Inequalities in mortality of men by oral and pharyngeal cancer in Barcelona, Spain and Sao Paulo, Brazil, 1995-2003

Background: Large inequalities of mortality by most cancers in general, by mouth and pharynx cancer in particular, have been associated to behaviour and geopolitical factors. The assessment of socioeconomic covariates of cancer mortality may be relevant to a full comprehension of distal determinants of the disease, and to appraise opportune interventions. The objective of this study was to compare socioeconomic inequalities in male mortality by oral and pharyngeal cancer in two major cities of Europe and South America. Methods: The official system of information on mortality provided data on deaths in each city; general censuses informed population data. Age-adjusted death rates by oral and pharyngeal cancer for men were independently assessed for neighbourhoods of Barcelona, Spain, and Sao Paulo, Brazil, from 1995 to 2003. Uniform methodological criteria instructed the comparative assessment of magnitude, trends and spatial distribution of mortality. General linear models assessed ecologic correlations between death rates and socioeconomic indices (unemployment, schooling levels and the human development index) at the inner-city area level. Results obtained for each city were subsequently compared. Results: Mortality of men by oral and pharyngeal cancer ranked higher in Barcelona (9.45 yearly deaths per 100,000 male inhabitants) than in Spain and Europe as a whole; rates were on decrease. Sao Paulo presented a poorer profile, with higher magnitude (11.86) and stationary trend. The appraisal of ecologic correlations indicated an unequal and inequitably distributed burden of disease in both cities, with poorer areas tending to present higher mortality. Barcelona had a larger gradient of mortality than Sao Paulo, indicating a higher inequality of cancer deaths across its neighbourhoods. Conclusion: The quantitative monitoring of inequalities in health may contribute to the formulation of redistributive policies aimed at the concurrent promotion of wellbeing and social justice. The assessment of groups experiencing a higher burden of disease can instruct health services to provide additional resources for expanding preventive actions and facilities aimed at early diagnosis, standardized treatments and rehabilitation.

A Different Perspective for Investigation of PCC Pavement Deterioration, HR-2074, 1995

Portland Cement Concrete (PCC) pavement has served the State of Iowa well for many years. The oldest Iowa pavement was placed in LeMars in 1904. Beginning in 1931, many miles of PCC pavement were built to "get out of the mud". Many of these early pavements provided good performance without deterioration for more than 50 years. In the late 1950s, Iowa was faced with severe PCC pavement deterioration called D cracking. Research identified the cause of this deterioration as crushed limestone containing a bad pore system. Selective quarrying and ledge control has alleviated this problem. In 1990, cracking deterioration was identified on a three-year-old pavement on US 20 in central Iowa. The coarse aggregate was a crushed limestone with an excellent history of performance in PCC pavement. Examination of cores showed very few cracks through the coarse aggregate particles. The cracks were predominately confined to the matrix. The deterioration was identified as alkali-silica reactivity (ASR) by a consultant. To investigate the cause of the deterioration, the Iowa DOT and Iowa State University jointly purchased a high resolution, low vacuum Hitachi Scanning Electron Microscope (SEM) with an energy dispersion detector. Subsequent evaluation identified no concentration of silica gel (silicon-Si), but did identify substantial amounts of sulfur-S and aluminum-AL (assumed to be ettringite) in the air voids. Some of these voids have cracks radiating from them leading us to conclude that the ettringite filled voids were a center of pressure causing the crack. The ettringite in the voids, after being subjected to sodium chloride (NaCl), initially swells and then dissolves. This low vacuum SEM research of PCC pavement deterioration supports the following conclusions: (1) A low vacuum SEM and an energy dispersion detector are very important for proper evaluation of PCC pavement deterioration; (2) There are instances today where PCC pavement deterioration is mistakenly identified as ASR; (3) Ettringite initially expands when subjected to NaCl; and the ettringite filled voids are a center-of-pressure that cracks the PCC; and (4) The deterioration of some current premature PCC pavement distress locations is caused by factors related to the formation of excessive ettringite.

Francisco Cánovas Cobeño (1820-1904) : un catedrático de instituto que dignificaba la enseñanza.

Se realiza un breve repaso de la vida del geólogo y palentólogo Francisco Cánovas Cobeño, prestando atención principalmente a su labor como investigador, docente y escritor de libros de texto. Entre estos últimos se repasan títulos como 'Nociones de historia natural' (1862), 'Curso de historia natural' (1870), 'Cuadros de historia natural y Nociones elementales de organografía y fisiologías humanas y de higiene' (1895), 'Viajes por el término de Lorca, a través de los tiempos geológicos, con unos caballeros en desuso'(1874) o 'Historia de la ciudad de Lorca' (1890) .

A DIVERSIDADE RELIGIOSA NO ESPAÇO ESCOLAR ADVENTISTA DO ABCD PAULISTA

Tendo como pano de fundo a confessionalidade da rede adventista de educação presente de maneira marcante no espaço escolar e a intensa diversidade religiosa discente, esta pesquisa analisa a relação de possíveis tensões entre a confessionalidade escolar e a diversidade religiosa presente neste espaço. Leva em consideração o processo de modernidade causadora de importantes transformações na educação, na religião e na forma dos dois institutos se relacionarem. Levou-se em consideração o perfil socioeconômico e religioso dos alunos e possíveis tensões na recepção do religioso no espaço escolar adventista por parte dos discentes, inclusive por aqueles que se declaram adventistas. O espaço escolhido para esta pesquisa foi o de colégios adventistas localizadas no contexto do ABCD Paulista, que ofertam o Ensino Médio. Estas unidades escolares estão situadas nas cidades de Diadema, Santo André e São Caetano do Sul, cidades localizadas na mesma microrregião, mas com distintas realidades socioeconômicas
