Biological And Abiotic Factors Influencing Cetacean Mass Strandings In The Northeastern United States, Octavia Williams

HCNSO Student Capstones

Marine mammal strandings are frequent occurrences along many coastal areas around the world. The significance of stranded cetaceans has been of interest since around 300 B.C. when philosophers, like Aristotle, pondered why marine mammals, including whales, dolphins and porpoise beach themselves; and famous authors, like Henry David Thoreau, whose fascination in mammal strandings lead him to write a book about these mass occurrences off the coast of Cape Cod. Numerous hypothetical theories have been developed to explain these mass stranding phenomena. Though the causes of mass strandings remain unresolved, recent investigations suggest contributing factors could include environmental elements. Less emphasis …

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 …

Exploring Literature For Conceptualisations Of Male Infertility: A Phenomenological Analysis, Sunu C. Thomas

The Qualitative Report

Fathering a child is an important aspect of the identity of a man as motherhood is for a woman. Male factor infertility is one reason for the inability to father a child and this can contribute to many issues for a man at a personal or societal level. Although male infertility is a major contributing factor for the overall infertility for couples, our understanding of it is minimal. The objective of this exercise is to describe the meanings that men attach to their inability to reproduce and the conceptualisations of male infertility. A phenomenological approach has been used to analyse …

Pathogen Transmission Techniques And Genotypic Resistance To Disease In The Threatened Coral, Acropora Cervicornis, Megan Bock

HCNSO Student Theses and Dissertations

Unprecedented population losses of the staghorn coral, Acropora cervicornis, since the 1970s have been attributed primarily to disease. Although a positive linear relationship between disease prevalence and increased water temperature has been described, the pathogen(s) causing disease and whether they are spread through the water or vectors is still poorly understood. Additionally, an increase in disease outbreaks and severity has provided an urgent need to identify natural genotypic resistance to disease in Caribbean acroporids. Studies to date have explored a variety of pathogen transmission methods, but prior to this study, there has been no examination of differences among common techniques. …

Identifying Disease-Resistant And Thermal-Tolerant Genotypes In The Threatened Staghorn Coral, Acropora Cervicornis, Morgan V. Hightshoe

HCNSO Student Theses and Dissertations

Since the 1970s, loss of herbivores, coral bleaching, pollution, and disease epidemics have reshaped the ecological framework of coral reefs. Staghorn coral, Acropora cervicornis, was a major reef-building scleractinian coral found throughout Florida and the Caribbean that experienced unprecedented population declines primarily due to disease and coral bleaching. These two stressors are coupled; the highest coral disease prevalence occurs after periods of thermal stress caused by increased sea surface temperature. Previous research documented three disease-resistant A. cervicornis genotypes in Panama, but it is unknown if disease-resistant genotypes exist in the Florida Keys. Thermal tolerance has been found to be …

The Balance Of Public And Private Benefits Determines Sensitivity To Catastrophic Population Collapse In A Microbial Volunteer’S Dilemma, Aimee Doiron, Rodrigo Muzquiz, Tom Abraham

Undergraduate Student Symposium

Cooperation plays important roles in bacteria, plant, animal, and human ecosystems. Cheaters, who garner public benefits without paying the associated costs, often outcompete cooperators. One mechanism of cooperation is the production of a public good. This seems evolutionarily unstable, because cooperation tends to decrease the fitness of the individual, while promoting the fitness of cheaters. However, cooperation can persist even in the presence of cheaters, as long as a private benefit is retained by the cooperator. While theoretical and experimental studies have examined the use of public goods in cooperation, research has yet to determine how the ratio of public …

Residential Proximity To Electronic Dance Music Nightclubs And Associations With Substance Use, Sexual Behaviors, And Related Problems, Mance E. Buttram, Maria E. Pagano, Steven P. Kurtz

CAHSS Faculty Articles

This study examines the association between proximity of place of residence to preferred nightclub and substance use, sexual risk behaviors, and related problems, among a sample of 498 young adult substance users in Miami who report regular nightclub participation. Hierarchal linear models and logistic regressions were constructed to examine the impact of residential proximity to preferred nightclub on risk behaviors. Compared with participants residing in closer proximity to their preferred nightclub, participants residing further away reported higher intensities of alcohol and cocaine use (p < .01), greater condomless vaginal sex frequencies (p < .001), and more substance dependence symptoms (p < .05). Conversely, participants residing in closer proximity to their preferred nightclub had higher likelihood of arrest history (p < .05) than participants residing further away. Results suggest that participants residing further from their preferred nightclubs may be more invested in the nightclub outing and, therefore, engage in more risk behaviors.

Impact Of An Exercise Program On Stress, Fatigue, And Quality Of Life For Individuals Living With Primary Immunodeficiency Disease, Kerri Sowers

Department of Physical Therapy Student Theses, Dissertations and Capstones

Background: There are over 300 Primary Immunodeficiency diseases (PID) that are a result of a genetic or idiopathic dysfunction of any aspect of the immune system. These conditions result in a higher frequency of infections, autoimmune conditions, or malignancies. Moderate intensity exercise is thought to help the immune system, while high intensity exercise may have a negative impact on immune function. The impact of exercise on individuals with an impaired immune system due to PID is not yet understood. Purpose: The purpose of this study was to investigate whether a low to moderate intensity exercise program would have an effect …

Assessing Beliefs, Attitudes, And Perceived Risks Of Hiv As Predictors Of Hiv Testing Behavior Among Seniors In The Coachella Valley, California, Gillian Sealy

Health Sciences Program Student Theses, Dissertations and Capstones

According to the Centers for Disease Control and Prevention (CDC) (2017), at the end of 2014, approximately 428,724 people 50 years or older were diagnosed and living with HIV in the United States. A contributing factor to the high incidence of HIV in this population is unknown HIV/AIDS serostatus (Fenton, 2007). The U.S. Department of Health and Human Services (2018), terms serostatus as the state of having or not having detectable antibodies against a specific antigen (https://aidsinfo.nih.gov/understanding-hiv-aids/glossary/1632/serostatus). Contributing to the lack of knowledge about HIV serostatus, is that those over 50 are less likely to be tested for HIV even …

This study examined multifactorial risk factors and prevention mechanisms associated with coronary artery disease.

The applied dissertation is a systematic review of the literature designed to answer the question: What prevention strategies reduce multifactorial risk factors associated with the onset of coronary artery disease? The …

Emerging Hotspot Analysis Of Florida Manatee (Trichechus Manatus Latirostris) Mortality (1974-2012), Crystal Ann Bass

HCNSO Student Theses and Dissertations

The Florida manatee (Trichechus manatus latirostris) is a protected species that is vulnerable to both anthropogenic and natural causes of mortality. The ability of wildlife managers to oversee regulation of this species is based on available abundance estimates and mortality data. Using existing manatee mortality data collected by Florida Fish and Wildlife Conservation Commission (FWC) from 1974-2012, this study focuses on identifying significant spatial clusters of high values or “hotspots” of manatee mortality and the temporal patterns of these hotspots using the novel “emerging hotspot analysis” ArcGIS tool. The categories of manatee mortality included in this analysis were …

Contextualizing The Young Adult Female Breast Cancer Experience: Developmental, Psychosocial, And Interpersonal Influences, Cameron Froude, Sandra Rigazio-Digilio, Laura Donorfio, Keith Bellizzi

The Qualitative Report

Breast cancer is the most common cancer among American women (American Cancer Society [ACS], 2016b). Adolescents and young adults (AYAs) as a group have a worse prognosis when compared to older adults (e.g., Tichy, Lim, & Anders, 2013). Due to limited understanding of the biology of cancers for AYAs, inadequate representation of AYAs in clinical trials, and AYAs’ unique psychosocial healthcare needs, the prognosis for this group, as compared to older women, is comparatively poor. One step in addressing the survival gap for AYAs is to explore the developmental and psychosocial factors that shape their illness experiences. This qualitative study …

Methodological Approach To The Ex Vivo Expansion And Detection Of T. Cruzi-Specific T Cells From Chronic Chagas Disease Patients, Gonzalo R. Acevedo, Silvia A. Longhi, Alcinette Bunying, Nazila Sabri, Augusto Atienza, Maria P. Zago, Radleigh Santos, Valeria A. Judkowski, Clemencia Pinilla, Karina A. Gomez

Mathematics Faculty Articles

The discovery of T cell epitopes is essential not only for gaining knowledge about host response to infectious disease but also for the development of immune-intervention strategies. In Chagas disease, given the size and complexity of the Trypanosoma cruzi proteome and its interaction with the host’s immune system, the fine specificity of T cells has not been extensively studied yet, and this is particularly true for the CD4+ T cell compartment. The aim of the present work was to optimize a protocol for the generation of parasite-specific memory T cell lines, representative of their in vivo precursor populations and capable …

A Consensus Definitive Classification Of Scavenger Receptors And Their Roles In Health And Disease, Mercy R Prabhudas, Cynthia L Baldwin, Paul L Bollyky, Dawn M E Bowdish, Kurt Drickamer, Maria Febbraio, Joachim Herz, Lester Kobzik, Monty Krieger, John Loike, Benita Mcvicker, Terry K Means, Soren K Moestrup, Steven R Post, Tatsuya Sawamura, Samuel Silverstein, Robert Charles Speth, Janice C Telfer, Geoffrey M Thiele, Xiang-Yang Wang, Samuel D Wright, Joseph El Khoury

Faculty Articles

Scavenger receptors constitute a large family of proteins that are structurally diverse and participate in a wide range of biological functions. These receptors are expressed predominantly by myeloid cells and recognize a diverse variety of ligands including endogenous and modified host-derived molecules and microbial pathogens. There are currently eight classes of scavenger receptors, many of which have multiple names, leading to inconsistencies and confusion in the literature. To address this problem, a workshop was organized by the United States National Institute of Allergy and Infectious Diseases, National Institutes of Health, to help develop a clear definition of scavenger receptors and …

Meaning Of Pregnancy Terms Among African-American Women, Stephanie Solomon, Sandra G. Suther, Ivette Lopez, Alicestine Ashford, Linda C. Amankwaa, Gareth Dutton

The Qualitative Report

The concept of pregnancy intendedness is complex and may not bear the same meaning to all women. Moreover, researcher definition and women’s meaning were thought to be different. Some researchers have indicated that it is unclear how well women understand and relate to questions used by the National Survey of Family Growth (NSFG) and how the classifications relate to women’s lives. The purpose of this study was to explore the meaning of terms such as planned and/or intended pregnancy among African-American women of childbearing age using a qualitative exploratory descriptive method. Although African-American women want children, they are three times …

Cooperation And Competition Shape Ecological Resistance During Periodic Spatial Disturbance Of Engineered Bacteria, Cortney E. Wilson, Allison J. Lopatkin, Travis J. A. Craddock, William W. Driscoll, Omar T. Eldakar, Jose V. Lopez, Robert P. Smith

Biology Faculty Articles

Cooperation is fundamental to the survival of many bacterial species. Previous studies have shown that spatial structure can both promote and suppress cooperation. Most environments where bacteria are found are periodically disturbed, which can affect the spatial structure of the population. Despite the important role that spatial disturbances play in maintaining ecological relationships, it remains unclear as to how periodic spatial disturbances affect bacteria dependent on cooperation for survival. Here, we use bacteria engineered with a strong Allee effect to investigate how the frequency of periodic spatial disturbances affects cooperation. We show that at intermediate frequencies of spatial disturbance, the …

Analysis Of Marital Expectations In African Immigrant And United States-Born Married Couples, Evadne Ngazimbi, Andrew P. Daire, Ryan G. Carlson, Matthew D. Munyon

The Qualitative Report

The current phenomenological qualitative study aimed to understand marital expectations in married African immigrants and United States-born (U.S.-born) married couples. Eighty-five African-born immigrant and U.S.-born couples from a predominately Seventh-day Adventist sample residing in the U.S. completed the Marital Expectations Questionnaire (MEQ). We analyzed data collected in response to the first question. Data analysis revealed 12 codes associated with four themes related to marital expectations: (a) Care and Support; (b) Love and affection (c) Commitment and (d) Shared Values. We present implications for marital relationships and future research.

Frustrations, Fights, And Friendships: The Physical, Emotional, And Behavioural Effects Of High-Density Crowding On Mumbai’S Suburban Rail Passengers, Lily Hirsch, Kirrilly Thompson, Danielle Every

The Qualitative Report

Crammed together in tight folds of humanity, the suburban rail passengers of Mumbai, India, experience the most densely crowded trains in the world (Basu & Hunt, 2012). Whilst the immediate physical descriptors of crowdedness in Mumbai are well understood (Hirsch, 2016), there is little knowledge of the effect this has on the multitude of passengers. This is an important omission, as the effects of crowding on passengers impact their attitudes, travel behavior, and travel decisions. This paper therefore seeks to discern the physical, emotional, and behavioural effects of rail passenger crowding in Mumbai, India. To achieve this, a qualitative methodology, …

The Assessment Of Burnout And Resilience In Correctional Officers, Vera A. Klinoff

Theses and Dissertations

Correctional Officers are responsible for responding to emergency/crisis situations in correctional settings. Research shows that their work is characterized by numerous psychological stressors that vary by degree and intensity, which can lead to compromised job performance and, ultimately, job burnout. Despite the increased attention directed to the problem of occupational stress in first responders among other professions over the past several years, virtually no investigations have focused on correctional officer resilience. The purpose of this study was to: (a) identify whether select positive personal variables (i.e., hope, optimism, social support) are associated with increased resilience, (b) determine the extent to …
