Pragmatic Competence In Efl Context: Suggestions In University Office Hour Discourse, Hatime Ciftci

USF Tampa Graduate Theses and Dissertations

Office hour interactions at universities are one type of communicative activity in which international instructors and their Turkish EFL students are involved as a form of academic or institutional discourse (Drew & Heritage, 1992). In such real world communication, both parties employ several linguistic strategies and attend to various interactional goals to address the academic concerns at hand (Chiang, 2011; Chiang & Mi, 2008; Limberg, 2007; 2010; Reindhart, 2010; Skyrme, 2010). Embracing a discourse analytic approach, this study investigated the primary functions and topics of office hour interactions; discourse organization of office hour interactions with regard to the features of …

An Investigation Of The Relationship Between Face-To-Face Orientations, Instructor Verbal Immediacy Behaviors, And Persistence In Online Courses, Donald Painter, Jr.

USF Tampa Graduate Theses and Dissertations

The persistence rate in online classes remains significantly lower than in comparable face-to-face classes. There is a lack of research on strategies to help learners persist in online classes. The purpose of this study was to investigate the relationship between face-to-face orientations, instructor verbal immediacy behaviors, and persistence in online classes. It also explored the relationship between verbal immediacy and student satisfaction. Due to the disagreement in the literature, this study also investigated the relationship between student demographic variables, grade point average, and persistence.

This quantitative study combined both causal-comparative and correlational research methods. The study took place at a …

Characterization Of Two Novel Gene Regulatory Systems In The Zoonotic Bacterium Bartonella Henselae, Nhan Tu

USF Tampa Graduate Theses and Dissertations

The genus Bartonella contains Gram-negative arthropod-borne bacteria that are found in many small animal reservoirs and are capable of causing human disease. Bacteria utilize a general stress response system to combat stresses from their surrounding environments. In α-proteobacteria, the general stress response system uses an alternate σ factor as the main regulator and incorporates it with a two-component system into a unique system. Our study identifies the general stress response system in the α-proteobacterium, Bartonella henselae, where the gene synteny is conserved and both the PhyR and alternate σ factor have similar sequence and domain structures with other α-proteobacteria. …

The Common Core State Standards: Its Reported Effects On The Instructional Decision Making Of Middle School Social Studies Teachers, Tracy Tilotta

USF Tampa Graduate Theses and Dissertations

The Common Core State Standards (CCSS) for social studies are based on critical thinking and literacy skills. These new mandates are expected to lead to curricular and instructional changes within social studies classes. This qualitative study explored how the CCSS might have impacted the curricular and instructional decision-making of middle school social studies teachers and ultimately how the CCSS might affect a teacher’s gatekeeping role. As the CCSS initiative is fairly new, there is little research on the instructional practices being used to support the needs of teachers implementing these new standards in their classrooms as well as the processes, …

Now, We Hear Through A Voice Darkly: New Media And Narratology In Cinematic Art, James Anthony Ricci

USF Tampa Graduate Theses and Dissertations

This dissertation explores the intersection of new media and narrative, as it is presented through a cinematic aesthetic. The narrative language of film is analyzed through the theoretical framework of Bakhtin’s concepts of Heteroglossia, Chronotope, and Dialogism. Bakhtin’s ideas of classifying language act as strong tools for demonstrating how cinematic narrative can inform and alter the perception of its spectators. Lev Manovich’s principles of New Media, specifically Variability, Modularity, and Automation are also utilized to demonstrate how cinema is a constantly evolving paradigm.

Chapter one focuses on the theoretical terminology, outlining the conceptual definitions and illustrating their relevance in precise …

Modeling Alphabet Skills As Instructive Feedback Within A Phonological Awareness Curriculum, Arnold Olszewski

USF Tampa Graduate Theses and Dissertations

This study investigated the use of instructive feedback for modeling early literacy skills. Instructive feedback is defined as the presentation of additional information during the positive feedback phase of learner trials. Thus, it is a way of modeling additional information when students respond to a trial correctly. Previous studies have demonstrated that instructive feedback can facilitate students’ observational learning of skills, such as sight words, numerals, and vocabulary. Instructive feedback has yet to be investigated when modeling early literacy skills.

A modified version of an evidence-based early literacy intervention, PAth to Literacy, was used. Studies examining the efficacy of …

Phosphorus Sorption Dynamics In Shallow Groundwater, Coastal Everglades, Florida, Usa, Hilary Flower

USF Tampa Graduate Theses and Dissertations

For this dissertation I studied phosphorus (P) sorption dynamics in the shallow groundwater of the southern Everglades. In particular, I examined how the ambient water type governs soluble reactive P (SRP) availability through adsorption/desorption reactions with the aquifer matrix. Chapter 2 investigated how P sorption dynamics of the mangrove root zone sediment are affected by high bicarbonate brackish groundwater compared to both fresh groundwater and saltwater. The results from chapter 2 show that the sediment exhibited exceptionally low sorption efficiency in the high bicarbonate brackish water, which would allow ambient water SRP concentration to be maintained at a higher level. …

The Association Between Sexual Harassment And Suicidality Among College Women, Renee Brown Hangartner

USF Tampa Graduate Theses and Dissertations

The prevalence of sexual harassment among college women has been reported to range from 33% to 97% (Klein, Apple, & Khan, 2011; Yoon, Funk, & Kropf, 2010) across the lifespan. In any one year of college, the prevalence of sexual harassment reported by women ranges from 33% to 57% (Crown & Roberts, 2007; Huerta, Cortina, Pang, Torges, & Magley, 2006). The severity and frequency of sexual harassment has been found to be related to reports of psychological distress (Nielsen & Einarsen, 2012), feelings of shame (Yoon et al., 2010), anxiety and depression symptoms (Murdoch, Pryor, Polusny, & Gackstetter, 2007), and …

At The Intersection Of Human Agency And Technology: Genetically Modified Organisms, James Libengood

USF Tampa Graduate Theses and Dissertations

Since the Neolithic period and the rise of agriculture along Mesopotamia’s “Fertile Crescent,” greater societies have formed thus requiring laws and governance to ensure their continued preservation. The Babylonian Code of Hammurabi is one such example of how agricultural technologies directly created new social and institutional structures in codifying slavery into law, or how mercantile transactions are to be conducted. Similarly, GMOs are the result of modern agricultural technologies that are altering laws and society as a result of their implementation. This transformation informs the central inquiries of my research question: Why are GMOs necessary, and what influences do they …

The Effect Of An Alcohol Cue On A Risk Taking Task, Patrick Mcgee Logan

USF Tampa Graduate Theses and Dissertations

Laboratory-based tasks of impulsivity and related constructs can be useful in predicting alcohol use. Performance on these tasks is generally assumed to reflect traits that remain stable across situations. However, several studies have indicated that manipulations of state-like variables (e.g., mood or stress) can influence levels of impulsivity demonstrated on the tasks. Furthermore, environmental context (in the form of physical setting, or contextual cues) has a demonstrable effect on tasks relevant to alcohol-related risky behaviors (e.g., ad lib drinking tasks). Importantly, this effect of context on behavior is dependent on the individual's alcohol expectancies. It is unknown, however, whether alcohol-related …

North American River Otter (Lontra Canadensis) Presence And Habitat Analysis In Florida As Compared To Historical Data, Samantha Wilber

USF Tampa Graduate Theses and Dissertations

North American river otters are considered common in the state of Florida, but their populations have not been studied since the 1980’s. Since that time, Florida’s human population has more than doubled, and many natural areas of Florida have been developed. The aim of this study was to determine the presence or absence of river otters at locations in Florida which they historically inhabited. Forty-six sample sites where otters were historically found were obtained from the Florida Museum of Natural History Mammals Master Database (FMNH MMD).

Linking Insomnia And Suicide Ideation: The Role Of Socio-Cognitive Mechanisms In Suicide Risk, Melanie Lauren Bozzay

USF Tampa Graduate Theses and Dissertations

Despite what is known about predictors of suicide risk and consequences of insomnia, research has yet to delineate mechanisms that may explain the known relationship between insomnia symptoms and suicide risk. There is some disagreement in the literature regarding whether this relationship could be primarily explained by recent depressive symptoms, or whether there may be other explanatory factors related to sleep deficits. The present study addressed this contention in the literature by examining 1) whether socio-cognitive variables (e.g. fatigue, appraised social problem-solving ability, and hopelessness) explained this insomnia-ideation relationship, and 2) whether these variables contributed some explanatory variance in suicide …

Effect Of Empathy On Death Penalty Support In Relation To The Racial Divide And Gender Gap, Brian Godcharles

USF Tampa Graduate Theses and Dissertations

This study aimed to examine previous empirical literature indicating that death penalty support contains a divide among Blacks and Whites and a gap among males and females. Previous literature has indicated that there has been a persistent racial divide and gender gap in death penalty support that has spanned over 60 years of research. Attempts to attenuate these divides have failed to fully explain why Whites are more likely than Blacks to support the death penalty and men are more likely than women to support the death penalty. This study proposes the use of empathy to control for these divides …

Finding A Home: Latino Residential Influx Into Progress Village, 1990-2010, Christopher Julius Pineda

USF Tampa Graduate Theses and Dissertations

Progress Village in Tampa Florida was developed in the late 1950s in response to the dislocation of black families during the construction of Interstate-4. Furthermore this community became an opportunity for many black and more specifically, African American families, to live in a community devoid of racist attitudes and tensions rampant in inner city Tampa at the time. For over thirty years this community’s residential population was overwhelmingly (90 percent) black or African American. In the 1990s though this community would begin to experience the first wave of Latino residents and by 2000 this group would comprise over 2 percent …

A Bat-Guano-Derived Δ15N And Δ13C Record Of Paleoenvironmental Change: Zidită Cave, Romania, Daniel Martin Cleary

USF Tampa Graduate Theses and Dissertations

Because nitrogen isotopes are fractionated along the soil-plant-insect-bat-guano pathway, it may be possible to reconstruct environmental and climatic changes reflected in the nitrogen isotopic composition of guano. A 1.5-m core of bat guano from Zidită Cave (western Romania) provides a record of climatic and anthropogenic influence on the regional nitrogen cycle and paleoenvironmental controls on nitrogen transforming processes. Increasing and decreasing trends of nitrogen isotopic composition (δ¹⁵N values) correspond well with changes in the influence of farming practices, deforestation, and forest expansion. These influences likely had a significant effect on the openness of the nitrogen cycle, resulting in …

The Influence Of Types Of Homework On Opportunity To Learn And Students' Mathematics Achievement: Examples From The University Of Chicago School Mathematics Project, Yiting Yu

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Public views on assigning students mathematics homework have been controversial. Although homework is designed for students to complete during non-school hours (Cooper, 1989), many see homework as excessive pressure on students. Most research placed their focus on the influence of the time spent on homework or the amount of homework on student achievement. Few studies have addressed the impact of types of mathematics homework. The purpose of this study is to examine the role of homework types in influencing opportunity to learn (OTL) on student achievement.

This quantitative study used subsets of a large existing dataset collected by University …
