This paper reviews development research and policies on freshwater fish in South and Southeast Asia. We conduct a systematic review of academic literature from three major science-based policy institutions to analyze development research and policies that have accompanied the ongoing transition from freshwater capture fisheries to aquaculture in the region. Using a ‘food fish system’ framework allows for the identification and systematic comparison of assumptions underpinning dominant development policies. We analyze the interrelations between the production, provisioning, and consumption of wild (...) and farmed fish and demonstrate a shift toward food fish systems thinking in the sampled literature. We discuss gaps and weaknesses in the literature, as identified through the application of the food fish systems framework and present an agenda for future research aimed at securing the potential of fish as food.

In Racial Prescriptions, Jonathan Xavier Inda offers a critical and timely analysis of the making of BiDil, the first drug that was marketed exclusively to African Americans. Sibille Merz speaks to him about the re-articulation of racial politics under neoliberalism, the legacies of scientific racism and the molecularization of biopolitics in the genomic age.
The Statesman is a difficult and puzzling Platonic dialogue. In A Stranger's Knowledge Marquez argues that Plato abandons here the classic idea, prominent in the Republic, that the philosopher, qua philosopher, is qualified to rule. Instead, the dialogue presents the statesman as different from the philosopher, the possessor of a specialist expertise that cannot be reduced to philosophy. The expertise is of how to make a city resilient against internal and external conflict in light of the imperfect sociality of human (...) beings and the poverty of their reason. This expertise, however, cannot be produced on demand: one cannot train statesmen like one might train carpenters. Worse, it cannot be made acceptable to the citizens, or operate in ways that are not deeply destructive to the city's stability. Even as the political community requires his knowledge for its preservation, the genuine statesman must remain a stranger to the city. Marquez shows how this impasse is the key to understanding the ambiguous reevaluation of the rule of law that is the most striking feature of the political philosophy of the Statesman. The law appears here as a mere approximation of the expertise of the inevitably absent statesman, dim images and static snapshots of the clear and dynamic expertise required to steer the ship of state across the storms of the political world. Yet such laws, even when they are not created by genuine statesmen, can often provide the city with a limited form of cognitive capital that enables it to preserve itself in the long run, so long as citizens, and especially leaders, retain a “philosophical” attitude towards them. It is only when rulers know that they do not know better than the laws what is just or good (and yet want to know what is just and good) that the city can be preserved. The dialogue is thus, in a sense, the vindication of the philosopher-king in the absence of genuine political knowledge. (shrink)
BackgroundViral pandemics present a range of ethical challenges for policy makers, not the least among which are difficult decisions about how to allocate scarce healthcare resources. One important question is whether healthcare workers should receive priority access to a vaccine in the event that an effective vaccine becomes available. This question is especially relevant in the coronavirus pandemic with governments and health authorities currently facing questions of distribution of COVID-19 vaccines.Main textIn this article, we critically evaluate the most common ethical (...) arguments for granting healthcare workers priority access to a vaccine. We review the existing literature on this topic, and analyse both deontological and utilitarian arguments in favour of HCW prioritisation. For illustrative purposes, we focus in particular on the distribution of a COVID-19 vaccine. We also explore some practical complexities attendant on arguments in favour of HCW prioritisation.ConclusionsWe argue that there are deontological and utilitarian cases for prioritising HCWs. Indeed, the widely held view that we should prioritise HCWs represents an example of ethical convergence. Complexities arise, however, when considering who should be included in the category of HCW, and who else should receive priority in addition to HCWs. (shrink)
In this article we defend the inferential view of scientific models and idealisation. Models are seen as "inferential prostheses" construed by means of an idealisation-concretisation process, which we essentially understand as a kind of counterfactual deformation procedure . The value of scientific representation is understood in terms not only of the success of the inferential outcomes arrived at with its help, but also of the heuristic power of representation and their capacity to correct and improve our models. This provides us (...) with an argument against Sugden's account of credible models: the likelihood or realisticness is not always a good measure of their acceptability. As opposed to "credibility" we propose the notion of "enlightening", which is the capacity of giving us understanding in the sense of an inferential ability. (shrink)
There has been significant debate about whether the moral norms of medical practice arise from some feature or set of features internal to the discipline of medicine. In this article, I analyze Edmund Pellegrino’s conception of the internal morality of medicine, and situate it in the context of Alasdair MacIntyre’s influential account of “practice.” Building upon MacIntyre, Pellegrino argued that medicine is a social practice with its own unique goals—namely, the medical, human, and spiritual good of the patient—and that the (...) moral norms that govern medical practice are derived from these goals. After providing an overview of Pellegrino’s work, I discuss some forceful objections to his theory—specifically, that it is too rigid and incapable of entering into dialogue with contemporary values systems; that it is dependent on an external conception of human flourishing; and that it is incompatible with the rapidly changing nature of modern medicine. In the final section of this article, I consider how theorists working in the Hippocratic tradition might respond to these objections against ethical essentialism by drawing upon MacIntyre’s historico-cultural method as well as what he calls Aristotle’s “metaphysical biology.”.

Thomas Riisfeldt’s essay1 is a valuable contribution to the literature on palliative sedation, appropriately titrated administration of opioids and euthanasia. In this response, I will not deal with the author’s empirical claim about the relationship between opioid use, palliative sedation and survival time. Rather, I will briefly critique the author’s discussion of doctrine of double effect and its application to palliative sedation and opioid use at the end of life. That is, I will focus on the ethical claims made by (...) the author. Riisfeldt argues that DDE is incompatible with both Kantian deontology and Millian consequentialism. Yet, I will argue that the DDE is coherent and defensible when interpreted from the perspective of the philosophy of Thomas Aquinas, the theorist who first proposed the doctrine. I will also argue that Riisfeldt mischaracterises ATAOs and palliative sedation as procedures that hasten death as a means to relieve pain. While death may indeed be hastened by ATAOs and palliative sedation, it is not at all clear that clinicians intend to hasten death as a means to relieve pain. Indeed, clinical guidelines explicitly prohibit the intentional hastening of death. Riisfeldt provides a brief summary of the DDE. He describes DDE as a ‘strange hybrid of four principles’. He lists the four criteria that must be met for an act with a good and a bad effect to be permissible. These criteria are the ‘intention and means criteria’ and the ‘intrinsic and proportionality criteria’. The author uses Kant and Mill as lens through which to highlight a tension between the intrinsic and proportionality criteria of DDE. The author claims that ‘the intrinsic criterion is derived from deontology, the predominant form of which is championed by Kant’, and that ‘the proportionality criterion is derived from consequentialism, the predominant form of ….

We prove strong completeness of the □-version and the ◊-version of a Gödel modal logic based on Kripke models where propositions at each world and the accessibility relation are both infinitely valued in the standard Gödel algebra [0,1]. Some asymmetries are revealed: validity in the first logic is reducible to the class of frames having two-valued accessibility relation and this logic does not enjoy the finite model property, while validity in the second logic requires truly fuzzy accessibility relations and this (...) logic has the finite model property. Analogues of the classical modal systems D, T, S4 and S5 are considered also, and the completeness results are extended to languages enriched with a discrete well ordered set of truth constants.

Xavier Landes | : Happiness has become a central theme in public debates. Happiness indicators illustrate this importance. This article offers a typology of the main challenges conveyed by the elaboration of happiness indicators, where happiness can be understood as hedonia, subjective well-being, or eudaimonia. The typology is structured around four questions: what to measure?—i.e., the difficulties linked to the choice of a particular understanding of happiness for building an indicator; whom to include?—i.e., the limits of the community monitored (...) by such an indicator; how to collect the data?—i.e., the difficulties stemming from objective and subjective reporting; what to do?—i.e., the concerns about the use of happiness indicators in public policy. The major points of normative contention are discussed for each of these dimensions. The purpose of this article is to contribute in a constructive manner to happiness research by offering an overview of some major philosophical and political challenges of building happiness indicators. The conclusion underlines the importance of the strategy of diversification- hybridization, which consists in setting a variety of indicators or composite indicators that articulate different understandings of happiness. It is stressed that happiness indicators raise democratic and institutional issues with which normative thinkers should deal. | : Le bonheur est devenu un thème central dans les débats publics. Les indicateurs de bonheur illustrent cette importance. Cet article offre une typologie des principaux enjeux contenus dans le travail d’élaboration d’indicateurs de bonheur quand ce dernier est compris comme hedonia, bien-être subjectif ou eudaimonia. La typologie est structurée autour de quatre questions : 1) que mesurer?, où sont en jeu les difficultés liées au choix d’une compréhension particulière du bonheur pour construire un indicateur; 2) qui inclure?, c’est-à-dire comment tracer les limites de la communauté morale qui est l’objet d’un tel indicateur; 3) comment collecter les données?, où on interroge les difficultés propres aux techniques subjectives et objectives de collecte de données; 4) que faire?, où on soulève l’enjeu des craintes quant à l’usage d’indicateurs de bonheur dans les politiques publiques. Les points majeurs de dispute normative sont discutés pour chaque dimension. Nous espérons ainsi contribuer de manière constructive à la recherche sur le bonheur en offrant un aperçu de quelques défis philosophiques et politiques majeurs relatifs à la construction d’indicateurs de bonheur. Nous concluons en soulignant l’importance de la stratégie de diversification-hybridation qui consiste à mettre en place des indicateurs variés ou composites articulant différentes compréhensions du bonheur. Ces indicateurs soulèvent des enjeux démocratiques et institutionnels que les penseurs normatifs doivent considérer. (shrink)
Insurance is pervasive in many social settings. As a cooperative device based on risk pooling, it serves to attenuate the adverse consequences of various risks by offering policyholders coverage against the losses implied by adverse events in exchange for the payment of premiums. In the insurance industry, the concept of actuarial fairness serves to establish what could be adequate, fair premiums. Accordingly, premiums paid by policyholders should match as closely as possible their risk exposure. Such premiums are the product of (...) the probabilities of losses and the expected losses. This article presents a discussion of the fairness of actuarial fairness through three steps: defining the concept based on its formulation within the insurance industry; determining in which sense it may be about fairness; and raising some objections to the actual fairness of actuarial fairness. The necessity of a normative evaluation of actuarial fairness is justified by the influence of the concept on the current reforms of public insurance systems and the fact that it highlights the question of the repartition of the gains and burdens of social cooperation.

In this paper, we present a prenex form theorem for a version of Independence Friendly logic, a logic with imperfect information. Lifting classical results to such logics turns out not to be straightforward, because independence conditions make the formulas sensitive to signalling phenomena. In particular, nested quantification over the same variable is shown to cause problems. For instance, renaming of bound variables may change the interpretations of a formula, there are only restricted quantifier extraction theorems, and slashed connectives cannot be (...) so easily removed. Thus we correct some claims from Hintikka [8], Caicedo & Krynicki [3] and Hodges [11]. We refine definitions, in particular the notion of equivalence, and sharpen preconditions, allowing us to restore those claims, including the prenex form theorem of Caicedo & Krynicki [3], and, as a side result, we obtain an application to Skolem forms of classical formulas. It is a known fact that a complete calculus for IF-logic is impossible, but with our results we establish several quantifier rules that form a partial calculus of equivalence for a general version of IF-logic reflecting general properties of information flow in games.

Quines són les causes del dèficit filosòfic que arrossega la cultura catalana contemporània? Aquest llibre ofereix un panorama bastant complet —i amarg— de les condicions acadèmiques i extraacadèmiques en què s’ha hagut de conrear als Països Catalans la filosofia, tota la filosofia, centrant-se, això sí, en les aventures personals i col·lectives dels qui han tingut la vel·leïtat de dedicar-se a la lògica. Hi són narrades amb amenitat i lucidesa l’estada de Bertrand Russell a Barcelona, la defenestració d’Eugeni d’Ors, les aberracions (...) docents de Josep Daurella i Rull, la breu i fulgurant trajectòria intel·lectual de Joan Crexells, les peripècies eclesiàstiques de David Garcia Bacca i Miquel Soy, l’exili de Josep Ferrater Mora i la gestació del seu voluminós Diccionario de filosofía, la marginació de Manuel Sacristan, els conflictes de la Facultat de Filosofia de València en els anys 70... El resultat és una història de la filosofia apartada en molts aspectes de la imatge «abstracta» i «idealitzada» que sol oferir la historiografia filosòfica a l’ús. (shrink)
‘Epistemic’ arguments for conservatism typically claim that given the limits of human reason, we are better off accepting some particular social practice or institution rather than trying to consciously improve it. I critically examine and defend here one such argument, claiming that there are some domains of social life in which, given the limits of our knowledge and the complexity of the social world, we ought to defer to those institutions that have robustly endured in a wide variety of circumstances (...) in the past while not being correlated with intolerable outcomes. These are domains of social life in which our ignorance of optimal institutions is radical, and there is uncertainty about the costs of error. This is an argument for the preservation of particular institutions, not particular policies or outcomes, and it specifically identifies these with the institutions that John Rawls called ‘the basic structure of society.’ The argument further implies that to the extent that there is any reason to change these institutions, changes should be calculated as far as possible to increase their ‘epistemic power.’.

En enero de 1974 Zubiri dio un breve curso en la Sociedad de Estudios y Publicaciones de Madrid sobre el tema Tres dimensiones del ser humano: individual, social e histórica. Meses después publicó la última de esas lecciones bajo el título de La dimensión histórica del ser humano. El presente volumen recoge el texto de las tres conferencias, más la versión escrita de la última de ellas. La tesis que Zubiri desarrolla en estas lecciones es que el ser humano es (...) a la vez y necesariamente individual, social e histórico, y que estas dimensiones vienen exigidas por su propia realidad específica, que es pluralizante, continuante y prospectiva.

The aim of this paper is to strengthen the point made by Horty about the relationship between reason holism and moral particularism. In the literature prima facie obligations have been considered as the only source of reason holism. I strengthen Horty’s point in two ways. First, I show that contrary-to-duties provide another independent support for reason holism. Next I outline a formal theory that is able to capture these two sources of holism. While in simple settings the proposed account coincides (...) with Horty’s one, this is not true in more complicated or “realistic” settings in which more than two norms collide. My chosen formalism is so-called input/output logic. A bottom-line example is introduced. It raises the issue of whether the conventional wisdom is right in assuming that normative reasons run parallel to epistemic ones. (shrink)
Several bioethicists have recently discussed the complexity of defining human death, and considered in particular how our definition of death affects our understanding of the ethics of vital organ procurement. In this brief paper, we challenge the mainstream medical definition of human death—namely, that death is equivalent to total brain failure—and argue with Nair-Collins and Miller that integrated biological functions can continue even after total brain failure has occurred. We discuss the implications of Nair-Collins and Miller’s argument and suggest that (...) it may be necessary to look for alternative biological markers that reliably indicate the death of a human being. We reject the suggestion that we should abandon the dead-donor criteria for organ donation. Rather than weaken the ethical standards for vital organ procurement, it may be necessary to make them more demanding. The aim of this paper is not to justify the dead donor rule. Rather, we aim to explore the perspective of those who agree with critiques of the whole brain and cardiopulmonary definitions of death but yet disagree with the proposal that we should abandon the dead-donor rule. We will consider what those who want to retain the dead-donor rule must argue in light of Nair-Collins and Miller’s critique. (shrink)
Before his death in 1989, Gilbert Simondon wrote two major books consisting of his principal and complementary theses, both defended in 1958. The complementary thesis on the mode of existence of technical objects was published in 1958, while it was only in 1964 that sections of his principal thesis on individuation were made available to the public (and even then only the chapters dedicated to the regimes of physical and vital individuation, excluding those dealing with psychic and collective individuation.) Over (...) the course of his career, Simondon produced other major texts, but only in the form of unpublished courses or conference presentations published in poorly distributed journals. Some of these texts have .. (shrink)
This paper reports completeness results for dyadic deontic logics in the tradition of Hansson’s systems. There are two ways to understand the core notion of best antecedent-worlds, which underpins such systems. One is in terms of maximality, and the other in terms of optimality. Depending on the choice being made, one gets different evaluation rules for the deontic modalities, but also different versions of the so-called limit assumption. Four of them are disentangled, and compared. The main observation of this paper (...) is that, even in the partial order case, the contrast between maximality and optimality is not as significant as one could expect, because the logic remains the same whatever notion of best is used. This is established by showing that, given analogous properties for the betterness relation, the same system is sound and complete with respect to its intended modelling. The chief result of this paper concerns Åqvist’s system F supplemented with the principle of cautious monotony. It is established that, under the maximality rule, F + is sound and complete with respect to the class of models in which the betterness relation is required be reflexive and smooth . From this, a number of spin-off results are obtained. First and foremost, it is shown that a similar determination result holds for optimality; that is, under the optimality rule, F + is also sound and complete with respect to the class of models in which the betterness relation is reflexive and smooth . Other spin-off results concern classes of models in which further constraints are placed on the betterness relation, like totalness and transitivity. (shrink)
It is shown that axiomatic extensions of intuitionistic propositional calculus defining univocally new connectives, including those proposed by Gabbay, are strongly complete with respect to valuations in Heyting algebras with additional operations. In all cases, the double negation of such a connective is equivalent to a formula of intuitionistic calculus. Thus, under the excluded third law it collapses to a classical formula, showing that this condition in Gabbay's definition is redundant. Moreover, such connectives can not be interpreted in all Heyting (...) algebras, unless they are already equivalent to a formula of intuitionistic calculus. These facts relativize to connectives over intermediate logics. In particular, the intermediate logic with values in the chain of length n may be "completed" conservatively by adding a single unary connective, so that the expanded system does not allow further axiomatic extensions by new connectives.

We study a class of [0,1][0,1]-valued logics. The main result of the paper is a maximality theorem that characterizes these logics in terms of a model-theoretic property, namely, an extension of the omitting types theorem to uncountable languages.
In this study, in the light of Xavier Zubiri’s Metaphysics, we want to pay attention to the nuances of the term “transcendental”, trying to grasp shades and developments of its use in Zubiri’s thought to understand its originality and to be able to offer some clarifications on essential aspects of his philosophical system, in order to redefine his philosophy of reality as trans-physics.
This article examines the British colonial theft of Indigenous sovereignty and the particular obstacles that it presents to establishing just social relations between the colonizer and the colonized in settler states. In the first half, I argue that the particular nature of the crime of sovereign theft makes apologies and reparations unsuitable policy tools for reconciliation because Settler societies owe their very existence to the abrogation of Indigenous sovereignties. Instead, Settler states ought to return sovereignty to the land’s Indigenous peoples. (...) In the second half of this paper, I take up some of the practical questions of how this might be done and anticipate a number of objections. Giving up sovereignty would not mean dispossessing the millions of colonists who currently reside in these countries of their homes and property – but it does mean rethinking the constitutional makeup of a country and how that serves to benefit the different peoples who make their homes there.

An extensions by new axioms and rules of an algebraizable logic in the sense of Blok and Pigozzi is not necessarily algebraizable if it involves new connective symbols, or it may be algebraizable in an essentially different way than the original logic. However, extension whose axioms and rules define implicitly the new connectives are algebraizable, via the same equivalence formulas and defining equations of the original logic, by enriched algebras of its equivalente quasivariety semantics. For certain strongly algebraizable logics, all (...) connectives defined implicitly by axiomatic extensions of the logic are explicitly definable. (shrink)

Cuerpo físico y cuerpo vivido no deben interpretarse como dos realidades separadas, sino que representan dos aspectos distintos de la misma experiencia corporal descrita en términos fenomenológicos. La experiencia de la corporalidad puede seguir dos direcciones: a) la primera es una dirección ascendente, que implica el desarrollo de las posibilidades de movimiento, acción y expresión del cuerpo en toda su plenitud; b) el otro camino o dirección, en contraste con el anterior, toma una senda descendente, y se halla estrechamente relacionado (...) con la experiencia del dolor, de la limitación, de la resistencia corporal que es experimentada como oposición a la propia voluntad: es el cuerpo vulnerable. Aquí reaparece un nuevo dualismo: el cuerpo poético de la expresión frente al cuerpo vulnerable de la enfermedad y el dolor. Mi contribución trata de cuestionar la idea de que el cuerpo poético de la expresión artística y el cuerpo vulnerable de la vejez, de la discapacidad o de la enfermedad, pertenezcan a esferas completamente separadas. Con este propósito, se intenta poner de relieve los múltiples puntos de intersección entre ambas perspectivas, al tiempo que se sostiene que tales intersecciones pueden llegar a ser interesantes puntos de partida de la investigación interdisciplinar.

Even if the literature on the effects of pupil composition has been extensive, no clear consensus has been reached concerning the significance and magnitude of this effect. The first objective of this article is to estimate the magnitude of the school composition effect in primary schools (6th grade) in French-speaking Belgium. Different indicators of school composition are used: academic, socio-cultural, 'language' and sex composition. Except for sex composition, the results show that the school composition effect explains significant amount of between (...) schools variance even after controlling for pupils' initial performance, socio-cultural background, and non-cognitive dispositions. The second objective is to examine covariance between school composition and several organisational variables and their joint effect on school performance. The second set of analyses is intended to question the conceptual nature of the school composition effect, establishing whether it is direct or indirect. (shrink)
