Air Force supply officers possess a unique body of knowledge. This unique body of supply officer knowledge is an Air Force intellectual asset. The value of these intellectual assets depends on the value created by the application of the organization's knowledge and the value his knowledge creates. This thesis establishes a process for measuring the value created by unique supply officer knowledge. The first step in the methodology is to identify mandatory supply knowledge. This was accomplished through review of Air Force guidance and se of a knowledge audit questionnaire. The knowledge audit provides a means for assessing what knowledge is needed or contained within an organization. The knowledge audit conducted as part of this research effort resulted in the development of 11 mandatory supply knowledge categories consisting of 49 sub-categories. The second phase of the methodology requires the identification of unique supply officer knowledge. The identification of unique supply officer knowledge is necessary so that the contributions, or value, of the knowledge to the accomplishment of the Air Force mission can be determined. This research concludes with the development and testing of a survey instrument for use in identifying unique supply officer knowledge.

AbstractThis paper examines the relationship of the Rio de Janeiro Tramway, Light and Power Company and the municipal council in the provision of streetcar services in Rio de Janeiro, 1903–1920. Using archival materials collected in Brazil and Canada, it demonstrates that the utilities company lost the contest for control of Rio de Janeiro's mass transit system to the municipal authorities. Although it had the advantages of capital, technology and skill, this Canadian enterprise did not dictate its demands to an acquiescent municipal council. Rather, the municipal council and prefecture managed to extract an expensive streetcar system from the company to service its growing city.

For the first time in history, more than half the people of the world live in cities. Comprehending the impact of this widespread urbanization requires an awareness of the complex relationships between cities and natural ecosystems. This innovative book moves beyond the anti-urban lamentations that often dominate today's academic discourse to examine the evolution of cities and to illuminate the roles that humans play in shaping their environments, both natural and constructed. Christopher G. Boone and Ali Modarres argue that understanding the multiple forces of urbanization requires a holisti

Case studies explore the Million Trees initiative in Los Angeles; the relationship of cap-and-trade policy, public health, greenhouse gas emissions and environmental justice in Southern California; Urbanization, vulnerability and environmental justice in the Brazilian cities of Rio de Janeiro, Curitiba and São Paulo, and in Antofagasta, Greater Concepción and Valparaiso in Chile; Sociospatial patterns of vulnerability in the American southwest; and Urban flood control and land use planning in Greater Taipei, Taiwan ROC.

An introduction to urban environmental issues around the globe.

The city of Commerce, a largely industrial and Latino city east of Los Angeles, contains a disproportionately high concentration of manufacturers that emit toxic chemicals. The coincidence of a minority population and toxic sites is a classic example of environmental inequity. The authors seek to understand why industry located in this community. A historical investigation of the development of a hazardous community suggests that demographics alone are not responsible for the concentration of manufacturing in Commerce. The zoning decisions of the Los Angeles County Regional Planning Commission in the 1920s and 1930s set the pattern of industrialization in Commerce.

Objectives. Our objective is to examine spatial relationships between modeled criteria air pollutants (i.e., nitrous oxides, carbon monoxide, and ozone) and sociodemographics in metropolitan Phoenix, Arizona. Modeled air pollution offers environmental justice researchers a new and robust data source for representing chronic environmental hazards.Methods. We used multiple regression equations to predict criteria pollution levels using sociodemographic variables at the Census block group level.Results. We find that Census block groups with lower neighborhood socioeconomic status, higher proportions of Latino immigrants, and higher proportions of renters are exposed to higher levels of criteria air pollutants. Proportion African American, however, is not a significant predictor of criteria air pollution in the Phoenix metro area.Conclusions. These findings demonstrate clear social‐class and ethnic‐based environmental injustices in the distribution of air pollution. We attribute these patterns to the role of white privilege in the historical and contemporary development of industrial and transportation corridors in Phoenix in relation to racially segregated neighborhoods. Although all people are implicated in the production of criteria pollutants, lower‐income and ethnic‐minority residents are disproportionately exposed in metropolitan Phoenix.
