This paper examines how the density of corporate and bank headquarters in a community, and the degree of social interconnection among local elites, influence changes in the density of different types of non-profit organizations. We contrast a cohesion approach, which emphasizes the positive influences of corporations and well-connected civic elites, with a critical approach that takes a skeptic...

This paper studies the possibility of implementing Pareto optimal outcomes in the combinatorial auction setting where bidders may have budget constraints. I show that when the setting involves a single good, or multiple goods but with single-minded bidders, there is a unique mechanism, called truncation VCG, that is individually rational, incentive compatible and Pareto optimal. Truncation VCG ...

One of the biggest challenges facing human service organizations is the proliferation of information from inside and outside the agency that needs to be managed if it is to be of use. The concepts of tacit and explicit knowledge can inform an approach to this challenge. Tacit knowledge is stored in the minds of practitioners (often called practice wisdom) and the explicit knowledge is often fou...

In certain complex optimization tasks, it becomes necessary to use multiple measures to characterize the performance of di erent algorithms. This paper presents a method that combines ordinal e ect sizes with Pareto dominance to analyze such cases. Since the method is ordinal, it can also generalize across di erent optimization tasks even when the performance measurements are di erently scaled....

Some modern writers on mental deficiency regard the feeble-minded as a class that has some one mental defect in common, varying in degree only. This simple conception is perhaps due to the tendency of late years to emphasise the quantitative aspect of mental deficiency and to neglect qualitative distinctions. But teachers, psychologists, and medical officers, who deal with the practical problem...
