Title of dissertation: INDIVIDUALAND CLASSROOMLEVEL SOCIAL SUPPORT AND CLASSROOM BEHAVIOR IN MIDDLE SCHOOL Shannon Lea Russell, Doctor of Philosophy, 2012 Dissertation directed by: Professor Kathryn R. Wentzel, Department of Human Development and Quantitative Methodology This study investigated relations between middle school students’ perceptions of social support from their teachers and peers...

We present new high-quality near-infrared photometry of 10 Galactic Globular Clusters spanning a wide metallicity range (−2.126[Fe/H]6 − 0.49): five clusters belong to the Halo (namely, NGC 288, NGC 362, NGC 6752, M 15 and M 30) and five (namely, NGC 6342, NGC 6380, NGC 6440, NGC 6441 and NGC 6624) to the Bulge. By combining J, H and K observations with optical data, we constructed Colour-Magni...

Recently, Baker and Norine have proven a Riemann-Roch theorem for finite graphs. We extend their results to metric graphs and thus establish a Riemann-Roch theorem for divisors on (abstract) tropical curves. Tropical algebraic geometry is a recent branch of mathematics that establishes deep relations between algebro-geometric and purely combinatorial objects. Ideally, every construction and the...

Introduction: Mineralogy is the key to determining the compositional history of the asteroids and to determining the genetic relationships between the asteroids and meteorites. The most sophisticated remote mineralogical characterizations involve the quantitative extraction of specific diagnostic parameters from reflectance spectra and the use of quantitative interpre-tive calibrations to deter...

The regional climate model HIRHAM has been applied over the Asian continent from 0oN to 50oN and 42oE to 110oE to simulate the Indian monsoon circulation under past and present-day conditions. The model is driven at the lateral and lower boundaries by the atmospheric output fields of the global coupled Earth system model ECHAM5JSBACH/MPIOM for 44-years-long time slices during the mid-Holocene a...

The " Supercritical Pile " is a very economical GRB model that provides for the efficient conversion of the energy stored in the protons of a Relativistic Blast Wave (RBW) into radiation and at the same time produces-in the prompt GRB phase, even in the absence of any particle acceleration-a spectral peak at energy ∼ 1 MeV. We extend this model to include the evolution of the RBW Lorentz factor...

two dimensional slope profile morphometric investigation in a part of the land failure prone garhwal region of the lesser himalaya, tehri district, u. p., india, indicates that the landslip morphology is closely related to the dominant movement processes active in this terrain. technique developed for the morphometric analysis of landslips involves the use of five morphometric indices. each ind...

Many slope filtrations occur in algebraic geometry, asymptotic analysis, ramification theory, p-adic theories, geometry of numbers... These functorial filtrations, which are indexed by rational (or sometimes real) numbers, have a lot of common properties. We propose a unified abstract treatment of slope filtrations, and survey how new ties between different domains have been woven by dint of de...

We have applied the MCS image deconvolution algorithm (Magain et al. 1998) to HST/WFPC2 V , I data of three M 31 bulge globular clusters (G170, G177, and G198) and control fields near each cluster. All three clusters are clearly detected, with an increase in stellar density with decreasing radius from the cluster centers; this is the first time that stars have been resolved in bulge clusters in...
