RESUMO A alimentação é o fator que mais onera um sistema de produção animal. Assim, a utilização de diferentes estratégias de alimentação dos animais ainda é o grande desafio da nutrição animal, principalmente, levando em consideração as exigências nutricionais de diferentes categorias de ruminantes, em especial bovinos em regiões tropicais, haja vista que a sazonalidade na produção de forragens afeta diretamente a produção bovina, promovendo inadequação no atendimento das exigências nutricionais dos animais principalmente em minerais e vitaminas. Uma alimentação que (...) não atenda as exigências nutricionais dos ruminantes gera prejuízos no sistema de produção, além de, em casos mais graves, ocasionar a perda do animal. Estudos que abordam o efeito e a importância de vitaminas e minerais na nutrição bovina são escassos e necessários. Recentemente a National Research Council (NRC) apresentou novos registros das exigências nutricionais das vitaminas e minerais. Essas alterações proporcionam um impacto econômico significativo em relação à nutrição animal. Nesse sentido, objetivou-se com esta revisão trazer informações acerca de vitaminas e minerais na nutrição de bovinos em pastejo. -/- Palavras-chave: Alimentação animal; forragem; pastagem; requerimentos nutricionais; ruminantes; vitaminas lipossolúveis (Source: AGROVOC). -/- ABSTRACT Animal feed is the factor that most burdens a production system. Thus, the use of different animal feeding strategies is still the great challenge of animal nutrition, taking into account the nutritional requirements of different categories of ruminants, especially cattle in tropical regions, given that seasonality in forage production directly affects cattle production, promoting inadequacy in meeting the nutritional requirements of animals, mainly in minerals and vitamins. A diet that does not meet the nutritional requirements of ruminants generates losses in the production system, in addition to, in more serious cases, causing the loss of the animal. Studies that address the effect and importance of vitamins and minerals in bovine nutrition are scarce and necessary. Recently the National Research Council (NRC) presented new records of the nutritional requirements of vitamins and minerals. These changes provide a significant economic impact on animal nutrition. In this sense, the objective of this review was to bring information about vitamins and minerals in the nutrition of grazing cattle. -/- Keywords: Animal feeding; fat soluble vitamins; forage; nutritional requirements; pasture feeding; ruminants (Source: AGROVOC). -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- 1.

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. Sendo assim, é importante o criador estar atento sobre a administração do mineral na alimentação das bezerras que vão entrar para a maturidade sexual.

In this paper, I argue that the fetishism objection to moral hedging fails. The objection rests on a reasons-responsiveness account of moral worth, according to which an action has moral worth only if the agent is responsive to moral reasons. However, by adopting a plausible theory of non-ideal moral reasons, one can endorse a reasons-responsiveness account of moral worth while maintaining that moral hedging is sometimes an appropriate response to moral uncertainty. Thus, the theory of moral worth upon which the (...) fetishism objection relies does not, in fact, support that objection. (shrink)

Morally speaking, what should one do when one is morally uncertain? Call this the Moral Uncertainty Question. In this paper, I argue that a non-ideal moral theory provides the best answer to the Moral Uncertainty Question. I begin by arguing for a strong ought-implies-can principle---morally ought implies agentially can---and use that principle to clarify the structure of a compelling non-ideal moral theory. I then describe the ways in which one's moral uncertainty affects one's moral prescriptions: moral uncertainty constrains the set (...) of moral prescriptions one is subject to, and at the same time generates new non-ideal moral reasons for action. I end by surveying the problems that plague alternative answers to the Moral Uncertainty Question, and show that my preferred answer avoids most of those problems. (shrink)

There are cases in which, intuitively, an agent’s action is both morally right in one sense, and morally wrong in another sense. Such cases (along with other intuitions about blameless wrongdoing and action-guidance) support distinguishing between the objective moral ‘ought’ and the subjective moral ‘ought.’ This chapter argues against drawing this distinction, on the grounds that the prescriptions delivered by an adequate objective moral theory must be sensitive to the mental states of agents. Specifically, an adequate theory of the objective (...) moral ‘ought’ must respect a strong ought-implies-can principle—morally ought implies agentially can—in order to prescribe actions to real-life agents. An agent’s mental states determine what is agentially possible for that agent; thus, what an agent objectively morally ought to do is in part determined by the agent’s mental states. This chapter describes the structure of a compelling non-ideal moral theory that is both objective and mental state-sensitive. This non-ideal theory illuminates the shortcomings of extant objectivist and subjectivist moral theories, and illustrates how we can dispense with the subjective moral ‘ought.’. (shrink)

This paper develops an endurantist theory of persistence. The theory is built around one basic tenet, which concerns existence at a time – the relation between an object and the times at which that object is present. According to this tenet, which I call transcendentism, for an object to exist at a time is for it to participate in events that are located at that time. I argue that transcendentism is a semantically grounded and metaphysically fruitful. It is semantically grounded, (...) insofar as a semantic analysis of our temporal talk favors it over rivals. It is metaphysically fruitful, insofar as the theory of persistence that can be built around it – the transcendentist theory of persistence, to give it a name – requires neither temporal parts nor the problematic commitments to which all extant forms of endurantism are committed, such as the possibility of extended simples or multilocation.

This paper considers three possible ways of understanding the claim that the American criminal justice system is racist: individualist, “patterns”-based, and ideology-based theories of institutional racism. It rejects an individualist explanation of institutional racism because such an explanation fails to explain the widespread prevalence of anti-black racism in this system or indeed in the United States. It considers a “patterns” account of institutional racism, where consistent patterns of disparate racial effect mimic the structure of intentional projects of racial subjugation like (...) slavery or Jim Crow. While a “patterns” account helpfully directs attention to the effects of policies and practices that make up an institution, it does not fully explain the deep roots of anti-blackness in the criminal justice system in the United States. The paper concludes by defending an ideology-based theory of institutional racism for understanding the criminal justice system because the stereotype of the black criminal has a mutually reinforcing relationship with the patterns of disparate outcome for black people in the criminal justice system. This relationship creates a looping effect where the stereotype of the black criminal fuels the disproportionate involvement of black people in the criminal justice system, and the disproportionate representation of black people with felony records, in prisons, brutalized in police encounters, and so on reinforces the idea that black people are especially prone to criminality. Ideological approaches to racism that integrate attention to the patterns of disparate effect best explain what it means to say that the criminal justice system is racist. (shrink)

Sean McKeever and Michael Ridge object that moral particularism ‘flattens the moral landscape’, that is, that particularism treats reasons of different kinds as if they were reasons of the same kind. This objection is misguided in two respects. First, particularists need not say that every feature can be a moral reason. Second, even if particularists were committed to saying that every feature can be a moral reason, they would still not be committed to the view that every feature can have (...) direct moral relevance. The failure of this objection shows that the objection exploits side-constraints that need not be placed on moral particularism. (shrink)

English interpretations, appropriations, and transpositions of the figure of Don Quixote play a pivotal role in eighteenth-century constructions of so-called English national character. A corpus of quixotic narratives worked to reinforce the centrality of Don Quixote and the practice of quixotism in the national literary landscape. They stressed the man from La Mancha’s eccentricity and melancholy in ways inextricable from English self-constructions of these traits.2 This is why Stuart Tave is able to write that eighteenth-century Britons could “recast” Don Quixote (...) in a fashion that followed “national pride” in the “freedom” of their humors.1 However, Don Quixote’s integral place in patriotic self-constructions was troubled by gender. While national character was construed as masculine by default, quixotism’s association with masculinity was complicated by the potential passive penetrability of quixotism and the proliferation of narratives about female quixotic readers. This essay will analyze these tensions. Henry Fielding’s Joseph Andrews (1742) and Laurence Sterne’s Tristram Shandy (1759–67) are key examples of quixotic texts that respond to the figure of the female quixote by interrogating the relationship between Englishness, masculinity, and quixotism.

The aim of this paper is to clarify the truth-functional interpretation of the logical connective of the material implication. The importance of such clarification lies in the fact that it allows avoiding the supposed paradoxes introduced by C. I. Lewis (1918). I argue that an adequate understanding of the history and purposes of logic is enough to dissolve them away. The defense is based on an exposition of propositional compositionalism. To compare, I also present Stalnaker’s (1968) alternative that seeks to (...) explain the implicit concept of conditionality of conditionals assertions. In order to reinforce my aim I expound the twelve different meanings of ‘implication’ stated by Corcoran (1993) in order to hold that a proper understanding of these meanings allows us to avoid ambiguities and confusions. Finally, I expect to show that despite the possible alternatives, compositionalism is still the best explanation for the truth-functionality account of logical connectives. (shrink)

The Divine Comedy is a poem of Dante Alighieri representing, allegorically, the journey of a soul towards God, in the framework of Dante’s metaphysics of the divine light. However, besides metaphysics, we can find in the poem several passages concerning the natural phenomena. Here we discuss some them, in order to investigate Dante’s knowledge of Physics and, in particular, of Optics.

The article traces the evolution and crystallization of Buber’s philosophy of dialogue. It focuses on his consideration of the epistemological and ontological issues attendant to the principium individuationis, the subject of his doctoral dissertation of 1904. Culminating with the publication of Ich und Du in 1923, this process was punctuated by life experiences that led him to affirm rather than to seek to transcend the principium individuationis as the ontological ground of being manifest in the matrix of everyday life, which (...) we are beckoned to sanctify through I-Thou relations.

Since 1900, debates about the justification of punishment have also been debates about the cause of crime. In the early twentieth century, the rehabilitative ideal of punishment viewed mental illness and dysfunction in individuals as the cause of crime. Starting in the 1970s, retributivism identified the immorality of human agents as the source of crime, which dovetailed well with the “tough-on-crime” political milieu of the 1980s and 1990s that produced mass incarceration. After surveying these historical trends, Wirts argues for a (...) social critical view that crime is best understood as a product of an unjust society, not faulty human beings. This view should take the lessons learned by the critiques of rehabilitation, however, and resist the tendency to reduce human beings to recipients of social services. (shrink)

In their article, “Immigrant legalization: A Dilemma Between Justice and The Rule of Law,” Sarah Song and Irene Bloemraad address rule of law objections to policies that would regularize the status of undocumented immigrants in the United States. On their view, justice requires that liberal democratic states (i.e., states that are committed to individual liberty and universal equality) provide pathways for undocumented immigrants to regularize their status. We do not disagree with Song and Bloemraad’s account: rule of law and regularization (...) policies are not inconsistent, and in fact regularization supports rule of law, when properly understood. Our view is that there needs to be a deeper investigation into the motivations of “rule of law” objections considered in Song and Bloemraad’s account. We argue that the real purpose of these objections is not necessarily to serve as an alternative to the justice-based claims of undocumented immigrants, but as a way to undermine them. On our account, these rule of law objections accomplish this undermining task through the mechanisms of dog whistling, discrediting and distorting, and ostracizing. (shrink)

Review di due libri essenziali per conoscere meglio Amedeo Avogadro e il suo impegno nella società civile del tempo.

This paper aims 1) to introduce the notion of theoretical story as a resource and source of constraint for the construction and assessment of models of phenomena; 2) to show the relevance of this notion for a better understanding of the role and nature of values in scientific activity. The reflection on the role of values and value judgments in scientific activity should be attentive, I will argue, to the distinction between models and the theoretical story that guides and constrains (...) their construction. The aim of scientific activity is to develop understanding of phenomena, and something that serves this aim and contributes to the development of understanding has a cognitive value. Cognitive values are the features that something that plays a role in scientific activity should have so that it can serve its aim. I will focus my attention on the features of the theoretical story and of the models. (shrink)

The Monster Objection has often been considered one of the main reasons to explore non-standard mereological views, such as hylomorphism. Still, it has been rarely discussed and then only in a cursory fashion. This paper fills this gap by offering the first thorough assessment of the objection. It argues that different metaphysical stances, such as presentism and three- and four-dimensionalism, provide different ways of undermining the objection.

It is sometimes said that simulation can serve as epistemic substitute for experimentation. Such a claim might be suggested by the fast-spreading use of computer simulation to investigate phenomena not accessible to experimentation (in astrophysics, ecology, economics, climatology, etc.). But what does that mean? The paper starts with a clarification of the terms of the issue and then focuses on two powerful arguments for the view that simulation and experimentation are ‘epistemically on a par’. One is based on the claim (...) that, in experimentation, no less than in simulation, it is not the system under study that is manipulated but a system that ‘stands-in’ for it. The other one highlights the pervasive use of models in experimentation. It will be argued that these arguments, as compelling as they might seem, are each based on a mistaken interpretation of experimentation and that, far from simulation and experimentation being epistemically on a par, they do not have the same epistemic function, do not produce the same kind of epistemic results.

The possibility of multi-location—of one entity having more than one exact location—is required by several metaphysical theories such as the immanentist theory of universals and three-dimensionalism about persistence. One of the most pressing challenges for multi-location theorists is that of making sense of exact location—in that extant definitions of exact location entail a principle called ‘functionality’, according to which nothing can have more than one exact location. Recently in a number of promising papers, Antony Eagle has proposed and defended a (...) definition of exact location in terms of weak location that does not entail functionality. This paper provides the first thorough assessment of Eagle’s proposal. In particular, we argue that it cannot account for the location of immanent universals, the multi-location of mereologically changing three-dimensional objects, the multi-location of mereologically complex objects, and that it makes extended simples impossible.

Experimental activity is traditionally identified with testing the empirical implications or numerical simulations of models against data. In critical reaction to the ‘tribunal view’ on experiments, this essay will show the constructive contribution of experimental activity to the processes of modeling and simulating. Based on the analysis of a case in fluid mechanics, it will focus specifically on two aspects. The first is the controversial specification of the conditions in which the data are to be obtained. The second is conceptual (...) clarification, with a redefinition of concepts central to the understanding of the phenomenon and the conditions of its occurrence. (shrink)

Raymond Carver's stories have received many labels: minimalism, K-mart fiction, low-rent tragedy, neo-realism. Paring language, plot, and characterization to the bone, Carver concentrates his stories on instances of judgment and choice. These climactic moments affect not only the characters, but also the reader, who is called to fill the gaps in the text. The gaps generally show the unrelatedness of the characters' responses to the situations in which they find themselves. Relying on formulae, concepts, and rules taken for granted as (...) common knowledge, Carver's characters make choices and judgments which reveal the displacement of their consciousness of themselves and of the world. In trying to fill the gaps, the reader finds himself/herself in the same stance of making judgments and choices, and of looking at his/her own displacement. This predicament is more poignantly conveyed in the early stories, collected in Will You Please Be Quiet, Please?, Furious Seasons, and What We Talk About When We Talk About Love, since Carver writes about people "on the other side of the tracks," that is, on the edges of the sites of power and decisions. Bartenders, wage workers, and salespeople, Carver's characters in these early stories see their lives always threatened by joblessness, bankruptcy, and homelessness. In the later stories, collected in Cathedral and Where I'm Calling From, Carver explores possibilities in conversation, storytelling, and rituals that celebrate the here and now of each occasion and allow the merging of voices and feelings that places the individual's consciousness in the world.

In this paper, we are proposing a study of the Vesica Piscis, a symbol of Sacred Geometry, starting from mathematics.

Este trabajo parte del análisis de Heidegger en “¿Para qué poetas?”, donde el autor interpreta la poesía de Hölderlin a partir de su elegía «Pan y vino», aquí expondremos algunas de sus explicaciones. También intentaremos entender la respuesta que da Hölderlin en la que asocia los poetas a los «sacerdotes del dios del vino». Para ello nos ayudaremos de las nociones que de Dioniso nos ofrecen tanto Nietzsche como Hölderlin, presentaremos semejanzas y diferencias de algunas de sus interpretaciones. Aparte de (...) eso, reflexionaremos sobre la visión del artista como un dios y la relación existente entre la poesía y la filosofía. Concluiremos con las reflexiones que Heidegger hace en su trabajo “Aclaraciones a la poesía de Hölderlin”, donde el autor sobrevalora el papel de la poesía, considerando incluso que los poetas pueden llegar a esclarecer pensamientos de cualquier filosofía pensada a medias.

Here we propose a discussion about the "mandorla" or "vesica piscis". It is a type of 2-dimensional lens, that is, a geometric shape formed by the intersection of two circles with the same radius, intersecting in such a way that the centre of each circle lies on the perimeter of the other. The aim of the discussion is that of understanding when such a geometric shape became a symbol and when this symbol received a specific name. We will find that (...) the name "mandorla" was used long before the term "vesica piscis", which is the Latin translation of the German "fischblosen" used by Albrecht Dürer in his book on geometry. Therefore, the name invented by Dürer was not used by the painter for a sacred form. However, after the middle of the nineteenth century the term "vesica piscis" exploded in literature. Its use was criticized and, at the same time, it was stressed that the proper term for the symbol is "mandorla". Nonetheless, the "vesica piscis" continues to be largely used in the sacred geometry, which ascribes symbolic and sacred meanings to certain geometric shapes and proportions. In the proposed discussion, we will also show that, recently, the 2-dimensional lenticular symbol has been related to the Pythagorean philosophy. It is told that the followers of this philosophy had the habit of using an apple for symbolic communications. Sliced across, the core of the apple is displaying a pentagram, but sliced lengthwise it forms two intersecting circles, that is a "mandorla". Then, the investigation about terms and related uses of this specific geometric shape is the core of the matter of our discussion or, let us tell, the "core of the apple", in a Pythagorean-like approach to find how a German "fischblosen" evolved into a sacred symbol, thanks to a translation into Latin.

in academic entrepreneurship and creation of university spin-off companies has grown in South Africa. This study aims to establish the factors that inspire academics to engage in entrepreneurial activities and to identify the role that academic entrepreneurs play in the process of technology transfer and commercialization at University of Technology (UoT) X. A quantitative research approach is adopted throughout this study. As part of the quantitative research approach, structured questionnaires were directly administered to the respondents to collect the data. Specifically, (...) 52 electronic survey questionnaires were distributed. The sample is drawn from two databases compiled, using UOTX’s internal research records. One of the databases, held a list of those academics who have been active in terms of research as evident in their research outputs – technology creation and transfer. The other database (control group) holds a list of those academics that have not been active. From both groups, a purposive sample is drawn for the survey questionnaire. This study notes that pull factors tend to influence the entrepreneurial activities of academics at UOT X more than push factors and that academics are key players in the process of technology transfer. Thus, this study may assist the university senior management to develop strategies to improve academic entrepreneurship for all faculties. In line with this, it is expected that the primary function of UOT X should be to instil a greater entrepreneurial spirit among the relevant stakeholders. (shrink)

Relativity theory is often said to support something called ‘the four-dimensional view of reality’. But there are at least three different views that sometimes go by this name. One is ‘spacetime unitism’, according to which there is a spacetime manifold, and if there are such things as points of space or instants of time, these are just spacetime regions of different sorts: thus space and time are not separate manifolds. A second is the B-theory of time, according to which the (...) past, present, and future are all equally real and there is nothing metaphysically special about the present. A third is perdurantism, according to which persisting material objects are made up of different temporal parts located at different times. We sketch routes from relativity to unitism and to the B-theory. We then discuss some routes to perdurantism, via the B-theory and via unitism. (shrink)

The Aristotelian view of universals, according to which each universal generically depends for its existence on its instantiations, has recently come under attack by a series of ground-theoretic arguments. The last such arguments, presented by Raven, promises to offer several significant improvements over its predecessors, such as avoiding commitment to the transitivity of ground and offering new reasons for the metaphysical priority of universals over their instantiations. In this paper, we argue that Raven's argument does not effectively avoid said commitment (...) and that Raven's new reasons fail. Moreover, we present a novel ground-theoretic interpretation of the Aristotelian view, referred to as strong immanence, and introduce a new argument against the Aristotelian view, intended to sidestep any commitment to the transitivity of ground.

Priority monism is the view that the cosmos is the basic concrete entity on which each of its parts depend. Kovacs has recently argued that none of the classical notions of dependence could be used to spell out priority monism. I argue that four notions of dependence – namely rigid existential dependence, generic existential dependence, explanatory dependence, and generalised explanatory dependence – can indeed be used to spell out priority monism, and specify the conditions under which this is possible.

Using research grants administrators and their clients (academic researchers) as the lens, this paper investigated the relevance and implication of a fraud prevention policy at a University of Technology (UoT) in South Africa. The paper adopted a quantitative approach in which closed-ended questions were complemented by open-ended questions in the survey questionnaire in the attempt to capture the perceptions of both research grants administrators and their clients on the relevance and implications of a fraud and irregularity prevention policy. The results (...) indicate that both research grants administrators (71.4 %), and their clients (73%) do not know if UoTx has a fraud and irregularity policy. While only 36% of research grants administrators indicated that they would feel safe reporting deceitful activities, a slight majority (59%) of the clients reported same. With regards to the steps to follow to report fraudulent activity, it was noted that while all (100%) the research grants administrators noted that they were clueless, ironically an overwhelming majority of their clients indicated otherwise. Notwithstanding, both research grants administrators and their clients (93% and 95% respectively) concurred that a fraud prevention policy was necessary for UoTx. The implication is that having phenomenal controls that are not effectively publicized, monitored or worse still overridden by someone are useless. (shrink)

How to be being to be being/ next to the united and firm/ and trembling/ mouth of the poem?”, “How to say what is clearer than clarity [...]?” or “How to unite a light design and an obscure gesture?” These questions, as well as many others that emerge from the poetic and essay writing of António Ramos Rosa (1924-2013), represent different modulations of the same angular question: that of the relation between poem and reality, or, more radically, between poem and (...) being. And if such a question spreads into so many formulations it is because, in António Ramos Rosa, its scope is total, simultaneously aesthetic and ontological, metaphysical and spiritual. It is, therefore, this question that we will try to answer by looking into one of its possible faces: how can poetic creation be at the same time the most intimate gesture and the one that touches most deeply the undomesticated matter of the real, that absolute and unapprehensible Other?

How do objects persist through time? According to endurantism, objects persist through time and do not have temporal parts. According to the transcendentist version of endurantism, objects exist at times by participating in events that occur at those times. This version of transcendentism offers specific metaphysical and semantical advantages over other versions of endurantism. In this paper, we defend transcendentist endurantism against a series of criticisms that have been recently offered by Kristie Miller.

Following a previous article (cf. Costa-Leite, A. (2018).

In the world of Philosophy for Children (P4C), the word “method” is found frequently in its literature and in its practitioner’s handbooks. This paper focuses on the idea of community of philosophical inquiry (CPI) as P4C’s methodological framework for educational purposes, and evaluates that framework and those purposes in light of the question, what does it mean to bring children and philosophy together, and what methodological framework, if any, is appropriate to that project? Our broader aim is to highlight a (...) problem with regards to the concept of method in P4C, and to question the consequences of that concept in the practice of philosophical dialogue with children. To better situate the concept of method within P4C (which, we think, will help to clarify some of the dialogues and debates within P4C as a philosophical field), we will identify two different historical understandings—represented by Rene Descartes and Hans Georg Gadamer—of the concept, and suggest new possibilities for understanding philosophical practice with children in light of their difference.

In the debate about Christian attitudes to other religions, a threefold typology has emerged depicting differing Christian responses: pluralism, inclusivism and exclusivism. (This typology is not restricted to the Christian debate alone.) Traditionally, pluralism is opposed to exclusivism, the former claiming that it is arrogant and untenable to make exclusive truth claims, and that all religions are potentially equal paths to salvation and truth. In contrast, I argue that pluralism must always logically be a form of exclusivism and that nothing (...) called pluralism really exists. The main purpose of my paper is to show that there is no high-ground in the pluralist position, for in principle its logic is no different from the exclusivist position. If this is established, then the debate can proceed with more substantial issues regarding the justification and clarification of truth claims. (shrink)

In this paper, I seek to examine Deleuze’s fascination with “spiritual automata” as a counterpoint to his more famous notion, the “body without organs”. I shall argue that both are grounded in a deep reflection, on Deleuze’s part, on the problems and issues generated by Spinoza’s notion of parallel attributes. Ultimately, I argue, the development of the two notions is motivated by identical metaphysical worries regarding the tenability of transformation, persistence, and affective interrelations between individuals. The answer, for both thinkers, (...) is the insertion of a “third” relational term, which virtually interfaces with each without violation of their parallel development. For Spinoza, such term is the absolutely infinite substance; for Deleuze, it is instead the notion of sense and the faculty of sense-making. (shrink)

I defend my paper “Aquinas, Geach, and Existence”[1]against objections from Luca Gili, who argued that, according to Aquinas, future contingents do not enjoy genuine existence but exist in God’s mind only.[1] Damiano Costa, “Aquinas, Geach, and existence”, European Journal for Philosophy of Religion 11, no. 3.
