A Multimodal Approach For Monitoring Driving Behavior And Emotions, Arash Tavakoli, Vahid Balali, Arsalan Heydarian

Mineta Transportation Institute

Studies have indicated that emotions can significantly be influenced by environmental factors; these factors can also significantly influence drivers’ emotional state and, accordingly, their driving behavior. Furthermore, as the demand for autonomous vehicles is expected to significantly increase within the next decade, a proper understanding of drivers’/passengers’ emotions, behavior, and preferences will be needed in order to create an acceptable level of trust with humans. This paper proposes a novel semi-automated approach for understanding the effect of environmental factors on drivers’ emotions and behavioral changes through a naturalistic driving study. This setup includes a frontal road and facial camera, a …

Participation In Sporting Activities As A Mechanism For Enhancing Science Instruction, Erin Roades

Dissertations

ABSTRACT

After students have taken years of science classes, they still believe science content is disconnected to the “real” world or to their lives. Teaching without attention to relevance results in decreased motivation for learning and negative attitudes toward science. An instructional method incorporating physical, sport-related activities was used to develop relevance and enhance achievement in science compared to typical/traditional science instructional methods. In the typical method, science lessons consisted of front-loading science content through direct instruction followed by a laboratory activity to confirm lesson content. The experimental teaching strategy used was “Relevance Integration for Teaching Science using Sports Exploration” …

Assessing The Temporal Organization Of Walking Variability: A Systematic Review And Consensus Guidelines On Detrended Fluctuation Analysis, Deepak K. Ravi, Vivien Marmelat, William R. Taylor, Karl M. Newell, Nicholas Stergiou, Navrag B. Singh

Journal Articles

Human physiological signals are inherently rhythmic and have a hallmark feature in that even distant intrasignal measurements are related to each other. This relationship is termed long-range correlation and has been recognized as an indicator of the optimal state of the observed physiological systems, among which the locomotor system. Loss of long-range correlations has been found as a result of aging as well as disease, which can be evaluated with detrended fluctuation analysis (DFA). Recently, DFA and the scaling exponent α have been employed for understanding the degeneration of temporal regulation of human walking biorhythms in, for example, Parkinson disease …

Natural Categorization: Electrophysiological Responses To Viewing Natural Versus Built Environments, Salif Mahamane, Nick Wan, Alexis Porter, Allison S. Hancock, Justin Campbell, M. S. Lyons, Kerry Jordan

Psychology Faculty Publications

Environments are unique in terms of structural composition and evoked human experience. Previous studies suggest that natural compared to built environments may increase positive emotions. Humans in natural environments also demonstrate greater performance on attention-based tasks. Few studies have investigated cortical mechanisms underlying these phenomena or probed these differences from a neural perspective. Using a temporally sensitive electrophysiological approach, we employ an event-related, implicit passive viewing task to demonstrate that in humans, a greater late positive potential (LPP) occurs with exposure to built than natural environments, resulting in a faster return of activation to pre-stimulus baseline levels when viewing natural …

Nurses And Needlesticks: Perceptions Of Stigma And Hiv Risk, Bethany Sharon Moore

USF Tampa Graduate Theses and Dissertations

Health-care providers (HCPs) are vulnerable to occupational health hazards, including dirty needle-stick injuries (DNSIs), which increase the risk for infection with HIV and other blood-borne pathogens. This study examines the perceptions of nurses and nurse practitioners who work in various health care settings regarding HIV-risk and DNSIs, in order to ascertain how these perceptions inform their decision-making regarding their health and nursing practice. I utilize a phenomenological approach to analyze the lived reality and embodiment of the DNSI experience by HCPs. The study explores the personal and institutional level factors that may influence the timely reporting and treatment of DNSIs, …

Development Of A 3d Computational Vocal Fold Model Optimization Tool, Austin C. Vaterlaus

Theses and Dissertations

One of the primary objectives of voice research is to better understand the biomechanics of voice production and how changes in properties of the vocal folds (VFs) affect voice ability and quality. Synthetic VF models provide a way to observe how changes in geometry and material property affect voice biomechanics. This thesis seeks to evaluate an approach of using a genetic algorithm to design synthetic VF models in three ways: first, through the development of a computationally cost-effective 3D vocal fold model; second, by creating and optimizing a variation of this model; and third, by validating the approach. To reduce …

Mechanisms Of Bak Activation In The Initiation Of Mitochondrial Apoptosis, Geetika Singh

Theses and Dissertations (ETD)

Mitochondrial apoptosis is crucial for normal mammalian development and adult homeostasis being regulated by B-Cell Lymphoma-2 (BCL-2) proteins. Deregulation of BCL-2 proteins form the basis for myriad of human pathologies including cancer and autoimmune diseases. Therefore, BCL-2 proteins are considered key therapeutic targets. BCL-2 homologous antagonist/killer (BAK) is an effector of outer mitochondrial membrane (OMM) pemeabilization or mitochondrial poration. Despite progress in understanding BAK-mediated mitochondrial poration, the underlying multi-step mechanism is not clearly defined. Here, we provide mechanistic details on the early steps in this process related to BAK activation, including transient direct activation and autoactivation. We demonstrate for the …

Comparing The Protective Effects Of Resveratrol, Curcumin, And Sulforaphane Against Doxorubicin-Mediated Inflammation In Macrophages, Haidy Amr Abdelfatah Saleh

Theses and Dissertations

Doxorubicin (DOX) anti-tumor activity is accompanied by severe side effects such as cardiotoxicity and cardiomyopathy. These side effects are hypothesized to be mediated through doxorubicin induced inflammation. The aim of the current study, therefore, was to compare the effect of three naturally derived compounds with anti-inflammatory effects namely, curcumin (CUR), resveratrol (RES) and sulforaphane (SFN) against doxorubicin-mediated inflammation through affecting TLR4 signaling pathway in the murine macrophage cell line RAW264.7 stimulated with Lipopolysaccharide/Interferon-gamma (LPS/IFN- γ). In present study, RAW264.7 cells were stimulated with LPS/IFN-γ at a concentration of 10 ng/10 U/mL in the absence and presence of DOX (0.1 µM) …

The Detrimental Side Effects Of Retinol : Beyond Beauty Products, Michelle W. Lee

University Honors Theses

In recent years, the beauty industry has profited off our culture’s growing vanity and shows no signs of stopping anytime soon. With no certified way to freeze age, many consumers turn to skincare and makeup products that implement retinol as a means to combat wrinkles, even out skin tone, and treat acne. In this meta-analysis, I explore the detrimental side effects of retinol. As consumers of beauty products get younger and younger, they are more susceptible to potential side effects due to their early ages starting the compounds and their prolonged use. Here I examine three potentially dangerous conditions caused …

The Freedom To Move: Dance/Movement Therapy And Survivors Of Trafficking - An Evolving Practice, Rebecca Richardson

Expressive Therapies Capstone Theses

Abstract

Human/Sex trafficking is the use of force or coercion for the purpose of exploiting humans (mainly women) for sex or labor. Consequences of being trafficked include psychological and physical symptoms that may hinder the survivors for the rest of their life if not treated. Survivors of human trafficking are infrequently researched and have limited evidence-based methods of treatment. Even fewer studies have been conducted involving the use of dance/movement therapy with survivors of trafficking. dance/movement therapy is vital to treatment because of its focus on integrating the body with the mind. In this literature review I discuss the effects …

Post-Lysosomal Cholesterol Trafficking: Novel Tools And Insights, Mckenna Rae Feltes

Arts & Sciences Graduate Student Theses and Dissertations

Cholesterol is an essential mammalian lipid. It is a major component of cellular membranes, a precursor molecule for the synthesis of hormones and bile acids, and a regulator of protein function. Although cholesterol is synthesized, de novo, in the endoplasmic reticulum, cells principally meet cholesterol requirements through uptake of lipoprotein particles. Lipoprotein-derived cholesterol is transported to the lysosome where it is transferred from the soluble lysosomal protein, NPC2, to limiting-lysosomal membrane protein NPC1. Cholesterol is then re-distributed to other cellular membranes in order to fulfill organellar cholesterol requirements; however, the cellular machineries involved in coordinating this distribution are poorly characterized. …

Comparisons Of Patellar Bone Mineral Density Between Individuals With And Without Patellofemoral Pain, Chris Khuu, Allina Cummins, Steven Shepherd

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Although bone stress injuries have been reported in individuals with patellofemoral pain (PFP), especially within the lateral patella, it remains unclear whether persons with PFP exhibit altered patellar regional bone mineral density (BMD). The primary purpose of this study was to compare BMD of the patella (lateral, medial, and total regions) between individuals with and without PFP using quantitative computed tomography (QCT). The secondary aim was to examine the associations between patellar regional BMD and patellofemoral joint (PFJ) alignment. Methods: Ten individuals with retropatellar pain and 10 sex, age, weight, height, and activity matched pain-free controls underwent a QCT …

Band Power Analysis Of The Eeg Frequency Spectrum: An Evaluation Of Interictal Periods Of The Migraine Phase Using An Eyes-Open Vs. Eyes-Closed Resting State Paradigm, Andrea Perez-Munoz

Electronic Theses and Dissertations Archive

Migraine is a primary headache disorder characterized by abnormal cortical activity acrossmigraine phases. However, less is known about electroencephalographic activity present duringasymptomatic periods of the migraine cycle or during resting-state conditions. Given the theorythat these testing conditions may reflect more permanent cortical states, the present studyexamined the interacting role of resting-state conditions (eyes-open vs. eyes-closed) andheadache diagnosis (migraine vs. control) on absolute band power across the EEG frequencyspectrum. In-line with previous research, we hypothesized that interictal periods of the migrainephase would be characterized by a difference in alpha frequency and an increase in slow-waveactivity compared to controls. We further predicted …
