Reconsidering Traditional Urbanism

The 1999 Weiss Symposium series assembled a dozen leading figures from the fields of planning, architecture, history, sociology, psychology, and journalism to discuss and debate traditional urbanism in five events held in the spring of 1999 at the University of North Carolina at Chapel Hill. This special section presents the ideas of three participants: Robert Russell, James Howard Kunstler, and Carroll William Westfall

Planner's Digest: Traditional Urbanism Reconsidered: The 1999 Weiss Urban Livability Symposium

It would be impossible to discuss urban livability without confronting the concept of urbanism - its many, varied forms, historical basis, aesthetic qualities, functional performance, and urban lifestyles. The 1999 Weiss Symposium at the University of North Carolina at Chapel Hill campus presents a unique end-of-the-century opportunity to reflect on traditional urbanism, and to ponder the future of urbanism in a world where the importance of local communities and a sense of place are increasingly challenged by technological advances, globalism, and the commodification of urban places. Presenters and participants will consider and debate the contemporary relevance of traditional urban forms as more sustainable, livable alternatives in an age of sprawl

Piecewise Linear Models for the Quasiperiodic Transition to Chaos

We formulate and study analytically and computationally two families of piecewise linear degree one circle maps. These families offer the rare advantage of being non-trivial but essentially solvable models for the phenomenon of mode-locking and the quasi-periodic transition to chaos. For instance, for these families, we obtain complete solutions to several questions still largely unanswered for families of smooth circle maps. Our main results describe (1) the sets of maps in these families having some prescribed rotation interval; (2) the boundaries between zero and positive topological entropy and between zero length and non-zero length rotation interval; and (3) the structure and bifurcations of the attractors in one of these families. We discuss the interpretation of these maps as low-order spline approximations to the classic ``sine-circle'' map and examine more generally the implications of our results for the case of smooth circle maps. We also mention a possible connection to recent experiments on models of a driven Josephson junction.Comment: 75 pages, plain TeX, 47 figures (available on request

New Urbanism and the City: Potential Applications and Implications for Distressed Inner-‐City Neighborhoods.” Housing Policy Debate

Abstract New Urbanism has been described as the most influential movement in architecture and planning in the United States since the Modernist movement. In recent years, New Urbanist design principles have been adopted for many housing and neighborhood planning efforts. This article considers the applications and implications of New Urbanism for distressed inner-city neighborhoods. Claims and criticisms of New Urbanism are examined and the long-standing debates over the extent to which physical planning and design can affect human behavior are revisited. The article concludes that New Urbanism is not a panacea, but that its design principles are consistent with broader policies aimed at revitalizing and improving living conditions and opportunities for inner-city residents. New Urbanism needs to be viewed as one strategy to be integrated within the larger array of economic, social, and community development programs attempting to revitalize and improve the quality of life in inner-city neighborhoods

Immunohistochemical toolkit for tracking and quantifying xenotransplanted human stem cells.

Biomarker-based tracking of human stem cells xenotransplanted into animal models is crucial for studying their fate in the field of cell therapy or tumor xenografting.Journal ArticleSCOPUS: ar.jinfo:eu-repo/semantics/publishe
