In this paper I develop three different arguments against the thesis that knowledge-how is a kind of knowledge-that. Knowledge-that is widely thought to be subject to an anti-luck condition, a justified or warranted belief condition, and a belief condition, respectively. The arguments I give suggest that if either of these standard assumptions is correct then knowledge-how is not a kind of knowledge-that. In closing I identify a possible alternative to the standard Rylean and intellectualist accounts of knowledge-how. This alternative view (...) illustrates that even if the arguments given here succeed it might still be reasonable to hold that knowing how to do something is a matter of standing in an intentional relation to a proposition other than the knowledge-that relation.

How should intellectualists respond to apparent Gettier-style counterexamples? Stanley offers an orthodox response which rejects the claim that the subjects in such scenarios possess knowledge-how. I argue that intellectualists should embrace a revisionary response according to which knowledge-how is a distinctively practical species of knowledge-that that is compatible with Gettier-style luck.

It is often said that ‘what it is like’-knowledge cannot be acquired by consulting testimony or reading books [Lewis 1998; Paul 2014; 2015a]. However, people also routinely consult books like What It Is Like to Go to War [Marlantes 2014], and countless ‘what it is like’ articles and youtube videos, in the apparent hope of gaining knowledge about what it is like to have experiences they have not had themselves. This article examines this puzzle and tries to solve it by (...) appealing to recent work on knowing-wh ascriptions. In closing I indicate the wider significance of these ideas by showing how they can help us to evaluate prominent arguments by Paul [2014; 2015a] concerning transformative experiences. (shrink)

This article examines the method of reflective equilibrium (RE) and its role in philosophical inquiry. It begins with an overview of RE before discussing some of the subtleties involved in its interpretation, including challenges to the standard assumption that RE is a form of coherentism. It then evaluates some of the main objections to RE, in particular, the criticism that this method generates unreasonable beliefs. It concludes by considering how RE relates to recent debates about the role of intuitions in (...) philosophy. (shrink)

This chapter examines some key developments in discussions of the social dimensions of knowing-how, focusing on work on the social function of the concept of knowing-how, testimony, demonstrating one's knowledge to other people, and epistemic injustice. I show how a conception of knowing-how as a form of 'downstream knowledge' can help to unify various phenomena discussed within this literature, and I also consider how these ideas might connect with issues concerning wisdom, moral knowledge, and moral testimony.

This chapter explores the relationship between knowing-how and skill, as well other success-in-action notions like dispositions and abilities. I offer a new view of knowledge-how which combines elements of both intellectualism and Ryleanism. According to this view, knowing how to perform an action is both a kind of knowing-that (in accord with intellectualism) and a complex multi-track dispositional state (in accord with Ryle’s view of knowing-how). I argue that this new view—what I call practical attitude intellectualism—offers an attractive set of (...) solutions to various puzzles concerning the connections between knowing-how and abilities and skills to perform intentional actions.

Paul (2014, 2015a) argues that one cannot rationally decide whether to have a transformative experience by trying to form judgments, in advance, about (i) what it would feel like to have that experience, and (ii) the subjective value of having such an experience. The problem is if you haven’t had the experience then you cannot know what it is like, and you need to know what it is like to assess its value. However, in earlier work I argued that ‘what (...) it is like’-knowledge comes in degrees, and I briefly suggested that, consequently, some instances of Paul’s argument schema might commit a fallacy of equivocation. The aim of this paper is to further explore and strengthen this objection by, first, offering a new argument—the modelling argument—in support of it, and then by evaluating a range of replies that might be given to this objection on Paul’s behalf. I conclude that each reply either fails or, at best, only partially succeeds in defending some but not all instances of Paul’s argument schema. In closing, I consider how we might revise Paul’s concepts of transformative experiences and choices in response to this conclusion. (shrink)

Hawley introduced the idea of the client's perspective on knowledge, which she used to illuminate knowing-how and cases of epistemic injustice involving knowing-how. In this paper, I explore how Hawley's idea might be used to illuminate not only knowing-how, but other forms of knowledge that, like knowing-how, are often claimed to be distinct from mere knowing-that, focusing on the case studies of moral understanding and ‘what it is like’-knowledge.

Knowledge-how often appears to be more difficult to transmit by testimony than knowledge-that and knowledge-wh. Some philosophers have argued that this difference provides us with an important objection to intellectualism—the view that knowledge-how is a species of knowledge-that. This article defends intellectualism against these testimony-based objections.

Is there a successful regress argument against intellectualism? In this article I defend the negative answer. I begin by defending Stanley and Williamson's (2001) critique of the contemplation regress against Noë (2005). I then identify a new argument – the employment regress – that is designed to succeed where the contemplation regress fails, and which I take to be the most basic and plausible form of a regress argument against intellectualism. However, I argue that the employment regress still fails. Drawing (...) on the previous discussion, I criticise further regress arguments given by Hetherington (2006) and Noë (2005). (shrink)

There is an intimate relationship between our experiences and our knowledge of what it is like to have those experiences. For having an experience of Φ-ing is clearly an important way of coming to know what it is Φ, and some philosophers have even suggested that it is the only way of coming to possess such knowledge. But despite this intimate connection, we often possess WIL-knowledge after any generating experience has ended. How is this possible? One popular suggestion, roughly following (...) David Lewis, is that one retains knowledge of what it is like to Φ in virtue of retaining abilities to imagine, remember, and recognise experiences of Φ-ing. In this chapter, my aim is to clarify and update this retention hypothesis, by showing how it is independent from Lewis’ ability hypothesis (according to which WIL-knowledge is identified with these abilities), and by identifying and resolving certain ambiguities involved in interpreting Lewis’ three ability conditions, especially the ability to imagine condition. I also explore issues concerning the relative priority of these three conditions, and I argue that there is a good sense in which the ability to imagine condition is the most important of these conditions with respect to how we conceptualise and ascribe WIL-knowledge.

This paper addresses the field of economic measurements of the value of assets, carried out by the methods of independent expert evaluation. The mathematical principles of application, within a comparative methodical approach, of additive and multiplicative models for correcting the cost of single indicator of compared objects have been considered. The differences of mathematical basis of the compared models were analyzed. It has been shown that the ambiguity in the methodology of correction procedure requires studying the advantages and disadvantages of (...) known models, as well as the justification and elaboration of recommendations for their application. Possible forms of correction representation using several alternative units of measurement have been defined; formulas for their interconnection have been built. Analytic expressions have been derived that mathematically describe the algorithms for performing the evaluation correction procedure using various forms of correction representation. The influence of the correction execution model on the characteristics of uncertainty in the independent evaluation result has been analyzed. The scope of two possible types of correction introduction models has been determined. A specific numerical example was used to demonstrate the methodological advantages of using a multiplicative model when summarizing percentage corrections. The independence of the correction result on the sequence of correction introduction has been confirmed. It is proposed to use the selected measure of partial corrections as a criterion for the adequacy of the correction introduction model. It is proved that the result of the independent expert evaluation depends on the chosen model and does not depend on the sequence of correction introduction. The reported study results are important in terms of theory and practice since they make it possible to improve the accuracy and reliability of the result of independent expert evaluation. (shrink)

What is the relationship between the linguistic properties of knowledge-how ascriptions and the nature of knowledge-how itself? In this chapter I address this question by examining the linguistic methodology of Stanley and Williamson (2011) and Stanley (2011a, 2011b) who defend the intellectualist view that knowledge-how is a kind of knowledge-that. My evaluation of this methodology is mixed. On the one hand, I defend Stanley and Williamson (2011) against critics who argue that the linguistic premises they appeal to—about the syntax and (...) semantics of knowledge-how and knowledge-wh ascriptions—do not establish their desired conclusions about the nature of knowledge-how itself. But, on the other hand, I also criticize the role that linguistic considerations play in Stanley’s (2011a) response to apparent Gettier-style counterexamples to intellectualism. (shrink)

I argue that the contemporary interplay of cosmology and particle physics in their joint effort to understand the processes at work during the first moments of the big bang has important implications for understanding the nature of lawhood. I focus on the phenomenon of spontaneous symmetry breaking responsible for generating the masses of certain particles. This phenomenon presents problems for the currently fashionable Dretske-Tooley-Armstrong theory and strongly favors a rival nomic ontology of causal powers.

This commentary suggests that the ongoing malaise of biomedical research results from adopting a doctrine that is incompatible with the principles of creative scientific discovery and thus should be treated as a mental rather than somatic disorder. I overview the progression of the malaise, outline the doctrine and the history of its marriage to science, formulate the diagnosis, justify it by reviewing the symptoms of the malaise, and suggest how to begin to cure the disease.

Many philosophers accept a view – what I will call the intuition picture – according to which intuitions are crucial evidence in philosophy. Recently, Williamson has argued that such views are best abandoned because they lead to a psychologistic conception of philosophical evidence that encourages scepticism about the armchair judgements relied upon in philosophy. In this paper I respond to this criticism by showing how the intuition picture can be formulated in such a way that: it is consistent with a (...) wide range of views about not only philosophical evidence but also the nature of evidence in general, including Williamson's famous view that E = K; it can maintain the central claims about the nature and role of intuitions in philosophy made by proponents of the intuition picture; it does not collapse into Williamson's own deflationary view of the nature and role of intuitions in philosophy; and it does not lead to scepticism.

The present essay took as its hypothesis the premise that the Metaphysical Neutrality proposed by Husserl since his initial studies needs to be recognized with methodological and analytical limits. In order to overcome this limit, a recovery of the Metaphysics and Theory of Knowledge of St. Thomas Aquinas was carried out, interpreting this theory through a Moderate and Direct Realism. As a conclusion, it was possible to identify that there is a very important similarity between both theories, as well as (...) that for phenomenological investigations to achieve their primary cognitive intent, care must be taken not to annihilate moderate realist metaphysics.

A proposed plan to rescue US biomedical research from its current ‘malaise’ will not be effective as it misdiagnoses the root cause of the disease.

Often philosophers have reason to ask fundamental questions about the aims, methods, nature, or value of their own discipline. When philosophers systematically examine such questions, the resulting work is sometimes referred to as “metaphilosophy.” Metaphilosophy, it should be said, is not a well-established, or clearly demarcated, field of philosophical inquiry like epistemology or the philosophy of art. However, in the late 20th and early 21st centuries there has been a great deal of metaphilosophical work on issues concerning the methodology of (...) philosophy in the analytic tradition. This article focuses on that work. (shrink)

The success of deep learning in natural language processing raises intriguing questions about the nature of linguistic meaning and ways in which it can be processed by natural and artificial systems. One such question has to do with subword segmentation algorithms widely employed in language modeling, machine translation, and other tasks since 2016. These algorithms often cut words into semantically opaque pieces, such as ‘period’, ‘on’, ‘t’, and ‘ist’ in ‘period|on|t|ist’. The system then represents the resulting segments in a dense (...) vector space, which is expected to model grammatical relations among them. This representation may in turn be used to map ‘period|on|t|ist’ (English) to ‘par|od|ont|iste’ (French). Thus, instead of being modeled at the lexical level, translation is reformulated more generally as the task of learning the best bilingual mapping between the sequences of subword segments of two languages; and sometimes even between pure character sequences: ‘p|e|r|i|o|d|o|n|t|i|s|t’ → ‘p|a|r|o|d|o|n|t|i|s|t|e’. Such subword segmentations and alignments are at work in highly efficient end-to-end machine translation systems, despite their allegedly opaque nature. The computational value of such processes is unquestionable. But do they have any linguistic or philosophical plausibility? I attempt to cast light on this question by reviewing the relevant details of the subword segmentation algorithms and by relating them to important philosophical and linguistic debates, in the spirit of making artificial intelligence more transparent and explainable.

In this thesis I examine the view—known as intellectualism—that knowledge-how is a kind of knowledge-that, or propositional knowledge. I examine issues concerning both the status of this view of knowledge-how and the philosophical implications if it is true. The ability hypothesis is an important position in the philosophy of mind that appeals to Gilbert Ryle’s famous idea that there is a fundamental distinction between knowledge-how and knowledge-that. This position appears to be inconsistent with the truth of intellectualism. However, I demonstrate (...) in this thesis that the ability hypothesis can be restated using the intellectualist view of knowledge-how. With regards to the status of intellectualism, I argue that the two main traditional arguments against intellectualism do not succeed. I also provide new and, I claim, successful arguments against intellectualism. These arguments point to a new view of knowledge-how that is distinct from both the standard intellectualist and Rylean views of knowledge-how. (shrink)

What kind of knowledge does one have when one knows what it is like to, say, fall in love, eat vegemite™, be a parent, or ride a bike? This Element addresses this question by exploring the tension between two plausible theses about this form of knowledge: (i) that to possess it one must have had the corresponding experience, and (ii) that to possess it one must know an answer to the 'what it is like' question. The Element shows how the (...) tension between these two theses helps to explain existing debates about this form of knowledge, as well as puzzling conflicts in our attitudes towards the possibility of sharing this knowledge through testimony, or other sources like literature, theories, and simulations. The author also offers a view of 'what it is like' knowledge which can resolve both the tension between (i) and (ii), and these puzzles around testimony. (shrink)

Neural machine translation (NMT) is one of the success stories of deep learning and artificial intelligence. Revolutionary innovations in the computational architectures made in 2015–2017 have led to dramatic improvements in the quality of machine translation (MT) and changed the field forever.

Historically, the relationship between human translation and MT has been uneasy and complicated, but an increasing number of players in both (...) fields are now coming to view it as synergistic. -/- OPUS-CAT is a collection of machine translation software based on a Windows implementation of Marian NMT—a stable production-ready neural machine translation framework used in many industrial and research applications.

Yuri Matiyasevich's theorem states that the set of all Diophantine equations which have a solution in non-negative integers is not recursive. Craig Smoryński's theorem states that the set of all Diophantine equations which have at most finitely many solutions in non-negative integers is not recursively enumerable. Let R be a subring of Q with or without 1. By H_{10}(R), we denote the problem of whether there exists an algorithm which for any given Diophantine equation with integer coefficients, can decide (...) whether or not the equation has a solution in R. We prove that a positive solution to H_{10}(R) implies that the set of all Diophantine equations with a finite number of solutions in R is recursively enumerable. We show the converse implication for every infinite set R \subseteq Q such that there exist computable functions \tau_1,\tau_2:N \to Z which satisfy (\forall n \in N \tau_2(n) \neq 0) \wedge ({\frac{\tau_1(n)}{\tau_2(n)}: n \in N}=R). This implication for R=N guarantees that Smoryński's theorem follows from Matiyasevich's theorem. Harvey Friedman conjectures that the set of all polynomials of several variables with integer coefficients that have a rational solution is not recursive. Harvey Friedman conjectures that the set of all polynomials of several variables with integer coefficients that have only finitely many rational solutions is not recursively enumerable. These conjectures are equivalent by our results for R=Q. (shrink)

In April 1961, Yuri Gagarin became the first human being to journey beyond Earth’s atmosphere and enter outer space. This achievement cemented the status of the Soviet Union as a global superpower and intensified its race with the United States to be the first nation to put a person on the Moon. However, what many people are far less aware of is that a proto-transhumanist and quasi-religious movement in the nineteenth century laid the philosophical foundations for the Space Race. (...) At the same time, the writings of its main proponents continue to inspire beliefs at the confluence of religion, space exploration and spirituality. This movement was called Cosmism and was spearheaded by an unusual character named Nikolai Fyodorov, a librarian from Moscow whose idiosyncrasies became just as notorious as his radical beliefs about humanity colonising the Milky Way and using science to resurrect the dead. Fyodorov’s Common Task set out a grand plan for humanity’s future, one in which Homo sapiens would become a spacefaring species and construct a utopian civilisation among the stars. In 1953, Israeli political theorist Mordechai Nessyahu founded Cosmodeism which advocated a similar endeavour of human expansion into the extraterrestrial world but focused its beliefs around the prophecy that spaceflight will see humans eventually become gods in a presently godless cosmos. However, new developments have begun to take place in space religion in the twenty-first century with the youngest religion having been founded only a decade ago in 2013 whose followers are known as Astronists. Astronism repackages human space expansion as a sacred endeavour called transcension, the object of which is to see humanity escape the cosmos entirely and thus relieve itself of all limitations. Studying the interplay between these three space religions will demonstrate how they have contributed to art and film, astronautics and spaceflight, philosophy and literature. (shrink)

When do objects at different times compose a further object? This is the question of diachronic composition. The universalist answers, ‘under any conditions whatsoever’. Others argue for restrictions on diachronic composition: composition occurs only when certain conditions are met. Recently, some philosophers have argued that restrictions on diachronic compositions are motivated by our best physical theories. In Persistence and Spacetime and elsewhere, Yuri Balashov argues that diachronic compositions are restricted in terms of causal connections between object stages. In a (...) recent article, Nikk Effingham argues that the standard objections to views that endorse restrictions on composition do not apply to a view that restricts composition according to compliance with the laws of nature. On the face of it, such restrictions on diachronic composition preserve our common-sense ontology while eliminating from it scientifically revisionary objects that travel faster than the speed of light. I argue that these attempts to restrict diachronic composition by appealing to either causal or nomological constraints face insurmountable difficulties within the context of special relativity. I discuss how the universalist should best respond to Hudson’s argument for superluminal objects, and in doing so, I present and defend a new sufficient condition for motion that does not entail that such objects are in superluminal motion. 1 Introduction2 Diachronic Composition3 Diachronic Composition and Superluminal Objects4 Restricting Diachronic Composition5 Causal and Nomological Restrictions on Composition in a Relativistic Context6 Superluminal Objects and Motion7 Conclusion.

I discuss the early history of holography and explore how perceptions, applications, and forecasts of the subject were shaped by prior experience. I focus on the work of Dennis Gabor (1900–1979) in England,Yury N. Denisyuk (1927-2005) in the Soviet Union, and Emmett N. Leith (1927–2005) and Juris Upatnieks (b. 1936) in the United States. I show that the evolution of holography was simultaneously promoted and constrained by its identification as an analog of photography, an association that influenced its assessment by (...) successive audiences of practitioners, entrepreneurs, and consumers. One consequence is that holography can be seen as an example of a modern technical subject that has been shaped by cultural influences more powerfully than generally appreciated. Conversely, the understanding of this new science and technology in terms of an older one helps to explain why the cultural effects of holography have been more muted than anticipated by forecasters between the 1960s and 1990s.

Dennis Gabor devised a new concept for optical imaging in 1947 that went by a variety of names over the following decade: holoscopy, wavefront reconstruction, interference microscopy, diffraction microscopy and Gaboroscopy. A well-connected and creative research engineer, Gabor worked actively to publicize and exploit his concept, but the scheme failed to capture the interest of many researchers. Gabor’s theory was repeatedly deemed unintuitive and baffling; the technique was appraised by his contemporaries to be of dubious practicality and, at best, constrained (...) to a narrow branch of science. By the late 1950s, Gabor’s subject had been assessed by its handful of practitioners to be a white elephant. Nevertheless, the concept was later rehabilitated by the research of Emmett Leith and Juris Upatnieks at the University of Michigan, and Yury Denisyuk at the Vavilov Institute in Leningrad. What had been judged a failure was recast as a success: evaluations of Gabor’s work were transformed during the 1960s, when it was represented as the foundation on which to construct the new and distinctly different subject of holography, a re-evaluation that gained the Nobel Prize for Physics for Gabor alone in 1971. This paper focuses on the difficulties experienced in constructing a meaningful subject, a practical application and a viable technical community from Gabor’s ideas during the decade 1947-1957.

RELAÇÃO E EFEITOS BIOQUÍMICO-NUTRICIONAIS SOBRE O RETARDO DA MATURIDADE SEXUAL EM BOVINOS -/- -/- Emanuel Isaque Cordeiro da Silva -/- Departamento de Agropecuária – IFPE Campus Belo Jardim -/- [email protected] ou [email protected] -/- WhatsApp: (82)98143-8399 -/- -/- 12. RETARDO DA MATURIDADE SEXUAL -/- -/- Nos animais em crescimento, as deficiências em qualquer dos nutrientes: proteína, energia, macro ou microminerais, vitaminas e aporte hídrico, geram inibição das sínteses de proteínas específicas como os fatores de crescimento. Neste tipo de situação, as taxas (...) de ganho de peso e o desenvolvimento dos diferentes segmentos do trato reprodutivo se alteram. Os animais atrasam a idade a que chegam à puberdade, atrasando a entrada na vida produtiva como animais aptos a se reproduzir. O quadro de atraso à puberdade ocasiona atraso na idade a que se apresenta o primeiro parto, fator responsável por grande parte das falhas na eficiência reprodutiva. Sem dúvida, aspectos nutricionais são os maiores limitantes no crescimento e na maturidade reprodutiva, sendo assim, esse trabalho têm como cunho a apresentação de alguns destes fatores: -/- 12.1 Relação Energia:Proteína -/- A maturidade sexual relaciona-se com um consumo adequado de energia e com a obtenção de um peso corporal adequado; o crescimento depende, em grande medida, da ingestão abundante de elementos energéticos. Uma ração deficiente em energia diminui a velocidade de crescimento, reduz a produção de leite, retarda a puberdade, reduz a fertilidade e diminui a resistência às doenças e ao parasitismo. -/- Uma das causas mais comuns da baixa fertilidade e do atraso da maturidade sexual nas vacas leiteiras é a falta de energia em relação às necessidades do animal ou um balanço de energia negativo; além disso, este atraso no início tardio da maturidade sexual diminui o tempo de vida durante o qual os animais têm uma reprodução ativa. -/- A falta de energia na ração pode ser causada por um consumo insuficiente de alimentos ou por uma baixa digestibilidade de seus componentes (dieta de baixa qualidade) e, por um teor elevado de umidade na dieta. O baixo consumo de energia é normalmente o resultado de restrições alimentares. Em qualquer uma das situações, a falta de energia impede o animal de expressar seu potencial genético de produção e o problema complica-se se, por sua vez, existe deficiência em proteínas, minerais e vitaminas. -/- Como referenciado anteriormente, a energia têm papel fundamental em todos os mecanismos fisiológicos do animal, seja para a reprodução, fornecimento de leite ou para produção de carne, uma vez que possui relação direta com as mitocôndrias celulares. A energia é considerada um tipo de gordura, e possui relação direta com o sistema reprodutivo da vaca. Para a produção de leite, uma vaca pode utilizar suas reservas de gordura e transformá-las em leite, isto é, a cada quilo de gordura corporal pode-se obter de 7 a 9 quilos de leite. O fornecimento de energia têm como fator a categoria animal, o sistema produtivo, a idade etc. logo, a administração de energia deve obedecer os parâmetros de 1,75 a 1,25 Mcal/kg do alimento fornecido, seja matéria seca, volumoso ou ração concentrada. Vale frisar novamente que os níveis de energia administrada devem ser altos (1,72 Mcal/kg) para as vacas no início da lactação e deve-se diminuir gradativamente conforme chega o final da lactação, chegando a 1,54 Mcal/kg ou menos. No caso de prevenção contra o retardamento dos animais à idade reprodutiva, os níveis de energia para as bezerras de 0-3 meses com ± 150 kg deve ser de 1,70 Mcal/kg de MS para mantença e de 1,06 Mcal para ganho de peso diário; para bezerras com idade entre 6-12 meses e um peso de ± 250 kg o nível de energia deve ser de 1,54 Mcal para mantença e de 0,97 para ganho; por fim, para bezerras chegando a categoria de novilhas (> 12 meses) o ideal é o fornecimento de 1,39 Mcal para mantença e de 0,81 Mcal para ganho. Os alimentos que mais fornecem energia são o sebo, a gordura protegida, o milho, etc. -/- O efeito da proteína da dieta na reprodução é complexo. Em geral, quantidades inadequadas de proteína na dieta reduzem a produção de leite e o desempenho reprodutivo (maturidade sexual). Deficiências de proteínas diminuem os níveis de proteínas de reserva ou de transporte no sangue, fígado e músculos o que predispõe o animal a várias doenças que podem levar a não manifestação da maturidade sexual ou mesmo a morte. -/- Há tipos de proteínas como a PB (proteína bruta), a PDR (proteína degradada no rúmen), proteína metabolizável entre outras, ambas possuem relação com a PB e são primordiais no entendimento da nutrição de ruminantes. Os níveis de PDR se forem baixos mostra uma boa população microbiana presente no rúmen do animal, esse compartimento que se desenvolve conforme a ingestão de alimentos concentrados. -/- Para que se possa prevenir o retardamento dos animais à maturidade sexual, deve-se estar atentos aos níveis de proteína que se administra aos animais, em especial para as bezerras que entrarão logo na puberdade estando aptas para se reproduzir. Contudo, o tipo e a quantidade de proteína se limita a fatores como os ingredientes da ração, método alimentar utilizado na propriedade e o potencial produtivo do lote que se maneja. Sendo assim, os níveis oscilam conforme a categoria, idade e peso como demonstra na tabela 1, que traz os níveis ideias de proteína que devem estar presentes na alimentação das bezerras conforme idade e peso médio das mesmas. -/- Tabela 1: Exigências de proteína em bezerras e novilha -/- Nutriente 3-6 meses (± 150 kg) 6-12 meses (± 250 kg) > 12 meses (± 400 kg) -/- PB % 16 12 12 -/- PDR % 8,2 4,3 2,1 -/- Fonte: TEIXEIRA, 1997. -/- Para que as bezerras entrem na maturidade sexual sem atraso ou quaisquer problema, é ideal que a ração que viera ser fornecida para as mesmas possuam uma quantidade básica de 22% de PB presente na composição. Os alimentos mais proteicos são os de origem animal como a farinha de sangue, de penas etc., porém sua administração deve ser limitada. Sendo assim, a tabela 2 traz os possíveis melhores alimentos a serem ofertados aos animais e sua quantidade diária para que se possa suprir os requerimentos dos animais e prevenir o retardamento sexual ou qualquer outro problema reprodutivo que tenha relação nutricional. -/- Tabela 2: Alimentos proteicos e quantidades ideais para bovinos -/- Alimento PB% Quantidade % da mistura ou kg/cab./dia -/- Caroço de algodão 21 ± 50% da mistura da ração (1 kg = 0,5 kg de caroço) -/- Farelo de glúten de milho 23 Pode substituir o volumoso (máximo 3,5 kg/cab./dia) -/- Grão de soja 38 ± 20% da mistura (1 kg = 0,2 kg de grão) ou no máximo 2,5-3,5 kg/cab./dia -/- Farelo de algodão 41 ± 30-40% da mistura (1 kg = 0,3-0,4 kg de farelo) ou no máximo 4,5 kg/cab./dia -/- Fonte: TEIXEIRA, 1997. -/- A Ureia e outras substâncias que contêm nitrogênio não proteico (NNP) podem ser utilizadas pelos microrganismos do rúmen para a produção de proteínas bacterinas. Em geral, a utilização da NNP não é recomendada, exceto em situações especiais de alimentação e sob controle técnico, uma vez que um manejo inadequado, nomeadamente de excessos de consumo, pode provocar intoxicações com efeitos letais (ROIG, 2003; FERGUSON et al., 1989). É claro que as fontes de NNP não possuem aminoácidos e que muitos deles são essenciais e não são sintetizados pela microbiota ruminal. -/- Alguns autores argumentam que o nitrogênio não proteico (NNP) como a ureia, pode ser muito bem utilizado desde que não exceda um terço do total de nitrogênio na dieta diária ou 3% da ração de grãos de cereais e após adaptação gradual de, pelo menos, três semanas. A boa utilização da ureia nos ruminantes depende da ração conter pelo menos 75% de nutrientes digestíveis totais NDT, disponibilidade suficiente de amido e de CNE para converter o nitrogênio da ureia em proteína microbiana e quando o teor de proteína verdadeira da ração não for inferior a 12% (ROIG, 2003). -/- 12.2 Minerais (K e I) -/- Um excesso de potássio no sangue ocorre quando o consumo excede a capacidade do rim de o eliminar, provocando um atraso na maturidade sexual, ciclos sexuais irregulares e baixa natalidade; também interfere na absorção intestinal do magnésio, dificultando a absorção e o metabolismo do cálcio, magnésio e sódio; geralmente afeta fêmeas de alta produção leiteira (com o leite é excretado muito magnésio). -/- No macho, o excesso de potássio diminui a fecundidade, altera as vesículas seminais e influencia a composição espermática. Na fêmea prejudicaria os ciclos sexuais (duração e intensidade). -/- A excreção de íons de potássio diminui quando se ingere pouca quantidade deste elemento e de sódio, e quando há acidose aguda ou insuficiência das glândulas adrenais. -/- O potássio é um elemento de muitas funções no metabolismo animal e participa de múltiplos mecanismos fisiológicos, dentre eles o reprodutivo.

Abstract: The present paper seeks to explore the emotional structures that make human beings afraid of death in solitude, the feelings that necessitate the imagining of a peopled death, a death accompanied by fellow humans, gods, or God. In order to do this I take up the works of two great thinkers of the East and the West, and place them on a comparativist spectrum. The discussion covers many areas, including the polytheistic imaginations of ancient Greece and eighth century India, (...) in the context of the complex interface of beauty and death in the thought of Shankaracharya, the great proponent of Advaita Vedanta in India, and Socrates, who, in the Platonic dialogues, presents a monism Shankara could have recognized well. I try to investigate the tension between decay and beauty which leads these philosophers towards a strict ascetic impulse. At the same time, I also argue that neither of them could exclude the beauty of this world altogether from their thought. Finally, I explore the ways in which we can imagine a beauty greater than death that does not let us logocentrically negate death but rather encompasses it. Rather than taking death as the closure of all possible beauty, as ultimate nothingness, can we envisage a beauty that drowns death in the sea of kalon envisioned by Diotima in the Symposium, or in the saundaryalahari, the flood of majestic beauty radiated by Shankaracharya’s Goddess? To explore these areas and to understand the interconnected issues of plurality, impermanence, beauty and truth, I draw on the twentieth century philosophers like Iris Murdoch and Sri Aurobindo as well as Socrates and Shankara. This paper finally embarks on an imaginative journey towards a peopled or crowded death, where gods or divinized humans accompany the dying person in the process of death as his/her “necessary others”(a la Adriana Cavarero).
