According to the prevailing paradigm in social-cognitive neuroscience, the mental states of individuals become shared when they adapt to each other in the pursuit of a shared goal. We challenge this view by proposing an alternative approach to the cognitive foundations of social interactions. The central claim of this paper is that social cognition concerns the graded and dynamic process of alignment of individual minds, even in the absence of a shared goal. When individuals reciprocally exchange information about each other's (...) minds processes of alignment unfold over time and across space, creating a social interaction. Not all cases of joint action involve such reciprocal exchange of information. To understand the nature of social interactions, then, we propose that attention should be focused on the manner in which people align words and thoughts, bodily postures and movements, in order to take one another into account and to make full use of socially relevant information.

As Van Dijk proposed in the first issue of Discourse and Communication, the main purpose of this journal is to bridge the two cross-disciplines of communication and discourse studies. Given this goal, this article sought to help clear the ground for such interdisciplinary development by investigating how organizational researchers use the terms `discourse' and `communication' and cast discourse—communication relationships. By reviewing 112 organizational discourse studies from major journals in communication, organizational studies, and interdisciplinary journals published between 1981 and 2006, this (...) study identified diverse conceptualizations of these basic concepts. The findings help dispel some of the misunderstandings that scholars from one research field may possess toward the other and sort through some, if not all, the confusions regarding the terms `discourse', `communication', and their relationships.

It is claimed by the future like ours anti-abortion argument that since killing adult humans is wrong because it deprives them of a future of value and the fetus has a future of value, killing fetuses is wrong in the same way that killing adult human beings is wrong. In The morality of abortion and the deprivation of futures (this journal, April 2000) I argued that the persuasive power of this argument rests upon an equivocation on the term “future of (...) value”. If the expression means “a potential future of value” then the moral claim is implausible because people do not in general have rights to what they need to fulfill their potential; if the expression means “self-represented future of value” then the argument fails because the fetus does not represent its future. Under no interpretation is the argument sound. In Deprivations, futures and the wrongness of killing (this journal, December 2001) Donald Marquis, author of the future like ours argument, responds at length to this objection. In the present essay the focus of the debate shifts to the proper interpretation of the right not to be killed. Donald Marquis argues that this liberty right entails the welfare right to the means necessary to sustain life; I argue that the right not to be killed does not entail unlimited welfare rights. On Marquis's view, the right not to be killed confers upon the fetus the right to whatever it takes to sustain life; on the view I defend, the right not to be killed does not confer upon the fetus or anyone else the right to another person's body. On Marquis's view, abortion is almost never permissible; on my view abortion is almost always permissible. (shrink)

In the first part, after a brief introduction to his academic biography, the leading role of Víctor Sánchez de Zavada in the introduction of formal linguistics in Spain is analysed and justified. His work as editor, professor, translator and writer is examined through his main publications. The second part of the paper is devoted to provide an analysis of the central hypotheses on which this theory of psychologicaI pragmatics is based. Furthermore, this second part examines his novel and global approach to linguistic activity, developed in his posthumous book Towards a psychological pragmatics. (shrink)

A unifying theory of general anesthetic-induced unconsciousness must explain the common mechanism through which various anesthetic agents produce unconsciousness. Functional-brain-imaging data obtained from 11 volunteers during general anesthesia showed specific suppression of regional thalamic and midbrain reticular formation activity across two different commonly used volatile agents. These findings are discussed in relation to findings from sleep neurophysiology and the implications of this work for consciousness research. It is hypothesized that the essential common neurophysiologic mechanism underlying anesthetic-induced unconsciousness is, as with (...) sleep-induced unconsciousness, a hyperpolarization block of thalamocortical neurons. A model of anesthetic-induced unconsciousness is introduced to explain how the plethora of effects anesthetics have on cellular functioning ultimately all converge on a single neuroanatomic/neurophysiologic system, thus providing for a unitary physiologic theory of narcosis related to consciousness.

This essay explores the claim that bioethics has become a mode of biopolitics. It seeks to illuminate one of the myriad of ways that bioethics joins other institutionalized discursive practices in the task of producing, organizing, and managing the bodies—of policing and controlling populations—in order to empower larger institutional agents. The focus of this analysis is the contemporary practice of transnational biomedical research. The analysis is catalyzed by the enormous transformation in the political economy of transnational research that has occurred (...) over the past three decades and the accompanying increase in the numbers of human bodies now subjected to research. This essay uses the work of Michel Foucault, particularly his notion of docile bodies, to analyze these changes. Two loci from the bioethics literature are explored—one treating research in the United States and one treating research in developing countries. In the latter, we see a novel dynamic of the new biopolitics: the ways in which bioethics helps to create docile political bodies that will police themselves and who will, in turn, facilitate the production of docile human bodies for research.

Within the moral/social order maintained and reproduced by biomedical ethics (i.e., the “peaceable community”), suffering is a senseless accident with no value. Insofar as suffering compromises the fundamental pillar of this order, namely, autonomy, it threatens the existence of the “peaceable community”. Consequently, biomedical ethics is only able to offer those who suffer one moral or practical response: that of elimination, embodied most vividly in the increasingly approved practice of assisted-suicide. Another moral/ social order, however, the “peaceable Kingdom” or the (...) “Body of Christ”, provides an alternative understanding of the meaning, purpose, and significance of suffering, through the Roman Catholic sacrament of anointing of the sick. Recognizing the power of sickness and suffering to “dis-inscribe” bodies of their normative self-understandings, the Church responds with a set of liturgical practices which intend to respond to the dynamics of suffering, re-inscribe these bodies, and assist persons in fulfilling the vocation of “participating in Christ's suffering for the salvation of the world”.

There is already a copious literature comparing Claudius' oration on the admission of the primores Galliae into the Roman Senate with Tacitus’ account of the speech and of the opposition's case in Annals 11. 23–4. Yet the Emperor's own purpose in speaking as he did still needs some illumination. Scholarly concentration on technical points about the citizenship, on Claudius’ antiquarianism and on his debt to Livy has been fruitful, but it has often distracted attention from Claudius’ immediate aim. Meanwhile, Tacitus’ (...) interpretation has been insidious in colouring our view of what course of action the imperial orator was trying to defend before the Senate. (shrink)

Cadaveric transplantation and living transplantation exist side by side. Both practices help to alleviate organ need. They provide us with two separate moral schemes. Is it rational to keep them apart? The cadaveric system is organised along strict, impartial lines, while the living system is inherently partial and local. The ethical justification for this partial scheme seems to be that it merely supplements the cadaveric scheme: partial transplants do not come at the expense of cadaveric impartiality, but in fact significantly (...) reduce the waiting time for patients on the list for a cadaveric transplant.This seemingly peaceful coexistence is challenged by new initiatives, among them living donation list exchange, and also the LifeSharers initiative, leading to practices that undermine cadaveric impartiality. Should we bemoan this fact, or should we move on towards a new balance in the relationship between cadaveric and living transplantation practices, towards a new moral weighing of impartial and partial values? I argue, against the background of a rapid growth of living donations, that we have good, ethical reasons—not only utilitarian ones—for giving the value of partiality a more prominent place in our policies.

In an influential essay entitled Why abortion is wrong, Donald Marquis argues that killing actual persons is wrong because it unjustly deprives victims of their future; that the fetus has a future similar in morally relevant respects to the future lost by competent adult homicide victims, and that, as consequence, abortion is justifiable only in the same circumstances in which killing competent adult human beings is justifiable.1 The metaphysical claim implicit in the first premise, that actual persons have a future (...) of value, is ambiguous. The Future Like Ours argument (FLO) would be valid if “future of value” were used consistently to mean either “potential future of value” or “self-represented future of value”, and FLO would be sound if one or the other interpretation supported both the moral claim and the metaphysical claim, but if, as I argue, any interpretation which makes the argument valid renders it unsound, then FLO must be rejected. Its apparent strength derives from equivocation on the concept of “a future of value”. (shrink)

One method for investigating the neurobiology of consciousness is to experimentally manipulate consciousness as a variable and then visualize the resultant functional brain changes with advanced imaging techniques. To begin investigation into this area, healthy volunteers underwent positron emission tomography scanning while listening to randomized word lists in both conscious and unconscious conditions. Following anaesthesia, subjects had no explicit memories. Nonetheless, subjects demonstrated implicit memory on a forced-choice test . These subsequent memory scores were correlated with regional brain metabolism measured (...) during encoding. Conscious recall and unconscious recognition memory demonstrated considerable anatomic overlap in correlating significantly with relative glucose metabolism in auditory verbal memory areas. However, only conscious recall correlated with mediodorsal thalamic nucleus activity; unconscious recognition memory did not. These findings suggest that conscious versus unconscious memory distinctions may depend on the presence or absence of correlated thalamic activity, and directly implicate the thalamus in the neurobiology of consciousness.
