Home Is Where The Work Is: How Biases In Managers’ Resource Allocation Decisions Affect Task Performance In Remote Work Environments, Richard D. Mautz Iii

USF Tampa Graduate Theses and Dissertations

As the use of remote and hybrid work arrangements continues to grow, it is important to understand how these arrangements can yield performance. In this paper, I conduct two studies to examine how the remote work environment affects managers’ task assignment decisions across different task types and how those decisions affect workers’ task performance. First, I survey managers, in both a cross-section of industries and specifically in accounting, to study the effect of remote work on their task assignment decisions. Consistent with prior literature and economic theory, I predict and find that managers are more inclined to assign generative tasks …

Count Me In: A Study Of Social Validity, Positive Behavioral Interventions And Supports, And A High School, Amie Dia Davis

USF Tampa Graduate Theses and Dissertations

The implementation of Positive Behavioral Interventions and Supports (PBIS) has been attributed to a decrease in office discipline referrals (ODRs) and suspensions and to increase academic performance, and engagement, as well as staff, family, and student perceptions of a safe and positive school climate. High schools have had more significant issues than elementary sites with implementing PBIS and garnering staff support due to larger faculty, staff, and student size, multi-faceted organizational culture, and the age of the students served. In addition, factors that have also been cited as inhibiting successful implementation at the high school level are lack of student …

The Cooperation Of Russia And Iran-Led Shia Axis:Its Nature And Implications For The U.S. Strategy In The Middle East, Arman Mahmoudian

USF Tampa Graduate Theses and Dissertations

This dissertation examines the intricate dynamics of the partnership between Russia and the Iran-led Shia Axis formed during the Syrian civil war (2011-present), a coalition of Iran-supported state and non-state Shia entities in Iraq, Syria, and Lebanon. This alliance is distinguished by its unprecedented nature: a secular, authoritarian Russia aligning with a network of Shia groups, a collaboration forged amidst shared concerns over Syrian rebels and Sunni extremists, particularly ISIS. Remarkably, this partnership has evolved beyond its initial focus on immediate threats, suggesting a deeper, strategic alignment aimed potentially against a more formidable adversary, the United States.

Unveiling Estrangement: The Ambivalence Of Iranian Cultural Identity In Documentary Films, Vahid Valikhani

USF Tampa Graduate Theses and Dissertations

This paper examines estrangement within Iranian society as depicted in Iranian documentaries, which, I argue, regularly suppress the complexities of Iranian cultural identity. While Iranian narrative cinema has been studied in this context, documentaries have received less scholarly attention, despite their potential to illuminate the shortcomings of conceiving Iranian cultural identity. I examine three documentaries: Tehran Today (Ahmad Faroughi Ghajar, 1962), Newcomers (Kianoush Ayari, 1979) and Tehran Without Permission (Sepideh Farsi, 2009). Through this analysis, I uncover various forms of estrangement, including those induced by westernization, gender oppression, and the political control of what Hamid Naficy calls “mediawork.” Drawing on …

Modeling Studies Of An Intensified Reforming/Fischer-Tropsch Synthesis Process For Gas To Liquid Conversion, Brian Gray

USF Tampa Graduate Theses and Dissertations

Despite rigorous study and advancement in fields of green energy, the world's transportation industry remains poised to continue reliance on liquid hydrocarbon fuels. To date, the primary source of diesel and jet fuels is the petroleum industry; however, continuing trends in rising greenhouse gas emissions present a need for study into processes for the production of synthetic hydrocarbon fuels. The most promising technologies to meet this goal are gas-to-liquid (GtL), biomass-to-liquid (BtL) and coal-to-liquid (CtL). The commonality of these technologies is that they utilize a feedstock to produce carbon monoxide and hydrogen gas (syngas) which becomes the building blocks of …

Forgotten Learners: An Examination Of The Experiences Of English Language Learners In Advanced Placement And International Baccalaureate Social Studies Courses, Elizabeth Rasmussen

USF Tampa Graduate Theses and Dissertations

The number of English Language Learners (ELLs) in the United States is rapidly increasing, particularly in high schools. Although the number of ELLs is growing at a fast pace in the United States, the number of ELLs enrolled in advanced educational programming has not increased. After an in-depth review of the extant literature, it is evident that limited scholarly research on ELLs in advanced coursework exists. This is especially true in AP and IB social studies courses, where in many states where “Open Access” and “AP for All” have been adopted. This qualitative study sought to reveal the lived experiences …

Multiple Shots To Understanding Gun Violence, Lexi Gill

USF Tampa Graduate Theses and Dissertations

Gun violence is a ubiquitous issue across the United States, and recently, gun violence surpassed the previously recorded highest rates. Each year, tens of thousands of individuals lose their lives to gun-related violence. Gun violence is the leading cause of death among youth and disparately impacts young Black men. Some suggest gun violence is a social contagion that transmits from one individual to another and circulates through certain communities, suggesting gun violence can be “cured” with the appropriate treatment. Despite the proliferation of gun violence, current research on gun violence is underdeveloped. It is imperative to assess gun violence from …

Exploring The Associations Between Drug Resistant Mutations, Low-Level Viremia, And Virological Failure In Persons With Hiv In Florida, Adriana Campos

USF Tampa Graduate Theses and Dissertations

Virologic suppression is an essential part to a successful regimen for Persons with HIV (PWH) and the 95-95-95 initiative. Yet, PWH experiencing episodes of low-level viremia (LLV) may be more prone to experience virological failure (VF). Currently, studies debate the clinical relevance of LLV and its effect on virological outcomes, but none have explored its interconnectedness with drug resistant mutations (DRM) and antiretroviral treatment (ART) adherence – all integral elements in predicting virological outcomes.

The goal of the proposed study was to contribute to the knowledge gap regarding the interconnectivity of drug resistant mutations, low-level viremia, adherence, and virological failure …

Community-Centered Early Warning For Outbreaks In Humanitarian Emergencies: Evaluating Community-Based Surveillance For Priority Communicable Diseases Among Internally Displaced Populations In Iraq, Caitlin M. Wolfe

USF Tampa Graduate Theses and Dissertations

Background: Community based surveillance (CBS) is the organized and rapid collection of information from health events identified in the community and includes the systematic detection and reporting of events of public health significance. While used globally to enhance the detection of priority diseases, CBS has not been routinely deployed in Iraq, where a once-robust health system has been devastated by decades of war, international sanctions, and large-scale population displacement. During infectious disease outbreaks, it is imperative to quickly detect and isolate suspect cases, investigate confirmed cases, and trace and monitor the contacts of confirmed cases. The COVID-19 pandemic underscored the …

Integrating Identities By Segmenting Domains: Antecedents Of Work-Maternal Identity In The Postpartum Return To Work, Aashna M. Waiwood

USF Tampa Graduate Theses and Dissertations

As employed women have children and return to work, they encounter a cross-domain identity transition where their professional and maternal identities are consistently co-activated and must perceptually contend with one another. In this dissertation, I explored this potential for harmonious assimilation of work and parental identities within this postpartum transitory period via a novel construct termed “work-maternal identity (WMI).” Specifically, I examined how working remotely in integrated work and home environments is related to WMI, as mediated by job engagement and perceptions of work belongingness. I also incorporated factors critical to successful resocialization and related to boundary management as moderators …

Lawful Injustice: Novel Readings Of Racialized Temporality And Legal Instabilities, Danielle N. Mercier

USF Tampa Graduate Theses and Dissertations

This project, “Lawful Injustice: Novel Readings of Racialized Temporality and Legal Instabilities,” examines three specific BIPOC communities across literature—Native American, African American, and Asian American—to understand the influence of U.S. legal frameworks and temporalities upon both the collective and the individual. I assess how legal frameworks create and protect their own instabilities as well as understand how they are produced by the uneven temporal structures of the law. I examine how such legal and settler colonial temporalities are at odds with Native American, African American, and Asian American temporalities. These temporalities—a legal/juridical temporality which reinscribes settler colonial oppression and the …

Leveraging Systems Thinking For Global Environmental Health, Martha M. Mcalister

USF Tampa Graduate Theses and Dissertations

Environmental health inequities such as household air pollution, inadequate water, sanitation, and hygiene, and chemical pollution persist globally and have myriad consequences on individual and societal well-being. Unfortunately, while billions of dollars and countless hours of research have been applied towards addressing these issues in development, humanitarian, and environmental justice contexts, attempts to reduce the environmental burden of disease can seem successful at first, but then backslide to pre-intervention conditions (or worse). This is indicative of policy resistance, a tendency of complex systems that makes it very difficult to enact change if the “rules” of the system are misunderstood. There …

Employer Moral Hazard In Performance Evaluations: The Effects Of Performance Measure Subjectivity And Justification On Employer Opportunism, Chandler A. Miller

USF Tampa Graduate Theses and Dissertations

Although organizations may use multiple types of performance measures when evaluating employee performance, such as objective and subjective measures, performance measure subjectivity can introduce unverifiable information on the employee side, giving rise to employer opportunistic behavior. Employers may use the unverifiable information within subjective performance measures to increase their own personal compensation by undercompensating evaluated employees, creating a control problem known as employer moral hazard. With a 2x2 multi-period experiment, this study investigates the effect employer moral hazard has on the allocation of employee bonus compensation when there are differing levels of objective and subjective performance measures and a requirement …

Curricula As Ideology: A Study Of Cultural Representations In Arabic As A Foreign Language (Afl) Textbooks, Zakaria Fahmi

USF Tampa Graduate Theses and Dissertations

The present study examines cultural representations in two widely used AFL textbook series, namely Al-Kitaab and Arabiyyat al-Naas. Fundamentally, three main issues motivate this study: (1) the cultural politics of language textbooks underlying the construction and dissemination of cultural knowledge and its prioritization of the latter on grounds of subjectivity, ideology, and power, (2) the politicization of Arabic as a foreign language (AFL) in light of the post 9/11 language advocacy, and (3) the prevailing standard language ideology of al-Arabiya al-fuṣħaa (العربية الفصحى) and the pedagogical challenges posed by Arabic diglossia.

African Spirituality In Literature Written By Women Of African Descent, Brigét V. Harley

USF Tampa Graduate Theses and Dissertations

African spiritual memory is the thread that connects members of the African diaspora, irrespective where we are or what we are doing. However, because of white supremacy, the longevity of African spiritual memory and its duration as a living, thriving, breathing force often becomes distorted under the weight of anti-black prejudice. This dissertation debunks the myth that people of African descent required outside input from non-Africans and Arabs to establish the world’s oldest and most studied civilizations, Ta-Seti and then the Egyptian Empire. Women writers of African descent capture the ever-present thread of African spiritual memory, providing a glimpse of …

The Drama Of Last Things: Reckoning In Late Medieval And Early Modern English Drama, Spencer M. Daniels

USF Tampa Graduate Theses and Dissertations

Historian Albrecht Classen’s contention that “the culture of death . provides us with a measuring stick for human society at large” is particularly illuminating when analyzing death and Christian salvation near the religious chasm of the Reformation divide. My study focuses on reckoning as it is illustrated in late medieval and early modern allegorical English drama. The Christian belief in a soul’s redemption or damnation after death was preceded by a crucial supernatural happening, a reckoning. Informed by God’s judgment, this event became the crux of the ars moriendi (the art of dying) tradition that permeated medieval and early modern …
