On the ethics of extending human life: healthy people have a right to carry on livingHumanity has long demonstrated a paradoxical ambivalence concerning the extension of a healthy human lifespan. Modest health extension has been universally sought, whereas extreme health extension has been regarded as a snare and delusion—a dream beyond all others at first blush, but actually something we are better off without. The prevailing pace of biotechnological progress is bringing ever closer the day when humanity will be able (...) to act on the latter view by rejecting a clear and present opportunity for much longer healthy lives. Indeed, some biogerontologists contend that that day has already arrived, to the extent that our hesitation in embarking on a vigorous “war on ageing” is already delaying the point at which a cure for ageing will be developed. Here I consider whether our present caution concerning the wisdom of truly curing ageing is likely to survive the increased scrutiny that it will receive in coming years as a result of these technical advances. I conclude that it will not, because of its irreconcilability with values that are more deeply held by the large majority of humanity than any values that argue against the quest for a cure. I further conclude that all the major current reasons given for not curing ageing are mere crutches to help us cope with the immutability of ageing that we have been brought up to accept. Our failure to set aside such irrationality is already shortening potential longevity—quite probably of those already alive today—to a staggering degree. Once we realise this, our determination to consign human ageing to history will be second …. (shrink)

As a leader of the crusade to defeat aging, working to demonstrate both its feasibility and its desirability, I am often seen as an implacable opponent of all arguments that defend aging and criticize this crusade. This is an oversimplification.

The feasibility of reversing human aging within a matter of decades has traditionally been dismissed by all professional biogerontologists, on the grounds that not only is aging still poorly understood, but also many of those aspects that we do understand are not reversible by any current or foreseeable therapeutic regimen. This broad consensus has recently been challenged by the publication, by five respected experimentalists in diverse subfields of biogerontology together with three of the present authors, of an article (Ann NY (...) Acad Sci 959, 452–462) whose conclusion was that all the key components of mammalian aging are indeed amenable to substantial reversal (not merely retardation) in mice, with technology that has a reasonable prospect of being developed within about a decade. Translation of that panel of interventions to humans who are already alive, within a few decades thereafter, was deemed potentially feasible (though it was not claimed to be likely). If the prospect of controlling human aging within the foreseeable future cannot be categorically rejected, then it becomes a matter of personal significance to most people presently alive. Consequently, we suggest that serious public debate on this subject is now warranted, and we survey here several of the biological, social and political issues relating to it.

Over recent years, evidence has been accumulating in favour of the free radical theory of aging, first proposed by Harman. Despite this, an understanding of the mechanism by which cells might succumb to the effects of free radicals has proved elusive. This paper proposes such a mechanism, based on a previously unexplored hypothesis for the proliferation of mutant mitochondrial DNA: that mitochondria with reduced respiratory function, due to a mutation or deletion affecting the respiratory chain, suffer less frequent lysosomal degradation, (...) because they inflict free radical damage more slowly on their own membranes. Once such a mutation occurs in a mitochondrion of a non‐dividing cell, therefore, mitochondria carrying it will rapidly populate that cell, thereby destroying the cell's respiratory capability. The accumulation of cells that have undergone this transition results in aging at the organismal level. The consistency of the hypothesis with known facts is discussed, and technically feasible tests are suggested, of both the proposed mechanism and its overall contribution to mammalian aging.

The 2013 Rostock Symposium on Systems Biology and Bioinformatics in Aging Research was again dedicated to dissecting the aging process using in silico means. A particular focus was on ontologies, as these are a key technology to systematically integrate heterogeneous information about the aging process. Related topics were databases and data integration. Other talks tackled modeling issues and applications, the latter including talks focussed on marker development and cellular stress as well as on diseases, in particular on diseases of kidney (...) and skin.

El pasaje de la Elegía de Gray (PEG) en “On Denoting” es extremadamente obscuro y ha sido objeto de muy diversas interpretaciones. Aparentemente contiene una crítica devastadora contra la teoría de los conceptos denotativos que el propio Russell había postulado en The Principles of Mathematics (PM) (1903). En este artículo exponemos sucintamente dicha teoría semántica, examinamos detalladamente el pasaje en cuestión y exploramos algunas de las interpretaciones que pretenden desentrañar su sentido. Con ello mostramos, en primer lugar, que la crítica (...) se dirige directamente contra la teoría de PM; en segundo lugar, que no es posible hacer unos pocos cambios homogéneos para habilitar una lectura literal del pasaje; finalmente, que, si bien algunos de los argumentos que los intérpretes han aducido para abandonar la teoría de los conceptos denotativos son sólidos, no es obvio que todos ellos se encuentren en PEG.

This article proposes an original analysis of the international debate on climate change through the use of digital methods. Its originality is twofold. First, it examines a corpus of reports covering 18 years of international climate negotiations, a dataset never explored before through digital techniques. This corpus is particularly interesting because it provides the most consistent and detailed reporting of the negotiations of the United Nations Framework Convention on Climate Change. Second, in this paper we test an original approach to (...) text analysis that combines automatic extractions and manual selection of the key issue-terms. Through this mixed approach, we tried to obtain relevant findings without imposing them on our corpus. The originality of our corpus and of our approach encouraged us to question some of the habits of digital research and confront three common misunderstandings about digital methods that we discuss in the first part of the article. In addition to reflecting on methodology, however, we also wanted to offer some substantial contribution to the understanding of UN-framed climate diplomacy. In the second part of the article we will therefore introduce some of the preliminary results of our analysis. By discussing three visualizations, we will analyze the thematic articulation of the climatic negotiations, the rise and fall of these themes over time and the visibility of different countries in the debate.

BackgroundThe ARRIVE (Animal Research: Reporting of In Vivo Experiments) guidelines are widely endorsed but compliance is limited. We sought to determine whether journal-requested completion of an ARRIVE checklist improves full compliance with the guidelines.MethodsIn a randomised controlled trial, manuscripts reporting in vivo animal research submitted to PLOS ONE (March–June 2015) were randomly allocated to either requested completion of an ARRIVE checklist or current standard practice. Authors, academic editors, and peer reviewers were blinded to group allocation. Trained reviewers performed outcome adjudication (...) in duplicate by assessing manuscripts against an operationalised version of the ARRIVE guidelines that consists 108 items. Our primary outcome was the between-group differences in the proportion of manuscripts meeting all ARRIVE guideline checklist subitems.ResultsWe randomised 1689 manuscripts (control: n = 844, intervention: n = 845), of which 1269 were sent for peer review and 762 (control: n = 340; intervention: n = 332) accepted for publication. No manuscript in either group achieved full compliance with the ARRIVE checklist. Details of animal husbandry (ARRIVE subitem 9b) was the only subitem to show improvements in reporting, with the proportion of compliant manuscripts rising from 52.1 to 74.1% (X2 = 34.0, df = 1, p = 2.1 × 10−7) in the control and intervention groups, respectively.ConclusionsThese results suggest that altering the editorial process to include requests for a completed ARRIVE checklist is not enough to improve compliance with the ARRIVE guidelines. Other approaches, such as more stringent editorial policies or a targeted approach on key quality items, may promote improvements in reporting. (shrink)

Le Socrate de Xénophon et la démocratie présente une interprétation nuancée du témoignage de Xénophon sur l’attitude de Socrate à l’endroit de la démocratie athénienne. Cette étude conteste les interprétations qui ont été trop restrictives dans le choix des témoignages et trop négatives dans leurs conclusions. Elle tient compte, d’une part, des différents paramètres qui permettent de définir la démocratie ; d’autre part, des réalités de la démocratie athénienne. Les principaux textes pertinents proviennent des Mémorables. Nous traitons de la nature (...) de cet ouvrage et de la façon dont il expose l’attitude de Socrate à l’endroit des lois et des institutions du régime démocratique, notamment l’assemblée et le tirage au sort. Cette étude présente enfin une interprétation plus nuancée de la propre attitude de Xénophon à l’endroit de la démocratie, attitude qui a elle-même influé sur la façon dont on a, par le passé, évalué l’attitude de son Socrate.Xenophon’s Socrates and Democracy offers a balanced interpretation of Xenophon’s evidence for Socrates’ attitude to the Athenian democracy, arguing against interpretations that have been too selective in their evidence and too negative in their conclusions. It takes due account of the various parameters that define democracy and the realities of Athenian democracy. The main evidence is from Memorabilia. There is discussion of nature of this work, and then of how it expresses Socrates’ attitude to the laws of the democracy and other processes such as sortition and the assembly. The paper also offers a more balanced interpretation of Xenophon’s own attitude to democracy, which has influenced past assessments of the attitude of his Socrates. (shrink)

This is a section of Mr. Gray's recent paper read before The Philosophers' Academy covering "The Catholic Movement in France and the Philosophy of de Lamennais".Complete ignorance of the system of the Medieval Schoolmen seems responsible for the contempt in which he held Scholasticism, and indirectly for the vagaries of his own philosophy, and the ultimate shipwreck of his faith.

SAMANTHA GREY | : Prevailing connotations of reconciliation orbit concord or harmonious coexistence, meaning that concern for justice is necessarily subordinated to a more casually pragmatic peace.

Kevin Gray,Kafumu Kalyalya | : In this paper we challenge the role of consent in the global order by discussing current modes of international law making in the global order. We contend that the features of state consent in international law depart substantially from those assumed by theorists of the liberal order, who subscribe, in most cases, to the realist conception of state action. We argue, against those theorists, that state consents to coercive measures, and the state’s role in carrying (...) them out, has ceased to be central to an account of global law. We conclude that international law—often thought of as law beyond the state—now has expanded its scope to reach individuals and corporations, and that this change has important ramifications for theories of global justice. | : Dans cet article, nous interrogeons le rôle de l’accord dans l’ordre global en discutant les modes courants de constitution des lois internationales au sein de cet ordre. Nous prétendons que les fonctions de l’accord étatique en loi internationale s’écartent substantiellement de celles assumées par les théoriciens de l’ordre libéral, qui souscrivent, dans la plupart des cas, à la conception réaliste de l’action étatique. Contre ces théoriciens, nos posons que l’État consent à des mesures coercitives, et que le rôle de l’État d’effectuer celles-ci a cessé d’être central dans l’explication de la loi globale. Nous concluons que la loi internationale – souvent pensée comme une loi hors de l’État – a maintenant étendu son spectre jusqu’aux individus et corporations, et que ce changement a d’importantes ramifications que les théories globales de la justice devraient considérer.

Forty-nine commentators have reviewed the theory that needs-based stresses and freedoms are shaped differently in threatening, comforting, and challenging climato-economic habitats. Their commentaries cover the white domain, where the theory does apply (e.g., happiness, collectivism, and democracy), the gray domain, where it may or may not apply (e.g., personality traits and creativity), and the black domain, where it does not apply (e.g., human intelligence and gendered culture). This response article provides clarifications, recommendations, and expectations.

RESUMEN Se realizó un estudio descriptivo transversal cuanti-cualitativo, en función de la caracterización sicológica de los adolescentes con ideación suicida, atendidos en la consulta de Sicología del Centro Comunitario de Salud Mental “Joaquín de Agüero” del área de salud Pirre, Finlay y Norte en la provincia de Camagüey, en el período comprendido desde enero hasta diciembre de 2016. Por ello el objetivo del presente trabajo está dirigido a exponer los principales resultados del proceso de investigación al que se alude. Se (...) operó con un universo de 16 adolescentes. Se utilizó un muestreo intencional puro con criterios de inclusión y exclusión, la muestra quedó conformada por 13. Se emplearon métodos de nivel teórico, empíricos:, Test funcionamiento familiar, Idaren, Ideren, Autoestima de Coopersmith) y métodos estadísticos. Predominó el grupo etario entre 13 a 15 años, sexo femenino, escolaridad secundaria y estado civil soltero. Prevalecieron las familias nucleares monoparentales y reensambladas. El poco tiempo a compartir con los hijos pobre comunicación y conflictos con los padres son factores de riesgo en el funcionamiento familiar. La autoestima se comportó a niveles bajo, con carencia afectiva, sentimientos de soledad, falta de apoyo y poca tolerancia a las frustraciones. Se constataron niveles altos de ansiedad como estado y rasgo, la depresión como estado alto y como rasgo bajo y se encontró dañada la tríada afectiva. ABSTRACT A descriptive transversal quantitative-qualitative study was carried out in order to do a psychological characterization of teenagers with suicidal ideation. They were treated in the psychology consultation of the Joaquin de Aguero Mental Health Community Center from the Pirre, Finlay and North policlinics health area in Camaguey province from January to December 2016. Therefore, this paper is aimed at showing the main results of the research process which is made reference to. Sixteen teenagers were selected as population. A pure intentional sampling with inclusion and exclusion criteria was used and the final sample was 13 teenagers. Different methods were used: theoretical, empirical ), Family functioning test, Idaren, Ideren, Coopersmith Self-esteem) and statistical methods. It prevailed an age bracket between 13 and 15-year-old high school single teens. It prevailed nuclear single-parent and rejoined families. The short time parents share with children as well as the poor communication and the conflicts between them are family functioning risk factors. Self-esteem levels were low, with affection deprivation, loneliness feelings, lack of support and little tolerance towards frustrations. High anxiety levels such as state and trait were confirmed, as well as high state and low trait. The affective triad was found to be damaged. (shrink)

Some maladaptive thought processes are characterized by reflexive and habitual patterns of cognitive and emotional reactivity. We review theoretical and empirical work suggesting that mindfulness—a state of nonjudgmental awareness of the present moment—can facilitate the discontinuation of such automatic mental operations. We propose a framework that suggests a series of more specific mechanisms supporting the de-automatizing function of mindfulness. Four related but distinct elements of mindfulness (awareness, attention, focus on the present, and acceptance) can each contribute to de-automatization through subsequent (...) processes, including discontinuing automatic inference, enhancing cognitive control capacity, facilitating metacognitive insight, and preventing suppression or thought distortion. De-automatizing can, in turn, allow enhancement of adaptive self-control ability and increased well-being. (shrink)

Nicholas Agar, Jeff McMahan and Allen Buchanan have all expressed concerns about enhancing humans far outside the species-typical range. They argue radically enhanced beings will be entitled to greater and more beneficial treatment through an enhanced moral status, or a stronger claim to basic rights. I challenge these claims by first arguing that emerging technologies will likely give the enhanced direct control over their mental states. The lack of control we currently exhibit over our mental lives greatly contributes to our (...) sense of vulnerability. I then argue moral status should be viewed in terms of vulnerability. The enhanced will slowly gain the ability to command their mental states, reducing their vulnerability. These radically enhanced beings will have greater capacities, and possibly an inner life more valuable than our own. They will also be less vulnerable, and as a result, their moral status will be subordinate to our own. (shrink)

A philosophical frame for violence against women and girls creates unique opportunities to deepen our understanding of the embodied consequences of men’s violence. Using the seemingly innocuous example of being told to “cheer up” or “smile”, we draw on Simone de Beauvoir and Franz Fanon’s work on recognition to suggest that a phenomenological approach to sexual violence may help to voice previously inarticulable harms. The dual frame of Beauvoir and Fanon also highlights the need for philosophical work on sexual violence (...) to take account of the insights of intersectionality. (shrink)
