Fear Of The Future: A Sociological Profile Of Anxiety In College, Lauren Hannah

Renée Crown University Honors Thesis Projects - All

College students are currently experiencing what psychologists and media outlets refer to as an "anxiety epidemic." Undergraduates are self-reporting and seeking counseling for anxiety in record numbers. Fear of the Future: A Profile of Anxiety in College is an exploratory sociology project whose aim is to understand the experience, manifestations, and root causes of anxiety in late Millennial college students. The core research involves a survey of over 400 Syracuse University undergraduates and three interviews with some of Syracuse University's professional counselors. The demographic findings of the survey and the common threads among statements from counselors are synthesized to …

Income Inequality And Its Effect On Work-Related Fatalities, Luke Chadwick

Renée Crown University Honors Thesis Projects - All

While many papers have examined the effect of income inequality on a range of health outcomes, few have examined data on workplace fatalities. This study compiles data from the Bureau of Labor Statistics and Gini coefficient estimates for each of the U.S. states from 2008-2015 to estimate the effect of income inequality on workplace fatality rates using multiple regression models. The resulting estimates are partially significant; however, they do not conclusively demonstrate a causal relationship between income inequality and workplace fatalities due to biases and other factors.

Evaluating In Situ Grazing Patterns Of Lytechinus Variegatus And Their Effects On Seagrass Beds Of Thalassia Testudinum, Adrianna Parson

Master of Science in Integrative Biology Theses

The sea urchin Lytechinus variegatus is a known grazer of the seagrass Thalassia testudinum, and has been known to denude vast stands of seagrass beds at high densities. Outside of these denudation events, the effects of sea urchins on seagrass are poorly understood. This study examines the effects of L. variegatus on T. testudinum in situ, to understand how sea urchins are affecting seagrasses in situ. Results indicate that urchins were found in the offshore portion of the seagrass bed at densities up to 4 urchins/m². Changes in temperature and sediment size in the bay indicate …

Combining Translational And Functional Genomic Approaches To Augment Management Strategies Of Plant Parasitic Nematodes, Sandeep Sharma Khatiwada

Graduate Theses and Dissertations

Plant-parasitic nematodes pose a major threat to crop yield worldwide. Discontinued use of harmful chemicals has prompted the search for alternative management strategies that are effective yet environmentally friendly. Harpin proteins, which are derived from bacteria, and nematophagous fungi, natural predators of nematodes, are ideal for biological control of plant-parasitic nematodes. However, research on the efficacy of harpin proteins on nematodes, and biology of nematophagous fungi is minimal. Previously, a taxonomically uncharacterized nematophagous fungus designated ARF18 effectively suppressed nematode populations in soil. The overarching goal of this dissertation is to utilize applied and functional genomic approaches to augment management of …

A Meat Paradox: Media's Role In Mitigating The Omnivore's Dilemma, Karyn Camille Lewis

Master's Theses

The purpose of this research is to identify and understand media’s role in meat consumption and a disassociation of meat and its animal of origin. This study questions consumer behavior based on media portrayals of meat products as well as how consumers perceive these portrayals, meat consumption patterns based on media and family influence, and the types and levels of satisfaction (ex: self-esteem or masculinity) consumers receive from meat products.

A quantitative research approach was proposed for this study. The primary research method was a survey among students, faculty and staff at The University of Southern Mississippi. A total of …

Impact Of Prolonged Sitting On Cognitive Function: Implications For Cardio-Metabolic Risk, Sabina Miller

Master's Theses

Purpose: To determine if prolonged sitting negatively impacts cognitive function, cerebral perfusion, and central cardiovascular hemodynamics; and secondly, to test whether weight or physical activity status alters this response. Methods: Participants (N=20, age=26±7; BMI=30±7 kg/m²; 7 female) were taken through 3 hrs of sitting followed by a 10-min walk (treadmill). Cognitive function was assessed during sitting (10, 60, 120, and 180 mins) and following the walk using a color/word Stroop test. Cerebral perfusion was measured via near infrared spectroscopy (total hemoglobin—tHb). Central cardiovascular hemodynamics and aortic stiffness (pulse wave velocity—PWV) were measured using the SphygmoCor XCEL device before, …

Parental Care, Offspring Abandonment, And Filial Cannibalism, Mackenzie Davenport

Honors Theses

Parental care is a fundamental life-history trait that is found in many animals (reviewed in Royle et al. 2012). Parental care can include behaviors such as egg cleaning (Knouft et al. 2003), egg guarding (Royle et al. 2012, pg. 4), egg provisioning (Simmons & Parker 1989; Hilker & Meiners 2002; Royle et al. 2012, pg. 2), and oviposition-site selection (Refsnider & Janzen 2010). Such forms of parental care typically result in the spatial clumping of parents and their offspring. This often leads to density effects on within-clutch egg mortality, meaning that when within-clutch egg density increases, egg mortality also increases. …

Changes In Ant Biodiversity Across An Urban Gradient, Hao Brooks

Honors Theses

There are two aims to this study: compare diversity across an urban gradient and across seasons. We deployed traps and identified the collected 12 ant species at nine different sites centered at Chattanooga, Tennessee, for the purpose of relating levels of urbanization to the diversity of ant species at each site. We successfully sampled in the summer (June 27, 2017) and spring (March 31, 2018), and unsuccessfully sampled in winter (Feb. 16, 2018) when we collected zero ants, likely due to cold soil temperatures. To quantify “urbanization” we divided the sites into “Urban” core verses surrounding “Suburban” area using a …

Optimizing High-Speed Exercise Performance : Effect Of Load., Ling Bai

Electronic Theses and Dissertations

The purpose of this study was to identify an optimal load for the knee extension exercise done with Impulse (Newnan, GA). Forty-one women and twenty-nine men made six laboratory visits, including two familiarization sessions of the knee extension exercise and four real workout sessions which entailed four 30-second exercise sets, separated by 120-second rests, against four different loads (0Kg, 3.41Kg, 5.68Kg, 7.95Kg). A Latin Squares design was used to counterbalance the sequence of the sets. Average force (AF), peak force (PF), total work (TW), Impulse value, and the number of knee extension repetitions were each analyzed with a 2 (gender) …

A Model To Study The Effects Of Whole Life Chronic Exposure To Arsenic Or Cadmium On The Development Of Adult Metabolic Syndrome : Initial Characterization Of Hepatic Changes., Jamie L. Young

Electronic Theses and Dissertations

Metabolic syndrome (MetS) is a group of diseases affecting < 30% of adults. Although obesity is a major risk for the development of MetS, it does not account for all cases, suggesting contribution of other risk factors. We hypothesized that early life exposure to arsenic (As) or cadmium (Cd) may represent such a risk. The purpose of this study was to characterize a model to discern the effects of early life exposures to Cd and As on high fat diet (HFD)-induced MetS. Adult C57BL/6J mice were exposed to control or metals containing drinking water. Pregnant dams and offspring were continuously exposed to the same toxicants as their parents. At weaning, offspring were fed LFD or HFD and sacrificed 10 or 24 weeks later. Metal exposure caused time- and sex-dependent alterations in HFD-induced variables of liver damage. The initial results suggest that these toxicants enhanced obesity-induced liver injury.

Periodontitis In Patients With Type 2 Diabetes Mellitus, Simran Agarwal, Deepthi Gangaram, Mir Saleem

Biology Faculty Articles

Periodontitis is a chronic, inflammatory disease that is characterized by swollen gums, degradation of jaw structure, and potentially tooth loss. Like Periodontitis, Type 2 Diabetes Mellitus is also highly prevalent and largely multifactorial. Type 2 Diabetes is a condition in which higher than normal blood glucose levels cannot be properly maintained as the body’s normal mechanism of maintaining proper blood glucose levels, the release of insulin from pancreatic islet β-cells, becomes ineffective. The purpose of this literature review is to explore the relationship between the incidences of Periodontitis and Type 2 Diabetes. The risk that Type 2 Diabetes poses for …

A Cross-Training Program Does Not Alter Self-Reported Physical Activity Levels In Elementary School Children, Melody L. White, Matthew S. Renfrow, Richards S. Farley, Dana K. Fuller, Brandi M. Eveland-Sayers, Jennifer L. Caputo

ETSU Faculty Works

The purpose of the study was to examine the effects of a school-based cross-training program on body mass index (BMI), attitudes toward physical activity (ATPA), and physical activity (PA) levels of children in the 4^th and 5^th grades. Children (N = 118) were divided into control (n = 60) and experimental (n = 58) groups based on class availability. While the control group continued academic classes as usual, the experimental group participated in cross-training involving resistance training (RT), calisthenics, and stretching twice a week for 10 weeks. Pre- and post-intervention measures included height, mass, ATPA, and PA. BMI …

A Study Into The Relationship Between Nutrition And Income In A College Setting, Alyssa Hicks

Economics Undergraduate Honors Theses

Many health related issues in the United States are linked to Americans’ poor diet choices. College students, a subset of that population, establish important trends in their diet habits that they will maintain over their four years in college and beyond. Although previous literature has found income to be a determinant of diet, this paper does not find income to be a significant predictor of student nutrition. One potential explanation is that college provides a unique environment and circumstance. Yet, additional income suggests it could be important for students who suffer from a lack of funds—increasing their income brings about …

Consumers’ Willingness To Pay For Hydroponic Lettuce, Daniel Gilmour

Graduate Theses and Dissertations

With continued advances in hydroponic plant production technology, an increasing number of farms have begun using hydroponic techniques to grow leaf lettuce and other food crops in a controlled environment. Recent controversy about the ongoing inclusion of hydroponics in the USDA organic program has highlighted uncertainty about marketing for hydroponic crops. In November 2017, the National Organic Standards Board voted not to recommend that hydroponic farms be banned from applying for organic certification. Since then, continued controversy has led a group of organic producers to start an additional independent certification program that would exclude hydroponic crops. While hydroponic production may …

Body Image, Fear Of Fat, And Attentional Bias For Thin And Non-Thin Bodies, Neusha Khaleghi

Electronic Theses and Dissertations

The study examined the impact of Attentional Bias Modification (ABM) on body image and fear of fat in college women. Participants were randomly assigned to one of two conditions: an ABM condition or a non-ABM placebo condition in viewing a series of thin and non-thin body stimuli. Extending previous work documenting associations between attentional biases and body dissatisfaction and the effects of ABM on body dissatisfaction, we hypothesized that effects of an ABM task designed to direct attention toward non-thin bodies would: (a) decrease body dissatisfaction, (b) increase body appreciation, and (c) decrease fear of fat. There were no significant …

Changes In The Microbial Community Of Lubomirskia Baicalensis Affected By Red Sponge Disease, Colin Rorex

Electronic Theses and Dissertations

Lake Baikal is the oldest known lake and a unique ecosystem, home to several species of fresh water sponge. A disease outbreak affecting the dominant species, Lubormirskia baialensis, was recently reported. The cause of the disease has not been determined but one of the current hypothesis is that the increase in methane concentration is correlated to the disease outbreak. This pilot study characterized the microbiomes of sick and healthy sponges through the use of 16S rRNA sequencing. Sick sponge microbiomes shared a conserved group of taxa while the healthy sponge microbiomes had greater diversity. Indicator species analysis identified two significant …

Intestinal Permeability And Microbial Dysbiosis In Acute Coronary Syndrome (Miacs Study), Tarik Z. Alhmoud

Biomedical Sciences ETDs

Background: Acute Coronary Syndrome (ACS) is a leading cause of morbidity and mortality. Metabolic syndrome and obesity are major risk factors for atherosclerosis and ACS. Dysbiosis plays an important role in metabolic syndrome and obesity. Studies show a markedly increased risk of heart attacks in patients with high levels of the pro-atherogenic metabolite trimethylamine-N-Oxide (TMAO). TMAO is produced by the intestinal microbial flora through metabolism of dietary phospholipids; Gram-negative bacteria (Phylum Proteobacteria) is the major source of TMAO metabolism. Patients with obesity and metabolic syndrome have a defective intestinal tight-junctional (TJ) barrier, which allows paracellular permeation of luminal antigens such …

Replacing Herbicides With Groundcovers To Enhance Vineyard Sustainability, Benjamin A. Loseke

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

In many Midwestern vineyards a three to four-foot weed-free strip is maintained directly beneath the vines to reduce vine-weed competition. Conventionally, this strip has been conserved with repeated applications of herbicide, mainly glyphosate. The necessity for this weed-free strip to reduce vine-weed competition has been well documented in more arid climates. However, in areas with higher soil fertility and adequate rainfall, this strip may be unnecessary. Moreover, stand establishment and early vine growth have not been well documented when planting groundcovers (GC) immediately following the vine planting. The main objective of this project is to assess the severity of competition …

Informing Consent: Medical Malpractice And The Criminalization Of Pregnancy, Laura Beth Cohen

Michigan Law Review

Since the early 1990s, jurisdictions around the country have been using civil child abuse laws to penalize women for using illicit drugs during their pregnancies. Using civil child abuse laws in this way infringes on pregnant women’s civil rights and deters them from seeking prenatal care. Child Protective Services agencies are key players in this system. Women often become entangled with the Child Protective Services system through their health care providers. Providers will drug test pregnant women without first alerting them to the potential negative consequences stemming from a positive drug test. Doing so is a breach of these providers’ …

An Investigation Of The Impact Of Family Dynamics On Obesity Among African American Adolescent Girls, Tina Mcdyess

Dissertations

Children who are overweight and obese are more likely to maintain their weight status into adulthood (Fletcher, Cooper, Helms, Northington, & Winters, 2009; World Health Organization [WHO], 2015). The prevalence of obesity has shown a more consistent increase among African Americans aged 2-19 (Flegal, Carroll, Kit, & Ogden, 2012; Ogden, Carroll, Kit, & Flegal, 2012; Ogden, Carroll, Kit & Flegal, 2014) with an even greater disparity among African American girls (Ogden & Carroll, 2010). Family dynamics is one of the many factors of the environment that has been linked to obesity among children and adolescents. The purpose of this study …

Effects Of Starch-Entrapped Microsphere Supplementation On Metabolic Phenotype In C57bl/6j Mice, Sean Mcnabney

Open Access Theses

Resistant starches are complexes of amylose and/or amylopectin that are indigestible or only partially digestible in the small intestine. When these starches enter the colon, they undergo fermentation via resident bacterial strains to produce the short-chain fatty acids acetate, propionate, and butyrate. Not only does butyrate act as an energy source for colonocytes and regulate luminal pH, but butyrate supplementation has also been demonstrated to confer anti-inflammatory and chemopreventive benefits in cell culture models. Moreover, in murine models of diet-induced obesity and insulin resistance, dietary supplementation of sodium butyrate attenuated weight gain, reduced adipose tissue accumulation, and maintained insulin sensitivity …

Enamel Hypoplasia And Its Relation To Ethnicity And Socioeconomic Status In The 19th Century United States, Amanda Drew Olivas Cook

Undergraduate Honors Capstone Projects

Linear enamel hypoplasia (LEH) is a condition of tooth enamel characterized by linear bands in tooth enamel that result from metabolic stress during the childhood years of enamel formation. The presence of LEH has frequently been used in biological anthropology as a marker of stress experienced during childhood. This paper uses a biocultural approach to investigate the occurrence and severity of LEH defects on the teeth of African American and European American adult male remains in the Terry Anatomical Skeletal Collection. The Terry Collection consists of low socioeconomic status individuals whose remains were unclaimed at St. Louis morgues and hospitals, …

Student Moves: A Mixed Methods Cross- Sectional Study Of Elementary School- Based Physical Education In Omaha Public Schools, Ashley Carroll

Capstone Experience: Master of Public Health

Childhood obesity is one of the leading pediatric health problems and a major concern among Omaha metro parents (Professional Research Consultants, 2015). While there are many inter-related factors that contribute to the development of obesity, physical inactivity is a prominent risk factor. Targeting physical activity in health promotion is desirable for its feasibility and effectiveness in balancing energy consumption and expenditure (Hill, 2012). The Student Moves research project sought to inform school district and community strategies for promoting youth physical activity by assessing current physical education practices among a random sample of third- grade students in Omaha Public Schools. Variables …
