The study of biodiversity spans many disciplines and includes data pertaining to species distributions and abundances, genetic sequences, trait measurements, and ecological niches, complemented by information on collection and measurement protocols. A review of the current landscape of metadata standards and ontologies in biodiversity science suggests that existing standards such as the Darwin Core terminology are inadequate for describing biodiversity data in a semantically meaningful and computationally useful way. Existing ontologies, such as the Gene Ontology and others in the Open (...) Biological and Biomedical Ontologies (OBO) Foundry library, provide a semantic structure but lack many of the necessary terms to describe biodiversity data in all its dimensions. In this paper, we describe the motivation for and ongoing development of a new Biological Collections Ontology, the Environment Ontology, and the Population and Community Ontology. These ontologies share the aim of improving data aggregation and integration across the biodiversity domain and can be used to describe physical samples and sampling processes (for example, collection, extraction, and preservation techniques), as well as biodiversity observations that involve no physical sampling. Together they encompass studies of: 1) individual organisms, including voucher specimens from ecological studies and museum specimens, 2) bulk or environmental samples (e.g., gut contents, soil, water) that include DNA, other molecules, and potentially many organisms, especially microbes, and 3) survey-based ecological observations. We discuss how these ontologies can be applied to biodiversity use cases that span genetic, organismal, and ecosystem levels of organization. We argue that if adopted as a standard and rigorously applied and enriched by the biodiversity community, these ontologies would significantly reduce barriers to data discovery, integration, and exchange among biodiversity resources and researchers.

Several philosophers have recently claimed that if a proposition is cancellable from an uttered sentence then that proposition is not entailed by that uttered sentence. The claim should be a familiar one. It has become a standard device in the philosopher's tool-kit. I argue that this claim is false. There is a kind of entailment—which I call “modal entailment”—that is context-sensitive and, because of this, cancellable. So cancellability does not show that a proposition is not entailed by an uttered sentence. (...) I close the paper by describing an implication this has for a disagreement between J. L. Austin and Grice concerning the relation between felicity and truth. (shrink)

Many assume that theories of distributive justice must obviously take people’s lifetimes, and only their lifetimes, as the relevant period across which we distribute. Although the question of the temporal subject has risen in prominence, it is still relatively underdeveloped, particularly in the sphere of health and healthcare. This paper defends a particular view, “momentary sufficientarianism,” as being an important element of healthcare justice. At the heart of the argument is a commitment to pluralism about justice, where theorizing about just (...) principles demands paying attention to the role particular goods play in our lives. This means that different approaches to the temporal subject—as well as other relevant issues—may be appropriate for different goods, including different goods within healthcare. In particular, the paper discusses two central goods targeted by healthcare: life-saving and pain relief. The view is offered as complementary to, rather than competitive with, lifetime approaches. As such, the paper finishes by considering how a pluralist approach, which engages both with people’s lives as a whole and with their states at particular moments, can reconcile the potentially competing claims in healthcare that emerge from these two perspectives.

This essay argues that, despite the potential for an encounter between Stanley Cavell’s thought and found-footage experimental filmmaking, this has not yet taken place because the early Cavell’s picture of films as autonomous “wholes,” together with his "global-holistic" conception of modernism, prevented him from appreciating the expressive possibilities of filmic fragments. I then argue that these impediments to an encounter with found footage recede in Cavell’s later thought, as he moves away from a concern with modernism and as J. L. (...) Austin’s How to Do Things with Words comes to play a greater role in his film writing. In this late period, Cavell no longer conceives of topics of film criticism as filmic “wholes” but rather, more loosely, along the lines of what Austin called “total speech situations.” I claim that the culmination of this turn lies in Cavell’s writing on the expressive powers of collections. In closing, I demonstrate the possibilities of the late Cavell’s thinking about collections and “passionate utterances” for found-footage filmmaking by discussing Mexican experimental filmmaker Bruno Varela’s Monolito (2019), with particular attention to how Varela uses archival footage to fulfill the exigencies of finding new modes of expression at just the moment when a world is receding from view.

Uno dei principali problemi nello studio della mente e della sua "collocazione" consiste nell'identificazione del corretto Livello di Astrazione a cui le varie descrizioni fenomeniche e le corrispondenti ipotesi esplicative possono essere sviluppate e confrontate. L'articolo contribuisce all'attuale dibattito metodologico in filosofia della mente analizzando due nozioni fondative, quella di modello e quella di simulazione, sulla base del concetto di Livello di Astrazione. L'ambito è quello del Metodo delle Astrazioni, proposto in Floridi e Sanders [2003]. Il Metodo delle Astrazioni si (...) basa su una particolare branca dell'informatica teorica, quella dei Metodi Formali (Roever e Engelhardt [1998]; Woodcock e Davies [1996]), dove la matematica discreta è utilizzata per descrivere analiticamente le specifiche del comportamento di sistemi che elaborano informazioni. I sistemi sono descritti in termini di osservabili e regole di transizione, cioè come sistemi di transizione. Le descrizioni comportano l'utilizzo di variabili che rappresentano osservabili nella realtà, astraendo da altri eventuali osservabili. L'idea di fondo del Metodo delle Astrazioni è che tale processo di filtraggio sia ineliminabile in qualsiasi accesso alla realtà. Il tentativo di sondare un sistema in maggiore profondità produce una maggiore astrazione delle teorie e degli oggetti teorici che descrivono tale sistema. Il Metodo delle Astrazioni si presenta quindi come uno strumento per organizzare e chiarificare le varie teorie che intendono fornire una spiegazione della realtà o della conoscenza. La principale tesi dell'articolo è che "modello" e "simulazione" non possano essere pensati come nozioni a sé stanti, ma che la loro natura possa essere chiarita nei termini di tipi di relazioni tra sistemi di transizione. Nello specifico, si argomenta che la relazione di simulazione è una relazione tra gli osservabili di sistemi di transizione, mentre il modello è una relazione tra le regole di transizione di questi sistemi. Dati questi due nuovi tipi di relazioni, è possibile arricchire con ulteriori strutture di analisi il Metodo delle Astrazioni, estendendo la sua applicabilità. Queste strutture sono discusse nell'articolo come "Reti di Astrazione". (shrink)

The purpose of this study is exposition on the themes of method and mysticism in the work of Simone Weil. Nearly a decade before the onset of her first mystical experience, Weil developed a method to be rigorously applied in daily philosophical reflection. She outlines this method in her dissertation on Descartes (1929-1930). I examine the question of how Weil applied method to philosophical reflection on her mystical experiences (onset 1938-1939). I analyze Weil’s mystical experiences as a type of transformative (...) experience in L. A. Paul’s strict sense of the term. On Paul’s view, an experience is transformative if it is both epistemically and personally transformative. An experience is epistemically transformative if the only way to know what it is like to have it is to have it yourself. An experience is personally transformative if it changes your point of view, including your core preferences (Paul, 2014). I present a thought experiment and textual evidence to motivate the claim that Weil’s mystical experiences meet Paul’s conditions for transformative experience. I then propose two epistemological facts that can be revealed by philosophical reflection on mystical experience. First, it is possible to read meaning erroneously in the appearances of things. Second, it is possible to come to hold to the certainty of a conviction for reasons that elude the intellect. My findings suggest that Weil’s late views on philosophy accommodate these two epistemological constraints, thereby demonstrating a possible connection between Weil’s mystical experiences and her mature views on the nature, scope, and proper method of philosophy. However, my preliminary findings also suggest that Weil’s early work on method may have anticipated these epistemological obstacles prior to the onset of her first mystical experience. Thus, further exposition of Weil’s method is needed to support or elucidate the claim (Rozelle-Stone and Davis, 2021) that Weil’s epistemology underwent significant changes because of her mystical experiences.

J. Schauder introduced the notion of basis in a Banach space in 1927. If a Banach space has a basis then it is also separable. The problem whether every separable Banach space has a Schauder basis appeared for the first time in 1931 in Banach's book "Theory of Linear Operations". If a Banach space has a Schauder basis it also has the approximation property. A Banach space X has the approximation property if for every Banach space Y the finite rank (...) operators are dense in the closed subspace of all compact operators from Y to X. Both problems were solved in the negative in 1972 by Per Enflo. His proof was almost immediately simplified by A. M. Davie, who using a probabilistic lemma constructed a separable closed subspace of l_inifnity without the approximation property. In this thesis we present some of the equivalent properties to the approximation property due to A. Grothendieck, and we make a detailed exposition of the proof by A. M. Davie. (shrink)

Emphasizing the human body in all of its forms, Beauty Unlimited expands the boundaries of what is meant by beauty both geographically and aesthetically. Peg Zeglin Brand and an international group of contributors interrogate the body and the meaning of physical beauty in this multidisciplinary volume. This striking and provocative book explores the history of bodily beautification; the physicality of socially or culturally determined choices of beautification; the interplay of gender, race, class, age, sexuality, and ethnicity within and on the (...) body; and the aesthetic meaning of the concept of beauty in an increasingly globalized world.

PRINCÍPIOS DA DIGESTÃO DOS ALIMENTOS NOS BEZERROS -/- -/- E. I. C. da Silva -/- Departamento de Agropecuária – IFPE Campus Belo Jardim -/- Departamento de Zootecnia – UFRPE sede -/- -/- PRINCÍPIOS DA DIGESTÃO DOS ALIMENTOS NOS BEZERROS -/- -/- INTRODUÇÃO -/- Se todos os bezerros pudessem ser criados por suas mães, haveria pouca necessidade de inúmeros livros, artigos e trabalhos, como esse, sobre a criação e o manejo básico desses animais. A maioria das vacas desempenha um ótimo papel (...) na criação dos seus descendentes, desde que sejam tomados os devidos cuidados com relação a alimentação, saúde e a outros aspectos relativos à criação desses neonatos. A essência da pecuária bovina relativa à criação de bezerros é manter esses animais vivos e aptos o suficiente para desempenhar atividades produtivas de grande importância na propriedade. Para tanto, os criadores necessitam entender o desenvolvimento do trato digestivo do bezerro e os conceitos básicos da digestão dos alimentos por ele, e é isso que pretendo aclarar de forma clara e concisa com esse trabalho. -/- -/- 1.1 O TRATO DIGESTIVO DO BEZERRO -/- Um animal adulto necessita de quatro estômagos funcionais para dar-lhe a capacidade de utilizar a ampla gama de alimentos disponíveis. -/- O retículo e o rúmen abrigam milhões de micróbios que fermentam e digerem o material vegetal, em especial às presentes nas forragens. O omaso permite a absorção de água do conteúdo do intestino. O abomaso, ou quarto estômago, é o verdadeiro estômago, comparável ao dos humanos, e permite a digestão ácida dos alimentos. -/- O bezerro muito jovem não desenvolve a capacidade de digerir o pasto, sendo assim o abomaso é o único estômago funcional ao nascer. Tanto os animais recém-nascidos como os adultos têm um intestino delgado funcional que permite a digestão alcalina dos alimentos. -/- A figura 1 ilustra a anatomia dos estômagos e intestino delgado de um bezerro recém-nascido. Esse diagrama esquemático mostra as dimensões relativas dos quatro estômagos, o sulco esofágico, que vai do esôfago até o abomaso, e o esfíncter pilórico ou válvula no fundo do abomaso, que controla a velocidade de movimento do conteúdo do intestino no duodeno. -/- O omaso e o abomaso representam cerca de 70% da capacidade total do estômago no bezerro recém-nascido. Por outro lado, nas vacas adultas, eles compõem apenas 30% da capacidade total do estômago (figura 2). -/- A digestão dos alimentos é auxiliada pela secreção de certos produtos químicos denominados enzimas, que estão presentes nas várias partes do intestino. Por exemplo, os bezerros produzem a enzima renina na parede do abomasal para auxiliar na digestão das proteínas do leite, enquanto a lactase é produzida na parede do duodeno para a digestão do açúcar do leite (lactose). Estas enzimas operam mais eficazmente em diferentes níveis de acidez no conteúdo do intestino, ácido no abomaso e alcalino no duodeno. Para conseguir isso, o bezerro segrega eletrólitos, ou sais minerais, com as enzimas, para mudar o conteúdo do intestino de um tipo para outro. -/- Os produtos finais da digestão dos diferentes componentes dos alimentos são absorvidos através da parede do intestino, mediante as vilosidades intestinais, para a corrente sanguínea, onde são levados para as diferentes partes do corpo para o crescimento e desenvolvimento do animal. -/- -/- 1.2 O BEZERRO ALIMENTADO COM LEITE -/- O Leite ou substituto do leite, quer seja apreendido através de uma teta ou bebido de um balde, é canalizado do esôfago através do sulco esofágico para o abomaso. Este sulco é um pequeno canal na parede do rúmen que é controlado por músculos que permitem que os líquidos sejam diretamente enviados para o abomaso e que não entrem no rúmen. O sulco é ativado em resposta a diferentes estímulos. Funciona bem quando os bezerros amamentam-se através das tetas das mães, mas às vezes não funciona quando bebem de um balde. Essa parece ser uma condição psicológica em resposta aos bezerros separados de suas mães. A maioria dos bezerros podem ser treinados pelo tratador para beber o leite do balde rapidamente e bem, a metodologia empregada é a da persuasão do animal, ao qual o mesmo possa responder positivamente à nova rotina diária e à mãe substituta na forma do criador do bezerro. Quando o leite ou o substituto do leite entra no abomaso, forma um coágulo firme dentro de alguns minutos sob a influência das enzimas renina e pepsina. Este é o mesmo processo envolvido na fabricação de queijo ou junket, usando renina para coagular a proteína do leite. A coagulação do leite retarda a taxa em que flui para fora do abomaso, permitindo assim uma liberação constante de nutrientes alimentares em todo o intestino e, eventualmente, para a corrente sanguínea. Pode levar de 12 a 18 horas para que a coalhada de leite seja totalmente digerida. -/- As enzimas que atuam nas proteínas do leite requerem um ambiente ácido e esse é fornecido pela secreção do ácido clorídrico no abomaso. No entanto, até que a digestão ácida esteja operando de forma eficiente, e isso pode levar até sete dias, a única forma de proteína que pode ser digerida é a caseína. Não há substituto para a caseína no bezerro muito jovem. Os substitutos do leite que contêm outras formas de proteína não podem ser devidamente digeridos até que os bezerros sejam mais velhos. Logo, é necessário muito cuidado para não fornecer substitutos ou sucedâneos que contenham fontes proteicas que não possam ser digeridas pelo estômago do animal, para que não ocasione complicações gastrintestinais. -/- A digestão do leite pode ser melhorada com a inclusão de coalho, que pode ser obtido a partir de fábricas de queijo ou aditivos comerciais de leite de bezerro para a primeira semana ou mais. Esses produtos comerciais podem fornecer ácidos adicionais para reduzir o pH abomasal e incrementar a quantidade de enzimas e bactérias específicas para aumentar a taxa de degradação da coalhada de leite. Tais aditivos são chamados probióticos, na medida em que ajudam nos processos digestivos normais. A pesquisa nem sempre os encontrou para melhorar o desempenho e a saúde dos bezerros, e eles são mais propensos a ser benéficos quando os bezerros estão sofrendo de problemas de saúde. Além disso, a sua eficácia, em termos de custo-benefício é, por vezes, questionada. -/- Qualquer leite de uma alimentação anterior está envolvido neste coágulo recém-formado. As proteínas líquidas de soro de leite e a lactose são rapidamente separadas da coalhada de leite e passam para o abomaso. A gordura do leite contida na coalhada de leite é decomposta por outra enzima, a lipase. Esta é secretado na boca pela saliva e incorporada quando o leite é engolido. A alimentação pelas tetas em vez da alimentação através do balde parece produzir mais saliva e, portanto, mais lipase. A digestão adicional da proteína do leite e da gordura ocorre no duodeno com a ajuda das enzimas produzidas no pâncreas. -/- A lactose, que é rapidamente liberada da coalhada de leite no abomaso, é dividida em glicose e galactose e estas são absorvidas na corrente sanguínea para formar a principal fonte de energia para os bezerros jovens. -/- As gorduras são divididas em ácidos graxos e glicerol para absorção e uso como energia, enquanto as proteínas são divididas em aminoácidos e peptídeos para absorção e uso como fontes de proteína corporal. -/- O amido de cereais, por exemplo, é uma importante fonte de energia em bezerros mais velhos, mas esses animais, nas suas primeiras semanas de vida, não conseguem digerir o amido. -/- O abomaso não é ácido até que o bezerro tenha 1-2 dias de idade e isso apresenta vantagens e desvantagens. A principal vantagem é que as proteínas imunes no colostro não podem ser digeridas nesse compartimento estomacal, por isso são absorvidas na corrente sanguínea na mesma forma quando produzidas pela vaca. Isso garante o seu papel como anticorpos para proteger contra as doenças e infecções. A baixa acidez do conteúdo abomasal no bezerro recém-nascido constitui um risco potencial das bactérias (e provavelmente vírus) tomadas através da boca. Estes não serão mortos pela digestão ácida, sendo assim podem passar para os intestinos, onde podem fazer mal ao bezerro recém-nascido. -/- Todos os bezerros pegam bactérias nos primeiros dias de vida e isso é essencial para o desenvolvimento normal do rúmen (flora microbiana). No entanto, a primeira bactéria a colonizar o intestino também pode causar danos. Desde que o bezerro tenha bebido colostro, os anticorpos maternos podem controlar a propagação dessas bactérias mais nocivas. -/- O bezerro alimentado com leite deve, então, produzir uma digestão ácida no abomaso e uma digestão alcalina no duodeno. Isto é conseguido pela produção de eletrólitos na parede do intestino. -/- Bezerros que sofrem de escoriações devido a distúrbios nutricionais ou infecções bacterianas podem perder grandes quantidades de água e eletrólitos em suas fezes. Estes devem ser reabastecidos como parte do tratamento para as escoriações. -/- O colostro é o primeiro leite produzido por vacas recém-paridas. Além de fornecer nutrientes essenciais para a alimentação animal, fornece anticorpos maternos que permitem a transferência passiva de imunidade contra doenças. As recomendações para a alimentação com colostro serão abordadas brevemente em outro trabalho. -/- -/- 1.3 DESENVOLVIMENTO DO RÚMEN E O PROCESSO DE DESMAME -/- Quando os bezerros são desmamados, o custo da criação diminui acentuadamente. Os custos de alimentação são mais baixos, os insumos de trabalho são reduzidos e a incidência de problemas de saúde é menor. No sentido econômico, faz sentido desmamar os bezerros assim que for razoável. No entanto, o bezerro é forçado a sofrer várias mudanças dramáticas, a saber: -/-  A fonte primária de nutrientes muda de líquido para sólido. -/-  A quantidade de matéria seca que o bezerro recebe é reduzida. -/-  O bezerro deve adaptar-se de um tipo monogástrico a um ruminante de digestão, que inclui a fermentação de alimentos. -/-  Mudanças na habitação e no manejo muitas vezes ocorrem em torno do desmame, o que pode aumentar o estresse. -/- Ao nascer, o rúmen é uma parte pequena e estéril do intestino que, ao desmame deve se tornar o compartimento mais importante dos quatro estômagos. Deve aumentar em tamanho, atividade metabólica interna e fluxo sanguíneo externo. Os cinco requisitos para o desenvolvimento ruminal são: -/-  Estabelecimento de bactérias. -/-  Líquido. -/-  Saída de material (ação muscular). -/-  Capacidade absortiva do tecido. -/-  Substrato para permitir o crescimento bacteriano, tais como minerais reciclados, bem como nutrientes para alimentação. -/- Antes do consumo de alimentos sólidos, as bactérias existentes fermentam o cabelo ingerido, o estrato e o leite que flui do abomaso para o rúmen. A maior parte da água que entra no rúmen provém da água livre (água real não contida no leite ou na solução substituta do leite). O leite contornará o rúmen através do sulco esofágico, enquanto a água livre não. -/- O rúmen se desenvolve a partir de um órgão muito pequeno em bezerros recém-nascidos (1-2 L) para a parte mais importante do intestino (25-30 L) por 3 meses de idade. Ele pode aumentar muito rapidamente durante as primeiras semanas de vida, dado o manejo da alimentação direita. -/- O crescimento do rúmen ocorre apenas sob a influência dos produtos finais da digestão no mesmo, que resultam da fermentação de alimentos sólidos pelos micróbios presentes nesse compartimento. O desenvolvimento ocorre em grande parte através do crescimento das papilas ruminais (figura 5 e 6) na parede ruminal (estruturas semelhantes a folhas na superfície interna), que aumentam a área superficial do rúmen e, portanto, a sua capacidade de absorver estes produtos finais de digestão. Portanto, os concentrados favorecem melhor o desenvolvimento dessas papilas ruminais. Para tanto, é necessário, com um tempo, ir incrementando a dieta sólida gradativamente para que esses animais deixem de consumir o leite das vacas produtoras e possam alimentar-se de ração e pastagens, que é a finalidade da criação de bovinos, ou seja, criar animais com menor custo possível e engordá-los através de ração, mas principalmente de pastagens. -/- A capacidade do rúmen e a ingestão de alimentos sólidos estão intimamente relacionadas. O desenvolvimento do rúmen é muito lento em bezerros alimentados com grandes quantidades de leite. O leite satisfaz seus apetites para que eles não tenham fome suficiente para comer qualquer alimento sólido. Logo, é necessário diminuir paulatinamente o fornecedor do leite para esses animais, favorecendo a ingestão de alimentos sólidos e desenvolvendo o rúmen, estômago que digere as fibras das forragens e que os tona animais peculiares. -/- A ruminação pode ocorrer com cerca de 2 semanas de idade e é uma boa indicação de que o rúmen está se desenvolvendo. Alimentos sólidos, bem como a ruminação, estimulam a produção de saliva e isso fornece nutrientes como ureia e bicarbonato de sódio para produzir os substratos para o crescimento e desenvolvimento da flora bacteriana. -/- No desmame precoce, é importante limitar a quantidade de leite oferecida e a sua disponibilidade durante todo o dia. Também é essencial fornecer alimentos sólidos. Os grosseiros (de baixa ou alta qualidade) devem ser oferecidos em combinação com concentrados de alta qualidade. -/- O criador deve tomar cuidado com o fornecimento de alimentos como a ração farelada, uma vez que essa ração pode entrar pelas vias nasais e ocasionar complicações respiratórias; há alguns relatos de bezerros mortos após a ingestão de ração farelada, na autópsia de um dos casos foi diagnosticada uma morte por esses grãos farelados presentes no pulmão. Portanto, para evitar complicações o ideal é que se forneça uma ração denominada peletizada. -/- Os alimentos grosseiros (volumosos) estimulam o desenvolvimento do rúmen, enquanto os concentrados fornecem nutrientes para a alimentação animal que não são fornecidos pelas quantidades limitadas de leite oferecidas. Sem os concentrados, o crescimento dos bezerros é lento, mas o rúmen ainda se desenvolve, resultando em animais barrigudos. -/- A ureia fornece nitrogênio para os micróbios, enquanto o bicarbonato de sódio atua como um tampão ruminal, ajudando a manter um pH estável no conteúdo do rúmen. Isso é, particularmente, importante quando os bezerros comem grandes quantidades de grãos de cereais na vida adulta, pois os micróbios do rúmen podem produzir muito ácido lático durante a fermentação desse material. -/- Envenenamento por grãos ou acidose ocorre quando os níveis de ácido lático são excessivamente elevados e tornam-se tóxicos para os micróbios do rúmen e, eventualmente, para o animal. Assim como os produtos finais que são absorvidos através da parede do rúmen, a fermentação microbiana produz os gases dióxido de carbono e metano e estes são normalmente exalados. Quando algo impede a fuga destes gases do rúmen, o inchaço pode se manifestar em qualquer fase da vida, diz-se do animal estufado. -/- -/- 1.4 O PAPEL DA FORRAGEM NO PROCESSO DE DESMAME -/- Existem inúmeras controvérsias acerca do papel da forragem no processo de desmame. Pesquisas realizadas na década de 1980 indicaram claramente que a forragem era benéfica, enquanto pesquisas da década de 1990 descobriram que nem sempre era necessário o fornecimento da forragem para que os bezerros fossem desmamados e que não sofresse estresse e nem apresentasse baixa eficiência produtiva e reprodutiva no futuro. Na maioria das pesquisas anteriores, os bezerros eram desmamados com a oferta de concentrados moídos como pellets com ou sem a presença de feno longo ou palha. Porém, a inclusão de forragens na dieta melhorou a ingestão e o desempenho, além de permitir o desmame precoce. -/- Na pesquisa posterior, os bezerros geralmente alimentavam-se de concentrados grosseiramente moídos, além de alguns volumosos, enquanto alguns até incluíam volumosos picados finos na mistura (às vezes chamados de mistura muesli por apresentar o capim e a ração). Nesses estudos, verificou-se que a inclusão de feno ou palha adicional teve pouco efeito no desempenho pré-desmame. -/- Os sistemas de criação de bezerros australianos frequentemente diferem dos demais, especialmente em áreas de parto sazonais. Um número excessivo elevado de bezerros precisam ser criados de uma só vez para lhes fornecer, a todos, currais individuais durante todo o seu período de amamentação. Consequentemente, os bezerros são criados em grupos. Além disso, os ingredientes da maioria dos concentrados para esses animais são finamente moídos. Nessas situações, descobriu-se que a palha limpa é um alimento útil e que deve ser incluso no período pré-desmame. Alguns agricultores preferem feno de boa qualidade, porém estes agricultores geralmente têm bezerros em grupos muito pequenos, muitas vezes um ou dois, por isso possuem maior controle sobre a ingestão de forragem. -/- Figura 7: A alimentação volumosa de bezerros alimentados com leite é uma questão controversa. Imagem cedida pelo IPA -/- É difícil e, portanto, mais caro que os produtores de rações incorporem feno picado nas refeições dos bezerros. Os pellets são muito mais fáceis, pois eles vão fluir para silos. Por fim, os produtores de leite devem incluir o componente volumoso no regime alimentar pré-desmame. A pastagem não é a fonte ideal de forragem volumosa para os bezerros alimentados com leite, uma vez que possui muito pouca fibra e uma baixa densidade de energia alimentar. O seu elevado teor de água limita a sua capacidade de fornecer energia alimentar adequada aos animais em crescimento. Para ingerir a pastagem a capacidade ruminal deveria ser maior, bezerros jovens simplesmente não conseguem comer pasto suficiente, a menos que seja de alta em qualidade. -/- Os bezerros criados com leite e fornecimento gradual de concentrados apresentam uma boa função ruminal às 3 semanas de vida, além de possuírem uma suficiente capacidade ruminal para o desmame entre às 4-6 semanas de idade. No entanto, se a dieta for baseada em leite restrito e pastagem de alta qualidade, a capacidade do rúmen pode não ser suficiente para o desmame até às 8-10 semanas de vida. Mesmo assim, as taxas de crescimento seriam menores em bezerros desmamados com base alimentar somente à pasto, uma vez que a ingestão de energia é insuficiente devido às limitações físicas da capacidade ruminal. -/- Se a qualidade for muito boa e produza apetite, os bezerros preferem volumosos ao invés do concentrado, o que leva a uma ingestão reduzida de nutrientes durante alimentação, tendo como efeito um crescimento mais lento. Quando volumosos e concentrados fornecem apetite no animal, juntamente com o leite limitado, os bezerros podem comer cerca de 10% de palha e 90% de concentrados. Sem o volumoso e a ruminação resultante, o desenvolvimento do rúmen será mais lento devido à falta de saliva e produtos finais da digestão de fibras presentes na parede celular das forragens. -/- -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- -/- BEN ASHER, Aharon.

Different methodological approaches to empirical macroeconomics will be described and it will be explained that they represent different answers to the question from the title. Structural approaches require that macroeconometrical research should be explicitly founded on the (micro)economic theory in order to be able to measure the causal structure of the macroeconomic phenomena. Unstructural VAR approach suggest using econometric models to try to find out as much as possible about causal structure from the data, without prior restrictions from the theory. (...) Problems with both are described. (shrink)

Apart from what (little) OpenAI may be concealing from us, we all know (roughly) how ChatGPT works (its huge text database, its statistics, its vector representations, and their huge number of parameters, its next-word training, and so on). But none of us can say (hand on heart) that we are not surprised by what ChatGPT has proved to be able to do with these resources. This has even driven some of us to conclude that ChatGPT actually understands. It is not (...) true that it understands. But it is also not true that we understand how it can do what it can do. I will suggest some hunches about benign biases: convergent constraints that emerge at LLM scale that may be helping ChatGPT do so much better than we would have expected. These biases are inherent in the nature of language itself, at LLM scale, and they are closely linked to what it is that ChatGPT lacks, which is direct sensorimotor grounding to connect its words to their referents and its propositions to their meanings. These convergent biases are related to (1) the parasitism of indirect verbal grounding on direct sensorimotor grounding, (2) the circularity of verbal definition, (3) the mirroring of language production and comprehension, (4) iconicity in propositions at LLM scale, (5) computational counterparts of human categorical perception in category learning by neural nets, and perhaps also (6) a conjecture by Chomsky about the laws of thought. The exposition will be in the form of a dialogue with ChatGPT-4. (shrink)

Spanish version of essay on the film ¡Aoquic iez in Mexico! / ¡Ya México no existirá más! (Annalisa D. Quagliata Blanco, 2024).

When A utters a declarative sentence in a context to B, typically A can mean a proposition by the sentence, the sentence in context literally expresses a proposition, there are propositions A and B can agree the sentence literally expressed, and B can acquire knowledge from this testimonial exchange. In recent work on linguistic communication, each of these four platitudes has been challenged, and on the same basis: viz. on the ground that exactly which proposition the sentence expressed in context (...) is not discernible given the information provided by the context. I argue that, even if this is true, there will be propositional parts of the proposition expressed by the sentence in context which can be identified and that, consequently, the partial understanding afforded by the existence of such identifiable parts undermines the soundness of the arguments against the platitudes.

ABSTRACT It has become standard to conceive of metalinguistic disagreement as motivated by a form of negotiation, aimed at reaching consensus because of the practical consequences of using a word with one content rather than another. This paper presents an alternative motive for expressing and pursuing metalinguistic disagreement. In using words with given criteria, we betray our location amongst social categories or groups. Because of this, metalinguistic disagreement can be used as a stage upon which to perform a social identity. (...) The ways in which metalinguistic disagreements motivated in this way diverge in character from metalinguistic negotiations are described, as are several consequences of the existence of metalinguistic disagreements motivated in this way.

The vast literature on negative treatment of outgroups and favoritism toward ingroups provides many local insights but is largely fragmented, lacking an overarching framework that might provide a unified overview and guide conceptual integration. As a result, it remains unclear where different local perspectives conflict, how they may reinforce one another, and where they leave gaps in our knowledge of the phenomena. Our aim is to start constructing a framework to help remedy this situation. We first identify a few key (...) ideas for creating a theoretical roadmap for this complex territory, namely the principles of etiological functionalism and the dual inheritance theory of human evolution. We show how a “molecular” approach to emotions fits into this picture, and use it to illuminate emotions that shape intergroup relations. Finally, we weave the pieces together into the beginnings of a systematic taxonomy of the emotions involved in social interactions, both hostile and friendly. While it is but a start, we have developed the argument in a way that illustrates how the foundational principles of our proposed framework can be extended to accommodate further cases. (shrink)

The usual way to try to ground knowing according to contemporary theory of knowledge is: We know something if (1) it’s true, (2) we believe it, and (3) we believe it for the “right” reasons. Floridi proposes a better way. His grounding is based partly on probability theory, and partly on a question/answer network of verbal and behavioural interactions evolving in time. This is rather like modeling the data-exchange between a data-seeker who needs to know which button to press on (...) a food-dispenser and a data-knower who already knows the correct number. The success criterion, hence the grounding, is whether the seeker’s probability of lunch is indeed increasing (hence uncertainty is decreasing) as a result of the interaction. Floridi also suggests that his philosophy of information casts some light on the problem of consciousness. I’m not so sure. (shrink)

This chapter has two aims. First, I distinguish between two forms of testimonial injustice: identity-based testimonial injustice and content-based testimonial injustice. Second, I utilize this distinction to develop a partial explanation for the persistent lack of diverse practitioners in academic philosophy. Specifically, I argue that both identity-based and content-based testimonial injustice are prevalent in philosophical discourse and that this prevalence introduces barriers to participation for those targeted. As I show, the dual and compounding effects of identity-based and content-based testimonial injustice (...) in philosophy plausibly contribute to a lack of diversity in the social identities of practitioners and the discourses in which practitioners are engaged.

What considerations place genuine constraints on an adequate semantics for normative and evaluative expressions? Linguists recognize facts about ordinary uses of such expressions and competent speakers’ judgments about which uses are appropriate. The contemporary literature reflects the widespread assumption that linguists don’t rely upon an additional source of data—competent speakers’ judgments about possible disagreement with hypothetical speech communities. We have several good reasons to think that such judgments are not probative for semantic theorizing. Therefore, we should accord these judgments no (...) probative value for the development of a semantics for our moral terms. Such judgments can no longer be presumed to put pressure on theories according to which our moral expressions share a semantics with ordinary, descriptive terms. Many rivals to pure, Descriptivist theories count among their advantages the ability to accommodate these judgments. If these judgments have no probative value, such theories lose an important source of support. (shrink)

Historically, laws and policies to criminalize drug use or possession were rooted in explicit racism, and they continue to wreak havoc on certain racialized communities. We are a group of bioethicists, drug experts, legal scholars, criminal justice researchers, sociologists, psychologists, and other allied professionals who have come together in support of a policy proposal that is evidence-based and ethically recommended. We call for the immediate decriminalization of all so-called recreational drugs and, ultimately, for their timely and appropriate legal regulation. We (...) also call for criminal convictions for nonviolent offenses pertaining to the use or possession of small quantities of such drugs to be expunged, and for those currently serving time for these offenses to be released. In effect, we call for an end to the “war on drugs.”. (shrink)

It is often thought that traditional recidivism prediction tools used in criminal sentencing, though biased in many ways, can straightforwardly avoid one particularly pernicious type of bias: direct racial discrimination. They can avoid this by excluding race from the list of variables employed to predict recidivism. A similar approach could be taken to the design of newer, machine learning-based (ML) tools for predicting recidivism: information about race could be withheld from the ML tool during its training phase, ensuring that the (...) resulting predictive model does not use race as an explicit predictor. However, if race is correlated with measured recidivism in the training data, the ML tool may ‘learn’ a perfect proxy for race. If such a proxy is found, the exclusion of race would do nothing to weaken the correlation between risk (mis)classifications and race. Is this a problem? We argue that, on some explanations of the wrongness of discrimination, it is. On these explanations, the use of an ML tool that perfectly proxies race would (likely) be more wrong than the use of a traditional tool that imperfectly proxies race. Indeed, on some views, use of a perfect proxy for race is plausibly as wrong as explicit racial profiling. We end by drawing out four implications of our arguments. (shrink)

Most people who defend physician-assisted death (PAD) endorse the Joint View, which holds that two conditions—autonomy and welfare—must be satisfied for PAD to be justified. In this paper, we defend an Autonomy Only view. We argue that the welfare condition is either otiose on the most plausible account of the autonomy condition, or else is implausibly restrictive, particularly once we account for the broad range of reasons patients cite for desiring PAD, such as “tired of life” cases. Moreover, many of (...) the common objections to an Autonomy Only view fail once we understand the extent of the autonomy condition’s requirements—in particular, the importance of one’s values for autonomous choices. If our view is correct, then the scope of permissible PAD is broader than is currently accepted in both the philosophical literature and the law, and therefore poses an important challenge to this widely accepted view on justified PAD.

There is significant controversy over whether patients have a ‘right not to know’ information relevant to their health. Some arguments for limiting such a right appeal to potential burdens on others that a patient’s avoidable ignorance might generate. This paper develops this argument by extending it to cases where refusal of relevant information may generate greater demands on a publicly funded healthcare system. In such cases, patients may have an ‘obligation to know’. However, we cannot infer from the fact that (...) a patient has an obligation to know that she does not also have a right not to know. The right not to know is held against medical professionals at a formal institutional level. We have reason to protect patients’ control over the information that they receive, even if in individual instances patients exercise this control in ways that violate obligations. (shrink)

This paper resolves a paradox concerning colour constancy. On the one hand, our intuitive, pre-theoretical concept holds that colour constancy involves invariance in the perceived colours of surfaces under changes in illumination. On the other, there is a robust scientific consensus that colour constancy can persist in cerebral achromatopsia, a profound impairment in the ability to perceive colours. The first stage of the solution advocates pluralism about our colour constancy capacities. The second details the close relationship between colour constancy and (...) contrast. The third argues that achromatopsics retain a basic type of colour constancy associated with invariants in contrast processing. The fourth suggests that one person-level, conscious upshot of such processing is the visual awareness of chromatic contrasts ‘at’ the edges of surfaces, implicating the ‘colour for form’ perceptual function. This primitive type of constancy sheds new light on our most basic perceptual capacities, which mark the lower borders of representational mind. (shrink)

The orthodox monadic determination thesis holds that we represent colour relations by virtue of representing colours. Against this orthodoxy, I argue that it is possible to represent colour relations without representing any colours. I present a model of iconic perceptual content that allows for such primitive relational colour representation, and provide four empirical arguments in its support. I close by surveying alternative views of the relationship between monadic and relational colour representation.

I introduce a distinction between health need and medical need, and raise several questions about their interaction. Health needs are needs that relate directly to our health condition. Medical needs are needs which bear some relation to medical institutions or processes. I suggest that the question of whether medical insurance or public care should cover medical needs, health needs, or only needs which fit both categories is a political question that cannot be resolved definitionally. I also argue against an overly (...) strict definition of medical need on the grounds that this presupposes, wrongly, that medical intervention should always be a last resort. (shrink)

There is an ongoing increase in the use of mobile health technologies that patients can use to monitor health-related outcomes and behaviours. While the dominant narrative around mHealth focuses on patient empowerment, there is potential for mHealth to fit into a growing push for patients to take personal responsibility for their health. I call the first of these uses ‘medical monitoring’, and the second ‘personal health surveillance’. After outlining two problems which the use of mHealth might seem to enable us (...) to overcome—fairness of burdens and reliance on self-reporting—I note that these problems would only really be solved by unacceptably comprehensive forms of personal health surveillance which applies to all of us at all times. A more plausible model is to use personal health surveillance as a last resort for patients who would otherwise independently qualify for responsibility-based penalties. However, I note that there are still a number of ethical and practical problems that such a policy would need to overcome. The prospects of mHealth enabling a fair, genuinely cost-saving policy of patient responsibility are slim. (shrink)

Some stories of moral exemplars motivate us to emulate their admirable attitudes and behaviors, but why do some exemplars motivate us more than others? We systematically studied how motivation to emulate is influenced by the similarity between a reader and an exemplar in social or cultural background (Relatability) and how personally costly or demanding the exemplar’s actions are (Attainability). Study 1 found that university students reported more inspiration and related feelings after reading true stories about the good deeds of a (...) recent fellow alum, compared to a famous moral exemplar from decades past. Study 2A developed a battery of short moral exemplar stories that more systematically varied Relatability and Attainability, along with a set of non-moral exemplar stories for comparison. Studies 2B and 2C examined the path from the story type to relatively low stakes altruism (donating to charity and intentions to volunteer) through perceived attainability and relatability, as well as elevation and pleasantness. Together, our studies suggest that it is primarily the relatability of the moral exemplars, not the attainability of their actions, that inspires more prosocial motivation, at least regarding acts that help others at a relatively low cost to oneself.

This article is a rebuttal to Robert G. Cavin and Carlos A. Colombetti’s article, “Assessing the Resurrection Hypothesis: Problems with Craig’s Inference to the Best Explanation,” which argues that the Standard Model of current particle physics entails that non-physical things (like a supernatural God or a supernaturally resurrected body) can have no causal contact with the physical universe. As such, they argue that William Lane Craig’s resurrection hypothesis is not only incompatible with the notion of Jesus physically appearing to the (...) disciples, but the resurrection hypothesis is significantly limited in both its explanatory scope and explanatory power. This article seeks to demonstrate why their use of the Standard Model does not logically entail a rejection of the physical resurrection of Jesus when considering the scope and limitations of science itself.

In this paper, I defend the agent/patient distinction against critics who argue that causal interactions are symmetrical. Specifically, I argue that there is a widespread type of causal interaction between distinct entities, resulting in a type of ontological asymmetry that provides principled grounds for distinguishing agents from patients. The type of interaction where the asymmetry is found is when one of the entities undergoes a change in kind, structure, powers, or intrinsic properties as a result of the interaction while the (...) other does not. Interactions of this type are widespread in molecular biology and chemistry. I focus specifically on (i) the actions of enzymes on substrates and (ii) water molecules breaking the bonds of polarized molecules. Finally, I respond to objections by laying out and to a limited extent defending three commitments of my account: emergent entities and powers, realism about chemical kinds or structures, and the assumption of the agent/patient distinction in functional attributions in biology.

The idea of using responsibility in the allocation of healthcare resources has been criticized for, among other things, too readily abandoning people who are responsible for being very badly off. One response to this problem is that while responsibility can play a role in resource allocation, it cannot do so if it will leave those who are responsible below a “sufficiency” threshold. This paper considers first whether a view can be both distinctively sufficientarian and allow responsibility to play a role (...) even for those who will be left with very poor health. It then draws several further distinctions that may affect the application of responsibility at this level. We conclude that a more plausible version of the sufficientarian view is to allow a role for responsibility where failure to do so will leave someone else who is not responsible below the sufficiency threshold. However, we suggest that individuals must exhibit “sufficient responsibility” in order for this to apply, involving both a sufficient level of control and an avoidable failure to respond adequately to reasons for action.

This article presents a semantic analysis of indirect speech reports. The analysis aims to explain a combination of two phenomena. First, there are true utterances of sentences of the form α said that φ which are used to report an utterance u of a sentence wherein φ's content is not u's content. This implies that in uttering a single sentence, one can say several things. Second, when the complements of these reports (and indeed, these reports themselves) are placed in conjunctions, (...) the conjunctions are typically infelicitous. I argue that this combination of phenomena can be explained if speech reports report (perhaps contingent) parts of the contents of the sentences reported. (shrink)

Response to commentaries on 'The right not to know and the obligation to know'.

The Uniform Determination of Death Act (UDDA) provides that “an individual who has sustained either (1) irreversible cessation of circulatory and respiratory functions or (2) irreversible cessation of all functions of the entire brain, including the brain stem, is dead.” We show that the UDDA contains two conflicting interpretations of the phrase “cessation of functions.” By one interpretation, what matters for the determination of death is the cessation of spontaneous functions only, regardless of their generation by artificial means. By the (...) other, what matters is the cessation of both spontaneous and artificially supported functions. Because each UDDA criterion uses a different interpretation, the law is conceptually inconsistent. A single consistent interpretation would lead to the conclusion that conscious individuals whose respiratory and circulatory functions are artificially supported are actually dead, or that individuals whose brain is entirely and irreversibly destroyed may be alive. We explore solutions to mitigate the inconsistency. (shrink)

Faithful persons tend to relate to their religious beliefs as truth claims, particularly inasmuch as their beliefs have soteriological implications for those of different religions. For Christians the particular claims which matter most in this regard are those made by Jesus of Nazareth and his claims are primarily relational in nature. I propose a model in which we understand divine grace from Jesus as being mediated through relational knowledge of him on a compassionately exclusivist basis, including post-mortem. Supporting this model, (...) I draw from Eleonore Stump’s hypothesis in her 2018 Atonement that the crucifixion of Jesus opens the divine psyche to all human psyches sufficiently for salvific mutual indwelling to occur, and from Gavin D’Costa’s conception of the descensus Christi ad inferos as the mechanism for grace’s accessibility post-mortem presented in his 2009 Christianity and World Religions. This model seeks to address ongoing, justified pastoral concern for the soteriological status of non-Christians while still treating Christianity as objectively true. (shrink)

Here we focus on two questions: What is the proper semantics for deontic modal expressions in English? And what is the connection between true deontic modal statements and normative reasons? Our contribution towards thinking about the first, which makes up the bulk of our paper, considers a representative sample of recent challenges to a Kratzer-style formal semantics for modal expressions, as well as the rival views—Fabrizio Cariani’s contrastivism, John MacFarlane’s relativism, and Mark Schroeder’s ambiguity theory—those challenges are thought to motivate. (...) These include the Professor Procrastinate challenge to Inheritance (the principle that ‘If ought p and p entails q, then ought q), as well as Parfit’s miners puzzle regarding information-sensitive deontic modals. Here we argue that a Kratzer-style view is able to meet all of the challenges we’ll consider. In addition, we’ll identify challenges for each of those rival views. Our overall conclusion is that a Kratzer-style semantics remains the one to beat. With this assumption in place, we then ask how we should understand the relationship between true deontic modal statements and normative reasons. Should, for example, we hold that the truth of such a statement entails the existence of a normative reason for some agent to comply? Here we argue that, in many cases, acceptance of Kratzer’s semantics for deontic modals leaves open for substantive normative theorizing the question of whether an agent has a normative reason to comply with what she ought to do.

Most of us believe that partiality applies in a broad range of relationships. One relationship on which there is much disagreement is co-nationality. Some writers argue that co-national partiality is not justified in certain cases, like killing in war, since killing in defense of co-nationals is intuitively impermissible in other contexts. I argue that this approach overlooks an important structural feature of partiality—namely, that its scope is sometimes restricted. In this essay, I show how some relationships that generate reasons of (...) partiality are restricted in scope—that is, they generate reasons within particular contexts or with respect to particular goods. I then argue that co-national partiality is scope restricted. I then show how this fact helps proponents of co-national partiality overcome the aforementioned objection to its application in cases like war. (shrink)

To the question whether Hume believed in mind-independent physical objects (or as he would put it, bodies), the answer is Yes and No. It is Yes when Hume writes “We may well ask, What causes induce us to believe in the existence of body? but ’tis in vain to ask, Whether there be body or not? That is a point, which we must take for granted in all our reasonings.” However the answer is No after inquiring into the causes of (...) that belief, when he writes, “What then can we look for from this confusion of groundless and extraordinary opinions but error and falsehood? And how can we justify to ourselves any belief we repose in them?” My view is that Hume’s Yes and No answers can best be accounted for by seeing him as a Pyrrhonian skeptic in the tradition of Sextus Empiricus. This interpretation, while finding considerable truth in the various positions canvassed, is closest to those of Norton, Fogelin, and especially Popkin. (shrink)
