Orientals Need Apply: Gender-based Asylum in the U.S.
Every other year I teach a course entitled The History of Asian Women in America, which focuses on the experiences of East, South and Southeast Asian women as they journey to these shores and resettle. Using autobiographies, poetry, journal writings, interviews and academic texts, the students learn from the women what political, social, cultural, economic and ecological conditions prompted them to leave their homelands and why they chose the United States. We learn of their rich cultural backgrounds, their struggles to create a subculture based on their home and host experiences, and the cultural gaps that often appear between the first and subsequent generations. And we also learn how patriarchy affects their lives transnationally. In spite of all this information, inevitably one student always asks why are Asian cultures so oppressive to women
Neutrino Mass Matrix in Terms of Up-Quark Masses
We demonstrate that under the "symmetric zero texture" with minimal Majorana
mass matrix, neutrino masses and mixing angles are expressed in terms of
up-quark masses, . This provides interesting relations among
neutrino mixing angles and up-type quark masses. Especially we predict
even if we include the small mixing effects coming from
charged lepton side. Also absolute masses of three neutrinos are predicted
almost uniquely. This is quite in contrast to the case where bi-large mixings
come from the charged lepton sector with non-symmetric charged lepton mass
matrix.Comment: 9 pages, latex, 2 figures. Talk presented by Bando at the 2002

Neutrino Mass Matrix Predicted From Symmetric Texture
Within the framework of grand unified theories, we make full analysis of
symmetric texture to see if such texture can reproduce large neutrino mixings,
which have recently been confirmed by the observed solar and atmospheric
neutrino oscillation experiments. It is found that so-called symmetric texture
with anomalous U(1) family symmetry with Froggatt-Nielsen mechanism does not
provide a natural explanation of two large mixing angles. On the contrary we
should adopt "zero texture" which have been extensively studied by many authors
and only this scenario can reproduce two large mixing angles naturally. Under
such "zero texture" with minimal symmetric Majorana matrix, all the neutrino
masses and mixing angles, 6 quantities, are expressed in terms of up-quark
masses, with two adjustable parameters. This provides interesting
relations among neutrio mixing angles, . Thus
is predicted to lie within the range . Also absolute
masses of three neutrinos are predicted almost uniquely. This is quite in
contrast to the case where bi-large mixings come from the charged lepton sector
with non-symmetric mass matrix, which does not provide the information of
neutrino masses.Comment: 23 pages, latex, 15 figures. Preprint version contains "low

Neutrino Bi-Large Mixings and Family
After a brief review of quark-lepton relations in grand unified theories
(GUT), we show that the Pati-Salam relation with only one type of Higgs field
configuration with "four zero symmetric texture" can reproduce two large
neutrino mixings as well as observed mass differences. This is quite in
contrast to the case of SU(5) where bi-large mixings essentially come from the
charged lepton sector with non-symmetric charged lepton mass matrix.Comment: 6 pages, latex, uses ws-procs9x6.cls. Talk presented by Bando at 4th
