I explore the view that the imago Dei is essential to us as humans but accidental to us as persons. To image God is to resemble God, and resemblance comes in degrees. This has the straightforward—and perhaps disturbing—implication that we can be more or less human, and possibly cease to be human entirely. Hence, I call it the spectrum view. I argue that the spectrum view is complementary to the Biblical data, helps explain the empirical reality of horrendous evil, and (...) offers an elegant rapprochement between the traditional view of hell and its rivals.

Many philosophers have appealed to the PSR in arguments for a being that exists a se, a being whose explanation is in itself. But what does it mean, exactly, for something to have its explanation ‘in itself’? Contemporary philosophers have said next to nothing about this, relying instead on phrases plucked from the accounts of various historical figures. In this article, I analyse five such accounts – those of Anselm, Aquinas, Descartes, Spinoza, and Leibniz – and argue that none are (...) satisfactory. Should we abandon or restrict the PSR, then? I think that would be hasty, for many reasons. I therefore consider the prospects of explaining everything, including God, given the constraints of certain features of good explanations, and conclude with several observations about future approaches.

Would the existence of extraterrestrial intelligent life conflict in any way with Christian belief? We identify six areas of potential conflict. If there be no conflict in any of these areas—and we argue ultimately there is not—we are confident in declaring that there is no conflict, period. This conclusion underwrites the integrity of theological explorations into the existence of ETI, which has become a topic of increasing interest among theologians in recent years.

I argue that Social Trinitarians can and should conceive of God as a group person. They can by drawing on recent theories of group agency realism that show how groups can be not just agents but persons distinct from their members – albeit, I argue, persons of a different kind. They should because the resultant novel view of the Trinity – that God is three ‘intrinsicist’ persons in one ‘functional’ person – is theologically sound, effectively counters the most trenchant criticisms (...) of Social Trinitarianism, and enjoys independent theological support from the biblical notion of ‘corporate personality’.

The question I wish to explore is this: Does idealism conflict with common sense? Unfortunately, the answer I give may seem like a rather banal one: It depends. What do we mean by ‘idealism’ and ‘common sense?’ I distinguish three main varieties of idealism: absolute idealism, Berkeleyan idealism, and dualistic idealism. After clarifying what is meant by common sense, I consider whether our three idealisms run afoul of it. The first does, but the latter two don’t. I conclude that while (...) Moore’s famous common sense critique is sound against external world skepticism, against Berkeleyan idealism and dualist idealism it is unavailing. (shrink)

Linda Zagzebski’s book on epistemic authority is an impressive and stimulating treatment of an important topic. 1 I admire the way she manages to combine imagination, originality and argumentative control. Her work has the further considerable merit of bringing analytic thinking and abstract theory to bear upon areas of concrete human concern, such as the attitudes one should have towards moral and religious authority. The book is stimulating in a way good philosophy should be -- provoking both disagreement and emulation. (...) I agree with much of what she says, and have been instructed by it, but it will be of more interest and relevance here if I concentrate upon areas of disagreement. Perhaps they are better seen as areas, at least some of them, where her emphases suggest a position that seems to me untenable, but that she may not really intend. In that event, I will be happy to have provoked a clarification or the dispelling of my misunderstanding. My focus will be upon problems in her account of communal authority and autonomy, especially with respect to religious and political authority. Here my worry is that she places too much trust in trust and not enough in what I call selective mistrust. (shrink)

The COVID-19 pandemic revealed numerous weaknesses in pandemic preparedness and response, including underfunding, inadequate surveillance, and inequitable distribution of countermeasures. To overcome these weaknesses for future pandemics, WHO released a zero draft of a pandemic treaty in February, 2023, and subsequently a revised bureau's text in May, 2023. COVID-19 made clear that pandemic prevention, preparedness, and response reflect choices and value judgements. These decisions are therefore not a purely scientific or technical exercise, but are fundamentally grounded in ethics. The latest (...) treaty draft reflects these ethical considerations by including a section entitled Guiding Principles and Approaches. Most of these principles are ethical—they establish core values that undergird the treaty. Unfortunately, the treaty draft's set of principles are numerous, overlapping, and show inadequate coherence and consistency. We propose two improvements to this section of the draft pandemic treaty. First, key guiding ethical principles should be clearer and more precise than they currently are. Second, the link between ethical principles and policy implementation should be clearly established and define boundaries on acceptable interpretation, ensuring that signatories abide by these principles.

This paper replies to a commentary by John-Stewart Gordon on our paper, “The Moral Standing of Social Robots: Untapped Insights from Africa.” In the original paper, we set forth an African relational view of personhood and show its implica- tions for the moral standing of social robots. This reply clarifies our position and answers three objections. The objections concern (1) the ethical significance of intelligence, (2) the meaning of ‘pro-social,’ and (3) the justification for prioritizing humans over pro-social robots.

This paper argues for global sharing of COVID‐19 treatments during the COVID‐19 pandemic and beyond based on principles of global solidarity. It starts by distinguishing two types of COVID‐19 treatments and models sharing strategies for each in small‐group scenarios, contrasting groups that are solidaristic with those composed of self‐interest maximizers to show the appeal of solidaristic reasoning. It then extends the analysis, arguing that a similar logic should apply within and between nations. To further elaborate global solidarity, the paper distinguishes (...) morally voluntary, sliding‐scale, and mandatory versions. It argues for an all‐hands‐on‐deck approach and gives examples to illustrate. The paper concludes that during the COVID‐19 crisis, global solidarity is a core value, and global sharing of COVID‐19 treatments should be considered a duty of justice, not of charity. (shrink)

What are we to make of the cultural nonconformity of hardcore/punks? Is there any ethical value in the pursuit of cultural nonconformity? Distinct moral justifications can be teased from the lyrics of the hardcore/punk bands that we have grown up with and still love. The best explanation of what makes cultural nonconformity morally valuable, we believe, comes from John Stuart Mill: that it opens up new cultural space to oneself and to others, permitting "new and original experiments of living.".

In 2020, an international team of intercultural philosophers and African linguists created a multilinguistic game named Adinkra. This name refers to a medieval rooted symbolic language in Ghana that is actively used by the Akan and especially the Asante among them to communicate indirectly. The Akan is both the meta-ethnic name of the largest Ghanaian cultural-linguistic group of which the Asante is an Akan cultural subgroup and of a Central Tano language of which Asante-Twi is a dialect. The Adinkra symbols, (...) which have permeated Akan life and the arts, can be found e.g. on Asante royal staffs and gold weights. They are also loosely connected to Akan proverbs. The game Adinkra aims to enhance its players’ intercultural communicative, and moral philosophical understanding by matching Adinkra symbols with Akan proverbs. It was created for educational and therapeutical purposes. This article focusses on the rules, the making of Adinkra, its aims and objectives. The objective of this article is twofold. First, it focusses on the game itself. It elaborates on what its rules are and the content of the game. It also focusses on how playing the multilinguistic game, Adinkra can enhance intercultural understanding and communication. It, furthermore, concentrates on the results of a pilot reception study of this game in the Netherlands among intercultural groups of players. This study has proven that the Adinkra game stimulates creative thinking, engagement in dialogue and reflective ethical thinking. For this reason, the authors believe that it has a lot to contribute to intercultural educational programs with a focus on intercultural communication, philosophy and arts in both Africa and the global North. Finally, a section is devoted to the question of how the Adinkra game was developed and methodologically grounded in Gadamer’s playful hermeneutics, and the theories of the Wheel of the Intercultural Art of living and (African) Indigenous Religions. Secondly, the article focusses on the game’s oral-literary storytelling context and Akan moral ideas. It then throws the searchlight on the creative, therapeutic value and its potential to serve as a ‘cultural detox’. The authors and game makers think that being introduced to an African communitarian ethos hidden in the Adinkra symbols and Akan proverbs can help its players to develop a critical eye for the highly individualistic ethos of Western culture that, among others, is promoted by neoliberal thinking and praxis. The word praxis is used by the authors in the meaning found in educational contexts. Adinkra’s players are stimulated to reflect upon a different moral idea, which can change their mindset and put them into action to contribute to social awareness and societal change. (shrink)

Visual imagery is a form of sensory imagination, involving subjective experiences typically described as similar to perception, but which occur in the absence of corresponding external stimuli. We used the Activation Likelihood Estimation algorithm (ALE) to identify regions consistently activated by visual imagery across 40 neuroimaging studies, the first such meta-analysis. We also employed a recently developed multi-modal parcellation of the human brain to attribute stereotactic co-ordinates to one of 180 anatomical regions, the first time this approach has been combined (...) with the ALE algorithm. We identified a total 634 foci, based on measurements from 464 participants. Our overall comparison identified activation in the superior parietal lobule, particularly in the left hemisphere, consistent with the proposed ‘top-down’ role for this brain region in imagery. Inferior premotor areas and the inferior frontal sulcus were reliably activated, a finding consistent with the prominent semantic demands made by many visual imagery tasks. We observed bilateral activation in several areas associated with the integration of eye movements and visual information, including the supplementary and cingulate eye fields (SCEFs) and the frontal eye fields (FEFs), suggesting that enactive processes are important in visual imagery. V1 was typically activated during visual imagery, even when participants have their eyes closed, consistent with influential depictive theories of visual imagery. Temporal lobe activation was restricted to area PH and regions of the fusiform gyrus, adjacent to the fusiform face complex (FFC). These results provide a secure foundation for future work to characterise in greater detail the functional contributions of specific areas to visual imagery. (shrink)

A graph-theoretic account of logics is explored based on the general notion of m-graph (that is, a graph where each edge can have a finite sequence of nodes as source). Signatures, interpretation structures and deduction systems are seen as m-graphs. After defining a category freely generated by a m-graph, formulas and expressions in general can be seen as morphisms. Moreover, derivations involving rule instantiation are also morphisms. Soundness and completeness theorems are proved. As a consequence of the generality of the (...) approach our results apply to very different logics encompassing, among others, substructural logics as well as logics with nondeterministic semantics, and subsume all logics endowed with an algebraic semantics.

Background If trials of therapeutic interventions are to serve society's interests, they must be of high methodological quality and must satisfy moral commitments to human subjects. The authors set out to develop a clinical - trials compendium in which standards for the ethical treatment of human subjects are integrated with standards for research methods. Methods The authors rank-ordered the world's nations and chose the 31 with >700 active trials as of 24 July 2008. Governmental and other authoritative entities of the (...) 31 countries were searched, and 1004 English-language documents containing ethical and/or methodological standards for clinical trials were identified. The authors extracted standards from 144 of those: 50 designated as ‘core’, 39 addressing trials of invasive procedures and a 5% sample of the remainder. As the integrating framework for the standards we developed a coherent taxonomy encompassing all elements of a trial's stages. Findings Review of the 144 documents yielded nearly 15 000 discrete standards. After duplicates were removed, 5903 substantive standards remained, distributed in the taxonomy as follows: initiation, 1401 standards, 8 divisions; design, 1869 standards, 16 divisions; conduct, 1473 standards, 8 divisions; analysing and reporting results, 997 standards, four divisions; and post-trial standards, 168 standards, 5 divisions. Conclusions The overwhelming number of source documents and standards uncovered in this study was not anticipated beforehand and confirms the extraordinary complexity of the clinical trials enterprise. This taxonomy of multinational ethical and methodological standards may help trialists and overseers improve the quality of clinical trials, particularly given the globalisation of clinical research.

Recent research has relied on trolley-type sacrificial moral dilemmas to study utilitarian versus nonutili- tarian modes of moral decision-making. This research has generated important insights into people’s attitudes toward instrumental harm—that is, the sacrifice of an individual to save a greater number. But this approach also has serious limitations. Most notably, it ignores the positive, altruistic core of utilitarianism, which is characterized by impartial concern for the well-being of everyone, whether near or far. Here, we develop, refine, and validate a (...) new scale—the Oxford Utilitarianism Scale—to dissociate individual differences in the ‘negative’ (permissive attitude toward instrumental harm) and ‘positive’ (impartial concern for the greater good) dimensions of utilitarian thinking as manifested in the general population. We show that these are two independent dimensions of proto-utilitarian tendencies in the lay population, each exhibiting a distinct psychological profile. Empathic concern, identification with the whole of humanity, and concern for future generations were positively associated with impartial beneficence but negatively associated with instrumental harm; and although instrumental harm was associated with subclinical psychopathy, impartial beneficence was associated with higher religiosity. Importantly, although these two dimensions were independent in the lay population, they were closely associated in a sample of moral philosophers. Acknowledging this dissociation between the instrumental harm and impartial beneficence components of utilitarian thinking in ordinary people can clarify existing debates about the nature of moral psychology and its relation to moral philosophy as well as generate fruitful avenues for further research.

The New Evil Demon Problem is supposed to show that straightforward versions of reliabilism are false: reliability is not necessary for justification after all. I argue that it does no such thing. The reliabilist can count a number of beliefs as justified even in demon worlds, others as unjustified but having positive epistemic status nonetheless. The remaining beliefs---primarily perceptual beliefs---are not, on further reflection, intuitively justified after all. The reliabilist is right to count these beliefs as unjustified in demon worlds, (...) and it is a challenge for the internalist to be able to do so as well. (shrink)

Euclid’s Elements inspired a number of foundationalist accounts of mathematics, which dominated the epistemology of the discipline for many centuries in the West. Yet surprisingly little has been written by recent philosophers about this conception of mathematical knowledge. The great exception is Imre Lakatos, whose characterisation of the Euclidean Programme in the philosophy of mathematics counts as one of his central contributions. In this essay, we examine Lakatos’s account of the Euclidean Programme with a critical eye, and suggest an alternative (...) picture which builds on his work, but differs in a number of important respects.

In mathematics, the deductive method reigns. Without proof, a claim remains unsolved, a mere conjecture, not something that can be simply assumed; when a proof is found, the problem is solved, it turns into a “result,” something that can be relied on. So mathematicians think. But is there more to mathematical justification than proof? -/- The answer is an emphatic yes, as I explain in this article. I argue that non-deductive justification is in fact pervasive in mathematics, and that it (...) is in good epistemic standing. (shrink)

Whenever science returns a confident and univocal answer to a question, Trumping Naturalism enjoins us to accept it. The majority of contemporary philosophers are sympathetic to this sort of position. Indeed, several have endorsed it or something very close to it. Arguments for Trumping Naturalism, however, are scant, the principal one being the Track Record Argument. The argument is based on the fact that in cases of conflict, science has a better track record than non-scientific forms of inquiry such as (...) philosophy. My chapter investigates this argument. I enumerate and assess several objections to the argument, from footling objections to stronger ones. My conclusion is that the Track Record Argument is not as strong as imagined. (shrink)

The revival of the philosophy of mathematics in the 60s following its post-1931 slump left us with two conflicting positions on arithmetic’s ontological relationship to set theory. W.V. Quine’s view, presented in 'Word and Object' (1960), was that numbers are sets. The opposing view was advanced in another milestone of twentieth-century philosophy of mathematics, Paul Benacerraf’s 'What Numbers Could Not Be' (1965): one of the things numbers could not be, it explained, was sets; the other thing numbers could not be, (...) even more dramatically, was objects. Curiously, although Benacerraf’s article appeared in the heyday of Quine’s influence, it declined to engage the Quinean position squarely, even seemed to think it was not its business to do so. Despite that, in my experience, most philosophers believe that Benacerraf’s article put paid to the reductionist view that numbers are sets (though perhaps not the view that numbers are objects). My chapter will attempt to overturn this orthodoxy. (shrink)

Como veremos, tais perdas estão, em verdade, diretamente ligadas ao colapso do mundo (...) antigo e ao derradeiro golpe proferido por Justiniano contra a filosofia helênica pagã. (shrink)

This paper focuses on invasive therapeutic procedures, defined as procedures requiring the introduction of hands, instruments, or devices into the body via incisions or punctures of the skin or mucous membranes performed with the intent of changing the natural history of a human disease or condition for the better. Ethical and methodological concerns have been expressed about studies designed to evaluate the effects of invasive therapeutic procedures. Can such studies meet the same standards demanded of those, for example, evaluating pharmaceutical (...) agents? This paper describes a research project aimed at examining the interplay and sometimes apparent conflict between ethical standards for human research and standards for methodological rigor in trials of invasive procedures. The paper discusses how the authors plan to develop a set of consensus standards that, if met, would result in substantial and much-needed improvements in the methodological and ethical quality of such trials.

A key source of support for the view that challenging people’s beliefs about free will may undermine moral behavior is two classic studies by Vohs and Schooler (2008). These authors reported that exposure to certain prompts suggesting that free will is an illusion increased cheating behavior. In the present paper, we report several attempts to replicate this influential and widely cited work. Over a series of five studies (sample sizes of N = 162, N = 283, N = 268, N (...) = 804, N = 982) (four preregistered) we tested the relationship between (1) anti-free-will prompts and free will beliefs and (2) free will beliefs and immoral behavior. Our primary task was to closely replicate the findings from Vohs and Schooler (2008) using the same or highly similar manipulations and measurements as the ones used in their original studies. Our efforts were largely unsuccessful. We suggest that manipulating free will beliefs in a robust way is more difficult than has been implied by prior work, and that the proposed link with immoral behavior may not be as consistent as previous work suggests.

This short article discusses the fact that the word ‘ancestor’ features in certain arguments that a) are apparently logically valid, b) contain infinitely many premises, and c) are such that none of their finite sub-arguments are logically valid. The article's aim is to motivate, within its brief compass, the study of infinitary logics.

Recent research has begun treating the perennial philosophical question, “what makes a person the same over time?” as an empirical question. A long tradition in philosophy holds that psychological continuity and connectedness of memories are at the heart of personal identity. More recent experimental work, following Strohminger & Nichols (2014), has suggested that persistence of moral character, more than memories, is perceived as essential for personal identity. While there is a growing body of evidence supporting these findings, a critique by (...) Starmans & Bloom (2018) suggests that this research program conflates personal identity with mere similarity. To address this criticism, we explore how loss of someone’s morality or memories influence perceptions of identity change, and perceptions of moral duties towards the target of the change. We present participants with a classic ‘body switch’ thought experiment and after assessing perceptions of identity persistence, we present a moral dilemma, asking participants to imagine that one of the patients must die (Study 1) or be left alone in a care home for the rest of their life (Study 2). Our results highlight the importance of the continuity of moral character, suggesting lay intuitions are tracking (something like) personal identity, not just mere similarity. (shrink)

It is not a particularly hard thing to want or seek explanations. In fact, explanations seem to be a large and natural part of our cognitive lives. Children ask why and how questions very early in development and seem genuinely to want some sort of answer, despite our often being poorly equipped to provide them at the appropriate level of sophistication and detail. We seek and receive explanations in every sphere of our adult lives, whether it be to understand why (...) a friendship has foundered, why a car will not start, or why ice expands when it freezes. Moreover, correctly or incorrectly, most of the time we think we know when we have or have not received a good explanation. There is a sense both that a given, successful explanation satisfies a cognitive need, and that a questionable or dubious explanation does not. There are also compelling intuitions about what make good explanations in terms of their form, that is, a sense of when they are structured correctly. (shrink)

A focussed issue of The Reasoner on the topic of 'Infinitary Reasoning'. Owen Griffiths and A.C. Paseau were the guest editors.

Many biologists and philosophers have worried that importing models of reasoning from the physical sciences obscures our understanding of reasoning in the life sciences. In this paper we discuss one example that partially validates this concern: part-whole reductive explanations. Biology and physics tend to incorporate different models of temporality in part-whole reductive explanations. This results from differential emphases on compositional and causal facets of reductive explanations, which have not been distinguished reliably in prior philosophical analyses. Keeping these two facets distinct (...) facilitates the identifi cation of two further aspects of reductive explanation: intrinsicality and fundamentality. Our account provides resources for discriminating between different types of reductive explanation and suggests a new approach to comprehending similarities and differences in the explanatory reasoning found in biology and physics.

ABSTRACT Self-Interest and Public Interest in Western Politics showed that the public, politicians, and bureaucrats are often public spirited. But this does not invalidate public-choice theory. Public-choice theory is an ideal type, not a claim that self-interest explains all political behavior. Instead, public-choice theory is useful in creating rules and institutions that guard against the worst case, which would be universal self-interestedness in politics. In contrast, the public-interest hypothesis is neither a comprehensive explanation of political behavior nor a sound basis (...) for institutional design. (shrink)

A brief article introducing *One True Logic*. The book argues that there is one correct foundational logic and that it is highly infinitary.

A graph-theoretic account of fibring of logics is developed, capitalizing on the interleaving characteristics of fibring at the linguistic, semantic and proof levels. Fibring of two signatures is seen as a multi-graph (m-graph) where the nodes and the m-edges include the sorts and the constructors of the signatures at hand. Fibring of two models is a multi-graph (m-graph) where the nodes and the m-edges are the values and the operations in the models, respectively. Fibring of two deductive systems is an (...) m-graph whose nodes are language expressions and the m-edges represent the inference rules of the two original systems. The sobriety of the approach is confirmed by proving that all the fibring notions are universal constructions. This graph-theoretic view is general enough to accommodate very different fibrings of propositional based logics encompassing logics with non-deterministic semantics, logics with an algebraic semantics, logics with partial semantics and substructural logics, among others. Soundness and weak completeness are proved to be preserved under very general conditions. Strong completeness is also shown to be preserved under tighter conditions. In this setting, the collapsing problem appearing in several combinations of logic systems can be avoided. (shrink)

Is the societal-level of analysis sufficient today to understand the values of those in the global workforce? Or are individual-level analyses more appropriate for assessing the influence of values on ethical behaviors across country workforces? Using multi-level analyses for a 48-society sample, we test the utility of both the societal-level and individual-level dimensions of collectivism and individualism values for predicting ethical behaviors of business professionals. Our values-based behavioral analysis indicates that values at the individual-level make a more significant contribution to (...) explaining variance in ethical behaviors than do values at the societal-level. Implicitly, our findings question the soundness of using societal-level values measures. Implications for international business research are discussed. (shrink)

O valor nutritivo do leite de ovelha é superior quando comparado aos leites caprino e bovino, apresentando maior teor proteico, lipídico, minerais e vitaminas. Os humanos evoluíram em estreito contato com a natureza, sendo o leite a primeira fonte de alimento desta espécie ao nascer. Durante milhares de anos, o leite rico em nutrientes, como fonte de alimento, era unicamente materno e só veio a ser consumido pelo homem após idade de amamentação com a domesticação dos animais, primeiramente às ovelhas (...) e as cabras há aproximadamente 13 mil anos, seguido da domesticação das vacas quatro mil anos depois. Desde então o leite tornou-se um alimento indispensável para o homem. O valor nutritivo do leite de ovelha é superior quando comparado aos leites caprino e bovino, apresentando maior teor proteico, lipídico, minerais e vitaminas essenciais para a saúde humana. Este leite apresenta três vezes mais proteínas em relação ao leite de cabra e de vaca, sendo aquelas consideradas proteínas de alto valor biológico contribuindo para uma melhor digestibilidade. Outra característica é a conformação estrutural e a quantidade de micelas de caseína e suas subunidades, que são assim como o leite caprino, menores que as do leite bovino, proporcionando menor sensibilização às pessoas alérgicas. Estudos sugerem que o leite de ovelha pode ser considerado o substituto ideal do leite bovino para pessoas alérgicas ao leite bovino devido ao elevado teor dos principais componentes do leite e minerais. Entretanto, foi verificado que anticorpos IgE de pessoas alérgicas reconhecem as αS1-caseína, αS2-caseína e β-caseína de leite ovino e caprino, mas caseínas do leite bovino são raramente ou não reconhecidas. Além disso, os polimorfismos genéticos das proteínas do leite estão associados com os parâmetros quantitativos e qualitativos e desempenham um papel importante na indução de diferentes graus de reação alérgica. A coloração do leite de ovelha é intensamente branca e homogênea, o que o difere do leite de vaca, pois essa característica está associada à ausência de β-caroteno pigmento precursor do retinol (vitamina A) impedindo que o leite tenha coloração amarelada como no caso do leite bovino. No leite ovino, o β-caroteno apresenta-se na forma convertida da vitamina A que não possui coloração amarelada e essa característica possibilita a produção de diferentes variedades de queijo. A caseína no leite de ovelha compõe 80% do total de proteínas do leite dos ruminantes, enquanto que está presente em 50% da composição proteica do leite equino e em menor porcentagem no leite humano. A caseína do leite de ruminantes difere com relação às características de tamanho, hidratação e mineralização. As micelas de caseína do leite de ovelha possuem maior mineralização e menor hidratação, sendo mais estáveis ao aquecimento quando comparadas à micela de caseína do leite de vaca. Outra importante característica refere-se à conformação molecular e sequencial de aminoácidos com impacto sobre sua digestibilidade, qualidade nutricional e termoestabilidade proteica. As proteínas do leite de ovelha consistem em elevada quantidade de caseínas (resistente ao calor) e proteínas do soro (sensível ao calor) responsáveis pela textura e viscosidade de iogurtes. Tecnologicamente, elas têm propriedades únicas que permitem a fácil conversão do leite em iogurte e queijos, não sendo necessária a adição de sólidos na produção do iogurte, como leite em pó, ou concentração dos sólidos do leite por tecnologia de membrana. Estudos com variantes da caseína do leite ovino representam uma abordagem eficaz para identificar a associação de características de importância econômica e melhorar raças para a produção de proteína do leite específica. As características da caseína no leite de ovelha são particularmente interessantes devido ao número elevado de polimorfismo, alterando a expressão de genes e influenciando o processamento de queijos. Em adição, enzimas presente no leite de ovelha possui atividade proteolítica e lipolítica (quebra de proteínas e lipídios). Elas auxiliam na maturação de queijos - resultando em compostos de aroma e sabor típicos, tornando-os únicos em suas características. O sabor e o aroma do leite de ovelha são suaves e adocicados além de possuir uma textura cremosa devido aos pequenos glóbulos de gordura que apresentam tamanhos menores que 3,5 µm. Esta peculiaridade no tamanho dos glóbulos gordurosos do leite ovino propicia que esse seja digerido mais facilmente. O leite ovino apresenta também altas concentrações de ácidos graxos poli-insaturados com benefícios à saúde como isômeros de ácido linoleico conjugado (CLA) presentes em maior concentração nesta matriz comparado ao leite bovino que são o cis-9 trans-11 e o trans-10 cis-12, responsáveis por ações anticarcinogênica, antiaterogênico e antiobesidade. Ainda com relação aos lipídios do leite de ovelha, as lipases têm um papel importante na produção de leite na glândula mamária. As lipases naturais do leite catalisam e hidrolisam os triglicerídeos, produzindo ácidos graxos livres (AGL). A atividade das lipases, em leite ovino, é cerca de um décimo das do leite bovino. Além disso, o padrão de hidrólise da gordura de leite por ovinos apresenta maior taxa em relação aos triglicerídeos - contendo ácidos graxos de cadeia média em relação aos ácidos graxos de cadeia longa. Os níveis de AGL em queijos de leite ovino são o resultado do processo lipolítico que ocorre durante o período de maturação. Alguns produtos lácteos derivados usando como matéria-prima o leite de ovelha - como iogurte grego e queijos - foram descritos como possuindo peptídeos inibidores da enzima conversora da angiotensina (ECA), sendo a maioria derivada da subunidade β-caseína. Também, alguns peptídeos derivados da κ-caseína, resultante da hidrólise de leite ovino pela pepsina, tripsina e quimotripsina, exercem atividade antioxidante. Em queijos tradicionais derivados de ovelha, como o Scamorza, foram verificados diversos peptídeos com ação inibidora da ECA e ação antibacteriana. Nesse contexto, o leite de ovelha é uma rica fonte de nutrientes e seu principal uso é na produção de queijos devido ao elevado conteúdo de extrato seco total, que contribui com alto rendimento da massa. Todavia, esta matéria-prima permanece inexplorada pela indústria de laticínios com uma visão de alimento funcional, visto que o leite e seus derivados são reconhecidamente ótimos carreadores de fibras prebióticas e bactérias probióticas - que trazem benefícios ao consumidor favorecendo saúde e bem-estar. Nesse contexto, o leite de ovelha apresenta-se como um alimento de grande potencial e uma valiosa alternativa para a indústria de laticínios - que pode aumentar a diversidade de produtos oferecidos ao consumidor.

ABSTRACT Objectives There is little research on moral uncertainties and distress of palliative and hospice care providers (PHCPs) working in jurisdictions anticipating legalising voluntary assisted dying (VAD). This study examines the perception and anticipated concerns of PHCPs in providing VAD in the State of Queensland, Australia prior to legalisation of the practice in 2021. The findings help inform strategies to facilitate training and support the health and well-being of healthcare workers involved in VAD. Design The study used a qualitative approach (...) to examine and analyse the perception and anticipated concerns of PHCPs regarding challenges of providing assisted dying in Queensland. Fourteen PHCPs were recruited using a purposive sampling strategy to obtain a broad representation of perspectives including work roles, geographical locations and workplace characteristics. Data were collected via one in-depth interview per participant. The transcripts were coded for patterns and themes using an inductive analysis approach following the tradition of Grounded Theory. Setting The study was conducted in hospital, hospice, community and residential aged care settings in Queensland, Australia. These included public and private facilities, secular and faith-based facilities, and regional/rural and urban facilities. Participants Interviews were conducted with fourteen PHCPs: 10 nurses and 4 physicians; 11 female and 3 male. The median number of years of palliative care practice was 17, ranging from 2 to 36 years. For inclusion, participants had to be practising palliative and hospice care providers. Results PHCPs are divided on whether VAD should be considered part of palliative care. Expectations of moral distress and uncertainty about practising VAD were identified in five areas: handling requests, assessing patient capacity, arranging patient transfers and logistical issues, managing unsuccessful attempts, and dealing with team conflicts and stigma. Conclusions The possibility of having to practise VAD causes moral distress and uncertainty for some PHCPs. Procedural clarity can address some uncertainties; moral and psychological distress, however, remains a source of tension that needs support to ensure ongoing care of both patients and PHCPs. The introduction of VAD post-legalisation may present an occasion for further moral education and development of PHCPs. (shrink)

In temporal binding, the temporal interval between one event and another, occurring some time later, is subjectively compressed. We discuss two ways in which temporal binding has been conceptualized. In studies showing temporal binding between a voluntary action and its causal consequences, such binding is typically interpreted as providing a measure of an implicit or pre-reflective “sense of agency”. However, temporal binding has also been observed in contexts not involving voluntary action, but only the passive observation of a cause-effect sequence. (...) In those contexts, it has been interpreted as a top-down effect on perception reflecting a belief in causality. These two views need not be in conflict with one another, if one thinks of them as concerning two separate mechanisms through which temporal binding can occur. In this paper, we explore an alternative possibility: that there is a unitary way of explaining temporal binding both within and outside the context of voluntary action as a top-down effect on perception reflecting a belief in causality. Any such explanation needs to account for ways in which agency, and factors connected with agency, have been shown to affect the strength of temporal binding. We show that principles of causal inference and causal selection already familiar from the literature on causal learning have the potential to explain why the strength of people’s causal beliefs can be affected by the extent to which they are themselves actively involved in bringing about events, thus in turn affecting binding.

The way we farm, the kinds of backyards and landscapes we favor, and the way we control patterns of development are creating an invisible crisis through their affects upon soil ecology. The invisibility of soil ecosystems, the seemingly alien properties of the organisms that inhabit them, and the specialized knowledge required to understand them create obstacles to moral concern for these fountains of life. Our treatment of soils has reached the point of crisis. Obstacles to moral thinking about soils might (...) be overcome by supplying the moral imagination with a deeper understanding of our own biological identity as ecosystems analogous in organization and functions to soil ecosystems. Not only have microbes created the conditions necessary for human life, but they have shaped our evolutionary history and helped constitute the human genome. Our biological identity encompasses communities of microbes, such that humans (and all organisms) are most properly understood as ecosystems. For this reason, moral concern for humans implies moral concern for ecosystems. (shrink)

A self-fulfilling prophecy in neuroprognostication occurs when a patient in coma is predicted to have a poor outcome, and life-sustaining treatment is withdrawn on the basis of that prediction, thus directly bringing about a poor outcome for that patient. In contrast to the predominant emphasis in the bioethics literature, we look beyond the moral issues raised by the possibility that an erroneous prediction might lead to the death of a patient who otherwise would have lived. Instead, we focus on the (...) problematic epistemic consequences of neuroprognostic SFPs in settings where research and practice intersect. When this sort of SFP occurs, the problem is that physicians and researchers are never in a position to notice whether their original prognosis was correct or incorrect, since the patient dies anyway. Thus, SFPs keep us from discerning false positives from true positives, inhibiting proper assessment of novel prognostic tests. This epistemic problem of SFPs thus impedes learning, but ethical obligations of patient care make it difficult to avoid SFPs. We then show how the impediment to catching false positive indicators of poor outcome distorts research on novel techniques for neuroprognostication, allowing biases to persist in prognostic tests. We finally highlight a particular risk that a precautionary bias towards early withdrawal of life-sustaining treatment may be amplified. We conclude with guidelines about how researchers can mitigate the epistemic problems of SFPs, to achieve more responsible innovation of neuroprognostication for patients in coma. (shrink)

In this paper, we intend to promote an analysis of the use of the artificial language Heptapod B in Story of Your Life written by Ted Chiang and in its filmic adaptation, Arrival, written by Eric Heisserer and directed by Denis Villeneuve in relation to the authors’ views on the metaphysics of time. In both literary and filmic texts, the glossopoeia is used as a plot device upon which the alien race’s time perception is constructed and explicated in connexion with (...) the strong metaphor provided by Fermat’s principle of least time. Throughout the article, we discuss these hybrid interfaces of literature, cinema and science, researching the stories’ specific diegeses, the writers’ own elicitations as well as various texts on the Philosophy of time. The result consists of a comprehensive exegesis of the problematics generated by the narratives and an extensive philosophical debate on the subject. (shrink)

The political distinction between left and right remains ideologically muddled. This was not always so, but an immediate return to the pristine usage is impractical. Putting a theory of social liberty to one side, this essay defends the interpretation of left-wing as personal-choice and right-wing as property-choice. This allows an axis that is north/choice (or state-free) and south/control (or state-ruled). This Political Compass clarifies matters without being tendentious or too complicated. It shows that what is called ‘libertarianism’ is north-wing. A (...) quiz gives the reader’s Political Compass reading. (shrink)

Achieving space situational awareness requires, at a minimum, the identification, characterization, and tracking of space objects. Leveraging the resultant space object data for purposes such as hostile threat assessment, object identification, and conjunction assessment presents major challenges. This is in part because in characterizing space objects we reference a variety of identifiers, components, subsystems, capabilities, vulnerabilities, origins, missions, orbital elements, patterns of life, operational processes, operational statuses, and so forth, which tend to be defined in highly heterogeneous and sometimes inconsistent (...) ways. The Space Domain Ontologies are designed to provide a consensus-based realist framework for formulating such characterizations in a way that is both consistent and computable. Space object data are aligned with classes and relations in a suite of ontologies built around the existing Space Object Ontology. They are stored in a dynamically updated Resource Description Framework triple store, which can be queried to support space situational awareness and the needs of spacecraft operators and analysts. This paper provides an overview of the Space Domain Ontologies and their development and use. It presents the motivation for and advantages of the Space Domain Ontologies, including the benefits they provide for enhancing and maintaining long-term space situational awareness. (shrink)

Along with offering an historically-oriented interpretive reconstruction of the syntax of PM ( rst ed.), I argue for a certain understanding of its use of propositional function abstracts formed by placing a circum ex on a variable. I argue that this notation is used in PM only when de nitions are stated schematically in the metalanguage, and in argument-position when higher-type variables are involved. My aim throughout is to explain how the usage of function abstracts as “terms” (loosely speaking) is (...) not inconsistent with a philosophy of types that does not think of propositional functions as mind- and language-independent objects, and adopts a nominalist/substitutional semantics instead. I contrast PM’s approach here both to function abstraction found in the typed λ-calculus, and also to Frege’s notation for functions of various levels that forgoes abstracts altogether, between which it is a kind of intermediary.

Biological ontologies are used to organize, curate, and interpret the vast quantities of data arising from biological experiments. While this works well when using a single ontology, integrating multiple ontologies can be problematic, as they are developed independently, which can lead to incompatibilities. The Open Biological and Biomedical Ontologies Foundry was created to address this by facilitating the development, harmonization, application, and sharing of ontologies, guided by a set of overarching principles. One challenge in reaching these goals was that the (...) OBO principles were not originally encoded in a precise fashion, and interpretation was subjective. Here we show how we have addressed this by formally encoding the OBO principles as operational rules and implementing a suite of automated validation checks and a dashboard for objectively evaluating each ontology’s compliance with each principle. This entailed a substantial effort to curate metadata across all ontologies and to coordinate with individual stakeholders. We have applied these checks across the full OBO suite of ontologies, revealing areas where individual ontologies require changes to conform to our principles. Our work demonstrates how a sizable federated community can be organized and evaluated on objective criteria that help improve overall quality and interoperability, which is vital for the sustenance of the OBO project and towards the overall goals of making data FAIR.

What is the primary function of consciousness in the nervous system? The answer to this question remains enigmatic, not so much because of a lack of relevant data, but because of the lack of a conceptual framework with which to interpret the data. To this end, we have developed Passive Frame Theory, an internally coherent framework that, from an action-based perspective, synthesizes empirically supported hypotheses from diverse fields of investigation. The theory proposes that the primary function of consciousness is well-circumscribed, (...) serving the 'somatic nervous system[. For this system, consciousness serves as a frame that constrains and directs skeletal muscle output, thereby yielding adaptive behavior. The mechanism by which consciousness achieves this is more counterintuitive, passive, and “low level” than the kinds of functions that theorists have previously attributed to consciousness. Passive frame theory begins to illuminate (a) what consciousness contributes to nervous function, (b) how consciousness achieves this function, and (c) the neuroanatomical substrates of conscious processes. Our untraditional, action-based perspective focuses on olfaction instead of on vision and is 'descriptive' (describing the products of nature as they evolved to be) rather than 'normative' (construing processes in terms of how they should function). Passive frame theory begins to isolate the neuroanatomical, cognitive-mechanistic, and representational (e.g., conscious contents) processes associated with consciousness. (shrink)
