We extend some of the classical connections between automata and logic due to Büchi [5] and McNaughton and Papert [12] to languages of finitely varying functions or “signals”. In particular, we introduce a natural class of automata for generating finitely varying functions called ’s, and show that it coincides in terms of language definability with a natural monadic second-order logic interpreted over finitely varying functions Rabinovich [15]. We also identify a “counter-free” subclass of ’s which characterise the first-order definable languages (...) of finitely varying functions. Our proofs mainly factor through the classical results for word languages. These results have applications in automata characterisations for continuously interpreted real-time logics like Metric Temporal Logic Chevalier et al. [6] and [7]. (shrink)

Proximity and interpersonal contact are prominent components of social connection. Giving affective touch to others is fundamental for human bonding. This brief report presents preliminary results from a pilot study. It explores if exposure to bonding scenes impacts the activity of specific muscles related to physical interaction. Fingers flexion is a very important component when performing most actions of affectionate contact. We explored the visuo-motor affective interplay by priming participants with bonding scenes and assessing the electromyographic activity of the fingers (...) flexor muscle, in the absence of any overt movements. Photographs of dyads in social interaction and of the same dyads not interacting were employed. We examined the effects upon the electromyographical activity: during the passive exposure to pictures, and during picture offset and when expecting the signal to perform a fingers flexion task. Interacting dyads compared to matched non-interacting dyads increased electromyographic activity of the fingers flexor muscle in both contexts. Specific capture of visual bonding cues at the level of visual cortex had been described in the literature. Here we showed that the neural processing of visual bonding cues reaches the fingers flexor muscle. Besides, previous visualization of bonding cues enhanced background electromyographic activity during motor preparation to perform the fingers flexion task, which might reflect a sustained leakage of central motor activity downstream leading to increase in firing of the respective motor neurons. These data suggest, at the effector level, an implicit visuo-motor connection in which social interaction cues evoke intrinsic dispositions toward affectionate social behavior. (shrink)

BackgroundPreprint usage is growing rapidly in the life sciences; however, questions remain on the relative quality of preprints when compared to published articles. An objective dimension of quality that is readily measurable is completeness of reporting, as transparency can improve the reader’s ability to independently interpret data and reproduce findings.MethodsIn this observational study, we initially compared independent samples of articles published in bioRxiv and in PubMed-indexed journals in 2016 using a quality of reporting questionnaire. After that, we performed paired comparisons (...) between preprints from bioRxiv to their own peer-reviewed versions in journals.ResultsPeer-reviewed articles had, on average, higher quality of reporting than preprints, although the difference was small, with absolute differences of 5.0% [95% CI 1.4, 8.6] and 4.7% [95% CI 2.4, 7.0] of reported items in the independent samples and paired sample comparison, respectively. There were larger differences favoring peer-reviewed articles in subjective ratings of how clearly titles and abstracts presented the main findings and how easy it was to locate relevant reporting information. Changes in reporting from preprints to peer-reviewed versions did not correlate with the impact factor of the publication venue or with the time lag from bioRxiv to journal publication.ConclusionsOur results suggest that, on average, publication in a peer-reviewed journal is associated with improvement in quality of reporting. They also show that quality of reporting in preprints in the life sciences is within a similar range as that of peer-reviewed articles, albeit slightly lower on average, supporting the idea that preprints should be considered valid scientific contributions.

BackgroundIn the Canadian Alliance for Healthy Hearts and Minds (CAHHM) cohort, participants underwent magnetic resonance imaging (MRI) of the brain, heart, and abdomen, that generated incidental findings (IFs). The approach to managing these unexpected results remain a complex issue. Our objectives were to describe the CAHHM policy for the management of IFs, to understand the impact of disclosing IFs to healthy research participants, and to reflect on the ethical obligations of researchers in future MRI studies.MethodsBetween 2013 and 2019, 8252 participants (...) (mean age 58 ± 9 years, 54% women) were recruited with a follow-up questionnaire administered to 909 participants (40% response rate) at 1-year. The CAHHM policy followed a restricted approach, whereby routine feedback on IFs was not provided. Only IFs of severe structural abnormalities were reported.ResultsSevere structural abnormalities occurred in 8.3% (95% confidence interval 7.7–8.9%) of participants, with the highest proportions found in the brain (4.2%) and abdomen (3.1%). The majority of participants (97%) informed of an IF reported no change in quality of life, with 3% of participants reporting that the knowledge of an IF negatively impacted their quality of life. Furthermore, 50% reported increased stress in learning about an IF, and in 95%, the discovery of an IF did not adversely impact his/her life insurance policy. Most participants (90%) would enrol in the study again and perceived the MRI scan to be beneficial, regardless of whether they were informed of IFs. While the implications of a restricted approach to IF management was perceived to be mostly positive, a degree of diagnostic misconception was present amongst participants, indicating the importance of a more thorough consent process to support participant autonomy.ConclusionThe management of IFs from research MRI scans remain a challenging issue, as participants may experience stress and a reduced quality of life when IFs are disclosed. The restricted approach to IF management in CAHHM demonstrated a fair fulfillment of the overarching ethical principles of respect for autonomy, concern for wellbeing, and justice. The approach outlined in the CAHHM policy may serve as a framework for future research studies.Clinical trial registrationhttps://clinicaltrials.gov/ct2/show/nct02220582. (shrink)

This study analyzes the morphophonemic variations among Kinamayo dialects. Purposeful sampling, in-depth interviews, sorting and classifying of words according to phonological and morphological structures in data analysis were used. Results revealed that the phonemic inventory of the Kinamayo dialects consisted of twenty segmental phonemes, fifteen consonants: /n/, /g/, /d/, /s/, /l/, /w/, /r/, /p/, /m/, /k/, /t/, /y/, /h/, /b/, /ŋ/; five basic vowels: /a/,/,/i/, /ɪ/, /u, /ʊ/; vowel lengthening: /a:/, /u:/ and three diphthongs: /aʊ/, /aɪ/, /ᴐɪ/. Consonant clusters are (...) mostly borrowed words and occur in the onset of the syllables. The analysis of Kinamayo phonology and morphology will serve as the basis for designing a functional orthography and lexicon of the language. Classification based on morphological structure revealed that the morphological processes common to Kinamayo are affixation, reduplication, deletion and derivation of one-word class from another. Affixation is the most productive morphological process in Kinamayo. Variation among the dialects was observed to involve phonological and morphological processes, voicing or phonation, and in terms of prefix for the markers in the past tense. Peculiarities in the phonological and morphological processes of dialects, as well as their areas of differences were observed to be associated primarily on geographical distribution.

The integration of artificial intelligence into bioethics education represents a new pedagogical approach that addresses complex moral issues in healthcare. The use of AI-driven platforms like ChatGPT in bioethics education can enhance critical thinking and decision-making skills among students by providing a diverse range of perspectives and solutions. To assess the ability of ChatGPT-4 to understand and resolve ethical dilemmas using validated clinical case vignettes, thereby determining its suitability as a teaching aid in bioethics. Ten clinical scenarios, each with inherent (...) ethical issues, were presented to ChatGPT-4. These scenarios were expert-validated to ensure relevance and complexity. ChatGPT's responses were evaluated by two blinded external raters to eliminate bias. The assessment criteria included identification of bioethical principles, recognition of stakeholders and their outcomes, and comprehension of ethical and legal frameworks. Additionally, the quality of responses was scored on a scale of 1–10. ChatGPT showed proficiency in identifying the pertinent bioethical principles and stakeholders involved in the ethical dilemmas presented. It achieved an overall score of 84.5%, with high marks for its analytical capabilities in complex scenarios. However, the study identified areas for improvement, particularly in proposing comprehensive solutions and alternative actions. ChatGPT demonstrates potential as an effective tool for bioethics education, capable of guiding learners through the resolution of ethical issues in clinical practice. However, to fully integrate ChatGPT into bioethics education, it requires enhancements in delivering detailed, actionable guidance in ethical decision-making. Future development should focus on refining ChatGPT’s ability to offer nuanced solutions aligned with patient values and clinician needs. (shrink)

Today’s pluralist and multicultural society raises questions about how to teach religiously and ethnically diverse students in Catholic schools. A Catholic Philosophy of Education addresses these challenges by examining the documents from the Roman Congregation for Catholic Education alongside the writings of Jacques Maritain and Bernard Lonergan. Mario D’Souza proposes a contemporary formulation for a Catholic philosophy of education in which the ideals of Catholicism form the basis for the mission of the Catholic school. Drawing on the Church’s educational documents, (...) and informed by Maritain and Lonergan, D’Souza explains how the unifying anthropology of Catholic education enables Catholic schools to serve amidst diversity by avoiding the extremes of religious exclusivism and fundamentalism, on the one hand, and relativism and individualism, on the other. He explores the aims of Catholic schools in relation to students, teachers, and society, and the relationship between goodness, discipline, and knowledge. He argues that students must be educated for personal and communal freedom and authenticity, and to strive for the common good, suggesting how a Catholic philosophy of education can provide the framework for such personal and communal transformation. Essential reading for new and experienced Catholic educators, A Catholic Philosophy of Education demonstrates that Maritain and Lonergan have much to offer in service of an education that is liberating, instructive, illuminating, and integrative.

The work of the lay Catholic philosopher Jacques Maritain continues to provoke and inspire readers to engage in a Thomistic approach to many of the questions facing the world today. Maritain’s wide-ranging thought touched on many fields, including aesthetics, anthropology, educational theory, moral philosophy, and ethics, as well as Thomism and its relationship to other philosophical stances._ In _Being in the World: A Quotable Maritain Reader_, Mario O. D’Souza, C.S.B., has selected seven hundred and fifty of the most salient quotations (...) found in the English translations of fifty-four works by Jacques Maritain. Organized into forty thematic chapters, ordered alphabetically, the book serves as an overview of the areas that Maritain's writings addressed. By referring to entries in _Being in the World_, readers can quickly locate key passages in Maritain’s writing on a given topic and then turn elsewhere to the full texts for more in-depth study. Complete with a detailed index of key terms, the _Reader _will be an essential reference tool for the study of Maritain in English. "Fr. Mario O. D'Souza's careful selection from the works of Jacques Maritain provides the reader with an invaluable sampling of Maritain's extensive philosophical work. In it, we find examples of Maritain's almost lyrical gift of expression as well as of his trenchant wit. More than a scholarly contribution, the volume also ably serves as an introduction and entrance into Maritain's corpus." — William Sweet, St. Francis Xavier University, Canada_. (shrink)

Die indische Philosophin und Aktivistin Radha d’Souza begegnet dem Begriff Weltzivilgesellschaft mit größter Vorsicht und Skepsis. Selbst jahrelang in existenzielle Auseinandersetzungen um Grundrechte auf natürliche Ressourcen wie Wasser und Ackerland und höchstgerichtliche Entscheidungen verwickelt, sieht d’Souza im Begriff der Weltzivilgesellschaft in der Hauptsache den Versuch, einer neuerlichen Bemäntelung imperialistischer, westlicher Interessen, die sich nun nicht nur durch Entscheidungen von Regierungen legitimieren, sondern gar durch den Willen ihrer zivilen Bevölkerung.

When Anquetil-Duperron landed at Pondicherry in 1755, in search of the sacred books of the “Indous et des Parses” (“Hindus and Parsees”), he surely had no idea that he was inaugurating a new discipline, Indianism. He returned to France in 1761, laden with a whole library of Indian texts which he was to spend the rest of his life deciphering. That year was a turning point in Indian history: the Marathes, on the verge of becoming the dominant power of the (...) entire Indian continent, were crushed in Panipat, north of Delhi, by the armies of an Afhgan invasion, and this catastrophe halted their advance for a while. During the same year, in the south of India, Lally-Tollendal was beaten and taken prisoner by the English, thereby destroying the French dream, shared by Dupleix and Bussy, of creating an Indian empire for themselves.

In Prior’s [4], Appendix A §4 and §5, and Chapter IV, and more explicitly in Bull’s [2], we find sequences of tense-logical systems which place increasingly more restrictive conditions on the temporal relation “… is before …”. We give here a simple, diagrammatic account of the way in which the successive postulates for temporal order place these conditions on the temporal relation: we do not provide any essentially new semantics for these systems, nor do we prove any rigorous metatheorems. We (...) do, however, quite often assume the completeness results of Lemmon, Bull and others without explicit mention. (shrink)
