Characterization Of Planar Wave Guides By Angle-Dependent Excitation Of Guided Modes, Edward D. Lunde

Physics

In this project a high resolution rotation stage was used to measure the angle of coupling of light into planar waveguide modes. Control of the stage and acquisition of light intensity data was done using the commercially available programming environment, MATLAB. Reliable, repeatable excitation of modes was done using prism coupling. We also investigated coupling using a surface grating on the waveguide.

Tracking Transmission Of Apicomplexan Symbionts In Diverse Caribbean Corals, Nathan L. Kirk, Raphael Ritson-Williams, Mary Alice Coffroth, Margaret W. Miller, Nicole D. Fogarty, Scott R. Santos

Marine & Environmental Sciences Faculty Articles

Symbionts in each generation are transmitted to new host individuals either vertically (parent to offspring), horizontally (from exogenous sources), or a combination of both. Scleractinian corals make an excellent study system for understanding patterns of symbiont transmission since they harbor diverse symbionts and possess distinct reproductive modes of either internal brooding or external broadcast spawning that generally correlate with vertical or horizontal transmission, respectively. Here, we focused on the under-recognized, but apparently widespread, coral-associated apicomplexans (Protista: Alveolata) to determine if symbiont transmission depends on host reproductive mode. Specifically, a PCR-based assay was utilized towards identifying whether planula larvae and reproductive …

Community-Level Response To Habitat Structure Manipulations: An Experimental Case Study In A Tropical Ecosystem, Emily A. Kalnicky, Karen H. Beard, Mark W. Brunson

Wildland Resources Faculty Publications

Across the globe, environmental change is resulting in novel ecosystems that have altered habitat structure and functioning. Research is needed to understand how changes in habitat structure in these new ecosystems impact community interactions, especially when these manipulations are being proposed to reduce invasive species. We conducted an experiment in Hawaii to determine how changes in habitat structure, represented by leaf litter and understory vegetation, affect the abundance of an invasive generalist predator, the coqui frog (Eleutherodactylus coqui) and its potential prey (invertebrates). This study consisted of four treatments: two vegetation treatments (50% and 100% removal of vegetation with diameter …

Re-Examining The Electronic Structure Of Germanium: A First-Principle Study, C. E. Ekuma, M. Jarrell, J. Moreno, D. Bagayoko

Faculty Publications

We report results from an efficient, ab initio method for self-consistent calculations of electronic and structural properties of Ge. Our non-relativistic calculations employed a GGA potential and LCAO formalism. The distinctive feature of our computations stem from the use of Bagayoko-Zhao-Williams-Ekuma- Franklin method. Our results are in agreement with experimental ones where the latter are available. In particular, our theoretical, indirect band gap (EgΓ-L) of 0.65 eV, at the experimental lattice constant of 5.66 Å, is in excellent agreement with experiment. Our predicted, equilibrium lattice constant is 5.63 Å, with corresponding EgΓ-L of 0.65 eV and a bulk modulus of …

Levels of low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, triglycerides and total cholesterol are heritable, modifiable risk factors for coronary artery disease. To identify new loci and refine known loci influencing these lipids, we examined 188,577 individuals using genome-wide and custom genotyping arrays. We identify and annotate 157 loci associated with lipid levels at P < 5 × 10 -8, including 62 loci not previously associated with lipid levels in humans. Using dense genotyping in individuals of European, East Asian, South Asian and African ancestry, we narrow association signals in 12 loci. We find that loci associated with blood lipid levels are often associated with cardiovascular and metabolic traits, including coronary artery disease, type 2 diabetes, blood pressure, waist-hip ratio and body mass index. Our results demonstrate the value of using genetic data from individuals of diverse ancestry and provide insights into the biological mechanisms regulating blood lipids to guide future genetic, biological and therapeutic research. © 2013 Nature America, Inc.

Children's Marking Of Verbal -S By Nonmainstream English Dialect And Clinical Status, Lesli H. Cleveland, Janna B. Oetting

Faculty Publications

Purpose: Children's marking of verbal -s was examined by their dialect (African American English [AAE] vs. Southern White English [SWE]) and clinical status (specific language impairment [SLI] vs. typically developing [TD]) and as a function of 4 linguistic variables (verb regularity, negation, expression of a habitual activity, and expression of historical present tense). Method: The data were language samples from 57 six-year-olds who varied by their dialect and clinical status (AAE: SLI = 14, TD = 12; SWE: SLI = 12, TD = 19). Results: The AAE groups produced lower rates of marking than did the SWE groups, and the …

Validity Of Boston Marathon Qualifying Times, Paul M. Vanderburgh

Health and Sport Science Faculty Publications

Purpose: To assess the validity of Boston Marathon qualifying (BMQ) standards for men and women. Methods: Percent differences between BMQ and current world records (WR) by sex and age group were computed. WR was chosen as the criterion comparison because it is not confounded by intensity, body composition, lifestyle, or environmental factors. A consistent difference across age groups would indicate an appropriate slope of the age-vs-BMQ curve. Inconsistent differences were corrected by adjusting BMQ standards to achieve a uniform percentage difference from WR. Results: BMQ standards for men were consistently ~50% slower than WR (mean 51.5% ± …

Test For Intraclass Correlation Coefficient Under Unequal Family Sizes, Madhusudan Bhandary, Koji Fujiwara

Journal of Modern Applied Statistical Methods

Three tests are proposed based on F-distribution, Likelihood Ratio Test (LRT) and large sample Z-test for intraclass correlation coefficient under unequal family sizes based on a single multinormal sample. It has been found that the test based on F-distribution consistently and reliably produces results superior to those of Likelihood Ratio Test (LRT) and large sample Z-test in terms of size for various combinations of intraclass correlation coefficient values. The power of this test based on F-distribution is competitive with the power of the LRT and the power of Z-test is slightly better than the powers of F-test and LRT when …

Case-Control Studies With Jointly Misclassified Exposure And Confounding Variables, Tze-San Lee

Journal of Modern Applied Statistical Methods

The issue of 2 × 2 × 2 case-control studies is addressed when both exposure and confounding variables are jointly misclassified. Two scenarios are considered: the classification errors of exposure and confounding variables are independent or not independent. The bias-adjusted cell probability estimates which account for the misclassification bias are presented. The effect of misclassification on the measure of crude odds ratio either unstratified or stratified by the confounder, Mantel-Haenszel summary odds ratio, the confounding component in the crude odds ratio, the first and second order multiplicative interaction are assessed through the sensitivity analysis from using the data on the …

Akaike Information Criterion To Select The Parametric Detection Function For Kernel Estimator Using Line Transect Data, Omar Eidous, Samar Al-Salman

Journal of Modern Applied Statistical Methods

Among different candidate parametric detection functions, it is suggested to use Akaike Information Criterion (AIC) to select the most appropriate one of them to fit line transect data. Four different detection functions are considered in this paper. Two of them are taken to satisfy the shoulder condition assumption and the other two estimators do not satisfy this condition. Once the appropriate detection function is determined, it also can be used to select the smoothing parameter of the nonparametric kernel estimator. For a wide range of target densities, a simulation results show the reasonable and good performances of the …

We calculated magnetic exchange constants and magnetocaloric properties of Ni₂Mn_1-xCu_xGa Heusler alloys by ab initio and Monte Carlo methods. The ab initio study of the influence of the Cu excess x on the strength of magnetic interactions revealed that Cu weakens Mn-Ni interaction and has a complex impact on the Mn-Mn interactions. Theoretically calculated magnetic phase diagram of Ni₂Mn_1-xCu_xGa is in a good agreement with available experimental data. Calculated by the Monte Carlo method the isothermal magnetic entropy change Delta S_mag in a Ni₂Mn_{0.75 …}

Gene Expression Studies For The Analysis Of Domoic Acid Production In The Marine Diatom Pseudo-Nitzschia Multiseries, Katie R. Boissonneault, Brooks M. Henningsen, Stephen S. Bates, Deborah L. Robertson, Sean Milton, Jerry Pelletier, Deborah A. Hogan, David E. Housman

Biology

Background: Pseudo-nitzschia multiseries Hasle (Hasle) (Ps-n) is distinctive among the ecologically important marine diatoms because it produces the neurotoxin domoic acid. Although the biology of Ps-n has been investigated intensely, the characterization of the genes and biochemical pathways leading to domoic acid biosynthesis has been limited. To identify transcripts whose levels correlate with domoic acid production, we analyzed Ps-n under conditions of high and low domoic acid production by cDNA microarray technology and reverse-transcription quantitative PCR (RT-qPCR) methods. Our goals included identifying and validating robust reference genes for Ps-n RNA expression analysis under these conditions. Results: Through microarray analysis of …

Other Missouri Model: Systemic Juvenile Injustice In The Show-Me State, The, Mae C. Quinn

Missouri Law Review

Part II of this Article examines some of the most well-known claims about the Missouri Model of juvenile justice, clarifying that the positive press to date actually describes only one small component of the larger juvenile justice structure: Missouri’s system of residential correction for state-placed adjudicated youth. And while that system has much to admire and replicate, it also has room for improvement In Part III, this Article fills in what has been left out of most public and press stories about Missouri’s larger youth justice system. That is, despite mostly glowing media accounts, Missouri’s at-risk youth are poorly served …

Publications and Research

Tidal harmonic analysis simulations along with simulations spanning four specific historical time periods in 2003 and 2004 were conducted to test the performance of a northern Gulf of Mexico tidal model. A recently developed method for detecting inundated areas based on integrated remotely sensed data (i.e., Radarsat-1, aerial imagery, LiDAR, Landsat 7 ETM+) was applied to assess the performance of the tidal model. The analysis demonstrates the applicability of the method and its agreement with traditional performance assessment techniques such as harmonic resynthesis and water level time series analysis. Based on the flooded/non-flooded coastal areas estimated by the integrated remotely …

Executive Summary: Randomized Comparison Of Two Internet-Supported Methods Of Natural Family Planning, Richard J. Fehring, Mary Schneider

Randomized Comparison of Two Internet-Supported Methods of Natural Family Planning

Only 0.2% of US women use modern methods of natural family planning, i.e., the basal body temperature and the cervical mucus methods of natural family planning (NFP). The reason that such few women use NFP methods is because they are often ineffective, they are difficult to use, there is lack of access to properly trained NFP teachers, a lack of motivation to use a behavioral method, and health professionals are reluctant to prescribe NFP methods. One way to potentially increase the use of NFP methods is to provide easy access to an effective but simplified NFP method that uses a …

Influence Of Motivation On The Efficacy Of Natural Family Planning, Richard J. Fehring, Mary Schneider, Mary Lee Barron, Jessica E. Pruszynski

Randomized Comparison of Two Internet-Supported Methods of Natural Family Planning

Purpose: Mutual motivation is recognized as essential for effective behavioral methods of family planning. Few studies have studied this factor in family planning efficacy. The purpose of this study was to determine the influence of mutual motivation on unintended pregnancy rates of couples who used natural family planning (NFP) methods to avoid pregnancy.

Study Design and Methods: Using an online taught NFP method, 358women and ( their male partners) indicated “how much” and “how hard” they wished to avoid pregnancy on a scale of 0-10 before each menstrual cycle charted over 12 month of use. This motivation scale is used …

How To Enable Asian Teachers To Empower Students To Adopt Student-Centred Learning, Thanh Thi Hong Pham, Peter Renshaw

Australian Journal of Teacher Education

Asian teachers’ reluctance to empower students has been claimed to be an significant barrier preventing their students from practising student-centred learning. To promote student-centredness in Asian classrooms, this study aimed to develop strategies that could enable Asian teachers to delegate part of their authority to students. Twelve college teachers and six hundred and fifteen Vietnamese college students participated in this one-semester study. The results revealed that ‘artificial’ innovations such as forming group work and regularly questioning students in class did not mean empowering students in active learning. Students were only positioned and given opportunities to engage in proper student-centredness when …
