La testimonianza per sentito dire, nonostante la sua evidente inadeguatezza a fornire conoscenze certe sui fatti avvenuti, viene utilizzata nei processi penali fin dall’Alto Medioevo. Il saggio ripercorre la riflessione della scienza giuridica medievale, in particolare di Bartolo da Sassoferrato, sulla formazione del convincimento del Giudice, per offrire un contributo alla comprensione dei motivi dell’utilizzo di questo anomalo strumento di prova anche nel processo penale contemporaneo. _Hearsay evidence, despite its evident inadequacy to provide certain knowledge about the events (...) that occurred, has been used in criminal trials since the Early Middle Ages. The essay traces the reflection of medieval legal science, in particular by Bartolo da Sassoferrato, on the formation of the Judge's conviction, to offer a contribution to understanding the reasons for the use of this anomalous evidence also in contemporary criminal trials_.

In this historical article, Newton da Costa discusses Francisco Miró Quesada’s philosophical ideas about logic. He discusses the topics of reason, logic, and action in Miró Quesada’s work, and in the final section he offers his critical view. In particular, he disagrees with Miró Quesada’s stance on the historicity of reason, for whom “reason is essentially absolute”, whereas for da Costa it “is being constructed in the course of history”. Da Costa concludes by emphasizing the importance of Miró Quesada’s theory (...) of logic and reason, despite it still being incomplete. -/- Historical article by Newton da Costa, annotated and translated by J.

Research has demonstrated that policing is a stressful occupation and has a negative impact on police officers’ mental and physical health, performance, and interactions with citizens. Mental health at the workplace has become a concern due to the costs of depression, anxiety, burnout, and even suicide, which is high among police officers.To ameliorate occupational health, it is crucial therefore to identify stress and burnout levels on a regular basis. However, the instruments frequently used to measure stress have not valorized the (...) specificity of policing tasks. This study aims: i) conducting a literature review, to identify questionnaires used to assess occupational stress and burnout among police officers; ii) to analyze the psychometric characteristics of a Portuguese version of Operational Police Stress Questionnaire (PSQ-Op); and, using the PSQ-op and other questionnaires, iii) to identify operational stress, burnout, and distress levels among Portuguese police officers. The literature review identified 108 studies, which use a multiplicity of questionnaires to measure burnout or occupational stress among police officers, but few studies use specific police stress questionnaires. Sample sizes were mostly below 500 participants and studies were mainly developed in the last decade in the USA and Brazil, but also in another 24 countries, showing the extent of the interest in this topic. This study applied to 2057 police officers from National Portuguese Police, a force policing urban centers, the PSQ-Op, as well the Spanish Burnout Inventory and the Kessler Psychological Distress Scale.The results show that the psychometric properties of the Portuguese version of PSQ-Op are adequate. Factorial analysis revealed two dimensions defined as social and work issues, which were associated with measures of distress and burnout.Fit indices suggested a second-order solution called operational police stress. Overall, and considering the scale range of each questionnaire, the results showed moderate values of operational stress, distress, and burnout. However, considering their cut-off points, 85% of the sample presented high operational stress levels, 11% critical values for burnout, and 28% high distress levels, with 55% of the sample at risk of psychological disorder. These results reinforce the need to prevent stress and to invest in police officers’ occupational health. (shrink)

This article contains an implicit comparison of the institutions and thought of the Italian city republics in the period from about 1150 to 1350 with medieval and early-modern monarchies and oligarchical republics, the latter being exemplified here by a passage from Bartolo of Sassoferrato. The grammarians, notaries, and jurists treated here are representative of the secular or lay professionalism that first emerged on a large scale in these republics. To these have been added occasional clerks who show the (...) influence of these legal and secular traditions, including Ptolemy of Lucca , whose On Princely Government continued a work by the far more famous Dominican Thomas Aquinas and hence enjoyed wide circulation and great influence. His work shows evidence of the influence of the translation of Aristotle's Politics done c. 1260; the only other author treated here who absorbed part of that tradition is the civilian jurist Bartolo of Sassoferrato. Most of the lawyers and other professionals derived their ideas from Roman law and, to a lesser extent, from Seneca and even Cicero. Readers may be surprised to observe that Marsiglio of Padua, surely Italy's premier political thinker, is not seen here at all or, rather, only once mentioned in passing. A reason for this is that he is much discussed in today's scholarly literature of political theory. A main intention of this author, however, has to do with him. It is to help explain the world he came from. If exaggerated, A. J. Carlyle's observation remains sound. Marsiglio, he said, “is not … setting out some new and revolutionary democratic doctrine, but is rather expressing, even if in rather drastic and unqualified terms, the normal judgement and practice of the [Italian] Middle Ages.

This book is concerned with the role of economic philosophy in the processes of belief-formation and social change. Its aim is to further our understanding of the behaviour of the individual economic agent by bringing to light and examining the function of non-rational dispositions and motivations in the determination of the agent's beliefs and goals. Drawing on the work of David Hume and Adam Smith the book spells out the particular ways in which the passions come to affect our ordinary (...) understanding and conduct in practical affairs and the intergenerational and interpersonal transmission of ideas through language. Concern with these problems, it is argued, lies at the heart of an important tradition in British moral philosophy. This emphasis on the non-rational nature of our belief-fixation mechanisms has important implications: it helps to clarify and qualify the misleading claims often made by utilitarian, Marxist, Keynesian and neo-liberal economic philosophers, all of whom stress the overriding power of ideas to shape conduct, policy and institutions.

I present here my criticism of Chateaubriand’s account of propositions as having an identifying character with respect to reality. I claim that propositions are better understood as pictures of possible states-of-affairs, and that this account is more natural considering the acts of judgment that are at the origin of propositions. I also present a possible way of understanding the notion of a possible state-of-affairs that takes care of the seemingly absurd case of necessarily false, but meaningful propositions.

O presente trabalho tem como objetivo central indicar alguns pontos de aproximação e distinção entre o sentido atribuído por Kierkegaard à angústia na obra O conceito de angústia, e o modo pelo qual Heidegger aborda tal conceito no âmbito da analítica existencial desenvolvida em Ser e tempo. Muito embora seja possível apontar inegáveis semelhanças no modo pelo qual os dois autores compreendem o fenômeno da angústia, algumas distinções podem ser feitas se analisados os contextos a partir dos quais os pensadores (...) se ocuparam do tema em questão. Enquanto que para Kierkegaard a angústia é vista em estrita relação com o pecado, a fé e a liberdade, Heidegger busca atribuir ao fenômeno do angustiar-se um sentido ontológico, inscrito no projeto da ontologia fundamental, a partir do qual torna-se possível ao Dasein ser livre para escolher a si mesmo, e assim assumir o modo próprio de ser.

In this paper I study the variants of the notion of completeness Husserl pre-sented in “Ideen I” and two lectures he gave in Göttingen in 1901. Introduced primarily in connection with the problem of imaginary numbers, this notion found eventually a place in the answer Husserl provided for the philosophically more im-portant problem of the logico-epistemological foundation of formal knowledge in sci-ence. I also try to explain why Husserl said that there was an evident correlation between his and Hilbert’s notion (...) of completeness introduced in connection with the axiomatisation of geometry and the theory of real numbers when, as many commen-tators have already observed, these two notions are independent. I show in this paper that if a system of axioms is complete in Husserl’s sense, then its formal domain, the manifold of formal objects it determines, does not admit any extension. This is precisely the idea behind Hilbert’s notion of completeness in question. Therefore, the correlation Husserl noted indeed exists. But, in order to see it, we must consider the formal domain determined by a formal theory, not its models. (shrink)

As part of a continuous process to explore the factors that might weaken or corrupt traditional peer review, in this paper, we query the ethics, fairness and validity of the request, by editors, of authors to suggest peer reviewers during the submission process. One of the reasons for the current crisis in science pertains to a loss in trust as a result of a flawed peer review which is by nature biased unless it is open peer review. As we indicate, (...) the fact that some editors and journals rely on authors’ suggestions in terms of who should peer review their paper already instills a potential way to abuse the trust of the submission and publishing system. An author-suggested peer reviewer choice might also tempt authors to seek reviewers who might be more receptive or sympathetic to the authors’ message or results, and thus favor the outcome of that paper. Authors should thus not be placed in such a potentially ethically compromising situation, especially as a mandatory condition for submission. However, the fact that they do not have an opt-out choice during the submission process—especially when using an online submission system that makes such a suggestion compulsory—may constitute a violation of authors’ rights.

O presente artigo busca analisar os processos, fluxos e refluxos, de desterritorialização e territorialização, no contexto da diáspora negra no Brasil. Através dos conceitos de quilombismo e comunidade, examinará as comunidades virtuais “Ponte para Pretx” e “Intelectuais Negras: escrita de si mesma” localizadas no Facebook, articulando ponderações e reflexões em torno dos processos de empoderamento negro, ativismo, solidariedade e resistência negra, nucleados na ideia de comunidade virtual. Desta maneira, através dos pressupostos da hermenêutica histórica, a pesquisa demonstrará de que maneira (...) as comunidades virtuais fortalecem a cultura negra, segundo a potência de construir territórios de sentido às populações negras brasileiras em torno de arranjos e organizações sociais e culturais.

Introdução: A pressão expiratória final positiva-pressão expiratória final zero (PEEP-ZEEP) é uma técnica fisioterapêutica para desobstrução brônquica. Objetivo: Avaliar os efeitos agudos da PEEP-ZEEP comparada à hiperinsuflação manual (HM) em pacientes críticos traqueostomizados em relação à segurança e eficiência para higiene brônquica. Métodos: Indivíduos submetidos à ventilação mecânica invasiva por cânula de traqueostomia foram aleatorizados em dois grupos, um que recebia a técnica PEEP-ZEEP primeiramente, e outro que recebia HM. A coleta das variáveis cardiorrespiratórias foi realizada antes, 1 minuto e (...) 30 minutos após cada técnica, bem como o peso da secreção pulmonar aspirada. Resultados: Para 18 pacientes com média de idade de 66,4 (17,3) anos, não foram encontradas diferenças entre grupos para nenhuma das variáveis hemodinâmicas e respiratórias. A quantidade de secreção pulmonar removida também foi semelhante entre as técnicas. Conclusão: PEEP-ZEEP e hiperinsuflação manual não diferem entre si em relação à depuração de secreções brônquicas e variáveis cardiorrespiratórias. (shrink)

Este artigo propõe uma reflexão crítica sobre a relação entre a noção de dever em Kant e a concepção de desejo na ética psicanalítica freudo-lacaniana. Kant fundamenta o dever moral na ideia de boa vontade, e na universalização da razão. Em contraste, na psicanálise freudolacaniana o senso de dever é moldado pela interação complexa entre desejos inconscientes, socialização e a busca pelo equilíbrio entre pulsões individuais e normas sociais. Concluímos que esta tensão intrínseca ao ser humano destaca a necessidade de (...) compreender a ética humana considerando não apenas a racionalidade, mas também a complexidade e a variedade dos desejos inconscientes.

Retractions of COVID-19 literature in both preprints and the peer-reviewed literature serve as a reminder that there are still challenging issues underlying the integrity of the biomedical literature. The risks to academia become larger when such retractions take place in high-ranking biomedical journals. In some cases, retractions result from unreliable or nonexistent data, an issue that could easily be avoided by having open data policies, but there have also been retractions due to oversight in peer review and editorial verification. As (...) COVID-19 continues to affect academics and societies around the world, failures in peer review might also constitute a public health risk. The effectiveness by which COVID-19 literature is corrected, including through retractions, depends on the stringency of measures in place to detect errors and to correct erroneous literature. It also relies on the stringent implementation of open data policies. (shrink)

The method of morphisms is a well-known application of Dialectica categories to set theory. In a previous work, Valeria de Paiva and the author have asked how much of the Axiom of Choice is needed in order to carry out the referred applications of such method. In this paper, we show that, when considered in their full generality, those applications of Dialectica categories give rise to equivalents of either the Axiom of Choice or Partition Principle —which is a consequence of (...) $\textbf{AC}$ whose precise status of its relationship with$\textbf{AC}$ itself is an open problem for more than a hundred years.

O presente trabalho apresenta os bastidores de uma pesquisa realizada sobre a Faculdade Católica de Filosofia de Rio Grande (1960- 1969), cuja criação marcou o início dos cursos superiores voltados à formação docente na cidade. Para destacar sua história, recorre-se a diferentes fontes, como documentos institucionais, jornais locais e relatos orais, cuja utilização será aqui abordada. Nesse sentido, tem-se como base os caminhos abertos pela História Cultural as quais vêm propiciando a ampliação de problemas, objetos e temas de pesquisa histórica. (...) Constata-se que a multiplicidade de histórias e memórias sobre essa instituição educacional só foram descortinadas devido à ampliação do olhar sobre as diferentes fontes de pesquisa. (shrink)

In [7] the authors of this paper argued in favor of the possibility to consider a Paraconsistent Approach to Quantum Superpositions. We claimed that, even though most interpretations of quantum mechanics attempt to escape contradictions, there are many hints -coming from present technical and experimental developments in QM- that indicate it could be worth while to engage in a research of this kind. Recently, Arenhart and Krause have raised several arguments against the PAQS [1, 2, 3]. In [11, 12] it (...) was argued that their reasoning presupposes a metaphysical stance according to which the physical representation of reality must be exclusively considered in terms of the equation: Actuality = Reality. However, from a different metaphysical standpoint their problems disappear. It was also argued that, if we accept the idea that quantum superpositions exist in a potential realm, it makes perfect sense to develop QM in terms of a paraconsistent approach and claim that quantum superpositions are contradictory, contextual existents. Following these ideas, and taking as a standpoint an interpretation in terms of the physical notions of power and potentia put forward in [10, 12, 15], we present a paraconsistent formalization of quantum superpositions that attempts to capture the main features of QM.

Charles Darwin's curiosity had a remarkable childlike enthusiasm driven by an almost compulsive appetite for a constant process of discovery, which he never satiated despite his many voyages. He would puzzle about the smallest things, from the wonders of barnacles to the different shapes, colours and textures of the beetles which he obsessively collected, from flowers and stems to birds, music and language, and would dedicate years to understanding the potential significance of everything he saw. Darwin's findings and theories relied (...) heavily on that same curiosity, on seeking and answering questions, however long these would take to clarify. His son Francis Darwin often recalls how "he would ask himself 'now what do you want to say' and his answer written down would often disentangle the confusion". In fact, "disentangling confusions" seems to have been the driving force behind Darwin's scientific pursuits, as he was struck with bewilderment when contemplating the luxuriousness of life. It was also the impetus for this book. The true implications of Darwin's legacy remain as controversial to the critics of our time as they were to his contemporaries. Darwin's impact within and beyond the biological sciences is both daunting and exhilarating, and attests to the need for an interdisciplinary approach by remaining a challenge to many scholars in the most diverse fields. The recent revival of his theories has opened a Pandora's box of different theoretical studies that are particularly receptive to exploring new and exciting angles of research. (shrink)

La retórica siempre ha mantenido estrechas relaciones con otros géneros literarios en la antigüedad. Con el teatro, en particular, sus relaciones inter y extratextuales son aún más evidentes. En este artículo, tenemos la intención de investigar este enfoque basado en tres personajes típicos de la nueva comedia romana: senex, adulescens y meretrix puestos en escena bajo las tramas de amor más irreverentes, responsables del entrelazamiento de estos personajes. Partimos de Excerptum 37 de Calpúrnio Flaco y Declamatio Minor 356 de Pseudo-Quintiliano, (...) señalando su correspondencia con la obra Mercator de Plauto, cuyo argumento es muy similar al de las declaraciones.
