Individual Differences In Trust Toward Robotic Assistants, Tracy Sanders

Electronic Theses and Dissertations

This work on trust in human-robot interaction describes a series of three experiments from which a series of predictive models are developed. Previous work in trust and robotics has examined HRI components related to robots extensively, but there has been little research to quantify the influence of individual differences in trust on HRI. The present work seeks to fill that void by measuring individual differences across a variety of conditions, including differences in robot characteristics and environments. The models produced indicate that the main individual factors predicting trust in robotics include pre-existing attitudes towards robots, interpersonal trust, and personality traits.

The Mauc Gene Encodes A Versatile Signal Sequence And Redox Protein That Can Be Utilized In Native And Non-Native Protein Expression And Electron Trnasfer Systems, Brian Dow

Electronic Theses and Dissertations

The redox-active type 1 copper site of amicyanin is composed of a single copper ion that is coordinated by two histidines, a methionine, and a cysteine residue. This redox site has a potential of +265 mV at pH7.5. Over ten angstroms away from the copper site resides a tryptophan residue whose fluorescence is quenched by the copper. The effects of the tryptophan on the electron transfer (ET) properties were investigated by site-directed mutagenesis. Lessons learned about the hydrogen bonding network of amicyanin from the aforementioned study were attempted to be used as a model to increase the stability of another …

Pyroglutamylated Amyloid Beta Peptides Enhance Non-Fibrillogenic Aggregation Of The Unmodified Peptide, Gregory Goldblatt

Electronic Theses and Dissertations

Alzheimer's disease (AD) is accompanied by abnormal extracellular deposition of amyloid b (Ab) peptide. This has led to the amyloid cascade hypothesis, causatively relating Ab with AD. While Ab deposits assume a fibrillar cross-b structure, prefibrillar oligomers of Ab have been identified as the main cytotoxic agents in AD. Pyroglutamylated amyloid beta (AbpE) peptides are N-terminally truncated and pyroglutamylated (at Glu3 or Glu11) Ab molecules that display enhanced cytotoxicity and represent up to 50% of total Ab in AD brains. AbpE significantly enhances the toxicity of unmodified Ab by an unknown mechanism. Although in situ Ab populations are heterogeneous, the …

Supporting Situation Awareness Through Robot-To-Human Information Exchanges Under Conditions Of Visuospatial Perspective Taking, Elizabeth Phillips

Electronic Theses and Dissertations

The future vision of military Soldier—robot teams is one in which Soldiers and robots work together to complete separate, but interdependent tasks that advance the goals of the mission. However, in the near term, robots will be limited in their ability to successfully perform tasks without, at least, occasional assistance from their human teammates. A need exists to design, in robots, mechanisms that can support human situation awareness (SA) regarding the operations of the robot, which humans can use to provide interventions in robot tasks. The purpose of the current study was to test the effects of information exchanges provided …

From The Yellow Peril To The Model Minority: An Experimental Survey Examining Racial Attitudes Towards Asian Americans, Jenny Nguyen

Electronic Theses and Dissertations

Attitudinal research continues to show a more liberal trend in racial attitudes of Whites towards Blacks across a spectrum of issues (i.e. interracial marriage, residential integration, etc.) leading some to believe that we are moving into a post-racial society. However, a growing body of research has brought into question this utopian post-racial assertion. While Whites express support for racial equality in principle, they vehemently oppose race-targeted policies aimed to address racial inequality. This principle-policy gap has been consistently associated with persistent racial resentment; thus, contradicting the notion that of a post-racial era. Existing attitudinal research is often limited to the …

Role Of Klf8-Cxcr4 Signaling In Breast Cancer Metastasis, Debarati Mukherjee

Electronic Theses and Dissertations

Krüppel-like factor 8 (KLF8) has been strongly implicated in breast cancer metastasis. However, the underlying mechanisms remain largely unknown. In this study we report a novel signaling from KLF8 to C-X-C cytokine receptor type 4 (CXCR4) in breast cancer. Overexpression of KLF8 in MCF-10A cells induced CXCR4 expression at both mRNA and protein levels. This induction was well correlated with increased Boyden chamber migration, matrigel invasion and transendothelial migration (TEM) of the cells towards the ligand CXCL12. On the other hand, knockdown of KLF8 in MDA-MB-231 cells reduced CXCR4 expression associated with decreased cell migration, invasion and TEM towards CXCL12. …

Resistance Exercise Elicits Selective Mobilization And Adhesion Characteristics Of Granulocytes And Monocyte Subsets, Adam Jajtner

Electronic Theses and Dissertations

Resistance exercise eliciting muscle damage results in an immune response, leading to increases in circulating cytokines, and immune cell mobilization. Classical monocytes respond to muscle damage, however, little is known about the intermediate or nonclassical monocyte response to resistance exercise. Moreover, the impact of polyphenol supplementation in conjunction with resistance exercise on the innate immune response is unknown. The purpose of this study was to examine the immune response following resistance exercise with (PPB) and without (PL) polyphenol supplementation. Thirty-nine untrained men were randomized into three groups: PPB (n=13, 21.8±2.5yrs, 171.2±5.5cm, 71.2±8.2kg), PL (n=15, 21.6±2.5yrs, 176.5±4.9cm, 84.0±15.7kg) or a control …

Though I Know The River Is Dry, Victoria Campbell

Electronic Theses and Dissertations

Though I Know the River is Dry is a place-oriented collection of short fiction. The included stories follow female protagonists as they struggle with identity, relationships, and place in the world. The women in these stories frequently grapple with the fear of being loved in the wrong way, often unearthing a deeper examination of what it means to be tethered to a person or a place, along with the ramifications of these ties. All tangentially related to the island of Martha's Vineyard, place serves as a grounding element in this collection, as well as an entity with which the women …

Kidron Road And Other Stories, Jason Molohon

Electronic Theses and Dissertations

Kidron Road and Other Stories is a collection of fiction that ranges from the soberly tragic to the magically real. The characters in each selection are molded by their choices, the choices of others, and the cruel whims of fate. I am fascinated by the way fatalism and free will intersect in the human experience. Therefore, my work often explores the paradoxical way lives are molded by past decisions while, at the same time, those decisions seem determined by outside forces.

Flying Under The Lidar: Relating Forest Structure To Bat Community Diversity, Anna Schneider Swanson

Electronic Theses and Dissertations

Bats are important to many ecological processes such as pollination, insect (and by proxy, disease) control, and seed dispersal and can be used to monitor ecosystem health. However, they are facing unprecedented extinction risks from habitat degradation as well as pressures from pathogens (e.g., white-nose syndrome) and wind turbines. LiDAR allows ecologists to measure structural variables of forested landscapes with increased precision and accuracy at broader spatial scales than previously possible. This study used airborne LiDAR to classify forest habitat/canopy structure at the Ordway-Swisher Biological Station (OSBS) in north central Florida. LiDAR data were acquired by the National Ecological Observatory …

Low Impact Development Analysis And Comparative Assessment Of Wet Detention Ponds With Floating Treatment Wetlands, Nicholas Hartshorn

Electronic Theses and Dissertations

The aim of this thesis is to examine, develop, and assess innovative best management practices (BMPs) in stormwater management for pollutant reduction, flood control, and environmental sustainability. Previous research has clearly shown that urban stormwater runoff quickly transports pathogens, metals, sediment, and chemical pollutants to receiving waterbodies, resulting in the degradation of receiving waters and disruption of ecological networks. In response to this growing concern, regulatory agencies, such as the Environmental Protection Agency (EPA) and the Florida Department of Environmental Protection (FDEP), have set forth regulations aimed at protecting and restoring waterbodies. These regulations include numeric nutrient criteria (NNC) and …

Could Dietary Peroxidized Lipids Provoke An Intestinal Inflammatory Response?, Mitsushita Doomra

Electronic Theses and Dissertations

Inflammatory Bowel Disease and Crohn's disease represent chronic intestinal inflammatory diseases. It is suspected that bacterial infection is one of the causes of gut inflammation. Studies from others as well as from our laboratory have indicated that peroxidized lipids and their decomposition products are pro-inflammatory. As we consume considerable amounts of dietary oxidized lipids (arising from deep frying of vegetable oils), we hypothesize that dietary peroxidized lipids may also lead to intestinal inflammation. To test this hypothesis, intestine from C57BL/6J mice were collected and used in this study. The intestinal epithelial tissue as well as intestinal lymphoid tissues [Peyer's Patches …

Nature Records Itself: Concepts Of Truth And Representation In Nature Film And Nature Television Shows, Rashaad Rosalle

Electronic Theses and Dissertations

With the advent of nature photography and film came new ways to understand and interpret the natural world. Prior to the 1910s these formats involved a more scientific and objective approach to recording nature. This aesthetic was abandoned in favor for narrative recreations and Hollywood structure after the 1930s. It is my belief that the dominant use of anthropomorphization, manipulations of setting and animal life, and rugged explorer motifs, all have lead to a loss of a more contemplative and meditative appreciation of nature within the Nature television and film format. It is my goal to explore through a series …

Generosity Creates Its Own Ripple Effect, Traci Evison

UCF Forum

Sometimes we see an inspirational snippet of film on YouTube, hear an NPR broadcast or listen to a Ted Talk that materializes into action at what seems to be a random point in the future.

Linguistic Relativity And Multilingualism, Nicholas M. Casorio

HIM 1990-2015

Over the last decade, linguistic relativity has seen a resurgence in research and discourse on thought, language, and culture. One particular facet of this research, multilingualism, has been relatively sparse in comparison to the wealth of research available focusing on individual languages and monolingual speakers. This study represents a preliminary investigation that enters this arena by focusing specifically on how speakers of English as a second language use English basic color terms in respect to monolingual speakers. This is done by using a modified methodology from the World Color Survey as a comparative model of a speaker’s division of colors. …

Drama Has Issues: A Brief Retrospective On The American Theatre Critic In New York From 1925 To Present, Teresa M. Kilzi

HIM 1990-2015

Theatre criticism has evolved with the advancement of technology and the decline of print journalism. As consumers are given increasing agency by which they can filter the news and reporting they read and occasionally replace it with their own, the idea that a sole voice on a certain topic brandishes more dominance over it than the masses of people involved in its creation and sustainment becomes progressively absurd. Conversely, however, readers rely on theatre critics to make theatergoing decisions for them explicitly because critics are supposed experts on the subject and their opinions are to be respected and observed accordingly. …

The Influence Of Gun Control Legislation On Rampage Shootings, Andrew D. Manor

HIM 1990-2015

The United States has experienced several mass shootings in the past few years. It has been averaging one shooting every week in 2015, and something must be done about it. This problem appears to be limited to the United States since several other nations have been able to minimize, and almost eliminate the number of mass shootings. By taking an analysis of the gun laws of the United States with those of Australia and Canada it can be concluded that some aspects of strict gun control can reduce the number of mass shootings. Further, the United States should look at …

The United States Could Use A Therapist General, Barry Mauer

UCF Forum

Lately I have been imagining the creation of a new office in the executive branch: a Therapist General to advise the president and the nation about psychological problems affecting American citizens, groups and institutions. The person assuming this role could issue an annual report about the state of the nation’s mental health, investigate and report on the likely psychological costs and benefits of proposed laws, and issue recommendations for therapies to improve the nation’s psychological health.

Medulla: A 2d Sidescrolling Platformer Game That Teaches Basic Brain Structure And Function, Joey R. Fanfarelli, Stephanie Vie

Faculty Scholarship and Creative Works

This article explores the design and instructional effectiveness of Medulla, an educational game meant to teach brain structure and function to undergraduate psychology students. Developed in the retro-style platformer genre, Medulla uses two-dimensional gameplay with pixel-based graphics to engage students in learning content related to the brain, information which is often pre-requisite to more rigorous psychological study. A pretest posttest design was used in an experiment assessing Medulla’s ability to teach psychology content. Results indicated content knowledge was significantly higher on the posttest than the pretest, with a large effect size. Medulla appears to be an effective learning tool. These …

The Risk Of Secondary Lymphedema Due To Procedures In The Affected Arm Post-Mastectomy: A Literature Review, Lindsay Perna

HIM 1990-2015

The risk for upper extremity lymphedema post-mastectomy in women surgically treated for breast cancer is a concern since it is often painful, aesthetically displeasing, and can increase the risk of infection. However, there is a paucity of data examining if diagnostic procedures performed in the ipsilateral arm post-mastectomy increases the risk of lymphedema. The purpose of this research is to examine the relationship between diagnostic procedures performed in the ipsilateral arm post-mastectomy and the occurrence of lymphedema with or without related complications. A systematic review of the literature was conducted from multiple, online databases available from 1992 through 2014, and …

The Performance Of Health? Motivations Behind University Students' Decisions To Wear Athletic Attire, Shannon Payne

HIM 1990-2015

"Athleisure" is a relatively new term to the American lexicon, a portmanteau used to describe athletic clothing used for leisure purposes. Recent studies show a disconnect between consumers' desire to purchase athletic attire and the percentage of Americans considered "active to a healthy level and beyond." While athletic wear sales skyrocket, reported levels of inactivity have slowly increased in recent years. These trends indicate a phenomenon in which consumers prioritize ownership of athletic wear over athletics. In this research, I set out to answer the following research questions: How do university students interpret and understand the purchase and wearing of …

Analysis Of A Health Occupations Education Model Of Integrated Academics, Karen E. Gable Ed.D., Beverly A. Ransdell B.A.

Journal of Health Occupations Education

The integration of academics and occupational education is a concept supported by the business community, vocational educators and state and federal policy makers. The 1990 Carl Perkins Amendments required federal moneys to be spent on progmms that integrate academic and vocational education course sequencing, so that students achieve both academic and occupational competencies (Section 235). This study analyzed the process and product of courses developed within a secondary Health Professions Center magnet program in Indiana against the elements of success as outlined by Statz and Gmbb (1991) and Pritz (1989).
