The Effects Of Using Textual Enhancement On Processing And Learning Multiword Expressions, Adel Zain Alshaikhi

USF Tampa Graduate Theses and Dissertations

Multiword Expressions (MWEs) are crucial aspects of language use. Second language (L2) learners need to master these MWEs to be able to communicate effectively. In addition, mastering these MWEs helps L2 learners improve their cognitive processing of language input. In this study, my primary objectives were to explore the effectiveness of using Textual Enhancement (TE) to assist L2 speakers’ comprehension of MWEs, to explore whether there is a difference in comprehension between collocations and idioms, and finally, to explore how L2 speakers transact the MWEs’ meanings as presented in texts.

While several researchers have explored how input enhancement in general …

Mirror Images: Penelope Umbrico’S Mirrors (From Home Décor Catalogs And Websites), Jeanie Ambrosio

USF Tampa Graduate Theses and Dissertations

As the artwork’s title suggests, Penelope Umbrico’s "Mirrors (from Home Décor Catalogs and Websites)" (2001-2011), are photographs of mirrors that Umbrico has appropriated from print and web based home décor advertisements like those from Pottery Barn or West Elm. The mirrors in these advertisements reflect the photo shoot constructed for the ad, often showing plants or light filled windows empty of people. To print the "Mirrors," Umbrico first applies a layer of white-out to everything in the advertisement except for the mirror and then scans the home décor catalog. In the case of the web-based portion of the series, she …

USF Tampa Graduate Theses and Dissertations

Border-Crossing Travels Across Literary Worlds is an autocritographical journey that places a group of U.S. literary texts into critically conscious dialogue with the “text” of my life. As a white, American, middle-class, cishetero, able-bodied man, I historicize, contextualize, analyze, and deconstruct the process by which my ten years of graduate academic studies at the University of South Florida fostered my ongoing awakening to critical consciousness—the personal and political evolution Paolo Freire terms “conscientization.” I present the analytical insights I realized about landmark feminist and womanist texts I encountered during my graduate studies that resonate with the prominent literary works and …

Assessing The Cooling Effects Of Urban Vegetation On Urban Heat Mitigation In Selected U.S. Cities, Qiuyan Yu

USF Tampa Graduate Theses and Dissertations

Urban Heat Island (UHI) is a growing problem worldwide. Mitigation of UHI is necessary for cities to adapt to climate change and enhance sustainable development at a city scale. Cooling cities with urban vegetation management is a sustainable solution for urban heat mitigation. Urban vegetation influences urban microclimate through the shading effect, surface roughness, and evapotranspiration. The differences in horizontal and vertical structures of urban vegetation determine the shading effect, surface roughness, and evapotranspiration. Enhancing the cooling effect of urban vegetation requires a comprehensive understanding of how vegetation structure affects UHI. The effects of horizontal structure on land surface temperature …

Flowgraph Models For Clustered Multistate Time To Event Data, Kristin Hall

USF Tampa Graduate Theses and Dissertations

Healthcare systems have multistate processes. Such processes may be modeled using flowgraphs, which are directed graphs. Flowgraph models support a variety of transition time distributions, easily handle reversibility between states and allow alternate paths to the event or state of interest to be taken. However, estimation of flowgraph and first passage time distribution parameters can lead to incorrect inferences when interdependent data are treated as independent.

In this dissertation, we expand the flowgraph model to accommodate nested and correlated data structures. We develop a framework to incorporate random effects into transition probability and transition time components of a flowgraph model. …

Behavioral Thermoregulation And Thermal Mismatches Influence Disease Dynamics In Amphibians, Erin Louise Sauer

USF Tampa Graduate Theses and Dissertations

Amphibians are currently the most threatened vertebra taxa on the planet. Hundreds of species are thought to have gone extinct while thousands more have been listed as threatened or endangered over the past few decades. Habitat loss, invasive species, climate change, and disease are all thought to have partially contributed to these declines. Two pathogens in particular, infectious viruses in the genus Ranavirus (simply referred to as ranavirus) and the fungus Batrachochytrium dendrobatidis (Bd), have been associated with global mass mortality events of amphibians. Virulent pathogens such as these tend to impose strong selective pressures on their hosts driving the …

Early Identification Of Students In Accelerated Curricula With Signs Of Academic And Emotional Risk: Working With Teachers To Identify At-Risk Students, Elizabeth D. Storey

USF Tampa Graduate Theses and Dissertations

As part of a comprehensive, multi-tiered system of support for students’ emotional, academic, and behavioral success, effective universal screenings are essential to identify students who may benefit from early intervention and targeted prevention services (Strein, Kuhn-McKearin, & Finney, 2014). Although many screening procedures and methods have been developed and evaluated for general education populations, more research is needed on screening procedures designed for one traditionally underserved population in school-based mental health services—students in accelerated curricula (namely, students in Advanced Placement classes or in the International Baccalaureate program; AP/IB). When teachers are involved in universal screening procedures, regardless of student population …

Aqueous Humor Dynamics And The Constant-Pressure Perfusion Model Of Experimental Glaucoma In Brown-Norway Rats, Kayla R. Ficarrotta

USF Tampa Graduate Theses and Dissertations

Glaucoma affects tens of millions of people and is the leading cause of irreversible blindness worldwide. Virtually all current glaucoma therapies target elevated intraocular pressure (IOP); however, the contribution of intracranial pressure (ICP) to glaucoma has recently garnered interest. Strain at the optic nerve head is now known to depend on the translaminar pressure difference (TLPD), which is the difference between IOP and ICP, rather than IOP alone. A better understanding of how IOP and ICP relate to glaucoma development and progression is essential for developing improved therapies and diagnostic tests. Glaucoma is commonly modeled in rats, yet aqueous humor …

Message Received? The Relationship Between Graphic Warning Labels, Message Framing, And Psychological Responses Among Smokers, John B. Correa

USF Tampa Graduate Theses and Dissertations

Introduction: This study was designed to evaluate the effects of graphic components and message content on daily smokers’ responses to cigarette pack warning labels. It was hypothesized that graphic warning labels (GWLs) would produce increases in state psychological reactance, that loss-framed messages would generate increases in risk perception and psychological reactance, and that GWLs and gain-framed messages would interact to generate increases in motivation to quit smoking when compared to the GWL/loss-framed condition. It was also hypothesized that trait reactance, smoking behavior, and baseline motivation to quit smoking would moderate effects of the warning label exposures.

Method: In a within-subjects …

Validation Of A New Concept For Measuring Respirable Dusts, Xiao Liu

USF Tampa Graduate Theses and Dissertations

Sampling of airborne dust in industry is influenced by the potential health effects associated with human exposure. Health effects depend on mass concentration and particle size which influences the site of pulmonary deposition. Occupational diseases tend to be associated with dust deposition in specific regions of the respiratory tract. The ACGIH size selective TLVs are expressed in three forms: Inhalable Particulate Matter, Thoracic Particulate Matter, and Respirable Particulate Matter. In pneuomoconioses, the amount of dust deposited in the lungs can be estimated by sampling the respirable fraction. Dose-response relationships are derived by relating the health experience of workers to the …

Control Of Uncertain Dynamical Systems With Spatial And Temporal Constraints, Ehsan Arabi

USF Tampa Graduate Theses and Dissertations

The overarching objective of this dissertation is the development of feedback control frameworks for uncertain dynamical systems that are subject to spatial and/or temporal constraints. These spatiotemporal constraints usually arise from the physical and/or performance characteristics associated with a considered dynamical system in safety-critical applications, where synthesis and analysis of feedback control laws are not trivial. Specifically, the proposed control architectures in this dissertation mainly contribute to the model reference adaptive control and finite-time control literature. In particular, unlike existing model reference adaptive control approaches that are not capable of enforcing user-defined performance guarantees without an ad-hoc tuning process, the …

On The Feasibility Of Profiling, Forecasting And Authenticating Internet Usage Based On Privacy Preserving Netflow Logs, Soheil Sarmadi

Harnessing Social Norms To Increase Men's Interest In Heed Careers, Joanna R. Lawler

USF Tampa Graduate Theses and Dissertations

Men’s underrepresentation in the female-dominated domains of healthcare, early education, and the domestic sphere, or HEED roles, remains a persistent problem despite the fact that such careers often afford more job security and wage growth than blue-collar work. A growing body of evidence suggests that their lack of participation in HEED roles is not merely due to a skills mismatch, but rather an identity mismatch. I hypothesized that using descriptive and injunctive norms to reframe a stereotypically feminine career as more compatible with manhood could effectively reduce this identity mismatch. More specifically, I predicted that using a dynamic descriptive norm …

Managing A Food Health Crisis: Perceptions And Reactions To Different Response Strategies, Yifei Ren

USF Tampa Graduate Theses and Dissertations

Brand crisis could threaten a company with declining public trust and decreased brand reputation (Greyser, 2009). When confronting with a crisis, the organization should respond immediately and properly so that the crisis can be stopped from escalate into a catastrophe (Davies and Walters, 1998). Crisis type can be divided into the victim, the accident or the intentional clusters according to perceived responsibilities the company should shoulder. Based on these factors, the company should select the most appropriate response strategy or a combination of different response strategies to address the crisis situation. In other words, a match between crisis type and …
