Esl Placement And Schools: Effect On Immigrant Achievement, Rebecca Callahan, Lindsey Wilkinson, Chandra Muller, Michelle Frisco

Sociology Faculty Publications and Presentations

In this study, the authors explore English as a Second Language (ESL) placement as a measure of how schools label and process immigrant students. Using propensity score matching and data from the Adolescent Health and Academic Achievement Study and the National Longitudinal Study of Adolescent Health, the authors estimate the effect of ESL placement on immigrant achievement. In schools with more immigrant students, the authors find that ESL placement results in higher levels of academic performance; in schools with few immigrant students, the effect reverses. This is not to suggest a one-size-fits-all policy; many immigrant students, regardless of school composition, …

A Plesiosaur Containing An Ichthyosaur Embryo As Stomach Contents From The Sundance Formation Of The Bighorn Basin, Wyoming, F. Robin O’Keefe, Hallie P. Street, Jean Pierre Cavigelli, John J. Socha, R. Dennis O'Keefe

Biological Sciences Faculty Research

Herein we report the discovery of an ichthyosaur embryo from the Upper Member of the Sundance Formation (Oxfordian) of the Bighorn Basin, Wyoming. The specimen is the first known ichthyosaur embryo from the Upper Jurassic, and is the first Jurassic ichthyosaur embryo from North America. The embryo was discovered in close association with the abdomen of an articulated partial plesiosaur skeleton, and several lines of evidence support the interpretation of the embryo as plesiosaur stomach contents. The small size and extremely poor ossification of the embryo indicate that the animal was probably not a neonate. Although the taxonomic affinities of …

Osteology Of The Cryptocleidoid Plesiosaur Tatenectes Laramiensis, With Comments On The Taxonomic Status Of The Cimoliasauridae, F. Robin O’Keefe, Hallie P. Street

Biological Sciences Faculty Research

Recent field work in the Bighorn Basin, Wyoming has recovered significant new material of the plesiosaur Tatenectes laramiensis. The majority of cryptocleidoid plesiosaurs have been recovered from Middle and Upper Jurassic units (Oxford and Kimmeridge Clays, respectively) in the United Kingdom, but Tatenectes laramiensis is one of at least two cryptocleidoids known from the Upper Sundance Member of the Sundance Formation (Oxfordian) of North America. Although poorly known, they bear directly on both the phylogeny and biogeography of the cryptocleidoid plesiosaurs. Here we describe new fossil material of Tatenectes, and reevaluate the phylogenetic position of this genus based on all …

Beheading First: On Nabokov's Translation Of Lewis Carroll, Victor Fet

Utility Of Free To Total Psa Ratio In The Prediction Of Prostate Cancer In Patients With Intermediate Total Psa Levels And Negative Digital Rectal Examination, Muthoni .J .F. Kirimi

Master of Medicine in Anatomic Pathology

Background: Prostate carcinoma is among the top 5 cancers occurring in Kenyan men. Prostate-specific antigen (PSA) is currently the most important biochemical marker for the diagnosis of prostate cancer and its widespread use as a serum tumor marker has revolutionized the management of patients with prostate cancer. The identification of early prostate cancer is vital in the management of especially men who have mild or vague prostatic symptoms. The most basic and important proxy for determining the need for a biopsy in both symptomatic and asymptomatic(screened) patients is the serum prostatic specific antigen (PSA).If a patients PSA level is above …

Intermediate-Complexity Biological Modeling Framework For Nutrient Cycling In Lakes Based On Physical Structure, Michael Clay Rigley

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Mathematical models for the change in concentration of total dissolved nitrogen (TDN) in mountain lakes are developed based on the dynamics of coupled, well-mixed containers. Each includes a stratified lake structure without the complexity of a full fluid model. A lake is divided into a suite of compartments based on physical structure: warm upper layer (epilimnion), cold inflow and insertion layer (metalimnion), cold lower layer (hypolimnion), and a warm shallow shelf. With the compartments as the framework and literature values for uptake rates, death rates, half-saturation constants, and sinking rates, systems of equations are written for three models. The first …

Ambient Dose Equivalent Versus Effective Dose For Quantifying Stray Radiation Exposures To A Patient Receiving Proton Therapy For Prostate Cancer, Jonas D. Fontenot, Phillip T. Taddei, Yuanshui Zheng, Dragan Mirkovic, Wayne D. Newhauser

Faculty Publications

The purpose of this study was to evaluate the suitability of the quantity ambient dose equivalent H*(10) as a conservative estimate of effective dose E for estimating stray radiation exposures to patients receiving passively scattered proton radiotherapy for cancer of the prostate. H*(10), which is determined from fluence free-in-air, is potentially useful because it is simpler to measure or calculate because it avoids the complexities associated with phantoms or patient anatomy. However, the suitability of H*(10) as a surrogate for E has not been demonstrated for exposures to high-energy neutrons emanating from radiation treatments with proton beams. The suitability was …

Reducing Stray Radiation Dose For A Pediatric Patient Receiving Proton Craniospinal Irradiation, Phillip J. Taddei, Dragan Mirkovic, Jonas D. Fontenot, Annelise Giebeler, Yuanshui Zheng, Uwe Titt, Shiao Woo, Wayne D. Newhauser

Faculty Publications

The aim of this study was to quantify stray radiation dose from neutrons emanating from a proton treatment unit and to evaluate methods of reducing this dose for a pediatric patient undergoing craniospinal irradiation. The organ equivalent doses and effective dose from stray radiation were estimated for a 30.6-Gy treatment using Monte Carlo simulations of a passive scattering treatment unit and a patient-specific voxelized anatomy. The treatment plan was based on computed tomography images of a 10-yr-old male patient. The contribution to stray radiation was evaluated for the standard nozzle and for the same nozzle but with modest modifications to …

A Track-Repeating Algorithm For Fast Monte Carlo Dose Calculations Of Proton Radiotherapy, Pablo Yepes, Sharmalee Randeniya, Phillip J. Taddei, Wayne D. Newhauser

Faculty Publications

Monte Carlo codes are utilized for accurate dose calculations in proton radiation therapy research. While they are superior in accuracy to commonly used analytical dose calculations, they require significantly longer computation times. The aim of this work is to characterize a Monte Carlo track-repeating algorithm to increase computation speed without compromising dosimetric accuracy. The track-repeating approach reduced the CPU time required for a complete dose calculation in voxel- ized patient anatomy by more than two orders of magnitude, while on average reproducing the results from the traditional Monte Carlo approach within 4% dose difference and within 1-mm distance to agreement.

Sos1 And Halophytism., Dong Ha Oh, Ali Zahir, Dae Jin Yun, Ray A. Bressan, Hans J. Bohnert

Faculty Publications

Much is already known about the function and functioning of the three genes that make up the SOS (Salt-Overly-Sensitive) pathway in plants, but recent studies indicate that the linkage between external increases in salinity and stress protection provided by genes SOS1, SOS2 and SOS3 is more complex than previously appreciated. It has recently been shown that the engineered reduced expression of the sodium/proton antiporter SOS1 affected several pathways indicating a role for SOS1 that exceeds its known function as an antiporter. Interference with expression of SOS1, characterized as a sodium/proton antiporter in the halophyte Thellungiella salsuginea converted Thellungiella into an …

Phylogenetic Relationships Among Seed Plants: Persistent Questions And The Limits Of Molecular Data, Sarah Mathews

Faculty Publications

Trees inferred from DNA sequence data provide only limited insight into the phylogeny of seed plants because the living lineages (cycads, Ginkgo, conifers, gnetophytes, and angiosperms) represent fewer than half of the major lineages that have been detected in the fossil record. Nevertheless, phylogenetic trees of living seed plants inferred from sequence data can provide a test of relationships inferred in analyses that include fossils. So far, however, significant uncertainty persists because nucleotide data support several conflicting hypotheses. It is likely that improved sampling of gymnosperm diversity in nucleotide data sets will help alleviate some of the analytical issues encountered …

Adipose Tissue Collagen Vi In Obesity, Magdalena Pasarica, Barbara Gowronska-Kozak, David Burk, Isabel Remedios, David Hymel, Jeff Gimble, Eric Ravussin, George A. Bray, Steven R. Smith

Faculty Publications

Objectives: Basic science studies show that the extracellular matrix of adipose tissue, mainly represented by collagen VI, is dysfunctional in obesity and contributes to the development of the metabolic syndrome. We hypothesized in humans that increased collagen VI α3-subunit (COL6A3) mRNAis associated with adipose tissue macrophage chemotaxis and inflammation and that weight gain is accompanied by changes in the expression of COL6A3. Research Design and Methods: Adipose tissue biopsies were obtained from a cross-sectional study (n = 109), an overfeeding study (n = 9), and a pioglitazone treatment study (n = 14). Adipose tissue gene expression was measured by quantitative …

Recent breakthroughs in the determination of the crystal structures of G protein-coupled receptors (GPCRs) have provided new opportunities for structure-based drug design strategies targeting this protein family. With the aim of evaluating the current status of GPCR structure prediction and ligand docking, a community-wide, blind prediction assessment - GPCR Dock 2008 - was conducted in coordination with the publication of the crystal structure of the human adenosine A2Areceptor bound to the ligand ZM241385. Twenty-nine groups submitted 206 structural models before the release of the experimental structure, which were evaluated for the accuracy of the ligand binding mode and the overall …

Differential Gene Expression Of Resistant And Susceptible Sweetpotato Plants After Infection With The Causal Agents Of Sweet Potato Virus Disease, Cecilia E. Mcgregor, Douglas W. Miano, Don R. Labonte, Mary Hoy, Chris A. Clark, Guilherme J.M. Rosa

Faculty Publications

Sweet potato virus disease (SPVD) is one of the most devastating diseases affecting sweetpotato (Ipomoea batatas), an important food crop in developing countries. SPVD develops when sweetpotato plants are dually infected with sweet potato feathery mottle virus (SPFMV) and sweet potato chlorotic stunt virus (SPCSV). To better understand the synergistic interaction between these viruses, global gene expression was previously studied in the susceptible cultivar Beauregard. In the current study, global gene expression between SPVD-affected plants and virus-tested control plants (VT) were compared in 'Beauregard' (Bx) and resistant 'NASPOT 1' (Nas) sweetpotato cultivars at 5, 9, 13, and 17 days post …

Reaction Of Potato Cultivars To Streptomyces Scabies, Causal Agent Of Deep Common Scab, Ivan Herman Fischer, Ana Paula Matoso Teixeira, Leonardo Toffano, Ely Oliveira Garcia

Faculty Publications

This work aimed to characterize the isolates of Streptomyces, responsible for deep common scab symptoms in potato, according to morphological and physiological criteria; to evaluate the resistance of potato cultivars to the disease and the aggressiveness of bacterium isolates. The Streptomyces isolates presented gray coloration on yeast extract and malt medium and spiral spore chains, produced on aerial hyphae. Production of melanina occurred in tirosine-agar medium and the utilization of eight recommended carbon sources. These properties correspond to the S. scabies species. Healthy potato seeds of six cultivars were planted in substratum infested with six isolates of S. scabies separately, …

Stabilization In A Two-Species Chemostat With Monod Growth Functions, Frédéric Mazenc, Michael Malisoff, Jérôme Harmand

Faculty Publications

We design feedback controllers for two species chemostats so that an equilibrium with arbitrary prescribed positive species concentrations becomes globally asymptotically stable. We use a new global explicit strict Lyapunov function construction, which allows us to quantify the effects of disturbances using the input-to-state stability paradigm.We assume that only a linear combination of the species concentrations is known. We illustrate our approach using a numerical example. © 2009, IEEE. All rights reserved.

Sperm Cryopreservation Of A Live-Bearing Fish, Xiphophorus Couchianus: Male-To-Male Variation In Post-Thaw Motility And Production Of F1 Hybrid Offspring, Huiping Yang, Leona Hazlewood, Ronald B. Walter, Terrence R. Tiersch

Faculty Publications

Fishes of the genus Xiphophorus are well-studied biomedical research models, and some species, such as X. couchianus, are currently listed as endangered in the wild. Sperm cryopreservation in these live-bearing fishes has begun recently. Thus far, live young have been produced with cryopreserved sperm only in one species (Xiphophorus helleri). In this study, the goal was to develop a practical protocol for sperm cryopreservation of Xiphophorus couchianus, and to produce live young with cryopreserved sperm. Sperm were collected by crushing of testis in Hanks' balanced salt solution at an osmolality of 500 mOsmol/kg (HBSS500), and were cryopreserved with 14% glycerol …

Current Status Of Sperm Cryopreservation In Biomedical Research Fish Models: Zebrafish, Medaka, And Xiphophorus, Huiping Yang, Terrence R. Tiersch

Aquarium fishes are becoming increasingly important because of their value in biomedical research and the ornamental fish trade, and because many have become threatened or endangered in the wild. This review summarizes the current status of sperm cryopreservation in three fishes widely used in biomedical research: zebrafish, medaka, and live-bearing fishes of the genus Xiphophorus, and will focus on the needs and opportunities for future research and application of cryopreservation in aquarium fish. First, we summarize the basic biological characteristics regarding natural habitat, testis structure, spermatogenesis, sperm morphology, and sperm physiology. Second, we compare protocol development of sperm cryopreservation. Third, …

Antifungal And Insecticidal Activity Of Two Juniperus Essential Oils, David E. Wedge, Nurhayat Tabanca, Blair J. Sampson, Christopher Werle, Betul Demirci, K. Husnu Can Baser, Peng Nan, Jia Duan, Zhijun Liu

Faculty Publications

Essential oils of two Tibetan Junipers Juniperus saltuaria and J. squamata var. fargesii (Cupressaceae) were obtained by distilling dried leaves and branches using a Clevenger apparatus. Sixty-seven compounds from J. saltuaria and 58 from J. squamata var. fargesii were identified by gas chromatography-mass spectrometry (GC-MS). Both essential oils contained similar ratios of four abundant monoterpenoids: 44 and 35% sabinene, 13 and 9% elemol, 8 and 7% terpinen-4-ol, and 4 and 17% α-pinene, respectively. These oils had antifungal activity based on a direct bioautography assay of Colletotrichum acutatum, C. fragariae, and C. gloeosporioides, and insecticidal activity based on serial-time mortality bioassay …

Twenty Years Of Understorey Bird Extinctions From Amazonian Rain Forest Fragments: Consistent Trends And Landscape-Mediated Dynamics, Philip C. Stouffer, Cheryl Strong, Luciano N. Naka

Faculty Publications

Aim: We analysed presence/absence data for understorey bird species in rain forest fragments sampled from 1979 through 2001. Here we consider extinctions between 1992, when most fragments had been isolated for at least 8 years, and 2001. Our objectives were to determine whether high extinction rates documented soon after isolation continued through up to 20 years after isolation, and to examine fragment size and landscape effects on extinction. Location: Biological Dynamics of Forest Fragments Project, near Manaus, Brazil. Methods: Through 1992, birds were surveyed with standardized mist net sampling in ten 1- to 100-ha fragments. We repeated the mist net …
