The Economic Viability Of Cocoa Crop Insurance In Ghana, Justin D. Mckinley

Graduate Theses and Dissertations

This study was motivated by the fact that Ghanaian cocoa producers face lower yields than other main cocoa producing counties which in turn increases food insecurity for smallholder producers. In addition, low yields experienced by Ghanaian producers is a driving factor for forest degradation and deforestation as cocoa producers encroach further into previously undisturbed forests in efforts to increase their incomes. There are currently production methods to achieve higher yields readily available in Ghana; however, many producers choose not to adopt these methods because they are seen as too risky, or simply cannot adopt them due to financial/credit constraints. A …

Assessing Net Returns To Blueberry Production Using A Decision Support Tool, Sokha Sok

Graduate Theses and Dissertations

The purpose of this study was to develop and assess the profitability of four highbush blueberry farming systems in the south: organic field production, conventional field production, organic high tunnel production and conventional high tunnel production. Four baseline budget scenarios, one for each system, are developed for a 15 year production period. The results suggest that under expected production and price conditions for Northwest Arkansas, while all four production systems generated positive present value of net returns, the conventional field production produced the highest present value of net returns across the 15 years. The breakeven years of production were 7 …

European Consumers' Attitudes Towards Cisgenic Rice, Anne-Cécile Delwaide

Graduate Theses and Dissertations

The enhancement of existing plant breeding techniques, such as cisgenesis, allows plant breeders to enhance an existing cultivar quicker and with little to no genetic drag. Cisgenesis is the genetic modification of a recipient plant with natural gene(s) from a sexually compatible plant. Unlike transgenesis, which is the genetic modification of a recipient plant with gene(s) from any non‐plant organism, or from a donor plant that is sexually incompatible with the recipient plant, the results of cisgenesis could occur naturally over time. Currently, both cisgenic and transgenic products are classified as genetically modified organisms (GMOs) and are labeled as such …

Does Who We Are Influence What We Say? The Impact Of Organizational Identity On Responses To Ethical Issues, Amy J. Guerber

Graduate Theses and Dissertations

Business organizations frequently face ethical issues which may lead stakeholders to question the competence or integrity of organizational actors. In such cases, the way the organization communicates with its stakeholders can play a critical role in preserving or restoring organizational reputation, financial performance, and trust. Thus, understanding factors that influence organizational communication in the wake of ethical issues is important. Previous research has focused on the impact of situational characteristics on organizational responses and stakeholder reactions to those responses but has not explored the role that organizational characteristics play in shaping firms' responses to ethical issues.

The current study seeks …

Bystanders And Bullying: A Reflective Examination Of College Students' Experiences, Katherine Marie Larsen

Honors Theses

This study examines the individual responses of bystanders to bullying based on situational and personal variables. Using self-report data collected on 935 university students, these variables were used to determine if there was a relationship between the variables and the decision to intervene in a bullying situation for a friend. The results suggested that race, sexual orientation, and direct forms of bullying (physical and cyber bullying) have a relationship between an individual’s choice to intervene in a bullying situation for a friend. The findings failed to support the hypothesis that personal factors such as gender, socio-economic status, and a history …

America's Closet Door: An Investigation Of Television And Its Effects On Perceptions Of Homosexuality, Sara Moroni

This study investigates the relationship between television and social perceptions. It uses the television shows Will&Grace, The L Word, Queer as Folk, and Modern Family for rhetorical analysis. Then, it uses the information gained from the analysis to hypothesize how and why these television shows both reflect and affect social perceptions of homosexuality.

Using Greet To Analyze Natural Gas Usage In Municipal Fleets, Bradley E. Gibson

Honors Theses

GREET was used to calculate energy consumption and pollutants emitted from specific fuel/vehicle types when given a specific set of parameters. In this case, the parameters were the type of fuel mix from TVA, the selected vehicle year of 2015, the vehicle weight specified in the heavy-duty vehicle range, and type of simulation technique, which was the Hammersely Sequence Sampling. These inputs, along with seventeen fuel/vehicles mixes, specific pollutants, and cost considerations, were used to investigate the environmental impact of the transition from petrol diesel to natural gas in the municipal fleets of Chattanooga, Tennessee. The energy consumption included coal, …

Effects Of A Nutrition Education Intervention On Inner City Children, Stephanie P. Windle

Honors Theses

This paper focuses on nutrition education research conducted between February and April 2014. The researcher’s goal was to determine the effectiveness of a nutrition education intervention on low-income children. The USDA and Academy of Nutrition and Dietetics provided most of the research used to create the intervention. The definition of “healthy” used for this study was defined by the USDA (2014) as “whole foods such as fruits, vegetables, whole grains, fat free or low-fat dairy, and lean meats that are perishable (fresh, refrigerated, or frozen) or canned as well as nutrient-dense foods and beverages encouraged by the 2010 Dietary Guidelines …

The Eu's Cookie Cutter, But Not The Eu's Cookie, Sylvia Zdunek

Honors Theses

The members of the European Union have never had a common identity that has united them together beyond their geographical definition of "Europe." Since the beginning of the European Union and the introduction of the Euro, the decision makers of the Union have been pushing for a collective European identity. The need for this identity comes from the belief that in order for the Union to be economically sound, it needs an underlying homogenous culture. A unity in identity, values, and ideals is stronger than a unity based solely on a common currency as it lacks personal characteristics that people …

"I Wasn't Born A Boy – I Was Born A Baby": Best Practices Versus Accepted Practices In News Coverage Of The Transgender Community, Anna Hornell

Journalism

As transgender people and issues have gained prominence in American media over the past few years, more and more journalists find themselves covering a small and marginalized community that they may not have any previous experience with. Using standards set by LGBT media watchdog GLAAD, this study aimed to examine how the prevalence of problematic journalistic practices in covering the transgender community has (or has not) changed in recent years. A content analysis of 1,019 U.S. newspaper articles from 2009 and 2014 revealed some significant changes: almost all GLAAD-identified problematic practices that were studied appeared less commonly in 2014, although …

Beware: Teachers Who Blog, Charles J. Russo

Educational Leadership Faculty Publications

A recent case from Pennsylvania, Munroe v. Central Bucks School District (2014), raises fresh questions about the free speech and expression rights of public school teachers as they use the Internet. In Munroe, when a board terminated a high school teacher’s employment for making controversial postings about her students and colleagues on her personal blog—postings that proved disruptive—a federal trial court rejected the educator’s claim that she was dismissed in retaliation for exercising her right to free speech.

Before reviewing the facts and judicial opinion in Munroe, it is worth noting that blogs (a term coined in the late 1990s …

Abstract of Project

Shock Incarceration Programs Creative Problem Solving

Many women who are incarcerated inside correctional boot camp prisons might have substantial low self-esteem that could worsen due to the stress of the prison environment, confinement, and being far away from their children and family members. Shock Incarceration or “boot camp” male correctional programs are degrading for female inmates: They do not meet the special needs and problems of women. Programs are based on control theory, which implies that an individual’s behavior assimilates to that which is expected by society. Female inmates are taught discipline and responsibility by “breaking down …

IPEC Mini-grant application for funding of UNE student project Visual Voices: An Arts-Based Assessment Of The Perceived Identity Of Aging Maine Residents. This project was designed to investigate the topics of perception, identity, and aging. Between February and May 2015, over the course of twelve sessions, the UNE team met with six female residents of the Park Danforth senior living community in Portland to have conversations and create art about how the residents perceive themselves in contrast to how they feel perceived by important people in their lives, such as friends, family, and healthcare providers.

Assessing Pragmatic Language In Autism Spectrum Disorder: The Yale In Vivo Pragmatic Protocol, Elizabeth Schoen Simmons, Rhea Paul, Fred Volkmar

Communication Disorders Faculty Publications

Purpose: This study compared pragmatic language in youths (9–17 years) with autism spectrum disorder (ASD) and those with typical development (TD) on the Yale in vivo Pragmatic Protocol (YiPP), a semistructured, dynamic conversational assessment. Method: Participants (n = 118) were divided into groups based on age and diagnosis. Each completed the YiPP, which included 4 pragmatic domains (discourse management, communicative functions, conversational repair, presupposition). The participant’s response to each probe was scored correct or incorrect; incorrect scores elicited cues from the examiner, and level of cue required for a correction was also scored. Results: The YiPP showed high reliability and …

The Use Of Variable-Bagging And The Cross-Validation Selector In The Prediction Of Alzheimer’S Using The Adni Database., Michael Wayne Godbey

Electronic Theses and Dissertations

Dimensionality plays a huge part in the modeling process. If there are more elements in a data set than variables in each element then there are very few restrictions in selection of an algorithm. Bagging, bootstrap aggregating (Breiman, 1994), may also be used to improve a model’s prediction capability. On the other hand, if there more variables in each observation than the number of observations in the dataset, the number of usable algorithms is greatly reduced. The recently developed algorithm, support vector machines, was designed for such situations, in comparison to algorithms such as logistic regression which have instability issues …

Pathogenic Role Of Acrolein In Alcoholic Liver Disease., Wei-Yang (Jeremy) Chen

Electronic Theses and Dissertations

Alcohol is the most socially accepted addictive drug, and it can cause alcoholic liver disease (ALD), which is a major cause of morbidity and mortality in the United States and worldwide. Animal and human studies demonstrate that chronic alcohol consumption causes a pro-oxidant environment in the liver and increases hepatic lipid peroxidation and the accumulation of by-products such as acrolein and 4-hydroxynonenal. Acrolein is the most reactive and toxic aldehyde generated through lipid peroxidation. Also, acrolein is a major component of cigarette smoke, and there is increasing evidence that smoking negatively impacts the incidence, severity, and clinical course of chronic …

Pathogenic Role Of Phosphodiesterase 4 (Pde4) In The Development Of Alcohol Induced Hepatic Steatosis., Diana Veronica Avila

Electronic Theses and Dissertations

Alcohol induced hepatic steatosis is a significant risk factor for progressive liver disease. Steatotic hepatocytes have increased sensitivity to injury produced by inflammatory cytokines, particularly TNF. Cyclic adenosine monophosphate (cAMP) has been shown to play a significant role in the regulation of both TNF production and lipid metabolism. However, the role of altered cAMP homeostasis in alcohol mediated hepatic steatosis and injury has not been studied. cAMP levels are tightly regulated by phosphodiesterase family of enzymes. Our recent work demonstrated that increased expression of hepatic PDE4, which specifically hydrolyzes and decreases cAMP levels, plays a pathogenic role in the development …

The Impact Of Inflammatory And Immune Response-Related Genetic Variants On Prostate Cancer Risk Among Men Of African Descent., Dominique Zilpha Jones

Electronic Theses and Dissertations

Background: In the U.S., prostate cancer (PCA) metastasis is associated with a 5-yr survival rate of 29% and disproportionately affects men of African descent. Single nucleotide polymorphisms (SNPs) may serve as genetic markers to identify individuals at high risk of developing PCA. Methods: We examined main and joint effects of 119 inflammatory and immune response-associated SNPs among men of African descent (535 controls, 279 cases) via logistic regression (LR) and entropy-based-multi-factor dimensionality reduction (MDR) modeling. Results: MDR yielded highly synergistic [(TLR10, TLR6 and IRF3), (TLR2, IRAK4), (IL1R2, IL10, IL10RA)] interaction …

Development Of A Power Monitoring And Control System To Provide Demand Side Management Of Electric Vehicle Charging Activity., Nicholas Francis Jewell

Electronic Theses and Dissertations

Due to the recent inflow of Electric Vehicles (EVs) to the automobile market, new concerns have risen with respect to the additional electrical load and the resultant effects on an overloaded electric grid. Either for convenience purposes or possibly necessity due to limited electric range on EVs, some EV owners may desire to charge their EV while at work in addition to charging at home. These forward-thinking daytime charging providers are typically Commercial and Industrial (C&I) electric ratepayers, or other large electric consumers which constitute the majority of businesses, shopping centers, academic campuses and manufacturing facilities. Increased electricity consumption due …

Lunasin Reduces The Melanoma Stem Cell Population In Vitro And Inhibits Tumor Proliferation In Vivo., Christopher Paul Shidal

Electronic Theses and Dissertations

Lunasin is a 44 amino acid peptide derived from the soybean seed that has been shown to have cancer chemopreventive and chemotherapeutic properties. In this study, we investigated the potential utility of lunasin as a chemotherapeutic in a melanoma model. Initial studies showed that lunasin has little activity against established melanoma cell lines in vitro using adherent culture methods; however, lunasin’s in vitro activity was significantly higher in non-adherent colony-forming assays in soft agar and oncosphere assays. These results led us to investigate whether lunasin selectively affects cancer initiating cells (CIC) that are known to be present in these melanoma …

Modulation Of The Ovarian Cancer Humoral Response By Tumor-Derived Exosomes., Carolyn Denise Roberson

Electronic Theses and Dissertations

The pathogenesis of epithelial ovarian cancer is complicated by its diagnosis during the latter stages of the disease resulting from lack of symptoms or from presence of symptoms that mimic other conditions. Because of the often fatal prognosis by the time of actual detection, efforts are being made to better understand the host immune response to ovarian cancer. In this study, the contributions of the humoral immune response were investigated by focusing on the role of tumor-derived exosomes and their ability to modulate humoral immune responses. First, ovarian cancer patient-derived free circulating antibodies were investigated for immunoreactivity to patient antigen. …

Against The Grain : The Challenges Of Black Discourse Within Intercollegiate Policy Debate., Tiffany Yvonne Dillard-Knox

Electronic Theses and Dissertations

This research uses the speech community model of analysis to illustrate how language is used to determine inclusion into and exclusion from Debate. This has been done by examining the use of four Black discourse types in Intercollegiate Policy Debate: signifying, call and response, tonal semantics, and narrative sequencing to show the ways in which current debate practices (un)intentionally exclude Blacks. Upon examination, one can see that there is educational value to the methods used by majority of the Black student population within Debate. In addition to being a tool of empowerment for this student population, these students can also …

The Use Of Surface Cytokines As Biomarkers In B Cell Mediated Autoimmune Diseases, Abby Jones Weldon

Loma Linda University Electronic Theses, Dissertations & Projects

RA and SLE are B cell-mediated autoimmune diseases dominated by autoantibodies that affect over 1.5 million Americans. Together RA and SLE contribute to over 29 billion in healthcare costs, therefore due to the high financial burden and physical toll of these diseases on the population, there is a critical need to effectively and efficiently diagnose and treat RA and SLE patients. The aim of our studies was to identify biomarkers and drug targets to improve the identification and treatment of RA and SLE patients. As discussed above, APRIL, BAFF and TSLP have been implicated in the pathogenesis of RA and …

The Effect Of Grapes In Mice With Alzheimer's Disease And Brain Injury, Nikita Mistry

Loma Linda University Electronic Theses, Dissertations & Projects

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder resulting in cognitive and memory deficits and deposits of amyloid beta (Aβ) in the cortex and hippocampus are thought to be significant contributors to the disease process. Increasing evidence suggests that foods rich in polyphenols, such as pomegranates and grapes, may have neuroprotective effects in both rodents and humans. Our previous research has shown that a pomegranate-enriched diet decreased Aβ plaque load and improved behavior in Tg2576 mice. In this study, we determined whether a grape-enriched diet altered Aβ neuropathology and TBI in PSAPP mice. Mice received either craniotomy or a moderate …

Modulation Of T Lymphocytes By Tumor-Released Survivin, Jessica Marie Jutzy

Loma Linda University Electronic Theses, Dissertations & Projects

The tumor microenvironment is an area of intense interaction between normal and malignant cells. Factors and cell types within this environment can play a crucial role in the progression or regression of the tumor. Of primary interest are tumor-infiltrating T lymphocytes, which have been shown to have a key role in modifying the dynamics of the tumor microenvironment to promote or prevent tumor growth. While there is much in vitro and in vivo evidence for a modification of the tumor infiltrating T cell population toward a pro-tumor environment, what induces these changes within the tumor microenvironment has remained elusive. Our …

The Effect Of Root Canal Cleansing On The Retention Of Glass Fiber-Reinforced Posts, Faisal Dhaifallah Al-Qarni

Loma Linda University Electronic Theses, Dissertations & Projects

Esthetic glass fiber-reinforced posts are being used more often. The most commonly reported complication associated with these posts is debonding. Dentine conditioning with solutions such as EDTA or MTAD results in removal of smear layer and might improve the retention of posts to root canal dentin. Therefore, the purpose of this study was to investigate the effect of cleansing the post space with MTAD or EDTA on the bond strength of glass fiber-reinforced posts, when cemented with self-adhesive resin cement. Forty-five (n=15) extracted human premolar teeth were sectioned at the cemento-enamel junction to obtain root length of fifteen millimeters. Endodontic …

Stereotypes About Healthcare Professionals, Emotions, And Mammography Compliance, Kayla M. Kinworthy

Loma Linda University Electronic Theses, Dissertations & Projects

Rates of mammography screening are particularly low for minority women, with only 42% of Latin American (Latino) women in the U.S. reporting having a mammogram in the last year as compared to 53% of non-Latino White (Anglo) women [1]. Minority patients are more likely to report negative healthcare encounters with their health professionals [2; 3], which may result in less favorable cultural stereotypes about healthcare professionals and more negative emotional reactions. Guided by Betancourt’s Integrative Model of Culture, Psychological Processes, and Health Behavior [4] and the Stereotype Content Model [5], the aim of the present research was to examine the …

Risk Factors For Substance Use In The American Indian/Alaska Native Community, Kelli Lewis Rugless

Loma Linda University Electronic Theses, Dissertations & Projects

Research has indicated that substance use is a significant problem in the American Indian/Alaska Native adolescent community. What is less understood are the risk and protective factors specific to this community. Using data available from the Communities That Care Youth Survey, we analyzed risk and protective factors for current (30-day) and lifetime use of smokeless tobacco, cigarettes, alcohol, marijuana, and alcohol in a sample of 5,912 AI/AN adolescents. Logistic regression analyses were used and our findings indicated that peer and family influences, as well as ease of access to alcohol and other drugs had the greatest overall impact on AI/AN …
