Proyectos y reformas urbanas en Constantina en los siglos XIX y XX

The urban development of Constantina has been historically characterised by its adaptation to the lineal and sinuous morphology of the valley of the Osa. During the nineteenth century and the first thirty years of the twentieth its present day image was defined as the result of a progressive piping of the Villa river that allowed the settlement on its banks. A new North-South urban axis was thus established from the Alameda to the piazza of Santa Ana to arrange the new public facilities (a cementery, a public market, a school and the town council). All these buildings were designed by architects of great interest for the history of Sevillian urbanism. At the same time other minor works prepared the...

The Postdiagnosis Mobility of People with AIDS

This paper is an analysis of the postdiagnosis mobility of people diagnosed with AIDS (acquired immunodeficiency syndrome) in Florida. I infer intrastate mobility by comparing the county of diagnosis on an individual's AIDS case report with that on the matched death certificate; this allows the measurement of migration within the state of Florida for 4393 people through October, 1989–46% of the total cases by that time. Out-migration rates in rural counties are very high, approximately 50%, whereas those in large metropolitan counties are less than 10%; however, these rates depend on race. The data show that migrants moved to places with concentrations of health-care facilities, and that there is a flow of migrants from rural to urban places, particularly to large metropolitan areas. The results suggest that the spatial distribution of people with AIDS changes in the period after diagnosis, becoming more concentrated in places where there are good health-care facilities. There is descriptive evidence to suggest that the orientation of flows changes with the deteriorating health status of migrants from a distinctly rural to urban axis to a more diffuse pattern, but the statistical test for this change is inconclusive.

Los Angeles and the anti-tradition of the suburban city

An anti-urban image of Los Angeles that projected the city as a sprawling suburban expanse of automobile freeways and smog without a downtown skyline was broadcast in the national press after the First World War, climaxing in 1960. The national emotional response to the lack of urban order in Los Angeles was triggered by the night view from the Hollywood Hills and realized in the imagery of Los Angeles as “Six suburbs in search of a city”. In fact, the night view of the Los Angeles Basin defined the emergent urban axis of Wilshire Boulevard, expanding west from the downtown district along the elite corridor to Beverly Hills and the Pacific shore. The result of the continued development of both Wilshire Boulevard and the downtown district was a revision of the anti-urban imagery, signaled by high-rise construction and increasing urban density after 1960. Recent critical imagery of Los Angeles appears to be based on deep-rooted notions of traditional urban density and Old World pre-industrial city structure. The result is a continuing evaluation of Los Angeles in the national press as a terrae incognitae when compared with New York City as the traditional city prototype of the oikoumene.

Inmigrantes emprendedores durante la crisis económica. Estudio de casos en la ciudad de Madrid

Los inmigrantes emprendedores han tenido que adaptar sus negocios o, incluso, abandonarlos, debido al impacto de la crisis económica que ha afectado de forma muy especial al consumo y, por tanto, a la actividad comercial en general. Para apreciar los cambios habidos en esta etapa se han seleccionado seis ejes urbanos de la ciudad de Madrid, con presencia significativa de negocios de titularidad extranjera, y que los autores habían estudiado en el año 2009. Y se han vuelto a visitar y analizar en 2015. Actualmente, el llamado empresariado étnico, para mantener sus negocios, tiende a captar una clientela más amplia, abandonando una excesiva especialización y mejorando la presencia de los establecimientos comerciales y de los productos y servicios que ofrece.

Equilibrium traffic on an urban axis and distribution of users between public and private transportation

THE PAPER CONTAINS A THEORETICAL STUDY OF THE DISTRIBUTION BETWEEN PRIVATE AND PUBLIC TRANSPORTATION OF PERSONS USING A ONE-WAY AXIS. A COMPARISON OF BEHAVIOR OF PERSONS WISHING TO USE THE ROUTE UNDER ALLOWABLE CONDITIONS OF FLOW LEADS TO A TRAFFIC EQUILIBRIUM, VARIABLE WITH TIME. THE AUTHOR OBTAINS THE CONDITIONS NECESSARY FOR THE EXISTENCE OF AN EQUILIBRIUM, AND SHOWS HOW THE EQUILIBRIUM VALUES CAN BE OBTAINED. IN PARTICULAR HE STUDIES TWO TYPES OF PARKING, EITHER AT THE CITY CENTER OR AT THE LIMIT BETWEEN THE CITY CENTER AND THE SUBURB. THE MODEL WHICH IS DEVELOPED FURNISHED SEVERAL ELEMENTS FOR ECONOMIC COMPARISON OF VARIANTS IN THE URBAN TRANSPORTATION INFRASTRUCTURE. /AUTHOR/
