Parsing the Urban Poverty Puzzle A Multi-generational Panel Study in Rio de Janeiro’s Favelas, 1968–2008

This paper describes the methodology of a longitudinal multi-generational study in the favelas (shantytowns) of Rio de Janeiro from 1968 to 2008. Major political transformations took place in Brazil during this interval: from dictatorship to ‘opening’ to democracy; major economic transformations from ‘miracle’ boom to hyperinflation and crisis, and to relative stability; and major policy changes from the removal of favelas to their upgrading and integration. However, despite the cumulative effects of these contextual changes, poverty programmes and community efforts, the favela population has continued to grow faster than the rest of the city and the number and size of the favelas has consistently increased over these decades.urbanization, Brazil, poverty, community, slums

Detection of Exceptional X-Ray Spectral Variability in the TeV BL Lac 1ES 2344+514

We present the results of six BeppoSAX observations of 1ES 2344+514, five of which were taken within a week. 1ES 2344+514, one of the few known TeV BL Lac objects, was detected by the BeppoSAX Narrow Field Instruments between 0.1 to \~50 keV. During the first five closely spaced observations 1ES 2344+514 showed large amplitude luminosity variability, associated with spectacular spectral changes, particularly when compared to the last observation when the source was found to be several times fainter, with a much steeper X-ray spectrum. The energy dependent shape of the lightcurve and the spectral changes imply a large shift (factor of 30 or more in frequency) of the peak of the synchrotron emission. At maximum flux the peak was located at or above 10 keV, making 1ES 2344+514 the second blazar (after MKN501) with the synchrotron peak in the hard X-ray band. The shift, and the corresponding increase in luminosity, might be due to the onset of a second synchrotron component extending from the soft to the hard X-ray band where most of the power is emitted. Rapid variability on a timescale of approximately 5000 seconds has also been detected when the source was brightest.Comment: 7 pages, LaTeX, 6 PostScript figures. Accepted by MNRA

IFN-gamma-mediated suppression of coronavirus replication in glial-committed progenitor cells.

The neurotropic JHM strain of mouse hepatitis virus (JHMV) replicates primarily within glial cells following intracranial inoculation of susceptible mice, with relative sparing of neurons. This study demonstrates that glial cells derived from neural progenitor cells are susceptible to JHMV infection and that treatment of infected cells with IFN-gamma inhibits viral replication in a dose-dependent manner. Although type I IFN production is muted in JHMV-infected glial cultures, IFN-beta is produced following IFN-gamma-treatment of JHMV-infected cells. Also, direct treatment of infected glial cultures with recombinant mouse IFN-alpha or IFN-beta inhibits viral replication. IFN-gamma-mediated control of JHMV replication is dampened in glial cultures derived from the neural progenitor cells of type I receptor knock-out mice. These data indicate that JHMV is capable of infecting glial cells generated from neural progenitor cells and that IFN-gamma-mediated control of viral replication is dependent, in part, on type I IFN secretion

Globalization and the urban poor

The focus of this paper is the effect of contemporary globalization on poverty and inequality in cities of the ‘global south’. Specifically it addresses the impact of globalization on marginalized communities—slums, squatter settlements and shantytowns—collectively called ‘informal settlements’. This is a timely issue given that over the next 25 years virtually all of the population growth worldwide will be in the cities of developing countries largely concentrated in such settlements. The paper takes a critical look at current assumptions about globalization, urban poverty, and inequality, distinguishing between different constructs and aspects of globalization and separating causality from co-terminality. It questions how the informal sector would fare in the face of advanced capitalism and technological transformations, absent the global component. Using Brazil as an example the paper draws comparisons between the lives of the poor during the isolationist period of ‘import substitution’ and the military dictatorship and their current lives in the context of pervasive globalization of ideas, icons, and identities. The findings are based on a longitudinal panel study conducted in the favelas of Rio de Janeiro between 1968 and 2005, examining the changes over time, space and generations. The presumed effects of globalization on the lives of the urban poor, on the levels of inequality between them and the rest of the city and on public policy are thrown into question. The answers are sought in the people’s perceptions of the impact of globalization on their lives, in the historic transformations of the country and city, and in the life history, survey data and open-ended interviews collected over this 35- year period

Common Naturopathic Therapies for Chronic Conditions

Complementary and Alternative Medicine has started to achieve greater public prominence – many patients report satisfaction and believe these therapies are cost effective. Allopathic physicians are largely unfamiliar with the supplements prescribed by naturopathic doctors, and have trouble integrating these therapies into traditional treatment plans. Patients are not trained to evaluate the safety or efficacy of their medication regimens, and rely on their primary care physicians to provide that service -– even if the majority of their medications are supplements recommended by an alternative provider.https://scholarworks.uvm.edu/fmclerk/1021/thumbnail.jp
