This encyclopedia article outlines the history of Latin American philosophy: the thinking of its indigenous peoples, the debates over conquest and colonization, the arguments for national independence in the eighteenth century, the challenges of nation-building and modernization in the nineteenth century, the concerns over various forms of development in the twentieth century, and the diverse interests in Latin American philosophy during the opening decades of the twenty-first century. Rather than attempt to provide an exhaustive and impossibly long list of scholars’ (...) names and dates, this article outlines the history of Latin American philosophy while trying to provide a meaningful sense of detail by focusing briefly on individual thinkers whose work points to broader philosophical trends that are inevitably more complex and diverse than any encyclopedic treatment can hope to capture.

This essay fills in some historical, conceptual, and pedagogical gaps that appear in the most visible and recent professional efforts to “revive” Philosophy as a Way of Life (PWOL). I present “American Philosophy and Self-Culture” as an advanced undergraduate seminar that broadens who counts in and what counts as philosophy by immersing us in the lives, writings, and practices of seven representative U.S.-American philosophers of self-culture, community-building, and world-changing: Benjamin Franklin (1706–1790), Frederick Douglass (1818–1895), William Ellery Channing (1780–1842), Henry David (...) Thoreau (1817–1862), Margaret Fuller (1810-1850), Henry Bugbee (1915–1999), and Gloria Anzaldúa (1942–2004). Students enter the class with preconceptions about who philosophers are, what they do, how they write, and the languages in which they write. Students walk out with new senses of self, place, and language that emerge through new ways of seeing, doing, and writing philosophy. (shrink)

My essay begins by providing a broad vision of how William James’s psychology and philosophy were a two-pronged attempt to revive the self whose foundations had collapsed after the Civil War. Next, I explain how this revival was all too successful insofar as James inadvertently resurrected the imperial self, so that he was forced to adjust and develop his philosophy of religion in keeping with his anti-imperialism. James’s mature philosophy of religion therefore articulates a vision of the radically ethical saint (...) religiously bound to a decidedly pluralistic universe. I evaluate James’s philosophy of religion by comparing it to Enrique Dussel’s psychological portrait of the imperialist ego, Dussel’s attempt to religiously bind this ego, and the more radical philosophy that results. I suggest that Dussel’s philosophy of liberation: 1) better theorizes the religious contraction of the self as a necessary part of ethical and political life and 2) offers a more concrete and radically democratic philosophy. My overarching aim is to show how Dussel’s liberation philosophy can help critically develop James’s pragmatist claim that religion might provide a force for widely and positively transforming our ethical and political lives.

This essay suggests that the U.S.-American Pragmatist tradition could be fruitfully reconstructed by way of a dialogue with Latin American Liberation Philosophy. More specifically, I work to establish a common ground for future comparative work by: 1) gathering and interpreting Enrique Dussel’s scattered comments on Pragmatism, 2) showing how the concept of liberation already functions in John Dewey’s Pragmatism, and 3) suggesting reasons for further developing this inter-American philosophical dialogue and debate.

In response to those calling for philosophical dialogue across the Americas, this paper considers the historical emergence of the concept of el pueblo (“the people”) as the subject and object of democracy. The first section makes a linguistic claim: the genuinely communal nature of “the people” clearly appears when considering el pueblo because it is unambiguously singular, grammatically speaking. The second section makes a historical claim: the microhistory of a largely indigenous pueblo in Mexico’s Yucatán enables us to begin unpacking (...) the complex concrete, historical, and genealogical dimensions of el pueblo. The brief concluding section suggests that historically contextualizing and concretizing el pueblo provides conceptual support for some of the premises that underwrite Latin American philosophies of liberation, including that of Enrique Dussel. -/- .

This article describes my ongoing attempts to more successfully engage the full linguistic repertoires and cultural identities of undergraduate students at a “Hispanic Serving Institution” (HSI) in South Texas by teaching a bilingual Introduction to Latin American Philosophy course in the “Language, Philosophy, and Culture” area of Texas’ General Education Core Curriculum. By uncovering the diverse identities, worldviews, and languages of those who were historically excluded from the Eurocentric discipline of philosophy through the conquest and colonization of the Americas, Latin (...) American philosophers offer us new ways of thinking and living by challenging Anglocentric language, philosophy, and culture. As part of the new B3 (Bilingual, Bicultural, and Biliterate) vision of the University of Texas Rio Grande Valley, the course is designed to draw upon the richly varied bilingualisms and biliteracies of predominantly Latinx students in order to help them honor, theorize, and cultivate their bicultural identities by “philosophizing in tongues” rather than being forced to assimilate to the monolingual and monocultural ideology that prevails across both mainstream Anglophone philosophy and the system of higher education in the United States of America.

Professor Morales’ Coss Dialogue Lecture demonstrates the utility of pragmatism for his work as a social scientist across three projects: 1) field research studying the acephalous and heterogenous social order of Chicago’s Maxwell Street Market; 2) nascent research how unseen religious orders animate the lives of im/migrants and their contributions to food systems; and 3) large-scale longitudinal research on farmers markets using the Metrics + Indicators for Impact (MIFI) toolkit. The first two sections of my paper applaud and build upon (...) Morales’ first two projects, and my extremely brief third section raises some questions about positivist specters that may haunt the MIFI project insofar as it is conceptualized, described, and deployed using the terms favored by mainstream social science.

This article describes why I used to teach Introduction to Latin American Philosophy monolingually in English, why I stopped, and how I am now teaching it using a flexible bilingual pedagogy, also sometimes called a translanguaging pedagogy, that has been transformative for my students and for me. By drawing upon the ventajas/assets y conocimientos/knowledge of our richly varied bilingualisms and biliteracies, the revised course contributes to the B3 (bilingual, bicultural, and biliterate) vision of the University of Texas Rio Grande Valley (...) (UTRGV).

Our paper examines Gloria Anzaldúa’s critical appropriation of Mexican philosophical sources, especially in the writing of Borderlands/La Frontera. We demonstrate how Anzaldúa developed a transnational Philosophy of Mexicanness, effectively contributing to what has been recently characterized as the “multi-generational project to pursue philosophy from and about Mexican circumstances” (Vargas). More specifically, we recover “La Mexicana en la Chicana” by paying careful attention to Anzaldúa’s Mexican sources, both those she explicitly cites and those we have discovered while conducting archival research using (...) the Gloria Evangelina Anzaldúa Papers from the Benson Latin American Collection at the University of Texas at Austin. The three sections of our paper: 1) define the terms Mexican and philosophy in conversation with Anzaldúa’s work, 2) examine the Mexican philosophical sources that Anzaldúa cites in Borderlands/La Frontera, and 3) present the other major Mexican philosophical influences on Anzaldúa that we have found in her archive. The eight Mexican philosophical sources we discuss here include: José Vasconcelos (1882-1959), Miguel León-Portilla (1926-2019), Juana Armanda Alegría (1938- ), Octavio Paz (1914-1998), Samuel Ramos (1897-1959), Rosario Castellanos (1925-1974), Sor Juana Inés de La Cruz (1648-1695), and Jorge Carrión (1913-2005).

Two fundamentally different perspectives on knowledge diffusion dominate debates about academic disciplines. On the one hand, critics of disciplinary research and education have argued that disciplines are isolated silos, within which specialists pursue inward-looking and increasingly narrow research agendas. On the other hand, critics of the silo argument have demonstrated that researchers constantly import and export ideas across disciplinary boundaries. These perspectives have different implications for how knowledge diffuses, how intellectuals gain and lose status within their disciplines, and how intellectual (...) reputations evolve within and across disciplines. We argue that highly general claims about the nature of disciplinary boundaries are counterproductive, and that research on the nature of specific disciplinary boundaries is more useful. To that end, this paper uses a novel publication and citation network dataset and statistical models of citation networks to test hypotheses about the boundaries between philosophy of science and 11 disciplinary clusters. Specifically, we test hypotheses about whether engaging with and being cited by scientific communities outside philosophy of science has an impact on one’s position within philosophy of science. Our results suggest that philosophers of science produce interdisciplinary scholarship, but they tend not to cite work by other philosophers when it is published in journals outside of their discipline. Furthermore, net of other factors, receiving citations from other disciplines has no meaningful impact—positive or negative—on citations within philosophy of science. We conclude by considering this evidence for simultaneous interdisciplinarity and insularity in terms of scientific trading theory and other work on disciplinary boundaries and communication.

Philosophers of science are increasingly arguing for the importance of doing scientifically- and socially-engaged work, suggesting that we need to reduce barriers to extra-disciplinary engagement and broaden our impact. Yet, we currently lack empirical data to inform these discussions, leaving a number of important questions unanswered. How common is it for philosophers of science to engage other communities, and in what ways are they engaging? What barriers are most prevalent when it comes to broadly disseminating one’s work or collaborating with (...) others? To what extent do philosophers of science actually value an engaged approach? Our project addresses this gap in our collective knowledge by providing empirical data regarding the state of philosophy of science today. We report the results of a survey of 299 philosophers of science about their attitudes towards and experiences with engaging those outside the discipline. Our data suggest that a significant majority of philosophers of science think it is important for non-philosophers to read and make use of their work; most are engaging with communities outside the discipline; and many think philosophy of science, as a discipline, has an obligation to ensure it has a broader impact. Interestingly, however, many of these same philosophers believe engaged work is generally undervalued in the discipline. We think these findings call for cautious optimism on the part of those who value engaged work—while there seems to be more interest in engaging other communities than many assume, significant barriers still remain.

BOOK REVIEW: Through fifteen interrelated essays, Daniel Campos’ Loving Immigrants in America reflects upon his experiences as a Latin American immigrant to the United States and develops an experiential philosophy of personal interaction. Building upon previous work, Campos’ implicit conceptual framework comes from Charles S. Peirce’s dual philosophical accounts of the evolution of personality and evolutionary love. But the flesh and blood of the book are Campos’ own personal experiences as an immigrant who has labored for more than twenty years (...) to make himself at home in the United States, aka la Yunai, by growing to love an impressively broad range of places and people across the country. Campos begins in rural Arkansas (where he arrived as an eighteen-year-old from Costa Rica to study at a small religious liberal arts college), travels extensively across the Deep South (in a series of road trips described in Chapters 3-6), completes an MA in Statistics and later a PhD in Philosophy at Penn State, and eventually settles to teach at Brooklyn College where he is surrounded by immigrants from all over the world. The book’s cast of characters and Campos’ interactions with them are so extensive as to defy generalization, but careful readers are likely to walk away convinced of Campos’ claim that “anyone who is receptive and attentive to the commonality of human experience can empathize with immigrants” (2).

In the first part of this article we survey general similarities and differences between biological and social macroevolution. In the second (and main) part, we consider a concrete mathematical model capable of describing important features of both biological and social macroevolution. In mathematical models of historical macrodynamics, a hyperbolic pattern of world population growth arises from non-linear, second-order positive feedback between demographic growth and technological development. Based on diverse paleontological data and an analogy with macrosociological models, we suggest that the (...) hyperbolic character of biodiversity growth can be similarly accounted for by non-linear, second-order positive feedback between diversity growth and the complexity of community structure. We discuss how such positive feedback mechanisms can be modelled mathematically. (shrink)

Host-microbiome interactions (HMIs) are critical for the modulation of biological processes and are associated with several diseases, and extensive HMI studies have generated large amounts of data. We propose that the logical representation of the knowledge derived from these data and the standardized representation of experimental variables and processes can foster integration of data and reproducibility of experiments and thereby further HMI knowledge discovery. A community-based Ontology of Host-Microbiome Interactions (OHMI) was developed following the OBO Foundry principles. OHMI leverages established (...) ontologies to create logically structured representations of microbiomes, microbial taxonomy, host species, host anatomical entities, and HMIs under different conditions and associated study protocols and types of data analysis and experimental results.

What is W. V. O. Quine’s relationship to classical pragmatism? Although he resists the comparison to William James in particular, commentators have seen an affinity between his “web of belief” model of theory confirmation and James’s claim that our beliefs form a “stock” that faces new experience as a corporate body. I argue that the similarity is only superficial. James thinks our web of beliefs should be responsive not just to perceptual but also to emotional experiences in some cases; Quine (...) denies this. I motivate James’s controversial view by appealing to an episode in the history of medicine when a researcher self-experimented by swallowing a vial of bacteria that at the time had not been studied in much detail. The researcher’s commitment to his own as-yet untested hypothesis was based in part on emotional considerations. Finally, I argue that Quine’s insistence that emotions can never be relevant to adjusting our web of belief reflects a tacit holdover of one of logical positivism’s crucially anti-pragmatist commitments—that philosophy of science should focus exclusively on the context of justification, not the context of discovery. James’s emphasis on discovery as a (perhaps the) crucial locus for epistemological inquiry is characteristic of pragmatism in general. Since Quinean epistemology is always an epistemology of justification, he is not happily viewed as a member of the pragmatist tradition. (shrink)

A reading is offered of Carl Hempel’s and Thomas Kuhn’s positions on, and disagreements about, rationality in science that relates these issues to the debate between W.V. Quine and Rudolf Carnap on the analytic/synthetic distinction.

G. Hegel in his Introduction to the History of Philosophy limits the initiation of this study to the field of the kind of thinking that emerged in Greece in the S. V ac, starting to do it that in other traditions (in which states, the Taoism, the religion of the Vedas, the Buddhism), the thinking is not autonomus in relation to a religious, mystical, mythological or customs justifications. Therefore there is no thought free of external determinations in these traditions. This (...) Hegelian principle has been accepted by the vast majority of those who carry out the study on the origin and history of philosophy. This paper intends to point out, following comments from experts in the field, how in certain traditions of Indian philosophy defined as nastika darshanas, and taking the Cārvāka materialism as example, philosophical thought occurs free from external determinations (religious, mythological, etc.), without prejudice to those philosophical systems which have been useful when justifying or discredit certain positions in these branches of human action.

"In the programs of Logic and History of Philosophy in the FHUCE study and introduction to logic is always done on the basis of Western classical Greek tradition, and its development is still exclusively through Western culture. This presentation aims to provide a path parallel to the West is the tradition of Nyaya-Vaisesika schools, which arise in the S. V B.C. like a response to the anti-Vedic Buddhist nihilism, and reached an important technical development at the beginning of S. II (...) D.C. when you know the Nyāyasutras attributed to Aksapada Gautama, and are considered the founding text of Nyāya tradition of Indian philosophy. The great virtue of the achievement of these schools is that although the system has Vaisesika been described as "a synthesis between philosophy of nature, ethics and soteriology" , which also applies to school Nyāya in the latter we are also a great emphasis on epistemology and the rules must be observed in philosophical debates. In their synthesis, Nyāya -Vaisesika system gets his language and jargon will be adopted by all who wish to discuss logical issues in India (especially in discussions Vedanta / Buddhism) without the need to adopt such language should assume his ontological, moral and religious premises.

Este discurso, encontrado entre os manuscritos de Berkeley, foi publicado pela primeira vez em 1871 por Alexander Campbell Fraser, em sua Collected Edition of the Works of Bishop Berkeley with Annotations.(LL pp. 598-604). No final do manuscrito, que atualmente se encontra no Museu Britânico, Berkeley registrou a data de 11 de janeiro de 1707/8. Berkeley tinha então 23 anos de idade. Isso indica que este discurso, próximo dos sermões que depois ele viria a escrever, foi escrito antes de ser (...) ordenado diácono da Igreja da Irlanda na capela do colégio do Trinity College de Dublin em 19 de fevereiro de 1709.

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 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.

Contemporary work on Boethius' Consolation of Philosophy often overlooks a discussion in CP.V.3 of a Peripatetic strategy for dissolving theological fatalism. Boethius’ treatment of this strategy and the lesson it provides about divine foreknowledge requires a reorientation of our understanding of the Consolation text. The result is that it is not foreknowledge nor any other temporally-conditioned knowledge that motivates Boethian concern but divine knowledge simpliciter.

We develop and defend a new approach to counterlogicals. Non-vacuous counterlogicals, we argue, fall within a broader class of counterfactuals known as counterconventionals. Existing semantics for counterconventionals, 459–482 ) and, 1–27 ) allow counterfactuals to shift the interpretation of predicates and relations. We extend these theories to counterlogicals by allowing counterfactuals to shift the interpretation of logical vocabulary. This yields an elegant semantics for counterlogicals that avoids problems with the usual impossible worlds semantics. We conclude by showing how this approach (...) can be extended to counterpossibles more generally. (shrink)

There are two families of influential and stubborn puzzles that many theories of aboutness (intentionality) face: underdetermination puzzles and puzzles concerning representations that appear to be about things that do not exist. I propose an approach that elegantly avoids both kinds of puzzle. The central idea is to explain aboutness (the relation supposed to stand between thoughts and terms and their objects) in terms of relations of co-aboutness (the relation of being about the same thing that stands between the thoughts (...) and terms themselves).

Can there be grounding without necessitation? Can a fact obtain wholly in virtue of metaphysically more fundamental facts, even though there are possible worlds at which the latter facts obtain but not the former? It is an orthodoxy in recent literature about the nature of grounding, and in first-order philosophical disputes about what grounds what, that the answer is no. I will argue that the correct answer is yes. I present two novel arguments against grounding necessitarianism, and show that grounding (...) contingentism is fully compatible with the various explanatory roles that grounding is widely thought to play.

I develop an expressivist account of verbal disagreements as practical disagreements over how to use words rather than factual disagreements over what words actually mean. This account enjoys several advantages over others in the literature: it can be implemented in a neo-Stalnakerian possible worlds framework; it accounts for cases where speakers are undecided on how exactly to interpret an expression; it avoids appeals to fraught notions like subject matter, charitable interpretation, and joint-carving; and it naturally extends to an analysis of (...) metalinguistic negotiations.

Many of my first students at Anzaldúa’s alma mater read Borderlands/La Frontera and concluded that Anzaldúa was not a philosopher. Hostile comments suggested that Anzaldúa’s intimately personal and poetic ways of writing were not philosophical. In response, I created “American Philosophy and Self-Culture” using backwards course design and taught variations of it in 2013, 2016, and 2018. Students spend nearly a month exploring Anzaldúa’s works, but only after reading three centuries of U.S.-American philosophers who wrote in deeply personal and literary (...) ways about self-transformation, community-building, and world-changing. The sections of this chapter: 1) describe why my first students rejected Anzaldúa as a philosopher in terms of the discipline’s parochialism; 2) present Anzaldúa’s broader understanding of herself as a philosopher; 3) summarize my reconstructed Anzaldúa-inspired American Philosophy course and outline some assignments; 4) discuss how my students respond to Borderlands/La Frontera when we read it through the lens of self-culture; and 5) explain my attempt to shape the subdiscipline of American Philosophy by teaching Anzaldúa to specialists at the 2017 Summer Institute in American Philosophy.

Review the Istvan Kiraly V.'s book: Death and History.

Discussion of the relevance of grounding to substantiveness, theory-choice, and “location problems” in metaphysics.

Individualist subjectivism is a position in metaethics which states that moral claims are descriptions of attitudes, e.g. 'murder is wrong' means 'I disapprove of murder'. In this short article I present a novel argument against it by appealing to the conversion between first-person and third-person claims. I argue that individualist subjectivism, and more broadly, any propositions which refer to the self without a word like 'I' or me', fail to account for the fact that person with the name X saying (...) 'I' could be rephrased as anybody saying 'X', a process I call 'personalisation'. (shrink)

Fine is widely thought to have refuted the simple modal account of essence, which takes the essential properties of a thing to be those it cannot exist without exemplifying. Yet, a number of philosophers have suggested resuscitating the simple modal account by appealing to distinctions akin to the distinction Lewis draws between sparse and abundant properties, treating only those in the former class as candidates for essentiality. I argue that ‘sparse modalism’ succumbs to counterexamples similar to those originally posed by (...) Fine, and fails to capture paradigmatic instances of essence involving abundant properties and relations. (shrink)

This is an introduction to the volume "Explanation Beyond Causation: Philosophical Perspectives on Non-Causal Explanations", edited by A. Reutlinger and J. Saatsi (OUP, forthcoming in 2017). -/- Explanations are very important to us in many contexts: in science, mathematics, philosophy, and also in everyday and juridical contexts. But what is an explanation? In the philosophical study of explanation, there is long-standing, influential tradition that links explanation intimately to causation: we often explain by providing accurate information about the causes of the (...) phenomenon to be explained. Such causal accounts have been the received view of the nature of explanation, particularly in philosophy of science, since the 1980s. However, philosophers have recently begun to break with this causal tradition by shifting their focus to kinds of explanation that do not turn on causal information. The increasing recognition of the importance of such non-causal explanations in the sciences and elsewhere raises pressing questions for philosophers of explanation. What is the nature of non-causal explanations - and which theory best captures it? How do non-causal explanations relate to causal ones? How are non-causal explanations in the sciences related to those in mathematics and metaphysics? This volume of new essays explores answers to these and other questions at the heart of contemporary philosophy of explanation. The essays address these questions from a variety of perspectives, including general accounts of non-causal and causal explanations, as well as a wide range of detailed case studies of non-causal explanations from the sciences, mathematics and metaphysics.

The prescriptive force of methodological rules rests, I argue, on the acceptance of scientific theories; that of the most general methodological rules rests on theories in the philosophy of science, which differ from theories in the several sciences only in generality and abstraction. I illustrate these claims by reference to methodological disputes in social science and among philosophers of science. My conclusions substantiate those of Laudan except that I argue for the existence of transtheoretical goals common to all scientists and (...) concrete enough actually to have bearing on methodology. And I argue that Laudan is committed to such goals himself, willy nilly. (shrink)

Proponents of evidence-based medicine have argued convincingly for applying this scientific method to medicine. However, the current methodological framework of the EBM movement has recently been called into question, especially in epidemiology and the philosophy of science. The debate has focused on whether the methodology of randomized controlled trials provides the best evidence available. This paper attempts to shift the focus of the debate by arguing that clinical reasoning involves a patchwork of evidential approaches and that the emphasis on evidence (...) hierarchies of methodology fails to lend credence to the common practice of corroboration in medicine. I argue that the strength of evidence lies in the evidence itself, and not the methodology used to obtain that evidence. Ultimately, when it comes to evaluating the effectiveness of medical interventions, it is the evidence obtained from the methodology rather than the methodology that should establish the strength of the evidence.

Otto Neurath’s empiricist methodology of economics and his contributions to politi- cal economy have gained increasing attention in recent years. We connect this research with contemporary debates regarding the epistemological status of thought experiments by reconstructing Neurath’s utopias as linchpins of thought experiments. In our three reconstructed examples of different uses of utopias/dystopias in thought experiments we employ a reformulation of Häggqvist’s model for thought experiments and we argue that: (1) Our reformulation of Häggqvist’s model more adequately complies with many (...) uses of thought experiments, especially with the open-ended discussions of utopias and dys- topias in thought experiments. (2) As a strict logical empiricist, Neurath is committed to a strictly empiricist account of thought experiments. John Norton’s empiricist argument view can indeed account for the justifications of empirical beliefs and genuine discoveries targeted by scientific utopianism in three distinct (yet connected) ways, all of which Neur- ath already contemplated: (2.I) Dealing with utopias and thought experiments on a regular basis increases creativity and inventiveness. (2.II) Particular ways of presenting knowl- edge facilitate scientific discovery and social progress. (2.III) The use of utopias in thought experiments can prompt conceptual change and allow access to new phenomena. We con- clude by highlighting that, even though thought experiments support a positive attitude for exploring new social possibilities, Neurath points out that active decisions are unavoidable. The exploration of alternatives and the awareness of a need for decisions in policy discus- sion avert a technocratic outlook in social science. (shrink)

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

Anscombe claims that whenever a subject is doing something intentionally, this subject knows that they are doing it. This essay defends Anscombe's claim from an influential set of counterexamples, due to Davidson. It argues that Davidson's counterexamples are tacit appeals to an argument, on which knowledge can't be essential to doing something intentionally, because some things that can be done intentionally require knowledge of future successes, and because such knowledge can't ever be guaranteed when someone is doing something intentionally. The (...) essay argues that there are apparently sensible grounds for denying each of these two premises. (shrink)

ABSTRACT. May scientists rely on substantive, a priori presuppositions? Quinean naturalists say "no," but Michael Friedman and others claim that such a view cannot be squared with the actual history of science. To make his case, Friedman offers Newton's universal law of gravitation and Einstein's theory of relativity as examples of admired theories that both employ presuppositions (usually of a mathematical nature), presuppositions that do not face empirical evidence directly. In fact, Friedman claims that the use of such presuppositions is (...) a hallmark of "science as we know it." But what should we say about the special sciences, which typically do not rely on the abstruse formalisms one finds in the exact sciences? I identify a type of a priori presupposition that plays an especially striking role in the development of empirical psychology. These are ontological presuppositions about the type of object a given science purports to study. I show how such presuppositions can be both a priori and rational by investigating their role in an early flap over psychology's contested status as a natural science. The flap focused on one of the field's earliest textbooks, William James's Principles of Psychology. The work was attacked precisely for its reliance on a priori presuppositions about what James had called the "mental state," psychology's (alleged) proper object. I argue that the specific presuppositions James packed into his definition of the "mental state" were not directly responsible to empirical evidence, and so in that sense were a priori; but the presuppositions were rational in that they were crafted to help overcome philosophical objections (championed by neo-Hegelians) to the very idea that there can be a genuine science of mind. Thus, my case study gives an example of substantive, a priori presuppositions being put to use—to rational use—in the special sciences. In addition to evaluating James's use of presuppositions, my paper also offers historical reflections on two different strands of pragmatist philosophy of science. One strand, tracing back through Quine to C. S. Peirce, is more naturalistic, eschewing the use of a priori elements in science. The other strand, tracing back through Kuhn and C. I. Lewis to James, is more friendly to such presuppositions, and to that extent bears affinity with the positivist tradition Friedman occupies. (shrink)

Conventional wisdom has it that truth is always evaluated using our actual linguistic conventions, even when considering counterfactual scenarios in which different conventions are adopted. This principle has been invoked in a number of philosophical arguments, including Kripke’s defense of the necessity of identity and Lewy’s objection to modal conventionalism. But it is false. It fails in the presence of what Einheuser (2006) calls c-monsters, or convention-shifting expressions (on analogy with Kaplan’s monsters, or context-shifting expressions). We show that c-monsters naturally (...) arise in contexts, such as metalinguistic negotiations, where speakers entertain alternative conventions. We develop an expressivist theory—inspired by Barker (2002) and MacFarlane (2016) on vague predications and Einheuser (2006) on counterconventionals—to model these shifts in convention. Using this framework, we reassess the philosophical arguments that invoked the conventional wisdom. (shrink)

A counterpossible is a counterfactual with an impossible antecedent. Counterpossibles present a puzzle for standard theories of counterfactuals, which predict that all counterpossibles are semantically vacuous. Moreover, counterpossibles play an important role in many debates within metaphysics and epistemology, including debates over grounding, causation, modality, mathematics, science, and even God. In this article, we will explore various positions on counterpossibles as well as their potential philosophical consequences.

Achieving space domain awareness requires the identification, characterization, and tracking of space objects. Storing and leveraging associated space object data for purposes such as hostile threat assessment, object identification, and collision prediction and avoidance present further challenges. Space objects are characterized according to a variety of parameters including their identifiers, design specifications, components, subsystems, capabilities, vulnerabilities, origins, missions, orbital elements, patterns of life, processes, operational statuses, and associated persons, organizations, or nations. The Space Object Ontology provides a consensus-based realist framework (...) for formulating such characterizations in a computable fashion. Space object data are aligned with classes and relations in the Space Object Ontology and stored in a dynamically updated Resource Description Framework triple store, which can be queried to support space domain awareness and the needs of spacecraft operators. This paper presents the core of the Space Object Ontology, discusses its advantages over other approaches to space object classification, and demonstrates its ability to combine diverse sets of data from multiple sources within an expandable framework. Finally, we show how the ontology provides benefits for enhancing and maintaining longterm space domain awareness. (shrink)
