The Effects Of Background, Classroom Assessment Competence, Self-Efficacy, And Self-Perceived Assessment Skills On Classroom Assessment Practices Of Teachers In India, Manognya Murukutla

UNLV Theses, Dissertations, Professional Papers, and Capstones

Teacher-conducted assessments are necessary to gather important information to facilitate student learning and academic success. Unfortunately, there is an inconsistency in teacher knowledge of assessment and assessment practices. While previous research identified a gap in teacher competence and teacher perceptions of their competence, and this affects classroom assessment practices that then impact student learning, the research is limited, outdated, and not grounded in any theoretical framework. This study addresses gaps in literature and establishes self-efficacy as a theoretical framework in which classroom assessment can be studied. Data were collected in India, and a path analysis and a Kruskal Wallis non-parametric …

The Parallel Security Apparatus: Examining The Cases Of Baathist Iraq, Syria, And Iran, Donald Utchel

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation examines the phenomena of the parallel security apparatus in the cases of Baathist Iraq, Syria, and Iran. Parallel security structures are often limited to books and articles published on secret police organizations in the broader security literature. Their research often focuses on one branch of the parallel security apparatus rather than examining all the parallel security institutions of that particular regime. This body of research attempts to bring further light to this particular phenomenon by examining all the parallel security institutions in a particular case and to connect and trace the various parallel security institutions to see if …

First-Personal Body Aesthetics As Affirmations Of Subjectivity, Madeline Martin-Seaver

Contemporary Aesthetics (Journal Archive)

This paper redirects some of the philosophical discussion of sexual objectification. Rather than contributing further to debates over what constitutes objectification and whether it is harmful, I argue that aesthetic experience is a useful tool for resisting objectification. Attending to our embodied experiences provides immediate evidence that we are subjects; aesthetically attending to that evidence is a way of valuing it. I consider the human body as an aesthetic site, then as an ethico-aesthetic site, and finally as a site of resistance. In addition to deepening accounts of body aesthetic experience, this paper helps frame human bodies as integral to …

A Noncanonical Function Of The Telomerase Rna Component In Human Embryonic Stem Cells, Kirsten Ann Brenner

Arts & Sciences Graduate Student Theses and Dissertations

Telomeres are stretches of TTAGGG nucleotide repeats located at the ends of linear chromosomes that shorten with progressive cell division and prevent genomic instability at the cost of limiting a cell’s capacity to proliferate. This limitation can be overcome by telomerase, a ribonucleoprotein complex that elongates telomeres via reverse-transcription of the template telomerase RNA component (TERC). Recent studies have reported potential functions of TERC outside of its role in telomere maintenance. These noncanonical functions of TERC are however poorly defined, and the molecular mechanisms and biological relevance behind such functions remain elusive. Here, we generated conditional TERC knock-out human embryonic …

Activation And Regulation Of The Alkbh3-Ascc Alkylation Repair Pathway, Josh Brickner

Arts & Sciences Graduate Student Theses and Dissertations

DNA repair is essential to prevent the cytotoxic or mutagenic effects of various types of DNA lesions. These lesions are sensed by distinct pathways to recruit repair factors specific to type of damage. In particular, the ALKBH family of proteins recognizes and repairs specific alkylated lesions, including 1-methyladenine (m1A) and 3-methylcytosine (m3C). A major outstanding question in the field is how the AlkB homologue ALKBH3 and its associated protein partners are recruited to sites of alkylation damage and how this repair activity is regulated. Understanding the upstream signaling events that mediate recognition and repair of DNA alkylation damage is particularly …

Young Children’S Knowledge About The Role Of Print In Reading, Molly Farry-Thorn

Arts & Sciences Graduate Student Theses and Dissertations

Children begin to learn about the print in books and the role it plays in reading well before the onset of formal literacy instruction. Young children’s knowledge about precisely what readers are reading when they read books and who is able to read books has been studied primarily through interviews, but conclusions from this research are limited by methodological concerns. Three experiments examined whether pre-readers understand what part of a book is read and whether they distinguish between the skill of reading and the activity of reading. Although pre-readers were typically able to locate the print in a book, they …

Transcriptional Regulation Of Adipose Tissue Development By Pexrap And Med19, John Dean

Arts & Sciences Graduate Student Theses and Dissertations

Targeting adipose tissue function to decrease adiposity and improve insulin sensitivity could treat obesity and diabetes. How the nuclear receptor PPARγ regulates the development of two functionally distinct types of adipose tissue, brown and white fat (BAT and WAT), as well as the browning of white fat, remains unclear. Our previous studies suggest that PexRAP, a peroxisomal lipid synthetic enzyme, regulates PPARγ signaling and white adipogenesis.Here, we show that PexRAP is an inhibitor of brown adipocyte gene expression. PexRAP inactivation promoted adipocyte browning, increased energy expenditure, and decreased adiposity. Identification of PexRAP-interacting proteins suggests that PexRAP function extends beyond its …

Devising A Scalable Synthesis To Probe The G-Protein Cell Receptor Signaling Pathway, Matthew Robert Medcalf

Arts & Sciences Graduate Student Theses and Dissertations

The G-protein coupled cell receptor signaling pathway is amongst the largest and most diverse class of cell-surface receptors in the body. Nearly 800 different genes encode for these cell membrane receptors which are responsible for mediating a variety of hormones, neurotransmitters, and sensory stimuli through the activation of intracellular G proteins. To date, roughly 34% of pharmaceuticals on the market target GPCR’s, but despite this fact, there are still many difficulties associated with targeting this family of receptors. The vast number of GPCR’s, disease states resulting from a dysregulation of multiple GPCR signaling pathways, and difficulties crystalizing and purifying the …

Crip Time In Fin-De-Siècle Spain: Disability, Degeneration, And Eugenics, Erika Rodriguez

Arts & Sciences Graduate Student Theses and Dissertations

A period of intense nation-building, the late nineteenth century was marked by the search for medical and legal solutions to the increasing number of bodies that did not align with culturally constructed expectations of productivity and reproduction in Spanish modernity. Authors of this time used representations of disability to engage in urgent political questions about population control and the rights of individuals in the face of increasing medical intervention. In carrying out this analysis, I raise the question of how representations of disability created a space to reconfigure the social values that determined what lives matter. Focusing on canonical realist …

Generation And Utilization Of Diverse Memory B Cells After Flavivirus Challenges, Rachel Wong

Arts & Sciences Graduate Student Theses and Dissertations

Over the course of an effective immune response to an infection, two distinct B cell populations are generated to provide protection against reinfection, long-lived plasma cells (LLPCs) and memory B cells (MBCs). LLPCs and MBCs originate from germinal center (GC) B cells that have undergone B cell receptor (BCR) affinity maturation through iterative rounds of somatic hypermutation, proliferation, and selection. Thus, LLPCs and MBCs can bind to their antigen with higher affinity than their naïve B cell precursors. LLPCs constitutively secrete antibodies and can provide sterilizing immunity that pre-exists subsequent infections. MBCs, on the other hand, are quiescent and provide …

Globally it is estimated that there are 285 million persons living with some sort of vision related difficulties. In Ghana, about 737,743 Ghanaians living with disabilities (Ghana Statistical Service, 2012). The United Nations and other international organizations have always emphasized the importance making education and educational services accessible to all. In recent times, there have been advocates for inclusive education where children with disabilities have been educated together with ‘able bodied’ colleagues. The purpose of this study was to examine library infrastructure for the visually impaired in the public universities in Ghana. The study adopted both qualitative and quantitative …

Georgic Rhetoric, Virtue And The Commercialization Of Agriculture In Pennsylvania From 1785 To 1870, Naomi Ulmer

Masters Theses, 2010-2019

This research examines how farmers in Pennsylvania between 1785 and 1870 were persuaded by georgic agrarianism to take social, economic and even moral risks to abandon a semi-subsistence mode of production in favor of commercial production. The georgic rhetoric is derived from Virgil’s poem “The Georgics.” It discusses agriculture and man’s labor in nature. Virgil discusses the relationship between man, nature and his ability, or inability, to control nature to ensure his own survival. Beginning in the late 18^th century, supporters of improved agriculture, mostly wealthy and upper-class gentlemen, tried to persuade common yeomen farmers to produce for the …

Computer Self-Efficacy, Digital Learners, And Completion Rates In The California Community College System, John R. Otte

CUP Ed.D. Dissertations

The importance of online learning in higher education has increased considerably over the last two decades. As a result, online learning has become an important area of research. The purpose of the study was to examine if higher levels of computer self-efficacy (CSE) contributed to online course completion among online California community college students. Guided by Bandura’s (1977) work on self-efficacy and the work of Compeau and Higgins (1995) and Howard (2014) on computer self-efficacy, this study revealed that there is no relationship between high levels of CSE and successful completion of the course. A judgement sample was used to …

Mathematics & Statistics ETDs

This project is concerned with investigating the question, "Do our applied linear algebra courses (at the University of New Mexico) adequately prepare STEM students for future work in their respective fields?" In order to explore this, surveys were issued to three groups (sections) of students (among two different instructors) at the conclusion of their applied linear algebra course, as well as STEM professors/instructors from a variety of STEM fields. Students were surveyed regarding their perceived mastery of given topics/ideas from the course and professors/instructors were surveyed about the level of mastery they felt was necessary (referred to as ``desired mastery") …

How To Promote Education For Sustainable Development? Vision Of The Educational Situation And Its Contribution To Sustainable Development., Khalid Aada

Writing and Language Studies Faculty Publications

During the last decade, the importance of leaving a rational paradigm, debtor of functionalist and utilitarian models, towards another more congruent with the preservation of natural resources, and therefore of life, has been widely discussed. In the same way, different voices have been raised, pointing out the urgency of inserting these precepts into the educational field, hoping to achieve the true cultural transformation that is needed to consolidate the change. Multiple International Entities promote sustainability in Education as an initiative that should be ambitious, complex and reforming character, given the global scope of the social, economic and environmental situation affecting …

Non-Trivial Off-Path Network Measurements Without Shared Side-Channel Resource Exhaustion, Geoffrey I. Alexander

Computer Science ETDs

Most traditional network measurement scans and attacks are carried out through the use of direct, on-path network packet transmission. This requires that a machine be on-path (i.e, involved in the packet transmission process) and as a result have direct access to the data packets being transmitted. This limits network scans and attacks to situations where access can be gained to an on-path machine. If, for example, a researcher wanted to measure the round trip time between two machines they did not have access to, traditional scans would be of little help as they require access to an on-path machine to …

Another Shot At Rectifying The District Of Columbia V. Heller Ambiguities: The Constitutional Right To Arms, The Nonconstitutional Right To Arms, And The Commerce Clause, Noah Gaarder-Feingold

San Diego Law Review

In an article for The New Yorker titled Active Shooter, David Sedaris quipped that, in preparing for the potential that a psychopath might break into his home, he would just as soon have a back door as a gun. Sedaris wrote the article after visiting a shooting range in North Carolina. Before, during, and after the writing of the article, Sedaris lived in the United Kingdom and noted that in the United Kingdom, it is nearly impossible to acquire a handgun let alone fire a handgun for sport.

Conversely, in the United States, a citizen has a right to a …

Integrated Design Approach For Coronary Stents Using Flexinol Shape Memory Alloy, Matthew Lucci

Mechanical Engineering Theses

This research seeks to develop and verify a model for control of the shape memory alloy (SMA) Flexinol and apply such findings to practical application of the material as a platform for bare metal stenting technologies. Utilizing experimental data and material properties, a mathematical model of the thermoelectric contraction behavior of Flexinol wire samples was developed. This model accounted for variable resistance due to the shape memory effect of the Flexinol wire as it experiences a crystalline phase change. It also accounted for the change in the cross-sectional area of the wire as the wire experienced thermal expansion and contraction. …

Objectification Of Women In Rap Music Videos, Jamie O. Broadnax

Research Papers

Misogyny in the hip-hop culture has played a major role in the representation of women in society, and their glorification as sex objects in music videos is becoming popular and inevitable. Women are often objectified in Hip Hop music and this research project presents how women are being used as targets for objectification in music videos and the violent treatment by men in these videos are analyzed. Author Murali (2010) mentions that black womanhood has become more closely connected to postmodern identity and resistance. The post hip-hop era, feminists and media critics brought up the idea of who controls the …

Molecular Dynamics Studies Of Thin-Film Evaporation: The Effect Of Graphene-Coated Silicon On Water Evaporation Behavior, Rui Zhou

McKelvey School of Engineering Graduate Student Theses & Dissertations

Conventional single-phase air or liquid cooling methods are insufficient to dissipate the high heat flux of next-generation electronic systems. Thin-film evaporation is one of the most promising solutions, because it takes advantage of the large amount of latent heat in the phase change process. It is important to understand the relationship between interfacial thermal resistance, surface wettability, and thin-film evaporation behavior. In this study, non-equilibrium molecular dynamics simulations are used to study mass and heat transfer in thin-film evaporation of water on a silicon substrate, and equilibrium molecular dynamics simulations are used to study the surface wettability by measuring contact …

Pupil-Athletes’ Learning Dispositions And Their Potential Effects In School Sports-Situated Talent Development Programs, Anna Renström, Cecilia Stenling

Journal of Athlete Development and Experience

There is a worldwide increase in efforts to support talents’ development towards elite athletes. The focus of the study was the learning processes among athletes that facilitate this development. Drawing on the learning dispositions concept (Carr & Claxton, 2002), the aim was to create knowledge on the prevalence and possible consequences of variability in learning patterns among pupils enrolled in Nationell Idrottsutbildning Fotboll (NIUF)—a highly selective soccer talent development programme within upper secondary schools in Sweden. In-depth semi-structured interviews were carried out with a total of 13 pupils in their first or second year of NIUF. The data analysis benefited …

Are Athletes Addicted To Their Identity? The Development And Validation Of The Athletic Identity Addiction (Aia) Scale, Matt R. Huml, Calvin Nite

Journal of Athlete Development and Experience

The purpose of this study was to develop a reliable and valid instrument for assessing the extent to which athletic identity is related to the tenets of addiction. Specifically, it was investigated whether athletes experience a behavioral addiction regarding their participation and involvement in sport. A total of 576 athletes (118 student-athletes, 458 former student-athletes) were included within a two-phase study. The first phase focused on crafting and testing the instrument, while the second phase refining the instrument for validity and reliability. Results indicated a four-factor solution comprising the Athletic Identity Addiction (AIA) scale: (1) mood alteration, (2) withdrawal, (3) …

An Inclusive Economic Paradigm Shift, Jonathan Talbot

Capstone Collection

In this paper, the author begins with the question of how we can recognize whether or not we are in an opportune time to re-evaluate our current economic system. Through a literature review the canvas is set for the surveys of 63 people from across the United States about the way they feel about the economic system within which we currently find ourselves. Through the survey, he establishes that people who report having had a harder time during the “economic recovery” of the Great Recession were more likely to act in the hopes of bettering their community than those who …

Understanding The Role Of Idh Mutation In Chondrosarcoma, Luyuan Li

Open Access Dissertations

Chondrosarcomas constitute a heterogeneous group of malignant bone tumors that produce hyaline cartilaginous matrix. Chondrosarcomas are generally resistant to conventional chemotherapy and radiotherapy, leaving surgery as the only curative treatment option for most localized tumors. In the absence of effective systemic therapy, metastatic disease is nearly uniformly fatal. Therefore, better therapy for patients with unresectable or metastatic disease is urgently needed. Mutations in isocitrate dehydrogenase 1/2 (IDH1/2) enzymes were recently described in several malignancies including conventional and dedifferentiated chondrosarcomas. These mutations represent a novel genetic abnormality in chondrosarcoma, indicating a potential role for aberrant IDH function in the pathogenesis of …

A Role For The Hypoxia-Inducible Factor 1 Alpha In Murine Gammaherpesvirus 68 (Mhv68) Lytic Replication And Reactivation From Latency, Darlah Michelle López-Rodríguez

Open Access Dissertations

The hypoxia inducible factor 1 alpha (HIF1α) protein and the hypoxic microenvironment are critical for infection and pathogenesis by the oncogenic gammaherpesviruses (γHV) such as Kaposi' Sarcoma-associated Herpes Virus (KSHV) and Epstein-Barr virus (EBV). However, understanding the role of HIF1α during the virus life cycle and its biological relevance in the context of host pathogenesis has been challenging due to the lack of animal models for human γ HV. To study the role of HIF1α we employed the murine gammaherpesvirus 68 (MHV68), a rodent pathogen that readily infects laboratory mice. We show that MHV68 infection induces HIF1α protein and HIF1α-responsive …
