Chinatown Black Tigers: Black Masculinity and Chinese Heroism in Frank Chin\u27s Gunga Din Highway
Images of ominous villains and asexual heroes in literature and mainstream American culture tend to relegate Asian American men to limited expressions of masculinity. These emasculating images deny Asian American men elements of traditional masculinity, including agency and strength. Many recognize the efforts of Frank Chin, a Chinese American novelist, to confront, expose, and revise such images by relying on a tradition of Chinese heroism. In Gunga Din Highway (1994), however, Chin creates an Asian American masculinity based on elements of both the Chinese heroic tradition and a distinct brand of African American masculinity manifested in the work of Ishmael Reed, an African American novelist and essayist known for his outspoken style.^1 Rather than transforming traditional masculinity to include Asian American manhood, Chin\u27s images of men represent an appropriation of elements from two ethnic sources that Chin uses to underscore those of Asian Americans. While deconstructing the reductive images advocated by the dominant culture, Chin critiques the very black masculinity he adopts. Ultimately he fails to envision modes of masculinity not based on dominance, yet Chin\u27s approach also can be read as the ultimate expression of Asian American individualism
Buckling and vibration of periodic lattice structures
Lattice booms and platforms composed of flexible members or large diameter rings which may be stiffened by cables in order to support membrane-like antennas or reflector surfaces are the main components of some large space structures. The nature of these structures, repetitive geometry with few different members, makes possible relatively simple solutions for buckling and vibration of a certain class of these structures. Each member is represented by a stiffness matrix derived from the exact solution of the beam column equation. This transcendental matrix gives the current member stiffness at any end load or frequency. Using conventional finite element techniques, equilibrium equations can be written involving displacements and rotations of a typical node and its neighbors. The assumptions of a simple trigonometric mode shape is found to satisfy these equations exactly; thus the entire problem is governed by just one 6 x 6 matrix equation involving the amplitude of the displacement and rotation mode shapes. The boundary conditions implied by this solution are simple supported ends for the column type configurations

Product line design
We characterize the product line choice and pricing of a monopolist from the upper envelope of net marginal revenue curves to the individual product demand functions. The equilibrium product line constitutes those varieties yielding the highest upper envelope. In a generalized vertical differentiation framework, the equilibrium line is exactly the same as the first-best socially optimal line. These upper envelope and first-best optimal line findings extend to symmetric Cournot oligopoly

Properties which normal operators share with normal derivations and related operators
Let and be (bounded) scalar operators on a Banach space \scr X and let be the map on \scr B(\scr X), the bounded linear operators on \scr X, defined by for in \scr B(\scr X). This paper was motivated by the question: to what extent does behave like a normal operator on Hilbert space? It will be shown that does share many of the special properties enjoyed by normal operators. For example, it is shown that the range of meets its null space at a positive angle and that is Hermitian if and are Hermitian. However, if \scr X is a Hilbert space then is a spectral operator if and only if the spectrum of and the spectrum of are both finite
The distribution of species range size: a stochastic process
The major role played by environmental factors in determining the geographical range sizes of species raises the possibility of describing their long-term dynamics in relatively simple terms, a goal which has hitherto proved elusive. Here we develop a stochastic differential equation to describe the dynamics of the range size of an individual species based on the relationship between abundance and range size, derive a limiting stationary probability model to quantify the stochastic nature of the range size for that species at steady state, and then generalize this model to the species-range size distribution for an assemblage. The model fits well to several empirical datasets of the geographical range sizes of species in taxonomic assemblages, and provides the simplest explanation of species-range size distributions to date
