Significant associations have been found between specific human leukocyte antigen (HLA) alleles and organ transplant rejection, autoimmune disease development, and the response to infection. Traditional searches for disease associations have conventionally measured risk associated with the presence of individual HLA alleles. However, given the high level of HLA polymorphism, the pattern of amino acid variability, and the fact that most of the HLA variation occurs at functionally important sites, it may be that a combination of variable amino acid sites shared (...) by several alleles (shared epitopes) are better descriptors of the actual causative genetic variants. Here we describe a novel approach to genetic association analysis in which genes/proteins are broken down into smaller sequence features and then variant types defined for each feature, allowing for independent analysis of disease association with each sequence feature variant type. We have used this approach to analyze a cohort of systemic sclerosis patients and show that a sequence feature composed of specific amino acid residues in peptide binding pockets 4 and 7 of HLA-DRB1 explains much of the molecular determinant of risk for systemic sclerosis.

Four studies explore the role of perceptual fluency in attenuating bullshit receptivity, or the tendency for individuals to rate otherwise meaningless statements as “profound”. Across four studies, we presented participants with a sample of pseudoprofound bullshit statements in either a fluent or disfluent font and found that overall, disfluency attenuated bullshit receptivity while also finding little evidence that this effect was moderated by cognitive thinking style. In all studies, we measured participants’ cognitive reflection, need for cognition, faith in intuition, and (...) superstitious beliefs. Superstition strongly predicted bullshit receptivity regardless of fluency. Inconclusive results were found for the remaining scales. Potential links for the role of perceptual disfluency in promoting analytic thinking are discussed. (shrink)

Worsening energy crises and the growing effects of climate change have spurred, among other things, concerted efforts to tackle global problems through what the United Nations calls Sustainable Development Goals (SDGs). These are in turn argued to be best achieved via the adoption of environmental, social, and corporate governance (ESG) as the vehicle for guiding our efforts. However, though these things are often presented as the solution to global issues, they are increasingly being used as a means to centralize power (...) and exacerbate growing authoritarian trends. This article aims to demonstrate how the narratives surrounding ESG mask this reality, taking as a solution one of the foundational causes of global wealth and power disparity. (shrink)

In this study, screening positive for probable depression was common among undergraduate students at the University of the Witwatersrand, Johannesburg, South Africa and associated with sociodemographic and selected behavioral factors. These findings call for strengthening the awareness and use of counselling services among undergraduate students.

The potential for vaccines to prevent the spread of infectious diseases is crucial for vaccination policy and ethics. In this paper, I discuss recent evidence that the current COVID-19 vaccines have only a modest and short-lived effect on reducing SARS-CoV-2 transmission and argue that this has at least four important ethical implications. First, getting vaccinated against COVID-19 should be seen primarily as a self-protective choice for individuals. Second, moral condemnation of unvaccinated people for causing direct harm to others is unjustified. (...) Third, the case for a harm-based moral obligation to get vaccinated against COVID-19 is weak. Finally, and perhaps most significantly, coercive COVID-19 vaccination policies (e.g., measures that exclude unvaccinated people from society) cannot be directly justified by the harm principle.

This review article provides a brief descriptive overview of past efforts to use self-referential argumentation, distinguishing pragmatical from metalogical self-referential approaches. The reviewer claims that the pragmatical self-referential argument proposed in this book is itself metalogically self-referentially inconsistent, and directs the reader to other relevant published works by the reviewer.

The repugnant conclusion poses a conundrum in population ethics that has evaded satisfactory solution for four decades. In this article, I show that the repugnant conclusion can be avoided without sacrificing any moral intuitions. The resulting framework satisfies Parfit's requirements for `theory X'. This is achieved using non-Archimedean orders, which admit the possibility of pairs of goods for which no amount of one is better than a single unit of the other. I show that with minimal assumptions, not only are (...) such goods sensible, they are compulsory. I show that utilitarianism and expected utility theory in their canonical forms are not in general suitable in this setting, and using these tools naively can lead to ethical errors that are arbitrarily serious. Multi-dimensional lexicographic expected utility representations may be required. I use fuzzy sets to show that there needn't be a clear boundary separating goods that are not Archimedean equivalent. This may be unavoidable due to intrinsic physical limits on the ability to discriminate between different goods arising from e.g. quantum mechanics. Limited discriminatory power causes preferences to be non-transitive, which can resolve problems related to so-called `fanaticism' and `recklessness' wherein `rational' decision-makers counterintuitively prefer arbitrary long shot bets to a guaranteed lesser outcome.

The rapid expansion of Big Tech companies into various societal domains (e.g., health, education, and agriculture) over the past decade has led to increasing concerns among governments, regulators, scholars, and civil society. While existing theoretical frameworks—often revolving around privacy and data protection, or market and platform power—have shed light on important aspects of Big Tech expansionism, there are other risks that these frameworks cannot fully capture. In response, this editorial proposes an alternative theoretical framework based on the notion of sphere (...) transgressions, which draws on political philosopher Michael Walzer's theory of justice. The editorial not only introduces the sphere transgressions framework, but it also highlights its potential to generate novel research questions. Furthermore, this editorial introduces eight articles and one commentary from a group of interdisciplinary scholars that critically examine Big Tech expansionism by reflecting on this expansionism from the perspective of different societal spheres or by engaging with the sphere transgressions framework itself.

Onychectomy involves the surgical amputation of a cat's claws. Tendonectomy entails surgically cutting tendons to prevent the extension and full use of a cat's claws. Both surgeries practically declaw cats and are not only painful but also associated with high complication rates. While feline declawing surgeries have been banned in various places around the world, they are still elective in many countries and U.S. states. This article provides an ethical analysis of declawing cats. It discusses the harms posed by feline (...) declawing surgeries, like pain and complications, which are not offset by any benefits to cats. Drawing on Martha Nussbaum's capabilities approach, it also offers an additional and broader ethical argument against declawing, namely that removing cats' claws is unjust because it thwarts important capabilities for feline flourishing (e.g., play, bodily integrity, control over one's environment). It concludes that declawing cats for non-medical purposes is unethical and must be opposed. (shrink)

A book review of _Free Choice: A Self-referential Argument_ by J. M. Boyle, Jr., G. Grisez, and O. Tollefsen. The review concerns the pragmatical self-referential argument employed in the book, and points to the fact that the argument is itself self-referentially inconsistent, but on the level of metalogical self-reference.

Arguably the biggest challenge in analyzing English tense is to account for the double access interpretation, which arises when a present tensed verb is embedded under a past attitude—e.g., "John said that Mary is pregnant". Present-under-past does not always result in a felicitous utterance, however—cf. "John believed that Mary is pregnant". While such oddity has been noted, the contrast has never been explained. In fact, English grammars and manuals generally prohibit present-under-past. Work on double access, on the other hand, has (...) either disregarded the oddity (e.g., Abusch 1997: 39) or treated it as a reflex of a particular dialect (e.g., Kratzer 1998: 14). The goal of the paper is to argue—based on a corpus study—that a present-under-past sentence is grammatical, but modulated by two, interacting pragmatic phenomena: cessation and parentheticality.

Contemporary discussions about operational definition often hark back to Stanley Smith Stevens’ classic papers on psychological operationism (1935ab). Still, he was far from the only psychologist to call for conceptual hygiene. Some of Stevens’ direct colleagues at Harvard---most notably B. F. Skinner and E. G. Boring---were also actively applying Bridgman’s conceptual strictures to the study of mind and behavior. In this paper, I shed new light on the history of operationism by reconstructing the Harvard debates about operational definition in the (...) years before Stevens published his seminal articles. Building on a large set of archival evidence from the Harvard University Archives, I argue that we can get a more complete understanding of Stevens’ contributions if we better grasp the operationisms of his former teachers and direct colleagues at Harvard’s Department of Philosophy and Psychology.

I start with some famous comments by the philosopher (psychologist) Ludwig Wittgenstein because Pinker shares with most people (due to the default settings of our evolved innate psychology) certain prejudices about the functioning of the mind and because Wittgenstein offers unique and profound insights into the workings of language, thought and reality (which he viewed as more or less coextensive) not found anywhere else. The last quote is the only reference Pinker makes to Wittgenstein in this volume, which is most (...) unfortunate considering that he was one of the most brilliant and original analysts of language. -/- In the last chapter, using the famous metaphor of Plato’s cave, he beautifully summarizes the book with an overview of how the mind (language, thought, intentional psychology) –a product of blind selfishness, moderated only slightly by automated altruism for close relatives carrying copies of our genes--works automatically, but tries to end on an upbeat note by giving us hope that we can nevertheless employ its vast capabilities to cooperate and make the world a decent place to live. -/- Pinker is certainly aware of but says little about the fact that far more about our psychology is left out than included. Among windows into human nature that are left out or given minimal attention are math and geometry, music and sounds, images, events and causality, ontology (classes of things), dispositions (believing, thinking, judging, intending etc) and the rest of intentional psychology of action, neurotransmitters and entheogens, spiritual states (e.g, satori and enlightenment, brain stimulation and recording, brain damage and behavioral deficits and disorders, games and sports, decision theory (incl. game theory and behavioral economics), animal behavior (very little language but a billion years of shared genetics). Many books have been written about each of these areas of intentional psychology. The data in this book are descriptions, not explanations that show why our brains do it this way or how it is done. How do we know to use the sentences in their various way (i.e., know all their meanings)? This is evolutionary psychology that operates at a more basic level –the level where Wittgenstein is most active. And there is scant attention to context. -/- Nevertheless this is a classic work and with these cautions is still well worth reading. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019).

_La Peste_, originally published in 1947 by the Nobel Prize-winning writer Albert Camus, chronicles the progression of deadly bubonic plague as it spreads through the quarantined Algerian city of Oran. While most discussions of fictional examples within aesthetics are either historical or hypothetical, Camus offers an example of "pestilence fiction." Camus chose fiction to convey facts--about plagues in the past, his own bout with tuberculosis at age seventeen, living under quarantine away from home for several years, and forced separation from (...) his wife who remained in Algiers while he was abroad in Nazi-occupied France. His own lived experiences undergird an imaginative account of shared human realities with which we can identify: vulnerability to the disease, isolation, fear, and finally humanitarianism. _The Plague_ teaches us to neither covet nor expect what we so casually took for granted. This collection of original essays on philosophical themes in _The Plague_ is of special relevance during and in the aftermath of Covid-19 but also provides reflections that will be of lasting value to those interested in this classic work of literature. The novel explores questions of enduring importance. Do we collectively meet the threshold of ethical behavior posed by Camus who wrote, "What's true of all the evils in the world is true of plague as well. It helps men to rise above themselves"? Or does the absurd undermine the compassionate? Do "heroes" dutifully fight a plague with "common decency," or does human nature resign itself to the normalization of uncontrollable suffering and death? There are myriad ways to approach the novel and this volume encourages readers to ponder human dilemmas in fictional Oran informed by our current pandemic. Series editor forward by Richard Eldridge.

● Any given placement (e.g. Sun in Taurus; Mars in Capricorn; Mercury in the third house) is necessarily common to tens of thousands of people. Saturn in the ninth house, for example, will not behave the same or produce the same effects in the twenty or one hundred charts in which we find it there. In each case Saturn will behave in accordance with the rest of the astrographic/chart composition (as if we stayed in the same hotel in different epochs (...) or different people contracted the same disease; our stay will be different each time, according to the epoch, and each person’s symptoms will too, be different, according to their individual biochemistry; not to mention that each chart or astrography, like each genetic code or sequence, is unrepeatable). Certainly, “no planet can produce, on its own, what only the combined or concerted action of all can” (BUSTAMANTE, 2023, SPICA magazine, pp. 93-111). Hence the synergistic nature of the interpretative exercise (i.e., the whole is greater than all its parts). The fundamental component of the mathematical expression of the interpretive exercise is: astrological triangulation, the functional denomination for what we know as synthesis (WEISS, 1946; LEO, 1983, HAND, 1981). In order to demonstrate its usefulness, as well as the convenience of its mathematical expression, we have chosen two individuals (JEFFREY DAHMER, STEVEN SPIELBERG) whose astrographies do not—according to the community—explain their lives. The rest of the astrographies correspond to those of serial killers JOHN WAYNE GACY, DAVID CARPENTER, and TED BUNDY. ● We explain, by means of algebraic notations, the synthesis and the functional values that make up the synthesis. ● We take the Moon and Neptune as relevant bodies for the purpose of diagnosing or studying endocrine or neurohormonal issues, and Mars, Pluto, and Saturn as relevant planets for the purpose of inferring violence or sinister behaviour, upon the case, and quadratures or oppositions—and conjunctions—between Venus and the Moon, the Moon and Neptune, and the Sun or Venus and Neptune or Uranus as indicators of neurohormonal disorders and/or sexual deviance (APA definition) . ● We consider quadratures (90º) or oppositions (180º)—and conjunctions—between Mercury or the Moon and Saturn, or between Mars or the Moon and Saturn, Uranus, Neptune, and/or Pluto as powerful indications of violence or mental disorders, upon the case. ● We have also regarded Sagittarius as a sign as expansive and abundant as its ruler, Jupiter, according to the best of its characterisations (or as an exceptionally swift and wild sign, according to other characterisations), and the fifth region of a natal chart as one closely related to fortune in a broad sense (material and immaterial). ● Because we advocate the idea that orbs should be predicated of the planet (size, speed), not the aspect itself, the gas giants (Jupiter, Saturn, Uranus, and Neptune) and the Sun have been granted up to 10º of orb (or 12º, in the case of broad influence ). We understand aspectual relationships as angular relationships held between two or more celestial bodies placed in signs with at least one property in common (according to our molecular theory of the ecliptic, compatible with the optical theory of the aspects from the Hellenistic tradition).

Though the concepts of diversity and inclusion are still widely used in the contexts of management, policy-making, and academic research, the notion of superdiversity is becoming increasingly popular. First articulated by social anthropologist Steven Vertovec (see Vertovec, 2006; 2007; 2012), superdiversity has been described as a concept and theoretical tool that enables us to study our ever-evolving, globalising social reality in great detail by taking the enormous amount of diversity that exists within different groups in societies around the world (...) into account as well, in addition to differences between different groups. Superdiversity is mainly linked to the growing ethnic and cultural complexity of Western European societies, and is therefore often associated with the rise of so-called majority-minority- cities, such as Amsterdam, Brussels, and London, to name a few – all cities in which ethnic minority groups are about to replace (or have already replaced) the ethnic majority group (see, e.g., Crul, Schneider, & Lelie, 2013; Crul, 2016; Geldof, 2015).

With An Answer to the Question: What Is Enlightenment? (1784) and What Does It Mean to Orient Oneself in Thinking? (1786), Kant presents the concept of public use of reason and defines its requirements, scope, and function. In outline, the public use of reason consists in sharing one’s thoughts with “the entire public of the world of readers” (8:37). As for its requirements, to the extent that someone communicates in their own person, i.e. not in the exercise of their function (...) as a public official, and bases their reasoning on universalizable grounds, their use of reason qualifies as public and shall be free from state censorship. Therefore, Kant’s concept of public use reason aims to establish a public debate that is free and includes in its scope, both as subjects and recipients, potentially all adult men. The ultimate function of the public use of reason is to foster moral progress and, with it, the reform of the political community according to the republican ideal. However, it is commonly held that Kant, with his 1798 essay The Conflict of the Faculties, deprives his notion of public use of reason of its progressive core and adjusts it to the absolutist conception of speech and civil service. Characterizations of state officials as “not free to make public use of their learning” (7:18) and “bound to uphold whatever […] the crown sanctions for them to expound publicly” (7:8), as well as the depiction of laypeople as “incompetent” (7:18) and “resigned to understanding nothing about [the sciences]” (7:34), have led influential interpreters to read Kant as redefining his notion of public use of reason by restricting its subjects to university professors and its recipients to government members (e.g. John Christian Laursen 1986, rpt. 1992 and 1996; Kevin Davis 1992; Steven Lestition 1993; Jay Franzel 2013). On my reading, with The Conflict of the Faculties, Kant does indeed redefine the concept of public use of reason making concessions to the absolutist notion of speech and civil service. However, a close reading of the text reveals that the public use of reason ends up being reaffirmed in its progressive core and extended in its scope. To substantiate my interpretation, I will systematically analyse and classify each of the 68 occurrences of the adjective ‘public’ in The Conflict of the Faculties and show how Kant employs the absolutist vocabulary to convey the progressive project of his previous writings. Accordingly, I argue that Kant holds on to the free public use of reason as a means to reform politics according to the republican ideal and that the employment of the absolutist vocabulary is motivated by a pragmatic attitude and a provocative stance.

Though this volume is a bit dated, there are few recent popular books dealing specifically with the psychology of murder and it’s a quick overview available for a few dollars, so still well worth the effort. It makes no attempt to be comprehensive and is somewhat superficial in places, with the reader expected to fill in the blanks from his many other books and the vast literature on violence. For an update see e.g., Buss, The Handbook of Evolutionary Psychology 2nd (...) ed. V1 (2016) p 265, 266, 270–282, 388–389, 545–546, 547, 566 and Buss, Evolutionary Psychology 5th ed. (2015) p 26, 96–97,223, 293-4, 300, 309–312, 410 and Shackelford and Hansen, The Evolution of Violence (2014) He has been among the top evolutionary psychologists for several decades and covers a wide range of behavior in his works, but here he concentrates almost entirely on the psychological mechanisms that cause individual people to murder and their possible evolutionary function in the EEA (Environment of Evolutionary Adaptation—i.e., the plains of Africa during the last million years or so). -/- Buss starts by noting that as with other behaviors, ‘alternative’ explanations such as psychopathology, jealousy, social environment, group pressures, drugs and alcohol etc. do not really explain, since the question still remains as to why these produce homicidal impulses, i.e., they are the proximate causes and not the ultimate evolutionary (genetic) ones. As always, it inevitably boils down to inclusive fitness (kin selection), and so to the struggle for access to mates and resources, which is the ultimate explanation for all behavior in all organisms. Sociological data (and common sense) make it clear that younger poorer males are the most likely to kill. He presents his own and others homicide data from industrialized nations, and tribal cultures, conspecific killing in animals, archeology, FBI data and his own research into normal people's homicidal fantasies. Much archeological evidence continues to accumulate of murders, including that of whole groups, or of groups minus young females, in prehistoric times. -/- After surveying Buss’s comments, I present a very brief summary of intentional psychology (the logical structure of rationality), which is covered extensively in my many other articles and books. -/- Those with a lot of time who want a detailed history of homicidal violence from an evolutionary perspective may consult Steven Pinker’s ‘The Better Angels of Our Nature Why Violence Has Declined’(2012), and my review of it easily available on the net and in two of my recent ebooks. Briefly, Pinker notes that murder has decreased steadily and dramatically by a factor of about 30 since our days as foragers. So, even though guns now make it extremely easy for anyone to kill, homicide is much less common. Pinker thinks this is due to various social mechanisms that bring out our ‘better angels’, but I think it’s due mainly to the temporary abundance of resources from the merciless rape of our planet, coupled with increased police presence, with communication and surveillance and legal systems that make it far more likely to be punished. This becomes clear every time there is even a brief and local absence of the police. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems of thought viewpoint may consult my e-book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Wittgenstein and Searle 367p (2016).

NUTRIÇÃO SOBRE A AZOOSPERMIA EM BOVINOS -/- -/- E. I. C. da Silva Departamento de Agropecuária – IFPE Campus Belo Jardim Departamento de Zootecnia – UFRPE sede -/- AZOOSPERMIA EM BOVINOS -/- INTRODUÇÃO -/- A falta completa de esperma no ejaculado pode ser devido a uma falha no processo de espermatogênese ou relacionada a causas no transporte do esperma. Com relação ao transporte, o esperma pode ser impedido de ser ejaculado mediante bloqueios ou oclusões no sistema do ducto extragonadal, ou (...) por causa de uma disfunção ejaculatória. Nos cães, por exemplo, a possibilidade de oclusão ser a causa pode ser determinada por medições de fosfatase alcalina (ALP) no plasma seminal, já que a ALP se origina do epidídimo e seminífero epitélio tubular. Se a concentração de ALP no fluido seminal for superior a 5000 UI/l, a amostra ejaculada contém fluido desses tecidos e a oclusão pode ser descartada. -/- As causas testiculares da azoospermia incluem a falha da espermatogênese, que pode ser causada por uma série de fatores; estes incluem fatores hormonais, imunológicos, congênitos, tóxicos, patogênicos, traumáticos e nutricionais. Aqui, as supressões na região do AZF (que contém sub-regiões AZFa, AZFb e AZFc) no cromossoma Y desempenham um papel importante, representando 10-15% dos casos de azoo- e oligospermia. Na região AFZc, o gene DAZ, que é suprimido na azoospermia, é considerado importante no controle espermatogênico, uma vez que a sua eliminação é frequentemente detectada em homens e/ou animais inférteis. -/- A perda total da capacidade de formação de espermatozoides pelo epitélio testicular e, portanto, a ausência de espermatozoides viáveis ou não no volume ejaculado pelo animal é denominado como azoospermia (VARNER et al., 2000), um macho nessas condições deve ser imediatamente retirado dos processos produtivos e não é, de forma alguma, viável para fins reprodutivos. A origem da causa pode ter caráter nutricional, ou outras, sendo multifatoriais; em processos crônicos severos pode-se chegar à azoospermia reversível, que é diagnosticada e corrigida de forma oportuna. Entre os principais fatores de caráter nutricional temos: -/- 18.1 Nitratos (NO3-) e nitritos (NO2-) -/- Quando os ruminantes consomem uma alimentação com elevadas concentrações de nitratos (presente principalmente nas forrageiras) parte do nitrato não pode ser imediatamente convertido em nitrito e, por fim, em amoníaco (todas essas transformações acontecem no rúmen mediante a flora microbiana); isso faz com que nitrato e nitrito se acumulem no rúmen. A adição do nitrato no rúmen intensifica o problema. O envenenamento por nitrato ocorre quando o nível de nitrito presente no rúmen excede a capacidade do microbiota para convertê-lo em amoníaco. Quando isto acontece, o nitrato e o nitrito são absorvidos através da parede do rúmen e entram na circulação sanguínea. É o nitrito que causa a toxicidade. -/- Estudou-se o equilíbrio ácido-básico e sua relação com a reprodução e produção, postulando a hipótese de que esse equilíbrio afeta os mecanismos endócrinos e metabólicos, além dos reprodutivos. -/- 18.2 Relação energia:proteína -/- Quando a alimentação apresenta deficiências de energia aumenta-se a degradação das gorduras (provenientes do tecido adiposo), acompanhada pela redução da liberação de insulina (hipoinsulinemia) afetando-se a lipogênese, mobilizando-se mais gordura corporal do que se sintetiza. -/- Situações como a acidose ruminal (excesso de grão e deficiência em fibras) ou alcalose ruminal (excesso de ureia com baixa energia digerível) resultam em perturbações sobre a fertilidade; além disso, deficiências energéticas graves que levam à cetose causam estresse com a liberação de catecolaminas, ACTH e TSH que afetam a secreção de GnRH, afetando por fim, a espermiogênese. -/- -/- Uma diminuição de energia na alimentação gera hipoglicemia que, ao mesmo tempo, produz hipoinsulinemia incrementando assim a lipólise em tecidos, gerando como produtos as cetonas. -/- A hipoinsulinemia juntamente com a cetonemia e a geração de beta-endorfinas, por problemas na alimentação, reduzem notavelmente a síntese de GnRH. A GnRH reduz a liberação do LH e FSH. A diminuição da liberação do LH provoca azoospermia hipogonadotrópica com efeitos de estimulação hormonal anormais segundo a avaliação endócrina, bem como a obstrução testicular inexplicada. -/- Se houver um aumento significativo na liberação de FSH, a azoospermia hipogonadotrópica é refletida em diagnóstico como disfunção testicular. -/- 18.3 Minerais (Selênio Se) -/- Quando os níveis de Se na dieta são deficientes, ocorrem falhas na formação e maturação espermática. O Se mostra uma grande influência na fertilidade do macho afetando a qualidade do sêmen, o plasma seminal contém elevadas quantidades de GSH-Px, cuja função é proteger a membrana do espermatozoide do ataque peroxidativo; além disso, na cauda do gameta masculino há um selenopeptídeo que faz com que, em uma deficiência de Se, produza-se uma fratura no meio da cauda do espermatozoide. -/- O esperma dos animais com deficiência de Se apresentam pobre motilidade com características de desenvolvimento anormal na cauda do esperma. Demonstrou-se que a deficiência de Se, não somente precipita o problema em reprodutores, mas que o esperma deformado, foi menos efetivo na subsequente fertilização do ovócito ovulado (HAWKES et al., 2001), ou seja, animais que possuem deficiência desse mineral podem ter esperma inapropriado para a destinação de inseminação artificial ou mesmo a monta natural, uma vez que a taxa de concepção estará bastante baixa. -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- BARRENHO, Gonçalo José Pinheiro.

This paper is aimed at understanding one central aspect of Bolzano's views on deductive knowledge: what it means for a proposition and for a term to be known a priori. I argue that, for Bolzano, a priori knowledge is knowledge by virtue of meaning and that Bolzano has substantial views about meaning and what it is to know the latter. In particular, Bolzano believes that meaning is determined by implicit definition, i.e. the fundamental propositions in a deductive system. I go (...) into some detail in presenting and discussing Bolzano's views on grounding, a priori knowledge and implicit definition. I explain why other aspects of Bolzano's theory and, in particular, his peculiar understanding of analyticity and the related notion of Ableitbarkeit might, as it has invariably in the past, mislead one to believe that Bolzano lacks a significant account oï a priori knowledge. Throughout the paper, I point out to the ways in which, in this respect, Bolzano's antagonistic relationship to Kant directly shaped his own views. (shrink)

Jusqu'à maintenant, il semble qu'on n'ait pas établi de lien entre le rejet par Bolzano de la notation quantificationnelle des propositions universelles de la logique traditionnelle et l'articulation inédite de sa notion de validité universelle. C'est ce que je veux faire ici. En particulier, dans la mesure où l'analyticité est un cas spécial de la validité universelle, j'ai l'intention de défendre l'idée qui veut que la notion bolzanienne d'analyticité cherche à résoudre des problèmes qui sont intrinsèquement liés à la théorie (...) traditionnelle de la quantification universelle tels qu'ils surviennent, notamment avec le traitement kantien de l'analyticité. It seems that the connection between Bolzano's rejection of the traditional quantificational notation for universal propositions and the articulation of his notion of universal validity has remained, until today, perfectly unnoticed. In this paper, I will show that there is such a connection. Particularly, since analyticity is a special case of universal validity, my intention is to show that the problems to which Bolzano's perfectly original account of analyticity seeks to find an answer are intrinsically related to the traditional conception of universal quantification as it arises in the context of Kant's treatment of analyticity.

In Reasons and Persons, Parfit (1984) posed a challenge: provide a satisfying normative account that solves the Non-Identity Problem, avoids the Repugnant and Absurd Conclusions, and solves the Mere-Addition Paradox. In response, some have suggested that we look toward person-affecting views of morality for a solution. But the person-affecting views that have been offered so far have been unable to satisfy Parfit's four requirements, and these views have been subject to a number of independent complaints. This paper describes a person-affecting (...) account which meets Parfit's challenge. The account satisfies Parfit's four requirements, and avoids many of the criticisms that have been raised against person-affecting views. (shrink)

This paper examines two puzzles of indeterminacy. The first puzzle concerns the hypothesis that there is a unified phenomenon of indeterminacy. How are we to reconcile this with the apparent diversity of reactions that indeterminacy prompts? The second puzzle focuses narrowly on borderline cases of vague predicates. How are we to account for the lack of theoretical consensus about what the proper reaction to borderline cases is? I suggest (building on work by Maudlin) that the characteristic feature of indeterminacy is (...) alethic normative silence, and use this to explain both plurality and lack of consensus. (shrink)

Moral fundamentalism is the habit of acting as though one has access to the exclusively right way to diagnose problems, along with the single approvable practical solution to any particular problem. This approach causes us to oversimplify situations, neglect broader context, take refuge in dogmatic absolutes, ignore possibilities for finding common ground, assume privileged access to the right way to proceed, and shut off honest inquiry. In this way, moral fundamentalism-exacerbated by social media silos-also makes the worst of native impulses (...) toward social bonding and antagonism. This makes it impossible to debate and achieve superordinate social goals, such as public health, justice, security, sustainability, peace, and democracy. Drawing from John Dewey's pluralistic and pragmatic approach to philosophical questions, Steven Fesmire develops an alternative to both the oversimplification of moral fundamentalism and the arbitrariness of relativism. His pragmatic pluralism is set up as a response to particular conditions and consequences, so it gains practical leverage with complex ethical, political, educational, and policy problems without flattening variability among values or presuming that abstract theories can determine what we ought to do. He argues that the reductive monistic premise that logically underlies moral fundamentalism is both unwarranted and constrictive, and there is little to be said in favor of the grand philosophical quest for a unifying principle that cannot be accommodated within a wider pluralistic approach. In a concrete and engaging style, Fesmire clarifies and illustrates the promises and challenges of democratic decision-making in societies struggling to grow beyond moral fundamentalism. (shrink)

At the heart of the Bayesianism is a rule, Conditionalization, which tells us how to update our beliefs. Typical formulations of this rule are underspecified. This paper considers how, exactly, this rule should be formulated. It focuses on three issues: when a subject’s evidence is received, whether the rule prescribes sequential or interval updates, and whether the rule is narrow or wide scope. After examining these issues, it argues that there are two distinct and equally viable versions of Conditionalization to (...) choose from. And which version we choose has interesting ramifications, bearing on issues such as whether Conditionalization can handle continuous evidence, and whether Jeffrey Conditionalization is really a generalization of Conditionalization.

Abstract. Richard Feldman’s Uniqueness Thesis holds that “a body of evidence justifies at most one proposition out of a competing set of proposi- tions”. The opposing position, permissivism, allows distinct rational agents to adopt differing attitudes towards a proposition given the same body of evidence. We assess various motivations that have been offered for Uniqueness, including: concerns about achieving consensus, a strong form of evidentialism, worries about epistemically arbitrary influences on belief, a focus on truth-conduciveness, and consequences for peer disagreement. (...) We argue that each of these motivations either misunderstands the commitments of permissivism or is question-begging. Better understanding permissivism makes it a much more plausible position.

This chapter takes the form of a discussion between the editors of this volume and Steven Lukes, one the most eminent critics of methodological individualism. The focus is on Lukes’ interpretation of methodological individualism in terms of linguistic exclusivism (i.e., naive reductionism), the multiple-realization problem, Boudon’s and Elster’s micro-foundationalist approach, ontological individualism, and the rationality of human action.

Supervaluationism is often described as the most popular semantic treatment of indeterminacy. There’s little consensus, however, about how to fill out the bare-bones idea to include a characterization of logical consequence. The paper explores one methodology for choosing between the logics: pick a logic thatnorms beliefas classical consequence is standardly thought to do. The main focus of the paper considers a variant of standard supervaluational, on which we can characterizedegrees of determinacy. It applies the methodology above to focus ondegree logic. (...) This is developed first in a basic, single-premise case; and then extended to the multipremise case, and to allowdegreesof consequence. The metatheoretic properties of degree logic are set out. On the positive side, the logic is supraclassical—all classical valid sequents are degree logic valid. Strikingly, metarules such as cut and conjunction introduction fail. (shrink)

The concept of similar systems arose in physics, and appears to have originated with Newton in the seventeenth century. This chapter provides a critical history of the concept of physically similar systems, the twentieth century concept into which it developed. The concept was used in the nineteenth century in various fields of engineering, theoretical physics and theoretical and experimental hydrodynamics. In 1914, it was articulated in terms of ideas developed in the eighteenth century and used in nineteenth century mathematics and (...) mechanics: equations, functions and dimensional analysis. The terminology physically similar systems was proposed for this new characterization of similar systems by the physicist Edgar Buckingham. Related work by Vaschy, Bertrand, and Riabouchinsky had appeared by then. The concept is very powerful in studying physical phenomena both theoretically and experimentally. As it is not currently part of the core curricula of STEM disciplines or philosophy of science, it is not as well known as it ought to be. (shrink)

Driven by technological innovations, newborn screening (NBS) panels have been expanded and the development of genomic NBS pilot programs is rapidly progressing. Decisions on disease selection for NBS are still based on the Wilson and Jungner (WJ) criteria published in 1968. Despite this uniform reference, interpretation of the WJ criteria and actual disease selection for NBS programs are highly variable. A systematic literature search [PubMED search “Wilson” AND “Jungner”; last search 16.07.22] was performed to evaluate the applicability of the WJ (...) criteria for current and future NBS programs and the need for adaptation. By at least two reviewers, 105 publications (systematic literature search, N = 77; manual search, N = 28) were screened for relevant content and, finally, 38 publications were evaluated. Limited by the study design of qualitative text analysis, no statistical evaluation was performed, but a structured collection of reported aspects of criticism and proposed improvements was instead collated. This revealed a set of general limitations of the WJ criteria, such as imprecise terminology, lack of measurability and objectivity, missing pediatric focus, and absent guidance on program management. Furthermore, it unraveled specific aspects of criticism on clinical, diagnostic, therapeutic, and economical aspects. A major obstacle was found to be the incompletely understood natural history and phenotypic diversity of rare diseases prior to NBS implementation, resulting in uncertainty about case definition, risk stratification, and indications for treatment. This gap could be closed through the systematic collection and evaluation of real-world evidence on the quality, safety, and (cost-)effectiveness of NBS, as well as the long-term benefits experienced by screened individuals. An integrated NBS public health program that is designed to continuously learn would fulfil these requirements, and a multi-dimensional framework for future NBS programs integrating medical, ethical, legal, and societal perspectives is overdue.

In an era where digital screens are as ubiquitous as the air we breathe, Toward an Anthropology of Screens by Mauro Carbone and Graziano Lingua offers a seminal exploration into screens’ crucial functions and profound impact on human culture. This scholarly work dissects the screen’s evolution, anthropological significance and philosophical implications, offering an enlightening narrative on our mediated reality.

This paper outlines Lewis’s favoured foundational account of linguistic representation, and outlines and briefly evaluates variations and modifications. Section 1 gives an opinionated exegesis of Lewis’ work on the foundations of reference—his interpretationism. I look at the way that the metaphysical distinction between natural and non-natural properties came to play a central role in his thinking about language. Lewis’s own deployment of this notion has implausible commitments, so in section 2 I consider variations and alternatives. Section 3 briefly considers a (...) buck-passing strategy involving fine-grained linguistic conventions. (shrink)

Governments around the world have faced the challenge of how to respond to the recent outbreak of a novel coronavirus disease. Some have reacted by greatly restricting the freedom of citizens, while others have opted for less drastic policies. In this paper, I draw a parallel with vaccination ethics to conceptualize two distinct approaches to COVID-19 that I call altruistic and lockdown. Given that the individual measures necessary to limit the spread of the virus can in principle be achieved voluntarily (...) as well as through enforcement, the question arises of how much freedom governments ought to give citizens to adopt the required measures. I argue that an altruistic approach is preferable on moral grounds: it preserves important citizen freedoms, avoids a number of potential injustices, and gives people a much-needed sense of meaning in precarious times.

This paper is a response to replies by Dan López de Sa and Mark Jago to my ‘Truthmaking, Entailment, and the Conjuction Thesis’. In that paper, my main aim was to argue against the Entailment Principle by arguing against the Conjunction Thesis, which is entailed by the Entailment Principle. In the course of so doing, although not essential for my project in that paper, I defended the Disjunction Thesis. López de Sa has objected both to my defence of the Disjunction (...) Thesis and my case against the Conjunction Thesis. I shall show that his objections are unfounded and based on serious misunderstandings of my position, what the relevant debate is, and some fundamental notions of Truthmaker Theory. Jago argues that accepting the Disjunction Thesis and rejecting the Conjunction Thesis is hard to maintain. But I show that Jago has not shown that accepting the Disjunction Thesis while rejecting the Conjunction Thesis is impossible or even hard to maintain. Jago believes that, to accept the Disjunction Thesis while rejecting the Conjunction Thesis, one needs to reject his axiom (T3), which says that all the truthmakers for <P&P> are truthmakers for <P>. I argue that there are reasons to reject such a principle, and the version of it that says that what makes <P&P> true makes <P> true. (shrink)

Investigation of neural and cognitive processes underlying individual variation in moral preferences is underway, with notable similarities emerging between moral- and risk-based decision-making. Here we specifically assessed moral distributive justice preferences and non-moral financial gambling preferences in the same individuals, and report an association between these seemingly disparate forms of decision-making. Moreover, we find this association between distributive justice and risky decision-making exists primarily when the latter is assessed with the Iowa Gambling Task. These findings are consistent with neuroimaging studies (...) of brain function during moral and risky decision-making. This research also constitutes the first replication of a novel experimental measure of distributive justice decision-making, for which individual variation in performance was found. Further examination of decision-making processes across different contexts may lead to an improved understanding of the factors affecting moral behaviour. (shrink)

In some sense, survival seems to be an intrinsic matter. Whether or not you survive some event seems to depend on what goes on with you yourself —what happens in the environment shouldn’t make a difference. Likewise, being a person at a time seems intrinsic. The principle that survival seems intrinsic is one factor which makes personal fission puzzles so awkward. Fission scenarios present cases where if survival is an intrinsic matter, it appears that an individual could survive twice over. (...) But it’s well known that standard notions of “intrinsicality” won’t do to articulate the sense in which survival is intrinsic, since ‘personhood’ appears to be a maximal property. We formulate a sense in which survival and personhood (and perhaps other maximal properties) may be almost intrinsic—a sense that would suffice, for example, to ground fission arguments. It turns out that this notion of almost-intrinsicality allows us to formulate a new version of the problem of the many. (shrink)

The Gettier problem has stymied epistemologists. But, whether or not this problem is resolvable, we still must face an important question: Why does the Gettier problem arise in the first place? So far, philosophers have seen it as either a problem peculiar to the concept of knowledge, or else an instance of a general problem about conceptual analysis. But I would like to steer a middle course. I argue that the Gettier problem arises because knowledge is a thick concept, and (...) a Gettier-like problem is just what we should expect from attempts at analyzing a thick concept. Section 2 is devoted to establishing the controversial claim that knowledge is thick, and, in Sect. 3, I show that there is a general problem for analyzing thick concepts of which the Gettier problem is a special instance. I do not take a stand on whether the Gettier problem, or its general counterpart, is resolvable. My primary aim is to bring these problems into better focus. (shrink)

Skeptical theism, broadly construed, is an attempt to leverage our limited cognitive powers, in some specified sense, against “evidential” and “explanatory” arguments from evil. Since there are different versions of these kinds of arguments, there are correspondingly different versions of skeptical theism. In this paper, I consider four challenges to three central versions of skeptical theism: (a) the problem of generalized skepticism, (b) the problem of moral skepticism, (c) the problem of unqualified modal skepticism, and (d) the challenge from Bayesian (...) epistemology.

Different sort of people are interested in personal identity. Philosophers frequently ask what it takes to remain oneself. Caregivers imagine their patients’ experience. But both philosophers and caregivers think from the armchair: they can only make assumptions about what it would be like to wake up with massive bodily changes. Patients with a locked-in syndrome (LIS) suffer a full body paralysis without cognitive impairment. They can tell us what it is like. Forty-four chronic LIS patients and 20 age-matched healthy medical (...) professionals answered a 15-items questionnaire targeting: (A) global evaluation of identity, (B) body representation and (C) experienced meaning in life. In patients, selfreported identity was correlated with B and C. Patients differed with controls in C. These results suggest that the paralyzed body remains a strong component of patients’ experienced identity, that patients can adjust to objectives changes perceived as meaningful and that caregivers fail in predicting patients’ experience.

Context: At present, we lack a common understanding of both the process of cognition in living organisms and the construction of knowledge in embodied, embedded cognizing agents in general, including future artifactual cognitive agents under development, such as cognitive robots and softbots. Purpose: This paper aims to show how the info-computational approach (IC) can reinforce constructivist ideas about the nature of cognition and knowledge and, conversely, how constructivist insights (such as that the process of cognition is the process of life) (...) can inspire new models of computing. Method: The info-computational constructive framework is presented for the modeling of cognitive processes in cognizing agents. Parallels are drawn with other constructivist approaches to cognition and knowledge generation. We describe how cognition as a process of life itself functions based on info-computation and how the process of knowledge generation proceeds through interactions with the environment and among agents. Results: Cognition and knowledge generation in a cognizing agent is understood as interaction with the world (potential information), which by processes of natural computation becomes actual information. That actual information after integration becomes knowledge for the agent. Heinz von Foerster is identified as a precursor of natural computing, in particular bio computing. Implications: IC provides a framework for unified study of cognition in living organisms (from the simplest ones, such as bacteria, to the most complex ones) as well as in artifactual cognitive systems. Constructivist content: It supports the constructivist view that knowledge is actively constructed by cognizing agents and shared in a process of social cognition. IC argues that this process can be modeled as info-computation. (shrink)

Healthcare is becoming increasingly automated with the development and deployment of care robots. There are many benefits to care robots but they also pose many challenging ethical issues. This paper takes care robots for the elderly as the subject of analysis, building on previous literature in the domain of the ethics and design of care robots. Using the value sensitive design approach to technology design, this paper extends its application to care robots by integrating the values of care, values that (...) are specific to AI, and higher-scale values such as the United Nations Sustainable Development Goals. The ethical issues specific to care robots for the elderly are discussed at length alongside examples of specific design requirements that work to ameliorate these ethical concerns. (shrink)
