Not Woman Enough Harassment: Scale Development And An Integrated Model From Antecedent To Outcome, Amanda Wolcott

Electronic Theses and Dissertations

The rise of research on workplace mistreatment in the past twenty years can be attributed to the realization that workplace mistreatment is associated with a host of deleterious outcomes for both the individual targets of the mistreatment and the organizations in which they work. However, the extant literature is failing to capture the full range of sex-based mistreatment that people may experience through a tendency to focus solely on sexual harassment and sex discrimination, which are very specific types of behavior based on one's sex and gender stereotypes. In this dissertation, I introduce the construct of Not Woman Enough Harassment, …

Chaotification As A Means Of Broadband Vibration Energy Harvesting With Piezoelectric Materials, Daniel Geiyer

Electronic Theses and Dissertations

Computing advances and component miniaturization in circuits coupled with stagnating battery technology have fueled growth in the development of high efficiency energy harvesters. Vibration-to-electricity energy harvesting techniques have been investigated extensively for use in sensors embedded in structures or in hard-to-reach locations like turbomachinery, surgical implants, and GPS animal trackers. Piezoelectric materials are commonly used in harvesters as they possess the ability to convert strain energy directly into electrical energy and can work concurrently as actuators for damping applications. The prototypical harvesting system places two piezoelectric patches on both sides of the location of maximum strain on a cantilever beam. …

Flocks, Swarms, Crowds, And Societies: On The Scope And Limits Of Cognition, Zachariah A. Neemeh

Honors Undergraduate Theses

Traditionally, the concept of cognition has been tied to the brain or the nervous system. Recent work in various noncomputational cognitive sciences has enlarged the category of “cognitive phenomena” to include the organism and its environment, distributed cognition across networks of actors, and basic cellular functions. The meaning, scope, and limits of ‘cognition’ are no longer clear or well-defined. In order to properly delimit the purview of the cognitive sciences, there is a strong need for a clarification of the definition of cognition. This paper will consider the outer bounds of that definition. Not all cognitive behaviors of a given …

The Sociocultural Perception Of The African American Woman's Bodily Aesthetics: Investigated In The Works Venus, God Don't Like Ugly, And Their Eyes Were Watching God, Andrene Loiten

Honors Undergraduate Theses

Despite contemporary movements towards tolerance and appreciation of differing cultural entities within the United States, the normative standard of beauty serves as a pinnacle of division amongst women. The normative standard of beauty—implemented by the dominant race within the States—encourages discrimination in regards to the perception of African American female beauty. Although information exists identifying the original influence pertaining to the negative perception of African American female beauty, the reason for its continued perpetuation within the African American community remains ill defined. Effects of this standard amongst African Americans are psychological and physiological. The destruction of self-image and appreciation for …

Political Ecology Of Medicinal Plant Use In Rural Nepal: Globalization, Environmental Degradation, And Cultural Transformation, Emily Dovydaitis

Honors Undergraduate Theses

Prior to the advent of biomedicine, rural communities in Nepal relied on phytochemically active compounds in medicinal plants as their primary source of medicine; however, ethnobotanical practices have shifted over time due to economic, environmental, and sociocultural stimuli. Findings from 2016 fieldwork conducted in Dumrikharka, Nepal and Tutung, Nepal are compared to existing literature to describe the political ecology of medicinal plants in rural Nepal.

Anthropogenic climate change threatens individual plant species and ecosystem biodiversity. Globalized markets unabated by weak conservation programs place increasing demands on medicinal plants. As indigenous plants become overharvested and more difficult to access, Nepalis incorporate …

To Evaluate The Function Of The Oxytocin Receptor In The Context Of Ovarian Cancer Cell Microenvironment To Determine If Oxytocin Can Induce An Anti-Inflammatory Response, Benjamin I. Schachner

Honors Undergraduate Theses

The treatment of most cancers can still be considered inadequate despite the steady progress being made. A prime example of this issue is with epithelial ovarian cancers; this disease presents a significant issue, with a 5-year survival rate of 46% and a survival rate of 28% in patients that develop metastatic disease. Since ovarian cancer has such a high mortality rate, effective treatment modalities are necessary to prolong the quality of life after diagnosis. Psychosocial stress is related to the progression, proliferation, and migration in cancer patients, but the mechanisms of this relationship are not fully understood. The present in …

Prevalence Of Dental Pathology In A Juvenile Population From The Ancient Maya Site Of Altun Ha, Lindsey D. Lefebvre

Honors Undergraduate Theses

The present research seeks to assesses the presence and prevalence of two distinct dental pathologies: linear enamel hypoplasia and caries in an ancient Maya juvenile subsample from Altun Ha, Belize spanning the Preclassic (ca. 600 B.C.) through the Terminal Classic (ca. 900 A.D.) periods. Teeth offer a remarkable wealth of information about the human experience in the past. Developmental and post-eruption pathology can provide insight into cultural and evolutionary processes by illuminating social and biological factors such as diet, weaning, illness, and overall health that manifest in observable changes to the composition of teeth. In addition, growth and developmental stages …

The Role Of The Y-Chromosome In The Evolution Of Autosomally Coded Traits, Ian Kutch

Electronic Theses and Dissertations

Recent work indicates that the Y-chromosome of the fruit fly Drosophila melanogaster can influence gene regulation on the autosomes and X chromosome. This newly discovered function of the Y has the potential to dramatically shape the regulatory evolution of numerous genes that reside throughout the genome; even for genes that code for both male and female traits. Given that the mechanism underlying the Y-linked influence on gene expression in D. melanogaster appears to exist in other independently evolved heterogametic sex chromosomes, the evolutionary implications of Y-linked regulatory variation (YRV) deserves to be explored. These implications include the potential for Y-chromosomes …

The Role Of Accounts And Apologies In Mitigating Blame Toward Human And Machine Agents, Kimberly Stowers

Electronic Theses and Dissertations

Would you trust a machine to make life-or-death decisions about your health and safety? Machines today are capable of achieving much more than they could 30 years ago—and the same will be said for machines that exist 30 years from now. The rise of intelligence in machines has resulted in humans entrusting them with ever-increasing responsibility. With this has arisen the question of whether machines should be given equal responsibility to humans—or if humans will ever perceive machines as being accountable for such responsibility. For example, if an intelligent machine accidentally harms a person, should it be blamed for its …

Leadership And Subordinate Engagement: A Meta-Analytic Examination Of Its Mechanisms Using Self-Determination Theory, Henry Young

Electronic Theses and Dissertations

Although past research has suggested ineffective leadership to be the most common reason for low levels of employee engagement, little is known about the mediating mechanisms underlying this relationship. To address this gap in research, I tested a theoretical model based on Self-Determination Theory (SDT; Deci & Ryan, 2000) in which two focal mechanisms, leader-member exchange (LMX) and empowerment, functioned in sequential order to predict the relationship between Full Range Leadership and subordinate engagement. Results showed that transactional leadership had positive and negative indirect effects on engagement, suggesting that transactional leadership comprises a "double-edged sword" as a predictor of subordinate …

Local Transient Characterization Of Thermofluid Heat Transfer Coefficient At Solid-Liquid Nano-Interfaces, Mehrdad Mehrvand

Electronic Theses and Dissertations

The demands for increasingly smaller, more capable, and higher power density technologies in microelectronics, energy, or aerospace systems have heightened the need for new methods to manage and characterize extreme heat fluxes (EHF). Microscale liquid cooling techniques are viewed as a promising solution for removing heat from high heat flux (HHF) systems. However, there have been challenges in physical understanding and predicting local thermal transport at the interface of micro and nanoscale structures/devices due to ballistic effects and complex coupling of mass, momentum, and energy transport at the solid-liquid-vapor interfaces over multiple time and length scales. Moreover, it's challenging to …

Quality By Design Procedure For Continuous Pharmaceutical Manufacturing: An Integrated Flowsheet Model Approach, Ashley Vezina

Electronic Theses and Dissertations

Pharmaceutical manufacturing is crucial to global healthcare and requires a higher, more consistent level of quality than any other industry. Yet, the traditional pharmaceutical batch manufacturing has remained largely unchanged in the last fifty years due to high R&D costs, shorter patent durations, and regulatory uncertainty. This has led regulatory bodies to promote modernization of manufacturing process to continuous pharmaceutical manufacturing (CPM) by introducing new methodologies including quality by design, design space, and process analytical technology (PAT). This represents a shift away from the traditional pharmaceutical manufacturing way of thinking towards a risk based approach that promotes increased product and …

Scientific Transformations: A Philosophical And Historical Analysis Of Cosmology From Copernicus To Newton, Manuel-Albert Castillo

Electronic Theses and Dissertations

The purpose of this thesis is to show a transformation around the scientific revolution from the sixteenth to seventeenth centuries against a Whig approach in which it still lingers in the history of science. I find the transformations of modern science through the cosmological models of Nicholas Copernicus, Johannes Kepler, Galileo Galilei and Isaac Newton. Since of the enormous content, I shall only pay particular attention to Copernicus and Newton in which the emerging sciences transformed the cosmos on what Alexandre Koyré calls from a "closed world to infinite universe". As an interdisciplinary approach, I used the methods and inquiries …

Cafeteria Culture: An Anthropological Approach To Lunchtime In A Central Florida Elementary School, Emily Herrington

Electronic Theses and Dissertations

Public school cafeterias are used by nearly 51 million children (ages 4-17) in the United States every day. With over 40% of the approximately 73 million children (ages 0-17) participating in the National School Lunch Program (NSLP), public school lunches carry resounding nutritional, social, and educational significance for their consumers. This fact, coupled with frequent media attention to school lunch food, notwithstanding, a notable lack of social scientific engagement with both students' perspectives and NSLP operators persists. Divided into two studies, this research utilizes ethnographic methods to explore students' lunchtime experiences within a Central Florida public elementary school cafeteria. Both …

A Major Dna Double Strand Repair Pathway And Cancer-Associated Circulating Proteins Are Effecters Of Epigenetic Revision., Brittany Allen

Electronic Theses and Dissertations

DNA methylation is a vital epigenetic process that acts as a major control mechanism for gene expression. In addition to its essential role in many normal cellular processes, it is also implicated in a wide variety of disease states and processes including cancer. Along with genetic mutations, aberrant DNA methylation patterns, specifically the inappropriate DNA methylation or demethylation of CpG residues, may activate oncogenes or suppress tumor suppressor genes, respectively. These changes can generate or facilitate the progression of tumorigenesis and tend to accumulate throughout the development of cancer. Although they play such a major role in cancer and in …

Plasma Dynamics Of Laser Filaments, Danielle Reyes

Electronic Theses and Dissertations

Laser filamentation is a complex phenomenon occurring for pulses with peak power above a critical value. A filament is a dynamic self-guided structure characterized by several unique qualities, which include a beam with a high-intensity core surrounded by an energy reservoir, a weakly ionized plasma channel, and supercontinuum generation. Several of the proposed applications for filamentation utilize the plasma channel, such as for assisted electric discharge and microwave guiding. However, filament properties are highly influenced by the physical conditions under which they are formed. A host of studies have been conducted to further characterize filaments, but much work still remains …

"Yeah I'M A Girl. I Play Video Games.": Identity Work Of Collegiate Women Gamers, Emily Rosenbaum

Electronic Theses and Dissertations

Despite accounting for almost half of the game playing population, women gamers are an underrepresented and excluded group within the gaming culture, both in regards to the advertising and production of video games. Prior research suggests that male gamers exclude women from gaming activities, question their legitimacy within the community, and create hostile environments for women both virtually in-game and in physical gaming spaces. As such, women gamers can be understood to hold a marginalized status with the gaming community. The current study looks to examine how women define themselves as "gamers" while negotiating this marginalized status. By adopting an …

Computational Fluid Dynamics Study Of Thromboembolism As A Function Of Shunt Size And Placement In The Hybrid Norwood Palliative Treatment Of Hypoplastic Left Heart Syndrome, John Seligson

Electronic Theses and Dissertations

The Hybrid Norwood procedure has emerged as a promising alternative palliative first stage treatment for infants with Hypoplastic Left Heart Syndrome (HLHS). The procedure is done to provide necessary blood flow to the pulmonary and systemic regions of the body. The procedure can affect hemodynamic conditions to be pro-thrombotic, and thrombus particles can form and release from the vessel walls and enter the flow. Assuming these particles are formed and released from the shunt surface, a Computational Fluid Dynamics (CFD) model can be used to mimic the patient's vasculature geometry and predict the occurrence of embolization to the carotid or …
