Native And Non-Native English-Speaking Doctoral Students' Strategies To Understand Idiomatics In Comics And Comic Strips, Himelhoch Luz-Aydé

USF Tampa Graduate Theses and Dissertations

Everyday language consists of many idiomatic and figurative expressions. For non-native English speakers to achieve native fluency, control of idiomatics—native speech that includes the use of both idiomatic and figurative language—is paramount. In this study, I aimed to explore the use of comics and comic strips in the learning and comprehension of L2 (second language) idiomatics. Seldom has the topic of comics and comic strips been addressed as it applies to idiomatics learning in second language acquisition (SLA). I employed a descriptive and exploratory approach in this study to address this gap in SLA pedagogy. A total of 21 doctoral …

USF Tampa Graduate Theses and Dissertations

On the afternoon of August 10th, 2020 a straight line windstorm, referred to as a derecho, tore across the Midwest. Derechos are often described as an “inland hurricane,” with wind gusts exceeding 58 mph. This thesis explores how Iowans relied on social networks to recover from the derecho. Personal networks were analyzed to understand how people utilized relationships for specific types of support. The relationships investigated included informal and formal sources such as family, friends, neighbors, government, volunteers, non-governmental organizations, and self-reliance. Data were collected on social networks and storm recovery through a survey and semi-structured interviews. Using anthropological theories …

Depression During Adolescence: An Examination Of Treatment Outcomes Through An Intersectional Lens, Myesha Morgan

USF Tampa Graduate Theses and Dissertations

Major Depressive Disorder is a common mental health disorder, with studies suggesting its potential to lead to academic and social-emotional impairment in youth (Alegria, Vallas, & Pumariega, 2011). Although psychological treatments for this disorder have been studied for decades, prior to recent years little was known about the generalizability of treatment effectiveness to non-European samples (Bernal, Bonila, & Bellido, 1995; Bernal & Scharron-Del-Rio, 2001). Data suggest that racial/ethnic minority youth experience more severe depression when diagnosed with the disorder and are less likely to access mental health services. Behavior Activation (BA) is a treatment approach found to be effective for …

Recognizing Patterns From Vital Signs Using Spectrograms, Sidharth Srivatsav Sribhashyam

USF Tampa Graduate Theses and Dissertations

Spectrograms extract frequency components from a signal. Spectrograms have beenin use for a long time mainly to analyze frequency components in audio signals. Typically, these audio signals have a very high sampling rate, various frequency components and high frequency variability with time. Vital signs on other hand have very low sampling rate with no frequency variability. This work explores if spectrograms can be used to analyze and recognize patterns from vital signs signals.

As mentioned above, spectrograms deal with frequencies. More the variability of frequency, better the patterns emerge when spectrograms are applied on the signals. As vital signs lack …

The Effects Of Critical Audit Matter Recurrence And Reporting Treatment On Investors’ Information Processing, Judgments, And Decisions, Hilda E. Carrillo

USF Tampa Graduate Theses and Dissertations

A new auditor reporting standard requires auditors to disclose critical audit matters (CAMs) in the auditor’s report. CAMs highlight accounts or disclosures that involved especially challenging, subjective, or complex auditor judgment. As one of few audit-related disclosures, CAMs act as an important signal of qualitative aspects of recognized (i.e., items shown on the face of the financial statements) or disclosed (i.e., items shown in the footnotes of the financial statements) financial statement items. While certain accounts or disclosures will consistently rise to the level of a CAM, other accounts or disclosures may only rise to the level of a CAM …

I conducted a qualitative study of participants in international package tourism and individual travelers, more specifically, Chinese tourists who travel to the United States. Main topics of exploration included tourists’ experience of their trips and package tours, how they interpreted American culture and compared it to their own, how they constructed and performed identities both as tourists and as Chinese nationals, their emotional experiences and how they made sense of an environment that they …

A New Age Of Telehealth: Pediatric Speech-Language Pathology Services During The Covid-19 Pandemic And Beyond, Deborah R. Campbell

USF Tampa Graduate Theses and Dissertations

The COVID-19 pandemic potentially changed the landscape of how speech-language pathologists provide services. Prior to March 2020, pediatric speech-language therapy provided via telehealth was limited; however, the COVID-19 pandemic caused a worldwide conversion from in-person care to a remote service delivery model. This conversion brought to the fore possible benefits and utility of telehealth use. Yet, clinicians potentially experienced barriers to its use, including the lack of validity and reliability evidence for remote administration of several pediatric assessments. For the viability of remotely delivered speech-language services to continue and evolve in a post-pandemic world, further research is needed to identify …

Cetacean Maternal Investment: Importance In Conservation Across Species And Drivers For Interspecific Altruism, Christopher Klein

USF Tampa Graduate Theses and Dissertations

Cetacean maternal investments can be useful for conservation management as well as examining behaviors such as interspecific altruism in the humpback whale, Megaptera novaeangliae. Cetaceans are among the most threatened group of marine mammals. In the second chapter, maternal investments across ~90 species/subspecies of Cetacea were analyzed to aid in the understanding of recovery/replacement for conservation and management. Using Principal Components Analysis (PCA), a relative maternal-investment index for 41 cetacean species was built. The maternal-investment index was a composite of four maternal-investment variables, the duration of gestation, lactation, calving intervals, and the number of reproduction years per female per species. …

Mitigating Negativity Bias In Media Selection, Gabrielle R. Jarmoszko

USF Tampa Graduate Theses and Dissertations

A growing body of research explores implicit negativity bias and how it influences news selection processes of media consumers. However, very little, if any, research exists exploring how negativity bias in the news selection process can be mitigated. Informed by experimental designs that have proven effective in mitigating other types of implicit bias, this study aimed to investigate whether having consumers commit themselves to definitions of their preferred type of news before engaging in the selection process alters manifestations of negativity bias in the selection. This study tested two hypotheses: H1, that non-committed individuals will have a higher selection frequency …

Feasibility Of A Virtual Group Nutrition Intervention For Adolescents With Autism Spectrum Disorder, Acadia W. Buro

USF Tampa Graduate Theses and Dissertations

Background: Youth with autism spectrum disorder (ASD) have an increased likelihood of being overweight or developing obesity. As children and adolescents with ASD exhibit problematic eating behaviors and may consume more energy-dense foods and fewer fruits and vegetables than typically developing youth, nutrition represents a modifiable obesity risk factor for adolescents with ASD, yet there is a lack of interventions to improve healthy eating and reduce the risk of obesity in this population.

Purpose: The purpose of this study was to examine the feasibility, acceptability, and preliminary efficacy of a virtual implementation of BALANCE (Bringing Adolescent Learners with Autism Nutrition …

“I Wish Somebody Called Me, Told Me Not To Worry”: Evaluating A Non-Profit’S Use Of Social Support To Address Refugee Women’S Resettlement Challenges, Brandylyn L. Arredondo

USF Tampa Graduate Theses and Dissertations

This report details the qualitative findings from an evaluation of the Refugee and Migrant Women’s Initiative (RAMWI) in Tampa, FL. Founded in 2013, the 501(c)(3) provides cultural knowledge and sewing classes to resettled refugee women. Using primarily semi-structured interviews and participant observation, I place a critical lens on the non-profit to examine how refugee women and volunteers use the provided resources and experience the values (e.g., empowerment, vulnerability) RAMWI centralizes in its programs.

Interviews with refugee women, volunteers, and key informants revealed that the challenges RAMWI faces derive from six key areas of contention: 1) an informal organizational structure; 2) …

“Be Valiente”: Investigating Ethnic Identity Through Digital Storytelling With Latinx Fourth-Grade Students, Jennifer Michelle Barreto

USF Tampa Graduate Theses and Dissertations

Multilingual and multicultural students face the challenge of understanding where their ethnic identity lies in learning. The education system in the United States lacks inclusivity in classrooms, continuing monocultural views and monolinguist ideals as the norm and encouraged in curriculum and standards (Flores, 2020). This dissertation study seeks to break cultural and linguistic ideologies to better understand the development of ethnic identity in three Latinx fourth-grade students by creating a digital story. Through a sociocultural lens that includes a bioecological model (Bronfenbrenner, 1977; Vélez-Agosto et al., 2017) and multimodality (NGL, 1996) framework the study emphasizes all funds of knowledge (Moll …

Making A Home Away From Home: A Qualitative Study Of African Students’ Practices Of Integration In The United States, Alphonse O. Opoku

USF Tampa Graduate Theses and Dissertations

Over the last two decades, the population of international students in the world has significantly increased. More and more students from diverse backgrounds cross national borders to study. The observed increase in numbers and diversity has led to an uptick in scholarly research that focuses on the adaptation and experiences of international students. Most of these studies, particularly in the US, are informed by the acculturation theories and assimilationist frameworks of the 1900s. Also, an exclusive focus is placed on the host country, with few studies acknowledging the impact of the origin country on the international student experience. Such approaches …

An Evaluative Pilot Study Of An Online Facilitator Professional Development Program, Alana Elkins

USF Tampa Graduate Theses and Dissertations

With a rapid increase in higher education online course offerings, many institutions are hiring part-time faculty to meet the demand of online learning. However, a lack of professional development in online course facilitation has proven to limit the effectiveness of facilitation and hinder the foundational quality standards the courses were built upon. An evaluative pilot study was conducted on a professional development framework provided to a group of online course facilitators that were hired to teach the course but did not participate in the online course developments. Since many course facilitators are not online faculty developers, they have limited knowledge …

Green Business And The Culture Of Capitalism: Constructing Narratives Of Environmentalism, Julia S. Jester

USF Tampa Graduate Theses and Dissertations

There are widespread colloquial arguments claiming that any actions taken to combat climate change will be bad for business and the economy, scaring people into continuing their support for the status quo for fear of their financial security. Alternatively, those attempting to combat ecological destruction have subsequently made transitions to sustainable development of products and shifting consumer behavior within this system. There is one core argument that both sides have, albeit in different ways – capitalism and environmentalism are seemingly incompatible; one cannot be successful without the eradication of the other. While it may appear there are only strict binary …

Reference-Dependent Choice On Digital Platforms, Joshua K. Kaisen

USF Tampa Graduate Theses and Dissertations

Throughout this dissertation I explore a significant departure from the standard model of rationality known as reference-dependence. The theory reference-dependence asserts that an individual’s choice is dependent on their frame of reference established through factors divorced from their rational cost and benefit. This behavior is inefficient as individuals fail to rationally optimize their payoffs. This behavior is understudied in natural settings where isolating specific stimuli which may establish a reference is challenging. However, digital platforms contain limited stimuli which are fully observable to researchers and present an ideal setting to study the theory of reference-dependence. Thus, I introduce three new …

Site Suitability Modeling In The Sand Pine Scrub Of The Ocala National Forest, Jelane M. Wallace

USF Tampa Graduate Theses and Dissertations

Central Florida’s Ocala National Forest is the largest remnant of the unique-to-the-region Sand Pine Scrub ecosystem. This ecosystem exhibits a surprising wealth of biodiversity despite what may be characterized as barren, difficult, dry, pyrogenic conditions. Significant prehistoric sites exist throughout the forest, even in the Sand Pine Scrub; however, most are on the margins and few systematic surveys penetrated this ecosystem, until now. I utilized GIS and these recently collected archaeological survey data, in conjunction with other environmental, geological, or historical data in GIS format, to model prehistoric settlement and land use patterns. This model attempts to address questions of …

Optimization And Machine Learning Methods For Solving Combinatorial Problems In Urban Transportation, Aigerim Bogyrbayeva

USF Tampa Graduate Theses and Dissertations

This dissertation investigates three applications of emerging technologies for urban trans- portation. In the first chapter, we design a new market for fractional ownership of au- tonomous vehicles (AVs), in which an AV is co-leased by a group of individuals. We present a practical iterative auction based on the combinatorial clock auction to match the interested customers together and determine their payments. In designing such an auction, we con- sider continuous-time items (time slots) which are defined by bidders, and naturally exploit driverless mobility of AVs to form co-leasing groups. To relieve the computational burdens of both bidders and the …
