Impact on Student Achievement of Teacher Participation in K-8 Mathematics Professional Development

The purpose of this study is to determine the impact on student achievement of elementary school teachers who participated in professional development in the content area of mathematics. Teachers participated in professional development courses and have accumulated a range from three to eighteen total credits from the summers of 1998 through 2007. The impact is measured by student achievement data collected on standardized tests

A Fundamental Comparison of International Real Estate Returns

This study analyzes commercial real estate returns in Australia, Canada, the United Kingdom, and the United States over the period 1985-95, from the perspective of a U.S. investor. Because national indices can consist of differing property mixes, this study separately analyzes the office, retail, and warehouse sectors. Moreover, these analyses also convert total returns into their fundamental components: initial yield, growth in income, and shifts in capitalization rates. The paths of currency-adjusted income and asset values and, therefore, capitalization rates are also presented. Generally speaking, the fundamental components of retail returns across the four countries exhibit greater divergence than the office and warehouse sectors. It is interesting that the U.S. property sectors showed the worst performance, while the Australian retail and the British office and warehouse sectors were the best performers (both before and after currency adjustments). Additionally, the currency-adjusted Australian returns were adversely effected by exchange rate movements, while the British returns were positively effected. Lastly, the correlation of the quarterly percentage change in income was generally lower and less statistically significant that the correlation patterns observed among the other components of return. This might suggest that more idiosyncratic risk can be found in the real estate space markets (as proxied by income changes) than in the real estate capital markets (as proxied by the pricing of the income--that is, capitalization rates), which appear to be more globally influenced.

ALDH2*2 and peer drinking in East Asian college students

Background: The ALDH2*2 allele (A-allele) at rs671 is more commonly carried by Asians and is associated with alcohol-related flushing, a strong adverse reaction to alcohol that is protective against drinking. Social factors, such as having friends who binge drink, also contribute to drinking in Asian youth. Objectives: This study examined the interplay between ALDH2*2, peer drinking, and alcohol consumption in college students. We hypothesized that the relationship between ALDH2*2 and standard grams of ethanol per month would vary based on the level of peer drinking. Methods: Subjects (N = 318, 63.25% female) were East Asian college students in the United States who reported drinking alcohol. Data were from the freshman year of a university survey that included a saliva DNA sample. ALDH2*2 status was coded ALDH2*2(+) (A/G and A/A genotypes) and ALDH2*2(−) (G/G genotype). Peer drinking was students’ perception of how many of their friends “got drunk”. Results: Main effects of ALDH2*2(−) and having more friends who got drunk were associated with greater alcohol consumption. The ALDH2*2 × peer drunkenness interaction showed a stronger positive association with alcohol consumption for ALDH2*2(−) versus ALDH2*2(+) at increasing levels of peer drunkenness. Follow-up comparisons within each peer drunkenness level identified significantly higher alcohol consumption for ALDH2*2(−) compared to ALDH2*2(+) at the all friends got drunk level. Conclusion: There was evidence of a stronger effect for ALDH2*2(−) compared to ALDH2*2(+) with greater alcohol use when students were more exposed to peer drinking. Findings contribute to a growing literature on the interrelationships between genetic influences and more permissive environments for alcohol consumption

Can financial incentives reduce juvenile confinement levels? An evaluation of the Redeploy Illinois program

Purpose Assessments of ongoing fiscal restructuring of juvenile justice system processes and the impact such restructuring has on juvenile incarceration rates are limited. When impacts of fiscal restructuring efforts have been assessed, researchers have focused on systemic, macro level changes in incarceration rates but avoided more focused, micro level impacts. This study fills this knowledge gap by examining the recent implementation of the Redeploy Illinois program in two pilot sites. In the Redeploy Illinois program, financial incentives were provided to select counties to develop community based alternatives to incarceration. The goal was to alleviate over reliance on state funded residential facilities for evaluation and confinement purposes. Methods Agency data were analyzed using qualitative methods to examine the effects of this change. Results Results of this study demonstrated that counties participating in the pilot test of the Redeploy Illinois program were able to reduce their levels of juvenile commitment to the state. Peoria County exceeded their reduction benchmark for all but two years, and St. Clair County well exceed their reduction benchmark for all full calendar years subsequent to implementation. Conclusions Findings are consistent with the limited literature exploring fiscal restructuring efforts designed to reduce county levels juvenile commitments

Parsimonious continuous time random walk models and kurtosis for diffusion in magnetic resonance of biological tissue

In this paper, we provide a context for the modeling approaches that have been developed to describe non-Gaussian diffusion behavior, which is ubiquitous in diffusion weighted magnetic resonance imaging of water in biological tissue. Subsequently, we focus on the formalism of the continuous time random walk theory to extract properties of subdiffusion and superdiffusionthrough novel simplifications of the Mittag-Leffler function. For the case of time-fractional subdiffusion, we compute the kurtosis for the Mittag-Leffler function, which provides both a connection and physical context to the much-used approach of diffusional kurtosis imaging. We provide Monte Carlo simulations to illustrate the concepts of anomalous diffusion as stochastic processes of the random walk. Finally, we demonstrate the clinical utility of the Mittag-Leffler function as a model to describe tissue microstructure through estimations of subdiffusion and kurtosis with diffusion MRI measurements in the brain of a chronic ischemic stroke patient
