrund sind in diesem Handbuch Beiträge versammelt, die das Feld der internationalen, interkulturellen und komparativen Forschung schärfen und Inklusive Bildung – anschließend an die Diskurslinien der Disability Studies – als Prozess der Beseitigung von Barrieren und Benachteiligungen in Bildungssystemen und -organisationen verstehen. Dementsprechend werden Prozesse der Exklusion und Aussonderung sowie der Unterstützung und Inklusion mit besonderer Berücksichtigung komparativer Perspektiven analysiert, wobei unterschiedliche Dimensionen von Heterogenität und deren Intersektionalität, insbesondere mit Blick auf marginalisierte und von Exklusion bedrohter Personengruppen, berücksichtigt werden. Aufgrund der disziplinären Verortung der Autor*innen – v.a. in der Erziehungswissenschaft und Soziologie – und deren Beschäftigung mit Behinderungen und Benachteiligungen, rückt die Differenzlinie Behinderung bzw. „behindert werden“ in den Vordergrund.

This study examines how coal companies were affected by the announcement of thermal coal divestment made by Blackrock, a large institutional asset manager. Following the announcement, the largest thermal coal mining companies exhibited negative abnormal returns. However, the stock prices of other firms were not affected. Blackrock’s own share price increased following the announcement. We provide additional evidence that Blackrock protected its clients by lowering its exposure towards affected companies before the announcement. Overall, our results show that divestment has significant impacts on the companies in question and that the capital market sees divestment as value-enhancing for the divesting institution. [less ▲]

We study optimal policy experimentation by a committee. We consider a dynamic bargaining game in which committee members choose either a risky reform or a safe alternative each period. When no redistribution is allowed the unique equilibrium outcome is generically inefficient. When redistribution is allowed (even small amounts), there always exists an equilibrium that supports optimal experimentation for any voting rule without veto players. With veto players, however, optimal policy experimentation is possible only with a sufficient amount of redistribution. We conclude that veto rights are more of an obstacle to optimal policy experimentation than the constraints on redistribution themselves. [less ▲]

We consider the effects of major prenatal economic shocks experienced by mothers on two indicators of newborn-infant health, birth weight and head circumference, using detailed microdata from the UK ALSPAC survey. Controlling for physiological and socioeconomic factors, an economic shock in the first 18 weeks of gestation lowers birth weight by 40-70 grams and head circumference by 2-3mm. We find evidence of transmission via poorer maternal health due to absolute material deprivation and tobacco and alcohol consumption, but not for the endocrinological effects of increased psychosocial anxiety. The fragile-male hypothesis holds for birth weight but not for head circumference, as predicted by recent theories on gender differences in prenatal development. [less ▲]

We examine some ordinal measures of inequality that are familiar from the literature. These measures have a quite simple structure in that their values are determined by combinations of specific summary statistics such as the extreme values and the arithmetic mean of a distribution. In spite of their common appearance, there seem to be no axiomatizations available so far, and this paper is intended to fill that gap. In particular, we consider the absolute and relative variants of the range; the max-mean and the mean-min orderings; and quantile-based measures. In addition, we provide some empirical observations that are intended to illustrate that, although these orderings are straightforward to define, some of them display a surprisingly high correlation with alternative (more complex) measures.

In this paper, we propose a novel energy-efficient framework for an electric vehicle (EV) network using a contract theoretic-based economic model to maximize the profits of charging stations (CSs) and improve the social welfare of the network. Specifically, we first introduce CS-based and CS clustering-based decentralized federated energy learning (DFEL) approaches which enable the CSs to train their own energy transactions locally to predict energy demands. In this way, each CS can exchange its learned model with other CSs to improve prediction accuracy without revealing actual datasets and reduce communication overhead among the CSs. Based on the energy demand prediction, we then design a multi-principal one-agent (MPOA) contract-based method. In particular, we formulate the CSs' utility maximization as a non-collaborative energy contract problem in which each CS maximizes its utility under common constraints from the smart grid provider (SGP) and other CSs' contracts. Then, we prove the existence of an equilibrium contract solution for all the CSs and develop an iterative algorithm at the SGP to find the equilibrium. Through simulation results using the dataset of CSs' transactions in Dundee city, the United Kingdom between 2017 and 2018, we demonstrate that our proposed method can achieve the energy demand prediction accuracy improvement up to 24.63% and lessen communication overhead by 96.3% compared with other machine learning algorithms. Furthermore, our proposed method can outperform non-contract-based economic models by 35% and 36% in terms of the CSs' utilities and social welfare of the network, respectively. [less ▲]
