Development Of A Concept Exploration Based Teaching Methodology For Undergraduate Chemistry Education, Nicole D. Gray

All ETDs from UAB

Science in general has traditionally been noted as a difficult subject because of its specialized language, mathematical and abstract concepts, and the amount of content to be learned in a semester. In particular, students are believed to base their attitudes towards science-related disciplines on their perceived abilities in understanding or succeeding in a course. Other factors may also contribute to this lack of interest, such as students' metacognitive skills. Concept mapping and computer-aided tools may be used to assist students in building hierarchical knowledge bases that allow them to visually represent connections between concepts. Therefore, the purpose of this study …

Regulation Of Skeletal Muscle Plasticity Using Engineered Configurations Of The Transcription Factors Myod And E12, Vladimir Grubisic

All ETDs from UAB

Skeletal muscle fibers, although terminally differentiated, can change their features, such as contraction speed and endurance, and throughout adult life in response to variety of stimuli, like exercise. This process is called plasticity and is mainly regulated by the type of nerve activity. Over the past several decades, research has shown that the properties of myofibers are also determined during muscle development. Ultimately, the change in phenotype requires a change in gene expression which is, in turn, regulated by transcription factors (TFs). Basic helix-loop-helix (bHLH) TFs regulate myogenesis and the central role belongs to the myogenic differentiation 1 (MyoD), often …

Password Protected Visual Cryptography Via Cellular Automaton Rule 30, Roman V. Yampolskiy, Jovan D. Rebolledo-Mendez, Musa M. Hindi

Faculty and Staff Scholarship

Visual cryptography depends on two shares. The initial configuration, extra security bits and the number of the rule for the CA along with the number of computed steps serve as a password for a visually encrypted image. The second share could contain a predefined pattern; the developed algorithm uses a snapshot of a CA after a certain number of steps to generate the predefined share. Only one of these shares has to be random. The developed encryption system is a hybrid between visual and classical cryptographic approaches. It requires less storage space compared to a standalone visual encryption system and …

A Study On The Elementary School Teachers’ Awareness Of Students’ Alternative Conceptions About Change Of States And Dissolution, Chanho Yang, Taehee Noh, Lawrence C. Scharmann, Sukjin Kang

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Knowledge about students’ conceptions is one of the requisite components of pedagogical content knowledge. A keen awareness of students’ alternative conceptions provides teachers with information about prospective difficulties students may incur as they make attempts to learn more accurate scientific representations of critical concepts. In this study, we investigated elementary school teachers’ understanding of their students’ alternative conceptions about change of states and dissolution. The subjects were 152 elementary school teachers and 529 sixth graders in Korea. A conceptions test and the test of the understanding about students’ conceptions were administered in order to examine students’ alternative conceptions and the …

Narrative Understandings Of A School Policy: Intersecting Student, Teacher, Parent And Administrator Perspectives, Elaine Chan, Vicki Ross

Department of Teaching, Learning, and Teacher Education: Faculty Publications

In this article, we examine one school’s experience with policy, as a means of shedding light on the intersection of factors contributing to challenges of implementing policies to support the academic achievement and social adaptation of immigrant and minority students in their school context. We begin with the presentation of a ‘big fight’ between two students of different ethnic and racial backgrounds, and consider multiple perspectives of how the disagreement was addressed by teachers and administrators, to offer insight into how issues of race and policy might have been understood by members of the school community. We use a narrative …

“Women Made It A Home”: Representations Of Women In Social Studies, Mardi Schmeichel

Department of Teaching, Learning, and Teacher Education: Faculty Publications

This article explores recently published P–12 social studies lesson plans that include women to examine how attending to women is “getting done” in the field and how the lessons represent women and women’s experiences. Using discourse analysis methodologies, the author demonstrates that women have been included as topics in ways that do not work toward disrupting problematic discourses about gender norms. Through their avoidance of issues of power and patriarchy, most of the lessons fall short of addressing gender inequity—in the past or the present—in a significant way. More critical attention to women and gender in lessons, as well as …

(Dis)Functions: Marxist Theories Of Architecture And The Avant-Garde, Michael Chapman

Contemporary Aesthetics (Journal Archive)

This paper investigates the relationship between architecture and theories of the avant-garde in the critical projects of the 1970s, with a focus on the theories of Peter Bürger and Manfredo Tafuri. Both Tafuri and Bürger were writing from within the context of a radicalized Marxism and were fueled by an intellectual pessimism towards the totalizing systems of cultural production that questioned the role of resistance in aesthetics and the inability of the historical avant-gardes to engage within the political and economic fields of contemporary society. While there is a common ancestry to these two approaches, and mutual acceptance of the …

Politics And Aesthetics: Partitions And Partioning In Contemporary Art, Jonathan Owen Clark, Joao Lima Duque

Contemporary Aesthetics (Journal Archive)

Jacques Rancière defined the “distribution of the sensible” as the effect of a type of aesthetico-political decision-making that creates a partitioning of the realm of the perceivable in relation to both art and society. The artworld itself constructs its own particular types of curatorial partitioning: between “art” and “non-art,” between “dominant, residual, and emergent,” and between “mainstream” and “periphery.” This essay examines certain “boundary effects” that develop as a result of the act of the partitioning itself and closely examines what arguably are two new categories in contemporary art: “crossover” and “interventionist.” Both categories have a certain relationship to a …

Sexism, Statements, And Audits, Eric Schniter, Timothy W. Shields

ESI Working Papers

Gender stereotypes and gender-discriminant behaviors have been shown to have strong and undesirable organizational, managerial, and economic effects. We examine the relationship between sexism and accounting practices, and the effect of contextual feedback using laboratory experiments. Sexist stereotypes and contextual feedback may affect the likelihood of financial misstatements and audits when auditors and issuers are of known gender. To investigate these aspects of sexism at zero acquaintance and after contextual feedback, we presented males and females with incentivized belief elicitation tasks about anticipated interaction behaviors and then a series of strategic-communication game decisions in same, other, and unknown gender interactions. …

Divided Loyalists Or Conditional Cooperators? Creating Consensus About Cooperation In Multiple Simultaneous Social Dilemmas, Matthew W. Mccarter, Anya C. Samak, Roman M. Sheremeta

ESI Working Papers

The current social dilemma literature lacks theoretical consensus regarding how individuals behave when facing multiple simultaneous social dilemmas. The divided-loyalty hypothesis, from organizational theory, predicts that cooperation will decline as individuals experience multiple social dilemmas with different compared to the same group members. The conditional-cooperation hypothesis, from behavioral economics, predicts that cooperation will increase as individuals experience multiple social dilemmas with different compared to the same group members. We employ a laboratory experiment to create consensus between these literatures and find support for the conditional-cooperation hypothesis. The positive effect of interacting with different group members comes from participants having an …

The New Hampshire Effect: Behavior In Sequential And Simultaneous Election Contests, Zeynep B. Irfanoglu, Shakun D. Mago, Roman M. Sheremeta

ESI Working Papers

This experimental study compares sequential and simultaneous election contests. Consistent with the theory, we find evidence of the “New Hampshire effect” in the sequential contests, i.e., the winner of the first electoral battle wins the overall contest with much higher probability than the loser of the first battle. However, contrary to the theory, sequential contests generate higher expenditure than the simultaneous contests. This is mainly because in the sequential contests losers of the first battle do not decrease their expenditure in the second battle while winners of the first battle increase (instead of decreasing) their expenditure in the second battle. …

Self Discrimination: A Field Experiment On Obesity, Antonios Proestakis, Pablo Brañas-Garza, Praveen Kujal

ESI Working Papers

Empirical evidence suggests that physical characteristics such as obesity can result in a salary gap in the work place. It is, however, not clear how much of this (gap) is due to factors emanating from the demand or supply side of the market. In this paper we use a eld experiment to study whether a part of this wage gap can be attributed to personality traits of individuals on the supply side. Monitors randomly select individuals to respond to a questionnaire. Individuals can make money requests for completing the questionnaire. In the questionnaire they also self-report several personality chracteristics. We …

When Identifying Contributors Is Costly: An Experiment On Public Goods, Anya Savikhin Samek, Roman M. Sheremeta

ESI Working Papers

Studies show that identifying contributors significantly increases contributions to public goods. In practice, however, viewing identifiable information is costly, which may discourage people from accessing such information. To address this question, we design a public goods experiment in which participants can pay a fee to view information about identities and corresponding contributions of their group members. We then compare this to a treatment in which there is no identifiable information, and a treatment in which all contributors are freely identified. Our main findings are that: (1) contributions in the treatment with costly information are as high as those in the …

An Evaluation Of The Penn Resiliency Program For Disruptive Preadolescents In An Elementary School Setting, Mildred Howard

Doctoral Dissertations and Projects

The primary purpose of this study was to evaluate the effectiveness of the Penn Resiliency Program in decreasing disruptive behavior, modifying negative automatic thoughts and improving academic achievement. Forty-eight students from two Title I schools in Georgia participated in this study. The Behavior Assessment Scale for Children, Second Edition, Progress Monitor, The Children's Automatic Thoughts Scale and report card grades were used to evaluate program effectiveness. Research results suggest the program effectively reduced negative automatic thoughts and improved academic performance.

Characterization Of The Disulfide In The Ectodomain Of Anthrax Toxin Receptor 2, Pedro Raymundo Jacquez

Open Access Theses & Dissertations

Anthrax toxin receptors act as molecular clamps or switches that control anthrax toxin entry, pH-dependent pore formation, and translocation of enzymatic moieties across the endosomal membranes. The ectodomain of anthrax toxin receptor 2 (ANTXR2) is composed of a von Willebrand factor A (VWA) domain that binds to anthrax toxin protective antigen (PA) and a newly defined immunoglobulin-like (Ig) domain, in which the disulfide bonds are required for PA pore formation and for the folding of ANTXR2. While the VWA domain has been well characterized, the structure and function of the whole ectodomain (VWA-Ig) are poorly defined, this is mainly due …

Digital Biliteracy: Digital Technologies As Homes For Arab Immigrant Children's Biliteracy Development, Laila Al-Salmi

Open Access Theses & Dissertations

The revolution of digital technologies and children's increasing access to them is

impacting the literacy development of children around the world. However, few studies have investigated the relationship between digital technologies and immigrant children's biliteracy development. The purpose of this study was to understand the digital literacy practices of Arab pre-kindergarten children and how these shape biliteracy development in Arabic and English. Tomake sense of the emergent biliteracy of these young participants, the study proposed Digital Biliteracy, a theoretical framework that draws on elements of New Literacy Studies, MultimodalLiteracies, Digital Literacies and Situated Learning Theory.

The study employed a qualitative …

Biochemical Characterization Of Four Distinct Proteins, Gustavo A. Avila

Open Access Theses & Dissertations

Proteins are ubiquitous in all living organisms, executing the majority of cellular functions in distinct ways. Understanding a protein's role necessitates investigating its structure and function, which are closely related. My research couples these two aspects by delving into the biochemical and structural characterization of proteins in four distinct systems, all playing central roles in numerous significant disease progressions. These four original research endeavors were all targeted for structural studies with a unifying relationship to establish our new structural biochemistry lab. These four systems are: (1) Gam1, an early adenovirus protein globally inhibiting host SUMOylation; (2) Anthrax toxin complexed with …

Psychographic Characteristics And Health Behaviors In Young Adults, Jose Alonso Cabriales

Open Access Theses & Dissertations

Tobacco use remains the leading cause of preventable death in the U.S. Non trivial smoking rates are observed among young adults and Hispanics, particularly as light and intermittent smoking is on the rise. Additionally, the assessment of other health behaviors including alcohol use, physical activity, and dietary practices seems warranted in young adults. The primary aim of this study was to identify clusters of individuals based on psychographics (e.g., lifestyle, preferences, personality characteristics), and their relation to tobacco use within a primarily Hispanic young adult border sample. Secondary aims were the assessment of group differences with respect to alcohol use, …

Through The Eyes Of The Dead Others, Isaac Aaron Ceniceros

Open Access Theses & Dissertations

I use Edith Wyschogrod's figure of the heterological historian to argue that we have a responsibility to learn from the "dead others" of the past in order to better apply in practical ways the lessons we learn from history. I draw on an interpretation of Nietzsche's view on historiography, to examine the claims of Hegel's dialectic, namely, that the Ideal Absolute for which Spirit pines, is actually achievable, particularly through the advent of the Internet. Beginning with a relatively well-known interpretation of Hegel's philosophy of history, Fukuyama's, I show how Hegel's dialectic takes shape in Fukuyama's interpretation as a negative …

Effects Of Electrical Pulse Stimulation On In Vitro Measurement Of Mitochondrial Content And Lipid In Human Myotubes, Daniel Alberto Conde

Open Access Theses & Dissertations

It has been previously shown that human myotubes retain certain in vivo characteristics of the donors. Furthermore, we have shown that Electrical pulse stimulation (EPS), an in vitro exercise mimetic, increases mitochondrial and lipid content in cultured human myotubes after 24 hr. of stimulation. Purpose: We aimed to examine the EPS induced adaptations to lipid, mitochondrial, and Glucose transporter 4 (GLUT4) content using human myotubes. Methods: EPS was applied to myotubes for 60 min (bipolar pulses of 100 Hz, 30V, every 5 seconds), 24 hr. or 48 hr. (single bipolar pulses of 1 Hz for 2 ms; 30V) and were …

Spingolipid Metabolism In A Reptillian Protozoan, Entamoeba Invadens, Duran Dogan Debons

Open Access Theses & Dissertations

Entamoeba invadens (hereinafter E. invadens) is an anaerobic parasitic protozoan that can be found in water and soil. Although the host organisms for this parasite are snakes, lizards, and other reptile species, the parasite is morphologically identical to Entamoeba histolytica, a causative agent of human amebiasis. Entamoeba inavdens exists in two morphological forms--(1) a replicative trophozoite, and (2) a relatively dormant cyst. While the transformation of cyst to trophozoites (called "excystation") takes place in the stomach, the differentiation of trophozoites to cyst (known as "encystation"), occurs in the small intestine. Unlike the cyst, a trophozoite is unable to survive …

Global Sphingolipid Profile Of Giardia Lamblia During Stage Differentiation: The Influence Of Sphingomyelin Abundance On Viable Cyst Production, Trevor Thomas Duarte

Open Access Theses & Dissertations

Giardia lamblia is a protozoan parasite and a major cause of the waterborne-illness, giardiasis, worldwide. Giardiasis is endemic in developing countries and is a leading cause of non-viral- and non-bacterial-associated intestinal disorders. Acute symptoms of giardiasis include diarrhea, cramps, and malabsorption. The disease is often self-limiting, although the infection can result in long-term disorders such as chronic fatigue, stunted cognitive skills, and failure to thrive even after the parasite has been cleared.

This parasite exists in two morphologic forms--infective trophozoites and transmissible, water-resistant cyst, which is passed by the fecal-oral route and is likely to be spread by contaminated drinking …
