Perception of time is susceptible to distortions; among other factors, it has been suggested that the perceived duration of a stimulus is affected by the observer’s expectations. It has been hypothesized that the duration of an oddball stimulus is overestimated because it is unexpected, whereas repeated stimuli have a shorter perceived duration because they are expected. However, recent findings suggest instead that fulfilled expectations about a stimulus elicit an increase in perceived duration, and that the oddball effect occurs because the (...) oddball is a target stimulus, not because it is unexpected. Therefore, it has been suggested that top-down attention is sometimes sufficient to explain this effect, and sometimes only necessary, with an additional contribution from saliency. However, how the expectedness of a target stimulus and its salient features affect its perceived duration is still an open question. In the present study, participants’ expectations about and the saliency of target stimuli were orthogonally manipulated with stimuli presented on a short (Experiment 1) or long (Experiment 2) temporal scale. Four repetitive standard stimuli preceded each target stimulus in a task in which participants judged whether the target was longer or shorter in duration than the standards. Engagement of top-down attention to target stimuli increased their perceived duration to the same extent irrespective of their expectedness. A small but significant additional contribution to this effect from the saliency of target stimuli was dependent on the temporal scale of stimulus presentation. In Experiment 1, saliency only significantly increased perceived duration in the case of expected target stimuli. In contrast, in Experiment 2, saliency exerted a significant effect on the overestimation elicited by unexpected target stimuli, but the contribution of this variable was eliminated in the case of expected target stimuli. These findings point to top-down attention as the primary cognitive mechanism underlying the perceptual extraction and processing of task-relevant information, which may be strongly correlated with perceived duration. Furthermore, the scalar properties of timing were observed, favoring the pacemaker-accumulator model of timing as the underlying timing mechanism. (shrink)

By giving sympathy a central role, Adam Smith’s Theory of Moral Sentiments (1759) can be regarded as one of the ‘enlightened’ moral theories of the Enlightenment, insofar as it widened the scope of moral consideration beyond the traditionally restricted boundary of human beings. This, although the author himself does not seem to have been aware of this fact. In this paper, I want to focus on two aspects which I think lead to this conclusion. First, by making sentience the requisite (...) to be taken into moral consideration, nonhuman animals in Smith’s moral theory can count as moral patients towards whom we should exercise the virtue of beneficence (if not justice). Secondly, Smith’s idea of morality as working in concentric circles –generating more stringent duties towards those closer to us– could explain and perhaps also justify our caring for some nonhuman animals, especially pets.

Narrowly understood, veganism is the practice of excluding all animal products from one’s diet, with the exception of human milk. More broadly, veganism is not only a food ethics, but it encompasses all other areas of life. As defined by the Vegan Society when it became an established charity in the UK in 1979, veganism is best understood as “a philosophy and way of living which seeks to exclude – as far as is possible and practicable – all forms of (...) exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of humans, animals and the environment”. There are two main moral justifications for veganism, both of which rely on a common assumption: that sentience, i.e., the capacity to feel pleasure and pain, is the necessary and sufficient trait to be morally considerable. In what follows, I present these two justifications and a third one which, although less popular, captures some core intuitions among vegans. I then present a challenge faced by veganism and two arguments that reject it as discriminatory, and briefly conclude. (shrink)

Given the conceptual gap in the global justice debate today (where most of the talk is about the duties of the rich, but little is said about what the poor may do for themselves), in this article I reintroduce the idea of a right of necessity. I first delineate a normative framework for such a right, inspired by these historical accounts. I then offer a contemporary case where the exercise of the right of necessity would be morally legitimate according to (...) that framework – even though illegal and probably condemned by the standard moral norms. The case is that of a small group of Paraguayan campesinos (small farmers) suffering from the effects of a severe drought. In the third part, I introduce the concept of noncivil disobedience: I call an act of noncivil disobedience a conscientious, public, illegal and forcible act whose performance, while not necessarily intended directly as a means to bring about social and/or political change, may help to trigger these changes indirectly. In the fourth part, I suggest that certain instances where the right of necessity is overtly exercised – as in the case of the famine-struck Paraguayan campesinos – may also be interpreted in terms of noncivil disobedience, insofar as they serve a double function: as a means of satisfying immediate need, and as a marker of discontent in a society where the equal rights of individuals are a nominal ideal which remains unfulfilled in practice. I then address two objections that may be raised against resurrecting the idea of a right of necessity and identifying it in certain instances with noncivil disobedience. I conclude by suggesting that, at the point of convergence between the two, a basic right like the right of necessity recovers its value as an active, (rather than passive) entitlement of its holders, while the use of force enters the picture as a legitimate means that – at least under certain circumstances – may be resorted to within the limits of civil society.

From the end of the twelfth century until the middle of the eighteenth century, the concept of a right of necessity –i.e. the moral prerogative of an agent, given certain conditions, to use or take someone else’s property in order to get out of his plight– was common among moral and political philosophers, who took it to be a valid exception to the standard moral and legal rules. In this essay, I analyze Samuel Pufendorf’s account of such a right, founded (...) on the basic instinct of self-preservation and on the notion that, in civil society, we have certain minimal duties of humanity towards each other. I review Pufendorf’s secularized account of natural law, his conception of the civil state, and the function of private property. I then turn to his criticism of Grotius’s understanding of the right of necessity as a retreat to the pre-civil right of common use, and defend his account against some recent criticisms. Finally, I examine the conditions deemed necessary and jointly sufficient for this right to be claimable, and conclude by pointing to the main strengths of this account. Keywords: Samuel Pufendorf, Hugo Grotius, right of necessity, duty of humanity, private property. (shrink)

he territorial impacts of climate change will affect millions. This will happen not only as a direct consequence of climate change, but also because of policies for mitigating it—for example, through the installation of large wind and solar farms, the conservation of land in its role as carbon sink, and the extraction of materials needed for renewable energy technologies. In this article, we offer an overview of the justice-related issues that these impacts create. The literature on climate justice and territory (...) is vast and spans a range of disciplines, so we limit our discussion to a specific understanding of territory and a specific understanding of injustice that arises from its loss. We understand territory as a normative concept that describes a place under some agent's jurisdiction, where the agent is a politically organized collective and where the jurisdictional rights over that place secure a relevant degree of self-determination for that collective. Accordingly, we consider that the main injustice connected to the loss of territory due to climate change is the loss or undermining of the ability to exercise the collective right to self-determination, which requires some control over the place. This can happen if a territorial agent literally loses the ground where to stand as a direct effect of climate change, raising issues of justice in relocation; or if their place changes due to mitigation policies, affecting their use and understanding of territory, raising issues of justice in energy transition. In concluding, we point to topics for future research. (shrink)

At the basis of modern natural law theories, the concept of the suum, or what belongs to the person (in Latin, his, her, its, their own), has received little scholarly attention despite its importance both in explaining and justifying not only the genealogy of property, but also that of morality and war.1 In this paper I examine Hugo Grotius's what it is, what things it includes, what rights it gives rise to and how it is extended in the transition from (...) the state of nature to civil society. I then briefly point out how bringing this concept back to the fore could help to illuminate the current discussion on the foundations of basic human rights, and to evaluate cases where these seem to clash with property rights.

According to the brain drain argument, there are good reasons for states to limit the exit of their skilled workers (more specifically, healthcare workers), because of the negative impacts this type of migration has for other members of the community from which they migrate. Some theorists criticise this argument as illiberal, while others support it and ground a duty to stay of the skilled workers on rather vague concepts like patriotic virtue, or the legitimate expectations of their state and co-citizens. (...) In this article, on the contrary, we suggest that the liberal conception of states’ legitimate political authority demands, and not just permits, that developing states from which migration of skilled workers occurs set up contractual mechanisms. These mechanisms will ensure that state-funded training in the health sector is provided against a commitment on the part of future professionals to reciprocate with their services for the benefits obtained. If one of the conditions for the state to maintain legitimate political authority is to provide basic services such as healthcare to its subjects (while respecting at the same time their autonomy and freedom), then this is what developing states affected by the brain drain ought to do. What we call the authority-based approach to the brain drain also helps to clarify the obligations that other states have not to interfere with these contractual mechanisms when they exist, and not to profit from their absence. Inspired by FIFA’s legal instruments of training compensation and solidarity mechanism for the transfer of players, we conclude by suggesting a plausible global policy to complement this authority-based approach.

The aim of this paper lies in characterizing the explanations and models used in the field of evolutionary developmental biology throughout its history. While manipulative experiments in controlled conditions have been useful to set the bases of the discipline and are still routinely performed, this approach supposes a tension between the reliability and the representativity of the conclusions. Given the recent changes in the understanding of evolutionary phenomena, different authors currently emphasize the need of avoiding excessive simplifications in experimental approaches, (...) incorporating the complexity of the analyzed systems as a relevant trait in the study of biological diversity. On the other hand, the fragile and contingent nature of evolutionary processes and the impossibility of intervening some of these phenomena underscore the importance of non-manipulative models that allow the elucidation of how-possibly mechanisms. We argue that a pluralism characterized by the integration of different kinds of explanations, models and metaphors used in evo-devo allows to exploit their respective advantages, favours interdisciplinarity and can contribute to form a representative description of evolutionary processes without relinquishing the local and detailed study of actual mechanisms.

The phrase ‘person‐centred care’ (PCC) reminds us that the fundamental philosophical goal of caring for people is to uphold or promote their personhood. However, such an idea has translated into promoting individualist notions of autonomy, empowerment and personal responsibility in the context of consumerism and neoliberalism, which is problematic both conceptually and practically. From a conceptual standpoint, it ignores the fact that humans are social, historical and biographical beings, and instead assumes an essentialist or idealized concept of personhood in which (...) a person is viewed as an individual static object. From a practical standpoint, the application of such a concept of personhood can lead to neglect of a person's fundamental care needs and exacerbate the problems of social inequity, in particular for older people and people with dementia. Therefore, we argue that our understanding of PCC must instead be based on a dynamic concept of personhood that integrates the relevant social, relational, temporal and biographical dimensions. We propose that the correct concept of personhood in PCC is one in which persons are understood as socially embedded, relational and temporally extended subjects rather than merely individual, autonomous, asocial and atemporal objects. We then present a reconceptualization of the fundamental philosophical goal of PCC as promoting selfhood rather than personhood. Such a reconceptualization avoids the problems that beset the concept of personhood and its application in PCC, while also providing a philosophical foundation for the growing body of empirical literature that emphasizes the psychosocial, relational, subjective and biographical dimensions of PCC.

The Ontology for Biomedical Investigations (OBI) is an ontology that provides terms with precisely defined meanings to describe all aspects of how investigations in the biological and medical domains are conducted. OBI re-uses ontologies that provide a representation of biomedical knowledge from the Open Biological and Biomedical Ontologies (OBO) project and adds the ability to describe how this knowledge was derived. We here describe the state of OBI and several applications that are using it, such as adding semantic expressivity to (...) existing databases, building data entry forms, and enabling interoperability between knowledge resources. OBI covers all phases of the investigation process, such as planning, execution and reporting. It represents information and material entities that participate in these processes, as well as roles and functions. Prior to OBI, it was not possible to use a single internally consistent resource that could be applied to multiple types of experiments for these applications. OBI has made this possible by creating terms for entities involved in biological and medical investigations and by importing parts of other biomedical ontologies such as GO, Chemical Entities of Biological Interest (ChEBI) and Phenotype Attribute and Trait Ontology (PATO) without altering their meaning. OBI is being used in a wide range of projects covering genomics, multi-omics, immunology, and catalogs of services. OBI has also spawned other ontologies (Information Artifact Ontology) and methods for importing parts of ontologies (Minimum information to reference an external ontology term (MIREOT)). The OBI project is an open cross-disciplinary collaborative effort, encompassing multiple research communities from around the globe. To date, OBI has created 2366 classes and 40 relations along with textual and formal definitions. The OBI Consortium maintains a web resource providing details on the people, policies, and issues being addressed in association with OBI. (shrink)

El acceso a la justicia como derecho, y el diseño e implementación de políticas públicas que lo tornen operante, exige un abordaje formativo crítico que se inscriba en la línea de una triple articulación: filosófica, jurídica y política. Enmarcada en dicha pretensión, la propuesta del curso “Agencias judiciales, políticas públicas y acceso a la justicia” tiene por objeto: a)Promover la reflexión sobre el acceso a la justicia como núcleo problemático de nuestra contemporaneidad social y jurídica. b)Reinscribir dicha reflexión crítica en (...) las filiaciones iusfilosóficas que la posibilitan e impulsan. c)Conceptualizar el acceso a la justicia como desafío medular de políticas de inclusión social.d)Identificar las complejidades que se derivan del carácter críptico y técnico que reviste el derecho moderno y el lenguaje jurídico que lo constituye, circunstancia que dificulta su accesibilidad y difusión. e)Efectuar aportes formativos que sirvan de base para la elaboración de políticas de acceso a la justicia que posibiliten la desarticulación de esta opacidad y formalización del lenguaje jurídico. f)Advertir el carácter performativo que porta el derecho como práctica social discursiva no solo como esfera de producción normativa sino también de construcción de las representaciones sociales que se disputan en la escena pública. g)Comprender el rol fundamental que poseen las agencias judiciales como instancias de promoción y desarrollo de políticas públicas en materia de acceso a la justicia. h)Esbozar los desafíos de dichas agencias judiciales para la profundización del acceso a la justicia como derecho vinculado a problemáticas específicas tales como la vulnerabilidad social y la diversidad cultural y lingüística.

The study of biodiversity spans many disciplines and includes data pertaining to species distributions and abundances, genetic sequences, trait measurements, and ecological niches, complemented by information on collection and measurement protocols. A review of the current landscape of metadata standards and ontologies in biodiversity science suggests that existing standards such as the Darwin Core terminology are inadequate for describing biodiversity data in a semantically meaningful and computationally useful way. Existing ontologies, such as the Gene Ontology and others in the Open (...) Biological and Biomedical Ontologies (OBO) Foundry library, provide a semantic structure but lack many of the necessary terms to describe biodiversity data in all its dimensions. In this paper, we describe the motivation for and ongoing development of a new Biological Collections Ontology, the Environment Ontology, and the Population and Community Ontology. These ontologies share the aim of improving data aggregation and integration across the biodiversity domain and can be used to describe physical samples and sampling processes (for example, collection, extraction, and preservation techniques), as well as biodiversity observations that involve no physical sampling. Together they encompass studies of: 1) individual organisms, including voucher specimens from ecological studies and museum specimens, 2) bulk or environmental samples (e.g., gut contents, soil, water) that include DNA, other molecules, and potentially many organisms, especially microbes, and 3) survey-based ecological observations. We discuss how these ontologies can be applied to biodiversity use cases that span genetic, organismal, and ecosystem levels of organization. We argue that if adopted as a standard and rigorously applied and enriched by the biodiversity community, these ontologies would significantly reduce barriers to data discovery, integration, and exchange among biodiversity resources and researchers.

The Plant Ontology (PO) is a community resource consisting of standardized terms, definitions, and logical relations describing plant structures and development stages, augmented by a large database of annotations from genomic and phenomic studies. This paper describes the structure of the ontology and the design principles we used in constructing PO terms for plant development stages. It also provides details of the methodology and rationale behind our revision and expansion of the PO to cover development stages for all plants, particularly (...) the land plants (bryophytes through angiosperms). As a case study to illustrate the general approach, we examine variation in gene expression across embryo development stages in Arabidopsis and maize, demonstrating how the PO can be used to compare patterns of expression across stages and in developmentally different species. Although many genes appear to be active throughout embryo development, we identified a small set of uniquely expressed genes for each stage of embryo development and also between the two species. Evaluating the different sets of genes expressed during embryo development in Arabidopsis or maize may inform future studies of the divergent developmental pathways observed in monocotyledonous versus dicotyledonous species. The PO and its annotation databasemake plant data for any species more discoverable and accessible through common formats, thus providing support for applications in plant pathology, image analysis, and comparative development and evolution.

I min artikel ”Att förstå – betraktelser utifrån en ny teori” (FT 31:4 Nov 2010) vill jag visa att det finns anledning att förtydliga förståelsebegreppet. Avsevärd möda har, historiskt sett, lagts ned på att definiera och bringa klarhet i begreppen kunskap och förklaring men förståelse, som når längre än vanlig kunskap, har förblivit ett otydligt begrepp. Teorin jag lägger fram i artikeln har som sin kärna en definition av förståelse. Denna utkristalliseras dels naturligt från vår vardagliga användning, dels från behovet (...) av att tydligt visa på vilket sätt förståelse är den djupaste formen av kunskap, av medveten insikt. Först när förståelsebegreppet utgör ett väl format verktyg kan kunskapsteorin nå sin fulla potential. Jag är tacksam gentemot Anders Tolland för att ha kritiskt granskat artikeln och för att han ger mig möjlighet att uttrycka teorin klarare. Tollands kritik berör främst oklarheter avseende innehållet i de abstraktioner som, tillsammans med jämförelser, är centrala element i teorin. Tolland bidrar också till förtydliganden, för vilka jag är mycket tacksam. Särskilt vill jag nämna påpekandena att förståelse dels kan relatera till vad något är, dels till varför det är på det sättet och att förståelse dels är en process, dels ett uppnått tillstånd. I det följande bemöter jag Tollands kritik och anser mig verkligen kunna visa att den framlagda teorin för förståelse är sammanhållen, tydlig och alls icke ”kontra-intuitiv” samt att den utgör ett viktigt, nytt kunskapsteoretiskt verktyg.

As touch remains commonly defined by the closeness it physically implies and it rhetorically evokes, the mere notion of distant touch and of distal haptic perception seems peculiar. But Aristotle’s perspective, which I wish to take as a point of departure, is firm: we perceive the objects of touch, the hot and the cold, the hard and the soft, the curved and the sharp, through other things: δι' ἑτέρων. In this article, I would like to explore this ἕτερος by showing (...) how the otherness of perception always implies an intermediary, a middle point (μέσος), i.e. an other not so other, an other that is able to translate the much more distant otherness of the perceived object. To explore these forgotten layers of alterity that fall into what we commonly conceive of as the impalpable emptiness of distance, I propose to study the idea of distant touch from the perspective of phenomenological aesthetics. In order to do so, I will first examine some aspects of the Husserlian account of perception and will then focus on the phenomenology of distant touch in Alejandra Costamagna’s novel El Sistema del Tacto [The System of Touch] (2018).

Interdisciplinary dialogue acts as a symbiosis for all the areas that participate and imply enormous projections for both art and science. This paper explores the potential of an interdisciplinary dialogue between Biology and Performance using as a case study the Performance Analfabeta created by the artist Paulina Bronfman. The work was shaped in the context of The Third Conference of the Nucleus of Artistic Research (NIA) of In/Inter/Disciplinary Laboratories hosted by the Faculty of Art of The Pontificia University of Chile (...) (LAB IID). The Lab was led by Chilean biologist Alejandra Zuñiga- Feest and the Brazilian artist Adriana Parente La Selva. This work aims to explore the questions: what does it mean, from the point of view of the arts and sciences, to develop an interdisciplinary laboratory? How is this done? This paper problematizes the creative process of collaboration between sciences and performance as well as the potential impact and link with society that this multidisciplinary dialogue can have.

Primero se analiza el concepto de imaginación en Descartes y se sostiene que el concepto es equívoco, ya que en un sentido carece de valor epistémico pero en otro sentido sí lo tiene. A continuación se explora el concepto de imaginación como una facultad subordinada al entendimiento y se observan sus repercusiones en Spinoza y Leibniz. Finalmente se exponen las críticas (...) de Kant y Hume con respecto a los límites del entendimiento y se ofrece una posible crítica de Hume a Descartes en torno a la imaginación y el entendimiento.
