Heteroblastic development is often observed in Cormophytae, but it can also be characterized in Thallophytae as shown by the detailed investigation of the development of the algaAntithamnion plumula (Ceramiaceae, Rhodophyta). In this species, heteroblasty concerns (i) dimensional variables (such as pleuridia length and lateral cladome first tagma length) and (ii) variables that characterize the cell growth kinetics (main axis cells). Apex curvature also varies during ontogenesis.The generality of the property in plants led to search for its origin: apical meristem own (...) dynamics, ontogenetic evolution of internal relationships, dialectical relationships between the plant and its environment.

À l'heure où tant de discours prônent des sociétés dites 'inclusives,' dans nos vies quotidiennes, la vulnérabilité est encore trop souvent perçue comme le versant négatif de l'autonomie, un moment de l'existence qu'il faut impérativement dépasser pour pouvoir construire l'identité d'un sujet libre et autonome. Et si, à l'inverse, la construction d'une identité forte ne pouvait advenir que grâce à l'articulation entre vulnérabilité, comme condition normale de l'existence, et autonomie? Fruit d'un travail collectif, cet ouvrage souhaite prouver, à l'aide de (...) la pensée de philosophes comme Paul Ricoeur, Emmanuel Levinas, Michel Henry, Martha Nussbaum ou encore Platon et Aristote, comment le déni de la vulnérabilité, bien que compréhensible, peut devenir "toxique" lorsqu'il n'est pas démasqué. Cela aussi bien pour l'individu que pour la société. Un livre qui croise de multiples regards, la philosophie, le droit, les sciences de la santé, la politique, pour éclairer la façon dont nos modes de vie et l'organisation de nos sociétés pourraient changer, y compris d'un point de vue pratique, si vulnérabilité et autonomie étaient considérées comme des moments indispensables et complémentaires du développement de l'identité du sujet."--Back cover.

What processes underlie the formation of new memories? What determines their strength? Where are the changes underlying memory located? With contributions from leading experts, this book offers the most up-to-date attempts to answer these and many more critical questions.

Both the theoretical frameworks that organize the first part of Barbey & Sloman's (B&S's) target article and the empirical evidence marshaled in the second part are marked by distinctions that should not exist (i.e., false dichotomies), conflations where distinctions should be made, and selective omissions of empirical results that create illusions of theoretical and empirical favor.

Smith's well-crafted narrative contributes substantially to revealing the moral and political intentions "at the core" of the Ethics . Its focus is the role and (...) possibility of freedom in Spinoza's metaphysics, based on Smith's thesis that a version of teleological eudaemonism and democratic politics are the principal themes of the Ethics. Indeed, Smith considers the Ethics a "founding document of . . . democratic individualism" . He places Spinoza in his Enlightenment context, building on known.. (shrink)

A more complete and balanced theoretical framework for social psychology, as recommended in the target article, must include functional explanations of processes – moving beyond enumerations of processes and their properties. These functional explanations are at a different, but complementary, level from process descriptions. The further advancement of social psychology relies on the incorporation of such multilevel explanations.

Plants are considered as archetypes of the ramification phenomenon but numerous elementary processes occur in the elaboration of the shaping of each species. This paper aims to identify the part ascribed to different mechanisms in the morphogenesis of a Thallophyte, the red alga Antihamnion plumula.Agonistic-antagonistic models (Bernard-Weil, 1988) can be applied to this alga whose thallus includes two different kinds of whorls, pleuridian and cladomian. In each whorl the agonistic and antagonistic effects are expressed by the full development (S) of (...) the two branches and by their symmetry rate (R) respectively. Variations in S and R show the existence of particular pleuridian whorls having an intermediary dissymmetry and a rhythmic arrangement similarly to that of the cladomian whorls. A unilateral change of the system (removal of a lateral cladome) induces a transitory destabilisation mainly manifested by the stimulating ascendant flow throughout the thallus. (shrink)

The filamentous and branched thallus of Antithamnion plumula is constitued of two different kinds of branches with apical growth: the cladomial axes with a continuous or indefinite growth, and the pleuridia with a limited growth. The size of the pleuridia depends on their position with respect to the lateral cladomial axes.The growth kinetics of 35 pleuridia were analysed using Nelder's generalized logistics. Each sigmoidal curve, which was divided into four growth stages from the instantaneous acceleration variations, was thus characterized by (...) ten kinetic parameters: lengths at the time of the changes in growth stage, durations of the growth stages and maximum growth rate.

The paper by Bergnar and Bunford in this edition of Philosophy, Psychiatry, & Psychology is a sophisticated examination of a central question that has lacked consensus in the philosophy of psychiatry, namely, what is “the key aspect of the meaning of this fundamental term, mental disorder”? To settle this question, the authors use an empirical approach by surveying graduate students in clinical psychology. In this way, they attempt to invoke the Wittgensteinian method of determining the meaning of a term by (...) seeing how it is used. The empirical results, the authors argue, serve as strong evidence in support of the position that the term ‘mental disorder’ designates disability... (shrink)

Agricultural biotechnology refers to a diverse set of industrial techniques used to produce genetically modified foods. Genetically modified foods are foods manipulated at the molecular level to enhance their value to farmers and consumers. This book is a collection of essays on the ethical dimensions of ag biotech. The essays were written over a dozen years, beginning in 1988.

Most people care about animals, but only a tiny fraction are vegan. The rest often think of veganism as an extreme position. They certainly do not believe that they have a moral obligation to become vegan. Gary L. Francione—the leading and most provocative scholar of animal rights theory and law—demonstrates that veganism is a moral imperative and a matter of justice. He shows that there is a contradiction in thinking that animals matter morally if one is also not vegan, (...) and he explains why this belief should logically lead all who hold it to veganism. Francione dismantles the conventional wisdom that it is acceptable to use and kill animals as long as we do so “humanely.” He argues that if animals matter morally, they must have the right not to be used as property. That means that we cannot eat them, wear them, use them, or otherwise treat them as resources or commodities. Why Veganism Matters presents the case for the personhood of nonhuman animals and for veganism in a clear and accessible way that does not require any philosophical or legal background. This book offers a persuasive and powerful argument for all readers who care about animals but are not sure whether they have a moral obligation to be vegan. (shrink)

The empirical diagnosis presented in this paper is based on interviews with nurse practitioners and physicians designed to elicit their perceptions of the nature and role of ethical dilemmas in clinical practice. Having selected five of these perceptions or views which were common and significant. the philosophical therapy offered consists in, first, a general discussion of ethical dilemmas, and second, a critical analysis of each of the five views with the aim of pointing out confusions and errors, the recognition of (...) which can be of applied and practical help in the clinical setting.

I worked for many years constructing my version of the global case but, as I continued to try to strengthen it, I slowly began to lose confidence. My unease began with several personal experiences. One of our children had a common but annoying physical ailment, for which our pediatrician prescribed a very expensive nasal spray. When I inquired about its cost, the pharmacist informed me that it was a new, genetically engineered, product. The spray worked, and Karen and I never (...) batted an eye. (shrink)

Discourse about the use of animals in biomedical research usually focuses on two issues. The first, which I will refer to as the “necessity issue,” is empirical and asks whether the use of nonhumans in experiments is required in order to gather statistically valid information that will contribute in a significant way to improving human health. The second, which I will refer to as the “justification issue,” is moral and asks whether the use of nonhumans in biomedical research, if necessary (...) as an empirical matter, can be defended as a matter of ethical theory.If it is not necessary as an empirical matter to use animals in research, then there is no need to inquire about moral justification. Therefore, I examine the necessity issue first. The argument that it is necessary to use nonhumans in biomedical research, though flawed, is at least plausible, unlike our necessity arguments for other animal uses. I then discuss the justification issue and conclude that we cannot morally justify using nonhuman animals in research. (shrink)
