Primary headaches are highly prevalent and represent a major cause of disability in young adults. Neurofeedback is increasingly used in the treatment of chronic pain; however, there are few studies investigating its efficacy in patients with headaches. We report the results of a cross-over sham-controlled study on the efficacy of neurofeedback in the prophylactic treatment of tension-type headache. Participants received ten sessions of infra-low frequency electroencephalographic neurofeedback and ten sessions of sham-neurofeedback, with the order of treatments being randomized. The study (...) also included a basic psychotherapeutic intervention — a psychoeducational session performed before the main study phases and emotional support provided throughout the study period. The headache probability was modeled as a function of the neurofeedback and sham-neurofeedback sessions performed to date. As a result, we revealed a strong beneficial effect of neurofeedback and no influence of the sham sessions. The study supports the prophylactic use of infra-low frequency neurofeedback in patients with TTH. From a methodological point of view, we advocate for the explicit inclusion of psychotherapeutic components in neurofeedback study protocols. (shrink)

Aging is associated with decreased functional connectivity in the main brain networks, which can underlie changes in cognitive and emotional processing. Neurofeedback is a promising non-pharmacological approach for the enhancement of brain connectivity. Previously, we showed that a single session of infra-low frequency neurofeedback results in increased connectivity between sensory processing networks in healthy young adults. In the current pilot study, we aimed to evaluate the possibility of enhancing brain connectivity during aging with the use of infra-low frequency neurofeedback. Nine (...) females aged 52 ± 7 years with subclinical signs of emotional dysregulation, including anxiety, mild depression, and somatoform symptoms, underwent 15 sessions of training. A resting-state functional MRI scan was acquired before and after the training. A hypothesis-free intrinsic connectivity analysis showed increased connectivity in regions in the bilateral temporal fusiform cortex, right supplementary motor area, left amygdala, left temporal pole, and cerebellum. Next, a seed-to-voxel analysis for the revealed regions was performed using the post- vs. pre-neurofeedback contrast. Finally, to explore the whole network of neurofeedback-related connectivity changes, the regions revealed by the intrinsic connectivity and seed-to-voxel analyses were entered into a network-based statistical analysis. An extended network was revealed, including the temporal and occipital fusiform cortex, multiple areas from the visual cortex, the right posterior superior temporal sulcus, the amygdala, the temporal poles, the superior parietal lobule, and the supplementary motor cortex. Clinically, decreases in alexithymia, depression, and anxiety levels were observed. Thus, infra-low frequency neurofeedback appears to be a promising method for enhancing brain connectivity during aging, and subsequent sham-controlled studies utilizing larger samples are feasible.

Defining the degree of categoricity of a computable structure ${\mathcal{M}}$ to be the least degree d for which ${\mathcal{M}}$ is d-computably categorical, we investigate which Turing degrees can be realized as degrees of categoricity. We show that for all n, degrees d.c.e. in and above 0 (n) can be so realized, as can the degree 0 (ω).

The paper explores the contextualist approach towards the semantics of knowledge ascriptions. The authors discuss the relevance of these studies in semantics for the major issues in virtue epistemology. It is argued that despite the advantages that contextualism has over its alternatives (in particular, relativism and subject sensitive invariablisism), it still requires a more elaborated compositional semantics that it currently has. We review several concrete contextualsit proposals to the semantics of the verb know in light of their applicability to the (...) well-known type of examples known as the fake barn example, point out some of their particular shortcomings, and propose a revision, which represents a variant of D. Lewis’s general approach to the semantics of know. (shrink)

We investigate the complexity of embeddings between bi-embeddable structures. In analogy with categoricity spectra, we define the bi-embeddable categoricity spectrum of a structure A as the family of Turing degrees that compute embeddings between any computable bi-embeddable copies of A; the degree of bi-embeddable categoricity of A is the least degree in this spectrum (if it exists). We extend many known results about categoricity spectra to the case of bi-embeddability. In particular, we exhibit structures without degree of bi-embeddable categoricity, and (...) we show that every degree d.c.e above 0(α) for α a computable successor ordinal and 0(λ) for λ a computable limit ordinal is a degree of bi-embeddable categoricity. We also give examples of families of degrees that are not bi-embeddable categoricity spectra. (shrink)

D. Barton Johnson traces the parallel lives and literary origins of two Russo-American writers: Ayn Rand and Vladimir Nabokov. Born in Saint Peterburg six years apart, they overlapped on the New York Times bestsellers list in the late fifties. While Nabokov's Russian cultural roots have been much explored, Rand's were little realized prior to Chris Matthew Sciabarra's investigation of her Russian philosophical context. Nabokov and Rand represent polar examples of their cultural heritage: for Nabokov, the aesthetically-oriented tradition of the modernist (...) Russian Symbolists; for Rand, the social-utilitarian tradition of Nikolai Chernyshevsky, and later, Maxim Gorky, founder of Socialist Realism. (shrink)

The quest for the one "Truth" in a pluralist society seems to have become as redundant as it is problematic - in much the same way that the idea of one "God" being the all-determining reality has. Yet we have not given up searching and the word "God" still continues to polarize, whether in society, theology or philosophy. In view of this seeming paradox, Friederike D. Rass seeks an alternative route that goes off the beaten track and beyond the temptation (...) to resignedly retreat to relativist or fundamentalist positions. She argues that it is precisely the supposedly futile quest for a single "Truth" as well as the continuous questioning of the meaning of the word "God" that provide an essential guide to responsible action today.

Sanskrit text with commentaries on the theories of error in Mīmāṃsa school in Hindu philosophy by Maṇḍanamiśra, 7th century philosopher.

John Kinsella’s poetry returns again and again to the landscape of the Western Australian wheatbelt. The wheatbelt is a region that was suddenly and violently re-made by capital in the service of cereal and fibre production during the course of the twentieth century. Despite this radical repurposing of land and the wholesale eradication of an ancient biome, the new farming zone quickly took on the halo of a natural landscape within state and nationalist ideologies. Against the backdrop of this event, (...) Kinsella’s wheatbelt can be viewed as a comprehensive deconstruction of the forces that have led the wheatbelt to where it is now and which still provide the material conditions of its existence. In this essay, Kinsella’s Divine Comedy: Journeys Through a Regional Geography is considered as exemplary of his wheatbelt poetry. The essay explores the basic conceits that animate Kinsella’s poetics of critique. It argues that Kinsella’s poetry offers a strategic intervention into the claims of “capitalist realism,” which is Mark Fisher’s term for the foreclosure of alternatives to profit-driven patterns of production and consumption. Capitalist realism, in the context of the wheatbelt, asserts that whether we like it or not, one cannot argue against the basic entitlement that productive imperatives have to use land as they see fit. This essay attempts to detail the kinds of ways that Kinsella’s poetry tries to fracture this claim to common sense that capitalist production monopolises. What it finds, somewhat counter-intuitively, is that Kinsella’s poetry draws together two things which are traditionally regarded as antinomies – the machine and the organism. In this respect, Kinsella’s poetry is distinctly different from conventional ecopoetry, which tends to uphold the distinction between an authentic nature and a corrupting technology. Kinsella’s Divine Comedy makes use of the tripartite layering of Dante’s eschatology to evolve new topologies of being in the wheatbelt, and indeed, being in the world. Further still, the essay makes the claim that Kinsella delivers us a “cybernetic wheatbelt,” which refigures nature as a communicative machine. (shrink)

During the nineteen years of her play-writing career, Aphra Behn had far more new plays staged than anyone else. This book is the first to examine all her theatrical work. It explains her often dominant place in the complex theatrical culture of Charles II's reign, her divided political sympathies, and her interests as a free-thinking intellectual. It also reveals her as a brilliant theatrical practitioner, who used the seen as richly and significantly as the spoken.

Focusing on the case of Comet Systems Inc. and its data gathering practices, this paper explores the technical details of gathering personal information in databases in general and the special character of the privacy issue raised by 'anonymous' information about individual behavior on the Internet. The case analysis suggests new insights for our understanding of privacy and frames a discussion of policy alternatives with respect to (...) the privacy of Internet communication. (shrink)

In the last decades of the XXth century we have witnessed a still growing interest in applied ethics, among them also bioethics, which in Slovak ethical literature was paid only a little attention as yet. The paper tries to examine the needs that led to the rise of bioethics, analyzing at the same time the concept of bioethics, its substance and subject. It deals also with its sources, putting stress on utilitarist and deontological ethics.

Open peer commentary on the article “The Autopoiesis of Social Systems and its Criticisms” by Hugo Cadenas & Marcelo Arnold. Upshot: Autopoiesis based on meaning is a rich conceptual tool. It would be a pity to reduce it to a few general statements on self-reference in social systems.

The article examines the nature of the dogmatics found in the poetry written by Gregory of Nazianzus through a particular case-study, the poem On the Son. It demonstrates that his lyric composition contains the same doctrine conveyed by the orations authored by him and exposes the manner in which he employs similar terminology in works belonging to both genres. In order to attain its objective my article compares the above-mentioned piece with Orations 29 and 30 that bear the same title.
