The twistor transform of a Verlinde formula

The topology of the smooth moduli space of stable rank 2 bundles over a Riemann surface of genus 3 is related to that of the real Grassmannian Gr_4(R^8).Comment: AMSLaTeX, 14 page

Cohomology of Kaehler manifolds with c_1=0

A linear constraint is given on the Betti numbers of a compact hyper-Kaehler manifold, using an index formula for c_1c_{n-1} on an almost complex manifold. The topology of some other manifolds with reduced holonomy is also discussed briefly

The New Governance and the Tools of Public Action: An Introduction

A fundamental re-thinking is currently underway throughout the world about how to cope with public problems. Stimulated by popular frustrations with the cost and effectiveness of government programs and by a new-found faith in liberal economic theories, serious questions are being raised about the capabilities, and even the motivations, of public-sector institutions. This type of questioning has spread beyond American political discourse to other parts of the world. Underlying much of this reform surge is a set of theories that portrays government agencies as tightly structured hierarchies insulated from market forces and from effective citizen pressure and therefore free to serve the personal and institutional interests of bureaucrats instead. The heart of this revolution has been a fundamental transformation not just in the scope and scale of government action, but in its basic forms. Instead of relying exclusively on government to solve public problems, a host of other actors is being mobilized as well, sometimes are their own initiative but often in complex partnerships with the state

Intersection numbers on moduli spaces and symmetries of a Verlinde formula

We investigate the geometry and topology of a standard moduli space of stable bundles on a Riemann surface, and use a generalization of the Verlinde formula to derive results on intersection pairings.Comment: AMSLaTex, 15 pages with 1 figur

Volunteering in Cross-National Perspective: Initial Comparisons

Anheier and Salamon shed some light on volunteering in different parts of the world by exploring the conceptions and patterns of voluntary action cross-nationally. As a cultural and economic phenomenon, volunteering is part of the way societies are organized, how they allocate social responsibilities, and how much engagement and participation they expect from citizens

Absorption of High Energy Gamma Rays by Interactions with Extragalactic Starlight Photons at High Redshifts

We extend earlier calculations of the attenuation suffered by gamma rays during their propagation from extragalactic sources, obtaining new extinction curves for gamma rays down to 10 GeV in energy, from sources up to a redshift of z=3.Comment: 5 pages, 3 imbedded EPS figures; requires aipproc macros (not included).
