This event history analysis explores factors driving the emergence over recent decades of comprehensive state-level student unit-record [SUR] systems, a potentially powerful tool for increasing student success. Findings suggest that the adoption of these systems is rooted in demand and ideological factors. Larger states, states with high…

The "29th Annual Report to Congress on the Implementation of the Individuals with Disabilities Education Act, 2007" follows the 2006--i.e., the 28th annual report--in sequence. The "29th Annual Report to Congress" is, however, the first to have three volumes. In the 28th and previous editions, volume 2 consisted of data tables…

The relationship between city population size and suicide rates rarely has been examined directly, though scholars often assume such a relationship exists based on studies of the association between suicide rates and urbanization (percent of the population living in cities) in various social contexts. In an effort to determine the basic…

This paper explores the relationships between population density, social interaction patterns, and morale in rural communities. It tests two apparently competing hypotheses concerning rural population density, social interaction patterns and overall levels of morale: one, that low (and rapidly declining) rural densities lead to feelings of…

The shape of the latent trait distribution can be of considerable theoretical and methodological importance. A simulation study was performed to examine the distribution of the likelihood ratio statistic that was used to test for normality via Johnson curves, the power to detect deviations from normality, and the estimation properties of the item…

In this paper a more accurate index of asymmetry is studied. Specifically, the use of the left and right variance is proposed and an index of asymmetry based on them is introduced. Several examples demonstrate its usefulness. The question of evaluating more accurately the dispersion of data about the average emerges in all non-symmetric…

Context: Physician supply is anticipated to fall short of national requirements over the next 20 years. Rural areas are likely to lose relatively more physicians. Policy makers must know how to anticipate what changes in distribution are likely to happen to better target policies. Purpose: To determine whether there was a significant flow of…

A total of 128 students at a public high school in Oakland, California, participated in the study. Of these early and middle adolescents, 86 were Chinese American and 42 were Southeast Asian American. They completed the…

The technique of distance sampling is widely used to monitor biological populations. This paper documents an in-class activity to introduce students to the concepts and the mechanics of distance sampling in a simple situation that is relevant to their own experiences. Preparation details are described. Variations and extensions to the activity are…

The Office of Native American Programs serving all American Indians has primary responsibility for developing policy, legislative proposals and guidance, and for providing staff advice to the Office of the Secretary on matters of poverty relative to urban and reservation Indians. (JC)

An attempt to project the 1981 total Ontario population for each municipality in each county and district was made to provide some guidelines in projections of school enrollment, especially in those areas of apparent rapid growth or even of decline in total population. The process followed was the preparation of a preliminary estimate of the 1981…

The Bureau of Census data on American Indians are inaccurate on age, sex, and total population as published. What is needed includes: complete count data on American Indian total population, sex distribution, and age distribution for states and their subdivisions, Indian reservations, and American Indian ethnic and linguistic groups, rather than…

Census 2000 counted 281.4 million U.S. residents, of whom 12.5 percent were Hispanic. Mexicans represented 7.3 percent, Puerto Ricans 1.2 percent, Cubans 0.4 percent, and other Hispanics 3.6 percent of the population. Another 3.8 million Hispanics were counted in the Commonwealth of Puerto Rico. The Hispanic population increased by 57.9 percent…
