This article presents a new set of analytical tools for understanding competing conceptions of political membership. Controversies concerning nationality and citizenship are often seen as products of conflict between `civic' and `ethnic' visions. However, the conceptual roots of current discussions and disagreements about political membership are actually more complicated than this might suggest. After examining the dichotomy of civic and ethnic and its limitations, this article identifies five competing ways of understanding the meaning of belonging to, or being a citizen (...) of, a given polity. Political membership may be understood and discussed as a matter of descent from common biological ancestors, cultural attachment, or identification with particular political principles. Alternatively, it may also be imagined either as an exchange of rights for duties or as a benefit granted to those contributing materially to the community. Each of these conceptions figures significantly in current political and intellectual discussions of citizenship and nationality. The typology may also prove applicable to new kinds of debates about global citizenship. (shrink)

This latest volume in the acclaimed Ruffin Series in Business Ethics brings together the contributions to the annual Ruffin Lecture series, in which some of the leading scholars in business ethics addressed the question: Can business, and business education, be considered one of the humanities, or is it in a class by itself? At a time when business is coming under attack for its apparent transgressions, this book iluminates the special values that inhere in the business world. Arguing all sides (...) of the issue, the distinguished contributors include Richard DeGeorge, Ronald Green, Thomas Dunfee, Robert Solomon, Edwin Hartman, Peter French, Patricia Werhane, Clarence Walton, W. Michael Hoffman, David Fedo, Kenneth Andrews, Joanne Ciulla, Manuel Velasquez, and George Brenkert. The editors contribute an informative Introduction and an Epilogue to set the debate in its proper context. (shrink)

We present a model of steady state solute and water reabsorption along the rat proximal tubule. Major co-and counter-transport systems in the apical and basolateral cell membranes are described using kinetic descriptions based on data from the flows and solute concentrations along the length of the proximal tubule as a function of filtration rate and peritubular solute concentrations. We show that for many aspects of proximal tubule transport physiology this kinetics-based model is an adequate representation of the mammalian proximal tubule.

The development of ethical guidelines and regulations regarding human subjects research has focused upon protection of vulnerable populations by relying on a limited typology of vulnerabilities. This results in several challenges: First, Institutional Review Boards struggle to interpret and apply the regulations because they are often vague and inconsistent. Second, applying the regulations to subjects who fit within multiple categories of vulnerability can lead to contradictions and the rejection of research that would be permissible if only one category were applicable. (...) Finally, some potential subjects have social and other context-based vulnerabilities that are not described in the federal regulations... (shrink)

Based on the proceedings of a 1985 conference held in the U.K., this volume embraces most of the important concerns in AI today, emphasizing common techniques and methodologies rather than applications. Topics covered include building efficient computational logic, planning and design, the representation of uncertain knowledge, user modelling, and psychological and philosophical issues. Papers on perception, theorem proving, expert systems, robotics, and data bases are also included. Each section is preceded by an introduction which draws comparisons between various papers.
