Spatiotemporal and Socioeconomic Risk Factors for Dengue at the Province Level in Vietnam, 2013-2015: Clustering Analysis and Regression Model.

Dengue is a serious infectious disease threat in Vietnam, but its spatiotemporal and socioeconomic risk factors are not currently well understood at the province level across the country and on a multiannual scale. We explore spatial trends, clusters and outliers in dengue case counts at the province level from 2011-2015 and use this to extract spatiotemporal variables for regression analysis of the association between dengue case counts and selected spatiotemporal and socioeconomic variables from 2013-2015. Dengue in Vietnam follows anticipated spatial trends, with a potential two-year cycle of high-high clusters in some southern provinces. Small but significant associations are observed between dengue case counts and mobility, population density, a province's dengue rates the previous year, and average dengue rates two years previous in first and second order contiguous neighbours. Significant associations were not found between dengue case counts and housing pressure, access to electricity, clinician density, province-adjusted poverty rate, percentage of children below one vaccinated, or percentage of population in urban settings. These findings challenge assumptions about socioeconomic and spatiotemporal risk factors for dengue, and support national prevention targeting in Vietnam at the province level. They may also be of wider relevance for the study of other arboviruses, including Japanese encephalitis, Zika, and Chikungunya

The Accuracy and Power of Sex, Social Class, and Ethnic Stereotypes: A Naturalistic Study in Person Perception

This research examined the accuracy and power of sex, social class, and ethnic stereotypes in person perception. Participants included 49 to 56 teachers and nearly 2,000 students in seventh-grade public school math classes. Results indicated that teacher perceptions regarding achievement and motivation differences between girls and boys, lower- and upper-class students, and African American and White students were mostly accurate. Results also showed that although teachers generally relied on students' personal characteristics to form their perceptions, they occasionally relied on stereotypes. We discuss these results in terms of the classic view that stereotypes are inaccurate, rigid, exaggerated, and exert powerful effects on person perception.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68982/2/10.1177_01461672982412005.pd
