The concept of an attractor in a mathematical dynamical system is reviewed. Emphasis is placed on the distinction between a cell assembly, the corresponding attractor, and the attractor dynamics. The biological significance of these entities is discussed, especially the question of whether the representation of the stimulus requires the full attractor dynamics, or merely the cell assembly as a set of reverberating neurons. Comparison is made to Freeman's study of dynamic patterns in olfaction.

Most discussions of the use of race and ethnicity in biomedical research and clinical care focus on broad national and transnational populations. Looking at the problem from the perspective of large populations, however, misses the rest of a continuum that runs from the global human population to local communities. If race and ethnicity are fundamental categories for biomedical analyses, they should be informative at all points along that continuum, much as the definition of a gene remains unchanged whether analyzed in (...) the context of an individual, a group, or the total human population. By examining the utility of racial and ethnic categories at a local community level, we can better evaluate whether those categories are indeed fundamental units for analysis. Alternatively, these categories may be analytic proxies useful primarily for approximating aggregate biological and social features of large populations at national and transnational levels of analysis.

Lost in the debate over the use of racial and ethnic categories in biomedical research is community-level analysis of how these categories function and influence health. Such analysis offers a powerful critique of national and transnational categories usually used in biomedical research such as “African-American” and “Native American.” Ethnographic research on local African-American and Native American communities in Oklahoma shows the importance of community-level analysis. Local health practices tend to be shared by members of an everyday interactional community without regard (...) to racial or ethnic identity. Externally created practices tend to be based on the existence of externally-imposed racial or ethnic identities, but African-American and Native American community members show similar patterns in their use of extra-community practices. Thus, membership in an interactional community seems more important than externallyimposed racial or ethnic identity in determining local health practices, while class may be as or more important in accounting for extra-community practices.

Research on human genetic variation can present collective risks to all members of a socially identifiable group. Research that associates race or ethnicity with a genetic disposition to disease, for example, presents risks of group discrimination and stigmatization. To better protect against these risks, some have proposed supplemental community-based reviews of research on genetic differences between populations. The assumption behind these appeals is that involving members of study populations in the review process can help to identify and minimize collective risks (...) that otherwise could go unnoticed. In contrast to this position, critics have argued that supplemental community-based reviews are unnecessary, impractical, and morally problematic. This paper is our attempt to advance this debate by distinguishing the various goals of community review and the forms that it can take. (shrink)

Strategies for protecting historically disadvantaged groups have been extensively debated in the context of genetic variation research, making this a useful starting point in examining the protection of social groups from harm resulting from biomedical research. We analyze research practices developed in response to concerns about the involvement of indigenous communities in studies of genetic variation and consider their potential application in other contexts. We highlight several conceptual ambiguities and practical challenges associated with the protection of group interests and argue (...) that protectionist strategies developed in the context of genetic research will not be easily adapted to other types of research in which social groups are placed at risk. We suggest that it is this set of conceptual and practical issues that philosophers, ethicists, and others should focus on in their efforts to protect identifiable social groups from harm resulting from biomedical research.

The mechanism of stellar aberration was explained and formulated by Bradley in terms of the existence of a unique reference frame for light propagation. However, Einstein's denial of the existence of such a frame appears to undermine Bradley's interpretation of the phenomenon. It is suggested that the recent evidence for a cosmologically-based inertial reference frame provides a new physical basis for Bradley's explanation in a manner consistent with the requirements of special relativity. It is shown that a “delay” effect is (...) also involved in our observation of the direction of nearby sources, and that the aberration and delay effects exactly compensate for nearby sources comoving with a terrestrial observer.

Philosophy, according to a prominent conception of its nature and method, consists primarily of conceptual or linguistic analysis. Because the relations between concepts are logical, and because the propositions which express them are necessary, philosophy is taken to be an a priori activity.

Foundations of the theory of signs.--Signs, language, and behavior.--Five semiotical studies.

For several decades, Dr. Morris has worked primarily with twoproblems: the development of a general theory of signs, and thedevelopment of a general theory of value. He approached both problemsin terms of George Mead's theory of action or behavior. This bookbrings together these two lines of development. For several decades, Dr. Morris has worked primarily with two problems: the development of a general theory of signs, and the development of a general theory of value. He approached both problems (...) in terms of George Mead's theory of action or behavior. This book brings together these two lines of development. In many languages there is a term like the English "meaning" which has two poles: that which something signifies and the value or significance of what is signified. The nature of signification and significance, as well as their relations within human behavior, is the subject matter of this book. This book is addressed to philosophers and to students of the behavioral sciences, but it will also appeal to anyone seriously interested in the study of human communication. (shrink)

This book reflects on the variety of ways in which mourning affects political and social life. Through the narrative of the contributors, the book demonstrates how mourning is intertwined with politics and how politics involves a struggle over which losses and whose lives can, or should, be mourned.

On the Edge of Anarchy completes A. John Simmons's exploration and development of Lockean moral and political philosophy, a project begun in The Lockean Theory of Rights (Princeton, 1992). In this new book, Simmons discusses the Lockean view of the nature of, grounds for, and limits on political relations between persons. Locke's ideas on this topic are probably the most influential in the history of political thought, but their philosophical virtues and implications have remained largely unappreciated. Here Simmons remedies this (...) situation by treating Locke as a philosopher, rather than as a theologian or an activist writing rhetorical political tracts. Locke's works emerge not as episodes in the history of ideas but as bodies of arguments addressing the same questions as contemporary philosophy. This book pursues the issues Locke raises far beyond the boundaries of his own texts and theories. By criticizing, streamlining, and developing Locke's views, Simmons elaborates a powerful Lockean political philosophy with strongly anarchistic implications. On the Edge of Anarchy will interest not only Locke specialists and political philosophers, but also students and professionals in philosophy, government, and law - and all others who are interested in the foundational political principles embraced and celebrated by Anglo-American societies.

Research with predominately minority, urban students has documented an educational “gender gap,” where girls tend to be more likely to go to college, make higher grades, and aspire to higher status occupations than boys. We know less, however, about inequality, gender, and schooling in rural contexts. Does a similar gap emerge among the rural poor? How does gender shape the educational experiences of rural students? This article explores these questions by drawing on participant observation and student interviews at a predominately (...) white and low-income rural high school. I find a substantial gap favoring girls in this context, and I analyze how understandings of masculinity shaped schooling using the theory of hegemonic masculinity. The findings suggest that boys' underachievement is actually rooted in masculine dominance and related to particular constructions of gender and social class. (shrink)

What are preferences and are they reasons for action? Is it rational to cooperate with others even if that entails acting against one's preferences? The dominant position in philosophy on the topic of practical rationality is that one acts so as to maximize the satisfaction of one's preferences. This view is most closely associated with the work of David Gauthier, and in this collection of essays some of the most innovative philosophers working in this field explore the controversies surrounding Gauthier's (...) position. Several essays argue against influential conceptions of preference, while others suggest that received conceptions of rational action misidentify the normative significance of rules and practices. This collection will be of particular interest to philosophers of social theory and to reflective social scientists in such fields as economics, political science and psychology. (shrink)

When any man, even in political society, renders himself by his crimes obnoxious to the public, he is punished by the laws in his goods and person; that is, the ordinary rules of justice are, with regard to him, suspended for a moment, and it becomes equitable to inflict on him, for the benefit of society, what otherwise he could not suffer without wrong or injury?

Amartya Sen was awarded the Nobel Memorial Prize in Economics in 1998 'for his contributions in welfare economics'. Although his primary academic appointments have been mostly in economics, Sen is also an important and influential social theorist and philosopher. His work on social choice theory is seminal, and his writings on poverty, famine, and development, as well his contributions to moral and political philosophy, are important and influential. Sen's views about the nature and primacy of liberty also make him a (...) major contemporary liberal thinker. This volume of essays on aspects of Sen's work is aimed at a broad audience of readers interested in social theory, political philosophy, ethics, public policy, welfare economics, the theory of rational choice, poverty, and development. Written by a team of well-known experts, each chapter provides an overview of Sen's work in a particular area and a critical assessment of his contributions to the field. (shrink)
