Spatial Pattern Of Urban Heat Signature And Its Impact On Pamoyanan Village, Cianjur District, V S. Sunukanto, Jarot Mulyo Semedi, Iqbal Putut Ash Shidiq, Norizah Kamarudin, Adi Wibowo

Jurnal Geografi Lingkungan Tropik (Journal of Geography of Tropical Environments)

According to the World Bank's Climate Change Knowledge Portal in 2020, the increase in annual temperature in Indonesia, which tends to rise by 0.3°C, is consistent with the Urban Heat phenomenon. Population growth and shifting land cover contribute to annual temperature fluctuations by reducing the amount of vegetated land. The increase in temperature in the urban environment has particular impacts on the community in terms of environmental changes. The term "Urban Heat Signature" refers to land cover in a localized urban environment with natural consequences due to solar radiation and high-low temperature values. This study was conducted in Pamoyanan Village, …

Spectroscopic Studies Of The Interaction Between Phosphorus Heterocycles And Cytochrome P450, Dumei Ma, Libo Zhang, Yingwu Yin, Yuxing Gao, Qian Wang

Faculty Publications

P450 fatty acid decarboxylase OleT from Staphylococcus aureus (OleT_SA) is a novel cytochrome P450 enzyme that catalyzes the oxidative decarboxylation of fatty acids to yield primarily terminal alkenes and CO₂ or minor α- and β-hydroxylated fatty acids as side-products. In this work, the interactions between a series of cycloalkyl phosphorus heterocycles (CPHs) and OleT_SA were investigated in detail by fluorescence titration experiment, ultraviolet–visible (UV–vis) and ³¹P NMR spectroscopies. Fluorescence titration experiment results clearly showed that a dynamic quenching occurred when CPH-6, a representative CPHs, interacted with OleT_SA with a binding constant value of 15.2 …

Agent Based Modeling Of The Spread Of Social Unrest Based On Infectious Disease Spread Model, Anup Adhikari

School of Computing: Dissertations, Theses, and Student Research

Social unrest activities are the tools for people to show dissatisfaction, and often people are motivated by similar unrest activities in another region. This causes a spread of unrest activities across space and time. In this thesis, we model the spread of social unrest across time and space. The underlying novel methodology is to model the regions as agents that transition from one state to another based on changes in their environment. The methodology involves (1) creating a region vector for each agent based on socio-demographic, cultural, economic, infrastructural, geographic, and environmental (SCEIGE) factors, (2) formulating neighborhood distance function to …

Genome Annotation Using Average Mutual Information, Garin P. Newcomb

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

Advancements in high-throughput DNA sequencing technologies and ambitious goals for their use are resulting in the generation of a deluge of unannotated sequenced genomes. This makes computational tools that can aid in annotation increasingly valuable.

Here, we provide a detailed exploration of the utility as well as the limitations of average mutual information (AMI) in several steps of genome annotation. For a genomic sequence, AMI is a measure of the information a base contains about the base separated by a fixed lag. A profile is constructed by calculating AMI at multiple lags. In addition to traditional AMI, we employ two …

Risk-Based Machine Learning Approaches For Probabilistic Transient Stability, Umair Shahzad

Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research

Power systems are getting more complex than ever and are consequently operating close to their limit of stability. Moreover, with the increasing demand of renewable wind generation, and the requirement to maintain a secure power system, the importance of transient stability cannot be overestimated. Considering its significance in power system security, it is important to propose a different approach for enhancing the transient stability, considering uncertainties. Current deterministic industry practices of transient stability assessment ignore the probabilistic nature of variables (fault type, fault location, fault clearing time, etc.). These approaches typically provide a conservative criterion and can result in expensive …

Comparative Analysis Of Kmer Counting And Estimation Tools, Ankitha Vejandla

School of Computing: Dissertations, Theses, and Student Research

The rapid development of next-generation sequencing (NGS) technologies for determining the sequence of DNA has revolutionized genome research in recent years. De novo assemblers are the most commonly used tools to perform genome assembly. Most of the assemblers use de Bruijn graphs that break the sequenced reads into smaller sequences (sub-strings), called kmers, where k denotes the length of the sub-strings. The kmer counting and analysis of kmer frequency distribution are important in genome assembly. The main goal of this research is to provide a detailed analysis of the performance of different kmer counting and estimation tools that are currently …

Time To Mail It In? A Survey Of 2020 Voting Rights Issues In Arkansas And Recommendations For More Inclusive Elections, Kim Vu-Dinh

University of Arkansas at Little Rock Law Review

The highly contagious COVID-19 pandemic, combined with over fifty lawsuits brought by former President Donald Trump, made the general election of 2020 one of the most controversial in the history of the United States. Accusations of voter disenfranchisement proliferated across the nation and were initiated by members of both sides of the political spectrum, even before Election Day. Arkansas was no exception to this rule. In 2020, multiple Arkansas lawsuits highlighted the weaknesses of the state’s voter infrastructure, particularly with regard to the absentee ballot process. Voting-by-mail was particularly important in the pandemic year when long lines became a public …

Cover Crop Effects On Near-Surface Soil Aggregate Stability In The Southern Mississippi Valley Loess (Mlra 134), Chandler M. Arel

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

Intensive agricultural cultivation within major land resource area (MLRA) 134, the Southern Mississippi Valley Loess, has led to soil erosion, soil compaction, and the overall destabilization of near-surface soil aggregates. The use of cover crops during the agricultural offseason has been shown to help alleviate soil compaction and provide stabilizing effects against soil erosion, which are particularly important as the silty soils of MLRA 134 have a large erosion potential. This study evaluated the effects of cover crop and no-cover crop treatment on silt-loam soils within MLRA 134. Treatments were implemented during Fall 2018 and Fall 2019 and consisted of …

Prenatal Exposure To Per- And Polyfluoroalkyl Substances And Child Neurodevelopment, Jiwon Oh

Earth & Environmental Sciences Dissertations - Archive

Pregnant women are exposed to per- and polyfluoroalkyl substances (PFAS) primarily via ingestion of contaminated food, water, and house dust. PFAS in pregnant women can be transferred to their child through the placenta during pregnancy. Many long-chain PFAS have been frequently detected in blood of pregnant women, amniotic fluid, and umbilical cord blood for the last few decades. Prenatal exposure to PFAS has shown potential to adversely affect offspring’s neurodevelopment in laboratory animals. However, epidemiological evidence on associations between prenatal PFAS exposure and child neurodevelopment remains inconsistent. My dissertation research consists of four sub-studies whose objectives are (1) to examine …

This investigation aimed to develop simple, effective, and economical models that can be used to identify different attributes of the originator. The focus of this research was to develop biocatalytic cascades that could analyze body fluids by using UV-Vis spectroscopy. These models could be implemented in forensic settings, as well as in biometric authentications. The central …

The Impacts Of Transported Wildfire Smoke Aerosol On Surface Air Quality In New York State, Wei-Ting Hung

Legacy Theses & Dissertations (2009 - 2024)

In New York State (NYS), summertime long-range transported smoke plumes and high fine mode particulate matter (PM2.5) concentration during the smoke episodes have been reported. Since the frequency, intensity, and burned area of wildfires over Northern America have increased in recent years, the contribution of transported smoke aerosols to local air quality could become more significant. This study aimed to characterize the transport of smoke aerosols and quantify their impacts on the local air quality over NYS. A case study of a transported smoke event in mid-August of 2018 and multi-year analysis of the smoke cases during the summer seasons …

The Contributions Of Dynamical And Diabatic Processes Preceding And Accompanying Major Greenland Ice-Melt Events, Scott Feldman

Legacy Theses & Dissertations (2009 - 2024)

Extratropical cyclones and/or short-wave disturbances can reinforce Greenland blocking through upper-level flow amplification and can increase poleward heat and moisture transport into the Arctic. Increased poleward heat and moisture transport into the Arctic may enhance Greenland ice melt during the spring, summer, and fall months. The need to better understand the underlying dynamical and diabatic processes that may contribute to Greenland ice melt motivates this thesis. The purpose of this thesis is to investigate: 1) the role of advective warming due to poleward heat and moisture transport into the Arctic in facilitating Greenland ice melt, 2) the role of adiabatic …

Economic Sanctions And Opportunism, Keith A. Preble

Legacy Theses & Dissertations (2009 - 2024)

Sanctions busting refers to instances where third-party states increase their material support for states targeted by economic sanctions by increasing trade as well as foreign aid and investment, which, in turn, minimize the economic costs that sanctions imposed on target states. This concept privileges the sender and contributes to the “sender bias” inherent in the literature on economic sanctions. My dissertation instead argues that the terms sanctions opportunism may better reflect the nature of the processes at work when third-party states engage in sanctions busting either for commercial profit or as a “black knight” (or a combination of them both). …

Social Identities At Work : How Do Multiple Social Identities Influence Organizational Attraction?, Aileen Dowden

Legacy Theses & Dissertations (2009 - 2024)

Social Identity Theory posits that people hold a social identity from which they derive meaning to groups and organizations they join. That individuals use group affiliation to serve social identity concerns is a hallmark of social identity theory. In these studies, two social identity concerns were tested, social adjustment and value expression, to examine if people could hold both or neither concerns simultaneously (study 1) and how they influenced attraction to organizations (study 2). For study 1, archival data was analyzed using latent class analysis to extract groups of respondents for different levels of social identity concerns. Five classes were …

Image Data Analysis And Design Optimization Of The Snowball Chamber, Yujia Huang

Legacy Theses & Dissertations (2009 - 2024)

Dark Matter is the invisible massive particle that makes up over 26.8 percent of the mass-energy content of the universe. Weakly Interacting Massive Particles, or WIMPs, are one of the candidates of dark matter particles. Many scientists around the world are trying to figure out how to detect detect dark matter using either indirect search, direct production or direct detection experiments. However, due to the lack of evidence of finding WIMPs in direct detection experiments at a large mass scale, a call for investigating WIMPs at a lower mass range is attracting more attention.

Are There Individual Differences In The Foreign Language Effect?, Rita Gross

Legacy Theses & Dissertations (2009 - 2024)

AbstractA foreign language effect (FLE) occurs when the language a problem is presented in influences its outcome (Keysar et al., 2012). So far, it has been unclear under which conditions the FLE appears (Driver, 2020; Dylman & Champoux-Larsson, 2020). One hundred and sixty-eight Arabic-English bilinguals from Prince Sultan University were presented with the Trolley Dilemma (a low-conflict, impersonal moral dilemma) and the Footbridge Dilemma (a high-conflict, personal moral dilemma) and responses to these dilemmas were measured on a slider indicating likeliness to take a suggested action. Participants saw Dilemmas either in a gain-frame or a loss-frame condition, and in either …

Properties Of Curriculum-Based Measurement For Mathematics : An Investigation Of The Average Growth, Variability, And Precision Of Three Forms, Arianna Doss

Legacy Theses & Dissertations (2009 - 2024)

CBM for mathematics assesses growth in accuracy and fluency of basic math skills using content from a student’s curriculum. CBM for mathematics can include single-skill measures (SSM), skill-based measures (SBM), and general-outcome measures (GOM). Past research on growth rates in CBM for mathematics has focused on GOMs and has relied on estimations of weekly growth rates, but more information on expected growth rates and their precision for these measures is needed for practice. The current study addresses this gap in the literature by examining weekly growth rates and their precision for one SSM containing multiplication problems, one SBM containing addition …

Reliability Characterization Of A Low-K Dielectric Using Its Magnetoresistance As A Diagnostic Tool, Philip Alister Williams

Legacy Theses & Dissertations (2009 - 2024)

The introduction of low dielectric constant materials within the integrated circuit (IC) chip technology industry was a concerted effort to decrease the resistance-capacitance (RC) time delay inherent within the dielectric materials used as insulators. This stems from a demand for greater device density per IC chip and decreased feature sizes but is fast becoming a reliability issue. Concomitant with the demand for decreased feature sizes, also in adherence with Moore’s Law (which states that the number of devices on a die doubles every two years), is a reduction in device speed and performance due to device intra-level interconnection signal delays. …

1,4-dioxane is a volatile organic compound categorized by the United States Environmental Protection agency (EPA, 2017) as a possible human carcinogen potent to cause tumors in humans. Even though this compound poses significant environmental danger when it contaminates water sources, it is surprisingly less studied, and how it behaves in surface water is less understood. The biggest 1,4-dioxane plume in the United States is located in Long Island region of New York. The purpose of this study was to investigate the presence of 1,4-dioxane in surface water and document the influence of existing 1,4-dioxane plume to Twin Lakes Preserve. To …

Development Of Sense Of Place Through An Urban Citizen Science Program, Cornelia Harris

Legacy Theses & Dissertations (2009 - 2024)

Citizen science programs are a way for participants to develop a sense of place, which has been theorized to lead to pro-environmental behaviors. In this mixed-methods study, I document how a citizen science program encourages urban youth to connect with their place, and notice how both joy and wonder are developed as they experience a stunning migratory event with a unique organism, the American eel. Students were excited to be in a creek and to ‘discover’ a new creature in a place that they had walked past for years, one that was merely a backdrop to their lives prior to …

Entropic Density Functional Theory : Entropic Inference And The Equilibrium State Of Inhomogeneous Fluids, Ahmad Yousefi

Legacy Theses & Dissertations (2009 - 2024)

A unified formulation of the density functional theory is constructed on the foundations of entropic inference in both the classical and the quantum regimes. The theory is introduced as an application of entropic inference for inhomogeneous fluids in thermal equilibrium. It is shown that entropic inference reproduces the variational principle of DFT when informationabout expected density of particles is imposed. In the classical regime, this process introduces a family of trial density-parametrized probability distributions, and consequently a trial entropy, from which the preferred one is found using the method of Maximum Entropy (MaxEnt). In the quantum regime, similarly, the process …

The Effects Of Doula Care On Birth Outcomes And Patient Satisfaction In The United States, Lynae Carlson

The Eleanor Mann School of Nursing Undergraduate Honors Theses

The visitor policies related to the COVID-19 pandemic limited doula care and called into question the importance of doulas in the birth process. While the Cochrane Systematic Review presents compelling evidence of the benefits of continuous birth support on outcomes ranging from shorter labors to higher 5-minute Apgar scores, there are gaps in literature that exclusively focus on continuous support from doulas. The literature review aims to determine both qualitative and quantitative outcomes of doula care on the mother and baby during the labor and post-partum periods, focusing on specific aggregates, such as adolescents, women with low incomes, and women …

Community Perspective: How Participating In The Nutcracker Enhances Student Motivation And Growth In Socioeconomically Depressed Public Schools, Angelina Burleigh

Master's Theses

This research study exclusively focused on performing arts dance programs in socioeconomically depressed public schools. It is the belief of this researcher that providing dance within a framework of the dance standards affords students with the opportunity to truly experience the art of dance, since they not only received the chance to learn good technique from a highly qualified educator, but they are also provided with choreographic and performance opportunities which allow them to communicate a story, express feelings, or emotions through movement to discover their imaginative abilities. The goal of this study was to examine how dance education impacts …

Photoacoustic-Guided Endovenous Laser Ablation: Characterization And In Vivo Canine Study, Yan Yan, Samuel John, Tanyeem Shaik, Bijal Patel, Mai T. Lam, Loay S. Kabbani, Mohammad Mehrmohammadi

Surgery Articles

Endovenous laser ablation (EVLA) is a minimally invasive surgical procedure, often guided by ultrasound (US) imaging, for treating venous insufficiencies. US imaging limitations in accurately visualizing the catheter and the lack of a temperature monitoring system can lead to sub-optimal outcomes. An integrated photoacoustic (PA)-guided EVLA system has been previously developed and reported to overcome the shortcomings of US-guided procedure. In this study, we further characterized the system and tested the in vivo utility. In addition, PA thermometry was further explored by compensating the variation of PA signal with temperature with respect to the temperature-dependent absorption of blood and water. …
