    Affluent neighborhoods reduce excess risk of tooth loss among the poor

    The effect of neighborhood on health may vary according to the characteristics of the residents. We tested the hypothesis that, in affluent neighborhoods, low-income adults retain more teeth than their income-equivalent peers in poor neighborhoods. In 2003, the Adelaide Small Area Dental Study collected sociodemographic and tooth retention information from 2860 adults in 60 neighborhoods. Neighborhood socio-economic position was a census-based composite measure. Using multilevel modelling, we fitted a series of two-level random intercept variance component models. Findings revealed significant main effects for individual and neighborhood predictors and a significant interaction between neighborhood disadvantage and low income. In affluent areas, disparities in tooth retention were negligible, but in poor neighborhoods, substantial variation in tooth retention between individuals was found based on their level of income. Low-income adults appeared to benefit from living in affluent areas, while wealthier adults living in poor neighborhoods did not lose their oral health advantage.A.E. Sanders, G. Turrell and G.D.

    Terra e Luce. Dalla Gurfa al Roden Crater evoca i profondi e affascinanti misteri della natura dell'epoca preistorica e ci accoglie all'interno di un luogo in cui architettura, fisica, geologia e archeologia si fondono in un unico ambiente: luce, spazio e tempo, un solo luogo per conservare e sprigionare energie arcaiche e rare suggestioni. Il progetto dell'artista californiano, James Turrell nella cavità del Roden Crater, in Arizona, in continua trasformazione e le fotografie di Alessandro Belgiojoso della Gurfa, una delle più misteriose e caratteristiche testimonianze dell'architettura rupestre siciliana, raccontano di luoghi sconosciuti e tra di loro lontani, ma solo geograficamente. Le esperienze dei due artisti volte a stimolare i sensi, stupire ma anche indurre a sperimentare viaggi visionari e quasi impossibili non solo aprono un confronto tra le ricerche volte alla creazione di suggestioni ed effetti di luce, ma stabiliscono anche un legame tra le testimonianze dell'era preistorica in Sicilia e la ricerca artistica contemporanea di Turrell

    Does psychological stress mediate social deprivation in tooth loss?

    Copyright © 2007 International and American Associations for Dental ResearchIt is unclear which theoretical dimension of psychological stress affects health status. We hypothesized that both distress and coping mediate the relationship between socio-economic position and tooth loss. Cross-sectional data from 2915 middle-aged adults evaluated retention of < 20 teeth, behaviors, psychological stress, and sociodemographic characteristics. Principal components analysis of the Perceived Stress Scale (PSS) extracted ’distress’ (a = 0.85) and ’coping’ (a =0.83) factors, consistent with theory. Hierarchical entry of explanatory variables into age- and sex-adjusted logistic regression models estimated odds ratios (OR) and 95% confidence intervals [95% CI] for retention of < 20 teeth. Analysis of the separate contributions of distress and coping revealed a significant main effect of coping (OR = 0.7 [95% CI = 0.7–0.8]), but no effect for distress (OR = 1.0 [95% CI = 0.9–1.1]) or for the interaction of coping and distress. Behavior and psychological stress only modestly attenuated socio-economic inequality in retention of < 20 teeth, providing evidence to support a mediating role of coping.A.E. Sanders, G.D. Slade, G. Turrell, A.J. Spencer, and W. Marcene

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods
