Essays On Firm Productivity And Innovation, Won Sung
Essays On Firm Productivity And Innovation, Won Sung
Legacy Theses & Dissertations (2009 - 2024)
Firms’ productivity gain and technological innovation have been vital to ensure a country’s long-term economic growth and competitive advantage. This dissertation focuses mainly on drivers and barriers nurturing to firms’ productivity gains and innovative activities to suggest policy implications. The first essay examines the impacts of inventor mobility in value creation in mergers and acquisitions (M&As). We employ a two-sided matching model for acquirers and targets that allows them to choose whom to merge with. Applying this model, we examine how inventor mobility affects value creation in M&As in the manufacturing sector. Inventors exchanged between inventing firms have been interpreted …
Translation Control Tunes Drosophila Oogenesis, Elliot T. Martin
Translation Control Tunes Drosophila Oogenesis, Elliot T. Martin
Legacy Theses & Dissertations (2009 - 2024)
The decision of a stem cell to either self-renew or differentiate is controlled by specific cellularpathways that can act at the level of transcription, translation, or post-translation. To study the regulation of these pathways in-vivo, I have used the female Drosophila germline as a model system. Each of the steps from germline stem cell (GSC) to egg require changes in cellular pathways. These changes can occur at the level of transcription, post-transciption, translation, or post-translation . Decades of research has elucidated many of the changes to gene that occur during oogenesis, however, many players in this process still remain mysterious. …

Role Of H3k4 Methylation In Myogenesis, Regeneration, And Muscle Disease / Narrative Competence And Cognitive Mapping As A Culturally Sustaining Pedagogy In The Education Of Emergent Bilinguals, Hannah Emily Shippas
Legacy Theses & Dissertations (2009 - 2024)
Muscles are a crucial part of an organism’s wellbeing, as defects in distinct types of muscles can be lethal. Our voluntary muscles, skeletal muscles, go through distinct regeneration phases before reaching maturity. With its own pool of stem cells, muscles have a large potential for regeneration. This potential has led scientists into looking closely at the steps that lead a muscle stem cell into muscle fiber, also known as myogenesis. As a muscle cell moves through myogenesis, genes are led to be turned on/off with different epigenetic mechanisms, one being histone modifications. A methylation modification on the 4th Lysine on …
The Influence Of Loneliness : Mental Health's Impact On Workaholism Among Graduate Students, Bhindai Mahabir
The Influence Of Loneliness : Mental Health's Impact On Workaholism Among Graduate Students, Bhindai Mahabir
Legacy Theses & Dissertations (2009 - 2024)
Graduate students are the principal proponents of academia and its ecosystem. In addition to challenging curriculums, teaching and research responsibilities, caregiving demands, and lingering student loans, graduate students are also particularly vulnerable to stress. These factors all adversely affect graduate students' mental health. Using longitudinal data from 247 graduate students over the span of six months, this study examines how self-reported depression and anxiety may influence graduate students’ workaholism through increased loneliness based on the mood congruency judgment effect. Further, graduate students are often surrounded by students in the same program and classes who share similar experiences and with whom …
Comparative Effectiveness Of Behavioral Interventions For Mus : A Meta-Analysis, Justin Kimber
Comparative Effectiveness Of Behavioral Interventions For Mus : A Meta-Analysis, Justin Kimber
Legacy Theses & Dissertations (2009 - 2024)
Medically unexplained symptoms (MUS) are common: 25 to 50% of patients seen in primary care present with MUS (e.g., fibromyalgia, irritable bowel syndrome, and chronic fatigue). Patients with MUS report higher symptom severity, psychological distress, and poorer functioning and quality of life than patients without MUS. To address the needs of patients with MUS, behavioral interventions (e.g., cognitive behavior therapy and exercise) have been used to improve patient outcomes including symptom severity, psychological distress, and quality of life. To date, behavioral interventions have been shown to be efficacious to improve patient outcomes; however, less is known about the comparative efficacy …
Indicators And Warnings Of Russian Military Offensives, Evan Essex
Indicators And Warnings Of Russian Military Offensives, Evan Essex
Legacy Theses & Dissertations (2009 - 2024)
Russia’s invasion of Ukraine on February 24, 2022 was the only Russian military offensive that had adequate warning that the Russians would invade. The four previous instances of Russian military operations including intervention in Moldova (1992), invasion of Georgia (2008), annexation of Crimea (2014), and support for separatists in Eastern Ukraine (2014) all occurred without warning that Russia was going to invade and consequently, those target countries had no time to prepare. If NATO, allied combatant commanders, as well as their respective intelligence organizations want to be able to prepare and effectively respond in the future to Russian military operations, …
Hierarchical Modelling Of Raman Spectroscopic Data Demonstrates The Potential For Manufacturer And Caliber Differentiation Of Smokeless Powders, Nathan Russell Bartlett
Hierarchical Modelling Of Raman Spectroscopic Data Demonstrates The Potential For Manufacturer And Caliber Differentiation Of Smokeless Powders, Nathan Russell Bartlett
Legacy Theses & Dissertations (2009 - 2024)
With the rise of gun-based crime and the advent of lead-free ammunition reducing the effectiveness of previously used methods, the analysis of smokeless powders to better understand organic gunshot residues is now more important than ever. One method that has shown potential is Raman spectroscopy, a relatively quick, nondestructive, and non-contact analysis method. To investigate whether Raman spectroscopy could be used to characterize individual powders, samples of smokeless powders from three manufacturers, Remington, Federal, and Winchester, each with two 9mm caliber and two .38 caliber ammo types, were dissolved, and their Raman spectra were collected. A hierarchical modelling system was …

Exploring The Response To Arsenic Using Trna Modification Detection, Writer Mediated Protection And Codon Usage Analytics, Anwesha Sarkar
Legacy Theses & Dissertations (2009 - 2024)
Transfer ribonucleic acid (tRNA) is a non-coding RNA which interacts with the messenger RNA (mRNA) to facilitate protein synthesis. tRNA is also one of the most heavily modified RNAs with the collection of modifications, termed as the tRNA epitranscriptome, ranging from simple methylation to complex hypermodification catalyzed by RNA epitranscriptomic writers. Detecting tRNA modifications is an evolving field and the state-of-the-art technologies that include next generation sequencing and mass spectrometry of intact and derivatized RNAs is described in the chapter one. Liquid chromatography coupled with mass spectrometry has previously been used to show that arsenic promotes increases in the levels …

Relationships Of Teacher Perceptions And Racially Diverse Third Grade Student Achievement : An Analysis Of Ecls-K:2011 Data University At Albany, Lynnette Renee Williams
Legacy Theses & Dissertations (2009 - 2024)
ABSTRACTIt has been over 50 years since desegregation efforts began and many public-school systems in the United States are still battling with performance gaps between White and historically underrepresented students. The term historically underrepresented refers to people from diverse racial, cultural, linguistic, and economically disadvantaged backgrounds who have been denied access or suffered institutional discrimination in the United States, and according to the U.S. Census includes Blacks/African Americans, Asian Americans, Hispanics, and Native Americans (Artiles et al., 2010). Many historically underrepresented students are lagging behind their peers on academic performance measures, standardized achievement tests, high school graduation, and college-career readiness …
An Iterative Theory Of The Legislative Process : A Case Study Of The New York State Commission On Prosecutorial Conduct, Kimberly M. Bernstein
An Iterative Theory Of The Legislative Process : A Case Study Of The New York State Commission On Prosecutorial Conduct, Kimberly M. Bernstein
Legacy Theses & Dissertations (2009 - 2024)
Prosecutors wield the power of the criminal justice system (Medwed, 2014) and the ability to deprive a person of their constitutional rights (Imbler v. Pachtman, 1976). With such power, it is unsurprising that a leading cause of miscarriages of justice is prosecutorial misconduct (e.g., Joy, 2006; Ridolfi & Possley, 2010). New York State became the first state in the country to respond to this issue with a specialized Commission on Prosecutorial Conduct (CPC). The goal of the CPC is to serve as an official mechanism for holding District Attorneys and Assistant District Attorneys accountable by challenging convictions and handing down …
Environmental Factors And Human Health Interactions : Ultrafine Particles, Temperature Variability, And Proximity To Power Stations, Ian Ryan
Legacy Theses & Dissertations (2009 - 2024)
Background: Air pollution leads to more than four million premature deaths worldwide and nearly 200,000 in the US each year. While there is extensive research relating PM2.5 to hospital visits for various health outcomes, there is relatively little research on ultrafine particles (UFPs), a particularly small and dangerous air pollutant. Another important exposure is temperature due to its association with dehydration, heat stress, and cardiovascular-related hospital admissions. However, relatively little research has been conducted on diurnal temperature range (DTR), or the range of temperature within a single day, which is an important indicator of climate change. Importantly, the interaction between …

The Long Island Opt-Out Movement And Local Politics In Four School Districts, Raymond James Webb
Legacy Theses & Dissertations (2009 - 2024)
This study focused on the political influence of the Long Island Opt-Out Organization, an interest group that promoted the right of parents and guardians to have their children opt out of standardized testing. The study examined the activism and influence of this group on school board elections and policy agendas in four school districts in Long Island, New York during 2014-2019.
The Dark Figure Of Wrongful Convictions : How Intake Decisions Impact Exonerations, Jennifer Weintraub
The Dark Figure Of Wrongful Convictions : How Intake Decisions Impact Exonerations, Jennifer Weintraub
Legacy Theses & Dissertations (2009 - 2024)
Innocence organizations contributed to 45% of exonerations in the year 2020, and account for nearly 25% of all U.S. exonerations. Yet little is known about these organizations, including a review of their intake criteria and procedures, how they select their intake criteria and procedures, or how those choices influence the landscape of known wrongful convictions. The contents of these intake decisions as well as how they are chosen have implications for what is currently known about wrongful convictions nation-wide. In this study, 19 innocence organizations represented by 24 innocence organization staff and leaders completed qualitative interviews to address this gap …
Addressing The Scale Issues In Spatial-Temporal Analysis Of Crime : An Integrative Framework And Empirical Findings, Mohammed Abdulrazak Alazawi
Addressing The Scale Issues In Spatial-Temporal Analysis Of Crime : An Integrative Framework And Empirical Findings, Mohammed Abdulrazak Alazawi
Legacy Theses & Dissertations (2009 - 2024)
Based on a critical review of existing literature in the spatial-temporal analysis of crime, three challenges have been identified: spatial-temporal scaling, theorizing spatial patterns for different types of crime, and the micro interaction between space and time. The spatial-temporal scaling issue is related to choosing the appropriate geographic unit of analysis. The theoretical issue concerns the lack of an integrative approach that can integrate the benefits of each theoretical perspective and identify broader processes to explain the resulting spatial patterns for different types of crime. Also, examining and explaining the variation of the micro space-time interactions for different types of …
Battlefield Women: How Nurses, Soldiers, And Spies Challenged Gender Roles During The American Civil War, Kaitlyn Thomas
Battlefield Women: How Nurses, Soldiers, And Spies Challenged Gender Roles During The American Civil War, Kaitlyn Thomas
History Honors Program
My research has focused on specific women in the Civil War that held the occupation of soldier, spy/scout, nurse or camp follower during the war and how their work in the war challenged the gender roles of the 1800s. I argued that the war has been an agent of change as women were able to hold male dominated roles that were involved in the war. While most of these women had not gone in with the intention of challenging those gender roles, those women had indirectly done so. To help with this project I have analyzed many sources to help …

Franco’S Failed War Of Legitimacy: Constructing The Historical Memory Of The Spanish Civil War In Education., Cameron Cupp
History Honors Program
In 1939, General Francisco Franco rose to power as a result of his victory in the Spanish Civil War. The Spain he ruled over was war-torn and fractured, grieving over lost loved ones and burning towns. As he looked to repair Spain, Franco turned to education. He entrusted the Catholic Church to administer his new curriculum which looked to accomplish one goal: indoctrinate Spanish youth into a new generation of National-Catholic sycophants. Although this goal seemed sound, Franco and his disciples failed to build upon their foundational legitimacy, which I argue was the fear and terror inflicted upon the public …
Composing An Identity: How Musicians And Scholars Of The Mid-Twentieth Century Utilized The Sevdalinka To Establish A Modern Bosniak Identity, Aida Hrustić
History Honors Program
This paper explores how musicians and scholars contributed to the development of a modern Bosniak identity during the mid-twentieth century through their utilization of the sevdalinka. Many historians and scholars have studied the relationship between the sevdalinka and the Bosniaks and recognized its significance but have overlooked the impact sevdalinka musicians and scholars of the mid-twentieth century had in ushering in a modern Bosniak identity. This paper discusses how the growth of the music industry elevated the status of sevdalinka musicians in society and within the Bosniak community, deepening the Bosniak community’s tie to the sevdalinka through their musical work …
Gender Differences In Labor Market Outcomes During The Covid-19 Pandemic, Cassidy Bowes
Gender Differences In Labor Market Outcomes During The Covid-19 Pandemic, Cassidy Bowes
Economics
In the events of the COVID-19 pandemic, the Department of Homeland security released guidelines on who would be an essential worker and required to keep going to work for the benefit of society. Two of the industries deemed essential were healthcare and education, both of which are heavily concentrated by female workers. In this study, I use Current Population Survey data spanning November 2019 to December 2021 to test for gender differences in earnings among those working in the healthcare and education occupations during the pandemic. I estimate a regression model which includes controls for time trends and other factors, …

The cities data are based on four independent variables, those being population, demographics, police budget in 2020, and persons in poverty. This study will analyze if these four independent variables will influence the dependent …
An Examination Of Historical Health Disparities Of The Black Population In America, And Their Effects On Contemporary Health Disparities In Covid-19 Vaccine Hesitancy, Sophia-Evelyne Blake Nehama
An Examination Of Historical Health Disparities Of The Black Population In America, And Their Effects On Contemporary Health Disparities In Covid-19 Vaccine Hesitancy, Sophia-Evelyne Blake Nehama
Public Health Undergraduate Program
The COVID-19 pandemic has highlighted the significant health disparities that the African American population faces in comparison to White Americans. The Tuskegee Syphilis study is often cited to support the theory that medical mistrust is responsible for these disparities despite conflicting opinions that medical distrust is not the main reason for disparities. This study examines the effects that historical health disparities in Black populations have on contemporary vaccine hesitancy. An analysis of recent sources, including peer reviewed historical analysis and news articles with accredited sources was used to make up the entirety of the literary review. For data on contemporary …

Raman Spectroscopy Of Aged Waterlogged Bones: Protocol Optimization, Bailey Hoplight
Raman Spectroscopy Of Aged Waterlogged Bones: Protocol Optimization, Bailey Hoplight
Chemistry
Current methods used for determining the age buried bones for forensic purposes are heavily affected by environmental conditions, can be susceptible to scientific bias and the interpretation can vary from investigator to investigator. Raman Spectroscopy can potentially be used as an automatic method to analyze the composition of bone eliminating the human factor. To test this hypothesis, we will use Raman spectroscopy to potentially identify the burial time of bones. The change in the chemical composition of the pig bones was probed using a Raman spectrometer with a 785nm excitation wavelength. Other parameters of the Raman instrument were optimized to …
Optophysiology Of D. Melanogaster Neuromuscular Synapses Using Gcamp, Kavindra Dasrat
Optophysiology Of D. Melanogaster Neuromuscular Synapses Using Gcamp, Kavindra Dasrat
Biological Sciences
An activity-dependent increase in postsynaptic currents produced by a single vesicle of neurotransmitter is an important mechanism for synaptic plasticity in the central nervous system (CNS) and possibly involved in learning and memory. We have found a similar form of postsynaptic potentiation at the D. Melanogaster neuromuscular junction (NMJ) where a brief increase in impulse activity results in an increase in the amplitude of spontaneous miniature excitatory postsynaptic currents (mEPSCs), resulting in miniature excitatory postsynaptic potentials (mEPSPs). To visualize sites of postsynaptic potentiation along the synaptic terminal, we have used a Ca2+ indicator, GCaMP to observe postsynaptic Ca2+ signals. Since …
Potentially Cis-Acting Super-Enhancer Long Noncoding Rnas As Biomarkers In Triple Negative Breast Cancer Progression, Kavipriya Kovai Palanivel
Potentially Cis-Acting Super-Enhancer Long Noncoding Rnas As Biomarkers In Triple Negative Breast Cancer Progression, Kavipriya Kovai Palanivel
Biological Sciences
Triple negative breast cancer (TNBC) is defined by the lack of estrogen receptors (ER), the lack of progesterone receptors (PR), and normal human epidermal growth factor 2 (HER2) protein levels in breast tumors. Therefore, TNBC is an aggressive type of breast cancer due to limited treatment options for patients. Determining genes that regulate the progression of tumors to TNBC may help develop new therapeutic techniques. Many super-enhancer long noncoding RNAs (SElncRNAs) are found to be differentially expressed in cancer cells. Super-enhancer activity heavily influences target gene transcription and is often augmented through cis-acting SE-lncRNA activity. Therefore, we hypothesize cis-acting SE-lncRNAs …
Emerging Roles Of Intragenic Enhancers In Gene Expression Of Gadd45a, Ekaterina Sazon
Emerging Roles Of Intragenic Enhancers In Gene Expression Of Gadd45a, Ekaterina Sazon
Biological Sciences
Non-coding regulatory elements in the eukaryotic genomic DNA, like enhancers and promoters, control gene expression. Transcription factors recognize and bind to DNA sequences within these regulatory regions and affect said regulatory elements. The extent and specific circumstances regarding transcription factors are long-standing questions in the field. In this thesis, we wanted to investigate how transcription factors work in a particular case of enhancers, known as intragenic enhancers. We designed reporter gene assays that looked at the well-studied model transcription factor p53’s regulation on its target gene GADD45A in basal and stress conditions. We determined that GADD45A is a p53-dependent gene, …
Toward Long Non-Coding Rna Detection Using Dna Nanoswitches, Ché-Doni Platt
Toward Long Non-Coding Rna Detection Using Dna Nanoswitches, Ché-Doni Platt
Biological Sciences
Long non-coding RNAs (lncRNAs) are transcripts that are over 200 nucleotides and do not encode proteins. LncRNAs are involved in a wide spectrum of biological processes ranging from cell proliferation, apoptosis, and nutrient sensing to cell differentiation. Further, lncRNAs have been reported to play an important role in a wide range of pathophysiological processes and are linked to diseases such as cancer. Thus, lncRNAs are becoming increasingly important as biomarkers to study biological and disease processes. In our work, we develop a DNA nanoswitch-based assay for detecting long RNAs. The DNA nanoswitch is a reconfigurable device that undergoes a conformational …
Circadian Modulation Of Astrocyte Morphology And Synaptic Transmission, Saad Ahmad
Circadian Modulation Of Astrocyte Morphology And Synaptic Transmission, Saad Ahmad
Biological Sciences
The circadian rhythm affects behavior and physiology in many animal species. Our previous work in mice showed that within the hippocampus, a subordinate circadian oscillator, astrocytes change their proximity to excitatory synapses. Here we obtain 3D reconstructions of biocytin-filled hippocampal astrocytes processed with protein retention expansion microscopy and imaged using two-photon laser scanning microscopy. Our findings identify the subtle changes in astrocyte morphologies that encode information about time-of-day in hippocampal astrocytes. These findings shed light on fundamental mechanisms that allow the function of hippocampal circuits to adapt to different times of the day. This will help us understand how structural …
Investigating The Roles Of Rna Modification And Associated Enzymes On Stress Response And Connections To Human Diseases, Carrson Widen
Investigating The Roles Of Rna Modification And Associated Enzymes On Stress Response And Connections To Human Diseases, Carrson Widen
Biological Sciences
Transfer RNAs decode messenger RNA using anticodon – codon interactions to deliver specific amino acids to a growing peptide chain. Enzyme-catalyzed modifications on specific nucleotides on tRNAs increase their stability and help mediate the speed and fidelity of translation, giving these modifications regulatory potential. RNA modifications are catalyzed by writer enzymes, and I predicted that writers are important in the cellular responses to stress. I have evaluated the following E. coli modification enzyme mutants: miaA, mnmE, dtd, tmcA, lysU, yeaK, and iscS, from the corresponding Keio E. coli gene deletion library. Writer mutants were exposed to hydrogen peroxide to induce …
Using The Centrifuge Force Microscope As A Single-Molecule Technique For Studying Base-Stacking Interactions, Kevin Thomas
Using The Centrifuge Force Microscope As A Single-Molecule Technique For Studying Base-Stacking Interactions, Kevin Thomas
Biological Sciences
A wide range of single-molecule techniques has streamlined the process of applying and studying the effects of force on individual molecules. The centrifuge force microscope (CFM) is one such technique that allows for high-throughput single-molecule pulling experiments. It is relatively inexpensive and user-friendly, making it a suitable tool to study the effects of force on various biomolecular interactions. A benchtop centrifuge can be used to apply centrifugal force to molecular constructs that are tethered between a glass slide and a microsphere. Molecular events like bond dissociation result in the removal of the microsphere from the surface, which is observed by …
