How does consciousness vary across the animal kingdom? Are some animals ‘more conscious’ than others? This article presents a multidimensional framework for understanding interspecies variation in states of consciousness. The framework distinguishes five key dimensions of variation: perceptual richness, evaluative richness, integration at a time, integration across time, and self-consciousness. For each dimension, existing experiments that bear on it are reviewed and future experiments are suggested. By assessing a given species against each dimension, we can construct a consciousness profile for (...) that species. On this framework, there is no single scale along which species can be ranked as more or less conscious. Rather, each species has its own distinctive consciousness profile. (shrink)

This study examines the conflation of terms such as “knowledge” and “understanding” in peer-reviewed literature, and tests the hypothesis that little current research clearly distinguishes between importantly distinct epistemic states. Two sets of data are presented from papers published in the journal Public Understanding of Science. In the first set, the digital text analysis tool, Voyant, is used to analyze all papers published in 2014 for the use of epistemic success terms. In the second set of data, all papers published (...) in Public Understanding of Science from 2010–2015 are systematically analyzed to identify instances in which epistemic states are empirically measured. The results indicate that epistemic success terms are inconsistently defined, and that measurement of understanding, in particular, is rarely achieved in public understanding of science studies. We suggest that more diligent attention to measuring understanding, as opposed to mere knowledge, will increase efficacy of scientific outreach and communication efforts. (shrink)

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

Odată cu creșterea volumului de date pe Internet, în media socială, cloud computing, dispozitive mobile și date guvernamentale, Big Data devine în același timp o amenințare și o oportunitate în ceea ce privește gestionarea și utilizarea acestor date, menținând în același timp drepturile persoanelor implicate. În fiecare zi, folosim și generăm tone de date, alimentând bazele de date ale agențiilor guvernamentale, companiilor private și chiar cetățenilor privați. Beneficiem în multe feluri de existența și utilizarea Big Data, dar trebuie să ne (...) amintim de asemenea că „nu există nimic gratuit”. Există riscuri în utilizarea Big Data, un fel de parte întunecată. Schimbările de piață pot fi obținute prin utilizarea Big Data: în timp ce acestea pot fi pozitive pentru cineva, ele pot dăuna altcuiva. Riscurile potențiale provin și de la agențiile publice. Este clar că datele mari pot aduce beneficii cetățenilor și companiilor, dar trebuie să fie echilibrate de o conștientizare sporită a „părții întunecate” a Big Data în exploatarea noilor capacități și oportunități pe care le oferă tuturor . -/- CUPRINS -/- 1.

This essay centers on the notion of the symbolic and its impact as developed by Claude Lévi-Strauss in his Introduction to the Work of Marcel Mauss. I examine Lévi-Strauss’ formulation of the “floating signifier” and its influence in French thought, particularly in the work of Jacques Lacan and Jacques Derrida. In doing so, I argue that Lévi-Strauss’ notion may be a misreading of the structural linguistics of Ferdinand de Saussure that has important implications for contemporary political issues on the (...) left in both theory and practice.

This paper investigates the link between the consumer perception that a company is socially oriented and the consumer intention to buy products marketed by that company. We suggest that this link exists when at least two conditions prevail: (1) the products sold by that company comply with ethical and social requirements; (2) the company has an acknowledged commitment to protect consumer rights and interests. To test these hypotheses, we conducted a survey among the clients of retail chains offering Fair Trade (...) products. The results show that socially oriented companies can successfully leverage their reputation to market products with high symbolic values. (shrink)

dolce, the first top-level (foundational) ontology to be axiomatized, has remained stable for twenty years and today is broadly used in a variety of domains. dolce is inspired by cognitive and linguistic considerations and aims to model a commonsense view of reality, like the one human beings exploit in everyday life in areas as diverse as socio-technical systems, manufacturing, financial transactions and cultural heritage. dolce clearly lists the ontological choices it is based upon, relies on philosophical principles, is richly formalized, (...) and is built according to well-established ontological methodologies, e.g. OntoClean. Because of these features, it has inspired most of the existing top-level ontologies and has been used to develop or improve standards and public domain resources (e.g. CIDOC CRM, DBpedia and WordNet). Being a foundational ontology, dolce is not directly concerned with domain knowledge. Its purpose is to provide the general categories and relations needed to give a coherent view of reality, to integrate domain knowledge, and to mediate across domains. In these 20 years dolce has shown that applied ontologies can be stable and that interoperability across reference and domain ontologies is a reality. This paper briefly introduces the ontology and shows how to use it on a few modeling cases. (shrink)

There is no doubt that custard apple diseases are among the important reasons that destroy the Custard Apple plant and its agricultural crops. This leads to obvious damage to these plants and they become inedible. Discovering these diseases is a good step to provide the appropriate and correct treatment. Determining the treatment with high accuracy depends on the method used to correctly diagnose the disease, expert systems can greatly help in avoiding damage to these plants. The expert system correctly diagnoses (...) Custard Apple disease to make it easier for farmers to find the right treatment based on the appropriate diagnosis. Objectives: A specialized syllable language system was established for the diagnosis of Custard Apple plant disease. (shrink)

Moral grandstanding is the use of moral talk for self-promotion. Recent philosophical work assumes that people can often accurately identify instances of grandstanding. In contrast, we argue that people are generally unable to reliably recognize instances of grandstanding, and that we are typically unjustified in judging that others are grandstanding as a result. From there we argue that, under most circumstances, to judge others as grandstanders is to fail to act with proper intellectual humility. We then examine the significance of (...) these conclusions for moral discourse. More specifically, we propose that moral discourse should focus on others’ stated reasons and whether their actions manifest respect. (shrink)

RELAÇÃO E EFEITOS BIOQUÍMICO-NUTRICIONAIS SOBRE O CORPO LÚTEO PERSISTENTE EM VACAS E. I. C. da Silva Departamento de Agropecuária – IFPE Campus Belo Jardim Departamento de Zootecnia – UFRPE sede CORPO LÚTEO PERSISTENTE EM BOVINOS INTRODUÇÃO Essa alteração funcional da estrutura ovárica está relacionada com uma lise incompleta do corpo lúteo, o que leva à presença de níveis subnormais de progesterona bloqueando a ciclicidade ovárica ao retardar a retroalimentação para a ação dos estrogênios durante o proestro e o estro. Os (...) principais fatores associados à manifestação da permanência do corpo lúteo são as lesões do endométrio que bloqueiam a produção de prostaglandinas e as deficiências nutricionais (FRAZER, 2005; GORDON, 1996), sob essa última é importante citar: 8.1 Minerais (Manganês Mn) A deficiência de manganês em vacas alimentadas com rações que contenham menos de 22 mg de Mn por Kg-¹ de MS parece causar anestro, cios silenciosos, atrasos na ovulação, baixos níveis de gestações à primeira cobrição e nascimento de bezerros deformados. A infertilidade ocorre principalmente em animais que consomem pastagens que crescem em solos com deficiência de manganês ou que são fertilizados com grandes quantidades de calcita, ou que recebem suplementos que contêm quantidades excessivas de cálcio. Os bovinos possuem exigências distintas de Mn conforme sua categoria e aptidão, por exemplo, o gado de corte requerem 40 mg/kg de Mn presente na MS, porém esse número pode variar entre 20-50 mg/kg de MS; o gado de leite requer as mesmas 40 gramas por quilo de matéria seca, mas o intervalo segundo institutos de pesquisa gira em torno de 12-14 mg/kg de MS, o que é controverso. O nível máximo permitido de Mn presente na MS não deve ultrapassar os 1000 ppm por kg, para que não altere os mecanismos fisiológicos do sistema digestivo nem acarrete possíveis transtornos reprodutivos ou não. As fontes de suplementação do mineral para os animais são diversas, o pasto com as gramíneas, forrageiras e leguminosas suprem bem as exigências, porém se for o caso pode-se inserir o Mn por meio da ração ou via injetável através do sulfato de manganês. Esse manejo é para garantir a prevenção não só do corpo lúteo persistente, mas sim de tantas outras alterações na fertilidade dos animais. Sendo um cofator de enzimas como as fosfoglicomutase, piruvato carboxilase e fosfoenolpiruvato carboxil quinase, o manganês tem um papel fundamental na gliconeogênese. A diminuição dos níveis de manganês no útero acarreta numa redução da resposta tecidular à ação de estrogênios, o que causaria a presença de cios irregulares e silenciosos, bem como uma menor síntese de prostaglandina levando, como efeito, a uma menor eficiência na luteólise. A prevenção é o melhor remédio, e se for o caso de combater o transtorno os métodos mais utilizados são a utilização paulatinamente do mineral por meio da ração ou do pasto para obter os resultados gradativamente. Deve-se estar atento as quantidades e a qualidade, para que em vez da deficiência não acometa um novo transtorno mediante a supermineralização do animal. 8.2 Nitratos, nitritos e ferro (Fe) Outra anormalidade nutricional que afeta os processos luteolíticos gerando o corpo lúteo persistente é a alta concentração de nitratos que, mediante processos de redução ruminal, se convertem em nitritos. Os nitratos acumulam-se em forragens, fenos fertilizados com nitrogênio ou sob estresse térmico (HENDRIX, 2003). Os efeitos do NO3 na fermentação dos carboidratos pela flora ruminal estimulam a produção de acetato em detrimento dos ácidos graxos glicogênicos. Os nitritos afetam a troca gasosa por desacoplamento ferroso na hemoglobina, impedindo uma oxigenação correta dos tecidos. Não havendo troca gasosa entre oxigênio e o CO2, os tecidos retêm a forma carbonada freando a cadeia de elétrons e reduzindo seu potencial energético, dessa maneira obstrui-se a irrigação nas células da granulosa, e a síntese de algumas substâncias como as prostaglandinas, procedendo-se, como efeito, o corpo lúteo retido. Estudos realizados demonstraram que mesmo que a ingestão de nitratos seja em baixas doses, leva a problemas reprodutivos quando a metahemoglobinemia alcança os 30% (ou seja, 30% do Fe+2 da hemoglobina foi convertido a Fe+3). Os nitratos e os nitritos são encontrados na água dos animais, logo o criador deve fazer uma análise laboratorial para estudar a viabilidade de consumo da mesma. Os valores não poderão ser maiores que 220 ppm para NO3 e maiores que 40-100 de N- NO3. Com relação ao Fe o ideal é a ingestão de 50 mg/kg de MS para todas as idades, tendo um intervalo sugerido entre 50-100 mg/kg de MS para gado de corte e de 12,3-18 em gado leiteiro. Para suplementar esses animais com uma boa e adequada ingestão de Fe pelos animais os grãos de cereais possuem 30-60 mg de Fe/kg de MS; as oleaginosas possuem entre 100-200 mg de Fe/kg de MS; as farinhas de produtos de origem animal são as mais expressivas em teor de Fe tendo entre 400-3000 mg do mineral por kg de MS, mas vale salientar que níveis acima de 1000 ppm ou 1000 mg/kg o Fe já torna-se tóxico para o animal e, por fim, as forrageiras possuem entre 70-500 mg de Fe/kg de MS. Logo, caso haja deficiência do mineral no plantel o criador poderá optar pela inserção do mesmo na ração, água ou via suplementação mineral injetável (SMI). Se todos os manejos forem praticados os transtornos tanto do corpo lúteo persistente quanto de demais alterações ou patogenias, como a anemia ferropriva, expressiva em suínos e em bovinos menos comum, podem ser prevenidas e/ou combatidas. 8.3 Energia Outra causa corrente e importante de alterações na reprodução por causas nutricionais na vaca, é o fracasso dos sistemas digestivo e hepático para fornecer energia suficiente para a manutenção, exercício, crescimento, gestação e lactação. Os problemas de infertilidade podem ter origem na baixa capacidade gliconeogênica. Vários estudos sugerem que, nos ruminantes, o principal fator que regula a insulinogênese é a glicemia e que o propionato tem um baixo poder insulinogênico. Por conseguinte, baixos níveis de glicemia conduzem a baixos níveis de insulina plasmática provocando, indiretamente, as alterações na sequência gonadotrófica e induzindo lise luteal incompleta. Pouco se sabe sobre as vias específicas em que a informação sobre o estado nutricional é convertida em sinais neuroendócrinos que afetam a secreção de GnRH. Os mecanismos propostos incluem os possíveis papéis das hormonas envolvidas no metabolismo intermediário, particularmente a insulina. Recentemente, com a descoberta da leptina, abriu-se um novo campo de estudo para as relações entre o estado nutricional e a reprodução na vaca leiteira. A leptina ocorre no tecido adiposo e tem efeitos sobre o consumo de energia, a deposição de reservas, a liberação de LH e a resposta a FSH e LH em células hipofisárias e em células granulosas. A ação gonadotrófica de LH e particularmente de FSH, é conhecida por ser modulada por outros hormônios e fatores de crescimento. Estes incluem a insulina, GH e IGF-I, que desempenham um papel importante no metabolismo intermediário de energia e são, nutricionalmente, regulados por si mesmos. Estudos apontam que tanto a glicose como os esqueletos carbonados de aminoácidos ou insulina e IGF-I podem modular a taxa de ovulação independentemente da circulação de concentrações de FSH devido a efeitos diretos no ovário sobre o desenvolvimento folicular. Se a disponibilidade de fósforo para o metabolismo celular for reduzida, é provável que haja um desequilíbrio com o potássio, o que levaria a uma diminuição do fluxo de energia. O mais evidente de todos é uma intervenção na reação ATP—ADP + ~P. As características próprias dos recursos alimentares somadas à sua utilização inadequada têm originado nas vacas de explorações leiteiras de sistemas intensivos, uma série de desequilíbrios nutricionais generalizados, caracterizados por deficiência de energia, excesso de proteína crua e nitratos (NO3-), deficiências de fibra, de Ca, de Mg e algumas vezes excessos de P e K (GALVIS, et al. 2001). Essa problemática tem origem nas práticas irracionais de gestão da propriedade e principalmente dos animais no que tange a alimentação dos mesmos. Com relação ao pasto, a problemática origina-se sobre a excessiva fertilização e períodos curtos de rotação dos pastos, que dão lugar a pastagens com baixa quantidade de matéria seca, o que pode condicionar o consumo de forragens de qualidade questionável e favorecer o déficit energético. Esse déficit de energia no início da lactância diminui as concentrações de hormônio luteinizante (LH), o que leva a concluir que a alteração ovárica seria determinada por uma alteração na liberação pulsátil de LH, provavelmente ocasionada por uma liberação anormal e reduzida de GnRH, isso levaria a cios silenciosos e corpos lúteos persistentes. Superficialmente, vale sempre lembrar que a prevenção é a melhor opção numa criação de bovinos, logo, os macro ou micro minerais devem estar inseridos na dieta animal em quantidades estabelecidas para não manifestar uma deficiência ou supermineralização. O Ca deve ser presente entre 0,17-1,53% em kg/MS e numa concentração máxima de 2% kg/MS para não ser tóxico. O P deve ser fornecido entre 0,17-0,59% em kg/MS e menor que 1000 mg/kg de MS nível mínimo para toxidade. O K entre 0,6-1,0 mg por kg/MS, uma vaca de 600 kg deve ingerir um total de 230 mg/dia de K, o nível de toxidade do K é > 3% em kg/MS. O Mg entre 0,05-0,35 mg/dia, em um nível tóxico ≥ 1% em kg/MS. Esses minerais, como falado anteriormente e sempre frisado para o agricultor ter todo alicerce possível, se limita aos grãos de cereais, leguminosas, oleaginosas, farinhas de origem animal e vegetal, forrageiras e outras fontes alternativas. Para aclarar o supracitado texto, observe a tabela que contém o mineral, a quantidade ideal de fornecimento baseado ao requerimento animal, o nível de toxidade o alimento que mais contém determinado mineral e as vias possíveis de suplementação em caso de deficiência.

For over a decade now, a community of researchers has contributed to the development of the Unified Foundational Ontology (UFO) - aimed at providing foundations for all major conceptual modeling constructs. This ontology has led to the development of an Ontology-Driven Conceptual Modeling language dubbed OntoUML, reflecting the ontological micro-theories comprising UFO. Over the years, UFO and OntoUML have been successfully employed in a number of academic, industrial and governmental settings to create conceptual models in a variety of different domains. (...) These experiences have pointed out to opportunities of improvement not only to the language itself but also to its underlying theory. In this paper, we take the first step in that direction by revising the theory of types in UFO in response to empirical evidence. The new version of this theory shows that many of the meta-types present in OntoUML (differentiating Kinds, Roles, Phases, Mixins, etc.) should be considered not as restricted to Substantial types but instead should be applied to model Endurant Types in general, including Relator types, Quality types and Mode types. We also contribute a formal characterization of this fragment of the theory, which is then used to advance a metamodel for OntoUML 2.0. Finally, we propose a computational support tool implementing this updated metamodel. (shrink)

There has been a growing interest in research concerning memory modification technologies (MMTs) in recent years. Neuroscientists and psychologists are beginning to explore the prospect of controllable and intentional modification of human memory. One of the technologies with the greatest potential to this end is optogenetics—an invasive neuromodulation technique involving the use of light to control the activity of individual brain cells. It has recently shown the potential to modify specific long-term memories in animal models in ways not yet possible (...) with other MMTs. As the therapeutic potential of optogenetics has already prompted approval of the first human trials, it is especially important and timely to consider the opportunities and dangers this technology may entail. In this article, we focus on possible consequences of optogenetics as an MMT by analyzing fundamental threats potentially associated with memory modifications: the potential disruption of personality and authenticity.

The central focus of this paper is to motivate and explore the question, when is it permissible to endorse a psychologizing explanation of a sincere interlocutor? I am interested in the moral question of when (if ever) we may permissibly dismiss the sincere reasons given to us by others, and instead endorse an alternative explanation of their beliefs and actions. I argue that there is a significant risk of wronging the other person, and so we should only psychologize when we (...) are in a position to know that they are in bad faith. (shrink)

The purpose of this article is to show that animal rights are not necessarily at odds with the use of animals for research. If animals hold basic moral rights similar to those of humans, then we should consequently extend the ethical requirements guiding research with humans to research with animals. The article spells out how this can be done in practice by applying the seven requirements for ethical research with humans proposed by Ezekiel Emanuel, David Wendler and Christine Grady to (...) animal research. These requirements are i) social value, ii) scientific validity, iii) independent review, iv) fair subject selection, v) favorable risk-benefit ratio, vi) informed consent, and vii) respect for research subjects. In practice, this means that we must reform the practice of animal research to make it more similar to research with humans, rather than completely abolish the former. Indeed, if we banned animal research altogether, then we would also deprive animals of its potential benefits – which would be ethically problematic. (shrink)

Governments and social scientists are increasingly developing machine learning methods to automate the process of identifying terrorists in real time and predict future attacks. However, current operationalizations of “terrorist”’ in artificial intelligence are difficult to justify given three issues that remain neglected: insufficient construct legitimacy, insufficient criterion validity, and insufficient construct validity. I conclude that machine learning methods should be at most used for the identification of singular individuals deemed terrorists and not for identifying possible terrorists from some more general (...) class, nor to predict terrorist attacks more broadly, given intolerably high risks that result from such approaches.

Many of our most important goals require months or even years of effort to achieve, and some never get achieved at all. As social psychologists have lately emphasized, success in pursuing such goals requires the capacity for perseverance, or "grit." Philosophers have had little to say about grit, however, insofar as it differs from more familiar notions of willpower or continence. This leaves us ill-equipped to assess the social and moral implications of promoting grit. We propose that grit has an (...) important epistemic component, in that failures of perseverance are often caused by a significant loss of confidence that one will succeed if one continues to try. Correspondingly, successful exercises of grit often involve a kind of epistemic resilience in the face of failure, injury, rejection, and other setbacks that constitute genuine evidence that success is not forthcoming. Given this, we discuss whether and to what extent displays of grit can be epistemically as well as practically rational. We conclude that they can be (although many are not), and that the rationality of grit will depend partly on features of the context the agent normally finds herself in. In particular, grit-friendly norms of deliberation might be irrational to use in contexts of severe material scarcity or oppression. (shrink)

Optogenetics is an invasive neuromodulation technology involving the use of light to control the activity of individual neurons. Even though optogenetics is a relatively new neuromodulation tool whose various implications have not yet been scrutinized, it has already been approved for its first clinical trials in humans. As optogenetics is being intensively investigated in animal models with the aim of developing novel brain stimulation treatments for various neurological and psychiatric disorders, it appears crucial to consider both the opportunities and dangers (...) such therapies may offer. In this review, we focus on the memory-modifying potential of optogenetics, investigating what it is capable of and how it differs from other memory modification technologies. We then outline the safety challenges that need to be addressed before optogenetics can be used in humans. Finally, we re-examine crucial neuroethical concerns expressed in regard to other MMTs in the light of optogenetics and address those that appear to be unique to the memory-modifying potential of optogenetic technology.

The goal of the 2010 Ontology Summit was to address the current shortage of persons with ontology expertise by developing a strategy for the education of ontologists. To achieve this goal we studied how ontologists are currently trained, the requirements identified by organizations that hire ontologists, and developments that might impact the training of ontologists in the future. We developed recommendations for the body of knowledge that should be taught and the skills that should be developed by future ontologists; these (...) recommendations are intended as guidelines for institutions and organizations that may consider establishing a program for training ontologists. Further, we recommend a number of specific actions for the community to pursue. (shrink)

In recent years, there has been an increasing interest in thedevelopment of ontologically well-founded conceptual models for Information Systems in areas such as Service Management, Accounting Information Systems and Financial Reporting. Economic exchanges are central phenomena in these areas. For this reason, they occupy a prominent position in modelling frameworks such as the REA (Resource-EventAction) ISO Standard as well as the FIBO (Financial Industry BusinessOntology). In this paper, we begin a well-founded ontological analysisof economic exchanges inspired by a recent ontological (...) view on the nature of economic transactions. According to this view, what counts asan economic transaction is based on an agreement on the actions thatthe agents are committed to perform. The agreement is in turn based on convergent preferences about the course of action to bring about. This view enables a unified treatment of economic exchanges, regardless the object of the transaction, and complies with the view that all economictransactions are about services. In this paper, we start developing our analysis in the framework of the Unified Foundational Ontology (UFO). (shrink)

The idea that there could be spatially extended mereological simples has recently been defended by a number of metaphysicians (Markosian 1998, 2004; Simons 2004; Parsons (2000) also takes the idea seriously). Peter Simons (2004) goes further, arguing not only that spatially extended mereological simples (henceforth just extended simples) are possible, but that it is more plausible that our world is composed of such simples, than that it is composed of either point-sized simples, or of atomless gunk. The difficulty for these (...) views lies in explaining why it is that the various sub-volumes of space occupied by such simples, are not occupied by proper parts of those simples. Intuitively at least, many of us find compelling the idea that spatially extended objects have proper parts at every sub-volume of the region they occupy. It seems that the defender of extended simples must reject a seemingly plausible claim, what Simons calls the geometric correspondence principle (GCP): that any (spatially) extended object has parts that correspond to the parts of the region that it occupies (Simons 2004: 371). We disagree. We think that GCP is a plausible principle. We also think it is plausible that our world is composed of extended simples. We reconcile these two notions by two means. On the one hand we pay closer attention to the physics of our world. On the other hand, we consider what happens when our concept of something—in this case space—contains elements not all of which are realized in anything, but instead key components are realized in different features of the world.

Digital phenotyping will potentially enable earlier detection and prediction of mental illness by monitoring human interaction with and through digital devices. Notwithstanding its promises, it is certain that a person’s digital phenotype will at times be at odds with their first-person testimony of their psychological states. In this paper, we argue that there are features of digital phenotyping in the context of psychiatry which have the potential to exacerbate the tendency to dismiss patients’ testimony and treatment preferences, which can be (...) instances of epistemic injustice. We first explain what epistemic injustice is, and why it is argued to be an extensive problem in health and disability settings. We then explain why epistemic injustice is more likely to apply with even greater force in psychiatric contexts, and especially where digital phenotyping may be involved. Finally, we offer some tentative suggestions of how epistemic injustice can be minimised in digital psychiatry. (shrink)

Francis Ysidro Edgeworth’s unduly neglected monograph New and Old Methods of Ethics (1877) advances a highly sophisticated and mathematized account of social well-being in the utilitarian tradition of his 19th-century contemporaries. This article illustrates how his usage of the ‘calculus of variations’ was combined with findings from empirical psychology and economic theory to construct a consequentialist axiological framework. A conclusion is drawn that Edgeworth is a methodological predecessor to several important methods, ideas, and issues that continue to be discussed in (...) contemporary social well-being studies.

The revival of republicanism was meant to challenge the hegemony of liberalism in contemporary political theory on the grounds that liberals show insufficient concern with institutional protection against political misrule. This article challenges this view by showing how neorepublicanism, particularly on Philip Pettit’s formulation, demands no greater institutional protection than does political liberalism. By identifying neutrality between conceptions of the good as the constraint on institutional requirements that forces neorepublicanism into the liberal framework, the article shows that neutrality is what (...) neorepublicans must jettison to offer a tenable critique of liberalism. Only then can neorepublicans ensure greater protection against misrule by demanding that citizens participate more actively in politics. They can then also criticize liberalism for failing to appreciate the importance of such protection. (shrink)

This chapter discusses ontological commitment to properties, understood as ontological correlates of predicates. We examine the issue in four metaontological settings, beginning with an influential Quinean paradigm on which ontology concerns what there is. We argue that this naturally but not inevitably avoids ontological commitment to properties. Our remaining three settings correspond to the most prominent departures from the Quinean paradigm. Firstly, we enrich the Quinean paradigm with a primitive, non-quantificational notion of existence. Ontology then concerns what exists. We argue (...) that this strengthens the Quinean case against ontological commitment to properties while also newly distinguishing between stronger and weaker forms of nominalism. Secondly, we enrich the Quinean paradigm with the ideology of fundamentality. Ontology then centrally concerns what’s fundamental. We argue that this leaves ontological commitment to properties wide open although Bradleyan regress threatens. Thirdly, we enrich the Quinean paradigm with primitive higher-order quantifiers. Ontology then expands to concern what there higher-order is and what there first-order is. We argue that this naturally but not inevitably incurs ontological commitment to properties. (shrink)

This volume offers a collection of in-depth explorations of pragmatism as a framework for discussions in philosophy of science and metaphysics. Each chapter involves explicit reflection on what it means to be pragmatist, and how to use pragmatism as a guiding framework in addressing topics such as realism, unification, fundamentality, truth, laws, reduction, and more. -/- .

What might be the fundamental psychology of intelligence naturally selected in biological evolution to minimize, prevent, and cure social and personal issues like war, crime, commit suicide, homicide, theft, drug addictions, and so on? How to achieve a higher level of well-being? I found a primary cognitive limiting factor called mind viruses (MV)(more than 3000) which regresses intelligence and well-being and makes the grand delusion: remedies are healthy mind viruses(HMV)(3000). Here, I show the disclosed core of early Buddhist teachings (on (...) learning, training the mind, and behavior on the 8-fold psychological course psychologically 'program' for better (intelligent) decisions. A theoretical 3D graph might represent the state of evolution of intelligence, nature, nurture, X-ultra quantum unique consciousness particle (X-UQUPC), and psychological well-being with the psychological time of a person. To this hypothesis, if the afterlife occurs, the natural selection of vacant zygote/early embryo neurons of the next life and their quality might depend on the finally evolved X-ultra quantum genomic particle of consciousness (X-UQGPC). Therefore, the quality, including the species of the new life and its nurture in the universe/s, depends on the quality of the finally evolved X-UQGPC. Such natural selection of a new nurturing environment for future (promising)life might be uncertain and, therefore, a high risk of finding a life-consciousness in great nature and nurture. However, there may be more mysterious issues to be solved in future research; therefore, the article might not discuss a theory of everything on the central theme. -/- . (shrink)

Suppose some person 'A' sets out to accomplish a difficult, long-term goal such as writing a passable Ph.D. thesis. What should you believe about whether A will succeed? The default answer is that you should believe whatever the total accessible evidence concerning A's abilities, circumstances, capacity for self-discipline, and so forth supports. But could it be that what you should believe depends in part on the relationship you have with A? We argue that it does, in the case where A (...) is yourself. The capacity for "grit" involves a kind of epistemic resilience in the face of evidence suggesting that one might fail, and this makes it rational to respond to the relevant evidence differently when you are the agent in question. We then explore whether similar arguments extend to the case of "believing in" our significant others -- our friends, lovers, family members, colleagues, patients, and students. (shrink)

The paper describes the design of an intelligent tutoring system for teaching Introduction to Computer Science-a compulsory curriculum in Al-Azhar University of Gaza to students who attend the university.

The debate on ideal theory focuses mainly on whether it can provide a long-term target and a metric for assessing the justice of different institutional arrangements in non-ideal theory. Both critics and defenders of ideal theory typically overlook the role it plays in a model of fairness that can restrict the range of permissible arrangements under non-ideal conditions. In this paper, I explain ideal theory’s fairness role and its part in ensuring an institutional structure that benefits everyone in a society. (...) Critics of ideal theory therefore cannot reject it as simply useless. But I consider how they can question the attractiveness of an ideal-theory-based fairness constraint on non-ideal theory.

Perez-Rodriguez and de la Fuente (2017) assume that although human races do not exist in a biological sense (“geneticists and evolutionary biologists generally agree that the division of humans into races/subspecies has no defensible scientific basis,” they exist only as “sociocultural constructions” and because of that maintain an illusory reality, for example, through “racialized” practices in medicine. Agreeing with the main postulates formulated in the article, we believe that the authors treat this problem in a superficial manner and have failed (...) to capture the current state of the field of knowledge in science and the humanities. In our commentary, we want to highlight two main omissions, and to notice three important implications for “a postracial medicine.”. (shrink)

There remains no consensus among social scientists as to how to measure and understand forms of information deprivation such as misinformation. Machine learning and statistical analyses of information deprivation typically contain problematic operationalizations which are too often biased towards epistemic elites' conceptions that can undermine their empirical adequacy. A mature science of information deprivation should include considerable citizen involvement that is sensitive to the value-ladenness of information quality and that doing so may improve the predictive and explanatory power of extant (...) models.

John Rawls thinks republicanism is compatible with his political liberalism. Philip Pettit insists that the two conflict in important ways. In this paper, I make sense of this dispute by employing David Chalmers’s method of elimination to reveal the meaning underlying key terms in Rawls’s political liberalism and Pettit’s republicanism. This procedure of disambiguating terms will show how the two theories defend the same institutional arrangement on the same grounds. The procedure thus vindicates Rawls’s view of the two theories being (...) compatible. The reason for this compatibility is that both theories are politicized—that is, they are constructed to attract the compliance of all reasonable members of a modern, pluralistic society. (shrink)

Trope theory is an increasingly prominent contender in contemporary debates about the existence and nature of properties. But it suffers from ambiguity concerning the nature of a trope. Disambiguation reveals two fundamentally different concepts of a trope: modifier tropes and module tropes. These types of tropes are unequally suited for metaphysical work. Modifier tropes have advantages concerning powers, relations, and fundamental determinables, whereas module tropes have advantages concerning perception, causation, character-grounding, and the ontology of substance. Thus, the choice between modifier (...) tropes and module tropes is significant and divides the advantages of trope theory simpliciter. In addition, each resulting trope theory is unstable: modifier trope theory threatens to collapse into realism and module trope theory threatens to collapse into austere nominalism. This invites reflection on the stability of trope theory in general. (shrink)

This paper explores the view that the vocabulary of metaphysical fundamentality is opaque, using Sider’s theory of structure as a motivating case study throughout. Two conceptions of fundamentality are distinguished, only one of which can explain why the vocabulary of fundamentality is opaque.

In Mengzi 6A4, Gaozi states that “yì 義 (propriety, rightness) is external, not internal.” In 6A5, Meng Jizi says of yì that “...it is on the external, not from the internal.” Their defenses are met with Mengzi’s resistance. What does he perceive and resist in these statements? Focusing on several key passages, I compare six promising interpretations. 6A4 and a relevant part of 2A2 can be rendered comparably sensible under each of the six. However, what Gaozi says in 6A1 clearly (...) is evidence to Mengzi that, of the six views, Gaozi holds three although he does not convey them in his statement. As for Meng Jiz’s defense of his statement, Meng Jizi cites a special occasion where one is required to act one way even though one would feel a different way. Mengzi’s response has been traditionally interpreted as boiling down to a dissenting opinion about empirical psychology, that the agent on that special occasion would in fact feel the same way as they ought to act. But on a more charitable reading, the point Mengzi makes is conceptual: Though the satisfaction of yì may not require that the feeling and the act align perfectly in this case, cases where the alignment obtains are conceptually prior. This not only refutes Meng Jizi’s statement but also enables a more elegant explanation of why the Mengzi rightly has no record of Mengzi affirming that yì is internal. I conclude that 6A5 itself uniquely favors one interpretation, as far as Meng Jizi’s position is concerned: How one feels is irrelevant to whether one satisfies yì. (shrink)

Shame is most frequently defined as the emotion we feel when we fail to live up to standards, norms, or ideals. I argue that this definition is flawed because it cannot explain some of the most paradigmatic features of shame. Agents often respond to shame with violence, but if shame is the painful feeling of failing to live up to an ideal, this response is unintelligible. I offer a new account of shame that can explain the link between shame and (...) violence. On my view, shame arises out of a tension between our identity and our self-conception: those things about which we feel shame are part of our identities, but they are not part of our self-conception. I conclude by arguing that this account of shame is a valuable moral emotion. (shrink)

Recently, mainstream philosophy journals have tended to implement more and more stringent forms of peer review, probably in an attempt to prevent editorial decisions that are based on factors other than quality. Against this trend, we propose that journals should relax their standards of acceptance, as well as be less restrictive about whom is to decide what is admitted into the debate. We start by arguing, partly on the basis of the history of peer review in the journal Mind, that (...) past and current peer review practices attest to partisanship with respect to philosophical approach. Then, we explain that such partisanship conflicts with the standard aims of peer review, and that it is both epistemically and morally problematic. This assessment suggests that, if feasible, journals should treat all available and proposed standards of acceptance in philosophy as epistemically equal, and that philosophical work should be evaluated in terms of the novelty and significance of its contribution to developing thought in ways that are of value. Finally, we show, in a programmatic way, that improving the current situation is feasible, and can be done fairly easily. (shrink)

There is a largely unrecognized ambiguity concerning the nature of a trope. Disambiguation throws into relief two fundamentally different conceptions of a trope and provides two ways to understand and develop each metaphysical theory that put tropes to use. In this paper I consider the relative merits that result from differences concerning a trope’s ability to ground the character of ordinary objects. I argue that on each conception of a trope, there are unique implications and challenges concerning character-grounding.

The goals and tasks of neuroethics formulated by Farahany and Ramos (2020) link epistemological and methodological issues with ethical and social values. The authors refer simultaneously to the social significance and scientific reliability of the BRAIN Initiative. They openly argue that neuroethics should not only examine neuroscientific research in terms of “a rigorous, reproducible, and representative neuroscience research process” as well as “explore the unique nature of the study of the human brain through accurate and representative models of its function (...) and dysfunction”, but also its responsibilities or social consequences. In our commentary, we would like to concentrate on problem selection, which is shortly noticed by Farahany and Ramos, and by BRAIN Initiative’s Neuroethics Report itself. The document raises an important issue related to problem selection, which is strengthening or perpetuating existing prejudices and biases by choosing a research subject: “scientists are prompted to consider how the questions they choose to study in the laboratory might amplify existing biases.” This leads to several further problems: what constitutes bias?; how biases may be embedded in the selection of research programs?; is it possible to conduct completely unbiased research?; who should be a gatekeeper in the case of research that may amplify biases? We try to notice possible answers to these questions in the context of the research on differences (e.g., cognitive, medical, behavioral) between human populations. (shrink)

Recent work has argued that there may be cases where no attitude – including withholding – is rationally permissible. In this paper, I consider two such epistemic dilemmas, John Turri’s Dilemma from Testimony and David Alexander’s Dilemma from Doubt. Turri presents a case where one’s only evidence rules out withholding (without warranting belief or disbelief). Alexander presents a case where higher order doubt means one must withhold judgment over whether withholding judgment is rational. In both cases, the authors conclude that (...) no doxastic attitude is warranted. In this paper, I argue against the possibility of these epistemic dilemmas. I argue that withholding cannot be irrational in either case. But meditating on the dilemmas gives us an important – and overlooked – insight into the nature of rational withholding. First, rational withholding is a function of evidence failing to sufficiently support belief or disbelief. As a result, withholding is not symmetrical to belief and disbelief. Second, there can be two distinct grounds for rational withholding. First, propositional withholding, which arises when our evidence does not support belief or disbelief in p. And second, doxastic withholding, which arises when we cannot determine whether our evidence supports belief or disbelief in p. Accepting two grounds of rational withholding licenses a kind of Weak Permissivism. But this Weak Permissivism should not be troubling to anyone. (shrink)

We characterize, more precisely than before, what Rawls calls the “analytical” method of drawing up a list of basic liberties. This method employs one or more general conditions that, under any just social order whatever, putative entitlements must meet for them to be among the basic liberties encompassed, within some just social order, by Rawls’s first principle of justice (i.e., the liberty principle). We argue that the general conditions that feature in Rawls’s own account of the analytical method, which employ (...) the notion of necessity, are too stringent. They ultimately fail to deliver as basic certain particular liberties that should be encompassed within any fully adequate scheme of liberties. To address this under-generation problem, we provide an amended general condition. This replaces Rawls’s necessity condition with a probabilistic condition and it appeals to the standard liberal prohibition on arbitrary coercion by the state. We defend our new approach both as apt to feature in applications of the analytical method and as adequately grounded in justice as fairness as Rawls articulates the theory’s fundamental ideas.

In this paper I explore Michael Loux’s important distinction between “tropes” and “tropers”. First, I argue that the distinction throws into relief an ambiguity and discrepancy in the literature, revealing two fundamentally different versions of trope theory. Second, I argue that the distinction brings into focus unique challenges facing each of the resulting trope theories, thus calling into question an alleged advantage of trope theory—that by uniquely occupying the middle ground between its rivals, trope theory is able to recover and (...) preserve the insights of these views. Ultimately, the distinction suggests that trope theory is a divided house. (shrink)

It is common to think that we would be morally better people if we never felt envy. Recently, some philosophers have rejected this conclusion by arguing that envy can often be directed toward unfairness or inequality. As such, they conclude that we should not suppress our feelings of envy. I argue, however, that these defenses only show that envy is sometimes morally permissible. In order to show that we would not be better off without envy, we must show how envy (...) is not merely morally permissible, but morally valuable. Here I provide a defense of envy's moral value. I argue that feelings of envy are integral to the value that moral agents place on the goods and talents that they judge to be central to a worthwhile life. (shrink)

Are properties perfectly natural (or not) relative to worlds, or are they perfectly natural (or not) tout court? That is, could there be a property P that is instanti-ated at worlds w1 and w2, and is perfectly natural at w1 but not at w2? Here, we offer an original argument for the non-world-relativity of perfect naturalness. Along the way, we reply to a prima facie compelling argument for the contin-gency of perfect naturalness, based upon the connection between natural prop-erties and (...) laws of nature. (shrink)

It is widely recognized that accurately identifying and classifying competitors is a challenge for many companies and entrepreneurs. Nonetheless, it is a paramount activity which provide valuable insights that affect a wide range of strategic decisions. One of the main challenges in competitor identification lies in the complex nature of the competitive relationships that arise in business envi- ronments. These have been extensively investigate over the years, which lead to a plethora of competition theories and frameworks. Still, the concept of (...) competition remains conceptually complex, as none of these approaches properly formalized their assumptions. In this paper, we address this issue by means of an ontological analysis on the notion of competition in general, and of business competition, in particular, leveraging theories from various fields, including Marketing, Strategic Management, Ecology, Psychology and Cognitive Sciences. Our analysis, the first of its kind in the literature, is grounded on the Unified Foundational Ontology (UFO) and allows us to formally characterize why competition arises, as well as to distinguish between three types of business competitive relationships, namely market-level, firm-level and potential competition.

There are two broad approaches to theorizing about ontological categories. Quineans use first-order quantifiers to generalize over entities of each category, whereas type theorists use quantification on variables of different semantic types to generalize over different categories. Does anything of import turn on the difference between these approaches? If so, are there good reasons to go type-theoretic? I argue for positive answers to both questions concerning the category of propositions. I also discuss two prominent arguments for a Quinean conception of (...) propositions, concerning their role in natural language semantics and apparent quantification over propositions within natural language. It will emerge that even if these arguments are sound, there need be no deep question about Quinean propositions’ true nature, contrary to much recent work on the metaphysics of propositions.

I examine the meaning and merits of a premise in the Exclusion Argument, the causal closure principle that all physical effects have physical causes. I do so by addressing two questions. First, if we grant the other premises, exactly what kind of closure principle is required to make the Exclusion Argument valid? Second, what are the merits of the requisite closure principle? Concerning the first, I argue that the Exclusion Argument requires a strong, “stringently pure” version of closure. The latter (...) employs two qualifications concerning the physical sufficiency and relative proximity of the physical cause required for every physical effect. The second question is addressed in two steps. I begin by challenging the adequacy of the empirical support offered by David Papineau for closure. Then I assess the merits of “level” and “domain” versions of stringently pure closure. I argue that a domain version lacks adequate and non-question-begging support within the context of the Exclusion Argument. And I argue that the level version leads to a puzzling metaphysics of the physical domain. Thus, we have grounds for rejecting the version of closure required for the Exclusion Argument. This means we can resist the Exclusion Argument while avoiding the implausible implications that come with rejecting one of its other premises. That is, because there are grounds to reject causal closure, one can reasonably affirm the non-overdeterminative causal efficacy of conscious mental states while denying that the latter are identical with physical states.

“On the Subject Matter of Phenomenological Psychopathology” provides a framework for the phenomenological study of mental disorders. The framework relies on a distinction between (ontological) existentials and (ontic) modes. Existentials are the categorial structures of human existence, such as intentionality, temporality, selfhood, and affective situatedness. Modes are the particular, concrete phenomena that belong to these categorial structures, with each existential having its own set of modes. In the first section, we articulate this distinction by drawing primarily on the work of (...) Martin Heidegger—especially his study of the ontological structure of affective situatedness (Befindlichkeit) and its particular, ontic modes, which he calls moods (Stimmungen). In the second section, we draw on a study of grief to demonstrate how this framework can be used when conducting phenomenological interviews and analyses. In the concluding section, we explain how this framework can be guide phenomenological studies across a broad range of existential structures. (shrink)
