According to the ancient commentaries, Iliad 21.195 was omitted by some sources, thereby making Acheloios, instead of Ocean, the origin of all waters, including the sea: the reasons for and the date of such a version of the text have been debated. In this paper 1 argue that the version without line 195 actually represents the earlier textual stage. This role of Acheloios is paralleled in the poem interpreted in the Derveni papyrus, and some features of Acheloios' cosmological function, as (...) well as his iconography, find interesting parallels in the Near East. As a 'cosmic' figure, Acheloios was in competition with Ocean, and is only rarely so represented in later preserved texts. His function as the origin of all fresh water and the source of all springs was more persistent, probably due also to his cultic role in Dodona: this, too, is probably reflected in another ancient variant for the text of Il. 16.234.

Dealing with fragmentary texts is an unavoidable task for anyone working on the Greco-Roman world with the awareness that only a tiny portion of the texts produced in antiquity has survived the perilous process of transmission. Since the Renaissance, generations of scholars have painstakingly collected and sifted quotations, paraphrases and allusions in later authors and grammatical sources, laying the foundation for our knowledge of large parts of that lost world. More recently a spectacular increase was made possible by the papyrological (...) discoveries. Even so, after centuries of explorations in this field, the evidence provided by the indirect sources and, in particular, by the still partly unpublished troves of medieval lexicographical excerpts and compilations is far from having been exhaustively exploited.

Existe uma tensão entre Teoria e História: “[...] a poesia é mais filosófica e de caráter mais elevado que a história, porque a poesia permanece no universal e a história estuda apenas o particular” (Aristóteles, 2007, 43). Esta afirmação de Aristóteles talvez tenha sido a primeira indicação da referida tensão entre as duas formas de conhecimento: a histórica e a teórica. Na citação acima, a filosofia é a referência de um pensamento hierarquicamente superior, sendo que sua legitimação enquanto tal passa (...) pela universalidade de suas verdades. É importante salientar que a poesia nesta reflexão aristotélica é uma forma de conhecimento, embora difira da história no que concerne à matéria do conhecido: na primeira, o fato poderia ter acontecido; na segunda, aconteceu. Porque aconteceu, o fato é singular, e que poderia ter acontecido cai no âmbito do universal. Neste sentido, a chave para a compreensão da tensão entre história e teoria é a universalidade ou singularidade do conhecimento adquirido: “[...] é evidente que não compete ao poeta narrar exatamente o que aconteceu; mas sim o que poderia ter acontecido, o possível, segundo a verossimilhança ou a necessidade. O historiador e o poeta não se distinguem um do outro, pelo fato de o primeiro escrever em prosa e o segundo em verso [...]. Diferem entre si porque um escreveu o que aconteceu e o outro o que poderia ter acontecido” (Aristóteles, 2007, 43). Ao situar a história em nível menos elevado que a poesia, Aristóteles parece ter suscitado em pensadores contemporâneos a ideia da distinção entre conhecimento histórico e conhecimento teórico. O presente estudo versa sobre a natureza do conhecimento histórico e seus impasses metodológicos no uso dos referenciais teóricos necessários às suas indagações fundamentais. (shrink)

O objetivo deste trabalho é estudar a relação que se estabelece entre as características da fenomenologia filosófica, a natureza do conhecimento que dela deriva e o modo como interfere sobre a produção do conhecimento em comunicação. Em primeiro lugar, observa-se a concepção de comunicação como processo transmissivo desenvolvida pelos clássicos estudos de mídia ou pelos processos de comunicação de massa. Em seguida, aproximam-se comunicação e semiótica como campos epistemológicos que, embora desenvolvam mútuas influências científicas, são, não raro, considerados áreas científicas (...) distintas atualmente, observa-se a emergência de outras bases de reflexão que podem aproximar a comunicação e a semiótica, enquanto áreas científicas.

Some studies highlighted that patients with narcolepsy type-1 experience high lucid dream frequency, and this phenomenon has been associated with a creative personality. Starting from the well-known “pandemic effect” on sleep and dreaming, we presented a picture of dream activity in pharmacologically treated NT1 patients during the Italian lockdown. Forty-three NT1 patients completed a web-survey during Spring 2021 and were compared with 86 matched-controls. Statistical comparisons revealed that: NT1 patients showed greater sleepiness than controls; controls showed higher sleep disturbances than (...) NT1 patients, and this result disappeared when the medication effect in NT1 was controlled; NT1 patients reported higher lucid dream frequency than controls. Focusing on dreaming in NT1 patients, we found that nightmare frequency was correlated with female gender, longer sleep duration, higher intrasleep wakefulness; dream recall, nightmare and lucid dream frequency were positively correlated with sleepiness. Comparisons between low and high NT1 lucid dreamers showed that patients more frequently experiencing lucid dreams reported a greater influence of dreaming during wakefulness, especially concerning problem-solving and creativity. Overall, our results are consistent with previous studies on pandemic dreaming carried out on healthy subjects. Moreover, we confirmed a link between lucidity and creativity in NT1 patients. Considering the small sample size and the cross-sectional design, our findings cannot provide a causal relationship between lucid dreams and the COVID-19 lockdown. Nevertheless, they represent a first contribution to address future studies on this issue, suggesting that some stable characteristics could interact with changes provoked by the pandemic. (shrink)

In recent literature there is unanimous agreement about children's pragmatic competence in drawing scalar implicatures about some , if the task is made easy enough. However, children accept infelicitous some sentences more often than adults do. In general their acceptance is assumed to be synonymous with a logical interpretation of some as a quantifier. But in our view an overlap with some as a determiner in under-informative sentences cannot be ruled out, given the ambiguity of the experimental instructions and the (...) attitude of trust by children in adults. Our study investigated this hypothesis with different experimental manipulations. We found that when the experimenter's intentions are clear (Experiment 1, all / some order effect; Experiments 2 and 4, conditions 2 and 3), under-informative sentences are usually rejected; otherwise (Experiment 1, some / all order effect; Experiments 3 and 4, control condition) they are accepted. However, analysis of verbal protocols indicated that pragmatically infelicitous sentences are accepted, with some interpreted mostly as a determiner, irrespective of the function of some as a quantifier. Acceptance is not in itself synonymous with a logical interpretation of some as a quantifier. (shrink)

We establish that the isomorphism problem for the classes of computable nilpotent rings, distributive lattices, nilpotent groups, and nilpotent semigroups is \-complete, which is as complicated as possible. The method we use is based on uniform effective interpretations of computable binary relations into computable structures from the corresponding algebraic classes.

Over the past decade, research has revealed biomolecular condensates' relevance in diverse cellular functions. Through a phase separation process, they concentrate macromolecules in subcompartments shaping the cellular organization and physiology. In the nucleus, biomolecular condensates assemble relevant biomolecules that orchestrate gene expression. We here hypothesize that chromatin condensates can also modulate the nongenetic functions of the genome, including the nuclear mechanical properties. The importance of chromatin condensates is supported by the genetic evidence indicating that mutations in their members are causative (...) of a group of rare Mendelian diseases named chromatinopathies (CPs). Despite a broad spectrum of clinical features and the perturbations of the epigenetic machinery characterizing the CPs, recent findings highlighted negligible changes in gene expression. These data argue in favor of possible noncanonical functions of chromatin condensates in regulating the genome's spatial organization and, consequently, the nuclear mechanics. In this review, we discuss how condensates may impact nuclear mechanical properties, thus affecting the cellular response to mechanical cues and, eventually, cell fate and identity.Chromatin condensates organize macromolecules in the nucleus orchestrating the transcription regulation and mutations in their members are responsible for rare diseases named chromatinopathies. We argue that chromatin condensates, in concert with the nuclear lamina, may also govern the nuclear mechanical properties affecting the cellular response to external cues. (shrink)

The objective of this article is to illustrate the issues and challenges which the higher education system in Bulgaria faces, with a particular accent on the phenomenon “education per kilogram”. The latter describes, in a popular language, the up-scaling of the university graduation, related to the mass proliferation of the higher education institutions, the facilitated access to enrolment through paid tuitions, etc. The big quantity of HEIs in the country is in a mismatch with the low percentage of GDP which (...) the government dedicates to education. The number of HEIs is also disproportionate against its population size - 54 HEIs in Bulgaria for population of 7.2 million. The research methodology includes a desktop study based on national statistical data and data from the governmentally-supported university rating system. An empirical survey, conducted among 250 tertiary education students enrolled in four Bulgarian universities, is a valuable contribution towards disclosing the pros and cons of the teaching practices in the tertiary education in the country. The first chapter describes at large the “education per kilogram” issue with regard to its possible origins, variations and consequences for the misbalance of labour market demand for certain qualifications and the universities supplies of qualified individuals. The second chapter reveals a comparative analysis by professional fields possible through the Ministry of Education and Science’s university rating system, i.e. students’ preferences for disciplines, universities and professions; the graduates’ professional fulfilment and how the income of the recent diploma-holders is a function of attending a particular HEI. The third chapter presents a sociological survey conducted among students in four Bulgarian universities which demonstrates learners’ attitudes towards various aspects of training, teaching methods and involvement in research assignments in the context of tertiary education. The main conclusion of the article is that the “universities per kilogram” trend brought about other corresponding characteristics, such as “students per kilogram”, “academic titles per kilogram”, etc. Hence, the large number of HEIs in Bulgaria has not led to improving the quality and efficiency of education, and yet does not respond adequately to the changing labour market demands for qualified professionals.

We construct a computable vector space with the trivial computable automorphism group, but with the dependence relations as complicated as possible, measured by their Turing degrees. As a corollary, we answer a question asked by A.S. Morozov in [Rigid constructive modules, Algebra and Logic, 28 570–583 ; 379–387 ].

Persae et Magi omnes qui Persicae regionis incolunt fines ignem praeferunt et omnibus elementis ignem putant debere praeponi. The Persians and all the Magi who dwell in the confines of the Persian land give their preference to fire and think it ought to be ranked above all the other elements.Iulius Firmicus Maternus was a Latin writer who lived in the fourth centurya.d. In the 340s, following his conversion to Christianity, he wrote theDe errore profanarum religionum, which has been preserved only (...) in the tenth-century manuscript Vaticanus Palatinus Latinus 165. In this work he argues against the pagan cults, calling for the emperors to suppress them. The first sections are dedicated to the pagan worship of the natural elements: objects of a cult are water among the Egyptians, earth among the Phrygians, air among the Assyrians. The chapter we are dealing with, the fifth, is dedicated to fire, a central element of the Zoroastrian religion. Greek and Roman writers, pagans and Christians alike, were aware of this, and references to some sort of fire-cult among Persians are numerous in literature and are found as early as Herodotus. Just like Firmicus Maternus, some authors also state that the Magi worship fire as a god or divine element and that they conduct fire-related rituals. In Greek and Latin authors there is a view that the Magi, these specialists of the rituals of the Persian religion, were originally a Median tribe. As shown by the passages of Ammianus and Basil, such knowledge was also available to Firmicus Maternus’ contemporaries, and there do not appear to be particular differences in the way in which Greek and Latin authors viewed the Magi in Achaemenid and Sassanid times. Regrettably, one cannot know for certain which of these sources Firmicus Maternus knew. (shrink)

Les débats sur la technique voient s'affronter souvent des positions tranchées entre technophiles et technophobes. On avancerait sans doute en déplaçant la question de la valeur et des dangers des artefacts techniques vers une réflexion philosophique plus profonde sur la technicisation de la vie et du monde, qui mérite généalogie et archéologie. Cet ouvrage, qui réunit plusieurs philosophes réputés de la question, veut à cet égard convoquer au débat les pensées de Martin Heidegger et de Michel Foucault qui ont permis (...) à travers leurs usages de la terminologie du Gestell et du dispositif de renouveler la question de la technique. Même si M. Foucault a été marqué par les analyses heideggériennes, il s'agit d'aller bien au-delà de la question des influences. Les langues d'appartenance de ces termes, leurs traductions deviennent aussi l'occasion d'explorer à nouveaux frais la complexité de la question. (shrink)

Quelle est la place du scepticisme dans l'œuvre d'un philosophe des Lumières comme Denis Diderot? Cet ouvrage vise à mettre en évidence les caractéristiques de la réception des instances sceptiques dans les œuvres de Diderot. L'analyse prend en considération l'ensemble du corpus diderotien, y compris sa contribution à l'Encyclopédie. L'objectif est aussi de montrer que la méthode sceptique de Diderot, qui consiste en l'usage de certaines argumentations, mais aussi en un ensemble de choix stylistiques, permet de mieux interpréter certaines spécificités (...) de sa pensée philosophique et de son matérialisme. Une meilleure compréhension du rôle du scepticisme dans la pensée de Diderot vise à apporter une contribution aux études sur ce qu'on définit comme le scepticisme des Lumières, en montrant qu'il serait plus exact de parler de scepticismes au pluriel, en raison des différences qui subsistent parmi les philosophes. Pour cette raison, ce livre propose des confrontations entre Diderot et ses sources sceptiques, mais aussi avec d'autres philosophes de son époque comme Montesquieu, Voltaire, D'Alembert et Hume"--Page 4 of cover.

R. Shore proved that every recursively enumerable set can be split into two nowhere simple sets. Splitting theorems play an important role in recursion theory since they provide information about the lattice ϵ of all r. e. sets. Nowhere simple sets were further studied by D. Miller and J. Remmel, and we generalize some of their results. We characterize r. e. sets which can be split into two effectively nowhere simple sets, and r. e. sets which can be split into (...) two r. e. non-nowhere simple sets. We show that every r. e. set is either the disjoint union of two effectively nowhere simple sets or two noneffectively nowhere simple sets. We characterize r. e. sets whose every nontrivial splitting is into nowhere simple sets, and r. e. sets whose every nontrivial splitting is into effectively nowhere simple sets. R. Shore proved that for every effectively nowhere simple set A, the lattice L* is effectively isomorphic to ϵ*, and that there is a nowhere simple set A such that L* is not effectively isomorphic to ϵ*. We prove that every nonzero r. e. Turing degree contains a noneffectively nowhere simple set A with the lattice L* effectively isomorphic to ϵ*. (shrink)

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)

BackgroundEvidence suggests that organizational models that provide care interventions including patient support programs may increase patient adherence to multiple sclerosis therapies by providing tailored symptom management, informational support, psychological and/or social support, lifestyle changes, emotional adjustment, health education, and tailored coaching, thus improving patients' overall quality of life across the disease course.ObjectiveThe main objective of this study was to describe MS patients' self-reported experience of a nurse-led, telephone-based PSP and to explore its potential role in improving disease and therapy management (...) skills.MethodsSurvey data were analyzed from a subset of patients relapsing–remitting MS using interferon beta-1a already registered in the adveva® PSP from three Italian multiple sclerosis centers with a consolidated experience in RRMS disease, treatment management, and PSP programs.ResultsIn total, 244 patient data at baseline were analyzed, of which 115 had a follow-up of at least 6 months. Results from this study provide an early view into the role of this PSP in improving the patients reported overall experience regarding disease management and injectable therapy, thus potentially ameliorating treatment adherence and decreasing health care cost. Moreover, study findings confirm the role of providing a patient-focused support by addressing non-medication-related topics in the PSP consultations. Indeed, patients involved in the adveva® PSP program reported a better psychological status in the follow up as demonstrated by an increased optimism regarding their future, tolerance of disease uncertainty, and their perceived ability to benefit from external help and social support.ConclusionsAs such, it is reasonable to conclude that the involvement in the adveva® PSP and the PSP's assistance in guiding patients on proper treatment self-management techniques is of great value to patients as it might contribute to improving engagement in their health care journey in terms of perceived self-care skills, emotional coping toward the future and the unpredictability of the disease course and their general attitudes toward the injection itself, involving pain tolerance.

Aujourd’hui, il n’est pas possible de vivre autrement que par conspiration. Mais, aujourd’hui, il n’est pas non plus possible de vivre par complot. Pour vivre maintenant, pour créer des modes de vie, des formes de vie, nous devons chercher une conspiration sans complot, une conspiration qui soit sa propre fin, une conspiration qui soit en vue d’elle-même.

Cet article questionne la situation de la littérature au temps de la mondialisation. Le désir du sinologue François Jullien de découvrir s’il y a encore la possibilité d’établir un dialogue entre les cultures — pas en termes d’identité, mais d’écart et de fécondité culturelle — a suscité ma curiosité. Comment la littérature et l’imaginaire des lecteurs sont-ils en train de se modifier? Notre terrain d’observation privilégié sera celui de ce que nous appellerons l’écriture migrante, lorsque les écrivains immigrés utilisent la (...) langue du pays d’accueil pour écrire leurs histoires. Ce sujet, à son tour, conduit aux questions du canon littéraire, de l’intertextualité et de l’interprétation comme base lexicale pour la réécriture d’un nouveau réseau de mots-clés de la littérature, à l’époque de la postmodernité. The main aspect of this article concerns the situation of literature in the time of globalization. We have organized this work on the base of François Jullien’s theory about the possibility to establish a cultural dialogue, not in terms of identity, but in terms of difference and cultural fecundity. How literature and the reader’s imaginary are changing? In order to extend this research we have also considered the problem of the migrant writing: a kind of writing realized by migrant writers, who use the language of the host country in their stories. An issue that puts in evidence other problems, such as the discussion about literary canon, the subjects of interpretation and intertextuality in terms of innovative keywords to reflect on the postmodern literature.

A Turing degree d is homogeneous bounding if every complete decidable (CD) theory has a d-decidable homogeneous model A, i.e., the elementary diagram De (A) has degree d. It follows from results of Macintyre and Marker that every PA degree (i.e., every degree of a complete extension of Peano Arithmetic) is homogeneous bounding. We prove that in fact a degree is homogeneous bounding if and only if it is a PA degree. We do this by showing that there is a (...) single CD theory T such that every homogeneous model of T has a PA degree. (shrink)

The aim of this cross-sectional study is to investigate the role of psychological inflexibility in the relationship between anxiety and depression and emotional eating in a sample of 123 inpatient Italian adult individuals with obesity. Participants completed the Anxiety and Depression subscales of the Psychological General Well-Being Inventory, the Acceptance and Action Questionnaire, and the Emotional Eating subscale of the Dutch Eating Behavior Questionnaire to assess anxiety and depression, psychological inflexibility, and emotional eating, respectively. Results showed that the indirect effect (...) of PGWBI-A on DEBQ-EE through AAQ-II was significant [b = −0.0155; SE = 0.076; 95% BC-CI ]. Similarly, the indirect effect of PGWBI-D on DEBQ-EE through AAQ-II was significant [b = −0.0383; SE = 0.0207; 95% BC-CI ]. These findings may help to plan and develop specific psychological interventions aimed at addressing emotional eating through targeting psychological inflexibility to be included in obesity treatment programs.

Au cours de la guerre froide, les organisations internationales, notamment celles du système de l’ONU, sont des tribunes instrumentalisées par les deux superpuissances pour se mettre en valeur. C’est le cas de l’UNESCO. Le discours de la cosmonaute soviétique Valentina Terechkova en 1966 est la première prise de parole d’une femme soviétique dans cette enceinte. Terechkova, qui a été la première femme au monde à effectuer, en 1963, un vol dans l’espace, utilise la tribune de l’UNESCO pour introduire des (...) enjeux de genre dans le cadre des relations internationales marquées par le contexte de guerre froide.
