Critique [of The Ethnic Matrix: Implications for Human Service Practitioners by Jesse M. Vazquez]

Vazquez\u27s psychosocial model for understanding ethnicity and the ethnic process in American society and how this model could be used by practitioners and researchers to further expand their own work is noble. Vazquez fulfilled his purpose. However, the underlying assumption is somewhat misleading, i.e., practitioners and researchers, generally, are not employing the ethnic matrix model. Vazquez states that the absence of ethnic content and concern with ethnic issues in professional training programs was seriously questioned

Studies of Inclusive Jet Production in ep Interactions at HERA

Inclusive jet production in neutral and charged current deep inelastic scattering, in photoproduction and the transition region has been studied with the ZEUS and H1 detectors at HERA. The measurements have been compared to next-to-leading-order QCD calculations which are used to make determinations of the strong coupling constant.Comment: 3 pages, 5 figures, Conference Proceedings EPS200

Self-organization in populations of competing agents

A population of heterogenous agents compeeting through a minority rule is investigated. Agents which frequently loose are selected for evolution by changing their strategies. The stationary composition of the population resulting for this self-organization process is computed analytically. Results are compared with numerical simulations of two different minority games and other analytical treatments available in the literature.Comment: RevTex, 4 pages, 1 ps fi
