Effects Of Macronutrients Intake And Physical Activity On Childhood Obesity Of Hispanic Children, Prosanta Barai

Theses and Dissertations

Obesity has become more ubiquitous during the past few decades, and still, its prevalence is increasing. It is in every population in the world and all regions, including rural parts of low and middle-income countries. In the USA, regardless of age, the severity of obesity is no different from the global trend. Although numerous pieces of literature are available, that tried to find answers to some pressing issues like how obesity can be controlled, but there is little to no study focused on younger children, especially the 4-6-year-old Hispanic population. Our study aimed to determine the causal path among literature …

Body Composition, Muscular Strength, Arterial Stiffness, And Hemodynamics Responses To Various Training Protocols In Young Males, Jorge Bejar

Theses and Dissertations

PURPOSE: The purpose of this study was to compare the effects of 8 weeks performing various resistance training protocols with and without blood flow restriction (BFR) on muscular strength, body composition, arterial elasticity, and hemodynamics responses in young males.

RESULTS: Significant time*condition interactions occurred in HR period (p <0.05), HDI SBP (p <0.05), HDI MAP (p <0.05), and SV (p <0.05). Trends for time*condition interactions were found in HDI DBP (p=0.054), HDI HR (p=0.051), and HDI SVR (p=0.085). Significant time main effects occurred in all strength measures (p <0.05). Significant condition main effects occurred in Aortic DBP (p <0.05), Brachial DBP (p <0.05), and LAE (p <0.05). Total lean mass significantly increased from baseline the HI condition only (p<0.05).

CONCLUSION: Significant improvements in lean mass were seen following the HI and BFR protocols. However, decreases in LAE were found following the HI protocol only. It appears that performing aerobic exercise after resistance training can negatively affect muscle growth. However, only 15 min of moderate-intensity aerobic training can improve hemodynamics in young, …

Tap Water Disinfection In The Electrochemical Precipitation Process By Using Novel Conductive Concrete, Md Shoriful Islam

Theses and Dissertations

Electrochemical precipitation (EP) is tested to learn about its impact on disinfectants in tap water. The EP process involves applying electricity through electrodes submerged in water to precipitate dissolved metals like water hardness out without chemical additives. In the study, tap water was tested to learn about EP’s impact on disinfectants. Tap water contains not only hardness but also residual disinfectants. It is very essential for the safety of drinking water against the potential ingress of pathogens before the water reaches the end-users. USEPA mandates that the free chlorine level in drinking water should be 0.2mg/L to 4 mg/L. …

Revealing The Effects Of Climate Change And Fungicides On Soil Microbial Communities In The Lower Rio Grande Valley, Texas, Armida Rivera

Theses and Dissertations

Fungicide applications are effective to prevent fungal pathogens that are known to cause crop damage and decrease yields. However, these pesticides can exert toxic or inhibitory effects on non-targeted organisms such as soil microbial communities. In addition, it is unknown to what extent shifts in temperature and soil moisture resulting from global climate change, alter the activities of non-targeted soil organisms. The aim of this study was to evaluate soil biological parameters such as soil respiration and enzyme activities involved in the cycling of carbon, nitrogen, and phosphorous (Beta-glucosidase, Fluorescein Diacetate (FDA) Hydrolysis, urease, alkaline phosphatase, acid phosphatase, and N-acetyl-Beta-glucosaminidase) …

Financial Literacy And Consumer Well-Being: Examining The Role Of Gender Role Ideology, Lorena Garcia Ramon

Theses and Dissertations

Financial literacy, or the ability to process economic information and make informed decisions about financial planning, wealth accumulation, debt, and pensions, has been linked to beneficial financial behaviors that support financial well-being. Despite these benefits, consumers tend to underperform in financial literacy tests with women generally faring worse than men. This dissertation draws from gender roles literature and Expectancy-Value Theory to examine how, why, and when traditional attitudes regarding societal gender roles (i.e., gender role ideology) hinder women’s financial literacy and willingness to acquire financial knowledge. Moreover, it examines how financial literacy and willingness to …

Conspicuous Asceticism: Collapsing Consumers' Hungry Ghosts, Ash Zareian

Theses and Dissertations

The author investigates an emerging construct called conspicuous asceticism expositioned from a narcissism-centric view. The understanding of this construct is approached by drawing an idiomatic semantic parallel in opposition to conspicuous consumption and by utilizing its current theoretical framework of narcissism. Moreover, this paper seeks to extend conspicuous consumption’s theoretical framework as synonymous with the construct of compulsive consumption. Furthermore, I illustrate that consumers must transcend narcissism through engaging in treatment modalities requisite to operationalize a pioneering effort in which consumers can engage in marketing campaign efforts to advertise conspicuous ascetic contexts. This dissertation gleans from extant literature in sociology, …

Assessment Of Nitrogen-Based Fertilizer Transport And Microbial Activities In Sandy Soil Profiles In South Texas, Gladys De La Rosa

Theses and Dissertations

Conventional farming is a common practice in Lower Rio Grande Valley (LRGV) and the application of nitrogen fertilizer is essential for plant growth and support. However, managing the rate of nitrogen that is applied can benefit farmers financially and reduce nitrate leaching that can have an adverse effect on the local environment and aquatic systems, e.g., rivers and estuaries. Sandy soils are more vulnerable to water infiltration due to the large proportion of macropores. This study aims to (i) assess how nitrate from a variety of fertilizers (i.e., synthetic and organic) distributes on the top 60 cm layer of a …

Weaving Ethnic Identity: Discovering The Threads Of Multilingual Diversity In The Fabric Of Group Identity Among Karen Communities Of Denver, Colorado, Charity J. Seidler

Theses and Dissertations

How do Karen immigrants use language within Colorado communities? My thesis answers this question through narrative case studies of six S’gaw Karen women. Many Karen refugees, who flee the decades-long conflict within their homeland in Myanmar (Burma), find themselves navigating life first in Thailand, and eventually in the United States as foreign-language speakers. These refugees encounter numerous linguistic and cultural barriers in their new U.S. homeland, where it is difficult to function in many domains if they do not have the opportunity to learn much English upon arrival.

The six case studies are based on recorded sociolinguistic qualitative open interviews. …

Theses and Dissertations

Focal Structures are key sets of individuals who may be responsible for online socially minded events, protests, or leading citizen engagement efforts on social media networks. Discovering focal structure sets who able to promote online social campaigns is important, but complex, as they are typically active locally, globally, and acting unlike central users and influencers, focal structure sets can influence large social media networks. Researchers applied a greedy algorithm to discover focal structure sets in social media networks. However, the outcomes were lacking on the users’ activities and interests that made the analysis incomplete. In this research, I present a …

Is There A Relationship Between Religiosity And Infidelity? A Meta-Analysis, Meghan Maddock

Theses and Dissertations

Infidelity in romantic relationships is common and has been associated with relationship dissolution and strain on individuals. Most religions teach that infidelity is harmful, and some researchers have suggested that, in the aggregate, more religious people might be less likely to report infidelity. However, research has been mixed, with some studies finding that more religious people are less likely to report infidelity, other studies finding that more religious people are more likely to report infidelity, and other studies finding no relationship. To clarify seemingly contradictory findings, I conducted a meta-analysis of the infidelity-religiosity relationship with 38 studies and a total …

Dónde Están Les Latinxs? A Content Analysis Of Latinx Representation Across Three Clinical Disciplines, Haley M. Hinkle

Theses and Dissertations

Latinx, or Hispanic/Latino, minoritized groups experience a broad spectrum of mental health challenges, disparities, and risks at a disproportionate rate compared to both their non-White counterparts and compared to other minorized groups in the U.S. (SAMHSA, 2015). They also experience a number of cultural and individual strengths associated with their values, practices, and resiliencies (Leyva et al, 2022; Gennetian et al, 2021; Calzada et al, 2020). However, given the substantial percentage of Latinxs who live in the United States (18.7%), the mental health needs of this minoritized group are not sufficiently addressed in social science literature, as a number of …

The microbrewery industry has experienced exponential growth since 2005. As a result, the by-products associated with this industry are becoming increasingly available. One of these by-products is liquid brewers yeast, which is produced in excess during the production of beer. For livestock producers that have access to microbreweries, a potentially economical way to feed their flock would to be repurpose the by-product that would otherwise be disposed. Similarly, microbreweries would benefit from repurposing the liquid brewers yeast as livestock feed, resulting in less waste and a more sustainable beer production system.Researchers have evaluated the effect of liquid brewers yeast supplementation …

Adolescent Religious Identity And Body Esteem, Megan Gale

Theses and Dissertations

Adolescents experience a key developmental process of identity formation and try to understand who they are and how they feel about themselves. While research has found religiosity to often predict increased body esteem for religious adults, little is known about the association between religiosity and body esteem for adolescents. Using an Identity Theory lens, the current cross-sectional study (n=1,693) examined the relationship between adolescent religious identity (religious salience and belief being a child of God) and body esteem, mediated by one's attachment to God. Three structural equation mediation models examined 1) overall relationships; 2) relationships by gender; and 3) relationships …

Communication About Pornography And Relationship Quality In Different-Gender Couples, Rachel Ann Augustus

Theses and Dissertations

Scholars have begun to suggest factors that explain and influence the association between pornography use and relationship outcomes but further work is still needed. Communication about pornography is one variable that may be influential but it has yet to be considered in this way. Using a dyadic sample of 713 different-gender couples, I used Actor-Partner Structural Equation Modeling to analyze associations between pornography use (male pornography use, joint pornography use and female pornography use) and relational quality (from the perspective of each partner, respectively), associations between communication about pornography and relationship quality. Communication about pornography was also considered as a …

Participants were asked about friendship generally with the hope that information on the research questions would be …

Behavioral Indicators Of The Therapeutic Alliance In Relation To Dropout In Couple Therapy, S. Celeste Esplin

Theses and Dissertations

Almost half of those who start therapy drop out early (Thalmayer, 2018). When therapists work to improve the therapeutic alliance, clients are more likely to stay in treatment and chances of recovery improve (D'Aniello et al., 2018; Escudero & Friedlander, 2017). However, the existing research comes almost entirely from client self-reports of the alliance. Little research has examined what occurs during the session. There has been no research to determine what specific therapeutic alliance behaviors are related to early termination. The current naturalistic study sought to discover if behaviors that strengthen or diminish the therapeutic alliance are related to early …

Exercise As A Predictor Of Change In Self-Reported Marital Satisfaction And Behaviors Of Couples In Therapy, Emily J. Nelson

Theses and Dissertations

Recent studies looking to link physical exercise with beneficial couple outcomes have had mixed results, showing benefits for females but not males in some instances, and even negative effects for males in one instance. However, these studies used self-report data for exercise which may suffer from reporting errors. This study analyzed how daily exercise, measured by participants wearing accelerometers, impacts marital satisfaction, positive behaviors, and negative behaviors in a clinical population. The data was analyzed using multilevel models to determine how time spent exercising impacted individuals and their partners in terms of relationship outcomes. Results indicated small but significant relationships …

Ethanol-Induced Impacts On Nervous System Development And Dopamine Transporter Characterization In Schmidtea Mediterranea Planaria, Brennen Covely

Theses and Dissertations

Fetal alcohol spectrum disorders (FASD) are diagnosed in 2-5% of newborns, but the biology underlying FASD is poorly understood and challenging to study with existing model organisms. A new model for FASD research is Schmidtea mediterranea (Smed) planaria. Smed have a remarkable ability to regenerate their central nervous system (CNS), and possess a well-studied, simple genome. Previous studies have shown that ethanol exposure delays this regeneration, yet this relationship is not fully understood. Here, we show that alcohol exposure affects Smed in a dose-dependent manner, eliciting characteristic withdrawal-like behaviors and impacting cognitive function. Interestingly, prior exposure does not alter subsequent …

Individual, Child, And Socioeconomic Factors: Effects On Custody Litigation, Natalie Elizabeth Fischer

Theses and Dissertations

Given that the United States has one of the highest divorce rates in the world, it is imperative to determine affects it may have on the population, as well as associated events linked to the divorce process (Kennedy & Ruggles, 2014; Kreider & Fields, 2002). One such event is that of custody decisions in the divorcing family, as children’s time and placements need to be secured amidst the change. Although there are many different custody arrangement types, one of the most discussed is that of physical custody and how it is determined by courts. There are many variables considered by …
