Stem cells and their malignant counterparts require the support of a specific microenvironment or “niche”. While various anti‐cancer therapies have been broadly successful, there are growing opportunities to target the environment in which these cells reside to further improve therapeutic efficacy and outcome. This is particularly true when the aim is to target normal or malignant stem cells. The field aiming to target or use the niches that harbor, protect, and support stem cells could be designated as “nichotherapy”. In this (...) essay, we provide a few examples of nichotherapies. Some have been employed for decades, such as hematopoietic stem cell mobilization, whereas others are emerging, such as chemosensitization of leukemia stem cells by targeting their niche. (shrink)

Quand le gouvernement de René Lévesque mit fin au financement occulte des partis politiques en 1977, les démocrates de tous les horizons se mirent à croire qu’il était possible d’éliminer la corruption systémique qui gangrène la vie publique partout dans le monde. Pendant un temps, on a cru que le Québec était devenu un havre unique d’intégrité avec son financement populaire des partis, ses limites de contributions, ses règles de transparence, auxquels on avait ajouté des normes sévères dans l’octroi des (...) contrats publics d’achats de biens et services. Ce paradis terrestre de la pureté politique n’a malheureusement pas duré longtemps et nous savons aujourd’hui que les assoiffés de pouvoir et d’argent gravitant dans et autour des formations politiques ont rapidement décelé les failles de la nouvelle Loi et se sont immédiatement organisés pour la contourner. Leurs stratagèmes se sont déployés pendant une trentaine d’années en toute impunité intoxiquant toutefois, il faut le dire, certains plus que d’autres. Heureusement, ces combines ont fini par être mises au jour et devenir objet d’intérêt prioritaire de la population, obligeant ainsi l’Assemblée nationale à refaire ses devoirs. (shrink)

L'espere humaine est conflictuelle et gregaire, menacee de toutes parts par la montee aux extremes de la violence. Aussi se trouve-t-elle confrontee a ce probleme urgent: comment vivre ensemble sans s'entre-tuer? Le politique est l'ordre humain en charge de ce probleme, et son objectif est la paix par la justice. Dans ce bref precis didactique, Jean Baechler prouve que le seul moyen d'eviter la guerre et de resoudre des problemes communs dans un monde dangereux et imprevisible est de s'efforcer (...) a l'union politique, meme si celle-ci est bien evidemment extremement difficile a realiser.

This paper explores principles governing the rational balance among an agent's beliefs, goals, actions, and intentions. Such principles provide specifications for artificial agents, and approximate a theory of human action (as philosophers use the term). By making explicit the conditions under which an agent can drop his goals, i.e., by specifying how the agent is committed to his goals, the formalism captures a number of important properties of intention. Specifically, the formalism provides analyses for Bratman's three characteristic functional roles played (...) by intentions [7, 9], and shows how agents can avoid intending all the foreseen side-effects of what they actually intend. Finally, the analysis shows how intentions can be adopted relative to a background of relevant beliefs and other intentions or goals. By relativizing one agent's intentions in terms of beliefs about another agent's intentions (or beliefs'), we derive a preliminary account of interpersonal commitments. (shrink)

What is involved when a group of agents decide to do something together? Joint action by a team appears to involve more than just the union of simultaneous individual actions, even when those actions are coordinated. We would not say that there is any teamwork involved in ordinary automobile traffic, even though the drivers act simultaneously and are coordinated (one hopes) by the traffic signs and rules of the road. But when a group of drivers decide to do something together, (...) such as driving somewhere as a convoy, it appears that the group acts more like a single agent with beliefs, goals, and intentions of its own, over and above the individual ones.

A central problem in applying logical knowledge representation formalisms to traditional robotics is that the treatment of belief change is categorical in the former, while probabilistic in the latter. A typical example is the fundamental capability of localization where a robot uses its noisy sensors to situate itself in a dynamic world. Domain designers are then left with the rather unfortunate task of abstracting probabilistic sensors in terms of categorical ones, or more drastically, completely abandoning the inner workings of sensors (...) to black-box probabilistic tools and then interpreting their outputs in an abstract way. Building on a first-principles approach by Bacchus, Halpern and Levesque, and a recent continuous extension to it by Belle and Levesque, we provide an axiomatization that shows how localization can be realized wrt a basic action theory, thereby demonstrating how such capabilities can be enabled in a single logical framework. We then show how the framework can also enable localization for multiple agents, where an agent can appeal to the sensing already performed by another agent and the knowledge of their relative positions to localize itself.

The concept of joint action is at the core of numerous diverse research topics, including philosophical explorations of social action, studies of human dialogue, human-computer interaction, computer-supported collaborative work, multiagent systems, distributed artificial intelligence, distributed simulation, and contract law. It is therefore remarkable that so central a concept has received so little detailed analysis, in comparison with studies of individuals. However, in recent years, the study of joint action has begun to undergo more intense scrutiny, primarily from philosophers and researchers (...) in artificial intelligence. These two disciplines often address similar topics but with different motivations, methodologies, tools, and criteria for success. Although this paper is inspired by philosophical work, it is squarely motivated by the concerns of building intelligent systems that are capable of collaborative behavior, either with a user, or with other such systems. Still, we hope that the paper sheds light on philosophical issues, and treats the subject of joint action at a sufficiently precise level to be illuminating of problems that any philosophical account needs to confront.

Dans les sociétés démocratiques contemporaines, les individus revendiquent le droit d'aimer librement. Ils sont attachés à la réussite de leur vie sentimentale et à l'épanouissement de leur sexualité. Mais le corps épris nous permet-il d'accéder à l'existence heureuse que nous désirons? Dans ce livre, Jean-Marie Frey met au jour les ressorts de l'inquiétude suscitée par l'amour charnel. Il montre comment la pudibonderie et le libertinage expriment, chacun à leur manière, une tentative pour se rassurer. Les prudes désireux de voiler (...) les femmes et les libertins exhibant un corps morcelé dans l'imagerie pornographique, n'éprouvent-ils pas les uns et les autres une crainte devant la chair désirable? L'auteur oppose les figures du pudibond et du libertin à celle d'un amant disposé à jouer le jeu d'une passion amoureuse à la fois inquiétante et joyeuse. (shrink)

The aim of this study is to challenge the current scholarly consensus depicting Plato as having renounced the political ideal of his Republic, and modified it in favour of a in his last work, the Laws. The study shows that Plato's critique of democracy remains as firm in the Laws as it was in the Republic and the Statesman, refusing to concede any room to any form of popular sovereignty that could threaten the government of knowledge.

Along with Husserl's Ideas and Heidegger's Being and Time, Being Given is one of the classic works of phenomenology in the twentieth century. Through readings of Kant, Husserl, Heidegger, Derrida, and twentieth-century French phenomenology (e.g., Merleau-Ponty, Levinas, and Henry), it ventures a bold and decisive reappraisal of phenomenology and its possibilities. Its author's most original work to date, the book pushes phenomenology to its limits in an attempt to redefine and recover the phenomenological ideal, which the author argues has never (...) been realized in any of the historical phenomenologies. Against Husserl's reduction to consciousness and Heidegger's reduction to Dasein, the author proposes a third reduction to givenness, wherein phenomena appear unconditionally and show themselves from themselves at their own initiative. Being Given is the clearest, most systematic response to questions that have occupied its author for the better part of two decades. The book articulates a powerful set of concepts that should provoke new research in philosophy, religion, and art, as well as at the intersection of these disciplines. Some of the significant issues it treats include the phenomenological definition of the phenomenon, the redefinition of the gift in terms not of economy but of givenness, the nature of saturated phenomena, and the question “Who comes after the subject?” Throughout his consideration of these issues, the author carefully notes their significance for the increasingly popular fields of religious studies and philosophy of religion. Being Given is therefore indispensable reading for anyone interested in the question of the relation between the phenomenological and the theological in Marion and emergent French phenomenology.

Available Again! Long before the "shock and awe" campaign against Iraq in March 2003, debates swarmed around the justifications of the U.S.-led war to depose Saddam Hussein. While George W. Bush's administration declared a just war of necessity, opponents charged that it was a war of choice, and even opportunism. Behind the rhetoric lie vital questions: when is war just, and what means are acceptable even in the course of a just war? Originally published in 1991, in the wake of (...) the first war against Iraq, Just War Theory explores this essential dilemma. With a new preface by the editor, the essays in this indispensable collection move beyond the theoretical origins of just war theory to examine issues faced by military strategists, politicians, social theorists, and anyone concerned with the provocations and costs of military action. Popular wisdom once claimed that notions of just war would become obsolete with the onset of "total warfare," characterized by attacks on civilians and undiscriminating weapons of mass destruction. While the last decade has been ripe with brutality, just war theory is more critical than ever to the future of international relations and public discourse. This readable collection is an invaluable introduction to the debate. (shrink)

A 62-year-old female with Huntington’s disease presented after a suicide attempt. Her advance directive stated that she did not want intubation or resuscitation, which her family acknowledged and supported. Despite these directives, she was resuscitated in the emergency department and continued to state that she would attempt suicide again. Her suicidality in the face of a chronic and advancing illness, and her prolonged consistency in her desire to take her own life, left careproviders wondering how to provide ethical, respectful care (...) to this patient. Tension between the ethical principles of autonomy and beneficence is central in this case. The patient’s narrative demonstrated that her suicide was an autonomous decision, free from coercion or disordered thinking from mental illness. Beneficence then would seem to necessitate care aligned with the patient’s desire to end her life, which created ethical uneasiness for her family and careproviders. The case highlights several end-of-life ethical considerations that have received much recent attention. With ongoing discussions about the legalization of aid in dying across the country, caregivers are challenged to understand what beneficence means in people with terminal illnesses who want a say in their death. This case also highlights the profound moral distress of families and careproviders that arises in such ethically challenging scenarios. (shrink)

In 2016, the Colorado legislature passed an amendment to Colorado’s medical proxy law that established a process for the appointment of a physician to act as proxy decision maker of last resort for an unrepresented patient (Colorado HB 16-1101: Medical Decisions For Unrepresented Patients). The legislative process brought together a diverse set of stakeholders, not all of whom supported the legislation. Following passage of the statutory amendment, the Colorado Collaborative for Unrepresented Patients (CCUP), a group of advocates responsible for initiating (...) the legislative process, coordinated a unique effort to engage these stakeholders in the creation of a set of voluntary guidelines to assist facilities and individual careproviders in the implementation of policies and procedures enabled by the statute. This article delineates the questions and concerns of stakeholders, describes how those issues were addressed within the guidelines, and proposes additional opportunities for research to assess the impact of the legislation in Colorado.

La philosophie ne se réduit pas à la pure réflexion ni à la quête d'une sagesse intemporelle. Elle est aussi invention ou création de concepts. Elle s'expose volontiers à traverser le cours des sciences, à inscrire son histoire dans le contrepoint de leurs développements. Quand il se veut ainsi passeur de savoirs, le philosophe expérimente des concepts qui filtrent des interprétations, établissent des relations inattendues, modifient des approches trop abstraites : le temps, l'infini, la matière, le cosmos. L'enquête astrophysique ou (...) les recherches sur le cerveau offrent autant d'occasions de mises en perspective propices à la pédagogie que d'invitations à reconstituer le tissu des idées qui fondent la culture et les idéaux de nos sociétés. Même s'il analyse parfois des méthodes et des paradigmes scientifiques, ce livre ne relève pas de la philosophie des sciences telle que l'Université en définit la discipline. Il entend surtout questionner les conceptions scientifiques du monde qui justifient, transforment ou bouleversent nos croyances, nos comportements et aussi nos décisions. Il témoigne que les seuls savoirs qui vaillent sont toujours déconcertants. (shrink)

Truth and Existence , written in response to Martin Heidegger's Essence of Truth , is a product of the years when Sartre was reaching full stature as a philosopher, novelist, playwright, essayist, and political activist. This concise and engaging text not only presents Sartre's ontology of truth but also addresses the key moral questions of freedom, action, and bad faith. Truth and Existence is introduced by an extended biographical, historical, and analytical essay by Ronald Aronson. " Truth and Existence is (...) another important element in the recently published links between Sartre's existentialist ontology and his later ethical, political, and literary concerns. . . . The excellent introduction by Aronson will help readers not experienced in reading Sartre."-- Choice "Accompanied by an excellent introduction, this dense, lucidly translated treatise reveals Sartre as a characteristically 20th-century figure."-- Publishers Weekly Jean-Paul Sartre (1906-1980) was offered, but declined, the Nobel Prize for literature in 1964. His many works of fiction, drama, and philosophy include the monumental study of Flaubert, The Family Idiot , and The Freud Scenario , both published in translation by the University of Chicago Press.

One of the strongest strands in Nancy's philosophy is an attempt to rethink community and the very idea of the social in a way that does not ground these ideas in some individual subject or subjectivity. The fundamental argument of this book is that being is always 'being with', that 'I' is not prior to 'we', that existence is essentially co-existence. He thinks this being together, not as a comfortable enclosure in a pre-existing group, but as a mutual abandonment and (...) exposure to each other, one that would preserve the 'I' and its freedom in a mode of imagining community as neither a 'society of spectacle' nor via some form of 'authenticity'.

Qu'est-ce que la connaissance? Que pouvons-nous connaître? Et comment connaissons-nous? Ces questions philosophiques classiques relèvent de l'épistémologie, qui excède largement l'histoire philosophique des sciences à laquelle elle se trouve trop souvent réduite. Attentif aux enseignements des sciences de la cognition comme aux exigences normatives de la connaissance, le présent volume introduit aux questions les plus débattues de l'épistémologie contemporaine de façon nouvelle et accessible. Ses chapitres ont été rédigés par une nouvelle génération de philosophes francophones dont les recherches s'inscrivent résolument (...) dans les débats internationaux les plus vifs. Que connaissons-nous grâce à nos sens? Quelle confiance accorder à la perception? A la mémoire? Au témoignage? Raisonner nous permet-il d'élargir le domaine de nos connaissances? Est-il possible d'étendre nos capacités cognitives? L'art et les émotions sont-ils des outils de connaissance à part entière? La connaissance de soi est-elle d'un genre particulier? Que pourrions-nous savoir de Dieu? Qu'est-il possible de connaître a priori? A quelles conditions nos jugements sont-ils justifiés? Y a-t-il des normes de la croyance et de l'enquête? Telles sont les questions épistémologiques fondamentales auxquelles ce livre est consacré. (shrink)

Jean Piaget was one of the most salient and inspirational figures in psychological and educational research this century. He was prolific, authoring or editing over eighty books and numerous journal papers which have spawned a huge and fertile continuation of his research over the decades. A major component of any course on children's psychological development and a research tradition that is expanding, scholars need access to the original texts rather than relying on secondhand accounts. Jean Piaget: Selected Works (...) is a chance to acquire key original texts, most of which have been previously unavailable for several years. (shrink)

"Christian philosophy" is commonly regarded as an oxymoron, philosophy being thought incompatible with the assumptions and conclusions required by religious faith. According to this way of thinking, philosophy and theology must forever remain distinct. In From Theology to Theological Thinking, Jean-Yves Lacoste takes a different approach. Stepping back from contemporary philosophical concerns, Lacoste--a leading figure in the philosophy of religion--looks at the relationship between philosophy and theology from the standpoint of the history of ideas. He notes in particular that (...) theology and philosophy were not considered separate realms until the high Middle Ages, this distinction being a hallmark of the modern era that is coming to an end. Lacoste argues that the intellectual task before us now is to work in the frontier region between or beyond these domains, work he identifies as "the task of thinking." With this argument, Lacoste resets our understanding of Western Christian thought, contending that a new way of thinking that is at once philosophical and theological will be the lasting discourse of Christianity.

This paper describes an approach for reasoning in a dynamic domain with nondeterministic actions in which an agent’s beliefs correspond to the simplest, or most plausible, course of events consistent with the agent’s observations and beliefs. The account is based on an epistemic extension of the situation calculus, a first-order theory of reasoning about action that accommodates sensing actions. In particular, the account is based on a qualitative theory of nondeterminism. Our position is that for commonsense reasoning, the world is (...) most usefully regarded as deterministic, and that nondeterminism is an epistemic phenomenon, arising from an agent’s limited awareness and perception. The account offers several advantages: an agent has a set of categorical beliefs, yet can deal with equally-likely outcomes or with outcomes of differing plausibility. The agent maintains as its set of contingent beliefs the most plausible, or simplest, picture of the world, consistent with its beliefs and actions it believes it executed; yet it may modify these in light of later information.
