The application of modelling to social learning in monkey populations has been a neglected topic. Recently, however, a number of statistical, simulation and analytical approaches have been developed to help examine social learning processes, putative traditions, the use of social learning strategies and the diffusion dynamics of socially…

Calvin Lunsford Beale was born in Washington, DC, on June 6, 1923, and passed away at age 85 on September 2, 2008. He was a city boy born and bred, and while he "never wanted to live in a rural area" he became one of the most astute observers of rural America in the latter half of the twentieth century. Calvin spent the majority of his…

We propose a nonparametric (or distribution-free) procedure for testing the equality of several population variances (or scale parameters). The proposed test is a modification of Bakir's (1989, Commun. Statist., Simul-Comp., 18, 757-775) analysis of means by ranks (ANOMR) procedure for testing the equality of several population means. A proof is…

This article presents the state education finance and governance profile of Arkansas. Arkansas has 254 school districts, which operate 1,114 schools. More than two thirds (68.4%) of all schools are Title I schools. All school districts in Arkansas receive foundation funding--a set amount of money per student. In addition to the foundation funding…

Environmental social scientists debate whether or not modern development reduces society's impact on the biosphere. The empirical research informing the discussion has not yet adequately examined the social determinants of municipal solid-waste (MSW) generation, an increasingly relevant issue, both ecologically and sociologically. A primary…

Growing accountability pressures, accompanied by a lack of readily accessible measures of institutional performance, have led to an increasing focus on graduation rates. Although previous research has illuminated myriad factors influencing students' likelihood of educational success, it has not paid adequate attention to how state contexts may…

People have always been fascinated with investigating their home--the Earth. For centuries, maps have stirred imaginations and inspired explorations of the unknown. Maps are a rich source of information, showing spatial relationships between climate, vegetation, population, landforms, river systems, land use, soils, natural hazards, and much more.…

Empirical studies estimating the effect of private school competition on student outcomes commonly use the share of Catholics in the local population as an instrument for private school competition. I show that this is not a valid instrument since it is endogenous to private school competition and suggest using instead the local share of Catholics…

This article provides the theory and application of the 2-stage maximum likelihood (ML) procedure for structural equation modeling (SEM) with missing data. The validity of this procedure does not require the assumption of a normally distributed population. When the population is normally distributed and all missing data are missing at random…

This paper uses feminist work on diaspora and postcolonial theory to examine the ways in which women serial migrants, who as children left the Caribbean to join their parents in the UK, experienced racialised, gendered intersections in the "contact zone" of school. Drawing on narrative accounts from women serial migrants the paper argues…

The relationship between educational attainment and economic outcomes is shaped by a variety of educational experiences, including field of training, length of time spent in school, and level of attainment. This report explores the relationship between educational attainment, field of training, and eventual occupation and earnings. The report also…

Children of immigrant backgrounds--children who are immigrants themselves or were born to immigrant parents--are the largest segment of growth in the U.S. school population. In this exploratory interdisciplinary analysis, Filindra, Blanding, and Garcia Coll ask whether the context of policy and political receptivity, even when they are not…

This paper describes a statistical study of the contribution of theories previously offered by economists to explain differences in the degree of urban decentralization in the U.S. The focus is on a relative comparison of the influence of auto reliance. A regression analysis reveals that a 10 percent reduction in the percentage of households…

Context: There is little information about how increases in the rehabilitation therapist workforce have been distributed over the nation. There is evidence that rural areas continue to face a shortage of trained rehabilitation providers. There has also been little attention to therapist distribution in non-rural settings where health professionals…

Background: Diffusion tensor imaging (DTI) has revealed microstructural aspects of adolescent brain development, the cognitive correlates of which remain relatively uncharacterized. Methods: DTI was used to assess white matter microstructure in 18 typically developing adolescents (ages 16-18). Fractional anisotropy (FA) and mean diffusion (MD)…
