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, $m_t,m_c,m_u$. This provides interesting relations among neutrino mixing angles and up-type quark masses. Especially we predict $|U_{e3}| \leq 0.11$ 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.

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, $m_t,m_c,m_u$ with two adjustable parameters. This provides interesting relations among neutrio mixing angles, $\tan^2 2\theta_{12} \simeq \frac{144m_c}{m_t} \tan^2 2\theta_{23} \cos^2 \theta_{23}, \quad \sin^2 \theta_{13} \simeq \frac{4m_c}{m_t}\sin^2 \theta_{23} \cos^2 \theta_{12}$. Thus $|U_{e3}|$ is predicted to lie within the range $0.01-0.06$. 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.

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.
