Methods Young healthy heterosexual couples underwent sleep-lab-based polysomnography of two sleeping arrangements: individual sleep and co-sleep. Individual and dyadic sleep parameters (i.e., synchronization of sleep stages) were collected. The latter were assessed using cross-recurrence quantification analysis. Additionally, subjective sleep quality, relationship characteristics, and chronotype were monitored. Data were analyzed comparing co-sleep vs. individual sleep. Interaction effects of the sleeping arrangement with gender, chronotype, or relationship characteristics were moreover tested. Results As compared to sleeping individually, co-sleeping was associated with about 10% (...) more REM sleep, less fragmented REM sleep (p = 0.008), longer undisturbed REM fragments (p = 0.0006), and more limb movements (p = 0.007). None of the other sleep stages was significantly altered. Social support interacted with sleeping arrangement in a way that individuals with suboptimal social support showed the biggest impact of the sleeping arrangement on REM sleep. Sleep architectures were more synchronized between partners during co-sleep (p = 0.005) even if wake phases were excluded (p = 0.022). Moreover, sleep architectures are significantly coupled across a lag of ± 5min. Depth of relationship represented an additional significant main effect regarding synchronization, reflecting a positive association between the two. Neither REM sleep nor synchronization was influenced by gender, chronotype, or other relationship characteristics. Conclusion Depending on the sleeping arrangement, couple's sleep architecture and synchronization show alterations that are modified by relationship characteristics. We discuss that these alterations could be part of a self-enhancing feedback loop of REM sleep and sociality and a mechanism through which sociality prevents mental illness. (shrink)

Until recently, cardiotoxicity in the setting of a malignant disease was attributed solely to the detrimental effects of chemo‐ and/or radio‐therapy to the heart. On this account, the focus was on the evaluation of well‐established cardiac biomarkers for the early detection of myocardial damage. Currently, this view has been revised. Cardiotoxicity is not restricted to a single organ but instead affects the endothelium as a whole. Indeed, it has come into light that not only cancer therapy but also malignant cells (...) per se can impair the cardiovascular system, through a paracrine and endocrine mode of action. Even more intriguingly, a clear interplay between molecular pathways involved in cancer and cardiovascular disease has become prevalent, suggesting a common nominator that governs the pathophysiology of these two entities. Taken together, our strategy in the quest of novel biomarkers in the emerging field of cardio‐oncology should be critically reshaped. (shrink)

This monograph evaluates public policy responses to the Covid-19 pandemic through a public choice lens. The book compares two prominent, albeit mutually exclusive, theories in social sciences—public interest theory and public choice theory—and explores how their predictions perform within the framework of the Covid-19 pandemic. The chapters present different pandemic policies alongside empirical data in order to draw conclusions about their efficacy, and, in turn, draw conclusions about the veracity of each theory. By the end of the volume, the reader (...) will be able to draw their own conclusions about whether the pandemic policy responses served the public interest, as public interest theory suggests, or the personal interests of the politicians who implemented them, as public choice theory holds.

The model of ownership psychology as a cognitive adaptation proposes that people flexibly navigate cognitive systems of cooperation and competition, thus enabling them to justify unethical behavior. We discuss how this model captures previous accounts of unethical behavior and propose that a disengagement heuristic can help us understand recent findings in the interconnection between scarcity psychology and unethical behavior.

White liberals like to claim that they live in a post-racial society. Furthermore, they believe that most people do not sympathize with the far-right. However, it is not racism fueling right-wing extremism in North America and Western Europe but the dominant ideology, liberalism. Consequently, Slavoj Žižek argues that racism is a problem concerning “objective violence,” which he further breaks down into “symbolic violence” and “systemic violence.” These primarily target minority groups. Thus, “objective violence” best explains the West’s problematic views of (...) Muslims and Islam since it supports what Edward Said refers to as “Orientalism” and reproduces racist depictions of racialized communities. These are incredibly harmful since the West still perceives the Orient and its residents as violent, strange, and backward. These Orientalist attitudes ultimately lead to discrimination against Muslims and Arabs. Furthermore, this ideology naturalizes and legitimizes capitalist social relations while concealing racialization processes. (shrink)

Immersive virtual reality (VR) emerges as a promising research and clinical tool. However, several studies suggest that VR induced adverse symptoms and effects (VRISE) may undermine the health and safety standards, and the reliability of the scientific results. In the current literature review, the technical reasons for the adverse symptomatology are investigated to provide suggestions and technological knowledge for the implementation of VR head-mounted display (HMD) systems in cognitive neuroscience. The technological systematic literature indicated features pertinent to display, sound, motion (...) tracking, navigation, ergonomic interactions, user experience, and computer’s hardware that should be considered by the researchers. Subsequently, a meta-analysis of 44 neuroscientific or neuropsychological studies involving VR HMD systems was performed. The meta-analysis of the VR studies demonstrated that the new generation HMDs induced significantly fewer dropouts and VRISE. Importantly, the commercial versions of the new generation HMDs with ergonomic interactions had zero incidents of adverse symptomatology and dropouts. Solely, HMDs equivalent to or greater than the commercial versions of contemporary HMDs accompanied with ergonomic interactions are suitable for implementation in cognitive neuroscience. In conclusion, researchers’ technological competency, along with meticulous methods and reports pertinent to software, hardware, and VRISE, are paramount to ensure the health and safety standards and the reliability of neuroscientific results.

The ontic conception of explanation is predicated on the proposition that “explanation is a relation between real objects in the world” and hence, according to this approach, scientific explanation cannot take place absent such a premise. Despite the fact that critics have emphasized several drawbacks of the ontic conception, as for example its inability to address the so-called “abstract explanations”, the debate is not settled and the ontic view can claim to capture cases of explanation that are non-abstract, such as (...) causal relations between events. However, by eliminating the distinction between abstract and non-abstract explanations, it follows that ontic and epistemic proposals can no longer contend to capture different cases of explanation and either all are captured by the ontic view or all are captured by the epistemic view. On closer inspection, it turns out that the ontic view deals with events that fall outside the scientists’ scope of observation and that it does not accommodate common instances of explanation such as explanations from false propositions and hence it cannot establish itself as the dominant philosophical stance with respect to explanation. On the contrary, the epistemic conception does account for almost all episodes of explanation and can be described as a relation between representations, whereby the explanans transmit information to the explanandum and that this information can come, dependent on context, in the form of any of the available theories of explanation (law-like, unificatory, causal and non-causal). The range of application of the ontic view thus is severely restricted to trivial cases of explanation that come through direct observation of the events involved in an explanation and explanation is to be mostly conceived epistemically.

Exploring both the intrapersonal (moral) and interpersonal (ethical) nature of death and dying in the context of their development (philosophical), Dying in a Transhumanist and Posthuman Society shows how death and dying have been and will continue to be governed in any given society. Drawing on transhumanism and discourses about posthumanity, life prolongation and digital life, the book analyses death, dying and grief via the governance of dying. It states that the bio-medical dimensions of our understanding of death and dying (...) have predominated not only the discourses about death in society and the care of the dying, but their policy and practice as well. It seeks to provoke thinking beyond the benefits of technology and within the confinements of the world transhumanists describe. This book is written for all who have an interest in thanatology (i.e. death studies) but will be useful specifically to those investigating the experiences of dying and grieving in contemporary societies, wherein technology, biology and medicine continuously advance. Thus, the manuscript will be of interest to researchers in a broad range of areas including health and social care, social policy, anthropology, sociology, philosophy, cultural studies, and, of course, thanatology.

Different why-questions emerge under different contexts and require different information in order to be addressed. Hence a relevance relation can hardly be invariant across contexts. However, what is indeed common under any possible context is that all explananda require scientific information in order to be explained. So no scientific information is in principle explanatorily irrelevant, it only becomes so under certain contexts. In view of this, scientific thought experiments can offer explanations, should we analyze their representational strategies. Their representations involve (...) empirical as well as hypothetical statements. I call this the “representational mingling” which bears scientific information that can explain events. Buchanan’s thought experiment from constitutional economics is examined to show how mingled representations explain. (shrink)

This article is divided into two parts: in the first we explore the academic debate conducted at an international level about insider trading (IT). In particular, we exame IT on three grounds: economic, ethical and legal. In each section we present the arguments in favour of and against IT and then we give our personal opinion. In the second part we present the situation in the Athens Stock Exchange. We examine its past record on the issue of IT and recent (...) developments, and comment on the implications for the future.

We present various results regarding the decidability of certain sets of sentences by Simple Type Theory. First, we introduce the notion of decreasing sentence, and prove that the set of decreasing sentences is undecidable by Simple Type Theory with infinitely many zero-type elements ; a result that follows directly from the fact that every sentence is equivalent to a decreasing sentence. We then establish two different positive decidability results for a weak subtheory of math formula. Namely, the decidability of math (...) formula and math formula. Finally, we present some consequences for the set of existential-universal sentences. All the above results have direct implications for Quine's theory of “New Foundations” and its weak subtheory math formula. (shrink)

The paper examines more broadly the intellectual formation, early carreer and research activity of Franz Dölger with the aim to elucidate, on the one hand, the shift that took place in Byzantine Studies in Munich during the Thirties of the previous century from a philological to a historical direction. On the other hand, the paper offers a detailed analysis of Dölger’s concept of Byzantine literature and its history, the development of this concept and its immediate impact on Byzantine Philology as (...) a separate field within Byzantine Studies. Pivotal in understanding Dölger’s concept are his connection with and use of the Nazi regime and its ideology, as well as a latent but visible antagonism to Karl Krumbacher. The paper includes an analysis of hitherto unknown publications of Dölger from the Nazi era and a number of unpublished documents pertaining to the Athos Expedition of July 1941 and its aftermath.

Neuroplasticity, the capacity of the brain to induce changes in response to environmental stimuli, entails a continuous rearrangement of the neural network through a complex interaction between genetics and environment. Within this process, the plastic brain uses its internal representations to predict future conditions and proactively proceed to actions. It can be said that plasticity demands a rethinking of the concept of determinism as the process of coming-to-be is directly related to modifications produced by experience. Pure determinism and complete randomness (...) are the two ends of a spectrum of positions relevant to the debate of the existence of free will. However, none conceptually supports free decision-making. How brain activity and the conscious experience of volition are related to one another has been a matter of significant research, with a plethora of findings indicating that early brain signals precede the self-reported time of the decision to act. The meaning of these findings, however, has been debated at both a theoretical and empirical level and the controversy is still ongoing. Consciousness is intertwined with free will along the dimension of time as it would otherwise be purposeless, taking place right at the next moment. Electrical activity of the brain is a measure of neurophysiological function and contributes to the understanding of processes that underlie high-order cognitive functions. A multidisciplinary approach in the study of free will could be designed in a way that philosophical concepts are connected to neural correlates by psychologically functionalizing them in terms of cognitive abilities. Such abilities are at the margins of conscious and nonconscious sensory information and are closely linked to brain processes of executive functions like attentional control and working memory.

COVID-19 is not only a health emergency but also a strategic challenge for any politics of resistance, struggle and transformation. Understanding the social and political dynamics associated with morbidity and mortality and the many ‘ecologies of disease’ associated with the pandemic is necessary if we want to think beyond the limits of the lockdown strategy. It is here that the possibility of a democratic biopolitics emerges as part of a broader strategy for communism.

In A Philosophy for Communism: Rethinking Althusser Panagiotis Sotiris attempts a reading of the work of the French philosopher centered upon his deeply political conception of philosophy. Althusser's endeavour is presented as a quest for a new practice of philosophy that would enable a new practice of politics for communism, in opposition to idealism and teleology. The central point is that in his trajectory from the crucial interventions of the 1960s to the texts on aleatory materialism, Althusser remained a (...) communist in philosophy. This is based upon a reading of the tensions and dynamics running through Althusser's work and his dialogue with other thinkers. Particular attention is paid to crucial texts by Althusser that remained unpublished until relatively recently. (shrink)

Events regarding individuals’ preferences that do not always follow from standard measures such as “value of statistical life” or “quality-adjusted life years” as well as events that occur in some market-related settings which distort the information conveyed by price mechanisms, suggest that a notable chunk of what Hayek called “local knowledge” remains inaccessible by scientific tools and that only the individuals who interact in these local frameworks can have access to it. This casts serious doubt on the epistemic possibility of (...) economic calculation for if events in the local world do not observe the economic models, it is hard to see how central planners can have knowledge on them. Refined modeling strategies and cutting-edge Artificial Intelligence systems do not manage to overcome this hurdle. They may provide huge datasets in a data model, but since not all events represented in the data model are embeddable in known economic models, the knowledge problem is not evaded. Even if a theory ever manages to capture all possible events as they appear in the data model then we are left with a relationship between models (the theoretical model and the data model) with no direct access to the local world and thus the problem of accessibility of local knowledge remains unresolved.

Tangled Type Theory was introduced by Randall Holmes in [3] as a new way of approaching the consistency problem for$\mathrm {NF}$. Although the task of finding models for this theory is far from trivial (considering it is equiconsistent with$\mathrm {NF}$), ways of constructing models for certain fragments of it have been discovered. In this article, we present a simpler way of constructing models of predicative Tangled Type Theory and consequently of predicative$\mathrm {NF}$. In these new models of predicative$\mathrm {NF}$, the (...) universe is well-orderable and equinumerous to the set of singletons. (shrink)

Do psychological perspectives constitute the only way through which the role of musical creativity in education can be addressed, researched and theorised? This essay attempts to offer an alternative view of musical creativity as a deeply social and political form of human praxis, by proposing a perspective rooted in the thought of the political philosopher and activist Cornelius Castoriadis (1922–1997). This is done in two steps. First, an attempt is made to place the pursuit of the concept of musical creativity (...) within a larger educational and societal context of conflicting trajectories that run through (a) Modernity and (b) Education. Then, I revisit the issue of educational value of improvising and composing through creating conceptual links between the process of music-making through improvisation and composition and the project of political autonomy as conceived by Castoriadis. By foregrounding instituting imaginary over instituted imaginary, improvising and composing become active processes of positing new legitimacies, and of creating a music-making context that searches for its own foundations. It is in and through creative musical praxis that we can think about issues of hierarchies, musical values, social dimensions of different music-making processes, our relationship to past values and to historical dimensions of music. By arguing that improvisation and composition might be seen as ways of positing the issue of political autonomy in musical terms, this paper emphasises the role of improvisation and composition as a mode of potentially transformative educational practice that may foster the development of critical consciousness, linking music education to a larger project of re-discovering and at the same time re-defining democracy.

Against the traditional interpretation of Doxa as intrinsically and thoroughly deceiving and untrustworthy, the present essay examines the passages which follow the self-characterization of the goddess’ speech as ‘deceitful.’ The traits of an extensive cosmogony and cosmology open up the possibility for discerning two aspects of Doxa: first a presentation of mortal erroneous opinions, but then also their correction within the framework of the ‘appropriate world-arrangement’ presented by the goddess.
