Over recent years, the research community has been increasingly using preprint servers to share manuscripts that are not yet peer-reviewed. Even if it enables quick dissemination of research findings, this practice raises several challenges in publication ethics and integrity. In particular, preprints have become an important source of information for stakeholders interested in COVID19 research developments, including traditional media, social media, and policy makers. Despite caveats about their nature, many users can still confuse pre-prints with peer-reviewed manuscripts. If unconfirmed but (...) already widely shared first-draft results later prove wrong or misinterpreted, it can be very difficult to “unlearn” what we thought was true. Complexity further increases if unconfirmed findings have been used to inform guidelines. To help achieve a balance between early access to research findings and its negative consequences, we formulated five recommendations: (a) consensus should be sought on a term clearer than ‘pre-print’, such as ‘Unrefereed manuscript’, “Manuscript awaiting peer review” or ‘’Non-reviewed manuscript”; (b) Caveats about unrefereed manuscripts should be prominent on their first page, and each page should include a red watermark stating ‘Caution—Not Peer Reviewed’; (c) pre-print authors should certify that their manuscript will be submitted to a peer-review journal, and should regularly update the manuscript status; (d) high level consultations should be convened, to formulate clear principles and policies for the publication and dissemination of non-peer reviewed research results; (e) in the longer term, an international initiative to certify servers that comply with good practices could be envisaged.

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.

Situado no campo da discussão entre a filosofia da vida e a fenomenologia, ou mais especificamente entre a escola diltheiana e o círculo fenomenológico, o artigo investiga em que esfera Dilthey é, de fato, relativista, e, no caso afirmativo, até que ponto é possível extrair, de sua posição diante da história, consequências céticas.

O propósito sistemático-filosófico da crítica diltheiana da razão histórica traduz-se na busca de apoio do conhecimento objetivo para sua apreensão intuitiva da vida. O presente artigo busca mostrar não só aspectos da trajetória teórica do autor, mas também suas dificuldades e limites.

A presente tradução é do texto que John Burnet (1863-1928) leu para a Academia Britânica em 2 de julho de 1924. O texto foi publicado naquele mesmo ano nos Proceedings of the British Academy, e também integra a coletânea póstuma de escritos de Burnet, Essays and Addresses, publicada em 1929. O tema principal é acerca do estabelecimento de uma cronologia das obras de Aristóteles, cuja discussão é marcada pela, então, recente publicação de um livro de Werner Jaeger sobre Aristóteles.

Na obra Eichmann em Jerusalém – um relato sobre a banalidade do mal, Hannah Arendt descreve em determinada passagem que o réu Otto Adolf Eichmann invoca o imperativo categórico de Immanuel Kant, na busca de justificar sua conduta criminosa no massacre ocorrido na Alemanha nazista. Inertes numa sociedade desfigurada e que apresentava novas leis, tanto o réu quanto os demais criminosos viviam sob um véu de cegueira, que não poderia, porém, ser fundamento para a barbaridade cometida. Pretende-se com esse artigo (...) elucidar o imperativo categórico de Kant empregado na ótica das leis da razão e, analisar o mau uso da autoridade de Kant por Eichmann. (shrink)

Tradução inédita do texto Vauvenargues de Émile Bréhier (1876-1952). Este texto é o nono capítulo, do quarto livro da magistral Histoire de la philosophie de Bréhier, que vem recebendo diversas edições desde 1930.

O texto é uma resenha de uma obra do filósofo e psicólogo alemão Wilhelm Dilthey. A resenha aborda uma publicação para o português da obra Filosofia e educação na data em que se celebra o centenário de morte de Dilthey. A iniciativa dessa análise se justifica por ressaltar esta edição que: apresenta ao público brasileiro este autor relativamente pouco conhecido em nosso país; introduz os termos de sua filosofia. Dilthey é pensador crucial para o século XX por ter contestado a (...) influência que a doutrina positivista possuiria sobre as ciências humanas (especialmente as sociais, as históricas e as do psiquismo) com seu método hermenêutico. A influência deste pensador se fez sensivelmente presente na obra de autores como Weber, Simmel, Spengler, Ortega y Gasset, Heidegger e Gadamer. (shrink)

O terceiro volume da biografia política de Álvaro Cunhal por Pacheco Pereira («O pri­sioneiro») centra-se no período 1949-1960, o do encarceramento mais longo a que Cunhal es­teve sujeito e do qual só saiu numa das mais céleres fugas prisionais da nossa história, a de Pe­niche. Curiosamente, os elogios desmedidos de que foram objecto os dois volumes anteriores começam agora a justificar-se, apesar de a recepção a este volume ter sido bem mais discreta, ainda que como de costume unanimista (ne...

A obra Hacking e dispositivos tecnológicos nos faz compreender que um computador não é somente uma máquina que corresponde aos cliques do mouse, mas uma realidade técnica que permite estar em contato com o universo inteiro. Essa realidade tem na internet um instrumento poderoso dotado de algoritmos por meio dos quais é possível conduzir nossas condutas por um universo grandioso no qual aprendemos a participar de grupos, a sorrir, a odiar, a amar, a trabalhar, comer, acordar, dormir, entre outros. Contudo, (...) é importante nos precavermos contra a tecnofobia, ou sentir que a internet é uma encarnação do mal. Não é isso, a internet abre espaços para ter bons encontros, conhecer os mais variados objetos técnicos e construir uma aprendizagem por meio da experimentação. (shrink)

Investigates the resolution of contradictions and ambiguous derogations in a code, by means of the imposition of partial orderings.

A study in the logic of theory change, examining the properties of maxichoice contraction and revision operations.

This paper is concerned with formal aspects of the logic of theory change, and in particular with the process of shrinking or contracting a theory to eliminate a proposition. It continues work in the area by the authors and Peter Gärdenfors. The paper defines a notion of safe contraction of a set of propositions, shows that it satisfies the Gärdenfors postulates for contraction and thus can be represented as a partial meet contraction, and studies its properties both in general and (...) under various natural constraints.

In some recent papers, the authors and Peter Gärdenfors have defined and studied two different kinds of formal operation, conceived as possible representations of the intuitive process of contracting a theory to eliminate a proposition. These are partial meet contraction (including as limiting cases full meet contraction and maxichoice contraction) and safe contraction. It is known, via the representation theorem for the former, that every safe contraction operation over a theory is a partial meet contraction over that theory. The purpose (...) of the present paper is to study the relationship more finely, by seeking an explicit map between the component orderings involved in each of the two kinds of contraction. It is shown that at least in the finite case a suitable map exists, with the consequence that the relational, transitively relational, and antisymmetrically relational partial meet contraction functions form identifiable subclasses of the safe contraction functions, over any theory finite modulo logical equivalence. In the process of constructing the map, as the composition of four simple transformations, mediating notions of bottom and top contraction are introduced. The study of the infinite case remains open.

Davidson’s treatment of akrasia resorts to the introduction of a type of operator, the prima facie connector. This operator should yield conditional judgments in which the affirmation of the antecedent does not admit to obtain the consequent as a separate conclusion; and it must allow to separate ..

The purpose of the paper is to present a logical framework that allow to formalize a kind of prima facie duties, defeasible conditional duties, indefeasible conditional duties and actual (indefeasible) duties, as well as to show their logical interconnections.

Between the two horns of Jørgensen's dilemma, the authors opt for that according to which logic deals not only with truth and falsity but also with those concepts not possessing this semantic reference. Notwithstanding the “descriptive” prejudice, deontic logic has gained validity among modal logics. The technical foundation proposed consists in an abstract characterization of logical consequence. By identifying in the abstract notion of consequence the primitive from which to begin, it is possible to define the connectives - even those (...) of obligation - by means of the rules of introduction or elimination in a context of derivation.

Este artigo pretende expor a teoria cartesiana da criação encontrada nas Meditações, da qual decorre coerentemente a teoria da livre criação das verdades eternas desenvolvida por Descartes nas Cartas, entre os anos de 1630 e 1649. Fazendo isso, tenta-se refutar interpretações segundo as quais a teoria da livre criação seria marginal ou incompatível com o sistema cartesiano. Para tanto, apresentaremos a concepção tomasiana da criação e a gradativa refutação cartesiana da mesma, donde emerge uma moderna teoria da criação, fundamento sine (...) qua non da teoria da livre criação das verdades eternas.

Teniendo como punto de partida el importante intercambio crítico entre John Rawls y Jürgen Habermas desplegado en The Journal of Philosohy en marzo de 1995, el presente escrito tiene por objetivo explorar el lugar que ocupa el consenso en la fundamentación del pensamiento político de ambos autores. De modo tal que pueda ponerse en evidencia el carácter intersubjetivo que subyace tanto en los planteos de la teoría de la justicia de Rawls como en la ética del discurso habermasiana. Lo anterior, (...) en efecto, implica un ejercicio conceptual que decanta en el esclarecimiento de dos sendas argumentativas, ambas herederas de una interpretación de Kant, encauzadas a dar solución a la fundamentación de principios morales en las sociedades plurales contemporáneas.

The main purpose of this paper is to explore the role played by logic in the legal domain. In the traditional conception which underlies the movement of codification, judges are able to find in the legal system (the Master System) a unique answer for every legal problem. This entails its completeness, consistency and the possibility of deriving from it the contents of all judicial decisions. Although the ideal model of this conception is supported by important theoretical and political ideals, it (...) has significant shortcomings. The elements of normative systems (Master Systems) are “norms” and not mere “norm-formulations.” A “norm” is the meaning attributed to normative linguistic expressions. The set of all normative expressions, such as statutes, codes, etc. forms what is called the Master Book. One of the main problems for the ideal model is the identification of a normative system behind the Master Book. Interpretative arguments are the tools designed to solve these problems. Although the requirements of the model are not totally fulfilled in actual practice, it remains as an effective ideal rational goal behind legal activities linked to adjudication and most theoretical approaches to law.

Standardly, the usual approach to rationality is based on the notion of ‘being a reason for’. Honouring the traditional distinction between practical and theoretical philosophy, reasons are classified as justificative and explicative. In both cases, a reason-statement has the form ‘’. For reasons of type , ‘A’ is a factual statement and ‘B’ is a statement which describes an action of the agent. The reason-statement has a prescriptive sense because ‘A is a reason for doing B’ means ‘A is a (...) reason an agent ought to do B’. So, it is advisable to schematize that kind of statements as ‘’, where ‘OB’ is a deontic statement prescribing the duty to do B. Reasons of type have a descriptive sense and do not require the above-mentioned constraint. But ‘being a reason for’ has different senses according to context, even when the distinction between justificative and explicative reasons is drawn. Accordingly, it is important to distinguish two basic types of reasons: sufficient and necessary, and two subordinate types of reasons: contributing and substitutive . A lot of attention has been paid, lately, to a sense of contributive reasons: prima facie reasons . The paper will deal with that kind of reasons. Its main thesis are: 1) prima facie reason-statements are defeasible conditionals ‘’ pointing out that A is a contributing condition of B, 2) a defeasible conditional has the properties of ‘’, where ‘ =>’ is a strict implication and ‘f’’ a revision-operator satisfying the conditions set up by the theory AGM on the rational change of theories.
