Seria razoável, como base para discussão do nosso tema, fazer um breve resumo das qualidades que, em outras reuniões de treinamento, tive ocasião de mencionar como atributos da liderança. Enumerei-as como representativas do conhecimento em três áreas diferentes — definição de objetivos, organização e natureza humana — e chamei-as imaginação, responsabilidade, habilidade para escolher auxiliares adequados, para delegar competência; decisão, critério, integridade, ausência de egoísmo, lealdade, paciência, coragem e fé — em si mesmo, nos outros, no futuro e em Deus.

This paper explores the effect of the Earned Income Tax Credit (EITC) on poor neighborhoods of Los Angeles during the late 1990s. To date, few analyses have empirically examined the impact of people-based policies on the economies of poor neighborhoods. The paper first documents the magnitude of this individual wage subsidy in Los Angeles as an unrecognized investment in poor neighborhoods on par with place-based policies such as Enterprise Zones. The paper then uses IRS and Economic Census data by ZIP Code to test whether increased EITC income has an effect on the neighborhood retail job base. Findings suggest an independent correlation between EITC investments and retail job gain. The conclusion uses these results to suggest better policy coordination and recommend four productive areas for future research.

An algorithm is designed to extract features from video of an air refueling tanker for use in determining the precise relative position of a receiver aircraft. The algorithm is based on receiving a known estimate of the tanker aircraft's position and attitude. The algorithm then uses a known feature model of the tanker to predict the location of those features on a video frame. A corner detector is used to extract features from the video. The measured corners are then associated with known features and tracked from frame to frame. For each frame, the associated features are used to calculate three dimensional pointing vectors to the features of the tanker. These vectors are passed to a navigation algorithm which uses extended Kalman filters, as well as data-linked INS data to solve for the relative position of the tanker. The algorithms were tested using data from a flight test accomplished by the USAF Test Pilot School using a C-12C as a simulated tanker and a Learjet LJ-24 as the simulated receiver. The system was able to provide at least a dozen useful measurements per frame, with and without projection error.

This article attempts to place the concept of indigeneity in the context of contemporary conflicts and claims to resources in the face of increasing global integration. Rather than treating indigenous politics as primarily a product of historical and (European) colonial conflict of culture and race/ethnicity, I use the example of recent land conflicts in the Mekong Delta of Vietnam as a starting point toward understanding contemporary debates on indigeneity. Based on fieldwork in 1994, the article describes one community's conflict over resource-use that demonstrates how land law, local rules of access, and the evolution of competing claims to land can create politicized socio-spatial localities overnight. Such communities, though sharing a similar culture, language, and history with the dominant nation, maintain local meanings and rules of access that define a distinct socio-spatial community. This example from Vietnam suggests that contemporary globalization and market integration is creating new indigenous communities that need to be better understood.
