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)

In his 2011 article “Global Bifurcation: The Decision Window” Ervin Laszlo notes that “we have reached a watershed in our social and cultural evolution. The sciences of systems tell us that when complex open systems … approach a condition of critical instability, they face a moment of truth: they either transform or break down.” In this article we provide our own vision of this Global Bifurcation. This work stems naturally from the research highlighted in the article titled “Transition to Crisis-Free (...) Development: A Myth or Reality?” that was published in World Futures in 2014. In our new article, we move forward suggesting that crises-free development is not only possible but is also very likely, and paradoxically the world is now going through the most challenging transition from one paradigm of development to another. Based on our previous research as well as the findings of the Fifth Report to the Club of Rome, we suggest reasons for the development and implementation of a megaproject featuring a new model of life so as to make the paradigm shift possible, exclude negative implications of the upcoming technological “singularity,” and foster the achievement of an objectively defined goal of development, and this should reasonably require support from and direct involvement of the United Nations. The mechanism for implementation of this model suggests coordinating interests of the government, society, and business communities on each level with interests of particular individuals. (shrink)

Objective: Fertility loss due to cancer treatment can be a devastating experience for women and the couple. Undergoing fertility preservation can be a complex decision from both a medical and emotional point of view. The aim of the present study was to evaluate which socio-demographic and psychological factors predict a high motivation to undergo fertility preservation.Methods: Fifty-eight female cancer patients who accessed an Oncofertility Unit completed: a questionnaire to collect socio-demographic characteristics and the level of motivation, the Beck-Depression Inventory-II, the (...) State-Trait Anxiety Inventory-Y, and the Fertility Problem Inventory.Results: Almost half of the sample declared a high motivation. At multiple logistic regression analysis only the “Need for parenthood” subscale of the FPI predicted a high motivation. We alternatively evaluated as possible predictor the construct “Representations about the importance of parenthood” in place of the two separate subscales. At multiple logistic regression analysis, only this variable predicted a high motivation to undergo fertility preservation.Conclusion: The most important predictor of a high motivation to undergo fertility preservation is the individual desire for parenthood. This implies that, regardless of socio-demographic characteristics, any woman of childbearing age should receive an appropriate counseling about fertility preservation. (shrink)

Cohesive powersof computable structures are effective analogs of ultrapowers, where cohesive sets play the role of ultrafilters. Let$\omega $,$\zeta $, and$\eta $denote the respective order-types of the natural numbers, the integers, and the rationals when thought of as linear orders. We investigate the cohesive powers of computable linear orders, with special emphasis on computable copies of$\omega $. If$\mathcal {L}$is a computable copy of$\omega $that is computably isomorphic to the usual presentation of$\omega $, then every cohesive power of$\mathcal {L}$has order-type$\omega + (...) \zeta \eta $. However, there are computable copies of$\omega $, necessarily not computably isomorphic to the usual presentation, having cohesive powers not elementarily equivalent to$\omega + \zeta \eta $. For example, we show that there is a computable copy of$\omega $with a cohesive power of order-type$\omega + \eta $. Our most general result is that if$X \subseteq \mathbb {N} \setminus \{0\}$is a Boolean combination of$\Sigma _2$sets, thought of as a set of finite order-types, then there is a computable copy of$\omega $with a cohesive power of order-type$\omega + \boldsymbol {\sigma }(X \cup \{\omega + \zeta \eta + \omega ^*\})$, where$\boldsymbol {\sigma }(X \cup \{\omega + \zeta \eta + \omega ^*\})$denotes the shuffle of the order-types inXand the order-type$\omega + \zeta \eta + \omega ^*$. Furthermore, ifXis finite and non-empty, then there is a computable copy of$\omega $with a cohesive power of order-type$\omega + \boldsymbol {\sigma }(X)$. (shrink)

En este artículo se resaltan las semejanzas entre el teatro griego de los siglos V y IV A.C, y los aspectos dramáticos de la Apología de Sócrates y el Banquete de Platón, argumentando a favor del carácter filosófico de aspectos como la puesta en escena y el manejo de los personajes. Parahacerlo se replantea la relación entre la obra de Platón y la de los poetas, cambiando el foco de atención de su famosa censura a las representaciones teatrales, para iluminar (...) su empleo de mecanismos dramatúrgicos articulados con planteamientos éticos y políticos. Se concluye que Platón utiliza recursos del teatro griego, pero los extrapola y los transforma creando un nuevo tipo de drama. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:“Though This Be Madness, Yet There Is Method in ’T”A Positive Account of MadnessValentina Cardella, PhD (bio)What does it mean to be mad? How can we define mental disorder? The question is still widely discussed among psychiatrists and philosophers, and what exactly distinguishes sanity and insanity remains unclear. Despite this lack of clarity, the common conceptualization of madness is that mental disorders are impairments in rationality: people with mental (...) disorders are generally believed to have impairments in reasoning and logic (Bermúdez, 2001; Edwards, 1981; Harvey, Watkins, Mansell, & Shafran, 2004).Yet, the result of this conception is that we fail to understand madness. We do not understand how, for example, schizophrenic patients can be more logical than healthy people in some reasoning tasks (Mellet et al., 2006; Owen, Cutting, & David, 2007), or delusional patients can be perfectly rational in defending their ideas (Cardella, 2020), or depressive people can be more realistic than non-clinical subjects (Moore & Fresco, 2012). In contrast, if we consider rationality as the core feature of sanity, we fail to understand sanity, too, because normal people exhibit many kinds of biases and heuristics, and thus irrationality is widespread in the general population (Bortolotti, 2020; Johnson-Laird, 2006; Evans, 2002; Kahneman, Tversky, & Slovic, 1982).In his paper, Garson focuses on Late Modern theorists of madness (Locke, Kant, Wigan, and Heinroth) to reframe the problem and provide a positive account of mental disorder. These authors contrast madness to idiocy, rather than sanity, and therefore their conception of madness is very different: “while idiocy is marked by the diminished, or even abolished, functioning of the reasoning power, madness is marked by its perverse functioning. The mad person “has” reason, but deploys it in a perverse, improper, or unseemly manner” (Garson, 2023, p. 286).In his reading of Late Modern authors, Garson provides a new ontology of mental disorder, that goes beyond an absence of reason, and has also political and social implications. Furthermore, he reminds us that every scientific discipline has its philosophical assumptions. In defining madness, [End Page 305] we cannot help but choose a contrasting class, and each choice will have very different consequences. Even if psychiatry is a medical discipline, which aims to endorse a neutral view of mental disorder, it is impossible for it to be unbiased and impartial. All the more so, for it has to deal with human suffering and fragility.But, in this article, there is one crucial question that remains unanswered. In his analysis of Late Modern theorization of madness, Garson comes to the conclusion that madness is marked by a perverse deployment of reason. Yet, who decides when reason is deployed in a perverse manner? While the lack of rationality is something that we can detect easily enough, the task of defining precisely what is an ‘improper’ or ‘perverse’ use of reason is much harder. In other words, it seems to me that, in replacing the ‘lack of rationality’ paradigm with ‘the perverse rationality paradigm,’ the question of what is madness still remains open, and, most important, some normative aspects remain necessary.

В работе ставится вопрос о роли изобразительного начала в абстрактном искусстве Франции периода после Второй мировой войны. Рассматривая творчество и теоретические суждения ведущих мастеров пейзажной абстракции, ташизма, оп-арта, автор приходит к заключению, что принцип мимесиса был не исключен из их искусства, но переосмыслен: задача правдоподобного воссоздания зримых форм сменилась поиском способов обобщенной передачи процессов и структур внешнего мира. Творчество таких мастеров, как Альберто Джакометти и Никола де Сталь, «вырастивших» фигуративные формы из нефигуративных, показывает, что между двумя системами нет непроходимой границы, (...) но существует множество переходных стадий. Заключительная глава посвящена направлению повествовательной фигуративности и роли абстрагирующих моделей реальности в нем. (shrink)

v. 1. Commentaria in Aristotelem Armeniaca-Davidis Opera.

Lists of species underpin many fields of human endeavour, but there are currently no universally accepted principles for deciding which biological species should be accepted when there are alternative taxonomic treatments (and, by extension, which scientific names should be applied to those species). As improvements in information technology make it easier to communicate, access, and aggregate biodiversity information, there is a need for a framework that helps taxonomists and the users of taxonomy decide which taxa and names should be used (...) by society whilst continuing to encourage taxonomic research that leads to new species discoveries, new knowledge of species relationships, and the refinement of existing species concepts. Here, we present 10 principles that can underpin such a governance framework, namely (i) the species list must be based on science and free from nontaxonomic considerations and interference, (ii) governance of the species list must aim for community support and use, (iii) all decisions about list composition must be transparent, (iv) the governance of validated lists of species is separate from the governance of the names of taxa, (v) governance of lists of accepted species must not constrain academic freedom, (vi) the set of criteria considered sufficient to recognise species boundaries may appropriately vary between different taxonomic groups but should be consistent when possible, (vii) a global list must balance conflicting needs for currency and stability by having archived versions, (viii) contributors need appropriate recognition, (ix) list content should be traceable, and (x) a global listing process needs both to encompass global diversity and to accommodate local knowledge of that diversity. We conclude by outlining issues that must be resolved if such a system of taxonomic list governance and a unified list of accepted scientific names generated are to be universally adopted. (shrink)

Vocal bursts are non-linguistic affectively-laden sounds with a crucial function in human communication, yet their affective structure is still debated. Studies showed that ratings of valence and arousal follow a V-shaped relationship in several kinds of stimuli: high arousal ratings are more likely to go on a par with very negative or very positive valence. Across two studies, we asked participants to listen to 1,008 vocal bursts and judge both how they felt when listening to the sound (i.e. core affect (...) condition), and how the speaker felt when producing it (i.e. perception of affective quality condition). We show that a V-shaped fit outperforms a linear model in explaining the valence-arousal relationship across conditions and studies, even after equating the number of exemplars across emotion categories. Also, although subjective experience can be significantly predicted using affective quality ratings, core affect scores are significantly lower in arousal, less extreme in valence, more variable between individuals, and less reproducible between studies. Nonetheless, stimuli rated with opposite valence between conditions range from 11% (study 1) to 17% (study 2). Lastly, we demonstrate that ambiguity in valence (i.e. high between-participants variability) explains violations of the V-shape and relates to higher arousal. (shrink)

This overview presents the most authoritative publications, theories and reflections of contemporary philosophers, culturologists and sociologists working on the study of cultural exclusion zones. There is a short introduction module, in which we have endeavoured to collate and highlight on the principal themes, terms, concepts and technical vocabulary developed to describe the specific phenomena of cultural exclusion zones. It is not intended as an exhaustive review of all aspects of the large agglomeration of themes related to Cultural Exclusion studies, but (...) focuses in particular on materials from the international “Mechanisms of Formation Zones of Cultural Exclusion and Frontier Areas” conferences (St. Petersburg, 2014, 2015, 2016 and 2017), some of which have also been selected for this edition of Rivista di Estetica. In this introduction we will present a selection of trends and individuals relating to the Russian and international interdisciplinary research project directed by the Centre for Cultural Exclusion and Frontier Zones of the Russian Academy of Sciences and the St. Petersburg State University as institutions, and by Sergey Troitskiy as theorist and visionary.In the following review we put forth the reflections of contemporary scientists on the phenomena of exclusion and re-actualization in conjunction with historical processes, along with an analysis of the origins and current state of the problem, and suggest ways to overcome cultural exclusion between various socio-demographic, national and socio-professional groups, as well as the social experience of separation from existing cultural values and norms through the development of a community’s cultural identity. The ideas reviewed propose various approaches to analysing the functional mechanisms of cultural exclusion, such as ontological, sociological, and humanitarian. (shrink)

We examine whether a taxpayer’s decision to choose a taxpayer-favorable characterization of income is associated with contextual and individual dimensions of that decision. Using a 2 × 2 factorial experimental design, we manipulate the prevailing social norm on whether there is a general belief that a specific form of income should be characterized as a capital gain or as ordinary income, and the group affiliation on whether the individual is making a tax characterization decision as a sole proprietor or as (...) a member of a group practice. Moreover, we measure participants’ fairness perception of characterizing the income as capital gains versus ordinary. We study the decisions of 180 graduate business and accounting students from two US business schools to explore these dimensions using a tax-ambiguous income situation. Results indicate that both contextual and individual dimensions impact taxpayer decisions. Specifically, the social norm and fairness perception of characterizing income as capital gains affects the likelihood of choosing such a characterization. Being a sole proprietor or a member of a group practice does not have any significant main effect. However, relative to all other conditions, taxpayers are most likely to characterize income as capital gains when both the social norms are for capital gains characterization and when the taxpayer is a member of a group practice. Results remain largely robust to a variety of alternative explanations. We conclude the paper with a discussion of our findings and their implications for tax policy, enforcement, and research.

A substantial body of experimental evidence has demonstrated that labels have an impact on infant categorization processes. Yet little is known regarding the nature of the mechanisms by which this effect is achieved. We distinguish between two competing accounts: supervised name‐based categorization and unsupervised feature‐based categorization. We describe a neurocomputational model of infant visual categorization, based on self‐organizing maps, that implements the unsupervised feature‐based approach. The model successfully reproduces experiments demonstrating the impact of labeling on infant visual categorization reported in (...) Plunkett, Hu, and Cohen (2008). It mimics infant behavior in both the familiarization and testing phases of the procedure, using a training regime that involves only single presentations of each stimulus and using just 24 participant networks per experiment. The model predicts that the observed behavior in infants is due to a transient form of learning that might lead to the emergence of hierarchically organized categorical structure and that the impact of labels on categorization is influenced by the perceived similarity and the sequence in which the objects are presented. The results suggest that early in development, say before 12 months old, labels need not act as invitations to form categories nor highlight the commonalities between objects, but they may play a more mundane but nevertheless powerful role as additional features that are processed in the same fashion as other features that characterize objects and object categories.

This is a comprehensive analysis of the idea of libertas and its conflicting uses in the political struggles of the late Roman Republic. By reconstructing Roman political thinking about liberty against the background of Classical and Hellenistic thought, it excavates two distinct intellectual traditions on the means allowing for the preservation and the loss of libertas. Considering the interplay of these traditions in the political debates of the first century BC, Dr Arena offers a significant reinterpretation of the political struggles (...) of the time as well as a radical reappraisal of the role played by the idea of liberty in the practice of politics. She argues that, as a result of its uses in rhetorical debates, libertas underwent a form of conceptual change at the end of the Republic and came to legitimise a new course of politics, which led progressively to the transformation of the whole political system.

Regulatory schema has shifted from government to governance-based systems. One particular form that has emerged at the international level is the multi-stakeholder voluntary code of conduct (MSVC). We argue that such codes are not only simply mechanisms by which various stakeholders attempt to govern the action of the corporation but also systems by which each stakeholder attempts to gain or retain some legitimacy goal. Each stakeholder is motivated by strategic legitimacy goal to join the code, and once a member, is (...) also required to assist in maintaining the institutional legitimacy of the code, resulting in “networked legitimacy.” We begin our analysis of these systems by first exploring the growth and structure of such MSVCs, and then building an analytical framework using strategic and institutional legitimacy as they apply to such MSVCs. We contribute to the codes of conduct literature by developing the construct of networked legitimacy from strategic and institutional legitimacy. We then apply our framework to the United Nations Global Compact, one of the predominant MSVCs today. In doing so, we: (1) demonstrate how different stakeholders are pursuing different types of legitimacy through their participation in the code, (2) examine the specific opportunities and risks in terms of what we have called “networked legitimacy” posed by the institutional design of actual MSVCs, and (3) create an argument for three pillars supporting the legitimacy of MSVCs.

We investigate conditions on and R which are sufficient and necessary for to (...) contain every Turing degree.

The outbreak of SARS-CoV-2 has exposed a shared condition of vulnerability on a global scale. How can we use vulnerability as an effective paradigm in order to foster collective political initiatives? This essay claims that the idea of care is key to understand the vulnerability framework as being both an epistemic and a political resource to address ethical issues. The first half of the essay recollects several arguments in Adriana Cavarero’s and Judith Butler’s most recent works, insofar as both theorists (...) have insisted on the notion of vulnerability in order to interpret contemporary political mobilizations. The second part of the essay retraces a constellation of practices of care in the works of several Black and decolonial feminist thinkers situated in different socio-political contexts. Whereas for Christina Sharpe and Saidiya Hartman the focus is on the matter of Blackness and Black lives in their constitutive vulnerability, both Cristina Rivera Garza’s and Sayak Valencia’s works remarkably insist on the specific socio-political context of today’s Mexico. These authors urge the readers to adopt a critical posture when encountering official narratives, also because in their texts they exhibit their own vulnerability. For them, writing, their writing is an ethical demand to imagine alternatives and to foster new entanglements between bodies persisting on the margins, at the limits of the norms that regulate legibility.

In this paper we (Laura Giordano, Nicola Olivetti and myself) propose a conditional logic to represent iterated belief revision systems. We propose a set of postulates for belief revision which are a small variant of Darwiche and Pearl's ones.The resulting conditional logic has a standard semantics in terms of selection function models, and provides a natural representation of epistemic states. A Representation Theorem establishes a correspondence between iterated belief revision systems and conditional models. Our Representation Theorem does not entail Gärdenfors' (...) Triviality Result.

Spectroscopy is a scientific topic at the interface between Chemistry and Physics, which is taught at high school level in relation with its fundamental applications in Analytical Chemistry. In the first part of the paper, the topic of spectroscopy is analyzed having in mind the well-known Johnstone’s triangle of chemistry education, putting in evidence the way spectroscopy is usually taught at the three levels of chemical knowledge: macroscopic/phenomenological, sub-microscopic/molecular and symbolic ones. Among these three levels, following Johnstone’s recommendations the macroscopic (...) one is the most useful for high school students who learn spectroscopy for the first time. Starting from these premises, in the second part of the paper, we propose a didactic sequence which is inspired by the historical evolution of spectroscopic instruments from the first spectroscopes invented by Gustav Kirchhoff and Robert Bunsen in 1860 to the UV–vis spectrophotometers which became common since the 1960s. The idea behind our research is to analyze the conceptual advancements through the history of spectroscopy and to identify the key episodes/experiments and spectroscopic instruments. For each of them, a didactic activity, typically an experiment, is then proposed underlining the relevant aspects from the chemistry education point of view. The present paper is the occasion to reflect on the potentialities of an historical approach combined with a laboratorial one, and to discuss the role of historical instruments and related technological improvements to teach spectroscopy.

The symbolic world of Corpus Areopagiticum is considered here from the prospect of the dichotomy in similar and dissimilar similarity (the images). The dissimilar images are divided into decent, average andthe distant ones. The similarand dissimilar images of Areopagite describe the world system by cataphatic and apophatic approach. The apophatic one seems to be noticeably more important for the author, as in denial (what God is not) or as in applying of unworthy predicates concerning him, his fundamental transcendence and unknowability (...) become more expressive. Similarand dissimilar images are both the divine names from the NewTestament and the Old Testament respectively. They allow the agent of cognition get closer to the understanding of the universe structure. The divine names correspond to the so-called universal concepts which are considered in the works of contemporary linguistic conceptualistics. Anthropomorphic and zoomorphic characters of the Scripture belong to the dissimilar images, such as parts of the human body, wild animals etc. The most distant dissimilar images should be analyzed as the manifestations of the human passions applied to the naming or description of God. This is the most controversial aspect of the dissimilar similarities because of their provocative character for a profane reader. Thomas Aquinas, one of the ardent admirers of the Corpus, has denied it while considering the theory of images ("The Mystical Theology"). The works of Areopagite have become an example of combining the Eastern and Western traditions ofargumentation which still remains within the framework of the Christian experience. (shrink)

Some philosophers claim that perception immediately and prima facie justifies belief in virtue of its phenomenal character (Huemer, Skepticism and the veil of perception. Rowman & Littlefield, Lanham, 2001; Pryor, There is immediate justification. In: Steup M, Sosa E (eds) Contemporary debates in epistemology. Blackwell, London (2014), pp. 181–202, 2005). To explain this special justificatory power, some appeal to perception’s presentational character: the idea that perceptual experience presents its objects as existing here-and-now (Chudnoff, Intuition. Oxford University Press, Oxford, 2013; Berghofer, (...) Husserl Stud 34(2):145–170, 2018). As some philosophers have noted, if perception justifies in virtue of its presentational character alone, the kind of content perception has should not matter for perceptual justification; more precisely, it should not matter whether perceptual content is propositional or not (e.g., Smithies, The epistemic role of consciousness. Oxford University Press, Oxford, 2019; Kriegel, Australas J Philos, 2021). However, most philosophers tend to resist this conclusion, holding that perception must be propositional in order to justify, on the ground that all our model of justification are propositional (e.g., Gauker, Philos Perspect 26(1):19–50, 2012). This paper challenges this claim. The paper consists of a negative and a positive part. In the negative part, I discuss and reject the master argument for the propositionality of perception; the conclusion is that propositional content is neither sufficient nor necessary to explain perception’s justificatory power. In the positive part, I take this conclusion seriously and outline an objectual model of perceptual justification. I define objectual attitudes as mental states whose content is not a full proposition, but a sub-propositional representational item, such as the representation of objects, properties, and kinds (Grzankowski and Montague, Non-propositional intentionality. Oxford University Press, Oxford, 2018), and show that it is plausible that some perceptions and some beliefs are attitudes of this kind. I then argue that objectual perceptual experiences have the right kind of phenomenal character and the right kind of structure to serve for immediate prima facie justification. I conclude by defending my objectual model from three objections. (shrink)
