El presente artículo trata de superar la división entre una epistemología de virtudes confiabilista y otra responsabilista. En su lugar se presenta una visión orgánica del conocimiento humano. La visión orgánica –también denominada pre-cismática- articula aspectos confiabilistas y responsabilistas. Finalmente se discute un nuevo concepto: felicidad epistémica, que se justifica desde la perspectiva agentiva del conocimiento. Así, se sostiene que parece razonable pensar que el conocimiento es un tipo de acción cuyo fin último es la felicidad. Esta felicidad se puede (...) obtener por vía negativa –al no obtener una verdad pero sí una mejora de la situación epistémica- o por vía positiva, esto es, cuando se da en el blanco de la verdad.

RESUMENEl presente artículo analiza las diferentes teorías que sobre el concepto de función se han vertido en los últimos cuarenta años y sus problemas. Respecto de los dos grandes enfoques (histórico-etiológico y sistémico) se sostiene que el primero, pese a su hegemonía histórica, presenta considerables dificultades y que la reflexión actual se centra cada vez más en la perspectiva sistémica. Esta última puede enfrentarse mejor a los diversos problemas que genera el concepto de función biológica y es siempre preferible.PALABRAS CLAVEFUNCIÓN (...)

Teleosemantic theories of content constitute a mixed family of different proposals and accounts about what consists mental content. In the present paper, I would like examine the scope and limits of a particular and well defined teleosemantic theory such as Millikan’s account. My aim entails presenting arguments in order to show how her theory of mental content is unnable of giving a complete account of the whole mental life almost for adult human agents without commiting certain adaptationist assumptions. I am (...) going to present my arguments in the following order. In section 1 I present an outline of the Millikan’s theory of mental content. In section 2, after defining useless content I pay attention to her treatment of it. In section 3 I set out my queries concerning to the fixation of useless content defended by Millikan. Finally, I conclude that the theory about useless content doesn’t identify content in terms of sufficient and necessary conditions. (shrink)

Having analyzed the formal aspects of Wallace’s proof of the Born rule, we now discuss the concepts and axioms upon which it is built. Justification for most axioms is shown to be problematic, and at times contradictory. Some of the problems are caused by ambiguities in the concepts used. We conclude the axioms are not reasonable enough to be taken as mandates of rationality in Everettian Quantum Mechanics. This invalidates the interpretation of Wallace’s result as meaning it would be rational (...) for Everettian agents to decide using the Born rule. (shrink)

To solve the probability problem of the Many Worlds Interpretation of Quantum Mechanics, D. Wallace has presented a formal proof of the Born rule via decision theory, as proposed by D. Deutsch. The idea is to get subjective probabilities from rational decisions related to quantum measurements, showing the non-probabilistic parts of the quantum formalism, plus some rational constraints, ensure the squared modulus of quantum amplitudes play the role of such probabilities. We provide a new presentation of Wallace’s proof, reorganized to (...) simplify some arguments, and analyze it from a formal perspective. Similarities with classical decision theory are made explicit, to clarify its structure and main ideas. A simpler notation is used, and details are filled in, making it easier to follow and verify. Some problems have been identified, and we suggest possible corrections. (shrink)

This paper is part of a series in which we had worked in the last 6 months, and, specifically, intend to investigate the notion of timbre through the ecological perspective proposed by James Gibson in his Theory of Direct Perception. First of all, we discussed the traditional approach to timbre, mainly as developed in acoustics and psychoacoustics. Later, we proposed a new conception of timbre that was born in concepts of ecological approach. The ecological approach to perception proposed by Gibson (...) (1966, 1979) presupposes a level of analysis of perceptual stimulated that includes, but is quite broader than the usual physical aspect. Gibson suggests as focus the relationship between the perceiver and his environment. At the core of this approach, is the notion of affordances, invariant combinations of properties at the ecological level, taken with reference to the anatomy and action systems of species or individual, and also with reference to its biological and social needs. Objects and events are understood as relates to a perceiving organism by the meaning of structured information, thus affording possibilities of action by the organism. Event perception aims at identifying properties of events to specify changes of the environment that are relevant to the organism. The perception of form is understood as a special instance of event perception, which is the identity of an object depends on the nature of the events in which is involved and what remains invariant over time. From this perspective, perception is not in any sense created by the brain, but is a part of the world where information can be found. Consequently, an ecological approach represents a form of direct realism that opposes the indirect realist based on predominant approaches to perception borrowed from psychoacoustics and computational approach.

Background and ObjectivesUp to 10% of fathers experience perinatal depression, often accompanied by anxiety, with a detrimental impact on the emotional and behavioural development of infants. Yet, few evidence-based interventions specifically for paternal perinatal depression or anxiety exist, and few depressed or anxious fathers engage with support. This mini-review aims to build on the evidence base set by other recent systematic reviews by synthesising more recently available studies on interventions for paternal perinatal depression and anxiety. Secondarily, we also aimed to (...) identify useful information on key implementation strategies, if any, that increase the engagement of men.MethodsWe drew upon three major previous systematic reviews and performed an updated search of PubMed/Medline; Psycinfo; Cochrane Database; Embase and Cinahl. The search was limited to trials, feasibility studies or pilot studies of interventions published between 2015 and 2020 that reported on fathers' perinatal mental health. We included psychological, educational, psychosocial, paternal, couple-focused, or group therapies, delivered face-to-face, via telephone and/or online that reported on either paternal depression, anxiety or both.ResultsEleven studies satisfied search criteria. The majority were randomised controlled trials. Most interventions incorporated counselling, therapy or psychoeducation and took an indirect approach to perinatal mental health through antenatal or postnatal education and were couple-focused. No studies reported a presence of diagnosed depression or anxiety at baseline, although five studies reported a positive effect on sub-threshold symptoms.DiscussionThere was some evidence that these approaches may be useful in the initial engagement of fathers with perinatal supports and improve depression and anxiety scores. No studies targeted the explicit treatment of clinically depressed or anxious men, and this remains the most substantial gap in the peer-reviewed evidence base. Our results highlight the need to deliver perinatal interventions specifically designed for men and evaluate them in populations with clinical levels of depressive and anxious symptomatology.

Elefantes y linternas: sobre Martin sobre Raz El ensayo responde a algunas de las críticas de Margaret Martin a la teoría jurídica de Joseph Raz, en su libro Judging Positivism, especialmente la alegación de que Raz cambió su teoría de la aplicación del derecho y de que este cambio produjo un impacto negativo en la teoría del derecho de Raz. Para fornecer estas respuestas, se adopta una perspectiva que trata las teorías jurídicas como análisis hipotéticos que buscan comprender el derecho (...) exclusivamente bajo un entre múltiplos aspectos, ignorando los demás. De modo comparable con los planteamientos de ciegos que tocan un elefante en una conocida parábola indiana, se adopta una metáfora de una lanterna con la cual el elefante es examinado en cada teoría.

Reestablishing feelings of control after experiencing uncertainty has long been considered a fundamental motive for human behavior. We propose that rituals (i.e., socially stipulated, causally opaque practices) provide a means for coping with the aversive feelings associated with randomness due to the perception of a connection between ritual action and a desired outcome. Two experiments were conducted (one in Brazil [n = 40] and another in the United States [n = 94]) to evaluate how the perceived efficacy of rituals is (...) affected by feelings of randomness. In a between-subjects design, the Scramble Sentence Task was used as a priming procedure in three conditions (i.e., randomness, negativity, and neutral) and participants were then asked to rate the efficacy of rituals used for problem-solving purposes. The results demonstrate that priming randomness increased participants' perception of ritual efficacy relative to negativity and neutral conditions. Implications for increasing our understanding of the relationship between perceived control and ritualistic behavior are discussed. (shrink)

In their commentaries on Peter of Spain’s texts, two professors at the University of Cracow, John of Glogovia and Michael of Biestrzykowa, provided interpretations of consequences and conditional propositions which either rejected the paradoxes of strict implication or placed on them such restrictions as to challenge traditional views about the relation between antecedent and consequent. Nicholas Copernicus may have been inflenced by those discussions.

En primer lugar, se subraya el valor e interés filosófico de la obra de Comenius y se relaciona con la problemática intelectual y filosófica de su momento. En segundo lugar, se procede a un análisis del texto destacando su concepción antropológica y la dependencia de una determinada concepción metafísica para el desarrollo de sus ideas epistemológicas. En tercer lugar, se analiza la pansofía como (...) logro metafísico y epistemológico de Comenius. Finalmente, se concluye con un análisis acerca del método presente en el proyecto epistemológico elaborado en el Prodromus. (shrink)

RESUMEN La teleosemántica es el intento de naturalizar el contenido mental mediante el recurso al concepto de función biológica. En el presente artículo se argumenta que la teleosemántica carece de los recursos necesarios para hacer frente a tres problemas: la indeterminación del contenido, el carácter abstracto de este y la inutilidad biológica de algunas de las representaciones que pueden albergar organismos como los humanos. ABSTRACT Teleosemantics is the attempt to naturalize mental content by resorting to the concept of biological function. (...) The article argues that teleosemantics lacks the necessary resources to solve three problems: the indeterminacy of content, its abstract nature, and the biological uselessness of some of the representations of certain organisms such as human beings.

This is a review of Kazutaka Inamura's book "Justice and Reciprocity in Aristotle's Political Philosophy" (Cambridge University Press, 2017).

In 1993, investigators from George Washington University Medical Center separated the cells of 17 human embryos and produced 48 embryos, an average of three embryos for each original. The method, variously called twinning, cloning, embryo splitting, and blastomere separation, demonstrated that human embryos could be split to create genetically identical entities during conception. When publicized, however, the experiment brought to mind a different view of cloning repeated since the beginning of the new reproductive technologies. In the early 1970s, when research (...) on in vitro fertilization was in its infancy, commentators worried that cloning–defined as the duplication of persons–would be next, leading to a scenario of “boys genetically exactly like the father, girls like the mother, or individuals like some true or false hero of art, science, or sports, or like some demagogue or some saint.”.

A scientist at Edinburgh University announced in 1994 that he had removed ovaries from, mouse fetuses and transplanted them, to adult mice. The ovaries released eggs, and conceptions occurred. Although this was not the first such attempt with mice, the study attracted attention because the researcher suggested, that fetal to adult ovarian transplants were a theoretical possibility for humans. If aborted, fetuses were used, as egg sources in assisted conception, a new entity would arise: the never-born genetic mother. Using eggs (...) from aborted fetuses for conception would lead to quixotic and novel family ties. Its use would echo surrogate gestational motherhood, in which a child has both a genetic mother who contributed her egg and a gestational mother who contributed her uterus for gestation and childbirth. With fetal egg use, however, the child's genetic mother would be a never-born fetus without sentience or known, physiology. (shrink)

To clone humans is deliberately to generate two or more individuals who share the same nuclear deoxyribonucleic acid. Using animals, researchers have performed two basic types of cloning that will eventually yield commercial benefits. Embryo twinning involves separating the individual cells of an embryo and allowing each to cleave for later transfer to a uterus. Cloning by nuclear transfer involves removing the nuclei from embryonic cells or fetal or adult somatic cells and fusing those nuclei with enucleated donor egg cells. (...) Although for the purposes of commercial biotechnology these techniques do not raise undue concern when attempted with animals, embryo twinning, embryo nuclear transfer, fetal somatic cell nuclear transfer, and adult somatic cell nuclear transfer all provoke intense ethical discussions when considered for human use.

As increasing numbers of infertility clinics in the U.S. offer embryo freezing as part of their IVF protocols, public debate on its ethical implications has calmed. Yet in clinical settings, unanswered questions suggest the need to keep alive the ethical debate about the benefits to patients and society of embryo freezing.

Plagiarism is a serious, yet widespread type of research misconduct, and is often neglected in developing countries. Despite its far-reaching implications, plagiarism is poorly acknowledged and discussed in the academic setting, and insufficient evidence exists in Latin America and developing countries to inform the development of preventive strategies. In this context, we present a longitudinal case study of seven instances of plagiarism and cheating arising in four consecutive classes of an Epidemiology Masters program in Lima, Peru, and describes the implementation (...) and outcomes of a multifaceted, “zero-tolerance” policy aimed at introducing research integrity. Two cases involved cheating in graded assignments, and five cases correspond to plagiarism in the thesis protocol. Cases revealed poor awareness of high tolerance to plagiarism, poor academic performance, and widespread writing deficiencies, compensated with patchwriting and copy-pasting. Depending on the events’ severity, penalties included course failure and separation from the program. Students at fault did not engage in further plagiarism. Between 2011 and 2013, the Masters program sequentially introduced a preventive policy consisting of: intensified research integrity and scientific writing education, a stepwise, cumulative writing process; honor codes; active search for plagiarism in all academic products; and a “zero-tolerance” policy in response to documented cases. No cases were detected in 2014. In conclusion, plagiarism seems to be widespread in resource-limited settings and a greater response with educational and zero-tolerance components is needed to prevent it. (shrink)

The T lymphocyte receptor for antigen, which operates in conjunction with gene products of the major histocompatibility complex (MHC), is a molecular complex comprised of five polypeptide chains. Both the 49 kDa alpha and 43 kDa beta chains are immunoglobulin‐like and thus contain variable domains responsible for ligand binding. In contrast, the 20–25 kDa T3 gamma, delta and epsilon chains are monomorphic structures presumably involved in transmembrane signalling. The alpha and beta subunits are disulfide bonded to each other and held (...) in noncovalent association with the T3 chains. T3‐Ti receptor crosslinking leads to conformational modification of a second T lineage specific molecule, termed the 50 kDa T11 structure which in turn leads to protein kinase C activation, elevation in intracytoplasmic free calcium and Na+/H+ antiport stimulation.

Løgstrups hovedværk fra 1956 med nyt efterskrift ved Hans Fink. “Så vist som et menneske med den tillid, det viser eller begærer, giver mer eller mindre af sit liv i den andens hånd, så vist hører fordringen om at tage vare på det liv med til vor tilværelse sådan som den nu engang er. Hvor meget eller hvor lidt der står på spil for et menneske i den tillid, det viser, er selvsagt uhyre forskelligt. Det beror på mange forskellige faktorer, (...) på den enkeltes psykiske konstitution og øjeblikkelige befindende, på situationen, der ikke mindst er bestemt af, hvem og hvordan den anden er. Men hvorom alting er, betyder det, at der i et hvilket som helst møde mellem mennesker ligger en uudtalt fordring, uanset under hvilke omstændigheder mødet finder sted og hvilken karakter det har.” "Klassiker. Hvis man tror, at Løgstrups etiske fordring er et pladderhumanistisk budskab om næstekærlighed og at »tage vare på hinanden«, så er genudgivelsen en passende lejlighed til at få den læst. (...) Løgstrups fænomenologiske analyser af forholdet mellem mennesker og af vore selvbedrageriske bortforklaringer af vore egne reaktioner på andre er stadig dugfriske, som var de skrevet i går."
