Background: Up-to-date dietary data are required to understand the diverse nutritional challenges of pregnant women living in low-middle income countries (LMIC). To that end, dietary data were collected from 1st trimester pregnant women in rural areas of Guatemala, India, Pakistan, and Democratic Republic of the Congo (DRC) participating in a maternal lipid-based nutrient supplement (LNS) Randomized Controlled Trial to examine dietary diversity (DD), usual group energy and nutrient intakes, and prevalence of inadequate dietary intakes.
Methods: Two 24-h dietary recalls were conducted in ~240 pregnant women/site (total n = 966) prior to 12-week gestation. Adequate DD was assessed, i.e., ≥5 …

Low Loading Gold Vapor Deposited Electrode For High Sensitivity As (Iii) Detection, Tybur Casuse

Civil Engineering ETDs

The objective of this thesis is to develop a method for detection of arsenite, As (III), using a thin film of gold (Au) vapor deposited onto carbon paper as an electrode. Currently, availability of drinking water arsenic (As) concentration information for rural communities is diminished due to high cost per sample analysis and limited access to analytical laboratories which can accurately determine concentrations near the 10 maximum contaminant level (MCL) set by the World Health Organization (WHO) and the US Environmental Protection Agency (EPA). The use of a minimal amount of gold aids in decreasing the cost of an electrode. …

Electron Transfer Activity Of Mitochondria Neet-Proteins, Yiming Wang

LSU Doctoral Dissertations

Mitochondrial NEET proteins are recently discovered iron-sulfur proteins that are localized within mitochondria. There are three NEET proteins: mitoNEET, a type II diabetes drug pioglitazone binding target, a mitoNEET related protein 1 (Miner1 or NAF-1), and a mitoNEET-related protein 2 (Miner2). While both mitoNEET and Miner1 are mitochondrial outer membrane proteins, Miner2 is a mitochondrial matrix protein. All three NEET proteins bind at least one [2Fe-2S] cluster via CDGSH (Cys-Asp-Gly-Ser-His) motif. In this work, we have investigated the electron transfer activity of mitoNEET, and found that the CDGSH-type [2Fe-2S] clusters of mitoNEET can be reduced by the reduced flavin mononucleotide …

Mathematics Experiences Of Students Who Are Blind Or Visually Impaired, Michaela Patricia Stone

LSU Doctoral Dissertations

Historically, researchers studying mathematics education for students with visual impairment (SVI) have faced several challenges. Quantitative researchers are limited by small sample sizes and the need to adapt traditional research instruments for accessibility by SVI. Qualitative research, most often conducted by sighted researchers and relying on the perspectives of sighted educators, suffers from the absence of the voices of the SVI being studied. Overwhelmingly, research on the mathematics education of SVI is explicitly grounded in deficit models of disability, falsely conflating the physical condition of impairment with the social act of disablement. Only in the past decade have critical disability …

Parts Of The Whole: Logical Categories Of Learning: Why Teaching Qr Is Hard, Dorothy Wallace

Numeracy

This column introduces the reader to an essay by anthropologist Gregory Bateson on the nature of learning. In that essay, he stratifies the learning process into categories based on what aspect of the student’s understanding is required to change in order to accomplish a given learning task. A discussion of the first three categories is followed here by examples from quantitative reasoning tasks and a further example from the ongoing discussion in the community of what numeracy entails. Bateson’s classification of learning into “logical categories” sheds light on what the goals of numeracy ask of both student and teacher, as …

Written in three parts, the book presents both the math and artistic design aspects of telling a story through figures. Wilke makes extensive use of examples, labels them good, bad, …

Teaching Demographic Ignorance With The Correcting Misperceptions Exercise: A Replication And Extension Of Previous Research, Daniel Herda

Numeracy

Existing research from the social sciences indicates that misperceptions about immigrants are pervasive in American society and present consequences for intergroup relations. The classroom may be an arena in which to reduce this incorrectness. The current note provides a replication and extension of previous research on the effectiveness of the Correcting Misperceptions Exercise (CME) ─ an in-class demographic guessing game in which students provide their perceptions of some demographic reality and compare it to an objective data source. This analysis builds upon earlier work by 1) considering immigrants as a new demographic category of focus; 2) simultaneously analyzing cardinal misperceptions …

Alignment Between Learning Objectives And Assessments In A Quantitative Literacy Course, Younggon Bae, Samuel L. Tunstall, Kathryn S. Knowles, Rebecca L. Matz

Numeracy

In this analysis, we examine how course assessment items were aligned with learning objectives in a quantitative literacy course at Michigan State University. The alignment analysis consisted of mapping assessment items to a list of operationalized learning objectives from the course. Our analysis shows how often the learning objectives are represented in assessment items, how often they are paired with other learning objectives, and how influential they are in contributing to a student’s course grade. In addition, through comparisons across four assessment types (e.g., exams and homework), we show how each learning objective was assessed differently within each assessment type. …

How Do We Change Statistical And Critical Thinking Attitudes In Young People?, Rhys C. Jones

Numeracy

A quasi-experimental design was used to measure the impacts on student attitudes in statistics, mathematics and critical thinking (16-18 years of age) on a group of students who received a 21-week-long contextualised statistics course (called the Pilot Scheme in Social Analytics), in South Wales. This paper will discuss the development and delivery stages of the course as well as the student recruitment strategies employed. This paper will also discuss the changes in attitudes observed after the course had finished. Results suggest the course did lead to changes in the students’ attitudes becoming more positive with respect to statistics, mathematics, and …

Using Meta-Analysis To Assess Affective Outcomes In A Multi-Course Qr Module Intervention, James Friedrich, Kelley D. Strawn

Numeracy

When quantitative reasoning(QR) interventions share a common hypothesis or goal, a promising approach for evaluation involves integrating separate analyses through the use of meta-analysis. This paper reports an assessment of a module-based QR intervention distributed across 20 courses at a single institution. Topics and participating courses were diverse, including arts & humanities, quantitative behavioral sciences, and natural sciences & mathematics groupings, but all addressed the shared affective goals of reducing student QR self-doubt and increasing appreciation for QR value and utility. With a local framework to guide module development, we assess these outcomes using reliable self-report measures in a pre-post …

Crossing The Final Frontier: Exploring The Numeracy Demands Of Texts Read In English Language Arts, Ellen C. Agnello, Kevin M. Agnello

Numeracy

Incited by the National Assessment of Educational Progress’ 2009 Reading Framework and the Common Core State Standards, recent shifts in national education goals have urged English language arts teachers to make curriculum adjustments. One such adjustment is to shift their focus from fiction, which has traditionally dominated the curriculum, to nonfiction. Doing so has the potential to increase students’ exposure to informational texts which often employ numeric modes to represent quantitative data, thus necessitating numeracy knowledge. This article presents a study of 60 nonfiction texts taught in secondary ELA classrooms. Through analysis of these texts, it addresses the questions: Which …

The aim of this research is to explore current maker spaces and maker communities related to fashion and textiles outside the formal education …

Assembling The Puzzle Of An Enigmatic Shark Tapeworm: A Comparative Genomic And Transcriptomic Approach, Kaitlin Gallagher

Doctoral Dissertations

The evolution of novelty among closely related taxa is a phenomenon that has occurred repeatedly within parasitic clades, however, the mechanisms that underlie the evolution of such innovations is not fully understood. This dissertation explores one example of this phenomenon that occurs in a monogeneric order of tapeworms, the Litobothriidea, that infect lamniform sharks. The most recently described member of this group, Litobothrium aenigmaticum, lacks all the characters typically demonstrated by members of this group, yet it robustly nests within the genus Litobothrium with the barcoding gene 28S rDNA (D1-D3). The aim of this dissertation was to investigate which …

The Nautics Materials Workshop: Teaching And Learning Interactive, Connected, And Smart Materials For Yacht Design., Stefano Parisi, Arianna Bionda, Andrea Ratti, Valentina Rognoli

Learn X Design Conference Series

Knowledge about materials is a key element in design education, considering not only their technical properties but also experiential and expressive-sensorial qualities of materials. To comply with this transition and with the emergence of novel materials, educators need to adapt or develop new formats, tools, and methods for teaching and learning materials in design curricula. This paper presents a tentative design methodology experimented and validated in an educational workshop names ‘NautICS Materials’ with the aim of (i) teaching ICS Materials in the absence of material samples, (ii) exploiting the potential of ICS Material in driving yacht design concepts; (iii) designing …

Forget To Clean Up When You're Done., Milena Radzikowska, Stan Ruecker, Jennifer Roberts-Smith

Learn X Design Conference Series

In most university settings the rooms are scheduled centrally in such a way that even moving tables and chair configurations can prove problematic. Because different faculty use the space for different purposes, common courtesy and institutional exigency both dictate that classrooms should be reset to neutral at the end of each session. However, from the perspective of design pedagogy this otherwise beneficial practice becomes problematic. For design students there is a strong benefit in the material culture of the design space being intrinsically modelled in the classroom. We therefore offer an alternative argument to the conventional deployment of classroom space, …

Contextual Fear Learning And Memory Differ Between Stress Coping Styles In Zebrafish, Matthew R. Baker, Ryan Y. Wong

Biology Faculty Publications

Animals frequently overcome stressors and the ability to learn and recall these salient experiences is essential to an individual’s survival. As part of an animal’s stress coping style, behavioral and physiological responses to stressors are often consistent across contexts and time. However, we are only beginning to understand how cognitive traits can be biased by different coping styles. Here we investigate learning and memory differences in zebrafish (Danio rerio) displaying proactive and reactive stress coping styles. We assessed learning rate and memory duration using an associative fear conditioning paradigm that trained zebrafish to associate a context with exposure to a …

Blockade Of Tgf-Β Signaling To Enhance The Antitumor Response Is Accompanied By Dysregulation Of The Functional Activity Of Cd4, Magdalena J Polanczyk, Edwin Walker, Daniel Haley, Bella S Guerrouahen, Emmanuel T Akporiaye

Articles, Abstracts, and Reports

BACKGROUND: The pleiotropic cytokine, transforming growth factor (TGF)-β, and CD4

METHODS: Using BALB/c, FoxP3eGFP and Rag

RESULTS: SM16 abrogates TGF-β-induced Treg generation in vitro but does not prevent global homeostatic expansion of CD4

CONCLUSIONS: These findings suggest that blockade of TGF-β signaling is a potentially useful strategy for blunting Treg function to enhance the anti-tumor response. Our data further suggest that the overall dampening of Treg function may involve the expansion of a quiescent Treg precursor population, which is CD4

A Dialectical Relational Analysis Of Tesol Quarterly 2006 Special Issue On Race: Discourse, Race, And White Supremacist Ideology, Ginger A. Looney

Language, Literacy, and Sociocultural Studies ETDs

Although the field of TESOL is not racially neutral this dialectical relational analysis examined (1) what discourses did the authors use to deploy race in the articles in the 2006 TESOL Quarterly Special Issue on Race (TQSIR)? and (2) how do these discourses work to either conform to, or resist white supremacist ideology? Analysis of the texts identified four key discourse: racialization, whiteness, emotional labor of racism, and sonic and optic negation of racism. These discourses were examined in the domains of scholarship, curriculum, teachers, and students. In 21 instances, these four discourses work to resist white supremacist ideology. …

Evolutionary computation has made its way in design curricula in the last two decades. However, questions remain on how evolutionary computation can be made more accessible to design students and its potential to transform design thinking and learning beyond optimisation. This paper examines how the formulation and implementation of evolutionary systems can contribute to students’ learning of historical and theoretical aspects of design. The paper reviews evolutionary computation in design and presents genetic algorithms (GAs) as a design tool. Opportunities are identified on how to teach design students to create and implement basic GAs. Strategies that can help design educators …

Self-Organization For Design Education: A Sustainable Flocking System, Nariman G. Lotfi

Learn X Design Conference Series

Scientists have discovered the efficiency and elegance of systems found in the behavior of natural groups, one of which is self-organization and flocking. Many researchers have studied and applied self-organization in business management but it is yet to be addressed in the design education field in Egypt. Design students are reliant on the teacher’s input which limits their independent decision-making and development. This study aims at introducing self-organization to groups of students in Egypt to enhance learning outcomes. A system was developed based on flocking to enable better team work experiences between design students. The system is based on using …
