During a cultural festival, artists and theaters act as a cartel by agreeing on pricing decisions that maximize the groups’ profit as a whole. We model the problem of sharing the profit created by a festival among organizing theaters as a cooperative game. In such a game, the worth of a coalition is defined as the theaters’ profit from the optimal fixation of prices. We show that this class of games is convex and we axiomatically characterize the Shapley value for (...) this class of games. We also provide an axiomatic basis for the downstream incremental solution. Finally, we apply this model to the NEXT festival, for which we have collected data. We propose an approach to derive the games’ vector from the data and we compute the different solutions. (shrink)

Celtic mythology, Arthurian romance and an intriguing interpretation of British history – these are just some of the themes embraced by the anonymous authors of the eleven tales that make up the Welsh medieval masterpiece known as.

The idea that deep brain stimulation (DBS) induces changes to personality, identity, agency, authenticity, autonomy and self (PIAAAS) is so deeply entrenched within neuroethics discourses that it has become an unchallenged narrative. In this article, we critically assess evidence about putative effects of DBS on PIAAAS. We conducted a literature review of more than 1535 articles to investigate the prevalence of scientific evidence regarding these potential DBS-induced changes. While we observed an increase in the number of publications in theoretical neuroethics (...) that mention putative DBS-induced changes to patients’ postoperative PIAAAS, we found a critical lack of primary empirical studies corroborating these claims. Our findings strongly suggest that the theoretical neuroethics debate on putative effects of DBS relies on very limited empirical evidence and is, instead, reliant on unsubstantiated speculative assumptions probablyin lieuof robust evidence. As such, this may reflect the likelihood of a speculative neuroethics bubble that may need to be deflated. Nevertheless, despite the low number of first-hand primary studies and large number of marginal and single case reports, potential postoperative DBS changes experienced by patients remain a critical ethical concern. We recommend further empirical research in order to enhance theoretical neuroethics work in the area. In particular, we call for the development of better instruments capable of capturing potential postoperative variations of PIAAAS. (shrink)

The phenomenological effects of deep brain stimulation (DBS) on the self of the patient remains poorly understood and under described in the literature, despite growing evidence that a significant number of patients experience postoperative neuropsychiatric changes. To address this lack of phenomenological evidence, we conducted in-depth, semistructured interviews with 17 patients with Parkinson's disease who had undergone DBS. Exploring the subjective character specific to patients' experience of being implanted gives empirical and conceptual understanding of the potential phenomenon of DBS-induced self-estrangement. (...) Our study concluded that (1) the more patients preoperatively felt alienated by their illness, the more they experienced postoperative self-estrangement, and (2) the notion of self-estrangement seems to exist in association with certain common qualitative characters, namely, loss of control, which reflects a deteriorative estrangement, and distorted perception of capacities, which reveals a restorative estrangement. These findings indicate that subjective self-reports help us to understand some aspects of the potential phenomenon of DBS-induced self-estrangement. (shrink)

Geron recently announced that it had begun enrolling patients in the world's first-in-human clinical trial involving cells derived from human embryonic stem cells (hESCs). This trial raises important questions regarding the future of hESC-based therapies, especially in spinal cord injury (SCI) patients. We address some safety and efficacy concerns with this research, as well as the ethics of fair subject selection. We consider other populations that might be better for this research: chronic complete SCI patients for a safety trial, subacute (...) incomplete SCI patients for an efficacy trial, and perhaps primary progressive multiple sclerosis (MS) patients for a combined safety and efficacy trial.

Why and how do norms emerge? Which norms emerge and why these ones in particular? Such questions belong to the ‘problem of the emergence of norms’, which consists of an inquiry into the production of norms in social collectives. I address this question through the ethnographic study of the emergence of ‘norms against violence’ in the political collective Occupy Geneva. I do this, first, empirically, with the analysis of my field observations; and, second, theoretically, by discussing my findings. In consequence (...) of two episodes categorized as sexual assaults that occurred in their camp, the members of Occupy Geneva decided to tackle those issues in a general assembly. Their goal was to amend their first charter of good conduct in order to reform its norms and complete it with norms aiming to regulate ‘facts’ of ‘unjustified violence’. During a collective deliberation, new norms were devised, debated and consensually adopted. The writing of the new charter took place in a second general assembly during which the wording of the written norms was collectively decided. I show that indignation over the sexual assaults was the main motive that led to the collective deliberation, and that the entire process of the making of these norms was characterized by different collective emotions. Indeed, indignation, contempt and fear played major roles in the emergence of norms prohibiting violence, allowing punishment and exclusion of wrongdoers, and prescribing collective intervention against an aggressor to neutralize the threat represented. These findings prompt me to hypothesize that social norms emerge from emotions thanks to the latters’ internal structure; and that emotions provide causal and grounding explanations for this emergence. Thus, emotions allow us to answer the questions: ‘Why do norms emerge?’ and ‘Why do they have their specific forms?’ In short, I argue that social norms have emotional foundations. (shrink)

Cet article s’intéresse au problème de la maintenance, c’est-à-dire au moment où les membres d’un collectif social tentent d’assurer dans le temps l’existence de leur collectif en instituant des règles pour réguler leurs comportements. Ce problème se pose avec acuité lorsque certains membres ne respectent pas ces règles communes. Pour maintenir la coopération sociale, les membres peuvent décider d’instituer des règles secondaires visant à sanctionner les transgressions des règles primaires déjà établies. La maintenance d’un collectif peut ainsi reposer sur l’émergence (...) de pouvoirs déontiques qui donnent aux membres l’autorité de légitimement punir et expulser les transgresseurs. Mais d’où viennent ces règles ? On peut penser qu’elles émergent des émotions éprouvées par les membres envers les transgresseurs. Je le démontre à l’aide d’une étude de cas qui établit que, dans le collectif Occupy Geneva, l’institutionnalisation de normes pour punir, exclure et réintégrer les déviants s’ancraient respectivement dans l’indignation, le mépris et le pardon. -/- This article focuses on the problem of maintenance; that is the moment when the members of a social collective attempt to ensure the existence of their collective over time by instituting rules to regulate their behavior. This problem becomes critical when certain members do not respect the common rules. To maintain social cooperation, members can decide to institute secondary rules aimed at sanctioning the transgressions of the already established primary rules. The maintenance of a collective can thus rely on the emergence of deontic powers that give members the authority to legitimately punish and expel transgressors. But where do these rules come from? The hypothesis is that they emerge from the emotions felt by the members towards the transgressors. I show this with the help of a case study, which establishes that the institutionalization of norms allowing the punishment, the exclusion, and the reintegration of deviants within the “Occupy Geneva” collective, was grounded in indignation, contempt, and forgiveness respectively.

At the phenomenal level, consciousness can be described as a singular, unified field of recursive self-awareness, consistently coherent in a particualr way; that of a subject located both spatially and temporally in an egocentrically-extended domain, such that conscious self-awareness is explicitly characterized by I-ness, now-ness and here-ness. The psychological mechanism underwriting this spatiotemporal self-locatedness and its recursive processing style involves an evolutionary elaboration of the basic orientative reference frame which consistently structures ongoing spatiotemporal self-location computations as i-here-now. Cognition computes action-output (...) in the midst of ongoing movement, and consequently requires a constant self-locating spatiotemporal reference frame as basis for these computations. Over time, constant evolutionary pressures for energy efficiency have encouraged both the proliferation of anticipative feedforward processing mechansims, and the elaboration, at the apex of the sensorimotor processing hierarchy, of self-activating, highly attenuated recursively-feedforward circuitry processing the basic orientational schema independent of external action output. As the primary reference frame of active waking cognition, this recursive i-here-now processing generates a zone of subjective self-awareness in terms of which it feels like something to be oneself here and now. This is consciousness. (shrink)

The traditional international law of self-defense provides little indication about how far states should be willing to defend. That choice is better understood as constrained, beyond the jus in bello and the jus ad bellum, by human rights norms that implicate responsibilities of the sovereign vis-à-vis its own population. Different conceptions of human rights, however, underscore different possible theories of the extent of self-defense. The main polarity is between a conception of self-defense as protecting bare life and a conception of (...) self-defense as protecting collective self-determination. In the practice of justifying particular uses of self-defense, these foundations are constantly and dynamically rearticulated to justify fighting on, surrendering, or negotiating. This raises questions about the impact of conditions of uncertainty, different conceptions of agency, and the role of the international community. Ultimately, the article suggests that self-defense radicalizes anxieties about the foundation and finality of rights. (shrink)

This is an important new book about human motivation, about the reasons people have for their actions. What is distinctively new about it is its focus on how people see or understand their situations, options, and prospects. By taking account of people's understandings, Professor Schick is able to expand the current theory of decision and action. The author provides a perspective on the topic by outlining its history. He defends his new theory against criticism, considers its formal structure, and shows (...) at length how it resolves many currently debated problems: the problems of conflict and weakness of will, Allais' problem, Kahneman and Tversky's problems, Newcomb's problem, and others. The book will be of special interest to philosophers, psychologists, and economists. (shrink)

In this article, we explore the implications of a Rawlsian theory for intergenerational issues. First, we confront Rawls's way of locating his `just savings' principle in his Theory of Justice with an alternative way of doing so. We argue that both sides of his intergenerational principle, as they apply to the accumulation phase and the steady-state stage, can be dealt with on the bases, respectively, of the principle of equal liberty and of the difference principle. We then proceed by focusing (...) on the implications of applying maximin to his steady-state stage. One central claim is that, in principle, Rawlsians should consider not only generational dissavings, but also generational savings, as unfair. This principle suffers a series of exceptions on which we focus in the fourth section of the article. In some cases, growth can be maximin compatible. (shrink)

Two different kinds of collections have been used to anticipate influenza pandemics: viral strains and bird specimens. These collections have been organized in museums and data banks to fill the gaps when specimens were decaying or when viral strains were missing. This article asks how collecting practices changed when such collections integrated specimens from China, considered a reservoir of influenza viruses and bird species, following a recurrent critical trope that Chinese specimens were missing. The article shows that techniques for hunting (...) viruses and birds were used to accumulate information so as to mitigate the global threat of species extinction. It suggests that in sentinel territories, museums transform samples and specimens into signs and images of future catastrophic events. (shrink)

Although an invasive medical intervention, Deep Brain Stimulation (DBS) has been regarded as an efficient and safe treatment of Parkinson’s disease for the last 20 years. In terms of clinical ethics, it is worth asking whether the use of DBS may have unanticipated negative effects similar to those associated with other types of psychosurgery. Clinical studies of epileptic patients who have undergone an anterior temporal lobectomy have identified a range of side effects and complications in a number of domains: psychological, (...) behavioural, affective and social. In many cases, patients express difficulty adjusting from being chronically ill to their new status as ‘treated’ or ‘seizure free’. This postoperative response adjustment has been described in the literature on epilepsy as the ‘Burden of Normality’ (BoN) syndrome. Most of the discussion about DBS postoperative changes to self is focused on abnormal side effects caused by the intervention (ie, hypersexuality, hypomania, etc). By contrast, relatively little attention is paid to the idea that successfully ‘treated’ individuals might experience difficulties in adjusting to becoming ‘normal’. The purpose of this paper is (1) to articulate the postoperative DBS psychosocial adjustment process in terms of the BoN syndrome, (2) to address whether the BoN syndrome illustrates that DBS treatment poses a threat to the patient’s identity, and (3) to examine whether the current framework for rehabilitation after DBS procedures should be updated and take into account the BoN syndrome as a postoperative self-change response.

We argue that a fashionable interpretation of the theory of natural selection as a claim exclusively about populations is mistaken. The interpretation rests on adopting an analysis of fitness as a probabilistic propensity which cannot be substantiated, draws parallels with thermodynamics which are without foundations, and fails to do justice to the fundamental distinction between drift and selection. This distinction requires a notion of fitness as a pairwise comparison between individuals taken two at a time, and so vitiates the interpretation (...) of the theory as one about populations exclusively.

Identifies and explores the core philosophical issues in social work, such as political, moral, and logical issues and speculates about their relevance to practice.

Despite growing evidence that a significant number of patients living with Parkison’s disease experience neuropsychiatric changes following Deep Brain Stimulation treatment, the phenomenon remains poorly understood and largely unexplored in the literature. To shed new light on this phenomenon, we used qualitative methods grounded in phenomenology to conduct in-depth, semi-structured interviews with 17 patients living with Parkinson’s Disease who had undergone DBS. Our study found that patients appear to experience postoperative DBS-induced changes in the form of self-estrangement. Using the insights (...) from patients’ subjective perceptions of postoperative self-change provides a potent explanation of potential DBS-induced self-estrangement. (shrink)

From an evolutionary perspective, both atavism and somatic evolution/convergent evolution theories can account for the consistent occurrence, and astounding attributes of cancers: being able to evolve from a single cell to a complex organized system, and malignant transformations showing significant similarities across organs, individuals, and species. Here, we first provide an overview of these two hypotheses, including the possibility of them not being mutually exclusive, but rather potentially representing the two extremes of a continuum in which the diversity of cancers (...) can emerge. In reviewing the current literature, we also discuss the criteria that should be applied to discriminate between the two competing theories and to determine their relevant contributions to oncogenesis and cancer progression. Finally, we deliberate on the potential applications of this conceptual framework in developing novel treatment strategies. (shrink)

Michel Henry has renewed our understanding of life as immanent affectivity: life cannot be reduced to what can be made visible; it is – as immanent and as affectivity – radically invisible. However, if life (la vie) is radically immanent, the living (le vivant ) has nonetheless to relate to the world: it has to exist . But, since existence requires and includes intentional components, human reality – being both living and existing – implies that immanence and intentionality be related (...) to one another, even though they are conceived at the same time as radically distinct modes of appearing in Henry’s phenomenology of life. Following this line of thought, we are faced with at least two questions: First, what reality does immanent appearing have for us as existing and intentional beings? And second, from an ethical point of view, what does Henry’s opposition of “barbarism” and “second birth” mean in terms of existence? As will be shown, it follows from the standpoint of radical phenomenology itself that immanent affectivity has reality for us only insofar as it finds its expression or translation in the realm of the intentionally visible and that, with regard to ethics, both “barbarism” and its overcoming in “second birth” are effective only insofar as they are mediated through representations. Henry’s critique of representation and intentionality needs therefore to be revised, especially in the field of practical philosophy, where the essential role played by intentionality has to be acknowledged even by radical phenomenology.

The goal of this article is to shed light on Deep Brain Stimulation (DBS) postoperative suicidality risk factors within Treatment Resistant Depression (TRD) patients, in particular by focusing on the ethical concern of enrolling patient with history of self-estrangement, suicide attempts and impulsive–aggressive inclinations. In order to illustrate these ethical issues we report and review a clinical case associated with postoperative feelings of self-estrangement, self-harm behaviours and suicide attempt leading to the removal of DBS devices. Could prospectively identifying and excluding (...) patients with suicidality risk factors from DBS experimental trials—such as history of self-estrangement, suicide attempts and impulsive–aggressive inclinations—lead to minimizing the risk of suicidality harm?

The dominant position of science in our culture has ended. In our postmodern world, belief that science will provide the answer to our problems and that progress is inevitable has been shaken, if not toppled. Optimism has been replaced by realism, creating a milieu for the development of intelligent Christian belief. Participating in the Trinity Institute's conference on ÒThe Church in a Postmodern Age, these six prominent scholars explore the breakdown of the basic tenets of the Enlightenment, the sorry state (...) of biblical literacy in our culture, Christian faith in a pluralistic world, the relevance of the Bible today, and the role of the church in our age.
