Discretized gravity on the hyperbolic disk

We consider a description of lattice gravity in six dimensions, where the two extra dimensions have been compactified on a warped hyperbolic disk of constant curvature. We analyze a fine-grained latticization of the hyperbolic disk in the context of an effective theory for massive gravitons. We find that in six-dimensional warped hyperbolic space, lattice gravity appears near the boundary of the disk more weakly coupled than in discretized five-dimensional flat or warped space. Specifically, near the IR branes, the local strong coupling scale can become as large as the local Planck scale.Comment: 4 pages, 2 figures, to appear in Proceedings of SUSY06, the 14th Conference on Supersymmetry and the Unification of Fundamental Interactions, UC Irvine, California, 12-17 June 200

Employment Stability Under Different Managerial Compensation Systems

Compensation design may influence the extent to which managerial decision-makers take a long-term perspective in managing important resources like employees. I hypothesize that organizations relying more heavily on long-term compensation incentives exhibit greater stability in employment, perhaps because of a greater concern among management with long-term effectiveness. I also hypothesize that employment stability is more feasible when employees are covered by variable pay plans, which permit labor cost reductions without cuts in employment. Using multiple years of employment, financial performance, and managerial compensation data on 156 organizations, support is found for both hypotheses

A review of the biology and management of horseshoe crabs, with emphasis on Florida populations

In Florida, some horseshoe crabs are fished for eel bait, but they are fished principally by the marine-life industry, which collects the animals live for resale as aquarium, research, or educational specimens. The regulations for the horseshoe crab fisheries are developed by each state in compliance with the Atlantic States Marine Fisheries Commission (ASMFC) Horseshoe Crab Management Plan. This report was written to provide information on the biology, stock status, and management of horseshoe crabs and the implications relevant to the request for an increased bag limit by harvesters in the marine-life industry

Gender Differences in Current and Starting Salaries: The Role of Performance, College Major, and Job Title

Starting and current salaries of 3,564 men and 1,053 women hired between 1976 and 1986 by a large, private firm were examined. Using a comprehensive model including year of hire, potential experience, education degree, college major, firm tenure, performance, and job title, men were found to have 5.8% higher current salaries. Among college graduates, men ~alized a 2.9% current salary advantage. Further analyses suggested that the bulk of the current salary disadvantage of women could be attributed to a one-time salary shortfall incurred at the time of hire. Although among college graduates, for example, differences in college major explained much of the starting salary advantage for men, an unexplained 4.8% advantage in starting salaries remained. Although women were more likely to leave the firm, correction for this potential source of sample selection bias did not change the pattern of results. Finally, we suggest that the fact that women experience a greater salary disadvantage at entry may stem from the smaller amount of job-relevant information available for applicants relative to current employees.
