Beyond Ethnicity: Toward a Critique of the Hegemonic Discipline E. San Juan, Jr.

With the current vogue of multiculturalism and cultural diversity requirements as panacea for systemic problems, scholars and teachers of Ethnic Studies need to reassess the principles and goals of their discipline. Los Angeles 1992, among other developments, has exposed the serious inadequacies of old paradigms. A review of the racialized history of Asians in U.S. society, a narrative of oppression and opposition now mystified by the model minority myth, allows us to grasp the flaws of the liberal pluralist focus on culture divorced from the political and economic contexts of unequal power relations. Ultimately, for whom is Ethnic Studies designed? By historicizing identity politics and validating the genealogy of resistance, we in the field of Ethnic Studies can refuse to be mere apologists for the status quo and revitalize the critical and emancipatory thrust of Ethnic Studies, a thrust inseparable from the struggle of people of color against white supremacy

Weak Hyperbolicity on Periodic Orbits for Polynomials

We prove that if the multipliers of the repelling periodic orbits of a complex polynomial grow at least like $n^{5 + \epsilon}$, for some $\epsilon > 0$, then the Julia set of the polynomial is locally connected when it is connected. As a consequence for a polynomial the presence of a Cremer cycle implies the presence of a sequence of repelling periodic orbits with "small" multipliers. Somehow surprinsingly the proof is based in measure theorical considerations.Comment: 6 pages, Late

From Chinatown to Gunga Din Highway: Notes on Frank Chin\u27s Writing Strategy

Exploring Frank Chin\u27s work, particularly in his latest novel Gunga Din Highway, the essay endeavors to re-situate ethnic writing in the historical specificity of its inscription in the United States as a racial polity. This cognitive remapping of the literary field as reconfigured by multiculturalist liberalism may be accomplished by examining Chin\u27s cultural politics. Chin\u27s mode of strategic writing interrogates the modelminority myth and the premises of cultural nationalism. While it rejects the pluralist resolution of the traditional conflicts in the Chinese diaspora, Chin\u27s satiric impulse proposes a defamiliarization of Asian American common sense adequate to provoke a revaluation of the presumed conjunction of ethnicities, cultures, and nationalities in the current counter-terrorist milieu

Spin-orbit signatures in the dynamics of singlet-triplet qubits in double quantum dots

We characterize numerically and analytically the signatures of the spin-orbit interaction in a two-electron GaAs double quantum dot in the presence of an external magnetic field. In particular, we obtain the return probability of the singlet state by simulating Landau-Zener voltage detuning sweeps which traverse the singlet-triplet ($S-T_+$) resonance. Our results indicate that non-spin-conserving interdot tunneling processes arising from the spin-orbit interaction have well defined signatures. These allow direct access to the spin-orbit interaction scales and are characterized by a frequency shift and Fourier amplitude modulation of the Rabi flopping dynamics of the singlet-triplet qubits $S-T_0$ and $S-T_+$. By applying the Bloch-Feshbach projection formalism, we demonstrate analytically that the aforementioned effects originate from the interplay between spin-orbit interaction and processes driven by the hyperfine interaction between the electron spins and those of the GaAs nuclei

Mining for Culture: Reaching Out of Range

The goal of this paper is to present a tool that will sustain the development of culturally relevant computing artifacts by providing an effective means of detecting culture identities and cultures of participation. Culturally relevant designs rely heavily on how culture impacts design and though the guidelines for producing culturally relevant objects provide a mechanism for incorporating culture in the design, there still requires an effective method for garnering and identifying said cultures that reflects a holistic view of the target audience. This tool presents culturally relevant designs as a process of communicating with key audiences and thus bridging people and technology in a way that once seemed out of range

Edge Effects in Finite Elongated Graphene Nanoribbons

We analyze the relevance of finite-size effects to the electronic structure of long graphene nanoribbons using a divide and conquer density functional approach. We find that for hydrogen terminated graphene nanoribbons most of the physical features appearing in the density of states of an infinite graphene nanoribbon are recovered at a length of 40 nm. Nevertheless, even for the longest systems considered (72 nm long) pronounced edge effects appear in the vicinity of the Fermi energy. The weight of these edge states scales inversely with the length of the ribbon and they are expected to become negligible only at ribbons lengths of the order of micrometers. Our results indicate that careful consideration of finite-size and edge effects should be applied when designing new nanoelectronic devices based on graphene nanoribbons. These conclusions are expected to hold for other one-dimensional systems such as carbon nanotubes, conducting polymers, and DNA molecules.Comment: 4 pages, 4 figure

A comparison of the accuracy of saddlepoint conditional cumulative distribution function approximations

Consider a model parameterized by a scalar parameter of interest and a nuisance parameter vector. Inference about the parameter of interest may be based on the signed root of the likelihood ratio statistic R. The standard normal approximation to the conditional distribution of R typically has error of order O(n^{-1/2}), where n is the sample size. There are several modifications for R, which reduce the order of error in the approximations. In this paper, we mainly investigate Barndorff-Nielsen's modified directed likelihood ratio statistic, Severini's empirical adjustment, and DiCiccio and Martin's two modifications, involving the Bayesian approach and the conditional likelihood ratio statistic. For each modification, two formats were employed to approximate the conditional cumulative distribution function; these are Barndorff-Nielson formats and the Lugannani and Rice formats. All approximations were applied to inference on the ratio of means for two independent exponential random variables. We constructed one and two-sided hypotheses tests and used the actual sizes of the tests as the measurements of accuracy to compare those approximations.Comment: Published at http://dx.doi.org/10.1214/074921707000000193 in the IMS Lecture Notes Monograph Series (http://www.imstat.org/publications/lecnotes.htm) by the Institute of Mathematical Statistics (http://www.imstat.org

The Energy-Momentum Method

This paper develops the energy momentum methodJor studying stability and bifurcation of Lagrangian and Hamiltonian systems with symmetry. The method was specifically designed to deal with the stability of rotating structures. The relation with the energy-Casimir method is given and the energy-momentum method is shown to be more general. Stability of rigid body motion is given 10 illustrate the method. Some discussion of its applicability to general rotating systems and block diagonalization is also given
