An influential heuristic for thinking about climate adaptation asserts that “natural” adaptation strategies are the best ones. This heuristic has been roundly criticized but is difficult to dislodge in the absence of an alternative. We introduce a new heuristic that assesses adaptation strategies by looking at their maturity, power, and commitment. Maturity is the extent to which we understand an adaptation strategy’s effects. Power is the size of the effect an adaptation strategy will have. Commitment is the degree to which (...) an adaptation strategy is difficult to test or reverse. (shrink)

Nature-based solutions (NbS) have in recent years occupied a central position in conservation and climate discussions among both scientists and policy makers. NbS generally refer to a set of strategies which use nature, or natural objects, to address societal (human) issues while simultaneously supporting the broader environment. This paper examines the concept of NbS to determine whether it is a useful and well-motivated category to guide future climate and conservation efforts. I argue that NbS may in fact be a valuable (...) contribution to environmental thought and policy, but not for the reasons that they are typically thought to be. Specifically: while we have reason to doubt that NbS should be prioritized over other environmental strategies on the grounds that they are uniquely environmentally-friendly or supportive of biodiversity, they may nevertheless have an advantage insofar as they play a vital aesthetic role in developing a healthier relationship between humans and the nonhuman world.

Post-Traumatic Stress Disorder is a mental health condition in which the experience of a traumatic event causes a series of psychiatric and behavioral symptoms such as hypervigilance, insomnia, irritability, aggression, constricted affect, and self-destructive behavior. This paper investigates two case studies to argue that the experience of PTSD is not restricted to humans alone; we have good epistemic reason to hold that some animals can experience genuine PTSD, given our current and best clinical understanding of the disorder in humans. I (...) will use this evidence to argue for two claims. First, because the causal structure of PTSD plausibly requires reference to a traumatic conscious experience in order to explain subsequent behaviors, the fact that animals can have PTSD provides new evidence for animal consciousness. Second, the discovery of PTSD in animals puts pressure on accounts which hold that animal behavior can be fully explained without reference to subjective experience. (shrink)

Any philosophy of science ought to have something to say about the nature of mathematics, especially an account like constructive empiricism in which mathematical concepts like model and isomorphism play a central role. This thesis is a contribution to the larger project of formulating a constructive empiricist account of mathematics. The philosophy of mathematics developed is fictionalist, with an anti-realist metaphysics. In the thesis, van Fraassen's constructive empiricism is defended and various accounts of mathematics are considered and rejected. Constructive empiricism (...) cannot be realist about abstract objects; it must reject even the realism advocated by otherwise ontologically restrained and epistemologically empiricist indispensability theorists. Indispensability arguments rely on the kind of inference to the best explanation the rejection of which is definitive of constructive empiricism. On the other hand, formalist and logicist anti-realist positions are also shown to be untenable. It is argued that a constructive empiricist philosophy of mathematics must be fictionalist. Borrowing and developing elements from both Philip Kitcher's constructive naturalism and Kendall Walton's theory of fiction, the account of mathematics advanced treats mathematics as a collection of stories told about an ideal agent and mathematical objects as fictions. The account explains what true portions of mathematics are about and why mathematics is useful, even while it is a story about an ideal agent operating in an ideal world; it connects theory and practice in mathematics with human experience of the phenomenal world. At the same time, the make-believe and game-playing aspects of the theory show how we can make sense of mathematics as fiction, as stories, without either undermining that explanation or being forced to accept abstract mathematical objects into our ontology. All of this occurs within the framework that constructive empiricism itself provides the epistemological limitations it mandates, the semantic view of theories, and an emphasis on the pragmatic dimension of our theories, our explanations, and of our relation to the language we use.

Born to secular Jewish parents and raised in Camden, New Jersey, Andrea Dworkin became a radical second-wave feminist. By Dworkin’s own account, her work is informed by a series of negative personal experiences, including sexual assault at age nine, again by doctors at the Women's House of Detention in New York in 1965, work as a prostitute, and marriage to a battering husband whom she left in 1971. While Dworkin self-identified as a lesbian, since 1974 she lived with a gay (...) male partner, writer John Stoltenberg, whom she married in 1998. Understandably, the main theme of Dworkin's work is male violence against women. This violence is a defining feature of our male-supremacist culture, in which rape, prostitution, and pornography are inevitable expressions of gender norms. Dworkin's writings are primarily aimed at social change rather than intellectualizing. She describes her first book as "a political action where revolution is the goal". What one finds in her writings is not so much philosophical theorizing as calls to action. Thus it is difficult to summarize the abstract theory to which she is committed and from which she draws arguments against the sexism she finds in our culture. What is clear is her desire to eliminate binary concepts of gender and their oppressive effects. In particular, Dworkin urges the destruction of a female gender role that involves masochism, self-hatred, and passivity. She sees male supremacy constructed and reinforced in our culture through the sexist structuring of public institutions and private interactions, locating three crucial foci of male supremacy in action: pornography, sexual intercourse, and rape. These are her central concerns. Her work includes seven monographs, three collections of essays and speeches, a memoir, two novels, and a book of short stories, all of which explore these themes.

Although both EU policy makers and researchers acknowledge that public or stakeholder engagement is important for responsible innovation (RI), empirical evidence in this field is still scarce. In this article, we explore to what extent companies with a disposition to innovate in a more responsible way are moving towards the ideal of mutual responsiveness among stakeholders, as it is presented in the RI literature. Based on interviews with companies and non-economic stakeholders in the Dutch Food industry, it can be concluded (...) that innovative food companies are still far from implementing the ideal of mutual responsiveness in a significant way. The tension between the call for the active involvement of stakeholders in the literature and actual stakeholder engagement practices is explained by identifying a number of critical issues regarding stakeholder engagement, which are specific to actors involved in RI in the private sector. Finally, management practices designed to deal with these critical issues regarding stakeholder engagement are identified. (shrink)

The paper aims to explore what it means for something to be a social cycle, for a theory to be a social cycle theory, and to offer a suggestion for a simple, yet, we believe, fundamentally grounded schema for categorizing them. We show that a broad range of cycle theories can be described within the concept of disruption and adjustments. Further, many important cycle theories are true endogenous social cycle theories in which the theory provides a reason why the cycle (...) should recur. We find that many social cycle theories fit with a two-population disruption and adjustment model similar to the well-known predator-prey model. This implies that a general modeling framework could be established for creating agent-based models of many social cycle theories. (shrink)

Donald Hoffman proposed a bold theory—that objects do not exist independently of us perceiving them and that all that really exists is conscious agents. In this critical review, Leslie Allan examines the three core components of Hoffman's new idealism. He proposes solutions to linguistic absurdities suffered by Hoffman's theory before considering its most serious problems. These include oversimplifications of evolutionary theory, self-refutation, heuristic sterility and dependence on scientific realism.

An important objection to signaling approaches to representation is that, if signaling behavior is driven by the maximization of usefulness, then signals will typically carry much more information about agent-dependent usefulness than about objective features of the world. This sort of considerations are sometimes taken to provide support for an anti-realist stance on representation itself. The author examines the game-theoretic version of this skeptical line of argument developed by Donald Hoffman and his colleagues. It is shown that their argument (...) only works under an extremely impoverished picture of the informational connections that hold between agent and world. In particular, it only works for cue-driven agents, in Kim Sterelny’s sense. In cases in which the agents’ understanding of what is useful results from combining pieces of information that reach them in different ways, and that complement one another, maximizing usefulness involves construing first a picture of agent-independent, objective matters of fact.

In this review essay, K. Peter Kuchinke uses three recent publications to consider the question of how to educate young people for work and career. Historically, this question has been central to vocational education, and it is receiving renewed attention in the context of concerns over the ability of schools to provide adequate preparation for occupational roles and career success in a rapidly changing economic landscape. Philip Gonon's Quest for Modern Vocational Education provides a historical account of Georg Kerschensteiner's vision (...) of the role of work as a central subject matter for all students. His approach served as the foundation for the dual system in present‐day Germany. Nancy Hoffman's Schooling in the Workplace contrasts the U.S. system of career preparation for non‐college‐bound students with that of five other OECD nations where workforce and academic preparation are more strongly connected to learning in the workplace. Christopher Winch's Dimensions of Expertise, finally, offers a conceptual analysis of central ideas of vocational knowledge and underscores the important role of learning in the context of practice. The three texts offer historical, comparative, and philosophical analyses of the complex task of preparation for work and challenge education scholars to move the subject matter into the center of contemporary educational theory.

Preface: The following article is an adaptation of an open letter sent by the au- thor to the local U.S. Elementary School Administration on October 14, 2022, in response to the introduction of Transgender Literature in grades 2 and above (starting age 7) in the local US elementary school attended by the author’s children. More specifically, children have been introduced to three books: I Am Jazz, by Jessica Herthel and Jazz Jennings; Jacob’s New Dress, by Ian Hoffman and Sarah (...) Hoffman; and Born Ready. The True Story of a Boy Named Penelope, by Jodie Patterson. As part of this, children have been asked to join discussion in class to talk about the contents of each book and other related literature. Of note, several meetings with the administration and the school board have followed, but no changes have been made to the administration and content of the literature presented to children, with the exception of parents’ voluntary exclusion, per direct request, of their children from class time in which the books above and related new literature will be discussed in the future. Furthermore, these topics have also been discussed as part of a recent Lecture the author presented at the Academy of Sciences of Rome with the title “Science or Ideology?” in November 2022.

Kants Musikästhetik wird weithin unterschätzt. Dabei bietet sie die entscheidenden Ansätze zur Befreiung der Musik aus den Fängen der Nachahmungsästhetik, wie sie vor allem E.T.A.Hoffman kongenial umgesetzt hat.

This essay explains Donald Hoffman's Interface Theory of Perception using The Biological Framework for a Mathematical Universe proposed by Ronald Williams. According to Hoffman, what we perceive is more like a “desktop interface with icons representing complex underlying processes, rather than a direct window into the true nature of the world." The theory of a biological framework for a mathematical universes suggests that these complex underlying processes of “the desktop interface with icons” contain correspondences to biological systems. For (...) example, “the desktop icons” of the ocean’s arctic currents and the melting and freezing of Antartica contain “complex underlying processes” which mirror the processes of a circulatory system and beating heart. While indeed we do interpret reality from a superficial perspective as Hoffman suggests, our cognitive abilities are enhanced enough to recognize correspondences to these patterns pertaining to these biological systems which reveal the true nature of the world/universe/reality and thus highlight our evolved perceptual systems which can enable us how to recognize these patterns and organize ourselves to them in order to best survive it. Another example of a “desktop icon” is human society—the order and properties of human society contain “complex underlying processes” that are analogous to the order and properties of cellular society—thus “socioeconomic problems” can be understood through cellular economic problems. Moreover, the solution to the cellular economic problem is the solution to the socioeconomic problem. (shrink)

Susan Neiman pointed out to this reviewer the danger that Carl Jung studies pose to contemporary scholars. It is keeping in mind Neiman's cautionary advice that this review establishes Jung's contributions to Romanticism. "[Craig] Stephenson’s analysis of Aurélia has now superseded Arthur Lovejoy’s (1873–1962) and Mario Praz’s (1896–1982) contributions to the definitions of Romanticism.".

Since the stone age humankind has created masterworks which possess a mysterious quality of solidity and grandeur or monumentality. A Paleolithic Venus and a still life by Cezanne both share this monumentality. Michelangelo likened monumentality to sculptural relief, Braque called monumentality 'space', and Hans Hoffman, himself one of the masters, called monumentality 'pictorial depth.' The masters agreed on the import of monumentality, but none of them left a clear explanation of it. In 1943 Earl Loran published his classic book (...) on Cezanne's pictorial structure but, as I demonstrate, his explanation was misleading. This book provide a clear explanation, as did an earlier book by Robert Casper. This book also traces some history of monumentality with reproductions. It also explains how some painters achieved monumentality and how a student can attempt it. Pictorial space is created in the tension between pairs of opposing planes. Opposing planes pull against each other, each containing the other, paradoxically, within the flat surface of the canvas. Sculpture also can be 'plastic': opposing masses pull against each other, each containing the other and creating tension in the space which lies between them. Painting has other aspects like subject matter, expression, style and technique but pictorial space does not depend on these. Monumentality moves us profoundly and apparently has done so since the Paleolith. Using patients' vignettes, I show that there are profound parallels between the structure of a monumental work of art and the structure of an evolving personality. In Winnicott's words, such a personality has 'depth ... an interior space to put beliefs in ... an inside ... a space where things can be held ... the capacity to accept paradox [to contain opposites] ... room and strength ... and originality and the acceptance of tradition as the basis for invention'. A monumental painting also meets this description. I argue that monumental art provides a visual portrait of an evolving personality just as myth, as Freud and Jung both showed, provides a narrative portrait of an evolving personality. An evolving personality is perhaps humankind's most important creation; an underlying purpose of both myth and art is to help us achieve it. I demonstrate in this book that monumental art represented the evolving personality since at least 35,000 BC. Thus to understand monumentality is to better understand the personality and its history.

Kit Fine famously objected against the idea that essence can be successfully analyzed in terms of de re necessity. In response, I want to explore a novel, interesting, but controversial modal account of essence in terms of intrinsicality and grounding. In the first section, I will single out two theoretical requirements that any essentialist theory should meet—the essentialist desideratum and the essentialist challenge—in order to clarify Fine’s objections. In the second section, I will assess Denby’s improved modal account, which appeals (...) to the notion of intrinsicality, and argue that it is untenable. In the third section, I will explain how, when combined with a modal-existential criterion, a hyperintensional account of intrinsicality—in the same vein as Bader (J Philos 110(10): 525–563, 2013) and Rosen (in: Hale and Hoffman (eds) Modality: Metaphysics, logic, and epistemology, Oxford, OUP, 2010)—can help successfully address Fine’s counterexamples. In the fourth section, I will evaluate how this novel analysis of essence stands with respect to sortal, origin, and natural kinds essentialism and discuss potential objections and difficulties.

Commentators such as Kemp Smith (1941), Mendelbaum (1974), and Bricke (1980) have taken the distinctions of reason to pose either a counterexample to or a limitation of scope on the Separability Principle. This has been convincingly addressed by various accounts such as Garrett (1997), Hoffman (2011), and Baxter (2011). However, I argue in this paper that there are two notions of ‘distinction of reason’, one between particular instantiations (token distinctions of reason) and one between general ideas (type distinctions of (...) reason). Discussion of the distinctions of reason in the secondary literature has without fail focused on token distinctions of reason, but I will argue that type distinctions of reason prove problematic for Hume’s Separability Principle. I find a way around this problem that is consonant with Hume’s account of general ideas, but which can hardly be said to be an account which he explicitly or even implicitly endorsed. (shrink)

An inverse akratic act is one who believes X, all things considered, is the correct act, and yet performs ~X, where ~X is the correct act. A famous example of such a person is Huck Finn. He believes that he is wrong in helping Jim, and yet continues to do so. In this paper I investigate Huck’s nature to see why he performs such acts contrary to his beliefs. In doing so, I explore the nature of empathy and show how (...) powerful Huck’s empathic feelings are. Drawing from Martin L. Hoffman, I show the relationship between empathy and a principle of justice. This relationship leads to Huck acting virtuously, as Rosalind Hursthouse maintains. (shrink)

Phenomenal qualities are embodied spaciotemporal abstractions subjectively perceived by a conscious observer. Specific examples, i.e., qualia, include the color purple, the taste of chocolate, and the fragrance of a rose. The question of whether phenomenal awareness can be empirically understood forms one important facet of the “Hard Problem of Consciousness” (Chalmers, 1995, pp. 200–219). It is the position of this analysis that we will never understand why we experience sensory qualities in the manner we do until we first comprehend how (...) they may have evolved in the very distant past. This examination explores the evolutionary development of phenomenal experience. In so doing, it proposes that behind the mechanisms through which external stimuli interface with our sensory apparatus, there lies a long evolutionary process of standardization, approximation, and synchronization that has ultimately forged the close links between the two. The consistent and efficient correlations that the resultant evolutionary links give rise to cumulatively generate conscious experience. There is a tight correspondence between our sensations and incoming stimuli, and this synchronous covariance is meaningful and functional; however, it does not result from a strict cause-and-effect relationship between the physical properties of external objects and our internal neurophysiology. As such, this investigation endorses Hoffman’s (1998, 2003, 2008, 2009) view that the external world is largely hidden from direct sensory evaluation. The following inquiry utilizes Jung’s (1952) “Acausal Connecting Principle” to further explore the concept of complementary sensory phenomena as it may have originally been envisioned by Wolfgang Pauli. (Meier, 2001) This thesis, with respect to meaningful acausality and synchronicity, is first used to provide a plausible explanation for the initial genetic development of color perception, and then employed to examine the analogous evolutionary ties that ultimately engender all sensory modalities. Without invoking the Quantum-Mind hypothesis, this paper supports the idea that our five senses are not direct, or true, or even approximate abstract representations of any underlying material properties of incoming stimuli; instead, they efficiently provide useful higher-order assumptions pertaining to the macro properties of spacetime, matter, and motion, as well as the causal-objective of all life. The overall investigation concludes that it is the structural categorization, hierarchical organization, and qualitative characterization of this indirect presumptive meta-information that has engendered meaningful sensory experience, and all conscious thought over evolutionary time.

A popular positivistic line of thinking seems to be cropping up again, declaring that the sciences are on the verge of a paradigmatic shift. One that will merge science and philosophy to finally answer all the great big questions once and for all. Questions such as What is life? What is consciousness? What makes individuals who they are? Why does our universe seem fine-tuned for our existence? How did it all begin? While such questions are undoubtedly important, the truth is, (...) they are essentially philosophical. That is to say, they escape the kind of exactness required of the hard sciences. The upshot is that they are at best only answerable to a limited extent, if they are even answerable at all. (shrink)

Equality and identity. Bulletin of Symbolic Logic. 19 (2013) 255-6. (Coauthor: Anthony Ramnauth) Also see https://www.academia.edu/s/a6bf02aaab This article uses ‘equals’ [‘is equal to’] and ‘is’ [‘is identical to’, ‘is one and the same as’] as they are used in ordinary exact English. In a logically perfect language the oxymoron ‘the numbers 3 and 2+1 are the same number’ could not be said. Likewise, ‘the number 3 and the number 2+1 are one number’ is just as bad from a logical point (...) of view. In normal English these two sentences are idiomatically taken to express the true proposition that ‘the number 3 is the number 2+1’. Another idiomatic convention that interferes with clarity about equality and identity occurs in discussion of numbers: it is usual to write ‘3 equals 2+1’ when “3 is 2+1” is meant. When ‘3 equals 2+1’ is written there is a suggestion that 3 is not exactly the same number as 2+1 but that they merely have the same value. This becomes clear when we say that two of the sides of a triangle are equal if the two angles they subtend are equal or have the same measure. -/- Acknowledgements: Robert Barnes, Mark Brown, Jack Foran, Ivor Grattan-Guinness, Forest Hansen, David Hitchcock, Spaulding Hoffman, Calvin Jongsma, Justin Legault, Joaquin Miller, Tania Miller, and Wyman Park. -/- ► JOHN CORCORAN AND ANTHONY RAMNAUTH, Equality and identity. Philosophy, University at Buffalo, Buffalo, NY 14260-4150, USA E-mail: [email protected] The two halves of one line are equal but not identical [one and the same]. Otherwise the line would have only one half! Every line equals infinitely many other lines, but no line is [identical to] any other line—taking ‘identical’ strictly here and below. Knowing that two lines equaling a third are equal is useful; the condition “two lines equaling a third” often holds. In fact any two sides of an equilateral triangle is equal to the remaining side! But could knowing that two lines being [identical to] a third are identical be useful? The antecedent condition “two things identical to a third” never holds, nor does the consequent condition “two things being identical”. If two things were identical to a third, they would be the third and thus not be two things but only one. The plural predicate ‘are equal’ as in ‘All diameters of a given circle are equal’ is useful and natural. ‘Are identical’ as in ‘All centers of a given circle are identical’ is awkward or worse; it suggests that a circle has multiple centers. Substituting equals for equals [replacing one of two equals by the other] makes sense. Substituting identicals for identicals is empty—a thing is identical only to itself; substituting one thing for itself leaves that thing alone, does nothing. There are as many types of equality as magnitudes: angles, lines, planes, solids, times, etc. Each admits unit magnitudes. And each such equality analyzes as identity of magnitude: two lines are equal [in length] if the one’s length is identical to the other’s. Tarski [1] hardly mentioned equality-identity distinctions (pp. 54-63). His discussion begins: -/- Among the logical concepts […], the concept of IDENTITY or EQUALITY […] has the greatest importance. -/- Not until page 62 is there an equality-identity distinction. His only “notion of equality”, if such it is, is geometrical congruence—having the same size and shape—an equivalence relation not admitting any unit. Does anyone but Tarski ever say ‘this triangle is equal to that’ to mean that the first is congruent to that? What would motivate him to say such a thing? This lecture treats the history and philosophy of equality-identity distinctions. [1] ALFRED TARSKI, Introduction to Logic, Dover, New York, 1995. [This is expanded from the printed abstract.] .

REPRODUÇÃO EM NOVILHAS LEITEIRAS -/- INTRODUÇÃO -/- O principal objetivo da criação de substitutos em gado leiteiro é produzir uma novilha que tenha seu parto aos dois anos de idade (23 a 25 meses) e com um peso de 550 a 580 kg. O manejo reprodutivo das novilhas começa quando estas atingem 14 ou 15 meses de idade e um peso de 350 a 370 kg. A produção de novilhas deve ser suficiente para substituir as vacas descartadas anualmente (25 a (...) 35%), e para contribuir com o crescimento do rebanho. Espera-se que em um gado leiteiro deva haver uma população de animais de reposição, desde um dia de vida até à fase de novilha ao parto, correspondendo pelo menos a 70 % do total das vacas (figura 1). -/- Figura 1: A meta do programa de produção de substitutos ou fêmeas de reposição consiste em uma novilha que chegue ao seu primeiro parto aos 24 ou 25 meses de idade, entre um peso de 550 a 580 kg. Elaborado pelo autor. -/- A produção de novilhas depende basicamente de três fatores: da fertilidade das vacas, ou seja, do número de bezerras nascidas anualmente; da mortalidade durante a criação e desenvolvimento; e da eficiência reprodutiva das novilhas. O manejo reprodutivo moderno das novilhas é orientado para a utilização da inseminação artificial, seja em um estro natural ou sincronizado. As novilhas representam a população animal geneticamente mais avançada no rebanho, portanto, o mérito genético de suas crias obtidas por inseminação é maior do que o das crias das vacas adultas. Além disso, as crias das novilhas obtidas mediante a inseminação aceleram o avanço genético, uma vez que contribuem com uma proporção maior de substituições do rebanho em comparação com as crias das vacas de outras faixas etárias. Além disso, as novilhas são as fêmeas mais férteis do rebanho (porcentagem de concepção: 60 a 70% vs 30 a 40% em vacas), pelo que o custo do sêmen por gestação é menor em comparação com as vacas adultas, o que permite investir em melhores touros e em sêmen sexado. -/- 1. PUBERDADE -/- A puberdade é definida como a fase de desenvolvimento em que a fêmea apresenta o seu primeiro estro fértil. Regularmente as novilhas leiteiras, sob condições ótimas de manejo, chegam à puberdade entre 11 e 12 meses de idade, ou seja, antes de alavancar o peso recomendado para receber o primeiro serviço. Vale salientar que as novilhas podem ficar gestantes após a puberdade; no entanto, isto não é conveniente porque ainda não completou-se o seu desenvolvimento. Se ficarem gestantes nos primeiros ciclos estrais, as novilhas poderiam chegar ao parto com pouco desenvolvimento físico, o que provocaria distocias e baixa produção de leite (figura 2). A ativação do sistema neuroendócrino para que a bezerra atinja a puberdade é regulada principalmente pelo estado nutricional (condição corporal). A transição do anestro pré-puberal à ciclicidade puberal coincide com um aumento da condição corporal e das concentrações de insulina, IGF-I e leptina. Estes hormônios agem como sinais metabólicos no hipotálamo e hipófise que modificam a frequência de secreção das gonadotropinas, resultando na maturação folicular e ovulação. O atraso em relação à puberdade está diretamente relacionado com deficiências na alimentação; esta condição verifica-se em criações pouco tecnificadas, principalmente de pequenos e médios produtores. As novilhas que já atingiram o peso para receber o primeiro serviço e não apresentaram estro, devem ser examinadas por via retal para excluir possíveis anormalidades do desenvolvimento, tais como freemartinismo ou hipoplasia genital. -/- Figura 2: O fator mais importante que determina a puberdade é a nutrição. Bezerras bem alimentadas apresentam ciclos estrais aos 11 meses de idade e devem ser inseminadas aos 14 ou 15 meses de idade, com um peso de 350 a 370 kg. Acervo pessoal do autor. -/- 2. DETECÇÃO DE ESTRO E INSEMINAÇÃO ARTIFICIAL -/- A baixa eficiência na detecção de estros é o problema que mais afeta a eficiência reprodutiva das novilhas. De acordo com a duração do estro (8 a 18 horas), a observação das novilhas em períodos de 30 minutos durante a manhã e à tarde, permite detectar em estro até 70% das fêmeas, enquanto a observação contínua (24 horas) aumenta a eficiência na detecção até 95% (figuras 3 e 4). No manejo tradicional dos rebanhos leiteiros, as novilhas recebem pouca atenção por parte dos trabalhadores, o que resulta em baixa eficiência na detecção de estros (50 a 60%). Em diferença das vacas adultas em lactação, as novilhas estão menos expostas a fatores que diminuem a expressão do estro, portanto, com uma rotina de observação, de pelo menos duas horas na manhã (6h a 8h da manhã) e duas horas pela tarde até a noite (17h da tarde a 19h da noite), pode-se detectar até 90% das fêmeas no estro (figura 5). -/- Figura 3: O fator que mais influencia a idade ao primeiro parto é a baixa eficiência na detecção de estros, pelo que é recomendável a observação de estros com pessoal qualificado, em períodos de pelo menos duas horas pela manhã e duas à tarde. Acervo pessoal do autor. -/- Figura 4: Com a observação contínua é possível alcançar de 90 a 95% de eficiência na detecção de estros. Acervo pessoal do autor. -/- Figura 5: A inseminação deve ser realizada durante o período de receptividade sexual. Com boa eficiência na detecção de estros, a inseminação pode ser praticada no programa AM-PM e PM-AM, ou em apenas um turno de inseminação pela manhã (10:00), com bons resultados. -/- 3. TAXA DE PRENHEZ -/- O melhor indicador de eficiência reprodutiva é a taxa de prenhez. Este indicador refere-se à proporção de animais gestantes do total elegível para inseminação, num período equivalente a um ciclo estral. Como já se descreveu no trabalho Fisiologia do Estro e do Serviço na Reprodução Bovina, este indicador considera a eficiência na detecção de estros e a porcentagem de concepção, e reflete com maior objetividade a eficácia do manejo reprodutivo. Este parâmetro pode ser melhorado através de um aumento da proporção de novilhas detectadas em estro, o que se obtém aumentando o tempo de observação e aplicando técnicas de sincronização do estro (figura 6). -/- 4. INSEMINAÇÃO DE NOVILHAS COM SÊMEN SEXADO -/- A utilização de sêmen sexado é uma boa opção para a produção de novilhas de reposição. Com a nova tecnologia disponível para a separação de espermatozoides com o cromossomo x, é possível alcançar até 90% de crias fêmeas; no entanto, o processo de separação de espermatozoides tem baixa eficiência, o que limita o número de espermatozoides por palheta. As palhetas de inseminação com sêmen sexado contém de dois a três milhões de espermatozoides (doses de sêmen não sexado têm de 20 a 30 milhões). De acordo com os dados de fertilidade de gados comerciais, as novilhas inseminadas com sêmen sexado mostram de 10 a 20% menor concepção que novilhas inseminadas com sêmen não sexado, o que desencoraja o seu uso. Causas de baixa fertilidade não são conhecidas, no entanto, estão associadas com a menor concentração espermática e com alguns danos nos espermatozoides provocados pelo processo de separação. No entanto, o uso de sêmen sexado é uma opção viável para aumentar a produção de novilhas no rebanho, e com o melhoramento dos processos de separação espermática em pouco tempo se converterá em uma prática de rotina nos estábulos (figura 7). -/- Figura 6: Uma técnica que aumenta a eficiência na detecção dos estros consiste em pintar a região da grupa. Quando esta pintura desaparece ou se nota que as novilhas estão "talhadas", devem ser apalpadas via retal para determinar se existem sinais genitais de estro. Acervo pessoal do autor. -/- Figura 7: As novilhas são as fêmeas mais férteis do rebanho, por isso o custo do sêmen por gestação é menor em comparação com as vacas adultas, o que permite investir em melhores touros e em sêmen sexado. Acervo pessoal do autor. 5. MONTA DIRIGIDA -/- A monta dirigida ou direta é uma opção prática e eficaz para emprenhar as novilhas. Neste sistema se introduz um touro com um grupo de novilhas, para que ele se encarregue de encontrar as fêmeas em estro e proceder a monta. Em rebanhos comerciais, o ideal é a utilização de um touro para 25 fêmeas. No entanto, com este manejo perde-se a oportunidade de utilizar a inseminação artificial e, com isso, a possibilidade de melhoria genética. -/- 6. PROGRAMAS DE SINCRONIZAÇÃO DE ESTROS -/- Os tratamentos para sincronizar o estro das novilhas possuem os mesmos fundamentos que os utilizados nas vacas. -/- 6.1 Prostaglandina F2a -/- A PGF2α é utilizada para a sincronização de estros em grupos de novilhas, e também é utilizada para a indução do estro individualmente, nas fêmeas que são examinadas por via retal e têm um corpo lúteo. A resposta dos animais tratados é variável; em novilhas pode-se alcançar até 95% de animais em estro. O tempo de manifestação do estro após a injeção é de 48 a 120 horas. -/- 6.1.1 Dupla injeção de PGF2a -/- Além da sincronização dos animais selecionados pela presença de um corpo lúteo diagnosticado por palpação retal, existem dois programas que não incluem a palpação retal. Por exemplo, na segunda-feira, ou no dia preferido, injeta-se PGF2α em todas as novilhas que se deseja inseminar. Cerca de 50% das novilhas manifestarão estro nas próximas 48 a 120 horas. As fêmeas que não mostrarem estro receberão uma segunda injeção na segunda-feira seguinte (intervalo de sete dias). As que apresentaram estro com a primeira injeção teriam um corpo lúteo nesse momento, enquanto as que não o manifestaram estavam em estro ou em metaestro; assim, ao repetir o tratamento sete dias depois, estas últimas novilhas teriam um corpo lúteo e responderiam à PGF2α (figura 8). No outro programa, é administrada duas doses de PGF2α com 11 dias de separação/intervalo. As novilhas podem ser inseminadas no estro observado, após qualquer uma das duas injeções. Este programa oferece uma boa sincroniza- ção após a segunda injeção e é o programa de escolha na sincronização das novilhas receptoras de embriões (figura 9). -/- Figura 8: Sincronização do estro com dupla injeção de PGF2a com 7 dias de diferença/intervalo. Elaborado pelo autor. -/- Figura 9: Sincronização do estro com dupla injeção de PGF2a com 11 dias de diferença/intervalo. Elaborado pelo autor. -/- 6.2 Progestágenos -/- Existe um tratamento que consiste na inserção, na parte externa da orelha, de um implante que contém norgestomet, que permanece na região auricular por nove dias. Além disso, o tratamento é complementado com a injeção intramuscular de valerato de estradiol e norgestomet, no momento da colocação do implante. O tempo de apresentação do estro a partir da remoção do implante é de 48 a 72 horas e a proporção de animais em estro muitas vezes se torna maior do que 80%. Outro tratamento é baseado na inserção intravaginal de dispositivos de liberação de progesterona. O dispositivo pode ser utilizado durante 12 dias ou o período de exposição pode ser encurtado, desde que seja acompanhado da injeção de uma dose luteolítica de PGF2α, um dia antes ou no momento da remoção do dispositivo. A fertilidade global conseguida após o serviço no estro sincronizado é similar à obtida no estro natural; porém, algumas novilhas são menos férteis, o que está associado com alterações no desenvolvimento folicular e alterações na relação temporal entre o estro e a ovulação. Observou-se que o tratamento com implantes de norgestomet combinados com a injeção de valerato de estradiol pode induzir comportamento estral em animais que não estão ciclando normalmente. Isso ocorre porque os níveis de estradiol, administrados no primeiro dia, persistem até o momento da remoção do implante. Assim, ao remover a fonte do progestágeno e ao haver concentrações altas de estradiol se desencadeia o estro, o qual em novilhas anéstricas não é acompanhado de ovulação, enquanto que em novilhas ciclando se altera a relação temporal entre o estro, pico pré-ovulatório de LH e ovulação. Bons resultados são alcançados quando o valerato de estradiol não é administrado e é substituído por uma injeção de PGF2α no momento da remoção do implante. Outro fator que tem sido associado com baixa fertilidade é o dia do ciclo em que o tratamento começa. Observou-se que quando coincide com a presença de um corpo lúteo (diestro), a porcentagem de concepção é maior do que quando não há um corpo lúteo (proestro). Isto ocorre porque a concentração sérica do progestágeno, por si só, não é capaz de suprimir a secreção pulsátil de LH, o que faz com que o folículo dominante presente no momento de iniciar o tratamento não sofra atresia e persista até o dia da retirada do progestágeno, convertendo-se no folículo ovulatório. Com isso, o folículo já envelheceu e o ovócito já sofreu alterações que reduzem o seu potencial para desenvolver um embrião viável. Quando o tratamento coincide com a presença de um corpo lúteo, a secreção de LH é efetivamente suprimida devido ao efeito aditivo da progesterona secretada pelo corpo lúteo e do progestágeno exógeno, inserido na vaca, o que provoca a reposição folicular. Em condições de campo, a seleção das vacas pela presença de um corpo lúteo antes de iniciar o tratamento com progestágenos é impraticável, uma vez que não é possível visualizá-lo, além disso essa prática/seleção não faria sentido, já que seria mais fácil tratar estes animais com dose ou doses de PGF2α. Atualmente existem tratamentos para eliminar folículos dominantes e promover uma nova onda folicular. -/- 6.3 Progestágenos orais -/- O acetato de melengestrol (MGA) é um progestágeno administrado por via oral. Em fêmeas bovinas é utilizado para melhorar a eficiência alimentar nos currais de engorda, o que se consegue através da inibição da apresentação do estro. Como todos os progestágenos, o MGA inibe a secreção de LH, eliminando assim a maturação do folículo e a ovulação. Após a remoção do MGA, o folículo dominante termina o seu desenvolvimento e as fêmeas apresentam estro em forma sincronizada. A dose de MGA por novilha é de 0,5 a 1 mg por dia, em tratamentos que variam de 9 a 14 dias. A apresentação comercial de MGA contém 0,22 mg do hormônio por 1 g do produto. O MGA pode ser facilmente misturado com qualquer concentrado ou grão moído. Após o último dia de tratamento, o estro se apresenta de dois a seis dias. O intervalo de remoção do MGA ao estro é mais longo quando comparado com outros progestágenos. Isto deve-se ao tempo de remoção do MGA, uma vez que enquanto um implante ou dispositivo intravaginal é removido abruptamente, o MGA pode continuar a ser absorvido enquanto é removido do trato gastrointestinal. Com tratamentos de 14 dias podem-se obter porcentagens de concepção menores em comparação com o estro natural, o que se deve em grande parte à ovulação de folículos persistentes. Um tratamento eficaz, que também melhora a fertilidade, consiste na administração de MGA durante 14 dias, seguido de uma injeção de PGF2α 15 ou 17 dias após a remoção do progestágeno. Com este programa, uma alta proporção de fêmeas teriam um corpo lúteo no momento da injeção da PGF2α e apresentariam estro com boa sincronização. Outro tratamento eficaz consiste na administração do MGA durante nove dias, mais uma dose de PGF2α ao nono dia; com este programa também se obtêm bons resultados em sincronização do estro e fertilidade. Este tratamento foi avaliado com novilhas holandesas e a porcentagem de fêmeas sincronizadas é elevada (95%). A porcentagem de concepção é semelhante à obtida no estro natural. Estes resultados são comparáveis aos obtidos com outros programas, como implantes de norgestomet ou dispositivos intravaginais de liberação de progesterona, mas com um custo significativamente menor (figura 10). -/- 6.4 Sincronização da ovulação e inseminação em tempo fixo -/- Em contraste com o observado em vacas em lactação, a resposta das novilhas aos programas de sincronização da ovulação e inseminação a tempo fixo é deficiente, o que se reflete em porcentagens de concepção de 20 a 35% menores que as novilhas inseminadas no estro natural. A causa desta resposta está relacionada com diferenças no desenvolvimento folicular; assim, nas novilhas o tempo de desenvolvimento do folículo dominante é mais rápido e o tempo de domínio é mais curto do que nas vacas em lactação. Desta forma, o folículo da onda folicular sincronizada com a injeção de GnRH sofre atresia antes da injeção de PGF2α, de tal forma que quando se induz a ovulação com a segunda injeção de GnRH, as novilhas têm folículos em diferentes estádios de desenvolvimento, o que provoca assincronia entre a ovulação e a inseminação artificial. -/- Figura 10: Programa de sincronização do estro com Acetato de Melengestrol (MGA). Elaborado pelo autor. -/- 7. MANEJO DO ANESTRO -/- Uma vez que as novilhas atingem a puberdade, apresentam ciclos estrais em intervalos de 21 dias que só são interrompidos pela gestação ou por alguma patologia. O anestro patológico é raro em novilhas; no entanto, surgem casos de piometra e cistos luteinizados, que são tratados com uma dose de PGF2α. Também se observam anormalidades de desenvolvimen- to, tais como freemartinismo e hipoplasia genital, patologias que não têm tratamento; somente 8% das novilhas freemartin são férteis. O anestro funcional (as novilhas manifestam estro, mas não são detectadas) é frequen- te e está diretamente relacionado com a eficiência na detecção de estros. As novilhas com idade e peso para se integrarem no programa reprodutivo e não apresentarem sinais de estro devem ser examinadas retalmente para diagnosticar a causa do anestro. Se, durante a palpação retal, as novilhas tiverem um corpo lúteo são tratadas nesse momento com PGF2α, os animais sem corpo lúteo podem receber uma injeção de PGF2α, sete dias depois. Este programa sincroniza o estro e aumenta a probabilidade de o detectar (figura 11). -/- Figura 11: As novilhas com idade e peso para se integrarem no programa reprodutivo e não mostrarem sinais de estro devem ser verificadas via retal para diagnosticar a causa do anestro. Arquivo pessoal do autor. -/- 8. MANEJO DA NOVILHA INFÉRTIL -/- A fertilidade das vacas leiteiras diminuiu nos últimos 30 anos, enquanto a fertilidade das novilhas não se alterou; após a primeira inseminação, entre 60 e 70% das novilhas emprenham. O objetivo do programa reprodutivo é conseguir que 90% das novilhas gestem nos primeiros três serviços. Desta forma, esta proporção de animais daria à luz antes dos 25 meses de idade. É comum que 10% das novilhas se transformem em animais repetidores, ou seja, novilhas com mais de três serviços inférteis. A causa da falha na concepção de novilhas deve-se principalmente à morte embrionária precoce. Uma causa importante da falha na concepção das novilhas repetidoras são as patologias adquiridas no aparelho reprodutivo; é comum encontrar aderências ovarianas e salpingite. Provavelmente, esses problemas são consequência de alguma infecção adquirida durante a criação. Diversos tratamentos hormonais têm sido testados para resolver o problema de infertilidade em novilhas repetidoras e os resultados obtidos ainda são deficientes. Como estes tratamentos não apresentam resultados consistentes, a melhor forma de mitigar o problema de infertilidade nas novilhas é melhorando as práticas de inseminação, ou seja, o momento da inseminação, o manejo do sêmen e a técnica de inseminação empregada. Além disso, a melhor técnica para aumentar a proporção de novilhas prenhes no rebanho é aumentar a eficiência da detecção de estros. -/- 9. RESUMO -/- As novilhas devem parir aos dois anos de idade (23 a 25 meses). O peso ao parto deve ser de 550 a 580 kg. O manejo reprodutivo começa aos 14 ou 15 meses de idade, com um peso de 350 a 370 kg. As palhetas de sêmen sexado contêm de 2 a 3 milhões de espermatozoides. As doses de sêmen não sexado contêm de 20 a 30 milhões de espermatozoides. A porcentagem de concepção das novilhas inseminadas com sêmen sexado é 10 a 20% menor do que com sêmen não sexado. Com sêmen sexado se obtém entre 90 e 95% de fêmeas. A porcentagem de concepção com programas de IATF é de 20 a 35% menor que nas novilhas inseminadas no estro natural. Cerca de 90% das novilhas devem ficar prenhes nos primeiros três serviços. Devem ser produzidas novilhas para substituir as vacas que são descartadas anualmen- te (25 a 35%). Espera-se que um gado leiteiro tenha ao dispor uma população de animais de reposição, desde um dia de vida até a etapa de novilha ao parto, correspondente a, pelo menos, 70 % do total das vacas. -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- AUAD, Alexander Machado et al.

The proposed paper presents an argument in favor of a Rawlsian approach to ethics for Internet technology companies (den Hoven & Rooksby, 2008; Hoffman, 2017). Ethics statements from such companies are analyzed and shown to be utilitarian and teleological in nature, and therefore in opposition to Rawls’ theories of justice and fairness. The statements are also shown to have traits in common with Confucian virtue ethics (Ames, 2011; Nylan, 2008).

The starting point of this paper is the thought that the phenomenal appearances that accompany mental states are somehow only there, or only real, from the standpoint of the subject of those mental states. The world differs across subjects in terms of which appearances obtain. Not only are subjects standpoints across which the world varies, subjects are standpoints that we can ‘adopt’ in our own theorizing about the world (or stand back from). The picture that is suggested by these claims (...) has an appeal but is at the same time obscure and stands in need of regimentation. This paper explores and motivates a metaphysical account of what it is for subjects to be standpoints, what it is to adopt standpoints in our representations and, most importantly, how these notions might help us better understand the subjective character of conscious mental states. Some well-known observations by Thomas Nagel serve as starting points and the paper concludes by revisiting Nagel’s argument for the inevitable incompleteness of objective accounts of mental states, which will be reframed in terms of the central commitments of the proposed framework.

It is widely accepted that there is a visual field, but the analogous notion of an auditory field is rejected by many philosophers on the grounds that the metaphysics or phenomenology of audition lack the necessary spatial or phenomenological structure. In this paper, I argue that many of the common objections to the existence of an auditory field are misguided and that, contrary to a tradition of philosophical scepticism about the spatiality of auditory experience, it is as richly spatial as (...) visual experience—and in some ways even more so. By carefully considering the spatiality and boundedness of audition, along with how sounds or their sources are experienced as occurring within the surrounding acoustic environment, we can gain a better understanding of (i) our auditory experience of space and (ii) the conditions for the existence of spatial sensory fields in general in a way that does not privilege vision over the other senses.

Academic institutions migrated to modular teaching-learning amid the COVID-19 pandemic. To ensure the quality of the pedagogical innovations employed, the study determined the students’ evaluation of the faculty prepared instructional modules for the courses they enrolled in during the first and second semesters of Academic Year 2020-2021. Employing a descriptive-correlational research design, the study was participated by 644 students from three colleges who were then available during the data gathering. Data gathered through online surveys were then analyzed using descriptive statistics (...) and Spearman's rank correlation coefficient utilizing jamovi software. Results revealed that the faculty-prepared instructional modules were acceptable and satisfactory to the students. Besides, the students' evaluation of the instructional modules was positively related to their level of satisfaction. Still, the students recommended that a review of the modules be done before sending the modules; a more extended time allotment is considered, and sufficient concrete examples are given in the modules. With this, the faculty concerned are encouraged to review the phases involved in the design, development, and distribution of the instructional modules to make them highly acceptable and very satisfactory to the students while maintaining the quality of both the content and aesthetics of the learning materials. Considering the study’s limitations, further endeavors may be carried out to validate this pedagogical innovation. (shrink)

We show that early vision can use monocular cues to rapidly complete partially-occluded objects. Visual search for easily detected fragments becomes difficult when the completed shape is similar to others in the display; conversely, search for fragments that are difficult to detect becomes easy when the completed shape is distinctive. Results indicate that completion occurs via the occlusion-triggered removal of occlusion edges and linking of associated regions. We fail to find evidence for a visible filling-in of contours or surfaces, but (...) do find evidence for a "functional" filling-in that prevents the constituent fragments from being rapidly accessed. As such, it is only the completed structures—and not the fragments themselves—that serve as the basis for rapid recognition. (shrink)

In two very influential papers from 2008, Tamar Gendler introduced the concept of “alief” to describe the mental state one is in when acting in ways contrary to their consciously professed beliefs. For example, if asked to eat what they know is fudge, but shaped into the form of dog feces, they will hesitate, and behave in a manner that would be consistent with the belief that the fudge is really poop. They alieve that it is disgusting, while they believe (...) it is not. This paper investigates laughter from self-proclaimed egalitarian, tolerant folk, in response to oppressive jokes that might fit the alief-model. If I merely alieve the content of a joke at which I laugh, will that constitute morally exculpating reasons for such laughter? And what else might it imply? This paper will provide insights at the intersections of humor studies, ethics, epistemology, phenomenology, and the philosophy of mind, all while being moderately and appropriately amusing.

When hospitals face surges of patients with COVID-19, fair allocation of scarce medical resources remains a challenge. Scarcity has at times encompassed not only hospital and intensive care unit beds—often reflecting staffing shortages—but also therapies and intensive treatments. Safe, highly effective COVID-19 vaccines have been free and widely available since mid-2021, yet many Americans remain unvaccinated by choice. Should their decision to forgo vaccination be considered when allocating scarce resources? Some have suggested it should, while others disagree. We offer a (...) framework for evaluating when it is ethical and briefly discuss its legality in American law. (shrink)

How, if at all, consciousness can be part of the physical universe remains a baffling problem. This article outlines a new, developing philosophical theory of how it could do so, and offers a preliminary mathematical formulation of a physical grounding for key aspects of the theory. Because the philosophical side has radical elements, so does the physical-theory side. The philosophical side is radical, first, in proposing that the productivity or dynamism in the universe that many believe to be responsible for (...) its systematic regularities is actually itself a physical constituent of the universe, along with more familiar entities. Indeed, it proposes that instances of dynamism can themselves take part in physical interactions with other entities, this interaction then being “meta-dynamism” (a type of meta-causation). Secondly, the theory is radical, and unique, in arguing that consciousness is necessarily partly constituted of meta-dynamic auto-sensitivity, in other words it must react via meta-dynamism to its own dynamism, and also in conjecturing that some specific form of this sensitivity is sufficient for and indeed constitutive of consciousness. The article proposes a way for physical laws to be modified to accommodate meta-dynamism, via the radical step of including elements that explicitly refer to dynamism itself. Additionally, laws become, explicitly, temporally non-local in referring directly to quantity values holding at times prior to a given instant of application of the law. The approach therefore implicitly brings in considerations about what information determines states. Because of the temporal non-locality, and also because of the deep connections between dynamism and time-flow, the approach also implicitly connects to the topic of entropy insofar as this is related to time.

In Plato’s Protagoras, Socrates argues that ‘the many’ are confused about the experience they describe as ‘being overcome by pleasure’. They think the cause is ‘something other than ignorance’. He argues it follows from what they believe that the cause is ‘ignorance’ and ‘false belief’. I show that his argument depends on a premise he does not introduce but they should deny: that when someone is overcome by pleasure, the desire stems from a belief. To explain why Plato does not (...) make Socrates introduce this premise, the account I construct is speculative. It starts from the assumption that Plato is thinking through an understanding of human beings and what they must do to live good lives that he takes the historical Socrates to set out. (shrink)

It is increasingly acknowledged that creativity cannot be fully understood without considering the setting where it takes place. Building on this premise, we use the concepts of niche construction, scaffolding, coupling, and functional integration to expound on the environmentally situated nature of painters’ studio work. Our analysis shows studios to be multi-resource niches that are customized by artists to support various capacities, states, and actions crucial to painting. When at work in these personalized spaces, painters do not need to rely (...) solely on their “inner” powers of imagination, memory, decision making, and technique to execute their paintings. Instead, with the help of carefully selected resources, they can offload elements of creative mentation and action onto the studio niche and enact different forms of a creative agency. To put more flesh on these ideas, we examine how painters use existing artworks, memory aids, and music to scaffold the creative process. Overall, our analysis illuminates underexamined aspects of environmentally situated creativity and demonstrates the broader utility of the applied concepts for future creativity research. (shrink)

For scatterplots with gaussian distributions of dots, the perception of Pearson correlation r can be described by two simple laws: a linear one for discrimination, and a logarithmic one for perceived magnitude (Rensink & Baldridge, 2010). The underlying perceptual mechanisms, however, remain poorly understood. To cast light on these, four different distributions of datapoints were examined. The first had 100 points with equal variance in both dimensions. Consistent with earlier results, just noticeable difference (JND) was a linear function of the (...) distance away from r = 1, and the magnitude of perceived correlation a logarithmic function of this quantity. In addition, these laws were linked, with the intercept of the JND line being the inverse of the bias in perceived magnitude. Three other conditions were also examined: a dot cloud with 25 points, a horizontal compression of the cloud, and a cloud with a uniform distribution of dots. Performance was found to be similar in all conditions. The generality and form of these laws suggest that what underlies correlation perception is not a geometric structure such as the shape of the dot cloud, but the shape of the probability distribution of the dots, likely inferred via a form of ensemble coding. It is suggested that this reflects the ability of observers to perceive the information entropy in an image, with this quantity used as a proxy for Pearson correlation. (shrink)

Can video games or the playing of such games be morally objectionable? Many attempts to justify our intuitions about the morality of certain games or game activities are either unsuccessful or fall short. This is mainly due to a normative gap between reality and virtuality that classical approaches to moral philosophy cannot bridge. I am investigating to what extent an accurate action analysis can help us to justify our intuitions that, in some cases, something is ethically wrong with video games. (...) To do so, I am using Frankfurt’s volition theory to show how virtual game actions can be evaluated based on virtue ethics. This virtue ethical assessment is compatible with Ostritsch’s (2017) endorsement view. Especially in light of the gamification of our surroundings, the question of the ethical status of video gaming is becoming more and more urgent. By arguing that a virtue ethical approach can tell us more about the ethical aspects of video gaming, I will also argue that virtue ethics (because of similar problems in these fields) is promising regarding the ethics of simulation, art, and literature.

The idea that there are five senses dates back to Aristotle, who was one of the first philosophers to examine them systematically. Though it has become conventional wisdom, many scientists and philosophers would argue that this idea is outdated and inaccurate. Indeed, they have given many different answers to this question, ranging from just three (the number of different kinds of physical energy we can detect) to 33 or more senses. Perhaps surprisingly, the issue remains controversial, partly because it is (...) not clear exactly what should count as a ‘sense’. Should proprioception, balance and kinaesthesis, amongst others, be considered additional senses? And if so, how do we figure out how many senses we really have? -/- (Published in Turkish under the title ‘Çok Duyumlu Algi’). (shrink)

As observers, we generally have a strong impression of seeing everything in front of us at any moment. But compelling as it is, this impression is false – there are severe limits to what we can consciously experience in everyday life. Much of the evidence for this claim has come from two phenomena: change blindness (CB) and inattentional blindness (IB). -/- CB refers to the failure of an observer to visually experience changes that are easily seen once noticed. This can (...) happen even if the changes are large, constantly repeat, and the observer has been informed that they will occur. A related phenomenon is IB – the failure to visually experience an object or event when attention is directed elsewhere. For example, observers may fail to notice an unexpected object that enters their visual field, even if this object is large, appears for several seconds, and has important consequences for the selection of action. -/- Both phenomena involve a striking failure to report an object or event that is easily seen once noticed. As such, both are highly counterintuitive, not only in the subjective sense that observers have difficulty believing they could fail so badly at seeing but also in the objective sense that these findings challenge many existing ideas about how we see. But as counterintuitive as these phenomena are, progress has been made in understanding them. Indeed, doing so has allowed us to better understand the limitations of human perception in everyday life and to gain new insights into how our visual systems create the picture of the world that we experience each moment our eyes are open.

Visual perception is widely taken to present properties such as redness, roundness, and so on. This in turn might be thought to give rise to accuracy conditions for experience, and so content, regardless of which metaphysical view of perception one endorses. An influential version of this argument—Susanna Siegel’s ’Argument from Appearing’—aims to establish the existence of content as common ground between representational and relational views of perception. This goes against proponents of ‘austere’ relationalism who deny that content plays a substantive (...) role in philosophical explanations of conscious perceptual experience. Though Siegel’s argument purports to be neutral with respect to the metaphysics of perception, it relies upon an equivocation between the presentation of property-types and property-instances. Consequently, the argument begs the question against the austere relational view, and so fails to establish the desired conclusion. So while relationalists can and should allow that experiences have accuracy conditions, it does not follow from this that they have contents of any philosophically interesting or significant kind.

Each of our sensory modalities—vision, touch, taste, etc.—works on a slightly different timescale, with differing temporal resolutions and processing lag. This raises the question of how, or indeed whether, these sensory streams are co-ordinated or ‘bound’ into a coherent multisensory experience of the perceptual ‘now’. In this paper I evaluate one account of how temporal binding is achieved: the temporal windows hypothesis, concluding that, in its simplest form, this hypothesis is inadequate to capture a variety of multisensory phenomena. Rather, the (...) evidence suggests the existence of a more complex temporal structure in which multiple overlapping windows support distinct functional mechanisms. To aid in the precise formulation of such views, I propose a taxonomy of temporal window types and their characteristics that in turn suggests promising avenues for future empirical and philosophical research. I conclude by examining some philosophical implications of multi-window models for the metaphysics of perception and perceptual experience more generally. (shrink)

This article discusses several key issues concerning the study of attention and its relation to visual perception, with an emphasis on behavioral and experiential aspects. It begins with an overview of several classical works carried out in the latter half of the 20th century, such as the development of early filter and spotlight models of attention. This is followed by a survey of subsequent research that extended or modified these results in significant ways. It covers current work on various forms (...) of induced blindness and on the capabilities of nonattentional processes. It also includes proposals about how a "just-in-time" allocation of attention can create the impression that we see our surroundings in coherent detail everywhere, as well as how the failure of such allocation can result in various perceptual deficits. The final section examines issues that have received little consideration to date, but may be important for new lines of research in the near future. These include the prospects for a better characterization of attention, the possibility of more systematic explanations, factors that may significantly modulate attentional operation, and the possibility of several kinds of visual attention and visual experience.

As social and interdependent beings, we have responsibilities to each other. One of them is to recognize each other appropriately. When we fail to meet this responsibility, we often stigmatize. In this paper, I argue that the COVID-19-related stigmatization is a variation of the lack of recognition understood as an orientation to our evaluative features. Various stereotypical behaviors regarding COVID-19 become stigmatized practices because of labeling, stereotyping, separation, status loss and discrimination, and power. When people stigmatize COVID-19 victims, they orient (...) themselves to their evaluative quality of being vulnerable to the SARS-CoV-2 virus by internalizing the victims as dangerous, understanding them as separable, and being motivated to act with them differently. All this causes the COVID-19 victims to lose status and suffer discrimination for which they do not experience participatory parity in different facets of their lives, rendering the COVID-19-related stigmatization an appalling example of misrecognition.

One of the benefits of hypertext in a connected digital environment is the ability to interlink documents. This was part of the hyper-text focused vision of the internet that Tim Berners-Lee was trying to create in the 1990s when he developed the World Wide Web.

In this paper, I propose to draw attention to a specific version of non-voluntaristic imperativism, its corresponding conception of legal norm, and the framework in which it is inserted: that advocated by Scandinavian realist Karl Olivecrona. In order to carry out this analysis, I will first contextualise Olivecrona’s position and his rejection of voluntarism; briefly reconstruct his position in relation to law and legal authority; and introduce the way in which authority and legal norms are articulated as cogs in the (...) machine of law (section 2). I will then analyse in depth Olivecrona’s conception of the legal norm as an independent imperative with a suggestive character, focusing on his rejection of the norm as a mandate and the elements of this type of legal imperative (section 3). Finally, I will focus on this particular conception of norms as independent imperatives and address some problems it raises, including the problem of their identification, the obscurity of the claim that these imperatives “guide behaviour”, and the appropriateness of the category of ‘suggestive character’ (section 4). I conclude the analysis with some brief reflections on the possible usefulness of the category of independent imperatives for at least two relevant and current topics in the philosophy of law (section 5).

According to the scientific image, aesthetic experience is constituted by private reverie or mindless gratification of some kind. This image fails to fully acknowledge the theoretical and hence cultural aspect of perception, which includes aesthetic experience. This chapter reframes aesthetic reflective judgment in terms of perceptual processes (section 2); intentional pleasure (section 3); non-perceptually represented perceptual properties (section 4); and intersubjectivity (section 5). By clarifying the relevant terms, the liberal naturalist account of the sublime provides the link between the sublime (...) and moral motivation (section 6). (shrink)

Neuroscientists have in recent years turned to building models that aim to generate predictions rather than explanations. This “predictive turn” has swept across domains including law, marketing, and neuropsychiatry. Yet the norms of prediction remain undertheorized relative to those of explanation. I examine two styles of predictive modeling and show how they exemplify the normative dynamics at work in prediction. I propose an account of how predictive models, conceived of as technological devices for aiding decision-making, can come to be adequate (...) for purposes that are defined by both their guiding research questions and their larger social context of application.

Advances in behavioral and brain sciences have engendered wide ranging efforts to help understand consciousness. The target article suggests that abstract computational models are ill-advised. This commentary broadens the discussion to include mysteries of subjective experience that are inconsistent with current neuroscience. It also discusses progress being made through demystifying specific cases and pursuing evolutionary considerations.

The Unified Foundational Ontology (UFO) was developed over the last two decades by consistently putting together theories from areas such as formal ontology in philosophy, cognitive science, linguistics, and philosophical logics. It comprises a number of micro-theories addressing fundamental conceptual modeling notions, including entity types and relationship types. The aim of this paper is to summarize the current state of UFO, presenting a formalization of the ontology, along with the analysis of a number of cases to illustrate the application of (...) UFO and facilitate its comparison with other foundational ontologies in this special issue. (The cases originate from the First FOUST Workshop – the Foundational Stance, an international forum dedicated to Foundational Ontology research.). (shrink)
