How does race operate among Asian Americans in the labor market? : Occupational segregation and different rewards by occupation among native-born Chinese American and Japanese American male workers
The effect of race in the U.S. labor market has long been controversial. One posits that racial effects have been diminished since the civil rights movement of the 1960s (Alba & Nee, 2003; Sakamoto, Wu, & Tzeng, 2000; Wilson, 1980). Even if some disparities in labor-market outcomes among race groups are found, advocates of this declining significance of race thesis do not attribute these disparities to racial discrimination. They, instead, understand the racial gaps as a result of class composition of racial minority groups, classes represented by larger proportions of the working-class population (Wilson, 1980, 1997) as well as unskilled-immigrant workers (Borjas, 1994)
New Physics Searches with Photons in CDF
A brief review of searches for physics beyond the Standard Model with photons
using the CDF detector at the Tevatron is given here. These include searches
for supersymmetry, extra dimensions, excited electrons and W/Z
production, as well as anomalous photon production. Recent results from CDF Run
II experiment is presented, but some results from Run I are also reviewed.Comment: To appear in the Proceedings of SUSY 2003, held at the University of
Arizona, Tucson, AZ, 5-10 June 200
Searches for Physics Beyond the Standard Model at CMS
Recent results on searches for physics beyond the Standard Model at Large
Hadron Collider are presented, based on early LHC data in proton-proton
collisions at TeV collected by the CMS experiment. Prospects of
early SUSY searches at CMS are also outlined.Comment: 6 pages, Proceedings of Hadron Collider Physics Symposium, HCP 2010,

On the Profiles and Polarization of Raman Scattered Emission Lines in Symbiotic Stars:II. Numerical Simulations
A Monte Carlo method is used to calculate the profiles and the polarization
of the Raman scattered O VI lines(lambda lambda 6827,7088) in symbiotic stars.
A point-like isotropic UV radiation source is assumed and a simple spherical
wind model is adopted for the kinematics of the scattering material from the
cool giant. We first investigate the case where the incident line photons are
described by a Gaussian profile having a width of 10^4 K. We subsequently
investigate the effects of the extended ionized region and non-spherical wind
models including a disk-type wind and a bipolar wind. The cases where the
emissin source is described by non-Gaussian profiles are briefly studied.
Finally, as an additional component for the kinematics of symbiotic stars the
orbital motion of the hot component around the cool giant is included and the
effect on the spectropolarimetry is investigated. In this case the polarization
direction changes around the red part of the Raman-scattered emission lines,
when the observer's line of sight is perpendicular to the orbital plane, and no
such effect is seen when the line of sight lies in the orbital plane.
Furthermore, complex peak structures are seen in the degree of polarization and
polarized flux, which have often been observed in several symbiotic systems
including RR Tel. Brief observational consequences and preditions are discussed
in relation to the present and future spectropolarimetry for symbiotic stars.
It is concluded that spectropolarimetry may provide a powerful diagnostic of
the physical conditions of symbiotic stars.Comment: 22 pages, Tex, 15 postscript figuer
Gap Symmetry and Thermal Conductivity in Nodal Superconductors
Here we consider the universal heat conduction and the angular dependent
thermal conductivity in the vortex state for a few nodal superconductors. We
present the thermal conductivity as a function of impurity concentration and
the angular dependent thermal conductivity in a few nodal superconductors. This
provides further insight in the gap symmetry of superconductivity in
SrRuO and UPdAl.Comment: 2 pages, proceedings of SCES '0
