Control measures, such as “lockdowns”, have been widely used to suppress the COVID-19 pandemic. Under some conditions, they prevent illness and save lives. But they also exact an economic toll. How should we balance the impact of such policies on individual lives and livelihoods (and other dimensions of concern) to determine which is best? A widely used method of policy evaluation, benefit–cost analysis (BCA), answers these questions by converting all the effects of a policy into monetary equivalents and then summing (...) them up. A different method, social welfare analysis, proceeds by determining the effects of a policy on individual wellbeing and then applying an aggregation formula to them to evaluate the overall effects of a policy. In this chapter, we survey these methods and argue that social welfare analysis has important advantages. One crucial advantage is that it enables ethical considerations relating to the impact of policies on individual wellbeing and its distribution to be incorporated into policy assessments in a transparent way. We illustrate this with a simple numerical model for evaluating pandemic policies that vary in terms of the stringency of the controls that they impose on individual behaviour, showing how the evaluation depends on the ethical significance accorded to their impact on the wellbeing of different age and income groups.

The COVID-19 crisis has forced a difficult trade-off between limiting the health impacts of the virus and maintaining economic activity. Welfare economics offers tools to conceptualize this trade-off so that policy-makers and the public can see clearly what is at stake. We review four such tools: the Value of Statistical Life (VSL); the Value of Statistical Life Years (VSLYs); Quality-Adjusted Life-Years (QALYs); and social welfare analysis, and argue that the latter are superior. We also discuss how to choose policies that (...) differentially affect people’s wellbeing. We argue in favor of evaluating policies using a Social Welfare Function (SWF), which evaluates the possible distributions of wellbeing across individuals that may result from a policy. Such a function, we argue, should regard increases in the wellbeing of the less well-off as especially valuable. We then use a model to illustrate how such a framework can help evaluate two broad policy types in response to the pandemic: eradication of the virus, and more lenient control of the spread. Our model reveals how such evaluations depend on many empirical facts but also on key value judgments about the relative importance of health and on the extent of special concern for the worse off. The purpose of this brief is not to make precise recommendations, as conditions vary widely across countries and over time, but to provide a methodology. (shrink)

La complejidad del mundo actual demanda de nuevas formas de pensar, diferentes a las convencionales. La educación exige cambios acelerados en la formación de los seres humanos. Cambios impredecibles que toman por sorpresa, quizá se está frente a una transformación en contextos geográficos, comunicación, convivencia con los ‘otros’; todo ello afectado por las transformaciones constantes. A la par de estas transformaciones, las grandes problemáticas sociales, ambientales, políticas, económicas continúan creciendo, no se logra alcanzar una sostenibilidad en el estilo de vida (...) de las sociedades. Es cierto que estamos en un mundo globalizado gracias a la Internet y a las Tecnologías de la Información y la Comunicación (TIC), por consecuente la información está al alcance de la mayoría de los seres humanos. Si el planeta está al frente de una globalización tecnológica, la educación también debe globalizarse, sin perder la identidad local. De ahí nace el desafío de reinventar los procesos de formación, direccionarlos hacia la transformación social, y al desarrollo de competencias profesionales básicas como el ‘aprender a vivir juntos’ bajo los cánones éticos que como civilización históricamente se practica.

Doctoral graduates in philosophy are an excellent source of information about the discipline: they are at the cutting edge of research trends, have an inside view of researchfocused departments, and their employment prospects provide early insights on the future health of the discipline. We report on the results of a survey sent to recent PhD graduates and current students, as well as data gathering efforts by Academic Placement Data and Analysis that have taken place over the past ten years. In (...) this report we especially focus on demographic representation, program ratings, academic job placement, and non-academic careers. (shrink)

Background: how mind functions is subject to continuing scientific discussion. A simplistic approach says that, since no convincing way has been found to model subjective experience, mind cannot exist. A second holds that, since mind cannot be described by classical physics, it must be described by quantum physics. Another perspective concerns mind's hypothesized ability to interact with the world of quanta: it should be responsible for reduction of quantum wave packets; physics producing 'Objective Reduction' is postulated to form the basis (...) for mind-matter interactions. This presentation describes results derived from a new approach to these problems. It is based on well-established biology involving physics not previously applied to the fields of mind, or consciousness studies, that of critical feedback instability. -/- Methods: 'self-organized criticality' in complexity biology places system loci of control at critical instabilities, physical properties of which, including information properties, are presented. Their elucidation shows that they can model hitherto unexplained properties of experience. -/- Results: All results depend on physical properties of critical instabilities. First, at least one feed-back or feed-forward loop must have feedback gain, g = 1: information flows round the loop impress perfect images of system states back on themselves: they represent processes of perfect self-observation. This annihilates system quanta: system excitations are instability fluctuations, which cannot be quantized. Major results follow: -/- 1. Information vectors representing criticality states must include at least one attached information loop denoting self-observation. -/- 2. Such loop structures are attributed a function, 'registering the state's own existence', explaining -/- a. Subjective 'awareness of one's own presence' -/- b. How content-free states of awareness can be remembered (Jon Shear) -/- c. Subjective experience of time duration (Immanuel Kant) -/- d. The 'witness' property of experience – often mentioned by athletes 'in the zone' -/- e. The natural association between consciousness and intelligence -/- This novel, physically and biologically sound approach seems to satisfactorily model subjectivity. -/- Further significant results follow: -/- 1. Registration of external information in excited states of systems at criticality reduces external wave-packets: the new model exhibits 'Objective Reduction' of wave packets. -/- 2. High internal coherence (postulated by Domash & Penrose) leading to a. Non-separable information vector bundles. b. Non-reductive states (Chalmers's criterion for experience). -/- 3. Information that is: a. encoded in coherence negentropy; b. non-digitizable, and therefore c. computationally without digital equivalent (posited by Penrose). -/- Discussion and Conclusions: instability physics implies anharmonic motion, preventing excitation quantization, and totally different from the quantum physics of simple harmonic motion at stability. Instability excitations are different from anything hitherto conceived in information science. They can model aspects of mind never previously treated, including genuine subjectivity, objective reduction of wave-packets, and inter alia all properties given above. (shrink)

Abstract: This working paper focuses on the question whether there is a therapeutic imperative that, in specific situations, would oblige us to perform genome editing at the germline level in the context of assisted reproduction. The answer to this central question is discussed primarily with reference to specific scenarios where preimplantation genetic diagnosis (PGD) does not represent an acceptable alternative to germline genome editing based on either medical, or ethical, or – from the perspective of the potential parents – moral (...) or religious grounds. This article deals with four different types of case constellations that result from these possible reasons against PGD as well as from the necessity or dispensability of a subsequent “control PGD.” These cases are discussed based on hypotheses concerning contextual factors and theoretical assumptions. In conclusion, we point out that if our assumptions are correct, there is probably no therapeutic imperative for genome editing at the germline level. We draw this rationale from the fact that germline interventions are likely not person-affecting. However, we caution the reader that our result is preliminary and needs to be more carefully examined in future work in light of the bioethical debate and potential objections. -/- // Abstract: Im Zentrum dieses Working Papers steht die Frage, ob es einen therapeutischen Imperativ geben kann, der uns, in bestimmten Situationen, verpflichten würde, eine Genomeditierung (genome editing) auf Keimbahnebene im Rahmen der assistierten Befruchtung vorzunehmen. Die Antwort auf diese zentrale Frage wird insbesondere mit Bezug auf Fälle diskutiert, in denen das Verfahren der Präimplantationsdiagnostik (PID) keine aus entweder medizinischen oder ethischen oder – aus Sicht der potentiellen Eltern – moralischen bzw. religiösen Gründen akzeptable Alternative zu einem Keimbahneingriff darstellt. Die möglichen Gründe gegen die PID sowie die Erforderlichkeit oder Verzichtbarkeit einer nachfolgenden «Kontroll-PID» ergeben vier verschiedene Fallkonstellationen, denen sich der Beitrag zuwendet. Auf Grundlage von Hypothesen zu kontextuellen Faktoren und theoretischen Annahmen diskutieren wir diese Fälle. Im Ergebnis verweisen wir darauf, dass es, wenn unsere Annahmen zutreffen, vermutlich keinen therapeutischen Imperativ zum genome editing auf Keimbahnebene gibt. Dies begründet sich daraus, dass der Keimbahneingriff vermutlich nicht als personenbezogen (person-affecting) zu bezeichnen ist. Wir weisen jedoch darauf hin, dass unser Ergebnis vorläufig ist und unter Berücksichtigung der bioethischen Debatte und möglicher Einwände genauer geprüft werden muss. -/- // Résumé: Ce Working Paper se concentre sur la question de l’existence d’un impératif thérapeutique qui, dans des situations spécifiques, nous obligerait à réaliser une édition du génome au niveau de la lignée germinale dans le cadre de la procréation assistée. Afin de répondre à cette question centrale nous développons quatre scénarios spécifiques dans lesquels le diagnostic préimplantatoire (DPI) ne représente pas une alternative acceptable à l’édition du génome germinal pour des raisons médicales, éthiques ou – du point de vue des futurs parents – morales ou religieuses. Cet article traite de quatre constellations différentes de cas résultant des raisons mises en avant pour s'opposer au DPI ainsi que de la nécessité ou de l’inutilité d’un ultérieur « DPI de contrôle » Ces cas sont discutés sur la base d’hypothèses portant sur les facteurs contextuels et sur les présupposés théoriques. En conclusion, nous soulignons que si nos hypothèses sont correctes, il n’y a probablement aucun impératif thérapeutique justifiant l’édition du génome au niveau de la lignée germinale. Nous arrivons à cette conclusion parce qu’une intervention au niveau de la lignée germinale n’est probablement pas susceptible d’affecter la personne. Cependant, nous mettons en garde le lecteur sur le fait que notre conclusion est préliminaire et qu’elle doit être examinée avec soin dans des futurs travaux instruits par le débat bioéthique et par les éventuelles objections.

El presente trabajo de Alex Ibarra Peña recoge los resultados de una investigación cuyo tema es la constitución de un campo de estudios ligado a la filosofía analítica en Chile. El autor se propone una tarea informativa y crítica en la que cifra la novedad de su propuesta. En otros términos, la suya es una labor de rescate, de algunos filósofos y corrientes de pensamiento relegados en las narraciones hegemónicas de la institucionalización de la filosofía en Chile y una (...) tarea que busca corregir el papel asignado a Chile en las visiones panorámicas de mayor circulación sobre la emergencia de la filosofía analítica en nuestro continente. En el cruce de estos dos vectores radica la novedad de la empresa de Ibarra Peña: proponer una visión más ajustada de la recepción de los filósofos analíticos en Chile. En nuestra reseña comentamos los núcleos centrales del trabajo y proponemos algunas hiótesis sobre los conflictos internos al campo cultural que subyacen a las opciones realizadas por el autor. Para finalizar indicamos lo que nos parece ser una falencia del trabajo: un estudio de la constitución de la filosofía analística como campo de estudios no debería dejar de tener en cuenta que el énfasis en la delimitación de la cientificidad por la filosofía analítica tenía en los años 60 y 70 adversarios concretos en el marxismo y el psicoanálisis.

Tout le film est toujours une microphysique du pouvoir, en potence, d’être étudier. Aujourd’hui l'augmentation des productions d'horreur et son public ont fait le film d'horreur une «contreculture» dominante, mais toujours sous l'effet négatif du pouvoir et du savoir qui disqualifient les discours, matérialisée dans ces films, ce qui les rend illégitime et exiler en soi espace filmique, transformée en un lieu adapté pour interdite et marquée par certaines pratiques discursives avec certains dispositifs d'exclusion. Paradoxalement, les types marginaux qui apparaissent (...) dans l'ordre de ces productions occupent les positions de sujets à exercer le pouvoir dans l'horreur et dans le même temps le renforcement de leur marginalité et de son objectivation. Ces aspects et les spécificités qui caractérisent les productions d'une part, nous ont amenés à identifier les pratiques de l'objectivation qui transforment corps dans les sujets dans l'horreur; d'autre part, de démontrer que ces films constituent une nouvelle technologie de contrôle social des corps, mais l'objectif principal de cette étude est d'analyser les relations de pouvoir à travers l'antagonisme des stratégies dans ce discours, qui est, pour savoir ce que cela signifie d'avoir un corps libre, nous examinons ce qui se passe sur le corps subjugué dans les films d'horreur, prenant l'archeogenealogie de Foucault comme base théorique. Cette questionhypothèse aurait un autre groupe: d'où pourrait faire une telle histoire? Nous supposons que dans les moments de crise, les films d'horreur ont beaucoup à prouver, donc nous avons opté pour un très similaire à celui qui Foucault a été invité par les experts de la revue Cahiers du cinéma pour discuter des conditions pour les productions cinématographiques comme Le Chagrin et la Pitié (1969), Portier de nuit (1974) et Lacombe Lucien (1974), quand on a regardé le déclin du gaullisme et l’ascention de Valéry Giscard d'Estaing , le vainqueur de la présidentielle de 1974, avec le soutien de l'ancien droit Tardieu et petainistes, anciens alliés de l'occupation du Führer Hitler de la France, entre 1940 à 1943. Maintenant, les conditions de production sont ceux qui marquent la fin des gouvernements socialistes de Mitterrand et Chirac, et le retour au pouvoir de la droite, à l'ascension politique de Nicolas Sarkozy. Au milieu de la crise économique de l'Union Européenne, flotte dans l'air la peur terrifiante de risque que l'arrivée de l'extrême droite au pouvoir. La présence croissante d'immigrants est aussi dans l'ordre d'une nouvelle crise de l'identité française. Ce sont les conditions de production de À l'intérieur, Frontière (s),Martyrs, Ils, La Meute, Captifs et Derrière les murs et, des films qui font partie de notre corpus. À la methodologie, nous développons les trois concepts opérationnels: le dispositif filmique de la mémoire, de la vérité et de l'objectivité pour traiter la mémoire populaire, recodé dans ces films et soi-disant perçu par nous comme l'un des principaux modes de contrôle des corps d’horreur; la notion d’intericonicité est encore utilisée pour indiquer des images qui renvoient à d'autres, mais tout en réalisant que chaque image a dans sa juxtaposition afin de utopies des hétérotopies. Donc, nous avons décidé de donner une nouvelle forme à cette notion, y compris l'utopique juxtaposés à des espaces hétérotopiques, sous l'influence de la discussion faite par Foucault dans le Corps utopique et Les hétérotopies. Keyword:Mémoire. Corps. Pouvoir. Discours politique. Film français d’horreur. (shrink)

This is a letter from an amateur philosopher to Alex Byrne expressing perplexity on reading Byrne's chapter in The Oxford Handbook of the Philosophy of Mind, "Sensory Qualities, Sensible Qualities, Sensational Qualities" (2009). A version of the theory of indirect perception is described using several analogies and one autobiographical episode. It is described as a realization that occurred historically and may occur to individuals, supplanting default naive realism. Byrne's readings of various philosophers' accounts of sensory qualities are then contrasted (...) with an interpretation consistent with the adduced theory of indirect perception. The difficulty of imagining the view from the opposite side of the direct/indirect perception divide is remarked upon. (shrink)

A review of Francoise Laruelle's General Theory of Victims, which places Laruelle's theory in the context of post-colonial theories of the subaltern subject after Gayatri Spivak and Edward Said. The review questions whether Laruelle's General Theory of Victims really allows the so-called victims to speak for themselves, or simply represents another attempt by Western (French?) intellectuals to speak to/through the victims, for their own political and theoretical purposes.

Bence Nanay has argued that we must abandon the etiological theory of teleological function because this theory explains functions and functional categories in a circular manner. Paul Griffiths argued earlier that we should retain the etiological theory and instead prevent the circularity by making etiologies independent of functional categories. Karen Neander and Alex Rosenberg reply to Nanay similarly, and argue that we should analyze functions in terms of natural selection acting not on functional categories, but merely on lineages. Nanay (...) replies that these lineages cannot be individuated except by reference to functional categories. Worryingly, Neander and Rosenberg themselves have previously argued persuasively that homology often depends on function. This article addresses their arguments and shows how to escape them: Regardless whether the arguments are right about long-term homological categories, they do not apply to generation-to-generation homology. The latter, moreover, is sufficient for individuating the lineages needed to explain teleological functions. (shrink)

RELAÇÃO E EFEITOS BIOQUÍMICO-NUTRICIONAIS SOBRE A METRITE EM VACAS -/- Emanuel Isaque Cordeiro da Silva Departamento de Agropecuária – IFPE Campus Belo Jardim [email protected] ou [email protected] WhatsApp: (82)98143-8399 -/- •__3. METRITE -/- O transtorno caracterizado pela inflamação do útero, devido a causas sépticas ou assépticas que atuam sobre ele, denomina-se genericamente como metrite. As metrites são afecções de grande importância, tanto pela frequência como pela gravidade. As metrites podem ser divididas segundo seu caráter anatômico, como mucosa (catarral), purulenta, hemorrágica, crupal, (...) pútrida e flegmonosa e segundo seu curso, em agudas e crônicas (FRAZER, 2005; GORDON, 1996). Estão associadas às doenças do puerpério. Quando a inflamação é limitada à mucosa é chamada de endometrite; e se ademais interessa a camada muscular denomina-se metrite ou miometrite; se afeta o revestimento peritoneal, perimetrite ou metroperitonite; e se a inflamação se estende ao paramétrio, ou seja, ao tecido conjuntivo pélvico e ligamentos, chama-se parametrite (FÖLDI, et al. 2006). A metrite ocorre em consequência de diversos acidentes que resultam de partos distócicos, após retenção fetal ou secundinas seguidas de putrefação, por arrancamento brutal dos cotilédones; por injeções uterinas irritantes; após o prolapso uterino; tudo o que favorece o desenvolvimento microbiano. Em fêmeas que se inseminam artificialmente sob condições sépticas ou de pobre destreza se produz endometrite seguida com infecundidade passageira, isto se produz como consequência das erosões produzidas pela pistola de inseminação, desassossego geral no procedimento ou por levar o sêmen a maior temperatura que a devida e em lugar inadequado. Algumas situações de origem nutricional se associam em maior ou menor grau com a incidência de metrite, em especial processos de retenção de placenta ou involução uterina de origem nutricional podem levar, de forma indireta, a incidência de metrite. 3.1 Relação energia e proteína Uma das situações de origem nutricional associada à metrite é o excesso de proteína crua na dieta. As vacas necessitam de um adequado fornecimento de proteína. No afã de suprir as necessidades nutricionais e evitar as limitações de aminoácidos, cai-se no erro de fornecer excessos de proteína, trazendo como consequência uma diminuição da eficiência reprodutiva, devido à relação dos altos níveis de proteína na dieta com a falha reprodutiva específica. Um excesso de proteína resulta num aumento da produção de amoníaco e, como consequência, numa maior síntese de ureia pelo fígado (BACH, 2000). Consequentemente, existe um aumento do nível de ureia no sangue, no útero e no muco vaginal. A nível uterino, a ureia parece ter um efeito sobre a função hormonal e depressora da proteção imunitária. O mecanismo específico baseia-se na toxicidade direta da ureia, na perda do balanço energético e na concentração de diaminas de ácido carbônico que favorecem a ampla difusão da ureia em todo o endométrio. O fornecimento de fontes alternativas de nitrogênio na alimentação dos animais vêm ganhando espaço no debate entre os especialista e a ureia é uma dessas fontes. Ela é conhecida como uma fonte de nitrogênio não-proteico (NNP), porém não se destaca tanto pelos inúmeros fatores negativos como a baixa aceitabilidade dos animais ou aos índices de intoxicação pela mesma. O rúmen necessita de um teor de 1% de nitrogênio para manter os mecanismos fisiológicos e a população microbiana, sendo assim, o produtor deve estar atento ao fornecimento desse mineral para seus animais. Especialistas apontam a fórmula de 30 g de ureia por dia para animais de 100 kg, e que essa quantidade nunca pode exceder os 200 g por animal por dia. Esses dados só podem ser postos em prática se as forrageiras existentes na propriedade não conseguirem suprir a exigência de 1% de nitrogênio no animal. Uma fonte vegetal de ótima qualidade e abundante em meios nutricionais e fonte extra de renda é a cana-de-açúcar. Ao nível hormonal a presença de ureia impede a manutenção do gradiente de pH (induzido pela progesterona) que existe entre as células apicais e basais da parede uterina (MARÍN & CÁRDENAS, 1999). Assim, a progesterona não consegue manter o gradiente de pH e aumenta a secreção de PGF2α, que afeta negativamente tanto a sobrevivência como o desenvolvimento embrionário. A nível imunológico, ocorre um efeito negativo devido à elevada concentração de amônio e ureia no sangue, o que diminui a atividade dos linfócitos e impede a defesa celular contra os agentes nocivos provocadores da metrite infecciosa, favorecendo o desenvolvimento microbiano. Para determinar a quantidade e a qualidade da nutrição proteica do animal são utilizados indicadores como a concentração de ureia no sangue e no leite. As proteínas, em geral, possuem inúmeras funções, dentre elas componentes estruturais, funções enzimáticas, funções hormonais, recepção de estímulos hormonais e armazenamento de informações genéticas. Na nutrição animal, as proteínas são divididas entre bruta (PB) e metabolizável (PM), ainda outras, mas o enfoque são essas. Os animais necessitam de níveis distintos de proteínas em suas respectivas fases de vida. Para elucidar melhor, tomemos como exemplo uma vaca nelore de 420 kg no final da gestação necessita, em média, de 389 g/dia de proteína metabolizável e, em média de 581 g/dia de proteína bruta. Os alimentos de origem vegetal (forrageiras) fornecem muito bem e eficazmente teores aceitáveis de proteínas, porém como o elemento mais presente é a fibra, faz-se necessário a suplementação nos animais, e um meio de suprir as necessidades dos mesmo, é optando por farelos de soja que possuem mais de 60% de proteína em sua composição, ou outras fontes alternativas como as farinhas de origem animal como a de sangue, por exemplo. A deficiência de fibra crua desencadeia principalmente uma deficiência de energia no ruminante; pois a partir da fibra formam-se os ácidos graxos voláteis (AGV) que constituem até 60% das fontes energéticas para estes animais. Devido à síntese reduzida de AGV, é muito baixa a concentração destes, são absorvidos pela corrente sanguínea e o animal entra em estado de déficit de precursores glicogênios. Como o consumo de alimento no pós-parto está reduzido, e não há a suficiente disposição de energia (deficiência de AGV principalmente ácido acético, devido a deficiência em fibra crua), o organismo realiza uma mobilização de ácidos graxos para a compensação energética. Os ácidos graxos são levados até acetil-CoA, este é convertido pelo fígado em corpos cetônicos que são utilizados em baixa concentração por alguns tecidos periféricos (cérebro) como fonte de energia, pois os excessos de corpos cetônicos produzem toxicidade. Os excessos de acetil-CoA no fígado podem sofrer condensação e converterem-se em β-hidroxi-β-metil-glutaril-CoA que serve como fonte de mevalonato (precursor do colesterol formado em excesso). Os excessos provocam fígado graxo que gera danos hepáticos, isso deprime a síntese de ácidos graxos para a formação do colesterol que se encontra diretamente implicado na síntese de estrogênios. Após o parto uma deficiência de estrogênio provoca de forma subsequente atonia uterina, retenção de placenta, endometrite puerperal e finalmente metrite. 3.2 Vitaminas Outra causa nutricional que incide na manifestação de metrite, é a vitamina A, que faz parte do grupo de vitaminas lipossolúveis e tem relevância especial na função reprodutiva. Esta exerce sua ação sobre a integridade estrutural e funcional das células epiteliais do organismo animal, atua sobre o crescimento, a reprodução e o desenvolvimento embrionário; mas seu papel principal é atuar como protetora dos epitélios, incluindo o endométrio. Além disso, tem um efeito estabilizador sobre várias membranas celulares e atua regulando a permeabilidade da membrana. A vitamina A, atua como estimuladora dos epitélios da mucosa tubária, uterina e vaginal, aumentando sua resistência contra os agentes infecciosos que produzem problemas que finalizam em metrite, também é necessária para as alterações histológicas que ocorrem na mucosa durante as diferentes fases do ciclo estral. Uma deficiência de vitamina A, pode causar morte embrionária, aborto, bezerros fracos ao nascimento e de forma subsequente uma retenção de placenta, (BACH, 2000) devido a não regulação da filtração de líquidos e gases através das membranas fetais; também dificulta a fecundação, devido à geração de uma atresia ovariana e à degeneração do epitélio germinal. Além disso, são produzidos edemas que ocasionam bezerros mortos ou prematuros (natimortos), o que provoca uma posterior retenção de placenta. Estas retenções provocam metaplasia queratinizam-te, dos epitélios da mucosa uterina-vaginal, o que provoca o aparecimento de metrite. Também, uma deficiência de outras vitaminas provocam o aparecimento de pequenas hemorragias, inchaço vulvar e degeneração epitelial das mucosas, em geral, isto provoca uma endometrite que posteriormente torna-se em metrite devido ao que se afeta a submucosa e a camada muscular do útero. Em relação ao pós-parto precoce, a capacidade de consumo de alimentos (forragem) é limitada, o que conduz, principalmente, a uma deficiência de fibras cruas na ruminação do animal, que conduzirá, em algumas circunstâncias, à predisposição para o desenvolvimento de metrite. Atentos a essas intempéries, o produtor deve estar atento aos requerimento exigidos pelos animais de vitaminas para que possam manter seu funcionamento normal e longe de quaisquer problema ou agente infeccioso ou patógeno. Para tanto, os níveis de vitaminas por categoria animal, deve prezar pelas quantidades conforme demonstrado nas tabelas abaixo: Tabela 1: Exigências de vitaminas por categoria animal em bovinos de corte -/- Categoria Vitamina A (UI/dia) Vitamina E (mg/dia) Vitamina D (UI/dia) Niacina (g/dia) Vacas lactantes 80.000 – 120.000 100 – 1.000 15.000 – 50.000 1 - 2 Vacas secas 75.000 – 125.000 500 – 900 10.000 – 20.000 0 – 1 Fonte: BERCHIELLI et al., 2006. Tabela 2: Exigências de vitaminas em vacas gestantes de corte -/- Vitamina UI/kg de MS A 2.800 D 275 Fonte: BERCHIELLI et al., 2006. Para que se consiga suprir todas essas quantidades requeridas dos animais, em especial, das vacas gestantes para que não venha a ocorrer a incidência de metrite ou outro transtorno reprodutivo, o criador poderá optar pela injeção direta de complexos vitamínicos e minerais mediante os inúmeros fármacos da indústria farmacêutica animal, ou poderá suprir essas necessidades fisiológicas mediante o fornecimento de rações com teores adequados de vitaminas, ou ainda por intermédio de alimentos volumosos que além das vitaminas necessárias fornecem também as fibras. As forrageiras, leguminosas e gramíneas fornecem minerais, fibras e vitaminas; dentre elas as espécies tifton (capim) apresenta cerca de 34,8% de vitamina A, o capim-tanzânia apresenta 24% e a alfafa 23,4%. Por fim, métodos para fornecimento de fibras, vitaminas e/ou minerais não faltam. Apoio -/- Realização •_ _referências bibliográficas -/- BACH, Alex; ESPAÑA, Purina.

Many believe that we ought to save a large number from being permanently bedridden rather than save one from death. Many also believe that we ought to save one from death rather than a multitude from a very minor harm, no matter how large this multitude. I argue that a principle I call “Aggregate Relevant Claims” satisfactorily explains these judgments. I offer a rationale for this principle and defend it against objections.

The paper points out that the modern formulation of Bohm’s quantum theory known as Bohmian mechanics is committed only to particles’ positions and a law of motion. We explain how this view can avoid the open questions that the traditional view faces according to which Bohm’s theory is committed to a wave-function that is a physical entity over and above the particles, although it is defined on configuration space instead of three-dimensional space. We then enquire into the status of the (...) law of motion, elaborating on how the main philosophical options to ground a law of motion, namely Humeanism and dispositionalism, can be applied to Bohmian mechanics. In conclusion, we sketch out how these options apply to primitive ontology approaches to quantum mechanics in general. (shrink)

Causation is one of philosophy's most venerable and thoroughly-analyzed concepts. However, the study of how ordinary people make causal judgments is a much more recent addition to the philosophical arsenal. One of the most prominent views of causal explanation, especially in the realm of harmful or potentially harmful behavior, is that unusual or counternormative events are accorded privileged status in ordinary causal explanations. This is a fundamental assumption in psychological theories of counterfactual reasoning, and has been transported to philosophy by (...) Hitchcock and Knobe (2009). A different view--the basis of the culpable control model of blame (CCM)--is that primary causal status is accorded to behaviors that arouse negative evaluative reactions, including behaviors that stem from nefarious motives, negligence or recklessness, a faulty character, or behaviors that lead to harmful or potentially harmful consequences. This paper describes four empirical studies that show consistent support for the CCM. (shrink)

Some scientific categories seem to correspond to genuine features of the world and are indispensable for successful science in some domain; in short, they are natural kinds. This book gives a general account of what it is to be a natural kind and puts the account to work illuminating numerous specific examples.

Research suggests that interventions involving extensive training or counterconditioning can reduce implicit prejudice and stereotyping, and even susceptibility to stereotype threat. This research is widely cited as providing an “existence proof” that certain entrenched social attitudes are capable of change, but is summarily dismissed—by philosophers, psychologists, and activists alike—as lacking direct, practical import for the broader struggle against prejudice, discrimination, and inequality. Criticisms of these “debiasing” procedures fall into three categories: concerns about empirical efficacy, about practical feasibility, and about the (...) failure to appreciate the underlying structural-institutional nature of discrimination. I reply to these criticisms of debiasing, and argue that a comprehensive strategy for combating prejudice and discrimination should include a central role for training our biases away. (shrink)

Many philosophers and psychologists have attempted to elucidate the nature of mental representation by appealing to notions like isomorphism or abstract structural resemblance. The ‘structural representations’ that these theorists champion are said to count as representations by virtue of functioning as internal models of distal systems. In his 2007 book, Representation Reconsidered, William Ramsey endorses the structural conception of mental representation, but uses it to develop a novel argument against representationalism, the widespread view that cognition essentially involves the manipulation of (...) mental representations. Ramsey argues that although theories within the ‘classical’ tradition of cognitive science once posited structural representations, these theories are being superseded by newer theories, within the tradition of connectionism and cognitive neuroscience, which rarely if ever appeal to structural representations. Instead, these theories seem to be explaining cognition by invoking so-called ‘receptor representations’, which, Ramsey claims, aren’t genuine representations at all—despite being called representations, these mechanisms function more as triggers or causal relays than as genuine stand-ins for distal systems. I argue that when the notions of structural and receptor representation are properly explicated, there turns out to be no distinction between them. There only appears to be a distinction between receptor and structural representations because the latter are tacitly conflated with the ‘mental models’ ostensibly involved in offline cognitive processes such as episodic memory and mental imagery. While structural representations might count as genuine representations, they aren’t distinctively mental representations, for they can be found in all sorts of non-intentional systems such as plants. Thus to explain the kinds of offline cognitive capacities that have motivated talk of mental models, we must develop richer conceptions of mental representation than those provided by the notions of structural and receptor representation.

The no-miracles argument and the pessimistic induction are arguably the main considerations for and against scientific realism. Recently these arguments have been accused of embodying a familiar, seductive fallacy. In each case, we are tricked by a base rate fallacy, one much-discussed in the psychological literature. In this paper we consider this accusation and use it as an explanation for why the two most prominent `wholesale' arguments in the literature seem irresolvable. Framed probabilistically, we can see very clearly why realists (...) and anti-realists have been talking past one another. We then formulate a dilemma for advocates of either argument, answer potential objections to our criticism, discuss what remains (if anything) of these two major arguments, and then speculate about a future philosophy of science freed from these two arguments. In so doing, we connect the point about base rates to the wholesale/retail distinction; we believe it hints at an answer of how to distinguish profitable from unprofitable realism debates. In short, we offer a probabilistic analysis of the feeling of ennui afflicting contemporary philosophy of science. (shrink)

This chapter explores the idea that causal inference is warranted if and only if the mechanism underlying the inferred causal association is identified. This mechanistic stance is discernible in the epidemiological literature, and in the strategies adopted by epidemiologists seeking to establish causal hypotheses. But the exact opposite methodology is also discernible, the black box stance, which asserts that epidemiologists can and should make causal inferences on the basis of their evidence, without worrying about the mechanisms that might underlie their (...) hypotheses. I argue that the mechanistic stance is indeed a bad methodology for causal inference. However, I detach and defend a mechanistic interpretation of causal generalisations in epidemiology as existence claims about underlying mechanisms. (shrink)

If I were asked to put forward an ethical principle which I considered to be especially certain, it would be that no one can be responsible, in the properly ethical sense, for the conduct of another. Responsibility belongs essentially to the individual. The implications of this principle are much more far-reaching than is evident at first, and reflection upon them may lead many to withdraw the assent which they might otherwise be very ready to accord to this view of responsibility. (...) But if the difficulties do appear to be insurmountable, and that, very certainly, does not seem to me to be the case, then the proper procedure will be, not to revert to the barbarous notion of collective or group responsibility, but to give up altogether the view that we are accountable in any distinctively moral sense.

Although philosophers of art and aesthetics regularly appeal to a notion of ‘pictorial content’, there is little agreement over its nature. The present paper argues that pictures have propositional contents. This conclusion is reached by considering a style of argument having to do with the phenomenon of negation intended to show that pictures must have some kind of non-propositional content. I first offer reasons for thinking that arguments of that type fail. Second, I show that when properly understood, such arguments (...) can in fact be turned on their heads and shown to support the propositionalist position. (shrink)

According to orthodoxy, perceptual beliefs are caused by perceptual experiences. The paper argues that this view makes it impossible to explain how experiences can be epistemically significant. A rival account, on which experiences in the “good case” are ways of knowing, is set out and defended.

This paper evaluates the Natural-Kinds Argument for cognitive extension, which purports to show that the kinds presupposed by our best cognitive science have instances external to human organism. Various interpretations of the argument are articulated and evaluated, using the overarching categories of memory and cognition as test cases. Particular emphasis is placed on criteria for the scientific legitimacy of generic kinds, that is, kinds characterized in very broad terms rather than in terms of their fine-grained causal roles. Given the current (...) state of cognitive science, I conclude that we have no reason to think memory or cognition are generic natural kinds that can ground an argument for cognitive extension.

Response-dependence theories have historically been very popular in aesthetics, and aesthetic response-dependence has motivated response-dependence in ethics. This chapter closely examines the prospects for such theories. It breaks this category down into dispositional and fittingness strands of response-dependence, corresponding to descriptive and normative ideal observer theories. It argues that the latter have advantages over the former but are not themselves without issue. Special attention is paid to the relationship between hedonism and response-dependence. The chapter also introduces two aesthetic properties that (...) lead to wrong kinds of reasons problems for aesthetic response-dependence: insightfulness and the capacity to change one’s perspective. These properties do not have obvious parallels in the ethical domain, and so present an obstacle for response-dependence even in aesthetics. The chapter ends by examining replies on behalf of the response-dependence theorist, ultimately suggesting that a restricted form of response-dependence is the most promising way forward for fans of such theories.

This chapter is centered around an apparent tension that research on implicit bias raises between virtue and social knowledge. Research suggests that simply knowing what the prevalent stereotypes are leads individuals to act in prejudiced ways—biasing decisions about whom to trust and whom to ignore, whom to promote and whom to imprison—even if they reflectively reject those stereotypes. Because efforts to combat discrimination obviously depend on knowledge of stereotypes, a question arises about what to do next. This chapter argues that (...) the obstacle to virtue is not knowledge of stereotypes as such, but the “accessibility” of such knowledge to the agent who has it. “Accessibility” refers to how easily knowledge comes to mind. Social agents can acquire the requisite knowledge of stereotypes while resisting their pernicious influence, so long as that knowledge remains, in relevant contexts, relatively inaccessible.

In this paper, I defend a new theory of normative reasons called reasons as good bases, according to which a normative reason to φ is something that is a good basis for φing. The idea is that the grounds on which we do things—bases—can be better or worse as things of their kind, and a normative reason—a good reason—is something that is just a good instance of such a ground. After introducing RGB, I clarify what it is to be a (...) good basis, and argue that RGB has various attractive features: it has intuitive implications, makes good sense of the weights of reasons, and attractively explains the relationship between normative reasons and motivating reasons. I then briefly defend the view from objections and compare it to rivals. Finally, I sketch two possible implications of RGB: some kind of constitutivism, according to which the norms that govern us are explained by the nature of agency, and second, the claim that agents who do things for reasons generally do them for good reasons.

Intentionality, or the power of minds to be about, to represent, or to stand for things, remains central in the philosophy of mind. But the study of intentionality in the analytic tradition has been dominated by discussions of propositional attitudes such as belief, desire, and visual perception. There are, however, intentional states that aren't obviously propositional attitudes. For example, Indiana Jones fears snakes, Antony loves Cleopatra, and Jane hates the monster under her bed. The present paper explores such mental states (...) in an introductory but opinionated way. (shrink)

Moral philosophers are, among other things, in the business of constructing moral theories. And moral theories are, among other things, supposed to explain moral phenomena. Consequently, one’s views about the nature of moral explanation will influence the kinds of moral theories one is willing to countenance. Many moral philosophers are (explicitly or implicitly) committed to a deductive model of explanation. As I see it, this commitment lies at the heart of the current debate between moral particularists and moral generalists. In (...) this paper I argue that we have good reasons to give up this commitment. In fact, I show that an examination of the literature on scientific explanation reveals that we are used to, and comfortable with, non-deductive explanations in almost all areas of inquiry. As a result, I argue that we have reason to believe that moral explanations need not be grounded in exceptionless moral principles. (shrink)

Kyle Stanford has recently claimed to offer a new challenge to scientific realism. Taking his inspiration from the familiar Pessimistic Induction (PI), Stanford proposes a New Induction (NI). Contra Anjan Chakravartty’s suggestion that the NI is a ‘red herring’, I argue that it reveals something deep and important about science. The Problem of Unconceived Alternatives, which lies at the heart of the NI, yields a richer anti-realism than the PI. It explains why science falls short when it falls short, and (...) so it might figure in the most coherent account of scientific practice. However, this best account will be antirealist in some respects and about some theories. It will not be a sweeping antirealism about all or most of science. (shrink)

The article begins by describing two longstanding problems associated with direct inference. One problem concerns the role of uninformative frequency statements in inferring probabilities by direct inference. A second problem concerns the role of frequency statements with gerrymandered reference classes. I show that past approaches to the problem associated with uninformative frequency statements yield the wrong conclusions in some cases. I propose a modification of Kyburg’s approach to the problem that yields the right conclusions. Past theories of direct inference have (...) postponed treatment of the problem associated with gerrymandered reference classes by appealing to an unexplicated notion of projectability . I address the lacuna in past theories by introducing criteria for being a relevant statistic . The prescription that only relevant statistics play a role in direct inference corresponds to the sort of projectability constraints envisioned by past theories. (shrink)

Cognitivists about the emotions minimally hold that it is a necessary condition for being in an emotional state that one make a certain judgement or have a certain belief. For example, if I am angry with Sam, then I must believe that Sam has wronged me. Perhaps I must also elicit a certainly bodily response or undergo some relevant experience, but crucial to the view is the belief or judgement. In the face of ‘recalcitrant emotions’, this once very popular view (...) has come under heavy criticism that has led many theorists to either abandon the view or to offer more nuanced representational views of the emotions. Against what seems to now be received wisdom, I argue that cognitivists have tools at their disposal that allow them to alleviate the apparent conflicts presented by cases of recalcitrance. But I also believe that cognitivists are still in trouble. Although cognitivists have a range of underexplored resources, their use comes at a high cost. In particular, cognitivists must adopt a widespread and thoroughgoing inaccessibility to our own thoughts and judgements that should strike one as implausible. It is mental opacity rather than mental conflict that is the real problem posed by recalcitrance. (shrink)

Homeostatic property clusters (HPCs) are offered as a way of understanding natural kinds, especially biological species. I review the HPC approach and then discuss an objection by Ereshefsky and Matthen, to the effect that an HPC qua cluster seems ill-fitted as a description of a polymorphic species. The standard response by champions of the HPC approach is to say that all members of a polymorphic species have things in common, namely dispositions or conditional properties. I argue that this response fails. (...) Instances of an HPC kind need not all be similar in their exhibited properties. Instead, HPCs should instead be understood as unified by the underlying causal mechanism that maintains them. The causal mechanism can both produce and explain some systematic differences between a kind’s members. An HPC kind is best understood not as a single cluster of properties maintained in stasis by causal forces, but as a complex of related property clusters kept in relation by an underlying causal process. This approach requires recognizing that taxonomic systems serve both explanatory and inductive purposes. (shrink)

In this paper, I claim that extant empirical data do not support a radically embodied understanding of the mind but, instead, suggest (along with a variety of other results) a massively representational view. According to this massively representational view, the brain is rife with representations that possess overlapping and redundant content, and many of these represent other mental representations or derive their content from them. Moreover, many behavioral phenomena associated with attention and consciousness are best explained by the coordinated activity (...) of units with redundant content. I finish by arguing that this massively representational picture challenges the reliability of a priori theorizing about consciousness. (shrink)

When we ask what natural kinds are, there are two different things we might have in mind. The first, which I’ll call the taxonomy question, is what distinguishes a category which is a natural kind from an arbitrary class. The second, which I’ll call the ontology question, is what manner of stuff there is that realizes the category. Many philosophers have systematically conflated the two questions. The confusion is exhibited both by essentialists and by philosophers who pose their accounts in (...) terms of similarity. It also leads to misreading philosophers who do make the distinction. Distinguishing the questions allows for a more subtle understanding of both natural kinds and their underlying metaphysics. (shrink)

In this paper, I argue that theories of perception that appeal to Helmholtz’s idea of unconscious inference (“Helmholtzian” theories) should be taken literally, i.e. that the inferences appealed to in such theories are inferences in the full sense of the term, as employed elsewhere in philosophy and in ordinary discourse. -/- In the course of the argument, I consider constraints on inference based on the idea that inference is a deliberate acton, and on the idea that inferences depend on the (...) syntactic structure of representations. I argue that inference is a personal-level but sometimes unconscious process that cannot in general be distinguished from association on the basis of the structures of the representations over which it’s defined. I also critique arguments against representationalist interpretations of Helmholtzian theories, and argue against the view that perceptual inference is encapsulated in a module. (shrink)

The accepted narrative treats John Stuart Mill’s Kinds as the historical prototype for our natural kinds, but Mill actually employs two separate notions: Kinds and natural groups. Considering these, along with the accounts of Mill’s nineteenth-century interlocutors, forces us to recognize two distinct questions. First, what marks a natural kind as worthy of inclusion in taxonomy? Second, what exists in the world that makes a category meet that criterion? Mill’s two notions offer separate answers to the two questions: natural groups (...) for taxonomy and Kinds for ontology. This distinction is ignored in many contemporary debates about natural kinds and is obscured by the standard narrative that treats our natural kinds just as a development of Mill’s Kinds. (shrink)

There are two senses of ‘what scientists know’: An individual sense (the separate opinions of individual scientists) and a collective sense (the state of the discipline). The latter is what matters for policy and planning, but it is not something that can be directly observed or reported. A function can be defined to map individual judgments onto an aggregate judgment. I argue that such a function cannot effectively capture community opinion, especially in cases that matter to us.

Some philosophers understand natural kinds to be the categories which are constraints on enquiry. In order to elaborate the metaphysics appropriate to such an account, I consider the complicated history of scurvy, citrus, and vitamin C. It may be tempting to understand these categories in a shallow way (as mere property clusters) or in a deep way (as fundamental properties). Neither approach is adequate, and the case instead calls for middle-range ontology: starting from categories which we identify in the world (...) and elaborating their structure, but not pretending to jump ahead to a complete story about fundamental being.

Now it is plain that such consequences as these conflict sharply with common-sense notions of morality. If we had been obliged to accept Psychological Egoism, in any of its narrower forms, on its merits, we should have had to say: 'So much the worse for the common-sense notions of morality!' But, if I am right, the morality of common sense, with all its difficulties and incoherences, is immune at least to attacks from the basis of Psychological Egoism.

Those who want to deny the ‘ought implies can’ principle often turn to weakened views to explain ‘ought implies can’ phenomena. The two most common versions of such views are that ‘ought’ presupposes ‘can’, and that ‘ought’ conversationally implicates ‘can’. This paper will reject both views, and in doing so, present a case against any pragmatic view of ‘ought implies can’. Unlike much of the literature, I won't rely on counterexamples, but instead will argue that each of these views fails (...) on its own terms. ‘Ought’ and ‘can’ do not obey the negation test for presupposition, and they do not obey the calculability or the cancelability tests for conversational implicature. I diagnose these failures as partly a result of the importance of the contrapositive of ‘ought implies can’. I end with a final argument emphasizing the role the principle plays in moral thinking, and the fact that no pragmatic account can do it justice. (shrink)

The Argument from Inductive Risk (AIR) is taken to show that values are inevitably involved in making judgements or forming beliefs. After reviewing this conclusion, I pose cases which are prima facie counterexamples: the unreflective application of conventions, use of black-boxed instruments, reliance on opaque algorithms, and unskilled observation reports. These cases are counterexamples to the AIR posed in ethical terms as a matter of personal values. Nevertheless, it need not be understood in those terms. The values which load a (...) theory choice may be those of institutions or past actors. This means that the challenge of responsibly handling inductive risk is not merely an ethical issue, but is also social, political, and historical. (shrink)

This comment mainly examines Yli-Vakkuri and Hawthorne’s preferred framework for examining whether narrow content is viable, arguing that their framework is not well-suited to the task; once a more traditional framework is adopted, Y&H’s case against internalism is strengthened.

In a recent article, Joel Pust argued that direct inference based on reference properties of differing arity are incommensurable, and so direct inference cannot be used to resolve the Sleeping Beauty problem. After discussing the defects of Pust's argument, I offer reasons for thinking that direct inferences based on reference properties of differing arity are commensurable, and that we should prefer direct inferences based on logically stronger reference properties, regardless of arity.

The problem of underdetermination is thought to hold important lessons for philosophy of science. Yet, as Kyle Stanford has recently argued, typical treatments of it offer only restatements of familiar philosophical problems. Following suggestions in Duhem and Sklar, Stanford calls for a New Induction from the history of science. It will provide proof, he thinks, of “the kind of underdetermination that the history of science reveals to be a distinctive and genuine threat to even our best scientific theories” (Stanford 2001, (...) p. S12). This paper examines Stanford’s New Induction and argues that it – like the other forms of underdetermination that he criticizes – merely recapitulates familiar philosophical conundra. (shrink)

Standard Analytic Epistemology (SAE) names a contingently clustered class of methods and theses that have dominated English-speaking epistemology for about the past half-century. The major contemporary theories of SAE include versions of foundationalism, coherentism, reliabilism, and contextualism. While proponents of SAE don’t agree about how to define naturalized epistemology, most agree that a thoroughgoing naturalism in epistemology can’t work. For the purposes of this paper, we will suppose that a naturalistic theory of epistemology takes as its core, as its starting-point, (...) an empirical theory. The standard argument against naturalistic approaches to epistemology is that empirical theories are essentially descriptive, while epistemology is essentially prescriptive, and a descriptive theory cannot yield normative, evaluative prescriptions. In short, naturalistic theories cannot overcome the is-ought divide. Our main goal in this paper is to show that the standard argument against naturalized epistemology has it almost exactly backwards. (shrink)
