Low-Dimensional Signatures Of Neuronal Activity Associated With Long-Term Operant Conditioning In Aplysia, Sara Vanaki, Nicholas O Gonzalez, Curtis L Neveu, Yuto Momohara, Behnaam Aazhang, John H Byrne

Faculty, Staff and Student Publications

Operant conditioning is a form of learning in which a behavior is reinforced by reward. Operant conditioning has multiple temporal domains, ranging from short-term, lasting a few minutes, to long-term, persisting for at least 24 h. The extent to which short- and long-term operant conditioning memories rely on shared or separate neural mechanisms is poorly understood. Voltage-sensitive dye (VSD) imaging has been used previously to record the activity of a large number of neurons simultaneously in the buccal ganglion to measure changes in neuronal activity during short-term operant conditioning. We examined neuronal activity using VSD 24 h after operant conditioning …

Mapping Climatic And Environmental Determinants Of Parasitic Helminth Prevalence In Southeast Asia, Angelica Avisado

UNLV Theses, Dissertations, Professional Papers, and Capstones

Climate change is reshaping environmental conditions across Southeast Asia (SEA) through rising temperatures, altered precipitation patterns, and increased droughts. These changes alter transmission dynamics of neglected tropical diseases (NTDs) by shifting spatial distribution, increasing larval development rates, faster pathogen growth development, and increasing transmission rates. NTDs are a group of preventable and treatable infections that disproportionately affect more than 1 billion people globally, specifically in tropical and subtropical regions. A subgroup of NTDs, parasitic helminth infections (PHIs) - particularly schistosomiasis, soil-transmitted helminths, and lymphatic filariasis remains a public health concern in the Southeast Asian region. PHIs and their ecological responses …

Automated Spectrum Analysis And Radionuclide Identification For Robot-Based Gamma Probes, Kennedy Ochieng Mengoh Alila

UNLV Theses, Dissertations, Professional Papers, and Capstones

Gamma spectroscopy is a technique used for the detection and identification of nuclear materials. Gamma-ray emission by radio nuclides is detected using scintillation detectors or semiconductor detectors such as NaI and CZT. Robot-based gamma probes enable radiation measurements in large areas and hard-to-reach cluttered hazardous environments, which significantly reduces radiation risks to personnel. The robotic probes require automated on-board gamma spectrum analysis and capabilities with platforms (unmanned aerial vehicles and unmanned ground vehicle systems) which use Robot Operating System (ROS). The aim of this thesis was to develop a method of an automated spectral analysis and isotope identification for robot-based …

The Maroons: The First Black Nationalists Of The Americas, Marquise K. Camp

UNLV Theses, Dissertations, Professional Papers, and Capstones

Maroon communities are seldom discussed in academic discussions about Black nationalism. This suggests that the goals and achievements of the Maroons differed from those of Black nationalists, and that there are no significant historical links between the two. This project argues that Black nationalists and the Maroons are closely related, not only because of their shared roots in the African diaspora but also because they both sought independence and self-governance for Black people. The aims of Black nationalists like Marcus Garvey and Malcolm X closely resemble those of the Maroons. By examining the Maroons alongside Black nationalism, one can gain …

UNLV Theses, Dissertations, Professional Papers, and Capstones

This qualitative phenomenological study explored post-probationary principals’ perceptions of professional development, examining the relevance, adequacy, and impact of support provided after 4 years of their leadership. Although research and policy have emphasized the development of new principals, professional learning opportunities for those beyond probationary status remain inconsistent, generic, and misaligned with individual and contextual needs. Guided by adult learning theory, this study sought to understand how post-probationary principals evaluate current professional development, describe their desired opportunities, and determine their ongoing needs. Data were collected through semi-structured interviews with principals from multiple districts and analyzed using coding, memo writing, and mind …

A Phenomenological Study Of The Experiences Of Adolescents With Emotional Behavioral Disorders In High School, Melissa Lawson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Adolescents with emotional and behavioral disorders (EBD) face significant challenges in forming and maintaining peer relationships, yet their voices and lived experiences remain largely absent from the research literature. This phenomenological study explored how high school students with EBD perceive the impact of peer relationships on their academic, social, and emotional experiences at school. Using Moustakas's (1994) modification of the StevickColaizzi-Keen method, the researcher conducted in-depth semi-structured interviews with seven high school students (ages 15-18) who had received special education services under the EBD eligibility category for 5 to 10 years in a large, urban southwestern school district.

A Case Study Of The Implementation Of Nevada’S Program To Reduce Recidivism Of The State’S Female Prison Population, Lisa C. Levine

UNLV Theses, Dissertations, Professional Papers, and Capstones

Success in public administration is often defined by long-term goals that demonstrate how effective a program or policy is. These long-term goals can take years to measure leading to investment doubts, shifting stakeholder goals, and the sunsetting of programs. There is a need to better understand how short-term and intermediate outcomes of a program can be used to measure success and the role goal orientation of stakeholders play in the implementation. Prison education programming exemplifies this problem as reducing recidivism, a leading goal for these types of programs, take a lifetime to prove. This study examines a female prison education …

Geometric And Proximity Based Substrate Targeting By Cullin-Ring Ligases, Jerry Li

UNLV Theses, Dissertations, Professional Papers, and Capstones

Homeostasis, the process of maintaining stable biochemical and biophysical conditions, is a fundamental facet of cellular viability. Biochemical homeostasis is critical to support the biological functions that sustain living organisms. Protein ubiquitylation is one of the primary cellular pathways that regulate protein homeostasis and turnover. Ubiquitylation is initiated through the conjugation of a small globular protein known as ubiquitin, onto a given substrate. There exists a myriad of cellular fates that ubiquitylated proteins may undergo, but the most widely studied pathway is protein degradation, whereby a ubiquitylated protein substrate is shunted to a large macromolecular protease known as the proteasome, …

Preparing Aspiring School Administrators For Data-Informed Decision-Making, Brandi March

UNLV Theses, Dissertations, Professional Papers, and Capstones

School leaders significantly impact student outcomes based on their ability to influence school culture, climate, and student engagement. They are essential for driving school achievement and instructional improvement. As educational policies increasingly emphasize data usage, leaders must utilize various data sources in a problem-solving process known as datainformed decision-making (DIDM) to effectively guide their school improvement plans. Using DIDM effectively can enhance instruction and student achievement when school administrators and teachers have access to quality training that builds a strong foundation in data literacy skills. It is critical for administrators to provide high-quality professional development for teachers on DIDM to …

UNLV Theses, Dissertations, Professional Papers, and Capstones

The present study experimentally manipulated the demographic characteristics of the subjects of moral dilemmas such that they were 20%, 40%, 60%, and 80% demographically similar to participants. Participants rated each of these individuals on a novel measure of perceived inherent value, the Perceived Inherent Value Scale (PIVS) and responded to a series of moral dilemmas using the Consequences, Norms, and preference for Inaction (CNI) model of moral decision making where the subjects of the moral dilemmas were the 20%, 40%, 60%, and 80% similar individuals. Participants rated individuals who were more demographically similar to themselves as having greater perceived inherent …

Deciphering The Crl Code: Novel Mechanisms Of Canonical And Non-Canonical Ubiquitylation, Nicholas Wayne Purser

UNLV Theses, Dissertations, Professional Papers, and Capstones

Protein degradation is a fundamental process required for maintaining cellular homeostasis in eukaryotic organisms. In humans, distinct cell types exhibit unique proteomic landscapes that are dynamically balanced by the continual synthesis and degradation of proteins. The timely removal of damaged, misfolded, or old proteins is essential to permit new protein synthesis and to ensure proper cellular function.

Central to this regulatory network is ubiquitylation, a highly conserved posttranslational modification system that governs protein stability and function across all eukaryotic cells. Through the covalent attachment of ubiquitin molecules to protein substrates, this system modulates a broad range of biological processes, including …
