The Nature Of Resilience: A Person-Centered Approach Using Latent Profile Analysis, Yuejia Teng

USF Tampa Graduate Theses and Dissertations

Resilience research has become increasingly popular in organizational sciences in recent years. Different factor structures of resilience have been proposed and yet no consensus has been reached regarding its underlying dimensions. Such a variable-centered perspective of studying resilience may be well complemented by a typological approach, which may shed fresh light on the nature of resilience. The current study took a person-centered approach with the advantage of using latent profile analysis to explore a set of latent profiles of resilience. Two studies were conducted. In Study 1 (N = 479), archival undergraduate data were used to explore resilience profiles and …

Measuring Parental Involvement As Parental Actions In Children’S Private Music Lessons In China, Cancan Cui

USF Tampa Graduate Theses and Dissertations

Anonymity has long been discussed as a source of disinhibition. The myth of the Ring of Gyges illustrates how a person may act immorally solely because they know they will not be caught (Plato, 375/2017). Incorporating perspectives of rational choice and deterrence, anonymity serves as a form of risk reduction within hedonistic calculus (Beccaria, 1764/1963; Bentham, 1781/2000). Analogous to the myth of the Ring of Gyges (Plato, 375/2017), techniques of anonymity “hide” users from others while online. These techniques serve as a form of risk reduction, reducing the certainty of punishment (Becarria 1764/1963). Additionally, there are many ways by which …

The Adaptive, Social, Communication, And Cognitive Skills Of Monolingual And Bilingual Toddlers With Autism, Marcela A. Galicia

USF Tampa Graduate Theses and Dissertations

The rates of Autism Spectrum Disorder (ASD; Center for Disease Control [CDC], 2019) and bilingual individuals are rapidly increasing in the United States (Zeigler & Camarota, 2019). Yet, research on the global development of bilingual children with ASD is limited. Despite the lack of research in this vein, educators and clinicians are tasked with the assessment and intervention planning for culturally and linguistically diverse (CLD) children with ASD (Dilly & Hall, 2019). There are mixed findings regarding the effect of bilingual exposure on the development of adaptive, social, communication, and cognitive skills of children with ASD (e.g., Hambly & Fombonne, …

School Nurses’ Attitudes And Perceptions Toward Supporting Students With Chronic Health Conditions In An Ecological System, Destiny L. Singleton

USF Tampa Graduate Theses and Dissertations

Chronic health conditions impact one in four school-aged youth (Van Cleave, Gortmaker, & Perrin, 2010). Supplemental to the medical challenges that students with chronic health conditions face, they also are at risk for a variety of academic, behavioral, and social-emotional adversities. Using an ecological approach for addressing the diverse needs of students with chronic health conditions has been deemed valuable due to the array of key stakeholders, institutions, policies, and cultural norms that impact the development of the pediatric population. A key stakeholder in supporting the functioning of school-aged children with chronic illnesses is the school nurse. School nurses’ skills …

Early Indicators Of Cognitive Dysfunction: The Role Of Mild Behavioral Impairment, Hillary J. Rouse

USF Tampa Graduate Theses and Dissertations

Older age is associated with an increased risk for cognitively impairing diseases such as dementia. Despite significant research to find ways to cure this disease, there has been little success. However, a critical need when an intervention is discovered is a need to find ways to identify people who are at the greatest risk of developing dementia earlier in the disease process so that interventions can be implemented at that time. This could potentially lessen their risk or delay when they are diagnosed. Using longitudinal data from the National Alzheimer’s Coordinating Center (NACC), the aims of this current dissertation were …

An Evaluation Of Distributed And Accumulated Reinforcer Arrangements On Skill Acquisition And Preference, Natalie R. Mandel

USF Tampa Graduate Theses and Dissertations

Discrete trial training (DTT), an evidence-based instructional procedure (Wong et al., 2015), is often used to teach skills to individuals with autism. Manipulations to the reinforcement component of DTT have increased its instructional efficiency, resulting in acquisition of skills in less time (e.g., Cividini-Motta & Ahearn, 2013). Results of previous studies (e.g., DeLeon et al., 2014) indicate that some individuals prefer to complete larger work requirements that result in a larger amount of a reinforcer (i.e., accumulated arrangement), rather than receiving access to small amounts of a reinforcer dispersed throughout the work requirement (i.e., distributed arrangement). In addition, accumulated reinforcer …

Development Of A Bipolar Radiofrequency Ablation Device For Renal Denervation, Noel Perez

Transcriptomic And Functional Investigation Of Bacterial Biofilm Formation, Brooke R. Nemec

USF Tampa Graduate Theses and Dissertations

Staphylococcus aureus and Acinetobacter baumannii are two highly successful human pathogens, which have adopted very different, but effective survival strategies. The success of S. aureus is attributed to the tight regulation of an arsenal of virulence factors. Conversely, A. baumannii lacks what would be considered traditional virulence factors and, instead, has developed a high tolerance for environmental stress, which allows it to persist in unforgiving environments, including nosocomial settings and the human body. One common characteristic of these two organisms is their proclivity for biofilm formation. Herein, we discuss the diverse mechanisms governing biofilm formation for A. baumannii and S. …

A Comparative Thematic Analysis Of Newspaper Articles In France After The Bataclan And In The United States Of America After Pulse, Simon Rousset

USF Tampa Graduate Theses and Dissertations

This project interrogates unequal power relations that underlie newspaper representation of terrorism and reinforced Orientalism discourse following the 13 November 2015 mass murders in Saint-Denis and Paris, France, and following the 12 June 2016 mass shooting in Orlando, Florida, United States of America (U.S.A.). It was not surprising to bear witness to the ways national media took hold of these major socio-political events. These events, and the stories that have been published about them, are interpreted through the prism of terrorism, moral panic, and Orientalism, in the sense that the media tend to transcribe the shock of the attacks as …

The Effects Of Agrochemical Pesticide Applications On Target And Off-Target Species In Aquatic Ecosystems, Bryan K. Delius

USF Tampa Graduate Theses and Dissertations

The increase in the global human population is driving agricultural expansion, which increases the likelihood and degree by which agrochemicals impact aquatic systems. It is projected that by 2100 the global human population will exceed 11 billion, and to feed the increased human population, the necessary increase in agricultural infrastructure is estimated to double irrigation, nearly triple fertilizer applications, and increase pesticide applications by tenfold. It stands to reason that wetlands impacts from agriculture are also likely to increase as the industry expands its operation to meet the globally growing demand for food.

Wetlands are highly productive habitats that not …

Data-Driven Studies On Social Networks: Privacy And Simulation, Yasanka Sameera Horawalavithana

USF Tampa Graduate Theses and Dissertations

Social media datasets are fundamental to understanding a variety of phenomena, such as epidemics, adoption of behavior, crowd management, and political uprisings. At the same time, many such datasets capturing computer-mediated social interactions are recorded nowadays by individual researchers or by organizations. However, while the need for real social graphs and the supply of such datasets are well established, the flow of data from data owners to researchers is significantly hampered by privacy risks: even when humans’ identities are removed, or data is anonymized to some extent, studies have proven repeatedly that re-identifying anonymized user identities (i.e., de-anonymization) is doable …

A Review Of Marine Turtle Orientation And Artificial Lighting Impacts With Novel Results From Florida’S Gulf Coast, Andrea M. Fisher

USF Tampa Graduate Theses and Dissertations

Artificial light (i.e. unnatural light emitting from a human-made source) is one of the most extensively distributed, and least managed, type of anthropogenic pollution. Due to the disproportionally high rates of urbanization in critical coastal ecosystems, species, like marine turtles that use beach habitat for nesting activities, are especially vulnerable. Marine turtles employ the use of multiple visual cues (e.g. wavelength, intensity, background illumination, and dark silhouettes) to conduct sea-finding behavior and different variations in cue usage exist across species and geographic location. During nesting and emergence activities, orientation can be interrupted and manipulated by artificial lighting resulting in lower …
