The Orbital Ephemeris and X-Ray Light Curve of Cyg X-3
The orbital dynamics of Cyg X-3 are a key to understanding this enigmatic
X-ray binary. Recent observations by the RXTE ASM and the OSSE instrument on
GRO enable us to extend the baseline of arrival time measurements and test
earlier models of orbital period evolution. We derive new quadratic and cubic
ephemerides from the soft X-ray data (including ASM). We find a significant
shift between the predicted soft X-ray phase and the light curve phase measured
by OSSE from ~44 to 130 keV. Some of the apparent phase shift may be caused by
a difference in light curve shape.Comment: 5 pages, 2 figures, LaTeX (aipproc); to be published in the

Sato-Tate equidistribution for families of Hecke-Maass forms on SL(n,R)/SO(n)
We establish the Sato-Tate equidistribution of Hecke eigenvalues on average
for families of Hecke--Maass cusp forms on SL(n,R)/SO(n). For each of the
principal, symmetric square and exterior square L-functions we verify that the
families are essentially cuspidal and deduce the level distribution with
restricted support of the low-lying zeros. We also deduce average estimates
toward Ramanujan
Public employment and the double role of bureaucrats
Bureaucrats in the government sector have a double role since they are both suppliers and demanders of public employment; they are publicly employed (supply labor) and they have an important say in deciding the size of the municipal employment (demand labor). In this paper we present and estimate a theoretical model that focuses on this double role of bureaucrats. The predictions from the theoretical model are supported by our empirical results: The estimates based on data from Swedish municipalities 1990–2002, show that wages have smaller effects on the demand for bureaucrats than on the demand for other types of public employees. Actually wages have no significant effect on the number of bureaucrats the municipality employs.Public employment; bureaucrats
