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 ▲]

We distinguish two general modes of testing for Deep Neural Networks (DNNs): Offline testing where DNNs are tested as individual units based on test datasets obtained without involving the DNNs under test, and online testing where DNNs are embedded into a specific application environment and tested in a closed-loop mode in interaction with the application environment. Typically, DNNs are subjected to both types of testing during their development life cycle where offline testing is applied immediately after DNN training and online testing follows after offline testing and once a DNN is deployed within a specific application environment. In this paper, we study the relationship between offline and online testing. Our goal is to determine how offline testing and online testing differ or complement one another and if offline testing results can be used to help reduce the cost of online testing? Though these questions are generally relevant to all autonomous systems, we study them in the context of automated driving systems where, as study subjects, we use DNNs automating end-to-end controls of steering functions of self-driving vehicles. Our results show that offline testing is less effective than online testing as many safety violations identified by online testing could not be identified by offline testing, while large prediction errors generated by offline testing always led to severe safety violations detectable by online testing. Further, we cannot exploit offline testing results to reduce the cost of online testing in practice since we are not able to identify specific situations where offline testing could be as accurate as online testing in identifying safety requirement violations.

Although French plural spelling has been studied extensively, the complexity of factors affecting the learning of French plural spelling are not yet fully explained, namely on the level of adjectival and verbal plural. This study investigates spelling profiles of French plural markers of 228 multilingual grade 5 pupils with French taught as a foreign language. Three analyses on the learner performances of plural spelling in nouns, verbs and pre- and postnominal attributive adjectives were conducted (1) to detect the pupils’ spelling profiles of plural marking on the basis of the performances in the pretest, (2) to test the profiles against two psycholinguistic theories, and (3) to evaluate the impact of the training on each spelling profile in the posttest. The first analysis confirms the existing literature that pupils’ learning of French plural is not random but ordered and emphasizes the role of the position for adjectives (pre- or postnominal) on correct plural spelling. The second analysis reveals the theoretical difficulties of predicting spelling of adjectival and verbal plural. The third analysis shows that strong and poor spellers both benefit from a morphosyntactic training and provides transparency and traceability of the learning trajectories. Together, the descriptive analyses reveal clear patterns of intra-individual spelling profiles. They point to a need for further research in those areas that have empirically provided the most inconsistent results to date and that are not supported by the theories: verbs and adjectives.

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 ▲]

This article provides an overview of existing community-contributed commands for executing event studies. 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 older command eventstudy provides a comfortable graphical user interface and good functionality for event studies that do not require hypotheses testing. The command estudy described in Pacicco et al. (2018, Stata Journal 18(2), pp. 416–476; 2020, Stata Journal, forthcoming) provides a set of commonly applied test statistics, useful exporting routines to spreadsheet software and LATEX for event studies with a limited number of events. The most complete command in terms of available test statistics and benchmark models as well as its ability to handle events with insufficient data, thin trading and large samples is eventstudy2 [less ▲]

It gives first a definition, global and European perspectives, before explaining case studies of Romanian women in Italian agriculture and victims of human trafficking in Sweden. The book chapter shows clearly that slavery and human trafficking are not only historical, but also recent phenomena. [less ▲]

We here consider the link between individual financial profiles over time and well-being, as measured by life satisfaction. We in particular look at annual self-reported financial worsening and improvement information for over 25,000 individuals in Australian panel data from 2002 to 2017. We first find that satisfaction falls (rises) with a contemporaneous major financial worsening (improvement), with the the largest correlation being with financial worsening. Second, the experience of these financial events in the past continues to be linked to current well-being. Last, only the order of financial-improvement spells relates to well-being: a given number of past years where finances deteriorated has the same association with current well-being whether the deterioration occurred in one continuous spell or was interrupted. We last show that these associations are heterogeneous over the distribution of well-being. [less ▲]

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.

We give a heuristic argument predicting that the number N*(T) of rationals p/q on Cantor’s middle thirds set C such that gcd(p, q) = 1 and q ≤ T, has asymptotic growth O(T^{d+ε}), for d = dim C. Our heuristic is related to similar heuristics and conjectures proposed by Fishman and Simmons. We also describe extensive numerical computations supporting this heuristic. Our heuristic predicts a similar asymptotic if C is replaced with any similar fractal with a description in terms of missing digits in a base expansion. Interest in the growth of N*(T) is motivated by a problem of Mahler on intrinsic Diophantine approximation on C. [less ▲]
